DNA analysis of abortion material assisted by histology screening.

In cases of rape leading to fertilization, paternity testing can retrospectively identify the assailant. Abortion material commonly represents a mixture of maternal and fetal tissue and blood, which cannot be differentiated with the naked eye. Consequently, DNA typing of abortion material may be complicated, including band overlap if maternal tissue predominates. Therefore, histology screening of the abortion content for typical fetal tissue components, such as chorionic villi, followed by selected DNA typing of this sample is suggested. This combined approach is illustrated by a selected case demonstrating the reliability and concurrence of the histology and genetic results.     

Heimlich trauma: a violent maneuver.

The Heimlich maneuver is a life-saving technique for dislodging foreign material from the respiratory tract. This report illustrates intraabdominal injuries, including a large mesenteric laceration, mesenteric contusions, and intraperitoneal hemorrhage, that occurred in a recipient of a vigorously applied Heimlich maneuver. The potential for confusing such injuries with homicidally inflicted injuries is emphasized.     

Problematic police performance and the personality assessment inventory

A relative newcomer to personality assessment in the area of law enforcement is the Personality Assessment Inventory, or PAI. Earlier MMPI research in the area of police selection has focused upon antisocial behavior, control of aggression, and validity indices, particularly the L scale. In this study T scores for 800 male and female police officer candidates on the PAI scales Negative Impression (NIM), Positive Impression (PIM), Antisocial-Antisocial Behaviors (ANTA), Antisocial-Egocentricity (ANTE), and Antisocial-Stimulus Seeking (ANTS) were used as predictors of the criterion variables Insubordination, Excessive Citizen Complaints, and Neglect of Duty. Highly significant coefficients were obtained for ANTE as a predictor of Insubordination and Excessive Citizen Complaints. For Neglect of Duty, two significant coefficients were obtained, one for ANTS and another for NIM. Discussion centered on the fact that egocentricity is a predictor of Insubordination and Excessive Citizen Complaints, and Neglect of Duty is related to stimulus seeking. Authors' Note: William U.
