UNLABELLED Approximately 12% of the U.S. population is Hispanic, with the majority residing in urban centers such as Los Angeles. The prevalence of BRCA mutations among high-risk Hispanic families is unknown. METHODS One hundred and ten unrelated probands of Hispanic origin, with a personal or family history of breast and/or ovarian cancer, presented for(More)
PURPOSE While it remains controversial whether LRP or da Vinci RAP offers any advantages over radical retropubic prostatectomy, LRP and RAP are being used more frequently. We reviewed our experience with these minimally invasive techniques. MATERIALS AND METHODS We reviewed intraoperative and early postoperative complications of 358 LRPs performed from(More)
A population based case-control study was conducted to determine whether risk of non-Hodgkin's lymphoma (NHL) in the absence of HIV infection is related to the previous use of tobacco, alcohol or recreational drugs. A total of 378 residents of Los Angeles County who were diagnosed with high- or intermediate-grade NHL were compared with individually age-,(More)
PURPOSE We report on outcomes of robotic assisted laparoscopic radical prostatectomy as salvage local therapy for radiation resistant prostate cancer. MATERIALS AND METHODS We retrospectively reviewed the charts of all patients who underwent robotic assisted laparoscopic radical prostatectomy for biopsy proven prostate cancer after primary radiation(More)
The effects of cigarette smoking result from the delivery of nicotine, other components of smoke, and sensory stimulation. In the present study, pharmacological effects of new tobacco-derived de-nicotinized cigarettes (controls) were compared with standard cigarettes. The de-nicotinized cigarettes had the appearance, draw and taste of standard cigarettes(More)
PURPOSE The incidence rates of non-Hodgkin's lymphoma (NHL) unrelated to human immunodeficiency virus infection are lower for women than for men; yet, few factors have been identified that may account for this difference in risk. NHL is difficult to study epidemiologically because this disorder represents a group of malignancies that differ in terms of(More)
Decreased mechanical use of the skeleton results in osteoporosis in all species that have been studied, including humans. The unique metabolic adaptations of denning bears, however, suggest that these animals have evolved osteoregulatory mechanisms to protect against osteoporosis. The authors studied calcium and bone metabolism in black bears during three(More)
BACKGROUND We report our technique for robotic-assisted laparoscopic radical cystoprostatectomy (RARCP) and extracorporeal urinary diversion and present their clinical outcomes. METHODS Between October 2003 and December 2008 we performed 58 RARCPs with extracorporeal continent urinary diversion. Preoperative, operative and postoperative data was(More)
In industrialized countries, over-the-counter dietary supplements have become popular in preventing and treating an expanding list of medical conditions.
