[Imported schistosomiasis with late complications].

Schistosomiasis is a worm disease which causes a high mortality rate all over the world. The life span of worms can be 20-30 years, so if the acute phase of the disease is not fatal very often late complications can happen. Here we demonstrate two patients who suffered from different late complications of Schistosomiasis imported to our country.

[Invasive amebiasis].

There has only a small number of invasive amoebiasis cases occurred in Hungary up to now. Introducing two of our cases we would like to call attention on these cases coming mainly from tropical countries or having been just transiently there invasive amoebiasis should also be considered. Modern diagnostic imaging technics are of importance in differential diagnosis in showing antibodies against amoebas (!) because amoebas frequently cannot be directly shown from the patients in the invasive stage.

[Imported food poisoning caused by fish toxins (ciguatoxin)].

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.
