Auditory symptoms in whiplash patients - could earwax occlusion be a benign cause?
Bibliographic record
Abstract
BACKGROUND: Excess cerumen (earwax) in the external auditory canal is associated with symptoms of earache, fullness in the ears, and diminished hearing. These symptoms, and tinnitus, are commonly associated with whiplash injury. METHODS: Eighty-six whiplash patients were examined to determine if there was a correlation between symptoms of earache, fullness in the ear, diminished hearing, and tinnitus, and the degree of cerumen occlusion. Cerumen occlusion was measured by visualisation of the tympanic membrane and graded according to a 4 point scale. RESULTS: Of 71 subjects reporting no acute onset (within 7 days of the collision that caused their whiplash) earache, fullness in the ears, hearing loss, or tinnitus, 62 had little or no cerenum occlusion. Of seven subjects reporting tinnitus but no other auditory symptoms, none had greater than moderate cerenum occlusion. Of eight subjects reporting one or more of acute onset earache, fullness in the ears, diminished hearing, and tinnitus, seven had complete cerenum occlusion in the affected ear. DISCUSSION: The findings suggest high grade cerumen occlusion frequently occurs in the ear affected by acute auditory symptoms. However, tinnitus alone has no apparent association with cerumen occlusion. It is possible that a significant number of acute onset auditory symptoms reported in whiplash patients have a benign cause.

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.
