Scanning electron microscopy: application in the identification of diatoms in cases of drowning.

A simple and rapid method is described for processing organ and water samples for the identification of diatoms so that they can be studied and recorded for taxonomic and diagnostic purposes. Samples are treated with concentrated nitric acid; the fluid obtained is centrifuged, and its sediment is dried, coated, and examined under the scanning electron microscope. The method does not alter the morphology of diatoms and allows the study of freshwater and seawater species present in the organs of bodies found in the water, making possible the diagnosis of drowning under specific conditions.

Antisocial burnout: an exploratory study

The more flagrant aspects of Antisocial Personality Disorder (APD), particularly criminality, are thought to diminish or "burnout" after age 30. However, empirical evidence of burnout in clinically defined groups is lacking. This study explores burnout in a cohort of forensic psychiatric patients, aged 41 to 67, with clinically diagnosed DSM-III APD (N = 39). Conviction data revealed that criminality did appear to decline from age 27 onward, but not in a straightforward manner. Further, a significant portion of the cohort remained criminally active throughout most of their adult lives. Age did not appear to interact with crime class.
