A Lodged Barramundi Fish-Bone Stabbing the Piriform Fossa in a Child
Bibliographic record
Abstract
Unintentional ingestion of a fish bone is common in children, especially among families with high consumption of seafood. Complications in children are extremely rare. We describe a 3-year-old healthy boy who had a large bone of Barramundi fish lodged in his upper esophagus causing significant distress. Soft tissue neck radiograph revealed a mildly thickened epiglottis and bulbous and hypertrophied adenoid soft tissue. A 21-mm foreign body was noticed. A flexible fiberoptic laryngoscopy revealed a large fish bone emerging from the left piriform fossa and arcing over the left arytenoid to hover over the posterior glottis. The bone was removed during anesthesia induction before a rigid esophagoscopy. The fish-bone entry point was seen stabbing through the edge of the piriform fossa and running down alongside the esophagus, without causing a through and through perforation. Fish bone ingestion can cause significant complications including perforation of the esophagus. Early suspicion of ingestion, radiological investigation, and swift management are important to ensure reduced complication rate in children.

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.
