An Umbrella as a Potential Foreign Body in the Oral Cavity of the Pediatric Population: Report of Two Cases
Bibliographic record
Abstract
Foreign bodies in the oropharynx of the pediatric population are a well-known subject within the medical field. This report deals with two cases of a very unusual foreign body: an umbrella. Case 1 A 5-year-old boy was brought to the emergency room at the Children's Hospital of Eastern Ontario (CHEO) with the handle of an umbrella protruding through his mouth. The child had fallen face first on the handle while at school. On physical examination, the child was quiet and calm. His vital signs were all stable with oxygen saturation 100% on room air. The umbrella was protruding through his mouth., with minimal bleeding around its handle (Figure 1). Plain film radiography was not helpful because the intraoral part was radiolucent. The patient was rushed to the operating room. Under intravenous sedation, the umbrella was manipulated out of the child's mouth, and then he was endotracheally intubated. A thorough examination under anesthesia and exploration of the oropharynx revealed a 4 cm laceration in the right floor of the mouth, sparing the submandibular duct. There were no other observed injuries. The laceration was repaired primarily. The patient was discharged home on the same day once oral intake was established and covered with oral antibiotics. No long-term sequelae resulted.

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.
