How do you use NT-proBNP in patients with chronic kidney disease or end-stage kidney disease, given that these conditions can affect NT-proBNP levels?
NT-proBNP is most useful for (a) diagnostic uncertainty in patients who present with dyspnea, and (b) prognostication in heart failure. It is released as a result of ventricular wall stress. In CKD, the clearance of NT-proBNP is impaired, leading to elevated levels. In late-stage CKD and ESRD, volum...
What is the expected timeframe for the development of radiation myelitis and therapies that have helped with neurologic symptoms?
The incidence and the timeframe of the development of radiation myelopathy are influenced by total radiation dose, radiation dose per fraction, time between courses of radiation, and associated chemotherapy or immunotherapy. Older age, the presence of diabetes, and previous exposure to radiation are...
How do you counsel eligible patients on lung cancer screening who are hesitant because of the cancer risk from CT scans?
This is simple. The risk of lung cancer in patients who have smoked for >20 years is orders of magnitude higher than the theoretical risk of medical X-ray-induced cancers from low-dose CT (LDCT) screening. A typical LDCT scan exposes patients to approximately 1.5 mSv of radiation, equivalent to abou...

What techniques do you use in the lab to reduce the amount of contrast that needs to be used in patients with CKD?
Avoid LV angiogram. Use ECHO instead to assess LV function.
What therapies do you recommend for preventing keloid recurrence after surgical resection?
For earlobe keloids specifically, we have had reasonable results with a mixture of 40mg/ml triamcinolone mixed with 50mg/ml 5FU in a 1:1 ratio. This is injected day of keloid removal, then every 4 weeks for at least the first 6 months. No more than 0.1-0.3 mL per session. The treatments can be space...
What is your approach to young teenagers with acne who have extremely sensitive skin, cannot tolerate typical acne regimens, cannot tolerate oral antibiotics, and refuse Accutane?
The formulation of benzoyl peroxide encapsulated in silica shells is extremely well tolerated by sensitive-skinned individuals. I was involved in pre-approval studies and found it remarkably well tolerated in such patients.
How would you treat a patient with osteoarthritis of just one joint of the hand?
People do this in various ways - some people treat the joint with a large margin, others may treat the whole hand.I originally started by treating the affected joint, but pretty soon I after I switched and started treating the whole hand - pain is subjective and though it may appear localized, there...
What are some practical tips for when a patient's consistently stated goals of care do not correlate with their actions?
First, it's important to remember that most of us have inconsistent beliefs. We both want to lose weight, and we want to eat chocolate cake; we want to get an A, and we want to go to the party. So when we see inconsistencies in others' beliefs, rather than being judgmental, we should get curious. Ou...
Would you consider sotalol to be a suitable non-selective beta blocker for primary prevention of variceal bleeding in a patient who requires sotalol for treatment of arrhythmia in the setting of Fontan-associated liver disease and clinically significant portal hypertension?
The answer to this question will need to be case-by-case, unfortunately.The short answer:The priority in this patient's case for using sotalol is likely the underlying heart disease and its associated arrhythmia, and this cardiac benefit would not be achieved by carvedilol and other NSBBs. Thus, it ...
