Do you choose an antibiotic with CSF penetration, such as nafcillin over cefazolin, in the setting of MSSA endocarditis with septic emboli to the brain (assuming no concomitant meningitis or brain abscess)?
The prevailing theory that cefazolin has poor CNS penetration is really based on 3-4 studies performed in the 1980s (Nolan & Ulmer, PMID 7365282) where they were extrapolating data from studies looking at cephalothin concentration in CSF. Another study looking specifically at cefazolin concentration...
How long would you wait before performing a kidney biopsy in a patient with possible AIN whose creatinine has plateaued, but not improved, after discontinuing the suspected offending agent?
If the kidney function has not resolved one week after withdrawal of the suspected offending agent, I would request a biopsy.
Do you use direct oral anticoagulants to treat port-a-cath related VTE in patients with an active malignancy?
The initial trials that established DOACs as effective and safe in most patients with cancer-associated thrombosis (Agnelli et al., PMID 32223112, Planquette et al., PMID 34627853) only included patients with lower-extremity DVT or PE but clearly showed equivalence to low-molecular weight heparin (w...
In patients with possible Bartonella henselae infection and elevated IgG titer, what is the best way to confirm the diagnosis: tissue biopsy with Warthin-Starry staining, tissue sent for Bartonella henselae PCR, or tissue sent for culture?
First of all, it is important to only test people with a compatible clinical syndrome. If the syndrome is not that of babesia, then any positive tests are likely to be false positives. This is a basic testing principle. A very low pretest probability is likely to lead to false positive testing. The ...
When do you consider the use of clonidine in gabaergic withdrawal and how do you approach the risk of masking the autonomic signs of withdrawal when it is used?
There is limited and indirect evidence for the use of clonidine in "benzodiazepine-sparing" protocols for gabaergic withdrawal treatment. Generally, an anticonvulsant is used along with clonidine in this context. This "new" data recapitulates old, mainly European, studies combining beta-blockers wit...
How do you differentiate between hyperactive delirium and excited catatonia?
This is a highly complex distinction to make for several reasons, not the least of which is that the two conditions can coexist in the same patient at the same time. This has been demonstrated in some recent studies of mainly intensive care delirious patients, though the reported very high incidence...
In light of recent trials evaluating NPO before cath (CHOW NOW, SCOFF, etc.) are centers still restricting oral intake pre-procedure?
Despite compelling growing evidence supporting that NPO is safe for diagnostic procedures (coronary angiogram, RHC), most institutions are still reluctant to change, likely related to: Medical inertia Nursing staff hesitation Upper management Medical liability M&M related concerns Lack of guideline...
How do you rule out empyema in a small pleural effusion that is not amenable to thoracentesis?
Ultrasonographic findings indicate empyema, such as complex septated or non-septated/echogenic effusions Wang et al., PMID 35984158. However, if the effusion is too small, it may be difficult to characterize, limiting the diagnosis. Moreover, when the effusion is so small, the likelihood of empyema ...
Do you routinely treat chronic sacral osteomyelitis when there is no plan for debridement or flap?
I would treat acute febrile cellulitis with a relatively brief course of antibiotics but not with a long course of IV antibiotics attempting to cure osteomyelitis, if surgical debridement is not performed.
What is your approach to management of CIED in a patient with community-acquired Staph aureus bacteremia who clears blood cultures quickly with negative follow up blood cultures within 72 hours of antimicrobial therapy and negative TEE?
The recent 2023 guidelines on AHS CIEDI defined definite CIED infection as 2 or more sets of blood cultures positive for staph aureus or CoNS + (positive TEE and/Or positive PET/CT). The guidelines stated that the organism isolated from blood cultures determines the likelihood of CIEDI, and coagulas...
