Question:  What is (are) Chronic fatigue syndrome ?
Answer: Chronic fatigue syndrome, also known as systemic exertion intolerance disease, is a condition that causes extreme, long-lasting fatigue which can limit the ability to participate in ordinary, daily activities.  It generally occurs in young adults between the ages of 20 and 40 and is twice as common in women. The main symptom is disabling fatigue that does not improve with rest. Other signs and symptoms may include muscle pain; joint pain; concentration and memory problems; headaches; sleep problems; fever; sore throat; and/or tender lymph nodes. The cause of chronic fatigue syndrome is not known yet. Some researchers have proposed that this condition is caused by viral infections or by immunological, hormonal or mental or psychiatric problems, but none have been proved. It is also believed that there may be a genetic predisposition for this condition and stress-related events act as triggers. Because the symptoms are similar to many conditions that need to be ruled out, the diagnosis make take some time to be made and patients are frequently misunderstood. Those who are affected are typically highly functioning individuals who are "struck down" with this disease. There is still no cure for this condition but there are several clinical trials. Current treatment consists of cognitive and/or behavioral therapy and focuses on improving symptoms and may include medications to treat pain, sleep disorders and other associated problems. There is significant controversy and debate in the medical literature about the relationship between myalgic encephalomyelitis and chronic fatigue syndrome. Unfortunately there is no consensus on nomenclature or classification for these disorders, and different countries, organizations, and researchers continue to use different names to describe these conditions. Until a global consensus is reached on how to name and classify these disorders, confusion will persist.
Question:  How to diagnose Chronic fatigue syndrome ?
Answer: How is chronic fatigue syndrome diagnosed? No specific diagnostic tests are available. Though there is no definitive diagnostic test, the diagnosis can be made if the patient has a typical history, and no abnormality can be detected on the exam or in the screening tests.    The Committee on the Diagnostic Criteria for Myalgic Encephalomyelitis/Chronic Fatigue Syndrome, The Board of Select Populations and the Institute of Medicine proposed a diagnosis criteria which requires that the patient have the following three symptoms: 1. A chronic fatigue that interferes with the daily activities and work,  which is often profound, is of new or definite onset (not lifelong), is not the result of ongoing excessive exertion or other medical conditions, and is not greatly alleviated by rest. 2. Post-exertional malaise. 3. Unrefreshing sleep. At least one of the two following symptoms is also required: 1. Cognitive impairment (imparirment of short memory or concentration). 2. Orthostatic intolerance (Onset of symptoms when standing upright that are improved by lying back down). Other  symptoms include post exertion illness lasting more than 24 hours, muscle pain, pain in the joints, headaces, tender lymph nodes and sore throat.   These symptoms should have persisted or recurred during 6 or more consecutive months of illness and they cannot have first appeared before the fatigue. The following tests are expected to be normal in patients with chronic fatigue syndrome:  Complete blood count with differential count;  Chemistry screen;  Thyroid stimulating hormone level;  Other tests based in the patients symptoms like immunologic tests or serologic tests.
Question:  What are the treatments for Chronic fatigue syndrome ?
Answer: How might chronic fatigue syndrome be treated? Treatment options for chronic fatigue syndrome (CFS) are limited.[9440] Treatment is largely supportive and is focused on the specific symptoms present in each individual. In most cases, symptoms of CFS lessen over time. Many therapies have been tried, but only cognitive behavioral therapy (CBT) and graded exercise therapy reportedly appear to produce meaningful benefit. CBT typically involves a series of one-hour sessions designed to alter beliefs and behaviors that might delay recovery. Graded exercise therapy can be beneficial because prolonged lack of exercise may worsen the symptoms of the condition and should be discouraged.[9440] Gradual introduction of regular aerobic exercise, such as walking, swimming, cycling, or jogging, under close medical supervision may reduce fatigue and improve physical function. The goal is to have 30 minutes of light exercise five times a week. To avoid overexertion it is recommended to set a target heart rate range, generally <100 beats per minute. Graded exercise should be always supervised by a physical therapist or exercise therapist. In some studies, women with this condition were found to have low normal fitness on treadmill testing with no indication of heart or lung problems. Maximal testing did not result in worse fatigue or other symptoms. Because many people who have CFS are also depressed, treating the depression can make it easier to cope with the problems associated with CFS. Low doses of some antidepressants may help improve sleep and relieve pain.[6269] A number of medications, special diets and vitamin supplements have been evaluated in individuals with CFS, but none have been proven effective. Although there have been a number of viruses that were initially reported to cause CFS, additional studies have not proven this.[9440] Trials of antiviral agents have been ineffective in relieving the symptoms of CFS. Several clinical trials aiming to find effective treatment are currently ongoing.

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.
Question:  What is (are) Choroideremia ?
Answer: Choroideremia is a genetic condition that causes vision loss. This disorder typically affects males. The first symptom is usually impairment of night vision (night blindness), which can occur in childhood. People with this disorder also experience narrowing of the field of vision (tunnel vision) and decrease in the ability to see details (visual acuity). The vision problems are due to loss of cells in the retina (light sensitive part of the eye) and choroid (blood vessels in the eye). The vision issues tend to get worse over time and usually lead to blindness in late adulthood. The rate and degree of vision loss differs for each person. Choroideremia is caused by spelling mistakes (mutations) in the CHM gene and is inherited in an X-linked recessive pattern.

Question:  What is (are) Dystonia 8 ?
Answer: Paroxysmal nonkinesigenic dyskinesia is a disorder of the nervous system that causes periods of involuntary movement. Common symptoms include 1 to 4 hour long episodes of irregular, jerking or shaking movements, prolonged contraction of muscles, chorea, and/or writhing movements of the limb. The movements may have no known trigger or be brought on by alcohol, caffeine, stress, fatigue, menses, or excitement.  The familial form is caused by mutations in the PNKD gene and is inherited in an autosomal dominant pattern.

Question:  What causes Dystonia 8 ?
Answer: Are there non-genetic causes of paroxysmal nonkinesigenic dyskinesia? Yes. Sporadic (non-genetic) causes of paroxysmal nonkinesigenic dyskinesia have been reported in the literature. Non-genetic causes include lesions of the basal ganglia due to multiple sclerosis, tumors, and vascular lesions. In addition, lesions outside the basal ganglia (including those due to penetrating injury) have been reported as causing symptoms similar to those found in paroxysmal nonkinesigenic dyskinesia. In these situations, careful evaluation by a neurologist and neuroimaging (such as MRI) may be necessary for diagnosis.
Question:  What is (are) Thrombotic thrombocytopenic purpura, congenital ?
Answer: Thrombotic thrombocytopenic purpura (TTP), congenital is a blood disorder characterized by low platelets (i.e., thrombocytopenia), small areas of bleeding under the skin (i.e., purpura), low red blood cell count, and hemolytic anemia. TTP causes blood clots (thrombi) to form in small blood vessels throughout the body. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart. Resulting complications can include neurological problems (such as personality changes, headaches, confusion, and slurred speech), fever, abnormal kidney function, abdominal pain, and heart problems. Hemolytic anemia can lead to paleness, yellowing of the eyes and skin (jaundice), fatigue, shortness of breath, and a rapid heart rate. TTP, congenital is much rarer than the acquired form and typically appears in infancy or early childhood. Signs and symptoms often recur on a regular basis. TTP, congenital results from mutations in the ADAMTS13 gene. The condition is inherited in an autosomal recessive manner.

Question:  What is (are) Metachondromatosis ?
Answer: Metachondromatosis (MC) is a rare bone disorder characterized by the presence of both multiple enchondromas and osteochondroma-like lesions. The first signs occur during the first decade of life. Osteochondromas most commonly occur in the hands and feet (predominantly in digits and toes), and enchondromas involve the iliac crests and metaphyses of long bones. The lesions typically spontaneously decrease in size or regress. Nerve paralysis or vascular complications may occur in some cases. The condition has been linked to mutations in the PTPN11 gene in several families and is inherited in an autosomal dominant manner. Treatment may include surgery to remove osteochondromas in severe cases.[8171]
Question:  What causes Ewing's family of tumors ?
Answer: What causes Askins tumor? In 80% to 90% of Askins tumors, a part of chromosome 11 and chromosome 22 are translocated. 'Translocation' means that the chromosomes have exchanged material. This exchange of material interrupts the cell's ability to grow and divide normally. In general, cancers are caused when the genes that regulate the cell's growth and division are changed. The cause of the changes is unknown, but may be due to a combination of genetic factors, environmental factors, and the process of aging. The development of cancer is not a quick or simple process. It is a progression involving a build-up of changes in a number of different genes in the cells of the body tissues over time.
Question:  What is (are) Febrile Ulceronecrotic Mucha-Habermann disease ?
Answer: 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.
Question:  What are the symptoms of Febrile Ulceronecrotic Mucha-Habermann disease ?
Answer: 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. FUMHD can become life threatening.
Question:  What causes Febrile Ulceronecrotic Mucha-Habermann disease ?
Answer: 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.
