Training on synthetic ethylene-vinyl acetate bench model allows novice medical students to acquire suture skills.

Purpose: To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students.

Methods: Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of instructors, while group B (control) received a faculty-directed training based on books and instructional videos.

Effect of zafirlukast on capsular contracture around silicone implants in rats.

Purpose: To evaluate the effect of zafirlukast on capsular contracture around silicone implants by measuring the pressure within the implant, using a rat experimental model.

Methods: Forty adult female Wistar rats were used. Each one received two silicone implants, one with smooth-surface and the other with textured-surface.

Proposal of a synthetic ethylene-vinyl acetate bench model for surgical foundations learning: suture training.

Due to ethical and legal aspects involved in the handling of cadavers and animals the synthetic simulators are an alternative for learning how to suture technique plus the practice of various procedures such as incision and surgical flap. In this context, this paper describes and propose the use of a synthetic model manufactured from plates of ethylene-vinyl acetate (EVA) to teach primary surgical skills in medical students with no previous exposure to surgery. The model that provides the convenience of being easily reproducible, allowing the students in training can thus improve their skills before applying the technique in clinical practice.

Histologic analysis of zafirlukast's effect on capsule formation around silicone implants.

Background: The most common complication experienced by patients who have undergone mammary implant surgery is capsular contracture. This matter concerns physicians and patients, but to date, there is no effective way to avoid this complication. Surgical intervention usually is required.
