Status Epilepticus Amauroticus and Posterior Reversible Encephalopathy Syndrome in Children
Bibliographic record
Abstract
INTRODUCTION: Transient cortical visual impairment is a common aura of occipital lobe seizures. However, status amauroticus for hours has rarely been described as a manifestation of occipital lobe status epilepticus. PURPOSE: To describe status amauroticus caused by focal status epilepticus of occipital lobe origin in two children with MRI findings consistent with posterior reversible encephalopathy syndrome. METHODS: Retrospective review of clinical records of two children who developed status amauroticus in association with posterior reversible encephalopathy syndrome, identified through the EEG database at British Columbia Children's Hospital. RESULTS: Case 1: A 15-year-old boy with chronic renal failure on hemodialysis developed acute headache, hypertension, vomiting, and blurred vision followed by severe visual impairment and a secondarily generalized clonic seizure. EEG demonstrated independent right and left occipital seizures. After phenytoin therapy, visual acuity was 20/20 within 48 hours. Case 2: A 10-year-old girl with beta-thalassemia treated with allogenic bone marrow transplantation developed acute headache, hypertension, severe visual impairment (light perception), encephalopathy, and intermittent dysconjugate gaze. EEG showed status epilepticus of biposterior quadrant origin. After phenytoin treatment, vision normalized within 72 hours. CONCLUSIONS: Reversible status amauroticus because of occipital lobe status epilepticus may be the presenting symptom of posterior reversible encephalopathy syndrome and EEG recording should be performed.

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.
