Exposure to rapid succession disasters: a study of residents at the epicenter of the Chilean Bío Bío earthquake.

We examined cumulative and specific types of trauma exposure as predictors of distress and impairment following a multifaceted community disaster. Approximately 3 months after the 8.8 magnitude earthquake, tsunami, and subsequent looting in Bío Bío, Chile, face-to-face interviews were conducted in 5 provinces closest to the epicenter.

Comparison of the Efficacy and Tolerability of Dexketoprofen and Ketoprofen in the Treatment of Primary Dysmenorrhea.

Dexketoprofen, the pure S(+)-enantiomer of ketoprofen, is a promising new analgesic, but few clinical trials have yet examined its efficacy and tolerability. In this study, patients with a history of primary dysmenorrhea were treated with dexketoprofen doses of 12.5 and 25 mg, ketoprofen 50 mg, and placebo using a randomized, four-way crossover design.
