Introduction. Teaching surgical skills has historically been a hands-on activity, with instructors and learners in close physical proximity. This paradigm was disrupted by the COVID-19 pandemic, requiring innovative solutions to surmount the challenges of teaching surgical skills remotely. In this work, we describe our institution’s path and early results of developing an interactive remote surgical skills course for medical students in the surgical clerkship. Methods. 31 third-year medical students were distributed a set of surgical equipment and 3D printed phone dock. Each participant completed a baseline questionnaire and underwent 3 structured interactive remote sessions on surgical instruments, knot tying, and suturing techniques. Students were instructed on sharing their first-person viewpoint and received real-time feedback on their knot tying and suturing techniques from the course instructor. Pre- and post-session surveys were conducted and analyzed. Results. All students were able to complete the remote surgical skills course successfully, as defined by visually demonstrating successful two-handed knot and simple suture techniques. Students’ aggregate confidence score in their knot tying ability (pretest mean 7.9, SD 0.7 vs posttest mean 9.7, SD 0.9, t-statistic −2.3, P = .03) and suturing ability (pretest mean 8.0, SD 1.3 vs posttest mean 13.8, SD 0.9 t-statistic −5.5, P < .001) significantly improved after the intervention. Qualitative feedback from the students underscored the utility of the first-person perspective for teaching surgical technique. Conclusion. This study demonstrates that remote teaching of knot tying and simple suturing to medical students can be effectively implemented using a remote learning curriculum that was well received by the learners.

Discontinuing routine processing of screening urine cultures prior to elective joint arthroplasty resulted in substantial reduction in urine cultures ordered and antimicrobial prescriptions for asymptomatic bacteriuria, without any significant impact on incidence of prosthetic joint infection. This simple change would be scalable across institutions with potential for significant healthcare savings.

The pattern of global left hemispheric hypoperfusion seen in this case of HaNDL supports a hypothesis of secondary oligemia induced by a hemispheric wave of cortical spreading depression (CSD). However, the extension of hypoperfusion to the right ACA territory represents a phenomenon not previously reported in this field. We speculate that the direct spread of CSD-induced vasomotor changes across the anomalous vasculature could account for this finding. This case provides a valuable contribution toward understanding HaNDL pathophysiology and in doing so may also yield broader implications regarding neurophysiological principles of CSD.
