What is the specificity of dynamic air bronchograms for bacterial pneumonia?
Dynamic air bronchograms on lung ultrasound for bacterial pneumonia have a specificity estimate around 95% (Lichtenstein et al., PMID 19225063 and Haaksma et al., PMID 34582414). This high specificity reflects the presence of patent, transiently air-filled bronchi within consolidation characteristic...
How do you suggest using POCUS to detect or confirm a pneumothorax?
Great question - yes, there are mimickers of "lung point" (known as pseudo-lung point) such as pleural-based blebs, anatomical junction between heart/lung or between two lobes, focal adhesions - to name a few. On top of this, searching for a lung point in a deteriorating patient can delay interventi...
Do you prescribe empiric antibiotics to patients with CAP who test positive for a respiratory virus?
I do not start antibiotics when there is a detected viral etiology. And I tend to stop them if they were started. Obviously, this changes if the symptoms worsen and/or I suspect a bacterial superinfection. Another caveat would be in a patient with underlying COPD where Azithromycin may play a role i...
Are there best practices for integrating pollen, wildfire smoke, and AQI data into asthma/allergic rhinitis action plans?
Living in northern Calif, we frequently incorporate this topic into our patient discussions. We advise virtually all of our asthmatic pts to have a high-quality HEPA air purifier available because they frequently become hard to get when the air quality decreases.
In suspected portopulmonary hypertension with high cardiac output where mPAP is elevated but PVR is acceptable, do you base liver transplant candidacy primarily on PVR (and RV function) rather than mPAP, and how do you operationalize that in your listing decisions?
The short answer is yes. The key parameters of PVR and right heart function by transthoracic echo (mainly RV free wall strain, Fractional area change, and TAPSE in combination) are discussed by pulmonary and anesthesia colleagues at our selection conference. Specifically, we follow the current Inter...
Under what circumstances would you initiate antibiotics in adults hospitalized with RSV and a suspected bacterial co-infection?
Bacterial co-infection in patients hospitalized with RSV ranges between 8% and 29% (Karlsen et al., PMID 41488696). The American Thoracic Society 2025 guidelines recommend prescribing empiric antibiotics to all hospitalized patients with clinical and imaging evidence of community-acquired pneumonia ...
How frequently do you monitor CT scans, PFTs, and TTEs in patients with ILA or mild ILD?
Typically, I want my patients with ILD to be seen in clinic every 3-4 months, but of course, that depends a great deal on individual circumstances (e.g., disease severity, what we're doing for their disease, etc.). My typical approach is to have my patients perform spiro, DLCO, and 6MWT Q 3-4 months...
What is your approach for a primary tracheal squamous cell carcinoma?
First off as you probably know this is a randomized data-free zone. So to some extent what to do here is empiric and/or based on historic outcomes, retrospective data, and so on. But here are a few quick & dirty observations...1) Surgical patients have the best survivals/outcomes. Doing tracheal sur...
When prescribing SMART regimen for a new diagnosis of asthma, do you still prescribe rescue inhaler (i.e. SABA) if they don't have it?
When using the SMART (single maintenance and reliever therapy), I don't add an albuterol (SABA) rescue inhaler. The whole idea is to simplify things for the patient so that they maintain their asthma control and get relief with the necessary via just one inhaler. Budesonide - formoterol combinations...
What treatment approach do you suggests for a patient with nasal polyp disease and asthma who was improved on dupilumab, but over last 2 years has begun to have increased nasal symptoms and rising eosinophil counts?
Dr. @Dr. First Last's comments are quite valuable. It might be more expedient to consider simpler options first, then progress to the less common diagnoses as needed. I very much agree that unless we know what is meant by "increased nasal symptoms", it is difficult to provide precise alternative the...
