Unusual Case of Proximal Calciphylaxis without Renal Failure
Bibliographic record
Abstract
BACKGROUND: Calciphylaxis is a rare syndrome of vascular calcification with subsequent cutaneous and tissue necrosis. It usually manifests as a complication of end-stage renal failure, affecting 1 to 4% of long-term dialysis patients. Very exceptionally, it can occur without chronic renal failure. OBJECTIVE: The goal of this study was to discuss an exceptional case of extensive calciphylaxis in the absence of chronic renal failure and its successful management. METHODS: We present a case of a 31-year-old woman with extensive proximal, ulcerated calciphylaxis without associated chronic renal failure. Our patient had quite a few risk factors associated with the pathogenesis of calciphylaxis, such as obesity, malnutrition, and a transient episode of acute renal failure. RESULTS: She was successfully treated with sodium thiosulfate, extensive wound débridement (more than 30% total body surface), and subsequent skin grafts. The patient has miraculously survived this often fatal condition. CONCLUSION: Calciphylaxis can occur even in the absence of chronic renal failure. This often fatal condition can be managed successfully with a combination of aggressive wound control and the fairly newly described sodium thiosulfate therapy.

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.
