Three hundred twenty-four percutaneous inferior vena caval (IVC) filters of different designs were placed in 320 patients from April 1985 through June 1992. No acute mortality or substantial morbidity was attributed to filter placement. Radiologic or pathologic follow-up data were obtained in 227 (71%) patients (230 filters); clinical follow-up data only(More)
Simon nitinol vena caval filters were placed percutaneously in 20 patients. Follow-up (average, 14 months) data were available for 16 patients, and four patients were lost to follow-up. There were no proved or suspected cases of pulmonary embolism after filter insertion. Complications encountered included caval penetration (n = 5, one acute and four at(More)
Erythromycin resistance in Campylobacter coli from meat animals is frequently encountered and could represent a substantial barrier to antibiotic treatment of human infections. Erythromycin resistance in this organism has been associated with a point mutation (A2075G) in the 23S rRNA gene. However, the mechanisms responsible for possible dissemination of(More)
One hundred one LG-Medical (LGM) vena cava filters were placed in 97 patients at four institutions. Placement was a complete technical success in 90% (91 of 101). In 6% of attempts, LGM filter insertion was complicated by incomplete opening of the filter. Pulmonary embolism after filter placement was not definitely demonstrated in any patient. The(More)
We examined alterations in the p53 tumor suppressor gene and the ras and HER-2/neu oncogenes in chicken ovarian cancers to determine if these tumors have genetic alterations similar to those in human ovarian adenocarcinomas. Mutations in the p53 tumor suppressor gene and the H-ras and K-ras oncogenes were assessed by direct sequencing in 172 ovarian cancers(More)
Flock records from a commercial turkey company were analyzed to determine if poult source affected flock performance. Comparisons were made between flocks supplied by two hatcheries (X and Y) reared on the same farms and among flocks reared on different farms. Flocks from hatchery X had significantly better livability and feed-conversion ratios than flocks(More)
Vena caval filter placement via the right external jugular vein was attempted in 13 cases. Eleven percutaneous vena caval filters of four types were successfully placed in the inferior vena cava. Two of the attempts were unsuccessful. The indications for the external jugular vein approach were obstructive lower-extremity deep venous thrombosis in eight(More)
Amplatz vena caval filters were inserted percutaneously in 30 patients. Radiologic and clinical follow-up was available in 24 patients (cavogram, CT, or sonography in 20 patients, plain abdominal radiographs in two, and lower extremity venograms in two). Clinical follow-up only was available in four patients, and autopsy reports were available in two(More)
A 20-MHz intravascular ultrasound (US) transducer inside a percutaneously inserted catheter was used to evaluate inferior vena caval (IVC) filters for thrombi in vitro and in vivo. Six different IVC filters were studied with intravascular US in a saline-filled model. Each filter had a characteristic, recognizable US pattern. Experimental thrombi as small as(More)
Epithelial ovarian cancer (OVAC) remains a highly lethal malignancy. It is a leading cause of cancer deaths among women in the United States causing more deaths than all other gynecologic malignancies combined. The pathogenesis of OVAC is not completely understood, but the process of repeated ovulation is believed to lead to genetic damage in the ovarian(More)
