Toxicologic Pathology - An Atlas

Over the past few decades, there has been an exponential growth of interest in the field of toxicologic pathology, a critical field in safety science, particularly as related to its impact on nonclinical safety in global drug development and care of the environment. Photomicrographic examples of selected nonproliferative and proliferative lesions are necessary to complement the written narratives in textbooks on toxicologic pathology. Toxicologic Pathology: An Atlas fits that need with input provided by top experts in the field. It will become a valuable reference, not only for toxicologic pathologists, but also for a wide variety of nonclinical safety scientists, especially in the pharmaceutical and biotech industries.
This book provides illustrations and descriptions of commonly observed findings in toxicologic pathology (i.e., over 1100 photomicrographic examples). These illustrations add visual context to the terms and descriptions commonly used in the field. The illustrations and accompanying descriptions were prepared and peer reviewed by editors and contributors who are known experts in toxicologic pathology, toxicology, and drug development. The Atlas is designed to be practical and easy to use and written with the hope that it will become a reliable "go-to" reference, and will be of interest to students and nonscientists (e.g., individuals serving on animal care and use committees) as a key, single source reference to understanding terminology and visualizing tissue changes described by toxicologic pathologists.

About the author

Dr. Pritam S. Sahota studied for his Veterinary Medicine (BVSc) and Veterinary Pathology (MVSc and PhD) degrees at Punjab Agricultural University in India (1976). He is a Diplomate of the American Board of Toxicology. After completing his PhD, he immigrated to the USA in 1976 and worked for Dawson Research Corporation in Orlando, Florida, for ten years (1976-86) with increasing responsibilities as Toxicologic Pathologist, Senior Toxicologic Pathologist, and Scientific Director. While working briefly for Dynamac Corporation in Research Triangle Park, North Carolina (1986-87), Dr. Sahota conducted retrospective scientific audits on 23 NTP carcinogenicity studies and participated in discussions with the representatives of NTP, FDA, and EPA to summarize the results of scientific audits of approximately 200 carcinogenicity studies. In 1987, Dr. Sahota joined Ciba-Geigy Pharmaceuticals in Summit, New Jersey, as Head/Manager of Pathologists and helped establish Pathology Peer Review, Scheduling, and Quality Control systems. He continued to work primarily in this position with increasing responsibilities in Ciba-Geigy and then Novartis Pharmaceuticals (resulting from the Ciba/Sandoz merger in 1997) up to 2000, when he became Head of Pathology (Director¿ Executive Director: 2000-12, East Hanover, NJ). In addition to his pathology responsibilities, Dr. Sahota also served as International Project Team Representative for several marketed drugs, including an antihypertensive blockbuster, Diovan, where he successfully defended the company's position with the FDA and various International Regulatory Authorities. During 2010-12, he successfully led the following Global Preclinical Safety initiatives at Novartis: Patient Centricity, Cardiotoxicity, Ocular Toxicity, and evaluation of rodent carcinogenicity potential based on short-term toxicity and genotoxicity studies to minimize delays in regulatory submissions. Dr. Sahota also held an adjunct academic appointment as an Assistant Professor in the University of Medicine and Dentistry of New Jersey, Newark, New Jersey, for approximately eight years. In 2013 and 2018, he co-edited as Lead Editor the First and Second Editions of the book entitled "Toxicologic Pathology, Nonclinical Safety Assessment" (CRC Press). In 2019, Dr. Sahota co-edited as Lead Editor "The Illustrated Dictionary of Toxicologic Pathology and Safety Science" (CRC Press), which was considered one of the 100 Best Pharmaceutical Books of All Time (Book Authority). Finally, Dr. Sahota, as Lead Editor, published Current Topics in Nonclinical Drug Development Volume-1 (2020) and Road to Greatness (2022).
