Primary Hyperaldosteronism: Pitfalls in the Diagnosis and a not so Peculiar Evolution - Case Report
Bibliographic record
Abstract
Primar y hyperaldosteronism is now assumed to account for 10-15% of all cases of non selected high blood pressure. The differential diagnosis between bilateral hyperplasia and unilateral adenoma remains however a medical challenge, and the pathogenic stimulus for hyperplasia is still unknown. HS, a female patient aged 32, presented with High Blood Pressure and hypokalemia. An elevated aldosterone/renin ratio and non-suppressed aldosterone levels after saline infusion confirmed the diagnosis of primary hyperaldosteronism. Negative adrenal scintigraphic examination and a marked aldosterone response in the postural test supported the diagnosis of bilateral hyperplasia, despite the presence of left adrenal nodule in the CT-scan. Tetracosactide stimulation revealed a minor 21-hydroxilase defect and a marked ACTH-dependence of aldosterone secretion. Effective treatment with dexamethasone 1.0 mg every other night was maintained for 9 years, while in the meantime the left adrenal nodule apparently resolved and a right adrenal nodule become apparent. Finally worsening of blood pressure levels and increasing aldosterone concentrations with a positive scintigraphic labelling on the right adrenal gland led to right adrenalectomy that was so far curative. This case report demonstrates bilateral hyperplasia-adenoma evolution and suggests ACTH to be the relevant pathogenic stimulus, allowing for effective long-term treatment with dexamethasone. doi: http://dx.doi.org/10.4021/jem113w

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.
