AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic ***:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ***:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan.

Peer-assisted learning to train high-school students to perform basic life-support

引用

World Journal of Emergency Medicine 2015年第3期6卷 186-190页

作者： Hyung Soo choi Dong hoon Lee Chan Woong Kim Sung Eun Kim Je Hyeok Oh Emergnecy Medicine Department Chung-Ang University Hospital 102 Heukseok-ro Dongjak-gu

BACKGROUND: The inclusion of cardiopulmonary resuscitation(CPR) in formal education has been a useful approach to providing basic life support(BLS) services. However, because not all students have been able to learn directly from certified instructors, we studied the educational efficacy of the use of peer-assisted learning(PAL) to train high-school students to perform BLS ***: This study consisted of 187 high-school students: 68 participants served as a control group and received a 1-hour BLS training from a school nurse, and 119 were included in a PAL group and received a 1-hour CPR training from a PAL leader. Participants' BLS training was preceded by the completion of questionnaires regarding their background. Three months after the training, the participants were asked to respond to questionnaires about their willingness to perform CPR on bystander CPR and their retention of knowledge of ***: We found no statistically significant difference between the control and PAL groups in their willingness to perform CPR on bystanders(control: 55.2%, PAL: 64.7%, P=0.202). The PAL group was not significantly different from the control group(control: 60.78±39.77, PAL: 61.76±17.80, P=0.848) in retention of knowledge about BLS ***: In educating high school students about BLS, there was no significant difference between PAL and traditional education in increasing the willingness to provide CPR to bystanders or the ability to retain knowledge about BLS.

通常而言,很少使用分歧稳定概念评价钢结构临界荷载,这类钢结构具有几何缺陷,并处于横向荷载导致的主弯矩作用下。这些案例中采用了基于极限荷载稳定性概念上的塑性区域和塑性铰分析。然而,这类分析需要大量的计算时间和复杂的理论,不适合实际设计。为此,提出一种弹塑性屈曲分析的新方法,旨在确定钢结构的临界荷载。此方法基于修正分歧稳定概念(运用切线模量方法确定)和柱强度曲线,运用梁柱交互作用公式,提出迭代特征值分析方法,计算主弯矩及轴力。该法的有效性和适用性,通过弹性屈曲分析和精细塑性铰分析进行评估。以具有几何缺陷的简支柱和4层板结构作为分析基准。结果显示:所提议的非弹性屈曲分析适用于评估钢结构的临界荷载和失效模式,可用于钢结构设计中临界荷载的确定。

Endoscopic submucosal dissection for early gastric cancer with undifferentiated-type histology:A meta-analysis

引用

World Journal of Gastroenterology 2015年第19期21卷 6032-6043页

作者： Chang Seok Bang Gwang Ho Baik In Soo Shin Jing Bong Kim Ki Tae Suk Jai hoon Yoon Yeon Soo Kim Dong Joon Kim Woon Geon Shin Kyung Ho Kim Hak Yang Kim Hyun Lim Ho Seok Kang Jong Hyeok Kim Jin Bae Kim Sung Won Jung Sea Hyub Kae Hyun Joo Jang Min Ho choi Department of Internal Medicine Hallym University College of Medicine College of Education Jeonju University

AIM: To evaluate the efficacy and safety of endoscopicsubmucosal dissection(ESD) for early gastric cancer(EGC) with undifferentiated-type ***: A systematic literature review was conducted using the core databases. Complete resection,curative resection, en bloc resection, recurrence and adverse event rate were extracted and analyzed. A random effect model was applied. The methodological quality of the enrolled studies was assessed using the Newcastle-Ottawa Scale. Publication bias was evaluated using a funnel plot, the trim and fill method, Egger's test,and a rank correlation ***: Fourteen retrospective studies between2009 and 2014 were identified(972 EGC lesions with undifferentiated-type histology). The total en bloc and complete resection rates were estimated as92.1%(95%CI: 87.4%-95.2%) and 77.5%(95%CI:69.3%-84%), respectively. The total curative resection rate was 61.4%(95%CI: 44.5%-75.9%). The overall recurrence rate was 7.6%(95%CI: 3.4%-16%).Limited to histologically diagnosed expanded-criteria lesions, the en bloc and complete resection rates were91.2% and 85.6%, respectively. The curative resection rate was 79.8%.CONCLUSION: In this analysis, ESD is a technically feasible treatment modality for EGC with undifferentiatedtype histology. Long-term studies are needed to confirm these therapeutic outcomes.

目的评价卵巢恶性肿瘤患者治疗后;F-FDG PET/CT显像的诊断和预后价值。方法回顾性分析卵巢恶性肿瘤患者治疗后的FDG PET/CT显像结果,计算PET/CT诊断肿瘤复发或第二原发肿瘤的准确性,并评价其对患者诊疗过程的影响。用Cox回归分析PET/CT显像结果与患者总体生存率的关系。结果 268例卵巢恶性肿瘤患者[平均年龄（50±13）岁]共行416次PET/CT显像,其中87次（21%）结果阳性,329次结果阴性;灵敏度、特异性、准确性、阳性预测值和阴性预测值分别为98.8%、98.2%、98.3%、93.1%和99.7%。362次随访显像中,38次（11%）的显像结果使患者治疗决策发生了改变;54次因临床有可疑征象而进行的PET/CT显像中,9次（17%）显像排除了肿瘤复发。PET/CT显像后进行了中位时间26.7个月的随访,24例（9%）患者在随访期内死亡。单因素分析结果发现,患者年龄、国际妇产科联盟（FIGO）分期、复发病史和PET/CT显像结果均与患者的总体生存率相关。多因素分析结果显示,PET/CT显像结果与患者的总体生存率相关（P<0.05）。结论卵巢恶性肿瘤治疗后FDG PET/CT是诊断复发和第二原发肿瘤的有效方法,其便于对患者采用更合适的治疗手段,并能帮助预测预后。
