Question: How to diagnose Chronic Lymphocytic Leukemia ?

Answer: Tests that examine the blood, bone marrow, and lymph nodes are used to detect (find) and diagnose chronic lymphocytic leukemia. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.     -   Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following:                -  The number of red blood cells and platelets.      - The number and type of white blood cells.      - The amount of hemoglobin (the protein that carries oxygen) in the red blood cells.      - The portion of the blood sample made up of red blood cells.              -   Immunophenotyping : A laboratory test in which the antigens or markers on the surface of a blood or bone marrow cell are checked to see if they are lymphocytes or myeloid cells. If the cells are malignant lymphocytes (cancer), they are checked to see if they are B lymphocytes or T lymphocytes.    -   FISH (fluorescence in situ hybridization): A laboratory technique used to look at genes or chromosomes in cells and tissues. Pieces of DNA that contain a fluorescent dye are made in the laboratory and added to cells or tissues on a glass slide. When these pieces of DNA bind to specific genes or areas of chromosomes on the slide, they light up when viewed under a microscope with a special light.     -   Flow cytometry : A laboratory test that measures the number of cells in a sample, the percentage of live cells in a sample, and certain characteristics of cells, such as size, shape, and the presence of tumor markers on the cell surface. The cells are stained with a light-sensitive dye, placed in a fluid, and passed in a stream before a laser or other type of light. The measurements are based on how the light-sensitive dye reacts to the light.    -   IgVH gene mutation test: A laboratory test done on a bone marrow or blood sample to check for an IgVH gene mutation. Patients with an IgVH gene mutation have a better prognosis.    -   Bone marrow aspiration and biopsy : The removal of bone marrow, blood, and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow, blood, and bone under a microscope to look for abnormal cells.
Question: What are the symptoms of Spinocerebellar ataxia 2 ?

Answer: What are the signs and symptoms of Spinocerebellar ataxia 2? Early symptoms of spinocerebellar ataxia may include uncoordinated movement (ataxia) and leg cramps. Other symptoms may include tremor; decreased muscle tone; poor tendon reflexes; abnormal eye movements; dementia; dystonia and/or chorea; muscle twitches; nerve irritation and swelling (polyneuropathy); leg weakness; difficulty swallowing; bladder dysfunction; and parkinsonism. The Human Phenotype Ontology provides the following list of signs and symptoms for Spinocerebellar ataxia 2. 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) Autosomal dominant inheritance - Bradykinesia - Dementia - Dilated fourth ventricle - Distal amyotrophy - Dysarthria - Dysdiadochokinesis - Dysmetria - Dysmetric saccades - Dysphagia - Fasciculations - Gaze-evoked nystagmus - Genetic anticipation - Hyporeflexia - Impaired horizontal smooth pursuit - Limb ataxia - Muscular hypotonia - Myoclonus - Oculomotor apraxia - Olivopontocerebellar atrophy - Ophthalmoplegia - Postural instability - Postural tremor - Progressive cerebellar ataxia - Rigidity - Rod-cone dystrophy - Slow saccadic eye movements - Spasticity - Spinocerebellar tract degeneration - Urinary bladder sphincter dysfunction - 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.
Question: How to diagnose High Blood Cholesterol ?

Answer: Your doctor will diagnose high blood cholesterol by checking the cholesterol levels in your blood. A blood test called a lipoprotein panel can measure your cholesterol levels. Before the test, youll need to fast (not eat or drink anything but water) for 9 to 12 hours.
                
The lipoprotein panel will give your doctor information about your:
                
Total cholesterol. Total cholesterol is a measure of the total amount of cholesterol in your blood, including low-density lipoprotein (LDL) cholesterol and high-density lipoprotein (HDL) cholesterol.
                
LDL cholesterol. LDL, or bad, cholesterol is the main source of cholesterol buildup and blockages in the arteries.
                
HDL cholesterol. HDL, or good, cholesterol helps remove cholesterol from your arteries.
                
Triglycerides (tri-GLIH-seh-rides). Triglycerides are a type of fat found in your blood. Some studies suggest that a high level of triglycerides in the blood may raise the risk of coronary heart disease, especially in women.
                
If its not possible to have a lipoprotein panel, knowing your total cholesterol and HDL cholesterol can give you a general idea about your cholesterol levels.
                
Testing for total and HDL cholesterol does not require fasting. If your total cholesterol is 200 mg/dL or more, or if your HDL cholesterol is less than 40 mg/dL, your doctor will likely recommend that you have a lipoprotein panel. (Cholesterol is measured as milligrams (mg) of cholesterol per deciliter (dL) of blood.)
                
The tables below show total, LDL, and HDL cholesterol levels and their corresponding categories. See how your cholesterol numbers compare to the numbers in the tables below.
                

                

                

                

                
Triglycerides also can raise your risk for heart disease. If your triglyceride level is borderline high (150199 mg/dL) or high (200 mg/dL or higher), you may need treatment.
                
Factors that can raise your triglyceride level include:
                
Overweight and obesity
                
Lack of physical activity
                
Cigarette smoking
                
Excessive alcohol use
                
A very high carbohydrate diet
                
Certain diseases and medicines
                
Some genetic disorders
Question: What is (are) Urinary Retention ?

Answer: The urinary tract is the bodys drainage system for removing urine, which is composed of wastes and extra fluid. In order for normal urination to occur, all body parts in the urinary tract need to work together in the correct order.
                
Kidneys. The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine. The kidneys work around the clock; a person does not control what they do.
                
Ureters. Ureters are the thin tubes of muscleone on each side of the bladderthat carry urine from each of the kidneys to the bladder.
                
Bladder. The bladder, located in the pelvis between the pelvic bones, is a hollow, muscular, balloon-shaped organ that expands as it fills with urine. Although a person does not control kidney function, a person does control when the bladder empties. Bladder emptying is known as urination. The bladder stores urine until the person finds an appropriate time and place to urinate. A normal bladder acts like a reservoir and can hold 1.5 to 2 cups of urine. How often a person needs to urinate depends on how quickly the kidneys produce the urine that fills the bladder. The muscles of the bladder wall remain relaxed while the bladder fills with urine. As the bladder fills to capacity, signals sent to the brain tell a person to find a toilet soon. During urination, the bladder empties through the urethra, located at the bottom of the bladder.
                
Three sets of muscles work together like a dam, keeping urine in the bladder.
                
The first set is the muscles of the urethra itself. The area where the urethra joins the bladder is the bladder neck. The bladder neck, composed of the second set of muscles known as the internal sphincter, helps urine stay in the bladder. The third set of muscles is the pelvic floor muscles, also referred to as the external sphincter, which surround and support the urethra.
                
To urinate, the brain signals the muscular bladder wall to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincters to relax. As the sphincters relax, urine exits the bladder through the urethra.

Question: What are the symptoms of Mnire's disease ?

Answer: What are the signs and symptoms of Mnire's disease? The symptoms of Mnire's disease typically occur suddenly and can arise daily, or as infrequently as once a year. Vertigo, often the most debilitating symptom of Mnire's disease, typically involves a whirling dizziness that forces the affected person to lie down. Vertigo attacks can lead to severe nausea, vomiting, and sweating, and often come with little or no warning. Some people with Mnire's disease have attacks that start with tinnitus (ear noises), a loss of hearing, or a full feeling or pressure in the affected ear. It is important to remember that all of these symptoms are unpredictable. Typically, the attack is characterized by a combination of vertigo, tinnitus, and hearing loss lasting several hours. People experience these discomforts at varying frequencies, durations, and intensities. Some may feel slight vertigo a few times a year. Others may be occasionally disturbed by intense, uncontrollable tinnitus while sleeping. Affected people may also notice hearing loss or feel unsteady for prolonged periods. Other occasional symptoms of Mnire's disease may include headaches, abdominal discomfort, and diarrhea. A person's hearing tends to recover between attacks but over time may become worse. Meniere's disease usually starts in one ear but it may extend to involve both ears over time. The Human Phenotype Ontology provides the following list of signs and symptoms for Mnire's disease. 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.

Question: What are the genetic changes related to Prader-Willi syndrome ?

Answer: Prader-Willi syndrome is caused by the loss of function of genes in a particular region of chromosome 15. People normally inherit one copy of this chromosome from each parent. Some genes are turned on (active) only on the copy that is inherited from a person's father (the paternal copy). This parent-specific gene activation is caused by a phenomenon called genomic imprinting.  Most cases of Prader-Willi syndrome (about 70 percent) occur when a segment of the paternal chromosome 15 is deleted in each cell. People with this chromosomal change are missing certain critical genes in this region because the genes on the paternal copy have been deleted, and the genes on the maternal copy are turned off (inactive). In another 25 percent of cases, a person with Prader-Willi syndrome has two copies of chromosome 15 inherited from his or her mother (maternal copies) instead of one copy from each parent. This phenomenon is called maternal uniparental disomy. Rarely, Prader-Willi syndrome can also be caused by a chromosomal rearrangement called a translocation, or by a mutation or other defect that abnormally turns off (inactivates) genes on the paternal chromosome 15.  It appears likely that the characteristic features of Prader-Willi syndrome result from the loss of function of several genes on chromosome 15. Among these are genes that provide instructions for making molecules called small nucleolar RNAs (snoRNAs). These molecules have a variety of functions, including helping to regulate other types of RNA molecules. (RNA molecules play essential roles in producing proteins and in other cell activities.) Studies suggest that the loss of a particular group of snoRNA genes, known as the SNORD116 cluster, may play a major role in causing the signs and symptoms of Prader-Willi syndrome. However, it is unknown how a missing SNORD116 cluster could contribute to intellectual disability, behavioral problems, and the physical features of the disorder.  In some people with Prader-Willi syndrome, the loss of a gene called OCA2 is associated with unusually fair skin and light-colored hair. The OCA2 gene is located on the segment of chromosome 15 that is often deleted in people with this disorder. However, loss of the OCA2 gene does not cause the other signs and symptoms of Prader-Willi syndrome. The protein produced from this gene helps determine the coloring (pigmentation) of the skin, hair, and eyes.  Researchers are studying other genes on chromosome 15 that may also be related to the major signs and symptoms of this condition.
Question: How to prevent Diabetes, Heart Disease, and Stroke ?

Answer: Even if you are at high risk for heart disease and stroke, you can help keep your heart and blood vessels healthy. You can do so by taking the following steps:
                
- Make sure that your diet is "heart-healthy." Meet with a registered dietitian to plan a diet that meets these goals:      - Include at least 14 grams of fiber daily for every 1,000 calories consumed. Foods high in fiber may help lower blood cholesterol. Oat bran, oatmeal, whole-grain breads and cereals, dried beans and peas (such as kidney beans, pinto beans, and black-eyed peas), fruits, and vegetables are all good sources of fiber. Increase the amount of fiber in your diet gradually to avoid digestive problems.    - Cut down on saturated fat. It raises your blood cholesterol level. Saturated fat is found in meats, poultry skin, butter, dairy products with fat, shortening, lard, and tropical oils such as palm and coconut oil. Your dietitian can figure out how many grams of saturated fat should be your daily maximum amount.    - Keep the cholesterol in your diet to less than 300 milligrams a day. Cholesterol is found in meat, dairy products, and eggs.    - Keep the amount of trans fat in your diet to a minimum. It's a type of fat in foods that raises blood cholesterol. Limit your intake of crackers, cookies, snack foods, commercially prepared baked goods, cake mixes, microwave popcorn, fried foods, salad dressings, and other foods made with partially hydrogenated oil. In addition, some kinds of vegetable shortening and margarines have trans fat. Check for trans fat in the Nutrition Facts section on the food package.    - If you smoke, quit. Your doctor can help you find ways to quit smoking.  - Ask your doctor whether you should take aspirin. Studies have shown that taking a low dose of aspirin every day can help reduce the risk of heart disease and stroke. However, aspirin is not safe for everyone. Your doctor can tell you whether taking aspirin is right for you and exactly how much to take.  - Get prompt treatment for transient ischemic attacks (TIAs). Early treatment for TIAs, sometimes called mini-strokes, may help prevent or delay a future stroke. Signs of a TIA are sudden weakness, loss of balance, numbness, confusion, blindness in one or both eyes, double vision, difficulty speaking, or a severe headache.
Question: What are the symptoms of Heart Attack ?

Answer: Symptoms Can Vary Not all heart attacks begin with the sudden, crushing chest pain that often is shown on TV or in the movies. The warning signs and symptoms of a heart attack aren't the same for everyone. Many heart attacks start slowly as mild pain or discomfort. Some people don't have symptoms at all. Heart attacks that occur without any symptoms or very mild symptoms are called silent heart attacks. However, some people may have a pattern of symptoms that recur. The more signs and symptoms you have, the more likely it is that you're having a heart attack If you have a second heart attack, your symptoms may not be the same as the first heart attack. Here are common signs and symptoms of a heart attack. Chest Pain or Discomfort The most common symptom of heart attack is chest pain or discomfort. Chest pain or discomfort that doesn't go away or changes from its usual pattern (for example, occurs more often or while you're resting) can be a sign of a heart attack. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain. It can be mild or severe. Heart attack pain can sometimes feel like indigestion or heartburn. All chest pain should be checked by a doctor. Other Upper Body Discomfort Discomfort can also occur in other areas of the upper body, including pain or numbness in one or both arms, the back, neck, jaw or stomach. Shortness of Breath Shortness of breath often happens along with, or before chest discomfort. Other Symptoms Other symptoms may include - breaking out in a cold sweat   - having nausea and vomiting   - feeling light-headed or dizzy   - fainting   - sleep problems   - fatigue   - lack of energy.  breaking out in a cold sweat having nausea and vomiting feeling light-headed or dizzy fainting sleep problems fatigue lack of energy. Angina or a Heart Attack? Angina is chest pain or discomfort that occurs if an area of your heart muscle doesn't get enough oxygen-rich blood. Angina occurs in people who have coronary heart disease, usually when they're active. Angina symptoms can be very similar to heart attack symptoms. Angina pain usually lasts for only a few minutes and goes away with rest. If you think you may be having a heart attack, or if your angina pain does not go away as usual when you take your angina medication as directed, call 9-1-1 for help. You can begin to receive life saving treatment in the ambulance on the way to the emergency room.
