Abstract
Aspiration of scarf pins is a common problem in specific geographical locations where the Muslim population is high, especially in countries like Egypt, Bangladesh, Middle Eastern countries, and certain regions in India. This condition is also referred to as hijab-pin syndrome. We discuss the largest experience of flexible bronchoscopic extraction of aspirated scarf pins from the tracheobronchial tree. A multicenter retrospective observational study was conducted on 146 patients from 4 different centers in Egypt, Bangladesh, India, and Germany. Flexible bronchoscopy was successful in the extraction of aspirated scarf pins in all 146/146 patients with a 100% success rate. 136/146 (93.15%) patients were females, with the most common age group between 12 and 18 years (34.24%). 132/146 (90.4%) remembered the aspiration event before coming to the hospital. Cough was the predominant presenting symptom. (71.22%). In all 146 cases, the foreign body was identified on a standard chest X-ray. The left main bronchus was the most common site of aspiration, 67/146 (45.89%), followed by the right main bronchus, 56/146 (38.35%). 14 patients (9.58%) had a history of unsuccessful attempts to remove by rigid bronchoscopy, and flexible bronchoscopy was successful in these 14 (100%) patients who had a prior unsuccessful attempt to remove. The current series is the largest in literature and demonstrated an excellent success rate in the removal of the aspirated scarf pin.

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
