Current literature on neuropathies caused by metabolic defects and exogenous toxins is reviewed. Recent work on the molecular basis of hereditary amyloidosis is initially considered followed by various aspects of diabetic neuropathy and then the effects of ciguatoxin and podophyllin on peripheral nerves.
We propose a significant relationship between bursts of ciguatera following disturbance on a reef area and seepages of endo-upwelled interstitial waters, rich in nutrients. Such waters cannot continue to be used by a stressed or eliminated algal-coral ecosystem and are taken up by epibenthic planktons i.e. Gambierdiscus toxicus, of which population increases sharply.
Various types of fish-poisoning mainly occur in tropical areas. Saxitoxin, tetrodotoxin, scombrotoxin and clupeotoxin are heat labile while ciguatoxin, in contrast, is heat stable thus it may be the source of severe poisoning even in case of thorough cooking and baking. In December 1987 a mass alimentary poisoning occurred following ingestion of fish meat in a group returning from Cuba. The most severe case was admitted to our department with symptoms of extended paresis. Diagnosis of ciguatoxin poisoning was established based upon the history, clinical features and laboratory results. Nowadays exotic, remote "Fish-poisoning" cases have to be taken into consideration even in our country.
