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.
General information on atopic dermatitis (AD), its history and epidemiological significance are presented. Multiple etiopathogenetic factors affecting disease manifestation are identified. The absence of specific tests, laboratory and histological studies, that can help in correct AT diagnosis, is mentioned. Most of AT diagnostic schemes clarify main (major) and additional (minor) signs of disease. Clinical manifestations of AD minor signs crucial for revealing of subacute and chronic course, as well as onset of incomplete remission of disease are described. Topical AD management regimens are presented. Pathogenetic verifications for emollients and regenerating agents use are presented.
Fast traslate Icon translate Fast traslate Icon translate The progressive increase in the incidence of atopic dermatitis among children, an increase in persistence in adulthood, combined with an inevitable decrease in the quality of life of patients, determine the relevance of studying the mechanisms of the development of this disease not only for dermatology, but also for the entire health care system. Thus, the prerequisites for the emergence of new concepts of pathogenesis and the search for the most effective therapeutic modalities arise. At the moment, atopic dermatitis is considered as the interaction of endogenous (impaired immune response, insufficient function of the epidermal barrier) and exogenous (exposure to allergens, chemical or physical irritants, microorganisms) factors. Environmental factors such as temperature and humidity, genetic makeup, antibiotic use, and good hygiene play a critical role in the maintenance and stability of the skin microbiome. Normally, the skin microbiota is mainly formed by bacteria of the genus Staphylococcus, Propionibacterium, Corynebacterium and Streptococcus. While in patients with AD, in 70% of cases, there is colonization of Staphylococcus aureus on the affected skin, in 39% on intact skin, which secondarily contributes to the development of immune imbalance and increased skin xerosis. This fact determines the importance of the use of basic therapy, which, on the one hand, helps to strengthen the epidermal barrier, and on the other hand, normalizes the microbiome of the skin, reducing the colonization of Staphylococcus aureus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
