title: Clinical and immunohistochemical study of melanotic neuroectodermal tumor of infancy in the maxilla

description: ABSTRACT Melanotic neuroectodermal tumor of infancy is a rare and fast-growing neoplasm. In this study, we describe the case of a 6-month-old female patient, who presented swelling in the anterior maxilla. Tomographic reconstruction showed an unilocular hypodense and expansive area associated with the upper right central primary incisor. The presumptive diagnoses were dentigerous cyst, adenomatoid odontogenic tumor, melanotic neuroectodermal tumor of infancy and rhabdomyosarcoma, and an incisional biopsy was performed. Microscopically, the lesion revealed a biphasic cell population, consisting of small, ovoid, neuroblastic-like cells and epithelioid cells containing melanin. Immunohistochemically, the melanocyte-like component was strongly and diffusely positive for HMB-45 and Melan-A, but weakly positive for S100. Based on these findings, definitive diagnosis of melanotic neuroectodermal tumor of infancy was established. Then, enucleation of the lesion was performed by careful curettage. After 2 year follow-up, no clinical or radiographical evidence of recurrence was verified. The present case highlights the importance of early diagnosis and therapeutic intervention at the appropriate time to achieve a favorable outcome for the patient.

title: Influence of growth hormone replacement on neurological and psychomotor development. Case report

description: ABSTRACT The height response to the use of growth hormone in short height cases has already been confirmed in the literature. The influence of the insulin-like growth factor 1 (GH-IGF1) axis components on development, function, regeneration, neuroprotection, cognition, and motor functions has been evaluated in experimental studies and in adults with central nervous system lesions. However, there is still little research on the clinical impact of hormone replacement on neurological and psychomotor development. This report presents the case of a patient with excellent weight-height recovery and, even more surprisingly, neurological and psychomotor development in response to use of growth hormone. The result strengthens the correlation between experimental and clinical findings related to cerebral plasticity response to growth hormone in children. A preterm male patient with multiple health problems during the neonatal and young infancy period, who for six years presented with a relevant deficit in growth, bone maturation, and neurological and psychomotor development. At six years of age, he had low stature (z-score −6.89), low growth rate, and low weight (z-score −7.91). He was incapable of sustaining his axial weight, had not developed fine motor skills or sphincter control, and presented with dysfunctional swallowing and language. Supplementary tests showed low IGF-11 levels, with no changes on the image of the hypothalamus-pituitary region, and bone age consistent with three-year-old children — for a chronological age of six years and one month. Growth hormone replacement therapy had a strong impact on the weight-height recovery as well as on the neurological and psychomotor development of this child.

title: X-linked spinal and bulbar muscular atrophy (Kennedy’s disease): the first case described in the Brazilian Amazon

description: ABSTRACT The X-linked spinal and bulbar muscular atrophy (Kennedy’s disease) is a rare X-linked, recessive, lower motor neuron disease, characterized by weakness, atrophy, and fasciculations of the appendicular and bulbar muscle. The disease is caused by an expansion of the CAG repetition in the androgen receptor gene. Patients with Kennedy’s disease have more than 39 CAG repetitions. We report a case of 57-year-old man, resident of Monte Dourado (PA, Brazil) who complained of brachiocrural paresis evolving for 3 years along with fasciculations and tremors of extremities. In addition, he also developed dysarthria, dysphagia, and sexual dysfunction. The patient clinical picture included gait impairment, global hyporeflexia, proximal muscle atrophy of upper limbs, deviation of the uvula to right during phonation and tongue atrophy with fasciculations. The patient reported that about 30 years ago he had undergone gynecomastia surgery. His electroneuromyography suggested spinal muscular atrophy, and nuclear magnetic resonance imaging showed tapering of the cervical and thoracic spinal cord. Patient’s creatine kinase level was elevated. In view of the findings, an exam was requested to investigate Kennedy’s disease. The exam identified 46 CAG repetitions in the androgen receptor gene, which confirmed the diagnostic suspicion. This was the first case of Kennedy’s disease diagnosed and described in the Brazilian Amazon. To our knowledge only other four papers were published on this disease in Brazilian patients. A brief review is also provided on etiopathogenic, clinical and diagnostic aspects.

title: Immunotherapy-induced pneumonitis: cases report

description: ABSTRACT Immunotherapy-induced pneumonitis is a rare complication with incidence estimated around 3%. This disease is difficult to diagnose and has great morbidity. For this reason, it became a challenge for oncologists and emergencists. We reviewed the case of five patients who used anti-PD1 (program cell death receptor antagonist 1) for antineoplastic treatment and developed treatment-induced pneumonitis. All patients had respiratory problems because of immunotherapy and presence of ground-glass radiologic change. Among all patients, only one had grade 5 pneumonitis, and delaying to begin corticosteroid therapy and worsening in clinical picture led to patient death. Other four patients with symptomatic grade 2 pneumonitis underwent corticosteroid therapy and had improvement in clinical and radiologic picture. Two patients were treated after an episode of pneumonitis, and no new pulmonary complications were observed until the end of this study. Immunotherapy-induced pneumonitis, although uncommon, can be potentially fatal. Medical team has the responsibility to pay attention for most common symptoms of the disease such as cough and dyspnea and conduct an early diagnosis and effective early treatment with corticosteroids.

title: Analysis of the muscle tissue of Wistar rats submitted to the sciatic nerve compression model and cryotherapy

description: ABSTRACT Objective: To evaluate the effects of right sciatic nerve compression and cryotherapy on muscle tissue. Methods: We used 42 male Wistar rats, subdivided in the following Groups Control, Injury 3, Injury 8 and Injury 15 submitted to nerve compression and euthanized in the 3rd, 8th and 15th day after surgery. The Cryotherapy Injury 3 was entailed treatment with cryotherapy by immersion of the animal in recipient for 20 minutes during 1 day, then animals were euthanized at the 3rd day after surgery, and the Cryotherapy Injury 8 and the Cryotherapy Injury 15 was treated for 6 days, and euthanized at the 8th and 15th day after surgery. Functional evaluation was performed by the grasping strength of the right pelvic limb. The right tibialis anterior muscles were evaluated for mass, smaller diameter and cross-sectional area. In the Cryotherapy Injury 8 and the Cryotherapy Injury 15 groups, the hydroxyproline was dosed in the right soles. Results: In the compression there was a significant difference in the Injury Groups compared with the Control Group (p&lt;0.05). In the smaller diameter, the compression in Control Group was higher than Injury 8 (p=0.0094), Injury 15 (p=0.002) and Cryotherapy Injury 15 (p&lt;0.001) groups. The comparison between groups with euthanasia in the same post-operative period, a significant difference (p=0.0363) was seen in day 8th after surgery, and this result in Cryotherapy Injury Group was greater than Injury Group. In the fiber area, Control Group was also higher than the Injury 8 (p=0.0018), the Injury 15 (p&lt;0.001) and the Cryotherapy Injury 15 (p&lt;0.001). In hydroxyproline, no significant difference was seen between groups. Conclusion: Nerve damage resulted in decreased muscle strength and trophism, the cryotherapy delayed hypotrophy, but this effect did not persist after cessation of treatment.

title: Urinary incontinence following subtotal and total hysterectomy: a systematic review

description: ABSTRACT Objective: To evaluate the best surgical approach for the female urinary incontinence. Methods: Systematic review conducted in MEDLINE® Cochrane, EMBASE and LILACS database up to September 1st, 2017. Articles were selected according to study type, type of intervention and outcomes. Articles were selected by more than one researcher based on title, abstract and full text. The SIGN checklist was used for bias assessment. Results: A total of 165 articles were retrieved from MEDLINE® . Twenty-five studies were elected for full text reading, and 11 of them were selected for the final text analysis. The heterogeneity between questionnaires used in different studies precluded a meta-analysis of results. Conclusion: This study yielded evidences supporting the hypothesis that total and subtotal hysterectomy have different impacts on urinary function of patients with benign uterine diseases. Articles revealed higher frequency of urinary incontinence following subtotal compared to total hysterectomy.

title: Cost-effectiveness analysis of abiraterone, docetaxel or placebo plus androgen deprivation therapy for hormone-sensitive advanced prostate cancer

description: ABSTRACT Objective To evaluate the cost-effectiveness of the addition of chemotherapy or abiraterone to androgen deprivation. Methods We developed an analytical model to determine the cost-effectiveness of the addition of docetaxel or abiraterone versus androgen deprivation therapy alone. Direct and indirect costs were included in the model. The effects were expressed in Quality-Adjusted Life Years adjusted for side effects. Results Compared to androgen deprivation therapy alone, the addition of chemotherapy and of abiraterone generated 0.492 and 0.999, respectively, in Quality-Adjusted Life Years. Abiraterone led to a Quality-Adjusted Life Years gain of 0.506 compared to docetaxel. The incremental costs per Quality-Adjusted Life Years were R$ 133.649,22 for docetaxel, R$ 330.828,70 for abiraterone and R$ 571.379,42 for abiraterone compared to docetaxel, respectively. Conclusion The addition of chemotherapy to androgen deprivation therapy is more cost-effective than the addition of abiraterone to androgen deprivation therapy. However, discounts on abiraterone cost might improve cost-effectiveness.

title: Resolubility of eye care in a secondary care center: a quantitative approach

description: ABSTRACT Objective To evaluate the resolubility of ophthalmologic care in an integrated health center. Methods This was a cross-sectional study including 816 patients who were attended from November 2013 to November of 2015. Data were collected from a medical consultation database and patients’ medical records. Results The majority of participants were women, non-diabetic, and had high school education. The main cause of referral for ophthalmologic evaluation was the consultation with a specialist, the waiting time for consultation was shorter for non-diabetic patients. Conclusion This Integrated health center presented, partial resolubility conditions to meet the ophthalmologic needs of users of the Brazilian Unified Health System. Eye care needs to be reorganized particularly by consider the priority cases of those at ophthalmological risk, and referrals should be done to the adequate care level and on time to guarantee resolubility.

title: Is virtual reality useful for pain management in patients who undergo medical procedures?

description: ABSTRACT Pain management is a complex medical issue, and many efforts have been done to develop new non-pharmacological therapies. Virtual reality is a technology apparatus that make an interaction between human and virtual environment through an hardware (usually a headset) linked to a computer or a mobile, by using a software. Additionally, this virtual setting can be adapted to any type of scenario. Thus, it is plausible that the software used should be personalized depending on patient’s experiences and expectations. The use of virtual reality as a medical tool for pain relief or decrease analgesics use by promoting a cognitive distraction is a low cost and promising instrument for pain management in patients who undergo medical procedures.
