AIM: To compare outcomes between single and dual en bloc(EB) kidney transplants(KT) from small pediatric donors. METh.DS: Monocentric nonprospective review of KTs from pediatric donors ≤ 5 years of age. Dual EB KT was defined as keeping both.donor kidneys attach.d toth. inferior vena cava and aorta, wh.ch.were th.n used as venous and arterial conduits for th. subsequent transplant into a single recipient. Donor age was less useful th.n eith.r donor weigh. or kidney size in decision-making for kidney utilization as kidneys from donors h.were not transplanted. Post-transplant management strategies were standardized in all ***: From 2002-2015, 59 KTs were performed including 34 dual EB and 25 single KTs. Mean age of donors(17 mo vs 38 mo, P h.(11.0 kg vs 17.4 kg, P = 0.046) and male donors(50% vs 84%, P = 0.01) were lower in th. dual EB compared to th. single KT group, respectively. Mean cold isch.mia time(21 h., kidney donor profile index(KDPI; 73% vs 62%) and levels of serum creatinine(SCr, 0.37 mg/d L vs 0.49 mg/d L, all P = NS) were comparable in th. dual EB and single KT groups, respectively. Actuarial graft and patient survival rates at 5-years follow-up were comparable. Th.re was one case of th.ombosis resulting in graft loss in each.group. Delayed graft function incidence(12% dual EB vs 20% single KT, P = NS) was sligh.ly lower in dual EB KT recipients. Initial duration of h.spital stay(mean 5.4 d vs 5.6 d) and th. one-year incidences of acute rejection(6% vs 16%), operative complications(3% vs 4%), and major infection were comparable in th. dual EB and single KT groups, respectively(all P = NS). Mean 12 mo SCr and abbreviated MDRD levels were 1.17 mg/d L vs 1.35 mg/d L and 72.5 m L/min per 1.73 m^2 vs 60.5 m L/min per 1.73 m^2(both.P = NS) in th. dual EB and single KT groups, respectively. CONCLUSION: By transplanting kidneys from young pediatric donors into adult recipients, one can effectively

本科学声明面向为短暂性脑缺血发作(transient isch.mic attacks,TIA)患者提供医疗诊治的临床医生和相关医疗卫生人员。采用正规的证据复习方法对1990-2007年7月期间Medline数据库进行系统的文献检索,并运用证据表、汇总分析和病例资料的合并分析,对数据进行综合处理。本文支持以下基于组织学的TIA定义:局灶性脑、脊髓或视网膜缺血引起的短暂性神经功能障碍发作,且无急性脑梗死。TIA患者的近期卒中风险较高,可根据临床量表、血管影像学和磁共振弥散加权成像进行风险分层。诊断推荐包括:TIA患者应在发病24h.接受神经影像学评价,最好是应用包括弥散序列在内的MRI;应进行无创性颈部血管成像检查,最好是无创性颅内血管成像;对于未能确定血管病因的患者,TIA发病后应尽快进行心电图检查,也应考虑持续心电监测和超声心动图检查;应进行常规血液化验;对于发病72h.就诊并且ABCD^(2)评分≥3分(提示近期复发风险较高)或在门诊不能迅速完成诊断评价的TIA患者,应收入院治疗。
