Acknowledgements

We would like to thank all our second edition authors, especially the trainees at the John Radcliffe and St George’s hospitals. Additionally, we are very grateful to those who have gone the extra mile to ensure that our third edition chapters are up to date, especially Charlotte Bennett, Lucy MacKillop, and Jo Morrison who reviewed the highly specialized areas of neonatology, maternal medicine, and oncology to ensure that they contained the best available evidence. We would also like to thank the 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 overlap and repetition, some contributions have been considerably edited and we thank all our authors for their understanding. We are most grateful to Prof. Basky Thilaganathan for providing many of the ultrasound images and Ms Penny Trotter for the colposcopy pictures. Last, but definitely not least, we would like to thank our partners and families who continue to remain so patient and supportive throughout this project, especially Berni O’Connor ‘for doing all the real work on the home front’ and David Reynard ‘for putting up with all this’.
