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...
How long after initiating mycophenolate do you wait before tapering prednisone off in patients with myositis-associated ILD?
Taper Pred after 6 weeks MMF tapering to prednisone 20 mg/day and hold this dose for 6-8 weeks monitoring for relapses. If no relapse, taper to Prednisone 10 mg/day.
If PFTs are done on different machines or different places, are the comparisons valid?
Pulmonary function test results might differ slightly when performed at different facilities due to staff engagement and coaching during respiratory maneuvers and machine calibration. Another important consideration is there may be differences due to use of body box plethysmography versus helium dil...
What’s your approach to an asymptomatic, hemodynamically stable patient with moderate spontaneous pneumomediastinum without pneumothorax and normal esophagogram?
Terrific question and, fortunately, an unusual occurrence with an estimated 1 in 30,000 hospital admissions (Barroso et al., PMID 37965408). The true incidence is likely higher as underdiagnosis may be related to individuals with mild symptoms who do not seek medical care, symptoms misdiagnosed and ...
How do you approach a patient with a solitary brain metastasis from small cell lung cancer s/p resection with otherwise limited thoracic disease?
This is rather an uncommon situation but can happen if a patient presents with a synchronous solitary brain metastasis (with or w/o symptom) and undergoes craniotomy and resection only to find out that it is small cell lung cancer. Additional information is needed on the volume of intra-thoracic dis...
How do you manage daytime somnolence without a clear cause?
Throw a broad net out for the evaluation because we don't know how much has a physiological component and how much is mental/emotional. At intake, I get a moderately comprehensive set of labs. Rating Scales like HAMA, HAM-D, PHQ-9, Epworth Sleepiness Scale, and a ROS (Review of Systems) are done. I...
