Evidence-Based Algorithm for the Evaluation of a Child with Bilateral Sensorineural Hearing Loss
Bibliographic record
Abstract
OBJECTIVE: To develop an evidence-based algorithm for determining the etiology of bilateral sensorineural hearing loss (SNHL) in a child. METHODS: The frequency of different etiologies was previously determined. A systematic review of the literature for articles published between 1940 and January 2003 was performed for studies providing information on the diagnosis of each etiology relevant to their clinical presentation. RESULTS: Connexin mutation testing is highly sensitive and specific. CT scanning of the temporal bones is frequently valuable in detecting inner ear malformations. Routine laboratory studies are rarely helpful. ECG is particularly valuable when a history of syncope or arrhythmias or a family history of sudden death in a young child is elicited. There is no literature to support routine urinalysis for the diagnosis of Alport syndrome and thyroid studies lack specificity in the absence of physical findings (goiter). CONCLUSIONS: An evidence-based algorithm was developed that included: history, physical and audiological evaluation, and ophthalmological evaluation. Further directed investigations may include genetic testing for the Cx26 mutation, CT scan of the temporal bones, ECG and urinalysis.

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.
