Written by known authors with established expertise in their respective fields, under the guidance of Professor John Wass, Professor Wiebke Arlt, and Dr Robert Semple (Editors), the Oxford Textbook of Endocrinology and Diabetes, now in it’s third edition, offers a comprehensive picture of endocrine and diabetes-related disorders. The book covers a variety of topics, from general principles of basic and clinical endocrinology to current guideline recommendations concerning clinical practice. The textbook is intended to be a reference work for both trainees and specialists looking to acquire or develop knowledge in the fields of endocrinology and diabetes. The wide scope of the manuscript encompasses chapters on the management of individual endocrine disorders, diabetes, metabolism, but also larger field topics, such as the “Endocrinology of Cancer” and “Endocrine Responses to Systemic Diseases and Substance Use”. The book also includes new chapters on “Endocrinology of Pregnancy” and “Management of the Transgender Patient”. Focusing on wide-ranging topics related to pediatric and reproductive endocrinology and hormone dysfunctions in systemic illness and cancer, HIV infection, anorexia nervosa, drug and alcoholic abuse, the manuscript also provides a useful reference for specialists in the fields of pediatrics, obstetrics and gynecology, surgery, psychiatry and internal medicine. This edition has been revised to provide up-to-date information concerning recommended diagnostic approaches according to current guidelines and to reflect recent advances in available therapies. Designed in the established Oxford Textbook style, the manuscript pairs clearly written text with informative illustrations, tables and text-boxes, to provide a user-friendly, easy-to-read guidebook. Purchase of the print edition is accompanied by the complimentary full online version which allows for easy access to up-to-date recommendations whenever needed, whether during clinical practice, bedside patient care or while travelling.
