For opiate-related ileus in the postoperative setting, at what point do you consider trialing methylnaltrexone?
I personally have never used this particular PAMORA for post-op ileus. Despite some promising phase 2 trials indicating potential benefit, several Phase 3 RCTs evaluating this drug specifically for post-operative ileus showed no benefit in preventing nausea/vomiting or speeding up time to discharge ...
Would you biopsy calcified lung nodules and or lymphadenopathy that have shown stability over a 2-year period, in a bid to rule out sarcoidosis?
No. Certainly not without a comprehensive occupational and other exposure history. Follow "the rules" for the assessment of any sarcoidosis suspect. Do a physical exam to look for extrapulmonary signs of sarcoidosis. Order an eye exam to assess for ocular sarcoidosis. Obtain baseline MTB testing and...
How soon after a fracture would it be safe to start anti-resorptive therapy?
This is an important question. There is no definitive answer, and there have been no clinical or preclinical studies that demonstrate delayed healing in the presence of bisphosphonates. Personally, I favor waiting a few weeks before we start. That also gives us time to do a proper metabolic workup. ...
When do you check vitamin D levels in patients with depressive symptoms?
I routinely check 25-OH D in all my patients. Given that half the population is deficient and that we now know the role of vitamin D not only for bones but in mood, cognition, and immunity. We need to be aware of deficiencies and replete if low. Moreover, ideal levels are 60-80, not just over 29 as ...
Under what circumstances would you consider treating obstructive sleep apnea in an older adult who has few or no daytime symptoms?
I always treat OSA if severe with respect to the level of hypoxemia or of fragmentation of sleep (which can be approximated by the AHI). Even if there are no symptoms of daytime sleepiness, I would treat it if there are nighttime symptoms (e.g., middle-of-the-night insomnia, nocturia, or waking too ...
What criteria do you use to determine fitness to resume driving following recovery from delirium in an older adult patient?
There are no validated delirium-specific criteria for determining fitness to resume driving. In general, driving should be deferred until the delirium has resolved and the patient has substantially recovered toward their cognitive and functional baseline. Assessment should include attention and cogn...
What is your approach to radiographically suspicious lung nodules for which initial biopsy was negative for malignancy?
It depends on how suspicious the nodule is for malignancy clinically and on the biopsy. The following criteria play into my decision-making: If the kinetics (steady growth over multiple scans) and morphology (solid and spiculated) on CT as well as hypermetabolism on PET-CT are highly suggestive of ...
Is there a role for dual antibiotic treatment with ethambutol and macrolide only, as opposed to three-drug antibiotic therapy, in the treatment of treatment-naive pulmonary MAC without cavitary disease?
That is a great question, as the role of rifampin (or rifabutin) regarding its relative contribution to the treatment of MAC is not overly clear. Historic data that is a few decades old raised the possibility of better activity when a rifamycin is combined with ethambutol (at least in vitro and furt...
When do you consider tapering tocilizumab in patients with GCA in remission?
This is a timely question and recent data sheds some light on this important topic. The risk of GCA relapse is approximately 50% (Mainbourg et al., PMID 30951256) in all comers. The GIACTA trial (Stone et al., PMID 28745999) utilized a one-year course of TCZ. A recent publication of the extension ph...
What is your approach to checking preoperative cardiac biomarkers such as troponin and BNP?
While now recommended as a means of risk stratification for those over 65 years with cardiac risk factors across all three guidelines (AHA/ACC, CCS, ESC), we mostly reserve the use of biomarkers preoperatively for patients in whom we are on the fence for obtaining additional cardiac workup. We view ...
