Continuous EEG Monitoring in a Patient With Massive Carbamazepine Overdose
Bibliographic record
Abstract
The authors report a woman who took a massive overdose (OD) of carbamazepine (CBZ). On admission she was unconscious with absent brainstem reflexes and multifocal stimulus-sensitive myoclonus. Continuous EEG recordings showed a burst-suppression pattern with bursts containing only generalized spikes accompanying myoclonic activity. Myoclonus and EEG bursts were both spontaneous and stimulus induced. With treatment, the serum CBZ concentration declined, and the EEG became more continuous and rhythmic without epileptiform discharges. Unfortunately, the patient died from adult respiratory distress syndrome. Autopsy revealed that cortical and subcortical structures were normal without neuronal necrosis or eosinophilia. Massive CBZ OD may produce a reversible encephalopathy that includes cortical hyperexcitability, a profound burst-suppression EEG pattern, and cranial nerve areflexia. Continuous EEG monitoring is helpful in managing seizures that occur as a complication of CBZ OD, after the course of recovery or worsening, and in providing assistance with prognosis.

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.
