Background The application of preparations containing food allergens can cause percutaneous sensitization and provocation. The prevalence of food allergens in children's cosmetics is unknown. Objectives To analyse the prevalence of food allergens in skincare products marketed for children and their association with marketing claims and product price. Methods We reviewed 276 skincare product ingredient labels for the presence of milk, eggs, wheat, soy, oats, tree nuts, peanuts, and sesame. Results More than one‐third (108; 39.1%) of the products listed at least one allergen. A total of 156 allergens were recorded, of which 65 (41.7%) were almonds, 35 (22.4%) wheat, 24 (15.4%) soy, 16 (10.3%) oats, 13 (8.3%) sesame, 2 (1.3%) milk, and 1 (0.6%) peanuts. Products that claimed to be "natural" or "ecological" were more likely to contain food allergens than those not labelled so (P < .001). The prices were higher for products containing food allergens compared with allergen‐free products (P = .028). Conclusions Food allergens are prevalent in children's cosmetics, especially those that claim to be natural or ecological. The most incorporated food allergens are almonds, wheat, and soy. Products containing food allergens cost more than allergen‐free ones.
Background. This study assessed the utility of a prick-by-prick test with pasteurised cow’s milk in predicting a pasteurised cow’s milk allergy (CMA) diagnosis. Methods. This was a retrospective study of 86 paediatric patients who had undergone open pasteurised cow’s milk oral food challenges (OFCs). We evaluated the diagnostic performance of a prick-by-prick test with pasteurised cow’s milk in predicting a positive OFC result. We calculated the threshold values representing high test specificity and predictive probability in children aged ≤24 and >24 months. Results. A prick-by-prick test with pasteurised cow’s milk was a good classifier of a positive cow’s milk OFC outcome. The mean prick − by − prick test wheal diameter ≥ 3 mm yielded 100% sensitivity in both groups of children. Thresholds representing high test specificity and 95% predicted probability were 7 and 11 mm in children ≤ 24 months and 11 and 17 mm in children > 24 months of age, respectively. Conclusion. A prick-by-prick test with pasteurised cow’s milk is valuable in paediatric practice when diagnostic thresholds are implemented.
Introduction: There are no in-depth studies describing the peanut sensitization molecular patterns in Lithuanian children. Aim: To investigate the age-related patterns of molecular peanut sensitization profiles in Lithuanian children with suspected allergic symptoms. Material and methods: We performed a retrospective analysis of peanut sensitization profiles in 576 Lithuanian children with possible allergic symptoms. Patient data were categorized according to age groups: 0-2, 3-6, 7-12, and 13-18 years. Specific immunoglobulin E levels to peanut molecular components:
