Scientists find new superbug strain of salmonella

LONDON (Reuters) - Scientists have identified an emerging "superbug" strain of salmonella that is highly resistant to the antibiotic Ciprofloxacin, or Cipro, often used for severe salmonella infections, and say they fear it may spread around the world. The strain, known as S. Kentucky, has spread internationally with almost 500 cases found in France, Denmark, England and Wales in the period between 2002 and 2008, according a study in the Journal of Infectious Diseases.

HIV epidemics emerging in Middle East, North Africa: study

LONDON (Reuters) - Epidemics of HIV are emerging among gay and bisexual men in the Middle East and North Africa and high levels of risky sexual behavior threaten to spread the AIDS virus further in the region, researchers said Tuesday. In the first study of its kind in a region where homosexuality and bisexuality are taboo, researchers from Weill Cornell Medical College in Qatar found evidence for concentrated HIV epidemics -- where infection rates are above 5 percent in a certain population group -- in several countries such as Egypt, Sudan, Pakistan and Tunisia.

Common vein problem raises clot risk on the Pill

NEW YORK (Reuters Health) - Women who use the standard form of birth control pill may have a much higher than average risk of dangerous blood clots if they also have a vein malformation seen in a quarter of the population, California researchers say. Up to 25 percent of the healthy population has a narrowing, known as stenosis, in the left common iliac vein (one of two major veins deep in the pelvis that return blood from the lower body to the heart), according to Dr. Lawrence Hofmann and his colleagues at Stanford University School of Medicine.

Salmonella linked to turkey sickens dozens, one dead in U.S.

SAN FRANCISCO (Reuters) - A multistate outbreak of antibiotic-resistant Salmonella believed to be linked to eating contaminated ground turkey has sickened 77 people and resulted in one known death, U.S. health authorities said. Some 26 states reported the illness between March 1 and August 1, with Michigan, Ohio, Texas, Illinois, California and Pennsylvania reporting the most cases, the Centers for Disease Control and Prevention said.

Report questions "offshoring" in U.S. heart studies

NEW YORK (Reuters Health) - Major U.S.-sponsored clinical trials on heart disease often turn to other countries to recruit patients and a new report questions whether that undermines the evidence they generate and the health of the American clinical trial system. Researchers found that of 24 U.S. taxpayer-funded clinical trials on heart disease in the past decade, 19 included patients from other countries. Across 11 of those studies, international patients accounted for nearly half of participants.

Pockets of high radiation remind of Fukushima plant danger

TOKYO (Reuters) - Pockets of lethal levels of radiation have been detected at Japan's crippled Fukushima Daiichi nuclear plant in a fresh reminder of the risks faced by workers battling to contain the worst nuclear accident since Chernobyl. Plant operator Tokyo Electric Power (Tepco) reported on Monday that radiation exceeding 10 sieverts (10,000 millisieverts) per hour was found at the bottom of a ventilation stack standing between two reactors.
