Diaper dermatitis (DD) is one of the most common skin conditions in neonates and infants, with a peak between the ages of 9 and 12 months. Appropriate skin care practices that support skin barrier function and protect the buttocks skin from urine and feces are supposed to be effective in the prevention of DD. Despite many recommendations for parents and caregivers on proper diaper skin care, there is no up-to-date synthesis of the available evidence to develop recommendations for DD prevention practice. Therefore we performed a systematic literature review on the efficacy of nonmedical skin care practices on the diapered area of healthy, full-term infants ages 0 to 24 months. We identified 13 studies covering skin care practices such as cleansing, bathing, and application of topical products. DD prevalence and incidence and physiologic skin parameters were used as efficacy parameters. The results of this review indicate that cleansing of the diaper area using baby wipes or water and a washcloth have comparable effects on diapered skin. Bathing with a liquid baby cleanser twice weekly seems comparable with water alone. The application of ointments containing zinc oxide or petrolatum with or without vitamin A seems to have comparable effects on DD severity. There seems to be no information on whether single skin care practices such as cleansing, bathing, and application of topical preparations can prevent DD. High-quality randomized clinical trials are needed to show the effectiveness of skin care practices for controlling and preventing DD.

The findings obtained from this study, with currently largest LPP/FFA patient cohort in Germany, encouraged us to set up a national FFA patient registry. Prospective data collected from larger numbers of patients with standardized questionnaires will help to assess assumed associations and influencing factors and to develop, in the long-term, recommendations for diagnosis and treatment.

Background: Dry skin reflects a skin barrier defect which can lead to atopic dermatitis. Little is known about the distinct effects of emollient use in children with dry skin and atopic predisposition. Objectives: We investigated the effects of daily application of pressed ice plant juice (PIPJ)-based emollients and petrolatum-based emollients. Methods: Children aged 2-6 years with dry skin and atopic predisposition were randomized into 2 groups: group 1 received emollients containing PIPJ and natural lipids, while group 2 received petrolatum-based emollients. Skin condition and biophysical properties of the skin barrier were assessed at inclusion and weeks 4, 12 and 16. Results: Skin condition improved significantly in all children. Comparing the groups, children treated with emollients containing PIPJ showed significantly higher stratum corneum hydration values and significantly lower transepidermal water loss values at week 16 on the forearm and forehead. A significant decrease in skin pH was noted in group 2 on the forearm and forehead; group 1 showed a stable course. Conclusion: Early intervention with emollients in children with dry skin condition and atopic predisposition may improve their skin condition during daily emollient application. PIPJ-based formulations may be helpful to maintain skin barrier integrity.
