It could be a common dry skin rash called pityriasis alba.
With pityriasis alba, the white patches of fine dry scale are usually located on the sides of the cheeks and the outer side of the upper arm. They’re more likely to occur when activities or weather conditions dry out the skin such as swimming in chlorinated pools or with the temperature extremes of a cold and dry winter. They also show up more when skin is tanned because the scaly patches stay white and contrast against the tanned skin. That means that towards the end of summer, they may well be in full bloom if you live in a dry climate.
What is pityriasis alba?
It’s a subtle form of eczema (also called dermatitis). It’s an unusual rash though because there really isn’t much, if any, inflammation. This means the involved skin doesn’t itch, it just looks funny. Most people mistake it for a fungus, which it isn’t. It’s just a form of dry skin eczema.

With the release of the movie Contagion, I thought it would be appropriate to post my cheat sheet on how to investigate a disease outbreak. Aspiring disease detectives take notes!
What do you think of when you hear the word “outbreak”? Maybe you envision a population decimated by a terrible, novel, and incurable disease like in the aformentioned movie Contagion or you think of Dustin Hoffman roaming around California in a blue biocontainment suit with Rene Russo trying to protect folks from a tiny monkey and narrowly preventing an airstrike by the US military?
Hollywood has done their best to capture what an outbreak is…but here are the facts. An outbreak, or epidemic, occurs when there are more cases of disease than would normally be expected in a specific time and place. The disease may be something doctors have already seen before just in a new form or abnormally high numbers, such as foodborne or healthcare-associated infections, or it may be an emerging disease that we don’t know much about like SARS. Either way, we need to investigate to determine why it is happening and how to prevent other people from getting sick or dying. 
Outbreaks are usually noticed by an astute clinician, such as those who first noticed AIDS in New York City and San Francisco, but there are also many high tech disease detection systems available to help us spot any increase in illness. PulseNet is a laboratory network that uses PFGE (pulsed-field gel electrophoresis) to help identify foodborne outbreaks by monitoring the genetic make-up of the bacteria causing what may otherwise look like unrelated illnesses. In the recent events of the Salmonella outbreak in ground turkey, PulseNet and the National Antimicrobial Resistance Monitoring System helped identify the cause of the outbreak as well as determine how widely it had spread. Programs such as Biosense and First Watch monitor the chief complaint or reason that someone called 9-1-1 or went to the hospital (aka syndromic surveillance). We also monitor news media for reports of outbreaks and websites such as Google Flu trends, which tracks circulating viruses and illnesses. With new technology ordinary citizens can also increasingly report outbreaks in their communities too.
The Magic Formula
So how do you figure out the who, what, when, and where of a disease outbreak? Read more »

Before I even start, let me say this to my triathlete friends…
I really like you all. And…I am sorry for how I feel about your sport’s pinnacle, the Ironman triathlon. But I was poked into writing this post. When asked the question of whether the Ironman is safe for the middle-aged heart, what was I to do? Lie?
Each August, my hometown, Louisville, KY, gets overrun, over-swum and over-ridden with “Iron people.” No, these humans aren’t rust colored, or all that hardened, but they are indeed a determined lot. Triathletes, or iron people if you will, wake up before sunrise to swim, bike or run. Then they eat; some go to work (barely), and then they do the training thing again in the evening. Calling these athletes focused would surely be an understatement.
So it is each summer that I endure the same question: “Dr. Mandrola, did you do the Ironman?”
“No…I just ride bikes.”
But this year was different. Before I could launch into my usual dissertation on how training for Ironman-length triathlons causes excess inflammation, coronary calcium, atrial fibrillation, divorce, etc., etc., another question quickly popped up.
“What did you think of that guy who died during this year’s race?” Read more »

It isn’t easy to get rid of a harmful habit like drinking too much, or to make healthy changes like losing weight and exercising more. Media stories about people who run marathons a year after surgery to bypass cholesterol-clogged arteries or who climb Mt. McKinley after being diagnosed with diabetes are interesting, but they don’t resonate with me. Mostly it’s because they often leave out the hard work needed to change and the backtracking that invariably accompanies it.
I ran across a truly inspiring story the other day in the American Journal of Health Promotion—one that shows how most of us ultimately manage to make changes that improve our lives. The journal’s founder and editor, Michael P. O’Donnell, wrote a moving essay about his father, Kevin O’Donnell. Once an overweight workaholic who smoked and drank heavily, ate mostly meat and potatoes, and didn’t exercise—and who eventually needed a double bypass—Kevin O’Donnell gradually made changes to improve his health. Now, at age 85, he has the cardiovascular system of a 65 year old and is working on a house-building project in North Korea.
How did Kevin O’Donnell engineer such a remarkable transformation? Read more »

Low-fat diets, move over. When it comes to lowering cholesterol, a “portfolio” diet that includes cholesterol-lowering foods such as oatmeal, nuts, and soy products is better.
Several years ago, researchers at St. Michael’s Hospital and the University of Toronto created what they called a “dietary portfolio of cholesterol-lowering foods.” It went after cholesterol by adding to a heart-healthy diet specific foods known to lower cholesterol: margarine enriched with plant sterols; oats, barley, psyllium, okra, and eggplant, all rich in soluble fiber; soy protein; and whole almonds.
In a head-to-head test against the low-fat diet traditionally recommended by the American Heart Association, the portfolio approach was the clear winner. (You can see the makeup of the test diet here.) After 24 weeks, it lowered harmful LDL cholesterol by 13%, while the low-fat diet lowered LDL by only 3%. As an added benefit, the portfolio approach also lowered triglycerides and blood pressure, and did not depress the level of beneficial HDL cholesterol. The results were published in the Journal of the American Medical Association.
What I appreciate about this study is that it Read more »
