Male readers be advised! Using your laptop placed on your knees to read this post may cause your testicles to heat up quite significantly. However surprisingly, this is not due to the heat dissipated by many laptops, but rather due to the positioning of the legs. A study just published online in the journal Fertility and Sterility investigated ways to avoid the testicles from overheating while using a laptop computer.
Right and left scrotal temperatures were measured in 29 volunteers while working on the laptop in different positions: With closely approximated legs, with closely approximated legs with a lap pad below the laptop, and sitting with legs apart at a 70° angle with a lap pad below the laptop. After 60 minutes with closed legs, temperature increased about 2.4 degrees Celsius, using the lap pad yielded a slightly smaller increase of 2.1 degrees, while spreading the legs resulted in a modest increase of 1.4 degrees.
The authors conclude that prevention of scrotal hyperthermia in laptop users is not feasible, although we would like to disagree and suggest using a flat surface, such as a table or desk, to position your laptop in order to preserve your fertility.
The Chilean mine rescue was a great example of international cooperation and effort, much like the International Space Station. Another similarity between the two was some of the physicians involved.
Dr. J.D. Polk and other flight surgeons at NASA had, years ago, made a contingency plan for how to make the limited Space Station food stores last for months if there was a problem with re-supply. So when the Chilean government asked if NASA had any advice for how to care for the miners trapped in a similar resource-limited setting, Dr. Polk and a team went down to help, and MedPage Today wrote up a great summary of their efforts.

Remember that cold December in 1999 when we all thought that planes would soon be dropping out of the sky, nuclear power plants were to be melting down, and the world was going to end? This weekend Health Canada is giving clinicians across the country (and really all of North America) an opportunity to feel the anxiety, fear, and excitement all over again.
In 2007, the dates for switching between Standard and Daylight Saving time were changed, and the authorities, three years into the new schedule, have issued a warning for this weekend’s one hour rollback:
Medical equipment manufactured prior to 2007 may not function optimally if the equipment has not been updated by manufacturers to compensate for the new dates.
To date, Health Canada has not received any reports of device malfunctions because of the revised time change that began in 2007. However, examples of medical devices that could be affected by the change include (but are not limited to): implanted pacemakers/defibrillators with sleep modes that can only be adjusted by physicians; Holter monitors, used to continuously record heartbeat; and glucose monitors that store data on glucose levels.
If a medical device displays the incorrect time after 2:00 a.m. on Sunday, November 7, 2010, users should contact the manufacturer to bring the problem to their attention and consult a health care professional.
We’ve written before about HealthMap, a project spearheaded by folks from Harvard, Children’s Hospital-Boston, and a few other institutions. At TEDMED 2010 we had a chance to interview John Brownstein, co-founder of the project, about what HealthMap is up to these days:
To promote his new zombie book, “Rise Again,” author Ben Tripp is offering a printable sheet of flesh wounds that, to our relatively trained eyes, are reasonably accurate depictions of what undead flesh wounds would look like. You have to provide your own sticky sheets to print them on. (Note to medical students: Do not stick these on your anatomy cadavers.) Happy Halloween!
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…
