title: [Various aspects of the clinical and electroencephalographic studies in workers chronically exposed to vinyl chloride].
abstract: The paper presents evaluation of the nervous system and bioelectric functioning of the brain (EEG) in 114 workers aged 20-62, employed in significant exposure to vinyl chloride for 1-28 years, on average--7.5 +/- 4.0. Clinical symptoms of the nervous system occurred in form of peripheral--vegetative syndrome with accompanying vasomotor disturbances of Raynaud syndrome type EEG yielded 39 (34,2%) correct and 75 (65,8%) incorrect records. Among incorrect records most frequent (32.5%) were low-voltage and flat records; of this--those with fast spindled activity and frequent changes typical for reduced wakefulness. The nature of clinical symptoms and EEG disturbances may point to the contribution of hypothalamus in the pathomechanism of changes in those chronically exposed to vinyl chloride.
