How would you interpret a temporal artery biopsy demonstrating focal chronic inflammation in the adventitia associated with small adventitial vessels and nerves without inflammation of the intima and media and without giant cells?
Peri-adventitial inflammation seen in temporal artery biopsies is generally a non-specific finding. This was demonstrated nicely in a recent histopathological study from Mayo Clinic evaluating temporal artery samples from autopsy cases. Over 40% of temporal arteries from older individuals (with no h...
At what point is a skin biopsy indicated in patients with neuropathy?
Skin biopsy is indicated when small fiber neuropathy is suspected- that is, a patient with usually painful paresthesias- positive sensory symptoms, and less often negative sensory symptoms alone, and normal EMG/NCS. Clinical exam usually, but not always, will show some signs of small fiber involveme...
Is there a role for intravenous temozolomide in place of oral for the 5-day dosing q 28 days after surgery/XRT+Temozolomide for glioblastoma multiforme?
I have never used IV temozolomide, or seen it used by others in practice for GBM, and do not think it would offer a significant benefit over oral formulations as it has high oral bioavailability. I have seen and prescribed liquid oral temozolomide for patients with dysphagia.
How do you work up incidentally found papilledema in the emergency room?
The term "papilledema" should be reserved for optic disc swelling due to increased intracranial pressure - but I assume that this question is asking what to do if the fundus examination looks abnormal (blurred disc margins perhaps) when there are no visual symptoms or symptoms of increased intracran...
When do you consider nerve blocks for headache management in patients admitted to the neuro-intensive care unit with subarachnoid hemorrhage?
For aneurysmal SAH, I try different medication combinations for the first 5-7 days. After this time frame, if headache pain is still severe and/or the patient uses opioid meds too frequently, I request an occipital nerve block from our pain management team. In my experience, about two-thirds of pati...
Do you repeat a lumbar puncture in a patient living with HIV diagnosed with and treated for neurosyphilis and if so, when?
This is a complex issue, and there isn't a one-size-fits-all approach. There are no hard and fast guidelines in place. If the initial CSF abnormalities include only reactive CSF VDRL, along with modest protein elevation and mononuclear pleocytosis (both of which are consistent with HIV infection), a...
What role do anti-seizure medication levels, such as levetiracetam, serve in seizure-free patients?
In patients with epilepsy who are being treated with antiseizure medication, the change in doses has to be driven by clinical data, mainly by seizure recurrence and/or adverse events. If a patient has been seizure-free and is not having adverse events, there is no need to check for blood levels, as ...
How do you approach the management of patients on lamotrigine who develop a minor rash?
Lamictal rash can be dangerous but if we stop or switch lamictal for any rash during treatment we can run out of options soon. Get a good history and pictures, if possible. How long have they been on lamictal and was there a recent dose change or did the pharmacy change their generic brand? Have an...
How do you manage myasthenia gravis in patients over the age of 90?
Steroids always carry the risk for side-effects and these need to be explained to each patient and weighed against co-morbidities to determine if they are in fact reasonably indicated in a particular instance. Nevertheless, steroids should be first-line agents for elderly MG patients as a significan...
How do you approach the treatment of biopsy proven ABRA (amyloid beta related angiitis)?
I start with a prednisone taper, 60 mg daily to start, taper over a few weeks. If symptoms or scan findings worsen, I would add an immunosuppressive agent such as azathioprine. Howard Kirshner MD
