Benign acute childhood myositis in Kuwait.

Ten children, three girls and seven boys, aged 4-10 years, were admitted with benign acute childhood myositis during spring and winter months (March 1988 to March 1990). They presented with an acute onset of symmetrical calf muscle pain and tenderness, weakness and inability to walk a few days after a flu-like illness. All had raised serum creatine kinase and a normal erythrocyte sedimentation rate, and the majority had low peripheral white blood cell counts with relative lymphocytosis.
