The clinical picture of Morvan's fibrillary chorea includes a. spontaneous muscular activity resulting from repetitive motor unit action potentials of peripheral origin (multiplets), b. autonomic dysregulation with profuse hyperhidrosis, and c. central nervous system involvement as shown by severe insomnia and hallucinosis. A case featuring all these symptoms is presented. Whereas known causative factors range from gold or mercury poisoning to autoimmune disorders, the presented case is the first one in which chronic manganese intoxication (occupational exposure) seems to be implicated. Manganese has been found to inhibit acetylcholine esterase, and, as a consequence, may produce peripheral and central cholinergic hyperactivity.

Pilot epidemiology survey has been conducted with the aim to study the effect of occupational factors on workers in the Zestafoni Manganese Processing Plant. Overall 102 workers have been surveyed. They were selected from the list circulating in the plant ambulance. Selected workers have been surveyed through a standard questionnaire. The survey revealed that prevalence of such diseases as Radiculitis, hypertension, bronchitis, gastritis, and ulcer, ocular and nasal-pharyngeal diseases are high among the workers of the Zestafoni Processing Plant. Study results have shown direct correlation between development of diseases and distance residence from the plant. Prevalence of hypertension, ocular and nasal-pharyngeal diseases, bronchitis was higher among workers lived within distance of 2-5 kilometers from the plant. Positive correlation revealed between length of job and prevalence of bronchitis, ocular diseases, Radiculitis, hypertension, cardiac diseases and gastritis. Among plant workers revealed high prevalence of symptoms characterized the central nervous system disorders such as sleep disorder, insomnia, backache, walking disorders. The results proven correlation between occupational factors and diseases and different symptoms.

Zinc is an essential trace element for humans and animals, being located, among other places, in the synaptic vesicles of cortical glutamatergic neurons and hippocampal mossy fibers in the brain. Extracellular zinc has the potential to interact with and modulate many different synaptic targets, including glutamate and GABA receptors. Because of the central role of these neurotransmitters in brain activity, we examined in this study the sleep-promoting activity of zinc by monitoring locomotor activity and electroencephalogram after its administration to mice. Zinc-containing yeast extract (40 and 80 mg/kg) dose dependently increased the total amount of nonrapid eye movement sleep and decreased the locomotor activity. However, this preparation did not change the amount of rapid eye movement sleep or show any adverse effects such as rebound of insomnia during a period of 24 h following the induction of sleep; whereas the extracts containing other divalent cations (manganese, iron, and copper) did not decrease the locomotor activity. This is the first evidence that zinc can induce sleep. Our data open the way to new types of food supplements designed to improve sleep.
