[User] What causes Gum (Periodontal) Disease ?

[Assistant] If your hands have become stiff because of arthritis or if you have a physical disability, you may find it difficult to use your toothbrush or dental floss. The following tips might make it easier for you to clean your teeth and gums. Make the toothbrush easier to hold. The same kind of Velcro strap used to hold food utensils is helpful for some people. Make the toothbrush handle bigger. You can cut a small slit in the side of a tennis ball and slide it onto the handle of the toothbrush. You can also buy a toothbrush with a large handle, or you can slide a bicycle grip onto the handle. Attaching foam tubing, available from home health care catalogs, is also helpful. Try other toothbrush options. A power toothbrush might make brushing easier. Some people may find that it takes time to get used to a power toothbrush. A floss holder can make it easier to hold the dental floss. Also, talk with your dentist about whether an oral irrigation system, special small brushes, or other instruments that clean between teeth are right for you. Be sure to check with your dentist, though, before using any of these methods since they may injure the gums if used improperly.

[User] Is aniridia inherited ?

[Assistant] Aniridia is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.  In approximately two-thirds of cases, an affected person inherits the mutation from one affected parent. The remaining one-third of cases result from new mutations in the gene and occur in people with no history of the disorder in their family.

[User] What is (are) Charcot-Marie-Tooth disease type 1E ?

[Assistant] Charcot-Marie-Tooth disease type 1E (CMT1E) is a form of Charcot-Marie-Tooth disease, which is a group of rare conditions that affect the peripheral nerves. Signs and symptoms of CMT1E generally become apparent between age 5 and 25 years, although the age of onset and disease severity can vary significantly from person to person. In general, CMT1E is associated with the typical features of Charcot-Marie-Tooth disease type 1 (progressive weakness of the feet and/or ankles; foot drop; atrophy of muscles below the knee; absent tendon reflexes of upper and lower extremities; and a decreased sensitivity to touch, heat, and cold in the feet and/or lower legs) in addition to hearing loss. CMT1E is caused by certain changes (mutations) in the PMP22 gene and is inherited in an autosomal dominant manner. Treatment is based on the signs and symptoms present in each person.

[User] Is essential tremor inherited ?

[Assistant] Essential tremor can be passed through generations in families, but the inheritance pattern varies. In most affected families, essential tremor appears to be inherited in an autosomal dominant pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder, although no genes that cause essential tremor have been identified. In other families, the inheritance pattern is unclear. Essential tremor may also appear in people with no history of the disorder in their family.  In some families, some individuals have essential tremor while others have other movement disorders, such as involuntary muscle tensing (dystonia). The potential genetic connection between essential tremor and other movement disorders is an active area of research.

[User] Who is at risk for High Blood Pressure? ?

[Assistant] Not a Normal Part of Aging Nearly 1 in 3 American adults have high blood pressure. Many people get high blood pressure as they get older. However, getting high blood pressure is not a normal part of aging. There are things you can do to help keep your blood pressure normal, such as eating a healthy diet and getting more exercise. Risk Factors Anyone can develop high blood pressure. However, these factors can increase your risk for developing high blood pressure. -  age  - race or ethnicity  - being overweight  - gender  - lifestyle habits  - a family history of high blood pressure.  age race or ethnicity being overweight gender lifestyle habits a family history of high blood pressure. Age Blood pressure tends to rise with age. In fact, about 65 percent of Americans age 60 or older have high blood pressure. Race/Ethnicity High blood pressure is more common in African American adults than in Caucasian or Hispanic American adults. Compared with these ethnic groups, African Americans -  tend to get high blood pressure earlier in life  - often have higher blood pressure numbers  - are less likely to achieve target blood pressure goals with treatment. tend to get high blood pressure earlier in life often have higher blood pressure numbers are less likely to achieve target blood pressure goals with treatment. Overweight You are more likely to develop prehypertension or high blood pressure if youre overweight or obese. The terms overweight and obese refer to body weight thats greater than what is considered healthy for a certain height. Gender Before age 55, men are more likely than women to develop high blood pressure. After age 55, women are more likely than men to develop high blood pressure. Lifestyle Habits Unhealthy lifestyle habits can raise your risk for high blood pressure, and they include -  eating too much sodium or too little potassium   - lack of physical activity  - drinking too much alcohol  - smoking  - stress. eating too much sodium or too little potassium lack of physical activity drinking too much alcohol smoking stress. Family History A family history of high blood pressure raises the risk of developing prehypertension or high blood pressure. Some people have a high sensitivity to sodium and salt, which may increase their risk for high blood pressure and may run in families. Genetic causes of this condition are why family history is a risk factor for this condition.

[User] What are the genetic changes related to nephronophthisis ?

[Assistant] Nephronophthisis has several genetic causes, which are used to split the condition into distinct types. Nephronophthisis type 1, which is the most common type of the disorder and one cause of juvenile nephronophthisis, results from changes affecting the NPHP1 gene. The proteins produced from NPHP1 and the other genes involved in nephronophthisis are known or suspected to play roles in cell structures called cilia. Cilia are microscopic, finger-like projections that stick out from the surface of cells and are involved in chemical signaling. Cilia are important for the structure and function of many types of cells and tissues, including cells in the kidneys, liver, and brain and the light-sensitive tissue at the back of the eye (the retina).  The genetic mutations involved in nephronophthisis are thought to impair the structure or function of cilia in some way, which likely disrupts important chemical signaling pathways during development. Although researchers believe that defective cilia lead to the features of nephronophthisis, the mechanism remains unclear. It is unknown why some people with mutations in nephronophthisis-associated genes have only kidney problems, while others develop additional signs and symptoms.

[User] What are the treatments for Urinary Incontinence in Children ?

[Assistant]
Most UI fades away naturally as a child grows and develops and does not require treatment. When treatment is needed, options include bladder training and related strategies, moisture alarms, and medications.

Growth and Development

As children mature

- bladder capacity increases  - natural body alarms become activated  - an overactive bladder settles down  - production of ADH becomes normal  - response to the bodys signal that it is time to void improves

Bladder Training and Related Strategies

Bladder training consists of exercises to strengthen the bladder muscles to better control urination. Gradually lengthening the time between trips to the bathroom can also help by stretching the bladder so it can hold more urine. Additional techniques that may help control daytime UI include

- urinating on a scheduletimed voidingsuch as every 2 hours  - avoiding food or drinks with caffeine  - following suggestions for healthy urination, such as relaxing muscles and taking enough time to allow the bladder to empty completely

Waking children up to urinate can help decrease nighttime UI. Ensuring children drink enough fluids throughout the day so they do not drink a lot of fluids close to bedtime may also help. A health care provider can give guidance about how much a child needs to drink each day, as the amount depends on a childs age, physical activity, and other factors.

Moisture Alarms

At night, moisture alarms can wake children when they begin to urinate. These devices use a water-sensitive pad connected to an alarm that sounds when moisture is first detected. A small pad can clip to the pajamas, or a larger pad can be placed on the bed. For the alarm to be effective, children must awaken as soon as the alarm goes off, stop the urine stream, and go to the bathroom. Children using moisture alarms may need to have someone sleep in the same room to help wake them up.

Medications

Nighttime UI may be treated by increasing ADH levels. The hormone can be boosted by a synthetic version known as desmopressin (DDAVP), which is available in pill form, nasal spray, and nose drops. DDAVP is approved for use in children. Another medication, called imipramine (Tofranil), is also used to treat nighttime UI, though the way this medication prevents bedwetting is not known. Although both of these medications may help children achieve short-term success, relapse is common once the medication is withdrawn.

UI resulting from an overactive bladder may be treated with oxybutynin (Ditropan), a medication that helps calm the bladder muscle and control muscle spasms.

[User] What are the treatments for Anxiety Disorders ?

[Assistant] Most insurance plans, including health maintenance organizations (HMOs), will cover treatment for anxiety disorders. Check with your insurance company and find out. If you dont have insurance, the Health and Human Services division of your county government may offer mental health care at a public mental health center that charges people according to how much they are able to pay. If you are on public assistance, you may be able to get care through your state Medicaid plan.

[User] What is (are) inclusion body myopathy 2 ?

[Assistant] Inclusion body myopathy 2 is a condition that primarily affects skeletal muscles, which are muscles that the body uses for movement. This disorder causes muscle weakness that appears in late adolescence or early adulthood and worsens over time.  The first sign of inclusion body myopathy 2 is weakness of a muscle in the lower leg called the tibialis anterior. This muscle helps control up-and-down movement of the foot. Weakness in the tibialis anterior alters the way a person walks and makes it difficult to run and climb stairs. As the disorder progresses, weakness also develops in muscles of the upper legs, hips, shoulders, and hands. Unlike most forms of myopathy, inclusion body myopathy 2 usually does not affect the quadriceps, which are a group of large muscles at the front of the thigh. This condition also does not affect muscles of the eye or heart, and it does not cause neurological problems. Weakness in leg muscles makes walking increasingly difficult, and most people with inclusion body myopathy 2 require wheelchair assistance within 20 years after signs and symptoms appear.  People with the characteristic features of inclusion body myopathy 2 have been described in several different populations. When the condition was first reported in Japanese families, researchers called it distal myopathy with rimmed vacuoles (DMRV) or Nonaka myopathy. When a similar disorder was discovered in Iranian Jewish families, researchers called it rimmed vacuole myopathy or hereditary inclusion body myopathy (HIBM). It has since become clear that these conditions are variations of a single disorder caused by mutations in the same gene.

[User] What is (are) Brown syndrome ?

[Assistant] Brown syndrome is an eye disorder characterized by abnormalities in the eye's ability to move. Specifically, the ability to look up and in is affected by a problem in the superior oblique muscle/tendon. The condition may be present at birth (congenital) or it may develop following surgery or as a result of inflammation or a problem with development. Some cases are constant while other are intermittent. Treatment depends upon the cause and severity of the movement disorder. Options include close observation, nonsteroidal anti-inflammatory agents like Ibuprofen, corticosteroids, and surgery.

[User] how can botulism be treated?

[Assistant] The respiratory failure and paralysis that occur with severe botulism may require a patient to be on a breathing machine (ventilator) for weeks or months, plus intensive medical and nursing care. The paralysis slowly improves. Botulism can be treated with an antitoxin which blocks the action of toxin circulating in the blood. Antitoxin for infants is available from the California Department of Public Health, and antitoxin for older children and adults is available through CDC.If given before paralysis is complete, antitoxin can prevent worsening and shorten recovery time. Physicians may try to remove contaminated food still in the gut by inducing vomiting or by using enemas. Wounds should be treated, usually surgically, to remove the source of the toxin-producing bacteria followed by administration of appropriate antibiotics. Good supportive care in a hospital is the mainstay of therapy for all forms of botulism.

[User] Do you have information about Colonoscopy

[Assistant] Summary : Colonoscopy and sigmoidoscopy are procedures that let your doctor look inside your large intestine. They use instruments called scopes. Scopes have a tiny camera attached to a long, thin tube. The procedures let your doctor see things such as inflamed tissue, abnormal growths, and ulcers.     Colonoscopy checks your entire colon and rectum. Sigmoidoscopy checks the rectum and the lower colon only.    Your doctor may recommend one of these procedures       - To look for early signs of cancer in the colon and rectum. It may be part of a routine screening, which usually starts at age 50.    - To look for causes of unexplained changes in bowel habits    - To evaluate symptoms like abdominal pain, rectal bleeding, and weight loss       Your doctor can also remove polyps from your colon during these procedures.    You will get written bowel prep instructions to follow at home before the procedure. The bowel prep cleans out the intestine so your doctor can see everything clearly. During a colonoscopy, you get medicines to keep you relaxed. You usually do not need them for a sigmoidoscopy.    NIH: National Institute of Diabetes and Digestive and Kidney Diseases

[User] What is the outlook for Meningitis and Encephalitis ?

[Assistant] The prognosis for for people with encephalitis or meningitis varies. Some cases are mild, short and relatively benign and individuals have full recovery, although the process may be slow. Individuals who experience mild symptoms may recover in 2-4 weeks. Other cases are severe, and permanent impairment or death is possible. The acute phase of encephalitis may last for 1 to 2 weeks, with gradual or sudden resolution of fever and neurological symptoms. Individuals treated for bacterial meningitis typically show some relief within 48-72 hours. Neurological symptoms may require many months before full recovery. With early diagnosis and prompt treatment, most individuals recover from meningitis. However, in some cases, the disease progresses so rapidly that death occurs during the first 48 hours, despite early treatment.

[User] What is (are) Diabetic Heart Disease ?

[Assistant] If you have diabetes or pre-diabetes you have an increased risk for heart disease. Diabetic heart disease can be coronary heart disease (CHD), heart failure, and diabetic cardiomyopathy.      Diabetes by itself puts you at risk for heart disease. Other risk factors include        - Family history of heart disease    - Carrying extra weight around the waist    - Abnormal cholesterol levels    - High blood pressure    - Smoking        Some people who have diabetic heart disease have no signs or symptoms of heart disease. Others have some or all of the symptoms of heart disease.      Treatments include medications to treat heart damage or to lower your blood glucose (blood sugar), blood pressure, and cholesterol. If you are not already taking a low dose of aspirin every day, your doctor may suggest it. You also may need surgery or some other medical procedure. Lifestyle changes also help. These include a healthy diet, maintaining a healthy weight, being physically active, and quitting smoking.     NIH: National Institute of Diabetes and Digestive and Kidney Diseases

[User] What is (are) Pregnancy and Thyroid Disease ?

[Assistant]
The thyroid is a 2-inch-long, butterfly-shaped gland weighing less than 1 ounce. Located in the front of the neck below the larynx, or voice box, it has two lobes, one on either side of the windpipe. The thyroid is one of the glands that make up the endocrine system. The glands of the endocrine system produce, store, and release hormones into the bloodstream. The hormones then travel through the body and direct the activity of the bodys cells.

The thyroid gland makes two thyroid hormones, triiodothyronine (T3) and thyroxine (T4). T3 is the active hormone and is made from T4. Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels.

Thyroid hormone production is regulated by thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are high, the pituitary responds by decreasing TSH production.

[User] What are the treatments for Breast Cancer ?

[Assistant] Hormonal therapy keeps cancer cells from getting the hormones they need to grow. This treatment may include the use of drugs that change the way hormones work. Sometimes it includes surgery to remove the ovaries, which make female hormones. Like chemotherapy, hormonal therapy can affect cancer cells throughout the body. Often, women with early-stage breast cancer and those with metastatic breast cancer -- meaning cancer that has spread to other parts of the body -- receive hormone therapy in the form of tamoxifen. Hormone therapy with tamoxifen or estrogens can act on cells all over the body. However, it may increase the chance of developing endometrial cancer. If you take tamoxifen, you should have a pelvic examination every year to look for any signs of cancer. A woman should report any vaginal bleeding, other than menstrual bleeding, to her doctor as soon as possible.

[User] What is (are) Wagner syndrome ?

[Assistant] Wagner syndrome is a hereditary disorder that causes progressive vision loss. The eye problems that lead to vision loss typically begin in childhood, although the vision impairment might not be immediately apparent.  In people with Wagner syndrome, the light-sensitive tissue that lines the back of the eye (the retina) becomes thin and may separate from the back of the eye (retinal detachment). The blood vessels within the retina (known as the choroid) may also be abnormal. The retina and the choroid progressively break down (degenerate). Some people with Wagner syndrome have blurred vision because of ectopic fovea, an abnormality in which the part of the retina responsible for sharp central vision is out of place. Additionally, the thick, clear gel that fills the eyeball (the vitreous) becomes watery and thin. People with Wagner syndrome develop a clouding of the lens of the eye (cataract). Affected individuals may also experience nearsightedness (myopia), progressive night blindness, or a narrowing of their field of vision.  Vision impairment in people with Wagner syndrome can vary from near normal vision to complete loss of vision in both eyes.

[User] What is (are) Familial avascular necrosis of the femoral head ?

[Assistant] Avascular necrosis of the femoral head (ANFH) is a degenerative condition which causes the upper ends of the thigh bones (femurs) to break down due to an inadequate blood supply and deficient bone repair. It can lead to pain and limping and cause the legs to be of unequal length. The prevalence of ANFH is unknown but around 15,000 cases are reported each year in the United States, with most cases being associated with mechanical disruption (hip trauma or surgery), hypofibrinolysis (a reduced ability to dissolve clots), steroid use, smoking, alcohol intake, hemoglobinopathies and hyperlipidemia (an increase in the amount of fat - such as cholesterol and triglycerides - in the blood). Familial forms of ANFH appear to be very rare, with only a few families reported in the medical literature. Age of onset in these familial cases ranges from 15-48 years (as opposed to between 3rd to 5th decade of life for other forms of ANFH). Transmission in familial cases is autosomal dominant and mutations in the type II collagen gene (COL2A1) have been detected in affected family members.

[User] What is (are) Chiari Malformation ?

[Assistant] Chiari malformations (CMs) are structural defects in the cerebellum. The cerebellum is the part of the brain that controls balance. With CM, brain tissue extends into the spinal canal. It can happen when part of the skull is too small, which pushes the brain tissue down. There are several types of CM. One type often happens in children who have neural tube defects. Some types cause no symptoms and don't need treatment. If you have symptoms, they may include       - Neck pain    - Balance problems    - Numbness or other abnormal feelings in the arms or legs    - Dizziness    - Vision problems    - Difficulty swallowing    - Poor hand coordination       Doctors diagnose CM using imaging tests. Medicines may ease some symptoms, such as pain. Surgery is the only treatment available to correct or stop the progression of nerve damage.

[Assistant] How is postural orthostatic tachycardia syndrome treated? Because postural orthostatic tachycardia syndrome (POTS) is thought to have a variety of causes, there is no single treatment that is effective for all people with the condition. In general, management of POTS aims to relieve low blood volume and/or regulate circulatory problems that could be causing the condition. In some affected people, simple life style interventions such as adding extra salt to the diet, ensuring adequate fluid intake, participating in a specialized exercise program, and avoiding factors that exacerbate the condition appear to improve symptoms. Certain medications have also been used to treat POTS with some success.

[User] What are the treatments for Hemochromatosis ?

[Assistant]
Health care providers treat hemochromatosis by drawing blood. This process is called phlebotomy. Phlebotomy rids the body of extra iron. This treatment is simple, inexpensive, and safe.

Based on the severity of the iron overload, a patient will have phlebotomy to remove a pint of blood once or twice a week for several months to a year, and occasionally longer. Health care providers will test serum ferritin levels periodically to monitor iron levels. The goal is to bring serum ferritin levels to the low end of the average range and keep them there. Depending on the lab, the level is 25 to 50 g/L.

After phlebotomy reduces serum ferritin levels to the desired level, patients may need maintenance phlebotomy treatment every few months. Some patients may need phlebotomies more often. Serum ferritin tests every 6 months or once a year will help determine how often a patient should have blood drawn. Many blood donation centers provide free phlebotomy treatment for people with hemochromatosis.

Treating hemochromatosis before organs are damaged can prevent complications such as cirrhosis, heart problems, arthritis, and diabetes. Treatment cannot cure these conditions in patients who already have them at diagnosis. However, treatment will help most of these conditions improve. The treatments effectiveness depends on the degree of organ damage. For example, treating hemochromatosis can stop the progression of liver damage in its early stages and lead to a normal life expectancy. However, if a patient develops cirrhosis, his or her chance of developing liver cancer increases, even with phlebotomy treatment. Arthritis usually does not improve even after phlebotomy removes extra iron.

[User] What are the treatments for What I need to know about Hepatitis B ?

[Assistant]
Hepatitis B is not usually treated unless it becomes chronic. Chronic hepatitis B is treated with medicines that slow or stop the virus from damaging the liver.

Medicines for Chronic Hepatitis B

Your doctor will choose medicines or a combination of medicines that are likely to work for you. The doctor will closely watch your symptoms and schedule regular blood tests to make sure treatment is working.

Medicines given by shots include

- interferon  - peginterferon

Medicines taken by mouth include

- adefovir  - entecavir  - lamivudine  - telbivudine  - tenofovir

The length of treatment varies. Talk with your doctor before taking other prescription medicines and over-the-counter medicines.

Liver Transplant

A liver transplant may be necessary if chronic hepatitis B causes severe liver damage that leads to liver failure. Symptoms of severe liver damage include the symptoms of hepatitis B and

- generalized itching  - a longer than usual amount of time for bleeding to stop  - easy bruising  - swollen stomach or ankles  - spiderlike blood vessels, called spider angiomas, that develop on the skin

Liver transplant is surgery to remove a diseased or injured liver and replace it with a healthy one from another person, called a donor. If your doctors tell you that you need a transplant, you should talk with them about the long-term demands of living with a liver transplant.

A team of surgeonsdoctors who specialize in surgeryperforms a liver transplant in a hospital. You will learn how to take care of yourself after you go home and about the medicines youll need to take to protect your new liver. Medicines taken after liver transplant surgery can prevent hepatitis B from coming back.

Testing for Liver Cancer

Having hepatitis B increases your risk for getting liver cancer, so your doctor may suggest an ultrasound test of the liver every 6 to 12 months. Finding cancer early makes it more treatable. Ultrasound is a machine that uses sound waves to create a picture of your liver. Ultrasound is performed at a hospital or radiology center by a specially trained technician. The image, called a sonogram, can show the livers size and the presence of cancerous tumors.

[User] What causes National Hormone and Pituitary Program (NHPP): Information for People Treated with Pituitary Human Growth Hormone (Comprehensive Report) ?

[Assistant]
We have not found any particular preparation of pituitary hGH that is especially likely to carry CJD. We believe that CJD did not come from a single infected pituitary gland or preparation. Prior to 1977, in an effort to extract as much hormone as possible from the pituitary glands, the glands were often processed repeatedly. Hormone extracted from the same pituitaries was often included in many hormone preparations. Also, patients who got CJD were treated on average for 8.4 years and received many different hormone preparations. This makes it very difficult to identify any preparation associated with transmitting CJD.

Doctors wanted to see if a specific preparation of pituitary hGH could transmit CJD. To try to find the pituitary hGH that could have caused CJD, HHS researchers did two things:

1. They set up a test in animals, injecting samples of all available preparations of pituitary hGH directly into the brains of monkeys. CJD develops more rapidly if injected into the brain than under the skin, as hGH was used in people. The animals were watched for 10 years. The brains of all animals were examined for signs of CJD. If an animal got sick with CJD, it would help researchers to understand which vials of pituitary hGH were contaminated with the agent that causes CJD.

2. They studied people treated with pituitary hGH to see who got CJD and which hormone preparation they might have received based on which preparations were sent to their doctor.

Results:

- The animal tests did not help find the pituitary hGH that might have caused CJD. One animal developed the disease 5 years after injection of pituitary hGH. Two other animals that received injections from different vials of the same pituitary hGH preparation did not develop CJD.  - None of the people who developed CJD are known to have received the hormone preparation that made the animal sick. At most, two patients (whose records are incomplete) may have received this pituitary hGH preparation. Because of this, we do not believe that the patients who received the hormone preparation that transmitted CJD to the animal have a greater risk of developing CJD than others treated with pituitary hGH. Because each preparation of pituitary hGH was used to fill multiple vials, it is not known if CJD contamination was spread evenly among all vials of pituitary hGH that came from a particular preparation. It's possible that one vial got more contamination and another got little or none from the same preparation of pituitary hGH. It is believed that multiple preparations of pituitary hGH probably had very low levels of the CJD infectious agent. With such low levels of contamination, some vials of a preparation might carry CJD while other vials would not. Further, most of the people who got CJD received pituitary hGH for long periods of time and received many different preparations.

[User] What to do for Irritable Bowel Syndrome in Children ?

[Assistant]
Large meals can cause cramping and diarrhea, so eating smaller meals more often, or eating smaller portions, may help IBS symptoms. Eating meals that are low in fat and high in carbohydrates, such as pasta, rice, whole-grain breads and cereals, fruits, and vegetables may help.

Certain foods and drinks may cause IBS symptoms in some children, such as

- foods high in fat  - milk products  - drinks with caffeine  - drinks with large amounts of artificial sweeteners, which are substances used in place of sugar  - foods that may cause gas, such as beans and cabbage

Children with IBS may want to limit or avoid these foods. Keeping a food diary is a good way to track which foods cause symptoms so they can be excluded from or reduced in the diet.

Dietary fiber may lessen constipation in children with IBS, but it may not help with lowering pain. Fiber helps keep stool soft so it moves smoothly through the colon. The Academy of Nutrition and Dietetics recommends children consume age plus 5 grams of fiber daily. A 7-year-old child, for example, should get 7 plus 5, or 12 grams, of fiber a day.3 Fiber may cause gas and trigger symptoms in some children with IBS. Increasing fiber intake by 2 to 3 grams per day may help reduce the risk of increased gas and bloating.

Medications

The health care provider will select medications based on the childs symptoms. Caregivers should not give children any medications unless told to do so by a health care provider.

- Fiber supplements. Fiber supplements may be recommended to relieve constipation when increasing dietary fiber is ineffective.  - Laxatives. Constipation can be treated with laxative medications. Laxatives work in different ways, and a health care provider can provide information about which type is best. Caregivers should not give children laxatives unless told to do so by a health care provider. More information about different types of laxatives is provided in the NIDDK health topic, Constipation.  - Antidiarrheals. Loperamide has been found to reduce diarrhea in children with IBS, though it does not reduce pain, bloating, or other symptoms. Loperamide reduces stool frequency and improves stool consistency by slowing the movement of stool through the colon. Medications to treat diarrhea in adults can be dangerous for infants and children and should only be given if told to do so by a health care provider.  - Antispasmodics. Antispasmodics, such as hyoscine, cimetropium, and pinaverium, help to control colon muscle spasms and reduce abdominal pain.  - Antidepressants. Tricyclic antidepressants and selective serotonin reuptake inhibitors in low doses can help relieve IBS symptoms including abdominal pain. These medications are thought to reduce the perception of pain, improve mood and sleep patterns, and adjust the activity of the GI tract.

Probiotics

Probiotics are live microorganisms, usually bacteria, that are similar to microorganisms normally found in the GI tract. Studies have found that probiotics, specifically Bifidobacteria and certain probiotic combinations, improve symptoms of IBS when taken in large enough amounts. But more research is needed. Probiotics can be found in dietary supplements, such as capsules, tablets, and powders, and in some foods, such as yogurt. A health care provider can give information about the right kind and right amount of probiotics to take to improve IBS symptoms. More information about probiotics can be found in the National Center for Complementary and Alternative Medicine fact sheet An Introduction to Probiotics.

Therapies for Mental Health Problems

The following therapies can help improve IBS symptoms due to mental health problems:

- Talk therapy. Talking with a therapist may reduce stress and improve IBS symptoms. Two types of talk therapy used to treat IBS are cognitive behavioral therapy and psychodynamic, or interpersonal, therapy. Cognitive behavioral therapy focuses on the childs thoughts and actions. Psychodynamic therapy focuses on how emotions affect IBS symptoms. This type of therapy often involves relaxation and stress management techniques.  - Hypnotherapy. In hypnotherapy, the therapist uses hypnosis to help the child relax into a trancelike state. This type of therapy may help the child relax the muscles in the colon.

[User] What are the genetic changes related to cystic fibrosis ?

[Assistant] Mutations in the CFTR gene cause cystic fibrosis. The CFTR gene provides instructions for making a channel that transports negatively charged particles called chloride ions into and out of cells. Chloride is a component of sodium chloride, a common salt found in sweat. Chloride also has important functions in cells; for example, the flow of chloride ions helps control the movement of water in tissues, which is necessary for the production of thin, freely flowing mucus.  Mutations in the CFTR gene disrupt the function of the chloride channels, preventing them from regulating the flow of chloride ions and water across cell membranes. As a result, cells that line the passageways of the lungs, pancreas, and other organs produce mucus that is unusually thick and sticky. This mucus clogs the airways and various ducts, causing the characteristic signs and symptoms of cystic fibrosis.  Other genetic and environmental factors likely influence the severity of the condition. For example, mutations in genes other than CFTR might help explain why some people with cystic fibrosis are more severely affected than others. Most of these genetic changes have not been identified, however.

[User] Is Apert syndrome inherited ?

[Assistant] Apert syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Almost all cases of Apert syndrome result from new mutations in the gene, and occur in people with no history of the disorder in their family. Individuals with Apert syndrome, however, can pass along the condition to the next generation.

[User] What to do for Hemochromatosis ?

[Assistant]
Iron is an essential nutrient found in many foods. Healthy people usually absorb less than 10 percent of iron in the food they eat.6 People with hemochromatosis absorb up to 30 percent of that iron.6 People with hemochromatosis can help prevent iron overload by

- eating only moderate amounts of iron-rich foods, such as red meat and organ meat  - avoiding supplements that contain iron  - avoiding supplements that contain vitamin C, which increases iron absorption

People with hemochromatosis can take steps to help prevent liver damage, including

- limiting the amount of alcoholic beverages they drink because alcohol increases their chance of cirrhosis and liver cancer  - avoiding alcoholic beverages entirely if they already have cirrhosis

[User] What are the genetic changes related to adenylosuccinate lyase deficiency ?

[Assistant] All forms of adenylosuccinate lyase deficiency are caused by mutations in the ADSL gene. This gene provides instructions for making an enzyme called adenylosuccinate lyase, which performs two steps in the process that produces purine nucleotides. These nucleotides are building blocks of DNA, its chemical cousin RNA, and molecules such as ATP that serve as energy sources in the cell. Adenylosuccinate lyase converts a molecule called succinylaminoimidazole carboxamide ribotide (SAICAR) to aminoimidazole carboxamide ribotide (AICAR) and converts succinyladenosine monophosphate (SAMP) to adenosine monophosphate (AMP).  Most of the mutations involved in adenylosuccinate lyase deficiency change single protein building blocks (amino acids) in the adenylosuccinate lyase enzyme, which impairs its function. Reduced function of this enzyme leads to buildup of SAICAR and SAMP, which are converted through a different reaction to succinylaminoimidazole carboxamide riboside (SAICAr) and succinyladenosine (S-Ado). Researchers believe that SAICAr and S-Ado are toxic; damage to brain tissue caused by one or both of these substances likely underlies the neurological problems that occur in adenylosuccinate lyase deficiency.  Studies suggest that the amount of SAICAr relative to S-Ado reflects the severity of adenylosuccinate lyase deficiency. Individuals with more SAICAr than S-Ado have more severe encephalopathy and psychomotor delay.

[Assistant] Primary melanoma of the gastrointestinal (GI) tract refers to a melanoma starting in the stomach, intestines, salivary glands, mouth, esophagus, liver, pancreas, gallbladder, or rectum. Melanoma is a disease in which malignant (cancer) cells form in the melanocytes. Melanocytes are commonly found in the skin and are the cells that give the skin color. While it is not uncommon for melanomas to start in the skin and later spread to other parts of the body, melanomas originating in the gastrointestinal tract are rare. The most frequently reported site is in the esophagus and anorectum.

[User] What are the symptoms of Atrial Fibrillation ?

[Assistant]
Atrial fibrillation (AF) usually causes the heart's lower chambers, the ventricles, to contract faster than normal.

When this happens, the ventricles can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body. This can lead to signs and symptoms, such as:

Palpitations (feelings that your heart is skipping a beat, fluttering, or beating too hard or fast)

Shortness of breath

Weakness or problems exercising

Chest pain

Dizziness or fainting

Fatigue (tiredness)

Confusion

Atrial Fibrillation Complications

AF has two major complicationsstroke and heart failure.

Stroke

During AF, the heart's upper chambers, the atria, don't pump all of their blood to the ventricles. Some blood pools in the atria. When this happens, a blood clot (also called a thrombus) can form.

If the clot breaks off and travels to the brain, it can cause a stroke. (A clot that forms in one part of the body and travels in the bloodstream to another part of the body is called an embolus.)

Blood-thinning medicines that reduce the risk of stroke are an important part of treatment for people who have AF.

Atrial Fibrillation and Stroke

Heart Failure

Heart failure occurs if the heart can't pump enough blood to meet the body's needs. AF can lead to heart failure because the ventricles are beating very fast and can't completely fill with blood. Thus, they may not be able to pump enough blood to the lungs and body.

Fatigue and shortness of breath are common symptoms of heart failure. A buildup of fluid in the lungs causes these symptoms. Fluid also can build up in the feet, ankles, and legs, causing weight gain.

Lifestyle changes, medicines, and procedures or surgery (rarely, a mechanical heart pump or heart transplant) are the main treatments for heart failure.

Although this virus generally causes no signs or symptoms, some affected people may later develop adult T-cell leukemia (ATL), HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) or other medical conditions. HTLV-1 is spread by blood transfusions, sexual contact and sharing needles. It can also be spread from mother to child during birth or breast-feeding. There is no cure or treatment for HTLV-1 and it is considered a lifelong condition; however, most (95%) infected people remain asymptomatic (show no symptoms) throughout life.

[User] What is (are) Dermal eccrine cylindroma ?

[Assistant] Cylindromas are non-cancerous (benign) tumors that develop from the skin. They most commonly occur on the head and neck and rarely become cancerous (malignant).  An individual can develop one or many cylindromas; if a person develops only one, the cylindroma likely occurred by chance and typically is not inherited. They usually begin to form during mid-adulthood as a slow-growing, rubbery nodule that causes no symptoms. The development of multiple cylindromas can be hereditary and is inherited in an autosomal dominant manner; this condition is called familial cylindromatosis.  Individuals with the inherited form begin to develop many, rounded nodules of various size shortly after puberty. The tumors grow very slowly and increase in number over time.

[Assistant] What are the signs and symptoms of Keratosis follicularis dwarfism and cerebral atrophy? The Human Phenotype Ontology provides the following list of signs and symptoms for Keratosis follicularis dwarfism and cerebral atrophy. 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) Alopecia 90% Cerebral cortical atrophy 90% Hyperkeratosis 90% Microcephaly 90% Short stature 90% Abnormality of the eyelashes 50% Aplasia/Hypoplasia of the eyebrow 50% Absent eyebrow - Absent eyelashes - Cerebral atrophy - Death in childhood - Generalized keratosis follicularis - Severe short stature - X-linked inheritance - 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.

[User] What are the genetic changes related to neurofibromatosis type 2 ?

[Assistant] Mutations in the NF2 gene cause neurofibromatosis type 2. The NF2 gene provides instructions for making a protein called merlin (also known as schwannomin). This protein is produced in the nervous system, particularly in Schwann cells, which surround and insulate nerve cells (neurons) in the brain and spinal cord. Merlin acts as a tumor suppressor, which means that it keeps cells from growing and dividing too rapidly or in an uncontrolled way. Although its exact function is unknown, this protein is likely also involved in controlling cell movement, cell shape, and communication between cells. Mutations in the NF2 gene lead to the production of a nonfunctional version of the merlin protein that cannot regulate the growth and division of cells. Research suggests that the loss of merlin allows cells, especially Schwann cells, to multiply too frequently and form the tumors characteristic of neurofibromatosis type 2.

[User] What causes Benign schwannoma ?

[Assistant] What causes schwannomas? The cause of schwannomas is unknown. They sometimes occur in people with certain disorders including some types of neurofibromatosis (neurofibromatosis type 2 and schwannomatosis). In these cases, affected people have multiple tumors that are due to changes (mutations) in a gene. For example, neurofibromatosis type 2 is caused by mutations in the NF2 gene and schwannomatosis is caused by mutations in the SMARCB1 gene and the LZTR1 gene.

[User] What causes Peutz-Jeghers syndrome ?

[Assistant] What causes Peutz-Jeghers syndrome? Peutz-Jeghers syndrome (PJS) is caused by changes (mutations) in the STK11 gene. STK11 is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in STK11 result in a defective protein that is unable to carry out its normal role. This leads to the development of the polyps and tumors found in PJS. Some people with PJS do not have mutations in the STK11 gene. In these cases, the cause is unknown.

[User] What is (are) Ulcerative Colitis ?

[Assistant]
The large intestine is part of the GI tract, a series of hollow organs joined in a long, twisting tube from the mouth to the anusan opening through which stool leaves the body. The last part of the GI tract, called the lower GI tract, consists of the large intestinewhich includes the appendix, cecum, colon, and rectumand anus. The intestines are sometimes called the bowel.

The large intestine is about 5 feet long in adults and absorbs water and any remaining nutrients from partially digested food passed from the small intestine. The large intestine changes waste from liquid to a solid matter called stool. Stool passes from the colon to the rectum. The rectum is located between the lower, or sigmoid, colon and the anus. The rectum stores stool prior to a bowel movement, when stool moves from the rectum to the anus and out of a person's body.

[User] What is (are) Dry Eye ?

[Assistant] There are two types of dry eye: aqueous tear-deficient dry eye and evaporative dry eye. Aqueous tear-deficient dry eye is a disorder in which the tear glands do not produce enough of the watery component of tears to maintain a healthy eye surface, called the cornea. Evaporative dry eye may result from inflammation of the meibomian glands, located in the eyelids. These glands make the oily part of tears that slows evaporation and keeps the tears stable. Dry eye can be associated with - inflammation of the surface of the eye (cornea), the lacrimal gland, or the conjunctiva (the surface layer of tissue that lines the eyelids and covers the front part of the eye)  - any disease process that alters the components of the tears  - an increase in the surface of the eye, as in thyroid disease when the eye bulges forward  - cosmetic surgery, if the eyelids are opened too widely. inflammation of the surface of the eye (cornea), the lacrimal gland, or the conjunctiva (the surface layer of tissue that lines the eyelids and covers the front part of the eye) any disease process that alters the components of the tears an increase in the surface of the eye, as in thyroid disease when the eye bulges forward cosmetic surgery, if the eyelids are opened too widely.

[User] What are the stages of Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer ?

[Assistant]
Key Points
                    - After ovarian, fallopian tube, or peritoneal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the ovaries or to other parts of the body.     - There are three ways that cancer spreads in the body.    - Cancer may spread from where it began to other parts of the body.    - The following stages are used for ovarian epithelial, fallopian tube, and primary peritoneal cancer:         - Stage I     - Stage II     - Stage III     - Stage IV        - Ovarian epithelial, fallopian tube, and primary peritoneal cancers are grouped for treatment as early or advanced cancer.

                    After ovarian, fallopian tube, or peritoneal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the ovaries or to other parts of the body.
                    The process used to find out whether cancer has spread within the organ or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The results of the tests used to diagnose cancer are often also used to stage the disease. (See the General Information section.)

                    There are three ways that cancer spreads in the body.
                    Cancer can spread through tissue, the lymph system, and the blood:         - Tissue. The cancer spreads from where it began by growing into nearby areas.     - Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.     - Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.

                    Cancer may spread from where it began to other parts of the body.
                    When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.         - Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.    - Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.        The metastatic tumor is the same type of cancer as the primary tumor. For example, if ovarian epithelial cancer spreads to the lung, the cancer cells in the lung are actually ovarian epithelial cancer cells. The disease is metastatic ovarian epithelial cancer, not lung cancer.

                    The following stages are used for ovarian epithelial, fallopian tube, and primary peritoneal cancer:
                    Stage I     In stage I, cancer is found in one or both ovaries or fallopian tubes. Stage I is divided into stage IA, stage IB, and stage IC.            -  Stage IA: Cancer is found inside a single ovary or fallopian tube.     -  Stage IB: Cancer is found inside both ovaries or fallopian tubes.     -  Stage IC: Cancer is found inside one or both ovaries or fallopian tubes and one of the following is true:                   - cancer is also found on the outside surface of one or both ovaries or fallopian tubes; or       - the capsule (outer covering) of the ovary ruptured (broke open) before or during surgery; or       - cancer cells are found in the fluid of the peritoneal cavity (the body cavity that contains most of the organs in the abdomen) or in washings of the peritoneum (tissue lining the peritoneal cavity).                         Stage II     In stage II, cancer is found in one or both ovaries or fallopian tubes and has spread into other areas of the pelvis, or primary peritoneal cancer is found within the pelvis. Stage II ovarian epithelial and fallopian tube cancers are divided into stage IIA and stage IIB.            -  Stage IIA: Cancer has spread from where it first formed to the uterus and/or the fallopian tubes and/or the ovaries.     -  Stage IIB: Cancer has spread from the ovary or fallopian tube to organs in the peritoneal cavity (the space that contains the abdominal organs).               Stage III    In stage III, cancer is found in one or both ovaries or fallopian tubes, or is primary peritoneal cancer, and has spread outside the pelvis to other parts of the abdomen and/or to nearby lymph nodes. Stage III is divided into stage IIIA, stage IIIB, and stage IIIC.            - In stage IIIA, one of the following is true:                  - Cancer has spread to lymph nodes in the area outside or behind the peritoneum only; or       - Cancer cells that can be seen only with a microscope have spread to the surface of the peritoneum outside the pelvis. Cancer may have spread to nearby lymph nodes.                 -  Stage IIIB: Cancer has spread to the peritoneum outside the pelvis and the cancer in the peritoneum is 2 centimeters or smaller. Cancer may have spread to lymph nodes behind the peritoneum.     -  Stage IIIC: Cancer has spread to the peritoneum outside the pelvis and the cancer in the peritoneum is larger than 2 centimeters. Cancer may have spread to lymph nodes behind the peritoneum or to the surface of the liver or spleen.              Stage IV     In stage IV, cancer has spread beyond the abdomen to other parts of the body. Stage IV is divided into stage IVA and stage IVB.            -  Stage IVA: Cancer cells are found in extra fluid that builds up around the lungs.     -  Stage IVB: Cancer has spread to organs and tissues outside the abdomen, including lymph nodes in the groin.

                    Ovarian epithelial, fallopian tube, and primary peritoneal cancers are grouped for treatment as early or advanced cancer.
                    Stage I ovarian epithelial and fallopian tube cancers are treated as early cancers.   Stages II, III, and IV ovarian epithelial, fallopian tube, and primary peritoneal cancers are treated as advanced cancers.

[User] What is (are) Pulmonary Hypertension ?

[Assistant] Pulmonary hypertension (PH) is high blood pressure in the arteries to your lungs. It is a serious condition. If you have it, the blood vessels that carry blood from your heart to your lungs become hard and narrow. Your heart has to work harder to pump the blood through. Over time, your heart weakens and cannot do its job and you can develop heart failure.     Symptoms of PH include       - Shortness of breath during routine activity, such as climbing two flights of stairs    - Tiredness    - Chest pain    - A racing heartbeat    - Pain on the upper right side of the abdomen    - Decreased appetite       As PH worsens, you may find it hard to do any physical activities.    There are two main kinds of PH. One runs in families or appears for no known reason. The other kind is related to another condition, usually heart or lung disease.     There is no cure for PH. Treatments can control symptoms. They involve treating the heart or lung disease, medicines, oxygen, and sometimes lung transplantation.    NIH: National Heart, Lung, and Blood Institute
