The Thermal Emission Spectrometer (TES) investigation on Mars Global Surveyor (MGS) is aimed at determining (1) the composition of surface minerals, rocks, and ices; (2) the temperature and dynamics of the atmosphere; (3) the properties of the atmospheric aerosols and clouds; (4) the nature of the polar regions; and (5) the thermophysical properties of the(More)
BACKGROUND We seek to determine if testosterone levels below the accepted castration threshold (50 ng/dL) have an impact on time to progression to castrate-resistant prostate cancer (CRPC). METHODS This is a prospective cohort series of patients undergoing androgen deprivation therapy (ADT) with luteinizing hormone-releasing hormone agonist or antagonist(More)
AIM To review the literature on the use of prophylactic balloon occlusion alone and in conjunction with arterial embolization of the internal iliac arteries in women with placenta accreta. MATERIALS AND METHODS The PubMed, MEDLINE, CINAHL, EMBASE, and Cochrane Library databases were searched for keywords related to this technique and its use in the(More)
INTRODUCTION Penile fractures have classically been thought to require immediate surgical intervention; however, recent series have described acceptable outcomes with delayed repair. In this systematic review, we compared complication rates between immediate and delayed repair of penile fractures. METHODS A systematic search of MEDLINE, Embase, CENTRAL,(More)
To determine whether the method of bladder cuff excision (BCE) during laparoscopic radical nephroureterectomy for upper urinary tract urothelial carcinoma is associated with rates of disease recurrence or metastases. We performed a retrospective review of all laparoscopic radical nephroureterectomies performed at our institution over 10 years. Three methods(More)
INTRODUCTION : The utility of prostate cancer screening is controversial. We sought to determine whether Ontario's family physicians believe it is beneficial and to characterize their screening protocols. METHODS : A survey was developed with input from urologists, family physicians and the Ontario Medical Association's Section on General and Family(More)
INTRODUCTION Intermittent androgen deprivation therapy (IADT) for prostate cancer involves cycles of androgen deprivation therapy (ADT) with a period between cycles where testosterone is allowed to rise above castrate levels. A number of recent randomized controlled trials (RCTs) have compared survival and health-related quality-of-life (HRQOL) between IADT(More)
Down syndrome (DS), caused by an extra copy of chromosome 21, affects 1 in 750 live births and is characterized by cognitive impairment and a constellation of congenital defects. Currently, little is known about the molecular pathogenesis and no direct genotype-phenotype relationship has yet been confirmed. Since DS amniocytes are expected to have a(More)
This review discusses the most commonly employed techniques in the repair of proximal hypospadias, highlighting the advantages and disadvantages of single versus staged surgical techniques. Hypospadias can have a spectrum of severity with a urethral meatus ranging from the perineum to the glans. Associated abnormalities are commonly found with proximal(More)
