Severe form of "enlarged prostate" discovered

Millions of middle-aged and older men experience the symptoms of an enlarged prostate multiple times during the day and night. What they may not know is that the disease known as BPH (benign prostatic hyperplasia), marked by urgency and frequent urination, is not one but at least a pair of disorders, and that one of the pair - tied to a newly identified gene - has far more serious implications.

Studies on heart disease do not provide sex-based analysis

Heart disease differences in men and women continue to be poorly understood because women are included in clinical trials far less than men, and even when women are included, study results are not reported by sex, according to a study in the current issue of Mayo Clinic Proceedings.
