Key Features * Features concise yet thorough description of the landmark studies and scientific breakthroughs coupled with easy-to-follow organizational structure of chapters that are accessible to readers at different levels of training. * Brings together world-leading experts to provide a fresh perspective to trainees such as residents and fellows-in-training, as well as more senior clinicians and researchers across the field of rheumatology and in specialties such as cardiology, dermatology, pulmonology, nephrology, and neurology, all of whom care for patients with rheumatologic conditions. * Allows the author to imagine and speculate about the evolution of this field in the coming decades. Examples of such speculative possibilities include use of synovial biopsy to predict response to treatment in rheumatoid arthritis, replacement of renal biopsy with urinary proteomics in diagnosing and classifying lupus nephritis, use of new therapeutics to obviate the need for steroids in the treatment of ANCA-associated vasculitis, use of machine learning to evaluate subtle changes in imaging in management of inflammatory arthritis, etc.
