How have you incorporated prescription digital therapeutic treatments for chronic insomnia, such as SleepioRx or Somryst, into your practice?
I have not yet prescribed any of the digital therapeutic treatments, but there are key differences. The US Department of Veteran Affairs developed CBT-i Coach based on the therapy manual CBT for Insomnia in Veterans, and the app is free to use. CBT-i Coach is intended to augment face-to-face care wi...
What criteria do you use to determine if a change is clinically significant while evaluating PFTs?
This can be determined using various criteria, including whether or not a measurement has dropped below certain severity thresholds and/or if the observed change is greater than one might expect through general variability. Various professional societies have recommended using the lower limit of nor...
Under what circumstances do you recommend POCUS guidance for lumbar puncture?
If the circumstances allow for it, I would use ultrasound for guidance for LP every time a LP is performed. This allows for continued practice in identification of the landmarks and improves accuracy in POCUS when it's truly needed, as in obese patients, where landmarks are difficult to palpate. Got...
Do you perform EBUS-TBNA for staging in patients with biopsy proven malignant lung nodules with no lymphadenopathy on CT chest and PET scan?
I agree that incidence is low, but estimates for radiographically occult nodal disease range from 10-20% and the fact is there isn't great literature on this. A PET scan is a decent test, better than a regular CT, but there are still a significant minority of patients that are mis-staged when an EBU...
Will you incorporate the use of tirzepatide in the management of patients with OSA?
Yes! However, the best methods to incorporate GLP-1s into the practice of Sleep Medicine have yet to be determined. Hopefully, our professional organizations can provide us with clinical practice guidelines to better direct our practice in this area.For those that have not had a chance to review, SU...
Do you routinely repeat imaging for PE after anticoagulation treatment to establish a new baseline?
We only do imaging if the patient is symptomatic still after a few weeks or has persistent chest pain or clinical signs of pulmonary hypertension. Rarely I have seen recurrent or progressive thromboembolic disease on anticoagulation. Another possible reason if the patient needs to go to surgery in t...
How do you approach dyspnea in a patient with seropositive rheumatoid arthritis with normal imaging findings but abnormal PFT findings (restriction, reduced DLCO)?
Pulmonary pathophysiological abnormalities are common in individuals with rheumatoid arthritis (RA) and respiratory symptoms. In individuals without respiratory symptoms, abnormalities may even be detected by lung function testing or high-resolution CT imaging. Any compartment of the lungs may be in...
How do you determine the time window for which to monitor for cerebral edema development in patients with brain injury?
The type of edema definitely matters. The two big categories of cerebral edema include cytotoxic and vasogenic edema. Cytotoxic results from free water accumulation in dying cells from acute brain injury, while vasogenic edema results in disruption of the blood-brain barrier. The classic teaching is...
What are the best techniques to reduce POCUS artifact and increase the diagnostic accuracy of lung ultrasound?
It is important to first clarify that essentially all of lung ultrasound is artifact, and this is a great illustration of how artifact can actually help us to make a diagnosis rather than obscuring it. When we see B-lines, for example, that is an artifact that does not represent a similarly appearin...
Do you plan to use benralizumab to treat acute exacerbations of asthma or COPD associated with eosinophilia?
Currently, I do not use benralizumab for acute exacerbations of asthma or COPD, even with eosinophilia. Its role is in long-term maintenance for severe eosinophilic asthma, not in the acute setting where rapid-acting therapies are required. I’ll reconsider if emerging data support the benefit in exa...
