Pinworms are small parasites that can live in the colon and rectum. You get them when you swallow their eggs. The eggs hatch inside your intestines. While you sleep, the female pinworms leave the intestines through the anus and lay eggs on nearby skin. Pinworms spread easily. When people who are infected touch their anus, the eggs attach to their fingertips. They can spread the eggs to others directly through their hands, or through contaminated clothing, bedding, food, or other articles. The eggs can live on household surfaces for up to 2 weeks. The infection is more common in children. Many people have no symptoms at all. Some people feel itching around the anus or vagina. The itching may become intense, interfere with sleep, and make you irritable. Your health care provider can diagnose pinworm infection by finding the eggs. A common way to collect the eggs is with a sticky piece of clear tape. Mild infections may not need treatment. If you do need medicine, everyone in the household should take it. To prevent becoming infected or reinfected with pinworms, - Bathe after waking up - Wash your pajamas and bed sheets often - Wash your hands regularly, especially after using the bathroom or changing diapers - Change your underwear every day - Avoid nail biting - Avoid scratching the anal area NIH: National Institute of Allergy and Infectious Diseases
Occipital horn syndrome (OHS) is characterized by sagging and non-stretchy skin (cutis laxa), wedge-shaped calcium deposits in a bone at the base of the skull (occipital bone), coarse hair, and loose joints. Individuals with OHS are said to have normal or slightly reduced intelligence. This condition is considered to be a mild type of Menkes diseases, which affects copper levels in the body. Occipital horn syndrome may be caused by mutations in the ATP7A gene, and it is inherited in an x-linked recessive pattern.
Diagnosing osteoporosis involves several steps, starting with a physical exam and a careful medical history, blood and urine tests, and possibly a bone mineral density assessment. When recording information about your medical history, your doctor will ask questions to find out whether you have risk factors for osteoporosis and fractures. The doctor may ask about - any fractures you have had - your lifestyle (including diet, exercise habits, and whether you smoke) - current or past health problems - medications that could contribute to low bone mass and increased fracture risk - your family history of osteoporosis and other diseases - for women, your menstrual history. any fractures you have had your lifestyle (including diet, exercise habits, and whether you smoke) current or past health problems medications that could contribute to low bone mass and increased fracture risk your family history of osteoporosis and other diseases for women, your menstrual history.
A UTI is an infection in the urinary tract. Infections are caused by microbesorganisms too small to be seen without a microscopeincluding fungi, viruses, and bacteria. Bacteria are the most common cause of UTIs. Normally, bacteria that enter the urinary tract are rapidly removed by the body before they cause symptoms. However, sometimes bacteria overcome the bodys natural defenses and cause infection. An infection in the urethra is called urethritis. A bladder infection is called cystitis. Bacteria may travel up the ureters to multiply and infect the kidneys. A kidney infection is called pyelonephritis.
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.
Alpha-1 antitrypsin (AAT) deficiency occurs in all ethnic groups. However, the condition occurs most often in White people of European descent. AAT deficiency is an inherited condition. "Inherited" means the condition is passed from parents to children through genes. If you have bloodline relatives with known AAT deficiency, you're at increased risk for the condition. Even so, it doesn't mean that you'll develop one of the diseases related to the condition. Some risk factors make it more likely that you'll develop lung disease if you have AAT deficiency. Smoking is the leading risk factor for serious lung disease if you have AAT deficiency. Your risk for lung disease also may go up if you're exposed to dust, fumes, or other toxic substances.
How is inclusion body myopathy 2 inherited? Inclusion body myopathy 2 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 causes hereditary cerebral hemorrhage with amyloidosis - Dutch type? The clinical symptoms of hereditary cerebral hemorrhage with amyloidosis - Dutch type are caused by the build-up of a protein called amyloid within the arterial walls of the brain. This protein build-up causes bleeding into the brain. The symptoms occur because bleeding in the brain harms brain tissue. Hereditary cerebral hemorrhage with amyloidosis-Dutch type is an autosomal dominant disorder with complete penetrance (all individuals who inherit the mutated gene will develop the condition). The likely genetic defect is in the amyloid protein precursor protein (APP) gene on chromosome 21.
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.
Arginase deficiency is an inherited disorder that causes the amino acid arginine (a building block of proteins) and ammonia to accumulate gradually in the blood. Ammonia, which is formed when proteins are broken down in the body, is toxic if levels become too high. The nervous system is especially sensitive to the effects of excess ammonia. Arginase deficiency usually becomes evident by about the age of 3. It most often appears as stiffness, especially in the legs, caused by abnormal tensing of the muscles (spasticity). Other symptoms may include slower than normal growth, developmental delay and eventual loss of developmental milestones, intellectual disability, seizures, tremor, and difficulty with balance and coordination (ataxia). Occasionally, high protein meals or stress caused by illness or periods without food (fasting) may cause ammonia to accumulate more quickly in the blood. This rapid increase in ammonia may lead to episodes of irritability, refusal to eat, and vomiting. In some affected individuals, signs and symptoms of arginase deficiency may be less severe, and may not appear until later in life.
Syringomyelia is a rare disorder that causes a cyst to form in your spinal cord. This cyst, called a syrinx, gets bigger and longer over time, destroying part of the spinal cord. Damage to the spinal cord from the syrinx can cause symptoms such as - Pain and weakness in the back, shoulders, arms or legs - Headaches - Inability to feel hot or cold Symptoms vary according to the size and location of the syrinx. They often begin in early adulthood. Syringomyelia usually results from a skull abnormality called a Chiari I malformation. A tumor, meningitis or physical trauma can also cause it. Surgery is the main treatment. Some people also need to have the syrinx drained. Medicines can help ease pain. In some cases, there are no symptoms, so you may not need treatment.

Asthma is a chronic disease that affects your airways. Your airways are tubes that carry air in and out of your lungs. If you have asthma, the inside walls of your airways become sore and swollen. That makes them very sensitive, and they may react strongly to things that you are allergic to or find irritating. When your airways react, they get narrower and your lungs get less air. Symptoms of asthma include - Wheezing - Coughing, especially early in the morning or at night - Chest tightness - Shortness of breath Not all people who have asthma have these symptoms. Having these symptoms doesn't always mean that you have asthma. Your doctor will diagnose asthma based on lung function tests, your medical history, and a physical exam. You may also have allergy tests. When your asthma symptoms become worse than usual, it's called an asthma attack. Severe asthma attacks may require emergency care, and they can be fatal. Asthma is treated with two kinds of medicines: quick-relief medicines to stop asthma symptoms and long-term control medicines to prevent symptoms. NIH: National Heart, Lung, and Blood Institute

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).
Mutations in the HTT gene cause Huntington disease. The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in the brain. The HTT mutation that causes Huntington disease involves a DNA segment known as a CAG trinucleotide repeat. This segment is made up of a series of three DNA building blocks (cytosine, adenine, and guanine) that appear multiple times in a row. Normally, the CAG segment is repeated 10 to 35 times within the gene. In people with Huntington disease, the CAG segment is repeated 36 to more than 120 times. People with 36 to 39 CAG repeats may or may not develop the signs and symptoms of Huntington disease, while people with 40 or more repeats almost always develop the disorder. An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntingtin protein. The elongated protein is cut into smaller, toxic fragments that bind together and accumulate in neurons, disrupting the normal functions of these cells. The dysfunction and eventual death of neurons in certain areas of the brain underlie the signs and symptoms of Huntington disease.
Actin-accumulation myopathy is an autosomal dominant condition, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases are not inherited; they result from new mutations in the gene and occur in people with no history of the disorder in their family.
Pyridoxine-dependent epilepsy is a condition that involves seizures beginning in infancy or, in some cases, before birth. Those affected typically experience prolonged seizures lasting several minutes (status epilepticus). These seizures involve muscle rigidity, convulsions, and loss of consciousness (tonic-clonic seizures). Additional features of pyridoxine-dependent epilepsy include low body temperature (hypothermia), poor muscle tone (dystonia) soon after birth, and irritability before a seizure episode. In rare instances, children with this condition do not have seizures until they are 1 to 3 years old. Anticonvulsant drugs, which are usually given to control seizures, are ineffective in people with pyridoxine-dependent epilepsy. Instead, people with this type of seizure are medically treated with large daily doses of pyridoxine (a type of vitamin B6 found in food). If left untreated, people with this condition can develop severe brain dysfunction (encephalopathy). Even though seizures can be controlled with pyridoxine, neurological problems such as developmental delay and learning disorders may still occur.
SOX2 anophthalmia syndrome is a rare disorder characterized by abnormal development of the eyes and other parts of the body. People with SOX2 anophthalmia syndrome are usually born without eyeballs (anophthalmia), although some individuals have small eyes (microphthalmia). The term anophthalmia is often used interchangeably with severe microphthalmia because individuals with no visible eyeballs typically have some remaining eye tissue. These eye problems can cause significant vision loss. While both eyes are usually affected in SOX2 anophthalmia syndrome, one eye may be more affected than the other. Individuals with SOX2 anophthalmia syndrome may also have seizures, brain abnormalities, slow growth, delayed development of motor skills (such as walking), and mild to severe learning disabilities. Some people with this condition are born with a blocked esophagus (esophageal atresia), which is often accompanied by an abnormal connection between the esophagus and the trachea (tracheoesophageal fistula). Genital abnormalities have been described in affected individuals, especially males. Male genital abnormalities include undescended testes (cryptorchidism) and an unusually small penis (micropenis).
Gout is a common, painful form of arthritis. It causes swollen, red, hot and stiff joints. Gout happens when uric acid builds up in your body. Uric acid comes from the breakdown of substances called purines. Purines are in your body's tissues and in foods, such as liver, dried beans and peas, and anchovies. Normally, uric acid dissolves in the blood. It passes through the kidneys and out of the body in urine. But sometimes uric acid can build up and form needle-like crystals. When they form in your joints, it is very painful. The crystals can also cause kidney stones. Often, gout first attacks your big toe. It can also attack ankles, heels, knees, wrists, fingers, and elbows. At first, gout attacks usually get better in days. Eventually, attacks last longer and happen more often. You are more likely to get gout if you - Are a man - Have family member with gout - Are overweight - Drink alcohol - Eat too many foods rich in purines Gout can be hard to diagnose. Your doctor may take a sample of fluid from an inflamed joint to look for crystals. You can treat gout with medicines. Pseudogout has similar symptoms and is sometimes confused with gout. However, it is caused by calcium phosphate, not uric acid. NIH: National Institute of Arthritis and Musculoskeletal and Skin Diseases
You can seek conventional treatment from a specialized cancer doctor, called an oncologist. The oncologist will usually assemble a team of specialists to guide your therapy. Besides the oncologist, the team may include a surgeon, a radiation oncologist who is a specialist in radiation therapy, and others. Before starting treatment, you may want another doctor to review the diagnosis and treatment plan. Some insurance companies require a second opinion. Others may pay for a second opinion if you request it. You might also be eligible to enroll in a clinical trial to receive treatment that conventional therapies may not offer.
Talipes equinovarus is a congenital (present from birth) condition where the foot turns inward and downward. The cause of this condition is not known, although it may be passed down through families in some cases. This condition occurs in about 1 out of every 1,000 births. Treatment may involve moving the foot into the correct position and using a cast to keep it there. This process is done in small increments over a period of time. In severe cases, surgery may be needed.
Sudden infant death syndrome (SIDS) is the unexpected, sudden death of a child under age 1 which cannot be explained after a thorough investigation is conducted. Infants who are affected by the condition generally appear healthy with no suspicious signs and symptoms prior to the incident. It is the leading cause of death in infants age 1 to 12 months old. The exact underlying cause of SIDS is unknown; however, scientists suspect that it is likely a multifactorial condition (associated with the effects of multiple genes in combination with lifestyle and environmental factors). Although there is no guaranteed way to prevent SIDS, the American Academy of Pediatrics has a published list of recommendations for risk reduction. Please click on the link to access this resource.
The prevalence of leptin receptor deficiency is unknown. It has been estimated to account for up to 3 percent of individuals with severe obesity and hyperphagia that begins in early childhood.
Managed care plans are a type of health insurance. They have contracts with health care providers and medical facilities to provide care for members at reduced costs. These providers make up the plan's network. How much of your care the plan will pay for depends on the network's rules. Plans that restrict your choices usually cost you less. If you want a flexible plan, it will probably cost more. There are three types of managed care plans: - Health Maintenance Organizations (HMO) usually only pay for care within the network. You choose a primary care doctor who coordinates most of your care. - Preferred Provider Organizations (PPO) usually pay more if you get care within the network. They still pay part of the cost if you go outside the network. - Point of Service (POS) plans let you choose between an HMO or a PPO each time you need care.
Heart problems are a complication of anemia and may include - an irregular heartbeat or an unusually fast heartbeat, especially when exercising. - the harmful enlargement of muscles in the heart. - heart failure, which does not mean the heart suddenly stops working. Instead, heart failure is a long-lasting condition in which the heart cant pump enough blood to meet the bodys needs.
Otopalatodigital syndrome type 2 is a rare disorder, affecting fewer than 1 in every 100,000 individuals. Its specific incidence is unknown.
Trisomy 18 occurs in about 1 in 5,000 live-born infants; it is more common in pregnancy, but many affected fetuses do not survive to term. Although women of all ages can have a child with trisomy 18, the chance of having a child with this condition increases as a woman gets older.
What are the signs and symptoms of Parsonage Turner syndrome? Parsonage Turner syndrome is usually characterized by the sudden onset of severe pain in the shoulder and upper arm, which is often described as sharp or throbbing. In some cases, the pain may extend to the neck, lower arm and/or hand on the affected side. Rarely, both sides of the body are involved. Affected people typically experience constant pain that may become worse with movement. Intense pain can last from a few hours to several weeks at which point the pain usually begins to subside; however, mild pain may continue for a year or longer. As the pain subsides, it is typically replaced by progressive (worsening over time) weakness of the affected area, ranging from mild weakness to nearly complete paralysis. Affected people may also experience muscle wasting (atrophy); absent or reduced reflexes; and/or loss of sensation. In some cases, nerves and muscles outside of the shoulder and upper arm region may be affected, as well.
Paraneoplastic syndromes are a group of rare disorders that include paraneoplastic cerebellar degeneration (PCD). Paraneoplastic syndromes are thought to result from an abnormal immune response to an underlying (and often undetected) malignant tumor. PCD is a rare, non-metastatic complication of cancer. PCD is typically thought to be caused by antibodies generated against tumor cells. Instead of just attacking the cancer cells, the cancer-fighting antibodies also attack normal cells in the cerebellum. PCD occurs most often in individuals with the following cancers: ovarian cancer, cancer of the uterus, breast cancer, small-cell lung cancer, and Hodgkin lymphoma. Symptoms of PCD may include dizziness, loss of coordination, blurred vision, nystagmus, ataxia, and speech difficulties.
At least 500 cases of 22q13.3 deletion syndrome are known.
How might Kuskokwim disease be treated? Treatment for Kuskokwim disease depends on the nature and severity of signs and symptoms in each affected individual. There is currently no completely successful approach to treat arthrogryposis. The goals of treatment may include lower-limb alignment, establishing stability for ambulation (moving about) and improving upper-limb function for self-care. Many individuals with Kuskokwim disease are treated with leg braces and/or surgery and eventually are able to walk upright.
Sheldon-Hall syndrome can be caused by mutations in the MYH3, TNNI2, TNNT3, or TPM2 gene. These genes provide instructions for making proteins that are involved in muscle tensing (contraction). Muscle contraction occurs when thick filaments made of proteins called myosins slide past thin filaments made of proteins called actins. The MYH3 gene provides instructions for making a myosin protein that is normally active only before birth and is important for early development of the muscles. The process of muscle contraction is controlled (regulated) by other proteins called troponins and tropomyosins, which affect the interaction of myosin and actin. Certain troponin proteins are produced from the TNNI2 and TNNT3 genes. The TPM2 gene provides instructions for making a tropomyosin protein. Mutations in the MYH3, TNNI2, TNNT3, or TPM2 gene likely interfere with normal muscle development or prevent muscle contractions from being properly controlled, resulting in the contractures and other muscle and skeletal abnormalities associated with Sheldon-Hall syndrome. It is unknown why the contractures mainly affect the hands and feet or how these gene mutations are related to other features of this disorder.
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.
The treatment for kidney stones usually depends on their size and what they are made of. Kidney stones may be treated by your regular doctor or by a urologista doctor who specializes in the urinary tract. You may need treatment if you have symptoms or if a kidney stone is blocking your urinary tract. Small stones dont usually need treatment. Still, you may need pain medicine. You should also drink lots of fluids to help move the stone along. If you are vomiting often or dont drink enough fluids, you may need to go to the hospital and get fluids through a needle in your arm. If you have a large kidney stone or your urinary tract is blocked, the urologist can remove the stone or break it into small pieces with the following treatments:
What treatment is available for coccygodynia? Treatment for coccygodynia generally falls into conservative management or surgical intervention categories. The conservative approach typically includes hot sitz baths, NSAIDs, stool softeners, and/or the use of a donut-shaped pillow or gel cushion to descrease pressure and irritation of the coccyx. If these treatment options fails, glucocorticoid injections may be used in an attempt to reduce the pain. Massage therapy has also been used to help decrease pain, but most studies have shown that the relief experienced from this form of therapy is temporary. The more aggressive and rare approach involves either partial or complete removal of the coccyx (coccygectomy).
Bednar tumor is a rare variant of dermatofibrosarcoma protuberans (DFSP), a soft tissue sarcoma that develops in the deep layers of the skin. It accounts for approximately 1% of all DFSP cases. Bednar tumor is also known as pigmented DFSP because it contains dark-colored cells that give may give the tumor a multi-colored (i.e red and brown) appearance. The tumor may begin as a painless, slow-growing papule or patch of skin; however, accelerated growth, bleeding and/or pain are often observed as it grows. The underlying cause of Bednar tumor is unknown. There is currently no evidence of an inherited risk for the condition and most cases occur sporadically in people with no family history of the condition. Treatment varies based on the severity of the condition, the location of the tumor and the overall health of the affected person. The tumor is generally treated with surgery. In advanced cases, radiation therapy and/or systemic therapy may be recommended, as well.
Learning about different treatments for kidney failure will help you choose the one that best fits your lifestyle. Talk with your doctor and people on hemodialysis or peritoneal dialysis to learn about the pros and cons of each treatment. Ask your doctor about the transplant waiting list and about medicines required after a transplant. Talk with people who have had kidney transplants and ask how it has changed their lives. If you plan to keep working, think about which treatment can help make that easier. If spending time with family and friends means a lot to you, learn about which treatment may give you the most free time. Find out which treatment will give you the best chance to be healthy and live longer. Talking with your doctor ahead of time about your options can help you take control of your care. Understanding the treatment you choose and getting used to the idea that you will be receiving this treatment takes time. If you choose one type of dialysis treatment and find it is not a good fit for your life, talk with your doctor about selecting another type of dialysis treatment that better meets your needs. While kidney failure can make your life harder, treatments can help improve your life.
Tularemia is an infection common in wild rodents caused by the bacterium Francisella tularensis. It is transmitted to humans by contact with infected animal tissues or by ticks, biting flies, and mosquitoes. The condition is most common in North America and parts of Europe and Asia. It is very rare in the United States. The illness, which is characterized by fever, chills, headache, joint pain and muscle weakness, may continue for several weeks after symptoms begin. Streptomycin and tetracycline are commonly used to treat the infection.
Crouzon syndrome is a genetic disorder characterized by the premature fusion of certain skull bones (craniosynostosis). This early fusion prevents the skull from growing normally and affects the shape of the head and face. Many features of Crouzon syndrome result from the premature fusion of the skull bones. Abnormal growth of these bones leads to wide-set, bulging eyes and vision problems caused by shallow eye sockets; eyes that do not point in the same direction (strabismus); a beaked nose; and an underdeveloped upper jaw. In addition, people with Crouzon syndrome may have dental problems and hearing loss, which is sometimes accompanied by narrow ear canals. A few people with Crouzon syndrome have an opening in the lip and the roof of the mouth (cleft lip and palate). The severity of these signs and symptoms varies among affected people. People with Crouzon syndrome are usually of normal intelligence.
People who have innocent (harmless) heart murmurs don't have any signs or symptoms other than the murmur itself. This is because innocent heart murmurs aren't caused by heart problems. People who have abnormal heart murmurs may have signs or symptoms of the heart problems causing the murmurs. These signs and symptoms may include: Poor eating and failure to grow normally (in infants) Shortness of breath, which may occur only with physical exertion Excessive sweating with minimal or no exertion Chest pain Dizziness or fainting A bluish color on the skin, especially on the fingertips and lips Chronic cough Swelling or sudden weight gain Enlarged liver Enlarged neck veins Signs and symptoms depend on the problem causing the heart murmur and its severity.
What causes Merkel cell carcinoma? The exact underlying cause of Merkel cell carcinoma (MCC) is unknown, but several risk factors have been associated with the development of MCC. Having one or more risk factors does not mean that a person will develop MCC; most individuals with risk factors will not develop MCC. Risk factors include: -being over 50 years of age -having fair skin -having a history of extensive sun exposure (natural or artificial) -having chronic immune suppression, such as after organ transplantation or having HIV Researchers have also found that a virus called Merkel cell polyomavirus (MCPyV) is frequently involved in the development of MCC. MCPyV is found in about 80% of tumor cells tested. This virus is thought to alter the DNA in such a way that influences tumor development.
Acute zonal occult outer retinopathy (AZOOR) is a rare condition that affects the eyes. People with this condition may experience a sudden onset of photopsia (the presence of perceived flashes of light) and an area of partial vision loss (a blindspot). Other symptoms may include "whitening of vision" or blurred vision. Although anyone can be affected, the condition is most commonly diagnosed in young women (average age 36.7 years). The underlying cause of AZOOR is currently unknown; however, some researchers have proposed that infectious agents (such as viruses) or autoimmunity may play a role in the development of the condition. No treatment has been proven to improve the visual outcome of AZOOR; however, systemic corticosteroids are the most commonly used therapy.
Warts are growths on your skin caused by an infection with humanpapilloma virus, or HPV. Types of warts include - Common warts, which often appear on your fingers - Plantar warts, which show up on the soles of your feet - Genital warts, which are a sexually transmitted disease - Flat warts, which appear in places you shave frequently In children, warts often go away on their own. In adults, they tend to stay. If they hurt or bother you, or if they multiply, you can remove them. Chemical skin treatments usually work. If not, various freezing, surgical and laser treatments can remove warts.
How is Buerger disease treated? Currently there is not a cure for Buerger disease, however there are treatments that can help control it. The most essential part of treatment is to avoid all tobacco and nicotine products. Even one cigarette a day can worsen the disease. A doctor can help a person with Buerger disease learn about safe medications and programs to combat smoking/nicotine addiction. Continued smoking is associated with an overall amputation rate of 40 to 50 percent. The following treatments may also be helpful, but do not replace smoking/nicotine cessation: Medications to dilate blood vessels and improve blood flow (e.g., intravenous Iloprost) Medications to dissolve blood clots Treatment with calcium channel blockers Walking exercises Intermittent compression of the arms and legs to increase blood flow to your extremities Surgical sympathectomy (a controversial surgery to cut the nerves to the affected area to control pain and increase blood flow) Therapeutic angiogenesis (medications to stimulate growth of new blood vessels) Spinal cord stimulation Amputation, if infection or gangrene occurs
Juvenile retinoschisis is an eye condition characterized by impaired vision that begins in childhood and occurs almost exclusively in males. The condition affects the retina, which is a specialized light-sensitive tissue that lines the back of the eye. This affects the sharpness of vision. Central vision is more commonly affected. Vision often deteriorates early in life, but then usually becomes stable until late adulthood. A second decline in vision typically occurs in a man's fifties or sixties. Sometimes severe complications occur, including separation of the retinal layers (retinal detachment) or leakage of blood vessels in the retina (vitreous hemorrhage). These can lead to blindness. Juvenile retinoschisis is caused by mutations in the RS1 gene. It is inherited in an X-linked recessive pattern. Low-vision aids can be helpful. Surgery may be needed for some complications.
Limb-girdle muscular dystrophy type 2I (LGMD2I) is a form of limb-girdle muscular dystrophy, which refers to a group of conditions that cause weakness and wasting of the muscles in the arms and legs. The proximal muscles (those closest to the body such as the upper arms and thighs) are generally most affected by the condition. In LGMD2I, specifically, signs and symptoms often develop in late childhood (average age 11.5 years) and may include difficulty running and walking. The symptoms gradually worsen overtime and affected people generally rely on a wheelchair for mobility approximately 23-26 years after onset. LGMD2I is caused by changes (mutations) in the FKRP gene and is inherited in an autosomal recessive manner. There is, unfortunately, no cure for LGMD2I and treatment is based on the signs and symptoms present in each person.
MCKD1 is caused by mutations in the MUC1 gene. This gene provides instructions for making a protein called mucin 1, which is one of several mucin proteins that make up mucus. Mucus is a slippery substance that lubricates the lining of the airways, digestive system, reproductive system, and other organs and tissues and protects them from foreign invaders and other particles. In addition to its role in mucus, mucin 1 relays signals from outside the cell to the cell's nucleus. Through this cellular signaling, mucin 1 is thought to be involved in the growth, movement, and survival of cells. Research suggests that mucin 1 plays a role in the normal development of the kidneys. MCKD1 is caused by the insertion of a single DNA building block (nucleotide) called cytosine into the MUC1 gene. These mutations have been found in one particular region of the gene. They lead to the production of an altered protein. It is unclear how this change causes kidney disease.
How might Behr syndrome be treated? Treatment is symptomatic. For instance, people who develop muscle contractures may have to undergo surgery.
Treatment is symptomatic and supportive and may include occupational and speech therapy, and "cueing" or other forms of communication such as using pictures and hand gestures. Many children with the disorder require special education.
Restless legs syndrome (RLS) is a neurological disorder characterized by unpleasant sensations in the legs and an uncontrollable, and sometimes overwhelming, urge to move them for relief. Individuals affected with the disorder often describe the sensations as throbbing, polling, or creeping. The sensations range in severity from uncomfortable to irritating to painful.

Whipworm is a soil-transmitted helminth (STH) and is the third most common roundworm of humans. Whipworm causes an infection called trichuriasis and often occurs in areas where human feces is used as fertilizer or where defecation onto soil happens. The worms are spread from person to person by fecal-oral transmission or through feces-contaminated food. Geographic Distribution Worldwide, infection occurs more frequently in areas with tropical weather and poor sanitation practices, and among children. In 2002, the estimated number of persons infected with whipworm was 1 billion. Trichuriasis also occurs in the southern United States.
X-linked chondrodysplasia punctata 1 is caused by genetic changes involving the ARSE gene. This gene provides instructions for making an enzyme called arylsulfatase E. The function of this enzyme is unknown, although it appears to be important for normal skeletal development and is thought to participate in a chemical pathway involving vitamin K. Evidence suggests that vitamin K normally plays a role in bone growth and maintenance of bone density. Between 60 and 75 percent of males with the characteristic features of X-linked chondrodysplasia punctata 1 have a mutation in the ARSE gene. These mutations reduce or eliminate the function of arylsulfatase E. Another 25 percent of affected males have a small deletion of genetic material from the region of the X chromosome that contains the ARSE gene. These individuals are missing the entire gene, so their cells produce no functional arylsulfatase E. Researchers are working to determine how a shortage of arylsulfatase E disrupts the development of bones and cartilage and leads to the characteristic features of X-linked chondrodysplasia punctata 1. Some people with the features of X-linked chondrodysplasia punctata 1 do not have an identified mutation in the ARSE gene or a deletion involving the gene. Other, as-yet-unidentified genetic and environmental factors may also be involved in causing this disorder.
The National Institute of Neurological Disorders and Stroke (NINDS) conducts stroke research and clinical trials at its laboratories and clinics at the National Institutes of Health (NIH) and through grants to major medical institutions across the country. Scientists are currently studying different drugs to reduce cognitive problems seen in patients with CADASIL. Researchers are also looking at ways to overcome an over-reaction to hormones that lead to high blood pressure and poor blood supply in patients with CADASIL.
Mutations in the PHOX2B gene cause CCHS. The PHOX2B gene provides instructions for making a protein that acts early in development to help promote the formation of nerve cells (neurons) and regulate the process by which the neurons mature to carry out specific functions (differentiation). The protein is active in the neural crest, which is a group of cells in the early embryo that give rise to many tissues and organs. Neural crest cells migrate to form parts of the autonomic nervous system, many tissues in the face and skull, and other tissue and cell types. Mutations are believed to interfere with the PHOX2B protein's role in promoting neuron formation and differentiation, especially in the autonomic nervous system, resulting in the problems regulating breathing and other body functions that occur in CCHS.
Most symptoms of Wernicke's encephalopathy can be reversed if detected and treated promptly and completely. Stopping alcohol use may prevent further nerve and brain damage. However, improvement in memory function is slow and, usually, incomplete. Without treatment, these disorders can be disabling and life-threatening.
Although essential tremor is not life-threatening, it can make it harder to perform daily tasks and is embarrassing to some people. Tremor frequency may decrease as the person ages, but the severity may increase, affecting the person's ability to perform certain tasks or activities of daily living. In many people the tremor may be mild throughout life.
How might Coffin-Siris syndrome be treated? People with Coffin-Siris syndrome may benefit from occupational, physical, and speech therapy. Developmental pediatricians may be helpful in recommending and coordinating therapeutic and educational interventions. Additional specialty care may be needed depending on the symptoms in the individual, such as by gastrointestinal, eye, kidney, heart, and hearing specialists.
How might iridocorneal endothelial (ICE) syndrome be treated? It is not possible to halt the progression of ICE syndrome. Treatment is usually focused on managing the glaucoma associated with the disease, either through medication or possible surgery, to help reduce pressure in the eye. Medication and corneal transplant can also be used to treat corneal swelling.
About 60 percent of all cases of Bannayan-Riley-Ruvalcaba syndrome result from mutations in the PTEN gene. Another 10 percent of cases are caused by a large deletion of genetic material that includes part or all of this gene. The protein produced from the PTEN gene is a tumor suppressor, which means that it normally prevents cells from growing and dividing (proliferating) too rapidly or in an uncontrolled way. If this protein is missing or defective, cell proliferation is not regulated effectively. Uncontrolled cell division can lead to the formation of hamartomas and other cancerous and noncancerous tumors. The protein produced from the PTEN gene likely has other important functions within cells; however, it is unclear how mutations in this gene can cause the other features of Bannayan-Riley-Ruvalcaba syndrome, such as macrocephaly, developmental delay, and muscle and skeletal abnormalities. When Bannayan-Riley-Ruvalcaba syndrome is not caused by mutations or deletions of the PTEN gene, the cause of the condition is unknown.
Signs of gastrointestinal stromal tumors include blood in the stool or vomit. These and other signs and symptoms may be caused by a GIST or by other conditions. Check with your doctor if you have any of the following: - Blood (either bright red or very dark) in the stool or vomit. - Pain in the abdomen, which may be severe. - Feeling very tired. - Trouble or pain when swallowing. - Feeling full after only a little food is eaten.

Chromosomes are the structures found in every cell of the body that contain our DNA, the instructions that tell our body what to do. Humans have 23 pairs of chromosomes, which means that each human cell contains 46 chromosomes. Each chromosome has a p and q arm; p is the short arm and q is the long arm. The p arm is always on the top and the q arm is on the bottom. Chromosome 9 inversion is when there are two breaks on chromosome 9. The segment between the breakpoints flips around and reinserts back into the same place on chromosome 9. If both breaks occur in the same arm of the chromosome, this is called a paracentric inversion. If one break occurs in the short arm and the other in the long arm of the chromosome, then this is called a pericentric inversion. Chromosome 9 inversions commonly occur as a pericentric inversion.
Weissenbacher-Zweymller syndrome is very rare; only a few families with the disorder have been reported worldwide.
Thrombotic thrombocytopenic purpura (TTP), congenital is a blood disorder characterized by low platelets (i.e., thrombocytopenia), small areas of bleeding under the skin (i.e., purpura), low red blood cell count, and hemolytic anemia. TTP causes blood clots (thrombi) to form in small blood vessels throughout the body. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart. Resulting complications can include neurological problems (such as personality changes, headaches, confusion, and slurred speech), fever, abnormal kidney function, abdominal pain, and heart problems. Hemolytic anemia can lead to paleness, yellowing of the eyes and skin (jaundice), fatigue, shortness of breath, and a rapid heart rate. TTP, congenital is much rarer than the acquired form and typically appears in infancy or early childhood. Signs and symptoms often recur on a regular basis. TTP, congenital results from mutations in the ADAMTS13 gene. The condition is inherited in an autosomal recessive manner.
How is harlequin ichthyosis inherited? Harlequin ichthyosis 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.
How might idiopathic juxtafoveal retinal telangiectasia (IJT) be treated? Laser photocoagulation of areas of leakage may be helpful in treating vision loss in people with certain subtypes of IJT, such as Group 1A. A laser is a powerful beam of light which can be focused on the retina. Small "bursts" of the laser can be used to seal leaky blood vessels, destroy abnormal blood vessels, seal retinal tears, and destroy abnormal tissue in the back of the eye. Photocoagulation usually is not considered for people with people in Group 1B because of the closeness of the leakage to the fovea, and the good prognosis without treatment. It may benefit people in Group 2 but in most cases, the abnormal lesions are so close to the fovea that treatment is difficult.
GM1 gangliosidosis is estimated to occur in 1 in 100,000 to 200,000 newborns. Type I is reported more frequently than the other forms of this condition. Most individuals with type III are of Japanese descent.
What are the signs and symptoms of Cranioacrofacial syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Cranioacrofacial 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) Abnormal hand morphology - Autosomal dominant inheritance - Dupuytren contracture - Narrow face - Pulmonic stenosis - Ventricular septal defect - 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.
Because there is no way to tell whether symptoms are from a TIA or an acute stroke, patients should assume that all stroke-like symptoms signal an emergency and should not wait to see if they go away. A prompt evaluation (within 60 minutes) is necessary to identify the cause of the TIA and determine appropriate therapy. Depending on a patient's medical history and the results of a medical examination, the doctor may recommend drug therapy or surgery to reduce the risk of stroke in people who have had a TIA. The use of antiplatelet agents, particularly aspirin, is a standard treatment for patients at risk for stroke. People with atrial fibrillation (irregular beating of the heart) may be prescribed anticoagulants.

Rett syndrome is a brain disorder that occurs almost exclusively in girls. The most common form of the condition is known as classic Rett syndrome. After birth, girls with classic Rett syndrome have 6 to 18 months of apparently normal development before developing severe problems with language and communication, learning, coordination, and other brain functions. Early in childhood, affected girls lose purposeful use of their hands and begin making repeated hand wringing, washing, or clapping motions. They tend to grow more slowly than other children and have a small head size (microcephaly). Other signs and symptoms that can develop include breathing abnormalities, seizures, an abnormal side-to-side curvature of the spine (scoliosis), and sleep disturbances. Researchers have described several variant or atypical forms of Rett syndrome, which can be milder or more severe than the classic form.
Febrile ulceronecrotic Mucha-Habermann disease (FUMHD) is a rare and severe form of pityriasis lichenoides et varioliformis acuta (PLEVA). PLEVA is characterized by skin lesions that ulcerate, breakdown, form open sores, then form a red-brown crust. FUMHD often begins as PLEVA, but then rapidly and suddenly progresses to large, destructive ulcers. There may be fever and extensive, painful loss of skin tissue as well as secondary infection of the ulcers. Diagnosis of FUMHD is confirmed by biopsy of skin lesions. FUMHD occurs more frequently in children, peaking at age 5 to 10. Males tend to be affected more often than females. While some cases of FUMHD have resolved without therapy, others have resulted in death. Early diagnosis and prompt treatment may help to reduce morbidity and death.

SLE and other autoimmune disorders tend to run in families, but the inheritance pattern is usually unknown. People may inherit a gene variation that increases or decreases the risk of SLE, but in most cases do not inherit the condition itself. Not all people with SLE have a gene variation that increases the risk, and not all people with such a gene variation will develop the disorder. In rare cases, SLE can be 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.

A scar is a permanent patch of skin that grows over a wound. It forms when your body heals itself after a cut, scrape, burn, or sore. You can also get scars from surgery that cuts through the skin, infections like chickenpox, or skin conditions like acne. Scars are often thicker, as well as pinker, redder, or shinier, than the rest of your skin. How your scar looks depends on - How big and deep your wound is - Where it is - How long it takes to heal - Your age - Your inherited tendency to scar Scars usually fade over time but never go away completely. If the way a scar looks bothers you, various treatments might minimize it. These include surgical revision, dermabrasion, laser treatments, injections, chemical peels, and creams.
Thanatophoric dysplasia is a severe skeletal disorder characterized by extremely short limbs and folds of extra (redundant) skin on the arms and legs. Other features of this condition include a narrow chest, short ribs, underdeveloped lungs, and an enlarged head with a large forehead and prominent, wide-spaced eyes. Researchers have described two major forms of thanatophoric dysplasia, type I and type II. Type I thanatophoric dysplasia is distinguished by the presence of curved thigh bones and flattened bones of the spine (platyspondyly). Type II thanatophoric dysplasia is characterized by straight thigh bones and a moderate to severe skull abnormality called a cloverleaf skull. The term thanatophoric is Greek for "death bearing." Infants with thanatophoric dysplasia are usually stillborn or die shortly after birth from respiratory failure; however, a few affected individuals have survived into childhood with extensive medical help.
Adermatoglyphia is inherited in an autosomal dominant pattern, which means one copy of the altered SMARCAD1 gene in each cell is sufficient to cause the condition. In many cases, an affected person has one parent with the condition.
Dementia is a loss of thinking, remembering, and reasoning skills that interferes with a persons daily life and activities. Alzheimers disease is the most common cause of dementia among older people. Dementia ranges in severity from the mild stage, when it is just beginning to affect a persons functioning, to the severe stage, when the person must depend completely on others for care.
The prevalence of rippling muscle disease is unknown.
Mutations in the ATM gene cause ataxia-telangiectasia. The ATM gene provides instructions for making a protein that helps control cell division and is involved in DNA repair. This protein plays an important role in the normal development and activity of several body systems, including the nervous system and immune system. The ATM protein assists cells in recognizing damaged or broken DNA strands and coordinates DNA repair by activating enzymes that fix the broken strands. Efficient repair of damaged DNA strands helps maintain the stability of the cell's genetic information. Mutations in the ATM gene reduce or eliminate the function of the ATM protein. Without this protein, cells become unstable and die. Cells in the part of the brain involved in coordinating movements (the cerebellum) are particularly affected by loss of the ATM protein. The loss of these brain cells causes some of the movement problems characteristic of ataxia-telangiectasia. Mutations in the ATM gene also prevent cells from responding correctly to DNA damage, which allows breaks in DNA strands to accumulate and can lead to the formation of cancerous tumors.
HLRCC has been reported in approximately 100 families worldwide. Its prevalence is unknown.
Currently, only central core disease has an effective treatment (see above). There are no known cures for any of these disorders. Supportive treatment may involve orthopedic treatments, as well as physical, occupational or speech therapy.
What causes Townes-Brocks syndrome? Townes-Brocks syndrome is caused by mutations in the SALL1 gene. This gene is part of a group of genes called the SALL family. These genes provide instructions for making proteins that are involved in the formation of tissues and organs before birth. SALL proteins act as transcription factors, which means they attach (bind) to specific regions of DNA and help control the activity of particular genes. Some mutations in the SALL1 gene lead to the production of an abnormally short version of the SALL1 protein that malfunctions within the cell. Other mutations prevent one copy of the gene in each cell from making any protein. It is unclear how these genetic changes disrupt normal development and cause the symptoms associated with Townes-Brocks syndrome.

Iron-refractory iron deficiency anemia is one of many types of anemia, which is a group of conditions characterized by a shortage of healthy red blood cells. This shortage prevents the blood from carrying an adequate supply of oxygen to the body's tissues. Iron-refractory iron deficiency anemia results from an inadequate amount (deficiency) of iron in the bloodstream. It is described as "iron-refractory" because the condition is totally resistant (refractory) to treatment with iron given orally and partially resistant to iron given in other ways, such as intravenously (by IV). In people with this form of anemia, red blood cells are abnormally small (microcytic) and pale (hypochromic). The symptoms of iron-refractory iron deficiency anemia can include tiredness (fatigue), weakness, pale skin, and other complications. These symptoms are most pronounced during childhood, although they tend to be mild. Affected individuals usually have normal growth and development.
Hemophilia is a bleeding disorder that slows the blood clotting process. People with this condition experience prolonged bleeding or oozing following an injury, surgery, or having a tooth pulled. In severe cases of hemophilia, continuous bleeding occurs after minor trauma or even in the absence of injury (spontaneous bleeding). Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. Milder forms of hemophilia do not necessarily involve spontaneous bleeding, and the condition may not become apparent until abnormal bleeding occurs following surgery or a serious injury. The major types of this condition are hemophilia A (also known as classic hemophilia or factor VIII deficiency) and hemophilia B (also known as Christmas disease or factor IX deficiency). Although the two types have very similar signs and symptoms, they are caused by mutations in different genes. People with an unusual form of hemophilia B, known as hemophilia B Leyden, experience episodes of excessive bleeding in childhood but have few bleeding problems after puberty.

Cant syndrome is a rare condition. About three dozen affected individuals have been reported in the medical literature.
Voice is the sound made by air passing from your lungs through your larynx, or voice box. In your larynx are your vocal cords, two bands of muscle that vibrate to make sound. For most of us, our voices play a big part in who we are, what we do, and how we communicate. Like fingerprints, each person's voice is unique. Many things we do can injure our vocal cords. Talking too much, screaming, constantly clearing your throat, or smoking can make you hoarse. They can also lead to problems such as nodules, polyps, and sores on the vocal cords. Other causes of voice disorders include infections, upward movement of stomach acids into the throat, growths due to a virus, cancer, and diseases that paralyze the vocal cords. Signs that your voice isn't healthy include - Your voice has become hoarse or raspy - You've lost the ability to hit some high notes when singing - Your voice suddenly sounds deeper - Your throat often feels raw, achy, or strained - It's become an effort to talk Treatment for voice disorders varies depending on the cause. Most voice problems can be successfully treated when diagnosed early. NIH: National Institute on Deafness and Other Communication Disorders
Gray platelet syndrome is a bleeding disorder associated with abnormal platelets, which are blood cell fragments involved in blood clotting. People with this condition tend to bruise easily and have an increased risk of nosebleeds (epistaxis). They may also experience abnormally heavy or extended bleeding following surgery, dental work, or minor trauma. Women with gray platelet syndrome often have irregular, heavy periods (menometrorrhagia). These bleeding problems are usually mild to moderate, but they have been life-threatening in a few affected individuals. A condition called myelofibrosis, which is a buildup of scar tissue (fibrosis) in the bone marrow, is another common feature of gray platelet syndrome. Bone marrow is the spongy tissue in the center of long bones that produces most of the blood cells the body needs, including platelets. The scarring associated with myelofibrosis damages bone marrow, preventing it from making enough blood cells. Other organs, particularly the spleen, start producing more blood cells to compensate; this process often leads to an enlarged spleen (splenomegaly).
Dopamine -hydroxylase deficiency is a very rare disorder. Fewer than 20 affected individuals, all of Western European descent, have been described in the scientific literature.
Washing your hands frequently can help prevent upper respiratory infections, which can lead to an ear infection called otitis media. The ear infection otitis media can be a cause of long-term hearing loss. Also, ask your doctor about a yearly flu shot to help prevent flu-related ear infections. If you still get an ear infection, see a doctor immediately before it becomes more serious.
Froelich syndrome is characterized by obesity and hypogonadism due to a hypothalamic-pituitary disorder. The hypothalamus is a part of the brain where certain functions such as sleep cycles and body temperature are regulated. The pituitary is a gland that makes hormones that affect growth and the functions of other glands in the body. Froehlich syndrome is acquired (i.e., not thought to be inherited or genetic). This syndrome appears to affect males more commonly. The term 'Froelich syndrome' is rarely used today.
Nephrotic syndrome can be caused by diseases that affect only the kidneys, such as focal segmental glomerulosclerosis (FSGS) or membranous nephropathy. Diseases that affect only the kidneys are called primary causes of nephrotic syndrome. The glomeruli are usually the targets of these diseases for reasons that are not fully understood. In FSGSthe most common primary cause of nephrotic syndromescar tissue forms in parts of the glomeruli. In membranous nephropathy, immune molecules form harmful deposits on the glomeruli. Nephrotic syndrome can also be caused by systemic diseases, which are diseases that affect many parts of the body, such as diabetes or lupus. Systemic diseases that affect the kidneys are called secondary causes of nephrotic syndrome. More than 50 percent of nephrotic syndrome cases in adults have secondary causes, with diabetes being the most common.1
