aortic dissection begins with the formation of a tear in the aortic intima, and it directly exposes an underlying diseased medial layer to the driving force of the intraluminal blood. this blood penetrates the diseased medial layer and cleaves the media longitudinally, thereby dissecting the aortic wall. herein, we report the case of a 38-year-old woman, who presented with chest pain and dyspne...

INTRODUCTION We report mid-term results from the endovascular treatment of acute thoracic aortic pathologies in a single center. METHODS We retrospectively interrogated our clinical database and identified the following patients who were treated for an acute thoracic aortic pathology during a 3-year period (January 2003 to February 2006) with the deployment of a thoracic endograft: 8 male pat...

To better understand the biomechanical mechanisms underlying the association between hyperkyphosis of the thoracic spine and risk of vertebral fracture and other degenerative spinal pathology, we used a previously validated musculoskeletal model of the spine to determine how thoracic kyphosis angle and spinal posture affect vertebral compressive loading. We simulated an age-related increase in ...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

introduction: traumatic chest injuries (tci) are one of the most common causes of referring to the emergency departments, with high mortality and disability. this study was designed to evaluate the diagnostic accuracy of ultrasonography versus chest x ray (cxr) in detection of hemo-pneumothorax for patients suffering penetrating tci. methods: the present cross-sectional study was performed to e...

ketamine is a promising alternative agent for pain control that offers benefit to traditional strategies, particularly in the setting of rib fracture. current pharmacologic therapies have clear adverse effects, and other options may be invasive, cost prohibitive, or marginally effective. we describe three consecutive patients with traumatic injuries including rib fracture for which a ketamine i...
