Abstract

fetched live from OpenAlex

Pheochromocytomas are rare adrenal neoplasms characterized by excess secretion of catecholamines. We describe the case of a 65-year-old man, known for hypertension, with no family history of hereditary pheochromocytoma syndromes. He reported a two-year history of flushing, systolic blood pressure surges to 200 mmHg, headaches, tremors, and syncope. His initial workup revealed elevated 24h urine catecholamines and metanephrines. An adrenal MRI in March 2017 showed a large 7.6 cm heterogeneous right adrenal lesion. Given orthostatic hypotension, his final preoperative dose was limited to a low dose of terazosin and metoprolol. In the operating room, shortly after intubation and Foley insertion, his blood pressure rose to 350 mmHg. Surgery was cancelled and he was admitted to the intensive care unit, where intravenous phentolamine, nitroprusside, and nicardipine were started. His systolic blood pressure would oscillate between 60 mmHg and 350 mmHg at 2-3 minutes' intervals. After 3 days, he was weaned off intravenous medications. His oral medications were uptitrated to high doses of phenoxybenzamine, metoprolol, and nifedipine. Three weeks later, he underwent successful open right adrenalectomy. This case outlines the importance of preoperative preparation of pheochromocytomas and raises the question if phenoxybenzamine is the alpha-blocker of choice for larger tumours with significant hormonal secretion.

Teacher imitation

Not 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.
