Should mRS be incorporated into determining eligibility for extended window thrombolysis?
Key thrombolysis trials (WAKE UP, OPTION, EXTEND, TIMELESS, ECASS-4, HOPE, EXTEND IA) excluded patients with mRS of 2 or greater. The reason for this was the outcome of functional independence at 90 days. Hence, for trial purposes, to look at the outcome, it was necessary to exclude patients with di...
How would you approach the upfront management of a patient with acute unilateral vision loss with strong clinical risk factors for both cardioembolic stroke and GCA if an expedited MRI is not possible due to the presence of an AICD?
I'm definitely not an expert in this topic, but you have many clinical tools to increase/decrease your clinical suspicion for GCA vs. cardioembolic stroke. Some things I would ask: Is this patient currently in Afib? What's their CHADSVASC? Are they anticoagulated? Can we get a TTE to check for vege...
How do you treat steroid-refractory MS flares when PLEX is unavailable?
There is limited evidence on the efficacy of IVIG for MS relapses. A repeat course of IV methylprednisolone within 2-3 weeks could be considered. If the patient is not already on high-efficacy DMT, then I would also promptly initiate anti-CD20 therapy.
When do you obtain nerve biopsy to evaluate for vasculitic neuropathy in patients with distal symmetric polyneuropathies?
Excellent question. Vasculitic neuropathies can occur as part of systemic or isolated peripheral nerve vasculitis (PNSV). While the majority of PNSV presents as mononeuropathy multiplex (>50%), it is well known that the rest of the patients present either with confluent mononeuropathies (which began...
What is your approach to dosing scIG for CIDP in patients stable on IVIG?
There are at least several categories of stable patients (IgG-responders): Stable with no change in initial IVIg dose or interval (minimum effective dose unknown but clinically optimized); Stable with no change in initial IVIg dose or interval (minimum effective dose unknown but NOT clinically opti...
Do 5HT4 agonists such as Metoclopramide actually lead to improvement in symptoms for patients with diabetes related gastroparesis?
Yes, sometimes when the gastroparesis is frequent or the symptoms are tough, I do use Reglan to help. By the time they wind up in the hospital, they are really willing to have me use anything on them that might help. I explain to every patient the side effects of Reglan, including tartive dyskinesia...
What is the utility of a hypercoagulability workup in recurrent cryptogenic stroke, and what specific tests would you recommend?
Ambulatory monitoring for AFib is probably more helpful than such a thorough clotting workup.
When would you repeat antibody testing for seronegative myasthenia gravis?
I will usually recheck in 1-2 years, but I mostly focus on acetylcholine receptor antibodies. I have never seen seroconversion from MuSK negative to MuSK positive. Also, if initial antibody testing for Acetylcholine receptor binding/modulating and MuSK antibodies is negative by RIA assay, I recommen...
Do you recommend endovascular therapy in patients with isolated posterior cerebral artery stroke?
The general approach to acute ischemic stroke - (1) assess your patient for clinical suitability for EVT and then (2) look at your imaging - still applies to ischemic stroke due to PCA occlusion. For example, if the deficit is only a quadrantanopia in an elderly patient who already does not drive, t...
Are there any contraindications using nurtec in patients with headaches in the setting of recent RCVS?
I would be comfortable using Nurtec in a patient with a recent RCVS diagnosis. I am comfortable using triptans in patients with a prior stroke or MI with proper patient counseling unless they have critical/severe artery stenosis. I have had cluster headache patients who continue sumatriptan injectio...
