Abstract
Thyrotoxicosis attributable exclusively to triiodothyronine (T3) is, by necessity, caused by accidental or intentional ingestion of pharmaceutical preparations. The clinical presentation of T3 overdose appears to differ from classic thyroid storm. A 30-year-old female patient presented serially to the emergency department with headache, nausea and vomiting. Neurological work-up was negative and she was treated for presumed viral gastroenteritis. Eventually she developed confusion and was admitted. Laboratory investigations showed a suppressed TSH and a free T3 above the linear range (>30 pmol/L), estimated by dilution in normal serum to be 330 pmol/L. She was diagnosed with thyrotoxicosis secondary to recently prescribed compounded liothyronine and was treated with seven rounds of plasmapheresis. Using a rapidly developed mass spectrometric method for T3, it was determined that compounding pharmacy had dispensed liothyronine at a concentration ≃1000-times the prescribed dosage. The clinical and mass spectrometry laboratories played an essential role in the diagnosis of thyroid storm in this case of T3 overdose as the expected clinical features of hyperpyrexia, tachycardia and hypertension were initially absent.

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 it
