Come summertime, some of us here at Shots are reminded, as we lounge on decks and venture into overgrown gardens, that we are irresistible to mosquitoes. As we gripe about our itchy, pocked limbs, we can't help but wonder just why they unfailingly devour us and pass over our friends and loved ones. And when it comes to repellent, it's hard to tell just what works best.
Menthol gives cough drops, lip balm and other drugstore remedies that cool minty taste and slight numbing quality. Now the Food and Drug Administration has taken a long-awaited step toward saying that in cigarettes, those same qualities do more harm than good.
Not so long ago, most people thought that the only good microbe was a dead microbe.
But then scientists started to realize that even though some bugs can make us sick and even kill us, most don't.
In fact, in the past decade attitudes about the bacteria, fungi, viruses and other microbes living all over our bodies has almost completely turned around. Now scientists say that not only are those microbes often not harmful, we can't live without them.
Sickle cell anemia may not be as well-known as, say, malaria, tuberculosis or AIDS. But every year, hundreds of thousands of babies around the world are born with this inherited blood disorder. And the numbers are expected to climb.
The number of sickle cell anemia cases is expected to increase about 30 percent globally by 2050, scientists said Tuesday in the journal PLOS Medicine. Countries in sub-Saharan Africa, where the disease is most common, will be the hardest hit.
The newest co-host for Barbara Walters' chatfest The View is a vivacious and outspoken model, actor and activist for children, seemingly a perfect person to have at the table of the successful network talk show.
But Jenny McCarthy is also one of the nation's leading skeptics about the safety of vaccines. And in that role, ABC's newest star has stirred consternation.
Uncle Sam wants your doctor to go digital. And the federal government is backing that up with money for practices that start using computerized systems for record keeping.
Nearly half of all physicians in America still rely on paper records for most patient care. Time is running out for those who do to take advantage of federal funds to make the switch. So practices like Colorado Springs Internal Medicine are scrambling to get with the program.
Every year more than a quarter of a million Americans have total hip replacement surgery. It's almost always a successful operation that frees patients from what's often described as disabling pain.
But in recent years, there's been lots of discussion on the Internet about "anterior approach" hip replacement, a surgical technique that's different than the standard procedure. It's one that proponents say can lead to quicker recovery, three to four weeks compared to six to eight weeks for typical surgery.
Anybody who has ever worn a cast knows that it can really cramp your style. You itch. After a while, you stink. At times, it seems like the cast needs even more care than you do. Keep it dry or else!
Other than the addition of garish colors of fiberglass, there hasn't been much innovation in cast technology in what seems like forever. But down in New Zealand, designer Jake Evill is bringing the latest in 3-D printing to orthopedics.
Dr. Linda Smith walks into a room at Providence Alaska Medical Center, ready with a stethoscope and a huge grin. She teases her patient, Dawn Dillard, saying that her spiky hair recently resembled a "faux hawk."
Dillard found out she had uterine cancer a year ago. Her oncologist gave her a year to live. The 57-year-old has beaten those odds, but now her kidneys are failing. After the laughs are over, Smith sits down on the edge of Dillard's bed, leans in, and starts talking about a procedure Dillard will have.
