Abstract
Multiple complications of varicella have been described. Musculoskeletal complications (osteomyelitis, septic arthritis, and necrotizing fasciitis) as well as neurologic complications (ataxia, encephalitis, and transverse myelitis) are well-known. We describe the cases of 2 children, ages 18 months and 5 years, who were admitted recently to 2 pediatric hospitals in Montreal with a resolving varicella, abdominal and lumbar pain, and a refusal to walk and in whom a diagnosis of epidural abscess caused by group A streptococcus (GAS) was established. No previous case of epidural abscess caused by GAS in the context of varicella has been reported. Epidural abscesses are rare in pediatrics and are caused mainly by hematogenous spread of Staphylococcus aureus. The diagnosis in pediatrics is challenging because it is rare and does not present as classically as in adults. The prognosis is related to the presence of neurologic deficits before surgery and to the rapidity with which the diagnosis and the intervention are made. These cases highlight a new clinical association in children of epidural abscess caused by GAS and varicella. An early clinical diagnosis requires a high index of suspicion when back or abdominal pain with or without neurologic signs and symptoms occurs during or soon after varicella.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
