What are the treatments for Human T-cell leukemia virus type 1 ?

No cure or treatment exists for human T-cell leukemia virus, type 1 (HTLV-1). Management is focused on early detection and preventing the spread of HTLV-1 to others. Screening blood doners, promoting safe sex and discouraging needle sharing can decrease the number of new infections. Mother-to-child transmission can be reduced by screening pregnant women so infected mothers can avoid breastfeeding.

Is the glutathione-related detoxification system increased in human breast cancer in correlation with clinical and histopathological features?

The breast tumours improved their redox status and detoxification capacities depending on various parameters of significance for cell proliferation and aggressiveness, which supports the involvement of the glutathione pathway in malignant cell resistance to oxidative stress and apoptosis.

What are the genetic changes related to adermatoglyphia ?

Adermatoglyphia is caused by mutations in the SMARCAD1 gene. This gene provides information for making two versions of the SMARCAD1 protein: a full-length version that is active (expressed) in multiple tissues and a shorter version that is expressed only in the skin. Studies suggest that the full-length SMARCAD1 protein regulates the activity of a wide variety of genes involved in maintaining the stability of cells' genetic information. Little is known about the function of the skin-specific version of the SMARCAD1 protein, but it appears to play a critical role in dermatoglyph formation. Dermatoglyphs develop before birth and remain the same throughout life. The activity of this protein is likely one of several factors that determine each person's unique fingerprint pattern. The SMARCAD1 gene mutations that cause adermatoglyphia affect only the skin-specific version of the SMARCAD1 protein. These mutations reduce the total amount of this protein available in skin cells. Although it is unclear how these genetic changes cause adermatoglyphia, researchers speculate that a shortage of the skin-specific version of the SMARCAD1 protein impairs signaling pathways needed for normal skin development and function, including the formation of dermatoglyphs.

What is (are) Psoriasis ?

Psoriasis is a chronic skin disease. Chronic means that it lasts a long time, often a lifetime. Psoriasis affects more than 5 million adults in the United States. It appears about equally in males and females. Psoriasis occurs when the skin cells grow too quickly. The body does not shed these excess cells and they build up on the surface of the skin, forming thick, scaly patches.

Is hilar location an independent prognostic factor for recurrence in T1 renal cell carcinoma after nephrectomy?

Hilar tumors show a higher recurrence rate than nonhilar counterparts in T1 RCC. In T1a hilar tumors, PN demonstrated poorer RFS than RN. Potential intrinsic renal anatomical or lymphovascular structural differences as well as differences in cancer characteristics need further investigations.

Does hyperglycemia increase the risk of death in extremely preterm baboons?

HG is common in preterm baboons and is not associated with short-term morbidity. Severe HG occurring in the first week of life is associated with early death in preterm baboons.

Do different gonadotropin and leuprorelin ovulation induction regimens markedly affect follicular fluid hormone levels and folliculogenesis?

Long GnRH-a regimens improved follicle yield and the endocrine milieu in spite of comparable exogenous gonadotropin dose and lower serum FSH and thus appear to be preferable in assisted reproduction. Reduced folliculogenesis found in flare-up GnRH-a regimens could be mediated by the atretic effects of high intraovarian androgens. Efficacy of purified FSH and hMG was comparable.

What are the treatments for Tay-Sachs disease ?

Although several attempts have been made at purified enzyme replacement therapy for children with Tay-Sachs disease, none has been successful. Cellular infusions and even bone marrow transplantation have been attempted with no evidence of benefit. Because no specific treatment is available for Tay-Sachs disease, treatment is directed at the symptoms and major associated conditions. Treatment is supportive and aimed at providing adequate nutrition and hydration. The airway must be protected. Seizures can be controlled initially with conventional anticonvulsant medications such as benzodiazepines, phenytoins, and/or barbiturates, but the progressive nature of the disease may require alteration of dosage or medication. Infectious diseases should be managed. In advanced disease, good bowel movement should be maintained and severe constipation should be avoided. Good hydration, food additives, stool softeners, laxatives, and other measures should be employed to avoid severe constipation.

Does anxiety during early pregnancy predict postpartum weight retention in obese mothers?

PPWR in obese mothers is associated with psychological discomfort during early pregnancy. Besides the importance of adequate prenatal weight management, focused psychological support should be an important cue to action in obese women, to prevent maternal obesity on the long run.

Does butein provide neuroprotective and anti-neuroinflammatory effects through Nrf2/ARE-dependent haem oxygenase 1 expression by activating the PI3K/Akt pathway?

Our results indicate that butein effectively prevents glutamate-induced oxidative damage and LPS-induced activation and that the induction of HO1 by butein through the PI3K/Akt pathway and Nrf2 activation appears to play a pivotal role in its effects on neuronal cells. Our results provide evidence for the neuroprotective properties of butein.

Is autosomal recessive congenital cataract in consanguineous Pakistani families associated with mutations in GALK1?

Here, we report pathogenic mutations in GALK1 that are responsible for autosomal recessive congenital cataracts in consanguineous Pakistani families.

Do you have information about Ultrasound

Summary : Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus. Unlike x-rays, ultrasound does not expose you to radiation. During an ultrasound test, you lie on a table. A special technician or doctor moves a device called a transducer over part of your body. The transducer sends out sound waves, which bounce off the tissues inside your body. The transducer also captures the waves that bounce back. The ultrasound machine creates images from the sound waves.

What causes Simple Kidney Cysts ?

The cause of simple kidney cysts is not fully understood. Obstruction of tubulestiny structures within the kidneys that collect urineor deficiency of blood supply to the kidneys may play a role. Diverticulasacs that form on the tubulesmay detach and become simple kidney cysts. The role of genetic factors in the development of simple kidney cysts has not been studied.

Does surgical stress induce brain-derived neurotrophic factor reduction and postoperative cognitive dysfunction via glucocorticoid receptor phosphorylation in aged mice?

These results presented a mechanism that surgical stress-induced GR phosphorylation contributes to POCD in aged individuals. Inhibition of GR activation and phosphorylation might be a potential treatment target of POCD.

Is quality of life more impaired in patients seeking medical care for food allergy?

Patients who seek medical care for their FA have a more impaired HRQL and perceive their FA as more severe. Food avoidance and issues related to the EI of FA are key areas of intervention aimed at improving HRQL in patients with FA.

Are patient identification errors common in a simulated setting?

Wide variation exists among health care workers verifying patient identity before performing everyday tasks. Education, process changes, and technology are needed to improve the frequency and accuracy of patient identification.

Is hepatitis C infection very rarely treated among hemodialysis patients?

HD patients with hepatitis C infection very rarely receive antiviral therapy. Increased intervention might prolong survival for some patients and in particular might improve the prospects for those awaiting renal transplantation.

What is (are) Rickets ?

Rickets is a condition that causes children to have soft, weak bones. It usually occurs when children do not get enough vitamin D, which helps growing bones absorb important nutrients. Vitamin D comes from sunlight and food. Skin produces vitamin D in response to the sun's rays. Some foods also contain vitamin D, including fortified dairy products and cereals, and some kinds of fish.

Does dasatinib induce autophagic cell death in human ovarian cancer?

Dasatinib induces autophagic cell death in ovarian cancer that partially depends on beclin 1, AKT, and Bcl-2. These results may have implications for clinical use of dasatinib.

What are the treatments for Cornelia de Lange syndrome ?

Because Cornelia de Lange syndrome (CdLS) affects many different systems of the body, medical management is often provided by a team of doctors and other healthcare professionals. Treatment for this condition varies based on the signs and symptoms present in each person. For example, many people affected by CdLS have poor growth after birth and may require supplemental formulas and/or gastrostomy tube placement to meet nutritional needs. Ongoing physical, occupational, and speech therapies are often recommended to optimize developmental potential. Surgery may be necessary to treat skeletal abnormalities, gastrointestinal problems, congenital heart defects and other health problems. Medications may be prescribed to prevent or control seizures. The CdLS foundation's Web site offers more specific information about the treatment and management of CdLS. Please click on the link to access this resource.

What are the genetic changes related to familial erythrocytosis ?

Familial erythrocytosis can result from mutations in the EPOR, VHL, EGLN1, or EPAS1 gene. Researchers define four types of familial erythrocytosis, ECYT1 through ECYT4, based on which of these genes is altered. The EPOR gene provides instructions for making a protein known as the erythropoietin receptor, which is found on the surface of certain blood-forming cells in the bone marrow. Erythropoietin is a hormone that directs the production of new red blood cells. Erythropoietin fits into the receptor like a key into a lock, triggering signaling pathways that lead to the formation of red blood cells. Mutations in the EPOR gene cause the erythropoietin receptor to be turned on for an abnormally long time after attaching to erythropoietin. The overactive receptor signals the production of red blood cells even when they are not needed, which results in an excess of these cells in the bloodstream. When familial erythrocytosis is caused by mutations in the EPOR gene, it is known as ECYT1. The proteins produced from the VHL, EGLN1, and EPAS1 genes are also involved in red blood cell production; they each play a role in regulating erythropoietin. The protein produced from the EPAS1 gene is one component of a protein complex called hypoxia-inducible factor (HIF). When oxygen levels are lower than normal (hypoxia), HIF activates genes that help the body adapt, including the gene that provides instructions for making erythropoietin. Erythropoietin stimulates the production of more red blood cells to carry oxygen to organs and tissues. The proteins produced from the VHL and EGLN1 genes indirectly regulate erythropoietin by controlling the amount of available HIF. Mutations in any of these three genes can disrupt the regulation of red blood cell formation, leading to an overproduction of these cells. When familial erythrocytosis results from VHL gene mutations it is known as ECYT2; when the condition is caused by EGLN1 gene mutations it is called ECYT3; and when the condition results from EPAS1 gene mutations it is known as ECYT4. Researchers have also described non-familial (acquired) forms of erythrocytosis. Causes of acquired erythrocytosis include long-term exposure to high altitude, chronic lung or heart disease, episodes in which breathing slows or stops for short periods during sleep (sleep apnea), and certain types of tumors. Another form of acquired erythrocytosis, called polycythemia vera, results from somatic (non-inherited) mutations in other genes involved in red blood cell production. In some cases, the cause of erythrocytosis is unknown.

What is (are) Self-harm ?

Self-harm refers to a person's harming their own body on purpose. About 1 in 100 people hurts himself or herself in this way. More females hurt themselves than males. A person who self-harms usually does not mean to kill himself or herself. But they are at higher risk of attempting suicide if they do not get help. Self-harm tends to begin in teen or early adult years. Some people may engage in self-harm a few times and then stop. Others engage in it more often and have trouble stopping. Examples of self-harm include - Cutting yourself (such as using a razor blade, knife, or other sharp object to cut the skin) - Punching yourself or punching things (like a wall) - Burning yourself with cigarettes, matches, or candles - Pulling out your hair - Poking objects through body openings - Breaking your bones or bruising yourself Many people cut themselves because it gives them a sense of relief. Some people use cutting as a means to cope with a problem. Some teens say that when they hurt themselves, they are trying to stop feeling lonely, angry, or hopeless. It is possible to overcome the urge to hurt yourself. There are other ways to find relief and cope with your emotions. Counseling may help. Dept. of Health and Human Services, Office on Women's Health

What are the genetic changes related to frontonasal dysplasia ?

Mutations in the ALX3 gene cause frontonasal dysplasia type 1, ALX4 gene mutations cause type 2, and ALX1 gene mutations cause type 3. These genes provide instructions for making proteins that are necessary for normal development, particularly of the head and face, before birth. The proteins produced from the ALX3, ALX4, and ALX1 genes are transcription factors, which means they attach (bind) to DNA and control the activity of certain genes. Specifically, the proteins control the activity of genes that regulate cell growth and division (proliferation) and movement (migration), ensuring that cells grow and stop growing at specific times and that they are positioned correctly during development. The ALX3 and ALX4 proteins are primarily involved in the development of the nose and surrounding tissues, while the ALX1 protein is involved in development of the eyes, nose, and mouth. ALX3, ALX4, or ALX1 gene mutations reduce or eliminate function of the respective protein. As a result, the regulation of cell organization during development of the head and face is disrupted, particularly affecting the middle of the face. Abnormal development of the nose, philtrum, and upper lip leads to the facial clefts that characterize this disorder. This abnormal development also interferes with the proper formation of the skull and other facial structures, leading to anterior cranium bifidum occultum, hypertelorism, and other features of frontonasal dysplasia.

The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Is sickle cell disease inherited ?

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Does truncation mutation in HRG4 ( UNC119 ) lead to mitochondrial ANT-1-mediated photoreceptor synaptic and retinal degeneration by apoptosis?

The results support a novel mechanism of retinal degeneration in which preapoptotic degeneration starts in the photoreceptor synapse because of a deficiency in ANT-1 and spreads to the secondary neuron transsynaptically, followed by apoptosis and degeneration in the cell body of the photoreceptor.

Is intraoperative blood loss a predictor of prognosis for pancreatic cancer?

Minimizing IBL is very important; however, the present study found that positive lymph node metastasis and R-status were stronger independent prognostic factors for pancreatic cancer.

Do tuberculosis risk-associated single nucleotide polymorphisms show association with leprosy in Chinese population?

Although leprosy and TB have a number of similar characteristics, no shared susceptibility loci were found in the Chinese Han population. Thus, this study demonstrated that the genetic basis of the pathogenesis of the two diseases may vary greatly.

Do serum cholesterol and statin use predict virological response to peginterferon and ribavirin therapy?

Is verapamil-sustained release-based treatment strategy equivalent to atenolol-based treatment strategy at reducing cardiovascular events in patients with prior myocardial infarction : an INternational VErapamil SR-Trandolapril ( INVEST ) substudy?

In hypertensive patients with prior MI, a verapamil-SR-based strategy was equivalent to a beta-blocker-based strategy for blood pressure control and prevention of cardiovascular events, with greater subjective feeling of well-being and a trend toward lower incidence of angina pectoris and stroke in the verapamil-SR-based group.

Is transcranial Doppler-directed Dextran-40 therapy a cost-effective method of preventing carotid thrombosis after carotid endarterectomy?

postoperative TCD monitoring is a clinically effective and also cost-effective method of reducing the stroke rate associated with CEA. For units performing more than 50 CEAs per year who experience occasional postoperative carotid thrombosis, its introduction should be considered.

Does communication of prenatal screening and diagnosis result to primary-care health professionals?

The frequent absence of means of effective communication between primary and secondary care about diagnosed abnormalities, and health professionals' uncertainties about their role has implications for the quality of care given to women who receive positive results after prenatal screening or diagnosis. There is a need for standards to be established concerning the communication of information to the health professionals responsible for the community-based care of pregnant women after a positive test result.

What is (are) Diabetes and Pregnancy ?

Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. When you are pregnant, high blood sugar levels are not good for your baby. About seven out of every 100 pregnant women in the United States get gestational diabetes. Gestational diabetes is diabetes that happens for the first time when a woman is pregnant. Most of the time, it goes away after you have your baby. But it does increase your risk for developing type 2 diabetes later on. Your child is also at risk for obesity and type 2 diabetes. Most women get a test to check for diabetes during their second trimester of pregnancy. Women at higher risk may get a test earlier. If you already have diabetes, the best time to control your blood sugar is before you get pregnant. High blood sugar levels can be harmful to your baby during the first weeks of pregnancy - even before you know you are pregnant. To keep you and your baby healthy, it is important to keep your blood sugar as close to normal as possible before and during pregnancy. Either type of diabetes during pregnancy increases the chances of problems for you and your baby. To help lower the chances talk to your health care team about - A meal plan for your pregnancy - A safe exercise plan - How often to test your blood sugar - Taking your medicine as prescribed. Your medicine plan may need to change during pregnancy. NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Is Congenital myasthenic syndrome inherited ?

Almost all types of CMS are inherited in an autosomal recessive manner. In order to have the autosomal recessive form of CMS, both parents of an affected individual must be carriers of the disease causing mutation. If a person has CMS, but their partner is not a carrier of a CMS mutation, then their children will be carriers but will not have CMS. If one person has CMS and one person is a carrier of CMS, each child has a 50% chance of either being a carrier of CMS or having the disorder. Only one form of CMS (slow-channel syndrome congenital myasthenic syndrome) has been shown to be inherited in an autosomal dominant manner. This means that if one parent has slow-channel syndrome congenital myasthenic syndrome then all of their children have a 50% chance of inheriting the disorder as well. It is important to discuss this information with your health care provider, such as a genetic counselor, to accurately determine a person's risk for passing on this disorder.

What is (are) Duane-radial ray syndrome ?

Duane-radial ray syndrome is a disorder that affects the eyes and causes abnormalities of bones in the arms and hands. This condition is characterized by a particular problem with eye movement called Duane anomaly (also known as Duane syndrome). This abnormality results from the improper development of certain nerves that control eye movement. Duane anomaly limits outward eye movement (toward the ear), and in some cases may limit inward eye movement (toward the nose). Also, as the eye moves inward, the eye opening becomes narrower and the eyeball may pull back (retract) into its socket. Bone abnormalities in the hands include malformed or absent thumbs, an extra thumb, or a long thumb that looks like a finger. Partial or complete absence of bones in the forearm is also common. Together, these hand and arm abnormalities are known as radial ray malformations. People with the combination of Duane anomaly and radial ray malformations may have a variety of other signs and symptoms. These features include unusually shaped ears, hearing loss, heart and kidney defects, a distinctive facial appearance, an inward- and upward-turning foot (clubfoot), and fused spinal bones (vertebrae). The varied signs and symptoms of Duane-radial ray syndrome often overlap with features of other disorders. For example, acro-renal-ocular syndrome is characterized by Duane anomaly and other eye abnormalities, radial ray malformations, and kidney defects. Both conditions are caused by mutations in the same gene. Based on these similarities, researchers suspect that Duane-radial ray syndrome and acro-renal-ocular syndrome are part of an overlapping set of syndromes with many possible signs and symptoms. The features of Duane-radial ray syndrome are also similar to those of a condition called Holt-Oram syndrome; however, these two disorders are caused by mutations in different genes.

Is increased preference of surface ablation over laser in situ keratomileusis between 2008-2011 correlated to risk of ecatasia?

Our results indicate that with time, surface ablation tended to be performed more often than LASIK for the correction of myopia in our cohort. Increased awareness of risk factors and preoperative risk assessment tools, such as the ERFSS, have shifted the current practice of refractive surgery from LASIK towards surface ablation despite the former's advantages, especially in cases in which the risk for ectasia is more than minimal (risk score 2 and higher).

What are the symptoms of Medullary Sponge Kidney ?

Many people with medullary sponge kidney have no symptoms. The first sign that a person has medullary sponge kidney is usually a UTI or a kidney stone. UTIs and kidney stones share many of the same signs and symptoms: - burning or painful urination - pain in the back, lower abdomen, or groin - cloudy, dark, or bloody urine - foul-smelling urine - fever and chills - vomiting People who experience these symptoms should see or call a health care provider as soon as possible.

What is (are) Crouzon syndrome ?

Crouzon syndrome is a genetic disorder characterized by the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face. Many features of Crouzon syndrome result from the premature fusion of the skull bones. Abnormal growth of these bones leads to wide-set, bulging eyes and vision problems caused by shallow eye sockets; eyes that do not point in the same direction (strabismus); a beaked nose; and an underdeveloped upper jaw. In addition, people with Crouzon syndrome may have dental problems and hearing loss, which is sometimes accompanied by narrow ear canals. A few people with Crouzon syndrome have an opening in the lip and the roof of the mouth (cleft lip and palate). The severity of these signs and symptoms varies among affected people. People with Crouzon syndrome are usually of normal intelligence.

What is (are) Hemolytic uremic syndrome, atypical, childhood ?

Hemolytic uremic syndrome, atypical, childhood is a disease that causes abnormal blood clots to form in small blood vessels in the kidneys. These clots can cause serious medical problems if they restrict or block blood flow, including hemolytic anemia, thrombocytopenia, and kidney failure. It is often caused by a combination of environmental and genetic factors. Genetic factors involve genes that code for proteins that help control the complement system (part of your bodys immune system). Environmental factors include viral or bacterial infections, certain medications (such as anticancer drugs), chronic diseases, cancers, and organ transplantation. Most cases are sporadic. Less than 20 percent of all cases have been reported to run in families. When the disorder is familial, it can have an autosomal dominant or an autosomal recessive pattern of inheritance. Atypical hemolytic-uremic syndrome differs from a more common condition called typical hemolytic-uremic syndrome. The two disorders have different causes and symptoms.

Is the classic form of granular corneal dystrophy associated with R555W mutation in the BIGH3 gene rare in Japanese patients?

These results, together with our previous findings, show that the classic form of granular corneal dystrophy associated with the R555W mutation is rare in Japanese patients, whereas granular corneal dystrophy accompanied by amyloid deposits and associated with the R124H mutation, Avellino corneal dystrophy, is more common. Direct examination may be insufficient in the proper diagnosis of corneal dystrophy, and BIGH3 mutation analysis may be required.

What are the symptoms of Frank Ter Haar syndrome ?

The Human Phenotype Ontology provides the following list of signs and symptoms for Frank Ter Haar syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Motor delay 5% Abnormality of cardiovascular system morphology - Anterior concavity of thoracic vertebrae - Bowing of the long bones - Broad clavicles - Broad nasal tip - Buphthalmos - Coarse facial features - Cortical irregularity - Delayed cranial suture closure - Dental malocclusion - Flared metaphysis - Flat occiput - Full cheeks - Gingival overgrowth - Growth delay - High palate - Hip dysplasia - Hypertelorism - Large eyes - Low-set ears - Osteopenia - Osteoporosis - Pectus excavatum - Prominent coccyx - Prominent forehead - Proptosis - Protruding ear - Short long bone - Short phalanx of finger - Talipes equinovarus - Wide anterior fontanel - Wide mouth - Wormian bones - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

What is (are) Twin twin transfusion syndrome ?

Twin-to-twin transfusion syndrome is a rare condition that occurs when blood moves from one identical twin (the donor twin) to the other (the recipient twin) while in the womb. The donor twin may be born smaller, with paleness, anemia, and dehydration. The recipient twin may be born larger, with redness, too much blood, and increased blood pressure, resulting in an increased risk for heart failure. Treatment may require repeated amniocentesis during pregnancy. Fetal laser surgery may be done to interrupt the flow of blood from one twin to the other. After birth, treatment depends on the infant's specific symptoms. The donor twin may need a blood transfusion to treat anemia. The recipient twin may need to have the volume of body fluid reduced. This may involve an exchange transfusion. Medications may be given to treat heart failure in the recipient twin.

What is (are) Pachydermoperiostosis ?

Pachydermoperiostosis is a rare disorder characterized by clubbing of the fingers and toes; thickening of the skin of the face (pachyderma); excessive sweating (hyperhidrosis); and new bone formation associated with joint pain. Other features may include congenital heart disease and delayed closure of fontanelles. This condition typically appears during childhood or adolescence, often around the time of puberty, and progresses slowly for about ten years. Both autosomal dominant and autosomal recessive inheritance has been reported. Mutations in the HPGD gene have been found in those with the autosomal recessive form of this condition.

Is neutrophil gelatinase-associated lipocalin a sensitive biomarker for the early diagnosis of acute rejection after living-donor kidney transplantation?

Urine NGAL level was found to be the most sensitive biomarker of acute kidney allograft dysfunction after living-donor kidney transplantation.

Is hDL redox activity increased in HIV-infected men in association with macrophage activation and non-calcified coronary atherosclerotic plaque?

These data demonstrate increased HRA among HIV-infected subjects versus matched non-HIV subjects with comparable HDL levels. In HIV-infected subjects, HRA relates to macrophage activation and to non-calcified coronary atherosclerotic plaque, which may be rupture-prone. Further studies are needed in HIV-infected patients to elucidate the interplay between immune activation, HDL function and CVD risk.

Does comprehensive transcriptional profiling of NaCl-stressed Arabidopsis roots reveal novel classes of responsive genes?

Microarray profiling of NaCl-treated Arabidopsis roots revealed dynamic changes in transcript abundance for at least 20% of the genome, including hundreds of transcription factors, kinases/phosphatases, hormone-related genes, and effectors of homeostasis, all of which highlight the complexity of this stress response. Our identification of these transcriptional responses, and groups of evolutionarily related genes with either similar or divergent transcriptional responses to stress, will facilitate mapping of regulatory networks and extend our ability to improve salt tolerance in plants.

What is (are) Childhood Central Nervous System Germ Cell Tumors ?

Key Points - Childhood central nervous system (CNS) germ cell tumors form from germ cells. - There are different types of childhood CNS germ cell tumors. - Germinomas - Nongerminomas - The cause of most childhood CNS germ cell tumors is not known. - Signs and symptoms of childhood CNS germ cell tumors include unusual thirst, frequent urination, early puberty, or vision changes. - Imaging studies and tests are used to detect (find) and diagnose childhood CNS germ cell tumors. - A biopsy may be done to be sure of the diagnosis of CNS germ cell tumor. - Certain factors affect prognosis (chance of recovery). Childhood central nervous system (CNS) germ cell tumors form from germ cells. Germ cells are a type of cell that form as a fetus (unborn baby) develops. These cells later become sperm in the testicles or eggs in the ovaries. Sometimes while the fetus is forming, germ cells travel to other parts of the body and grow into germ cell tumors. Germ cells tumors that form in the brain or spinal cord are called CNS germ cell tumors. The most common places for one or more central nervous system (CNS) germ cell tumors to form is near the pineal gland and in an area of the brain that includes the pituitary gland and the tissue just above it. Sometimes germ cell tumors may form in other areas of the brain. This summary is about germ cell tumors that start in the central nervous system (brain and spinal cord). Germ cell tumors may also form in other parts of the body. See the PDQ summary on Childhood Extracranial Germ Cell Tumors Treatment for information on germ cell tumors that are extracranial (outside the brain). CNS germ cell tumors usually occur in children, but may occur in adults. Treatment for children may be different than treatment for adults. See the following PDQ summaries for information about treatment for adults: - Adult Central Nervous System Tumors Treatment - Extragonadal Germ Cell Tumors Treatment For information about other types of childhood brain and spinal cord tumors, see the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview. There are different types of childhood CNS germ cell tumors. There are different types of CNS germ cell tumors. The type of CNS germ cell tumor depends on what the cells look like under a microscope. This summary is about the treatment of the following types of CNS germ cell tumors: Germinomas Germinomas are the most common type of CNS germ cell tumor and have a good prognosis. Nongerminomas Some nongerminomas make hormones. CNS teratomas are a type of nongerminoma that does not make hormones. They may have different kinds of tissue in them, such as hair, muscle, and bone. Teratomas are described as mature or immature, based on how normal the cells look under a microscope. Sometimes teratomas are a mix of mature and immature cells. Other types of nongerminomas include the following: - Choriocarcinomas make the hormone beta-human chorionic gonadotropin (-hCG). - Embryonal carcinomas do not make hormones. - Yolk sac tumors make the hormone alpha-fetoprotein (AFP). - Mixed germ cell tumors are made of more than one kind of germ cell.

Does intracytoplasmic sperm injection increase embryo fragmentation without affecting clinical outcome?

These data suggest that ICSI, irrespective of semen parameters, may increase embryo fragmentation and produce fewer nonfragmented grade I embryos while maintaining implantation and pregnancy rates similar to conventional IVF.

What is (are) Mowat-Wilson syndrome ?

Mowat-Wilson syndrome (MWS) is a rare genetic disorder that affects many systems of the body. The main features include moderate to severe intellectual disability, distinctive facial features, and epilepsy. Other features may include Hirschsprung disease; heart (cardiac) defects; kidney (renal) abnormalities; genital abnormalities; eye abnormalities; and short stature. It is caused by a mutation or deletion in the ZEB2 gene, which usually occurs for the first time (sporadically) in affected people. Treatment typically focuses on the specific symptoms in each person.

Is elevated immune monitoring as measured by increased adenosine triphosphate production in activated lymphocytes associated with accelerated development of cardiac allograft vasculopathy after cardiac transplantation?

Elevated peak IM, as measured by increased ATP production, in activated lymphocytes is associated with decreased freedom from angiographic CAV.

What is (are) Speech and Language Problems in Children ?

Children vary in their development of speech and language skills. Health professionals have milestones for what's normal. These milestones help determine if a child is on track or if he or she may need extra help. For example, a child usually has one or two words like "Hi," "dog," "Dada," or "Mama" by her first birthday. Sometimes a delay may be caused by hearing loss, while other times it may be due to a speech or language disorder. Language disorders can mean that the child has trouble understanding what others say or difficulty sharing her thoughts. Children who have trouble producing speech sounds correctly or who hesitate or stutter when talking may have a speech disorder. If your child's speech or language appears to be delayed, talk to your child's doctor. NIH: National Institute on Deafness and Other Communication Disorders

Does expression of p120-catenin isoforms correlate with genomic and transcriptional phenotype of breast cancer cell lines?

We demonstrate that mammary tumour cells exhibit a characteristic p120-catenin isoform expression profile, depending from their specific genomic and transcriptional properties. These particular expression patterns, combined with other regulatory proteins and in a specific cellular context, may explain how p120-catenin can either contribute to strength intercellular adhesions or instead to promote cell motility.

What is (are) Age-related Macular Degeneration ?

Dry AMD occurs when the light-sensitive cells in the macula slowly break down, gradually blurring central vision in the affected eye. As dry AMD gets worse, you may see a blurred spot in the center of your vision. Over time, as less of the macula functions, central vision in the affected eye can be lost. If you have vision loss from dry AMD in one eye only, you may not notice any changes in your overall vision. With the other eye seeing clearly, you can still drive, read, and see fine details. You may notice changes in your vision only if AMD affects both eyes. If you experience blurry vision, see an eye care professional for a comprehensive dilated eye exam.

Does zinc deficiency aggravate abnormal glucose metabolism in thalassemia major patients?

These data support the assumption that zinc deficiency might lead to an exacerbation of the inability of the pancreas to secrete sufficient amounts of insulin in response to glucose stimulation in beta-thalassemia patients. We suggest that serum zinc levels be routinely monitored in these patients as it might provide useful complementaly information regarding glucose metabolism.

Is Retinoblastoma inherited ?

Retinoblastoma occurs in heritable and nonheritable forms. A child is thought to have the heritable form of retinoblastoma when one of the following is true: - There is a family history of retinoblastoma. - There is a certain mutation (change) in the RB1 gene. The mutation in the RB1 gene may be passed from the parent to the child or it may occur in the egg or sperm before conception or soon after conception. - There is more than one tumor in the eye or there is a tumor in both eyes. - There is a tumor in one eye and the child is younger than 1 year. After heritable retinoblastoma has been diagnosed and treated, new tumors may continue to form for a few years. Regular eye exams to check for new tumors are usually done every 2 to 4 months for at least 28 months. Nonheritable retinoblastoma is retinoblastoma that is not the heritable form. Most cases of retinoblastoma are the nonheritable form. Treatment for both forms of retinoblastoma should include genetic counseling. Parents should receive genetic counseling (a discussion with a trained professional about the risk of genetic diseases) to discuss genetic testing to check for a mutation (change) in the RB1 gene. Genetic counseling also includes a discussion of the risk of retinoblastoma for the child and the child's brothers or sisters. Children with a family history of retinoblastoma should have eye exams to check for retinoblastoma. A child with a family history of retinoblastoma should have regular eye exams beginning early in life to check for retinoblastoma, unless it is known that the child does not have the RB1 gene change. Early diagnosis of retinoblastoma may mean the child will need less intense treatment. Brothers or sisters of a child with retinoblastoma should have regular eye exams by an ophthalmologist until age 3 to 5 years, unless it is known that the brother or sister does not have the RB1 gene change. A child who has heritable retinoblastoma has an increased risk of trilateral retinoblastoma and other cancers. A child with heritable retinoblastoma has an increased risk of a pineal tumor in the brain. When retinoblastoma and a brain tumor occur at the same time, it is called trilateral retinoblastoma. The brain tumor is usually diagnosed between 20 and 36 months of age. Regular screening using MRI (magnetic resonance imaging) may be done for a child thought to have heritable retinoblastoma or for a child with retinoblastoma in one eye and a family history of the disease. CT (computerized tomography) scans are usually not used for routine screening in order to avoid exposing the child to ionizing radiation. Heritable retinoblastoma also increases the child's risk of other types of cancer such as lung cancer, bladder cancer, or melanoma in later years. Regular follow-up exams are important.

Is the catechol O-methyltransferase Val158Met polymorphism associated with broad-based cognitive functioning in schizophrenia?

Based on the results in our sample, the catechol O-methyltransferase Val158Met polymorphism is not associated with broad-based cognitive functioning in schizophrenia.

Does pET imaging of cortical 11C-nicotine binding correlate with the cognitive function of attention in Alzheimer 's disease?

Cortical nicotinic receptors in vivo in mild AD patients are robustly associated with the cognitive function of attention.

Are melanoma metastases in regional lymph nodes accurately detected by proton magnetic resonance spectroscopy of fine-needle aspirate biopsy samples?

Proton MRS of FNAB samples may provide a robust and accurate diagnosis of metastatic disease in the regional lymph nodes of melanoma patients. These data indicate the potential for SN staging of melanoma without surgical biopsy and histopathological evaluation.

What is (are) Wyburn Mason's syndrome ?

Wyburn Mason's syndrome is a condition in which blood vessels do not form correctly in both the retina of one eye and a part of the brain. These malformed blood vessels are called arteriovenous malformations (AVM). Wyburn Mason's syndrome is present from birth (congenital) and the cause is unknown. Individuals with this condition may have additional AVMs in other parts of the body, particularly the face. The symptoms of this condition are quite variable and depend on the size, location, and shape of the AVMs. Affected individuals may have no symptoms or may experience headaches, problems with vision, seizures, or partial paralysis (hemiparesis). Treatment usually consists of periodic visits to the doctor to see if the AVMs are changing over time.

What causes Lipodermatosclerosis ?

The exact cause of lipodermatosclerosis is unknown; however, it may be related to certain vein abnormalities and/or obesity. Lipodermatosclerosis often occurs in people with venous insufficiency. Approximately two thirds of affected people are obese.

Is pIVKA-II a useful tumor marker for recurrent hepatocellular carcinoma after surgical resection?

Our data suggest that PIVKA-II is a useful tumor marker for HCC, complementary to AFP. Serial measurements of both markers after resection might be helpful for early diagnosis of tumor recurrence.

What is (are) Levator syndrome ?

Levator syndrome is characterized by sporadic pain in the rectum caused by spasm of a muscle near the anus (the levator ani muscle). The muscle spasm causes pain that typically is not related to defecation. The pain usually lasts less than 20 minutes. Pain may be brief and intense or a vague ache high in the rectum. It may occur spontaneously or with sitting and can waken a person from sleep. The pain may feel as if it would be relieved by the passage of gas or a bowel movement. In severe cases, the pain can persist for many hours and can recur frequently. A person may have undergone various unsuccessful rectal operations to relieve these symptoms.

What is (are) Adult Acute Lymphoblastic Leukemia ?

Key Points - Adult acute lymphoblastic leukemia (ALL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). - Leukemia may affect red blood cells, white blood cells, and platelets. - Previous chemotherapy and exposure to radiation may increase the risk of developing ALL. - Signs and symptoms of adult ALL include fever, feeling tired, and easy bruising or bleeding. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose adult ALL. - Certain factors affect prognosis (chance of recovery) and treatment options. Adult acute lymphoblastic leukemia (ALL) is a type of cancer in which the bone marrow makes too many lymphocytes (a type of white blood cell). Adult acute lymphoblastic leukemia (ALL; also called acute lymphocytic leukemia) is a cancer of the blood and bone marrow. This type of cancer usually gets worse quickly if it is not treated. Leukemia may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - Platelets that form blood clots to stop bleeding. - Granulocytes (white blood cells) that fight infection and disease. A lymphoid stem cell becomes a lymphoblast cell and then one of three types of lymphocytes (white blood cells): - B lymphocytes that make antibodies to help fight infection. - T lymphocytes that help B lymphocytes make the antibodies that help fight infection. - Natural killer cells that attack cancer cells and viruses. In ALL, too many stem cells become lymphoblasts, B lymphocytes, or T lymphocytes. These cells are also called leukemia cells. These leukemia cells are not able to fight infection very well. Also, as the number of leukemia cells increases in the blood and bone marrow, there is less room for healthy white blood cells, red blood cells, and platelets. This may cause infection, anemia, and easy bleeding. The cancer can also spread to the central nervous system (brain and spinal cord). This summary is about adult acute lymphoblastic leukemia. See the following PDQ summaries for information about other types of leukemia: - Childhood Acute Lymphoblastic Leukemia Treatment. - Adult Acute Myeloid Leukemia Treatment. - Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment. - Chronic Lymphocytic Leukemia Treatment. - Chronic Myelogenous Leukemia Treatment. - Hairy Cell Leukemia Treatment.

Does intraluminal thyrotropin-releasing hormone affect gastric somatostatin and acid secretion through its specific receptor in rats?

These findings suggest that intraluminal TRH affects somatostatin and acid secretion in a paracrine manner via its specific receptor in the rat stomach.

Does urinary oxalate excretion increase in home parenteral nutrition patients on a higher intravenous ascorbic acid dose?

In therapeutically used doses, IV vitamin C increases urinary oxalate excretion, potentially predisposing susceptible individuals to nephrolithiasis. This factor should be considered in patients receiving home TPN.

What are the stages of Neuroblastoma ?

Key Points - After neuroblastoma has been diagnosed, tests are done to find out if cancer has spread from where it started to other parts of the body. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - The following stages are used for neuroblastoma: - Stage 1 - Stage 2 - Stage 3 - Stage 4 - Treatment of neuroblastoma is based on risk groups. After neuroblastoma has been diagnosed, tests are done to find out if cancer has spread from where it started to other parts of the body. The process used to find out the extent or spread of cancer is called staging. The information gathered from the staging process helps determine the stage of the disease. For neuroblastoma, the stage of disease affects whether the cancer is low risk, intermediate risk, or high risk. It also affects the treatment plan. The results of some tests and procedures used to diagnose neuroblastoma may be used for staging. See the General Information section for a description of these tests and procedures. The following tests and procedures also may be used to determine the stage: - Lymph node biopsy : The removal of all or part of a lymph node. A pathologist views the tissue under a microscope to look for cancer cells. One of the following types of biopsies may be done: - Excisional biopsy : The removal of an entire lymph node. - Incisional biopsy : The removal of part of a lymph node. - Core biopsy : The removal of tissue from a lymph node using a wide needle. - Fine-needle aspiration (FNA) biopsy : The removal of tissue or fluid from a lymph node using a thin needle. - X-ray of the bone: An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. There are three ways that cancer spreads in the body. Cancer can spread through tissue, the lymph system, and the blood: - Tissue. The cancer spreads from where it began by growing into nearby areas. - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body. - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body. Cancer may spread from where it began to other parts of the body. When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood. - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body. - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if neuroblastoma spreads to the liver, the cancer cells in the liver are actually neuroblastoma cells. The disease is metastatic neuroblastoma, not liver cancer. The following stages are used for neuroblastoma: Stage 1 In stage 1, the tumor is in only one area and all of the tumor that can be seen is completely removed during surgery. Stage 2 Stage 2 is divided into stages 2A and 2B. - Stage 2A: The tumor is in only one area and all of the tumor that can be seen cannot be completely removed during surgery. - Stage 2B: The tumor is in only one area and all of the tumor that can be seen may be completely removed during surgery. Cancer cells are found in the lymph nodes near the tumor. Stage 3 In stage 3, one of the following is true: - the tumor cannot be completely removed during surgery and has spread from one side of the body to the other side and may also have spread to nearby lymph nodes; or - the tumor is in only one area, on one side of the body, but has spread to lymph nodes on the other side of the body; or - the tumor is in the middle of the body and has spread to tissues or lymph nodes on both sides of the body, and the tumor cannot be removed by surgery. Stage 4 Stage 4 is divided into stages 4 and 4S. - In stage 4, the tumor has spread to distant lymph nodes or other parts of the body. - In stage 4S: - the child is younger than 12 months; and - the cancer has spread to the skin, liver, and/or bone marrow; and - the tumor is in only one area and all of the tumor that can be seen may be completely removed during surgery; and/or - cancer cells may be found in the lymph nodes near the tumor. Treatment of neuroblastoma is based on risk groups. For many types of cancer, stages are used to plan treatment. For neuroblastoma, treatment depends on risk groups. The stage of neuroblastoma is one factor used to determine risk group. Other factors are the age of the child, tumor histology, and tumor biology. There are three risk groups: low risk, intermediate risk, and high risk. - Low-risk and intermediate-risk neuroblastoma have a good chance of being cured. - High-risk neuroblastoma may be hard to cure.

Is subcutaneous efalizumab effective in the treatment of alopecia areata?

Numbers were too small for certain analyses.

What is (are) Branchiootorenal syndrome ?

Branchiootorenal syndrome is characterized by birth defects or anomalies of tissues in the neck, malformations of the external ear, hearing loss, and kidney malformations. Symptom and symptom severity can vary greatly from person to person. It can be caused by mutations in the EYA1, SIX1, or SIX5 genes. It is passed through families in an autosomal dominant fashion. Treatment may include surgery to remove the anomalies of the neck (i.e., branchial fistulae or cysts), careful assessment and management of hearing loss, and follow-up by a kidney specialist (nephrologist). In some cases dialysis or kidney transplant may be required.

How many people are affected by campomelic dysplasia ?

The prevalence of campomelic dysplasia is uncertain; estimates range from 1 in 40,000 to 200,000 people.

What to do for Cystocele ?

- A cystocele, also called a prolapsed or dropped bladder, is the bulging or dropping of the bladder into the vagina. - A cystocele occurs when the muscles and supportive tissues between a womans bladder and vagina weaken and stretch, letting the bladder sag from its normal position and bulge into the vagina or through the vaginal opening. - Diagnosing a cystocele requires medical tests and a physical exam of the vagina. - Cystocele treatment depends on the severity of the cystocele and whether a woman has symptoms.

What are the treatments for Duchenne muscular dystrophy ?

There is no known cure for Duchenne muscular dystrophy (DMD). Treatment is aimed at the control of symptoms to maximize the quality of life. Individuals with DMD often experience dilated cardiomyopathy (the heart becomes larger and weaker). This can be treated with medications and in severe cases a heart transplant may be necessary. Assistive devices for breathing difficulties may be needed, especially at night. Physical activity is encouraged for individuals with Duchenne muscular dystrophy. Physical inactivity (such as bed rest) can worsen the muscle disease. Physical therapy may be helpful to maintain muscle strength and function. Orthopedic devices (such as braces and wheelchairs) may improve the ability to move and take care of oneself. Steroids are usually given to individuals with Duchenne muscular dystrophy to help improve the strength and function of muscles. There are a few different steroids that can be used to treat DMD: Prednisone is a steroid that has been shown to extend the ability to walk by 2 to 5 years. However, the possible side effects of prednisone include weight gain, high blood pressure, behavior changes, and delayed growth. Deflazacort (another form of prednisone), is used in Europe and believed to have fewer side effects. Oxandrolone, a medication used in a research study, also has similar benefits to prednisone, but with fewer side effects. Cyclosporine has also been used as a treatment for DMD, and has improved muscle function in children. Although, its use is controversial because it can cause myopathy, which is a muscle disease that causes muscle weakness. There are several other therapies that are also being researched, including exon skipping drugs, coenzyme Q10, idebenone, glutamine, and pentoxifylline.

What is (are) epidermolysis bullosa simplex ?

Epidermolysis bullosa simplex is one of a group of genetic conditions called epidermolysis bullosa that cause the skin to be very fragile and to blister easily. Blisters and areas of skin loss (erosions) occur in response to minor injury or friction, such as rubbing or scratching. Epidermolysis bullosa simplex is one of the major forms of epidermolysis bullosa. The signs and symptoms of this condition vary widely among affected individuals. Blistering primarily affects the hands and feet in mild cases, and the blisters usually heal without leaving scars. Severe cases of this condition involve widespread blistering that can lead to infections, dehydration, and other medical problems. Severe cases may be life-threatening in infancy. Researchers have identified four major types of epidermolysis bullosa simplex. Although the types differ in severity, their features overlap significantly, and they are caused by mutations in the same genes. Most researchers now consider the major forms of this condition to be part of a single disorder with a range of signs and symptoms. The mildest form of epidermolysis bullosa simplex, known as the localized type (formerly called the Weber-Cockayne type), is characterized by skin blistering that begins anytime between childhood and adulthood and is usually limited to the hands and feet. Later in life, skin on the palms of the hands and soles of the feet may thicken and harden (hyperkeratosis). The Dowling-Meara type is the most severe form of epidermolysis bullosa simplex. Extensive, severe blistering can occur anywhere on the body, including the inside of the mouth, and blisters may appear in clusters. Blistering is present from birth and tends to improve with age. Affected individuals also experience abnormal nail growth and hyperkeratosis of the palms and soles. Another form of epidermolysis bullosa simplex, known as the other generalized type (formerly called the Koebner type), is associated with widespread blisters that appear at birth or in early infancy. The blistering tends to be less severe than in the Dowling-Meara type. Epidermolysis bullosa simplex with mottled pigmentation is characterized by patches of darker skin on the trunk, arms, and legs that fade in adulthood. This form of the disorder also involves skin blistering from early infancy, hyperkeratosis of the palms and soles, and abnormal nail growth. In addition to the four major types described above, researchers have identified another skin condition related to epidermolysis bullosa simplex, which they call the Ogna type. It is caused by mutations in a gene that is not associated with the other types of epidermolysis bullosa simplex. It is unclear whether the Ogna type is a subtype of epidermolysis bullosa simplex or represents a separate form of epidermolysis bullosa. Several other variants of epidermolysis bullosa simplex have been proposed, but they appear to be very rare.

What is (are) Zellweger spectrum disorder ?

Zellweger spectrum disorder is a group of conditions that have overlapping signs and symptoms and affect many parts of the body. This group of conditions includes Zellweger syndrome, neonatal adrenoleukodystrophy (NALD), and infantile Refsum disease. These conditions were once thought to be distinct disorders but are now considered to be part of the same condition spectrum. Zellweger syndrome is the most severe form of the Zellweger spectrum disorder, NALD is intermediate in severity, and infantile Refsum disease is the least severe form. Because these three conditions are now considered one disorder, some researchers prefer not to use the separate condition names but to instead refer to cases as severe, intermediate, or mild. Individuals with Zellweger syndrome, at the severe end of the spectrum, develop signs and symptoms of the condition during the newborn period. These infants experience weak muscle tone (hypotonia), feeding problems, hearing and vision loss, and seizures. These problems are caused by the breakdown of myelin, which is the covering that protects nerves and promotes the efficient transmission of nerve impulses. The part of the brain and spinal cord that contains myelin is called white matter. Destruction of myelin (demyelination) leads to loss of white matter (leukodystrophy). Children with Zellweger syndrome also develop life-threatening problems in other organs and tissues, such as the liver, heart, and kidneys. They may have skeletal abnormalities, including a large space between the bones of the skull (fontanels) and characteristic bone spots known as chondrodysplasia punctata that can be seen on x-ray. Affected individuals have distinctive facial features, including a flattened face, broad nasal bridge, and high forehead. Children with Zellweger syndrome typically do not survive beyond the first year of life. People with NALD or infantile Refsum disease, which are at the less-severe end of the spectrum, have more variable features than those with Zellweger syndrome and usually do not develop signs and symptoms of the disease until late infancy or early childhood. They may have many of the features of Zellweger syndrome; however, their condition typically progresses more slowly. Children with these less-severe conditions often have hypotonia, vision problems, hearing loss, liver dysfunction, developmental delay, and some degree of intellectual disability. Most people with NALD survive into childhood, and those with infantile Refsum disease may reach adulthood. In rare cases, individuals at the mildest end of the condition spectrum have developmental delay in childhood and hearing loss or vision problems beginning in adulthood and do not develop the other features of this disorder.

Is juvenile Batten disease inherited ?

This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Is Tubular aggregate myopathy inherited ?

It is evident from family history studies that the condition can be passed through families in either an autosomal dominant or autosomal recessive fashion. Some cases appear to be due to dominant mutations in the STIM1 gene. Sporadic cases of tubular aggregate myopathy have also been reported. Sporadic is used to denote either a genetic disorder that occurs for the first time in a family due to a new mutation or the chance occurrence of a non-genetic disorder or abnormality that is not likely to recur in a family.

What is (are) X-linked chondrodysplasia punctata 1 ?

X-linked chondrodysplasia punctata 1 is a disorder of cartilage and bone development that occurs almost exclusively in males. Chondrodysplasia punctata is an abnormality that appears on x-rays as spots (stippling) near the ends of bones and in cartilage. In most infants with X-linked chondrodysplasia punctata 1, this stippling is seen in bones of the ankles, toes, and fingers; however, it can also appear in other bones. The stippling generally disappears in early childhood. Other characteristic features of X-linked chondrodysplasia punctata 1 include short stature and unusually short fingertips and ends of the toes. This condition is also associated with distinctive facial features, particularly a flattened-appearing nose with crescent-shaped nostrils and a flat nasal bridge. People with X-linked chondrodysplasia punctata 1 typically have normal intelligence and a normal life expectancy. However, some affected individuals have had serious or life-threatening complications including abnormal thickening (stenosis) of the cartilage that makes up the airways, which restricts breathing. Also, abnormalities of spinal bones in the neck can lead to pinching (compression) of the spinal cord, which can cause pain, numbness, and weakness. Other, less common features of X-linked chondrodysplasia punctata 1 include delayed development, hearing loss, vision abnormalities, and heart defects.

Does ketamine attenuate endotoxin-induced leukocyte adherence in rat mesenteric venules?

Pretreatment with ketamine attenuates endotoxin-induced leukocyte adherence by a shear rate-independent mechanism, suggesting reduced expression of adhesion molecules. These results indicate that ketamine exerts an anti-inflammatory effect, which might be beneficial in septic patients.

Is toll-like receptor 2 required for autoantibody production and development of renal disease in pristane-induced lupus?

TLR-2 is required for the production of prototypical lupus autoantibodies and the development of renal disease in pristane-induced murine lupus. Interference with TLR-2 signaling may be a promising novel strategy for the treatment of SLE.

What are the treatments for Neurosarcoidosis ?

There is no agreed upon standard of treatment for neurosarcoidosis. Doctors generally recommend corticosteroid therapy as first-line therapy for individuals with the condition. Additional treatment with immunomodulatory drugs such as hydroxychloroquine, pentoxyfilline, thalidomide, and infliximab, and immunosuppressive drugs such as methotrexate, azathioprine, cyclosporin, and cyclophosphamide, have benefited some individuals. While the use of corticosteroids and other immunosuppressive drugs is effective, these medications also have undesirable side effects. Side effects and experience with certain drugs may play a role in medication choices.

What are the stages of Childhood Acute Myeloid Leukemia and Other Myeloid Malignancies ?

Key Points - Once childhood acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body. - There is no standard staging system for childhood AML, childhood chronic myelogenous leukemia (CML), juvenile myelomonocytic leukemia (JMML), or myelodysplastic syndromes (MDS). Once childhood acute myeloid leukemia (AML) has been diagnosed, tests are done to find out if the cancer has spread to other parts of the body. The following tests and procedures may be used to determine if the leukemia has spread: - Lumbar puncture : A procedure used to collect a sample of cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that leukemia cells have spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. - Biopsy of the testicles, ovaries, or skin: The removal of cells or tissues from the testicles, ovaries, or skin so they can be viewed under a microscope to check for signs of cancer. This is done only if something unusual about the testicles, ovaries, or skin is found during the physical exam. There is no standard staging system for childhood AML, childhood chronic myelogenous leukemia (CML), juvenile myelomonocytic leukemia (JMML), or myelodysplastic syndromes (MDS). The extent or spread of cancer is usually described as stages. Instead of stages, treatment of childhood AML, childhood CML, JMML, and MDS is based on one or more of the following: - The type of disease or the subtype of AML. - Whether leukemia has spread outside the blood and bone marrow. - Whether the disease is newly diagnosed, in remission, or recurrent. Newly diagnosed childhood AML Newly diagnosed childhood AML has not been treated except to relieve signs and symptoms such as fever, bleeding, or pain, and one of the following is true: - More than 20% of the cells in the bone marrow are blasts (leukemia cells). or - Less than 20% of the cells in the bone marrow are blasts and there is a specific change in the chromosome. Childhood AML in remission In childhood AML in remission, the disease has been treated and the following are true: - The complete blood count is almost normal. - Less than 5% of the cells in the bone marrow are blasts (leukemia cells). - There are no signs or symptoms of leukemia in the brain, spinal cord, or other parts of the body.

What are the symptoms of Hereditary sensory and autonomic neuropathy type V ?

The Human Phenotype Ontology provides the following list of signs and symptoms for Hereditary sensory and autonomic neuropathy type V. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Anhidrosis 7.5% Episodic fever 5% Intellectual disability, mild 5% Acral ulceration and osteomyelitis leading to autoamputation of digits - Acral ulceration and osteomyelitis leading to autoamputation of the digits (feet) - Autosomal recessive inheritance - Infantile onset - Pain insensitivity - Painless fractures due to injury - Self-mutilation - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Is muscle atrophy as pre-sarcopenia in Japanese patients with chronic liver disease : computed tomography useful for evaluation?

Retrospective evaluate for pre-sarcopenia was easy to perform with CT findings. Nutrition and exercise instruction should be considered for early stage and even non-elderly CLD as well as LC.

Is insecure attachment associated with paranoia but not hallucinations in psychotic patients : the mediating role of negative self-esteem?

It may be fruitful to explore attachment representations in psychological treatments for paranoid patients. If future research confirms the importance of disrupted attachment as a risk factor for persecutory delusions, consideration might be given to how to protect vulnerable young people, for example those raised in children's homes.

What are the genetic changes related to Horner syndrome ?

Although congenital Horner syndrome can be passed down in families, no associated genes have been identified. Horner syndrome that appears after the newborn period (acquired Horner syndrome) and most cases of congenital Horner syndrome result from damage to nerves called the cervical sympathetics. These nerves belong to the part of the nervous system that controls involuntary functions (the autonomic nervous system). Within the autonomic nervous system, the nerves are part of a subdivision called the sympathetic nervous system. The cervical sympathetic nerves control several functions in the eye and face such as dilation of the pupil and sweating. Problems with the function of these nerves cause the signs and symptoms of Horner syndrome. Horner syndrome that occurs very early in life can lead to iris heterochromia because the development of the pigmentation (coloring) of the iris is under the control of the cervical sympathetic nerves. Damage to the cervical sympathetic nerves can be caused by a direct injury to the nerves themselves, which can result from trauma that might occur during a difficult birth, surgery, or accidental injury. The nerves related to Horner syndrome can also be damaged by a benign or cancerous tumor, for example a childhood cancer of the nerve tissues called a neuroblastoma. Horner syndrome can also be caused by problems with the artery that supplies blood to the head and neck (the carotid artery) on the affected side, resulting in loss of blood flow to the nerves. Some individuals with congenital Horner syndrome have a lack of development (agenesis) of the carotid artery. Tearing of the layers of the carotid artery wall (carotid artery dissection) can also lead to Horner syndrome. The signs and symptoms of Horner syndrome can also occur during a migraine headache. When the headache is gone, the signs and symptoms of Horner syndrome usually also go away. Some people with Horner syndrome have neither a known problem that would lead to nerve damage nor any history of the disorder in their family. These cases are referred to as idiopathic Horner syndrome.

Does carbidopa pretreatment improve image interpretation and visualisation of carcinoid tumours with 11C-5-hydroxytryptophan positron emission tomography?

We conclude that CD premedication improves 11C-5-HTP PET image quality and facilitates detection of NET lesions. Because of the similarity of metabolic pathways, this method could probably be applied to improve PET imaging using other tracers like 18F-DOPA and 11C-DOPA.

Is perioperative allogenenic blood transfusion associated with worse clinical outcomes for hepatocellular carcinoma : a meta-analysis?

The findings from the current meta-analysis demonstrated that ABT was associated with adverse clinical outcomes for HCC patients undergoing surgery, including increased death, recurrence and complications. Therefore, ABT should not be performed if possible.
