Prostaglandin-Induced AntralHyperplasia in Neonates:Clinical Experience andDose-Response Characteristics
Bibliographic record
Abstract
Antral hyperplasia (AH) induced by prostaglandins (PG) has been described by us recently in 5 infants with cyanotic heart disease receiving the drug. The purpose of the present study was to analyze 14 infants diagnosed as having AH either sonographically or pathologically in an attempt to characterize the dose-response characteristics of this adverse drug reaction, its clinical course and its optimal management. Infants with AH exhibiting large gastric aspirates have received a significantly lower cumulative dose (1,633 +/- 1,266 micrograms/kg) than those presented also with a palpable mass (3,458 +/- 1,703 micrograms/kg), (p < 0.01). While in general there is a dose-related clinical toxicity, variability in the location of the hyperplasia can explain cases of no apparent obstruction despite large cumulative doses of PG. In asymptomatic cases the antral hyperplasia, although visualized, it did not result in gastric outlet obstruction. In all cases followed by us to date, discontinuation of the PG has resulted in resolution of the clinical and sonographic findings. Nasojejunal tube was successfully attempted in several cases, preventing surgery in these very-high-risk infants.

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.
