Complex descriptive, physiologic and hygienic studies covered various occupational groups of physical and mental work and revealed that health disorders probability depends on intensity of occupational factors. Increase in the intensity results in higher physiologic expenditure and greater incidence of occupational diseases. Symptoms of disorders appeared to depend on specificity of occupational factors.
The study covered influence of occupational factors on health state in 2 groups of workers engaged into facing (59 plasterers and 74 house painters) and matched in age, sex and length of service. Work of plasterers and house painters appeared to encounter risk of occupational sensomotor system disorders specified not only by type and hardness, but also prevalent direction of local muscular load.
The article covers literary data and observations concerning influence of occupational factors and working environment on workers' reproductive health. The authors stress common ground of pathogenetic mechanisms underlying pathomorphosis of reproductive disorders and other symptoms caused by occupational exposure. The materials emphasize importance of reproductivity studies in workers exposed to occupational hazards, as reproductive disorders are early and gentle signs of inner imbalance.
The authors demonstrated that work of female molders, acquisitors and stacking packers is characterized by physical load, great number of cliched manual movements, intensive inclinations of corpse and constrained working posture. Prolonged exposure to unfavorable occupational factors results in neuromuscular and cardiovascular stress that induces pathologic changes with increasing length of service. Complex of prophylactic measures suggested by the authors proves effective as releases working strain and delays fatigue during the working shift.
Extensive data covering 2086 examinees served for analysis of peripheral vascular, locomotion, neurologic disorders developing at various stages of adaptation process in workers engaged into mining in the North. Unfavorable general and local cooling resulted in overstrain of thermoregulation mechanisms, caused lower performance, difficulties in adequate occupational functioning, early formation of diseases. Association of cooling and intensive vibration with significant physical load induced neurovascular and neurodystrophic changes being a result of both local microcirculation disturbances and disordered regulation of peripheral vascular tone, higher excitability of vasoconstrictors stimulated by central mechanisms.
Complex clinical and physiologic examination covered operators facing changeable psychoemotional strain at work. The degree of psychoemotional strain appeared to have strong correlation with the diagnosed neurosis rate. The examination revealed main clinical syndrome in the neuroses and proved a distinct trend that prolonged forms of the condition were prevalent in the groups engaged into more emotionally burdensome work. The data obtained require further investigation to elaborate optimum measures for prophylaxis and treatment of the diseases diagnosed.
Clinical and hygienic studies covered agricultural machine operators, bulldozer operators, truck drivers, excavator and boring machine operators, display terminal controllers, electronic miniature device assemblers. The studies proved that occupational hazards (general vibration, sitting posture) result in formation of vertebral neurologic disorders in the examinees. The localization and clinical manifestations appeared to depend on intensity and site of the acting hazard.
The clinico-functional examination of agricultural machine-operators, truck drivers, excavator and boring machine operators revealed that, under low-frequency general vibration, polymorphic pathologic changes occur in human organism. Those include peripheral vascular and neuritic disorders and changes in the vertebral column. The most peculiar symptoms of VD are dealt with. The data obtained show to the importance of further elaboration of differential diagnostic criteria of VD, specifying its pathogenic mechanisms and prevention measures working out.
The paper is concerned with the results of many year-old clinical studies on workers of vibration-risk and "noisy" professions. The authors consider occupational and biomedical risk factors contributing to the development of vibratory disorders and noisy cochlear neuritis, the main clinical syndromes of this occupational pathology, modern methods of their preclinical and early clinical diagnosis. The basic principles of differentiated follow-up and combined prevention as well as problems of therapy, medical labor examination and rehabilitation of patients with vibratory disease and occupational cochlear neuritis are described.
