What types of cardiac conduction abnormalities would lead you to avoid using tricyclic antidepressants?
I wouldn’t say it is a definite contraindication. But, I would want to be sure it is a longstanding patient and they are seeing a cardiologist regularly. Then, if the QTc were within reason, I would consider it; but it wouldn’t be high on my list of options.
How do you counsel non-diabetic patients who wish to start metformin to reduce the risk of developing dementia?
There have been some interesting observational studies evaluating the reduction of cognitive decline in patients with type 2 DM. First, they are all in patients WITH diabetes, so not yet generalizable to patients without DM. Second, they are observational trials, which means that they cannot adjust ...
When would you obtain optic nerve testing in patients suspected to have multiple sclerosis without a clinical history of optic neuritis?
A key change in the 2024 revision of the McDonald criteria is the addition of the optic nerve as a fifth anatomic location to demonstrate dissemination in space (DIS) in addition to periventricular, cortical/juxtacortical, infratentorial, and spinal cord, which were included in the 2017 criteria. Op...
Do you generally switch aspirin to another antiplatelet agent if a patient has a non-embolic ischemic stroke and isn't a candidate for DAPT?
I do tend to switch, mainly to impress the patient that I am trying hard to prevent another stroke, and not because there is clear evidence of one antiplatelet over another. Clopidogrel or ticagrelor would be candidates, or I might add cilostazol to aspirin, as this combination has little bleeding r...
In what clinical scenarios do you utilize opioids in patients with restless leg syndrome?
I would say in refractory RLS, i.e., the patient has failed all the options below: Iron supplementation if ferritin <50, Gabapentin/pregabalin, Dopamine agonists, and Non-pharmacological options (like the vibrating pad). *I don't love carbidopa/levodopa for RLS. It very often causes augmentation.
When do you find FDG-PET/CT helpful in the workup for autoimmune encephalitis?
Never. I only use MRI.
What is your approach to the diagnostic workup of small fiber neuropathy in patients with known rheumatic disease?
Small fiber sensory neuropathy (SFN), in general, including in patients with rheumatic diseases, should be suspected based on symptoms (positive more than negative sensory symptoms) and ideally confirmed by clinical examination showing altered temperature and/or pain/pinprick perception in the limbs...
What serum biomarkers are most helpful in cardiac arrest prognostication?
Neuron-specific enolase. This is checked at 24, 48, and 72 hours. It is, however, NOT to be used in isolation for prognostication, which is multimodal, including clinical exam after clearance of sedation (typically at 5 days post arrest), EEG (e.g., looking for reactivity of background), NSE, and MR...
When do you consider testing autoimmune antibodies for axonal polyneuropathies without clear etiology?
Dr. @Dr. First Last gave an excellent summary of the clinical red flags that should trigger antibody testing in polyneuropathies. I would like to highlight that not all antibodies are pathogenic or cause the same phenotypes/clinical syndromes; therefore, I would like to break it down by antibody gro...
How do the results of CREST-2 influence your recommendations on screening for asymptomatic carotid stenosis?
Agree with the prior comment. One important nuance is what “medical management” actually meant in CREST-2. This was centralized, protocol-driven care with structured lifestyle counseling and medication escalation, including access to PCSK9 inhibitors with costs covered. Even in that highly organized...
