These days hospitals drill for mass casualty disasters like the explosions at Monday's Boston Marathon. But when it happened for real, the first response was disbelief. Then the victims began arriving. Doctors say they were confronted with the kinds of IED injuries that U.S. troops have gotten in Iraq and Afghanistan.

"The top priority is diagnosis — the capability to be able to pick up this virus, should it emerge outside of China," says virologist John McCauley. Flu researchers are getting started on creating a vaccine, but there are still many unknowns.

Infants received different levels of oxygen to see which was better at preventing blindness without increasing the risk of nerve damage or death. But the federal government says doctors in the study didn't tell parents enough in advance about the "foreseeable risks" to their children.

Sixteen cases of a new flu in China have touched off a major effort to determine what kind of threat it might be. Flu experts want to know where the H7N9 virus is coming from and how it gets around.

India's Supreme Court says drug maker Novartis can't hold onto its patent for the pricey cancer drug Gleevec simply by tweaking its chemical formula. That means generic drug makers can keep making a form of the drug at a tenth of Novartis's price. Consumer advocates call it a major advance for access to generic drugs. The drug industry says it will chill companies' willingness to produce innovative products.

A study found that 1 in 5 adults ages 20 to 55 who survive strokes will die within 20 years of the event — a rate much higher than doctors expected. The findings mean doctors need to pay a lot more attention to younger stroke survivors.

The largest gene-probing study ever done has found dozens of new genetic markers that flag a person's susceptibility to breast, ovarian and prostate cancer. But knowing these susceptibility markers won't mean much for patients for now.

Researchers suggest that guidelines for regular breast cancer screening should look beyond a woman's age. Dense breast tissue, a cancer risk factor, may be a reason to consider earlier screening with mammograms.

Because dust, mold and pests can trigger asthma attacks, addressing these triggers in the home can keep kids from winding up in the hospital. In the past seven years, the Community Asthma Initiative in Boston has counseled more than a thousand families on how to prevent attacks.

French researchers confirm that the immune systems of 14 adults are apparently controlling HIV without medication. It's further evidence that early treatment may prevent the virus from establishing "reservoirs" of HIV-infected cells in the body.

Americans who suffer cardiac arrest in a hospital and are resuscitated have a 60 percent chance of being alive a year later, authors of a new study found. They also have a 45 percent chance of living for three years — better than the odds of surviving cancer.
Wednesday, March 13, 2013
Researchers in France and the U.S. say watching a resuscitation attempt doesn't have lingering bad effects on relatives — it can actually be beneficial for them. But a researcher says there will be pushback on the practice from U.S. medical personnel because of their fear of being sued.

Women who took aspirin at least a couple of times a week for five years or more cut their risk of melanoma by 30 percent. The new study adds to the mounting pile of research suggesting that cheap, common aspirin lowers the risk of many cancers, including colon, breast, esophagus, stomach, prostate, bladder and ovarian cancer.

Texas health officials have quarantined a Nepalese man, who illegally entered the U.S. while infected with a particularly dangerous type of tuberculosis. He traveled through 13 countries, potentially exposing hundreds of people around the world to the pathogen.

A child born with HIV has been cured of the virus, researchers say. Audie Cornish talks to Richard Knox about what was different about this child among the millions who've been treated in the past and what it means for the prospect of an HIV cure in adults.

Scientists say a Mississippi child has been cured of HIV. The research findings, released Sunday, could help cure other HIV-infected newborns.

Every year about 300,000 babies in sub-Saharan Africa are born with HIV. A new strategy aims to reduce these infections by putting every pregnant woman with HIV on drug treatment for the rest of her life. The approach has worked well, so far, in the small country of Malawi.

HIV has been declining in many parts of the world over the past decade. Today the U.S. unveiled an ambitious plan to stop most new HIV infections around the world. But some health leaders question whether their goals are realistic, especially with impending budget cuts.

Public health officials are trying to strike a balance between alerting, diagnosing and treating patients who might be at risk of fungal infections — and not overdiagnosing and overtreating those who aren't at risk. The caution is warranted. This type of infection can smolder for weeks before exploding into meningitis or causing massive strokes.
Thursday, October 11, 2012
Little is known about how to diagnose and treat this kind of meningitis, which was caused by a tainted drug. And the investigation into how the drug contamination occurred is revealing a spectacular failure of consumer protection.
