MR spectroscopy in pediatric Wernicke encephalopathy
Bibliographic record
Abstract
The patient is a 7-year-old girl with a history of repaired gastroschisis and short gut syndrome. She presented with a 4-day history of progressive encephalopathy, truncal ataxia, and omnidirectional gaze-evoked nystagmus. Peripheral lactate was 7.1 mmol/L. Serum thiamine level was decreased (<5 nmol/L). Brain magnetic resonance with spectroscopy is shown in the figure. A clinical diagnosis of Wernicke encephalopathy was made. The patient was started on thiamine and demonstrated a rapid clinical recovery. Peripheral lactate normalized within 1 day. Increased lactate has been reported in thiamine deficiency, presumed secondary to the role of thiamine as a cofactor for the pyruvate dehydrogenase complex and α-ketoglutarate dehydrogenase.1

How this classification was reachedexpand
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.
