Researchers at MIT have developed a method of using a basic cellphone coupled with a cheap and simple plastic device clipped onto the screen to estimate refractive errors and focal range of eyes.
Because of its simplicity, and the fact that soon just about everyone will have access to a mobile phone, eye exams may become available to the whole world at little to no cost. Read more »

People aren’t dumb. Even if — or maybe especially if — news stories don’t point out the limitations of observational studies and the fact that they can’t establish cause-and-effect, many readers seem to get it.
Here are some of the online user comments in response to a CNN.com story that is headlined, “Coffee may cut risk for some cancers“:
* “I love how an article starts with something positive and then slowly becomes a little gloomy. So is it good or not? I’m still where I was with coffee, it’s all in moderation, it ain’t gonna solve your health woes.”
* “The statistics book in a class I’m taking uses coffee as an example of statistics run amuck. It seems coffee has caused all the cancers and cures them at the same time.” Read more »

Talk about a cruel trick of nature! A study funded by the National Institutes of Health (NIH) and published in the Journal of the American Medical Association (JAMA) shows that physical activity prevents weight gain in middle-aged and older women ONLY IF THEY ARE ALREADY AT IDEAL WEIGHT. Did you read that? It means that the recommended guidelines advocating 150 minutes of exercise a week isn’t sufficient to prevent weight gain in most middle-aged women.
The Harvard-associated researchers assessed weight changes associated with various levels of physical activity on 34,079 women who had been followed since 1992 in the Women’s Health Study. They stratified women as “inactive” (less than 150 minutes a week of moderate level physical activity), “intermediately active,” or “highly active” if they performed a high, strenuous level of activity. All three groups showed similar weight gain over a mean of 13 years of follow up. Read more »

Remember “cooties” in grade school? You know, the germs or disease that girls gave boys or boys gave girls in grade school if they touched? Well, it seems they’re becoming an epidemic. Thank goodness someone checked for “cooties” on the Stanley Cup:
The NHL champion Blackhawks’ beloved trophy stopped by the Chicago Tribune newsroom, and so we took the opportunity to do something the Cup’s keeper said had never been done: We swabbed it for germs. We sent the samples to the Chicago lab EMSL Analytical, which found very little general bacteria and no signs of staph, salmonella or E. coli. “It’s surprisingly clean,” lab manager Nancy McDonald said. Just 400 counts of general bacteria were found, she said. By comparison, a desk in an office typically has more than 10,000.
No staph species detected? Hmmm. I think there was a sampling error…

It’s no secret that the U.S. has a weight problem and with chain restaurants serving up meals with thousands of calories in a single dish, it’s easy to understand why. Watch “CBS Doc Dot Com” to see which meals you should try to avoid — or at least share.
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…

Book Review: Is Empathy Learned By Faking It Till It’s Real?
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…
The Spirit Of The Place: Samuel Shem’s New Book May Depress You
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…
Eat To Save Your Life: Another Half-True Diet Book
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…
