Treatment of severe metastatic calcification in hemodialysis patients
Bibliographic record
Abstract
Soft tissue and vascular calcifications are commonly present in uremic patients secondary to disturbances in calcium and phosphate balance and secondary to hyperparathyroidism. We report a uremic patient who developed uncontrolled hyperparathyroidism rapidly within 6 months after commencing hemodialysis (HD) therapy, with clinical presentations of tumoral calcinosis, calciphylaxis, and myocardial calcifications. After treatment with a low-calcium dialysate, non-calcium-containing phosphate binders, and parathyroidectomy, a dramatic resolution of soft tissue calcification was achieved. However, there was relatively little change in the vascular and other visceral calcifications over the 3-month observation period. This case highlights an unusual and rapid development of tertiary hyperparathyroidism, the importance of tight calcium/phosphate control in uremic patients, the potential hazards of a high calcium concentration dialysate, and the dangers of the overzealous use of active vitamin D therapy in HD patients with uncontrolled hyperparathyroidism.

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.
