ABSTRACT

Introduction:

Benign acute myositis of childhood (CABM) is a self-resolving clinical picture that usually affects school-age children, characterized by symmetrical calf pain and sudden refusal to walk, and is accompanied by elevated creatine phosphokinase (CK). The aim of our study is to reveal the characteristics of our CABM cases.

Materials and Methods:

Patients who applied to the Pediatric Emergency Department and Pediatrics Outpatient Clinic of our hospital between October 2019 and March 2020 with an upper respiratory tract infection and were diagnosed with CABM were included retrospectively. The patients’ chronological age, hemogram, CRP, AST, ALT, LDH, CK, CK-MB levels recorded in the hospital information management system were evaluated. Statistical analyzes were performed with IBM SPSS Statistics for Windows 22.0 software.

Results:

Of the 52 cases with a mean age of 6.4±2.9 (5.0-12.9) years, 71.2% (n=37) were male. While 92.8% (n=48) of the patients presented with complaints of inability to walk following an upper respiratory tract infection (URTI), 5.8% (n=3) had URTI and abdominal pain; 1.9% (n=1) applied with complaints of URTI and chest pain. The mean serum CK level measured at the first admission was 1777.4±2320.5 (188-11383) IU/L, and a significant decrease was found on the 4^th day of admission, with a mean level of 1104.3±1720.5 (81-7190) IU/L (p=0.011). Similarly, significant improvement was observed in AST, ALT, and LDH levels on the 4th day (p=0.053, p=0.001, p=0.043).

Conclusion:

We found that CABM was observed 2.4 times more frequently in boys than in girls, and the CK level decreased significantly on the 4th day of admission. Although it is a worrying situation due to the sudden and rapid initial findings; It should be kept in mind that it is a benign picture due to its spontaneous and rapid recovery and results in recovery without sequelae, and unnecessary and repetitive examinations should be avoided in this process.
