According to the data of targeted examinations of workers with hazardous working conditions, in particular, in the presence of a radiation factor, the dental status in terms of the prevalence and intensity of major dental diseases does not differ significantly from those working in normal working conditions. At the same time, during interviews and clinical examination, workers in hazardous industries often reveal hypertonicity of the muscles of the maxillofacial region, which is especially noticeable in people with long work experience. One of the reasons for the hypertonicity of the muscles of the maxillofacial region can be chronic stressful loads associated with hazardous working conditions. However, this section of functional dentistry has not been sufficiently studied in relation to workers in hazardous industries. It is required to compare the results of electromyography of the muscles of the maxillofacial region and the data of psychological examination of workers. The aim of the study is to compare the psychological characteristics and the results of electromyography of the muscles of the maxillofacial region in workers with hazardous working conditions and normal working conditions in the 45-55 age group. Material and Methods: A comparative analysis of electromyography data of masticatory and temporal muscles, "Hamburg testing" of the masticatory apparatus and psychological characteristics was carried out in 50 workers of hazardous industries (radiation production factor) and in 53 workers in normal working conditions. Results of the study: the study revealed differences in the results of psychophysiological examination, "Hamburg testing" of the chewing apparatus and electromyography of the muscles of the maxillofacial region in workers with hazardous working conditions and working in normal conditions. Employees of hazardous industries, according to psychological examination, are subject to chronic stress, which leads to a distortion of the tone of the muscles of the maxillofacial region, which, in turn, causes more frequent detection of dysfunction of the masticatory apparatus in workers. Conclusion: the results of the study should be taken into account in the complex dental rehabilitation of workers in hazardous industries, including measures aimed at normalizing the muscle tone of the maxillofacial region.

The Impact

Research objective - assessment of the impact of working conditions and work experience on the quality of life of furniture production workers. Materials and methods. The assessment of the quality of life of 208 employees of the furniture factory "Maria" under various conditions of the production environment was carried out. The analysis of quality of life indicators for all scales of the SF-36 questionnaire took into account work experience and class of working conditions. Results. When assessing the quality of life of employees of a furniture production company, it is established that the quality of life depends on the class of working conditions. There was a significant decrease in quality of life indicators for those working in harmful working conditions corresponding to class 3.1, according to the SF-36 questionnaire scales responsible for mental health (social functioning, emotional functioning, mental health). When working in harmful working conditions, classified as class 3.2, these indicators tended to decrease not only on the scales of the SF-36 questionnaire, which are responsible for mental health, but also for the physical state of the body (role functioning, General health). At the same time, the dependence of quality of life indicators on the length of service in certain conditions of the labor process was studied. Thus, in the first two years of working in harmful working conditions (class 3.1, 3.2), there was no decrease in the quality of life of furniture production workers. However, when working for more than two years in similar working conditions, there was a significant decrease in the values of indicators of the quality of life of the subjects. Conclusions. It is proved that the longer the work experience in unfavorable working conditions, the lower the quality of life of furniture production workers.Noise as the main production factor in furniture factories, which leads to a decrease in the quality of life.

Chronic Mercury Intoxication

Introduction. Despite the apparent connection of the existing neurological disorders and changes in the psycho-emotional sphere with sleep disorders in patients with chronic mercury intoxication (CRI), these relationships remain the least studied in the clinic neurointoxications. The study aimed to establish a connection between neurophysiological, biochemical, and psychopathological indicators in patients with occupational chronic mercury intoxication and insomnia. Materials and methods. Thirty-six patients took part in the examination in the remote period of CRI. The average age of patients in this group was 50.7±1.05 years, with an average work experience of 14.7±1.05. The authors carried out a psychological examination to determine the levels of depression, anxiety, asthenic state, computed electroencephalography (EEG), cognitive evoked potentials (CEP), polysomnography, the level of neurotransmitters. Results. The study showed that asthenization, when exposed to mercury, occurs due to a decrease in the limbic-hypothalamo-reticular complex activity (the presence of equivalent dipole sources of pathological activity in the area of diencephalic formations (thalamus, hypothalamus) in 56.2±5.6% of cases. The study showed a decrease in activity cerebral cortex, confirmed by weakening the coherent connections of the α-range in the occipital, central and frontal leads according to the data of coherent EEG analysis and changes on the part of the CEP. There was a direct correlation between the level of total sleep time and the serotonin level (rs=0.45), an inverse relationship between the level of depression and histamine level (rs=-0.56). Conclusion. The studies carried out to make it possible to establish the mechanisms of insomnia disorders in chronic mercury intoxication, which cause a weakening of the tone of the cerebral cortex and changes in neurotransmitter metabolism, as well as disorders of the reticular system with limbic structures. The study showed a close direct relationship between neurophysiological, psychological, and biochemical parameters in implementing insomnia in patients with chronic mercury intoxication.

Introduction. The profession of “machine operator in metalworking”, one of the most common professions in various industries, characterized by a large volume of abrasive operations, accompanied by dust formation, which creates a potential for the occurrence of diseases of the visual organ.The aim of the study is to provide a hygienic assessment of working conditions and occupational risk of visual organ pathology in metalworking machine operators.Materials and methods. Observation groups — machine operators for metalworking of two training groups (experience up to 5 years, experience of 6–20 years). Two comparison groups (administrative and technical personnel of the enterprise) are formed according to the same age-experience principle.Results. The working conditions of machine operators were classified as class 3.2. taking into account the severity and intensity of the work process and the noise level (80 dBA) in the workplace. Nitrogen oxide, carbon monoxide, and manganese were registered in the air of the working area in concentrations below the permissible concentration (PC), and the aerosol dihydroxide was registered above the PC in 25.8% of cases. In the main working groups, diseases of the anterior segment of the eye were more often registered, among which dry eye syndrome (DYS) prevailed (94.1%), chronic blepharoconjunctivitis (79.9%), persistent corneal opacification (21.7%). There was an increase in the prevalence of detected diseases with an increase in work experience (p≤0.05). In machine operators, the frequency of inhibition of lacrimal formation and decreased stability of the tear film was recorded significantly more often, with increasing work experience, the degree of violation of lacrimal formation and stability of the tear film increased. The chances of detecting pathology of the anterior segment of the eye in machine operators are 5.9 and 3.5 times higher than in the comparison group. There are different forces of connection, increasing with the increase of work experience in the profession, between the working conditions of machine operators and the occurrence of SHG (relatively strong), with chronic blepharoconjunctivitis and persistent corneal opacity (medium strength), which suggests the professional conditionality of this pathology.Conclusions. The results obtained suggest that the pathology of the anterior segment of the eye is professionally conditioned in metalworking machine operators and necessitate the introduction of preventive measures aimed at protecting the visual organ.

Abstract: Working conditions at metallurgical enterprises are characterized by the impact of a complex of harmful production factors that do not correspond to the normalized levels, which causes the risk of developing professional and professionally conditioned pathology. Trained workers who are exposed for a long time to industrial noise that exceeds the permissible values by 10 dB or more are considered as a risk group for the development of aural (sensorineural hearing loss, SHT) and extraaural (high blood pressure, HBP) pathology. Hearing loss is an important medical and social problem, as it turns into a cognitive dissonance and a violation of verbal communication for the employee. Working conditions at one of the modern metallurgical plants were evaluated according to the data of sanitary and hygienic characteristics of working conditions. The study of the prevalence of SHT and HBP was carried out based on the materials of a medical examination and a questionnaire survey of workers (n=73, male, aged 36-75 years (57.32±0.89), with work experience of 8-58 years (34.29±1.16)). To assess the joint influence of age and seniority, an original scoring system was used, which allowed us to distinguish 3 observation groups. The severity of SHT and HBP was also assessed in points. The study showed a significant increase in the prevalence and severity of hearing loss and HBP with an increase in the duration of exposure and the age of employees. The presence of a close relationship between the analyzed pathology and working conditions is illustrated by the value of the odds ratio in groups 1-3 (ORSHT = 3.75-4.71; ORHBP = 2.0-5.0). Thus, the studied professional group of trained qualified metallurgists needs to develop health-improving measures to preserve labor longevity.

Harmful Effects

In accordance with the existing Federal sanitary standards, noise and infrasound are considered to be an harmful production factor and in terms of their prevalence they occupy a leading place in the national economy. To prevent the harmful effects of noise and infrasound on the health of members of the armed forces establishes the main lines. For prognostic assessment of harmful influence of production factors on production facilities and transport the special assessment of working conditions is carried out without fail. Hygienic research of workplaces has shown that noise and infra-sound levels correspond to harmful and dangerous classes, that is, risks of professional pathology of acoustic Genesis are created. The presence of acoustic sources in the Armed forces requires constant monitoring of them, the annual special assessment of working conditions development of preventive measures. The impact of noise and infra-sound leads to a decrease in military and professional performance and an increase in General and professional morbidity. The leading place in the structure of morbidity of noise etiology is a sensorineural hearing loss. This requires further improvement of the provision of specialized assistance to military personnel in the presence of noise hearing loss. In the current regulations of the military medical services noise and infrasound are not identified as a harmful factor, and therefore not fully developed the issues of professional selection, monitoring and medical examination of noise pathology. An important place in the system of prevention of harmful effects of noise is given to the means especially individual of protection against noise. Their absence and low efficiency pose a threat to the acoustic safety of military personnel. Provision of personnel with means of individual protection against noise and control of the correctness of their operation are the most relevant measures to reduce the noise pathology of the hearing organ. The existing system of measures to combat the harmful effects of noise in the Armed forces requires revision in accordance with the existing state legislative and legal framework.

Introduction.High levels of occupational incidence in coal miners of the Kemerovo Region determine the need to optimize the State Committ ee for Sanitary and Epidemiological Oversight for in-depth study of risk factors and planning of medical and preventive measures.The aim of the studyis to optimize the activities of the State Committ ee for Sanitary and Epidemiological Oversight in the planning of supervisory and sanitary measures aimed at reducing the level of OD in the coal industry.Materials and methods.On the basis of a sample of materials from the database of the Department of State Committ ee for Sanitary and Epidemiological Oversight in the Kemerovo Region on the occupational morbidity of miners for 2008–2016, the analysis of data on working conditions, age, experience, dynamics of occupational morbidity. Th e information on 7515 cases of occupational diseases in workers of coal mining enterprises is analyzed.Results.Indicators of occupational disease in the miners of the Kemerovo Region are higher than the national level, amounting to 13.23 per 10 thousand of the employed population. Employees of the main professions of the coal industry are particularly susceptible to occupational diseases: sinkers, miners of treatment faces, machinists of mining excavation machines, underground electric locksmiths, drivers of heavy vehicles, drivers of excavators and bulldozers. The reasons for the formation of occupational diseases in miners are unfavorable working conditions: physical overload, dust and gas contamination, noise and vibration, high humidity of the working area at low temperatures. Occupational diseases are more commonly diagnosed in workers aged 41 to 50 years (28.01%) and 51 to 60 years (69.23%). Th e most at risk of occupational disease are those working in contact with the harmful production factor for 21–30 years (60.5%) and from 31 to 40 years (26.1%).Conclusions. The results of the study are necessary for the rational planning of control measures and reasoned conclusions in the preparation of sanitary and hygienic characteristics of working conditions with suspicion of occupational diseases.
