Angel dust: possible effects on the fetus.

A case report of an infant whose mother used phencyclidine (PCP, "angel dust") during pregnancy is presented. As a neonate, the infant showed abnormal behavior and an unusual appearance, and later, spastic quadriparesis. Based on previous animal studies, it is likely that this infant had prolonged exposure to PCP as a fetus. His abnormal neonatal behavior was consistent with previously reported effects of this drug. The relationship between his exposure to PCP and his dysmorphology and spasticity remains speculative. It is suggested that clinicians be alert to further cases of these associations.
