The problem of preventing and reducing the level of occupational morbidity among agricultural workers is of particular importance, since occupational diseases are the cause of high disability and mortality rates of the working-age population all over the world. As a research task, the authors made an attempt to identify the features of the interdependence of the components of self-awareness and conflicts in value orientations for the manifestation of the phenomenology of disorders with further designation of the targets of psychotherapy. An experimental psychological study which included 40 agricultural workers with occupational diseases of the peripheral nervous system (experimental group) and without diseases (control group) was carried out using the multilevel personality questionnaire «Adaptability», the self-attitude test questionnaire by V.V. Stolin and S.R. Panteleev, and Schwartz's methodology «Value orientations». As a result of the study, it was found that in the subjects of the experimental group, in contrast to healthy individuals, the hyposthenic type of response prevails, there is the average level of neuropsychic tension, there is no tendency to reactions of the impulsive type, and a high negative and statistically significant relationship between the indicator of conflict in values and the level of personal adaptive potential is identified. The results of the study indicate that among agricultural workers with occupational diseases of the peripheral nervous system, accentuations of the character of the «inhibited» circle prevail, there is an increased level of anxiety and low tolerance to unfavorable factors of professional activity. The dominant personal values at the level of convictions are personal success in accordance with social standards and enjoyment of life, and at the level of behavior — understanding and protecting the well-being of all people and nature, preserving and increasing the well-being of loved ones. With an increase in conflict in value orientations, the adaptive potential of the respondents decreases, and a decrease in the level of self-attitude entails a decrease in adaptation.

Abstract Background The clothing industry is traditionally well developed branch of industry in Bulgaria Harmful factors of manufacture are forced posture, monotonous work, noise, vibration, poisons etc. At the beginning of 2016, the persons directly employed in the sector add up to 92 000, representing 6% of the employees in Bulgaria. An impairment of musculoskeletal and peripheral nervous system is frequent among these people in relation with the exposure of their professional experience. The aim of the study is to observe the influence of occupational diseases in clothing industry on social and emotional wellbeing of the employees. Methods For the purposes of the study, 103 persons employed in clothing industry, with impairments of the musculoskeletal system and the peripheral nervous system, were investigated. They were admitted to the Department of Occupational Diseases, of the University Hospital in Pleven during the period 2014-2017. Data were collected by interview, documents review and clinical examination. Results Analysis of the results revealed a statistically significant inverse association between performance of daily life activities and length of exposure of patients (p < 0.05). This means that increasing length of exposure restrict the abilities of the investigated persons to perform daily life activities. About 62% of the respondents are often and long standing patients, with more than 4 cases of hospitalization and over 30 days of disability per year. In 68% of the subjects the average duration of one illness exceeds 10 days. Long period of disability affect their income, working position and family relationships. More than a half of people surveyed (56%) cannot afford the recommended rehabilitation which retards the process of recovering. All these facts affect their mood and health self-esteem. Concussion Occupational diseases in clothing industry affect quality of life, social and professional performance of the employees. Key messages In clothing industry many risk factors affect workers’ health. There is a significant association between length of occupational experience in this branch and social aspects of occupational diseases. Occupational diseases in clothing industry affect capability of work and daily routines of employees. They have been associated with long and expensive period treatment and rehabilitation.

Introduction. Laser radiation, discovered in the mid-twentieth century, is actively used in modern medicine. Along with the effects of high-energy lasers, researchers are attracting more and more attention to the methods of low-intensity laser therapy in the treatment of various diseases of the peripheral nervous system. At the same time, there are very few works in which the effectiveness of low-intensity laser radiation action in occupational diseases of the nervous system would be assessed.The aim of study was searching for information on the modern understanding of the mechanisms of action of low-intensity laser radiation and on its use in the treatment of occupational diseases of the nervous system in Russian and foreign scientific literature.Materials and methods: The article presents an overview of available scientific Russian and foreign literary sources. Search and selection of sources was carried out using open databases PubMed and RSCI.Results. Low-intensity laser therapy has anti-inflammatory, analgesic, immunocorrective and reflexogenic effects. There are described cases of successful application of low-intensity laser radiation in the treatment of vibration disease, radicular and muscular tonic syndromes, carpal tunnel syndrome. At the same time, there are no works in which the influence of low-intensity laser radiation on the dynamics of professional polyneuropathy of the upper limbs would be assessed.Conclusions: The biological effect of low-intensity laser radiation is complex and many-sided. Low-intensity laser therapy has a wide spectrum of action on various pathogenesis pathways, it is a common method of treating diseases of the peripheral nervous system, including professional aetiology. The urgent task is to substantiate and develop a technique for using low-intensity laser radiation to treat patients with professional polyneuropathies of the upper limbs (as the most common occupational disease of the peripheral nervous system) and to evaluate its effectiveness during dynamic observation.

The Republic

According to Rosstat forecasts for the period up to 2026, in the next 15–20 years, the population will decrease due to a decrease in the number of people of working age due to a low birth rate, a high death rate of the working-age population, an increase in morbidity and disability. One of the most common diseases among employees is the peripheral nervous system, which is detected in 32.3–58.0% of the surveyed employees of industrial enterprises. They make up 55.7–66.0% of the total occupational morbidity.The purpose of the study is to assess the degree of professional disability in occupational diseases of the peripheral nervous system. The analysis of occupational diseases of the peripheral nervous system for the years 2015–2017, its structure on the materials of the Occupational Medicine Centre of the Republic and the results of their primary medical and social examination (MSE) according to the acts of examination the national Bureau of MSE to assess the occupational disability in occupational diseases of the peripheral nervous system.It was found that in 2015–2017, the average level of occupational morbidity due to diseases of the peripheral nervous system was 0.54 per 10 thousand working population of the Republic. The most frequent are sciatica of the lumbosacral level–0.29 o / o, which occupy more than half (53.4%) of the total occupational morbidity due to diseases of the peripheral nervous system. Occupational diseases of the peripheral nervous system were detected in the machine-building, metallurgical, mining, agricultural, oil-producing and construction sectors of the economy. Almost all (93.9 per cent) who applied to Bureau of MSE was installed, the percentage of occupational disability for a period of one year. The vast majority (73.2%) of those who applied to the MSE office found 30% loss of professional ability to work. In the year of establishment of an occupational disease, 65.0% of professional patients are referred to the Bureau of medical and social expertise (MSE). They continue to work at their previous workplace and are exposed to the same harmful and dangerous working conditions.Effective prevention of occupational diseases and labor losses from them requires building an integrated system that combines primary, secondary and tertiary measures (rehabilitation by individual program) of prevention with the development of clear measures of responsibility for all those interested in a healthy employee.

Introduction. The article presents the results of a study of working conditions and the health status of patients with occupational polyneuropathy (PNP) of the upper limbs. Such a clinical and hygienic assessment of people with occupational PNP contributes to the optimal examination and treatment of patients with the preliminary diagnosis who are referred to occupational pathology centers.Material and methods. The study included 236 patients of two main occupations (painters-plasterers and miners): 113 women and 123 men. Results. The average age of patients at the time of the examination was: for painters-plasterers (women) - 55.5 ± 5.7 years, for miners (men) - 53.9 ± 6.3 years. Work experience of patients with physical overload at the time of diagnosis of occupational PNP accounted for plasterers - 25.1 ± 8.0 years, for miners - 20.4 ± 6.7 years. Working conditions of plasterers and miners were revealed to contribute to the development of occupational diseases of the peripheral nervous system and musculoskeletal system from the effects of physical overload and functional overstrain of the muscles of the upper extremities. Most often occupational PNP of the upper limbs is accompanied by the parallel development of professional chronic shoulder-scapular periarthrosis, epicondylosis, myofibrosis of the forearms, and shoulder girdle (a complex of occupational pathology of the «working hand»); radiculopathy of the cervical and lumbosacral levels.Conclusions. The main common harmful factor in the examined patients is the severity of the labor process. In less than one-fourth of the examined patients (15,7%) occupational PNP of the upper limbs was the only occupational disease. In other cases, its development was accompanied by the appearance of other occupational diseases of the peripheral nervous system and the musculoskeletal system. Patients referred to the examination in occupational pathology centers with a diagnosis of “PNP of the upper extremities” need a comprehensive examination to verify a possible complex of occupational pathology.

Study Results

Introduction. Multiple studies of health state of workers in various economic branches of Russia revealed that peripheral nervous system diseases are among the most prevalent disorders. Th eir prevalence varies from 32.3 to 58 diseases per 100 examined workers, and they occupy usually fi rst place in the morbidity structure. Th ey are leaders among occupational diseases also. Objective. To determine features of occupational morbidity with peripheral nervous system diseases and its structure among workers in various economic branches of Bashkortostan Republic. Materials and methods. Th orough analysis covered occupational morbidity with peripheral nervous system diseases by separate branches, workers who are directly exposed to occupational hazards. Specifi c levels of the morbidity are defi ned by occupations, length of service in each economic branch. Results. Over 100 cases of occupational diseases are annually registered in Bashkortostan Republic. Over a half of them (54%) are diseases of peripheral nervous system. Th eir share among all occupational diseases tends to increase. Th e most prevalent type of peripheral nervous system diseases are radiculopathy (0.29 cases) and vibration disease (0.14 cases per 10,000 workers). Nearly all occupational diseases of peripheral nervous system are diagnosed in machinery building, metallurgic, mining, oil extracting industries, agriculture and building industry. In these economic branches, average of 16.59 cases per 10,000 workers exposed to occupational hazards is assigned to occupational peripheral nervous system diseases. Occupational diseases of peripheral nervous system diagnosed at average length of service of 23,3±3,4 years. Th e study results helped to determine specifi c economic branches associated with peripheral nervous system disorders development. At the highest risk of peripheral nervous system disorders are workers of mining (20,8‰0) and metallurgic (10,6‰0) industries. Conclusions. Peripheral nervous system diseases are the main causes of occupational morbidity, detailed according to specifi c economic branches and occupational groups, should be a basis of particular measures on lower impact of occupational risk factors, on prevention, health preservation, occupational and medical rehabilitation of the diseased.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.

Abstract Lesions of the peripheral nervous system (PNS), whether due to injury or illness, commonly result in residual symptoms and signs and, hence, permanent impairment. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides) describes procedures for rating upper extremity neural deficits in Chapter 3, The Musculoskeletal System, section 3.1k; Chapter 4, The Nervous System, section 4.4 provides additional information and an example. The AMA Guides also divides PNS deficits into sensory and motor and includes pain within the former. The impairment estimates take into account typical manifestations such as limited motion, atrophy, and reflex, trophic, and vasomotor deficits. Lesions of the peripheral nervous system may result in diminished sensation (anesthesia or hypesthesia), abnormal sensation (dysesthesia or paresthesia), or increased sensation (hyperesthesia). Lesions of motor nerves can result in weakness or paralysis of the muscles innervated. Spinal nerve deficits are identified by sensory loss or pain in the dermatome or weakness in the myotome supplied. The steps in estimating brachial plexus impairment are similar to those for spinal and peripheral nerves. Evaluators should take care not to rate the same impairment twice, eg, rating weakness resulting from a peripheral nerve injury and the joss of joint motion due to that weakness.
