Would you treat Scedosporium growth in expectorated sputum in a patient with COPD, pulmonary hypertension, and bronchiectasis, who has chronic dyspnea with exertion, thick sputum production, negative bacterial cultures, and no signs of mold infection on a high resolution CT scan, with no other clinical symptoms of infection?
In persons with bronchiectasis, almost anything that grows can be a pathogen, but it is tough to know. If the patient has COPD and no other immunocompromising conditions, I would not expect typical invasive fungal infection findings. Having said that, scedosporium is not the first common pathogen th...
How do you manage anticoagulation for patients with DVT/PE who have brain metastases?
Not all brain metastases pose the same risk to patients. Rapid, numerous (even if tiny), new onset metastases from RCC or melanoma (especially BRAF mutant) can go from asymptomatic to life threatening hemorrhage within 1-2 weeks and I would strongly caution anti-coagulation in these patients. If the...
How do you approach a positive Quantiferon/PPD test result in a patient for whom testing is sent without a clinical indication and who does not have a risk factor for TB exposure nor TB reactivation?
If a test for TB infection such as a Quantiferon or PPD is done without TB exposure risk factor or clincial indication and is positive, a chest X-ray and good history for symptom assessment and exam should be done. I will assess to see if there is an increased risk of developing TB such as an immuno...
What factors influence your decision between dexmedetomidine and propofol for sedation in mechanically ventilated patients?
The main factor that influences this decision in my practice is the indication for mechanical ventilation. For patients in whom the main indication is airway protection, such that the patient would not otherwise require oxygenation or ventilation support, I aim for higher RASS goals (-1 to +1) and t...
How do you manage a 3 cm solitary pulmonary cryptococcoma in an asymptomatic, immunocompetent, HIV-negative host?
I will treat it with oral Fluconazole for 6-12 months. Brain MRI to R/O CNS infection.
What policies do you take regarding legalized recreational marijuana or medical marijuana use in transplant patients?
The use of THC and CBD is becoming an increasingly important topic in solid organ transplantation. Recent survey data has demonstrated that daily cannabis use is higher than daily alcohol use in the U.S. (Caulkins, PMID 38775461).Certainly, the legalization of THC use in many states has led to consi...
How soon would you repeat PET/CT in a patient with cardiac sarcoid after starting treatment with infliximab?
Very good question. There is no consensus on this answer, and it is also important to consider the medical burden on a patient to repeat such involved testing. Our approach is to follow the resolution/improvement of patient-reported cardiac-related symptoms and follow less invasive testing such as E...
How do you decide on supportive care vs empiric antibiotics in a patient with suspected aspiration pneumonitis (i.e., witnessed macroaspiration event within the past 24 hours) but with features that could suggest pneumonia (e.g., acute respiratory distress, fever, leukocytosis, pulmonary infiltrates, etc.)?
Great question and one that comes up all the time for me. As the patient has more signs of true infection, such as those you mention with fever, leukocytosis, and respiratory distress, I am much more likely to start antibiotics. If the patient just has chest radiograph findings of opacities and some...
How do you approach managing clozapine in patients who are critically ill?
With COVID-19 disproportionately affecting those with mental illness we found an increasing number of medical admissions for those on clozapine. There are multiple domains of concern for those on clozapine who are medically ill. Clozapine levels have been shown to potentially double during periods o...
How do you use cardiac POCUS to potentially defer formal echocardiogram in patients presenting with an acute pulmonary embolism?
In patients with acute PE, cardiac ultrasound is useful in risk stratification and identification of patients at higher risk of short-term mortality and complications. Signs to look for on POCUS are: RV dilatation (RV>LV on apical 4-chamber view), McConnell Sign (hyperkinetic RV apex with hypokineti...
