Intractable abdominal pain as the sole symptom of Varicella Zoster reactivation after allogeneic stem cell transplantation: brief case report and review of the literature
Bibliographic record
Abstract
After primary infection, Varicella Zoster (VZV) persists in sensory dorsal root ganglia and may be reactivated in periods of diminished T-cell immunity. Varicella Zoster reactivation post allogenic stem cell transplantation (HSCT) can be challenging to diagnose as it does not always present with characteristic skin lesions. We describe a pediatric patient who presented with isolated severe abdominal pain with no other symptoms. Cutaneous lesions appeared only 10 days later resulting in delayed diagnosis and treatment. He was successfully treated with intravenous acyclovir and recovered after a prolonged hospital stay with post-herpetic neuralgia. Abdominal pain in children post HSCT has a broad differential and VZV reactivation should be considered even in absence of cutaneous lesions. Early diagnosis and treatment are essential to reduce VZV-related morbidity and mortality. In this article we present a case report and review clinical presentation and outcome of similar cases in the literature.

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.
