Otological trauma resulting from the Soho Nail Bomb in London, April 1999
Bibliographic record
Abstract
We report the otological effects of the April 1999 Soho Nail Bomb on 17 patients. Twenty-one (62%) tympanic membranes were perforated (pars tensa only); 78% closed spontaneously within 6 months. The mean size of the perforation in the tympanic membrane nearer to the blast was significantly larger than the opposite side [33% +/- 8.3 (mean +/- SD) and 13% +/- 4.1 respectively; P = 0.02]. All patients reported hearing losses that were mixed conductive and sensorineural but mainly high-frequency sensorineural (4, 6 and 8 kHz, pure tone average 42.3 dB +/- 20.5). The sensorineural hearing loss correlated inversely with the distance from the explosion but not with the size of perforation. There was no significant difference in the hearing loss between the ear facing the blast and the opposite ear. Fifteen patients (88%) had temporary tinnitus. No patient complained of any vestibular symptoms. The otological effects of a nail bomb in an enclosed space have not been previously reported. Furthermore, an inverse correlation between hearing loss and distance from the explosion and a significant difference in perforation size facing the blast, compared with the opposite side, are also presented for the first time. The high spontaneous closure rate of perforations and minimal ongoing disability from sensorineural losses favour conservative management in most cases.

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.
