Systemic Contact Dermatitis from Propylene Glycol
Bibliographic record
Abstract
A 39-year-old woman presented with pruritic eczematous plaques on her face, neck, and right hand that she had had for approximately 2 months, following an abrasive injury caused by the deployment of an airbag in a car accident. Results of patch testing were positive for several medicaments and propylene glycol (PG). The patient's condition cleared after discontinuation of all topical products containing PG and her other identified allergens, but she noted flares of her contact dermatitis following the ingestion of foods containing PG. A subset of patients will have a recurrence of dermatitis after the ingestion of a contact sensitizer. Recurrent dermatitis despite complete avoidance of identified topical allergens and a history of recurrent eczema at the patch-test site are clues to the diagnosis of systemic contact dermatitis. Even weak patch reactions to PG, if they persist to a day-7 reading, should be considered potentially relevant. Avoidance of dietary PG includes attention to labels on food and medication and the avoidance of certain foods in restaurants when ingredients cannot be verified.

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; both teacher heads agree on what is shown here.
