Functional outcome of a U-shaped ileocystoplasty (the Camey I procedure) in cancer of the bladder. Apropos of 14 cases

The authors studied postoperatively fourteen men who underwent urinary diversion with a Camey ileal bladder for bladder cancer in association with radical cystoprostatectomy, from March 1986 to June 1988. Mean follow-up was 19.5 +/- 9 months. Three patients died (21.4%), two other patients are alive with metastases. Ureteral reflux and upper tract dilatation occurred in 14.3 and 28.6% of the renal units, respectively. Daytime continence was achieved in 92.9% of the patients (13 patients), frequently 6 months after the operation. Nocturnal incontinence was almost universal (1 patient circumvented this problem by getting up to void every three hours during the night). Thirteen patients had urodynamic testing after the operation. Mean capacity of the ileal bladder was 344 ml with mean intraluminal pressure of 24 cm water. Mean urethral closing pressure was 49 cm water. Voiding was accomplished by abdominal straining concomitant with external sphincter relaxation. Post-void residual was less than 50 ml, except in one patient. The authors discuss these results and compare them to those of other studies.     

壮骨肾宝对实验性小鼠高脂血症的影响

目的观察由黄芪、白术、淫羊藿组成的复方制剂(壮骨肾宝)对实验性小鼠高脂血症的影响。方法用蛋黄乳液快速致小鼠单纯性高胆固醇血症和喂养高脂饲料致高脂血症模型 ,观察预防性给予不同剂量的壮骨肾宝后对血清总胆固醇(TC)、甘油三酯(TG)和高密度脂蛋白胆固醇(HDL -ch)的影响。结果壮骨肾宝中、高剂量能使血清TC降低(P<0.05),HDL -ch升高(P<0.01) ,但对TG的影响不大。结论壮骨肾宝有一定降血脂作用 ,并与剂量有关     

THE HISTOLOGIC FEATURES AND HISTOGENESIS OF MALIGNANT OVARIAN BRENNER TUMOR

Eight cases of malignant and 12 0f benign Bren- ner tumor are reported, patient ages ranged 31 69 and 39-53 years. The malignant tumor was bilateral in 6 0f 8 cases, and the benign in l of 12. The greatest diameter of the malignant tumors averaged around 11 cm, and the benign 10. Six of the malignant Brenner tumor patients died, one was lost to follow up, and one survived for 10 years. Pathologic and microscopic findings were pre- sented in some detail. Based on the analysis of the association between the histologic features and type of Mullerian epithelium, we believe that the so called Brenner tumor is in effect a tumor arising from the Mullerian epithelium with a tendency to differentiate into vaginocervical type epithelium.     

End-to-end oesophageal anastomosis: an experimental study in the rat

To study the effects of suture material, calibre and tension on the end-to-end oesophageal anastomosis, the cervical oesophagus of the rat was resected for 2.5 mm, 7.5 mm and 12.5 mm respectively in three groups of 60 rats each. End-to-end anastomosis was performed with either 6/0 silk, 6/0 polypropylene or 9/0 polypropylene sutures. There was no postoperative leakage. Mortality was mainly due to hair bolus obstruction at the site of anastomosis. There was no difference in mortality and anastomotic stenosis between groups with different resection lengths. Within each group, however, mortality and anastomotic stenosis were significantly higher in the subgroup of rats with 6/0 silk suture than that in the subgroup with 6/0 polypropylene sutures, which also had significantly higher mortality and anastomotic stenosis than the subgroup with 9/0 polypropylene sutures. Histological examination of the stenosed anastomosis showed disruption of muscle layers and submucosal thickening. It is concluded that the use of fine calibre sutures of biologically inert material would be preferred for the end-to-end anastomosis of the oesophagus.     

Recall of medication during pregnancy: Validity and accuracy of an adjusted questionnaire

Objective — To study the validity and accuracy of an adjusted questionnaire on medical drug use during pregnancy eight years after the pregnancy. Methods — The ability of a questionnaire on medication during pregnancy to detect actual use (= sensitivity) was tested against information collected 8 years previously (in 1983–1984) from 473 women with high-risk pregnancies who delivered at the University Hospital Nijmegen, the Netherlands. Results — For separate drug groups, the sensitivity varied between 5% and 91%. The timing of use was recalled moderately well. Although specific questions on drug groups did improve the sensitivity as compared to an earlier questionnaire, the improvement was not enough to make the questionnaire valid. High maternal education, low birth weight, low gestational age and a low 5-min Apgar score were related to better recall. The sensitivity of the questionnaire depended on the behavioural score of the child, implying recall bias. Conclusion — Questionnaire data on drug use during pregnancy obtained eight years after delivery are not a valid source of information.     

介入手术治疗异位妊娠12例临床分析

目的：探索一种治疗输卵管妊娠的微创介入手术，解决因其腹腔出血不能接受保守治疗或保守治疗失败的难题。保持输卵管完整及通畅，满足有生育需求的患。方法：对12例输卵管妊娠妇女行对侧股动脉穿刺，将导管超选择插至子宫动脉以甲氨喋呤(MTX)进行灌注及明胶海绵栓塞术。结果：本组病例中，术后10dB超复查孕囊脱落、吸收消失，栓塞后盆腔活动性出血停止。结论：介入治疗宫外孕输卵管妊娠，能有效杀灭胚胎组织，栓塞破裂血管止血效果明显，且能保持输卵管通畅。     

阿昔洛韦对单纯疱疹病毒脑炎小鼠脑细胞的保护作用

目的 了解单纯疱疹病毒脑炎(HSE)脑细胞结构的改变及药物的影响。方法 采用光学显微镜及透射电子显微镜观察HSE小鼠脑细胞结构的变化，并给予阿昔洛韦(ACV)及地塞米松(DEX)治疗，观察治疗后脑细胞结构的变化。结果 HSE小鼠脑神经细胞明显肿胀，核仁固缩，核内结构破坏，线粒体及高尔基体可见空泡样变性，核仁内可见病毒颗粒。用药物干预的小鼠脑神经细胞改变较轻微，未找到病毒颗粒；与单用ACV干预的小鼠相比，用ACV DEX干预的小鼠脑神经细胞及毛细血管周围水肿明显减轻。结论 HSE早期给予ACV DEX治疗，对HSE脑细胞结构有明显保护作用。
