How do you decide between oral vs nasal route of entry for bronchoscopy with BAL with moderate sedation?
I trained in the early 90s. Where I trained the nasal route of entry was preferred. My experience is that patients cough less, require less sedation, and the scope is easier to guide and direct from the "stable" base of a nasal insertion. With proper nasal preparation complications related to nasal ...
What is your preferred mechanism for venting the left ventricle in patients on VA-ECMO?
Based on recent studies and evidence in the literature, my preferred approach for venting the left ventricle in patients on VA-ECMO would be guided by the individual patient's clinical scenario, with a cautious inclination towards using the intra-aortic balloon pump (IABP) over Impella. This prefere...
What further evaluation do you pursue for patients who present with vague symptoms such as subjective fevers or intermittent night sweats, who have no pulmonary symptoms but have a positive IGRA?
Great question. Another scenario that is not uncommon is some degree of cough, sometimes for long periods of time, but no other symptoms. If their risk is higher for progression to active disease (e.g., immunocompromised; recent contact with an active case) I may do more than if the risk is low. My ...
How do you prescribe a steroid taper for radiation and checkpoint inhibitor related pneumonitis?
I subscribe to the philosophy of "hitting hard, tapering slowly" for cases of pneumonitis, either radiation pneumonitis, or checkpoint inhibitor-related pneumonitis (some of those cases probably have mixed origin, with contributions from radiation and/or checkpoint inhibitors). For severely symptoma...
What factors would encourage you to choose abatacept vs tocilizumab in a patient with RA-ILD with a UIP pattern of pulmonary fibrosis?
The available literature on abatacept and tocilizumab in RA-ILD does not provide a definitive answer and hopefully with the general increase in interest in ILD we will have more definitive data in the near future. My review of the current literature suggests that abatacept has a slightly higher perc...
At what lab values (ferritin, TSAT%) would you offer IV iron therapy to patients with restless leg syndrome?
1. I am hopeful that practitioners will start understanding that ferritin alone is not enough to assess iron because of its acute phase reactivity. I like to order iron parameters after a 5-9 hour fast so the serum iron is not speciously elevated and get a ferritin and TSAT. If the ferritin is <30 a...
Do you avoid use of inhalers with milk protein in patients with a milk allergy?
According to the Advair Diskus package insert, “Immediate hypersensitivity reactions may occur after administration of ADVAIR DISKUS, as demonstrated by cases of urticaria, angioedema, rash, and bronchospasm. There have been reports of anaphylactic reactions in patients with severe milk protein alle...
Do you treat non-albicans strains of Candida on sputum culture or BAL in patients who are immunosuppressed?
I agree with these answers and do not treat either without biopsy.
What is the interpretation of an IGRA with positive TB wells and negative nil and negative mitogen wells?
We don't see positive controls in most clinical assays. They are run, of course, but hidden from view. The mitogen well is the positive control in the IGRAs. The mitogen used QuantiFERON-TB Gold is, I believe, PHA or phytohemagglutinin. PHA turns on T-cells to indiscriminately. If I remember my mito...
Do you routinely hold anticoagulation (including pharmacologic VTE prophylaxis) for bedside procedures such as paracentesis, thoracentesis, and central venous catheter placement?
We do not hold anticoagulation of any kind for paracentesis. I also do not hold anticoagulation of any kind of thoracentesis, though some places will still ask things like Plavix or DOAC to be held. We do hold ppx and anticoagulation for LP due to the risk of epidural hematoma. I do not hold for the...
