Langerhans Cell Histiocytosis Presenting as Enterocolitis and Shock in Neonate
Bibliographic record
Abstract
INTRODUCTION: Enterocolitis is a relatively common disease in neonatal period that can be a result of many underlying pathologies. One of them, which is an unusual disorder especially in neonatal age and with gastrointestinal involvement, is Langerhans cell histiocytosis (LCH). This case shows a severe neonatal LCH with digestive involvement which required intensive care and had an abnormal presentation, being hard to diagnose attributable to the diversity of symptoms. CASE REPORT: Eleven-day-old newborn presented for excessive weight loss followed by deterioration to shock, abdominal distension, digestive bleeding, and purpuric exanthema. Exploratory laparotomy identified aggressive enterocolitis. After stabilization, a significant hepatosplenomegaly persists as well as bicytopenia, pyrexia, and cutaneous lesions evolving tangible purple. LCH was diagnosed through histology of cutaneous biopsy. CONCLUSIONS: Gastrointestinal involvement in neonatal LCH is infrequent and its symptoms can be really unspecific. It is important to know that the first clinical manifestation is usually dermatologic with very diverse morphologies. Having a high suspect rate will lead us to an early diagnosis with its correspondent impact upon the outcome.

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.
