Question: Do you have information about Vitamins

Answer: Summary : Vitamins are substances that your body needs to grow and develop normally. There are 13 vitamins your body needs. They are       - Vitamin A    - B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate)    - Vitamin C    - Vitamin D    - Vitamin E    - Vitamin K       You can usually get all your vitamins from the foods you eat. Your body can also make vitamins D and K. People who eat a vegetarian diet may need to take a vitamin B12 supplement.     Each vitamin has specific jobs. If you have low levels of certain vitamins, you may get health problems. For example, if you don't get enough vitamin C, you could become anemic. Some vitamins may help prevent medical problems. Vitamin A prevents night blindness.    The best way to get enough vitamins is to eat a balanced diet with a variety of foods. In some cases, you may need to take vitamin supplements. It's a good idea to ask your health care provider first. High doses of some vitamins can cause problems.
Question: What is (are) Moyamoya disease ?

Answer: Moyamoya disease is a rare, progressive, blood vessel disease caused by blocked arteries at the base of the brain in an area called the basal ganglia. The name "moyamoya" means "puff of smoke" in Japanese and describes the look of the tangled vessels that form to compensate for the blockage. This condition usually affects children, but can affect adults. Affected people are at increased risk for blood clots, strokes, and transient ischemic attacks (TIAs) which are frequently accompanied by seizures and muscular weakness, or paralysis on one side of the body. Affected people may also have disturbed consciousness, speech deficits (usually aphasia), sensory and cognitive impairments, involuntary movements, and vision problems. Researchers believe that Moyamoya disease is an inherited condition because it tends to run in families. Moyamoya syndrome is a related term that refers to cases of moyamoya disease that occur in association with other conditions or risk factors, such as neurofibromatosis, tuberculosis meningitis, sickle cell disease, leptospirosis, brain tumors, Sturge-Weber syndrome, and tuberous sclerosis.
Question: What is (are) Rh deficiency syndrome ?

Answer: The Rh deficiency syndrome, also known as Rh-null syndrome, is a blood disorder where people have red blood cells (RBCs) lacking all Rh antigens. The Rh antigens maintain the integrity of the RBC membrane and therefore, RBCs which lack Rh antigens have an abnormal shape. There are two types of Rh deficiency syndrome: The regulator type is associated with many different changes (mutations) in the RHAG gene .  The amorph type is caused by inactive copies of a gene (silent alleles) at the RH locus. As a result, the RBCs do not express any of the Rh antigens. The absence of the Rh complex alters the RBC shape, increases its tendency to break down (osmotic fragility), and shortens its lifespan, resulting in a hemolytic anemia that is usually mild. These patients are at risk of having adverse transfusion reactions because they may produce antibodies against several of the Rh antigens and can only receive blood from people who have the same condition. Rh deficiency syndrome is inherited in an autosomal recessive manner. Management is individualized according to the severity of hemolytic anemia.
Question: How to diagnose Severe combined immunodeficiency ?

Answer: How is severe combined immunodeficiency (SCID) diagnosed? A diagnosis of severe combined immunodeficiency (SCID) may be suspected if a baby shows any of the following persistent symptoms within the first year of life: Eight or more ear infections Two or more cases of pneumonia Infections that do not resolve with antibiotic treatment for two or more months Failure to gain weight or grow normally Infections that require intravenous antibiotic treatment Deep-seated infections, such as pneumonia that affects an entire lung or an abscess in the liver Persistent thrush in the mouth or throat A family history of immune deficiency or infant deaths due to infections Diagnosis can be confirmed by blood tests. Blood tests show significantly lower-than-normal levels of T cells and antibodies.

Question: What are the treatments for Familial atrial fibrillation ?

Answer: How might familial atrial fibrillation be treated? We are unaware of treatment recommendations specific to familial atrial fibrillation, but there is information available about treatment for atrial fibrillation in general. Treatment for atrial fibrillation depends on the frequency and severity of symptoms and may involve medications, medical procedures, and lifestyle changes. People who don't have symptoms or related heart problems may not need treatment. The main goals of treatment include: Preventing blot clots and lowering risk of stroke. This may involve blood-thinning medications such as warfarin, dabigatran, heparin, and aspirin. Controlling the rate of contractions of the ventricles (rate control). This may involve medications to restore the heart rate to a normal level, such as beta blockers, calcium channel blockers, and digitalis. Restoring a normal heart rhythm (rhythm control). This is typically for people who don't do well with rate control treatment, or for people who recently began having symptoms. Rhythm control may involve medications or procedures and is usually begun in a hospital for monitoring. Procedures may include cardioversion, catheter ablation, or maze surgery.
Question: What is (are) Spasticity ?

Answer: Spasticity is a condition in which there is an abnormal increase in muscle tone or stiffness of muscle, which might interfere with movement, speech, or be associated with discomfort or pain. Spasticity is usually caused by damage to nerve pathways within the brain or spinal cord that control muscle movement. It may occur in association with spinal cord injury, multiple sclerosis, cerebral palsy, stroke, brain or head trauma, amyotrophic lateral sclerosis, hereditary spastic paraplegias, and metabolic diseases such as adrenoleukodystrophy, phenylketonuria, and Krabbe disease. Symptoms may include hypertonicity (increased muscle tone), clonus (a series of rapid muscle contractions), exaggerated deep tendon reflexes, muscle spasms, scissoring (involuntary crossing of the legs), and fixed joints (contractures). The degree of spasticity varies from mild muscle stiffness to severe, painful, and uncontrollable muscle spasms. Spasticity can interfere with rehabilitation in patients with certain disorders, and often interferes with daily activities.
Question: what research (or clinical trials) is being done for Traumatic Brain Injury ?

Answer: The National Institute of Neurological Disorders and Stroke (NINDS) supports TBI research through grants to major medical institutions across the country and conducts TBI research in its intramural laboratories and Clinical Center at the National Institutes of Health (NIH) in Bethesda,Maryland. The Center for Neuroscience and Regenerative Medicine (CNRM) is a TBI research collaboration between intramural NIH and the Uniformed Services University for the Health Sciences (USUHS). NINDS-funded research involves studies in the laboratory and in clinical settings to better understand TBI and the biological mechanisms underlying damage to the brain. This research will allow scientists to develop strategies and interventions to limit the primary and secondary brain damage that occurs within days of a head trauma, and to devise therapies to treat brain injury and improve long-term recovery of function.

Question: What is (are) Epilepsy ?

Answer: The epilepsies are a spectrum of brain disorders ranging from severe, life-threatening and disabling, to ones that are much more benign. In epilepsy, the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes convulsions, muscle spasms, and loss of consciousness. The epilepsies have many possible causes and there are several types of seizures. Anything that disturbs the normal pattern of neuron activityfrom illness to brain damage to abnormal brain developmentcan lead to seizures. Epilepsy may develop because of an abnormality in brain wiring, an imbalance of nerve signaling chemicals called neurotransmitters, changes in important features of brain cells called channels, or some combination of these and other factors. Having a single seizure as the result of a high fever (called febrile seizure) or head injury does not necessarily mean that a person has epilepsy. Only when a person has had two or more seizures is he or she considered to have epilepsy. A measurement of electrical activity in the brain and brain scans such as magnetic resonance imaging or computed tomography are common diagnostic tests for epilepsy.
Question: What are the genetic changes related to congenital fiber-type disproportion ?

Answer: Mutations in multiple genes can cause congenital fiber-type disproportion. Mutations in the TPM3, RYR1 and ACTA1 genes cause 35 to 50 percent of cases, while mutations in other genes, some known and some unidentified, are responsible for the remaining cases.  The genes that cause congenital fiber-type disproportion provide instructions for making proteins that are involved in the tensing of muscle fibers (muscle contraction). Changes in these proteins lead to impaired muscle contraction, resulting in muscle weakness.  Skeletal muscle is made up of two types of muscle fibers: type I (slow twitch fibers) and type II (fast twitch fibers). Normally, type I and type II fibers are the same size. In people with congenital fiber-type disproportion, type I skeletal muscle fibers are significantly smaller than type II skeletal muscle fibers. It is unclear whether the small type I skeletal muscle fibers lead to muscle weakness or are caused by muscle weakness in people with congenital fiber-type disproportion.
Question: What is (are) Frasier syndrome ?

Answer: Frasier syndrome is a condition that affects the kidneys and genitalia.  Frasier syndrome is characterized by kidney disease that begins in early childhood. Affected individuals have a condition called focal segmental glomerulosclerosis, in which scar tissue forms in some glomeruli, which are the tiny blood vessels in the kidneys that filter waste from blood. In people with Frasier syndrome, this condition often leads to kidney failure by adolescence.  Although males with Frasier syndrome have the typical male chromosome pattern (46,XY), they have gonadal dysgenesis, in which external genitalia do not look clearly male or clearly female (ambiguous genitalia) or the genitalia appear completely female. The internal reproductive organs (gonads) are typically undeveloped and referred to as streak gonads. These abnormal gonads are nonfunctional and often become cancerous, so they are usually removed surgically early in life.  Affected females usually have normal genitalia and gonads and have only the kidney features of the condition. Because they do not have all the features of the condition, females are usually given the diagnosis of isolated nephrotic syndrome.
Question: What is (are) methemoglobinemia, beta-globin type ?

Answer: Methemoglobinemia, beta-globin type is a condition that affects the function of red blood cells. Specifically, it alters a molecule called hemoglobin within these cells. Hemoglobin within red blood cells attaches (binds) to oxygen molecules in the lungs, which it carries through the bloodstream, then releases in tissues throughout the body. Instead of normal hemoglobin, people with methemoglobinemia, beta-globin type have an abnormal form called methemoglobin, which is unable to efficiently deliver oxygen to the body's tissues. In methemoglobinemia, beta-globin type, the abnormal hemoglobin gives the blood a brown color. It also causes a bluish appearance of the skin, lips, and nails (cyanosis), which usually first appears around the age of 6 months. The signs and symptoms of methemoglobinemia, beta-globin type are generally limited to cyanosis, which does not cause any health problems. However, in rare cases, severe methemoglobinemia, beta-globin type can cause headaches, weakness, and fatigue.
Question: What are the genetic changes related to phenylketonuria ?

Answer: Mutations in the PAH gene cause phenylketonuria.  The PAH gene provides instructions for making an enzyme called phenylalanine hydroxylase. This enzyme converts the amino acid phenylalanine to other important compounds in the body. If gene mutations reduce the activity of phenylalanine hydroxylase, phenylalanine from the diet is not processed effectively. As a result, this amino acid can build up to toxic levels in the blood and other tissues. Because nerve cells in the brain are particularly sensitive to phenylalanine levels, excessive amounts of this substance can cause brain damage.  Classic PKU, the most severe form of the disorder, occurs when phenylalanine hydroxylase activity is severely reduced or absent. People with untreated classic PKU have levels of phenylalanine high enough to cause severe brain damage and other serious medical problems. Mutations in the PAH gene that allow the enzyme to retain some activity result in milder versions of this condition, such as variant PKU or non-PKU hyperphenylalaninemia.  Changes in other genes may influence the severity of PKU, but little is known about these additional genetic factors.
Question: What are the genetic changes related to fibrochondrogenesis ?

Answer: Fibrochondrogenesis can result from mutations in the COL11A1 or COL11A2 gene. These genes provide instructions for making components of type XI collagen, which is a complex molecule that gives structure and strength to the connective tissues that support the body's joints and organs. Specifically, type XI collagen is found in cartilage, a tough but flexible tissue that makes up much of the skeleton during early development. Most cartilage is later converted to bone, except for the cartilage that continues to cover and protect the ends of bones and is present in the nose and external ears. Type XI collagen is also part of the inner ear; the vitreous, which is the clear gel that fills the eyeball; and the nucleus pulposus, which is the center portion of the discs between vertebrae.  Mutations in the COL11A1 or COL11A2 gene impair the assembly of type XI collagen, in most cases leading to the production of abnormal collagen molecules. The defective collagen weakens connective tissues, impairing the formation of bones throughout the skeleton and causing changes in the eye and inner ear that lead to vision and hearing problems.
Question: What is (are) benign chronic pemphigus ?

Answer: Benign chronic pemphigus, often called Hailey-Hailey disease, is a rare skin condition that usually appears in early adulthood. The disorder is characterized by red, raw, and blistered areas of skin that occur most often in skin folds, such as the groin, armpits, neck, and under the breasts. These inflamed areas can become crusty or scaly and may itch and burn. The skin problems tend to worsen with exposure to moisture (such as sweat), friction, and hot weather.  The severity of benign chronic pemphigus varies from relatively mild episodes of skin irritation to widespread, persistent areas of raw and blistered skin that interfere with daily activities. Affected skin may become infected with bacteria or fungi, leading to pain and odor. Although the condition is described as "benign" (noncancerous), in rare cases the skin lesions may develop into a form of skin cancer called squamous cell carcinoma.  Many affected individuals also have white lines running the length of their fingernails. These lines do not cause any problems, but they can be useful for diagnosing benign chronic pemphigus.
Question: What causes Cystocele ?

Answer: A cystocele occurs when the muscles and supportive tissues between a womans bladder and vagina weaken and stretch, letting the bladder sag from its normal position and bulge into the vagina or through the vaginal opening. In a cystocele, the bladder tissue remains covered by the vaginal skin. A cystocele may result from damage to the muscles and tissues that hold the pelvic organs up inside the pelvis. A womans pelvic organs include the vagina, cervix, uterus, bladder, urethra, and small intestine. Damage to or weakening of the pelvic muscles and supportive tissues may occur after vaginal childbirth and with conditions that repeatedly strain or increase pressure in the pelvic area, such as
                
- repetitive straining for bowel movements  - constipation  - chronic or violent coughing  - heavy lifting  - being overweight or obese
                
A womans chances of developing a cystocele increase with age, possibly because of weakening muscles and supportive tissues from aging. Whether menopause increases a womans chances of developing a cystocele is unclear.
Question: What is (are) Colorectal Cancer ?

Answer: Several types of surgery are available for someone with colorectal cancer. If the cancer is found at a very early stage, the doctor may remove it without cutting through the abdominal wall. Instead, the doctor may put a tube up the rectum into the colon and cut the cancer out. This is called a local excision. If the cancer is found in a polyp, which is a small bulging piece of tissue, the operation is called a polypectomy. If the cancer is larger, the surgeon will remove the cancer and a small amount of healthy tissue around it. This is called a colectomy. The surgeon may then sew the healthy parts of the colon together. Usually, the surgeon will also remove lymph nodes near the colon and examine them under a microscope to see whether they contain cancer. If the doctor is not able to sew the two ends of the colon back together, an opening called a stoma is made on the abdomen for waste to pass out of the body before it reaches the rectum. This procedure is called a colostomy. Sometimes the colostomy is needed only until the lower colon has healed, and then it can be reversed. But if the doctor needs to remove the entire lower colon, the colostomy may be permanent.
Question: What are the symptoms of Wilms Tumor and Other Childhood Kidney Tumors ?

Answer: Signs of Wilms tumor and other childhood kidney tumors include a lump in the abdomen and blood in the urine. Sometimes childhood kidney tumors do not cause signs and symptoms and the parent finds a mass in the abdomen by chance or the mass is found during a well-child health check up. These and other signs and symptoms may be caused by kidney tumors or by other conditions. Check with your child's doctor if your child has any of the following:         - A lump, swelling, or pain in the abdomen.    - Blood in the urine.     -  High blood pressure (headache, feeling very tired, chest pain, or trouble seeing or breathing).    -  Hypercalcemia (loss of appetite, nausea and vomiting, weakness, or feeling very tired).    -  Fever for no known reason.    - Loss of appetite.    - Weight loss for no known reason.        Wilms tumor that has spread to the lungs or liver may cause the following signs and symptoms:         - Cough.    - Blood in the sputum.    - Trouble breathing.    - Pain in the abdomen.
Question: What is (are) Health Problems in Pregnancy ?

Answer: Every pregnancy has some risk of problems. The causes can be conditions you already have or conditions you develop. They also include being pregnant with more than one baby, previous problem pregnancies, or being over age 35. They can affect your health and the health of your baby.    If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Examples of common conditions that can complicate a pregnancy include       -  Heart disease     -  High blood pressure    -  Kidney problems    -  Autoimmune disorders    -  Sexually transmitted diseases    -  Diabetes    -  Cancer     - Infections        Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.    Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your doctor or midwife if something is bothering or worrying you.
Question: What is (are) Tumors and Pregnancy ?

Answer: Tumors during pregnancy are rare, but they can happen. Tumors can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. The most common cancers in pregnancy are breast cancer, cervical cancer, lymphoma, and melanoma. Cancer itself rarely harms the baby, and some cancer treatments are safe during pregnancy. You and your health care provider will work together to find the best treatment. Your options will depend on how far along the pregnancy is, as well as the type, size, and stage of your cancer.    Another type of tumor that women can get is called a gestational trophoblastic disease (GTD). It happens when a fertilized egg doesn't become a fetus. GTD is not always easy to find. It is usually benign, but some types can be malignant. The most common type of GTD is a molar pregnancy. In its early stages, it may look like a normal pregnancy. You should see your health care provider if you have vaginal bleeding (not menstrual bleeding).     Treatment depends on the type of tumor, whether it has spread to other places, and your overall health.
Question: What is (are) Scabies ?

Answer: Scabies is an itchy skin condition caused by the microscopic mite Sarcoptes scabei. It is common all over the world, and can affect anyone. Scabies spreads quickly in crowded conditions where there is frequent skin-to-skin contact between people. Hospitals, child-care centers, and nursing homes are examples. Scabies can easily infect sex partners and other household members. Sharing clothes, towels, and bedding can sometimes spread scabies. This can happen much more easily when the infested person has crusted scabies. You cannot get scabies from a pet. Pets get a different mite infection called mange.     Symptoms are       - Pimple-like irritations or a rash     - Intense itching, especially at night    - Sores caused by scratching        Your health care provider diagnoses scabies by looking at the skin rash and finding burrows in the skin.    Several lotions are available to treat scabies. The infected person's clothes, bedding and towels should be washed in hot water and dried in a hot dryer. Treatment is also recommended for household members and sexual partners.    Centers for Disease Control and Prevention
