(Medical Xpress)—NC State professor of veterinary internal medicine Ed Breitschwerdt has spent the last couple of decades working with Bartonella, bacteria historically associated with "cat scratch disease." Bartonella is increasingly recognized as a cause of persistent intravascular infection that can result in severe health effects. Research from Breitschwerdt's laboratory and others has led to the discovery of more than 30 new Bartonella species, as well as numerous chronically infected animal "reservoirs" for the bacteria and a variety of insects that can transmit Bartonella to both humans and animals. http://medicalxpress.com/news/2013-04-bartonellosis-stealth-pathogen.html Diseases, Conditions, Syndromes Wed, 24 Apr 2013 06:40:54 EST news286004447 (Medical Xpress)—Medical researchers urge vaccination this flu season as new research shows that hospital-acquired, or nosocomial, influenza is relatively uncommon, but can be severe. http://medicalxpress.com/news/2013-04-hospital-acquired-influenza-rare.html Diseases, Conditions, Syndromes Mon, 15 Apr 2013 06:40:01 EST news285226651 A new national public opinion poll commissioned by Research!America shows only 18% of respondents believe chronic pain is a major health problem, even though a majority of Americans (63%) say they know someone who experienced pain so severe that they sought prescription medicines to treat it.
