Key facts

Hepatitis B is a viral infection that attacks the liver and can cause both acute and chronic disease.
The virus is transmitted through contact with the blood or other body fluids of an infected person - not through casual contact.
About 2 billion people worldwide have been infected with the virus and about 350 million live with chronic infection. An estimated 600 000 persons die each year due to the acute or chronic consequences of hepatitis B.
About 25% of adults who become chronically infected during childhood later die from liver cancer or cirrhosis (scarring of the liver) caused by the chronic infection.
The hepatitis B virus is 50 to 100 times more infectious than HIV.
Hepatitis B virus is an important occupational hazard for health workers.
Hepatitis B is preventable with a safe and effective vaccine.

-----------------------------------
Hepatitis B is a potentially life-threatening liver infection caused by the hepatitis B virus. It is a major global health problem and the most serious type of viral hepatitis. It can cause chronic liver disease and puts people at high risk of death from cirrhosis of the liver and liver cancer.

Worldwide, an estimated two billion people have been infected with the hepatitis B virus (HBV), and more than 350 million have chronic (long-term) liver infections.

A vaccine against hepatitis B has been available since 1982. Hepatitis B vaccine is 95% effective in preventing HBV infection and its chronic consequences, and is the first vaccine against a major human cancer.

Gallbladder cancer is cancer that begins in the gallbladder. Your gallbladder is a small, pear-shaped organ on the right side of your abdomen, just beneath your liver. The gallbladder stores bile, a digestive fluid produced by your liver. Gallbladder cancer is uncommon. When gallbladder cancer is discovered at its earliest stages, the chance for a cure is very good. But most gallbladder cancers are discovered at a late stage, when the prognosis is often very poor. Gallbladder cancer is difficult to diagnose because it often causes no specific signs or symptoms. Also, the relatively hidden nature of the gallbladder makes it easier for gallbladder cancer to grow without being detected.

An abdominal hysterectomy is a surgical procedure that removes your uterus through an incision in your lower abdomen. Your uterus — or womb — is where a baby grows if you're pregnant. A partial hysterectomy removes just the uterus, leaving the cervix intact. A total hysterectomy removes the uterus and the cervix. Sometimes a hysterectomy includes removal of one or both ovaries and fallopian tubes, a procedure called a total hysterectomy with salpingo-oophorectomy (sal-ping-go-o-of-uh-REK-tuh-me). A hysterectomy can also be performed through an incision in the vagina (vaginal hysterectomy) or by a laparoscopic or robotic surgical approach — which uses long, thin instruments passed through small abdominal incisions.

A wart is a skin growth caused by some types of the virus called the human papillomavirus (HPV). HPV infects the top layer of skin, usually entering the body in an area of broken skin. The virus causes the top layer of skin to grow rapidly, forming a wart. Most warts go away on their own within months or years.

Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse. The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone. With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.

nkylosing spondylitis (pronounced ank-kih-low-sing spon-dill-eye-tiss), or AS, is a form of arthritis that primarily affects the spine, although other joints can become involved. It causes inflammation of the spinal joints (vertebrae) that can lead to severe, chronic pain and discomfort
