Childhood chronic daily headache: a biopsychosocial perspective
Bibliographic record
Abstract
The aim of our observational study was to highlight some clinical observations on chronic daily headache (CDH) in children and adolescents. Data on patients < or =18 years aged presenting with CDH to the Pediatric Headache Clinic at the Royal University Hospital, Saskatoon, Canada, were collected prospectively and sequentially from February 2004 to July 2006. Standardized data sheets and definitions were used. Follow-up information on the 70 participants (22 males, 48 females) was current to February 2007. Fifty-four participants (77%) had had recurrent headaches before transformation to CDH. Comorbid chronic migraine and chronic tension-type headache was the most frequent subtype of CDH (37 participants; 53%). Anxiety and mood disorders were diagnosed in 17 and 15 children respectively. Stressors that precipitated or contributed to the maintenance of CDH were judged important in 44 (63%). The possibility of a somatoform disorder was considered in five children, a factitious disorder in one, and malingering in another. We suggest that CDH be viewed from a biopsychosocial rather than a narrow biomedical perspective and the classification improved to enhance clinical utility.

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.
