conclusions nbi cystoscopy improved the detection rate. although false positives were more common with nbi, this was not statistically significant. nbi found additional aggressive tumors, which underscores the impact of detection in eortc recurrence risk scoring. results fifty patients, aged 63.86 ± 10.05 years, were enrolled. the overall detection rate was 98.9% for nbi vs. 89.4% for wli (p = ...

We studied erythropoiesis in 31 patients with vitamin B12 deficiency by measuring serum erythropoietin (s-Epo), serum transferrin receptor (s-TfR, taken as an index of total erythroid activity), reticulocyte count, and the reticulocyte maturation index (RMI). s-Epo and s-TfR were measured with commercial immunoassays, whereas reticulocyte count and RMI were determined by flow cytometry. s-Epo (...

BACKGROUND Pedobarography offers dynamic information about the foot, but the interpretation of its large data is challenging. In a prior study it was shown that attention can be restricted to pedobarographic midfoot load data. We aim to verify this observation in ankle osteoarthritic and contralateral feet. METHODS We assessed both feet of 120 patients with end-stage ankle osteoarthritis (OA)...

OBJECTIVES Detect presence of sleep-related breathing disorders (SRBD) in epochs of 1 min by signal analysis of Holter ECG recordings. METHODS In 121 patients, 140 synchronized polysomnograms (PSGs) an...

BACKGROUND Of the approximately 2.4 million American women with a history of breast cancer, 43% are aged ≥ 65 years and are at risk for developing subsequent malignancies. METHODS Women from 6 geographically diverse sites included 5-year breast cancer survivors (N = 1361) who were diagnosed between 1990 and 1994 at age ≥ 65 years with stage I or II disease and a comparison group of women with...
