PURPOSE Hormonal therapy (HT) is the current mainstay of systemic treatment for prostate specific antigen (PSA) only recurrence (PSAR), however, there is virtually no published literature comparing HT to observation in the clinical setting. The goal of this study was to examine the Department of Defense Center for Prostate Disease Research observational(More)
A purification procedure for L-myo-inositol-1-phosphate synthase (EC from yeast is described. The method routinely produces enrichments of 500-fold with 20-40% yields. In addition, a procedure for obtaining highly specific and purified antibody against the protein is described. The molecular weight of the native enzyme as determined by gel(More)
PURPOSE Parastomal hernia is a frequent complication of stoma formation after radical cystectomy. We determined the prevalence and risk factors for the development of parastomal hernia after radical cystectomy. MATERIALS AND METHODS We conducted a retrospective study of 433 consecutive patients who underwent open radical cystectomy and ileal conduit(More)
BACKGROUND Selective embolization in pregnancy for treatment of renal hemorrhage has been reported infrequently in the literature; the possibility of minimizing radiation dose to the fetus by using dose-sparing fluoroscopy techniques is not commonly appreciated by the obstetric community. CASE We describe performing partial renal embolization with the use(More)
PURPOSE In the last decade numerous groups have shown that low levels of pretreatment serum total testosterone consistently predict more aggressive disease, worse prognosis and worse treatment response in patients with metastatic prostate cancer. Prior studies have not demonstrated this same correlation in patients with known localized disease. We(More)
PURPOSE To determine if obesity is associated with higher prostate specific antigen recurrence rates after radical prostatectomy (RP), and to explore racial differences in body mass index (BMI) as a potential explanation for the disparity in outcome between black and white men. PATIENTS AND METHODS A retrospective, multi-institutional pooled analysis of(More)
PURPOSE Surgical organizations have begun to focus their efforts on providing humanitarian assistance in international communities. Most surgeons do not have previous international experience and lack an understanding of what is expected and what care they can provide. The unknown factors include case types, patient volume, postoperative care, and(More)
BACKGROUND Because of public awareness and screening, the incidence of clinically localized prostate cancer has increased dramatically in the last 15 years. The Department of Defense Center for Prostate Disease Research (CPDR) was established by the US Congress in 1991 to study prostate cancer in the US military health care system. A key component of CPDR(More)
OBJECTIVE The purpose of this article is to investigate the added value of second-opinion evaluation of prostate MRI by subspecialized genitourinary oncologic radiologists for the assessment of extracapsular extension (ECE) of prostate cancer. MATERIALS AND METHODS We performed a retrospective evaluation of initial and second-opinion radiology reports of(More)
BACKGROUND On January 12, 2010, Haiti experienced the western hemisphere's worst-ever natural disaster. Within 24 hours, the United States Naval Ship Comfort received orders to respond, and a group of more than 500 physicians, nurses, and staff undertook the largest and most rapid triage and treatment since the inception of hospital ships. METHODS These(More)
