Bilharzia: A schistosome, a trematode worm parasite. Three main species of these worms’Schistosoma haematobium, S. japonicum, and S. mansoni’cause disease in humans. Larval forms of the parasite live in freshwater snails. When the parasite is liberated from the snail, it burrows into the skin, transforms to the schistosomulum stage, and migrates to the urinary tract (S. haematobium), or liver or intestine (S. japonicum or S. mansoni), where the adult worms develop. Eggs are shed into the urinary tract or the intestine, where they hatch to form another form of the parasite, called miracidia, that can then infect snails again, completing the parasite’s life cycle. Also known as schistosomiasis.
Bilharziasis: a parasite infection by a trematode worm acquired from infested water. Also known as schistosomiasis. Species which live in man can produce liver, bladder, and gastrointestinal problems. Species of the schistosomiasis parasite which cannot live in man cause swimmer’s itch.
Biliary: Having to do with the gallbladder, bile ducts, or bile. The biliary system itself consists of the gallbladder and bile ducts and, of course, the bile. For example, biliary atresia is the absence or closure of the major bile ducts, the ducts that drain bile from the liver.
- Biliary atresia
Biliary atresia: Congenital absence or closure of the major bile ducts, the ducts that drain bile from the liver. Biliary atresia results in a progressive inflammatory process which may lead to cirrhosis of the liver. The infant looks normal at birth but develops jaundice after the age of 2 to 3 weeks with yellowing of […]
- Biliary compression
Biliary compression: Abnormal pressure on the biliary tree compromising the normal drainage of bile.
- Biliary decompression
Biliary decompression: A procedure done to remove pressure on the biliary tree and permit the normal drainage of bile.
