Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells. Two new studies advance that argument and demonstrate how shielding lung cancer cells from opiates reduces cell proliferation, invasion and migration in both cell-culture and mouse models. http://www.physorg.com/news177772193.html Medicine & Health Wed, 18 Nov 2009 13:10:49 EST news177772193 Despite a national focus on reducing surgical errors, surgery-related adverse events continue to occur both inside and outside the operating room, according to an analysis of events at Veterans Health Administration Medical Centers published in the November issue of Archives of Surgery. http://www.physorg.com/news177620441.html Medicine & Health Mon, 16 Nov 2009 20:00:01 EST news177620441 New research published in the November issue of the Journal of the American College of Surgeons shows that African-American patients with colorectal cancer are more likely to be diagnosed with advanced disease and are less likely to undergo surgical procedures compared with Caucasians, suggesting that improvements in screening and rates of operation may reduce differences in colorectal cancer outcomes for African-Americans. http://www.physorg.com/news177248427.html Medicine & Health Thu, 12 Nov 2009 12:10:04 EST news177248427 Three leading scientific organizations specializing in infectious diseases prevention issued a letter to President Obama today expressing their significant concern with current federal guidance concerning the use of personal protective equipment (PPE) by healthcare workers in treating suspected or confirmed cases of 2009 H1N1 influenza. http://www.physorg.com/news176750023.html Medicine & Health Fri, 06 Nov 2009 17:50:02 EST news176750023 At the end of a 10-year, coast-to-coast study of women with an unusual form of breast cancer, Richard J.
