Rheumatology is the study and practice of medical immunology which is concerned with the management of rheumatic diseases. More than 200 different disorders fall under rheumatic diseases. These include rheumatoid arthritis, gout, lupus, osteoporosis, osteoarthritis, back pain and tendinits, besides others. Many of these conditions are degenerative and in some cases, fatal. The field of rheumatology is evidence-driven and new treatment modalities are being explored. Most rheumatic diseases are managed with a prescription of NSAIDs, analgesics, disease-modifying anti-rheumatic drugs, monoclonal antibodies and steroids. Physiotherapy and occupational therapy offer innovative solutions to the management of these disorders and improvement of the quality of life. A major research direction in rheumatology is the understanding of the role of autoimmunity in rheumatic diseases, and the association of the immune system with joints and bones. The objective of this book is to give a general view of the different areas of rheumatology and rheumatological disorders. The various studies that are constantly contributing towards evolution of this field are examined in detail. It includes contributions of experts and scientists which will provide innovative insights into rheumatology.
