China media train fire on U.S. food giants over chicken scare
SHANGHAI (Reuters) - Just weeks after Chinese authorities cleared Yum Brands Inc <YUM.N> and McDonald's Corp <MCD.N> of charges they had served chicken laced with excessive chemicals, local media are again attacking the iconic American firms, while barely reporting on the chances of Chinese restaurants selling similar meat. The official Shanghai Daily, citing a report from the central government's news portal china.com.cn, said on Thursday one of China's largest suppliers to McDonald's and Yum's KFC and had bought sick chicken from farms and sold them to the food outlets - a claim a local government in the central province of Henan said was untrue after a preliminary investigation.
Vaccine timetable for children is safe, experts say
WASHINGTON (Reuters) - The current guideline for immunizing children against polio, whooping cough, measles and other infectious diseases is safe, but should still be monitored, federal health advisers said on Wednesday. In what they called the most comprehensive review to date, scientists at the Institute of Medicine (IOM) said there is no evidence that giving children vaccines according to the recommended timetable causes other problems such as autism or asthma.
Governors in 22 states back expanded Medicaid plan
WASHINGTON (Reuters) - At least 22 governors, including four Republicans, support an expansion of Medicaid under President Barack Obama's healthcare reform law, while others are expected to decide in the coming weeks, experts said on Wednesday. An analysis published by the New England Journal of Medicine said the headcount, which includes 13 Republican governors who staunchly oppose Medicaid expansion, portends an uneven start for "Obamacare" when its most sweeping reform provisions begin on January 1, 2014.

NEW YORK (Reuters Health) - Having step-by-step checklists on hand may help doctors and nurses manage emergencies in the operating room, a new study suggests.

Skin cancer phone apps aren't very accurate: study
NEW YORK (Reuters Health) - Smartphone applications that use algorithms to analyze skin lesions may not be very good at determining which ones are cancerous, a new study suggests.

Feces transplant may help relieve severe diarrhea
NEW YORK (Reuters Health) - It may sound like the most unappealing treatment available, but a small new study has concluded that inserting fecal material from a healthy person into the gut of someone with severe diarrhea may cure their problem more effectively than antibiotics. The study, which appears in the New England Journal of Medicine, involved patients who had repeated bouts of diarrhea caused by a bacterium known as Clostridium difficile. So-called C. diff can take over the intestines after antibiotic treatment has killed off the beneficial bacteria found in the gut.
Dengue is fastest-spreading tropical disease, WHO says
GENEVA (Reuters) - Dengue is the world's fastest-spreading tropical disease and represents a "pandemic threat", infecting an estimated 50 million people across all continents, the World Health Organization (WHO) said on Wednesday. Transmitted by the bite of female mosquitoes, the disease is occurring more widely due to increased movement of people and goods - including carrier objects such as bamboo plants and used tires - as well as floods linked to climate change, the United Nations agency said.
