| [hydatid cysts of the liver]. | single or multiple hydatid cysts of the liver are frequently observed in italy and the mediterranean countries. they are swellings caused by the hexacanth larva of a small cestode, echinococcus granulosus. this must be distinguished from e. multilocularis, which is responsible for alveolar cyst, and is common in central-eastern europe, but rare in italy. an account is given of the development cycle of the intermediate and final host, the protean symptomatology (dependent on the siting of the cys ... | 1984 | 6709221 |
| [chemotherapy of human echinococcosis]. | in human echinococcosis, today as in the past, surgical removal of the parasite remains the treatment of choice. beside certain conditions, adjuvant chemotherapy with vermox is indicated for echinococcus multilocularis as well as echinococcus granulosus. a substantial decrease of the echinococcal parasite mass under mebendazole is not yet known. nevertheless jaundiced patients with diffuse liver infestation with echinococcus multilocularis became jaundice-free and able to work. mebendazole toler ... | 1984 | 6714007 |
| issues in clinical parasitology: the management of hydatid cyst. | echinococcal or hydatid cyst is not commonly seen in the united states; however, two cases were seen within a 6-month period at a southern teaching hospital, and it is endemic in many areas of the world. the causative organism, echinococcus granulosus, is a tapeworm of dogs; the normal intermediate hosts are hoofed animals. when man becomes infected enlarging cysts in the liver, lung, nervous system, or peritoneum may cause considerable morbidity. while surgery traditionally has been the treatme ... | 1984 | 6720661 |
