Question: What are the symptoms of Polyhydramnios, megalencephaly, and symptomatic epilepsy syndrome ?

Answer: What are the signs and symptoms of Polyhydramnios, megalencephaly, and symptomatic epilepsy syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Polyhydramnios, megalencephaly, and symptomatic epilepsy syndrome. 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) Hyperplasia of midface 16/16 Hypertelorism 16/16 Large forehead 16/16 Long face 16/16 Muscular hypotonia 16/16 Polyhydramnios 16/16 Thick lower lip vermilion 16/16 Thick upper lip vermilion 16/16 Wide mouth 16/16 Wide nasal bridge 16/16 Macrocephaly 15/16 Premature birth 15/16 Atria septal defect 4/16 Diabetes insipidus 2/16 Nephrocalcinosis 2/16 Autosomal recessive 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.
Question: What is (are) Acute Disseminated Encephalomyelitis ?

Answer: Acute disseminated encephalomyelitis (ADEM) is characterized by a brief but widespread attack of inflammation in the brain and spinal cord that damages myelin  the protective covering of nerve fibers. ADEM often follows viral or bacterial infections, or less often, vaccination for measles, mumps, or rubella. The symptoms of ADEM appear rapidly, beginning with encephalitis-like symptoms such as fever, fatigue, headache, nausea and vomiting, and in the most severe cases, seizures and coma. ADEM typically damages white matter (brain tissue that takes its name from the white color of myelin), leading to neurological symptoms such as visual loss (due to inflammation of the optic nerve)in one or both eyes, weakness even to the point of paralysis, and difficulty coordinating voluntary muscle movements (such as those used in walking). ADEM is sometimes misdiagnosed as a severe first attack of multiple sclerosis (MS), since the symptoms and the appearance of the white matter injury on brain imaging may be similar. However, ADEM has several features which differentiate it from MS. First, unlike MS patients, persons with ADEM will have rapid onset of fever, a history of recent infection or immunization, and some degree of impairment of consciousness, perhaps even coma; these features are not typically seen in MS. Children are more likely than adults to have ADEM, whereas MS is a rare diagnosis in children. In addition, ADEM usually consists of a single episode or attack of widespread myelin damage, while MS features many attacks over the course of time. Doctors will often use imaging techniques, such as MRI (magnetic resonance imaging), to search for old and new lesions (areas of damage) on the brain. The presence of older brain lesions on MRI suggest that the condition may be MS rather than ADEM, since MS can cause brain lesions before symptoms become obvious. In rare situations, a brain biopsy may be necessary to differentiate between ADEM and some other diseases that involve inflammation and damage to myelin..
Question: What are the genetic changes related to Brugada syndrome ?

Answer: Brugada syndrome can be caused by mutations in one of several genes. The most commonly mutated gene in this condition is SCN5A, which is altered in approximately 30 percent of affected individuals. This gene provides instructions for making a sodium channel, which normally transports positively charged sodium atoms (ions) into heart muscle cells. This type of ion channel plays a critical role in maintaining the heart's normal rhythm. Mutations in the SCN5A gene alter the structure or function of the channel, which reduces the flow of sodium ions into cells. A disruption in ion transport alters the way the heart beats, leading to the abnormal heart rhythm characteristic of Brugada syndrome.  Mutations in other genes can also cause Brugada syndrome. Together, these other genetic changes account for less than two percent of cases of the condition. Some of the additional genes involved in Brugada syndrome provide instructions for making proteins that ensure the correct location or function of sodium channels in heart muscle cells. Proteins produced by other genes involved in the condition form or help regulate ion channels that transport calcium or potassium into or out of heart muscle cells. As with sodium channels, proper flow of ions through calcium and potassium channels in the heart muscle helps maintain a regular heartbeat. Mutations in these genes disrupt the flow of ions, impairing the heart's normal rhythm.  In affected people without an identified gene mutation, the cause of Brugada syndrome is often unknown. In some cases, certain drugs may cause a nongenetic (acquired) form of the disorder. Drugs that can induce an altered heart rhythm include medications used to treat some forms of arrhythmia, a condition called angina (which causes chest pain), high blood pressure, depression, and other mental illnesses. Abnormally high blood levels of calcium (hypercalcemia) or potassium (hyperkalemia), as well as unusually low potassium levels (hypokalemia), also have been associated with acquired Brugada syndrome. In addition to causing a nongenetic form of this disorder, these factors may trigger symptoms in people with an underlying mutation in SCN5A or another gene.
Question: How to prevent Diarrhea ?

Answer: Two types of diarrhea can be preventedrotavirus diarrhea and travelers diarrhea.
                
Rotavirus Diarrhea
                
Two oral vaccines have been approved by the U.S. Food and Drug Administration to protect children from rotavirus infections: rotavirus vaccine, live, oral, pentavalent (RotaTeq); and rotavirus vaccine, live, oral (Rotarix). RotaTeq is given to infants in three doses at 2, 4, and 6 months of age. Rotarix is given in two doses. The first dose is given when infants are 6 weeks old, and the second is given at least 4 weeks later but before infants are 24 weeks old.
                
Parents of infants should discuss rotavirus vaccination with a health care provider. For more information, parents can visit the Centers for Disease Control and Prevention rotavirus vaccination webpage at www.cdc.gov/vaccines/vpd-vac/rotavirus.
                
Travelers Diarrhea
                
To prevent travelers diarrhea, people traveling from the United States to developing countries should avoid
                
- drinking tap water, using tap water to brush their teeth, or using ice made from tap water  - drinking unpasteurized milk or milk products  - eating raw fruits and vegetables, including lettuce and fruit salads, unless they peel the fruits or vegetables themselves  - eating raw or rare meat and fish  - eating meat or shellfish that is not hot when served  - eating food from street vendors
                
Travelers can drink bottled water, soft drinks, and hot drinks such as coffee or tea.
                
People concerned about travelers diarrhea should talk with a health care provider before traveling. The health care provider may recommend that travelers bring medicine with them in case they develop diarrhea during their trip. Health care providers may advise some peopleespecially people with weakened immune systemsto take antibiotics before and during a trip to help prevent travelers diarrhea. Early treatment with antibiotics can shorten a bout of travelers diarrhea.
Question: How to diagnose IgA Nephropathy ?

Answer: A health care provider diagnoses kidney disease with
                
- a medical and family history  - a physical exam  - urine tests   - a blood test
                
Medical and Family History
                
Taking a medical and family history may help a health care provider diagnose kidney disease.
                
Physical Exam
                
A physical exam may help diagnose kidney disease. During a physical exam, a health care provider usually
                
- measures the patients blood pressure  - examines the patients body for swelling
                
Urine Tests
                
Dipstick test for albumin and blood. A dipstick test performed on a urine sample can detect the presence of albumin and blood. The patient provides a urine sample in a special container in a health care providers office or a commercial facility. A nurse or technician can test the sample in the same location, or he or she can send it to a lab for analysis. The test involves placing a strip of chemically treated paper, called a dipstick, into the patients urine sample. Patches on the dipstick change color when albumin or blood is present in urine.
                
Urine albumin-to-creatinine ratio. A health care provider uses this measurement, which compares the amount of albumin with the amount of creatinine in a urine sample, to estimate 24-hour albumin excretion. A patient may have chronic kidney disease if the urine albumin-to-creatinine ratio is greater than 30 milligrams (mg) of albumin for each gram (g) of creatinine (30 mg/g). This measurement is also called UACR.
                
Blood Test
                
A blood test involves having blood drawn at a health care providers office or a commercial facility and sending the sample to a lab for analysis. A health care provider may order a blood test to estimate how much blood a patients kidneys filter each minutea measurement called the estimated glomerular filtration rate (eGFR). Depending on the results, the test can indicate the following:
                
- eGFR of 60 or above is in the normal range  - eGFR below 60 may indicate kidney disease  - eGFR of 15 or below may indicate kidney failure
Question: What is (are) Amyloidosis and Kidney Disease ?

Answer: Primary amyloidosis and dialysis-related amyloidosis are the types of amyloidosis that can affect the kidneys.
                
Primary Amyloidosis of the Kidneys
                
The kidneys are the organs most commonly affected by primary amyloidosis. Amyloid deposits damage the kidneys and make it harder for them to filter wastes and break down proteins. When the kidneys become too damaged, they may no longer be able to function well enough to maintain health, resulting in kidney failure. Kidney failure can lead to problems such as high blood pressure, bone disease, and anemiaa condition in which the body has fewer red blood cells than normal.
                
Dialysis-related Amyloidosis
                
People who suffer from kidney failure and have been on long-term dialysis may develop dialysis-related amyloidosis. This type of amyloidosis occurs when a certain protein, called beta-2 microglobulin, builds up in the blood because dialysis does not remove it completely. The two types of dialysis are
                
- hemodialysis. Hemodialysis uses a special filter called a dialyzer to remove wastes and extra fluid from the blood.  - peritoneal dialysis. Peritoneal dialysis uses the lining of the abdominal cavitythe space in the body that holds organs such as the stomach, intestines, and liverto filter the blood.
                
Dialysis-related amyloidosis is a complication of kidney failure because neither hemodialysis nor peritoneal dialysis effectively filters beta-2 microglobulin from the blood. As a result, elevated amounts of beta-2 microglobulin remain in the blood. Dialysis-related amyloidosis is relatively common in people with kidney failure, especially adults older than 60 years of age, who have been on dialysis for more than 5 years.1

Question: How to prevent Prevent diabetes problems: Keep your diabetes under control ?

Answer: You can take steps each day to prevent diabetes problems.
                
Steps          Healthy Eating                     - Follow the healthy eating plan that you and your doctor or dietitian have made.      - Learn what to eat to keep your blood glucose levels under control.      - Make wise food choices to help you feel good every day and to lose weight if needed.            Blood Glucose                     - Check your blood glucose every day.      - Each time you check your blood glucose, write the number in a record book to share with your health care team.      - Treat low blood glucose quickly.            Physical Activity                     - Even small amounts of physical activity help manage diabetes. Aim for 30 to 60 minutes of physical activity most days of the week. Children and adolescents with type 2 diabetes who are 10 to 17 years old should aim for 60 minutes of activity every day.      - Not all physical activity has to take place at the same time.      - Do aerobic activities, such as brisk walking, which use your large muscles to make your heart beat faster. The large muscles are those of the upper and lower arms and legs and those that control head, shoulder, and hip movements.      - Do activities to strengthen muscles and bone, such as lifting weights or sit-ups. Aim for two times a week.      - Stretch to increase your flexibility, lower stress, and help prevent muscle soreness after physical activity.      - Increase daily activity by decreasing time spent watching TV or at the computer. Children and adolescents should limit screen time not related to school to less than 2 hours per day. Limiting screen time can help you meet your physical activity goal.      - Always talk with your doctor before you start a new physical activity program.            Medicines                     - Take your medicines as directed, including insulin if ordered by your doctor.            Feet                     - Check your feet every day for cuts, blisters, sores, swelling, redness, or sore toenails.            Mouth                     - Brush and floss your teeth every day.            Blood Pressure                     - Control your blood pressure and cholesterol.            Smoking                     - Dont smoke.
Question: What is (are) Metastatic Squamous Neck Cancer with Occult Primary ?

Answer: Key Points
                    - Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body.    - Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat.     - Tests that examine the tissues of the neck, respiratory tract, and upper part of the digestive tract are used to detect (find) and diagnose metastatic squamous neck cancer and the primary tumor.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body.
                    Squamous cells are thin, flat cells found in tissues that form the surface of the skin and the lining of body cavities such as the mouth, hollow organs such as the uterus and blood vessels, and the lining of the respiratory (breathing) and digestive tracts. Some organs with squamous cells are the esophagus, lungs, kidneys, and uterus. Cancer can begin in squamous cells anywhere in the body and metastasize (spread) through the blood or lymph system to other parts of the body.    When squamous cell cancer spreads to lymph nodes in the neck or around the collarbone, it is called metastatic squamous neck cancer. The doctor will try to find the primary tumor (the cancer that first formed in the body), because treatment for metastatic cancer is the same as treatment for the primary tumor. For example, when lung cancer spreads to the neck, the cancer cells in the neck are lung cancer cells and they are treated the same as the cancer in the lung. Sometimes doctors cannot find where in the body the cancer first began to grow. When tests cannot find a primary tumor, it is called an occult (hidden) primary tumor. In many cases, the primary tumor is never found.
Question: What is (are) Colorectal Cancer ?

Answer: Key Points
                    - Colorectal cancer is a disease in which malignant (cancer) cells form in the tissues of the colon or the rectum.     - Colorectal cancer is the second leading cause of death from cancer in the United States.     - Different factors increase or decrease the risk of getting colorectal cancer.
                
                
                    Colorectal cancer is a disease in which malignant (cancer) cells form in the tissues of the colon or the rectum.
                    The colon and rectum are parts of the body's digestive system. The digestive system removes and processes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from foods and helps pass waste material out of the body. The digestive system is made up of the mouth, throat, esophagus, stomach, and the small and large intestines. The colon (large bowel) is the first part of the large intestine and is about 5 feet long. Together, the rectum and anal canal make up the last part of the large intestine and are 6-8 inches long. The anal canal ends at the anus (the opening of the large intestine to the outside of the body).      Cancer that begins in the colon is called colon cancer, and cancer that begins in the rectum is called rectal cancer. Cancer that begins in either of these organs may also be called colorectal cancer.   See the following PDQ summaries for more information about colorectal cancer:         -   Colorectal Cancer Prevention     -  Colon Cancer Treatment     -  Rectal Cancer Treatment     -  Genetics of Colorectal Cancer
                
                
                    Colorectal cancer is the second leading cause of death from cancer in the United States.
                    The number of new colorectal cancer cases and the number of deaths from colorectal cancer are decreasing a little bit each year. But in adults younger than 50 years, there has been a small increase in the number of new cases each year since 1998. Colorectal cancer is found more often in men than in women.
