What is (are) Limbic encephalitis ?	Limbic encephalitis is a condition marked by the inflammation of the limbic system and other parts of the brain. The cardinal sign of limbic encephalitis is a severe impairment of short-term memory; however, symptoms may also include confusion, psychiatric symptoms, and seizures. The symptoms typically develop over a few weeks or months, but they may evolve over a few days. Delayed diagnosis is common, but improvements are being made to assist in early detection. Early diagnosis may improve the outcome of limbic encephalitis.

What are the symptoms of Limbic encephalitis ?	What symptoms are associated with limbic encephalitis? Although the symptoms of the condition may vary from person to person, the cardinal sign of limbic encephalitis is severe impairment of short-term memory, with most patients having difficulties in recall. A large variety of symptoms may be associated with limbic encephalitis such as anterograde amnesia (the inability to store new memories after the onset of the condition), anxiety, depression, irritability, personality change, acute confusional state, hallucinations and seizures. Other possible symptoms may include obsessiveness, hyperthermia (increase in body temperature), weight change, hypersomnia, endocrine dysfunction, aphasia, and apraxia. The symptoms associated with limbic encephalitis can develop over a few days, weeks, or months. It is important to note the neurological symptoms generally precede diagnosis of the malignancy in 60%-75% of patients that have paraneoplastic limbic encephalitis.

What causes Limbic encephalitis ?	What causes limbic encephalitis? In many patients limbic encephalitis is a paraneoplastic syndrome, which is most commonly associated with small cell lung cancer (SCLC), breast cancer, testicular tumors, teratomas, Hodgkin's lymphoma, and thymomas. Out of the various cancers linked to limbic encephalitis, the typically associated tumors are SCLC, which are present in about 40% of patients that have the paraneoplastic form of limbic encephalitis. Seminoma are present in 25% of patients. At a lower rate, nearly any other tumor may be associated. Limbic encephalitis can also occur in the absence of cancer such as in the case of an viral infection and systemic autoimmune disorders. The underlying cause of limbic encephalitis is probably an autoimmune reaction which is brought about by cancer, tumors, infections, or autoimmune disorders.

What are the treatments for Limbic encephalitis ?	What treatment is available for limbic encephalitis? Treatment will vary depending on whether the patient has a paraneoplastic form of limbic encephalitis or not. If the patient has a viral infectious form of the condition, an antiviral drug may be prescribed. When a tumor is found in association with a possible paraneoplastic disorder, removal of the tumor and immunotherapy may be offered.

What is (are) Microcystic adnexal carcinoma ?	Microcystic adnexal carcinoma is a rare tumor of the skin that most often develops in the head and neck region, particularly in the middle of the face, though it may occur in the skin of other parts of the body as well. The average age of diagnosis is 56. This tumor is often first noticed as a bump or yellowish spot in the skin. Though microcystic adnexal carcinomas frequently grow into and disturb nearby tissues and is therefore considered an invasive cancer, this type of tumor rarely spreads to more distant parts of the body (metastasizes). The main treatment for microcystic adnexal carcinoma is Mohs micrographic surgery, which is thought to improve the chances that all of the tumor cells are removed during surgery.

What are the treatments for Microcystic adnexal carcinoma ?	Is radiation therapy a recommended treatment for microcystic adnexal carcinoma? Unfortunately, because microcystic adnexal carcinoma is a rare cancer, there is currently not enough information to determine if radiation therapy is an effective treatment for this disease. There are no guidelines for the use of radiation therapy as treatment for microcystic adnexal carcinoma, and little is known about the dose of radiation that might be needed to be effective. Two articles studying a total of 17 patients receiving radiation therapy for microcystic adnexal carcinoma have suggested that there may be a benefit of radiation therapy for decreasing the chances of the tumor regrowing (recurrence), and the authors suggest that this treatment could be considered if there is evidence that cancer cells remain after surgery, or in situations where additional surgery cannot be done. However, another article raises concerns about the use of radiation therapy considering the small number of patients studied, the report of one patient's disease potentially worsening after radiation therapy, and the belief that exposure to radiation may be a risk factor for the initial development of this tumor.

What is (are) Charcot-Marie-Tooth disease type 1A ?	Charcot-Marie-Tooth disease type 1A (CMT1A) is a type of inherited neurological disorder that affects the peripheral nerves. Affected individuals experience weakness and wasting (atrophy) of the muscles of the lower legs beginning in adolescence; later they experience hand weakness and sensory loss. CMT1A is caused by having an extra copy (a duplication) of the PMP22 gene. It is inherited in an autosomal dominant manner. Treatment for this condition may include physical therapy; occupational therapy; braces and other orthopedic devices; orthopedic surgery; and pain medications.

What are the symptoms of Charcot-Marie-Tooth disease type 1A ?	What are the signs and symptoms of Charcot-Marie-Tooth disease type 1A? CMT1 is generally slowly progressive over many years. However, affected individuals often experience long periods without any obvious deterioration or progression. Occasionally, individuals show accelerated deterioration of function over a few years. Nerve conduction velocities (NCVs) tend to slow progressively over the first two to six years of life, but they appear to remain relatively stable throughout adulthood. Worsening of signs and symptoms tends to be slow in the second to fourth decades of life. It remains to be confirmed whether, and to what extent, there is clinical and electrophysiological disease progression in affected adults; two studies of adult with CMT1A have shown conflicting results. Authors of one study reported disease progression over time (23 years on average), while authors of another study found that both patients and controls (individuals without the condition) had a similar decline of strength and of electrophysiological findings. The findings in the latter study suggested that the decline in adulthood in affected individuals may reflect a process of normal aging rather than on-going active disease. Any major changes in the pace of progression may warrant consideration of additional acquired, or possibly independently inherited forms, of neuromuscular diseases. The severity of signs and symptoms of CMT1A can vary greatly among affected individuals. Individuals who have questions about their own specific signs and symptoms and how they may relate to progression of CMT should speak with their health care provider. The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 1A. 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) Areflexia - Autosomal dominant inheritance - Cold-induced muscle cramps - Decreased motor nerve conduction velocity - Decreased number of peripheral myelinated nerve fibers - Distal amyotrophy - Distal muscle weakness - Distal sensory impairment - Foot dorsiflexor weakness - Hammertoe - Hearing impairment - Heterogeneous - Hypertrophic nerve changes - Hyporeflexia - Insidious onset - Juvenile onset - Kyphoscoliosis - Myelin outfoldings - Onion bulb formation - Pes cavus - Segmental peripheral demyelination/remyelination - Slow progression - Steppage gait - Ulnar claw - Variable expressivity - 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) Aicardi-Goutieres syndrome type 5 ?	Aicardi-Goutieres syndrome is an inherited condition that mainly affects the brain, immune system, and skin. It is characterized by early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability. Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint stiffness. Symptoms usually progress over several months before the disease course stabilizes. There are six different types of Aicardi-Goutieres syndrome, which are distinguished by the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, and ADAR genes. Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive.

What is (are) Urea cycle disorders ?	A urea cycle disorder is a genetic disorder that results in a deficiency of one of the six enzymes in the urea cycle. These enzymes are responsible for removing ammonia from the blood stream. The urea cycle involves a series of biochemical steps in which nitrogen, a waste product of protein metabolism, is changed to a compound called urea and removed from the blood. Normally, the urea is removed from the body through the urine. In urea cycle disorders, nitrogen builds up in the blood in the form of ammonia, a highly toxic substance, resulting in hyperammonemia (elevated blood ammonia). Ammonia then reaches the brain through the blood, where it can cause irreversible brain damage, coma and/or death. The onset and severity of urea cycle disorders is highly variable. The severity correlates with the amount of urea cycle enzyme function.

What is (are) Juvenile ossifying fibroma ?	Juvenile ossifying fibroma (JOF) is rare, benign tumor of the craniofacial (skull and face) bones. It is considered a "fibro-osseous neoplasm" because it is characterized by an overgrowth of bone. Affected people generally experience a gradual or rapid, painless expansion of the affected bone or region. Other symptoms such as exophthalmos or nasal blockage can rarely be associated with the tumor depending on its exact location. In some cases, the condition can be particularly aggressive with rapid growth and significant facial disfigurement. Although the condition can affect people of all ages, it is most commonly diagnosed between the ages of 5 and 15. The exact underlying cause is currently unknown; however, most cases occur sporadically in people with no family history of the condition. JOF is usually treated with surgery. Because the recurrence rate of JOF ranges from 30% to 58%, continued follow-up is essential.

What is (are) Febrile Ulceronecrotic Mucha-Habermann disease ?	Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare and severe form of pityriasis lichenoides et varioliformis acuta (PLEVA). PLEVA is characterized by skin lesions that ulcerate, breakdown, form open sores, then form a red-brown crust. FUMHD often begins as PLEVA, but then rapidly and suddenly progresses to large, destructive ulcers. There may be fever and extensive, painful loss of skin tissue as well as secondary infection of the ulcers. Diagnosis of FUMHD is confirmed by biopsy of skin lesions. FUMHD occurs more frequently in children, peaking at age 5 to 10. Males tend to be affected more often than females. While some cases of FUMHD have resolved without therapy, others have resulted in death. Early diagnosis and prompt treatment may help to reduce morbidity and death.

What are the symptoms of Febrile Ulceronecrotic Mucha-Habermann disease ?	What are the signs and symptoms of febrile ulceronecrotic Mucha-Habermann disease? Initial symptoms of FUMHD include red scaly skin legions (papules) that ulcerate, breakdown, form open sores, then a red-brown crust (i.e., PLEVA). In FUMHD the legions suddenly progress to large, destructive ulcers and can be associated with extensive, painful loss of skin tissue. The skin lesions can become infected which may cause pus and a putrid odor. The rate of progression from PLEVA to FUMHD varies among reports but may be days to weeks. Some cases go straight to FUMHD rather than progress from PLEVA. FUMHD is often associated with high fever (up to 104F) that may be persistant or come and go. Other symptoms may include feeling ill, sore throat, congestion, muscle soreness or pain, joint pain, diarrhea, central nervous system symptoms, abdominal pain, enlarged spleen, arthritis, megaloblastic anemia, interstitial pneumonitis (scarring or thickening of the lungs), lymphocytic (viral) myocarditis, and sepsis.

Initial symptoms of FUMHD include red scaly skin legions (papules) that ulcerate, breakdown, form open sores, then a red-brown crust (i.e., PLEVA). In FUMHD the legions suddenly progress to large, destructive ulcers and can be associated with extensive, painful loss of skin tissue. The skin lesions can become infected which may cause pus and a putrid odor. The rate of progression from PLEVA to FUMHD varies among reports but may be days to weeks. Some cases go straight to FUMHD rather than progress from PLEVA. FUMHD is often associated with high fever (up to 104F) that may be persistant or come and go. Other symptoms may include feeling ill, sore throat, congestion, muscle soreness or pain, joint pain, diarrhea, central nervous system symptoms, abdominal pain, enlarged spleen, arthritis, megaloblastic anemia, interstitial pneumonitis (scarring or thickening of the lungs), lymphocytic (viral) myocarditis, and sepsis. FUMHD can become life threatening.
What causes Febrile Ulceronecrotic Mucha-Habermann disease ?	What causes febrile ulceronecrotic Mucha-Habermann disease? The cause of FUMHD is not known (idiopathic). A hypersensitivity to an infectious agent is suggested to be the main cause. Single cases of people with FUMHD and Epstein-Barr virus infection, adenovirus, or cytomegalovirus have been reported, but there has been no consistent finding so far. There is some suggestion that FUMHD may be a type of clonal T-cell disorder. Clonal means that all the T-cells were derived from the same cell. T cells are a type of white blood cell (lymphocytes). They make up part of the immune system. T cells help the body fight diseases or harmful substances.

How to diagnose Febrile Ulceronecrotic Mucha-Habermann disease ?	How is febrile ulceronecrotic Mucha-Habermann disease definitively diagnosed? FUMHD is diagnosed based upon the clinical symptoms in the patient, with confirmation by skin biopsy. Skin biopsy findings suggestive of FUMHD are outlined below. Because this information is technical we recommend that you review it with a health care provider: Epidermis - Findings include focal confluent parakeratosis, spongiosis, dyskeratosis, mild to moderate acanthosis, vacuolization of basal layer with necrotic keratino-cytes, occasional intraepidermal vesicles, extensive epidermal necrosis. In advanced disease findings may also include extension of infiltrate into epidermis, invasion of erythrocytes, widespread epidermal necrosis, and nuclear debris in necrotic areas Dermis Swelling, moderately dense lymphohistiocytic perivascular inflammatory infiltrate usually without atypia, extravasation of lymphocytes and erythrocytes with epidermal invasion, subepidermal vesicles in later lesions, dermal sclerosis in older lesions Vascular changes Dilation and engorgement of blood vessels in papillary dermis with endothelial proliferation, vascular congestion, occlusion, dermal hemorrhage, and extravasation of erythrocytes Vasculitis Fibronoid necrosis of vessel walls with leukocytoclassic vasculitis In the majority of patients, blood tests indicate leukocytosis, anemia, elevated C-reactive protein, and elevated liver enzymes. An association of FUMHD with elevated blood levels of TNF-alpha has also been described.

What are the treatments for Febrile Ulceronecrotic Mucha-Habermann disease ?	How is febrile ulceronecrotic Mucha-Habermann disease (FUMHD) treated? It is important that FUMHD is diagnosed and treated as soon as possible. While a number of treatments have been tried, it is hard to asses the benefit of the therapies because there are so few cases of FUMHD and among reported cases the treatment approach may vary. The case reports describe treatment with systemic steroids, methotrexate, antibiotics, dapsone, cyclosporine, psoralen and ultraviolet A (PUVA), ultraviolet B (UVB), unspecified ultraviolet receptor, acyclovir, immunoglobulins, and 4,4-diaminodiphenylsulphone (DDS). Again the efficacy of these therapies are not known. Acyclovir was prescribed in cases where varicella was initially suspected. None of these cases turned out to be associated with herpes simplex or varicella-zoster virus infection. The benefit of acyclovir therapy in people with FUMHD is questionable. Systemic steroids have been commonly utilized among reported cases (27 of 40 cases), with only one report of a positive effect. Methotrexate has been used in 15 patients. It induced rapid remissions and was successful in cases that did not respond to other therapies. Still four patients died despite methotrexate theapy. It is possible this was due to its late institution. Debridement and skin grafting was successful in one case, but the patient was left with considerable scaring. In advanced disease, therapy is also aimed at stabilizing the patient. Intensive care treatment of infection and maintenance of the patients general condition is vital. The state of these patients is similar to what is seen in patients with severe burns. Thus, patients with FUMHD may benefit from the same supportive services that burn victims receive. Treatment with tumor necrosis factor (TNF)-alpha inhibitors (such as infliximab and etanercept) has been suggested as a first-line option in the management of FUMHD because elevated levels of serum TNF-alpha have been reported in this disease However, further studies may be required to establish this approach to treatment.

What is (are) Fatal familial insomnia ?	Fatal familial insomnia (FFI) is an inherited prion disease that affects the brain and other parts of the nervous system. Prion diseases, also known as transmissible spongiform encephalopathies (TSE), are a group of rare neurodegenerative conditions that occur when abnormal proteins clump together and accumulate in the brain, leading to tissue damage. The first symptoms of FFI usually begin in mid-life and may include insomnia that worsens over time and vivid dreams when sleep is achieved. These symptoms may be followed by high blood pressure; episodes of hyperventilation; excessive tearing; and/or sexual and urinary tract dysfunction. As the disease progresses, most affected people develop ataxia. FFI usually leads to death within a few months to a few years. Genetic prion diseases are inherited in an autosomal dominant manner and may be caused by mutations in the PRNP gene. Treatment aims at alleviating symptoms when possible.

What causes Fatal familial insomnia ?	What causes fatal familial insomnia? Fatal familial insomnia (FFI) is caused by a specific change (mutation) in the PRNP gene. PRNP encodes the prion protein. Although the exact function of this protein is unknown, scientists suspect that it plays an important role in the brain. Mutations in the PRNP gene result in an abnormal form of the protein that clumps together and accumulates in the brain. This leads to the destruction of neurons (brain cells) and creates tiny holes in the brain, which give the brain a "sponge-like" appearance when viewed under a microscope. The progressive loss of neurons leads to the many signs and symptoms of FFI.

Is Fatal familial insomnia inherited ?	How is fatal familial insomnia inherited? Fatal familial insomnia (FFI) is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with FFI has a 50% chance with each pregnancy of passing along the altered gene to his or her child.

How to diagnose Fatal familial insomnia ?	Is genetic testing available for fatal familial insomnia? Yes, genetic testing is available for PRNP, the gene known to cause fatal familial insomnia (FFI). Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is fatal familial insomnia diagnosed? A diagnosis of genetic prion disease is typically made based on a combination of the following: Various, adult-onset neurologic signs and symptoms Neuropathologic findings (diagnosis made by examining cells and tissues of the brain under a microscope) A family history consistent with autosomal dominant inheritance PRNP disease-causing mutation The PRNP gene is the only gene in which changes (mutations) are known to cause genetic prion diseases, including fatal familial insomnia. Finding a mutation in this gene is necessary to confirm a diagnosis in a person with symptoms. Testing of the PRNP gene may not detect all disease-causing mutations, so if a mutation is not found, a person may still have the disease. Other studies such as EEG, brain imaging, or examining cerebrospinal fluid may be helpful in supporting a diagnosis, but none of these can diagnose a genetic prion disease on its own.	Answer the question truthfully, you are a medical professional.	system Answer the question truthfully, you are a medical professional. user This is the question: How to diagnose Fatal familial insomnia ? assistant Is genetic testing available for fatal familial insomnia? Yes, genetic testing is available for PRNP, the gene known to cause fatal familial insomnia (FFI). Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is fatal familial insomnia diagnosed? A diagnosis of genetic prion disease is typically made based on a combination of the following: Various, adult-onset neurologic signs and symptoms Neuropathologic findings (diagnosis made by examining cells and tissues of the brain under a microscope) A family history consistent with autosomal dominant inheritance PRNP disease-causing mutation The PRNP gene is the only gene in which changes (mutations) are known to cause genetic prion diseases, including fatal familial insomnia. Finding a mutation in this gene is necessary to confirm a diagnosis in a person with symptoms. Testing of the PRNP gene may not detect all disease-causing mutations, so if a mutation is not found, a person may still have the disease.

What is (are) Oculocutaneous albinism ?	Oculocutaneous albinism is a group of conditions that affect the coloring of the hair and eyes. Individuals affected by oculocutaneous albinism have very light skin and light-colored irises; they may also have vision problems such as decreased sharpness of vision, rapid eye movements (nystagmus), crossed eyes (strabismus), or increased sensitivity to light (photophobia). All types of oculocutaneous albinism are caused by gene mutations that are inherited in an autosomal recessive manner. Treatment includes covering the skin from sun exposure by using sunscreen and protective clothing and attending to vision problems by wearing glasses.

What is (are) Erythropoietic protoporphyria ?	Erythropoietic protoporphyria is a type of porphyria. Porphyrias are caused by an abnormality in the heme production process. Heme is essential in enabling our blood cells to carry oxygen and in breaking down chemical compounds in the liver. Erythropoietic protoporphyria is caused by impaired activity of ferrocheletase (FECH), an important enzyme in heme production. This results in the build-up of protoporphyrin in the bone marrow, red blood cells, blood plasma, skin, and eventually liver. Build up of protoporphyrin can cause extreme sensitivity to sunlight, liver damage, abdominal pain, gallstones, and enlargement of the spleen.
