What leads you to suspect that a foot drop is secondary to a myopathy rather than a neuropathic process?
Factors suggesting that a foot drop is due to a myopathy include: Clinical factors (slow progression (myopathy but also seen in CMT) versus acute or sub-acute onset (usually neurogenic), absence of sensory findings, absence of pes cavus, signs of facial or shoulder girdle weakness (FSHD can cause f...
Are there mechanisms in place to distinguish SVT with aberrant conduction from VT on external cardiac monitoring devices?
Unfortunately, there is no easy answer to this question. Differentiation of aberrancy from ventricular tachycardia can be very difficult, even with high quality 12-lead ECGs. Standard rules can be applied but many features of VT such as precordial R-wave concordance, is not possible. The best idea i...
For patients with patellofemoral pain syndrome whose symptoms continue despite an adequate course of physical therapy, what adjunctive treatments (bracing, taping, injections, orthotics, or imaging) do you consider most helpful?
After an adequate course of physical therapy (under the guidance of a knowledgeable PT), I recommend imaging to determine if there is underlying pathology like chondromalacia, chondrosis/fissuring, an OCD lesion, or perhaps a tendinopathy or fat pad impingement. Starting with a plain film (AP, later...

How do you approach folate supplementation for methotrexate-related side effects?
All MTX users should be taking some form of folate supplement. Either daily folic acid or weekly folinic acid are used and generally are effective. Tracking the RBC MCV is one way to ensure that patients are receiving adequate folate supplementation.The question has been raised whether folate supple...
Do you consider use of oral antibiotics for complicated polymicrobial intra-abdominal infections?
Depends on how you're defining "complicated" IAI. Source control is key (I like this review: Source Control and Antibiotics in Intra-Abdominal Infections), especially if there's a fistula or anastomotic leak; but once an abscess is <5cm, if I have oral options that the patient can tolerate/dosed app...
When do you consider switching a generic formulation of an antiseizure medication to the brand formulation?
This rarely, if ever, happens. The easiest way to think of the difference is not to think of brand versus generic. Think of brand as the first generic (G1), and all the rest are later generics (G1, G2, etc.). Since the active ingredient is identical amongst all formulations, the only difference is w...
When do you consider extended steroid tapers for acute asthma or COPD exacerbations?
The data doesn't support extended tapers - 5 days of 40 pred equivalent are non-inferior, and extended courses can cause harm, including increases in mortality. I only use extended tapers for patients who have, in the past have rapid symptom recrudescence with the typical shorter course. Typically, ...
How do you address/manage the recreational use of dextromethorphan (sometimes called "robo-tripping") that has risen to the level of use disorder?
This problem of "robo-tripping" has become an increasingly observed clinical issue, namely the misuse of dextromethorphan with cough medication (Robitussin). This is often in conjunction with alcohol misuse. We recently published a case report in The American Journal of Drug and Alcohol Abuse (Ledwo...
Do you routinely repeat imaging for PE after anticoagulation treatment to establish a new baseline?
We only do imaging if the patient is symptomatic still after a few weeks or has persistent chest pain or clinical signs of pulmonary hypertension. Rarely I have seen recurrent or progressive thromboembolic disease on anticoagulation. Another possible reason if the patient needs to go to surgery in t...
