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...
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...
When starting stress dose steroids for patient with primary adrenal insufficiency, how do you decide whether to start hydrocortisone 100 mg every 8 hours versus 50 mg every 6 hours?
Stress doses of steroids in patients with primary adrenal insufficiency depend on the anticipated stress. The dose of steroids can be doubled or tripled depending on the stress. For example, in cases of maximal stress such as major surgery, the dose can be similar to the dose used for an adrenal cri...
Would you recommend empiric coverage for vancomycin-resistance enterococcus in an unstable patient with sepsis, multiple comorbidities, and a recent ICU stay in a high VRE prevalence unit, despite recent cultures without growth of VRE?
I would go back to the assessment of community onset vs hospital onset as to when the sepsis is "setting in." If patient is coming from the community, hasn't had antibiotics in the last 90 days, hospitalized in the last 90 days, has no positive microbiology for VRE in the last year, then no, I would...
Are there certain clinical features that help you choose between benralizumab and mepolizumab for EGPA in clinical practice?
Given, as noted above, no significant clinical differences between benralizumab and mepolizumab, assuming there are no specific insurance differences between the two, I preferentially prescribe benralizumab because of the 8-week dosing frequency after the first three 4-week loading doses. For a few ...
How do you approach pre-operative risk assessment and optimization in a patient with interstitial lung disease?
Surgery in patients with interstitial lung disease (ILD) is not a decision we take lightly! At our center, we start with general risk tools like the ARISCAT score but layer in ILD-specific factors—such as DLCO below 60% and declining trends in PFTs or 6MWT testing. We also screen for comorbidities l...
What is your approach to tapering anesthetic drips for refractory status epilepticus after achieving burst suppression?
Ensure adequate oral/IV ASMs are on board, targeting the receptors appropriately based on the type of status- generalized, focal (e.g., GABA, Na channel, glutamate, etc.). These would include the first, second, and third line as per status protocols. Check levels to ensure adequacy. At least 24 hou...
What do you think about using conventional thoracic imaging methods (e.g., X-ray, CT, etc.) to determine if a pleural effusion is of adequate size to consider thoracentesis?
Generally speaking, CT would be superior as it would allow you to see more volumetric characteristics of the effusion; XR would have a hard time discerning true size, presence of loculations, or trapped lung. The real winner for this application would be bedside ultrasound. This modality would give ...
