This book builds upon the first edition with new and improved chapters. The book explores the rich assemblage of clinical wisdom from expert rheumatologists from a wide range of specialties including Vasculitis and Sjogren’s syndrome. It examines the nuggets or ‘pearls’ of wisdom gained from collective clinical experience about the diagnosis or treatment of various diseases whilst also aiming to debunk myths that have influenced the practice of rheumatology by many clinicians.
