[Clinical interpretation of the effects of leading hazardous factor in multifactorial intensive action].

The article "Clinical manifestations of chronic exposure of metallurgists and blacksmiths to heating microclimate" by T.K. Semennikova et al., published in "Industrial medicine and occupational hygiene" No 5, 1992, was reviewed and compared with the author's data. Extensive clinical materials in the article reviewed are traced only to chronic overheating, however the hygienic data presented prove critical levels of noise, local and general vibration, hard work. Index of occupational diseases was calculated, so vibro-acoustic effects and chronic overheating appeared to be comparable. Analysis of etiology and pathogenesis appeared to play an important role in evaluation of effects caused by multiple critical factors.
