The article provides general information about the skin physiology of newborns and infants. Structural features of the skin and main adaptive shifts in newborns, are described. Тhe child has an increase in the skin barrier function of the skin, which prevents transepidermal water loss; active synthesis of natural moisturizing factor (NMF) components that control skin hydration; shift of pH to acidic environment; normalization of thermoregulatory functions; enhancement of the photoprotective function; immune restructuring for antimicrobial protection; formation of a normal microbiome. The article describes the consequences of improper skin care of a newborn, using the example of diaper dermatitis, irritant dermatitis, prickly heat and vesiculopustulosis. The importance of using specialized children's cosmetics in caring for an infant is assessed. The basic recommendations for the choice of these products are presented, where the main emphasis is on the choice of products consisting of natural ingredients. Giving preference to natural cosmetics, everyone should carefully study the composition of these products and trust the manufacturers who can guarantee safety of care products for the youngest children.

AbstractRecent developments of molecular biology have revealed diverse mechanisms of skin diseases, and precision medicine considering these mechanisms requires the frequent objective evaluation of skin phenotypes. Transepidermal water loss (TEWL) is commonly used for evaluating skin barrier function; however, direct measurement of TEWL is time-consuming and is not convenient for daily clinical practice. Here, we propose a new skin barrier assessment method using skin images with topological data analysis (TDA). TDA enabled efficient identification of structural features from a skin image taken by a microscope. These features reflected the regularity of the skin texture. We found a significant correlation between the topological features and TEWL. Moreover, using the features as input, we trained machine-learning models to predict TEWL and obtained good accuracy (R2 = 0.524). Our results suggest that assessment of skin barrier function by topological image analysis is promising.

Multiple diagnostic tools are used to evaluate psoriasis and atopic dermatitis (AD) severity, but most of them are based on subjective components. Transepidermal water loss (TEWL) and temperature are skin barrier function parameters that can be objectively measured and could help clinicians to evaluate disease severity accurately. Thus, the aims of this study are: (1) to compare skin barrier function between healthy skin, psoriatic skin and AD skin; and (2) to assess if skin barrier function parameters could predict disease severity. A cross-sectional study was designed, and epidermal barrier function parameters were measured. The study included 314 participants: 157 healthy individuals, 92 psoriatic patients, and 65 atopic dermatitis patients. TEWL was significantly higher, while stratum corneum hydration (SCH) (8.71 vs. 38.43 vs. 44.39 Arbitrary Units (AU)) was lower at psoriatic plaques than at uninvolved psoriatic skin and healthy controls. Patients with both TEWL > 13.85 g·m−2h−1 and temperature > 30.85 °C presented a moderate/severe psoriasis (psoriasis area severity index (PASI) ≥ 7), with a specificity of 76.3%. TEWL (28.68 vs. 13.15 vs. 11.60 g·m−2 h−1) and temperature were significantly higher, while SCH (25.20 vs. 40.95 vs. 50.73 AU) was lower at AD eczematous lesions than uninvolved AD skin and healthy controls. Patients with a temperature > 31.75 °C presented a moderate/severe AD (SCORing Atopic Dermatitis (SCORAD) ≥ 37) with a sensitivity of 81.8%. In conclusion, temperature and TEWL values may help clinicians to determine disease severity and select patients who need intensive treatment.

AbstractCold atmospheric plasma (CAP) has been incorporated into various fields, including promotion of cutaneous wound healing. Atopic dermatitis (AD) is a chronic cutaneous condition characterized by inflammation-induced skin wounds and impaired skin barrier function. To investigate whether CAP may improve AD using an animal model. Dermatophagoides farinae extracts (DFE)-induced murine models of AD were used in this study. The plasma-treated group received a total of 6 CAP treatments during 2 weeks, while the control group did not receive any treatment. Differences in dermatitis severity, transepidermal water loss (TEWL), serum level of immunoglobulin (Ig) E and epidermal thickness were evaluated in both groups. The dermatitis severity was significantly improved by CAP treatment. TEWL was lower in the plasma-treated group compared with the non-treated control group. Serum Ig E dropped significantly after treatment with CAP. Difference in epidermal thickness of the ear skin was not significant between the plasma-treated and non-treated groups. Localized treatment of AD with CAP decreases dermatitis severity, TEWL, and serum Ig E level. These results show CAP’s potentials as a novel therapeutic modality for AD.

Plants of the genus Wikstroemia have long been used as traditional medicines to treat diseases like pneumonia, rheumatism, and bronchitis. This study was designed to determine the effect of chamaejasmine, a biflavonoid present in W. dolichantha, on atopic dermatitis (AD)-like skin lesions in a 2,4-dinitrochlorobenzene (DNCB)-induced murine model of AD. Initially, we examined the anti-allergic activities of ten flavonoids from W. dolichantha by measuring β-hexosaminidase release from RBL-2H3 cells. Subsequently, an SKH-1 hairless mouse model of AD was developed based on the topical application of DNCB. Chamaejasmine (0.5%) or pimecrolimus (1%, positive control) were applied to dorsal skins of DNCB-sensitized AD mice for two weeks. Serum IL-4 and IgE levels were determined using enzyme-linked immunosorbent assay kits and transepidermal water loss (TEWL) and skin hydration were measured using a Tewameter TM210 and a SKIN-O-MAT, respectively. Of the ten flavonoids isolated from W. dolichantha, chamaejasmine most potently inhibited DNP-specific IgE-induced degranulation in RBL-2H3 cells. Topical administration of chamaejasmine attenuated the clinical symptoms of DNCB-induced dermatitis (i.e., itching, dryness, erythema, and edema). Histological analyses demonstrated that dermal thickness and mast cell infiltration in dermis were significantly reduced by chamaejasmine. In addition, 0.5% chamaejasmine inhibited DNCB-induced increases in total IL-4 and IgE levels in serum, improved skin barrier function, and increased epidermis moisture. Our findings suggest chamaejasmine might be an effective therapeutic agent for the treatment of atopic diseases.

Skin physiology is dynamically changing over the first years of postnatal life; however, ethnic variations are still unclear. The aim of this study was to characterize infant skin barrier function, epidermal structure, and desquamation-related enzymatic activity as compared to that of adult skin in an East Asian population. The skin properties of 52 infants (3-24 months) and 27 adults (20-40 years) were assessed by noninvasive methods at the dorsal forearm and upper inner arm. Transepidermal water loss and skin surface conductance values were higher and more dispersed for infants compared to adults. Infant skin surface pH was slightly lower than adult on the dorsal forearm. The infant SC and viable epidermis were thinner compared to adults with differences that were site-specific. Although the chymotrypsin-like activity for infant skin was comparable to adult level, the caseinolytic specific activity was significantly higher for the infant cohort. These observations indicate a differently controlled pattern of corneocyte desquamation in infants. In conclusion, structural and functional differences exist between infant and adult skin in the East Asian population pointing to dynamic maturation of the epidermal barrier early in life.

Introduction: Cast immobilisation remains the mainstay of treatment for various fractures in paediatric patients, yet patients commonly complain of skin irritation and discomfort. This study aimed to perform a qualitative and quantitative evaluation of the effects of cast immobilisation on the skin of children and adolescents. Materials and Methods: Patients aged 6–17 years of age with a fracture treated in a fiberglass short-arm or short-leg cast were recruited. Transepidermal water loss (TEWL), stratum corneum (SC) hydration, hair density and presence of any skin signs were assessed before and after cast. Patients were required to complete a weekly questionnaire to rate itch, malodour, warmth, and dampness of the skin under the cast. Results: A total of 60 subjects completed the study. Thirty-six patients received a short-arm cast; 24 received a short-leg cast. Upon cast removal, TEWL was significantly increased on the volar surface of the arms and legs (P <0.05), and the dorsal surface of the arm (P <0.05). Likewise, SC hydration was significantly increased at most sites (P <0.05), except the volar surface of the leg (P = 0.513). There was no change in hair density. Throughout the duration of casting, there was an increase in itch and malodour scores. Conclusions: Moderate but significant changes in TEWL, SC hydration and subjective symptoms were observed during the duration of cast immobilisation, demonstrating that cast immobilisation for up to 4 weeks exerts moderate adverse impact on patients’ skin. Further studies to explore the use of better materials for cast immobilisation to improve skin barrier function and overall patient satisfaction are warranted.

Background. Structural and functional damages of the epidermal barrier in patients with atopic dermatitis promote the entry of allergens and development of Th2-type allergic inflammation. Moisturizers containing lipids increase the physiological antiinflammatory effects of topical corticosteroids (TGKS), improve the epidermal barrier and reduce the duration of TGKS using preventing further infringement barrier. To evaluate the clinical efficacy of emollient milk Xemose in children with atopic dermatitis. Materials and methods. We examined 27 children with atopic dermatitis. Children were divided into 2 groups: patients in group 1 (n=14) used emollient milk Xemose twice a day on the skin lesions and limbs in the complex therapy, patients in the 2nd group (n=13) received combined therapy incorporating traditional dampening agents on the basis of lanolin (Unna cream) 3 times daily. All patients underwent measurement of transepidermal water loss (TEWl) (Tewameter TM 300, Multi Probe Adapter MPA 5/9, Courage + Khazaka) and the pH of the skin (Skin-pH-Meter, Multi Probe Adapter MPA 5/9, Courage + Khazaka) before and after 2 weeks of therapy. Results. Patients in groupthat used Xemose milk and children in group with Unna cream after 2 weeks showed a statistically significant decrease of TEWl (p=0,041 and p=0,04, respectively). TEWl was significantly lower in children treated for 2 weeks with milk Xemose (p=0,027) than in children treated with Unna cream. in both groups pH skin surface have not changed (р=0,22 and р=0,22 respectively). Conclusion. Clinical efficacy of milk Xemose as compound improving skin barrier function in children with atopic dermatitis was shown.

Immune Dysfunctions

The gut intestinal tract harbours a complex microbiota. Disturbances in the microbiota composition have been associated with several immune dysfunctions such as inflammatory diseases. Specific strains of probiotics have shown to beneficially influence the composition and/or metabolic activity of the endogenous microbiota. Taking advantage of the plasticity of the immune system, the probiotic strain NCC2461 (i.e. ST11 or CNCM I-2116) supports and/or restores homeostasis in reaction to different physiopathological conditions. The potential of NCC2461 to modulate both mucosal and systemic immune functions led us to test its impact on skin physiology. Even though clear mechanisms explaining gut-skin interaction are still lacking, a set of experimental and clinical data reviewed herein have shown that NCC2461 exerts its effects beyond the gut and confers benefits at the skin level. It contributes to the reinforcement of skin barrier function, decreases skin sensitivity and modulates the skin immune system leading to the preservation of skin homeostasis.

(1) Background: The aim of the study was to evaluate the effect of pure lecithins in comparison to a conventional surfactant on skin in vivo. (2) Methods: Physiological skin parameters were evaluated at the beginning and the end of the study (day 1 and day 4) (n = 8, healthy forearm skin) with an Aquaflux®, skin-pH-Meter, Corneometer® and an Epsilon® sensor. Confocal Raman spectroscopy was employed to monitor natural moisturizing factor, urea and water content of the participants’ skin. Tape strips of treated skin sites were taken and the collected corneocytes were subjected to atomic force microscopy. Circular nano objects were counted, and dermal texture indices were determined. (3) Results: Transepidermal water loss was increased, and skin hydration was decreased after treatment with SDS and LPC80. Natural moisturizing factor and urea concentrations within the outermost 10 µm of the stratum corneum were lower than after treatment with S75 or water. Dermal texture indices of skin treated with SDS were higher than skin treated with water (control). (4) Conclusions: Results suggest very good (S75) or good (LPC80) skin-tolerability of lecithin-based surfactants in comparison to SDS and encourage further investigation.
