Is there a minimal threshold for sleep efficiency to consider in-lab polysomnography (PSG) valid?
I am not aware of a minimum threshold for sleep efficiency. Most would go by the amount of total sleep time (> 4 hours), although a lack of any REM sleep (< 5%) would also be of concern to document validity.
Would you recommend antifungal treatment or observation without therapy in an immunocompetent patient with a pulmonary nodule who underwent malignancy workup and was found to have yeast forms consistent with histoplasma on GMS stain?
We have seen a number of patients who have had a lung biopsy for a solitary pulmonary nodule to exclude the diagnosis of cancer. When histoplasmosis is identified by pathology, we obtain a urine histoplasma antigen as well as a careful history and exam, and some lab tests for immunosuppression. If n...
How do you talk with your patients regarding radiographic expectations on surveillance CT after lung SBRT?
In general, especially when I have a discussion about the 3-month follow-up scan and tell patients that the lesion may likely be stable in size, which is often normal, and not to panic. There may also be post-radiation changes that make it more difficult to initially interpret. I think this highligh...
How do you recommend incorporating B-lines on lung POCUS as part of evaluating a patient's volume status?
Great question! As you allude to in your question, it is important to address this problem holistically in the context of the patient's history, exam, labs, and other imaging. I find that this happens all of the time, and here is how I typically break them down when applying lung ultrasound. 1) 1-2 ...
Do you recommend procalcitonin to help convince other providers to stop antibiotics in patients with pneumonia in whom a non-infectious diagnosis is strongly suspected?
I have looked at both of these studies in some depth. The de Jong et al., study, called SAPS, is perhaps the more impressive of the two, but regarding either or any study on so-called "biomarkers", even the RCT studies only make recommendations or give advice. And, more often than not, the doctors d...
Have you observed adverse mental health side effects in patients who start montelukast?
A female patient with anxiety but no history of depression or suicidal tendencies developed suicidal ideation with intrusive thoughts while taking montelukast. These were resolved within days of stopping the medication. I also treated a child brought in by his parents for extreme and sometimes viole...
How do you manage catheter-associated, upper extremity superficial venous thrombosis?
I manage catheter-associated upper extremity superficial venous thrombosis (SVT) conservatively with arm elevation, warm compresses, NSAIDs, and topical creams containing NSAIDs. Upper extremity SVT is primarily caused by indwelling intravenous catheters, so I do strongly recommend catheter removal ...
Does significant eosinophilia (8-44%) in a patient with suspected granulomatosis with polyangiitis (GPA) based on sinusitis, pulmonary nodules and positive PR3 change your management approach?
This is an important question because at times the distinction between GPA and EGPA can be difficult to make. In general, I would rely on clinical symptoms as a key distinguisher. For example, sinusitis in GPA differs from that of EGPA, with the former often causing crusting, erosions/necrosis on EN...
How do you explain the use of an AI scribe to patients the first time it is used in their care?
I use an AI scribe in my outpatient clinic, and around 90–95% of my patients agree to it. I obtain consent at the start of each visit and make it clear that it's completely optional—that they can say no at the start or change their mind at any point in the visit, with no impact on their care. I also...
For hospitalized patients with confirmed viral respiratory infections who clinically improve but remain PCR-positive, how long do you maintain isolation precautions?
This is a great question and one that routinely comes up for patients, their families, and staff. Precautions should be continued until symptoms improve and for a minimum of 14 days after the onset of signs and symptoms. This is especially important for patients who can spread virus to individuals t...
