Step I Osteomyelitis
Started by monet
hey there....actually my prof actually stated that pseudomonas osteomyelitis occurs in immuno comped pts, DM pts, and IV drug users, hence agreeing with kaplan i suppose..
I believe in IVDU staph aureus is what causes acute infective endocarditis, not osteomyelitis.
yah i just confirmed with boards and wards by ayala and it stated what i just wrote as well

S.aureus is the most common cause, while in sicklers salmonella is (due to asplenia, I presume).

Salmonella definitely MC in sicklers, and Staph MC otherwise. Staph also causes infective endocarditis in IVDU.
The answer was probably staph aureus. Diabetics and immunocompromised patients usually only get endocarditis when they are hospitalized and have lines placed in them. Anatomical valvular abnormalities is actually a more signficant risk factor for developing endocarditis then immunocompromisation is though.GiJoe said:

Out of curiosity, could candiasis be a cause of endocarditis in diabetics? I know that they are susceptible to mucormycoses, so I guess it might be reasonable that they could develop a systemic mycosis and subsequent endocarditis. I read some where that it can cause it in IVD users. Anyone have any practical knowledge regarding this (not just book learnin'!)

S. Aureus is the most common for acute endocarditis and C. Albicans tends to infect prostethic valves and is the most common cause of infective endocarditis, according to my Cardio prof in a lecture I viewed last week. It is consistent with the books I am using to study.

"but Kaplan's notes say Pseudomonas is the cause of IV drug users and diabetics"
Just FYI. Pseudomonas commonly exists in tap water and tap water is a common medium by which IV drug users use to dilute. Perhaps they should use Evian, Dasani, etc... 🙂

AS far as I know,
S Aureus is the most common cause for EVERYONE
In Sicklers salmonella is your next best bet
Pseudomonas in puncture wounds through shoes and for similar foot reasons in diabetics
Pseudomonas is also common in IV drug users because they use poor sanitary conditions to clean their needles, i.e. clean their needles in puddles where pseudomonas is rampant.
Pseudomonas and serratia endocarditis are seen in IV users.
I have never seen fungal endocarditis, but apparently occurs post open heart surgery
Common board questions: viridans group streptococcal infection is more common after dental procedures, group D enterococci are seen more often after lower bowel or genitourinary manipulation.
For sicklers (this has been confirmed) salmonella is more common than staph for osteomyelitis...for everyone else it is Staph.
I've read both, but...
in real life Staph aureus is most common cause of osteomyelitis for everyone, but Salmonella is also common for sicklers.
in a Step I question, probably any sickler with osteo will have Salmonella. Gotta love those buzzwords.
