The genetic underpinnings of panic disorder and manic depressive (bipolar) illness have long eluded scientists.

Researchers Identify Cause Of Diarrheal Illness In Nursing Homes
Gastroenteritis plagues nursing home residents every year, but until recently, scientists have been unable to identify the predominant cause of these outbreaks. Because both bacteria and viruses are potential culprits, researchers decided to investigate how large a role each plays in causing these epidemics. By studying 156 Maryland nursing home residents who became ill over a single winter season, investigators successfully identified a group of Norwalk-like viruses (NLVs) as the leading cause of gastroenteric illness in Maryland nursing homes. Details of the study appear in the Jan. 15 issue of The Journal of Infectious Diseases, which is currently available online. more
