<s>[INST] What are the treatments for Multiple pterygium syndrome Escobar type ? [/INST] How is multiple pterygium syndrome, Escobar type treated? There is currently no cure for multiple pterygium syndrome, Escobar type. As a result treatment is aimed at managing the associated symptoms. Orthopedics should be involved for issues arising from scoliosis. Infections should be treated promptly. Contracture releases have been performed with variable outcome. Physical therapy is important to help minimize contractures. When ptosis (droopy eyelids) is present, the patient should be referred to ophthalmology. Patients should also be referred to audiology due to the risk of conductive hearing loss. </s></s>

<s>[INST] What is (are) Femoral facial syndrome ? [/INST] Femoral-facial syndrome is characterized by underdevelopment of the thigh bones and certain facial features, which may include upslanting eyes, short nose with a broad tip, long space between the nose and upper lip (philtrum), thin upper lip, small or underdeveloped lower jaw (micrognathia), and cleft palate. Symptoms may affect one or both sides of the face and limbs. Cleft palate has been reported only in females. Other signs and symptoms occur variably. Intellectual development has been reported as normal. In most cases the cause of the condition is unknown (sporadic). Some cases have been reported in association with diabetes during pregnancy (maternal diabetes). There have been rare reports (three cases) describing a family with more than one affected member. </s></s>

<s>[INST] Is Femoral facial syndrome inherited ? [/INST] Is femoral facial syndrome inherited? The vast majority of cases of femoral facial syndrome (FFS) have been sporadic, not inherited. When a condition is sporadic, it means that it occurs in an individual who has no history of the condition in his/her family. Occurrence in more than one family member has been reported in three cases, but no sibling recurrences have been reported. Maternal diabetes has been recognized as a major factor causing FFS in more than 20% of the reported cases. The circumstances of the reported cases in the literature support non-genetic causes of FFS, such as teratogenic exposure. It is theoretically possible that the cause could sometimes be a new gene mutation occurring in the affected individual, or autosomal dominant inheritance with reduced penetrance. </s></s>

<s>[INST] What is (are) Mixed connective tissue disease ?

<s>[INST] What are the treatments for Mixed connective tissue disease ? [/INST] How might mixed connective tissue disease be treated? There is currently no cure for mixed connective tissue disease (MCTD). However, treatments can help manage symptoms of the condition. For example, medications such as over-the-counter or prescription nonsteroidal anti-inflammatory drugs may help with inflammation and pain of the muscles or joints. Glucocorticoids may be recommended in certain situations, such as during disease flares or when complications arise (e.g., aseptic meningitis, myositis, pleurisy, pericarditis, and myocarditis). Some people with MCTD require long term use of immunosuppressant medications. Additional medications may be prescribed based on the signs and symptoms present in each person. For example, if a person with MCTD has developed symptoms similar to those of lupus, medications typically prescribed for people with lupus may be recommended.

<s>[INST] What is (are) Osteochondritis dissecans ? [/INST] Osteochondritis dissecans is a joint condition that occurs when a piece of cartilage and the thin layer of bone beneath it, separates from the end of the bone. If the piece of cartilage and bone remain close to where they detached, they may not cause any symptoms. However, affected people may experience pain, weakness and/or decreased range of motion in the affected joint if the cartilage and bone travel into the joint space. Although osteochondritis dissecans can affect people of all ages, it is most commonly diagnosed in people between the ages of 10 and 20 years. In most cases, the exact underlying cause is unknown. Rarely, the condition can affect more than one family member (called familial osteochondritis dissecans); in these cases, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene and is inherited in an autosomal dominant manner. Treatment for the condition varies depending on many factors, including the age of the affected person and the severity of the symptoms, but may include rest; casting or splinting; surgery and/or physical therapy. </s></s>

<s>[INST] What causes Osteochondritis dissecans ? [/INST] What causes osteochondritis dissecans? In most cases, the exact underlying cause of osteochondritis dissecans is not completely understood. Scientists suspect that it may be due to decreased blood flow to the end of the affected bone, which may occur when repetitive episodes of minor injury and/or stress damage a bone overtime. In some families, osteochondritis dissecans is caused by changes (mutations) in the ACAN gene. In these cases, which are referred to as familial osteochondritis dissecans, the condition generally affects multiple joints and is also associated with short stature and early-onset osteoarthritis. The ACAN gene encodes a protein that is important to the structure of cartilage. Mutations in this gene weaken cartilage, which leads to the various signs and symptoms of familial osteochondritis disssecans. </s></s>

<s>[INST] How to diagnose Osteochondritis dissecans ? [/INST] How is osteochondritis dissecans diagnosed? A diagnosis of osteochondritis dissecans is usually suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis.

<s>[INST] What are the treatments for Osteochondritis dissecans ? [/INST] How might osteochondritis dissecans be treated? The primary aim of treatment for osteochondritis dissecans is to restore normal function of the affected joint, relieve pain and prevent osteoarthritis. Treatment for the condition varies depending on many factors including the age of the affected person and the severity of the symptoms. In children and young teens, osteochondritis dissecans often heals overtime without surgical treatment. These cases are often managed with rest and in some cases, crutches and/or splinting to relieve pain and swelling. If non-surgical treatments are not successful or the case is particularly severe (i.e. the cartilage and bone are moving around within the joint space), surgery may be recommended. Following surgery, physical therapy is often necessary to improve the strength and range of motion of the affected joint. </s></s>

<s>[INST] What is (are) Schindler disease type 1 ? [/INST] Schindler disease is an inherited condition that primarily causes neurological problems. There are three types of Schindler disease. Schindler disease type 1, also called the infantile type, is the most severe form. Babies with this condition appear healthy a birth, but by the age of 8 to 15 months they stop developing new skills and begin losing skills they had already acquired. As the condition progresses, affected individuals develop blindness and seizures, and eventually lose awareness of their surroundings and become unresponsive. People with this form of the condition usually don't survive past early childhood. Schindler disease type 1 is caused by mutations in the NAGA gene.

<s>[INST] What causes Schindler disease type 1 ? [/INST] What causes Schindler disease type 1? Schindler disease type 1 is caused by mutations in the NAGA gene. This gene provides instructions for making the enzyme alpha-N-acetylgalactosaminidase.This enzyme works in the lysosomes (compartments within cells that digest and recycle materials) to help break down complexes called glycoproteins and glycolipids (sugar molecules attached to certain proteins and fats). More specifically, alpha-N-acetylgalactosaminidase helps remove a molecule called alpha-N-acetylgalactosamine from sugars in these complexes. Mutations in the NAGA gene interfere with the ability of the alpha-N-acetylgalactosaminidase enzyme to perform its role in breaking down glycoproteins and glycoliipids. These substances accumulate in the lysosomes and cause cells to malfunction and eventually die. Cell damage in the nervous system and other tissues and organs of the body leads to the signs and symptoms of Schindler disease type 1. </s></s>

<s>[INST] Is Schindler disease type 1 inherited ? [/INST] How is Schindler disease type 1 inherited? Schindler disease type 1 is inherited in an autosomal recessive pattern. This means that both copies of the gene in each cell have mutations.

<s>[INST] What is (are) Adenoid cystic carcinoma ? [/INST] Adenoid cystic carcinoma (ACC) is a rare form of adenocarcinoma, which is cancer that begins in gladular tissues. ACC most commonly arises in the head and neck, in various parts of the major and minor salivary glands including the palate, nasopharynx, lining of the mouth, voice box (larynx) or windpipe (trachea). It can also occur in the breast, uterus, or other locations in the body. Early symptoms depend on the tumor's location and may include lumps under the lining of the mouth or facial skin; numbness in the mouth or face; difficulty swallowing; hoarseness; pain; or paralysis of a facial nerve. ACC often has long periods with no growth followed by growth spurts; however, it can be aggressive in some people. ACC spreads along nerves or through the bloodstream, and only spreads to the lymph nodes in about 5-10% of cases. The cause of ACC is currently unknown. Treatment depends on many factors and may include surgery, radiation, and/or chemotherapy. </s></s>

<s>[INST] What causes Adenoid cystic carcinoma ? [/INST] What causes adenoid cystic carcinoma? The underlying cause of adenoid cystic carcinoma (ACC) is not yet known, and no strong genetic or environmental risk factors specific to ACC have been identified. Researchers believe that a combination of various genetic and environmental factors probably interact to ultimately cause a person to develop specific types of cancers. There is ongoing research to learn more about the many factors that contribute to the development of cancer. Cancer is at least partly due to acquired (not inherited) damage or changes to the DNA in certain cells. For example, various studies have shown that chromosomal abnormalities and genetic deletions are present in samples of ACC. However, these genetic abnormalities are present only in the cancer cells, not in the cells with the genetic material that is passed on to offspring (the egg and sperm cells). </s></s>

<s>[INST] Is Adenoid cystic carcinoma inherited ? [/INST] Is adenoid cystic carcinoma inherited? While the underlying cause of adenoid cystic carcinoma (ACC) is not known, no strong genetic risk factors have been identified. To our knowledge, only one case of apparent familial ACC has been reported worldwide. In this case, a father and daughter were both affected with ACC of the sublingual salivary gland. While ACC appears to generally be sporadic (occurring in people with no family history of ACC), there has been speculation about a possible linkage between salivary gland cancers in general and inherited BRCA gene mutations. However, this potential link needs further investigation. There has also been one report of a case of ACC of the salivary gland occurring in a person with basal cell nevus syndrome, a hereditary syndrome known to predispose affected people to a very wide range of tumors. </s></s>

<s>[INST] What is (are) Ornithine transcarbamylase deficiency ? [/INST] Ornithine transcarbamylase (OTC) deficiency is an inherited disorder that causes ammonia to accumulate in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if the levels become too high. The nervous system is especially sensitive to the effects of excess ammonia. The signs and symptoms of OTC deficiency may include development delay, intellectual disability and liver problems. It is caused by changes (mutations) in the OTC gene. OTC deficiency is inherited as an X-linked condition. Treatment consists of not eating protein, taking certain medications and having hemodialysis, if needed. </s></s>

<s>[INST] What causes Ornithine transcarbamylase deficiency ? [/INST] What causes ornithine transcarbamylase (OTC) deficiency? Ornithine transcarbamylase (OTC) deficiency is caused by mutations in the OTC gene. OTC deficiency belongs to a class of genetic diseases called urea cycle disorders. The urea cycle is a sequence of reactions that occurs in liver cells. It processes excess nitrogen, generated when protein is used by the body, to make a compound called urea that is excreted by the kidneys. In OTC deficiency, the enzyme that starts a specific reaction within the urea cycle is damaged or missing. The urea cycle cannot proceed normally, and nitrogen accumulates in the bloodstream in the form of ammonia. Ammonia is especially damaging to the nervous system, so OTC deficiency causes neurological problems as well as eventual damage to the liver. </s></s>

<s>[INST] Is Ornithine transcarbamylase deficiency inherited ? [/INST] How is ornithine transcarbamylase (OTC) deficiency inherited? Ornithine transcarbamylase (OTC) deficiency is an X-linked disorder. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), mutations in both copies of the gene will cause the disorder. Some females with only one altered copy of the OTC gene also show signs and symptoms of OTC deficiency. </s></s>

The thickened bones can lead to pain in the arms and legs, a waddling walk, muscle weakness, and extreme tiredness. The age at which affected individuals first experience symptoms varies greatly; however, most people with this condition develop pain or weakness by adolescence. Camurati-Engelmann disease is caused by a mutation in the TGFB1 gene which is inherited in an autosomal dominant fashion. In some instances, people have the gene mutation that causes Camurati-Engelmann disease but never develop the characteristic features of this condition. In others, features are present, but a mutation cannot be identified. These cases are referred to as Camurati-Engelmann disease type II.

<s>[INST] What are the symptoms of Camurati-Engelmann disease ? [/INST] What are the signs and symptoms of Camurati-Engelmann disease? People with Camurati-Engelmann disease have increased bone density, particularly affecting the long bones of the arms and legs (tibia, femur, humerus, ulna, radius). In some cases, the skull and hip bones are also affected. The thickened bones can lead to pain in the arms and legs, a waddling walk, muscle weakness, and extreme tiredness. An increase in the density of the skull results in increased pressure on the brain and can cause a variety of neurological problems, including headaches, hearing loss, vision problems, dizziness (vertigo), ringing in the ears (tinnitus), and facial paralysis. The added pressure that thickened bones put on the muscular and skeletal systems can cause abnormal curvature of the spine (scoliosis), joint deformities (contractures), knock knees, and flat feet (pes planus). Other features of Camurati-Engelmann disease include abnormally long limbs in proportion to height, a decrease in muscle mass and body fat, and delayed puberty. In the most severe cases, the mandibula (jaw), vertebrae, thoracic cage, shoulder girdle, and carpal (hands, wrist) and tarsal (foot, ankle) bones are involved. Radiographically (on X-ray), the shafts of long bones show symmetric and progressive widening and malformation (diaphyseal dysplasia). Vascular (Raynaud's phenomenon) and hematological (anemia, leukopenia (low level of white blood cells), increased erythrocyte sedimentation rate) features and hepatosplenomegaly are commonly associated with the disease.

<s>[INST] What causes Camurati-Engelmann disease ? [/INST] What causes Camurati-Engelmann disease? Mutations in the TGFB1 gene cause Camurati-Engelmann disease. The TGFB1 gene provides instructions for producing a protein called transforming growth factor beta-1 (TGF-1). The TGF-1 protein helps control the growth and division (proliferation) of cells, the process by which cells mature to carry out specific functions (differentiation), cell movement (motility), and the self-destruction of cells (apoptosis). The TGF-1 protein is found throughout the body and plays a role in development before birth, the formation of blood vessels, the regulation of muscle tissue and body fat development, wound healing, and immune system function. TGF-1 is particularly abundant in tissues that make up the skeleton, where it helps regulate bone growth, and in the intricate lattice that forms in the spaces between cells (the extracellular matrix). Within cells, the TGF-1 protein is turned off (inactive) until it receives a chemical signal to become active. The TGFB1 gene mutations that cause Camurati-Engelmann disease result in the production of a TGF-1 protein that is always turned on (active). Overactive TGF-1 proteins lead to increased bone density and decreased body fat and muscle tissue, contributing to the signs and symptoms of Camurati-Engelmann disease. Some individuals with Camurati-Engelmnan disease do not have identified mutations in the TGFB1 gene. In these cases, the cause of the condition is unknown. </s></s>

In some cases, an affected person inherits the mutated gene from an affected parent. In other cases, the mutation occurs for the first time in a person with no family history of the condition. This is called a de novo mutation. When a person with a mutation that causes an autosomal dominant condition has children, each child has a 50% (1 in 2) chance to inherit that mutation. </s></s>

NSAIDs and bisphosphonates have not been proven to be effective for most people with CED. Corticosteroids may relieve some of the symptoms such as pain and weakness and can also improve gait and exercise tolerance, however corticosteroids have serious side effects with long term use. More recently, losartan, an angiotensin II type 1 receptor antagonist, has been reported to reduce limb pain and increase muscle strength in multiple case reports. However, the effectiveness of losartan needs more study to determine if it is effective for those with CED and without major side effects. Exercise programs when they are tolerated have also been found to be beneficial. Please note, case reports report the clinical findings associated with individual cases. It is important to keep in mind that the clinical findings documented in these case reports are based on specific individuals and may differ from one affected person to another. </s></s>

<s>[INST] What is (are) Periventricular heterotopia ?

Intelligence is generally normal; however, some affected people may have mild intellectual disability, including difficulty with reading and/or spelling. Less common signs and symptoms include microcephaly, developmental delay, recurrent infections, and blood vessel abnormalities. Some cases are caused by changes (mutations) in the FLNA gene and are inherited in an X-linked dominant manner. Others are caused by mutations in the ARFGEF2 gene and are inherited in an autosomal recessive manner. Rarely, periventricular heterotopia is associated with duplication of genetic material on chromosome 5. Treatment is generally focused on managing recurrent seizures with medications. </s></s>

<s>[INST] What are the symptoms of Periventricular heterotopia ? [/INST] What are the signs and symptoms of periventricular nodular heterotopia? The condition is first noticed when seizures appear, often during the teenage years. The nodules around the ventricles are then typically discovered when magnetic resonance imaging (MRI) studies are done. Patients usually have normal intelligence, although some have mild intellectual disability. Difficulty with reading and spelling (dyslexia) has been reported in some girls with periventricular heterotopia. Less commonly, individuals with periventricular heterotopia may have more severe brain malformations, small head size (microcephaly), developmental delays, recurrent infections, blood vessel abnormalities, or other problems. In the X-linked form of periventricular nodular heterotopia, affected patients are mostly females because in males the symptoms are too serious and they die before birth. The following clinical features have been reported: seizure disorder, mental problems, heart anomalies, stomach immobility, strabismus, short fingers and dyslexia. Periventricular heterotopia may also occur in association with other conditions such as Ehlers-Danlos syndrome (Ehlers-Danlos with periventricular heterotopia) which results in extremely flexible joints, skin that stretches easily, and fragile blood vessels. In the autosomal recessive form of periventricular heterotopia the disorder is severe and may include microcephaly, severe developmental delay, and seizures beginning in infancy. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show any signs or symptoms of this condition. </s></s>

It is recommended that patients with the X-linked form of the disease have studies evaluating the carotid artery and an abdominal ultrasound because of the risk for aortic or carotid dissection or other vascular anomalies.[1823] Treatment also include surgery for removal of the lesion and more recently, laser ablation guided with magnetic resonance. </s></s>

<s>[INST] What is (are) Hermansky-Pudlak syndrome ? [/INST] Hermansky-Pudlak syndrome is a multisystem, genetic condition characterized by blood platelet dysfunction with prolonged bleeding, visual impairment, and abnormally light coloring of the skin, hair, and eyes (oculocutaneous albinism). Long-term sun exposure greatly increases the risk of skin damage and skin cancers. Some individuals have colitis, kidney failure, and pulmonary fibrosis. Symptoms of pulmonary fibrosis usually appear during the early thirties and rapidly worsen. This condition is inherited in an autosomal recessive fashion. Treatment is symptomatic and supportive. There are nine different types of Hermansky-Pudlak syndrome, which can be distinguished by their signs and symptoms and underlying genetic cause. Types 1 and 4 are the most severe forms. Types 1, 2, and 4 are the only types associated with pulmonary fibrosis. Individuals with type 3, 5, or 6 have the mildest symptoms of all the types. Little is known about the signs, symptoms, and severity of types 7, 8 and 9. </s></s>

<s>[INST] What is (are) Schistosomiasis ? [/INST] Schistosomiasis is a disease caused by parasitic worms. Although the worms that cause schistosomiasis are not found in the United States, more than 200 million people are infected worldwide. Infection occurs through contact with contaminated water. The parasite in its infective stages is called a cercaria. It swims freely in open bodies of water. On contact with humans, the parasite burrows into the skin, matures into another stage (schistosomula), then migrates to the lungs and liver, where it matures into the adult form. The adult worm then migrates to its preferred body part (bladder, rectum, intestines, liver, portal venous system (the veins that carry blood from the intestines to liver, spleen, lungs), depending on its species. Schistosomiasis is common in many tropical and subtropical areas worldwide. It can be treated safely and effectively with praziquantel. </s></s>

<s>[INST] How to diagnose Schistosomiasis ? [/INST] How is schistosomiasis diagnosed? Examination of stool and/or urine for ova is the primary method of diagnosis for schistosomiasis. The choice of sample depends on the suspected species, which may be determined by careful review of travel and residence history. The sensitivity of this testing can be limited by the intensity of infection. For best results, three samples should be collected on different days. A blood sample can also be tested for evidence of infection. Blood tests are indicated for travelers or immigrants from endemic areas who have not been treated (or not treated appropriately) in the past. The most common tests detect antibodies to the adult worm. For accurate results, the blood sample tested should be collected at least 6 to 8 weeks after likely infection. Blood testing may not be appropriate for patients who have been repeatedly infected and treated in the past because antibodies can persist despite cure. In these patients, blood testing cannot distinguish between a past or current infection. A specific blood test has been developed for this population (which can detect an active infection based on the presence of schistosomal antigen), but this test is not commercially available in the United States and is currently being studied for its ability to detect mild infections. </s></s>

People affected by this condition may experience a headache and fever for up to 5 days, followed by personality and behavioral changes; seizures; hallucinations; and altered levels of consciousness. Without early diagnosis and treatment, severe brain damage or even death may occur. Herpes simplex encephalitis is caused by a virus called the herpes simplex virus. Most cases are associated with herpes simplex virus type I (the cause of cold sores or fever blisters), although rare cases can be caused by herpes simplex virus type II (genital herpes). It is poorly understood why some people who are infected with herpes simplex virus develop herpes simplex encephalitis while others do not. Changes (mutations) in genes such as TLR3 and TRAF3 have been observed suggesting there may be a genetic component in some cases. Treatment consists of antiviral therapy. </s></s>

The signs and symptoms of Carpenter syndrome can vary greatly, even within members of the same family. The main features include premature closure of certain skull bones (craniosynostosis), distinctive facial characteristics, and/or abnormalities of the fingers and toes (digits). People with Carpenter syndrome often have intellectual disability (from mild to profound), but some affected people have normal intelligence. Craniosynostosis prevents the skull from growing normally and can cause a pointed appearance of the head; asymmetry of the head and face; increased pressure within the skull; and characteristic facial features. Facial features may include a flat nasal bridge; down-slanting palpebral fissures (the outside corners of the eye); low-set and abnormally shaped ears; underdeveloped jaws; and abnormal eye shape. Vision problems are common. Some people also have dental abnormalities such as small baby teeth. Abnormalities of the fingers and toes may include fusion of the skin between digits; short digits; or extra digits. Other signs and symptoms may include obesity, umbilical hernia, hearing loss, heart defects, and other skeletal abnormalities such as as deformed hips, kyphoscoliosis, and knees that angle inward.

As the disease progresses, individuals become weaker are are eventually wheelchair-dependent. Death often results from respiratory failure within 2 to 10 years after the onset of symptoms. Most affected individuals have a sporadic (not inherited) form of ALS; about 5-10% have a familial (inherited) form of the condition. Familial ALS may caused by mutations in any one of several genes and the pattern of inheritance varies depending on the gene involved. Treatment is generally supportive. </s></s>

<s>[INST] What causes Amyotrophic lateral sclerosis ? [/INST] What causes amyotrophic lateral sclerosis? In approximately 90-95% of cases the cause of amyotrophic lateral sclerosis (ALS) is unknown and is sporadic (occurring in individuals with no history of the condition in the family). The remaining 5-10% of cases are genetic (familial), often occurring in individuals with a family history of the condition. Mutations in any of several genes, including the C9orf72, SOD1, TARDBP, FUS, ANG, ALS2, SETX, and VAPB genes, can cause familial ALS and may contribute to the development of sporadic ALS. About 60% of individuals with familial ALS have an identifiable genetic mutation; the genetic cause in the remaining cases is unknown. The genes associated with ALS appear to play a role in how neurons function or are involved in regulating the production of various proteins. Over the years, various types of environmental exposures have been proposed as possible contributors to the cause of ALS, including mercury, manganese, products used in farming (fertilizers, insecticides, herbicides), and physical and dietary factors. Exposures have been suggested as a possible explanation for the increased incidence of ALS in Gulf War veterans. Further investigation is ongoing. </s></s>

<s>[INST] Is Amyotrophic lateral sclerosis inherited ? [/INST] Is amyotrophic lateral sclerosis (ALS) inherited? About 90-95% percent of cases of ALS are not inherited and occur in individuals with no history of the condition in their family. The remaining 5-10% of cases are familial, and are thought to be caused by mutations in any one of several genes. The inheritance pattern associated with familial ALS varies depending on the disease-causing gene involved. Most familial cases are inherited in an autosomal dominant manner. This means that only one altered (mutated) copy of the disease-causing gene in each cell is sufficient to cause the condition. In most of these cases, an affected individual has one parent with the condition. When an individual with an autosomal dominant form of ALS has children, each child has a 50% (1 in 2) risk to inherited the mutated copy of the gene and be affected. Less frequently, ALS is inherited in an autosomal recessive manner. In autosomal recessive inheritance, both copies of the disease-causing gene (typically one copy inherited from each parent) must have a mutation for the individual to be affected. The parents of an individual with an autosomal recessive condition, who presumably each carry one mutated copy of the gene, are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers for the same condition are having children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each parent, and a 25% risk to not have the condition and not be a carrier. Autosomal recessive forms of ALS may be mistaken for non-inherited (sporadic) forms due to having a negative family history of the condition. In rare cases, ALS is inherited in an X-linked dominant manner. This occurs when the disease-causing gene is located on the X chromosome (a sex chromosome). Although females have 2 X chromosomes, having a mutation in one X chromosome is still sufficient to cause the condition. Males who have a mutation (and only one X chromosome) will have the condition. Usually, males with an X-linked dominant form of ALS experience more severe symptoms than females with the same form. Some individuals who do inherit a mutation known to cause ALS never develop signs and symptoms of ALS, although the reason for this is unclear. This phenomenon is referred to as reduced penetrance. </s></s>

<s>[INST] What are the treatments for Amyotrophic lateral sclerosis ? [/INST] How might amyotrophic lateral sclerosis (ALS) be treated? The Food and Drug Administration (FDA) has approved the first drug treatment for the diseaseriluzole (Rilutek). Riluzole is believed to reduce damage to motor neurons by decreasing the release of glutamate. Clinical trials with ALS patients showed that riluzole prolongs survival by several months, mainly in those with difficulty swallowing. The drug also extends the time before a patient needs ventilation support. Riluzole does not reverse the damage already done to motor neurons, and patients taking the drug must be monitored for liver damage and other possible side effects. Other treatments for ALS are designed to relieve symptoms and improve the quality of life for patients (palliative care). This supportive care is typically provided by multidisciplinary teams of health care professionals such as physicians; pharmacists; physical, occupational, and speech therapists; nutritionists; social workers; and home care and hospice nurses. Working with patients and caregivers, these teams can design an individualized plan of medical and physical therapy and provide special equipment aimed at keeping patients as mobile and comfortable as possible. </s></s>

<s>[INST] What is (are) Trigeminal neuralgia ? [/INST] Trigeminal neuralgia is a nerve disorder that causes a stabbing or electric-shock-like pain in parts of the face. The pain lasts a few seconds to a few minutes, and usually on only one side of the face. It can also cause muscle spasms in the face the same time as the pain. The pain may result from a blood vessel pressing against the trigeminal nerve (the nerve that carries pain, feeling, and other sensations from the brain to the skin of the face), as a complication of multiple sclerosis, or due to compression of the nerve by a tumor or cyst. In some cases, the cause is unknown. Treatment options include medicines, surgery, and complementary approaches. </s></s>

<s>[INST] What are the treatments for Trigeminal neuralgia ? [/INST] How might trigeminal neuralgia be treated? Treatment options include medicines, surgery, and complementary approaches. Anticonvulsant medicinesused to block nerve firingare generally effective in treating trigeminal neuralgia. These drugs include carbamazepine, oxcarbazepine, topiramate, clonazepam, phenytoin, lamotrigine, and valproic acid. Gabapentin or baclofen can be used as a second drug to treat trigeminal neuralgia and may be given in combination with other anticonvulsants. Tricyclic antidepressants such as amitriptyline or nortriptyline are used to treat pain described as constant, burning, or aching. Typical analgesics and opioids are not usually helpful in treating the sharp, recurring pain caused by trigeminal neuralgia. If medication fails to relieve pain or produces intolerable side effects, surgical treatment may be recommended. Several neurosurgical procedures are available to treat trigeminal neuralgia. The choice among the various types depends on the patient's preference, physical well-being, previous surgeries, presence of multiple sclerosis, and area of trigeminal nerve involvement. Some procedures are done on an outpatient basis, while others may involve a more complex operation that is performed under general anesthesia. Some degree of facial numbness is expected after most of these procedures, and trigeminal neuralgia might return despite the procedures initial success. Depending on the procedure, other surgical risks include hearing loss, balance problems, infection, and stroke. A rhizotomy is a procedure in which select nerve fibers are destroyed to block pain. A rhizotomy for trigeminal neuralgia causes some degree of permanent sensory loss and facial numbness. Several forms of rhizotomy are available to treat trigeminal neuralgia: Balloon compression works by injuring the insulation on nerves that are involved with the sensation of light touch on the face. Glycerol injection involves bathing the ganglion (the central part of the nerve from which the nerve impulses are transmitted) and damaging the insulation of trigeminal nerve fibers. Radiofrequency thermal lesioning involves gradually heating part of the nerve with an electrode, injuring the nerve fibers. Stereotactic radiosurgery uses computer imaging to direct highly focused beams of radiation at the site where the trigeminal nerve exits the brainstem. This causes the slow formation of a lesion on the nerve that disrupts the transmission of pain signals to the brain. Microvascular decompression is the most invasive of all surgeries for trigeminal neuralgia, but it also offers the lowest probability that pain will return. While viewing the trigeminal nerve through a microscope, the surgeon moves away the vessels that are compressing the nerve and places a soft cushion between the nerve and the vessels. Unlike rhizotomies, there is usually no numbness in the face after this surgery. A neurectomy, which involves cutting part of the nerve, may be performed during microvascular decompression if no vessel is found to be pressing on the trigeminal nerve. Some patients choose to manage trigeminal neuralgia using complementary techniques, usually in combination with drug treatment. These therapies offer varying degrees of success. Options include acupuncture, biofeedback, vitamin therapy, nutritional therapy, and electrical stimulation of the nerves. More detailed information regarding the management of trigeminal neuralgia can be found through the National Institute of Neurological Disorders and Stroke and eMedicine. </s></s>

<s>[INST] What is (are) Inclusion body myopathy 2 ? [/INST] Inclusion body myopathy 2, also known as hereditary inclusion body myopathy (HIBM), GNE-related myopathy, distal myopathy with rimmed vacuoles, and Nonaka myopathy, is an inherited condition that primarily affects the skeletal muscles (the muscles that the body uses to move). This disorder is characterized by muscle weakness that appears in late adolescence or early adulthood and worsens over time. Early symptoms typically develop in the 20s and 30s and may include difficulty running or walking, tripping, weakness in the index finger, and frequent loss of balance. Inclusion body myopathy 2 is caused by mutations in the GNE gene. The condition is inherited in an autosomal recessive manner. Treatment is focused on managing individual symptoms. </s></s>

<s>[INST] What are the symptoms of Inclusion body myopathy 2 ? [/INST] What are the signs and symptoms of Inclusion body myopathy 2? Inclusion body myopathy 2 causes muscle weakness that appears in late adolescence or early adulthood and worsens over time.The first sign of inclusion body myopathy 2 is often weakness of the tibialis anterior, a muscle in the lower leg that helps control up-and-down movement of the foot. Weakness in the tibialis anterior alters the way a person walks and makes it difficult to run and climb stairs. As the disorder progresses, weakness also develops in muscles of the upper legs, hips, shoulders, and hands. Unlike most forms of myopathy, inclusion body myopathy 2 usually does not affect the quadriceps (a group of large muscles at the front of the thigh). This condition also spares muscles of the eye or heart, and does not cause neurological problems. Weakness in leg muscles makes walking increasingly difficult, and most people with inclusion body myopathy 2 require wheelchair assistance within 20 years after signs and symptoms appear.

<s>[INST] What causes Inclusion body myopathy 2 ? [/INST] What causes inclusion body myopathy 2? Inclusion body myopathy 2 is caused by mutations in the GNE gene. The GNE gene provides instructions for making an enzyme responsible for making sialic acid, a simple sugar that attaches to the ends of more complex molecules on the surface of cells. People with inclusion body myopathy 2 have lower levels of sialic acid on the surface of certain proteins that are important for muscle function. This shortage of sialic acid leads to the progressive muscle wasting and disability seen in patients with inclusion body myopathy 2. Researchers are currently working towards a better understanding of how this shortage of sialic acid leads to the progressive muscle weakness in people with this condition. </s></s>

<s>[INST] What is (are) Pars planitis ? [/INST] Pars planitis is a disease of the eye that is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop. Pars planitis most often affects young men and is generally not associated with any other disease or symptoms (idiopathic); however, it can be associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Treatment typically includes corticosteroid drugs, immunosuppressive medications, and/or surgery. </s></s>

Pars planitis is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. Approximately 80% of cases are bilateral (affecting both eyes), although one eye is typically more affected than the other. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop. </s></s>

<s>[INST] What causes Pars planitis ? [/INST] What causes pars planitis? The exact underlying cause of pars planitis is unknown. Scientists suspect that it is an autoimmune condition in which the body's immune system mistakenly attacks healthy tissues (certain parts of the eyes, in this case). This is further supported by the fact that pars planitis is sometimes associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Although most cases occur sporadically in people with no family history of the condition, pars planitis can rarely affect more than one family member. In these cases, there may be a genetic component; however, a disease-causing gene and specific inheritance pattern have not been identified. </s></s>

<s>[INST] How to diagnose Pars planitis ? [/INST] How is pars planitis diagnosed? Pars planitis is typically diagnosed based on a specialized eye examination. During the exam, the ophthalmologist will typically see clusters of white blood cells trapped within the eyeball that are called snowballs (or "inflammatory exudate"). If these clusters are located on the pars plana, they are known as snowbanks. Snowbanks are considered a "hallmark" sign of pars planitis. It is often recommended that people over age 25 with pars planitis have an MRI of their brain and spine to rule out multiple sclerosis. </s></s>

<s>[INST] What are the treatments for Pars planitis ? [/INST] How might pars planitis be treated? The first approach to treating pars planitis is corticosteroid eye drops or injections near the eye to control inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs, including aspirin) or steroid medications (such as prednisone) can be taken by mouth. If these strategies are not successful, other medications may be given to reduce the body's immune response (medications called immunosuppressants, such as methotrexate). If medications are not effective, surgery may be considered. Cryotherapy has been performed in affected people to remove eye tissue that has inflammation. Although this surgery has been shown to be effective in restoring clarity of vision, there are concerns that it may cause damage to other parts of the eye. Another surgery, known as vitrectomy, can be done to remove cloudy fluid (vitreous humor) from the eye. </s></s>

<s>[INST] What is (are) Myelomeningocele ? [/INST] Myelomeningocele is the most severe form of spina bifida. It happens when parts of the spinal cord and nerves come through the open part of the spine. It causes nerve damage and other disabilities. Seventy to ninety percent of children with this condition also have too much fluid on their brains (hydrocephalus). This happens because fluid that protects the brain and spinal cord is unable to drain like it should. The fluid builds up, causing pressure and swelling. Without treatment, a persons head grows too big, and they may have brain damage. Other disorders of the spinal cord may be seen, including syringomyelia and hip dislocation. The cause of myelomeningocele is unknown. However, low levels of folic acid in a woman's body before and during early pregnancy is thought to play a part in this type of birth defect. </s></s>
