People with a rare, genetic condition that causes skin cancer usually studiously avoid sunlight in order to reduce their cancer risk. But, in doing so, these people increase their risk of vitamin D deficiency, researchers reported Monday. Basal cell nevus syndrome causes people to develop basal cell cancer lesions as early as adolescence. But in a study of 41 people with the condition, more than half were found to be deficient in vitamin D. Vitamin D is synthesized in the skin from exposure to sunlight.

It's what Dr. Jean Romagnoli doesn't know about the health of the 33 trapped miners that worries him. As chief medical officer of the team rescuing the miners stuck underground since Aug. 5, Romagnoli has been monitoring their health and preparing for their reentry to life above ground, which could happen as early as Wednesday. Once rescued, they will receive immediate attention at a makeshift clinic near the mine entrance and then two days of treatment at a hospital in nearby Copiapo.

Frank C. Garland, the UC San Diego epidemiologist who, with his brother Cedric, was the first to demonstrate that vitamin D deficiencies play a role in cancer and other diseases, died Aug. 17 at UCSD Thornton Hospital. He was 60 and had been suffering for nearly a year from cancer of the esophageal junction. "Over the past three decades, the Garlands' seminal hypothesis has been largely confirmed by numerous additional studies," Dr. Edward Giovannucci of the Harvard School of Public Health said in a statement.

For more than 20 years, I was plagued with dry, flaky skin on the side of my nose and behind my earlobes. I went to several doctors, including dermatologists. We tried various salves, to no avail. I wondered if this ailment was caused by a fungus. As a chemist, I know that iodine is very effective on fungus. I applied tincture of iodine with my fingers (every two days for a week) and got cured within a week. It's been two months, and the spots have not returned. I previously had success treating toenail fungus with iodine.

Raising the amount of vitamin D in the blood appears to help some people -- at least those deficient in the vitamin -- reduce their risk of heart disease by about 30%, researchers announced Monday. The findings, though preliminary, support further investigation of the interplay between vitamin D and heart health. Observational studies have linked heart disease with low vitamin D levels in the blood. In recent years, studies have shown that as many as three-quarters of Americans have a concentration in their blood that is under the normal level of 30 nanograms per milliliter.

I am 62 years old and just had my second bone-density test. I was told I have osteopenia and should take Boniva. I have been lactose-intolerant, so I avoid dairy products. I have tried calcium, but it makes me constipated. I took Actonel but developed leg cramps. I took one Boniva tablet the nurse gave me as a sample, but I now have unbearable indigestion. Is there anything natural I can take? Osteopenia is a controversial condition. The concept of pre-osteoporosis was created somewhat arbitrarily in 1992 for research purposes rather than to guide treatment.

Clippers center Chris Kaman had too much energy to sleep. But he didn't have enough energy to stay active and avoid lying around at home watching his DVD collection. Kaman had enough energy to remain on the team's active roster. But he didn't have enough energy to replicate the string of seven consecutive games earlier this season in which he scored at least 20 points. Kaman missed practice Nov. 12, but it wasn't until two weeks ago during a doctor's visit when he discovered why he felt listless: doctors diagnosed he was deficient in Vitamin D, which increases the flow of calcium into the bloodstream and helps prevent bones from becoming brittle.

It's not hard to get all of your daily needs from nonmeat sources, nutritionists say, but it takes thought and planning -- plus a few tricks. No matter how old your vegetarian kids are, the first step is to educate yourself on healthful alternatives to animal products, such as hummus, tofu, quinoa and legumes. When vegetarian teens live in a meat-eating family, they should also take some of the responsibility for preparing vegetarian meals, says nutritionist and epidemiologist Dianne Neumark-Sztainer, of the University of Minnesota, Twin Cities, so that the entire burden doesn't fall on parents.

At least 1 in 5 U.S. children aged 1 to 11 don't get enough vitamin D and could be at risk for a variety of health problems including weak bones, a national analysis suggests. By a looser measure, almost 90% of black children that age and 80% of Latino kids could be vitamin D deficient -- "astounding numbers" that should serve as a call to action, said Dr. Jonathan Mansbach, lead author of the analysis and a researcher at Harvard Medical School and Children's Hospital Boston. The analysis was released online today by the journal Pediatrics.

You have said that people who get 10 to 15 minutes of sun exposure at one time can make enough vitamin D in their skin. On what percent of the body is it necessary to get that exposure in order to convert the sun into 10,000 IUs per day? Just the face? The hands? Bare naked? The exact amount of sun exposure needed varies according to the time of day, season of the year, latitude and color of the individual's skin. (Darker skin needs more time in the sun to make the same amount of vitamin D.)
