Okay somebody made a topic about this last year... http://forums.dev.studentdoctor.net/showthread.php?t=911710
I'm asking you guys to see what you're going with come test day. UW lists most common secondary causes of pneumonia as S.pneumo, S.aureus, and H.flu in that order. Pathoma has S.aureus at number one. Firecracker (aka Gunnertraining) had S.aureus at number one as well. A year later...has anything changed? I just got the question, thinking the same as the person in the previous topic. I chose S.aureus and got it right, but only because S.pneumo wasn't a choice. Didn't really know about S.pneumo.

Asking for which treatment best reduces recurrence of HSV-2. I had it at acyclovir during the first episode (use antiherpetics at something other than a latent stage; answer explanation said this is good to reduce shedding and almost everything else but recurrence). Correct answer was valacyclovir (I think)... used AFTER the first episode.

Any ideas why? I took this to mean, use it while it's...latent? 😕

For the second one, simply think what med is every celeb in hollywood on? Valtrex - prevents their herpes episodes. Valacyclovir also has better bioavailability.

LOL well I will remember the concept tied to the image now for sure... but I was just thinking about the mechanism.

Like I said, they made it seem as if it was okay to use it "after the first episode" ... meaning while it's latent? I thought the point of antiherpetics was that they only work with an active virus, sooooo could someone clarify that?

But I mean... if it takes me just plain memorizing the fact, then eh. Fine. haha

Strep pneumo bro... strep pneumo for everything lobar pneumonia related (meningitis and otitis too most likely)

Common things are common, I will pretty much put strep pneumo for everything unless the question stem proves it definitely isn't by telling me the bug is gram negative, signs of a virus, atypical pneumonia, etc. (or I guess not having strep pneumo as an answer choice)

Kid with flu gets lobar pneumonia after? Strep pneumo
Homeless guy comes in with lobar pneumonia? Strep pneumo
College freshman with lobar pneumonia? Strep pneumo
Unvaccinated adolescent with lobar pneumonia? Strep pneumo
Blah blah blah diabetic with lobar pneumonia? Strep pneumo

Something like 95% of lobar pneumonia is strep pneumo.

It's like those questions that ask about infection control and they include hand washing or the questions about best preventative therapies and the guy is a smoker... Wash your hands and quit smoking!
