T-cell activity, thereby terminating the inflammation of the central nervous system [75]. Moreover, corticoids may reduce allergen specific T-cells through apoptosis, which is one of the mechanisms of effectiveness of corticoids in asthmatics [76], as well as induce apoptosis of endomysial T-cells in human idiopathic polymyositis, thus modifying the inflammation [77]. Interestingly, the expression of Bcl-2 may be an important factor in protecting the lymphocytes in inflamed synovial membranes from glucocorticoid-induced apoptosis [78].

Similar to the situation in adult rheumatoid arthritis, US has proved to be more sensitive than radiography or clinical examination in the detection of joint effusion and synovial hypertrophy in these patients (Sureda et al. 1994 Lamer and Sebag 2000 El-Miedany et al. 2001). In the knee of children with monoarticular or paudarticular juvenile idiopathic arthritis, quantitative assessment of...
