Fecal microbiota transplantation to eradicate vancomycin-resistant enterococci colonization in case of an outbreak

Objective

A rapid and worrying emergence of vancomycin-resistant enterococci (VRE) gut colonization is occurring worldwide and may be responsible for outbreaks, especially in healthcare facilities. While no efficient decolonization strategies are recommended, we assessed fecal microbiota transplantation (FMT) to eradicate VRE colonization.

阴道锥体训练联合生物反馈盆底肌治疗尿失禁老年人盆底肌康复研究现状

目的研究阴道锥体训练联合生物反馈盆底肌治疗尿失禁老年人的临床疗效及对盆底肌的影响。方法选取84例从2016年9月至2018年3月本院收治的尿失禁老年患者进行研究,以随机抽签法将其均分为联合组及对照组,每组42例。对照组予以常规盆底肌训练治疗,联合组则予以阴道锥体训练联合生物反馈盆底肌治疗。对比两组在临床疗效、治疗前后盆底肌力情况、治疗前后尿动力学参数指标水平以及生活质量变化情况等方面的差异。结果联合组与对照组在总有效率方面比较,前者高于后者(P<0.05)。治疗后联合组盆底肌力分级为Ⅳ级、Ⅴ级的人数占比相比对照组较高(P<0.05)。治疗后联合组与对照组在VLPP、PMUC水平方面比较,前者高于后者(P<0.05)。治疗后联合组与对照组I-QOL评分相比治疗前较高,且联合组相比对照组较高(P<0.05)。结论阴道锥体训练联合生物反馈盆底肌治疗老年尿失禁患者的疗效显著,有利于促进盆底肌力的恢复,且有效改善患者尿动力学参数,提高生活质量,具有较高的临床推广应用价值。     

反复粪便培养金黄色葡萄球菌阳性老年患者口服万古霉素效果评价

目的 通过探讨肠道非急性感染期反复粪便培养金黄色葡萄球菌阳性的老年患者口服万古霉素的效果，为此类患者提供一种潜在的治疗方案。方法 前瞻性分析吉林大学第一医院干部病房2015 年9 月～2018 年12 月收治的186 例肠道非急性感染期反复粪便培养金黄色葡萄球菌阳性的老年患者。根据是否口服万古霉素治疗分为万古组和对照组。收集两组患者的一般临床资料，比较两组患者试验前后万古霉素血药浓度、血常规、降钙素原（PCT）、C 反应蛋白（CRP），试验期间粪便培养结果、体温、抗生素使用情况。结果 试验治疗期间，万古组便培养转阴率高于对照组，差异有统计学意义（P＜0.05）；万古组发热率（29.75%）低于对照组的34.77%，差异有高度统计学意义（P＜0.01）；万古组抗生素使用率（4.49%）低于对照组的19.23%，差异有高度统计学意义（P＜0.01）。试验前两组白细胞、中性粒细胞计数、中性粒细胞比例、PCT、CRP 比较，差异无统计学意义（P＞0.05）；试验后万古组白细胞、中性粒细胞计数、中性粒细胞比例、CRP 低于对照组，差异有高度统计学意义（P＜0.01）。试验后万古组白细胞、中性粒细胞计数、中性粒细胞比例、CRP 低于试验前，差异有高度统计学意义（P＜0.01）。结论 口服万古霉素可能提高肠道非急性感染期反复粪便培养金黄色葡萄球菌阳性的老年患者粪便转阴率，减少发热及抗生素的应用，降低炎症细胞水平，可能是此类患者一种潜在的临床治疗方案。     

Treatment of fecal incontinence by temporary sacral nerve stimulation

Summary BACKGROUND: Sacral nerve stimulation (SNS) is an option for the treatment of fecal incontinence in patients with morphologically intact, but weak external anal sphincter. METHODS: In ten patients a percutaneous test-SNS was performed. Two patients suffered from fecal incontinence after surgery, one patient after incomplete leg palsy after traumatic spine injury and seven patients from idiopathic incontinence. Incontinence score, anorectal manometry and patient diary were performed before and after test-SNS. RESULTS: Intraoperative response (Bellows action) could be achieved in 90% of patients. Test-SNS was successful in 50% of patients. In these patients, resting pressure was increased by 100.1% and squeeze pressure by 84.5%. CONCLUSIONS: SNS is an effective therapy in a subset of patients with fecal incontinence. Fifty percent of patients tested are eligible for implantation of a permanent stimulation device.      

脑血管意外尿失禁的机制探讨

目的探讨脑血管意外引起尿失禁的可能机制。方法对42例诊断为脑血管意外伴有尿失禁的患者进行尿动力学检查(包括静止期尿道压测定、充盈期及排尿期膀胱尿道功能测定)并按Burney分类进行分析,同时研究病变部位、脑血管意外性质和病变半球侧与尿动力学的关系。结果42例脑血管意外患者中,表现为逼尿肌反射亢进者31例(73.8%):其中外括约肌无抑制性松弛19例(45.2%),逼尿肌-外括约肌不协调3例(7.1%),逼尿肌-外括约肌协调9例(21.4%);逼尿肌反射减低,外括约肌协调者11例(26.2%);无逼尿肌功能正常者。发生膀胱顺应性减低5例(11.9%),发生尿感缺失者11例(26.2%)。初感尿容量(140.00±46.97)ml;膀胱最大容量(293.20±60.71)ml;最大尿道闭合压(65.14±19.83)cmH2O。逼尿肌最大收缩力(Pdetmax)为(60.98±31.11)cmH2O;最大尿流率时逼尿肌压力(Pdet-Qmax)为(35.98±17.46)cmH2O;逼尿肌收缩时间(Tcon)为(86.07±36.09)sec;最大流量(Qmax)为(9.02±5.62)ml/s。中风后尿失禁患者其发病部位多见于基底节、皮层多灶以及额顶叶,脑出血与脑梗塞患者的尿动力学表现无明显差异,左右半球病变对尿动力学也无明显差异。结论脑血管意外后尿失禁的尿动力学异常主要为逼尿肌反射亢进,部分出现逼尿肌反射减弱,但感觉正常,感觉缺失者较少见;外括约肌功能以无抑制性松弛为主,其次为逼尿肌-外括约肌协调,少数出现不协调;较少出现膀胱顺应性降低。     

Diagnostic Validity of Fecal Occult Blood Tests for Detecting Gastroenterological Cancers

In order to estimate the diagnostic validity of chemical fecal occult blood tests, i.e. orthotolidine (Shionogi A) and guajac (Shionogi B) slides for detecting cancers of the esophagus, stomach and colorectum, the authors followed up all the examinees (n=3,449) of comprehensive medical check-ups at the Center for Adult Diseases, Osaka, by means of record linkage to the Osaka Cancer Registry's files. Then, diagnostic validity was calculated based on the results of two years' follow-up. Sensitivity for the respective cancers was 20.0%, 11.8% and 62.5% for Shionogi A, and 20.0%, 5.9% and 43.8% for Shionogi B slides. Likelihood ratio for the respective cancers was 1.4, 0.8 and 4.5 for Shionogi A, and 3.3, 1.0 and 7.5 for Shionogi B. Specificity was analogous among the three cancer sites, being 86% for Shionogi A and 94% for Shionogi B. These results suggest that the diagnostic validity of chemical occult blood tests for detecting cancers of the esophagus and the stomach is very poor, and therefore imply that close examinations of these sites for screening positives is unnecessary in mass screenings for colorectal cancer.
