Differential diagnosis of chronic monoarthritis in chidren

Results There was two age more frequently 2 and 11 years (R: 0.10-14.4) .41 fem,27masc. The most commont joints involved were:52 knee (88%),5 ankle, 1 elbow and 1 finger. 24(40.6%) patients had JCA, 13 fem 11 masc, the evolution was: 10 pauciarticular, 5 polyarticular 3 Spondyloarthropathies, 6 others. The men age of JAC was 7 years (r:6m-14a). Ocular examination: 1 blefaritis, 1 corneal erosions,1 acute iridiociclitis. Joint fluid: 90% inflammatory. Arthroscopic with patology anatomic: 11 nonspecific chronic synovitis. Another diagnosis were: 5 body forein (pine needle, sliver, toothpick), 6 discoid meniscus, 3 synovial chondromatosis, 2 distention ligament, 2 osteochondritis, 2 synovial cyst, 1 Synovial haemangioma, 1 Pigmented villo-nodular synovitis, 1 patient with agamaglobulinemia (Brutton Disease), 1 Tenosinovitis in Celiac disease. The laboratory tests include antinuclear antibody and ocular examination were non significative to diferenciate ACJ to another crhronic monoarthritis (Fisher exact test, p> 0.27). On the other hand highly significant association between patients with ACJ and cronic synovitis (X p>0.3005) was found.
