Outcome of Benign Acute Childhood Myositis
Bibliographic record
Abstract
OBJECTIVE: The aims of the study were to determine the evolution of benign acute childhood myositis in children and to assess the relationship between creatine phosphokinase (CPK) values and myoglobinuria. STUDY DESIGN: A retrospective study of patients with benign acute childhood myositis seen in 2 tertiary care university-affiliated pediatric hospitals during overlapping 4-year periods. METHODS: Demographic data, historical details, clinical, and laboratory results were extracted from the charts of children younger than 16 years with a CPK greater than 3 times normal. Complications, treatments, and outcomes were recorded. RESULTS: Fifty-four children were included, 43 (80%) were male, and mean age was 7.3 years (median [range], 6 [3-16] years), none showed abnormal neurological findings, manifested hematuria, or developed renal failure. Mean CPK level at presentation was 1872 IU/L (range, 511-8086 IU/L). None developed renal failure, and there were no adverse outcomes on follow-up. CONCLUSIONS: Acute childhood myositis is a predominantly benign disease. Neurological examination is usually normal and rhabdomyolysis is rare. Although severe pathological comorbid conditions must be excluded, a complete history and examination, coupled with simple blood and urine tests, can help minimize unnecessary diagnostic investigations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
