Description
Contents Hepatitis B infection is caused by the Hepatitis B virus and is usually screened for by detecting HBsAg in the blood. Immunity may be discerned by detecting HBsAb, and if absent, the Hepatitis B vaccine or Twinrix® vaccine may be given. - The hepatitis B virus is 100 times more infectious than HIV, the virus that causes AIDS, and infects about 10 times more people than HIV worldwide.
- Hepatitis B virus infects the liver, and more than 350 million people in the world are lifelong hepatitis B virus carriers.
- Long-term hepatitis B virus infection causes at least one million premature deaths every year from cirrhosis of the liver or liver cancer. It is second only to tobacco as the leading cause of cancer in humans.
- Among the Hepatitis B carriers, 25% will develop serious liver diseases, including chronic hepatitis, cirrhosis, and hepatocellular carcinoma.
- The hepatitis B virus can be passed from an infected mother to her baby during childbirth, 1 in 20 Singaporeans are chronically infected with hepatitis B virus.

An improved reverse dot hybridization for simple and rapid detection of adefovir dipivoxil-resistant hepatitis B virus.
Genet Mol Res. 2012;11(1):53-60

Abstract
Early detection of adefovir dipivoxil-resistant mutants during long-term treatment of chronic hepatitis B virus (HBV) infection with this drug is of great clinical importance. We developed an improved reverse dot hybridization test for simple and rapid detection of the rtA181V/T and rtN236T mutations associated with adefovir dipivoxil resistance in chronic hepatitis B patients. Probes were designed for genotypes B, C, and D of this resistance characteristic; a total of 70 clinical samples were analyzed with this improved reverse dot hybridizati...

The CDC's Advisory Committee on Immunization Practices (ACIP) now recommends routine HPV vaccination for males aged 11 to 12 years and catch-up vaccination for males aged 13 to 21. These are just two of the changes to the 2012 Recommended Adult Immunization Schedule published February 1 in Annals of Internal Medicine, the flagship journal of the American College of Physicians (ACP). In addition to the changes in the HPV vaccine, the ACIP now recommends vaccination against Hepatitis B for adults younger than age 60 who have diabetes, as soon as possible after diabetes is diagnosed...

Conclusions:
BM from HCC is rare and associated with an extremely poor prognosis. However, patients with a low RPA class may benefit from aggressive treatment. The clinical implication of extracranial metastases in HCC patients with BM needs further assessment. (Source: BMC Cancer)
