ACUTE STENOSING LARYNGOTRACHEITIS IN RESPIRATORY VIRAL INFECTIONS IN CHILDREN IN THE CLINICS OF ST. PETERSBURG

A comparative analysis of the development of acute stenosing laryngotracheitis (LSLT) in respiratory viral monoinfections in 1050 children, hospitalized in St. Petersburg hospitals. It was established that the clinical manifestations, severity and outcome of OSLT in viral monoinfections depend highly on the etiologic factor, the patient's age and his premorbid background. More often, stenoses of the larynx are provoked by parainfluenza viruses (26,7%), the next most important are the PC virus (22,3%) and adenoviruses (18,8%), but during epidemics the number of lesions of the larynx sharply increases, with influenza viruses as the main pathogen, reaching up to 31,1%. Boys (71,2%) suffer from LSLT more often than girls (28,8%). Burdened premorbid background were 88,1% of children.
