摘要：目的:后巩膜环切断术已被提倡用于视网膜中央静脉阻塞治疗。我们回顾了一些病例,这种手术显然产生了睫状后短和长动脉的切断或关闭,结果导致三角形脉络膜缺血区和永久的视网膜脉络膜病灶。设计:病例系例。安排:以临床为基地的视网膜玻璃体的会诊中心实施。病例:3例年龄从17至53岁患者的4眼,做了后巩膜环切断术以治疗视网膜中央静脉阻塞。主要结果测定:发现的内容来自完整的眼科学评价。结果:全部患者在视盘鼻侧都有卵圆形或三角形脉络膜缺血区和永久的视网膜脉络膜病灶。结论:施行此种手术有效的证据尚需要进一步研究。

摘要：Objectives: To evaluate the benefit of fluconazole prophylaxis in preventing i nvasive fungal infection in very low birth weight (VLBW) infants with central va scular access. Study design: A 3-year baseline period (1998 to 2000)was compare d with a subsequent 3-year period (2001 to 2003) during which a different proto col for preventing invasive fungal infection was used. All infants with a birth weight < 1500 g and with central vascular access were eligible for the study. Fl uconazole (Diflucan R)was administered for 28 days at a dose of 6 mg/kg every th ird day during the first week and daily after the first week. Results: There wer e no significant differences between the baseline and the fluconazole groups in demographic characteristics or risk factors for fungal infection. Fungal infecti on developed in 9 of the infants in the baseline group and in none of those in t he fluconazole group (P = .003). A trend of decreasing mortality rate between th e 2 groups (12.6%vs 8.1%; P = .32) was observed but was not statistically sign ificant. No adverse effects of fluconazole therapy were documented. Conclusions: Fluconazole prophylaxis appeared to be beneficial in preventing invasive fungal infection in VLBW infants.

摘要：目的前瞻性分析了既往5年内南京解放军第八一医院32例次经皮下隧道留置的带涤纶套血液透析用长期导管的使用寿命情况。有2种不同设计的导管参与了研究:HemoSplit(Bard),Permcath(Quinton)。方法我们使用Kaplan-Meier单因素分析来比较不同因素对导管寿命的影响,利用Cox多元回归分析比较各影响因素的相对重要性。结果我们发现在导管的使用寿命方面,是否首次置管对导管总体使用寿命无显著影响(P=0.897);置管途径中以右颈内静脉留置导管最佳(中位生存时间1101天);非糖尿病患者导管使用时限较糖尿病患者长(中位生存时间分别是1126天及898天,P=0.024);HemoSplit导管优于Permcath导管(中位生存时间分别是1126天及825天,P=0.126)。患者的年龄、性别对导管使用影响不大。Cox比例风险模型发现糖尿病及导管所在静脉的选择均为导管留置寿命的独立影响因素。结论临床医生在操作前应准确掌握可能影响导管使用寿命的因素并充分考虑到原发病和导管的置入途径。
