(AP) -- The number of people worldwide infected with the virus that causes AIDS - about 33 million - has remained virtually unchanged for the last two years, United Nations experts said Tuesday. http://www.physorg.com/news178269287.html Medicine & Health Tue, 24 Nov 2009 07:15:34 EST news178269287 (AP) -- Malaria. Tuberculosis. Alzheimer's disease. AIDS. Pandemic flu. Genital herpes. Urinary tract infections. Grass allergies. Traveler's diarrhea. You name it, the pharmaceutical industry is working on a vaccine to prevent it. http://www.physorg.com/news177690830.html Medicine & Health Tue, 17 Nov 2009 14:34:41 EST news177690830 Despite evidence that low-cost diarrhea treatments such as lower osmolarity oral rehydration salts (ORS) and zinc supplements could drastically reduce the number of deaths among children, little progress has been made in implementing these life-saving techniques, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They examined the implementation of current treatment guidelines and found that few countries are equipped to quickly adapt policies, and many struggle to develop and maintain the recommended supplies. The analysis is featured in the October issue of Bulletin of the World Health Organization. http://www.physorg.com/news174244874.html Medicine & Health Thu, 08 Oct 2009 18:21:29 EST news174244874 New research indicates that patients with lesser degrees of celiac disease-related symptoms, such as intestinal inflammation or latent celiac disease, have a modestly increased risk of death, according to a study in the September 16 issue of JAMA. http://www.physorg.com/news172253396.html Medicine & Health Tue, 15 Sep 2009 18:10:03 EST news172253396 As public health experts warn of potential widespread outbreaks of H1N1 flu this school year, a new study from North Carolina State University shows that students do not comply with basic preventative measures as much as they think do.

This condition is characterized by chronic watery diarrhea and abnormal deposition of collagen beneath the colonic epithelium. Severe hypoproteinemia due to enteric protein loss is rare unless accompanied by small bowel malabsorption syndrome. To the best of authors' knowledge, only 1 case of collagenous colitis associated with protein-losing enteropathy (PLE) in the absence of small bowel disease has been reported. http://www.physorg.com/news144925891.html Medicine & Health Mon, 03 Nov 2008 09:11:31 EST news144925891 The research team led by Levent Erdem from Şişli Etfal Teaching and Research Hospital of Turkey investigated the prevalence and demography of microscopic colitis in patients with diarrhea of unknown etiology and normal colonoscopy in Turkey.
