Impact of video game genre on surgical skills development: a feasibility study.

Background: The playing of video games (VGs) was previously shown to improve surgical skills. This is the first randomized, controlled study to assess the impact of VG genre on the development of basic surgical skills.

Materials And Methods: Twenty first-year, surgically inexperienced medical students attended a practical course on surgical knots, suturing, and skin-flap technique.

Tissue expander capsule for abdominal wall in autologous breast reconstruction.

Adjuvant treatment planning can change after breast cancer resection and definitive pathological examination. Radiation therapy is often chosen as a supplementary treatment. Rectus abdominis-based muscle flaps are one of the main choices when breast reconstruction plans must be changed from implant-based to autologous methods.

Is the recipient vein really the main concern? A cohort study of head and neck reconstruction.

The aim of this study was to verify the role of the venous drainage system in the pathogenesis of complications in microsurgical head and neck reconstruction. In a nonrandomized cohort study, 52 consecutive cases of complex head and neck microsurgical reconstruction were evaluated. The patients were divided in two groups based on the treatment: the deep (DVDG; n = 30) and superficial (SVDG; n = 22) venous drainage groups.

The role of ischemic preconditioning at the gracilis muscle of rats in the early phase of reperfusion injury.

Purpose: Verify the role of ischemic preconditioning (IPC) in ischemia and reperfusion injury on gracilis muscle of rats.

Methods: Wistar rats (n=30) were distributed in three groups, I/R and IPC groups were subdivided concerning ischemia time. A near-amputation model of the posterior limb was produced by a hip joint level incision, preserving the vascular bundle and the femur bone and ischemia was induced for 2 h and 4 h, G-I 2 h/R (n=6) and G-I 4 h/R (n=6), followed by 1 h of vascular reperfusion.
