What agents do you utilize for mucociliary clearance during the index hospitalization of patients post lung transplant?
Early post-operatively bronchoscopy is the mainstay for the removal of secretions which may be quite thick and obstructive related to the sloughing of pseudomembranes (ischemic epithelium). We will transition from bronchoscopy to hypertonic saline (3% or 5%) nebulized BID with bronchodilators prior ...
Have you seen rheumatoid nodules or RA-ILD in patients with seronegative RA?
By definition, rheumatoid nodules are considered to be a highly specific manifestation of RA. Regarding the first part of the question, one should never see true rheumatoid nodules in someone who does not have seronegative RA. Though there are sporadic case reports of finding these nodules in people...
How do you clinically distinguish between group I and group III PH in patients with CTD-ILD?
The distinction between pulmonary hypertension (PH) of the group 1 (pulmonary arterial hypertension (PAH)) and group 3 (pulmonary hypertension (PH) due to lung disease and/or hypoxia) is essential since the management is different. In group 1 PH we stratify the risk and treat with a variety of PAH-s...
Do you give additional pneumococcal vaccines after a dose of PCV20 in patients with asplenia?
Assuming the patient otherwise does not have immunocompromising conditions other than asplenia, following age-appropriate vaccine schedules is appropriate. A dose of PCV20 appears to provide adequate protection. However, ongoing surveillance studies will be important to answer this question, and vac...
What is your approach to a patient who has a cardiac PET scan suggestive of sarcoid but no other supporting evidence of a diagnosis of sarcoid?
The diagnosis of cardiac sarcoidosis (CS) can be challenging, as non-necrotizing granulomatous inflammation is frequently patchy, and as a result, may not be present on endomyocardial biopsy even in the setting of active cardiac disease. Many institutions, including ours, attempt to avoid endomyocar...
When is it considered inappropriate to omit pathological mediastinal lymph node staging for non-small cell lung cancer?
This is a very good question often debated by thoracic radiation oncologists with their thoracic surgery colleagues and can get complicated. The best way to look at it, in my opinion, is to understand the sensitivity and specificity of FDG PET/CT to detect true mediastinal nodal disease. For example...
Is there still a role for direct laryngoscopy in the intubation of patients in the ICU?
I believe you have to be proficient in many techniques in case you need alternatives when performing a procedure. This applies to DL. Video intubation has facilitated intubation greatly but the technique is different and if it fails the default is DL.
How do you manage diarrhea in a patient with CTD-ILD on MMF who was recently started on full dose nintedanib?
It is important to keep in mind that immunomodulator therapy is also frequently associated with gi toxicity (MMF, methotrexate, leflunomide, azathioprine, etc.). Given this, it is important to begin one therapy at a time in order to mitigate side effects and do understand which agent is responsible....
Do you continue to prone patients with severe ARDS after initiation of VV-ECMO?
Not routinely - although we have occasionally proned VV ECMO patients at our center. Reasons for not proning include: Cannula dislodgement/displacement risk (although Roca et al, PMID 34461971 reviews the literature on proning with VV ECMO and the risk of major line complications is small). Generall...
What else do you consider in the differential diagnosis for pulmonary-renal syndromes if there is low clinical and serologic evidence of AAV, Goodpasture's or other rheumatologic disease (SLE, RA, APS, Scleroderma)?
Endocarditis can mimic vasculitis and can have pulmonary hemorrhage. You CANNOT miss that one. Sarcoidosis is I suppose a pulmonary renal syndrome. Renal vein thrombosis from MGN with a pulmonary embolus is I suppose a pulmonary-renal syndrome.
