Cronkhite-Canada syndrome: a retrospective analysis of four cases at a single medical center
Bibliographic record
Abstract
OBJECTIVE: Cronkhite-Canada syndrome (CCS) is a rare disease that is characterized by multiple gastrointestinal polyps and ectodermal abnormalities. This study aimed to improve the understanding of CCS by presenting our patient data. METHODS: Clinical features, treatment, and outcomes of four CCS patients at a single medical center were retrospectively analyzed. RESULTS: The age of the patients ranged from 32 to 61 years (mean: 49.5 years), including three men and one woman. All the patients presented with gastrointestinal symptoms, ectodermal abnormalities, and multiple gastrointestinal polyps. Two patients showed abnormal immune indices. Three patients underwent magnetic resonance enterography, and the typical manifestations of small intestine involvement were diffuse wall thickening, high signal intensity on diffusion-weighted imaging, obvious enhancement, and multiple small nodular enhancements of the small intestine. The main histological manifestations were chronic inflammation and hyperplastic, adenomatoid, and hamartomatoid polyps. Eosinophilic infiltration was observed in two patients. One patient had rectal adenocarcinoma at the time of diagnosis. All the four patients received prednisone at a dose of 0.75-1 mg/kg/day, and had their gastrointestinal symptoms gradually resolved (including two with ectodermal abnormality and endoscopic remission). Two patients are currently receiving low-dose prednisone (2.5-5 mg/day) with no recurrence after a 1.5- and 6-year follow-up periods, respectively. CONCLUSION: Magnetic resonance enterography has the potential to evaluate small-intestinal lesions in CCSs. Long-term therapy with low doses of prednisone may be beneficial in maintaining remission.

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.
