Abstract

fetched live from OpenAlex

Abstract Narcotic bowel syndrome is defined as worsening abdominal bloating and cramping with chronic opiate use, leading to paralytic ileus. This syndrome is common yet underreported in adults. However, there is no current evidence of such conditions in the newborn after exposure in utero to high doses of opiates. Our patient was a female indigenous preterm infant born to a mother on a high dose of methadone. On admission at the age of 12 h, she was found to have significant gastric distension. Initial abdominal X-ray showed a large gastric bubble with little evidence of rectal gas. Malrotation was suspected and surgical intervention was discussed. However, repeat abdominal X-ray, ultrasound and upper Gastrointestinal series were found to be normal and without acute findings. Thus, surgery was avoided. The gastric distension resolved spontaneously. She never required opiate therapy for neonatal abstinence syndrome. Given the pattern of gas seen on the initial abdominal X-ray and its spontaneous resolution after removal of maternal methadone, we suspect this baby had neonatal narcotic bowel syndrome. This has never been reported in the literature and is a unique finding. Given the lack of current reports, further observations for this syndrome should be conducted.

Not 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.
