BACKGROUND:
Endovascular repair of mycotic aneurysm is an alternative to open repair if the patho-anatomy is suitable. The aortic size above and below the mycotic aneurysm may be small.METHODS:
A retrospective review was made of prospectively collected departmental computerised database.RESULTS:
Three oriental patients with juxta- and infra-renal mycotic aortic aneurysms with a small aortic diameter of 17 mm to 18 mm underwent successful emergency endovascular treatment using Cook® Zenith ESLE stentgrafts. These are ancillary devices aimed at iliac extensions usually.CONCLUSION:
This is to our knowledge the first case series of Cook® Zenith ESLE iliac component endografts for the treatment of aortic mycotic aneurysms with small aortae, and short- and mid-term results are encouraging.KEY WORDS: Endovascular, Mycotic, Small aorta, Oversizing, Cook®, Zenith ESLE Stentgrafts 相似文献94.
目的探讨骨性Ⅲ类错[牙合]手术与非手术边缘病例的颅面特征,为选择临床治疗方法提供参考。方法选择完成治疗的骨性Ⅲ类错[牙合]边缘病例,单纯正畸组13例,手术治疗组12例,统计分析2组病例治疗前的X线头影测量值。结果Mann-Whitney u检验显示2组下颌骨前颅底长度比Go-Me/S-N(P=0.026)、上下颌切牙的交角U1-L1(P=0.030)、Holdaway角(P=0.026)的差异有统计学意义,逐步判别分析后仅有Holdaway角能对2组进行预测区分,区分值为12°,总判别准确率为72%。结论制定骨性Ⅲ类错[牙合]边缘病例治疗计划时,下颌骨前颅底长度比、上下颌切牙的交角以及软组织的凹陷度是要重点分析的颅面结构项目,小于12°的Holdaway角可以作为需手术改善软组织侧貌的初步判定指标。 相似文献

Background
An inverse association between birth weight and the risk of developing type 2 diabetes (T2D) in adulthood has been reported. This association may be explained by common genetic variants related to insulin secretion and resistance, since insulin is the most important growth factor in fetal life. The objective of this study was to examine whether T2D gene polymorphism TCF7L2 rs7903146 is associated with growth patterns from fetal life until infancy. 相似文献96.
背景与目的:胶质瘤干细胞(glioma stem cell,GSC)在胶质瘤发展及治疗抗拒中发挥重要作用。我们以往的研究表明,新型STAT3信号转导通路抑制剂(STAT3 inhibitor,STI)WP1193能够诱导GSC产生细胞周期阻滞及凋亡。本研究旨在探讨STI是否能在体外诱导GSC产生自噬现象。方法:从手术切除的胶质母细胞瘤中分离及培养GSC。使用STI处理GSC。利用细胞计数法检测STI对GSC增殖的影响。使用Western blot检测自噬相关蛋白LC3的表达情况。吖啶橙染色后,利用荧光显微镜及流式细胞技术检测酸性自噬小体。使用透射电镜检测GSC中自噬小体。结果:STI剂量依赖性的抑制GSC的增殖。STI处理后,GSC中出现LC3表达的切换。STI处理后,GSC中出现自噬小体,且出现自噬小体细胞的比例增加。结论:STI能够在GSC中诱导自噬现象的产生。自噬在STI治疗中的意义及调节机制需要进一步的研究。 相似文献

Diffusion weighted imaging (DWI) and T2 weighted magnetic resonance imaging were performed on at least two occasions in 28 children presenting with stroke. In previous reports of DWI in human stroke, eventual infarction was observed (with only one exception) in all regions in which early DWI hyperintensity occurred. In the present report, two children had regions of DWI hyperintensity which did not progress to infarction. One patient who presented with right hemiplegia showed extensive high signal on DWI, with T2 evidence of tissue swelling but without hyperintensity. DWI changes persisted over weeks, with no imaging indication of infarction. This child recovered completely. A second child who had a major vessel infarct with concomitant regions of hyperintensity on T2 weighted imaging and DWI, also had DWI hyperintensity in an adjacent territory which did not develop any subsequent evidence of infarction. Thus in clinical practice DWI can demonstrate tissue which is compromised but not irreversibly so. 相似文献

Background
Studies that identify reasons for readmissions are gaining importance in the light of the changing demographics worldwide which has led to greater demand for hospital beds. It is essential to profile the prevalence of avoidable readmissions and understand its drivers so as to develop possible interventions for reducing readmissions that are preventable. The aim of this study is to identify the magnitude of avoidable readmissions, its contributing factors and costs in Hong Kong. 相似文献100.
