This splendid volume presents numerous aspects of preterm labor and delivery, from its fundamental mechanism to clinically focused approaches.

The rates of overall survival and intact survival of the premature infants are also excellent in Japan. Thus Japan?s approach to preterm labor and delivery has long attracted attention. In each chapter, experts describe specific issues unique to conditions in Japan, including diagnosis, tocolytic agents, definition of clinical chorioamnionitis, treatment of bacterial vaginosis, role of amniocentesis, management of preterm premature membrane rupture and also placental pathology, presenting definitive evidence of the reduced incidence of preterm delivery in Japan.
