How clinically meaningful are the differences in the primary outcome between treatment and placebo groups in the CENTAUR trial?
Defining the term "clinically meaningful" proves challenging. Patients involved in the three positive and approved drug trials are unable to detect a slowdown in the progression rate. Attempts were made to gauge ALS providers' opinions regarding a meaningful change in the ALSFRS-R scale, suggesting ...
Would you offer adjuvant radiotherapy for a gross totally resected WHO grade 2 hemangiopericytoma/MFT of the brain in a patient with active multiple sclerosis?
This is a tough question to answer, as there are risks associated with either recommending post-operative radiotherapy or not. Hemangiopericytomas are rare intracranial tumors that arise from pericytes, support cells found in the wall of meningeal capillaries. They are part of a larger spectrum of m...
For patients with newly diagnosed brain metastases without a history of seizure activity, do you routinely start anti-seizure medication?
This is a common clinical question that has been repeatedly explored in meta-analyses and clinical guidelines. Consistently, there's no evidence to support primary prophylaxis for seizures in patients with brain tumors including brain metastases. In summary, the data does not support the routine use...
Would you recommend anticoagulation in a pediatric patient with metastases in a dural venous sinus?
For an adult patient would consider if there is evidence of tumor-associated thrombus on initial imaging or follow-up, but not usually from a prophylactic perspective. This may be different in a pediatric patient and also might depend on the primary malignancy or hematologic, or neurologic comorbidi...
What are your preferred anti-seizure medications for Doose syndrome?
Meds are not listed in any necessary order: valproic acid, clobazam (any other benzo), ketogenic diet, and felbamate. The ketogenic diet and felbamate are the most effective.
What is your hemoglobin target for PRBC transfusion in cases of acute brain injury?
At our institution, our hemoglobin goal has always been 7 except for TBI patients, in which the goal has been 8.5. The TBI goal was a bit arbitrary and really just split the difference between 7 and 10 given some of the contradictory data. Given the new HEMOTION and TRAIN trials, we are revisiting o...
What workup do you recommend for otherwise healthy migraine patients that develop dizziness with episodes?
The workup should exclude other potential causes of vertigo including CNS disorders, and Meniere's disease, with neurology examination, MRI brain, videonystagmography, or electronystagmography. An article also evaluated vestibular migraine versus migraine without vertigo and found in several studies...
How would you approach the workup of unilateral chorea with a normal MRI?
I would first rule out Sydenham chorea by checking ASO titers, DNase B titers, ESR, and CRP, and performing an echocardiogram and EKG. I would also recommend an MR angiogram if not already done for Moya-Moya. Following that, I would check copper levels, ceruloplasmin, serum amino acids, serum lactat...
Is there a role for using parenteral anticoagulation for occlusive extensive ICA thrombus with acute onset of symptoms when patients are not candidates for endovascular therapy, such as low NIHSS?
If interpreting the question correctly, it refers to an extensive/occlusive thrombus in the ICA as an acute vessel occlusion? In such cases, my decision between the medical and endovascular approaches largely depends on the segmental location of the occlusion. For a proximal cervical-segment ICA occ...
How frequently do you re-evaluate AChR and MuSK antibodies in patients with clinical and electrodiagnostic evidence of seronegative myasthenia gravis?
I usually recheck AchR binding antibodies 1-2 years after the initial negative test because some patients will “seroconvert”. I don’t recheck MuSk if the initial was negative. And one recent “secret”: the University of Oxford in the UK for years had patented the development of a cell-based assay to ...
