An Allergy-Based Approach to Orofacial Granulomatosis: A Narrative Review
Bibliographic record
Abstract
The relationship between orofacial granulomatous (OFG) conditions and allergy is evolving. Contact allergies are commonly reported, but the impact of allergy avoidance is unclear, and a current review evaluating this literature has not been performed. We identified 46 studies evaluating the impact of allergen avoidance in OFG (33 case reports, 5 case series, 5 single-arm interventional clinical trials, 1 non-randomized uncontrolled trial, and 2 prospective cohort studies). Patch testing was performed in 158 patients, and the most commonly reported allergens were gold (n = 2), mercury (n = 6), cinnamal/cinnamon (n = 27), sorbic acid (n = 7), grass/silver birch/plant-containing products (n = 22), fragrance (n = 5), nickel (n = 7), and benzoic acid (n = 21). When allergen avoidance was trialed, 123/171 (71%) of patients reported some degree of improvement. A validated scoring/grading system for Granulomatous Cheilitis, Melkerrson-Rosenthal syndrome, and OFG has not been developed, so we were unable to formally assess improvement, instead relying on physician- and patient-reported outcomes in addition to oral disease severity score reporting in several studies. Current literature supports both patch testing and a trial of allergen avoidance/elimination diet to improve OFG in those with a positive result. Few controlled studies have been performed to assess this relationship, and more are needed to evaluate the impact of allergen avoidance. If a patient with difficult-to-treat OFG has a positive patch test and exposure to allergens in their diet, we would recommend a trial of allergen avoidance/elimination diet to facilitate a multimodal approach to improving control of this difficult condition.

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.
