Two cases of Morvan's chorea are reported. One of the patients presented the characteristic of having had two attacks, the first after organic mercury preparations, and the second after gold salts for inflammatory rheumatism. The second case had facial fibrillations only, and this was followed by a regressive polyradiculoneuritis one month later. This latter case raises certain diagnostic problems. The existence of a particular type of immuno-allergic tendency could be validly related to a triggering effect of various etiological agents (metals such as mercury or gold salts, or infective agents). The absence of hypotonia, and a regressive course appear to be the characteristics that distinguish fibrillary chorea from the continuous activity syndrome of the muscle fibers described by Isaacs.

This study investigates the long-term neuropsychiatric manifestations of single or combined chemicals: manganese; zinc phosphide; lead, mercury, and TNT; and pesticides among exposed industrial workers. We found that 75% of the exposed subjects as a whole and 50% of those exposed to each of Zinc phosphide and pesticides presented with more than one neuropsychiatric symptoms or signs. The main signs were mask faces, hyporeflexia, hyperreflexia, peripheral neuropathy, static tremors, radiculopathy, muscle weakness, mental changes, fasciculations and tremors, wasting, hypotonia, abnormal deep reflexes, and sensory hyposthesia. Neurological manifestations were confirmed by electromyography and their severity was related to the duration of exposure and confirmed as well by electroencephalography. These results are discussed and their implications high-lighted.

The human cerebellum is composed of 2 hemispheres and a narrow medial section (vermis). Three pairs of dense fiber bundles (peduncles) connect the cerebellum to the brain. The cerebellum possesses widespread outgoing connections. Insult can result in neurologic deficits, including ataxia, hypotonia, dysarthria, and ocular motility problems. It is particularly susceptible to toxic effects of metabolic and medicinal insults. The cerebellum is potentially sensitive to alcohol, drug exposure, illicit drugs, and environmental poisons (mercury, lead, manganese, and toluene/benzene derivatives). The astute clinician must be aware of the multiple potential factors that can adversely affect cerebellar function.
