Written by medical specialists and faculty of the Department of Obstetricians and Gynaecology, National University Health Services, Integrated Approach to Obstetrics and Gynaecology is a textbook for medical undergraduates and residents.This textbook is unique in that it takes an integrated approach in discussing the six phases in the life of a woman, namely, the early years of growing up, the reproductive years, pre-conception, early pregnancy, pregnancy care, and functional ageing in a mature woman.Emphasis has been focused on information that constitutes essential "core knowledge" in the blueprint of the medical undergraduate curriculum. The format is easy to follow: background introduction to history; examinations and investigations to establish a diagnosis and then treatment and management. However, this may have to be modified as deemed appropriate for a particular topic. Where appropriate, knowledge that is "good to know" has been incorporated beyond the essential "core knowledge."
