| ascariasis | <radiology> Most common parasitic infection in the world, endemic along Gulf Coast, Ozark Mountains, Nigeria, Southeast Asia, organism: Ascaris lumbricoides, age: children (1-10 y.o.), cycle: soil to duodenum to venules/lymphatics to lung to brochus to mouth to jejunum, location: jejunum greater than ileum (99%), duodenum, stomach, common bile duct, pancreatic duct, symptoms: colic, eosinophilia, appendicitis, haematemesis, pneumonitis, jaundice X-ray: 15-35 cm long filling defects, whirled appearance (bolus of worms) complications: intestinal obstruction/perforation, intermittant biliary obstruction, liver abscess (rare), granulomatous stricture of extrahepatic bile ducts (rare) (12 Dec 1998) |
| ascariasis infection | <microbiology> Infection by the nematode Ascaris lumbricoides and is characterised by an early pulmonary phase related to larval migration and a later, prolonged intestinal phase. Adult worms are 15-40 cm in length and maintain themselves in the lumen of the small intestine. Infection occurs after ingesting eggs contained in contaminated food or more commonly, by transmission to the mouth by the hands after contact with contaminated soil. Treatment is with mebendazole or pyrantel pamoate. (27 Sep 1997) |
