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...
When do you use GLP-1 receptor agonists for the management of patients with idiopathic intracranial hypertension (IIH)?
I would use GLP-1 agonists in all overweight IIH patients who did not have a contraindication if it wasn't for the cost. In the IIH treatment trial, 6% weight loss over 6 months lowered intracranial pressure by about 50 mm (acetazolamide also lowered ICP by about 50 mm, but of course, it did it much...
How do you manage anxiety for patients who are experiencing a myasthenic crisis?
For a long time, we have been taught that we should avoid benzodiazepines in this setting (also applies to patients with ALS, myositis, etc.) because of their suppressive effect on the CNS respiratory drive and the risk of exacerbating hypercarbic respiratory failure. Based on recent conversations w...
How would you approach a patient with recurrent grade 3 oligodendroglioma (MGMT-methylated, IDH mutant, 1p/19q co-deleted) 1 year after gross total resection and adjuvant chemotherapy and radiation?
There are multiple options to consider for the recurrence of grade 3 gliomas after prior chemotherapy or radiation. Regardless of whether or not the recurrence overlaps completely or partially with the prior treatment fields, options include systemic therapy (including IDH-targeted therapies for IDH...
How do you counsel patients on how to take abortive migraine medications during the prodrome period?
I do not routinely counsel patients to take abortive treatments during prodrome. It would depend on headache frequency. It would be hard if their headache frequency is high, such as >8-10 headache days per month, as they may run out of their abortive treatment. If they have low headache frequency an...
How do you decide whether to place an NGT or PEG tube in patients with dysphagia precluding adequate PO nutritional intake?
There are several factors that go into the decision of PEG tube vs continued nutrition via a nasogastric feeding tube(NGT). Anticipated time to recovery of oral pharyngial function (especially in the most common underlying illness, which is stroke). NGT can stay in place for up to 2 months without...
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 ...
Do you typically check vitamin B6 levels in patients on Sinemet?
I check B6 levels when a patient is not responding well to carbidopa/levodopa or if I have concerns about nutritional status. I have rarely found that correcting low or high B6 levels results in clinical change in patients. If a patient were to seemingly lose efficacy from ongoing levodopa therapy, ...
How do you approach escalating anti-seizure medication treatment of patients with atypical seizure semiologies?
As usual, it depends on what "atypical" means. If the seizure semiology is atypical, in that I really do not think it is a seizure, I will admit the patient to the Epilepsy Monitoring Unit (EMU) as quickly as possible for full characterization. I may or may not start a medication depending on the hi...
How do you approach selecting optimal muscle biopsy site when evaluating a patient for suspected inflammatory myopathy?
There are a few things to consider when formulating your approach to this, which include 1) the clinical exam, 2) ease of biopsy of muscle, and 3) potential confounders of diagnosis. The goal is to get a specimen from a muscle that is undergoing active inflammation. These muscles will generally be w...
