[The medical social measurements of conditions of professional activity of vegetable-growers of protected soil].

The working conditions in hothouse farming, medical social possibilities and limitations of prospects of professional longevity affect quality of life of employees and their family members, influencing development of state policy in health care, occupational safety and employment. The article identifies and describes, on the basis of sociological quantitative and qualitative methodology, medical and social problems of modern greenhouse farming. The quality of medical support in this professional field is assessed. The main factors of shortening of length of professional experience are established. The conclusions are made that professional resources of protected soil vegetable-growers are characterized by lacking of special education that to a certain degree is compensated by acquired long-term work experience. The main factors obstructing involvement of employees in this profession are physically hard labor and inconvenient operating conditions. The medical support of professional and labor practices in greenhouse farms is as rule only formal. Prevention and treatment of acquired diseases is implemented mainly in home conditions, in polyclinics of place of residence and in private medical organizations at the employees' own expense. The professional longevity does not cover retirement age by reason of debilitated health because of unhealthy working conditions and wide spectrum of acquired diseases.

["The effect of healthy worker" in various areas of occupational medicine: the publications review].

The article considers "the effect of healthy worker" as a source of systematic errors that makes epidemiological studies in occupational medicine less reliable and this is a significant problem. It is very important to analyze the professions and work conditions under which the phenomenon of self-selection and artificial «health improvement¼ of working population is to be expected. The scientific publications from open databases and other sources, discussing effect of self-selection under various work conditions and in various professions were analyzed. The data related to effect of healthy worker during labor activity in conditions of contact with industrial dust, allergens, radiation, physical load is discussed. In development of self-selection, psycho-emotional intense work is of greatest importance. In many specialties, this effect plays an essential role in the formation of rate of arterial hypertension. The substantial staff turnover and self-selection are associated with shift and night work, disorders of sleep-wake rhythm in various specialties. The underestimation of the effect of healthy worker may result in underestimation of the degree of harmfulness of work. On the contrary, its analysis will permit to obtain more accurate data on the impact of occupational work conditions on human organism and to develop methods of professional selection and recommendations on diseases prevention.

[The prevalence of gastroesophageal reflux disease in agricultural workers].

Among agricultural workers is common gastroesophageal reflux disease. On a professional factors affecting agricultural labor (physical activity, weight lifting, carrying heavy loads, frequent and/or long slopes). These factors contribute to the development of gastroesophageal reflux disease and severe course.

[Bioethical aspects of epidemiologic research concerning occupational risk].

The author analysed peculiarities of ethic examination for occupational risk research in industrial medicine. Findings are that occupational risk research involving humans as examinees have significant social and individual value, therefore ethically justified. The article covers the most important points of the study design, possible sources of preference conflicts in industrial medicine. The study results are important for ethic committees, when considering the studies connected with examination of occupational populations.

[The use of cytoflavin for the treatment of chronic brucellosis].

Clinical and pathogenetic efficacy of cytoflavin as a component of combined therapy of chronic brucellosis was tested in 50 patients who repeated its beneficial effect on the quality of life. The mechanism of cytoflavin action consists of lowering severity of endogenous intoxication and systemic inflammation.

[Ethics and informing an employee on occupational risk].

Considering biologic ethics and information right, the authors justify necessary formation a system providing materials on occupational risks for employees in contemporary industry. Problems associated with collecting information materials cover linguistic aspect and difficulty in receiving reliable data on diseases prognosis meeting criteria of evidence-based medicine.

[Potential of ultrasound diagnostics of occupational scapulohumeral periarthrosis].

Quota of diseases traditionally assigned to "working hand pathologies" is increasing in occupational morbidity structure of various countries and industries. Term "habitual" or "cumulative traumatism" quite accurately shows mechanism of injury.

[External respiration parameters in workers engaged in synthetic detergents production].

The study covers results of thorough clinical and functional examination of workers engaged into contemporary chemical production. The authors studied effects caused in immunity parameters, respiratory organs and skin by sensitizing and irritating chemicals. Findings are that the most significant changes in external respiration parameters and high predisposition to respiratory diseases are associated with specific sensitizing to industrial allergen and with higher IgE levels.

[Percutaneous laser irradiation of blood in the treatment of hemodynamic disorders in patients with vibration disease]. / Chrezkozhnoe lazernoe obluchenie krovi v lechenii gemodinamicheskikh narushenii u bol'nykh s vibratsionnoi patologiei.

The article presents data on influence of percutaneous laser irradiation of blood on central and peripheral hemodynamics in 24 riveters facing vibration disease. Clinical improvement was seen in all the examinees. Rheography showed high efficiency of the method in the patients with initially increased vascular tone in hands (angiospastic syndrome), possible correction of disordered cerebral circulation.

[Etiology of hypertensive states in workers engaged in expedition shifted-duty brigades]. / Razvitie gipertenzivnykh sostoianii u rabochikh ékspeditsionno-vakhtovykh brigad.

The state of peripheral and central hemodynamics was examined in 603 workers engaged into shifted duty expeditions in West Siberia, considering the length of service in the shifted duty cycle. The examination revealed high occurrence of cardiovascular diseases with prevalent hypertension. Rheographic findings proved that in 5 years of the shifted duty work high blood pressure develops with increased peripheral vascular tone (especially in brain) and enhanced contractility of left ventricle. Important role in the high blood pressure formation is played by changes of hemodynamics in first days after the duty shift.
