Failing to thrive, abdominal pain and vomiting: A hairy situation
Bibliographic record
Abstract
A 5-year-old boy presented with a 3-day history of crampy abdominal pain, nonbilious vomiting and obstipation. There was no history of abnormal stools, fever or dysuria. After a healthy pregnancy, the child’s birth weight and height were 3.26 kg (25th percentile) and 50 cm (50th percentile), respectively. There were no behavioural or developmental concerns. The child had a well-varied diet in early childhood; however, he demonstrated picky-eating and early satiety 1 year prior to presentation. There was no history of recurrent trichophagia or balding, although at 2 years of age, he was noticed to eat his hair on two occasions. At 3 years of age, his growth velocity decreased which was attributed to his family’s petite characteristics. At 4 years of age, his weight had decreased to the 0.1 to 3rd percentile. He complained of nonspecific abdominal pain and vomiting. An abdominal ultrasound revealed fecal impaction of the large bowel. Treatment with laxatives, a balanced diet and fluids relieved his symptoms until his presentation at 5 years of age.

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.
