What Is Narcolepsy? What Causes Narcolepsy?
Narcolepsy - from the French narcolepsie, which was derived from the Greek narke meaning numbness and lepsis meaning attack or seizure - is a chronic sleep disorder where the brain is unable to regulate the body"s sleep-wake cycles.

Report Estimates Significant Impact Of Widespread Circumcision Effort In Botswana

Botswana"s campaign to circumcise about 500,000 men by 2012 will prevent nearly 70,000 new HIV cases by 2025, according to a report published Thursday in the Journal of the International AIDS Society, AFP/Yahoo! News reports. The government"s national campaign aims to circumcise 460,000 men over the next five years, and the country has begun airing television and radio advertisements to encourage men to be circumcised at local clinics. "Scaling up safe male circumcision has the potential to reduce the impact of HIV/AIDS in Botswana significantly," according to the study. The report puts the estimated cost of the circumcision campaign at about $47 million. A UNAIDS report estimates that the HIV prevalence among pregnant women in Botswana was 43% in 2003, the year that antiretroviral drug access was introduced in the country (AFP/Yahoo! News, 5/28). An abstract of the study is available online. Reprinted with kind permission from http://www.kaisernetwork.org.
