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...
How do you counsel patients with RA stable on csDMARDs on whether to attempt tapering or not?
It is important to recognize that this counseling is highly individualized and that factors such as risks of medication toxicity, age, comorbidities and disease severity all play a part. However, several studies have demonstrated a significantly increased risk of RA flares and radiographic progressi...
What treatment combination approach would you recommend for mucous membrane pemphigoid?
First, it is important to know the extent and severity of the disease (oral, ocular, esophageal); the type of inflammatory infiltrate on histopathology (neutrophils, eosinophils, or cell-poor); and the results of salt split skin and antibody titers on monkey esophagus and/or target antigens (collage...
How do you approach the management of mild to moderate tics induced by stimulants in children?
If dose reduction or medication switch is not possible, first-line treatment includes adding an alpha agonist like guanfacine or clonidine. I prefer guanfacine as clonidine is more sedating and less tolerated by kids. CBIT (Comprehensive Behavioral Interventions for Tics) would be great but hard to ...
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...
How do you choose among SSRIs and dosing strategies for the management of behavioral and psychological symptoms of dementia?
The best supported SSRI for BPSD generally is citalopram. Much of this came out of the CitAD trials [1]. This primarily showed citalopram may be useful for hyperactive behaviors, irritation, but also for depression and anxiety [1, 2]. The effect and response to citalopram, though, may be affected by...
Should CT coronary calcium score be avoided in dialysis patients in light of presumed high prevalence of CAC in this population?
The incidence of coronary calcifications in patients on dialysis exceeds 80% and is between 50-80% in patients with CKD. In addition, dialysis and ESRD cause two types of vascular calcification - in the medial and intimal layers, the latter being the one that correlates best with atherosclerotic pla...
What is your approach to isolated alkaline phosphatase without other laboratory abnormalities?
Assuming none of the other LFTs are abnormal, I would get a GGT. If GGT is elevated --> likely a hepatobiliary issue. Would consider age, medical history, and risk factors. If persistently elevated, could consider RUQ US + MRCP. Conditions like PSC or PBC are frequently discovered due to asymptomati...
How do you address mental health and online presence with teenage patients?
There are four variables that I talk to parents/teens about: Volume of screen exposure; low vs high. There is some data that pure volume is a risk factor, but not uniformly so. Psychiatric vulnerability; low vs high. Some kids are more vulnerable (e.g., social and generalized anxiety disorder and d...
