If you want to live longer -- avoid heart disease, Alzheimer's disease and cancer -- then pick and choose your foods with care to quiet down parts of your immune system. That's the principle promoted by the founders and followers of anti-inflammatory diets, designed to reduce chronic inflammation in the body. Dozens of books filled with diets and recipes have flooded the market in the last few years, including popular ones by dermatologist Dr. Nicholas Perricone and Zone Diet creator Barry Sears.

The Food and Drug Administration approved a radical and controversial treatment for crippling chest pain Thursday: a laser that zaps up to 40 tiny holes into the heart itself. The heart laser is only for the small proportion of heart patients who have a debilitating type of chest pain called stable angina that is not helped by conventional therapy, the FDA stressed.

SHAM medicines can sometimes bring real pain relief. Now scientists say they know why. New research shows that the "placebo effect" has a real physiological basis: It triggers the brain's pain-fighting chemicals. The findings could boost the search for drug-free ways to treat pain. "Just the expectation of pain relief is enough to activate anti-pain mechanisms," says lead scientist Jon-Kar Zubieta, a neuroscientist at the University of Michigan in Ann Arbor.

CardioGenesis Corp.'s stock suffered Tuesday's worst pummeling on Wall Street--losing 71% of its value--a day after the medical-device company revealed that a federal panel failed to back its latest laser treatment for heart patients. Shares of the Foothill Ranch company plummeted $2.04 to close at 85 cents on Nasdaq, the largest percentage loss on U.S. markets Tuesday. During trading, the price had fallen to 76 cents a share.

Traditional acupuncture treatments for migraines are no better at reducing pain than sham acupuncture treatments, researchers have found, contradicting earlier research. But, in an unexpected twist, both methods appear to significantly reduce migraine frequency. "Sham acupuncture seems to be very potent compared to no treatment," said lead researcher Klaus Linde, a clinical epidemiologist at the Technische Universitat Munich in Germany.

Psychosomatic illnesses shouldn't be confused with imagined conditions. Helping those who imagine or feign illness is different from -- and harder than -- treating psychosomatic illness, says Dr. Marc Feldman, a nationally known expert in psychosomatic medicine. "We're probably more advanced right now in understanding the brain-body connection. But when you talk about the mind and the role of fantasy, we're a long way off," he says. Hypochondria is a particularly vexing problem.

For a muscular agency that combats vicious drug criminals, the U.S. Drug Enforcement Administration acts like a terrified and obstinate toddler when it comes to basic science. For years, the DEA and the National Institute for Drug Abuse have made it all but impossible to develop a robust body of research on the medical uses of marijuana. A pro-marijuana group lost its legal battle this week when a federal appellate court ruled that marijuana would remain a Schedule I drug, defined as having no accepted medical value and a high potential for abuse.

This might be tough for parents who want to swoop in and fix their children's every problem, but a study found that half of the teenagers who screened positive for depression got better in six weeks without treatment. Two aspects of the teenagers' conditions seemed to predict whether the depression would ease without treatment: the severity of the symptoms and whether the symptoms persisted for six weeks, the researchers, led by Dr. Laura Richardson of Seattle Children's Research Institute, said in an article published this week in the journal Pediatrics.

Paging Stacy London and Clinton Kelly: Apparently dermatologists need some help in deciding what to wear when they see patients. The biggest controversy appears to involve whether skin specialists should wear their iconic white coats into the exam room or leave them in their offices. A survey reported this week in Archives of Dermatology found that 54% of adult patients want their dermatologist to wear the coats; however, only 26% of parents who brought their children to a pediatric dermatologist think the white coat is helpful in that setting.

Ten years ago, researchers stumbled onto a striking finding: Women who believed that they were prone to heart disease were nearly four times as likely to die as women with similar risk factors who didn't hold such fatalistic views. The higher risk of death, in other words, had nothing to with the usual heart disease culprits--age, blood pressure, cholesterol, weight. Instead, it tracked closely with belief. Think sick, be sick.
