Abstract

fetched live from OpenAlex

Objectives: This retrospective study enrolled consecutive children aged 2-18 years with developmental and/or epileptic encephalopathy with continuous spike and wave during sleep (D)EE-SWAS who received oral high-dose diazepam therapy. Their clinical, electroencephalographic (EEG), and radiologic data were reviewed and summarized. Results: Thirty-five eligible patients were identified. The mean age at EEG diagnosis of (D)EE-SWAS was 6 years. Focal seizures (57.1%) were most commonly noted at the time of diagnosis. A definite language regression was reported in 10 patients (28.6%). The etiologies included structural (34.3%), genetic (22.9%), and unknown (42.9%). The mean spike-wave index at the time of high-dose diazepam initiation was 88.9% (standard deviation 11%). Sixteen patients (45.7%) showed ≥50% reduction in spike-wave index following the test doses of high-dose diazepam. Most patients tolerated the therapy well. Nonstructural etiology was associated with a good EEG response (β = 2.61, P = .008). The mean duration of follow-up after EEG diagnosis was 6.1 years. All patients were seizure free at last follow-up except one. Persisting SWAS (spike-wave index > 50%) at last follow-up was noted in 12 patients (34.3%). Conclusions: This single-center small retrospective study showed that nearly half of the patients showed ≥50% reduction in spike-wave index following the test doses of high-dose diazepam in patients with (D)EE-SWAS.

Not 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.
