A case of severe, irreversible hypocalcemia after one dose of pamidronate administered for hypercalcemia of malignancy
Bibliographic record
Abstract
This is a case report of a patient who developed severe, irreversible hypocalcemia after receiving one dose of pamidronate 90 mg for hypercalcemia of malignancy. Hypocalcemia is a known risk of bisphosphonate treatments, but the incidence of severe hypocalcemia is rare, and the risk factors are well established. However, in the treatment of hypercalcemia of malignancy, the treatment objective is to reduce the elevated serum calcium level, and the bisphosphonate is usually given as one time dose only. The potential for developing severe hypocalcemia may not be considered a significant concern in this setting compared to the setting of the treatment of bone metastasis, where the baseline serum calcium level is not elevated and the bisphosphonate is administered at a regular interval of every three to four weeks. Furthermore, there is unawareness of prevalence of vitamin D deficiency in cancer patients, especially in those with advanced cancer, which may lead to inadvertent, severe hypocalcemia from bisphosphonate treatment. The objective of this case report is to bring awareness to the risk of severe hypocalcemia in patients with hypercalcemia of malignancy and the high prevalence of unrecognized vitamin D deficiency in cancer patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
