Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
How do you approach a patient with Paget’s disease of bone with elevated alkaline phosphatase and history of chronic kidney disease?
You can give Zol IV, which is clearly the optimal treatment for active Paget's. Those in the field that treat many such patients just administer this very slowly over 1-2 hours and assure good hydration concomitantly. I have treated a number of patients like this, with this scenario, without any pro...
How do you counsel a patient with Sjogren's and extremely dry mouth who is losing their ability to taste food?
Agree with Dr. @Dr. First Last, and we cannot overemphasize the candidiasis part. Have a very low threshold for treating candidiasis while at the same time maximizing salivary stimulation (pilocarpine, cevimeline, bethanechol). When severe xerostomia occurs, as in the question, atypical presentation...
How do you treat nocturnal leg cramps?
Nocturnal leg cramps are similar to daytime leg cramps, but stretching may be less convenient to use as a remedy, as sleep can be further disrupted. Treating and preventing leg cramps typically utilizes some combination of hydration and electrolytes but sometimes, medications can help. Consider the ...
What is the clinical significance of elevated serum complement (C3 and/or C4) levels?
I have always considered elevated complement levels to be an acute phase reaction and an indication of inflammation, be it infection or cancer, similar to the ESR and CRP. Recent data have linked these elevated levels with obesity and metabolic syndrome. We have known for years that levels of C3 and...
How do you interpret significant eosinophilia in a patient with suspected granulomatosis with polyangiitis (GPA)?
This is an important question because at times the distinction between GPA and EGPA can be difficult to make. In general, I would rely on clinical symptoms as a key distinguisher. For example, sinusitis in GPA differs from that of EGPA, with the former often causing crusting, erosions/necrosis on EN...
Under what circumstances would you consider low-dose radiation therapy for osteoarthritis in an older adult patient?
Almost any and all circumstances.
Which serologic tests are most helpful when evaluating for suspected drug-induced lupus?
If I suspect drug-induced lupus, I typically order the following laboratory testing: ANA/IFA Anti-histone antibody, usually positive in drug-induced lupus Anti-Ro antibody, usually positive in drug-induced subacute cutaneous lupus Anti-dsDNA, usually negative in drug-induced lupus vs positive in id...
What is your treatment approach for pregnant patients with IgA nephropathy who have worsening proteinuria during the first trimester?
Difficult question to answer without more details, but I would consider the following factors: One is whether it appears that the IgA is active. When was the last biopsy, and how much hematuria is present? Two would be if this is 'worsening proteinuria' is really just the first time proteinuria has ...
When do you consider genetic testing for autoinflammatory diseases in patients with recurrent pericarditis and fever, particularly when symptoms are highly responsive to IL-1 blockade?
Yesterday ;-). About 10% of patients with recurrent pericarditis have genes that may increase their risk of pericarditis. If you're already managing the patient with IL-1 inhibition, I would strongly encourage you to conduct genetic testing. Just my 2 cents...
