Abstract
BACKGROUND: Molecular biologic evidence to support an etiologic role for allergy in the pathogenesis of persistent otitis media with effusion (OME) is lacking. OBJECTIVE: The goal of this article was to document expression of allergy-associated Th-2-type cytokines and inflammatory cells in the middle ear mucosa of children with persistent OME. METHODS: With immunocytochemistry (CD3, major basic protein) and in situ hybridization (interleukin-5 mRNA), middle ear biopsy specimens from 7 children with persistent OME were stained. Nonatopic stapedectomy patients with no history of otitis media served as controls (n = 7). RESULTS: There was a statistically significant (P< 0.05) difference in expression of CD3, major basic protein, and interleukin-5 between experimental and control subjects. All 8 OME patients proved to be atopic by ELISA testing. CONCLUSIONS: Type I allergy involving a Th-2-type cytokine and cellular profile may be a contributing factor in the persistence of OME in atopic children. SIGNIFICANCE: The middle ear may serve as a target organ for allergic inflammation, suggesting that appropriate allergy management may be a useful adjunct to the management of OME.

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
