OBJECTIVE To evaluate the impact of bench model fidelity on the acquisition of technical skill using clinically relevant outcome measures. METHODS Fifty junior surgery residents participated in a 1-day microsurgical training course. Participants were randomized to 1 of 3 groups: 1) high-fidelity model training (live rat vas deferens; n = 21); 2)(More)
BACKGROUND This study examines the influence of visual-spatial ability and manual dexterity on surgical performance across 3 levels of expertise. METHODS Dental students, surgical residents, and staff surgeons completed standardized tests of manual dexterity and visual-spatial ability and were assessed objectively while performing the rigid fixation of an(More)
BACKGROUND Pilot studies of complex interventions such as a team checklist are an essential precursor to evaluating how these interventions affect quality and safety of care. We conducted a pilot implementation of a preoperative team communication checklist. The objectives of the study were to assess the feasibility of the checklist (that is, team members'(More)
BACKGROUND Ineffective team communication is frequently at the root of medical error. The objective of this study was to describe the characteristics of communication failures in the operating room (OR) and to classify their effects. This study was part of a larger project to develop a team checklist to improve communication in the OR. METHODS Trained(More)
OBJECTIVE Surgical skills laboratories have become an important venue for early skill acquisition. The principles that govern training in this novel educational environment remain largely unknown; the commonest method of training, especially for continuing medical education (CME), is a single multihour event. This study addresses the impact of an(More)
BACKGROUND We previously reported that a particular type of visual-spatial ability, mental rotation of visual forms, correlates with surgical performance in residents. In the current study, we used functional magnetic resonance imaging (fMRI) to identify patterns of cortical activation associated with mental rotation ability in those same residents. (More)
Seminal plasma is a fluid that originates from the testis, epididymis,prostate, and seminal vesicles, and hence, proteomic studies may identify potential markers of infertility and other diseases of the genito-urinary tract. We profiled the proteomes of pooled seminal plasma from fertile Control and post-vasectomy (PV) men. PV seminal plasma samples are(More)
INTRODUCTION Controversy exists regarding testosterone replacement therapy (TRT) in men following radical prostatectomy (RP). Many clinicians are hesitant to offer patients TRT after an RP, out of concern that the increased androgen levels may promote tumor progression or recurrence from residual tumor. Recently, several small studies have demonstrated the(More)
INTRODUCTION : Varicocele remains the most commonly identified correctable cause of male factor infertility. Surgical correction is the most commonly performed technique to treat varicoceles with a technical failure rate of less than 5%. An attractive alternative to surgery is the selective catheterization and embolization of the gonadal vein. This data are(More)
