Illicit opiat use during methadone maintenance.
The core hypothesis deduced from the Dole-Nyswander blockade formulation is that methadone is a sufficient but not necessary condition for abstinence from heroin. It is argued that this hypothesis has not been tested with scientifically adequate research. A research design is suggested. Since the Dole-Nyswander focus is at the physiological and metabolic level, it is argued that the blockade theory, pending, its scientific validation, should be supplemented by sociological, organizational, and economic theory.

Hernias involving the pericardial cavity are rare. The author describes such a case involving an 85-year-old man who was asymptomatic except for right-upper-quadrant pain. The radiological appearance consisted of loops of bowel lying beside the heart.
