viPrefaceWelcome to the third edition of this Oxford Handbook. In obstetrics andgynaecology, as in all ﬁelds of medicine, the available evidence, technologyand guidelines can move forward at a rapid pace and often prove difﬁcultto keep up with. As the majority of junior doctors are well aware, thegaps in our knowledge often become apparent at the most inopportunemoments; this book seeks to ﬁll those gaps rapidly and effectively. It usesthe well-known Oxford Handbook format to facilitate easy navigationaround concise, clinically relevant, evidence-based information. It can bequickly dipped into for speciﬁc answers between seeing patients in clinic oron delivery suite, as well as providing a solid, general grounding for thosejust beginning in the specialty. It also has sufﬁcient depth and detail to provide a good starting point in the preparation for postgraduate exams. Toensure the most up-to-date information is always available, emphasis hasbeen placed on providing relevant web addresses, especially for guidelinesand useful organizations. Text boxes have also been employed to helphighlight some of the more important pieces of information.Although this handbook is most likely to be used by trainees within thespecialty, we envisage it will be useful for all those involved in women’shealth, including GPs, midwives, and medical students. We hope you ﬁnd ita helpful resource and that it proves to be a valuable companion and guidein your everyday practice of obstetrics and gynaecology.
viiAcknowledgementsWe would like to thank all our second edition authors, especially thetrainees at the John Radcliffe and St George’s hospitals. Additionally, weare very grateful to those who have gone the extra mile to ensure thatour third edition chapters are up to date, especially Charlotte Bennett,Lucy MacKillop, and Jo Morrison who reviewed the highly specializedareas of neonatology, maternal medicine, and oncology to ensure thatthey contained the best available evidence. We would also like to thankthe doctors of all grades who anonymously reviewed some of the text,providing valuable feedback and further ﬁne-tuning the ﬁnished manuscript. To conform to the Oxford Handbook style and to avoid overlapand repetition, some contributions have been considerably edited and wethank all our authors for their understanding. We are most grateful toProf. Basky Thilaganathan for providing many of the ultrasound imagesand Ms Penny Trotter for the colposcopy pictures. Last, but deﬁnitelynot least, we would like to thank our partners and families who continueto remain so patient and supportive throughout this project, especiallyBerni O’Connor ‘for doing all the real work on the home front’ and DavidReynard ‘for putting up with all this’.Sally Collins, Sabaratnam Arulkumaran,Kevin Hayes, Simon Jackson, and Lawrence ImpeyLondon and Oxford, October 2012
