Atlas of Rheumatoid Arthritis is a high-quality educational initiative, written by leaders in the field of rheumatology, containing a collection of approximately 150 relevant images, with extended descriptive captions and a comprehensive bibliography. The Atlas of Rheumatoid Arthritis will provide clinicians with a visual guide to rheumatoid arthritis, focusing on assessment, diagnosis and treatment, including newer research into the signalling pathways involved in the pathogenesis of RA, before focusing on the treatment of RA. Rheumatoid arthritis (RA) is the most common and most serious of the inflammatory arthritic disorders, and it dominates clinical rheumatological practice. Effective, early treatment is vital as this can slow the course of the disease and reduce joint damage. RA is usually treated using disease-modifying anti-rheumatic drugs (DMARDs), most commonly methotrexate. The newest treatments target the disease-causing immune elements specifically and directly.
