OBJECTIVES/HYPOTHESIS To establish the effect of self-directed virtual reality (VR) simulation training on cadaveric dissection training performance in mastoidectomy and the transferability of skills acquired in VR simulation training to the cadaveric dissection training setting. STUDY DESIGN Prospective study. METHODS Two cohorts of 20 novice otorhinolaryngology residents received either s...

Acute type B aortic dissection comprises approximately one-third of all aortic dissection cases. Although this catastrophic cardiovascular condition was first described in the medical literature over two centuries ago, data on the optimal diagnostic and treatment modalities for type B dissection was slow to evolve throughout the latter half of the twentieth century, even as newer diagnostic tec...

STUDY OBJECTIVES Aortic dissection generally is an acute catastrophe. Rapid diagnosis is critical. We hypothesized that the quality of history taking contributes to the accuracy of diagnosis in patients with dissection. DESIGN Retrospective chart review of 83 patients, whose diagnosis of aortic dissection was confirmed by autopsy, surgery, CT scan, echocardiogram, or angiogram. The quality of...

BACKGROUND Sleep apnea syndrome (SAS) is an independent risk factor for hypertension which is a major risk factor for acute aortic dissection. The purposes of this study were to assess the prevalence of SAS in patients with acute aortic dissection, delineate the characteristics of patients who have acute aortic dissection with SAS. METHODS Of 95 consecutive patients with acute aortic dissecti...

Aortic Dissection To the Editor: We read with great interest the recent review on etiology, diagnosis and management in aortic dissection.1 In their discussion on diagnostic strategies, the authors state that useful biomarkers for aortic dissection are currently absent. We recently reported on 24 patients with acute aortic dissection in whom D-dimer, a degradation product of cross-linked fibrin...

Product dissection is a tool widely used in industry and academia as a means to understand the components of existing products and identify opportunities for redesign. Since dissection is widely practiced and typically occurs before idea generation, it has the potential to greatly affect the creativity of design outcomes. However, researchers have only just begun to explore how dissection effec...

INTRODUCTION Spontaneous dissection of the cervical artery is a rare non-atherosclerotic vascular disease of unknown aetiology and unclear pathogenesis that may be a cause of ischemic stroke in young adults. DIAGNOSIS Precise diagnosis of dissection of the cervical artery--carotid or vertebral--is possible with cervical axial magnetic resonance imaging and magnetic resonance angiography. TR...

OBJECTIVE To evaluate growth rate of aortic diameter true lumen, and false lumen in post endovascular aortic repair of aortic dissection. MATERIAL AND METHOD Between January 2005 and September 2010, 48 consecutive patients with aortic dissection were followed with computed tomographic angiography (CTA), including 18 post-surgical repaired type A patients and 30 type B (14 conservative treatme...

Cadaver dissection remains a cornerstone in the study of anatomical sciences by medical students. However, this activity can cause emotions that may affect learning outcomes. This study, which involved medical students of various cultural backgrounds, assessed their responses to dissection. Medicine I year students (n = 100) at Oakland University William Beaumont School of Medicine were invited...
