Traveler’s Diarrhea: The Basics
Known around the world by many names including “Montezuma’s revenge,” “Delhi belly” and “mummy tummy,” traveler’s diarrhea (TD) is the most common illness faced by travelers. Nothing can slow down a fun trip as easily as TD — and it can also have serious health implications. TD typically lasts four to six days, and 90 percent of cases occur within the first two weeks of travel.
Anatomy You Need to Know
The gastrointestinal tract starts at the mouth and ends at the anus. After food enters the mouth, it passes through the esophagus to the stomach, where it sits for approximately 45 minutes. After being broken down by gastric secretions, food matter enters the small intestine (duodenum, jejunum, and ileum in order). The small intestine is the site where most nutrients are absorbed by the body. From the small intestine, food matter begins to look more like feces as it progresses to the large intestine or colon. The colon absorbs water from the food material before the material passes through the anus and exits the body as feces.
Symptoms
Recognizing the warning signs of TD, such as blood in the stool, fever, or abdominal cramping, can help a savvy traveler know when to seek medical help.
TD has many definitions; the presence of three or more loose-formed stools in one day is a good one. Abdominal cramping, nausea, vomiting and fever may also occur. The presence of blood in the stool can indicate that infection has directly damaged the intestinal wall and should be taken seriously. Read more »

In medicine we’re often reminded not to base our therapy solely on lab test results. Although it’s tempting to reduce patient care to a checklist of “normal” bloodwork targets, we all know that this is only a fraction of the total health picture. Today I made a mistake that brought this truism home: “Don’t treat the number, treat the patient.”
I’m turning 40 this year and decided to make an ambitious fitness goal for myself — to be in better shape at 40 than I was at 30. No small feat for a person who used to be in good form a decade ago (not so much now, ahem). So, I joined a gym owned by an affable triathlete and invited her to make me her project. Let’s just say that Meredith believes that one piece of sprouted grain bread is the breakfast of champions — and with that she has me doing many hours of cardio sprints and strength training every week. I’m still alive. Barely.
Today in my endurance spinning class (an unusual form of torture where you get yelled at — I mean encouraged — on a stationary bicycle for an hour and a half in a dark room filled with high-decibel rock music and sweaty co-sufferers), I was somewhat alarmed by my heart rate. I was taught in medical school that one’s maximum heart rate is 220 minus your age. So mine should be about 180. I assumed that anything higher than that was incompatible with life.
So when I saw my heart rate monitor rise to 185 on a steep climb at maximum speed, I wondered if I might be about to die. I certainly felt physically challenged, but not quite at death’s door, so I looked around sheepishly at my nearest peer’s monitor to see if she was handling the strain any better. Nope, she was also at 185. “Gee, what a coincidence,” I thought. “We must be exactly the same fitness level.” Read more »

Via the Threatpost article “HIPAA Bares Its Teeth: $4.3m Fine For Privacy Violation“:
The health care industry’s toothless tiger finally bared its teeth, as the U.S. Department of Health and Human Services (HHS) issued a $4.3 m fine to a Maryland health care provider for violations of the HIPAA Privacy Rule. The action is the first monetary fine issued since the Act was passed in 1996.
…
A copy of a penalty notice against Cignet depicts a two-year effort in which HHS struggled with what appears to be a dysfunctional Maryland provider unaware of the potential impact of HIPAA non-compliance, and unwilling or unable to cooperate with HHS in any way.
When first reading the title I was willing to rail against HIPAA, as I’m tired of it. Then I read the post. Wow. It’s like a test case designed to see just how far you could push HHS, and frankly how incompetent you can be while pushing. Seems HHS was having trouble getting Cignet’s attention. I bet they have it now.

It’s hard to believe that turbulence could be a good thing for the heart. Consider how the word turbulent is defined: “Characterized by conflict, disorder, or confusion; not controlled or calm.” Those traits don’t sound very heart-healthy. But when it comes to heart rhythm, it turns out that a turbulent response — to a premature beat — is better than a blunted one. The more turbulent the better.
No, you haven’t missed anything, and turbulence isn’t another of my typos. Until [recently], heart rate turbulence was an obscure phenomenon buried in the bowels of heart rhythm journals.
What Is Heart Rate Turbulence (HRT)?
When you listen to the heart of a young physically-fit patient, you are struck not just by the slowness of the heartbeat, but also by the variability of the rhythm. It isn’t perfectly regular, nor is it chaotic like atrial fibrillation (AF). Doctors describe this — in typical medical speak — as regularly irregular: The heart rate increases as the patient inhales and slows as he or she exhales. This variability occurs as a result of the heart’s responsiveness to its environment. The more robustly and quickly the heart responds, the healthier it is.
HRT seeks to measure how quickly and vigorously the heart rate reacts in response to a single premature beat from the ventricle — a premature ventricular contraction (PVC). Normally after a PVC, the heart rate speeds for a few beats, and then slows back to baseline over the next 10 beats. The healthy heart responds with a more intense rise in heart rate and a quicker return to baseline. Using simple measurements of heart rate from a standard 24-hour electrocardiogram (ECG) monitor, a propriety software program averages many of these responses and comes up with a measurement of turbulence onset and turbulence slope.

Hard water is tap water that’s high in minerals such as calcium and magnesium. Hard water isn’t harmful, except the minerals prevent your soap from sudsing. Some people think that hard water is more likely to cause a rash than soft water.
Take a recent patient of mine: He moved his family to San Diego from the East Coast (good move this winter, no?) After they moved here, they noticed their skin became dry and itchy. He blamed San Diego’s notoriously hard water and installed a water softener in the main water line. It was costly, but did it improve their skin?
A recent study from the UK looked at this question: Does hard water worsen eczema? The answer was no, it doesn’t. Water hardness did not seem to have any impact on eczema, the most common skin rash.
What’s more important than the hardness of the water is the type of soap you use. True soap tends to strip the skin of its natural oils, leaving it exposed and irritated. Non-soap cleansers, of which Dove is the prototype, leave more oils on your skin, keeping it hydrated and protected.
My patient and his family didn’t get any better after installing a water softener (although he said they could drink our tap water without gagging now.) I advised him to change to a moisturizing soap and to apply moisturizer daily.
San Diego is drier than most of the country, and the low humidity can be a shock to skin accustomed to humid air. Many people who move here find they have to moisturize more often than they did back home. When they complain, I suggest they could alternatively move back to the East Coast this winter — no takers so far.
