abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...
BACKGROUND Peptide receptor radionuclide therapy (PRRT) is an effective form of treatment for patients with metastatic neuroendocrine tumors (NETs). However, delivering sufficient radiation dose to the tumor to result in a high percentage of long-term tumor remissions remains challenging because of the limits imposed on administered activity levels by radiation damage to normal tissues. The goa...
UNLABELLED Hepatic metastases of colorectal carcinoma are a leading cause of cancer-related mortality. Most colorectal liver metastases become refractory to chemotherapy and biologic agents, at which point the median overall survival declines to 4-5 mo. Radioembolization with (90)Y has been used in the salvage setting with favorable outcomes. This study reports the survival and safety outcomes ...
UNLABELLED The standard treatment of meningiomas is surgery or radiotherapy. Complex, especially recurrent or progressive cases, may exhibit tumor growth involving critical neurovascular structures or diffuse growth, resulting in limited efficacy and higher risk of standard treatment. We evaluated whether somatostatin receptor-targeted radionuclide therapy with (90)Y-DOTATOC may be a therapeuti...
UNLABELLED This investigation examined the accuracy of dose calibrator activity measurement of the beta-emitting radiopharmaceutical (90)Y-ibritumomab tiuxetan. METHODS Five different facilities independently measured (90)Y in a 10-mL syringe geometry with 30 dose calibrator models from 3 different manufacturers. The activities ranged from 81.4 MBq (2.2 mCi) to 1,406 MBq (38 mCi) over the vol...
هدف: هدف پژوهش حاضر، بررسی پایایی و روایی نسخه فارسی مقیاس وسواسی- اجباری ییل- براون (y-bocs) بود. روش: 140 بیمار مبتلا به اختلال وسواسی- اجباری (ocd)، بهعنوان گروه آزمایش و 30 فرد سالم، بهعنوان گروه گواه، بهصورت در دسترس انتخاب شدند. برای گردآوری دادهها، افزون بر y-bocs، مصاحبه بالینی ساختاریافته برای اختلالهای محور i در dsm-iv (scid-i) و خردهمقیاس وسواسی- اجباری سیاهه 90 گویهای نشانهه...
PURPOSE Radioimmunotherapy may improve the outcome of hematopoietic cell transplantation for hematologic malignancies by delivering targeted radiation to hematopoietic organs while relatively sparing nontarget organs. We evaluated the organ localization of yttrium-90-labeled anti-CD45 ((90)Y-anti-CD45) antibody in macaques, a model that had previously predicted iodine-131-labeled anti-CD45 ((13...
We examined whether a pretargeting method using a new recombinant anti-CD20 bispecific antibody (bsMAb) followed by (90)Y-1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid ((90)Y-DOTA)-peptide could reduce hematologic toxicity yet improve therapeutic responses compared with conventional (90)Y-anti-CD20 IgG and a chemically conjugated bsMAb. TF4, a humanized, tri-Fab bsMAb with two F...
Several studies have indicated that radioimmunotherapy is an effective and clinically relevant complementary therapeutic approach for patients with B-cell non-Hodgkin's lymphoma (NHL) and may convert partial to complete response when given as consolidation after induction chemotherapy. Yttrium-90((90)Y)-ibritumomab tiuxetan ((90)Y-IT, Zevalin(®), Y2B8) has documented efficacy for both indolent ...
PURPOSE Selective internal radiotherapy (SIRT) with yttrium-90 ((90)Y) resin microspheres can improve the clinical outcomes for selected patients with inoperable liver cancer. This technique involves intra-arterial delivery of β-emitting microspheres into hepatocellular carcinomas or liver metastases while sparing uninvolved structures. Its unique mode of action, including both (90)Y brachyther...
