In a recent article, the editors of the Archives of Internal Medicine make the case that too much unneeded care is being delivered in physician’s offices these days. According to the authors, “patient expectations” are a leading cause of this costly problem.
Their solution? Get physicians to share with patients the “evidence” for why their requests are crazy, wrong, ill-informed or just plain stupid. But getting patients to buy into the “less is more” argument is a daunting task as most physicians already know. The problem is complicated by the fact that patients have a lot good reasons for not buying it. Read more »

Research scientists at the Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, have developed a helmet that will make you think twice about continuing to cycle with a damaged helmet.
For maximum protection, safety helmets need to be damage-free, but it’s often impossible to know if a helmet is actually flawed after it’s been dropped or hit by something. The researchers have used polymers that start to smell if there are any small cracks, and will really stink in the case of any large cracks. Read more »

The underwear project, spearheaded by the nanoengineering professor, was funded by the U.S. military and its effectiveness will likely be tested on the battlefield.
“This specific project involves monitoring the injury of soldiers during battlefield surgery,” Wang told Reuters. “The goal is to develop minimally invasive sensors that can locate, in the field, and identify the type of injury.”
Ultimately, the waistband sensors will be able to direct the release of drugs to treat the wounded soldier.
I wonder what other creative uses our men in uniform will find for this? I can hear it now: “It’s not the size of the device, honey, it’s the metronome that’s in it!” (Heh.)

“Short people have higher heart risk” screams the headline on CNN.com, treating it as a statement of fact. “Shortness Boosts Heart Disease, Death Risk” is the headline in a HealthDay story seen on BusinessWeek.com.
Wrong.
Such a study as the one being described can only establish association — it CANNOT prove causation. So it’s wrong to say short people have higher risk. It is wrong to say shortness boosts risk.
Blogger and cardiac electrophysiologist Dr. Wes Fisher beat me to the punch by blogging about the continued journalistic confusion between association and causation. He wrote:
“About the only thing that can be concluded from this so-called “analysis” is nothing more than maybe we should consider studying if this association actually exists.”
Tell ’em, Dr. Wes. And tell ’em, Randy: “Short people got no reason” to worry — at least not yet — from this study.
The Journal of Allergy and Clinical Immunology is the official publication of the American Academy of Allergy, Asthma and Immunology, and a good example for all medical and scientific journals about how they should embrace social media:

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…
