Serum S100A12 and temporomandibular joint magnetic resonance imaging in juvenile idiopathic arthritis Egyptian patients: a case control study.

This study aimed to measure serum levels of the proinflammatory protein S100A12, investigate clinical as well as contrast enhanced magnetic resonance imaging findings of temporomandibular joint inflammation among juvenile idiopathic arthritis patients and to find out the correlation between each of them, moreover with different disease parameters as temporomandibular joint inflammation may occur without clinical manifestations; it is in need for thorough evaluation and S100A12 may be a future anti-inflammatory treatment in JIA. Twenty patients with Juvenile Idiopathic Arthritis (JIA) and 10 healthy control subjects underwent measurement of S100A12 serum concentrations by sandwich ELISA. Temporomandibular Joints (TMJs); clinical and post contrast Magnetic Resonance Imaging (MRI) examinations were performed.
