This concise and practical reference, tailored for fellows, residents, and medical students rotating on rheumatology subspecialty services, covers both inpatient and outpatient management of rheumatology with the same clinical practicality as the widely popular Washington Manual™ of Medical Therapeutics. This manual also serves as a pocket reference for medical professionals specializing in rheumatology. It is the result of a collaborative effort of residents, fellows, and clinical faculty from the distinguished Washington University School of Medicine and focuses on how to approach rheumatologic problems. It provides guidance on how to perform the musculoskeletal exam and arthrocentesis, what laboratory testing may prove useful, and which medications are appropriate , including dosages and recommended monitoring, all framed within a brief overview of the major rheumatologic diseases.
