ABSTRACT
A total of 1121 workers serving processing unit operators, including operators (n = 673), drivers (n = 201), and fitters (n = 247), were examined at a gas-processing plant (GPP). A complex of negative industrial factors in the gas-processing industry workers was ascertained to be formed due to their exposure to high noise along with class 3.2 hard work. The total rate of the working conditions at the GPP in terms of the intensity of negative industrial factors corresponds to Class 3.3-3.4, which determines the increased likelihood of occupational deafness in the workers.

The workers of the Orenburg gas-processing plant have been found to be at high risk for concomitant diseases of the cardiovascular, central nervous, and other systems in the presence of occupational sensorineural deafness. Among the comorbidities in deaf patients, cardiovascular disease heads the list (63%), of them autonomic vascular dystonia is most common (22%); diseases of the central nervous system and lung rank second (13%) and third (11%), respectively.

The study of the relationship of biological characteristics of staphylococci initiating the inflammation with features of clinical course of maxillary sinusitis has found that staphylococci with virulent characteristics determine acute course of the disease whereas the strains with persistent properties cause chronic course of maxillary sinusitis. Clinical isolates from the purulent discharge and the strains vegetating on the mucosa of the anterior part of the nose appeared identical.

The species composition of microflora was determined and the etiological role of S. epidermidis was shown in some purulent inflammatory diseases (maxillary sinusitis, urethritis). The role of the complex of S. epidermidis persistence factors in the chronization of the infectious process and the formation of the resident carrier state was established.
