Question:  what research (or clinical trials) is being done for Sydenham Chorea ?
Answer: The National Institute of Neurological Disorders and Stroke (NINDS) and other institutes of the National Institutes of Health (NIH) conduct research related to SD in laboratories at the NIH, and support additional research through grants to major medical institutions across the country. Currently, researchers are studying how the interplay of genetic, developmental, and environmental factors could determine a childs vulnerability to SD after a GABHS infection. Other researchers are exploring whether children whose symptoms either begin or get worse following a GABHS infection share a common set of abnormal biomolecular pathways responsible for their similar clinical symptoms.
Question:  What is (are) Fahr's Syndrome ?
Answer: Fahr's Syndrome is a rare, genetically dominant, inherited neurological disorder characterized by abnormal deposits of calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex. Symptoms of the disorder may include deterioration of motor function, dementia, seizures, headache, dysarthria (poorly articulated speech), spasticity (stiffness of the limbs) and spastic paralysis, eye impairments, and athetosis (involuntary, writhing movements). Fahr's Syndrome can also include symptoms characteristic of Parkinson's disease such as tremors, muscle rigidity, a mask-like facial appearance, shuffling gait, and a "pill-rolling" motion of the fingers. These symptoms generally occur later in the development of the disease. More common symptoms include dystonia (disordered muscle tone) and chorea (involuntary, rapid, jerky movements). Age of onset is typically in the 40s or 50s, although it can occur at any time in childhood or adolescence.
Question:  What are the treatments for Fahr's Syndrome ?
Answer: There is no cure for Fahr's Syndrome, nor is there a standard course of treatment. Treatment addresses symptoms on an individual basis.
Question:  What is the outlook for Fahr's Syndrome ?
Answer: The prognosis for any individual with Fahr's Syndrome is variable and hard to predict. There is no reliable correlation between age, extent of calcium deposits in the brain, and neurological deficit. Since the appearance of calcification is age-dependent, a CT scan could be negative in a gene carrier who is younger than the age of 55.
Question:  what research (or clinical trials) is being done for Fahr's Syndrome ?
Answer: The NINDS supports and conducts research on neurogenetic disorders such as Fahr's Syndrome. The goals of this research are to locate and understand the actions of the genes involved in this disorder. Finding these genes could lead to effective ways to treat and prevent Fahr's Syndrome.
Question:  What is (are) Lactose Intolerance ?
Answer: Lactose is a sugar found in milk and milk products. The small intestinethe organ where most food digestion and nutrient absorption take placeproduces an enzyme called lactase. Lactase breaks down lactose into two simpler forms of sugar: glucose and galactose. The body then absorbs these simpler sugars into the bloodstream.
Question:  What is (are) Lactose Intolerance ?
Answer: Lactose intolerance is a condition in which people have digestive symptomssuch as bloating, diarrhea, and gasafter eating or drinking milk or milk products.
                
Lactase deficiency and lactose malabsorption may lead to lactose intolerance:
                
- Lactase deficiency. In people who have a lactase deficiency, the small intestine produces low levels of lactase and cannot digest much lactose.  - Lactose malabsorption. Lactase deficiency may cause lactose malabsorption. In lactose malabsorption, undigested lactose passes to the colon. The colon, part of the large intestine, absorbs water from stool and changes it from a liquid to a solid form. In the colon, bacteria break down undigested lactose and create fluid and gas. Not all people with lactase deficiency and lactose malabsorption have digestive symptoms.
                
People have lactose intolerance when lactase deficiency and lactose malabsorption cause digestive symptoms. Most people with lactose intolerance can eat or drink some amount of lactose without having digestive symptoms. Individuals vary in the amount of lactose they can tolerate.
                
People sometimes confuse lactose intolerance with a milk allergy. While lactose intolerance is a digestive system disorder, a milk allergy is a reaction by the bodys immune system to one or more milk proteins. An allergic reaction to milk can be life threatening even if the person eats or drinks only a small amount of milk or milk product. A milk allergy most commonly occurs in the first year of life, while lactose intolerance occurs more often during adolescence or adulthood.1,2
                

                
Four Types of Lactase Deficiency   Four types of lactase deficiency may lead to lactose intolerance:   - Primary lactase deficiency, also called lactase nonpersistence, is the most common type of lactase deficiency. In people with this condition, lactase production declines over time. This decline often begins at about age 2; however, the decline may begin later. Children who have lactase deficiency may not experience symptoms of lactose intolerance until late adolescence or adulthood. Researchers have discovered that some people inherit genes from their parents that may cause a primary lactase deficiency.   - Secondary lactase deficiency results from injury to the small intestine. Infection, diseases, or other problems may injure the small intestine. Treating the underlying cause usually improves the lactose tolerance.   - Developmental lactase deficiency may occur in infants born prematurely. This condition usually lasts for only a short time after they are born.   - Congenital lactase deficiency is an extremely rare disorder in which the small intestine produces little or no lactase enzyme from birth. Genes inherited from parents cause this disorder.

Genes inherited from parents cause this disorder.
Question:  What are the symptoms of Lactose Intolerance ?
Answer: Common symptoms of lactose intolerance include
                
- abdominal bloating, a feeling of fullness or swelling in the abdomen  - abdominal pain  - diarrhea  - gas  - nausea
                
Symptoms occur 30 minutes to 2 hours after consuming milk or milk products. Symptoms range from mild to severe based on the amount of lactose the person ate or drank and the amount a person can tolerate.
Question:  How to diagnose Lactose Intolerance ?
Answer: A health care provider makes a diagnosis of lactose intolerance based on
                
- medical, family, and diet history, including a review of symptoms  - a physical exam  - medical tests
                
Medical, family, and diet history. A health care provider will take a medical, family, and diet history to help diagnose lactose intolerance. During this discussion, the health care provider will review a patients symptoms. However, basing a diagnosis on symptoms alone may be misleading because digestive symptoms can occur for many reasons other than lactose intolerance. For example, other conditions such as irritable bowel syndrome, celiac disease, inflammatory bowel disease, or small bowel bacterial overgrowth can cause digestive symptoms.
                
Physical exam. A physical exam may help diagnose lactose intolerance or rule out other conditions that cause digestive symptoms. During a physical exam, a health care provider usually
                
- checks for abdominal bloating  - uses a stethoscope to listen to sounds within the abdomen  - taps on the abdomen to check for tenderness or pain
                
A health care provider may recommend eliminating all milk and milk products from a persons diet for a short time to see if the symptoms resolve. Symptoms that go away when a person eliminates lactose from his or her diet may confirm the diagnosis of lactose intolerance.
                
Medical tests. A health care provider may order special tests to provide more information. Health care providers commonly use two tests to measure how well a person digests lactose:
                
- Hydrogen breath test. This test measures the amount of hydrogen in a persons breath. Normally, only a small amount of hydrogen is detectable in the breath when a person eats or drinks and digests lactose. However, undigested lactose produces high levels of hydrogen. For this test, the patient drinks a beverage that contains a known amount of lactose. A health care provider asks the patient to breathe into a balloon-type container that measures breath hydrogen level. In most cases, a health care provider performs this test at a hospital, on an outpatient basis. Smoking and some foods and medications may affect the accuracy of the results. A health care provider will tell the patient what foods or medications to avoid before the test.  - Stool acidity test. Undigested lactose creates lactic acid and other fatty acids that a stool acidity test can detect in a stool sample. Health care providers sometimes use this test to check acidity in the stools of infants and young children. A child may also have glucose in his or her stool as a result of undigested lactose. The health care provider will give the childs parent or caretaker a container for collecting the stool specimen. The parent or caretaker returns the sample to the health care provider, who sends it to a lab for analysis.
Question:  What are the treatments for Lactose Intolerance ?
Answer: Many people can manage the symptoms of lactose intolerance by changing their diet. Some people may only need to limit the amount of lactose they eat or drink. Others may need to avoid lactose altogether. Using lactase products can help some people manage their symptoms.
                
For people with secondary lactase deficiency, treating the underlying cause improves lactose tolerance. In infants with developmental lactase deficiency, the ability to digest lactose improves as the infants mature. People with primary and congenital lactase deficiency cannot change their bodys ability to produce lactase.
Question:  What to do for Lactose Intolerance ?
Answer: People may find it helpful to talk with a health care provider or a registered dietitian about a dietary plan. A dietary plan can help people manage the symptoms of lactose intolerance and make sure they get enough nutrients. Parents, caretakers, childcare providers, and others who serve food to children with lactose intolerance should follow the dietary plan recommended by the childs health care provider or registered dietitian.
                
Milk and milk products. Gradually introducing small amounts of milk or milk products may help some people adapt to them with fewer symptoms. Often, people can better tolerate milk or milk products by having them with meals, such as having milk with cereal or having cheese with crackers. People with lactose intolerance are generally more likely to tolerate hard cheeses, such as cheddar or Swiss, than a glass of milk. A 1.5ounce serving of low-fat hard cheese has less than 1 gram of lactose, while a 1-cup serving of low-fat milk has about 11 to 13 grams of lactose.2
                
However, people with lactose intolerance are also more likely to tolerate yogurt than milk, even though yogurt and milk have similar amounts of lactose.2
                
Lactose-free and lactose-reduced milk and milk products. Lactose-free and lactose-reduced milk and milk products are available at most supermarkets and are identical nutritionally to regular milk and milk products. Manufacturers treat lactose-free milk with the lactase enzyme. This enzyme breaks down the lactose in the milk. Lactose-free milk remains fresh for about the same length of time or, if it is ultra-pasteurized, longer than regular milk. Lactose-free milk may have a slightly sweeter taste than regular milk.
                
Lactase products. People can use lactase tablets and drops when they eat or drink milk products. The lactase enzyme digests the lactose in the food and therefore reduces the chances of developing digestive symptoms. People should check with a health care provider before using these products because some groups, such as young children and pregnant and breastfeeding women, may not be able to use them.

Answer: - Lactose is a sugar found in milk and milk products.  - Lactose intolerance is a condition in which people have digestive symptomssuch as bloating, diarrhea, and gasafter eating or drinking milk or milk products.  - A health care provider makes a diagnosis of lactose intolerance based on medical, family, and diet history, including a review of symptoms; a physical exam; and medical tests.  - Basing a diagnosis on symptoms alone may be misleading because digestive symptoms can occur for many reasons other than lactose intolerance.  - Most people with lactose intolerance can tolerate some amount of lactose in their diet and do not need to avoid milk or milk products completely. However, individuals vary in the amount of lactose they can tolerate.  - Research suggests that adults and adolescents with lactose malabsorption could eat or drink at least 12 grams of lactose in one sitting without symptoms or with only minor symptoms. This amount is the amount of lactose in 1 cup of milk.  - Many people can manage the symptoms of lactose intolerance by changing their diet. Some people may only need to limit the amount of lactose they eat or drink. Others may need to avoid lactose altogether.  - People may find it helpful to talk with a health care provider or a registered dietitian to determine if their diet provides adequate nutrients including calcium and vitamin D. To help ensure coordinated and safe care, people should discuss their use of complementary and alternative medical practices, including their use of dietary supplements, with their health care provider.  - Lactose is in all milk and milk products. Manufacturers also often add milk and milk products to boxed, canned, frozen, packaged, and prepared foods. People can check the ingredients on food labels to find possible sources of lactose in food products.
Question:  What is (are) What I need to know about Crohn's Disease ?
Answer: 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.
Question:  Who is at risk for What I need to know about Crohn's Disease? ?
Answer: Both men and women can get Crohn's disease, and it can run in families. People with Crohns disease may have a blood relative with the disease or another type of IBD. Crohns disease most commonly starts between the ages of 13 and 30.
Question:  What causes What I need to know about Crohn's Disease ?
Answer: Researchers are studying the possible causes of Crohns disease. Your bodys natural defense system, called the immune system, protects you from infection by fighting against bacteria, viruses, and other things that can make you sick. Researchers believe that with Crohns disease, the immune system attacks harmless bacteria and viruses. During the attack, white blood cells gather in the intestinal lining. The white blood cells cause chronic inflammation, which leads to ulcers, or sores, and damage to the intestines.
                
Other factors associated with Crohns disease are
                
- genesthe traits passed down from your parents  - unknown triggers caused by the environment
Question:  What are the symptoms of What I need to know about Crohn's Disease ?
Answer: Crohn's disease symptoms can be different for each person. The most common symptoms of Crohns disease are
                
- abdominal painoften in the lower right area of the abdomen  - diarrhea  - bleeding in the rectum, which can be seen in a persons underwear, in the toilet, or in a bowel movement; rectal bleeding can be serious and may not stop without medical help  - weight loss  - fever
Question:  What is (are) What I need to know about Crohn's Disease ?
Answer: Intestinal blockage can occur in people with Crohns disease when scar tissue blocks the intestinal passage. A narrow intestinal passage is called a stricture. When the passage blocks completely, food and stool stop moving, causing abdominal cramps and vomiting. If you have these symptoms, you should see a health care provider right away.
                
Ulcers from Crohns disease can cause tunnels to form through the inflamed areas, or even the healthy parts, of the intestine. These tunnels are called fistulas. Fistulas are seen most often in the areas around the rectum and anus. Sometimes a pocket of infection, called an abscess, can form in and around the fistulas. Most fistulas can be treated with medicines, but sometimes surgery is needed.
                
People with Crohns disease often have anemia, which can be caused by the disease itself or by iron deficiency. Anemia may make a person feel tired.
                
People with Crohns disease, particularly if they have been treated with steroid medicines, may have weakness of their bonescalled osteoporosis or osteomalacia.
                
People with Crohns disease may also have arthritis, skin problems, swelling in the eyes or mouth, kidney stones, gallstones, and liver problems. Some people with Crohns disease may have restless legs syndromeextreme leg discomfort the person feels while sitting or lying down. These problems may go away during treatment, but some must be treated with medicines.
                
People who have Crohns disease may not get enough nutrition, such as protein, vitamins, or calories, because they
                
- have an upset stomach that keeps them from eating enough calories  - may not be able to absorb nutrients in the intestine
                
Children with Crohns disease may fail to grow normally and may have low height for their age.
Question:  What to do for What I need to know about Crohn's Disease ?
Answer: Your health care provider may start you on a special diet, so you get extra nutrition and calories. High-calorie liquid supplements are often used to give you the extra calories and right amount of vitamins and minerals to keep you healthy. During acute phases of the disease, you may need to receive intravenous nutrition to give the intestine a rest.
                
No foods are known to cause injury or inflammation to the intestine. But foods such as hot spices, alcohol, greasy foods, and milk products may make diarrhea and cramping worse. You should eat a healthy diet and avoid foods that make symptoms worse. Your health care provider may refer you to a dietitian to help you with meal planning.

You should talk with your health care provider before getting pregnant.
Question:  What is (are) Smoking and the Digestive System ?
Answer: The digestive system is made up of the gastrointestinal (GI) tractalso called the digestive tractand the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestinewhich includes the colon and rectumand anus. Food enters the mouth and passes to the anus through the hollow organs of the GI tract. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The digestive system helps the body digest food, which includes breaking food down into nutrients the body needs. Nutrients are substances the body uses for energy, growth, and cell repair.
Question:  Who is at risk for Smoking and the Digestive System? ?

Question:  What is (are) Smoking and the Digestive System ?
Answer: Smoking contributes to many common disorders of the digestive system, such as heartburn and gastroesophageal reflux disease (GERD), peptic ulcers, and some liver diseases. Smoking increases the risk of Crohns disease, colon polyps, and pancreatitis, and it may increase the risk of gallstones.
Question:  What to do for Smoking and the Digestive System ?
Answer: Eating, diet, and nutrition can play a role in causing, preventing, and treating some of the diseases and disorders of the digestive system that are affected by smoking, including heartburn and GERD, liver diseases, Crohns disease, colon polyps, pancreatitis, and gallstones. More information about eating, diet, and nutrition and these conditions can be found on the Digestive Diseases A-Z list.
