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: The measurement of transepidermal water loss (TEWL) is important for evaluating the integrity of the barrier function of the stratum corneum. Normal TEWL values in healthy adults and in children ages 2 and older are well known, but few studies have been performed in infants and neonates. TEWL in healthy neonates younger than 24 hours old was assessed and compared with that of an adult study population. We also studied possible correlations between this parameter, gestational age, and mode of delivery. A prospective study was conducted in healthy newborns. The areas tested were the volar forearm and the popliteal fossa. Ninety-nine healthy newborns were enrolled and 33 healthy adults were analyzed as controls. Statistically significant differences were noted between newborns and adults in TEWL (p < 0.01). Newborns had a much higher mean TEWL than adults. Differences in the morphology and physiology between newborn and mature skin can explain the higher TEWL in newborns. Higher TEWL could also be due to the sudden functional adaptation of the skin immediately after delivery, when the newborn transits from a liquid to the dry, gaseous extrauterine environment. Functional evaluation of the neonatal skin barrier is important mainly because maintaining skin integrity facilitates cutaneous adaptation.

    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 skin of neonates and infants exhibits distinct anatomical and functional properties that might be clinically reflected by its characteristic susceptibility to skin barrier disruption. In this systematic review, we aimed to characterize skin barrier maturation as reflected by transepidermal water loss (TEWL) and skin surface pH during the first 2 years of life. We systematically searched MEDLINE and EMBASE via OVID from 1975 to 2013 to identify primary studies reporting TEWL and/or skin surface pH values in healthy full-term infants aged 0-24 months without any cutaneous diseases. After full text assessment, 36 studies reporting n = 8,483 TEWL measurements for 26 anatomical areas and n = 6,437 skin surface pH measurements for 14 anatomical areas were included. The mean age of the subjects ranged from 1.4 h to 1.2 years. The lowest pH of 4.63 was identified on the forehead at the age of 25.6 weeks, whereas the highest of 7.31 was on the volar forearm at 0.0 weeks. The lowest TEWL value of 3.1 g/m(2)/h was reported for the back at 0.6 weeks and the highest of 43.1 g/m(2)/h for the upper leg at 58.7 weeks. The skin surface pH reveals a steep decline during the first postnatal week, succeeded by a further gradual site-specific acidification process during the first month. A competent permeability barrier in most anatomical areas is indicated by TEWL, which does not exhibit a time-dependent development during the first 2 years of life.
