BACKGROUND: Many urologic surgeons refer to biopsy core details for decision making in cases of localized prostate cancer (PCa) to determine whether an extended resection and/or lymph node dissection should be performed. Furthermore, recent reports emphasize the predictive value of prostate-specific antigen density (PSAD) for further risk stratification, not only for low-risk PCa, but also for intermediate- and high-risk PCa. This study focused on these parameters and compared respective predictive impact on oncologic outcomes in Japanese PCa patients...

Catharanthus roseus (C. roseus) and Vinca minor (V. minor) are two common important medical plants belonging to the family Apocynaceae. In this study, we used non-targeted GC-MS and targeted LC-MS metabolomics to dissect the metabolic profile of two plants with comparable phenotypic and metabolic differences. A total of 58 significantly different metabolites were present in different quantities according to PCA and PLS-DA score plots of the GC-MS analysis. The 58 identified compounds comprised 16 sugars, eight amino acids, nine alcohols and 18 organic acids...

OBJECTIVE: To assess the relationship between robotic surgical simulation performance and the real-life surgical skill of attending surgeons. We hypothesized that simulation performance would not correlate with real-life robotic surgical skill in attending surgeons. DESIGN: In 2013, Birkmeyer et al. demonstrated an association between laparoscopic surgical performance as determined by expert review of video clips and surgical outcomes. Using that model of expert review, we studied the relationship between robotic simulator performance and real-life surgical skill...

Tonsillectomy is one of the most common surgical procedures performed worldwide. Several techniques have been developed to reduce morbidity and enhance recovery after tonsillectomy. Our study was designed to compare post-operative pain with three different techniques: cold dissection (CD), monopolar-bipolar dissection (MBD) and coblation dissection (CBD). 103 adults were scheduled for elective tonsillectomy from September 2014 to December 2015, and were randomized to CD, MBD and CBD. Post-operative pain was assessed using visual analogue scale (VAS) and Lattinen Test (LT)...
