T5 - Fasciolopsiasis Flashcards
1
Q
caused by infection with intestinal fluke Fasciolopsis buski
A
Fasciolopsiasis
2
Q
- causes Fasciolopsiasis
- live on walls of duodenum and jejunum, but can spread throughout intestines in severe cases
A
Fasciolopsis buski
3
Q
Life cycle of Fasciolopsis
A
- Unembryonated egg excreted in feces to freshwater
- embryonated egg in water
- miracidia hatch and penetrate snail
- free-swimming cercariae to water plant
- metacercariae on water plant
- water plant ingested by humans or pig, causing infection
- excyst in duodenum
- adult in small intestine (~ 3 months)
4
Q
mode of transmission of Fasciolopsis
A
- ingestion of raw or undercooked aquatic plants (e.g. water chestnuts, lotus roots) contaminated with metacercariae
- drinking contaminated water from ponds, lakes, or wetlands
- accidental ingestion of contaminated water during farming or bathing
5
Q
pathogenesis of Fasciolopsis
A
- inflammation and ulceration
- eosinophilia
- malabsorption
- severe complications: intestinal obstruction, ascites (fluid accumulation)
6
Q
symptoms of Fasciolopsiasis
A
- abdominal pain
- diarrhea
- nausea or vomiting
- malabsorption and weight loss
- anorexia
- edema
- fever
- intestinal obstruction
7
Q
Diagnosis for Fasciolopsiasis
A
- stool examination
- imaging techniques (ultrasound, endoscopy)
- patient history (dietary habits, travel to endemic areas)
8

A
- China
- India
- Bangladesh

9
Q
people at risk of Fasciolopsiasis
A
- residents of endemic areas
- farmers and agricultural workers
- individuals consuming raw aquatic plants
- children travelers
10
Q
treatment for Fasciolopsiasis
A
- praziquantel
- niclosamide
- hydration
11
Q
prevention for Fasciolopsiasis
A
- avoid raw or undercooked aquatic plants
