Título Somatosensory evoked potentials in workers exposed to toluene and styrene
Información bibliográfica June 1993, Vol.50, No.6, p.520-527. Illus. 47 ref.
Resumen Somatosensory evoked potentials (SEPs) were used to evaluate possible subclinical impairment of the nervous system in 36 rotogravure printers with severe exposure to toluene, 20 workers with severe exposure to styrene in a glass laminate manufacturing plant, and a comparison group of healthy subjects. Exposure was estimated by measurements of toluene and styrene in breathing zone air, hippuric acid in urine in the group exposed to toluene, and urinary mandelic acid in the group exposed to styrene. Peripheral conduction velocities in the arm and leg, and central conduction time after tibial nerve stimulation were decreased in both exposed groups. Prolonged latencies of peripheral and cortical SEPs were found in workers exposed to styrene. Some abnormalities in SEP's at peripheral or spinal and cortical levels were found in both groups. A trend toward increased frequency of abnormal SEPs with duration of exposure of toluene and styrene and alcohol abuse was found. Abnormalities in SEPs in the exposed groups are most probably of multifactorial origin. Central SEP abnormalities in both exposed groups could indicate early signs of subclinical dysfunction at spinal and cortical levels and could be due to toluene or styrene exposure, probably potentiated by alcohol consumption in the group exposed to toluene.
