Esophageal candidosis in progressive systemic sclerosis: occurrence, significance, and treatment with fluconazole

Esophageal mucosal brushings from 51 consecutive patients with progressive systemic sclerosis (PSS) (group I), 18 PSS patients continuously treated with high-dose ranitidine or omeprazole (group II), 34 controls referred to the outpatient clinic for endoscopy (group III), and 10 patients receiving long-term potent antireflux therapy for idiopathic gastroesophageal reflux (group IV) were cultured for Candida albicans. There were 44%, 89%, 9%, and 0% Candida albicans culture-positive patients in groups I through IV, respectively. Fifteen patients with candida esophagitis from group II were treated with fluconazole systemically. Eleven and 14 patients became culture-negative after 2 and 4 weeks' treatment, respectively. Three months after fluconazole withdrawal the recurrence rate was 100%. It is concluded that esophageal dysmotility predisposes for candidosis. Adding gastric acid inhibitory treatment to dysmotility enhances the risk significantly (p less than 0.01). The efficiency of fluconazole treatment was close to 100%, but so was the recurrence rate within a short period.

不同脑保护方法中炎症反应对脑组织的影响

目的 通过观察体外循环中采用不同脑保护方法时脑组织中各种炎性细胞因子的变化，探讨脑保护对炎症反应的影响。方法 将18只健康成年杂种犬随机均分为3组：常温体外循环组（normothermic cardiopulmonary bypass，NCPB组），深低温停循环组（deep hypothermic circulatory arrest，DHCA组），深低温停循环＋间断选择性顺行性脑灌注组（intermittent selective antegrade cerebral perfusion，ISACP，DHCA＋ISACP组）。术后检测犬脑组织的含水量，分离并取出海马，制备脑组织匀浆，采用放射免疫法测定白细胞介素-1β（IL-1β）和肿瘤坏死因子-α（TNF—α）的含量。在透射电子显微镜（TE）下检测海马脑组织的细胞形态学变化。结果 DHCA组的IL-1β和TNF—α含量明显高于NCPB组和DHCA＋ISACP组（P〈0．01），但NCPB组与DHCA＋ISACP组间比较差别无统计学意义（P〉0．05）；TNF—α和IL-1β含量与脑水肿的程度呈正相关（r=0．987，0．942；P〈0．01）。TE检查显示DHCA组超微结构破坏较严重，而NCPB组和DHCA＋ISACP组破坏较轻。结论 长时间DHCA会造成脑损伤，DHCA＋ISACP有一定的脑保护作用，IL-1β和TNF—α在长时间DHCA中对脑损伤起一定的作用。     

Ghrelin does not stimulate gastrointestinal motility and gastric emptying: an experimental study of conscious dogs

Ghrelin is a peptide that was discovered in endocrine cells of the stomach. However, its action in regulating the fasted and fed motor activity of the digestive tract is not fully understood. In the present study, we examined the effects of an intravenous (i.v.) injection of canine ghrelin on the physiological fasted and fed motor activities in the stomach, duodenum, jejunum and colon of freely moving conscious dogs. An i.v. injection of canine ghrelin released growth hormone in a dose-dependent manner; however, it did not stimulate the motor activity of the digestive tract in either the fasted or the fed state. Moreover, an i.v. injection of high-dose canine ghrelin significantly reduced the motility index in the gastric body in the fasted state. Ghrelin did not accelerate gastric emptying, either. These results differ from previous reports dealing with rodents. It is significant that such results were obtained in research with dogs, which are larger animals.     

Agreement between staff and service users concerning the clientele's mental health needs: a Quebec study.

OBJECTIVES: This article examines the differences found between clientele with severe mental health problems and their key health workers in terms of assessing service users' needs in 6 Quebec service areas. METHOD: We questioned 165 pairs of users and staff, using the Camberwell Assessment of Needs questionnaire. The profile of serious and overall problems encountered by clientele from each of the sites was compared. RESULTS: The sites with the greatest degree of user-staff agreement in identifying problems were also the ones where users considered that local services best met their needs. CONCLUSIONS: The study demonstrated that, in needs assessment, major differences exist between the perceptions of users and their key workers in the various sites. These differences can be explained in part by users' individual characteristics, by types of needs, by local particularities, and by service use.
