Let us use this case to highlight clinical pearls about liver abscess:
Two major categories
1. Pyogenic liver abscess
2. Amoebic liver abscess
In this case, there are factors that favor pyogenic liver abscess: endocarditis, septic pulmonary emboli and endophthalmitis

#IDDailyPearl quick Tweetorial on ART in the setting of severe renal impairment (GFR <30, not in dialysis). @erodedbyewaves and @ewelford
When CrCl <30, technically should stop TAF and FTC/3TC. TAF can be used down to CrCl 15 not on dialysis (think HBV monoinfection tx data) BUT technically FTC or 3TC should be renally-dosed at these lower CrCl.
I've seen FTC and/or 3TC continued at these lower CrCl levels since risk of lactic acidosis and/or other AE is still low but technically would not be "appropriate"

I know giving q4h penicillin G for a viridans group streptococcus endocarditis feels very classic and elegant, but man is it ever awful for the patient in hospital. They can’t go anywhere because they’re getting antibiotics so often! #IDDailyPearl
So here’s my food for thought question: assuming we don’t do oral treatment, and given that endocarditis is actually pretty rare, why don’t we give ceftriaxone rather than Pen G given the inherent issues with the latter? I’m only meaning to spark discussion. No agenda :)
It’s good stewardship bcz there little ecologic effect treating a rare entity. Less problems with PICC blockage. Easy to give daily dosing. Better quality of life for patient for time you’re giving it. No need for dosing acrobatics. No renal adjustment. Easy to remember dose.

2/ Arnold Rich stated: “There is no more puzzling circumstance in the pathogenesis of pulmonary tuberculosis […] than the peculiar fact that in the adult the disease begins almost invariably in the upper portion of the upper lobe“

3/ M. tuberculosis is an obligate aerobe (they have an absolute requirement of O2 to grow).
*Tubercle bacilli respire maximally in vitro at O2 concentrations of 20-40%
*Experimental infections in animals are inhibited by very low O2 concentrations
