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...
What is your approach to secondary stroke prevention in patients with atrial fibrillation and intracranial stenosis (>70%)?
The patient clearly needs to be on an anticoagulant for stroke prevention with atrial fibrillation and I would choose apixaban. If an antiplatelet is added to the apixaban, the risk of a major bleeding side effect is significantly increased. It is uncertain if apixaban is effective in reducing the r...
What lab monitoring and frequency do you recommend in an otherwise healthy young patient on biologics for psoriasis?
Yearly QuantGold testing in low risk patients has been shown to be unnecessary and actually carries a significantly higher risk of false positive than true positive. Unfortunately, many insurers still require yearly testing. I don't know of any data to support any other yearly lab testing for the dr...
How do you recommend mitigating the risks of using beta blocker and clonidine therapy in combination for management of hypertension?
Beta blockers vary in lipophilicity, which affects blood-brain barrier permeability. Propranolol and metoprolol readily cross the blood-brain barrier, while other beta-blockers like nebivolol do not. The CNS side effects of fatigue, depression, and insomnia are more likely to worsen if using a lipop...

Do you ever use ocular ultrasound in evaluation of papilledema?
As a neuro-ophthalmologist, I never use ultrasound to make a diagnosis of papilledema. I do use it to reveal optic nerve head drusen that also cause axoplasmic flow stasis and can mimic papilledema. A high quality set of fundus photos is very useful for determining the presence of optic disc edema.
With OpenBiome no longer in operation, what is your current approach for obtaining FMT for inpatients with acute severe/fulminant C. difficile infection unresponsive to antibiotics?
Consider Rebyota by enema or flex sig, similar to what you had done with standard FMT.
How do you use NT-proBNP in patients with chronic kidney disease or end-stage kidney disease, given that these conditions can affect NT-proBNP levels?
NT-proBNP is most useful for (a) diagnostic uncertainty in patients who present with dyspnea, and (b) prognostication in heart failure. It is released as a result of ventricular wall stress. In CKD, the clearance of NT-proBNP is impaired, leading to elevated levels. In late-stage CKD and ESRD, volum...
How soon following pacemaker implantation can patients safely undergo elective cardioversion?
That is a good question. From a technical standpoint, a cardioversion can be done at any time after a pacemaker implantation. In the past, we often did defibrillation threshold testing on patients on the EP lab table after implanting an ICD and sometimes they would require a shock externally. This w...
Do you generally prefer to continue hydroxychloroquine in lupus patients who develop ESRD despite the low likelihood of clinically active disease in this patient population?
Yes, I do. In my experience, nephrologists tend to forget or neglect the use of HCQ. HCQ can prevent lupus flare-ups and progression of disease not to mention CV benefits as well as being helpful in addressing APS if present.
