PedsCases - A Learning Module for Interpretation of Pediatric Abdominal X-Ray for Medical Students
Bibliographic record
Abstract
Abstract This learning module features four multistep clinical cases that review an approach to abdominal X-ray for medical students. The cases go through a 4-month-old presenting with intussusception, an 18-month-old with small bowel obstruction, an 8-year-old with pneumatosis intestinalis, and a 4-year-old with appendicitis. Each case includes several radiographical images and management considerations. This module is a part of PedsCases, a series of comprehensive web-based educational tools that focus on the core objectives of undergraduate pediatric education with extensive student involvement. PedsCases was created for and by medical students and provides an opportunity for active self-directed learning in pediatrics. The learning modalities available include questions, flash card–type quizzes, multistep clinical cases, and podcasts. PedsCases has been used in 96 different countries, and there have been over 10,000 downloads of the available podcasts.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
