Convulsive Status Epilepticus in Children with Intractable Epilepsy is Frequently Focal in Origin
Bibliographic record
Abstract
BACKGROUND: Convulsive status epilepticus (CSE) is a common neurological emergency. Our objectives were to study children with recurrent nonfebrile CSE to assess the evidence for focal origin. METHODS: Series of 18 children with recurrent CSE and intractable epilepsy were identified by chart review. Clinical, radiological, and EEG data were reviewed. Focal structural abnormalities were identified on MRI and CT images by one neuroradiologist who was unaware of the clinical details. RESULTS: The patient's ages ranged between 6-22 years (mean 15.3, SD 4), and 67% were males. Most children (89%) had a severe cognitive and / or behavioural disorder. Most patients (89%) had multiple seizure types and 95% of these were partial seizures. Twelve (67%) children had at least one episode of CSE with focal features identified clinically. Focal brain abnormalities were detected on 18% and 55% of CT and MRI films respectively. Overall, 53% had a focal abnormality on structural neuroimaging. Interictal EEG revealed focal or multifocal abnormalities on at least one occasion in 94% and 22% of patients respectively. Overall, 17 patients had focal features on at least one EEG. Thirteen ictal EEGs were recorded on 11 (61%) patients. Ten (91%) of these recordings revealed a focal onset. CONCLUSIONS: Many handicapped children with recurrent CSE have focal clinical, radiological, or electrographic features. This supports a focal origin for CSE in most children with intractable epilepsy.

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.
