Navigating treatment dilemmas in severe paediatric IDA: A case report
Bibliographic record
Abstract
Iron deficiency anemia (IDA) is a leading cause of anemia worldwide, often managed with oral iron. Severe paediatric cases, however, raise uncertainty about when to use packed red blood cell (pRBC) transfusion versus intravenous (IV) iron. We report a 16-year-old male with autism spectrum disorder and severe nutritional IDA (hemoglobin 31 g/L) who presented with tachycardia and hypotension but no acute decompensation. Although transfusion was discussed, the patient declined, and he was managed with IV iron followed by oral supplementation. Hemoglobin recovery was brisk, rising by 13 g/L within 5 days, but functional recovery was slow, taking 6 months. This case highlights the therapeutic dilemma in adolescents with chronic severe IDA who may meet criteria for transfusion yet remain clinically stable. IV iron offers a viable alternative in this setting, but paediatric guidelines are needed to better define transfusion thresholds and the role of IV iron.

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.
