An 18-month-old boy, with complete immunization schedule to date, who consults the Emergency Department for right knee swelling after playing in the park, without obvious trauma. In the directed anamnesis, the mother refers that an uncle of hers had similar problems. The ultrasound examination is compatible with hemarthrosis and in the analytical analysis only an APTT lengthening of 52'' (normal 25-35'') stands out. What is the most probable diagnostic hypothesis?

Two propositi of this family, an 18-year-old male and a 33-year-old female, both with a history of epistaxis, bruising, bleeding from the gums, epistaxis, hemarthrosis, and hematoma, were analyzed. Also additional members of the same family with no bleeding history were also studied. The propositi showed normal vWF activities, low FVIII activity; one of them had been diagnosed as having hemophilia A and the other was a hemophilia A carrier. Both showed a very poor response to treatment with FVIII concentrates and desmopressin (DDAVP) but a good clinical response to cryoprecipitate. APTT was prolonged and no inhibitory activity was noticeable in their plasmas. Thirty-five units per kilogram body weight of Hemofil M was infused to both propositi and FVIII reached basal level within 60 minutes of the infusion. No FVIII response at all was observed in the female after intravenous DDAVP administration. However, the male who received the infusion of 35 U/kg body weight of Humate-P achieved a normal FVIII level that was maintained for 12 hours. Multimeric analysis of vWF was normal in all the members studied. Von Willebrand factor domain for FVIII binding was assayed in the two propositi and in six other members of the same family by using a non-isotopic and sensitive method, a modification of the one previously described, using the Hemofil M concentrate as exogenous FVIII. The data obtained showed that both propositi had similar binding to that observed by using plasma of a patient with severe von Willebrand disease. Furthermore, five siblings had a decreased binding of vWF to FVIII, when compared with plasma from normal individuals or patients with hemophilia A. We also observed that, for screening purpose, the ratio of bound FVIII/immobilized vWF (at saturation of the anti-vWF and offering of 1 U/ml of exogenous FVIII) distinguished two levels of abnormality (normal range 0.70-1.15, propositi 0.004-0.007, and remaining members affected 0.25-0.42). The most probable explanation is that the propositi are homozygous or double heterozygous, the other five siblings affected being heterozygous for a recessive vWF defect. This more accessible assay presented here may be of help in routine analysis for diagnosing this type of von Willebrand disease, which has important implications for therapy and genetic counseling." }, { "id": "pubmed23n1089_3373", "title": "Diagnostic Challenges in Children With Congenital Bleeding Disorders: A Developing Country Perspective.", "score": 0.017704661182922053, "content": "To assess the frequency and characteristics of children with inherited bleeding disorders that were initially misdiagnosed, leading to inappropriate disease management.

Dentists are often anxious about delivering treatment to this special group of patients. In the Irish Republic, patients with inherited bleeding disorders have their dental care co-ordinated centrally at the National Centre for Hereditary Coagulation Disorders (NCHCD), St James's Hospital, Dublin. Dental care is normally integrated with routine outpatient haematological appointments. This ensures regular monitoring of oral health and the early treatment of any hard/soft tissue pathology. This article describes, in simple diagrammatic form, the normal coagulation mechanism (Figures 1 and 2), explains common coagulation terms (Appendix 1), and examines the three most common congenital bleeding disorders: haemophilia A, haemophilia B, and von Willebrand disease. General recommendations based on the current literature are provided with respect to procedures that are appropriate to perform in a general dental practice setting. Although not discussed in this article, it is important to note that non-coagulation bleeding disorders also exist. These include: hereditary haemorrhagic telangiectasia; blood vessel wall defects resulting from connective tissue disorders such as Marfan syndrome and Ehlers-Danlos syndrome; and, platelet disorders such as Bernard-Soulier syndrome, resulting in defective platelet adhesion." }, { "id": "pubmed23n0780_13321", "title": "Screening bleeding disorders in adolescents and young women with menorrhagia.", "score": 0.015617875056999544, "content": "Chronic menorrhagia causes anemia and impairment of life quality.

A form including demographic characteristics of the patients, bleedings other than menorrhagia, familial bleeding history, characteristics of the menorrhagia, and impairment of life quality due to menorrhagia was filled out by the researcher during a face-to-face interview with the patient. A pictorial blood assessment chart was also used for evaluation of blood loss. All patients underwent pelvic ultrasound sonography testing and women also received pelvic examination by gynecologists. Whole blood count, peripheral blood smear, blood group, serum transaminases, urea, creatinine, ferritin, PFA-100, PT, aPTT, INR, TT, fibrinogen, VWF:Ag, VWF:RCo, FVIII, and platelet aggregation assays were performed. Platelet aggregations were studied by lumiaggregometer. Out of 75 patients enrolled, 60 patients completed the study. The mean age was 20.68±10.34 (range: 10-48) years and 65% (n=39) of the patients were younger than 18 years. In 18 (46%) of the adolescents, menorrhagia subsided spontaneously. In 20% (n=12) of the patients, a bleeding disorder was detected (1 case of type 3 von Willebrand disease, 2 patients with low VWF:Ag, 1 case of probable von Willebrand disease, 3 cases of Bernard-Soulier syndrome, 2 cases of Glanzmann thrombasthenia, 2 cases of immune thrombocytopenic purpura, 1 case of congenital factor VII deficiency). In patients with menorrhagia, at least complete blood count, peripheral smear, aPTT, PT, VWF:Ag, VWF:RCo, FVIII, and fibrinogen assays must be performed. When there is history of nose and gum bleeding, platelet function assay by lumiaggregometer must also be performed. In nearly 50% of adolescents, menorrhagia is dysfunctional and transient. Detailed coagulation assays can be postponed in adolescents if bleeding history other than menorrhagia and/or family history of bleeding and/or parental consanguinity is absent.

The diversity of this collagen dysplasia and its combination with other abnormalities make it difficult to understand physiopathologically. A case of Ehlers-Danlos syndrome is reported, which is novel owing to its combination with clotting abnormalities and especially with muscular dystrophy. To our knowledge this has not previously been reported. The patient was a young man aged 16 years who presented with Ehlers-Danlos syndrome satisfying Perelman's diagnostic criteria. His father and two brothers had comparable clinical symptoms, but his mother and sister were healthy. The four male subjects had an increased cephalin-kaolin time, reduced levels of factor VIII and Willebrand's factor (but without haemophilia A or Willebrand's disease), and, especially, an abnormal platelet ATP secretion. The proband alone had muscular disease with bilateral quadriceps fatigability and amyotrophy. The muscle enzyme levels were greatly increased, the electromyographic trace was myogenic, and the biopsy showed severe muscular dystrophy. This new observation poses the problem of the relation between clotting abnormalities and collagen abnormalities in the Ehlers-Danlos syndrome. It is difficult to classify this case within any of the 11 known types because of its muscular manifestations.

Most heterozygotes, with few exceptions, do not have a bleeding diathesis. BSS presents as a bleeding disorder due to the inability of platelets to bind and aggregate at sites of vascular endothelial injury.

Some of these conditions include von Willebrand disease, scurvy, diseases of platelet dysfunction, deficiency of other coagulation factors like V, VII, X, or fibrinogen, Ehlers-Danlos syndrome, Fabry disease, disseminated intravascular coagulation, and child abuse. In von Willebrand disease, bleeding symptoms can be similar to mild hemophilia, but patients with von Willebrand disease have more mucosal bleeding compared to musculoskeletal bleeding seen in hemophilia. Von Willebrand disease is diagnosed by checking for von Willebrand factor antigen or von Willebrand factor multimers. [40] Similarly, in scurvy, Ehlers-Danlos syndrome, and Fabry disease; also, the bleeding is usually mucosal, unlike hemophilia, where it is musculoskeletal. In scurvy, there is a deficiency of vitamin C. [41] In Ehlers-Danlos syndrome, the skin is hyperextensible, and joints are hypermobile. The diagnosis is usually through clinical features, genetic testing, and tissue biopsy. [42] Similarly, in Fabry disease, patients may also have other organs being affected, including kidneys and heart, and have skin lesions called angiokeratomas. They also have pain in the extremities. Fabry disease is usually diagnosed with clinical findings and genetic testing. [43] In cases of platelet dysfunction disorders, bleeding is usually mucocutaneous, unlike hemophilia. Usually, these disorders are diagnosed by platelet aggregation studies or platelet electron microscopy. [44] In the deficiency of other coagulation factors, musculoskeletal bleeding is uncommon. In fact, sometimes thrombosis can occur, especially in patients with factor VII or fibrinogen deficiency or in patients with combined factor V and VIII deficiency. Specific coagulation factor assays usually confirm the diagnosis. Disseminated intravascular coagulation (DIC) that mimics hemophilia is hard to differentiate, but usually, there is an underlying condition in DIC, for example, acute promyelocytic leukemia.

The objective of this article is to highlight the value of ultrasounds in the diagnosis and control of the evolution of musculo-skeletal problems in haemophilia patients. To this end, we have performed a literature search in the PubMed, Web of Science(®) (WOS) and SciVerse bases, using the following keywords: hemophilia or haemophilia and ultrasonography (US), ultrasound, echography and sonography. The search was limited to studies published in English between the years 1991 and 2011, finding a total of 221 references. After reviewing the title or abstract for evidence of the use of US for the diagnosis of musculo-skeletal lesions in haemophilia, we selected 24 of these references. We added data collected from our experience to the most important data found in the references. Our main conclusion is that US is highly valuable for the diagnosis of musculo-skeletal diseases in haemophilia. It is a fast, effective, safe, available, comparative, real-time technique that can help us confirm the clinical examination. It is particularly important in acute haemarthrosis, as it can be used to objectively identify the presence of blood in the joints, measure its size, pinpoint its location, assess its evolution and confirm its complete disappearance." }, { "id": "pubmed23n1125_14898", "title": "The value of ultrasonography in detecting early arthropathic changes and contribution to the clinical approach in patients of hemophilia.", "score": 0.00980392156862745, "content": "PURPOSE\\AIM: Hemophilia affects the blood clotting process, is a genetic disease characterized by recurrent bleeding. The hemophilia early arthropathy detection with ultrasound (HEAD-US) procedure and scoring method were designed for the detection of early changes in affected joints of patients.

It was aimed to investigate the effectiveness of HEAD-US scoring in showing early joint damage in subclinical hemophilia cases and its contribution to treatment. The present study included 50 hemophilia patients who were admitted to Departments of Pediatric and Adult Hematology for routine follow-up. During routine follow-up controls, patients were scored by physical examination and HJHS 2.1 and by ultrasonography and HEAD US. Statistical tests were used to analyze joint health status and the results of US examination in the patient group. A total of 294 joints (elbow n = 100, knee n = 94, ankle n = 100) were evaluated by ultrasonography. The mean HJHS and HEAD-US scores of the patients were 14.94 ± 15.18 and 15.6 ± 12.6, respectively.

On each office day, a brief questionnaire (Q1) including five questions investigating insomnia symptoms and current use of treatment was administered to the first 10 patients who referred to the GP office for reasons associated with their own health. The first patient of each day classified as insomniac underwent a second investigation based on a more detailed questionnaire (Q2) including demographic variables, socio-economic status, general medical conditions, severity, duration and clinical features of insomnia, daytime dysfunction, sleep satisfaction and therapeutic management. In a primary care setting, insomnia symptoms are often persistent (&gt;1 year), recurrent (&gt;1/week) and accompanied by daytime consequences. Two out of three patients with insomnia symptoms are dissatisfied with their sleep. In most cases, insomnia symptoms are underrated both by the patients, who cover the problem or reject treatment, and by the GP, who limits intervention on the sleep disorder (scarcely modifying ongoing therapy both in responders and in non-responders). In responders, treatment was confirmed in 91% of cases and discontinued in only 2%. When there was no improvement, or if insomnia symptoms became worse (non-responders), treatment was nevertheless continued in 74.5% of cases, either maintaining the same ineffective dose, increasing the dose, or adding another drug or a non-pharmacological procedure. Regardless of specific medication, the Italian GP privileges the pharmacological approach, which is fourfold more frequent than non-pharmacological therapy (78.6 versus 18.2%). Non-benzodiazepine hypnotic drugs are mostly prescribed when the GP decides to apply medication in previously untreated patients with insomnia symptoms. Self-administration is not unusual among the patients with insomnia symptoms and is more common among non-responders. Italian GPs tend to confirm the ongoing therapy and avoid re-evaluation of the treatment regimen. Limited use of non-pharmacological treatment in the Italian primary care setting is in line with this conservative approach of the GPs who tend to be problem-solvers rather than problem-seekers." }, { "id": "pubmed23n1022_10550", "title": "Perampanel in chronic insomnia.", "score": 0.01465923291358262, "content": "Insomnia is the most prevalent sleep disorder in the general population, and one of the most frequent reasons for consultation in the Sleep Units.

He was previously followed by a psychiatrist for 2 years for additional diagnoses of insomnia, bipolar disorder, anxiety, attention deficit hyperactivity disorder, and intellectual disability. He has tried and (apparently) failed multiple psychotropic trials including stimulants, nonstimulants, mood stabilizers, atypical antipsychotics, and nonbenzodiazepine hypnotics. He has a delayed sleep onset and frequent night awakenings each night for the past 3 months, during which he \"screams, cries, and thrashes and can stay up for over an hour.\" His behaviors are described as irritable, self-injurious, and aggressive with no clear pattern of triggers according to his mother. He is nonverbal and communicates by leading and rarely pointing. The patient's current medication regimen includes clonidine 0.2 mg at night, lorazepam 1.5 mg as needed at night, olanzapine 5 mg twice daily, and diphenhydramine as needed for sleep/agitation. His mother is concerned that he is developing \"tolerance\" to the regimen and wants to wean him off some of the medications. His mother is struggling to take care of the patient given his worsening behavior and body habitus (body mass index &gt;99%; z = 3.41).There is a family history of depression, anxiety, bipolar disorder, and autism. He has a 3-year-old sister, who is also diagnosed with ASD, though she is not as severely impacted. His mother's partner recently moved in along with 2 children of his own, aged 3 and 4 years. Sam attends a specialized school, where he receives behavior therapy and occupational therapy. He has undergone inpatient pediatric hospitalization twice, 1 time for 3 weeks and the other for 6 days, for aggressive behavior, and in both instances, he was discharged before inpatient psychiatric placement because of a lack of available beds.After urgent consultation with your local developmental and behavioral pediatrician, a slight reduction was made in the lorazepam because of concerns about tolerance and side effects. However, within a week of this, he was brought to the emergency department for continued self-injurious behavior and increased trouble with sleeping. His mother voiced concerns about his safety in the home, which were particularly related to aggression toward his younger sister. He was admitted to the pediatric inpatient floor for observation, and medication adjustment (increasing olanzapine), which was initially helpful in improving behavior, but mostly behavioral/environmental strategies were used to soothe him, including frequent wagon rides through the hospital corridors.Despite the patient being stable from the medical standpoint, Sam's mother did not feel comfortable taking him home. Social work contacted local community mental health services to pursue outpatient resources and respite care options and sought inpatient pediatric psychiatry. After several failed attempts to find placement, he remained in pediatric inpatient care for 1 and a half months with no acute medical interventions other than his oral medications.He was finally accepted to the in-state pediatric psychiatric facility when a bed was available. During his week-long stay, he had further medication adjustments with a decrease in olanzapine and optimization of his clonidine dose. During his psychiatric hospital stay, care coordination succeeded in arranging center-based applied behavior analysis interventions and respite care and parent training for his family. Sam began to show improvement in his overall agitation and aggression, requiring less clonazepam, and his mother then maintained outpatient follow-up.The day before discharge, you visit him in the hospital, and a medical student asks you why he was in the hospital for so long.

Although cognitive behavioral therapy for insomnia (CBT-I) is considered the standard of care [1], several monotherapies, including sleep restriction therapy, stimulus control therapy, and relaxation training are also recommended in the treatment of chronic insomnia [2]. CBT-I is a multimodal intervention comprised of a combination of behavioral (eg, sleep restriction, stimulus control) and cognitive therapy strategies, and psychoeducation delivered in 4 to 10 weekly or biweekly sessions [3]. Given that insomnia is thought to be maintained by an interaction between unhelpful sleep-related beliefs and behaviors, the goal of CBT-I is to modify the maladaptive cognitions (eg, worry about the consequences of poor sleep), behaviors (eg, extended time in bed), and arousal (ie, physiological and mental hyperarousal) perpetuating the insomnia. CBT-I is efficacious when implemented alone or in combination with a pharmacologic agent. However, because of the potential for relapse upon discontinuation, CBT-I should be extended throughout drug tapering [4]. Although the treatment options should be guided by the available evidence supporting both psychological therapies and short-term hypnotic treatment, as well as treatment feasibility and availability, treatment selection should ultimately be guided by patient preference [5]. Despite its widespread use among treatment providers [6], the use of sleep hygiene education as a primary intervention for insomnia should be avoided.

In industrialized countries, the prevalence of insomnia ranges between 10% and 48%, depending on the methodology and the measured time interval. However, few studies have examined the relationship between insomnia and mental disorder diagnoses. This epidemiological study on insomnia complaints was conducted on 5 622 subjects representative of the non-institutionalized French population aged 15 years or over. Sixteen interviewers using the Sleep-EVAL expert system performed telephone interviews. Insomnia complaints (defined as difficulty initiating or maintaining sleep, feeling unrefreshed at awakening accompanied by dissatisfaction with sleep quality or quantity, or use of sleep-promoting medication) were observed in 18.6% (95% confidence interval: 17.6% to 19.6%) of the sample. The median duration of insomnia complaints was five years. Regional variations in the prevalence of insomnia complaints were observed in France. In North 2 and Center 4 regions, the prevalence of insomnia complaints was higher compared to the rest of France with a relative risk of 1.4 (95% confidence interval: 1.1-1.6) time superior for the North region and 1.3 (95% CI: 1.0-1.6) for the Center 4 region. The lowest prevalence was registered in the Mediterranean area. In most regions, the prevalence of insomnia complaints was higher in women than in men with the exception of the South and West regions where the prevalence was similar. Subjects with insomnia complaints consulted more frequently compared to the rest of sample with an odds ratio of 3 to 1 [95% CI: 2.8 to 4.1]. Close to 20% of subjects were being treated for a physical disease at the time of the survey; subjects with insomnia complaints being twice more numerous (34.3%) than the rest of the sample (15.9%; p&lt;0.001). To identify the main factors associated with insomnia complaints, socio-demographic and health variables were introduced in a multivariate model. Separated or divorced individuals (OR: 1.6); widowers (OR: 1.5); subjects aged between 45 and 65 years (OR: 1.4) or older than 65 (OR: 1.5); women (OR: 1.3); those with little or no education (OR: 1.4); and subjects living in the North region had higher reported insomnia complaints. Living in the East region (Mediterranean) was a protective factor (OR: 0.6). Furthermore, subjects with vascular diseases (OR: 2.0), musculo-skeletal diseases (OR: 2.0) or cardiac diseases (OR: 1.9) and those who had consulted a physician in the previous six months (OR: 2.7) had higher a probability of insomnia complaints. Subsequently, DSM IV insomnia diagnoses were examined in subjects who complained of insomnia. A diagnosis of primary insomnia was found in 7% of these subjects. A diagnosis of insomnia related to another mental disorder was found in 15.6% of insomnia complainers. A depressive disorder diagnosis was given in 10.8% of cases (mainly a major depressive disorder). This diagnosis was made more often among women and subjects of less than 65 years. An anxiety disorder diagnosis was given for 33.1% of insomnia complainers (an anxiety generalized disorder in about half the cases). About a quarter of insomnia complainers did not receive a diagnosis. This was the case more often for men and the subjects 65 years or older. If demographic and medical factors are relatively well documented at the epidemiological level, it is otherwise for psychiatric diagnosis associated with insomnia complaint. Very few studies in the general population have been done and still fewer of them have applied a positive and differential diagnosis process. In this study, we used the DSM IV classification to establish positive and differential diagnoses among subjects with insomnia complaints. Compared to other epidemiological studies, our study is distinguished by several aspects: 1) insomnia complaint had a narrower definition. It did not suffice that the subject reported insomnia symptoms, it was also necessary that the subject said s/he was dissatisfied with her/hr/his sleep or that s/he took measures to improve it (medication or sleep hygiene). This choice was motivated essentially by the fact that it is difficult, from a point of clinical point of view, to consider that an individual has insomnia solely based on the presence of symptoms, that, appreciated by a clinician, would resemble insomnia without that they make problem for the subject. 2) Several sleep habits were systematically collected. The majority of epidemiological studies are not centered on sleep problems, with the consequence that results do not allow a global view of factors that are associated with insomnia. 3) The various diagnostic categories of insomnia as well as elements of the differential diagnosis were applied. Thus, we can conclude that insomnia, as a diagnostic entity, including all its forms, is found in 5.6% of the French population. In the majority of cases, the insomnia complaint is part of the symptomatology of a mental disorder, mainly an anxiety disorder. This distinction is important since it helps the physician to determine therapeutic choices. To conclude, it is worthwhile to consider the number of insomnia complainers who had consulted a physician, mainly a general practitioner, in the six months prior to the study. This designates physicians as the first-line resource in the treatment and the prevention of sleep disorders." }, { "id": "pubmed23n0326_11643", "title": "What happens when doctors stop prescribing temazepam?

Bilateral postural hand tremor was also more prominent on the right hand. Fasciculations were observed both in the extremities and tongue. The remaining cranial nerves and cerebellar functions were intact. Sensation was normal except for slightly decreased vibratory sense in the distal part of the legs. Deep tendon reflexes including jaw jerk were increased with the exception of hyporeflexia of the right leg. Babinski sign was negative bilaterally.

Instead, a number of other possibilities have to be ruled out, such as multifocal motor neuropathy or spinal muscular atrophy. Tests used in the diagnostic process include MRI, clinical examination, and EMG.

Neurological examination revealed severe weakness and atrophy in the scapular muscles and proximal and distal muscles of the upper extremities. Fasciculations were also observed in the various muscles of the upper extremities. There was neither muscle weakness, atrophy nor fasciculation in either his face, neck muscles or lower extremities. He had no pseudobulbar or bulbar signs. Tendon reflexes were mildly hyperactive in the jaw and lower extremities, and normal in the upper extremities. There were no pathological reflexes, spasticity or sensory disturbances. The needle EMG study revealed denervation potentials in all muscles of the upper extremities examined. The nerve conduction study revealed no findings of the conduction block. Cervical spine X-rays revealed the narrowing of the spinal foramens at the left C3/C4 and bilateral C4/C5, C5/C6, and C6/C7 intervertebral levels. In addition, magnetic resonance imaging (MRI) revealed compressions of the cervical cord at C4/C5 and C5/C6 intervertebral levels. These clinical and neuroradiological findings resembled those of the cervical spondylotic amyotrophy (CSA). However, the motor evoked potential (MEP) study revealed the pyramidal tract dysfunction above the levels of the pyramidal decussation. Furthermore, brain MRI revealed abnormal foci in both internal capsules which were characterized by hyperintense relative to cortical gray matter on T2-weighted images and still hyperintense to white matter on proton-density-weighted images. In addition, T2-weighted images demonstrated a low signal within the motor cortex and hyperintense lesions in the white matter of the precentral gyri. These MRI findings indicated the degeneration of the pyramidal tract and corresponded to those found in the patients with amyotrophic lateral sclerosis (ALS) which have been recently reported. It has been difficult to distinguish ALS from CSA. However, MEP and brain MRI studies were useful for distinguishing these two diseases in this patient. In addition, this patient showed typical MRI findings suggesting the degeneration of the pyramidal tract, although this patient had a relatively short course of illness and did not show obvious physical findings suggesting pyramidal tract dysfunction." }, { "id": "pubmed23n0309_14143", "title": "[Neurological CPC.57.

She was well until 1992 (75 years of age) when she noted an onset of weakness in her right leg which had got progressively worse. She was admitted to our service in July 1994. On admission, general physical examination was unremarkable. She was alert and well oriented without dementia. Higher cerebral functions were normal. Cranial nerves also appeared intact. She dragged her right leg in walking. Mild to moderate weakness (2/5 to 4/5) was noted in muscles in her right lower extremity more in the distal part. Deep tendon reflexes were within normal limits, and the plantar response was flexor bilaterally. Sensation was intact. Laboratory examinations were also unremarkable except for slight increase in CK which was 470 IU/l. CSF was also normal. EMG revealed neurogenic changes in the lower extremities. She was admitted to Aoki Hospital on October 21, 1994, by that time, her weakness in the right lower extremity had gotten worse in that the muscle strength of the right extensor hallucis longus was 0 and tibialis anterior 2; muscle atrophy was also prominent in her right leg; the right ankle jerk could not be elicited. In the subsequent course, weakness and atrophy appeared in her left lower extremity, however, upper extremities and cranial nerves had never been affected. Babinski sign was always negative. In February 1996, she developed delusional ideation of self persecution, and showed difficulty in communication with medical staffs. She developed fever of 38.7 degrees C on June 13, 1996 expired on the next day. The patient was discussed in a neurological CPC, and the chief discussant arrived at the conclusion that the patient had a form of spinal muscular atrophy. Opinions were divided between ALS and spinal muscular atrophy. Post-mortem examination revealed marked loss of anterior horn neurons in the lumbar area with astrogliosis. Bunina bodies were seen in some of the remaining neurons. No myelin pallor was noted in the pyramidal tracts, however, atrophy and loss of Betz cells were noted in the motor cortex. Other cortical areas were unremarkable. The neuropathologist arrived at the conclusion that the patient had ALS. This patient was unique in that she had asymmetric atrophy and weakness limited to the lower extremities. This is quite unusual as ALS of four years duration.

The sensitivity to vibrations on the Malleolus medialis on both sides was 0/8. The patient could walk only with the help of a Rollator. Over the three-year period following onset of symptoms the following tests were carried out: motor nerve conduction speeds of the N. tibialis and N. peronaeus, electromyogram of the N. tibialis anterior and the M. gastrocnemius, somatosensory evoked potentials (SSEP) of the N. tibialis, which indicated a lesion in the peripheral nerves or nerve roots. Cranial computed tomography (CCT), CT scan of the lumbar spine (L3-S1) and angiological investigation elicited no significant pathological findings. An MRI of the thoracal spine showed a vertebra-sized dorsal tumor pressing on the spinal cord from left to right. By means of microsurgery the spinal tumor was completely removed. Suspected meningeoma was confirmed by histological analysis. During the post-surgical period, the incomplete paraplegia quickly regressed, and 7 weeks after the removal of the spinal meningeoma the patient was able to climb stairs. In case of slowly-developing paresis of the legs in diabetic patients, diabetic polyneuropathy should not be diagnosed without careful consideration, and rare spinal tumors should be considered as part of the differential diagnosis, especially if the blood glucose level is normal, and intensive physiotherapy brings no improvement in the patient's condition." }, { "id": "pubmed23n0566_18451", "title": "[Familial spastic paraplegia with severe amyotrophy of the hands.

Electromyogram (EMG) detected such denervation potentials as fibrillation potentials, fasciculation potentials, positive sharp waves and polyphasic or giant MUPs diffusely in the limb muscles. Peripheral nerve conduction study detected neither conduction block nor delay. Thus, she was diagnosed as suffering from ALS. However, since approximate 1 year after onset, her muscle weakness has gradually been getting better. Simultaneously, the dyspnea and dysphagia gradually improved. Two years after onset, an EMG examination detected chronic denervation potentials in the left musculus sternocleidomastoideus and a few on-going denervation potentials in the left musculus extensor carpi radialis, but no denervation potentials in other limb muscles. Fasciculation potentials were found in tongue muscles. Thus, the present case was thought to have a reversible motor neuron syndrome clinically quite similar to ALS. A mild increase in IgE (346 U/ml) and a low-titer IgM-class anti-GM1 antibody were found in her serum though its pathological significance was uncertain.

This case demonstrates that association of asymmetrical focal cortical and subcortical features remains the clinical hallmark of this condition. There are no absolute markers for the clinical diagnosis that is complicated by the variability of presentation involving also cognitive symptoms that are reviewed in the paper. Despite the difficulty of diagnosing CBD, somatosensory evoked potentials, motor evoked potentials, long latency reflexes, and correlations between results on electroencephalography (EEG) and electromyography (EMG) provide further support for a CBD diagnosis.

In the present study we report the clinical, electrophysiological and MRI features of a group of Italian patients, with review of the literature. Moreover we propose an optimized MRI protocol for patients with suspected or diagnosed HD in order to make an early diagnosis and a standardized follow up. Eight patients with clinical suspicion of Hirayama disease underwent evaluation between January 2007 and November 2013. All patients underwent standard nerve conduction studies (NCS), electromyography (EMG) and motor/sensory evoked potentials (MEP/SEP). Cervical spine MRI studies were conducted with a 1.5 Tesla MRI scanner in neutral and flexion position, including sagittal T1-weighted sequences and sagittal and axial T2-weighted sequences. The following diagnostic features were evaluated: abnormal cervical curvature, localized cervical cord atrophy in the lower tract (C4-C7), presence of cord flattening (CF), intramedullary signal hyperintensity on T2 weighted sequences, anterior shifting of the posterior wall of the cervical dural sac (ASD) and presence of flow voids (EFV) in the posterior epidural space during flexion. All patients complained of weakness in hand muscles as initial symptoms, associated with hand tremor in three of them and abnormal sweating of the hand palm in two of them. No sensory deficits and weakness at lower limbs were reported by any patients. Distal deep tendon reflexes at upper limbs were absent in all patients with the absence of the right tricipital reflex in one of them. Deep tendon reflexes at lower limbs were normal and no signs of pyramidal tract involvement were present. The clinical involvement at onset was unilateral in six patients (three left-sided and three right-sided) and bilateral asymmetric in two of them, with the right side more affected. With the progression of the disease all patients but one experienced weakness and wasting of hand muscles and forearm bilaterally, but still asymmetric. The duration of the progression phase of the disease ranged from eight months to three years. In all patients, NCS and EMG findings were consistent with a spinal metameric disorder involving the C7-T1 myotomes bilaterally; sensory conduction and electrophysiologic features at lower limbs were normal. MEP and SEP were normal and we did not observe the disappearance of the spinal potential during the neck flexion in any of the patients. MRI is the best diagnostic tool in the diagnosis of HD; it can confirm clinical diagnosis and exclude other conditions responsible for the neurological deficits leading to a correct patient management and therapy, limiting arm impairment. On MRI all patients had loss of the normal cervical lordosis (100%). Five patients had loss of attachment of posterior dural sac and anterior dural shift on flexion MRI with presence of flow voids from venous plexus congestion (62.5%); three patients had no anterior dislocation of the dural sac and no epidural vein congestion. Two patients showed localized cord atrophy, one at C5-C6 and the other at C6-C7 level (25%). Three patients had T2 intramedullary hyperintensities (37.5%) and cord flattening (CF) was present in 5 patients of 8 (62.5%). HD is a rare entity and a self-limited condition, but it has to be early differentiated from other diseases that may determine myelopathy and amyotrophy to establish a correct therapy and limit arm impairment. MRI is very important to confirm the clinical suspect of HD and a standardized MRI protocol using axial and sagittal images in both neutral and flexing position is needed, in order to diagnose and follow up affected patients." }, { "id": "pubmed23n0389_20579", "title": "[Regarding the clinical diagnosis of the monotopical spinal forms of multiple sclerosis.

The objective of this study was to study the clinical symptoms and electrophysiological features of C6-7 myelopathy. This study was conducted at the Department of Orthopedic surgery, Yamaguchi University Graduate school of medicine, Japan. A total of 20 patients with cervical compressive myelopathy were determined by spinal cord-evoked potentials or a single level of obvious magnetic resonance imaging (MRI)-documented cervical spinal cord compression. Neurological examinations included manual muscle testing and investigation of deep tendon reflex, including Hoffmann sign, and of sensory disturbance areas. Motor-evoked potentials (MEPs), compound muscle action potentials (CMAPs) and F-wave were recorded from bilateral abductor digit minim and abductor halluces muscles. Central motor conduction time was calculated as follows: MEPs latency-(CMAPs latency+F latency-1)/2 (ms). Eighteen patients (90%) had negative Hoffmann sign. Eight patients (40%) had no sensory disturbance in the upper limbs and 8 patients (40%) had no muscle weakness in the upper limbs. We determined that patients had cervical myelopathy when their central motor conduction time measured in abductor digit minim was longer than 6.76 ms (+2 s.d.). Using this definition, the sensitivity for myelopathy was 42.8%. Patients with C6-7 myelopathy may lack clinical symptoms in their hands and central motor conduction time measured in abductor digit minim tended to be less prolonged, and it only showed symptoms in their lower limbs as gait disturbance. Surgeons should bear in mind the possibility of disorders of caudal C6-7 when they encounter patients with no or few symptoms in their hands and with leg weakness or numbness." }, { "id": "pubmed23n0259_1319", "title": "[A 65-year-old woman with dysarthria, dysphagia, weakness, and gait disturbance].", "score": 0.009523809523809525, "content": "We report a 65-year-old woman with progressive dysarthria, dysphagia, weakness, and gait disturbance.

The operation brought about stabilization or fairly good recovery over the 18 months following at least. From a clinical aspect, the \"Lhermitte sign\" or objective sensitive deficit are strongly significant for cervical myelopathy. On the contrary, diffuse fasciculations specially in the tongue seem to be mostly found in lateral amyotrophic sclerosis, whereas they are restricted into the paralysed area in cervical myelopathy. Electromyographic examination is decisive: simple activity with high frequency motor units (increased amplitude and polyphasic waves) or \"preponderant potentials\" into a cranial nerve territory or three segments of the lower limbs are frequently found in lateral amyotrophic sclerosis. These electromyographic features are less significant in the upper limbs.

Oral prednisolone (50 mg/day with gradual tapering) alleviated both her symptoms and the gadolinium-enhancement of the right brachial plexus.

The subjects were 33 patients presenting with paresis of one leg, 17 of organic origin and 16 of non-organic origin (hysteria). To test the abductor sign, the examiner told the patient to abduct each leg, and opposed this movement with his hands placed on the lateral surfaces of the patient's legs. The leg contralateral to the abducted one showed opposite actions for organic paresis and non-organic paresis: for example, when the paretic leg was abducted, the sound leg stayed fixed in organic paresis, but moved in the hyperadducting direction in non-organic paresis. Hoover's sign was used for comparison in the same patients. The abductor sign gave the correct classification for all 33 cases. Hoover's sign was reliable if the results were carefully interpreted, but it was non-diagnostic for 16 patients because of strong hip extensors and in two because of strong hip flexors. Two patients with non-organic paresis succeeded in tricking the examiner by pretending full effort to lift the paretic leg. The abductor sign is a useful test to detect non-organic paresis, because (1) it is difficult for a hysterical patient to deceive the examiner, (2) the hip abductor is one of the most commonly involved muscles in pyramidal weakness, and (3) the results are easily visible as movement or non-movement of the unabducted leg." }, { "id": "pubmed23n1058_8240", "title": "Hirayama Disease Presenting as 4-Limb Paresthesia.", "score": 0.009009009009009009, "content": "Hirayama disease is a rare clinical entity that presents typically as a unilateral, slowly progressive arms weakness, mostly occurring in young men.

The aim of this multicentric French symposium was to prospectively study the results of current therapeutic options in order to propose scientifically proven options. Three prospective studies were carried out in order to answer to these questions: (1) is it possible with anatomical reduction and stable fixation to lower the non union and osteonecrosis rate? (2) is functional treatment of Garden 1 fractures successful in more than 65 years patients? (3) what criteria are useful to choose the kind of arthroplasty for more than 65 years patients? For the 64 patients between 50 and 65 years old included in the first study, 44 ORIF and 17 prostheses were performed. No open reduction was performed in this series despite a 34% malreduction rate. The risk for displacement after functional treatment of Garden 1 fractures is 31%. For patients over 65 years old, almost fractures are treated in this series by an arthroplasty. The one-year mortality rate after displaced femoral neck fracture was 17%. Functional results were better in total hip prosthesis group than in bipolar or unipolar group. Non cemented stems were not safer than cemented ones in frail patients. For young patients, ORIF should be the treatment of choice: the initial displacement and its effects on the femoral head vascularisation, the quality of reduction and fixation are the two most significant factors for good outcome. For Garden 1, fractures in patients 65 years old or more, it is proposed to performed an internal fixation despite in two thirds of the cases, it should be unnecessary because non identification of predictive factors of failure. For patients over 65 years old, the type of arthroplasty to perform in displaced fractures is to be chosen according to the preoperative mobility and comorbidities. Because of acetabular erosion with long-term follow-up, it is clearly indicated to perform total hip replacement for patients with life expectancy of 10 years or more. For frail patients, unipolar arthroplasty is the best option. The place for bipolar or uncemented implants is not yet well-defined and more prospective trials are needed.

And next we compared fracture reduction of broken acetabulum and assesement of clinical treatment. The types of fractures were defined according to classification of Judet-Letournel. The criteria of fracture reduction due to Letournel. The clinical result was based on Merle d'Aubigne-Matta scale. In the group of treated patients till 3 weeks after trauma, we have received 83.8% of very good and good results, 6.9% fair results and 9.3% poor results. During fracture reduction: 75% very good, 4% in secondary joint congruence, 17.8% fair and 3.2% poor. After fair reduction there was always the right congrugence between the head and acetabulum. The displacements to 3 mm were left in more cases as a part after weight-bearing area. In trauma fracture trated after 3 weeks, the result was very good and good 66.1%, fair 14.8% and poor 19.1%. During fracture reduction: 49.7% very good, 4.4% secondary joint congruence, 32.8% fair and 13.1% poor. We have noticed the crucial corelation between fracture reduction and the final result of treatment. Additional traumae, especially head with long time loss of consciousness and the traumae of chest with insufficient breathing have indirect infulence on treatment results causing the longer operation waiting. The complexity fractures also indirectly influence on the result of treatment decreasing the chances on anathomical fracture reduction." }, { "id": "pubmed23n0527_18258", "title": "Displaced intracapsular hip fractures in fit, older people: a randomised comparison of reduction and fixation, bipolar hemiarthroplasty and total hip arthroplasty.", "score": 0.014377470355731226, "content": "To compare internal fixation, bipolar hemiarthroplasty and total hip arthroplasty for the management of displaced subcapital fracture of the hip in previously fit patients of 60 years or older. A prospective randomised clinical trial. This multicentre trial was carried out in 11 Scottish hospitals with acute orthopaedic trauma units. The participants were 298 previously fit patients of 60 years or older with displaced subcapital hip fractures. The three surgical interventions for comparison were reduction and fixation, bipolar hemiarthroplasty and total arthroplasty (total hip replacement). Participating surgeons elected to randomise patients either among all three types of operation (three-way randomisation) or just between fixation and hemiarthroplasty (two-way randomisation). Clinical outcomes were mortality rates, reoperation rates and the complication rates associated with each procedure. Functional outcome was measured using a hip specific questionnaire [Johanson Hip Rating Questionnaire (HRQ)] and a general health status questionnaire [EuroQol 5 Dimensions (EQ-5D)]. Economic analysis compared the costs in the randomised groups of hospital treatment for the initial and subsequent admissions for up to 2 years. Altogether, 207 patients were randomised among all three trial operations, and 91 between just fixation and bipolar hemiarthroplasty. There were no statistically significant differences in clinical outcomes, but confidence intervals (CIs) were wide. At 2 years fixation failure reached 37% among those allocated fixation and 39% had undergone further surgery. Further surgery rates after hemiarthroplasty and total hip replacement were 5% and 9%, respectively. The group allocated fixation had significantly worse HRQ and EQ-5D scores than both arthroplasty groups at 4 and 12 months. At 24 months the results still favoured arthroplasty, but the overall HRQ and EQ-5D scores were no longer statistically significant. Total hip replacement had the best patient-assessed outcome scores. At 24 months the overall HRQ and EQ-5D scores for total hip replacement were significantly better than for hemiarthroplasty. The mean costs for the initial episode ranged from 6384 pounds Sterling for fixation to 7633 pounds Sterling for total hip replacement. The cost differences were largely due to differences in theatre costs and the cost of prostheses and hardware. The cumulative cost over 2 years of hemiarthroplasty was around 3000 pounds Sterling lower than for fixation (95% CI 1227 pounds Sterling to 7192 pounds Sterling). Compared with total hip replacement, both fixation and hemiarthroplasty were characterised by increased costs arising from hip-replacement admissions. When total (initial episode and subsequent hip-related admissions) hip-related costs are compared, total hip replacement conferred a cost advantage of around 3000 pounds Sterling per patient (versus hemiarthroplasty, 95% CI -pounds Sterling 1400 to 7420 pounds Sterling). In fit, older patients the results of the study show a clear advantage for arthroplasty over fixation; arthroplasty was more clinically effective and probably less costly over a 2-year period postsurgery. The results suggest that total hip replacement has long-term advantages over bipolar hemiarthroplasty, but these findings are less definite. This study provided support for the use of total hip replacement to treat displaced intracapsular hip fractures in fit, older patients. A larger trial comparing total versus hemiarthroplasty for these fractures could help to verify these findings. It would also be useful to know whether the findings of this study apply to patients aged 60 years or less who are usually treated with reduction and fixation. A clinical trial comparing arthroplasty versus fixation in patients older than 40 years would be a logical extension of the current study." }, { "id": "wiki20220301en047_45311", "title": "Hip fracture", "score": 0.013837997973025649, "content": "Surgery on the same day or day following the break is estimated to reduce postoperative mortality in people who are medically stable.

In elderly patients with displaced or intracapsular fractures many surgeons prefer to undertake a hemiarthroplasty, replacing the broken part of the bone with a metal implant.

Guidelines in the United Kingdom state that patients presenting with a neck of femur fracture should ideally be operated on the day of or the day after admission. However, there is a best practice tariff in the United Kingdom persuading trusts to operate on elderly patients with hip fracture within 36 hours of admission. Differing formats of daily trauma operating lists and varying consultant on-call schedules have the potential to affect a trusts ability to successfully meet such demands. This study retrospectively analyzed whether changing the on-call schedule from a system where the on-call consultant is changed on a daily basis to one which changes weekly resulted in a reduction in time to theater for such patients and an increase in best practice tariffs paid. With the initial rotation system, the average time to theater for a fractured neck of femur was 44 hours 46 minutes, with 44.7% of patients having a time to surgery of less than 36 hours. Patients in the modified system underwent surgery with an average time to theater of 32 hours 19 minutes. In 71.7% of these patients, time to surgery was less than 36 hours. This study demonstrates that changing the schedule to permit a consultant to have a 7-day period of trauma on call at a time instead of only 1 day dramatically reduced the time to theater for patients with hip fracture. This significantly reduced the number of these cases done outside 36 hours and increased trust financial reward." }, { "id": "pubmed23n0519_758", "title": "[Femoral neck fracture complicating orthopedic reposition of a dislocated hip: four cases].", "score": 0.012403446226975638, "content": "Posterior dislocation of the femoral head with fracture is an exceptional hip injury.

Irreducibility, instability, and more rarely accidental fracture of the femoral neck may also occur. We encountered this latter complication in four patients and report here its frequency and mechanism and propose preventive therapeutic measures. Seventy dislocations and fracture-dislocations of the hip were treated in our unit from March 1997 to February 2003. Among these cases, fourteen hip dislocations were complicated by femoral head fractures. Fracture of the femoral neck occurred during reduction in four. All four cases occurred in men, mean age 49.7 years, who were traffic accident victims (drivers or passengers). There were two Pipkin IV fracture-dislocations and two Pipkin II. The first reduction, achieved under general anesthesia in an emergency setting, was performed by an orthopedic surgeon in one patient and a general surgeon in three patients. Arthroplasty was used to treat the femoral neck fracture in three patients and pinning in one. We reviewed retrospectively the clinical and imaging data before and after reduction. Sub-capital fracture situated 4.0 cm (mean, range 3.5-4.5 cm) from the lesser trochanter occurred in all four cases. The head remained attached above and posteriorly to the acetabulum and was rotated less than 90 degrees . The fragment remaining in the acetabulum was displaced in two cases. In one patient, the fracture-dislocation of the head was associated with a fracture of the posterior rim of the acetabulum. This complication appears to result from an abrupt inappropriate reduction movement. The neck fracture would occur when capsulomuscular retention of the femoral head is associated with a head defect which catches on the rim of the acetabulum during the reduction movement. Neck fracture during reduction of traumatic hip dislocation is a serious complication. Prevention of this iatrogenic event requires a slow, progressive reduction limiting the trauma to a minimum; first intention open surgery may be required in selected cases." }, { "id": "pubmed23n0817_12964", "title": "[Hip fracture prosthetics in German trauma surgery.

The aim of this retrospective study was to evaluate a group of patients treated by osteo- synthesis for intra-capsular femoral neck fractures at our department, and to verify indication criteria and identify the therapeutic procedures that are best suited to our conditions. In the 1997-2001 period, a total of 81 patients with intra-capsular femoral neck fractures were operated on. Of these, 64 treated by dynamic hip screw (DHS) fixation were followed up for at least 5 years. There were 33 women and 31 men; the average age was 21.5 years (range, 21 to 74 years). The Garden classification was used to evaluate the displacement of femoral neck fractures. Preferably, osteosynthesis was carried out by closed reduction; only exceptionally was an extension device for the operating table used. A 135-degree sliding hip screw, with a short thread, directed to the head centre and a two-hole side plate were used most often.The average follow-up was 6.9 years. Evaluated were: the occurrence of late complications in relation to the length of time between injury and surgery, quality of fracture reduction, use of an anti-rotation screw and necessity of repeat surgery. Garden I or II fractures were diagnosed in 13 patients, 51 had Garden III or Garden IV fractures. Bone union without complications was achieved in 73.4 % of the patients within 12 months of surgery. Late complications were found in 26.6 %; of these, only one had Garden I fracture and the rest were Garden III and IV fractures. An anti-rotation screw was used in 39 patients (60.9 %) and its use had no effect on the development of late complications. Of the seven patients who developed pseudoarthrosis, the screw was used in four (57.1%); out of the nine patients with avascular necrosis, it was used in six (66.7 %). In the whole group, an unsatisfactory outcome of post-operative reduction was recorded in 29.7 %. In the patients with late complications this was found in 52.9 %, which was a statistically significant difference. Of the 17 patients with poor outcomes, 14 underwent total hip arthroplasty; in the patients with necrosis, arthroplasty was carried out at an average of 26 months post-operatively, in those with pseudoarthrosis it was at 7 months post-operatively. For the treatment of intra-capsular fractures of the femoral neck, surgery is the most frequent approach, but there are controversial views on various relevant issues. An important factor affecting the treatment outcome is the patient's bone quality. Our results show a direct relationship between the extent of fracture displacement and late complications, i.e., avascular necrosis and non-union. The quality of fracture reduction had a greater effect on fracture non-union than on the development of femoral head necrosis. The length of time between injury and surgery played a lesser role than it is believed. The use of an anti-rotation screw was not significantly related to the occurrence of late complications.

He had a severe closed head injury, bilateral pulmonary contusions, a fracture-dislocation of the right acetabulum, and an open injury of the right knee joint. The acetabular fracture pattern was an associated both-column fracture with the femoral head dislocated into a widely displaced posterior-column fracture line. The treating physicians agreed that it would be in the patient's best interest to take him to the operating room for emergent debridement and irrigation of his knee wound. At surgery, the patient also underwent attempted closed reduction of the acetabular fracture and placement of a skeletal traction pin. Radiographs obtained with the patient in traction showed reduction of the femoral head beneath a displaced superior dome fragment, but there remained a 12-mm gap in the posterior column, greater than 3 mm of step incongruity, and a large articular fragment entrapped in the anterior aspect of the hip joint. The patient remained intubated and sedated for several days. Upon weaning from the ventilator, it became evident that his head injury would prevent him from being able to give informed consent in the foreseeable future. The patient's family members refused to become involved with his care or medical decision-making, as he had become completely estranged from them as a result of his chronic alcohol abuse. Further delay in surgical treatment for the acetabular fracture would be associated with greater difficulty in obtaining an anatomic reduction, the potential for additional articular damage to the femoral head, and an increased risk of surgical complications. The question that arises is whether it is in the patient's best interest for the surgeon to proceed with open reduction and internal fixation of the acetabular fracture without having had the opportunity to fully inform him of the treatment options or the risks associated with an extensive surgical exposure." }, { "id": "pubmed23n0525_4407", "title": "[The hip head-conserving management of traumatic medial cervical hip fractures with big-fragment screws: a biomechanical examination].", "score": 0.009174311926605505, "content": "With the growing number of elderly people in the population and the increasing incidence of proximal hip fractures the question of how to manage the medial hip head fracture is of increasing importance.

MATERIAL AND METHODS In the period from 2003 to 2013, a total of 83 patients with periprosthetic femoral fracture after total hip replacement were treated at our clinic, namely 69 women and 14 men. The mean age in the cohort was 74 years (range 47-87). The Vancouver classification was used to grade the fractures. The cohort included 31 patients with type B1 fracture, 25 patients with type B2 fracture, 8 patients with type B3 fracture, and 19 patients with type C fracture. Altogether 80 patients underwent a surgery, 3 patients with non-displaced type B1 fracture were treated conservatively. The mechanism of injury was a simple fall in 75 % of primary endoprostheses and in 56% of revision endoprostheses. The average time to fracture was 7.6 years in primary implant and 3.6 years in revision endoprosthesis. In fractures with a well-fixed stem (type B1 and C) plate osteosynthesis was used. In case of a comminution zone, osteosynthesis was followed by spongioplasty. In patients with a loose stem (type B2 and B3), the fracture was treated with a revision uncemented stem. In two cases a combination of a revision stem and a massive corticocancellous bone graft was used. The evaluation was performed using the Harris Hip Score and the minimum follow-up from the surgery was 3 years. RESULTS In the group of patients with type B1 fracture, 28 patients were treated surgically. An excellent result was achieved in 22 patients (84%), in 4 patients (16%) the result was very good. The remaining 2 patients failed to meet the requirement of the minimum follow-up of 3 years. In the group of patients with type B2 fractures, composed of 25 patients, the femoral component was replaced with a revision uncemented stem with cerclage wires or titanium tapes or cables. Osseointegration of the stem was recorded in 24 patients, one female patient died 4 months after the surgery. An excellent result was achieved in 16 patients (64%), a very good result in 4 patients (16%). The remaining 5 patients (20%) failed to meet the minimum follow-up of 3 years. In 8 patients with type B3 trauma, the reimplant of a revision stem was supplemented by spongioplasty, in 2 cases by solid corticocancellous bone grafts with cerclage. In this group osseointegration occurred in all the cases within 6-9 months. The follow-up was affected by the older age of patients and 6 patients died during the follow-up period. The requirement of a follow-up longer than 3 years was met in 2 patients (25%) only and the result was considered very good. In the group of 19 patients with type C fracture, plate osteosynthesis was performed, which was in 12 cases complemented with spongioplasty. Healing occurred within 6 months in 13 patients (72%), within 9 months in 3 patients (17%) and in 2 patients (11%) reoperation was carried out due to fixation failure. One female patient died 16 days after the surgery. An excellent result was achieved in 15 patients (83%), in the remaining three patients the follow-up was shorter than three years due to their death. DISCUSSION Periprosthetic femoral fractures after total hip replacement is a rare but feared complication. Its incidence ranges from 0.1 to 4%. It occurs most frequently 7 to 8 years after the primary implant and 3 to 4 years after the revision of endoprosthesis implantation. The main risk factor is the loosening of stem of endoprosthesis. Another risk factor is osteoporosis. Age, sex and obesity do not constitute significant risk factors. Stem stability and presence of bone defects are the main criteria in favour of surgical treatment. If the stem remains well fixed, the osteosynthesis is opted for, whereas if the stem is loose, its replacement has to be performed. The management of bone defects is an integral part of femoral reconstruction and restoration of endoprosthesis stability. CONCLUSIONS Surgical treatment of periprosthetic fractures, thanks to the introduction of new implants for osteosynthesis and development of new stems for revision endoprostheses, helps achieve ever better results. Of major importance for choosing the treatment method is correct classification of fracture and stem stability. Poor bone quality is a common feature, therefore a perfect mechanical fixation is necessary. The long-term results are affected primarily by the patient s age.

The aim of the study was to analyse the impact of different prognostic factors on the time until the development of contralateral fracture and to determine the incidence of contralateral hip fractures after femoral neck fractures. Patients aged 60 years and over with contralateral hip fracture between 01 Jan 2000 and 31 Dec 2008 were identified among those who suffered their femoral neck fracture in Hungary in 2000. Risk factors as age, sex, comorbidities, type of fracture and surgery, place of living and hospitals providing treatment for primary fracture were analysed by one way ANOVA focusing on the time until the development of contralateral hip fracture. 312 patients met the inclusion criteria. The incidence of contralateral hip fracture after femoral neck fracture ranged between 1.5% and 2.1%, the cumulative incidence was 8.24%. The mean time until the development of contralateral hip fracture was 1159.8 days. The incidence of contralateral hip fracture showed no significant deviation. Significantly shorter time (p = 0.010) was detected until the contralateral hip fracture in older patients with femoral neck fracture. The yearly incidence of contralateral hip fracture showed no significant difference by patients with femoral neck fracture over 60 years. The shorter time until the contralateral hip fracture by the older age groups highlights the need of elaboration of prevention strategies.

The data of patients with intracapsular fractures of the femoral neck surgically treated in the period from 2001 to 2011 were reviewed. Of 1555 patients treated for this fracture, 125 (7%) underwent osteosynthesis. The evaluated group included 115 patients who came for examination at one-year follow-up. There were 59 (52%) women and 56 (48%) men. Dynamic hip screw (DHS) osteosynthesis with an anti-rotation screw was performed in 103 patients and lag-screw osteosynthesis involving three parallel cannulated cancellous screws was employed in 12 patients. The patients were allocated to groups according to the injury-to-surgery interval and to sub-groups on the basis of the Garden classification of femoral fracture stage. In the group of 58 patients treated within 6 h of injury, AVN developed in 10 (17%). When the type of fracture was considered, 4% of the non-displaced fractures and 30% of the displaced fractures developed AVN. The patients with Garden stage I and II (non-displaced) fractures treated within 6 h of injury had a significantly lower risk of AVN development than those with Garden stage III or IV (displaced) fractures. The group treated between 6 and 24 post-injury hours comprised 21 patients, of whom four (19%) had AVN. In non-displaced and displaced fracture sub-groups, 25% of the patients in the former and 16% in the latter had AVN. The stage of displacement had no effect on AVN development. The two groups together (patients treated by 24 h) had a significantly lower AVN incidence than the patients treated after 24 h (p = 0.0025). In this group of 36 patients, 16 had AVN (44%) and the fracture stage made no significant difference (p = 0.6985; nondisplacement sub-group, 41%; displacement sub-group, 55%). The study showed a significantly lower AVN occurrence in the patients surgically treated within 24 h of injury. In the patients treated within 6 h of injury, AVN incidence was significantly lower in the patients with non-displaced fractures, as compared with those who had displaced fractures. This was not true for the two patient groups treated later (6-24 and later than 24 h) in which the differences between AVN development after non-displaced fractures and that after displaced fractures were similar." }, { "id": "pubmed23n0856_16770", "title": "The World Hip Trauma Evaluation Study 3: Hemiarthroplasty Evaluation by Multicentre Investigation - WHITE 3: HEMI - An Abridged Protocol.", "score": 0.009009009009009009, "content": "Approximately half of all hip fractures are displaced intracapsular fractures.

She presented other features resembling AFF: history of bisphosphonate use, prodromal symptoms, no associated trauma, and lateral bowing of the contralateral femur. The fracture showed nonunion after the initial osteosynthesis, and a revision surgery of the arthroplasty and osteosynthesis was performed. Nine months after the surgery, bony union was achieved and she regained the ability to walk. It is supposed that the fracture was influenced by a stress force related to implants and lateral bowing concentrating on the fracture site as a mechanical factor in addition to bisphosphonates as a biological factor.

Briefly, LSCS is a nervous system syndrome that is characterized by neural symptoms in the lower extremities due to tightened cauda equina and spinal nerve root involvement. LSCS international classification consists of: (1) degenerative, (2) congenital developmental, (3) combined, (4) spondylolytic spondylolisthesis, (5) iatrogenic and (6) post traumatic stenosis. Degenerative stenosis-the most common type of LSCS-is caused by disc degeneration, osteoarthritis of the facet joint and hypertrophy of the ligamentum flavum. LSCS may also be the result of intervertebral disc degeneration, protruded intervertebral disc and/or bony spur compress cauda equina and spinal nerve root anteriorally, while degenerated facet joint and hypertrophied the ligamentum flavum compress cauda equina and spinal nerve root posteriorally? Most often, spondylolytic spondylolisthesis occurs at the fourth lumbar vertebrae in middle-aged women. As a result of a slipping forward of the vertebra, cauda equina and spinal nerve roots can be tightened between the edge behind the top of lower vertebra and frontal edge of the lower part of upper lamina. Typical clinical symptoms of LSCS are low back pain, leg pain and intermittent claudication. Low back pain is chronic with secondary radiating pain in the buttock. The leg pain is called \"sciatica\", which tends to appear on the back of thigh, in the lateral aspect of lower leg and calf muscles, and which intensifies when the patient is fatigued. Intermittent claudication is a symptom associated with this syndrome. Often, patients with LSCS find it impossible to walk because of increased numbness and pain in their leg. Many patients report that after squatting for a few minutes they are able to resume walking. LSCS patients may also report dysaesthesia in the perineum area, and may also report urinary dysfunction ranging from extreme urgency to urinary delay. Patients who present with symptoms of LSCS should be seen by an orthopedic surgeon. Correct diagnosis by imaging and clinical examination, with appropriate conservative or operative treatment in a timely fashion should be encouraged in order to prevent irreversible nerve damage." }, { "id": "article-20584_16", "title": "Disc Herniation -- History and Physical -- Physical Examination", "score": 0.011553936494127882, "content": "L5 Nerve - back, radiating into buttock, lateral thigh, lateral calf, and dorsum foot, great toe; sensory loss on the lateral calf, dorsum of the foot, webspace between first and second toe; weakness on hip abduction, knee flexion, foot dorsiflexion, toe extension and flexion, foot inversion and eversion; decreased semitendinosus/semimembranosus reflex.

We report the case of a 50-year-old woman who was referred for treatment of persistent neuropathic pain in the left lower limb after resection of a schwannoma on the left S1 nerve root. The patient's history goes back when she was 27 years old and started to have electric-like pain in her lower left limb upon intercourse. Examination revealed a left ovarian cyst which was surgically removed. Her pain persisted despite taking nonsteroidal anti inflammatory drugs (NSAIDs). Several years later a schwannoma on the left S1 nerve root was detected. The patient had surgical excision of the left S1 nerve root at the plexus along with the schwannoma. Following the surgery, she experienced pain upon sitting and touch, and had a limp in her left leg. She was prescribed NSAIDs, antidepressant and pregabalin. Despite the pharmacological treatment, the patient had persistent mild pain. Upon physical examination, the incision from her previous surgery was 4 cm away from the sacral midline and parallel to S1 and S2. The length of the incision was 3 cm. The patient had severe allodynia upon palpation at the area between S1 and L5 and the visual analog scale (VAS) score increased from 3 to 10. She had severe pain at rest and movement. Her neurologic exam revealed that the left lower extremity motor power showed mild weakness in the leg abduction, foot eversion, plantar and toes flexion, and in the hip extension. The sensory exam showed severe reduction in pinprick and temperature sensation in the lateral aspect of foot, lower leg and dorsolateral thigh and buttocks. Nerve stimulator guided injection was performed at the pain trigger point being 1 cm above the midline of the incision. Upon nerve stimulation the contraction of the gluteal muscle was observed.

The patient had been in good health otherwise until 2000, when she had onset of numbness or tingling of the bilateral lower limbs. On December 3, 2000, she was admitted to a hospital in the vicinity of her home because of the above-mentioned complaints. Neurological examinations revealed progressive paraplegia. Symptoms and signs suggested Guillain-Barré syndrome. Examinations of cerebrospinal fluids revealed cell count of 338/3 (mono 72%, poly 18%) and protein value of 100 mg/dl. Later the patient course deteriorated. On December 15, 2000, she was admitted to Hakujikai Memorial Hospital for the second time. Ten days later, MRI examination showed diffuse swelling of the spinal cord from the cervical (C 3/4) level to the thoracic level. Gd-enhanced T 1-weighted MRI performed 22 days later showed a partially enhanced lesion at the thoracic (Th 5/6) level of the spinal cord. The patient was treated with steroid therapy (methylprednisolone 500 mg/dl). She died of respiratory failure on January 6, 2001. The patient was presented in a neurological CPC. Neurological and imaging findings suggested a transverse myelopathy. However, there were several points in this case that were unusual for a typical transverse myelopathy, such as total sensory loss below spinal segments of thoracic level (Th 5) and motor weakness of the upper limbs of upper segment of the same level. A clinical neurologist concluded that the patient had subacute transverse myelopathy with fused multiple pathy pathologic lesions. We discussed whether this case was a transverse myelopathy or multiple sclerosis. Post mortem examination revealed acute necrotic myelopathy affecting the spinal cord from the second cervical to the tenth thoracic vertebrae, with conspicuous infiltration of CD 68-positive macrophages involving both gray and white matter, partially necrotic associated with scattered UCHL-1 dominants lymphocytic infiltration of T cells around vessels. There were relatively older lesions with demyelinating features in the spinal roots that were particularly dominant in the anterior roots. No demyelinated plaques in the optic chiasm, tracts and nerves, or in the cerebero-cerebellar white matter were found.

For example, slowing of the NCV usually indicates there is damage to the myelin. Another example, slowing across the wrist for the motor and sensory latencies of the median nerve indicates focal compression of the median nerve at the wrist, called carpal tunnel syndrome.

On February 29, 1996, she developed a weakness in the right limbs. Subsequently, she suffered numbness and clumsiness in the left limbs, even though muscle strength of the left limbs was preserved. Seventeen days later, she was referred to our hospital. A T2-weighted MRI after admission demonstrated high signal intensities in the left dorsal column and the right antero-lateral part of the cervical cord at the C1 to C3 vertebral level. Under the diagnosis of probable multiple sclerosis, steroid pulse therapy was applied twice and she gradually regained muscle strength in the right limbs and sensation in the left limbs. One month later, elemental sensations such as pain, touch, temperature, vibration, and position, as well as discriminative sensations such as localization sensation, two-point discrimination, barognosis, pinch-press discrimination, and graphesthesia in the left limbs returned to normal. However, her left hand remained clumsy, especially when she tried to manipulate objects. She also showed a great difficulty in sustaining a constant level of pinching force by the left thumb and index finger, and in localizing her right thumb placed in space with the left hand with her eyes closed. She stated herself that she could not sense at all how her left hand and fingers were moving. Somatosensory evoked potentials recorded from the right scalp showed that the NI was poorly organized and the patency of subsequent peaks was delayed. Transcranial magnetic stimulation revealed that the pyramidal tract from the right motor cortex to the left cervical cord was functionally intact. These observations lead us to conclude as follows: (1) the patient's left hand clumsiness is probably due to the disturbance of kinesthesia, which is crucial to activate temporo-spatial patterns of complex hand and finger movements as well as to maintain long sequences of simple motor execution without vision; and (2) kinesthesia is a specific sensation that is presumably conveyed by the dorsal columns and could be selectively affected by a cervical cord lesion." }, { "id": "wiki20220301en510_541", "title": "Distal hereditary motor neuropathy type V", "score": 0.009259259259259259, "content": "Distal hereditary motor neuropathy type V is a particular type of neuropathic disorder.

Proportion of prevalence of particular types of clinical courses is not precisely estimated, but it appears that at least a half of the cases is of non-progressive type. Non-operative treatment of the condition may be effective in those particular cases, without risk of the development of severe neurological complications as a consequence of impairment of the median nerve. The evidence form analysed studies shows that in carpal tunnel syndrome, the clinical symptoms and signs and nerve conduction disturbances have different natural histories. Clinical features are subjected to greater temporal fluctuations than electrophysiological findings, and they frequently do not correlate one with another. There is not common opinion about efficacy of intervention in extreme carpal tunnel syndrome, characterised by severe conduction disturbances in electrophysiological tests and fixed neurological deficits, however surgical decompression of the carpal tunnel appears to be more promising than decline of the treatment.

In the present study we report the clinical, electrophysiological and MRI features of a group of Italian patients, with review of the literature. Moreover we propose an optimized MRI protocol for patients with suspected or diagnosed HD in order to make an early diagnosis and a standardized follow up. Eight patients with clinical suspicion of Hirayama disease underwent evaluation between January 2007 and November 2013. All patients underwent standard nerve conduction studies (NCS), electromyography (EMG) and motor/sensory evoked potentials (MEP/SEP). Cervical spine MRI studies were conducted with a 1.5 Tesla MRI scanner in neutral and flexion position, including sagittal T1-weighted sequences and sagittal and axial T2-weighted sequences. The following diagnostic features were evaluated: abnormal cervical curvature, localized cervical cord atrophy in the lower tract (C4-C7), presence of cord flattening (CF), intramedullary signal hyperintensity on T2 weighted sequences, anterior shifting of the posterior wall of the cervical dural sac (ASD) and presence of flow voids (EFV) in the posterior epidural space during flexion. All patients complained of weakness in hand muscles as initial symptoms, associated with hand tremor in three of them and abnormal sweating of the hand palm in two of them. No sensory deficits and weakness at lower limbs were reported by any patients. Distal deep tendon reflexes at upper limbs were absent in all patients with the absence of the right tricipital reflex in one of them. Deep tendon reflexes at lower limbs were normal and no signs of pyramidal tract involvement were present. The clinical involvement at onset was unilateral in six patients (three left-sided and three right-sided) and bilateral asymmetric in two of them, with the right side more affected. With the progression of the disease all patients but one experienced weakness and wasting of hand muscles and forearm bilaterally, but still asymmetric. The duration of the progression phase of the disease ranged from eight months to three years. In all patients, NCS and EMG findings were consistent with a spinal metameric disorder involving the C7-T1 myotomes bilaterally; sensory conduction and electrophysiologic features at lower limbs were normal. MEP and SEP were normal and we did not observe the disappearance of the spinal potential during the neck flexion in any of the patients. MRI is the best diagnostic tool in the diagnosis of HD; it can confirm clinical diagnosis and exclude other conditions responsible for the neurological deficits leading to a correct patient management and therapy, limiting arm impairment. On MRI all patients had loss of the normal cervical lordosis (100%). Five patients had loss of attachment of posterior dural sac and anterior dural shift on flexion MRI with presence of flow voids from venous plexus congestion (62.5%); three patients had no anterior dislocation of the dural sac and no epidural vein congestion. Two patients showed localized cord atrophy, one at C5-C6 and the other at C6-C7 level (25%). Three patients had T2 intramedullary hyperintensities (37.5%) and cord flattening (CF) was present in 5 patients of 8 (62.5%). HD is a rare entity and a self-limited condition, but it has to be early differentiated from other diseases that may determine myelopathy and amyotrophy to establish a correct therapy and limit arm impairment. MRI is very important to confirm the clinical suspect of HD and a standardized MRI protocol using axial and sagittal images in both neutral and flexing position is needed, in order to diagnose and follow up affected patients." }, { "id": "pubmed23n0918_10443", "title": "Characteristics of nerve conduction studies in carpal tunnel syndrome.", "score": 0.00909090909090909, "content": "Numerous nerve conduction tests are used for the electrodiagnosis of carpal tunnel syndrome (CTS), with a wide range of sensitivity and specificity reported for each test in clinical studies.

On neurological examination, a slight to moderate degree of muscle weakness with slight atrophy was observed in the bilateral intrinsic hand muscles. A severe degree of muscle weakness with moderate atrophy was observed in tibialis anterior, gastrocnemius and soleus muscles. Muscle stretch reflexes were decreased in the upper limbs and absent in the lower limbs, without pathologic reflexes. She had a steppage gait. Vibratory sensation was slightly decreased in the hands and moderately decreased in the feet. Touch, pain and temperature sensations were also moderately decreased only in the feet. On laboratory examination, glycosuria (5.6g/dl) was noted. Fasting blood sugar was 226mg/dl with an elevated hemoglobin A1C level (12.7%). The right median motor and sensory nerve conduction velocities were 14.8 and 20.3 m/sec, respectively, with a markedly prolonged distal latency. No muscle action potential was obtained from stimulation of the right tibial nerve. Also, no nerve action potential was elicited from stimulation of the right sural nerve. A fascicular biopsy of the right sural nerve revealed the presence of both demyelinated and remyelinated axons, and an onion-bulb formation with a marked decrease in the density of the myelinated fibers.

Based on the family history, an uncle on the mother's side of the proband, the proband's grandmother and a younger daughter of a proband's brother were considered to be affected. The uncle and grandmother had diabetes mellitus. Therefore, we concluded that this family had HMSN type I with autosomal dominant inheritance. In the studies on fluorescence in situ hybridization, and restriction fragment length polymorphism of the genomic DNA of the proband, a DNA duplication in the 17p11.2-12 region was not observed. However, the direct sequencing analysis of DNA fragments from genomic DNA encoding the Po gene of the proband revealed a substitution of histidine for arginine at the codon 98 in the extramembranous domain of Po. She was heterozygous for the mutant allele and normal allele. Alterations in the tertiary structure of the extramembranous domain of Po may result in an impairment of the peripheral myelin compaction. This is the second Japanese family with the same mutation (Arg98--&gt;His) of myelin Po as reported previously by us, and this type of case is rare in the literature.

A MEDLINE search was performed through the clinical queries service of PubMed searching for the following terms: nerve-conduction, Tinel's test, Phalen's test, tendon reflex, two-point discrimination test, abduction external rotation test, and Spurling test. Retrieved articles were discussed both in relation to the test accuracy and the validity aspects of the tests. The evidence in support of the view that neurological tests can accurately distinguish between subjects with and without neuropathy specifically addressing hand-arm vibration syndrome was sparse. The initial number of diagnostic hypotheses could be reduced by progressively ruling out diseases based on negative results of highly sensitive tests. As the possible diagnostic alternatives become fewer, the use of positive results from highly specific tests are more effective. The information value of the various diagnostic tests is determined by the change in pre-test to post-test probability of target disorder, which depends on the prevalence of the disorder and the likelihood ratios of the tests.

However, she developed a recurrence about 5 weeks later, with more extensive and coalescent skin lesions (Figure 2). Additionally, there was a new onset of alopecia and pain in the small joints of the hands as well as both knees and ankles. At this time, the patient's ESR had gone up to 112 mm/h and she had developed significant proteinuria, with a protein creatinine ratio of 1.3 g/g (reference &lt;0.5 g/g). Her antinuclear antibody (ANA) titer was high (1:320) with a speckled pattern. Anti-Smith antibody was also positive. A renal biopsy was declined. A tentative diagnosis of Rowell syndrome was made. The patient was started on high-dose steroids and hydroxychloroquine 200 mg twice daily. Subsequent care included the use of mycophenolate mofetil 1 g twice daily for 6 months. This was then changed to azathioprine at 50 mg twice daily. Follow-up after 6 months showed sustained clearance of skin lesions, resolution of fever and joint pains, as well as improvement in the renal profile, with a urine protein-creatinine ratio of 0.77 g/g. The presence of systemic lupus erythematosus, EM-like lesions, and a speckled pattern of antinuclear antibody in our patient fulfils the revised diagnostic criteria for RS put forward by Zeitouni et al. at the turn of the twenty-first century (2). Considering the rarity of EM-like lesions in SLE and the possibility of constitutional symptoms in EM, a diagnosis of RS may be readily overlooked in patients like the one described, whose major cutaneous manifestation of severe active SLE was EM-like lesions. In contrast to classic EM, where skin lesions are concentrated in the extremities, a predominant truncal distribution of EM-like lesions as found in our patient may favor a clinical consideration of RS (3). However, some authors have challenged the existence of Rowell syndrome as a distinct clinical laboratory entity. Arguments put forward in this regard include the fact that none of the immunological markers that have been described in RS are specific to any disorder. Additionally, the annular polycyclic dermatosis seen in sub-acute cutaneous lupus erythematosus (SCLE) can be difficult to clinically and histologically differentiate from EM (4,5). Patients with SLE also have a higher likelihood of developing adverse drug reactions (6). The inherent complexity of SLE may make for delayed and oftentimes difficult diagnosis, especially in a country where immunologic tests are expensive and rheumatologists are scarce. When patients do occasionally present with recurrences of skin lesions in the spectrum of EM, Steven-Johnson syndrome, and toxic epidermal necrolysis in the absence of a definite inciting agent, undiagnosed lupus may indeed be present in some of these individuals and should be considered in the differential diagnosis. In conclusion, while it is very rare, SLE may present first with recurrent episodes of EM-like rash. Despite the various possibilities which underlie their association, prompt identification and treatment of SLE in patients presenting with EM is important to prevent death or irreversible organ damage." }, { "id": "pubmed23n1115_3216", "title": "[Multicentric reticulohistiocytosis: A case report].", "score": 0.015763076188201577, "content": "A 65-year-old woman developed erythema, papules and nodules over the body.

These findings were diagnostic evidences of multicentric reticulohistiocytosis (MRH). The patient received high-dose of glucocorticoids combinated with immunosuppressive agents, and achieved a satisfactory effect. MRH was a rare multisystem disease characterized by papulonodular mucocutaneous and destructive arthritis, and its pathogeny was not yet completely understood. The typical lesions of MRH were hard papules or nodules that usually occured on the hands, face and arms. Classic coral bead appearance from periungual cutaneous nodules that were characteristic of MRH. MRH was an inflammatory joint disease, affecting almost all the appendicular joints and characterized by joint multiple, symmetrical, destructive, progressive disability. Joints destruction of the distal interphalangeal joints was a unique feature of MRH. In addition to skin and joints, it could also involve other systems. There were no diagnostic laboratory markers for MRH. Laboratory examinations had often been found to be non-specific. Imageological examination mainly showed bone and joint destruction. Skin biopsy was the best test to diagnose MRH, the typical histopathological findings included an infiltrate with histiocytes and multinucleated giant cells with a ground-glass appearing in eosinophilic cytoplasm, and the immunohistochemical stain was positive for CD68. The diagnosis was typically made based on the clinical presentation, supportive radiographic findings and skin biopsy. MRH was easily possible to mistake for other more common autoimmune conditions, such as rheumatoid arthritis, psoriatic arthritis, osteoarthritis, and dermatomyositis, but the distinctive clinical, radiographic, and histologic features could aid in differentiating these diseases. MRH could mimic other rheumatic diseases, besides, it could also coexist with cancer or other autoimmune disorders. There was no standardized treatment for MRH. However, Nonsteroidal anti-inflammatory drugs, glucocorticoid, Immunosuppressant, biologic medications, and bisphosphonates had been used with varying degrees of curative effect. Treatment with glucocorticoid combined with immunosuppressants were effective for rash and arthritis, early use of them should be strongly considered, and refractory cases could be treated with biological agents. By reporting a MRH case and reviewing literature, this paper aims to help the clinicians improve the understanding of this rare disease, and suggests that when one diagnosis cannot explain the whole picture of the disease, and further evidence should be sought to confirm the diagnosis." }, { "id": "pubmed23n1151_11646", "title": "[Lack of therapeutic response: Is it really a rheumatoid Arthritis?]", "score": 0.014662894860914663, "content": "A 78-year-old female patient was referred to our hospital with treatment-resistant seronegative anti-citrullinated protein antibodies (ACPA)-negative rheumatoid arthritis.

It was initially reported by Rowell (1) in 1963 and its existence as a separate clinical entity is currently under debate (2,3). A few cases may have been induced by drugs such as systemic antimycotics, antibiotics, anticonvulsants, and more recently proton pump inhibitors (PPIs). CASE REPORT We present the case of a 67-year-old woman with subacute cutaneous lupus erythematosus (SCLE) and EM-like lesions who fulfilled all the criteria for Rowell's syndrome. The patient had lupus arthritis for two years and was treated with oral methylprednisolone 8 mg/day and hydroxychloroquine 200 mg/day. She started receiving 20 mg of omeprazole daily for gastroprotection. The patient also had arterial hypertension with no current treatment, osteoporosis, and an L1 vertebral fracture. The dermatological examination revealed multiple erythematous infiltrated plaques involving mainly the sun-exposed areas (neck, chest, upper back, and shoulders). Cutaneous lesions had an annular or target pattern and a tendency to form hemorrhagic crusts and scales at the margins (Figure 1, A). The mucous membranes were unaffected. Histological examination (hematoxylin and eosin ×200) found epidermal atrophy, vacuolar degeneration of the basal layer, and sparse perivascular lymphocytic infiltrate in the dermis - features corresponding to lupus erythematosus (Figure 2, A). Single eosinophilic necrotic keratinocytes characteristic for erythema multiforme were observed in the epidermis (Figure 2, B). Direct immunofluorescence (IF) from lesional skin showed granular deposits of C3 on the dermo-epidermal junction. Lupus band test from sun-protected, nonlesional skin was negative. On indirect IF a speckled pattern antinuclear antibodies (ANA) with &gt;1:1280 titers were detected. Anti-Ro (&gt;200 U/mL) and anti-La (&gt;200 U/mL) antibodies were also positive. The blood cell count and differential analysis were within reference ranges. The 24-hour urine protein test showed a non-significant proteinuria - 0.36 g/24h. Photo-testing was impossible considering the extent of the skin lesions. The therapeutic approach consisted of increasing the hydroxychloroquine dose to 400 mg/day, substituting PPI with famotidine 20 mg/day p.o. and ceftriaxone 2 g/day for the superinfection with Ps. aeruginosa, which led to a clinical improvement (Figure 1, B). The methylprednisolone dose remained unchanged due to already existing severe adverse effects. DISCUSSION The diagnosis was based on Zeitouni et al.'s classification (4). The three main criteria are as follows: lupus erythematosus, EM-like lesions, and speckled pattern of ANA. Our patient met all three major and one minor criteria, namely the presence of anti-Ro and anti-La antibodies. As for the other minor criteria, RF was negative and no chilblains were found. Although there was a continuous time lapse (more than 1 year) between the initiation of omeprazole intake and the diagnosis of Rowell's syndrome, we suggest that the connection is probable. For instance, the latency differs depending on the incriminated medication in drug induced SCLE. Longer periods are reported for diuretics and calcium blockers, while the time interval is shorter for chemotherapeutic drugs and antimycotics (5). Our suspicions were further confirmed by the fact that the lesions improved promptly within a month after discontinuation of omeprazole and doubling the dose of hydroxychloroquine. PPIs are reported to be a major cause of drug-induced SCLE (6,7). According to Laurinaviciene et al., the most common drugs involved are PPIs, thiazide diuretics, antifungals, chemotherapeutics, statins, and antiepileptics (6). However, very few cases of Rowell's syndrome are found to be drug-related. The culprit drugs include: oral terbinafine (8,9), norfloxacin (10), sodium valproate (11) and esomeprazole (12) (Table 1). CONCLUSION Despite the common clinical and immunological features shared between SCLE, drug-induced SCLE and EM, Rowell's syndrome seems to be a separate entity rather than a coincidental association. Finally, according to our knowledge this case would be the second of Rowell's syndrome due to PPIs." }, { "id": "pubmed23n1014_1022", "title": "A Rare Case of Adult-onset Still's Disease with Anti-Ro Antibody Positive.", "score": 0.011121856866537718, "content": "Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disorder.

It may be occasionally accompanied with other eosinophilic or autoimmune dysfunctions (1,2). Lack of international diagnostic criteria and treatment consensus may lead to diagnostic and therapeutic difficulties. The 61-year-old man with no significant personal or family pathological history was admitted to the Dermatology Department presenting persistent induration for several months as well as erythema and pain of the shins that gradually extended to thighs and forearms, with limited mobility of peripheral joints. (Figure 1) Additional tests showed leukocytosis with 16% eosinophilia, elevated CRP, and hypergammaglobulinemia. Borrelia burgdorferi antibodies (classes IgM and IgG) were negative twice. A biopsy that included deep fascia was taken for histopathological examination. Antinuclear antibody screening was negative, but the direct immunofluorescence showed complexes in the dermo-epidermal junction and around the vessels. The diagnostics conducted toward malignant process showed no disturbing abnormalities (i.e. tumor markers in serum, chest, and abdomen computed tomography imaging, panendoscopy). The treatment was carried out with cephalosporin and nonsteroidal anti-inflammatory drugs (NSAIDs). The condition did not improve much but was stable. Histopathological results were indicative of eosinophilic fasciitis with fibrous thickening of deep fascia and perivascular infiltrations of plasma cells and lymphocytes; oral prednisone was initiated and the condition begin to improve. After 12 weeks, we observed disease progression with fever and very hard and cyanic skin lesions, which presented as an orange peel with linear furrows over the superficial venous vessels (Figure 2). The lesions extended to the trunk and caused troubles in moving. A complex rehabilitative intervention was started to minimize the inflammatory fascial restrictions. The prednisolone dose was increased, and oral methotrexate was added. After two weeks, the patient suffered from abdominal pain and periodic bleeding diarrhea. Methotrexate was suspected of inducing gastrointestinal adverse effects, and antipyretic NSAIDs were completely withdrawn. Colonoscopy showed features of mucosal edema with erythema, and histopathological examination revealed eosinophilic colitis. The patient was referred to a gastroenterologist, and methotrexate was ceased and switched to azathioprine. In summary, the consensus therapy of the rheumatologist, dermatologist, and gastroenterologist consisted of prednisolone and azathioprine. As of this writing, the patient's condition is gradually improving. The most characteristic symptoms of eosinophilic fasciitis is sudden onset with induration, sclerosis, and pain of the skin, with subcutaneous tissue and fascia usually appearing on the upper and lower limbs (3,4). The skin surface forms a characteristic orange peel appearance. The \"groove\" sign refers to the linear furrows over the superficial vessels of the extremities (1). Typical abnormalities are eosinophilia, elevated CRP, and hypergammaglobulinemia. The presence of eosinophilia is the most characteristic feature, occurring in 60-93% cases, but it is not necessary for diagnosis (1,5). Antinuclear antibodies are commonly absent with positive lesional direct immunofluorescence (6). If antinuclear antibodies are positive, it is recommended to broaden the diagnostic process to include other connective tissue diseases. Eosinophilia must be differentiated from hematological disorders and paraneoplastic syndrome. (4,6). Eosinophilic colitis is an eosinophilic gastrointestinal disease (EGID). It is the least frequent manifestation of EGID. It may be associated with connective tissue diseases, mostly systemic sclerosis - to our knowledge, there is no information in the literature about coexisting eosinophilic fasciitis. (7,8). The case described herein demonstrated that such a connection may occur. In treatment, it is important to prevent the patient from contractures and to maintain joint mobility by appropriate physiotherapy (2,9). The fascia forms a functional integral and continuous structure. Inflammation of one part of it changes the elasticity of the whole and produces fascial restrictions with movement limitation and pain. The fascia is profusely innervated, which favors constriction as a result of inflammation, and is also poorly vascularized which disrupts its regeneration (9,10). Myofascial techniques improve fascia elasticity by breaking up the tissue adhesions caused by inflammation (11). Eosinophilic fasciitis is a rare clinical entity, but knowing the possible clinical symptoms and laboratory abnormalities should help in taking the appropriate diagnostic path. It is important to treat the patient with attention to all concomitant diseases in consultation with different specialists." }, { "id": "InternalMed_Harrison_25234", "title": "InternalMed_Harrison", "score": 0.010611237661351556, "content": "Several developments during the past two decades have changed the therapeutic landscape in RA.

The clinical features of early- and extended-stage MPA were studied in detail and the premorbid background and possible precipitating factors were analyzed in 70 patients with MPA and the proven hyperproduction of antineutrophil cytoplasmic antibodies (anti-proteinase-3 (anti-PR3) antibodies in 55% and anti-myeloperoxidase (anti-MPO) antibodies in 45%) who had been followed up for more than a year. There is evidence for the nosological unity of the two immunological types of MPA associated with anti-PR-3 or anti-MPO antibodies. MPA has been demonstrated to be an aggressive, polysyndromic disease prone to recurrences (52%), the typical manifestation of which is glomerulonephritis (94%) that is rapidly progressive in every four cases and accompanied by hemorrhagic alveolitis (69%) and involvement of other organs. ENT organs and lungs have been noted to be commonly involved in early-stage MPA, which was observed in 61% of the patients in the premorbid period, and to become the first manifestation of MPA (63%) concurrent with body temperature rises (64%), arthralgia or arthritis (41%). Respiratory tract involvement in MPA may be asymptomatic. Anti-PR-3-associated MPA may manifest itself more aggressively and in the first 2 years it is characterized by a poorer prognosis than of anti-MPO-associated MPA (survival rates, 82 and 94%, respectively; p = 0.04). With time, the differences were levelled off; recurrences in the patients with anti-PR-3 and anti-MPO develop equally frequently and proceed showing the similar clinical picture; the survival curves converge by age 3. Anti-MPO-associated MPA is characterized by the highest rate of lung involvement in the clinical phase of the disease (61%) and by a propensity to develop hemorrhagic alveolitis, diffuse interstitial (22%) or circumscribed pulmonary fibrosis in the outcome. CONCLUSION. The findings emphasize how important to diagnose MPA early and to prescribe long-term active treatment using the entire current arsenal of medications as soon as possible until severe injury to organs and systems develops. To specify regularities in the development of MPA may be of value for the better diagnosis of the disease and the further elaboration of optimal treatment policy." }, { "id": "wiki20220301en243_17832", "title": "Gero Hütter", "score": 0.00909090909090909, "content": "to express wildtype CCR5 (because they hadn't been replaced yet from bone marrow precursors), also had no detectable virus.

Histologically, the main features are histiocytes laminated between collagen fibres, sometimes organized in rosettes comprising tiny granulomas surrounding fibres of homogeneous aspect. Four patients fitting this description were investigated. Cutaneous lesions displayed various patterns: cord-like lesions (one patient), brown plaques on the flanks edged with papules (one patient), grossly annular violaceous plaques on the back (one patient), and infiltrated plaques on the palms and thighs (one patient). Joint symptoms were present in all cases (one seropositive rheumatoid arthritis and one seronegative rheumatoid arthritis, both already known; acute rheumatoid arthritis in two cases). The histological pattern was quite similar in all cases, with laminated histiocytes in palisading layers mixed with swollen collagen fibres; \"rosette\" figures were present in two cases. Autoimmune response was seen with antinuclear antibodies (two cases) and/or rheumatoid factor (two cases).

Pathophysiological mechanisms and nosological borders are debatable and authors consider this condition as either an autonomous disease or else a mere subset of vasculitis with palisading granulomas in collagen vascular disorders, despite the rarity of authentic vasculitis. A setting of autoimmunity is frequently present. Furthermore, a fairly similar histological pattern is sometimes seen in some lesions forming a subset of cutaneous side-effects of drugs.

Since 1954, more than 300 observations were published including mediastino-pulmonary forms (about 60 p. 100 of the cases) intra-abdominal forms (15 p. 100 of the cases) and superficial forms which represent 25 p. 100 of the cases and associate superficial ganglionic, intra-muscular and subcutaneous localizations. The authors report the observation of a 44-year-old negro who had a subcutaneous tumefaction of the left elbow which appeared recently without a functional sign nor a biological change. The histological findings allowed the diagnosis of Castleman's pseudolymphoma in a hyalino-vascular form or Flendrig's type II. The evolution was marked a few weeks later by a local recurrence of which a second surgery has secured the recovery. The detailed study of the 76 cases of Castleman's superficial pseudo-tumours published in the literature allows us to recall the features of this disease which affects especially the young adult without prevalence of sex at about 25 years old. The circumstances of discovery are univocal, isolated palpable subcutaneous tumefaction in most of the cases. The localizations are distributed by decreasing incidence as following: latero-cervical, axillary, sus-clavicular, inguinal, vulvar, abdominal wall, shoulder, arm, forearm with a few bifocal forms. The histological aspect associated a predominant lymphoid population and vessels with fibro-hyalinous wall which morphological variations have permitted to individualize three forms: a plasmocytic form or Flendrig's type I which should be a stage of beginning often associated with hematological changes, a hyalino-vascular form or Flendrig's type II more frequent and a mixed form or intermediary type. The immunofluorescence, histo-enzymology and immunohistochemistry studies reveal a changeable polyclonal plasmocytosis and a predominance of T-suppressors in the lymphocytic population. The histological differential diagnosis of the superficial forms of the Castleman's pseudolymphoma is rarely set with certain lymphoma in case of ganglionic localization. On the other hand isolated subcutaneous localizations must be distinguished of the Kimura's disease and of the angiolymphoid hyperplasia with eosinophils where the vessels have a different morphology.

Additionally, COPD places a tremendous burden on the health care system, with estimated annual costs of US 24 billion dollars in 2000, and it is generally expected that costs will continue to rise as more individuals are diagnosed. COPD was responsible for approximately 8 million physician outpatient visits, 1.5 million emergency department visits and 726,000 hospitalizations, also in the year 2000. The objective of this article is to review current, pertinent clinical issues in the management of patients with COPD, with estimates of their relative utility and efficacy. COPD is a disease characterized by airflow limitation that is not fully reversible. Patients with COPD may frequently experience symptoms of chronic cough with sputum production, dyspnea, and reduced exercise capacity. They may frequently experience exacerbations characterized by increased symptoms that often require medical intervention. The diagnosis of COPD is usually fairly straightforward and made in a cigarette smoker, with the aforementioned symptoms and airflow obstruction measured by spirometry. Spirometry should be performed in all patients in whom COPD is suspected, as it provides useful prognostic information and may be used to stage the disease. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) has provided evidenced-based management guidelines for COPD. GOLD guidelines advocate staging COPD by spirometry and make specific treatment recommendations based on COPD stage. The most important risk factor for the development of COPD is cigarette smoking, and smoking cessation has been shown to reduce all-cause mortality and to alter the natural history of COPD. Smoking cessation strategies that employ both counseling and medications like buproprion and nicotine replacement are most effective, but relapse rates remain high. It has not been shown that medications like bronchodilators or inhaled steroids change the natural history of COPD, nor do they reduce mortality, but they can affect other important outcomes. Long-acting bronchodilators, including beta- 2-adrenergic agonists such as salmeterol and formoterol, and the anticholinergic agent tiotropium, improve lung function and exercise tolerance, reduce symptoms, and modestly reduce exacerbation rates. Long-acting bronchodilators are indicated for all COPD patients with chronic symptoms. Short-acting bronchodilators are indicated for rescue when acute symptoms occur. Inhaled corticosteroids minimally improve lung function, but, importantly, reduce exacerbation rates and are indicated in severe COPD or when exacerbations are frequent. Continuous oxygen therapy has been shown to reduce mortality when severe hypoxemia is present and can improve quality of life when moderate hypoxia is present. Finally, well-designed, multidisciplinary disease management programs and pulmonary rehabilitation can improve important disease outcomes in a cost-effective manner. COPD is a common, preventable disease that affects a significant number of people. It may be managed by utilizing various readily available medical therapies, as well as other nonpharmacologic interventions, such as pulmonary rehabilitation. Proper coordination of care is important in this disease, and efforts should be focused on improving quality of life and reduction of symptoms." }, { "id": "pubmed23n0801_9963", "title": "The clinical and integrated management of COPD.

However, the benefit of inhaled glucocorticoids in addition to two long-acting bronchodilators has not been fully explored. In this 12-month, double-blind, parallel-group study, 2485 patients with a history of exacerbation of COPD received triple therapy consisting of tiotropium (at a dose of 18 μg once daily), salmeterol (50 μg twice daily), and the inhaled glucocorticoid fluticasone propionate (500 μg twice daily) during a 6-week run-in period. Patients were then randomly assigned to continued triple therapy or withdrawal of fluticasone in three steps over a 12-week period. The primary end point was the time to the first moderate or severe COPD exacerbation. Spirometric findings, health status, and dyspnea were also monitored. As compared with continued glucocorticoid use, glucocorticoid withdrawal met the prespecified noninferiority criterion of 1.20 for the upper limit of the 95% confidence interval (CI) with respect to the first moderate or severe COPD exacerbation (hazard ratio, 1.06; 95% CI, 0.94 to 1.19).

The symptoms that worsen are not specific to COPD and differential diagnoses need to be considered. Acute exacerbations are typically treated by increasing the use of short-acting bronchodilators including a combination of a short-acting inhaled beta agonist and short-acting anticholinergic. These medications can be given either via a metered-dose inhaler with a spacer or via a nebulizer, with both appearing to be equally effective. Nebulization may be easier for those who are more unwell. Oxygen supplementation can be useful. Excessive oxygen; however, can result in increased levels and a decreased level of consciousness.

Exacerbations stud the course of COPD. Their frequency is variable, averaging 1-2 per year. Their frequency generally increases with COPD severity. Exacerbations impair patients' quality of life and aggravate disease prognosis by accelerating the decline in FEV1, the primary indicator of respiratory function. The most frequent causes of exacerbations are viral and bacterial respiratory infections and pollution. No cause is identified for nearly one third of all exacerbations. Most exacerbations can be treated at home, if a careful search for signs of clinical severity is negative. Treatment combines inhaled bronchodilator agents (beta-2 agonists, combined if necessary with anticholinergics) and oral corticosteroid therapy (prednisone: 0.5 mg/kg/d for 1 week) when the COPD is severe or signs of severity accompany the exacerbation. Antibiotic therapy is justified when the sputum appears purulent. Severe exacerbation may require oxygen therapy in cases of severe hypoxemia (PaO(2)&lt;60 mm Hg) or mechanically assisted ventilation, essentially by noninvasive ventilation in cases of respiratory acidosis (pH&lt;7.35). Noninvasive ventilation improves dyspnea and respiratory acidosis, diminishes respiratory frequency, intubation, duration of hospitalization, nosocomial infections, and mortality.

Patients with impaired level of consciousness, acute confusion, acute changes on radiography, or an arterial pH of &lt;7.35 or with other serious medical or social reasons for admission were excluded. Patients randomised to home support were discharged with an appropriate treatment package (antibiotics, corticosteroids, nebulised bronchodilators and, if necessary, home oxygen).

Parallel observations were made on patients allocated to normal hospital admission up to the point of discharge. Patients in both groups were assessed at home eight weeks after the initial assessment. Among weekday patients 353 (50%) were considered obligatory admissions, 140 (19%) were admitted because of co-morbidity, 17 (2%) because of poor social circumstances, and 24 (3%) did not consent to the trial.

A review of its use as maintenance therapy in patients with COPD.", "score": 0.009523809523809525, "content": "Tiotropium bromide (Spiriva) is a long-acting anticholinergic bronchodilator that maintains bronchodilation for at least 24 hours, allowing once-daily administration. The active moiety is the tiotropium cation (tiotropium); tiotropium bromide 22.5 micrograms is equivalent to 18 micrograms of tiotropium cation. Greater improvements in lung function from baseline (primary endpoint mean trough FEV(1)) were observed with inhaled tiotropium 18 micrograms once daily than with placebo in 6-month and 1-year randomized, double-blind trials in patients with COPD. Tiotropium improved lung function (trough FEV(1) response) more effectively than ipratropium bromide (ipratropium) 40 micrograms four times daily in 1-year clinical trials, and was at least as effective as salmeterol 50 micrograms 12-hourly in 6-month trials. Preliminary data suggest that tiotropium alone or in combination with once-daily formoterol has a greater bronchodilator effect than twice-daily formoterol in patients with COPD. Improvements in patients' perception of health-related quality of life (HR-QOL) or dyspnea were greater with tiotropium than with placebo or ipratropium, and were similar to those with salmeterol. Reductions in the frequency and severity of acute exacerbations and in the use of rescue medication were also greater with tiotropium than with ipratropium or placebo. There was no evidence of tachyphylaxis with tiotropium during 1-year clinical trials. Inhaled tiotropium was generally well tolerated in clinical trials. Apart from dry mouth, the type and incidence of adverse events with tiotropium were similar to those with ipratropium, salmeterol or placebo in patients with COPD. In conclusion, inhaled tiotropium 18 micrograms once daily improved lung function, dyspnea, and HR-QOL, and decreased the incidence of acute COPD exacerbations and the use of rescue medication relative to placebo or ipratropium in clinical trials in patients with COPD. Tiotropium was at least as effective as salmeterol in terms of bronchodilator efficacy and improvements in dyspnea or HR-QOL. With the exception of dry mouth, the tolerability profile of tiotropium was similar to that with placebo, ipratropium, or salmeterol. Consequently, inhaled tiotropium is likely to be a valuable option for first-line, long-term maintenance therapy in the management of bronchoconstriction in patients with symptomatic COPD. Tiotropium bromide has a quaternary ammonium structure and acts as an anticholinergic bronchodilator; the active moiety is the tiotropium cation (tiotropium). A 22.5 micrograms dose of tiotropium bromide provides 18 micrograms of tiotropium. Orally inhaled tiotropium bromide antagonizes the muscarinic M(1), M(2), and M(3) receptors located in airway smooth muscle, reversing vagally mediated bronchoconstriction. Receptor binding assays and in vitro tests indicate that tiotropium bromide is kinetically selective for M(1) and M(3) receptors over the M(2) receptor, unlike ipratropium bromide, which is nonselective. Animal and in vitro studies showed that tiotropium bromide was more potent ( approximate, equals 20-fold) than ipratropium bromide in displacing [(3)H]N-methylscopolamine (NMS) from muscarinic receptors, and had a more sustained protective effect (&gt;70% inhibition) against NMS binding. Tiotropium bromide was a more potent inhibitor of bronchial contraction than atropine ( approximate, equals 23-fold), and had a slower onset and markedly longer duration of action than atropine or an equipotent dose of ipratropium bromide. Aerosol particle penetration is improved with tiotropium, without delaying mucus clearance from the lungs. Tiotropium 4.5-36 micrograms once daily for 4 weeks increased mean trough and average FEV(1) and FVC and mean PEFR values from baseline compared with placebo, with no evidence of tachyphylaxis. Improvements in trough FEV(1) from baseline with tiotropium 4.5-36 micrograms were not dose dependent. Based on a lack of dose response, the optimal once-daily tiotropium dosage is 18 micrograms. Steady-state trough FEV(1) values are achieved within 48 hours of commencing tiotrochodilation (for &gt;/=24 hours) and an attenuation of the nocturnal decline in FEV(1) that were unaffected by timing of the daily tiotropium dose were seen in randomized, double-blind, placebo-controlled studies in patients with stable COPD. The drug improved static and dynamic lung hyperinflation (evidenced by reduced trapped air volume and increased tidal volume and end-of-exercise inspiratory capacity), and improved exertional dyspnea (during activities of daily living and exertion) and exercise tolerance compared with placebo in randomized, double-blind studies. In patients with stable COPD, improved sleep-related oxygen desaturation that was unaffected by the timing of the daily dose was seen with tiotropium but not with placebo. Clinically significant treatment-related disorders of conduction or rhythm, or changes in heart rate were not observed with tiotropium in this patient group. Mean maximal plasma concentrations (C(max)) were observed within 5 minutes of inhalation of a single dose of tiotropium 18 micrograms in patients with COPD. Plasma drug levels declined to minimum concentrations (C(min)) within 1 hour of treatment in healthy volunteers. Mean steady-state C(max) concentrations (16 ng/L) were achieved after 2-3 weeks of once-daily inhaled tiotropium 18 micrograms in elderly patients with COPD; tiotropium does not appear to accumulate once steady-state has been achieved.The estimated absolute bioavailability of tiotropium at steady state in healthy volunteers was approximately 20-25%, and approximately 72% of the drug is bound to plasma proteins. Excretion of tiotropium is predominantly renal (through active secretion by the kidneys), although in vitro studies suggest that cytochrome P450 (CYP) oxidation (possibly involving CYP2D6 and CYP3A4 enzymes) may have a minor role. In patients with COPD, renal excretion of the unchanged drug at 24 hours (Ae(24)) was approximately 7%. The mean plasma elimination half-life after single or multiple doses in healthy volunteers and elderly patients with COPD was approximately 5-6 days. The renal clearance and urinary excretion of tiotropium decrease with increasing age; however, these changes are not considered to be clinically significant. Because of altered steady-state C(max), C(min), area under the concentration-time curve, and Ae(24) values, caution is required with tiotropium administration in patients with moderate-to-severe renal impairment. The pharmacokinetics of tiotropium in patients with severe renal or hepatic impairment have not been studied. Tiotropium does not interact with drugs such as cimetidine or ranitidine, which are also eliminated by active renal secretion. Orally inhaled tiotropium bromide has been evaluated as a bronchodilator for the management of patients with COPD in randomized, double-blind 6-month and 1-year trials, and in several shorter studies. In clinical trials, COPD was diagnosed according to the American Thoracic Society guidelines. The bronchodilator effect was expressed as the trough FEV(1) response (the mean change in FEV(1) from baseline measured 1 hour prior to and immediately before a scheduled dose), and was the primary endpoint in all but two clinical trials. The bronchodilator effect with tiotropium 18 micrograms once daily was superior to that with placebo in several well designed trials in patients with COPD. Moreover, greater improvements in mean peak and average FEV(1) responses occurred with tiotropium but not with placebo. Mean trough, peak, and average FVC responses, and weekly mean morning and evening PEFR values were also improved to a greater extent with tiotropium than with placebo. Tiotropium demonstrated a greater bronchodilator effect than ipratropium bromide (hereafter referred to as ipratropium when used at approved dosages) 40 micrograms four times daily in two 1-year trials in patients with COPD. Mean peak and average FEV(1), mean trough FVC responses, and weekly mean morning and evening PEFR values were also increased to a greater extent with tiotropium than with ipratropium. In one of the two 6-month trials that compared the efficacy of tiotropium with that of inhaled salmeterol 50 micrograms twice daily, greater improvements from baseline in mean trough, peak, and average FEV(1) and FVC responses were seen with tiotropium than with salmeterol. Increases in weekly mean evening, but not morning, PEFR values were generally greater with tiotropium than salmeterol. In the second trial, improvement in the primary endpoint (mean trough FEV(1) response from baseline) with tiotropium or salmeterol was similar, although peak and average responses were superior with tiotropium. Preliminary results from a 6-week crossover study in patients with COPD suggested that tiotropium alone or in combination with once-daily formoterol improved mean trough and average FEV(1) and trough FVC values from baseline to a greater extent than twice-daily formoterol. More patients achieved a clinically important improvement (increase of &gt;/=1 unit) in the transitional dyspnea index focal score (a measure of dyspnea-related impairment) with tiotropium than with placebo in the 1-year trials. Tiotropium was superior to ipratropium in 1-year trials, and was at least as effective as salmeterol in 6-month trials, in achieving a clinically important improvement in focal scores. Tiotropium recipients experienced fewer COPD exacerbations than placebo or ipratropium recipients and had fewer and shorter COPD-related hospitalizations compared with placebo recipients. Unlike salmeterol, tiotropium lengthened the time to onset of the first exacerbation and decreased the number of exacerbations compared with placebo in two 6-month trials. Similar proportions of tiotropium, salmeterol, and placebo recipients required COPD-related hospitalizations.

Demographics, clinical evaluation, spirometry, peripheral oxygen saturation, body composition, 6-minute walking distance, dyspnea, and quality of life measurements were obtained at baseline. Patients were followed up for 1 year or until death, and information on exacerbation was collected. The median annual exacerbation rate was 0.8. Logistic regression showed that the relationship between the risk for moderate/severe exacerbations during a 1-year follow-up for the GOLD stage was odds ratio: 2.01; 95% confidence interval: 1.39-2.98 and for the BODE index was odds ratio: 2.08; 95% confidence interval: 1.27-3.61.

Several risk factors have been identified, with cigarette smoking being the most important. Diagnostic assessment is based on symptoms, risk of exacerbations and results of lung function testing. A fixed post-bronchodilator ratio for forced expiratory volume in one second to forced expiratory volume (FEV1/FVC) of &lt;0.7 is required to make the diagnosis, and the severity of airflow obstruction defines the grade according to GOLD (Global Strategy for the Diagnosis, Management, and Prevention of COPD). The GOLD strategy makes therapeutic recommendations taking into account the grade, symptomatic assessment and future risk of exacerbations. This review focuses on the therapeutic options for COPD, in accordance with the GOLD strategy. Smoking cessation is the most effective treatment option in all COPD stages. Bronchodilators, namely long-acting antimuscarinic drugs and long-acting beta-agonists, form the mainstay of treatment in COPD. Patients with frequent exacerbations also benefited from the addition of inhaled corticosteroids. Roflumilast is an add-on option for patients with severe COPD. Several controversies are the subject of discussion: (1.) whether pharmacotherapy can modify the natural history of COPD; (2.) whether pharmacotherapy should be started in the early stages of COPD; (3.) the impact of therapy on comorbidities; (4.) whether patients benefit from a combination therapy with a long-acting beta-agonist, a long-acting antimuscarinic drug and an inhaled corticosteroid; (5.) step-down therapy. This overview also reviews the evidence for recommended vaccines in COPD, as well as nonpharmacological therapies. Rehabilitation is an essential part of COPD treatment. Oxygen therapy, noninvasive nocturnal ventilation and surgical treatment options only apply to a highly selected group of patients. Disease management programmes and guideline adherence are briefly discussed. In conclusion, although there is debate as to the extent with which pharmacological therapies influence mortality, adherence to the GOLD strategy is recommended." }, { "id": "pubmed23n0347_9924", "title": "Oral corticosteroids in patients admitted to hospital with exacerbations of chronic obstructive pulmonary disease: a prospective randomised controlled trial.", "score": 0.00909090909090909, "content": "The role of oral corticosteroids in treating patients with exacerbations of chronic obstructive pulmonary disease (COPD) remains contentious. We assessed in a prospective, randomised, double-blind, placebo-controlled trial the effects of oral corticosteroid therapy in patients with exacerbations of COPD requiring hospital admission. We recruited patients with non-acidotic exacerbations of COPD who were randomly assigned oral prednisolone 30 mg once daily (n=29) or identical placebo (n=27) for 14 days, in addition to standard treatment with nebulised bronchodilators, antibiotics, and oxygen. We did spirometry and recorded symptom scores daily in inpatients. Time to discharge and withdrawals were noted in each group. We recalled patients at 6 weeks to repeat spirometry and collect data on subsequent exacerbations and treatment. Hospital stay was analysed by intention to treat and forced expiratory volume in 1 s (FEV1) according to protocol. FEV1 after bronchodilation increased more rapidly and to a greater extent in the corticosteroid-treated group: percentage predicted FEV1 after bronchodilation rose from 25.7% (95% CI 21.0-30.4) to 32.2% (27.3-27.1) in the placebo group (p&lt;0.0001) compared with 28.2% (23.5-32.9) to 41.5% (35.8-47.2) in the corticosteroid-treated group (p&lt;0.0001).

Antibiotics are indicated when a patient notes increased sputum production, purulent sputum, increased dyspnea, has an elevated white count, or is febrile. Examples of first-line antibiotics are amoxicillin, doxycycline, and co-trimoxazole. Mechanical ventilation Severe exacerbations can require hospital care where treatments such as oxygen and mechanical ventilation may be required.

Pulmonary blood flow was twice the systemic blood flow (P less than 0.005). Coronary angiograms performed in 6 patients showed three vessel disease in 5 cases. Five patients underwent surgery. Three of them survived. All of the 17 patients who had medical treatment died. Ten within the first week after AMI, 5 within the first month and 2 late deaths. Autopsy was performed in 15 cases. Eighty percent had coronary narrowing in several vessels. SR measured between 5 and 20 millimeters in 78% and was found in the anterior septum in 61%. In the cases who were in shock, the ventricular myocardium was extensively damaged. We conclude that once the diagnosis of SR is established, the patient should undergo surgical closure of the SR and coronary revascularization if necessary. Early surgical indication is particularly important in patients at risk of developing shock." }, { "id": "pubmed23n0882_21093", "title": "A case of recent myocardial infarction with cardiac failure.", "score": 0.013105205678922462, "content": "A 50-year-old hypertensive smoker presented with a typical angina of 2 days duration.

The electrocardiogram demonstrated dynamic changes following admission, and the myocardial markers returned to normal, but the echocardiography revealed a ventricular septal defect. The initial diagnosis was ventricular septal perforation because of myocardial infarction with acute anterior ST-segment elevation. Coronary angiography revealed no abnormalities, but left ventricular angiography revealed an enlarged apex and VSD, with a right ventricular shunt bundle. Later, cardiac MRI revealed an apical ventricular septal defect. Further inquiry of the patient's medical history revealed that her husband died unexpectedly three months ago, and her daughter was seriously injured in a car accident, causing the patient severe emotional distress. Takotsubo syndrome was then determined in conjunction with the patient's medical history, symptoms, signs, and pertinent examinations. Without using a catheter or a surgical procedure, we managed the patient's medical condition. Two weeks later, the patient was discharged with symptoms improved. Takotsubo syndrome is comparable to an acute myocardial infarction on clinical and electrocardiographic examination in the absence of significant coronary disease.

Neuropathic pain often includes symptoms such as burning or shooting sensations, abnormal sensitivity to normally painless stimuli, or an increased sensitivity to normally painful stimuli. Neuropathic pain is a common symptom in many diseases of the nervous system. Opioid drugs, including morphine, are commonly used to treat neuropathic pain. Most reviews have examined all opioids together. This review sought evidence specifically for morphine; other opioids are considered in separate reviews. To assess the analgesic efficacy and adverse events of morphine for chronic neuropathic pain in adults. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase for randomised controlled trials from inception to February 2017. We also searched the reference lists of retrieved studies and reviews, and online clinical trial registries. We included randomised, double-blind trials of two weeks' duration or longer, comparing morphine (any route of administration) with placebo or another active treatment for neuropathic pain, with participant-reported pain assessment. Two review authors independently extracted data and assessed trial quality and potential bias. Primary outcomes were participants with substantial pain relief (at least 50% pain relief over baseline or very much improved on Patient Global Impression of Change scale (PGIC)), or moderate pain relief (at least 30% pain relief over baseline or much or very much improved on PGIC). Where pooled analysis was possible, we used dichotomous data to calculate risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) or harmful outcome (NNH). We assessed the quality of the evidence using GRADE and created 'Summary of findings' tables. We identified five randomised, double-blind, cross-over studies with treatment periods of four to seven weeks, involving 236 participants in suitably characterised neuropathic pain; 152 (64%) participants completed all treatment periods. Oral morphine was titrated to maximum daily doses of 90 mg to 180 mg or the maximum tolerated dose, and then maintained for the remainder of the study. Participants had experienced moderate or severe neuropathic pain for at least three months. Included studies involved people with painful diabetic neuropathy, chemotherapy-induced peripheral neuropathy, postherpetic neuralgia criteria, phantom limb or postamputation pain, and lumbar radiculopathy. Exclusions were typically people with other significant comorbidity or pain from other causes.Overall, we judged the studies to be at low risk of bias, but there were concerns over small study size and the imputation method used for participants who withdrew from the studies, both of which could lead to overestimation of treatment benefits and underestimation of harm.There was insufficient or no evidence for the primary outcomes of interest for efficacy or harm. Four studies reported an approximation of moderate pain improvement (any pain-related outcome indicating some improvement) comparing morphine with placebo in different types of neuropathic pain. We pooled these data in an exploratory analysis. Moderate improvement was experienced by 63% (87/138) of participants with morphine and 36% (45/125) with placebo; the risk difference (RD) was 0.27 (95% confidence interval (CI) 0.16 to 0.38, fixed-effects analysis) and the NNT 3.7 (2.6 to 6.5). We assessed the quality of the evidence as very low because of the small number of events; available information did not provide a reliable indication of the likely effect, and the likelihood that the effect will be substantially different was very high. A similar exploratory analysis for substantial pain relief on three studies (177 participants) showed no difference between morphine and placebo.All-cause withdrawals in four studies occurred in 16% (24/152) of participants with morphine and 12% (16/137) with placebo. The RD was 0.04 (-0.04 to 0.12, random-effects analysis). Adverse events were inconsistently reported, more common with morphine than with placebo, and typical of opioids. There were two serious adverse events, one with morphine, and one with a combination of morphine and nortriptyline. No deaths were reported. These outcomes were assessed as very low quality because of the limited number of participants and events.

This retrospective analysis involved 106 consecutive in-patients who received either conservative treatment (Group I) or an additional EI on the first day of their treatment (Group II). Both groups were divided according to the duration of symptoms at the time of admission (less than three months, or more than six months). Propensity score matching was performed for the whole collective and the resulting subgroups. This incorporated gender, age and pain intensity at the time of admission. The target parameter were changes on a visual analogue scale (VAS) of pain intensity on days D1, D3, and D10 depending on the respective treatment. A routine evaluation of the mental variables anxiety, depression and somatisation was performed as part of the examination upon admission and their relationship to the success of treatment was later assessed. The mean age of the patients was 61.7 (± 11.6) in Group I and 63.6 (± 13.6) in Group II. 59 % of the patients were female (n = 63). The Lasègue sign was prevalent in 45 % of Group I and 51 % of Group II. The intensity of pain on the day of admission was similar in both groups (7.0 ± 1.0 for Group I, 6.7 ± 1.8 for Group II). The length of stay on the ward was also similar in both groups (10.2 ± 3.9 and 9.4 ± 3.7 d, respectively). It was found that, independent of the duration of symptoms, injection treatment was significantly more effective than conservative treatment only in the early stages (D1 and D3, p &lt; 0.001). No differences could be found in the expression of these mental variables between treatment groups, as these factors showed no influence on the results of therapy. In the context of acute treatment a once only lumbar caudal epidural injection represents at most a short-term effectiveness for the therapy of sciatica.

In vivo electrophysiologic techniques were subsequently used to record evoked dorsal horn neuronal responses in which the effects of systemic morphine and gabapentin were investigated, both individually and in combination. Morphine (1 and 4 mg/kg) inhibited neuronal responses of control rats but not after neuropathy. Gabapentin (10 and 20 mg/kg) inhibited neuronal responses in nerve injured rats and to a lesser extent in sham rats but not in naive rats.

After neuropathy, inhibitions mediated by morphine were significantly increased in the presence of gabapentin compared with morphine alone. After spinal nerve ligation, the inhibitory effects of systemic morphine on evoked dorsal horn neuronal responses are reduced compared with control, whereas the effectiveness of systemic gabapentin is enhanced.

Normally, cytokine production in and around the wounded area increases in order to fight infection and control healing (and, possibly, to control pain), but pre-incisional morphine administration (0.1 mg/kg to 10.0 mg/kg) reduced the number of cytokines found around the wound in a dose-dependent manner. The authors suggest that morphine administration in the acute post-injury period" }, { "id": "pubmed23n1006_216", "title": "Microsurgery versus Medical Treatment for Neuropathic Pain Caused by Foraminal Extraforaminal Lumbar Disc Herniation: An Observational Study.", "score": 0.009009009009009009, "content": "To investigate the incidence of neuropathic pain (NP) in patients with foraminal/extraforaminal lumbar disc herniation (FEFLDH), the prognosis of NP and the effect of microsurgery on patients treatment.

Three months later, he developed constant and burning pain within the entire right side of his body. He was diagnosed with central pain syndrome and treated with antiepileptics and tricyclic antidepressants. Minimal analgesia was achieved, which was limited by intractable sedation and drowsiness. Patient was then treated with oral opioids (morphine and hydrocodone with acetaminophen) in escalating doses that produced cognitive impairment. After an opioid rotation was attempted, by switching morphine to transdermal fentanyl, there was no pain reduction or improved quality of life. A trial of buprenorphine was initiated, by administering transdermal patches in escalating doses in weekly intervals. Patient's pain was eventually successfully controlled with buprenorphine patch 60 μg/h every 7 days. His self-reported Visual Analogue Scale pain scores decreased from an average of 8/10 to 2/10 or less. Patient's overall function and participation in home activities increased. Buprenorphine is a partial μ-receptor and a κ-δ receptor antagonist known to block NMDA receptors and reduce hyperalgesia secondary to central sensitization.(1) Buprenorphine is also a partial agonist at the opioid receptor-like (ORL-1) receptor, which is found to be analgesic and antinociceptive at the level of the spinal cord.(1,2) The difference in analgesic responses between buprenorphine and other opioids may be due to different receptor G protein interactions and/or selective activation of neuronal K(ATP) channels by buprenorphine.(3) Deficient opening of K(ATP) channels has been shown to mediate neuropathic pain(4); therefore, activation of these channels by buprenorphine may contribute to its analgesic effect in neuropathic pain states wherein other opioids fail. More recently, there have been two case reports in which patients with neuropathic pain of different central etiology were successfully treated with buprenorphine.(5) Despite advances in understanding the pathology related to central pain, effective treatment options are limited.

Their use, however, is limited by decreased effects in neuropathic and chronic pain as a result of increased pain and development of tolerance. Gabapentin (GBP) is effective in both experimental models of chronic pain and clinical studies of neuropathic pain. Therefore, we investigated, in a randomized, placebo-controlled, double-blinded study, the pharmacodynamic and pharmacokinetic interaction of GBP and morphine in 12 healthy male volunteers. Morphine (60 mg, controlled release) or placebo was administered at 8:00 AM, and GBP (600 mg) or placebo was administered at 10:00 AM, thus comparing the analgesic effect of placebo + GBP (600 mg) with placebo + placebo and morphine (60 mg) + GBP in comparison to morphine plus placebo by using the cold pressor test. The duration and intensity of the side effects were assessed by using visual analog scales. The analgesic effect was evaluated by the change in the area under the curve (h x %; 0% baseline before Medication 1) of pain tolerance. Placebo + GBP (18.9% x h, 95% confidence interval [CI]: -2.5 to 40.3) did not present any significant analgesic effect compared with placebo + placebo (4.7% x h, 95% CI: -16.7 to 26.1). A significant increase in pain tolerance was observed comparing the combination of morphine and GBP (75.5% x h, 95% CI: 54.0-96.9) with morphine + placebo (40.6% x h, 95% CI: 19. 2-62.0). The observed adverse events after placebo + GBP were not significantly different compared with placebo + placebo. Morphine + placebo led to the expected opioid-mediated side effects. They were significantly more pronounced compared with placebo + placebo but did not differ significantly compared with the combination of morphine + GBP. Concerning the pharmacokinetic variables of morphine and its glucuronides, no significant difference between morphine + placebo and morphine + GBP was observed, whereas the area under the curve of GBP (43.9 +/- 5.3 vs 63.4 +/- 16.2 microg. h(-1). mL(-1), P &lt; 0.05) significantly increased, and apparent oral clearance (230.8 +/- 29.4 mL/min vs 178 +/- 97.9 mL/min, P = 0.06) and apparent renal clearance (86.9 +/- 20.6 vs 73.0 +/- 24.2 mL/min, P = 0.067) of GBP decreased when morphine was administered concomitantly. These results suggest two different sites for the pharmacokinetic interaction-one at the level of absorption and the other at the level of elimination. Our study reveals both a pharmacodynamic and pharmacokinetic interaction between morphine and GBP, leading to an increased analgesic effect of morphine + GBP. These results and the good tolerability of GBP should favor clinical trials investigating the clinical relevance of the combination of morphine and GBP for treating severe pain. In a randomized, placebo-controlled, double-blinded trial with 12 healthy volunteers, we studied the interaction of morphine and gabapentin using the cold pressor test. The anticonvulsant gabapentin enhanced the acute analgesic effect of morphine. Furthermore, the plasma concentration of gabapentin was increased when morphine was administered concomitantly. Therefore, the well tolerated combination of gabapentin and morphine may improve pain therapy, especially in pain states, like chronic and neuropathic pain, which respond poorly to opioids." } ] } } }

He notes that his left eyelid is more droopy and that the pupil of this eye is smaller. John reports that the medial side of his left hand is numb and with less strength. His physician checks for palpebral ptosis and left miosis; he checks that he can close both eyelids symmetrically and that both pupils respond correctly to light. In addition, he checks that there is no sweating from the left hemiface, that he feels less prickling on the inner surface of the left hand and that he has less strength in the grip of the left hand.

Photoreceptor cells in the outer layers of the retina, which are called rods and cones, convert light stimuli into neuronal impulses. These signals are then relayed to the bipolar cells, which interact with ganglion cells, which in turn coalesce to form the optic disc and optic nerve (CN II). The optic nerve sends impulses to the brain for further processing and image recognition. [1] These are the first steps of the pupillary light reflex afferent pathway. The optic nerve then forms the optic chiasm, which diverges into a left and right optic tract. At the optic chiasm, nasal retinal fibers will cross to the contralateral side of the optic tract, and the temporal retinal fibers continue on the ipsilateral side. Thus, the right optic tract will contain temporal retinal fibers from the right eye, as well as nasal retinal fibers from the left eye. The optic tracts join the brachium of the superior colliculus, and then signals travel to the pretectal area of the midbrain. Each pretectal area sends bilateral signals to the preganglionic parasympathetic nuclei in the midbrain called Edinger-Westphal nuclei. [2] [3] There are a minority of axons that go to the hypothalamus and the olivary pretectal nucleus (OPN). [4] Efferent parasympathetic preganglionic fibers travel on the oculomotor nerve and synapse with the ciliary ganglion, which sends postganglionic axons to directly innervate the iris sphincter muscles. The contraction of the iris sphincter muscles leads to pupillary constriction (miosis). [3] This extensive pathway is being tested when a light is shined in the eyes. And, because of the crossing fibers, there is not only a direct pupillary reflex but also a consensual pupillary light reflex.

Hasegawa dementia scale was 28.5/32.5. Upward gaze was slightly restricted (3/5). Cranial nerve examination revealed oculogyric crisis, apraxia of eyelid opening, masked face, and small voice. He was able to stand with support; his posture showed left-ward leaning. He had right hemiparesis with moderate weakness. He showed marked bradykinesia and moderate rigidity in his left upper extremity. Fine postural tremor was noted in the left hand. Deep tendon reflexes were diminished in the upper extremities. No Babinski sign was noted. Pain sensation was somewhat diminished on the right side. Results of routine laboratory examination were unremarkable. Cranial CT scan revealed atrophy in the frontal lobe, particularly in the prefrontal area. In addition, MRI revealed T1-and-T2-low signal intensity lesions in the right ventral pallidal region and in the left ventrolateral thalamic-hypothalamic areas. He was treated with 600 mg of levodopa with benserazide and 22.5 mg of bromocriptine with mild to moderate improvement in his bradykinesia and rigidity. He was discharged in January 1991.

In the substantia nigra, neuronal loss was particularly severe in the ventrolateral area. No Lewy bodies were seen. The dorsal motor nucleus of the vagal nerve was well preserved. Stereotaxic lesions involved bilateral thalamic areas. This patient appears to represent a case of autosomal recessive juvenile parkinsonism (AR-JP). Early onset, superb response to levodopa, sleep effect, and easy development of dyskinesias and motor fluctuations characterize AR-JP.

A 29-year-old woman presented at 19 weeks' gestation with severe preeclampsia and vaginal bleeding. Pelvic ultrasonography demonstrated a molar pregnancy.

WHO modified its risk factor scoring system. This change was proposed to combine both the basic FIGO anatomic staging with the modified WHO risk factor scoring system. Patients who score as low-risk are treated with single agent chemotherapy, such as methotrexate (MTX), and patients refractory to MTX are treated with a combination chemotherapy, EMA/CO. Patients who score as high-risk are treated with EMA/CO, and patients refractory to the first line chemotherapy may be successfully treated with EP/EMA. Recent epidemiological data showed that women with complete hydatidiform moles could anticipate normal reproduction in the future. Studies found that pregnancies after treatment of molar pregnancy resulted in 69% full-term, live births; 8% premature deliveries; 1% ectopic pregnancies, and 0.5% stillbirths. First-trimester spontaneous abortions occurred in 17% of pregnancies, and major and minor malformations were detected in 0.4% of infants. Patients with hydatidiform mole were at increased risk of developing molar pregnancy in subsequent conceptions. After having one molar pregnancy, the risk of having molar disease in a future gestation was about 1%. The risk of persistent gestational trophoblastic tumors was increased by long-term oral contraceptive use before conception. In a large, multicenter, case-control study, the risk was shown to be increased in women who had ever used oral contraceptives, but was highest for women taking oral contraceptives during the cycle in which they became pregnant.

Serum hCG is measured on suspicion of hydatidiform mole. At the time of the uterine evacuation, the initial hCG is measured (A). After a hydatidiform mole that is both triploid and partial, serum hCG is measured weekly until there are two consecutive undetectable values (&lt; 1 or &lt; 2), after which the patient can be discharged from follow-up (C). After a diploid hydatidiform mole, a complete mole, or a hydatidiform mole without valid ploidy determination, serum hCG is measured weekly until the value is undetectable (&lt; 1 or &lt; 2). If serum hCG is undetectable within 56 days after evacuation, the patient can be discharged from follow-up after an additional four monthly measurements.

The 32 molar pregnancies progressed to 24 cases of spontaneous remission and eight cases of persistent trophoblastic disease. Among patients with spontaneous remission, the time at which serum hCG levels became undetectable and the onset of first postabortion menstruation were similar to those in patients who had nonmolar abortions. In all patients who experienced regression, serum hCG was undetectable after the third postabortion menstruation. In all patients with persistent trophoblastic disease, serum hCG levels exceeded 25 milli-international units/mL 4 weeks after evacuation.

The correct answer is 4. What is not very clear to me is "routine urinalysis" because it is not usually done in an asymptomatic healthy child. Microhematuria without associated symptoms may be a finding without pathologic significance and must be confirmed in a subsequent new sediment (although I do not know if at 15 days or later).

Patients usually present non-specific symptoms and signs so that the diagnosis of ATIN is often delayed. The disease may be infection- or drug-induced or it may occur without a known cause. Early recognition and appropriated therapy usually lead to an excellent prognosis. The aim of the study was to describe clinical and laboratory findings and the course of ATIN in 21 patients, that are typical enough to enable early recognition of the disease as it is potentially reversible. Between 1986 and 1997 we observed 21 patients, aged 7-16 years (mean, 12.8), with acute tubulointerstitial nephritis, including eight with tubulointerstitial nephritis and uveitis (TINU syndrome). Laboratory studies included urinalysis, complete blood count, erytrocyte sedimentation rate (ESR), plasma creatinine, glomerular filtration rate (GFR), electrolytes, proteins, IgG, C3, C4 antinuclear-antibodies (ANA), antistreptolysin-O and antibodies to hantaviruses. Renal ultrasound was done in all patients. Renal biopsy was performed in 5 children. All children had previously been healthy. The symptoms of ATIN developed within a few days (Table 1). The most common initial symptoms were fatigue, fever, gastrointestinal disturbances, anorexia and weight loss. Less common complaints included headache, arthralgias and maculopapular rash. On addmition no patient had hypertension, oedema or evidence of acute infection. ESR, plasma urea and creatinine concentrations were increased in all, plasma proteins and IgG levels in the majority of patients. ANA were negative in 15 pts in whom this analysis was performed; C3 and C4 levels were normal. In two children recent strepococcal and in the other 6 hantavirus infection was serologicaly proved. All patients had non-oliguric acute renal failure (ARF): GFR was 21.7 +/- 8 9 in 14 pts and 67 +/- 9.7 in 7 pts. Low urine specific gravity (1003-1014), mild proteinuria (0.3-0.4 g/24 h), leukocyturia and/or haematuria were found in all patients; glycosuria, aminoaciduria and decreased tubular reaposrption of phosphate (TRP) were found in 12/21, 9/21 and 9/14 patients, respectively. Urine cultures were negative in all children. Renal US demonstrated enlarged hyperechoic kidneys in 11 pts, in remaining 10 pts no abnormalities were found. Renal biopsy, performed in 5 children, confirmed the diagnosis of ATIN. Eight patients subsequently developed anterior uveitis as part of TINU syndrome. Treatment included supportive therapy in all and six patients received prednisolone for 4-8 weeks (40-60 mg/m2/24 h for 10-14 days with subsequent reduction of dose over several weeks). Anterior uveitis was successfully treated with topical steroids. Renal function completely recovered in all patients: GFR (109 +/- 22.6 ml/min) within a mean interval of 47 +/- 33 days, concentration ability within 2-12 (mean 4.5) months. Common clinical features of ATIN are non-oliguric acute renal failure of various degrees, signs of tubular dysfunction, proteinuria, haematuria, leukocyturia and absence of hypertension. All our patients had normal blood pressure, non-oliguric renal failure, proteinuria, hypostenuria and abnormal urinary sediment; about half of them had glycosuria and/or other signs of proximal tubular dysfunction. The most important causes of ATIN in children reported in literature are systemic infections and drugs. However, the cause of ATIN in our patients was assessed as being related to infection only in 8 patients and to diclofenac in one. No infection, drug, toxin or other cause could be identified in 4, as well as in 8 pts with TINU syndrome. The prognosis of ATIN in children is considered to be favourable, but some patients may develop chronic renal failure. Renal function completely recovered in all our patients; that is consistent with outcome data from the most reports. Acute tubulointerstitial nephritis is an important cause of ARF in children, its aetiology may be different and it carries an excellent prognosis. ATIN should be suspected in a child who presents typical, although non-specific symptoms and signs, associated with lukocyturia and/or microhaematuria, signs of tubular dysfunction and unexplained renal failure. The diagnosis can be verified at renal biopsy. Early recognition of the disease is important to remove possible aetiologic agents and to treat them before chronic lesions are present to avoid long-term renal damage." }, { "id": "pubmed23n0417_5268", "title": "Cases from the Osler Medical Service at Johns Hopkins University.

Blood routine tests were performed with hemoglobin (HGB) 57 g/L. Urine routine: BLD (3+). 24-hour urinary protein 3.2 g. serum albumin 20.5 g/L, C-reactive protein (CRP) 12.85 mg/L, erythrocyte sedimentation rate (ESR) 140 mm/h. Antinuclear antibody (ANA) (H)1:10 000, anti-dsDNA antibody 1:3 200; anti-Smith antibody, anti-U1-snRNP/Sm antibody were positive, blood complement 3(C3) 0.43 g/L, complement 4(C4) 0.07 g /L. Anticardiolipin antibody (ACL), anti-β2-GP1, lupus anticoagulant (LA) were negative; HRCT suggested bilateral medial pleural cavity product liquid. Admission diagnosis: SLE lupus nephritis, anemia, pleural effusion, and hypoproteinemia. We treated her with methylprednisolone 1 000 mg×3 d, late to 48 mg/d and cyclophosphamide 1.0 g, HCQ 0.2 g bid, gamma globulin 10 g×5 d. Day 2 of treatment, this patient developed acute right upper quadrant pain, not accompanied by nausea, vomiting, blood stool and diarrhea. Antipyretic antispasmodic treatment was invalid, after the morning to ease their own abdominal pain. Day 4 of treatment, daytime blood HGB 77 g/L. Bilateral renal vascular ultrasound: bilateral renal artery blood flow velocity was reduced. The abdominal pain of the above symptoms recurred at night, BP was 120/80 mmHg, and no positive signs were found on abdominal examination. No abnormality was found in the vertical abdominal plain film. Blood routine examination: HGB 53 g/L, Plasma D dimer 2 515 μg/L, amylase in hematuria was normal, the stool occult blood was negative. Abdominal computed tomography (CT): normal structure of right adrenal gland disappeared, irregular mass shadow could be seen in adrenal region, CT value was about 50 HU. Morphological density of left adrenal gland was not abnormal. The retroperitoneum descended along the inferior vena cava to the right iliac blood vessel and showed a bolus shadow. The density of some segments increased. The lesion involved the right renal periphery and reached the left side of abdominal aorta. Most lesions surrounded the inferior vena cava, the right renal vein and part of the small intestine. The boundary between the upper lesion and the vena cava was unclear. Iodinecontaining contrast agent was taken orally. No sign of contrast agent overflowing was found in the abdominal cavity. Hematoma and exudative changes were considered in retroperitoneum. CONCLUSION of contrast-enhanced ultrasound of blood vessels: The retroperitoneal inferior vena cava (volume 3.5 cm×3.5 cm×1.5 cm) was hypoechoic and had no blood flow lesion. The adrenal gland had a high possibility of origin. Left renal vein thrombosis extended to inferior vena cava. According to the above data, it was analyzed that the cause of retroperitoneal hematoma of the patient was left adrenal vein thrombosis caused by hypercoagulable state, which led to vascular rupture and hemorrhage caused by increased vascular pressure in adrenal gland. Therefore, on the basis of continuing to actively treat the primary disease, and on the basis of dynamic observation of no active hemorrhage for 3 days, the anticoagulant therapy was continued with 10 mg/d of apixaban. Clinical symptoms were gradually eased, HGB did not decrease. Two weeks later, the ultrasonic examination showed that the irregular cluster hypoechoic range behind the inferior vena cava was significantly smaller than that before (1.8 cm×1.2 cm×0.7 cm). Abdominal CT examination after 1 month showed that there was no abnormal morphological density of bilateral adrenal glands and basic absorption of retroperitoneal exudation. Adrenal hemorrhage is uncommon. SLE with adrenal hemorrhage is rarer. In SLE patients, especially those complicated with APS, if abdominal pain accompanied by HGB decrease occurs, except after gastrointestinal hemorrhage, the possibility of adrenal hemorrhage should be warned." }, { "id": "pubmed23n0392_8074", "title": "Atherosclerotic Renovascular Disease.", "score": 0.014250493096646943, "content": "The patient, a 78-year-old Asian male, was brought to the hospital because of acute shortness of breath that had progressively worsened over the course of the day. He complained of a nonproductive cough and claudication after walking 1 block. His past medical history was significant for mild renal insufficiency (serum creatinine 1.5--2.0 mg/dl), the etiology of which was never explored. Although there was a recent history of mild to moderate hypertension, at presentation his blood pressure was noted to be 240/118 mm Hg in both arms. His physical exam at the time of admission was remarkable for grade II hypertensive retinopathy, an S4 gallop, periumbilical systolic bruits, audible femoral arterial bruits and absent distal lower extremity pulses. Initial complete blood count, serum electrolytes and cardiac enzymes (including lactate dehydrogenase) were normal. His blood urea nitrogen and serum creatinine concentrations were 51 and 3.6 mg/dl, respectively, and his urinalysis showed 1+ protein (both by dipstick and sulfasalicylic acid) with a \"benign\" sediment (0--1 WBC/HPE, 1--2 RBCs/HPF) with occasional granular casts. His electrocardiogram, apart from demonstrating left ventricular hypertrophy with secondary ST-T wave abnormalities, showed no acute changes; his chest X-ray demonstrated cardiomegaly and pulmonary vascular congestion. He was intubated and subsequently treated with increasing parenteral doses of furosemide (40--240 mg) and a nitroglycerine drip (up to 15 mcg/min). Over the course of the first 48 h, his blood pressure was gradually lowered to 170/100 mm Hg. His urine output increased from 20 ml/h to 125/ml/h, and his respiratory status improved, allowing him to be extubated. In spite of adequate control of his blood pressure in the ensuing days (150--170/80--90 mm Hg), his renal function continued to deteriorate. Renal sonography (without Doppler) demonstrated a right kidney of 9.6 cm and a left kidney of 9.3 cm in length without evidence of hydronephrosis. Both kidneys were noted to be echogenic. Assays for antinuclear antibodies and antineutrophilic cytoplasmic antibodies were negative, and the patient's serum complement levels were normal. For several days after his admission, his serum creatinine gradually rose to 10.7 mg/dl, and hemodialysis was initiated for uremic encephalopathy. Because of the high index of suspicion for renal artery stenosis as the case of both his hypertension and renal failure, a renal angiogram was performed. It revealed a 90% occlusion of the right renal artery with ostial involvement and a 70% occlusion of the left renal artery; both kidneys had poor distal renal vasculature and there was marked atherosclerotic disease of the aorta. After being hemodialyzed for 3 treatments, his renal function began to improve spontaneously. His serum creatinine returned to 3.4 mg/dl, and a subsequent 24-hour urine demonstrated a creatinine clearance of 20 ml/min and an excretion of 1.2 g of protein. Following his discharge from the hospital, his renal function remained unchanged for 3 years, and his blood pressure was easily controlled on monotherapy with a long-acting calcium channel blocker.

We included the assay of uristatin as part of a screening program carried out by pediatricians on 4207 Japanese schoolchildren to judge the ability of uristatin to identify those with an infection and (or) inflammation of any cause. We used urine dipsticks for the assay of uristatin, creatinine, albumin, blood, leukocyte esterase, and protein. We also performed quantitative assays for uristatin and creatinine. Another aim was to estimate the reference range for uristatin in schoolchildren, ages 5 to 14 yr. We prepared dipstick pads that were impregnated with a chromogenic substrate for trypsin and measured the uristatin-caused inhibition of trypsin in urine. We measured creatinine so that the ratio of uristatin to creatinine could be calculated to correct for urine concentration. We obtained quantitative uristatin and creatinine results for 4207 children. Of these, 177 had an abnormal urine dipstick for albumin or blood or protein or leukocyte esterase or a combination of these. We used data from 3622 children to establish the reference range for the uristatin dipsticks.

We investigated the utility of forwarding clinical and laboratory correspondence to outpatients with extreme value of C-reactive protein (CRP). Sixty-eight outpatients with CRP levels more than 20 mg/dl detected during 1986 were studied. CRP was measured by turbidometric method, and a sample with CRP level more than 15 mg/dl was diluted with CRP negative serum (CRP level less than 0.2 mg/dl) and was reanalyzed. Fifty-two of 68 patients (76%) had infectious diseases as the causal disease of high CRP, and eight (12%) had other diseases. In the remaining (12%) the causes were unknown. In most patients the causal diseases were diagnosed within one or two days, but diagnosis required more than 4 days in those with acute pyelonephritis, meningitis, liver abscess or renal abscess, as these diseases were diagnosed after the examination of urine or cerebrospinal fluid, or after ultrasonography. Thirty-seven of 58 patients (64%) who had appointments with their physician on the day of the laboratory examination were admitted the same day, and two of 10 patients (20%) who had appointments on the following day were admitted on that day. Seventeen of 25 patients (68%) with urea-N levels more than 30 mg/dl, cholinesterase levels less than 0.7 delta pH and albumin levels less than 3.5 g/dl required more than 15 days to recover, while 29 of 32 patients (91%) with only 2 or fewer of these laboratory values required less than 14 days. The prompt notification of extreme CRP value is an important aspect of medical care. The examination of urine and cerebrospinal fluid and ultrasonography are necessary screening techniques accompanying examination of blood and plain chest X-ray.

The natural history of idiopathic scoliosis is a crucial issue in the planning and assessment of different treatment methods. This article presents the evaluation of scoliotic deformity in immature patients who have been in observation without any treatment. Material and methods. 159 patients (128 girls, 31 boys) were examined between 1971 and 2002. Skoliosis was diagnosed at a mean age of 6 years 4 months (range 2.1-8.10), and observation was concluded at a mean age of 16 years 11 months (range 14.6-20.3). The mean follow-up was 10 years 5 months. The prognostic factors analyzed were: age, sex, Cobb angle, Mehta angle, apical vertebral rotation, specific rotation, Risser test. The progression and regression of curvature was analyzed in different biological age periods, and was measured by calculating the difference in the Cobb angle on successive x-rays divided by the interval between x-rays. Results. The mean progression of curvature before age 5 was 5.7 degrees per year; in the 6-10 age bracket, 2.3 degrees per year; in the 11-15 age bracket, 7.4 degrees per year; in the &gt;15 age bracket, 0.3 degrees per year. The mean progression for patients with Risser 1 was 8.8 degrees per year; Risser 2, 7.3 degrees per year; Risser 3, 5.1 per year; Risser 4, 2.1 degrees per year; Risser 5, 0.3 degrees per year. Conclusions. The progression of curvature in idiopathic scoliosis is variable, and is influenced by age. Knowledge of the natural history of idiopathic scoliosis is a crucial tool in predicting the development of spinal curvature. The Risser test and biological age are the only effective predictors of progression." }, { "id": "pubmed23n0825_810", "title": "Effectiveness of brace treatment for adolescent idiopathic scoliosis.", "score": 0.01899189918991899, "content": "Effectiveness of brace treatment for adolescent idiopathic scoliosis (AIS) was demonstrated by the BrAIST study in 2013.

A total of 95 patients (87 girls, 8 boys) were included. At skeletal maturity, 80 patients (84.2%) had 5 degrees or less curve progression and 15 (15.8%) had 6 degrees or more progression. Seven patients (7.8%) were recommended to undergo or underwent surgery before skeletal maturity. Eleven patients (12.6%) progressed beyond 45 degrees.

Physiotherapy in the treatment of scoliosis patients is still regarded as ineffective since the study by the American Orthopedic Association in 1941, which showed that general exercises could not influence the natural history of scoliosis. However, specific exercise programmes were not known in the USA at that time. This preliminary study started in 1989 with the following inclusion criteria: (1) diagnosis of idiopathic scoliosis; (2) risser sign &lt; 4; (3) no treatment other than physiotherapy; (4) first control after 1-3 years during repeated in patient treatment; (5) standing AP radiograph taken not more than 6 months before the first in patient treatment. A total of 181 scoliosis patients, with an average age of 12.7 years and an average angle of curvature of 27% according to Cobb, were included in this study. The average risser sign was 1.4, the average follow-up 33 months. The Cobb angle of the major curve was measured in a standardized way. The results of our preliminary study were compared to natural history as known from literature. For the worst-case analysis additionally a questionnaire was sent to the non-repeaters treated at our centre at the same time (1989 and 1990) as the patient sample described above, taking into account the same inclusion criteria for this patient sample except point 4. Results showed that progression as usually defined (increase in curvature of 5 degrees or more per year) has not been found in the preliminary study. The patient sample of this study was divided into different age groups and different groups of curve magnitude, for comparison with other studies. Additional to the patient sample of the preliminary study, 116 of the patients from the years 1989 and 1990 fulfilled the inclusion criteria of the preliminary study with the exception of point 4. These patients formed the questionnaire sample for the worst-case analysis showing that the progression rate of the 181 patients from the preliminary study and the 116 patients of the questionnaire sample together was still better than natural history even if all drop-outs were considered to be failures. The fact that there was no relative progression in our patients sample treated solely by physiotherapy (preliminary study), seems to show the effectiveness of the inpatient rehabilitation programme even in cases with a bad prognosis, severe angles of curvature and unfavourable curvature patterns. A worst-case analysis does not prevent this conclusion, even if all dropouts from the non-repeaters group were considered as failures." }, { "id": "pubmed23n0830_21807", "title": "Mild angle early onset idiopathic scoliosis children avoid progression under FITS method (Functional Individual Therapy of Scoliosis).", "score": 0.015423410743607788, "content": "Physiotherapy for stabilization of idiopathic scoliosis angle in growing children remains controversial.

We examined a total of 52 patients with an idiopathic scoliosis treated in a thermoplast brace. The group consisted of 38 female and 14 male patients (average age 11.6 years). The angulation was measured with the help of the Cobb-angle and the rotation with the method described by Nash and Moe. The skeletal age was classified according to Risser's-sign. The angle determinations were carried out at three separate points in time--at first presentation, prior to bracing and four to six weeks following bracing. The patients presented with an average angulation of 31 degrees. The average correction achieved in the Wilmington-brace was 41%. This corresponds to a correction of 13 degrees. The best primary correction (45%) was obtained in the thoracolumbar spine. Those patients with the smallest deformity at the onset of treatment showed the best results. The scoliosis with a large primary deformity and a marked rotation of the vertebral bodies responded poorly to correction. Advanced age or skeletal maturity were also limiting factors. Physical therapy had a positive influence on the amount of primary correction obtained. The Wilmington-brace (thermoplast) allows for a good primary correction of idiopathic scoliosis.

All patients included in these groups conformed with the Scoliosis Research Society (SRS) standardized criteria for AIS bracing: (1) Risser &lt; or =2, (2) curve magnitude 25 to 40 degrees, (3) age &gt; or =10 years. Outcomes were SRS standardized with failure being defined as curve progression &gt; or =6 degrees, or ever exceeding 45 degrees, or having surgery recommended before skeletal maturity. All patients were followed through the completion of brace treatment or attainment of other treatment end points. The Yates corrected chi test and unpaired t test were used for data analysis. The 35 patients (32 girls, 3 boys) in the TLSO group had an average age of 13 years (range: 11.1-16.8) and an average primary curve magnitude of 33 degrees (range: 25-40 degrees). Follow-up averaged 2 years (range: 8-61 m) from the beginning of brace treatment. The 32 patients (28 girls, 4 boys) in the SpineCor group had an average age of 13 years (range: 11-15.2) and an average primary curve magnitude of 31 degrees (range: 25-40 degrees). Follow-up for this group averaged 2 years and 6 months (range: 13-73 mo) from the beginning of brace treatment. No significant difference (P=0.75) was found using the more strict outcome measure (&lt; or =5-degree curve progression) as the success rates were 60% (21/35) for TLSO and 53% (17/32) for SpineCor. Similarly, no significant difference (P=0.62) was found using the more liberal outcome measure (never reached 45 degrees) as the success rates were 80% (28/35) for TLSO and 72% (23/32) for SpineCor. We were unable to identify any significant differences in brace treatment outcomes when comparing TLSO and SpineCor treated patients." }, { "id": "wiki20220301en506_25267", "title": "Management of scoliosis", "score": 0.013235294117647059, "content": "Surgery is indicated by the Society on Scoliosis Orthopaedic and Rehabilitation Treatment (SOSORT) at 45 degrees to 50 degrees and by the Scoliosis Research Society (SRS) at a Cobb angle of 45 degrees.

Patient demographics, age at detection, family history, clinical and radiological charts of consecutive patients referred for scoliosis evaluation during the period 2003-2011, were prospectively registered. Patients were recruited from a catchment area of about 500000 teenagers. Maturity was estimated according to Risser sign and menarcheal status. Severity of pain was recorded by a verbal 5-point scale from no pain to pain at all times. Physical and neurological examinations were conducted.

A Case Control Study with Bracing.", "score": 0.010638598873892992, "content": "<bBackground</b: The most common conservative treatment for Adolescent Idiopathic Scoliosis (AIS) is bracing. However, several papers questioned the effectiveness of bracing for curves between 40° and 50° Cobb: the effectiveness in preventing curve progression could be as low as 35%. Seriate casting is considered a standard approach in early onset scoliosis; however, in the setting of AIS, cast treatment is seldom utilized, with only few studies reporting on its effectiveness. <bAim of the study:</b The main aim of the study is to determine whether a seriate casting with Risser casts associated with bracing is more effective in preventing curve progression than bracing alone in curves larger than 40°. Furthermore, the secondary endpoints were: (1) is there a difference in effectiveness of casting between Thoracic (T) and Thoracolumbar/Lumbar (TL/L) curves? (2) Does the 'in cast' correction predicts the treatment outcome? (3) What is the effect on thoracic kyphosis of casting? <bMethods</b: This is a retrospective monocentric case-control study; through an Institutional Database search we identified all the patients treated at our institution between 1 January 2017 and 31 December 2020, with a diagnosis of AIS, Risser grade between 0 and 4 at the beginning of the treatment, at least one curve above 40° Cobb and treatment with either seriate Risser casting and bracing (Study Group, SG) or bracing alone (Control Group, CG). Standing full spine X-rays in AP and LL are obtained before and after the cast treatment; only AP standing full spine X-rays 'in-cast' are obtained for each cast made. Patients were stratified according to the curve behavior at the end of treatment (Risser 5): progression was defined as ≥6° increase in the curve magnitude or fusion needed; stabilization is defined as a change in curve by ±5°; and improvement was defined as ≥6° reduction in the curve. <bResults</b: For the final analysis, 55 compliant patients (12 M, 43 F, mean age 13.5 ± 1.6) were included in the SG and 27 (4 M, 23 F, mean age 13.6 ± 1.6) in the CG. Eight (14.5%) patients in the SG failed the conservative treatment while 14 (51.3%) failed in the CG. Consequently, the Relative Risk for progression in the Efficacy Analysis was 1.8 (95% CI 1, 3-2.6, <ip</i = 0.001), and the Number Needed to Treat was 2,4. No significant difference was found between the T and TL/L curves concerning the 'progressive' endpoint (z-score 0.263, <ip</i = 0.79). The mean percentage of 'in cast' curve reduction was 40.1 ± 15.2%; no significant correlation was found between the percentage of correction and the outcome (Spearman Correlation Coefficient 0.18). Finally, no significant differences between baseline and end of FU TK were found (32° ± 16.2 vs. 29.6 ± 15.8, <ip</i = ns). <bDiscussion:</b Seriate Risser casting for AIS with larger curves (&amp;gt;40° Cobb) is effective in reducing curve progression when compared with full time bracing alone in treatment compliant patients. The treatment is equally effective in controlling T and TL/L curves; furthermore, a slight but non-significant decrease in TK was observed in patients treated with casting. This type of treatment should be considered for AIS patients who present with large curves to potentially reduce the percentage of surgical cases. <bShort Abstract</b: The aim of the study is to determine whether seriate Risser casting associated with bracing is more effective in preventing curve progression than bracing alone in curves larger than 40°. This is a retrospective monocentric case-control study; we identified all the patients treated at our institution with a diagnosis of AIS, Risser grade 0-4 at the beginning of the treatment, at least one curve above 40° Cobb (35° if treated with bracing alone) and treatment with either seriate Risser casting and bracing (Study Group, SG) or bracing alone (Control Group, CG). Fifty-five patients (12 M, 43 F, mean age 13.5 ± 1.6) were included in the SG and 30 (5 M, 25 F, mean age 13.9 ± 1.7) in the CG. Eight (14,5%) patients in the SG failed the conservative treatment while fifteen (50%) failed in the CG. Consequently, the Relative Risk for progression in the Efficacy Analysis was 1.8 (95% CI 1.3-2.6, <ip</i = 0.001), and the Number Needed to Treat was 2,4. Seriate Risser casting for AIS with larger curves (&amp;gt;40°) is effective in reducing curve progression when compared with full time bracing alone.

A prospective study was carried out between 1998 and 2010 at two hospital centers on 33 adolescents and young adult with idiopathic lumbar scoliosis involving curves of three kinds, on whom surgical treatment was performed using a single solid rod.

Revision surgery was undertaken in both cases, only the last plate needed to be replaced and the rod could be kept without any other modification of the construct. In both cases, fusion has been achieved without any loss of correction. The mean loss of correction of the main curve was 2.5° for the three series. Anterior instrumentation of lumbar idiopathic scoliosis gives highly satisfactory morphological and functional results, since the lumbar musculature is spared and the instrumentation placed at the apex of the curvature has selective effects. Despite our preference and that of other surgeons throughout the world for anterior instrumentation, we are still a minority in comparison with the users of posterior instrumentation. There are several reasons for this reticence, including surgeons' training and ideas about pedicular screw fixation, but the main reason has been the lack of a sufficiently exact system of classification. Previous comparative studies between the anterior and posterior approaches have been biased by the use of an excessively restrictive mode of classification (lumbar/thoracolumbar) of the curves. Real lumbar scoliosis, unbalanced thoracolumbar scoliosis and thoracic and lumbar double curve (lumbar predominant) scoliosis should be properly defined before being compared." }, { "id": "wiki20220301en506_25265", "title": "Management of scoliosis", "score": 0.009615384615384616, "content": "Indications for Scoliosis Bracing: Scoliosis professionals determine the proper bracing method for a patient after a complete clinical evaluation.

However until recently no prospective controlled end-result study is presented comparing the results obtained with this soft brace to natural history. The objective was to determine whether the results obtained by the use of the SpineCor are better than natural history during pubertal growth spurt. The method employed prospective comparison of the survival rates of SpineCor treatment vs. natural history with respect to curve progression during pubertal growth spurt. 12 Patients with Cobb angles between 16 and 32 degrees (at average 21 degrees) during pubertal growth spurt are presented as a case series treated with the SpineCor. Survival rate of this sample is described and compared to natural history (SRS brace study 1995). All girls treated in both studies were at risk for being progressive with the first clinical signs of maturation (Tanner 2-3). During the pubertal growth spurt most of the patients (11/12) with SpineCor progressed clinically and radiologically as well (at least 5 degrees). Progression could be stopped changing SpineCor to the Chêneau brace in most of the sample described (7/10). The avarage Cobb angle at the start of treatment with the SpineCor was 21.3 degrees, after an average observation time of 21.5 months 31 degrees. At 24 months of treatment time 33% of the patients with the SpineCor where still under treatment with their original bracing concept, at 72 months follow-up time 8 % of the patients with the SpineCor survived with respect to curvature progression. Survival proportion in the SpineCor sample, though was 0.08, while in the natural history cohort it was 0.34. The SpineCor treatment during pubertal growth spurt seems to lead to a worse outcome than observation only. The use of a simple biomechanical model explains that in the brace the compression forces exceed the lateral forces used for the corrective movement.

It is the most common form of leukemia in the western world (incidence 3-5/100 000). Elderly people are mainly affected, median age at diagnosis is around 70 years and there is a slight predominance in men. The etiology of the disease is unknown. The initial symptoms are nonspecific. Cervical lymphadenopathy and splenomegaly followed by general fatigue are seen most commonly. Other possible symptoms include night sweats, fever, loss of weight (so-called B symptoms) and frequent infections. Several patients develop autoimmune complications as autoimmune hemolytic anemia (AIHA) or immune thrombocytopenia (ITP). To confirm the diagnosis more than 5000 B-lymphocytes/µl need to be present. The expression of the typical surface markers CD5, CD19, and CD23 has to be confirmed by flow cytometry. Imaging studies as X-ray of the chest, ultrasound of the abdomen, or CT scan are used to assess the degree of lymphadenopathy or organomegaly. A bone marrow biopsy is not mandatory for the diagnosis. According to the European Binet staging system, CLL is divided into 3 stages (A, B and C). Patients in Binet stage A have 0 to 2 areas of node or organ enlargement with normal levels of hemoglobin and platelets. Binet stage B patients have 3 to 5 areas of node or organ enlargement and normal or slightly decreased levels of hemoglobin and platelets. Binet stage C patients have anemia (hemoglobin &lt; 10 g/dl) and/or thrombocytopenia (platelet counts &lt; 100 000/µl), with or without lymphadenopathy or organomegaly. As there is no survival benefit associated with early intervention, asymptomatic patients with early stage CLL (Binet stage A and B) are usually not treated but are followed on a \"watch and wait\" principle. Treatment indications include stage Binet C or signs of an active disease as rapidly progressive lymphadenopathy or organomegaly together with physical limitation, B symptoms that cannot be tolerated, rapidly deteriorating blood values, or rapidly increasing leukocyte counts. The patient's physical condition has major impact on the treatment decision.

Haematological and clinical features of this CD5- series were compared with those of 333 CD5+ B-CLL patients from the same institute. No significant differences were observed regarding peripheral blood (PB) and bone marrow (BM) lymphocytosis, Hb level, platelet count, incidence of adenomegaly, hepatomegaly or splenomegaly or diffuse BM pattern. Due to an absence of nodal enlargements or to general clinical condition, lymph node biopsy was performed in only three patients, while spleen histology was examined in two cases following splenectomy. All histological results confirmed the clinical diagnosis of CLL. The distribution of the CD5- subjects according to the different staging categories proposed by Rai, Binet and Mandelli was similar to that of CD5+ subjects. Ten patients received standard chemotherapy with Chlorambucil (CHL) and Prednisone (PDN). All achieved partial remission, although one of these patients later died of disease progression; 80 months after diagnosis. We conclude that rare cases of CD5- lymphocytosis fulfilling all criteria for B-CLL may occur.

Immunohistochemical staining and a molecular examination for p53 were carried out with specimens from the splenectomy. We found overexpression of the p53 protein in lymphoid cells and a point missense mutation in codon 280 at exon 8 that changed AGA (Arg) to AGT (Ser).

None of the two patients in immunological remission relapsed within a period of 13 and 33 months, whilst two of the six patients in CR with positive flow cytometry relapsed 3 and 6 months after achieving CR.

His disease was relapsed in June 1986, and the combination chemotherapy with mitoxantrone, etoposide and Ara-C was applied to him but failed to attain CR. Then, LVP protocol, the chemotherapy for ALL, was started and CR was achieved. The blasts at relapse had morphologically myeloid features, and expressed HLA-DR, CD2 and CD13 as well as at diagnosis. Cytogenetic studies at relapse showed some karyotype except gaining 12p- anomaly. Therefore, same blasts were considered to emerge at relapse.

Therefore, the splenectomy are usually needed to confirm the diagnosis, but the majority of patients could not accept such management, resulting in early difficult diagnosis. This study was purposed to explore the more prior way for diagnosis based flow cytometry (FCM). Six patients with suspected diagnosis of SMZL were used as research objects, 10 healthy bone marrow donors and 10 cases of chronic lymphocytic leukemia (CLL), 3 cases of hairy cell leukemia (HCL), 3 cases of lymphatic plasma cell lymphoma/Waldenströ's macroglobulinemia (LPL/WM) were selected as control. The immunophenotype of bone marrow cells were analyzed and compared by FCM using a panel of antibodies including CD45, CD5, CD10, CD19, CD20, CD22, CD23, CD25, CD103, CD11c, CD123, κ,λ, Cyclin D1, and combined with bone marrow cell morphology. The results indicated that 6 cases of suspected SMZL showed a large increase of lymphocytes and splenomegaly. Because absence of peripheral lymphadenopathy, 6 patients did not suffer from lymph node biopsy, only 1 patient underwent diagnostic splenectomy. The immunophenotypes of bone marrow in patients and controls were analyzed by FCM, as a result, except for the healthy donors, varying degrees of abnormal mature B cell clones were found in bone marrow of all patients, and the further differentiation from other B-cell tumors was performed through CD5, CD10 expression and combination with other B-cell phenotype. All 6 cases of SMZL patients expressed CD19(+) and CD20(+), but CD10 expression was negative, 4 patients expressed CD5(-), 2 patients expressed CD5(+). The expressions of CD23, CD38, ZAP-70, CD11c, CD103, CD123, Cyclin D1 were negative. The morphological examination of bone marrow cells showed velutinous abnormal lymphocytes. Combined with clinical characteristics, 6 patients were diagnosed as SMZL, 1 patient suffered from splenectomy because of concurrent hypersplenism, and this postoperative pathologic examination confirmed the patient with SMZL. Ten cases of CLL mainly expressed CD5, CD23; 3 cases of HCL had more typical morphology of \"hair like\" in addition to CD11c, CD103 and CD123 positive; 3 cases of LPL/WM had significantly increased light chain restriction expression, IgM, plasmacytoid lymphocytes.

In a retrospective analysis, among the 7 patients with PNH-AA syndrome, 5 had a partial response after the initial treatment. The FC on granulocytes is a useful method to diagnose and characterize PNH. This test is good for early detection of PNH clones in AA patients at initial diagnosis and in long term survivors. In both diseases it permits measuring the extent of the abnormal clone and its follow up. The extent of the defect is more related to haemolysis than the haematopoietic deficiency.

A combination of these cells is given the name minimal residual disease (MRD). Multicolor flow cytometry has recently attracted considerable interest as the most promising method for measuring the content of residual tumor blasts. This technique is based on the detection of the so-called leukemia-associated immunophenotype (LAIP), i.e., a tumor-specific combination of the expression of membrane and cytoplasmic markers. Flow cytometry may be successfully used to monitor MRD in 90-95% cases of acute lymphoblastic leukemia (ALL) and in 80-85% of patients with acute myelocytic leukemia. The sensitivity of flow cytometry, which is real for routine flow techniques, is a possibility of identifying one cell among 10(4)-10(5) cells. Multicolor flow cytometry (that involves the simultaneous analysis of the expression of a few markers) is the most reasonable tool for MRD monitoring. The monoclonal antibody panels recommended by different groups of investigators for MRD monitoring in B-lineage ALL include antibodies to the pan-B-cell antigen CD19, markers of different stages of differentiation of B-lineage precursors of CD10, CD34, and CD20 and leukemia-associated markers different for each panel, such as CD22, CD38, CD58, CD45, TdT, CD13, CD33. The hyperexpression of CD10, CD34, CD19, TdT, the decreased expression of CD38, CD45, CD22, CD19, the simultaneous expression of markers of different stages of differentiation of B lymphocytes, such as CD10 and CD20, and the lymphoblast coexpression of myeloid markers of CD13, CD33, CDS15 are the most frequently described immunophenotype aberrations in B-lineage ALL. The selection of combinations of markers for MRD monitoring in children with T-ALL is based on the simultaneous expression of combinations of the antigens characteristic for early stages of differentiation of normal T lymphocytes, namely TdT and cytoplasmic CD3. Some authors consider the use of CD99 versus TdT to be most appropriate. There is recent evidence that MRD-positive patients have a higher cumulative risk for recurrences as compared with those without residual blasts. Moreover, the longer the tumor cells are retained during therapy, the worse the prognosis is. Thus, for choice of the adequate intensity of antitumor therapy, it is necessary to qualitatively and quantitatively assess MRD by multicolor flow cytometry at different stages of therapy." }, { "id": "pubmed23n0749_1875", "title": "A case of chronic lymphocytic leukemia with massive ascites.", "score": 0.008928571428571428, "content": "An 81-year old woman with a history of chronic lymphocytic leukemia (CLL) was admitted with night sweats and abdominal distension.

Flow cytometry is one of the basic methods for evaluation of MRD in precursor B-lineage acute lymphoblastic leukemia (PBLALL). The so-called simplified three-color analysis using the combination of CD19/CD10/CD34 antibodies has been proposed to detect MRD in the midcourse of induction therapy. Four-to-nine-color is presently used to identify MRD. One hundred and thirty-four bone marrow samples taken at different stages of therapy in 55 children with PBLALL were examined to estimate the possibility of using the flow cytometry technique using the 3-color simplified approach to determining MRD. The results of the simplified and standard approaches were compared in the samples stained with 6-8 monoclonal antibodies in the combinations that always included CD19, Cd10 and CD34. The comparison revealed that MRD had been incorrectly identified by the simplified method in 8.0, 17.6, and 75.8% of the patients on therapy days 15, 36, and 85, respectively. In addition, the content of residual tumor cells with respect to the threshold values more frequently proposed to stratify patients was found to be incorrectly calculated in some true positive samples. Thus, when the simplified approach was applied using the results of MRD detection to stratify the patients into risk groups, 16.0, 27.4, and 81.8% of the samples would yield incorrect information on therapy days 15, 36, and 85, respectively. Thus, the simplified approach to identifying MRD is most applicable on day 15 of therapy; however, there may be mistakes in this point of observation. This method used on day 36 more frequently yields incorrect results and is inapplicable on day 85." } ] } } }

He was admitted to the intensive care unit and started on emergent hemodialysis. He was anemic and became gradually hypoxic, requiring supplemental oxygen. Computed tomography of the chest showed bilateral infiltrates. Antinuclear antibodies (ANA) were positive for centromere pattern with titer of 320. Antineutrophil cytoplasmic antibodies and antiglomerular basement membrane antibodies were negative. He was started on therapeutic plasmapheresis (TP) and captopril, which resulted in significant improvement of respiratory symptoms. The kidney biopsy revealed thrombotic microangiopathy. Anticentromere, anti-Scl-70, and antiribonucleic acid polymerase III antibodies, drawn after 4 sessions of TP, were not detected. CONCLUSIONS Here we report a rare case of ssSSc with renal crisis in a patient who presented with acute renal failure requiring hemodialysis and suspected pulmonary hemorrhage. Clinical improvement was achieved by TP and angiotensin-converting enzyme inhibitor. The diagnosis of ssSSc was difficult and required an ANA pattern and kidney biopsy." }, { "id": "pubmed23n0053_15137", "title": "[Spontaneous remission of dermatomyositis which developed one month after normal delivery].", "score": 0.0150650789255054, "content": "A case of dermatomyositis which developed one month after normal delivery and subsided spontaneously was reported. A 29-year-old woman gave birth to a healthy child. One month later, she noticed muscular pain and weakness of the upper extremities. On admission, there were diffuse edema of upper eyelids with heliotrope rash. The reddish skin rashes were observed on the extensor surfaces of the PIP and MP joints of fingers. Erythrocyte sedimentation rate was 29 mm/hr. The lactic dehydrogenase (LDH), SGOT, CK levels were 470 (normal 150 to 320 IU/l), 43 (normal 6 to 25 IU/l) and 317 (normal 21 to 110 IU/l) respectively. Autoantibodies to nuclear and cytoplasmic antigens were negative. Rheumatoid factor and anti-DNA antibody were negative. Thyroid function was normal. An electromyogram (EMG) demonstrated small amplitude short-duration polyphasic motor unit potentials. The muscle biopsy specimen from left upper arm showed degenerating muscle fibers and infiltration of inflammatory cells surrounding blood vessels. The skin biopsy revealed the presence of edema and perivascular infiltration of lymphocytes. Based on these clinical features and results of various diagnostic tests, a diagnosis of dermatomyositis was established. After the admission, muscle strength has improved dramatically and the CK returned to normal level without specific drug therapy. She has since been seen as an out patient, and complete remission lasted for two years up to date. Review of the literature disclosed that 13 cases of PM/DM which developed during pregnancy or postpartum have been reported including the present case. Detailed analysis showed that these patients were characterized by mild muscular diseases, rare occurrence of internal organ involvements and good response to steroid therapy.

This patient was diagnosed with systemic lupus erythematosus (SLE). After given hormones, hydroxychloroquine sulfate (HCQ), her symptom relieved soon. The patient stopped her pills 1 year ago. One month ago, she had chest tightness, increased urine foam, and suffered from oliguria. Her admission medical examination: blood pressure (BP) 130/80 mmHg, conjunctiva pale, and lower lung breath sounds reduced. There was no tenderness, rebound pain and abdominal muscle tension in the abdomen. Liver and spleen rib inferior, mobile dullness negative, and lower extremity edema.

Admission diagnosis: SLE lupus nephritis, anemia, pleural effusion, and hypoproteinemia. We treated her with methylprednisolone 1 000 mg×3 d, late to 48 mg/d and cyclophosphamide 1.0 g, HCQ 0.2 g bid, gamma globulin 10 g×5 d. Day 2 of treatment, this patient developed acute right upper quadrant pain, not accompanied by nausea, vomiting, blood stool and diarrhea. Antipyretic antispasmodic treatment was invalid, after the morning to ease their own abdominal pain. Day 4 of treatment, daytime blood HGB 77 g/L. Bilateral renal vascular ultrasound: bilateral renal artery blood flow velocity was reduced. The abdominal pain of the above symptoms recurred at night, BP was 120/80 mmHg, and no positive signs were found on abdominal examination. No abnormality was found in the vertical abdominal plain film. Blood routine examination: HGB 53 g/L, Plasma D dimer 2 515 μg/L, amylase in hematuria was normal, the stool occult blood was negative. Abdominal computed tomography (CT): normal structure of right adrenal gland disappeared, irregular mass shadow could be seen in adrenal region, CT value was about 50 HU. Morphological density of left adrenal gland was not abnormal. The retroperitoneum descended along the inferior vena cava to the right iliac blood vessel and showed a bolus shadow. The density of some segments increased. The lesion involved the right renal periphery and reached the left side of abdominal aorta. Most lesions surrounded the inferior vena cava, the right renal vein and part of the small intestine. The boundary between the upper lesion and the vena cava was unclear. Iodinecontaining contrast agent was taken orally. No sign of contrast agent overflowing was found in the abdominal cavity. Hematoma and exudative changes were considered in retroperitoneum. CONCLUSION of contrast-enhanced ultrasound of blood vessels: The retroperitoneal inferior vena cava (volume 3.5 cm×3.5 cm×1.5 cm) was hypoechoic and had no blood flow lesion. The adrenal gland had a high possibility of origin. Left renal vein thrombosis extended to inferior vena cava. According to the above data, it was analyzed that the cause of retroperitoneal hematoma of the patient was left adrenal vein thrombosis caused by hypercoagulable state, which led to vascular rupture and hemorrhage caused by increased vascular pressure in adrenal gland. Therefore, on the basis of continuing to actively treat the primary disease, and on the basis of dynamic observation of no active hemorrhage for 3 days, the anticoagulant therapy was continued with 10 mg/d of apixaban. Clinical symptoms were gradually eased, HGB did not decrease. Two weeks later, the ultrasonic examination showed that the irregular cluster hypoechoic range behind the inferior vena cava was significantly smaller than that before (1.8 cm×1.2 cm×0.7 cm). Abdominal CT examination after 1 month showed that there was no abnormal morphological density of bilateral adrenal glands and basic absorption of retroperitoneal exudation. Adrenal hemorrhage is uncommon. SLE with adrenal hemorrhage is rarer. In SLE patients, especially those complicated with APS, if abdominal pain accompanied by HGB decrease occurs, except after gastrointestinal hemorrhage, the possibility of adrenal hemorrhage should be warned." }, { "id": "pubmed23n0320_15745", "title": "[A case of scleroderma renal crisis with massive pericardial effusion and positivity on antiphospholipid antibody test].", "score": 0.014266435319066899, "content": "A 47-year-old woman was admitted to our hospital for evaluation of general fatigue and dyspnea.

The volume of pericardial effusion amounted to more than 2000 ml. Post operative malignant hypertension persisted. Laboratory data showed thrombocytopenia, hemolytic anemia, and acute renal failure. We diagnosed scleroderma renal crisis (SRC) associated with antiphospholipid syndrome. Following the initiation of angiotensin converting enzyme inhibitor (ACE-I) combined with calcium antagonist and alpha-one blocker, her blood pressure and PRA decreased. She also had been treated with aspirin 81 mg daily. These therapies were effective in recovering the platelet count and stopped the progression of anemia and renal failure.

Cutaneous involvement, either alone or in association with other systemic illnesses, is one of its most common manifestations (1). Dermatologic disorders like malar and discoid rashes are quite suggestive of SLE. However, the occurrence of non-specific skin lesions like erythema multiforme (EM) in patients with SLE (Rowell syndrome) can rarely occur (1). In such patients, a diagnosis of SLE may be missed or delayed in the absence of other overt clinical features of lupus. Herein we report a case of recurring EM-like eruptions as the cardinal cutaneous manifestation of previously undiagnosed, active SLE in a young Nigerian woman. A 26-year-old Nigerian woman presented with a three-day history of non-pruritic, generalized, and target-like, erythematous annular patches and plaques which mostly affected the trunk. A few lesions had presented with crusting and erosions at the time of examination (Figure 1). Associated symptoms included oral painful ulcers, low grade fever, and malaise. The patient had no other systemic symptoms and her prior drug history was not remarkable. Her erythrocyte sedimentation rate (ESR) was 66 mm/hour using the Westergren method. Screening for HIV and hepatitis B and C was negative. Herpes simplex, cytomegalovirus, and Epstein Barr viruses could not be screened for. Other baseline investigations (complete blood count, electrolytes, urea and creatinine as well as urinalysis) were within normal limits. The patient was managed as a case of EM of an unidentified inciting agent and her symptoms resolved with supportive care and antibiotics. However, she developed a recurrence about 5 weeks later, with more extensive and coalescent skin lesions (Figure 2). Additionally, there was a new onset of alopecia and pain in the small joints of the hands as well as both knees and ankles. At this time, the patient's ESR had gone up to 112 mm/h and she had developed significant proteinuria, with a protein creatinine ratio of 1.3 g/g (reference &lt;0.5 g/g). Her antinuclear antibody (ANA) titer was high (1:320) with a speckled pattern. Anti-Smith antibody was also positive. A renal biopsy was declined. A tentative diagnosis of Rowell syndrome was made. The patient was started on high-dose steroids and hydroxychloroquine 200 mg twice daily. Subsequent care included the use of mycophenolate mofetil 1 g twice daily for 6 months. This was then changed to azathioprine at 50 mg twice daily. Follow-up after 6 months showed sustained clearance of skin lesions, resolution of fever and joint pains, as well as improvement in the renal profile, with a urine protein-creatinine ratio of 0.77 g/g. The presence of systemic lupus erythematosus, EM-like lesions, and a speckled pattern of antinuclear antibody in our patient fulfils the revised diagnostic criteria for RS put forward by Zeitouni et al. at the turn of the twenty-first century (2). Considering the rarity of EM-like lesions in SLE and the possibility of constitutional symptoms in EM, a diagnosis of RS may be readily overlooked in patients like the one described, whose major cutaneous manifestation of severe active SLE was EM-like lesions. In contrast to classic EM, where skin lesions are concentrated in the extremities, a predominant truncal distribution of EM-like lesions as found in our patient may favor a clinical consideration of RS (3). However, some authors have challenged the existence of Rowell syndrome as a distinct clinical laboratory entity. Arguments put forward in this regard include the fact that none of the immunological markers that have been described in RS are specific to any disorder. Additionally, the annular polycyclic dermatosis seen in sub-acute cutaneous lupus erythematosus (SCLE) can be difficult to clinically and histologically differentiate from EM (4,5). Patients with SLE also have a higher likelihood of developing adverse drug reactions (6). The inherent complexity of SLE may make for delayed and oftentimes difficult diagnosis, especially in a country where immunologic tests are expensive and rheumatologists are scarce. When patients do occasionally present with recurrences of skin lesions in the spectrum of EM, Steven-Johnson syndrome, and toxic epidermal necrolysis in the absence of a definite inciting agent, undiagnosed lupus may indeed be present in some of these individuals and should be considered in the differential diagnosis. In conclusion, while it is very rare, SLE may present first with recurrent episodes of EM-like rash. Despite the various possibilities which underlie their association, prompt identification and treatment of SLE in patients presenting with EM is important to prevent death or irreversible organ damage." }, { "id": "pubmed23n0913_15886", "title": "Crescentic glomerular nephritis associated with rheumatoid arthritis: a case report.", "score": 0.009900990099009901, "content": "Rheumatoid arthritis is a systemic disorder where clinically significant renal involvement is relatively common.

We describe 4 patients with paraneoplastic scleroderma who were treated at the I. Department of Dermatovenereology, St. Anna Hospital, during the period between 2004 and 2014. The patients were diagnosed with cholangiogenic carcinoma, endometrial carcinoma, prostatic adenocarcinoma, and adenoma of the suprarenal gland. In the case of concurrent scleroderma and tumor, four situations may occur: they can develop independently of each other; scleroderma may be induced by the tumor; the tumor can develop in the scleroderma; or the tumor can be induced by immunosuppressive therapy. Sclerotization of the skin was described in association with lung cancer, carcinoid, plasma cell dyscrasia, cancer of the ovary, cervix, breast, esophagus, stomach, nasopharynx, melanoma, and sarcoma (1,2,5,7,10). Symptoms may be induced by substances secreted by the tumor (hormones, cytokines, etc.) (9). Tumorous cells further induce cytotoxic and autoantibody response. Scleroderma is characterized by immunological dysregulation, vasculopathy, and hyperproduction of the extracellular matrix by activated fibroblasts. Endothelial, inflammatory, and mesenchymal cells produce cytokines, chemokines, and growth factors e.g. Interleukin-1 (IL1), Interleukin-6 (IL6), tumor necrosis factor alpha (TNF α), collagen alpha 1, connective tissue growth factor (CTGF) (3), and basic fibroblast growth factor (bFGF). This factor is also produced by lung cancer cells (4). The clinical picture of scleroderma and paraneoplastic scleroderma is similar. Diffuse thickening of the skin and/or sclerodermatous plaques can be seen. The histological picture is consistent with scleroderma. Capillaroscopy changes, antinuclear antibodies (ANA), sclerodactyly, and Raynaud phenomenon suggest the diagnosis of systemic scleroderma (SS) (4). Our patients did not fulfill enough of the criteria for SS. Both diffuse and localized scleroderma was seen in 3 patients and generalized localized scleroderma in one case. All patients had a histological picture consistent with scleroderma, negative ANA and ENA antibodies (Table 1, Figure 1). A 66-year-old woman presented with a 10 months history of sclerodermatous plaques on her neck, trunk, and upper and lower extremities. The skin on her breasts and cheeks was diffusely indurated. Examination showed thrombocytopenia, elevated transaminases, Cancer antigen 19-9 (Ca 19-9), thyroid stimulating hormone (TSH), and anti-thyroid peroxidase antibodies, dysmotility of the lower part of esophagus, hepatosplenomegaly, cholecystolithiasis, and benign polyps of colon. She was given prednisone 40 mg/day but did not return for follow up. After 6 months she was diagnosed with cholangiogenic carcinoma with metastatic disease and died shortly afterwards. A 74-year-old woman had localized scleroderma on the trunk for three years. She was treated with procaine penicillin for positive borrelia Immunoglobulin M (IgM) antibodies. Her condition worsened suddenly with confluent scleroderma plaques on her trunk, extremities, and genital region, and vasoneurosis on her lower extremities; she was started on prednisone 35 mg/day. Examination revealed endometrial cancer. The patient underwent a hysterectomy, adnexectomy, and radiotherapy with curative effect. Scleroderma patches softened with residual hyperpigmentation, and prednisone was stopped two years later. A 80-year-old man had a month-long history of diffuse thickening and toughening of the skin on the forearms and lower legs and scleroderma patches on the thighs and shins. Examination revealed prostate adenocarcinoma, and therapy with antiandrogen bicalutamide and prednisone 15 mg/day was started. Two years after the diagnosis he continues with bicalutamide treatment, prednisone 5 mg q.a.d. and has residual toughening of the skin on his lower legs. A 62-year-old woman with seronegative rheumatoid arthritis presented with diffusely tough skin on her extremities and trunk, present for 2 months. Examination revealed cervicitis with a benign endometric polyp, cholecystolithiasis, borderline pulmonary hypertension, and a hormonally inactive suprarenal adenoma. She was given prednisone 40 mg/day and penicillamine with effect. In the 3rd year of therapy she has residual induration of her lower legs and a scleroderma plaque in the lumbar region. She is monitored for her suprarenal adenoma. Two patients had scleroderma at the same time as a malignant tumor; in one patient the localized scleroderma worsened rapidly at the time of the tumor diagnosis, and in one patient a clinically silent adenoma was found. Adrenal tissue can secrete molecules such as serotonine or bFGF involved in fibroplasia (3,6). One patient died of a metastatic disease, two patients after the successful treatment of the tumor, and the patient with suprarenal adenoma experienced softening of the skin and regression of scleroderma. Although paraneoplastic scleroderma is often classified as a pseudoscleroderma, we regard neoplasia as a distinct triggering impulse for scleroderma. Recently, an association between RNA polymerase I/III antibodies in systemic scleroderma and cancer was suggested (8). Such studies may confirm the true link between scleroderma and malignancy. These patients are characterized by older age, sudden onset, diffuse thickening of the skin, and/or generalized morphea with a concurrent neoplastic process. In the case of a successful tumor treatment, skin changes regress.

Plasma renin activity was 13.3 ng/ml/hr. Renal angiography showed stenoses and irregularities in the peripheral branches of renal arteries bilaterally. These findings led to a diagnosis of renovascular hypertension due to vasculitis. Her blood pressure was controlled with an angiotensin-converting enzyme inhibitor and a calcium antagonist. Vasculitis associated with chronic supportive lung disease has occasionally been reported, which suggests a casual relation between chronic respiratory infection and ANCA-related vasculitis.

It is possible that long-standing, untreated disease may result in esophageal remodeling, leading to strictures, Schatzki ring and, eventually, achalasia. History The first case of eosinophilic esophagitis was reported in 1978. In the early 1990s, it became recognized as a distinct disease.

It is characterized by intense infiltration of eosinophilic leukocytes in the esophageal mucosa, without involvement of other sections of the alimentary canal. Over the past year, following the performance of endoscopies and biopsies, our service identified nine patients who were diagnosed with suffering from this disorder. Each patient sought medical help for episodes of long-term, self-limited dysphagia or food impaction in the alimentary canal. Endoscopy revealed esophageal stenosis in the form of simultaneous contraction rings or regular stenosis. In six cases, the manometric study showed a nonspecific motor disorder of severe intensity affecting the esophageal body, and another patient had a disorder characterized by the presence of simultaneous waves and secondary peristaltic waves in the three thirds of the organ. These disorders are presumably due to eosinophilic infiltration of the muscular layer or ganglionar cells of the esophagus, and account for symptoms in these patients. Although the etiopathogenesis of this illness is uncertain, it is clearly an immunoallergic manifestation. As the number of diagnosed cases is on the increase, eosinophilic esophagitis is in adults a specific entity within the differential diagnosis of dysphagia in young males with a history of allergies. Eosiniphilic esophagitis responds in a different number of ways to therapies used. We successfully used fluticasone propionate, a synthetic corticoid applied topically, which proved to be efficient in the treatment of this illness by acting on the pathophysiological basis of the process. It does not have any adverse effects, thus offering advantages over other therapies such as systematic corticoids or endoscopic dilations." }, { "id": "pubmed23n0490_13884", "title": "Eosinophilic esophagitis in adults: an emerging problem with unique esophageal features.", "score": 0.015176419022572867, "content": "Eosinophilic esophagitis is an inflammatory condition in which there is dense eosinophilic infiltration of the surface lining of the esophagus. Reports of eosinophilic esophagitis pertain almost exclusively to pediatric populations. However, eosinophilic esophagitis is emerging as a clinical affliction of adults. This report describes the clinical and endoscopic findings of eosinophilic esophagitis in the largest cohort of adult patients reported to date. Twenty-nine patients (21 men, 8 women; mean age 35 years) with documented eosinophilic esophagitis (&gt;/=15 eosinophils per high-power field in biopsy specimens) and a significant history of chronic dysphagia for solid food (24 patients) were evaluated clinically and endoscopically during a 3-year period (1999-2002). Fourteen patients (48%) had a history of asthma, environmental allergy, or atopy. In a subset of 15 patients, the diagnostic accuracy of endoscopy was compared with that of barium contrast esophagography. Twenty-seven patients (93%) had abnormal endoscopic findings; 25 (86%) had unique esophageal structural changes, associated with a preserved mucosal surface, that were highly atypical for acid reflux injury. Structural alterations seen in adult patients with eosinophilic esophagitis may occur in combination or as a primary characteristic, e.g., uniform small-caliber esophagus, single or multiple corrugations (rings), proximal esophageal stenosis, or 1 to 2 mm whitish vesicles scattered over the mucosal surface. Barium contrast radiography combined with swallow of a barium-coated marshmallow identified 10 (67%) of the primary features observed endoscopically in 15 patients. However, radiography failed to detect other features noted at endoscopy (e.g., only 3/6 patients with proximal stenosis, 5/9 patients with concentric rings and none of 4 patients with small caliber esophagus). Eight of the 29 patients (20%) had a history of chronic heartburn. Twelve patients had been treated with a proton pump inhibitor and only 3 reported some improvement in the severity of dysphagia. Relatively young age, a history of chronic dysphagia for solid food, and endoscopic detection of unique structural alterations atypical for GERD in an adult patient should prompt a suspicion of EE and subsequent biopsy confirmation. Acid reflux appears to have a secondary role in eosinophilic esophagitis. In an uncontrolled comparison, endoscopy was superior to barium contrast radiography for the diagnosis of eosinophilic esophagitis.

However, little is known about the pathogenesis of the disease, as patients are seldom suspected and rarely diagnosed with lymphocytic esophagitis. Here, we present a rare case of lymphocytic esophagitis in a patient with multiple allergies and suspected eosinophilic esophagitis. A 28-year-old woman with polyvalent sensitization to food and inhalant allergens presented with intermittent dysphagia, a sensation of a foreign body in the throat, itchiness of the oral cavity after ingesting certain foods, heartburn, and prolonged chewing time. A skin prick test showed positive results for birch-tree, alder, hazel, and rye pollen, as well as house dust mites. Apart from obesity (BMI 30 kg/m<sup2</sup), multiple pustules and excoriations on the skin, her physical examination was insignificant. Esophagogastroduodenoscopy (EGD) was performed revealing full-length but discrete trachealization of the esophagus. A barium swallow test showed slowing of esophageal peristalsis in the recumbent position. No esophageal pathology was observed. A histopathological analysis of mucosal samples revealed slight hyperplasia of the basal layer of the esophagus, and the stomach showed changes typical of chronic gastritis. In summary, this clinical case illustrates that lymphocytic esophagitis, as a newly recognized entity, should be considered in the differential diagnosis of chronic dysphagia.

The patient was afebrile, hypertensive at 172/114, and found to have a normal heart rate of 88 bpm and a respiration rate of 18 breaths per minute. An esophagogastroduodenoscopy (EGD) was performed, which revealed a fexofenadine-pseudoephedrine capsule at 23 cm from the incisors along with a superficial ulceration at the corresponding level in the esophagus. The foreign body was successfully removed using raptor forceps. Further visualization demonstrated trachealization of the esophagus and furrowing and severe narrowing (&lt; 10mm), which raised suspicion for EoE. Proximal biopsy indicated 16 intraepithelial eosinophils per HPF within the squamous epithelium, likely compatible with EoE. The patient tolerated the procedure well and was discharged on an eight-week course of proton-pump inhibitors. EoE is defined as an immune-mediated esophageal disease characterized histologically by eosinophil-predominant inflammation.

All patients with endoscopically diagnosed SRs, defined as thin, symmetrical, mucosal structures located at the esophagogastric junction, were prospectively registered. Additional endoscopic findings, clinical information and histopathological findings with a focus on esophageal eosinophilia (≥ 20 eosinophils/high power field) were recorded.

Gastroesophageal reflux disease was excluded by proton pump inhibitor treatment prior to endoscopy. The presence of ≥ 20 eosinophils/hpf in esophageal biopsies in patients that did not fulfil the criteria of EoE was defined as esophageal hypereosinophilia.

The patient was diagnosed with TS at the age of 4 years, upon a diagnostic work-up for dysmorphic features. Chromosome analysis revealed a mosaic karyotype (45X0/47XXX).

A physical examination revealed a Tanner stage III for breast and Tanner stage III for pubic hair development. Height and weight were within the normal range for age. Psychological evaluation showed moderate global developmental delay, together with emotional and social immaturity and reading difficulties. The growth rate was accelerated. Her bone age was 10 years. Pelvic ultrasound demonstrated increased size for age of both the uterus and the ovaries, with bilateral ovarian follicles. GnRH stimulation test revealed pubertal response of gonadotropins (peak LH 22.5 mIU/ml). MRI of the brain was normal. These clinical, radiologic and laboratory findings were consistent with a diagnosis of idiopathic central precocious puberty; therefore, GnRH analog therapy was started, in order to slow pubertal progression and to preserve adult stature. Furthermore, GH treatment was added to further improve adult height. Our case highlights the possibility of precocious puberty as an atypical clinical feature of TS. Thus, precocious puberty may occur in TS girls when a dosage compensation by the cell line with more than two X chromosomes allows normal ovarian function.

The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising &lt;1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with \"playing\" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are \"high-risk\" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a \"hair ball\" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

We examined 48 patients (26 males) with certain idiopathic GHD diagnosed at 4.8 +/- 0.7 yr. The symptoms that led to the diagnosis of GHD were low growth rate (33 cases), hypoglycemia (12 cases), microphallus (1 case) and in 2 cases the GHD was diagnosed from magnetic resonance imaging (MRI) performed for delayed mental development (1 case), or congenital blindness (1 case). The 2 other cases were diagnosed from routine GH evaluation performed at birth because of idiopathic GHD in siblings. Thirteen had congenital malformation. Twenty three cases (48%) had features suggesting that the GHD was of antenatal origin. Six of them were born by breech delivery. Twenty one cases (44%) had features suggesting a hypothalamic origin. The decrease in growth rate occurred before 0.5 year in 21 (55%), before 1 year in 27 (71%) and before 2 years in 30 (79%): 8 patients (21%) maintained a normal growth rate after this age. Among these 8 patients, 5 had signs suggesting an antenatal origin and 4 had severe episodes of hypoglycemia from birth. The mean GH peak after the pharmacological stimulation test was 3.6 +/- 0.5 micrograms/l. The mean plasma insulin-like growth factor 1 (IGFI) was 0.1 +/- 0.02 U/ml. The GH deficiency was associated with deficiencies of thyrotropin in 26 (54%) and of adrenocorticotrophic hormone in 17 (35%) patients. Among the 15 patients of pubertal age, 9 (60%) had gonadotrophin deficiency. No patient had diabetes insipidus. The MRI showed pituitary stalk interruption syndrome in 39 patients and normal pituitary anatomy in 6 patients. GH treatment reduced the difference between target and actual heights from 3.5 SD (before) to I SD (after 3 years) in the 39 more recently seen patients given 0.5-0.6 U/kg/w GH in 6 or 7 weekly injections. Height gain during the first year and cumulative height gain over 3 years (SD) was correlated negatively with height (SD) at the start of treatment (p &lt; 0.01).

It was believed that the mass effect of the arachnoid cyst upon the hypothalamus was, at least in part, responsible for development of precocious puberty. The role of surgical decompression of the cyst was also discussed. A one-year-old girl was admitted to the hospital for evaluation of genital bleeding which had persisted on and off for two months. The height, 80cm, and the weight, 12.4kg, exceeded by far the two standard deviations from the mean level of the normal population.

The pubertal features at the time of the original diagnosis might be explained by: 1. the direct action of elevated TRH on gonadotropes to stimulate gonadotropin secretion and on lactotrophes to stimulate PRL secretion, and 2. TSH action on LH and mostly FSH receptors (homologous to TSH receptors) in the ovary, stimulating the secretion of estradiol." }, { "id": "pubmed23n0243_2715", "title": "Growth hormone treatment in children with craniopharyngioma: final growth status.", "score": 0.009615384615384616, "content": "Twenty-seven out of thirty craniopharyngioma patients treated with human growth hormone (hGH) for 2 years or more (average 4.5 years) reached final adult heights above the population third centile, though none was above the fiftieth centile.

It carries a good prognosis with late but normal puberty and late catch-up growth leading to normal adult height. It manifests itself long before puberty by short stature and retarded bone age. True endocrine defects with permanent hypogonadism (hypothalamic-pituitary deficiency of the gonadotropinds and primary gonadal failure) are rare. Differential diagnosis before puberty is not always possible on clinical grounds alone. The most useful laboratory test consists of the LH-RH test. The i.v. injection of the recently introduced hypothalamic LH-releasing hormone, LH-RH, is followed by an age-dependent increase of the plasma gonadotropinds LH and FSH. This test allows differentiation, before puberty, between constitutional delay of growth and adolescence with a normal response for bone age, true hypothalamic-pituitary insufficiency with no response, and primary gonadal failure with an increased response. True hypogonadism requires permanent sex hormone replacement therapy.

It is known that growth hormone deficiency during childhood may delay pubertal development, but there is limited data about primary amenorrhea in GH-deficient girls with sufficient stimulated gonadotropin levels.Methods: Case series.Results: In the evaluation of primary amenorrhea and delayed puberty, 3 cases of adolescent females aged 17-19 years were identified as isolated GH-deficiency. Among the 3 patients, 2 had history of intracranial surgery due to hydrocephalus (shunt operation) or prolactin-secreting pituitary macro-adenoma (transphenoidal surgery, one year before). 17-year-old patient with shunted hydrocephalus and 19-year-old patient with primary amenorrhea showed short statue (&lt; 5%) and delayed bone maturation.

We report a novel mutation in the CYP19 gene in a sister and brother. The 28-yr-old XX proband, followed since infancy, exhibited the cardinal features of the aromatase deficiency syndrome as recently defined. She had nonadrenal female pseudohermaphrodism at birth and underwent repair of the external genitalia, including a clitorectomy. At the age of puberty, she developed progressive signs of virilization, pubertal failure with no signs of estrogen action, hypergonadotropic hypogonadism, polycystic ovaries on pelvic sonography, and tall stature. The basal concentrations of plasma testosterone, androstenedione, and 17-hydroxyprogesterone were elevated, whereas plasma estradiol was low. Cyst fluid from the polycystic ovaries had a strikingly abnormal ratio of androstenedione and testosterone to estradiol and estrone. Hormone replacement therapy led to breast development, menses, resolution of ovarian cysts, and suppression of the elevated FSH and LH values. Her adult height is 177.6 cm (+2.5 SD). Her only sibling, an XY male, was studied at 24 yr of age. During both pregnancies, the mother exhibited signs of progressive virilization that regressed postpartum. The height of the brother was 204 cm (+3.7 SD) with eunuchoid skeletal proportions, and the weight was 135.1 kg (+2.1 SD). He was sexually fully mature and had macroorchidism.

It took the patient and his family only 1.5 h to familiarize themselves with the use of the pump. They were trained in its use in our outpatient pain department. For pain control both the variable continuous infusion and the extra injection doses could be administered by the way of the syringe driver. The patient was given a stock of 120 ampoules of morphine for further treatment at home. For optimal pain control he decided to raise the daily dose of opioid infusion from the initial 60 mg to 240 mg morphine within 48 h. In this way, PCAO-besides rapid titration of the opioid dose to achieve analgesia-allows the use of opioids controlled by the patient himself. In the present case this procedure was also important when an outpatient radiation therapy became urgently necessary to prevent a fracture of the spine because of metastasis. The pain control by the patient himself was the main factor to get free of pain during the transport to the hospital. Even positioning for radiation was possible without pain. When he received outpatient radiation therapy the patient needed extra injection doses of up to 360 mg morphine a day. The PCAO procedure by continuous subcutaneous infusion with opiates is a safe and efficient method of pain management for outpatient patients suffering from severe cancer pain and intractable nausea in the terminal phase. Its validity has also been proven especially for radiation treatment of bone metastases." }, { "id": "wiki20220301en352_34206", "title": "Neutron capture therapy of cancer", "score": 0.009345794392523364, "content": "was well tolerated by the 30 patients who were enrolled in this study.

She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

It represents the acquired megakaryocytic thrombocytopenia with the shortened life of platelets because of immunologic damage (antibodies absorbed by platelets). In the case of this acquired hemorrhagic disorder, in spite of compensatory increased function of the bone marrow, there is a reduced number of platelets because of their increased destruction by the reticuloendothelial system (destructive thrombocytopenia). There are three forms of ITP: acute, chronic and intermittent. The acute form occurs in 80-90% of cases with bleeding episodes lasting a few days or weeks, but no longer than 6 months. The chronic form occurs in 10-15% of children, while the rarest-intermittent form is characterized by periods of normalization in regard to the number of platelets but also with relapse in intervals of 1-3 months. The disease is caused by an immunological disorder in the sense of an imbalanced immune response. Immunologic damages of platelets cause shortening of the opsonized platelets life span. The most frequent platelet opsonins are the immumoglobulin G (IgG) antibodies directed at the platelet membrane in the form of autoantibodies, alloantibodies or possibly absorbed antigen caused by microorganism infection or drug intake. It is typical for the phenomenon of bleeding that it starts suddenly and without any other sign of illness. The most frequent acute form appears between the second and fourth year, and is characterized by seasonal occurrence usually after acute viral infections. Children older than 10 years of age, like adults, often have the chronic form associated with other immunologic disorders. The disease affects girls more often than boys (about three times more often) with moderate and constant increase of antiplatelet antibodies. Hemorrhagic manifestations include: petechiae, purpura, epistaxis, gastrointestinal and genitourinary bleeding. They depend on the grade of thrombocytopenia, although there is no strict correlation between the number of platelets and volume of bleeding. Low mortality of the acute ITP is almost exclusively due to intracranial hemorrhage. LABORATORY STUDIES: Thrombocytopenia represents a decrease in the number of blood platelets being a basic abnormality of the blood count. The half-life of platelets in ITP is shortened. Detection of antiplatelet antibodies is connected with technical difficulties, so they are established in about 30% of cases. Bleeding time is prolonged and so is the coagulum retraction which may be completely missed. The Rumpel-Leede test is positive. Clinical differentiation of drug-induced thrombocytopenia is not possible. However, other differential diagnostic possibilities are thrombotic-thrombocytopenic purpura and hemolytic-uremic syndrome. A child with aplastic anemia or acute leukemia, beside thrombocytopenia, has a characteristic finding of white and red blood cell count. Thrombocytopenia with absent radii syndrome is associated with skeletal system abnormalities. New knowledge about the role of the immune system in ITP determines the modern therapeutic modalities. In cases of acute ITP in children, there are two therapeutic options or therapies of choice: corticosteroids and high doses of intravenous immunoglobulin. Immunosupressive therapy means anti Rh(D) immunoglobulin, cyclosporine, cytostatics, danazol, loaded platelets. In cases of distinctive hemorrhagic syndrome there are also indications for platelet transfusion. Nowadays splenectomy is more restricted, because one third of cases is unsuccessful, whereas plasmapheresis is rarely used in children because of possible complications. ITP is the most frequent hemorrhagic disease in children. The disease is basically caused by an immunologic disorder with platelet destruction due to increased immunoglobulin on their membrane.

The frequency of antiglycoprotein (GP) IIb/IIIa antibody-producing B cells, the presence of platelet-associated and plasma anti-GPIIb/IIIa antibodies, the percentage of reticulated platelets, and the plasma thrombopoietin level were examined at the first visit. The final diagnosis was based on the clinical history, physical examination, complete blood test, bone marrow findings, and the clinical course at last observation. Forty-six patients were diagnosed as having ITP and 16 as having another disorder, including myelodysplastic syndrome, aplastic anemia, amegakaryocytic thrombocytopenia, and reduced platelet production, with or without other cytopenias, and without dysplasia or evidence for destruction. Six initial laboratory findings discriminated ITP from other diagnoses: the absence of anemia, absence of leukocytopenia, increased frequency of anti-GPIIb/IIIa antibody-producing B cells, increased platelet-associated anti-GPIIb/IIIa antibodies, elevated percentage of reticulated platelets, and a normal or slightly increased plasma thrombopoietin level. Three or more of these ITP-associated findings were found at presentation in 44 patients (96%) with thrombocytopenia later diagnosed as ITP, compared with only 1 patient (6%) whose disorder was non-ITP.

Eighty-six patients with isolated thrombocytopenia (i.e., normal white blood cell count, hemoglobin, peripheral smear and clotting studies) were studied. The bone marrow was consistent with ITP in 82 patients, (i.e., normal or increased megakaryocytes and other hemopoietic lineages normal.)

Without platelets to form the platelet plug, which is the first step of hemostasis, the patient becomes more susceptible to bleeding. Most patients with ITP only have minor bleeds, such as nosebleeds or conjunctival bleeds. However, these patients are at risk of severe bleeds, and that risk helps guide management. ITP tends to affect children around five years old or older adults. In children, ITP typically presents with a sudden onset, usually following a microbial illness and is brief. In adults, it typically presents with insidious onset and is a chronic condition. In both patient populations, there must be a high index of suspicion, and ITP is usually a diagnosis of exclusion. A CBC and peripheral blood smear are typically performed in the initial evaluation. In adults, it is essential to rule out ITP secondary to other autoimmune diseases, so an anti-nuclear antibody (ANA) and autoantibodies specific for other conditions may be tested as well.

Stepwise narrated video demonstration of the sonographic evaluation for endometriosis in routine pelvic ultrasound following the recommended sonographic approach published in the 2016 consensus paper by the International Deep Endometriosis Analysis (IDEA) group [1]. Endometriosis is a common and often debilitating gynecological disorder that affects 5-10% of women [2]. The prevalence is even higher among women with symptoms of endometriosis [2], which include chronic pelvic pain, acquired dysmenorrhea, dyspareunia, dyschezia, menorrhagia, abnormal bleeding, and infertility. Approximately 80% of women who have endometriosis have superficial lesions, whereas 20% have deep infiltrating endometriosis (DIE; [3]). Laparoscopy is the gold standard for diagnosing endometriosis, because it allows the diagnosis of all forms of endometriosis and often immediate removal of superficial endometriosis. The removal of DIE is considerably more complicated and usually cannot be completed unless it was diagnosed preoperatively. The technique to diagnose DIE with transvaginal ultrasound (TVUS) was first described in detail in 2009 [4]. Since then, the accuracy of TVUS for the prediction of DIE has been well established in the literature [5-7]. TVUS is widely used as a first-line investigation for women with gynecological symptoms. The inclusion of an assessment for endometriosis in the routine pelvic ultrasound allows earlier diagnosis and better surgical outcomes for all women with DIE. The evaluation for endometriosis in routine pelvic ultrasound based on the IDEA consensus promotes a 4-step dynamic ultrasound approach [1]: (1) routine evaluation of uterus and adnexa with particular attention for sonographic signs of adenomyosis and the presence or absence of endometriomas; (2) evaluation of transvaginal sonographic 'soft markers' such as site-specific tenderness and ovarian mobility; (3) assessment of status of pouch of Douglas using the real-time ultrasound-based \"sliding sign;\" and (4) assessment of DIE nodules in the anterior and posterior compartments, which involves assessment of the bladder, vaginal vault, uterosacral ligaments, and bowel, including rectum, rectosigmoid junction, and sigmoid colon. Because 5-10% of women with DIE also have ureteric endometriosis, it is useful to assess the kidneys. Silent hydronephrosis is easily identified in 50-60% of patients with ureteric involvement. Although it is possible to identify DIE involving the ureters more directly, this requires more advanced skills, and further studies are still needed to better define the accuracy of ureteric DIE detection by TVUS [8-10]. Traditionally, only pathologies of the uterus and ovaries are assessed during a routine pelvic ultrasound. Here we demonstrate that the routine ultrasound examination can easily be extended beyond the uterus and ovaries into the posterior and anterior pelvic compartments to evaluate structural mobility and to look for deep infiltrating endometriotic nodules, wherewith women suffering from DIE can benefit from a preoperative diagnosis and subsequently, a single, well-planned procedure in the hands of a well-prepared team." }, { "id": "Gynecology_Novak_91", "title": "Gynecology_Novak", "score": 0.010102776320646578, "content": "Adolescent Patients A pelvic examination may be less revealing in an adolescent than in an older woman, particularly if it is the patient’s first examination or if it takes place on an emergency basis.

Video case report. Minimally invasive and robotic gynecologic surgery unit of a university hospital. A 31-year-old nulliparous patient with dysmenorrhea, dysuria, dyspareunia, and primary infertility. Bimanual examination, transvaginal ultrasound, and magnetic resonance imaging (MRI) were performed as a comprehensive preoperative workup. The findings were consistent with bladder endometriosis and a 4-cm right pararectal cystic mass suggestive of adenomyosis externa. Laparoscopic excision of all visible endometriosis was performed. A pararectal lesion was found, completely developing in the retroperitoneal spaces, from the right medial pararectal space to the rectovaginal space, reaching the pelvic floor fascia without infiltration of the levator ani muscle. According to Koninckx classification, this kind of lesion corresponds to type III endometriosis or adenomyosis externa. Nerve-sparing eradication of the nodule was performed. The decision to use these techniques was taken with the intention to treat the patient, and not with the aim of testing the procedures performed. Therefore, as a common clinical practice in our institution and for the above reasons, there was no need for consultation of the institutional review board for approval. Improvement of symptoms and spontaneous conception after surgical removal of all endometriotic implants.

She delivered vaginally and had no complications during pregnancy and labor. Neither recurrence of pain symptoms nor voiding or rectal dysfunctions were reported by the patient. In the management of a case of deep endometriosis, the preoperative assessment should be carefully carried out to give the surgeon the most accurate information about the extent of the disease and the patient's main objectives. Imaging techniques such as ultrasound and MRI play a fundamental role along with the clinical evaluation in also detecting lesions that are not visible at first laparoscopic inspection. In this case of a young woman without any detectable fertility issues except for endometriosis, the laparoscopic excision of endometriosis was feasible, safe, and effective in improving the patient's fertility and pain symptoms. The fertility-enhancing potential of complete eradication of pelvic endometriosis, including removal of deep posterior localizations such those presented in this case, has been hypothesized by various investigators.

A step-by-step explanation of the patient's condition, diagnosis, surgical technique, and postoperative results (Canadian Task Force classification II-3). Splenosis consists of ectopic functioning splenic tissue that can be located anywhere within the abdomen or pelvis. Fragments are often multiple and range in diameter from a few millimeters to a few centimeters. They are reddish-blue and are sessile or pedunculated. Their appearance can mimic that of neoplasms or endometriosis, which are the main differential diagnoses. Trauma and subsequent splenectomy is the cause in most cases. Splenosis is a benign condition usually found incidentally and is usually asymptomatic. The need for therapy is controversial, and treatment is suggested only in symptomatic cases, primarily those related to pelvic or abdominal lesions, as in our patient. The diagnosis of splenosis in a woman complaining of pelvic pain may present diagnostic difficulties. The splenic tissue has the macroscopic appearance of endometriosis, and its position in the pelvis also may suggest this diagnosis. Where excision of splenosis is considered necessary, the approach should be laparoscopic, unless this is considered too risky owing to the proximity of vital structures. A 40-year-old woman was referred to our department for severe dyspareunia and dyschezia. The gynecologic examination revealed a painfull nodularity on the posterior vaginal cul de sac. Further evaluation with 2- and 3-dimensional ultrasound and magnetic resonance imaging revealed several soft tissue nodules in the pouch of Douglas (POD), which were enhanced on contrast administration. She had undergone a splenectomy 15 years earlier after a car accident. A laparoscopic approach to a rectovaginal nodularity was performed. Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her legs in abduction. Pneumoperitoneum was achieved using a Veres needle placed at the umbilicus. Four trocars were placed: a 10-mm trocar at the umbilicus for the 0-degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions. In the pelvis, hypervascular and bluish nodules were visible with extension from the POD into the deep rectovaginal space. The macroscopic appearance was atypical for endometriotic implants. The nodularities were carefully dissected and excised, and histological assessment revealed splenic tissue. At the time of this report, the patient had been asymptomatic for 6 months after surgery. Rectovaginal splenosis may mimic endometriosis. The laparoscopic approach to rectovaginal splenosis avoids an abdominal incision, with its associated pain and possible adhesion formation. It also provides a better view for dissection.

A 28 years-old black nulligravida woman was seen for the first time in april 2000 with a chief complaint of infertility. Her past medical history was unremarkable. She had regular menses but associated with severe dysmenorrhea. She also recalled abdominal and pelvic pain for several years.

On histologic examination all specimens (peritoneal biopsies) were compatible with endometriosis and ruled out malignancy. Treatment with Gn RH analog was performed and full remission was obtained after 6 months. One year later the ascites recurred again spontaneously, leading to a third laparoscopy in an other medical institution. Histologic examination showed endometrial stromal tissue and fibrous proliferation. Later she became pregnant after in vitro fertilization.

A technical video showing a step-by-step approach for the resection of deeply infiltrative endometriosis (Canadian Task Force classification level III). Institutional review board approval was not required for this study. There is considerable involvement of the bowel and bladder with deeply infiltrative endometriosis [1-3]. The need for operative procedures involving multiple organs while performing a complete resection is common. The benefits of minimally invasive surgery for a gynecologic pathology have been documented in numerous studies. Patients had fewer medical and surgical complications postoperatively, better cosmesis, and better quality of life [4-6]. We believe that deeply infiltrative endometriosis does not preclude patients from having a minimally invasive resection procedure. In this video, we describe how the robotic platform was used for a seamless transition between surgical specialties including gynecology, colorectal, and urology to ensure complete resection of endometriosis lesions involving multiple organs. A 47-year-old woman with a 4-year history of severe pelvic pain, dysuria, dyspareunia, dyschezia, and dysmenorrhea failing multiple medical therapies presented to our clinic to discuss surgical options. After thorough counseling, the decision was made to proceed with definitive surgical management. Postoperatively, the patient was admitted for 2 days of postoperative inpatient care. After meeting all immediate postoperative milestones, she was discharged with an indwelling Foley catheter and instructed to follow up in the clinic with all 3 surgical specialties. At the 1-week interval, she was seen by the urology team; her indwelling catheter was removed after a cystoscopy was performed documenting adequate healing. Two weeks postoperatively, the patient was seen by the gynecology and colorectal teams and was noted to be healing adequately from the procedure. Her six-week visit was also unremarkable. She continued to follow up with the gynecology team for her yearly well-woman examinations and has been symptom free for 2 years after the surgery. She takes norethindrone daily to minimize recurrence. Preoperative pelvic magnetic resonance imaging (MRI) showed bladder endometriosis and extensive rectovaginal endometriosis. We describe the multidisciplinary approach used for surgery and the procedures performed by each specialty. The urology team performed a cystoscopy preoperatively to assess for full-thickness erosions and the location of those lesions in that event. The urology team also reviewed the magnetic resonance images with the radiology team, and the endometriosis lesions were suspected to be close to the bladder trigone, keeping in mind that this finding could be overestimated given that the bladder was deflated at the time the imaging was obtained. Accordingly, at the time of surgery, the decision was made to proceed with cystoscopy and the placement of ureteral stents as a prophylactic measure. An intentional cystotomy and resection of the bladder section involved with endometriosis were performed followed by watertight closure. The trigone area of the bladder was not involved, and ureteral reimplantation was not needed in this case. The gynecology team operated second and performed an extensive dissection of the retroperitoneal space with the development of the pararectal and paravesical spaces. They also ligated the uterine artery at its origin followed by dissection of the uterovesical space, effectively reflecting the bladder off of the lower uterine segment. At this point, they proceeded with a total hysterectomy, and the specimen was removed from the pelvis through the vaginal cuff. Preoperatively, the colorectal surgeon ordered a colonoscopy to determine if full-thickness erosions were present and reviewed the magnetic resonance images with the radiology team. Based on the MRI and colonoscopy, all patients are counseled and consented for the possibility of a low anterior resection and loop ileostomy to protect the anastomosis. Based on the understanding that colorectal and gynecologic surgeries have a different approach when dissecting the pararectal space at our institution, a discussion between the 2 teams is initiated at the multidisciplinary session for surgery planning. In the case we present, the colorectal surgeon opted for the removal of the uterus before his dissection was initiated given that he dissects this space presacrally and not retroperitoneally like the gynecology counterpart. He would also benefit from the extra space for dissection with the uterus out of the pelvis. The colorectal part of the case was initiated by mobilization of the rectum and dissecting the obliterated rectovaginal space. The presacral space was then opened followed by mobilization of the rectosigmoid from its attachment. The case was concluded with full transection and reanastomosis of the rectum section involved with endometriosis. The specimen was also removed from the pelvis through the vaginal cuff.

Through a comprehensive evaluation by a developmental-behavioral pediatrician and a child psychologist, including administration of the Bayley Scales of Infant and Toddler Development and the Autism Diagnostic Observation Schedule, she was diagnosed with ASD. Her cognitive skills were reported to be within the average range. Soon after the diagnosis, she began receiving 20 hours of applied behavioral analysis (ABA) per week, as well as music therapy, occupational therapy, and a toddler playgroup through early intervention. Four months after the initial diagnosis, her parents reported that she had started making small improvements in her behavior, used more eye contact, and seemed more socially engaged. Approximately 1 year after the diagnosis, she was receiving 6 hours of ABA per week in addition to starting preschool with an Individualized Education Program.

Case report (Canadian Task Force classification III). Private hospital in Curitiba, Paraná, Brazil. A 33-year-old woman was referred to our service complaining about cyclic dysmenorrhea, dyspareunia, chronic pelvic pain, and cyclic dyschezia. Transvaginal ultrasound with bowel preparation showed a 6-cm endometriotic nodule at the retrocervical area, uterosacral ligaments, posterior vaginal fornix, and anterior rectal wall, infiltrating up to the submucosa, 5 cm far from the anal verge. Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her lower limbs in abduction. Pneumoperitoneum was achieved using a Veres needle placed at the umbilicus. Four trocars were placed: a 10-mm trocar at the umbilicus for the zero-degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions, and all implants in the anterior compartment of the pelvis were resected. The lesions located at the ovarian fossae were completely removed. The ureters were identified bilaterally, and both para-rectal fossae were dissected. The right hypogastric nerve was released from the disease laterally. The lesion was separated from the retrocervical area, and the posterior vaginal fornix was resected (reverse technique), leaving the disease attached to the anterior surface of the rectum. The lesion was shaved off the anterior rectal wall using a harmonic scalpel. A x-shaped stitch was placed at the anterior rectal wall using 2-0 mononylon suture. A 33-mm circular stapler was placed transanally under laparoscopic control, and once it reached the area to be resected, it was opened. A gap was created between the envil and the stapler. The anterior rectal wall was placed inside this gap with the aid of the stitch at the anterior rectal wall. The stapler was fired, and a piece of the anterior rectal wall was resected. The same procedure was performed using a 29-mm circular stapler, which allowed for the complete removal of the lesion. We usually perform the second discoid resection using a 29-mm circular stapler to allow an easy progression of the stapler through the rectum beyond the first stapler line, so not to put too much pressure on it. In our experience, the first discoid resection removes most of the disease, and the second discoid resection is only needed to remove a small amount of residual disease, along with the first staple line. The procedure took 177 min, and the estimated blood loss was 100 mL. The patient started clear liquids 6 hours after the procedure, and was discharged 19 hours after that [1]. Pathological examination of the 2 strips of the anterior rectal wall revealed infiltration of the bowel wall by endometriotic tissue. She had an uneventful postoperative course, and was able to re-start sexual intercourse 50 days after surgery. Between January 2010 and January 2015, 315 women underwent laparoscopic surgery for the treatment of bowel endometriosis in our service. Among them, 16 (5.1%) were operated on by using the double discoid resection technique. Median age of the patients was 34 years, and median body mass index was 25.9 kg/m(2). Median preoperative cancer antigen-125 level was 26.5 U/mL (normal value is &lt;35 U/mL). Median size of the rectosigmoid nodule was 35 mm (range: 30-60), and median distance from the anal verge was 10.5 cm (range: 5-15 cm). Median surgical time was 160 min (range: 54-210 min). Concomitant procedures included hysterectyomy (n = 5), partial cystectomy (n = 3), resection of the posterior vaginal fornix (n = 4), and appendectomy (n = 1). Median estimated intraoperative bleeding was 32.5 mL (range: 30-100), and median time of hospitalization was 19 hours (range: 10-41). Median American Fertility Society score was 46 (10-102). Two minor complications (12.5%) occurred in this initial series: 1 patient required bladder catheterization for urinary retention; and 1 patient developed a urinary tract infection that required oral antibiotic treatment. One major complication (6.2%) was observed; the patient developed fever and abdominal pain on the fourth postoperative day. She was re-operated, and the intraoperative diagnosis was pelviperitonitis. The abdominal cavity was inspected for any dehiscence of the bowel and then washed. She was discharged on the second day after re-operation with oral antibiotic therapy. In our daily practice, we are used to discharging our patients soon in the postoperative setting (19 hours for rectal shaving or discoid resection and 28 hours for segmental bowel resection) [1] because the rate of postoperative fistula seems to be low [2]. Because we still have not seen any fistulas after conservative surgery (rectal shaving, discoid resection, and double discoid resection), we usually prefer to perform this type of surgery compared with segmental bowel resection, when possible. Laparoscopic double discoid resection with circular stapler may be an alternative to segmental bowel resection in selected patients with bowel endometriosis." }, { "id": "pubmed23n0047_19990", "title": "[Role of vaginal echography in the investigation of menorrhagia and metrorrhagia in the reproductive years].", "score": 0.009259259259259259, "content": "Eighty non-menopausal patients who had troubles of menorrhagia or metrorrhagia who were neither pregnant nor had cervical pathology, were investigated first by vaginal ultrasound and then by hysteroscopy.

Vaginal ultrasound manages to achieve information about the endometrium and the uterine cavity almost equal to that obtained by hysteroscopy and furthermore it gives more precise information about the state of the myometrium. Vaginal ultrasound therefore seems to be an excellent first stage examination to investigate menstrual disturbances in reproductive life, and so long as it is carried out under good conditions will limit the indications for hysteroscopy and will be able to indicate when it is necessary to carry out simple exploratory hysteroscopy or operative hysteroscopy." }, { "id": "wiki20220301en017_53103", "title": "Dysmenorrhea", "score": 0.00919179229480737, "content": "Further work-up includes a specific medical history of symptoms and menstrual cycles and a pelvic examination.

In some cases, a laparotomy or minilaparotomy has to be performed for technical reasons. This can be avoided in some cases by transvaginal-laparoscopic low anterior rectum resection. The technique is a 4-step procedure, which can be described as follows: step 1 (vaginal) - rectovaginal examination, preparation of the rectovaginal septum, opening of the pouch of Douglas, mobilization of the endometriotic nodule and the rectum, temporary vaginal closure; step 2 (laparoscopic) - removal of additional endometriotic lesions, adhesiolysis, final mobilization of the rectum, mobilization of the rectosigmoid, endoscopic resection using an endoscopic stapler step 3 (vaginal) - transvaginal resection of the lesion, preparation of the oral anvil, closure of the vagina; and step 4 (laparoscopic) - endoscopic transanal stapler anastomosis and underwater rectoscopy, prophylaxis of adhesions, drainage.

Surgical demonstration of complete excision of different types of peritoneal retraction pockets and a comparison with a laparoscopic retroperitoneal cadaveric dissection of the pelvic innervation. Private hospital in Curitiba, Paraná, Brazil. A pelvic peritoneal pocket is a retraction defect in the surface of the peritoneum of variable size and shapes [1]. The origin of defects in the pelvic peritoneum is still unknown [2]. It has been postulated that it is the result of peritoneal irritation or invasion by endometriosis, with resultant scarring and retraction of the peritoneum [3,4]. It has also been suggested that a retraction pocket may be a cause of endometriosis, where the disease presumably settles in a previously altered peritoneal surface [5]. These defects are shown in many studies to be associated with pelvic pain, dyspareunia, and secondary dysmenorrhea [1-4]. Some studies have shown that the excision of these peritoneal defect improves pain symptoms and quality of life [5]. It is important to recognize peritoneal pockets as a potential manifestation of endometriosis because in some cases, the only evidence of endometriosis may be the presence of these peritoneal defects [6]. In this video, we demonstrate different types of peritoneal pockets and their close relationship with pelvic anatomic structures. Case 1 is a 29-year-old woman, gravida 0, with severe dysmenorrhea and catamenial bowel symptoms (bowel distension and diarrhea/constipation) that were unresponsive to medical treatment. Imaging studies were reported as normal, and a laparoscopy showed a posterior cul-de-sac peritoneal pocket infiltrating the pararectal fossa, with extension to the lateral border of the rectum. Case 2 is a cadaveric dissection of a posterior cul-de-sac peritoneal pocket infiltrating the pararectal fossa, with extension to the pelvic sidewall. After dissection of the obturator fossa, we can observe that the pocket is close to the sacrospinous ligament, pudendal nerve, and some sacral roots. Case 3 is a 31-year-old woman, gravida 1, para 1, with severe dysmenorrhea that was unresponsive to medical treatment and catamenial bowel symptoms (catamenial bowel distention and diarrhea). Imaging studies were reported as normal and a laparoscopy showed left uterosacral peritoneal pocket infiltrating the pararectal fossa in close proximity to the rectal wall. Case 4 is a cadaveric dissection of the ovarian fossa and the obturator fossa showing the proximity between these structures. Case 5 is a 35-year-old woman, gravida 0, with severe dysmenorrhea that was unresponsive to medical treatment, referring difficulty, and pain when walking only during menstruation. A neurologic physical examination revealed weakness in thigh adduction, and the magnetic resonance imaging showed no signs of endometriosis. During laparoscopy, we found a peritoneal pocket infiltrating the ovarian fossa, with involvement in the area between the umbilical ligament and the uterine artery. This type of pocket can easily reach the obturator nerve. Because the obturator nerve and its branches supply the muscle and skin of the medial thigh [7,8], patients may present with thigh adduction weakness or difficulty ambulating [9,10]. Case 6 is a cadaveric dissection of the sacrospinous ligament and the pudendal nerve from a medial approach, between the umbilical artery and the iliac vessels. Case 7 is a 34-year-old woman, gravida 1, para 1, with severe dysmenorrhea and catamenial bowel symptoms as well as deep dyspareunia. The transvaginal ultrasound showed focal adenomyosis and a 2-cm nodule, 9-cm apart from the anal verge, affecting 30% of the bowel circumference. In the laparoscopy, we found a posterior cul-de-sac retraction pocket associated with a large deep endometriosis nodule affecting the vagina and the rectum.

The most common presentation is abdominal pain, dysmenorrhea, and abdominal mass secondary to hematocolpos. We present the first case report on Herlyn-Werner-Wunderlich syndrome from Bangladesh. A 15-year-old Asian girl presented with lower abdominal pain of 3 months' duration. She had had menarche 3 months earlier and had a regular menstrual cycle with cyclical abdominal pain. Abdominal examination found a tender mass on the right iliac fossa. Further evaluation with ultrasound revealed distended endometrial cavity filled with complex fluid and nonvisualization of the right kidney. Pelvic magnetic resonance imaging showed absent right kidney and two separate endometrial stripes surrounded by endometrium and a muscular layer. The right endometrial cavity and cervix were distended with blood. This magnetic resonance imaging finding is consistent with Herlyn-Werner-Wunderlich syndrome with uterine didelphyis, right-sided hematometra resulting from obstructed hemivagina, and ipsilateral agenesis of the right kidney. The vaginal septum was resected for vaginoplasty. She was discharged 5 days after surgery and came for follow-up after 7 days. Vaginal examination revealed a healthy wound with no adhesion of the vaginal wall. She also informed us that she had started regular menstruation without any pain 30 days after the operation.

The organism gets attached to the upper respiratory mucosa after inhalation and the majority remain asymptomatic. However, some people may develop symptoms of atypical pneumonia. Psittacosis usually presents with sudden onset fever with chills and rigor, headache, and myalgia. Here we present a case of a 35 years old female with a history of close contact with parrots who presented to the ER with complaints of high-grade fever and headache for 2 weeks which started 2 days after her parrots died. The disease usually manifests as flu-like symptoms or pneumonia and is included in the differential diagnosis of community-acquired pneumonia. Investigations reveal neutrophilia, raised erythrocyte sedimentation rate, C-reactive protein, and elevated liver enzymes which were consistent with the findings of our patient. Chest X-ray showed ill-defined consolidation in the right middle and lower lobes which were inconclusive. Hence, a CT chest was done which revealed patchy ground glass opacities with surrounding consolidation giving a reverse halo sign.

It causes Q fever in humans and animals worldwide. The animal Q fever is sometimes designated \"coxiellosis\". This infection has many different reservoirs including arthropods, birds and mammals. Domestic animals and pets, are the most frequent source of human infections. Q fever may appear basically in two forms, acute and chronic (persistent). The latter form of Q fever in animals is characteristic by shedding C.b. into the environment during parturition or abortion. Human Q fever results usually from inhalation of contaminated aerosols originating mostly from tissue and body fluids of infected animals. Q fever may appear in humans either in an acute form accompanied mainly by fever (pneumonia, flu-like disease, hepatitis) or in a chronic form (mainly endocarditis). Diagnosis of Q fever is based on isolation of the agent in cell culture, its direct detection, namely by PCR, and serology. Detection of high phase II antibodies titers 1-3 weeks after the onset of symptoms and identification of IgM antibodies are indicative to acute infection. High phase I IgG antibody titers &gt;800 as revealed by microimmunofluorescence offer evidence of chronic C.b. infection. For acute Q fever, a two-weeks-treatment with doxycycline is recommended as the first-line therapy. In the case of Q fever endocarditis a long-term combined antibiotic therapy is necessary to prevent relapses. Application of Q fever vaccines containing or prepared from phase I C.b. corpuscles should be considered at least for professionally exposed groups of the population. Infections caused by C.b. are spread worldwide and may pose serious and often underestimated health problems in human but also in veterinary medicine.

Symptoms of acute Q fever may include: chest pain with breathing, cough, fever, headache, jaundice, muscle pains, and shortness of breath. Symptoms of chronic Q fever may include chills, fatigue, night sweats, prolonged fever, and shortness of breath. Q fever is diagnosed with a blood antibody test. The main treatment for the disease is with antibiotics. For acute Q fever, doxycycline is recommended. For chronic Q fever, a combination of doxycycline and hydroxychloroquine is often used long term.

Her chest X-ray showed infiltrate in the right middle lung field. Computed tomography scans revealed ground-glass opacity and surrounding ring-shaped air-space consolidation, the \"reversed halo sign\". Cefpirom was administered, but her symptoms persisted and the infiltrate migrated to the left upper lobe. As cryptogenic organizing pneumonia was suspected, she was then treated with intravenously pulsed methylprednisolone followed by prednisolone. Despite these therapies, acute respiratory failure occurred and she was therefore transferred to our hospital. On admission, severe hypoxemia and diffuse bilateral infiltrates on chest images suggested acute respiratory distress syndrome. As we obtained information that a parakeet had recently died at her home, minocycline was administered, resulting in prompt improvement of the symptoms, respiratory insufficiency and pulmonary infiltrates. Finally, elevated antibody titers against Chlamydophila psittasi confirmed a diagnosis of Psittacosis. Sequential chest computed tomography scans in this case indicate that absorption of marginal air-space consolidation with extended central ground glass attenuation in concordance with a new infiltrate on another lung field appeared to create wandering infiltrate.

Q fever is an influenza-like, transient febrile infectious disease that is common to humans and animals; it develops after the transmission of the infectious agent from livestock or pet animals, but person-to-person transmission is rare. In Europe and the United States, it is ranked fourth or fifth as an underlying cause of community-acquired pneumonia. Many patients with Q fever have a good prognosis, and their mortality is about 1%-2% when left untreated. However, because some patients may take a long time to be cured or may have a chronic condition with poor prognosis, patients with definitely diagnosed Q fever or those strongly suspected of having Q fever are strongly recommended to receive treatment. The definite diagnosis of Q fever is made based on a significant increase in serum antibody titers, the determination of which often requires considerable time, and therefore patients must be monitored for a certain period. Q-fever Coxiella, an obligate intracellular parasite, is basically not susceptible to beta-lactam antibiotics, which barely permeate into the cells, but the parasite is susceptible to tetracyclines, macrolides, and quinolones, with these agents being sufficiently permeable into the cells. However, there are many cases of spontaneous cure, and it is likely that beta-lactam treatment may have been involved in these cases.

Case #2 was a 34-year-old woman whose treatment for SLE included 200 mg of hydroxychloroquine per day since 2017. She arrived at the clinic with a dry cough, asthenia, and myalgias. Case #3 was a 24-year-old woman who had been using 200 mg of hydroxychloroquine per day since 2010. She presented with asthenia, myalgias, headaches, hypogeusia, and anosmia. Case #4 was a 39-year-old woman taking 200 mg of hydroxychloroquine every day for SLE who presented with dyspnea, chest pain, odynophagia, hypogeusia, anosmia, diarrhea, and fever.

Since the risk factors are similar, the probability of Coxiella burnetii seroposititivity is assumed to be also high in this area. The aim of this study was to investigate Q fever and brucellosis seropositivity in patients with acute fever. A total of 53 patients (37 male, 16 female; age range: 18-65 years, mean age: 47.13 ± 16.40 years) who were admitted to the emergency room and infection diseases outpatient clinics of Gaziosmanpasa University hospital with acute fever between June 2011-June 2012 were included in the study. Symptoms, physical examination findings and laboratory test results of the patients were recorded. In addition, their place of residence, relationship with rural area, and history of contacts with animals were questioned. The presence of C.burnetii phase II lgM and lgG antibodies were investigated by indirect immunofluorescent antibody assay, and Brucella spp. antibodies by Rose Bengal and standard tube agglutination methods in the serum samples of patients. C.burnetii seropositivity was determined in 19 (36%) of the patients, and 2 (4%) of them were diagnosed as acute Q fever with the positivity of both lgG and lgM antibodies. Among the seropositive and seronegative patients, there was no statistically significant differences in terms of age, gender, animal contact, occupation, place of residence and relationship with rural-life (p&gt; 0.05). Acute fever was attributed to pneumonia in 10 patients and of them five were found positive for phase II lgG antibodies. There was no significant difference between C.burnetii seropositive and seronegative patients in terms of the presence of pneumonia (p= 0.30). In two patients diagnosed as acute Q fever no signs of pneumoniae were detected in the chest X-rays; one of these cases was resided in the city and the other in the rural area while both had contact with animals. The most frequently detected symptoms in patients with acute Q fever were malaise, fatigue, chills, cough, sputum, dyspnea, nausea, abdominal pain and diarrhea. Brucella seropositivity was detected in 6 (11%) patients and four of them were diagnosed as acute brucellosis. Four of the Brucella seropositive patients were also found positive for C.burnetii. Sixteen (84%) of C.burnetii seropositive patients were male and 3 (16%) were female. Eleven of them were living in the village and eight in the city, however six out of eight urban patients had a history of relation with rural-life, resulting a total of 17 (89%) rural-contacts. In addition, 79% (15/19) of seropositive cases had the history of animal contact most commonly with cattle and sheep (11/15; 73%). When the laboratory findings were compared, serum ferritin levels were found to be significantly higher in patients with acute Q fever then those seronegative patients (874 ng/ml mean value vs. 150 ng/mL mean value; p= 0.04), however there was no significant difference between the other laboratory parameters (p&gt; 0.05). Our data indicated that Q fever seropositivity was quite high in Tokat region and the reason may be attributed to entwined life between rural and urban areas.

Electrocardiogram was normal, but there were significant pleural effusions on chest x-ray. She was strep positive and had blood pressure up to 150/90, prompting admission for cardiac monitoring and cardiology consultation. Blood pressure decreased down to 125/72 without intervention. She was afebrile with unlabored breathing and normal saturations. She was clear to auscultation bilaterally, with no abdominal distension or hepatosplenomegaly, and edema was not evident on exam. There was mild erythema to the bilateral tonsillar pillars. Initial considerations included viral myocarditis, pericarditis, and atypical nephritic syndrome. Workup revealed elevated antistreptolysin antibodies, low C3 complement, negative antineutrophil cytoplasmic antibodies, and negative flu testing. Renal sonography was unremarkable. Cardiology recommended echocardiography, which confirmed pleural effusions but revealed no cardiac abnormalities. Urinalysis revealed hematuria and mild proteinuria. Diagnosis was found to be post-streptococcal glomerulonephritis complicated by fluid overload and left ventricular strain secondary to hypertensive emergency. Post-streptococcal glomerulonephritis is the most common cause of acute glomerulonephritis in children. The mechanism of disease is a proliferation and inflammation of the renal glomeruli secondary to immunologic injury, with deposition of immune complexes, neutrophils, macrophages, and C3 after complement activation. This leads to hematuria, proteinuria, and fluid overload. Edema is present in 65%-90% of patients, progressing to pulmonary involvement in severe cases. Cardiac dysfunction secondary to fluid overload is a potentially fatal outcome in the acute setting.

She described a 3-month history of bilateral lower extremity rash, intermittent knee pain with swelling, and a 2-year history of subjective fevers.

Her initial investigations included an elevated C-reactive protein (CRP) and rheumatoid factor with a weakly positive anti nuclear antibody (ANA). Kidney biopsy was consistent with an immune complex mesangial proliferative glomerulonephritis. Light microscopy showed diffuse global mesangial hypercellularity. Immunofluorescence was positive for trace mesangial IgG and kappa, 1+ IgM, lambda and C1q, and 2+ C3. Electron microscopy showed mesangial electron dense deposits. These findings were felt to be most in keeping with mesangial proliferative lupus nephritis; however, it was acknowledged that clinical and laboratory findings supporting this diagnosis were lacking.

Only very few randomized studies relating to this topic exist in the literature, including a very small number of patients with no class I evidence. We rretrospectively reviewed a series of 221 patients operated on for a head injury during a 25-month period. Of these, 48 patients underwent a decompressive craniectomy. All data available on patients' Glasgow Coma Scale score, pupil size and reaction, and intracranial pressure were collected and analyzed. The patients' outcome was evaluated by the Glasgow Outcome Scale (GOS) and the results compared with the data available in the Traumatic Coma Data Bank. Furthermore, the results were analyzed in respect of the time of surgical intervention (early or late), age, and the preoperative Glasgow Coma Score. Decompressive craniectomy reduced the midline shift in all patients with monolateral diffuse brain edema and contusions having a median value of 7 mm; in the remaining, it ameliorated the basal cisterns effacement. At a mean follow-up of 14 months, 6 (12.5%) patients died, 7 (15%) were discharged home with a GOS of 5, 18 (40%) showed a favorable outcome after rehabilitation with a GOS of 4 and 5, 6 (12.5%) had a severe disability (GOS 3), 9 (20%) were in a vegetative state (GOS 2), and 2 were lost to follow-up. The younger age, earlier surgery, and higher preoperative Glasgow Coma Scale score were related to better outcome (P &lt; .001, P &lt; .05, and P &lt; .034, respectively). Our results seem to support the idea that decompressive craniectomy coupled with neurointensive care may be an effective way to reduce intractable raised intracranial pressure, and probably to improve patients outcome.

One of the main dangers of increased ICP is that it can cause ischemia by decreasing CPP. Once the ICP approaches the level of the mean systemic pressure, cerebral perfusion falls. The body's response to a fall in CPP is to raise systemic blood pressure and dilate cerebral blood vessels. This results in increased cerebral blood volume, which increases ICP, lowering CPP further and causing a vicious cycle.

Although never formally proven to independently improve outcome in prospective, randomized, placebo-controlled trials, there is such a predominance of indirect support for this modality that most neurotrauma protocols are impossible with-out its inclusion and ethical considerations virtually preclude placebo-controlled trials of its efficacy. In addition to the question of improving outcome, ICP monitoring is also useful in guiding the use of potentially harmful treatment modalities such as hyperventilation, mannitol, and barbiturates, and also provides important prognostic data. ICP monitoring provides information on the likelihood of cerebral herniation and allows calculation of the cerebral perfusion pressure (CPP). Although there is no constant threshold for herniation, the most commonly used treatment threshold is 20 to 25 mm Hg. In addition, ICP trends are indispensable in providing the earliest possible indication of critical intracranial mass effects when combined with other clinical indicators. CPP is the difference between mean arterial pressure and ICP. CPP is an important clinical indicator of cerebral blood flow (CBF). Cerebral autoregulation generally remains at least partially preserved after severe head injury, although the CPP value at which it is activated appears to be shifted upward. Therefore, maintaining adequate CBF appears to require using an elevated minimal CPP threshold when treating the injured brain.

The computed tomographic images and data obtained during care of the patient described in this case report provide evidence that hypercarbia can cause increased intracranial pressure and coma without permanent brain injury. Partial pressure of carbon dioxide evaluation for coma is essential to provide faster diagnosis and therapeutic correction in certain common critical disease states. We present the case of a patient in a coma associated with cerebral edema during a typical asthma exacerbation with hypercapnic respiratory failure. An obese 63-year-old African American woman with asthma presented to our hospital with facial swelling and shortness of breath. Immediately following intubation for hypercapnic respiratory failure, she was noted to have a dilated, unresponsive right pupil. An emergent computed tomographic head scan revealed that she had increased intracranial pressure. A neurosurgeon agreed with the computed tomography interpretation and recommended no surgical intervention. The patient's respiratory acidosis was corrected with ventilatory management over several hours in the intensive care unit. Nine and one-half hours later a follow-up head computed tomographic scan was read as normal without cerebral edema. At 12 hours, the patient's right pupil was 5 mm in diameter and reactive. By 24 hours, her pupils were symmetrically equal and reactive. Her symptoms had improved, and she was extubated. A brain magnetic resonance imaging scan revealed no abnormalities. Alteration of consciousness related to hypercapnia during respiratory failure is not generally thought to be related to cerebral edema. Respiratory acidosis resulting from hypercarbia is known to produce carbon dioxide narcosis and coma, but no current treatment algorithm suggests that rapid hypercapnia correction can be critical to neurologic outcome. To the best of our knowledge, our case is a unique example of the physiological changes that may occur in relation to arterial carbon dioxide concentration in the normal brain in the setting of typical hypercapnic respiratory failure. Correction of respiratory acidosis reversed the neurologic symptoms and physiology causing cerebral edema and coma in our patient. Rare similar cases have been sporadically reported in the medical literature, typically in children. Our case is also unusual in that rapid deterioration and clinical status were directly observed on simultaneous computed tomographic scans. Had this patient been found unresponsive, or had she had brief respiratory or cardiac arrest, the scan could have been interpreted as global anoxic injury leading to a different therapeutic course." } ] } } }

The intake of high protein-caloric content diets can improve some nutritional deficits expressed by loss of body weight and anemia. The mechanism responsible for diarrhea is unknown, but truncal vagotomy has the highest incidence. It is usually episodic, lessens over the first year after operation and rarely remains a severe problem. The decreasing levels of colecistokinin response after meal in gastrectomy and the division of hepatic branch of anterior vagus can cause gallbladder sludge and stone formation. Alkaline reflux explains gastritis and esophagitis after partial gastric resection. Surgical duodenal diversion, like a Roux-en-Y limb, have been successful in its control. The mechanism that leads to the dumping syndrome are loss of gastric reservoir function and rapid emptying of hyperosmolar meals into small intestine. Somatostatin analogues improve the symptoms caused by abnormal release of neurohormonal agents responsible of the behaviour of the gastrointestinal tract after meals. Cancer of gastric remanent may be due to increased bacterial overgrowth and nitrosation formation. The endoscopic follow-up is essential for early diagnosis of the stump cancer.

Chronic hypergastrinemia in turn triggers gastric acid hypersecretion yielding in chronic or recurrent or refractory peptic ulcer disease and/or chronic diarrhea. One half of patients with ZES will have distant metastases in the liver by the time the diagnosis is established and one half of all patients with ZES will experience chronic diarrhea as chief complaint rather than peptic ulcer-related symptoms and signs. Gastrinomas have been reported to either manifest sporadically or to occur in conjunction with the genetic background of the MEN-I syndrome. Diagnosis is based on the patients history which is typically characterized by recurrent episodes of peptic ulcer disease or by severe reflux esophagitis and/or diarrhea or by acid-related symptoms which fail to respond to standard treatment regimens. Upper gastrointestinal tract endoscopy will provide evidence for peptic ulcer disease in anatomical regions located aborally the duodenal bulb within the descending part of the duodenum or even farther distally within the jejunum. Peptic ulcers frequently occur in groups indicating some substantial acid hypersecretion. A gastric pH &gt; 2 is mutually exclusive for ZES. Increased serum gastrin levels confirm the diagnosis biochemically. Gastrin secretion can be determined in the basal state or following stimulation with secretin or calcium. High sensitivity and specificity for the diagnosis of ZES is provided by determining the ratio of basal versus pentagastrin-stimulated gastric acid secretion: The ratio of BAO / MAO &gt; 0.6 is highly specific for gastrinoma. To localize the gastrin-secreting tumor computer-assisted tomography, endoscopic ultrasound, and somatostatin receptor scintigraphy provide useful help but most recently, endoscopic ultrasound with high resolution transducers appear to improve preoperative site localization. If modern imaging techniques fail to elucidate the site of the tumor, intraoperative diaphany may help to detect gastrinomas within the duodenal wall. Definitive treatment will only be achieved by total surgical resection of the gastrin-producing tumor in the pancreas or duodenum including dissection of the regional lymph nodes. Control of symptoms will have to be achieved by administration of highly potent proton pump inhibitors in up to 2-3-fold increased standard doses to inhibit gastric acid hypersecretion. Elevation of gastric pH &gt; 4 will be the therapeutic target to protect the mucosa of the upper gastrointestinal tract. Basal acid output should be reduced to less than 10 mEq H(+) per hour which requires administration of highly potent proton pump inhibitors with a recommended starting dose of 60 mg omeprazole equivalents per day." }, { "id": "pubmed23n0759_11962", "title": "Octreotide improves early dumping syndrome potentially through incretins: a case report.", "score": 0.011927546138072453, "content": "Dumping syndrome, or rapid gastric emptying, is a frequent complication after gastric surgery.

The authors screened all patients with peptic ulcer symptoms serious enough to warrant hospital admission or those associated with diarrhea, nephrolithiasis, hypercalcemia, or pituitary abnormality. In a one-year period (1979-1980) nine (of 14 suspected) new gastrinoma patients were identified using a sensitive and specific gastrin radioimmunoassay in combination with provocative tests including IV secretin, calcium, and food. Conventional upper GI series, CAT scan, arteriography, and endoscopy provided no additional information other than to confirm the presence of ulcer disease. Basal plasma gastrin levels were more than 200 pmol L-1 in only three of the nine (normal fasting plasma gastrin levels are less than 25 pmol L-1). Three patients presented with acute ulcer perforation, and the diagnosis of gastrinoma was suspected because of multiple ulcers and pancreatic masses. In three other patients, previous duodenal ulcer surgery had failed. One patient with dyspepsia, high basal plasma gastrin, negative secretin and calcium infusion studies, and a positive meal test was diagnosed as having G-cell hyperplasia; this was confirmed by biopsy and antral gastrin extraction. Antrectomy alone resulted in cure. In all patients tested, a positive calcium infusion or secretin bolus (greater than 100% rise over basal) strongly suggested the diagnosis of gastrinoma, which was confirmed at surgery. In the acute perforations, initial management with omental patch and cimetidine therapy allowed survival of two patients, while emergency total gastrectomy in the third resulted in death due to esophagojejunal leak. Elective patients were treated with cimetidine initially for at least two weeks before total gastrectomy. In this group there were no operative mortalities, and postoperative morbidity was minimal. This series illustrates three important points: (1) careful screening of an ulcer population using gastrin radioimmunoassay and provocative tests has enabled a high yield of gastrinomas while conventional investigations are of minimal values; (2) a high index of suspicion in appropriate cases is necessary; and (3) total gastrectomy performed under elective circumstances is safe and allows the patients to resume a normal and healthy life without the sequelae of aggressive peptic ulceration or daily drug administration." }, { "id": "pubmed23n0069_6586", "title": "Surgical treatment of peptic ulcer disease.", "score": 0.009523809523809525, "content": "Elective surgery for peptic ulcer disease has diminished significantly over the past 15 years. However, emergency surgery has not shown a decline. Some series have even reported an increase in hospitalizations and operations for hemorrhage. The appropriate surgical procedure for peptic ulcer disease must be tailored to the specific needs of the individual patient. During emergency operations for hemorrhage from duodenal ulcer, we recommend suture ligature of the bleeding vessel and vagotomy-pyloroplasty for high-risk patients, or vagotomy-antrectomy for the lower-risk patient. Bleeding gastric ulcers should be resected, if possible. For massive hemorrhage from stress ulceration requiring surgery, near-total or total gastrectomy should be performed. Perforated duodenal ulcers are best managed by closure and a definitive ulcer operation, such as vagotomy-pyloroplasty. Perforated gastric ulcers are best excised but may be simply closed if conditions do not favor resection. In these situations, biopsy should be performed. We recommend truncal vagotomy-antrectomy for patients presenting with obstruction. Vagotomy (truncal or proximal gastric) with drainage is an acceptable alternative in this situation. For patients with intractable ulcer disease or for those who are noncompliant, proximal gastric vagotomy is the preferred operation. However, other operations may need to be considered, depending on the specific situation. Recurrent ulceration needs appropriate work-up to determine the possible cause. Although patients with ulcer recurrence initially may be placed on medical treatment, about 50% will require reoperation. The most effective procedure for peptic ulcer disease is truncal vagotomy-antrectomy, which has a recurrence rate of less than 1%.

Although it is reported as most common with Billroth II gastrectomy, our experience indicates that reflux is nearly as frequent after Billroth I gastroduodenostomy and is not at all infrequent after pyloroplasty. The precise constituents of duodenal fluid which damage the gastric mucosa remain controversial. The best present evidence is that the bile acids are probably essential, but that one or more other constituents of duodenal content are also necessary. The clinical history differs significantly from chronic afferent loop syndrome in that the quality of pain is different, pain tends to be more continuous and less closely related to food-taking, and bile vomiting does not provide dramatic relief, often containing food due to coexistent interference with gastric emptying. Diagnosis is confirmed by gross endoscopic findings and characteristic histopathologic changes in the endoscopic biopsies. Treatment with an interposed isoperistaltic jejunal segment has been disappointing. Only four of ten patients experienced lasting relief, indicating that the relatively short 10 to 12 cm. of jejunum does not adequately prevent duodenogastric reflux.

The question is raised whether the Roux-en-Y reconstruction should not be used primarily, particularly if both vagotomy and antrectomy are to be performed for peptic ulcer.

However, as described above the effect of octreotide on plasma concentrations of marker peptides is not necessarily related to the effect on symptoms. Nevertheless octreotide is capable of producing symptomatic relief in a large proportion of patients with islet cell tumor syndromes. The data on the effect of octreotide on the symptoms due to VIPoma and due to the carcinoid syndrome (presumably including some who have islet cell tumors) are strong and the drug has been approved for these indications by the Food and Drug Administration. With respect to the other islet cell tumor syndromes, the published data suggest that the utility of octreotide differs in the different syndromes. Insulinomas are usually single, benign, and can and should be removed surgically, resulting in cure. Octreotide therefore has no role to play in such patients, particularly since the response of insulinomas is variable. However in the 10 per cent of insulinomas that are malignant octreotide is certainly effective in at least a portion of cases, although as yet the true response rate and efficacy compared with diazoxide is not clear. Although octreotide is effective at reducing acid output, and thus improving symptoms in patients with Zollinger-Ellison syndrome, because of the effectiveness of histamine H2-receptor antagonists and omeprazole, there is no need for octreotide in this syndrome. For patients with glucagonoma, GHRHoma, Cushing's syndrome, and other rare islet cell tumor syndromes octreotide may well be of benefit and should be considered.

The groups were comparable with regard to age, sex, ulcer localisation, indication for surgery and number of emergency procedures. During postoperative follow-up, seven patients with Roux-en-Y have died, compared with nine patients with Billroth II gastrectomy. In two of the seven patients who died after Roux-en-Y gastrectomy, but in none of the nine who died after Billroth II resection, death was unequivocally related to postoperative ulcer recurrences.

Hemodialysis was performed, and a temporary pacemaker was inserted for severe sinus bradycardia. The serum thyroglobulin was 4680 ng/mL (reference range, &lt;32.7 ng/mL). A TSH receptor antibody test was negative. Glucocorticoid therapy and inorganic iodine (100 mg) were administered and continued until day 11. However, her neurological symptoms deteriorated with floppy quadriplegia and deep coma. She gradually recovered. On day 36, she was discharged without any neurological symptoms or thyrotoxicosis. A 64-year-old woman taking lithium for bipolar disorder developed lithium toxicity in the setting of what seemed likely to be a recent onset of thyrotoxicosis due to silent thyroiditis. Thyrotoxicosis may be a contributing cause of lithium toxicity, particularly if it is abrupt in onset and even with cessation of lithium therapy if renal function is compromised.

As she became hypomanic, lithium carbonate at 600 mg/day was commenced, which was increased to 1200 mg/day due to unfavorable therapeutic response. She began to manifest disorientation and abnormal involuntary movement and was therefore referred to our Department of Psychiatry. Her clinical symptoms at admission included consciousness disturbance with marked bilateral symmetrical slow-wave activity in her EEG and choreoathetosis was observed in her face and upper and lower extremities. Cerebellar symptoms were minimal with only mild ataxic gait and finger-to-nose test did not show dysmetria or intention tremor. Her serum lithium level was 3.52 mEq/L, which was clearly in the toxic range. She demonstrated no metabolic abnormalities including hyperglycemia, and was diagnosed with lithium intoxication and treated with water loading and mannitol for forced diuresis.

The most frequent cause of intoxication was attempted suicide. Using neuropsychiatric parametres, intoxication was moderate in 50% of cases, and mild in 25% and severe or very severe in 25%. Using serum lithium levels, intoxication was very severe in 31.35%, severe in 25%, and slight-moderate in 43.7%. Conservative measures were used as the most frequent treatment (50%), and haemodialfiltration was needed in 37.5%. Mean stay was 4,8 days in acute intoxication, and 11.2 days in chronic. Sequelaes were found in two patients (ataxia). Death was not present. Lithium intoxications can involve severe complications, even death.

Change of lithium pharmacokinetics following bariatric surgery may lead to lithium toxicity, which is particularly concerned. We presented a 39-year-old man with morbid obesity and bipolar affective disorder for 20 years, who was treated with lithium. He developed serious lithium toxicity following sleeve gastrectomy and prolonged neurologic sequelae. He suffered from persistent watery diarrhea, general weakness, and then drowsy consciousness. Lithium level was checked immediately to be 3.42 mEq/L and lithium toxicity was diagnosed. After 3 courses of hemodialysis, his serum lithium level subsequently declined to 0.63 mEq/L, while his consciousness returned normal. Lithium was replaced by lamotrigine. The patient was discharged thirty-five days after admission, while his serum lithium declined to 0.06 mEq/L. Neurologic sequelae were noted by muscle weakness and pain sensation in both feet. The nerve conduction test revealed sensorimotor polyneuropathy with conduction block. He was advised to keep a passive range of motion exercise. Although the consensus guideline remains lacking, our report reviewed cases of relevance in the literature and highlighted the awareness of the potential risk of lithium toxicity following bariatric surgery.

Just before his admittance it showed edemas on lower limbs and eyelids, dysnea, severe hemoptysis, paresthesias and general malaise. The immunologic analysis: Acs. glomerular basal antimembrane: negative, ANCA positive with antimieloperoxidasa specificity. The renal biopsy: focal necrotizing glomerulonephritis with semilunar and negative immunofluorescent. The nasas biopsy: unspecified chronic rhinitis. From the clinic point of view, the patient seemed to have the Wegener granulomatosis apart from the fact that he had hemoptysis which is a rare sign in this cases. However, we could not find any granuloma anatomopatologically, which did not clarify this diagnosis. We diagnosed microscopis Poliarteritis, as a third of the cases presented intrapulmonary haemorrhage. Moreover the renal damage it is identical than in the in Wegener granulomatosis. On the top of that, often we can find p-ANCA, which confirms the diagnosis in 99% of cases. Despite our doubt according to the diagnosis the therapeutical treatment of both illnesses is nowadays identical. This means that we were able to begin a precocious treatment with plasmapheresis, metilprednisolona and ciclofosfamida. After a week treatment there was an evident improvement.

In 75 normal subjects aged from 20 to 78 years, retinal sensitivity in the central 10 degree visual field were examined using automated static quantitative perimetry. For background luminance of 31.5 asb, a significant reciprocal correlation was demonstrated between individual mean sensitivity and age. The influence of age on the decrease in sensitivity was proved to differ according to different test locations. To enhance contrast, an image processing procedure was applied for fluorescein angiographs of age-related pathologies which resulted in better recognition of age-related RPE pathologies were recognized. The senile disciform macular degeneration (SDMD) study group sponsored by the Ministry of Health and Welfare performed an epidemiological survey to estimate the number of patients with SDMD. The epidemiological estimation was 6,000 to 13,000 patients in the entire Japanese population. 133 eyes of uni- or bi-lateral senile macular degeneration without choroidal neovascularization and 156 opposite eyes of patients with unilateral SDMD were followed-up for choroidal neovascularization development. Choroidal neovascularization development was confirmed in 15 eyes, 5.2%. In 13 of the 15 eyes, choroidal neovascularization was proved to develop through serous RPE detachment. Also, serous drusen were shown to be to predisposed to choroidal neovascularization through serous RPE detachment. Therefore, it was concluded that senile macular degeneration should be classified into the atrophic form, predisciform or intermediate form and disciform form. In the author's previous paper, it was reported that the navel-like lesion would be a macular lesion predisposing to a senile macular hole. 49 opposite eye of patients with one eye affected by a macular hole were follow-up for macular hole development. At the initial examination, the navel-like lesion was observed in 5 of the 49 eyes. During the course of observation, navel-like lesions developed in one of the other 27 eyes with other abnormalities and in 4 of the 17 eyes without any abnormality. Finally, macular holes developed in 11 of the 49 eyes; in 10 eyes with a navel-like lesion and one eye with another abnormality.

In all patients, best-corrected visual acuity (BCVA) was tested and fluorescein angiography (FA) and optical coherence tomography (OCT) were performed before and about 45 days after treatment. All patients underwent a complete ophthalmologic examination including OCT at least 6 months after treatment. The first patient was treated with one low fluence (300 mW/cm2 for 83 seconds) PDT (6 months follow-up). The second patient was treated with 3 intravitreal injections of bevacizumab 1.25 mg (33 months follow-up) and the third patient was treated with 2 low fluence PDTs at 4 months and, after 1 year, 3 intravitreal injections of bevacizumab 1.25 mg (37 months follow-up). Before treatment, all patients complained of visual loss and metamorphopsia. The OCT showed in the macular area a focal neurosensory detachment with foveal involvement. The FA showed in the macular area multiple focal areas of hyperfluorescence due to pigment epithelium atrophy and in the second and third patient also a hyperfluorescent pinpoint with minimal leakage. After treatment in all eyes, symptoms did not change, BCVA remained stable, and in OCT the foveal neuroretinal detachment was changeless. In FA, no noticeable variation of the hyperfluorescence areas was appreciated. In the second patient, the hyperfluorescent point remained unvaried, and the same occurred in the third patient after the first PDT, while after the second PDT a new leaking dot disappeared.

One of the three eyes was slightly myopic, while the other two eyes were highly myopic. In all three eyes, the macular hole was found to be located in or near the margin of the inferior posterior staphyloma. In one eye, the extent of retinoschisis was rather broad in the margin of the macular hole, and another eye had a history of treatment for choroidal neovascularization. As surgical treatment, the internal limiting membrane in areas surrounding the macular hole was detached after producing artificial posterior vitreous detachment, and a gas tamponade was performed. It was found during surgery that the extensibility of the retina in the margin of the MH was decreased in the three eyes as compared with a usual macular hole. Although the macular hole was successfully closed in all three cases post surgery, the layer structure of the central retina was poorly repaired in all three cases and choroidal neovascularization remained in one case. In all three cases, corrected visual acuity remained at 0.3-0.5 post surgery. Our findings showed poor improvement of visual acuity in all three cases post surgery, even if closure of the macular hole is achieved, thus suggesting that in cases of macular hole associated with tilted disc syndrome and inferior posterior staphyloma, the presence of macular dysfunction existing prior to the onset of macular hole affects visual prognosis." }, { "id": "pubmed23n0900_10038", "title": "Cystoid macular edema associated with preservative-free latanoprost after uncomplicated cataract surgery: case report and review of the literature.", "score": 0.009345794392523364, "content": "Cystoid macular edema associated with latanoprost administration has been reported in patients after complicated cataract surgery with coexisting risk factors.

Recent OCT studies have shown schisislike spaces in connection with the disc. None of the hypotheses of pathogenesis proposed so far could have been proven. Besides the hypothesis of exudation, the role of the vitreoretinal interface is kept in the background of discussion. We describe a case of macular detachment associated with optic pit that regained full vision after pars plana vitrectomy with laser coagulation and gas tamponade over a follow-up of 26 months. The purpose of our case report is to emphasize the role of the vitreoretinal interface in the pathogenesis of macular detachment associated with optic pits. A 32-year-Caucasian woman developed macular detachment associated with an optic pit on her right eye. The vision deteriorated to 24/60. A standard three-port pars plana vitrectomy was performed. After creating a posterior vitreous detachment, all vitreoretinal adhesions were removed carefully. Peripapillary laser coagulation and gas tamponade with 15% C2F6-air mixture followed. For 26 months after surgery the macula has been flat. The vision is 60/60. Besides the exudative component of macular detachment, the vitreoretinal interface seems to play an underestimated role in the pathogenesis of maculopathy associated with optic pits. Tractional forces could explain the delay of macular detachment in young adulthood and the frequency of treatment failure after laser coagulation and gas tamponade. Pars plana vitrectomy with complete removal of all vitreoretinal adhesions should be a suitable technique in the treatment of macular detachment associated with optic pits." }, { "id": "wiki20220301en067_41615", "title": "Metamorphopsia", "score": 0.00917604966852573, "content": "Age-related macular degeneration Epiretinal membrane and vitreomacular traction Posterior vitreous detachment Macular hole Diagnosis Tests used for diagnosis of Metamorphopsia mostly make use of subjective assessments of how a person views regular patterns.

A substantial percentage of these incidentalomas are hormonally active, with 5% to 20% of the tumors producing glucocorticoids. Autonomous glucocorticoid production without specific signs and symptoms of Cushing's syndrome is termed subclinical Cushing's syndrome. With an estimated prevalence of 79 cases per 100,000 persons, subclinical Cushing's syndrome is much more common than classic Cushing's syndrome. Depending on the amounts of glucocorticoids secreted by the tumor, the clinical spectrum ranges from slightly attenuated diurnal cortisol rhythm to complete atrophy of the contralateral adrenal gland with lasting adrenal insufficiency after unilateral adrenalectomy. Patients with subclinical Cushing's syndrome lack the classical stigmata of hypercortisolism but have a high prevalence of obesity, hypertension, and type 2 diabetes. All patients with incidentally detected adrenal masses scheduled for surgery must undergo testing for subclinical Cushing's syndrome to avoid postoperative adrenal crisis. The best screening test to uncover autonomous cortisol secretion is the short dexamethasone suppression test. Because the adrenal origin of a pathologic cortisol secretion is anticipated, the author prefers a higher dexamethasone dose (3 mg instead of 1 mg) to reduce false-positive results. A suppressed serum cortisol level of less than 3 micrograms/dL (80 nmol/L) after dexamethasone excludes significant cortisol secretion by the tumor. A serum cortisol level greater than 3 micrograms/dL requires further investigation, including confirmation by high-dose dexamethasone (8 mg) suppression testing, a CRH test, and analysis of diurnal rhythm. Determination of urinary free cortisol is less useful because increased values are a late finding usually associated with emerging clinical signs of Cushing's syndrome. Patients with suppressed plasma ACTH in response to CRH generally have adrenal insufficiency after surgery and require adequate perioperative and postoperative substitution therapy. Whether patients with subclinical Cushing's syndrome should undergo adrenalectomy is a matter of debate. The author performs surgery in young patients (&lt; 50 years), in patients with suppressed plasma ACTH, and in patients with a recent history of weight gain, substantial obesity, arterial hypertension, diabetes mellitus, and osteopenia. In completely asymptomatic patients with normal plasma ACTH concentrations and in patients older than 75 years, the author recommends a nonsurgical approach. A large prospective randomized study is necessary to evaluate the benefits of surgery versus conservative treatment in patients with subclinical Cushing's syndrome." }, { "id": "pubmed23n0817_15153", "title": "Screening for Cushing's syndrome: is it worthwhile?", "score": 0.017095234703326447, "content": "Cushing's syndrome (CS) is a rare disease characterized by a collection of signs and symptoms, also common in the general population without elevated cortisol secretion.

In this review article the most popular screening test performed in the studies cited was the 1-mg dexamethasone suppression test. Cushing is not frequent enough to support the use of routine screening in patients with morbid obesity and type 2 DM. Also only 1% of hypertensive patients have secondary hypertension due to CS. However, screening should be considered in young patients with resistant DM and/or hypertension. Among patients with osteoporosis and vertebral fractures up to 5% were diagnosed with subclinical hypercortisolism; most of these had adrenal adenoma.

Cushing's disease is the most frequent cause of endogenous Cushing's syndrome, which is 5 or 6 times more frequent than adrenal Cushing's syndrome, with an incidence of between 1.2 and 2.4 cases per million inhabitants per year. Cushing's disease is 3-8 times higher in women than in men. The frequency of adrenal tumors is 3 times higher in women, while that of Cushing's syndrome due to adrenal tumors is 3-5 times higher.

Bilateral micronodular hyperplasia and macronodular hyperplasia are infrequent entities, representing less than 10% of all cases of ACTH-independent Cushing's syndrome. Both familial and sporadic forms exist: the familial form, or Carney complex, and ACTH-independent bilateral macronodular hyperplasia, in which the size of the adrenal glands is considerably enlarged.

However, significant advances in the diagnosis procedures have been made in the past decade. The diagnostic studies involved in the evaluation of patients with suspected Cushing's syndrome fall into two categories: confirming the presence of true hypercortisolism and establishing the precise aetiology. Diagnosis of Cushing's syndrome: ambulatory screening relies on the overnight 1 mg dexamethasone test. Negative tests are confirmed by measuring cortisol in two 24-hour urine samples. If cortisol excretion is slightly above normal, a 48-hour low-dose dexamethasone suppression test or an intravenous infusion dexamethasone suppression test are required. Diagnosis of the aetiology of Cushing's syndrome: the first step is to establish if the hypercortisolism is ACTH-dependent or not. This step is solved by measuring plasma ACTH and cortisol in the late afternoon. Computed tomography scanning of the adrenal glands is required in ACTH-independent Cushing's syndrome. A unilateral tumour will be demonstrated in most of cases. If bilateral lesions are found, dynamic testing using cortisol releasing factor and/or metyrapone must be performed to confirm the ACTH-independency of the syndrome. In ACTH-dependent Cushing's syndrome, the major difficulty is to distinguish between a pituitary source and an ectopic source of ACTH secretion. Magnetic resonance imaging of the pituitary with gadolinium enhancement must be preferred to computed tomography scanning but its sensitivity is not better than 70-80% and false positives can occur. When no macroscopic pituitary lesion can be detected, bilateral inferior petrosal sinus sampling coupled to CRH injection for ACTH measurement will indicate the source of ACTH secretion. If this test indicates the patient has Cushing's disease, pituitary trans-sphenoidal surgery can be performed. If the test indicates the patient has ectopic ACTH-secretion, a cervico-thoraco-abdominal scanning is necessary to identify the tumour. In the case of occult tumour the hypercortisolism must be controlled by pharmacological agents and the imaging investigations must be repeated at appropriate intervals." }, { "id": "pubmed23n0591_1986", "title": "[Management of hypercortisolism].", "score": 0.01404394825447457, "content": "Cushing's syndrome is a rare but frequently considered disease.

Dexamethasone is a glucocorticoid and simulates the effects of cortisol, including negative feedback on the pituitary gland. When dexamethasone is administered and a blood sample is tested, cortisol levels >50 nmol/l (1.81 μg/dl) would be indicative of Cushing's syndrome because an ectopic source of cortisol or ACTH (such as adrenal adenoma) exists which is not inhibited by the dexamethasone. A novel approach, recently cleared by the US FDA, is sampling cortisol in saliva over 24 hours, which may be equally sensitive, as late-night levels of salivary cortisol are high in cushingoid patients.

Timely diagnosis and appropriate treatment can alter the course of the disease and are therefore mandatory.

In patients with equivocal results, second line tests, such as the dexamethasone-suppressed CRH test and desmopressin stimulation, usually enable the diagnosis to be confirmed. Measurement of plasma ACTH then allows the distinction between ACTH-dependent (e.g., pituitary or extrapituitary neuroendocrine tumors) and ACTH-independent causes (e.g., adrenal tumors). The last step in the diagnostic algorithm is often the most fraught with problems as the distinction between Cushing's disease and ectopic ACTH secretion relies on judicious interpretation of several diagnostic procedures. Positive responses to stimulation with CRH and inhibition by high doses of dexamethasone, if concurrent, enable a pituitary origin to be established whereas conflicting results call for inferior petrosal sinus sampling, the latter to be performed in experienced centres only. Visualisation of the tumor at pituitary imaging is helpful but not required for the diagnosis, as microadenomas often remain undectected by MRI and/or CT scan and, on the other hand, visualisation of a non-secreting incidentaloma may be misleading.

Cushing's disease refers only to hypercortisolism secondary to excess production of ACTH from a corticotroph pituitary adenoma (secondary hypercortisolism/hypercorticism) or due to excess production of hypothalamus CRH (Corticotropin releasing hormone) (tertiary hypercortisolism/hypercorticism). This causes the blood ACTH levels to be elevated along with cortisol from the adrenal gland. The ACTH levels remain high because the tumor is unresponsive to negative feedback from high cortisol levels." }, { "id": "InternalMed_Harrison_26973", "title": "InternalMed_Harrison", "score": 0.011113296616837135, "content": "Differential Diagnosis The evaluation of patients with confirmed Cushing’s should be carried out by an endocrinologist and begins with the differential diagnosis of ACTH-dependent and ACTH-independent cortisol excess (Fig. 406-10).

The subjects were divided into four groups: the colorectal resection was associated with (1) stomach resection (13 patients); (2) liver metastasectomy (14 patients); (3) small bowel resection (10 patients); (4) the resection of other organs (13 patients). In the first two years of the study they were examined once in every three months, in the next two years once in every six months and then yearly. The following tests were carried out: chest X ray, abdominal sonography, irrigography or colonoscopy and CEA. On condition that the colonoscope reached the caecum and the result was negative, the test was repeated only a year later. The patients were operated on between 1985 and 1997. The statistical analysis was made with the help of the Kaplan-Meier method. During this period fifty-six complex resections were performed. Out of fifty-six patients fifty were followed. Compliance 89%. In group 1, where the average age of patients was sixty-two years, one patient died in the forty-first and the other in the fifty-second month after the surgery. Survival rate: 11/13 (83%). The survival rates for the other groups were as follows: group 2 (average age 64) twelve patients died within five years. Survival rate 2/14 (14%). The difference between the survival rates in the first two groups in significant (P = 0.0001). Group 3 (average age 67) seven died and only three survived. Survival rate: 3/10 (30%).

Comparing this rate to that of the group 1, the difference is not significant (P &gt; 0.01). Having analysed the results of the four groups it can be concluded that the patients of group 1 lived the longest (stomach resection) and those of group 2 (liver metastasectomy) died the earliest after the operation. It is surprising that the patients of group 3 lived significantly shorter than the ones of group 1 in spite of the fact that they belong by far the greatest number to stage Dukes B (group 1: 12/13 = 92%; group 3: 7/10 = 70%).

Whenever severe dysplasia is present in an adenoma, the necessary therapy is the local excision of the adenoma together with its pedick. An exact complete histological examination is necessary. Between 1976 and 1980 we saw 201 cases of adenoma of the colon or rectum at the Surgical Clinic, University of Düsseldorf. 27 of these cases showed severe epithelial dysplasia. As described in the literature there was a correlation between the size of the adenoma, the histological picture and the risk of malignancy.

The principal aim of this work was to evaluate the prognostic importance of these parameters. A study was made of 320 patients with colorectal cancer who underwent curative extirpation. They had a median age of 58 years, and there were 199 females (62.2%) and 121 males (37.8%). The patients were divided into three age groups: under 40 years old, between 40 and 60 years old and over 60 years old. The tumors were distributed in three intestinal segments: right colon, left colon and rectum. The neoplasms were classified as small (diameter less than or equal to 35 mm) and large (diameter greater than 35 mm). With regard to their form, they were classified as exophytic, when characterized by luminal growth, and endophytic, when there was intramural growth. The involvement of the intestinal circumference at the site of the neoplasm was considered as partial or total. Of the 320 patients, 22 (6.9%) were aged under 40 years, 159 (49.7%) from 40 to 60 years and 139 (43.4%) presented an age of over 60 years.

Both intent-to-treat and completer analyses showed only a statistically insignificant difference in days to resolution (15.4 days in the allopurinol group completers vs 13.4 days in the placebo group; P = 0.5). The secondary measures revealed that the acute phase of pain rapidly improved in both groups.

The article discusses possible medical errors in acute gouty arthritis and during chronic tophaceous gout in the light of the updated international recommendations of the American College of Rheumatology (ACR) and the European Antirheumatic League (EULAR 2018). As an example of inadequate treatment, the authors describe a case of a patient with chronic tophaceous gout. Errors in the diagnosis and treatment of the patient caused various complications and unjustified surgical intervention - amputation of the right finger and removal of a large tophus in the left forearm. Based on the analysis of mistakes made in the diagnosis and treatment of gout, the authors propose an algorithm for therapeutic tactics in different periods of the disease. So, for the relief of exacerbation in acute gouty arthritis, it is recommended to take the following drugs at starting doses: colchicine at a dose of 1.8 mg/day (1.2 mg immediately followed by 0.6 mg 1 hour later during 7-10 days or until complete relief of the gout attack), non-steroidal anti-inflammatory drugs (nimesulide up to 200 mg/day) or glucocorticosteroids (prednisolone at a dose of 30 mg/day for 3-5 days with subsequent withdrawal). The first-line urate-lowering drugs for chronic tofaceous gout are xanthine oxidase inhibitors - allopurinol and febuxostat. Allopurinol is prescribed no earlier than 2 weeks after the arthritis attack has stopped at a starting dose of no more than 100 mg/day, the dose is gradually increased to the minimum effective. The starting dose of febuxostat is 40 mg/day. Also, together with allopurinol or febuxostat, it is recommended to take uricosuric drugs (probenecid 500 mg/day or benzbromarone 50-200 mg/day). At the same time, the authors draw attention to the inadmissibility of the combination of allopurinol and febuxostat. In case of gout that does not respond to the main methods of therapy, treatment with pegloticase is recommended. When prescribing urate-lowering therapy, dose titration is necessary, to avoid the development of toxic effects." }, { "id": "pubmed23n0740_13678", "title": "Initiation of allopurinol at first medical contact for acute attacks of gout: a randomized clinical trial.", "score": 0.01905453225660103, "content": "Streamlining the initiation of allopurinol could result in a cost benefit for a common medical problem and obviate the perception that no treatment is required once acute attacks have resolved. Our objective was to test the hypothesis that there is no difference in patient daily pain or subsequent attacks with early versus delayed initiation of allopurinol for an acute gout attack. A total of 57 men with crystal-proven gout were randomized to allopurinol 300 mg daily or matching placebo for 10 days. All subjects received indomethacin 50 mg 3 times per day for 10 days, a prophylactic dose of colchicine 0.6 mg 2 times per day for 90 days, and open-label allopurinol starting at day 11. Primary outcome measures were pain on visual analogue scale (VAS) for the primary joint on days 1 to 10 and self-reported flares in any joint through day 30. On the basis of 51 evaluable subjects (allopurinol in 26, placebo in 25), mean daily VAS pain scores did not differ significantly between study groups at any point between days 1 and 10. Initial VAS pain scores for allopurinol and placebo arms were 6.72 versus 6.28 (P=.37), declining to 0.18 versus 0.27 (P=.54) at day 10, with neither group consistently having more daily pain.

The five key points to remember in management of the gouty spectrum are: (1) Establish the diagnosis as clearly as possible or as clearly as seems necessary under the clinical circumstances (i.e. arthrocentesis with crystal analysis to establish diagnosis is not always necessary with reliable patients when septic joint seems highly unlikely). (2) Treat acute attacks with NSAIDs alone or perhaps steroids--or rarely IV colchicine under special circumstances. (3) DO NOT START ALLOPURINOL OR PROBENECID DURING AN ACUTE FLARE OF GOUT--IT MAY MAKE THE EPISODE WORSE. (4) The pattern of disease over time (frequency and severity of attacks) determines whether or not one decides to use an agent such as allopurinol, probenecid, or prophylactic colchicine chronically once a patient is over the acute attack--the mere presence of increased uric acid and a single or rare gouty attack would not usually require any other than the appropriate acute therapy.

In recent years, the use of colchicine has declined because of its frequent adverse reactions, and its reduced efficacy when administered more than 24 hours after onset of an acute attack. Intra-articular corticosteroid therapy (e.g. methylprednisolone acetate) is indicated for the treatment of acute mono or oligoarticular gouty arthritis in aged patients, and in those with co-morbid conditions contraindicating therapy with either NSAIDs or colchicine. Oral corticosteroids (e.g. prednisone), and both parenteral corticotrophin (ACTH) and corticosteroids (e.g. intramuscular triamcinolone acetonide) are valuable, relatively safe alternate treatment modalities in those with polyarticular attacks. For the treatment of hyperuricaemia and chronic gouty arthritis, allopurinol is the preferred urate-lowering drug. Its toxicity in elderly individuals, those with renal impairment, and in cyclosporine-treated transplant patients can be minimised by adjusting the initial dose according to the patient's creatinine clearance. In those experiencing cutaneous reactions to allopurinol, cautious desensitisation to the drug can be achieved using a schedule of gradually increasing doses. The therapeutic usefulness of uricosuric drugs is limited by the presence of renal impairment, occurrence of intolerable side-effects, or concomitant intake of salicylates.

Symptom control and termination of the inflammatory process are important early goals, whereas the urate level should be lowered in the long term to prevent further gout attacks and complications. The non-pharmacological approach is based on individually informing the patient on dietary measures and changes of life style. Besides physical measures, such as cold applications on the affected joint, various medications are available for treatment of an acute gout attack. The choice of drug depends on the individual risk profile. If non-steroidal anti-inflammatory drugs (NSAID) and coxibs are chosen it should be taken into account that the use is restricted in patients with renal insufficiency. Moreover, these drugs may have gastrointestinal side effects and are associated with increased cardiovascular morbidity and mortality. Colchicine has gastrointestinal side effects at high dosages but can also be used for differential diagnostics if there is a quick response to treatment. Steroids are an effective alternative and can be given orally or parenterally in patients with dysphagia. Moreover, steroids can be used in cases of renal insufficiency. After symptoms of the acute attack have subsided, urate lowering therapy should be initiated to prevent further attacks. Low-dose urate lowering therapy can be started during an acute gout attack when acute therapy is initiated. Allopurinol is still the medication of choice but its use is restricted in patients with renal insufficiency. A rare but serious side effect is allopurinol hypersensitivity syndrome. Febuxostat can be an alternative in patients who do not tolerate allopurinol. In February 2016, lesinurad, an URAT-1 and OAT-4 inhibitor, was approved in combination with allopurinol or febuxostat.

To assess the efficacy and safety of allopurinol compared with placebo and other urate-lowering therapies for treating chronic gout. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE on 14 January 2014. We also handsearched the 2011 to 2012 American College of Rheumatology (ACR) and European League against Rheumatism (EULAR) abstracts, trial registers and regulatory agency drug safety databases. All randomised controlled trials (RCTs) or quasi-randomised controlled clinical trials (CCTs) that compared allopurinol with a placebo or an active therapy in adults with chronic gout. We extracted and analysed data using standard methods for Cochrane reviews. The major outcomes of interest were frequency of acute gout attacks, serum urate normalisation, pain, function, tophus regression, study participant withdrawal due to adverse events (AE) and serious adverse events (SAE). We assessed the quality of the body of evidence for these outcomes using the GRADE approach. We included 11 trials (4531 participants) that compared allopurinol (various doses) with placebo (two trials); febuxostat (four trials); benzbromarone (two trials); colchicine (one trial); probenecid (one trial); continuous versus intermittent allopurinol (one trial) and different doses of allopurinol (one trial). Only one trial was at low risk of bias in all domains. We deemed allopurinol versus placebo the main comparison, and allopurinol versus febuxostat and versus benzbromarone as the most clinically relevant active comparisons and restricted reporting to these comparisons here.Moderate-quality evidence from one trial (57 participants) indicated allopurinol 300 mg daily probably does not reduce the rate of gout attacks (2/26 with allopurinol versus 3/25 with placebo; risk ratio (RR) 0.64, 95% confidence interval (CI) 0.12 to 3.52) but increases the proportion of participants achieving a target serum urate over 30 days (25/26 with allopurinol versus 0/25 with placebo, RR 49.11, 95% CI 3.15 to 765.58; number needed to treat for an additional beneficial outcome (NNTB) 1). In two studies (453 participants), there was no significant increase in withdrawals due to AE (6% with allopurinol versus 4% with placebo, RR 1.36, 95% CI 0.61 to 3.08) or SAE (2% with allopurinol versus 1% with placebo, RR 1.93, 95% CI 0.48 to 7.80). One trial reported no difference in pain reduction or tophus regression, but did not report outcome data or measures of variance sufficiently and we could not calculate the differences between groups. Neither trial reported function.Low-quality evidence from three trials (1136 participants) indicated there may be no difference in the incidence of acute gout attacks with allopurinol up to 300 mg daily versus febuxostat 80 mg daily over eight to 24 weeks (21% with allopurinol versus 23% with febuxostat, RR 0.89, 95% CI 0.71 to 1.1); however more participants may achieve target serum urate level (four trials; 2618 participants) with febuxostat 80 mg daily versus allopurinol 300 mg daily (38% with allopurinol versus 70% with febuxostat, RR 0.56, 95% CI 0.48 to 0.65, NNTB with febuxostat 4). Two trials reported no difference in tophus regression between allopurinol and febuxostat over a 28- to 52-week period; but as the trialists did not provide variance, we could not calculate the mean difference between groups. The trials did not report pain reduction or function. Moderate-quality evidence from pooled data from three trials (2555 participants) comparing allopurinol up to 300 mg daily versus febuxostat 80 mg daily indicated no difference in the number of withdrawals due to AE (7% with allopurinol versus 8% with febuxostat, RR 0.89, 95% CI 0.62 to 1.26) or SAE (4% with allopurinol versus 4% with febuxostat, RR 1.13, 95% CI 0.71 to 1.82) over a 24- to 52-week period.Low-quality evidence from one trial (65 participants) indicated there may be no difference in the incidence of acute gout attacks with allopurinol up to 600 mg daily compared with benzbromarone up to 200 mg daily over a four-month period (0/30 with allopurinol versus 1/25 with benzbromarone, RR 0.28, 95% CI 0.01 to 6.58). Based on the pooled results of two trials (102 participants), there was moderate-quality evidence of no probable difference in the proportion of participants achieving a target serum urate level with allopurinol versus benzbromarone (58% with allopurinol versus 74% with benzbromarone, RR 0.79, 95% CI 0.56 to 1.11). Low-quality evidence from two studies indicated there may be no difference in the number of participants who withdrew due to AE with allopurinol versus benzbromarone over a four- to nine-month period (6% with allopurinol versus 7% with benzbromarone, pooled RR 0.80, 95% CI 0.18 to 3.58). There were no SAEs. They did not report tophi regression, pain and function.All other comparisons were supported by small, single studies only, limiting conclusions. Our review found low- to moderate-quality evidence indicating similar effects on withdrawals due to AEs and SAEs and incidence of acute gout attacks when allopurinol (100 to 600 mg daily) was compared with placebo, benzbromarone (100 to 200 mg daily) or febuxostat (80 mg daily). There was moderate-quality evidence of little or no difference in the proportion of participants achieving target serum urate when allopurinol was compared with benzbromarone. However, allopurinol seemed more successful than placebo and may be less successful than febuxostat (80 mg daily) in achieving a target serum urate level (6 mg/dL or less; 0.36 mmol/L or less) based on moderate- to low-quality evidence. Single studies reported no difference in pain reduction when allopurinol (300 mg daily) was compared with placebo over 10 days, and no difference in tophus regression when allopurinol (200 to 300 mg daily) was compared with febuxostat (80 mg daily).

Four of the five patients were treated with urate lowering drugs (ULDs) (allopurinol, n = 3; probenecid, n = 1). One patient was treated with colchicine alone. Attention was given to changes in a hyperechoic, irregular coating of the hyaline cartilage in the examined joints (double contour sign or \"urate icing\"). This coating was considered to represent precipitate of MSU crystals. Index joints included metacarpophalangeal (MCP) joints (n = 2), knee joints (n = 3), and first metatarsophalangeal (MTP) joints (n = 2).

It is important to distinguish between therapy to reduce acute inflammation in acute gout and therapy to manage hyperuricaemia in patients with chronic gouty arthritis. During the acute gouty attack nonpharmacological treatments such as topical ice and rest of the inflamed joint are useful. NSAIDs are the preferred treatment in acute gout. The most important determinant of therapeutic success is not which NSAID is chosen, but rather how soon NSAID therapy is initiated. Other treatments include oral and intravenous colchicine, intra-articular and systemic corticosteroids, and intramuscular corticotropin. Optimal treatment of chronic gout requires long-standing reduction in serum uric acid. The urate-lowering drugs used to treat chronic gout are the uricosuric drugs, the uricostatic drugs, which are xanthine oxidase inhibitors, and the uricolytic drugs. Xanthine oxidase inhibitors such as allopurinol, oxipurinol and febuxastat should be used as first-line treatment in patients with renal calculi, renal insufficiency, concomitant diuretic therapy and ciclosporin (cyclosporine) therapy, and urate overproduction. Uricosuric drugs include probenecid, benzbromarone, micronised fenofibrate and losartan. They are the urate-lowering drugs of choice in allopurinol-allergic patients and underexcretors with normal renal function and no history of urolithiasis. The use of recombinant urate oxidase in patients with chronic gout is limited by the need for parenteral administration, the potential antigenicity and production of anti-urate oxidase antibodies, and declining efficacy.

In patients who achieved the sUA target of 6 mg/dl (360 mumol/l), the incidence of gout flares fell steadily and tophi resolved in many patients. The incidence of adverse events such as dizziness, diarrhoea, headache and nausea with febuxostat was similar to allopurinol. The incidence of cardiovascular side-effects (Antiplatelet Trialists Collaboration events) was numerically higher with febuxostat than with allopurinol, but this was not statistically significant. Co-administration of febuxostat with AZA or 6-mercaptopurine is not recommended. Prophylaxis (colchicine and/or NSAIDs) against acute attacks should be used for at least the first 6 months, since early mobilization flares were observed in the clinical trials.

CT scan demonstrated the absence of left submaxillar gland. Minor's test disclosed the affected area and BTX type A was injected (2.5 U/cm2/17 points). A twenty-one-day control showed a 95% reduction of the affected skin area. Persistent efficacy was observed up to one year follow-up time when he was reinjected. The FS, also known as \"gustatory hyperhidrosis\", was probably first reported by M. Duphenix in 1757. Lucja Frey considered its physiopathology as a disorder of both sympathetic and parasympathetic innervation. In our case the FS was caused by a misdirected regeneration of postganglionic parasympathetic nerve fibers that arrised from the nervus lingualis rami ganglionares of the nervus trigeminus. After nerve injury the colinergic parasympathetic fibers seek out colinergic receptors--sympathetic receptors of the skin--innervating sweat glands and small skin vessels. All previous cases were located at masseter region post-parotidectomy. We have not found any description of FS in the submaxillary region. The self-assessed efficacy of the treatment with a hyperhidrosis disease severity scale revealed a very satisfied patient at 20 months follow-up after being injected twice with BTX type A." }, { "id": "pubmed23n0055_18124", "title": "[Treatment of recurrence of pleomorphic adenomas of the parotid gland].", "score": 0.016504329004329004, "content": "This is a retrospective study of 10 patients who underwent surgery for a first or multiple recurrence of pleomorphic adenoma (P.A.).

We have sought to extend the use of this toxin to Frey's syndrome, a relatively frequent complication of parotidectomy. A total of 86 patients participated in the study: 41 males (47.6%) and 45 females (52.4%) ranging in age from 25 to 77 years (average age 51 years). Of these patients 7 (8.1%) had undergone post-operative radiotherapy. Of the 86 patients studied, 18 referred significant symptoms in terms of abundance and frequency. The syndrome was considered severe if the symptoms were present at each meal and if the patient indicated a significant worsening of his quality of life. Intermittent episodes were indicated by 22 patients. The remaining 46 (43.5%) did not complain of any symptoms. The exact extension of the cervicofacial gustatory sweating was evaluated using the Minor test and the involved region was divided into 1 square centimeters sections. The amount of skin surface involved ranged from 10 to 80 square centimeters. The type A neurotoxin was frozen and was reconstituted with a sterile saline solution at a final concentration of 2.5 UI/0.1 ml. The intracutaneous infiltration was performed without anesthesia, infiltrating 0.1 ml of solution, containing 2.5 UI of toxin into the center of each 1 square centimeters section. Statistical analysis was performed to evaluate the potential relationship between how long the treatment was effective, incidence of recurrence, seriousness of the crises and the following variables: age, sex, histology, cutaneous surface involved, injected dose of botulin toxin and post-operative radiotherapy. In the group of 18 patients with severe symptoms (20.9%) the benefit was immediate in all cases although the recurrence rate was 50%. The Frey's syndrome symptoms disappeared within 7 days of infiltration. In the group of 22 patients with less severe involvement (25.5%), the treatment gave positive, definitive results in 16 patients (72.7%).

The treatment decreased the involved area from 20 to 5 cm(2) and the VAS ratings from 98 to 8 mm. The index showed that treatment affected the sweating intensity, not the frequency.

By definition, UTIs in males or pregnant females and those associated with risk factors known to increase the risk of infection or treatment failure (e.g. acquisition in a hospital setting, presence of an indwelling urinary catheter, urinary tract instrumentation/interventions, diabetes mellitus or immunosuppression) are not considered herein. The majority of uUTIs are caused by Escherichia coli (70-95%), with Proteus mirabilis, Klebsiella spp. and Staphylococcus saprophyticus accounting for 1-2%, 1-2% and 5-10% of infections, respectively.

Laboratory testing (i.e. urinary nitrites, leukocyte esterase, culture) is not necessary in this circumstance and empirical treatment can be initiated. The ever-increasing incidence of antimicrobial resistance of the common uropathogens in uUTI has been and is a continuing focus of intensive study. Resistance to cotrimoxazole (trimethoprim/sulfamethoxazole) has made the empirical use of this drug problematic in many geographical areas. If local uropathogen resistance rates to cotrimoxazole exceed 10-25%, empirical cotrimoxazole therapy should not be utilized (fluoroquinolones become the new first-line agents). In a few countries, uropathogen resistance rates to the fluoroquinolones now exceed 10-25%, rendering empirical use of fluoroquinolones problematic. With the exception of fosfomycin (a second-line therapy), single-dose therapy is not recommended because of suboptimal cure rates and high relapse rates. Cotrimoxazole and the fluoroquinolones can be administered in 3-day regimens. Nitrofurantoin, a second-line therapy, should be given for 7 days. beta-Lactams are not recommended because of suboptimal clinical and bacteriological results compared with those of non-beta-lactams. If a beta-lactam is chosen, it should be given for 7 days. Management of uUTIs can frequently be triaged to non-physician healthcare personnel without adverse clinical consequences, resulting in substantial cost savings. It can be anticipated that the optimal approach to the management of uUTIs will change substantially in the future as a consequence of antimicrobial resistance." }, { "id": "pubmed23n0759_24868", "title": "Symptomatic Shigella sonnei urinary tract infection in pregnancy.", "score": 0.014674719220173766, "content": "This report describes a case of urinary tract infection (UTI) due to Shigella sonnei during pregnancy.

Patients who had taken antibiotics in the past 72 hours, had indwelling Foley catheters, symptomatic vaginal discharge, diabetes mellitus, immunodeficiency disorders, or were unable to provide a reliable history were excluded. The patient's clean-catch or catheterized urine specimen was tested immediately by a nurse using a Multistix 9 SG reagent strip. A second aliquot was sent within 1 hour of collection to the hospital laboratory, where a semiautomated microscopic urinalysis and a urine culture were performed. A positive urine culture was defined as more than 100,000 colonies of 1 or 2 uropathogenic bacteria per mL of urine at 48 hours. Dipstick and urinalysis data were compared with urine culture results. Sensitivity, specificity, and predictive values were calculated at various definitions of a positive test, or \"test cutoff points,\" for combinations of leukocyte esterase, nitrite, and blood on dipstick and for RBCs and WBCs on urinalyses. The probability of an erroneous decision to withhold treatment on the basis of a negative test result was defined as \"undertreatment,\" or 1 minus the negative predictive value. \"Overtreatment\" was defined as 1 minus the positive predictive value. Three hundred forty-three patients were enrolled in this study. Twelve patients were withdrawn because of missing laboratory results. Forty-six percent (152/331) of patients had positive urine cultures. If urine dipstick results are defined as positive when leukocyte esterase or nitrite is positive or blood is more than trace, the overtreatment rate is 47% (156/331) and the undertreatment rate is 13% (43/331). If urinalysis results are defined as positive when WBCs are more than 3 per high-power field or RBCs are more than 5 per high-power field, the overtreatment rate is 44% (146/331) and the undertreatment rate is 11% (36/331). Matched pairs of test characteristics were identified when the analysis was repeated using more than 10,000 colonies per mL as a positive culture. In this patient population, similar overtreatment and undertreatment rates were identified for various test cutoff points for urine dipstick tests and urinalysis.

Although the caveat is given in both sets of recommendations that this is particularly appropriate when patients are \"symptomatic,\" referring to urinary frequency with increased thirst and appetite, weight loss, and ketosis, the clinical definition of such presentations may be ill-defined, and it is noteworthy that both documents consider insulin to offer particular benefit under such circumstances. However, with multiple options for glycemic treatment, it is of interest to reconsider this argument for insulin use. It should be recalled that in the UK Prospective Diabetes Study, diet alone was associated with a reduction in HbA1c from 9% to 7%. Drug-naïve people with T2D do often show surprisingly strong reductions in HbA1c with metformin-based dual-agent oral treatment approaches; a recent report showed that even with baseline HbA1c &gt;11%, the combination of metformin with a sulfonylurea, pioglitazone, or sitagliptin was associated with reduction in HbA1c from 11.6% to 6.0%. A 32-week study of the combination of rosiglitazone with metformin in patients with mean baseline HbA1c 8.9% showed a mean HbA1c reduction of 2.3%, and an open-label cohort with baseline HbA1c 11.8% had a reduction in HbA1c to 7.8%. With metformin plus sitagliptin, a mean placebo-adjusted HbA1c reduction of 2.1% from a baseline of 8.8% was reported, with those patients with baseline HbA1c &gt;9% having a 2.6% reduction in HbA1c, and an open-label cohort with baseline HbA1c 11.2% having a 2.9% reduction in HbA1c. Similar 2% HbA1c reductions from baseline levels of 9.1% were seen with metformin in initial combination with the sodium-glucose cotransporter 2 (SGLT2) inhibitor dapagliflozin. Although such dual oral agent approaches are more effective than monotherapy, with a combination regimen the HbA1c reduction will not be directly additive, because the expected reduction decreases at lower baseline HbA1c levels. As an example of this, administration of canagliflozin 300 mg daily to patients with baseline HbA1c &gt;9% reduced levels from 9.6% by 1.8%, whereas at a baseline HbA1c of 10% either canagliflozin 300 mg or metformin 2 g/day reduced HbA1c by 2%; the addition of both agents led to an HbA1c reduction by somewhat less than 3%, which appears concordant with a reduction by the second agent from approximately 8% (10% to 2%). Similar less-than-additive effects of the addition of exenatide QW to dapagliflozin have been reported, with HbA1c reduction from a baseline of 10.0%-10.1% of 1.9% and 1.6% with the individual agents, respectively, and a reduction of 2.2% with their combination. However, one may consider these approaches inferior to the expected HbA1c reduction with insulin, suggesting that insulin should, indeed, be the preferred treatment for people with T2D and HbA1c &gt;9%. Rather, studies comparing basal insulin directly with glucagon-like peptide-1 (GLP-1) receptor agonists (RA) suggest that the latter agents may offer superior benefit. The Diabetes Therapy Utilization: Researching Changes in HBA1C, Weight, and Other Factors Through Intervention with Exenatide Once Weekly (DURATION)-3 and Liraglutide Effect and Action in Diabetes (LEAD)-5 studies compared exenatide QW and liraglutide, respectively, with insulin glargine. Those study participants in the highest quartile of baseline HbA1c had levels ≥9.0% and ≥8.9%, with the GLP-1RA leading to 0.3% and 0.2% greater reductions in HbA1c, respectively, than insulin glargine. Another study comparing T2D patients receiving oral agents given liraglutide with those given insulin glargine showed that those in the highest baseline HbA1c quartile (mean 10.6%) had an HbA1c reduction of 3.1% with either agent. In the exenatide QW study, the reduction in HbA1c with this agent exceeded that with insulin glargine for those groups of study participants with HbA1c 9.0%-9.4%, 9.5%-9.9%, 10.0%-10.4%, 10.5%-10.9%, and even ≥11.0%. Similar superiority of the HbA1c-lowering effect of exenatide QW compared with that of insulin glargine was reported in a study with baseline HbA1c 8.5%. An individual-patient meta-analysis of six studies of another weekly GLP-1RA, namely dulaglutide, showed that at a baseline HbA1c of 10% the expected HbA1c reduction would be nearly 2.5%, and a study directly comparing dulaglutide with insulin glargine also showed a superior HbA1c-lowering effect of the former. Another advantage of the GLP-1RAs is their association with weight loss, rather than the weight gain associated with insulin treatment. An interesting potential combination is that of a GLP-1RA with a thiazolidinedione. In a study comparing the addition of exenatide QW and pioglitazone with the addition of basal-bolus insulin in 101 people receiving sulfonylureas and metformin with baseline HbA1c &gt;10%, HbA1c fell from &gt;11% by &gt;4% compared with &lt;4%, respectively, and the GLP-1RA plus thiazolidinedione treatment was associated with less weight gain and hypoglycemia. What can we conclude? Should HbA1c 11% be the new \"use insulin\" point? Insulin is an important part of our armamentarium for T2D, and is certainly needed for many patients, but with current therapeutic approaches including metformin, incretin-based treatments, SGLT2 inhibitors, and, possibly, thiazolidinediones, we can reconsider its use in many instances. Although there is no doubt that insulin is necessary for truly uncontrolled diabetes, we may wish to better define its correct indications." }, { "id": "pubmed23n0997_15301", "title": "Efficacy of SGLT2 Inhibitors as the Fifth Drug in the Management of Type 2 Diabetes Mellitus in Asian Indians not Controlled with at least 4 Oral Antidiabetic Drugs.", "score": 0.014568764568764568, "content": "To evaluate the efficacy of SGLT2 inhibitors as an add-on therapy along with stricter lifestyle modification in Asian Indian type 2 diabetes mellitus (T2DM) patients with inadequate glycemic control despite receiving an optimum dose of at least 4 oral antidiabetic drugs (OADs).

The aims of this study were to assess the effects of replacing a biguanide with a TZD on glycemic control in patients with poorly controlled type 2 diabetes mellitus, and also to identify the factors affecting interpatient variation in the effects of treatment change. This was a 12-week, open-label, prospective study in which previously prescribed metformin (500 or 750 mg/d) was replaced with pioglitazone (15 or 30 mg/d) in patients with poorly controlled type 2 diabetes mellitus.

This review analyses and critically appraises the literature regarding the optimal therapeutic strategies for T2DM in women after menopause. Lifestyle interventions, including changes in dietary habits and physical exercise in everyday life targeting a modest weight loss (5%), represent the cornerstone of management. Limited intake of alcohol and sodium, as well as smoking cessation, are additional lifestyle changes for both endothelial and bone health. Regarding medications, postmenopausal women should be initially treated with metformin, concurrently with lifestyle intervention. If glycosylated haemoglobin (HbA<sub1c</sub) remains over the target level (usually ≥7%), dipeptidyl peptidase-4 inhibitors (DPP-4i) or glucagon-like peptide-1 receptor agonists (GLP-1RA) should be preferred. Thiazolidinediones (TZDs) and canagliflozin should be avoided in postmenopausal women with increased fracture risk. Insulin should be used with caution to avoid hypoglycaemia. Bariatric surgery is a well established and effective therapeutic option for both weight loss and glycaemic control in very obese patients with T2DM; however, metabolic benefits should be balanced against nutritional deficiencies that often present after surgery. Proper control of hypertension, with avoidance of hypotension, is of great importance as a measure against falls. Annual tests for retinopathy and neuropathy are crucial for the same reason. Menopausal hormone therapy (MHT) has a beneficial effect on glucose homeostasis, reduces the risk of new-onset T2DM and improves glucose control in women with T2DM. T2DM has been considered a cardiovascular disease equivalent, which meant that postmenopausal women with the disease could not take MHT but current evidence supports an individualised approach to this issue. Therapeutic strategies for women with T2DM after menopause should aim to maximise benefits for metabolic, cardiovascular and bone health with the minimum of adverse effects, bearing in mind that most women will spend more than one-third of their life being of postmenopausal status." }, { "id": "wiki20220301en204_12500", "title": "Liraglutide", "score": 0.012455990611330417, "content": "Liraglutide was approved for medical use in the European Union in 2009, and in the United States in 2010.

Novel compounds are represented by the incretin mimetic drugs like glucagon like peptide-1 (GLP-1), the dipeptidyl peptidase 4 (DPP-4) inhibitors, dual peroxisome proliferator-activated receptors (PPAR) agonists (glitazars) and amylin mimetic drugs. We review the cardiovascular effects of these drugs in an attempt to improve knowledge regarding their potential risks when treating T2DM in cardiac patients. Metformin may lead to lethal lactic acidosis, especially in patients with clinical conditions that predispose to this complication, such as recent myocardial infarction, heart or renal failure. Sulfonylureas exert their effect by closing the ATP-dependent potassium channels. This prevents the opening of these channels during myocardial ischemia, impeding the necessary hyperpolarization that protects the cell. The combined sulfonylurea/metformin therapy reveals additive effects on mortality in patients with coronary artery disease (CAD). Meglitinides effects are similar to those of sulfonylureas, due to their almost analogous mechanism of action. Glitazones lower leptin levels, leading to weight gain and are unsafe in NYHA class III or IV. The long-term effects of alpha-glucosidase inhibitors on morbidity and mortality rates is yet unknown. The incretin GLP-1 is associated with reductions in body weight and appears to present positive inotropic effects. DPP-4 inhibitors influences on the cardiovascular system seem to be neutral and patients do not gain weight. The future of glitazars is presently uncertain following concerns about their safety. The amylin mimetic drug paramlintide, while a satisfactory adjuvant medication in insulin-dependent diabetes, is unlikely to play a major role in the management of T2DM. Summarizing the present information it can be stated that 1. Four out the five classical oral antidiabetic drug groups present proven or potential cardiac hazards; 2. These hazards are not mere 'side effects', but biochemical phenomena which are deeply rooted in the drugs' mechanism of action; 3. Current data indicate that the combined glibenclamide/metformin therapy seems to present special risk and should be avoided in the long-term management of T2DM with proven CAD; 4. Glitazones should be avoided in patients with overt heart failure; 5, The novel incretin mimetic drugs and DPP-4 inhibitors--while usually inadequate as monotherapy--appear to be satisfactory adjuvant drugs due to the lack of known undesirable cardiovascular effects; 6. Customized antihyperglycemic pharmacological approaches should be implemented for the achievement of optimal treatment of T2DM patients with heart disease. In this context, it should be carefully taken into consideration whether the leading clinical status is CAD or heart failure." }, { "id": "wiki20220301en343_31357", "title": "Sitagliptin/metformin", "score": 0.011230509903076275, "content": "Medical uses In the United States, sitagliptin/metformin is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes.

This is a typical case of cervical incompetence (and this patient has conization as a risk factor).

This is a typical case of cervical incompetence (and this patient has conization as a risk factor). This pathology consists of dilatation of the cervix in the absence of contractions, requiring cerclage to prevent miscarriage or immature delivery. The cerclage is ideally performed electively, programmed, and not when the patient arrives at the ER "in extemis" (which are also done, but with a lower success rate... the ideal is to do them cold).
A 32-year-old woman requests preconception counseling. The patient reports that she underwent cervical conization for a high-grade intraepithelial lesion (H-SIL) and subsequently had three miscarriages between 20 and 22 weeks gestation. She has no living children. On all three occasions she came to the emergency department with a feeling of weight in the hypogastrium, where she was found to be 8 cm dilated and with prominent amniotic membranes. She had never felt contractions before, what advice would you give her for the next pregnancy?

This question arose early this year during a discussion with my doula partner, who lived in Great Britain for 20 years, and one of the midwives I work with, who attends only homebirths, which is very rare in France. The mom whose case we were discussing was late going into labor but not postdated according to the official pregnancy term here in France (37-42 WA--\"weeks of amenorrhea\"). The midwife expressed her discomfort with waiting. My doula partner and I felt differently, but we knew we were influenced by American and British midwives' practices. I had been shocked the previous December by the position of the chief of the maternity department in a private hospital (a small unit with no residents, in which nurse-midwives attend \"normal\" births and obstetricians are called in case of complications only). This OB explained to my client and me that if she didn't go into labor naturally, she would be called at 41 + 1 for a vaginal exam to check her cervix and would be induced at 41 + 2. Waiting until 42 weeks requires daily checks, for which he has neither the room nor personnel. He clearly stated that it was a matter of management of time and finances. A month later one of our clients reported the story of her brother and sister-in-law's planned homebirth in London. Their doctors had put a lot of pressure on the mother during her pregnancy with gestational diabetes regarding her length of term. They started to talk about induction. The parents didn't feel comfortable with this, and at that point our client had asked me to refer them to someone who could help them there. We referred them to the National Childbirth Trust and to the sweetest doula we know there. This doula (Liliana Lammers) and her famous doctor partner (Dr. Michel Odent) were a good match. The doctor advised waiting, on the condition that the health of the baby and the amount of fluid be checked daily at the local hospital. The mother had already been waiting several weeks past what was supposed to be her term. Finally, she went naturally into labor at home. The doctor and the doula came and, after some hours of observation, decided it would be wiser for the mother to deliver in the hospital. The doctor and doula were not comfortable with the prolonged prelabor, when, at nearly 44 weeks, the health of the baby and the amount of fluid had not been checked for five days. The mother finally had a vaginal birth without drugs at the hospital. After hearing this story, I suggested it would be interesting to collect the official lengths of term and the different routines in other countries as a learning tool and in order to give us something other than French protocol on which to base our practice. So I sent the question to every midwife for whom I had an e-mail address from the last Midwifery Today conference in Paris. Beyond this motivation was my own curiosity regarding the relationship between the official term in each country and its uses and routines. The most significant (because the most unique) answer, in my opinion, is from The Netherlands, where physiology is a priority." }, { "id": "pubmed23n0536_12712", "title": "[What should you tell a patient with a history of cervical incompetence in the first trimester?].", "score": 0.009900990099009901, "content": "Data is now more than ever available to inform couples at risk of second trimester miscarriage or preterm delivery.

She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

This last cerclage is recommended either for women who have ultrasonographic changes consistent with a short cervix or the presence of funneling after the 16-20 weeks gestation (urgent cerclage) and for women who present the asymptomatic dilation of the uterine cervix of at least 2 cm and/or a prolapse of the amniochorial membranes (emergent cerclage). So far there is still a lack of controlled and randomized trials that can unquestionably demonstrate the advantages of the cervical cerclage in comparison with a ''wait and see'' aptitude. The cerclage can be performed either transvaginally, usually according to the McDonald technique, or transabdominally. This last approach is recommended when a transvaginal cerclage has to be avoided because of technical difficulties depending on the conditions of the cervix or when the pregnant woman has a history of one or more failed transvaginal cerclages.

Many factors explain women's choice of abortion in cases of unplanned pregnancies. Early initiation of contraceptive use and a choice of contraceptive choices appropriate to the woman's life are associated with lower rates of unplanned pregnancies. Reversible long-acting contraceptives should be favored as first-line methods for adolescents because of their effectiveness (grade C). Ultrasound scan before an elective abortion must be encouraged but should not be obligatory (professional consensus). As soon as the embryo appears on the ultrasound scan, the date of pregnancy is estimated by measuring the crown-rump length (CRL) or, from 11 weeks on, by measuring the biparietal diameter (BPD) (grade A). Because reliability of these parameters is ±5 days, the abortion may be done if measurements are respectively less than 90 mm for CRL and less than 30 mm for BPD (professional consensus). A medically induced abortion, performed with a dose of 200 mg mifepristone combined with misoprostol, is effective at any gestational age (Level of Evidence (LE) 1). Before 7 weeks, mifepristone should be followed 24-48 h later by misoprostol, administered orally, buccally, sublingually, or even vaginally followed if needed by a further dose of 400 μg after 3 h, to be renewed if needed after 3 h (LE 1, grade A). After 7 weeks, administration of misoprostol by the vaginal, sublingual, or buccal routes is more effective and better tolerated than by the oral route (LE 1). Cervical preparation is recommended for systematic use in surgical abortions (professional consensus). Misoprostol is a first-line agent for cervical preparation at a dose of 400 μg (grade A). Vacuum aspiration is preferable to curettage (grade B). A uterus perforated during surgical aspiration should not routinely be considered to be scarred (professional consensus). An elective abortion is not associated with a higher risk of subsequent infertility or ectopic pregnancy (LE 2). The medical consultation before an elective abortion generally does not affect the decision to end or continue the pregnancy, and most women are sufficiently certain about their choice at this time. Women appear to find the method used most acceptable and to be most satisfied when they were able to choose the method (grade B). Elective abortions are not associated with an increased rate of psychiatric disorders (LE 2). However, women with psychiatric histories are at a higher risk of psychological disorders after the occurrence of an unplanned pregnancy than women with such a history (LE 2). For surgical abortions, combined hormonal contraceptives - oral or transdermal - should be started on the day of the abortion, while the vaginal ring should be inserted 5 days afterwards (grade B). For medical abortions, the vaginal ring should be inserted in the week after mifepristone administration, while the combined contraceptives should begin the same day as the misoprostol or the day after (grade C). Contraceptive implants should be inserted on the same day as a surgical abortion, and may be inserted the day the mifepristone is administered for medical abortions (grade B and C respectively).

Progression of diabetic retinopathy (DR) is a known association. In proliferative DR, there is an increased risk of vitreous hemorrhage (VH) during spontaneous vaginal delivery (SVD) due to the Valsalva maneuver. A 30-year-old female with poorly controlled type I diabetes and hypothyroidism on treatment was following up with the antenatal services at our hospital. This was her second pregnancy having had a previous miscarriage. Three months into her pregnancy, our Ophthalmology service was consulted to assess her and give our advice regarding the safest mode of delivery for her. Questioning revealed that she was following regularly elsewhere for proliferate DR with previous interventions and history of multiple and repeated VHs. When she was seen in our Ophthalmology clinic, she was anxious about the mode of delivery that was best suited for her with regard to her ocular condition. On examination, her visual acuity (VA) without correction was 20/40 in both eyes, improving to 20/20 in the right eye and 20/30 in the left eye after refraction. Her intra-ocular pressure was normal. A dilated fundus examination (DFE) showed changes of high-risk proliferative DR in both eyes and a VH in the right eye. Subsequent follow-up did not reveal any new complaints or concerns. She required one session of pan-retinal photocoagulation (PRP) in her first-trimester visit. DFE showed improvement in VH when compared to her initial examination. After discussing her condition with her obstetrician, it was decided to offer the patient a cesarean section (C/S) delivery, as her risk of developing VH during SVD was greater than normal. At 38 weeks of gestation, she delivered a healthy boy following an uneventful elective C/S. There were no visual complaints throughout her admission for the procedure or thereafter. During the reproductive age, DR is a leading cause of decreased vision. Pregnancy is an independent risk factor for progression of DR, with the stage of DR prior to conception being another. If not managed well, proliferative DR can result in VH, with the risk also existing in relation to SVD due to recurrent Valsalva maneuvers during labor. Our patient who initially presented with proliferative DR in both eyes and a VH in the right eye received one session of PRP to both eyes in the first trimester and was closely followed up throughout her pregnancy thereafter. When her due date neared, it was decided that the safest and most suitable mode of delivery was an elective C/S due to her increased risk of VH related to Valsalva maneuvers during SVD, especially since this was to be her first delivery." }, { "id": "pubmed23n0891_20224", "title": "[Prevention of preterm birth by uterine cervical cerclage].", "score": 0.009433962264150943, "content": "To review the scientific literature on cervical insufficiency and indications of cervical cerclage cervix. The PubMed database, the Cochrane Library and the recommendations from the French and international obstetrical societies between 1972 and June 2016 have been consulted. Cervical insufficiency is a pathophysiological concept and to date no consensual definition is available: the diagnosis is clinical and discussed retrospectively in case of patients with a history of late miscarriages and/or spontaneous preterm delivery, with asymptomatic dilatation of the cervix (professional consensus). The risk of preterm birth is higher in case of surgical cold-knife conisation as compared to loop electrosurgical excision (LE3) and laser vaporization has a negligible impact (LE3). In patients with a history of late pregnancy loss or preterm birth, investigations for the diagnosis of uterine malformation are recommended (grade C). No investigation is recommended for the diagnosis of a cervical insufficiency (professional consensus). A history-indicated cerclage is not recommended in case of only past history of conisation (grade C), uterine malformation (professional consensus), isolated history of preterm delivery (grade B) or twin pregnancies in primary (grade B) or secondary (grade C) prevention of preterm birth. A history-indicated cerclage is recommended for single pregnancy with a history of at least three late miscarriages or preterm deliveries (grade A). In case of history of one or two late miscarriages or preterm deliveries, there are not sufficient arguments to recommend a history-indicated cerclage (professional consensus). Further studies are needed. The ultrasound-indicated cerclage is not recommended in case of short cervical length during the 2nd trimester of single pregnancy without past history of gynecologic or obstetrical event (grade B). In case of past history of a single pregnancy delivery before 34 weeks gestation (WG), ultrasound cervical length screening is recommended between 16 and 22 WG in order to propose a cerclage in case of length&lt;25mm before 24 WG (grade C). Ultrasound-indicated cerclage is not recommended for multiple pregnancy with a short cervix (grade B). Emergency cerclage using the MacDonald technique is recommended during the second trimester of pregnancy in case of major changes of the cervix, with or without protrusion of the fetal membranes, but without premature rupture of membranes or chorioamnionitis (grade C). Tocolysis and antibiotics during cerclage should be considered individually (professional consensus). There is no reason to recommend a period of expectative before considering an emergency cerclage (professional consensus). A maximum gestational age to perform a cerclage cannot be recommended (professional consensus). A cervico-isthmic cerclage can be discussed in case of failure of MacDonald cerclage (professional consensus). Scientific data are insufficient to recommend or not a vaginal bacteriological analysis before performing a cerclage (professional consensus). The use of double cerclage does not improve perinatal outcome (NP3) and is not recommended (grade C). There is insufficient scientific argument to recommend a type of stitch over another (grade C). The available data are not in favor of a superiority of the Shirodkar cerclage in case of history- or ultrasound-indicated cerclage and the MacDonald cerclage is firstly recommended because technically easier and less risky (grade C). Overall, complications of cerclage are rare but potentially serious. The occurrence of complications is no different between the history-indicated and echo-indicated cerclage (LE4). There is no scientific evidence on the benefit of bed rest and adjuvant treatments (antibiotics or indomethacin) during history or ultrasound-indicated cerclage (professional consensus).

The Pubmed database, the Cochrane Library and the recommendations from the French and foreign Gyn-Obs societies or colleges have been consulted. The number of induced abortions (IA) has been stable for several decades. There are a lot of factors explaining the choice of abortion when there is an unplanned pregnancy (UPP). Early initiation and choice of contraception in connection to the woman's life are associated with lower NSP. Reversible contraceptives of long duration of action should be positioned fist in line for the teenager because of its efficiency (grade C). Ultrasound before induced abortion must be encouraged but should not be obligatory before performing IA (Professional consensus). As soon as the sonographic apparition of the embryo, the estimated date of pregnancy is done by measuring the crown-rump length (CRL) or by measuring the biparietal diameter (BIP) from 11 weeks on (grade B). Reliability of these parameters being±5 days, IA could be done if measurements are respectively less than 90mm for CRL and less than 30mm for BIP (Professional consensus). A medical IA performed with a dose of 200mg mifepristone combined with misoprostol is effective at any gestational age (EL1). Before 7 weeks, mifepristone followed between 24 and 48hours by taking misoprostol orally, buccally sublingually or eventually vaginally at a dose of 400 ug possibly renewed after 3hours (EL1, grade A). Beyond 7 weeks, misoprostol given vaginally, sublingually or buccally are better tolerated with fewer side effects than oral route (EL1). It is recommended to always use a cervical preparation during an instrumental abortion (Professional consensus). Misoprostol is a first-line agent for cervical preparation at a dose of 400 mcg (grade A). Aspiration evacuation is preferable to curettage (grade B). A perforated uterus during an instrumental suction should not be considered as a scarred uterus (Professional consensus). IA is not associated with increased subsequent risk of infertility or ectopic pregnancy (EL2). The pre-abortion medical consultations does not affect, most of the time, the decision to request an IA. Indeed, a majority of women is quite sure of her choice during these consultations. Acceptability of the method of IA and satisfaction appears to be larger when they are able to choose the abortion method (grade B). There is no relationship between an increase in psychiatric disorders and IA (EL2). Women with psychiatric histories are at increased risk of mental disorders after the occurrence of an UPP (EL2). In case of instrumental abortion, oral estrogen-progestogen contraceptives and the patch should be started from the day of the abortion, the vaginal ring inserted within 5 days of IA (grade B). In case of medical abortion, the vaginal ring should be inserted within a week of taking mifepristone, oral estrogen-progestogen contraceptives and the patch should be initiated on the same day or the day after taking prostaglandins (grade C). In case of instrumental abortion, the contraceptive implant may be inserted on the day of the abortion (grade B). In case of medical abortion, the implant can be inserted on the day of mifepristone (grade C). The copper Intrauterine Device (IUD) and levonorgestrel should be inserted preferably on the day of instrumental abortion (grade A). In case of medical abortion, an IUD can be inserted within 10 days following mifepristone after ensuring by ultrasound of the absence of intrauterine pregnancy (grade C).

Dr. Kotha Pannikar, chairman of the Kedah Family Planning Association (FPA) in Malaysia, illustrated this point in discussion which followed the Consultation of Medical and Communication Fieldworkers conference in Kuala Lumpur in August, with a story about 1 of her own patients. When the girl, who had a rheumatic heart, was 16, Dr. Pannikar advised the parents that she needed cardiac surgery if she were to be a healthy wife and mother. But the parents lived some distance from Dr. Pannikar's surgery and did not heed the advice. The girl was married to a carpenter from a traditional Chinese family, in which \"the man is lord and master.\" Her new home had no piped water, and in additional to normal domestic tasks she had to carry water from a source 1 1/2 miles agay. In the 7th month of her 1st pregnancy, she went into cardiac failure. After the 3rd pregnancy and a 3rd cardiac failure, Dr. Pannikar tried to arrange a sterilization \"but we could not get consent - her husband refused to turn up at the hospital.\" When the girl was admitted to hospital 6 months into her 4th pregnancy, Dr. Pannikar got hold of her patient's mother-in-law. \"I told her if she wanted a servant in the house, it was easy to get one. But no servant would look after her grandchildren the way their mother would. I told her if she wanted to save the girl's life she had better speak to her son.\" During the 4th delivery, the girl went into cardiac arrest and spent 2 weeks in intensive care. The mother-in-law prevailed upon her son to at least consent, and the girl was sterilized before she left hospital. But \"it was a very near thing,\" Dr. Pannikar recalls \"and it wouldn't have happened if the husband had felt he was responsible in parenthood.\" The Kedah FPA makes special efforts to reach men. Dr. Pannikar herself talks to men's organizations like the Lions and Rotary Clubs, and arranges education programs for trade unions and workers on the rubber estates. She thinks women need to be told repeatedly that they have a basic human right to choose whether they want to have a baby, and when. \"Women feel,\" she says, \"that their only function is to cook, wash clothes and feed the baby.

Given the limited scientific evidence on the manifestations and potential impact of this virus on pregnancy, we decided to report this case. The patient was a 38 year-old Iranian woman with a triplet pregnancy and a history of primary infertility, as well as hypothyroidism and gestational diabetes. She was hospitalized at 29 weeks and 2 days gestational age due to elevated liver enzymes, and finally, based on a probable diagnosis of gestational cholestasis, she was treated with ursodeoxycholic acid. On the first day of hospitalization, sonography was performed, which showed that biophysical scores and amniotic fluid were normal in all three fetuses, with normal Doppler findings in two fetuses and increased umbilical artery resistance (pulsatility index [PI] &gt; 95%) in one fetus. On day 4 of hospitalization, she developed fever, cough and myalgia, and her COVID-19 test was positive. Despite mild maternal symptoms, exacerbated placental insufficiency occurred in two of the fetuses leading to the rapid development of absent umbilical artery end-diastolic flow. Finally, 6 days later, the patient underwent cesarean section due to rapid exacerbation of placental insufficiency and declining biophysical score in two of the fetuses. Nasopharyngeal swab COVID-19 tests were negative for the first and third babies and positive for the second baby. The first and third babies died 3 and 13 days after birth, respectively, due to collapsed white lung and sepsis. The second baby was discharged in good general condition. The mother was discharged 3 days after cesarean section. She had no fever at the time of discharge and was also in good general condition. This was a complicated triplet pregnancy, in which, after maternal infection with COVID-19, despite mild maternal symptoms, exacerbated placental insufficiency occurred in two of the fetuses, and the third fetus had a positive COVID-19 test after birth. Therefore, in cases of pregnancy with COVID-19 infection, in addition to managing the mother, it seems that physicians would be wise to also give special attention to the possibility of acute placental insufficiency and subsequent fetal hypoxia, and also the probability of vertical transmission." }, { "id": "pubmed23n0751_888", "title": "Prolonged and post-term pregnancies: guidelines for clinical practice from the French College of Gynecologists and Obstetricians (CNGOF).", "score": 0.008771929824561403, "content": "The duration of pregnancy varies between 40(+0) and 41(+3) weeks. Conventionally, and essentially arbitrarily, a pregnancy is considered to be \"prolonged\" after 41(+0) weeks, but the infant is not considered \"post-term\" until 42(+0) weeks (Professional consensus). A term birth thus occurs during the period from 37(+0) to 41(+6) weeks. In France, prolonged pregnancies (≥41(+0)weeks) involve 15-20% of pregnant women, and post-term pregnancies (≥42(+0) weeks) approximately 1%. The frequency of post-term pregnancies is very heterogeneous: in Europe and the United States, it ranges from 0.5% to 10% according to country. In prolonged pregnancies, the cesarean section rate-especially the emergency cesarean rate-is multiplied by approximately 1.5 (grade B). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly, from 0.7‰ to 5.8‰. Meconium aspiration syndrome is responsible for substantial morbidity and mortality, and its incidence increases regularly between 38(+0) and 42(+6) weeks, from 0.24‰ to 1.42‰ (grade B). Similarly, the risks of neonatal acidosis (grade B), 5-min Apgar scores less than 7 (grade B) and admissions to neonatal intensive care (grade B) increase progressively between 38(+0) and 42(+6) weeks. These risks appear to double for post-term growth-restricted newborns (grade C). Ultrasound dating of the pregnancy makes it possible to reduce the risk that it will be incorrectly considered prolonged and that labor will therefore be induced unnecessarily. To harmonize practices, if the crown-rump length (CRL) is correctly measured (this measurement should be taken between 11(+0) and 13(+6) weeks, when CRL should measure from 45 to 84mm), ultrasound dating based on it should be used to determine the official date pregnancy began, regardless of its difference from the date assumed by the patient or estimated based on the date of the last menstrual period. This rule does not apply to pregnancies by IVF, for which the date pregnancy began is defined by the date of oocyte retrieval (Professional consensus). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly and there is no threshold at which a clear increase in perinatal mortality becomes visible. Fetal monitoring by cardiotocography (CTG) that begins at 41(+0) weeks would cover approximately 20% of women and reduce perinatal morbidity compared with monitoring that begins at 42(+0) weeks (grade C). The frequency recommended for this monitoring ranges between two and three times a week (Professional consensus). For ultrasonography assessment, measurement of the largest fluid pocket is recommended, because measurement of the amniotic fluid index (that is, the sum of the four quadrants) is accompanied by more diagnoses of oligohydramnios, inductions of labor, and cesareans for fetal distress without any improvement in neonatal prognosis (grade A). The practice of assessing the Manning biophysical score increases the number of diagnoses of oligohydramnios and fetal heart rage (FHR) abnormalities and generates an increase in the rates of inductions and cesareans without improving neonatal prognosis. The use of this biophysical score in monitoring prolonged pregnancies is therefore not recommended (grade B). In the absence of a specific disorder, induction of labor can be proposed in patients between 41(+0) and 42(+6) weeks (grade B). Nonetheless, the choice of prolongation beyond above 42(+0) weeks appears to involve an increase in fetal risk, which must be explained to the patient and balanced against the potential disadvantages of induction (Professional consensus). Stripping the membranes can reduce the duration of pregnancy by increasing the number of patients going into labor spontaneously during the week afterward (grade B). Compared to an expectant approach, it does not increase the cesarean section rate (grade A). It reduces recourse to induction by 41% at 41(+0) weeks and by 72% at 42(+0) weeks (grade B), without increasing the risk of either membrane rupture or maternal or neonatal infection (grade B). Used as a tampon or vaginal gel, prostaglandins E2 (PGE2) are an effective method of inducing labor (grade A). They can be used to induce labor successfully, regardless of cervical ripeness (grade A). If misoprostol is chosen, the lowest dose is to be preferred, starting with a vaginal dose of 25μg every 3-6h (grade A). For misoprostol, more powerful studies remain necessary for better defining the doses, routes of administration, tolerance and indications. Misoprostol at any dose is contraindicated in women with uterine scars (grade B). Placement of an intracervical Foley catheter is an effective mechanical means of inducing labor, with less uterine hyperstimulation than prostaglandins and no increase in the cesarean section rate (grade A). Nonetheless, as the risk of infection might be increased, this technique requires more robust evaluation before entering general practice (grade B). In cases of meconium-stained amniotic fluid, pharyngeal aspiration before delivery of the shoulders is not recommended (grade A). The team managing a post-term newborn with meconium-stained amniotic fluid at birth must know how to perform intubation and, if the intubation is not helpful, endotracheal aspiration (grade C) and ventilation with a mask. Routine endotracheal intubation of a vigorous newborn is not recommended (grade A)." }, { "id": "Obstentrics_Williams_5759", "title": "Obstentrics_Williams", "score": 0.008695652173913044, "content": "pregnancy continuation.

In the case we present here, a patient is diagnosed with a delayed mechanical complication after AMI, and a swift management plan is made with the aid of point-of-care BECH. The patient is a 72-year-old man with dyspnea who was admitted to the ED 5 days after receiving a primary percutaneous coronary intervention with stent implantation for AMI; in the ED, the patient was diagnosed, via BECH, with a VS rupture.

A cardiac examination revealed a new 2/6 harsh holosystolic murmur along the left sternal border without pretibial oedema. Emergency physicians performed BECH, and subcostal views of the heart revealed a wide interventricular septal rupture and left-to-right shunting with minimal pericardial effusion. The patient underwent surgery immediately to repair the defect. The post-operative course was uneventful, and he was discharged in stable condition on the seventh day after the surgery.

Transmural infarction was observed in 9 cases: the infarct was electrocardiographically non-transmural in 1 case. Emergency echocardiography showed pericardial effusion in all cases, usually moderate, but sometimes compressive with an intrapericardial echogenic mass suggesting a thrombus. Haemodynamic improvement was obtained by medication allowing cardiac catheterisation which showed adiastole in 3 cases. Coronary angiography was performed in 7 cases. In 5 of the 7 cases, apart from occlusion of the artery presumed to be responsible for the infarct, the coronary vessels were diffusely infiltrated without significant stenosis.

Patients normally present with hemodynamic instability, often in cardiogenic shock. Despite improvements in surgical techniques and diagnostic tools, post-myocardial infarction ventricular rupture remains a difficult therapeutic challenge. There are three categories of ventricular rupture: free wall rupture (FWR), ventricular septal rupture (VSR), and papillary muscle rupture (PWR). The incidence of FWR occurs following up to 10% of myocardial infarctions. VSR and PWR have a lower incidence of 1-2% and 0.5-5%, respectively. Patients often present with single-vessel coronary artery disease and usually do not have a positive history for a previous myocardial infarction. The incidence of post infarction angina in these patients is significantly greater than in patients without ventricular rupture. Delay in treatment and continued physical activity post infarction increases the risk of ventricular rupture. Diagnostic tools such as two-dimensional echocardiography and cardiac catheterization confirm the diagnosis of ventricular rupture in only 45-88% of cases. Knowledge of the disease progression is necessary to insure accurate and timely diagnosis. Due to the rapid deterioration of these patients, there is a 50-80% mortality rate within the first week if untreated. With surgical correction, patients can extend their 5-year survival rates to 65%. A good example of the complex course of ventricular rupture is the case of a 71-year-old patient at our institution.

Consequently we have investigated the short- and long-term results of isolated myocardial revascularization in patients who are in their ninth decade of life. Between 1 January 1995 and 31 December 1998, 121 patients (51 women, 70 men, age 80 to 88 years, median: 82 years) underwent isolated coronary artery bypass grafting. As part of the revascularization, a unilateral internal mammary artery graft (IMA) was used in 87% of cases. The in-hospital mortality was 6.6%. Analysis of predictors of mortality unveiled the following factors: ejection fraction less than 50%; history of recent left ventricular failure; extent of coronary artery disease; perioperative use of an intraaortic balloon pump (IABP) and symptomatic pericardial effusion. Use of the IMA revealed no influence on in-hospital mortality. The median follow-up time was 20 months (range: 2-48 months). Survival rates after 1, 2, and 3 years were 93.1%, 87.3% and 73.7% for women and 86.9%, 82.5% and 65.1% for men. These survival rates were comparable with those of the entire 82 year old population. Predictors for late death were male gender, history of stroke, history of arterial embolism, and postoperative pulmonary failure resulting in mechanical ventilation. During the follow-up period myocardial infarcts were subsequently not observed. Freedom from angina after 1, 2 and 3 years was 90.1%, 82.6% and 78.1%, respectively.

Here, we reported an application of this method to dynamically assess regional pulmonary perfusion defect in a patient with acute massive pulmonary embolism. A 68-year-old man experienced sudden dyspnea and cardiac arrest during out-of-bed physical activity on the first day after partial mediastinal tumor resection. Acute pulmonary embolism was suspected due to acute enlargement of right heart and fixed inferior venous cava measured with bedside ultrasound. The computed tomography pulmonary angiography further confirmed large embolism in both left and right main pulmonary arteries and branches. The regional time impedance curves, which were obtained by a bolus of 10 ml 10% NaCl through the central venous catheter, were then analyzed to quantitatively assess regional perfusion. Normal ventilation distribution with massive defects in regional perfusion in both lungs was observed, leading to a ventilation-perfusion mismatch and low oxygenation index (PaO<sub2</sub/FiO2 = 86 mmHg) at the first day of pulmonary embolism. The anticoagulation was performed with heparin, and the patient's condition (such as shock, dyspnea, hypoxemia, etc.), regional lung perfusion defect, and ventilation-perfusion mismatch continuously improved in the following days.

A man, 60 years old, was admitted to a Medical Division of our hospital for the appearance of chest pain and epigastric pain during effort in the last year. He smoked 20 cigarettes a day and drank wine (1 or 2 litres a day). He was affected by hypercholesterolemia and in the past reported relapsed thrombophlebitis in the left leg. Four years before admission to our hospital he underwent large and small left saphenectomy. He had no cardiac events in the past. After a non significant exercise stress test the patient was treated with nitrates and asa and was discharged from the hospital. At home the symptoms increased and after 8 months the patient was admitted again to the Cardiologic Division of the hospital. At admission he reported dyspnea and chest pain at rest, not only during effort and the ECG showed negative T waves in anterior and inferior leads. Intravenous heparine, nitrates and calcium antagonists stabilized the clinical picture. The following examinations revealed: reduction of the T wave negativity at the ECG registered during chest pain; mild enlargement of the heart at the chest roentgenogram; normal value of the left ventricle and apical and midseptal by ipokinesia at the transthoracic echocardiogram; normal coronary artery at the coronary arteriography. \"Vasospastic angina\" was diagnosed and the patient was discharged after 20 days, asymptomatic. After 15 days he returned to the hospital again for chest pain, dyspnea, hypotension and syncope despite therapy. At physical examination he showed a painful left tibio-tarsal tumefaction, an increased and splitting second heart sound in the pulmonary area and a systolic murmur in the third and fourth left interspace. The ECG showed a severe anterior ischemia, while a new transthoracic echocardiogram revealed a considerable dilatation of the right atrium, right ventricle and the main pulmonary artery with severe tricuspid regurgitation and pulmonary hypertension (mean PAP about 50 mmHg). The following pulmonary perfusion scintigraphy confirmed the diagnosis of pulmonary embolism and the selective right and left pulmonary arteriography exhibited multiple thrombi and large intravascular filling defects. The right heart catheterization confirmed a chronic precapillary pulmonary hypertension (mean PAP = 55 mmHg). About 24 hours after these examinations the patient died because of a cardiac arrest with electromechanical dissociation. Pulmonary thromboembolism is a potentially fatal disease characterized by a largely variable clinical presentation. Frequently pulmonary embolism diagnosis is difficult especially when clinical findings are unusual. In the case observed the \"typical\" chest and epigastric pains associated with the electrocardiographic findings directed diagnosis towards myocardial ischemia. Also after the coronary arteriography that showed normal coronary artery, the erroneous diagnosis persisted. Pulmonary embolism was correctly diagnosed too late to begin an effective therapy.

All patients were treated with heparin, administered with therapeutic prolongation of aPTT. Clinically acute PE (if possible confirmed with angiography, TC and/or echocardiography) was treated with rtPA administered in 10 minutes lasting bolus in doses 0.6-0.8 mg per kg of body weight (50 mg of rtPA during 10 minutes administered into peripheral veins). In 9 patients with pulmonary hypertension, significant decrease of tricuspidal gradient (measured echocardiographically during several hours after administration of rtPA) was documented. Improvement in PaO2, SaO2 and decrease of heart rate and respiratory rate were also achieved. No serious bleeding complications were observed after mentioned treatment. Control investigations (conventional contrast-enhanced CT and spiral CT) performed several days after rtPA administration revealed thrombus in pulmonary artery.

A 79-year-old man presented with severe osteoarthritis of bilateral knees, with adaptation of total knee arthroplasty (TKA). Transthoracic echocardiogram revealed severe pulmonary hypertension with estimated right ventricular systolic pressure of 140 mm Hg. Pulmonary arteriography revealed total occlusion of the upper branch of the right pulmonary artery, and ventilation/perfusion scan showed multiple mismatched perfusion defects. His pulmonary artery pressure (PAP) was as high as 89/25 (46) mm Hg with normal range of pulmonary capillary wedge pressure. He was diagnosed with CTEPH. Four BPA sessions for 8 branches of the bilateral pulmonary arteries were done, until the mean PAP (mPAP) went under 30 mm Hg.

Appropriate therapy can dramatically reduce the incidence of both. Oxygen and heparin therapy should be started as soon as the diagnosis is suspected. The condition of a hypotensive patient with right ventricular overload from acute pulmonary embolism usually is made worse by a fluid challenge; hypotension may be relieved by preload reduction or even by gentle diuresis. Norepinephrine (Levophed), isoproterenol hydrochloride (Isuprel), and epinephrine are the pressor agents of choice. Immediate thrombolysis is the standard of care for any patient with significant hypoxemia or hypotension due to proven pulmonary embolism. Beyond this, the potential benefit of using thrombolytic agents should be considered routinely for every patient with proven pulmonary embolism. Surgical embolectomy is useful for unstable pulmonary embolism when there are absolute contraindications to thrombolysis or when thrombolytic therapy fails. Empirical use of thrombolysis may be considered as a last-ditch effort for a critically ill patient when there is a high clinical suspicion of pulmonary embolism. Standard closed-chest cardiopulmonary resuscitation is ineffective when the pulmonary circulation is obstructed by thrombus.

Control echocardiograms were performed 12 h after the initiation of treatment and at 12-month follow-up. Three patients died before the onset of thrombolytic infusion. The nine remaining patients were submitted to thrombolytic therapy using rt-PA. In seven of the nine remaining patients, MRHT was no longer observed after 12 h and the echocardiographic signs of RV overload had disappeared. The two last patients required adjunctive surgery because of evidence of persistent thrombus in a pulmonary artery. After 24 h, both scintigraphy and angiography demonstrated improved pulmonary perfusion. At 1-year follow-up, all patients were alive and the pulmonary artery pressure estimated by Doppler echocardiography was &lt;30 mm Hg. The incidence of right heart thrombus is low in patients admitted for acute PE. Thrombolytic therapy with rt-PA appears to be rapidly effective in most patients with MRHT.

A total of 420 patients with acute respiratory symptoms and positive findings on chest radiograph were evaluated from December 2008 to December 2009. The subjects were referred to outpatient clinics or emergency departments of Birjand's medical university hospitals, Iran, and were enrolled as positive cases. A checklist was completed for each patient including their demographic information, clinical signs and symptoms (cough, sputum production, dyspnea, chest pain, fever, tachycardia, and tachypnea), abnormal findings in pulmonary auscultation and laboratory findings (erythrocyte sedimentation rate, C-reactive protein levels, and white blood cell count). An equal number of age-matched individuals with acute respiratory symptoms, but insignificant findings on chest radiography, were included as the control group. Finally, the diagnostic values of different findings were compared. The data showed that vital signs and physical examination findings are useful screening parameters for predicting chest radiograph findings in outpatient settings. Therefore, by implementing a prediction rule, we would be able to determine which patients would benefit from a chest X-Ray (sensitivity, 94% and specificity, 57%). This study's findings suggest that requesting chest radiographs might not be necessary in patients with acute respiratory symptoms unless the vital signs and/or physical examination findings are abnormal.

His family physician suspected febrile tracheobronchitis and treated it with ampicillin for 5 days. Because symptoms persisted an ECG was done which suggested acute myocardial infarction. The patient underwent an emergency coronary angiography which excluded coronary artery disease and aortic dissection. Pericarditis was suspected and the patient put on aspirin, 500 mg/d. Because of persisting cardiac symptoms an echocardiography was performed which revealed systolic separation between epi- and pericardium, characteristic of a small pericardial effusion after acute pericarditis. The symptoms improved after one week of treatment with diclofenac and the ECG had become normal. Two months later the patient was seen at our cardiac outpatient clinic. He had night sweats, sporadic precordial pain and severe dyspnoe. Further investigations revealed tachycardia (120/min), hypotension (95/70 mm Hg), pulsus paradoxus and jugular vein sustension. Echocardiography revealed a large pericardial effusion (\"swinging heart\"), which explained the low voltage and the electrical alternans in the ECG. Pericardiocentesis was carried out the same day to relieve the tamponade. It was followed by pericardioscopy and epi- as well as pericardial biopsy. 485 ml of a serous effusion were drained. Cytology and histology demonstrated a lymphocytic fibrinous pericarditis. Polymerase chain reaction (PCR) on viral and bacterial RNA and DNA of potentially cardiotropic agents remained negative. The pigtail catheter was left in place and 80 mg of gentamycin were given intrapericardially on day 1 and 2, followed by 500 mg of crystalloid triamcinolone acetate after the PCR was found to be negative. Oral treatment with 0.5 mg colchicine three times a day (off-label use) was started and maintained for 6 months. After 9 months no effusion was detected and the patient was free of symptoms. After exclusion of bacterial and viral pericardial infection, a high single dose of intrapericardial triamcinolone combined with long-term oral colchicine has proven to be a highly efficacious treatment of autoreactive pericarditis which will avoid relapses in most cases." }, { "id": "pubmed23n0495_3220", "title": "Cases from the Osler Medical Service at Johns Hopkins University.", "score": 0.015966921119592876, "content": "PRESENTING FEATURES: A 70-year-old African American man was admitted with a history of fever, chills, and malaise of several days' duration.

[17] [18] Typically, symptoms begin at the age of 50 to 70 years in patients with the bicuspid aortic valve and in greater than 70 years in patients with tri-leaflet valve calcific stenosis. Patients progressively experience a gradual decrease in exercise tolerance, dyspnea on exertion, and fatigue. Severe exertional dyspnea, paroxysmal nocturnal dyspnea, orthopnea, and pulmonary edema show various degrees of pulmonary venous hypertension. Angina results from the combination of the need for increased oxygen in hypertrophied myocardium and reduction of oxygen delivery secondary to the excessive compression of coronary vessels. Syncope is caused by the decrease in cerebral perfusion occurring during exertion when the arterial pressure declines due to systemic vasodilation and an inadequate increase in cardiac output related to stenosis. It is also due to the malfunction of the baroreceptor mechanism in severe aortic stenosis. Non-cardiac symptoms include gastrointestinal (GI) bleeding and cerebral emboli. GI bleeding is observed in patients with severe aortic stenosis and is often associated with angiodysplasia or other vascular malformations. It manifests from shear stress-induced platelet aggregation and reduction in the von Willebrand factor. [19] Cerebral emboli occur due to microthrombi formation on thickened bicuspid valves. There is also an observed increase in the risk of infective endocarditis in patients with aortic valve disease, especially with a bicuspid valve. On examination, carotid upstroke can be observed on palpation. A slow-rising, late-peaking, and a low-amplitude carotid impulse, pulsus parvus et tardus, is an expected finding in severe aortic stenosis and, when present, is specific to aortic stenosis.

It develops insidiously, and in many cases, particularly in developed countries, no antecedent diagnosis can be found. These cases are termed idiopathic. Tuberculosis is the leading cause of constrictive pericarditis in developing nations but represents only a small minority in developed countries. Here the authors describe two different case reports where tuberculosis was the probable cause of CCP. A 21-year-old man born in Cape Verde living in Europe for 4 years and a 24-year-old man born in Guiné Bissau were both admitted due to intense precordial pain and syncope after exertion. Interestingly both had fatigability, dyspnea, chest discomfort and palpitations on exertion, as well as progressive involuntary weight loss and decubitus cough. On physical examination they had tachycardia, jaundice, cachexia, elevated jugular venous pressure, hepatomegaly and ascites. Both electrocardiograms showed prominent P waves and chest X-ray showed bilateral pulmonary interstitial infiltrates and enlargement of the right cavities. Analytically, elevated bilirubin, leukopenia and thrombocytopenia was also found in both. Echocardiography revealed findings, in both cases, compatible with CCP including less common signs as annulus reversus and annulus paradoxus. Thoraco-abdomino-pelvic CT from both patients revealed chronic liver disease with congestion, pleural effusion, pericardial calcifications, ascites and massive mediastinal and abdominal adenopathies. Blood cultures and IGRA test were negative. However, given the presumptive diagnosis of tuberculosis (TB), anti-TB therapy was started. Despite the diagnosis of \"end-stage\" CCP with very high operative risk multidisciplinary team decided after informed consent, to perform total anterior pericardiectomy, that occurred without complications. Pericardial and mediastinal biopsies, pericardial/pleural fluid cultures/ immune-phenotyping were inconclusive. Anti- tuberculosis therapy was maintained. After surgery, the patients had a remarkable clinical improvement (NYHA I) that persisted in 6- month follow-up. These two case reports illustrate that despite the markedly elevated operative risk of pericardiectomy in \"end-stage\" forms of disease after patients informed consent must be a considered option.

In short stature, the decision to perform a genetic test is taken depending on clinical, paraclinical and imaging signs. In case of a short stature associated with a low weight/length for gestational age, genetic testing is proposed to evaluate a Russell-Silver syndrome or if the short stature is associated with other clinical signs (e.g. intellectual disability), chromosomal analysis by microarray is proposed. If the short stature is disproportionate, it is indicated to perform a next generation sequencing (NGS) of a panel of genes involved in skeletal dysplasia. If an endocrine cause for short stature is observed at the hormonal evaluation, it is indicated to test a panel of genes involved in these pathways. In genetic obesity, depending on clinical signs associated to obesity, it will be a more targeted genetic testing.

Thus, anti-GBM glomerulonephritis was diagnosed. After treatment with prednisone, oral cyclophosphamide and plasmapheresis, chest X-ray and hemoptysis improved, but renal failure persisted. Anti-GBM antibodies were negative. 4 weeks later, the patient presented again with a clinical relapse of severe hemoptysis and respiratory insufficiency after smoke exposition. Despite negative anti-GBM antibodies, he was treated similarly to a relapse and after the second course of plasmapheresis the patients' general condition improved and hemoptysis subsided. During the next 10 months the patient was stable with negative antibodies. He was under intermittent hemodialysis until laboratory measurements showed improved renal function. Now, 30 months after the acute episode, the patient is off dialysis for 17 months with stable creatinine values of 1.9 - 2.4 mg/dl, and is currently being treated with antihypertensive medicaments, calcitriol, calciumacetate, natriumhydrogencarbonate and allopurinol. The prognosis of anti-GBM glomerulonephritis depends on serum creatinine and the need of dialysis at initial presentation. In these patients, one-year survival rate is 67% and 5% for kidney function. Of note, despite the unfavorable prognosis in our patient, renal function recovered after 1 year of hemodialysis treatment. It is important to consider that in patients with anti-GBM disease antibody-negative relapses are possible." }, { "id": "pubmed23n1041_23469", "title": "Nephrotic syndrome due to minimal-change disease superimposed on anti-glomerular basement membrane antibody positive glomerulonephritis; a case report.", "score": 0.018672919923571306, "content": "The prognosis for renal function in anti-GBM glomerulonephritis (anti-GBM GN) is extremely poor, and when renal impairment progresses severely, it is difficult to expect improvement. In addition, it is also known that once the disease activity can be controlled by aggressive treatment, its recurrence is rare. We experienced an anti-GBM GN that improved from severe renal dysfunction and relapsed. A possible cause was the superimpose of nephrotic syndrome due to minimal change disease (MCD). A 30-year-old man was admitted to our hospital because of general malaise, fever, oliguria and renal dysfunction. The patient's laboratory data showed serum creatinine as high as 6.6 mg/dl, and severe inflammation (C-reactive protein 20.6 mg/dl). Anti-glomerular basement membrane antibody (anti-GBM Ab) was detected in his serum, which led to the diagnosis of anti-GBM GN. Treatment was initiated with high-dose glucocorticoid (GC) and plasma exchange therapy (PE), and the patient's renal function and oliguria improved rapidly and he was discharged 40 days after admission. Renal biopsy findings showed cellular crescents associated with linear IgG depositions along the glomerular tufts compatible with anti-GBM GN, but only about one-third of the glomeruli was involved, suggesting that it still remains an early stage of the disease. However, 2 months after discharge, he had a relapse and was readmitted due to severe proteinuria with positive anti-GBM Ab. On the second admission, after high-dose GC and PE combined with intravenous cyclophosphamide, and remission was achieved. Despite the relatively minor renal biopsy findings, the patient showed rapid renal dysfunction and relatively rapid improvement with our treatment. Electron microscopy of the renal biopsy tissue showed significant foot process effacement on podocytes in the apparently normal glomeruli, without electron dense deposits. On the basis of clinical course and renal pathology, it is suggested that the present case was a rare complication of an early stage of anti-GBM GN and minimal change nephrotic syndrome.

An analytical study showed normocytic normochromic anemia with a hemoglobin level of 7.2 g/dL and leukocytosis with normal renal function and coagulation times. A blood transfusion was performed without complications. Chest computed tomography revealed a reticulonodular infiltrate of both lungs. Bronchoscopy showed no apparent lesions. Sputum cultures, rapid urine antigens for Legionella pneumophila and Streptococcus pneumoniae, studies for Influenza, virologic markers and serologic studies for autoimmunity were all negative. At the end of the tenth day his general state deteriorated with fatigue, hematuria, and in 3 days he developed aggravation of renal function with recurrent hemoptysis and anemia. Immunosuppression with daily prednisolone 1 g administered intravenously was initiated. An urgent bronchoscopy showed no lesions. A kidney biopsy showed fibrinoid necrosis and cellular crescents. Immunofluorescence revealed a linear immunoglobulin G deposition compatible with Goodpasture's syndrome. Immunosuppressive therapy with daily cyclophosphamide 120 mg orally was added. Subsequently he was transferred to a referral center at which 21 sessions of plasmapheresis and four sessions of hemodialysis were performed with good response; he currently has no need of hemodialysis. The absence of circulating anti-glomerular basement membrane antibodies in Goodpasture's syndrome adds complexity to the diagnosis creating an unusual setting in a rare disease. In our case a kidney biopsy was essential for diagnosis and clinical approach.

Therefore, we present a case of Goodpasture syndrome that presented with nephrotic-range proteinuria and was seronegative for anti-GBM antibodies. A 38-year-old Chinese man presented with a lung lesion that was discovered by physical examination a month prior to presentation. The chief concern was occasional hemoptysis without fever, cough, chest pain, and edema. Laboratory testing revealed that the urinary protein level and urine erythrocyte count were 7.4 g/24 hours and 144/high-power field (HPF), respectively. Serological testing for anti-GBM antibodies was negative. Chest computed tomography revealed multiple exudative lesions in both lungs, indicating alveolar infiltration and hemorrhage.

However, kidney biopsy suggested cellular crescent formation and segmental necrosis of the globuli, with linear IgG and complement C3 deposition on the GBM. These findings were consistent with the diagnosis of anti-GBM antibody nephritis. The patient underwent 7 sessions of double filtration plasmapheresis. He was also administered with intravenous methylprednisolone and cyclophosphamide. After renal function stabilization, he was discharged under an immunosuppressive regimen comprising of glucocorticoids and cyclophosphamides.

Indeed, the physical examination shows a Tanner stage IV, with no growth of pubic or axillary hair. The external genitalia are normal. Ultrasonography reveals a small uterus and radiology reveals a bone age of 3 years. What attitude should be adopted?

Following is a case of a 17 year old with immune thrombocytopenic purpura (ITP), POF, 47, XXX and a positive antinuclear antibody (ANA).Case Report: A 17 year old Caucasian female was referred to the Adolescent Health Clinic for evaluation of oligomenorrhea with secondary amenorrhea. Thelarche occurred at 12 years, and menarche at 13 years of age. Since then she had a total of five menstrual periods, spaced 1-15 months apart and lasting 3-5 days. Her last menstrual period was six months prior to presentation. Past medical history was significant for chronic ITP diagnosed seven months prior to presentation, when she developed easy bruising. She was treated with IV gamma globulin and had a moderate response, but relapsed several weeks later. She was started on oral prednisone and had a good response, but continued to relapse whenever steroids were tapered. She was therefore maintained on prednisone 10 mg QOD. There was no family history of irregular menses or autoimmune disease. Physical exam revealed a well-appearing, slightly Cushingoid 17 year old. Physical and cognitive development were age-appropriate. There were no stigmata of Turner Syndrome. The thyroid was normal. Breasts were Tanner 5; public hair was Tanner 3. The external genitalia were normal and appeared well-estrogenized. The remainder of the exam was unremarkable. Pelvic ultrasound demonstrated a normal uterus and ovaries. Laboratory evaluation was significant for elevated gonadotropins and nondetectable estradiol. ANA was positive at 1:320 with a speckled pattern. Blood counts, serologies, complement levels, and coagulation studies were otherwise normal. Cytogenetic studies revealed a 47,XXX karyotype.

The disorder is included under anxiety disorders because it shares some obsessive-compulsive features. Patients have the tendency towards feelings of unattractiveness, body dissatisfaction, and low self-esteem (1,2). It is a major psychiatric problem, but many patients with this disorder first present to a dermatologist. An 11-year-old girl came to our department with a 2-month history of diffuse hair loss on the frontoparietal and parietotemporal area (Figure 1). She had originally been examined by a pediatrician with the diagnosis of alopecia areata. The patient`s personal history included hay fever and shortsightedness, and she suffered from varicella and mononucleosis. Nobody in the family history suffered from alopecia areata, but her father has male androgenetic alopecia (Norwood/Hamilton MAGA C3F3). The mother noticed that the child had had changeable mood for about 2 months and did not want to communicate with other persons in the family. The family did not have any pet at home. At school, her favorite subjects were Math and Computer Studies. She did not like Physical Education and did not participate in any sport activities during her free time. This was very strange because she was obese (body-mass index (BMI) 24.69). She was sometimes angry with her 13-year-old sister who had better results at school. The girl had suddenly started to wear a blue scarf. The parents did not notice that she pulled out her hair at home. Dermatological examination of the capillitium found a zone of incomplete alopecia in the frontoparietal and parietotemporal area, without inflammation, desquamation, and scaring. Hairs were of variable length (Figure 1). There was a patch of incomplete alopecia above the forehead between two stripes of hair of variable length (Figure 2). The hair pull test was negative along the edges of the alopecia. Mycological examination from the skin capillitium was negative. The trichoscopy and skin biopsy of the parietotemporal region of the capillitium (Figure 3) confirmed trichotillomania. Laboratory tests (blood count, iron, ferritin, transferrin, selenium, zinc, vitamin B12, folic acid, serology and hormones of thyroid gland) were negative. We referred the girl for ophthalmologic and psychological examination. Ophthalmologic examination proved that there was no need to add any more diopters. The psychological examination provided us with a picture in which she drew her family (Figure 4). The strongest authority in the family was the mother because she looked after the girls for most of the day. She was in the first place in the picture. The father had longer working hours and spent more time outside the home. He worked as a long vehicle driver. He was in the second place in the picture. There was sibling rivalry between the girls, but the parents did not notice this problem and preferred the older daughter. She was successful at school and was prettier (slim, higher, curly brown hair, without spectacles). Our 11-years-old patient noticed all these differences between them, but at her level of mental development was not able to cope with this problem. She wanted to be her sister's equal. The sister is drawn in the picture in the third place next to father, while the patient's own figure was drawn larger and slim even though she was obese. Notably, all three female figures had very nice long brown hair. It seemed that the mother and our patient had better quality of hair and more intense color than the sister in the drawing. The only hairless person in the picture was the father. The girl did not want to talk about her problems and feelings at home. Then it was confirmed that our patient was very sensitive, anxious, willful, and withdrawn. She was interested in her body and very perceptive of her physical appearance. From the psychological point of view, the parents started to pay more interest to their younger daughter and tried to understand and help her. After consultation with the psychiatrist, we did not start psychopharmacologic therapy for trichotillomania; instead, we started treatment with cognitive behavioral therapy, mild shampoo, mild topical steroids (e.g. hydrocortisone butyrate 0.1%) in solution and methionine in capsules. With parents' cooperation, the treatment was successful. The name trichotillomania was first employed by the French dermatologist Francois Henri Hallopeau in 1889, who described a young man pulling his hair out in tufts (3-5). The word is derived from the Greek thrix (hair), tillein (to pull), and mania (madness) (5). The prevalence of TTM in the general adult population ranges from 0.6% to 4%, and 2-4% of the general psychiatric outpatient population meet the criteria for TTM (2-5). The prevalence among children and adolescents has been estimated at less than 1% (5). The disease can occur at any age and in any sex. The age of onset of hair pulling is significantly later for men than for women (3). There are three subsets of age: preschool children, preadolescents to young adults, and adults. The mean age of onset is pre-pubertal. It ranges from 8 to 13 years (on average 11.3 years) (2-5). The occurrence of hair-pulling in the first year of life is a rare event, probably comprising &lt;1% of cases (5). The etiology of TTM is complex and may be triggered by a psychosocial stressor within the family, such as separation from an attachment figure, hospitalization of the child or parent, birth of a younger sibling, sibling rivalry, moving to a new house, or problems with school performance. It has been hypothesized that the habit may begin with \"playing\" with the hair, with later chronic pulling resulting in obvious hair loss (2). Environment is a factor because children usually pull their hair when alone and in relaxed surroundings. The bedroom, bathroom, or family room are \"high-risk\" situations for hair-pulling (5). Men and women also differed in terms of the hair pulling site (men pull hair from the stomach/back and the moustache/beard areas, while women pull from the scalp) (3). Pulling hair from siblings, pets, dolls, and stuffed animals has also been documented, often occurring in the same pattern as in the patient (5). Genetic factors contributing to the development of TTM are mutations of the SLITRK1 gene, which plays a role in cortex development and neuronal growth. The protein SAPAP3 has been present in 4.2% of TTM cases and patients with obsessive-compulsive disorder (OCD). It may be involved in the development of the spectrum of OCD. A significantly different concordance rate for TTM was found in monozygotic (38.1%) compared with dizygotic (0%) twins in 34 pairs (3). The core diagnostic feature is the repetitive pulling of hairs from one`s own body, resulting in hair loss. The targeted hair is mostly on the scalp (75%), but may also be from the eyebrows (42%), eyelashes (53%), beard (10%), and pubic area (17%) (3,5). There are three subtypes of hair pulling - early onset, automatic, and focused. Diagnostic criteria for TTM according to DSM-IV criteria are (2,3,5): 1) recurrent pulling of one`s hair resulting in noticeable hair loss; 2) an increasing sense of tension immediately prior to pulling out the hair or when attempting to resist the behavior; 3) pleasure, gratification, or relief when pulling out the hair; 4) the disturbance is not better accounted for by another mental disorder and is not due to a general medical condition (e.g., a dermatologic condition); 5) the disturbance causes clinically significant distress or impairment in social, occupational, or other important areas of functioning. The differential diagnosis includes alopecia areata (Table 1) (6), tinea capitis, telogen effluvium, secondary syphilis, traction alopecia, loose anagen syndrome, lichen planopilaris, alopecia mucinosa, and scleroderma (2-5). Biopsy of an involved area (ideally from a recent site of hair loss) can help to confirm the diagnosis (5). On histologic examination, there are typically increased numbers of catagen and telogen hairs without evidence of inflammation. Chronic hair pulling induces a catagen phase, and more hairs will be telogen hairs. Pigment casts and empty anagen follicles are often seen. Perifollicular hemorrhage near the hair bulb is an indicator of TTM (2). Complications of TTM are rare, but they comprise secondary bacterial infections with regional lymphadenopathy as a result of picking and scratching at the scalp. Many patients play with and ingest the pulled hairs (e.g. touching the hair to lips, biting, and chewing). Trichophagia (ingestion of the hair) can lead to a rare complication named trichobezoar (a \"hair ball\" in stomach). This habit is present in approximately 5% to 30% of adult patients, but it is less frequent in children. Patient with trichophagia present with pallor, nausea, vomiting, anorexia, and weight loss. Radiologic examination and gastroscopy should not be delayed (2,4,5). The management of the disease is difficult and requires strong cooperation between the physician, patient, and parents. The dermatologist cannot take part in the therapy, strictly speaking, but without the psychological, psychopharmacologic, and topic dermatologic treatment a vicious circle will be perpetuated.

She underwent parathyroidectomy at 24 weeks of gestation with removal of a large left inferior parathyroid adenoma which normalized her serum calcium. Multipoint linkage from a genome-wide screen has identified a region of suggestive linkage on chromosome 2p13.3-14 in some cases of familial isolated hyperparathyroidism (FIHP). To our knowledge, this is the first case of primary amenorrhoea due to reciprocal translocation involving chromosome 2 and the X chromosome associated with PHPT. PHPT in this case is most likely to be as a result of chromosome 2 involvement where a locus for FIHP has been identified.

Here we report on the case of a girl with a rare 45X0/47XXX mosaic TS exhibiting a precocious puberty. The patient was diagnosed with TS at the age of 4 years, upon a diagnostic work-up for dysmorphic features. Chromosome analysis revealed a mosaic karyotype (45X0/47XXX). She presented with normal height and normal growth velocity so that Growth Hormone (GH) therapy was not started. She was referred to our Department at the age of 7 years and 10 months, because of vaginal bleeding. A physical examination revealed a Tanner stage III for breast and Tanner stage III for pubic hair development. Height and weight were within the normal range for age. Psychological evaluation showed moderate global developmental delay, together with emotional and social immaturity and reading difficulties. The growth rate was accelerated. Her bone age was 10 years. Pelvic ultrasound demonstrated increased size for age of both the uterus and the ovaries, with bilateral ovarian follicles. GnRH stimulation test revealed pubertal response of gonadotropins (peak LH 22.5 mIU/ml). MRI of the brain was normal. These clinical, radiologic and laboratory findings were consistent with a diagnosis of idiopathic central precocious puberty; therefore, GnRH analog therapy was started, in order to slow pubertal progression and to preserve adult stature. Furthermore, GH treatment was added to further improve adult height. Our case highlights the possibility of precocious puberty as an atypical clinical feature of TS. Thus, precocious puberty may occur in TS girls when a dosage compensation by the cell line with more than two X chromosomes allows normal ovarian function.

An endocrinological test and rhythm analyses of ambulatory blood pressure (ABP) and heart rate variability in a case suggested possible association between hypnic headache and hypothalamic-pituitary dysfunction. Case 1: A 48-year-old female migraineur complained of new-onset nocturnal headaches. Her headache awakened her from sleep between 1 AM and 2 AM. The headache occurred 3-4 times per week and lasted from 1 hour to 2 hours. The headache were moderate intensity and bilateral dull throbbing pain that located in the forehead to temples. There was no accompanying symptoms such as nausea, phonophobia, photophobia, nor the other autonomic features including conjunctival injection or tearing during the headache attacks. Physical and neurological examinations showed normal results except slight weakness and mild dysesthesia of the left arm due to a vertebral disk herniation at C5/6 level. In the pituitary endocrinological test, the prolactin level remarkably increased in response to the TRH loading. The single cosinor analysis demonstrated significant circadian rhythm of ABP parameters. However, the analysis did not demonstrate any significant circadian rhythm of Holter ECG parameters of time domain analysis and frequency analysis. Receiving 200 mg lithium bicarbonate before sleep, her nocturnal headache completely disappeared. Case 2: A 68-year-old woman had been followed up by her chronic tension-type headache since her forties. At her 66-years, she suffered from a new nocturnal headache. She awoke from sleep by the headache about 3 AM and the headache lasted 30 min. Moderate, dull headache located on her left temple to parietal head, 3-4 times/week. She was able to go back asleep without any medication after spontaneous headache cessation. She first complained the nocturnal headache at the 10 months later of the new headache appearance. She received 200 mg caffeine just before sleep and her headache has been disappeared. Case 3: 70-year-old women had been regularly visited our clinics for her migraine and chronic tension-type headache. She received amitriptyline and her headaches was well controlled. At her 69 years, she complained nocturnal headache. It occured every other day. The headache was moderate pulsative dull pain on the occipital region and lasted 90 minutes without any autonomic symptoms. Headache began between midnight and 1 AM. She told us her new nocturnal headache one year later of the onset. Oral caffeine (200 mg) just before sleep did not improve her headache and caused insomnia. Receiving 100 mg lithium before sleep, her hypnic headache disappeared completely. These three cases are compatible with the diagnostic criteria proposed in ICHD-II.

One main differentiating factor is the duration of painful attacks. While attacks typically last 5 s to 10 min in SUNCT syndrome (short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing), paroxysmal hemicrania lasts 2-30 min and cluster headaches 15-180 min. Hemicrania continua represents a continuous TAC variant. From a therapeutic view, TACs differ substantially. Lamotrigine is used as first-choice prevention in SUNCT syndrome and indometacin in paroxysmal hemicrania. For cluster headaches, acute therapy with inhaled pure oxygen and fast-acting triptans (sumatriptan s.c. and intranasal zolmitriptan) is equally important to short-term preventive therapy with methysergide and cortisone and long-term prophylactic treatment comprising verapamil as drug of first choice and lithium carbonate and topiramate as drugs of second choice.

Cluster headache attacks are accompanied by ipsilateral autonomic symptoms such as ptosis, miosis, redness or flushing of the face, nasal congestion, rhinorrhoea, peri-orbital swelling and/or restlessness or agitation. Cluster headache treatment entails fast-acting abortive treatment, transitional treatment and preventive treatment. The primary goal of prophylactic and transitional treatment is to achieve attack freedom, although this is not always possible. Subcutaneous sumatriptan and high-flow oxygen are the most proven abortive treatments for cluster headache attacks, but other treatment options such as intranasal triptans may be effective. Verapamil and lithium are the preventive drugs of first choice and the most widely used in first-line preventive treatment. Given its possible cardiac side effects, electrocardiogram (ECG) is recommended before treating with verapamil. Liver and kidney functioning should be evaluated before and during treatment with lithium. If verapamil and lithium are ineffective, contraindicated or discontinued because of side effects, the second choice is topiramate. If all these drugs fail, other options with lower levels of evidence are available (e.g. melatonin, clomiphene, dihydroergotamine, pizotifen). However, since the evidence level is low, we also recommend considering one of several neuromodulatory options in patients with refractory chronic cluster headache. A new addition to the preventive treatment options in episodic cluster headache is galcanezumab, although the long-term effects remain unknown. Since effective preventive treatment can take several weeks to titrate, transitional treatment can be of great importance in the treatment of cluster headache.

In cluster headache there is often a considerable diagnostic delay - an average of 7 years in a population-based survey. Cluster headache is characterized by very severe or severe orbital or periorbital pain with a duration of 15-180 minutes. The cluster headache attacks are accompanied by characteristic associated unilateral symptoms such as tearing, nasal congestion and/or rhinorrhoea, eyelid oedema, miosis and/or ptosis. In addition, there is a sense of restlessness and agitation. Patients may have up to eight attacks per day. Episodic cluster headache (ECH) occurs in clusters of weeks to months duration, whereas chronic cluster headache (CCH) attacks occur for more than 1 year without remissions. Management of cluster headache is divided into acute attack treatment and prophylactic treatment. In ECH and CCH the attacks can be treated with oxygen (12 L/min) or subcutaneous sumatriptan 6 mg. For both oxygen and sumatriptan there are two randomized, placebo-controlled trials demonstrating efficacy. In both ECH and CCH, verapamil is the prophylactic drug of choice. Verapamil 360 mg/day was found to be superior to placebo in one clinical trial. In clinical practice, daily doses of 480-720 mg are mostly used. Thus, the dose of verapamil used in cluster headache treatment may be double the dose used in cardiology, and with the higher doses the PR interval should be checked with an ECG. At the start of a cluster, transitional preventive treatment such as corticosteroids or greater occipital nerve blockade can be given. In CCH and in long-standing clusters of ECH, lithium, methysergide, topiramate, valproic acid and ergotamine tartrate can be used as add-on prophylactic treatment. In drug-resistant CCH, neuromodulation with either occipital nerve stimulation or deep brain stimulation of the hypothalamus is an alternative treatment strategy. For most cluster headache patients there are fairly good treatment options both for acute attacks and for prophylaxis. The big problem is the diagnosis of cluster headache as demonstrated by the diagnostic delay of 7 years. However, the relatively short-lasting attack of pain in one eye with typical associated symptoms should lead the family doctor to suspect cluster headache resulting in a referral to a neurologist or a headache centre with experience in the treatment of cluster headache." }, { "id": "pubmed23n0299_4940", "title": "[Cluster-tic syndrome: two case reports].", "score": 0.014266435319066899, "content": "Two patients with cluster-tic syndrome are reported.

Treatment of this condition is difficult; many drugs and surgical procedures have been tried with variable results. In the literature, two cases have been described with short-term response to microvascular decompression of the trigeminal root. We present the case of a patient with short-lasting unilateral neuralgiform headache with conjunctival injection and tearing syndrome who remains asymptomatic 2 years after microvascular decompression. A 56-year-old woman was referred to our clinic because she had experienced pain in the distribution of the first left trigeminal branch during the previous 2 years. She experienced paroxysms lasting from a few seconds to 1 to 2 minutes superimposed over a dull sensation of pain involving the same territory. The paroxysms had no refractory period and were triggered by touching the eye or the left side of the face, chewing, yawning, washing her hair, and even by light. Although the paroxysms were triggered by light touch or chewing, she was able to talk or touch herself while having the paroxysm. During pain attacks, she experienced tearing and ipsilateral conjunctival injection, eyelid edema and rhinorrhea, as well as intense photophobia. A magnetic resonance imaging scan revealed a vascular structure distorting and compressing the trigeminal root. The patient underwent microvascular decompression of the trigeminal root. At surgery, there was clear compression of the trigeminal root by a superior cerebellar artery loop that was resolved by interposing a Teflon patch. The patient awoke from the operation without pain, and all the accompanying signs and symptoms, such as photophobia, disappeared. The postoperative course was uneventful, and 2 years after treatment, the patient remains asymptomatic. Microvascular decompression could be an alternative therapeutic approach to this rare syndrome." }, { "id": "pubmed23n0388_5817", "title": "Episodic paroxysmal hemicrania with seasonal variation: case report and the EPH-cluster headache continuum hypothesis.", "score": 0.009523809523809525, "content": "Episodic paroxysmal hemicrania (EPH) is a rare disorder characterized by frequent, daily attacks of short-lived, unilateral headache with accompanying ipsilateral autonomic features.

We report a new case of EPH with a clear seasonal pattern: a 32-year-old woman with a right-sided headache for 17 years. Pain occurred with a seasonal variation, with bouts lasting one month (usually in the first months of the year) and remission periods lasting around 11 months. During these periods she had headache from three to five times per day, lasting from 15 to 30 minutes, without any particular period preference. There were no precipitating or aggravating factors. Tearing and conjunctival injection accompanied ipsilaterally the pain. Previous treatments provided no pain relief. She completely responded to indomethacin 75 mg daily.

A 34 year old man with a past history of a similar but briefer episode 5 years previously presented to us. He complained of repeated episodes of stabbing pain with no obvious cause. The pain started at the base of the neck and radiated along the right carotid vessels to the cheek, base of the nose and ipsilateral eye. This was accompanied by injection of the conjunctivae, tears, nasal congestion and nasal discharge. Each episode lasted 15 to 30 minutes and was repeated 20 to 25 times a day without any particular relation to the time of day. The neurological examination, MR and angio-MR were normal. Before being seen by us he had been treated with prednisone and verpamil without effect. Indomethacin at a dose of 100 mg/day controlled the problem completely.

For the majority headache will represent a minor annoyance to be endured or treated with any available drug in the medicine chest. For some, migraine headaches or tension-type headaches become entwined with every daily activity. With the advent of modern pharmacology, headache can often be treated successfully. Trigeminal neuralgia is a source of particularly high morbidity among the elderly, but may be treated very satisfactorily with carbamazepine or baclofen. Paroxysmal hemicrania is exquisitely sensitive to indomethacin, while cluster headache patients receive relief from oxygen inhalation, corticosteroids or lithium. Headache may be the signature of the disease which leads to serious morbidity and mortality. The 'sentinel' headache of subarachnoid haemorrhage is evaluated by a physician in 15% of patients who will eventually rupture an intracranial aneurysm. Morning headache with nausea and vomiting may represent increased intracranial pressure caused by a tumour, haematoma or abscess. The elderly patient with a new headache needs emergency evaluation for temporal arteritis and rapid corticosteroid treatment if the diagnosis is confirmed, to prevent blindness.

Transient amnesia always occurred during lessons. Suddenly he didn't know where he was or what he was speaking about. Episodes lasted one minute. After them, he had no confusion and no difficulty in concentration but intense anxiety. In an another hand, when he was in his car, after lessons, he could forget where he was during some minutes.

He told us checking obsessive compulsive disorder during since long time ago. We discussed clear differences which existed between seizure and ruminations or preoccupations. Secondly, a 55-year-old woman was afraid of her memory performances. She was medical secretary and had no problem in her work but she would like a memory consultation to reassure herself. She was neither depressed nor anxious. She presented curious production in fluency task. She had to produce as many animals's names as possible: she could say 35 names which was an excellent performance but only in alphabetic order! Neuropsychological tests objectived impairment in her first free recall of Grober and Buschke's words. She tried in her first free recall to remember words in alphabetic order. She explained how she was bound to range everything in alphabetic order! She had a lot of rituals. She thought that she had an obsessive compulsive disorder but never consulted about this.

Physical examination showed a febrile patient (38.8 degrees C) with right facial paresis and trismus. A hyperemic, hard and tender swelling was observed in his right neck from the lateral cervical to the mental region. The tympanic membrane was invisible because of granulation and swelling of the posterior wall of the external auditory canal. Intravenous clindamycin and ceftazidime therapy was started immediately.

This article aimed to provide an update on the evaluation, diagnosis, and treatment of tinea capitis. A PubMed search was performed in Clinical Queries using the key term \"tinea capitis\". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature. The information retrieved from the above search was used in the compilation of the present article. Patents were searched using the key term \"tinea capitis\" at www.freepatentsonline.com. Tinea capitis is most often caused by Trichophyton tonsurans and Microsporum canis. The peak incidence is between 3 and 7 years of age. Non-inflammatory tinea capitis typically presents as fine scaling with single or multiple scaly patches of circular alopecia (grey patches); diffuse or patchy, fine, white, adherent scaling of the scalp resembling generalized dandruff with subtle hair loss; or single or multiple patches of well-demarcated area (s) of alopecia with fine-scale, studded with broken-off hairs at the scalp surface, resulting in the appearance of \"black dots\". Inflammatory variants of tinea capitis include kerion and favus. Dermoscopy is a highly sensitive tool for the diagnosis of tinea capitis. The diagnosis can be confirmed by direct microscopic examination with a potassium hydroxide wetmount preparation and fungal culture. It is desirable to have mycologic confirmation of tinea capitis before beginning a treatment regimen. Oral antifungal therapy (terbinafine, griseofulvin, itraconazole, and fluconazole) is considered the gold standard for tinea capitis. Recent patents related to the management of tinea capitis are also discussed. Tinea capitis requires systemic antifungal treatment. Although topical antifungal therapies have minimal adverse events, topical antifungal agents alone are not recommended for the treatment of tinea capitis because these agents do not penetrate the root of the hair follicles deep within the dermis. Topical antifungal therapy, however, can be used to reduce transmission of spores and can be used as adjuvant therapy to systemic antifungals. Combined therapy with topical and oral antifungals may increase the cure rate." }, { "id": "pubmed23n0354_18608", "title": "Generalized pruritus without primary lesions.

Dermatobia hominis is a common cause of myiasis in Central- and South-America and should be taken into account in furuncular skin eruptions of returning travelers. The typical appearance of the skin eruption with a central porus, seropurulent discharge and a whitish, tender moving mass within the nodule is quite characteristic for myiasis.

It is a highly distressing disease that affects young and middle-aged adults, with a slight male predominance (1). The most frequent clinical manifestations are follicular pustules and diffuse and perifollicular erythema that heal with centrifugal scarring. Follicular tufting, erosions, and hemorrhagic crusts can also be present, and this alopecia is most often located at the vertex and occipital area. Patients frequently complain about pain, itching, or burning sensations, and the involvement of other body areas is rare (2). The pathogenesis of this disease remains unclear. Staphylococcus aureus and other hair follicle bacteria can often be isolated from the pustules, suggesting the role of a bacterial infection in its etiology. A defect in the host's immune response can also be postulated by reports of familial cases and the appearance of FD in patients with immunity dysfunctions. Other mechanical factors have been suggested, such as structural abnormalities of the follicle or local inflammation (2). Management of this alopecia is difficult and its course is typically chronic and relapsing. The treatment aim is to stop inflammation and further irreversible destruction of hair follicles. Antibiotics remain the first-line therapy, due both to their anti-inflammatory and antimicrobial properties (1). Although topical fusidic acid is widely used as adjuvant treatment, there are few data regarding its oral use. We report a case of folliculitis decalvans successfully treated with oral fusidic acid. Our patient was a 41-year old Cape Verdean woman with a two month history of alopecia with painful, purulent discharge at the vertex of the scalp. The patient was diagnosed with human immunodeficiency virus type 1 (HIV-1) infection 5 years prior and was stable on her regimen of efavirenz, tenofovir, and emtricitabine, with undetectable viral load. She denied application of topical or capillary products. Dermatological examination revealed a patch of cicatricial alopecia with crusts and follicular pustules (Figure 1). Direct microscopic examination and mycological culture showed no fungal element. A diagnosis of folliculitis decalvans was established and the patient was started on oral fusidic acid at a dose of 500 mg three times a day. Betamethasone dipropionate 0.05% and salicylic acid 3% lotion as well as azelaic acid 5% lotion were also applied to the affected area once daily. After two months of treatment, the patient showed clinical improvement, with less erythema and suppuration of the affected scalp. A partial hair regrowth was noted, mainly at the periphery. Subsequently the patient maintained only topical therapy, and no recurrences were observed after 6-months of follow-up. Fusidic acid is useful in the treatment of skin and soft tissue infections, particularly those due to S. aureus, as shown by randomized controlled studies (3). The clinical efficacy of fusidic acid in the treatment of folliculitis decalvans has been reported previously. Bogg was the first to describe this useful effect (4). Sutter also reported good results with fusidic acid used both topically and orally (500 mg three times a day) (5). However, both failed to report the treatment duration or the outcome on discontinuation. Abeck described three patients that responded to a three week oral course of fusidic acid (500 mg three times a day) and to a maintenance treatment with zinc sulfate (4). During the following year, recurrence was observed in only one patient after ending zinc sulfate therapy. Oral antibiotics are frequently used to treat folliculitis decalvans. Tetracyclines and the combination of clindamycin with rifampicin are the most commonly used (2). However, the disease usually progresses when treatment is stopped. Fusidic acid is an anti-staphylococcal drug with few adverse effects. It is highly bioavailable orally, and has a long plasma half-life. Despite years of clinical use in numerous countries, resistance rates remain at low levels to date (6). Since clinical series or cases including ours have shown good results, this drug should not be forgotten when considering treatment options for folliculitis decalvans." }, { "id": "pubmed23n1089_1711", "title": "Kerion celsi due to <i>Microsporum audouinii</i>: a severe form in an immunocompetent girl.", "score": 0.009708737864077669, "content": "A 9-year-old girl presented a large inflammatory cup-shaped scalp lesion with alopecia surrounded by pustules, dander, and suppuration associated with an occipital inflammatory lymphadenopathy for 1 month.

Anthropophilic dermatophytes (i.e. Trichophyton tonsurans and Trichophyton violaceum) have been generally associated with high rates of asymptomatic carriage. The aim of this study was to compare the efficacy of the hairbrush, toothbrush and cotton swab methods for diagnosing scalp carriage as well as to determine the prevalence and related dermatophyte species for both asymptomatic and symptomatic tinea capitis in Adana Province, Turkey. A screening study was carried out between February 2006 and May 2006, covering three schools and a total of 1560 children with 857 (54.9%) boys and 703 (45.1%) girls, aged between 7 and 17 years (10.6 +/- 2.3 years). The diagnosis was made by using three of the methods mentioned above with inoculation onto Sabouraud glucose agar. Symptomatic tinea capitis was not detected in the study; however, 21 (1.3%) asymptomatic carriers, with 9 (42.9%) boys and 12 (57.1%) girls, aged 7 to 13 years (9.7 +/- 1.9 years) were detected. The diagnosis was made via hairbrush in 13, via cotton swab in 4 and via toothbrush in 4. The mean age (P = 0.075) and gender differences were found to be statistically insignificant (P = 0.26). The most common isolated species was Trichophyton mentagrophytes var. mentagrophytes (90.4%) followed by Trichophyton audouinii (4.8%) and Microsporum gypseum (4.8%). Nine children had Arab origin (P = 0.005), and 12 had immigrated from the south-eastern region of Anatolia, Turkey. The screening of 32 households of 21 children with asymptomatic carriage enabled the researchers to detect the carrier state in three mothers and one sister, resulting in a total of four households (12.5%), with T. mentagrophytes var. mentagrophytes isolated, by hairbrush method in three cases and cotton swab in one case. If the methods were to be used alone, the prevalence of asymptomatic carriage would be found as 1.0% (16 of 1592) in the hairbrush, 0.3% (4 of 1592) in the toothbrush and 0.3% (5 of 1592) in the cotton swab methods; whereas the combined use of these three methods could reveal a total prevalence of 1.6% (25 of 1592). The hairbrush method was significantly found to be more effective in detecting dermatophyte fungi than the toothbrush (P &lt; 0.01) and the cotton swab methods (P &lt; 0.05). There was also a statistically significant difference between the use of a single method and the combination of all other three methods (P &lt; 0.005). In summary, it was found that the prevalence of asymptomatic carriage did not cover symptomatic tinea capitis prevalence (1.6% vs. 0%), and the dominant species was zoophilic T. mentagrophytes (92%, 23 of 25). Asymptomatic carriage was not found to be related to age, gender and the coexistence of other dermatophytoses; however, race (Arab origin) was found to be the only risk factor. For laboratory diagnosis, no method was found to be nominated as a gold standard; hence, a combined use of diagnosing methods was suggested." }, { "id": "pubmed23n0662_21111", "title": "Inflammatory tinea capitis: non-healing plaque on the occiput of a 4-year-old child.", "score": 0.009433962264150943, "content": "Inflammatory tinea capitis is an uncommon condition in Singapore.

Case 1 was a 10-year-old boy visiting us because of pain and swelling in his right scrotum continuing for the past ten days. His right scrotum was found to contain a hen-egg sized tender mass. The testis and epididymis could not be differentiated by palpation. The blood count disclosed 10,000 white blood cells. At operation, two appendix epididymis were found in his right scrotum. One of them was twisted 360 degrees clockwise and 10 x 8 x 5 mm in size. Case 2 was a 11-year-old boy with complaint of pain in his left lower abdomen and left scrotum for the past three days. Palpation of his left scrotal contents revealed a slightly hard testis and tender epididymis. At operation, we found his left spermatic cord to be twisted 90 degrees counterclockwise and appendix epididymis 180 degrees counterclockwise. The twisted appendix epididymis was 10 x 8 x 7 mm in size. Case 3 was a 13-year-old boy whose complaint was left scrotal pain. The upper pole of his left testis was found to be swollen and tender by palpation. The exposure of his left scrotum at operation revealed that his left epididymis was abnormally attached to his left testis and had two appendices. One of these appendix epididymis was twisted 180 degrees clockwise and measured 10 x 10 x 8 mm. Case 4 was a 19-year-old male who suffered from right testicular pain for the past seven days. He had a history of three intermittent episodes of similar right testicular pain during the past two years. His right testis was enlarged and palpated slightly hard and tender. We explored his right scrotum surgically and found the appendix testis twisted and enlarged to little-finger's head size. However, it was impossible to determine whether the rotation was clockwise or counterclockwise because the twisted appendix was too severely damaged. The preoperative diagnosis was correct in one case and three were erroneously diagnosed as having torsion of spermatic cord. All four cases were treated by surgery which relieved all patients of discomfort." }, { "id": "pubmed23n0482_23041", "title": "[Screening Examination and Management of Dermatophytosis by Trichophyton tonsurans in the Judo Club of a University].", "score": 0.009259259259259259, "content": "Thirty-one members of the Judo Club of a certain university (age: 18~23) underwent a screening examination for dermatophytosis by Trichophyton tonsurans.

KD's past medical history was notable for atopic dermatitis, and a positive family history of autoimmune thyroid disease. Upon examination he had well circumscribed areas of hair loss throughout his scalp, with exclamation mark hairs seen on dermoscopy. Eyebrows and eyelashes were intact, no epidermal changes of scale or erythema were noted on the scalp and no palpable lymph nodes were present. He was diagnosed with alopecia areata at this time and was treated with Clobetasol 0.05% solution QHS as well as Kenalog 2.5 mg/ml injections to the areas of hair loss. Patient followed up two months later with worsening of his alopecia at a rapid pace, presenting now with hair loss of the entire scalp and loss of the eyebrows. He was diagnosed with progression to alopecia universalis at that time, with a corresponding SALT (Severity of Alopecia Tool) score of 100. Both KD and his mother stated the hair loss was causing much distress in the patient's life both at school and at home. After a thorough discussion of treatment alternatives to include continued topical high dose steroids, intralesional injections, high dose oral methylprednisolone, topical irritation with anthralin, topical immunotherapy with diphenylcyclopropenone (DPCP) or squaric acid dibutylester (SADBE) and systemic immunosuppressives, both the mother, patient and clinician agreed to try tofacitinib 5 mg twice daily with continued usage of topical steroids. Patient and his family was counseled about support groups, and local meetings to ease the mental distress associated with this condition. After baseline labs were obtained and reported within normal limits, to include CBC, CMP, thyroid studies, lipids and Quanitferon gold, KD was started on tofacitinib 5 mg BID. Labs were repeated one month later, and 3 months ongoing thereafter. At KD's 3 month follow up, after starting tofacitinib 5 mg twice daily, KD showed complete regrowth of the eyebrows with minimal hair growth of the posterior occiput (Figure 1 a-d). At KD's 6 month follow up he had 100% regrowth of eyebrows and complete scalp regrowth, resulting in a SALT score of 0 (Figure 2). KD reported no side effects until month 6, after full hair regrowth, when patient started to report mild headaches. Drug holiday was offered but the patients family chose to discontinue treatment at this time as they were concerned side effects were secondary to medication usage. Unfortunately, patient was lost to follow-up after the discontinuation of treatment. From previous case reports we can postulate that his alopecia returned to baseline after discontinuation of tofacitinib. KD had an incredible response to treatment, as has been reported previously in literature of adolescents using these novel therapies. This is the youngest patient ever reported to be successfully treated with oral tofacitinib 5 mg twice daily for alopecia and its variants.

Treatment of alopecia areata is challenging. There is very little information on the use of surgical therapies for the treatment of alopecia areata in the medical published work. A 24-year-old male patient was referred to a private hair transplantation clinic owned by one of the authors for the treatment of therapy-resistant alopecia areata affecting both eyebrows. He had quickly lost all body hair 4 years prior beginning from the scalp. He received psoralen and ultraviolet A (PUVA) therapy for alopecia universalis and all body hair re-grew except his eyebrows. Alopecia areata was stable for the 18 months following the last medical treatment he received. Because there was no response to various medical therapeutic agents, we decided to transplant occipital hairs to the eyebrow area. After the patient understood and accepted all risks, occipital hairs were transplanted to the eyebrows by using the follicular unit extraction technique. Postoperatively, the patient did not receive any topical or systemic therapies for alopecia areata. Although 40% hair re-growth was detected in his eyebrows at 1 year postoperation, this rate was 80% by 2 years postoperation. However, there was resistance to re-growth in the medial eyebrow regions. New eyebrows grew as occipital hairs and required trimming. His satisfaction from the surgical procedure was 90% at the end of the 24th postoperative month.

Follow-up observations of five very old patients are reported in whom diagnosis was made too late, resulting in blindness of both eyes. Five patients (age 76-84 years, 4 women, one man) with GCA became blind in both eyes because diagnosis had been delayed (two patients) or onset of therapy was too late (three patients). In two patients who also had arterial hypertension, the symptom \"headache\" had been misleading. Symptoms of accompanying general diseases masked the real diagnosis, particularly in the second patient who had renal insufficiency, coronary artery disease, and unilateral obstruction of the internal carotid artery. Symptoms that failed to lead to the correct diagnosis were: muscle or chewing pain (three patients), circumscribed numbness around the mouth (second patient), and persistent headache despite normalization of blood pressure. Normal findings from cranial CTAs (two patients) led to the wrong reassurance of the patient. Swelling of the optic disk (two patients) was misdiagnosed by ophthalmologists, as was a retinal branch arterial occlusion (first patient). Three patients, afraid of possible side effects caused by glucocorticoids, took ineffective alternative medications. Poor vigilance led to blindness of the fifth patient with long-standing polymyalgia rheumatica. Targeted examinations at the onset of symptoms are necessary.

In the early morning of May 2, his families found him unresponsive and snoring; he was brought into the ER of our hospital. He had histories of hypertension, gout, and hyperlipidemia since 42 years of the age. On admission, his blood pressure was 120/70, heart rate 102 and regular, and body temperature 36.3 degrees C. His respiration was regular and he was not cyanotic. Low pitch rhonchi was heard in his right lower lung field. Otherwise general physical examination was unremarkable. Neurologic examination revealed that he was somnolent and he was only able to respond to simple questions such as opening eyes and grasping the examiner's hand, but he was unable to respond verbally. The optic discs were flat; the right pupil was slightly larger than the left, but both reacted to light. He showed ptosis on the left side, conjugate deviation of eyes to the left, and right facial paresis. The oculocephalic response and the corneal reflex were present. His right extremities were paralyzed and did not respond to pain Deep tendon reflexes were exaggerated on the right side and the plantar response was extensor on the right. No meningeal signs were present.

Post mortem examination revealed occlusion of the circumflex branch of the left coronary artery due to atherom plaque rupture and myocardial infarction involving the posterior and the lateral wall with a rupture in the postero-lateral wall. Marked atheromatous changes were seen in the left internal carotid, the middle cerebral and the basilar arteries; the left internal carotid and the middle cerebral arteries were almost occluded by thrombi and blood coagulate. The territories of the left middle cerebral and the occipital arteries were infarcted; but the left thalamic area was spared. The neuropathologist concluded that the infarction was thrombotic origin not an embolic one as the atherosclerotic changes were severe. Cardiac rupture appeared to be the cause of terminal sudden hypotension and cardiopulmonary arrest. It appears likely that a vegetation which had been attached to the aortic valve induced thromboembolic occlusion of the left internal carotid artery which had already been markedly sclerotic by atherosclerosis. It is also possible that the vegetations in the aortic valve came from mural thrombi at the site of acute myocardial infarction, as no bacteria were found in those vegetations." }, { "id": "pubmed23n1076_12839", "title": "Childhood-Onset Leber Hereditary Optic Neuropathy: Particular Features.", "score": 0.009345794392523364, "content": "Leber hereditary optic neuropathy (LHON) is an optic neuropathy of mitochondrial inheritance.

With syncope, about 20-30% of the cases remain unexplained after a complete evaluation, but, unlike in seizures, a psychogenic etiology is not usually investigated. We prospectively evaluated patients referred to our epilepsy center for evaluation of recurrent syncope-like episodes, that is, limp, motionless fainting. All patients had a negative syncope workup. We performed EEG-video monitoring with activation by suggestion (\"induction\"), similar to what is used for diagnosis of psychogenic seizures. Activation was performed with patients standing or sitting up. The diagnosis of psychogenic pseudosyncope required: (1) an activation procedure that triggered the habitual event; (2) a clinical event of loss of postural tone and limp, motionless unresponsiveness with eyes closed; (3) normal EEG before, during, and after the clinical event, that is, no epileptiform abnormalities, a normal alpha rhythm during unresponsiveness, and no suppression of background or slowing as is typically seen in syncope. Ten patients were recruited over an 18-month period. Habitual syncope-like episodes were triggered in 9 of 10 (90%) patients, and all 9 were shown to have psychogenic pseudosyncope (eyes closed, motionless, unresponsive with normal EEG including normal alpha rhythm). In one patient, no episode was triggered, so a diagnosis could not be made. Among the 9 patients for whom episodes were recorded, age ranged from 21 to 60 (mean=36). Five were women. Duration of symptoms ranged from 6 months to 15 years (mean=4.2 years). Event frequency ranged from four per day to two per month. Prior evaluations for syncope included ECG in all patients, two-dimensional echocardiogram in three, Holter monitoring in two, and tilt-table test in five.

Insulin therapy rapidly brought glycaemia down to its normal level and the clonsism disappeared. Five months later, the patient had no other seizure and the EEG was normal. Epileptic seizures are frequent in hyperglycaemia without ketosis (25% of the cases) where they are mainly partial and motor (75 to 86% of the cases), rarely associated with a focal lesion (15% of the cases with CT scan). They are rare in patients with ketoacidosis. This apparent protective effect of ketoacidosis may be attributed to an increase of GABA bioavailability consecutive to acidosis. CPE is resistant to antiepileptic treatments. In CPE induced by hyperglycaemia without ketosis normalization of blood glucose level with insulin therapy is concomitant with a rapid cure of epilepsy. Thus glycaemia should be measured in all patients presenting with CPE, the aim being to diagnose hyperglycaemia without ketosis rapidly to avoid hyperosmolality and to prescribe an adequate treatment based exclusively on insulin and rehydration." }, { "id": "pubmed23n0408_11448", "title": "[Acute repetitive giratory seizures as a manifestation of nonketotic hyperglycemia].", "score": 0.009009009009009009, "content": "This 71 years old women without any history of epilepsy had diabetes mellitus.

All these data, in addition to the analytical data, are describing an immunodeficiency that by the family-maternal history, seems to be X-linked, as several males have died of a similar clinical condition (the father of the patient contributed the Y chromosome, the mother the X). Among the X-linked immunodeficiencies is Wiskott-Aldrich syndrome, an entity described with an initial triad of symptoms consisting of bleeding (typical BUT absent in the case: heavy bleeding after circumcision, bloody diarrhea), recurrent infections and eczema. In addition to thrombocytopenia, they are at increased risk for autoimmune phenomena and lymphoid neoplasms.

2-year-old boy. His personal history includes 3 episodes of acute otitis media, 1 meningococcal meningitis and 2 pneumonias (one middle lobe and one left upper lobe). She has been admitted on 3 occasions for thrombopenic purpura (on three occasions antiplatelet antibodies were negative and bone marrow showed normal megakaryocytes). Several males of the maternal family had died in childhood due to infectious processes. Physical examination showed lesions typical of atopic dermatitis. The immunological study showed a slight decrease in T-lymphocyte subpopulations; elevated IgA and IgE; decreased IgM and IgG at the lower limit of normal. What is the most likely diagnosis?

Several bone and joint abnormalities can occur in patients with PID, with arthritis being the most common. Joint manifestations, of which arthritis is the most common, occur chiefly in humoral PIDs (agammaglobulinemia, common variable immunodeficiency, hyper-IgM syndromes, and IgA deficiency) and occasionally in other PIDs (chronic granulomatous disease and Wiskott-Aldrich syndrome). Monoarthritis or oligoarthritis is the usual pattern, although polyarthritis may occur, occasionally with nodules suggesting rheumatoid arthritis. Arthritis in patients with PID is usually infectious in nature, the most common causative organism being Mycoplasma, followed by Staphylococcus, Streptococcus, and Haemophilus. These bacteria can induce not only synovial infections, but also aseptic arthritogenic inflammatory responses. Arthritis having no demonstrable relation to chronic infection has been reported also and ascribed to dysimmunity-driven mechanisms that exhibit a number of specific features. Bone lesions are far less common and usually due to infections complicating humoral PID.

The syndrome was first described in 1959, and in more detail in 1962, by Luft and et al., who reported a picture of hypermetabolism with high temperature, extreme sweating, tachycardia, dyspnoea at rest, polydipsia, polyphagia and irritability but normal thyroid function. In 1971 and 1976 Haydar and Di Mauro presented a second case and proposed treatment with chloramphenicol. Our patient has the third case of the syndrome reported so far: her case was initially published in 1987. CASE REPORT. Since her 17th year of life the patient had suffered from episodes of fever, tachycardia and sweating. At the age of 32 these attacks worsened, leading to unconsciousness and apnoea. The patient then had to be intubated, ventilated and sometimes resuscitated. The diagnosis of MH susceptibility and Luft's disease was made on biochemical grounds after the first muscle biopsy in 1983. Therapy with chloramphenicol failed. Therapy with beta blockers, vitamin C and K or E, coenzyme Q10 and a high-caloric diet was started in 1985. The patient was registered with an emergency service, which flew her to our ICU whenever she had a severe crisis. For milder episodes she was supplied with an oxygen breathing mask at home. Myalgia increased with the episodes starting in 1988, and the patient needed dantrolene infusions and analgesics at home. To facilitate venepuncture a Port-A-Cath system was implanted in 1987, which had to be removed four times due to infection and sepsis. A muscle biopsy was taken in Rotterdam, which revealed differences in mitochondrial function from the biochemical findings recorded in 1983 and not in keeping with Luft's disease. Unfortunately, the patient was not able to undergo further metabolic investigations or therapeutic trials. ANAESTHESIA. The patient received three local and six general anaesthetics in our clinic. The muscle biopsies, two in 1983 and one in 1985, were performed under local infiltration with procaine and were uneventful. The general anaesthetics were carried out without MH trigger substances following pretreatment with dantrolene for the following surgical procedures: the repair of an extensive arterio-venous fistula between the brachiocephalicus trunk and the right jugular and subclavian vein, revision of the sternum cerclage, implantations and explanations of infectious Port-A-Cath systems. We used etomidate, propofol and fentanyl or alfentanil with nitrous oxide and oxygen for induction and maintenance of anaesthesia. Muscle relaxation was induced with vecuronium or atracurium. All cardiovascular, respiratory, metabolic and temperature measurements stayed in normal ranges. After the extensive vascular repair (av fistula) the patient had to be mechanically ventilated for some hours until normal body temperature was restored. At the end of all other periods of anaesthesia she was extubated in the operating theatre. In five cases the postoperative period was uneventful. Only once she developed a crisis with hyperthermia, tachycardia, sweating and dyspnoea. INTENSIVE CARE. From 1985 to 1992 the patient was treated in our ICU 21 times. On 11 occasions she was already intubated and being ventilated by the emergency service on arrival. Extubation was usually possible within 2-20 h. During the crisis, heart rate was about 160-190 per minute and temperature above 40 degrees C. Serum values of CK, glucose, BUN, electrolytes, lactate and thyroid hormones were always in the normal ranges. Blood gas controls showed a constant respiratory alkalosis, arterial pCO2 values decreasing to 20 mm Hg or less. In addition to mechanical ventilation, treatment consisted in dantrolene infusions and droperidol injections, supplemented from 1989 onward with piritramide injections because of the increased severity of myalgia.

Initially, hypercalcemic crisis is best treated by forced intravenous fluid administration with normal saline (and furosemide) in combination with high doses of prednisone. Fluid-, sodium- and potassium balances ought to be checked during this type of treatment.

The rarity and limited knowledge of the disease make its management challenging. Prompt diagnosis of the condition is extremely important to decrease both long- and short-term complications. Treatment options depend on hemodynamic stability and the location of the dissection- with more distal lesions treated more conservatively as opposed to proximal lesions which are treated with percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). The following are the two cases with different presentation, management and outcomes. Our first patient was a 35-year-old woman with no medical history who presented with acute, anginal pain, diaphoresis and palpitations. She was hemodynamically stable on presentation, with work-up significant for electrocardiogram (ECG) with sinus bradycardia, ST elevation in leads V1-V6, and elevated troponin level of 4 ng/ml. There was no evidence of a pulmonary embolism on computed tomography (CT) of the chest. A coronary angiogram showed 100% dissection of the proximal to mid-left anterior descending (LAD) artery. Attempts to place a stent in the proximal to mid LAD were unsuccessful as the true lumen of the LAD was not accessible. The patient became hemodynamically unstable, and an emergent CABG was done, restoring blood flow. The patient recovered during her hospital stay and was discharged with dual antiplatelet therapy (DAPT), beta-blockers, and atorvastatin. The second patient was a 28-year-old woman, with a history of hypertension who presented with anginal chest pain. Workup showed ECG with minimal ST elevations in anteroseptal leads, with elevated troponin level to 0.71 ng/ml. Coronary angiogram showed 40-50% stenosis of the mid LAD with an aneurysmal segment. An echocardiogram showed no evidence of wall motion abnormalities, and she had a normal left ventricular ejection fraction (LVEF). She was discharged home the next day, on medical management. After two days, she returned to the hospital with similar complaints, with work-up significant for ECG with non-specific ST-T abnormality, and troponin level which peaked at 2.22 ng/ml. She was started on a heparin drip, and a repeat left heart catheterization revealed type 2 dissection of the mid to distal LAD, with intravascular ultrasound showing a fractional flow reserve of 0.76. She was discharged home on DAPT, beta-blocker, calcium channel blocker (CCB), and atorvastatin, with close cardiology follow up.

Early post-operative hypoparathyroidism was defined at day 5, by serum calcium less than 8 mg/dl. and serum phosphate less than 4 mg/dl or by serum calcium only if greater than 7.5 mg/dl. Patients afflicted with early hypoparathyroidism were given calcium tablets without any vit D for 1 year at most. Follow-up, checking serum Ca, P and i PIH was done on a 3 months basis during 1 year. Permanent hypoparathyroidism was defined by persistence of the above-mentioned criteria after 1 year, and eventually vit D was started. 27 patients (5.6% our of 477 bilateral thyroid resections) experienced early post-op hypoparathyroidism. Inciting factors were previous thyroid surgery (4), radioiodine treatment (2), modified neck dissection (2), sternal split with mediastinal node clearance (1), visualization of 1 parathyroid gland only (3 redo cases) and autotransplantation of more than 1 parathyroid (1 case). 1 patient was lost for follow-up. 25 others recovered a normal parathyroid function. 1 is permanently hypoparathyroid (1 redo case with other risk factors).

She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

A Swan-Ganz catheter, placed for intraoperative monitoring, was kept in place and she was hydrated with 125 mL/hour of normal saline, achieving a PAWP of 10 to 16 mm Hg. Her mean arterial blood pressure without pharmacologic intervention was 95 to 110 mm Hg. She had continued clinical improvement with resolution of her left hemiparesis.

A continuous retrospective study was conducted from 2004 to 2009. It included patients with a non-united fracture or osteotomy at 6 months or more post-surgery, with less than 10mm inter-fragment gap. Daily 20-min ultrasound sessions were continued until bone healing was achieved or for a maximum 6-month duration. Radio-clinical control was performed at months 3 and 6; treatment compliance and transmitter positioning were checked at each follow-up visit. Sixty non-unions were included in the series. One patient was excluded for early material breakage. Mean fracture-to-surgery interval was 271 days. The 6-month consolidation rate was 88%. There was no loss to follow-up. Mean ultrasound treatment duration was 151 days (range, 90-240 days). Bone healing correlated significantly with stability of the internal fixation assembly (P=0.01). The seven cases of failure included four fixations,considered unstable at inclusion, one femoral non-union associated with BMI 45 and one inadequate subchondral roughening (at the time of arthrodesis). There was a significant difference in delay to non-union treatment start between the groups with (251 days) and without (420 days) bone healing. The present results are in line with the literature. The main prognostic factors were fracture fixation stability, short time to treatment, and inter-fragment gap less than 10mm. Bone healing rates in the literature are around 80% for non-union treated at around 6 months, versus 60% for more than 12 months' delay. Factors such as gender, bone site, smoking, numbers of previous operations or type of osteosynthesis do not impact consolidation. External treatment offers an alternative to traditional surgery (graft, or bone-marrow concentrate or bone morphogenetic protein injection), provided that the fracture fixation is stable. Bone healing rates are better, and the procedure is non-invasive. External treatment results using ultrasound are similar to those using electromagnetic fields; the main difference lies in treatment session duration, which is 20 min for ultrasound, versus 3 hours for electromagnetic fields. Active patient commitment is vital, as the treatment is delivered at home, although the machine is equipped with a monitor to count treatment cycles. The 88% bone healing rate supports advocating first-line implementation in non-union of less than 10mm with stable osteosynthesis. This rate is higher than in traditional surgery, with a unit cost at least 60% lower: €1772 for external therapy, versus €4480 for decortication with or without fracture fixation exchange (itemized 08c50 under the French healthcare treatment coding system).

No new lesions were identified on follow-up by clinical breast examination alone.

A category assessment of BI-RADS 0 refers to an incomplete evaluation with further imaging required including additional mammographic views including spot compression or magnification and or ultrasound. BI-RADS 1 refers to a negative examination, meaning that there are no masses, suspicious calcifications or areas of architectural distortion. There can be no description of a finding in the report if it is categorized as a BI-RADS 1.  BI-RADS 2 is consistent with benign findings. Benign findings include secretory calcifications, simple cysts, fat-containing lesions, calcified fibroadenomas, implants and intramammary lymph nodes. BI-RADS 3 is probably benign and should have shortened interval follow-up to determine stability. The risk of malignancy is below 2%. There are very strict classifications to qualify a finding in the BI-RADS 3 category: a non-palpable, circumscribed mass on a baseline mammogram; a focal asymmetry, which becomes less dense on spot compression images, or a solitary group of punctate calcifications. Any findings other than this cannot be placed in the category 3. BI-RADS 4 is a suspicious abnormality, which can represent the chance of being malignant (in percent). The BI-RADS category 4 is subdivided into a, b, and c. The subcategory of (a) has a low probability of malignancy with a 2% to 10% chance of malignancy. The subcategory of (b) has an intermediate change of malignancy ranging from 10% to 50%. The subcategory of (c) has a high probability of malignancy ranging from 50% to 95%. BI-RADS 5 is highly suggestive of malignancy more than 95%. If something is placed in this classification and the pathology comes back as benign, the recommendation is still surgical consultation, because the pathology is discordant with the radiographic findings.

Exclusion or confirmation of the presence of cancer with minimum intervention and delay. When an abnormality is detected on screening mammography, clinical evaluation and thorough radiologic work-up are needed to determine its significance. Clinical evaluation should include a history and a thorough examination of the breast, axilla and supraclavicular areas. In the radiologic work-up, diagnostic mammograms should be obtained with additional views, spot compression and magnification views as appropriate. Current mammograms should be compared with previous mammograms whenever possible. The mammographic report should include a precise description of the abnormal features visualized and an estimate of the level of suspicion of cancer they imply. Whenever there is any doubt in the interpretation of mammograms, the interpretation of 2 experienced readers should be obtained.

Category 2 abnormalities may be followed up by periodic mammographic and clinical examinations. Follow-up examination of category 2 abnormalities should be carried out at approximately 6 and 12 months.

The rationale of follow-up should be explained, and women should be made aware that it is not possible to provide complete assurance that an abnormality is benign. Category 3 abnormalities usually require image-guided fine-needle or core biopsy. Every image-guided needle biopsy should be accompanied by a full report. Category 4 abnormalities should usually be excised. This may be preceded by image-guided needle biopsy. When surgical biopsy is carried out, the margins of the resected specimen must be free of tumour.

Mammographically occult cancers can be detected by sonography in 10 to 40 % of the cases depending on the patient's breast density and age. The mean size of cancers detected only by ultrasound is not significantly different to that only detected by mammography. The prevalence of breast cancers detected by ultrasound is approximately equal to the one detected by mammography, regarding the total number of examined patients. Breast ultrasound should be the preferred imaging procedure in the case of a palpable lump, leading to a definitive diagnosis itself or with an additional consecutive core needle biopsy. For women without symptoms, breast sonography should be mandatory and complementary to mammography in the case of breast density grade II (BI-RADS) or more. Application of breast ultrasound as a primary method or an alternative to mammography has not yet been evaluated sufficiently.

Also in the group of ADH (n = 3) pathology revealed one DCIS (lesion not visible on mammography but depicted as a suspicious mass on US). In the group of LCIS (n = 3) pathologists found an invasive lobular carcinoma (ILC). Among the benign papillary lesions (n = 57) histopathologic analysis of the surgical specimen revealed 7 malignant lesions (4 papillary carcinomas and 3 DCIS), whose mammographic and ultrasound findings were indistinguishable from benign lesions. Altogether there were 10 false negative results (underestimation) out of 74 core biopsies with a diagnosis of high-risk proliferative breast lesions.

It is possible to assume that, when there is a low imaging suspicion for malignancy, when enough tissue has been sampled for pathology and no atypia is found within the lesions, surgery is not mandatory but a very careful follow-up is recommended.

She lives with her husband and enjoys gardening and reading. She has two grown children and three grandchildren who live approximately 180 miles away. SECOND CANCER DIAGNOSIS  One morning while showering, Sarah detected a painless quarter-sized lump on her inner thigh. While she thought it was unusual, she felt it would probably go away. One month later, she felt the lump again; she thought that it had grown, so she scheduled a visit with her primary care physician. A CT scan revealed a 6.2-cm soft-tissue mass in the left groin. She was referred to an oncologic surgeon and underwent an excision of the groin mass. Pathology revealed a grade 3 malignant melanoma. She was later tested and found to have BRAF-negative status. Following her recovery from surgery, Sarah was further evaluated with an MRI scan of the brain, which was negative, and a PET scan, which revealed two nodules in the left lung. As Sarah had attended a cancer support group during her breast cancer treatment in the past, she decided to go back to the group when she learned of her melanoma diagnosis. While the treatment options for her lung lesions included interleukin-2, ipilimumab (Yervoy), temozolomide, dacarbazine, a clinical trial, or radiosurgery, Sarah's oncologist felt that ipilimumab or radiosurgery would be the best course of action. She shared with her support group that she was ambivalent about this decision, as she had experienced profound fatigue and nausea with chemotherapy during her past treatment for breast cancer. She eventually opted to undergo stereotactic radiosurgery. DISEASE RECURRENCE  After the radiosurgery, Sarah was followed every 2 months. She complained of shortness of breath about 2 weeks prior to each follow-up visit. Each time her chest x-ray was normal, and she eventually believed that her breathlessness was anxiety-related. Unfortunately, Sarah's 1-year follow-up exam revealed a 2 cm × 3 cm mass in her left lung, for which she had a surgical wedge resection. Her complaints of shortness of breath increased following the surgery and occurred most often with anxiety, heat, and gardening activities, especially when she needed to bend over. Sarah also complained of a burning \"pins and needles\" sensation at the surgical chest wall site that was bothersome and would wake her up at night. Sarah met with the nurse practitioner in the symptom management clinic to discuss her concerns. Upon physical examination, observable signs of breathlessness were lacking, and oxygen saturation remained stable at 94%, but Sarah rated her breathlessness as 7 on the 0 to 10 Borg scale. The nurse practitioner prescribed duloxetine to help manage the surgical site neuropathic pain and to assist with anxiety, which in turn could possibly improve Sarah's breathlessness. Several nonpharmacologic modalities for breathlessness were also recommended: using a fan directed toward her face, working in the garden in the early morning when the weather is cooler, gardening in containers that are at eye level to avoid the need to bend down, and performing relaxation exercises with pursed lip breathing to relieve anxiety-provoked breathlessness. One month later, Sarah reported relief of her anxiety; she stated that the fan directed toward her face helped most when she started to feel \"air hungry.\" She rated her breathlessness at 4/10 on the Borg scale. SECOND RECURRENCE: MULTIPLE PULMONARY NODULES  Sarah's chest x-rays remained clear for 6 months, but she developed a chronic cough shortly before the 9-month exam. An x-ray revealed several bilateral lung lesions and growth in the area of the previously resected lung nodule. Systemic therapy was recommended, and she underwent two cycles of ipilimumab. Sarah's cough and breathlessness worsened, she developed colitis, and she decided to stop therapy after the third cycle. In addition, her coughing spells triggered bronchospasms that resulted in severe anxiety, panic attacks, and air hunger. She rated her breathlessness at 10/10 on the Borg scale during these episodes. She found communication difficult due to the cough and began to isolate herself. She continued to attend the support group weekly but had difficulty participating in conversation due to her cough. Sarah was seen in the symptom management clinic every 2 weeks or more often as needed. No acute distress was present at the beginning of each visit, but when Sarah began to talk about her symptoms and fear of dying, her shortness of breath and anxiety increased. The symptom management nurse practitioner treated the suspected underlying cause of the breathlessness and prescribed oral lorazepam (0.5 to 1 mg every 6 hours) for anxiety and codeine cough syrup for the cough. Opioids were initiated for chest wall pain and to control the breathlessness. Controlled-release oxycodone was started at 10 mg every 12 hours with a breakthrough pain (BTP) dose of 5 mg every 2 hours as needed for breathlessness or pain. Sarah noted improvement in her symptoms and reported a Borg scale rating of 5/10. Oxygen therapy was attempted, but subjective improvement in Sarah's breathlessness was lacking. END OF LIFE  Sarah's disease progressed to the liver, and she began experiencing more notable signs of breathlessness: nasal flaring, tachycardia, and restlessness. Opioid doses were titrated over the course of 3 months to oxycodone (40 mg every 12 hours) with a BTP dose of 10 to 15 mg every 2 hours as needed, but her breathlessness caused significant distress, which she rated 8/10. The oxycodone was rotated to IV morphine continuous infusion with patient-controlled analgesia (PCA) that was delivered through her implantable port. This combination allowed Sarah to depress the PCA as needed and achieve immediate control of her dyspneic episodes. Oral lorazepam was also continued as needed. Sarah's daughter moved home to take care of her mother, and hospice became involved for end-of-life care. As Sarah became less responsive, nurses maintained doses of morphine for control of pain and breathlessness and used a respiratory distress observation scale to assess for breathlessness since Sarah could no longer self-report. A bolus PCA dose of morphine was administered by Sarah's daughter if her mother appeared to be in distress. Sarah died peacefully in her home without signs of distress.

Purpose To assess outcomes from 6-, 12-, and 24-month follow-up of probably benign findings first identified at recall from screening mammography in the National Mammography Database (NMD). Materials and Methods This retrospective study included women recalled from screening mammography with BI-RADS category 3 assessment at additional evaluation from January 2009 through March 2018 from 471 NMD facilities. Only the first BI-RADS category 3 occurrence for women aged 25 years or older with no personal history of breast cancer was analyzed, with biopsy or 2-year imaging follow-up. Cancer yield and positive predictive value of biopsies performed (PPV3) were determined at each follow-up. Results Among 45 202 women (median age, 55 years; range, 25-90 years) with a BI-RADS category 3 lesion, 1574 (3.5%) underwent biopsy at the time of lesion detection, yielding 72 cancers (cancer yield, 4.6%; 72 of 1574 women). For the remaining 43 628 women who accepted surveillance, 922 were seen within 90 days (with 78 lesions biopsied and 12 [15%] classified as malignant). The women still in surveillance (31 465 of 43 381 women [72.5%]) underwent follow-up mammography at 6 months. Of 3001 (9.5%) lesions biopsied, 456 (15.2%) were malignant (cancer yield, 1.5%; 456 of 31 465 women; 95% confidence interval [CI]: 1.3%, 1.6%). Among 18 748 of 25 997 women (72.1%) in surveillance who underwent follow-up at 12 months, 1219 (6.5%) underwent biopsy with 230 (18.9%) malignant lesions found (cancer yield, 1.2%; 230 of 18 748 women; 95% CI: 1.1%, 1.4%). Through 2-year follow-up, the biopsy rate was 11.2% (4894 of 43 628 women) with a cancer yield of 1.86% (810 malignancies found among 43 628 women; 95% CI: 1.73%, 1.98%) and a PPV3 of 16.6% (810 malignancies found among 4894 women). Conclusion In the National Mammography Database, Breast Imaging Reporting and Data System (BI-RADS) category 3 use is appropriate, with 1.86% cumulative cancer yield through 2-year follow-up. Of 810 malignancies, 468 (57.8%) were diagnosed at or before 6 months, validating necessity of short-interval follow-up of mammographic BI-RADS category 3 findings. © RSNA, 2020 <iOnline supplemental material is available for this article.</i See also the editorial by Moy in this issue." }, { "id": "pubmed23n0580_20005", "title": "Talk to your patients about breast disease.", "score": 0.008928571428571428, "content": "You have been caring for a 32-year-old woman for the past several years.

Additionally, 66 cancers were discovered between two consecutive screenings after one, two, or three negative screening examinations (interval cancers). The study group consisted of 25,920 women who have been participating since 1975 in a breast cancer screening program in Nijmegen, the Netherlands. In this program, single view mammography (lateromedial projection) was administered as the sole screening examination every two years. Physical examination was not part of the screening program. All previous histologic and radiologic material from 64 of those \"interval\" patients was available and was reviewed. In 19 of the 64 patients, direct or indirect signs of tumor were seen on the previous screening mammogram on review (observers error). In four cases the site of the tumor lay outside the imaging field (technical error). In 41 cases, no signs of tumor could be seen on the mammograms even on review. By calculated tumor doubling times, 20 of these 41 cases were probably too small to be detected at the last screening (\"real\" interval cancers). However, 21 cases were probably large enough but were somehow masked from radiologic detection. The mean reasons for this \"masking\" proved to be: 1) dense breast, 2) poorly outlined tumor mass of diffuse infiltrative type, mainly invasive lobular carcinomas, and 3) intraductal localization. The authors suggest that women with dense breasts be screened more frequently, using more views and modalities and with broader criteria for advising surgical biopsy.

Several methods for a breast biopsy now exist. The most appropriate method of biopsy for a patient depends upon a variety of factors, including the size, location, appearance and characteristics of the abnormality. The different types of breast biopsies include fine needle aspiration (FNA), vacuum assisted biopsy, core needle biopsy, and surgical excision biopsy. Breast biopsies can be done under ultrasound, MRI or a stereotactic biopsy technique. Vacuum assisted biopsies are typically done using stereotactic techniques when the suspicious lesion can only be seen on mammography. On average, 5-10 biopsies of a suspicious breast lesion will lead to the diagnosis of one case of breast cancer." }, { "id": "pubmed23n0254_403", "title": "Stereotactic breast biopsy.", "score": 0.008849557522123894, "content": "The substantial majority of questionable lesions detected by mammography are benign, and there is growing interest among health care professionals and patients in alternatives to surgical biopsy for diagnosing these lesions. Stereotactic breast biopsy is an x-ray guided method for localizing and sampling breast lesions discovered on mammography and considered to be suspicious for malignancy. Its use in sampling small, nonpalpable breast lesions has been investigated over the past 15 years, using fine-needle aspiration for cytology and, more recently, core-needle biopsy for histology. Multiple series comparing stereotactic biopsy with surgical biopsy have shown that stereotactic techniques accurately sample small lesions and have a sensitivity of 90 to 95 percent for breast cancer detection. State-of-the-art stereotactic breast biopsy is comparable in sensitivity to surgical biopsy, and the procedure is quicker, cheaper, and easier than the standard practice of preoperative, mammographically guided localization followed by surgical biopsy. In an age of miniaturization, stereotactic techniques provide miniature breast biopsies. The University of Chicago acquired the first prone stereotactic table in the United States in 1986, and we have found stereotactic breast biopsy to be a very good alternative for certain lesions that would otherwise require surgical biopsy for diagnosis. Most lesions (70 percent) sent to conventional biopsy at the University of Chicago between 1986 and 1989 were graded by observers as being in a low-suspicion category (less than 10 percent chance of malignancy based on mammographic findings), and the positive malignancy yield of this category of lesions was seven percent. These lesions were also examined with stereotactic fine-needle aspiration performed as a \"piggy-back\" procedure to the needle localization for surgery. The results of this study have led us to use stereotactic biopsy rather than surgical biopsy for low-suspicion lesions since then. We currently use stereotactic breast biopsy for about half the nonpalpable lesions considered for breast biopsy at our institution and find it to be reliable and readily accepted by informed patients. The introduction of automated core-biopsy guns has escalated interest in the technique, due to increased confidence in the histologic samples obtained and the ability to make specific benign diagnoses more frequently. Some centers have extended the potential use of stereotaxis to virtually all suspicious mammographic lesions, including those with a high probability of malignancy, to plan definitive surgery. Based on current estimates, there are now over 1,000 centers either investigating or using stereotactic biopsy for occult breast lesions." } ] } } }

We report a two-step-surgery approach to preserve the bone stock using autologous cancellous bone in a bacterial infected non-union for subsequently leg length reconstruction. The 24-year-old male patient from Belarus was admitted to our department with persistent wound secretion and subsequent osteomyelitis of the right femur 3 years after initial surgery, several revisions, and several different antibiotic therapies.

Finally, an AO fixator external was applied for 10 weeks combined with appropriate antibiotic treatment followed by 5 weeks antibiotic-free window. The bone defect was stabilized by a long gamma trochanteric nail after removal of the AO fixateurexterne. A wide resection of the fragments was performed and the resected bone tissue was crushed and placed adjacent to the nail. Noteworthy, the biopsies of both re-section sides revealed same germs as detected in initial biopsies. Thus, antibiotics were administered for additional 3 months. Frequent radiographic and clinical controls showed a remodeling of the femur during a period of 3 years and no signs of infection.

Another is a 15-year-old boy with open grade IIIb fracture tibia and fibula (mid-distal third junction) of right leg, wound debridement and ankle spanning triangular external fixation was applied on same day and after two months, external fixation was removed due to florid infection and plaster of Paris was applied. Instead of the tedious and demanding treatment options like Ilizarov, a new technique described by Masquelet is used here. It uses bone cement as a spacer to fill the cavity to form pseudo-membrane around it and in the second stage autologous cancellous bone graft fills the gap of even more than 5 cm, to achieve union. The membrane also secretes vascular and osteo-inductive factors to stimulate bone regeneration and also prevents resorption of the bone graft and achieves early fracture healing avoiding tedious options like bone transport in external fixator. By this two staged technique, union occurred clinically and radiologically in these two cases." }, { "id": "pubmed23n0039_12145", "title": "[Infected tibial shaft pseudarthroses, treatment and results (author's transl)].", "score": 0.009900990099009901, "content": "In a follow up study of 47 patients with infected pseudarthrosis of tibia therapy and results are declared.

Treatment usually involves internal fixation using a volar Henry approach with placement of a volar locking plate. Optimal treatment becomes less apparent when significant bone loss occurs. No case of an open distal radius fracture treated using a staged Masquelet technique involving proximal tibial autograft is available in the literature. Herein, we describe and discuss a case report of a novel technique to treat a large (5 cm) bone defect for an open distal radius fracture. A 59-year-old man suffered an open, comminuted, and intra-articular distal radius fracture with 5 cm of bone loss. He was treated using a staged Masquelet technique with incorporation of ipsilateral proximal tibial autograft with a bone harvester to obtain cancellous autograft and bone marrow graft. The patient initially underwent emergent I and D, acute carpal tunnel release, and internal and external fixation. A 5 cm bone void was filled with antibiotic cement. Four weeks later, the antibiotic cement was removed, cancellous bone graft and marrow were harvested from the proximal tibia, and the graft was placed within the prior bone void. Fracture site healing was confirmed radiographically and with computer-tomography imaging 3 months later. The patient has demonstrated excellent results 1 year post-operative with 60° of wrist flexion, 40° of wrist extension with mild pain, and full finger range of motion with radiographic union. Internal fixation with placement of a volar locking plate remains the mainstay of treatment for distal radial fractures. However, in more comminuted fractures with bone loss, treatment becomes more challenging. We have presented a unique case utilizing a staged Masquelet technique with incorporation of a proximal tibial autograft to educate readers on an alternative option and technique for autograft donor sites in these more complicated fractures." }, { "id": "pubmed23n0260_528", "title": "[Surgical treatment of diaphyseal tibial fractures.

Gastrocnemius muscle and soleus muscle flaps are generally used as rotational flaps for the tibia. The distal third of the tibia can often not be covered with the gastrocnemius muscle and soleus muscle flaps. Treatment distal to the distal third of the tibia is difficult because fewer flap options are available. In the present report, we describe our experience with a Gustilo Type 3B open tibial fracture treated by gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure. The participant was a 17-year-old male who injured his left tibia in a motorcycle traffic accident. Physical examination revealed a wound of 13 cm × 7 cm extending from the medial lower leg to the posterior aspect, with extensive skin loss. There was no nerve or vascular injury. The tibia was exposed, with detachment of the periosteum. The radiograph revealed a tibial shaft fracture. The AO/OTA classification was 42-A3.3, and it was classified as a Gustilo-Anderson Type 3B fracture. Gastrocnemius muscle and soleus muscle flaps were lifted in the area of the soft-tissue defect and then, placed over the tibia. Despite this, the distal portion of the tibia remained uncovered. Therefore, a flexor hallucis longus flap was lifted and placed over the distal portion of the tibia. On day 7 after the injury, the external fixation device was removed and the tibial shaft was fixated with two Ender nails (4.5 mm in diameter). The clinical course was satisfactory, and the skin graft and flap were successful. Bone union was achieved without infection, and the resulting range of motion was normal. For the treatment of Gustilo-Anderson Type 3B open tibial fractures, early treatment of the soft-tissue defect is vital. We surgically treated a Gustilo-Anderson Type 3B open tibial fracture with gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure. In the event of a soft-tissue defect in the distal third of the tibia, the use of a proximally based flexor hallucis longus flap is an effective surgical approach." }, { "id": "pubmed23n1009_12107", "title": "Prevention of infection in open fractures: Where are the pendulums now?", "score": 0.009708737864077669, "content": "Soft tissue management and fracture fixation including initial external fixation in Gustilo-Anderson type II and type III open fractures are cornerstones in the treatment but details on timing and type of wound closure, irrigation and debridement, systemic and local antibiotics, antimicrobial-coated implants and the use of Bone Morphogenetic Protein-2 remain controversial. This article looks at current clinical evidence of these items for the management of open fractures. Timing of debridement and wound closure remains critical. Early debridement by an experienced team within 24 h seems adequate while gross contamination, a devascularized limb, a multi-injured patient and compartment syndrome require immediate surgical intervention. Wound closure during the first surgery was shown to result in reduced rates for infections and nonunion. If soft-tissue reconstruction is needed, it should be performed within the first 7 days. Regarding types of irrigation fluid, antiseptic and antibacterial solutions did not prove to be superior to saline. High pressure irrigation has not been demonstrated to be beneficial whereas antibiotic administration as soon as possible has been proven to be favorable. Administration of more than 72 h was not superior to shorter systemic antibiotic intervals. For Gustilo-Anderson type I and II, broad spectrum antibiotic therapy is reasonable. Additional aminoglycosides for broader coverage are recommended in Gustilo-Anderson type III fractures. There is newer literature on the beneficial effects of the use of local antibiotics, e.g. by antibiotic beads. Coating of internal fixation devices is a modern approach to improve infection prophylaxis and gentamicin-coated implants have been demonstrated to be safe in clinical application. Vacuum assisted closure (VAC) could not evidence negative pressure wound therapy to reduce infection risk, improve self-rated disability or quality of life in open fractures, however, enhance treatment costs. Recombinant human bone morphogenetic proteins (rhBMP)-2 showed promising data in Gustilo-Anderson type III open tibial shaft fractures with lower rates of invasive secondary procedures. In conclusion, there is evidence for thorough debridement and irrigation with saline, early soft tissue coverage and the use of systemic and local antibiotics.

We report a nine-year-old Caucasian girl who had hereditary motor and sensory neuropathy type I and who was admitted with a grade I open tibia fracture after a fall from a small height. Plain radiographs showed a dislocated tibia and fibula fracture. An open reduction with internal fixation with a compression plate osteosynthesis was performed, and soft tissue debridement combined with an external fixateur was undertaken. Three months later, she was re-admitted with localized swelling and signs of a local soft tissue infection in the middle of her tibia. Plain radiographs showed a non-union of the tibia fracture, and microbiological analysis confirmed a wound infection with cefuroxime-sensitive Staphylococcus aureus. Because of the non-union, the osteosynthesis was replaced with an Ilizarov external fixateur, and appropriate antibiotic therapy was initiated. Four months after the initial accident, the fracture was consolidated and we removed the external fixateur. If there is a pre-existing neuropathy and if disease makes it difficult for a child to follow all post-operative instructions, salvage procedures should be kept in mind in case of complications. There are multiple therapeutic options, including osteosynthesis, intramedullary nailing systems, cast therapy, or an external fixateur like the Ilizarov or Taylor spatial frame system.

Titanium elastic nails have become a popular technique for fixation of pediatric tibial shaft fractures. They act as internal splints that impart relative stability to the fracture, promoting callus formation at the fracture site<sup2</sup. After the patient is placed in the supine position, the proximal tibial physis is marked using fluoroscopy. An anteromedial and anterolateral incision are made distal to the physis. Entry holes are created in the proximal part of the tibia, and appropriately sized titanium nails are introduced into the bone. Nail size should be 40% of the width of the canal, yielding 80% canal fill when 2 nails are used. The nails are prebent into a gentle C-shape to increase cortical contact at the apex so that 3-point fixation is achieved. The nails are passed to the fracture site, and the fracture is then reduced. The nails are then passed across the fracture site and stopped proximal to the distal tibial physis. The nails are then cut and tamped distally until there is just a short portion of nail left out of the proximal part of the tibia so that the nails can be removed once the fracture is healed. The wounds are then closed, and postoperative immobilization is applied. Many pediatric tibial shaft fractures can be treated with closed reduction and cast immobilization. Open fractures, or fractures that fail nonoperative management, can be treated with external fixation, open reduction and internal fixation (ORIF), or intramedullary stabilization<sup3</sup. Anatomic reduction and fracture compression can be achieved with ORIF; however, a drawback to this technique is the lack of soft-tissue coverage in the diaphyseal area of the tibia, which can lead to infection and wound-healing problems<sup4</sup. External fixation has traditionally been the technique of choice for open tibial fractures; however, with the ability to use flexible tibial nails in both open and closed tibial fractures, external fixation is now reserved for open fractures with large soft-tissue defects or in fractures with segmental bone loss.

Thirty-six patients (37 bone lesions) with infectious bone defects were treated with induced membrane technique between January 2011 and June 2014. There were 28 males and 8 females with an average age of 36 years (range, 20-68 years). All bone defects were post-traumatic infectious bone defect. The bone defect was located at the tibia and fibula in 24 cases (25 bone lesions), at femurs in 6 cases (6 bone lesions), at ulnas and radii in 2 cases (2 bone lesions), at calcanei in 3 cases (3 bone lesions), and at clavicle in 1 case (1 bone lesion). The average time between onset and the treatment of induced membrane technique was 6.2 months (range, 0.5-36.0 months); 15 patients were acute infections (disease duration was less than 3 months). At the first stage, after the removal of internal fixator (applicable for the patients who had internal fixation), complete debridement of infection necrotic bone tissue and surrounding soft tissue was performed and the bone defects were filled with antibiotic-impregnated cement spacers. If the bone was unstable after debridement, external fixator or plaster could be used for stabilization. Patients received sensitive antibiotics postoperatively. At the second stage (usually 6-8 weeks later), the cement spacer were removed, with preservation of the induced membrane formed by the spacer, and filled the bone defect with autologous iliac bone graft within the membrane. The hospitalization time after debridement was 17-30 days (mean, 22.2 days), and the hospitalization time after the second stage was 7-14 days (mean, 10 days). All the flaps healed uneventfully in 16 cases treated with local flap transposition or free flap grafting after debridement. One patient of femur fracture received Ilizarov treatment after recurrence of infection at 11 months after operation; 1 patient of distal femoral fracture received amputation after recurrence of infection at 1 month after operation; 1 patient of distal end of tibia and fibula fractures received ankle arthrodesis after repeated debridements due to the recurrence of infection; 1 patient of tibia and fibula fractures lost to follow-up. The other 32 patients (33 bone lesions) were followed up 1-5 years (mean, 2 years) without infection recurrence, and the infection control rate was 91.7% (33/36). All the patients had bony union, and the healing time was 4-12 months (mean, 7.5 months); no refracture occurred. One patient of femur bone defect had a lateral angulation of 15° and leg discrepancy of 1.5 cm. Superficial pin infection was observed in 7 cases and healed after intensive wound care and oral antibiotics. Adjacent joint function restriction were observed in 6 cases at last follow-up.

They are frequently associated with loss of limb, infection and high levels of morbidity. All the authors considered, now, that there are five keys to successful treatment: antibiotic therapy, radical debridement and pulsed lavage irrigation, stabilization of fracture with minimal further devascularization, early soft tissue coverage and early bone-grafting. It rests, also, a number of controversies in the management of open tibial fractures, not least of which is the method of fracture stabilization: the choice between intramedullary nailing and external skeletal fixation, the use of reamed or unreamed nails. Fifty-seven patients with 62 open fractures of the tibial shaft type IIIA, B and C (Gustilo) were treated between 1.01.1994 and 31.12.1998 in the Department of Orthopaedic Surgery of the Emergency Hospital, Iasi, Romania. There were 29 cases type IIIA fractures, 26 cases type IIIB and 7 cases type IIIC (Mess score showed the viability of the limb). Our patients were 36 males and 21 females; their mean age was 36 years (range 17 to 70). Forty-six patients were injured in road traffic accidents and 11 in other traumatic incidents. In 33 cases the skeletal stabilization was achieved by Ender nailing under general or regional anesthesia. In 15 cases we used a bilateral uniplanar external fixator (Burghele) and 14 fractures were stabilized with an Ilizarov external fixator. We note a secondary amputation after the failure of the revascularization of the limb in a type IIIC fracture. All fractures united; the mean time to union was 30.2 weeks--in the external fixation group and 26.4 weeks--in the Ender nailing group. Malunions occurred slightly more frequently in the external fixation group that in the Ender nailing group (15.7% versus 5.8%). We noted--also--more secondary procedures required in the external fixation group. The infection rate was 3 of 33 (9.1%) in the Ender nailing group compared to 4 deep (13.8%) and 8 pin-tract infection (27.6%) in the external fixation group. Our study suggests that Ender nailing has several advantages over external fixation in the management of severe open tibial shafts fractures.

Human cases of loxoscelism have been observed in diverse countries of different continents in temperate and tropical regions. In Chile loxoscelism is caused by Loxosceles laeta, spider with domestic habits. Loxoscelism can be observed into two well definited clinical variants: cutaneous loxoscelism (CL) and systemic or viscerocutaneous loxoscelism (VCL) which occur in around 83.3 and 16.7% cases respectively. Within the universe of CL patients a clinical modality in which necrotic lesion is not present or is insignificant, but presenting a remarkable edema, particularly when the bite is on the face, which has received the name of CL with an edematous predominance (CLEP). In this paper the individual description and the assambled analysis of 10 cases, four males and six females, age ranging from 6 to 68 years, of CLEP are presented. Nine cases occurred in warm periods spring through fall and one in winter. In six cases the accident causing spider was seen and two of these were identified as L. laeta adult females. In all cases the patients went or were transported to emergency medical services 4-24 h after the bite. The predominant initial symptom was a burning stinging sensation at the site of the bite, followed by intensive pain which expanded the neighbour areas concomitantly with the emerging and progressive edema. In four of the nine patients in who the bite was on the face, the edema involved all of it, closed both eyelids and expanded to the neck and upper part of the thorax. In three cases the enormous edema was the only significant clinical manifestation, whereas in the remaining seven conjunctly with the edema, a small violaceous plaque or a blister of serous content gave place to a little livedoid plaque (diameter 0.3-0.8 cm) which evolved to desquamation without leaving any scarring. The edema was characterized by its brilliant rose color, painful and hard which is not accompanied by regional adenopathy. Treatment of the 10 patients depended on the moment in they were seen by us.

Cutaneous adverse reactions are usually maculopapular exanthemas, although hypersensitivity syndrome, acute generalized exanthematous pustulosis, and Stevens-Johnson syndrome have also been reported (1). We report the case of a patient with a maculopapular rash triggered by clindamycin who developed cutaneous lesions on striae distensae (SD). A 47-year-old woman was referred to our clinic for pruritic cutaneous lesions which had started 6 days earlier. Her past clinical history included hypertension, hypothyroidism, hyperuricemia, cholecystectomy, caesarean section, and endometriosis-related abdominal surgery, and she was taking levothyroxine, allopurinol, imidapril, and omeprazole. The skin rash first developed on her neck and back on the 3rd day of clindamycin oral treatment (300 mg every 6 hours), which was prescribed as antibiotic prophylaxis for a tooth implant. General malaise (but not fever) was also reported. Physical examination revealed an erythematous maculopapular eruption symmetrically distributed on the neck, abdomen, and back (Figure 1, A), with isolated lesions involving the proximal upper and lower limbs (Figure 1, B). There was a striking vertical distribution of skin lesions along the SD on the lateral sides of the abdomen (Figure 1, C). No mucosal involvement was found, and laboratory studies showed no abnormalities. Clindamycin withdrawal was followed by prescription of a course of oral deflazacort, starting at 30 mg daily and tapering down during a 9-day period. On the 5th day of treatment, the rash had almost cleared with minimal desquamation (Figure 1, D). Eight weeks after clearance of the skin rash, informed consent was obtained in order to perform an allergological evaluation of clindamycin, including prick and intradermal (ID) tests on the forearm and patch tests on the upper back (2). For patch testing, powder of the commercial capsules (Dalacin®) was diluted in petrolatum (pet.) and water (aq.), resulting in a final 1% clindamycin dilution. Parenteral clindamycin preparations were used in therapeutic concentrations for prick tests (150 mg/mL) and dilutions in saline of 1/100 and 1/10 for the ID test. Other authors have reported that these concentrations do not seem to irritate the skin (3-6). Prick and ID tests were assessed after 20 min and 24 hours, respectively. Patch tests were removed after the 2nd day, and late reactions were evaluated on day 2 and day 4. Prick and ID test results after 20 min were negative. Late results of ID tests with clindamycin (1.5 and 15 mg/mL) were positive: erythematous infiltrated papules about 7×7 mm and 18×15 mm were observed at 24 hours and lasted until the 8th day. Patch tests with clindamycin 1% in pet. and 1% in aq. were also positive (+ on day 2 and day 4). Positive late skin tests suggested delayed-type non-IgE-mediated allergic clindamycin hypersensitivity. Oral challenge tests are considered to be the gold standard to establish or exclude drug hypersensitivity. Due to the positive result of late skin test to clindamycin, oral challenge was not performed in our patient (3,5). The Koebner isomorphic phenomenon has been described in cutaneous reactions induced by drugs, such as antibiotics and chemotherapy. Chronic pressure on the skin is probably involved in the onset of skin lesions in hand-foot eruptions induced by tyrosine kinase inhibitors (sorafenib and sutinib). Solar exposure and cutaneous trauma also seem to play a role in the location of papulopustular eruptions caused by endothelial growth factor receptor inhibitors (erlotinib) (7). More frequent involvement in traumatized skin and surgical scars has been reported in the context of linear IgA bullous dermatosis and leukocytoclastic vasculitis triggered by vancomycin and cefuroxime (8). SD are produced by non-penetrating physical trauma, similar to friction or pressure. Different dermatoses can develop along SD skin lesions (like plaque psoriasis, pustular psoriasis, lichen planus, vitiligo, discoid lupus erythematosus, lupus vasculitis, urticarial vasculitis, or chronic graft-versus-host disease) (9). Bevacizumab, etretinate, and corticosteroid-induced ulcers, hyperpigmentation caused by bleomycin, and urticariform lesions triggered by diclofenac are examples of different type of drug-induced abnormalities involving SD (10). In summary, we identified clindamycin as the cause of the cutaneous reactions that occurred in our patient on the basis of the results of the skin tests and clinical history. Our findings confirmed a delayed-type hypersensitivity reaction, possibly involving a T-cell-mediated immunologic mechanism. Intradermal and patch tests were found to be useful in order to confirm the diagnosis (4,5). We did not find reports in the literature of drug-induced cutaneous eruptions along the SD as a manifestation of a Koebner phenomenon. Clinical underreporting of this phenomenon could explain the scarce literature on this cutaneous adverse reaction." }, { "id": "pubmed23n0755_3767", "title": "[Lip synechiae after erythema multiforme].", "score": 0.009433962264150943, "content": "Mucosal erosions in bullous diseases and leading to mucosal sequelae are widely described in toxic epidermal necrolysis (TEN).

It later spread to the right side of the trunk and to the right arm. When she was 9 years old, she developed similar lesions on her left arm and leg. After she was 13 years old, no new skin lesions appeared. There was no family history of similar lesions. On examination, there were numerous linear and whorled, reddish-brown, hyperkeratotic plaques, with central atrophy and raised borders, following Blaschko's lines on all of the extremities. These lesions on the extremities extended to the dorsum of the hands and feet (Fig. 1). She had hyperkeratotic lesions on the pressure points of both of the soles, but no palm involvement. The number of lesions on the right side was greater than that on the left. Reddish-brown annular plaques with central atrophy and raised borders, appearing in zosteriform configuration, and numerous individual 2-3-mm erythematous lichenoid papules were observed on the right side of the thorax and the right inguinal region (Fig. 2). No face, scalp, or mucous membrane involvement was seen. The nails of the second and fifth fingers of the right hand and the nail of the third finger of the left hand showed nail dystrophy with longitudinal ridges and pterygium. All the nails of the right foot and the nails of the first and fifth toes of the left foot showed dystrophic changes with subungual keratosis. The patient was otherwise in good health. Two biopsy specimens taken from a hyperkeratotic plaque and a lichenoid papule showed an epidermal invagination with angulated parakeratotic tier, denoting cornoid lamella. The epidermis just underneath the cornoid lamella displayed vacuolization and the granular layer was absent. The adjacent epidermis was atrophic, and hydropic degeneration within the basal cell layer was seen. In the dermis, a nonspecific, mild, chronic, inflammatory cell infiltrate, telangiectatic vessels, and pigment-laden macrophages were present. These findings were consistent with linear porokeratosis (Fig. 3). Microscopic examinations and mycologic cultures of the nails were negative. We decided to treat our case systemically with retinoids, but the patient refused this therapy. So, topical tretinoin 0.05% was started once a day.

The lumbar nodule regressed spontaneously before treatment. The clinical diagnosis was mycosis fungoides. We obtained three skin biopsies, one from a patch lesion and the others from a nodule; the third was sent to a reference hospital to determine the rearrangement. Histologic examination was similar in the three biopsies and revealed an atypical lymphoid infiltrate in the superficial dermis with epidermotropism and a tumoral nodule of atypical, small-sized lymphocytes in the deep dermis and subcutaneous level (Fig. 2). The atypical infiltrate was CD3+, CD4+, CD8-, T-cell intracellular antigen (TIA)+/-, Epstein-Barr-encoded RNA (EBER)-, and CD56-. The biopsy of one left axillary adenopathy was compatible with mycosis fungoides (Fig. 3).

However, atypical BP with polymorphic clinical presentations is rarely encountered, leading to misdiagnosis and delayed treatments (1). BP with lesions resembling erythema gyratum repens or figurate erythema has been regarded as a paraneoplastic phenomenon (1). Herein we report a case with erythema annulare centrifugum-like presentation of BP without evidence of underlying malignancy. A 64-year-old woman first presented with multiple large, tense bullae on the trunk and four extremities. She was diagnosed with BP according to the typical clinical, histopathological, and direct immunofluorescence findings. There were no annular lesions at that time. After a treatment course of systemic corticosteroids and azathioprine, the cutaneous symptoms were controlled. One year after discontinuing her medications, a pruritic bullous eruption reappeared with several annular erythematous plaques (Figure 1, a). The patient reported no mucosal involvement and took no new medications before the onset of skin lesions. On physical examination, multiple circular and arcuate erythematous lesions with slightly raised borders were seen on the trunk and both legs. Some erosions and tiny vesicles were noted on the erythematous edges. There were no other systemic symptoms or abnormalities. Laboratory studies, including complete blood count, liver and renal function tests, electrolytes, antinuclear antibody, complement levels, anti-Ro and anti-La antibodies, urine routine, stool routine, and chest X-ray, were normal. The biopsy specimen obtained from the rim of the annular lesions revealed slight vacuolar change at the dermoepidermal junction and perivascular and interstitial lymphocytic infiltration with numerous eosinophils in the upper dermis (Figure 1, b). Direct immunofluorescence showed linear deposits of immunoglobulin G (IgG) and C3 along the basement membrane (Figure 1, c). Histopathological features and immunofluorescence examinations were consistent with BP. There was no evidence of hematological or solid malignancy from further imaging and laboratory testing. The patient was started on oral prednisolone 30 mg/day and azathioprine 150 mg/day, with significant improvement over the following month. Complete regression of all skin lesions was achieved two months later, so the prednisolone dose was gradually tapered and then ceased. Under maintenance monotherapy of azathioprine 100 mg/day, there were no signs of BP recurrence or malignant disease during the one-year follow-up period. The annular erythema variant of BP is extremely rare. Therefore, in this case, erythema multiforme, subacute cutaneous lupus erythematosus, erythema annulare centrifugum, and urticarial vasculitis should be considered in the clinical differential diagnoses. Pathological features and immunofluorescence results can clearly rule out these possibilities. Until now, only 13 cases of BP presenting as annular erythema had been documented in the English literature, described as figurate erythema-like, erythema gyratum repens-like, or erythema annulare centrifugum-like manifestations (1-3). An association with internal malignancy in patients with these types of lesions had been reported (1). Nevertheless, as in most previous case reports (3), malignant diseases were not found in our patient. The precise mechanism of the annular erythema form of BP is unknown. Some authors considered it a variant of pre-bullous phase lesions, usually presenting as itchy erythematous patches or urticarial plaques (4). Based on this case, however, this assumption is less likely because the annular, erythema annulare centrifugum-like skin lesions appeared one year after the initial onset of bullous eruption, and simultaneously with the exacerbation of the bullous phase of BP. The exact pathogenesis of annular BP may be similar to that in erythema annulare centrifugum. Further investigations are warranted to clarify this issue. It should be noted that an erythema annulare centrifugum-like or figurate erythema-like manifestation in the absence of underlying malignancy can occasionally be a feature of BP. Making the correct diagnosis may be difficult if there is no concurrent bullous presentation. Clinicians should be vigilant for the development of this type of BP. The histological and direct immunofluorescence findings and the detection of circulating autoantibodies by indirect immunofluorescence or enzyme-linked immunosorbent assay remain crucial tools for establishing a definitive diagnosis." }, { "id": "article-135196_26", "title": "Toxic Epidermal Necrolysis -- Differential Diagnosis", "score": 0.008849557522123894, "content": "Stevens-Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN) are in the same disease spectrum.

In the initial examination, it is important that the patient be disrobed as completely as possible to minimize chances of missing important individual skin lesions and permit accurate assessment of the distribution of the eruption.

In evaluating a patient with DI, the major challenge is to differentiate between primary polydipsia and neurogenic and nephrogenic DI. This is best accomplished through a series of steps that start with simple clinical observation, and progress, as necessary, to more complicated diagnostic procedures (Fig. 1). If the diagnosis is not clear from the clinical setting and the patient's history, the first step is to measure plasma osmolality and sodium under conditions of ad libitum fluid intake. If the results are clearly above the upper limit of normal range, primary polydipsia is excluded and the work-up can proceed directly to administration of vasopressin or DDAVP and/or a measurement of plasma vasopressin levels to differentiate between neurogenic and nephrogenic DI. If basal plasma osmolality and sodium fall within normal range, the standard dehydration test should be performed. If urine osmolality does not increase above that of plasma despite evident dehydration, primary polydipsia is excluded and the effect of vasopressin or DDAVP on urine osmolality should be examined to differentiate between neurogenic and nephrogenic DI. If administration of antidiuretic hormone increases urine osmolality by more than 50 per cent, the patient has severe neurogenic DI. If the increase in urine osmolality is less than 50 per cent, the patient has nephrogenic DI. In patients who do not concentrate urine above that of plasma in response to dehydration, the best approach is to measure plasma vasopressin, osmolality, and sodium after the latter have been increased above normal range by dehydration and/or infusion of hypertonic saline. When these results are plotted on a suitable nomogram (Fig. 2), neurogenic DI can be clearly diagnosed from the relative deficiency of vasopressin. In patients with normal vasopressin levels, primary polydipsia can be differentiated from nephrogenic DI by examining the relationship of urine osmolality to plasma vasopressin (Fig. 3), obtained during dehydration and/or graded vasopressin infusion. In evaluating a patient with sustained hypernatremia, it is only necessary to assess thirst, which can be done by a simple bedside observation. In a patient without obvious neurologic or cognitive impairment, absence of thirst in the face of plasma osmolality above 305 mosm/kg (plasma sodium above 150 mEq/L) is diagnostic for hypodipsic hypernatremia.

Nevertheless, there was also a component of psychogenic polydipsia because the daily basal fluid intake was superior to 15 liters, and in view of the fact that the urinary osmolality could reach 600 mOsm/kg, the endocrine defect cannot totally be responsible for the enormous volume of fluid intake. This is the first case in the world literature in which the association between potomania and deficiency in the secretion of ADH is reported. Since ADH is one of the factors which regulate the behaviour of various animal species it is possible that its deficiency may be directly responsible for the psychic disorder which led to the potomania.

The diagnostic value of the measurement of urinary vasopressin with a rather insensitive commercially available vasopressin kit was compared with plasma vasopressin measurement by a highly sensitive radioimmunoassay (RIA). Thirteen normal subjects and 27 patients with polyuria/polydipsia were examined by an 8-h fluid deprivation test. In all blood samples (0800 h, 1200 h, 1400 h and 1600 h) and in all urine collections (2-hourly fractions), osmolality as well as vasopressin were measured. Using plasma vasopressin measurement with a highly sensitive RIA as gold standard test, nine patients were classified as having primary polydipsia, whereas 18 had partial or complete cranial diabetes insipidus. Whereas the substitution of plasma vasopressin measurement by urinary vasopressin measurement alone did not provide 100% separation between both groups, the product of urinary vasopressin and urinary osmolality related to plasma osmolality completely separated the patients with primary polydipsia from those with diabetes insipidus. Urinary measurement of vasopressin and osmolality alone, which was recommended as a noninvasive diagnostic procedure in children, was too insensitive for exact differential diagnosis in our adult patients. The simultaneous measurement of plasma vasopressin and plasma osmolality in a dehydration test is the most powerful diagnostic tool in the differential diagnosis of polyuria/polydipsia.

It is mostly due to a defect in arginin-vasopressin (AVP) synthesis (central DI); other causes are: AVP resistance (nephrogenic DI), abnormal thirst regulation (primary polydipsia) or early destruction of AVP by placental enzymes (gestational DI). A thorough medical history is warranted to investigate nocturnal persistence of polyuria (night waking being a good sign of its organic nature) to specify the onset and duration of the trouble, the medication use and the potential hereditary nature of the disorder. The next step is based on weight and blood pressure measurements and especially the quantification of beverages and diuresis over a 24-hour cycle. Assessment of signs of dehydration, bladder distention, pituitary hormone hyper- or hyposecretion, tumor chiasmatic syndrome, granulomatosis and cancer is required. The diagnosis is based on biological assessment, pituitary magnetic resonance imaging (MRI) and results of a desmopressin test. In severe forms of DI, urine osmolality remains below 250 mOsmol/kg and serum sodium greater than 145 mmol/L. In partial forms of DI (urine osmolality between 250 and 750), the water deprivation test demonstrating the incapacity to obtain a maximal urine concentration is valuable, together with vasopressin or copeptin measurement. The pituitary MRI is done to investigate the lack of spontaneous hyperintensity signal in the posterior pituitary, which marks the absence of AVP and supports the diagnosis of central DI rather than primary polydipsia (although not absolute); it can also recognize lesions of the pituitary gland or pituitary stalk. Acquired central DI of sudden onset should suggest a craniopharyngioma or germinoma if it occurs before the age of 30 years, and metastasis after the age of 50 years. Fifteen to 20% of head trauma lead to hypopituitarism, including DI in 2% of cases. Transient or permanent DI is present in 8-9% of endoscopic transphenoidal surgeries.

She subsequently developed fulminant hepatitis secondary to Hepatitis E viral infection, spontaneously aborted at 24 weeks of gestation and later died.Case 2 was also a 31-year-old Ghanaian woman who was admitted with a four-day history of jaundice. She had low grade fever, but no history of abdominal pain, haematuria, pale stool or pruritus. She next developed fulminant hepatitis secondary to Hepatitis E viral infection. However, she did not miscarry but died at 28 weeks of gestation.Case 3 was a 17-year-old Ghanaian woman who was referred to the tertiary health facility on account of jaundice and anaemia. She had delivered a live male infant at maturity of 32 weeks but noticed she was jaundiced and had a presentation of active disease 3 days prior to delivery. The baby was icteric at birth and on evaluation, had elevated bilirubin (mixed type) with normal liver enzymes. Hepatitis E virus infection was confirmed in both mother and baby. However, the jaundice and the hepatomegaly resolved in mother and baby after 5 and 12 days respectively. To the best of our knowledge, these are the first documented cases of fatal fulminant hepatic failures resulting from HEV infection in Ghana." }, { "id": "pubmed23n0396_3498", "title": "[Dynamics of serum copper level in patients in the acute phase of hepatitis B and in early convalescence].", "score": 0.009900990099009901, "content": "Analysis of serum copper (Cu) level dynamics during the acute phase of hepatitis acute B and the early convalescence in compliance with gravity of the acute disease course.

In all examined patients, the serum Cu level was determined according to the following scheme: at the first, tenth, twentieth and the last day of the hospitalisation and additionally one time at four weeks after discharging from the clinic. The serum Cu level was made by atomic absorption spectrometry (AAS) at the wave length of 324.8 nm. The received data were subjected to statistical analysis according to t-Student's test and in cases of significant differences according to the variants of c-Cochran and Cox's tests. According to the SI Unit Conversion Guide, the values 11.22 to 23.58 mumol/l were taken as the normal range. The values derived from the control group of 24 healthy persons (13 men and 11 women) aged 22 to 69 years.

Her vaginal bleeding had ceased, however her platelet continued decreasing to 12,000/µl during first several days of hospitalization despite receiving platelet transfusion. On the tenth hospital day, she suddenly complained of severe headache and blurred vision. She had bilateral edema and erythema of palpebral, chemosis, decreased in visual acuity, and reduced ocular motility. Ear and nose examination were normal. Peripheral blood smear showed no blast. Prothrombine time (PT), INR, APTT tests were normal and D Dimer was slightly increased (3.3 mg/l; NV ≤0.5 mg/l).

These findings are similar to those with alcoholic liver disease. However, in the NASH-situation alcohol doesn't play an important role. Risk factors for the development of NASH are obesity and diabetes. Most of the patients are clinically asymptomatic. This means, that a diagnosis of NASH is a diagnosis of exclusion: Viral induced, autoimmune, metabolic and toxic liver disease have to be excluded. The disease has a benign clinical course. The risk of cirrhosis is low. So far, there is no established treatment. Preliminary reports suggest a positive effect of weight-loss and ursodeoxycholic acid. Wilson's disease, a copper storage disorder, in which biliary copper excretion is reduced, is inherited as an autosomal recessive trait. Most patients with Wilson disease become symptomatic between the ages of 6 and 15. In about 90% of patients serum ceruloplasmin levels and serum copper concentrations are reduced. Copper excreation is increased. Histologic examination of liver biopsy specimens reveals fatty infiltration, Mallory bodies and ballooned glycogen nuclei, abnormalities which are also found in alcoholic liver disease. The definitive diagnostic parameter is the quantitative determination of liver copper content (&gt; 250 micrograms/g dryweight). Untreated Wilson disease is always fatal. Lifelong treatment with anti-copper drugs are essential, D-penicillamine being the firstline therapy. Hereditary hemochromatosis (HH) is an iron overload disease inherited as an autosomal recessive trait. The frequency of the disease is high.

No other specific information about her treatment or outside health records was available. According to her husband, RS had been in her usual state of health until approximately 3 weeks prior, when she began having significant mental status changes. She first exhibited some difficulty finding words and later was noted to be putting food in a coffee maker. This spontaneously resolved after approximately 1 week; however, she rapidly developed slurred speech and began to make nonsensical statements. These manifestations also slowly improved but were followed by worsening speech deficit, difficulty walking, and impaired balance. During one of these episodes, she had an occurrence of incontinence. Her husband also noted an incident where her \"eyes were beating back and forth and the left side of her face was twitching.\" RS also had periods (according to her husband) where she \"did not seem to be interacting with her environment.\" These progressively worsened during the last week, and she completely stopped walking and talking 2 days prior to coming to the ED. According to her husband, RS had rheumatoid arthritis and no surgical history. Her family history was unknown except that RS's mother had \"seizures.\" RS had reportedly not used tobacco, alcohol, or drugs, and she was sexually active with her husband. Home medications included transdermal fentanyl 12 μg/hr patch changed every 72 hours; oxycodone-acetaminophen tablets 5-325 mg, two every 4 hours as needed for pain; prednisone 10 mg, one tablet daily; and megestrol 40 mg/mL suspension, 20 mL once daily for appetite stimulation. RS was admitted to an inpatient medical oncology service and evaluated by the oncology advanced practitioner (AP) on her second inpatient day. Upon exam, RS was nonverbal except for moaning in response to painful stimuli and to her sister's voice. Her vital signs were normal. She appeared ill but well-nourished, and she was mildly diaphoretic. Neurologic examination revealed that her pupils were slightly sluggish but equal, round, and reactive to light. Extraocular muscle movements were intact, but she did not move her eyes in response to commands. She tracked the AP and family members around the room with her eyes. Cranial nerve examination was intact with the exception of cranial nerves IX, X, and XI, which were difficult to examine given her inability to cooperate and open her mouth. Motor examination revealed increased tone throughout and intermittent, inconsistent resistance to passive movement. She was seen to move all four extremities spontaneously although not in response to commands. Deep tendon reflexes were intact and equal in all extremities. Examination of other body systems was as follows: there was dry, peeling skin on her lips, but her mucous membranes were moist and free of erythema or lesions. Her lungs were clear to auscultation bilaterally. Her heart rate and rhythm were regular, there were no murmurs, rubs, or gallops, and distal pulses were intact. Her abdomen was nondistended with normally active bowel sounds in all four quadrants. Her abdomen was soft, nontender to palpation, and without palpable masses. There was no peripheral discoloration, temperature changes, or edema, and examination of her skin was benign. <bWorkup</b On admission to the emergency department, serum laboratory studies were unrevealing for any potential causes of encephalopathy. Kidney and liver function were normal, making diagnoses of uremic and hepatic encephalopathies less likely. Cultures of the urine and blood were negative. Samples of cerebrospinal fluid (CSF) were obtained via lumbar puncture and were unrevealing for any abnormalities. Computed tomography (CT) of the head without contrast was negative for any acute intracranial process. Ultrasound of the right upper quadrant revealed a single, nonspecific, hypoechoic hepatic lesion. Computed tomography scans of the chest, abdomen, and pelvis demonstrated the primary malignancy in the upper lobe of the left lung, as well as possible metastatic disease within the left lung, right lung, and liver, and widespread osseous metastatic disease. Magnetic resonance imaging (MRI) of the brain performed 1 day after admission demonstrated numerous scattered punctate foci of enhancement throughout the supratentorial and infratentorial brain parenchyma, measuring at most 3 to 4 millimeters in diameter. There was no significant mass effect or midline shift. A paraneoplastic panel was sent to an outside laboratory and returned positive for antivoltage-gated potassium channel (VGKC) autoantibodies. <bDifferential Diagnosis</b Clinically, RS was exhibiting signs of encephalopathy, a broad term that indicates general brain dysfunction, the hallmark of which is altered mental status. Diagnosing encephalopathy is challenging, as many differential diagnoses must be considered. The clinician must consider metabolic derangements, toxic and infectious etiologies, psychiatric disorders, and less commonly, prion disorders and progressive dementia. Cultures of RS's blood and urine as well as other specialized endocrine tests were negative, decreasing the likelihood of a metabolic or infectious cause for her presentation. The abnormalities on her brain MRI were reviewed by a neuro-oncology team, who felt that the faint, nondescript nature of the visualized lesions was not suspicious for metastatic disease. Sequelae of seizures was also considered by neuro-oncology but dismissed given a grossly normal prolonged electroencephalogram. Some encephalopathies are caused by autoimmune or inflammatory mechanisms, which are confirmed by the presence of autoantibody markers and/or clear response to immunomodulatory treatment (Vernino, Geschwind, &amp; Boeve, 2007). These types of encephalopathies have been seen in patients with cancer and have thus been termed paraneoplastic. The presence of anti-VGKC antibodies on RS's paraneoplastic panel directed the inpatient medical oncology team toward a paraneoplastic neurologic disorder (PND) as the most likely diagnosis." }, { "id": "pubmed23n0325_8334", "title": "[Severe hemolytic anemia with tear drop red cells as initial manifestation of Wilson's disease].", "score": 0.009259259259259259, "content": "A 16-year-old girl was admitted for a detailed examination of hemolytic anemia in November 1995.

On examination, the patient was pale, jaundiced, and febrile (temperature of 39 degrees C). She had enlarged lymph nodes in the axillary and inguinal areas. There was moderate hepatosplenomegaly. Local skin examination revealed multiple erythematous, tender, and firm subcutaneous nodules of variable size (1-2 cm) on the lower abdomen. Some nodules were ulcerated, with oily yellowish brown discharge and overlying ecchymosis (Figures 1 and 2). Mucous membranes were free of lesions. Laboratory investigations showed pancytopenia, an elevated erythrocyte sedimentation rate (&gt;80 mm/h), normal renal function tests, abnormal hepatic function tests (alanine aminotransferase 172 U/L, aspartate aminotransferase 229 U/L, alkaline phosphatase 725 U/L, and total bilirubin 100 mmol/L [normal range 0-18 mmol/L]), conjugated bilirubin 45 mmol/L (normal range 0-5 mmol/L), and high triglycerides 855 mg/dL (normal range 20-200 mg/dL).

High concentrations (1832 Göttingen units/ml) of enzyme-inhibiting autoantibodies against the antioxidative enzyme manganese-superoxide dismutase (MSD) were demonstrated. The autoantibodies reduced the antioxidative action of the enzyme by more than 70% and favoured the oxidative cell damage in vitro. After bed-rest for one week without further treatment the symptoms improved and the abnormal laboratory values, including the autoantibodies against MSD, regressed. Autoantibodies against MSD are formed during an acute infection with EBV.

Diagnosis of idiopathic autoimmune hemolytic anemia requires both serologic evidence of autoantibody presence and hemolysis. Although most of the times it is considered idiopathic, several underlying causes have been identified, like autoimmune and connective tissue diseases, viral infections, drugs or hyper function of the immune system. To our knowledge, this is the first case in the international literature describing lecithin-induced autoimmune hemolytic anemia. This case report is to highlight a rare but dangerous adverse reaction to overdose of lecithin. A 38 year old white female from Greece, presented to our emergency room with progressive fatigue over a period of ten days and icteric discoloration of her skin and conjunctiva. The patient had been taking lecithin supplements (1200 mg, 3 capsules a day) over a period of ten days for weight loss. She reports that the last 3 days, prior to the examination, she took 5 capsules/day, so that the supplement would take effect more rapidly. Her past medical, social and family history showed no disturbance. Relatives of the patient were requested to submit any blood-tests taken over a period of 20 days prior to the onset of symptoms caused by Lecithin. All tests proved that all functions were within normal scale. Her physical examination revealed pallor and jaundice without palpable hepatosplenomegaly. Blood biochemistry tests showed total bilirubin 7.5 mg/dl, with indirect bilirubin 6.4 mg/dl and complete blood count showed hemoglobin 7.6 g/dl with blood levels 21.4%. In every case of idiopathic autoimmune hemolytic anemia the administration of pharmaceutical substances should always be examined, except for the standard reasons that cause it. In this case the cause of hemolysis was attributed to the excessive intake of lecithin capsules for the loss of body weight. It is important that clinicians and immunologists are aware of this adverse effect." } ] } } }

Thirty-three patients with delayed panfacial fractures were treated in the Maxillofacial Trauma Center of Peking University, School and Hospital of Stomatology between 1998 and 2004. Each patient was examined by computed tomography (CT) scans before operation. For those who had no severe opening restriction, dental impressions were taken to fabricate dental casts. For those with severely comminuted fractures, 3-dimensional (3D) models of the facial skeleton were used. Re-establishing the continuity of the mandible was the first step and then used as a platform to reconstruct the maxillary fractures via maxillomandibular fixation after Le Fort I osteotomy. The third step was to restore the mid- and upper-facial width and projection by coronal approach to expose the zygomatic complex and frontal bone/sinus and/or naso-orbito-ethmoid (NOE) fractures. There were 3 types of mandibular fractures that affected the treatment plan: 1) type I, mandibular body/symphysis fracture(s) (17/33, 51.52%); 2) type II, mandibular angle and/or condylar fracture(s) (6/33, 18.18%); and 3) type III, both mandibular body/symphysis and angle/condylar fractures (10/33, 30.30%). Fourteen cases were associated with NOE fractures (42.42%) and 3 cases had frontal sinus fractures (9.1%). Twelve cases had enophthalmos (36.36%) and 3 lost 1 eyeball. The order of treatment was dependent on the mandibular fracture type. For type I fractures, reconstructing the mandibular arch was the first step. For type II fractures, repairing the angle, ascending rami, and condylar areas was the first step. For type III fractures, when both mandibular height and arch were disrupted, freeing the malunited angle or condyle was the first step before restoring the mandibular arch form. Reconstruction of the mandibular height and projection was then carried out. For all 3 types, the second step was to restore the mid- and upper facial width and projection by reducing the zygomatic complex and frontal bone/sinus or NOE fractures. Maxillary fixation across the Le Fort I level was the last step. Le Fort I osteotomy was used for all 33 cases. Bone grafts and soft tissue suspension also were used. Twenty-one cases (63.64%) had good results, 7 (21.21%) cases were acceptable, and 5 (15.15%) were not good. There were 7 cases (21.21%) that still had soft tissue problems that needed secondary operations. Reconstruction of the mandible first with Le Fort I osteotomy is a good way to treat delayed panfacial fractures. Computed tomography and 3D CT, model surgery, and occasionally 3D models are necessary aids for diagnosis and treatment. Soft tissue problems, including lacerations and asymmetries, were often the factors that caused an unfavorable outcome." }, { "id": "pubmed23n0794_2527", "title": "Etiology, incidence and patterns of mid-face fractures and associated ocular injuries.", "score": 0.019419306184012067, "content": "A prospective study on mid-face fractures was carried out in the Department of Oral and Maxillofacial Surgery at College of Dentistry, Indore, from August 2007 to September 2009 to analyze etiology, incidence and patterns of midface fractures and associated ocular injuries.

Males far outnumbered females in a ratio of 9:1. Thirty-three patients (63.46%) had unilateral NOE fracture, while the rest 19 (36.54%) had bilateral NOE fracture. Sixteen (30.76%) cases were classified as Type I, 35 (67.30%) as Type II, and 1 (1.92%) as Type III. Road traffic accidents were the most common cause of NOE fractures (69%), followed by fall (17%) and assault (10%). The most common neurological injury to be associated with NOE fractures was pneumocephalus (29%), followed by diffuse axonal injury (8%). Telecanthus (100%) was found to be the primary clinical feature in patients of NOE fracture, followed by a depressed nasal bridge (92%). Fracture of the nasal bone was invariably associated with NOE fracture. Complications observed due to untreated NOE fractures included a shortened and retruded nose, shortened palpebral fissures, telecanthus, and enophthalmos. Contemporary management of NOE complex fractures demands precise diagnosis and immediate surgical management with anatomic reduction and rigid fixation of the involved bone segments. With an improvement in socioeconomic status and increased awareness among maxillofacial surgeons, hopefully, a greater number of NOE fracture patients will avail the benefits of open reduction in future." }, { "id": "pubmed23n0873_4203", "title": "Fractures in the Maxillofacial Region: A Four Year Retrospective Study.", "score": 0.014916269269158258, "content": "The incidence of maxillofacial injuries is on the rise due to motor vehicle accidents and increased incidence of violence in recent times.

All the cases were successfully managed by ORIF under general anaesthesia (GA). Complications were noticed in 6.8% of cases in the form of reactive implants in 3.6%, deranged occlusion in 1% and infection at operated site in 1% cases which were managed satisfactorily. The findings of this study reveal sharp annual increase in the number of cases of maxillofacial trauma.

There were 31 patients who were reconstructed for the first time and 6 for the second time. Typical bicoronal and subciliary incisions and intra-oral approach were employed to expose all the fractured sites. According to the fractured position and the degree of deformity and dislocation, the orbito-zygomatic fracture was repositioned after osteotomy and rigid fixation, or the healed fragments were trimmed with a burr and the depressed fragments were filled with autogenous bone such as ilium, cranial outer table or Medpor in order to reconstruct orbital wall framework; the orbital walls were repaired to correct the enophthalmos with autogenous bone or Medpor after the herniated orbital contents were released. The medial canthal ligament was anchored superior-posteriorly to the lacrimal fossa with transnasal wires fixation or fixed with titanium miniplates and nails. The 36 patients' incisions obtained healing by first intention after the operation, and 1 case failed because of wound infection from maxillary sinusitis. There were 24 patients who were cured successfully with facial appearance and function improved significantly. During the follow-up for 3-6 months, no complication was found such as dislocation of the implant, rejection and infection. Two patients still showed slight enophthalmos while 3 patients with canthus dislocation regained improved appearances but not satisfactory. At 6 months after operation, the CT scan conducted in 3 patients with autogenous bone and Medpor grafting showed all fractures were fixed rigidly. Surgical reduction combined with bone grafting is a satisfactory method for the correction of secondary orbital bone deformity, and the repair of canthus dislocation and correction of enophthalmos should be considered at the same time.

The majority of the traumatic events occurred in children within the 8-10 years of age-range; 1085 teeth were injured, of which 975 permanent teeth (89.9%) and 110 primary teeth (10.1%). The most common dental lesions were the coronal fractures (complicated and not complicated) while the most frequently involved teeth were the upper central incisors; 11% of patients were also treated for maxillo-facial fractures. A protective helmet was worn only in 3% of the cases; not one patient wore a mouth-guard. The use of helmets was more frequent in children and adolescents riding racing-bikes competitively, compared to those who were mountain bikers (p &lt; 0.05).

Where the support surfaces of most prostheses remain limited, even punctiform, the originality of the Goodfellow prosthesis lies in the fact that the prosthetic condyle, whatever the flexion angle is, leans against a mobile prosthetic meniscus with spheric superior concavity of the same radius as the condylian radius, which increases considerably the prosthetic leaning surfaces and therefore lessens the pressure constraints. The superior surface, concave, of this prosthetic meniscus takes charge of the rolling, where the inferior plane surface realizes the gliding on the metallic tibial plate. The total conformity of the components minimizes the forces of friction.Between July 1988 and March 1993, 24 patients underwent the placing of UCP. Three patients died and 2 were lost of sight. 19 patients could be seen again or checked, corresponding of 21 operated knees. Two knees benefited from the start from UCP (medial and lateral) and 2 knees had a UCP in the first instance and then a second UCP in the compartment left safe primarily. For the 21 UCP, there are 16 medial and 3 lateral. Our mean drawback is of 3 years and 3 months, all the drawbacks being superior to 1 year and 4 months. The mean age is of 64 years. There were 17 female and 2 male patients. The mean weight is of nearly 80 kg (79,8) and nearly 52% of the operated patients have an important overweight (Body Mass Index superior to 30). Preoperative clinical analysis. It is based on a retrospective study of files using the quotation described by AUBRIOT for the «GUEPAR» group. This one establishes a gradation of four levels for each of the three criteria retained (Pain, Mobility, Instability), thus determining a global result imposed by the lowest level retained.For walking, other factors than just the state of the operated knee may intervene, this being the reason why it doesn't show in this chart. The GUEPAR group quantifies it with letters A, B, C, D.Concerning pain, all 21 knees were quoted as \"Bad\" in preoperative. Pain constitutes the decisive argument for the operative indication. In our series, only one knee had an average amplitude, all the others had a mobility superior to 89°. In 5 cases there was a flessum between 11 and 20° (penalizing of a level). Concerning walking and stability, they were taken into account, thanks to a precise questionnaire about the daily life acts. Concerning the walking perimeter, it was found as unlimited (A) in 1 case, superior to 500 m (B) in 2 cases, inferior to 500 m (C) in 17 cases and limited to home (D) in 1 case. The early after effects. At the end of the intervention, the knee is placed into a splint with limited flexion. As soon as the second day the patient is sat on the border of his bed. The first partial support at the third of the body weight is authorized between the fourth and the fifth day, when at the same time flexion exercises on electrical splint are started, as soon as the Redon draining is removed. The average hospitalization length was of a fortnight. Among secondary late complications and retakes, let us stop on meniscal luxations which constitute a specific complication of the Oxford arthroplasty. They concern 3 times the medial compartment and 4 lateral compartment. They happened in 1 case early, at D 22, in 3 cases within the 6 first months and in 3 cases after 2 years. They were treated : 3 times by reduction under general anæsthetic, no more ; 3 times changing the meniscusus for a meniscusus of superior size and once by placing a total prosthesis at the place of the UCP. The deteriorations of the opposed compartment not prosthesized occured in three cases. They were treated by unicompartmental additional arthroplasty in two cases and by total prosthesis in the third case. The clinical results on pain are very satisfactory as from the early check up onwards we have 17 successes (no pain 11 cases and occasional pains 6 cases) and as after 3 years and 5 months in average, we have 19 successes (no pain : 10 cases - occasional pain : 9 cases). At the maximal drawback, the mobility is quoted very good in 7 cases and good in 13 cases, mean in 1 case. At the latest check up, we note an excellent stability in 17 cases and good in 3 cases, that is to say 20 successes and 1 case of stability quoted as mean. At the latest check up we note 17 successes (A and B) and 4 relative failures (C) concerning the quality of walking.At the question «are you pleased with the intervention and would you advise it to a friend?» and with the nuance «very pleased» and «simply satisfied», we get 10 cases «very pleased», 8 cases «pleased» and 3 cases «moderately satisfied»; only those 3 cases advise against the intervention. The radiological results are less satisfying as they show frequent imperfections : • for the 16 medial UCP : only 9 cases hypocorrected or normo axed, but 1 case strongly hypocorrected (residual varus of 7°) and 6 hypercorrected cases. • for the 5 lateral UCP : 3 normo-axed cases, 1 case strongly hypocorrected (residual valgus of 6°) and 1 case strongly hypercorrected (10° varus). • the failures due to rapid deterioration of the non prosthetized compartment occurred on hypercorrected knees. • on 21 knees, 14 borders of tibial plate were noticed, out of which 9 had no plate displacement and 5 had a slight displacement, at the origin of a small angular loss. • accumulations of cement on the tibial side, towards the back or in medial were noticed in 8 cases, which explains a slope of the tibial plate to the back inferior to 5° in 11 cases (should be of 7°). • 4 femoral components seem to be too posterior and one shows curved.In total, only 7 cases out of 21 were estimated with no peculiarities on the radiological point of view. It seems difficult to place a UCP well. The meniscal luxations are favored by an alignment rotational defect of the tibial plate, specially for the lateral UCP, the meniscus coming to hit the lip of the tibial plate during the lifting from a sitting position. For 5 of these luxations, we must recognize the existence of a ligamentary collateral laxity which should have altered the surgical indication either to an osteotomy, or to a total arthroplasty. Conclusions. Under the condition of respecting the absolute counter indications, of thoroughly evaluating the relative counter indications and of reducing at the best the defects linked to the surgical technique, the unicompartmental arthroplasty, including that of Oxford, gives good functional results after more than three years. In our series, the result on pain is constant if we exclude the cases with risk with ligamentary laxity and that of centered gonarthrosis at obese subject, that is to say 15 successes on 15 knees thus selected retrospectively. The gain on mobility is weak, of 5° in average. The result on stability is, as for pain, excellent, if we exclude the cases with risk, as we get then also 15 successes on 15 knees. Concerning the global result according to the quotation of Aubriot-Guepar, we note 14 successes and 1 relative failure. 4 knees were bad indications and should have benefited from a total arthroplasty or from an osteotomy.

Our case is unusual because of the acute presentation of the Brodie's abscess with acute leg pain and acute swelling without any preceding trauma; to the best of our knowledge, this presentation has not been reported before. A 17-year-old white boy presented to our out-patient clinic with a 6-month history of pain in his left knee joint of insidious onset. There was no history of trauma to the extremity. After performing physical and radiological (X-ray) examinations, we initially diagnosed medial meniscus damage. One week later he presented to our emergency department with acute sudden increase in the pain and swelling of his left knee, and pain and swelling of his left leg, without any trauma. Deep vein thrombosis and beginning leg compartment syndrome from ruptured Baker's cyst were initially diagnosed. Magnetic resonance imaging was performed and Brodie's abscess was the most probable diagnosis. We performed open surgical debridement and curettage with drainage of the abscess and administered postoperative antibiotics. He presented to our out-patient clinic 3 months postoperatively, where he was pain-free with no residual local tenderness. In cases of sudden acute increase in joint or extremity pain or swelling that has been insidiously present for months, Brodie's abscess should be considered as one of the differential diagnoses, as it may present acutely in cases with accompanying fasciitis and myositis and be clinically mistaken for deep vein thrombosis or limb compartment.

The obtained data is used also to evaluate the arthroscopic finding in relation to age and sex. MATERIAL AND METHODS The arthroscopic findings of patients who underwent surgery in 2013-2014 period (1.1.2013-31.12.2014) at the Department of Trauma Surgery of České Budějovice Hospital, a.s. and in 2014 (1.1.-31.12.2014) at the Department of Orthopaedics and Traumatology of Písek Hospital, a.s. were evaluated. In total, 1 021 patients underwent surgery, with the mean age of 44 years. The patients were not selected. The group includes all the patients who underwent surgery, including those in whom repeat arthroscopy was performed, in the respective period of time, regardless of the mechanism of difficulties. A preoperative MRI scan was carried out in 470 patients. The referring physician was present during the examination. In all the patients undergoing surgery, the main clinical preoperative sign was examined based on the documentation, namely in the following order - hemarthros, locked knee, hydrops or merely a pain. In the arthroscopic finding, the medial meniscal lesion - anterior and posterior horn, and complete tear was assessed. The same was done for lateral meniscus. In anterior cruciate ligament - ACL - partial or complete tear was assessed. We identified the frequency of findings in relation to age and evaluated the correlations between the clinical signs and the arthroscopic finding. We calculated the sensitivity and specificity of hemarthros as a sign of ACL tear. The analysis was conducted based on the medical history in medical record documentation and the surgical protocol. The cartilage was not assessed. RESULTS Analysis of clinical and anamnestic signs in relation to arthroscopic findings 1. Negative arthroscopic findings (potential cartilage damage with no damage to other soft structures and normal arthroscopic findings) are in 83% accompanied by a mere knee pain. 2. High percentage of isolated locked joint (15%) in negative findings 3. Complete ACL tears are most frequently reported in the under-35 age category - 43% of 191 men who underwent surgery and 33% of 102 women. 4. Isolated injuries to ACL without the meniscus tear are frequent in younger patients - 30% - 40% of the total number of patients with injured ACL. 5. In patients older than 56 years of age the ACL damage is accompanied by concurrent meniscus tear (96% in men, 100% in women). 6. Sensitivity of hemarthros (68%) for complete ACL tear. Specificity of the presence of hemarthros in complete ACL lesions (91%) indicates that there are also complete ACL tears with no hemarthros whatsoever in the medical history. For partial tears the values of sensitivity and specificity are 27% and 67%, respectively. In partial tear, the presence of hemarthros is not a diagnostic lead. 7. In 15% of negative findings a \"locked knee\" was present. It was not a genuinely locked knee, but rather an antalgic position. Not every locked knee must necessarily mean a meniscus lesion or ACL tear. 8. Isolated meniscus tear is in 75% accompanied only by pain. 9. In our group of patients, isolated osteoarthrosis or malacic cartilage without any damage to ligaments or menisci was rare - only in 22 cases (2% of the entire group). DISCUSSION There are lots of studies which focus on comparing the clinical findings with perioperative pathology of knee joint and the importance of pre-operative clinical examination. Our extensive retrospective study proved that in 56-plus age category virtually each ACL injury is accompanied by a meniscal lesion, which can be explained by a possible ACL damage at a young age and subsequent instability resulting in meniscus tear or frequent presence of degenerative meniscal changes at an older age. A small number of isolated degenerative cartilage damage was established (2%). We fully agree with the authors who prove that the degenerative cartilage changes are ever since the very beginning accompanied by changes of the other soft structure of the knee. We revealed a high percentage of locked knee joint in negative arthroscopic findings. According to the clinical pre-operative examination, the locked knee does not automatically mean the meniscal lesion or ACL tear. In agreement with the others we prove a close association between hemarthros and ACL injury. CONCLUSIONS 1. A clinical examination, a detailed medical history is necessary 2. With hemarthros in medical history, there is a likelihood of complete ACL tear. Conversely, even a seemingly trivial knee sprain without hemarthros or locked knee can mean the ACL tear. 3. Where a mere pain is present, it mostly indicates an isolated meniscal damage or a negative finding. 4. Degenerative cartilage changes are accompanied by degeneration of menisci and ligaments. 5. Our group of patients did not include any case of hemarthros in the medical history with a negative arthroscopic finding. Hemarthros always indicated a more serious damage to knee soft structures.

QUESTIONS ASKED: Does arthroscopic lavage improve motor function and pain associated with OA of the knee?Does arthroscopic debridement improve motor function and pain associated with OA of the knee?If evidence for effectiveness can be established, what is the duration of effect?What are the adverse effects of these procedures?What are the economic considerations if evidence for effectiveness can be established? Osteoarthritis, the most common rheumatologic musculoskeletal disorder, affects about 10% of the Canadian adult population. Although the natural history of OA is not known, it is a degenerative condition that affects the bone cartilage in the joint. It can be diagnosed at earlier ages, particularly within the sports injuries population, though the prevalence of non-injury-related OA increases with increasing age and varies with gender, with women being twice as likely as men to be diagnosed with this condition. Thus, with an aging population, the impact of OA on the health care system is expected to be considerable. Treatments for OA of the knee include conservative or nonpharmacological therapy, like physiotherapy, weight management and exercise; and more generally, intra-articular injections, arthroscopic surgery and knee replacement surgery. Whereas knee replacement surgery is considered an end-of-line intervention, the less invasive surgical procedures of lavage or debridement may be recommended for earlier and more severe disease. Both arthroscopic lavage and debridement are generally indicated in patients with knee joint pain, with or without mechanical problems, that are refractory to medical therapy. The clinical utility of these procedures is unclear, hence, the assessment of their effectiveness in this review. LAVAGE AND DEBRIDEMENT: Arthroscopic lavage involves the visually guided introduction of saline solution into the knee joint and removal of fluid, with the intent of extracting any excess fluids and loose bodies that may be in the knee joint. Debridement, in comparison, may include the introduction of saline into the joint, in addition to the smoothening of bone surface without any further intervention (less invasive forms of debridement), or the addition of more invasive procedures such as abrasion, partial or full meniscectomy, synovectomy, or osteotomy (referred to as debridement in combination with meniscectomy or other procedures). The focus of this health technology assessment is on the effectiveness of lavage, and debridement (with or without meniscal tear resection). THE MEDICAL ADVISORY SECRETARIAT FOLLOWED ITS STANDARD PROCEDURES AND SEARCHED THESE ELECTRONIC DATABASES: Ovid MEDLINE, EMBASE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews and The International Network of Agencies for Health Technology Assessment. THE KEYWORDS SEARCHED WERE: arthroscopy, debridement, lavage, wound irrigation, or curettage; arthritis, rheumatoid, osteoarthritis; osteoarthritis, knee; knee or knee joint. TIME FRAME: Only 2 previous health technology assessments were identified, one of which was an update of the other, and included 3 of 4 randomized controlled trials (RCTs) from the first report. Therefore, the search period for inclusion of studies in this assessment was January 1, 1995 to April 24, 2005. EXCLUDED WERE: case reports, comments, editorials, and letters. Identified were 335 references, including previously published health technology assessments, and 5 articles located through a manual search of references from published articles and health technology assessments. These were examined against the criteria, as described below, which resulted in the inclusion of 1 health technology assessment and its corresponding update, and 4 articles (2 RCTs and 2 level 4 studies) for arthroscopic lavage and 8 papers (2 RCTs and 6 level 4 studies) for arthroscopic debridement.

Arthroscopic lavage or debridement, with or without meniscectomy, for the treatment of motor function symptoms and pain associated with OA of the knee. Studies in which there was a comparison group of either diseased or healthy subjects or one in which subjects were their own control were included. Comparisons to other treatments included placebo (or sham) arthroscopy. Sham arthroscopy involved making small incisions and manipulating the knee, without the insertion of instruments. IN EARLY OA OF THE KNEE WITH PAIN REFRACTORY TO MEDICAL TREATMENT, THERE IS LEVEL 1B EVIDENCE THAT: Arthroscopic lavage gives rise to a statistically significant, but not clinically meaningful effect in improving pain (WOMAC pain and VAS pain) up to 12 months following surgery. The effect on joint function (WOMAC function) and the primary outcome (WOMAC aggregate) was neither statistically nor clinically significant. IN MODERATE OR SEVERE OA OF THE KNEE WITH PAIN REFRACTORY TO MEDICAL TREATMENT, THERE IS: Level 1b evidence that the effect on pain and function of arthroscopic lavage (10 L saline) and debridement (with 10 L saline lavage) is not statistically significant up to 24 months following surgery.Level 2 evidence that arthroscopic debridement (with 3 L saline lavage) is effective in the control of pain in severe OA of the medial femoral condyle for up to 5 years.For debridement in combination with meniscectomy, there is level 4 evidence that the procedure, as appropriate, might be effective in earlier stages, unicompartmental disease, shorter symptom duration, sudden onset of mechanical symptoms, and preoperative full range of motion. However, as these findings are derived from very poor quality evidence, the identification of subsets of patients that may benefit from this procedure requires further testing.In patients with pain due to a meniscal tear, of the medial compartment in particular, repair of the meniscus results in better pain control at 2 years following surgery than if the pain is attributable to other causes. There is insufficient evidence to comment on the effectiveness of lateral meniscus repair on pain control. Arthroscopic debridement of the knee has thus far only been found to be effective for medial compartmental OA. All other indications should be reviewed with a view to reducing arthroscopic debridement as an effective therapy. Arthroscopic lavage of the knee is not indicated for any stage of OA. There is very poor quality evidence on the effectiveness of debridement with partial meniscectomy in the case of meniscal tears in OA of the knee." }, { "id": "InternalMed_Harrison_26084", "title": "InternalMed_Harrison", "score": 0.009174311926605505, "content": "OA is the most common cause of chronic knee pain in persons over age 45, but the differential diagnosis is long.

Anserine bursitis, medial and distal to the knee, is an extremely common cause of chronic knee pain that may respond to a glucocorticoid injection. Prominent nocturnal pain in the absence of end-stage OA merits a distinct workup.

Because the patient had been residing in another state between July and January, rheumatologic and orthopaedic evaluations of the knee, including a magnetic resonance imaging (MRI), had been performed at a geographically distant (but affiliated) institution.

The mean preoperative and postoperative knee scores were 64.6 (range 47 to 80) and 97.5 (range 89 to 100), and the mean functional scores were 59.6 (range 45 to 80) and 92.1 (range 70 to 100), respectively (p&lt;0.05). All the patients had an excellent knee score, while functional scores were excellent in 27 patients (71.1%) and good in 11 patients (28.9%). Postoperative radiographic measurements showed that the position of the femoral components was within acceptable ranges in all the patients with a mean of 3 degrees valgus (range 5 degrees valgus to 8 degrees varus) and 0.5 degrees extension (range 3 degrees extension to 2 degrees flexion). The positioning of the femoral components in relation to the mechanical axis was central in 30 patients and 2-mm lateral (range 2 mm medial to 4 mm lateral) in eight patients. The position of the tibial components was also within acceptable ranges in all the patients with a mean of 1.5 degrees varus (range 2 degrees varus to 2 degrees valgus) and a mean posterior inclination of 6.2 degrees (range 5 degrees to 7 degrees). All the tibial components showed full congruency with the medial, lateral, anterior, and posterior planes, except for one which had a 4-mm undersizing in the anterior plane. The polyethylene insert was central and parallel to the tibial component in all the patients. No osteophytes or cement debris that might lead to impingement were observed. All the components remained in position until the final controls. Complications such as insert dislocation, infection, pulmonary embolism, deep venous thrombosis, or neurovascular injury were not observed. None of the patients required revision surgery.

Surgical treatment mainly consists of debridement. The main aim of the present study was to assess the efficacy of arthroscopic treatment of osteoarthritis of the elbow on Andrews-Carson score. Secondary objectives comprised assessment of the impact of associated procedures and of epidemiological factors on functional results. A prospective multicenter study involving 8 centers, in a symposium held by the French Society of Arthroscopy (SFA), included patients treated by arthroscopy for primary or secondary osteoarthritis of the elbow between January 2017 and March 2018, with a minimum 6 months' follow-up. Clinical assessment was based on change in Andrews-Carson functional score (AC), specific to osteoarthritis of the elbow, and on other functional scores: QuickDash (QD), Patient-Rated Elbow Evaluation (PREE), Mayo Elbow Performance Score (MEPS) and Self-Evaluation Elbow (SEE). Progression in pain on visual analog scale (VAS) and range of motion (RoM) was also assessed. Initial imaging work-up comprised standard X-ray and CT arthrography; paraclinical follow-up was based on X-ray. The impact of the following procedures associated to arthroscopic debridement was analyzed: radial head resection, ulnar nerve release, humeral fenestration, lateral ramp release, and medial collateral ligament posterior bundle release. The functional impact of epidemiological factors (age, handedness, manual occupation, smoking, body-mass index, and work accident/occupational disease status) and radiographic factors (foreign bodies, joint impingement, osteophytes, and fossa filling) was also assessed. The series comprised 87 patients: 75 male (86.2%); mean age, 49 years (range, 18-73 years). Arthroscopic debridement significantly improved all functional scores at a minimum 6 months, and notably the specific AC score: 113.6±25.4 (40-180) versus 178.7±20.2 (110-200) (P&lt;0.0001). Pain diminished significantly: 6.4±2.1 (0-10) versus 1.7±1.8 (0-8) (P&lt;0.0001). RoM increased significantly: flexion/extension, 93.44±20.5° (5-130°) versus 124.2±13.8° (90-160°) (P&lt;0.0001); pronation/supination, 147.6±25.6° (60-180°) versus 162.5±20.6° (100-180°) (P&lt;0.0001). Strength (kg) increased in flexion (8.8±4.0 (4 to 20) versus 15.3±5.1 (3 to 32) (P&lt;0.0008) and in grip [33.1±12.3 (10 to 58) versus 42.1±14.0 (2 to 68) (P&lt;0.0001)]. Epidemiologically, males showed better recovery than females for both pain and strength. There was a significant positive impact of manual work on functional recovery, pain and also strength. There was a significant negative impact of work-accident/occupational disease on pain and strength. Regarding associated procedures, lateral ramp debridement improved AC score, with a gain of 75.4±25.3 points (-5 to 110) vs. 49.6±23.5 (10 to 100) (P&lt;0.0001), and pain on VAS, with a fall of -5.6±2.1 points (-10 to -1) vs. -3.6±3.0 (-8.5 to 1) (P=0.0013). Ulnar nerve release, radial head resection and humeral fenestration had no positive impact. Preoperative foreign body was a factor for good prognosis. Cartilage wear, especially in the humeroulnar compartment, was associated with poorer functional results. Arthroscopic treatment of osteoarthritis of the elbow significantly improved clinical results at 6 months, with significant improvements in functional scores, pain, strength and range of motion. Gender, type of work and work-accident/occupational disease status influenced clinical results. Lateral ramp release is an often overlooked technical factor improving functional results. Radiologically, the best candidates are those presenting with a foreign body and no humeroulnar impingement. III, Prospective observational multicenter cohort study." } ] } } }

Ten community-based hospitals were chosen as representatives in each part of Thailand to enroll patients into the study. Patients aged over two years old who presented with fever at the participating hospitals during year 1991-1993 were eligible for the study.

Patient 1 (81-year-old female) is a villager, with a rat bite, while Patient 2 (77-year-old male) and Patient 3 (84-year-old female) are farmers and were infected probably during agriculture work. Patient 4 (40-year-old male US citizen) was infected while traveling in Thailand. They had chief complaint of fever, headache, and myalgia and showed manifestations of hyperbilirubinemia (mean, 4.35 mg/dL), thrombocytopenia and acute kidney injury (AKI). All patients were diagnosed by polymerase chain reaction using blood and/or urine samples and a microscopic agglutination test for the anti-Leptospira antibody.

Tourism has also resulted in an increasing number of cases diagnosed in Europe, America, and Oceania. In this review we focus on the risk of the travel-associated acquisition of P. knowlesi malaria. A search of the literature in PubMed was carried out to identify articles and literature on the distribution of P. knowlesi infections in Southeast Asia and details of its acquisition and importation by travellers to other continents. The cut-off date for the search was December 1, 2013. Search words used were: \"Plasmodium knowlesi\", \"Plasmodium knowlesi infections\", \"Plasmodium knowlesi travellers\", \"Plasmodium knowlesi prevalence\", \"Plasmodium knowlesi host\", \"Plasmodium knowlesi vector\" \"Plasmodium knowlesi RDT\", and \"Plasmodium knowlesi Malaysia\". Traveller numbers to Malaysia were obtained from the Tourism Malaysia website. A total of 103 articles were found. Using a selection of these and others identified from the reference lists of the papers, we based our review on a total of 66 articles. P. knowlesi malaria appears to be the most common malaria species in Malaysian Borneo and is also widely distributed on the Malaysian mainland. Furthermore, locally transmitted cases of P. knowlesi malaria have been reported in Thailand, the Philippines, Vietnam, Singapore, Myanmar, Indonesian Borneo, and Cambodia. Two cases have been reported from non-endemic countries in Asia (Japan and Taiwan) in people with a history of travel to Malaysia and the Philippines. Twelve cases were imported to their home countries by travellers from other continents: two from the USA, two from the Netherlands, two from Germany, and one each from Spain, France, Sweden, Finland, Australia, and New Zealand. In most cases, the infection was associated with a trip to or near forested areas. The symptoms were fever (n=12), headache (n=6), chills (n=6), nausea (n=4), myalgia (n=3), back pain (n=3), abdominal problems (n=1), anorexia (n=2), fatigue (n=2), malaise (n=1), arthralgia (n=1), sore throat (n=1) vomiting (n=2), and jaundice (n=1). All patients were treated successfully with currently available antimalaria treatments. The identification of the pathogen by microscopy can be problematic due to the morphological similarity of P. knowlesi to Plasmodium malariae. P. knowlesi appears to be a threat not only to the local population in Malaysia, but also to the estimated 25 million annual tourists and occupational travellers to Malaysia, especially those who visit rural, forested areas of the country.

In this report, two non-immunocompromised patients who developed invasive pulmonary aspergillosis are presented. Case 1: A 63-year-old man complained of productive cough and fever. He received antibiotic therapy from his personal physician. This symptoms did not respond, however, and dyspnea developed. He was then transferred to our hospital, about one month after the onset. The chest X-ray showed a meniscus shadow suggesting an aspergilloma in the right upper lung field and an infiltrative shadow in the remaining right lung field. Case 2: A 78-year-old man was admitted because of dyspnea, productive cough and appetite loss over the previous three months. The chest X-ray showed a meniscus shadow in the left upper field, an infiltrative shadow in the left lower field and a right pleural effusion sign was also observed. Both cases were diagnosed as having aspergillosis, early in their illness, by the detection of aspergillus antigen in their sera and histopathological and cultural studies of specimens obtained by TBLB. Both improved with intravenous amphotericin B (30 mg/day) and intravenous ulinastatin (200000 IU/day) administration.

On May 28th, 2015, the first patient of imported MERS to China was admitted to Department of Critical Care Medicine of Huizhou Municipal Central Hospital. The clinical features and treatments of this patient were analyzed. (1) A 43 years old male of South Korean nationality was admitted with the complaint of back ache for 7 days and fever 2 days with the following characteristics: back ache 7 days ago, without fever or cough or expectoration. He had been suspected to suffer from infection of Middle East respiratory syndrome coronavirus ( MERS-CoV ) by the Disease Control Department of South Korea, but no specific treatment was given. He had fever for 2 days with maximum body temperature of 39.7 centigrade. He had no chills, cough, expectoration, short of breath, abdominal pain, diarrhea, frequent micturition, or urgency or pain of urination, and no sore throat. The patient had a history of exposure to MERS-CoV patient. He was considered to be a patient of the second batch of South Korean epidemic. (2) Auxiliary examination: 3 copies of throat swab specimens for virus nucleic acid detection were performed by the Disease Prevention Control Center of China ( China CDC ), and they were positive on May 29th, 2015, and also for serum, sputum and stool. Based on the results of whole genome sequence analysis, the virus strains were implicated to be derived from Riyahh and Jeddah regions of Saudi Arabia. On admission, the patient's blood test showed that the white blood cell count was low ( 3.22×10(9)/L ), the proportion of the neutrophils was high ( 0.73 ), and that of the platelet was low ( 81×10(9)/L ). On admission, the patient's chest X-ray showed that a small amount of infiltration in the lung. (3) TREATMENT: a high-flow nasal cannula ( HFNC ) with oxygen concentration of 0.50-0.80 was given, with a flow rate was set at 60 L/min if tolerated. It was changed to a low flow oxygen inhalation nasal cannula on the 20th day, and oxygen treatment was stopped on the 24th day. Ribavirin 2.0 g was given as the first dose, and was switched to 600 mg every 8 h ( q8h ), and it was reduced to 600 mg q12h after 10 days, and extenuated since the 13th day. Ceftriaxone was added on the 4th day with 2.0 g a day , and it was changed to meropenem 2.0 g, q8h on the 7th day for 2 weeks. Gamma globulin was given for 7 days ( 20 g, qd ). Thymosin-α1 was given on the 8th day for 2 weeks. Interferon was given once a week, but only one dose was used. At the same time symptomatic treatment such as methimazole and liver protection therapy were given. (4) Patient began to cough at admission, and it disappeared on the 18th day. There was no sputum at first, then a small amount of sputum with a little blood appeared after the admission. Then there was cough without sputum. Mild shortness of breath and diarrhea after exertion were noticed. He had no chest pain, difficulty in breathing or other symptoms. There was dullness on percussion in both sides of chest, and it disappeared gradually. Fine moist rales were detectable in scapular area and interscapular area on the 5th day, and they disappeared after 3 days. Breath sounds on both sides was weak, and it became more obvious in the right lung after 5 days, and returned to normal after 18 days. He had a sustaining fever for 1 week with the maximum temperature of 39.5 centigrade, then the body temperature returned to normal. The viral nucleic acid test as performed by the Center for Disease Control of Guangdong ( CDC, Guangdong ) showed that the pharyngeal swab cultured turned negative on the 3rd day, that of serum specimens turned negative on the 8th day, that of stool specimen after 2 weeks, and it was persistently positive for sputum culture until 5 days before discharge. The oxygenation index gradually increased, and it was over 300 mmHg ( 1 mmHg = 0.133 kPa ) after 15 days. Pleural effusion was rapidly increased during the first week as shown by chest X-ray films, and it began to be absorbed gradually in the second week, but it was not completely absorbed until discharge. The disease course of the reported patient was short, with an acute onset, with fever as the chief complaint, but there were no respiratory symptoms, though there were high fever, cough, shortness of breath, diarrhea and other clinical symptoms after admission. Virus in sputum disappeared after treatment, but pleural effusion was not completely absorbed. Negative test for virus in sputum was late, indicating that clearance of virus was slow from the lungs.

Associated diseases observed were chronic obstructive pulmonary disease (COPD) in 6 patients, human immunodeficiency virus (HIV) infection in 3 and polymyalgia rheumatica in 1. Four patients had received oral corticotherapy for COPD for over a year (mean dose 13 mg/day of prednisone or equivalent). The main reason for consultation was an increase in dyspnea in the patients with COPD (6/6) and fever in those with HIV (3/3). Mean time between onset of symptoms and diagnosis was 5 weeks. In 8 patients, the infection occurred outside the hospital setting. The infection was restricted to the lung in 9/10; in the remaining case, the central nervous system (CNS) and subcutaneous tissue were affected. Lobar or multilobar consolidation was the most frequent radiographic pattern found (6/10). Sputum culture was positive when performed (8 cases). Diagnosis was made or confirmed by bronchoscopy (bronchoaspirate or protected specimen brush) in 5 patients. Germs isolated were: Nocardia asteroides (8/10), Nocardia farcinica (1/10), Nocardia otitidiscaviarum (1/10). Cotrimoxazole was the most used empirical treatment (6/10).

Anti-TNFα-induced TB-IRIS is often treated empirically with corticosteroids; however, the evidence of the effectiveness of corticosteroids is lacking and the management can be a challenge. A 32-year-old man on long-term infliximab therapy for Crohn disease visited a clinic complaining of persistent fever and cough that had started 1 week previously. His most recent infliximab injection had been administered 14 days before the visit. A chest X-ray revealed a left pleural effusion, and he was admitted to a local hospital. A chest computed tomography (CT) scan revealed miliary pulmonary nodules; acid-fast bacilli were found in a sputum smear and a urine sediment sample; and polymerase chain reaction confirmed the presence of Mycobacterium tuberculosis in both his sputum and the pleural effusion. He was diagnosed with miliary TB. Antituberculous therapy was started and he was transferred to our hospital for further management. His symptoms initially improved after the initiation of antituberculous therapy, but 2 weeks later, his symptoms recurred and shadows on chest X-ray worsened. A repeat chest CT scan revealed enlarged miliary pulmonary nodules, extensive ground-glass opacities, and an increased volume of his pleural effusion. This paradoxical exacerbation was diagnosed as TB-IRIS associated with infliximab. A moderate-dose of systemic corticosteroid was initiated [prednisolone 25 mg/day (0.5 mg/kg/day)]. After starting corticosteroid treatment, his radiological findings improved immediately, and his fever and cough disappeared within a few days.

Often presenting with very non-specific symptoms, this disease presents many challenges to the emergency medicine practitioner. A 47-year-old male with no pertinent medical history presented to the emergency department complaining of shortness of breath. He stated that his symptoms had been persistent for the last three weeks and were associated with malaise and fatigue. CT of the abdomen/pelvis with IV contrast revealed a 7-cm hypodensity of the spleen concerning for abscess versus infarct. He denied any trauma or IV drug use. Follow-up ultrasound was ordered, which characterized the hypodensity as a splenic abscess. An echocardiogram was recommended for possible IE, and cardiology was consulted. The transthoracic echocardiogram was performed on hospital day 2, which showed minimal mitral valve thickening with mild mitral regurgitation. The interventional radiology (IR) service was consulted for the splenic abscess in order to perform CT-guided drainage. An IR drain was successfully placed on hospital day 3. On the same day, blood cultures grew Klebsiella pneumoniae. On hospital day 5, that patient was transferred to the ICU for possible empyema formation with signs of respiratory distress. The patient underwent CT of the chest that showed the development of a left-sided effusion. The patient had also been persistently tachycardic and febrile, with high leukocytosis since admission and worsening respiratory status. Transesophageal echocardiogram (TEE) was scheduled but put on hold due to worsening respiratory status. Repeat TEE was scheduled five days later, which showed mitral regurgitation and increased size of the vegetation despite antibiotic therapy. Two days later, he was scheduled for mitral valve repair. When reviewing our case, the patient had both common and uncommon aspects of splenic abscess or IE. First, despite having respiratory symptoms for two weeks, the primary reason he came to the hospital was due to the new onset of fevers. He was febrile, tachycardic, and with significant leukocytosis. He continued to have fevers despite antibiotic therapy and IR drainage of the abscess. With no history of IV drug use history, negative transthoracic echocardiography, lack of immunocompromising condition, and blood cultures with gram-negative rods, IE became less likely of a diagnosis.  Establishing the diagnosis of IE proved to be exceptionally complicated, especially in the setting of a COVID-19 pandemic. The most notable challenge was having a high index of suspicion despite any risk factors. The patient was a previously healthy 47-year-old male with no medical problems. IE continues to be a clinical challenge for physicians, especially in the emergency department, due to the lack of diagnostic criteria such as positive blood cultures or vegetations visualized on echocardiographic studies. IE has a wide gamut of presentations with different levels of acuity. Diagnosis is more straightforward when patients present with obvious risk factors, but, in many cases, such as this one, those risk factors may be absent.

He had travelled to India 10 months previously and denied any exposure to tuberculosis (TB). He was an ex-smoker with a 20 pack history. Respiratory examination confirmed decreased air entry of the right lower lobe and stony dullness on percussion. His C reactive protein was 178 mg/L. A chest radiograph identified a moderate-sized right-sided pleural effusion and destruction of the lateral aspect of the right fifth rib, strongly suggestive of underlying malignancy. Further investigation with a CT of the thorax identified a focal lytic lesion in the right fifth rib, at its lateral aspect, with expansion of the rib observed. Ultrasound-guided pleural aspiration confirmed an exudative pleural effusion. Gram stain revealed no organisms or polymorphs. Four days post admission, the patient was transferred to the regional thoracic surgery unit and underwent video-assisted thoracic surgery, bronchoscopy and drainage of his empyema. His Mantoux tuberculin skin test and his TB Elispot were negative, suggesting that TB infection was unlikely. Culture confirmed no growth after 48 h incubation. Histology of his pleural biopsy identified multiple non-confluent necrotising granulomatous inflammation with very occasional acid-alcohol-fast bacilli-like organisms, highly suspicious for mycobacterial infection.

She was raised by an eccentric father, suspected of having pervasive developmental disorder, and a dominant mother. After graduating from high school, she worked as a clerk in a company for twenty years or so; however, a change in her work environment made her fall into a depressive state. Her worsening depression caused her impulsive resignation and disappearance for about four months. She spent the duration of her disappearance traveling the country, with no dissociative episodes. After returning, she received treatment for depression as an inpatient for about four months. During the first month of hospitalization, she mainly complained of a depressive mood and anxiety over the prognosis of her disorder, while she made scarcely any progress in introspection. In the second month, she gradually advanced with introspective work, but, as her introspection progressed, her depressive mood became aggravated. The therapist avoided intervention to modify her cognition, and told her the following: \"it is better not to persist in managing your depressive mood itself because curing depression does not mean resolving the superficial depressive mood, but to achieve a condition not directly influenced by mood.\" Then, at the beginning of the third month, she became aware of \"the presence of God\" and, at the same time, her depressive mood greatly improved. She extended her sympathy to her mother with her unfortunate life history, and expected her mother to change as she herself had experienced, but, disappointed by her mother, she experienced anxiety attacks and came to realize her own internal rage against significant persons in her life including her mother. After \"the Great being\" experience, she, who had formerly attended Christian church for a short time, started to read the Bible, but she still hesitated about committing herself to \"religious following.\" One day during the last month of hospitalization, as she prayed to God for healing when she read a part in the Bible about a woman suffering from a hemorrhage for twelve years who touched the hem of Jesus' garment and was healed immediately (Matthew 9:20-22 and Luke 8:43-48), the patient suddenly experienced \"the salvation of God\" and realized what trust really meant. Through the experience, her clinical problems became totally cured, and the therapy concluded with her discharge from hospital. Several months later, she sent the therapist a letter including the following message: \"I am grateful to the Lord for salvation from anxiety and irritation, but to the therapist for helping me realize it.\" This clinical course can be understood based on the patient's clinical problems (e.g., despair, anxiety, and depression), arising from the breakdown of her efforts to maintain stability by founding her psychological base on her feelings of omnipotence, avoiding facing her internal negative psychological factors (e.g., rage), and these were automatically resolved when her psychological base was switched to the transcendent level through \"the Great being\" experience and \"the salvation of God.\" Such a sudden, marked improvement resembles what Miller and C'de Baca reported as \"quantum change,\" of which the characteristics are vividness, surprise, benevolence, and permanence. The therapist paid attention to maintain a constant psychological distance from the patient, not persisting in modifying her cognition, with the transcendent level being the basis for the entire therapy. This stance of the therapist itself was considered to prompt her transcendence and bring about her eventual cure. This clinical course seemed to be highly suggestive of a psychotherapeutic mechanism, indicating the close relationship between the transcendent level and basic trust." }, { "id": "wiki20220301en047_76", "title": "Mixed affective state", "score": 0.01061923583662714, "content": "psychic acceleration, however, (as seen in mania or hypomania) the thoughts move in a rapid progression, with many themes, rather than a singular one, being touched upon.

She denied any known precipitant for her depression.She is a ninth grade honors student in the gifted program at a local high school and is described as a talented musician, playing multiple musical instruments as well as soccer and basketball. She has good family support, was sociable, and had several close friends. She denied any history of trauma and denied ever using recreational drugs or other mood-altering substances.At this visit, she reported feeling \"sad and anxious.\" Family history was significant for maternal depression, which persisted through her teens and twenties. Her older sister had been diagnosed with Social Anxiety Disorder. Beth reported anhedonia, fatigue and irritable mood, lack of motivation, impaired concentration, and anxiety related to failing grades.You decide to begin medication because of the severity of her symptoms, and 1 week after starting fluoxetine 10 mg, she reportedly overdosed on an unknown quantity of acetaminophen. Within a few days of switching to escitalopram (due to persistent gastrointestinal complaints while taking fluoxetine), she developed homicidal ideation. She reported feeling grandiose, empowered, invincible, elated, and \"crazy,\" although she never demonstrated or endorsed psychotic symptoms. She became fixated upon the idea that she could kill someone and \"get away with it.\" At the time she tried to suffocate a peer with her hands, she was described as having \"a glazed over look in her eyes.\" Moods were now described as alternating between depressed and elated, with mood shifts occurring every few days. These symptoms did not improve after the antidepressant medication was discontinued.Subsequently, patient was admitted for acute psychiatric care, at which time she was described as depressed, but with an \"expansive and irritable\" mood, and with obsessive suicidal ideation. She had developed a plan to hang herself in the home. She started to believe that her mother was trying to give her \"poison.\" She reported panic attacks and said that she wanted to be in the hospital where she could feel \"safe.\" She claimed to have an \"entity inside of her body who was a bully\" and who was \"taking over her body\" and stated that he put her hand over her peer's mouth, as she watched.Psychological testing included the Minnesota Multiphasic Personality Inventory-Adolescent, showed significant paranoia, bizarre mentation, and poor reality testing. Along with interview and observation, it was determined that patient met criteria for the DSM-IV-TR clinical diagnosis of Other Specified Bipolar Disorder, with psychotic features.Aripiprazole was initiated at a dosage of 2 mg; however, moods were still described as fluctuating between extremes every few hours. It was discontinued after reaching 5 mg due to affective blunting. Risperidone 0.5 mg twice daily helped patient to feel and act \"more like herself\"; however, she continued to report significant depression. The addition of lamotrigine 25 mg daily, in addition to individual Dialectical Behavior Therapy, finally led to improvement of mood and a gradual return of her normal baseline, with reportedly stable emotional, social, and academic functioning.The patient's mother remained convinced that this adolescent's mood instability was caused by underlying hormonal problems so you refer her to endocrinology. Beth developed puberty at age 8, with menses occurring on average of twice yearly. She was found to have elevated free testosterone level of 8.6 (reference range, 1.2-7.5). She was of normal weight (body mass index = 21.85 kg/m) and did not manifest acne, male pattern hair thinning, or hirsutism. Thyroid functions, 17-OH progesterone, follicle-stimulating hormone/luteinizing hormone, and estradiol were within normal limits. Prolactin elevation (46.3) was assumed to be due to Risperidone. Patient refused ovarian ultrasound.After starting oral contraceptives to establish monthly menses, patient's emotional and behavioral symptoms continue to remain stable. After Beth decided on her own to discontinue psychotropic medications, she continued for 17 months following her initial visit to remain free of neuropsychiatric symptoms.Now that her symptoms seem resolved; you wonder what the medical diagnosis for Beth was? You wonder if \"hormones\" may have caused or contributed to her psychiatric presentation." }, { "id": "wiki20220301en167_27986", "title": "Tell Her About It", "score": 0.009900990099009901, "content": "\"Tell Her About It\" is a 1983 hit song written and performed by Billy Joel, from the album An Innocent Man.

These paresthesias involve an irresistible urge to move the limb, which provides temporary relief but at the expense of sleep and quality of life. The pathophysiology of RLS has been related to dopaminergic pathway dysfunction, thereby aligning it closely with depression from both pathophysiologic and treatment perspectives. Certain antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), may induce or exacerbate RLS. We describe the case of a 34-year-old woman with no history of RLS who came to the emergency department with acute decompensated heart failure. After 7 days of hospitalization, she was waitlisted to receive a heart transplant. Her mood became depressed, and she requested a psychiatric consultation; escitalopram 10 mg at bedtime was started. Within 2 days of starting therapy, she developed very severe (determined by a score based on an RLS symptom rating scale) RLS symptoms, warranting the discontinuation of escitalopram. Within 2 days of stopping therapy, her RLS symptoms improved considerably (rated as mild). One week later, the patient was rechallenged with a lower dose of escitalopram, and her very severe RLS symptoms reappeared. Within 2 days of stopping escitalopram, her RLS symptoms again improved, with complete resolution 1 week later. Using the Naranjo adverse drug reaction probability scale, which assesses the probability of a drug causing an adverse event, the patient's score was 9, indicating a definite adverse drug reaction. Although published case reports have linked fluoxetine, sertraline, citalopram, paroxetine, and mirtazapine to RLS, this is the first report, to our knowledge, of escitalopram as a cause of RLS.

Depression is known to be a complication of brain tumours and may sometimes be seen after the presentation of neurological symptoms linked to brain tumours, and sometimes after tumor treatment (Oğuz et al. 2005, Litofsky et al. 2004, Moise and Madhusoodanan 2006, Oreskovic M et al. 2007, Rooney A et al. 2010). The dorsolateral prefrontal, orbitofrontal and medial frontal circuits constitute the three subcortical neuronal circuits in the frontal cortex. The dorsolateral prefrontal circuit is associated with planning and operational functions and lesions on it may give rise to apathy, abulia, perseveration, personality changes and planning disorder. Lesions involving the orbitofrontal circuit, which is associated with response suppression and disinhibition, may involve emotional lability and memory problems. Whereas lesions affecting the right orbitofrontal circuit give rise to elevated mood, lesions on the left orbitofrontal circuit lead to depressed mood. In cases with medial frontal circuit involvement, akinetic mutism may result from lesions in the superior medial region and anteroretrograde amnesia and confabulation are observed with lesions in the inferior medial region (Tosun et al. 2016, Chirchiglia 2018). A diagnosis of psychiatric disorder may be given during the first examination of patieants with primary brain tumours, especially if localized in the frontal lobe. Thorough history taking and physical examination are necessary for early diagnosis. The case reported here concerns a 29-year-old university graduate female patient, living with her partner and children, who consulted the clinic with complaints of tendency to frequent crying, anhedonia, having difficulty with speech fluency, forgetfulness and distractedness that had presented suddenly, 2 months previously, without any causative stressor. In her mental status examination, she appeared having normal self-care with appearance at her actual age. She was fully conscious and oriented, not willing to cooperate with the interview, had distinct difficulty in maintaining attention and with fluency of speech. Her mood was depressive. She described loss of appetite, fatigue and energy loss. Her difficulty in paying attention was pronounced. She did not have a history of psychotropic medication use or family history of psychiatric disease. She did not smoke or use alcohol or substance. After evaluating the clinical interview, a preliminary diagnosis of major depressive disorder was considered on the basis of the DSM-5 criteria. Routine blood tests were requested. Given the continuation of her complaints, the difficulty with fluent speech and the increase in tendency to sleep at the first week follow up, cranial MRI was planned. The MRI results showed on the right, in the frontal lobe a multilocular mass with precallosal extension, undiscernable margins with the right lateral aspect of the corpus callosum genu and dispersed cystic-necrotic areas with T2 signal series. The dimensions of the mass were nearly 5 x 3 cm causing a 1-cm right-to-left shift of the midline (Figure 1) DEPRESSION AS THE FIRST SYMPTOM OF FRONTAL LOBE GRADE 2 MALIGNANT GLIOMA 2 Türk Psikiyatri Dergisi 2 Turkish Journal of Psychiatry Letter to the Editor 143 144 The patient was referred for surgery with the preliminary diagnosis of high-grade glial tumour. Pathology results identified a grade 2 glioma. It was learned that radiotherapy sessions were begun after surgery. The patient did not have any symptoms of psychopathology during the 2 monthly psychiatric interviews made after surgery. Brain tumours generally indicate their presence with headache, seizures and other neurological symptoms and very rarely with depression as seen in the case of our patient. It should be kept in mind that atypical psychiatric symptoms may have an underlying organic lesion and subtle neurological symptoms should be investigated in detail. A recent meta-analysis on 37 observational studies determined a 21.7% prevalence of depression in a total of 4518 patients with intracranial tumours. Comorbidity of depression with brain tumor was demonstrated to worsen the quality of life, increase suicidal risk and lower the chance of survival (Huang et al. 2017). The possibility of psychiatric symptoms being the clinical clues for brain cancer was noted and the necessity of neuroimaging tests in cases of recent-onset psychosis or mood disorder symptoms, atypical personality changes and anorexia without body dysmorphic disorder was emphasized (Madhusoodanan et al. 2015). Loss of interest, tendency to frequent weeping, introversion and anhedonia were the sole complaints in the case discussed here. The increase in psychomotor retardation and slowing down of movements at the very first weekly control follow up necessitated neuroimaging. Despite the reports in the literature on the frequent association of unpreventable excessive behavior, disinhibition and irritability with right frontal injury and lesions (Okumuş and Hocaoğlu 2018), depression was the dominant symptom in the case presented here. There are differences between primary major depression and depression presenting with underlying somatic diseases which is known to occur at later ages (Rouchell et al. 2002). However, our patient was aged 29 years. Also, cases of depression due to somatic disease are less associated with family history of depression and suicidal ideation and attempts, while cognitive symptoms come to the foreground during mental status examination. (Sertöz and Mete 2004, Rouchell et al. 2002). Our patient did not have suicidal ideation or attempts, or a family history of depression. In apathy, which may be explained as emotional blunting, indifference or detachment from the external world, targeted behavior is also reduced next to the lack of emotional expression. The individual discussed here was learned not to sit at the table or change the television channel unless reminded to do so. When the reason was asked, she could not think of one. The reduction in emotional expression accompanies reduced insight, abulia and lack of empathy (Sözeri Varma et al. 2019). In depression, apathy is defined as 'sorrowless depression'. Our patient cried but had very blunted mimics and gestures. She explained that she could not help weeping even at times when she did not feel internally distressed. The seriousness of apathy, as a symptom difficult to differentiate from depression, is still not understood.

Comparison of 45 individuals with depression due to aging and 43 healthy individuals showed apathy to be associated with fronto-limbic gray and white matter abnormalities which continued after antidepressant treatment. The structural anomalies of the posterior subgenual cingulate gyrus and the uncinate fasciculus were discussed (Yuen 2014). The case discussed here is presented to emphasize the importance of brain imaging methods and detailed investigation of atypical symptoms for diagnostic approaches to psychiatric disorders. Especially, complaints at young age of depression with psychomotor retardation, reduced fluency of speech and sudden onset withdrawal without stressors should be a warning of secondary depression.

VPD is also used as an augmentation strategy in refractory depression. Despite chemical similarity between VPA and VPD, the pharmacokinetics of the 2 drugs in humans are quite distinct. We report a case of a patient, suffering from a bipolar treatment resistant depression, who dramatically improved after substituting VPD to VPA in association with fluoxetine. Mme X, 68 years old, has been hospitalized in March 2001 for the treatment of a resistant depression (TRD). She was suffering from removal of small intestine with chronic diarrhoea after a suicidal attempt two years ago. She had a bipolar disorder treated with VPD (1,200 mg/d) since 1 year. She presented a major depressive episode according to DSM IV with various symptoms like depressed mood, hypersomnia and difficulty initiating sleep, diminished ability to concentrate and to think, markedly diminished pleasure in all activities and major anxiety. Mme X fulfilled TRD diagnosis after resistance to two adequate antidepressants trials from different classes (clomipramine 175 mg/day and venlafaxine 300 mg/day). The antidepressant treatment (venlafaxine) was interrupted and she has been receiving a SSRI (fluoxetine 20 mg/day) for 4 weeks. After four weeks, she had a partial remission with persistent sleep problems, mood lability and anxiety. The VPA blood concentration was very low: 27 mg/L (normal range: 50 to 100 mg/L) in spite of a high dosage: 1,200 mg/day. Pharmacokinetic analysis of VPD shown that VPD transformation to VPA usually done in the intestine, was reduced because of the removal of hail intestine. We substituted VPD by VPA. Valproate blood concentration returned to normal range, induced dramatic improvement of depression within three days. VPD is an amide derivative of valproic acid (valproate), biotransformed by hydrolysis to its corresponding valproic acid. VPD is a prodrug of VPA. VPD is absorbed after transformation in gastro-intestinal mucous membrane. The adequate dosage of VPD (Depamide, 300 mg) is 4 to 6 tablets in acute manic phases, 2 to 4 tablets in long term treatment, 1 to 3 tablets in depressive episode. The biodisponibility of VPD is around 100% 75 and 90% of VPD is linked with protein albumin. The daily dosage determined the blood concentration of the active form (VPA), but this relation isn't linear. The optimal blood concentration of VPA (Depakine) ranges between 50 and 100 mg/L. the free form of VPA is influenced by protein disorders such as of hypoalbuminemia and by presence of fat acids in food. This case report demonstrates at a clinical level that VPD and VPA are not equivalent for treating bipolar depression. This case also suggests that a deep investigation of the pharmacokinetic of psychotropic drugs can help clinicians to resolve clinical problems of treatment of depression." }, { "id": "pubmed23n1011_4825", "title": "[If a patient has never experienced depression, should we tell him he has bipolar disorder?

It is characterized by episodic changes in mood and energy/activity levels that are increased during mania/hypomania or decreased during depression. Recurrent mania (RM) is a mood disorder, which would be defined by at least two manic/hypomanic without depressive episodes. Despite a rich body of clinical descriptions, RM is still not integrated into the latest editions of disease classifications and continues to be subsumed under BD in clinical practice. We conducted a systematic review of the literature to pool data about RM prevalence within BD groups, identify differences between RM and BD and develop reliable knowledge about specificities of RM. Furthermore, we sought to identify the methodological bias inherent to RM studies. Relevant publications were identified by a systematic search of PubMed, Embase, ScienceDirect and PsychInfo databases according to PRISMA criteria, with no limitation of date. The following MESH terms were used: (mania OR manic) AND (unipolar) NOT (depress*) OR (\"unipolar mania\" OR \"unipolar manic\" NOT \"depress*\"). Twenty-three (23) of 186identified studies met eligibility criteria for our systematic review. The total sample included 1118RM subjects among 4796BD subjects. The weighted mean of RM prevalence was 23.2%. Compared to BD, RM was characterized by a predominance of men, an earlier age at illness onset, less rapid cycles and seasonal variations, longer manic episodes, less specific clinical features (suicide attempts, anxious disorders, catatonic symptoms, irritability, hyperactivity, racing thoughts), less family history of depression, more addictive comorbidities and worse response to lithium prophylaxis (P&lt;0.05). However, many studies failed to replicate these significant differences. RM studies were mainly retrospective. The major bias of RM studies were the lack of consensus on the defining criteria for RM and the risk of unreported depressive episodes, both in charts that were reviewed in retrospective studies and in prospective studies with insufficient follow-up duration. Although the literature on RM remains sparse, many authors agree that RM should be distinguished from BD. RM would concern almost 1 in 4 BD patients. Furthermore, several clinical variables could differentiate this mood disease from BD and may orient the specific therapeutic choice. However, clinical criteria are still not reliable enough to make a diagnosis of RM. Further studies are required to replicate the results of existing studies and to adjust for the effect of methodological biases." }, { "id": "pubmed23n0491_13877", "title": "[Psychiatric manifestations of vitamin B12 deficiency: a case report].", "score": 0.009433962264150943, "content": "Psychiatric manifestations are frequently associated with pernicious anemia including depression, mania, psychosis, dementia.

The cerebral scan and EEG were normal. Fundic biopsy, realized by fibroscopy, revealed fundic atrophia and intestinal metaplasia compatible with Biermers' disease. The iron deficiency exploration concluded diet deficiency. Mme V. appeared euphoric, her speech was very rapid with play on words and overactivity. This hypomania state totally disappeared 3 days after. Six Months after her hospitalisation, she presented an hypothyroidism (TSH=3,780; T3=1,35; T4=1,08). A thyroid hormones replacement was started and she continued to receive Monthly B12 replacement. Discussion - This case report illustrates psychiatric manifestations of Biermers' disease. The clinical arguments in favour are: white woman, more than 60 Years old, no history of psychiatric problems, atypical symptoms (confusional state with psychiatric symptoms), fluctuation of symptoms (severe depression with confusional state, delusion of persecution and Capgras' syndrome; delusion with lability of mood and hypomania), dramatic improvement after 9 days of vitamin B12 replacement therapy. The biological arguments are: anemia, vitamin B12 deficiency, normal folate level, atrophia and fundic metaplasia, positive antibodies to parietal cells in the serum, association between Biermers' disease and autoimmune disease (Haschimoto thyroidite). Psychiatric manifestations can occur in the presence of low serum B12 levels but in the absence of the other well recognized neurological and haematological abnormalities of pernicious anemia. Mental or psychological changes may precede haematological signs by Months or Years. They can be the initial symptoms or the only ones. Verbank et al. described the case of a patient with vitamin B12 deficiency in whom hypomania, paranoia and depression had been successively presented during a period of 5 Years before anemia have been developed. The case of Mme V. is similar in the succession of severe depression with delusion of persecution and Capgras' syndrome, delusion with lability of mood and hypomania, during a period of two Months. This report seems to be the first one of a sequence of several psychiatric states with pernicious anemia during a period of two Months with normocytosis anemia. To illustrate this illness we reviewed the literature regarding psychopathology associated with B12 deficiency. The most common psychiatric symptoms were depression, mania, psychotic symptoms, cognitive impairment and obsessive compulsive disorder. The neuropsychiatric severity by vitamin B12 deficiency and the therapeutic efficacy depends on the duration of signs and symptoms. Conclusion - We recommend consideration of B12 deficiency and serum B12 determinations in all the patients with organic mental disorders, atypical psychiatric symptoms and fluctuation of symptomatology. B12 levels should be evaluated with treatment resistant depressive disorders, dementia, psychosis or risk factors for malnutrition such as alcoholism or advancing age associated with neurological symptoms, anemia, malabsorption, gastrointestinal surgery, parasite infestation or strict vegetarian diet. In first intention, B12 deficiency should be researched by serum B12 determination (normal 200-950 pg/ml). Studies of methylmalonic acid and homocysteine showed that they are very sensitive functional indicators of cobalamin status especially when other evidence of cobalamin (B12) deficiency was equivocal. Measurement of methylmalonic acid (normal 73-271 nmol/l) and homocysteine (normal 5,4-13,9 micromol/l) should not replace the measurement of serum cobalamin." }, { "id": "wiki20220301en023_41908", "title": "Matthew Good", "score": 0.009433962264150943, "content": "The following summer, Good planned to spend several months in Europe to write a book.

We report 3 patients with obsessive compulsive disorder (OCD), without diagnosis and treatment, examined in a specialized memory consultation. They always had OCD with cognitive checking. Diagnosis of transient global amnesia and temporal complex seizure were discussed in 2 cases. Psychometric impairment only was observed in first free recall of a verbal memory task and was no specific. Behavioural during testing seemed to be very important to analyse. First, a 49-year-old man consulted because he had stereotyped transient amnesia lasted one minute, 2 or 3 times a week, since 6 months. He was a teacher. Transient amnesia always occurred during lessons. Suddenly he didn't know where he was or what he was speaking about. Episodes lasted one minute. After them, he had no confusion and no difficulty in concentration but intense anxiety. In an another hand, when he was in his car, after lessons, he could forget where he was during some minutes. CT scan and EEG were normal. Neuropsychological tests only objectived impairment in first free recall of Grober and Buschke's words. Patient explained that he could not prevent to check responses. He told us checking obsessive compulsive disorder during since long time ago. We discussed clear differences which existed between seizure and ruminations or preoccupations. Secondly, a 55-year-old woman was afraid of her memory performances. She was medical secretary and had no problem in her work but she would like a memory consultation to reassure herself. She was neither depressed nor anxious. She presented curious production in fluency task. She had to produce as many animals's names as possible: she could say 35 names which was an excellent performance but only in alphabetic order! Neuropsychological tests objectived impairment in her first free recall of Grober and Buschke's words. She tried in her first free recall to remember words in alphabetic order. She explained how she was bound to range everything in alphabetic order! She had a lot of rituals. She thought that she had an obsessive compulsive disorder but never consulted about this. The observation illustrated suspiscions about memory operations which could be observed in patients group with obsessive compulsive disorders. Finally, a 62-year-old man told us that he had presented a transient global amnesia during 4 hours. He had an important appointment and was upset about that. He didn't go to it and wandered in his flat. He always asked the same questions and forgot everything. He had no neurological deficit. He was anxious, sad and cried several times. He perfectly remembered the episod and thought that he had a panic attack! Verbal memory tests only objectived difficulties in his first free recall of Grober and Buschke words as the two others patients. He had a story of obsessive compulsive disorder with checking and rituals. In this observation, we discussed clear differences which existed between panic attacks and global transient amnesia. We analyzed patterns of neuropsychological performances which illustrated clinical features of obsessive compulsive disorder. These three patients impaired in their first free recall of verbal memory task. It is not a specific result. We observed during psychometric evaluation, strategic processing which impaired episodic memory: patients tried to check their performances. Memory complaints only were observed in checking obsessive compulsive disorder. It is a difficulty or a doubt about memory capacities. Difficulties could be due to particular cognitive processes who pertubate normal memory capacities." }, { "id": "wiki20220301en075_55574", "title": "Synchestra", "score": 0.009345794392523364, "content": "At the end of a whirlwind year, Townsend began working on Strapping Young Lad's fourth album, Alien, in March 2004.

Cooper, when talking of patients suffering from panic disorders, states that analysts must distinguish between psychologic efforts to cope with miscarried brain function and the psychologic efforts to cope with disturbances of the intrapsychic world. This is also true of patients who have affective disorders. For instance, patients who suffer from untreated affective disorder often speak of their experience of themselves as being out of control. They complain that they can never predict the stability of their emotional states. This aspect of their illness must be conceptualized not as reflecting faltering defensive operations and inadequate compromise formation but as the reaction of an otherwise healthy personality to the experience of being intermittently overwhelmed by biologically generated mood states. Cooper also states that biologic illnesses must be regarded as having influences that are both developmental and ongoing. The psychoendocrine work of Puig-Antic demonstrates the existence of endogenous depression in latency age children and Carlson and Kashani's recent clinical observations in preschool children support the notion that this illness can arise during periods of development. For such patients, the normal developmental tasks of childhood and adolescence may be severely compromised. For instance, extreme mood fluctuations of inexplicable origin may serve as a major disruption in the consolidation of a healthy sense of object constancy. Before closing, I would like to briefly mention two examples of the difficulties encountered when attempting to medicate and analyze the same patient. Ostow mentions patients who may attempt to use what he refers to as the \"drug cure\" to reinforce their resistance to psychotherapy. The analyst must be ever alert for this. An example occurred during my analysis of a 35-year-old novelist who had entered treatment for writer's block. She had been on medication for a number of years, had a strong family history of depression, and had relapses each time the medication had been discontinued or decreased. During the eighth month of analysis she reported that she had an interesting experience. She had forgotten to take her evening medication, something extremely unusual for her. She knew that antidepressants suppressed rapid-eye-movement sleep and that stopping tricyclics was often associated with vivid dreams and nightmares. Thus, she thought that the nightmare she experienced that night, something to do with being beaten up, could be explained pharmacologically.(ABSTRACT TRUNCATED AT 400 WORDS)" }, { "id": "pubmed23n0895_1203", "title": "A 9-Year-Old Girl With Persistent Obsessive and Compulsive Behaviors in a Primary Care Pediatric Practice.", "score": 0.009259259259259259, "content": "Chloe is a 9-year-old gal whose mother made an initial visit to a new pediatrician for concerns about her behavior.

A randomized, single-blind study was performed to evaluate the effects of the combination of high-dose furosemide and small-volume hypertonic saline solution (HSS) infusion in the treatment of refractory New York Heart Association (NYHA) class IV CHF and a normosodic diet during follow-up. Materials and Methods One hundred seven patients (39 women and 68 men, age range 65-90 years) with refractory CHF (NYHA class IV) of different etiologies, who were unresponsive to high oral doses of furosemide, angiotensin-converting enzyme inhibitors, digitalis, and nitrates, were enrolled. Inclusion criteria included an ejection fraction (EF) &lt;35%, serum creatinine level &lt;2 mg/dL, blood urea nitrogen level &lt; or =60 mg/dL, reduced urinary volume, and low natriuresis. The patients were randomized in 2 groups (single-blind). Patients in group 1 (20 women and 33 men) received an intravenous (IV) infusion of furosemide (500-1000 mg) plus HSS (150 mL of 1.4%-4.6% NACl) twice a day in 30 minutes. Patients in group 2 (19 women and 35 men) received an IV bolus of furosemide (500-1000 mg) twice a day, without HSS, during a period lasting 6 to 12 days. Both groups received IV KCl (20-40 mEq) to prevent hypokalemia. At study entry, all patients underwent a physical examination and measurement of body weight (BW), blood pressure (BP), and heart rate (HR), an evaluation of signs of CHF, and measurement of control levels of serum Na, K, Cl, bicarbonate, albumin, uric acid, creatinine, urea, and glycemia daily during hospitalization, and measurements of the daily output of urine for Na, K, and Cl. A chest radiograph, electrocardiogram, and echocardiogram were obtained at study entry, during hospitalization, and at the time of discharge from the hospital. During the treatment and after discharge, the daily dietary Na intake was 120 mmol in group 1 versus 80 mmol in group 2, with a fluid intake of 1000 mL daily in both groups. An assessment of BW and 24-hour urinary volume, serum, and urinary laboratory parameters were performed daily until patients reached a compensated state, when IV furosemide was replaced with oral administration (250-500 mg/d). After discharge from the hospital, patients were observed as outpatients weekly for the first 3 months and, subsequently, once a month. The groups were similar in age, sex, EF, risk factors, treatment, and etiology of CHF. All patients showed a clinical improvement. Ten patients in both groups had hyponatremia at entry. A significant increase in daily diuresis and natriuresis was observed in both groups, but it was more significant in the group receiving HSS (P &lt;.05). The serum Na level increased in group 1 and decreased in group 2 (P &lt;.05). The serum K level was decreased in both groups (P &lt;.05). BW was reduced in both groups (P &lt;.05). Group 2 had an increase in serum creatinine level. Serum uric acid levels increased in both groups. BP values decreased and HR was corrected to normal values in both groups.

The mechanism of action of sildenafil depends on activation of the nitric oxide (NO)-cGMP pathway during sexual stimulation, which results in corpus cavernosal smooth muscle relaxation and penile erection. Endogenously derived NO is also involved in blood pressure regulation through its effect on basal vascular tone, which is mediated by cGMP levels. Organic nitrates and NO donors exert their therapeutic effects on blood pressure and vascular smooth muscle by the same mechanism as endogenous NO. Since both sildenafil and organic nitrates exert their pharmacologic effects via increases in cGMP concentrations, a double-blind, placebo-controlled, crossover study was undertaken to investigate the effects of sildenafil coadministered with glyceryl trinitrate on blood pressure and heart rate in healthy male subjects. The hemodynamic effects of sildenafil were also evaluated in a second placebo-controlled crossover study in men with hypertension who were taking the calcium antagonist amlodipine, which has a mechanism of action that does not involve the cGMP pathway. In the first crossover study, subjects were treated with oral sildenafil (25 mg, 3 times a day for 4 days) or placebo and then challenged on day 4 with a 40-minute, stepwise, intravenous infusion of glyceryl trinitrate (0.5 mg/mL in 5% dextrose at an initial infusion rate of 2.5 microg/min and doubling every 5 minutes to a maximum rate of 40 microg/min) 1 hour after taking sildenafil or placebo. On day 5, subjects received a sublingual glyceryl trinitrate tablet (500 microg) 1 hour after taking 25 mg of sildenafil or placebo.

When a sublingual glyceryl trinitrate tablet was administered on day 5, a 4-fold greater decrease in systolic blood pressure was observed for the subjects during the sildenafil treatment period than during the placebo treatment period. The changes in heart rate were negligible during both glyceryl trinitrate challenges. In conclusion, sildenafil potentiated the hypotensive effects of glyceryl trinitrate, an organic nitrate. Thus, sildenafil administration to patients who are using organic nitrates, either regularly and/or intermittently, in any form is contraindicated. In the second crossover study, men with hypertension, who were taking 5 or 10 mg/day of amlodipine, received a single oral dose of 100 mg sildenafil or placebo. Coadministration of sildenafil did not significantly affect the pharmacokinetics of amlodipine.

On day 2, plasma was withdrawn from the stored fetal blood until the hematocrit was approximately 70%, and the packed red blood cells were returned to the fetus intravenously over 10 minutes. Each fetus received either furosemide (2 mg/kg) or control saline solution intravenously at time zero and again at 5 minutes. The order of experiments was randomly determined for each animal. Hemorrhage resulted in a similar decrease in fetal hematocrit in the two groups. The mean +/- SEM fetal hematocrit before hemorrhage was 38 +/- 3% in the furosemide group (n = 8) and 36 +/- 2% in the control group (n = 8).

Incomplete suppression of the SNS may contribute to the residual mortality during optimal ACE inhibitor therapy in CHF. Carvedilol, a mixed alpha and beta-blocker with antioxidant properties, and other pure beta-adrenoceptor blockers reduce morbidity and mortality in Caucasians with CHF. However, beta-blocker monotherapy is of poor efficacy in Blacks with essential hypertension or in the treatment of glaucoma. The efficacy of beta-blockers in the treatment of African Americans with congestive heart failure is a controversial issue with conflicting findings. The aims of the present study were to examine and compare the cardiovascular, autonomic, and clinical effects of additional alpha-1, or beta-1 blockade in ACE-inhibitor treated Black patients with moderate to severe CHF. Twenty-eight Nigerian patients with chronic CHF stabilized on digoxin and diuretics, were randomized to 3 groups of similar demographics according to a single blind, parallel group design.

Two-way repeated measures ANOVA, and a one-way ANOVA were used in data analysis. The 3 treatments caused significant (P&lt;.001 ANOVA) and similar improvements for the NYHA class (-1.0 to -1.6), and increased the 6-minute distance covered (+130 m to +205 m). Although no treatment differences were observed, a trend suggesting a greater improvement with enalapril + atenolol became apparent. By the fourth week, the sympathoplegic treatments, enalapril + atenolol, and enalapril + prazosin, caused significant reductions in the pressure rate product (-3726 +/- 1885 mm Hg x beats/min; -3498 +/- 396 mm Hg beats/min, respectively), (compared to enalapril alone (-1349 +/- 894 mm Hg x beats/min) (P&lt;.001 ANOVA). During the Valsalva maneuver, the phase IV bradycardia were significantly greater after treatment with enalapril + atenolol (944 +/- 66 msec) or with enalapril + prazosin (825 +/- 48 msec), compared to enalapril alone (760 +/- 45 msec) (P&lt;.001 ANOVA). The phase II Valsalva tachycardia were similar between treatments. The respiratory sinus arrhythmia ratio increased significantly (P&lt;.005 ANOVA) and equally on all treatments. However, the pressor and chronotropic responses to forearm isometric handgrip increased significantly on the enalapril + prazosin combination (P&lt;.02), compared to the other treatments. Our findings demonstrated not only the safety of providing additional therapy with alpha-1 or beta-1 receptor blockade concurrent with ACE inhibition in Blacks with CHF, but also the resultant improvement in exercise tolerance and NYHA class. Compared to using ACE inhibition alone, the combined therapies caused a marked reduction in the pressure rate product, an index of myocardial oxygen consumption, and a greater enhancement of cardiac parasympathetic activity. Selective beta-1 blockade caused a greater enhancement of central baroreceptor vagal activity compared to alpha-1 blockade. Conversely, the pressor and chronotropic abnormalities during forearm isometric handgrip in CHF, were normalized by alpha-1, but not beta-1, blockade. Thus, the combined reflex cardiac vagal augmentation following selective beta-1 blockade, and the hemodynamic effects of alpha-1 antagonism with concurrent ACE inhibition, may be of major therapeutic and prognostic benefit in Blacks with non-ischemic (hypertensive) CHF stabilized on digoxin and diuretics." }, { "id": "pubmed23n0074_6371", "title": "Hypertension in the elderly: a study of a combination of atenolol, hydrochlorothiazide and amiloride hydrochloride.", "score": 0.008849557522123894, "content": "The anti-hypertensive effects of atenolol (Tenormin) 50 mg, a potassium-sparing diuretic (half-strength Moduretic) comprising hydrochlorothiazide 25 mg plus 2.5 mg amiloride hydrochloride, and the 'free' combination of atenolol and diuretic were compared in elderly hypertensive patients aged 60-79 years.

The examination revealed two lymphadenopathies, one in each groin, 1 cm in diameter, soft, mobile, non-painful. There are no skin lesions on the lower limbs, anus or perineum. Which test do you consider essential?

White cell count was 21.2 x 109/L; lymphocytes were 13.05 x 109/L (1.00 - 4.00). Therefore, computerised tomography (CT) of chest and abdomen was performed. Thrombus was present in pulmonary arteries bilaterally involving the lobar and segmental branches. Enlarged lymph nodes were seen in axillae, chest, abdomen and inguinal regions.

(2) When full blood count showed lymphocytosis (comprising &gt; 50% of white blood cells) with atypical morphology, lymphocyte surface markers, Paul Bunnell test, and Epstein Barr virus serology should be performed. These tests would have led to a diagnosis of infectious mononucleosis, and abdominal imaging studies could have been avoided.

Without treatment, it goes through the following stages: primary, secondary, latent, and tertiary (1). The clinical picture of secondary syphilis is very variable (2,3). We present two rare cases of secondary syphilis, one with nodular lesions initially considered to be lymphoma and second with periostitis, which was initially interpreted as an osteoma. To date, only 15 cases with nodular lesions and 10 cases with periostitis in secondary syphilis have been reported in the literature. The first patient was a 59 year old man who presented in a private practice with nodular lesions on the face and axillary and inguinal folds (Figure 1, a, b). The initial diagnostic consideration was lymphoma. A biopsy specimen was taken, and the histopathological features revealed epidermal hyperplasia with papillomatosis, minimal spongiosis with many neutrophils and with a marked inflammatory infiltrate in dermis, consisting of lymphocytes, plasma cells, and neutrophils; the diagnosis of interfaced dermatitis was established (Figure 1, d, e). After one month, the patient presented to our clinic with numerous nodular lesions, some of them painful, located on the trunk and intertriginous folds, including the intergluteal cleft - the lesions in this area being suggestive of condylomata lata (Figure 1, c). The diagnosis of secondary syphilis was taken into consideration, and screening serum tests were performed and found reactive: a Venereal Diseases Research Laboratory (VDRL) titer of 1:64 and Treponema pallidum Hemaglutination Assay (TPHA) titer of 1:80. Hepatitis and anti-human immunodeficiency virus (HIV) antibodies serology was negative. The biopsy was repeated and showed the same histopathological changes. In addition, Warthin-Starry staining was performed, revealing the presence of some spiral micro-organisms in the dermis corresponding to Treponema pallidum (Figure 1, f). A diagnosis of secondary syphilis was established, and the patient was treated with benzathine penicillin G 2.4 million units by intramuscular injection once a week for 2 consecutive weeks. The skin lesions regressed within 1 month, and serological tests showed a VDRL titer of 1:8 3 months after treatment. The second patient was a homosexual male, 35 years old, diagnosed with HIV infection, stage B2. He presented with bone pain in the calves and forearms, with insidious onset. He also presented with an associated erythematous maculo-papular rash on the trunk and limbs and generalized lymphadenopathy (Figure 2, a, b). The tibial crest and radius were sensitive to palpation. A right leg radiography was performed, raising suspicion of osteoid osteoma. The CT scan excluded the diagnosis of osteoma; taking into account the epidemiological context, the diagnosis of syphilis was suspected. The diagnosis was confirmed by leg ultrasound examination (2D US) which showed thickening of the compact tibial bone associated with subperiosteal destructive and proliferative changes (Figure 2, c, d) and by serology for syphilis: the VDRL titer was 1:32 and the TPHA titer was 1:80. The patient was treated with benzathine penicillin 2.4 million units, once a week, for 2 consecutive weeks, with clinical improvement. Syphilis continues to be a serious public health problem worldwide, even if it is a controllable disease due to diagnostic tests and effective and accessible treatment. According to the World Health Organization in 2008, the estimated number of new cases of sexually transmitted diseases in adults with syphilis is 10.6 million cases (4). The cases presented in this paper were characterized by unusual manifestations, requiring good collaboration between the dermatologist and other specialties. In the first case, the diagnosis of secondary syphilis was confirmed by positive serological, clinical, and histopathological findings. The main differential diagnosis of nodular syphilis includes lymphoma, sarcoidosis, Kaposi's sarcoma, atypical mycobacteriosis, deep fungal infections, leprosy, tuberculosis, leishmaniasis, and lymphomatoid papulosis (5). Another important differential diagnosis is between secondary and tertiary syphilis, especially when ulcerating nodules are present. Tertiary syphilis is characterized by unilateral, deep ulcerating nodules with necrotizing granulomas (6). Bone involvement during syphilis is mainly represented by polyarthritis, synovitis, osteitis, and periostitis (7,8). Syphilitic periostitis is characterized by localized or diffuse pain, particularly during the night, which is relieved by movement. The skull, the shoulder girdle, and the long bones are the most common sites of involvement (9). In conclusion, we presented two different cases of secondary syphilis that contribute to the clinical experience of rare cases presented in the literature, raising the awareness of dermatologists and other specialists about less specific clinical aspects of syphilis." }, { "id": "InternalMed_Harrison_10874", "title": "InternalMed_Harrison", "score": 0.009523809523809525, "content": "adenopathy that is sometimes mistaken for malignancy; syphilis, LGV, HSV infection, and chancroid involving the anus can produce inguinal adenopathy because anal lymphatics drain to inguinal lymph nodes." }, { "id": "wiki20220301en302_4978", "title": "Cervical lymphadenopathy", "score": 0.009433962264150943, "content": "Cervical lymphadenopathy is a sign or a symptom, not a diagnosis.

Approximately 20% of the world's population suffers from herpes zoster at least once in a lifetime, with 10% to 20% having ophthalmic involvement. Treatment of the acute disease with oral antivirals may reduce the incidence and severity of complications but does not reliably prevent PHN or postherpetic itch (PHI).

There were no language restrictions. Two review authors independently selected trials, evaluated the risk of bias in included trials, and extracted and analysed data. We did not conduct a meta-analysis, as only one study was included. We assessed the certainty of the evidence for the selected outcomes using the GRADE approach. One study fulfilled the inclusion criteria. In this multicentre, randomised double-masked study carried out in France, 110 immunocompetent people with herpes zoster ophthalmicus, diagnosed within 72 hours of skin eruption, were treated, with 56 participants allocated to the valacyclovir group and 54 to the acyclovir group.

Similarly, there was uncertainty as to the comparative effects of these two treatments on post-herpetic pain, and side effects (vomiting, eyelid or facial edema, disseminated zoster). Due to concerns about imprecision (small number of events and large confidence intervals) and study limitations, the certainty of evidence using the GRADE approach was rated as low to very low for the use of valacyclovir compared to acyclovir. This review included data from only one study, which had methodological limitations.

The prevalence of PHA in patients who present in specialized hypertension centers is approx. 10 %. Besides patients with the classical symptoms known as \"Conn-Trias\" (hypertension, hypokalemia, metabolic alkalosis), the more frequent normokalemic patients with PHA also show a worse outcome compared to patients with essential hypertension. Identifying these patients is an important task in the evaluation of hypertension since targeted treatment options are available. Screening for PHA using the Aldosterone-Renin-Ratio (ARR) should be performed in patients with hypokalemic, severe or resistant hypertension. In addition, young patients with early onset of severe hypertension and/or positive family history should be screened. A positive screening result should be followed by a confirmatory test. The saline infusion test is the preferred clinical test for confirming a suspected PHA since it is accessible and time efficient. Other confirmatory tests are not used on a regular basis. After any confirmatory test, CT- or MRI-imaging and adrenal vein sampling (AVS) is used in order to differentiate between a unilateral adenoma, a bilateral hyperplasia or another cause of PHA. CT or MRI usually cannot discriminate smaller tumors form hyperplasia. Therefore AVS is used to detect lateralization of autonomous aldosterone production. Lateralization of aldosterone production indicates a unilateral adenoma. In these cases, laparoscopic adrenalectomy is the therapeutic option of choice with a hypertension cure rate of up to 60 %. If no lateralization is detectable, bilateral hyperplasia as the underlying cause of PHA is likely. Pharmacological inhibition of the mineralocorticoid receptor is the preferred treatment option in these cases.

It is now recognized that the APA is just one of the seven subtypes of primary aldosteronism. APA and bilateral idiopathic hyperaldosteronism (IHA) are the most common subtypes of primary aldosteronism. Although most clinicians had thought primary aldosteronism to be a rare form of hypertension for more than three decades, it is now recognized to be the most common form of secondary hypertension. Using the plasma aldosterone to plasma renin activity ratio as a case-finding test, followed by aldosterone suppression confirmatory testing, has resulted in much higher prevalence estimates of 5-13% of all patients with hypertension. In addition, there has been a new recognition of the aldosterone-specific cardiovascular morbidity and mortality associated with aldosterone excess. Although thought to be daunting and complex in the past, the diagnostic approach to primary aldosteronism is straightforward and can be considered in three phases: case-finding tests, confirmatory tests and subtype evaluation tests. Patients with hypertension and hypokalaemia (regardless of presumed cause), treatment-resistant hypertension (three antihypertensive drugs and poor control), severe hypertension (&gt;or= 160 mmHg systolic or &gt;or= 100 mmHg diastolic), hypertension and an incidental adrenal mass, onset of hypertension at a young age or patients being evaluated for other forms of secondary hypertension should undergo screening for primary aldosteronism. In patients with suspected primary aldosteronism, screening can be accomplished by measuring a morning (preferably between 0800 and 1000 h) ambulatory paired random plasma aldosterone concentration (PAC) and plasma renin activity (PRA). An increased PAC:PRA ratio is not diagnostic by itself, and primary aldosteronism must be confirmed by demonstrating inappropriate aldosterone secretion. Aldosterone suppression testing can be performed with orally administered sodium chloride and measurement of urinary aldosterone or with intravenous sodium chloride loading and measurement of PAC. Unilateral adrenalectomy in patients with APA or unilateral adrenal hyperplasia results in normalization of hypokalaemia in all these patients; hypertension is improved in all and is cured in approximately 30-60% of them.

Growing evidence suggests that aldosterone could contribute to structural kidney damage, arterial injury and hemodynamic disorder. At the same time, patients with PA exhibit glomerular hyperfiltration and glomerular vascular hypertension, leading to the misinterpretation of renal function in PA patients as subtle kidney damage may be masked by the glomerular hyperfiltration before treatment. After a unilateral adrenalectomy, glomerular hyperfiltration by aldosterone excess is resolved and renal damage can be unmasked. In conclusion, kidney function deterioration after adrenalectomy can be detected in some patients with PA.

Our primary hypothesis was that in low-renin patients with normal plasma K+ and aldosterone, a thiazide diuretic, bendroflumethiazide, would be as effective as spironolactone in overcoming the Na+ retention and lowering blood pressure. Secondary objectives were to compare the dose response for each diuretic and to evaluate amiloride as an alternative to spironolactone.

In hypertensive patients with a low plasma renin but normal K+, bendroflumethiazide 5 mg was as effective as spironolactone 100 mg in lowering blood pressure, despite patients being selected for a previous large fall in blood pressure on spironolactone.

We report a 35-year-old woman who in the third trimester of pregnancy was found to have a large adrenal mass on routine obstetric ultrasound. On referral to our unit, persistent hypertension and long-standing hypokalaemia was noted, despite good compliance with multiple antihypertensives. Ten years earlier, she had hypertension noted in pregnancy which had persisted after delivery. A MRI scan confirmed the presence of a 12 cm adrenal mass and biochemistry revealed high levels of DOC and low/normal renin, aldosterone and dehydroepiandrosterone, with normal catecholamine levels. The patient was treated with antihypertensives until obstetric delivery, following which she underwent an adrenalectomy. Histology confirmed a large adrenal cortical neoplasm of uncertain malignant potential. Postoperatively, blood pressure and serum potassium normalised, and the antihypertensive medication was stopped. Over 10 years of follow-up, she remains asymptomatic with normal DOC measurements. This case should alert clinicians to the possibility of a diagnosis of a DOC-producing adrenal tumours in patients with adrenal nodules and apparent mineralocorticoid hypertension in the presence of low or normal levels of aldosterone. The associated diagnostic and management challenges are discussed. Learning points: Hypermineralocorticoidism is characterised by hypertension, volume expansion and hypokalaemic alkalosis and is most commonly due to overproduction of aldosterone. However, excess of other mineralocorticoid products, such as DOC, lead to the same syndrome but with normal or low aldosterone levels. The differential diagnosis of resistant hypertension with low renin and low/normal aldosterone includes congenital adrenal hyperplasia, syndrome of apparent mineralocorticoid excess, Cushing's syndrome, Liddle's syndrome and 11-deoxycorticosterone-producing tumours. DOC is one intermediate product in the mineralocorticoid synthesis with weaker activity than aldosterone. However, marked DOC excess seen in 11-β hydroxylase or 17-α hydroxylase deficiencies in DOC-producing adrenocortical tumours or in patients taking 11-β hydroxylase inhibitors, may cause mineralocorticoid hypertension. Excessive production of DOC in adrenocortical tumours has been attributed to reduced activity of the enzymes 11-β hydroxylase and 17-α hydroxylase and increased activity of 21-α hydroxylase. The diagnosis of DOC-producing adrenal tumours is challenging because of its rarity and poor availability of DOC laboratory assays." }, { "id": "wiki20220301en086_36538", "title": "Bartter syndrome", "score": 0.009349931823413787, "content": "Bartter syndrome consists of low levels of potassium in the blood, alkalosis, normal to low blood pressures, and elevated plasma renin and aldosterone.

We report a case of a 55-year-old man with a 10-year history of hypertension in whom functional hormonal studies were indicative of PA. Because adrenal venus sampling was not available at our hospital, the investigation was conducted with a computed tomography (CT) scan and a scan with 131-iodocholesterol (NP-59) which both revealed a left adrenal adenoma. The tumor was excised laparoscopically without any complications and the histological findings confirmed the diagnosis of an aldosterone-producing adenoma. Blood pressure remained normal despite the discontinuation of antihypertensive drugs, further supporting that the adrenal tumor was indeed the cause of high blood pressure. Unfortunately, blood pressure began to rise again 2 months later, and laboratory findings indicated the presence of PA once again. Spironolactone was instituted and blood pressure significantly improved and was finally controlled by the addition of amlodipine. We report this case to underline the difficulties in the discrimination between adenoma and hyperplasia in everyday clinical practice. Although the CT and scintigraphic findings strongly pointed toward an adenoma, the fact that PA re-appeared shortly after the operation, indicated that the underlying cause of the PA was hyperplasia and not adenoma after all." } ] } } }

Several conditions may cause atypical clinical aspects, including human immunodeficiency virus (HIV) co-infection. Besides the clinical features, co-infections may completely alter syphilis serological tests, causing interpretative difficulties and diagnostic delays. Aim of the work is to describe the difficulties encountered during the diagnostic evaluation of atypical skin manifestations and of the serology for syphilis of an HIV-infected patient who had contracted it several times. In 2020, a 52-year old HIV-positive bisexual male patient was admitted to our department with a 4-month history of moderately itchy cutaneous lesions localized at his neck, trunk and arms. In 2013, the patient presented with a classic syphilitic roseola of the trunk and a secondary syphilis was diagnosed, with increased levels of rapid plasma reagin (RPR), Treponema pallidum hemagglutination assay (TPHA), anti-Treponema pallidum IgM and IgG Index. A second episode occurred in 2018, as a primary syphilis with multiple ulcerative lesions of the penis, and increased levels of RPR, IgG and IgM. In 2019, a further episode of secondary syphilis was treated with Doxycycline. In 2020, erythematous and papular lesions with vesicular components and urticarial erythema multiforme (EM)-like lesions were present at the neck, trunk and arms. Serological tests and Nucleic Acid Amplification Test (NAAT) for Treponema Pallidum were performed, as well as a cutaneous biopsy with histological and immunohistochemical evaluation of one lesion. NAAT was negative for T. pallidum. Serological test results were discordant with a new syphilis infection, showing only increased levels of RPR and anti-Treponema IgG. The cutaneous biopsy revealed a non specific histological pattern, while the immunohistochemical evaluation with anti-spirochetal antibodies was mandatory for the diagnosis of recent syphilis, showing clusters of rod-shaped elements, some of which with spiral form, focally present at the epidermis and adnexal structures. Nowadays, syphilis may present with atypical clinical and serological features.

We highlight an interesting case of a 45-year-old man on whose diagnosis of secondary syphilis was based on the presence of unusual oral lesions, consisting of a well delimited, raised, nonhomogeneous, and corrugated white plaque on the right buccal mucosa which mimicked, clinically and histologically, a \"leukoplakia-like\" plaque and several whitish oral mucous patches localized on the lower labial mucosa and the right lateral margin of the tongue. After the oral lesions, the patient developed a symmetric maculopapular cutaneous rash on the palms, soles, and the trunk of the body. Furthermore, during the anamnesis the patient stated an asymptomatic ulcerative lesion on the glans penis, which had appeared 7 months before the onset of the oral lesions and spontaneously disappeared after 2 weeks. The history of these genital and cutaneous lesions suggested performing serologic tests for syphilis, revealing strongly positive titers and leading us to making a diagnosis of secondary syphilis. This case is remarkable because it displays an unusual oral sign, associated with secondary syphilis; in fact, only occasionally does syphilis manifest itself with a \"leukoplakia-like\" plaque.

His visual acuity had been gradually declining over the past few months. He denied painless or painful ulcerating lesions on his penis, or scrotum, difficulty concentrating, dermatitis on the soles/palms, or difficulty with proprioception. Physical exam was notable for atrophic hyperpigmented polycyclic, annular plaques and patches along the hairline as well as several areas of confluent hyperpigmented polycyclic plaques and nodules on the patient's face, back, left arm, and right posterior leg. Fundoscopic exam revealed bilateral posterior uveitis and chorioretinitis. Evaluation of cerebrospinal fluid revealed a lymphocytic pleocytosis with a positive VDRL and FTA-ABS.

Within six hours of beginning the infusion, the patient had a documented temperature of 101.8°F, heart rate of 128 beats per minute, blood pressure 142/84, with generalized malaise and headache. Fever and tachycardia resolved over the next 12 hours, with weakness and headache resolving within 1-2 days. His symptom complex was consistent with the Jarisch-Herxheimer reaction. Histopathology of skin biopsy of the back showed perivascular inflammation and rare spirochetes, consistent with secondary syphilis. The patient completed 14 days of aqueous crystalline penicillin G and was discharged after receiving the first of three benzathine penicillin injections. The initial manifestations of syphilis in this patient were posterior uveitis and pruritic skin plaques. His diagnosis should be appropriately classified as secondary syphilis with concomitant symptomatic early neurosyphilis, requiring 14 days of aqueous crystalline penicillin G. This type of presentation is not specific to immunocompromised populations and must be considered even in the general population. Making the diagnosis of early neurosyphilis, regardless of stage, is critical, as it necessitates a longer duration of treatment.

Without antibiotic treatment syphilis lasts for several decades and may develop up to 4 different clinical stages. Usually, the disease begins with a distinct painless and indurated ulcer at the contact site: the primary chancre. An indolent regional lymph node swelling is usually associated with the syphilitic chancre. After spontaneous healing of the primary lesion and several weeks of latency, the clinical symptoms of secondary syphilis occur. Treponema pallidum bacteremia leads to common symptoms like fever and malaise, but also to a generalized lymphadenopathy, and a broad variety of lesions of the skin and mucosal membranes. Non-pruritic transient exanthems often involving palms and soles, condylomata lata, and a specific angina with mucous patches of the oral cavity are prominent signs. After several relapses, which are characterized by a decreasing intensity of clinical symptoms, secondary syphilis then resolves spontaneously. A second period of latency follows, lasting 3-12 years. Then the outcome of untreated syphilis becomes apparent: spontaneous healing by elimination/inactivation of the spirochetes (75%) or transition to tertiary syphilis (25%). Two kinds of granulomatous skin reactions are typical for tertiary syphilis: superficial nodular syphilids and gummas. The bones, as well as the cardiovascular and central nervous system, may also be involved.

Co-infection with human immunodeficiency virus (HIV) was present in four of them. Other risk factors discovered on history were unprotected sexual relations, multiple partners, homosexual relations, co-infection with another sexually transmitted disease (STD) or an occupational risk. Decreased visual acuity (VA) was present in all patients, with an average initial VA of 0.71 ± 0.81 LogMAR, i.e. 2/10. Involvement was bilateral in 38% (n=5) of cases.

If untreated, primary syphilis can progress to secondary syphilis, which has a characteristic rash and diverse systemic features. This report is of a case of secondary syphilis with mucocutaneous, articular, and pulmonary involvement. CASE REPORT A 74-year-old Moroccan man presented with an 8-week history of bilateral knee pain and swelling. On examination, he had bilateral knee effusions. Articular puncture brought an inflammatory fluid with a significant presence of white blood cells. Inflammatory markers were elevated. X-rays of both knees showed bilateral osteoarthritis with intra-articular calcification in the left knee. Nonsteroidal anti-inflammatory drugs and colchicine were prescribed, but were ineffective. A closer clinical examination of the patient revealed pigmented papules on the palms, soles, oral mucosa, trunk, and genitals. Treponema pallidum hemagglutination assay and Venereal Disease Research Laboratory results were positive in the blood (titers 1: 32) and joint fluid. A computed tomography scan of the chest revealed a focal opacity in the lateral basal segment of the right lung. The diagnosis of secondary syphilis with mucocutaneous, articular, and pulmonary involvement was made. The evolution was favorable after a single intramuscular injection of benzathine-penicillin.

In addition to causing hypoxemia, atelectasis and acute lung injury can lead to right ventricular failure through an acute increase in pulmonary vascular resistance. Mechanical ventilation is often applied, accompanied with recruitment maneuvers and positive end-expiratory pressure in order to recruit alveoli and reverse atelectasis, while preventing excessive alveolar damage. This strategy should lead to the reversal of the hypoxemic condition and the detrimental heart-lung interaction that may occur. However, as described in this case report, hemodynamic instability and intractable alveolar atelectasis sometimes do not respond to conventional ventilation strategies. We describe the case of a 21-year-old Caucasian man with severe chest trauma requiring surgical interventions, who developed refractory hypoxemia and overt right ventricular failure. After multiple failed attempts of recruitment using conventional ventilation, the patient was ventilated with high-frequency oscillatory ventilation. This mode of ventilation allowed the reversal of the hemodynamic effects of severe hypoxemia and of the acute cor pulmonale. We use this case report to describe the physiological advantages of high-frequency oscillatory ventilation in patients with chest trauma, and formulate the arguments to explain the positive effect observed in our patient. High-frequency oscillatory ventilation can be used in the context of a blunt chest trauma accompanied by severe hypoxemia due to atelectasis. The positive effect is due to its capacity to recruit the collapsed alveoli and, as a result, the relief of increased pulmonary vascular resistance and subsequently the reversal of acute cor pulmonale.

Flail chest injuries are mostly combined with lung injury (contusion, rupture, laceration) and subsequent pneumothorax or haemothorax. Early mechanical ventilation with internal pneumatic splinting is a conservative treatment for flail chest in patients with respiratory insufficiency. The surgical stabilisation of a flail chest is an effective method of treatment and is beneficial for selected patients. It shortens the duration of mechanical ventilation and thus reduces morbidity associated with prolonged ventilatory support. In addition, it decreases long-term pain and the inability of a flail chest to heal due to malunion, non-union or progressive collapse of the flail segment. Surgical stabilisation of a flail chest is indicated when the clinical examination shows progressive respiratory dysfunction confirmed by the results of multiple detector computer tomography (MDCT) of the thorax. Thirty-three consecutive patients who underwent surgical stabilisation of a flail chest at the Trauma Centre between 2010 and 2014 were retrospectively evaluated. This included patient demographics, chest injury extent, results of pre-operative chest imaging (MDCT), surgical stabilisation technique and post-operative outcome. In addition to providing a radiographic finding of respiratory failure, the result of MDCT chest examination was considered an important criterion for surgical intervention. Surgical stabilisation of the chest wall was performed at an interval ranging from 2 hours to 11 days after injury. Intra-thoracic procedures were indicated in patients with lung injury (pulmonary laceration). The surgical procedure was completed by chest tube placement. Surgical stabilisation was carried out using 3 to 8 plates for flail segment fixation involving 3 to 4 ribs. The duration of post- operative mechanical ventilation was 5 days on the average. It was longer in patients with associated injuries such as craniocerebral trauma or severe pulmonary contusion.

Data were retrospectively collected from all patients admitted with rib fractures from January 2016 to December 2016 to the Department of General Surgery, Khoo Teck Puat Hospital, Singapore. The outcomes identified were mortality, pain scores on injury day 1, 3, 5, and 7, injury severity score, duration of mechanical ventilation, worst partial pressure arterial oxygen/fraction of inspired oxygen (PaO<sub2</sub/FiO<sub2</sub) ratio, length of intensive care unit (ICU) stay, and pulmonary complications. Motor vehicle accident was the most common cause of rib fractures (63.1%, <in</i = 123). Patients with flail chest had more associated pneumothorax (53.8% vs. 35.2%) and lung contusions (53.8% vs. 30.2%) compared to those without flail chest and underwent more investigations such as inpatient-computed tomography scans (76.9% vs. 59.3%), interventions such as chest tube insertion (61.5% vs. 19.8%), and ICU admission (46.1 vs. 13.7%). Patients also had higher pain scores, used more analgesic modalities, and had increased inpatient mortality (30.8% vs. 4.4%). Flail chest is associated with higher morbidity and mortality. Proactive management from a multidisciplinary team such as identification of high-risk patients in particular patients with flail chest, early admission to critical care, and protocols including multimodal pain management, respiratory support, and rehabilitation should be instituted." }, { "id": "pubmed23n0124_13019", "title": "Determinants of outcome after pulmonary contusion.", "score": 0.009345794392523364, "content": "During the past 5 1/2 years, 86 patients were treated for pulmonary contusion resulting from blunt trauma.

The purpose of this retrospective study was to analyze the indications and outcomes of operative chest wall stabilization in defined groups of patients sustaining flail chest with and without pulmonary contusion. The hospital records of 405 patients with multiple trauma (Injury Severity Score &gt; 17) between 1988 and 1994 were reviewed. Forty-two patients sustained flail chest. Twenty of these underwent operative chest wall stabilization for the following indications: 1) flail chest with indication for thoracotomy due to intrathoracic injury (n = 6); 2) flail chest without pulmonary contusion (n = 9); 3) paradoxical movement of a chest wall segment in the weaning period from the respirator (n = 3); and 4) severe deformity of the chest wall (n = 2). For the purpose of analysis the patients were separated into groups: group 1: operative chest wall stabilization in flail chest without pulmonary contusion (n = 10); group 2: operative chest wall stabilization in flail chest with pulmonary contusion (n = 10); group 3: flail chest without pulmonary contusion and without chest wall stabilization (n = 18); group 4: flail chest with pulmonary contusion and without chest wall stabilization (n = 4). Data were coded for time of operation, duration of ventilatory support, and complications. There were no significant differences in age, severity of injury, and extent of injury between groups 1, 2, and 3 (p &lt; 0.42). Group 4 was excluded for statistical analysis because of the small number of patients. Patients in group 1 required a shorter ventilatory support time compared to patients in group 3 (6.5+/-7.0 versus 26.7+/-29.0 days) and group 2 (p &lt; 0.02).

One patient in group 1, three patients in group 2 and five patients in group 3 developed pneumonia with further disturbance of gas exchange. All patients in group 1 survived; deaths in group 2 were attributed to massive hemorrhage in two and septic multiorgan failure in one patient. Four patients in group 3 died of head injury, one of acute respiratory distress syndrome, one of severe hemorrhage, and one of multiple organ failure. In patients with flail chest and respiratory insufficiency without pulmonary contusion, operative chest wall stabilization permits early extubation.

Because of worsening clinical condition with onset of partial respiratory insufficiency and new loud systolic murmur at the left sternal edge, a transthoracic echocardiography was performed, which showed an apical ventricular septal defect. Surgery was performed immediately. The ventricular septal defect was successfully repaired using a Teflon felt patch and interrupted sutures with pledgets, and sealed with glue. At six months' follow up the patient was doing well. Ventricular septal defects after blunt chest trauma occur either because of heart compression between sternum and the spine or because of myocardial infarction. In the present case the ventricular septal defect appeared three days after the accident, probably secondary to a post-traumatic myocardial infarction.

This group (LK) developed significantly more cases of respiratory distress (ARDS). The disturbance of respiratory function seen initially was interpreted as a consequence of the direct mechanical impact, leading to the formation of interstitial fluid and hematoma. The frequent development of ARDS in the LK-group probably results from a pronounced activation of cellular and humoral mechanisms and therefore an enforced injury of the pulmonary capillary bed.

During a mean follow-up period of 3.7+/-1.4 years, 91 patients experienced an incident stroke event. Although a lower eGFR was associated with an increased stroke risk using a univariate model, statistical significance disappeared after adjusting for other risk factors including albuminuria. The HR (95% CI) was 0.75 (0.40-1.41, P=0.373), 0.99 (0.50-1.95, P=0.964) and 0.91 (0.36-2.28, P=0.844) for patients with eGFRs of 60-89, 30-59 and 15-29 ml min(-1) per 1.73 m(2), respectively, compared with patients with an eGFR &gt;or=90. Clinical albuminuria remained a significant risk factor for stroke, and the adjusted HR compared with normoalbuminuria was 2.40 (1.46-3.95, P=0.001).

However, it is currently unknown whether abnormalities in albumin excretion rate (AER) have a different renal prognostic value depending on the underlying renal structure. Aims of this study were: 1) to study the course of renal function in type 2 diabetic patients with altered AER; 2) to evaluate the relationship between the course of glomerular filtration rate (GFR) and renal structure; and 3) to evaluate the relationship between the course of GFR and baseline AER levels, metabolic control, and blood pressure levels during a follow-up period of 4 years. A total of 108 type 2 diabetic patients, 74 with microalbuminuria (MA) and 34 with proteinuria (P), were recruited into a prospective study that encompassed: 1) a baseline kidney biopsy with morphometric measurements of glomerular parameters; 2) intensified antihypertensive treatment for an average 4-year period (blood pressure target &lt;140/90 mmHg); and 3) determinations of GFR at baseline and every 6 months. Mean (+/- SD) GFR significantly decreased from baseline in both MA (-1.3+/-9.4 [95% CI -3.51 to +0.86], P &lt; 0.05) and P (-3.0+/-13.0 ml x min(-1) x 1.73 m(-2) per year [-7.71 to +1.61], P &lt; 0.01). However, the changes in GFR were quite heterogeneous. Thus, on the basis of percent GFR change per year from baseline (delta%GFR), both MA and P patients were defined as progressors or nonprogressors when they were below or above the median, respectively. Baseline parameters of glomerular structure had a strong influence on the course of GFR. Indeed, the odds ratios of being progressors significantly increased across the quartiles of baseline glomerular basement membrane (GBM) width and mesangial fractional volume [Vv(mes/glom)], being 2.71 and 2.85 higher, respectively, in the fourth quartile than in the first quartile (P &lt; 0.01 for both).

Baseline albumin excretion rate (AER) did not influence delta%GFR; in fact, the number of progressors did not increase across quartiles of baseline AER among either MA or P. Similarly, mean blood pressure levels during follow-up (and intensified antihypertensive therapy) did not affect the course of GFR: the number of progressors and nonprogressors did not change across quartiles of mean blood pressure. In contrast, HbA1c during follow-up had an impact on delta%GFR: the odds ratio for being a progressor increased across quartiles of HbA1c, particularly for the highest quartile (HbA1c &gt;9.0%). In conclusion, the course of renal function is heterogeneous in type 2 diabetic patients with microalbuminuria or proteinuria. In fact, a subset of patients has a rapid decline in GFR over a 4-year follow-up period; these patients have more advanced diabetic glomerulopathy and worse metabolic control than the remaining patients, whose GFR remains stable. These two cohorts are otherwise undistinguishable as regards the degree of AER at baseline and tight blood pressure control. Kidney biopsy has an important prognostic role in these patients.

Group B (a) was conversely treated with intensive insulin therapy to achieve a HbA1c value below 7.5% (3 daily injections of regular and 1 or 2 daily injections of intermediate acting insulin associated with metformin 500 mg twice daily in 64% of the patients). Group B (b) patients were only treated by metformin (850 mg thrice daily) to achieve a HbA1c value below 7.5%. HbA1c decreased below the 7.5% target value in Group B (a) (7.0 +/- 1.6%, p&lt;0.01 vs Period 1), but not in Group B (b) (8.0 +/- 1.6%, p&lt;0.05 vs Period 1) and in Group A (8.3 +/- 1.7%, n.s. vs Period 1).

GFR decay during Period 2 was similar to that observed during Period 1 in Group A (Period 1 vs Period 2: +1.21 +/- 0.71 vs +0.7 +/- 0.6 ml/min/1.73 ml/year, n.s.) and in Group B (b) (Period 1 vs Period 2: -4.4 +/- 0.71 vs -4.2 +/- 0.6 ml/min/1.73 m2/year, n.s.). Median AER did not significantly change in the fourth year of Period 2 , either in Group A or B (Group A vs B: 141 vs 152 microg/min, n.s.). In conclusion, our findings seem to suggest that amelioration of blood glucose control is attained both by insulin and metformin intensive treatment, but only insulin decreases and maintains HbA1c levels below 7.5%. These pattens of HbA1c appear to be a threshold value in order to significantly blunt GFR decay in a subgroup of Type 2 diabetic patients with typical diabetic glomerular lesions, who are less responsive to tight blood pressure control alone. Conversely, the cohort of patients with less severe diabetic glomerulopathy steadily show constant GFR patterns, despite similar abnormalities of albumin excretion rate, and HbA1c average values above 7.5%." }, { "id": "pubmed23n0297_3729", "title": "Glomerular hyperfiltration in the prediction of nephropathy in IDDM: a 10-year follow-up study.", "score": 0.009615384615384616, "content": "Glomerular hyperfiltration has been proposed as an independent risk factor for the development of diabetic nephropathy in patients with IDDM.

However, it is possible that some diabetic patients could first manifest reduced glomerular filtration rate (GFR) or hypertension. Relatively advanced diabetic renal lesions can be present in some diabetic patients with long-standing normoalbuminuria, and this might indicate increased risk of progression to microalbuminuria and then to overt diabetic nephropathy. The aim of this study was to identify a group of normoalbuminuric type 1 diabetic patients with low GFR and compare them with normoalbuminuric patients with normal GFR. Altogether, 105 normoalbuminuric type 1 diabetic patients with at least 10 years of diabetes duration that had a renal biopsy performed for research purposes were studied. Patients were divided according to GFR into groups with normal (&gt;/=90 ml x min(-1) x 1.73 m(-2)) or reduced (&lt;90 ml x min(-1) x 1.73 m(-2)) GFR. Clinical and renal structural parameters were compared between these two groups. Glomerular structural parameters were estimated by electron microscopic morphometry. The 23 patients with reduced GFR had more advanced diabetic glomerular lesions. The finding of reduced GFR was much more common among female patients, particularly if retinopathy and/or hypertension were also present. This report confirms that reduced GFR occurs among long-standing normoalbuminuric type 1 diabetic patients and is associated with more advanced diabetic glomerular lesions and, probably, with increased risk of progression. For these reasons, we suggest that regular measurements of GFR be performed in long-standing normoalbuminuric type 1 diabetic female diabetic patients, especially in those with retinopathy or hypertension." }, { "id": "pubmed23n0325_18925", "title": "[How I evaluate...diabetic nephropathy.

Therefore, the current study explored CY and ATG without buffy-coat cell transfusions in 39 patients with aplastic anemia given marrow transplants from HLA-identical family members (siblings in 38 cases, father in 1 case).

Nevertheless, AA still remains a potentially life threatening disease. Because response to treatment with ATG and cyclosporin is delayed for two to three months and sometimes longer, patients usually need intensive transfusional support and careful attention to infection prophylaxis and treatment, particularly fungal infection. It is important to adopt a careful transfusional policy at diagnosis, in particular to help prevent HLA alloimmunisation which results in refractoriness to platelet transfusions, and sensitisation to minor histocompatibility antigens which is thought to mediate graft rejection between HLA identical siblings. The indications for immunosuppressive therapy or HLA identical sibling BMT are fairly clear, but transplantation from volunteer unrelated donors remains a highly controversial and high risk procedure in patients with AA. The effects of haemopoietic growth factors in AA patients have been perhaps not surprisingly disappointing, and not without significant toxicity, with the exception of granulocyte colony stimulating factor (G-CSF) which is well tolerated clinically.

For those who lack such a matched donor, use of matched unrelated donors and family member donors who are mismatched for a single HLA antigen have been successful and appear to be the treatment of choice. Patients lacking either of these alternatives should receive antilymphocyte globulin, either alone or combined with cyclosporine as a first step. Although the success rate of marrow transplants in our series using mismatched family donors is similar to that following treatment with antilymphocyte globulin, several caveats must be kept in mind. First, the results reported with use of alternative donors must be confirmed with study of larger numbers of patients and longer follow-up. Second, the preparative regimen given prior to bone marrow transplantation destroys the patient's residual bone marrow, whereas antilymphocyte globulin cyclosporine A and androgens do not. The sequence of immunosuppression followed by transplantation with alternative donor marrow should produce greater long-term hematopoietic improvement. Unfortunately, when marrow transplant follows one or more courses of immunosuppressive therapy, nonengraftment is then a problem because of sensitization to blood cell antigens. It should also be kept in mind that studies done in children, especially in those younger than 6 years old, show that these patients respond better to transplantation than to treatment regimens not including marrow transplantation. Therefore, for the child with severe aplastic anemia, every effort should be made to identify a suitable bone marrow donor. Finally, we need to determine the specific components of the conditioning regimen and the constitution of the donor marrow necessary for engraftment and to minimize potential long-term complications, and there should be only a tolerable degree of graft-versus-host disease.

The patients were split into 2 groups: patients transplanted before 1989 (n = 24), and patients who had their BMT from 1989 onwards (n = 20). This was due to a change in the treatment policy, namely a reduction in the period between diagnosis and BMT, resulting in fewer blood transfusions as well as changes in the prophylaxis against graft-versus-host disease (GvHD) from 1989 onwards (combination therapy using methotrexate and cyclosporin). There was an increase in the 1-year actuarial survival rate from 67% in the period before 1989 to 90% thereafter. The incidence of GvHD has significantly decreased since the introduction, in 1989, of the combination therapy using methotrexate and cyclosporin, with only 1/20 patients suffering from acute GvHD versus 13/24 prior to 1989 (p = 0.002).

Next, pancytopenia developed following the rapid discontinuation of the immunosuppressive agent. Although neutrophils and platelets spontaneously recovered, anemia progressed. Based on severe erythroid hypoplasia in the bone marrow and the elevation of anti-ABO isohemagglutinin against donor-derived red blood cells, the patient was diagnosed with pure red cell aplasia (PRCA) following hematopoietic cell transplantation. Because complete chimerism was attained at the PRCA onset even for B cells, we decided to conservatively manage PRCA with only red blood cell transfusion.

Four factors were associated with lower survival: older age, use of Cy-TAI, any form of treatment prior to transplantation (either androgens or immunosuppressive therapy, [IST]), and grade II to IV acute graft-versus-host disease (GvHD). TAI was the sole factor associated with the occurrence of acute GvHD. The risk of cancers (15-year cumulative incidence, 10.9%) was associated with older age and with the use of cyclosporine as IST before transplantation.

In contrast to immunosuppressive therapy, allogeneic marrow transplantation results in cure of aplasia. Problems initially limiting the success of HLA-matched allogeneic marrow transplants included graft rejection and complications associated with acute and chronic GVHD. Infusion of donor buffy coat cells along with marrow or alternatively more intensive immunosuppressive regimens containing irradiation have substantially decreased the risk of rejection. However, buffy coat infusion increases the incidence of chronic GVHD and irradiation treatment adds to toxicity of the conditioning regimen as well as producing long-term complications. The incidence and severity of acute GVHD have been significantly decreased by the use of MTX/CSP as GVHD prophylaxis; however, this regimen has had no impact on the incidence of chronic GVHD.

Without treatment, ischemic tissue damage leads to irreversible necrosis. Treatment is emergency surgical decompression. The burned patient is usually not searchable and cannot always be readily examined because of bulky dressings; diagnosis of compartment syndrome is always hard to make. The pressure transducer used in central arterial catheters is easy available. We used it to measure pressure in muscular compartments. We measured compartment pressure three times at different depths in all cases of electrical burn, carbonization and deep circumferential burns with delayed escharotomy. We also took the pressure in the uninjured limb. The pressure assessment device was composed of a blood pressure transducer commonly used in arterial catheters for arterial pressure monitoring with three connecting branches. The first branch was connected to the 'arterial pressure exit' in the monitoring device. The second, an IV tube, was connected to one litre of physiological serum in a pressure bag inflated to 200 mmHg. The third, also an IV tube with a sterile extension cable, was directly connected to an 18G standard straight needle to be inserted in the tissues for which interstitial pressure had to be measured. In patients with thermal burns, we measured pressure before and after escharotomy. Threshold intracompartmental pressure was 35 mmHg. We carried out pressure assessment of all muscular compartments during and at the end of surgery. The pressure transducer provides a pressure value in all muscular compartments with a time of installation and measuring of less than 5 minutes. Sensitivity is measured at +/- 1 mmHg. Operation is simple, non-operator dependent, and accessible to medical and paramedic teams. The pressure transducer allows accurate diagnosis of early or established compartment syndrome. It requires no additional equipment and its application does not delay therapeutic management. Its use helps with fasciotomy decision, especially after escharotomy, guides the surgeon in the exploration of different compartments and verifies the effectiveness of surgery." }, { "id": "pubmed23n0536_5544", "title": "Revascularization in distal lesions of upper extremity arteries.", "score": 0.009900990099009901, "content": "A study was made of the course of ischemia and hemodynamic disorders in 53 patients with occlusion of the distal arterial system of the upper extremities.

These latter patients are treated in special rooms equipped for intensive therapy. Open and closed methods of treatment for burns used in addition to early excision are compared. The first aim is early skin cover for areas with skin loss preserving as much function as possible and achieving the best possible cosmetic result. Local therapy must be atraumatic to prevent extension of the skin lesion. Bacterial contamination must be prevented as far as possible by keeping the wound clean. Emergency treatment and the course of wound healing up to the third week after the injury using the appropriate dressings are described. Early excision until the fifth day after the accident should be used mainly for burns of the hand, deep second degree burns of up to 10% of the body surface, deep second degree burns over the joints and deep second degree burns of the neck. It must be admitted that the depth of the burn can only be definitely estimated between the seventh and tenth day after the accident. If no autografts are available homografts or grafts from animals are used. The age of the patient, associated injuries, associated diseases and the extent of the burn all play a role in determining the prognosis. Furthermore endogenous bacterial infections, absorption of local therapeutic agents and the state of the surrounding skin do also influence the healing process. Finally the various local therapeutic agents like sulphamylon, silver sulphadiazine and betadine are discussed. A 0.05% solution of silver nitrate is also active against gram-negative infections.

Chronic progressive lesions permit enlargement of collateral blood supply which, for a time, minimizes the severity of symptoms. Milde degrees of arterial insufficiency (claudication) can be treated conservatively. Unreconstructed chronic critical ischemia predicts a poor outcome in terms of survival and limb salvage. The outlook with arterial reconstructive surgery is by far better. Arteriography ist the most reliable diagnostic test for occlusive lesions. It ist essential for the operative planning.

Follow-up for 1 to 36 months showed no abnormal renal function in 4 patients. <bConclusions:</b The early AKI in patients No. 1 and 4 was caused by rhabdomyolysis after severe burn complicated with myofascial compartment syndrome, while that of the other 2 cases were also related to hypovolemic shock and poor renal perfusion. The success rate of early AKI treatment in severely burned patients can be effectively improved by removing the causes of diseases at the same time of CRRT and actively treating burn wounds under the support of organ function and hemodynamic monitoring." }, { "id": "pubmed23n0994_16338", "title": "Does the new vascular management of acute limb ischemia have effective results with lower treatment costs.", "score": 0.009009009009009009, "content": "Aim To compare hospital costs of acute limb ischemia treatment in two periods of time and to show evidence of long-term repercussions on reducing costs during successful treatment. Methods Retrospective analysis of data obtained from 100 patients' medical history in the period 2000-2016 at the Clinic of Vascular Surgery Sarajevo: group A - 60 patients with acute limb ischemia in the period 2005-2016 and group B - 40 patients with acute limb ischemia (ALI) in the period 2000-2005. From 2000 to 2005 conservative treatment method was used, invasive diagnostic and surgical procedures were often delayed for a shorter or longer period of time. During the period from 2005 to 2016, the management model and safe practice included emergency diagnostic procedures, colour-Doppler, arteriography, emergency surgery (embolectomy by Fogharty and if necessary, vascular by-pass). Results Better health service for the patients with acute limb ischemia was offered in the period 2005-2016, which relied on proven medical treatment trends. The largest share of the total costs of each patient included costs of hospital bed with significant difference between the period 2005-2016 and 2000-2005, mean of 1398.71 KM and 2480.45KM, respectively (p&lt;0.0001), indicating rationalization of time that patients spend at the Vascular Clinic.

Though current American Burn Association guidelines recommend burn unit referral for burns involving the hands or major joints, many minor injuries are treated in the emergency department (ED) or outpatient setting. Despite the large number of burn patients managed by primary care providers, no large studies have been performed to assess effectiveness. A retrospective 5-year review of the epidemiology and outcomes associated with pediatric upper extremity burns treated at an urban ED was performed. Two hundred sixty-nine patients were identified. The mechanism of burn, percentage of total body surface area (%TBSA) affected, plastic surgery consultations (for wound management recommendations and additional treatment), complications, and surgical interventions were examined. Mechanisms of burn included direct contact (47%), scald (29%), flame (12%), electrical (10%), and friction or chemical (1.5%). Fifty percent of patients suffered from burns over less than 1% TBSA; close to 95% had burns on less than 5% TBSA. Seventy-five percent of patients had second-degree burns, 21% had first-degree burns, and 2% had third-degree burns. Forty patients (15%) had a plastic surgery consult. Seven patients (3%) required skin grafting. Complications occurred in five (2%) patients and included two cases of hypertrophic scarring; two patients with flexor contractures, one case of compartment syndrome requiring fasciotomy, and one late infection. These results suggest that although significant burns are usually cared for in specialized burn centers, the majority of childhood burns to the upper extremity are relatively minor and often treated in the primary care setting. Most patients had small areas of injury and healed without complications. Contact burns are an ever-increasing proportion of childhood burns and should be seemingly preventable. Education to parents and primary care physicians should be reemphasized. It appears that minor upper extremity burns treated by our urban ED staff are handled appropriately and result in favorable outcomes." }, { "id": "wiki20220301en059_66337", "title": "Dorsalis pedis artery", "score": 0.008849557522123894, "content": "The dorsalis pedis communicates with the plantar blood supply of the foot through the deep plantar artery.

The aim of this paper was to study the aetiology of lower limbs embolism and to detect factors influencing early and late results after the operative treatment. The study included 204 patients with 224 lower limbs embolism, treated surgically at the Institute of Cardiovascular Diseases of the Clinical Centre of Serbia in Belgrade in the period between 1993 and 1997. There were 107 (52.2%) female and 97 (47.8%) male patients. Thirty two (14.3%) patients were younger than 50 years, 64 (28.6%) were between 51 and 65, 101 (45.1%) between 66-75, while 27 patients (12.1%), were older than 75. Twenty (8.9%) patients were admitted less than 6 hours before the operation, 79 (33.3%) between 6 and 24 hours, and 125 (55.8%) more than 24 hours before the operation (Table 1). One hundred (53.6%) patients had motor and 133 (59.4%) sensor paralysis on admission. Table 2 shows arterial localization of the lower limbs embolism. The popliteal artery was involved in most cases. During the operation transfemoral arterial approach was used in 132 (58.9%) cases, while transpopliteal in 92 (41.1%) cases. Fourteen cases required bypass surgery, 43 fasciotomy, 2 intraoperative streptokinase and 4 intraoperative angiography. All patients were controlled using physical and CW Doppler ultrasonographic examinations immediately after the operation, and then one, six and 12 months, as well as every year. In 173 (84.4%) patients cardiac causes of embolism were found, in 8 (3.9%) noncardiac, while in 8 (3.9%) the cause could not be established. Of all cardiac causes absolute arrhythmia was most frequent. Table 3 and Table 4 show the aetiology of the lower limb embolism. The early amputation rate was 23 (10.3%) cases, while limb salvage was recorded in 174 (77.7%) patients. Of all saved limbs complete recovery was noted in 162 (72.4%) cases and peroneal nerve paresis in 12 (5.3%) cases. The early postoperative mortality rate was 27 (12.0%).

Of the total number of patients in 87 (56.5%) cases a late control examination was carried out. Forty nine (31.8%) patients died before the late control, while 18 (11.7%) did not come to control examination. Late recidivation of embolism was found in 3 cases.

Training on escharotomy indications, technique and pitfalls is essential, as escharotomy is both an infrequent and high-risk procedure in civilian and military medical environments, including low-resource settings. Therefore, we aimed to validate an educational strategy that combines video-based instruction with a low-cost, low-fidelity simulation model for teaching burn escharotomy. Pre-hospital and hospital-based medical personnel, with varying degrees of burn care-related experience, participated in a one-hour training session. The first part of the training consisted of video-based instruction that described the indications, preparation, steps, pitfalls and complications associated with escharotomy. The second part of the training consisted of a supervised, hands-on simulation with a previously described low-cost, low-fidelity escharotomy model. Participants were then offered two psychometrically validated instruments to assess their learning experience. 40 participants were grouped according to prior burn care and surgical experience: attending surgeons (6), surgery and emergency medicine residents and fellows (26), medical students (5), and pre-hospital personnel (3). On two psychometrically validated questionnaires, participants at both the attending and trainee levels overwhelmingly confirmed that our educational strategy met best educational practices on the criteria of active learning, collaboration, diverse ways of learning, and high expectations; they also highly rated their satisfaction with and self-confidence under this learning strategy. An educational strategy that combines video-based instruction and a low-cost, low-fidelity escharotomy simulation model was successfully demonstrated with participants across a broad range of prior burn care experience levels. This strategy is easily reproducible and broadly applicable to increase the knowledge and confidence of medical personnel before they are called to perform escharotomy.

During the tensilon test, the patient's breathing difficulties in the supine position improved, and therefore his postural hypoxemia was thought to have resulted from diaphragmatic muscle weakness as a result of MG. MG respiratory failure is typically of the acute fulminating type and is considered to be a critical condition. However, it should be noted that there are cases, such as the present one, in which MG presents as postural hypoxemia." }, { "id": "pubmed23n0302_5864", "title": "[Ipsilateral pneumothorax in one-lung respiration.

This occurred in a 63-year-old patient with chronic obstructive airway disease who was scheduled for urgent repair of a descending thoracic aortic aneurysm. Anaesthesia and surgery were uneventful until aortic cross-clamping release. The common presentation of increased intrathoracic extrapleural pressure owing to a pneumothorax in patients with mechanically ventilated lungs is a rapid decrease in oxygen saturation, followed or paralleled by haemodynamic deterioration. Although the above presentation could be seen in this case, the diagnosis of a tension pneumothorax was delayed twice. First, symptoms were initially obscured by haemodynamic changes resulting from a head-down tilt and aortic declamping. Second, since the lack of consolidation after aortic declamping focused attention on the airway problems, complications resulting from the use of a DLT were primarily considered. In particular, since breathing sounds were detectable initially, malposition or torsion of the DLT had to be excluded by fibre-optic bronchoscopy, which involved a further delay. Finally, two observations led to the diagnosis of a right-sided tension pneumothorax: (1) bullae of the contralateral lung, detected during thoracotomy; (2) the finding that ventilation of both lungs and the left lung subsequently increased arterial (SaO2) and mixed venous oxygen saturation (SvO2) and the circulatory status, but ventilation of the right lung caused a deterioration. Chest radiography and insertion of a chest tube with drainage of air, thereafter, validated our hypothesis. The time course of oxygen desaturation during OLV and tension pneumothorax was as severe as expected; the time course of haemodynamic deterioration, however, appeared quicker and had more impact than expected. Assuming that mediastinal deviation was not hindered by contralateral intrathoracic pressure during thoracotomy, we believed that circulation should be depressed later or to a lesser extent in patients with an intraoperative pneumothorax. Yet, during thoracotomy, decrease in cardiac filling and output during tension pneumothorax in OLV obviously results primarily from the immovability of the mediastinum owing to mediastinal fixation and is at least as decisive as the contralateral intrathoracic pressure in closed-chest patients. In summary, a tension pneumothorax during one-lung ventilation and thoracotomy is a rare, but disastrous complication during the use of a DLT, which has not, to our knowledge, been reported previously. We recommend that tension pneumothorax be added to the list of complications and problems during OLV by the use of a DLT, especially in patients with structural lung diseases." }, { "id": "wiki20220301en548_4827", "title": "Respiratory compromise", "score": 0.009637188208616781, "content": "Respiratory compromise describes a deterioration in respiratory function with a high likelihood of rapid progression to respiratory failure and death.

The following conclusions were derived from this study. In normal subjects, downward motion of the IVS exhibited three patterns; namely, P1, between the onset of electrical depolarization and the onset of the second heart sound; P2, between the onset of the second heart sound and the E point of the anterior mitral leaflet; and P3, between the E point of the anterior mitral leaflet and the end of the left ventricular rapid filling phase, during each cardiac cycle. The systolic IVS pattern (P1) of atrial septal defect was classified as follows: Normal type: nearly normal posterior motion during ventricular systole, Flat type: flat motion during ventricular systole, Paradoxical (early systolic) type: anterior motion during the first half of ventricular systole, followed by normal posterior motion, Paradoxical (pansystolic) type: anterior motion during ventricular systole. In atrial septal defect, the right ventricular dimension was markedly increased in the flat and paradoxical (pansystolic) types compared with those of the normal and paradoxical (early systolic) types. Marked downward IVS motion (P2) was observed in cor pulmonale with paradoxical pulse, pulmonary hypertension, Ebstein's anomaly, pulmonic insufficiency, atrial septal defect, funnel chest, tricuspid insufficiency and constrictive pericarditis. In cor pulmonale with paradoxical pulse, the deep downward motion (P2) was observed more distinctly during inspiration compared to expiration, and right ventricular inflow velocity pattern was characterized by an apparent increase in peak flow in velocity of the diastolic rapid filling wave during inspiration. Two interesting findings were a deep \"y\" trough of the jugular pulse tracing and prominent P2 in funnel chest. Therefore, it was likely that exaggerated P2 seemed to be direct evidence of a marked increase in right ventricular rapid filling in the presence of normal or decreased left ventricular rapid filling. The augmented septal dip of P3 was observed in cases with the third heart sound as in normal subjects, and those with mitral insufficiency, and ventricular septal defect, constrictive pericarditis and mitral stenosis.

Auscultation of the heart helps to differentiate between the various causes of valvular lesions causing pulmonary edema. Auscultation typically reveals an S3 gallop in volume overload states, which may be associated with accentuation of the pulmonic component of S2. Several different types of murmurs can be heard depending on the cause of the valvular lesion. Mitral stenosis produces a low-pitched, rumbling diastolic murmur associated with an opening snap at the apex, which becomes accentuated on expiration and produces loud S1. Mitral regurgitation produces a blowing, high-pitched pan-systolic murmur best heard at the apex, radiating to the left axilla and accentuating on expiration, producing soft S1. Aortic stenosis produces a harsh crescendo-decrescendo ejection systolic murmur at the aortic area, increasing on expiration, usually radiating towards the right side of the neck. Aortic regurgitation produces a high-pitched blowing early diastolic murmur best heard in the aortic area, greatest during expiration." } ] } } }

Side effects did not require withdrawal of methotrexate. CRP level decreased faster than ERS: a 70% decrease of CRP by week 12 was recorded more frequently than that of ESR. Slow dynamics of the number of swollen joints compared with CRP may be due to the low cumulative dose of methotrexate. Duration of the disease had no effect on dynamics of acute phase characteristics. Methotrexate injections resulted in markedly delayed development of clinical signs of improvement compared with laboratory values. CFP levels fell down much faster than ESR, Remission or low activity of RA (estimated from DAS28) occurred only in 38% of the cases after 3 month monotherapy by methotrexate injections.

Primary end points were functional disability, pain, joint score, and erythrocyte sedimentation rate at 6 and 12 months and progression of radiologic abnormalities at 12 months. Statistically significant advantages at 12 months for patients receiving the SAARD strategy (immediate treatment with SAARDs) with regard to all primary end points that may be clinically important are indicated by the differences in improvements from baseline and their 95% CIs. These differences were 0.3 (95% CI, 0.2 to 0.6) for disability (range, 0 to 3), 10 mm (CI, 1 to 19 mm) for pain (range, 0 to 100 mm), 39 (CI, 4 to 74) for joint score (range, 0 to 534), and 11 mm/h (CI, 3 to 19 mm/h) for erythrocyte sedimentation rate (range, 1 to 140 mm/h), all in favor of SAARD treatment. The SAARD strategy also appears to be advantageous at 6 months. Radiologic abnormalities progressed at an equal rate in the SAARD and the non-SAARD groups; the difference in progression (range, 0 to 448) was 1 (CI, -3 to 5). Analyses were based on the intention-to-treat principle and thus included 29% of patients in the non-SAARD group who discontinued the non-SAARD treatment strategy; treatment was usually discontinued because of insufficient effectiveness. The SAARD strategy including two alternative SAARDs could not be continued by 8% of patients, usually because of adverse reactions. Early introduction of SAARDs may be more beneficial than delayed introduction for patients with recently diagnosed rheumatoid arthritis." }, { "id": "pubmed23n0622_24421", "title": "[Early arthritis: action desired - treatment required].", "score": 0.009433962264150943, "content": "Rheumatoid Arthritis (RA) is the most prevalent inflammatory joint disease in adults and shows a destructive course in most cases. The outcome of the disease - functional decline and invalidity - necessitates an early therapy. Recent studies demonstrate that the initiation of the treatment with a disease modifying antirheumatic drug (DMARD) treatment within the first three months after the onset of symptoms is crucial for sustained improvement of prognosis as well as therapeutic success and outcome. In the early stage of the disease, the criteria for the classification of Rheumatoid Arthritis (RA) are frequently not met. Up to over 50% of the patients show an arthritis, which cannot be classified and therefore is seen as undifferentiated arthritis (UA). Early therapeutic intervention appears to prevent the chronification of the disease; thus an early and appropriate disease modifying therapy is mandatory. Age, gender, involvement of the hands, positive rheumatoid factor, as well as the detection of anti cyclic-citrullinated peptide antibodies (anti-CCP Ab) are predictors of the development of RA. Beside conventional X-rays, there are other imaging methods such as magnetic resonance tomography imaging, Power-Doppler or contrast medium enhanced sonography, which may enable the detection not only of synovitis but also of erosive lesions at very early stages. Those patients suffering from UA carry a high risk for the development of a destructive arthritis as seen in RA, and therefore should be treated with an adequate DMARD. In these cases methotrexate is still the drug of first choice." }, { "id": "pubmed23n0751_10102", "title": "[Case of successful pregnancy and childbirth in a rheumatoid arthritis patient treated with etanercept].", "score": 0.009345794392523364, "content": "The patient was a 34-year-old woman who, at age 23, was diagnosed with rheumatoid arthritis (RA) presenting with morning stiffness, swelling and tenderness of bilateral knee joints and metacarpophalangeal (MP) joints of the right second and third fingers, increased C-reactive protein (CRP) levels, and a high level of rheumatoid factor (RF). The patient was maintaining remission with oral dose of bucillamine (BUC; 300 mg/day); however, due to the deterioration of arthralgia at age 26, she was additionally administered 8 mg/week of methotrexate (MTX), which improved the symptoms. Thereafter, the prescription of BUC was discontinued. At age 31, she experienced onsets of swelling and tenderness in both the knee joints and wrists and in MP joints of the right second and third fingers; further, CRP levels increased to 5.44 mg/dL, resulting in increased RA activity. The concomitant administration of infliximab was started at a dose of 3 mg/kg, which helped achieve favorable RA control. At age 32, approximately 2 years before childbirth, the prescription of infliximab was changed to 25 mg/dose of etanercept administered twice a week because the patient wished to conceive. Remission was maintained even after the drug change; therefore, MTX was discontinued and the patient was treated with etanercept alone. After she was confirmed to be pregnant in March of the following year, administration of etanercept was continued for treating of RA even during pregnancy. During that time, RA was favorably controlled, and the patient gave birth to a baby boy weighing 3192 g in October of the same year. The Apgar score of the baby was favorable.

Nevertheless, their cost, as well as the related risk of side effects, especially in long-term therapies, are still high. Furthermore, there is a good deal of evidence proving loss of efficacy of such therapies in the long term, often necessitating the shift from one specific anti-TNF biological treatment to another. There are also other open debates on the amount of time a patient should undergo an anti-TNF therapy, on the possibility of inducing a complete remission in early arthritis and, once remission or low disease activity is obtained, on the possibility of interrupting the anti-TNF-based therapy. In this study we investigated whether A-Cyclosporin and Methotrexate association may be effective in maintaining low disease activity obtained by anti-TNF therapies. Twenty-three rheumatoid arthritis-affected patients, whose diagnosis was made according to ACR criteria, with a disease duration of less than 3 years, and DAS28&lt;3.2 that reached a level of low disease activity within 6-8 months from beginning anti-TNF and Methotrexate therapy, were enrolled in the study.

DAS28, Pain VAS, Erythrosedimentation Rate (ESR), and C Reactive Protein (CRP) were all tested at time 0 and at 6 months, as well as liver and kidney profiles, after the interruption of the anti-TNF therapy and the beginning of A-Cyclosporine and Methotrexate therapy. Side effects were also recorded. Of 23 patients undergoing the A-Cyclosporin and Methotrexate therapy for maintaining low disease activity in rheumatoid arthritis obtained by 6-8 months of anti-TNF therapy, 21 completed the study with a 6 month follow-up. Thirteen patients maintained clinical parameters within low disease activity values, while 8 patients showed an increase in DAS28 and other parameters. Only two patients showed an increase in blood pressure that was diagnosed after two months from the beginning of the A-Cyclosporin and Methotrexate therapy. The reduction in the dosage of A-Cyclosporin from 3mg/kg/day to 2mg/kg/day caused a slow normalization of blood pressure values. Our data seem to suggest that more than half of the patients undergoing A-Cyclosporin and Methotrexate therapy seemed to maintain low disease activity parameters of rheumatoid arthritis, obtained after 6-8 months of anti-TNF therapy. Further studies on larger populations are necessary in order to confirm such results and identify predictor factors for different responses." }, { "id": "pubmed23n0369_18149", "title": "The anti-rheumatic effect of multiple synovectomy in patients with refractory rheumatoid arthritis.", "score": 0.009174311926605505, "content": "We assessed the anti-rheumatic effects of radical multiple synovectomy (RaMS) in patients with rheumatoid arthritis (RA) who did not respond to intensive medical treatment.

There were 824 (57.5%) patients who completed &gt;or= 6 months and had paired radiographs; 46% completed 48 weeks; 31%, 98 weeks; and 19%, 147 weeks. Months between paired radiographs (time in study) averaged 23.1 (range 6-36). Mean progression rates for total, erosion, and JSN scores (5.08, 2.53, and 2.54 units per year, respectively) were significantly associated with time in study, baseline RF, ESR, CRP, swollen joint count, presence of erosions at entry, and with 20% and 50% composite clinical responses. Painful joint count and RA duration were weakly associated only with progression of erosions. Progression rates were not associated with age, sex, corticosteroid use, or prior DMARD use. Patients who completed the 3-year trial had less severe disease activity and radiographic progression than those who dropped out. In this 3-year prospective double-blind clinical trial that prohibited DMARD, retention rates (57.5%, 46%, 31%, and 19% at 0.5, 1, 2, and 3 years) were similar to those in the non-DMARD-treated placebo groups of recent published studies. Radiographic progression rates are reported for 824 non-DMARD-treated patients during RA of 1-10 years' duration. This information may be useful as background information in the interpretation of longterm clinical trials that evaluate joint radiographic outcomes." } ] } } }

The most common clinical course of severe infections in humans is a progressive illness from tonsillitis to septicemia in previously healthy young adults. A septic thrombophlebitis arising from the tonsillar veins and extending into the internal jugular vein leads to septicemia and septic emboli contributing to the development of necrotic abscesses especially in lungs and other tissues such as liver, bone and joints. In this case report, a previously healthy man with pneumonia and empyema due to F.necrophorum has been presented. A 22 year-old man suffering from sore throat for seven days was admitted to emergency department with ongoing fever and dysphagia for three days. On admission he was already taking amoxicillin-clavulanic acid and his complaints were relieved with continuation of therapy to a total of 10 days. However, five days after the cessation of treatment he developed productive cough, fever and generalized myalgia. On physical examination, there were crackles on right lower lung, and chest X-ray revealed pulmonary consolidation on the right middle lobe. Levofloxacin therapy was started based on the diagnosis of pneumonia. While polymorphonuclear leucocytes and intracellular gram-negative bacilli were seen in Gram stained sputum smear, sputum culture was reported as normal flora. Although the patient's status had started to improve with treatment, his condition deteriorated with development of fever and dyspnea. Chest X-ray revealed consolidation, pulmonary infiltrates, pleural effusion and air-fluid level on the right.

In immunocompetent patients, lung consolidation, pleural effusion or cavities are scarce. A 29-year-old Asian male was admitted to our hospital with complaints of cough and fever that had persisted for a month. As a chest computed tomography scan showed consolidation in his left lower lobe, he was initially diagnosed with pneumonia and received antibiotic treatment. A second review of the chest computed tomography image revealed multiple cavities and pleural effusion. Flexible fiberoptic bronchoscopy was subsequently performed, bronchoalveolar lavage fluid and serum cryptococcal antigen tests were positive. Cryptococcus capsules were observed in bronchoalveolar lavage fluid ink stain. Histopathological examination of a percutaneous lung biopsy from the left lower lobe further revealed granulomatous inflammation, and periodic acid-Schiff staining showed red-colored yeast walls, signifying pulmonary cryptococcosis. The patient was then treated with a daily dose of fluconazole (0.4 g), but the cough and fever still persisted. We therefore changed treatment to voriconazole (0.2 g, twice a day), and the patient's clinical outcome was satisfactory.

Chest X-ray showed consolidation/atelectasy in 58 (92.1%) and pleural effusion (PE) in 17 (27.0%), of which 11 were empyema (17.4% of all admissions).

Sixty-one children (96.8%) were prescribed antibiotherapy. The median length of hospital stay was five days. Patients with PE were older, had a longer course of fever, higher inflammatory parameters, longer hospital stay and longer course of iv antibiotics. Compared to the prior study we found greater severity of CAP, with higher prevalence of PE and empyema. Nevertheless there was a shorter course of fever during hospital stay and shorter hospital stay. We also noticed less antibiotic prescription prior to admission and greater prescription of ampicillin during hospital stay. In the literature, the higher severity of CAP has been partially attributed to the emergence of more aggressive serotypes of Stretococcus pneumoniae not included in the heptavalent vaccine. There is therefore a greater interest in new vaccines containing them.

In ventilated patients with either CAP or HAP, respiratory secretion sampling using noninvasive techniques should be conducted upon clinical suspicion of VAP and before starting a new antibiotic treatment. Antibiotic therapy according to approved guidelines should be started as soon as possible and maintained during the first 48 hours if the patient's evolution is satisfactory and condition has stabilized. Then, initial antibiotic treatment should be adjusted according to cultures. If there is a clear diagnostic alternative to VAP and cultures are negative, this is the only case in which antibiotic treatment could be withdrawn. If the patient's clinical evolution is inadequate (persistence of fever, leukocytosis, increasing infiltrates, and respiratory failure), fiberoptic bronchoscopy with PSB and BAL and modification of the initial antibiotic regimen should be sought.

Initial treatment effectiveness, age, pneumonia type, presence of mechanical ventilation, comorbidities, coma, antibacterial treatment, pathogen isolation and treatment changes were assessed. Logistic regression analysis was performed to detect factors associated with non-resolving pneumonia and mortality. Etiotropical treatment was administered to 30.9% of patients. Initial antibacterial treatment was corrected in 64.7% of all cases. After 21-30 days from the pneumonia onset survived 66.2% of patients (n=43). Pneumonia course could be evaluated in 52 cases. Delayed resolution of the pneumonia was stated in 32.7% of cases (n=17). Pneumonia was cured or condition improved in 64.3% of the CAP patients (n=9) and 68.4% of the hospital-acquired pneumonia patients (n=26).

In conclusion, the initial pneumonia treatment failure increases probability of the non-resolving pneumonia.

This study aimed to investigate the clinical and electrophysiological characteristics of EMA. Video-EEG monitoring was carried out in 6 patients with EMA, and 2 of them were examined with simultaneous deltoid muscle surface electromyogram (EMG). The clinical and EEG characteristics, treatment and prognoses of EMA were analyzed. Of the 6 patients, 3 were female, and 3 were male. The age of onset was from 2 years and 3 months to 11 years (average 5 years and 2 months). MA was the sole seizure type in 5 patients. One patient presented generalized tonic clonic seizures (GTCS) at the onset and then switched to MA. The manifestations of MA included an impairment of consciousness of variable intensity, rhythmic myoclonic jerks with evident tonic contraction mainly involving the upper extremities, a deviation of head and body to one side or asymmetrical jerks observed in some cases, a duration ranging from 2 to 30 s, an abrupt onset and termination, a high frequency of attacks, at least several times to over 30 times per day, and easily provoked by hyperventilation. The ictal EEG consisted of rhythmic 3 Hz spike and wave discharges that were bilateral, synchronous and symmetrical in all patients. The deltoid muscle EMG recording in 2 patients showed rhythmic myoclonus at the same frequency as the spike and waves. The interictal EEG showed generalized spike and wave discharges in all patients, and focal discharges in some patients. Valproate was the drug of choice, which was often combined with other antiepileptic drugs. The ages at follow up ranged from 6 years and 4 months to 19 years.

It is easy to diagnose JME if one thinks of it while the history should be thoroughly analyzed. An EEG recording during sleep confirms the diagnosis. An early diagnosis of JME permits adequate prognosis of the subsequent course of epilepsy, and adequate therapy brings remission in most of the patients. If treatment starts following the large number of severe GTC seizures, the response to therapy is incomplete. The persistency of the illness throughout the life, the need for continuous medication and therapeutic unresponsiveness in cases with late diagnosis, do not justify the increasing misconception that JME is of benign nature. Diagnosis of JME is rare because of insufficient familiarily of physicians with the illness. Juvenile myoclonic epilepsy (JME) is an idiopathic generalized epileptic syndrome characterized with the combination of myoclonic, generalized tonic-clonic (GTC) and absence seizures that are readily provoked by sleep deprivation. Forty-three patients, aged from 14 to 51 years, participated in a 5-year follow-up study. Diagnosis was made according to the criteria (Table 1) for diagnosis of JME set by Panayiotopoulos et al. (1994). Nineteen patients made their first contact with a neurologist at the Institute of Neurology and were diagnosed as JME, while the remaining 24 were referred to from other medical institutions with a diagnosis of therapy resistant to focal epilepsy. All patients underwent a somatic and neurological examination, \"mini mental test,\" EEG in waking and CT scan of the brain. Some patients had EEG performed during sleep and some had MRI of the head. JME began between 9 and 26 (average 17) years. All patients had myoclonic seizures, 98% had GTC and 23% absence seizures. The first myoclonic seizure occurred between 9 and 24 years while the frst GTC seizure occurred between 10 and 32 years. Myoclonic seizures (83% of patients) and GTC seizures (70% of patients) occurred most often immediately after awaking. The most frequent provocative factors were insufficient sleep, alcohol abuse and tiredness. Epilepsy in the family was present in 39%, focal neurological deficiency in 9% and pathological findings on of CT and MRI in 7% of patients. Waking EEG was pathological in 77% of patients; it included generalized spike-wave discharges in 73%, multiple spike-wave complexes in 33% and focal discharges in 12% of patients, respectively. In all 26 patients tested, sleep EEG was pathological most often with multiple spike-wave complexes in 85% and 3-4 Hz spike-wave complexes in 57% of patients. The correct diagnosis of JME following a comprehensive examination was made in 24 (56%) patients after a delay of 1 to 35 years. In 24 patients with delayed diagnosis of JME the replacement of earlier medication with valproic acid (VPA) induced remission in 18 patients (75%) while 1 patient (4%) experienced a reduction in the number of seizures. Five patients (21%) did not respond to VPA medication: 2 due to a weak compliance, another 2 due to inefficient medication and 1 because of the preexistent malabsorption syndrome. In 19 patients (44%) with initial diagnosis of JME, VPA was introduced immediately upon diagnosis. Of them, 15 (79%) had excellent response to VPA, 1 refused therapy and for 3 patients there is no information. In 2 patients VPA was substituted due to side effects (hepatotoxicity and alopetia) with lamotrigine (low doses), which brought about decrease in frequency and mitigation in myoclonic seizures." }, { "id": "pubmed23n0311_15596", "title": "[Differential diagnosis in idiopathic generalized epilepsies with tonic-clonic seizures: assessment of the use of ambulatory EEG and video/EEG monitoring].", "score": 0.016328978938949613, "content": "The value of long-term cassette EEG (24-EEG) and Video/EEG for differential diagnosis and classification of idiopathic epilepsies with generalised tonic-clonic seizures (GTCS) was evaluated in twenty-eight patients.

There is no prior personal history, although in some patients 1 or 2 isolated febrile convulsions may occur prior to the onset of myoclonias. A family history of epilepsy or febrile convulsions is present in 30% of cases. Myoclonic attacks are short and mild, they involve mainly the head and upper limbs. The psychomotor development continues normally after the onset of seizures. The EEG shows a normal background activity and generalized spike-wave or polyspike-wave discharges associated with the myoclonias. These abnormalities are activated by drowsiness and during the first stages of sleep. A clinical and EEG photosensitivity is present in one-third of the patients. Myoclonias can be easily controlled by valproate monotherapy. Rare grand mal seizures can occur during adolescence, after withdrawal of drug treatment.

The onset occurred between the age of 8 months and 12 years, with the peak at 1-4 years of age, accounting for 61%; a late onset which occurred after 8 years of age, was unusual. Furthermore, one patient who developed LGS at the age of 13 years and remained to have all the features of seizures and EEG at 35 years of age was identified as adult's LGS. Forty-three patients were classified as symptomatic, perinatal events were the predominant factors in this group. The others were cryptogenic. It was noted that 11 cases had a history of West syndrome. A transformation process from West syndrome to LGS was observed in another 7 cases. Every patient had two or more seizure types during the course of the disease; tonic seizure, atypical absence seizure, head drop or sudden falls were the characteristic types. The degree of mental deficit was variable from slight to profound deterioration, but mental and behavioral disturbances existed in every case as a rule. In all cases electroencephalogram (EEG) background was abnormal and consisted of diffuse slow spike-and-waves (1-1.5CPS), predominant in frontal and temporal regions. Twenty-four cases had the polyspike-wave. Bursts of fast rhythms (10-14CPS) were observed in 29 patients during sleep. The choice of antiepileptic drugs (AEDs) was based on the seizure types; routinely, 2 or more kinds of AEDs were used in combination, the classic drugs, valproate and clonazepam were firstly recommended; the other drugs, such as lamotrigine and topiramate that are used as add-on therapy were further consideration.

The subjects included 30 patients, who fulfilled the following modified International League Against Epilepsy (ILAE) criteria for MAE, and whose main seizures were captured by video-electroencephalographs (EEG) or polygraphs. The modified ILAE criteria includes: (1) normal development before onset of epilepsy and absence of organic cerebral abnormalities; (2) onset of myoclonic, myoclonic-astatic or astatic seizures between 7 months and 6 years of age; (3) presence of generalized spike- or polyspike-wave EEG discharges at 2-3 Hz, without focal spike discharges; and (4) exclusion of severe and benign myoclonic epilepsy (SME, BME) in infants and cryptogenic Lennox-Gastaut syndrome based on the ILAE definitions.

All patients had a history of drop attacks, apart from ten patients with myoclonic seizures. Myoclonic seizures, involving mainly the axial muscles were classified into those with mild intensity not sufficient to cause the patients to fall (n=10) and those that are stronger and sufficient to cause astatic falling due to flexion of the waist or extension of the trunk (n=6). Patients in the atonic group fell straight downward, landed on their buttocks, and recovered immediately. Analysis of the ictal EEGs showed that all attacks corresponded to the generalized spike or polyspikes-and-wave complexes. In the atonic form, the spike-and-wave morphology was characterized by a positive-negative-deep-positive wave followed by a large negative slow wave. In two patients, the intensity of the atonia appeared to correspond to the depth of the positive component of the spike-and-wave complexes. We did not detect any significant differences in the clinical and EEG features and prognosis, between the atonic and myoclonic groups.

This is because the sound and evident clinical characteristics on which it was identified some 30 years ago have evolved, mostly as a consequence of changes in the practical management of epilepsies and to the description of myoclonic components in a variety of other generalised epilepsies with absences. Myoclonic absences (MA) are described as typical absences with sudden onset and offset that are associated with generalised spike and wave (SW) discharges on the ECG, with distinctive traits. Clinically, absences are associated with axial hypertonia (the subject usually bends forward and slightly raises their shoulders and arms), and jerks synchronous with the SW discharges. Neurophysiologically, axial hypertonia and rhythmic jerks may be recorded on polygraphic surface electromyogram leads in association with the typical SW discharges; as such, despite an ECG, the diagnosis may be missed in the absence of video documentation of the seizure and/or adequate polygraphy. MA need to be distinguished from absences with other types of prominent myoclonic accompaniment (perioral, eyelid, limbs).The prognosis of EMA remains variable. Modern therapeutic combinations, such as valproic acid and ethosuximide, or valproic acid and lamotrigine, are usually effective; however, in a proportion of patients, seizures are resistant to drug treatment.

The 101 children (58 boys, 43 girls) met the following inclusion criteria: onset of the epilepsy with febrile or afebrile GTCS in the first 5 years of life, absence of primary organic brain lesion or progressive brain disease, severe course with frequent febrile and/or afebrile GTCS, failure of conventional anticonvulsive therapy. The epilepsy predominantly afflicts normally developed infants, boys and girls being about equally affected. The epilepsy begins with frequent febrile or afebrile GTCS, characteristically of long duration and often with alternating lateralization. In half of the cases additional myoclonic or myoclonic astatic seizures and/or absences occur. The initial GTCS phase is the same in epilepsies with and without minor seizures. Erratic myoclonias are especially characteristic. With advancing age, the symptomatology becomes increasingly polymorphic due to the occurrence of additional simple and complex focal and tonic seizures. Severe impairment of mental development soon after onset is a leading symptom. The overall death rate was 9%.

The study proves beyond doubt that in the majority of the HB antigen carriers such histological changes of the liver can be found that can be attributed only to an infection by the hepatitis virus. The majority of the HB antigen carriers are suffering either from the chronic focal (58%) or from the diffuse (21%) persistent hepatitis. A smaller percentage is suffering from more dangerous hepatopathies (acute viral hepatitis 4,2%, hepatitis chron. aggressiva 4.2%, cirrhosis 1,4%). The kind of the illness can be determined with the histological examination only because of the absence of the clinical symptomatology and because of the liver function tests are in such cases frequently normal. Our investigations indicate that the diffuse and focal forms of persistent hepatitis can remain unchanged overlong periods and the same histological findings over a number of years. The chronic persistent hepatitis, however, may develop through clinically imperceptible changes into a chronic aggressive hepatitis, and the inapparent acute hepatitis can even pass over directly into cirrhosis. The identification of various forms of hepatitis, from light instances to the most severe cases, among the HB antigen carriers proves that the acute viral hepatitis of the type B may have in all the phases of its development a clinically asymptomatic course; it may even asymptomatically pass over into hepatopathies of the most severe kinds.

The prevalence rate of HBV carriers decreased from 3.0% to 1.2% in these 10 years, and that of HCV decreased from 0.9 to 0.4% in these 4 years. Prevalence rate of HBV peaks at 50s and that of HCV peaks at 60s. Due to nearly complete screening of donated blood, post-transfusion hepatitis almost disappeared. HBV vaccine for neonates born from infected mothers reduced the new incidence of HBV carriers. In HBV carriers seroconversion of HBeAg to HBeAb occurs at teens with transient hepatitis and appearance of mutant virus. Ninety percent of the carriers remains healthy for the lifetime but some of them aggravate into chronic hepatitis leading to HCC (hepatocellular carcinoma). In HCV acute infection at adult age succeeds to chronic infection and eventually to liver cirrhosis with sporadic appearance of HCC. On the other hand, less than 50% of HCV carriers seem to be asymptomatic and do not lead to grave disease. In HBV carriers tendency to reject the virus occurs and eventually HBV is cleared in some percentage of the population. In contrast HCV does not tend to be cleared. HBsAb is a defensive antibody. In contrast HCVAb is not a defensive antibody but an infective antibody like HBcAb. DNA polymerase is a good marker of disease state in HBV, and HCV RNA is a good marker of HCV proliferation.

And the proportion of cases with abnormal SGPT levels decreased with the progress of stages (p less than 0.05).

The objective of this study was to estimate the morbidity of this syndrome in these patients, to assess the safety and efficacy of our graduated refeeding regimen, and to emphasize the importance of this syndrome. One hundred fifty-eight patients with gastrointestinal fistula during the past 2 y were reviewed. Fifteen of these patients were diagnosed as having refeeding syndrome. They were started on the refeeding procedure according to our regimen, and changes in their serum levels of electrolytes were recorded. The symptoms and signs they presented were noted. All patients were successfully advanced to full nutrition support. During the refeeding procedure, patients presented with weakness, paralysis of limbs, slight dyspnea, paresthesia, tachycardia, edema, and diarrhea. Serum phosphorus concentration decreased in all patients within 24 h of refeeding, reaching a mean nadir after 3.3 +/- 1.5 d and another 6.1 +/- 2.1 d to return to above 0.70 mM/L upon phosphorus supplementation. Three patients treated with growth hormone presented more severe hypophosphatemia (&lt;0.20 mM/L) than the others. 1) Refeeding syndrome occurs commonly in patients with malnutrition secondary to gastrointestinal fistula. 2) Alterations in phosphate metabolism are central to the refeeding syndrome. 3) Supplementation with electrolytes (including especially phosphate) and vitamins is the focal point of the treatment of this syndrome. 4) Growth hormone treatment may aggravate hypophosphatemia." }, { "id": "pubmed23n0318_5663", "title": "[Malnutrition and total parenteral nutrition: a cohort study to determine the incidence of refeeding syndrome].", "score": 0.01896117900790798, "content": "The Refeeding Syndrome is conformed by a series of clinical manifestations related to electrolytic alterations associated with the restarting of the nutritive contribution both enteral and parenteral.

There is no unequivocal definition of RFS, although hypophosphatemia is recognized as a crucial factor in its pathogenesis. RFS can be responsible for cardiovascular complications, such as heart failure, left ventricular damage, and arrhythmias, because of different potential mechanisms: electrolyte imbalances, increased retention of sodium and liquids secondary to insulin secretion, and excessive fat emulsion supplementation. We report on the case of a 13-y-old male patient with severe AN in whom a delayed and reversible myocardial dysfunction was documented during cautious nutritional replenishment, even in the absence of serum electrolyte imbalances. Seven days after the inception of integrative enteral nutrition, heart failure was unexpectedly documented as follows: reduction in fraction ejection, presence of mild bilateral perimalleolar edema, and increased n-terminal prohormone of brain natriuretic peptide. A more pronounced water restriction protocol and delayed achievement of goal feeding rate, resulting also in lower sodium intake, were implemented to reduce cardiac overload with a full resolution of the complication in approximately 2 mo. Refeeding patients with AN could be complicated by heart failure despite cautious nutritional replenishment and regardless of electrolyte imbalance, even in a later phase of recovery. Therefore, strict adherence to recommendations for nutritional replenishment and close monitoring of cardiac function should always be considered when refeeding patients with AN." }, { "id": "wiki20220301en110_39302", "title": "Refeeding syndrome", "score": 0.017261904761904763, "content": "Clinical situations The syndrome can occur at the beginning of treatment for anorexia nervosa when patients have an increase in calorie intake and can be fatal. It can also occur after the onset of a severe illness or major surgery. The shifting of electrolytes and fluid balance increases cardiac workload and heart rate. This can lead to acute heart failure. Oxygen consumption is increased which strains the respiratory system and can make weaning from ventilation more difficult. Diagnosis Refeeding syndrome can be fatal if not recognized and treated properly. An awareness of the condition and a high index of suspicion are required in order to make the diagnosis. The electrolyte disturbances of the refeeding syndrome can occur within the first few days of refeeding.

In patients with severe undernutrition it is almost always necessary to use oral nutrition support and/or artificial nutrition, besides ordinary food; enteral nutrition should be a preferred route of feeding if there is a functional accessible gastrointestinal tract. Refeeding of severely malnourished patients represents two very complex and conflicting tasks: (1) to avoid \"refeeding syndrome\" caused by a too fast correction of malnutrition; (2) to avoid \"underfeeding\" caused by a too cautious rate of refeeding. The aim of this paper is to discuss the modality of refeeding severely underfed patients and to present our experience with the use of enteral tube feeding for gradual correction of very severe undernutrition whilst avoiding refeeding syndrome, in 10 patients aged 22 ± 11.4 years and with mean initial body mass index (BMI) of 11.2 ± 0.7 kg/m(2).

On admission they were all on a weight-losing course and weighed 37.0+/-8.0 kg (mean +/- SD) following a weight loss of 14.2+/-7.2 kg. On ECG recordings there was a prolongation of the QT interval and an increased QT dispersion. Serum concentrations of sodium, potassium and magnesium were with few exceptions normal. Serum concentrations of creatinine were high in relation to the low body weight, indicating protein catabolism. The first 2 wk of refeeding resulted in a weight gain of 1.7+/-0.2 kg without signs of refeeding syndromes or electrolyte aberrations. QT prolongation and dispersion normalized within the 3 d of refeeding. It is concluded that oral refeeding of patients with eating disorders and weight loss can be performed efficiently and without causing refeeding syndromes. QT pathology, a consequence of acute starvation and a risk factor for cardiac arrhythmias, normalizes within days. In view of the need to balance adequate refeeding and reduction of QT pathology against the risks of refeeding syndromes the start of refeeding of severely emaciated patients is best performed in a hospital setting where monitoring of ECG and serum electrolytes is possible." }, { "id": "wiki20220301en302_17929", "title": "Anorexia nervosa", "score": 0.013176638176638177, "content": "Refeeding syndrome The rate of refeeding can be difficult to establish, because the fear of refeeding syndrome (RFS) can lead to underfeeding.

Thus, we studied the response to a four-step dietary replenishment routine in eight hunger strikers who refused food for 43 d. In this retrospective, observational study, we assessed the safety and efficacy of the refeeding procedure and analyzed the clinical and nutritional course of the cohort during both starvation and refeeding, mainly on the basis of clinical as well as a few biochemical determinations. During starvation, average weight loss was about 18% and, with the exception of occasional oral vitamins and electrolytes, the subjects consumed only water. Available body-composition and biochemical profiles showed no clinically significant changes during starvation, but one-half of the group displayed spontaneous diarrhea at some time before refeeding. Stepwise nutritional replenishment lasted for 9 d, after which all patients tolerated a full, unrestricted diet. Only one episode of diarrhea occurred during this phase, and both clinical and biochemical indexes confirmed a favorable clinical course, without any manifestation of refeeding syndrome. In conclusion, we observed the following: 1) Hypophosphatemia and other micronutrient imbalances did not occur, nor was macronutrient intolerance detected. 2) Despite some episodes of diarrhea, nutritional replenishment was not associated with significant enteral dysfunction. 3) There was some fluid retention, but this was mild. 4) Acute-phase markers were abnormally elevated during the refeeding phase, without associated sepsis or inflammation." } ] } } }

A long statement full of rather confusing data. We can attack that question in two ways: by looking at the key data and going all the way to the diagnosis we are considering or by discarding one by one. The choluria, LDH, presence of panagglutinin and the peripheral blood smear "smells" like hemolytic anemia. Answer 1 cannot be because a marrow aplasia does not explain the choluria, the elevation of LDH, nor in the study of irregular antibodies is positive in the form of panagglutinin; an aplasia is a marrow failure characterized by a total or partial disappearance of hemopoietic progenitors. In addition, pancytopenia is not observed, which is what would incline us more towards this pathology. Answer 2 is not possible either, since a spherocytosis does not justify the presence of panagglutinin. Answer 3 is the one I consider correct: an autoimmune hemolytic anemia would justify the data given: elevated LDH and bilirubinemia due to red cell destruction, polychromatophilia, spherocytosis and anisocytosis because the marrow is working hard to try to compensate for the anemia, which is regenerative. The study of irregular antibodies and the presence of panagglutinin also supports this response, since the binding of an antibody to the hematocyte promotes its lysis and destruction. The girl presents cough and fever, consistent with a respiratory infection. And the initial treatment is corticosteroids. This is confirmed by Sans Sabrafens in his book "Clinical Hematology" [1]. Answer 4 gives rise to considerable doubt; it is not possible because a pernicious anemia does not justify the presence of panagglutinin although it would justify the elevation of LDH and bilirubin; moreover, it is an intramedullary, arregenerative hemolysis, there is no reticulocytosis or release into the blood of immature forms in an attempt to compensate and fix the situation. Answer 5 is not true because no blasts are seen in the blood nor does it explain the presence of panagglutinin.

A 32-year-old woman with cerebral palsy from childbirth comes to the emergency department for a few days of dark urine associated with an episode of high fever and dry cough. On admission, the CBC showed 16900 leukocytes/mm3 (85% S, 11% L, 4% M), hemoglobin 6.3 g/dL; MCV 109 fl, 360000 platelets/mm3. In the biochemistry LDH 2408; bilirubin 6.8 mg/dl, (unconjugated bilirubin 6.1 mg/dl), normal GOT and GPT. The morphological study of blood showed macrocytic anisocytosis with frequent spherocytic forms and polychromatophilia without blasts.

The patient was a 16-month- old boy.Since the first month of life, he started to have repeatedly fever, diarrhea, shortness of breath, lymphadenopathy, hepatosplenomegaly, anemia (HGBmin 50 g/L) and thrombocytopenia (min 35 × 10⁹/L) . But multiple exams showed a normal peripheral blood leukocyte count, hypergammaglobulinemia (IgG 19 800 mg/L, IgA 1 710 mg/L, IgM 2 590 mg/L) and significantly increased serum vitamin B12. Flow cytometric measures showed that CD3⁺ CD4⁻ CD8⁻ T lymphocytes significantly increased ( &gt; 10%) at four times. The count of CD3⁺ TCRαβ⁺ CD4⁻ CD8⁻T lymphocytes (double negative T cells; DNTs) &gt;3% twice. The genetic test showed that 309th FAS gene area showed heterozygous mutations, the boy was diagnosed as ALPS. Added examinations of lymphocytes apoptosis induced by FAS was positive. He was treated with prednisone 15 mg once daily and immunomodulator 150 mg three times a day, while in maintaining period with normal levels of hemoglobin and platelet, the dose of prednisone was reduced gradually. Till now, the patient has been treated and observed for 8 months. We retrieved the reports of ALPS in the databases at home and abroad published in recent 10 years, more than 400 cases reported from foreign countries, but there were only 5 domestic cases. Among those, 4 had onset in infancy and 1 at 6-years of age. All the cases presented servere lymphadenopathy and hepatosplenomegaly with anemia (4 of them with hemolytic anemia) and thrombocytopenia. Three cases had a history of frequent infection, one of them had glomerulonephritis. All patient with significant high level of serum immunoglobulin ( &gt; 1.5 times upper limit of normal range), in 3 of them serum vitamin B12 was &gt; 1.5 pg/L (the other 2 cases missed the exam). In 5 cases CD3⁺ CD4⁻ CD8⁻T cells &gt; 10%, and in 2 case DNTs were 8.9% and 15.7% respectively (the other 3 cases missed the exam). Three cases were clearly detected with FAS mutations. All patients were treated with corticosteroid, 2 of them were added with mycophenolate mofetil. The therapy presented effective result in early 1-3 months, but no long-term follow-up reports were available. ALPS is a disorder of disrupted lymphocyte homeostasis caused by defective Fas-mediated apoptosis, and it is one of the primary immunodeficiency diseases. The onset of the disease occurs during infancy mainly. Clinical lymphoid hyperplasia and autoimmune phenomena are outstanding signs, which can be associated with frequent infections and allergies. The level of serum vitamin B12 &gt; 1.5 pg/L and the count of CD3⁺ CD4⁻ CD8⁻ T cell show important significance. Exact diagnosis should depend on detecting DNTs and FAS gene." }, { "id": "pubmed23n0297_3204", "title": "[Autoimmune hemolytic anemia with eosinophilia in elderly patient].", "score": 0.014601652011723955, "content": "A 70-year-old woman was admitted to our hospital in November 1992 for evaluation of anemia.

This is a 14-year retrospective study of AIHA cases collected at the department of pediatric emergency and reanimation of Hedi Chaker University Hospital in Sfax. We included patients under 14 years old with clinical and biological features of hemolysis and a positive direct antiglobulin test (DAT). The selected patients' demographic characteristics, physical signs, laboratory findings, and treatment responses were recorded. Thirteen cases of AIHA were collected, including 8 girls and 5 boys. The median age at diagnosis was 4 years and 6 months (range: 8 months to 13 years). Consanguinity was reported in 6 cases and 4 patients had a previous infection history. The onset of AIHA was progressive in 9 cases, marked by an anemic syndrome and hemolysis symptoms in 6 and 8 cases, respectively. The clinical triad (pallor, jaundice and splenomegaly) was found in only 4 cases. At the time of diagnosis, the median hemoglobin (Hb) level was 6g/dL (range: 4.2 to 9.2g/dL), anemia was non-regenerative in 2 patients. Thrombocytopenia and neutropenia were noted in 5 and 1 patient, respectively. Peripheral smear examination showed spherocytosis in 2 cases. All the patients had a positive DAT. Of these, 10 were positive with IgG and 3 with both IgG and C3d. AIHA was secondary to other conditions in 9 patients: infection (3 cases), autoimmune disease (4 cases), and immunodeficiency (2 cases). All the patients received first-line corticosteroid therapy but only 8 of them required blood transfusions due to severe anemia. Complete remission was obtained in 7 cases. Corticosteroid resistance and dependence were noted in 1 and 2 cases, respectively. During evolution, additional therapy was indicated in 4 patients and it included cyclosporine A, azathioprine, and mycophenolate mofetil (MMF).

The pathogenesis of the disease is not known, but vascular endothelial damage is prominent. Therefore, it progresses with thrombocytopenia, anemia, leukopenia and this hematological findings can be confused with hematological malignancies. Acute lymphoblastic leukemia (ALL) is a malignancy included in differential diagnoses and occurs as a result of mutations occuring at a stage of differentiation in the lymphoid precursor cells in the bone marrow. In this study, we present a case of ALL who was diagnosed with CCHF simultaneously. A 43-year old female patient who works in the library and does not have a chronic disease other than asthma and thyroid disorder, has admitted to our hospital with the complaints of intermittent fever, weakness, generalized joint and body pain for about 3 weeks. She had fever and the physical examination revealed bilateral cervical and right postauricular lymphadenopathies.

Brucella Rose Bengal and Coombs tube agglutination was found be negative. As the cytopenia of the patient deepened, the patient was accepted to have neutropenic fever and it was planned to start piperacillin-tazobactam 4 x 4.5 g/day and two units of erythrocyte replacement therapy. When the patient's history was questioned again, it was learned that she had a tick on her neck about three weeks ago and she had removed the tick herself; 4-5 days later she had the complaints of fever and flu like symptoms and also diarrhea complaints lasting for 3-4 days. Considering the current anamnesis and laboratory findings, the patient was thought to have CCHF and the patient was isolated. The serum sample taken from patient with an initial diagnosis of CCHF and sent to Department of Microbiology Reference Laboratory Public Health Agency of Turkey. The patient was referred to the Antalya Training and Research Hospital. The patient's CCHF serum result was positive. Ribavirin treatment was not initiated in the patient who was accepted to be in the convalescence period, piperacillin-tazobactam 4 x 4.5 g/day treatment was continued and supportive treatment was given. In the follow-up, as the patient's neutropenia, thrombocytopenia and lymphocytopenia still continuing, she was transferred to hematology clinic for malignancy examination and bone marrow biopsy performed by hematology and B cell ALL was diagnosed. She was accepted to be convalescent in terms of CCHF and chemotherapy was started for ALL treatment by hematology. The patient is still being followed up by the hematology clinic and allogenic hematopoietic stem cell tranplantation is planned for the patient.

Severe neutropenia was defined as a neutrophil count &lt;0.5 x 10(9)/L, and severe thrombocytopenia as a platelet count &lt;30 x 10(9)/L. We identified the following cytopenias: AHA (17 cases), severe thrombocytopenia (16 cases), aplastic anemia (2 cases), severe neutropenia (1 case), refractory sideroblastic anemia (1 case), and pure red cell aplasia (1 case). Three patients simultaneously presented 2 types of severe cytopenias. Twenty-seven patients (77%) were female and 8 (23%) male, with a mean age at diagnosis of cytopenia of 51.7 years (range, 18-84 yr). Immunologic markers were detected in 19 (68%) of 28 patients, the most frequent being hypocomplementemia in 16 (57%), cryoglobulins in 15 (54%), antinuclear antibodies in 12 (43%), and rheumatoid factor in 5 (18%). Other associated processes were autoimmune diseases in 14 (50%) of 28 and human immunodeficiency virus (HIV) coinfection in 3 (9%) of 32. We found clinical and immunologic differences between HCV patients with AHA and those with severe thrombocytopenia. Patients with HCV-related AHA showed a higher prevalence of associated autoimmune diseases (71%), cryoglobulins (67%), and cirrhosis (59%). All had a good response to corticosteroids, but a poor prognosis (47% mortality). In contrast, patients with HCV-related severe thrombocytopenia had a lower prevalence of associated autoimmune diseases (11%), a poorer response to corticosteroids (55%), and lower mortality (6%), with HIV/HBV coinfections in some patients. The 35 cases presented demonstrate that different types of immune-mediated cytopenias may be severe and clinically significant in patients with HCV infection.

The clinical manifestations, laboratory examination data and therapeutic strategies were analyzed. A literature search (search terms included 'eperythrozoonosis' and 'hemophagocytic syndrome') was conducted using CNKI, Wanfang database, Chinese biomedical literature database and PubMed to include recently published studies (searched from the database establishment to January 2017). <bResults:</b Four patients were included in the study. One was boy and the other three were girls. The age range of the 4 patients was between 9 months and 17 years (9 months, 2 years and 17 years, 11 months respectively). All the patients presented with recurrent high fever. During the course of fever, 3 patients presented with rash, and 2 patients presented with joint pain and swelling, which mimicked systemic juvenile idiopathic arthritis. Only 1 patient had the contact history of infectious disease. All patients had normal or decreased white blood cell count ((0.80-13.12)×10<sup9</sup/L), suffered from varied degrees of anemia and showed the increased C reactive protein (13.0-84.7 mg/L) anderythrocyte sedimentation rate (13-72 mm/1 h). Examination of peripheral blood smears confirmed eperythrozoonosis. After fever continued about 1 month, all the 4 patients rapidly progressed. Among the 4 patients, 1 patient died for giving up further therapy, and the other 3 patients completely recovered after treatment, including azithromycin for the treatment of eperythrozoonosis, and high-dose intravenous methylprednisolone pulse therapy and human immunoglobulin for the treatment of HPS. For the disease not satisfactory, the hemophagocytic lymphohistiocytosis-2004 (HLH-2004) protocol is given. After the hospitalization of 1 to 2 months, the conditions improved and the children were discharged from hospital. Three patients were followed up for 8 months to 2 years, and their conditions were stable. In the PubMed database, no report was found. Nine cases of children with eperythrozoonosis were found in CNKI, Wanfang database and Chinese biomedical literature database, and 1 case was complicated with HPS. These findings, taken together our report, provided the data of 5 children with eperythrozoonosis complicated with HPS (4 cases were younger than 2 years old). A patient had contact history of infectious disease. Five patientss showed fever of unknown origin. All the patients had severe eperythrozoonosis, and 2 cases at younger age died. <bConclusions:</b Children with eperythrozoonosis often present with the protracted fever of unknown origin, and clinical manifestations mimic those of juvenile idiopathic arthritis (systemic type). The patients with eperythrozoonosis of mild-to-moderate disease severity may have a good prognosis. Children with severe eperythrozoonosis, especially those HPS cases with early onset before 2 years old, may have high risk of mortality. Once the patient's condition aggravates in the course of fever, HPS should be highly suspected. For the patients with eperythrozoonosis complicated with HPS, early diagnosis and the combination of anti-infection with the treatment of HPS are crucial for a good prognosis.

Older nonsurvivors did not differ from nonsurvivors 55 years or younger with respect to gender, smoking history, ARDS risk factors, ARDS identifying characteristics, APACHE II (acute physiology and chronic health evaluation), number of organ failures, or the incidence of sepsis. In the 48 h prior to death, nonsurvivors 55 years and younger had more organ failure (3.4 +/- 0.2 vs 2.8 +/- 0.2; p = 0.03), higher fraction of inspired oxygen (0.82 +/- 0.03 vs 0.68 +/- 0.03; p = 0.008), and higher positive end-expiratory pressure levels (13 +/- 1 vs 8 +/- 1; p = 0.001) than older nonsurvivors. Despite more severe expression of disease, only 32 (50%) nonsurvivors 55 years and younger had support withdrawn. Significantly more nonsurvivors older than 55 years (73%) had support withdrawn (p = 0.009). Even in the absence of chronic disease states, withdrawal was more likely for patients older than 55 years (21/51) than in those 55 years and younger (3/32; p &lt; 0.001). Mortality is significantly higher for patients with ARDS older than 55 years. Decisions to withdraw support are made more often in ARDS patients older than 55 years.

The register was used to determine the 7-day ICU mortality per acute respiratory distress syndrome classification based on the standard and corrected Pao2/Fio2 ratio. The retrospective dataset correlated the Paco2 with Pao2/Fio2 ratio over time in patients with assumed stable oxygenation. The model demonstrated an increased difference between the standard and corrected Pao2/Fio2 ratios by a lower Fio2 and atmospheric pressure and higher Pao2 and Paco2. Reclassification of severe acute respiratory distress syndrome resulted in an increase in mortality from 28.1% for standard Pao2/Fio2 to 30.6% for corrected Pao2/Fio2 ratios. Acute Physiology and Chronic Health Evaluation scores correlated better with 7-day ICU-mortality when corrected Pao2/Fio2 ratio was used for classification. For patients with Fio2 less than 50% (n = 55), change in Paco2 correlated with change in Pao2/Fio2 ratio (r = -0.388; p = 0.003). A corrected Pao2/Fio2 ratio was calculated. Correcting the Pao2/Fio2 ratio for the alveolar gas equation predominantly affects patients with high ratios between Pao2 and Fio2 and Paco2 and at low atmospheric pressure. Using the corrected Pao2/Fio2 ratio for acute respiratory distress syndrome classification results in improved correlation with the 7-day ICU mortality and increases generalization among acute respiratory distress syndrome studies.

Purulent expectoration was also more frequent in this subset of patients. Admission was usually required for patients with COPD, and length of hospitalization was significantly increased; however, difference in the mortality rate was not observed.

Catheters were placed in the carotid arteries, left ventricles, and pulmonary arteries of anesthetized, ventilated (FiO2=0.5) pigs (31.2+/-0.6 kg; n=26). A unilateral, blunt injury to the right chest was delivered with a captive bolt gun (n=17) followed by tube thoracostomy. To control for anesthesia and instrumentation at FiO2 of 0.5, one group received tube thoracostomy only (sham injury; n=6). To control for effects of hypoxia without chest injury, an additional sham-injury group (n=3) was ventilated with FiO2 of 0.12. To generate cardiac function (i.e., Starling) curves, lactated Ringer's solution was administered in three bolus infusions at serial time points; the slope of stroke index versus ventricular filling pressure defines cardiac contractility. By 4 hours after pulmonary contusion, pulmonary vascular resistance, airway resistance, and dead space ventilation were increased, whereas PaO2 (72+/-6 mm Hg at FiO2=0.5) and dynamic compliance were decreased (all p &lt; 0.05). Despite profound lung injury, arterial blood pressure, heart rate, cardiac filling pressures, and output remained within the normal range, which is inconsistent with direct myocardial contusion. The slope of pulmonary capillary wedge pressure versus left ventricular end-diastolic pressure (LVEDP) regression was reduced by more than 50% from baseline (p &lt; 0.05), but there was no significant change in the slope of the central venous pressure versus LVEDP regression. By 4 hours after contusion, the slope of the stroke index versus LVEDP curve was reduced by more than 80% from baseline (p &lt; 0.05). By the same time after sham injury with FiO2 of 0.12 (PaO2 &lt; 50 mm Hg), the regression had decayed a similar amount, but there was no change in the slope after sham injury with FiO2 of 0.5 (PaO2 &gt; 200 mm Hg). After right-side pulmonary contusion, the most often used estimate of cardiac preload (pulmonary capillary wedge pressure) does not accurately estimate LVEDP, probably because of changes in the pulmonary circulation or mechanics. Central venous pressure is a better estimate of filling pressure, at least in these conditions, probably because it is not directly influenced by the pulmonary dysfunction. Also, ventricular performance can be impaired by depressed myocardial contractility and increased right ventricular afterload even with normal left ventricular afterload and preload. It is thus conceivable that occult myocardial dysfunction after pulmonary contusion could have a role in the progression to cardiorespiratory failure even without direct cardiac contusion." } ] } } }

Circumcision generally protects males from UTI, however, during the month following the procedure, the prevalence of infection increases up to 12 times in circumcised boys when compared with those not circumcised. Almost all the infections are caused by aerobic Gram-negative bacteria of which E. coli are responsible for 70-90% of the cases. Signs and symptoms of UTI vary in different age groups. Factors associated with the likelihood of UTI are: non-circumcised male, fever &gt; 40 degrees C, and a fever &gt; 39 degrees C for more than 48 hours with no other focus of infection on physical examination. Urinalysis and urine microscopy are screening tests for UTI. In children with clinical symptoms and signs suggesting UTI, the results of these tests have a positive predictive value (if both are positive), or negative predictive value (if both are negative) approximating 100%. The definitive diagnosis of UTI is based on the urine culture. Bag urine culture is associated with a very high rate of contamination. Therefore, in non-toilet trained children, urine culture should be obtained directly from the urinary bladder either by supra pubic aspiration or in and out transurethral catheterization. Mid stream clean voided urine specimens obtained from circumcised males in the first months of life are also acceptable.

Antibiotic susceptibility was evaluated. By means of CLSI criteria from 2007 to 2010, while from 2011 EUCAST criteria were adopted. Data on susceptibility to amoxicillin-clavulanate, co-trimoxazole, cefuroxime, nitrofurantoin, fosfomycin and ciprofloxacin were evaluated for Escherichia coli, while for other Enterobacteriaceae data were collected for amoxicillin-clavulanate, co-trimoxazole and ciprofloxacin and for ciprofloxacin against Pseudomonas aeruginosa. Univariate and multivariable analyses were performed for risk factors associated with resistance. A total of 4596 Gram-negative strains were observed in 3364 patients. A significant increase in the proportion of resistant strains was observed for E.coli against amoxicillin-clavulanate, cefuroxime and ciprofloxacin and for others Enterobacteriaceae against co-trimoxazole and ciprofloxacin. Resistance to nitrofurantoin and fosfomycin was very infrequent in E.coli. Logistic regression analysis showed that repeated episode of urinary tract infections was a risk factor for E.coli resistance to amoxicillin-clavulanate, co-trimoxazole and cefuroxime, while admission in one of the Units usually managing children with urinary tract malformations was significantly associated to resistance to amoxicillin-clavulanate and cefuroxime. In conclusion the present study shows an increase in antibiotic resistance in pediatric bacteria isolated from urines in children, especially in presence of repeated episodes and/or urinary tract malformations. This resistance is worrisome for beta-lactams and cotrimoxazole, and start to increase also for fluoroquinolones while nitrofurantoin and fosfomycin still could represent useful drugs for oral treatment of these infections. • Infections are frequent in patients with urinary tract malformations • Antibiotic prophylaxis can select for resistant pathogens What is New: • The increase in the resistance to β-lactams, co-trimoxazole or fluoroquinolones in pathogens causing urinary tract infections cause a reduction of drugs with oral formulations available for therapy • Old drugs like nitrofurantoin and fosfomycin can represent attractive compounds for oral treatment of urinary tract infections in children presence of resistance to other drug classes." }, { "id": "pubmed23n0845_7858", "title": "[Children less than 3 months hospitalised due to acute febrile syndrome. 5 years clinical experience].", "score": 0.009708737864077669, "content": "Acute fever of unknown origin (AFUO) is established when the anamnesis and physical examination cannot identify the cause.

A 4-year-old girl described here was hospitalized due to a productive cough over the previous 3 weeks and a fever &gt; 38 °C associated with tachypnea over the previous 2 days. Her familial and personal medical histories were negative for relevant diseases, including respiratory infections. At admission, she was febrile (axillary temperature 39.2 °C) and had dyspnea with retractions, grunting and nasal flaring.

Children can be treated effectively with short courses (2-4 days) of intravenous (IV) therapy followed by oral therapy. If IV therapy is chosen, use of once-daily dosing may allow outpatient management instead of hospital admission. However, no description of ambulatory treatment with IV antibiotics of UTI among febrile children has been reported to date. We aimed to describe the feasibility and complications of outpatient management with IV antibiotics of UTI among febrile children, at the day treatment center (DTC) of a tertiary-care pediatric hospital. Between April 1, 2002, and March 31, 2003, a prospective cohort of patients 3 months to 5 years of age who were examined in the emergency department (ED) and diagnosed as having presumed febrile UTI were treated according to a clinical protocol. Patients were treated at the DTC unless they met exclusion criteria, in which case they were hospitalized. The DTC was open 7 days per week, including holidays, from 8:30 am to 4:30 pm. At the DTC, patients were initially treated with a daily dose of IV gentamicin, until the child had been afebrile for at least 24 hours, and with oral amoxicillin, until preliminary urine culture results were available. Children allergic to penicillin received gentamicin only. IV antibiotics were administered through peripheral IV access; the IV catheter's patency was maintained with injection of 50 U of heparin once daily throughout the treatment period. Parental satisfaction with the DTC experience was assessed with an anonymous, self-administered questionnaire. Two hundred ninety-one episodes of presumed febrile UTI were diagnosed in the ED, of which 212 (72.9%) were sent to the DTC. There were 71 hospital admissions (24.4%); in 9 of these instances, the child was admitted because parents refused or were unable to comply with DTC treatment. Adherence to the treatment protocol in the ED was excellent; in 92.1% of presumed febrile UTI episodes (268 of 291 episodes), the patient was referred to the appropriate setting for treatment. In 8 instances, patients who met an exclusion criterion were sent to the DTC. They should have been hospitalized, according to the protocol. At the DTC, a final diagnosis of UTI was made in 178 of the 212 episodes (84%). Patients treated at the DTC, with a final diagnosis of UTI, had a median age of 12.0 months (range: 3-68 months), and their mean initial temperature was 39.2 degrees C (SD: 1.1 degrees C). Patients were afebrile by 24 hours in 52% of UTI episodes and by 48 hours in 82%. Minor problems with IV access occurred in 9.0% of cases. The duration of IV antibiotic therapy at the DTC was 1.9 days (SD: 0.9 day). The mean number of visits to the DTC, including appointments for renal ultrasound and voiding cystourethrography evaluations, was 3.5 (SD: 0.9). Parents were present at all scheduled visits in 98.9% of cases. Four patients needed to be hospitalized from the DTC, but in only 1 case was hospital admission related to UTI treatment. Four patients with UTI treated in the DTC had positive blood cultures, 2 with Escherichia coli (both successfully treated at the DTC) and 2 with contaminants. For 4 children treated at the DTC, UTI was caused by gentamicin-resistant E coli. One patient became afebrile within 24 hours after treatment initiation with IV gentamicin; he was then treated with oral cefixime. A second patient was treated with IV ceftriaxone, administered at the DTC once culture results were available, and remained febrile for &lt;72 hours. The last 2 patients were hospitalized; one, who was also allergic to cephalosporins, had been febrile for 72 hours at the time of hospitalization (once hospitalized, he was treated with IV amikacin), and the other was admitted to the hospital for an unrelated problem, namely, scalp cellulitis. None of these 4 patients was initially bacteremic or became bacteremic during the treatment period. Repeat urine culture was performed within 14 days after treatment initiation in 146 instances, and results were negative in all cases. At telephone follow-up assessments 14 days after discharge, no patient had been rehospitalized because of UTI. Successful treatment at the DTC (defined as attendance at all visits, normalization of temperature within 96 hours, negative control urine cultures, if performed, and absence of hospitalization from the DTC) was observed in 96.6% of the 178 UTI episodes. Overall adherence of physicians to the protocol at the DTC was 87.1% (95% confidence interval: 82.2-92.0%). One hundred seventy-two satisfaction questionnaires were returned and revealed good, very good, or excellent parental satisfaction in 98.8% of cases. Our data show that ambulatory treatment with IV antibiotics, at a DTC, may be used for at least three-fourths of UTIs among febrile children 3 months to 5 years of age. It is safe and feasible and appears very satisfactory to parents. Although ambulatory treatment with IV antibiotics is more invasive than oral therapy during the initiation of UTI treatment, it ensures almost full compliance, allows close medical supervision, and facilitates investigations related to the UTI. It is an interesting alternative to hospitalization." }, { "id": "pubmed23n0599_9102", "title": "[Evaluation of impact of CRP rapid test in management of febrile children in ambulatory pediatric practice].", "score": 0.009433962264150943, "content": "Fever without source (FWS) is a common cause of children visits to pediatric practices.

The study was undertaken in 2006-2007, in 14 pediatric practices. Pediatricians had to enroll all children, older than three months, consulting for FWS, for whom CRP was prescribed. The pediatric practices were distributed in two groups: in the first one, pediatricians had rapid CRP tests (NycoCard) CRP test, Progen Biotechnique) and in the second one, they sent children to laboratory for the dosage of CRP as usually. Between October 2006 and June 2007, 227 children were enrolled by 17 pediatricians: 159 in the group with rapid CRP test (group 1), 68 in the group without (group 2).

In most cases, the testes will descend spontaneously by 3 months of age. If the testes do not descend by 6 months of age, the probability of spontaneous descent thereafter is low. About 1%-2% of boys older than 6 months have undescended testes after their early postnatal descent.

A surgical specialist referral is recommended if descent does not occur by 6 months, undescended testis is newly diagnosed after 6 months of age, or testicular torsion is suspected. International guidelines do not recommend ultrasonography or other diagnostic imaging because they cannot add diagnostic accuracy or change treatment. Routine hormonal therapy is not recommended for undescended testis due to a lack of evidence. Orchiopexy is recommended between 6 and 18 months at the latest to protect the fertility potential and decrease the risk of malignant changes. Patients with unilateral undescended testis have an infertility rate of up to 10%. This rate is even higher in patients with bilateral undescended testes, with intra-abdominal undescended testis, or who underwent delayed orchiopexy.

The incidence is indirectly related to birth weight and dramatically decreases during the first 3 months after birth. Many nonscrotal testes are retractile and require no therapy whatsoever. True cryptorchid testes develop identifiable histologic alterations within 2 years of parturition, and endocrine abnormalities are often detectable during infancy. Hormonal therapy with hCG is effective in causing descent in only a small percent of children with cryptorchidism. GnRH nasal spray is no different from placebo in double-blind studies in which retractile testes have been excluded. The results are best in low-lying testes and in older children, but a recognized late-failure rate requires continued surveillance. HCG therapy appears to be of little use in nonpalpable cryptorchid testes. The risk of testicular cancer is increased in men with a history of cryptorchidism and even includes the contralateral descended testes. This risk may be reduced by early orchidopexy. Fertility is impaired in men with cryptorchidism and is reported to be no better than 75% and 50%, respectively, in men who have undergone successful unilateral or bilateral orchidopexy.

The parents of children with a nonpalpable testis should be informed of the high rate of testicular absence. If hormonal therapy is to be used, it must be initiated at 10 months of age.

Hormones play a pivotal role in testicular descent except during the migration to the level of internal inguinal ring. Cryptorchidism is present in about 4.5% of newborns with a higher incidence in preterms. The incidence decreases to 1.2% by the first year. It is classified as palpable and impalpable. The most common site of an ectopic testis is superficial inguinal pouch. Retractile testis is often bilateral and most common in boys between 5 and 6 years of age. Hypospadias and inguinal hernias are the most common associated anomalies seen with undescended testis. A thorough clinical examination helps in arriving at the etiology. A short hCG stimulation test helps to exclude anorchia. Different imaging techniques are of little help in diagnosis and require the help of an experienced radiologist. Laparoscopy has an important role in the diagnosis and management of undescended testis. The common complications include torsion and atrophy of testis. Infertility is seen in about 40% of unilateral and 70% of bilateral cryptorchidism. Undescended testis is 20 to 40 times more likely to undergo malignant transformation than normal testis. Both hCG and GnRH have been used with limited success in these children. All boys with cryptorchidism should be referred to a pediatric surgeon before 2 years of age.

This paper is based on selected findings from a MEDLINE search on undescended testes and orchiopexy referrals, and on our experience at the Urology Clinic at the Children's Hospital of Eastern Ontario in Ottawa, including review of referrals to our clinic for undescended testes and the resultant findings of normal variants versus surgical cases. The MeSH headings used in our MEDLINE search included <iundescended testicle, retractile testicle, ectopic testicle, ascended testicle, referral and consultation,</i and <iorchiopexy</i. An <iundescended testis</i is defined as the true absence of one testis (or both testes) from normal scrotal position. Ectopic and ascended testes will likewise be absent from the scrotum, the latter having been present at one point in development. Differentiating among testicular examination findings is important, as descended and retractile testes are managed conservatively, while prompt surgical intervention should be offered for ascended, ectopic, and undescended testes. Uncertainty surrounding the diagnosis of an undescended testis causes anxiety, might lead to unwarranted imaging, and might increase the wait list for specialty assessment. For this reason, avoidance of ultrasound in the evaluation of undescended testes was included in the recent Choosing Wisely Canada campaign. We seek to clarify the physical examination findings in the evaluation of possible undescended testes, the suggested referral parameters, and the subsequent management. Undescended testes and their variants are common. As decision for referral is based on the primary care physician's physical examination findings, we clarify distinguishing between normal and abnormal findings on testicular examination to aid in appropriate referral for subspecialist evaluation. Consultation, if needed, should be sought at 6 months' corrected gestational age, or at detection if later than 6 months, without delay for ultrasound imaging, as surgical management is recommended for those patients with undescended, ectopic, or ascended testes." }, { "id": "pubmed23n0085_20490", "title": "[Treatment of an undescended testis with human chorionic gonadotropin (HCG)].", "score": 0.01335978835978836, "content": "Seventy one patients with ectopic testis of age between 2 and 11.5 years were treated with human chorionic gonadotropin (HCG) at doses recommended by the International Health Foundation.

The degree of visual field defects in eyes with the disease varied greatly with mean deviation of -10 dB or less in as many as 10% of the subjects. Although retinitis pigmentosa is a diffuse retinal dystrophy, eyes with a moderately advanced stage of retinitis pigmentosa should be managed as a macular disease, because the functioning retina is confined within the vascular arcade. The progressive nature in this stage of the disease could be demonstrated with a central 10-degree automated static perimetry measured once or twice a year and the use of univariate linear regression of mean deviation, in half of the patients with a mean follow-up period of 5 years. Functional recovery in eyes with exudative age-related macular degeneration after laser surgery or submacular surgery could be evaluated with central 10-degree automated static perimetry. Eyes with increased mean deviation in spite of reduced visual acuity after therapeutic intervention should also be evaluated. Macular function could also be evaluated using a color test. A newly developed color saturation discrimination test was applied to patients with age-related macular degeneration, retinitis pigmentosa, and cone dystrophy. The degree of dyschromatopsia was less in eyes with age-related macular degeneration than in those with retinitis pigmentosa or cone dystrophy with the same level of acuity loss. The highly protrusive nature of the orange-red nodule in eyes with idiopathic polypoidal choroidal vasculopathy was demonstrated with dimensional measurement with OCT. The degree of protrusion was greater than in eyes with serous pigment epithelial detachment, which suggests that the polypoidal lesion is covered with rigid tissues including Bruch's membrane. Parafoveal retinal sensitivity obtained with automated static perimetry was studied in correlation with retinal thickness measured using OCT in eyes with branch retinal vein occlusion showing macular edema without macular non-perfusion or massive retinal hemorrhages. The increased retinal thickness due to macular edema is closely correlated with retinal sensitivity both at the fovea and in the parafoveal area. Eighty-nine phakic eyes of 46 patients with retinitis pigmentosa patients were studied to detect cystoid macular edema using OCT. Cystoid lesions were observed in the macula in 12 eyes in 6 (13%) of 46 patients. Some eyes with OCT-proven cystoid macular edema did not show dye pooling in the fluorescein angiogram.

For example, we often observe choroidal neovascularization (CNV) in elderly patients without drusen in the fundus. The high incidence of polypoidal choroidal vasculopathy (PCV) in AMD among Japanese is well-known. The reason why such differences occur in clinical manifestations of AMD has been one of my main interests. In this review article, I will discuss the characteristics of AMD in the Japanese population, as found in our recent study. I. Prevalence and clinical characteristics of AMD in the Japanese population. Cohort studies are important to determine the prevalence and incidence of diseases. In Japan, cohort studies began to be carried out rather late compared with Western countries. Although good cohort studies from Japan are reported in the literature, the size of the cohorts was not sufficiently large to determine the prevalence of AMD. However, a recent meta-analysis of Asian cohorts has shown that the prevalence of late AMD in Asians is not different from that reported in Caucasians. On the other hand, the prevalence of early AMD appears lower in the Japanese than in Caucasians. Recently, we have published the results of the Nagahama Cohort study. In this cohort study, we found a high prevalence of drusen. It seems that the incidence of dry AMD is likely to increase among Japanese. In Japan, most retina specialists classify AMD into three categories : typical AMD, PCV, and retinal angiomatous proliferation (RAP). However, there are no definite diagnostic criteria to distinguish between the three conditions. To compare the clinical features of Japanese and Western cases of AMD, and to determine the incidence of the three types of AMD, we exchanged data about 100 consecutive cases between Kyoto University and Centre d'Ophtalmologie de Paris, France. Interestingly, the diagnoses made by the two institutes were not always in agreement. We also found more cases of PCV among the Japanese than among the French. II. PCV. About 50% of exudative AMD cases in the Japanese population are PCV. Because of its peculiar angiographic findings, PCV has long been considered to be a distinct clinical entity different from the usual exudative AMD. Also, there have been serious discussions on the nature of PCV. In our analyses, about 20% of PCV cases show rather large lesion sizes that exceed the vascular arcade. Scar formation in the macula and compromised vision are frequent findings in such cases. The occurrence of PCV in the inferior staphyloma or in angioid streaks shows heterogeneity in PCV. These findings suggest that PCV may be a finding on indocyanine green angiography rather than a distinct clinical entity. Spectral domain OCT examination shows that the branching vascular network of PCV is located between the retinal pigment epithelium and Bruch's membrane. In cases with retinal pigment epithelial detachment, CNV from the branching vascular network was found to extend along the roof of the detached retinal pigment epithelium. Such findings show that the branching vascular network of PCV is type 1 CNV. Complement factor H (CFH) and age-related maculopathy 2 (ARMS2)/High temperature requirement 1 (HTRA1) located on chromosome 10 (10q26) are well-established disease susceptible genes of AMD. In the Japanese, the prevalence of CFH Y402H gene polymorphism is low and ARMS2/HITRA1 plays a more important role in the development of AMD. In ARMS2 A69S polymorphism, a large deletion/insertion (443de1/54ins) that is reported in Caucasians was also found in Japanese. Thus, the genetic background of Caucasian and Japanese AMD is quite similar, as is also the case with exudative AMD and PCV. Our findings show that PCV is not a distinct clinical entity but is a subtype of exudative AMD. III. Exudative AMD with choroidal vascular hyperpermeability. Choroidal vascular hyperpermeability observed in central serous chorioretinopathy can be found in about 20% to 30% of exudative AMD cases in Japanese. Such cases often show a thick choroid, lack of drusen, and rather good visual prognosis with slow progression of the disease. Recently, \"pachychoroid neovasculopathy\" has been described by a group from New York. Such cases of AMD with choroidal vascular hyperpermeability, a thick choroid, and lack of drusen appears to belong to pachychoroid neovasculopathy. We studied the risk allele frequencies of CFH I62V and ARMS2 A69S gene polymorphisms in three groups : usual exudative AMD, pachychoroid neovasculopathy, and normal controls. Interestingly, cases of pachychoroid neovasculopathy show different gene polymorphisms of CFH I62V and ARMS2 A69S from the usual cases of exudative AMD and a more similar pattern to normal controls. Therefore, the possible mechanisms of the CNV development in such cases may differ from the classic well-documented drusen-dependent pathways. IV. Atrophic AMD in Japanese. Data from the Nagahama Cohort study show an increasing prevalence of drusen in Japanese. Recently, more extensive information on drusen has become available and the redefinition of drusen is currently in progress. In particular, the importance of reticular pseudodrusen (RPD) is more widely appreciated. This type of drusen is often found in Japanese AMD. Although the nature and location of RPD are still debatable, many investigators believe that this type of drusen is located under the sensory retina rather than under Bruch's membrane. In our analyses, RPD was found in 18.4% of late AMD cases in Japanese. It was more common in eyes with RAP or atrophic AMD and was seldom found in PCV. ARMS2 A69S gene polymorphism was found more frequently in cases of exudative AMD with RPD, than in cases of exudative AMD without RPD. Eyes with RPD show a thin choroid and diminished vascular densities of choroidal vessels." }, { "id": "pubmed23n0867_10837", "title": "[Humphrey Perimetry and Retinal Diseases].", "score": 0.010557691236280572, "content": "Since, in most eyes with retinal diseases quality of vision is greatly affected by visual field defects including paracentral scotoma and inferior field defects, visual function should be assessed by central 30- or 10-degrree automated static perimetry as well as visual acuity testing. The reduction of light sensitivity, demonstrated in the results of Humphrey central 10-2 perimetry, is more apparent than visual acuity loss in eyes with central serous chorioretinopathy (CSC), in which patients complain of dimness in the visual field of the affected eye. While reduced light sensitivity in eyes with acute CSC is well correlated with the height of subretinal fluid, marked and irreversible light sensitivity loss is demonstrated in the absence of subretinal fluid in eyes with chronic CSC due to structural damage in the photoreceptors. Various degrees of light sensitivity loss are seen in eyes wih age-related macular degeneration corresponding to intraretinal or subretinal pathology including intra- or subretinal fluid, fibrous scarring containing choroidal neovascularization and atrophic changes. The mean deviation (MD) of Humphrey central 10-2 perimetry is useful in predicting the visual outcome in eyes with exudative AMD after photodynamic therapy or intravitreal injection of anti-vascular endothelial growth factor. The progression of retinitis pigmentosa is well assssed with MD of Humphrey central 10-2 perimetry, which decreases linearly in the stage of residual visual field of 10 degrees or less. The age of patients with visual loss below 0.5 is delayed in eyes showing pencil-like configuration of \"Traquair's island of visual field\", in which a small area of normal light sensitivity around the fixation point is surrounded by absolute scotoma. With less visual acuity loss compared with that seen in eyes with central retinal artery occlusion; eyes with branch retinal artery occlusion show marked visual field defects, which are permanent and profound simulating the nasal-step pattern seen in eyes with glaucoma. Non-perfusion areas in fluorescein angiograms of eyes with branch retinal vein occlusion generally demonstrate reduced light sensitivity in the results of Humphrey central 30-2 perimetry, the degree of which tends to correlate with severity of non-perfusion.

However, little or no recovery occurs when the loss is caused by atypical ON, especially in patients with neuromyelitis optica (NMO). Optic disc drusen (ODD) is a cause of pseudo optic disc edema and may be a predisposing factor for non-arteritic anterior ischemic optic neuropathy (NAION), thereby mimicking atypical ON. In such cases, if globular concretions are seen protruding from the disc substance, ODD may be suspected. The purpose of this paper is to describe two patients with acute visual loss followed by optic disc atrophy initially labeled as atypical ON. Though not suspected on clinical examination, optical coherence tomography (OCT) revealed deeply buried ODD as a predisposing factor for NAION. Case 1: A 48-year-old woman had bilateral sequential visual loss associated with optic disc edema. Despite treatment, vision did not improve and severe disc pallor ensued. Atypical ON was suspected. Eventually, she was started on immunosuppressant therapy based on a tentative diagnosis of NMO-spectrum disorder. On examination 5 years later, only severe optic disc pallor was observed, but OCT radial B-scans showed ovoid hyporeflective areas in the retrolaminar region of both eyes, compatible with ODD; this led to a diagnosis of NAION and deeply buried ODD. Case 2. A 35-year-old woman with suspicion of ON in the left eye and a history of previous atypical ON in the right eye was referred for neuro-ophthalmic examination which revealed diffuse optic disc pallor and a dense arcuate visual field defect in the right eye. OCT B-scans passing through the disc showed large ovoid areas of reduced reflectivity in the retrolaminar region of the optic disc in the right eye. These findings helped confirm the diagnosis of NAION in one eye, with deeply buried ODD as predisposing factor. Deeply buried ODD may be associated with NAION causing irreversible visual loss and optic disc pallor, a condition easily mistaken for atypical ON.

In all the cases of fractures of the mandibular condyle an acute alteration of the junctional atlanto-axial structures was present.

In case of unilateral condylar fractures associated with other mandibular fracture (homolateral or not) the authors have observed the same alterations of the occipital-atlo-epistropheal joint, but while on the horizontal plane the rotation of the atlas is always homolateral to the condylar fracture, on the vertical plane the largest atlanto-axial articular space is homolateral to the mandibular fracture with more dislocation of the fragments of fracture (usually the associated not homolateral mandibular fracture). In case of bilateral condylar fractures the authors have observed no alteration of the cranio-cervical joint. In the non-equivalent fractures, they have observed the atlas rotation on the horizontal plane and the junctional derangement on the vertical plane, homolateral to the condylar fracture with greatest dislocation.

The maxillofacial region is one of the most complex areas of the human body, and the radiographic imaging of this region becomes even more difficult in traumatized patients because of their clinical condition and their inability to cooperate. Imaging modalities used in the evaluation of the traumatized maxillofacial region include conventional (plain) films, tomography, panoramic radiography, computed tomography, three-dimensional computed tomography, DentaScan, and magnetic resonance imaging. Each modality is discussed with regard to technique, advantages, and disadvantages. Plain films and computed tomography, the modalities that are used most in evaluating maxillofacial structures, are discussed in more detail. The normal anatomy and radiologic features are presented for both of these modalities. Radiographic evaluation of maxillofacial injury begins with a knowledge of the direct and indirect radiographic signs of injury seen on most imaging modalities. Computed tomography also has allowed a method of classifying facial fractures that is based on the involvement of the facial buttresses or struts. Three horizontal, two coronal, and five sagittal oriented struts are described. Limited fractures are differentiated from transfacial fractures by the lack of involvement of the pterygoid plates in the limited fractures. Limited fractures also can be subclassified as solitary (fracture of a single strut) or complex (fractures of multiple struts). A portion of the orbit is involved in almost every form of facial fracture; therefore, evaluation of facial injuries should always include the orbital structures. Although both can occur simultaneously, orbital injuries can be divided into soft tissue and bony vault injuries. Similar to midface fractures, orbital fractures also can be classified as solitary (fracture involves a single wall) or complex (fracture involves more than one wall or a part of a midface fracture). Computed tomography is of great value in evaluating both forms of injury. Magnetic resonance imaging is becoming increasingly important in the evaluation of orbital soft tissue injuries. Classification of midface injuries includes the solitary strut fractures and the complex strut fractures. Solitary strut fractures include fractures of the nasal arch, zygomatic arch, and isolated sinus wall fractures.

This question could be controversial. Option 1 is strongly discarded because endophthalmitis typically presents with a lot of pain. Option 3 of wet form of age-related macular degeneration is also ruled out, because it usually occurs in older patients, although what a patient with myopia magna may present with is myopic macular degeneration (with a similar clinical picture to AMD, but this is a different pathology). A posterior vitreous detachment (PVD) is usually not very symptomatic, producing myodesopsias but no loss of vision or pain; however, some PVDs are of the hemorrhagic type, by traction of the vessels, producing a vitreous hemorrhage that would cause loss of vision. In any case, due to the history of myopia magna and previous intraocular surgery, the first diagnosis to rule out would be retinal detachment, since these are two risk factors for this pathology.

Patients and surgeons may not associate late complications with the initial surgery. However, recent studies have demonstrated that such a causal relationship may persist for many years after the cataract procedure and that there is a significant increase in the risk for developing a retinal detachment during the postoperative years. The mean time period between cataract surgery and pseudophakic retinal detachment is between 3 and 4 years. Even uncomplicated cataract surgery alters the physiological processes within the eye and can lead to progressive destruction of the vitreous for many years after the surgery. Therefore, the risk for a retinal detachment is increased for at least 10 years after the initial procedure. In recent epidemiological studies, the most important risk factors for pseudophakic retinal detachment were myopia, younger age and male gender. If all factors are combined, the cumulative risk for developing a retinal detachment after cataract surgery may rise to 20 %. Additional factors that may increase this risk are additional intraoperative complications, for example, rupture of the posterior capsule, vitreous loss or dropped nucleus. Compared to phakic retinal detachments, pseudophakic patients on average present with a shorter history of visual symptoms, are older, more commonly male and display fewer, smaller and more anteriorly located retinal breaks that frequently are only detected during surgery. The anatomic success rates have improved significantly over the past years, in particular through the advances and increasing popularity of primary vitrectomy. However, functional results are still disappointing. Only about half of the patients will achieve reading ability without low vision aids. The increased and long-term risk for pseudophakic retinal detachment should be part of the preoperative consent process of any cataract surgery, in particular, in young myopic males." }, { "id": "wiki20220301en059_60326", "title": "Posterior vitreous detachment", "score": 0.013674798721527694, "content": "Age and refractive error play a role in determining the onset of PVD in a healthy person.

Both eyes with the retinal detachment were re-operated. In both of them, the repeated pars plana vitrectomy, epiretinal membranes removal with relaxing retinectomy was performed and after maximal mobilization of the retina, the silicone oil implantation followed.

Rhegmatogenous retinal detachment typically presents with the perception of light flashes, floaters, or a \"dark curtain.\" In most cases, the retinal tear is a consequence of degeneration of the vitreous body. Epidemiologic studies have identified myopia and prior cataract surgery as the main risk factors. Persons in the sixth and seventh decades of life are most commonly affected. Rhegmatogenous retinal detachment is an emergency, and all patients should be seen by an ophthalmologist on the same day that symptoms arise. The treatment consists of scleral buckle, removal of the vitreous body (vitrectomy), or a combination of the two. Anatomical success rates are in the range of 85% to 90%. Vitrectomy is followed by lens opacification in more than 70% of cases. The earlier the patient is seen by an ophthalmologist, the greater the chance that the macula is still attached, so that visual acuity can be preserved. Rhegmatogenous retinal detachment is among the main emergency indications in ophthalmology.

Patients were divided into two groups (the RD group and non-RD group) depending on the presence of RD or not. Their clinical data and optic coherence tomography (OCT) results were further analyzed. SPSS 13.0 was used for the statistic analysis. When comparing the quantitative aspects like age, axial length and refraction, t-test was used. Categorical data, such as sex ratio, occurrence of vitreous traction, posterior staphyloma and retinoschisis were compared by using χ(2) test. Fisher's test was used in comparing eye laterality, incidence of white hole, visual acuity and posterior vitreous detachment (PVD).

In this case, the presence of thickening of the subepithelial collagen layer, more evident with Masson's trichrome (special stain that allows differentiation of the collagen fibers), is pathognomonic of collagenous colitis. Atrophy together with epithelial denudation are characteristic of this disease, which does not usually cause macroscopic alterations of the mucosa. An increased density of intraepithelial lymphocytes and the absence of mention of architectural alterations of the crypts (characteristic of ulcerative colitis and Crohn's disease) support this diagnosis.

In the present view, MC is an inflammatory bowel disease of unknown etiology, which is characterized by chronic watery diarrhea, no macroscopic signs of large bowel involvement in the presence of specific pathomorphological changes. There are two major forms of MC, which are similar in its clinical picture, yet, heterogeneous in histological criteria: collagenous colitis (CC) and lymphocytic colitis (LC). As of now, the prevalence of MC is about 100 cases per 100,000 population, which is similar with that in other inflammatory bowel diseases, such as ulcerative colitis and Crohn's disease. MC generally prevails in women aged over 50 years. The etiology and pathogenesis of MC have not fully investigated. Watery diarrhea is as a predominant pathognomonic symptom in all the patients with MC. The major histological criterion for the diagnosis of CC is subepithelial collagen lining thickening (more than 10 pm) and that for LC is higher intraepithelial lymphocyte counts (more than 20 intraepithelial lymphocytes/100 epitheliocytes).

The intraepithelial lymphocytes, villous atrophy and thickness of the subepithelial collagen were also determined in gastric and duodenal biopsies. In collagenous colitis, the subepithelial collagenous thickness ranged from 10 to 40 microns in the colon (median 20.99 microns). In 4 cases of collagenous colitis, no thickening of the collagen plate was seen in the rectum. We found constant epithelial detachment and mucosal distortion. In lymphocytic colitis, the thickness of the subepithelial collagen ranged from 6 to 10 microns in 4 cases and was less than 6 microns in 3 cases (median 6.24 microns).

Twenty two (22) colon biopsies with the most severe histological lesions were selected. These biopsies were obtained from 17 patients: 5 patients had 2 biopsies in 2 colonoscopy sessions. Biopsies were fixed in neutral formaldehyde, processed through the paraffin inclusion method, and stained with hematoxiline-eosine and Masson trichromic to distinguish collagenous tissue. Immunohistochemistry was conducted in 4- or 5-micron-thick histological sections processed through the immunoperoxidase method. Nineteen (19) biopsies corresponded to Lymphocytic MC and 3 to Collagenous MC. Lymphocytic MC showed intraepithelial lymphocytosis, dystrophic epithelial damage in the areas of lymphocytic infiltration, lamina propria inflammation with lymphocytes and plasma cells, and normal basement membrane. Collagenous MC showed thickened basement membrane due to the presence of a collagenous band, mild to moderate intraepithelial lymphocytosis, vacuolization,and frequent detachment of protective epithelium.

Simply quantitating the thickness of a subepithelial collagen layer is neither adequate nor necessary for the diagnosis of collagenous colitis. Major problems in diagnosing collagenous colitis arise from focusing solely on the subepithelial region without attention to inflammatory changes. For example, tangential sectioning of normal colon results in an artifactually thickened basement membrane, and such cases have been wrongly interpreted as collagenous colitis.

With collagenous colitis, the major microscopic characteristic is a thickened collagen layer beneath the colonic mucosa, and with lymphocytic colitis, an increased number of intraepithelial lymphocytes. Histological workup can confirm a diagnosis of MC and distinguish the two distinct histological forms, namely, collagenous and lymphocytic colitis. Presently, both forms are diagnosed and treated in the same way; thus, the description of the two forms is not of clinical value although this may change in the future.

Microscopic colitis is an anatomo-clinic syndrome characterized by the presence of histological abnormalities on colic biopsies amongst patients suffering from chronic watery diarrhoea without endoscopic anomalies. Two clinical entities are today well known: collagenous colitis is characterized by a thickening of the sub-epithelial collagen band of the colon; lymphocytic colitis is defined as an increased level of lymphocytic cells, more than 20%, in the epithelial surface of colorectal mucosa. Inflammatory lesions of the chorion and alterations of the epithelial surface are seen in the two types of colitis. Their etiology remains unknown. It could be due to inflammatory lesions from autoimmune origin, activated by various exogenous agents such as bacteria and drugs. Clinical (feminine prevalence, frequent association with auto-immune diseases) and morphological similarities lead to argue and to hypothesis that both entities could represent different stages of the same disease, the lymphocytic colitis being the early stage.

The idea of \"hospital acquired disease\" although vague, included five infective nosologic entities, which at that time were diagnosed more frequently: erysipelas, tetan, pyemia, septicemia, and gangrene. Nonetheless, the suppuration with pus production was considered from most of the surgeons and doctors of that time as a necessary and unavoidable step in the process of wound healing. During the end of the eighteenth century, hospitals of the main European cities were transforming into aggregations of several wards, where the high concentration of patients created poor sanitary conditions and a consistent increase of perioperatory mortality. In 1865, Lister applied his first antiseptic dressing on the surface of an exposed fracture. These experimental attempts lead to an effective reduction of wound infections respect to the dressing with strings used previously. Lister's innovations in the field of wound treatment were based on two brand new concepts: germs causing rot were ubiquitarious and the wound infection was not a normal step in the process of wound healing. The concept of antisepsis was hardly accepted in the European surgical world: \"Of all countries, Italy is the most indifferent and uninterested in experimenting this method, which has been so favorably judged from the greatest surgical societies in Germany\". This quotation from the young surgeon Giuseppe Ruggi (1844-1925) from Bologna comes from his article where he presented his first experiences on aseptic medications started the previous year in the Surgical Department of Maggiore Hospital in Bologna. In his report, Ruggi described the adopted technique and suggested that the medication should be extended to all the surgical patients of the hospital:\"… this is needed to totally remove from the hospital all those elements of infection which grow in the wounds dressed with the old method\". The experimentation of this new dressing for the few treated cases was rigorous and concerned both the sterilization of surgical tools with the fenic acid (5%) and the shaving of the skin. Ruggi also observed that there was no correlation between the seriousness of the wound and its extension or way of healing: when \"simple\" cases that \"should heal without complication\" showed fever he often realized that \"it was often due to a medication performed without following the rules for an accurate disinfection and dressing\". Ruggi thought that the fever was connected to \"reabsorption of pyrogenic substances, which can be removed cleaning and disinfecting the wound\" in cases of wounds not accurately dressed and rarely medicated. Frequent postoperative medications of the wound were able to eliminate the fever within 2 h. Ruggi's attitude toward the fine reasoning lead him to introduce the concept of immunodeficiency related to physical deterioration: \"… patients treated for surgical disease may sometimes suffer from complications of medical conditions, which initially escape the most accurate investigations… The surgical operation could, in some cases, hold the balance of power\". The obtained results, published in 1879, appear extremely interesting. As he wrote in 1898, for the presentation of his case record of more than 1000 laparotomies, he had started \"… operating as a young surgeon without any tutor, helped only by his mind and what he could deduce from publications existing at the moment …\"." }, { "id": "pubmed23n0231_5685", "title": "Results of treatment of patients with severe tetanus.

He presented 7 weeks post sigmoid colectomy with lymph node resection and was initiated on adjuvant chemotherapy with CAPOX (capecitabine [Xeloda] and oxaliplatin [Eloxatin]). Standard dosing was used: oxaliplatin at 130 mg/m(2) on day 1 and capecitabine at approximately 2,000 mg/m(2)/day (rounded to the nearest 500-mg tablet size) for 14 days on and 7 days off (1 cycle = 21 days). A capped body surface area of 2.4 m2 was used, due to the patient's body habitus. Adverse Effects  Mr. D. did not report any complications of therapy during cycle 1, days 1-7, other than grade 1 diarrhea, which was amenable to diphenoxylate/atropine when taken. The next week, he reported significant malaise and fatigue associated with persistent diarrhea occurring every 30 minutes for 5 days. Mr. D. was instructed to go to the emergency room for an immediate evaluation, but he refused. Mr. D. presented to the clinic in poor condition on day 14 of cycle 1. His diarrhea had increased to grade 3 and was not controlled with either loperamide or diphenoxylate/atropine, though he was not taking his medications as directed. He had been instructed to take two 2-mg loperamide tablets after the first loose stool, followed by 1 tablet of diphenoxylate/atropine 2 hours later. He could then alternate this with loperamide every 2 hours as needed, not to exceed 8 tablets of loperamide per day. Instead, he had taken 2 tablets of loperamide after the first loose stool, but either waited 6 hours to take 1 tablet of diphenoxylate/atropine or otherwise chose not to alternate the medications at all despite continued diarrhea, depending on the day. Mr. D.'s timing in taking his supportive medications was inconsistent, and his explanations of this timing were not exact. He also reported persistent grade 3 nausea with vomiting for 5 days, which did not improve with ondansetron and prochlorperazine, though he again did not take these consistently. He was advised to alternate ondansetron and prochlorperazine every 4 hours as needed, but only took one or the other medication approximately 3 times per day. According to Mr. D., his adverse effects initially began on day 9 of cycle 1. He had lost approximately 14 kg (31 lb) during cycle 1. Clinically, he was found to have grade 2 mucositis and grade 1 hand-foot syndrome. At the time of this visit, his absolute neutrophil count was 3,000/ìL, his hemoglobin was 14.4 g/dL, his hematocrit 42.2%, and his platelet count was 139,000/ìL. His kidney function was within the normal range. Mr. D. refused hospitalization despite the primary team's recommendation. He also refused to undergo stool sampling for Clostridium difficile. He was given IV fluids along with adjustments in supportive medications, including a prescription for 10% tincture of opium. He was instructed to use 0.6 mL every 6 hours in addition to alternating loperamide with diphenoxylate/atropine as noted previously. He was advised to rinse his mouth with a baking soda solution for relief of his grade 1 mucositis, and alternation of antiemetics every 4 hours was reiterated. He was to return prior to initiation of cycle 2 for further evaluation. Worsening Symptoms  The next day, Mr. D.'s wife called the clinic to report that her husband's diarrhea continued despite the use of tincture of opium and that it was associated with hematochezia. He was also experiencing a worsening of his mucositis, with an associated swelling of the tongue. He was instructed to present to the emergency center, which he did on day 16 of cycle 1. By then, he was found to be febrile at 39.5°C. He was tachycardic, with a heart rate of 126, and he was experiencing significant abdominal pain associated with the diarrhea. The mucositis was worsening, with new odynophagia. At this time, Mr. D.'s absolute neutrophil count had dropped dramatically to 160/ìL, his hemoglobin was 13.1 g/dL, his hematocrit was 39.2%, and his platelet count was 68,000/ìL. He was admitted to the inpatient service and started on empiric antibiotics. His blood cultures remained negative during hospitalization, but stool cultures were positive for C. difficile. His antimicrobial regimen was deescalated to oral vancomycin once his stool volume decreased. He was treated with an institutional compounded mouthwash of diphenhydramine, aluminum/magnesium hydroxide, and viscous lidocaine for the mucositis, which also slowly improved. He was given a dose of growth factor. Neutropenia eventually resolved, with an absolute neutrophil count of 4,820/ìL on the day of discharge.

We also surveyed the present clinical conditions for prophylactic antibiotic use in the plastic surgery departments of training hospitals in Korea. A total of 360 consecutive patients who underwent clean wound surgery under local anesthesia in an outpatient clinic from March 2018 to October 2018 were reviewed. In the study group, a single surgeon administered first-generation cephalosporins intravenously within 1 hour of skin incision and did not prescribe additional antibiotics. In the control group, 2 other surgeons prescribed oral first-generation cephalosporins postoperatively for 2 to 3 days without preoperative antibiotics. A telephone survey about perioperative antibiotic regimens was conducted at the departments of plastic surgery in training hospitals. There were 128 patients in the study group and 232 patients in the control group. There were no significant differences between the 2 groups regarding SSIs and other surgical complications. A total of 41 training hospitals answered the survey and every hospital had protocols of prescribing postoperative oral antibiotics routinely at the time of discharge with a mean duration of 3.9 days. Only 11 hospitals (26.8%) prescribed parenteral antibiotics before surgery as well as postoperative oral antibiotics. Intravenous injection of single-dose first-generation cephalosporins 1 hour before surgery without postoperative antibiotics did not increase the incidence of SSIs compared with the usual practice of giving only postoperative antibiotics prescription for 2 to 3 days in cases of clean wound surgery performed under local anesthesia.

Local findings were a swollen left middle finger, a red-livid discoloration along his nail rim with paleness of the surrounding skin. Vital signs were stable, ECG showed sinus rhythm, laboratory parameters were normal, without signs of liver or kidney damage and without coagulopathy. Diagnosis was local tissue reaction due to a snake bite of a sidewinder rattlesnake without evidence of systemic toxic effect. Due to the absence of systemic toxic effects the patient received monitoring of his vital signs and we controlled local tissue reaction constantly and laboratory parameters every 6 hours, as recommended by the \"Giftnotrufzentrale\" (poison emergency advisory service). The patient left hospital on his own will against medical advice in the night after first laboratory control, which showed no signs of organ damage and we recommended reasessment the following morning. At that time the swelling had extended to the whole arm, furthermore large hematoma reaching up to the axilla had developed over night. Again we contacted the \"Giftnotrufzentrale\" and decided to begin the administration of an antivenom, after allergic testing. The administration was without complications, the swelling decreased constantly and since laboratory controll still showed no signs of systemic toxin effect, we could discharge the patient on day 3. Follow-up visit 6 months later showed complete and natural healing. Snake bites are altogether rare among our patients, nevertheless since possible toxin effects and its dynamics are unpredictable and can vary highly, they demand monitoring at close intervals of vitals signs, local swelling and laboratory parameters. As early as possible an advisory service, such as \"Giftnotrufzentrale\" should be contacted to acquire information on possible toxin effects and availability of antivenoms. Contact to other medical disciplines (e.g. dermatology, intensive care unit, surgery, neurology, dialysis…) should be sought, depending on the further course of toxin effects. Possible comorbidities as well as allergisation due to previous bites strongly influence the course of the disease and should be evaluated. We recommend to keep precise records on the ocurrence of systemic toxin effects, as well as on local findings (e.g. fotodocumentation, marking of erythema, measurement of swelling).

According to the Chinese emergency medicine for snakebite and the Chinese snake, the diagnostic criteria for venomous snakebite of Trimeresurus stejnegeri in Guangxi were formulated: (1) the responsible venomous snake was identified as Trimeresurus stejnegeri in Guangxi; (2) the appearance and morphology of the venomous snake described by the patient basically conformed to the characteristics of Trimeresurus stejnegeri in Guangxi; (3) clinical manifestations of hematotoxin included local swelling, severe wound pain, and subcutaneous ecchymosis in some patients; having (1) or both (2) and (3) could be diagnosed. The patients with venomous snakebite of Trimeresurus stejnegeri in Guangxi admitted to Snake Injury Treatment Base in Central and Northern Guangxi/Liuzhou Integrated Chinese and Western Medicine Snake Injury Treatment Center from January 2016 to January 2020 were enrolled. The patients were divided into the general treatment group and the covered VSD technology group, with 60 patients in each group. The general treatment group was treated with antivenom, anti-tetanus, closed injection around the wound, anti-inflammatory, magnesium sulfate gauze applied on the affected limb, symptomatic support treatment. The covered VSD technique was used in the covered VSD technology group based on the treatment options of the general treatment group. Treatment cycle of both groups were calculated from the next day of admission and lasted for 7 days. In the treatment cycle, blood was collected at 08:00 every day. The red blood cell count (RBC) and hemoglobin (Hb) were detected by automatic blood cell analyzer. The prothrombin time (PT), activated partial thromboplastin time (APTT) and fibrinogen (Fib) were detected by automatic blood coagulation analyzer, and the affected limb swelling degree and the appearance of subcutaneous ecchymosis were recorded. At different time points in the treatment cycle, the dynamic change trends of PT, APTT and Fib in the covered VSD technology group and the general treatment group were significantly different. Fib in both groups decreased on the 1-4 days, and gradually rose on the 5th day, and the lowest Fib value in the covered VSD technology group on the 4th day was higher than that in the general treatment group (g/L: 0.70±0.03 vs. 0.41±0.01, P &lt; 0.05). In the treatment cycle, PT of both groups increased in the early and middle stage, but decreased in the later stage. The peak value of PT of the covered VSD technology group on the 5th day was significantly lower than that of the general treatment group (s: 25.2±0.1 vs. 35.4±0.2, P &lt; 0.05), and the PT of the covered VSD technology group returned to the normal range on the 7th day, while the PT of the general treatment group was still abnormal. APTT in both groups increased at the beginning of the treatment cycle and gradually decreased. The peak value of APTT of the covered VSD technology group on the 3th day was lower than that in the general treatment group (s: 47.3±0.1 vs. 55.7±0.2, P &lt; 0.05), and the rate of increase and decline was also more gradual than that in the general treatment group. There was no significant difference in RBC or Hb between the two groups. With the passage of time, the degree of affected limb swelling was relieved to different degrees in both groups, and the remission degree in the covered VSD technology group was more obvious than that in the general treatment group, and there was significant difference between the two groups (χ <sup2</sup = 86.060, P = 0.000).

The application of covered VSD technology to the venomous snakebite of Trimeresurus stejnegeri in Guangxi does not aggravate the bleeding.

INFLUENCE ON THE HEALING OF WOUNDS OF VARIATIONS IN THE OSMOTIC TENSION OF THE DRESSING.", "score": 0.009009009009009009, "content": "In the study of the action of non-antiseptic substances on the rate of cicatrization, the chief obstacle encountered is the facility with which wounds become reinfected under an aseptic dressing. At the beginning of Experiment 1 the wound was sterile. It was subjected to flushing with distilled water for 2 hours, then to flushing with 30 per cent sodium chloride solution for another 2 hours. During that time no special precaution was taken to sterilize the wound and the dressing was left intact until the following morning. It was then found that the wound contained from 30 to 50 bacteria per field. The following day, after the wound had been subjected to the same treatment, the number of bacteria had increased to 50 and 100 per field, and as an immediate consequence the surface of the wound increased from 12 to 12.6 sq. cm. in 2 days. The wound was then dressed antiseptically and was found to be sterile 3 days later. Reinfection again took place the following day in spite of antiseptic dressing with chloramine paste 4 parts per 1,000, which was applied for 20 hours. In Experiment 2 similar results were observed. After 2 days of flushing with distilled water, the number of bacteria had increased to 50 per field. The wound was thereupon sterilized, but new reinfection ensued a few days later. Another wound on the same patient became reinfected under the same conditions after 1 day of sterile dressing. In none of the patients could the wounds be kept in a sterile condition throughout the whole experiment. It was impossible to maintain the sterility of a wound under aseptic dressing. Dakin's solution was therefore injected every 4 hours, or less often, according to the degree of infection, or chloramine paste was applied during the night. If there were 3 or 4 bacteria per field, the experiment was discontinued in order that the wound might be sterilized again. The cicatrization and bacteriological curves of Experiment 4 show that by the application of chloramine paste a wound may be maintained in an appropriately bacteriological condition for carrying out an experiment. Nevertheless, in spite of the antiseptic precautions taken, it was necessary to interrupt this experiment on two occasions, on December 13 to 15 and on December 18 to 22, in order that a complete sterilization of the wound might be effected. When the sterilization was performed as soon as the bacteria were discovered, little retardation occurred in the process of cicatrization. Moreover, the reinfection from the skin was often due to fine bacilli which have but mild retarding action on the rate of healing. The use of at least six flushings in 2 hours with Dakin's solution or of 12 hours' dressing with chloramine paste 10 parts per 1,000, was necessary to keep the wound in a condition of surgical asepsis. The action of distilled water was studied in Experiments 1, 2, and 3. In Experiment 1 the wound was subjected to flushing with distilled water first for 2 hours, then 4 hours, and later for 8 hours per day. The wound was maintained in a condition of mild infection. No marked modification, either acceleration or retardation, was noted in the rate of repair during the period that the treatment was applied. From November 21 to 25 the wound was almost clean and the observed curve remained parallel to the calculated curve, showing that distilled water did not retard the rate of healing. In Experiment 2 the wound was subjected to uninterrupted flushing with distilled water, first for 2 and 8 hours, then for 24 hours. It was continued from November 24 to 30; viz., for 112 hours out of 120, without the occurrence of any marked modification of the course of healing. The bacteriological curve showed that from November 22 to 27 inclusive the wound was kept aseptic. The slight retardation which occurred afterwards was probably brought about by the infection. In Experiment 3 the wound was subjected to flushing with distilled water, first for 2, then for 4, 6, and 8 hours, a total of 20 hours in 4 days. From November 21 to 24 the wound remained surgically aseptic. No modification in the rate of healing occurred. The action of the hypertonic sodium chloride solution was studied in a similar way. In Experiment 4 the wound was flushed at first with 40 per cent sodium chloride solution, from December 4 to 9 for 12 hours a day, and from December 10 to 13 for 24 hours a day, making a total of 144 hours out of 240 hours. At the end of this time the surface area of the wound coincided exactly with the calculated area. Owing to reinfection the experiment was suspended. From December 24 to 29 the wound was kept in contact with 50 per cent sodium chloride solution for 54 hours, and after December 30 flushing with 80 per cent solution for 24 hours a day was resorted to. The total amount of time involved in the above treatments was 174 hours with 40 per cent solution, 72 hours with 50 per cent solution, and 120 hours with 80 per cent solution. On January 1, the surface measured 11 sq. cm. and the calculated surface was 11.3 sq. cm. On January 5 the. surface observed was 10 sq. cm. and the calculated surface was 9 sq. cm. It should be noticed that on January 5 the bacteria numbered 4 per field, which might account for the difference. In Experiment 5 the wound was flushed for 24 hours every day with 50 per cent sodium chloride solution from December 11 to 18, a total of 192 hours. From December 18 to 24 the wound was dressed with agar-agar cakes containing 40 per cent sodium chloride. The concentration was raised to 50 per cent from December 24 to 27. The cicatrization curve indicates only a slight retardation of the repair which can be attributed to infection when both cicatrization and infection curves are compared. The temporary acceleration on the 13th may have been due to the influence of the dressing, but as it did not occur again an experimental error is probably the cause of the change observed in the curve. In Experiment 6 two practically identical wounds at a distance of but a few centimeters from each other were located on the right thigh of Patient 721. The areas of the wounds were respectively 40 and 33 sq. cm. One of the wounds was flushed with distilled water only. The other was subjected to the action of 40 per cent sodium chloride solution. From December 20 to 25 both wounds were in a condition of surgical asepsis. However, the cicatrization curves show that in spite of the difference of treatment the rate of healing was not modified. The rate of healing of the wounds did not therefore apparently undergo any measurable modification under the influence of distilled water or hypertonic salt solution. It is well known that the osmotic changes of the medium have a marked influence on tissues deprived of circulation. But it seems that a tissue with normal circulation is protected by it against the changes of the osmotic pressure occurring at its surface. The above experiments show that apparently the conditions of the tissues of a wound are not modified by the changes of the osmotic pressure of the dressing. The beneficial effects of hypertonic sodium chloride solution on the sterilization of wounds and on the rate of healing recently described by various surgeons are possibly an illusion due to lack of precise technique." }, { "id": "pubmed23n0334_16712", "title": "[Remarks on injuries which were the source of tetanus and were based on observations from the Clinic of Infectious Diseases in Cracow].", "score": 0.009009009009009009, "content": "From 1992 to 1996, 95 patients with tetanus were treated in the Chair and Department of Infectious Diseases in Cracow.

A more accurate characterization of disease was based on the individual reports sent to the Department of Epidemiology, NIPH-NIH. In the last decade the incidence of tetanus has remained below 0.08/100 000 inhabitants. The average annual incidence was lower than in the previous decade, but within the last ten years to the annual variation is difficult to assign a distinct incidence tendency. Rather, they correspond to random fluctuations. In 2010, 16 cases were reported, including which occurred in 2009.

Overall incidence was 0.042/100 000, which was small and not significanty different from incidence in 2009 (0.05/100 000). All cases in 2010, were over 59 years of age, which is a strong expression of the trend observed for years that the disease is present in older age groups where the level of vaccination against tetanus is particularly low.

Three deaths occurred among the 6 cases in people over 79 years of age, mortality 50%. The incubation period of the disease in 3 cases was less than 7 days, in 4 cases 8-14 days, in 4 cases 15-21 days, in 2 cases 22 days and more. Portals of entry of infection in 7 cases accounted for abrasion or laceration, in 6 cases the puncture wound in one it was bitten wound, and in 2 cases, the gates of infection remained unknown. In 3 cases involved people getting vaccinated, and 13 were not given information about the vaccination. No case has not occurred in a person with a documented vaccination. High degree of vaccination of children and adolescents against tetanus makes the tetanus, in these age groups almost completely eliminated, and the few cases occured in people in older age groups. But this is not a disease that can be eliminated from the environment and the risk of non-vaccinated people will always be in the case of injury with rupture of skin and contamination of the wound. Therefore it is important to maintain the current level of children and adolescents vaccinated against tetanus and pay attention to vaccination after injuries and adequate supply of injuries.

The patient had an onset of micrographia at 23 years of the age in 1939. Seven years later he started to drag his right foot, and at 38 years of age, he walked with small steps with festination. Tremor was also present in his right hand. His daily life was independent as a otorhinolaryngologist. He visited our clinic on March 24, 1977 when he was mentally sound and showed mild parkinsonism consisting of masked face, stooped posture, small step gait, bradykinesia, and right side dominant rigidity and tremor. He showed good response to trihexyphenidyl and amantadine HCl. Two month later, he developed dyskinesia and some worsening of parkinsonism, and was admitted to our hospital for the first time. He was treated with 400 to 600 mg/day of levodopa/ carbidopa. He showed marked improvement, however, dyskinesia remained in his mouth. He was doing well until 77 years of age (June of 1993) when he developed hallucination and motor fluctuations. He was admitted again to our hospital on June 22, 1993. On admission, he was alert and appeared mentally sound. However, Hasegawa dementia scale was 18/30. Upward gaze was slightly restricted (3/5). Voice was somewhat small but no masking was noted. His posture was stooped and the gait was of small step. Dyskinesia was noted during walk. No rigidity nor tremor was noted. Deep tendon reflexes were lost but no sensory loss or motor weakness was noted. Routine laboratory studies were unremarkable. A cranial CT scan revealed only mild to moderate cortical atrophy. Motor and sensory conduction velocities were within normal limits, however, motor action potentials could not be obtained with stimulation to the right common peroneal nerve. He was treated with 600 mg/day of levodopa with carbidopa, 100 mg of amantadine HCl, 300 mg of Dops, and 25 mg of tiapride. He continued to show motor fluctuations, and was discharged on July 23, 1993. Since then his motor functions had become progressively worse with frequent falls, but he was still able to walk without support. On October 3 of 1994, he went to bed as usual. On the next morning, he was found dead in his bed at 9: 30. The patient was discussed in neurological CPC, and the chief discussant arrived at the conclusion that the patient had young-onset Parkinson's disease with Lewy bodies in the substantia nigra. Opinions were divided between Parkinson's disease and Lewy body negative young onset parkinsonism. Postmortem examination revealed obstruction of the trachea by aspirated foods, and the cause of death appeared to have been suffocation by the foods. Macroscopically, the external appearance of the brain was unremarkable except for slight frontal atrophy. The substantia nigra showed depigmentation in the lateral part, but the pigmentation of the medial part was well preserved. Upon histologic examination, the number of pigmented neurons in the dorsomedial part was well preserved. In the lateral part, pigmented neurons were well preserved in the dorsal area, however, in the ventral area, only non-pigmented neurons were seen; they appeared to be neurons in the pars reticulata. No gliosis was seen in any of the nigral areas. No Lewy bodies were seen in the remaining neurons. So-called immature neurons with rounded shape without neuromelanin could not be detected. The locus coeruleus neurons were well preserved. The putamen and the other basal ganglia structures were also intact. Slight myelin pallor was noted in the subcortical white matter, however, otherwise cerebral cortices were normal. The histology of this patient is unique in that only the ventrolateral part of the substantia nigra showed abnormal finding consisting of lack of pigmented neurons without gliosis.

PMPB Working Group of the SGGG].", "score": 0.015874015748031496, "content": "2.1. History and clinical-gynecological investigation including a Pap smear are the first step in the clarification. The history should make sure if there is in fact bleeding from the genital and not from the urological or the intestinal region. Drug intake should be recorded, and risk factors for the development of endometrial carcinoma should be considered. This will not affect further investigation. The clinical-gynecological investigation should prove the source of postmenopausal bleeding according to the anatomical site--uterine, infra-, or suprauterine. The causes of infrauterine bleeding may easily be diagnosed by means of inspection of the external genitalia and further by using a speculum. The causes of uterine bleeding are of major importance. Cytology and colposcopy, supported by bimanual investigation, exclude cervical carcinoma as a cause of bleeding. Atypical endometrial cells on the cytological smear arouse suspicion of endometrial carcinoma. 2.2. Transvaginal sonography (TVS) is the next step if the above-mentioned investigations are negative. Both adnexa should always be investigated and the findings sonographically documented, so that solid cystic masses in the adnexal area can be better identified as suprauterine causes of postmenopausal bleeding. Then the uterus should be investigated. Further procedures are decided from the results of measurement of the longitudinal section of the endometrium at the level of maximum endometrial thickness. If the endometrial thickness is _&lt;4 mm, an observant attitude can be assumed. After 3 months the patient should be controlled against using TVS. If bleeding recurs or the endometrial thickness is &gt;4 mm on TVS, the procedure given in subparagraph 2.3 should be followed. In case the endometrial thickness is &gt;4mm or not measurable, a histomorphological investigation according to subparagraph 2.3 should be performed. In such cases, saline infusion sonohysterography(SIS) is useful as a simple method to supplement TVS. It can aid in the decision making as to which further, more invasive measures should be taken (endometrial biopsy/hysteroscopic resection). Computerized tomography or magnetic resonance imaging are, as a rule, not indicated in patients with postmenopausal bleeding. 2.3. A definite diagnosis is possible only on the basis of a histological investigation. If TVS or SS show evidence of a polypoid state, removal under hysteroscopic control is the diagnostic method of choice. In cases of symmetrical or asymmetrical thickening of the endometrium on SIS, a less invasive biopsy may be sufficient. If the biopsy specimen does not yield representative diagnostic material, one should proceed as described above. A fractionated curettage should as a rule not be performed solely, but in combination with hysteroscopy." }, { "id": "pubmed23n0363_9360", "title": "[Transvaginal sonography of the postmenopausal endometrium].", "score": 0.014516430171769977, "content": "The most frequent symptom suggesting endometrial pathology is uterine bleeding. Each postmenopausal uterine bleeding requires fraction explorative curettage and histopathologic examination of the material obtained from the cervical canal and uterine cavity. The aim of this study was to estimate the efficacy of ultrasonography as a non-invasive method in detection of endometrial pathology in postmenopausal women, and to find out whether its more frequent use could safely decrease the number of curettages in detection of these conditions. A prospective investigation has been performed in postmenopausal women not menstruating for more than a year, and who reported to the Department of Obstetrics and Gynaecology in Novi Sad for uterine bleeding during 1996 and 1997. Each woman underwent ultrasonographic examination by vaginal probe of 5 MHz and fraction curettage, whereas the samples from cervical canal (if obtained) and from uterine cavity were sent to histopathologic examination to the Institute of Pathology in Novi Sad. Standard statistical methods have been used for the analysis of the results. Validity of the applied ultrasonographic method in detecting endometrial pathology has been estimated by calculation of its sensitivity and specificity. A satisfactory visualisation of the endometrium has been obtained in all 35 examined cases. The thinnest endometrium was 1 mm wide and the thickest one was--25 mm. The fraction curettage has been used to obtain material from the cervix in 2 cases and from the uterine cavity in 35 cases. In our patients with uterine bleeding, who were in the postmenopause for 13 years on average, endometrial atrophy was recorded in 17.14%, endometrial polyp in 11.43%, endometrial hyperplasia in 22.86%, endometrial adenocarcinoma in 42.86% and uterine sarcoma in 5.71%. There were 2 false negative ultrasonographic findings (2 cases of endometrial hyperplasia) and sonographic thickness less than standard versus 2 false positive cases (endometrium thicker than the limit value, 7 and 14 mm, with no real pathology) which showed that the sensitivity of the investigated method was 93.10% and the specificity was 66.66%, if the limit value for the thickness of endometrium was 3 mm. Ultrasonographic thickness of endometrium means maximum double thickness in longitudinal plane, i.e. the distance of the opposite bordering surfaces of endometrium and myometrium. The procedure of measurements of endometrial thickness is simple in most cases. Most authors agree that there is a positive correlation between the thickness of endometrium and its pathological conditions. The most often used limit values are 3 and 4 mm. Higher limit values of endometrial thickness increase the sensitivity of the method even to 100%, but negatively affect its specificity making this method inadequate as a screening method for endometrial carcinoma. Many authors insist on introducing other criteria for evaluation of the endometrium i.e. for taking its thickness as the only criterion. Ultrasonography does not provide a completely safe differentiation between benign hyperplasia and endometrial carcinoma. The transvaginal sonography is an efficient and acceptable, noninvasive method for early detection of endometrial pathology in postmenopausal women. The thickened endometrium during menopause is the most significant ultrasonographic criterion implicating its pathology. The vaginosonographically measured thickness of 3 mm and less, gives a relatively safe prediction of endometrial atrophy, whereas the thickness above 3 mm requires explorative curettage and histopathologic examination of the endometrium, no matter if the woman has or has not uterine bleeding.

The first biopsy was nearly always taken by selective scraping of the ecto- and endocervix. Technical improvements of this method are explained. The efficiency of cytodiagnosis is especially pointed out by separating cases which could have been recognized or suspected by means of inspection or colposcopy only. 140 out of 282 carcinomata-in-situ and 7 invasive, mainly endocervical cancers (Ib-III), could only be diagnosed by a smear. In 17 woemn who turned out to have invasive cancer (Ib -III) a positive smear was the only reason for admission. Careful inspection of the cervix in the hospital, however, was sufficent to reveal the correct diagnosis. In our material the cervical smear could be of little help in cancer diagnosis of the upper genital tract such as adenocarcinoma of the corpus uteri, sarcoma and ovarian cancer. 39 of the 45 women with endometrial cancer cells in the specimen had bleeding anomalies, especially postmenopausal.

In group CA and H greatest cumulation of abnormal features of TVS image (endometrial thickness &gt; 2.5 mm, hyperechoic, heterogeneous and containing cystic spaces endometrium, deformation of middle echo, indistinctness of endo-myometrial border, presence of focal changes in structure of endometrium and presence of fluid in uterine cavity &gt; 1 cm3) was ascertained (Tab. 2, 3, 4). Hysteroscopic macroscopic image showed conformity with histological estimation in groups BZ, M, P, H and CA properly in 78.35, 93.75, 88.33, 22.22 and 88.33% (Tab. 7). On base of histological estimation 159 (65.7% of chances) of pathological changes (P-68, CA-37, M-32, H-22 chances) were detected (Tab. 8). Among them were 41 of asymptomatic chances (P-24, M-7, H-6, CA-4 chances). In hysteroscopy, all but one chance of pathological changes were detected, however curettage skipped most of focal changes. 1. Ultrasonic measurement of endometrial thickness is sensitive index in detecting cancer and pathological endometrial hyperplasia, instead possesses smaller value in detecting of endometrial polyps and endometrial myomas. 2. Connection of measurement of endometrial thickness with estimation of qualitative features of endometrial and uterine cavity TVS image improves results of detecting all of types intrauterine pathology. 3. Dependence between estrogens level and with thickness of endometrium was confirmed. Practical value of hormonal estimations in diagnostics of endometrial pathological changes is however not large. 4. Analysis of hysteroscopic picture is characterised high agreement with histological investigation with reference to endometrial cancer, endometrial polyps and submucosus myomas. 5. Hysteroskopy with direct biopsy possesses superiority over curettage in detecting all of types of intrauterine pathology, in particular focal changes. 6.

Complete septate uterus with unilateral cervical aplasia (formally Robert's uterus) is characterized by the presence of a uterine septum completely dividing the endometrial cavity into an obstructed hemicavity and a contralateral nonobstructing hemicavity connected normally to the existing cervix. It has always been described as isolated without any associated anomaly. A 30-year-old woman was referred to our department for dysmenorrhea and primary infertility. Hysterosalpingography showed the presence of a right (RT) hemiuterus with a patent fallopian tube; further evaluation with 2- and 3-dimensional ultrasound and magnetic resonance imaging showed an externally normal-appearing uterus, a right normal hemicavity connected normally with the existed cervix and, a left hemicavity fully divided from the right one by a complete septum and not connected with the cervix. Interestingly, a peculiar complex mass with cystic areas, attached posterolaterally from the left side to the uterine wall at the level of the isthmus and the upper cervix, was also diagnosed. The study protocol was approved by our local institutional review board. During outpatient hysteroscopy, a right uterine hemicavity with a single ostium was identified without any communication with the left hemicavity. The patient was then scheduled for combined laparoscopic and hysteroscopic treatment. During laparoscopy, a normal uterine body with multiple myomas and a pseudocystic lesion attached posteriorly and left laterally to the uterus at the level of the isthmus and the upper cervix were shown; no communication between the cystic part of that lesion and the isthmus or the cervicovaginal canal was observed. During hysteroscopy, a longitudinal incision of the septum with a 5F bipolar electrode was performed; the left hemicavity was opened, and the corresponding tubal ostium was identified. The pseudocystic lesion was then excised after opening and sent for pathological analysis; the defect was closed with interrupted intracorporeal knots. A single normal endometrial cavity with both tubal ostia was obtained, thus restoring obstruction by unification of the uterine cavity. A histologic report of the removed pseudocystic lesion was compatible with the diagnosis of mullerian remnants. A follow-up hysteroscopy 3 months after showed a normal uterine cavity without postsurgical adhesions. The use of 3-dimensional ultrasound and magnetic resonance imaging in combination with the new ESHRE/ESGE classification system gives the opportunity to obtain a precise representation of the female genital anatomy even in the presence of complex anomalies. Although a septate uterus with unilateral cervical aplasia has been already described, the presence of mullerian remnants is a rare entity associated with cyclic pelvic pain, thus needing adequate recognition and treatment.

The most common uterine anomaly, septate uterus has a spectrum of configurations ranging from complete septate to incomplete septate uterus. Asymmetric uterine septum was reported only as case reports in the literature and is described as Robert's uterus [2]. This unique malformation is described as a septate uterus with a noncommunicating hemicavity, composed of a blind uterine horn usually with unilateral hematometra, and a contralateral unicornuate uterine cavity. The external uterine shape is normal. The asymmetric septum with transverse uterine septum in the present case has not yet been reported in the literature.

She previously had failed 2 laparoscopy and hysteroscopy procedures for fertility treatments. Hysterosalpingography previously had been failed. The patient previously underwent magnetic resonance imaging. The magnetic resonance imaging report states there was no connection between the uterus and cervix. On external genital organs assessment, there was no abnormal sign. Ultrasonography revealed 2 uterine cavities and hematometra. Both ovaries were in normal view. In view of her examination findings, the patient was scheduled for laparoscopy and hysteroscopy. Laparoscopy revealed extensive adhesions on both the pelvis and upper abdomen. Initially, the uterus and ovaries were not visualized. Adhesiolysis was performed, and normal anatomy was restored. After this step, the operation was continued by laparoscopy and ultrasound-guided hysteroscopy. Under ultrasound and laparoscopy guidance, the transverse uterine septum at the level of uterine isthmus was incised and the left endometrial cavity was observed with hysteroscopy. The asymmetric uterine septum was then incised, and the right-sided endometrial cavity was then accessed. Finally, the uterine septum was completely incised and both sides of the endometrial cavities were merged. The patient had an uncomplicated postoperative course and was discharged 24 hours after surgery. She returned for follow-up examination in the second month after surgery.

Of the pre-menopausal group, 10 underwent curettage following ultrasonographic indications and 42 due to symptoms; the remaining patients underwent hysterectomy due to pathologies not related to the endometrium. A clearly defined role of endovaginal ultrasonography in the diagnosis of endometrial pathologies emerges if ultrasonographic findings are correlated with histological ones. In the group of post-menopausal women (45), all those cases which were histologically classified as endometrial carcinoma (4) were associated with an endometrial thickness over or equal to 4 mm.(ABSTRACT TRUNCATED AT 250 WORDS)" }, { "id": "pubmed23n0314_20681", "title": "Colposcopy, cervicography, speculoscopy and endoscopy.

Diagnostic Cytology Towards the 21st Century: An International Expert Conference and Tutorial.", "score": 0.009174311926605505, "content": "The colposcope was developed in 1925 and is well established in clinical gynecologic practice for defining and delineating cytologically detected lesions mainly of the cervix but also the vagina and vulva. Additionally, various endoscopic procedures in gastroenterology, pulmonary and urologic lesions enhance the cytologic detection and histologic verification of precancerous and cancerous lesions. The cost-effectiveness of all these devices and their applicability, particularly in countries with a limited health budget, is a major issue. This task force considered aspects of the present state of the art and the challenges in the 21st century. Automated cytology can interface with colposcopic examination in a number of significant ways. Automated cytologic analysis of conventional cervical smears can potentially direct colposcopic examination by predicting the nature of a lesion, assist in determining which patients should receive colposcopy and, in some settings, thereby reduce the number of colposcopies. Potentially, various combinations of automated cytology and colposcopy may be used to generate screening protocols that might result in more effective and inexpensive screening. The role of cervicography, or high-resolution cervical photography, as a screening device remains to be defined. Sensitivity for high grade lesions is generally no greater than that in cytology, and specificity appears lower. The interpretation of cervical photographs in triage of mildly abnormal cytology may prove to be useful in countries with established cytology programs. In areas of the world where cytology screening programs are not in place, the interpretation of cervical photographs may have its most dramatic effect. Cost-effectiveness analyses are needed. There are, at present, insufficient data for the evaluation of speculoscopy, a procedure using chemiluminescent illumination of the cervix for visualization of acetowhite areas. Basic training in colposcopy should be integrated into the residency programs of obstetrics and gynecology. Criteria for the adequate training of colposcopists should be developed. Continuing education programs in colposcopy should be developed when they are not already in existence. The cost-effectiveness of integrating colposcopy as a primary screening technique should be evaluated. Following a high-grade squamous intraepithelial lesion (HSIL) cytology result, colposcopically directed punch biopsy should be taken with or without endocervical curettage. This generally should precede the loop electrosurgical excision procedure (LEEP); however, in certain circumstances direct LEEP may be indicated. LEEP under colposcopic vision is an efficient way to treat an HSIL lesion of the cervix because the histologic extent and margins can be determined, unlike with laser surgery or cryosurgery. It is also more cost-effective than cold knife conization because general anesthesia and an operating room are unnecessary. Following LEEP, the endocervical canal should be examined colposcopically for any evidence of involvement. Lesions in the endocervix can then be removed with a different-shaped loop. Further research into Raman spectroscopy as a diagnostic aid in cervical pathology is needed, as is the use of micrococolpohysteroscopy for in vivo cytologic analyses, especially of the endocervical canal and transformation zone. Hysteroscopy is the most direct method for the diagnosis and treatment of intrauterine diseases. Hysteroscopic endometrial biopsy is more accurate than conventional biopsy methods. Cervical invasion of endometrial cancer can be detected by hysteroscopy. The depth of invasion, however, is more accurately determined by magnetic resonance imaging or computed tomography. Many topics for ongoing research and/or implementation are mentioned under \"Consensus Position,\" above.

Adenocarcinoma is a rare type of cervical cancer: III cases out of 584 patients with cervical cancer in 2003 in the Netherlands. This neoplasm is more difficult to detect than cervical squamous cell carcinoma. Cervical cytology is not an effective tool for screening and diagnosis. Due to the localization, multifocality and diversity in its presentation, the assessment of cytology has a high false-negative percentage. Screening may be enhanced by combining cytology with testing for high-risk HPV types, notably type 18.

In the second stage, the patients underwent hysteroscopy/endometrial bipyroscopy with morphological evaluation of tissue samples, which retrospectively performed analysis of echographic and dopplerometric criteria in patients with benign changes in the endometrium and their comparison with atrophic endometrium. In addition, a comparative analysis of the 2D ultrasound method and its combination with a complex 3D study was carried out. Most of the echographic criteria between the groups of hyperproliferative pathology and endometrial atrophy had statistical differences, but there were no significant differences in comparison with the group of synechia of the uterine cavity and cystic atrophy. While the analysis of Dopplerometric criteria both in the two-dimensional mode and with its combination with trimer techniques demonstrated a statistical difference between the indices in the groups of the endometrial hyperpliphyral pathology and the endometrium atrophy, including its cystic form, and also the synechia of the uterine cavity. Based on the results of the comparative analysis of the ultrasound modes, the combination of 2D study with a complex 3D study increases the sensitivity of the method by 12%, and the specificity by 13%. Three-dimensional echography with the determination of dopplerometric indices and volume of endometrium and 3D reconstruction is highly accurate in the diagnosis of endometrial pathology, its wide practical application at the preoperative stage will allow to improve the quality of diagnostics and to formulate clear criteria for hysteroscopy in postmenopausal women.

Hyperaccumulation of lipophilic tracer on SPECT study, especially in the temporal lobes, has been reported in the early stage of HSVE by previous investigators.

We report here a case where a late diagnosis of a disease owing to inconclusive results leads to dissemination. The complications following the introduction of the treatment based on presumption lead to further difficulty. We remained inclined to our diagnosis based on clinical judgement, acknowledged and managed the inflammatory changes secondary to the infection, and finally won the long battle. So, sometimes we need to make decisions based on clinical grounds. We need to depend on the fact that uncommon presentations of common diseases are commoner than a common presentation of uncommon diseases." }, { "id": "pubmed23n1130_10328", "title": "[COVID-19 and herpesvirus encephalitis].", "score": 0.009615384615384616, "content": "The SARS-CoV-2 virus, which causes COVID-19, could give rise to damage the nervous system.

Specific chief complaints have to be recognized in order to narrow down the differential diagnosis. In cases of life-threatening illnesses, such as septicemia, endocarditis, bacterial meningitis and severe pneumonia, the first diagnostic and therapeutic steps should be performed in a rapid sequence: bacterial blood samples, sputum and/or liquor samples are required and the initial antibiotic therapy has to be chosen empirically as the relevant bacterial spectrum related to the suspected illness must be covered. In less urgent cases it is recommended that a multi-step diagnostic approach be carried out which takes the differential diagnosis into account and prioritizes the probabilities. In the latter situation antibiotic treatment should be delayed to diagnose the infection correctly. Importantly, atypical courses must necessitate careful and critical reassessment of the diagnosis.

Many other pathogens can occasionally cause bacterial meningitis, often under special clinical circumstances. Treatment of meningitis includes two main goals: Eradication of the infecting organism, and management of CNS and systemic complications. Empiric therapy should be initiated without delay, as the prognosis of the disease depends on the time when therapy is started. One or two blood cultures should be obtained before administering the first antibiotic. Empiric therapy is primarily based on the age of the patient, with modifications if there are positive findings on CSF gram stain or if the patient presents with special risk factors. It is safer to choose regimens with broad coverage, as they can usually be modified within 24-48 hours, when antibiotic sensitivities of the infecting organism become available. Adjunctive therapy with dexamethasone is also administered in severely ill patients concomitantly with the first antibiotic dose. In patients who are clinically stable and are unlikely to be adversely affected if antibiotics are not administered immediately, including those with suspected viral or chronic meningitis, a lumbar puncture represents the first step, unless there is clinical suspicion of an intracerebral mass lesion.

Initial noncontrast computed tomography of the brain revealed a hyperdensity in the hypothalamic region surrounded by hypodensities extending toward the bilateral temporal lobes; these findings were consistent with a possible hypothalamic tumor with perilesional edema. The patient later developed cranial diabetes insipidus, which was further suggestive of hypothalamic disease. Interestingly, gadolinium-enhanced magnetic resonance imaging of the brain showed no such lesions; instead, it showed prominent T2-weighted signals in the inner mesial region, characteristic of encephalitis.

It is interesting to note that the diagnosis of the primary neurologic disease of this patient was not easy even after autopsy. As autopsy permission was obtained only for the brain, it was not clear whether or not this patient had an occult malignancy somewhere in her body, however, there was no evidence to indicate paraneoplastic degeneration of the central nervous system.

Reading the answers, the first thing that is clear to us is that acenocoumarol should NOT be given to a pregnant woman because of the risk of teratogenicity. Anyone who does so during residency should be punished with 100 slaps on the back. We discard answer 5. Second: if treatment is given, it should be during the entire pregnancy, prothrombotic status is not only during the puerperium, so answer 2 discarded. Advise a woman not to become pregnant when there are treatments that ensure a very low risk of thrombosis and/or fetal involvement? Answer 1 discarded. We are left with the possibility of not giving any treatment because it is low risk or administering low-dose aspirin. It is true that factor V Leiden in heterozygosis is classified as low risk, who has not presented a previous thrombotic episode nor is there a combination with another thrombophilia; if we look at the CHEST guide, VIII edition and review what was said at the last congress of the Spanish Society of Gynecology and Obstetrics, we see that aspirin is used in case of phospholipid syndrome and that in the case of this woman, without previous thrombosis, without previous abortions (at least two are needed) and also being heterozygous, treatment is not necessary.

Postpartum prophylaxis should be given to all women with an increased risk for VTE. A large body of evidence has been presented that hypercoagulability may cause recurrent abortions, stillbirth, and preeclampsia. There is no doubt that the antiphospholipid syndrome is strongly associated with fetal loss.

The data presented in the paper have been extracted from the Current Contents database. It is well known that the hypercoagulable state in pregnant women, caused either by the physiological changes of pregnancy or by inherited thrombophilia, increases the risk of venous thromboembolism (VTE), pulmonary embolism (PE), preeclampsia, recurrent early and late fetal loss, intrauterine growth retardation (IUGR), placental abruption, and other less probable complications of pregnancy and its outcome. In women with mechanical heart valves, the risk of systemic embolism is also seen to increase during pregnancy. According to data analyzed, positive antiphospholipid antibodies (APLA) as well as anticardiolipin antibody and lupus anticoagulant (nonspecific inhibitor) positivity, homozygosity and heterozygosity for factor V Leiden mutation and heterozygosity for the prothrombin G20210A variant, MTHFR C677T variant homozygosity and hyperhomocysteinemia are in strong association with pregnancy complications and severe pregnancy outcome. The strongest association for late fetal loss was seen in women with protein S deficiency. In order to reduce such risks, anticoagulation therapy is administered throughout pregnancy. The antithrombotic agents available for the prevention and treatment of VTE during pregnancy and pregnancy complications include unfractionated heparin (UFH), low-molecular-weight heparin (LMWH) and aspirin. Vitamin K antagonists are contraindicated in pregnancy. Low-dose aspirin may have a role in the prevention of some pregnancy complications, although its safety in early pregnancy is uncertain. LMWH and UFH are quite safe and efficacious when properly selected, dosed and monitored. The efficacy and safety of LMWH have been demonstrated in the prevention and treatment of VTE in pregnancy. LMWH in association with aspirin administered throughout pregnancy have been shown to be associated with a lower risk of complications in women with APLA syndrome. Women at a high risk of preeclampsia are recommended to use low-dose aspirin throughout pregnancy. When there is a history of preeclampsia, the administration of anticoagulation therapy is not recommended as a prophylaxis in subsequent pregnancies, as the risk appears to be already decreased as compared with previous pregnancy. LMWH has probable advantages over UFH for the incidence of side effects. In pregnant women with mechanical heart valves, anticoagulant therapy during pregnancy should include assessment of additional risk factors for thromboembolism including valve type, position, and history of thromboembolism, and decision should also be strongly influenced by the patient's preferences. If the risk of thromboembolism in patients with mechanical heart valves is considered very high, and efficacy or safety of prophylaxis with UFH or LMWH is not satisfactory (older-generation prosthesis in the mitral position or history of thromboembolism), administration of vitamin K antagonists throughout pregnancy is recommended with replacement by UFH or LMWH close to delivery. It should be considered that limited effectiveness of UFH or LMWH in patients with mechanical heart valves might be due to inadequate dosing. The necessity of anticoagulation therapy in women with inherited or acquired thrombophilia is biologically plausible; nevertheless, optimum management in such cases remains unknown." }, { "id": "pubmed23n0448_2051", "title": "Thrombosis during pregnancy: risk factors, diagnosis and treatment.", "score": 0.01589323627540188, "content": "Venous thromboembolism occurs infrequently but is a leading cause of illness and death during pregnancy and the puerperium and remains a diagnostic and therapeutic challenge.

Grade 2 recommendations are weaker and imply that the magnitude of the benefits and risks, burden, and costs are less certain. Support for recommendations may come from high-quality, moderate-quality or low-quality studies; labeled, respectively, A, B, and C. Among the key recommendations in this chapter are the following: for pregnant women, in general, we recommend that vitamin K antagonists should be substituted with unfractionated heparin (UFH) or low-molecular-weight heparin (LMWH) [Grade 1A], except perhaps in women with mechanical heart valves. For pregnant patients, we suggest LMWH over UFH for the prevention and treatment of VTE (Grade 2C). For pregnant women with acute VTE, we recommend that subcutaneous LMWH or UFH should be continued throughout pregnancy (Grade 1B) and suggest that anticoagulants should be continued for at least 6 weeks postpartum (for a total minimum duration of therapy of 6 months) [Grade 2C]. For pregnant patients with a single prior episode of VTE associated with a transient risk factor that is no longer present and no thrombophilia, we recommend clinical surveillance antepartum and anticoagulant prophylaxis postpartum (Grade 1C). For other pregnant women with a history of a single prior episode of VTE who are not receiving long-term anticoagulant therapy, we recommend one of the following, rather than routine care or full-dose anticoagulation: antepartum prophylactic LMWH/UFH or intermediate-dose LMWH/UFH or clinical surveillance throughout pregnancy plus postpartum anticoagulants (Grade 1C). For such patients with a higher risk thrombophilia, in addition to postpartum prophylaxis, we suggest antepartum prophylactic or intermediate-dose LMWH or prophylactic or intermediate-dose UFH, rather than clinical surveillance (Grade 2C). We suggest that pregnant women with multiple episodes of VTE who are not receiving long-term anticoagulants receive antepartum prophylactic, intermediate-dose, or adjusted-dose LMWH or intermediate or adjusted-dose UFH, followed by postpartum anticoagulants (Grade 2C). For those pregnant women with prior VTE who are receiving long-term anticoagulants, we recommend LMWH or UFH throughout pregnancy (either adjusted-dose LMWH or UFH, 75% of adjusted-dose LMWH, or intermediate-dose LMWH) followed by resumption of long-term anticoagulants postpartum (Grade 1C). We suggest both antepartum and postpartum prophylaxis for pregnant women with no prior history of VTE but antithrombin deficiency (Grade 2C). For all other pregnant women with thrombophilia but no prior VTE, we suggest antepartum clinical surveillance or prophylactic LMWH or UFH, plus postpartum anticoagulants, rather than routine care (Grade 2C). For women with recurrent early pregnancy loss or unexplained late pregnancy loss, we recommend screening for antiphospholipid antibodies (APLAs) [Grade 1A]. For women with these pregnancy complications who test positive for APLAs and have no history of venous or arterial thrombosis, we recommend antepartum administration of prophylactic or intermediate-dose UFH or prophylactic LMWH combined with aspirin (Grade 1B). We recommend that the decision about anticoagulant management during pregnancy for pregnant women with mechanical heart valves include an assessment of additional risk factors for thromboembolism including valve type, position, and history of thromboembolism (Grade 1C). While patient values and preferences are important for all decisions regarding antithrombotic therapy in pregnancy, this is particularly so for women with mechanical heart valves. For these women, we recommend either adjusted-dose bid LMWH throughout pregnancy (Grade 1C), adjusted-dose UFH throughout pregnancy (Grade 1C), or one of these two regimens until the thirteenth week with warfarin substitution until close to delivery before restarting LMWH or UFH) [Grade 1C]. However, if a pregnant woman with a mechanical heart valve is judged to be at very high risk of thromboembolism and there are concerns about the efficacy and safety of LMWH or UFH as dosed above, we suggest vitamin K antagonists throughout pregnancy with replacement by UFH or LMWH close to delivery, after a thorough discussion of the potential risks and benefits of this approach (Grade 2C)." }, { "id": "pubmed23n0357_22237", "title": "[Current management of thromboembolism in pregnancy and puerperium].", "score": 0.01497939636930616, "content": "Venous thromboembolism (VTE) remains the leading cause of maternal death.

For deep vein thrombosis (DVT) the diagnostic tool of choice is color-coded duplex-sonography, for pulmonary embolism (PE) perfusion/ventilation lung scan can be used. Integrating a detailed individual and family history, the presence of thrombophilia or other risk factors, a risk stratification can be undertaken. These risk categories are defined in the present paper and the appropriate treatment measures are described.

Thus, in pregnant carriers of either one of these mutations the risk of venous thromboembolism is low. Therefore, no heparin prophylaxis is recommended.

The knowledge about the clinical relevance of thrombophilic defects is increasing, and evidence-based indications for thrombophilia screening are therefore discussed in this review. Selective thrombophilia screening based on previous personal and/or family history of venous thromboembolism is more cost-effective than universal screening in all patient groups evaluated. In the majority of patients with acute venous thrombosis, the results of thrombophilia screening do not influence the duration of oral anticoagulation. The only patient population who clearly profits from thrombophilia screening in this situation are patients with a newly diagnosed antiphospholipid syndrome, because prolonged anticoagulation can avoid the high incidence of recurrence in this patient population. Because of the increased risk of venous thrombosis during pregnancy and the puerperium, thrombophilia screening is indicated in selected patients with a previous history of venous thrombosis or a positive family history. Significant associations with early and late pregnancy loss are observed for carriers of the heterozygous factor V Leiden mutation, the heterozygous prothrombin-mutation G20210A and anticardiolipin antibodies, while protein S deficiency is significantly associated with late pregnancy loss. Antithrombotic drugs like UFH, LMWH or low-dose aspirin may have a potential therapeutic benefit in patients with recurrent pregnancy loss and thrombophilia, but placebo-controlled, multicenter trials are urgently needed to clarify this issue. Although a supra-additive effect for the risk of venous thrombosis is observed between oral contraceptives and some thrombophilias, the absolute incidence of venous thromboembolism is low in premenopausal women and mass screening strategies are therefore unlikely to be effective.

Thrombophilia, smoking, obesity, immobility and postpartum factors such as infection, bleeding and emergency surgery (including emergency caesarian section) also increase the risk of pregnancy-related VTE. The diagnosis of VTE can be safely established with acceptable radiation exposure to the fetus using readily available imaging modalities such as ultrasound, ventilation perfusion lung scanning and computed tomographic pulmonary angiography.

If there is no contraindication to anticoagulation, commencing treatment prior to objective confirmation should be strongly considered. For the mother and fetus, effective and safe treatment is readily available with low-molecular-weight heparin (LMWH), but optimal dosing of these agents in pregnancy remains controversial. Emerging data support antepartum LMWH prophylaxis for women with previous VTE if the event was unprovoked or in the presence of thrombophilia.

We present a case of lumbar stenosis manifesting as a multilevel radiculopathy inferior to the nerve roots at the level of the stenosis. A 55-year-old gentleman presented with bilateral lower extremity pain with neurogenic claudication in an L5/S1 distribution (posterior thigh, calf, into the foot) concomitant with dorsiflexion and plantarflexion weakness. Imaging revealed grade I spondylolisthesis of L3 on L4 with severe spinal canal stenosis at L3-L4, mild left L4-L5 disc herniation, no stenosis at L5-S1, and no instability. EMG revealed active and chronic L5 and S1 radiculopathy. The patient underwent bilateral L3-L4 hemilaminotomy with left L4-L5 microdiscectomy for treatment of his L3-L4 stenosis. Postoperatively, he exhibited significant improvement in dorsiflexion and plantarflexion. The L5-S1 level was not involved in the operative decompression. Patients with radiculopathy and normal imaging at the level corresponding to the radiculopathy should not be ruled out for operative intervention should they have imaging evidence of lumbar stenosis superior to the expected affected level.

The physical examination showed that tenderness and percussion pain were present at L4-S1 spinous process. Straight leg raise test: 50° on the left side were positive. Laboratory tests showed that the sUA was 669 μmol/L, MRI of the lumbar spine showed that cystic T1WI low signal and T2WI mixed high signal shadows were seen in the spinal canal at the level of L4-L5. Combining with lab examinations, imaging examinations, and histopathological results, the patient was diagnosed with lumbar spinal canal tophi. After active improvement of all examinations, the patient underwent surgical treatment with decompression and internal fixation of the L4-L5 segment. After surgery, the patient's symptoms improved and muscle strength returned to normal. Among the 95 previously reported patients with lumbar gout, the ratio of men to women was 2.96:1, and the peak age group of incidence was 56 to 65 years. The onset of the disease was mainly in a single segment of the lumbar spine, with 34.41% of all cases occurring at the L4-L5 level. 61.05% of the patients had a history of gout attacks or hyperuricemia, and the most frequently involved site was the foot and ankle, followed by the wrist. Sixty-seven patients underwent surgical treatment, and 22 chose conservative treatment, with overall satisfactory results. The incidence of lumbar gout is low and relatively rare in the clinic and pathological biopsy is still the gold standard. Vertebral plate incision and decompression are often selected for surgical treatment, and whether to perform fusion should be comprehensively considered for the destruction of vertebral bone by gout and the reasonable selection of the extent of surgical resection. Whether choosing surgical treatment or conservative therapy, the control of uric acid levels should be emphasized." }, { "id": "pubmed23n0977_4210", "title": "Limbus Vertebral Fracture Presenting as Cauda Equina Syndrome Masquerading An Acute Disc Prolapse - A Rare Case Report and Review of Literature.", "score": 0.013368549370174725, "content": "Limbus vertebral fracture is an uncommon injury described in adolescents.

This was associated with urinary retention and numbness in perineal region. Examination revealed L5 and S1 weakness with absent ankle jerks bilaterally. Bulbocavernosus reflex was absent. Emergency magnetic resonance imaging imaging was done, which revealed a limbus fracture of cephalad part of L4 vertebral body with displaced fragment into the spinal canal causing compression of the cauda equina.

No complications during and after the operation were observed. Further, the radiating pain and back pain improved, and the patient was discharged. Two weeks after the operation, the patient visited the outpatient department complaining of sudden recurred pain, which occurred while going to the bathroom. Radiography and computed tomography revealed a split fracture of the L5 body and an anterior cage displacement. In revision of OLIF, we removed the dislocated cage and filled the bone cement between the anterior longitudinal ligament and empty disc space. Further, we performed posterior lumbar interbody fusion L4-5, and the screw was extended to S1. After the second surgery, back pain and radiating pain in the left leg improved, and he was discharged without complications. In this case, owing to insufficient intervertebral space during L4-5 OLIF, a huge cage was used to achieve sufficient segmental lordosis after anterior column release, but a vertebral body coronal fracture occurred. In patients with poor bone quality and less flexibility, a huge cage and over-distraction could cause a vertebral fracture; hence, selecting an appropriate cage or considering a posterior approach is recommended." }, { "id": "InternalMed_Harrison_1467", "title": "InternalMed_Harrison", "score": 0.009363657839915811, "content": "Nerve root injury (radiculopathy) is a common cause of neck, arm, low back, buttock, and leg pain (see Figs. 31-2 and 31-3).

Pituitary apoplexy is a syndrome characterized by the sudden onset of headache accompanied by ocular motility disturbances and a variable degree of pituitary insufficiency. The cause is usually a rapidly growing pituitary mass secondary to a vascular event (infarction or hemorrhage). General symptoms may range from vomiting or nausea to meningeal irritation. Compression on the chiasm and optic nerve can cause various campimetric deficits (usually greater bitemporal hemianopsia in the superior quadrants) and decreased visual acuity, even blindness. If the mass grows lateral to the sella turcica it can compress the oculomotor nerves, with the common motor ocular nerve being the most frequently affected, because of its more medial course in the cavernous sinus. The test of choice for the diagnosis of pituitary apoplexy is MRI, as CT may not distinguish the region clearly enough to distinguish degenerative or cystic changes from previous bleedings. The finding of erosion of the anterior clinoid processes in the skull CT may support a chronic lesion, which as a result of an acute vascular phenomenon has caused the symptoms. The management of these patients involves strict control of water and electrolyte disturbances and correction of hormonal deficits. In unstable situations as in the case described, with significant visual disturbances, surgical intervention is usually of choice, with transsphenoidal decompression.

We report a 45-year-old man who presented to our emergency department with a sudden onset headache, acute confusion, signs of meningeal irritation and ophthalmoplegia. An initial diagnosis of acute meningoencephalitis was made, which was amended to pituitary apoplexy following thorough investigation within the emergency department.A 45-year-old man was brought to our emergency department by ambulance with a history of sudden onset of frontal headache and acute confusion. His wife provided the history. There was no significant past medical history of diabetes, hypertension, recent travel abroad, exposure to sick contacts, involvement in outdoor pursuits such as hiking/cave diving, or trauma. He worked in a bank and had been well until 24 h prior to the onset of sudden headache, which was gradually worsening in nature and associated with increasing confusion. The patient's wife reported that he had neither experienced any fevers, night sweats, or coryzal symptoms nor received any recent vaccinations. He was not on any regular medications. He was a non-smoker and occasionally consumed alcohol. There was no significant family history. On examination in the ED, his temperature was 37.6°C, his pulse was 110/min, and he was normotensive and normoglycaemic. A macular blanching rash was noted over the patient's trunk. The patient was disoriented to time and place. Neurological examination revealed reduced GCS (11/15-E3, M6, V2), marked neck stiffness, a positive Kernig's sign and a right sixth nerve palsy.A provisional diagnosis of acute meningoencephalitis was made and the patient was started on a course of intravenous antibiotics with benzyl penicillin 1.2 g, cefotaxime 2 g and acyclovir 750 mg. Baseline blood investigations revealed hyponatraemia (122 mmol/l), a white-cell count of 11 × 109/l and a C-reactive protein &gt; 250. Due to the sudden onset of the symptoms and lack of prodrome, an urgent CT head scan was performed to rule out a cerebrovascular event. The scan demonstrated an enlarged pituitary gland (3 cm in diameter) with impingement of the optic chiasm. The centre of the enlarged pituitary gland was noted to be hypodense in comparison to its periphery, which was consistent with a diagnosis of pituitary apoplexy. A subsequent MRI confirmed the diagnosis (Figure 1) of an enlarged sella containing abnormal soft tissue with increased signal intensity suggestive of haemorrhage (Figure 1A).Post-MRI a lumbar puncture was performed revealing glucose 3.4 mmol/l, protein 1.0 g/l, red cells of 53/mm3 and white cells of 174/mm3 with predominant neutrophilia. No organisms were seen, and CSF cultures and HSV DNA tests were found to be negative. Endocrinological investigations demonstrated low concentrations of thyroid hormones [TSH: 0.14 mIu/l (0.35-5.5 mlU/l), FT3: 1.1 nmol/l (1.2-3.0 nmol/l), FT4: 9.6 pmol/l (8-22 pmol/l)], gonadal hormones (LH: &lt; 1 u/l) and prolactin: 16 u/l (&lt;450 u/l). Serum FSH was 2.9 u/l (0.8-11.5 u/L) and cortisol 575 nmol/l (450-700 nmol/l). The patient was treated for hypopituitarism based on clinical and radiological findings with intravenous fluids, hydrocortisone (100 mg) and thyroxine (50 μg) as loading doses in the ED.Within 24 h of commencement of therapy the patient's GCS rose to 15, and within 48 h there was marked improvement in the right sixth cranial nerve palsy. Formal visual field assessment demonstrated temporal visual field loss in the left eye. The patient was discharged to his usual residence a week later and follow-up was organised with both the endocrinologists and ophthalmologists.

CT scans on admission did not clearly reveal the Sylvian fissures and the mesencephalic cistern, without any mass effects. A lumbar puncture demonstrated xanthochromic cerebrospinal fluid (CSF), which was considered to be responsible for her headache. Cerebral angiography performed on day 4 failed to demonstrate any cerebral vascular disorders. Follow-up CT scans on day 7 demonstrated a high density lesion in the left subdural space. Magnetic resonance images (MRIs) confirmed a diagnosis of bilateral chronic subdural hematomas. Removal of the hematomas cleared all signs and symptoms smoothly. The second case was a 44-year-old man who was referred from another hospital because of xanthochromic CSF found by lumbar puncture. He began to suffer headache and be subject to vomiting 6 weeks earlier and these symptoms were still present on the day of admission. CT scans did not clearly show the cerebral cisterns without mass effects. Because the second lumbar puncture showed xanthochromic CSF again, SAH from aneurysm was suspected. However, emergency cerebral angiography failed to demonstrate cerebral aneurysms. MRI performed two days later demonstrated bilateral chronic subdural hematomas.

In both cases, a retrospective study of the angiograms revealed the evidence of bilateral avascular areas over the convexities in the venous phase.

All patients were comatose following head injury (GCS less than or equal to 8) and were treated homogeneously by the same neurosurgical team by a protocol that included immediate resuscitation on arrival, diagnosis of intracranial lesions by angiography, early surgery when needed, mechanical ventilation, steroids, and mannitol. Extracranial lesions, even if preponderant, were treated by various specialists in the Neurosurgical Department, which for all practical purposes operated as an Emergency Department.

A little less than half the patients made good recoveries or remained moderately disabled (47%); 6% were severely disabled, and 2% survived in a persistent vegetative state. More than two-thirds of the patients were brought to our Neurosurgical Department after a short stay at a general hospital; 72% were admitted within 6 hours of injury; 71% were traffic accident victims; and 34% had significant associated extracranial injuries. Carotid angiography was performed in 78% of the patients and indicated the presence of an intracranial haematoma requiring surgery in 36% of the whole series. Mortality was significantly higher in operated than in unoperated patients (56% versus 39%); those treated surgically, however, were older, in worse clinical condition, and showed a higher incidence of acute subdural haematomas associated with brain contusion. Carotid angiography proved very effective in revealing the presence of an expansive lesion but failed to reflect the severity of brain damage, since the group with \"negative\" angiograms showed a high mortality (52%).

Cranial imaging (mainly MRI) is useful in the course of bacterial meningitis. Patients who do not respond well to treatment or with atypical presentation, persistence of fever, or new neurological signs should undergo brain imaging; MRI and CT may identify subdural effusions, brain abscesses, empyemas, hydrocephaly, or brain parenchymal changes (cerebritis, infarction, hemorrhage). CT and MRI are useful to screen for an ENT cause of bacterial meningitis, and mandatory in case of pneumococcal meningitis.

Four years after the surgery (December of 1994 at her 64 years of the age), she noted suboccipital headache and nausea which had become progressively worse and she was admitted to our service on May 24, 1995. On admission, she appeared chronically ill but general physical examination was unremarkable with normal vital signs. Neurologically she was alert and not demented, and the higher cerebral functions were intact. Cranial nerves were also unremarkable. She was able to walk in tandem and on heels. No motor weakness or ataxia was noted. Deep tendon reflexes were moderately increased, however, no Babinski sign was noted. Although she had headache, no meningeal signs were seen. Slight superficial and vibratory sensory loss was noted in both feet. Routine blood work was again unremarkable except for slight increase in CEA to 8.3 ng/dl (N &lt; 5 ng/dl). The opening pressure of lumbar CSF was 180 mm H2O and the CSF contained 39 cells/microliter, 79 mg of protein, and 10 mg/dl of glucose. Approximately half of the cells were atypical malignant cells. Plain CT was unremarkable, however, tentorial border showed enhancement after contrast infusion. FGS showed no malignant tumors in the stomach. She was treated with intravenous glycerol and whole brain radiation, however, she continued to complain of severe headache, and her sensorium started to be disturbed one month after the admission. Follow-up cranial CT scan revealed enlargement of the lateral and the third ventricles. Her consciousness progressively deteriorated and she became comatose three months after the admission. Repeated cranial CT scan showed enlargement of the ventricles, but no mass lesions were seen within the brain. She developed respiratory arrest on September 25 of the same year. She was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had a gastric cancer with meningeal seeding developing meningeal carcinomatosis. The cause of deep coma was ascribed to damage of cerebral cortical areas secondary to metastatic carcinoma cells and fibrinous materials in the surface of the brain. Postmortem examination revealed thickening and clouding of leptomeninges of the cerebral convexity. On histologic observation, patchy areas of fibrous thickening were seen in the cerebral leptomeninges; in such areas, adenocarcinomatous cells were seen scattered. The basal meninges were free of carcinoma cells, however, leptomeninges of the cerebellum and brain stem tegmentum contained scattered carcinoma cells. The lateral and the third ventricles were enlarged, however, insides of the brain were free of pathologies; the ependymal layer were intact. In the stomach no carcinoma cells were remaining. Pneumonic changes were seen in the right upper and the left lower lobes which appeared to be the direct cause of her death. No evidence of tentorial herniation was noted.

According to the SEGO (Spanish Society of Gynecology and Obstetrics) in its 2005 protocol "Gestational trophoblastic disease", the risk of malignization, i.e. of developing a gestational trophoblastic neoplasm, ranges from 5 to 20% depending on whether it is a partial mole or a complete mole, respectively. According to this protocol: "Patients will be monitored weekly with hcg dosage until it becomes undetectable, for three consecutive times. After that the monitoring will be monthly, for six months and then every two months for another six months. Based on the available data, a follow-up of three to six months is recommended for partial mole and 12 months for complete mole." Therefore, subsequent controls are strictly necessary.The risk of a new molar gestation, although increased compared to the normal population, is not 50%.

WHO modified its risk factor scoring system. This change was proposed to combine both the basic FIGO anatomic staging with the modified WHO risk factor scoring system. Patients who score as low-risk are treated with single agent chemotherapy, such as methotrexate (MTX), and patients refractory to MTX are treated with a combination chemotherapy, EMA/CO. Patients who score as high-risk are treated with EMA/CO, and patients refractory to the first line chemotherapy may be successfully treated with EP/EMA. Recent epidemiological data showed that women with complete hydatidiform moles could anticipate normal reproduction in the future. Studies found that pregnancies after treatment of molar pregnancy resulted in 69% full-term, live births; 8% premature deliveries; 1% ectopic pregnancies, and 0.5% stillbirths. First-trimester spontaneous abortions occurred in 17% of pregnancies, and major and minor malformations were detected in 0.4% of infants. Patients with hydatidiform mole were at increased risk of developing molar pregnancy in subsequent conceptions. After having one molar pregnancy, the risk of having molar disease in a future gestation was about 1%. The risk of persistent gestational trophoblastic tumors was increased by long-term oral contraceptive use before conception. In a large, multicenter, case-control study, the risk was shown to be increased in women who had ever used oral contraceptives, but was highest for women taking oral contraceptives during the cycle in which they became pregnant. Partial hydatidiform moles were never previously proven to transform into choriocarcinoma; however, a recent study with molecular techniques clearly showed that partial moles could transform into choriocarcinoma.

We suggest that the risk of pGTD developing from a histologically confirmed non-molar HA is less than 1 in 50,000 and that the majority of pGTD cases previously reported to have been caused by a non-molar miscarriage probably represent disease due to an unrecognised early molar pregnancy." }, { "id": "wiki20220301en036_29140", "title": "Gestational trophoblastic disease", "score": 0.01404869640163758, "content": "In this scoring system, women with a score of 7 or greater are considered at high risk.

For meta-analysis, cumulative incidence of gestational trophoblastic neoplasia, with CIs by the Agresti-Coull method, and pooled risk ratios (RRs) comparing complete and partial mole were calculated. Among the 19 eligible studies that reported adequate data for inclusion in the primary meta-analysis, we found low incidence of gestational trophoblastic neoplasia after normal hCG level following both complete mole (64/18,357, 0.35%, 95% CI 0.27-0.45%), and partial mole (5/14,864, 0.03%, 95% CI 0.01-0.08%). There was a significantly higher risk of gestational trophoblastic neoplasia after complete compared with partial molar pregnancy (RR 4.72, 95% CI 1.81-12.3, P=.002).

However, there are little data underlying such recommendations, and recent evidence has demonstrated that gestational trophoblastic neoplasia diagnosis after human chorionic gonadotropin normalization is rare. We sought to estimate the cost-effectiveness of alternative strategies for surveillance for gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after complete and partial molar pregnancy. A Markov-based cost-effectiveness model, using monthly cycles and terminating after 36 months/cycles, was constructed to compare alternative strategies for asymptomatic human chorionic gonadotropin surveillance after the first normal (none; monthly testing for 1, 3, 6, and 12 months; or every 3-month testing for 3, 6, and 12 months) for both complete and partial molar pregnancy. The risk of reduced surveillance was modeled by increasing the probability of high-risk disease at diagnosis. Probabilities, costs, and utilities were estimated from peer-reviewed literature, with all cost data applicable to the United States and adjusted to 2020 US dollars. The primary outcome was cost per quality-adjusted life year ($/quality-adjusted life year) with a $100,000/quality-adjusted life year willingness-to-pay threshold. Under base-case assumptions, we found no further surveillance after the first normal human chorionic gonadotropin to be the dominant strategy from both the healthcare system and societal perspectives, for both complete and partial molar pregnancy. After complete mole, this strategy had the lowest average cost (healthcare system, $144 vs maximum $283; societal, $152 vs maximum $443) and highest effectiveness (2.711 vs minimum 2.682 quality-adjusted life years). This strategy led to a slightly higher rate of death from gestational trophoblastic neoplasia (0.013% vs minimum 0.009%), although with high costs per gestational trophoblastic neoplasia death avoided (range, $214,000 to &gt;$4 million). Societal perspective costs of lost wages had a greater impact on frequent surveillance costs than rare gestational trophoblastic neoplasia treatment costs, and no further surveillance was more favorable from this perspective in otherwise identical analyses. No further surveillance remained dominant or preferred with incremental cost-effectiveness ratio of &lt;$100,000 in all analyses for partial mole, and most sensitivity analyses for complete mole. Under the assumption of no disutility from surveillance, surveillance strategies were more effective (by quality-adjusted life year) than no further surveillance, and a single human chorionic gonadotropin test at 3 months was found to be cost-effective after complete mole with incremental cost-effectiveness ratio of $53,261 from the healthcare perspective, but not from the societal perspective (incremental cost-effectiveness ratio, $288,783). Largely owing to the rare incidence of gestational trophoblastic neoplasia after human chorionic gonadotropin normalization after molar pregnancy, prolonged surveillance is not cost-effective under most assumptions. It would be reasonable to reduce, and potentially eliminate, current recommendations for surveillance after human chorionic gonadotropin normalization after molar pregnancy, particularly among partial moles. With any reduction in surveillance, patients should be counseled on symptoms of gestational trophoblastic neoplasia and established in routine gynecologic care." }, { "id": "wiki20220301en303_13536", "title": "Placental site trophoblastic tumor", "score": 0.012066365007541479, "content": "Placental site trophoblastic tumor is a form of gestational trophoblastic disease, which is thought to arise from intermediate trophoblast.

The most common cause of worsening asthma in pregnancy is likely to be noncompliance with medication. Emphasizing to the patient in advance that fetal well-being is dependent on maternal well-being may help prevent this.In general, well controlled asthma is not associated with a higher risk of adverse pregnancy outcomes. Essential to successful asthma management is patient education that helps to ensure effective medication use, avoidance of triggers, and prompt treatment. This education should include measurement of peak expiratory flow rate and a written asthma action plan. Most of the medications that are used to control asthma in the general population can be safely used in pregnant women. Inhaled beta-adrenoceptor agonists (beta-agonists), cromolyn sodium (sodium cromoglycate), and inhaled and systemic corticosteroids all appear to be very well tolerated by the fetus. Budesonide and beclomethasone should be considered as the preferred inhaled corticosteroids for the treatment of asthma in pregnancy. Use of the leukotriene receptor antagonists zafirlukast and montelukast in pregnancy is probably safe but should be limited to special circumstances, where they are viewed essential for asthma control. Zileuton should not be used in pregnancy.Acute asthma exacerbations in pregnant women should be treated in a similar manner to that in non-pregnant patients. Maternal blood glucose levels should be monitored periodically in pregnant women receiving systemic corticosteroids because of the deleterious effects of hyperglycemia upon embryos and fetuses. During pregnancy, maternal arterial oxygen saturations should be kept above 95% if possible for fetal well-being. Ambulatory oxygenation should be checked prior to discharge to ensure that women do not desaturate with their daily activities.Acute exacerbations of asthma during labor and delivery are rare. Dinoprost, ergometrine, and other ergot derivatives can cause severe bronchospasm, especially when used in combination with general anesthesia, and should be avoided in asthmatic patients.

Significantly fewer children discontinued therapy with budesonide inhalation suspension than with placebo because of worsening asthma symptoms in a study that included children who were receiving inhaled corticosteroids at baseline. Recent evidence indicates that budesonide inhalation suspension is significantly more effective than nebulised sodium cromoglycate in improving control of asthma in young children with persistent asthma. At a dosage of 2 mg/day, budesonide inhalation suspension significantly reduced the number of asthma exacerbations and requirements for systemic corticosteroids in preschool children with severe persistent asthma. In children with acute asthma or wheezing, the preparation was as effective as, or more effective than oral prednisolone in improving symptoms. In children with croup, single 2 or 4mg dosages of budesonide inhalation suspension were significantly more effective than placebo and as effective as oral dexamethasone 0.6 mg/kg or nebulised L-epinephrine (adrenaline) 4mg in alleviating croup symptoms and preventing or reducing the duration of hospitalisation. Early initiation of therapy with budesonide inhalation suspension 1 mg/day appears to reduce the need for mechanical ventilation and decrease overall corticosteroid usage in preterm very low birthweight infants at risk for chronic lung disease. In adults with persistent asthma, budesonide inhalation suspension &lt; or =8 mg/day has been compared with inhaled budesonide 1.6 mg/day and fluticasone propionate 2 mg/day administered by metered dose inhaler. Greater improvements in asthma control occurred in patients during treatment with budesonide inhalation suspension than with budesonide via metered dose inhaler, whereas fluticasone propionate produced greater increases in morning peak expiratory flow rates than nebulised budesonide. Several small studies suggest that the preparation has an oral corticosteroid-sparing effect in adults with persistent asthma and that it may be as effective as oral corticosteroids during acute exacerbations of asthma or chronic obstructive pulmonary disease. The frequency of adverse events was similar in children receiving budesonide inhalation suspension 0.25 to 2 mg/day or placebo in 12-week studies. During treatment with budesonide inhalation suspension 0.5 to 1 mg/day in 3 nonblind 52-week studies, growth velocity in children was generally unaffected; however, a small but statistically significant decrease in growth velocity was detected in children who were not using inhaled corticosteroids prior to the introduction of budesonide inhalation suspension.

Sadly, this is sometimes encouraged by insufficiently educated physicians. Since the incidence and the prevalence of asthma is increasing, it is important to arouse the importance of proper asthma therapy during pregnancy. Inadequate therapy, as well as interrupting or discontinuing therapy, may result in adverse perinatal outcomes for both mother and child. The main goal of asthma control during pregnancy is control of symptoms and prevention of exacerbations, same as in every asthmatic, but even more important. Maintaining optimal lung function, as well as regular daily activities, ensures maintenance of optimal fetal oxygenation. The therapy should be adapted depending on the frequency and severity of daily and nocturnal symptoms, demand for reliever therapy, by the limitations in everyday activities and the frequency of emergency asthma-related hospitalizations. Pre-conceptual education and therapy are very important and should be supported by an asthma action plan adjusted for the period of pregnancy. It is very important to note that most of the drugs used before pregnancy can be safely continued during pregnancy. Pharmacological and non-pharmacological therapy should be used in parallel. Pregnant women should be informed about the nature of the disease, therapy used during pregnancy, possible complications, avoidance of triggers, proper administration of therapy and, most important, why should the therapy be continued throughout the pregnancy on individual basis. Although drug treatment should be based on using drugs with less harm risk, if control of severe symptoms is needed to be achieved in order to protect both mother and child, any anti-asthmatic drug would have the beneficial benefit/harm ratio. There is no solid evidence that asthma treatment during pregnancy causes adverse outcomes for the mother and child but for many, especially new drugs, there is not enough data gathered. On the other hand, harmfulness of uncontrolled asthma during pregnancy is well documented so every effort should be put on preserving good control of asthma during pregnancy." } ] } } }

It refers to a thyroid nodule, and the indicated test is a FNA (fine needle puncture). I have read the answer Emilio has written on the challenge; the question is in the endocrine block and it seems he is trying to make it clear that it is a nodule. Ultrasound facilitates FNA but is not mandatory, a 2 cm thyroid nodule can be punctured without echo. It is important to have an analysis of thyroid function prior to the puncture; but since he is talking about an asymptomatic patient, it seems clear that she is not hyperthyroid. I do not think it is contested and I think it is a question that most will have answered well.

A 56-year-old woman was referred to our center for evaluation of a 15-mm right lateral cervical neck mass which was strongly hypoechoic, not homogenous and contained several microcalcifications. There was no family history of thyroid disease, the patient was euthyroid and was not taking medications for thyroid disorders. On physical examination the thyroid was slightly enlarged and was normal on ultrasound except for a 1 x 3 mm hypoechoic nodule in the middle of the left lobe.

A lymph node metastasis from a papillary thyroid microcarcinoma (micro-PTC) was the presumptive diagnosis with the preoperative staging being Tx N1b. The patient underwent total thyroidectomy and bilateral lymph node dissection. At pathology, the right cervical mass was confirmed as lymph node metastasis of a PTC, and a unifocal micro-PTC was found in the middle left lobe.

She denied fevers, chills, night sweats or cough. Her symptoms were unresponsive to a course of oral dicloxacillin. The neck mass enlarged over 8 weeks and she was referred to our institution for evaluation. CT scan of the neck showed an enlarged lymph node. Ten days prior to her presentation in dermatology, a fine needle aspirate of the enlarging lymph node revealed necrotizing granulomas. Tissue was sent for routine mycobacterial and fungal cultures. Routine blood work, chest radiograph, and a tuberculin skin test were also performed. At the time of her dermatology visit she described the development of multiple new painful, non-pruritic lesions, bilaterally on the lower extremities. She also reported a red crusted area that appeared at the site of her tuberculin test that was placed subsequent to the development of her lower extremity lesions. Her past medical history was significant for Parkinson's disease, hypothyroidism and hypertension. Her current medications included l-thyroxine, estrogen and diltiazem. Her travel history was only remarkable for a trip to Jamaica the previous spring. She was born and raised in Haiti. She reported a history of a positive tuberculin skin test 20 years ago, but received no therapy. Physical examination revealed a 2 x 3 centimeter firm, nontender left lateral neck mass (Fig. 1). Her right forearm revealed an erythematous, ulcerated, indurated plaque 1.5 cm in diameter (Fig. 2.). Her lower extremities revealed tender 0.5 to 1 cm erythematous nodules below the knees bilaterally (Fig. 3). A punch biopsy of a lower extremity nodule revealed a mild pervisacular dermal infiltrate. Within the subcutaneous tissue there was septal widening. There was also a lymphohistiocytic infiltrate with a slight admixture of neutrophils within the septa of the fat lobules. There was no evidence of necrotizing vasculitis or collagen necrosis. An acid-fast stain was not performed. The histologic findings were consistent with a diagnosis of erythema nodosum. Her laboratory evaluation including CBC, electrolytes, thyroid studies, angiotensin converting enzyme level and chest radiograph were normal. Approximately 1 week after her dermatological evaluation, the fine-needle aspirate culture grew Mycobacterium tuberculosis. A diagnosis of tuberculous lymphadenitis associated with erythema nodosum was confirmed. The patient was started on quadruple therapy of isoniazid, rifampin, ethambutol and pyrazinamide.

Twenty-five smears performed by ultrasound-guided FNAB on laterocervical nodes with a 21-23 gauge needle were evaluates. All smears were stained according to Papanicolaou and microscopically examined. Of these 25 smears, 15 were diagnostic and 10 were non diagnostic. Of the 15 diagnostic cases, 10 were positive for metastatic lesions from thyroid neoplasm and the other 4 were classified as reactive lymphoadenitis. One smear for each case was selected for the immunohistochemical stain. All the 10 non-diagnostic cases showed no reaction to thyreoglobulin. Neoplastic cells, from 9 out of 11 cytologically positive smears, expressed thyreoglobulin in the cytoplasm. In one case no reaction was evident and the other one was discarded for technical reasons. In 3 of the 4 cases cytologically classified as lymphoadenitis, immunoreactive thyreoglobulin was not found. In the fourth case, blastic-like cells showed a scanty cytoplasmic rime which was immunoreactive for TG and thus was classified as a metastatic tumour. On this basis, it is suggested that FNAB should be performed routinelly in the diagnostic evaluation of neck masses of unknown origin in patients with a previous history of thyroid neoplasm.

It is defined as an exocrine pancreatic neoplasia that mainly affects women between the second and third decade of life, and its management is not well defined. Endoscopic ultrasound offers a key anatomical advantage in accessing the pancreas and endoscopic ultrasound fine-needle aspiration has become the gold standard method for the diagnosis of pancreatic lesions. Case 1: A 31-year-old white Hispanic woman presented with epigastric pain for 5 months. An abdominal ultrasound revealed a single 2 cm nodule in the uncinate process of her pancreas. Endoscopic ultrasound showed a regular, well-defined solid lesion with alternating cystic areas at the uncinate process of her pancreas, measuring 1.7 × 1.4 cm; endoscopic ultrasound fine-needle aspiration was then performed with cytopathological analysis compatible with solid pseudopapillary tumor. Body computed tomography confirmed the absence of metastases and she underwent conventional duodenopancreatectomy. However, she died 4 days after surgery due to postoperative surgical complications. Case 2: A 35-year-old Hispanic woman presented with left upper quadrant abdominal pain for 3 months, associated with a palpable mass at this region.

Endoscopic ultrasound fine-needle aspiration was performed and cytopathological analysis was suggestive of a pseudopapillary solid tumor. She underwent a body-tail laparoscopic pancreatectomy with splenectomy. Nine months after the diagnosis, she remains asymptomatic, continuing regular follow-up in the oncology out-patient clinic.

The core biopsy was not suggestive of malignancy but showed granulomatous inflammation. She had a wide local excision of the breast lump and an axillary lymph node biopsy. Histopathology and immunohistochemical studies excluded carcinoma or lymphoma but suggested the possibility of intramammary and axillary toxoplasmic lymphadenopathy. The results of Toxoplasma gondii IgM and IgG serology tests were positive, supporting a diagnosis of toxoplasmosis. Toxoplasmosis rarely presents as a pseudotumor of the breast.

Cervical spine x rays suggested a Hangman's fracture of C2 with slight anterior subluxation of C2 on C3 and a kyphus at that level. Computerized Tomography demonstrated no significant canal encroachment. An isotope bone scan was non-diagnostic. She was treated in a moulded cervical collar with neck held in slight extension.

An ultrasound-guided fine-needle aspiration was done in 67 patients with 83 suspicious enlarged CLNs to obtain material for cytology and Tg measurement in the needle washout, using an immunometric chemiluminescent assay. Measurement of anti-Tg antibodies (FNA-TgAb) was also carried out in half of all the aspirates. Subjects were divided into two groups: one of 16 patients awaiting thyroidectomy and the other of 51 patients in follow-up after surgery. The first group of patients had positive FNA biopsy (FNAB-Tg) in 14 out of the 18 studied CLNs with a range of 3.2-43 352 ng/ml, while FNAB-cytology indicated metastasis in only 8 out of the 14 CLNs with positive histology. A total of 65 CLNs were studied in the follow-up group. Lymphadenectomy was performed in 23 patients and 28 aspirated CLNs were removed. Histology confirmed the diagnosis of metastasis suggested by FNAB-Tg in 20 CLNs and of reactive lymphadenitis in the remaining 8 CLNs. FNAB-cytology was positive in only 11 CLNs. Sensitivity of FNAB-Tg was not affected by the studied FNAB-TgAb. The FNAB-Tg achieved a sensitivity of 100% in both groups. FNAB-Tg is an easy and inexpensive technique which proved to increase the diagnostic of cytology in the early diagnosis of papillary carcinoma recurrence to CLN even in the presence of serum TgAb." }, { "id": "pubmed23n1104_15002", "title": "Redifferentiation of BRAF V600E-Mutated Radioiodine Refractory Metastatic Papillary Thyroid Cancer After Treatment With Dabrafenib and Trametinib.", "score": 0.009345794392523364, "content": "Radioactive iodine-refractory metastatic differentiated thyroid cancer (RAIR) is associated with a poor prognosis.

Mammography revealed no evidence of malignancy in the left breast. In the right breast, at the 7 o'clock position, a loose cluster of faint calcifications spanned a 2.2-cm area. Ultrasound confirmed an irregular hypoechoic mass in the right breast measuring 3.5 × 2.7 × 2.8 cm. Ultrasound of the right axilla identified two enlarged right axillary lymph nodes. Ultrasound core-needle biopsy of the suspicious right breast mass confirmed invasive ductal carcinoma, nuclear grade 2, Ki67 index of 55%, estrogen receptor-positive (H score of 180), progesterone receptor-positive (H score of 135), HER2-positive (3+ on immunohistochemistry). Utilizing the TNM (tumor, node, metastasis) staging system, she was clinically staged with a stage IIB (cT2, cN1, M0) invasive breast tumor. The computerized axial tomography (CT) scan of the chest, abdomen, and pelvis demonstrated the known right breast mass and two enlarged right axillary lymph nodes; however, no metastatic disease was noted. Nuclear bone scan revealed no bone metastases. Her medical oncologist recommended she receive neoadjuvant chemotherapy. The patient was treated with 6 cycles of neoadjuvant docetaxel at 75 mg/m², carboplatin at an AUC (area under the curve) of 6, and trastuzumab (Herceptin) at 6 mg/kg (TCH), which she tolerated well. She then underwent a right segmental mastectomy with axillary lymph node dissection and was found to have a residual 1.0-cm invasive ductal carcinoma, representing a 60% tumor volume reduction. None of 13 axillary lymph nodes were positive for disease. Pathologic staging confirmed a stage IA (ypT1, ypN0, M0) tumor. DE completed 33 fractions of radiation therapy to the right breast. She initiated endocrine therapy with tamoxifen at 20 mg daily and received 1 year of maintenance trastuzumab (6 mg/kg). Due to vaginal discharge and weight gain, endocrine therapy was switched from tamoxifen to toremifene (Fareston), which she tolerated relatively well. She continued routine follow-up, with no evidence of disease. In September 2014, DE presented to her primary care physician complaining of left hip pain. Magnetic resonance imaging (MRI) of the left hip revealed T2 hyperintense masses within the right anterior superior iliac crest, right sacrum, and left iliac body consistent with skeletal metastases. She was referred back to her medical oncologist, and per National Comprehensive Cancer Network (NCCN) guidelines, a biopsy of the suspicious lesion was obtained. The bone biopsy of the lytic lesion was consistent with metastatic breast cancer, which was estrogen receptor-positive, progesterone receptor-positive, and HER2-positive (3+ on immunohistochemistry). Restaging CT scan of the chest, abdomen, and pelvis revealed new 4- to 6-mm pulmonary nodules, hilar and mediastinal lymphadenopathy, new liver lesions, and bone lesions. Nuclear bone scan confirmed multiple bone metastases of the right and left iliac bones and sternum. Complete blood cell count with differential and complete metabolic panel were within normal ranges.

An 82 years-old woman presented for the recent growth of a right thyroid nodule, diagnosed 3 years before, when a fine needle aspiration biopsy found a benign cytology suggesting a well-differentiated follicular thyroid adenoma. Her medical history included type 2 diabetes mellitus, atrial fibrillation and a right nephrectomy for a clear cell renal carcinoma done 16 years before. The patient has lost weight but she was otherwise asymptomatic. The right lobe goiter was painless, firm, and mobile with deglutition, without signs of local compression or latero-cervical lymphadenopathy. Thyroid ultrasonography revealed an enlarged (9.9 cm) macronodular right lobe, with multiple cystic areas, with normal left lobe and a thrombus in the right internal jugular vein. Thyroid function tests were normal. The patient was suspected of thyroid carcinoma and underwent a near total thyroidectomy. Histopathological examination revealed a metastasis of clear cell renal carcinoma in the right thyroid gland lobe (8.5/5/5 cm). Further imaging showed no primary tumor or other metastases.

Histopathology from the nodule on the jawline showed abundant foamy histiocytes in the dermis with few multinucleated giant cells and lymphocytes (Figure 2). The foamy histiocytes were periodic acid-Schiff-positive. On immunohistochemistry, histiocytes were CD68-positive. Findings of routine investigations including hemogram, peripheral blood smear, and blood chemistry were normal. Radiography of the lumbosacral spine showed mixed osteolytic and osteosclerotic lesions involving L5-S1, the left sacroiliac joint, and the left iliac blade. Findings from radiography of the long bones and skull were normal. Contrast-enhanced computed tomographic scan of the abdomen and pelvis showed areas of osteolysis, with marginal sclerosis present bilaterally that involved the iliac blades and the right half of the sacrum. A methylene diphosphate bone scan revealed increased tracer uptake seen at the fifth lumbar vertebrae, bilateral sacroiliac bone, and left iliac bone and areas of photopenia in sacrum. Bone marrow aspiration from the sternum showed normal cells with a normal erythroid-to-myeloid ratio. Ultrasonographic B scanning of the eyes showed no retro-orbital involvement.

In addition, little is known on the pathological features of the tumors that occur in DH cases and on their family history of cancer. Four carriers of pathogenic mutations in both BRCA1 and BRCA2 were identified among women who underwent genetic counseling for hereditary susceptibility to breast and ovarian carcinoma at three different Italian institutions. Clinical, pathological, and family history data were collected from medical records and during genetic counseling sessions. All identified DH cases developed breast carcinoma and three of them were also diagnosed with ovarian carcinoma. Mean ages of breast and ovarian cancer diagnosis were 42.7 and 48.6 years, respectively. The majority of breast cancers showed a BRCA1-related phenotype, being negative for hormone receptors and HER2. Two cases reported different gastrointestinal tumors among relatives. Although the individuals described in this study show more severe clinical features in comparison to previously reported BRCA1 and BRCA2 DH cases, our observations support the hypothesis of a non specific phenotype of DH cases in terms of age of disease onset. In addition, our observations indicate that in DH patients breast carcinogenesis appears to be driven mainly by the mutations in BRCA1.

The influence of prior exposure to estrogen replacement therapy (ERT) in postmenopausal patients or oral contraceptives (OC) in pre- and perimenopausal patients on tumor ERP was analyzed controlling for family history: none, first degree (1 degree, mother or sister), second degree (2 degrees, grandmother or aunt), or both 1 degree and 2 degrees relatives. The results showed no influence of the prior use of ERT in postmenopausal women on subsequent tumor ERP. Among pre- and perimenopausal women, those with a family history of breast cancer in only a 1 degree relative, showed a borderline significant association between prior OC usage and subsequent tumor ERP. The use of OC was consistently associated with ERP negative tumors (9/9) whereas of 29 patients who had no prior OC exposure 17 had ERP negative tumors (P = 0.04, Fisher's Exact Test). Analysis of the prior exposure to OC, verified with the primary care physician or pharmacist, showed that these patients first used OC at the mean age of 32.2 years, had used OC for a mean duration of 41.9 months and stopped OC use a mean of 79.5 months before being diagnosed as having breast cancer. These results suggest that in a subset of patients with breast cancer, and a first degree relative only who had breast cancer, prior exposure to OC may influence the subsequent ERP status of the tumor. This is not due to exogenous estrogen saturation of receptors as there was a long latent period between exposure and diagnosis. Alternative hypotheses as to the mechanism of selection of subsequent tumor ERP may be either inhibition of ERP positive preneoplastic or tumor cell clones early in the evolution of the tumor or early selection of a tumor capable of endogenous estrogen synthesis with receptor saturation." }, { "id": "pubmed23n0976_164", "title": "BRCA1/BRCA2 mutations in Japanese women with ductal carcinoma in situ.", "score": 0.011616161616161616, "content": "Ductal carcinoma in situ (DCIS) is considered a component of the clinical spectrum of breast cancer even in those with BRCA1/2 mutation.

Since 2010, three new oral anticoagulants have received Food and Drug Administration approval for stroke prevention in atrial fibrillation. This review summarizes data from three landmark trials: RE-LY, ROCKET-AF, and ARISTOTLE. In addition, issues relating to cost, reversal, drug interactions, and perioperative discontinuation are discussed. Compared to Warfarin, Dabigatran 150 mg twice daily lowered the primary outcome of stroke/systemic embolism by 34% (number needed to treat/yr 169) and had similar incidence of major bleeding. Rivaroxaban demonstrated non inferiority compared to the warfarin group for the primary outcome of stroke and systemic embolism and major bleeding. Apixaban showed a relative risk reduction for the primary outcome of 21% (number needed to treat 300), and lowered major bleeding down by 31% (number needed to treat /yr 104).

The efficacy of anticoagulation for primary prevention of stroke or transient ischaemic attacks (TIAs) in patients with NVAF has been established by prospective, randomised and controlled trials. Warfarin decreased the frequency of all strokes by 68% and the rate of the combined outcome of stroke, systemic embolism or death by 48%. Anticoagulation with warfarin using international normalised ratios (INRs) ranging from 2.0 to 3.0 is recommended for patients with NVAF, who have any of the risk factors identified by the Atrial Fibrillation Investigators (AFI) [previous stroke or TIA, history of hypertension, diabetes mellitus, advanced age (&gt; or = 65 years old), congestive heart failure and coronary artery disease], the American College of Chest Physicians (ACCP) [increased age (&gt; 75 years old), prior stroke, hypertension and heart failure], or the Stroke Prevention in Atrial Fibrillation (SPAF) investigators [women &gt; 75 years old, prior stroke, systolic blood pressure &gt; 160mm Hg, recent heart failure, and fractional shortening &lt; 25% on echocardiography]. For the secondary prevention of stroke, the efficacy of adjusted-dose warfarin therapy has been demonstrated by 2 major randomised trials. SPAF III (INR 2.0 to 3.0) demonstrated a lower incidence of ischaemic stroke or systemic embolism (3.4 %/year) compared with low fixed-dose warfarin plus aspirin (acetylsalicylic acid) [11.9%]. The European Atrial Fibrillation Trial [EAFT] (INR 2.5 to 4.0) showed a lower incidence of all stroke (4.0 %/year) with adjusted-dose warfarin compared with placebo (12.0 %/year). The incidence of major bleeding in the adjusted-dose warfarin group in SPAF III and EAFT was 2.4 and 2.8 %/year, respectively. EAFT incidence rates for the occurrence of a first ischaemic or haemorrhagic complication analysed by INR range indicated that the rate was lowest at INRs of 2.0 to 2.9, and higher with INRs of 3.0 to 3.9. Therefore, the optimal intensity of anticoagulation for prevention of recurrent stroke seems to be an INR of between 2.0 and 3.0, as for primary prevention. Retrospective and prospective studies from Japan reported that in the elderly, haemorrhagic complications occur frequently with INRs above 2.6 and major ischaemic events cannot be prevented at INRs below 1.6. Therefore, an INR target between 1.6 and 2.6 may be an alternative for secondary prevention of stroke in elderly patients with NVAF who have a potential risk of bleeding, to avoid both major ischaemic and haemorrhagic events. Antiplatelets may be administered in patients who are unable to manage taking warfarin properly or who have a high risk of falling and subsequently sustaining a head injury, although the efficacy of antiplatelets for secondary prevention of stroke in NVAF has not yet been established." }, { "id": "wiki20220301en293_5623", "title": "Management of atrial fibrillation", "score": 0.014488146062312654, "content": "Chronic anticoagulation Among patients with nonvalvular AF, anticoagulation with warfarin can reduce stroke by 60% while antiplatelet agents can reduce stroke by 20%.

Prophylactic colectomy reduces the risk of death from colorectal cancer to such an extent that late sequelae such as upper gastrointestinal tumours have become the main cause of mortality in appropriately managed patients. The age at which colonic surveillance begins reflects the natural history of the disease. Onset of polyp formation and cancer in childhood is very unusual, but has recently been associated with a specific mutation at codon 1309 in exon 15 where a more severe phenotype is sometimes observed. The case histories of two families are reported in which there is childhood onset of polyps in the youngest generation and in one case a carcinoma, in whom mutations have been identified in exon 11 of the APC gene. Several other affected relatives were diagnosed at ages ranging from 5-48 years, some already with a cancer at the time of first screening. Since the aim of screening for colonic polyps is prevention of colonic cancer, family members at risk should be offered genetic assessment and direct mutation testing where this is possible, usually in the early teens. In the absence of a genetic test (the situation in about one third of families) or in a known gene carrier, annual colonoscopy examination is advised from the same age.

This familial clustering in about 10-20% of colorectal cancers has implications for screening because the immediate family members of a patient with apparent sporadic colorectal cancer have a twofold to threefold increased risk of the disease. The magnitude of the risk depends on the age at diagnosis of the index case, the degree of kinship of the index case to the at-risk case, and the number of affected relatives. In addition to screening the easily identifiable high-risk groups such as FAP and HNPCC, care should be taken to recognize intermediate-risk patients and to provide them with appropriate screening recommendations. Because the molecular basis and the natural history of these intermediate-risk patients are largely unknown, screening recommendations are as yet more empirical. If a person has a first degree relative with colon cancer, average risk colon cancer screening is recommended, but starting at age 40 years. The decreased age is given because the risk at age 40 for those with an affected first-degree relative is similar to the risk at age 50 for the general population.

Families with one or more first-degree relative affected under 50 years of age = an extra 3 points. Families with one or more second-degree relative affected under 50 years of age = an extra 1 point.

A control group of average-risk patients having screening colonoscopy was used. Categories were compared in number of adenomas, hyperplastic polyps, and cancers.

Correlational analyses indicated that, with the exception of the two mood-related items, noncognitive symptoms on the ADAS were not highly correlated with one another. Only one of the noncognitive items, concentration, was strongly correlated with the severity of cognitive impairment. On average, patients showed progressively worse cognitive functioning over time as measured both by the ADAS-Cog and the BIMC. The mean severity of noncognitive symptoms did not change during the course of a 5-year follow up. The severity of behavioral disturbance at any one evaluation was negatively correlated with change in behavior during the next 6 months and was not correlated with cognitive decline. Mild behavioral disturbances are common, whereas moderate to severe behavioral symptoms are less frequent in this population of AD patients. Disturbances in mood and manifestations of agitation and psychotic symptoms are not closely related to one another and show little progressive worsening over time.

This report illustrates that some types of attention-deficit/hyperactivity disorder may be misdiagnosed as dementia. The patient was a 58-year-old woman. Although she presented with a tendency for inattentiveness and forgetfulness since childhood, she did not have a history of psychiatric disorders prior to consultation. Around the age of 52 years, her inattentiveness and forgetfulness gradually progressed, and at 57 years of age, she became inattentive and forgetful that it interfered with her work and daily life. For example, she forgot meetings with important clients and transferred money to the wrong bank account; these failures resulted in poor management of her company. At home, she experienced increasing difficulties with remembering prior commitments with her family and misplacing items, which her family members noticed. With the encouragement of her family and employees, who worried that she was suffering from dementia, she visited our memory clinic, whereby she was suspected of having early onset Alzheimer's disease.

After dismissing various possible diagnoses, including dementia, other organic diseases, mood disorders, and delirium, we diagnosed her with attention-deficit/hyperactivity disorder. Treatment with 18 mg of methylphenidate was initiated, and significant improvements in her symptoms were observed within a few days; for example, she stopped losing her things, was able to concentrate for long durations, and could complete more tasks than she could before treatment. Since initiating treatment, she has returned to work and has been able to perform her daily activities without difficulty. This case supports that some patients with late-onset attention-deficit/hyperactivity disorder may gradually develop dementia-like symptoms during the pre-elderly and elderly stages of life.

Depression is known to be a complication of brain tumours and may sometimes be seen after the presentation of neurological symptoms linked to brain tumours, and sometimes after tumor treatment (Oğuz et al. 2005, Litofsky et al. 2004, Moise and Madhusoodanan 2006, Oreskovic M et al. 2007, Rooney A et al. 2010). The dorsolateral prefrontal, orbitofrontal and medial frontal circuits constitute the three subcortical neuronal circuits in the frontal cortex. The dorsolateral prefrontal circuit is associated with planning and operational functions and lesions on it may give rise to apathy, abulia, perseveration, personality changes and planning disorder. Lesions involving the orbitofrontal circuit, which is associated with response suppression and disinhibition, may involve emotional lability and memory problems. Whereas lesions affecting the right orbitofrontal circuit give rise to elevated mood, lesions on the left orbitofrontal circuit lead to depressed mood. In cases with medial frontal circuit involvement, akinetic mutism may result from lesions in the superior medial region and anteroretrograde amnesia and confabulation are observed with lesions in the inferior medial region (Tosun et al. 2016, Chirchiglia 2018). A diagnosis of psychiatric disorder may be given during the first examination of patieants with primary brain tumours, especially if localized in the frontal lobe. Thorough history taking and physical examination are necessary for early diagnosis. The case reported here concerns a 29-year-old university graduate female patient, living with her partner and children, who consulted the clinic with complaints of tendency to frequent crying, anhedonia, having difficulty with speech fluency, forgetfulness and distractedness that had presented suddenly, 2 months previously, without any causative stressor.

She was fully conscious and oriented, not willing to cooperate with the interview, had distinct difficulty in maintaining attention and with fluency of speech. Her mood was depressive. She described loss of appetite, fatigue and energy loss. Her difficulty in paying attention was pronounced. She did not have a history of psychotropic medication use or family history of psychiatric disease. She did not smoke or use alcohol or substance. After evaluating the clinical interview, a preliminary diagnosis of major depressive disorder was considered on the basis of the DSM-5 criteria. Routine blood tests were requested. Given the continuation of her complaints, the difficulty with fluent speech and the increase in tendency to sleep at the first week follow up, cranial MRI was planned. The MRI results showed on the right, in the frontal lobe a multilocular mass with precallosal extension, undiscernable margins with the right lateral aspect of the corpus callosum genu and dispersed cystic-necrotic areas with T2 signal series. The dimensions of the mass were nearly 5 x 3 cm causing a 1-cm right-to-left shift of the midline (Figure 1) DEPRESSION AS THE FIRST SYMPTOM OF FRONTAL LOBE GRADE 2 MALIGNANT GLIOMA 2 Türk Psikiyatri Dergisi 2 Turkish Journal of Psychiatry Letter to the Editor 143 144 The patient was referred for surgery with the preliminary diagnosis of high-grade glial tumour. Pathology results identified a grade 2 glioma. It was learned that radiotherapy sessions were begun after surgery. The patient did not have any symptoms of psychopathology during the 2 monthly psychiatric interviews made after surgery. Brain tumours generally indicate their presence with headache, seizures and other neurological symptoms and very rarely with depression as seen in the case of our patient. It should be kept in mind that atypical psychiatric symptoms may have an underlying organic lesion and subtle neurological symptoms should be investigated in detail. A recent meta-analysis on 37 observational studies determined a 21.7% prevalence of depression in a total of 4518 patients with intracranial tumours. Comorbidity of depression with brain tumor was demonstrated to worsen the quality of life, increase suicidal risk and lower the chance of survival (Huang et al. 2017). The possibility of psychiatric symptoms being the clinical clues for brain cancer was noted and the necessity of neuroimaging tests in cases of recent-onset psychosis or mood disorder symptoms, atypical personality changes and anorexia without body dysmorphic disorder was emphasized (Madhusoodanan et al. 2015). Loss of interest, tendency to frequent weeping, introversion and anhedonia were the sole complaints in the case discussed here. The increase in psychomotor retardation and slowing down of movements at the very first weekly control follow up necessitated neuroimaging. Despite the reports in the literature on the frequent association of unpreventable excessive behavior, disinhibition and irritability with right frontal injury and lesions (Okumuş and Hocaoğlu 2018), depression was the dominant symptom in the case presented here. There are differences between primary major depression and depression presenting with underlying somatic diseases which is known to occur at later ages (Rouchell et al. 2002). However, our patient was aged 29 years. Also, cases of depression due to somatic disease are less associated with family history of depression and suicidal ideation and attempts, while cognitive symptoms come to the foreground during mental status examination. (Sertöz and Mete 2004, Rouchell et al. 2002). Our patient did not have suicidal ideation or attempts, or a family history of depression. In apathy, which may be explained as emotional blunting, indifference or detachment from the external world, targeted behavior is also reduced next to the lack of emotional expression. The individual discussed here was learned not to sit at the table or change the television channel unless reminded to do so. When the reason was asked, she could not think of one. The reduction in emotional expression accompanies reduced insight, abulia and lack of empathy (Sözeri Varma et al. 2019). In depression, apathy is defined as 'sorrowless depression'. Our patient cried but had very blunted mimics and gestures. She explained that she could not help weeping even at times when she did not feel internally distressed. The seriousness of apathy, as a symptom difficult to differentiate from depression, is still not understood.

Comparison of 45 individuals with depression due to aging and 43 healthy individuals showed apathy to be associated with fronto-limbic gray and white matter abnormalities which continued after antidepressant treatment. The structural anomalies of the posterior subgenual cingulate gyrus and the uncinate fasciculus were discussed (Yuen 2014). The case discussed here is presented to emphasize the importance of brain imaging methods and detailed investigation of atypical symptoms for diagnostic approaches to psychiatric disorders. Especially, complaints at young age of depression with psychomotor retardation, reduced fluency of speech and sudden onset withdrawal without stressors should be a warning of secondary depression.

Patients' scores on the Activities of Daily Living section of the questionnaire declined (bathe self, P = .03; transfer from bed or chair, P = .03; and groom self, P = .06). Significant deterioration in behaviors over time was found in incontinence (P = .04). Fewer patients were depressed at time 2 (P = .02). The patient behaviors found most troublesome at time 1 were worrying about memory loss, losing or hiding things, feeling blue, experiencing restlessness, having difficulty calculating, experiencing a lack of interest, and having false ideas. At time 2, the greatest problems were having a short attention span, failing to recognize persons or things, experiencing a lack of interest, experiencing restlessness, repeating himself or herself, forgetting where he or she is, speaking incoherently, and being incontinent. Questions caregivers most wanted answered at time 1 concerned possible treatment, the future course of illness, and the cause of the symptoms. At time 2, the concerns were the future course of illness, possible treatment, and disease inheritance. There was significantly more interest in family agreement about care (P = .004) and the need for legal guardianship (P = .001) at time 2. Caregivers' perceptions of the most frequent and troublesome behaviors of patients with dementia were documented at different stages of the disease.

Alzheimer’s disease (AD) is a fatal disease that continuously deteriorates brain chemistry over time. Accounting for more than 60% of the dementia in older people, AD gradually leads to detrimental effects on cognitive function, linguistic abilities, and memory. Within populations living with Alzheimer's, music therapy is sometimes used to assist in palliating the behavioral and psychological symptoms of this disease. Music therapy is based in scientific findings and can elicit change in individuals as well as groups through music.

Progression over time may or may not be typical, suggesting alternate diagnoses such as Lewy body or frontotemporal dementias. Apolipoprotein E genotype does not appear to be useful as a diagnostic marker. The usefulness of brain imaging in AD must be reexamined. Critical events in the natural history of AD, such as institutionalization and loss of ability for self-care, could be used as end points. Loss of ability for instrumental tasks, such as driving, traveling alone, or managing finances, would be preferable for early-stage stabilization studies. Different symptomatic domains of AD (mood, cognition, functional autonomy, behavior, motoricity) can be quantified using specific outcome measures. Although cognitive loss has been considered a core symptom of AD from a regulatory perspective, loss of functional autonomy and behavioral disinhibition are considered more important by clinicians and families. Recently, the availability of new scales has led to an interest in all of these domains. Results from symptomatic drug studies suggest a differential effect of cholinesterase inhibitors on cognition versus muscarinic agonists on functional autonomy and behavior. Hence there is a need to measure these domains separately and, eventually, to attempt combination therapy. Quality of life is a difficult but important dimension of AD therapeutic research, and it requires further methodological research." }, { "id": "pubmed23n1122_17394", "title": "Most families tend to realize progress of Alzheimer's disease when behavioural and psychological symptoms are obvious.", "score": 0.009174311926605505, "content": "Alzheimer's disease (AD) is a common cognitive disease that can progress at an accelerating rate.

Participants were 161 new outpatients with AD or mild cognitive impairment at four memory clinics whose AD stage was diagnosed using the Revised Hasegawa Dementia Scale (HDS-R) and Mini-Mental State Examination (MMSE). We classified patients into four groups according to AD severity. Family members completed the Functional Assessment Staging (FAST) scale during an interview. We then assigned patients to three groups according to discrepancies between family-assessed and diagnosed AD stage. Families also completed the Neuropsychiatric Inventory Questionnaire (NPI-Q), which assesses 12 neuropsychiatric domains, in order to examine the presence of BPSD in relation to AD stage. Most families (74%-80%) assessed patients as having milder AD than the diagnosed stage. NPI-Q scores and duration of education significantly affected discrepancies with HDS-R and MMSE scores. The NPI-Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance significantly affected family-assessed FAST. Families of patients with more years of education assessed the AD stage as more advanced than the diagnosed stage. Surprisingly, living together did not significantly affect the discrepancy. Most families assessed AD as milder than the clinically diagnosed AD stage. In addition, high NPI-Q scores and more years of school education significantly affected the discrepancy. Family-assessed FAST was significantly affected by the NPI-Q domains of anxiety, apathy/indifference, aberrant motor behaviours, and appetite/eating disturbance.

The correct answer is: 2. Hyperkalemia. Spironolactone, as a potassium-sparing diuretic, inhibits the action of aldosterone at the renal level, being responsible for a decrease in potassium excretion. Hyperkalemia produces repolarization disturbances that result in the installation of a large, symmetrical, narrow-based T, visible in the precordial leads. The QT space is shortened. These anomalies appear with a kalemia of around 5.5 to 6 mmol/l. Above 6.5 mmol/L, electrocardiographic changes are constant, and are dominated by conduction disturbances (making ventricular extrasystoles possible).

Patients presenting in cardiac arrest or who were referred for hyperkalemia or dialysis were excluded. Patient charts were reviewed to find whether patients received specific treatment for hyperkalemia and, if so, what clinical attributes were associated with the time to initiation of treatment.

Several cardiac and non cardiac drugs are known to suppress the HERG K⁺ channel and hence the I(K), and especially in the presence of hypokalemia, can result in prolonged action potential duration and QT interval, QTU alternans, early afterdepolarizations, and torsade de pointes ventricular tachyarrythmia (TdP VT). Hyperkalemia affects up to 8% of hospitalized patients mainly in the setting of compromised renal function. The ECG manifestation of hyperkalemia depends on serum K⁺ level. At 5.5-7.0 mmol/L K⁺, tall peaked, narrow-based T waves are seen. At &gt; 10.0 mmol/L K⁺, sinus arrest, marked intraventricular conduction delay, ventricular techycardia, and ventricular fibrillation can develop. Isolated abnormalities of extracellular calcium (Ca⁺⁺) produce clinically significant EP effects only when they are extreme in either direction. Hypocalcemia, frequently seen in the setting of chronic renal insufficiency, results in prolonged ST segment and QT interval while hypercalcemia, usually seen with hyperparathyroidism, results in shortening of both intervals. Although magnesium is the second most abudent intracellular cation, the significance of magnesium disorders are controversial partly because of the frequent association of other electrolyte abnormalities. However, IV magnesium by blocking the L-type Ca(⁺⁺) current can successfully terminate TdP VT without affecting the prolonged QT interval. Finally, despite the frequency of sodium abnormalities, particularly hyponatremia, its EP effects are rarely clinically significant." }, { "id": "wiki20220301en026_74327", "title": "Hyperkalemia", "score": 0.01778093883357041, "content": "Hyperkalemia is an elevated level of potassium (K+) in the blood. Normal potassium levels are between 3.5 and 5.0mmol/L (3.5 and 5.0mEq/L) with levels above 5.5mmol/L defined as hyperkalemia. Typically hyperkalemia does not cause symptoms. Occasionally when severe it can cause palpitations, muscle pain, muscle weakness, or numbness. Hyperkalemia can cause an abnormal heart rhythm which can result in cardiac arrest and death. Common causes of hyperkalemia include kidney failure, hypoaldosteronism, and rhabdomyolysis. A number of medications can also cause high blood potassium including spironolactone, NSAIDs, and angiotensin converting enzyme inhibitors. The severity is divided into mild (5.5–5.9mmol/L), moderate (6.0–6.4mmol/L), and severe (>6.5mmol/L). High levels can be detected on an electrocardiogram (ECG).

Prior to admission, the patient had increased licorice ingestion to a total of some 70 g daily. The licorice intake was stopped and potassium was administrated orally and intravenously. Plasma potassium normalized and the ECG changes remitted. To our knowledge a few other cases of licorice-induced pseudohyperaldosteronism and long QT interval have previously been reported. This underlines the importance of quantifying licorice intake in younger people with unexplained high blood pressure and low potassium. Even small amounts of licorice daily may increase the risk of developing hypertension; therefore, licorice should be asked for specifically. Even though licorice intake is very easy to cover in the patient's history, it is often missed. Excessive licorice intake may course severe hypokalemia causing long QT interval in the ECG recording, potentially progressing into arrhythmias and even cardiac arrest/sudden death. Hypokalemia &lt;3 mmol/L and present ECG changes should be treated with potassium intravenously.

This ECG concerns a 60-year-old male presented with general fatigue, weakness, epigastric pain, anorexia, nausea and extreme hypercalcemia (serum total and ionized calcium levels 20.5 mg/dL and 12.02 mg/dl, respectively), hypokalemia and hypomagnesemia associated with elevated parathyroid hormone (1160 pg/ml) and normal serum vitamin D level (97 ng/ml) . This rare manifestation of primary hyperparathyroidism has been named hyperparathyroid crisis in the literature. Hyperparathyroid crisis is an emergency form of multiple electrolyte abnormalities that manifest as a life-threatening hypercalcemia and simultaneous hypokalemia and hypomagnesemia; these two later are believed to be caused by diuretic effect of calcium on the renal tubules. The unique pattern of ECG in our patient first was misdiagnosed as prominent T waves with prolongation of the QT corrected (QTc) interval, which has been reported several times in patients with hyperparathyroidism crisis, compatible with our patient. But more investigation revealed that, the QTc interval not only is not prolonged, it is shortened as it is expected from the effect of hypercalcemia on electrocardiogram. The exact pattern of the patient`s ECG (figure 1) can be interpreted as it follows: (1) Flattening of the T wave, (2) a prominent U wave, (3) prolongation of the descending limb of the T wave such that it overlapped with the next U wave (4) virtual absence of ST segment and (5) shortening of the QT corrected interval. In conclusion, it should be emphasized when the T and U waves are separated by a very short segment they can mimic the appearance of a prolonged QT interval.

Long QT intervals predispose the patient to an , wherein the R-wave, representing ventricular depolarization, occurs during the relative refractory period at" }, { "id": "pubmed23n0475_2110", "title": "Electrocardiographic manifestations in patients with thyrotoxic periodic paralysis.", "score": 0.009615384615384616, "content": "Thyrotoxic periodic paralysis (TPP) commonly precedes the overt symptoms and signs of hyperthyroidism and may be misdiagnosed as other causes of paralysis (non-TPP). Because the cardiovascular system is very sensitive to elevation of thyroid hormone, we hypothesize that electrocardiographic manifestations may aid in early diagnosis of TPP. We retrospectively identified 54 patients who presented to the emergency department (ED) with hypokalemic paralysis during a 3.5-year period. Thirty-one patients had TPP and 23 patients had non-TPP, including sporadic periodic paralysis, distal renal tubular acidosis, diuretic use, licorice intoxication, primary hyperaldosteronism, and Bartter-like syndrome. Electrocardiograms during attacks were analyzed for rate, rhythm, conduction, PR interval, QRS voltage, ST segment, QT interval, U waves, and T waves. There were no significant differences in age, sex distribution, and plasma K+ concentration between the TPP and non-TPP groups. Plasma phosphate was significantly lower in TPP than non-TPP. Heart rate, PR interval, and QRS voltage were significantly higher in TPP than non-TPP. Forty-five percent of TPP patients had first-degree atrioventricular block compared with 13% in the non-TPP group. There were no significant differences in QT shortening, ST depression, U wave appearance, or T wave flattening between the 2 groups. Relatively rapid heart rate, high QRS voltage, and first-degree AV block are important clues suggesting TPP in patients who present with hypokalemia and paralysis." }, { "id": "pubmed23n0862_23184", "title": "Not your regular high: cardiac dysrhythmias caused by loperamide.", "score": 0.009523809523809525, "content": "Loperamide, a non-prescription anti-diarrheal agent, is a peripheral mu-opioid receptor agonist that is excluded from the blood-brain barrier by p-glycoprotein at therapeutic doses. Overdoses of loperamide penetrate the central nervous system (CNS), leading to abuse. We report cardiac conduction abnormalities and dysrhythmias after ingestion of a recreational supra-therapeutic dose of loperamide confirmed with an elevated blood loperamide concentration. A 48-year-old woman with a history of alcohol and benzodiazepine abuse presented to the emergency department (ED) with somnolence, weakness and slurred speech. She was taking 20 to 40 tablets of 2 mg loperamide 1-2 times/day for weeks along with clonazepam and whiskey. Vital signs were: blood pressure (BP), 124/90 mmHg; heart rate (HR), 88/min; respiratory rate(RR), 20/min; T, 36.9 °C; O2 saturation 100% on room air (RA). Glucose was 6.4 mmol/L. Electrocardiogram (ECG) had a ventricular rate of 58/min, QRS 164 ms, QT 582 ms with no discernable p-waves. Lactate was 3.5 mmol/L and potassium was 6.2 mEq/L. Labs were notable for an anion gap of 20 mEq/L, ethanol of 3.9 mmol/L, creatinine of 2.3 mg/dL and loperamide concentration of 210 ng/mL (average therapeutic plasma concentration 1.2 ng/mL). She became hypotensive, but responded to fluids. Following treatment for hyperkalemia with calcium, insulin, dextrose, and hypertonic sodium bicarbonate a repeat ECG had a ventricular rate of 66/min, QRS 156 ms, and QT 576 ms. Magnesium was given and pacer pads were placed. During the infusion of magnesium, her BP fell to 92/58 mmHg with a HR of 54/min, RR 14/min, O2 saturation of 97% on RA so the infusion was stopped. The ECG after the magnesium infusion had a ventricular rate of 51/min, QRS of 134 ms, and QT 614 ms. In the ICU she had multiple runs of non-sustained ventricular tachycardia that did not require therapy. Over the next 48 h she improved and was transferred to a floor bed. On day four of hospitalization the patient left against medical advice. At that time, her ECG showed sinus tachycardia with a heart rate 114/min, QRS 82 ms, QT 334 ms. Loperamide produces both QRS and QT prolongation at supra-therapeutic dosing. A blood loperamide concentration of 210 ng/mL is among the highest concentrations reported. Supra-therapeutic dosing of loperamide is promoted on multiple drug-use websites and online forums as a treatment for opioid withdrawal, as well as for euphoric effects. With the current epidemic of prescription opioid abuse, toxicity related to loperamide, an opioid agonist that is readily available without a prescription is occurring more frequently. It is important for clinicians to be aware of the potentially life-threatening toxicity related to loperamide abuse in order to provide proper diagnosis, management and patient education." }, { "id": "wiki20220301en031_37318", "title": "Hypovolemic shock", "score": 0.009433962264150943, "content": "Again, the above is outlined for a healthy 70 kg individual.

However, there is a paucity of evidence to support this practice. This study analyzes the association between specific hyperkalemic ECG abnormalities and the development of short-term adverse events in patients with severe hyperkalemia. We collected records of all adult patients with potassium (K+) ≥6.5 mEq/L in the hospital laboratory database from August 15, 2010, through January 30, 2015. A chart review identified patient demographics, concurrent laboratory values, ECG within one hour of K+ measurement, treatments and occurrence of adverse events within six hours of ECG. We defined adverse events as symptomatic bradycardia, ventricular tachycardia, ventricular fibrillation, cardiopulmonary resuscitation (CPR) and/or death. Two emergency physicians blinded to study objective independently examined each ECG for rate, rhythm, peaked T wave, PR interval duration and QRS complex duration. Relative risk was calculated to determine the association between specific hyperkalemic ECG abnormalities and short-term adverse events. We included a total of 188 patients with severe hyperkalemia in the final study group. Adverse events occurred within six hours in 28 patients (15%): symptomatic bradycardia (n=22), death (n=4), ventricular tachycardia (n=2) and CPR (n=2). All adverse events occurred prior to treatment with calcium and all but one occurred prior to K<sup+</sup-lowering intervention. All patients who had a short-term adverse event had a preceding ECG that demonstrated at least one hyperkalemic abnormality (100%, 95% confidence interval [CI] [85.7-100%]). An increased likelihood of short-term adverse event was found for hyperkalemic patients whose ECG demonstrated QRS prolongation (relative risk [RR] 4.74, 95% CI [2.01-11.15]), bradycardia (HR&lt;50) (RR 12.29, 95%CI [6.69-22.57]), and/or junctional rhythm (RR 7.46, 95%CI 5.28-11.13). There was no statistically significant correlation between peaked T waves and short-term adverse events (RR 0.77, 95% CI [0.35-1.70]).

It results from mutations in the HSD11B2 gene, which encodes the kidney isozyme of 11β-hydroxysteroid dehydrogenase type 2. In an unaffected individual, this isozyme inactivates circulating cortisol to the less active metabolite cortisone. The inactivating mutation leads to elevated local concentrations of cortisol in the aldosterone sensitive tissues like the kidney. Cortisol at high concentrations can cross-react and activate the mineralocorticoid receptor due to the non-selectivity of the receptor, leading to aldosterone-like effects in the kidney.

Severe hypokalemia resulting in muscle weakness and rhabdomyolysis has not been reported as a phenotypic feature of MtD. Here we describe a 60-year-old male patient who developed myalgias followed by generalized muscle weakness a few days before admission. Symptoms were attributed to severe hypokalemia that occurred after the patient had discontinued spironolactone, a competitive antagonist of the aldosterone receptor, four months earlier on his own judgment. Spironolactone was given for 10 years to treat suspected primary hyperaldosteronism (Conn's syndrome). He presented with myopathic face, bilateral ptosis, hypertelorism, brachydactylia, weakness of the axial and limb muscles, and bilateral leg edema. Hypertelorism and brachydactylia are known as physical traits of MtD. Laboratory investigations revealed hypokalemia of 1.7 mmol/l and elevated serum levels of creatine kinase (2,772 U/l). Electrocardiogram showed sinus rhythm, left bundle-branch-block, repolarization abnormalities, and prolonged QTc (571 ms), which is associated with a propensity to ventricular arrhythmias. Diagnostic work-up revealed bilateral adenomas of the suprarenal glands. Conn's syndrome was regarded as a manifestation of MtD, since MtDs are frequently associated with endocrine abnormalities. The patient also presented with occasional double vision, ptosis, renal insufficiency, bilateral renal cysts, hypertriglyceridemia, arterial hypertension, and hypertrophic cardiomyopathy. Taken together, we have made the diagnosis of MtD. In conclusion, MtD may be associated with adrenal adenomas, which may cause severe symptomatic hypokalemia, manifesting as generalized weakness and myalgias due to rhabdomyolysis. Endocrine involvement may be a phenotypic feature of MtD.

She had been treated with left atrial cryoablation a few weeks before admission and had been cardioverted a few days after the procedure because of relapse of atrial fibrillation. On admission, the patient had systolic blood pressure of 80 mm Hg and an ECG with broad QRS-complexes at 380 ms. We suspected intoxication and she was intubated to administer activated charcoal after gastric lavage. She was cardiovascularly unstable and in need of intravenous infusion of noradrenaline and adrenaline. Further investigations at her home suggested that she had poisoned herself with 4-5 g flecainide, 0.3 g oxazepam and 0.5 g meclizine. After administration of 500 mmol sodium bicarbonate and 5 mmol calcium chloride, the QRS complexes narrowed temporarily. On day 2, due to sustained bradycardia and hypotension despite receiving adrenergic medications, a temporary pacemaker was implanted, leading to improved heart rate and blood pressure. She experienced several complications including hypertensive pulmonary oedema, atrial fibrillation, extensively prolonged QT interval because of polypharmacy and Takotsubo cardiomyopathy. She was discharged from the hospital in good health on day 17. At a follow-up visit at the outpatient clinic 12 weeks later, cardiac function had normalised. The QT interval was now normal; however, there were persistent T-wave inversions in leads I, aVL and V4-6. Flecainide blocks sodium channels in cardiomyocytes. Intoxication with flecainide is rare, with mortality rates of about 10 %. Sodium bicarbonate in larger doses has been reported to stabilise patients with flecainide intoxication due to modification of the binding of flecainide to sodium receptors in cardiomyocytes, and due to alkalisation which makes flecainide detach from sodium receptors. Our patient had a temporary effect with narrowing of QRS complexes after receiving sodium bicarbonate. She also showed a beneficial effect from implantation of a temporary pacemaker, although earlier case reports have described problems with high thresholds and capture failure." } ] } } }
