Title An electrophysiological follow up of patients with n-hexane polyneuropathy
Bibliographic information Jan. 1991, Vol.48, No.1, p.12-17. Illus. 17 ref.
Abstract Electroneurographic (ENeG) and evoked potential (EP) studies were regularly performed on 11 printing workers with n-hexane polyneuropathy after cessation of exposure. At the initial examination, the ENeG studies simulated a demyelinative process. Further slowing of nerve conduction velocity, or further decreasing of action potential amplitude, or both, in the follow up ENeG study were found in about half the patients. After the patients had regained full motor capability, conduction velocities in motor nerves were still significantly slowed. These ENeG characteristics correlate with the pathological and pathophysiological changes in experimental hexacarbon neuropathies. The initial findings from the EP studies indicated a conduction abnormality in the central nervous system (CNS). Residual abnormalities were also found in the interpeak latency of auditory EPs in the brainstem and in the absolute latency of scalp somatosensory EPs from the peroneal nerve. Astroglial proliferation in the CNS probably impedes recovery of the abnormalities in EP.
