Would you consider prophylactic anticoagulation for May-Thurner syndrome in pregnancy if prior endovascular intervention has been completed?
In general, I have a very low threshold to initiate prophylactic anticoagulation in pregnancy. For a patient with a history of May-Thurner that has been endovascularly corrected and who has been maintained off of anticoagulation without issue, I would have a risk-benefit discussion about prophylacti...
How long would you anticoagulate a patient with recurrent VTE who has ongoing risk factors for intracranial bleeding?
In general, my preferred agent outside of the inpatient setting in patients with a risk of intracranial bleeding is LMWH. In the inpatient setting, utilizing a bivalirudin or heparin gtt is most appropriate. I would monitor carefully, including potentially imaging 24 hours after the therapeutic anti...
Would you stop current immunosuppressive therapy or delay starting immunosuppressive therapy in a patient with aplastic anemia who has been infected with COVID-19?
Not much is known yet about this specific situation—but our growing experience here in New York City suggests it may be safe. We have had several post-BMT patients who were on immune suppression for GVHD become COVID positive who have not had significant problems. Also, we have now treated 8-10 pat...
Can RT to non-bulky sites be omitted in an early stage (stage I or II) classical Hodgkin's lymphoma case with a CR by PET/CT?
Randomized studies have consistently demonstrated that combined modality therapy is superior to chemotherapy alone in regards to progression-free survival in early-stage Hodgkin lymphoma. The magnitude of the benefit varies across studies, but a relative risk reduction of ~50% can be expected which ...
Is it necessary to prescribe a steroid taper after two weeks of high-dose prednisone (60 mg daily)?
Interesting question. Not being an endocrinologist, I don't have the expertise to advise but the reference below makes the statement that even short-term steroids can be an issue. I suspect that if you have to stop abruptly from 60 mg daily for 2 weeks, it would probably be fine in most instances bu...
How would you manage a young patient with Sjogrens disease with extranodal marginal zone lymphoma involving bilateral parotid glands with bilateral cervical lymphadenopathy?
For patients with low-grade NHLs (e.g., follicular lymphoma, marginal zone lymphoma), staging dictates treatment. If a patient has a localized process (e.g., contiguous stage I-II disease), then a definitive course of RT is typically recommended. The conventional approach is 24-30 Gy, though a dose-...
Could patients with smIPI > 1 and poor tolerability to RCHOP be offered ISRT after 3 cycles of RCHOP if interim PET showed 5-PS 1-3 response?
The FLYER and LYSA/GOELAMS studies have significantly influenced the management of DLBCL. Although the studies were quite different, they both demonstrated that patients with non-bulky, stage I-II DLBCL and a favorable IPI do very well with 4 cycles of R-CHOP alone. For patients with 0 or 1 stage-mo...
How do you decide when to pursue malignancy workup for patients with cryptogenic stroke?
Agree with above. I would also pursue malignancy work-up in this scenario as well: currently on anticoagulation (whether for afib or another medical reason) and has an ischemic stroke on top of that.
For pediatric patients with iron overload (high ferritin and transferrin saturation), do you perform HFE screening first, or proceed to non-HFE gene sequencing upfront to evaluate for HJV mutation as well?
Because there is no recommended "screening" scenario for iron overload in pediatrics (especially with no family history), the question for me revolves around "why did the patient get tested in the first place?" If it were a routine screen for iron deficiency, which affects millions of children at an...
How do you manage perioperative anticoagulation for a patient with a history of recent, surgically provoked VTE?
In most cases, bridging is rarely indicated because the bleeding risk usually outweighs the risk of VTE recurrence during a short (1–2 day) interruption of anticoagulation. However, after a recent VTE (defined as <3 months), the estimated risk of VTE recurrence is high (>15–20% per year) (still low ...
