How would you approach treatment of latent TB for patients who cannot tolerate rifamycins or isoniazid due to allergy, intolerance, or drug-drug interactions?
Levofloxacin or moxifloxacin. Duration is 6-9 months.
When do you consider diaphragmatic pacing in patients with diaphragmatic paresis?
Diaphragmatic pacing and phrenic nerve stimulation are most typically considered in patients with chronic ventilatory failure that results from high cervical spine or brain lesions that disrupt the normal respiratory drive pathways that exist within the pons and medulla. It is also commonly used in ...
Do you favor aggressive airway clearance regimens or bronchoscopy for clearing occluding mucous plugs in patients who are not in respiratory distress?
The first step is to determine the cause of the secretion issue. Is this acute or chronic? The underlying disorder that predisposes to abnormal mucus or ineffective cough? How much difficulty is this creating with ventilation and or oxygenation (ir level of urgency?). Since there is no respiratory d...
Do you recommend providing supplemental oxygen for patients with a pneumothorax in the absence of hypoxemia?
I was certainly always taught that one should give supplemental oxygen to patients to decrease the size of the pneumothorax. This is based on the "nitrogen wash-out" theory, essentially, you're trying to get the partial pressure of nitrogen down in the alveoli so that it will be resorbed from the pn...
Do you use an antibiotic with antitoxin activity for the entire duration of therapy for patients with necrotizing MSSA or MRSA pneumonia or just until definitive clinical improvement?
I misread the question. I assumed a necrotizing S. aureus infection meant a necrotizing skin and soft-tissue infection. I’m not sure how “necrotizing pneumonia” is being defined here. Regarding MRSA pneumonia with toxin-mediated tissue injury, there are data suggesting that linezolid may yield bette...
How has the FLUID trial, which showed no significant difference in death or readmission rates between Lactated Ringer’s solution and normal saline, influenced your approach to IV fluid management?
The choice between normal saline and Lactated Ringer's should be individualized. Normal saline is preferred in patients with hyponatremia or metabolic alkalosis. Lactated Ringer's is preferred in patients with hyperchloremic acidosis, and it should be avoided in patients with hyponatremia since its ...
How do you weigh the risk of urinary catheter or fecal management system placement with that of soiling sacral wounds?
This question is an important question that arises for many of our bed-bound and poorly mobile patients, as sacral wounds commonly develop due to pressure injury. They become very challenging to treat due to fecal and urinary contamination, which can lead to further infection. Fecal and urinary dive...
Would you stop Dupixent in an asthma patient who has good asthma control and notes improvement in loss of smell, but shows notable eosinophil elevation after 4-5 doses of the medication?
Transient eosinophilia has been reported in patients treated with Dupixent, likely related to downregulation of eotaxin and adhesion molecules resulting in impaired eosinophil migration into the tissues (Castro et al., PMID 29782217, Olaguibel et al., PMID 35522053). This phenomenon is typically see...
How have the findings from DanGer Shock RCT changed your perspective on which patients presenting with acute MI complicated by cardiogenic shock would benefit from Impella for additional hemodynamic support?
First and foremost, it is notable that DanGer Shock (Møller et al., PMID 38587239) was the first randomized trial to show a mortality benefit with the use of a microaxial flow pump in acute MI-associated cardiogenic shock - a practice that proliferated based upon promising outcomes in non-randomized...
When would you recommend prescribing an asthmatic patient budesonide/salbutamol rather than budesonide/formoterol?
This is another example of two approaches to the same issue (i.e. adding inhaled steroid to a rescue B2 adrenergic agent) which is actually more theoretical than practical since no head-to-head studies have been reported. For me, there is an intrinsic value to using a rapid onset LABA (i.e. formoter...
