...nature, and a new study showed that this acid can cause cavities in healthy tooth enamel. Fortunately, fluoride counteracts the problem, so make sure your children brush their teeth after swallowing cough syrup. Also try giving the medication with meals, when the body's natural production of saliva helps protect the teeth...
...fields and ponds--which had a disastrous effect on wildlife--the WHO is focusing this time on spraying DDT on the inside walls of homes once or twice a year in malaria-prone areas. Why? DDT is particularly effective at repelling and not just killing mosquitoes, which helps protect enclosed spaces. Environmental organizations aren't thrilled by the idea, but two of the largest have endorsed limited spraying, figuring that some risk to the environment is justified to save human lives...
People seeking the heart-protective powers of omega-3 fatty acids in fish have been warned about the mercury, dioxins and PCBs that they might be consuming with their meal. But a study from the Harvard School of Public Health showed that while those contaminants pose a danger, particularly for women of childbearing age, for most people the benefits of fish outweigh the risks. Eat modest servings of fish each week--particularly salmon and bluefish--and you may reduce your risk of coronary heart disease 36%. Elsewhere, researchers at Louisiana State University reported that omega-3s can help protect cells...
Science fought back against avian flu with a successful test of a new vaccine. In a study of 451 subjects, the preparation caused no significant side effects and produced antibodies at a level that is usually sufficient to protect against common strains of flu--a good sign that it will work against the avian variety too. It's the common strains, of course, that ought to cause us concern, since avian flu has yet to kill anybody in the U.S. and the common flu kills 36,000 each year. Girding for this winter's assault, the Food and Drug Administration...
Statins have earned a reputation lately as a wonder drug. Not only do they protect against heart disease by controlling the amount of cholesterol the liver churns out, but they can also dampen the inflammatory flare-ups that contribute to everything from arthritis to heart attacks. Early studies even hint that statins may also work on the plaques and tangles that cause Alzheimer's disease. But all drugs have their limits. An analysis of 12 trials found that patients who had taken statins within two weeks of having a heart attack or angina did not reduce their risk of dying...
