Since 1996, there has been a flurry of scientific activity to evaluate the possibility that cellular telephone use may cause brain tumors, reflecting the rapid increase in the use of these phones throughout the world. Overall, the epidemiologic and laboratory studies to date have ruled out with a reasonable degree of certainty that cellular telephones cause cancer, at least for durations of use up to 5 years. RF signals from cellular telephones are not genotoxic and cannot directly damage DNA, and are thus unlikely to be in itiators; hence the risk of cancer from a thermal or non-thermal mechanism would be one that, if anything, promotes tumor growth.

Risk management of HBsAg or anti-HCV positive healthcare workers in hospital.

Recommendations are made for controlling the transmission of the hepatitis B and hepatitis C viruses from healthcare workers to patients. These recommendations were based both on the literature and on experts' opinions, obtained during a Consensus Conference. The quality of the published information and of the experts' opinions was classified into 6 levels, based on the source of the information.
