A health care provider may treat kidney failure due to diabetic kidney disease with dialysis or a kidney transplant. In some cases, people with diabetic kidney disease receive kidney and pancreas transplants. In most cases, people with diabetic kidney disease start dialysis earlier than people with kidney failure who do not have diabetes. People with diabetic end-stage kidney disease who receive a kidney transplant have a much better survival rate than those people on dialysis, although survival rates for those on dialysis have increasingly improved over time. However, people who receive a kidney transplant and do not have diabetes have a higher survival rate than people with diabetic kidney disease who receive a transplant.5 More information about treatment options for kidney failure is provided in the NIDDK health topics: - Treatment Methods for Kidney Failure: Hemodialysis - Treatment Methods for Kidney Failure: Peritoneal Dialysis - Treatment Methods for Kidney Failure: Transplantation
Adrenal function must be tested periodically in all patients with ALD. Treatment with adrenal hormones can be lifesaving. Symptomatic and supportive treatments for ALD include physical therapy, psychological support, and special education. Recent evidence suggests that a mixture of oleic acid and erucic acid, known as "Lorenzo's Oil," administered to boys with X-ALD prior to symptom onset can prevent or delay the appearance of the childhood cerebral form It is not known whether Lorenzo's Oil will have any beneficial effects in AMN. Furthermore, Lorenzo's Oil has no beneficial effect in symptomatic boys with X-ALD. Bone marrow transplantations can provide long-term benefit to boys who have early evidence of the childhood cerebral form of X-ALD, but the procedure carries risk of mortality and morbidity and is not recommended for those whose symptoms are already severe or who have the adult-onset or neonatal forms.
The prognosis for individuals with VHL depends on then number, location, and complications of the tumors. Untreated, VHL may result in blindness and/or permanent brain damage. With early detection and treatment the prognosis is significantly improved. Death is usually caused by complications of brain tumors or kidney cancer.
The NINDS supports and conducts research on neurodegenerative disorders, such as tabes dorsalis, in an effort to find ways to prevent, treat, and, ultimately, cure these disorders.
Leri Weill dyschondrosteosis is a skeletal dysplasia characterized by short stature and an abnormality of the wrist bones called Madelung deformity. Short stature is present from birth due to shortening of the long bones in the legs. Madelung deformity typically develops during mid-to-late childhood and may progress during puberty. People with this condition often experience pain in their wrists or arms. The severity of Leri Weill dyschondrosteosis varies among affected individuals, although the signs and symptoms of this condition are generally more severe in females. Other features of Leri Weill dyschondrosteosis can include increased muscle size, bowing of a bone in the leg called the tibia, elbow abnormalities, scoliosis, and high-arched palate. Intelligence is not affected by this condition. Most cases of Leri Weill dyschondrosteosis are caused by mutations in or near the SHOX gene. The cause of the disorder remains unknown in those cases not related to the SHOX gene. Leri Weill dyschondrosteosis follows a pseudoautosomal dominant pattern of inheritance.
The exact incidence of MELAS is unknown. It is one of the more common conditions in a group known as mitochondrial diseases. Together, mitochondrial diseases occur in about 1 in 4,000 people.
The respiratory failure and paralysis that occur with severe botulism may require a patient to be on a breathing machine (ventilator) for weeks or months, plus intensive medical and nursing care. The paralysis slowly improves. Botulism can be treated with an antitoxin which blocks the action of toxin circulating in the blood. Antitoxin for infants is available from the California Department of Public Health, and antitoxin for older children and adults is available through CDC.If given before paralysis is complete, antitoxin can prevent worsening and shorten recovery time. Physicians may try to remove contaminated food still in the gut by inducing vomiting or by using enemas. Wounds should be treated, usually surgically, to remove the source of the toxin-producing bacteria followed by administration of appropriate antibiotics. Good supportive care in a hospital is the mainstay of therapy for all forms of botulism.
How might meningiomas be treated? The treatment varies depending on the location of the meningioma and the symptoms caused by the tumor. Careful observation is sometimes the best course of action for people with a meningioma. When treatment is necessary, surgery and radiation are the most common forms of treatment. Radiation may be used if the meningioma cannot be operated on or if the meningioma is only partially removed by surgery. Radiation may also be used in cases of malignant, atypical, or recurrent tumors. Other treatments that have been tried or are being explored include hydroxyurea, epidermal growth factor receptor inhibitors, platelet-derived growth factor receptor inhibitors, vascular endothelial growth factor inhibitors, immunotherapy to stimulate the immune system, and somatostatin analogs which prevent the release of growth hormones.
The prevalence of enlarged parietal foramina is estimated to be 1 in 15,000 to 50,000 individuals.

Krabbe disease is a rare, inherited metabolic disorder in which harmful amounts of lipids (fatty materials such as oils and waxes) build up in various cells and tissues in the body and destroys brain cells. Krabbe disease, also known as globoid cell leukodystrophy, ischaracterized by the presence of globoid cells (cells that have more than one nucleus) that break down the nerves protective myelin coating. Krabbe disease is caused by a deficiency of galactocerebrosidase, an essential enzyme for myelin metabolism. The disease most often affects infants, with onset before age 6 months, but can occur in adolescence or adulthood. Symptoms include severe deterioration of mental and motor skills, muscle weakness, hypertonia (inability of a muscle to stretch), myoclonic seizures (sudden, shock-like contractions of the limbs), and spasticity (involuntary and awkward movement). Other symptoms may include irritability, unexplained fever, blindness, difficulty with swallowing, and deafness.
How is Leber hereditary optic neuropathy (LHON) inherited? Leber hereditary optic neuropathy is an inherited condition that has a mitochondrial pattern of inheritance. The gene mutations that cause this condition are found in the mitochondrial DNA. Mitochondria are inherited from a person's mother, and as a result, only females pass mitochondrial conditions on to their children. Men can be affected, but they cannot pass the condition on to their children. Often, people who develop the features of Leber hereditary optic neuropathy have no family history of the condition. Because a person may carry a mitochondrial DNA mutation without experiencing any signs or symptoms, it is hard to predict which members of a family who carry a mutation will eventually develop vision loss or other medical problems associated with Leber hereditary optic neuropathy. It is important to note that all females with a mitochondrial DNA mutation, even those who do not have any signs or symptoms, will pass the genetic change to their children.
Giant axonal neuropathy (GAN) is a neurodegenerative disorder characterized by abnormally large and dysfunctional axons (the specialized extensions of nerve cells that are required for the transmission of nerve impulses). The condition typically appears in infancy or early childhood with severe peripheral motor and sensory neuropathy (affecting movement and sensation in the arms and legs). Early signs include difficulty walking, lack of coordination, and loss of strength. Over time, the central nervous system (brain and spinal cord) becomes involved, causing a gradual decline in mental function, loss of control of body movements, and seizures. Giant axonal neuropathy is caused by mutations in the GAN gene. It follows and autosomal dominant pattern of inheritance. Management is directed by a multidisciplinary team with the goal of optimizing intellectual and physical development.
5-alpha reductase deficiency is a rare condition; the exact incidence is unknown. Large families with affected members have been found in several countries, including the Dominican Republic, Papua New Guinea, Turkey, and Egypt.
How might factor XIII be treated? The amount of Factor XIII necessary for a normal response to trauma is only about 10 percent of that in the normal plasma. People with Factor XIII deficiency are generally given small infusions of fresh or frozen blood plasma (cryoprecipitates), or Factor XIII concentrates every three or four weeks. This has proven to be a highly successful preventive treatment for the disorder. Patients typically have a normal response to trauma while on these transfusions. When patients with Factor XIII deficiency have a high incidence of bleeding inside the head (intracranial), preventive treatment is necessary. In February 2011, the US Food and Drug Administration approved Corifact, a product manufactured by CSL Behring of Marburg, Germany, to prevent bleeding in people with congenital Factor XIII deficiency. Corifact is made from the pooled plasma of healthy donors. It can be used for individuals with absent or decreased levels of FXIII. People receiving Corifact may develop antibodies against Factor XIII that may make the product ineffective. It potentially can cause adverse events from abnormal clotting if doses higher than the labeled dose are given to patients. Cryoprecipitate should not be used to treat patients with factor XIII deficiency except in life- and limb-threatening emergencies when Factor XIII concentrate is not immediately available.
Metachromatic leukodystrophy is an inherited condition characterized by the accumulation of fats called sulfatides in cells, especially cells of the nervous system. This accumulation results in progressive destruction of white matter of the brain, which consists of nerve fibers covered by myelin. Affected individuals experience progressive deterioration of intellectual functions and motor skills, such as the ability to walk. They also develop loss of sensation in the extremities, incontinence, seizures, paralysis, inability to speak, blindness, and hearing loss. Eventually they lose awareness of their surroundings and become unresponsive. This condition is inherited in an autosomal recessive pattern and is caused by mutations in the ARSA and PSAP genes.
The goals of psoriasis treatment are to change the course of the disease by interfering with the increased production of skin cells, and to remove scales and smooth rough skin.
There is no specific treatment for SD. For people with the mildest form, bed rest during the period of active movements is sufficient. When the severity of movements interferes with rest, sedative drugs, such as barbiturates or benzodiazepines, may be needed. Antiepileptic medications, such as valproic acid, are often prescribed. Doctors also recommend that children who have had SD take penicillin over the course of the next 10 years to prevent additional manifestations of rheumatic fever.
Wilson disease is a genetic disease that prevents the body from removing extra copper. The body needs a small amount of copper from food to stay healthy; however, too much copper is poisonous. Normally, the liver filters extra copper and releases it into bile. Bile is a fluid made by the liver that carries toxins and wastes out of the body through the gastrointestinal tract. In Wilson disease, the liver does not filter copper correctly and copper builds up in the liver, brain, eyes, and other organs. Over time, high copper levels can cause life-threatening organ damage.
Progressive osseous heteroplasia is a disorder in which bone forms within skin and muscle tissue. Bone that forms outside the skeleton is called heterotopic or ectopic bone. In progressive osseous heteroplasia, ectopic bone formation begins in the deep layers of the skin (dermis and subcutaneous fat) and gradually moves into other tissues such as skeletal muscle and tendons. The bony lesions within the skin may be painful and may develop into open sores (ulcers). Over time, joints can become involved, resulting in impaired mobility. Signs and symptoms of progressive osseous heteroplasia usually become noticeable during infancy. In some affected individuals, however, this may not occur until later in childhood or in early adulthood.
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.

The Maat-Kievit-Brunner type of Ohdo syndrome results from mutations in the MED12 gene. This gene provides instructions for making a protein that helps regulate gene activity; it is thought to play an essential role in development both before and after birth. The MED12 gene mutations that cause this condition alter the structure of the MED12 protein, impairing its ability to control gene activity. It is unclear how these changes lead to the particular cognitive and physical features of the Maat-Kievit-Brunner type of Ohdo syndrome.
Familial HDL deficiency is a condition characterized by low levels of high-density lipoprotein (HDL) in the blood. HDL is a molecule that transports cholesterol and certain fats called phospholipids through the bloodstream from the body's tissues to the liver. Once in the liver, cholesterol and phospholipids are redistributed to other tissues or removed from the body. HDL is often referred to as "good cholesterol" because high levels of this substance reduce the chances of developing heart and blood vessel (cardiovascular) disease. People with familial HDL deficiency may develop cardiovascular disease at a relatively young age, often before age 50. Severely reduced levels of HDL in the blood is a characteristic feature of a related disorder called Tangier disease. People with Tangier disease have additional signs and symptoms, such as disturbances in nerve function; enlarged, orange-colored tonsils; and clouding of the clear covering of the eye (corneal clouding). However, people with familial HDL deficiency do not have these additional features.
The inheritance pattern of Crohn disease is unclear because many genetic and environmental factors are likely to be involved. This condition tends to cluster in families, however, and having an affected family member is a significant risk factor for the disease.
How might eosinophilic fasciitis be treated? About 10-20% of people with eosinophilic fasciitis recover spontaneously without treatment. For those who do not, glucocorticoids (0.51 mg/kg/d), such as prednisone, are the mainstay therapy. Even with treatment, improvement in symptoms can take weeks or months. Glucocorticoids are successful in treating eosionophilic fasciitis in over 70% of cases. If glucocorticoids are unsuccessful, methotrexate at low doses (1525 mg once weekly) is probably the most favored second-line treatment, especially in people with reddish to purpleish (morphea-like) skin lesions. Other treatment options include NSAIDs, D-penicillamine, chloroquine, cimetidine, azathioprine, cyclosporin A, infliximab, UVA-1, and bath PUVA. Physical therapy may help improve joint mobility and decrease contractures. Surgical release has been used in some severe cases to manage significant joint contractures.
Prostate cancer is most common in older men. In the U.S., about one out of five men will be diagnosed with prostate cancer. Most men diagnosed with prostate cancer do not die of it. See the following PDQ summaries for more information about prostate cancer: - Prostate Cancer Screening - Prostate Cancer Treatment
There is no cure for TSC, although treatment is available for a number of the symptoms. Rapamycin and related drugs are not yet approved by the U.S. Food and Drug Administration (FDA) for any purpose in individuals with TSC. The FDA has approved the drug everolimus (Afinitor) to treat subependymal giant cell astrocytomas (SEGA brain tumors) and angiomyolipoma kidney tumors. Antiepileptic drugs such as vigabatrin may be used to control seizures and medications may be prescribed for behavior problems. Intervention programs, including special schooling and occupational therapy, may benefit individuals with special needs and developmental issues. Surgery, including dermabrasion and laser treatment, may be useful for treatment of skin lesions. Because TSC is a lifelong condition, individuals need to be regularly monitored by a doctor. Due to the many varied symptoms of TSC, care by a clinician experienced with the disorder is recommended.
Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs. Hyperthyroidism is sometimes called thyrotoxicosis, the technical term for too much thyroid hormone in the blood. Thyroid hormones circulate throughout the body in the bloodstream and act on virtually every tissue and cell in the body. Hyperthyroidism causes many of the bodys functions to speed up. About 1 percent of the U.S. population has hyperthyroidism.1

What are the signs and symptoms of Trigeminal neuralgia? The Human Phenotype Ontology provides the following list of signs and symptoms for Trigeminal neuralgia. 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) Autosomal dominant inheritance - Trigeminal neuralgia - 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.
Sudden sensorineural deafness is a condition that is characterized by rapid, unexplained hearing loss. More specifically, affected people experience a reduction in hearing of greater than 30 decibels, which may occur all at once or over several days. In most cases, only one ear is affected. People with sudden sensorineural deafness often become dizzy, have ringing in their ears (tinnitus), or both (40% of the cases). The condition has a variety of causes, including infection, inflammation, tumors, trauma, exposure to toxins and conditions that affect the inner ear such as Mnire's disease. About half of people with sudden sensorineural deafness will recover some or all of their hearing spontaneously and about 85% of those who receive treatment will recover some of their hearing.
Treatment for Sturge-Weber syndrome is symptomatic. Laser treatment may be used to lighten or remove the birthmark. Anticonvulsant medications may be used to control seizures. Persons with drug-resistant seizures may be treated by surgical removal of epileptic brain tissue. Surgery may be performed on more serious cases of glaucoma. Physical therapy should be considered for infants and children with muscle weakness. Educational therapy is often prescribed for those with impaired cognition or developmental delays. Doctors recommend yearly monitoring for glaucoma.
If you are having surgery, your doctor will give you medicine called an anesthetic. Anesthetics reduce or prevent pain. There are three main types: - Local - numbs one small area of the body. You stay awake and alert. - Regional - blocks pain in an area of the body, such an arm or leg. A common type is epidural anesthesia, which is often used during childbirth. - General - makes you unconscious. You do not feel any pain, and you do not remember the procedure afterwards. You may also get a mild sedative to relax you. You stay awake but may not remember the procedure afterwards. Sedation can be used with or without anesthesia. The type of anesthesia or sedation you get depends on many factors. They include the procedure you are having and your current health.

Early-onset primary dystonia is among the most common forms of childhood dystonia. This disorder occurs most frequently in people of Ashkenazi (central and eastern European) Jewish heritage, affecting 1 in 3,000 to 9,000 people in this population. The condition is less common among people with other backgrounds; it is estimated to affect 1 in 10,000 to 30,000 non-Jewish people worldwide.
Summary : Cosmetics are products you apply to your body to clean it, make it more attractive, or change the way it looks. They include - Hair dyes - Makeup - Perfumes - Skin-care creams Cosmetics that treat or prevent diseases are also drugs. Products such as dandruff shampoo, fluoride toothpaste, and antiperspirant deodorant are both cosmetics and drugs. A good way to tell if you're buying a cosmetic that is also a drug is to see if the first ingredient listed is an "active ingredient." The active ingredient is the chemical that makes the product effective. The manufacturer must have proof that it's safe for its intended use. Cosmetics can cause allergic reactions. The first sign is often red and irritated skin. Fragrances and preservatives are the most common causes of skin problems. To find out all the ingredients in a cosmetic you use, check the container. Manufacturers are required to list them. Labels such as "natural" and "hypoallergenic" have no official meaning. Companies can use them to mean whatever they want. Food and Drug Administration
Are anaplastic astrocytomas inherited? Anaplastic astrocytomas are usually not inherited. These tumors typically occur sporadically, in people with no family history of astrocytomas. In most cases, the exact cause is unknown. Familial cases of isolated astrocytomas have been reported but are very rare. Astrocytomas can have a genetic link when they are associated with a few rare, inherited disorders. These include neurofibromatosis type I, Li-Fraumeni syndrome, Turcot syndrome, and tuberous sclerosis. Astrosytomas occur more frequently in people with one of these disorders. Like many other cancers, it is believed that isolated astrocytomas may occur due to a combination of genetic and environmental factors. This means that a person may carry a gene (or a combination of genes) that predisposes them to developing an astrocytoma, but it may not develop unless it is "triggered" by an environmental factor.

The risk factors for depression are family history, life experiences, and environment. If you have depression, you may have experienced it when you were younger, and may have a family history of the illness. You may also be going through difficult life events, such as physical or psychological trauma, losing a loved one, a difficult relationship with a family member or friend, or financial troubles. Any of these stressful experiences can lead to depression. For older adults who experience depression for the first time later in life, other factors may be at play. Depression may be related to changes that occur in the brain and body as a person ages. For example, some older adults who are at risk for illnesses such as heart disease or stroke may have hardening and inflammation of the blood vessels, and blood may not be able to flow normally to the body's organs, including the brain. Over time, this blood vessel disease and restricted blood flow can damage nearby brain tissue and harm the nerve connections that help different parts of the brain communicate with each other. If this happens, an older adult with no family history of depression may develop what some doctors call "vascular depression." Older adults may also experience depression as a result of brain changes caused by illnesses such as Alzheimers disease or Parkinsons disease. This type of depression can appear in the early stages of these diseases, before many symptoms appear.
Nearly 2.7 million people have glaucoma, a leading cause of blindness in the United States. Although anyone can get glaucoma, some people are at higher risk. They include - African-Americans over age 40 - everyone over age 60, especially Hispanics/Latinos - people with a family history of glaucoma. African-Americans over age 40 everyone over age 60, especially Hispanics/Latinos people with a family history of glaucoma. In addition to age, eye pressure is a risk factor. Whether you develop glaucoma depends on the level of pressure your optic nerve can tolerate without being damaged. This level is different for each person. Thats why a comprehensive dilated eye exam is very important. It can help your eye care professional determine what level of eye pressure is normal for you. Another risk factor for optic nerve damage relates to blood pressure. Thus, it is important to also make sure that your blood pressure is at a proper level for your body by working with your medical doctor. (Watch the animated video to learn more about the causes of glaucoma. To enlarge the video, click the brackets in the lower right-hand corner.

The most common symptoms of gas are: - Burping. Burping once in awhile, especially during and after meals, is normal. If you burp very often, you may be swallowing too much air. Some people with digestive problems swallow air on purpose and burp because they believe it will help them feel better. - Passing gas. Passing gas around 13 to 21 times a day is normal. If you think you pass gas more often than that, you may have trouble digesting certain carbohydrates. - Bloating. Bloating is a feeling of fullness and swelling in the abdomen, the area between the chest and hips. Disorders such as irritable bowel syndrome (IBS) can affect how gas moves through the intestines. If gas moves through your intestines too slowly, you may feel bloated. - Abdominal pain or discomfort. People may feel abdominal pain or discomfort when gas does not move through the intestines normally. People with IBS may be more sensitive to gas in the intestines.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Aspergillosis is an infection, growth, or allergic response caused by the Aspergillus fungus. There are several different kinds of aspergillosis. One kind is allergic bronchopulmonary aspergillosis (also called ABPA), a condition where the fungus causes allergic respiratory symptoms similar to asthma, such as wheezing and coughing, but does not actually invade and destroy tissue. Another kind of aspergillosis is invasive aspergillosis. This infection usually affects people with weakened immune systems due to cancer, AIDS, leukemia, organ transplantation, chemotherapy, or other conditions or events that reduce the number of normal white blood cells. In this condition, the fungus invades and damages tissues in the body. Invasive aspergillosis most commonly affects the lungs, but can also cause infection in many other organs and can spread throughout the body (commonly affecting the kidneys and brain). Aspergilloma, a growth (fungus ball) that develops in an area of previous lung disease such as tuberculosis or lung abscess, is a third kind of aspergillosis. This type of aspergillosis is composed of a tangled mass of fungus fibers, blood clots, and white blood cells. The fungus ball gradually enlarges, destroying lung tissue in the process, but usually does not spread to other areas.
How is multiple familial trichoepithelioma inherited? Susceptibility to multiple familial trichoepithelioma has an autosomal dominant pattern of inheritance. This means that one copy of the altered gene in each cell increases the risk that a person will develop the condition. However, a second, non-inherited mutation is needed for development of the skin tumors characteristic of this condition.

This condition is inherited in an X-linked recessive pattern. The gene associated with this condition is located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. In females (who have two X chromosomes), a mutation would have to occur in both copies of the gene to cause the disorder. Because it is unlikely that females will have two altered copies of this gene, males are affected by X-linked recessive disorders much more frequently than females. A characteristic of X-linked inheritance is that fathers cannot pass X-linked traits to their sons.
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Some people who have the altered gene never develop the condition, a situation known as reduced penetrance.
Mntriers disease causes the ridges along the inside of the stomach wallcalled rugaeto enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall. In a normal stomach, mucous cells in the rugae release protein-containing mucus. The mucous cells in enlarged rugae release too much mucus, causing proteins to leak from the blood into the stomach. This shortage of protein in the blood is known as hypoproteinemia. Mntriers disease also reduces the number of acid-producing cells in the stomach, which decreases stomach acid. Mntriers disease is also called Mntrier disease or hypoproteinemic hypertrophic gastropathy.
Certain factors affect treatment options and prognosis (chance of recovery). The prognosis (chance of recovery) and treatment options depend on the following: - The type of ovarian cancer and how much cancer there is. - The stage and grade of the cancer. - Whether the patient has extra fluid in the abdomen that causes swelling. - Whether all of the tumor can be removed by surgery. - Whether there are changes in the BRCA1 or BRCA2 genes. - The patients age and general health. - Whether the cancer has just been diagnosed or has recurred (come back).
People with anemia caused by iron, vitamin B12, or folic acid deficiencies are usually advised to include sources of these nutrients in their diets. Dietary sources of iron include - beans - breakfast cereals - chicken - enriched bread - spinach - turkey Dietary sources of vitamin B12 include - beef liver - breakfast cereals - chicken - clams - fish - turkey Dietary sources of folic acid include - beans - breakfast cereals - chicken - enriched bread - rice - turkey
Aniridia is an eye disorder characterized by a complete or partial absence of the colored part of the eye (the iris). These iris abnormalities may cause the pupils to be abnormal or misshapen. Aniridia can cause reduction in the sharpness of vision (visual acuity) and increased sensitivity to light (photophobia). People with aniridia can also have other eye problems. Increased pressure in the eye (glaucoma) typically appears in late childhood or early adolescence. Clouding of the lens of the eye (cataracts), occur in 50 percent to 85 percent of people with aniridia. In about 10 percent of affected people, the structures that carry information from the eyes to the brain (optic nerves) are underdeveloped. Individuals with aniridia may also have involuntary eye movements (nystagmus) or underdevelopment of the region at the back of the eye responsible for sharp central vision (foveal hypoplasia). Many of these eye problems contribute to progressive vision loss in affected individuals. The severity of symptoms is typically the same in both eyes. Rarely, people with aniridia have behavioral problems, developmental delay, and problems detecting odors.
Treatment for CCHF is primarily supportive. Care should include careful attention to fluid balance and correction of electrolyte abnormalities, oxygenation and hemodynamic support, and appropriate treatment of secondary infections. The virus is sensitive in vitro to the antiviral drug ribavirin. It has been used in the treatment of CCHF patients reportedly with some benefit. Recovery The long-term effects of CCHF infection have not been studied well enough in survivors to determine whether or not specific complications exist. However, recovery is slow.
Urachal cancer is a rare type of bladder cancer, making up less than 1% of all bladder cancers. Only about 350 cases have been described in the medical literature to date. The urachus is a primitive structure which before birth connected the bellybutton and the bladder. This connection normally disappears before birth, but in some people remains. Urachal cancers are classified as such based on location at the dome or anterior wall of the bladder and discovery of remnants of the urachus. Most urachal cancers are adenocarcinomas (cancers that develop from gland cells). Others may be sarcomas (which develop from connective tissue - such as leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma), small cell carcinomas, transitional cell cancer, and mixed neoplasias. Most individuals with urachal cancer present with hematuria (blood in urine). Other symptoms may include abdominal pain, a palpable abdominal mass, mucinuria, and bacteriuria. Patients who present with early disease confined to the urachus have a good prognosis when treated with partial cystectomy, umbilicotomy, and urachal resection. The prognosis for those with advanced disease is less promising.
Crohn's disease is a disease that causes inflammation,* or swelling, and irritation of any part of the digestive tractalso called the gastrointestinal (GI) tract. The part most commonly affected is the end part of the small intestine, called the ileum. *See the Pronunciation Guide for tips on how to say the words in bold type. Crohns disease is one of two main forms of diseases of the GI tract named inflammatory bowel disease (IBD). The other form, called ulcerative colitis, affects the large intestine, which includes the colon and the rectumthe lower end of the large intestine, leading to the anus. With Crohns disease, chronicor long lastinginflammation may cause scar tissue to form in the lining of the intestine. When scar tissue builds up, the passage can become narrow, causing food and stool to move through the GI tract more slowlywhich can lead to pain, cramps, and diarrhea.
Hepatic encephalopathy is a syndrome observed in some patients with cirrhosis. It is defined as a spectrum of neuropsychiatric abnormalities in patients with liver dysfunction, when other known brain disease has been excluded. Signs and symptoms may be debilitating, and they can begin mildly and gradually, or occur suddenly and severely. They may include personality or mood changes, intellectual impairment, abnormal movements, a depressed level of consciousness, and other symptoms. There are several theories regarding the exact cause, but development of the condition is probably at least partially due to the effect of substances that are toxic to nerve tissue (neurotoxic), which are typically present with liver damage and/or liver disease. Treatment depends upon the severity of mental status changes and upon the certainty of the diagnosis.
Conjunctivitis is the medical name for pink eye. It involves inflammation of the outer layer of the eye and inside of the eyelid. It can cause swelling, itching, burning, discharge, and redness. Causes include - Bacterial or viral infection - Allergies - Substances that cause irritation - Contact lens products, eye drops, or eye ointments Pinkeye usually does not affect vision. Infectious pink eye can easily spread from one person to another. The infection will clear in most cases without medical care, but bacterial pinkeye needs treatment with antibiotic eye drops or ointment. NIH: National Eye Institute
The prevalence of CAV3-related distal myopathy is unknown. Only a few affected individuals have been described in the medical literature.
Dowling-Degos disease appears to be a rare condition, although its prevalence is unknown.
What treatment is available for cleidocranial dysplasia? Because there is no specific treatment for cleidocranial dysplasia, treatment is based on an individual's symptoms. Affected individuals typically require dental care due to various teeth abnormalities. People with cleidocranial dysplasia may receive supplements of calcium and vitamin D if their bone density is below normal, and preventive treatment for osteoporosis is usually started at a young age. Some affected individuals may need ear tubes if they have frequent ear infections. If the cranial vault defect is serious, it is important to protect the head wearing helmets during high-risk activities. Surgery may be needed to correct a depressed forehead or for the enlargement of small clavicles.

Acquired pure red cell aplasia (PRCA) is a bone marrow disorder characterized by a reduction of red blood cells (erythrocytes) produced by the bone marrow. Signs and symptoms may include fatigue, lethargy, and/or abnormal paleness of the skin (pallor) due to the anemia the caused by the disorder. In most cases, the cause of acquired PRCA is unknown (idiopathic). In other cases it may occur secondary to autoimmune disorders, tumors of the thymus gland (thymomas), hematologic cancers, solid tumors, viral infections, or certain drugs. Treatment depends on the cause of the condition (if known) but often includes transfusions for individuals who are severely anemic and have cardiorespiratory failure.

Until recently, the common type of diabetes in children and teens was type 1. It was called juvenile diabetes. With Type 1 diabetes, the pancreas does not make insulin. Insulin is a hormone that helps glucose,or sugar, get into your cells to give them energy. Without insulin, too much sugar stays in the blood. But now younger people are also getting type 2 diabetes. Type 2 diabetes used to be called adult-onset diabetes. But now it is becoming more common in children and teens, due to more obesity. With Type 2 diabetes, the body does not make or use insulin well. Children have a higher risk of type 2 diabetes if they are obese, have a family history of diabetes, or are not active, and do not eat well. To lower the risk of type 2 diabetes in children - Have them maintain a healthy weight - Be sure they are physically active - Have them eat smaller portions of healthy foods - Limit time with the TV, computer, and video Children and teens with type 1 diabetes may need to take insulin. Type 2 diabetes may be controlled with diet and exercise. If not, patients will need to take oral diabetes medicines or insulin. A blood test called the A1C can check on how you are managing your diabetes.
Doyne honeycomb retinal dystrophy (DHRD) is a condition that affects the eyes and causes vision loss. It is characterized by small, round, white spots known as drusen that accumulate beneath the retinal pigment epithelium (the pigmented layer of the retina). Over time, drusen may grow and come together, creating a honeycomb pattern. It usually begins in early to mid adulthood, but the age of onset varies. The degree of vision loss also varies. DHRD is usually caused by mutations in the EFEMP1 gene and is inherited in an autosomal dominant manner.
Is McCune Albright syndrome inherited? McCune Albright syndrome (MAS) is not inherited. It is caused by a random change (mutation) in the GNAS gene that occurs very early in development. As a result, some of the body's cells have a normal version of the GNAS gene, while other cells have the mutated version. This phenomenon is called mosaicism. The severity of this disorder and its specific features depend on the number and location of cells that have the mutated GNAS gene. This mutation is not passed on to any of the affected individual's children.

Mutations in the RHO, GNAT1, or PDE6B gene cause autosomal dominant congenital stationary night blindness. The proteins produced from these genes are necessary for normal vision, particularly in low-light conditions. These proteins are found in specialized light receptor cells in the retina called rods. Rods transmit visual signals from the eye to the brain when light is dim. The RHO gene provides instructions for making a protein called rhodopsin, which is turned on (activated) by light entering the eye. Rhodopsin then attaches (binds) to and activates the protein produced from the GNAT1 gene, alpha ()-transducin. The -transducin protein then triggers the activation of a protein called cGMP-PDE, which is made up of multiple parts (subunits) including a subunit produced from the PDE6B gene. Activated cGMP-PDE triggers a series of chemical reactions that create electrical signals. These signals are transmitted from rod cells to the brain, where they are interpreted as vision. Mutations in the RHO, GNAT1, or PDE6B gene disrupt the normal signaling that occurs within rod cells. As a result, the rods cannot effectively transmit signals to the brain, leading to a lack of visual perception in low light.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
There is no specific treatment for Sandhoff disease. Supportive treatment includes proper nutrition and hydration and keeping the airway open. Anticonvulsants may initially control seizures.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
What treatments might be available for central core disease? Treatments for central core disease (CCD) depend on the symptoms experienced by each affected individual. When someone is first diagnosed with this condition, a physical examination is done to assess the extent and severity of muscle weakness, and physical therapy and occupational therapy assessments to determine which therapies might be most beneficial. Physical therapy, such as stretching or low-impact exercises, may help improve weakness. Some skeletal abnormalities can be addressed with physical therapy, though others may require surgery. As the muscle weakness and scoliosis associated with CCD can affect breathing, individuals diagnosed with this condition may benefit from pulmonary function tests. If breathing is significantly affected, breathing exercises or other breathing support treatments may be recommended. Another treatment option may be a medication called salbutamol, which was found to significantly increased muscle strength and stamina in six of eight children with CCD.
The symptoms of acute urinary retention may include the following and require immediate medical attention: - inability to urinate - painful, urgent need to urinate - pain or discomfort in the lower abdomen - bloating of the lower abdomen The symptoms of chronic urinary retention may include - urinary frequencyurination eight or more times a day - trouble beginning a urine stream - a weak or an interrupted urine stream - an urgent need to urinate with little success when trying to urinate - feeling the need to urinate after finishing urination - mild and constant discomfort in the lower abdomen and urinary tract Some people with chronic urinary retention may not have symptoms that lead them to seek medical care. People who are unaware they have chronic urinary retention may have a higher chance of developing complications. When to Seek Medical Care A person who has any of the following symptoms should see a health care provider right away: - complete inability to urinate - great discomfort or pain in the lower abdomen and urinary tract
How is hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS) inherited? Hereditary endotheliopathy with retinopathy, nephropathy, and stroke (HERNS) is inherited in an autosomal dominant manner. This means that having a mutation in only one copy of the gene responsible for the condition is sufficient to cause signs and symptoms of HERNS. When an individual with HERNS has children, each child has a 50% (1 in 2) chance to inherit the mutated gene. The term retinal vasculopathy with cerebral leukodystrophy (RVCL) has recently been adopted to include HERNS; cerebroretinal vasculopathy (CRV); and hereditary vascular retinopathy (HVR); historically, these 3 conditions have been considered distinct. However, recent genetic studies have shown that these 3 conditions are likely variations of RVCL and are now known to be caused by mutations in the TREX1 gene.
What are the signs and symptoms of Ausems Wittebol-Post Hennekam syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Ausems Wittebol-Post Hennekam syndrome. 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) Non-midline cleft lip 90% Abnormality of retinal pigmentation 50% Visual impairment 50% 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.
With stroke, treatment depends on the stage of the disease. There are three treatment stages for stroke: prevention, therapy immediately after stroke, and rehabilitation after stroke. Stroke treatments include medications, surgery, and rehabilitation.
What causes Moyamoya disease? In some families, risk for moyamoya disease is inherited. Changes in the RNF213 gene have been associated with the condition. There are other gene changes involved in moyamoya disease, that remain to be found. Factors such as infection or inflammation, likely also play a role in the condition's development in these families. Other people develop moyamoya syndrome or phenomenon. Moyamoya syndrome can occur in association with many different conditions, such as with infections, atherosclerosis (clogged arteries), blood disorders (for example sickle cell disease or beta thalassemia), vasculitis, autoimmune conditions (for example Lupus, thyroid disorders, Sneddon syndrome), connective tissue disorders (for example neurofibromatosis (NF) type 1 or Tuberous sclerosis), chromosome disorders, metabolic diseases, head trauma or radiation, brain tumors, and heart disease, to name a few.
Mutations in the FXN gene cause Friedreich ataxia. This gene provides instructions for making a protein called frataxin. Although its role is not fully understood, frataxin appears to be important for the normal function of mitochondria, the energy-producing centers within cells. One region of the FXN gene contains a segment of DNA known as a GAA trinucleotide repeat. This segment is made up of a series of three DNA building blocks (one guanine and two adenines) that appear multiple times in a row. Normally, this segment is repeated 5 to 33 times within the FXN gene. In people with Friedreich ataxia, the GAA segment is repeated 66 to more than 1,000 times. The length of the GAA trinucleotide repeat appears to be related to the age at which the symptoms of Friedreich ataxia appear. People with GAA segments repeated fewer than 300 times tend to have a later appearance of symptoms (after age 25) than those with larger GAA trinucleotide repeats. The abnormally long GAA trinucleotide repeat disrupts the production of frataxin, which severely reduces the amount of this protein in cells. Certain nerve and muscle cells cannot function properly with a shortage of frataxin, leading to the characteristic signs and symptoms of Friedreich ataxia.

Cystinuria is a condition characterized by the buildup of the amino acid cystine, a building block of most proteins, in the kidneys and bladder. As the kidneys filter blood to create urine, cystine is normally absorbed back into the bloodstream. People with cystinuria cannot properly reabsorb cystine into their bloodstream, so the amino acid accumulates in their urine. As urine becomes more concentrated in the kidneys, the excess cystine forms crystals. Larger crystals become stones that may lodge in the kidneys or in the bladder. Sometimes cystine crystals combine with calcium molecules in the kidneys to form large stones. These crystals and stones can create blockages in the urinary tract and reduce the ability of the kidneys to eliminate waste through urine. The stones also provide sites where bacteria may cause infections.

None of the currently available medications enables people with narcolepsy to consistently maintain a fully normal state of alertness. But EDS and cataplexy, the most disabling symptoms of the disorder, can be controlled in most patients with drug treatment. Often the treatment regimen is modified as symptoms change. Whatever the age of onset, patients find that the symptoms tend to get worse over the two to three decades after the first symptoms appear. Many older patients find that some daytime symptoms decrease in severity after age 60.
Polyglucosan body disease affects the nervous system. Individuals with this condition usually begin to show signs of the disorder after the age of 40. Signs and symptoms include trouble walking due to decreased sensation in the legs (peripheral neuropathy) and muscle weakness and stiffness (spasticity). Individuals may also have trouble controlling bladder function as a result of damage to the nerves of the bladder (neurogenic bladder). Approximately half of the individuals with adult polyglucosan body disease also experience some degree of intellectual impairment. Mutations in the GBE1 gene can cause adult polyglucosan body disease. In some cases, no mutation can be found and the cause of the disease is not known. Adult polyglucosan body disease is thought to be inherited in an autosomal recessive manner. Treatment usually involves a team of specialists who can address the specific symptoms such as walking difficulties, incontinence, and intellectual impairment.
Phosphoglycerate kinase deficiency is caused by mutations in the PGK1 gene. This gene provides instructions for making an enzyme called phosphoglycerate kinase, which is involved in a critical energy-producing process in cells known as glycolysis. During glycolysis, the simple sugar glucose is broken down to produce energy. Mutations in the PGK1 gene reduce the activity of phosphoglycerate kinase, which disrupts energy production and leads to cell damage or cell death. It is unclear why this abnormality preferentially affects red blood cells and brain cells in some people and muscle cells in others. Researchers speculate that different PGK1 gene mutations may have varying effects on the activity of phosphoglycerate kinase in different types of cells.
Sotos syndrome is reported to occur in 1 in 10,000 to 14,000 newborns. Because many of the features of Sotos syndrome can be attributed to other conditions, many cases of this disorder are likely not properly diagnosed, so the true incidence may be closer to 1 in 5,000.
The bronchi are two tubes that branch off the trachea, or windpipe. The bronchi carry air to your lungs. The most common problem with the bronchi is bronchitis, an inflammation of the tubes. Bronchitis can be acute or chronic. Other problems include - Bronchiectasis, a condition in which damage to the airways causes them to widen and become flabby and scarred - Exercise-induced bronchospasm, which happens when the airways shrink while you are exercising - Bronchiolitis, an inflammation of the small airways that branch off from the bronchi - Bronchopulmonary dysplasia, a condition affecting infants Treatment of bronchial disorders depends on the cause.
Hemochromatosis is a condition in which too much iron builds up in the body (iron overload). Accumulation of iron in the organs is toxic and can result in organ failure. While many organs can be affected, it may especially affect the liver, heart, and pancreas. Symptoms of hemochromatosis tend to develop gradually and often don't appear until middle age or later. The condition may not be diagnosed until iron accumulation is excessive. Early symptoms may be vague, such as fatigue or weakness. Other symptoms or features may include joint pain, abdominal pain, loss of sex drive, arthritis, liver disease, diabetes, heart problems, and skin discoloration. Hemochromatosis may be hereditary or acquired (secondary) due to another condition such as anemia, chronic liver disease, or an infection. There is also a neonatal form. Hereditary hemochromatosis is classified by type based on age of onset, genetic cause and mode of inheritance: Hemochromotosis type 1 Hemochromatosis type 2 Hemochromatosis type 3 Hemochromatosis type 4 Treatment usually involves removing blood (phlebotomy), which prevents additional organ damage but does not reverse existing damage.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Neural tube defects are birth defects of the brain, spine, or spinal cord. They happen in the first month of pregnancy, often before a woman even knows that she is pregnant. The two most common neural tube defects are spina bifida and anencephaly. In spina bifida, the fetal spinal column doesn't close completely. There is usually nerve damage that causes at least some paralysis of the legs. In anencephaly, most of the brain and skull do not develop. Babies with anencephaly are usually either stillborn or die shortly after birth. Another type of defect, Chiari malformation, causes the brain tissue to extend into the spinal canal. The exact causes of neural tube defects aren't known. You're at greater risk of having an infant with a neural tube defect if you - Are obese - Have poorly controlled diabetes - Take certain antiseizure medicines Getting enough folic acid, a type of B vitamin, before and during pregnancy prevents most neural tube defects. Neural tube defects are usually diagnosed before the infant is born, through lab or imaging tests. There is no cure for neural tube defects. The nerve damage and loss of function that are present at birth are usually permanent. However, a variety of treatments can sometimes prevent further damage and help with complications.

Most people do not have any symptoms until the hepatitis C virus causes liver damage, which can take 10 or more years to happen. Others may have one or more of the following symptoms: - feeling tired - muscle soreness - upset stomach - stomach pain - fever - loss of appetite - diarrhea - dark-yellow urine - light-colored stools - yellowish eyes and skin, called jaundice When symptoms of hepatitis C occur, they can begin 1 to 3 months after coming into contact with the virus. See a doctor right away if you or a child in your care has symptoms of hepatitis C.
Medications may ease certain symptoms, such as pain. Surgery is the only treatment available to correct functional disturbances or halt the progression of damage to the central nervous system. More than one surgery may be needed to treat the condition. Some CMs have no noticeable symptoms and do not interfere with the person's activities of daily living.
This condition occurs in about 1 in 2,500 newborn girls worldwide, but it is much more common among pregnancies that do not survive to term (miscarriages and stillbirths).
Imerslund-Grsbeck syndrome is a rare condition that was first described in Finland and Norway; in these regions, the condition is estimated to affect 1 in 200,000 people. The condition has also been reported in other countries worldwide; its prevalence in these countries is unknown.
The NINDS conducts and supports research on injuries to the nervous system such as brachial plexus injuries. Much of this research is aimed at finding ways to prevent and treat these disorders.
Osteogenesis imperfecta (OI) is a genetic disorder in which bones break easily. Sometimes the bones break for no known reason. OI can also cause weak muscles, brittle teeth, a curved spine, and hearing loss. OI is caused by one of several genes that aren't working properly. When these genes don't work, it affects how you make collagen, a protein that helps make bones strong. OI can range from mild to severe, and symptoms vary from person to person. A person may have just a few or as many as several hundred fractures in a lifetime. No single test can identify OI. Your doctor uses your medical and family history, physical exam, and imaging and lab tests to diagnose it. Your doctor may also test your collagen (from skin) or genes (from blood). There is no cure, but you can manage symptoms. Treatments include exercise, pain medicine, physical therapy, wheelchairs, braces, and surgery. NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases
Subcortical band heterotopia, also known as double cortex syndrome, is a condition of abnormal brain development that is present from birth. This condition which primarily affects females, occurs when neurons migrate to an area of the brain where they are not supposed to be (heterotopia), and form abnormal areas that appear as band-like clusters of white tissue underneath the gray tissue of the cerebral cortex (subcortical), creating the appearance of a double cortex. Symptoms associated with subcortical band heterotopia vary from severe intellectual disability and epilepsy to normal intelligence with mild or no epilepsy. Subcortical band heterotopia is most often caused by mutations in the DCX gene. The condition is inherited in an X-linked dominant pattern. Some cases may be caused by a small deletion on chromosome 17 involving the LIS1 gene. Management consists of seizure control.
