if asked about LIVER problems and parasites, which should be considered and why?
|
entomeba histolotica - remember that invasion into the intestines is quickly followed by metastasis to the liver through the portal circulation.
leishmania - it's a macrophage-infecting disorder, and in the VL (visceral leishmania) form of the disease (as opposed to CL, DCL, MCL), it routinely causes hepato/splenomegaly. splenomegaly/hepatomegaly can be malaria. also, ascaris roundworms can migrate into the liver and cause liver abscesses when scared - though you more often think about the ampule of vader/cholycistitis/pancreas visceral larva migrans has HEPATO/SPLENOmegaly as bolded concerns - the worms migrate quickly and form eosinophelic granulomas all over. echinococcus granulosis (hydatid disease) tends to make big cysts in the liver and lungs |
|
|
what parasites might be involved with CNS problems?
|
malaria - specifically P. falciparum.
toxoplasma either of the trypanosomes (the kinetoplastids, which include trypanosomas rhodesie/gambiese, which cause sleeping sickness, or chagas disease (cruzi). trichonella, after awhile, can make it up there and cause encephalitis. |
|
|
conjunctivitis and periorbital edema is likely...?
|
chagas disease! note that trichonella can also cause orbital edema.
|
|
|
if you're given a TZANCK smear that shows multinucleated giant cells, and also something about COWDRY inclusion bodies, what should you think of?
|
Cowdry bodies = Herpes.
Downey bodies = EBV. |
|
|
what parasites invade macrophages specifically?
|
think of TOXO and think of LEISCHMANIA. remember that you get tachyzoites/bradyzoites based on cellular response, macrophage infection in tissue, etc.
with leischmania, macs collect in tissue to give you CL, or spread all over your body and give you VL. |
|
|
what does orbital edema make you think of?
|
trichinella
also, CHAGAS disease! this is romana's sign in acute chagas infection. don't forget measles! |
|
|
what parasites can autoinfect?
|
pinworms
cryptosporidium strongloydies |
|
|
which can cause loeffler's syndrome?
|
those that are coughed up and swallowed:
hookworms roundworms strongylodies (though it's not explicitly mentioned, the L3 is swallowed. |
