Patch Test Results of Contact Sensitization in Children without Atopic Dermatitis: A Single Tertiary Center Experience
Bibliographic record
Abstract
BACKGROUND: Allergic contact dermatitis (ACD) has become more frequent in children. The prevalence of contact sensitization varies with respect to age, sex, and geographic localization. OBJECTIVE: The aim of the study was to investigate the experience of a tertiary health center regarding the patch test results of contact sensitization in children without atopic dermatitis. METHODS: This is a retrospective review of 89 children (30 boys and 59 girls) who were aged between 3 and 18 years and who were diagnosed with ACD between July 2013 and July 2017. Children with a known history of atopic dermatitis were excluded. All patients were tested with the TRUE (Thin-layer Rapid Use Epicutaneous) test series. RESULTS: The most frequently determined allergens by TRUE test were methylchloroisothiazolinone (n = 7 [16.3%]), disperse blue 106 (n = 5 [11.6%]), and bacitracin (n = 5 [11.6%]). Formaldehyde-related allergens produced 15 positives. CONCLUSIONS: Preservatives, such as methylchloroisothiazolinone, formaldehyde, and formaldehyde releasers, emerge as the most frequent allergens in children who undergo patch testing because of ACD. This finding might be attributed to the increase in the utilization of these chemical compounds in personal hygiene products for children.

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.
