Fatal osmotic demyelination following urgent start hemodialysis in a patient with normal serum sodium
Bibliographic record
Abstract
End stage kidney disease (ESKD) patients in the developing countries often present late for dialysis initiation with advanced uremia and life-threatening complications. Urgent start dialysis in such emergent situations exposes the patient to risk of uremia related complications as well as iatrogenic insults. We report the case of a middle-aged man with ESKD who presented late with acute pulmonary edema and hyperkalemia and developed osmotic demyelination syndrome following urgent start hemodialysis. Osmotic demyelination syndrome in this patient is noteworthy since there was no accompanying hyponatremia, the most commonly recognized antecedent. We propose that rapid lowering of serum osmolality by aggressive hemodialysis is sufficient to incite osmotic demyelination syndrome in patients who have long-standing uremia and high blood urea level. Malnutrition resulting from uremia might be a compounding factor in this scenario. Our patient had a characteristic initial presentation of osmotic demyelination syndrome with locked-in-state which later progressed to respiratory failure and death.

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.
