Pediatric push pin aspiration: clinical, radiologic, and pathologic correlation — case report
Bibliographic record
Abstract
Abstract Background Aspiration of foreign bodies is not uncommon in the pediatric setting, and the consideration and recognition of an aspiration event are vital to prompt management. Pointed and sharp-edged foreign bodies have the potential to lodge in the airway and increase the difficulty of identification and removal. Here, we describe a fatal aspiration of a push pin that was unrecognized prior to death. Methods Review of police and medical records was completed prior to postmortem CT imaging and full pediatric autopsy with high resolution photography. Case presentation A 15-month-old boy was playing at home when he acutely vomited and then became unresponsive. Paramedic and hospital physicians performed pediatric CPR protocols, including intubation, without success. Postmortem radiographic imaging revealed a metallic foreign body at the level of the larynx. Autopsy demonstrated a push pin fully occluding the trachea at the level of the vocal cords. Conclusions The diagnosis of aspirated FBs may be elusive, and clinicians and autopsy pathologists ought to be mindful that children with FBs may have atypical presentations. Use of postmortem radiologic imaging can assist in the diagnosis and allow for a targeted autopsy approach to best visualize the offending foreign body.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
