Value of Minor Salivary Gland Biopsy in Diagnosing Sjögren's Syndrome
Bibliographic record
Abstract
OBJECTIVE: Minor salivary gland biopsy is suggested for diagnosing Sjögren's syndrome in patients with clinical signs of sicca syndrome. This biopsy is mainly examined on the basis of the semiquantitative morphologic criteria without taking into account the detection of characteristic myoepithelial sialadenitis (MESA). DESIGN: The role of minor salivary gland biopsy in the diagnosis of Sjögren's syndrome as a possible detection method for MESA was examined in a retrospective study. METHODS: Minor salivary gland biopsies were obtained from 32 patients between 1986 and 1996. Twenty-two patients fulfilled the criteria for primary and 10 patients for secondary Sjögren's syndrome based on the catalogue of the European Study Group on Diagnostic Criteria for Sjögren's Syndrome. The histopathologic assessment was based on the histomorphologic MESA criteria, that is, parenchymatrophy, interstitial lymphocytic cell infiltration, and myoepithelial cell islands. RESULTS: The histopathologic assessment revealed normal minor salivary glands in 37.5% of the cases and chronic sialadenitis in 59.4% of the patients. Only one female patient (3.1%) had changes characteristic of MESA. CONCLUSION: Minor salivary gland biospy is therefore an unsuitable method for detecting MESA if the pathomorphologic correlative of MESA is used to confirm the diagnosis of Sjögren's syndrome.

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.
