How well does a negative non-contrast MRI of the brain exclude metastasis in a patient with squamous cell carcinoma of the lung?
I don't think the question has enough information to give a good answer. For example, if it was a T3, N2 NSCLC, or a small cell, then "yes" I'd repeat the MRI with contrast. On the other hand, if it was a T1, N0 NSCLC, then "no", I wouldn't. In other words, if I thought there was a real risk of havi...
What steroid durations do you use for the treatment of acute, chronic, and drug-induced eosinophilic pneumonia?
For acute eosinophilic pneumonia, these are often high doses of IV methyl prednisone in the hospital, and assuming that the exposure or risk is mitigated, I would taper these down over a short period of time after discharge. Chronic eosinophilic pneumonia, I treat briefly with steroids but quickly t...
What specific clinical and echocardiographic thresholds lead you to taper/de-escalate pulmonary hypertension therapy before liver transplant?
The goal in pulmonary hypertension therapy pre-transplant is to fulfill the MELD exception criteria in terms of mean pulmonary artery pressure, pulmonary vascular resistance, as well as right ventricular function by echo. Once those criteria are satisfied, maintain those PH therapy doses until the t...
What is your approach to empiric treatment of achromobacter infections?
Achromobacter is a Gram-negative bacterium in the Burkholderia order. This pathogen is significant in immunocompromised patients, such as those with cancer or Cystic fibrosis, and is seen with bacteremia or causing pneumonia. They can also be associated with foreign device infections. Typically, the...
Would you consider leaving fever untreated in patients with sepsis to potentially enhance immune responses and antimicrobial efficacy?
In light of the review article attached (Tilanus et al., PMID 41113323), there is some data reviewed supporting that fever is actually therapeutic. Four articles are of special interest in the review. Two are from the 70s, before sepsis was defined as it is today. Two are in the last 15 years, but o...
Do you generally recommend device exchange/removal in patients with gram positive bacteremia in the setting of intra-aortic balloon bump or other mechanical circulatory devices?
I am assuming in this case that the patient has a mechanical circulatory support device such as an LVAD, IABP, or another implantable device, and has developed gram-positive bacteremia. No further details about the device type or clinical scenario are provided. In such cases, device removal is recom...
Do you recommend doxycycline over azithromycin as first-line treatment for outpatient community-acquired pneumonia in otherwise healthy adults, given rising macrolide resistance rates?
Yes - our county antibiogram shows >50% resistance of Streptococcus pneumoniae to azithromycin, and thus if there is a true concern for bacterial infection, I recommend doxycycline.
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 elevated neutrophils in the bronchoalveolar lavage of patients with sarcoidosis have any prognostic value?
Neutrophils in the alveolar space are uncommon in healthy non-smoking individuals, accounting for around 1% of cells in bronchoalveolar lavage (BAL). Macrophages compose 80–90% of the cells policing the alveolar surface, with the remaining cells being lymphocytes, rare eosinophils, and basophils. A ...
How do you manage moderately severe RLS in a patient with advanced CKD (eGFR 15–30) who has developed dopaminergic augmentation on a dopamine agonist, given that standard gabapentinoid replacement agents carry significant accumulation risk at this level of renal impairment?
This is a challenging picture. I suggest slow tapering of the dopamine agonist while proceeding to the next therapy. I propose the following steps. Check ferritin/TSAT → give iron if low, IV iron may be needed. Start low-dose gabapentin or pregabalin (renal dosing). Titrate cautiously. Severe persis...
