title: [Diseases of the lymphopharyngeal ring in the employees engaged in dust-producing industries].
abstract: The objective of the present work was to study changes in the mucous membrane of the upper respiratory tract of the employees subjected to the action of industrial aerosols. The clinically and functionally significant mucosal changes in the nasal cavity and pharynx induced by industrially-derived irritants are described, the classification of nosological forms of the diseases of upper respiratory tract is proposed based on the character and extent of the pathological process, the criteria for occupational chronic rhinopharyngolaryngitis have been developed. The frequency of development of pathological changes in the mucous membrane of the upper respiratory tract (UPT) in the workers undergoing effects of industrial aerosols (IA) is shown to amount to 89%. The highest dust concentrations to which such persons were exposed are known to occur in coal, metal, timber, textile, and cotton industries as well as in certain branches of machine-building and agricultural industries. The industrial environment not infrequently contains dust of the mixed composition, such as mineral, metallic, organic, and synthetic particulate components. The authors propose the classification of pathological changes in the UPT mucosa. It is emphasized that rhinopharyngolaryngites are included in the List of occupational diseases approved by the Russian Ministry of Health on 27 April 2012.
