The authors present data on occupational oncologic morbidity in Russia by federal districts and regions. Over 2002 2014, a total of 497 cases of occupational cancer was registered, that is less than 0,3% of minimal expected number of cases. Necessity is to urgent improvement of legislation and methodic basis, informational supply, providing qualitative account of occupational oncologic morbidity. Important role in solving this problem could be played by continued sanitary and hygienic certification of caricnogenically dangerous institutions in RF and creation of Federal register (governmental automated information system) of individuals who had (has) occupational exposure to carcinogenic factors.

The article covers analysis and systematization of major internet resources used to train high qualified professionals with higher medical education for competent and successful education of doctors in speciality 31.08.27 Diving medicine.

Occupational burnout syndrome - an important health risk factor - is seen not only in social occupations, but also in “subject-object” occupation professionals. Complex study of work conditions and health used VV. Boiko test for assessment of emotional burnout level in radio and television broadcasting center personnel. Considerable share (53,3%) of main occupations workers in radio and television broadcasting center demonstrates high level of occupational burnout (exhaustion phase has developed or is being developed). Median total points of occupational burnout syndrome equalled 123 (74,0; 155,0) that is higher than the similar parameter for many “subject-object” occupations. Emotional defence is manifested by withdrawal from emotional show at work, increased distance in communication with colleagues, at home with relatives, avoidance of work demanding emotional charge. Longer length of service is connected with less open emotions not only in occupational sphere, but outside profession with relatives, friends. The results obtained point to predisposition for lower performance and health disturbances, necessitate consideration of this factor in complex evaluation of work conditions and health of personnel engaged in radio and television communications.

In Russian Federation, absent regulation document for criteria and methods evaluating screening properties of protective means against radio frequency electromagnetic fields necessitates development of general principles and methods for indivual protective means testing. Findings are that indivual protective means testing are expedient with consideration of measurements in free space and evaluation of absorbed electromagnetic energy in tissue-equivalent phantoms. Screening coefficient should be assessed in several zones corresponding to location of human vital organs.

The authors studied influence of low frequency noise on cells genome and cell death processes. Vistar male rats were exposed to low frequency noise with maximal range up to 250 Hz with noise pressure of 120 dB or 150 dB once (during 17 minutes) or repeatedly (17 minutes 5 days per week over 13 weeks), after that frequency of chromosomal aberrations in bone marrow cells and serum low-molecular DNA were assessed. In comparison with reference values, single exposure to low frequency noise with noise pressure of 120 or 150 dB reliably increased frequency of chromosomal aberrations more than 10-fold and caused dicentrics in aberrations spectrum, significally increased serum low-molecular DNA over 7-fold, with low-molecular DNA level remaining high during 7 days after exposure to low frequency noise. Repeated exposure to low frequency noise with noise pressure 120 and 150 dB resulted in reliable increase of low-molecular DNA level 36-fold and 22-fold respectively vs. reference values. Thus, low frequency noise harms genome, with more frequency of chromosomal aberrations, and increases apoptosis that manifests in higher level of extracellular low-molecular DNA. Some part of the work was performed with governmental financial support of leading universities of Russian Federation (grant 074U01).

The article characterizes occupational factors including acoustic ones that influence work conditions of civil aircraft crew members, presents methodic basis to evaluate parameters of aviation noise inside cabin, with consideration of additional load from aviaheadsets. To specify scientifically based method for calculating acoustic load on civil aircraft crew members in cabins, the authors measured noise parameters inside cabins of aircrafts used at present in Russia, and noise-proof properties of domestic and foreign aviaheadsets. Normalized values suggested: equivalent level of A sound over a month (L_A,eq,m), over a year (L_A,eq,y); suggestions for reference values: equivalent level of A sound (L_A,eq,g), over an arbitrary period of piloting length (L_A,eq,T); coefficient of piloting load. Principles of these calculations are determined. The method is designed as an addition to sanitary rules and regulations 2.5.1.2423-08, determining hygienic requirements to work and rest conditions for civil aircraft pilots.

The article presents results of physiologic studies of nine occupational groups of migrants from south republics of Middle Asia to Moscow region of Russian Federation. The authors revealed features of cardiac rhythm regulation variability in the migrants in accordance with physical exertion value and psychoemotional characters of work. Optimization of the adaptation processes should get along with organization of rational work and rest schedule, healthy lifestyle formation, better medical service to the migrants.

The authors present results of X-ray examination of miners working incleaning mine face, subjected to complex of occupational hazards (dust aerosols, physical overexertion) among which local and combined occupational vibration could be the most important from the viewpoint of possible occupational osteopathy. Examinees were males: 60 ones with suspected vibration disease, 35 ones with diagnosed vibration disease (vegetative sensory polyneuropathy) stage 1 and 30 ones in reference group matched by age and length of service. For osteoporosis diagnosis (according to mineralization level in distal forearms), the authors evaluated possibilities of digital osteodensitometry standard in occupational therapy with digital low-dose X-ray devices.

The study covered lipid content of RBC membranes in divers exposed to extreme hyperbaric factors at work. Findings are that prophylactic intake of biologically active additive nutrient “Kalifen” made of viburnum berries preserved physiologic characteristics of RBC and recovery of lipid components in their membranes.

Prospective cohort observational study covered phenotypic features of COLD formed under influence of various occupational etiologic factors vs. COLD caused by tobacco smoking. The study included totally 170 COLD patients (2011 criteria of COLD). In accordance with exogenous etiologic factor, the authors selected examinees in 3 strata simultaneously: COLD due to toxico-chemical aerosols (n = 42), COLD due to inorganic dust (n = 55), COLD due to tobacco smoking (n = 73). Evaluation covered influence of ecologic and industrial conditions on main mainfestations of the disease. Statistic analysis: comparison of quantitative variables - Kruskal-WallisANOVA, quantitative variables - criteria c², influence of independent variable on the dependent one - single-factor and multi-factor regression, p = 0,05. For COLD due to toxico-chemical aerosol, characteristics are rare but severe exacerbations (total amount is 366/427 person-years, severe ones - 312/427 person-years), severe dyspnea (mMRC 2,5 ± 0,12 points), minimal decrease of FEV1 (65,7% ± 3,21%) and minimal speed of bronchial obstruction progress (decrease of FEV1 by 0,08 ml ± 0,006 ml per year), emphysema, pulmonary hypertension, low serum level of VEGFA. For COLD due to dust, characteristics were bronchial hyperreactivity (in 45% of patients), cough, rare severe exacerbations (total exacerbations 825/537 person-years, severe ones - 227/537 person-years), lower dyspnea intensity (mMRC 1,9 ± 0,13 points), concomitant interstitial fibrosis, «average» level of VEGFA.

Examination covered 245 individuals and included characteristics of endocrine state of pulp and paper plant workers over 2011-2012, in comparison with data from 1990, as well as comparison with reference groups of male workers with no contact with chemical industry in Arkhangelsk. Findings are both in main and reference groups general decrease in levels of cortisol, thyroxin, progesterone, testosterone, insulin, somatotropin and increased serum level of estradiol. With that, inside both groups, reliable tendencies to increased levels of cortisol, thyroxin, insulin, SSH and lower concentration of progesterone in the pulp and paper plant workers vs. the reference group members. Positive tendency was absence of abnormal concentrations of insulin, SSH and lower frequency of high cortisol levels in the pulp and paper plant workers nowadays.

Important role in treatment and prophylaxis for vibration disease due to local vibration is played by physical factors. If high frequency components prevalent in occupational vibration, treatment with electric therapy, laser, magnetic fields, lymphatic drainage, hydrotherapy provides influence on leading chains of systemic microangiopathies pathogenesis - dysbalance of regulation influences by vegetative nervous system, vasoconstriction and intravascular changes, vascular permeability and microcirculation disorders. If low frequency coomponents prevalent in occupational vibration, treatment of polyneuropathies and locomotory disorders incorporates trophic processes activation: transcranial electroanalgesia, surface application of mineral waters, manual and subwater massage, ozone therapy, local spark discharges, peloids. Complex use of physical methods also increases human adaptational resources.
