Abstract:
It is supposed that autoaggressive T cell activation, triggered by unknown microorganisms, initiates inflammation in rheumatoid arthritis. It leads to activation of macrophages and synovial fibroblasts in the synovial tissues, which form a granulomatous pannus tissue. It becomes a platform of joint destruction activating osteoclastogenesis and release of cartilage-degrading enzymes. Biological reagents recently brought into the clinics are potently anti-rheumatic, and, in some cases, stop progression of the joint destruction and even repair the joint. It is now a realistic goal for next-generation anti-rheumatic treatments to inhibit joint destruction completely.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
