OBJECTIVE: Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute @entity1800 . METHOD: A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of @entity1729 and musculoskeletal symptoms, measurement of muscle enzymes, @entity908 phosphokinase (CPK), @entity880 dehydrogenase (LDH), transaminases ( @entity6571 and ALT), blood count, @entity1851 , and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. RESULTS: Between 2000 and 2009, 42 suspected cases were identified and 35 (27 @entity1 ) were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%), @entity5254 (23%), and @entity221 (63%), with a mean duration of 4.3 days. Musculoskeletal symptoms were @entity158 in the @entity291 (80%), limited ambulation (57%), gait abnormality (40%), and @entity425 in the lower limbs (71%), with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507  9180U/L), LDH (827  598U/L), and @entity6571 (199  245U/L), with a tendency to @entity1431 (4590  1420) leukocytes/mm(3). The complete recovery of laboratory parameters was observed in 30 days (median), and laboratory and clinical recurrence was documented in one case after 10 months. CONCLUSION: Typical symptoms with increased muscle enzymes after diagnosis of @entity683 and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal @entity683 , which should be considered, regardless of the viral identification, possibly associated with @entity683 virus or other respiratory viruses.
