Acute Fatal Peritonitis: A New Organism for Consideration
Bibliographic record
Abstract
A 40-year-old man died suddenly and unexpectedly at home. His comorbid conditions included central diabetes insipidus, obesity, and hypertension. Autopsy revealed acute and chronic pancreatitis with an abscess and associated purulent peritonitis. Peritoneal fluid cultures grew Raoultella planticola and a light growth of Candida albicans. The organism isolated, R. planticola, is a waterborne bacterium with limited previous clinical isolates causing morbidity but no previously described mortality. Vitreous humor analysis demonstrated concomitant acute water intoxication complicating the decedent's diabetes insipidus. Discussion includes a review of the literature with a description of the eight previous cases of human infection with R. planticola, a recently described organism that was previously in the genus Klebsiella. The proposed fatal pathogenesis includes retrograde entry of the organism from the gastrointestinal tract via the pancreatic duct to the pancreas and subsequent peritonitis. This is the first reported fatality caused by this organism.

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.
