For those of you planning air travel to your next medical conference (and ACP Internist isn’t too shameless to plug Internal Medicine 2011 — we hope to see you there), TIME reports that there are five health risks that are rare yet have recently happened. Tips on avoiding these maladies include:
— E. Coli and MRSA on the tray table. Microbiologists found these two everywhere when they swabbed down flights. Bring your own disinfecting wipes.
— Bedbugs in the seat. British Airways fumigated two planes after a passenger posted pictures online about her experience. Wrap clothes in plastic and wash them.
— Sick seatmates. Everyone has experienced (or been) this person. Wash your hands.
— Deep vein thrombosis (DVT). Tennis star Serena Williams experienced a pulmonary embolism, possibly related to recent foot surgery. But DVT can happen to anyone restrained to a cramped position for long periods of time. Move around in-flight (but not during the beverage service, of course.)
— Dehydration. Dry cabin air may make it more difficult to fight off infections. Drink more water.

Lately I’ve been worrying about Kevin’s refusal to eat broccoli, and wondering what exactly is so good about those green bunches of roughage. In browsing the Web for more detailed information on the matter, I found a helpful vitamin chart.
The table comes from the HHS–sponsored National Women’s Health Information Center — a good spot to know of if you’re a woman looking online for reliable sources. It’s a bit simple for my taste. In the intro, we’re told there are 13 essential vitamins our bodies need. After some basics on Vitamin A — good for the eyes and skin, as you probably knew already — the chart picks up with a quick review of the essential B vitamins 1, 2 ,3 ,5 ,6 , 9 and 12 (my favorite), followed by a rundown on Vitamins C, D, E, H (that would be biotin) and K:
| Vitamins, Some of their Actions, and Good Food Sources |

- Helps blood flow
- Helps repair body tissues
|
Wheat germ oil, fortified cereals, egg yolk, beef liver, fish, milk, vegetable oils, nuts, fruits, peas, beans, broccoli, and spinach. |
| H (biotin) |

Alfalfa, spinach, cabbage, cheese, spinach, broccoli, brussels sprouts, kale, cabbage, tomatoes, plant oils. Your body usually makes all the vitamin K you need. |

Overall I’d say the chart is useful — a good place to start if you want to know, say, what’s a good, non-citrus source of Vitamin C. It could be improved by provision of more details, like the precise amount of Vitamin B2 per cupful of Swiss chard, and how preparing foods in distinct ways — like roasting, sautéing, boiling, or serving them raw — affects the nutritional value.

Teenagers and young adults who use marijuana may be messing with their heads in ways they don’t intend.
Evidence is mounting that regular marijuana use increases the chance that a teenager will develop psychosis, a pattern of unusual thoughts or perceptions, such as believing the television is transmitting secret messages. It also increases the risk of developing schizophrenia, a disabling brain disorder that not only causes psychosis, but also problems concentrating and loss of emotional expression.
In one recent study that followed nearly 2,000 teenagers as they became young adults, young people who smoked marijuana at least five times were twice as likely to have developed psychosis over the next 10 years as those who didn’t smoke pot.
Another new paper concluded that early marijuana use could actually hasten the onset of psychosis by three years. Those most at risk are youths who already have a mother, father, or sibling with schizophrenia or some other psychotic disorder.
Young people with a parent or sibling affected by psychosis have a roughly one in 10 chance of developing the condition themselves — even if they never smoke pot. Regular marijuana use, however, doubles their risk — to a one in five chance of becoming psychotic.
In comparison, youths in families unaffected by psychosis have a seven in 1,000 chance of developing it. If they smoke pot regularly, the risk doubles to 14 in 1,000. Read more »

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 »

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.
