Pain tolerance was assessed in 44 volunteers by the analysis of their reports during blood collection using a 12-point verbal rating scale. Thereafter, pain intensity in response to 5 successive pricks was measured with a mechanical algesimeter, and the participants of the study were asked to evaluate pain sensation based on a 0-100 score visual-analogous scale. The test was discontinued as soon as a patient reported painful feeling in excess of 50 scores. ⋯ It was shown that the results of self-evaluation of painful sensation based on the verbal rating scale correlated with the number of tolerated test challenges. There was no significant correlation between the described signs. It is concluded that the methods for the assessment of pain tolerance described in this paper make it possible to predict the behaviour of a group as a whole but not of individual subjects.

Comparative Study[Occupational loss of hearing in the workers employed in the railroad transportation].
The prevalence of occupational deafness and factors contributing to its development are considered in the context of the present-day structure and causes of hearing disturbances in the subjects employed in railway transportation occupations. Special emphasis is laid on expert examination of their professional suitability. ⋯ Specific features of this pathology are considered with reference to the patients' age and duration of occupation in the railroad sector. Drawbacks in organization of periodic prophylactic medical examination are analysed; the most challenging tasks for the development of preventive measures against negative effects of occupational noise on the subjects employed in the railroad sector are discussed.
