This book discusses the epidemiology, etiopathogenesis, recurrence risk, and specific clinical and investigational evaluation of congenital malformations. With new material covering cancer, critical care, obesity and advanced maternal age, as well as practical advice on the most common conditions that present to those caring for pregnant women, this book will assist you in navigating the many risks of complications.
