Selling blood and gametes during tough economic times: insights from Google search.

INTRODUCTION: To use Google Insights search volume and publicly available economic indicators to test the hypothesis that sperm, egg, and blood donations increase during economic downturns and to demonstrate the feasibility of using Google search volume data to predict national trends in actual sperm, egg, and blood donations rates. MATERIALS AND METHODS: Cross-correlation statistical analysis comparing Google search data for terms relating to blood, egg, and sperm donations with various economic indicators including the S&P 500 closing values, gross domestic product (GDP), the U.S. Index of Leading Indicators (U.S. Leading Index), gross savings rate, mortgage interest rates, unemployment rate, and consumer price index (CPI) from 2004-2011. A secondary analysis determined the Pearson correlation coefficient between Google search data with actual sperm, egg, and blood donation volume in the U.S. as measured by California Cryobank, the National Assisted Reproductive Technology Surveillance System, and the National Blood Collection and Utilization Survey, respectively. Significance of cross-correlation and Pearson correlation analysis as indicated by p value. RESULTS: There were several highly significant cross-correlation relationships between search volume and various economic indicators. Correlation between Google search volume for the term 'sperm donation,' 'egg donation,' and 'blood donation' with actual number of sperm, egg and blood donations in the United States demonstrated Pearson correlation coefficients of 0.2 (p > 0.10), -0.1 (p > 0.10), and 0.07 (p > 0.10), respectively. Temporal analysis showed an improved correlation coefficient of 0.9 (p < 0.05) for blood donation when shifted 12 months later relative to Google search volume. CONCLUSION: Google search volume data for search terms relating to sperm, egg, and blood donation increase during economic downturns. This finding suggests gamete and bodily fluid donations are influenced by market forces like other commodities. Google search may be useful for predicting blood donation trends but is more limited in predicting actual semen and oocyte donation patterns.

Robot-assisted laparoscopic hysterectomy, gonadal biopsy, and orchiopexies in an infant with persistent mullerian duct syndrome.

An infant born with hypospadias and no palpable gonads was diagnosed with persistent mullerian duct syndrome (PMDS) based on history, physical examination, laboratory testing, and radiologic imaging. A robot-assisted laparoscopic hysterectomy, right gonadal biopsy, and bilateral orchiopexies were performed without incident. Final pathology confirmed the diagnosis of PMDS. To our knowledge, this is only the second report of PMDS managed through a robot-assisted laparoscopic approach.

The accordion antiretropulsive device improves stone-free rates during ureteroscopic laser lithotripsy.

PURPOSE: The Accordion is a novel endoscopic device that prevents retropulsion of ureteral stones and their fragments during ureteroscopic laser lithotripsy. We describe our experience with its use focusing on three main endpoints: operating time, fluoroscopy time, and stone-free rates. METHODS: Of 308 consecutive cases of unilateral ureteroscopic laser lithotripsy from 2006-2010, we analyzed 235 cases of ureteral stones. Chart review was performed to document patient demographics (age, sex, and race), stone characteristics (stone size, density, laterality, location, and multiplicity), operative characteristics (use of preoperative and/or postoperative stents, ureteral balloon dilators, ureteral access sheaths, the Holmium laser, and the Accordion device), and surgical outcomes (operative time, fluoroscopy time, stone-free status, and complications). RESULTS: The baseline characteristics between the Accordion and non-Accordion group were statistically similar. In univariate nonparametric tests of medians, Accordion device usage was not associated with a significant reduction in fluoroscopy time (median 1.68 vs. 1.95 minutes, p=0.28) or operating time (median 52.5 vs. 61 minutes, p=0.19). However, the stone-free rate for the Accordion group was significantly higher compared to the non-Accordion group (84.2% vs. 53.6%, p=0.001). In multivariate generalized linear models, Accordion usage was not associated with decreased operating or fluoroscopy times. Accordion use was associated with statistically significant greater odds of stone-free status (odds ratio 4.35, 95% confidence interval 2.36-8.00). Complication severity and rates were comparable between the two groups. CONCLUSIONS: The Accordion antiretropulsive device improves stone-free rates during ureteroscopic laser lithotripsy. Prospective studies are needed to validate these results.

Labioplasty for hypertrophic labia minora contributing to recurrent urinary tract infections.

INTRODUCTION: Reduction labioplasty for hypertrophic labia minora is often performed for aesthetic reasons by cosmetic vaginal surgeons. However, hypertrophy of the labia minora can also result in significant morbidity because it causes physical discomfort during activity and interferes with the ability to maintain local hygiene and perform intermittent self-catheterization in certain patients. OBJECTIVES: We describe a case in which a commonly used technique for reduction labioplasty was performed on a patient who had difficulty performing intermittent catheterization and report on the aesthetic and functional outcomes. METHODS: A linear resection labioplasty was performed in a 13-year-old girl who was having increasing difficulty performing intermittent self-catheterization because of redundant labial tissue. She was also developing frequent recurrent urinary tract infections thought to be secondary to difficulty maintaining local hygiene and reduced compliance with her intermittent catheterization regimen. RESULTS: An excellent cosmetic and functional result was achieved with the procedure. Comparison of preoperative and postoperative photographs demonstrates the extent of the reduction labioplasty. The patient has not had any more difficulty with catheterization or recurrent urinary tract infections in 30 months of follow-up. CONCLUSIONS: Reduction labioplasty is indicated for hypertrophic labia minora for more than aesthetic reasons. We describe a case in which the procedure allowed the patient to more easily perform intermittent catheterization and helped eliminate her recurrent urinary tract infections.
