Clinical features of taste disorders in Cronkhite-Canada syndrome: a report of 10 cases
Bibliographic record
Abstract
Cronkhite-Canada syndrome (CCS) is a very rare gastrointestinal disorder with ectodermal abnormalities. Taste abnormalities appear in more than 80% of cases. Our objective was to investigate the characteristics of CCS. Ten patients with taste abnormalities who were diagnosed with CCS were included. A medical interview, examination of the tongue findings, and blood tests were performed, and taste functions were assessed using an electrogustometry (EGM) and a filter paper disc (FPD) before and after treatment. There was nail atrophy in all cases, weight loss in 8 cases, hair loss in 6 cases, skin hyperpigmentation in 5 cases, gastrointestinal symptoms in 4 cases, and atrophy of the lingual papillae in at least 8 cases. Zinc therapy for taste disorders by the previous physicians was ineffective in all cases. The results of the FPD at the first examination showed a severe decrease in taste function of the anterior tongue, whereas taste function tended to be preserved in the posterior tongue (P < 0.01, Wilcoxon). In all cases, subjective symptoms improved within 3 mo after treatment of CCS. Taste function improved significantly after treatment (FPD in anterior tongue, P < 0.05, EGM in posterior tongue, P < 0.01, Wilcoxon). Taste disorder in CCS tended to be severe in the anterior tongue with findings of tongue papillary atrophy, which appears to be an ectodermal abnormality. Their taste function improved along with symptoms after treatment. The taste tests were useful for determining the effect of treatment for CCS.

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.
