Quiz Please

Dr. BS has malaria, and he's experiencing significant hemolysis.
 
  • What he neglected to say was that as soon as he got home, he stopped taking his malaria prophylaxis.
    • He mistakenly thought that when he left the malaria area he was safe.
    • The anti-malarial medications typically work at one phase of the life-cycle.
    • Since the bug is going through several phases in us, it takes a number of doses, over time, to be sure they've all been killed.
    • The prophylaxis doesn't prevent us from acquiring the Plasmodia organism, it just kills them on a regular basis.
    • It's essential to take the medication prophylactically for at least 6 weeks after leaving the malaria endemic area.
 
  • The structure to the right was also seen.
    • This is a gametocyte of P. falciparium.
  • This dude is a lot sicker than he looks.
  • The degree of hemolysis could potentially cause his kidneys to quit working. (Urinalysis?)
  • Infected RBCs stick to endothelial cells,
    • Leading to capillary occlusion,
    • Causing micro-infarcts (brain, kidneys...)
    • This is the cause of 'cerebral malaria.'
So, what happened to Dr. BS?                                                                 Back
