BACKGROUND: Surgical access to the temporal horn is necessary to treat tumors and vascular lesions, but is used mainly in patients with mediobasal temporal epilepsy. The surgical approaches to this cavity fall into 3 primary categories: lateral, inferior, and transsylvian. The current neurosurgical literature has underestimated the interruption of involved fiber bundles and the correlated clinical manifestations. OBJECTIVE: To delineate the interruption of fiber bundles during the different approaches to the temporal horn...

Effective teamwork and communication can decrease medical errors in environments where the culture of safety is enhanced. Health care can benefit from programs that are based on teamwork, as in other high-stress industries (e.g., aviation), with crew resource management programs, simulator use, and utilization of checklists. Medical team training (MTT) with a strong leadership commitment was used at our institution to focus specifically on creating open, yet structured, communication in operating rooms. Training included the 3 phases of the World Health Organization protocol to organize communication and briefings: preoperative verification, preincision briefing, and debriefing at or near the end of the surgical case...

Due to their numerous advantages, laparoscopic surgical procedures are increasingly becoming common in the operation theatres over the past few decades. Virtual reality training simulators have played a significant role during this transition from traditional to laparoscopic procedures by enhancing surgical skills, such as hand-eye coordination in laparoscopy, and practising surgical scenarios that cannot be easily created using physical models. This paper presents a general framework for such a training simulator while identifying its key components and their specific roles in enhancing various laparoscopic skills...

The landscape of surgical anatomy education is progressively changing. Traditional methods, such as cadaveric dissection and didacticism are being increasingly phased out in undergraduate courses for multimodal approaches incorporating problem-based learning, radiology and computer-based simulations. Although effective at clinically contextualizing and integrating anatomical information, these approaches may be a poor substitute for fostering a grasp of foundational 'pure' anatomy. Dissection is ideal for this purpose and hence remains the cornerstone of anatomical education...

Despite advanced efforts in early diagnosis, aggressive surgical treatment, and use of targeted chemotherapies, the prognosis for many cancers is still dismal. This emphasizes the necessity to develop new strategies for understanding tumor growth and metastasis. Here we use a systems approach that combines mathematical modeling and numerical simulation to develop a predictive computational model for prostate cancer and its subversion of the bone microenvironment. This model simulates metastatic prostate cancer evolution, progressing from normal bone and hormone levels to quantifiable diseased states...

BACKGROUND AND OBJECTIVES: A prior meta-analysis showed favorable metabolic effects of structured triglyceride (STG) lipid emulsions in surgical and critically ill patients compared with mixed medium-chain/long-chain triglycerides (MCT/LCT) emulsions. Limited data on clinical outcomes precluded pharmacoeconomic analysis. We performed an updated meta-analysis and developed a cost model to compare overall costs for STGs vs MCT/LCTs in Chinese hospitals. METHODS AND STUDY DESIGN: We searched Medline, Embase, Wanfang Data, the China Hospital Knowledge Database, and Google Scholar for clinical trials comparing STGs to mixed MCT/LCTs in surgical or critically ill adults published between October 10, 2013 and September 19, 2015...

There are massive hidden costs in the current paradigm of surgical training related to increased operative times for procedures with resident involvement and costs of medical errors. Shifting procedural training outside of the operating room through use of simulation has the potential to improve patient safety, minimize learning time to achieve competency, and increase operative efficiency. Investment in surgical simulation has the potential to reduce costs to health care systems through improved operating room efficiency and reduction of medical errors...

Simulating natural characteristics and aesthetics in reconstructed ears has provided a complex 3-dimensional puzzle for those treating patients with microtia. Costochondral grafts remain the gold standard for autologous reconstruction. However, other options such as Medpor and prosthetics are indicated depending on patient circumstances and personal choice. Research into tissue engineering offers an alternative method to a traditional surgical approach that may reduce donor-site morbidity. However, tissue engineering for microtia reconstruction brings new challenges such as cell sourcing, promotion of chondrogenesis, scaffold vascularization, and prevention of scaffold contraction...

In the U.S. health care sector, the economic logic of specialization as an organizing principle has come under active debate in recent years. An understudied case is that of ambulatory surgery centers (ASCs), which recently have become the dominant provider of specific surgical procedures. While the majority of ASCs focus on a single specialty, a growing number are diversifying to offer a wide range of surgical services. We take a multiple output cost function approach to an empirical investigation that compares production economies in single specialty ASCs with those in multispecialty ASCs...
