FEATURES OF MYCOLOGICAL AND CLINICAL STUDIES OF OTOMYCOSIS

Abstract

The results of our studies made it possible to determine the main pathogenetic factors in the development of otomycosis in the examined patients, which is especially important; since fungi - causative agents of otomycosis are conditionally pathogenic microorganisms and show their pathogenic properties only under certain conditions. We found that an important factor for the development of otomycosis is the presence of general somatic diseases, which, according to the present study, were present in the majority (70.1%) of patients, which indicates a decrease in the body's resistance to opportunistic flora against the background of chronic diseases, various metabolic disorders. 25.7% of patients had diseases of the gastrointestinal tract, in which dysbiosis develops with a decrease in the proportion of obligate microflora, a decrease in natural resistance to fungal flora. Diseases of the cardiovascular system of varying severity, including myocardial infarction, were found in 23.45% of patients. The fact that in 32 patients otomycosis developed against the background of diabetes mellitus testifies in favor of the pathogenetic significance of carbohydrate metabolism disorders in the development of mycosis. A small number of observations and the results obtained did not allow us to state with certainty that there is a direct relationship between the incidence of otomycosis and antibiotic therapy. Analysis of our clinical material showed that prior to the diagnosis of otomycosis, systemic antibiotic therapy according to the anamnesis was carried out in 20 patients, local - in 9 patients (a total of 29 patients - 7.1% of the number of patients with otomycosis). We found that traumatic factors in the form of a systematic toilet of the ear canal with a cotton swab, removal of sulfuric plug, use of endoural headphones play an important role in the development of fungal ear infections. Against the background of trauma, otomycosis developed in 56.5% of patients.
