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...
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...
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 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 ...
What is a reasonable class of antihypertensive to start in patients with HCM who remain hypertensive and symptomatic in spite of maximal doses of beta blockade or calcium channel blockers?
My answer is based on the experience and not the research data per se in HCM: I will add low-dose HCTZ (12.5 mg daily). It won't cause dehydration or hypokalemia and might do wonders in managing HTN in these patients. One of the cheapest and most effective! Or I would consider Spironolactone instea...
How do you approach interpreting a low titer dsDNA (such as crithidia 1:40 to 1:80) in the setting of a moderately elevated ANA without other specific features of SLE?
Serologies are not a diagnosis nor are they diagnostic. This patient does not NOW have lupus. Are there first-degree relatives with SLE? Does this patient have any other autoimmune disorders like Hashimoto thyroiditis? What to do? Follow-up and education. Routine follow-up and welcome phone calls to...
Is methacholine challenge on its way out?
I have not needed to order the challenge test for a long time now. I see the need for this test is declining.
What is your approach to anticoagulation in a patient with AKI and cirrhosis who has frequent filter clotting on CRRT?
A meta-analysis (Qi et al., PMID 37186766) compared 348 patients from 9 studies receiving RCA to 127 patients from 5 studies receiving heparin anticoagulation. Among the RCA recipients, the incidence of citrate accumulation, metabolic acidosis, and metabolic alkalosis was 5.3%, 26.4%, and 1.8%, resp...
What is your approach to secondary prophylaxis for C difficile infection during concomitant antibiotic use in a patient with a history of C difficile infection?
We have been restricting secondary prophylaxis to those patients with severe protein malnutrition, receiving immunosuppressive chemotherapy, generally at the extremes of age who require unavoidable systemic antibiotics that cannot be withdrawn. Based on the 2024 paper by Ronza Najjar-Debbiny et al.,...
How would you treat ESRD patients on hemodialysis with recurrent AV fistula thrombosis found with low protein C activity?
I assume that the patient described in the vignette has a negative family and personal history of VTE. PC (and PS) deficiencies are relatively common in ESRD patients. The low levels are thoughts to reflect a combination of true (acquired) reduction and the assay interference rather than true defici...
