Do you recommend treating Candida albicans on urine culture from an indwelling catheter in a patient with septic shock?
In a patient with septic shock, one is typically obligated to treat all things until further culture data is back, etc. If there are other clear causes of shock, I would not treat the candida (though I would try to change the catheter ASAP). If the patient is extremely ill and no other sources of in...
How would you approach a stable 3 cm iatrogenic pneumothorax in an asymptomatic patient?
Most iatrogenic pneumothorax after bronchoscopy resolve without intervention. If asymptomatic and without radiographic evidence of developing tension physiology close monitoring while on 100% O2 is appropriate without intervention unless the patient becomes symptomatic or develops signs of tension p...
What is your preferred laboratory test to assess treatment response or infection resolution in patients with bacterial pneumonia?
I don't generally check a laboratory test to assess resolution. I go more by their improved clinical status and seeing them get back to baseline oxygen status. If I am trending a WBC or procal, I do like to see it trend down, but it's not the only lab I hang my hat on to decide if someone has resolv...
What serologic biomarkers do you send to assess for sarcoidosis at baseline and/or during flares, in patients where it may correlate with disease activity?
Elevated ACE, dihydroxy vitamin D, and soluble IL2r levels have been shown to correlate with disease activity, but it is important to keep in mind that the sensitivity and specificity are variable and they should never be used in isolation to diagnosis or assess disease activity in sarcoidosis. The ...
How do you approach a patient with sarcoidosis who cannot tolerate steroids and who is developing ILD?
As with most questions about sarcoidosis, clear understanding of the relevant clinical context should first be established. While interstitial lung disease (ILD) is a common manifestation of sarcoidosis, it often can be safely monitored without treatment, and so radiologically identified sarcoid ILD...
How would you manage cardiac sarcoid with intolerance/contraindications to methotrexate, azathioprine, and mycophenolate/mycophenolic acid and that has proven refractory to adalimumab and infliximab as determined by PET?
I think it would be important to know the doses of the medications 'failed'. Similarly to allopurinol dosing and gout prophylaxis 'failures', I find most patients I see for consultation with this story are not on high enough doses, need combo therapy, or are not on the medication long enough. Meth...
What is the rationale/evidence to support doing 4 puffs of albuterol vs. 2 puffs for a reversibility study?
The rationale per ATS in 2005 is that 4 puffs of albuterol is higher on the dose-response curve and thus would potentially avoid getting a suboptimal (< 12%, < 200 mL) response from 2 puffs. Having said that, there was a study of this issue in 240 pediatric patients showing non-inferiority of 2 puff...
How do you approach management of chronic cough in patients with ILD?
By the time an individual presents with ILD and cough, and fibrotic therapy has started, there’s almost no use for increasing the dose to treat cough instead of a neural modulator such as gabapentin, and if cough is interrupting sleep, low-dose narcotics. The spinoff is that narcotics may reduce dia...
What is your approach to counseling severely frail older adults regarding their planning for invasive life-sustaining therapy?
My approach is pragmatic, evidence-based, and bi-directional. Patients/family make the decision, but I ensure they are fully informed about the pros and cons and provide them time to think through.
Under what circumstance would you order dalbavancin instead of vancomycin or daptomycin for MRSA endocarditis?
The short answer is active/recent IV drug use. Personally, I don’t or didn’t agree with not using PICC and 6 weeks of daily IV abx. My understanding, although it may be outdated, is that there is evidence that most patients would not abuse the PICC. That had been my experience, I had only one patien...
