A new form of muscular dystrophy identified
Mayo Clinic researchers have identified a previously unknown form of muscular dystrophy, a group of genetic diseases characterized by progressive weakness and muscle degeneration. This newly identified form develops after age 40 and causes heart muscle damage, limb muscle weakness and nerve damage. The researchers have named the newly defined disorder "zaspopathy" (Zas-PO-path-ee).  more

Report assesses health implications of perchlorate ingestion
A new report by the National Academies' National Research Council on the health effects of perchlorate, a chemical that in high doses can decrease thyroid function in humans and that is present in many public drinking-water supplies, says daily ingestion of up to 0.0007 milligrams per kilogram of body weight can occur without adversely affecting the health of even the most sensitive populations. That amount is more than 20 times the "reference dose" proposed by the U.S. Environmental Protection Agency in a recent draft risk assessment.  more

Potentially harmful fluoride levels found in some instant teas

An observational study of 6,250 patients enrolled in the Maryland Medicaid program found that COX-2 inhibitors did not increase the risk for cardiovascular events over nonnaproxen NSAIDs in a high-risk population. more

Patients taking warfarin along with NSAIDs or COX-2 inhibitors have increased risk of upper gastrointentinal hemorrhage
