When would you initiate exchange transfusion in babesiosis and significant hemolysis?
There are no studies that answer this question. Some people have extrapolated from the use of exchange transfusions for severe malaria to consider using this treatment with babesiosis, another intraerythrocytic protozoan infection. Unfortunately, though there are some studies on malaria, the results...
What criteria are used to choose a specific dose of aspirin in ischemic stroke?
In my training and current practice, most stroke specialists have adjusted from the standard 81 mg aspirin dose (one-size-fits-all) to weight-based dosing. A meta-analysis of RCTs (Rothwell et al., PMID 30017552) suggests that low-dose aspirin may not suffice for stroke prophylaxis for patients who ...
What is your preferred initial imaging choice for a patient suspected of having renal artery stenosis who does not have any contraindications to imaging contrast media?
If the suspicion is for atherosclerotic-related renal artery stenosis (>55 years old, history of systemic atherosclerosis, tobacco use), then I start with a renal duplex ultrasound. Importantly, I do not get a renal duplex ultrasound on all patients with resistant hypertension. If the suspicion is f...
How do you adjust your management strategy to address the unique needs of anuric end-stage kidney disease patients when treating diabetic ketoacidosis?
There is no osmotic diuresis, and they do not need IVFluid, the opposite is true they may appear intravascularly overloaded, and will respond to insulin alone, they do not need HD for this. They will not be K deficient, do not give K. Their potassium will likely respond to insulin alone, and should...
What parasites do you screen for in your workup of HES?
In my practice, if GI symptoms (particularly diarrhea), then culture for stool ova and parasites (broad screen). If there are no GI symptoms, then only screening for Strongyloides with a blood test for Strongyloides antibody. If there is a recent travel history or a patient immigrated from areas wi...
Would you consider an ICD for secondary prevention in an otherwise previously healthy adult found to have severe LV systolic dysfunction admitted s/p VF/VT arrest due to profound hypokalemia and hypomagnesemia, or defer implantation given resolution of arrhythmias after correcting electrolyte abnormalities?
I would need to have much more information. For example, does this person have CAD and/or a definable etiology for the cardiomyopathy? Does he/she/they have a family history or genetic profile that might influence the decision. Importantly, I would not dismiss a secondary ICD in this person based on...
What is the upper limit of blood glucose target in hyperglycemic critically ill patients?
I don't think there's much data that argues that setting the upper limit between 180 and 200 will make much of a mortality difference. The SCCM guidelines center around initiation of insulin infusions, and doesn't seem to say that we should start insulin infusions for BG>180, but tolerate it up to 2...
How do you approach management of recurrent idiopathic pleuropericarditis?
The first line is colchicine and NSAIDs until the pain resolves, CRP normalizes, etc… After this, if the CRP tracks with the symptoms, fluid reaccumulation, and/or cMRI evidence of the pericarditis, I find il-1 inhibitors work very well.
Would the diagnostic yield for ABIs or peripheral arterial duplex doppler in a patient with metal rods in both legs be similar or acceptable in comparison to those tests in a patient without metal rods?
Ankle-brachial index(ABI) relies on the compression of upper and lower extremity arteries with blood pressure cuffs and measuring the ratio of blood pressure between them. While I am not aware of specific studies in those with metallic rod fixation, ABI measurements should have similar utility as lo...
How do you use IVC collapsibility on POCUS to inform decisions for managing hypotension?
If a hypotensive patient is lying flat and spontaneously ventilating with a >50% collapse of the IVC (IVCmax - IVCmin/IVCmax x 100%) during a 'sniff' test then I would consider them 'volume tolerant'. They may not be responsive to IVF but it is unlikely that additional IVF will be harmful. Absolute ...
