Editorial Commentary: Simulation-Based Training in Orthopaedic Surgery: Current Evidence and Limitations.

Simulation-based training has been widely adopted by surgical educators and is now an essential component of the modern resident's skills acquisition pathway and career progression. The challenges faced by residents because of lack of exposure as a result of working-time directives-and now the COVID-19 (coronavirus disease 2019) pandemic limiting nonurgent and elective operating-reinforce the need for evidence-based simulation training. Although a wide range of training platforms have been developed, very few have shown transfer of skills. Simulation is thought to enhance the initial phase of the procedural learning curve; however, this hypothesis is yet to be tested in a high-quality study. Nevertheless, in light of the current evidence, simulation-based procedural curricula should be developed using the strengths of multiple different training platforms while incorporating the essential concept of nontechnical skills.

Vasospastic myocardial infarction caused by a slimming agent-do not forget non-prescription drugs.

A 41-year-old woman presented with central chest discomfort. She had been previously well, was an ex-smoker and reported no regular medication. The ECG developed T-wave changes inferiorly and anterolaterally and troponin I concentrations were elevated confirming non-ST elevation myocardial infarction. Cardiac catheterization showed severe spasm of the right and left anterior descending coronary arteries which resolved with intracoronary nitrates. She later volunteered that prior to presentation she had been taking non-prescription Acti-Phen a slimming agent containing phentermine. Acti-Phen had its licence withdrawn in 2001 because of cardiovascular side effects including coronary spasm. Accordingly, she was advised to avoid Acti-Phen in future. The case emphasizes the importance of obtaining a complete drug history, including non-prescription drugs, in patients presenting with acute coronary syndromes.

The effectiveness of Google GLASS as a vital signs monitor in surgery: A simulation study.

INTRODUCTION: To assess the effectiveness of the Google GLASS as a vital signs monitor in a surgical setting and identify potential uses. METHODS: This prospective, observational and comparative study recruited novice (n = 24), intermediate (n = 8) and expert urologists (n = 5). All candidates performed a procedure on the GreenLight Simulator within a simulated setting using a standard vital signs monitor and then the Google GLASS. The time taken to respond to abnormal vital signs during both sessions was recorded. A quantitative survey was used to assess the usability and acceptability of the Google GLASS surgery. RESULTS: The majority (84%) of participants responded quicker to abnormal signs with the Google GLASS compared to a standard monitor (p = 0.0267). The average simulation score during a standard-monitor and GLASS-session scored to be statistically insignificant (p = 0.253). All parameters of simulation were also similar in both sessions including average sweep speed (p = 0.594), average blood loss (p = 0.761) and average grams vaporised (p = 0.102). DISCUSSION: Surgical performance between both sessions was similar and not hampered by the use of Google GLASS. Furthermore, 81% of candidates stated the GLASS was comfortable to wear during the procedure. CONCLUSION: This study has demonstrated that head-mounted displays such as the Google GLASS are potentially useful in surgery to aid patient care without hampering the surgeons view. It is hoped that the innovation and evolution of these devices triggers the potential future application of such devices within the medical field.
