Cestodes Flashcards
Main cause of acquired epilepsy in developing countries
T. Solium Cysicercosis
Life Cycle of Taenia Solium
Human: Definitive host–Ingestion of the T. Solium EGGS by fecal contamination causes human cysticercosis
If we ingest theh infected Pork WORM: Taeniasis
What is the natural progression of intraparenchymal NCC
Cyst–>Granuloma–>calcifications (or disappearance)
Management of SINGLE lesion neurocysticercosis, intraparenchymal
albendazole + steroids short term
AEDs at least 6 months
Intraventricular NCC treatment
Neuroendoscopy/removal Albendazole/praziquantel, Shunt
How do you diagnose NCC?
NEUROIMAGING. NOT serology!!
You need to know what size, where are they, etc.
What is Brun’s syndrome
With change of position, you get acute blockage of CSF flow (likely from cysticerci in the 3rd ventricle)
If you see a lacunar infarct in patient with NCC, what type of NCC is this
Lacunar infarcts are common with basilar inflammation (i.e. subarachnoid NCC or other chronic meningitis)
How do you treat cysticerci in lateral and third ventricles
neuro-endoscopy + medical management (alb, prazi, steroids, AEDs)
Other than neuroimaging, what else can you do for NCC
ELISA or Serology but really the best is neuroimaging if you are concerned for NCC
NCC with ICP elevation, what is a treatment
CONTRAINDICATION to antiparasitic drugs because of cerebral edema. Fix ICP first
Basal NCC-ABZ + Steroids, VP shunting
subarachnoid NCC-prioritize management of hydrocephalus. ABX + PZG + Steroids +AEDs
How to treat cysticercal encephalitis
dont use antiparasitic drugs-treat cerebral edema first
Where do you find dwarf tapeworm? What is the definivite host?
Hymenolepsis Nana: Warm countries (South america, egypt, sudan, thailand, india)
Definitive host=man
