Role of dorsal scapular nerve entrapment in unilateral interscapular pain.

Objective: To determine the contribution of dorsal scapular nerve (DSN) entrapment to interscapular pain.

Design: A descriptive research study.

Setting: Institutional practice.

Evaluation of apoptosis induction in human peripheral blood mononuclear cells and synovial cells in patients with rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory destructive disease involving the joint and characterized by T-lymphocyte accumulation within the synovial compartment. It is dominated by the presence of macrophages, plasma cells and synovial fibroblasts which are the main pathogenic factors leading to the destruction of bone and cartilage. The survival of these cells may be promoted by inadequate apoptosis leading to synovial hyperplasia.
