Vasculitides are a heterogeneous group of disorders epitomized by vascular inflammation so severe that it can result in multiple organ failure and even death if unrecognized and therefore untreated. With the recognition that vasculitides affect populations of patients around the world and in every nationality and walk of life, from childhood to older age, there is a demand for clear, concise and reliable information regarding the epidemiology, pathogenesis, clinical presentation, laboratory evaluation and management of these disorders. The Vasculitides, edited by David S. Younger MD, Associated Clinical Professor of Neurology and Public Health at the New York University School of Medicine, combines experts in the medical fields from North America and diverse European nations into a single book. Derived from the 16th International Vasculitis and ANCA Workshop, the book is endorsed by organizers of the United Kingdom and Ireland Vasculitis Societies where it will make its official professional debut. This two-volume book, encyclopedic in content, is presented in a two-volume set equally divided into General Considerations and Systemic Vasculitides, followed by Vasculitis of the Nervous System, Treatment, and an Epilogue containing a tribute to Loic Guillevin, Past-President of the International Vasculitis and ANCA Workshop. It is anticipated that physicians and researchers in all specialties and pediatricians and internists alike who consider vasculitis in their work will find this book to be an invaluable asset.
