What is the interpretation of two IGRAs with negative mitogen wells, in the absence of immunosuppression?
If I understand this case correctly, the patient is actively ill and the patient's doctors are considering tuberculosis as a possible etiology of the patient's illness. In that scenario, IGRAs and PPDs have a limited to no role. Epidemiology, family history, and other possible exposures do. In your ...
What are your preferred treatments for disrupted nighttime sleep in elderly patients with narcolepsy already taking sodium oxybate?
The treatment depends on what is causing the disruption. Before I consider any medication, I recommend a thorough investigation of possible causes of the disruption. For example, has sleep apnea been ruled out? Is the patient taking alerting substances close to bedtime? What is the sleep environment...
How do you manage catheter-associated, upper extremity superficial venous thrombosis?
I manage catheter-associated upper extremity superficial venous thrombosis (SVT) conservatively with arm elevation, warm compresses, NSAIDs, and topical creams containing NSAIDs. Upper extremity SVT is primarily caused by indwelling intravenous catheters, so I do strongly recommend catheter removal ...
What is your approach to treatment of airway involvement, such as recurrent bronchial stenosis, in relapsing polychondritis?
Depending on the location of airway involvement from the subglottic area to the trachea and central airways, options include cryo-spray ablation, balloon dilation, APC/Laser ablation (less favored), Kenalog injection and airway stenting. Typically, combined modalities are more effective than single ...
What factors do you consider when determining whether to perform a biopsy for the diagnosis of organizing pneumonia?
If there are known risk factors such as autoimmune disease, biopsy is usually not necessary in that circumstance. If it's truly cryptogenic in nature, or the appearance on CT imaging is not typical, then biopsy can be helpful. Direct tissue sampling also increases the yield for culture in case it is...
How often do you recommend ophthalmologic screening exams for patients with sarcoidosis?
The American Academy of Ophthalmology has guidelines for routine eye exams for an asymptomatic, healthy individual (not someone with sarcoidosis). These guidelines include a complete, dilated eye exam at age 40, interim exams at the discretion of the patient and one's ophthalmologist, and an exam ev...
How would you manage an intermediate-risk segmental PE that is transiently provoked after a knee surgery?
Segmental suggests small PE and prob intermediate-low risk. But still look at vitals, RV/LV ratio, and clot burden. Again, clot sounds small (no lobar, main PA or saddle, but look for contrast-reflux into IVC/liver. Try to look at RV FUNCTION by echo if possible, and echo also allows ruling out a cl...
How do you talk with your patients regarding radiographic expectations on surveillance CT after lung SBRT?
In general, especially when I have a discussion about the 3-month follow-up scan and tell patients that the lesion may likely be stable in size, which is often normal, and not to panic. There may also be post-radiation changes that make it more difficult to initially interpret. I think this highligh...
What are some immunosuppression regimens to consider in a patient with refractory cardiac sarcoidosis?
Unfortunately, there is no high quality data at this point to directly answer this question but here are some options. For patients who have only been treated with oral steroids, I would first consider the addition of weekly methotrexate at a dose of between 10 - 20 mg WEEKLY with supplemental folic...
When would you consider referring a patient with suspected cardiac sarcoidosis based on PET and MRI for endomyocardial biopsy given degree of patchy involvement, as opposed to initiating empiric immunosuppressive therapies?
I would avoid initiating empiric immunosuppressive therapies without a firm diagnosis of sarcoidosis. I will mention however that the latest Japanese Circulation Society criteria for the diagnosis of sarcoidosis do include criterion for the non-invasive diagnosis of likely cardiac sarcoidosis based ...
