First published in 1919 under the title "Diseases of Women", "Gynaecology by Ten Teachers" has become a world-renowned textbook in its field. The eighteenth edition of this classic book is thoroughly updated in line with the new curriculum, integrating clinical material and incorporating the latest advances in gynaecology. The book also retains its comprehensive coverage of the subject area, and the much-loved textual features of previous editions. Each chapter is highly structured, with an overview, definition, prevalence, aetiology, clinical features, differential diagnosis, investigations, treatment, key points, new developments, and references where appropriate. With a new editor and a new team of contributing authors, the eighteenth edition combines authoritative detail with a clear guide to essential knowledge. Both Gynaecology and Obstetrics volumes are carefully edited to ensure consistency of structure, style and level of detail, and to avoid overlap of material. This book owes a great debt to Professor Stuart Campbell who, along with the present editor Ash Monga, was responsible for introducing the concepts and features to the seventeenth edition that are continued here.
