I have seen several searches of this blog for the BNHS and wondered why. The answer: The site no longer carries the wonderful show, for reasons unknown to me. As for the searches, I guess the Christmas season has people thinking about sexually-transmitted infections (STIs) set to a Christmas tune.
Merry Christmas!

Scientists have discovered a new, highly-transmissible gene that could, quite easily in fact, open a frightening new front in the ongoing global war against superbugs.
The antibiotic-resistant gene, NDM-1, was first identified in 2008 a Swedish patient that had received hospital care in New Delhi. NDM-1 produces an enzyme that allows bacteria to destroy most antibiotics. It exists on plasmids, which are pieces of genetic material that are easily shared between bacteria including E coli and other species that can cause pneumonia, urinary tract infections, and blood stream infections.
NDM-1 probably evolved in parts of India where poor sanitation and overutilization of antibiotics provide a perfect environment for the creation of antibiotic-resistant bacteria.
The gene has been identified in three U.S. patients. All had received medical treatment in India, and all recovered from their infections. It has been found sporadically in Britain, Australia and nearly a dozen other countries as well. Most affected patients were “medical tourists” — that is, people seeking less expensive medical care in India.
“We need to be vigilant about this,” said Arjun Srinivasan, an epidemiologist at the CDC told the Washington Post. “This should not be a call to panic, but it should be a call to action. There are effective strategies we can take that will prevent the spread of these organisms.” Read more »

Everyone knows that when it comes to germs and kids, it can sometimes be difficult to limit the spread of infection — especially in a school or daycare setting. In this video, I talked with local TV news last week about germs and kids, and about preventing infections in college students during finals week:

Potential health effects of airport security are being questioned for their possible health consequences, from spreading germs to radiation exposure to the stress that being searched induces.
With cheaper flights available this year and the need for security in air travel, the Transportation Security Administration (TSA) is justifying its full body scans and its pat-downs that rise up travelers’ legs — all the way up.
The scanners use microwaves, leading some to question whether people may be receiving too much radiation. It’s also a concern to activists who may have already undergone a lot of radiation for existing condition, or who have other conditions for which TSA agents may not be trained. (Read one seasoned traveler’s personal experience here.) The TSA reports the scanners expose users less energy than a cell phone.
Some protesters refused the body scans in favor of a pat-down, in an effort to tie up air travel on the day before Thanksgiving and force a review on the issue. But a manual exam spreads germs, say others.
Amid all the speculation of potential health consequences, federal officials are reminding travelers that the security measures are there for passenger safety. However, retorts Jason Mustian‘s Twitter feed, “Body scans and genital fondlings would save more lives if our government was paying to have them done in hospitals rather than airports.”

Kids get inner ear infections and then they get antibiotics, despite a long-standing knowledge that it’s not always best. Any physician knows this, but who hasn’t faced an irate or anxious parent in the exam room insisting on a prescription, whether the evidence warrants it or not?
Reuters reports that the tally for all those antibiotics is $2.8 billion dollars, or $350 per child annually. And there’s only a slight benefit to them.
While hardly comforting to the parents, physicians can add more heft to their argument that antibiotics are only modestly more effective than nothing, and they can avoid the rashes and diarrhea that antibiotics incur. Read more »

Healthy VisionTM with Dr. Val: Safe Contact Lens Wear and Care
It’s no secret that doctors are disappointed with the way that the U.S. healthcare system is evolving. Most feel helpless about improving their work conditions or solving technical problems in patient care. Fortunately one young medical student was undeterred by the mountain of disappointment carried by his senior clinician mentors…
I am proud to be a part of the American Resident Project an initiative that promotes the writing of medical students residents and new physicians as they explore ideas for transforming American health care delivery. I recently had the opportunity to interview three of the writing fellows about how to…
I m often asked to do book reviews on my blog and I rarely agree to them. This is because it takes me a long time to read a book and then if I don t enjoy it I figure the author would rather me remain silent than publish my…
When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…
I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
