RESUMEN
The goal of this study was to investigate the association between serum oestradiol levels and clinically significant erectile dysfunction in a cohort of men presenting for andrological evaluation. Retrospective review was conducted of patients that presented to a urologist with practice in andrology over an 18-month period. Patients completed the Male Sexual Health Questionnaire and had serum total testosterone and oestradiol measurements prior to 10:30 a.m. via immunoassay. t Tests, chi-square tests and multivariate logistic regression were used to compare clinical characteristics between those with adequate erectile function (erection scale score > 2) vs. clinically significant erectile dysfunction (erection scale score ≤ 2). Among 256 patients, average age was 49 years (SD 15), average serum oestradiol was 22.3 pg/ml (SD 10.6), and average serum total testosterone was 465.9 pg/ml (SD 206.3). On multivariate logistic regression, serum oestradiol was associated with clinically significant erectile dysfunction (OR 1.52 per SD increase, 95% CI 1.11-2.09, p = 0.009) when controlling for serum total testosterone, age, body mass index and smoking status. These results warrant future studies on the utility of measuring serum oestradiol in patients with erectile dysfunction and the use of aromatase inhibitors in patients with erectile dysfunction and elevated serum oestradiol.

In recent years, there has been increasing concern about youthful "binge" drinking and intoxication. Yet the meaning of intoxication remains under-theorized. This paper examines intoxication in a young adult nightlife scene, using data from a 2005-2008 National Institute on Drug Abuse-funded project on Asian American youth and nightlife. Analyzing in-depth qualitative interview data with 250 Asian American young adults in the San Francisco area, we examine their narratives about alcohol intoxication with respect to sociability, stress, and fun, and their navigation of the fine line between being "buzzed" and being "wasted." Finally, limitations of the study and directions for future research are noted.

PURPOSE: To assess the effects of buccal mucosal graft site non-closure versus closure on postoperative oral morbidity for male undergoing augmentation urethroplasty for urethral stricture. MATERIALS AND METHODS: We included randomized controlled trials. Inclusion criteria were male over the age of 18 with urethral stricture disease requiring reconstruction with buccal mucosal graft harvest. Primary outcomes of the review were postoperative oral pain, need for secondary oral procedures and cosmetic defects. RESULTS: We included 5 studies with 346 randomized patients with urethral strictures, of whom 260 completed the trials. In terms of primary outcomes, non-closure graft site may reduce oral pain on postoperative day #1 (standard mean difference [SMD] 0.24 lower; 95% confidence interval [CI] 0.61 lower to 0.12 higher; low certainty evidence [CoE]) but we are uncertain how this impacts pain on postoperative days 3 to 6 (SMD 0.35; 95% CI 0.12 to 0.81 higher; very low CoE). We are also very uncertain as to how it affects the need for secondary oral procedures (risk ratio [RR] 0.22; 95% CI 0.01 to 4.28; very low CoE). Non-closure may increase the risk of cosmetic defects (RR 2.40; 95% CI 0.93 to 6.22; low CoE). CONCLUSIONS: This review describes the trade-off for buccal mucosal graft site non-closure versus closure for various patient-important outcomes; decision-making will likely hinge on the relative value individual patients and surgeons place on them. The supporting evidence was rated as low and very low, thereby signaling substantial underlying uncertainty and the need for better trials.
RESUMEN
This article analyzes eating and beliefs about family meals in the qualitative interview narratives of 30 "at-risk" gang-involved young women in the San Francisco Bay Area. We begin our examination of consumption practices with a study of households and identify three major types-extended, single-parent and blended. Within these households, food purchasing and consumption activities are varied, and in many cases, our respondents rely upon extended family members and non-kin relations for support. In examining eating within the family, we identify two sets of practices and meanings: eating alone, and eating with others. Eating alone is symbolic of independence from one's family of origin, or is the result of familial conflict at the dinner table; however, it does not necessarily change our respondents' eating patterns. Eating with others in the family remains important, and many of the young women value family meals, although there are significant obstacles to eating regularly with the entire nuclear family. Many of these young women play an important role in the purchasing and preparation of food for family members as well. This paper highlights the importance of understanding family eating practices from the perspective of young people in the family, whose contribution to family ingestive practices has tended to be underestimated in much of available research literature.

Research on drug use among gay and bisexual men has primarily focused on examining the link between drug use- most notably, methamphetamine-sexual practices, and risk of HIV transmission. Drawing on in-depth qualitative data from 40 interviews with gay and bisexual Asian American men, we examine perceptions and meanings associated with cocaine use in the San Francisco Bay Area gay community. We found that the participants, in contrast to their negative perceptions of methamphetamine use, believed that cocaine enhanced sociability and was acceptable for use in most social situations. Furthermore, participants perceived little connection between cocaine use and risky sexual practices, emphasizing the drug's safety relative to other illicit substances. Based on these findings, we suggest that an increase in the favorability of cocaine use might be an unintended consequence of methamphetamine prevention campaigns targeting the gay community, with their emphasis on the harmful effects of drug use, unsafe sex, and HIV risk.

OBJECTIVE: To assess the perceived importance of male ejaculatory function (EjF) from the perspective of adult men and their sexual partners. METHODS: In a large survey study, men were asked about the importance of their own EjF. Sexual partners of men were asked about the general importance their partner's EjF, and whether they would support a partner's decision to pursue BPH treatment despite ejaculatory dysfunction. RESULTS: One hundred and two men completed the survey section regarding their own EjF, and 100 participants completed the survey section assessing the importance of their male partner's EjF. While 55% of men agreed or strongly agreed that "ejaculation is an important part of an enjoyable sexual experience," only 30% of partners similarly agreed or strongly agreed (P = .005). A greater percentage of men (12%) agreed or strongly agreed that they "preferred large semen volume" compared to sexual partners of men (3%), however this was not significant. Sixty eight percent of sexual partners would agree or strongly agree to support their male partner's decision to pursue BPH treatment despite potential ejaculatory dysfunction. CONCLUSION: The perceived importance of EjF differs between men and their sexual partners, as men believe ejaculation to be a more important component of an enjoyable sexual experience than their partners.

Background: Published case reports on the management of ureteral stones in patients with prior ureterosigmoidostomy have described the challenges of direct retrograde access to the ureter using standard endourologic instruments. In light of these challenges, reported effective techniques have involved either (1) direct retrograde access utilizing sigmoid endoscopy with air insufflation or (2) percutaneous antegrade access. We report the first experience of effective retrograde ureteroscopy utilizing traditional endourologic instruments in a patient without percutaneous access. Case Presentation: The patient is a 70-year-old man born with bladder exstrophy who underwent end colostomy and ureterosigmoidostomy as a child. He presented with a symptomatic 6 mm stone at the right ureterosigmoid junction. A trial of spontaneous passage failed because of persistent pain. Treatment options were limited by the patient's recent history of coronary stent placement, requiring uninterrupted antiplatelet therapy with clopidogrel. As such, we attempted retrograde ureteroscopy through a transrectal approach. Anticipating some difficulty in the identification of the ureteral orifices, we administered methylene blue at the time of induction. After placing the patient in lithotomy position, we advanced a flexible cystoscope to the rectosigmoid junction where we identified a ureteral orifice. Guidewire access was obtained and we confirmed right-sided laterality with fluoroscopic imaging. A semirigid ureteroscope was passed to the ureterosigmoid junction where the stone was encountered and retrieved intact using a basket. A 6 × 26 Double-J stent was placed with a string to facilitate removal 5 days later. The postoperative course was unremarkable. Conclusion: Despite the previously reported challenges of the approach, retrograde ureteroscopy without percutaneous access represents a viable treatment option for ureteral stones in patients with ureterosigmoidostomy.
RESUMEN
OBJECTIVE: To examine urine and stone bacteriology of struvite stone formers in a large cohort of patients undergoing percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: A total of 1191 patients, with stone and urine cultures, treated with PCNL for renal calculi were included in the study. Statistical differences were assessed using Mann-Whitney U and T-tests. RESULTS: Stone cultures were positive in 72% of patients with struvite stones. Urea-splitting organisms accounted for only half of the positive stone cultures. Enterococcus (9/50, 18%), Proteus (9/50, 18%), and Escherichia coli (6/50, 12%) were the most commonly identified organisms. Notably, two-thirds of struvite formers with negative stone culture had at least one positive culture for a urea-splitting organism on urine culture going back 1 year from the time of surgery. A majority (67%) of struvite stone cultures were found to be resistant to first- and second-generation cephalosporins. CONCLUSIONS: The bacteriology of struvite stones has shifted away from traditional urea-splitting organisms and antibiotic coverage must be expanded to include organisms such as Enterococcus that do not respond to cephalosporins. Causative organisms may be found by going back in time to identify the initial organism that could have induced struvite stone formation to inform preventative therapy.

OBJECTIVES: To identify clinical predictors of testosterone deficiency (TD) in men with erectile dysfunction (ED), thereby identifying subgroups that are most likely to benefit from targeted testosterone screening. METHODS: Retrospective review was conducted on 498 men evaluated for ED between January 2013 and July 2014. Testing for TD by early morning serum measurement was offered to all eligible men. Patients with history of prostate cancer or testosterone replacement were excluded. Univariable linear regression was conducted to analyze 19 clinical variables for associations with serum total testosterone (TT), calculated free testosterone (cFT), and TD (T <300 ng/dL or cFT <6.5 ng/dL). Variables significant on univariable analysis were included in multiple regression models. RESULTS: A total of 225 men met inclusion criteria. Lower TT levels were associated with greater body mass index (BMI), less frequent sexual activity, and absence of clinical depression on multiple regression analysis. TT decreased by 49.5 ng/dL for each 5-point increase in BMI. BMI and age were the only independent predictors of cFT levels on multivariable analysis. Overall, 62 subjects (27.6%) met criteria for TD. Older age, greater BMI, and less frequent sexual activity were the only independent predictors of TD on multiple regression. We observed a 2.2-fold increase in the odds of TD for every 5-point increase in BMI, and a 1.8-fold increase for every 10 year increase in age. CONCLUSIONS: Men with ED and elevated BMI, advanced age, or infrequent sexual activity appear to be at high risk of TD, and such patients represent excellent potential candidates for targeted testosterone screening.

Qualitative research is often conceptualized as inherently small-scale research, primarily conducted by a lone researcher enmeshed in extensive and long-term fieldwork or involving in-depth interviews with a small sample of 20 to 30 participants. In the study of illicit drugs, traditionally this has often been in the form of ethnographies of drug-using subcultures. Such small-scale projects have produced important interpretive scholarship that focuses on the culture and meaning of drug use in situated, embodied contexts. Larger-scale projects are often assumed to be solely the domain of quantitative researchers, using formalistic survey methods and descriptive or explanatory models.In this paper, however, we will discuss qualitative research done on a comparatively larger scale-with in-depth qualitative interviews with hundreds of young drug users. Although this work incorporates some quantitative elements into the design, data collection, and analysis, the qualitative dimension and approach has nevertheless remained central. Larger-scale qualitative research shares some of the challenges and promises of smaller-scale qualitative work including understanding drug consumption from an emic perspective, locating hard-to-reach populations, developing rapport with respondents, generating thick descriptions and a rich analysis, and examining the wider socio-cultural context as a central feature. However, there are additional challenges specific to the scale of qualitative research, which include data management, data overload and problems of handling large-scale data sets, time constraints in coding and analyzing data, and personnel issues including training, organizing and mentoring large research teams. Yet large samples can prove to be essential for enabling researchers to conduct comparative research, whether that be cross-national research within a wider European perspective undertaken by different teams or cross-cultural research looking at internal divisions and differences within diverse communities and cultures.
