Abstract
OBJECTIVE: To determine the prevalence of underlying lower airway inflammatory conditions in children who underwent rigid bronchoscopy (RB) for a suspected foreign body aspiration (FBA) in the tracheobronchial tree and to identify the characteristics of patients who could benefit from a trial of antiasthma treatment prior to undergoing a diagnostic bronchoscopy. DESIGN: Retrospective chart review. SETTING: Children with suspected FBA in the tracheobronchial tree who underwent RB at the Montreal Children's Hospital (2001-2009). METHODS: Patient characteristics such as clinical, radiologic, and bronchoscopic findings on presentation, as well as prior use of inhaled bronchodilators or corticosteroids, were analyzed. A p value < .05 was considered significant. MAIN OUTCOME MEASURES: Use of inhaled bronchodilators or corticosteroids, signs, symptoms, and radiologic and bronchoscopic findings on presentation. RESULTS: Fifty-five children underwent an RB for suspected FBA. Foreign bodies were found in 36 subjects. Asthmatics were significantly more likely to have a negative bronchoscopy than nonasthmatics (80.0% vs 30.0%, p < .05). Otherwise, clinical and radiologic findings were not significantly different in these two groups. The median time between the suspected choking event and the first otolaryngology evaluation was 14 days in asthmatics (range 5 hours-90 days), whereas it was 16 hours in nonasthmatics (range 0.5 hours-120 days). CONCLUSION: A conservative approach cannot be justified in suspected asthmatic children with possible FBA, in whom the indications for diagnostic bronchoscopy must be tailored to each patient to ensure a timely diagnosis.

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 it
