End-of-life Models and Emergency Department Care

Many people die in emergency departments (EDs) across the United States from sudden illnesses or injuries, an exacerbation of a chronic disease, or a terminal illness. Frequently, patients and families come to the ED seeking lifesaving or life-prolonging treatment. In addition, the ED is a place of transition-patients usually are transferred to an inpatient unit, transferred to another hospital, or discharged home. Rarely are patients supposed to remain in the ED. Currently, there is an increasing amount of literature related to end-of-life care. However, these end-of-life care models are based on chronic disease trajectories and have difficulty accommodating sudden-death trajectories common in the ED. There is very little information about end-of-life care in the ED. This article explores ED culture and characteristics, and examines the applicability of current end-of-life care models.     

Extragastrointestinal stromal tumor possibly originating from the prostate

We report a case of extragastrointestinal stromal tumor possibly originating from the prostate. The patient underwent radical prostatectomy because of no metastatic evidence. No recurrence and metastasis have been found during 14 months of follow up. To our knowledge, this may be the third such case published in a report in terms of pathological type.     

Use of the Arndt wire-guided endobronchial blocker via nasal for one-lung ventilation in patient with anticipated restricted mouth opening for esophagectomy.

Functional separation of the lungs may be accomplished by several methods. Patient with restricted mouth opening has limited options for one-lung ventilation. We report the use of wire-guided endobronchial blockade, a new tool for achieving one-lung ventilation in a patient with restricted mouth opening requiring nasotracheal, fiberoptic intubation for esophagectomy and reconstruction with gastric tube substitution.     

Early Designs for the Occlusal Anatomy of Posterior Denture Teeth: Part III

Part III of this series of articles, like Part II, reviews the pioneering efforts in the 19th century to improve the quality of artificial teeth. The focus of this article, unlike that of Part II, is specifically modifications in the design of the occlusal anatomy of the 19th century denture teeth, along with the theories of mandibular movement that inspired those modifications. This article concludes the introductory phase of this project, which seeks to unravel the confusing history of the development of (posterior) denture teeth.     

颈静脉球瘤的MR诊断

目的探讨MR检查在颈静脉球瘤诊断中的应用价值。方法对15例病变进行回顾性分析,重点分析其部位、信号及其侵袭性表现等情况。结果15例患者中,右侧病变8个(8/15),左侧7个(7/15);肿瘤形态为类圆形或不规则形,12例较大病变不同程度侵犯颈静脉孔区、乳突、岩骨、岩尖、斜坡等处骨质;肿瘤信号欠均匀,12个(12/15)肿块在MR平扫出现“盐和胡椒征”,以“胡椒”表现最为显著;13个肿块(13/13)均有明显强化,其中10个肿块出现“盐和胡椒征”。9例行MRA检查,颈内动脉和颈内静脉不同程度移位和包绕。结论根据肿瘤的部位、“盐和胡椒征”等MR表现,可在手术前正确诊断颈静脉球瘤。     

对代谢综合征病人疾病的认知程度及治疗依从性的调查

代谢综合征(metabolic syndrome,MS)是包括多种代谢紊乱的一组病理综合征。这些代谢紊乱之间具有密切而复杂的相互关系,是造成包括高血压病、糖尿病、心脑血管疾病在内的一组疾病的基础。MS患病率在世界范围内正以极快的速度增长,预防和治疗MS相关疾病的发生和发展,是目前备受关注的重大社会卫生问题[1]。笔者对119例MS病人进行MS认知程度的调查,分析影响MS病人治疗依从性的因素。1对象和方法1.1对象2003年6月—2005年6月我院内分泌科住院和门诊MS病人119例,均符合中华糖尿病学分会CDS(2004)MS诊断标准[2]。所有病人思维清晰,语言表…
