Question: What is (are) 3-methylglutaconyl-CoA hydratase deficiency ?

Answer: 3-methylglutaconyl-CoA hydratase deficiency is an inherited condition that causes neurological problems. Beginning in infancy to early childhood, children with this condition often have delayed development of mental and motor skills (psychomotor delay), speech delay, involuntary muscle cramping (dystonia), and spasms and weakness of the arms and legs (spastic quadriparesis). Affected individuals can also have optic atrophy, which is the degeneration (atrophy) of nerve cells that carry visual information from the eyes to the brain.  In some cases, signs and symptoms of 3-methylglutaconyl-CoA hydratase deficiency begin in adulthood, often in a person's twenties or thirties. These individuals have damage to a type of brain tissue called white matter (leukoencephalopathy), which likely contributes to progressive problems with speech (dysarthria), difficulty coordinating movements (ataxia), stiffness (spasticity), optic atrophy, and a decline in intellectual function (dementia).  Affected individuals who show symptoms of 3-methylglutaconyl-CoA hydratase deficiency in childhood often go on to develop leukoencephalopathy and other neurological problems in adulthood.  All people with 3-methylglutaconyl-CoA hydratase deficiency accumulate large amounts of a substance called 3-methylglutaconic acid in their body fluids. As a result, they have elevated levels of acid in their blood (metabolic acidosis) and excrete large amounts of acid in their urine (aciduria). 3-methylglutaconyl-CoA hydratase deficiency is one of a group of metabolic disorders that can be diagnosed by the presence of increased levels 3-methylglutaconic acid in urine (3-methylglutaconic aciduria). People with 3-methylglutaconyl-CoA hydratase deficiency also have high urine levels of another acid called 3-methylglutaric acid.
Question: What is (are) isolated lissencephaly sequence ?

Answer: Isolated lissencephaly sequence (ILS) is a condition that affects brain development before birth. Normally, the cells that make up the exterior of the brain (cerebral cortex) are well-organized, multi-layered, and arranged into many folds and grooves (gyri). In people with ILS, the cells of the cerebral cortex are disorganized, and the brain surface is abnormally smooth with an absence (agyria) or reduction (pachygyria) of folds and grooves. In most cases, these abnormalities impair brain growth, causing the brain to be smaller than normal (microcephaly). This underdevelopment of the brain causes severe intellectual disability, delayed development, and recurrent seizures (epilepsy) in individuals with ILS.  More than 90 percent of individuals with ILS develop epilepsy, often within the first year of life. Up to 80 percent of infants with ILS have a type of seizure called infantile spasms, these seizures can be severe enough to cause brain dysfunction (epileptic encephalopathy). After the first months of life, most children with ILS develop a variety of seizure types, including persisting infantile spasms, short periods of loss of consciousness (absence seizures); sudden episodes of weak muscle tone (drop attacks); rapid, uncontrolled muscle jerks (myoclonic seizures); and episodes of muscle rigidity, convulsions, and loss of consciousness (tonic-clonic seizures).  Infants with ILS may have poor muscle tone (hypotonia) and difficulty feeding, which leads to poor growth overall. Hypotonia also affects the muscles used for breathing, which often causes breathing problems that can lead to a life-threatening bacterial lung infection known as aspiration pneumonia. Children with ILS often develop muscle stiffness (spasticity) in their arms and legs and an abnormal side-to-side curvature of the spine (scoliosis). Rarely, the muscle stiffness will progress to paralysis (spastic paraplegia). Individuals with ILS cannot walk and rarely crawl. Most children with ILS do not develop communication skills.
Question: What are the genetic changes related to Gilbert syndrome ?

Answer: Changes in the UGT1A1 gene cause Gilbert syndrome. This gene provides instructions for making the bilirubin uridine diphosphate glucuronosyltransferase (bilirubin-UGT) enzyme, which is found primarily in liver cells and is necessary for the removal of bilirubin from the body.  The bilirubin-UGT enzyme performs a chemical reaction called glucuronidation. During this reaction, the enzyme transfers a compound called glucuronic acid to unconjugated bilirubin, converting it to conjugated bilirubin. Glucuronidation makes bilirubin dissolvable in water so that it can be removed from the body.  Gilbert syndrome occurs worldwide, but some mutations occur more often in particular populations. In many populations, the most common genetic change that causes Gilbert syndrome (known as UGT1A1*28) occurs in an area near the UGT1A1 gene called the promoter region, which controls the production of the bilirubin-UGT enzyme. This genetic change impairs enzyme production. However, this change is uncommon in Asian populations, and affected Asians often have a mutation that changes a single protein building block (amino acid) in the bilirubin-UGT enzyme. This type of mutation, known as a missense mutation, results in reduced enzyme function.  People with Gilbert syndrome have approximately 30 percent of normal bilirubin-UGT enzyme function. As a result, unconjugated bilirubin is not glucuronidated quickly enough. This toxic substance then builds up in the body, causing mild hyperbilirubinemia.  Not everyone with the genetic changes that cause Gilbert syndrome develops hyperbilirubinemia, indicating that additional factors, such as conditions that further hinder the glucuronidation process, may be necessary for development of the condition. For example, red blood cells may break down too easily, releasing excess amounts of bilirubin that the impaired enzyme cannot keep up with. Alternatively, movement of bilirubin into the liver, where it would be glucuronidated, may be impaired. These other factors may be due to changes in other genes.
Question: What is (are) Rheumatoid Arthritis ?

Answer: Rest. People with rheumatoid arthritis need a good balance between rest and exercise; they should rest more when the disease is active and exercise more when it is not. Rest helps to reduce active joint inflammation and pain and to fight fatigue. The length of time for rest will vary from person to person, but in general, shorter rest breaks every now and then are more helpful than long times spent in bed. Exercise. Exercise is important for maintaining healthy and strong muscles, preserving joint mobility, and maintaining flexibility. Exercise can help people sleep well, reduce pain, maintain a positive attitude, and manage weight. Exercise programs should take into account the persons physical abilities, limitations, and changing needs. For more information on exercise classes, you may want to contact the Arthritis Foundation at 1-800-283-7800. Learn more about the health benefits of exercise for older adults.  More information about exercise and physical activity for older adults can be found at Go4Life, the exercise and and physical activity campaign from the National Institute on Aging. Diet. Special diets, vitamin supplements, and other alternative approaches have been suggested for treating rheumatoid arthritis. Although such approaches may not be harmful, scientific studies have not yet shown any benefits. An overall nutritious diet with the right amount of calories, protein, and calcium is important. Some people need to be careful about drinking alcoholic beverages because of the medications they take for rheumatoid arthritis. See Eating Well as You Get Older  to learn more about healthy eating.  Joint Care. Some people find that using a splint for a short time around a painful joint reduces pain and swelling by supporting the joint and letting it rest. Assistive devices may help reduce stress and lessen pain in the joints. Examples include zipper pullers and aids to help with moving in and out of chairs and beds.  Stress Reduction. Finding ways to reduce stress is important. Regular rest periods can help and so can relaxation, distraction, or visualization exercises. Exercise programs, participation in support groups, and good communication with the health care team are other ways to reduce stress.  Learn about relaxation techniques that may relieve tension.
Question: What is (are) Heart Attack ?

Answer: Blood Flow to the Heart Is Blocked The heart works 24 hours a day, pumping oxygen and nutrient-rich blood to the body. Blood is supplied to the heart through its coronary arteries. If a blood clot suddenly blocks a coronary artery, it cuts off most or all blood supply to the heart, and a heart attack results. If blood flow isn't restored quickly, the section of heart muscle begins to die. The more time that passes without treatment to restore blood flow, the greater the damage to the heart. Affects Both Men and Women Heart attacks are a leading killer of both men and women in the United States. Each year, more than one million people in the U.S. have a heart attack and about half of them die. Half of those who die do so within one hour of the start of symptoms and before reaching the hospital. The good news is that excellent treatments are available for heart attacks. These treatments can save lives and prevent disabilities. Prompt Treatment Is Important Heart attack treatment works best when it's given right after symptoms occur. Prompt treatment of a heart attack can help prevent or limit damage to the heart and prevent sudden death. Call 9-1-1 Right Away A heart attack is an emergency. Call 9-1-1 for an ambulance right away -- within 5 minutes -- if you think you or someone else may be having a heart attack. You also should call for help if your chest pain doesn't go away as it usually does when you take medicine prescribed for angina (chest pain). Do not drive to the hospital or let someone else drive you. Emergency personnel in the ambulance can begin life-saving treatment on the way to the emergency room. They carry drugs and equipment that can help your medical condition, including - oxygen   - aspirin to prevent further blood clotting   - heart medications, such as nitroglycerin   - pain relief treatments  - defibrillators that can restart the heart if it stops beating.  oxygen aspirin to prevent further blood clotting heart medications, such as nitroglycerin pain relief treatments defibrillators that can restart the heart if it stops beating. If blood flow in the blocked artery can be restored quickly, permanent heart damage may be prevented. Yet, many people do not seek medical care for 2 hours or more after symptoms start.
Question: How to diagnose Rectal Cancer ?

Answer: Tests that examine the rectum and colon are used to detect (find) and diagnose rectal cancer. Tests used to diagnose rectal cancer include the following:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.    -   Digital rectal exam (DRE): An exam of the rectum. The doctor or nurse inserts a lubricated, gloved finger into the lower part of the rectum to feel for lumps or anything else that seems unusual. In women, the vagina may also be examined.    -   Colonoscopy : A procedure to look inside the rectum and colon for polyps (small pieces of bulging tissue), abnormal areas, or cancer. A colonoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove polyps or tissue samples, which are checked under a microscope for signs of cancer.    -   Biopsy : The removal of cells or tissues so they can be viewed under a microscope to check for signs of cancer. Tumor tissue that is removed during the biopsy may be checked to see if the patient is likely to have the gene mutation that causes HNPCC. This may help to plan treatment. The following tests may be used:               -  Reverse transcriptionpolymerase chain reaction (RTPCR) test: A laboratory test in which cells in a sample of tissue are studied using chemicals to look for certain changes in the structure or function of genes.      -  Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer.             -   Carcinoembryonic antigen (CEA) assay : A test that measures the level of CEA in the blood. CEA is released into the bloodstream from both cancer cells and normal cells. When found in higher than normal amounts, it can be a sign of rectal cancer or other conditions.

Question: What is (are) Langerhans Cell Histiocytosis ?

Answer: Key Points
                    - Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body.    - Family history or having a parent who was exposed to certain chemicals may increase the risk of LCH.    - The signs and symptoms of LCH depend on where it is in the body.         - Skin and nails     - Mouth     - Bone     - Lymph nodes and thymus     - Endocrine system      - Central nervous system (CNS)     - Liver and spleen     - Lung     - Bone marrow        - Tests that examine the organs and body systems where LCH may occur are used to detect (find) and diagnose LCH.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body.
                    Langerhans cell histiocytosis (LCH) is a rare cancer that begins in LCH cells (a type of dendritic cell which fights infection). Sometimes there are mutations (changes) in LCH cells as they form. These include mutations of the  BRAF  gene. These changes may make the LCH cells grow and multiply quickly. This causes LCH cells to build up in certain parts of the body, where they can damage tissue or form lesions.    LCH is not a disease of the Langerhans cells that normally occur in the skin.   LCH may occur at any age, but is most common in young children. Treatment of LCH in children is different from treatment of LCH in adults. The treatments for LCH in children and adults are described in separate sections of this summary.   Check the list of NCI-supported cancer clinical trials that are now accepting patients with childhood Langerhans cell histiocytosis. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your child's doctor about clinical trials that may be right for your child. General information about clinical trials is available from the NCI website.
