[Comorbid state in coal miners suffering from lumbosacral radiculopathy].

The authors considered topics of occupational and general comorbidity of occupational lumbosacral radiculopathy in coal miners (2791 examinees) observed over 1976-2014 in occupational center. In patients having lumbosacral radiculopathy without occupational mixed diseases, the occupational disease was diagnosed at the age 3-5 years younger, and 2-4 years earlier from primary visit. Analysis of occurrence of general comorbid conditions with lumbosacral radiculopathy revealed some regularities: patients manifested with symptoms due to vibration have more frequent arterial hypertension than in those with lumbalgia, whereas in risk group of hearing affected by noise IHD was more possible.

[Contemporary organization of occupational medical service].

The article deals with state of occupational morbidity and principles of occupational medical service organization in Rostov region. The authors justify necessity to create medical rehabilitation departments in occupational pathology centers, partially financed by RF Social Security Fund.

[Mortality parameters of patients with occupational diseases and evaluation of medical care quality].

The authors analyzed mortality parameters among occupational disease patients in coal industry over 1968- 2014 (9271 cases). Findings are significant increase in age and length of service in workers first registered in occupational pathology center, and 6-fold decrease of life span from occupational disease diagnosis till death. The authors necessitate specification and implementation of follow-up procedure in workers with high occupational risk-and in occupational diseases patients, and complex medical rehabilitation for individuals with primary stage of occupational diseases.

[Factors forecasting risk of lumbosacral radiculopathy and comorbid diseases development in coal miners].

The authors constructed forecasting models of risk for occupational lumbosacral radiculopathy combined with vibration disease and occupational neurosensory deafness in coal miners suffering from lower back pain and signs of occupational hazards influence on health state. Scientific basis covered determination of high and low risk groups for health disorders in miners, according to calculations within suggested formula in forecasting models. Findings are that each year following primary diagnosis of lower back pain and signs of occupational hazards influence on health state, probability of occupational lumbosacral radiculopathy combined with vibration disease increased by-1S% (OR = 1.15 1; 95% CI = 1.105-1.200), combined with occupational neurosensory deafness - by 5% (OR = 1.054, 95% CI = 1.097- 1.507). Probability to get occupational neurosensory deafness combined with occupational lumbosacral radiculopathy was maximal in miners aged 30-39, and combination of vibration disease and radiculopathy was more frequent in miners aged 40-49 (OR = 1.542; 95% CI = 1.154-2.062).

[Evaluation of workers' periodic medical examinations quality].

The results of the study to evaluate satisfaction with the quality of the periodic medical examinations of workers (PME) are analyzed. In survey 45 employers, 120 doctors performing PME and 107 workers participated. The results show low satisfaction with the quality of the PME. Employers in 60% of cases noted the formal conduct of PME. Doctors in 40.8% of cases as the main defect in the organization of PME mentioned the lack of quality control system. According to the workers' opinion, the poor quality of PME recognized in 30.8% of cases; however, 54.2% of the workers noted the good organization of the PME.

[Follow-up in coal miners suffering from lumbo-sacral radiculopathy].

The results of a retrospective dynamic monitoring in 1976-2014 of the workers of coal mines of main (n = 1732) and auxiliary (n = 1059) occupations, with diagnosed occupational sciatica (OS) in the center of occupational medicineare viewed. It was found that the workers of the main occupationson average of 3 years earlier than initially treated at the center of occupational medicine, and occupational disease OS sets for them 1.5-2 years earlier. The analysis of the formation of risk groups depending on the diagnosis and treatment of the primary analysis of the incidence of OS.

[Indicators and criteria of the assessment of quality of medical examinations of workers].

The results of periodic medical examinations (PME) of workers of the machine-building enterprise are analyzed and factors defining their quality are considered. The criteria of PME quality are proposed and used along with analysis of the defects of medical records. With help of Pareto chart the most significant factors affecting the quality of PME are revealed. These were noted in 76% of cases and included: lack of expertise of fitness to work, the discrepancy of the results of this expertise and the worker's pathology, the lack of registration and collection of complaints and anamnesis.
