### Question: What are the stages of Prostate Cancer ? ### Response:

Key Points - After prostate cancer has been diagnosed, tests are done to find out if cancer cells have spread within the prostate 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 prostate cancer: - Stage I - Stage II - Stage III - Stage IV After prostate cancer has been diagnosed, tests are done to find out if cancer cells have spread within the prostate or to other parts of the body. The process used to find out if cancer has spread within the prostate 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 prostate cancer are often also used to stage the disease. (See the General Information section.) In prostate cancer, staging tests may not be done unless the patient has symptoms or signs that the cancer has spread, such as bone pain, a high PSA level, or a high Gleason score. The following tests and procedures also may be used in the staging process: - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - Pelvic lymphadenectomy : A surgical procedure to remove the lymph nodes in the pelvis. A pathologist views the tissue under a microscope to look for cancer cells. - Seminal vesicle biopsy : The removal of fluid from the seminal vesicles (glands that make semen) using a needle. A pathologist views the fluid under a microscope to look for cancer cells. - ProstaScint scan : A procedure to check for cancer that has spread from the prostate to other parts of the body, such as the lymph nodes. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material attaches to prostate cancer cells and is detected by a scanner. The radioactive material shows up as a bright spot on the picture in areas where there are a lot of prostate cancer cells. The stage of the cancer is based on the results of the staging and diagnostic tests, including the prostate-specific antigen (PSA) test and the Gleason score. The tissue samples removed during the biopsy are used to find out the Gleason score. The Gleason score ranges from 2-10 and describes how different the cancer cells look from normal cells and how likely it is that the tumor will spread. The lower the number, the less likely the tumor is to spread. 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 prostate cancer spreads to the bone, the cancer cells in the bone are actually prostate cancer cells. The disease is metastatic prostate cancer, not bone cancer. Denosumab, a monoclonal antibody, may be used to prevent bone metastases. The following stages are used for prostate cancer: Stage I In stage I, cancer is found in the prostate only. The cancer: - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is lower than 10 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is lower than 10 and the Gleason score is 6 or lower; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. Cancer is found in one-half or less of one lobe of the prostate. The PSA level and the Gleason score are not known. Stage II In stage II, cancer is more advanced than in stage I, but has not spread outside the prostate. Stage II is divided into stages IIA and IIB. In stage IIA, cancer: - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is lower than 20 and the Gleason score is 7; or - is found by needle biopsy (done for a high PSA level) or in a small amount of tissue during surgery for other reasons (such as benign prostatic hyperplasia). The PSA level is at least 10 but lower than 20 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is at least 10 but lower than 20 and the Gleason score is 6 or lower; or - is found in one-half or less of one lobe of the prostate. The PSA level is lower than 20 and the Gleason score is 7; or - is found in more than one-half of one lobe of the prostate. In stage IIB, cancer: - is found in opposite sides of the prostate. The PSA can be any level and the Gleason score can range from 2 to 10; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. The PSA level is 20 or higher and the Gleason score can range from 2 to 10; or - cannot be felt during a digital rectal exam and cannot be seen in imaging tests. The PSA can be any level and the Gleason score is 8 or higher. Stage III In stage III, cancer has spread beyond the outer layer of the prostate and may have spread to the seminal vesicles. The PSA can be any level and the Gleason score can range from 2 to 10. Stage IV In stage IV, the PSA can be any level and the Gleason score can range from 2 to 10. Also, cancer: - has spread beyond the seminal vesicles to nearby tissue or organs, such as the rectum, bladder, or pelvic wall; or - may have spread to the seminal vesicles or to nearby tissue or organs, such as the rectum, bladder, or pelvic wall. Cancer has spread to nearby lymph nodes; or - has spread to distant parts of the body, which may include lymph nodes or bones. Prostate cancer often spreads to the bones.

### Question: What are the treatments for Merkel Cell Carcinoma ? ### Response:

Key Points - There are different types of treatment for patients with Merkel cell carcinoma. - Three types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - New types of treatment are being tested in clinical trials. - Treatment for Merkel cell carcinoma may cause side effects. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with Merkel cell carcinoma. Different types of treatments are available for patients with Merkel cell carcinoma. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Three types of standard treatment are used: Surgery One or more of the following surgical procedures may be used to treat Merkel cell carcinoma: - Wide local excision: The cancer is cut from the skin along with some of the tissue around it. A sentinel lymph node biopsy may be done during the wide local excision procedure. If there is cancer in the lymph nodes, a lymph node dissection also may be done. - Lymph node dissection: A surgical procedure in which the lymph nodes are removed and a sample of tissue is checked under a microscope for signs of cancer. For a regional lymph node dissection, some of the lymph nodes in the tumor area are removed; for a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymphadenectomy. Even if the doctor removes all the cancer that can be seen at the time of the surgery, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat Merkel cell carcinoma, and may also be used as palliative therapy to relieve symptoms and improve quality of life. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping the cells from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. New types of treatment are being tested in clinical trials. Treatment for Merkel cell carcinoma may cause side effects. For information about side effects caused by treatment for cancer, see our Side Effects page. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options by Stage Stage I and Stage II Merkel Cell Carcinoma Treatment of stage I and stage II Merkel cell carcinoma may include the following: - Surgery to remove the tumor, such as wide local excision with or without lymph node dissection. - Radiation therapy after surgery. - A clinical trial of a new treatment. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage I neuroendocrine carcinoma of the skin and stage II neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Stage III Merkel Cell Carcinoma Treatment of stage III Merkel cell carcinoma may include the following: - Wide local excision with or without lymph node dissection. - Radiation therapy. - A clinical trial of chemotherapy. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage III neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Stage IV Merkel Cell Carcinoma Treatment of stage IV Merkel cell carcinoma may include the following as palliative treatment to relieve symptoms and improve quality of life: - Chemotherapy. - Surgery. - Radiation therapy. - A clinical trial of a new treatment. Check the list of NCI-supported cancer clinical trials that are now accepting patients with stage IV neuroendocrine carcinoma of the skin. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website.

### Question: How to prevent Colorectal Cancer ? ### Response:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following risk factors increase the risk of colorectal cancer: - Age - Family history of colorectal cancer - Personal history - Inherited risk - Alcohol - Cigarette smoking - Obesity - The following protective factors decrease the risk of colorectal cancer: - Physical activity - Aspirin - Combination hormone replacement therapy - Polyp removal - It is not clear if the following affect the risk of colorectal cancer: - Nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin - Calcium - Diet - The following factors do not affect the risk of colorectal cancer: - Hormone replacement therapy with estrogen only - Statins - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent colorectal cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. The following risk factors increase the risk of colorectal cancer: Age The risk of colorectal cancer increases after age 50. Most cases of colorectal cancer are diagnosed after age 50. Family history of colorectal cancer Having a parent, brother, sister, or child with colorectal cancer doubles a person's risk of colorectal cancer. Personal history Having a personal history of the following conditions increases the risk of colorectal cancer: - Previous colorectal cancer. - High-risk adenomas (colorectal polyps that are 1 centimeter or larger in size or that have cells that look abnormal under a microscope). - Ovarian cancer. - Inflammatory bowel disease (such as ulcerative colitis or Crohn disease). Inherited risk The risk of colorectal cancer is increased when certain gene changes linked to familial adenomatous polyposis (FAP) or hereditary nonpolyposis colon cancer (HNPCC or Lynch Syndrome) are inherited. Alcohol Drinking 3 or more alcoholic beverages per day increases the risk of colorectal cancer. Drinking alcohol is also linked to the risk of forming large colorectal adenomas (benign tumors). Cigarette smoking Cigarette smoking is linked to an increased risk of colorectal cancer and death from colorectal cancer. Smoking cigarettes is also linked to an increased risk of forming colorectal adenomas. Cigarette smokers who have had surgery to remove colorectal adenomas are at an increased risk for the adenomas to recur (come back). Obesity Obesity is linked to an increased risk of colorectal cancer and death from colorectal cancer. The following protective factors decrease the risk of colorectal cancer: Physical activity A lifestyle that includes regular physical activity is linked to a decreased risk of colorectal cancer. Aspirin Studies have shown that taking aspirin lowers the risk of colorectal cancer and the risk of death from colorectal cancer. The decrease in risk begins 10 to 20 years after patients start taking aspirin. The possible harms of aspirin use (100 mg or less) daily or every other day include an increased risk of stroke and bleeding in the stomach and intestines. These risks may be greater among the elderly, men, and those with conditions linked to a higher than normal risk of bleeding. Combination hormone replacement therapy Studies have shown that combination hormone replacement therapy (HRT) that includes both estrogen and progestin lowers the risk of invasive colorectal cancer in postmenopausal women. However, in women who take combination HRT and do develop colorectal cancer, the cancer is more likely to be advanced when it is diagnosed and the risk of dying from colorectal cancer is not decreased. The possible harms of combination HRT include an increased risk of having: - Breast cancer. - Heart disease. - Blood clots. Polyp removal Most colorectal polyps are adenomas, which may develop into cancer. Removing colorectal polyps that are larger than 1 centimeter (pea-sized) may lower the risk of colorectal cancer. It is not known if removing smaller polyps lowers the risk of colorectal cancer. The possible harms of polyp removal during colonoscopy or sigmoidoscopy include a tear in the wall of the colon and bleeding. It is not clear if the following affect the risk of colorectal cancer: Nonsteroidal anti-inflammatory drugs (NSAIDs) other than aspirin It is not known if the use of nonsteroidal anti-inflammatory drugs or NSAIDs (such as sulindac, celecoxib, naproxen, and ibuprofen) lowers the risk of colorectal cancer. Studies have shown that taking the nonsteroidal anti-inflammatory drug celecoxib reduces the risk of colorectal adenomas (benign tumors) coming back after they have been removed. It is not clear if this results in a lower risk of colorectal cancer. Taking sulindac or celecoxib has been shown to reduce the number and size of polyps that form in the colon and rectum of people with familial adenomatous polyposis (FAP). It is not clear if this results in a lower risk of colorectal cancer. The possible harms of NSAIDs include: - Kidney problems. - Bleeding in the stomach, intestines, or brain. - Heart problems such as heart attack and congestive heart failure. Calcium It is not known if taking calcium supplements lowers the risk of colorectal cancer. Diet It is not known if a diet low in fat and meat and high in fiber, fruits, and vegetables lowers the risk of colorectal cancer. Some studies have shown that a diet high in fat, proteins, calories, and meat increases the risk of colorectal cancer, but other studies have not. The following factors do not affect the risk of colorectal cancer: Hormone replacement therapy with estrogen only Hormone replacement therapy with estrogen only does not lower the risk of having invasive colorectal cancer or the risk of dying from colorectal cancer. Statins Studies have shown that taking statins (drugs that lower cholesterol) does not increase or decrease the risk of colorectal cancer. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include exercising more or quitting smoking or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent colorectal cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for colon cancer prevention trials or rectal cancer prevention trials that are now accepting patients.

### Question: What are the treatments for Male Breast Cancer ? ### Response:

Key Points - There are different types of treatment for men with breast cancer. - Five types of standard treatment are used to treat men with breast cancer: - Surgery - Chemotherapy - Hormone therapy - Radiation therapy - Targeted therapy - Treatment for male breast cancer may cause side effects. There are different types of treatment for men with breast cancer. Different types of treatment are available for men with breast cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. For some patients, taking part in a clinical trial may be the best treatment choice. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. Information about clinical trials is available from the NCI website. Choosing the most appropriate cancer treatment is a decision that ideally involves the patient, family, and health care team. Five types of standard treatment are used to treat men with breast cancer: Surgery Surgery for men with breast cancer is usually a modified radical mastectomy (removal of the breast, many of the lymph nodes under the arm, the lining over the chest muscles, and sometimes part of the chest wall muscles). Breast-conserving surgery, an operation to remove the cancer but not the breast itself, is also used for some men with breast cancer. A lumpectomy is done to remove the tumor (lump) and a small amount of normal tissue around it. Radiation therapy is given after surgery to kill any cancer cells that are left. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Breast Cancer for more information. Hormone therapy Hormone therapy is a cancer treatment that removes hormones or blocks their action and stops cancer cells from growing. Hormones are substances made by glands in the body and circulated in the bloodstream. Some hormones can cause certain cancers to grow. If tests show that the cancer cells have places where hormones can attach (receptors), drugs, surgery, or radiation therapy is used to reduce the production of hormones or block them from working. See Drugs Approved for Breast Cancer for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat male breast cancer. Targeted therapy Targeted therapy is a type of treatment that uses drugs or other substances to identify and attack specific cancer cells without harming normal cells. Monoclonal antibody therapy is a type of targeted therapy used to treat men with breast cancer. Monoclonal antibody therapy uses antibodies made in the laboratory from a single type of immune system cell. These antibodies can identify substances on cancer cells or normal substances that may help cancer cells grow. The antibodies attach to the substances and kill the cancer cells, block their growth, or keep them from spreading. Monoclonal antibodies are given by infusion. They may be used alone or to carry drugs, toxins, or radioactive material directly to cancer cells. Monoclonal antibodies are also used with chemotherapy as adjuvant therapy (treatment given after surgery to lower the risk that the cancer will come back). Trastuzumab is a monoclonal antibody that blocks the effects of the growth factor protein HER2. See Drugs Approved for Breast Cancer for more information. Treatment for male breast cancer may cause side effects. For information about side effects caused by treatment for cancer, see our Side Effects page. Treatment Options for Male Breast Cancer Initial Surgery Treatment for men diagnosed with breast cancer is usually modified radical mastectomy. Breast-conserving surgery with lumpectomy may be used for some men. Adjuvant Therapy Therapy given after an operation when cancer cells can no longer be seen is called adjuvant therapy. Even if the doctor removes all the cancer that can be seen at the time of the operation, the patient may be given radiation therapy, chemotherapy, hormone therapy, and/or targeted therapy after surgery, to try to kill any cancer cells that may be left. - Node-negative: For men whose cancer is node-negative (cancer has not spread to the lymph nodes), adjuvant therapy should be considered on the same basis as for a woman with breast cancer because there is no evidence that response to therapy is different for men and women. - Node-positive: For men whose cancer is node-positive (cancer has spread to the lymph nodes), adjuvant therapy may include the following: - Chemotherapy plus tamoxifen (to block the effect of estrogen). - Other hormone therapy. - Targeted therapy with a monoclonal antibody (trastuzumab). These treatments appear to increase survival in men as they do in women. The patients response to hormone therapy depends on whether there are hormone receptors (proteins) in the tumor. Most breast cancers in men have these receptors. Hormone therapy is usually recommended for male breast cancer patients, but it can have many side effects, including hot flashes and impotence (the inability to have an erection adequate for sexual intercourse). Distant Metastases Treatment for men with distant metastases (cancer that has spread to other parts of the body) may be hormone therapy, chemotherapy, or both. Hormone therapy may include the following: - Orchiectomy (the removal of the testicles to decrease the amount of hormone made). - Luteinizing hormone-releasing hormone agonist with or without total androgen blockade (to decrease the the amount of sex hormones made). - Tamoxifen for cancer that is estrogen-receptor positive. - Progestin (a female hormone made in a laboratory). - Aromatase inhibitors (to decrease the amount of estrogen made). Hormone therapies may be used in sequence (one after the other). Standard chemotherapy regimens may be used if hormone therapy does not work. Men usually respond to therapy in the same way as women who have breast cancer.

### Question: How to diagnose Zollinger-Ellison Syndrome ? ### Response:

A health care provider diagnoses Zollinger-Ellison syndrome based on the following: - medical history - physical exam - signs and symptoms - blood tests - upper gastrointestinal (GI) endoscopy - imaging tests to look for gastrinomas - measurement of stomach acid Medical History Taking a medical and family history is one of the first things a health care provider may do to help diagnose Zollinger-Ellison syndrome. The health care provider may ask about family cases of MEN1 in particular. Physical Exam A physical exam may help diagnose Zollinger-Ellison syndrome. During a physical exam, a health care provider usually - examines a persons body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the persons body Signs and Symptoms A health care provider may suspect Zollinger-Ellison syndrome if - diarrhea accompanies peptic ulcer symptoms or if peptic ulcer treatment fails. - a person has peptic ulcers without the use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen or a bacterial Helicobacter pylori (H. pylori) infection. NSAID use and H. pylori infection may cause peptic ulcers. - a person has severe ulcers that bleed or cause holes in the duodenum or stomach. - a health care provider diagnoses a person or the persons family member with MEN1 or a person has symptoms of MEN1. Blood Tests The health care provider may use blood tests to check for an elevated gastrin level. A technician or nurse draws a blood sample during an office visit or at a commercial facility and sends the sample to a lab for analysis. A health care provider will ask the person to fast for several hours prior to the test and may ask the person to stop acid-reducing medications for a period of time before the test. A gastrin level that is 10 times higher than normal suggests Zollinger-Ellison syndrome.2 A health care provider may also check for an elevated gastrin level after an infusion of secretin. Secretin is a hormone that causes gastrinomas to release more gastrin. A technician or nurse places an intravenous (IV) needle in a vein in the arm to give an infusion of secretin. A health care provider may suspect Zollinger-Ellison syndrome if blood drawn after the infusion shows an elevated gastrin level. Upper Gastrointestinal Endoscopy The health care provider uses an upper GI endoscopy to check the esophagus, stomach, and duodenum for ulcers and esophagitisa general term used to describe irritation and swelling of the esophagus. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenum. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. The gastroenterologist carefully feeds the endoscope down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. A technician or nurse inserts an IV needle in a vein in the arm if anesthesia is given. Imaging Tests To help find gastrinomas, a health care provider may order one or more of the following imaging tests: - Computerized tomography (CT) scan. A CT scan is an x ray that produces pictures of the body. A CT scan may include the injection of a special dye, called contrast medium. CT scans use a combination of x rays and computer technology to create images. CT scans require the person to lie on a table that slides into a tunnel-shaped device where an x-ray technician takes x rays. A computer puts the different views together to create a model of the pancreas, stomach, and duodenum. The x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images. The person does not need anesthesia. CT scans can show tumors and ulcers. - Magnetic resonance imaging (MRI). MRI is a test that takes pictures of the bodys internal organs and soft tissues without using x rays. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The person does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. An MRI may include the injection of contrast medium. With most MRI machines, the person will lie on a table that slides into a tunnel-shaped device that may be open ended or closed at one end. Some machines allow the person to lie in a more open space. During an MRI, the person, although usually awake, remains perfectly still while the technician takes the images, which usually takes only a few minutes. The technician will take a sequence of images from different angles to create a detailed picture of the upper GI tract. During sequencing, the person will hear loud mechanical knocking and humming noises. - Endoscopic ultrasound. This procedure involves using a special endoscope called an endoechoscope to perform ultrasound of the pancreas. The endoechoscope has a built-in miniature ultrasound probe that bounces safe, painless sound waves off organs to create an image of their structure. A gastroenterologist performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The gastroenterologist carefully feeds the endoechoscope down the esophagus, through the stomach and duodenum, until it is near the pancreas. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. A sedative helps the person stay relaxed and comfortable. The images can show gastrinomas in the pancreas. - Angiogram. An angiogram is a special kind of x ray in which an interventional radiologista specially trained radiologistthreads a thin, flexible tube called a catheter through the large arteries, often from the groin, to the artery of interest. The radiologist injects contrast medium through the catheter so the images show up more clearly on the x ray. The interventional radiologist performs the procedure and interprets the images in a hospital or an outpatient center. A person does not need anesthesia, though a light sedative may help reduce a persons anxiety during the procedure. This test can show gastrinomas in the pancreas. - Somatostatin receptor scintigraphy. An x-ray technician performs this test, also called OctreoScan, at a hospital or an outpatient center, and a radiologist interprets the images. A person does not need anesthesia. A radioactive compound called a radiotracer, when injected into the bloodstream, selectively labels tumor cells. The labeled cells light up when scanned with a device called a gamma camera. The test can show gastrinomas in the duodenum, pancreas, and other parts of the body. Small gastrinomas may be hard to see; therefore, health care providers may order several types of imaging tests to find gastrinomas. Stomach-acid Measurement Using a sample of stomach juices for analysis, a health care provider may measure the amount of stomach acid a person produces. During the exam, a health care provider puts in a nasogastric tubea tiny tube inserted through the nose and throat that reaches into the stomach. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. Once the tube is placed, a health care provider takes samples of the stomach acid. High acid levels in the stomach indicate Zollinger-Ellison syndrome.

Key Points - There are different types of treatment for patients with small cell lung cancer. - Five types of standard treatment are used: - Surgery - Chemotherapy - Radiation therapy - Laser therapy - Endoscopic stent placement - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for patients with small cell lung cancer. Different types of treatment are available for patients with small cell lung cancer. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Five types of standard treatment are used: Surgery Surgery may be used if the cancer is found in one lung and in nearby lymph nodes only. Because this type of lung cancer is usually found in both lungs, surgery alone is not often used. During surgery, the doctor will also remove lymph nodes to find out if they have cancer in them. Sometimes, surgery may be used to remove a sample of lung tissue to find out the exact type of lung cancer. Even if the doctor removes all the cancer that can be seen at the time of the operation, some patients may be given chemotherapy or radiation therapy after surgery to kill any cancer cells that are left. Treatment given after the surgery, to lower the risk that the cancer will come back, is called adjuvant therapy. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly into the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. See Drugs Approved for Small Cell Lung Cancer for more information. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated. External radiation therapy is used to treat small cell lung cancer, and may also be used as palliative therapy to relieve symptoms and improve quality of life. Radiation therapy to the brain to lessen the risk that cancer will spread to the brain may also be given. Laser therapy Laser therapy is a cancer treatment that uses a laser beam (a narrow beam of intense light) to kill cancer cells. Endoscopic stent placement An endoscope is a thin, tube-like instrument used to look at tissues inside the body. An endoscope has a light and a lens for viewing and may be used to place a stent in a body structure to keep the structure open. An endoscopic stent can be used to open an airway blocked by abnormal tissue. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups. Treatment Options by Stage Limited-Stage Small Cell Lung Cancer Treatment of limited-stage small cell lung cancer may include the following: - Combination chemotherapy and radiation therapy to the chest. Radiation therapy to the brain may later be given to patients with complete responses. - Combination chemotherapy alone for patients who cannot be given radiation therapy. - Surgery followed by chemotherapy. - Surgery followed by chemotherapy and radiation therapy. - Radiation therapy to the brain may be given to patients who have had a complete response, to prevent the spread of cancer to the brain. - Clinical trials of new chemotherapy, surgery, and radiation treatments. Check the list of NCI-supported cancer clinical trials that are now accepting patients with limited stage small cell lung cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug. Talk with your doctor about clinical trials that may be right for you. General information about clinical trials is available from the NCI website. Extensive-Stage Small Cell Lung Cancer Treatment of extensive-stage small cell lung cancer may include the following: - Combination chemotherapy. - Radiation therapy to the brain, spine, bone, or other parts of the body where the cancer has spread, as palliative therapy to relieve symptoms and improve quality of life. - Radiation therapy to the chest may be given to patients who respond to chemotherapy. - Radiation therapy to the brain may be given to patients who have had a complete response, to prevent the spread of cancer to the brain. - Clinical trials of new chemotherapy treatments. Check the list of NCI-supported cancer clinical trials that are now accepting patients with extensive stage small cell lung cancer. For more specific results, refine the search by using other search features, such as the location of the trial, the type of treatment, or the name of the drug.

### Question: What are the treatments for Graves' Disease ? ### Response:

People with Graves disease have three treatment options: radioiodine therapy, medications, and thyroid surgery. Radioiodine therapy is the most common treatment for Graves disease in the United States. Graves disease is often diagnosed and treated by an endocrinologista doctor who specializes in the bodys hormone- secreting glands. Radioiodine Therapy In radioiodine therapy, patients take radioactive iodine-131 by mouth. Because the thyroid gland collects iodine to make thyroid hormone, it will collect the radioactive iodine from the bloodstream in the same way. Iodine-131stronger than the radioactive iodine used in diagnostic testsgradually destroys the cells that make up the thyroid gland but does not affect other body tissues. Many health care providers use a large enough dose of iodine-131 to shut down the thyroid completely, but some prefer smaller doses to try to bring hormone production into the normal range. More than one round of radioiodine therapy may be needed. Results take time and people undergoing this treatment may not notice improvement in symptoms for several weeks or months. People with GO should talk with a health care provider about any risks associated with radioactive iodine treatments. Several studies suggest radioiodine therapy can worsen GO in some people. Other treatments, such as prescription steroids, may prevent this complication. Although iodine-131 is not known to cause birth defects or infertility, radioiodine therapy is not used in pregnant women or women who are breastfeeding. Radioactive iodine can be harmful to the fetus thyroid and can be passed from mother to child in breast milk. Experts recommend that women wait a year after treatment before becoming pregnant. Almost everyone who receives radioactive iodine treatment eventually develops hypothyroidism, which occurs when the thyroid does not make enough thyroid hormone. People with hypothyroidism must take synthetic thyroid hormone, a medication that replaces their natural thyroid hormone. Medications Beta blockers. Health care providers may prescribe a medication called a beta blocker to reduce many of the symptoms of hyperthyroidism, such as tremors, rapid heartbeat, and nervousness. But beta blockers do not stop thyroid hormone production. Anti-thyroid medications. Health care providers sometimes prescribe anti-thyroid medications as the only treatment for Graves disease. Anti-thyroid medications interfere with thyroid hormone production but dont usually have permanent results. Use of these medications requires frequent monitoring by a health care provider. More often, anti-thyroid medications are used to pretreat patients before surgery or radioiodine therapy, or they are used as supplemental treatment after radioiodine therapy. Anti-thyroid medications can cause side effects in some people, including - allergic reactions such as rashes and itching - a decrease in the number of white blood cells in the body, which can lower a persons resistance to infection - liver failure, in rare cases In the United States, health care providers prescribe the anti-thyroid medication methimazole (Tapazole, Northyx) for most types of hyperthyroidism. Anti-thyroid medications and pregnancy. Because pregnant and breastfeeding women cannot receive radioiodine therapy, they are usually treated with an anti-thyroid medication instead. However, experts agree that women in their first trimester of pregnancy should probably not take methimazole due to the rare occurrence of damage to the fetus. Another anti-thyroid medication, propylthiouracil (PTU), is available for women in this stage of pregnancy or for women who are allergic to or intolerant of methimazole and have no other treatment options. Health care providers may prescribe PTU for the first trimester of pregnancy and switch to methimazole for the second and third trimesters. Some women are able to stop taking anti-thyroid medications in the last 4 to 8 weeks of pregnancy due to the remission of hyperthyroidism that occurs during pregnancy. However, these women should continue to be monitored for recurrence of thyroid problems following delivery. Studies have shown that mothers taking anti-thyroid medications may safely breastfeed. However, they should take only moderate doses, less than 1020 milligrams daily, of the anti-thyroid medication methimazole. Doses should be divided and taken after feedings, and the infants should be monitored for side effects.2 Women requiring higher doses of the anti-thyroid medication to control hyperthyroidism should not breastfeed. 2Ogunyemi DA. Autoimmune thyroid disease and pregnancy. emedicine website. emedicine.medscape.com/article/261913-overview. Updated March 12, 2012. Accessed April 10, 2012. Stop your anti-thyroid medication and call your health care provider right away if you develop any of the following while taking anti-thyroid medications: - fatigue - weakness - vague abdominal pain - loss of appetite - skin rash or itching - easy bruising - yellowing of the skin or whites of the eyes, called jaundice - persistent sore throat - fever Thyroid Surgery Surgery is the least-used option for treating Graves disease. Sometimes surgery may be used to treat - pregnant women who cannot tolerate anti-thyroid medications - people suspected of having thyroid cancer, though Graves disease does not cause cancer - people for whom other forms of treatment are not successful Before surgery, the health care provider may prescribe anti-thyroid medications to temporarily bring a patients thyroid hormone levels into the normal range. This presurgical treatment prevents a condition called thyroid storma sudden, severe worsening of symptomsthat can occur when hyperthyroid patients have general anesthesia. When surgery is used, many health care providers recommend the entire thyroid be removed to eliminate the chance that hyperthyroidism will return. If the entire thyroid is removed, lifelong thyroid hormone medication is necessary. Although uncommon, certain problems can occur in thyroid surgery. The parathyroid glands can be damaged because they are located very close to the thyroid. These glands help control calcium and phosphorous levels in the body. Damage to the laryngeal nerve, also located close to the thyroid, can lead to voice changes or breathing problems. But when surgery is performed by an experienced surgeon, less than 1 percent of patients have permanent complications.1 People who need help finding a surgeon can contact one of the organizations listed under For More Information. Eye Care The eye problems associated with Graves disease may not improve following thyroid treatment, so the two problems are often treated separately. Eye drops can relieve dry, gritty, irritated eyesthe most common of the milder symptoms. If pain and swelling occur, health care providers may prescribe a steroid such as prednisone. Other medications that suppress the immune response may also provide relief. Special lenses for glasses can help with light sensitivity and double vision. People with eye symptoms may be advised to sleep with their head elevated to reduce eyelid swelling. If the eyelids do not fully close, taping them shut at night can help prevent dry eyes. In more severe cases, external radiation may be applied to the eyes to reduce inflammation. Like other types of radiation treatment, the benefits are not immediate; most people feel relief from symptoms 1 to 2 months after treatment. Surgery may be used to improve bulging of the eyes and correct the vision changes caused by pressure on the optic nerve. A procedure called orbital decompression makes the eye socket bigger and gives the eye room to sink back to a more normal position. Eyelid surgery can return retracted eyelids to their normal position.

### Question: How to diagnose Arrhythmia ? ### Response:

Arrhythmias can be hard to diagnose, especially the types that only cause symptoms every once in a while. Doctors diagnose arrhythmias based on medical and family histories, a physical exam, and the results from tests and procedures. Specialists Involved Doctors who specialize in the diagnosis and treatment of heart diseases include: Cardiologists. These doctors diagnose and treat adults who have heart problems. Pediatric cardiologists. These doctors diagnose and treat babies, children, and youth who have heart problems. Electrophysiologists. These doctors are cardiologists or pediatric cardiologists who specialize in arrhythmias. Medical and Family Histories To diagnose an arrhythmia, your doctor may ask you to describe your symptoms. He or she may ask whether you feel fluttering in your chest and whether you feel dizzy or light-headed. Your doctor also may ask whether you have other health problems, such as a history of heart disease, high blood pressure, diabetes, or thyroid problems. He or she may ask about your family's medical history, including whether anyone in your family: Has a history of arrhythmias Has ever had heart disease or high blood pressure Has died suddenly Has other illnesses or health problems Your doctor will likely want to know what medicines you're taking, including over-the-counter medicines and supplements. Your doctor may ask about your health habits, such as physical activity, smoking, or using alcohol or drugs (for example, cocaine). He or she also may want to know whether you've had emotional stress or anger. Physical Exam During a physical exam, your doctor may: Listen to the rate and rhythm of your heartbeat Listen to your heart for a heart murmur (an extra or unusual sound heard during your heartbeat) Check your pulse to find out how fast your heart is beating Check for swelling in your legs or feet, which could be a sign of an enlarged heart or heart failure Look for signs of other diseases, such as thyroid disease, that could be causing the problem Diagnostic Tests and Procedures EKG (Electrocardiogram) An EKG is a simple, painless test that detects and records the heart's electrical activity. It's the most common test used to diagnose arrhythmias. An EKG shows how fast the heart is beating and its rhythm (steady or irregular). It also records the strength and timing of electrical signals as they pass through the heart. A standard EKG only records the heartbeat for a few seconds. It won't detect arrhythmias that don't happen during the test. To diagnose arrhythmias that come and go, your doctor may have you wear a portable EKG monitor. The two most common types of portable EKGs are Holter and event monitors. Holter and Event Monitors A Holter monitor records the heart's electrical signals for a full 24- or 48-hour period. You wear one while you do your normal daily activities. This allows the monitor to record your heart for a longer time than a standard EKG. An event monitor is similar to a Holter monitor. You wear an event monitor while doing your normal activities. However, an event monitor only records your heart's electrical activity at certain times while you're wearing it. For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms. Some event monitors are able to send data about your heart's electrical activity to a central monitoring station. Technicians at the station review the information and send it to your doctor. You also can use the device to report any symptoms you're having. You can wear an event monitor for weeks or until symptoms occur. Other Tests Other tests also are used to help diagnose arrhythmias. Blood tests. Blood tests check the level of substances in the blood, such as potassium and thyroid hormone. Abnormal levels of these substances can increase your chances of having an arrhythmia. Chest x ray. A chest x ray is a painless test that creates pictures of the structures in your chest, such as your heart and lungs. This test can show whether your heart is enlarged. Echocardiography. This test uses sound waves to create a moving picture of your heart. Echocardiography (echo) provides information about the size and shape of your heart and how well your heart chambers and valves are working. The test also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow. There are several types of echo, including stress echo. This test is done both before and after a stress test (see below). A stress echo usually is done to find out whether you have decreased blood flow to your heart, a sign of coronary heart disease (CHD). A transesophageal (tranz-ih-sof-uh-JEE-ul) echo, or TEE, is a special type of echo that takes pictures of the heart through the esophagus. The esophagus is the passage leading from your mouth to your stomach. Stress test. Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you can't exercise, you may be given medicine to make your heart work hard and beat fast. The heart tests done during stress testing may include nuclear heart scanning, echo, and positron emission tomography (PET) scanning of the heart. Electrophysiology study (EPS). This test is used to assess serious arrhythmias. During an EPS, a thin, flexible wire is passed through a vein in your groin (upper thigh) or arm to your heart. The wire records your heart's electrical signals. Your doctor can use the wire to electrically stimulate your heart and trigger an arrhythmia. This allows your doctor to see whether an antiarrhythmia medicine can stop the problem. Catheter ablation, a procedure used to treat some arrhythmias, may be done during an EPS. Tilt table testing. This test sometimes is used to help find the cause of fainting spells. You lie on a table that moves from a lying down to an upright position. The change in position may cause you to faint. Your doctor watches your symptoms, heart rate, EKG reading, and blood pressure throughout the test. He or she may give you medicine and then check your response to the medicine. Coronary angiography. Coronary angiography uses dye and special x rays to show the inside of your coronary arteries. To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun). A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream. Special x rays are taken while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels. This helps your doctor find blockages that can cause a heart attack. Implantable loop recorder. This device detects abnormal heart rhythms. Minor surgery is used to place this device under the skin in the chest area. An implantable loop recorder helps doctors figure out why a person may be having palpitations or fainting spells, especially if these symptoms don't happen very often. The device can be used for as long as 12 to 24 months.

### Question: What are the treatments for Atrial Fibrillation ? ### Response:

Treatment for atrial fibrillation (AF) depends on how often you have symptoms, how severe they are, and whether you already have heart disease. General treatment options include medicines, medical procedures, and lifestyle changes. Goals of Treatment The goals of treating AF include: Preventing blood clots from forming, thus lowering the risk of stroke. Controlling how many times a minute the ventricles contract. This is called rate control. Rate control is important because it allows the ventricles enough time to completely fill with blood. With this approach, the abnormal heart rhythm continues, but you feel better and have fewer symptoms. Restoring a normal heart rhythm. This is called rhythm control. Rhythm control allows the atria and ventricles to work together to efficiently pump blood to the body. Treating any underlying disorder that's causing or raising the risk of AFfor example, hyperthyroidism (too much thyroid hormone). Who Needs Treatment for Atrial Fibrillation? People who have AF but don't have symptoms or related heart problems may not need treatment. AF may even go back to a normal heart rhythm on its own. (This also can occur in people who have AF with symptoms.) In some people who have AF for the first time, doctors may choose to use an electrical procedure or medicine to restore a normal heart rhythm. Repeat episodes of AF tend to cause changes to the heart's electrical system, leading to persistent or permanent AF. Most people who have persistent or permanent AF need treatment to control their heart rate and prevent complications. Specific Types of Treatment Blood Clot Prevention People who have AF are at increased risk for stroke. This is because blood can pool in the heart's upper chambers (the atria), causing a blood clot to form. If the clot breaks off and travels to the brain, it can cause a stroke. Preventing blood clots from forming is probably the most important part of treating AF. The benefits of this type of treatment have been proven in multiple studies. Doctors prescribe blood-thinning medicines to prevent blood clots. These medicines include warfarin (Coumadin), dabigatran, heparin, and aspirin. People taking blood-thinning medicines need regular blood tests to check how well the medicines are working. Rate Control Doctors can prescribe medicines to slow down the rate at which the ventricles are beating. These medicines help bring the heart rate to a normal level. Rate control is the recommended treatment for most patients who have AF, even though an abnormal heart rhythm continues and the heart doesn't work as well as it should. Most people feel better and can function well if their heart rates are well-controlled. Medicines used to control the heart rate include beta blockers (for example, metoprolol and atenolol), calcium channel blockers (diltiazem and verapamil), and digitalis (digoxin). Several other medicines also are available. Rhythm Control Restoring and maintaining a normal heart rhythm is a treatment approach recommended for people who aren't doing well with rate control treatment. This treatment also may be used for people who have only recently started having AF. The long-term benefits of rhythm control have not been proven conclusively yet. Doctors use medicines or procedures to control the heart's rhythm. Patients often begin rhythm control treatment in a hospital so that their hearts can be closely watched. The longer you have AF, the less likely it is that doctors can restore a normal heart rhythm. This is especially true for people who have had AF for 6 months or more. Restoring a normal rhythm also becomes less likely if the atria are enlarged or if any underlying heart disease worsens. In these cases, the chance that AF will recur is high, even if you're taking medicine to help convert AF to a normal rhythm. Medicines. Medicines used to control the heart rhythm include amiodarone, sotalol, flecainide, propafenone, dofetilide, and ibutilide. Sometimes older medicinessuch as quinidine, procainamide, and disopyramideare used. Your doctor will carefully tailor the dose and type of medicines he or she prescribes to treat your AF. This is because medicines used to treat AF can cause a different kind of arrhythmia. These medicines also can harm people who have underlying diseases of the heart or other organs. This is especially true for patients who have an unusual heart rhythm problem called Wolff-Parkinson-White syndrome. Your doctor may start you on a small dose of medicine and then gradually increase the dose until your symptoms are controlled. Medicines used for rhythm control can be given regularly by injection at a doctor's office, clinic, or hospital. Or, you may routinely take pills to try to control AF or prevent repeat episodes. If your doctor knows how you'll react to a medicine, a specific dose may be prescribed for you to take on an as-needed basis if you have an episode of AF. Procedures. Doctors use several procedures to restore a normal heart rhythm. For example, they may use electrical cardioversion to treat a fast or irregular heartbeat. For this procedure, low-energy shocks are given to your heart to trigger a normal rhythm. You're temporarily put to sleep before you receive the shocks. Electrical cardioversion isn't the same as the emergency heart shocking procedure often seen on TV programs. It's planned in advance and done under carefully controlled conditions. Before doing electrical cardioversion, your doctor may recommend transesophageal echocardiography (TEE). This test can rule out the presence of blood clots in the atria. If clots are present, you may need to take blood-thinning medicines before the procedure. These medicines can help get rid of the clots. Catheter ablation (ab-LA-shun) may be used to restore a normal heart rhythm if medicines or electrical cardioversion don't work. For this procedure, a wire is inserted through a vein in the leg or arm and threaded to the heart. Radio wave energy is sent through the wire to destroy abnormal tissue that may be disrupting the normal flow of electrical signals. An electrophysiologist usually does this procedure in a hospital. Your doctor may recommend a TEE before catheter ablation to check for blood clots in the atria. Sometimes doctors use catheter ablation to destroy the atrioventricular (AV) node. The AV node is where the heart's electrical signals pass from the atria to the ventricles (the heart's lower chambers). This procedure requires your doctor to surgically implant a device called a pacemaker, which helps maintain a normal heart rhythm. Research on the benefits of catheter ablation as a treatment for AF is still ongoing. (For more information, go to the "Clinical Trials" section of this article.) Another procedure to restore a normal heart rhythm is called maze surgery. For this procedure, the surgeon makes small cuts or burns in the atria. These cuts or burns prevent the spread of disorganized electrical signals. This procedure requires open-heart surgery, so it's usually done when a person requires heart surgery for other reasons, such as for heart valve disease (which can increase the risk of AF). Approaches To Treating Underlying Causes and Reducing Risk Factors Your doctor may recommend treatments for an underlying cause of AF or to reduce AF risk factors. For example, he or she may prescribe medicines to treat an overactive thyroid, lower high blood pressure, or manage high blood cholesterol. Your doctor also may recommend lifestyle changes, such as following a healthy diet, cutting back on salt intake (to help lower blood pressure), quitting smoking, and reducing stress. Limiting or avoiding alcohol, caffeine, or other stimulants that may increase your heart rate also can help reduce your risk for AF.

### Question: How to prevent Prostate Cancer ? ### Response:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following risk factors may increase the risk of prostate cancer: - Age - Family history of prostate cancer - Race - Hormones - Vitamin E - Folic acid - Dairy and calcium - The following protective factors may decrease the risk of prostate cancer: - Folate - Finasteride and Dutasteride - The following have been proven not to affect the risk of prostate cancer, or their effects on prostate cancer risk are not known: - Selenium and vitamin E - Diet - Multivitamins - Lycopene - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent prostate cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. The following risk factors may increase the risk of prostate cancer: Age Prostate cancer is rare in men younger than 50 years of age. The chance of developing prostate cancer increases as men get older. Family history of prostate cancer A man whose father, brother, or son has had prostate cancer has a higher-than-average risk of prostate cancer. Race Prostate cancer occurs more often in African-American men than in white men. African-American men with prostate cancer are more likely to die from the disease than white men with prostate cancer. Hormones The prostate needs male hormones to work the way it should. The main male sex hormone is testosterone. Testosterone helps the body develop and maintain male sex characteristics. Testosterone is changed into dihydrotestosterone (DHT) by an enzyme in the body. DHT is important for normal prostate growth but can also cause the prostate to get bigger and may play a part in the development of prostate cancer. Vitamin E The Selenium and Vitamin E Cancer Prevention Trial (SELECT) found that vitamin E taken alone increased the risk of prostate cancer. The risk continued even after the men stopped taking vitamin E. Folic acid Folate is a kind of vitamin B that occurs naturally in some foods, such as green vegetables, beans and orange juice. Folic acid is a man-made form of folate that is found in vitamin supplements and fortified foods, such as whole-grain breads and cereals. A 10-year study showed that the risk of prostate cancer was increased in men who took 1 milligram (mg) supplements of folic acid. However, the risk of prostate cancer was lower in men who had enough folate in their diets. Dairy and calcium A diet high in dairy foods and calcium may cause a small increase in the risk of prostate cancer. The following protective factors may decrease the risk of prostate cancer: Folate Folate is a kind of vitamin B that occurs naturally in some foods, such as green vegetables, beans and orange juice. Folic acid is a man-made form of folate that is found in vitamin supplements and fortified foods, such as whole-grain breads and cereals. A 10-year study showed that the risk of prostate cancer was lower in men who had enough folate in their diets. However, the risk of prostate cancer was increased in men who took 1 milligram (mg) supplements of folic acid. Finasteride and Dutasteride Finasteride and dutasteride are drugs used to lower the amount of male sex hormones made by the body. These drugs block the enzyme that changes testosterone into dihydrotestosterone (DHT). Higher than normal levels of DHT may play a part in developing prostate cancer. Taking finasteride or dutasteride has been shown to lower the risk for prostate cancer, but it is not known if these drugs lower the risk of death from prostate cancer. The Prostate Cancer Prevention Trial (PCPT) studied whether the drug finasteride can prevent prostate cancer in healthy men 55 years of age and older. This prevention study showed there were fewer prostate cancers in the group of men that took finasteride compared with the group of men that did not. Also, the men who took finasteride who did have prostate cancer had more aggressive tumors. The number of deaths from prostate cancer was the same in both groups. Men who took finasteride reported more side effects compared with the group of men that did not, including erectile dysfunction, loss of desire for sex, and enlarged breasts. The Reduction by Dutasteride of Prostate Cancer Events Trial (REDUCE) studied whether the drug dutasteride can prevent prostate cancer in men aged 50 to 75 years at higher risk for the disease. This prevention study showed there were fewer prostate cancers in the group of men who took dutasteride compared with the group of men that did not. The number of less aggressive prostate cancers was lower, but the number of more aggressive prostate cancers was not. Men who took dutasteride reported more side effects than men who did not, including erectile dysfunction, loss of desire for sex, less semen, and gynecomastia (enlarged breasts). The following have been proven not to affect the risk of prostate cancer, or their effects on prostate cancer risk are not known: Selenium and vitamin E The Selenium and Vitamin E Cancer Prevention Trial (SELECT) studied whether taking vitamin E and selenium (a mineral) will prevent prostate cancer. The selenium and vitamin E were taken separately or together by healthy men 55 years of age and older (50 years of age and older for African-American men). The study showed that taking selenium alone or selenium and vitamin E together did not decrease the risk of prostate cancer. Diet It is not known if decreasing fat or increasing fruits and vegetables in the diet helps decrease the risk of prostate cancer or death from prostate cancer. In the PCPT trial, certain fatty acids increased the risk of high-grade prostate cancer while others decreased the risk of high-grade prostate cancer. Multivitamins Regular use of multivitamins has not been proven to increase the risk of early or localized prostate cancer. However, a large study showed an increased risk of advanced prostate cancer among men who took multivitamins more than seven times a week. Lycopene Some studies have shown that a diet high in lycopene may be linked to a decreased risk of prostate cancer, but other studies have not. It has not been proven that taking lycopene supplements decreases the risk of prostate cancer. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent prostate cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country.

### Question: What are the stages of Uterine Sarcoma ? ### Response:

Key Points - After uterine sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. - Uterine sarcoma may be diagnosed, staged, and treated in the same surgery. - 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 uterine sarcoma: - Stage I - Stage II - Stage III - Stage IV After uterine sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. The process used to find out if cancer has spread within the uterus 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 following procedures may be used in the staging process: - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - CA 125 assay : A test that measures the level of CA 125 in the blood. CA 125 is a substance released by cells into the bloodstream. An increased CA 125 level is sometimes a sign of cancer or other condition. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Transvaginal ultrasound exam: A procedure used to examine the vagina, uterus, fallopian tubes, and bladder. An ultrasound transducer (probe) is inserted into the vagina and used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The doctor can identify tumors by looking at the sonogram. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the abdomen and pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues to show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - Cystoscopy : A procedure to look inside the bladder and urethra to check for abnormal areas. A cystoscope is inserted through the urethra into the bladder. A cystoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer. Uterine sarcoma may be diagnosed, staged, and treated in the same surgery. Surgery is used to diagnose, stage, and treat uterine sarcoma. During this surgery, the doctor removes as much of the cancer as possible. The following procedures may be used to diagnose, stage, and treat uterine sarcoma: - Laparotomy: A surgical procedure in which an incision (cut) is made in the wall of the abdomen to check the inside of the abdomen for signs of disease. The size of the incision depends on the reason the laparotomy is being done. Sometimes organs are removed or tissue samples are taken and checked under a microscope for signs of disease. - Abdominal and pelvic washings: A procedure in which a saline solution is placed into the abdominal and pelvic body cavities. After a short time, the fluid is removed and viewed under a microscope to check for cancer cells. - Total abdominal hysterectomy: A surgical procedure to remove the uterus and cervix through a large incision (cut) in the abdomen. - Bilateral salpingo-oophorectomy: Surgery to remove both ovaries and both fallopian tubes. - Lymphadenectomy: A surgical procedure in which lymph nodes are removed and checked under a microscope for signs of cancer. For a regional lymphadenectomy, some of the lymph nodes in the tumor area are removed. For a radical lymphadenectomy, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymph node dissection. Treatment in addition to surgery may be given, as described in the Treatment Option Overview section of this summary. 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 uterine sarcoma spreads to the lung, the cancer cells in the lung are actually uterine sarcoma cells. The disease is metastatic uterine sarcoma, not lung cancer. The following stages are used for uterine sarcoma: Stage I In stage I, cancer is found in the uterus only. Stage I is divided into stages IA and IB, based on how far the cancer has spread. - Stage IA: Cancer is in the endometrium only or less than halfway through the myometrium (muscle layer of the uterus). - Stage IB: Cancer has spread halfway or more into the myometrium. Stage II In stage II, cancer has spread into connective tissue of the cervix, but has not spread outside the uterus. Stage III In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis. - Stage IIIA: Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, and ligaments of the uterus. - Stage IIIB: Cancer has spread to the vagina or to the parametrium (connective tissue and fat around the uterus). - Stage IIIC: Cancer has spread to lymph nodes in the pelvis and/or around the aorta (largest artery in the body, which carries blood away from the heart). Stage IV In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread. - Stage IVA: Cancer has spread to the bladder and/or bowel wall. - Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including the abdomen and/or lymph nodes in the groin.

### Question: What are the stages of Laryngeal Cancer ? ### Response:

Key Points - After laryngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the larynx 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 laryngeal cancer: - Stage 0 (Carcinoma in Situ) - Stage I - Stage II - Stage III - Stage IV After laryngeal cancer has been diagnosed, tests are done to find out if cancer cells have spread within the larynx or to other parts of the body. The process used to find out if cancer has spread within the larynx 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 of the disease in order to plan treatment. The results of some of the tests used to diagnose laryngeal cancer are often also used to stage the disease. 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 laryngeal cancer spreads to the lung, the cancer cells in the lung are actually laryngeal cancer cells. The disease is metastatic laryngeal cancer, not lung cancer. The following stages are used for laryngeal cancer: Stage 0 (Carcinoma in Situ) In stage 0, abnormal cells are found in the lining of the larynx. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. Stage I In stage I, cancer has formed. Stage I laryngeal cancer depends on where cancer began in the larynx: - Supraglottis: Cancer is in one area of the supraglottis only and the vocal cords can move normally. - Glottis: Cancer is in one or both vocal cords and the vocal cords can move normally. - Subglottis: Cancer is in the subglottis only. Stage II In stage II, cancer is in the larynx only. Stage II laryngeal cancer depends on where cancer began in the larynx: - Supraglottis: Cancer is in more than one area of the supraglottis or surrounding tissues. - Glottis: Cancer has spread to the supraglottis and/or the subglottis and/or the vocal cords cannot move normally. - Subglottis: Cancer has spread to one or both vocal cords, which may not move normally. Stage III Stage III laryngeal cancer depends on whether cancer has spread from the supraglottis, glottis, or subglottis. In stage III cancer of the supraglottis: - cancer is in the larynx only and the vocal cords cannot move, and/or cancer is in tissues next to the larynx. Cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in one area of the supraglottis and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller and the vocal cords can move normally; or - cancer is in more than one area of the supraglottis or surrounding tissues and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller. In stage III cancer of the glottis: - cancer is in the larynx only and the vocal cords cannot move, and/or cancer is in tissues next to the larynx; cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in one or both vocal cords and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller and the vocal cords can move normally; or - cancer has spread to the supraglottis and/or the subglottis and/or the vocal cords cannot move normally. Cancer has also spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller. In stage III cancer of the subglottis: - cancer is in the larynx and the vocal cords cannot move; cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer is in the subglottis and in one lymph node on the same side of the neck as the original tumor; the lymph node is 3 centimeters or smaller; or - cancer has spread to one or both vocal cords, which may not move normally. Cancer has also spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller. Stage IV Stage IV is divided into stage IVA, stage IVB, and stage IVC. Each substage is the same for cancer in the supraglottis, glottis, or subglottis. - In stage IVA: - cancer has spread through the thyroid cartilage and/or has spread to tissues beyond the larynx such as the neck, trachea, thyroid, or esophagus. Cancer may have spread to one lymph node on the same side of the neck as the original tumor and the lymph node is 3 centimeters or smaller; or - cancer has spread to one lymph node on the same side of the neck as the original tumor and the lymph node is larger than 3 centimeters but not larger than 6 centimeters, or has spread to more than one lymph node anywhere in the neck with none larger than 6 centimeters. Cancer may have spread to tissues beyond the larynx, such as the neck, trachea, thyroid, or esophagus. The vocal cords may not move normally. - In stage IVB: - cancer has spread to the space in front of the spinal column, surrounds the carotid artery, or has spread to parts of the chest. Cancer may have spread to one or more lymph nodes anywhere in the neck and the lymph nodes may be any size; or - cancer has spread to a lymph node that is larger than 6 centimeters and may have spread as far as the space in front of the spinal column, around the carotid artery, or to parts of the chest. The vocal cords may not move normally. - In stage IVC, cancer has spread to other parts of the body, such as the lungs, liver, or bone.

### Question: What are the stages of Melanoma ? ### Response:

Key Points - After melanoma has been diagnosed, tests are done to find out if cancer cells have spread within the skin 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 method used to stage melanoma is based mainly on the thickness of the tumor and whether cancer has spread to lymph nodes or other parts of the body. - The following stages are used for melanoma: - Stage 0 (Melanoma in Situ) - Stage I - Stage II - Stage III - Stage IV After melanoma has been diagnosed, tests are done to find out if cancer cells have spread within the skin or to other parts of the body. The process used to find out whether cancer has spread within the skin 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 following tests and procedures may be used in the staging process: - 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. - Lymph node mapping and sentinel lymph node biopsy : Procedures in which a radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through lymph ducts to the sentinel node or nodes (the first lymph node or nodes where cancer cells are likely to spread). The surgeon removes only the nodes with the radioactive substance or dye. A pathologist views a sample of tissue under a microscope to check for cancer cells. If no cancer cells are found, it may not be necessary to remove more nodes. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. For melanoma, pictures may be taken of the chest, abdomen, and pelvis. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body, such as the brain. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. For melanoma, the blood is checked for an enzyme called lactate dehydrogenase (LDH). LDH levels that are higher than normal may be a sign of melanoma. The results of these tests are viewed together with the results of the tumor biopsy to find out the stage of the melanoma. 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 melanoma spreads to the lung, the cancer cells in the lung are actually melanoma cells. The disease is metastatic melanoma, not lung cancer. The method used to stage melanoma is based mainly on the thickness of the tumor and whether cancer has spread to lymph nodes or other parts of the body. The staging of melanoma depends on the following: - The thickness of the tumor. The thickness is described using the Breslow scale. - Whether the tumor is ulcerated (has broken through the skin). - Whether the tumor has spread to the lymph nodes and if the lymph nodes are joined together (matted). - Whether the tumor has spread to other parts of the body. The following stages are used for melanoma: Stage 0 (Melanoma in Situ) In stage 0, abnormal melanocytes are found in the epidermis. These abnormal melanocytes may become cancer and spread into nearby normal tissue. Stage 0 is also called melanoma in situ. Stage I In stage I, cancer has formed. Stage I is divided into stages IA and IB. - Stage IA: In stage IA, the tumor is not more than 1 millimeter thick, with no ulceration. - Stage IB: In stage IB, the tumor is either: - not more than 1 millimeter thick and it has ulceration; or - more than 1 but not more than 2 millimeters thick, with no ulceration. Stage II Stage II is divided into stages IIA, IIB, and IIC. - Stage IIA: In stage IIA, the tumor is either: - more than 1 but not more than 2 millimeters thick, with ulceration; or - more than 2 but not more than 4 millimeters thick, with no ulceration. - Stage IIB: In stage IIB, the tumor is either: - more than 2 but not more than 4 millimeters thick, with ulceration; or - more than 4 millimeters thick, with no ulceration. - Stage IIC: In stage IIC, the tumor is more than 4 millimeters thick, with ulceration. Stage III In stage III, the tumor may be any thickness, with or without ulceration. One or more of the following is true: - Cancer has spread to one or more lymph nodes. - Lymph nodes are joined together (matted). - Cancer is in a lymph vessel between the primary tumor and nearby lymph nodes. The cancer is more than 2 centimeters away from the primary tumor. - Very small tumors are found on or under the skin, not more than 2 centimeters away from the primary tumor. Stage IV In stage IV, the cancer has spread to other places in the body, such as the lung, liver, brain, bone, soft tissue, or gastrointestinal (GI) tract. Cancer may have spread to places in the skin far away from where it first started.

### Question: What are the treatments for Diabetic Neuropathies: The Nerve Damage of Diabetes ? ### Response:

The first treatment step is to bring blood glucose levels within the normal range to help prevent further nerve damage. Blood glucose monitoring, meal planning, physical activity, and diabetes medicines or insulin will help control blood glucose levels. Symptoms may get worse when blood glucose is first brought under control, but over time, maintaining lower blood glucose levels helps lessen symptoms. Good blood glucose control may also help prevent or delay the onset of further problems. As scientists learn more about the underlying causes of neuropathy, new treatments may become available to help slow, prevent, or even reverse nerve damage. As described in the following sections, additional treatment depends on the type of nerve problem and symptom. Pain Relief Doctors usually treat painful diabetic neuropathy with oral medications, although other types of treatments may help some people. People with severe nerve pain may benefit from a combination of medications or treatments and should consider talking with a health care provider about treatment options. Medications used to help relieve diabetic nerve pain include - tricyclic antidepressants, such as amitriptyline, imipramine, and desipramine (Norpramin, Pertofrane) - other types of antidepressants, such as duloxetine (Cymbalta), venlafaxine, bupropion (Wellbutrin), paroxetine (Paxil), and citalopram (Celexa) - anticonvulsants, such as pregabalin (Lyrica), gabapentin (Gabarone, Neurontin), carbamazepine, and lamotrigine (Lamictal) - opioids and opioidlike drugs, such as controlled-release oxycodone, an opioid; and tramadol (Ultram), an opioid that also acts as an antidepressant Duloxetine and pregabalin are approved by the U.S. Food and Drug Administration specifically for treating painful diabetic peripheral neuropathy. People do not have to be depressed for an antidepressant to help relieve their nerve pain. All medications have side effects, and some are not recommended for use in older adults or those with heart disease. Because over-the-counter pain medicines such as acetaminophen and ibuprofen may not work well for treating most nerve pain and can have serious side effects, some experts recommend avoiding these medications. Treatments that are applied to the skintypically to the feetinclude capsaicin cream and lidocaine patches (Lidoderm, Lidopain). Studies suggest that nitrate sprays or patches for the feet may relieve pain. Studies of alpha-lipoic acid, an antioxidant, and evening primrose oil suggest they may help relieve symptoms and improve nerve function in some patients. A device called a bed cradle can keep sheets and blankets from touching sensitive feet and legs. Acupuncture, biofeedback, or physical therapy may help relieve pain in some people. Treatments that involve electrical nerve stimulation, magnetic therapy, and laser or light therapy may be helpful but need further study. Researchers are also studying several new therapies in clinical trials. Gastrointestinal Problems To relieve mild symptoms of gastroparesisindigestion, belching, nausea, or vomitingdoctors suggest eating small, frequent meals; avoiding fats; and eating less fiber. When symptoms are severe, doctors may prescribe erythromycin to speed digestion, metoclopramide to speed digestion and help relieve nausea, or other medications to help regulate digestion or reduce stomach acid secretion. To relieve diarrhea or other bowel problems, doctors may prescribe an antibiotic such as tetracycline, or other medications as appropriate. Dizziness and Weakness Sitting or standing slowly may help prevent the light-headedness, dizziness, or fainting associated with blood pressure and circulation problems. Raising the head of the bed or wearing elastic stockings may also help. Some people benefit from increased salt in the diet and treatment with salt-retaining hormones. Others benefit from high blood pressure medications. Physical therapy can help when muscle weakness or loss of coordination is a problem. Urinary and Sexual Problems To clear up a urinary tract infection, the doctor will probably prescribe an antibiotic. Drinking plenty of fluids will help prevent another infection. People who have incontinence should try to urinate at regular intervalsevery 3 hours, for examplebecause they may not be able to tell when the bladder is full. To treat erectile dysfunction in men, the doctor will first do tests to rule out a hormonal cause. Several methods are available to treat erectile dysfunction caused by neuropathy. Medicines are available to help men have and maintain erections by increasing blood flow to the penis. Some are oral medications and others are injected into the penis or inserted into the urethra at the tip of the penis. Mechanical vacuum devices can also increase blood flow to the penis. Another option is to surgically implant an inflatable or semirigid device in the penis. Vaginal lubricants may be useful for women when neuropathy causes vaginal dryness. To treat problems with arousal and orgasm, the doctor may refer women to a gynecologist. Foot Care People with neuropathy need to take special care of their feet. The nerves to the feet are the longest in the body and are the ones most often affected by neuropathy. Loss of sensation in the feet means that sores or injuries may not be noticed and may become ulcerated or infected. Circulation problems also increase the risk of foot ulcers. Smoking increases the risk of foot problems and amputation. A health care provider may be able to provide help with quitting smoking. More than 60 percent of all nontraumatic lower-limb amputations in the United States occur in people with diabetes. Nontraumatic amputations are those not caused by trauma such as severe injuries from an accident. In 2004, about 71,000 nontraumatic amputations were performed in people with diabetes. Comprehensive foot care programs can reduce amputation rates by 45 to 85 percent. Careful foot care involves - cleaning the feet daily using warmnot hotwater and a mild soap. Soaking the feet should be avoided. A soft towel can be used to dry the feet and between the toes. - inspecting the feet and toes every day for cuts, blisters, redness, swelling, calluses, or other problems. Using a mirrorhandheld or placed on the floormay be helpful in checking the bottoms of the feet, or another person can help check the feet. A health care provider should be notified of any problems. - using lotion to moisturize the feet. Getting lotion between the toes should be avoided. - filing corns and calluses gently with a pumice stone after a bath or shower. - cutting toenails to the shape of the toes and filing the edges with an emery board each week or when needed. - always wearing shoes or slippers to protect feet from injuries. Wearing thick, soft, seamless socks can prevent skin irritation. - wearing shoes that fit well and allow the toes to move. New shoes can be broken in gradually by first wearing them for only an hour at a time. - looking shoes over carefully before putting them on and feeling the insides to make sure the shoes are free of tears, sharp edges, or objects that might injure the feet. People who need help taking care of their feet should consider making an appointment to see a foot doctor, also called a podiatrist.

### Question: What are the treatments for Hypoglycemia ? ### Response:

Signs and symptoms of hypoglycemia vary from person to person. People with diabetes should get to know their signs and symptoms and describe them to their friends and family so they can help if needed. School staff should be told how to recognize a child's signs and symptoms of hypoglycemia and how to treat it. People who experience hypoglycemia several times in a week should call their health care provider. They may need a change in their treatment plan: less medication or a different medication, a new schedule for insulin or medication, a different meal plan, or a new physical activity plan. Prompt Treatment for Hypoglycemia When people think their blood glucose is too low, they should check the blood glucose level of a blood sample using a meter. If the level is below 70 mg/dL, one of these quick-fix foods should be consumed right away to raise blood glucose: - 3 or 4 glucose tablets - 1 serving of glucose gelthe amount equal to 15 grams of carbohydrate - 1/2 cup, or 4 ounces, of any fruit juice - 1/2 cup, or 4 ounces, of a regularnot dietsoft drink - 1 cup, or 8 ounces, of milk - 5 or 6 pieces of hard candy - 1 tablespoon of sugar or honey Recommended amounts may be less for small children. The child's doctor can advise about the right amount to give a child. The next step is to recheck blood glucose in 15 minutes to make sure it is 70 mg/dL or above. If it's still too low, another serving of a quick-fix food should be eaten. These steps should be repeated until the blood glucose level is 70 mg/dL or above. If the next meal is an hour or more away, a snack should be eaten once the quick-fix foods have raised the blood glucose level to 70 mg/dL or above. For People Who Take Acarbose (Precose) or Miglitol (Glyset) People who take either of these diabetes medications should know that only pure glucose, also called dextroseavailable in tablet or gel formwill raise their blood glucose level during a low blood glucose episode. Other quick-fix foods and drinks won't raise the level quickly enough because acarbose and miglitol slow the digestion of other forms of carbohydrate. Help from Others for Severe Hypoglycemia Severe hypoglycemiavery low blood glucosecan cause a person to pass out and can even be life threatening. Severe hypoglycemia is more likely to occur in people with type 1 diabetes. People should ask a health care provider what to do about severe hypoglycemia. Another person can help someone who has passed out by giving an injection of glucagon. Glucagon will rapidly bring the blood glucose level back to normal and help the person regain consciousness. A health care provider can prescribe a glucagon emergency kit. Family, friends, or coworkersthe people who will be around the person at risk of hypoglycemiacan learn how to give a glucagon injection and when to call 911 or get medical help. Physical Activity and Blood Glucose Levels Physical activity has many benefits for people with diabetes, including lowering blood glucose levels. However, physical activity can make levels too low and can cause hypoglycemia up to 24 hours afterward. A health care provider can advise about checking the blood glucose level before exercise. For those who take insulin or one of the oral medications that increase insulin production, the health care provider may suggest having a snack if the glucose level is below 100 mg/dL or adjusting medication doses before physical activity to help avoid hypoglycemia. A snack can prevent hypoglycemia. The health care provider may suggest extra blood glucose checks, especially after strenuous exercise. Hypoglycemia When Driving Hypoglycemia is particularly dangerous if it happens to someone who is driving. People with hypoglycemia may have trouble concentrating or seeing clearly behind the wheel and may not be able to react quickly to road hazards or to the actions of other drivers. To prevent problems, people at risk for hypoglycemia should check their blood glucose level before driving. During longer trips, they should check their blood glucose level frequently and eat snacks as needed to keep the level at 70 mg/dL or above. If necessary, they should stop for treatment and then make sure their blood glucose level is 70 mg/dL or above before starting to drive again. Hypoglycemia Unawareness Some people with diabetes do not have early warning signs of low blood glucose, a condition called hypoglycemia unawareness. This condition occurs most often in people with type 1 diabetes, but it can also occur in people with type 2 diabetes. People with hypoglycemia unawareness may need to check their blood glucose level more often so they know when hypoglycemia is about to occur. They also may need a change in their medications, meal plan, or physical activity routine. Hypoglycemia unawareness develops when frequent episodes of hypoglycemia lead to changes in how the body reacts to low blood glucose levels. The body stops releasing the hormone epinephrine and other stress hormones when blood glucose drops too low. The loss of the body's ability to release stress hormones after repeated episodes of hypoglycemia is called hypoglycemia-associated autonomic failure, or HAAF. Epinephrine causes early warning symptoms of hypoglycemia such as shakiness, sweating, anxiety, and hunger. Without the release of epinephrine and the symptoms it causes, a person may not realize that hypoglycemia is occurring and may not take action to treat it. A vicious cycle can occur in which frequent hypoglycemia leads to hypoglycemia unawareness and HAAF, which in turn leads to even more severe and dangerous hypoglycemia. Studies have shown that preventing hypoglycemia for a period as short as several weeks can sometimes break this cycle and restore awareness of symptoms. Health care providers may therefore advise people who have had severe hypoglycemia to aim for higher-than-usual blood glucose targets for short-term periods. Being Prepared for Hypoglycemia People who use insulin or take an oral diabetes medication that can cause low blood glucose should always be prepared to prevent and treat low blood glucose by - learning what can trigger low blood glucose levels - having their blood glucose meter available to test glucose levels; frequent testing may be critical for those with hypoglycemia unawareness, particularly before driving a car or engaging in any hazardous activity - always having several servings of quick-fix foods or drinks handy - wearing a medical identification bracelet or necklace - planning what to do if they develop severe hypoglycemia - telling their family, friends, and coworkers about the symptoms of hypoglycemia and how they can help if needed Normal and Target Blood Glucose Ranges Normal Blood Glucose Levels in People Who Do Not Have Diabetes Upon wakingfasting 70 to 99 mg/dL After meals 70 to 140 mg/dL Target Blood Glucose Levels in People Who Have Diabetes Before meals 70 to 130 mg/dL 1 to 2 hours after the start of a meal below 180 mg/dL For people with diabetes, a blood glucose level below 70 mg/dL is considered hypoglycemia.

### Question: How to prevent Skin Cancer ? ### Response:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - Being exposed to ultraviolet radiation is a risk factor for skin cancer. - It is not known if the following lower the risk of nonmelanoma skin cancer: - Sunscreen use and avoiding sun exposure - Chemopreventive agents - It is not known if the following lower the risk of melanoma: - Sunscreen - Counseling and protecting the skin from the sun - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent skin cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. Being exposed to ultraviolet radiation is a risk factor for skin cancer. Some studies suggest that being exposed to ultraviolet (UV) radiation and the sensitivity of a persons skin to UV radiation are risk factors for skin cancer. UV radiation is the name for the invisible rays that are part of the energy that comes from the sun. Sunlamps and tanning beds also give off UV radiation. Risk factors for nonmelanoma and melanoma cancers are not the same. - Risk factors for nonmelanoma skin cancer: - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Having actinic keratosis. - Past treatment with radiation. - Having a weakened immune system. - Being exposed to arsenic. - Risk factors for melanoma skin cancer: - Having a fair complexion, which includes the following: - Fair skin that freckles and burns easily, does not tan, or tans poorly. - Blue or green or other light-colored eyes. - Red or blond hair. - Being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. - Having a history of many blistering sunburns, especially as a child or teenager. - Having several large or many small moles. - Having a family history of unusual moles (atypical nevus syndrome). - Having a family or personal history of melanoma. - Being white. It is not known if the following lower the risk of nonmelanoma skin cancer: Sunscreen use and avoiding sun exposure It is not known if nonmelanoma skin cancer risk is decreased by staying out of the sun, using sunscreens, or wearing protective clothing when outdoors. This is because not enough studies have been done to prove this. Sunscreen may help decrease the amount of UV radiation to the skin. One study found that wearing sunscreen can help prevent actinic keratoses, scaly patches of skin that sometimes become squamous cell carcinoma. The harms of using sunscreen are likely to be small and include allergic reactions to skin creams and lower levels of vitamin D made in the skin because of less sun exposure. It is also possible that when a person uses sunscreen to avoid sunburn they may spend too much time in the sun and be exposed to harmful UV radiation. Although protecting the skin and eyes from the sun has not been proven to lower the chance of getting skin cancer, skin experts suggest the following: - Use sunscreen that protects against UV radiation. - Do not stay out in the sun for long periods of time, especially when the sun is at its strongest. - Wear long sleeve shirts, long pants, sun hats, and sunglasses, when outdoors. Chemopreventive agents Chemoprevention is the use of drugs, vitamins, or other agents to try to reduce the risk of cancer. The following chemopreventive agents have been studied to find whether they lower the risk of nonmelanoma skin cancer: Beta carotene Studies of beta carotene (taken as a supplement in pills) have not shown that it prevents nonmelanoma skin cancer from forming or coming back. Isotretinoin High doses of isotretinoin have been shown to prevent new skin cancers in patients with xeroderma pigmentosum. However, isotretinoin has not been shown to prevent nonmelanoma skin cancers from coming back in patients previously treated for nonmelanoma skin cancers. Treatment with isotretinoin can cause serious side effects. Selenium Studies have shown that selenium (taken in brewer's yeast tablets) does not lower the risk of basal cell carcinoma, and may increase the risk of squamous cell carcinoma. Celecoxib A study of celecoxib in patients with actinic keratosis and a history of nonmelanoma skin cancer found those who took celecoxib had slightly lower rates of recurrent nonmelanoma skin cancers. Celecoxib may have serious side effects on the heart and blood vessels. Alpha-difluoromethylornithine (DFMO) A study of alpha-difluoromethylornithine (DFMO) in patients with a history of nonmelanoma skin cancer showed that those who took DFMO had lower rates of nonmelanoma skin cancers coming back than those who took a placebo. DFMO may cause hearing loss which is usually temporary. Nicotinamide (vitamin B3) Studies have shown that nicotinamide (vitamin B3) helps prevent new actinic keratoses lesions from forming in people who had four or fewer actinic lesions before taking nicotinamide. More studies are needed to find out if nicotinamide prevents nonmelanoma skin cancer from forming or coming back. It is not known if the following lower the risk of melanoma: Sunscreen It has not been proven that using sunscreen to prevent sunburn can protect against melanoma caused by UV radiation. Other risk factors such as having skin that burns easily, having a large number of benign moles, or having atypical nevi may also play a role in whether melanoma forms. Counseling and protecting the skin from the sun It is not known if people who receive counseling or information about avoiding sun exposure make changes in their behavior to protect their skin from the sun. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of developing certain types of cancer. Some cancer prevention trials are conducted with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are conducted with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent skin cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI Web site. Check NCI's list of cancer clinical trials for nonmelanoma skin cancer prevention trials and melanoma prevention trials that are now accepting patients.

### Question: What to do for Fecal Incontinence ? ### Response:

Dietary changes that may improve fecal incontinence include - Eating the right amount of fiber. Fiber can help with diarrhea and constipation. Fiber is found in fruits, vegetables, whole grains, and beans. Fiber supplements sold in a pharmacy or in a health food store are another common source of fiber to treat fecal incontinence. The Academy of Nutrition and Dietetics recommends consuming 20 to 35 grams of fiber a day for adults and age plus five grams for children. A 7-year-old child, for example, should get 7 plus five, or 12, grams of fiber a day. American adults consume only 15 grams a day on average.2 Fiber should be added to the diet slowly to avoid bloating. - Getting plenty to drink. Drinking eight 8-ounce glasses of liquid a day may help prevent constipation. Water is a good choice. Drinks with caffeine, alcohol, milk, or carbonation should be avoided if they trigger diarrhea. Keeping a Food Diary A food diary can help identify foods that cause diarrhea and increase the risk of fecal incontinence. A food diary should list foods eaten, portion size, and when fecal incontinence occurs. After a few days, the diary may show a link between certain foods and fecal incontinence. Eating less of foods linked to fecal incontinence may improve symptoms. A food diary can also be helpful to a health care provider treating a person with fecal incontinence. Common foods and drinks linked to fecal incontinence include - dairy products such as milk, cheese, and ice cream - drinks and foods containing caffeine - cured or smoked meat such as sausage, ham, and turkey - spicy foods - alcoholic beverages - fruits such as apples, peaches, and pears - fatty and greasy foods - sweeteners in diet drinks and sugarless gum and candy, including sorbitol, xylitol, mannitol, and fructose Examples of Foods That Have Fiber Beans, cereals, and breads Fiber cup of beans (navy, pinto, kidney, etc.), cooked 6.29.6 grams cup of shredded wheat, ready-to-eat cereal 2.73.8 grams cup of 100% bran, ready-to-eat cereal 9.1 grams 1 small oat bran muffin 3.0 grams 1 whole-wheat English muffin 4.4 grams Fruits 1 small apple, with skin 3.6 grams 1 medium pear, with skin 5.5 grams cup of raspberries 4.0 grams cup of stewed prunes 3.8 grams Vegetables cup of winter squash, cooked 2.9 grams 1 medium sweet potato, baked in skin 3.8 grams cup of green peas, cooked 3.54.4 grams 1 small potato, baked, with skin 3.0 grams cup of mixed vegetables, cooked 4.0 grams cup of broccoli, cooked 2.62.8 grams cup of greens (spinach, collards, turnip greens), cooked 2.53.5 grams Medications If diarrhea is causing fecal incontinence, medication may help. Health care providers sometimes recommend using bulk laxatives, such as Citrucel and Metamucil, to develop more solid stools that are easier to control. Antidiarrheal medications such as loperamide or diphenoxylate may be recommended to slow down the bowels and help control the problem. Bowel Training Developing a regular bowel movement pattern can improve fecal incontinence, especially fecal incontinence due to constipation. Bowel training involves trying to have bowel movements at specific times of the day, such as after every meal. Over time, the body becomes used to a regular bowel movement pattern, thus reducing constipation and related fecal incontinence. Persistence is key to successful bowel training. Achieving a regular bowel control pattern can take weeks to months. Pelvic Floor Exercises and Biofeedback Exercises that strengthen the pelvic floor muscles may improve bowel control. Pelvic floor exercises involve squeezing and relaxing pelvic floor muscles 50 to 100 times a day. A health care provider can help with proper technique. Biofeedback therapy may also help a person perform the exercises properly. This therapy also improves a persons awareness of sensations in the rectum, teaching how to coordinate squeezing of the external sphincter muscle with the sensation of rectal filling. Biofeedback training uses special sensors to measure bodily functions. Sensors include pressure or EMG sensors in the anus, pressure sensors in the rectum, and a balloon in the rectum to produce graded sensations of rectal fullness. The measurements are displayed on a video screen as sounds or line graphs. The health care provider uses the information to help the person modify or change abnormal function. The person practices the exercises at home. Success with pelvic floor exercises depends on the cause of fecal incontinence, its severity, and the persons motivation and ability to follow the health care providers recommendations. Surgery Surgery may be an option for fecal incontinence that fails to improve with other treatments or for fecal incontinence caused by pelvic floor or anal sphincter muscle injuries. - Sphincteroplasty, the most common fecal incontinence surgery, reconnects the separated ends of a sphincter muscle torn by childbirth or another injury. Sphincteroplasty is performed at a hospital by a colorectal, gynecological, or general surgeon. - Artificial anal sphincter involves placing an inflatable cuff around the anus and implanting a small pump beneath the skin that the person activates to inflate or deflate the cuff. This surgery is much less common and is performed at a hospital by a specially trained colorectal surgeon. - Nonabsorbable bulking agents can be injected into the wall of the anus to bulk up the tissue around the anus. The bulkier tissues make the opening of the anus narrower so the sphincters are able to close better. The procedure is performed in a health care providers office; anesthesia is not needed. The person can return to normal physical activities 1 week after the procedure. - Bowel diversion is an operation that reroutes the normal movement of stool out of the body when part of the bowel is removed. The operation diverts the lower part of the small intestine or colon to an opening in the wall of the abdomenthe area between the chest and hips. An external pouch is attached to the opening to collect stool. The procedure is performed by a surgeon in a hospital and anesthesia is used. More information about these procedures can be found in the Bowel Diversion fact sheet. Electrical Stimulation Electrical stimulation, also called sacral nerve stimulation or neuromodulation, involves placing electrodes in the sacral nerves to the anus and rectum and continuously stimulating the nerves with electrical pulses. The sacral nerves connect to the part of the spine in the hip area. A battery-operated stimulator is placed beneath the skin. Based on the persons response, the health care provider can adjust the amount of stimulation so it works best for that person. The person can turn the stimulator on or off at any time. The procedure is performed in an outpatient center using local anesthesia.

### Question: What are the stages of AIDS-Related Lymphoma ? ### Response:

Key Points - After AIDS-related lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. - There are three ways that cancer spreads in the body. - Stages of AIDS-related lymphoma may include E and S. - The following stages are used for AIDS-related lymphoma: - Stage I - Stage II - Stage III - Stage IV - For treatment, AIDS-related lymphomas are grouped based on where they started in the body, as follows: - Peripheral/systemic lymphoma - Primary CNS lymphoma After AIDS-related lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. The process used to find out if cancer cells have spread within the lymph system 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, but AIDS-related lymphoma is usually advanced when it is diagnosed. The following tests and procedures may be used in the staging process: - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. The blood sample will be checked for the level of LDH (lactate dehydrogenase). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the lung, lymph nodes, and liver, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - MRI (magnetic resonance imaging) with gadolinium : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into the patient through a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Lumbar puncture : A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that the cancer has spread to the brain and spinal cord. The sample may also be checked for Epstein-Barr virus. This procedure is also called an LP or spinal tap. 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. Stages of AIDS-related lymphoma may include E and S. AIDS-related lymphoma may be described as follows: - E: "E" stands for extranodal and means the cancer is found in an area or organ other than the lymph nodes or has spread to tissues beyond, but near, the major lymphatic areas. - S: "S" stands for spleen and means the cancer is found in the spleen. The following stages are used for AIDS-related lymphoma: Stage I Stage I AIDS-related lymphoma is divided into stage I and stage IE. - Stage I: Cancer is found in one lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen). - Stage IE: Cancer is found in one organ or area outside the lymph nodes. Stage II Stage II AIDS-related lymphoma is divided into stage II and stage IIE. - Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm. Cancer is also found outside the lymph nodes in one organ or area on the same side of the diaphragm as the affected lymph nodes. Stage III Stage III AIDS-related lymphoma is divided into stage III, stage IIIE, stage IIIS, and stage IIIE+S. - Stage III: Cancer is found in lymph node groups above and below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIIE: Cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area. - Stage IIIS: Cancer is found in lymph node groups above and below the diaphragm, and in the spleen. - Stage IIIE+S: Cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area, and in the spleen. Stage IV In stage IV AIDS-related lymphoma, the cancer: - is found throughout one or more organs that are not part of a lymphatic area (lymph node group, tonsils and nearby tissue, thymus, or spleen) and may be in lymph nodes near those organs; or - is found in one organ that is not part of a lymphatic area and has spread to organs or lymph nodes far away from that organ; or - is found in the liver, bone marrow, cerebrospinal fluid (CSF), or lungs (other than cancer that has spread to the lungs from nearby areas). Patients who are infected with the Epstein-Barr virus or whose AIDS-related lymphoma affects the bone marrow have an increased risk of the cancer spreading to the central nervous system (CNS). For treatment, AIDS-related lymphomas are grouped based on where they started in the body, as follows: Peripheral/systemic lymphoma Lymphoma that starts in the lymph system or elsewhere in the body, other than the brain, is called peripheral/systemic lymphoma. It may spread throughout the body, including to the brain or bone marrow. It is often diagnosed in an advanced stage. Primary CNS lymphoma Primary CNS lymphoma starts in the central nervous system (brain and spinal cord). It is linked to the Epstein-Barr virus. Lymphoma that starts somewhere else in the body and spreads to the central nervous system is not primary CNS lymphoma.

### Question: What are the stages of Bile Duct Cancer (Cholangiocarcinoma) ? ### Response:

Key Points - The results of diagnostic and staging tests are used to find out if cancer cells have spread. - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - Stages are used to describe the different types of bile duct cancer. - Intrahepatic bile duct cancer - Perihilar bile duct cancer - Distal extrahepatic bile duct cancer - The following groups are used to plan treatment: - Resectable (localized) bile duct cancer - Unresectable, metastatic, or recurrent bile duct cancer The results of diagnostic and staging tests are used to find out if cancer cells have spread. The process used to find out if cancer has spread to other parts of the body is called staging. For bile duct cancer, the information gathered from tests and procedures is used to plan treatment, including whether the tumor can be removed by surgery. 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 bile duct cancer spreads to the liver, the cancer cells in the liver are actually bile duct cancer cells. The disease is metastatic bile duct cancer, not liver cancer. Stages are used to describe the different types of bile duct cancer. Intrahepatic bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the intrahepatic bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: There is one tumor that has spread into the intrahepatic bile duct and it has not spread into any blood vessels. - Stage II: There is one tumor that has spread through the wall of the bile duct and into a blood vessel, or there are multiple tumors that may have spread into a blood vessel. - Stage III: The tumor has spread through the tissue that lines the abdominal wall or has spread to organs or tissues near the liver such as the duodenum, colon, and stomach. - Stage IV: Stage IV is divided into stage IVA and stage IVB. - Stage IVA: The cancer has spread along the outside of the intrahepatic bile ducts or the cancer has spread to nearby lymph nodes. - Stage IVB: The cancer has spread to organs in other parts of the body. Perihilar bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the perihilar bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: Cancer has formed in the innermost layer of the wall of the perihilar bile duct and has spread into the muscle layer or fibrous tissue layer of the wall. - Stage II: Cancer has spread through the wall of the perihilar bile duct to nearby fatty tissue or to the liver. - Stage III: Stage III is divided into stage IIIA and stage IIIB. - Stage IIIA: Cancer has spread to branches on one side of the hepatic artery or of the portal vein. - Stage IIIB: Cancer has spread to nearby lymph nodes. Cancer may have spread into the wall of the perihilar bile duct or through the wall to nearby fatty tissue, the liver, or to branches on one side of the hepatic artery or of the portal vein. - Stage IV: Stage IV is divided into stage IVA and stage IVB. - Stage IVA: Cancer has spread to one or more of the following: - the main part of the portal vein and/or common hepatic artery; - the branches of the portal vein and/or common hepatic artery on both sides; - the right hepatic duct and the left branch of the hepatic artery or of the portal vein; - the left hepatic duct and the right branch of the hepatic artery or of the portal vein. Cancer may have spread to nearby lymph nodes. - Stage IVB: Cancer has spread to lymph nodes in more distant parts of the abdomen, or to organs in other parts of the body. Distal extrahepatic bile duct cancer - Stage 0: Abnormal cells are found in the innermost layer of tissue lining the distal extrahepatic bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. - Stage I: Stage I is divided into stage IA and stage IB. - Stage IA: Cancer has formed and is found in the distal extrahepatic bile duct wall only. - Stage IB: Cancer has formed and has spread through the wall of the distal extrahepatic bile duct but has not spread to nearby organs. - Stage II: Stage II is divided into stage IIA and stage IIB. - Stage IIA: Cancer has spread from the distal extrahepatic bile duct to the gallbladder, pancreas, duodenum, or other nearby organs. - Stage IIB: Cancer has spread from the distal extrahepatic bile duct to nearby lymph nodes. Cancer may have spread through the wall of the duct or to nearby organs. - Stage III: Cancer has spread to the large vessels that carry blood to the organs in the abdomen. Cancer may have spread to nearby lymph nodes. - Stage IV: Cancer has spread to organs in distant parts of the body. The following groups are used to plan treatment: Resectable (localized) bile duct cancer The cancer is in an area, such as the lower part of the common bile duct or perihilar area, where it can be removed completely by surgery. Unresectable, metastatic, or recurrent bile duct cancer Unresectable cancer cannot be removed completely by surgery. Most patients with bile duct cancer cannot have their cancer completely removed by surgery. Metastasis is the spread of cancer from the primary site (place where it started) to other places in the body. Metastatic bile duct cancer may have spread to the liver, other parts of the abdominal cavity, or to distant parts of the body. Recurrent bile duct cancer is cancer that has recurred (come back) after it has been treated. The cancer may come back in the bile ducts, liver, or gallbladder. Less often, it may come back in distant parts of the body.

### Question: What causes Overweight and Obesity ? ### Response:

Lack of Energy Balance A lack of energy balance most often causes overweight and obesity. Energy balance means that your energy IN equals your energy OUT. Energy IN is the amount of energy or calories you get from food and drinks. Energy OUT is the amount of energy your body uses for things like breathing, digesting, and being physically active. To maintain a healthy weight, your energy IN and OUT don't have to balance exactly every day. It's the balance over time that helps you maintain a healthy weight. The same amount of energy IN and energy OUT over time = weight stays the same More energy IN than energy OUT over time = weight gain More energy OUT than energy IN over time = weight loss Overweight and obesity happen over time when you take in more calories than you use. Other Causes An Inactive Lifestyle Many Americans aren't very physically active. One reason for this is that many people spend hours in front of TVs and computers doing work, schoolwork, and leisure activities. In fact, more than 2 hours a day of regular TV viewing time has been linked to overweight and obesity. Other reasons for not being active include: relying on cars instead of walking, fewer physical demands at work or at home because of modern technology and conveniences, and lack of physical education classes in schools. People who are inactive are more likely to gain weight because they don't burn the calories that they take in from food and drinks. An inactive lifestyle also raises your risk for coronary heart disease, high blood pressure, diabetes, colon cancer, and other health problems. Environment Our environment doesn't support healthy lifestyle habits; in fact, it encourages obesity. Some reasons include: Lack of neighborhood sidewalks and safe places for recreation. Not having area parks, trails, sidewalks, and affordable gyms makes it hard for people to be physically active. Work schedules. People often say that they don't have time to be physically active because of long work hours and time spent commuting. Oversized food portions. Americans are exposed to huge food portions in restaurants, fast food places, gas stations, movie theaters, supermarkets, and even at home. Some of these meals and snacks can feed two or more people. Eating large portions means too much energy IN. Over time, this will cause weight gain if it isn't balanced with physical activity. Lack of access to healthy foods. Some people don't live in neighborhoods that have supermarkets that sell healthy foods, such as fresh fruits and vegetables. Or, for some people, these healthy foods are too costly. Food advertising. Americans are surrounded by ads from food companies. Often children are the targets of advertising for high-calorie, high-fat snacks and sugary drinks. The goal of these ads is to sway people to buy these high-calorie foods, and often they do. Genes and Family History Studies of identical twins who have been raised apart show that genes have a strong influence on a person's weight. Overweight and obesity tend to run in families. Your chances of being overweight are greater if one or both of your parents are overweight or obese. Your genes also may affect the amount of fat you store in your body and where on your body you carry the extra fat. Because families also share food and physical activity habits, a link exists between genes and the environment. Children adopt the habits of their parents. A child who has overweight parents who eat high-calorie foods and are inactive will likely become overweight too. However, if the family adopts healthy food and physical activity habits, the child's chance of being overweight or obese is reduced. Health Conditions Some hormone problems may cause overweight and obesity, such as underactive thyroid (hypothyroidism), Cushing's syndrome, and polycystic ovarian syndrome (PCOS). Underactive thyroid is a condition in which the thyroid gland doesn't make enough thyroid hormone. Lack of thyroid hormone will slow down your metabolism and cause weight gain. You'll also feel tired and weak. Cushing's syndrome is a condition in which the body's adrenal glands make too much of the hormone cortisol. Cushing's syndrome also can develop if a person takes high doses of certain medicines, such as prednisone, for long periods. People who have Cushing's syndrome gain weight, have upper-body obesity, a rounded face, fat around the neck, and thin arms and legs. PCOS is a condition that affects about 510 percent of women of childbearing age. Women who have PCOS often are obese, have excess hair growth, and have reproductive problems and other health issues. These problems are caused by high levels of hormones called androgens. Medicines Certain medicines may cause you to gain weight. These medicines include some corticosteroids, antidepressants, and seizure medicines. These medicines can slow the rate at which your body burns calories, increase your appetite, or cause your body to hold on to extra water. All of these factors can lead to weight gain. Emotional Factors Some people eat more than usual when they're bored, angry, or stressed. Over time, overeating will lead to weight gain and may cause overweight or obesity. Smoking Some people gain weight when they stop smoking. One reason is that food often tastes and smells better after quitting smoking. Another reason is because nicotine raises the rate at which your body burns calories, so you burn fewer calories when you stop smoking. However, smoking is a serious health risk, and quitting is more important than possible weight gain. Age As you get older, you tend to lose muscle, especially if you're less active. Muscle loss can slow down the rate at which your body burns calories. If you don't reduce your calorie intake as you get older, you may gain weight. Midlife weight gain in women is mainly due to aging and lifestyle, but menopause also plays a role. Many women gain about 5 pounds during menopause and have more fat around the waist than they did before. Pregnancy During pregnancy, women gain weight to support their babies growth and development. After giving birth, some women find it hard to lose the weight. This may lead to overweight or obesity, especially after a few pregnancies. Lack of Sleep Research shows that lack of sleep increases the risk of obesity. For example, one study of teenagers showed that with each hour of sleep lost, the odds of becoming obese went up. Lack of sleep increases the risk of obesity in other age groups as well. People who sleep fewer hours also seem to prefer eating foods that are higher in calories and carbohydrates, which can lead to overeating, weight gain, and obesity. Sleep helps maintain a healthy balance of the hormones that make you feel hungry (ghrelin) or full (leptin). When you don't get enough sleep, your level of ghrelin goes up and your level of leptin goes down. This makes you feel hungrier than when you're well-rested. Sleep also affects how your body reacts to insulin, the hormone that controls your blood glucose (sugar) level. Lack of sleep results in a higher than normal blood sugar level, which may increase your risk for diabetes. For more information, go to the Health Topics Sleep Deprivation and Deficiency article.

### Question: How to diagnose Fanconi Anemia ? ### Response:

People who have Fanconi anemia (FA) are born with the disorder. They may or may not show signs or symptoms of it at birth. For this reason, FA isn't always diagnosed when a person is born. In fact, most people who have the disorder are diagnosed between the ages of 2 and 15 years. The tests used to diagnose FA depend on a person's age and symptoms. In all cases, medical and family histories are an important part of diagnosing FA. However, because FA has many of the same signs and symptoms as other diseases, only genetic testing can confirm its diagnosis. Specialists Involved A geneticist is a doctor or scientist who studies how genes work and how diseases and traits are passed from parents to children through genes. Geneticists do genetic testing for FA. They also can provide counseling about how FA is inherited and the types of prenatal (before birth) testing used to diagnose it. An obstetrician may detect birth defects linked to FA before your child is born. An obstetrician is a doctor who specializes in providing care for pregnant women. After your child is born, a pediatrician also can help find out whether your child has FA. A pediatrician is a doctor who specializes in treating children and teens. A hematologist (blood disease specialist) also may help diagnose FA. Family and Medical Histories FA is an inherited disease. Some parents are aware that their family has a medical history of FA, even if they don't have the disease. Other parents, especially if they're FA carriers, may not be aware of a family history of FA. Many parents may not know that FA can be passed from parents to children. Knowing your family medical history can help your doctor diagnose whether you or your child has FA or another condition with similar symptoms. If your doctor thinks that you, your siblings, or your children have FA, he or she may ask you detailed questions about: Any personal or family history of anemia Any surgeries youve had related to the digestive system Any personal or family history of immune disorders Your appetite, eating habits, and any medicines you take If you know your family has a history of FA, or if your answers to your doctor's questions suggest a possible diagnosis of FA, your doctor will recommend further testing. Diagnostic Tests and Procedures The signs and symptoms of FA aren't unique to the disease. They're also linked to many other diseases and conditions, such as aplastic anemia. For this reason, genetic testing is needed to confirm a diagnosis of FA. Genetic tests for FA include the following. Chromosome Breakage Test This is the most common test for FA. It's available only in special laboratories (labs). It shows whether your chromosomes (long chains of genes) break more easily than normal. Skin cells sometimes are used for the test. Usually, though, a small amount of blood is taken from a vein in your arm using a needle. A technician combines some of the blood cells with certain chemicals. If you have FA, the chromosomes in your blood sample break and rearrange when mixed with the test chemicals. This doesn't happen in the cells of people who don't have FA. Cytometric Flow Analysis Cytometric flow analysis, or CFA, is done in a lab. This test examines how chemicals affect your chromosomes as your cells grow and divide. Skin cells are used for this test. A technician mixes the skin cells with chemicals that can cause the chromosomes in the cells to act abnormally. If you have FA, your cells are much more sensitive to these chemicals. The chromosomes in your skin cells will break at a high rate during the test. This doesn't happen in the cells of people who don't have FA. Mutation Screening A mutation is an abnormal change in a gene or genes. Geneticists and other specialists can examine your genes, usually using a sample of your skin cells. With special equipment and lab processes, they can look for gene mutations that are linked to FA. Diagnosing Different Age Groups Before Birth (Prenatal) If your family has a history of FA and you get pregnant, your doctor may want to test you or your fetus for FA. Two tests can be used to diagnose FA in a developing fetus: amniocentesis (AM-ne-o-sen-TE-sis) and chorionic villus (ko-re-ON-ik VIL-us) sampling (CVS). Both tests are done in a doctor's office or hospital. Amniocentesis is done 15 to 18 weeks after a pregnant woman's last period. A doctor uses a needle to remove a small amount of fluid from the sac around the fetus. A technician tests chromosomes (chains of genes) from the fluid sample to see whether they have faulty genes associated with FA. CVS is done 10 to 12 weeks after a pregnant woman's last period. A doctor inserts a thin tube through the vagina and cervix to the placenta (the temporary organ that connects the fetus to the mother). The doctor removes a tissue sample from the placenta using gentle suction. The tissue sample is sent to a lab to be tested for genetic defects associated with FA. At Birth Three out of four people who inherit FA are born with birth defects. If your baby is born with certain birth defects, your doctor may recommend genetic testing to confirm a diagnosis of FA. For more information about these defects, go to What Are the Signs and Symptoms of Fanconi Anemia? Childhood and Later Some people who have FA are not born with birth defects. Doctors may not diagnose them with the disorder until signs of bone marrow failure or cancer occur. This usually happens within the first 10 years of life. Signs of bone marrow failure most often begin between the ages of 3 and 12 years, with 7 to 8 years as the most common ages. However, 10 percent of children who have FA aren't diagnosed until after 16 years of age. If your bone marrow is failing, you may have signs of aplastic anemia. FA is one type of aplastic anemia. In aplastic anemia, your bone marrow stops making or doesn't make enough of all three types of blood cells: red blood cells, white blood cells, and platelets. Aplastic anemia can be inherited or acquired after birth through exposure to chemicals, radiation, or medicines. Doctors diagnose aplastic anemia using: Family and medical histories and a physical exam. A complete blood count (CBC) to check the number, size, and condition of your red blood cells. The CBC also checks numbers of white blood cells and platelets. A reticulocyte (re-TIK-u-lo-site) count. This test counts the number of new red blood cells in your blood to see whether your bone marrow is making red blood cells at the proper rate. Bone marrow tests. For a bone marrow aspiration, a small amount of liquid bone marrow is removed and tested to see whether it's making enough blood cells. For a bone marrow biopsy, a small amount of bone marrow tissue is removed and tested to see whether it's making enough blood cells. If you or your child is diagnosed with aplastic anemia, your doctor will want to find the cause. If your doctor suspects you have FA, he or she may recommend genetic testing. For more information, go to the Health Topics Aplastic Anemia article.

### Question: What are the treatments for Childhood Brain and Spinal Cord Tumors ? ### Response:

Key Points - There are different types of treatment for children with brain and spinal cord tumors. - Children with brain or spinal cord tumors should have their treatment planned by a team of health care providers who are experts in treating childhood brain and spinal cord tumors. - Childhood brain and spinal cord tumors may cause signs or symptoms that begin before the cancer is diagnosed and continue for months or years. - Some cancer treatments cause side effects months or years after treatment has ended. - Three types of standard treatment are used: - Surgery - Radiation therapy - Chemotherapy - New types of treatment are being tested in clinical trials. - High-dose chemotherapy with stem cell transplant - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their cancer treatment. - Follow-up tests may be needed. There are different types of treatment for children with brain and spinal cord tumors. Different types of treatment are available for children with brain and spinal cord tumors. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Because cancer in children is rare, taking part in a clinical trial should be considered. Clinical trials are taking place in many parts of the country. Some clinical trials are open only to patients who have not started treatment. Children with brain or spinal cord tumors should have their treatment planned by a team of health care providers who are experts in treating childhood brain and spinal cord tumors. Treatment will be overseen by a pediatric oncologist, a doctor who specializes in treating children with cancer. The pediatric oncologist works with other health care providers who are experts in treating children with brain tumors and who specialize in certain areas of medicine. These may include the following specialists: - Pediatrician. - Neurosurgeon. - Neurologist. - Neuro-oncologist. - Neuropathologist. - Neuroradiologist. - Radiation oncologist. - Endocrinologist. - Psychologist. - Ophthalmologist. - Rehabilitation specialist. - Social worker. - Nurse specialist. Childhood brain and spinal cord tumors may cause signs or symptoms that begin before the cancer is diagnosed and continue for months or years. Childhood brain and spinal cord tumors may cause signs or symptoms that continue for months or years. Signs or symptoms caused by the tumor may begin before diagnosis. Signs or symptoms caused by treatment may begin during or right after treatment. Some cancer treatments cause side effects months or years after treatment has ended. These are called late effects. Late effects of cancer treatment may include the following: - Physical problems. - Changes in mood, feelings, thinking, learning, or memory. - Second cancers (new types of cancer). Some late effects may be treated or controlled. It is important to talk with your child's doctors about the effects cancer treatment can have on your child. (See the PDQ summary on Late Effects of Treatment for Childhood Cancer for more information). Three types of standard treatment are used: Surgery Surgery may be used to diagnose and treat childhood brain and spinal cord tumors. See the General Information section of this summary. Radiation therapy Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy: - External radiation therapy uses a machine outside the body to send radiation toward the cancer. - Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type of cancer being treated. External radiation therapy is used to treat childhood brain and spinal cord tumors. Chemotherapy Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. When chemotherapy is taken by mouth or injected into a vein or muscle, the drugs enter the bloodstream and can reach cancer cells throughout the body (systemic chemotherapy). When chemotherapy is placed directly in the cerebrospinal fluid, an organ, or a body cavity such as the abdomen, the drugs mainly affect cancer cells in those areas (regional chemotherapy). The way the chemotherapy is given depends on the type and stage of the cancer being treated. Anticancer drugs given by mouth or vein to treat brain and spinal cord tumors cannot cross the blood-brain barrier and enter the fluid that surrounds the brain and spinal cord. Instead, an anticancer drug is injected into the fluid-filled space to kill cancer cells there. This is called intrathecal chemotherapy. New types of treatment are being tested in clinical trials. This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website. High-dose chemotherapy with stem cell transplant High-dose chemotherapy with stem cell transplant is a way of giving high doses of chemotherapy and replacing blood -forming cells destroyed by the cancer treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of the patient or a donor and are frozen and stored. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the bodys blood cells. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their cancer treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. Information about clinical trials is available from the NCI website. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your child's condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

### Question: What are the treatments for Hemophilia ? ### Response:

Treatment With Replacement Therapy The main treatment for hemophilia is called replacement therapy. Concentrates of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) are slowly dripped or injected into a vein. These infusions help replace the clotting factor that's missing or low. Clotting factor concentrates can be made from human blood. The blood is treated to prevent the spread of diseases, such as hepatitis. With the current methods of screening and treating donated blood, the risk of getting an infectious disease from human clotting factors is very small. To further reduce the risk, you or your child can take clotting factor concentrates that aren't made from human blood. These are called recombinant clotting factors. Clotting factors are easy to store, mix, and use at homeit only takes about 15 minutes to receive the factor. You may have replacement therapy on a regular basis to prevent bleeding. This is called preventive or prophylactic (PRO-fih-lac-tik) therapy. Or, you may only need replacement therapy to stop bleeding when it occurs. This use of the treatment, on an as-needed basis, is called demand therapy. Demand therapy is less intensive and expensive than preventive therapy. However, there's a risk that bleeding will cause damage before you receive the demand therapy. Complications of Replacement Therapy Complications of replacement therapy include: Developing antibodies (proteins) that attack the clotting factor Developing viral infections from human clotting factors Damage to joints, muscles, or other parts of the body resulting from delays in treatment Antibodies to the clotting factor. Antibodies can destroy the clotting factor before it has a chance to work. This is a very serious problem. It prevents the main treatment for hemophilia (replacement therapy) from working. These antibodies, also called inhibitors, develop in about 2030 percent of people who have severe hemophilia A. Inhibitors develop in 25 percent of people who have hemophilia B. When antibodies develop, doctors may use larger doses of clotting factor or try different clotting factor sources. Sometimes the antibodies go away. Researchers are studying new ways to deal with antibodies to clotting factors. Viruses from human clotting factors. Clotting factors made from human blood can carry the viruses that cause HIV/AIDS and hepatitis. However, the risk of getting an infectious disease from human clotting factors is very small due to: Careful screening of blood donors Testing of donated blood products Treating donated blood products with a detergent and heat to destroy viruses Vaccinating people who have hemophilia for hepatitis A and B Damage to joints, muscles, and other parts of the body. Delays in treatment can cause damage such as: Bleeding into a joint. If this happens many times, it can lead to changes in the shape of the joint and impair the joint's function. Swelling of the membrane around a joint. Pain, swelling, and redness of a joint. Pressure on a joint from swelling, which can destroy the joint. Home Treatment With Replacement Therapy You can do both preventive (ongoing) and demand (as-needed) replacement therapy at home. Many people learn to do the infusions at home for their child or for themselves. Home treatment has several advantages: You or your child can get quicker treatment when bleeding happens. Early treatment lowers the risk of complications. Fewer visits to the doctor or emergency room are needed. Home treatment costs less than treatment in a medical care setting. Home treatment helps children accept treatment and take responsibility for their own health. Discuss options for home treatment with your doctor or your child's doctor. A doctor or other health care provider can teach you the steps and safety procedures for home treatment. Hemophilia treatment centers are another good resource for learning about home treatment (discussed in "Living With Hemophilia). Doctors can surgically implant vein access devices to make it easier for you to access a vein for treatment with replacement therapy. These devices can be helpful if treatment occurs often. However, infections can be a problem with these devices. Your doctor can help you decide whether this type of device is right for you or your child. Other Types of Treatment Desmopressin Desmopressin (DDAVP) is a man-made hormone used to treat people who have mild hemophilia A. DDAVP isn't used to treat hemophilia B or severe hemophilia A. DDAVP stimulates the release of stored factor VIII and von Willebrand factor; it also increases the level of these proteins in your blood. Von Willebrand factor carries and binds factor VIII, which can then stay in the bloodstream longer. DDAVP usually is given by injection or as nasal spray. Because the effect of this medicine wears off if it's used often, the medicine is given only in certain situations. For example, you may take this medicine prior to dental work or before playing certain sports to prevent or reduce bleeding. Antifibrinolytic Medicines Antifibrinolytic medicines (including tranexamic acid and epsilon aminocaproic acid) may be used with replacement therapy. They're usually given as a pill, and they help keep blood clots from breaking down. These medicines most often are used before dental work or to treat bleeding from the mouth or nose or mild intestinal bleeding. Gene Therapy Researchers are trying to find ways to correct the faulty genes that cause hemophilia. Gene therapy hasn't yet developed to the point that it's an accepted treatment for hemophilia. However, researchers continue to test gene therapy in clinical trials. For more information, go to the "Clinical Trials" section of this article. Treatment of a Specific Bleeding Site Pain medicines, steroids, and physical therapy may be used to reduce pain and swelling in an affected joint. Talk with your doctor or pharmacist about which medicines are safe for you to take. Which Treatment Is Best for You? The type of treatment you or your child receives depends on several things, including how severe the hemophilia is, the activities you'll be doing, and the dental or medical procedures you'll be having. Mild hemophiliaReplacement therapy usually isn't needed for mild hemophilia. Sometimes, though, DDAVP is given to raise the body's level of factor VIII. Moderate hemophiliaYou may need replacement therapy only when bleeding occurs or to prevent bleeding that could occur when doing certain activities. Your doctor also may recommend DDAVP prior to having a procedure or doing an activity that increases the risk of bleeding. Severe hemophiliaYou usually need replacement therapy to prevent bleeding that could damage your joints, muscles, or other parts of your body. Typically, replacement therapy is given at home two or three times a week. This preventive therapy usually is started in patients at a young age and may need to continue for life. For both types of hemophilia, getting quick treatment for bleeding is important. Quick treatment can limit damage to your body. If you or your child has hemophilia, learn to recognize signs of bleeding. Other family members also should learn to watch for signs of bleeding in a child who has hemophilia. Children sometimes ignore signs of bleeding because they want to avoid the discomfort of treatment.

### Question: How to prevent Diabetes ? ### Response:

The two most common forms of diabetes are type 1 and type 2. Currently, there is no way to delay or prevent type 1 diabetes. However, research has shown that type 2 diabetes can be prevented or delayed in people at risk for the disease. Preventing type 2 diabetes can mean a healthier and longer life without serious complications from the disease such as heart disease, stroke, blindness, kidney failure, and amputations. Preventing Type 2 Diabetes Before people develop type 2 diabetes, they usually have prediabetes -- a condition in which blood glucose levels are higher than normal, but not yet high enough for a diagnosis of diabetes. The good news is that if you have prediabetes, there are ways to reduce your risk of getting type 2 diabetes. With modest weight loss and moderate physical activity, you can delay or prevent type 2 diabetes Benefits of Weight Loss and Exercise The Diabetes Prevention Program (DPP) is a landmark study by the National Institute of Diabetes and Digestive and Kidney Diseases. DPP researchers found that adults at high risk for type 2 diabetes were able to cut their risk in half by losing a modest amount of weight and being active almost every day. This means losing 5 to 7 percent of body weight (that's 10 pounds if you weigh 200 pounds) and getting 150 minutes of physical activity a week. The drug metformin reduced the risk of type 2 diabetes by 34 percent but was more effective in younger and heavier adults. (Watch the video to learn more about preventing type 2 diabetes. To enlarge the video, click the brackets in the lower right-hand corner. To reduce the video, press the Escape (Esc) button on your keyboard.) The benefits of weight loss and regular exercise have long-lasting value. In a DPP follow-up trial known as the Diabetes Prevention Program Outcome Study (DPPOS), people at risk of type 2 diabetes who kept off the weight they had lost and who continued to exercise regularly delayed the onset of type 2 diabetes by about 4 years. The DPP study also showed that modest weight loss (achieved by following a low calorie, low-fat diet) and moderate physical activity were especially effective in preventing or delaying the development of diabetes in older people. In fact, people over the age of 60 were able to reduce their risk for developing type 2 diabetes by 71 percent. How to Lower Your Risk Making modest lifestyle changes can help prevent or delay type 2 diabetes in people who are at risk. Here are some tips. Reach and Maintain a Reasonable Body Weight Your weight affects your health in many ways. Being overweight can keep your body from making and using insulin properly. It can also cause high blood pressure. The Body Mass Index chart (seen here) can be used to find out whether someone is normal weight, overweight, or obese. Body mass index is a measurement of body weight relative to height for adults age 20 or older. To use the chart - find the person's height in the left-hand column - move across the row to find the number closest to the person's weight - find the number at the top of that column - The number at the top of the column is the persons BMI. find the person's height in the left-hand column move across the row to find the number closest to the person's weight find the number at the top of that column The number at the top of the column is the persons BMI. The words above the BMI number indicate whether the person is normal weight, overweight, or obese. People who are overweight or obese should consider talking with a health care provider about ways to lose weight and reduce the risk of diabetes. The BMI has certain limitations. The BMI may overestimate body fat in athletes and others who have a muscular build and underestimate body fat in older adults and others who have lost muscle. Waist Measurement. In addition to weight, the location of excess fat on the body can be important. A waist measurement of 40 inches or more for men and 35 inches or more for women is linked to insulin resistance and increases a persons risk for type 2 diabetes. This is true even if a persons body mass index (BMI) falls within the normal range. To measure the waist, a person should - place a tape measure around the bare abdomen just above the hip bone - make sure the tape is snug but isnt digging into the skin and is parallel to the floor - relax, exhale, and measure. place a tape measure around the bare abdomen just above the hip bone make sure the tape is snug but isnt digging into the skin and is parallel to the floor relax, exhale, and measure. Make Healthy Food Choices What you eat has a big impact on your weight and overall health. By developing healthy eating habits, you can help manage your body weight, blood pressure, and cholesterol. Reducing portion size, increasing the amount of fiber you consume (by eating more fruits and vegetables) and limiting fatty and salty foods are key to a healthy diet. Here are more tips for eating well with diabetes. - Make a diabetes meal plan with help from your health care team. - Choose foods that are lower in calories, saturated fat, trans fat, sugar, and salt. - Eat foods with more fiber, such as whole grain cereals, breads, crackers, rice, or pasta. - Choose foods such as fruits, vegetables, whole grains, bread and cereals, and low-fat or skim milk and cheese. - Drink water instead of juice and regular soda. - When eating a meal, fill half of your plate with fruits and vegetables, one quarter with a lean protein, such as beans, or chicken or turkey without the skin, and one quarter with a whole grain, such as brown rice or whole wheat pasta.

For more about healthy eating and older adults see "Eating Well as You Get Older." Be Physically Active Get at least 30 minutes of exercise at least five days a week. Regular exercise reduces diabetes risk in several ways. It - helps you lose weight - controls your cholesterol and blood pressure - improves your body's use of insulin. helps you lose weight controls your cholesterol and blood pressure improves your body's use of insulin. Many people make walking part of their daily routine because its easy, fun and convenient. But you can choose any activity that gets you moving. Its fine to break up your 30 minutes of exercise into smaller increments, such as three 10-minute periods. Check with your doctor before beginning any exercise program.

### Question: How to diagnose Fecal Incontinence ? ### Response:

Health care providers diagnose fecal incontinence based on a persons medical history, physical exam, and medical test results. In addition to a general medical history, the health care provider may ask the following questions: - When did fecal incontinence start? - How often does fecal incontinence occur? - How much stool leaks? Does the stool just streak the underwear? Does just a little bit of solid or liquid stool leak out or does complete loss of bowel control occur? - Does fecal incontinence involve a strong urge to have a bowel movement or does it happen without warning? - For people with hemorrhoids, do hemorrhoids bulge through the anus? Do the hemorrhoids pull back in by themselves, or do they have to be pushed in with a finger? - How does fecal incontinence affect daily life? - Is fecal incontinence worse after eating? Do certain foods seem to make fecal incontinence worse? - Can passing gas be controlled? People may want to keep a stool diary for several weeks before their appointment so they can answer these questions. A stool diary is a chart for recording daily bowel movement details. A sample stool diary is available on the Bowel Control Awareness Campaign website at www.bowelcontrol.nih.gov. The person may be referred to a doctor who specializes in problems of the digestive system, such as a gastroenterologist, proctologist, or colorectal surgeon, or a doctor who specializes in problems of the urinary and reproductive systems, such as a urologist or urogynecologist. The specialist will perform a physical exam and may suggest one or more of the following tests: - anal manometry - anal ultrasound - magnetic resonance imaging (MRI) - defecography - flexible sigmoidoscopy or colonoscopy - anal electromyography (EMG) Anal manometry. Anal manometry uses pressure sensors and a balloon that can be inflated in the rectum to check the sensitivity and function of the rectum. Anal manometry also checks the tightness of the anal sphincter muscles around the anus. To prepare for this test, the person should use an enema and not eat anything 2 hours before the test. An enema involves flushing water or a laxative into the anus using a special squirt bottle. A laxative is medication that loosens stool and increases bowel movements. For this test, a thin tube with a balloon on its tip and pressure sensors below the balloon is inserted into the anus until the balloon is in the rectum and pressure sensors are located in the anal canal. The tube is slowly pulled back through the sphincter muscle to measure muscle tone and contractions. No anesthesia is needed for this test, which takes about 30 minutes. Anal ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. An anal ultrasound is specific to the anus and rectum. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. The images can show the structure of the anal sphincter muscles. MRI. MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed, though people with a fear of confined spaces may be given medication to help them relax. An MRI may include the injection of special dye, called contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. MRIs can show problems with the anal sphincter muscles. MRI is an alternative to anal ultrasound that may provide more detailed information, especially about the external anal sphincter. Defecography. This x ray of the area around the anus and rectum shows how well the person can hold and evacuate stool. The test also identifies structural changes in the rectum and anus such as rectocele and rectal prolapse. To prepare for the test, the person uses two enemas and does not eat anything 2 hours prior to the test. During the test, the health care provider fills the rectum with a soft paste that shows up on x rays and is the same consistency as stool. The person sits on a toilet inside an x-ray machine. The person is first asked to pull in and squeeze the sphincter muscles to prevent leakage and then to strain as if having a bowel movement. The radiologist studies the x rays to identify problems with the rectum, anus, and pelvic floor muscles. Flexible sigmoidoscopy or colonoscopy. These tests are used to help diagnose problems causing fecal incontinence. The tests are similar, but colonoscopy is used to view the rectum and entire colon, while flexible sigmoidoscopy is used to view just the rectum and lower colon. These tests are performed at a hospital or outpatient center by a gastroenterologist. For both tests, a health care provider will provide written bowel prep instructions to follow at home. The person may be asked to follow a clear liquid diet for 1 to 3 days before either test. A laxative may be required the night before the test. One or more enemas may be required the night before and about 2 hours before the test. In most cases, people will be given light anesthesia, and possibly pain medication, to help them relax during flexible sigmoidoscopy. Anesthesia is used for colonoscopy. For either test, the person will lie on a table while the gastroenterologist inserts a flexible tube into the anus. A small camera on the tube sends a video image of the intestinal lining to a computer screen. The test can show problems in the lower GI tract that may be causing the bowel control problem. The gastroenterologist may also perform a biopsy, a procedure that involves taking a piece of tissue from the bowel lining for examination with a microscope. The person will not feel the biopsy. A pathologista doctor who specializes in diagnosing diseasesexamines the tissue in a lab to confirm the diagnosis. Cramping or bloating may occur during the first hour after these tests. Driving is not permitted for 24 hours after flexible sigmoidoscopy or colonoscopy to allow the anesthesia time to wear off. Before the appointment, a person should make plans for a ride home. Full recovery is expected by the next day and the person is able to go back to a normal diet. Anal EMG. Anal EMG checks the health of the pelvic floor muscles and the nerves that control the muscles. The health care provider inserts a very thin needle electrode through the skin into the muscle. The electrode on the needle picks up the electrical activity given off by the muscles and shows it as images on a monitor or sounds through a speaker. An alternative type of anal EMG uses stainless steel plates attached to the sides of a plastic plug instead of a needle. The plug is inserted into the anal canal to measure the electrical activity of the external anal sphincter and other pelvic floor muscles. The average amount of electrical activity when the person relaxes quietly, squeezes to prevent a bowel movement, and strains to have a bowel movement shows whether there is damage to the nerves that control the external sphincter and pelvic floor muscles.

### Question: How to diagnose Cushing's Syndrome ? ### Response:

Diagnosis is based on a review of a person's medical history, a physical examination, and laboratory tests. X rays of the adrenal or pituitary glands can be useful in locating tumors. Tests to Diagnose Cushing's Syndrome No single lab test is perfect and usually several are needed. The three most common tests used to diagnose Cushing's syndrome are the 24-hour urinary free cortisol test, measurement of midnight plasma cortisol or late-night salivary cortisol, and the low-dose dexamethasone suppression test. Another test, the dexamethasone-corticotropin-releasing hormone test, may be needed to distinguish Cushing's syndrome from other causes of excess cortisol. - 24-hour urinary free cortisol level. In this test, a person's urine is collected several times over a 24-hour period and tested for cortisol. Levels higher than 50 to 100 micrograms a day for an adult suggest Cushing's syndrome. The normal upper limit varies in different laboratories, depending on which measurement technique is used. - Midnight plasma cortisol and late-night salivary cortisol measurements. The midnight plasma cortisol test measures cortisol concentrations in the blood. Cortisol production is normally suppressed at night, but in Cushing's syndrome, this suppression doesn't occur. If the cortisol level is more than 50 nanomoles per liter (nmol/L), Cushing's syndrome is suspected. The test generally requires a 48-hour hospital stay to avoid falsely elevated cortisol levels due to stress. However, a late-night or bedtime saliva sample can be obtained at home, then tested to determine the cortisol level. Diagnostic ranges vary, depending on the measurement technique used. - Low-dose dexamethasone suppression test (LDDST). In the LDDST, a person is given a low dose of dexamethasone, a synthetic glucocorticoid, by mouth every 6 hours for 2 days. Urine is collected before dexamethasone is administered and several times on each day of the test. A modified LDDST uses a onetime overnight dose. Cortisol and other glucocorticoids signal the pituitary to release less ACTH, so the normal response after taking dexamethasone is a drop in blood and urine cortisol levels. If cortisol levels do not drop, Cushing's syndrome is suspected. The LDDST may not show a drop in cortisol levels in people with depression, alcoholism, high estrogen levels, acute illness, or stress, falsely indicating Cushing's syndrome. On the other hand, drugs such as phenytoin and phenobarbital may cause cortisol levels to drop, falsely indicating that Cushings is not present in people who actually have the syndrome. For this reason, physicians usually advise their patients to stop taking these drugs at least 1 week before the test. - Dexamethasone-corticotropin-releasing hormone (CRH) test. Some people have high cortisol levels but do not develop the progressive effects of Cushing's syndrome, such as muscle weakness, fractures, and thinning of the skin. These people may have pseudo-Cushing's syndrome, a condition sometimes found in people who have depression or anxiety disorders, drink excess alcohol, have poorly controlled diabetes, or are severely obese. Pseudo-Cushings does not have the same long-term effects on health as Cushing's syndrome and does not require treatment directed at the endocrine glands. The dexamethasone-CRH test rapidly distinguishes pseudo-Cushing's from mild cases of Cushing's. This test combines the LDDST and a CRH stimulation test. In the CRH stimulation test, an injection of CRH causes the pituitary to secrete ACTH. Pretreatment with dexamethasone prevents CRH from causing an increase in cortisol in people with pseudo-Cushing's. Elevations of cortisol during this test suggest Cushing's syndrome. Tests to Find the Cause of Cushing's Syndrome Once Cushing's syndrome has been diagnosed, other tests are used to find the exact location of the abnormality that leads to excess cortisol production. The choice of test depends, in part, on the preference of the endocrinologist or the center where the test is performed. - CRH stimulation test. The CRH test, without pretreatment with dexamethasone, helps separate people with pituitary adenomas from those with ectopic ACTH syndrome or adrenal tumors. As a result of the CRH injection, people with pituitary adenomas usually experience a rise in blood levels of ACTH and cortisol because CRH acts directly on the pituitary. This response is rarely seen in people with ectopic ACTH syndrome and practically never in those with adrenal tumors. - high-dose dexamethasone suppression test (HDDST). The HDDST is the same as the LDDST, except it uses higher doses of dexamethasone. This test helps separate people with excess production of ACTH due to pituitary adenomas from those with ectopic ACTH-producing tumors. High doses of dexamethasone usually suppress cortisol levels in people with pituitary adenomas but not in those with ectopic ACTH-producing tumors. - Radiologic imaging: direct visualization of the endocrine glands. Imaging tests reveal the size and shape of the pituitary and adrenal glands and help determine if a tumor is present. The most common imaging tests are the computerized tomography (CT) scan and magnetic resonance imaging (MRI). A CT scan produces a series of x-ray pictures giving a cross-sectional image of a body part. MRI also produces images of internal organs but without exposing patients to ionizing radiation. Imaging procedures are used to find a tumor after a diagnosis has been made. Imaging is not used to make the diagnosis of Cushing's syndrome because benign tumors are commonly found in the pituitary and adrenal glands. These tumors, sometimes called incidentalomas, do not produce hormones in quantities that are harmful. They are not removed unless blood tests show they are a cause of symptoms or they are unusually large. Conversely, pituitary tumors may not be detectable by imaging in almost half of people who ultimately need pituitary surgery for Cushing's syndrome. - Petrosal sinus sampling. This test is not always required, but in many cases, it is the best way to distinguish pituitary from ectopic causes of Cushing's syndrome. Samples of blood are drawn from the petrosal sinuses-veins that drain the pituitary-by inserting tiny tubes through a vein in the upper thigh or groin region. A local anesthetic and mild sedation are given, and x rays are taken to confirm the correct position of the tubes. Often CRH, the hormone that causes the pituitary to release ACTH, is given during this test to improve diagnostic accuracy. Levels of ACTH in the petrosal sinuses are measured and compared with ACTH levels in a forearm vein. Higher levels of ACTH in the sinuses than in the forearm vein indicate a pituitary adenoma. Similar levels of ACTH in the petrosal sinuses and the forearm suggest ectopic ACTH syndrome.

### Question: How to diagnose Alagille Syndrome ? ### Response:

A health care provider diagnoses Alagille syndrome by performing a thorough physical exam and ordering one or more of the following tests and exams: - blood test - urinalysis - x ray - abdominal ultrasound - cardiology exam - slit-lamp exam - liver biopsy - genetic testing Alagille syndrome can be difficult to diagnose because the signs and symptoms vary and the syndrome is so rare. For a diagnosis of Alagille syndrome, three of the following symptoms typically should be present: - liver symptoms, such as jaundice, pruritus, malabsorption, and xanthomas - heart abnormalities or murmurs - skeletal abnormalities - posterior embryotoxon - facial features typical of Alagille syndrome - kidney disease - blood vessel problems A health care provider may perform a liver biopsy to diagnose Alagille syndrome; however, it is not necessary to make a diagnosis. A diagnosis can be made in a person who does not meet the clinical criteria of Alagille syndrome yet does have a gene mutation of JAG1. The health care provider may have a blood sample tested to look for the JAG1 gene mutation. The gene mutation can be identified in 94 percent of people with a diagnosis of Alagille syndrome.2 Blood test. A blood test involves drawing blood at a health care provider's office or a commercial facility and sending the sample to a lab for analysis. The blood test can show nutritional status and the presence of liver disease and kidney function. Urinalysis. Urinalysis is the testing of a urine sample. The urine sample is collected in a special container in a health care provider's office or a commercial facility and can be tested in the same location or sent to a lab for analysis. Urinalysis can show many problems of the urinary tract and other body systems. The sample may be observed for color, cloudiness, or concentration; signs of drug use; chemical composition, including glucose; the presence of protein, blood cells, or bacteria; or other signs of disease. X ray. An x ray is a picture created by using radiation and recorded on film or on a computer. The amount of radiation used is small. An x-ray technician performs the x ray at a hospital or an outpatient center, and a radiologista doctor who specializes in medical imaginginterprets the images. Anesthesia is not needed. The patient will lie on a table or stand during the x ray. The technician positions the x-ray machine over the spine area to look for "butterfly" vertebrae. The patient will hold his or her breath as the picture is taken so that the picture will not be blurry. The patient may be asked to change position for additional pictures. Abdominal ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The transducer can be moved to different angles to make it possible to examine different organs. In abdominal ultrasound, the health care provider applies a gel to the patient's abdomen and moves a handheld transducer over the skin. The gel allows the transducer to glide easily, and it improves the transmission of the signals. A specially trained technician performs the procedure in a health care provider's office, an outpatient center, or a hospital, and a radiologist interprets the images; anesthesia is not needed. The images can show an enlarged liver or rule out other conditions. Cardiology exam. A cardiologista doctor who treats people who have heart problemsperforms a cardiology exam in a health care provider's office, an outpatient center, or a hospital. During a full exam, a cardiologist may inspect the patient's physical appearance, measure pulse rate and blood pressure, observe the jugular vein, check for rapid or skipped heartbeats, listen for variations in heart sounds, and listen to the lungs. Slit-lamp exam. An ophthalmologista doctor who diagnoses and treats all eye diseases and eye disordersperforms a slit-lamp exam to diagnose posterior embryotoxon. The ophthalmologist examines the eye with a slit lamp, a microscope combined with a high-intensity light that shines a thin beam on the eye. While sitting in a chair, the patient will rest his or her head on the slit lamp. A yellow dye may be used to examine the cornea and tear layer. The dye is applied as a drop, or the specialist may touch a strip of paper stained with the dye to the white of the patient's eye. The specialist will also use drops in the patient's eye to dilate the pupil. Liver biopsy. A liver biopsy is a procedure that involves taking a piece of liver tissue for examination with a microscope for signs of damage or disease. The health care provider may ask the patient to stop taking certain medications temporarily before the liver biopsy. The patient may be asked to fast for 8 hours before the procedure. During the procedure, the patient lies on a table, right hand resting above the head. A local anesthetic is applied to the area where the biopsy needle will be inserted. If needed, sedatives and pain medication are also given. The health care provider uses a needle to take a small piece of liver tissue. The health care provider may use ultrasound, computerized tomography scans, or other imaging techniques to guide the needle. After the biopsy, the patient should lie on the right side for up to 2 hours and is monitored an additional 2 to 4 hours before being sent home. Genetic testing. The health care provider may refer a person suspected of having Alagille syndrome to a geneticista doctor who specializes in genetic disorders. For a genetic test, the geneticist takes a blood or saliva sample and analyzes the DNA for the JAG1 gene mutation. The geneticist tests for the JAG1 gene mutation first, since it is more common in Alagille syndrome than NOTCH2. Genetic testing is often done only by specialized labs. The results may not be available for several months because of the complexity of the testing. The usefulness of genetic testing for Alagille syndrome is limited by two factors: - Detection of a mutated gene cannot predict the onset of symptoms or how serious the disorder will be. - Even if a mutated gene is found, no specific cure for the disorder exists. When to Consider Genetic Counseling People who are considering genetic testing may want to consult a genetics counselor. Genetic counseling can help family members understand how test results may affect them individually and as a family. Genetic counseling is provided by genetics professionalshealth care professionals with specialized degrees and experience in medical genetics and counseling. Genetics professionals include geneticists, genetics counselors, and genetics nurses. Genetics professionals work as members of health care teams, providing information and support to individuals or families who have genetic disorders or a higher chance of having an inherited condition. Genetics professionals - assess the likelihood of a genetic disorder by researching a family's history, evaluating medical records, and conducting a physical exam of the patient and other family members - weigh the medical, social, and ethical decisions surrounding genetic testing - provide support and information to help a person make a decision about testing - interpret the results of genetic tests and medical data - provide counseling or refer individuals and families to support services - serve as patient advocates - explain possible treatments or preventive measures - discuss reproductive options Genetic counseling may be useful when a family member is deciding whether to have genetic testing and again later when test results are available.

### Question: What is (are) Childhood Extracranial Germ Cell Tumors ? ### Response:

Key Points - Childhood extracranial germ cell tumors form from germ cells in parts of the body other than the brain. - Childhood extracranial germ cell tumors may be benign or malignant. - There are three types of extracranial germ cell tumors. - Mature Teratomas - Immature Teratomas - Malignant Germ Cell Tumors - Childhood extracranial germ cell tumors are grouped as gonadal or extragonadal. - Gonadal Germ Cell Tumors - Extragonadal Extracranial Germ Cell Tumors - The cause of most childhood extracranial germ cell tumors is unknown. - Having certain inherited disorders can increase the risk of an extracranial germ cell tumor. - Signs of childhood extracranial germ cell tumors depend on the type of tumor and where it is in the body. - Imaging studies and blood tests are used to detect (find) and diagnose childhood extracranial germ cell tumors. - Certain factors affect prognosis (chance of recovery) and treatment options. Childhood extracranial germ cell tumors form from germ cells in parts of the body other than the brain. A germ cell is a type of cell that forms as a fetus (unborn baby) develops. These cells later become sperm in the testicles or eggs in the ovaries. Sometimes while the fetus is forming, germ cells travel to parts of the body where they should not be and grow into a germ cell tumor. The tumor may form before or after birth. This summary is about germ cell tumors that form in parts of the body that are extracranial (outside the brain). Extracranial germ cell tumors usually form in the following areas of the body: - Testicles. - Ovaries. - Sacrum or coccyx (bottom part of the spine). - Retroperitoneum (the back wall of the abdomen). - Mediastinum (area between the lungs). Extracranial germ cell tumors are most common in adolescents 15 to 19 years of age. See the PDQ summary on Childhood Central Nervous System Germ Cell Tumors Treatment for information on intracranial (inside the brain) germ cell tumors. Childhood extracranial germ cell tumors may be benign or malignant. Extracranial germ cell tumors may be benign (noncancer) or malignant (cancer). There are three types of extracranial germ cell tumors. Extracranial germ cell tumors are grouped into mature teratomas, immature teratomas, and malignant germ cell tumors: Mature Teratomas Mature teratomas are the most common type of extracranial germ cell tumor. Mature teratomas are benign tumors and not likely to become cancer. They usually occur in the sacrum or coccyx (bottom part of the spine) in newborns or in the ovaries of girls at the start of puberty. The cells of mature teratomas look almost like normal cells under a microscope. Some mature teratomas release enzymes or hormones that cause signs and symptoms of disease. Immature Teratomas Immature teratomas also usually occur in the sacrum or coccyx (bottom part of the spine) in newborns or the ovaries of girls at the start of puberty. Immature teratomas have cells that look very different from normal cells under a microscope. Immature teratomas may be cancer. They often have several different types of tissue in them, such as hair, muscle, and bone. Some immature teratomas release enzymes or hormones that cause signs and symptoms of disease. Malignant Germ Cell Tumors Malignant germ cell tumors are cancer. There are two main types of malignant germ cell tumors: - Germinomas: Tumors that make a hormone called beta-human chorionic gonadotropin (-hCG). There are three types of germinomas. - Dysgerminomas form in the ovary in girls. - Seminomas form in the testicle in boys. - Germinomas form in areas of the body that are not the ovary or testicle. - Nongerminomas: There are four types of nongerminomas. - Yolk sac tumors make a hormone called alpha-fetoprotein (AFP). They can form in the ovary, testicle, or other areas of the body. - Choriocarcinomas make a hormone called beta-human chorionic gonadotropin (-hCG). They can form in the ovary, testicle, or other areas of the body. - Embryonal carcinomas may make a hormone called -hCG and/or a hormone called AFP. They can form in the testicle or other parts of the body, but not in the ovary. - Mixed germ cell tumors are made up of both malignant germ cell tumor and teratoma. They can form in the ovary, testicle, or other areas of the body. Childhood extracranial germ cell tumors are grouped as gonadal or extragonadal. Malignant extracranial germ cell tumors are gonadal or extragonadal. Gonadal Germ Cell Tumors Gonadal germ cell tumors form in the testicles in boys or ovaries in girls. Testicular Germ Cell Tumors Testicular germ cell tumors are divided into two main types, seminoma and nonseminoma. - Seminomas make a hormone called beta-human chorionic gonadotropin (-hCG). - Nonseminomas are usually large and cause signs or symptoms. They tend to grow and spread more quickly than seminomas. Testicular germ cell tumors usually occur before the age of 4 years or in adolescents and young adults. Testicular germ cell tumors in adolescents and young adults are different from those that form in early childhood. Boys older than 14 years with testicular germ cell tumors are treated in pediatric cancer centers, but the treatment is much like the treatment used in adults. (See the PDQ summary on Testicular Cancer Treatment for more information.) Ovarian Germ Cell Tumors Ovarian germ cell tumors are more common in adolescent girls and young women. Most ovarian germ cell tumors are benign teratomas. Sometimes immature teratomas, dysgerminomas, yolk sac tumors, and mixed germ cell tumors (cancer) occur. (See the PDQ summary on Ovarian Germ Cell Tumors Treatment for more information.) Extragonadal Extracranial Germ Cell Tumors Extragonadal extracranial germ cell tumors form in areas other than the brain, testicles, or ovaries. Most extragonadal extracranial germ cell tumors form along the midline of the body. This includes the following: - Sacrum (the large, triangle-shaped bone in the lower spine that forms part of the pelvis). - Coccyx (the small bone at the bottom of the spine, also called the tailbone). - Mediastinum (the area between the lungs). - Back of the abdomen. - Neck. In younger children, extragonadal extracranial germ cell tumors usually occur at birth or in early childhood. Most of these tumors are teratomas in the sacrum or coccyx. In older children, adolescents, and young adults, extragonadal extracranial germ cell tumors are often in the mediastinum.

### Question: Who is at risk for Breast Cancer? ? ### Response:

What Is Cancer Prevention? Cancer prevention is action taken to lower the chance of getting cancer. By preventing cancer, the number of new cases of cancer in a group or population is lowered. Hopefully, this will lower the number of deaths caused by cancer. When studying ways to prevent cancer, scientists look at risk factors and protective factors. Anything that increases your chance of developing cancer is called a cancer risk factor. Anything that decreases your chance of developing cancer is called a cancer protective factor. Risk Factors Some risk factors for cancer can be avoided, but many cannot. For example, both smoking and inheriting certain genes are risk factors for some types of cancer, but only smoking can be avoided. Regular exercise and a healthy diet may be protective factors for some types of cancer. Avoiding risk factors and increasing protective factors may lower your risk but it does not mean that you will not get cancer. Different ways to prevent cancer are being studied, including - changing lifestyle or eating habits - avoiding things known to cause cancer - taking medicine to treat a precancerous condition or to keep cancer from starting. changing lifestyle or eating habits avoiding things known to cause cancer taking medicine to treat a precancerous condition or to keep cancer from starting. (For more on risk factors, see the chapter on "Risk Factors.") Here are protective factors for breast cancer. Less Exposure to Estrogen Decreasing the length of time a woman's breast tissue is exposed to estrogen may help lower her risk of developing breast cancer. Exposure to estrogen is reduced in the following ways. - Early pregnancy. Estrogen levels are lower during pregnancy. Women who have a full-term pregnancy before age 20 have a lower risk of breast cancer than women who have not had children or who give birth to their first child after age 35. - Breast-feeding. Estrogen levels may remain lower while a woman is breast-feeding. Women who breastfed have a lower risk of breast cancer than women who have had children but did not breastfeed. - Surgical removal of the ovaries. The ovaries make estrogen. The amount of estrogen made by the body can be greatly reduced by removing one or both ovaries. Also, drugs may be taken to lower the amount of estrogen made by the ovaries. - Late menstruation. Menstrual periods that start at age 14 or older decreases the number of years the breast tissue is exposed to estrogen. - Early menopause. The fewer years a woman menstruates, the shorter the time her breast tissue is exposed to estrogen. Early pregnancy. Estrogen levels are lower during pregnancy.

The fewer years a woman menstruates, the shorter the time her breast tissue is exposed to estrogen. Exercise Women who exercise four or more hours a week have a lower risk of breast cancer. The effect of exercise on breast cancer risk may be greatest in premenopausal women who have normal or low body weight. Learn more about the benefits of exercise for older adults. For exercises tailored to older adults, visit Go4Life, the exercise and physical activity campaign from the National Institute on Aging (NIA) at NIH. Estrogen-only Hormone Therapy After Hysterectomy Hormone therapy with estrogen only may be given to women who have had a hysterectomy. In these women, estrogen-only therapy after menopause may decrease the risk of breast cancer. There is an increased risk of stroke and heart and blood vessel disease in postmenopausal women who take estrogen after a hysterectomy. Learn about menopausal hormone therapy and cancer. Selective Estrogen Receptor Modulators (SERMs) Tamoxifen and raloxifene belong to the family of drugs called selective estrogen receptor modulators (SERMs). SERMs act like estrogen on some tissues in the body, but block the effect of estrogen on other tissues. Treatment with tamoxifen or raloxifene lowers the risk of breast cancer in postmenopausal women. Tamoxifen also lowers the risk of breast cancer in high-risk premenopausal women. With either drug, the reduced risk lasts for several years after treatment is stopped. Lower rates of broken bones have been noted in patients taking raloxifene. Prophylactic Mastectomy Some women who have a high risk of breast cancer may choose to have a prophylactic mastectomy (the removal of both breasts when there are no signs of cancer). The risk of breast cancer is much lower in these women and most feel less anxious about their risk of breast cancer. However, it is very important to have cancer risk assessment and counseling about the different ways to prevent breast cancer before making this decision. Learn more about surgery to reduce the risk of breast cancer. Prophylactic Oophorectomy Premenopausal women who have a high risk of breast cancer due to certain changes in the BRCA1 and BRCA2 genes may choose to have a prophylactic oophorectomy (the removal of both ovaries when there are no signs of cancer). This decreases the amount of estrogen made by the body and lowers the risk of breast cancer. Prophylactic oophorectomy also lowers the risk of breast cancer in normal premenopausal women and in women with an increased risk of breast cancer due to radiation to the chest. However, it is very important to have cancer risk assessment and counseling before making this decision. The sudden drop in estrogen levels may cause the symptoms of menopause to begin. These include hot flashes, trouble sleeping, anxiety, and depression. Long-term effects include decreased sex drive, vaginal dryness, and decreased bone density. Unclear As Risk Factors It is not clear whether the following affect the risk of breast cancer. - Oral contraceptives. Taking oral contraceptives ("the pill") may slightly increase the risk of breast cancer in current users. This risk decreases over time. Some oral contraceptives contain estrogen. Progestin-only contraceptives that are injected or implanted do not appear to increase the risk of breast cancer. - Environment. Studies have not proven that being exposed to certain substances in the environment, such as chemicals, increases the risk of breast cancer. Oral contraceptives.

### Question: What are the stages of Merkel Cell Carcinoma ? ### Response:

Key Points - After Merkel cell carcinoma has been diagnosed, tests are done to find out if cancer cells have spread 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 Merkel cell carcinoma: - Stage 0 (carcinoma in situ) - Stage IA - Stage IB - Stage IIA - Stage IIB - Stage IIC - Stage IIIA - Stage IIIB - Stage IV After Merkel cell carcinoma has been diagnosed, tests are done to find out if cancer cells have spread to other parts of the body. The process used to find out if cancer has spread 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 following tests and procedures may be used in the staging process: - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. A CT scan of the chest and abdomen may be used to check for primary small cell lung cancer, or to find Merkel cell carcinoma that has spread. A CT scan of the head and neck may also be used to find Merkel cell carcinoma that has spread to the lymph nodes. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - Lymph node biopsy : There are two main types of lymph node biopsy used to stage Merkel cell carcinoma. - Sentinel lymph node biopsy : The removal of the sentinel lymph node during surgery. The sentinel lymph node is the first lymph node to receive lymphatic drainage from a tumor. It is the first lymph node the cancer is likely to spread to from the tumor. A radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through the lymph ducts to the lymph nodes. The first lymph node to receive the substance or dye is removed. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are not found, it may not be necessary to remove more lymph nodes. - Lymph node dissection : A surgical procedure in which the lymph nodes are removed and a sample of tissue is checked under a microscope for signs of cancer. For a regional lymph node dissection, some of the lymph nodes in the tumor area are removed. For a radical lymph node dissection, most or all of the lymph nodes in the tumor area are removed. This procedure is also called lymphadenectomy. - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. 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 Merkel cell carcinoma spreads to the liver, the cancer cells in the liver are actually cancerous Merkel cells. The disease is metastatic Merkel cell carcinoma, not liver cancer. The following stages are used for Merkel cell carcinoma: Stage 0 (carcinoma in situ) In stage 0, the tumor is a group of abnormal cells that remain in the place where they first formed and have not spread. These abnormal cells may become cancer and spread to lymph nodes or distant parts of the body. Stage IA In stage IA, the tumor is 2 centimeters or smaller at its widest point and no cancer is found when the lymph nodes are checked under a microscope. Stage IB In stage IB, the tumor is 2 centimeters or smaller at its widest point and no swollen lymph nodes are found by a physical exam or imaging tests. Stage IIA In stage IIA, the tumor is larger than 2 centimeters and no cancer is found when the lymph nodes are checked under a microscope. Stage IIB In stage IIB, the tumor is larger than 2 centimeters and no swollen lymph nodes are found by a physical exam or imaging tests. Stage IIC In stage IIC, the tumor may be any size and has spread to nearby bone, muscle, connective tissue, or cartilage. It has not spread to lymph nodes or distant parts of the body. Stage IIIA In stage IIIA, the tumor may be any size and may have spread to nearby bone, muscle, connective tissue, or cartilage. Cancer is found in the lymph nodes when they are checked under a microscope. Stage IIIB In stage IIIB, the tumor may be any size and may have spread to nearby bone, muscle, connective tissue, or cartilage. Cancer has spread to the lymph nodes near the tumor and is found by a physical exam or imaging test. The lymph nodes are removed and cancer is found in the lymph nodes when they are checked under a microscope. There may also be a second tumor, which is either: - Between the primary tumor and nearby lymph nodes; or - Farther away from the center of the body than the primary tumor is. Stage IV In stage IV, the tumor may be any size and has spread to distant parts of the body, such as the liver, lung, bone, or brain.

### Question: What are the symptoms of High Blood Pressure ? ### Response:

High blood pressure is often called the "silent killer" because you can have it for years without knowing it. The only way to find out if you have high blood pressure is to have your blood pressure measured. Complications When blood pressure stays high over time, it can damage the body and cause complications. Here are some of the common complications, along with their signs and symptoms. - Aneurysms. These occur when an abnormal bulge forms in the wall of an artery. Aneurysms develop and grow for years without causing signs or symptoms until they rupture, grow large enough to press on nearby body parts, or block blood flow. The signs and symptoms that develop depend on the location of the aneurysm. - Chronic Kidney Disease. This disease occurs when blood vessels narrow in the kidneys, possibly causing kidney failure. - Cognitive Changes Research shows that over time, higher blood pressure numbers can lead to cognitive changes. Signs and symptoms include memory loss, difficulty finding words, and losing focus during conversations. - Eye Damage. This condition occurs when blood vessels in the eyes burst or bleed. Signs and symptoms include vision changes or blindness. - Heart Attack. This occurs when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart doesnt get oxygen. The most common warning symptoms of a heart attack are chest pain or discomfort, upper body discomfort, and shortness of breath. - Heart Failure. This condition occurs when the heart cant pump enough blood to meet the bodys needs. Common signs and symptoms of heart failure include shortness of breath or trouble breathing; feeling tired; and swelling in the ankles, feet, legs, abdomen, and veins in the neck. - Peripheral Arterial Disease. This is a disease in which plaque builds up in leg arteries and affects blood flow in the legs. When people have symptoms, the most common are pain, cramping, numbness, aching, or heaviness in the legs, feet, and buttocks after walking or climbing stairs. - Stroke. A stroke occurs when the flow of oxygen-rich blood to a portion of the brain is blocked. The symptoms of a stroke include sudden onset of weakness; paralysis or numbness of the face, arms, or legs; trouble speaking or understanding speech; and trouble seeing. Aneurysms.

The symptoms of a stroke include sudden onset of weakness; paralysis or numbness of the face, arms, or legs; trouble speaking or understanding speech; and trouble seeing. How Blood Pressure Is Checked Your health care provider usually takes 23 readings at several medical appointments to diagnose high blood pressure. Based on the results of your blood pressure test, your health care provider will diagnose prehypertension or high blood pressure if your systolic or diastolic readings are consistently higher than 120/80 mmHg. Once your health care provider determines the severity of your blood pressure, he or she can order additional tests to determine if your blood pressure is due to other conditions or medicines or if you have primary high blood pressure. Health care providers can use this information to develop your treatment plan. Some people have white coat hypertension. This happens when blood pressure readings are only high when taken in a health care providers office compared with readings taken in any other location. Researchers believe stress, which can occur during the medical appointment, causes white coat hypertension. Preparing for the Test A blood pressure test is easy and painless and can be done in a health care providers office or clinic. To prepare for the test - dont drink coffee or smoke cigarettes for 30 minutes prior to the test - go to the bathroom before the test. A full bladder can change the reading - sit for 5 minutes before the test. dont drink coffee or smoke cigarettes for 30 minutes prior to the test go to the bathroom before the test. A full bladder can change the reading sit for 5 minutes before the test. To track blood pressure readings over a period of time, the health care provider may ask you to come into the office on different days and at different times to take your blood pressure. The health care provider also may ask you to check readings at home or at other locations that have blood pressure equipment and to keep a written log of all your results. Whenever you have an appointment with the health care provider, be sure to bring your log of blood pressure readings. Ask the doctor or nurse to tell you your blood pressure reading in numbers and to explain what the numbers mean. Write down your numbers or ask the doctor or nurse to write them down for you. Write Down Your Readings Ask the doctor or nurse to tell you your blood pressure reading in numbers and to explain what the numbers mean. Write down your numbers or ask the doctor or nurse to write them down for you. (The wallet card on the right can be printed out and used to record your blood pressure numbers.) Checking Your Own Blood Pressure You can also check your blood pressure at home with a home blood pressure measurement device or monitor. It is important that the blood pressure cuff fits you properly and that you understand how to use the monitor. A cuff that is too small, for example, can give you a reading that is higher than your actual blood pressure. Your doctor, nurse, or pharmacist can help you check the cuff size and teach you how to use it correctly. You may also ask for their help in choosing the right blood pressure monitor for you. Blood pressure monitors can be bought at discount chain stores and drug stores. When you are taking your blood pressure at home, sit with your back supported and your feet flat on the floor. Rest your arm on a table at the level of your heart. After a Diagnosis If you're diagnosed with high blood pressure, your doctor will prescribe treatment. Your blood pressure will be tested again to see how the treatment affects it. Once your blood pressure is under control, you'll still need treatment. "Under control" means that your blood pressure numbers are in the normal range. Your doctor will likely recommend routine blood pressure tests. He or she can tell you how often you should be tested. The sooner you find out about high blood pressure and treat it, the better. Early treatment may help you avoid problems such as heart attack, stroke and kidney failure. See tips for talking with your doctor after you receive a medical diagnosis.

### Question: How to diagnose Cardiomyopathy ? ### Response:

Your doctor will diagnose cardiomyopathy based on your medical and family histories, a physical exam, and the results from tests and procedures. Specialists Involved Often, a cardiologist or pediatric cardiologist diagnoses and treats cardiomyopathy. A cardiologist specializes in diagnosing and treating heart diseases. A pediatric cardiologist is a cardiologist who treats children. Medical and Family Histories Your doctor will want to learn about your medical history. He or she will want to know what signs and symptoms you have and how long you've had them. Your doctor also will want to know whether anyone in your family has had cardiomyopathy, heart failure, or sudden cardiac arrest. Physical Exam Your doctor will use a stethoscope to listen to your heart and lungs for sounds that may suggest cardiomyopathy. These sounds may even suggest a certain type of the disease. For example, the loudness, timing, and location of a heart murmur may suggest obstructive hypertrophic cardiomyopathy. A "crackling" sound in the lungs may be a sign of heart failure. (Heart failure often develops in the later stages of cardiomyopathy.) Physical signs also help your doctor diagnose cardiomyopathy. Swelling of the ankles, feet, legs, abdomen, or veins in your neck suggests fluid buildup, a sign of heart failure. Your doctor may notice signs and symptoms of cardiomyopathy during a routine exam. For example, he or she may hear a heart murmur, or you may have abnormal test results. Diagnostic Tests Your doctor may recommend one or more of the following tests to diagnose cardiomyopathy. Blood Tests During a blood test, a small amount of blood is taken from your body. It's often drawn from a vein in your arm using a needle. The procedure usually is quick and easy, although it may cause some short-term discomfort. Blood tests give your doctor information about your heart and help rule out other conditions. Chest X Ray A chest x ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. This test can show whether your heart is enlarged. A chest x ray also can show whether fluid is building up in your lungs. EKG (Electrocardiogram) An EKG is a simple test that records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through each part of the heart. This test is used to detect and study many heart problems, such as heart attacks, arrhythmias (irregular heartbeats), and heart failure. EKG results also can suggest other disorders that affect heart function. A standard EKG only records the heartbeat for a few seconds. It won't detect problems that don't happen during the test. To diagnose heart problems that come and go, your doctor may have you wear a portable EKG monitor. The two most common types of portable EKGs are Holter and event monitors. Holter and Event Monitors Holter and event monitors are small, portable devices. They record your heart's electrical activity while you do your normal daily activities. A Holter monitor records the heart's electrical activity for a full 24- or 48-hour period. An event monitor records your heart's electrical activity only at certain times while you're wearing it. For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms. Echocardiography Echocardiography (echo) is a test that uses sound waves to create a moving picture of your heart. The picture shows how well your heart is working and its size and shape. There are several types of echo, including stress echo. This test is done as part of a stress test (see below). Stress echo can show whether you have decreased blood flow to your heart, a sign of coronary heart disease. Another type of echo is transesophageal (tranz-ih-sof-uh-JEE-ul) echo, or TEE. TEE provides a view of the back of the heart. For this test, a sound wave wand is put on the end of a special tube. The tube is gently passed down your throat and into your esophagus (the passage leading from your mouth to your stomach). Because this passage is right behind the heart, TEE can create detailed pictures of the heart's structures. Before TEE, you're given medicine to help you relax, and your throat is sprayed with numbing medicine. Stress Test Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise (or are given medicine if you're unable to exercise) to make your heart work hard and beat fast while heart tests are done. These tests may include nuclear heart scanning, echo, and positron emission tomography (PET) scanning of the heart. Diagnostic Procedures You may have one or more medical procedures to confirm a diagnosis or to prepare for surgery (if surgery is planned). These procedures may include cardiac catheterization (KATH-e-ter-i-ZA-shun), coronary angiography (an-jee-OG-ra-fee), or myocardial (mi-o-KAR-de-al) biopsy. Cardiac Catheterization This procedure checks the pressure and blood flow in your heart's chambers. The procedure also allows your doctor to collect blood samples and look at your heart's arteries using x-ray imaging. During cardiac catheterization, a long, thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck and threaded to your heart. This allows your doctor to study the inside of your arteries for blockages. Coronary Angiography This procedure often is done with cardiac catheterization. During the procedure, dye that can be seen on an x ray is injected into your coronary arteries. The dye lets your doctor study blood flow through your heart and blood vessels. Dye also may be injected into your heart chambers. This allows your doctor to study the pumping function of your heart. Myocardial Biopsy For this procedure, your doctor removes a piece of your heart muscle. This can be done during cardiac catheterization. The heart muscle is studied under a microscope to see whether changes in cells have occurred. These changes may suggest cardiomyopathy. Myocardial biopsy is useful for diagnosing some types of cardiomyopathy. Genetic Testing Some types of cardiomyopathy run in families. Thus, your doctor may suggest genetic testing to look for the disease in your parents, brothers and sisters, or other family members. Genetic testing can show how the disease runs in families. It also can find out the chances of parents passing the genes for the disease on to their children. Genetic testing also may be useful if your doctor thinks you have cardiomyopathy, but you don't yet have signs or symptoms. If the test shows you have the disease, your doctor can start treatment early, when it may work best.

### Question: What is (are) Wilms Tumor and Other Childhood Kidney Tumors ? ### Response:

Key Points - Childhood kidney tumors are diseases in which malignant (cancer) cells form in the tissues of the kidney. - There are many types of childhood kidney tumors. - Wilms Tumor - Renal Cell Cancer (RCC) - Rhabdoid Tumor of the Kidney - Clear Cell Sarcoma of the Kidney - Congenital Mesoblastic Nephroma - Ewing Sarcoma of the Kidney - Primary Renal Myoepithelial Carcinoma - Cystic Partially Differentiated Nephroblastoma - Multilocular Cystic Nephroma - Primary Renal Synovial Sarcoma - Anaplastic Sarcoma of the Kidney - Nephroblastomatosis is not cancer but may become Wilms tumor. - Having certain genetic syndromes or other conditions can increase the risk of Wilms tumor. - Tests are used to screen for Wilms tumor. - Having certain conditions may increase the risk of renal cell cancer. - Treatment for Wilms tumor and other childhood kidney tumors may include genetic counseling. - Signs of Wilms tumor and other childhood kidney tumors include a lump in the abdomen and blood in the urine. - Tests that examine the kidney and the blood are used to detect (find) and diagnose Wilms tumor and other childhood kidney tumors. - Certain factors affect prognosis (chance of recovery) and treatment options. Childhood kidney tumors are diseases in which malignant (cancer) cells form in the tissues of the kidney. There are two kidneys, one on each side of the backbone, above the waist. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine passes from each kidney through a long tube called a ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body. There are many types of childhood kidney tumors. Wilms Tumor In Wilms tumor, one or more tumors may be found in one or both kidneys. Wilms tumor may spread to the lungs, liver, bone, brain, or nearby lymph nodes. In children and adolescents younger than 15 years old, most kidney cancers are Wilms tumors. Renal Cell Cancer (RCC) Renal cell cancer is rare in children and adolescents younger than 15 years old. It is much more common in adolescents between 15 and 19 years old. Children and adolescents are more likely to be diagnosed with a large renal cell tumor or cancer that has spread. Renal cell cancers may spread to the lungs, liver, or lymph nodes. Renal cell cancer may also be called renal cell carcinoma. Rhabdoid Tumor of the Kidney Rhabdoid tumor of the kidney is a type of kidney cancer that occurs mostly in infants and young children. It is often advanced at the time of diagnosis. Rhabdoid tumor of the kidney grows and spreads quickly, often to the lungs or brain. Children with a certain change in the SMARCB1 gene are checked regularly to see if a rhabdoid tumor has formed in the kidney or has spread to the brain: - Children younger than one year old have an ultrasound of the abdomen every two to three months and an ultrasound of the head every month. - Children one to four years old have an ultrasound of the abdomen and an MRI of the brain and spine every three months. Clear Cell Sarcoma of the Kidney Clear cell sarcoma of the kidney is a type of kidney tumor that may spread to the lung, bone, brain, or soft tissue. When it recurs (comes back) after treatment, it often recurs in the brain or lung. Congenital Mesoblastic Nephroma Congenital mesoblastic nephroma is a tumor of the kidney that is often diagnosed during the first year of life. It can usually be cured. Ewing Sarcoma of the Kidney Ewing sarcoma (previously called neuroepithelial tumor) of the kidney is rare and usually occurs in young adults. These tumors grow and spread to other parts of the body quickly. Primary Renal Myoepithelial Carcinoma Primary renal myoepithelial carcinoma is a rare type of cancer that usually affects soft tissues, but sometimes forms in the internal organs (such as the kidney). This type of cancer grows and spreads quickly. Cystic Partially Differentiated Nephroblastoma Cystic partially differentiated nephroblastoma is a very rare type of Wilms tumor made up of cysts. Multilocular Cystic Nephroma Multilocular cystic nephromas are benign tumors made up of cysts and are most common in infants, young children, and adult women. These tumors can occur in one or both kidneys. Children with this type of tumor also may have pleuropulmonary blastoma, so imaging tests that check the lungs for cysts or solid tumors are done. Since multilocular cystic nephroma may be an inherited condition, genetic counseling and genetic testing may be considered. See the PDQ summary about Unusual Cancers of Childhood Treatment for more information about pleuropulmonary blastoma. Primary Renal Synovial Sarcoma Primary renal synovial sarcoma is a cyst-like tumor of the kidney and is most common in young adults. These tumors grow and spread quickly. Anaplastic Sarcoma of the Kidney Anaplastic sarcoma of the kidney is a rare tumor that is most common in children or adolescents younger than 15 years of age. Anaplastic sarcoma of the kidney often spreads to the lungs, liver, or bones. Imaging tests that check the lungs for cysts or solid tumors may be done. Since anaplastic sarcoma may be an inherited condition, genetic counseling and genetic testing may be considered. Nephroblastomatosis is not cancer but may become Wilms tumor. Sometimes, after the kidneys form in the fetus, abnormal groups of kidney cells remain in one or both kidneys. In nephroblastomatosis (diffuse hyperplastic perilobar nephroblastomatosis), these abnormal groups of cells may grow in many places inside the kidney or make a thick layer around the kidney. When these groups of abnormal cells are found in a kidney after it was removed for Wilms tumor, the child has an increased risk of Wilms tumor in the other kidney. Frequent follow-up testing is important at least every 3 months, for at least 7 years after the child is treated. Treatment for Wilms tumor and other childhood kidney tumors may include genetic counseling. Genetic counseling (a discussion with a trained professional about genetic diseases and whether genetic testing is needed) may be needed if the child has one of the following syndromes or conditions: - A genetic syndrome or condition that increases the risk of Wilms tumor. - An inherited condition that increases the risk of renal cell cancer. - Rhabdoid tumor of the kidney. - Multilocular cystic nephroma.

### Question: What are the stages of Ovarian Germ Cell Tumors ? ### Response:

Key Points - After ovarian germ cell tumor has been diagnosed, tests are done to find out if cancer cells have spread within the ovary 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 germ cell tumors: - Stage I - Stage II - Stage III - Stage IV After ovarian germ cell tumor has been diagnosed, tests are done to find out if cancer cells have spread within the ovary or to other parts of the body. The process used to find out whether cancer has spread within the ovary or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. Unless a doctor is sure the cancer has spread from the ovaries to other parts of the body, an operation called a laparotomy is done to see if the cancer has spread. The doctor must cut into the abdomen and carefully look at all the organs to see if they have cancer in them. The doctor will cut out small pieces of tissue so they can be checked under a microscope for signs of cancer. The doctor may also wash the abdominal cavity with fluid, which is also checked under a microscope to see if it has cancer cells in it. Usually the doctor will remove the cancer and other organs that have cancer in them during the laparotomy. It is important to know the stage in order to plan treatment. Many of the tests used to diagnose ovarian germ cell tumor are also used for staging. The following tests and procedures may also be used for staging: - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Transvaginal ultrasound exam: A procedure used to examine the vagina, uterus, fallopian tubes, and bladder. An ultrasound transducer (probe) is inserted into the vagina and used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The doctor can identify tumors by looking at the sonogram. 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 tumor as the primary tumor. For example, if an ovarian germ cell tumor spreads to the liver, the tumor cells in the liver are actually cancerous ovarian germ cells. The disease is metastatic ovarian germ cell tumor, not liver cancer. The following stages are used for ovarian germ cell tumors: Stage I In stage I, cancer is found in one or both ovaries. Stage I is divided into stage IA, stage IB, and stage IC. - Stage IA: Cancer is found inside a single ovary. - Stage IB: Cancer is found inside both ovaries. - Stage IC: Cancer is found inside one or both ovaries and one of the following is true: - cancer is also found on the outside surface of one or both ovaries; or - the capsule (outer covering) of the ovary has ruptured (broken open); 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 and has spread into other areas of the pelvis. Stage II is divided into stage IIA, stage IIB, and stage IIC. - Stage IIA: Cancer has spread to the uterus and/or fallopian tubes (the long slender tubes through which eggs pass from the ovaries to the uterus). - Stage IIB: Cancer has spread to other tissue within the pelvis. - Stage IIC: Cancer is found inside one or both ovaries and has spread to the uterus and/or fallopian tubes, or to other tissue within the pelvis. Also, one of the following is true: - cancer is found on the outside surface of one or both ovaries; or - the capsule (outer covering) of the ovary has ruptured (broken open); 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 III In stage III, cancer is found in one or both ovaries and has spread outside the pelvis to other parts of the abdomen and/or nearby lymph nodes. Stage III is divided into stage IIIA, stage IIIB, and stage IIIC. - Stage IIIA: The tumor is found in the pelvis only, but cancer cells that can be seen only with a microscope have spread to the surface of the peritoneum (tissue that lines the abdominal wall and covers most of the organs in the abdomen), the small intestines, or the tissue that connects the small intestines to the wall of the abdomen. - Stage IIIB: Cancer has spread to the peritoneum and the cancer in the peritoneum is 2 centimeters or smaller. - Stage IIIC: Cancer has spread to the peritoneum and the cancer in the peritoneum is larger than 2 centimeters and/or cancer has spread to lymph nodes in the abdomen. Cancer that has spread to the surface of the liver is also considered stage III ovarian cancer. Stage IV In stage IV, cancer has spread beyond the abdomen to other parts of the body, such as the lungs or tissue inside the liver. Cancer cells in the fluid around the lungs is also considered stage IV ovarian cancer.

### Question: What are the symptoms of Osteoarthritis ? ### Response:

Pain and Stiffness in Joints Different types of arthritis have different symptoms. In general, people with most forms of arthritis have pain and stiffness in their joints. Osteoarthritis usually develops slowly and can occur in any joint, but often occurs in weight-bearing joints. Early in the disease, joints may ache after physical work or exercise. Most often, osteoarthritis occurs in the hands, hips, knees, neck, or low back. Common Signs Common signs of osteoarthritis include - joint pain, swelling, and tenderness - stiffness after getting out of bed - a crunching feeling or sound of bone rubbing on bone. joint pain, swelling, and tenderness stiffness after getting out of bed a crunching feeling or sound of bone rubbing on bone. Not everyone with osteoarthritis feels pain, however. In fact, only a third of people with x-ray evidence of osteoarthritis report pain or other symptoms. Diagnosis To make a diagnosis of osteoarthritis, most doctors use a combination of methods and tests including a medical history, a physical examination, x-rays, and laboratory tests. - A medical history is the patient's description of symptoms and when and how they began. The description covers pain, stiffness, and joint function, and how these have changed over time. - A physical examination includes the doctor's examination of the joints, skin, reflexes, and muscle strength. The doctor observes the patient's ability to walk, bend, and carry out activities of daily living. - X-rays are limited in their capacity to reveal how much joint damage may have occurred in osteoarthritis. X-rays usually don't show osteoarthritis damage until there has been a significant loss of cartilage. A medical history is the patient's description of symptoms and when and how they began.

Questions Your Doctor May Ask It is important for people with joint pain to give the doctor a complete medical history. Answering these questions will help your doctor make an accurate diagnosis: - Is the pain in one or more joints? - When does the pain occur and how long does it last? - When did you first notice the pain? - Does activity make the pain better or worse? - Have you had any illnesses or accidents that may account for the pain? - Is there a family history of any arthritis or rheumatic diseases? - What medicines are you taking? Is the pain in one or more joints? When does the pain occur and how long does it last? When did you first notice the pain? Does activity make the pain better or worse? Have you had any illnesses or accidents that may account for the pain? Is there a family history of any arthritis or rheumatic diseases? What medicines are you taking? A patient's attitudes, daily activities, and levels of anxiety or depression have a lot to do with how severe the symptoms of osteoarthritis may be. Who Can Provide Care Treating arthritis often requires a multidisciplinary or team approach. Many types of health professionals care for people with arthritis. You may choose a few or more of the following professionals to be part of your health care team. - Primary care physicians -- doctors who treat patients before they are referred to other specialists in the health care system. Often a primary care physician will be the main doctor to treat your arthritis.

### Question: How to diagnose Hemolytic Anemia ? ### Response:

Your doctor will diagnose hemolytic anemia based on your medical and family histories, a physical exam, and test results. Specialists Involved Primary care doctors, such as a family doctor or pediatrician, may help diagnose and treat hemolytic anemia. Your primary care doctor also may refer you to a hematologist. This is a doctor who specializes in diagnosing and treating blood diseases and disorders. Doctors and clinics that specialize in treating inherited blood disorders, such as sickle cell anemia and thalassemias, also may be involved. If your hemolytic anemia is inherited, you may want to consult a genetic counselor. A counselor can help you understand your risk of having a child who has the condition. He or she also can explain the choices that are available to you. Medical and Family Histories To find the cause and severity of hemolytic anemia, your doctor may ask detailed questions about your symptoms, personal medical history, and your family medical history. He or she may ask whether: You or anyone in your family has had problems with anemia You've recently had any illnesses or medical conditions You take any medicines, and which ones You've been exposed to certain chemicals or substances You have an artificial heart valve or other medical device that could damage your red blood cells Physical Exam Your doctor will do a physical exam to check for signs of hemolytic anemia. He or she will try to find out how severe the condition is and what's causing it. The exam may include: Checking for jaundice (a yellowish color of the skin or whites of the eyes) Listening to your heart for rapid or irregular heartbeats Listening for rapid or uneven breathing Feeling your abdomen to check the size of your spleen Doing a pelvic and rectal exam to check for internal bleeding Diagnostic Tests and Procedures Many tests are used to diagnose hemolytic anemia. These tests can help confirm a diagnosis, look for a cause, and find out how severe the condition is. Complete Blood Count Often, the first test used to diagnose anemia is a complete blood count (CBC). The CBC measures many parts of your blood. This test checks your hemoglobin and hematocrit (hee-MAT-oh-crit) levels. Hemoglobin is an iron-rich protein in red blood cells that carries oxygen to the body. Hematocrit is a measure of how much space red blood cells take up in your blood. A low level of hemoglobin or hematocrit is a sign of anemia. The normal range of these levels may vary in certain racial and ethnic populations. Your doctor can explain your test results to you. The CBC also checks the number of red blood cells, white blood cells, and platelets in your blood. Abnormal results may be a sign of hemolytic anemia, a different blood disorder, an infection, or another condition. Finally, the CBC looks at mean corpuscular (kor-PUS-kyu-lar) volume (MCV). MCV is a measure of the average size of your red blood cells. The results may be a clue as to the cause of your anemia. Other Blood Tests If the CBC results confirm that you have anemia, you may need other blood tests to find out what type of anemia you have and how severe it is. Reticulocyte count. A reticulocyte (re-TIK-u-lo-site) count measures the number of young red blood cells in your blood. The test shows whether your bone marrow is making red blood cells at the correct rate. People who have hemolytic anemia usually have high reticulocyte counts because their bone marrow is working hard to replace the destroyed red blood cells. Peripheral smear. For this test, your doctor will look at your red blood cells through a microscope. Some types of hemolytic anemia change the normal shape of red blood cells. Coombs' test. This test can show whether your body is making antibodies (proteins) to destroy red blood cells. Haptoglobin, bilirubin, and liver function tests. When red blood cells break down, they release hemoglobin into the bloodstream. The hemoglobin combines with a chemical called haptoglobin. A low level of haptoglobin in the bloodstream is a sign of hemolytic anemia. Hemoglobin is broken down into a compound called bilirubin. High levels of bilirubin in the bloodstream may be a sign of hemolytic anemia. High levels of this compound also occur with some liver and gallbladder diseases. Thus, you may need liver function tests to find out what's causing the high bilirubin levels. Hemoglobin electrophoresis. This test looks at the different types of hemoglobin in your blood. It can help diagnose the type of anemia you have. Testing for paroxysmal nocturnal hemoglobinuria (PNH). In PNH, the red blood cells are missing certain proteins. The test for PNH can detect red blood cells that are missing these proteins. Osmotic fragility test. This test looks for red blood cells that are more fragile than normal. These cells may be a sign of hereditary spherocytosis (an inherited type of hemolytic anemia). Testing for glucose-6-phosphate dehydrogenase (G6PD) deficiency. In G6PD deficiency, the red blood cells are missing an important enzyme called G6PD. The test for G6PD deficiency looks for this enzyme in a sample of blood. Urine Test A urine test will look for the presence of free hemoglobin (a protein that carries oxygen in the blood) and iron. Bone Marrow Tests Bone marrow tests show whether your bone marrow is healthy and making enough blood cells. The two bone marrow tests are aspiration (as-pi-RA-shun) and biopsy. For a bone marrow aspiration, your doctor removes a small amount of fluid bone marrow through a needle. The sample is examined under a microscope to check for faulty cells. A bone marrow biopsy may be done at the same time as an aspiration or afterward. For this test, your doctor removes a small amount of bone marrow tissue through a needle. The tissue is examined to check the number and type of cells in the bone marrow. You may not need bone marrow tests if blood tests show what's causing your hemolytic anemia. Tests for Other Causes of Anemia Because anemia has many causes, you may have tests for conditions such as: Kidney failure Lead poisoning Vitamin or iron deficiency Newborn Testing for Sickle Cell Anemia and G6PD Deficiency All States mandate screening for sickle cell anemia as part of their newborn screening programs. Some States also mandate screening for G6PD deficiency. These inherited types of hemolytic anemia can be detected with routine blood tests. Diagnosing these conditions as early as possible is important so that children can get proper treatment.

### Question: Who is at risk for Breast Cancer? ? ### Response:

Some women develop breast cancer and others do not, and the risk factors for the disease vary. Breast cancer may affect younger women, but three-fourths of all breast cancers occur in women between the ages of 45 to 85. In Situ and Invasive Breast Cancer Researchers often talk about breast cancer in two ways: in situ and invasive. In situ refers to cancer that has not spread beyond its site of origin. Invasive applies to cancer that has spread to the tissue around it. This chart shows what the approximate chances are of a woman getting invasive breast cancer in her lifetime. Risk Factors Risk factors are conditions or agents that increase a person's chances of getting a disease. Here are the most common risk factors for breast cancer. - Older age. The risk of breast cancer in a 70 year old woman is about 10 times that of a 30 year old woman, but risk decreases after age 85. Older age. The risk of breast cancer in a 70 year old woman is about 10 times that of a 30 year old woman, but risk decreases after age 85. - Personal and family history. A personal history of breast cancer or breast cancer among one or more of your close relatives, such as a sister, mother, or daughter. Personal and family history.

However, black women diagnosed with breast cancer are more likely to die of the disease. - Inherited gene changes. Women who have inherited certain changes in the genes named BRCA1 and BRCA2 have a higher risk of breast cancer, ovarian cancer and maybe colon cancer. The risk of breast cancer caused by inherited gene changes depends on the type of gene mutation, family history of cancer, and other factors. Men who have inherited certain changes in the BRCA2 gene have a higher risk of breast, prostate and pancreatic cancers, and lymphoma. Inherited gene changes.

Five percent to 10 percent of all breast cancers are thought to be inherited. Get information about the BRCA1 and BRCA2 genetic mutations and testing for them. Warning Signs When breast cancer first develops, there may be no symptoms at all. But as the cancer grows, it can cause changes that women should watch for. You can help safeguard your health by learning the following warning signs of breast cancer. - a lump or thickening in or near the breast or in the underarm area - a change in the size or shape of the breast - a dimple or puckering in the skin of the breast - a nipple turned inward into the breast - fluid, other than breast milk, from the nipple, especially if it's bloody - scaly, red, or swollen skin on the breast, nipple, or areola (the dark area of skin around the nipple) - dimples in the breast that look like the skin of an orange. a lump or thickening in or near the breast or in the underarm area a change in the size or shape of the breast a dimple or puckering in the skin of the breast a nipple turned inward into the breast fluid, other than breast milk, from the nipple, especially if it's bloody scaly, red, or swollen skin on the breast, nipple, or areola (the dark area of skin around the nipple) dimples in the breast that look like the skin of an orange. Don't Ignore Symptoms You should see your doctor about any symptoms like these. Most often, they are not cancer, but it's important to check with the doctor so that any problems can be diagnosed and treated as early as possible. Some women believe that as they age, health problems are due to "growing older." Because of this myth, many illnesses go undiagnosed and untreated. Don't ignore your symptoms because you think they are not important or because you believe they are normal for your age. Talk to your doctor.

### Question: How to diagnose Alzheimer's Caregiving ? ### Response:

Now that your family member or friend has received a diagnosis of Alzheimers disease, its important to learn as much as you can about the disease and how to care for someone who has it. You may also want to know the right way to share the news with family and friends. Learning About Alzheimers Sometimes, you may feel that you don't know how to care for the person with Alzheimers. This is a common feeling among caregivers of people with Alzheimers because each day may bring different challenges. Learning about the disease can help you understand and cope with these challenges. Here is some information about Alzheimers and ways you can learn more about it. Alzheimers disease is an illness of the brain. It causes large numbers of nerve cells in the brain to die. This affects a persons ability to remember things and think clearly. People with Alzheimers become forgetful and easily confused and may have a hard time concentrating. They may have trouble taking care of themselves and doing basic things like making meals, bathing, and getting dressed. Alzheimers varies from person to person. It can progress faster in some people than in others, and not everyone will have the same symptoms. In general, though, Alzheimers takes many years to develop, becoming increasingly severe over time. As the disease gets worse, people need more help. Eventually, they require total care. Alzheimer's disease consists of three main stages: mild (sometimes called early-stage), moderate, and severe (sometimes called late-stage). Understanding these stages can help you care for your loved one and plan ahead. Mild Alzheimers Disease In the mild stage of Alzheimers, people often have some memory loss and small changes in personality. They may have trouble remembering recent events or the names of familiar people or things. They may no longer be able to solve simple math problems or balance a checkbook. People with mild Alzheimers also slowly lose the ability to plan and organize. For example, they may have trouble making a grocery list and finding items in the store. Moderate Alzheimers Disease In the moderate stage of Alzheimers, memory loss and confusion become more obvious. People have more trouble organizing, planning, and following instructions. They may need help getting dressed and may start having problems with bladder or bowel control. People with moderate Alzheimers may have trouble recognizing family members and friends. They may not know where they are or what day or year it is. They also may begin to wander, so they should not be left alone. Personality changes can become more serious. For example, people may make threats or accuse others of stealing. Severe Alzheimers Disease In the severe stage of Alzheimer's, people usually need help with all of their daily needs. They may not be able to walk or sit up without help. They may not be able to talk and often cannot recognize family members. They may have trouble swallowing and refuse to eat. For a short overview of Alzheimers, see Understanding Alzheimers Disease: What You Need to Know. Learn More About Alzheimers Disease So far, there is no cure for Alzheimers, but there are treatments that can prevent some symptoms from getting worse for a limited time. Here are some ways you can learn more about Alzheimers disease. - Talk with a doctor or other healthcare provider who specializes in Alzheimers disease. - Check out books or videos about Alzheimers from the library. - Go to educational programs about the disease. - Visit the website of the National Institute on Agings Alzheimers Disease Education and Referral (ADEAR) Center. The Institute has a guide, Caring for a Person with Alzheimers Disease,which can be viewed online and ordered in print. - Read about Alzheimers disease on NIHSeniorHealth. - Find a support group for caregivers, ideally one in which members are taking care of someone who is in the same stage of Alzheimers as the person you are caring for.

Find a support group for caregivers, ideally one in which members are taking care of someone who is in the same stage of Alzheimers as the person you are caring for. Talking With Family and Friends When you learn that someone has Alzheimers disease, you may wonder when and how to tell your family and friends. You may be worried about how others will react to or treat the person. Others often sense that something is wrong before they are told. Alzheimers disease is hard to keep secret. When the time seems right, be honest with family, friends, and others. Use this as a chance to educate them about Alzheimers disease. You can share information to help them understand what you and the person with Alzheimers are going through. You can also tell them what they can do to help. You can help family and friends understand how to interact with the person who has Alzheimers. - Help them realize what the person can still do and how much he or she can still understand. - Give them suggestions about how to start talking with the person. For example, "Hello George, I'm John. We used to work together." - Help them avoid correcting the person with Alzheimers if he or she makes a mistake or forgets something. - Help them plan fun activities with the person, such as going to family reunions or visiting old friends. Help them realize what the person can still do and how much he or she can still understand. Give them suggestions about how to start talking with the person. For example, "Hello George, I'm John. We used to work together." Help them avoid correcting the person with Alzheimers if he or she makes a mistake or forgets something. Help them plan fun activities with the person, such as going to family reunions or visiting old friends. Helping Children Understand Alzheimers If the person with Alzheimers has young children or grandchildren, you can help them understand what is happening. Answer their questions simply and honestly. For example, you might tell a young child, "Grandma has an illness that makes it hard for her to remember things." Know that their feelings of sadness and anger are normal. Comfort them. Tell them they didn't cause the disease. If the child lives with someone who has Alzheimers, don't expect him or her to "babysit" the person. Make sure the child has time for his or her own interests and needs, such as playing with friends and going to school activities. Spend time with the child, so he or she doesn't feel that all your attention is on the person with Alzheimers. Many younger children will look to you to see how to act around the person with Alzheimers disease. Show children they can still talk with the person and help them enjoy things. Doing fun things together, like arts and crafts or looking through photo albums, can help both the child and the person with Alzheimer's. Challenges for Teens A teenager might find it hard to accept how the person with Alzheimers has changed. He or she may find the changes upsetting or embarrassing and not want to be around the person. Talk with teenagers about their concerns and feelings. Don't force them to spend time with the person who has Alzheimers.

### Question: What are the treatments for What I need to know about Interstitial Cystitis/Painful Bladder Syndrome ? ### Response:

No one treatment for IC/PBS has been found that works for everyone. Your doctor or nurse will work with you to find a treatment plan that meets your special needs. The plan may include diet and lifestyle changes, bladder retraining, activity and exercise, physical therapy, and various types of medicines. You should expect some treatment failures along the way, but, with time, you and your doctor or nurse should find a treatment that gives you some relief and helps you cope with your disease. Diet and Lifestyle Changes Some people with IC/PBS find that certain foods or drinks bring on their symptoms. Others find no link between symptoms and what they eat. Learning what foods cause symptoms for you may require some trial and error. Keep a food diary and note the times you have bladder pain. The diary might reveal that your flare-ups always happen, for example, after you eat tomatoes or oranges. Some doctors recommend taking an antacid medicine with meals. The medicine reduces the amount of acid that gets into the urine. If you make changes to your diet, remember to eat a variety of healthy foods. Bladder Retraining Bladder retraining is a way to help your bladder hold more urine. People with bladder pain often get in the habit of using the bathroom as soon as they feel pain or urgency. They then feel the need to go before the bladder is really full. The body may get used to frequent voiding. Bladder retraining helps your bladder hold more urine before signaling the urge to urinate. Keep a bladder diary to track how you are doing. Start by noting the times when you void. Note how much time goes by between voids. For example, you may find that you return to the bathroom every 40 minutes. Try to stretch out the time between voids. If you usually void every 40 minutes, try to wait at least 50 minutes before you go to the bathroom. If your bladder becomes painful, you may use the bathroom. But you may find that your first urge to use the bathroom goes away if you ignore it. Find ways to relax or distract yourself when the first urge strikes. After a few days, you may be able to stretch the time out to 60 or 70 minutes, and you may find that the urge to urinate does not return as soon. Activity If you have IC/PBS, you may feel the last thing you want to do is exercise. But many people feel that easy activities like walking or gentle stretching exercises help relieve symptoms. Physical Therapy Your doctor or nurse may suggest pelvic exercises. The pelvic muscles hold the bladder in place and help control urination. The first step is to find the right muscle to squeeze. A doctor, nurse, or physical therapist can help you. One way to find the muscles is to imagine that you are trying to stop passing gas. Squeeze the muscles you would use. If you sense a "pulling" feeling, you have found the right muscles for pelvic exercises. You may need exercises to strengthen those muscles so that it's easier to hold in urine. Or you may need to learn to relax your pelvic muscles if tense muscles are part of your bladder pain. Some physical therapists specialize in helping people with pelvic pain. Ask your doctor or nurse to help you find a professional trained in pelvic floor physical therapy. Reducing Stress Stress doesn't cause IC/PBS. But stress can trigger painful flare-ups in someone who has IC/PBS. Learning to reduce stress in your life by making time for relaxation every day may help control some symptoms of IC/PBS. Oral Medicines Pain pills like aspirin, ibuprofen, or acetominophen can help control mild bladder pain. Advil and Motrin are examples of ibuprofen. Tylenol is an example of acetominophen. Talk with your doctor if you feel you need a stronger pain medicine. Your doctor may recommend a medication, pentosan polysulfate sodium, sold as Elmiron, which is approved for treating the pain of IC/PBS. You may need to take this medicine for up to 6 months before you notice improvement. Elmiron does not work for everyone, but some people with IC/PBS have found relief taking it. You need a doctor's order for Elmiron. If you don't notice improvement of your symptoms in 6 months, this medicine is not likely to work. Researchers are also looking at other kinds of medicines. Medicines that treat heartburn might help bladder symptoms by reducing the amount of acid made in the body. Muscle relaxants can keep the bladder from squeezing at the wrong time. Keeping the bladder muscle relaxed helps ease the symptoms of IC/PBS. Bladder Stretching The doctor may stretch the bladder by filling it with liquid. You will be given an anesthetic to prevent pain and help relax your bladder muscles. Some patients have said their symptoms were helped after this treatment. Bladder Medicines Many patients who have IC/PBS find relief after a treatment in which their bladders are filled with a liquid medicine. The doctor guides a tube into your bladder and slowly fills the bladder with a liquid that eases irritation of the bladder wall. The liquid may be a compound called DMSO or a solution that contains heparin and a pain medicine called lidocaine. You will keep the liquid in your bladder for about 15 minutes and then release it. You can have this treatment once every week or every other week for 1 or 2 months. You may not feel any better until the third or fourth treatment. Nerve Stimulation If you have tried diet changes, exercise, and medicines and nothing seems to help, you may wish to think about nerve stimulation. This treatment sends mild electrical pulses to the nerves that control the bladder. At first, you may try a system that sends the pulses through electrodes placed on your skin. If this therapy works for you, you may consider having a device put in your body. The device delivers small pulses of electricity to the nerves around the bladder. For some patients, nerve stimulation relieves bladder pain as well as urinary frequency and urgency. For others, the treatment relieves frequency and urgency but not pain. For still other patients, it does not work. Scientists are not sure why nerve stimulation works. Some believe that the electrical pulses block the pain signals carried in the nerves. If your brain doesn't receive the nerve signal, you don't feel the pain. Others believe that the electricity releases endorphins, which are hormones that block pain naturally. Surgery As a last resort, your doctor might suggest surgery to remove part or all of the bladder. Surgery does not cure the pain of IC/PBS in all cases, but if you have tried every other option and your pain is still unbearable, surgery might be considered. Talk with your doctor and family about the possible benefits and side effects.

### Question: What are the stages of Adult Soft Tissue Sarcoma ? ### Response:

Key Points - After adult soft tissue sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the soft tissue 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 adult soft tissue sarcoma: - Stage I - Stage II - Stage III - Stage IV After adult soft tissue sarcoma has been diagnosed, tests are done to find out if cancer cells have spread within the soft tissue or to other parts of the body. The process used to find out if cancer has spread within the soft tissue or to other parts of the body is called staging. Staging of soft tissue sarcoma is also based on the grade and size of the tumor, whether it is superficial (close to the skin's surface) or deep, and whether it has spread to the lymph nodes or other parts of the body. 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 following tests and procedures may be used in the staging process: - 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. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Complete blood count (CBC): A procedure in which a sample of blood is drawn and checked for the following: - The number of red blood cells, white blood cells, and platelets. - 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. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside of the body, such as the lung and abdomen, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. The results of these tests are viewed together with the results of the tumor biopsy to find out the stage of the soft tissue sarcoma before treatment is given. Sometimes chemotherapy or radiation therapy is given as the initial treatment and afterwards the soft tissue sarcoma is staged again. 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 soft tissue sarcoma spreads to the lung, the cancer cells in the lung are actually soft tissue sarcoma cells. The disease is metastatic soft tissue sarcoma, not lung cancer. The following stages are used for adult soft tissue sarcoma: Stage I Stage I is divided into stages IA and IB: - In stage IA, the tumor is low-grade (likely to grow and spread slowly) and 5 centimeters or smaller. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue). - In stage IB, the tumor is low-grade (likely to grow and spread slowly) and larger than 5 centimeters. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue). Stage II Stage II is divided into stages IIA and IIB: - In stage IIA, the tumor is mid-grade (somewhat likely to grow and spread quickly) or high-grade (likely to grow and spread quickly) and 5 centimeters or smaller. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue). - In stage IIB, the tumor is mid-grade (somewhat likely to grow and spread quickly) and larger than 5 centimeters. It may be either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue). Stage III In stage III, the tumor is either: - high-grade (likely to grow and spread quickly), larger than 5 centimeters, and either superficial (in subcutaneous tissue with no spread into connective tissue or muscle below) or deep (in the muscle and may be in connective or subcutaneous tissue); or - any grade, any size, and has spread to nearby lymph nodes. Stage III cancer that has spread to the lymph nodes is advanced stage III. Stage IV In stage IV, the tumor is any grade, any size, and may have spread to nearby lymph nodes. Cancer has spread to distant parts of the body, such as the lungs.

### Question: What causes Lung Cancer ? ### Response:

Tobacco Products and Cancer Using tobacco products has been shown to cause cancer. In fact, smoking tobacco, using smokeless tobacco, and being exposed regularly to secondhand tobacco smoke are responsible for a large number of cancer deaths in the U.S. each year. Cigarette Smoking Causes Lung Cancer Cigarette smoking is the number one cause of lung cancer. Scientists have reported widely on the link between cancer and smoking since the 1960s. Since then, study after study has provided more proof that cigarette smoking is the primary cause of lung cancer. Before cigarette smoking became popular after World War I, doctors rarely, if ever, saw patients with lung cancer. But today, lung cancer is the leading cause of death by cancer. Over 85 percent of people with lung cancer developed it because they smoked cigarettes. If You Smoke If you smoke cigarettes, you are at much higher risk for lung cancer than a person who has never smoked. The risk of dying from lung cancer is 23 times higher for men who smoke and 13 times higher for women who smoke than for people who have never smoked. Lung cancer can affect young and old alike. Stopping smoking greatly reduces your risk for developing lung cancer. After you stop, your risk levels off. Ten years after the last cigarette, the risk of dying from lung cancer drops by 50 percent -- which does not mean, however, that risk is eliminated. (Watch the videos on this page to learn more about lung cancer, smoking and older adults. To enlarge the videos, click the brackets in the lower right-hand corner of the video screen. To reduce the videos, press the Escape (Esc) button on your keyboard.) Smoking cigars and pipes also puts you at risk for lung cancer. Cigar and pipe smokers have a higher risk of lung cancer than nonsmokers. Even cigar and pipe smokers who do not inhale are at increased risk for lung, mouth, and other types of cancer. The likelihood that a smoker will develop lung cancer is related to the age smoking began; how long the person smoked; the number of cigarettes, pipes, or cigars smoked per day; and how deeply the smoker inhaled. Learn about lung cancer prevention. Other Factors That Increase Your Risk - Many studies suggest that non-smokers who are exposed to environmental tobacco smoke, also called secondhand smoke, are at increased risk of lung cancer. Secondhand smoke is the smoke that non-smokers are exposed to when they share air space with someone who is smoking. Tobacco smoke contains more than 7,000 chemicals, including hundreds that are toxic and about 70 that can cause cancer. Since 1964, approximately 2,500,000 nonsmokers have died from health problems caused by exposure to secondhand smoke. - Exposure to radon can put a person at risk for lung cancer, too. People who work in mines may be exposed to this invisible, odorless, and radioactive gas that occurs naturally in soil and rocks. It is also found in houses in some parts of the country. A kit available at most hardware stores allows homeowners to measure radon levels in their homes. - Another substance that can contribute to lung cancer is asbestos. Asbestos has been used in shipbuilding, asbestos mining and manufacturing, insulation work, and brake repair, although products with asbestos have been largely phased out over the past several decades. If inhaled, asbestos particles can lodge in the lungs, damaging cells and increasing the risk for lung cancer.

It's Never Too Late To Quit Researchers continue to study the causes of lung cancer and to search for ways to prevent it. We already know that the best way to prevent lung cancer is to quit or never start smoking. The sooner a person quits smoking the better. Even if you have been smoking for many years, it's never too late to benefit from quitting.

### Question: What are the treatments for Anemia ? ### Response:

Treatment for anemia depends on the type, cause, and severity of the condition. Treatments may include dietary changes or supplements, medicines, procedures, or surgery to treat blood loss. Goals of Treatment The goal of treatment is to increase the amount of oxygen that your blood can carry. This is done by raising the red blood cell count and/or hemoglobin level. (Hemoglobin is the iron-rich protein in red blood cells that carries oxygen to the body.) Another goal is to treat the underlying cause of the anemia. Dietary Changes and Supplements Low levels of vitamins or iron in the body can cause some types of anemia. These low levels might be the result of a poor diet or certain diseases or conditions. To raise your vitamin or iron level, your doctor may ask you to change your diet or take vitamin or iron supplements. Common vitamin supplements are vitamin B12 and folic acid (folate). Vitamin C sometimes is given to help the body absorb iron. Iron Your body needs iron to make hemoglobin. Your body can more easily absorb iron from meats than from vegetables or other foods. To treat your anemia, your doctor may suggest eating more meatespecially red meat (such as beef or liver), as well as chicken, turkey, pork, fish, and shellfish. Nonmeat foods that are good sources of iron include: Spinach and other dark green leafy vegetables Tofu Peas; lentils; white, red, and baked beans; soybeans; and chickpeas Dried fruits, such as prunes, raisins, and apricots Prune juice Iron-fortified cereals and breads You can look at the Nutrition Facts label on packaged foods to find out how much iron the items contain. The amount is given as a percentage of the total amount of iron you need every day. Iron also is available as a supplement. It's usually combined with multivitamins and other minerals that help your body absorb iron. Doctors may recommend iron supplements for premature infants, infants and young children who drink a lot of cow's milk, and infants who are fed breast milk only or formula that isn't fortified with iron. Large amounts of iron can be harmful, so take iron supplements only as your doctor prescribes. Vitamin B12 Low levels of vitamin B12 can lead to pernicious anemia. This type of anemia often is treated with vitamin B12 supplements. Good food sources of vitamin B12 include: Breakfast cereals with added vitamin B12 Meats such as beef, liver, poultry, and fish Eggs and dairy products (such as milk, yogurt, and cheese) Foods fortified with vitamin B12, such as soy-based beverages and vegetarian burgers Folic Acid Folic acid (folate) is a form of vitamin B that's found in foods. Your body needs folic acid to make and maintain new cells. Folic acid also is very important for pregnant women. It helps them avoid anemia and promotes healthy growth of the fetus. Good sources of folic acid include: Bread, pasta, and rice with added folic acid Spinach and other dark green leafy vegetables Black-eyed peas and dried beans Beef liver Eggs Bananas, oranges, orange juice, and some other fruits and juices Vitamin C Vitamin C helps the body absorb iron. Good sources of vitamin C are vegetables and fruits, especially citrus fruits. Citrus fruits include oranges, grapefruits, tangerines, and similar fruits. Fresh and frozen fruits, vegetables, and juices usually have more vitaminC than canned ones. If you're taking medicines, ask your doctor or pharmacist whether you can eat grapefruit or drink grapefruit juice. This fruit can affect the strength of a few medicines and how well they work. Other fruits rich in vitamin C include kiwi fruit, strawberries, and cantaloupes. Vegetables rich in vitamin C include broccoli, peppers, Brussels sprouts, tomatoes, cabbage, potatoes, and leafy green vegetables like turnip greens and spinach. Medicines Your doctor may prescribe medicines to help your body make more red blood cells or to treat an underlying cause of anemia. Some of these medicines include: Antibiotics to treat infections. Hormones to treat heavy menstrual bleeding in teenaged and adult women. A man-made version of erythropoietin to stimulate your body to make more red blood cells. This hormone has some risks. You and your doctor will decide whether the benefits of this treatment outweigh the risks. Medicines to prevent the body's immune system from destroying its own red blood cells. Chelation (ke-LAY-shun) therapy for lead poisoning. Chelation therapy is used mainly in children. This is because children who have iron-deficiency anemia are at increased risk of lead poisoning. Procedures If your anemia is severe, your doctor may recommend a medical procedure. Procedures include blood transfusions and blood and marrow stem cell transplants. Blood Transfusion A blood transfusion is a safe, common procedure in which blood is given to you through an intravenous (IV) line in one of your blood vessels. Transfusions require careful matching of donated blood with the recipient's blood. For more information, go to the Health Topics Blood Transfusion article. Blood and Marrow Stem Cell Transplant A blood and marrow stem cell transplant replaces your faulty stem cells with healthy ones from another person (a donor). Stem cells are made in the bone marrow. They develop into red and white blood cells and platelets. During the transplant, which is like a blood transfusion, you get donated stem cells through a tube placed in a vein in your chest. Once the stem cells are in your body, they travel to your bone marrow and begin making new blood cells. For more information, go to the Health Topics Blood and Marrow Stem Cell Transplant article. Surgery If you have serious or life-threatening bleeding that's causing anemia, you may need surgery. For example, you may need surgery to control ongoing bleeding due to a stomach ulcer or colon cancer. If your body is destroying red blood cells at a high rate, you may need to have your spleen removed. The spleen is an organ that removes wornout red blood cells from the body. An enlarged or diseased spleen may remove more red blood cells than normal, causing anemia.

### Question: What are the stages of Endometrial Cancer ? ### Response:

Key Points - After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus 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 endometrial cancer: - Stage I - Stage II - Stage III - Stage IV - Endometrial cancer may be grouped for treatment as follows: - Low-risk endometrial cancer - High-risk endometrial cancer After endometrial cancer has been diagnosed, tests are done to find out if cancer cells have spread within the uterus or to other parts of the body. The process used to find out whether the cancer has spread within the uterus 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. Certain tests and procedures are used in the staging process. A hysterectomy (an operation in which the uterus is removed) will usually be done to treat endometrial cancer. Tissue samples are taken from the area around the uterus and checked under a microscope for signs of cancer to help find out whether the cancer has spread. The following procedures may be used in the staging process: - Pelvic exam : An exam of the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum. A speculum is inserted into the vagina and the doctor or nurse looks at the vagina and cervix for signs of disease. A Pap test of the cervix is usually done. The doctor or nurse also inserts one or two lubricated, gloved fingers of one hand into the vagina and places the other hand over the lower abdomen to feel the size, shape, and position of the uterus and ovaries. The doctor or nurse also inserts a lubricated, gloved finger into the rectum to feel for lumps or abnormal areas. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - Lymph node dissection : A surgical procedure in which the lymph nodes are removed from the pelvic area and a sample of tissue is checked under a microscope for signs of cancer. This procedure is also called lymphadenectomy. 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 endometrial cancer spreads to the lung, the cancer cells in the lung are actually endometrial cancer cells. The disease is metastatic endometrial cancer, not lung cancer. The following stages are used for endometrial cancer: Stage I In stage I, cancer is found in the uterus only. Stage I is divided into stages IA and IB, based on how far the cancer has spread. - Stage IA: Cancer is in the endometrium only or less than halfway through the myometrium (muscle layer of the uterus). - Stage IB: Cancer has spread halfway or more into the myometrium. Stage II In stage II, cancer has spread into connective tissue of the cervix, but has not spread outside the uterus. Stage III In stage III, cancer has spread beyond the uterus and cervix, but has not spread beyond the pelvis. Stage III is divided into stages IIIA, IIIB, and IIIC, based on how far the cancer has spread within the pelvis. - Stage IIIA: Cancer has spread to the outer layer of the uterus and/or to the fallopian tubes, ovaries, and ligaments of the uterus. - Stage IIIB: Cancer has spread to the vagina and/or to the parametrium (connective tissue and fat around the uterus). - Stage IIIC: Cancer has spread to lymph nodes in the pelvis and/or around the aorta (largest artery in the body, which carries blood away from the heart). Stage IV In stage IV, cancer has spread beyond the pelvis. Stage IV is divided into stages IVA and IVB, based on how far the cancer has spread. - Stage IVA: Cancer has spread to the bladder and/or bowel wall. - Stage IVB: Cancer has spread to other parts of the body beyond the pelvis, including the abdomen and/or lymph nodes in the groin. Endometrial cancer may be grouped for treatment as follows: Low-risk endometrial cancer Grades 1 and 2 tumors are usually considered low-risk. They usually do not spread to other parts of the body. High-risk endometrial cancer Grade 3 tumors are considered high-risk. They often spread to other parts of the body. Uterine papillary serous, clear cell, and carcinosarcoma are three subtypes of endometrial cancer that are considered grade 3.

### Question: What causes Thrombocytopenia ? ### Response:

Many factors can cause thrombocytopenia (a low platelet count). The condition can be inherited or acquired. "Inherited" means your parents pass the gene for the condition to you. "Acquired" means you aren't born with the condition, but you develop it. Sometimes the cause of thrombocytopenia isn't known. In general, a low platelet count occurs because: The body's bone marrow doesn't make enough platelets. The bone marrow makes enough platelets, but the body destroys them or uses them up. The spleen holds on to too many platelets. A combination of the above factors also may cause a low platelet count. The Bone Marrow Doesn't Make Enough Platelets Bone marrow is the sponge-like tissue inside the bones. It contains stem cells that develop into red blood cells, white blood cells, and platelets. When stem cells are damaged, they don't grow into healthy blood cells. Many conditions and factors can damage stem cells. Cancer Cancer, such as leukemia (lu-KE-me-ah) or lymphoma (lim-FO-ma), can damage the bone marrow and destroy blood stem cells. Cancer treatments, such as radiation and chemotherapy, also destroy the stem cells. Aplastic Anemia Aplastic anemia is a rare, serious blood disorder in which the bone marrow stops making enough new blood cells. This lowers the number of platelets in your blood. Toxic Chemicals Exposure to toxic chemicalssuch as pesticides, arsenic, and benzenecan slow the production of platelets. Medicines Some medicines, such as diuretics and chloramphenicol, can slow the production of platelets. Chloramphenicol (an antibiotic) rarely is used in the United States. Common over-the-counter medicines, such as aspirin or ibuprofen, also can affect platelets. Alcohol Alcohol also slows the production of platelets. A temporary drop in the platelet count is common among heavy drinkers, especially if they're eating foods that are low in iron, vitamin B12, or folate. Viruses Chickenpox, mumps, rubella, Epstein-Barr virus, or parvovirus can decrease your platelet count for a while. People who have AIDS often develop thrombocytopenia. Genetic Conditions Some genetic conditions can cause low numbers of platelets in the blood. Examples include Wiskott-Aldrich and May-Hegglin syndromes. The Body Destroys Its Own Platelets A low platelet count can occur even if the bone marrow makes enough platelets. The body may destroy its own platelets due to autoimmune diseases, certain medicines, infections, surgery, pregnancy, and some conditions that cause too much blood clotting. Autoimmune Diseases Autoimmune diseases occur if the body's immune system mistakenly attacks healthy cells in the body. If an autoimmune disease destroys the body's platelets, thrombocytopenia can occur. One example of this type of autoimmune disease is immune thrombocytopenia (ITP). ITP is a bleeding disorder in which the blood doesn't clot as it should. An autoimmune response is thought to cause most cases of ITP. Normally, your immune system helps your body fight off infections and diseases. But if you have ITP, your immune system attacks and destroys its own platelets. Why this happens isn't known. (ITP also may occur if the immune system attacks your bone marrow, which makes platelets.) Other autoimmune diseases that destroy platelets include lupus and rheumatoid arthritis. Medicines A reaction to medicine can confuse your body and cause it to destroy its platelets. Examples of medicines that may cause this to happen include quinine; antibiotics that contain sulfa; and some medicines for seizures, such as Dilantin, vancomycin, and rifampin. (Quinine is a substance often found in tonic water and nutritional health products.) Heparin is a medicine commonly used to prevent blood clots. But an immune reaction may trigger the medicine to cause blood clots and thrombocytopenia. This condition is called heparin-induced thrombocytopenia (HIT). HIT rarely occurs outside of a hospital. In HIT, the body's immune system attacks a substance formed by heparin and a protein on the surface of the platelets. This attack activates the platelets and they start to form blood clots. Blood clots can form deep in the legs (deep vein thrombosis), or they can break loose and travel to the lungs (pulmonary embolism). Infection A low platelet count can occur after blood poisoning from a widespread bacterial infection. A virus, such as mononucleosis or cytomegalovirus, also can cause a low platelet count. Surgery Platelets can be destroyed when they pass through man-made heart valves, blood vessel grafts, or machines and tubing used for blood transfusions or bypass surgery. Pregnancy About 5 percent of pregnant women develop mild thrombocytopenia when they're close to delivery. The exact cause isn't known for sure. Rare and Serious Conditions That Cause Blood Clots Some rare and serious conditions can cause a low platelet count. Two examples are thrombotic thrombocytopenic purpura (TTP) and disseminated intravascular coagulation (DIC). TTP is a rare blood condition. It causes blood clots to form in the body's small blood vessels, including vessels in the brains, kidneys, and heart. DIC is a rare complication of pregnancy, severe infections, or severe trauma. Tiny blood clots form suddenly throughout the body. In both conditions, the blood clots use up many of the blood's platelets. The Spleen Holds On to Too Many Platelets Usually, one-third of the body's platelets are held in the spleen. If the spleen is enlarged, it will hold on to too many platelets. This means that not enough platelets will circulate in the blood. An enlarged spleen often is due to cancer or severe liver disease, such as cirrhosis (sir-RO-sis). Cirrhosis is a disease in which the liver is scarred. This prevents it from working well. An enlarged spleen also might be due to a bone marrow condition, such as myelofibrosis (MI-eh-lo-fi-BRO-sis). With this condition, the bone marrow is scarred and isn't able to make blood cells.

### Question: What are the stages of Penile Cancer ? ### Response:

Key Points - After penile cancer has been diagnosed, tests are done to find out if cancer cells have spread within the penis 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 penile cancer: - Stage 0 (Carcinoma in Situ) - Stage I - Stage II - Stage III - Stage IV After penile cancer has been diagnosed, tests are done to find out if cancer cells have spread within the penis or to other parts of the body. The process used to find out if cancer has spread within the penis 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 pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. The tissue sample is removed during one of the following procedures: - Sentinel lymph node biopsy : The removal of the sentinel lymph node during surgery. The sentinel lymph node is the first lymph node to receive lymphatic drainage from a tumor. It is the first lymph node the cancer is likely to spread to from the tumor. A radioactive substance and/or blue dye is injected near the tumor. The substance or dye flows through the lymph ducts to the lymph nodes. The first lymph node to receive the substance or dye is removed. A pathologist views the tissue under a microscope to look for cancer cells. If cancer cells are not found, it may not be necessary to remove more lymph nodes. - Lymph node dissection : A procedure to remove one or more lymph nodes during surgery. A sample of tissue is checked under a microscope for signs of cancer. This procedure is also called a lymphadenectomy. 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 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 penile cancer spreads to the lung, the cancer cells in the lung are actually penile cancer cells. The disease is metastatic penile cancer, not lung cancer. The following stages are used for penile cancer: Stage 0 (Carcinoma in Situ) In stage 0, abnormal cells or growths that look like warts are found on the surface of the skin of the penis. These abnormal cells or growths may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. Stage I In stage I, cancer has formed and spread to connective tissue just under the skin of the penis. Cancer has not spread to lymph vessels or blood vessels. The tumor cells look a lot like normal cells under a microscope. Stage II In stage II, cancer has spread: - to connective tissue just under the skin of the penis. Also, cancer has spread to lymph vessels or blood vessels or the tumor cells may look very different from normal cells under a microscope; or - through connective tissue to erectile tissue (spongy tissue that fills with blood to make an erection); or - beyond erectile tissue to the urethra. Stage III Stage III is divided into stage IIIa and stage IIIb. In stage IIIa, cancer has spread to one lymph node in the groin. Cancer has also spread: - to connective tissue just under the skin of the penis. Also, cancer may have spread to lymph vessels or blood vessels or the tumor cells may look very different from normal cells under a microscope; or - through connective tissue to erectile tissue (spongy tissue that fills with blood to make an erection); or - beyond erectile tissue to the urethra. In stage IIIb, cancer has spread to more than one lymph node on one side of the groin or to lymph nodes on both sides of the groin. Cancer has also spread: - to connective tissue just under the skin of the penis. Also, cancer may have spread to lymph vessels or blood vessels or the tumor cells may look very different from normal cells under a microscope; or - through connective tissue to erectile tissue (spongy tissue that fills with blood to make an erection); or - beyond erectile tissue to the urethra. Stage IV In stage IV, cancer has spread: - to tissues near the penis such as the prostate, and may have spread to lymph nodes in the groin or pelvis; or - to one or more lymph nodes in the pelvis, or cancer has spread from the lymph nodes to the tissues around the lymph nodes; or - to distant parts of the body.

### Question: What are the treatments for Angina ? ### Response:

Treatments for angina include lifestyle changes, medicines, medical procedures, cardiac rehabilitation (rehab), and other therapies. The main goals of treatment are to: Reduce pain and discomfort and how often it occurs Prevent or lower your risk for heart attack and death by treating your underlying heart condition Lifestyle changes and medicines may be the only treatments needed if your symptoms are mild and aren't getting worse. If lifestyle changes and medicines don't control angina, you may need medical procedures or cardiac rehab. Unstable angina is an emergency condition that requires treatment in a hospital. Lifestyle Changes Making lifestyle changes can help prevent episodes of angina. You can: Slow down or take rest breaks if physical exertion triggers angina. Avoid large meals and rich foods that leave you feeling stuffed if heavy meals trigger angina. Try to avoid situations that make you upset or stressed if emotional stress triggers angina. Learn ways to handle stress that can't be avoided. You also can make lifestyle changes that help lower your risk for coronary heart disease. One of the most important changes is to quit smoking. Smoking can damage and tighten blood vessels and raise your risk for CHD. Talk with your doctor about programs and products that can help you quit. Also, try to avoid secondhand smoke. If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking. For more information about how to quit smoking, go to the Diseases and Conditions Index (DCI) Smoking and Your Heart article and the National Heart, Lung, and Blood Institutes (NHLBIs) "Your Guide to a Healthy Heart." Following a healthy diet is another important lifestyle change. A healthy diet can prevent or reduce high blood pressure and high blood cholesterol and help you maintain a healthy weight. A healthy diet includes a variety of fruits and vegetables (including beans and peas). It also includes whole grains, lean meats, poultry without skin, seafood, and fat-free or low-fat milk and dairy products. A healthy diet also is low in sodium (salt), added sugars, solid fats, and refined grains. For more information about following a healthy diet, go to the NHLBIs Your Guide to Lowering Your Blood Pressure With DASH and the U.S. Department of Agricultures ChooseMyPlate.gov Web site. Both resources provide general information about healthy eating. Other important lifestyle changes include: Being physically active. Check with your doctor to find out how much and what kinds of activity are safe for you. For more information, go to the DCI Physical Activity and Your Heart article. Maintaining a healthy weight. If youre overweight or obese, work with your doctor to create a reasonable weight-loss plan. Controlling your weight helps you control CHD risk factors. Taking all medicines as your doctor prescribes, especially if you have diabetes. Medicines Nitrates are the medicines most commonly used to treat angina. They relax and widen blood vessels. This allows more blood to flow to the heart, while reducing the hearts workload. Nitroglycerin (NI-tro-GLIS-er-in) is the most commonly used nitrate for angina. Nitroglycerin that dissolves under your tongue or between your cheek and gum is used to relieve angina episodes. Nitroglycerin pills and skin patches are used to prevent angina episodes. However, pills and skin patches act too slowly to relieve pain during an angina attack. Other medicines also are used to treat angina, such as beta blockers, calcium channel blockers, ACE inhibitors, oral antiplatelet medicines, or anticoagulants (blood thinners). These medicines can help: Lower blood pressure and cholesterol levels Slow the heart rate Relax blood vessels Reduce strain on the heart Prevent blood clots from forming People who have stable angina may be advised to get annual flu shots. Medical Procedures If lifestyle changes and medicines don't control angina, you may need a medical procedure to treat the underlying heart disease. Both angioplasty (AN-jee-oh-plas-tee) and coronary artery bypass grafting (CABG) are commonly used to treat heart disease. Angioplasty opens blocked or narrowed coronary arteries. During angioplasty, a thin tube with a balloon or other device on the end is threaded through a blood vessel to the narrowed or blocked coronary artery. Once in place, the balloon is inflated to push the plaque outward against the wall of the artery. This widens the artery and restores blood flow. Angioplasty can improve blood flow to your heart and relieve chest pain. A small mesh tube called a stent usually is placed in the artery to help keep it open after the procedure. During CABG, healthy arteries or veins taken from other areas in your body are used to bypass (that is, go around) your narrowed coronary arteries. Bypass surgery can improve blood flow to your heart, relieve chest pain, and possibly prevent a heart attack. You will work with your doctor to decide which treatment is better for you. Cardiac Rehabilitation Your doctor may recommend cardiac rehab for angina or after angioplasty, CABG, or a heart attack. Cardiac rehab is a medically supervised program that can help improve the health and well-being of people who have heart problems. The cardiac rehab team may include doctors, nurses, exercise specialists, physical and occupational therapists, dietitians or nutritionists, and psychologists or other mental health specialists. Rehab has two parts: Exercise training. This part helps you learn how to exercise safely, strengthen your muscles, and improve your stamina. Your exercise plan will be based on your personal abilities, needs, and interests. Education, counseling, and training. This part of rehab helps you understand your heart condition and find ways to reduce your risk for future heart problems. The rehab team will help you learn how to adjust to a new lifestyle and deal with your fears about the future. For more information about cardiac rehab, go to the DCI Cardiac Rehabilitation article. Enhanced External Counterpulsation Therapy Enhanced external counterpulsation (EECP) therapy is helpful for some people who have angina. Large cuffs, similar to blood pressure cuffs, are put on your legs. The cuffs are inflated and deflated in sync with your heartbeat. EECP therapy improves the flow of oxygen-rich blood to your heart muscle and helps relieve angina. You typically get 35 1-hour treatments over 7 weeks.

### Question: What causes Overview of Kidney Disease in Children ? ### Response:

Kidney disease in children can be caused by - birth defects - hereditary diseases - infection - nephrotic syndrome - systemic diseases - trauma - urine blockage or reflux From birth to age 4, birth defects and hereditary diseases are the leading causes of kidney failure. Between ages 5 and 14, kidney failure is most commonly caused by hereditary diseases, nephrotic syndrome, and systemic diseases. Between ages 15 and 19, diseases that affect the glomeruli are the leading cause of kidney failure, and hereditary diseases become less common.1 Birth Defects A birth defect is a problem that happens while a baby is developing in the mothers womb. Birth defects that affect the kidneys include renal agenesis, renal dysplasia, and ectopic kidney, to name a few. These defects are abnormalities of size, structure, or position of the kidneys: - renal agenesischildren born with only one kidney - renal dysplasiachildren born with both kidneys, yet one does not function - ectopic kidneychildren born with a kidney that is located below, above, or on the opposite side of its usual position In general, children with these conditions lead full, healthy lives. However, some children with renal agenesis or renal dysplasia are at increased risk for developing kidney disease. Hereditary Diseases Hereditary kidney diseases are illnesses passed from parent to child through the genes. One example is polycystic kidney disease (PKD), characterized by many grapelike clusters of fluid-filled cystsabnormal sacsthat make both kidneys larger over time. These cysts take over and destroy working kidney tissue. Another hereditary disease is Alport syndrome, which is caused by a mutation in a gene for a type of protein called collagen that makes up the glomeruli. The condition leads to scarring of the kidneys. Alport syndrome generally develops in early childhood and is more serious in boys than in girls. The condition can lead to hearing and vision problems in addition to kidney disease. Infection Hemolytic uremic syndrome and acute post-streptococcal glomerulonephritis are kidney diseases that can develop in a child after an infection. - Hemolytic uremic syndrome is a rare disease that is often caused by the Escherichia coli (E. coli) bacterium found in contaminated foods, such as meat, dairy products, and juice. Hemolytic uremic syndrome develops when E. coli bacteria lodged in the digestive tract make toxins that enter the bloodstream. The toxins start to destroy red blood cells and damage the lining of the blood vessels, including the glomeruli. Most children who get an E. coli infection have vomiting, stomach cramps, and bloody diarrhea for 2 to 3 days. Children who develop hemolytic uremic syndrome become pale, tired, and irritable. Hemolytic uremic syndrome can lead to kidney failure in some children. - Post-streptococcal glomerulonephritis can occur after an episode of strep throat or a skin infection. The Streptococcus bacterium does not attack the kidneys directly; instead, the infection may stimulate the immune system to overproduce antibodies. Antibodies are proteins made by the immune system. The immune system protects people from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. When the extra antibodies circulate in the blood and finally deposit in the glomeruli, the kidneys can be damaged. Most cases of post-streptococcal glomerulonephritis develop 1 to 3 weeks after an untreated infection, though it may be as long as 6 weeks. Post-streptococcal glomerulonephritis lasts only a brief time and the kidneys usually recover. In a few cases, kidney damage may be permanent. Nephrotic Syndrome Nephrotic syndrome is a collection of symptoms that indicate kidney damage. Nephrotic syndrome includes all of the following conditions: - albuminuriawhen a persons urine contains an elevated level of albumin, a protein typically found in the blood - hyperlipidemiahigher-than-normal fat and cholesterol levels in the blood - edemaswelling, usually in the legs, feet, or ankles and less often in the hands or face - hypoalbuminemialow levels of albumin in the blood Nephrotic syndrome in children can be caused by the following conditions: - Minimal change disease is a condition characterized by damage to the glomeruli that can be seen only with an electron microscope, which shows tiny details better than any other type of microscope. The cause of minimal change disease is unknown; some health care providers think it may occur after allergic reactions, vaccinations, and viral infections. - Focal segmental glomerulosclerosis is scarring in scattered regions of the kidney, typically limited to a small number of glomeruli. - Membranoproliferative glomerulonephritis is a group of autoimmune diseases that cause antibodies to build up on a membrane in the kidney. Autoimmune diseases cause the bodys immune system to attack the bodys own cells and organs. Systemic Diseases Systemic diseases, such as systemic lupus erythematosus (SLE or lupus) and diabetes, involve many organs or the whole body, including the kidneys: - Lupus nephritis is kidney inflammation caused by SLE, which is an autoimmune disease. - Diabetes leads to elevated levels of blood glucose, also called blood sugar, which scar the kidneys and increase the speed at which blood flows into the kidneys. Faster blood flow strains the glomeruli, decreasing their ability to filter blood, and raises blood pressure. Kidney disease caused by diabetes is called diabetic kidney disease. While diabetes is the number one cause of kidney failure in adults, it is an uncommon cause during childhood. More information about systemic kidney diseases is provided in the NIDDK health topics: - Lupus Nephritis - Kidney Disease of Diabetes Trauma Traumas such as burns, dehydration, bleeding, injury, or surgery can cause very low blood pressure, which decreases blood flow to the kidneys. Low blood flow can result in acute kidney failure. Urine Blockage or Reflux When a blockage develops between the kidneys and the urethra, urine can back up into the kidneys and cause damage. Refluxurine flowing from the bladder up to the kidneyhappens when the valve between the bladder and the ureter does not close all the way.

### Question: What is (are) Plasma Cell Neoplasms (Including Multiple Myeloma) ? ### Response:

Key Points - Plasma cell neoplasms are diseases in which the body makes too many plasma cells. - Plasma cell neoplasms can be benign (not cancer) or malignant (cancer). - There are several types of plasma cell neoplasms. - Monoclonal gammopathy of undetermined significance (MGUS) - Plasmacytoma - Multiple myeloma - Multiple myeloma and other plasma cell neoplasms may cause a condition called amyloidosis. - Age can affect the risk of plasma cell neoplasms. - Tests that examine the blood, bone marrow, and urine are used to detect (find) and diagnose multiple myeloma and other plasma cell neoplasms. - Certain factors affect prognosis (chance of recovery) and treatment options. Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cells develop from B lymphocytes (B cells), a type of white blood cell that is made in the bone marrow. Normally, when bacteria or viruses enter the body, some of the B cells will change into plasma cells. The plasma cells make antibodies to fight bacteria and viruses, to stop infection and disease. Plasma cell neoplasms are diseases in which abnormal plasma cells or myeloma cells form tumors in the bones or soft tissues of the body. The plasma cells also make an antibody protein, called M protein, that is not needed by the body and does not help fight infection. These antibody proteins build up in the bone marrow and can cause the blood to thicken or can damage the kidneys. Plasma cell neoplasms can be benign (not cancer) or malignant (cancer). Monoclonal gammopathy of undetermined significance (MGUS) is not cancer but can become cancer. The following types of plasma cell neoplasms are cancer: - Lymphoplasmacytic lymphoma. (See Adult Non-Hodgkin Lymphoma Treatment for more information.) - Plasmacytoma. - Multiple myeloma. There are several types of plasma cell neoplasms. Plasma cell neoplasms include the following: Monoclonal gammopathy of undetermined significance (MGUS) In this type of plasma cell neoplasm, less than 10% of the bone marrow is made up of abnormal plasma cells and there is no cancer. The abnormal plasma cells make M protein, which is sometimes found during a routine blood or urine test. In most patients, the amount of M protein stays the same and there are no signs, symptoms, or health problems. In some patients, MGUS may later become a more serious condition, such as amyloidosis, or cause problems with the kidneys, heart, or nerves. MGUS can also become cancer, such as multiple myeloma, lymphoplasmacytic lymphoma, or chronic lymphocytic leukemia. Plasmacytoma In this type of plasma cell neoplasm, the abnormal plasma cells (myeloma cells) are in one place and form one tumor, called a plasmacytoma. Sometimes plasmacytoma can be cured. There are two types of plasmacytoma. - In isolated plasmacytoma of bone, one plasma cell tumor is found in the bone, less than 10% of the bone marrow is made up of plasma cells, and there are no other signs of cancer. Plasmacytoma of the bone often becomes multiple myeloma. - In extramedullary plasmacytoma, one plasma cell tumor is found in soft tissue but not in the bone or the bone marrow. Extramedullary plasmacytomas commonly form in tissues of the throat, tonsil, and paranasal sinuses. Signs and symptoms depend on where the tumor is. - In bone, the plasmacytoma may cause pain or broken bones. - In soft tissue, the tumor may press on nearby areas and cause pain or other problems. For example, a plasmacytoma in the throat can make it hard to swallow. Multiple myeloma In multiple myeloma, abnormal plasma cells (myeloma cells) build up in the bone marrow and form tumors in many bones of the body. These tumors may keep the bone marrow from making enough healthy blood cells. Normally, the bone marrow makes stem cells (immature cells) that become three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to help prevent bleeding. As the number of myeloma cells increases, fewer red blood cells, white blood cells, and platelets are made. The myeloma cells also damage and weaken the bone. Sometimes multiple myeloma does not cause any signs or symptoms. This is called smoldering multiple myeloma. It may be found when a blood or urine test is done for another condition. Signs and symptoms may be caused by multiple myeloma or other conditions. Check with your doctor if you have any of the following: - Bone pain, especially in the back or ribs. - Bones that break easily. - Fever for no known reason or frequent infections. - Easy bruising or bleeding. - Trouble breathing. - Weakness of the arms or legs. - Feeling very tired. A tumor can damage the bone and cause hypercalcemia (too much calcium in the blood). This can affect many organs in the body, including the kidneys, nerves, heart, muscles, and digestive tract, and cause serious health problems. Hypercalcemia may cause the following signs and symptoms: - Loss of appetite. - Nausea or vomiting. - Feeling thirsty. - Frequent urination. - Constipation. - Feeling very tired. - Muscle weakness. - Restlessness. - Confusion or trouble thinking. Multiple myeloma and other plasma cell neoplasms may cause a condition called amyloidosis. In rare cases, multiple myeloma can cause peripheral nerves (nerves that are not in the brain or spinal cord) and organs to fail. This may be caused by a condition called amyloidosis. Antibody proteins build up and stick together in peripheral nerves and organs, such as the kidney and heart. This can cause the nerves and organs to become stiff and unable to work the way they should. Amyloidosis may cause the following signs and symptoms: - Feeling very tired. - Purple spots on the skin. - Enlarged tongue. - Diarrhea. - Swelling caused by fluid in your body's tissues. - Tingling or numbness in your legs and feet.

### Question: what research (or clinical trials) is being done for Parkinson's Disease ? ### Response:

In recent years, research on Parkinson's has advanced to the point that halting the progression of the disease, restoring lost function, and even preventing the disease are all considered realistic goals. While the goal of preventing Parkinson's disease may take years to achieve, researchers are making great progress in understanding and treating it. Genetics Research One of the most exciting areas of Parkinson's research is genetics. Studying the genes responsible for inherited cases can help researchers understand both inherited and sporadic cases of the disease. Identifying gene defects can also help researchers - understand how Parkinson's occurs - develop animal models that accurately mimic the death of nerve cells in humans - identify new approaches to drug therapy - improve diagnosis. understand how Parkinson's occurs develop animal models that accurately mimic the death of nerve cells in humans identify new approaches to drug therapy improve diagnosis. Researchers funded by the National Institute of Neurological Disorders and Stroke are gathering information and DNA samples from hundreds of families with members who have Parkinson's and are conducting large-scale studies to identify gene variants that are associated with increased risk of developing the disease. They are also comparing gene activity in Parkinson's with gene activity in similar diseases such as progressive supranuclear palsy. In addition to identifying new genes for Parkinson's disease, researchers are trying to learn about the function of genes known to be associated with the disease, and about how gene mutations cause disease. Effects of Environmental Toxins Scientists continue to study environmental toxins such as pesticides and herbicides that can cause Parkinson's symptoms in animals. They have found that exposing rodents to the pesticide rotenone and several other agricultural chemicals can cause cellular and behavioral changes that mimic those seen in Parkinson's. Role of Lewy Bodies Other studies focus on how Lewy bodies form and what role they play in Parkinson's disease. Some studies suggest that Lewy bodies are a byproduct of a breakdown that occurs within nerve cells, while others indicate that Lewy bodies are protective, helping neurons "lock away" abnormal molecules that might otherwise be harmful. Identifying Biomarkers Biomarkers for Parkinson's -- measurable characteristics that can reveal whether the disease is developing or progressing -- are another focus of research. Such biomarkers could help doctors detect the disease before symptoms appear and improve diagnosis of the disease. They also would show if medications and other types of therapy have a positive or negative effect on the course of the disease. The National Disorders of Neurological Disorders and Stroke has developed an initiative, the Parkinsons Disease Biomarkers Identification Network (PD-BIN), designed specifically to address these questions and to discover and validate biomarkers for Parkinsons disease. Transcranial Therapies Researchers are conducting many studies of new or improved therapies for Parkinson's disease. Studies are testing whether transcranial electrical polarization (TEP) or transcranial magnetic stimulation (TMS) can reduce the symptoms of the disease. In TEP, electrodes placed on the scalp are used to generate an electrical current that modifies signals in the brain's cortex. In TMS, an insulated coil of wire on the scalp is used to generate a brief electrical current. Drug Discovery A variety of new drug treatments for Parkinson's disease are in clinical trials. Several MAO-B inhibitors including selegiline, lazabemide, and rasagiline, are being tested to determine if they have neuroprotective effects in people with Parkinsons disease. The National Institute of Neurological Disorders and Stroke has launched a broad effort to find drugs to slow the progression of Parkinson's disease, called NET-PD or NIH Exploratory Trials in Parkinson's Disease. The first studies tested several compounds; one of these, creatine, is now being evaluated in a larger clinical trial. The NET-PD investigators are testing a highly purified form of creatine, a nutritional supplement, to find out if it slows the decline seen in people with Parkinson's. Creatine is a widely used dietary supplement thought to improve exercise performance. Cellular energy is stored in a chemical bond between creatine and a phosphate. More recently, NET-PD has initiated pilot studies to test pioglitazone, a drug that has been shown to stimulate mitochondrial function. Because mitochondrial function may be less active in Parkinsons disease, this drug may protect vulnerable dopamine neurons by boosting mitochondrial function. Cell Implantation Another potential approach to treating Parkinson's disease is to implant cells to replace those lost in the disease. Starting in the 1990s, researchers conducting a controlled clinical trial of fetal tissue implants tried to replace lost dopamine-producing nerve cells with healthy ones from fetal tissue in order to improve movement and the response to medications. While many of the implanted cells survived in the brain and produced dopamine, this therapy was associated with only modest functional improvements, mostly in patients under the age of 60. Some of the people who received the transplants developed disabling dyskinesias that could not be relieved by reducing anti-parkinsonian medications. Stem Cells Another type of cell therapy involves stem cells. Some stem cells derived from embryos can develop into any kind of cell in the body, while others, called progenitor cells, are less flexible. Researchers are developing methods to improve the number of dopamine-producing cells that can be grown from embryonic stem cells in culture. Other researchers are also exploring whether stem cells from adult brains might be useful in treating Parkinson's disease. Recent studies suggest that some adult cells from skin can be reprogrammed to an embryonic-like state, resulting in induced pluripotent stem cells (iPSC) that may someday be used for treatment of Parkinsons. In addition, development and characterization of cells from people with sporadic or inherited Parkinsons may reveal information about cellular mechanisms of disease and identify targets for drug development. Gene Therapy A number of early clinical trials are now underway to test whether gene therapy can improve Parkinson's disease. Genes which are found to improve cellular function in models of Parkinson's are inserted into modified viruses. The genetically engineered viruses are then injected into the brains of people with Parkinson's disease. Clinical studies have focused on the therapeutic potential of neurotrophic factors, including GDNF and neurturin, and enzymes that produce dopamine. These trials will test whether the viruses, by lending to the production of the protective gene product, improve symptoms of Parkinson's over time. The National Institute of Neurological Disorders and Stroke also supports the Morris K. Udall Centers of Excellence for Parkinson's Disease Research program . These Centers, located across the USA, study cellular mechanisms underlying Parkinsons disease, identify and characterize disease-associated genes, and discover and develop potential therapeutic targets. The Centers' multidisciplinary research environment allows scientists to take advantage of new discoveries in the basic, translational and clinical sciences that could lead to clinical advances for Parkinsons disease.

### Question: How to diagnose Prostate Enlargement: Benign Prostatic Hyperplasia ? ### Response:

A health care provider diagnoses benign prostatic hyperplasia based on - a personal and family medical history - a physical exam - medical tests Personal and Family Medical History Taking a personal and family medical history is one of the first things a health care provider may do to help diagnose benign prostatic hyperplasia. A health care provider may ask a man - what symptoms are present - when the symptoms began and how often they occur - whether he has a history of recurrent UTIs - what medications he takes, both prescription and over the counter - how much liquid he typically drinks each day - whether he consumes caffeine and alcohol - about his general medical history, including any significant illnesses or surgeries Physical Exam A physical exam may help diagnose benign prostatic hyperplasia. During a physical exam, a health care provider most often - examines a patients body, which can include checking for - discharge from the urethra - enlarged or tender lymph nodes in the groin - a swollen or tender scrotum - taps on specific areas of the patients body - performs a digital rectal exam A digital rectal exam, or rectal exam, is a physical exam of the prostate. To perform the exam, the health care provider asks the man to bend over a table or lie on his side while holding his knees close to his chest. The health care provider slides a gloved, lubricated finger into the rectum and feels the part of the prostate that lies next to the rectum. The man may feel slight, brief discomfort during the rectal exam. A health care provider most often performs a rectal exam during an office visit, and men do not require anesthesia. The exam helps the health care provider see if the prostate is enlarged or tender or has any abnormalities that require more testing. Many health care providers perform a rectal exam as part of a routine physical exam for men age 40 or older, whether or not they have urinary problems. Medical Tests A health care provider may refer men to a urologista doctor who specializes in urinary problems and the male reproductive systemthough the health care provider most often diagnoses benign prostatic hyperplasia on the basis of symptoms and a digital rectal exam. A urologist uses medical tests to help diagnose lower urinary tract problems related to benign prostatic hyperplasia and recommend treatment. Medical tests may include - urinalysis - a prostate-specific antigen (PSA) blood test - urodynamic tests - cystoscopy - transrectal ultrasound - biopsy Urinalysis. Urinalysis involves testing a urine sample. The patient collects a urine sample in a special container in a health care providers office or a commercial facility. A health care provider tests the sample during an office visit or sends it to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color to indicate signs of infection in urine. PSA blood test. A health care provider may draw blood for a PSA test during an office visit or in a commercial facility and send the sample to a lab for analysis. Prostate cells create a protein called PSA. Men who have prostate cancer may have a higher amount of PSA in their blood. However, a high PSA level does not necessarily indicate prostate cancer. In fact, benign prostatic hyperplasia, prostate infections, inflammation, aging, and normal fluctuations often cause high PSA levels. Much remains unknown about how to interpret a PSA blood test, the tests ability to discriminate between cancer and prostate conditions such as benign prostatic hyperplasia, and the best course of action to take if the PSA level is high. Urodynamic tests. Urodynamic tests include a variety of procedures that look at how well the bladder and urethra store and release urine. A health care provider performs urodynamic tests during an office visit or in an outpatient center or a hospital. Some urodynamic tests do not require anesthesia; others may require local anesthesia. Most urodynamic tests focus on the bladders ability to hold urine and empty steadily and completely and may include the following: - uroflowmetry, which measures how rapidly the bladder releases urine - postvoid residual measurement, which evaluates how much urine remains in the bladder after urination - reduced urine flow or residual urine in the bladder, which often suggests urine blockage due to benign prostatic hyperplasia More information is provided in the NIDDK health topic, Urodynamic Testing. Cystoscopy. Cystoscopy is a procedure that uses a tubelike instrument, called a cystoscope, to look inside the urethra and bladder. A urologist inserts the cystoscope through the opening at the tip of the penis and into the lower urinary tract. A urologist performs cystoscopy during an office visit or in an outpatient center or a hospital. The urologist will give the patient local anesthesia; however, in some cases, the patient may require sedation and regional or general anesthesia. A urologist may use cystoscopy to look for blockage or stones in the urinary tract. More information is provided in the NIDDK health topic, Cystoscopy and Ureteroscopy. Transrectal ultrasound. Transrectal ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The health care provider can move the transducer to different angles to make it possible to examine different organs. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; the patient does not require anesthesia. Urologists most often use transrectal ultrasound to examine the prostate. In a transrectal ultrasound, the technician inserts a transducer slightly larger than a pen into the mans rectum, next to the prostate. The ultrasound image shows the size of the prostate and any abnormalities, such as tumors. Transrectal ultrasound cannot reliably diagnose prostate cancer. Biopsy. Biopsy is a procedure that involves taking a small piece of prostate tissue for examination with a microscope. A urologist performs the biopsy in an outpatient center or a hospital. The urologist will give the patient light sedation and local anesthetic; however, in some cases, the patient will require general anesthesia. The urologist uses imaging techniques such as ultrasound, a computerized tomography scan, or magnetic resonance imaging to guide the biopsy needle into the prostate. A pathologista doctor who specializes in examining tissues to diagnose diseasesexamines the prostate tissue in a lab. The test can show whether prostate cancer is present. More information is provided in the NIDDK health topic, Medical Tests for Prostate Problems.

### Question: What are the treatments for Myelodysplastic Syndromes ? ### Response:

Key Points - There are different types of treatment for patients with myelodysplastic syndromes. - Treatment for myelodysplastic syndromes includes supportive care, drug therapy, and stem cell transplantation. - Three types of standard treatment are used: - Supportive care - Drug therapy - Chemotherapy with stem cell transplant - New types of treatment are being tested in clinical trials. - Patients may want to think about taking part in a clinical trial. - Patients can enter clinical trials before, during, or after starting their treatment. - Follow-up tests may be needed. There are different types of treatment for patients with myelodysplastic syndromes. Different types of treatment are available for patients with myelodysplastic syndromes. Some treatments are standard (the currently used treatment), and some are being tested in clinical trials. A treatment clinical trial is a research study meant to help improve current treatments or obtain information on new treatments for patients with cancer. When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment. Treatment for myelodysplastic syndromes includes supportive care, drug therapy, and stem cell transplantation. Patients with a myelodysplastic syndrome who have symptoms caused by low blood counts are given supportive care to relieve symptoms and improve quality of life. Drug therapy may be used to slow progression of the disease. Certain patients can be cured with aggressive treatment with chemotherapy followed by stem cell transplant using stem cells from a donor. Three types of standard treatment are used: Supportive care Supportive care is given to lessen the problems caused by the disease or its treatment. Supportive care may include the following: - Transfusion therapy Transfusion therapy (blood transfusion) is a method of giving red blood cells, white blood cells, or platelets to replace blood cells destroyed by disease or treatment. A red blood cell transfusion is given when the red blood cell count is low and signs or symptoms of anemia, such as shortness of breath or feeling very tired, occur. A platelet transfusion is usually given when the patient is bleeding, is having a procedure that may cause bleeding, or when the platelet count is very low. Patients who receive many blood cell transfusions may have tissue and organ damage caused by the buildup of extra iron. These patients may be treated with iron chelation therapy to remove the extra iron from the blood. - Erythropoiesis-stimulating agents Erythropoiesis-stimulating agents (ESAs) may be given to increase the number of mature red blood cells made by the body and to lessen the effects of anemia. Sometimes granulocyte colony-stimulating factor (G-CSF) is given with ESAs to help the treatment work better. - Antibiotic therapy Antibiotics may be given to fight infection. Drug therapy - Lenalidomide Patients with myelodysplastic syndrome associated with an isolated del(5q) chromosome abnormality who need frequent red blood cell transfusions may be treated with lenalidomide. Lenalidomide is used to lessen the need for red blood cell transfusions. - Immunosuppressive therapy Antithymocyte globulin (ATG) works to suppress or weaken the immune system. It is used to lessen the need for red blood cell transfusions. - Azacitidine and decitabine Azacitidine and decitabine are used to treat myelodysplastic syndromes by killing cells that are dividing rapidly. They also help genes that are involved in cell growth to work the way they should. Treatment with azacitidine and decitabine may slow the progression of myelodysplastic syndromes to acute myeloid leukemia. - Chemotherapy used in acute myeloid leukemia (AML) Patients with a myelodysplastic syndrome and a high number of blasts in their bone marrow have a high risk of acute leukemia. They may be treated with the same chemotherapy regimen used in patients with acute myeloid leukemia. Chemotherapy with stem cell transplant Stem cell transplant is a method of giving chemotherapy and replacing blood-forming cells destroyed by the treatment. Stem cells (immature blood cells) are removed from the blood or bone marrow of a donor and are frozen for storage. After the chemotherapy is completed, the stored stem cells are thawed and given back to the patient through an infusion. These reinfused stem cells grow into (and restore) the body's blood cells. This treatment may not work as well in patients whose myelodysplastic syndrome was caused by past treatment for cancer. New types of treatment are being tested in clinical trials. Information about clinical trials is available from the NCI website. Patients may want to think about taking part in a clinical trial. For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment. Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment. Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward. Patients can enter clinical trials before, during, or after starting their treatment. Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment. Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials. Follow-up tests may be needed. Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.

### Question: What are the treatments for Hyperthyroidism ? ### Response:

Health care providers treat hyperthyroidism with medications, radioiodine therapy, or thyroid surgery. The aim of treatment is to bring thyroid hormone levels to a normal state, thus preventing long-term complications, and to relieve uncomfortable symptoms. No single treatment works for everyone. Treatment depends on the cause of hyperthyroidism and how severe it is. When choosing a treatment, health care providers consider a patients age, possible allergies to or side effects of the medications, other conditions such as pregnancy or heart disease, and the availability of an experienced thyroid surgeon. Finding the right specialist for treatment is an important first step. Some professional societies, listed under For More Information, and endocrinology departments in local teaching hospitals can provide the names of local specialists. Medications Beta blockers. Health care providers may prescribe a medication called a beta blocker to reduce symptoms until other treatments take effect. Beta blockers act quickly to relieve many of the symptoms of hyperthyroidism, such as tremors, rapid heartbeat, and nervousness, but do not stop thyroid hormone production. Most people feel better within hours of taking these medications. Antithyroid medications. Antithyroid therapy is the easiest way to treat hyperthyroidism. Antithyroid medications interfere with thyroid hormone production but dont usually have permanent results. Antithyroid medications are not used to treat thyroiditis. Once treatment with antithyroid medications begins, thyroid hormone levels may not move into the normal range for several weeks or months. The average treatment time is about 1 to 2 years, but treatment can continue for many years. Antithyroid medications can cause side effects in some people, including - allergic reactions such as rashes and itching - a decrease in the number of white blood cells in the body, which can lower resistance to infection - liver failure, in rare cases Stop your antithyroid medication and call your health care provider right away if you develop any of the following while taking antithyroid medications: - fatigue - weakness - vague abdominal pain - loss of appetite - skin rash or itching - easy bruising - yellowing of the skin or whites of the eyes, called jaundice - persistent sore throat - fever In the United States, health care providers prescribe the antithyroid medication methimazole (Tapazole, Northyx) for most types of hyperthyroidism. Antithyroid medications and pregnancy. Because pregnant and breastfeeding women cannot receive radioiodine therapy, they are usually treated with an antithyroid medication instead. However, experts agree that women in their first trimester of pregnancy should not take methimazole due to the rare occurrence of damage to the fetus. Another antithyroid medication, propylthiouracil (PTU), is available for women in this stage of pregnancy or for women who are allergic to or intolerant of methimazole and have no other treatment options. Health care providers may prescribe PTU for the first trimester of pregnancy and switch to methimazole for the second and third trimesters. Some women are able to stop taking antithyroid medications in the last 4 to 8 weeks of pregnancy due to the remission of hyperthyroidism that occurs during pregnancy. However these women should continue to be monitored for recurrence of thyroid problems following delivery. Studies have shown that mothers taking antithyroid medications may safely breastfeed. However, they should take only moderate doses, less than 1020 milligrams daily, of the antithyroid medication methimazole. Doses should be divided and taken after feedings, and the infants should be monitored for side effects.4 Women requiring higher doses of the antithyroid medication to control hyperthyroidism should not breastfeed. Radioiodine Therapy Radioactive iodine-131 is a common and effective treatment for hyperthyroidism. In radioiodine therapy, patients take radioactive iodine-131 by mouth. Because the thyroid gland collects iodine to make thyroid hormone, it will collect the radioactive iodine from the bloodstream in the same way. The radioactive iodine gradually destroys the cells that make up the thyroid gland but does not affect other body tissues. More than one round of radioiodine therapy may be needed to bring thyroid hormone production into the normal range. In the meantime, treatment with beta blockers can control symptoms. Almost everyone who receives radioactive iodine treatment eventually develops hypothyroidism. But health care providers consider this an acceptable outcome because hypothyroidism is easier to treat and has fewer long-term complications than hyperthyroidism. People who develop hypothyroidism must take synthetic thyroid hormone. Radioiodine and pregnancy. Although iodine-131 is not known to cause birth defects or infertility, radioiodine therapy is not used in pregnant women or women who are breastfeeding. Radioactive iodine can be harmful to the fetus thyroid and can be passed from mother to child in breast milk. Experts recommend that women wait a year after treatment before becoming pregnant. Thyroid Surgery The least-used treatment is surgery to remove part or most of the thyroid gland. Sometimes surgery may be used to treat - pregnant women who cannot tolerate antithyroid medications - people with large goiters - people who have cancerous thyroid nodules, though hyperthyroidism does not cause cancer Before surgery, the health care provider may prescribe antithyroid medications to temporarily bring a patients thyroid hormone levels into the normal range. This presurgical treatment prevents a condition called thyroid storma sudden, severe worsening of symptomsthat can occur when hyperthyroid patients have general anesthesia. When part of the thyroid is removedas a treatment for toxic nodules, for examplethyroid hormone levels may return to normal. But some surgical patients may still develop hypothyroidism and need to take synthetic thyroxine, a medication that is identical to the hormone, T4, made by the thyroid. If the entire thyroid is removed, lifelong thyroid hormone medication is necessary. After surgery, health care providers will continue to monitor patients thyroid hormone levels. Although uncommon, certain problems can occur in thyroid surgery. The parathyroid glands can be damaged because they are located very close to the thyroid. These glands help control calcium and phosphorus levels in the body. Damage to the laryngeal nerve, also located close to the thyroid, can lead to voice changes or breathing problems. But when surgery is performed by an experienced surgeon, less than 1 percent of patients have permanent complications.5 People who need help finding a surgeon can contact one of the organizations listed under For More Information.

### Question: What is (are) Renal Tubular Acidosis ? ### Response:

Type 1: Classical Distal RTA Type 1 is also called classical distal RTA. "Distal," which means distant, refers to the point in the urine-forming tube of the kidney where the defect occursrelatively distant from the point where fluid from the blood enters the tiny tube, or tubule, that collects fluid and wastes to form urine. This disorder may be inherited as a primary disorder or may be one symptom of a disease that affects many parts of the body. Researchers have discovered abnormal genes responsible for the inherited forms of the disease. More often, however, classical distal RTA occurs as a result of systemic diseasesdiseases that affect many organ systemslike the autoimmune disorders Sjgren's syndrome and lupus, which also attack the distal tubule. Other diseases and conditions associated with classical distal RTA include sickle cell anemia, hyperparathyroidism, hyperthyroidism, chronic active hepatitis, primary biliary cirrhosis, a hereditary form of deafness, analgesic nephropathy, rejection of a transplanted kidney, renal medullary cystic disease, obstructive uropathy, and chronic urinary tract infections. Many of these conditions cause abnormal calcium deposits to build up in the kidney and impair distal tubule function. A major consequence of classical distal RTA is a low blood potassium level. The level drops if the kidneys excrete too much potassium into urine instead of returning it to the blood supply. Because potassium helps regulate nerve and muscle health and heart rate, low levels can cause extreme weakness, irregular heartbeat, paralysis, and even death. Untreated classical distal RTA causes growth retardation in children and progressive kidney and bone disease in adults. Restoring normal growth and preventing kidney stones are the major goals of therapy. If acidosis is corrected with sodium bicarbonate or sodium citrate, then low blood-potassium, salt depletion, and calcium leakage into urine will be corrected. This alkali therapy also helps decrease the development of kidney stones and stabilizes kidney function so kidney failure does not progress. Infants may need potassium supplements, but older children and adults rarely do because alkali therapy prevents the kidney from excreting potassium into the urine. Type 2: Proximal RTA Type 2 is also called proximal RTA. The word "proximal," which means near, indicates that the defect is closer to the point where fluid and wastes from the blood enter the tubule. This form of RTA occurs most frequently in children as part of a disorder called Fanconi's syndrome. The features of Fanconi's syndrome include the abnormal excretion of glucose, amino acids, citrate, and phosphate into the urine, as well as vitamin D deficiency and low blood-potassium. Proximal RTA can also result from inherited disorders that disrupt the body's normal breakdown and use of nutrients. Examples include the rare disease cystinosis, in which cystine crystals are deposited in bones and other tissues; hereditary fructose intolerance; and Wilson disease. Proximal RTA also occurs in patients treated with ifosfamide, a drug used in chemotherapy. A few older drugssuch as acetazolamide or outdated tetracyclinecan also cause proximal RTA. In adults, proximal RTA may complicate diseases like multiple myeloma, or it may occur in people who experience chronic rejection of a transplanted kidney. When possible, identifying and correcting the underlying causes are important steps in treating the acquired forms of proximal RTA. The diagnosis is based on the chemical analysis of blood and urine samples. Children with this disorder would likely receive large doses of an oral alkali, such as sodium bicarbonate or potassium citrate, to treat acidosis and prevent bone disorders, kidney stones, and growth failure. Correcting acidosis and low potassium levels restores normal growth patterns, allowing bone to mature while preventing further renal disease. Vitamin D supplements may also be needed to help prevent bone problems. Type 3 Type 3 is rarely used as a classification because it is now thought to be a combination of type 1 and type 2. Type 4: Hyperkalemic RTA Type 4 is also called hyperkalemic RTA and is caused by a generalized transport abnormality of the distal tubule. The transport of electrolytes such as sodium, chloride, and potassium that normally occurs in the distal tubule is impaired. This form is distinguished from classical distal RTA and proximal RTA because it results in high levels of potassium in the blood instead of low levels. Either low potassiumhypokalemiaor high potassiumhyperkalemiacan be a problem because potassium is important in regulating heart rate. Type 4 RTA occurs when blood levels of the hormone aldosterone are low or when the kidneys do not respond to it. Aldosterone directs the kidneys to regulate the levels of sodium, potassium, and chloride in the blood. Type 4 RTA also occurs when the tubule transport of electrolytes such as sodium, chloride, and potassium is impaired due to an inherited disorder or the use of certain drugs. Drugs that may cause type 4 RTA include - diuretics used to treat congestive heart failure such as spironolactone or eplerenone - blood pressure drugs called angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) - the antibiotic trimethoprim - the antibiotic pentamidine, which is used to treat pneumonia - an agent called heparin that keeps blood from clotting - a class of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs) - some immunosuppressive drugs used to prevent rejection Type 4 RTA may also result from diseases that alter kidney structure and function such as diabetic nephropathy, HIV/AIDS, Addison's disease, sickle cell disease, urinary tract obstruction, lupus, amyloidosis, removal or destruction of both adrenal glands, and kidney transplant rejection. For people who produce aldosterone but cannot use it, researchers have identified the genetic basis for their body's resistance to the hormone. To treat type 4 RTA successfully, patients may require alkaline agents to correct acidosis and medication to lower the potassium in their blood. If treated early, most people with any type of RTA will not develop permanent kidney failure. Therefore, the goal is early recognition and adequate therapy, which will need to be maintained and monitored throughout the person's lifetime.

### Question: What causes Gout ? ### Response:

A Buildup of Uric Acid Most people with gout have too much uric acid in their blood, a condition called hyperuricemia. Uric acid is a substance that results from the breakdown of purines which are a part of all human tissue and found in many foods. Needle-like crystals of uric acid can build up in the connective tissue, in the joint space between two bones, or both. If too many uric acid crystals form as a result of hyperuricemia, gout can develop. Risk Factors These risk factors are associated with gout. - Genetics. Many people with gout have a family history of the disease. Genetics. Many people with gout have a family history of the disease. - Gender and age. Gout is more common in men than in women and more common in adults than in children. Gender and age. Gout is more common in men than in women and more common in adults than in children. - Weight. Being overweight increases the risk of developing gout because there is more tissue available for turnover or breakdown, which leads to excess uric acid production. Weight.

Renal insufficiency, or the inability of the kidneys to eliminate waste products, is a common cause of gout in older people. Other medical problems that contribute to high blood levels of uric acid include - high blood pressure - hypothyroidism (underactive thyroid gland) - conditions that cause an excessively rapid turnover of cells, such as psoriasis, hemolytic anemia, or some cancers - Kelley-Seegmiller syndrome or Lesch-Nyhan syndrome, two rare conditions in which the enzyme that helps control uric acid levels either is not present or is found in insufficient quantities.

### Question: What are the treatments for Heart Attack ? ### Response:

Heart attacks are a leading killer of both men and women in the United States. The good news is that excellent treatments are available for heart attacks. These treatments can save lives and prevent disabilities. Heart attack treatment works best when it's given right after symptoms occur. Act Fast The signs and symptoms of a heart attack can develop suddenly. However, they also can develop slowlysometimes within hours, days, or weeks of a heart attack. Know the warning signs of a heart attack so you can act fast to get treatment for yourself or someone else. The sooner you get emergency help, the less damage your heart will sustain. Call 911 for an ambulance right away if you think you or someone else may be having a heart attack. You also should call for help if your chest pain doesn't go away as it usually does when you take medicine prescribed for angina. Treatment May Start Right Away Treatment for a heart attack may begin in the ambulance or in the emergency department and continue in a special area of the hospital called a coronary care unit. Do not drive to the hospital or let someone else drive you. Call an ambulance so that medical personnel can begin life-saving treatment on the way to the emergency room. Restoring Blood Flow to the Heart The coronary care unit is specially equipped with monitors that continuously monitor your vital signs. These include - an EKG which detects any heart rhythm problems - a blood pressure monitor, and - pulse oximetry, which measures the amount of oxygen in the blood. an EKG which detects any heart rhythm problems a blood pressure monitor, and pulse oximetry, which measures the amount of oxygen in the blood. In the hospital, if you have had or are having a heart attack, doctors will work quickly to restore blood flow to your heart and continuously monitor your vital signs to detect and treat complications. Restoring blood flow to the heart can prevent or limit damage to the heart muscle and help prevent another heart attack. Doctors may use clot-busting drugs called thrombolytics and procedures such as angioplasty. - Clot-busters or thrombolytic drugs are used to dissolve blood clots that are blocking blood flow to the heart. When given soon after a heart attack begins, these drugs can limit or prevent permanent damage to the heart. To be most effective, these drugs must be given within one hour after the start of heart attack symptoms. - Angioplasty procedures are used to open blocked or narrowed coronary arteries. A stent, which is a tiny metal mesh tube, may be placed in the artery to help keep it open. Some stents are coated with medicines that help prevent the artery from becoming blocked again. - Coronary artery bypass surgery uses arteries or veins from other areas in your body to bypass your blocked coronary arteries.

Coronary artery bypass surgery uses arteries or veins from other areas in your body to bypass your blocked coronary arteries. Drug Treatments Many medications are used to treat heart attacks. They include beta blockers, ACE inhibitors, nitrates, anticoagulants, antiplatelet medications, and medications to relieve pain and anxiety. - Beta blockers slow your heart rate and reduce your heart's need for blood and oxygen. As a result, your heart beats with less force, and your blood pressure falls. Beta blockers are also used to relieve angina and prevent second heart attacks and correct an irregular heartbeat. - Angiotensin-converting enzyme or ACE inhibitors lower your blood pressure and reduce the strain on your heart. They are used in some patients after a heart attack to help prevent further weakening of the heart and increase the chances of survival. - Nitrates, such as nitroglycerin, relax blood vessels and relieve chest pain. Anticoagulants, such as heparin and warfarin, thin the blood and prevent clots from forming in your arteries. - >Antiplatelet medications, such as aspirin and clopidogrel, stop platelets from clumping together to form clots. They are given to people who have had a heart attack, have angina, or have had an angioplasty. - Glycoprotein llb-llla inhibitors are potent antiplatelet medications given intravenously to prevent clots from forming in your arteries.

Glycoprotein llb-llla inhibitors are potent antiplatelet medications given intravenously to prevent clots from forming in your arteries. Doctors may also prescribe medications to relieve pain and anxiety, or to treat irregular heart rhythms which often occur during a heart attack. Echocardiogram and Stress Tests While you are still in the hospital or after you go home, your doctor may order other tests, such as an echocardiogram. An echocardiogram uses ultrasound to make an image of the heart which can be seen on a video monitor. It shows how well the heart is filling with blood and pumping it to the rest of the body. Your doctor may also order a stress test to see how well your heart works when it has a heavy workload. You run on a treadmill or pedal a bicycle or receive medicine through a vein in your arm to make your heart work harder. EKG and blood pressure readings are taken before, during, and after the test to see how your heart responds. Often, an echocardiogram or nuclear scan of the heart is performed before and after exercise or intravenous medication. The test is stopped if chest pain or a very sharp rise or fall in blood pressure occurs. Monitoring continues for 10 to 15 minutes after the test or until your heart rate returns to baseline.

### Question: What to do for Hypoglycemia ? ### Response:

Two types of hypoglycemia can occur in people who do not have diabetes: - Reactive hypoglycemia, also called postprandial hypoglycemia, occurs within 4 hours after meals. - Fasting hypoglycemia, also called postabsorptive hypoglycemia, is often related to an underlying disease. Symptoms of both reactive and fasting hypoglycemia are similar to diabetes-related hypoglycemia. Symptoms may include hunger, sweating, shakiness, dizziness, light-headedness, sleepiness, confusion, difficulty speaking, anxiety, and weakness. To find the cause of a patient's hypoglycemia, the doctor will use laboratory tests to measure blood glucose, insulin, and other chemicals that play a part in the body's use of energy. Reactive Hypoglycemia Diagnosis To diagnose reactive hypoglycemia, the doctor may - ask about signs and symptoms - test blood glucose while the patient is having symptoms by taking a blood sample from the arm and sending it to a laboratory for analysis* - check to see whether the symptoms ease after the patient's blood glucose returns to 70 mg/dL or above after eating or drinking A blood glucose level below 70 mg/dL at the time of symptoms and relief after eating will confirm the diagnosis. The oral glucose tolerance test is no longer used to diagnose reactive hypoglycemia because experts now know the test can actually trigger hypoglycemic symptoms. Causes and Treatment The causes of most cases of reactive hypoglycemia are still open to debate. Some researchers suggest that certain people may be more sensitive to the body's normal release of the hormone epinephrine, which causes many of the symptoms of hypoglycemia. Others believe deficiencies in glucagon secretion might lead to reactive hypoglycemia. A few causes of reactive hypoglycemia are certain, but they are uncommon. Gastricor stomachsurgery can cause reactive hypoglycemia because of the rapid passage of food into the small intestine. Rare enzyme deficiencies diagnosed early in life, such as hereditary fructose intolerance, also may cause reactive hypoglycemia. To relieve reactive hypoglycemia, some health professionals recommend - eating small meals and snacks about every 3 hours - being physically active - eating a variety of foods, including meat, poultry, fish, or nonmeat sources of protein; starchy foods such as whole-grain bread, rice, and potatoes; fruits; vegetables; and dairy products - eating foods high in fiber - avoiding or limiting foods high in sugar, especially on an empty stomach The doctor can refer patients to a registered dietitian for personalized meal planning advice. Although some health professionals recommend a diet high in protein and low in carbohydrates, studies have not proven the effectiveness of this kind of diet to treat reactive hypoglycemia. Fasting Hypoglycemia Diagnosis Fasting hypoglycemia is diagnosed from a blood sample that shows a blood glucose level below 50 mg/dL after an overnight fast, between meals, or after physical activity. Causes and Treatment Causes of fasting hypoglycemia include certain medications, alcoholic beverages, critical illnesses, hormonal deficiencies, some kinds of tumors, and certain conditions occurring in infancy and childhood. Medications. Medications, including some used to treat diabetes, are the most common cause of hypoglycemia. Other medications that can cause hypoglycemia include - salicylates, including aspirin, when taken in large doses - sulfa medications, which are used to treat bacterial infections - pentamidine, which treats a serious kind of pneumonia - quinine, which is used to treat malaria If using any of these medications causes a person's blood glucose level to fall, the doctor may advise stopping the medication or changing the dose. Alcoholic beverages. Drinking alcoholic beverages, especially binge drinking, can cause hypoglycemia. The body's breakdown of alcohol interferes with the liver's efforts to raise blood glucose. Hypoglycemia caused by excessive drinking can be serious and even fatal. Critical illnesses. Some illnesses that affect the liver, heart, or kidneys can cause hypoglycemia. Sepsis, which is an overwhelming infection, and starvation are other causes of hypoglycemia. In these cases, treating the illness or other underlying cause will correct the hypoglycemia. Hormonal deficiencies. Hormonal deficiencies may cause hypoglycemia in very young children, but rarely in adults. Shortages of cortisol, growth hormone, glucagon, or epinephrine can lead to fasting hypoglycemia. Laboratory tests for hormone levels will determine a diagnosis and treatment. Hormone replacement therapy may be advised. Tumors. Insulinomas are insulin-producing tumors in the pancreas. Insulinomas can cause hypoglycemia by raising insulin levels too high in relation to the blood glucose level. These tumors are rare and do not normally spread to other parts of the body. Laboratory tests can pinpoint the exact cause. Treatment involves both short-term steps to correct the hypoglycemia and medical or surgical measures to remove the tumor. Conditions occurring in infancy and childhood. Children rarely develop hypoglycemia. If they do, causes may include the following: - Brief intolerance to fasting, often during an illness that disturbs regular eating patterns. Children usually outgrow this tendency by age 10. - Hyperinsulinism, which is the overproduction of insulin. This condition can result in temporary hypoglycemia in newborns, which is common in infants of mothers with diabetes. Persistent hyperinsulinism in infants or children is a complex disorder that requires prompt evaluation and treatment by a specialist. - Enzyme deficiencies that affect carbohydrate metabolism. These deficiencies can interfere with the body's ability to process natural sugars, such as fructose and galactose, glycogen, or other metabolites. - Hormonal deficiencies such as lack of pituitary or adrenal hormones. *A personal blood glucose monitor cannot be used to diagnose reactive hypoglycemia.

### Question: What are the symptoms of Schwartz Jampel syndrome type 1 ? ### Response:

What are the signs and symptoms of Schwartz Jampel syndrome type 1? Individuals with Schwartz-Jampel syndrome type 1 (SJS1) have characteristic facial features, muscle weakness (hypotonia), and muscle stiffness (myotonia). Facial features of individuals with SJS1 can seem "fixed" in the same expression with puckered lips due to weakening and stiffening of the facial muscles. Additional facial features may include: Blepharophimosis (narrowing of the eye opening) Epicanthal folds (skin fold of the upper eyelid covering the inner corner of the eye) Blepharospasm (involuntary blinking or spasm of the eyelids) Hypertrichosis (excessive hair) of the eye lashes Micrognathia (small lower jaw) Individuals with SJS1 usually have short stature. Other skeletal and joint findings may include: Shortened neck Pectus carinatum (outward bowing of the chest) Kyphosis (curving of the spine that causes a bowing or rounding of the back) Coxa valga (hip deformity involving an increased neck-shaft angle of the femur) Joint contractures Osteoporosis Widening of the metaphysis (portion of the bone containing the growth plate) Delayed bone age Other less common symptoms include: a high pitched voice, bilateral carpel tunnel syndrome, and malignant hyperthermia. One study suggested that as many as 20% of individuals with SJS1 have an intellectual disability; however, most individuals with SJS1 have normal intelligence. The Human Phenotype Ontology provides the following list of signs and symptoms for Schwartz Jampel syndrome type 1. If the information is available, the table below includes how often the symptom is seen in people with this 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 prevent Oral Cavity and Oropharyngeal Cancer ? ### Response:

Key Points - Avoiding risk factors and increasing protective factors may help prevent cancer. - The following are risk factors for oral cavity cancer and oropharyngeal cancer: - Tobacco use - Alcohol use - Tobacco and alcohol use - Betel quid or gutka chewing - Personal history of head and neck cancer - The following is a risk factor for oropharyngeal cancer: - HPV infection - The following is a protective factor for oral cavity cancer and oropharyngeal cancer: - Quitting smoking - It is not clear whether avoiding certain risk factors will decrease the risk of oral cavity cancer or oropharyngeal cancer. - Cancer prevention clinical trials are used to study ways to prevent cancer. - New ways to prevent oral cavity cancer and oropharyngeal cancer are being studied in clinical trials. Avoiding risk factors and increasing protective factors may help prevent cancer. Avoiding cancer risk factors may help prevent certain cancers. Risk factors include smoking, being overweight, and not getting enough exercise. Increasing protective factors such as quitting smoking and exercising may also help prevent some cancers. Talk to your doctor or other health care professional about how you might lower your risk of cancer. Oral cavity cancer and oropharyngeal cancer are two different diseases, but they have some risk factors in common. The following are risk factors for oral cavity cancer and oropharyngeal cancer: Tobacco use Using tobacco is the most common cause of oral cavity cancer and oropharyngeal cancer. The risk of these cancers is about 5 to 10 times higher for current smokers than for people who have never smoked. The use of all types of tobacco, including cigarettes, pipes, cigars, and smokeless tobacco (snuff and chewing tobacco) can cause cancer of the oral cavity and oropharynx. For cigarette smokers, the risk of oral cavity cancer and oropharyngeal cancer increases with the number of cigarettes smoked per day. Alcohol use Using alcohol is also an important risk factor for oral cavity cancer and oropharyngeal cancer. The risk of oral cavity cancer and oropharyngeal cancer increases with the number of alcoholic drinks consumed per day. The risk of oral cavity cancer and oropharyngeal cancer is about twice as high in people who have 3 to 4 alcoholic drinks per day and 5 times higher in people who have 5 or more alcoholic drinks per day compared with those who don't drink alcohol. Tobacco and alcohol use The risk of oral cavity cancer and oropharyngeal cancer is 2 to 3 times higher in people who use both tobacco and alcohol than it is in people who use only tobacco or only alcohol. The risk of oral cavity cancer and oropharyngeal cancer is about 35 times higher in people who smoke 2 or more packs of cigarettes per day and have more than 4 alcoholic drinks per day than it is in people who have never smoked cigarettes or consumed alcohol. Betel quid or gutka chewing Chewing betel quid or gutka (betel quid mixed with tobacco) has been shown to increase the risk of oral cavity cancer and oropharyngeal cancer. Betel quid contains areca nut, which is a cancer-causing substance. The risk of oral cavity cancer and oropharyngeal cancer increases with how long and how often betel quid or gutka are chewed. The risk for oral cavity cancer and oropharyngeal cancer is higher when chewing gutka than when chewing betel quid alone. Betel quid and gutka chewing is common in many countries in South Asia and Southeast Asia, including China and India. Personal history of head and neck cancer A personal history of head and neck cancer increases the risk of oral cavity cancer and oropharyngeal cancer. The following is a risk factor for oropharyngeal cancer: HPV infection Being infected with certain types of HPV, especially HPV type 16, increases the risk of oropharyngeal cancer. HPV infection is spread mainly through sexual contact. The risk of oropharyngeal cancer is about 15 times higher in people who have oral HPV 16 infection compared with people who do not have oral HPV 16 infection. The following is a protective factor for oral cavity cancer and oropharyngeal cancer: Quitting smoking Studies have shown that when people stop smoking cigarettes, their risk of oral cavity cancer and oropharyngeal cancer decreases by one half (50%) within 5 years. Within 20 years of quitting, their risk of oral cavity cancer and oropharyngeal cancer is the same as for a person who never smoked cigarettes. It is not clear whether avoiding certain risk factors will decrease the risk of oral cavity cancer or oropharyngeal cancer. It has not been proven that stopping alcohol use will decrease the risk of oral cavity cancer or oropharyngeal cancer. Getting an HPV vaccination greatly lessens the risk of oral HPV infection. It is not yet known whether getting an HPV vaccination at any age will decrease the risk of oropharyngeal cancer from HPV infection. Cancer prevention clinical trials are used to study ways to prevent cancer. Cancer prevention clinical trials are used to study ways to lower the risk of certain types of cancer. Some cancer prevention trials are done with healthy people who have not had cancer but who have an increased risk for cancer. Other prevention trials are done with people who have had cancer and are trying to prevent another cancer of the same type or to lower their chance of developing a new type of cancer. Other trials are done with healthy volunteers who are not known to have any risk factors for cancer. The purpose of some cancer prevention clinical trials is to find out whether actions people take can prevent cancer. These may include eating fruits and vegetables, exercising, quitting smoking, or taking certain medicines, vitamins, minerals, or food supplements. New ways to prevent oral cavity cancer and oropharyngeal cancer are being studied in clinical trials. Clinical trials are taking place in many parts of the country. Information about clinical trials can be found in the Clinical Trials section of the NCI website. Check NCI's list of cancer clinical trials for oral cavity cancer prevention trials and oropharyngeal cancer prevention trials that are now accepting patients.

### Question: What is (are) Childhood Acute Myeloid Leukemia and Other Myeloid Malignancies ? ### Response:

Key Points - Childhood acute myeloid leukemia (AML) is a type of cancer in which the bone marrow makes a large number of abnormal blood cells. - Leukemia and other diseases of the blood and bone marrow may affect red blood cells, white blood cells, and platelets. - Other myeloid diseases can affect the blood and bone marrow. - Chronic myelogenous leukemia - Juvenile myelomonocytic leukemia - Myelodysplastic syndromes - AML or MDS may occur after treatment with certain anticancer drugs and/or radiation therapy. - The risk factors for childhood AML, childhood CML, JMML, and MDS are similar. - Signs and symptoms of childhood AML, childhood CML, JMML, or MDS include fever, feeling tired, and easy bleeding or bruising. - Tests that examine the blood and bone marrow are used to detect (find) and diagnose childhood AML, childhood CML, JMML, and MDS. - Certain factors affect prognosis (chance of recovery) and treatment options. Childhood acute myeloid leukemia (AML) is a type of cancer in which the bone marrow makes a large number of abnormal blood cells. Childhood acute myeloid leukemia (AML) is a cancer of the blood and bone marrow. AML is also called acute myelogenous leukemia, acute myeloblastic leukemia, acute granulocytic leukemia, and acute nonlymphocytic leukemia. Cancers that are acute usually get worse quickly if they are not treated. Cancers that are chronic usually get worse slowly. Leukemia and other diseases of the blood and bone marrow may affect red blood cells, white blood cells, and platelets. Normally, the bone marrow makes blood stem cells (immature cells) that become mature blood cells over time. A blood stem cell may become a myeloid stem cell or a lymphoid stem cell. A lymphoid stem cell becomes a white blood cell. A myeloid stem cell becomes one of three types of mature blood cells: - Red blood cells that carry oxygen and other substances to all tissues of the body. - White blood cells that fight infection and disease. - Platelets that form blood clots to stop bleeding. In AML, the myeloid stem cells usually become a type of immature white blood cell called myeloblasts (or myeloid blasts). The myeloblasts, or leukemia cells, in AML are abnormal and do not become healthy white blood cells. The leukemia cells can build up in the blood and bone marrow so there is less room for healthy white blood cells, red blood cells, and platelets. When this happens, infection, anemia, or easy bleeding may occur. The leukemia cells can spread outside the blood to other parts of the body, including the central nervous system (brain and spinal cord), skin, and gums. Sometimes leukemia cells form a solid tumor called a granulocytic sarcoma or chloroma. There are subtypes of AML based on the type of blood cell that is affected. The treatment of AML is different when it is a subtype called acute promyelocytic leukemia (APL) or when the child has Down syndrome. Other myeloid diseases can affect the blood and bone marrow. Chronic myelogenous leukemia In chronic myelogenous leukemia (CML), too many bone marrow stem cells become a type of white blood cell called granulocytes. Some of these bone marrow stem cells never become mature white blood cells. These are called blasts. Over time, the granulocytes and blasts crowd out the red blood cells and platelets in the bone marrow. CML is rare in children. Juvenile myelomonocytic leukemia Juvenile myelomonocytic leukemia (JMML) is a rare childhood cancer that occurs more often in children around the age of 2 years and is more common in boys. In JMML, too many bone marrow stem cells become 2 types of white blood cells called myelocytes and monocytes. Some of these bone marrow stem cells never become mature white blood cells. These immature cells, called blasts, are unable to do their usual work. Over time, the myelocytes, monocytes, and blasts crowd out the red blood cells and platelets in the bone marrow. When this happens, infection, anemia, or easy bleeding may occur. Myelodysplastic syndromes Myelodysplastic syndromes (MDS) occur less often in children than in adults. In MDS, the bone marrow makes too few red blood cells, white blood cells, and platelets. These blood cells may not mature and enter the blood. The treatment for MDS depends on how low the numbers of red blood cells, white blood cells, or platelets are. Over time, MDS may become AML. Transient myeloproliferative disorder (TMD) is a type of MDS. This disorder of the bone marrow can develop in newborns who have Down syndrome. It usually goes away on its own within the first 3 weeks of life. Infants who have Down syndrome and TMD have an increased chance of developing AML before the age of 3 years. This summary is about childhood AML, childhood CML, JMML, and MDS. See the following PDQ summaries for more information about other types of leukemia and diseases of the blood and bone marrow in children and adults: - Childhood Acute Lymphoblastic Leukemia Treatment - Adult Acute Myeloid Leukemia Treatment - Adult Acute Lymphoblastic Leukemia Treatment - Chronic Myelogenous Leukemia Treatment - Chronic Lymphocytic Leukemia Treatment - Hairy Cell Leukemia Treatment - Myelodysplastic Syndromes Treatment - Myelodysplastic/Myeloproliferative Neoplasms Treatment AML or MDS may occur after treatment with certain anticancer drugs and/or radiation therapy. Cancer treatment with certain anticancer drugs and/or radiation therapy may cause therapy -related AML (t-AML) or therapy-related MDS (t-MDS). The risk of these therapy-related myeloid diseases depends on the total dose of the anticancer drugs used and the radiation dose and treatment field. Some patients also have an inherited risk for t-AML and t-MDS. These therapy-related diseases usually occur within 7 years after treatment, but are rare in children.

### Question: What are the treatments for Acromegaly ? ### Response:

Currently, treatment options include surgical removal of the tumor, medical therapy, and radiation therapy of the pituitary. Goals of treatment are to - reduce excess hormone production to normal levels - relieve the pressure that the growing pituitary tumor may be exerting on the surrounding brain areas - preserve normal pituitary function or treat hormone deficiencies - improve the symptoms of acromegaly Surgery Surgery is the first option recommended for most people with acromegaly, as it is often a rapid and effective treatment. The surgeon reaches the pituitary via an incision through the nose or inside the upper lip and, with special tools, removes the tumor tissue in a procedure called transsphenoidal surgery. This procedure promptly relieves the pressure on the surrounding brain regions and leads to a rapid lowering of GH levels. If the surgery is successful, facial appearance and soft tissue swelling improve within a few days. Surgery is most successful in patients with blood GH levels below 45 ng/ml before the operation and with pituitary tumors no larger than 10 millimeters (mm) in diameter. Success depends in large part on the skill and experience of the surgeon, as well as the location of the tumor. Even with the most experienced neurosurgeon, the chance of a cure is small if the tumor has extended into critical brain structures or into the cavernous sinus where surgery could be risky. The success rate also depends on what level of GH is defined as a cure. The best measure of surgical success is normalization of GH and IGF-I levels. The overall rate of remission-control of the disease-after surgery ranges from 55 to 80 percent. (See For More Information to locate a board-certified neurosurgeon.) A possible complication of surgery is damage to the surrounding normal pituitary tissue, which requires lifelong use of pituitary hormone replacement. The part of the pituitary that stores antidiuretic hormonea hormone important in water balancemay be temporarily or, rarely, permanently damaged and the patient may require medical therapy. Other potential problems include cerebrospinal fluid leaks and, rarely, meningitis. Cerebrospinal fluid bathes the brain and can leak from the nose if the incision area doesnt heal well. Meningitis is a bacterial or viral infection of the meninges, the outer covering of the brain. Even when surgery is successful and hormone levels return to normal, people with acromegaly must be carefully monitored for years for possible recurrence of the disease. More commonly, hormone levels improve, but do not return to normal. Additional treatment, usually medications, may be required. Medical Therapy Medical therapy is most often used if surgery does not result in a cure and sometimes to shrink large tumors before surgery. Three medication groups are used to treat acromegaly. Somatostatin analogs (SSAs) are the first medication group used to treat acromegaly. They shut off GH production and are effective in lowering GH and IGF-I levels in 50 to 70 percent of patients. SSAs also reduce tumor size in around 0 to 50 percent of patients but only to a modest degree. Several studies have shown that SSAs are safe and effective for long-term treatment and in treating patients with acromegaly caused by nonpituitary tumors. Long-acting SSAs are given by intramuscular injection once a month. Digestive problems-such as loose stools, nausea, and gas-are a side effect in about half of people taking SSAs. However, the effects are usually temporary and rarely severe. About 10 to 20 percent of patients develop gallstones, but the gallstones do not usually cause symptoms. In rare cases, treatment can result in elevated blood glucose levels. More commonly, SSAs reduce the need for insulin and improve blood glucose control in some people with acromegaly who already have diabetes. The second medication group is the GH receptor antagonists (GHRAs), which interfere with the action of GH. They normalize IGF-I levels in more than 90 percent of patients. They do not, however, lower GH levels. Given once a day through injection, GHRAs are usually well-tolerated by patients. The long-term effects of these drugs on tumor growth are still under study. Side effects can include headaches, fatigue, and abnormal liver function. Dopamine agonists make up the third medication group. These drugs are not as effective as the other medications at lowering GH or IGF-I levels, and they normalize IGF-I levels in only a minority of patients. Dopamine agonists are sometimes effective in patients who have mild degrees of excess GH and have both acromegaly and hyperprolactinemiatoo much of the hormone prolactin. Dopamine agonists can be used in combination with SSAs. Side effects can include nausea, headache, and lightheadedness. Agonist: A drug that binds to a receptor of a cell and triggers a response by the cell, mimicking the action of a naturally occurring substance. Antagonist: A chemical that acts within the body to reduce the physiological activity of another chemical substance or hormone. Radiation Therapy Radiation therapy is usually reserved for people who have some tumor remaining after surgery and do not respond to medications. Because radiation leads to a slow lowering of GH and IGF-I levels, these patients often also receive medication to lower hormone levels. The full effect of this therapy may not occur for many years. The two types of radiation delivery are conventional and stereotactic. Conventional radiation delivery targets the tumor with external beams but can damage surrounding tissue. The treatment delivers small doses of radiation multiple times over 4 to 6 weeks, giving normal tissue time to heal between treatments. Stereotactic delivery allows precise targeting of a high-dose beam of radiation at the tumor from varying angles. The patient must wear a rigid head frame to keep the head still. The types of stereotactic radiation delivery currently available are proton beam, linear accelerator (LINAC), and gamma knife. With stereotactic delivery, the tumor must be at least 5 mm from the optic chiasm to prevent radiation damage. This treatment can sometimes be done in a single session, reducing the risk of damage to surrounding tissue. All forms of radiation therapy cause a gradual decline in production of other pituitary hormones over time, resulting in the need for hormone replacement in most patients. Radiation also can impair a patients fertility. Vision loss and brain injury are rare complications. Rarely, secondary tumors can develop many years later in areas that were in the path of the radiation beam.

### Question: How to diagnose Diagnosis of Diabetes and Prediabetes ? ### Response:

Blood tests are used to diagnosis diabetes and prediabetes because early in the disease type 2 diabetes may have no symptoms. All diabetes blood tests involve drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. Lab analysis of blood is needed to ensure test results are accurate. Glucose measuring devices used in a health care providers office, such as finger-stick devices, are not accurate enough for diagnosis but may be used as a quick indicator of high blood glucose. Testing enables health care providers to find and treat diabetes before complications occur and to find and treat prediabetes, which can delay or prevent type 2 diabetes from developing. Any one of the following tests can be used for diagnosis:* - an A1C test, also called the hemoglobin A1c, HbA1c, or glycohemoglobin test - a fasting plasma glucose (FPG) test - an oral glucose tolerance test (OGTT) *Not all tests are recommended for diagnosing all types of diabetes. See the individual test descriptions for details. Another blood test, the random plasma glucose (RPG) test, is sometimes used to diagnose diabetes during a regular health checkup. If the RPG measures 200 milligrams per deciliter or above, and the individual also shows symptoms of diabetes, then a health care provider may diagnose diabetes. Symptoms of diabetes include - increased urination - increased thirst - unexplained weight loss Other symptoms can include fatigue, blurred vision, increased hunger, and sores that do not heal. Any test used to diagnose diabetes requires confirmation with a second measurement unless clear symptoms of diabetes exist. The following table provides the blood test levels for diagnosis of diabetes for nonpregnant adults and diagnosis of prediabetes. A1C Test The A1C test is used to detect type 2 diabetes and prediabetes but is not recommended for diagnosis of type 1 diabetes or gestational diabetes. The A1C test is a blood test that reflects the average of a persons blood glucose levels over the past 3 months and does not show daily fluctuations. The A1C test is more convenient for patients than the traditional glucose tests because it does not require fasting and can be performed at any time of the day. The A1C test result is reported as a percentage. The higher the percentage, the higher a persons blood glucose levels have been. A normal A1C level is below 5.7 percent. An A1C of 5.7 to 6.4 percent indicates prediabetes. People diagnosed with prediabetes may be retested in 1 year. People with an A1C below 5.7 percent maystill be at risk for diabetes, depending on the presence of other characteristics that put them at risk, also known as risk factors. People with an A1C above 6.0 percent should be considered at very high risk of developing diabetes. A level of 6.5 percent or above means a person has diabetes. Laboratory analysis. When the A1C test is used for diagnosis, the blood sample must be sent to a laboratory using a method that is certified by the NGSP to ensure the results are standardized. Blood samples analyzed in a health care providers office, known as point-of-care tests, are not standardized for diagnosing diabetes. Abnormal results. The A1C test can be unreliable for diagnosing or monitoring diabetes in people with certain conditions known to interfere with the results. Interference should be suspected when A1C results seem very different from the results of a blood glucose test. People of African, Mediterranean, or Southeast Asian descent or people with family members with sickle cell anemia or a thalassemia are particularly at risk of interference. However, not all of the A1C tests are unreliable for people with these diseases. The NGSP provides information about which A1C tests are appropriate to use for specific types of interference and details on any problems with the A1C test at www.ngsp.org. False A1C test results may also occur in people with other problems that affect their blood or hemoglobin such as chronic kidney disease, liver disease, or anemia. More information about limitations of the A1C test and different forms of sickle cell anemia is provided in the NIDDK health topic, For People of African, Mediterranean, or Southeast Asian Heritage: Important Information about Diabetes Blood Tests, or by calling 18008608747. Changes in Diagnostic Testing In the past, the A1C test was used to monitor blood glucose levels but not for diagnosis. The A1C test has now been standardized, and in 2009, an international expert committee recommended it be used for diagnosis of type 2 diabetes and prediabetes.2 More information about the A1C test is provided in the NIDDK health topic, The A1C Test and Diabetes, or by calling 18008608747. Fasting Plasma Glucose Test The FPG test is used to detect diabetes and prediabetes. The FPG test has been the most common test used for diagnosing diabetes because it is more convenient than the OGTT and less expensive. The FPG test measures blood glucose in a person who has fasted for at least 8 hours and is most reliable when given in the morning. People with a fasting glucose level of 100 to 125 mg/dL have impaired fasting glucose (IFG), or prediabetes. A level of 126 mg/dL or above, confirmed by repeating the test on another day, means a person has diabetes. Oral Glucose Tolerance Test The OGTT can be used to diagnose diabetes, prediabetes, and gestational diabetes. Research has shown that the OGTT is more sensitive than the FPG test, but it is less convenient to administer. When used to test for diabetes or prediabetes, the OGTT measures blood glucose after a person fasts for at least 8 hours and 2 hours after the person drinks a liquid containing 75 grams of glucose dissolved in water. If the 2-hour blood glucose level is between 140 and 199 mg/dL, the person has a type of prediabetes called impaired glucose tolerance (IGT). If confirmed by a second test, a 2-hour glucose level of 200 mg/dL or above means a person has diabetes.

### Question: How to prevent High Blood Pressure ? ### Response:

Steps You Can Take You can take steps to prevent high blood pressure by adopting these healthy lifestyle habits. - Follow a healthy eating plan. - Be physically active. - Maintain a healthy weight. - If you drink alcoholic beverages, do so in moderation. - Quit smoking. - Learn to cope with and manage stress. Follow a healthy eating plan. Be physically active. Maintain a healthy weight. If you drink alcoholic beverages, do so in moderation. Quit smoking. Learn to cope with and manage stress. Follow a Healthy Eating Plan Follow a healthy eating plan that emphasizes fruits, vegetables, fat-free or low-fat milk and milk products, and whole grains, and that is low in saturated fat, cholesterol, and total fat. Eating this way is even more effective when you also reduce your sodium (salt) intake and calories. One such eating plan is called DASH. DASH stands for Dietary Approaches to Stop Hypertension. This is the name of a study sponsored by the National Institutes of Health that showed that this kind of eating plan can help you prevent and control high blood pressure. The study also showed that combining this kind of eating plan with cutting back on salt in your diet is even more effective at lowering your blood pressure. To learn more about DASH, see Lowering Your Blood Pressure with DASH. Lower Your Salt Intake In general, the lower your salt intake, the lower your blood pressure. Older adults should limit their sodium intake to 2,300 milligrams (mg) daily. The key to reducing the amount of salt we eat is making wise food choices. Only a small amount of the salt that we eat comes from the salt shaker, and only small amounts occur naturally in food. Most of the salt that we eat comes from processed foods -- for example, canned or processed meat, baked goods, certain cereals, soy sauce, and foods that contain seasoned salts, monosodium glutamate (MSG), and baking soda. Food from fast food restaurants, frozen foods, and canned foods also tend to be higher in sodium. See tips to reduce salt in your diet. Read Food Labels Be sure to read food labels to choose products lower in salt. Look for foods and seasonings that are labeled as low-salt or "no added salt." Look for the sodium content in milligrams and the Percent Daily Value. Aim for foods that are less than 5 percent of the Daily Value of sodium. Foods with 20 percent or more Daily Value of sodium are considered high. To learn more about reading nutrition labels, see Reading the Label. Be Physically Active Regular physical activity can lower high blood pressure and reduce your risk for other health problems. Everyone should try to participate in moderate-intensity aerobic exercise at least 2 hours and 30 minutes per week, or vigorous-intensity aerobic exercise for 1 hour and 15 minutes per week. Aerobic exercise, such as brisk walking, is any exercise in which your heart beats harder and you use more oxygen than usual. The more active you are, the more you will benefit. Participate in aerobic exercise for at least 10 minutes at a time, spread throughout the week. (Watch the video to learn how exercise maintains healthy aging.

Most people dont need to see a doctor before they start a moderate-level physical activity. You should check first with your doctor if you - have heart trouble or have had a heart attack - are over age 50 and are not used to moderate-level physical activity - have a family history of heart disease at an early age, or if you have any other serious health problem. have heart trouble or have had a heart attack are over age 50 and are not used to moderate-level physical activity have a family history of heart disease at an early age, or if you have any other serious health problem. See examples of exercises for older adults at Exercises to Try. For more on exercise and physical activity for older adults, visit Go4Life, the exercise and physical activity campaign from the National Institute on Aging. Maintain a Healthy Weight Maintaining a healthy weight can help you control high blood pressure and reduce your risk for other health problems. Blood pressure rises as body weight increases. Losing even 10 pounds can lower blood pressure -- and it has the greatest effect for those who are overweight and already have hypertension. A useful measure of overweight and obesity is body mass index (BMI). BMI measures your weight in relation to your height. See the BMI calculator to determine your body mass index or talk to your health care provider. A BMI - below 18.5 is a sign that you are underweight. - between 18.5 and 24.9 is in the healthy range. - between 25 and 29.9 is considered overweight. - of 30 or more is considered obese. below 18.5 is a sign that you are underweight. between 18.5 and 24.9 is in the healthy range. between 25 and 29.9 is considered overweight. of 30 or more is considered obese. A general goal to aim for is a BMI below 25. Your health care provider can help you set an appropriate BMI goal. Measuring waist circumference helps screen for possible health risks. If most of your fat is around your waist rather than at your hips, youre at a higher risk for heart disease and type 2 diabetes. This risk may be high with a waist size that is greater than 35 inches for women or greater than 40 inches for men. To learn how to measure your waist, visit Assessing Your Weight and Health Risk. For more information about losing weight or maintaining your weight, see Aim for a Healthy Weight. If You Drink Drinking too much alcohol can raise your blood pressure. Alcohol also adds extra calories, which may cause weight gain. Men should have no more than two drinks a day, and women should have no more than one drink a day. If you drink and would like tips on how to cut back, watch the video "How To Cut Back on Your Drinking." (To enlarge the video, click the brackets in the lower right-hand corner. To reduce the video, press the Escape (Esc) button on your keyboard.) See how drinking alcohol can affect you as you age. Don't Smoke Smoking injures blood vessel walls and speeds up the process of hardening of the arteries. It increases your chances of stroke, heart disease, peripheral arterial disease, and several forms of cancer. If you smoke, quit. If you don't smoke, don't start. Once you quit, your risk of having a heart attack is reduced after the first year. So you have a lot to gain by quitting. See how to start a smoking quit plan geared to older adults.

### Question: What are the treatments for Primary Ciliary Dyskinesia ? ### Response:

Unfortunately, no treatment is available yet to fix faulty airway cilia. (Cilia are tiny, hair-like structures that line the airways.) Thus, treatment for primary ciliary dyskinesia (PCD) focuses on which symptoms and complications you have. The main goals of treating PCD are to: Control and treat lung, sinus, and ear infections Remove trapped mucus from the lungs and airways Specialists Involved Many doctors may help care for someone who has PCD. For example, a neonatologist may suspect PCD or another lung disorder if a newborn has breathing problems at birth. A neonatologist is a doctor who specializes in treating newborns. A pediatrician may suspect PCD if a child has chronic (ongoing) sinus, ear, and/or lung infections. A pediatrician is a doctor who specializes in treating children. This type of doctor provides children with ongoing care from an early age and treats conditions such as ear infections and breathing problems. An otolaryngologist also may help diagnose and treat PCD. This type of doctor treats ear, nose, and throat disorders and also is called an ear, nose, and throat (ENT) specialist. If a child has chronic sinus or ear infections, an ENT specialist may be involved in the child's care. A pulmonologist may help diagnose or treat lung problems related to PCD. This type of doctor specializes in diagnosing and treating lung diseases and conditions. Most people who have PCD have lung problems at some point in their lives. A pathologist is a doctor who specializes in identifying diseases by studying cells and tissues under a microscope. This type of doctor may help diagnose PCD by looking at cilia under a microscope. A pathologist also may look at mucus samples to see what types of bacteria are causing infections. This information can help your doctor decide which treatments to prescribe. Treatments for Breathing and Lung Problems Standard treatments for breathing and lung problems in people who have PCD are chest physical therapy (CPT), exercise, and medicines. One of the main goals of these treatments is to get you to cough. Coughing clears mucus from the airways, which is important for people who have PCD. For this reason, your doctor also may advise you to avoid medicines that suppress coughing. Chest Physical Therapy CPT also is called chest clapping or percussion. It involves pounding your chest and back over and over with your hands or a device to loosen the mucus from your lungs so that you can cough it up. You might sit down or lie on your stomach with your head down while you do CPT. Gravity and force help drain the mucus from your lungs. Some people find CPT hard or uncomfortable to do. Several devices have been made to help with CPT, such as: An electric chest clapper, known as a mechanical percussor. An inflatable therapy vest that uses high-frequency airwaves. The airwaves force the mucus that's deep in your lungs toward your upper airways so you can cough it up. A small hand-held device that you breathe out through. The device causes vibrations that dislodge the mucus. A mask that creates vibrations to help break the mucus loose from your airway walls. Breathing techniques also may help dislodge mucus so you can cough it up. These techniques include forcing out a couple of short breaths or deeper breaths and then doing relaxed breathing. This may help loosen the mucus in your lungs and open your airways. Exercise Aerobic exercise that makes you breathe harder helps loosen the mucus in your airways so you can cough it up. Exercise also helps improve your overall physical condition. Talk with your doctor about what types and amounts of exercise are safe for you or your child. Medicines If you have PCD, your doctor may prescribe antibiotics, bronchodilators, or anti-inflammatory medicines. These medicines help treat lung infections, open up the airways, and reduce swelling. Antibiotics are the main treatment to prevent or treat lung infections. Your doctor may prescribe oral or intravenous (IV) antibiotics. Oral antibiotics often are used to treat mild lung infections. For severe or hard-to-treat infections, you may be given IV antibiotics through a tube inserted into a vein. To help decide which antibiotics you need, your doctor may send mucus samples to a pathologist. The pathologist will try to find out which bacteria are causing the infection. Bronchodilators help open the airways by relaxing the muscles around them. You inhale these medicines. Often, they're taken just before CPT to help clear mucus from your lungs. You also may take bronchodilators before inhaling other medicines into your lungs. Anti-inflammatory medicines can help reduce swelling in your airways that's caused by ongoing infections. These medicines may be inhaled or oral. Treatments for Sinus and Ear Infections To treat infections, your doctor may recommend saline nasal washes and anti-inflammatory nasal spray. If these treatments aren't enough, you may need medicines, such as antibiotics. If antibiotics don't work, surgery may be an option. Tympanostomy (tim-pan-OS-toe-me) is a procedure in which small tubes are inserted into the eardrums to help drain mucus from the ears. This procedure may help children who have hearing problems caused by PCD. Nasal or sinus surgery may help drain the sinuses and provide short-term relief of symptoms. However, the long-term benefits of this treatment are unclear. Treatments for Advanced Lung Disease People who have PCD may develop a serious lung condition called bronchiectasis. This condition often is treated with medicines, hydration (drinking plenty of fluids), and CPT. If bronchiectasis severely affects part of your lung, surgery may be used to remove that area of lung. In very rare cases, if other treatments haven't worked, lung transplant may be an option for severe lung disease. A lung transplant is surgery to remove a person's diseased lung and replace it with a healthy lung from a deceased donor.

### Question: What is (are) Monitor Your Diabetes ? ### Response:

Sometimes, no matter how hard you try to keep your blood glucose levels in your target range, they will be too high or too low. Blood glucose thats too high or too low can make you feel sick. If you try to control your high or low blood glucose and cant, you may become even sicker and need help. Talk with your doctor to learn how to handle these emergencies. Learn about High Blood Glucose Levels If your blood glucose levels stay above 180 for more than 1 to 2 hours, they may be too high. See the "Daily Diabetes Record Page." High blood glucose, also called hyperglycemia, means you dont have enough insulin in your body. High blood glucose can happen if you - miss taking your diabetes medicines - eat too much - dont get enough physical activity - have an infection - get sick - are stressed - take medicines that can cause high blood glucose Be sure to tell your doctor about other medicines you take. When youre sick, be sure to check your blood glucose levels and keep taking your diabetes medicines. Read more about how to take care of yourself when youre sick in the section Take Care of Your Diabetes during Special Times or Events. Signs that your blood glucose levels may be too high are the following: - feeling thirsty - feeling weak or tired - headaches - urinating often - having trouble paying attention - blurry vision - yeast infections Very high blood glucose may also make you feel sick to your stomach. If your blood glucose levels are high much of the time, or if you have symptoms of high blood glucose, call your doctor. You may need a change in your healthy eating plan, physical activity plan, or medicines. Learn about Low Blood Glucose Levels If your blood glucose levels drop below 70, you have low blood glucose, also called hypoglycemia. Low blood glucose can come on fast and can be caused by - taking too much diabetes medicine - missing or delaying a meal - being more physically active than usual - drinking alcoholic beverages Sometimes, medicines you take for other health problems can cause your blood glucose levels to drop. Signs your blood glucose levels may be too low are the following: - hunger - dizziness or shakiness - confusion - being pale - sweating more - weakness - anxiety or moodiness - headaches - a fast heartbeat If your blood glucose levels drop lower, you could have severe hypoglycemia, where you pass out or have a seizure. A seizure occurs when cells in the brain release a rush of energy that can cause changes in behavior or muscle contractions. Some seizures are life threatening. If you have any of these symptoms, check your blood glucose levels. If your blood glucose levels are less than 70, have one of the following right away: - three or four glucose tablets - one serving of glucose gelthe amount equal to 15 grams of carbohydrates - 1/2 cup, or 4 ounces, of fruit juice - 1/2 cup, or 4 ounces, of a regularnondietsoft drink - 1 cup, or 8 ounces, of milk - five or six pieces of hard candy - 1 tablespoon of sugar, syrup, or honey After 15 minutes, check your blood glucose levels again. Repeat these steps until your blood glucose levels are 70 or above. If it will be at least 1 hour before your next meal, eat a snack. If you take diabetes medicines that can cause low blood glucose, always carry food for emergencies. You should also wear a medical identification bracelet or necklace that says you have diabetes. If you take insulin, keep a prescription glucagon kit at home and at other places where you often go. A glucagon kit has a vial of glucagon, a syringe, and a needle to inject the glucagon. Given as a shot, the glucagon quickly raises blood glucose. If you have severe hypoglycemia, youll need someone to help bring your blood glucose levels back to normal by giving you a glucagon shot. Show your family, friends, and coworkers how to give you a glucagon shot when you have severe hypoglycemia. Someone should call 911 for help if a glucagon kit is not available. Action Steps If You Take Insulin - Tell your doctor if you have low blood glucose, especially at the same time of the day or night, several times in a row. - Tell your doctor if youve passed out from low blood glucose. - Ask your doctor about glucagon. Glucagon is a medicine that raises blood glucose. - Show your family, friends, and coworkers how to give you a glucagon shot when you have severe hypoglycemia. - When you have severe hypoglycemia, someone should call 911 for help if a glucagon shot is not available. Action Steps If You Don't Take Insulin - Tell your doctor if you have low blood glucose, especially at the same time of the day or night, several times in a row. - Tell your doctor about other medicines you are taking. - Ask your doctor whether your diabetes medicines might cause low blood glucose.

### Question: What are the stages of Mycosis Fungoides and the Szary Syndrome ? ### Response:

Key Points - After mycosis fungoides and the Szary syndrome have been diagnosed, tests are done to find out if cancer cells have spread from the skin 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 mycosis fungoides and the Szary syndrome: - Stage I Mycosis Fungoides - Stage II Mycosis Fungoides - Stage III Mycosis Fungoides - Stage IV Mycosis Fungoides - Stage IV Szary Syndrome After mycosis fungoides and the Szary syndrome have been diagnosed, tests are done to find out if cancer cells have spread from the skin to other parts of the body. The process used to find out if cancer has spread from the skin 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 following procedures may be used in the staging process: - Chest x-ray : An x-ray of the organs and bones inside the chest. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the lymph nodes, chest, abdomen, and pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - Lymph node biopsy : The removal of all or part of a lymph node. A pathologist views the tissue under a microscope to look for cancer cells. - Bone marrow aspiration and biopsy : The removal of bone marrow and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow and bone under a microscope to look for signs of cancer. 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 mycosis fungoides spreads to the liver, the cancer cells in the liver are actually mycosis fungoides cells. The disease is metastatic mycosis fungoides, not liver cancer. The following stages are used for mycosis fungoides and the Szary syndrome: Stage I Mycosis Fungoides Stage I is divided into stage IA and stage IB as follows: - Stage IA: Less than 10% of the skin surface is covered with patches, papules, and/or plaques. - Stage IB: Ten percent or more of the skin surface is covered with patches, papules, and/or plaques. There may be abnormal lymphocytes in the blood but they are not cancerous. Stage II Mycosis Fungoides Stage II is divided into stage IIA and stage IIB as follows: - Stage IIA: Any amount of the skin surface is covered with patches, papules, and/or plaques. Lymph nodes are enlarged but cancer has not spread to them. - Stage IIB: One or more tumors that are 1 centimeter or larger are found on the skin. Lymph nodes may be enlarged but cancer has not spread to them. There may be abnormal lymphocytes in the blood but they are not cancerous. Stage III Mycosis Fungoides In stage III, nearly all of the skin is reddened and may have patches, papules, plaques, or tumors. Lymph nodes may be enlarged but cancer has not spread to them. There may be abnormal lymphocytes in the blood but they are not cancerous. Stage IV Mycosis Fungoides Stage IV is divided into stage IVA and stage IVB as follows: - Stage IVA: Most of the skin is reddened and any amount of the skin surface is covered with patches, papules, plaques, or tumors, and either: - cancer has spread to lymph nodes and there may be cancerous lymphocytes in the blood; or - there are cancerous lymphocytes in the blood and lymph nodes may be enlarged, but cancer has not spread to them. - Stage IVB: Most of the skin is reddened and any amount of the skin surface is covered with patches, papules, plaques, or tumors. Cancer has spread to other organs in the body. Lymph nodes may be enlarged and cancer may have spread to them. There may be cancerous lymphocytes in the blood. Stage IV Szary Syndrome In stage IV: - Most of the skin is reddened and covered with patches, papules, plaques, or tumors; and - There is a high level of cancerous lymphocytes in the blood; and - Lymph nodes may be enlarged and cancer may have spread to them.

### Question: What are the treatments for Holes in the Heart ? ### Response:

Many holes in the heart don't need treatment, but some do. Those that do often are repaired during infancy or early childhood. Sometimes adults are treated for holes in the heart if problems develop. The treatment your child receives depends on the type, location, and size of the hole. Other factors include your child's age, size, and general health. Treating an Atrial Septal Defect If a child has an atrial septal defect (ASD), routine checkups are done to see whether it closes on its own. About half of all ASDs close on their own over time, and about 20 percent close within the first year of life. Your child's doctor will let you know how often your child should have checkups. For an ASD, frequent checkups aren't needed. If an ASD requires treatment, catheter or surgical procedures are used to close the hole. Doctors often decide to close ASDs in children who still have medium- or large-sized holes by the time they're 2 to 5 years old. Catheter Procedure Until the early 1990s, surgery was the usual method for closing all ASDs. Now, thanks to medical advances, doctors can use catheter procedures to close secundum ASDs. These are the most common type of ASD. Before a catheter procedure, your child is given medicine so he or she will sleep and not feel any pain. Then, the doctor inserts a catheter (a thin, flexible tube) into a vein in the groin (upper thigh). He or she threads the tube to the heart's septum. A device made up of two small disks or an umbrella-like device is attached to the catheter. When the catheter reaches the septum, the device is pushed out of the catheter. The device is placed so that it plugs the hole between the atria. It's secured in place and the catheter is withdrawn from the body. Within 6 months, normal tissue grows in and over the device. The closure device does not need to be replaced as the child grows. Doctors often use echocardiography (echo), transesophageal (tranz-ih-sof-uh-JEE-ul) echo (TEE), and coronary angiography (an-jee-OG-rah-fee) to guide them in threading the catheter to the heart and closing the defect. TEE is a special type of echo that takes pictures of the heart through the esophagus. The esophagus is the passage leading from the mouth to the stomach. Catheter procedures are much easier on patients than surgery. They involve only a needle puncture in the skin where the catheter is inserted. This means that recovery is faster and easier. The outlook for children having this procedure is excellent. Closures are successful in more than 9 out of 10 patients, with no major leakage. Rarely, a defect is too large for catheter closure and surgery is needed. Surgery Open-heart surgery generally is done to repair primum or sinus venosus ASDs. Before the surgery, your child is given medicine so he or she will sleep and not feel any pain. Then, the cardiac surgeon makes an incision (cut) in the chest to reach the ASD. He or she repairs the defect with a special patch that covers the hole. A heart-lung bypass machine is used during the surgery so the surgeon can open the heart. The machine takes over the heart's pumping action and moves blood away from the heart. The outlook for children who have ASD surgery is excellent. On average, children spend 3 to 4 days in the hospital before going home. Complications, such as bleeding and infection, are very rare. In some children, the outer lining of the heart may become inflamed. This condition is called pericarditis (PER-i-kar-DI-tis). The inflammation causes fluid to collect around the heart in the weeks after surgery. Medicine usually can treat this condition. While in the hospital, your child will be given medicine as needed to reduce pain or anxiety. The doctors and nurses at the hospital will teach you how to care for your child at home. They will talk about preventing blows to the chest as the incision heals, limiting activity while your child recovers, bathing, scheduling ongoing care, and deciding when your child can go back to his or her regular activities. Treating a Ventricular Septal Defect Doctors may choose to monitor children who have ventricular septal defects (VSDs) but no symptoms of heart failure. This means regular checkups and tests to see whether the defect closes on its own or gets smaller. More than half of VSDs eventually close, usually by the time children are in preschool. Your child's doctor will let you know how often your child needs checkups. Checkups may range from once a month to once every 1 or 2 years. If treatment for a VSD is required, options include extra nutrition and surgery to close the VSD. Doctors also can use catheter procedures to close some VSDs. They may use this approach if surgery isn't possible or doesn't work. More research is needed to find out the risks and benefits of using catheter procedures to treat VSDs. Extra Nutrition Some infants who have VSDs don't grow and develop or gain weight as they should. These infants usually: Have large VSDs Are born too early Tire easily during feeding Doctors usually recommend extra nutrition or special feedings for these infants. These feedings are high-calorie formulas or breast milk supplements that give babies extra nourishment. Some infants need tube feeding. A small tube is inserted into the mouth and moved down into the stomach. Food is given through the tube. Tube feeding can add to or take the place of bottle feeding. This treatment often is short-term because a VSD that causes symptoms will likely require surgery. Surgery Most doctors recommend surgery to close large VSDs that are causing symptoms, affecting the aortic valve, or haven't closed by the time children are 1 year old. Surgery may be needed earlier if: A child doesn't gain weight Medicines are needed to control the symptoms of heart failure Rarely, medium-sized VSDs that are causing enlarged heart chambers are treated with surgery after infancy. However, most VSDs that require surgery are repaired in the first year of life. Doctors use open-heart surgery and patches to close VSDs.

### Question: What are the stages of Childhood Hodgkin Lymphoma ? ### Response:

Key Points - After childhood Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. - There are three ways that cancer spreads in the body. - Stages of childhood Hodgkin lymphoma may include A, B, E, and S. - The following stages are used for childhood Hodgkin lymphoma: - Stage I - Stage II - Stage III - Stage IV - Untreated Hodgkin lymphoma is divided into risk groups. After childhood Hodgkin lymphoma has been diagnosed, tests are done to find out if cancer cells have spread within the lymph system or to other parts of the body. The process used to find out if cancer has spread within the lymph system or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. Treatment is based on the stage and other factors that affect prognosis. The following tests and procedures may be used in the staging process: - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, such as the neck, chest, abdomen, or pelvis, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. Sometimes a PET scan and a CT scan are done at the same time. If there is any cancer, this increases the chance that it will be found. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). An MRI of the abdomen and pelvis may be done. - Bone marrow aspiration and biopsy : The removal of bone marrow and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow and bone under a microscope to look for abnormal cells. 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. Stages of childhood Hodgkin lymphoma may include A, B, E, and S. Childhood Hodgkin lymphoma may be described as follows: - A: The patient does not have B symptoms (fever, weight loss, or night sweats). - B: The patient has B symptoms. - E: Cancer is found in an organ or tissue that is not part of the lymph system but which may be next to an area of the lymph system affected by the cancer. - S: Cancer is found in the spleen. The following stages are used for childhood Hodgkin lymphoma: Stage I Stage I is divided into stage I and stage IE. - Stage I: Cancer is found in one of the following places in the lymph system: - One or more lymph nodes in one lymph node group. - Waldeyer's ring. - Thymus. - Spleen. - Stage IE: Cancer is found outside the lymph system in one organ or area. Stage II Stage II is divided into stage II and stage IIE. - Stage II: Cancer is found in two or more lymph node groups either above or below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIE: Cancer is found in one or more lymph node groups either above or below the diaphragm and outside the lymph nodes in a nearby organ or area. Stage III Stage III is divided into stage III, stage IIIE, stage IIIS, and stage IIIE,S. - Stage III: Cancer is found in lymph node groups above and below the diaphragm (the thin muscle below the lungs that helps breathing and separates the chest from the abdomen). - Stage IIIE: Cancer is found in lymph node groups above and below the diaphragm and outside the lymph nodes in a nearby organ or area. - Stage IIIS: Cancer is found in lymph node groups above and below the diaphragm, and in the spleen. - Stage IIIE,S: Cancer is found in lymph node groups above and below the diaphragm, outside the lymph nodes in a nearby organ or area, and in the spleen. Stage IV In stage IV, the cancer: - is found outside the lymph nodes throughout one or more organs, and may be in lymph nodes near those organs; or - is found outside the lymph nodes in one organ and has spread to areas far away from that organ; or - is found in the lung, liver, bone marrow, or cerebrospinal fluid (CSF). The cancer has not spread to the lung, liver, bone marrow, or CSF from nearby areas. Untreated Hodgkin lymphoma is divided into risk groups. Untreated childhood Hodgkin lymphoma is divided into risk groups based on the stage, size of the tumor, and whether the patient has B symptoms (fever, weight loss, or night sweats). The risk group is used to plan treatment. - Low-risk childhood Hodgkin lymphoma. - Intermediate-risk childhood Hodgkin lymphoma. - High-risk childhood Hodgkin lymphoma.

### Question: What causes Parkinson's Disease ? ### Response:

A Shortage of Dopamine Parkinson's disease occurs when nerve cells, or neurons, in an area of the brain that controls movement become impaired and/or die. Normally, these neurons produce an important brain chemical known as dopamine, but when the neurons die or become impaired, they produce less dopamine. This shortage of dopamine causes the movement problems of people with Parkinson's. Dopamine is a chemical messenger, or neurotransmitter. Dopamine is responsible for transmitting signals between the substantia nigra and multiple brain regions. The connection between the substantia nigra and the corpus striatum is critical to produce smooth, purposeful movement. Loss of dopamine in this circuit results in abnormal nerve-firing patterns within the brain that cause impaired movement. Loss of Norepinephrine People with Parkinson's also have loss of the nerve endings that produce the neurotransmitter norepinephrine. Norepinephrine, which is closely related to dopamine, is the main chemical messenger of the sympathetic nervous system. The sympathetic nervous system controls many automatic functions of the body, such as heart rate and blood pressure. The loss of norepinephrine might help explain several of the non-movement features of Parkinson's, such as fatigue, irregular blood pressure, decreased gastric motility or movement of food through the digestive tract, and postural hypotension. Postural hypotension is a sudden drop in blood pressure when a person stands up from a sitting or lying-down position. It may cause dizziness, lightheadedness, and in some cases, loss of balance or fainting. Lewy Bodies in Brain Cells Many brain cells of people with Parkinson's contain Lewy bodies. Lewy bodies are unusual deposits or clumps of the brain protein alpha-synuclein, along with other proteins, which are seen upon microscopic examination of the brain. Researchers do not yet know why Lewy bodies form or what role they play in the development of Parkinson's. The clumps may prevent the cell from functioning normally, or they may actually be helpful, perhaps by keeping harmful proteins "locked up" so the cells can function. Genetic Mutations Although some cases of Parkinson's appear to be hereditary, and a few can be traced to specific genetic mutations, most cases are sporadic. Sporadic means the disease occurs randomly and does not seem to run in families. Many researchers now believe that Parkinson's disease results from a combination of genetic and environmental factors. Scientists have identified several genetic mutations associated with Parkinson's including mutations in the alpha-synuclein gene. They think that many more genes may be linked to the disorder. Studying the genes responsible for inherited cases of Parkinson's can help researchers understand both inherited and sporadic cases. The same genes and proteins that are altered in inherited cases may also be altered in sporadic cases by environmental toxins or other factors. Researchers also hope that discovering genes will help identify new ways of treating Parkinson's. Environmental Toxins Although researchers increasingly recognize the importance of genetics in Parkinson's disease, most believe environmental exposures increase a person's risk of developing the disease. Even in inherited cases, exposure to toxins or other environmental factors may influence when symptoms of the disease appear or how the disease progresses. There are a number of toxins that can cause parkinsonian symptoms in humans. Researchers are pursuing the question of whether pesticides and other environmental factors not yet identified also may cause Parkinson's disease. Viruses are another possible environmental trigger for Parkinson's. Mitochondria and Free Radicals Research suggests that mitochondria may play a role in the development of Parkinson's disease. Mitochondria are the energy-producing components of the cell and are major sources of free radicals. Free radicals are molecules that damage membranes, proteins, DNA, and other parts of the cell. This damage is called oxidative stress. Changes to brain cells caused by oxidative stress, including free radical damage to DNA, proteins, and fats, have been found in people with Parkinson's. Clinical studies now underway test whether agents thought to improve energy metabolism and decrease oxidative stress slow the progression of Parkinson's disease. Recent evidence suggests that mutations in genes linked to Parkinsons disease result in mitochondrial dysfunction. Buildup of Harmful Proteins Other research suggests that the cell's protein disposal system may fail in people with Parkinson's, causing proteins like alpha-synuclein to build up to harmful levels and trigger premature cell death. Additional studies have found that clumps of protein that develop inside brain cells of people with Parkinson's may contribute to the death of nerve cells, or neurons. However, the exact role of the protein deposits remains unknown. These studies also found that inflammation, because of protein accumulation, toxins or other factors, may play a role in the disease. However, the exact role of the protein deposits remains unknown. Researchers are exploring the possibility of vaccine development to decrease or prevent the accumulation of alpha-synuclein. While mitochondrial dysfunction, oxidative stress, inflammation, and many other cellular processes may contribute to Parkinson's disease, scientists still do not know what causes cells that produce dopamine to die. Genes Linked to Parkinsons Researchers have discovered several genes that are linked to Parkinson's disease. The first to be identified was alpha-synuclein or SNCA . Studies have found that Lewy bodies from people with the sporadic form of Parkinson's contain clumps of alpha-synuclein protein. This discovery revealed a possible link between hereditary and sporadic forms of the disease. Other genes linked to Parkinson's include PARK2, PARK7, PINK1, and LRRK2. PARK2, PARK7, and PINK1 cause rare, early-onset forms of the disease. Mutations in the LRRK2 gene are common in specific populations, including in people with Parkinson's in North Africa. Researchers are continuing to study the normal functions and interactions of these genes in order to find clues about how Parkinson's develops. They also have identified a number of other genes and chromosome regions that may play a role in Parkinson's, but the nature of these links is not yet clear. Whole genome wide association studies, or GWAS, of thousands of people with Parkinson's disease are now underway to find gene variants that allow for an increased risk of developing Parkinson's but are not necessarily causes of this disorder by themselves. A recent international study found that two genes containing mutations known to cause rare hereditary forms of Parkinsons disease are also associated with the more common sporadic form of the disease. This finding came from a GWAS which looked at DNA samples of European people who had Parkinsons disease and from those who did not have the disorder.

### Question: How to diagnose Cyclic Vomiting Syndrome ? ### Response:

A specific test to diagnose cyclic vomiting syndrome does not exist; instead, a health care provider will rule out other conditions and diagnose the syndrome based upon - a medical and family history - a physical exam - a pattern or cycle of symptoms - blood tests - urine tests - imaging tests - upper GI endoscopy - a gastric emptying test Often, it is suspected that one of the following is causing their symptoms: - gastroparesisa disorder that slows or stops the movement of food from the stomach to the small intestine - gastroenteritisinflammation of the lining of the stomach, small intestine, and large intestine A diagnosis of cyclic vomiting syndrome may be difficult to make until the person sees a health care provider. A health care provider will suspect cyclic vomiting syndrome if the person suffers from repeat episodes of vomiting. Medical and Family History Taking a medical and family history is one of the first things a health care provider may do to help diagnose cyclic vomiting syndrome. He or she will ask the patient to provide a medical and family history. Physical Exam A physical exam may help diagnose other conditions besides cyclic vomiting syndrome. During a physical exam, a health care provider usually - examines a patients body - taps on specific areas of the patients body Pattern or Cycle of Symptoms in Children3 A health care provider will often suspect cyclic vomiting syndrome in a child when the child - has at least five separate episodes, or at least three separate episodes over 6 months - has episodes of intense nausea and vomiting lasting 1 hour to 10 days and occurring at least 1 week apart - has episodes that are similar to previous onesthey tend to start at the same time of day, last the same length of time, and occur with the same symptoms and level of intensity - vomits during episodes at least four times per hour for at least 1 hour - vomits and it is not attributed to another disorder - has absence of nausea and vomiting between episodes Pattern or Cycle of Symptoms in Adults4,5 A health care provider will often suspect cyclic vomiting syndrome in adults when the following is present for at least 3 months and the symptoms started more than 6 months ago: - Each episode of cyclic vomiting syndrome is usually similar to previous ones, meaning that episodes tend to start at the same time of day and last the same length of timeless than 1 week. - Three or more separate episodes in the past year. - Absence of nausea or vomiting between episodes. Blood Tests A nurse or technician will draw blood samples at a health care providers office or a commercial facility and send the samples to a lab for analysis. The blood test can tell the health care provider if the patient has any signs of dehydration or other problems. Urine Tests Urinalysis involves testing a urine sample. The patient collects a urine sample in a special container in a health care providers office or a commercial facility. A health care provider tests the sample in the same location or sends the sample to a lab for analysis. A urinalysis can rule out kidney problems or an infection. Imaging Tests The health care provider decides which test to order based on the symptoms, medical history, and physical exam. Upper GI series. A health care provider may order an upper GI series to look at the upper GI tract. A radiologista doctor who specializes in medical imagingperforms this test at a hospital or an outpatient center. This test does not require anesthesia. The patient should not eat or drink for 8 hours before the procedure, if possible. During the procedure, the patient will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Infants lie on a table and a health care provider gives them barium through a tiny tube placed in the nose that runs into the stomach. Barium coats the GI tract, making signs of obstruction or other problems that can cause vomiting show up more clearly on x rays. A patient may experience bloating and nausea for a short time after the test. The upper GI series can show other problems that may be causing symptoms, such as an ulcer or obstruction. Abdominal ultrasound. A health care provider may order an ultrasound to look at the organs in the abdomen. A technician uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The technician performs the procedure in a health care providers office, an outpatient center, or a hospital. A radiologist interprets the images. A patient does not need anesthesia. The abdominal ultrasound can show other problems that may be causing symptoms, such as gallstones. Upper Gastrointestinal Endoscopy This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. A health care provider may give a patient a liquid anesthetic to gargle or may spray anesthetic on the back of the patients throat. A nurse or technician will place an IV needle in a vein in the arm to administer sedation or anesthesia. Sedatives or anesthesia help a patient stay relaxed and comfortable. The gastroenterologist carefully inserts the endoscope into the mouth and feeds the endoscope down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. The upper GI endoscopy can show other problems that may be causing symptoms, such as an ulcer. A gastroenterologist may obtain a biopsya procedure that involves taking a small piece of tissue for examination with a microscopeof the small-intestinal lining during an upper GI endoscopy. The patient will not feel the biopsy. Gastric Emptying Test Also called gastric emptying scintigraphy, this test involves eating a bland mealsuch as eggs or an egg substitutethat contains a small amount of radioactive material. A specially trained technician performs the test in a radiology center or hospital, and a radiologist interprets the results; the patient does not need anesthesia. An external camera scans the abdomen to show where the radioactive material is located. The radiologist is then able to measure the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal.

### Question: What are the treatments for Varicose Veins ? ### Response:

Varicose veins are treated with lifestyle changes and medical procedures. The goals of treatment are to relieve symptoms, prevent complications, and improve appearance. If varicose veins cause few symptoms, your doctor may simply suggest making lifestyle changes. If your symptoms are more severe, your doctor may recommend one or more medical procedures. For example, you may need a medical procedure if you have a lot of pain, blood clots, or skin disorders caused by your varicose veins. Some people who have varicose veins choose to have procedures to improve how their veins look. Although treatment can help existing varicose veins, it can't keep new varicose veins from forming. Lifestyle Changes Lifestyle changes often are the first treatment for varicose veins. These changes can prevent varicose veins from getting worse, reduce pain, and delay other varicose veins from forming. Lifestyle changes include the following: Avoid standing or sitting for long periods without taking a break. When sitting, avoid crossing your legs. Keep your legs raised when sitting, resting, or sleeping. When you can, raise your legs above the level of your heart. Do physical activities to get your legs moving and improve muscle tone. This helps blood move through your veins. If you're overweight or obese, try to lose weight. This will improve blood flow and ease the pressure on your veins. Avoid wearing tight clothes, especially those that are tight around your waist, groin (upper thighs), and legs. Tight clothes can make varicose veins worse. Avoid wearing high heels for long periods. Lower heeled shoes can help tone your calf muscles. Toned muscles help blood move through the veins. Your doctor may recommend compression stockings. These stockings create gentle pressure up the leg. This pressure keeps blood from pooling and decreases swelling in the legs. There are three types of compression stockings. One type is support pantyhose. These offer the least amount of pressure. A second type is over-the-counter compression hose. These stockings give a little more pressure than support pantyhose. Over-the-counter compression hose are sold in medical supply stores and pharmacies. Prescription-strength compression hose are the third type of compression stockings. These stockings offer the greatest amount of pressure. They also are sold in medical supply stores and pharmacies. However, you need to be fitted for them in the store by a specially trained person. Medical Procedures Medical procedures are done either to remove varicose veins or to close them. Removing or closing varicose veins usually doesn't cause problems with blood flow because the blood starts moving through other veins. You may be treated with one or more of the procedures described below. Common side effects right after most of these procedures include bruising, swelling, skin discoloration, and slight pain. The side effects are most severe with vein stripping and ligation (li-GA-shun). Rarely, this procedure can cause severe pain, infections, blood clots, and scarring. Sclerotherapy Sclerotherapy (SKLER-o-ther-ah-pe) uses a liquid chemical to close off a varicose vein. The chemical is injected into the vein to cause irritation and scarring inside the vein. The irritation and scarring cause the vein to close off, and it fades away. This procedure often is used to treat smaller varicose veins and spider veins. It can be done in your doctor's office, while you stand. You may need several treatments to completely close off a vein. Treatments typically are done every 4 to 6 weeks. Following treatments, your legs will be wrapped in elastic bandaging to help with healing and decrease swelling. Microsclerotherapy Microsclerotherapy (MI-kro-SKLER-o-ther-ah-pe) is used to treat spider veins and other very small varicose veins. A small amount of liquid chemical is injected into a vein using a very fine needle. The chemical scars the inner lining of the vein, causing it to close off. Laser Surgery This procedure applies light energy from a laser onto a varicose vein. The laser light makes the vein fade away. Laser surgery mostly is used to treat smaller varicose veins. No cutting or injection of chemicals is involved. Endovenous Ablation Therapy Endovenous ablation (ab-LA-shun) therapy uses lasers or radiowaves to create heat to close off a varicose vein. Your doctor makes a tiny cut in your skin near the varicose vein. He or she then inserts a small tube called a catheter into the vein. A device at the tip of the tube heats up the inside of the vein and closes it off. You'll be awake during this procedure, but your doctor will numb the area around the vein. You usually can go home the same day as the procedure. Endoscopic Vein Surgery For endoscopic (en-do-SKOP-ik) vein surgery, your doctor will make a small cut in your skin near a varicose vein. He or she then uses a tiny camera at the end of a thin tube to move through the vein. A surgical device at the end of the camera is used to close the vein. Endoscopic vein surgery usually is used only in severe cases when varicose veins are causing skin ulcers (sores). After the procedure, you usually can return to your normal activities within a few weeks. Ambulatory Phlebectomy For ambulatory phlebectomy (fle-BEK-to-me), your doctor will make small cuts in your skin to remove small varicose veins. This procedure usually is done to remove the varicose veins closest to the surface of your skin. You'll be awake during the procedure, but your doctor will numb the area around the vein. Usually, you can go home the same day that the procedure is done. Vein Stripping and Ligation Vein stripping and ligation typically is done only for severe cases of varicose veins. The procedure involves tying shut and removing the veins through small cuts in your skin. You'll be given medicine to temporarily put you to sleep so you don't feel any pain during the procedure. Vein stripping and ligation usually is done as an outpatient procedure. The recovery time from the procedure is about 1 to 4 weeks.

### Question: How to diagnose Peripheral Arterial Disease (P.A.D.) ? ### Response:

Your Family and Medical History P.A.D. is diagnosed based on a person's medical and family histories, a physical exam, and results from medical tests. To learn about your medical and family histories, your doctor may ask about - your risk factors for P.A.D. For example, he or she may ask whether you smoke or have diabetes. - your symptoms, including any symptoms that occur when walking, exercising, sitting, standing, or climbing - your diet - any medicines you take, including prescription and over-the-counter medicines - family members with a history of heart or blood vessel diseases. your risk factors for P.A.D. For example, he or she may ask whether you smoke or have diabetes. your symptoms, including any symptoms that occur when walking, exercising, sitting, standing, or climbing your diet any medicines you take, including prescription and over-the-counter medicines family members with a history of heart or blood vessel diseases. The Physical Exam During the physical exam, your doctor will look for signs of P.A.D. He or she may check the blood flow in your legs or feet to see whether you have weak or absent pulses. Your doctor also may check the pulses in your leg arteries for an abnormal whooshing sound called a bruit (broo-E). He or she can hear this sound with a stethoscope. A bruit may be a warning sign of a narrowed or blocked artery. Your doctor may compare blood pressure between your limbs to see whether the pressure is lower in the affected limb. He or she may also check for poor wound healing or any changes in your hair, skin, or nails that might be signs of P.A.D. Diagnostic Tests Tests are used to diagnose P.A.D. These tests include - an ankle-brachial index (ABI). This test compares blood pressure in your ankle to blood pressure in your arm and shows how well blood is flowing in your limbs. ABI can show whether P.A.D. is affecting your limbs, but it wont show which blood vessels are narrowed or blocked. A normal ABI result is 1.0 or greater (with a range of 0.90 to 1.30). The test takes about 10 to 15 minutes to measure both arms and both ankles. This test may be done yearly to see whether P.A.D. is getting worse. an ankle-brachial index (ABI). This test compares blood pressure in your ankle to blood pressure in your arm and shows how well blood is flowing in your limbs. ABI can show whether P.A.D. is affecting your limbs, but it wont show which blood vessels are narrowed or blocked. A normal ABI result is 1.0 or greater (with a range of 0.90 to 1.30). The test takes about 10 to 15 minutes to measure both arms and both ankles. This test may be done yearly to see whether P.A.D. is getting worse. - a Doppler ultrasound. This test looks at blood flow in the major arteries and veins in the limbs. During this test, a handheld device is placed on your body and passed back and forth over the affected area. A computer converts sound waves into a picture of blood flow in the arteries and veins. The results of this test can show whether a blood vessel is blocked. The results also can help show the severity of P.A.D. a Doppler ultrasound. This test looks at blood flow in the major arteries and veins in the limbs. During this test, a handheld device is placed on your body and passed back and forth over the affected area. A computer converts sound waves into a picture of blood flow in the arteries and veins. The results of this test can show whether a blood vessel is blocked. The results also can help show the severity of P.A.D. - a treadmill test. This test shows if you have any problems during normal walking, how severe your symptoms are, and what level of exercise brings on your symptoms. You may have an ABI test before and after the treadmill test. This will help compare blood flow in your arms and legs before and after exercise. a treadmill test. This test shows if you have any problems during normal walking, how severe your symptoms are, and what level of exercise brings on your symptoms. You may have an ABI test before and after the treadmill test. This will help compare blood flow in your arms and legs before and after exercise. - a magnetic resonance angiogram (MRA).

### Question: How to diagnose Anxiety Disorders ? ### Response:

Anxiety disorders sometimes run in families, but no one knows for sure why some people have them while others don't. Anxiety disorders are more common among younger adults than older adults, and they typically start in early life. However, anyone can develop an anxiety disorder at any time. Below are risk factors for these anxiety disorders. - Generalized Anxiety Disorder (GAD) - Social Anxiety Disorder (Social Phobia) - Panic Disorder Generalized Anxiety Disorder (GAD) Social Anxiety Disorder (Social Phobia) Panic Disorder Generalized Anxiety Disorder - Risk Factors Generalized anxiety disorder (GAD) affects about 6.8 million American adults, including twice as many women as men. The disorder develops gradually and can begin at any point in the life cycle, although the years of highest risk are between childhood and middle age. The average age of onset is 31 years old. Social Phobia - Risk Factors Social phobia affects about 15 million American adults. Women and men are equally likely to develop the disorder, which usually begins in childhood or early adolescence. There is some evidence that genetic factors are involved. Panic Disorder - Risk Factors Panic disorder affects about 6 million American adults and is twice as common in women as men. Panic attacks often begin in late adolescence or early adulthood, but not everyone who experiences panic attacks will develop panic disorder. Many people have just one attack and never have another. The tendency to develop panic attacks appears to be inherited. Diagnosis Can Be Difficult There are a number of reasons why it can be difficult to accurately diagnose an anxiety disorder in older adults. - Anxiety disorders among older adults frequently occur at the same time as other illnesses such as depression, diabetes, heart disease, or a number of other medical illnesses. Problems with cognition (thinking) and changes in life circumstances can also complicate matters. Sometimes the physical signs of these illnesses can get mixed up with the symptoms of anxiety, making it difficult to determine if a person has a true anxiety disorder. For instance, a person with heart disease sometimes has chest pain, which can also be a symptom of a panic disorder.

For instance, a person with heart disease sometimes has chest pain, which can also be a symptom of a panic disorder. - Doctors can have difficulty distinguishing between anxiety caused by adapting to difficult life changes, and a true anxiety disorder. For example, if you fell and broke a hip, you may be justifiably fearful of going out for a while. But that would not mean you have developed an anxiety disorder.

For example, if you fell and broke a hip, you may be justifiably fearful of going out for a while. But that would not mean you have developed an anxiety disorder. - Sometimes the worrying symptoms of a medical illness can lead to an anxiety disorder. Or, sometimes the side effects of medication can cause anxiety. Also, a disability or a change in lifestyle caused by a medical illness may lead to an anxiety disorder. Muscle tightness, feeling very tense all the time, and difficulty sleeping can also be symptoms of a physical illness or an anxiety disorder, complicating diagnosis.

Also, a disability or a change in lifestyle caused by a medical illness may lead to an anxiety disorder. Muscle tightness, feeling very tense all the time, and difficulty sleeping can also be symptoms of a physical illness or an anxiety disorder, complicating diagnosis. Diagnosis Here is how these anxiety disorders are diagnosed. - Generalized Anxiety Disorder (GAD) - Panic Disorder - Social Anxiety Disorder (Social Phobia) Generalized Anxiety Disorder (GAD) Panic Disorder Social Anxiety Disorder (Social Phobia) Generalized Anxiety Disorder (GAD) - Diagnosis GAD can be diagnosed once a person worries excessively about a variety of everyday problems for at least 6 months. People with GAD may visit a doctor many times before they find out they have this disorder. They ask their doctors to help them with headaches or trouble falling asleep, which can be symptoms of GAD, but they don't always get the help they need right away. It may take doctors some time to be sure that a person has GAD instead of something else. Social Phobia - Diagnosis A doctor can tell that a person has social phobia if the person has had symptoms for at least 6 months. Social phobia usually starts during youth. Without treatment, it can last for many years or a lifetime. Panic Disorder - Diagnosis People with panic disorder may sometimes go from doctor to doctor for years and visit the emergency room repeatedly before someone correctly diagnoses their condition. This is unfortunate, because panic disorder is one of the most treatable of all the anxiety disorders, responding in most cases to certain kinds of medication or certain kinds of cognitive psychotherapy, which help change thinking patterns that lead to fear and anxiety. If You Have Symptoms Anxiety disorders are treatable. If you think you have an anxiety disorder, talk to your family doctor. Your doctor should do an exam to make sure that another physical problem isn't causing the symptoms. The doctor may refer you to a mental health specialist. You should feel comfortable talking with the mental health specialist you choose. If you do not, seek help elsewhere. Once you find a mental health specialist you are comfortable with, you should work as a team and make a plan to treat your anxiety disorder together. Talk About About Past Treatment People with anxiety disorders who have already received treatment for an anxiety disorder should tell their doctor about that treatment in detail. If they received medication, they should tell their doctor what medication was used, what the dosage was at the beginning of treatment, whether the dosage was increased or decreased while they were under treatment, what side effects may have occurred, and whether the treatment helped them become less anxious. If they received psychotherapy, they should describe the type of therapy, how often they attended sessions, and whether the therapy was useful.

### Question: What are the treatments for What I need to know about Bladder Control for Women ? ### Response:

Your doctor will likely offer several treatment choices. Some treatments are as simple as changing some daily habits. Other treatments require taking medicine or using a device. If nothing else seems to work, surgery may help a woman with stress incontinence regain her bladder control. Talk with your doctor about which treatments might work best for you. Pelvic Muscle Strengthening Many women prefer to try the simplest treatment choices first. Kegel exercises strengthen the pelvic muscles and don't require any equipment. Once you learn how to "Kegel," you can Kegel anywhere. The trick is finding the right muscles to squeeze. Your doctor or nurse can help make sure you are squeezing the right muscles. Your doctor may refer you to a specially trained physical therapist who will teach you to find and strengthen the sphincter muscles. Learning when to squeeze these muscles can also help stop the bladder spasms that cause urge incontinence. After about 6 to 8 weeks, you should notice that you have fewer leaks and more bladder control. Use the pelvic muscle exercise log included with the Kegel Exercise Tips sheet (Item C) to keep track of your progress. Changing Habits Timed voiding. By keeping track of the times you leak urine, you may notice certain times of day when you are most likely to have an accident. You can use that information to make planned trips to the bathroom ahead of time to avoid the accident. Once you have established a safe pattern, you can build your bladder control by stretching out the time between trips to the bathroom. By forcing your pelvic muscles to hold on longer, you make those muscles stronger. Diet changes. You may notice that certain foods and drinks cause you to urinate more often. You may find that avoiding caffeinated drinks like coffee, tea, or cola helps your bladder control. You can choose the decaf version of your favorite drink. Make sure you are not drinking too much fluid because that will cause you to make a large amount of urine. If you are bothered by nighttime urination, drink most of your fluids during the day and limit your drinking after dinner. You should not, however, avoid drinking fluids for fear of having an accident. Some foods may irritate your bladder and cause urgency. Talk with your doctor about diet changes that might affect your bladder. Weight loss. Extra body weight puts extra pressure on your bladder. By losing weight, you may be able to relieve some of that pressure and regain your bladder control. Medicines No medications are approved to treat stress urinary incontinence. But if you have an overactive bladder, your doctor may prescribe a medicine that can calm muscles and nerves. Medicines for overactive bladder come as pills, liquid, or a patch. Medicines to treat overactive bladder can cause your eyes to become dry. These medicines can also cause dry mouth and constipation. If you take medicine to treat an overactive bladder, you may need to take steps to deal with the side effects. - Use eye drops to keep your eyes moist. - Chew gum or suck on hard candy if dry mouth bothers you. Make it sugarless gum or candy to avoid tooth decay. - Take small sips of water throughout the day. Medicines for other conditions also can affect the nerves and muscles of the urinary tract in different ways. Pills to treat swelling-edema-or high blood pressure may increase urine output and contribute to bladder control problems. Talk with your doctor; you may find that taking a different medicine solves the problem without adding another prescription. The list of Medicines for Bladder Control (Item D) will give you more information about specific medicines. Pessaries A pessary is a plastic ring, similar to a contraceptive diaphragm, that is worn in the vagina. It will help support the walls of the vagina, lifting the bladder and nearby urethra, leading to less stress leakage. A doctor or nurse can fit you with the best shape and size pessary for you and teach you how to care for it. Many women use a pessary only during exercise while others wear their pessary all day to reduce stress leakage. If you use a pessary, you should see your doctor regularly to check for small scrapes in the vagina that can result from using the device. Nerve Stimulation Electrical stimulation of the nerves that control the bladder can improve symptoms of urgency, frequency, and urge incontinence, as well as bladder emptying problems, in some people. This treatment is usually offered to patients who cannot tolerate or do not benefit from medications. At first, your doctor will use a device outside your body to deliver stimulation through a wire implanted under your skin to see if the treatment relieves your symptoms. If the temporary treatment works well for you, you may be able to have a permanent device implanted that delivers stimulation to the nerves in your back, much like a pacemaker. The electrodes in the permanent device are placed in your lower back through a minor surgical procedure. You may need to return to the doctor for adjustments to find the right setting that controls your bladder symptoms. Surgery Doctors may suggest surgery to improve bladder control if other treatments have failed. Surgery helps only stress incontinence. It won't work for urge incontinence. Many surgical options have high rates of success. Most stress incontinence problems are caused by the bladder neck dropping toward the vagina. To correct this problem, the surgeon raises the bladder neck or urethra and supports it with a ribbon-like sling or web of strings attached to a muscle or bone. The sling holds up the bottom of the bladder and the top of the urethra to stop leakage. Catheterization If your bladder does not empty well as a result of nerve damage, you might leak urine. This condition is called overflow incontinence. You might use a catheter to empty your bladder. A catheter is a thin tube you can learn to insert through the urethra into the bladder to drain urine. You may use a catheter once in a while, a few times a day, or all of the time. If you use the catheter all the time, it will drain urine from your bladder into a bag you can hang from your leg. If you use a catheter all the time, you should watch for possible infections.

### Question: What are the treatments for Hearing Loss ? ### Response:

Your doctor can recommend strategies to help reduce the effects of a hearing loss. Scientists are studying ways to develop new, more effective methods to treat and prevent hearing loss. Hearing Aids A hearing aid is a small electronic device that you wear in or behind your ear. It makes some sounds louder so that a person with hearing loss can listen, communicate, and participate more fully in daily activities. A hearing aid can help people hear more in both quiet and noisy situations. However, only about one out of five people who would benefit from a hearing aid actually uses one. A hearing aid has three basic parts: a microphone, amplifier, and speaker. The hearing aid receives sound through a microphone, which converts the sound waves to electrical signals and sends them to an amplifier. The amplifier increases the power of the signals and then sends them to the ear through a speaker. Types of Hearing Aids There are a number of different types of hearing aids to treat different kinds of hearing loss. Choosing one will depend on the kind of hearing loss you have, you lifestyle, and your own preferences. - Behind-the-ear (BTE) hearing aids consist of a hard plastic case worn behind the ear and connected to a plastic earmold that fits inside the outer ear. The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss.

The electronic parts are held in the case behind the ear. Sound travels from the hearing aid through the earmold and into the ear. BTE aids are used by people of all ages for mild to profound hearing loss. - Open-fit hearing aids fit completely behind the ear with only a narrow tube inserted into the ear canal. This lets the ear canal remain open. Open-fit hearing aids may be a good choice for people with a buildup of earwax since this type of aid is less likely to be damaged by earwax. Some people may prefer the open-fit hearing aid because they do not perceive their voice as sounding plugged up.

Some people may prefer the open-fit hearing aid because they do not perceive their voice as sounding plugged up. - In-the-ear hearing aids fit completely inside the outer ear. The case holding the electronic components is made of hard plastic. Some in-the-ear hearing aids may also use a telecoil, which is a small magnetic coil that allows you to receive sound through the circuitry of the hearing aid, rather than through the microphone. You can use the telecoil when you use the telephone and when you are in public places that have installed induction loop systems, such as churches, schools, airports, and auditoriums.

The in-the-canal hearing aid is made to fit the size and shape of your ear canal. A completely-in-canal hearing aid is nearly hidden in the ear canal. Both types are used for mild to moderately severe hearing loss. Because they are small, canal aids may be difficult for a person to adjust and remove. In addition, canal aids have less space available for batteries and additional devices, such as a telecoil. They usually are not recommended for people with severe to profound hearing loss because their reduced size limits their power and volume.

They usually are not recommended for people with severe to profound hearing loss because their reduced size limits their power and volume. An audiologist or hearing aid specialist can help you determine if a hearing aid, or even two hearing aids, is the right treatment for you. Wearing two hearing aids may help balance sounds, improve your understanding of words in noisy situations, and make it easier to locate the source of sounds. Cochlear Implants If your hearing loss is severe and of a certain type, your doctor may suggest that you talk to an otolaryngologista surgeon who specializes in ear, nose, and throat diseasesabout a cochlear implant. A cochlear implant is a small electronic device that the surgeon places under the skin and behind the ear. The device picks up sounds, changes them to electrical signals, and sends them past the non-working part of the inner ear and on to the brain. A cochlear implant does not restore or create normal hearing. Instead, it can help people who are deaf or who have a severe hearing loss be more aware of their surroundings and understand speech, sometimes well enough to use the telephone. Learning to interpret sounds from the implant takes time and practice. A speech-language pathologist and audiologist can help you with this part of the process. Assistive Listening Devices Assistive listening devices devices can help you hear in certain listening environments. These can include telephone and cell phone amplifying devices, smart phone or tablet "apps," and closed circuit systems (induction coil loops) in places of worship, theaters, and auditoriums. TV listening systems help you listen to the television or the radio without being bothered by other noises around you. Some hearing aids can be plugged into televisions or stereos to help you hear better. New and Improved Treatments Under Study Researchers are studying the causes of hearing loss as well as new treatments. For example, they are studying ways to improve hearing aids so that wearers can hear certain sounds more clearly even when a person is surrounded by background noise. They are also studying how to improve cochlear implants to enhance a person's ability to understand sounds. And they are conducting a study on twins aged 50 and over to determine the extent to which age-related hearing loss runs in families.

### Question: What are the treatments for Prostate Enlargement: Benign Prostatic Hyperplasia ? ### Response:

The complications of benign prostatic hyperplasia treatment depend on the type of treatment. Medications Medications used to treat benign prostatic hyperplasia may have side effects that sometimes can be serious. Men who are prescribed medications to treat benign prostatic hyperplasia should discuss possible side effects with a health care provider before taking the medications. Men who experience the following side effects should contact a health care provider right away or get emergency medical care: - hives - rash - itching - shortness of breath - rapid, pounding, or irregular heartbeat - painful erection of the penis that lasts for hours - swelling of the eyes, face, tongue, lips, throat, arms, hands, feet, ankles, or lower legs - difficulty breathing or swallowing - chest pain - dizziness or fainting when standing up suddenly - sudden decrease or loss of vision - blurred vision - sudden decrease or loss of hearing - chest pain, dizziness, or nausea during sexual activity These side effects are mostly related to phosphodiesterase-5 inhibitors. Side effects related to alpha blockers include - dizziness or fainting when standing up suddenly - decreased sexual drive - problems with ejaculation Minimally Invasive Procedures Complications after minimally invasive procedures may include - UTIs - painful urination - difficulty urinating - an urgent or a frequent need to urinate - urinary incontinence - blood in the urine for several days after the procedure - sexual dysfunction - chronic prostatitislong-lasting inflammation of the prostate - recurring problems such as urinary retention and UTIs Most of the complications of minimally invasive procedures go away within a few days or weeks. Minimally invasive procedures are less likely to have complications than surgery. Surgery Complications after surgery may include - problems urinating - urinary incontinence - bleeding and blood clots - infection - scar tissue - sexual dysfunction - recurring problems such as urinary retention and UTIs Problems urinating. Men may initially have painful urination or difficulty urinating. They may experience urinary frequency, urgency, or retention. These problems will gradually lessen and, after a couple of months, urination will be easier and less frequent. Urinary incontinence. As the bladder returns to normal, men may have some temporary problems controlling urination. However, long-term urinary incontinence rarely occurs. The longer urinary problems existed before surgery, the longer it takes for the bladder to regain its full function after surgery. Bleeding and blood clots. After benign prostatic hyperplasia surgery, the prostate or tissues around it may bleed. Blood or blood clots may appear in urine. Some bleeding is normal and should clear up within several days. However, men should contact a health care provider right away if - they experience pain or discomfort - their urine contains large clots - their urine is so red it is difficult to see through Blood clots from benign prostatic hyperplasia surgery can pass into the bloodstream and lodge in other parts of the bodymost often the legs. Men should contact a health care provider right away if they experience swelling or discomfort in their legs. Infection. Use of a Foley catheter after benign prostatic hyperplasia surgery may increase the risk of a UTI. Anesthesia during surgery may cause urinary retention and also increase the risk of a UTI. In addition, the incision site of an open prostatectomy may become infected. A health care provider will prescribe antibiotics to treat infections. Scar tissue. In the year after the original surgery, scar tissue sometimes forms and requires surgical treatment. Scar tissue may form in the urethra and cause it to narrow. A urologist can solve this problem during an office visit by stretching the urethra. Rarely, the opening of the bladder becomes scarred and shrinks, causing blockage. This problem may require a surgical procedure similar to TUIP. Sexual dysfunction. Some men may experience temporary problems with sexual function after benign prostatic hyperplasia surgery. The length of time for restored sexual function depends on the type of benign prostatic hyperplasia surgery performed and how long symptoms were present before surgery. Many men have found that concerns about sexual function can interfere with sex as much as the benign prostatic hyperplasia surgery itself. Understanding the surgical procedure and talking about concerns with a health care provider before surgery often help men regain sexual function earlier. Many men find it helpful to talk with a counselor during the adjustment period after surgery. Even though it can take a while for sexual function to fully return, with time, most men can enjoy sex again. Most health care providers agree that if men with benign prostatic hyperplasia were able to maintain an erection before surgery, they will probably be able to have erections afterward. Surgery rarely causes a loss of erectile function. However, benign prostatic hyperplasia surgery most often cannot restore function that was lost before the procedure. Some men find a slight difference in the quality of orgasm after surgery. However, most report no difference. Prostate surgery may make men sterile, or unable to father children, by causing retrograde ejaculationthe backward flow of semen into the bladder. Men flush the semen out of the bladder when they urinate. In some cases, medications such as pseudoephedrine, found in many cold medications, or imipramine can treat retrograde ejaculation. These medications improve muscle tone at the bladder neck and keep semen from entering the bladder. Recurring problems. Men may require further treatment if prostate problems, including benign prostatic hyperplasia, return. Problems may arise when treatments for benign prostatic hyperplasia leave a good part of the prostate intact. About 10 percent of men treated with TURP or TUIP require additional surgery within 5 years. About 2 percent of men who have an open prostatectomy require additional surgery within 5 years.2 In the years after benign prostatic hyperplasia surgery or treatment, men should continue having a digital rectal exam once a year and have any symptoms checked by a health care provider. In some cases, the health care provider may recommend a digital rectal exam and checkup more than once a year.

### Question: How to diagnose Atrial Fibrillation ? ### Response:

Atrial fibrillation (AF) is diagnosed based on your medical and family histories, a physical exam, and the results from tests and procedures. Sometimes AF doesn't cause signs or symptoms. Thus, it may be found during a physical exam or EKG (electrocardiogram) test done for another purpose. If you have AF, your doctor will want to find out what is causing it. This will help him or her plan the best way to treat the condition. Specialists Involved Primary care doctors often are involved in the diagnosis and treatment of AF. These doctors include family practitioners and internists. Doctors who specialize in the diagnosis and treatment of heart disease also may be involved, such as: Cardiologists. These are doctors who diagnose and treat heart diseases and conditions. Electrophysiologists. These are cardiologists who specialize in arrhythmias. Medical and Family Histories Your doctor will likely ask questions about your: Signs and symptoms. What symptoms are you having? Have you had palpitations? Are you dizzy or short of breath? Are your feet or ankles swollen (a possible sign of heart failure)? Do you have any chest pain? Medical history. Do you have other health problems, such as a history of heart disease, high blood pressure, lung disease, diabetes, or thyroid problems? Family's medical history. Does anyone in your family have a history of AF? Has anyone in your family ever had heart disease or high blood pressure? Has anyone had thyroid problems? Does your family have a history of other illnesses or health problems? Health habits. Do you smoke or use alcohol or caffeine? Physical Exam Your doctor will do a complete cardiac exam. He or she will listen to the rate and rhythm of your heartbeat and take your pulse and blood pressure reading. Your doctor will likely check for any signs of heart muscle or heart valve problems. He or she will listen to your lungs to check for signs of heart failure. Your doctor also will check for swelling in your legs or feet and look for an enlarged thyroid gland or other signs of hyperthyroidism (too much thyroid hormone). Diagnostic Tests and Procedures EKG An EKG is a simple, painless test that records the heart's electrical activity. It's the most useful test for diagnosing AF. An EKG shows how fast your heart is beating and its rhythm (steady or irregular). It also records the strength and timing of electrical signals as they pass through your heart. A standard EKG only records the heartbeat for a few seconds. It won't detect AF that doesn't happen during the test. To diagnose paroxysmal AF, your doctor may ask you to wear a portable EKG monitor that can record your heartbeat for longer periods. The two most common types of portable EKGs are Holter and event monitors. Holter and Event Monitors A Holter monitor records the heart's electrical activity for a full 24- or 48-hour period. You wear small patches called electrodes on your chest. Wires connect these patches to a small, portable recorder. The recorder can be clipped to a belt, kept in a pocket, or hung around your neck. You wear the Holter monitor while you do your normal daily activities. This allows the monitor to record your heart for a longer time than a standard EKG. An event monitor is similar to a Holter monitor. You wear an event monitor while doing your normal activities. However, an event monitor only records your heart's electrical activity at certain times while you're wearing it. For many event monitors, you push a button to start the monitor when you feel symptoms. Other event monitors start automatically when they sense abnormal heart rhythms. You can wear an event monitor for weeks or until symptoms occur. Stress Test Some heart problems are easier to diagnose when your heart is working hard and beating fast. During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you can't exercise, you may be given medicine to make your heart work hard and beat fast. Echocardiography Echocardiography (echo) uses sound waves to create a moving picture of your heart. The test shows the size and shape of your heart and how well your heart chambers and valves are working. Echo also can identify areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow. This test sometimes is called transthoracic (trans-thor-AS-ik) echocardiography. It's painless and noninvasive (no instruments are inserted into the body). For the test, a device called a transducer is moved back and forth over your chest. The device sends special sound waves through your chest wall to your heart. The sound waves bounce off the structures of your heart, and a computer converts them into pictures on a screen. Transesophageal Echocardiography Transesophageal (trans-e-SOF-ah-ge-al) echo, or TEE, uses sound waves to take pictures of your heart through the esophagus. The esophagus is the passage leading from your mouth to your stomach. Your heart's upper chambers, the atria, are deep in your chest. They often can't be seen very well using transthoracic echo. Your doctor can see the atria much better using TEE. During this test, the transducer is attached to the end of a flexible tube. The tube is guided down your throat and into your esophagus. You'll likely be given medicine to help you relax during the procedure. TEE is used to detect blood clots that may be forming in the atria because of AF. Chest X Ray A chest x ray is a painless test that creates pictures of the structures in your chest, such as your heart and lungs. This test can show fluid buildup in the lungs and signs of other AF complications. Blood Tests Blood tests check the level of thyroid hormone in your body and the balance of your body's electrolytes. Electrolytes are minerals that help maintain fluid levels and acid-base balance in the body. They're essential for normal health and functioning of your body's cells and organs.

### Question: What are the treatments for Rheumatoid Arthritis ? ### Response:

Most Symptoms Are Treatable Doctors use a variety of approaches to treat rheumatoid arthritis. The goals of treatment are to help relieve pain, reduce swelling, slow down or help prevent joint damage, increase the ability to function, and improve the sense of well-being. Current treatment approaches include - lifestyle modification - medications - surgery - routine monitoring and ongoing care. lifestyle modification medications surgery routine monitoring and ongoing care. Balance Rest and Exercise People with rheumatoid arthritis need a good balance between rest and exercise; they should rest more when the disease is active and exercise more when it is not. Rest helps to reduce active joint inflammation and pain and to fight fatigue. The length of time for rest will vary from person to person, but in general, shorter rest breaks every now and then are more helpful than long times spent in bed. Exercise is important for maintaining healthy and strong muscles, preserving joint mobility, and maintaining flexibility. Exercise can also help people sleep well, reduce pain, maintain a positive attitude, and manage weight. Exercise programs should take into account the persons physical abilities, limitations, and changing needs. Learn more about the health benefits of exercise for older adults. More information about exercise and physical activity for older adults can be found at Go4Life, the exercise and physical activity campaign from the National Institute on Aging. Reduce Stress People with rheumatoid arthritis face emotional challenges as well as physical ones. The emotions they feel because of the diseasefear, anger, and frustrationcombined with any pain and physical limitations can increase their stress level. Finding ways to reduce stress is important. Regular rest periods can help and so can relaxation, distraction, or visualization exercises. Exercise programs, participation in support groups, and good communication with the health care team are other ways to reduce stress. For more information on exercise classes, you may want to contact the Arthritis Foundation at 1-800-283-7800. Learn about relaxation techniques that may relieve tension. Eat a Healthful Diet Special diets, vitamin supplements, and other alternative approaches have been suggested for treating rheumatoid arthritis. Although such approaches may not be harmful, scientific studies have not yet shown any benefits.

Although such approaches may not be harmful, scientific studies have not yet shown any benefits. See Eating Well as You Get Older for more about healthy eating. Reduce Stress on Joints Some people find using a splint for a short time around a painful joint reduces pain and swelling by supporting the joint and letting it rest. Splints are used mostly on wrists and hands, but also on ankles and feet. A doctor or a physical or occupational therapist can help a person choose a splint and make sure it fits properly. Other ways to reduce stress on joints include - self-help devices (for example, zipper pullers, long-handled shoe horns) - devices to help with getting on and off chairs, toilet seats, and beds - changes in the ways that a person carries out daily activities. self-help devices (for example, zipper pullers, long-handled shoe horns) devices to help with getting on and off chairs, toilet seats, and beds changes in the ways that a person carries out daily activities. Medications Most people who have rheumatoid arthritis take medications. Some drugs only provide relief for pain; others reduce inflammation. Still others, called disease-modifying anti-rheumatic drugs or DMARDs, can often slow the course of the disease. - DMARDs include methotrexate, leflunomide, sulfasalazine, and cyclosporine. DMARDs include methotrexate, leflunomide, sulfasalazine, and cyclosporine. - Steroids, which are also called corticosteroids, are another type of drug used to reduce inflammation for people with rheumatoid arthritis. Cortisone, hydrocortisone, and prednisone are some commonly used steroids.

Cortisone, hydrocortisone, and prednisone are some commonly used steroids. - DMARDS called biologic response modifiers also can help reduce joint damage. These drugs include etanercept, infliximab, anakinra, golimumab, adalimumab, rituximab, and abatacept. DMARDS called biologic response modifiers also can help reduce joint damage. These drugs include etanercept, infliximab, anakinra, golimumab, adalimumab, rituximab, and abatacept. - Another DMARD, tofacitinib, from a new class of drugs called jak kinase (JAK) inhibitors is also available. Another DMARD, tofacitinib, from a new class of drugs called jak kinase (JAK) inhibitors is also available. Early treatment with powerful drugs and drug combinations -- including biologic response modifiers and DMARDs -- instead of single drugs may help prevent the disease from progressing and greatly reduce joint damage. Surgery In some cases, a doctor will recommend surgery to restore function or relieve pain in a damaged joint. Surgery may also improve a person's ability to perform daily activities. Joint replacement and tendon reconstruction are two types of surgery available to patients with severe joint damage. Routine Monitoring and Ongoing Care Regular medical care is important to monitor the course of the disease, determine the effectiveness and any negative effects of medications, and change therapies as needed. Monitoring typically includes regular visits to the doctor. It also may include blood, urine, and other laboratory tests and x rays. Monitor Osteoporosis Risk People with rheumatoid arthritis may want to discuss preventing osteoporosis with their doctors as part of their long-term, ongoing care. Osteoporosis is a condition in which bones become weakened and fragile. Having rheumatoid arthritis increases the risk of developing osteoporosis for both men and women, particularly if a person takes corticosteroids. Such patients may want to discuss with their doctors the potential benefits of calcium and vitamin D supplements or other treatments for osteoporosis. See What is Osteoporosis? to learn more about this disease.

### Question: How to diagnose Pleurisy and Other Pleural Disorders ? ### Response:

Your doctor will diagnose pleurisy or another pleural disorder based on your medical history, a physical exam, and test results. Your doctor will want to rule out other causes of your symptoms. He or she also will want to find the underlying cause of the pleurisy or other pleural disorder so it can be treated. Medical History Your doctor may ask detailed questions about your medical history. He or she likely will ask you to describe any pain, especially: What it feels like Where it's located and whether you can feel it in your arms, jaw, or shoulders When it started and whether it goes away and then comes back What makes it better or worse Your doctor also may ask whether you have other symptoms, such as shortness of breath, coughing, or palpitations. Palpitations are feelings that your heart is skipping a beat, fluttering, or beating too hard or fast. Your doctor also may ask whether you've ever: Had heart disease. Smoked. Traveled to places where you may have been exposed to tuberculosis. Had a job that exposed you to asbestos. Asbestos is a mineral that, at one time, was widely used in many industries. Your doctor also may ask about medicines you take or have taken. Reactions to some medicines can cause pleurisy or other pleural disorders. Physical Exam Your doctor will listen to your breathing with a stethoscope to find out whether your lungs are making any abnormal sounds. If you have pleurisy, the inflamed layers of the pleura make a rough, scratchy sound as they rub against each other when you breathe. Doctors call this a pleural friction rub. If your doctor hears the friction rub, he or she will know that you have pleurisy. If you have a pleural effusion, fluid buildup in the pleural space will prevent a friction rub. But if you have a lot of fluid, your doctor may hear a dull sound when he or she taps on your chest. Or, he or she may have trouble hearing any breathing sounds. Muffled or dull breathing sounds also can be a sign of a pneumothorax (a buildup of air or gas in the pleural space). Diagnostic Tests Depending on the results of your physical exam, your doctor may recommend tests. Chest X Ray Achest x rayis a painless test that creates a picture of the structures in your chest, such as your heart, lungs, and blood vessels. This test may show air or fluid in the pleural space. A chest x ray also may show what's causing a pleural disorderfor example, pneumonia, a fractured rib, or a lung tumor. Sometimes a chest x ray is taken while you lie on your side. This position can show fluid that didn't appear on an x ray taken while you were standing. Chest CT Scan A chest computed tomography (to-MOG-rah-fee) scan, orchest CT scan,is a painless test that creates precise pictures of the structures in your chest. This test provides a computer-generated picture of your lungs that can show pockets of fluid. A chest CT scan also may show signs of pneumonia, a lung abscess, a tumor, or other possible causes of pleural disorders. Ultrasound This test uses sound waves to create pictures of your lungs. An ultrasound may show where fluid is located in your chest. The test also can show some tumors. Chest MRI A chest magnetic resonance imaging scan, orchest MRI,uses radio waves, magnets, and a computer to created detailed pictures of the structures in your chest. This test can show pleural effusions and tumors. This test also is called a magnetic resonance (MR) scan or a nuclear magnetic resonance (NMR) scan. Blood Tests Blood testscan show whether you have an illness that increases your risk of pleurisy or another pleural disorder. Such illnesses include bacterial or viral infections, pneumonia, pancreatitis (an inflamed pancreas), kidney disease, or lupus. Arterial Blood Gas Test For this test, a blood sample is taken from an artery, usually in your wrist. The blood's oxygen and carbon dioxide levels are checked. This test shows how well your lungs are taking in oxygen. Thoracentesis Once your doctor knows whether fluid has built up in the pleural space and where it is, he or she can remove a sample for testing. This is done using a procedure calledthoracentesis(THOR-ah-sen-TE-sis). During the procedure, your doctor inserts a thin needle or plastic tube into the pleural space and draws out the excess fluid. After the fluid is removed from your chest, it's sent for testing. The risks of thoracentesissuch as pain, bleeding, and infectionusually are minor. They get better on their own, or they're easily treated. Your doctor may do a chest x ray after the procedure to check for complications. Fluid Analysis The fluid removed during thoracentesis is examined under a microscope. It's checked for signs of infection, cancer, or other conditions that can cause fluid or blood to build up in the pleural space. Biopsy Your doctor may suspect that tuberculosis or cancer has caused fluid to build up in your pleural space. If so, he or she may want to look at a small piece of the pleura under a microscope. To take a tissue sample, your doctor may do one of the following procedures: Insert a needle into your chest to remove a small sample of the pleura's outer layer. Insert a tube with a light on the end (endoscope) into tiny cuts in your chest wall so that he or she can see the pleura. Your doctor can then snip out small pieces of tissue. This procedure must be done in a hospital. You'll be given medicine to make you sleep during the procedure. Snip out a sample of the pleura through a small cut in your chest wall. This is called an open pleural biopsy. It's usually done if the sample from the needle biopsy is too small for an accurate diagnosis. This procedure must be done in a hospital. You'll be given medicine to make you sleep during the procedure.

### Question: What are the symptoms of Parkinson's Disease ? ### Response:

Parkinson's disease does not affect everyone the same way. Symptoms of the disorder and the rate of progression differ among people with the disease. Sometimes people dismiss early symptoms of Parkinson's as the effects of normal aging. There are no medical tests to definitively diagnose the disease, so it can be difficult to diagnose accurately. Early Symptoms Early symptoms of Parkinson's disease are subtle and occur gradually. For example, affected people may feel mild tremors or have difficulty getting out of a chair. They may notice that they speak too softly or that their handwriting is slow and looks cramped or small. This very early period may last a long time before the more classic and obvious symptoms appear. Friends or family members may be the first to notice changes in someone with early Parkinson's. They may see that the person's face lacks expression and animation, a condition known as "masked face," or that the person does not move an arm or leg normally. They also may notice that the person seems stiff, unsteady, or unusually slow. As the Disease Progresses As the disease progresses, symptoms may begin to interfere with daily activities. The shaking or tremor may make it difficult to hold utensils steady or read a newspaper. Tremor is usually the symptom that causes people to seek medical help. People with Parkinson's often develop a so-called parkinsonian gait that includes a tendency to lean forward, small quick steps as if hurrying forward (called festination), and reduced swinging of the arms. They also may have trouble initiating or continuing movement, which is known as freezing. Symptoms often begin on one side of the body or even in one limb on one side of the body. As the disease progresses, it eventually affects both sides. However, the symptoms may still be more severe on one side than on the other. Four Primary Symptoms The four primary symptoms of Parkinson's are tremor, rigidity, slowness of movement (bradykinesia), and impaired balance (postural instability). - Tremor often begins in a hand, although sometimes a foot or the jaw is affected first. It is most obvious when the hand is at rest or when a person is under stress. It usually disappears during sleep or improves with a deliberate movement. - Rigidity, or a resistance to movement, affects most people with Parkinson's. It becomes obvious when another person tries to move the individual's arm, such as during a neurological examination. The arm will move only in ratchet-like or short, jerky movements known as "cogwheel" rigidity. - Bradykinesia, or the slowing down and loss of spontaneous and automatic movement, is particularly frustrating because it may make simple tasks somewhat difficult. Activities once performed quickly and easily, such as washing or dressing, may take several hours. - Postural instability, or impaired balance, causes people with Parkinson's to fall easily. They also may develop a stooped posture with a bowed head and droopy shoulders. Tremor often begins in a hand, although sometimes a foot or the jaw is affected first.

They also may develop a stooped posture with a bowed head and droopy shoulders. Other Symptoms A number of other symptoms may accompany Parkinson's disease. Some are minor; others are not. Many can be treated with medication or physical therapy. No one can predict which symptoms will affect an individual person, and the intensity of the symptoms varies from person to person. Many people note that prior to experiencing motor problems of stiffness and tremor, they had symptoms of a sleep disorder, constipation, decreased ability to smell, and restless legs. Other symptoms include - depression - emotional changes - difficulty swallowing and chewing - speech changes - urinary problems or constipation - skin problems, sleep problems - dementia or other cognitive problems - orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) - muscle cramps and dystonia (twisting and repetitive movements) - pain - fatigue and loss of energy - sexual dysfunction. depression emotional changes difficulty swallowing and chewing speech changes urinary problems or constipation skin problems, sleep problems dementia or other cognitive problems orthostatic hypotension (a sudden drop in blood pressure when standing up from a sitting or lying down position) muscle cramps and dystonia (twisting and repetitive movements) pain fatigue and loss of energy sexual dysfunction. A number of disorders can cause symptoms similar to those of Parkinson's disease. People with Parkinson's-like symptoms that result from other causes are sometimes said to have parkinsonism. While these disorders initially may be misdiagnosed as Parkinson's, certain medical tests, as well as response to drug treatment, may help to distinguish them from Parkinson's. Diagnosis Can Be Difficult There are currently no blood, or laboratory tests to diagnose sporadic Parkinson's disease. Diagnosis is based on a person's medical history and a neurological examination, but the disease can be difficult to diagnose accurately. Early signs and symptoms of Parkinson's may sometimes be dismissed as the effects of normal aging. A doctor may need to observe the person for some time until it is clear that the symptoms are consistently present. Improvement after initiating medication is another important hallmark of Parkinson's disease. Doctors may sometimes request brain scans or laboratory tests to rule out other diseases. However, computed tomography (CT) and magnetic resonance imaging (MRI) brain scans of people with Parkinson's usually appear normal. Recently, the FDA (Food and Drug Administration) has approved an imaging technique called DaTscan, which may help to increase accuracy of the diagnosis of Parkinsons disease. Since many other diseases have similar features but require different treatments, it is very important to make an exact diagnosis as soon as possible to ensure proper treatment.

### Question: What are the stages of Ovarian Epithelial, Fallopian Tube, and Primary Peritoneal Cancer ? ### Response:

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.

### Question: What causes Chronic Diarrhea in Children ? ### Response:

To determine the cause of chronic diarrhea in children, the health care provider will take a complete medical and family history and conduct a physical exam, and may perform tests. Medical and family history. Taking a medical and family history is one of the first things a health care provider may do to help determine the cause of chronic diarrhea. He or she will ask for information about symptoms, such as - how long the child has had diarrhea - the amount of stool passed - the frequency of diarrhea - the appearance of the stool - the presence of other symptoms that accompany diarrhea The health care provider will ask about the childs diet and may recommend keeping a diary of the childs diet and bowel habits. If the health care provider suspects a food allergy or intolerance, he or she may recommend changing the childs diet to see if symptoms improve. The health care provider may also ask about family medical history. Some of the conditions that cause chronic diarrhea, such as celiac disease and lactose intolerance, run in families. Physical exam. After taking a medical history, a health care provider will perform a physical exam, which may help determine the cause of chronic diarrhea. During a physical exam, a health care provider usually - examines a childs body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the childs body Tests. The health care provider may perform one or more of the following tests: - Stool test. A stool test is the analysis of a sample of stool. The health care provider will give the parent or caretaker a container for catching and storing the stool. The parent or caretaker returns the sample to the health care provider or a commercial facility that will send the sample to a lab for analysis. Stool tests can show the presence of blood, bacteria, or parasites or signs of diseases and disorders. The health care provider may also do a rectal exam, sometimes during the physical exam. For a rectal exam, the health care provider inserts a gloved, lubricated finger into the rectum to check for blood in the stool. - Blood test. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can show signs of certain diseases and disorders that can cause chronic diarrhea in children, including - high levels of white blood cells, which may be a sign of inflammation or infection somewhere in the body - anemia, which may be a sign of bleeding in the GI tract or of malabsorption - the presence of certain antibodiesproteins that react against the bodys own cells or tissueswhich may be a sign of celiac disease - Hydrogen breath test. This test measures the amount of hydrogen in a childs breath. Normally, only a small amount of hydrogen is detectable in the breath. However, bacteria break down sugarssuch as lactose and fructosethat are not digested by the small intestine and produce high levels of hydrogen. In small intestinal bacterial overgrowth, bacteria break down sugars in the small intestine and produce hydrogen. For this test, the child breathes into a balloonlike container that measures hydrogen. Then, the child drinks a lactose-loaded beverage, and the childs breath is analyzed at regular intervals to measure the amount of hydrogen. In most cases, a health care provider performs this test at a hospital, on an outpatient basis. A health care provider may use a hydrogen breath test to check for signs of lactose intolerance, fructose intolerance, or small intestinal bacterial overgrowth. - Upper GI endoscopy. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenum, the first part of the small intestine. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. The endoscope is carefully fed down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A child may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. A health care provider will place an intravenous (IV) needle in a vein in the arm if general anesthesia is given. The health care provider may use instruments passed through the endoscope to perform a biopsy or collect fluid. A biopsy is a procedure that involves taking a piece of tissue for examination with a microscope. A pathologista doctor who specializes in diagnosing diseasesexamines the tissues in a lab. This test can show problems in the upper GI tract that may cause chronic diarrhea. For example, a biopsy of the small intestine can show signs of celiac disease. A health care provider may use a fluid sample from the small intestine to check for bacteria to diagnose small intestinal bacterial overgrowth. - Flexible sigmoidoscopy or colonoscopy. While these tests are similar, a health care provider uses a colonoscopy to view the rectum and entire colon and a flexible sigmoidoscopy to view just the rectum and lower colon. A gastroenterologist performs these tests at a hospital or an outpatient center. For both tests, the health care provider will give written bowel prep instructions for the child to follow at home. The health care provider may ask that the child follow a clear liquid diet the day before either test. The child may require a laxative for 4 days before either test or only the day before either test. The child may require an enema the day before either test. These medications cause diarrhea, so the child should stay close to a bathroom during the bowel prep. In most cases, light anesthesia, and possibly pain medication, helps the child relax. For either test, the child will lie on a table while the gastroenterologist inserts a flexible tube into the anus. A small camera on the tube sends a video image of the intestinal lining to a computer screen. The gastroenterologist may also perform a biopsy by taking a small piece of tissue from the intestinal lining. The child will not feel the biopsy. These tests can show problems in the rectum or colon, such as signs of IBD. Cramping or bloating may occur during the first hour after these tests. The child should recover fully by the next day and be able to return to a normal diet.

### Question: Who is at risk for Stroke? ? ### Response:

A risk factor is a condition or behavior that increases your chances of getting a disease. Having a risk factor for stroke doesn't mean you'll have a stroke. On the other hand, not having a risk factor doesn't mean you'll avoid a stroke. But your risk of stroke grows as the number and severity of risk factors increase. These risk factors for stroke cannot be changed by medical treatment or lifestyle changes. - Age. Although stroke risk increases with age, stroke can occur at any age. Recent studies have found that stroke rates among people under 55 grew from 13 percent in 1993-1994, to 19 percent in 2005. Experts speculate the increase may be due to a rise in risk factors such as diabetes, obesity, and high cholesterol. Age. Although stroke risk increases with age, stroke can occur at any age.

Gender. Men have a higher risk for stroke, but more women die from stroke. - Race. People from certain ethnic groups have a higher risk of stroke. For African Americans, stroke is more common and more deadly even in young and middle-aged adults than for any ethnic or other racial group in the U.S. Studies show that the age-adjusted incidence of stroke is about twice as high in African Americans and Hispanic Americans as in Caucasians. An important risk factor for African Americans is sickle cell disease, which can cause a narrowing of arteries and disrupt blood flow. Race.

Stroke seems to run in some families. Several factors may contribute to familial stroke. Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes. The influence of a common lifestyle among family members could also contribute to familial stroke. Family history of stroke. Stroke seems to run in some families. Several factors may contribute to familial stroke. Members of a family might have a genetic tendency for stroke risk factors, such as an inherited predisposition for high blood pressure (hypertension) or diabetes. The influence of a common lifestyle among family members could also contribute to familial stroke. Some of the most important risk factors for stroke that CAN be treated are - high blood pressure - smoking - heart disease - high blood cholesterol - warning signs or history of a stroke - diabetes. high blood pressure smoking heart disease high blood cholesterol warning signs or history of a stroke diabetes. High Blood Pressure High blood pressure, also called hypertension, is by far the most potent risk factor for stroke. If your blood pressure is high, you and your doctor need to work out an individual strategy to bring it down to the normal range. Here are some ways to reduce blood pressure: - Maintain proper weight. - Avoid drugs known to raise blood pressure. - Cut down on salt. - Eat fruits and vegetables to increase potassium in your diet. - Exercise more. Maintain proper weight. Avoid drugs known to raise blood pressure. Cut down on salt. Eat fruits and vegetables to increase potassium in your diet. Exercise more. Your doctor may prescribe medicines that help lower blood pressure. Controlling blood pressure will also help you avoid heart disease, diabetes, and kidney failure. Smoking Cigarette smoking has been linked to the buildup of fatty substances in the carotid artery, the main neck artery supplying blood to the brain. Blockage of this artery is the leading cause of stroke in Americans. Also, nicotine raises blood pressure, carbon monoxide reduces the amount of oxygen your blood can carry to the brain, and cigarette smoke makes your blood thicker and more likely to clot. Your doctor can recommend programs and medications that may help you quit smoking. By quitting -- at any age -- you also reduce your risk of lung disease, heart disease, and a number of cancers including lung cancer. Heart Disease Heart disease, including common heart disorders such as coronary artery disease, valve defects, irregular heart beat, and enlargement of one of the heart's chambers, can result in blood clots that may break loose and block vessels in or leading to the brain. The most common blood vessel disease, caused by the buildup of fatty deposits in the arteries, is called atherosclerosis, also known as hardening of the arteries. Your doctor will treat your heart disease and may also prescribe medication, such as aspirin, to help prevent the formation of clots. Your doctor may recommend surgery to clean out a clogged neck artery if you match a particular risk profile. High Blood Cholesterol A high level of total cholesterol in the blood is a major risk factor for heart disease, which raises your risk of stroke. Your doctor may recommend changes in your diet or medicines to lower your cholesterol. Warning Signs or History of Stroke Experiencing warning signs and having a history of stroke are also risk factors for stroke. Transient ischemic attacks, or TIAs, are brief episodes of stroke warning signs that may last only a few moments and then go away. If you experience a TIA, get help at once. Call 911. If you have had a stroke in the past, it's important to reduce your risk of a second stroke. Your brain helps you recover from a stroke by drawing on body systems that now do double duty. That means a second stroke can be twice as bad. Diabetes Having diabetes is another risk factor for stroke. You may think this disorder affects only the body's ability to use sugar, or glucose. But it also causes destructive changes in the blood vessels throughout the body, including the brain. Also, if blood glucose levels are high at the time of a stroke, then brain damage is usually more severe and extensive than when blood glucose is well-controlled. Treating diabetes can delay the onset of complications that increase the risk of stroke.

### Question: How to diagnose Angina ? ### Response:

The most important issues to address when you go to the doctor with chest pain are: What's causing the chest pain Whether you're having or are about to have a heart attack Angina is a symptom of an underlying heart problem, usually coronary heart disease (CHD). The type of angina pain you have can be a sign of how severe the CHD is and whether it's likely to cause a heart attack. If you have chest pain, your doctor will want to find out whether it's angina. He or she also will want to know whether the angina is stable or unstable. If it's unstable, you may need emergency medical treatment to try to prevent a heart attack. To diagnose chest pain as stable or unstable angina, your doctor will do a physical exam, ask about your symptoms, and ask about your risk factors for and your family history of CHD or other heart diseases. Your doctor also may ask questions about your symptoms, such as: What brings on the pain or discomfort and what relieves it? What does the pain or discomfort feel like (for example, heaviness or tightness)? How often does the pain occur? Where do you feel the pain or discomfort? How severe is the pain or discomfort? How long does the pain or discomfort last? Diagnostic Tests and Procedures If your doctor thinks that you have unstable angina or that your angina is related to a serious heart condition, he or she may recommend one or more tests. EKG (Electrocardiogram) An EKG is a simple, painless test that detects and records the hearts electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through the heart. An EKG can show signs of heart damage due to CHD and signs of a previous or current heart attack. However, some people who have angina have normal EKGs. Stress Testing During stress testing, you exercise to make your heart work hard and beat fast while heart tests are done. If you cant exercise, you may be given medicine to make your heart work hard and beat fast. When your heart is working hard and beating fast, it needs more blood and oxygen. Plaque-narrowed arteries can't supply enough oxygen-rich blood to meet your heart's needs. A stress test can show possible signs and symptoms of CHD, such as: Abnormal changes in your heart rate or blood pressure Shortness of breath or chest pain Abnormal changes in your heart rhythm or your heart's electrical activity As part of some stress tests, pictures are taken of your heart while you exercise and while you rest. These imaging stress tests can show how well blood is flowing in various parts of your heart. They also can show how well your heart pumps blood when it beats. Chest X Ray A chest x ray takes pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels. A chest x ray can reveal signs of heart failure. It also can show signs of lung disorders and other causes of symptoms not related to CHD. However, a chest x ray alone is not enough to diagnose angina or CHD. Coronary Angiography and Cardiac Catheterization Your doctor may recommend coronary angiography (an-jee-OG-ra-fee) if he or she suspects you have CHD. This test uses dye and special x rays to show the inside of your coronary arteries. To get the dye into your coronary arteries, your doctor will use a procedure called cardiac catheterization (KATH-e-ter-ih-ZA-shun). A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream. Special x rays are taken while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels. Cardiac catheterization usually is done in a hospital. You're awake during the procedure. It usually causes little or no pain, although you may feel some soreness in the blood vessel where your doctor inserts the catheter. Computed Tomography Angiography Computed tomography (to-MOG-rah-fee) angiography (CTA) uses dye and special x rays to show blood flow through the coronary arteries. This test is less invasive than coronary angiography with cardiac catheterization. For CTA, a needle connected to an intravenous (IV) line is put into a vein in your hand or arm. Dye is injected through the IV line during the scan. You may have a warm feeling when this happens. The dye highlights your blood vessels on the CT scan pictures. Sticky patches called electrodes are put on your chest. The patches are attached to an EKG machine to record your heart's electrical activity during the scan. The CT scanner is a large machine that has a hollow, circular tube in the middle. You lie on your back on a sliding table. The table slowly slides into the opening of the machine. Inside the scanner, an x-ray tube moves around your body to take pictures of different parts of your heart. A computer puts the pictures together to make a three-dimensional (3D) picture of the whole heart. Blood Tests Blood tests check the levels of certain fats, cholesterol, sugar, and proteins in your blood. Abnormal levels may show that you have risk factors for CHD. Your doctor may recommend a blood test to check the level of a protein called C-reactive protein (CRP) in your blood. Some studies suggest that high levels of CRP in the blood may increase the risk for CHD and heart attack. Your doctor also may recommend a blood test to check for low levels of hemoglobin (HEE-muh-glow-bin) in your blood. Hemoglobin is an iron-rich protein in red blood cells. It helps the blood cells carry oxygen from the lungs to all parts of your body. If your hemoglobin level is low, you may have a condition called anemia (uh-NEE-me-uh).

### Question: What are the stages of Neuroblastoma ? ### Response:

Key Points - After neuroblastoma has been diagnosed, tests are done to find out if cancer has spread from where it started 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 neuroblastoma: - Stage 1 - Stage 2 - Stage 3 - Stage 4 - Treatment of neuroblastoma is based on risk groups. After neuroblastoma has been diagnosed, tests are done to find out if cancer has spread from where it started to other parts of the body. The process used to find out the extent or spread of cancer is called staging. The information gathered from the staging process helps determine the stage of the disease. For neuroblastoma, the stage of disease affects whether the cancer is low risk, intermediate risk, or high risk. It also affects the treatment plan. The results of some tests and procedures used to diagnose neuroblastoma may be used for staging. See the General Information section for a description of these tests and procedures. The following tests and procedures also may be used to determine the stage: - Lymph node biopsy : The removal of all or part of a lymph node. A pathologist views the tissue under a microscope to look for cancer cells. One of the following types of biopsies may be done: - Excisional biopsy : The removal of an entire lymph node. - Incisional biopsy : The removal of part of a lymph node. - Core biopsy : The removal of tissue from a lymph node using a wide needle. - Fine-needle aspiration (FNA) biopsy : The removal of tissue or fluid from a lymph node using a thin needle. - X-ray of the bone: An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. 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 neuroblastoma spreads to the liver, the cancer cells in the liver are actually neuroblastoma cells. The disease is metastatic neuroblastoma, not liver cancer. The following stages are used for neuroblastoma: Stage 1 In stage 1, the tumor is in only one area and all of the tumor that can be seen is completely removed during surgery. Stage 2 Stage 2 is divided into stages 2A and 2B. - Stage 2A: The tumor is in only one area and all of the tumor that can be seen cannot be completely removed during surgery. - Stage 2B: The tumor is in only one area and all of the tumor that can be seen may be completely removed during surgery. Cancer cells are found in the lymph nodes near the tumor. Stage 3 In stage 3, one of the following is true: - the tumor cannot be completely removed during surgery and has spread from one side of the body to the other side and may also have spread to nearby lymph nodes; or - the tumor is in only one area, on one side of the body, but has spread to lymph nodes on the other side of the body; or - the tumor is in the middle of the body and has spread to tissues or lymph nodes on both sides of the body, and the tumor cannot be removed by surgery. Stage 4 Stage 4 is divided into stages 4 and 4S. - In stage 4, the tumor has spread to distant lymph nodes or other parts of the body. - In stage 4S: - the child is younger than 12 months; and - the cancer has spread to the skin, liver, and/or bone marrow; and - the tumor is in only one area and all of the tumor that can be seen may be completely removed during surgery; and/or - cancer cells may be found in the lymph nodes near the tumor. Treatment of neuroblastoma is based on risk groups. For many types of cancer, stages are used to plan treatment. For neuroblastoma, treatment depends on risk groups. The stage of neuroblastoma is one factor used to determine risk group. Other factors are the age of the child, tumor histology, and tumor biology. There are three risk groups: low risk, intermediate risk, and high risk. - Low-risk and intermediate-risk neuroblastoma have a good chance of being cured. - High-risk neuroblastoma may be hard to cure.

### Question: How to diagnose Pulmonary Hypertension ? ### Response:

Your doctor will diagnose pulmonary hypertension (PH) based on your medical and family histories, a physical exam, and the results from tests and procedures. PH can develop slowly. In fact, you may have it for years and not know it. This is because the condition has no early signs or symptoms. When symptoms do occur, they're often like those of other heart and lung conditions, such as asthma. This makes PH hard to diagnose. Medical and Family Histories Your doctor may ask about your signs and symptoms and how and when they began. He or she also may ask whether you have other medical conditions that can cause PH. Your doctor will want to know whether you have any family members who have or have had PH. People who have a family history of PH are at higher risk for the condition. Physical Exam During the physical exam, your doctor will listen to your heart and lungs with a stethoscope. He or she also will check your ankles and legs for swelling and your lips and skin for a bluish color. These are signs of PH. Diagnostic Tests and Procedures Your doctor may recommend tests and procedures to confirm a diagnosis of PH and to look for its underlying cause. Your doctor also will use test results to find out the severity of your PH. Tests and Procedures To Confirm a Diagnosis Echocardiography. Echocardiography (EK-o-kar-de-OG-ra-fee), or echo, uses sound waves to create a moving picture of your heart. This test can estimate the pressure in your pulmonary arteries. Echo also can show the size and thickness of your right ventricle and how well it's working. Chest x ray. A chest x ray takes pictures of the structures in your chest, such as your heart, lungs, and blood vessels. This test can show whether your pulmonary arteries and right ventricle are enlarged. The pulmonary arteries and right ventricle may get larger if the right ventricle has to work hard to pump blood through the pulmonary arteries. A chest x ray also may show signs of an underlying lung disease that's causing or contributing to PH. EKG (electrocardiogram). An EKG is a simple, painless test that records the heart's electrical activity. This test also shows whether your heart's rhythm is steady or irregular. An EKG may show whether your right ventricle is enlarged or strained. Right heart catheterization. This procedure measures the pressure in your pulmonary arteries. It also shows how well your heart is pumping blood to the rest of your body. Right heart catheterization (KATH-e-ter-ih-ZA-shun) can find any leaks between the left and right side of the heart. During this procedure, a thin, flexible tube called a catheter is put into a blood vessel in your groin (upper thigh) or neck. The tube is threaded into the right side of your heart and into the pulmonary arteries. Through the tube, your doctor can do tests and treatments on your heart. Tests To Look for the Underlying Cause of Pulmonary Hypertension PH has many causes, so many tests may need to be done to find its underlying cause. Chest CT scan. A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, creates pictures of the structures inside your chest, such as your heart, lungs, and blood vessels. These pictures can show signs of PH or a condition that may be causing PH. Chest MRI. Chest magnetic resonance imaging, or chest MRI, shows how your right ventricle is working. The test also shows blood flow in your lungs. Chest MRI also can help detect signs of PH or an underlying condition causing PH. Lung function tests. Lung function tests measure how much air you can breathe in and out, how fast you can breathe air out, and how well your lungs deliver oxygen to your blood. These tests can help detect a lung disease that may be causing PH. Polysomnogram (PSG). This test records brain activity, eye movements, heart rate, and blood pressure while you sleep. A PSG also measures the level of oxygen in your blood. A low oxygen level during sleep is common in PH, and it can make the condition worse. A PSG usually is done while you stay overnight at a sleep center. For more information about this test, go to the Diseases and Conditions Index Sleep Studies article. Lung ventilation/perfusion (VQ) scan. A lung VQ scan measures air and blood flow in your lungs. This test can help detect blood clots in your lung's blood vessels. Blood tests. Blood tests are used to rule out other diseases, such as HIV, liver disease, and autoimmune diseases (such as rheumatoid arthritis). Finding Out the Severity of Pulmonary Hypertension Exercise testing is used to find out the severity of PH. This testing consists of either a 6-minute walk test or a cardiopulmonary exercise test. A 6-minute walk test measures the distance you can quickly walk in 6 minutes. A cardiopulmonary exercise test measures how well your lungs and heart work while you exercise on a treadmill or bicycle. During exercise testing, your doctor will rate your activity level. Your level is linked to the severity of your PH. The rating system ranges from class 1 to class 4. Class 1 has no limits. You can do regular physical activities, such as walking or climbing stairs. These activities don't cause PH symptoms, such as tiredness, shortness of breath, or chest pain. Class 2 has slight or mild limits. You're comfortable while resting, but regular physical activity causes PH symptoms. Class 3 has marked or noticeable limits. You're comfortable while resting. However, walking even one or two blocks or climbing one flight of stairs can cause PH symptoms. Class 4 has severe limits. You're not able to do any physical activity without discomfort. You also may have PH symptoms while at rest. Over time, you may need more exercise tests to find out how well your treatments are working. Each time testing is done, your doctor will compare your activity level with the previous one.

### Question: What are the treatments for Mineral and Bone Disorder in Chronic Kidney Disease ? ### Response:

Treating mineral and bone disorder in CKD includes preventing damage to bones by controlling parathyroid hormone levels through changes in eating, diet, and nutrition; medications and supplements; and dialysis. If these treatments do not bring parathyroid hormone levels under control, a health care provider may remove a persons parathyroid glands surgically, a procedure called a parathyroidectomy. Eating, Diet, and Nutrition Changes in diet can treat mineral and bone disorder in CKD. Reducing dietary intake of phosphorus is one of the most important steps in preventing bone disease. Most foods contain phosphorus; however, processed and packaged foods contain especially high levels of phosphorus. Food producers use phosphorus as an additive to preserve the food on the shelf. People who have CKD or are on dialysis should avoid packaged foods containing ingredients that include the letters PHOS. A renal dietitian can help develop a dietary plan to control phosphorus levels in the blood. Some drinks and natural foods also contain high amounts of phosphorus, including - beer - cheese - cocoa - dark sodas - dried beans - milk - nuts - peanut butter - peas More information is provided in the NIDDK health topics, How To Read a Food Label: Tips for People with Chronic Kidney Disease and Phosphorus: Tips for People with Chronic Kidney Disease. Medications and Supplements Medications protect the bones by restoring the proper balance of minerals and hormones. If the kidneys do not make adequate amounts of calcitriol, a health care provider may prescribe synthetic calcitriol as a pill (Rocaltrol) or, for dialysis patients, in an injectable form (Calcijex). Calcitriol helps reduce parathyroid hormone levels. Medications called doxercalciferol (Hectorol) and paricalcitol (Zemplar) act like calcitriol because they are also activated forms of vitamin D. A health care provider may prescribe a calcium supplement in addition to calcitriol or another activated form of vitamin D. Certain forms of vitamin Davailable by prescription or as over-the-counter vitamin supplementsrequire activation by a persons kidneys before they can act as calcitriol does. However, the benefits of some of these not-yet-activated forms of vitamin Dfor example, ergocalciferol (Calciferol, Drisdol) or cholecalciferol (Delta D3)are unclear. To help ensure coordinated and safe care, people should discuss their use of alternative medications, including use of vitamin and mineral supplements, with their health care provider. Cinacalcet hydrochloride (Sensipar) belongs to another class of prescription medications called calcimimetics. Cinacalcet lowers parathyroid hormone levels by imitating calciums effects on the parathyroid gland. Generally, this medication is used only in people on dialysis. Often, health care providers will prescribe medications called phosphate binderssuch as calcium carbonate (Tums), calcium acetate (PhosLo), sevelamer carbonate (Renvela), or lanthanum carbonate (Fosrenol)to take with meals and snacks to bind phosphorus in the bowel. These medications decrease the absorption of phosphorus into the blood. Dialysis Dialysis is the process of filtering wastes and extra fluid from the body by means other than the kidneys. The two forms of dialysis are hemodialysis and peritoneal dialysis: - Hemodialysis uses a machine to circulate a persons blood through a filter outside the body. The blood passes from a patients body through a needle, at nearly 1 pint per minute. The blood then travels through a tube that takes it to the filter, called a dialyzer. Inside the dialyzer, the blood flows through thin fibers that filter out wastes and extra fluid. After the machine filters the blood, it passes back to the body through another tube. More information is provided in the NIDDK health topic, Treatment Methods for Kidney Failure: Hemodialysis. - Peritoneal dialysis uses the lining of the abdomen to filter a persons blood inside the body. A soft tube called a catheter is placed in the patients abdomen a few weeks before peritoneal dialysis begins. A person uses the catheter to fill the empty space inside the abdomen with dialysis solutiona kind of salty waterfrom a plastic bag. While inside the body, the dialysis solution absorbs wastes and extra fluid. After a few hours, the person drains the used dialysis solution into another bag for disposal. The person then restarts the process with a fresh bag of dialysis solution. More information is provided in the NIDDK health topic, Treatment Methods for Kidney Failure: Peritoneal Dialysis. Increasing a persons dialysis dose can help control the blood phosphorus level. In hemodialysis, the health care provider can adjust the dose by increasing how quickly the blood flows to and from the dialyzer. Another way to adjust the dose involves increasing the time of a persons dialysis session or the number of sessions. In peritoneal dialysis, using more dialysis solution in each fill or increasing the number of fills each day increases the dose. More information is provided in the NIDDK health topics: - Hemodialysis Dose and Adequacy - Peritoneal Dialysis Dose and Adequacy Parathyroidectomy If diet, medications, and dialysis cant control parathyroid hormone levels, a surgeon can remove one or more of the parathyroid glands. He or she performs the procedure using general anesthesia. A good treatment program, including a low-phosphorus diet, appropriate medications, adequate dialysis, and, if necessary, surgery, can improve the bodys ability to repair bones damaged by mineral and bone disorder in CKD. Overall, people can improve their bone health by exercising and not smoking. People should consult a health care provider before beginning any exercise program.

### Question: How to diagnose Primary Biliary Cirrhosis ? ### Response:

A health care provider may use the following tests to diagnose primary biliary cirrhosis: - a medical and family history - a physical exam - blood tests - imaging tests - a liver biopsy A health care provider usually bases a diagnosis of primary biliary cirrhosis on two out of three of the following criteria: - a blood test showing elevated liver enzymes - a blood test showing the presence of anti-mitochondrial antibodies (AMA) - a liver biopsy showing signs of the disease Health care providers may order additional tests to rule out other causes of symptoms. Health care providers diagnose the majority of people with primary biliary cirrhosis early in the course of the disease. Medical and family history. Taking a medical and family history is one of the first things a health care provider may do to help diagnose primary biliary cirrhosis. He or she will ask a patient to provide a medical and family history. Physical exam. A physical exam may help diagnose primary biliary cirrhosis. During a physical exam, a health care provider usually - examines a patients body - uses a stethoscope to listen to sounds in the abdomen - taps on specific areas of the patients body The health care provider will perform a physical exam to look for signs of the disease. For example, the liver may feel hard or ascites may cause the abdomen to enlarge. Blood test. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can show elevated levels of liver enzymes, such as alkaline phosphatase. A routine blood test may show high levels of the liver enzyme alkaline phosphatase in people who have primary biliary cirrhosis and are not yet showing symptoms. The health care provider will perform an AMA blood test to help confirm the diagnosis. A blood test will detect the presence of AMA in 90 to 95 percent of people with primary biliary cirrhosis.3 Imaging tests. A health care provider may use the following imaging tests to examine the bile ducts. These tests can distinguish between primary biliary cirrhosis and other conditions that affect the bile ducts. - Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaging interprets the images. A patient does not need anesthesia. In addition to showing problems with the bile ducts, the images can show signs of advanced cirrhosis or complications. - Magnetic resonance cholangiopancreatography uses magnetic resonance imaging (MRI) to examine the bile ducts. MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. A specially trained technician performs magnetic resonance cholangiopancreatography in an outpatient center or a hospital, and a radiologist interprets the images. A patient does not need anesthesia, though a health care provider may use light sedation for patients with a fear of confined spaces. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines allow the patient to lie in a more open space. - Endoscopic retrograde cholangiopancreatography uses an x ray to look at the bile ducts. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. After lightly sedating the patient, the gastroenterologist inserts an endoscopea small, flexible tube with a light and a camera on the endthrough the mouth into the duodenum and bile ducts. The endoscope is connected to a computer and video monitor. The gastroenterologist injects a special dye, called contrast medium, through the tube into the bile ducts, which makes the ducts show up on the monitor. This test is more invasive than other imaging tests, and health care providers do not routinely need the test to make the diagnosis of primary biliary cirrhosis. A health care provider uses the test selectively when he or she is concerned that the blockage of the bile ducts has another cause, such as a gallstone or a narrowing of the large bile ducts due to inflammation or cancer. Patients may have pain, nausea, or vomiting after the test or may develop bacterial cholangitis or pancreatitisinflammation of the pancreas. Liver biopsy. A liver biopsy is a procedure that involves taking a piece of liver tissue for examination with a microscope for signs of damage or disease. The health care provider may ask the patient to stop taking certain medications temporarily before the liver biopsy. The health care provider may ask the patient to fast for 8 hours before the procedure. During the procedure, the patient lies on a table, right hand resting above the head. The health care provider applies a local anesthetic to the area where he or she will insert the biopsy needle. If needed, a health care provider will also give sedatives and pain medication. The health care provider uses a needle to take a small piece of liver tissue. He or she may use ultrasound, computerized tomography scans, or other imaging techniques to guide the needle. After the biopsy, the patient must lie on the right side for up to 2 hours and is monitored an additional 2 to 4 hours before being sent home. A health care provider performs a liver biopsy at a hospital or an outpatient center. The health care provider sends the liver sample to a pathology lab, where the pathologista doctor who specializes in diagnosing diseaseslooks at the tissue with a microscope and sends a report to the patients health care provider. A liver biopsy can confirm the diagnosis of primary biliary cirrhosis; however, a person does not always need this test. A health care provider will perform a biopsy if the AMA blood test is negative and the person shows other signs of primary biliary cirrhosis. Sometimes a health care provider finds a cause of liver damage other than primary biliary cirrhosis during biopsy.

### Question: What is (are) Childhood Central Nervous System Embryonal Tumors ? ### Response:

Key Points - Central nervous system (CNS) embryonal tumors may begin in embryonic (fetal) cells that remain in the brain after birth. - There are different types of CNS embryonal tumors. - Pineoblastomas form in cells of the pineal gland. - Certain genetic conditions increase the risk of childhood CNS embryonal tumors. - Signs and symptoms of childhood CNS embryonal tumors or pineoblastomas depend on the child's age and where the tumor is. - Tests that examine the brain and spinal cord are used to detect (find) childhood CNS embryonal tumors or pineoblastomas. - A biopsy may be done to be sure of the diagnosis of CNS embryonal tumor or pineoblastoma. - Certain factors affect prognosis (chance of recovery) and treatment options. Central nervous system (CNS) embryonal tumors may begin in embryonic (fetal) cells that remain in the brain after birth. Central nervous system (CNS) embryonal tumors form in embryonic cells that remain in the brain after birth. CNS embryonal tumors tend to spread through the cerebrospinal fluid (CSF) to other parts of the brain and spinal cord. The tumors may be malignant (cancer) or benign (not cancer). Most CNS embryonal tumors in children are malignant. Malignant brain tumors are likely to grow quickly and spread into other parts of the brain. When a tumor grows into or presses on an area of the brain, it may stop that part of the brain from working the way it should. Benign brain tumors grow and press on nearby areas of the brain. They rarely spread to other parts of the brain. Both benign and malignant brain tumors can cause signs or symptoms and need treatment. Although cancer is rare in children, brain tumors are the third most common type of childhood cancer, after leukemia and lymphoma. This summary is about the treatment of primary brain tumors (tumors that begin in the brain). The treatment of metastatic brain tumors, which begin in other parts of the body and spread to the brain, is not discussed in this summary. For information about the different types of brain and spinal cord tumors, see the PDQ summary on Childhood Brain and Spinal Cord Tumors Treatment Overview. Brain tumors occur in both children and adults. Treatment for adults may be different from treatment for children. See the PDQ summary on Adult Central Nervous System Tumors Treatment for more information on the treatment of adults. There are different types of CNS embryonal tumors. The different types of CNS embryonal tumors include: - Medulloblastomas Most CNS embryonal tumors are medulloblastomas. Medulloblastomas are fast-growing tumors that form in brain cells in the cerebellum. The cerebellum is at the lower back part of the brain between the cerebrum and the brain stem. The cerebellum controls movement, balance, and posture. Medulloblastomas sometimes spread to the bone, bone marrow, lung, or other parts of the body, but this is rare. - Nonmedulloblastoma embryonal tumors Nonmedulloblastoma embryonal tumors are fast-growing tumors that usually form in brain cells in the cerebrum. The cerebrum is at the top of the head and is the largest part of the brain. The cerebrum controls thinking, learning, problem-solving, emotions, speech, reading, writing, and voluntary movement. Nonmedulloblastoma embryonal tumors may also form in the brain stem or spinal cord. There are four types of nonmedulloblastoma embryonal tumors: - Embryonal tumors with multilayered rosettes Embryonal tumors with multilayered rosettes (ETMR) are rare tumors that form in the brain and spinal cord. ETMR most commonly occur in young children and are fast-growing tumors. - Medulloepitheliomas Medulloepitheliomas are fast-growing tumors that usually form in the brain, spinal cord or nerves just outside the spinal column. They occur most often in infants and young children. - CNS neuroblastomas CNS neuroblastomas are a very rare type of neuroblastoma that form in the nerve tissue of the cerebrum or the layers of tissue that cover the brain and spinal cord. CNS neuroblastomas may be large and spread to other parts of the brain or spinal cord. - CNS ganglioneuroblastomas CNS ganglioneuroblastomas are rare tumors that form in nerve tissue of the brain and spinal cord. They may form in one area and be fast growing or form in more than one area and be slow growing. Childhood CNS atypical teratoid/rhabdoid tumor is also a type of embryonal tumor, but it is treated differently than other childhood CNS embryonal tumors. See the PDQ summary on Childhood Central Nervous System Atypical Teratoid/Rhabdoid Tumor Treatment for more information. Pineoblastomas form in cells of the pineal gland. The pineal gland is a tiny organ in the center of the brain. The gland makes melatonin, a substance that helps control our sleep cycle. Pineoblastomas form in cells of the pineal gland and are usually malignant. Pineoblastomas are fast-growing tumors with cells that look very different from normal pineal gland cells. Pineoblastomas are not a type of CNS embryonal tumor but treatment for them is a lot like treatment for CNS embryonal tumors. Pineoblastoma is linked with inherited changes in the retinoblastoma (RB1) gene. A child with the inherited form of retinoblastoma (cancer than forms in the tissues of the retina) has an increased risk of pineoblastoma. When retinoblastoma forms at the same time as a tumor in or near the pineal gland, it is called trilateral retinoblastoma. MRI (magnetic resonance imaging) testing in children with retinoblastoma may detect pineoblastoma at an early stage when it can be treated successfully.

### Question: How to diagnose Pancreatic Cancer ? ### Response:

Tests that examine the pancreas are used to detect (find), diagnose, and stage pancreatic cancer. Pancreatic cancer is usually diagnosed with tests and procedures that make pictures of the pancreas and the area around it. The process used to find out if cancer cells have spread within and around the pancreas is called staging. Tests and procedures to detect, diagnose, and stage pancreatic cancer are usually done at the same time. In order to plan treatment, it is important to know the stage of the disease and whether or not the pancreatic cancer can be removed by surgery. 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. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances, such as bilirubin, released into the blood by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Tumor marker test : A procedure in which a sample of blood, urine, or tissue is checked to measure the amounts of certain substances, such as CA 19-9, and carcinoembryonic antigen (CEA), made by organs, tissues, or tumor cells in the body. Certain substances are linked to specific types of cancer when found in increased levels in the body. These are called tumor markers. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (NMRI). - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. A spiral or helical CT scan makes a series of very detailed pictures of areas inside the body using an x-ray machine that scans the body in a spiral path. - PET scan (positron emission tomography scan): A procedure to find malignant tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Malignant tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. A PET scan and CT scan may be done at the same time. This is called a PET-CT. - Abdominal ultrasound : An ultrasound exam used to make pictures of the inside of the abdomen. The ultrasound transducer is pressed against the skin of the abdomen and directs high-energy sound waves (ultrasound) into the abdomen. The sound waves bounce off the internal tissues and organs and make echoes. The transducer receives the echoes and sends them to a computer, which uses the echoes to make pictures called sonograms. The picture can be printed to be looked at later. - Endoscopic ultrasound (EUS): A procedure in which an endoscope is inserted into the body, usually through the mouth or rectum. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. A probe at the end of the endoscope is used to bounce high-energy sound waves (ultrasound) off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. This procedure is also called endosonography. - Endoscopic retrograde cholangiopancreatography (ERCP): A procedure used to x-ray the ducts (tubes) that carry bile from the liver to the gallbladder and from the gallbladder to the small intestine. Sometimes pancreatic cancer causes these ducts to narrow and block or slow the flow of bile, causing jaundice. An endoscope (a thin, lighted tube) is passed through the mouth, esophagus, and stomach into the first part of the small intestine. A catheter (a smaller tube) is then inserted through the endoscope into the pancreatic ducts. A dye is injected through the catheter into the ducts and an x-ray is taken. If the ducts are blocked by a tumor, a fine tube may be inserted into the duct to unblock it. This tube (or stent) may be left in place to keep the duct open. Tissue samples may also be taken. - Percutaneous transhepatic cholangiography (PTC): A procedure used to x-ray the liver and bile ducts. A thin needle is inserted through the skin below the ribs and into the liver. Dye is injected into the liver or bile ducts and an x-ray is taken. If a blockage is found, a thin, flexible tube called a stent is sometimes left in the liver to drain bile into the small intestine or a collection bag outside the body. This test is done only if ERCP cannot be done. - Laparoscopy : A surgical procedure to look at the organs inside the abdomen to check for signs of disease. Small incisions (cuts) are made in the wall of the abdomen and a laparoscope (a thin, lighted tube) is inserted into one of the incisions. The laparoscope may have an ultrasound probe at the end in order to bounce high-energy sound waves off internal organs, such as the pancreas. This is called laparoscopic ultrasound. Other instruments may be inserted through the same or other incisions to perform procedures such as taking tissue samples from the pancreas or a sample of fluid from the abdomen to check for cancer. - Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer. There are several ways to do a biopsy for pancreatic cancer. A fine needle or a core needle may be inserted into the pancreas during an x-ray or ultrasound to remove cells. Tissue may also be removed during a laparoscopy.

### Question: What is (are) Gestational Trophoblastic Disease ? ### Response:

Key Points - Gestational trophoblastic disease (GTD) is a group of rare diseases in which abnormal trophoblast cells grow inside the uterus after conception. - Hydatidiform mole (HM) is the most common type of GTD. - Gestational trophoblastic neoplasia (GTN) is a type of gestational trophoblastic disease (GTD) that is almost always malignant. - Invasive moles - Choriocarcinomas - Placental-site trophoblastic tumors - Epithelioid trophoblastic tumors - Age and a previous molar pregnancy affect the risk of GTD. - Signs of GTD include abnormal vaginal bleeding and a uterus that is larger than normal. - Tests that examine the uterus are used to detect (find) and diagnose gestational trophoblastic disease. - Certain factors affect prognosis (chance of recovery) and treatment options. Gestational trophoblastic disease (GTD) is a group of rare diseases in which abnormal trophoblast cells grow inside the uterus after conception. In gestational trophoblastic disease (GTD), a tumor develops inside the uterus from tissue that forms after conception (the joining of sperm and egg). This tissue is made of trophoblast cells and normally surrounds the fertilized egg in the uterus. Trophoblast cells help connect the fertilized egg to the wall of the uterus and form part of the placenta (the organ that passes nutrients from the mother to the fetus). Sometimes there is a problem with the fertilized egg and trophoblast cells. Instead of a healthy fetus developing, a tumor forms. Until there are signs or symptoms of the tumor, the pregnancy will seem like a normal pregnancy. Most GTD is benign (not cancer) and does not spread, but some types become malignant (cancer) and spread to nearby tissues or distant parts of the body. Gestational trophoblastic disease (GTD) is a general term that includes different types of disease: - Hydatidiform Moles (HM) - Complete HM. - Partial HM. - Gestational Trophoblastic Neoplasia (GTN) - Invasive moles. - Choriocarcinomas. - Placental-site trophoblastic tumors (PSTT; very rare). - Epithelioid trophoblastic tumors (ETT; even more rare). Hydatidiform mole (HM) is the most common type of GTD. HMs are slow-growing tumors that look like sacs of fluid. An HM is also called a molar pregnancy. The cause of hydatidiform moles is not known. HMs may be complete or partial: - A complete HM forms when sperm fertilizes an egg that does not contain the mothers DNA. The egg has DNA from the father and the cells that were meant to become the placenta are abnormal. - A partial HM forms when sperm fertilizes a normal egg and there are two sets of DNA from the father in the fertilized egg. Only part of the fetus forms and the cells that were meant to become the placenta are abnormal. Most hydatidiform moles are benign, but they sometimes become cancer. Having one or more of the following risk factors increases the risk that a hydatidiform mole will become cancer: - A pregnancy before 20 or after 35 years of age. - A very high level of beta human chorionic gonadotropin (-hCG), a hormone made by the body during pregnancy. - A large tumor in the uterus. - An ovarian cyst larger than 6 centimeters. - High blood pressure during pregnancy. - An overactive thyroid gland (extra thyroid hormone is made). - Severe nausea and vomiting during pregnancy. - Trophoblastic cells in the blood, which may block small blood vessels. - Serious blood clotting problems caused by the HM. Gestational trophoblastic neoplasia (GTN) is a type of gestational trophoblastic disease (GTD) that is almost always malignant. Gestational trophoblastic neoplasia (GTN) includes the following: Invasive moles Invasive moles are made up of trophoblast cells that grow into the muscle layer of the uterus. Invasive moles are more likely to grow and spread than a hydatidiform mole. Rarely, a complete or partial HM may become an invasive mole. Sometimes an invasive mole will disappear without treatment. Choriocarcinomas A choriocarcinoma is a malignant tumor that forms from trophoblast cells and spreads to the muscle layer of the uterus and nearby blood vessels. It may also spread to other parts of the body, such as the brain, lungs, liver, kidney, spleen, intestines, pelvis, or vagina. A choriocarcinoma is more likely to form in women who have had any of the following: - Molar pregnancy, especially with a complete hydatidiform mole. - Normal pregnancy. - Tubal pregnancy (the fertilized egg implants in the fallopian tube rather than the uterus). - Miscarriage. Placental-site trophoblastic tumors A placental-site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia that forms where the placenta attaches to the uterus. The tumor forms from trophoblast cells and spreads into the muscle of the uterus and into blood vessels. It may also spread to the lungs, pelvis, or lymph nodes. A PSTT grows very slowly and signs or symptoms may appear months or years after a normal pregnancy. Epithelioid trophoblastic tumors An epithelioid trophoblastic tumor (ETT) is a very rare type of gestational trophoblastic neoplasia that may be benign or malignant. When the tumor is malignant, it may spread to the lungs.

### Question: What are the stages of Retinoblastoma ? ### Response:

Key Points - After retinoblastoma has been diagnosed, tests are done to find out if cancer cells have spread within the eye or to other parts of the body. - The International Retinoblastoma Staging System (IRSS) may be used for staging retinoblastoma. - Stage 0 - Stage I - Stage II - Stage III - Stage IV - There are three ways that cancer spreads in the body. - Cancer may spread from where it began to other parts of the body. - Treatment for retinoblastoma depends on whether it is intraocular (within the eye) or extraocular (outside the eye). - Intraocular retinoblastoma - Extraocular retinoblastoma (metastatic) After retinoblastoma has been diagnosed, tests are done to find out if cancer cells have spread within the eye or to other parts of the body. The process used to find out if cancer has spread within the eye or to other parts of the body is called staging. The information gathered from the staging process determines whether retinoblastoma is only in the eye (intraocular) or has spread outside the eye (extraocular). 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.) The following tests and procedures may be used in the staging process: - Bone scan : A procedure to check if there are rapidly dividing cells, such as cancer cells, in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones and is detected by a scanner that also takes a picture of the body. Areas of bone with cancer show up brighter in the picture because they take up more radioactive material than normal bone cells do. - Bone marrow aspiration and biopsy : The removal of bone marrow and a small piece of bone by inserting a hollow needle into the hipbone or breastbone. A pathologist views the bone marrow under a microscope to look for signs of cancer. A bone marrow aspiration and biopsy is done if the doctor thinks the cancer has spread outside of the eye. - Lumbar puncture : A procedure used to collect cerebrospinal fluid (CSF) from the spinal column. This is done by placing a needle between two bones in the spine and into the CSF around the spinal cord and removing a sample of the fluid. The sample of CSF is checked under a microscope for signs that the cancer has spread to the brain and spinal cord. This procedure is also called an LP or spinal tap. The International Retinoblastoma Staging System (IRSS) may be used for staging retinoblastoma. There are several staging systems for retinoblastoma. The IRSS stages are based on how much cancer remains after surgery to remove the tumor and whether the cancer has spread. Stage 0 The tumor is in the eye only. The eye has not been removed and the tumor was treated without surgery. Stage I The tumor is in the eye only. The eye has been removed and no cancer cells remain. Stage II The tumor is in the eye only. The eye has been removed and there are cancer cells left that can be seen only with a microscope. Stage III Stage III is divided into stages IIIa and IIIb: - In stage IIIa, cancer has spread from the eye to tissues around the eye socket. - In stage IIIb, cancer has spread from the eye to lymph nodes near the ear or in the neck. Stage IV Stage IV is divided into stages IVa and IVb: - In stage IVa, cancer has spread to the blood but not to the brain or spinal cord. One or more tumors may have spread to other parts of the body such as the bone or liver. - In stage IVb, cancer has spread to the brain or spinal cord. It also may have spread to other parts of the body. 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 retinoblastoma spreads to the bone, the cancer cells in the bone are actually retinoblastoma cells. The disease is metastatic retinoblastoma, not bone cancer. Treatment for retinoblastoma depends on whether it is intraocular (within the eye) or extraocular (outside the eye). Intraocular retinoblastoma In intraocular retinoblastoma, cancer is found in one or both eyes and may be in the retina only or may also be in other parts of the eye such as the choroid, ciliary body, or part of the optic nerve. Cancer has not spread to tissues around the outside of the eye or to other parts of the body. Extraocular retinoblastoma (metastatic) In extraocular retinoblastoma, cancer has spread beyond the eye. It may be found in tissues around the eye (orbital retinoblastoma) or it may have spread to the central nervous system (brain and spinal cord) or to other parts of the body such as the liver, bones, bone marrow, or lymph nodes.

### Question: How to diagnose Langerhans Cell Histiocytosis ? ### Response:

The following tests and procedures may be used to detect (find) and diagnose LCH or conditions caused by LCH: - 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 patient's health habits and past illnesses and treatments will also be taken. - Neurological exam : A series of questions and tests to check the brain, spinal cord, and nerve function. The exam checks a person's mental status, coordination, and ability to walk normally, and how well the muscles, senses, and reflexes work. This may also be called a neuro exam or a neurologic exam. - Complete blood count (CBC) with differential : A procedure in which a sample of blood is drawn and checked for the following: - 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. - The number and type of white blood cells. - The number of red blood cells and platelets. - Blood chemistry studies : A procedure in which a blood sample is checked to measure the amounts of certain substances released into the body by organs and tissues in the body. An unusual (higher or lower than normal) amount of a substance can be a sign of disease. - Liver function test : A blood test to measure the blood levels of certain substances released by the liver. A high or low level of these substances can be a sign of disease in the liver. - BRAF gene testing : A laboratory test in which a sample of blood or tissue is tested for mutations of the BRAF gene. - Urinalysis : A test to check the color of urine and its contents, such as sugar, protein, red blood cells, and white blood cells. - Water deprivation test : A test to check how much urine is made and whether it becomes concentrated when little or no water is given. This test is used to diagnose diabetes insipidus, which may be caused by LCH. - Bone marrow aspiration and biopsy : The removal of bone marrow and a small piece of bone by inserting a hollow needle into the hipbone. A pathologist views the bone marrow and bone under a microscope to look for signs of LCH. The following tests may be done on the tissue that was removed: - Immunohistochemistry : A test that uses antibodies to check for certain antigens in a sample of tissue. The antibody is usually linked to a radioactive substance or a dye that causes the tissue to light up under a microscope. This type of test may be used to tell the difference between different types of cancer. - Flow cytometry : A laboratory test that measures the number of cells in a sample, how many cells are live, and the size of the cells. It also shows the shapes of the cells and whether there are tumor markers on the surface of the cells. 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. - Bone scan : A procedure to check if there are rapidly dividing cells in the bone. A very small amount of radioactive material is injected into a vein and travels through the bloodstream. The radioactive material collects in the bones with cancer and is detected by a scanner. - X-ray : An x-ray of the organs and bones inside the body. An x-ray is a type of energy beam that can go through the body and onto film, making a picture of areas inside the body. Sometimes a skeletal survey is done. This is a procedure to x-ray all of the bones in the body. - CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium may be injected into a vein. The gadolinium collects around the LCH cells so that they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI). - PET scan (positron emission tomography scan): A procedure to find tumor cells in the body. A small amount of radioactive glucose (sugar) is injected into a vein. The PET scanner rotates around the body and makes a picture of where glucose is being used in the body. Tumor cells show up brighter in the picture because they are more active and take up more glucose than normal cells do. - Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed to be looked at later. - Bronchoscopy : A procedure to look inside the trachea and large airways in the lung for abnormal areas. A bronchoscope is inserted through the nose or mouth into the trachea and lungs. A bronchoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue samples, which are checked under a microscope for signs of cancer. - Endoscopy : A procedure to look at organs and tissues inside the body to check for abnormal areas in the gastrointestinal tract or lungs. An endoscope is inserted through an incision (cut) in the skin or opening in the body, such as the mouth. An endoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue or lymph node samples, which are checked under a microscope for signs of disease. - Biopsy : The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for LCH cells. To diagnose LCH, a biopsy of bone lesions, skin, lymph nodes, or the liver may be done.

### Question: What causes Skin Cancer ? ### Response:

Scientists have been able to identify the causes and risk factors for skin cancer. A risk factor is anything that increases your chances of getting a disease. DNA Damage One of the main reasons that skin cancer develops is because DNA is damaged. DNA is the master molecule that controls and directs every cell in the body. Damage to DNA is one of the ways that cells lose control of growth and become cancerous. DNA mutations can also be inherited. Exposure to Ultraviolet Radiation Excess exposure to ultraviolet (UV) light can damage the DNA in skin cells and increase a person's risk for both melanoma and non-melanoma skin cancer. UV light is invisible radiation from the sun that can damage DNA. Skin cells are especially susceptible to DNA damage since they are frequently exposed to UV light. There are three types of UV radiation: A, B, and C. All three are dangerous and able to penetrate skin cells. UVA is the most common on earth, and is harmful to the skin. UVB is less common because some of it is absorbed by the ozone layer. It is less harmful than UVA, but can still cause damage. UVC is the least dangerous because although it can cause the most damage to the skin, almost all of the UVC rays are absorbed by the ozone layer. Sources of Ultraviolet Radiation UV radiation comes from the sun, sunlamps, tanning beds, or tanning booths. UV radiation is present even in cold weather or on a cloudy day. A person's risk of skin cancer is related to lifetime exposure to UV radiation. Most skin cancer appears after age 50, but the sun damages the skin from an early age. The body has systems to repair DNA and control some mutations, but not all of them. The risk of cancer increases as we age because sometimes cancer is caused by many mutations accumulating over time. Role of the Immune System The body's immune system is also responsible for recognizing and killing abnormal cells before they become cancerous. As we get older, our immune systems are less able to fight infection and control cell growth. People whose immune system is weakened by certain other cancers, medications, or by HIV are at an increased risk of developing skin cancer. Basal Cell and Squamous Cell Carcinoma Besides risk factors that increase a person's chance of getting any type of skin cancer, there are risk factors that are specific to basal cell carcinoma and squamous cell carcinoma, the non-melanoma skin cancers. These risk factors include - scars or burns on the skin - chronic skin inflammation or skin ulcers - infection with certain human papilloma viruses - exposure to arsenic at work - radiation therapy - diseases that make the skin sensitive to the sun, such as xeroderma pigmentosum, albinism, and basal cell nevus syndrome - medical conditions or drugs that suppress the immune system - personal history of one or more skin cancers - family history of skin cancer - certain diseases of the skin, including actinic keratosis and Bowen's disease. scars or burns on the skin chronic skin inflammation or skin ulcers infection with certain human papilloma viruses exposure to arsenic at work radiation therapy diseases that make the skin sensitive to the sun, such as xeroderma pigmentosum, albinism, and basal cell nevus syndrome medical conditions or drugs that suppress the immune system personal history of one or more skin cancers family history of skin cancer certain diseases of the skin, including actinic keratosis and Bowen's disease. Someone who has one or more of these risk factors has a greater chance of getting skin cancer than someone who does not have these risk factors. However, having these risk factors does not guarantee a person will get skin cancer. Many genetic and environmental factors play a role in causing cancer. Melanoma Melanoma is less common than non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma, but it is more serious. The factors that increase a person's chance of getting melanoma are - severe, blistering sunburns earlier in life - unusual moles (normally benign clusters of melanocytes) - large quantity of ordinary moles (more than 50) - white or light-colored (fair) skin, especially with freckles. - blond or red hair - blue or green eyes - being older than 20 years of age. severe, blistering sunburns earlier in life unusual moles (normally benign clusters of melanocytes) large quantity of ordinary moles (more than 50) white or light-colored (fair) skin, especially with freckles. blond or red hair blue or green eyes being older than 20 years of age. Someone who has one or more of these risk factors has a greater chance of getting melanoma than someone who does not have these risk factors. However, having these risk factors does not guarantee a person will get cancer. Many genetic and environmental factors play a role in causing cancer. Reducing Your Risk While exposure to UV radiation is a major risk factor for cancer, skin cancer can occur anywhere on the skin, not just in sun-exposed areas. The best ways to reduce your risk of skin cancer are to - avoid outdoor activities during midday, when the sun's rays are strongest - wear protective clothing such as a wide-brimmed hat, long-sleeved shirt, and pants. avoid outdoor activities during midday, when the sun's rays are strongest wear protective clothing such as a wide-brimmed hat, long-sleeved shirt, and pants. Darker-colored clothing is more protective against the sun. For example, a white t-shirt, particularly if it gets wet, provides little resistance to UV rays. In addition, wearing sunglasses that wrap around the face or have large frames is a good way to shield the delicate skin around the eyes. Wear Sunscreen and Lipscreen When exposed to sunlight, you should always wear sunscreen and lipscreen. If possible, choose sunscreen and lipscreen labeled "broad-spectrum" (to protect against UVA and UVB rays). Your sunscreen should have an SPF, or sun protection rating, of at least 15. The SPF of a sunscreen is a measure of the time it takes to produce a sunburn in a person wearing sunscreen compared to the time it takes to produce a sunburn in a person not wearing sunscreen. This varies from person to person, so be sure to reapply sunscreen every 2-3 hours.

### Question: What are the treatments for Overview of Kidney Disease in Children ? ### Response:

Treatment for kidney disease in children depends on the cause of the illness. A child may be referred to a pediatric nephrologista doctor who specializes in treating kidney diseases and kidney failure in childrenfor treatment. Children with a kidney disease that is causing high blood pressure may need to take medications to lower their blood pressure. Improving blood pressure can significantly slow the progression of kidney disease. The health care provider may prescribe - angiotensin-converting enzyme (ACE) inhibitors, which help relax blood vessels and make it easier for the heart to pump blood - angiotensin receptor blockers (ARBs), which help relax blood vessels and make it easier for the heart to pump blood - diuretics, medications that increase urine output Many children require two or more medications to control their blood pressure; other types of blood pressure medications may also be needed. As kidney function declines, children may need treatment for anemia and growth failure. Anemia is treated with a hormone called erythropoietin, which stimulates the bone marrow to produce red blood cells. Children with growth failure may need to make dietary changes and take food supplements or growth hormone injections. Children with kidney disease that leads to kidney failure must receive treatment to replace the work the kidneys do. The two types of treatment are dialysis and transplantation. More information is provided in the NIDDK health topic, Treatment Methods for Kidney Failure in Children. Birth Defects Children with renal agenesis or renal dysplasia should be monitored for signs of kidney damage. Treatment is not needed unless damage to the kidney occurs. More information is provided in the NIDDK health topic, Solitary Kidney. Ectopic kidney does not need to be treated unless it causes a blockage in the urinary tract or damage to the kidney. When a blockage is present, surgery may be needed to correct the position of the kidney for better drainage of urine. If extensive kidney damage has occurred, surgery may be needed to remove the kidney. More information is provided in the NIDDK health topic, Ectopic Kidney. Hereditary Diseases Children with PKD tend to have frequent urinary tract infections, which are treated with bacteria-fighting medications called antibiotics. PKD cannot be cured, so children with the condition receive treatment to slow the progression of kidney disease and treat the complications of PKD. More information is provided in the NIDDK health topic, Polycystic Kidney Disease. Alport syndrome also has no cure. Children with the condition receive treatment to slow disease progression and treat complications until the kidneys fail. More information is provided in the NIDDK health topic, Glomerular Diseases. Infection Treatment for hemolytic uremic syndrome includes maintaining normal salt and fluid levels in the body to ease symptoms and prevent further problems. A child may need a transfusion of red blood cells delivered through an intravenous (IV) tube. Some children may need dialysis for a short time to take over the work the kidneys usually do. Most children recover completely with no long-term consequences. More information is provided in the NIDDK health topic, Hemolytic Uremic Syndrome in Children. Children with post-streptococcal glomerulonephritis may be treated with antibiotics to destroy any bacteria that remain in the body and with medications to control swelling and high blood pressure. They may also need dialysis for a short period of time. More information about post-streptococcal glomerulonephritis is provided in the NIDDK health topic, Glomerular Diseases. Nephrotic Syndrome Nephrotic syndrome due to minimal change disease can often be successfully treated with corticosteroids. Corticosteroids decrease swelling and reduce the activity of the immune system. The dosage of the medication is decreased over time. Relapses are common; however, they usually respond to treatment. Corticosteroids are less effective in treating nephrotic syndrome due to focal segmental glomerulosclerosis or membranoproliferative glomerulonephritis. Children with these conditions may be given other immunosuppressive medications in addition to corticosteroids. Immunosuppressive medications prevent the body from making antibodies. More information is provided in the NIDDK health topic, Childhood Nephrotic Syndrome. Systemic Diseases Lupus nephritis is treated with corticosteroids and other immunosuppressive medications. A child with lupus nephritis may also be treated with blood pressure-lowering medications. In many cases, treatment is effective in completely or partially controlling lupus nephritis. More information is provided in the NIDDK health topic, Lupus Nephritis. Diabetic kidney disease usually takes many years to develop. Children with diabetes can prevent or slow the progression of diabetic kidney disease by taking medications to control high blood pressure and maintaining normal blood glucose levels. More information is provided in the NIDDK health topic, Kidney Disease of Diabetes. Trauma The types of trauma described above can be medically treated, though dialysis may be needed for a short time until blood flow and blood pressure return to normal. Urine Blockage and Reflux Treatment for urine blockage depends on the cause and severity of the blockage. In some cases, the blockage goes away without treatment. For children who continue to have urine blockage, surgery may be needed to remove the obstruction and restore urine flow. After surgery, a small tube, called a stent, may be placed in the ureter or urethra to keep it open temporarily while healing occurs. More information is provided in the NIDDK health topic, Urine Blockage in Newborns. Treatment for reflux may include prompt treatment of urinary tract infections and long-term use of antibiotics to prevent infections until reflux goes away on its own. Surgery has also been used in certain cases. More information is provided in the NIDDK health topic, Vesicoureteral Reflux.

### Question: How to diagnose Urinary Tract Infection In Adults ? ### Response:

To find out whether a person has a UTI, the health care provider will ask about urinary symptoms and then test a sample of urine for the presence of bacteria and white blood cells, which are produced by the body to fight infection. Because bacteria can be found in the urine of healthy individuals, a UTI is diagnosed based both on symptoms and a laboratory test. The person will be asked to give a clean catch urine sample by washing the genital area and collecting a midstream sample of urine in a sterile container. This method of collecting urine helps prevent bacteria around the genital area from getting into the sample and confusing the test results. Usually, the sample is sent to a laboratory, although some health care providers offices are equipped to do the testing. For people with recurring infections and patients in the hospital, the urine may be cultured. The culture is performed by placing part of the urine sample in a tube or dish with a substance that encourages any bacteria present to grow. Once the bacteria have multiplied, which usually takes 1 to 3 days, they can be identified. The health care provider may also order a sensitivity test, which tests the bacteria for sensitivity to different antibiotics to see which medication is best for treating the infection. If a person has recurrent UTIs, the health care provider may order some additional tests to determine if the persons urinary tract is normal. Kidney and bladder ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging; anesthesia is not needed. The images can show abnormalities in the kidneys and bladder. However, this test cannot reveal all important urinary abnormalities or measure how well the kidneys work. Voiding cystourethrogram. This test is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. As the person lies on the x-ray table, a health care provider inserts the tip of a thin, flexible tube called a catheter through the urethra into the bladder. The bladder and urethra are filled with a special dye called contrast medium, to make the structures clearly visible on the x-ray images. The x rays are taken from various angles while the bladder is full of contrast medium. The catheter is then removed and x-ray images are taken during urination. The procedure is performed in a health care providers office, outpatient center, or hospital by an x-ray technician. The technician is supervised by a radiologist while the images are taken. The radiologist then interprets the images. Anesthesia is not needed, but light sedation may be used for some people. This test can show abnormalities of the inside of the urethra and bladder. The test can also determine whether the flow of urine is normal when the bladder empties. Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. The procedure is performed in an outpatient center or hospital by an x-ray technician, and the images are interpreted by a radiologist; anesthesia is not needed. CT scans can provide clearer, more detailed images to help the health care provider understand the problem. Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include an injection of contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed though light sedation may be used for people with a fear of confined spaces. Like CT scans, MRIs can provide clearer, more detailed images. Radionuclide scan. A radionuclide scan is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive chemicals. Because the dose of the radioactive chemicals is small, the risk of causing damage to cells is low. Special cameras and computers are used to create images of the radioactive chemicals as they pass through the kidneys. Radionuclide scans are performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed. Radioactive chemicals injected into the blood can provide information about kidney function. Radioactive chemicals can also be put into the fluids used to fill the bladder and urethra for x ray, MRI, and CT imaging. Urodynamics. Urodynamic testing is any procedure that looks at how well the bladder, sphincters, and urethra are storing and releasing urine. Most of these tests are performed in the office of a urologista doctor who specializes in urinary problemsby a urologist, physician assistant, or nurse practitioner. Some procedures may require light sedation to keep a person calm. Most urodynamic tests focus on the bladders ability to hold urine and empty steadily and completely. Urodynamic tests can also show whether the bladder is having abnormal contractions that cause leakage. A health care provider may order these tests if there is evidence that the person has some kind of nerve damage. Cystoscopy. Cystoscopy is a procedure that uses a tubelike instrument to look inside the urethra and bladder. Cystoscopy is performed by a doctor in a health care providers office, outpatient facility, or hospital with local anesthesia. However, in some cases, sedation and regional or general anesthesia are needed. Cystoscopy may be used to look for swelling, redness, and other signs of infection.

### Question: What causes Causes of Diabetes ? ### Response:

Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time. Type 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus. Latent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels. Genetic Susceptibility Heredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants. Certain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk. While HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention. Genetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment. Autoimmune Destruction of Beta Cells In type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research. Recent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes. Environmental Factors Environmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis. Viruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease. Infant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.

### Question: How to diagnose Idiopathic Pulmonary Fibrosis ? ### Response:

Idiopathic pulmonary fibrosis (IPF) causes the same kind of scarring and symptoms as some other lung diseases. This makes it hard to diagnose. Seeking medical help as soon as you have symptoms is important. If possible, seek care from a pulmonologist. This is a doctor who specializes in diagnosing and treating lung problems. Your doctor will diagnose IPF based on your medical history, a physical exam, and test results. Tests can help rule out other causes of your symptoms and show how badly your lungs are damaged. Medical History Your doctor may ask about: Your age Your history of smoking Things in the air at your job or elsewhere that could irritate your lungs Your hobbies Your history of legal and illegal drug use Other medical conditions that you have Your family's medical history How long you've had symptoms Diagnostic Tests No single test can diagnose IPF. Your doctor may recommend several of the following tests. Chest X Ray A chest x ray is a painless test that creates a picture of the structures in your chest, such as your heart and lungs. This test can show shadows that suggest scar tissue. However, many people who have IPF have normal chest x rays at the time they're diagnosed. High-Resolution Computed Tomography A high-resolution computed tomography scan, or HRCT scan, is an x ray that provides sharper and more detailed pictures than a standard chest x ray. HRCT can show scar tissue and how much lung damage you have. This test can help your doctor spot IPF at an early stage or rule it out. HRCT also can help your doctor decide how likely you are to respond to treatment. Lung Function Tests Your doctor may suggest a breathing test called spirometry(spi-ROM-eh-tree) to find out how much lung damage you have. This test measures how much air you can blow out of your lungs after taking a deep breath. Spirometry also measures how fast you can breathe the air out. If you have a lot of lung scarring, you won't be able to breathe out a normal amount of air. Pulse Oximetry For this test, your doctor attaches a small sensor to your finger or ear. The sensor uses light to estimate how much oxygen is in your blood. Arterial Blood Gas Test For this test, your doctor takes a blood sample from an artery, usually in your wrist. The sample is sent to a laboratory, where its oxygen and carbon dioxide levels are measured. This test is more accurate than pulse oximetry. The blood sample also can be tested to see whether an infection is causing your symptoms. Skin Test for Tuberculosis For this test, your doctor injects a substance under the top layer of skin on one of your arms. This substance reacts to tuberculosis (TB). If you have a positive reaction, a small hard lump will develop at the injection site 48 to 72 hours after the test. This test is done to rule out TB. Exercise Testing Exercise testing shows how well your lungs move oxygen and carbon dioxide in and out of your bloodstream when you're active. During this test, you walk or pedal on an exercise machine for a few minutes. An EKG(electrocardiogram) checks your heart rate, a blood pressure cuff checks your blood pressure, and a pulse oximeter shows how much oxygen is in your blood. Your doctor may place a catheter (a flexible tube) in an artery in one of your arms to draw blood samples. These samples will provide a more precise measure of the oxygen and carbon dioxide levels in your blood. Your doctor also may ask you to breathe into a tube that measures oxygen and carbon dioxide levels in your blood. Lung Biopsy For a lung biopsy, your doctor will take samples of lung tissue from several places in your lungs. The samples are examined under a microscope. A lung biopsy is the best way for your doctor to diagnose IPF. This procedure can help your doctor rule out other conditions, such as sarcoidosis (sar-koy-DO-sis), cancer, or infection. Lung biopsy also can show your doctor how far your disease has advanced. Doctors use several procedures to get lung tissue samples. Video-assisted thoracoscopy (thor-ah-KOS-ko-pee). This is the most common procedure used to get lung tissue samples. Your doctor inserts a small tube with an attached light and camera into your chest through small cuts between your ribs. The tube is called an endoscope. The endoscope provides a video image of the lungs and allows your doctor to collect tissue samples. This procedure must be done in a hospital. You'll be given medicine to make you sleep during the procedure. Bronchoscopy (bron-KOS-ko-pee). For a bronchoscopy, your doctor passes a thin, flexible tube through your nose or mouth, down your throat, and into your airways. At the tube's tip are a light and mini-camera. They allow your doctor to see your windpipe and airways. Your doctor then inserts a forceps through the tube to collect tissue samples. You'll be given medicine to help you relax during the procedure. Bronchoalveolar lavage (BRONG-ko-al-VE-o-lar lah-VAHZH). During bronchoscopy, your doctor may inject a small amount of salt water (saline) through the tube into your lungs. This fluid washes the lungs and helps bring up cells from the area around the air sacs. These cells are examined under a microscope. Thoracotomy (thor-ah-KOT-o-me). For this procedure, your doctor removes a few small pieces of lung tissue through a cut in the chest wall between your ribs. Thoracotomy is done in a hospital. You'll be given medicine to make you sleep during the procedure.

### Question: How to diagnose Asbestos-Related Lung Diseases ? ### Response:

Your doctor will diagnose an asbestos-related lung disease based on your past exposure to asbestos, your symptoms, a physical exam, and test results. Specialists Involved Your primary care doctor, such as a family doctor or internist, may provide ongoing care if you have an asbestos-related lung disease. Other specialists also may be involved in your care, including a: Pulmonologist. This is a doctor who specializes in diagnosing and treating lung diseases. Radiologist. This is a doctor who is specially trained to supervise x-ray tests and look at x-ray pictures. Surgeon or oncologist. An oncologist is a doctor who specializes in diagnosing and treating cancer. The surgeon or oncologist may take a tissue sample from your lungs to study under a microscope. Pathologist. A pathologist is a doctor who specializes in identifying diseases by studying cells and tissues under a microscope. A pathologist may study your tissue sample. Exposure to Asbestos Your doctor will want to know about your history of asbestos exposure. He or she may ask about your work history and your spouse's or other family members work histories. Your doctor also may ask about your location and surroundings. For example, he or she may ask about areas of the country where you've lived. If you know you were exposed to asbestos, your doctor may ask questions to find out: How much asbestos you were exposed to. For example, were you surrounded by visible asbestos dust? How long you were exposed to asbestos and how often during that time you were in direct contact with it. Symptoms Your doctor may ask whether you have any symptoms, such as shortness of breath or coughing. The symptoms of asbestos-related lung diseases vary. They depend on which disease you have and how much it has damaged your lungs. Your doctor also may ask whether you smoke. Smoking, along with asbestos exposure, raises your risk for lung cancer. Physical Exam Your doctor will listen to your breathing with a stethoscope to find out whether your lungs are making any strange sounds. If you have a pleural effusion with a lot of fluid buildup, your doctor might hear a dull sound when he or she taps on your chest. Or, he or she might have trouble hearing any breathing sounds. If you have asbestosis, your doctor may hear a crackling sound when you breathe in. Your doctor will check your legs for swelling, which may be a sign of lung-related problems. He or she also will check your fingers and toes for clubbing. Clubbing is the widening and rounding of the fingertips and toes. Clubbing most often is linked to heart and lung diseases that cause lower-than-normal blood oxygen levels. Chest X Ray A chest x ray is the most common test for detecting asbestos-related lung diseases. This painless test creates pictures of the structures inside your chest, such as the lungs. A chest x ray cant detect asbestos fibers in the lungs. However, it can show asbestos-related diseases, such as pleural plaque and pleural effusion. Pleural effusion also can be a sign of a more severe disease, such as mesothelioma. A chest x ray also can show asbestosis. Often the lung tissue will appear very white on the x-ray pictures. The size, shape, location, and degree of whiteness can help your doctor figure out how much lung damage you have. Severe asbestosis may affect the whole lung and have a honeycomb look on the x-ray pictures. If you have lung cancer, a chest x ray may show masses or abnormal fluid. If you have mesothelioma, a chest x ray will show thickening of the pleura. The pleura is the tissue around the lungs and diaphragm (the muscle below your lungs). The chest xray also will usually show signs of pleural effusion in people who have mesothelioma. Other Diagnostic Tests To help confirm a chest x-ray finding, or to find out how much lung damage you have, you may have more tests. Chest Computed Tomography Scan A chest computed tomography (to-MOG-ra-fee) scan, or chest CT scan, is a painless test that creates precise pictures of the structures inside your chest, such as your lungs. A CT scan is a type of x ray, but its pictures show more detail than standard chest x-ray pictures. A chest CT scan may be very helpful for finding asbestosis in its earliest stages, before a standard chest x ray can detect it. Lung Function Tests Lung function tests measure how much air you can breathe in and out, how fast you can breathe air out, and how well your lungs deliver oxygen to your blood. These tests can show whether your lung function is impaired. They also can help your doctor track your disease over time. Biopsy The only way to confirm a diagnosis of lung cancer or mesothelioma is for a pathologist to check samples of your lung cells or tissues. A pathologist is a doctor who identifies diseases by studying cells and tissues under a microscope. Doctors have many ways to collect tissue samples. One way is through bronchoscopy (bron-KOS-ko-pee). For this procedure, your doctor will pass a thin, flexible tube through your nose (or sometimes your mouth), down your throat, and into your airways. He or she will then take a sample of tissue from your lungs. If your doctor thinks you have mesothelioma, you may have a thoracoscopy (thor-ah-KOS-ko-pee). For this procedure, you'll be given medicine so you don't feel any pain. Your doctor will make a small cut through your chest wall. He or she will put a thin tube with a light on it into your chest between two ribs. This allows your doctor to see inside your chest and get tissue samples.

### Question: What are the treatments for Prolactinoma ? ### Response:

The goals of treatment are to return prolactin secretion to normal, reduce tumor size, correct any visual abnormalities, and restore normal pituitary function. In the case of large tumors, only partial achievement of these goals may be possible. Medical Treatment Because dopamine is the chemical that normally inhibits prolactin secretion, doctors may treat prolactinoma with the dopamine agonists bromocriptine (Parlodel) or cabergoline (Dostinex). Agonists are drugs that act like a naturally occurring substance. These drugs shrink the tumor and return prolactin levels to normal in approximately 80 percent of patients. Both drugs have been approved by the U.S. Food and Drug Administration for the treatment of hyperprolactinemia. Bromocriptine is the only dopamine agonist approved for the treatment of infertility. This drug has been in use longer than cabergoline and has a well-established safety record. Nausea and dizziness are possible side effects of bromocriptine. To avoid these side effects, bromocriptine treatment must be started slowly. A typical starting dose is one-quarter to one-half of a 2.5 milligram (mg) tablet taken at bedtime with a snack. The dose is gradually increased every 3 to 7 days as needed and taken in divided doses with meals or at bedtime with a snack. Most people are successfully treated with 7.5 mg a day or less, although some people need 15 mg or more each day. Because bromocriptine is short acting, it should be taken either twice or three times daily. Bromocriptine treatment should not be stopped without consulting a qualified endocrinologist-a doctor specializing in disorders of the hormone-producing glands. Prolactin levels rise again in most people when the drug is discontinued. In some, however, prolactin levels remain normal, so the doctor may suggest reducing or discontinuing treatment every 2 years on a trial basis. Cabergoline is a newer drug that may be more effective than bromocriptine in normalizing prolactin levels and shrinking tumor size. Cabergoline also has less frequent and less severe side effects. Cabergoline is more expensive than bromocriptine and, being newer on the market, its long-term safety record is less well defined. As with bromocriptine therapy, nausea and dizziness are possible side effects but may be avoided if treatment is started slowly. The usual starting dose is .25 mg twice a week. The dose may be increased every 4 weeks as needed, up to 1 mg two times a week. Cabergoline should not be stopped without consulting a qualified endocrinologist. Recent studies suggest prolactin levels are more likely to remain normal after discontinuing long-term cabergoline therapy than after discontinuing bromocriptine. More research is needed to confirm these findings. In people taking cabergoline or bromocriptine to treat Parkinson's disease at doses more than 10 times higher than those used for prolactinomas, heart valve damage has been reported. Rare cases of valve damage have been reported in people taking low doses of cabergoline to treat hyperprolactinemia. Before starting these medications, the doctor will order an echocardiogram. An echocardiogram is a sonogram of the heart that checks the heart valves and heart function. Because limited information exists about the risks of long-term, low-dose cabergoline use, doctors generally prescribe the lowest effective dose and periodically reassess the need for continuing therapy. People taking cabergoline who develop symptoms of shortness of breath or swelling of the feet should promptly notify their physician because these may be signs of heart valve damage. Surgery Surgery to remove all or part of the tumor should only be considered if medical therapy cannot be tolerated or if it fails to reduce prolactin levels, restore normal reproduction and pituitary function, and reduce tumor size. If medical therapy is only partially successful, it should be continued, possibly combined with surgery or radiation. Most often, the tumor is removed through the nasal cavity. Rarely, if the tumor is large or has spread to nearby brain tissue, the surgeon will access the tumor through an opening in the skull. The results of surgery depend a great deal on tumor size and prolactin levels as well as the skill and experience of the neurosurgeon. The higher the prolactin level before surgery, the lower the chance of normalizing serum prolactin. Serum is the portion of the blood used in measuring prolactin levels. In the best medical centers, surgery corrects prolactin levels in about 80 percent of patients with small tumors and a serum prolactin less than 200 nanograms per milliliter (ng/ml). A surgical cure for large tumors is lower, at 30 to 40 percent. Even in patients with large tumors that cannot be completely removed, drug therapy may be able to return serum prolactin to the normal range-20 ng/ml or less-after surgery. Depending on the size of the tumor and how much of it is removed, studies show that 20 to 50 percent will recur, usually within 5 years. Because the results of surgery are so dependent on the skill and knowledge of the neurosurgeon, a patient should ask the surgeon about the number of operations he or she has performed to remove pituitary tumors and for success and complication rates in comparison to major medical centers. The best results come from surgeons who have performed hundreds or even thousands of such operations. To find a surgeon, contact The Pituitary Society (see For More Information). Radiation Rarely, radiation therapy is used if medical therapy and surgery fail to reduce prolactin levels. Depending on the size and location of the tumor, radiation is delivered in low doses over the course of 5 to 6 weeks or in a single high dose. Radiation therapy is effective about 30 percent of the time.

### Question: What is (are) Kidney Failure: Choosing a Treatment That's Right for You ? ### Response:

Purpose of Peritoneal Dialysis The purpose of peritoneal dialysis is to filter wastes and extra fluid from your body. This type of dialysis uses the lining of your bellythe space in your body that holds your stomach, bowels, and liverto filter your blood. This lining, called the peritoneum, acts to do the work of your kidneys. How Peritoneal Dialysis Works A doctor will place a soft tube, called a catheter, in your belly a few weeks before you start treatment. The catheter stays in your belly permanently. When you start peritoneal dialysis, you will empty a kind of salty water, called dialysis solution, from a plastic bag through the catheter into your belly. When the bag is empty, you can disconnect your catheter from the bag so you can move around and do your normal activities. While the dialysis solution is inside your belly, it soaks up wastes and extra fluid from your body. After a few hours, you drain the used dialysis solution through another tube into a drain bag. You can throw away the used dialysis solution, now filled with wastes and extra fluid, in a toilet or tub. Then you start over with a fresh bag of dialysis solution. The process of emptying the used dialysis solution and refilling your belly with fresh solution is called an exchange. The process goes on continuously, so you always have dialysis solution in your belly soaking up wastes and extra fluid from your body. Types of Peritoneal Dialysis Two types of peritoneal dialysis are available. After you have learned about the types of peritoneal dialysis, you can choose the type that best fits your life. If one schedule or type of peritoneal dialysis does not suit you, talk with your doctor about trying the other type. - Continuous ambulatory peritoneal dialysis does not require a machine and you can do it in any clean, well-lit place. The time period that the dialysis solution is in your belly is the dwell time. With continuous ambulatory peritoneal dialysis, the dialysis solution stays in your belly for a dwell time of 4 to 6 hours, or more. The process of draining the used dialysis solution and replacing it with fresh solution takes about 30 to 40 minutes. Most people change the dialysis solution at least four times a day and sleep with solution in their belly at night. With continuous ambulatory peritoneal dialysis, you do not have to wake up and perform dialysis tasks during the night. - Continuous cycler-assisted peritoneal dialysis uses a machine called a cycler to fill and empty your belly three to five times during the night while you sleep. In the morning, you begin one exchange with a dwell time that lasts the entire day. You may do an additional exchange in the middle of the afternoon without the cycler to increase the amount of waste removed and to reduce the amount of fluid left behind in your body. You may need a combination of continuous ambulatory peritoneal dialysis and continuous cycler-assisted peritoneal dialysis if you weigh more than 175 pounds or if your peritoneum filters wastes slowly. For example, some people use a cycler at night and perform one exchange during the day. Others do four exchanges during the day and use a minicycler to perform one or more exchanges during the night. Youll work with your health care team to find the best schedule for you. Pros and Cons of Peritoneal Dialysis Each type of peritoneal dialysis has pros and cons. Continuous Ambulatory Peritoneal Dialysis Pros - You can do continuous ambulatory peritoneal dialysis alone. - You can do continuous ambulatory peritoneal dialysis at the times you choose, as long as you perform the required number of exchanges each day. - You can do continuous ambulatory peritoneal dialysis in many locations. - You can travel as long as you bring dialysis bags with you or have them delivered to your destination. - You dont need a machine for continuous ambulatory peritoneal dialysis. - You gain a sense of control over your treatment. Cons - Continuous ambulatory peritoneal dialysis can disrupt your daily schedule. - Continuous ambulatory peritoneal dialysis is a continuous treatment, and you should do all exchanges 7 days a week. - Boxes of dialysis solution will take up space in your home. Continuous Cycler-assisted Peritoneal Dialysis Pros - You can do exchanges at night, while you sleep. - You may not have to perform exchanges during the day. Cons - You need a machine. - Your connection to the cycler limits your movement at night. Questions to Ask My Doctor - Is peritoneal dialysis the best treatment choice for me? Why? If yes, which type is best? - What type of training do I need, and how long will it take? - What does peritoneal dialysis feel like? - How will peritoneal dialysis affect my ____ [blood pressure, diabetes, other conditions]? - Will I be able to keep working? Will I be able to care for my children? - How much should I exercise? - Where do I store supplies? - How often do I see my doctor? - Who will be on my health care team? How can the members of my health care team help me? - Whom do I contact if I have problems? - With whom can I talk about finances, sex, or family concerns? - How/where can I talk with other people who have faced this decision? More information about Peritoneal Dialysis is provided in the NIDDK health topic, Treatment Methods for Kidney Failure: Peritoneal Dialysis. See also the Kidney Failure Treatment Comparison Chart, which compares peritoneal dialysis, hemodialysis, and transplantation.
