For health professionals who are asked by women and their families to provide answers on potential reproductive effects of xenobiotics and radiation, this volume presents the approaches and clinical tools developed by the multidisciplinary team at the Motherisk Clinic in Toronto to inform, counsel, and follow up pregnant women exposed to drugs, chemicals, or radiation in pregnancy. This revised and expanded edition adds several novel aspects, such as the maternal-fetal toxicology of medicinal plants, developmental risk assessment, and biological markers of intrauterine exposure to drugs of abuse. This edition also includes clinical cases at the beginning of most chapters, with answers at the end. Annotation c. by Book News, Inc., Portland, Or.
