Treatment of Malabsorption Vitamin D Deficiency Myopathy with Intramuscular Vitamin D
Bibliographic record
Abstract
A nearly 5 year-old boy presented with proximal muscle weakness, reduced muscle bulk, a positive Gower sign and Trendelenburg gait. He was known to have cholestatic liver disease. Investigations revealed markedly low serum total calcium, elevated alkaline phosphatase, very low serum 25-hydroxyvitamin D, and radiographs consistent with active rickets despite the ongoing administration of a water-soluble preparation of vitamin D. Only i.v. calcitriol acutely corrected the hypocalcemia, despite trying several oral preparations, suggesting that malabsorption secondary to chronic liver disease was the cause of his rickets. Intramuscular calciferol quickly corrected his muscle weakness and X-ray findings. Myopathy secondary to vitamin D deficiency is an uncommon diagnosis in children. Intermittent calciferol is an inexpensive and practical treatment for vitamin D deficiency, especially if associated with malabsorption.

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.
