Surgical outcomes of partial nephrectomy for renal cell carcinoma: A joint study by the Japanese Society of Renal Cancer

OBJECTIVE: A joint study was undertaken by the Japanese Society of Renal Cancer to investigate the present status of partial nephrectomy in Japan and to speculate about what may be the indications for partial nephrectomy in patients with renal cell carcinoma. METHODS: Data were tabulated for 469 patients from participating medical institutions and various clinical factors were investigated with regard to disease progression (local recurrence and distant metastasis). RESULTS: Disease progression was observed in 21 patients (4.5%). No significant relation to disease progression was observed for sex, laterality, tumor histology, grade and tumor size. Although patients with solitary tumors displayed excellent prognosis irrespective of tumor diameter, patients with multiple tumors displayed a high likelihood of disease progression. Patients older than 77 years old and patients with imperative indication were found to have a poorer prognosis. CONCLUSION: In patients with solitary tumors, partial nephrectomy can be actively performed, even if the patient displays elective indications and the tumor is >4 cm in diameter. In patients displaying multiple tumors with imperative indications, the decision whether to perform partial nephrectomy should be made by the patients and their physicians after considering the impact on curability and the quality of life.     

Long-term results of first-line sequential high-dose carboplatin, etoposide and ifosfamide chemotherapy with peripheral blood stem cell support for patients with advanced testicular germ cell tumor

OBJECTIVE: Standard chemotherapy shows relatively low long-term survival in patients with poor-risk testicular germ cell tumor (GCT). First-line high-dose chemotherapy (HD-CT) may improve the result. High-dose carboplatin, etoposide, ifosfamide chemotherapy followed by autologous peripheral blood stem cell transplantation (PBSCT) was investigated as first-line chemotherapy in patients with advanced testicular GCT. METHODS: Fifty-five previously untreated testicular GCT patients with Indiana 'advanced disease' criteria received three cycles of bleomycin, etoposide and cisplatin (BEP) followed by one cycle of HD-CT plus PBSCT, if elevated serum tumor markers were observed after three cycles of the BEP regimen. RESULTS: Thirty patients were treated with BEP alone, because the tumor marker(s) declined to normal range. Twenty-five patients received BEP and HD-CT. One patient died of rhabdomyolysis due to HD-CT. Three and six (13% and 25%) out of 24 patients treated with BEP and HD-CT achieved marker-negative and marker-positive partial responses, respectively. The other patients achieved no change. Fifteen (63%) are alive and 14 (58%) are free of disease at a median follow-up time of 54 months. Severe toxicity included treatment-related death (4%). CONCLUSIONS: HD-CT with peripheral stem cell support can be successfully applied in a multicenter setting. HD-CT demonstrated modest anticancer activity for Japanese patients with advanced testicular GCT and was well tolerated. This regimen might be examined for further investigation in randomized trials in first-line chemotherapy for patients with poor-risk testicular GCT.     

多济敷对面部磨削创面愈合的临床疗效观察

目的：本研究采用多济敷外用于面部皮损磨削术后创面,观察其对创面愈合时间、皮肤色素沉着等的变化。方法：采用区域神经阻滞或局部浸润麻醉,对不同类型的面部皮损34例进行皮肤磨削治疗,术后创面应用多济敷或凡士林纱布作为底层敷料包扎创面,术后换药一次,保留底层敷料。结果：2001年8月至2003年9月间,通过自身对照,34例面部磨削术后采用多济敷治疗组较凡士林纱布组创面愈合时间缩短(P＜0．05),经过6个月至2年的随访,皮肤色素沉着也有明显改善。结论：多济敷有利于缩短面部磨削术后创面愈合时间,改善面部色素沉着,外观满意。

间接免疫荧光法检测婴幼儿急性下呼吸道合胞病毒感染的特异性IgM

本文对1984年1～3月和1985年3～8月共107例急性下呼吸道感染的住院患儿,采用间接免疫荧光法检测其急性期血清抗RSV特异性IgM抗体,并与病毒分离和/或中和试验比较,敏感性为82.1％,特异性为71.8％。RSV感染患儿发病后3天内大多数病例即可从血清中检测出RSV-IgM,因此该法具有早期诊断价值。     

“肠梗”治疗粘连性肠梗阻425例

本文对采用自行研制的中草药浓缩剂“肠梗”治疗的粘连性肠梗阻４２５例进行临床分析。根据不同的病理及临床特征将其分为三种类型，其中广泛粘连型是“肠梗”治疗的最佳适应症，粘连扭转型是其禁忌证。并对中转手术的指征、时间等问题进行了讨论。认为该方法具有简单易行、安全可靠、成功率高的特点，是一种易于推广的治疗粘连性肠梗阻的有效方法，具有较高的临床实际应用价值     

用视诱发电位和富里叶变换作视力客观估计

目的:研究用图形视觉诱发电位(PVEP)和离散富里叶变换(DFT)作视力客观估计的方法。方法:检测对象为33只正常眼。用翻转频率为10次/秒,条纹张角分别为30、20、18、12、10、6、4和2弧分的垂直方波光栅图形刺激,记录相应的稳态图形视诱发电位。用离散富里叶交换提取WEP频谱中10Hz成分的幅值。以光栅条纹张角为横坐标、相应的VEP频谱幅值为纵坐标作关系曲线,取阈值附近的近似线性部分的数据点作直线回归,用外推法求得阈值和视力。结果:比较VEP所测之视力与用国际标准视力表所测之视力,可见在本研究中70％的受检眼VEP视力估计较准确。结论:用本研究中的VEP技术客观地测量视力可靠性较高。眼科学报1997;13:59～61。     

双头加压螺纹钉贴股骨距内固定治疗股骨颈骨折

在Ｘ光电视下采用双头加压螺纹钉贴股骨距内固定治疗新鲜股骨颈骨折４２例，随访平均２．５年，其中１６例随访３年以上，骨折愈合率９５．２％，骨折不愈合并股骨头缺血性坏死率４．７６％。认为加压螺纹钉贴股骨距内固定可使钉的受力由较大剪应力变为较大轴向力承受，减少骨折处的剪应力，并加压于骨折端能促进骨折愈合。具有操作简单、进钉准确、创伤小、固定牢靠、并发症少等优点。
