Uveal effusion syndrome complicated by anterior ischemic optic neuropathy

We report on a case of idiopathic uveal effusion syndrome complicated by AION. To our knowledge such an association hasn't been previously described. We suggest that scleral thickening caused obstruction of vortex veins followed by uveal effusion and compression of posterior ciliary arteries within their intrascleral tract, leading to AION. Nevertheless it can't be excluded that AION was the result of mechanical compression on ciliary vessels of optic disc by choroidal detachment.

A new technique for the treatment of lumbar far lateral disc herniation: technical note and preliminary results

A newly designed technique for a minimally invasive approach to the laterally herniated disc is presented. Fifteen patients suffering from far lateral disc herniation (extraforaminal) were operated according to this technique. Through a small skin incision (1.5 cm), the paraspinal muscles are spread by dilators, until a working channel of 9 mm inner diameter and 11 mm outer diameter can be placed. The next steps are done through this channel using the surgical microscope. No bone resections are necessary and the facet joints are left untouched. However, partial resection of the intertransverse ligament may be necessary. The mean follow-up period for these 15 patients was 11.5 months, and they were evaluated by using the visual analogue scale (VAS) and the Oswestry Disability Index (ODI). The average surgical time was 43 min. The ODI improved from 30.6 (preoperative) to 14.3 (postoperative). The VAS of leg pain improved from 7 (preoperative) to 3.6 (postoperative), which represented a statistically significant improvement at the significance level of (P<0.01). No intra-operative or early postoperative complications occurred. However, one recurrence did occur, which was treated by the same technique. This technique combines the advantages of three-dimensional visual control (operating microscope) with the minimal surgical trauma of endoscopic techniques, while avoiding some of the shortcomings of both the microsurgical and endoscopic techniques.     

Relapse rate and outcome of ANCA-associated small vessel vasculitis after transplantation.

BACKGROUND: Anti-neutrophil cytoplasm antibody-associated systemic vasculitis (AASV) is a rare disease and frequently leads to end-stage renal disease (ESRD). Potentially fatal disease activity can develop after the onset of ESRD or in transplanted patients despite the immunosuppressive effects of uraemia and rejection prophylaxis, respectively, leading to concern that such patients may have greater morbidity and mortality. METHODS: To assess the outcome of patients with AASV following kidney transplantation, a retrospective analysis was performed of nine patients with AASV at our unit who received renal transplants between 1987 and 2000. The renal survival of the patients was compared with a control population who received kidney transplants over the same period for causes other than AASV and diabetes mellitus. RESULTS: Nine patients with the diagnosis of AASV (five patients with Wegener's granulomatosis and four with microscopic polyangiitis) received eight cadaveric grafts and one live-related graft after a mean of 44 months from the start of dialysis. These patients had a mean age of 49.2 years at time of transplantation and they were followed up for a mean of 62 months post-transplantation. Two patients with Wegener's granulomatosis suffered a vasculitic relapse affecting the upper respiratory tract at 40 and 50 months post-transplantation, corresponding to a relapse rate of 0.04 per patient per year. The renal transplant function of vasculitis patients compared with 18 non-diabetic control patients who were transplanted at the same time was better in the vasculitis patients at some time points (P=0.054 at 6 months). CONCLUSIONS: There is a substantial relapse rate in the AASV population, especially affecting the upper respiratory tract and with increasing duration of follow-up. Nonetheless, renal transplantation is a good option for the treatment of vasculitis patients and their outcome compares favourably with that of other non-diabetic patients following transplantation.

视神经半损伤后复合神经营养因子辅助再生的动态PVEP研究

目的：探讨视神经（optic nerve,ON）损伤后的自然修复再生和用脑源性神经营养因子（BDNF）及睫状神经营养因子（CNTF）互补辅助再生的图形翻转视觉诱发电位（PVEP）变化特征，寻找ON有效再生的新途径。方法：将40只猫作为实验对象，术前随机平均分4组：正常对照组，球后ON半径切断组（ON1／2I）、ON半径切断并定时向玻璃体内玻璃体内注射BDNF和CNTF复合因子辅助再生组（ON1／2I＋BF）。经眶外侧入路行手术开眶，在球后5mm处测量ON直径数值，并用宝石卡尺刀行ON半径切断术。ON1／2I＋BF组在术后即日注射BDNF和CNTF复合液（10ng），并在以后注射等量BDNF和CNTF复合液，2次／w。在ON损伤后1个月、4个月和8个月，3次行PVEP动态检测，结果：在ON1／2损伤后1个月时，与N组相比，ON1／2损伤各组PVEP的N1－P1振幅显著降低和P1潜时延迟；ON1／2IT ON1／2I＋PS组与ON1／2I＋BF组比较，也出现了PVEP的N1－P1振幅降低和P1潜时的延迟。在ON1／2损伤后第4个月时，ON1／2I组和ON1／2I＋PS与N组比较，其PVEP的P1潜时显著延迟（P＜0．001，P＜0．001）和N1－P1幅度显著降低（P＜0．001，P＜0．001）。而ON1／2I＋BF组与N组比较，两者PVEP的P1潜时和N1－P1幅度差异虽然具有显著性（P＜0．05），但与ON损伤后1个月时同组动物的PVPEP测试结果比较，已开始出现恢复型曲线图谱，两者的差异亦有显著性（P＜0．05，P＜0．01）。在ON1／2损伤后8个月后，ON1／2I组和ON1／2I＋PS组的PVEP的P1潜时仍然显著延迟，N1－P1幅度仍然显著降低，未见明显的恢复型曲线图出现。而ON1／2I＋BF组PVEP的P1潜时和N1－P1幅度与ON损伤后4个月时的PVEP测试结果比较，差异却具有显著性（P＜0．01）；与ON1／2切断组和ON1／2I＋PS组比较，差异也具有显著性（P＜0．01），与N组比较，其PVEP的P1潜时未见延迟（P＞0．05），但N1－P1幅度仍低于正常对照组（P＜0．05）。结论：（1）视神经1／2损伤后可以添加条件因素辅助其再生，BDNF和CNTF对促进视神经损伤后的再生有调节局部微环境和互补促生长作用。（2）视神经1／2损伤前后，其有视觉电生理学的动态变化特征，主要表现为：在ON损伤后，PVEP的P1潜时重度延迟和N1－P1波幅值大幅度衰减，而当应用神经营养因子拮抗视神经损伤效应后的1个月、4个月和8个月时，则逐渐出现PVEP的P1潜时恢复和N1－P1波幅值的提高。这说明1／2损伤的ON在BDNF和CNTF的互补作用下，可以修复再生和恢复其视觉信息的传导功能。BDNF和CNTF对促进视神经损伤后的轴突再生有互补促生长作用。     

Early neuromuscular customized training after surgery for lumbar disc herniation: a prospective controlled study

A prospective and controlled study of training after surgery for lumbar disc herniation (LDH). The objective was to determine the effect of early neuromuscular customized training after LDH surgery. No consensus exists on the type and timing of physical rehabilitation after LDH surgery. Patients aged 15–50 years, disc prolapse at L4–L5 or L5–S1. Before surgery, at 6 weeks, 4, and 12 months postoperatively, the following evaluations were performed: low back pain and leg pain estimated on a visual analog scale, disability according to the Roland–Morris questionnaire (RMQ) and disability rating index (DRI). Clinical examination, including the SLR test, was performed using a single blind method. Consumption of analgesics was registered. Twenty-five patients started neuromuscular customized training 2 weeks after surgery (early training group=ETG). Thirty-one patients formed a control group (CG) and started traditional training after 6 weeks. There was no significant difference in pain and disability between the two training groups before surgery. Median preoperative leg pain was 63 mm in ETG and 70 mm in the CG. Preoperative median disability according to RMQ was 14 in the ETG and 14.5 in the CG. Disability according to DRI (33/56 patients) was 5.3 in the ETG vs. 4.6 in the CG. At 6 weeks, 4 months, and 12 months, pain was significantly reduced in both groups, to the same extent. Disability scores were lower in the ETG at all follow-ups, and after 12 months, the difference was significant (RMQ P=.034, DRI P=.015). The results of the present study show early neuromuscular customized training to have a superior effect on disability, with a significant difference compared to traditional training at a follow-up 12 months after surgery. No adverse effects of the early training were seen. A prospective, randomized study with a larger patient sample is warranted to ultimately demonstrate that early training as described is beneficial for patients undergoing LDH surgery.

目的探讨腰椎终板Modic改变在腰腿痛病例中的的临床分布特点，并探讨发生Modic改变的相关因素。方法选择2005年一年内因腰痛或坐骨神经痛行腰椎MR检查和常规X线检查的患者1223例，分析腰椎MRI中终板Modic改变在椎间盘节段、年龄和椎间盘退变分类中的分布特点及其相关因素。结果1223例6115个腰椎椎间盘中，257例（21．0％）320个椎间盘（5．2％）邻近终板发生M0dic改变，其中Ⅰ型48例（3．9％）51个椎间盘（0．8％），Ⅱ型206例（16．8％）266个椎间盘（4．3％）、Ⅲ型3例（0．2％）3个椎间盘（0．05％）。椎间盘节段L5S1 168个、L4-5 95个、L3-4 29个、L2-3 18个、L1-2 10个，发生率分别为13．7％、7．8％、2．4％、1．5％、0．8％。突出、脱出和滑脱病例发生率较高（辟0．00）。女性发生率高于男性（P=0．005）。40岁以上是Modic改变发生较多的年龄段（P=0．001）。椎间盘退变程度、椎间盘节段与年龄均和Modic改变具有显著相关性（P=0．000）。回归方程为Y=-5．955＋0．198A＋1．528L＋1．883D（Y为M0dic改变，A为年龄，L为椎间盘节段，D为椎间盘退变程度），P=0．000，EXP值：D=6．571，L=4．609，A=1．220。结论腰椎终板Modic改变和椎间盘退变、椎间盘节段和年龄之间存在相关关系，椎间盘退变是最重要的影响因素。Modic改变Ⅱ型最多，Ⅰ型次之，Ⅲ型最少；多发生于L4-5和L5S1椎间盘节段；女性高于男性；40岁以上是易发年龄。     

对CT所见腰椎间盘突出的重新鉴别与治疗观察

目的：因临床发现有些经ＣＴ检查有腰椎间盘突出的患者，其症状体征与ＣＴ结果不符。对１１２ＣＴ阳性者根据症状体征进行重新鉴别。方法：将ＣＴ阳性者根据“三种试验”分为阳性、阴性两组，再选压痛点作注射治疗。结果：两组治疗结果阴性组优良率较高。结论：ＣＴ结果可供参考，但不能作临床考虑的主要依据。对腰椎间盘突出症的诊断与治疗要以症状体征为主
