The clinical presentation of paediatric narcolepsy in one Canadian sleep centre
Bibliographic record
Abstract
Narcolepsy is primarily characterized by an overwhelming feeling of sleepiness with or without cataplexy. More recently, there has been a dramatic increase in newly diagnosed childhood narcolepsy and it is hypothesized that H1N1 may play a role in these new cases. The objective of this study is to review the demographics and presenting symptoms of children with narcolepsy in Toronto. Methods: At the Hospital for Sick Children, Toronto, we reviewed medical records and polysomnograms of patients with narcolepsy who presented to the sleep disorders clinic. All patients were referred with a history of excessive daytime sleepiness. Results: View this table: Conclusion: All patients had excessive daytime sleepiness. Interestingly over half of these young patients had cataplexy on presentation. H1N1 vaccination was not given to the majority of these patients. More research is needed to understand the recent increase in the prevalence of childhood narcolepsy with cataplexy.

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.
