Foreword

I have had the privilege, following graduation from veterinary school, of completing an internship, a three-year residency, several years in private practice, joining my first veterinary school faculty at the Western College of Veterinary Medicine in Saskatoon and then, for the past 35+ years, on faculty at the University of California, Davis. The absolute high point of my career, of any decade, year, month or day would certainly be having the opportunity to participate in ‘rounds.' Sitting around a table or on the floor of a hospital ward, reviewing the presenting complaint and history, physical examination, laboratory and imaging studies … trying to figure out the cause for an abnormality in a cat or dog … these were the greatest of challenges, and they were consistently stressful, exciting and fun! Rounds were always a wonderful complement to my seeing cases, because they offered a place to share observations and thought processes with colleagues, to learn how they may have done or thought differently. Always a learning experience. However, it must be admitted, I always entered rounds with fear, honestly two fears: first, that my ignorance would be revealed; and/or second, that the rounds I was conducting would be boring. So, I always tried to determine ahead of time the case or cases to be presented – whether as a student or an intern – when I was going to be presenting a case and asked questions, or as a faculty member attempting to take advantage of a ‘teaching opportunity.' As a person who was often a ‘leader' in rounds (usually defined as being the oldest person in the room), it seemed that I was always expected to know the answer to any question asked, while having to shoulder the responsibility for making rounds interesting, logical, and practical. Quickly reviewing a subject prior to rounds or before any case discussion always added to my sense of confidence and competence.

The Blackwell Five-Minute Veterinary Consult's Clinical Companion; Small Animal Endocrinology and Reproduction will serve as a wonderful aid to those who may be preparing for rounds, for those concerned that their differential diagnosis is incomplete, or that their chosen strategy in managing a newly diagnosed condition may not be up-to-date, or for those preparing to meet and discuss one of these conditions with an owner, student, colleague, or teacher.

Among the many students with whom I had the honor and pleasure to share time on my internal medicine service were Deborah Greco and Autumn Davidson. Teachers love to impart their knowledge to their students. A few students absorb that knowledge and then dedicate their careers to build from that foundation while also teaching the next generation of ‘students.' This should always be viewed as a wonderful compliment to their teachers. Doctors Greco and Davidson have evolved to become world-renowned and respected small animal endocrine and reproduction experts. As one of their early instructors, I take great pride in their successes. Deb Greco and Autumn Davidson are to be congratulated on assembling a thorough list of topics relative to canine and feline endocrinology and reproduction, with more than 60 chapter titles that encompass a huge number of conditions and biochemical abnormalities encountered in small animal practice. Most importantly, the authors who were assembled to carry out the task of presenting each subject are among the world's best veterinary clinicians and clinical researchers. These individuals bring vast experience and a wealth of knowledge to their assignments. Each subject is succinctly reviewed practically and logically, while being cost-effective. When appropriate, discussions begin with typical client concerns, history and physical examination features, diagnostic approaches, therapeutic strategies, and prognosis.

This Clinical Companion should be on the bookshelf of every small animal veterinary hospital. The information it provides can be easily applied to the clinical diagnosis and treatment of endocrine or reproductive disorders for the benefit of the patient, owner, veterinarian and the entire veterinary health team.

Enjoy!

Preface

As internal medicine consultants, Dr Davidson and I observed the need for a readily accessible, concise reference on endocrinology and reproduction for the busy veterinary practitioner. This book was developed as an expanded companion book to the Five-Minute Veterinary Consult, but also serves as a bridge to more comprehensive texts such as Canine and Feline Endocrinology and Reproduction by Feldman and Nelson. We would like to thank our contributors for sharing their expertise. We look forward to providing veterinary practitioners with another tool to manage challenging reproductive and endocrine cases. Thank you Dr Davidson for your friendship, unwavering support and hard work – all of which made this book possible.

Deborah S. Greco DVM, PhD, DACVIM (Internal Medicine)

I credit Dr Greco for first coming up with the idea of a comprehensive but concise reference text covering clinical conditions in small animal endocrinology and reproduction. She did not have to work hard to convince me that this would be a welcome addition to the library of small animal clinicians. Veterinarians in clinical practice – both generalists and specialists – are always pressed for time, but are also committed to providing the best care for their patients and the most current information to their clients. Excellent textbooks of endocrinology and reproduction already exist; their comprehensiveness begat lengthiness, and are difficult to peruse in 10 minutes between cases. Our thought was to create a reference text covering all of the topics we thought were relevant to the practice of endocrinology and reproduction, in a format that could be read in 5 minutes (well, maybe 10 minutes), yet permitted the reader to gain excellent knowledge of the topic (or to confirm their knowledge already in place). The list of topics grew alarmingly, but our list of knowledgeable and willing authors made it all seem possible. Voila! Blackwell's Five-Minute Veterinary Consult Clinical Companion Small Animal Endocrinology and Reproduction! Thank you Dr Greco, thank you to all our contributing authors for time spent preparing manuscripts in their already overly busy lives, and finally, thank you Tom (my loving husband) for patiently waiting for me to finish working on the computer every night.
