[THE ROLE OF SIMULATION IN SURGICAL TRAINING--A NEW ERA].

Surgical training, which was traditionally based on the apprentice model, is undergoing a fundamental change since the introduction of virtual reality simulators into the training program of surgical residents. With the introduction of these simulators we can expect to see an improvement in the surgical abilities of new surgeons and a decrease in costs--as seen in the aviation world. Virtual reality simulators include a visual and tactile interface which is meant to train young surgeons in full procedure before the actual surgery.

Endometrial ablation for the postmenopausal woman.

The postmenopausal woman with abnormal uterine bleeding is considered at risk for developing endometrial neoplasia or one of its precursors. She requires prompt evaluation of the endometrium followed by adequate treatment. In the subgroup of postmenopausal women taking hormone replacement therapy (HRT), the risk of abnormal bleeding is by far higher, is the main reason for discontinuing HRT, and deserves additional attention.

Immediate versus delayed treatment of perimenopausal bleeding due to benign causes by balloon thermal ablation.

Study Objective: To compare the effectiveness and safety of thermal balloon ablation without pretreatment with endometrium-thinning agents compared with delayed ablation with pretreatment for women with perimenopausal menorrhagia.

Design: Prospective, randomized, controlled trial (Canadian Task Force classification I).

Setting: Hospital-based ambulatory medical center.
