Hearing in children with fetal alcohol spectrum disorder (FASD).
Bibliographic record
Abstract
BACKGROUND: Alcohol is the most prevalent human teratogen affected by early exposure of the fetus. Although not listed as a major part of the fetal alcohol spectrum disorder (FASD), different texts list hearing loss as a characteristic of the FASD, based on several small studies. OBJECTIVE: To characterize hearing in children with FASD, diagnosed in the Motherisk Program in Toronto. DESIGN: Cross sectional cohort study. SETTING: Academic referral center. PATIENTS: Children 4-16 years of age that met criteria for FASD, with no other known risk factor for sensorineural hearing loss. A consecutive sample of 41 children (13 girls, mean age 8.9 +/-3 years) was collected. INTERVENTION: Physical examination, audiometry and tympanometry. OUTCOME MEASURES: External and middle ear pathology on physical examination, pure tone average (PTA), speech reception threshold (SRT), discrimination and tympanometry. Results were compared to reference values in the normal population. Hearing loss equal or greater than 16dB hearing-level in each frequency tested was considered to be clinically significant. RESULTS: A total of 5 (11.2%) of children had hearing loss of at least 16dB hearing-level, mostly unilateral. SRT was within the normal range in 40 (98%) of children with FASD and discrimination was normal in all children. None had auricular or external canal dysmorphology. 14.7% of the children had frequent episodes of acute otitis media. Middle ear effusion was detected in 8 ears (9.8%). CONCLUSIONS: The prevalence of mild sensorineural hearing loss in children diagnosed with FASD (16dB hearing-level or greater) was not higher than expected in this age group. However, because children with FASD are academically and behaviorally challenged, early detection of hearing loss and early intervention is warranted.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
