Rheumatology is the sub-specialty in internal medicine that devoted to the diagnosis and therapy of rheumatic diseases. Rheumatologists mainly deal with clinical problems involving joints, soft tissues and allied conditions of connective tissues. Rheumatology is a rapidly evolving medical specialty; new scientific discoveries related to this specialty are largely related to better understanding of immunology of these disorders. Also, due to extended life span after development of medical technology, geriatric diseases are gaining attention with the growing importance of rheumatologic diseases. Consequently, our hospital established the division of Rheumatology in the department of internal medicine and East-West Arthritis/Rheumatology canter in 1999. Using radiology, musculoskeletal ultrasonography and approaches using nuclear medicine, we established ¡®one-stop system¡¯ for patients. We also developed cooperative treatment through the connection of new biologic agent/anti-rheumatic medication and traditional Korean medicine in order to put utmost efforts for the treatment of patients.
