What duration of dual antiplatelet therapy do you use for secondary prevention of ischemic stroke due to intracranial atherosclerotic disease?
It is a fair question that we don't have a solid evidence-based answer for. I agree that the SAMMPRIS trial was driven by events within the first 30 days, although this was primarily driven by procedure-related events in the stented group. We do know that intracranial athero (ICAS) risk of stroke re...
What is the right approach in terms of GDMT and device consideration for patients with intermittent LBBB (QRS duration exceeding 150ms) and HFrEF?
I would not consider an intermittent left bundle as criteria for BiV pacing. I would actually not consider it in my assessment of heart failure gdmt or device therapy in isolation, whatsoever.
When can abdominal surgery be safely performed for presumptive ovarian cancer in a patient with recent pulmonary emboli?
In general, the standard approach is to try to wait as long as possible after the thrombotic event, at the very least three months. This may not be possible, we then reduce that time interval to one month. Given the urgent nature of the surgical intervention, one approach is to wait one month and co...
Do you diagnose obstruction by the criteria of FEV1/FVC < 70% or < LLN?
Using lower limit of normal for FEV1/FVC ratio may reduce misclassification of airway obstruction but despite years of discussion and arguments it remains unclear whether it is a better approach. The simplicity of the fixed ratio approach to me remains a very important consideration and it is the ap...
What is the indication for phlebotomy in compound heterozygous hemochromatosis?
The indication for phlebotomy is proven or strongly suspected iron overload. The likelihood of expression in these individuals is low. An elevated ferritin is often due to reasons other than iron overload such as fatty liver or alcohol intake. I usually do a liver ultrasound in this circumstance. If...
In SIADH due to malignancy, do you prefer to use free water restriction or salt tablets?
Fluid restriction is usually the first line measure in chronic SIADH. Salt tablets only work at high doses, as SIADH is a water, not a salt problem, and you improve sodium only minimally. Tolvaptan is a very powerful drug, but, as per the package insert, must be started in an inpatient setting. Addi...
How would you work up and manage persistent lymphopenia in an asymptomatic patient?
Simple answer: refer to an immunologist, as this degree of lymphopenia is quite likely to represent a serious immunodeficiency. I would also send a next generation sequencing panel of immunodeficiency/immunoregulatory genes to be in process while awaiting the immunology consultation. Long answer (fr...
Is there utility in monitoring IgE levels in patients with IgG4-RD?
Serum IgE levels are associated with disease extent/severity and risk of relapse in patients with IgG4-RD. In some patients (although this is not true for all patients), IgE decreases following treatment and increases with disease flares. However, some patients who have extreme IgE elevations at bas...
Do you stop tolvaptan below a certain eGFR in a patient with autosomal dominant polycystic kidney disease?
In general, the practical guidelines support continuing tolvaptan until dialysis or transplant (Chebib and Torres, PMID 33705818). There are situations where I will discontinue sooner, either due to apparent lack of benefit, due to precipitous, unexpectedly rapid decline or accelerated decline, or, ...
Given that there are a fair number of myocarditis cases without a troponin elevation, how do you clinically approach the diagnosis of myocarditis?
If clinical suspicion for myocarditis is not based on elevated troponin there needs to be some objective evidence for it. These would be CRP/sed rate/cardiac MR/biopsy. Unlikely to pursue the last step if the first three are all normal.
