BACKGROUND ImmunoCyt (uCyt) and UroVysion are ancillary studies that may aid in the detection of urothelial carcinoma in urine specimens. We compared ImmunoCyt and UroVysion to urine cytology in the ability to detect recurrent urothelial carcinoma. METHODS Single voided urine samples were obtained from 100 patients who had a previous history of bladder(More)
Infants or children who had congenital or neonatal infection with cytomegalovirus (CMV) or herpes simplex virus (HSV) have fewer than 1:30,000 mononuclear cells in their blood lymphocytes preparations that proliferate in cultures stimulated with the corresponding viral antigens. CMV and HSV responder cell frequencies in children and adults whose immunity(More)
BACKGROUND Thyroid fine-needle aspiration (FNA) plays a pivotal role in the evaluation of thyroid nodules. Up to 30% of cases are diagnosed as indeterminate by FNA, including atypia of undetermined significance, follicular lesion of undetermined significance, suspicious for a follicular neoplasm, and follicular neoplasm, with approximately two-thirds having(More)
Epstein-Barr virus-transformed human B cells expressed cell surface varicella-zoster virus (VZV) antigens after superinfection with VZV although they did not form infectious centers in a plaque assay. The VZV-superinfected cells were lysed by autologous VZV-stimulated T-cell lines and their derivative clones. The effector cells were specific for VZV and an(More)
The frequency of varicella-zoster virus (VZV)-specific T lymphocytes was higher in elderly subjects who had herpes zoster infections than in age-matched controls. This increase in T cell response persisted for at least 2 years while antibody levels to VZV returned to control values at this time. There were no differences in T cell or antibody responses to(More)
Urine cytology coupled with cystoscopic examination has been and remains the standard in the initial evaluation of lower urinary tract lesions to rule out bladder cancer. However, cystoscopy is invasive and may miss some flat lesions, whereas cytology has low sensitivity in low-grade papillary disease. Additional lab-based or office-based markers are needed(More)
BACKGROUND The value of gene expression classifier (GEC) testing for cytologically indeterminate thyroid nodules lies in its negative predictive value, which is influenced by the prevalence of malignancy. We incorporated actual GEC test performance data from a tertiary referral center into a cost-effectiveness analysis of GEC testing. METHODS We evaluated(More)
Cytotoxic, proliferative, and serum IgG antibody responses to varicella-zoster virus (VZV) were measured monthly in 29 young adults for 3 months following primary immunization with the Oka strain attenuated VZV vaccine. No subjects had lymphocytes stimulated to VZV-specific cytotoxicity at study entry although lymphocytes from 2 subjects proliferated when(More)
Blood mononuclear cells (MNC) were stimulated with VZV in the form of live cell-associated virus, glutaraldehyde-fixed VZV-infected fibroblasts or an extracted VZV antigen. After 7 days of culture with live virus, IL2 receptors (IL2R) were found on CD4 and CD8 cells while cultures stimulated with fixed or extracted antigen had IL2R only on CD4 cells. Clones(More)
Ovulation induction using a low dose of human menopausal gonadotrophins and clomiphene citrate for in vitro fertilisation and embryo transfer is described. Sixty-two cycles of ovulation induction were initiated in 37 patients. Forty-six laparoscopies were performed, yielding 116 oocytes. Of these, 90 (77.6%) cleaving embryos developed, and in 36 transfers(More)
