While surgery has been the standard treatment for patients with severe primary mitral regurgitation (PMR), the role of surgery for severe secondary mitral regurgitation (SMR) remained debated. We therefore investigated the prognostic differences of surgery for patients with either severe PMR or SMR. ⋯ Mitral valve surgery for patients with heart failure and severe MR was associated with better survival in patients with PMR, but not in those with SMR.

The ability to manage the myriad of musculoskeletal conditions successfully requires multiple years of training. Access to and completion of orthopaedic surgical training entails an often grueling, highly regulated path to certification to practice. ⋯ This report from eight nations on five continents details the distinctive features of that training, including the number of positions available, the examinations required, the gender distribution of residents, and available possibilities once the residence period is complete. This analysis shows a wide variation in the orthopaedic trauma training program worldwide, with emphasis on different skills per country.

Obesity is a growing epidemic in the United States. While many adverse effects of obesity on surgical outcome are well studied, a direct correlation among obesity, pseudarthrosis, and adjacent segment pathology is not well defined. In this study we aimed to identify the effect of body mass index (BMI) on pseudarthrosis, adjacent segment pathology (ASP), and reoperation after short-segment (1-3 levels) open posterior lumbar fusion (PLF). ⋯ Obese patients undergoing short-segment open PLF have comparable results in terms of pseudarthrosis, ASP, and reoperation.

Juvenile nasopharyngeal angiofibroma (JNA) is a very rare hemorrhagic vascular tumor that predominantly affects adolescent boys. The tumor is relatively large when detected, and the risk of intraoperative bleeding is high. We aimed to examine factors associated with intraoperative blood loss in JNA surgery. ⋯ The amount of bleeding significantly correlated with the number of remaining nutrient vessels from the ICA after preoperative embolization and with the total Cmax/region of interest. The ability to predict the amount of preoperative blood loss using this study will facilitate proposals for external incisions in patients with JNA.
