How can patients prevent the spread of vancomycin-resistant enterococci? What should a patient do if they think they have vancomycin-resistant enterococci? Recommendations and Guidelines General Information For more images of this bacterium, search the Public Health Image Library What is vancomycin-resistant enterococci? Enteroccocci are bacteria that are normally present in the human intestines and in the female genital tract and are often found in the environment. These bacteria can sometimes cause infections. Vancomycin is an antibiotic that is used to treat some drug-resistant infections caused by enterococci. In some instances, enterococci have become resistant to this drug and thus are called vancomycin-resistant enterococci (VRE). Most VRE infections occur in hospitals. Top of page What types of infections does VRE cause? VRE can live in the human intestines and female genital tract without causing disease (often called colonization). However, sometimes it can cause infections of the urinary tract, the bloodstream, or of wounds associated with catheters or surgical procedures. Top of page Are certain people at risk of getting VRE? The following persons are at increased risk becoming infected with VRE: People who have been previously treated with the antibiotic vancomycin or other antibiotics for long periods of time. People who are hospitalized, particularly when they receive antibiotic treatment for long periods of time. People with weakened immune systems such as patients in intensive care units, or in cancer or transplant wards. People who have undergone surgical procedures such as abdominal or chest surgery. People with medical devices that stay in for some time such as urinary catheters or central intravenous (IV) catheters. People who are colonized with VRE. Top of page What is the treatment for VRE? People with colonized VRE (bacteria are present, but have no symptoms of an infection) do not need treatment. Most VRE infections can be treated with antibiotics other than vancomycin. Laboratory testing of the VRE can determine which antibiotics will work. For people who get VRE infections in their bladder and have urinary catheters, removal of the catheter when it is no longer needed can also help get rid of the infection. Top of page How is VRE spread? VRE is often passed from person to person by the contaminated hands of caregivers. VRE can get onto a caregiver's hands after they have contact with other people with VRE or after contact with contaminated surfaces. VRE can also be spread directly to people after they touch surfaces that are contaminated with VRE. VRE is not spread through the air by coughing or sneezing. Top of page How can patients prevent the spread of VRE? If a patient or someone in their household has VRE, the following are some things they can do to prevent the spread of VRE: Keep their hands clean. Always wash their hands thoroughly after using the bathroom and before preparing food. Clean their hands after contact with persons who have VRE. Wash with soap and water (particularly when visibly soiled) or use alcohol-based hand rubs. Frequently clean areas of the home, such as bathrooms, that may become contaminated with VRE. Wear gloves if hands may come in contact with body fluids that may contain VRE, such as stool or bandages from infected wounds. Always wash their hands after removing gloves. If someone has VRE, be sure to tell healthcare providers so that they are aware of the infection. Healthcare facilities use special precautions to help prevent the spread of VRE to others. Top of page What should patients do if they think they have vancomycin-resistant enterococci (VRE)? Anyone who thinks they have VRE must talk with their healthcare provider.

Rectal cancer is a disease in which malignant (cancer) cells form in the tissues of the rectum.
The rectum is part of the bodys digestive system. The digestive system takes in nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from foods and helps pass waste material out of the body. The digestive system is made up of the esophagus, stomach, and the small and large intestines. The colon (large bowel) is the first part of the large intestine and is about 5 feet long. Together, the rectum and anal canal make up the last part of the large intestine and are 6-8 inches long. The anal canal ends at the anus (the opening of the large intestine to the outside of the body).

'Cancer of the rectum: Symptoms, causes, diagnosis.'
Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.
Diabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Insulin is made in the pancreas, an organ located behind the stomach. As the blood glucose level rises after a meal, the pancreas is triggered to release insulin. Within the pancreas, clusters of cells called islets contain beta cells, which make the insulin and release it into the blood.
Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. As a result, glucose builds up in the blood instead of being absorbed by cells in the body. The bodys cells are then starved of energy despite high blood glucose levels.
Over time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems.
Main Types of Diabetes
The three main types of diabetes are type 1, type 2, and gestational diabetes:
- Type 1 diabetes, formerly called juvenile diabetes, is usually first diagnosed in children, teenagers, and young adults. In this type of diabetes, the beta cells of the pancreas no longer make insulin because the bodys immune system has attacked and destroyed them. - Type 2 diabetes, formerly called adult-onset diabetes, is the most common type of diabetes. About 90 to 95 percent of people with diabetes have type 2.1 People can develop type 2 diabetes at any age, even during childhood, but this type of diabetes is most often associated with older age. Type 2 diabetes is also associated with excess weight, physical inactivity, family history of diabetes, previous history of gestational diabetes, and certain ethnicities. Type 2 diabetes usually begins with insulin resistance, a condition linked to excess weight in which muscle, liver, and fat cells do not use insulin properly. As a result, the body needs more insulin to help glucose enter cells to be used for energy. At first, the pancreas keeps up with the added demand by producing more insulin. But in time, the pancreas loses its ability to produce enough insulin in response to meals, and blood glucose levels rise. - Gestational diabetes is a type of diabetes that develops only during pregnancy. The hormones produced during pregnancy increase the amount of insulin needed to control blood glucose levels. If the body cant meet this increased need for insulin, women can develop gestational diabetes during the late stages of pregnancy. Gestational diabetes usually goes away after the baby is born. Shortly after pregnancy, 5 to 10 percent of women with gestational diabetes continue to have high blood glucose levels and are diagnosed as having diabetes, usually type 2.1 Research has shown that lifestyle changes and the diabetes medication, metformin, can reduce or delay the risk of type 2 diabetes in these women. Babies born to mothers who had gestational diabetes are also more likely to develop obesity and type 2 diabetes as they grow up. More information about gestational diabetes is provided in the NIDDK health topic, What I need to know about Gestational Diabetes,or by calling 18008608747.
Other Types of Diabetes
Many other types of diabetes exist, and a person can exhibit characteristics of more than one type. For example, in latent autoimmune diabetes in adults, people show signs of both type 1 and type 2 diabetes. Other types of diabetes include those caused by genetic defects, diseases of the pancreas, excess amounts of certain hormones resulting from some medical conditions, medications that reduce insulin action, chemicals that destroy beta cells, infections, rare autoimmune disorders, and genetic syndromes associated with diabetes.

Botulism can result in death due to respiratory failure. However, in the past 50 years the proportion of patients with botulism who die has fallen from about 50% to 3-5%. A patient with severe botulism may require a breathing machine as well as intensive medical and nursing care for several months, and some patients die from infections or other problems related to remaining paralyzed for weeks or months. Patients who survive an episode of botulism poisoning may have fatigue and shortness of breath for years and long-term therapy may be needed to aid recovery.
'What are the tests to diagnose breast cancer?'
Summary : Laboratory tests check a sample of your blood, urine, or body tissues. A technician or your doctor analyzes the test samples to see if your results fall within the normal range. The tests use a range because what is normal differs from person to person. Many factors affect test results. These include - Your sex, age and race - What you eat and drink - Medicines you take - How well you followed pre-test instructions Your doctor may also compare your results to results from previous tests. Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.

'Breast reconstruction after breast cancer.'
Summary : If you need a mastectomy, you have a choice about whether or not to have surgery to rebuild the shape of the breast. Instead of breast reconstruction, you could choose to wear a breast form that replaces the breast, wear padding inside your bra, or do nothing. All of these options have pros and cons. What is right for one woman may not be right for another. Breast reconstruction may be done at the same time as the mastectomy, or it may be done later on. If radiation therapy is part of the treatment plan, your doctor may suggest waiting until after radiation therapy. If you're thinking about breast reconstruction, talk to a plastic surgeon before the mastectomy, even if you plan to have your reconstruction later on. A surgeon can reconstruct the breast in many ways. Some women choose to have breast implants, which are filled with saline or silicone gel. Another method uses tissue taken from another part of your body. The plastic surgeon can take skin, muscle, and fat from your lower abdomen, back, or buttocks. The type of reconstruction that is best for you depends on your age, body type, and the type of cancer surgery that you had. A plastic surgeon can help you decide. NIH: National Cancer Institute
'Breast Cancer'
Key Points
- Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. - Sometimes breast cancer occurs in women who are pregnant or have just given birth. - Signs of breast cancer include a lump or change in the breast. - It may be difficult to detect (find) breast cancer early in pregnant or nursing women. - Breast exams should be part of prenatal and postnatal care. - Tests that examine the breasts are used to detect (find) and diagnose breast cancer. - If cancer is found, tests are done to study the cancer cells. - Certain factors affect prognosis (chance of recovery) and treatment options.
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast.
The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes. Each lobe has many smaller sections called lobules. Lobules end in dozens of tiny bulbs that can make milk. The lobes, lobules, and bulbs are linked by thin tubes called ducts. Each breast also has blood vessels and lymph vessels. The lymph vessels carry an almost colorless fluid called lymph. Lymph vessels carry lymph between lymph nodes. Lymph nodes are small bean-shaped structures that are found throughout the body. They filter substances in lymph and help fight infection and disease. Clusters of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone, and in the chest.
It may be difficult to detect (find) breast cancer early in pregnant or nursing women.
The breasts usually get larger, tender, or lumpy in women who are pregnant, nursing, or have just given birth. This occurs because of normal hormone changes that take place during pregnancy. These changes can make small lumps difficult to detect. The breasts may also become denser. It is more difficult to detect breast cancer in women with dense breasts using mammography. Because these breast changes can delay diagnosis, breast cancer is often found at a later stage in these women.
Other Information About Pregnancy and Breast Cancer
Key Points
- Lactation (breast milk production) and breast-feeding should be stopped if surgery or chemotherapy is planned. - Breast cancer does not appear to harm the unborn baby. - Pregnancy does not seem to affect the survival of women who have had breast cancer in the past.
Lactation (breast milk production) and breast-feeding should be stopped if surgery or chemotherapy is planned.
If surgery is planned, breast-feeding should be stopped to reduce blood flow in the breasts and make them smaller. Breast-feeding should also be stopped if chemotherapy is planned. Many anticancer drugs, especially cyclophosphamide and methotrexate, may occur in high levels in breast milk and may harm the nursing baby. Women receiving chemotherapy should not breast-feed. Stopping lactation does not improve the mother's prognosis.
Breast cancer does not appear to harm the unborn baby.
Breast cancer cells do not seem to pass from the mother to the unborn baby.
Pregnancy does not seem to affect the survival of women who have had breast cancer in the past.
For women who have had breast cancer, pregnancy does not seem to affect their survival. However, some doctors recommend that a woman wait 2 years after treatment for breast cancer before trying to have a baby, so that any early return of the cancer would be detected. This may affect a womans decision to become pregnant. The unborn baby does not seem to be affected if the mother has had breast cancer.
'Who is more prone to breast cancer? Symptoms, stages, and modern treatments.'
Key Points
- After breast cancer has been diagnosed, tests are done to find out if cancer cells have spread within the breast 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 breast cancer: - Stage 0 (carcinoma in situ) - Stage I - Stage II - Stage IIIA - Stage IIIB - Stage IIIC - Stage IV
After breast cancer has been diagnosed, tests are done to find out if cancer cells have spread within the breast or to other parts of the body.
The process used to find out if the cancer has spread within the breast 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. Some procedures may expose the unborn baby to harmful radiation or dyes. These procedures are done only if absolutely necessary. Certain actions can be taken to expose the unborn baby to as little radiation as possible, such as the use of a lead-lined shield to cover the abdomen. The following tests and procedures may be used to stage breast cancer during pregnancy: - 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. - 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. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. - 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 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. - 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, such as the brain. 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, such as the liver, and make echoes. The echoes form a picture of body tissues called a sonogram. The picture can be printed to be looked at later. - 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.
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 breast cancer spreads to the bone, the cancer cells in the bone are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.
The following stages are used for breast cancer:
This section describes the stages of breast cancer. The breast cancer stage is based on the results of testing that is done on the tumor and lymph nodes removed during surgery and other tests. Stage 0 (carcinoma in situ) There are 3 types of breast carcinoma in situ: - Ductal carcinoma in situ (DCIS) is a noninvasive condition in which abnormal cells are found in the lining of a breast duct. The abnormal cells have not spread outside the duct to other tissues in the breast. In some cases, DCIS may become invasive cancer and spread to other tissues. At this time, there is no way to know which lesions could become invasive. - Lobular carcinoma in situ (LCIS) is a condition in which abnormal cells are found in the lobules of the breast. This condition seldom becomes invasive cancer. However, having LCIS in one breast increases the risk of developing breast cancer in either breast. - Paget disease of the nipple is a condition in which abnormal cells are found in the nipple only. Stage I In stage I, cancer has formed. Stage I is divided into stages IA and IB. - In stage IA, the tumor is 2 centimeters or smaller. Cancer has not spread outside the breast. - In stage IB, small clusters of breast cancer cells (larger than 0.2 millimeter but not larger than 2 millimeters) are found in the lymph nodes and either: - no tumor is found in the breast; or - the tumor is 2 centimeters or smaller. Stage II Stage II is divided into stages IIA and IIB. - In stage IIA: - no tumor is found in the breast or the tumor is 2 centimeters or smaller. Cancer (larger than 2 millimeters) is found in 1 to 3 axillary lymph nodes or in the lymph nodes near the breastbone (found during a sentinel lymph node biopsy); or - the tumor is larger than 2 centimeters but not larger than 5 centimeters. Cancer has not spread to the lymph nodes. - In stage IIB, the tumor is: - larger than 2 centimeters but not larger than 5 centimeters. Small clusters of breast cancer cells (larger than 0.2 millimeter but not larger than 2 millimeters) are found in the lymph nodes; or - larger than 2 centimeters but not larger than 5 centimeters. Cancer has spread to 1 to 3 axillary lymph nodes or to the lymph nodes near the breastbone (found during a sentinel lymph node biopsy); or - larger than 5 centimeters. Cancer has not spread to the lymph nodes. Stage IIIA In stage IIIA: - no tumor is found in the breast or the tumor may be any size. Cancer is found in 4 to 9 axillary lymph nodes or in the lymph nodes near the breastbone (found during imaging tests or a physical exam); or - the tumor is larger than 5 centimeters. Small clusters of breast cancer cells (larger than 0.2 millimeter but not larger than 2 millimeters) are found in the lymph nodes; or - the tumor is larger than 5 centimeters. Cancer has spread to 1 to 3 axillary lymph nodes or to the lymph nodes near the breastbone (found during a sentinel lymph node biopsy). Stage IIIB In stage IIIB, the tumor may be any size and cancer has spread to the chest wall and/or to the skin of the breast and caused swelling or an ulcer. Also, cancer may have spread to: - up to 9 axillary lymph nodes; or - the lymph nodes near the breastbone. Cancer that has spread to the skin of the breast may also be inflammatory breast cancer. See the section on Inflammatory Breast Cancer for more information. Stage IIIC In stage IIIC, no tumor is found in the breast or the tumor may be any size. Cancer may have spread to the skin of the breast and caused swelling or an ulcer and/or has spread to the chest wall. Also, cancer has spread to: - 10 or more axillary lymph nodes; or - lymph nodes above or below the collarbone; or - axillary lymph nodes and lymph nodes near the breastbone. Cancer that has spread to the skin of the breast may also be inflammatory breast cancer. See the section on Inflammatory Breast Cancer for more information. For treatment, stage IIIC breast cancer is divided into operable and inoperable stage IIIC. Stage IV In stage IV, cancer has spread to other organs of the body, most often the bones, lungs, liver, or brain.

'Cancer in Family: Is it contagious/transferable? Examining the possibility of cancer transmission within families.'
Diseases Can Have Various Causes Many things influence your overall health and likelihood of developing a disease. Sometimes, it's not clear what causes a disease. Many diseases are thought to be caused by a combination of genetic, lifestyle, and environmental factors. The importance of any particular factor varies from person to person. If you have a disease, does that mean your children and grandchildren will get it, too? Not necessarily. They may have a greater chance of developing the disease than someone without a similar family history. But they are not certain to get the disease. (Watch the video to learn more about why family health history is important. 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.) Health Problems That May Run in Families Common health problems that can run in a family include: - Alzheimer's disease/dementia - arthritis - asthma - blood clots - cancer - depression - diabetes - heart disease - high cholesterol - high blood pressure - pregnancy losses and birth defects - stroke. Alzheimer's disease/dementia arthritis asthma blood clots cancer depression diabetes heart disease high cholesterol high blood pressure pregnancy losses and birth defects stroke. Learn more about the importance of family history in some of these health problems at Diseases, Genetics and Family History. (Center for Disease Control and Prevention) Heritable Diseases Some diseases are clearly heritable. This means the disease comes from a mutation, or harmful change, in a gene inherited from one or both parents. Genes are small structures in your body's cells that determine how you look and tell your body how to work. Examples of heritable diseases are Huntington's disease, cystic fibrosis, and muscular dystrophy. Learn basic information about chromosomes. Learn basic information about DNA. Role of Lifestyle and Environment Genes are not the only things that cause disease. Lifestyle habits and environment also play a major part in developing disease. Diet, weight, physical activity, tobacco and alcohol use, occupation, and where you live can each increase or decrease disease risk. For example, smoking increases the chance of developing heart disease and cancer. For common diseases like heart disease and cancer, habits like smoking or drinking too much alcohol may be more important in causing disease than genes. Sun exposure is the major known environmental factor associated with the development of skin cancer of all types. However, other environmental and genetic factors can also increase a persons risk. The best defense against skin cancer is to encourage sun-protective behaviors, regular skin examinations, and skin self-awareness in an effort to decrease high-risk behaviors and optimize early detection of problems. Learn more about the causes and risk factors for skin cancer. Clues to Your Disease Risk Creating a family health history helps you know about diseases and disease risks. It can also show the way a disease occurs in a family. For example, you may find that a family member had a certain disease at an earlier age than usual (10 to 20 years before most people get it). That can increase other family members' risk. Risk also goes up if a relative has a disease that usually does not affect a certain gender, for example, breast cancer in a man. Certain combinations of diseases within a family -- such as breast and ovarian cancer, or heart disease and diabetes -- also increase the chance of developing those diseases. Some Risk Factors Are Not Apparent Even if they appear healthy, people could be at risk for developing a serious disease that runs in the family. They could have risk factors that they cannot feel, such as high blood pressure. They might not even know the disease runs in their family because they've lost touch with family members with the disease or because other family members with the disease have kept the information private. Another possibility is that family members who might have developed the disease died young in accidents or by other means. They might also be adopted and not share genes with members of their adoptive family. Getting Professional Advice Family members who think they might be at risk for a disease based on their family health history can ask their health care professionals for advice. The professional may order a test to see if the person has the disease or a risk factor for the disease. For instance, a mammogram can detect possible breast cancer, and a colonoscopy can find colon cancer. Many diseases are more treatable if they are caught early. The first step toward better understanding of your family's health is to learn more about the health of close relatives such as parents, brothers and sisters, and children. Creating a family health history is one way to do that.

On this Page General Information about VISA/VRSA What is Staphylococcus aureus? How do VISA and VRSA get their names? What should a patient do if they suspect they have a Staph, MRSA, VISA, or VRSA infection? Are VISA and VRSA infections treatable? How can the spread of VISA and VRSA be prevented? What should a person do if a family member or close friend has VISA or VRSA? What is CDC doing to address VISA and VRSA? Recommendations and Guidelines General Information about VISA/VRSA For more images of this bacterium, search the Public Health Image Library Vancomycin [van−kō−mī−sin]-intermediate Staphylococcus aureus [staff−u−lu−kaw−kus aw−ree−us] (also called VISA) and Vancomycin-resistant Staphylococcus aureus (also called VRSA) are specific types of antimicrobial-resistant bacteria. However, as of October 2010, all VISA and VRSA isolates have been susceptible to other Food and Drug Administration (FDA)-approved drugs. Persons who develop this type of staph infection may have underlying health conditions (such as diabetes and kidney disease), tubes going into their bodies (such as catheters), previous infections with methicillin-resistant Staphylococcus aureus (MRSA), and recent exposure to vancomycin and other antimicrobial agents. What is Staphylococcus aureus? Staphylococcus aureus is a bacterium commonly found on the skin and in the nose of about 30% of individuals. Most of the time, staph does not cause any harm. These infections can look like pimples, boils, or other skin conditions and most are able to be treated. Sometimes staph bacteria can get into the bloodstream and cause serious infections which can be fatal, including: Bacteremia or sepsis when bacteria spread to the bloodstream usually as a result of using catheters or having surgery. Pneumonia which predominantly affects people with underlying lung disease including those on mechanical ventilators. Endocarditis (infection of the heart valves) which can lead to heart failure. Osteomyelitis (bone infection) which can be caused by staph bacteria traveling in the bloodstream or put there by direct contact such as following trauma (puncture wound of foot or intravenous (IV) drug abuse). Top of page How do VISA and VRSA get their names? Staph bacteria are classified as VISA or VRSA based on laboratory tests. Laboratories perform tests to determine if staph bacteria are resistant to antimicrobial agents that might be used for treatment of infections. For vancomycin and other antimicrobial agents, laboratories determine how much of the agent it requires to inhibit the growth of the organism in a test tube. The result of the test is usually expressed as a minimum inhibitory concentration (MIC) or the minimum amount of antimicrobial agent that inhibits bacterial growth in the test tube. Therefore, staph bacteria are classified as VISA if the MIC for vancomycin is 4-8µg/ml, and classified as VRSA if the vancomycin MIC is ≥16µg/ml. Top of page What should a patient do if they suspect they have a staph, MRSA, VISA, or VRSA infection? See a healthcare provider. Top of page Are VISA and VRSA infections treatable? Yes. As of October 2010, all VISA and VRSA isolates have been susceptible to several Food and Drug Administration (FDA)-approved drugs. Top of page How can the spread of VISA and VRSA be prevented? Use of appropriate infection control practices (such as wearing gloves before and after contact with infectious body substances and adherence to hand hygiene) by healthcare personnel can reduce the spread of VISA and VRSA. Top of page What should a person do if a family member or close friend has VISA or VRSA? VISA and VRSA are types of antibiotic-resistant staph bacteria. Therefore, as with all staph bacteria, spread occurs among people having close physical contact with infected patients or contaminated material, such as bandages. Persons having close physical contact with infected patients while they are outside of the healthcare setting should: (1) keep their hands clean by washing thoroughly with soap and water, and (2) avoid contact with other people's wounds or material contaminated from wounds. If they go to the hospital to visit a friend or family member who is infected with VISA or VRSA , they must follow the hospital's recommended precautions. Top of page What is CDC doing to address VISA and VRSA? In addition to providing guidance for clinicians and infection control personnel, CDC is also working with state and local health agencies, healthcare facilities, and clinical microbiology laboratories to ensure that laboratories are using proper methods to detect VISA and VRSA. Top of page Recommendations and Guidelines CDC issued a Clinical Reminder, in 2010, which serves as a reminder about the important role of clinical laboratories in the diagnosis of VRSA cases to ensure prompt recognition, isolation, and management by infection control personnel. Investigation and Control of Vancomycin-Resistant Staphylococcus aureus (VRSA) [PDF - 300 KB] - This document is a guide to conducting a public health investigation of patients from whom vancomycin-resistant Staphylococcus aureus (VRSA, vancomycin MIC ≥ 16 µg/ml) has been isolated.

Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.
Diabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Insulin is made in the pancreas, an organ located behind the stomach. As the blood glucose level rises after a meal, the pancreas is triggered to release insulin. Within the pancreas, clusters of cells called islets contain beta cells, which make the insulin and release it into the blood.
Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. As a result, glucose builds up in the blood instead of being absorbed by cells in the body. The bodys cells are then starved of energy despite high blood glucose levels.
Over time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems.
Main Types of Diabetes
The three main types of diabetes are type 1, type 2, and gestational diabetes:
- Type 1 diabetes, formerly called juvenile diabetes, is usually first diagnosed in children, teenagers, and young adults. In this type of diabetes, the beta cells of the pancreas no longer make insulin because the bodys immune system has attacked and destroyed them. - Type 2 diabetes, formerly called adult-onset diabetes, is the most common type of diabetes. About 90 to 95 percent of people with diabetes have type 2.1 People can develop type 2 diabetes at any age, even during childhood, but this type of diabetes is most often associated with older age. Type 2 diabetes is also associated with excess weight, physical inactivity, family history of diabetes, previous history of gestational diabetes, and certain ethnicities. Type 2 diabetes usually begins with insulin resistance, a condition linked to excess weight in which muscle, liver, and fat cells do not use insulin properly. As a result, the body needs more insulin to help glucose enter cells to be used for energy. At first, the pancreas keeps up with the added demand by producing more insulin. But in time, the pancreas loses its ability to produce enough insulin in response to meals, and blood glucose levels rise. - Gestational diabetes is a type of diabetes that develops only during pregnancy. The hormones produced during pregnancy increase the amount of insulin needed to control blood glucose levels. If the body cant meet this increased need for insulin, women can develop gestational diabetes during the late stages of pregnancy. Gestational diabetes usually goes away after the baby is born. Shortly after pregnancy, 5 to 10 percent of women with gestational diabetes continue to have high blood glucose levels and are diagnosed as having diabetes, usually type 2.1 Research has shown that lifestyle changes and the diabetes medication, metformin, can reduce or delay the risk of type 2 diabetes in these women. Babies born to mothers who had gestational diabetes are also more likely to develop obesity and type 2 diabetes as they grow up. More information about gestational diabetes is provided in the NIDDK health topic, What I need to know about Gestational Diabetes,or by calling 18008608747.
Other Types of Diabetes
Many other types of diabetes exist, and a person can exhibit characteristics of more than one type. For example, in latent autoimmune diabetes in adults, people show signs of both type 1 and type 2 diabetes. Other types of diabetes include those caused by genetic defects, diseases of the pancreas, excess amounts of certain hormones resulting from some medical conditions, medications that reduce insulin action, chemicals that destroy beta cells, infections, rare autoimmune disorders, and genetic syndromes associated with diabetes.

Recommendations and Guidelines General Information For more images of this bacterium, search the Public Health Image Library What is vancomycin-resistant enterococci? Enteroccocci are bacteria that are normally present in the human intestines and in the female genital tract and are often found in the environment. These bacteria can sometimes cause infections. Vancomycin is an antibiotic that is used to treat some drug-resistant infections caused by enterococci. In some instances, enterococci have become resistant to this drug and thus are called vancomycin-resistant enterococci (VRE). Most VRE infections occur in hospitals. Top of page What types of infections does VRE cause? VRE can live in the human intestines and female genital tract without causing disease (often called colonization). However, sometimes it can cause infections of the urinary tract, the bloodstream, or of wounds associated with catheters or surgical procedures. Top of page Are certain people at risk of getting VRE? The following persons are at increased risk becoming infected with VRE: People who have been previously treated with the antibiotic vancomycin or other antibiotics for long periods of time. People who are hospitalized, particularly when they receive antibiotic treatment for long periods of time. People with weakened immune systems such as patients in intensive care units, or in cancer or transplant wards. People who have undergone surgical procedures such as abdominal or chest surgery. People with medical devices that stay in for some time such as urinary catheters or central intravenous (IV) catheters. People who are colonized with VRE. Top of page What is the treatment for VRE? People with colonized VRE (bacteria are present, but have no symptoms of an infection) do not need treatment. Most VRE infections can be treated with antibiotics other than vancomycin. Laboratory testing of the VRE can determine which antibiotics will work. For people who get VRE infections in their bladder and have urinary catheters, removal of the catheter when it is no longer needed can also help get rid of the infection. Top of page How is VRE spread? VRE is often passed from person to person by the contaminated hands of caregivers. VRE can get onto a caregiver's hands after they have contact with other people with VRE or after contact with contaminated surfaces. VRE can also be spread directly to people after they touch surfaces that are contaminated with VRE. VRE is not spread through the air by coughing or sneezing. Top of page How can patients prevent the spread of VRE? If a patient or someone in their household has VRE, the following are some things they can do to prevent the spread of VRE: Keep their hands clean. Always wash their hands thoroughly after using the bathroom and before preparing food. Clean their hands after contact with persons who have VRE. Wash with soap and water (particularly when visibly soiled) or use alcohol-based hand rubs. Frequently clean areas of the home, such as bathrooms, that may become contaminated with VRE. Wear gloves if hands may come in contact with body fluids that may contain VRE, such as stool or bandages from infected wounds. Always wash their hands after removing gloves. If someone has VRE, be sure to tell healthcare providers so that they are aware of the infection. Healthcare facilities use special precautions to help prevent the spread of VRE to others. Top of page What should patients do if they think they have vancomycin-resistant enterococci (VRE)? Anyone who thinks they have VRE must talk with their healthcare provider.

High Blood Cholesterol and Triglyceride Levels
Cholesterol
High blood cholesterol is a condition in which your blood has too much cholesterola waxy, fat-like substance. The higher your blood cholesterol level, the greater your risk of coronary heart disease (CHD) and heart attack.
Cholesterol travels through the bloodstream in small packages called lipoproteins. Two major kinds of lipoproteins carry cholesterol throughout your body:
Low-density lipoproteins (LDL). LDL cholesterol sometimes is called "bad" cholesterol. This is because it carries cholesterol to tissues, including your heart arteries. A high LDL cholesterol level raises your risk of CHD.
High-density lipoproteins (HDL). HDL cholesterol sometimes is called "good" cholesterol. This is because it helps remove cholesterol from your arteries. A low HDL cholesterol level raises your risk of CHD.
Many factors affect your cholesterol levels. For example, after menopause, women's LDL cholesterol levels tend to rise, and their HDL cholesterol levels tend to fall. Other factorssuch as age, gender, diet, and physical activityalso affect your cholesterol levels.
Healthy levels of both LDL and HDL cholesterol will prevent plaque from building up in your arteries. Routine blood tests can show whether your blood cholesterol levels are healthy. Talk with your doctor about having your cholesterol tested and what the results mean.
Children also can have unhealthy cholesterol levels, especially if they're overweight or their parents have high blood cholesterol. Talk with your child's doctor about testing your child' cholesterol levels.
To learn more about high blood cholesterol and how to manage the condition, go to the Health Topics High Blood Cholesterol article.
Triglycerides
Triglycerides are a type of fat found in the blood. Some studies suggest that a high level of triglycerides in the blood may raise the risk of CHD, especially in women.
High Blood Pressure
"Blood pressure" is the force of blood pushing against the walls of your arteries as your heart pumps blood. If this pressure rises and stays high over time, it can damage your heart and lead to plaque buildup.All levels above 120/80 mmHg raise your risk of CHD. This risk grows as blood pressure levels rise. Only one of the two blood pressure numbers has to be above normal to put you at greater risk of CHD and heart attack.
Most adults should have their blood pressure checked at least once a year. If you have high blood pressure, you'll likely need to be checked more often. Talk with your doctor about how often you should have your blood pressure checked.
Children also can develop high blood pressure, especially if they're overweight. Your child's doctor should check your child's blood pressure at each routine checkup.
Both children and adults are more likely to develop high blood pressure if they're overweight or have diabetes.
For more information about high blood pressure and how to manage the condition, go to the Health Topics High Blood Pressure article.
Diabetes and Prediabetes
Diabetes is a disease in which the body's blood sugar level is too high. The two types of diabetes are type 1 and type 2.
In type 1 diabetes, the body's blood sugar level is high because the body doesn't make enough insulin. Insulin is a hormone that helps move blood sugar into cells, where it's used for energy. In type 2 diabetes, the body's blood sugar level is high mainly because the body doesn't use its insulin properly.
Over time, a high blood sugar level can lead to increased plaque buildup in your arteries. Having diabetes doubles your risk of CHD.
Prediabetes is a condition in which your blood sugar level is higher than normal, but not as high as it is in diabetes. If you have prediabetes and don't take steps to manage it, you'll likely develop type 2 diabetes within 10 years. You're also at higher risk of CHD.
Being overweight or obese raises your risk of type 2 diabetes. With modest weight loss and moderate physical activity, people who have prediabetes may be able to delay or prevent type 2 diabetes. They also may be able to lower their risk of CHD and heart attack. Weight loss and physical activity also can help control diabetes.
Even children can develop type 2 diabetes. Most children who have type 2 diabetes are overweight.
Type 2 diabetes develops over time and sometimes has no symptoms. Go to your doctor or local clinic to have your blood sugar levels tested regularly to check for diabetes and prediabetes.
For more information about diabetes and heart disease, go to the Health Topics Diabetic Heart Disease article. For more information about diabetes and prediabetes, go to the National Institute of Diabetes and Digestive and Kidney Diseases' (NIDDK's) Introduction to Diabetes.
Overweight and Obesity
The terms "overweight" and "obesity" refer to body weight that's greater than what is considered healthy for a certain height. More than two-thirds of American adults are overweight, and almost one-third of these adults are obese.
The most useful measure of overweight and obesity is body mass index (BMI).You can use the National Heart, Lung, and Blood Institute's (NHLBI's) online BMI calculator to figure out your BMI, or your doctor can help you.
Overweight is defined differently for children and teens than it is for adults. Children are still growing, and boys and girls mature at different rates. Thus, BMIs for children and teens compare their heights and weights against growth charts that take age and gender into account. This is called BMI-for-age percentile.
Being overweight or obese can raise your risk of CHD and heart attack. This is mainly because overweight and obesity are linked to other CHD risk factors, such as high blood cholesterol and triglyceride levels, high blood pressure, and diabetes.
For more information, go to the Health Topics Overweight and Obesity article.
Smoking
Smoking tobacco or long-term exposure to secondhand smoke raises your risk of CHD and heart attack.
Smoking triggers a buildup of plaque in your arteries. Smoking also increases the risk of blood clots forming in your arteries. Blood clots can block plaque-narrowed arteries and cause a heart attack.Some research shows that smoking raises your risk of CHD in part by lowering HDL cholesterol levels.
The more you smoke, the greater your risk of heart attack. The benefits of quitting smoking occur no matter how long or how much you've smoked. Heart disease risk associated with smoking begins to decrease soon after you quit, and for many people it continues to decrease over time.
Most people who smoke start when they're teens. Parents can help prevent their children from smoking by not smoking themselves. Talk with your child about the health dangers of smoking and ways to overcome peer pressure to smoke.
For more information, including tips on how to quit smoking, go to the Health Topics Smoking and Your Heart article and the NHLBI's "Your Guide to a Healthy Heart."

Inactive people are nearly twice as likely to develop CHD as those who are active. A lack of physical activity can worsen other CHD risk factors, such as high blood cholesterol and triglyceride levels, high blood pressure, diabetes and prediabetes, and overweight and obesity.
It's important for children and adults to make physical activity part of their daily routines. One reason many Americans aren't active enough is because of hours spent in front of TVs and computers doing work, schoolwork, and leisure activities.
Some experts advise that children and teens should reduce screen time because it limits time for physical activity. They recommend that children aged 2 and older should spend no more than 2 hours a day watching TV or using a computer (except for school work).
Being physically active is one of the most important things you can do to keep your heart healthy. The good news is that even modest amounts of physical activity are good for your health. The more active you are, the more you will benefit.
For more information, go to HHS' "2008 Physical Activity Guidelines for Americans," the Health Topics Physical Activity and Your Heart article, and the NHLBI's "Your Guide to Physical Activity and Your Heart."
Unhealthy Diet
An unhealthy diet can raise your risk of CHD. For example, foods that are high in saturated and trans fats and cholesterol raise LDL cholesterol. Thus, you should try to limit these foods.
It's also important to limit foods that are high in sodium (salt) and added sugars. A high-salt diet can raise your risk of high blood pressure.
Added sugars will give you extra calories without nutrients like vitamins and minerals. This can cause you to gain weight, which raises your risk of CHD. Added sugars are found in many desserts, canned fruits packed in syrup, fruit drinks, and nondiet sodas.
Stress
Stress and anxiety may play a role in causing CHD. Stress and anxiety also can trigger your arteries to tighten. This can raise your blood pressure and your risk of heart attack.
The most commonly reported trigger for a heart attack is an emotionally upsetting event, especially one involving anger. Stress also may indirectly raise your risk of CHD if it makes you more likely to smoke or overeat foods high in fat and sugar.
Age
In men, the risk for coronary heart disease (CHD) increases starting around age 45. In women, the risk for CHD increases starting around age 55. Most people have some plaque buildup in their heart arteries by the time theyre in their 70s. However, only about 25 percent of those people have chest pain, heart attacks, or other signs of CHD.
Gender
Some risk factors may affect CHD risk differently in women than in men. For example, estrogen provides women some protection against CHD, whereas diabetes raises the risk of CHD more in women than in men.
Also, some risk factors for heart disease only affect women, such as preeclampsia, a condition that can develop during pregnancy. Preeclampsia is linked to an increased lifetime risk of heart disease, including CHD, heart attack, heart failure, and high blood pressure. (Likewise, having heart disease risk factors, such as diabetes or obesity, increases a womans risk of preeclampsia.)
Family History
A family history of early CHD is a risk factor for developing CHD, specifically if a father or brother is diagnosed before age 55, or a mother or sister is diagnosed before age 65.
'Liver cancer: Signs, symptoms, and treatment.'
The first symptoms of rabies may be very similar to those of the flu including general weakness or discomfort, fever, or headache. These symptoms may last for days.
There may be also discomfort or a prickling or itching sensation at the site of bite, progressing within days to symptoms of cerebral dysfunction, anxiety, confusion, agitation. As the disease progresses, the person may experience delirium, abnormal behavior, hallucinations, and insomnia.
The acute period of disease typically ends after 2 to 10 days. Once clinical signs of rabies appear, the disease is nearly always fatal, and treatment is typically supportive.
Disease prevention includes administration of both passive antibody, through an injection of human immune globulin and a round of injections with rabies vaccine.
Once a person begins to exhibit signs of the disease, survival is rare. To date less than 10 documented cases of human survival from clinical rabies have been reported and only two have not had a history of pre- or postexposure prophylaxis.
'Cervical cancer: Prevention and treatment.'
Heart disease is the leading cause of death in the U.S. It is also a major cause of disability. The risk of heart disease increases as you age. You have a greater risk of heart disease if you are a man over age 45 or a woman over age 55. You also are at greater risk if you have a close family member who had heart disease at an early age. Fortunately, there are many things you can do reduce your chances of getting heart disease. You should - Know your blood pressure and keep it under control - Exercise regularly - Don't smoke - Get tested for diabetes and if you have it, keep it under control - Know your cholesterol and triglyceride levels and keep them under control - Eat a lot of fruits and vegetables - Maintain a healthy weight
'Breast cancer'
Key Points
- Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. - Sometimes breast cancer occurs in women who are pregnant or have just given birth. - Signs of breast cancer include a lump or change in the breast. - It may be difficult to detect (find) breast cancer early in pregnant or nursing women. - Breast exams should be part of prenatal and postnatal care. - Tests that examine the breasts are used to detect (find) and diagnose breast cancer. - If cancer is found, tests are done to study the cancer cells. - Certain factors affect prognosis (chance of recovery) and treatment options.
Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast.
The breast is made up of lobes and ducts. Each breast has 15 to 20 sections called lobes. Each lobe has many smaller sections called lobules. Lobules end in dozens of tiny bulbs that can make milk. The lobes, lobules, and bulbs are linked by thin tubes called ducts. Each breast also has blood vessels and lymph vessels. The lymph vessels carry an almost colorless fluid called lymph. Lymph vessels carry lymph between lymph nodes. Lymph nodes are small bean-shaped structures that are found throughout the body. They filter substances in lymph and help fight infection and disease. Clusters of lymph nodes are found near the breast in the axilla (under the arm), above the collarbone, and in the chest.
It may be difficult to detect (find) breast cancer early in pregnant or nursing women.
The breasts usually get larger, tender, or lumpy in women who are pregnant, nursing, or have just given birth. This occurs because of normal hormone changes that take place during pregnancy. These changes can make small lumps difficult to detect. The breasts may also become denser. It is more difficult to detect breast cancer in women with dense breasts using mammography. Because these breast changes can delay diagnosis, breast cancer is often found at a later stage in these women.
Other Information About Pregnancy and Breast Cancer
Key Points
- Lactation (breast milk production) and breast-feeding should be stopped if surgery or chemotherapy is planned. - Breast cancer does not appear to harm the unborn baby. - Pregnancy does not seem to affect the survival of women who have had breast cancer in the past.
Lactation (breast milk production) and breast-feeding should be stopped if surgery or chemotherapy is planned.
If surgery is planned, breast-feeding should be stopped to reduce blood flow in the breasts and make them smaller. Breast-feeding should also be stopped if chemotherapy is planned. Many anticancer drugs, especially cyclophosphamide and methotrexate, may occur in high levels in breast milk and may harm the nursing baby. Women receiving chemotherapy should not breast-feed. Stopping lactation does not improve the mother's prognosis.
Breast cancer does not appear to harm the unborn baby.
Breast cancer cells do not seem to pass from the mother to the unborn baby.
Pregnancy does not seem to affect the survival of women who have had breast cancer in the past.
For women who have had breast cancer, pregnancy does not seem to affect their survival. However, some doctors recommend that a woman wait 2 years after treatment for breast cancer before trying to have a baby, so that any early return of the cancer would be detected. This may affect a womans decision to become pregnant. The unborn baby does not seem to be affected if the mother has had breast cancer.
'Symptoms of lung cancer.'
Signs and symptoms of small cell lung cancer include coughing, shortness of breath, and chest pain. These and other signs and symptoms may be caused by small cell lung cancer or by other conditions. Check with your doctor if you have any of the following: - Chest discomfort or pain. - A cough that doesnt go away or gets worse over time. - Trouble breathing. - Wheezing. - Blood in sputum (mucus coughed up from the lungs). - Hoarseness. - Trouble swallowing. - Loss of appetite. - Weight loss for no known reason. - Feeling very tired. - Swelling in the face and/or veins in the neck.
