ABSTRACT After birth, skin barrier function is in state of flux and at risk of dysfunction. In a prospective clinical study, we compared the effects of 2 standard cleansing procedures on skin barrier function in newborns.
Fifty-seven healthy full-term neonates aged < or = 48 h were randomly assigned to either a bathing group (group B; n = 29), who were bathed with clear water twice weekly, or to a washing group (group W; n = 28), who were washed with a washcloth moistened with clear water twice weekly. Transepidermal water loss (TEWL), skin pH, stratum corneum hydration (SCH) and sebum production were measured at days 2, 7 and 28 of life on the forehead, abdomen, upper leg and buttock.
Group B showed significantly lower TEWL on the buttock and higher SCH on the abdomen and forehead compared to group W at day 28.
Both skin care regimens do not harm the adaptation of the skin barrier in healthy neonates within the first 4 weeks of life. Skin barrier function differentiates after birth in a regionally specific fashion.

    ABSTRACT: 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.

    ABSTRACT: The effect of different diaper care procedures on skin barrier function in infants has been minimally investigated and may be assessed using objective methods. In a single‐center, prospective trial, 89 healthy 9‐month‐old infants (±8 wks) were randomly assigned to three diaper care regimens: group I used water‐moistened washcloths at diaper changes (n = 30), group II additionally applied diaper cream twice daily (n = 28), and group III used wet wipes and diaper cream twice daily (n = 31). Transepidermal water loss (TEWL), skin hydration (SCH), skin pH, interleukin 1α (IL‐1α) levels, and microbiologic colonization were measured in diapered skin (upper outer quadrant of the buttocks), nondiapered skin (upper leg), and if diaper dermatitis (DD) occurred, using the most affected skin area at day 1 and weeks 4 and 8. Skin condition was assessed utilizing a neonatal skin condition score and diaper rash grade. On diapered skin, SCH decreased in groups II and III, whereas TEWL values were reduced in group II only. Skin pH increased in groups II and III. In general, SCH, skin pH, and IL‐1α levels were higher in healthy diapered skin than in nondiapered skin. The incidence and course of DD was comparable in all groups. Areas with DD had greater TEWL and skin pH than unaffected skin areas. Infants who received diaper cream had lower SCH and TEWL and higher pH levels in the diapered area than on nondiapered skin. No correlation with the occurrence of DD was found.

    ABSTRACT: BACKGROUND: In preterm infants, skin barrier maturation entails regional variability. OBJECTIVES: To characterize postnatal skin barrier development in covered, uncovered and diapered regions in healthy premature infants over a longitudinal observation period. METHODS: Transepidermal water loss (TEWL), stratum corneum hydration (SCH), pH and sebum were measured at postnatal ages of 1-7 days and 2-7 weeks on the forehead, abdomen, thigh and buttock of preterm infants (gestational age 30-37 weeks; n = 48) under monitored ambient conditions. A standard minimal skin care regimen was practised. RESULTS: TEWL increased significantly on the buttock (p = 0.007), while remaining stable on the forehead, abdomen and thigh. SCH and sebum remained stable in all studied body regions with increasing age. On the buttock, pH increased (p = 0.049), while other body regions exhibited a significant decrease (p ≤ 0.019). TEWL (p < 0.001) and SCH (p ≤ 0.002) revealed significantly higher values on the buttock, compared to other body regions. CONCLUSIONS: Stable TEWL, SCH and sebum values may indicate a lack of skin barrier maturation. Postnatal decrease in skin pH suggests an adaptation process with acid mantle formation. Differences in skin barrier development were observed between anatomical regions. SCH, TEWL and pH values demonstrated a distinct course in the diaper area, indicating an impaired skin barrier function in this region. © 2014 S. Karger AG, Basel.
