Relevance: Sensorineural deafness is a polyetiological disease. The most studied etiopathogenesis factors are vascular, acoustic and age. Despite numerous studies, the factors of the development and progression of chronic sensorineural hearing loss, as well as tinnitus, remains unclear in 25-30% of cases. Purpose: to determine the most influential factors in the development and progression of sensorineural hearing loss in patients who work in conditions of increased sound load. Methods and materials: The study was conducted on the basis of the Kyiv Clinical Hospital on Railway Transport No. 2, as a division of the Department of Otolaryngology of the O.O. Bogomolets National Medical University. We conducted an examination of 678 patients who work under conditions of increased acoustic load (drivers, drivers' assistants, fitters, railway track fitters) with the aim of identifying perceptual disorders and analyzing the etiopathogenesis factors of chronic sensorineural hearing loss. Further examinations were carried out in 89 patients who had perceptual disorders. Results: The first degree of deafness was detected in 75.3% of patients, the second and third - in 12.35% each. The largest number was made up of patients aged 56 to 65 years, but even among those examined up to 45 years of age, there were 2 cases of third-degree hearing loss. The correlation between age and the degree of deafness in patients with perceptual disorders, as well as age and decreased whisper perception was weakly positive: 0.167 and 0.261, respectively; The relationship between indicators of work experience and the degree of hearing loss, as well as work experience and a decrease in the perception of whispered speech – the average degree of severity is 0.382 and 0.476, respectively. These data were confirmed with the help of two-factor analysis. Conclusions: Among patients with perceptual disorders who work in conditions of increased sound load, the largest number was aged 56-65 with more than 30 years of experience and had the first degree of hearing loss. The relationship between hearing impairment and age and work experience was found to be weak and medium, respectively. 11.1% of cases of third-degree hearing loss were found among patients under 45 years of age and with a work experience of up to 30 years. This may indicate the presence of other factors in them, for example, genetic disorders, which significantly affect the development and progression of sensorineural hearing loss and require further research.

Introduction: Squamous cell carcinomas of the head and neck, including laryngeal cancer, rank sixth in prevalence according to world statistics from developed countries. The role of laryngopharyngeal reflux as one of the risk factors for the development of laryngeal cancer remains controversial and needs further study. Objective: To analyze and compare clinical manifestations and morphological data in patients with laryngeal cancer T1-2N0M0 with LPR. Materials and methods: 87 patients with laryngeal cancer of the I-II stage T1-2N0M0. For the purpose of screening diagnostics of LPR, modified visualanalogue scales RSI and RFS were used,24-hour pH-monitoring was performed. To conduct a histopathological study, samples of surgical material were selected from 8 patients with laryngeal cancer of the I-II stage T1-2N0M0 with LPR; 8 patients with laryngeal cancer – without LPR and 8 patients with benign neoplasms of the larynx with LPR. Results: When analyzing the results of the examination, the RSI index exceeded “9” in 39 (44.8%) patients. According to 24-hour pH monitoring, the presence of LPR was diagnosed in 32 (36.8%) examined patients with morphologically verified squamous cell carcinoma of the larynx, which made up the study group. In 6 (75.0%) patients from the comparison group, areas covered by stratified squamous epithelium were determined within the mucous membrane, in 5 (62.5%) patients, transition zones containing both stratified squamous and single-layered multilayer ciliated were determined epithelium. The nature and intensity of lymphohistiocytic infiltration was more expressed in patients with associated LPR.

Thiol groups of the intra and extracellular molecules are antioxidant and protect cells from damage caused by free radicals, but dynamics data of serum total thiol (sTT) levels in patients at laryngeal cancer are almost absent. Purpose of the study: Determination and comparison the serum total thiol levels at different stages of special treatment methods in laryngeal cancer patients. Material and methods: In twenty-eight laryngeal cancer (T2-3 NX M0 category) patients’ examination of the thiol status dynamics was carried out before, during and after the combined treatment with “ELISA” diagnostics test system. Results: Almost a twofold decrease in sTT content indicators was noted but no identified statistically significant differences between T2 and T3 categories tumors. There was an increase in sTT levels in patients in the postoperative and during radiation therapy period, which, however, were below the control values. At the same time, when the combined treatment was completed, a significant decrease in the level of sTT was noted, which emphasizes the need for long-term antioxidant therapy. Higher sTT levels have been associated with a reduced risk of laryngeal cancer recurrence. Conclusions: In laryngeal cancer patients, the level of serum total thiol was lower than in patients of the control group. There were no statistically significant differences in sTT levels in patients with T2 and T3 tumors. Low levels of the serum total thiol are related with predict a poor outcome for patients.
