PURPOSE The CD20 antigen is expressed on more than 90% of B-cell lymphomas. It is appealing for targeted therapy, because it does not shed or modulate. A chimeric monoclonal antibody more effectively mediates host effector functions and is itself less immunogenic than are murine antibodies. PATIENTS AND METHODS This was a multiinstitutional trial of the(More)
OBJECTIVE The authors review their initial experience with laparoscopic splenectomy in patients with hematologic diseases. Efficacy, morbidity, and mortality of the technique are presented, and other patient recovery parameters are discussed. SUMMARY BACKGROUND DATA Laparoscopic splenectomy is performed infrequently and data regarding its safety and(More)
We describe a case of low-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) arising in the liver of a patient with early-stage primary biliary cirrhosis (PBC). The patient, a 62-year old woman, presented with abnormal liver function tests, a positive antimitochondrial antibody titer (1:160), and a liver mass. The resected mass, 6.0 x 5.0 x(More)
BACKGROUND Bortezomib is active in heavily pretreated multiple myeloma patients; the dose-limiting toxicity is peripheral neuropathy (PN). METHODS The authors retrospectively reviewed the incidence, severity, and risk factors for PN in 78 patients who received bortezomib. The median age was 57 years (range, 33-80 years), 62% of patients were men, and 37%(More)
BACKGROUND Livedoid vasculopathy (LV) is an occlusive thrombotic disease that affects primarily the small blood vessels of the lower extremities and often is associated with recurrent painful ulcerations. The pathogenesis of LV is unclear, but the disease is largely attributed to a hypercoagulable state. Factor V Leiden mutation, heterozygous protein C(More)
We describe a case of severe coagulopathy after mesenteric revascularization. Laboratory investigation results revealed the presence of plasma inhibitors of factor V believed to result from exposure to bovine thrombin used for intraoperative hemostasis. Vascular and cardiothoracic surgeons commonly use topical thrombin for surgical hemostasis, and many(More)
The lupus anticoagulant, with or without other symptoms or signs of lupus, has been described in patients taking procainamide. Screening all such patients for the presence of these anticoagulants may be warranted (despite the rarity of episodes of bleeding) in view of the potentially increased risk of thrombotic events in patients who may already be(More)
Plasma infusion and/or plasma exchange has become standard therapy in the treatment of thrombotic thrombocytopenic purpura (TTP). The management of patients in whom such primary therapy fails is difficult and uncertain. We have described a patient who obtained a sustained remission with the use of high-dose IV gamma globulin after an initial response to(More)
The lower limit of normal for the platelet count is considered to be 150,000/cu mm in both pregnant and nonpregnant normal adults. In the absence of preeclampsia, sepsis, drugs, or other apparent causes, the finding of asymptomatic mild thrombocytopenia in pregnant women is compatible with previously unrecognized immune thrombocytopenic purpura (ITP).(More)
