What is your approach to IV fluid resuscitation during a sickle cell vaso-occlusive crisis?
My approach to IV fluid resuscitation in vaso-occlusive crisis is cautious and individualized. Adequate hydration is important to prevent further sickling, but I avoid aggressive fluid loading because of the risks of pulmonary edema and acute chest syndrome. I typically use isotonic balanced crystal...
In a pregnant patient with PNH without aplastic anemia who has residual hemolysis while on ravulizumab and on prophylactic LMWH, what else can be done to reduce thrombotic risk and improve maternofetal outcomes?
Personally, I feel that C5 inhibitors are now close to obsolete in the management of PNH, since C3 and factor B inhibitors are more effective and inhibit both intravascular and extravascular hemolysis. Whether or not to use pegcetacoplan or iptacopan depends on the trimester, the seriousness of the ...
How do you manage anticoagulation for patients with DVT/PE who have brain metastases?
Not all brain metastases pose the same risk to patients. Rapid, numerous (even if tiny), new onset metastases from RCC or melanoma (especially BRAF mutant) can go from asymptomatic to life threatening hemorrhage within 1-2 weeks and I would strongly caution anti-coagulation in these patients. If the...

How would you approach anticoagulation for a newly recurrent VTE on progestin-only therapy?
Would you consider this recurrence event hormonally induced and discontinue transdermal progestin, or would you consider this an unprovoked event? I would likely consider this an unprovoked event, as the provoking factor of transdermal progesterone should be extremely weak, if at all. Would you c...
When following current COG ALL protocols with the addition of two courses of blinatumomab to treatment for SR and HR patients, how frequently should surveillance bone marrow and MRD evaluations be performed?
With the caveat that I only treat adults, but the general concepts are similar:In our practice, we routinely do bone marrow exams with MRD assessment after the first cycle of blinatumomab. Assuming this shows no detectable disease, we typically will then perform the same before transitioning to main...
Is there any benefit to changing a monoclonal EGFR inhibitor therapy when one had to be stopped for cutaneous toxicity?
The two anti-EGFR monoclonals both have high rates of cutaneous toxicity. It isn't clear that one is better than the other, so switching Is not a good option. It is better to reduce the dose and treat through with doxycycline and steroids. Generally the rash will improve within 4-6 weeks. In the cas...
Do you use premedications (acetaminophen, diphenhydramine) before pRBC and plt transfusions to prevent febrile nonhemolytic transfusion reactions and allergic reactions?
I do not routinely premedicate patients. There is a recent meta-analysis that shows no benefit. I only premedicate those who have had a prior transfusion reaction. Old studies showed this was a common practice but those studies were performed before universal leukoreduction and other strategies aimi...

How do you define cisplatin ineligibility for muscle invasive bladder cancer?
We traditionally have been using the "Galsky criteria" published in 2011 based on consensus. We have looked into possibly lower threshold for estimated GFR, e.g. 50 ml/min, and possibly cisplatin "split dose" on a per patient basis if otherwise a patient is fit: Koshkin et al., PMID 29576445.Sometim...
