One of the most urgent problems of modern pediatrics is pulmonological and allergic disease. This is due to their high prevalence, severe form of clinical manifestations and constant increase in morbidity, which often leads to deterioration of the quality of life of children, disability and in some cases, death of children. Among them, the most serious diseases are atopic dermatitis, bronchial asthma (BA), allergic rhinitis, diatheses, and these diseases are not only a medical problem, but also a social problem. According to the latest scientific researches, out-of-hospital pneumonias in children are observed with bronchial asthma, allergic rhinitis, atopic dermatitis and diatheses.
