What your next gyno exam may not include

For doctors, pelvic examinations are a routine way to screen for abnormalities. But for many women, the procedure is uncomfortable and embarrassing.

Thanks to a new clinical practice guideline by The American College of Physicians, your next annual check-up might be less... invasive.

After reviewing 52 studies, the physicians organization concluded that annual pelvic examinations - in non-pregnant, adult women who do not have symptoms - are unnecessary. In other words, pelvic screening exams have served their time.

Study: 1/3 of knee replacements are questionable

Whether to replace aging knees can be a tough decision. More than 650,000 Americans underwent total knee replacement surgery last year, but a new paper from researchers at Virginia Commonwealth University suggests that a third of those were not “appropriate,” based on standard medical criteria.

The study authors analyzed 175 cases, looking at imaging tests to find the degree of arthritis, as well as each patient’s age and reported pain level. Only 44% of the operations were rated “appropriate.” Thirty-four percent were “inappropriate,” while 22% were inconclusive.

But appropriateness is in the eye of the beholder, says Dr. Jeffery Katz, an orthopedic surgeon at Brigham and Women’s Hospital in Boston. When the current criteria were developed in the late 1990s, knee replacement “was considered a treatment of last resort,” Katz writes in an editorial published alongside the study in the Journal of Arthritis and Rheumatism. Today, many are being done in relatively healthy people in their 50s and 60s.

Have you had the 'sext' talk with your kids?

Have you had the 'sext' talk with your kids?

It’s called sexting, the act of sending and/or receiving sexually explicit text or photo messages via your mobile phone. And one in five middle school-aged students are doing it, according to a new study published in the medical journal Pediatrics.

Among the 1,285 Los Angeles students aged 10 to 15 surveyed for the study, 20% reported having received at least one sext, while 5% reported having sent at least one sext.

“Very frequently it’s the image or the sex, that is finding its way to the middle schooler first, prior to any sort of conversation or education" by parents, said Ian Kerner, a sexuality counselor and father to two boys. "That makes it even more confusing (for kids).”

The study authors also looked at how sexting relates to sexual behavior among these adolescents. The survey showed that those who reported receiving a sext, were six times more likely to report being sexually active than teens who hadn't received a sext. Those who sent a sext were about 4 times more likely to report being sexually active.
