How do you approach management of a patient with multiple lung nodules and low titer +CCP but no active joint symptoms suggestive of RA?
In the absence of other clinical symptomatology, I would favor close observation and follow-up in this case as there is no established diagnosis and repeat CT, PFT’s in 3 to 6 months. Details of initial evaluation should include PET-CT to exclude malignancy but also to investigate other organ system...
How do you screen rheumatoid arthritis patients for lung disease (modality, frequency, patient selection)?
Theoretically, we are supposed to screen these patients obtaining a baseline chest X-ray before starting DMARD therapy. As I remember, these guidelines were formulated when MTX was still blamed for MTX lung disease although presently, even the presence of underlying ILD is not necessarily a contrain...
Do you recommend procalcitonin to help convince other providers to stop antibiotics in patients with pneumonia in whom a non-infectious diagnosis is strongly suspected?
I have looked at both of these studies in some depth. The de Jong et al., study, called SAPS, is perhaps the more impressive of the two, but regarding either or any study on so-called "biomarkers", even the RCT studies only make recommendations or give advice. And, more often than not, the doctors d...
How do you workup patients with neuropathy suspected to be secondary to sarcoid?
To answer this question, the attached paper with consensus criteria for the diagnosis of neurosarcoidosis, published in 2018, should be reviewed, Stern et al., PMID 30167654.Based on this paper, a diagnosis of probable or definite neurosarcoidosis requires unequivocal evidence of non-caseating granu...
Is there an upper threshold of pCO₂ that can cause symptomatic hypercapnia (e.g. AMS) despite metabolic compensation and normal pH?
Hi - I'm not sure about an upper threshold of pCO2 and AMS. However, even with normal pH, elevated pCO2 can cause significant increases in cerebral blood flow. Pollock et al., PMID 19406361 studied MR perfusion imaging and found that patients with a mean pCO2 of ~ 54mmHg had more than double the cer...
What is your pharmacologic approach to treating insomnia comorbid with sleep apnea?
I do not usually treat any insomnia, regardless of comorbidities, with any targeted medication for the insomnia itself. If the patient is getting over 5 hours of sleep, then I use CBT-I as this is guideline-recommended (AASM) first-line treatment for insomnia and has efficacy lasting over a year out...
Are you more permissive of perioperative interruption of anticoagulation for VTE depending on the location and relative chronicity of the thrombus?
Yes - in general, I try to balance the relative urgency/importance of the procedure or surgery v. the thrombotic risk to the patient of a period of time off of anticoagulation. Location and chronicity both can feed into determining thrombotic risk. An upper extremity DVT, in general, has a lower rec...
What is your experience with transesophageal lung mass biopsies?
Thoracic lesions requiring FNA in the mediastinum are often best approached with EUS–FNA, as the sedation and airway management are less complex than the EBUS, and the needle does not need to break through cartilage rings to access the lesion. On the other hand, a lung mass would require the needle ...
What is your approach to managing hyperkalemia secondary to respiratory acidosis?
Since hyperkalemia in respiratory acidosis is due to transcellular shift, therapy should be directed at treating the underlying respiratory acidosis. Correction of the hypercarbia should lead to resolution of the hyperkalemia. In severe hyperkalemia due to respiratory acidosis that is not easily rev...
How do you or your practice manage young, average-risk patients without structural lung disease referred to you or self-referred for concern of environmental mold exposure?
These individuals are generally managed by pulmonology and allergy/immunology clinics because the clinical presentation is generally more aligned with allergy-type symptoms like a chronic cough, congestion, or other symptoms associated with airway irritation. In individuals who are receiving chronic...
