A case of Conn's syndrome revealed after oral sodium phosphate (fleet) preparation for colonoscopy
Bibliographic record
Abstract
Oral sodium phosphate solutions (Fleet Mcneil Consumer Healthcare, Guelph, Ontario, Canada) are commonly used as bowel cleansing agents in preparation for colonoscopic exams; however, serious electrolyte disorders associated with oral sodium phosphate use have been described in case reports including hyperphosphatemia, hypocalcemia, hypomagnesemia, hypernatremia, and hypokalemia. We describe a 57-year-old patient with a past history of resistant hypertension who experienced severe symptomatic hypokalemia following colonic cleansing with an oral sodium phosphate solution. Further investigations revealed a serum aldosterone of 691 pmol/L and a serum renin level of 0.02 ng/L/s with a corresponding aldosterone-to-renin ration of 34550:1. The patient was subsequently diagnosed with primary aldosteronism secondary to an adenoma of the adrenal gland. Bilateral adrenal venous sampling revealed excessive levels of aldosterone in the left adrenal vein prior to definitive surgery. This case indicates that an oral sodium phosphate bowel preparation, though safe for most patients, can be complicated by a previously not diagnosed endocrine disease like the primary aldosteronism (Conn's syndrome) reported here. This is the first report of a Conn's syndrome diagnosed after bowel cleansing with a sodium phosphate solution.

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.
