Cataract surgery with phacoemulsification is a challenging procedure for surgeons in training to learn to perform safely, efficiently, and effectively. We review the auxiliary learning tools outside the operating room that residency programs have incorporated into their curriculum to improve surgical skills, including wet lab and surgical simulators. We then discuss different methods of teaching cataract surgery in the operating room. Our goal is to define a learning curve for cataract surgery. We demonstrate that complication rates decline significantly after a resident performs an average of 70 cases...

BACKGROUND: Tension band wiring (TBW) and locked plating are common treatment options for Mayo IIA olecranon fractures. Clinical trials have shown excellent functional outcomes with both techniques. Although TBW implants are significantly less expensive than a locked olecranon plate, TBW often requires an additional operation for implant removal. To choose the most cost-effective treatment strategy, surgeons must understand how implant costs and return to the operating room influence the most cost-effective strategy...

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...

REVIEW
Minhao Hu, David Wattchow, Dayan de Fontgalland
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...
