While I was browsing the produce section of my grocery store the other day, the sound of a panicked voice coming over the store’s loudspeaker made me jump. “Does anyone in the store know CPR? Anyone? CPR? We need you in baked goods!”
I froze. In theory, I know how to perform CPR — cardiopulmonary resuscitation. I took a two-hour course on it nearly 25 years ago. But I hadn’t given it much thought since then and I certainly hadn’t practiced what I learned.
My mind started whirling as I tried to remember the sequence of steps. They’d changed the rules a few years back — I knew that much — so I wouldn’t have to do mouth-to-mouth resuscitation. But where exactly on the chest was I supposed to push? Should I form a fist and push down with my knuckles, or use the ball of my hand?
Suddenly, sirens wailed outside the store. The rescue squad had arrived. Too late, as I learned afterward, for this man, who was a victim of a sudden cardiac arrest. This type of heart attack strikes so fast that there usually aren’t any warning signs. You might see someone grasp his or her chest, collapse, twitch and gasp a few times, and then lie deathly still.
At that point, every minute counts. Enough oxygen remains in the person’s bloodstream to nourish the brain for several minutes — but a bystander has to circulate oxygenated blood to the brain and other organs by pushing down on the chest hard and fast, mimicking the heartbeat.
I’m a health writer. I knew this intellectually. But until those agonizing moments in the grocery store, I never really understood on a gut level just how important every minute is. Read more »

News that tennis star Serena Williams was treated for a blood clot in her lungs is shining the spotlight on a frightfully overlooked condition that can affect anyone — even a trained athlete who stays fit for a living.
Williams had a pulmonary embolism. That’s doctor speak for a blood clot that originally formed in the legs or elsewhere in the body but that eventually broke away, traveled through the bloodstream, and got stuck in a major artery feeding the lungs. (To read more about pulmonary embolism, check out this article from the Harvard Heart Letter.) Pulmonary embolism is serious trouble because it can prevent the lungs from oxygenating blood — about one in 12 people who have one die from it.
“No one is immune from pulmonary embolism, not even super athletes,” says Dr. Samuel Z. Goldhaber, professor of medicine at Harvard Medical School and one of the country’s leading experts in this clotting disorder.
Pulmonary embolism tends to happen among people who have recently had surgery, been injured, or been confined to bed rest for some time. It can also strike after long-haul flights.
Signs of a PE
How do you know if you’re experiencing a pulmonary embolism? The most common symptoms include shortness of breath when you aren’t exerting yourself, along with chest pain and coughing up blood. If you experience any of these symptoms, see a doctor immediately. Other worrisome signs include:
- Excessive sweating
- Clammy or bluish skin
- Light-headedness
- Fast or irregular heartbeat
The tennis star’s pulmonary embolism could have been the result of the perfect storm. After having a cast removed from a foot she cut at Wimbledon, Williams flew from New York to Los Angeles. It was in LA, after an appearance at the Oscars ceremony on Sunday, that she underwent emergency treatment at Cedars Sinai Hospital for a blood clot in her lungs.
A call to action by the U.S. Surgeon General says that pulmonary embolism and a related condition — deep-vein thrombosis — affect an estimated 350,000 to 600,000 Americans each year. Together, they account for somewhere between 100,000 and 180,000 deaths each year.

Good news for parents, teachers, pediatricians, and others engaged in the ongoing battle against lice: The Food and Drug Administration (FDA) just approved a new treatment for head lice in children age four and older. Called Natroba, it’s a liquid that is rubbed into the hair and allowed to sit for 10 minutes before being rinsed off. Natroba is a useful addition to the anti-lice arsenal, since some head lice have become resistant to permethrin and pyrethrins, the active ingredients in over-the-counter anti-lice products such as Nix and Rid.
Head lice are tiny insects that go by the big name Pediculus humanus capitis. They thrive in the warm tangle of human hair, feeding off blood in the scalp and breeding with abandon. A female lays eggs called nits that she attaches to strands of hair. Nits hatch after about eight days, become adults in another week or so, feed for awhile, then begin to make more lice.

What To Do
First off, here’s what not to do: Don’t shave your or your child’s head, or coat it with petroleum jelly or mayonnaise or anything else designed to “suffocate” the parasite. You’ll probably end up with greasy, smelly, lice-infested hair.
Current guidelines from the American Academy of Pediatrics call for the use of an over-the-counter product containing permethrin or pyrethrins as a first salvo against head lice. Shampoos and rinses made with these substances are generally effective. Most treatments for head lice need to be used twice, seven to 10 days apart, along with combing wet hair with a fine-toothed nit comb. Some lice are resistant to pyrethrin and permethrin. Stronger prescription drugs, such as malathion and lindane, also work but aren’t as safe for humans. That’s where Natroba comes in. Read more »

Stroke killed 2,000 fewer Americans in 2008 (the last year with complete numbers) than it did in 2007, the Centers for Disease Control and Prevention (CDC) said yesterday in its latest annual Deaths report. That dropped stroke from the third leading cause of death in the United States to the fourth.
Good news? Yes and no. It’s always good news when fewer people die. The reduction suggests a payoff for efforts to prevent stroke and improve the way doctors treat it.
Yet the drop from third to fourth place is due largely to an accounting change. The CDC reorganized another category, “chronic lower respiratory diseases” (mainly chronic bronchitis and emphysema), to include complications of these diseases such as pneumonia. The change substantially increased the number of deaths in this category, which had long trailed stroke as the fourth leading cause of death.
More worrisome is that the decline in deaths from stroke isn’t matched by a decline in the number of strokes. On the rise since 1988, stroke now strikes almost 800,000 Americans a year, and that is expected to grow. Read more »
