Differentiating violent and nonviolent opiate-addicted reformatory inmates with the MMPI.

Used multivariate profile analysis and stepwise discriminant analysis in an effort to discriminate among four groups of male opiate-addicted reformatory inmates (N = 193) classified according to degree of criminal violence: (1) Bodily Violent (N = 19); (2) Potentially Bodily Violent (N = 25); (3) Materially Violent (N = 113); and (4) Nonviolent (N = 36). Profile analysis indicated that the four groups were very similar; a stepwise discriminant analysis significantly distinguished the Bodily Violent group from each of the other groups, but failed to differentiate successfully among the remaining three groups. A second stepwise discriminant analysis, in which Groups 2, 3 and 4 were combined, produced a significant discriminant function and correctly classified 68.4% of the Bodily Violent group and 75.9% of the combined Nonbodily Violent groups. The MMPI scales that contributed most to the latter prediction of group membership, in relative order of discriminating power, were: F, MA, D, PD, HS, PA and SI.

Major coagulopathy and "nonpoisonous" snake bites.

Two florid examples of disseminated coagulopathy following the bite of a rear-fanged snake (normally considered "nonvenomous") are reported. The posibility of clinically significant cases of snakebite envenomation due to "harmless" snakes in the United States is raised because of the diagnostic and therapeutic implications.
