Japanese officials are preparing to distribute potassium iodide pills to people living near the nuclear power plants crippled by last week’s earthquake. Harvard Health Letter editor Peter Wehrwein explains what these pills do and who needs them.
Getting the viral infection known as shingles doesn’t give everyone life-long immunity from it. As many as 1 in 20 people suffer through it a second time. What researchers don’t yet know is whether it makes sense to get the anti-shingles vaccine after you’ve had this painful condition.
The King’s Speech has won almost universal praise for its portrayal of reluctant monarch George VI’s stuttering. Harvard Health Letter editor Peter Wehrwein takes you behind the scenes with Alex Johnson, an expert in speech and stuttering at the MGH Institute of Health Professions in Boston; Caroline Bowen, an Australian speech-language therapist; and a few other scattered sources.
Tomorrow night at 6:30 p.m., tens of millions of television sets will be turned on as Americans sit down and participate in that unofficial national holiday called “watching the Super Bowl.” For many, it’s an excuse to see funny ads and the half-time show and to eat (how many of those spanking new Dietary Guidelines will be broken?), drink, and socialize.

It depends on what you mean by “work.” Results reported in today’s Annals of Internal Medicine found that echinacea may reduce the length of a weeklong cold by 7 to 10 hours and make symptoms a little less onerous.

Vitamin D has been talked about as the vitamin — the one that might help fend off everything from cancer to heart disease to autoimmune disorders, if only we were to get enough of it. “Whoa!” is the message from a committee of experts assembled by the Institute of Medicine (IOM) to update recommendations for vitamin D (and for calcium).

Lung cancer is usually discovered late when it’s difficult to treat and has often spread outside the lung. A reliable screening test to find it at an earlier, more treatable stage would be a legitimate breakthrough—and could potentially save thousands of lives. About 160,000 Americans die each year from lung cancer, which is more than who die from breast, prostate, and […]
Trick or treat? It’s really a rhetorical question. They just want the Halloween candy. Millions of American children will get billions of sugar- and fat-laden treats on Sunday night in a tradition that has its roots in pagan and Christian rituals. It’s fun. The kids are outside, walking. And, gosh, they’re cute in their princess and pirate costumes. But nutritionally and dentally speaking, the […]
