My friend and fellow medblogger Jan Gurley has participated in two mission trips to Haiti this year. On her blog she describes the shocking living conditions that she encountered, including a new outbreak of cholera. Cholera can kill a person in as few as three hours by causing the body to loose all its fluid through the intestines.
Fluid replacement is the key to surviving cholera, though plain water lacks the electrolytes necessary for sustaining life. With just four bottle caps of sugar and one bottle cap of salt in half a liter of water, you can create lifesaving oral rehydration therapy. No need for Gatorade — Dr. Gurley shows you how in this video (please pass it on):
Rates of rectal cancer in those younger than 40 have been increasing, the LA Timesreported recently.
Researchers studied data from the Surveillance, Epidemiology and End Results (SEER) Registry and looked at the change in rectal and colon cancer incidence in those under 40 from 1973 to 2005. Overall rates were low, but while colon cancer incidence remained constant, rectal cancer incidence increased by an average of 3.8 percent annually, the authors reported in the journal Cancer.
The authors didn’t advocate routine screening in those under 40, but did recommend that physicians be more alert to the possibility of rectal cancer in those presenting with symptoms such as rectal bleeding, according to the Times. (LA Times)

Dr. Mehmet Oz just might be the last person on earth people would expect to get a colon polyp. He’s physically fit (he left me in the dust the last time we ran together), he eats a healthy diet, he doesn’t smoke, and he has no family history of colorectal cancer or colon polyps.
But several weeks ago, when Mehmet had his first screening colonoscopy at age 50, I removed a small adenomatous polyp that had the potential to turn into cancer over time. Statistically, most small polyps like his don’t become cancer. But almost all colon cancers begin as benign polyps that gradually become malignant over about 10 to 15 years.
Since there’s no way of knowing which polyps will turn bad, we take them all out. The good news is there’s plenty of opportunity to prevent cancer by removing these polyps while they are still benign. But only about 63 percent of Americans between ages 50 and 75 get screened for colorectal cancer. Read more »
University of Florida researchers have developed a signaling technology that can be embedded into drug tablets to notify clinicians and caretakers that a pill has been ingested.
Although a bit of electronics is going to be moving through the digestive system, the researchers believe that it will pass safely without causing side effects to the patient.
If the technology proves itself, it may soon be used to confirm compliance in clinical trials or to monitor patients under a strict drug regimen.
One part is the pill, a standard white capsule coated with a label embossed with silvery lines. The lines comprise the antenna, which is printed using ink made of non-toxic, conductive silver nanoparticles. The pill also contains a tiny microchip, one about the size of a period on paper.

April is “Embarrassing Subject Month” for my podcast. I am covering the following problems:
Hemorrhoids
Digestive problems (constipation/diarrhea)
Urinary incontinence
“Male problems”
It should be fun, and it will be promoted on iTunes, so it should drum up more subscribers and downloads.
But it begs the question: Why are certain conditions embarrassing to people? Why can people open up to me about so many personal things, yet be embarrassed to discuss hemorrhoids? Why is it easier to talk about your marriage falling apart than your urinary “accidents?” Why is diarrhea more embarrassing than vomiting? Read more »
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…
