Postprostatectomy seizures: A case report
Bibliographic record
Abstract
A 75-year-old Caucasian male presented with generalized seizures half-hour post-transurethral resection of the prostate surgery. The intra-operative course was complicated by perforation of the posterior wall of the bladder neck during a difficult Foley catheter placement. This resulted in intraperitoneal extravasation of the glycine containing bladder irrigation fluid. An emergent laparotomy was performed, and 3.5-4 L of fluid was drained from the peritoneal cavity. Postoperative course was complicated by two seizures within a short interval. Patient developed profound hyponatremia (Na of 109 mEq/L). However, measured serum osmolality was normal (283 mOsm/kg). The serum osmolality remained relatively stable, indicating that the absorbed glycine and its metabolites remained osmotically active in the intravascular space (until they were dialyzed as mentioned later), making the hyponatremia less pernicious and an unlikely cause of patient's symptoms. The encephalopathy and seizures were ascribed to accumulation of toxic metabolites of glycine, especially ammonia (serum level -1261 mcmol/L). During a complicated postoperative period, patient developed oligo-anuric renal failure, and was started on slow low-efficiency dialysis for 8 hours resulting in rapid lowering of serum ammonia levels and glycine with reversal of encephalopathy including seizures. There was no recurrence of encephalopathy, seizures, or metabolic acidosis. Although rare, glycine toxicity may be life threatening. The pathophysiology, need for early detection and the role of early use of renal replacement therapy in acute glycine toxicity is discussed below.

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.
