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.
Question:  What is (are) Chronic active Epstein-Barr virus infection ?
Answer: Chronic active Epstein-Barr virus infection is a rare condition in which the body makes too many lymphocytes, a type of white blood cell. Lymphocytes are an important part of the immune system because they help fight off diseases and protect the body from infection. About 95% of adults are infected with Epstein-Barr virus (EBV). Most infections occur during childhood and do not cause any symptoms. EBV infection in adolescents or young adults can often result in infectious mononucleosis.  Rarely, people infected with EBV develop a life-threatening condition called chronic active EBV virus (CAEBV). Patients with CAEBV most often have fever, liver dysfunction, an enlarged spleen (splenomegaly), swollen lymph nodes (lymphadenopathy), and low numbers of platelets (thrombocytopenia). Hematopoietic stem cell transplantation has shown promise in the treatment of CAEBV.

Question:  What is (are) Idiopathic juxtafoveal retinal telangiectasia ?
Answer: Idiopathic juxtafoveal retinal telangiectasia (IJT) refers to a group of eye conditions characterized by dilated or twisting blood vessels (telangiectasia) and defective capillaries (tiny blood vessels) near the fovea in the retina. The fovea has the biggest number of special retinal nerve cells, called cones, which enable sharp, daytime vision. In IJT, the telangiectasias cause fluid or crystal buildup and swelling, impairing reflection of light. This results in progressive vision loss. It may be congenital (present at birth) or can develop during the lifetime (acquired). The different types of IJT are distinguished by their features and treatment options. Laser photocoagulation maybe helpful in treating vision loss for individuals with certain types of IJT.
Question:  What are the symptoms of Idiopathic juxtafoveal retinal telangiectasia ?
Answer: What are the signs and symptoms of idiopathic juxtafoveal retinal telangiectasia? Signs and symptoms of idiopathic juxtafoveal retinal telangiectasia may include slow loss of vision, distorted vision, trouble reading, and scotomata (a spot in the visual field in which vision is absent or deficient).
Question:  What causes Idiopathic juxtafoveal retinal telangiectasia ?
Answer: What causes idiopathic juxtafoveal retinal telangiectasia? The exact, underlying cause of idiopathic juxtafoveal retinal telangiectasia (IJT) is not known. IJT has been reported in some siblings (including twins) and other family members of affected people. This suggests there may be a genetic component to IJT; however, no specific gene has been proven to cause the condition. Researchers have considered that changes in the ATM gene may interact with other genes or environmental factors to predispose a person to developing IJT. Some researchers have speculated that diabetes, or pre-diabetes, may be associated with some cases of IJT. However, to our knowledge, this association has not been proven. Others have suggested there may be a developmental cause, such as abnormal formation of vessels in the eye, which could cause abnormalities of the vessels in adulthood. Certain types of IJT may occur in association with other conditions, including polycythemia (abnormal increase in blood volume), hypoglycemia, ulcerative colitis, multiple myeloma and chronic lymphatic leukemia.
Question:  What are the treatments for Idiopathic juxtafoveal retinal telangiectasia ?
Answer: How might idiopathic juxtafoveal retinal telangiectasia (IJT) be treated? Laser photocoagulation of areas of leakage may be helpful in treating vision loss in people with certain subtypes of IJT, such as Group 1A. A laser is a powerful beam of light which can be focused on the retina. Small "bursts" of the laser can be used to seal leaky blood vessels, destroy abnormal blood vessels, seal retinal tears, and destroy abnormal tissue in the back of the eye. Photocoagulation usually is not considered for people with people in Group 1B because of the closeness of the leakage to the fovea, and the good prognosis without treatment. It may benefit people in Group 2 but in most cases, the abnormal lesions are so close to the fovea that treatment is difficult.
Question:  What is (are) Osteogenesis imperfecta ?
Answer: Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones. People with this condition have bones that break easily, often from little or no trauma. Severity varies among affected people. Multiple fractures are common, and in severe cases, can even occur before birth. Milder cases may involve only a few fractures over a person's lifetime. People with OI also have dental problems (dentinogenesis imperfecta) and hearing loss in adulthood. Other features may include muscle weakness, loose joints, and skeletal malformations. There are various recognized forms of OI which are distinguished by their features and genetic causes. Depending on the genetic cause, OI may be inherited in an autosomal dominant (more commonly) or autosomal recessive manner. Treatment is supportive and aims to decrease the number of fractures and disabilities.

Question:  What causes Osteogenesis imperfecta ?
Answer: What causes osteogenesis imperfecta? Osteogenesis imperfecta (OI) may be caused by changes (mutations) in any of several genes. OI is most commonly due to a mutation in either the COL1A1 or COL1A2 gene, causing OI types I through IV. These genes play a role in how the body makes collagen, a material that helps to strengthen the bones. The type and severity of OI depends on the effect that the specific mutation has on normal collagen production. OI caused by mutations in these genes is inherited in an autosomal dominant manner. In about 10% of people with OI, the COL1A1 and COL1A2 genes are normal and the condition is due to mutations in other genes; many of these people have an autosomal recessive form of OI. Other genes in which mutations may be responsible for less common types of OI, some of which have been reported in only one individual or family, include: IFITM5 (type V) SERPINF1 (type VI) CRTAP (type VII) LEPRE1, also called P3H1 (type VIII) PPIB (type IX) SERPINH1 (type X) FKBP10 (type XI) SP7 (type XII) BMP1 (type XIII) TMEM38B (type XIV) WNT1 (type XV) SPARC (type XVII)
Question:  Is Osteogenesis imperfecta inherited ?
Answer: How is osteogenesis imperfecta inherited? Osteogenesis imperfecta (OI) is most commonly inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause features of OI. The mutated copy of the gene may be inherited from an affected parent, or it may occur for the first time in an affected person (a de novo mutation). When a person with an autosomal dominant form of OI has children, each child has a 50% (1 in 2) chance of inheriting the mutated gene. If the child inherits the mutated gene, the child's symptoms may be milder, or more severe, than those of the parent. Less commonly, OI is inherited in an autosomal recessive manner. This means that both copies of the responsible gene in each cell must have a mutation for a person to be affected. The parents of a person with an autosomal recessive condition typically are unaffected, but each carry one mutated copy of the gene. When two carriers of an autosomal recessive form of OI have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to be unaffected and not be a carrier.
Question:  How to diagnose Osteogenesis imperfecta ?
Answer: Is genetic testing available for osteogenesis imperfecta? Genetic testing is available for individuals with osteogenesis imperfecta. The rate for detecting mutations in the genes that are responsible for OI varies depending on the type. Carrier testing may be available to relatives of affected individuals if the type of OI, disease-causing gene, and specific mutation in the affected individual are known. Prenatal testing for at-risk pregnancies can be performed by analysis of collagen made by fetal cells obtained by chorionic villus sampling (CVS) at about ten to 12 weeks' gestation if an abnormality of collagen has been identified in cells from the affected individual. Analysis of collagen after an amniocentesis (usually performed at 15-20 weeks gestation) is not useful, because the cells obtained do not produce type I collagen. However, prenatal testing can be performed by analyzing the genes (molecular genetic testing) if the specific mutation has been identified in the affected relative. GeneTests lists the names of laboratories that are performing genetic testing for different types of osteogenesis imperfecta. To view the contact information for the clinical laboratories conducting testing, click here and click on "Testing" next to the type of OI in which you are interested. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or genetics professional. Genetics professionals, such as genetic counselors, can also explain the inheritance of OI in detail including information about genetic risks to specific family members.

Question:  What is (are) Menetrier disease ?
Answer: Mntrier disease is a condition characterized by inflammation and ulcers of the mucosa (inner lining) of the stomach and by overgrowth of the cells that make up the mucosa. The condition is associated with the following signs: protein loss from the stomach, excessive mucus production, and hypochlorhydria (low levels of stomach acid) or achlorhydia (absent levels of stomach acid).   Symptoms usually include vomiting, diarrhea, and weight loss. The disease may increase an individual's risk of developing stomach cancer.

Question:  What causes Menetrier disease ?
Answer: What causes Mntrier disease? The exact cause of Mntrier disease is unknown.  However, it has been associated with cytomegalovirus (CMV) infection in children and Heliobacter pylori (H. pylori) infection in adults. In addition, some have suggested that overexpression of a type of growth factor called the transforming growth factor-, which is found in a specific part of the stomach, the superficial gastric epithelium, might play a role.
Question:  What are the treatments for Menetrier disease ?
Answer: What treatment is available for Mntrier disease? No one treatment has proven effective for all patients with Mntrier disease; however, some benefit has been shown through the use of anticholinergic drugs, acid suppression, octreotide, and H. pylori eradication. Partial or complete removal of the stomach is generally recommended for those patients who continue to have protein loss or who have signs of pre-cancer or cancer.
