Low-dose estrogen oral contraceptives may increase a woman's risk for chronic pelvic-pain symptoms and even pain during sexual climax, a new study suggests. Researchers at New York University and Waitemata District Health Board in Auckland, New Zealand, conducted a study to compare chronic pelvic-pain symptoms between young women who are current oral contraceptives users and non-users using data from an anonymous, Internet-based survey of women ages 18 to 39 within large university populations, reports UPI. The study found low-dose oral contraceptives users were more likely to report pelvic-pain symptoms and more likely to have chronic pelvic-pain symptoms than non-users.

Use of certain migraine drugs during pregnancy may lower IQ of baby, warns U.S. FDA

The U.S. Food and Drug Administration warned on the use of migraine drug valproate sodium in pregnant women as it could result in lower IQ scores in the baby. The FDA said the results of a recent study showed that children exposed to valproate products in the womb had lower IQs at the age of 6 than children who were exposed to other anti-epileptics. Drugs containing valproate are used to prevent migraine headaches, treat epileptic seizures and manic episodes associated with bipolar disorder. Abbott Laboratories' Depacon, Depakote, Depakote CP, Depakote ER and Depakene, and Noven Therapeutics LLC's Stavzor and their generics contain valproate, reports Reuters.

MS more common in black people than previously thought

For years doctors have assumed black people are less likely to develop multiple sclerosis (MS) than whites, but a new study suggests the opposite may be true. Researchers found black women were more likely than white women to be diagnosed with MS, in which the protective coating around nerve fibers breaks down, slowing signals travelling between the brain and body. Among men, there was no difference, reports Reuters.

Older, heavy smokers need CT screening for lung cancer, doctor group urges

Stepping into the debate over who should be screened for lung cancer, the American College of Chest Physicians issued new guidelines on Tuesday recommending that U.S. doctors offer annual low-dose CT (computed tomography) scanning to people whose age and smoking history puts them at significant risk of lung cancer. That means current smokers aged 55 to 74 with more than 30 pack-years of smoking, or former smokers with that profile who have quit within the last 15 years, reports Fox News.
