Hepatitis BRead the Hepatitis B article » What is hepatitis?The term 'hepatitis' simply means inflammation of the liver. Hepatitis may be caused by a virus or a toxin such as alcohol. Other viruses that can cause injury to liver cells include the hepatitis A and hepatitis C viruses. These viruses are not related to each other or to hepatitis B virus and differ in their structure, the ways they are spread among individuals, the severity of symptoms they can cause, the way they are treated, and the outcome of the infection. What is the scope of the problem? Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV). It is estimated that 350 million individuals worldwide are infected with the virus, which causes 620,000 deaths worldwide each year. According to the Centers for Disease Control (CDC), approximately 46,000 new cases of hepatitis B occurred in the United States in 2006. In the United States, rates of new infection were highest among people aged 25 to 44 years (3.1 cases per 100,000 population) and lowest among those younger than 15 years of age (0.02 per 100,000). This reflects the major modes of transmission of hepatitis B (sexual transmission, illicit drug use, exposure to infected blood) and the effect of universal vaccination of infants. In the United States, there has been a 75% decrease in newly diagnosed cases of hepatitis B during the past decade. This decrease is attributed to increased vaccination and to heightened public awareness of HIV/AIDS and the resulting safer sexual practices. When a person first gets hepatitis B, they are said to have an 'acute' infection. Most people are able to eliminate the virus and are cured of the infection. Some are not able to clear the virus and have 'chronic' infection with hepatitis B that is usually life-long (see below). In the United States an estimated 800,000 to 1.4 million people are chronically infected with hepatitis B. ...

The goal of a pre-travel medical evaluation is to help travelers protect themselves against (1) common diseases that may be mild but that will disrupt their trip, and (2) less common diseases that may be serious or even fatal. All travelers need to be up to date on routine vaccines they would normally get if they were not traveling. For example, an annual influenza vaccination (flu shot) is recommended if traveling during influenza season. Travelers should also be up to date on te... Emergency Contact for Ontario

Liver
- The liver is the largest solid organ in the body, and is actually an gland. The liver has a wide variety of critical functions such as manufacturing proteins and metabolizing fats and carbohydrates. The liver also eliminates harmful biochemical waste products from the body (alcohol, drugs, toxins). The liver secretes bile that aids in digestion. Examples of diseases of the liver include cirrhosis, hepatitis, cancer, and fatty liver. Symptoms of liver disease include bleeding, easy bruising, edema, fatigue, and jaundice.
-
Cirrhosis (Liver)
- Cirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections. Symptoms include yellowing of the skin, itching, and fatigue.
-
Viral Hepatitis
- Hepatitis is most often viral, due to infection with one of the hepatitis viruses (A, B, C, D, E, F (not confirmed), and G) or another virus (such as those that cause infectious mononucleosis, cytomegalovirus disease). The main nonviral causes of hepatitis are alcohol and drugs. Many patients infected with hepatitis A, B, and C have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu- like symptoms including: loss of appetite, nausea, vomiting, fever, weakness, tiredness, and aching in the abdomen. Treatment of viral hepatitis is dependant on the type of hepatitis.
-
Hepatitis A and B Immunizations
- Hepatitis A and hepatitis B are the two most commnon viruses that infect the liver. Hepatitis A and Hepatitis B can be prevented and treated with immunizations (vaccinations) such as Havrix, Vaqta, Twinrix, Comvax, Pediarix, and hepatitis b immune globulin (HBIG).
-
Pancreatic Cancer
- Pancreatic cancer is a malignant tumor of the pancreas. Pancreatic cancer has been called a "silent" disease because early pancreatic cancer usually does not cause symptoms.
-
Polyarteritis Nodosa
- Polyarteritis nodosa is a rare autoimmune disease characterized by spontaneous inflammation of the arteries of the body. The most common areas of involvement include the muscles, joints, intestines (bowels), nerves, kidneys, and skin. Poor function or pain in any of these organs can be a symptom. Polyarteritis nodosa is most common in middle age persons. Polyarteritis is a serious illness that can be fatal. Treatment is focused on decreasing the inflammation of the arteries by suppressing the immune system.
-
Sexually Transmitted Diseases in Women (STDs)
- Sexually transmitted diseases, or STDs, are infections that are transmitted during any type of sexual exposure, including intercourse (vaginal or anal), oral sex, and the sharing of sexual devices, such as vibrators. Women can contract all of the STDs, but may have no symptoms, or have different symptoms than men do.
-
Travel Medicine
- Travelers should prepare for their trip by visiting their physician to get the proper vaccinations and obtain the necessary medication if they have a medical condition or chronic disease. Diseases that travelers may pick up from contaminated water or food, insect or animal bites, or from other people include malaria, meningococcal meningitis, yellow fever, hepatitis A, typhoid fever, polio, and cholera.
-
Vasculitis
- Vasculitis is a general term for a group of uncommon diseases which feature inflammation of the blood vessels. Each form of vasculitis has its own characteristic pattern of symptoms. The diagnosis of vasculitis is definitively established after a biopsy of involved tissue demonstrates the pattern of blood vessel inflammation. Treatment is directed toward decreasing the inflammation of the arteries and improving the function of affected organs.
-
Hepatitis C
- Hepatitis C is an inflammation of the liver due to the hepatitis C virus (HCV), which is usually spread by blood transfusion, hemodialysis, and needle sticks, especially with intravenous drug abuse. Chronic hepatitis C may be treated with interferon, usually in combination with anti-virals.
-
Jaundice
- Jaundice is a yellowish staining of the skin and whites of the eyes (sclerae) with bilirubin, the pigment found in bile. Jaundice can be an indicator of liver or gallbladder disease, or it may result from the rupture of red blood cells (hemolysis).
-
Fatty Liver
- Nonalcoholic fatty liver disease (NAFLD) refers to a wide spectrum of liver disease ranging from simple fatty liver (steatosis), to nonalcoholic steatohepatitis (NASH), to cirrhosis (irreversible, advanced scarring of the liver). All of the stages of NAFLD have in common the accumulation of fat (fatty infiltration) in the liver cells (hepatocytes).
-
Liver Cancer
- Liver cancer is the fifth most common cancer in the world and the majority of patients with liver cancer will die within one year as a result. Patients with associated cirrhosis caused by chronic hepatitis B or C infections, alcohol, and hemochromatosis are at the greatest risk of developing liver cancer. Many patients with liver cancer do not develop symptoms until the advanced stages of the tumor which usually makes prognosis poor. The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, while a liver biopsy can make a definitive diagnosis. Medical treatments, including chemotherapy, chemoembolization, ablation, and proton beam therapy, are not very effective. Surgical removal of the tumor or a liver transplant may be most effective in certain cases.

There are three types of liver toxicity; dose-dependent toxicity, idiosyncratic toxicity, and drug allergy. The types of liver disease drugs cause include: mild elevations of blood levels of liver enzymes, hepatitis, necrosis, cholestasis, steatosis, cirrhosis, mixed disease, fulminant hepatitis, and blood clots.
-
Steroid Abuse
- Anabolic steroids are synthetic substances that are related to testosterone and promote skeletal muscle growth and the development of male sexual characteristics in both men and women. In the 1930s, it was discovered that anabolic steroids could promote skeletal muscle growth in lab animals, which lead to anabolic steroid abuse by bodybuilders and weight lifters.
