Cronkhite-Canada syndrome with steroid dependency: A case report
Bibliographic record
Abstract
BACKGROUND: Cronkhite-Canada syndrome (CCS) is a rare nonhereditary disease characterized by chronic diarrhoea, diffuse gastrointestinal polyposis and ectodermal manifestations. The lethality of CCS can be up to 50% if it is untreated or if treatment is delayed or inadequate. More than 35% of the patients do not achieve long-term clinical remission after corticosteroid administration, with relapse occurring during or after the cessation of glucocorticoid use. The optimal strategy of maintenance therapy of this disease is controversial. CASE SUMMARY: A 47-year-old man presented to the hospital with a 3-mo history of frequent watery diarrhoea, accompanied by macular skin pigmentation that included the palms and soles, and onychodystrophy of the fingernails and toenails. Gastroscopy and colonoscopy revealed numerous polyps in the stomach and colon. After other possibilities were ruled out by a series of examinations, CCS was diagnosed and treated with prednisone. The patient took prednisone for more than 1 year before achieving complete resolution of his symptoms and endoscopic findings. The patient was then given prednisone 5 mg/d for 6 mo of maintenance therapy. With clinical improvement and polyp regression, prednisone was discontinued. Eight mo after the discontinuation of prednisone, the diarrhoea and gastrointestinal polyps relapsed. Therefore, the patient was given the same dose of prednisone, and complete remission was achieved again. CONCLUSION: It is necessary to extend the duration of prednisone maintenance therapy for CCS. Prednisone is still effective when readministered after relapse. Surveillance endoscopy at intervals of 1 year or less is recommended to assess mucosal disease activity.

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.
