BACKGROUND & AIMS Although the adenoma detection rate is used as a measure of colonoscopy quality, there are limited data on the quality of endoscopic resection of detected adenomas. We determined the rate of incompletely resected neoplastic polyps in clinical practice. METHODS We performed a prospective study on 1427 patients who underwent colonoscopy at(More)
Thromboembolism is not uncommon in multiple myeloma (MM) patients on treatment, but its pathogenesis remains poorly understood. We report the results of a prospective randomized trial of 62 newly diagnosed MM patients tested at baseline for hypercoagulability and treated with intensive chemotherapy with or without thalidomide in a randomized fashion. During(More)
BACKGROUND Remote manipulation of wireless capsule endoscopes might improve diagnostic accuracy and facilitate therapy. OBJECTIVE To test a new capsule-manipulation system. SETTING University hospital. DESIGN AND INTERVENTIONS A first-in-human study tested a new magnetic maneuverable wireless capsule in a volunteer. A wireless capsule endoscope was(More)
BACKGROUND & AIMS The aim of this study was to see if a 170 degrees angle of view (wide angle [WA]) colonoscope allowed faster withdrawal without decreasing adenoma detection. METHODS Eight colonoscopists at 2 institutions participated in the study. Patients were randomized so that each colonoscopist performed 50% of the exams with a 160 series (140(More)
Haematopoietic growth factors, especially granulocyte colony-stimulating factor (G-CSF), are frequently utilized alone for peripheral blood stem cell (PBSC) procurement to avoid the morbidity associated with high-dose chemotherapy (HDT). Moreover, the cytotoxic agents used may not be the most optimal therapy for the malignancy. It also makes scheduling of(More)
Arsenic has been used since ancient times as a therapeutic agent. However, until recently its use in modern medicine has been restricted to the treatment of a limited number of parasitic infections. In the early 1990s, reports from China described impressive results with arsenic trioxide in patients with de novo, relapsed, and refractory acute promyelocytic(More)
Lansoprazole is a potent proton pump inhibitor that has been well tolerated with minimal serious adverse events. One of the most commonly reported side effects is diarrhea in 3-8% of study patients. During 1997, approximately 850 veterans at our institution had their proton pump inhibitor converted from omeprazole to lansoprazole because of a formulary(More)
Standard allogeneic stem cell transplant (allo-SCT) regimens have been associated with a high transplant-related mortality (TRM) in multiple myeloma (MM). Nonmyeloablative therapy can establish stable engraftment after allo-SCT and maintain the antitumor effect with less toxicity, which is important in heavily pretreated and elderly patients. We report on(More)
Given the rising epidemics of obesity and metabolic syndrome, nonalcoholic steatohepatitis (NASH) is now the most common cause of liver disease in the developed world. Effective treatment for NASH, either to reverse or prevent the progression of hepatic fibrosis, is currently lacking. To define the predictors associated with improved hepatic fibrosis in(More)
