Pain in the Art
Where does it hurt? Back surgery patients have always had difficulty expressing the exact location and intensity of pain they experience. But researchers at Johns Hopkins University developed a solution by having chronic patients draw their pain. Using a computer with a human body image on it, patients point with an electronic pen to their pain areas. Doctors can then stimulate the corresponding electrodes that have already been implanted in patients’ spines, and the resulting sensation blocks their pain. Sorry, no pain-blocking electrodes yet for common ailments like headaches.
Spotting Skin Cancer
Skin cancer, something that affects some 900,000 Americans each year, is tricky to spot--even for doctors. In a recent study by UC San Francisco, primary care residents failed to diagnose malignant melanomas 40% of the time, while dermatologists failed to do so 26% of the time. If caught early, skin cancer is 100% curable, according to the study. The good news is brief training in recognizing skin cancers can improve doctors’ performance, the study showed.
Skin Cancer Avoidance
One in five men can expect to develop skin cancer at some point in their lives, according to the May issue of Men’s Fitness magazine. One blistering in childhood can double the risk of developing the condition in adulthood, the article says. Other points include: blonds and redheads are especially at risk; you can sunburn on a cloudy day; and sunscreens do not provide complete protection. Also, the left arm is one of the most common places for skin cancers because people hang their arms out the window while driving.
Risky Business
Would you take a bet that gambling disorders are on the rise in North America? Better not, even though it’s a safe bet. A Harvard Medical School study has found that the number of adults in the United States and Canada with addictions to gambling has risen significantly in recent years. Between 1977 and 1993, about 0.84% of adults suffered from the disorder, while between 1993 and 1997 the figure went up to 1.29%. The study said the greater acceptance of legalized gambling has contributed to the disorder. Have fun playing Lotto!
