How do you counsel patients with epilepsy who are interested in purchasing a seizure dog?
I recommend getting a dog because it can enhance their quality of life, similar to enjoying a glass of wine or relaxing in a Jacuzzi :-). However, I do not consider it as a medical treatment so it should be at their expense.
Does anyone have concern with giving oral antiseizure medications to patients receiving TPN because of suspected malabsorption syndrome?
Any gastrointestinal issue that alters the transition and absorption of anti-seizure medications can affect seizure medication levels in the blood. So anything from bariatric surgery to malabsorption syndrome, from TPN to prolonged constipation. Essentially, these GI issues can alter the pharmacokin...
How long do you hold pyridostigmine prior to EMG / nerve conduction study in patients with suspected myasthenia?
At least 12 hours prior to repetitive stimulation or SFEMG, per AANEM practice parameter. In our lab we recommend 24 hours if possible. Geiger and Katirji, Myasthenia Gravis and Related Disorders pp 131–152
When do you consider pembrolizumab for the treatment of progressive multifocal leukoencephalopathy?
Progressive Multifocal Leukoencephalopathy (PML) treatment remains a big challenge; the different etiologies leading to PML (HIV, malignancy, primary immunocompromise, iatrogenic, etc.) play a role in the heterogeneity of approach and outcomes. It's helpful to think of potential treatments based on ...
Is it ever appropriate to omit temozolomide in unmethylated glioblastoma?
Perhaps a different perspective on this question would be which unmethylated patients would you be willing to not treat with up-front temozolomide? The genesis of the question and conundrum comes from the modest benefit described in the above-mentioned trials for this subgroup. As Hegi herself descr...
What do you do when headache appears clinically attributed to intracranial hypotension but imaging and opening pressure are normal or not obtainable?
Regarding the IHS classification and diagnostic criteria, it is important to remember the following: The initiative came from Glaxo Pharmaceuticals in order to make it possible for the company to pursue the development of sumatriptan for migraine abortion globally. The company also paid for the fir...
How do you decide on the timing of carotid stenting after thrombectomy for an intracranial large vessel occlusion with ipsilateral carotid stenosis?
There are ongoing randomized trials that are attempting to tackle this question. So, a data-driven status will be available soon. In the meantime, clinical considerations apply: Sometimes one has to stent to gain access to the intracranial circulation, perhaps due to a very tight extracranial carot...
When is it useful to test for multiple amyloid-related biomarkers for patients undergoing work-up for cognitive impairment?
If a patient has a presentation consistent with MCI or early dementia due to AD (slow progressive decline, STM loss, no hallucinations, no neuro deficits), I will get an MRI and amyloid blood-based biomarkers. If the goal is just a diagnosis, I stop there. If they are interested in “mab” therapy, I ...
What is your approach to bothersome dyskinesias in Parkinson disease patients?
This is an interesting recent article in which a meta-analysis of various anti-Parkinson medications and surgical interventions was looked at for their effect on controlling dyskinesias as compared to placebo. The meta-analysis showed that DBS of the GPI (globus pallidus interna) was more effective ...
How effective do you find MAO-B inhibitors for the treatment of Parkinson's disease?
In the earlier stages of PD, MAO inhibitors have a perceptible effect, and in the early stages of treatment of PD, they are used alone or more effectively in combination with L-DOPA.
