 • Reviewing the latest information for your own interest and lifelong learning


 About the authors:

 Dr. Stephen Ettinger is a household name in small animal medicine. He graduated from Cornell in 1964 and was one of the first veterinarians to specialize in cardiology, being a charter (founding) diplomate of the American College of Veterinary Internal Medicine in 1974. He has trained hundreds of students, general practitioners, and specialists. He is best known as the creator and editor of the Textbook of Veterinary Internal Medicine, the most highly respected veterinary resource for internal medical disorders of dogs and cats – the masterwork that gave rise to the factoids in this app.

 Dr. Ed Feldman is one of the great pioneers of small animal internal medicine and specifically of canine and feline endocrinology. His work on Cushing's disease, hyperparathyroidism, and several other commonly-recognized disorders have made him the benchmark for this specialty in veterinary medicine worldwide. He is the co-author of Canine and Feline Endocrinology (4 editions), co-editor of the Textbook of Veterinary Medicine for the past 5 editions (and this app) and of over 200 peer-reviewed scientific articles that have defined how veterinarians around the globe identify and treat endocrine diseases.

 Dr. Etienne Côté is a professor and cardiologist at the Atlantic Veterinary College, UPEI in Canada. He is best known for creating the Clinical Veterinary Advisor textbook, and for lectures that have garnered several teaching awards. He is the proud third co-editor of this edition of "Ettinger's" and of this app.
