What DHE migraine protocol works best for acute treatment both in terms of dosage and timeframe?
Dihydroergotamine (DHE) is a non-specific ergot that acts on the serotonergic, dopaminergic, and adrenergic pathways. It is used as an acute migraine treatment that can be given parenterally or nasally. Oral does exist, but is not available in the USA. It may be used acutely as a rescue treatment du...
How do you approach a mildly positive finding on an autoimmune encephalitis panel when there is no other evidence of encephalitis (such as elevated CSF protein, abnormal imaging, or EEG findings)?
In general, low positive Abs by ELISA or radioimmunoprecipitation assays have low predictive value for neurological disease and cancer outside of specific clinical contexts (e.g. a PQ of 0.03 nmol/L in a patient with myasthenic syndrome).For encephalitis, GAD65 < 20 nmol/L, and PQ type calcium chann...
In patients with recurrent ischemic infarcts on the same side as an internal carotid artery lesion, is intervention warranted even if there is less than 50% obstruction?
If a carotid web is found, it would be reasonable to consider intervention to prevent thrombus formation and embolization. Grory et al., PMID 30621527
What is the utility of an oral calcium loading test to differentiate FHH from secondary hyperparathyroidism due to low calcium intake?
Both vitamin D deficiency and calcium deficiency can result in secondary hyperparathyroidism. Before entertaining the diagnosis of FHH, I would treat the patient with an adequate calcium intake of 1000 mg a day of elemental calcium preferably from dietary sources like dairy. Supplemental sources are...
Do you routinely check G6PD level prior to initiation of hydroxychloroquine?
No, we do not routinely check G6PD levels prior to initiation of hydroxychloroquine (HCQ). The American College of Rheumatology does not recommend routine testing for G6PD prior to initiation of hydroxychloroquine (HCQ), but interestingly, package inserts often recommend caution in these patients. O...
Is an EMG/NCS required to clinically diagnose Guillain barre syndrome?
GBS remains a primarily clinical diagnosis, characterized by rapidly progressive large fiber sensorimotor deficits with early arreflexia, supported by albuminocytologic dissociation in cerebrospinal fluid. EMG/NCS can be normal or non-specific in up to half of the patients in the first week and only...
How frequently do you monitor EKGs for patients newly initiated on lacosimide?
In patients who are over the age of 50, smokers, or others with a higher risk of heart disease, I get an EKG at baseline and then at a maintenance dose. During treatment, if the patient reports any new potential cardiac symptoms like palpitations, PVCs, SOB, etc, I will get another EKG.
How would you treat pemphigus foliaceous in an elderly patient intolerant to oral steroids?
It depends on the extent of the disease and the severity of symptoms. Home wet wraps, when they can be done, can be essentially as effective as oral steroids in many situations, but can be time intensive. I provide the patient with instructions and a pound jar of triamcinolone ointment. Be careful s...
What maintenance therapies do you most commonly recommend for patients with improving genital lichen sclerosis?
Betamethasone dipropionate with clotrimazole cream is my treatment of choice to provide a sufficiently potent corticosteroid while mitigating the risk of secondary Candida infections. Adjust the frequency of application from daily to once weekly to every other week for severe symptoms vs maintenance...
What is your approach to managing asymptomatic ORN of the mandible?
Do nothing until you have to.
