What causes Pigmented villonodular synovitis ? | What causes pigmented villonodular synovitis? The exact cause of pigmented villonodular synovitis (PVNS) is unknown. Some doctors believe that it is similar to arthritis, arising from swelling (inflammation) of the joint tissue. Others believe it develops like a tumor, caused by cells growing and multiplying more quickly than usual. The association between a history of trauma and the development of PVNS is unclear. One study found that 56% of individuals with PVNS had a history of previous trauma, while other studies have found a much lower incidence. There have been studies suggesting that PVNS could be caused by specific genetic changes in the cells lining the joint. More studies are needed to research this association. | |
How to diagnose Pigmented villonodular synovitis ? | How is pigmented villonodular synovitis diagnosed? Pigmented villonodular synovitis (PVNS) is diagnosed via physician examination, imaging studies, and sometimes surgical procedures. Imaging studies commonly used include: X-ray, MRI, and CT scan. MRI findings are diagnostic in more than 95% of patients. CT scan findings are additionally often diagnostic, though they might not show the extent of the disease. Other methods that might be utilized in the diagnostic process include joint aspiration, in which a needle is used to remove fluid from the joint and a biopsy, in which a small operation is completed to obtain a tissue sample. | |
What are the treatments for Pigmented villonodular synovitis ? | How might pigmented villonodular synovitis be treated? Pigmented villonodular synovitis is first treated with surgery to remove as much of the abnormal tissue growth as possible. The type of surgery depends on the location and extent of the disease within the joint. Radiation therapy is sometimes used to treat this condition if surgery is not an option, or if the condition returns (recurs) after an initial surgery. | |

What is (are) Porencephaly ? | Porencephaly is a rare condition that affects the central nervous system. People with porencephaly develop fluid-filled cysts or cavities in the brain either before or shortly after birth. The severity of the condition and the associated signs and symptoms vary significantly based on the size, location, and number of cysts. Common features include developmental delay, reduced muscle tone (hypotonia), seizures, macrocephaly (unusually large head size), spastic hemiplegia, speech problems, delayed growth, and intellectual disability. Porencephaly is usually the result of damage from infection or stroke after birth. In these cases, the condition occurs sporadically in people with no family history of the condition. There is an inherited form of the condition called familial porencephaly, which is caused by changes (mutations) in the COL4A1 or COL4A2 genes and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person and may include physical therapy and medication for seizures. | |

What is (are) Junctional epidermolysis bullosa ? | Junctional epidermolysis bullosa (JEB) is a type of Epidermolysis Bullosa, a group of genetic conditions that cause the skin to be very fragile and to blister easily. JEB is separated into two categories: the Herlitz type and the Non-Herlitz type. The Herlitz type of JEB is very severe, and individuals with this condition often do not survive infancy. The Non-Herlitz type includes several subtypes that cause mild to severe blistering of the skin present at birth or shortly thereafter. JEB is inherited in an autosomal recessive pattern. It is caused by mutations in the LAMB3, COL17A1, or LAMC2, and LAMA3 genes.There is no cure for JEB. Treatment is focused on management of blistering and prevention of secondary infections. | |

What is (are) Pseudopelade of Brocq ? | Pseudopelade of Brocq (PBB) is a slowly progressive, chronic condition characterized by scarring hair loss (cicatricial alopecia). There exists some controversy as to whether PBB is a distinct condition or the common final stage or variant of several different forms of scarring alopecias such as discoid lupus erythematosus (DLE) or lichen planopilaris (LPP). Some have suggested abandoning the use of the term pseudopelade of Brocq while others think that the term should be strictly used to describe patients that follow the pattern of hair loss described by Brocq et al.(i.e., multiple, small, discrete, asymmetrical, smooth, soft, flesh-colored or white patches of hair loss with little, if any, inflammation). Although the exact cause of PBB has not been identified, it is believed to be an autoimmune disease. Some individuals with PBB have been found to have Borrelia burgdorferi, the bacterium that causes Lyme disease. Neither an effective treatment nor cure is currently available. | |

What are the treatments for Pseudopelade of Brocq ? | Is there treatment or a cure for pseudopelade of Brocq? Neither an effective treatment nor cure has been identified for pseudopelade of Brocq. Unfortunately, even when treatment relieves the symptoms and signs, the progression of hair loss may continue. The choice of treatment prescribed varies from person to person and depends mainly on the activity, extent of the disease and patient's tolerance to the treatment. Various forms of corticosteroids have been tried, including injections or skin lotions or creams. Surgery such as hair transplant or scalp reduction might be considered in patients whose condition has remained stable for two or more years. | |

What is (are) Postural orthostatic tachycardia syndrome ? | Postural orthostatic tachycardia syndrome (POTS) is a rare condition that is primarily characterized by orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). Orthostatic Intolerance is generally associated with lightheadedness and/or fainting that is typically relieved by lying down again. In people with POTS, these symptoms are also accompanied by a rapid increase in heartbeat. Although POTS can affect men and women of all ages, most cases are diagnosed in women between the ages of 15 and 50. The exact underlying cause of POTS is currently unknown. However, episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period. Treatment aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition. | |

Orthostatic Intolerance is generally associated with lightheadedness and/or fainting that is typically relieved by lying down again. In people with POTS, these symptoms are also accompanied by a rapid increase in heartbeat. Other symptoms reported in POTS include: Visual changes (i.e. blurry vision) Throbbing of the head Poor concentration Tiredness Gastrointestinal symptoms (i.e. nausea, cramps, bloating, constipation, diarrhea) Shortness of breath Head, neck and/or chest discomfort Weakness Sleep disorders Exercise intolerance Sweating Anxiety | |
What causes Postural orthostatic tachycardia syndrome ? | What causes postural orthostatic tachycardia syndrome? The underlying cause of postural orthostatic tachycardia syndrome (POTS) is poorly understood. However, episodes often begin after a pregnancy, major surgery, trauma, or a viral illness and may increase right before a menstrual period. Many researchers suspect that there may be more than one cause for the condition. The following abnormalities can be associated with POTS and may play a role in the development of the condition: Peripheral denervation - reduced nerve stimulation to certain muscles. The lower extremities are generally most affected in people with POTS. Hypovolemia - an abnormal decrease or redistribution of blood in the body Changes in venous function - more specifically, a reduction in the volume of blood that returns to the heart (venous return) when moving from a lying down to a standing position Cardiovascular deconditioning - changes in cardiovascular function Baroreflex abnormalities - the baroreflexes play an important role in blood pressure regulation. When they sense a change in blood pressure, the heart rate is adjusted and the sympathetic nerve system fibers are activated to cause the blood vessels to narrow. Increased activity of the sympathetic nervous system Although most cases of POTS appear to occur sporadically in people with no family history of the condition, some affected people report a family history of orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). This suggests that genetic factors may play a role in the development of POTS in some cases. Some studies also suggest that polymorphisms in certain genes (NOS3, ADRB2) may be associated with an increased risk of developing the condition and a change (mutation) in the norepinephrine transporter gene (SLC6A2) has been identified in one family with POTS. | |
Is Postural orthostatic tachycardia syndrome inherited ? | Is postural orthostatic tachycardia syndrome inherited? Most cases of postural orthostatic tachycardia syndrome (POTS) are not thought to be inherited. Although the condition generally occurs sporadically, some people with POTS do report a family history of orthostatic intolerance (an excessively reduced volume of blood returns to the heart when moving from a lying down to a standing position). This suggests that inherited factors may play a role in the development of POTS in some families. | |
How to diagnose Postural orthostatic tachycardia syndrome ? | How is postural orthostatic tachycardia syndrome diagnosed? A diagnosis of postural orthostatic tachycardia syndrome (POTS) is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. Many physicians will conduct a physical examination, including measuring blood pressure and heart rate while lying, sitting, and standing. A tilt table test may also be recommended to help confirm the diagnosis. | |
What are the treatments for Postural orthostatic tachycardia syndrome ? | How is postural orthostatic tachycardia syndrome treated? Because postural orthostatic tachycardia syndrome (POTS) is thought to have a variety of causes, there is no single treatment that is effective for all people with the condition. In general, management of POTS aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition. In some affected people, simple life style interventions such as adding extra salt to the diet, ensuring adequate fluid intake, participating in a specialized exercise program, and avoiding factors that exacerbate the condition appear to improve symptoms. Certain medications have also been used to treat POTS with some success. | |
What is (are) Epidermolysis bullosa acquisita ? | Epidermolysis bullosa acquisita (EBA) is a rare autoimmune disorder that causes the skin to blister in response to minor injury. Common areas of blistering include the hands, feet, knees, elbows, and buttocks. It can also affect the mouth, nose, and eyes. Some affected people have other health problems such as Crohn's disease, systemic lupus erythematosus, amyloidosis, or multiple myeloma. EBA is not inherited and usually occurs in adulthood. Treatment aims to protect the skin, stop the formation of blisters, and promote healing. Immunosuppressive drugs may be used to reduce the body's autoimmune response. | |
What are the symptoms of Epidermolysis bullosa acquisita ? | What are the signs and symptoms of Epidermolysis bullosa acquisita? Symptoms of epidermolysis bullosa acquisita (EBA) usually occur in a person's 30s or 40s. The signs and symptoms can differ among affected people, and the condition has several distinct forms of onset. For example: Non-inflammatory or mildly inflammatory EBA affecting only trauma-prone skin (the "classic" form) may cause: tense, blood- or pus-filled blisters, mostly on the hands, knees, knuckles, elbows and ankles mucous-membrane blisters that rupture easily healing with significant scarring and small white spots (milia) Generalized inflammatory EBA may cause: widespread blisters that are not localized to trauma-prone sites generalized redness and itching healing with minimal scarring The mucous membrane form of EBA may cause: blisters on various mucous membranes significant scarring and dysfunction The features of the condition may change during the course of the disease or may represent two forms at the same time. The Human Phenotype Ontology provides the following list of signs and symptoms for Epidermolysis bullosa acquisita. If the information is available, the table below includes how often the symptom is seen in people with this condition.

What causes Epidermolysis bullosa acquisita ? | What causes epidermolysis bullosa acquisita? The underlying cause of epidermolysis bullosa acquisita (EBA) is not known. It is thought to be an autoimmune disorder, which means that the immune system attacks healthy cells by mistake. In EBA, certain immune proteins (usually IgG autoantibodies) mistakenly target and attack a specific type of collagen (a skin protein) involved in "anchoring" the skin. In some milder cases of EBA, the immune proteins involved are thought to be IgA, rather than IgG autoantibodies. The initiating event that leads to autoantibody production is unknown. EBA affecting several family members has been reported, suggesting a genetic component may be involved in some cases. Rarely, people with lupus, a systemic autoimmune disease, develop a generalized blistering skin disease with the features of EBA. EBA has also been associated with Crohn's disease. | |
Is Epidermolysis bullosa acquisita inherited ? | Is epidermolysis bullosa acquisita inherited? Unlike the genetic forms of epidermolysis bullosa, epidermolysis bullosa acquisita (EBA) is considered an acquired, sporadic disease. This means that it generally occurs in people with no history of the condition in their families. There have been a couple of reports of families with more than one affected person, suggesting a genetic component may be involved. This could mean that EBA may develop in a person who is "genetically susceptible." However, the condition is not thought to be due to any specific gene(s). | |

What is (are) Exogenous ochronosis ? | Exogenous ochronosis refers to the bluish-black discoloration of certain tissues, such as the ear cartilage, the ocular (eye) tissue, and other body locations when it is due to exposure to various substances. It has been reported most commonly with topical application of hydroquinones to the skin. The discoloration may be caused by an effect on tyrosinase (an enzyme located in melanocytes, which are skin cells that produce pigment), or by inhibiting homogentisic acid oxidase, resulting in the accumulation and deposition of homogentisic acid (HGA) in cartilage. The discoloration is often permanent, but when exogenous ochronosis is caused by topical hydroquinones, carbon dioxide lasers and dermabrasion have been reported to be helpful. Exogenous ochronosis is different from hereditary ochronosis, which is an inherited condition that occurs with alkaptonuria. | |

What is (are) Birdshot chorioretinopathy ? | Birdshot chorioretinopathy is an eye condition in which painless, light-colored spots develop on the retina. These spots are scattered in a "birdshot" pattern. The effects of this condition on vision are quite variable; some individuals' vision is only mildly affected, whereas others experience a significant decline in vision, the appearance of floaters (small specks that appear in one's line of sight), night blindness, and other vision problems. Symptoms typically begin around middle age; Caucasians are affected more than individuals of other ethnicities. The cause of birdshot chorioretinopathy is currently unknown, but it is suspected to be an autoimmune disease. Treatment may include medications that aim to regulate the body's immune response. | |

What is (are) LCHAD deficiency ? | LCHAD deficiency, or long-chain 3-hydroxyacyl-CoA dehydrogenase deficiency, is a mitochondrial condition that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Signs and symptoms typically appear during infancy or early childhood and can include feeding difficulties, lack of energy, low blood sugar (hypoglycemia), weak muscle tone (hypotonia), liver problems, and abnormalities in the retina. Later in childhood, people with this condition may experience muscle pain, breakdown of muscle tissue, and peripheral neuropathy. Individuals with LCHAD deficiency are also at risk for serious heart problems, breathing difficulties, coma, and sudden death. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the HADHA gene.[OMIM] | |

What is (are) Cushing disease ? | Cushing disease is a condition caused by elevated levels of a hormone called cortisol. It is part of a group of diseases known as Cushings syndrome. The signs and symptoms include weight gain around the trunk and in the face, stretch marks, easy bruising, a hump on the upper back, muscle weakness, tiredness, thin bones that are prone to fracture (osteoporosis), mood disorders and memory problems. Patients also have an increased risk of infections, high blood pressure and diabetes. Women may have irregular menses and a lot of hair in the body (hirsutism). Cushing disease occurs when a benign pituitary tumor (adenoma) or pituitary hyperplasia causes the adrenal glands to produce large amounts of cortisol. The genetic cause of Cushing disease is often unknown but some cases are caused by somatic mutations in genes involved in hormonal activity. Most cases occur sporadically in people with no family history of the condition. Rarely, Cushing disease can be inherited, either as an isolated condition or as part of a genetic syndrome (such as multiple endocrine neoplasia type 1 (MEN1) and familial isolated pituitary adenoma). Treatment generally involves surgery to remove the tumor and medications to decrease cortisol levels. | |

What is (are) Proteus syndrome ? | Proteus syndrome is characterized by excessive growth of a part or portion of the body. The overgrowth can cause differences in appearance and with time, an increased risk for blood clots and tumors. It is caused by a change (mutation) in the AKT1 gene. It is not inherited, but occurs as a random mutation in a body cell in a developing baby (fetus) early in pregnancy. The AKT1 gene mutation affects only a portion of the body cells. This is why only a portion of the body is affected and why individuals with Proteus syndrome can be very differently affected. Management of the condition often requires a team of specialists with knowledge of the wide array of features and complications of this condition. | |

What causes Proteus syndrome ? | What causes Proteus syndrome? Proteus syndrome is caused by mutations in the AKT1 gene. This genetic change is not inherited from a parent; it arises randomly in one cell during the early stages of development before birth. As cells continue to grow and divide, some cells will have the mutation and others will not. This mixture of cells with and without a genetic mutation is known as mosaicism. The AKT1 gene helps regulate cell growth and division. (proliferation) and cell death. A mutation in this gene disrupts a cell's ability to regulate its own growth, allowing it to grow and divide abnormally. Increased cell proliferation in various tissues and organs leads to the abnormal growth characteristics of Proteus syndrome. Studies suggest that AKT1 gene mutations are more common in groups of cells that experience overgrowth than in the parts of the body that grow normally. | |

Is Noonan syndrome inherited ? | How is Noonan syndrome inherited? Noonan syndrome is inherited in an autosomal dominant manner. This means that having one changed (mutated) copy of the responsible gene in each cell is enough to cause the condition. Each child of a person with Noonan syndrome has a 50% (1 in 2) chance to inherit the condition. In some cases, the condition is inherited from an affected parent. Because the features of the condition can vary and may be very subtle, many affected adults are diagnosed only after the birth of a more obviously affected infant. In other cases, the condition is caused by a new mutation occurring for the first time in the affected person. | |
What are the treatments for Noonan syndrome ? | How might Noonan syndrome be treated? Management generally focuses on the specific signs and symptoms present in each person. Treatments for the complications of Noonan syndrome (such as cardiovascular abnormalities) are generally standard and do not differ from treatment in the general population. Developmental disabilities are addressed by early intervention programs and individualized education strategies. Treatment for serious bleeding depends upon the specific factor deficiency or platelet abnormality. Growth hormone treatment increases growth velocity. More detailed information about treatment for Noonan syndrome can be viewed on the GeneReviews Web site. | |

What is (are) Singleton Merten syndrome ? | Singleton Merten syndrome is an extremely rare, multisystem disorder. The major characteristics are tooth abnormalities (dental dysplasia); calcifications in the aorta and certain valves of the heart (i.e., aortic and mitral valves); and progressive thinning and loss of protein of the bones (osteoporosis), especially the upper and back portions of the skull. Other physical findings may include generalized muscle weakness; progressive muscle atrophy; growth delay; delays in motor development; skin conditions; and/or malformation of the hips and/or feet. It appears to occur sporadically (in individuals with no history of the condition in their family) but in some cases, autosomal dominant inheritance has been suggested. Treatment is typically directed toward the specific symptoms that are present in each individual. | |
What are the symptoms of Singleton Merten syndrome ? | What are the signs and symptoms of Singleton Merten syndrome? Singleton Merten syndrome is characterized by abnormalities of the teeth (dental dysplasia); abnormal accumulation of calcium deposits (calcifications) in the aorta and certain valves of the heart (i.e., aortic and mitral valves); and/or progressive thinning and loss of protein of the bones (osteoporosis). Between the ages of four to 24 months, most affected infants experience generalized muscle weakness and loss or wasting away (atrophy) of muscle tissue. In approximately half of the reported cases, these symptoms begin after an episode of illness associated with a fever. Affected infants may also show delays in general physical development, possibly resulting in short stature or delays in the ability to coordinate muscles and perform certain tasks (motor development). Abnormalities affecting the teeth also occur at an early age in individuals with Singleton Merten syndrome. Affected infants may develop cavities and lose their primary teeth prematurely. Certain permanent teeth may not develop or may erupt late; those permanent teeth that do develop are usually malformed. In some cases, permanent teeth may also be lost prematurely. By late infancy or early childhood, affected individuals may experience symptoms associated with the progressive accumulation of calcium deposits (calcifications) in the aorta and on certain valves of the heart. The aorta arises from the lower pumping chamber of the heart (left ventricle) and supplies oxygen-rich blood to all the arteries of the body (excluding the pulmonary artery). In individuals with Singleton Merten Syndrome, calcifications form in the portion of the aorta nearest the heart (proximal thoracic aorta). The accumulation of calcium deposits is progressive and typically causes blockage and narrowing of the aorta (called calcific aortic stenosis), obstructing the flow of oxygenated blood. In some cases, abnormal calcium deposits may also develop around the valve on the left side of the heart (mitral valve calcification). As a result of calcification of these various structures, affected individuals may experience high blood pressure (hypertension); abnormal transmission of electrical impulses (conduction) that coordinate the activity of the heart muscle (heart block); abnormal contractions of the heart (systolic murmurs); and/or abnormal enlargement of the heart (cardiomegaly). By late adolescence, the heart may be unable to pump blood effectively, causing heart failure and leading to life-threatening complications. Infants with Singleton Merten syndrome may also experience abnormal thinning and weakness of the bones (osteoporosis). As a result, bones are frequently brittle and may fracture easily. Osteoporosis may occur in the skull and the long bones of the arms and legs, but is most prominent in the bones of the hands and fingers. Other findings associated with Singleton Merten syndrome may include malformations of the hips and feet that may occur due to muscle weakness; wearing away (erosion) of the bones in the tips of the fingers (terminal phalanges); and/or a chronic skin condition characterized by red, thick, scaly patches of skin (psoriasiform skin eruption). In some cases, affected individuals may have abnormal accumulation of pressure of the fluid of the eye (glaucoma) and/or abnormal sensitivity to light (photosensitivity). The Human Phenotype Ontology provides the following list of signs and symptoms for Singleton Merten syndrome. If the information is available, the table below includes how often the symptom is seen in people with this condition.

How to diagnose Singleton Merten syndrome ? | How is Singleton Merten syndrome diagnosed? The diagnosis of Singleton Merten syndrome may be suspected during infancy based upon the identification of characteristic physical findings (i.e., muscle weakness, muscle atrophy, dental abnormalities, and skeletal changes). A diagnosis may be confirmed by a thorough clinical evaluation, a detailed patient history, and/or a variety of specialized tests. The identification of calcium deposits in the aorta, in association with the other findings described above, strongly suggests a diagnosis of Singleton Merten syndrome. X-ray tests may be used to confirm the presence and extent of calcifications in the aorta. Obstruction or narrowing (stenosis) of the heart valves, particularly the aortic and mitral valves, may be confirmed by cardiac catheterization. During this procedure, a small hollow tube (catheter) is inserted into a large vein and threaded through the blood vessels leading to the heart. This procedure allows physicians to determine the rate of blood flow through the heart and measure the pressure within the heart. X-ray studies may also be performed to confirm the presence and extent of osteoporosis. Osteoporosis may be suspected when bone fractures occur more frequently than usual. X-ray tests may also reveal abnormal widening of the hollow parts of the bones that contain soft fatty tissue (bone marrow cavities) within the bones of the hands and/or feet. | |
What are the treatments for Singleton Merten syndrome ? | How might Singleton Merten syndrome be treated? The treatment of Singleton Merten syndrome is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. Pediatricians, surgeons, specialists who diagnose and treat abnormalities of the heart (cardiologists), dental specialists, physical therapists, specialists who diagnose and treat conditions of the skin (dermatologists), and other health care professionals may need to systematically and comprehensively plan an affected child's treatment. Specific therapies for the treatment of Singleton Merten syndrome are symptomatic and supportive. Special services that may be beneficial to affected children may include special social support, physical therapy, and other medical, social, and/or vocational services. Genetic counseling would be of benefit for affected individuals and their families. | |

What is (are) Pulmonary alveolar microlithiasis ? | Pulmonary alveolar microlithiasis is a disorder in which tiny fragments (microliths) of calcium phosphate gradually accumulate in the small air sacs (alveoli) of the lungs. These deposits eventually cause widespread damage to the alveoli and surrounding lung tissue (interstitial lung disease). People with this disorder may also develop a persistent cough and difficulty breathing (dyspnea), especially during physical exertion. Chest pain that worsens when coughing, sneezing, or taking deep breaths is another common feature. People with pulmonary alveolar microlithiasis may also develop calcium phosphate deposits in other organs and tissue of the body. Though the course of the disease can be variable, many cases slowly progress to lung fibrosis, respiratory failure, or cor pulmonale. The only effective therapy is lung transplantation. In some cases, pulmonary alveolar microlithiasis is caused by mutations in the SLC34A2 gene and inherited in an autosomal recessive manner. | |

What is (are) Children's interstitial lung disease ? | Children's interstitial and diffuse lung disease (chILD) is not a single condition, but a group of rare lung diseases found in infants, children and adolescents that can range from mild to severe. All types of chILD decrease a child's ability to supply oxygen to their body. These diseases make it difficult for the lungs to exchange oxygen and carbon dioxide and can cause fluid and other materials to collect in the lungs. Early diagnosis and treatment is important for any type of chILD. See the Children's Interstitial Lung Disease Foundation to see a list of different ILDs and to find more information about diagnosis, treatment and help finding a specialist. | |
What are the treatments for Children's interstitial lung disease ? | How might chILD be treated? There is no single treatment for interstitial lung diseases in children. Different forms of chILD require different treatments and support depending on the condition. The goals of treatment for chILD is to relieve symptoms, provide support to maximize growth and development, and to prevent exposure to preventable illnesses that could make the chILD worse. See the Children's Interstitial and Diffuse Lung Disease Foundation for more detailed information about treatment. | |
What is (are) Exstrophy-epispadias complex ? | Exstrophy-epispadias complex (EEC) comprises a spectrum of congenital abnormalities that includes epispadias, classical bladder exstrophy and exstrophy of the cloaca and several variants. EEC is characterized by a visible defect of the lower abdominal wall and other problems. The defect occurs due to a rupture of a fetal tissue known as the cloacal membrane during the first trimester of pregnancy. This results in the abnormal development of the abdominal wall of the fetus. The exact timing of the rupture determines whether the child is born with isolated epispadias, classic bladder exstrophy or cloacal exstrophy. Therefore, depending on severity, EEC may involve the urinary system, musculoskeletal system, pelvis, pelvic floor, abdominal wall, genitalia, and sometimes the spine and anus. There is no known cause for this condition. Treatment may involve several surgeries to repair the abdominal wall and any associated malformation. The University of Michigan has a webpage about the development of the embryo and its parts, including the formation of the cloaca. | |

What is (are) Multiple endocrine neoplasia type 1 ? | Multiple endocrine neoplasia, type 1 (MEN1) is an inherited condition that causes tumors of the endocrine system (the body's network of hormone-producing glands). People affected by MEN1 typically develop tumors of the parathyroid gland, the pituitary gland, and the pancreas, although other glands may be involved as well. These tumors are often "functional" and secrete excess hormones, which can cause a variety of health problems. The most common signs and symptoms of MEN1 are caused by hyperparathyroidism (overactive parathyroid gland) and may include kidney stones; thinning of bones; nausea and vomiting; high blood pressure (hypertension); weakness; and fatigue. MEN1 is caused by changes (mutations) in the MEN1 gene and is inherited in an autosomal dominant manner. Management for MEN1 usually includes regular screening to allow for early diagnosis and treatment of endocrine tumors. | |
What are the symptoms of Multiple endocrine neoplasia type 1 ? | What are the signs and symptoms of Multiple endocrine neoplasia type 1? Multiple endocrine neoplasia, type 1 (MEN1) is characterized primarily by several different types of endocrine tumors. People affected by MEN1 typically develop tumors of the parathyroid gland, the pituitary gland, and the pancreas, although other glands may be involved as well. These tumors are often "functional" and secrete excess hormones, which causes many of the different signs and symptoms of the condition. A variety of non-endocrine tumors are also found in MEN1, including lipomas (fatty tumors); and tumors of the skin or the central nervous system (brain and spinal cord). Signs and symptoms of MEN1 vary and largely depend on which endocrine glands are affected: Parathyroid tumors are present in 90% of people with MEN1 by age 20-25 years and may cause fatigue, depression, weight loss, constipation, nausea, vomiting, dehydration, kidney stones, fragile bones, and hypertension. Pituitary tumors can lead to headaches, vision problems, nausea and vomiting. In women, menstrual periods may become irregular or stop completely. Men may have decreased fertility, diminished sexual desire, and/or erectile dysfunction. Stomach, bowel or pancreas (also called the gastro-entero-pancreatic, or GEP tract) tumors can cause high blood sugar, weight loss, glossitis, anemia, diarrhea, blood clots, and skin rash. Adrenal tumors can cause a variety of symptoms depending on the type of hormones they secrete, including high blood pressure, irregular heartbeat, panic attacks, headaches, diabetes, abdominal pain, weakness, excessive hair growth, and stretch marks. Carcinoid tumors (slow-growing tumors that usually begin in the lining of the lungs or the digestive tract can cause flushing of the face and upper chest; diarrhea; and trouble breathing. The tumors that develop in MEN1 are often benign; however, in some cases, they can become malignant (cancerous). Gastrinomas (a specific type of GEP tract tumor) and carcinoid tumors are the most likely to advance to cancer. The Human Phenotype Ontology provides the following list of signs and symptoms for Multiple endocrine neoplasia type 1.

What causes Multiple endocrine neoplasia type 1 ? | What causes multiple endocrine neoplasia, type 1? Multiple endocrine neoplasia, type 1 (MEN1) is caused by mutations in the MEN1 gene. MEN1 is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Changes (mutations) in MEN1 result in a defective protein that is unable to carry out its normal role. This leads to the development of the many different types of tumors found in MEN1. | |
Is Multiple endocrine neoplasia type 1 inherited ? | How is multiple endocrine neoplasia, type 1 inherited? Multiple endocrine neoplasia, type 1 (MEN1) 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 MEN1 has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Multiple endocrine neoplasia type 1 ? | Is genetic testing available for multiple endocrine neoplasia, type 1? Yes, genetic testing is available for MEN1, the gene known to cause multiple endocrine neoplasia, type 1 (MEN1). 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 multiple endocrine neoplasia, type 1 diagnosed? A diagnosis of multiple endocrine neoplasia, type 1 (MEN1) is based on the presence of two of the following endocrine tumors: parathyroid tumors; pituitary tumors; and/or stomach, bowel or pancreas (also called the gastro-entero-pancreatic, or GEP tract) tumors. People with only one of the tumors may also receive a diagnosis of MEN1 if they have other family members with the condition. Identification of a change (mutation) in the MEN1 gene can be used to confirm the diagnosis. In addition to a complete physical exam and medical history, laboratory tests that evaluate the levels of certain hormones in the blood or urine are often used detect the different types of tumors found in MEN1. Imaging studies such as computed tomography (CT scan), magnetic resonance imaging (MRI scan), and/or endoscopic ultrasound may be recommended to confirm the location and size of the tumors. Some people may also need a biopsy of the tumor to confirm the diagnosis. | |
What are the treatments for Multiple endocrine neoplasia type 1 ? | How might multiple endocrine neoplasia, type 1 be treated? People with multiple endocrine neoplasia, type 1 (MEN1) are usually managed with regular screening to allow for early diagnosis and treatment of endocrine tumors. This screening begins in early childhood and continues for life. Recommended screening includes specific types of imaging studies every 3-5 years: Head magnetic resonance imaging (MRI scan) begining at age 5. Abdominal computed tomography (CT scan) or abdominal MRI scan beginning at age 20. Annual blood tests are also recommended, which evaluate the levels of certain substances that can be elevated if an MEN1-associated tumor is present: Prolactin concentrations, which can be used to screen for pituitary tumors, are measured beginning at age 5. Calcium concentrations, which can be used to screen for parathyroid tumors, are measured beginning at age 8. Gastrin concentrations, which can be used to screen for gastrinomas (a specific type of gastro-entero-pancreatic tract tumor) are measured beginning at age 20. When a tumor is detected through screening, the best treatment options depend on many factors, including the size, location, and type of tumor; and whether or not the tumor is "functional" (releasing hormones). Many tumors are treated with surgery. If a tumor is functional, removal of the affected endocrine gland often resolves health problems that may be present as a result of elevated hormones. In some cases, functional tumors can be treated with medications that block the function or lower the levels of the overproduced hormone. Chemotherapy or radiation therapy may also be used to to shrink or destroy tumors. | |

What is (are) Dermatitis herpetiformis ? | Dermatitis herpetiformis is a rare, chronic, skin disorder characterized by groups of severely itchy blisters and raised skin lesions. These are more common on the knees, elbows, buttocks and shoulder blades. The slow onset of symptoms usually begins during adulthood, but children can also be affected. Other symptoms may include fluid-filled sores; red lesions that resemble hives; and itchiness, redness and burning. The exact cause of this disease is not known, but it is frequently associated with the inability to digest gluten. People with this disease are typically treated with the drug dapsone. | |

What are the treatments for Dermatitis herpetiformis ? | How might dermatitis herpetiformis be treated? The antibiotic dapsone is extremely effective in treating this condition. Symptomatic improvement may occur in as little as several hours after the first dose. However, dapsone may cause serious side effects and requires regular monitoring by a physician. When this medication is used to relieve the symptoms of dermatitis herpetiformis, it should be taken in the smallest effective dose and for the shortest period possible. In some cases, immunosuppressive medications may be used. These medications do not appear to be as effective. A strict gluten-free diet is also recommended to help control the disease. Following this diet may eliminate the need for medications and prevent later complications. | |

What is (are) Langerhans cell histiocytosis ? | Langerhans cell histiocytosis (LCH) is a disorder that primarily affects children, but is also found in adults of all ages. People with LCH produce too many Langerhans cells or histiocytes, a form of white blood cell found in healthy people that is supposed to protect the body from infection. In people with LCH, these cells multiply excessively and build up in certain areas of the body, causing tumors called granulomas to form. The symptoms vary among affected individuals, and the cause of LCH is unknown. In most cases, this condition is not life-threatening. Some people do experience life-long problems associated with LCH. | |
What are the symptoms of Langerhans cell histiocytosis ? | What are the signs and symptoms of Langerhans cell histiocytosis? Symptoms of Langerhans cell histiocytosis (LCH) can vary greatly from person to person depending on how much of the body is involved and what part(s) are affected. The disease can affect virtually every organ, including skin, bones, lymph nodes, bone marrow, liver, spleen, lungs, gastrointestinal tract, thymus, central nervous system, and hormone glands. The symptoms may range from localized bone lesions or skin disease to multiple organ involvement and severe dysfunction. Below are the organs that may be affected as well as the symptoms that might be observed: Skin - Red, scaly papules in areas where opposing skin surfaces touch or rub (e.g. skin folds) are commonly seen in LCH. Infants with the skin presentation on the scalp are often misdiagnosed with cradle cap. The skin symptoms usually improve without treatment. Bone - Lesions that cause bone destruction are common, with the skull, lower limbs, ribs, pelvis, and vertebrae usually being affected. Symptoms may include pain, swelling, limited motion, and inability to bear weight. Lymph node - Lymph node involvement may be limited or associated with a skin or bone lesion or disseminated disease. Although any of the lymph nodes may be affected, the cervical lymph nodes are where the disease commonly occurs. Individuals usually only present with pain of the lymph node affected. If only one lymph node is affected, prognosis is normally good and treatment is unnecessary. Liver - Liver involvement at the time of diagnosis is generally associated with more severe disease. Symptoms may include ascites, jaundice, low levels of protein, and prolonged clotting time. Central nervous system (CNS) and hormone - CNS involvement is rare and may be devastating. The most common result of CNS involvement is the altering of hormonal function, with some individuals developing diabetes insipidus. More detailed information about the symptoms of LCH can be accessed through the Histiocytosis Association's website. | |
What causes Langerhans cell histiocytosis ? | What causes Langerhans cell histiocytosis? The cause of Langerhans cell histiocytosis is unknown. It may be triggered by an unusual reaction of the immune system to something commonly found in the environment. It is not considered to be an infection or cancer. It is not known to be hereditary or communicable. | |
Is Langerhans cell histiocytosis inherited ? | Is Langerhans cell histiocytosis inherited? Although Langerhans cell histiocytosis is generally considered a sporadic, non-hereditary condition, it has reportedly affected more than one individual in a family in a very limited number of cases (particularly identical twins). | |
How to diagnose Langerhans cell histiocytosis ? | How is Langerhans cell histiocytosis diagnosed? Testing for Langerhans cell histiocytosis (LCH) may include bronchoscopy with biopsy, x-ray, skin biopsy, bone marrow biopsy, complete blood count, and pulmonary function tests. Because LCH is sometimes associated with cancer, CT scans and a biopsy may be done to rule out possible cancer. Additional information about the diagnosis of LCH can be viewed on the Histiocytosis Association's website. | |
What are the treatments for Langerhans cell histiocytosis ? | How might Langerhans cell histiocytosis be treated? Treatment for Langerhans cell histiocytosis (LCH) depends upon the individual patient; it may differ depending on the type and severity of the condition as well as what part(s) of the body are affected. In some cases, the disease will regress without any treatment at all. In other cases, limited surgery and small doses of radiation therapy or chemotherapy will be needed, depending on the extent of the disease. Treatment is planned after complete evaluation of the patient, with the goal of using as little treatment as possible to keep the disease under control. Detailed information about the treatment of LCH can be viewed on Medscape Reference's Web site. | |

What is (are) Lichen planus pigmentosus ? | Lichen planus pigmentosus (LPP) is a rare form of lichen planus. It is characterized by oval or irregularly shaped brown to gray-brown macules and patches on the skin. Areas that are exposed to sun such as the forehead, temples and neck are most commonly affected. However, the macules and patches may also develop on the trunk or in places where two areas of skin touch or rub together (i.e. the armpit, groin, etc). LPP is a chronic, relapsing condition with periods of exacerbations (worsening symptoms) separated by periods of remission (a decrease in or disappearance of symptoms). Although the exact underlying cause of LPP is unknown, studies suggest that UV light, viral infections, and certain topical (applied to the skin) agents such as mustard oil and amla oil, may trigger the condition. Treatment for LPP is symptomatic. | |

What is (are) Interstitial cystitis ? | Interstitial cystitis (IC) is a condition that causes discomfort or pain in the bladder and abdomen. Symptoms may vary, but often include an urgent or frequent need to urinate. Many of the individuals affected by IC are women. Because IC varies so much in symptoms and severity, most researchers believe it is not one, but several diseases. In recent years, scientists have started to use the terms bladder pain syndrome (BPS) or painful bladder syndrome (PBS) to describe cases with painful urinary symptoms that may not meet the strictest definition of IC. While there is no cure for IC/PBS, in many cases, the symptoms can be managed. Treatments include dietary and lifestyle changes; distending, or inflating, the bladder; bathing the inside of the bladder with a medicine solution; oral medicines and in rare cases, surgery. | |
What is (are) Pretibial epidermolysis bullosa ? | Pretibial epidermolysis bullosa is a rare form of epidermolysis bullosa, a condition characterized by fragile skin that blisters easily in response to minor injury or friction. In the pretibial form, specifically, the characteristic blisters and skin erosions develop predominantly on the front of the lower legs (known as the "pretibial region"). In some affected people, the feet, hands and/or nails may also be affected. Healing of the blisters is generally associated with hypertrophic scarring. Pretibial epidermolysis bullosa is caused by changes (mutations) in the COL7A1 gene and can be inherited in an autosomal dominant or autosomal recessive manner. Treatment is based on the signs and symptoms present in each person. |
