Autoimmunity and the Thyroid is a collection of papers presented at an International Satellite Meeting prior to the 7th International Congress of Endocrinology, held at the Mount Sinai Hospital, University of Toronto Medical School on June 29 and 30, 1984. The book provides presentations of participants relating to selected aspects of immune regulation and its role in autoimmune thyroid diseases. Concepts on humoral and cell-mediated immunity mechanisms in the pathogenesis of autoimmune thyroid disease are reviewed; important observations with promising clinical implications in terms of immunogenetics of Graves' and Hashimoto's diseases are presented; and selection of appropriate therapy for Graves' thyrotoxicosis, and the possibility of preventive immunosuppressive and ophthalmopathy therapy are discussed. Endocrinologists, physicians, pathologists, physiologists, and medical researchers will find the book interesting.
