Abstract

The usefulness of monozygotic (MZ) twins for studying the efficacy of different face lift techniques is described. The data suggest that no particular procedure out of four under consideration is superior to any other. Next, reviews of recent twin studies of congenital anomalies, personality traits and coital orgasmic infrequency, and physical activity participation are presented. Finally, timely topics of public interest are also described. They include a rare birth consequence of artificial reproductive technology, an update on state legislation regarding parents' rights to decide the classroom placement of their young twins, and medical malpractice lawsuits involving premature twins.
