What treatment do you use for stroke prevention in cervical artery dissection?
Two prior RCTs (CADISS and TREAT-CAD) investigated this topic, each with distinct designs. The CADISS trial found no statistically significant difference in primary outcomes between antiplatelet and anticoagulation therapy for extra-cranial dissection. However, the TREAT-CAD trial failed to demon...
How do you approach evaluation of a patient referred for mononeuritis multiplex and +SSB?
Step 1: A clinical syndrome of mononeuropathy multiplex always requires an EMG study. Is the primary mechanism of the MnM axonal or demyelinating? If it is demyelinating, there are only two possible diagnoses: multifocal CIDP (Lewis Sumner syndrome, which can occur in the context of Sjogren's syndro...
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 is your first-line therapy for acute migraine treatment in the ER?
Regarding the abortive and preventive treatment of migraine, in the office or ER, we should focus on migraine-specific medications. These are the ergots, triptans, and gepants abortively, and the CGRP antibodies and gepants preventively. The patients who visit ERs every so often tend to have headach...
When should you seek hyperbaric oxygen therapy for patients with CRAO?
I usually pursue hyperbaric oxygen therapy within the 24-hour window from symptom onset for CRAO. This can be performed following TNK if given. In reality, though, there are multiple barriers to achieving this, including: Few centers offer hyperbaric oxygen therapy Labor intensive Difficulty with i...
At what lab values (ferritin, TSAT%) would you offer IV iron therapy to patients with restless leg syndrome?
1. I am hopeful that practitioners will start understanding that ferritin alone is not enough to assess iron because of its acute phase reactivity. I like to order iron parameters after a 5-9 hour fast so the serum iron is not speciously elevated and get a ferritin and TSAT. If the ferritin is <30 a...
How do you approach treatment of a glioblastoma in pregnancy?
Glioblastoma during pregnancy could be treated safely (to mother and fetus) with certain precautions and modifications. Collaboration and consultation with the patient’s obstetrician are essential. External shielding over the patient’s abdomen during treatment will decrease the external scatter radi...
How do you utilize Diamox in patients with cerebral venous sinus thrombosis and vision symptoms who do not undergo thrombectomy/recanalization?
Diamox (acetazolamide) is often used to treat papilledema with associated visual loss in cases of CVST. While there is a theoretical risk of dehydration from acetazolamide with potential worsening of the thrombosis, 1) acetazolamide is a weak diuretic and 2) the risk of blinding visual loss usually ...
How do you decide between the different oral longer acting levodopa medications?
The question would be, why are you changing, and what are you changing from? (i.e., are one of these your initial agent, a change due to Sinemet side effects, or a change because of motor fluctuations?) The current theory on dopamine replacement is "smoother is better," so the longer (and lower) you...
How do you convert between tetrabenazine, deutetrabenazine, or valbenazine for management of tardive dyskinesia?
I am not aware of a standard approach for dose conversion between VMAT inhibitors. In practice, though I have not personally done this, I would likely start the new formulation at its standard starting dose and titrate up based on tolerability. The efficacy and side effect profiles can be different ...
