In an attempt to curb excessive drinking on college campuses, many universities have turned to "social norms" marketing campaigns. Despite widespread acceptance among health educators, empirical results are clouded by measurement problems. This study, based on a random sample of 550 students, examined the effects of misperceptions of friends' and typical college students' drinking on one's drinking behavior. Results indicate that drinking behavior is positively related to perceptions of friends' drinking as suggested by the theory of planned behavior, which emphasizes subjective as opposed to social norms.

This article reports a death occurring in an apparently healthy, 27-year-old male as a consequence of an adverse reaction to a common urinary tract antibiotic (nalidixic acid). The deceased had cardiac enlargement at autopsy. The clinical presentation before his sudden death coincides with the occurrence of seizures and psychotic reaction as an adverse reaction to the injection of the drug, rather than merely a result of cardiac symptoms.

The following case report describes an accidental stabbing that occurred on Halloween. The unwitting victim, while preparing for a holiday charade, stabbed himself with an ornamental dagger. By placing himself in a potentially hazardous situation, the victim's behavior entailed risk taking. The psychological implications of such risk taking are complex, and may be compared to such behaviors as russian roulette, gambling, and parasuicide.
