What Snake Caused That Bite? New DNA Test Might Tell

Posted: Published on November 5th, 2014

Latest Prevention & Wellness News TUESDAY, Nov. 4, 2014 (HealthDay News) -- DNA tests can reliably identify the type of snake that has bitten a person and could save the lives of many people in countries with deadly venomous snakes, new research reports. Experts found that if snake DNA could be detected on swabs taken from fang marks on victims, the species of snake could be pinpointed every time. The study was scheduled to be presented Tuesday at the annual meeting of the American Society of Tropical Medicine and Hygiene in New Orleans. "These findings represent a significant step toward improving care for patients in areas of the world where snakebites constitute a massive but neglected health risk," study director Dr. Francois Chappuis, chief of the division of tropical and humanitarian medicine at Geneva University Hospitals in Switzerland, said in a society news release. "This DNA test may hasten more effective bedside diagnostics for snakebite victims, giving them a better chance of surviving and making a full recovery," Chappuis added. The researchers studied snakebite victims in Nepal and found that snake DNA could be obtained from about one in four of the bite wounds. One reason why DNA could not … Continue reading

Forensic DNA test conclusively links snake bite marks on people to species

Posted: Published on November 5th, 2014

Starting with a simple DNA swab taken from fang marks on people bitten by snakes, an international research team correctly identified the species of the biting snake 100 percent of the time in a first-of-its-kind clinical study, according to data presented today at the American Society of Tropical Medicine and Hygiene's (ASTMH) Annual Meeting. The study, conducted at three medical facilities in Nepal, found that if snake DNA could be isolated from the bite wound, the test identified the species of snake responsible every time. "These findings represent a significant step toward improving care for patients in areas of the world where snakebites constitute a massive but neglected health risk," said Franois Chappuis, MD, PhD, chief of the division of tropical and humanitarian medicine at Geneva University Hospitals, Switzerland, who directed the study and presented the results. "This DNA test may hasten more effective bedside diagnostics for snakebite victims, giving them a better chance of surviving and making a full recovery." Bites from venomous snakes are common in many parts of the world and an especially serious unresolved health problem to millions of people living in South and Southeast Asia, as well as Africa and Latin America. Although there are … Continue reading

Yale Forms Gender Task Force Amid Scrutiny at Medical School

Posted: Published on November 5th, 2014

Yale Universitys medical school has formed a task force on gender equity amid scrutiny of the handling of a researchers accusation of sexual harassment. Yale suspended Michael Simons for 18 months as the medical schools cardiology chief last year and mandated he take sexual harassment training after complaints from a postdoctoral associate and her boyfriend, according to the New York Times. The penalty was lighter than recommended by a university committee, drawing criticism from faculty and raising questions about Yales handling of such complaints, the newspaper said. Clearly there are concerns in the medical school about the work environment, Yale President Peter Salovey said in a Nov. 2 statement. We must -- and will -- deal with inappropriate behavior consistently, no matter what position a person holds. Yale is among dozens of colleges across the country where students have filed complaints with the U.S. Education Department alleging their schools failed to comply with federal laws to prevent and appropriately respond to campus sexual misconduct. In a resolution reached with the department in 2012, New Haven, Connecticut-based Yale agreed to take a number of steps across the university to improve how it handles and reports allegations of sexual assault. The latest … Continue reading
