Renal Cell Carcinoma in a Horseshoe Kidney and Preoperative Superselective Renal Artery Embolization: A Case Report

Only rarely is renal cell carcinoma encountered in a horseshoe kidney. This is a case report on renal cell carcinoma in a horseshoe kidney, in which superselective renal artery embolization was performed preoperatively. CT and digital subtraction angiography revealed a horseshoe kidney with a 3-cm tumor in the left side. Superselective renal artery embolization of the tumor was performed as a prerequisite procedure for the organ-preserving surgery of simple enucleation. Preoperative superselective renal artery embolization can be an effective tool to facilitate organ-preserving surgery in a horseshoe kidney.

Neuro-toxic interaction in alcohol-treated,thiamine-deficient mice

Summary Groups of adult male mice were either fed a thiamine-deficient diet for 10 weeks and thereafter treated with ethanol by making them inhale vapourized cane spirit for 10 weeks, or given both treatments simultaneously. The brains of these mice were then searched for degeneration using both light and electron microscopy. No degenerating nerve cells were observed in any animal in the cerebral cortex, hippocampus, cerebellum, olfactory bulbs, midbrain or hindbrain. However, axon terminal degeneration was seen in the olfactory bulbs and deep cerebellar nuclei in mice given the combined treatment. No cerebellar degeneration was found and only little degeneration was present in the olfactory bulbs of mice given the two treatments at different times. Thus, the combined treatment of alcohol and thiamine deficiency produced more brain damage than the sum of that produced by the two treatments given separately. This represents the first experimental in vivo demonstration of a biochemical interaction between these two factors in alcohol-related brain damage. The findings of long-term animal treatment with models using thiamine antagonists are compared.Supported by the special Research Fund Programme of Monash University (Post-Doctoral Fellowship)     

达利珠单抗预防致敏受者肾移植后排斥反应的临床研究

目的　探讨用达利珠单抗诱导治疗预防致敏受者肾移植后急性排斥反应的有效性与安全性。方法　将 36例群体反应性抗体为 30 %～ 5 0 %的致敏受者随机分为舒莱组和对照组 ,各 18例 ,舒莱组患者于移植术前 2h和术后第 4d接受达利珠单抗 (2 0mg/次 )诱导治疗 ,两个组术后均以环孢素A、霉酚酸酯和皮质激素预防排斥反应。结果　舒莱组术后 3个月内的急性排斥反应发生率明显低于对照组 (P <0 .0 1) ;术后 2～ 4周内对照组平均每日皮质激素用量明显高于舒莱组 ;两个组人 /肾 1年存活率的差异无显著性 ;舒莱组术后肾功能的恢复较对照组快 ,但差异无显著性 ;舒莱组术后1周内CD2 5 淋巴细胞数明显降低 (P <0 .0 1) ;未观察到达利珠单抗的相关不良反应。结论　在合理筛选供受者的基础上 ,致敏受者肾移植前接受达利珠单抗诱导治疗可降低术后急性排斥反应的发生率 ,且较为安全。     

昆明城区、大理农村7月～7岁儿童铁缺乏调查分析

目的 :了解昆明城区及大理农村 7月～ 7岁儿童目前的铁缺乏水平 ,进一步展开对儿童铁缺乏症的防治 ,降低儿童营养性缺铁性贫血的患病率 .方法 :采用抽样调查的方法对两地 7月～ 7岁儿童共 96 9名进行血清铁蛋白 (SF)、锌原卟啉 (ZPP)、血红蛋白 (Hb)实验室检查 .结果 :7月～ 7岁儿童的总铁缺乏检出率为 2 5 1% ,铁减少检出率为 19 0 % ,贫血患病率为 6 1% ;男女童患病率在 1岁以前差别较大 ,1岁以后差别不明显 ;各年龄组患病率以 7月～ 1岁组最高 ;早产儿、低出生体重儿童患病率相对较高 ;铁缺乏的儿童营养不良的患病率高于正常儿童 .结论 :儿童缺铁性贫血仍要引起重视 .在防治中要抓重点人群 ,除改变膳食结构和饮食习惯 ,对目标人群要适当补充铁剂预防     

肾癌合并静脉瘤栓的外科治疗效果观察

目的 观察肾癌根治性切除加瘤栓取出术治疗肾癌合并静脉瘤栓的效果。方法 总结8例肾脏恶性肿瘤合并静脉瘤栓患者的临床及病理资料。男7例，女1例。平均年龄58岁。右侧7例，左侧1例。Robson分期Ⅲ期5例，Ⅳ期3例。瘤栓类型：肾静脉型1例，肝下型4例，肝上型3例。结果 7例患者行肾肿瘤根治性切除加瘤栓取出术，1例行右肾肿瘤及右肾上腺根治性切除术，腔静脉瘤栓放射治疗。1例瘤栓达右心房者术中死亡。随访7例，3例分别存活2、4和22个月，均死于远隔转移。4例术后已随访12、14、25和47个月者现仍无瘤存活。结论 肾肿瘤根治性切除加瘤栓取出术是治疗肾癌合并静脉瘤栓的有效方法。     

肾创伤的生物力学性质及其临床特点

目的总结肾创伤生物力学性质及其临床特点。方法回顾本院2000年1月至2006年1月间收治的326例肾创伤病例,分析创伤过程中生物力学因素发挥的临床效应。结果随着暴力动量的增大,肾创伤等级、肾切除率及死亡率均随之增高,有统计学意义(P＜0．05)。钝性暴力相对于锐性更容易造成闭合伤和合并伤,且肾切除率低,差异有统计学意义(P＜0．01)。后腰着力的肾伤情重于腹部正面或侧面着力,且合并伤发生率低(P＜0．05)。创伤瞬间速度变化的趋向对伤情等级、肾切除率及死亡率无明显影响(P＞0．05)。结论肾创伤过程中暴力的生物力学性质与其临床表现紧密相关。     

移植肾自发性破裂(附15例报告)

目的：总结移植肾自发性破裂的病因，临床表现，诊治及预防，方法：15例患者中，手术探查12例（9例保留移植肾，用明胶海绵填压或医用粘合胶粘贴联合减压，引流处理，3例切除移植肾），3例保守治疗。结果：移植肾切除3例患者行血液透析维持，手术保留移植肾9例和3例保守治疗患者痊愈出院，其中2例手术保留移植肾患者分别于出院98d和6个月因肺部感染，心衰死亡，其他病例随访3－31个月，平均19个月，肾功能均良好，结论：移植肾自发性破裂发生的确切原因尚未清楚，结合临床症状行B超检查对确诊此症价值较高，及时发现，尽早行内，外科联合处理对于移植肾破裂的治疗是重要的，明胶海绵或医用粘合胶粘贴联合减压，引流是一种有效的治疗方法，另外，预防也是一重要环节。     

Pregnancy outcome in Factor XI deficiency: incidence of miscarriage, antenatal and postnatal haemorrhage in 33 women with Factor XI deficiency

Pregnancy complications in women with Factor XI deficiency were assessed in this retrospective analysis. All nonnulliparous women registered with Factor XI deficiency in the East Midlands region were included. Each woman was classified into 'bleeder' or 'nonbleeder'. Rates of antenatal and postnatal bleeding and miscarriage rate were recorded. A total of 33 women had 105 pregnancies. Pregnancy and delivery was uneventful in 70% of the cases. Postpartum haemorrhage (PPH) appears increased in women with a 'bleeding' phenotype with a highly significant difference between 'bleeders' and 'nonbleeders' (relative risk [RR] 7.2; CI 1.99–25.9). Miscarriage rate appeared unchanged. We conclude that PPH is increased in a subgroup with a bleeding phenotype. Larger studies are needed to define the underlying factors.
