Semmelweis’ present day follow-up: Updating bacterial sampling and enrichment in clinical hygiene

Potentially dangerous antibiotic resistant contaminants have permanently penetrated at least well-off western populations. The danger is so evident that some hospitals have started to refuse accepting patients who carry such bacteria. Sampling and enrichment measures in hygiene monitoring must be updated as they are corner stones in handling the problems and safeguarding the health care units. Their patients, when exposed to microorganisms are strenuous to treat. Sometimes even this fails, if the infections are spreading in weakened patients. The present review summarizes currently used technologies and the abilities of bacteria to avoid detection. Improved protocols on environmental monitoring in healthcare units are required. They should be comparable with contamination control in industries. Actually these measures in health care should be even stricter because human lives are directly endangered as the resistance of especially elderly patients is low.     

The clinical encounter as local moral world: Shifts of assumptions and transformation in relational context

In this study we consider the process of the clinical encounter, and present exemplars of how assumptions of both clinicians and their patients can shift or transform in the course of a diagnostic interview. We examine the process as it is recalled, and further elaborated, in post-diagnostic interviews as part of a collaborative inquiry during reflections with clinicians and patients in the northeastern United States. Rather than treating assumptions by patients and providers as a fixed attribute of an individual, we treat them as occurring between people within a particular social context, the diagnostic interview. We explore the diagnostic interview as a landscape in which assumptions occur (and can shift), navigate the features of this landscape, and suggest that our examination can best be achieved by the systematic comparison of views of the multiple actors in an experience-near manner. We describe what might be gained by this shift in assumptions and how it can make visible what is at stake for clinician and patient in their local moral worlds—for patients, acknowledgment of social suffering, for clinicians how assumptions are a barrier to engagement with minority patients. It is crucial for clinicians to develop this capacity for reflection when navigating the interactions with patients from different cultures, to recognize and transform assumptions, to notice ‘surprises’, and to elicit what really matters to patients in their care.

子宫内膜萎缩疗法治疗青春期功血362例临床研究

目的：探讨子宫内膜萎缩疗法治疗青春期功血（DUB）的止血效果。方法：将362例平均分为观察组（采用炔诺酮、戊酸雌二醇联合疗法止血）和对照组（单用炔诺酮子宫内膜萎缩疗法止血），两组各181例，比较两组的止血效果。结果：观察组和对照组止血有效率分别为96．13％（174／181）和92．27％（167／181），两组比较差异无统计学意义（踟105）；观察组和对照组控制出血时间分别为（28．69±14．87）h和（29．72±15．34）h，两组比较差异无统计学意义（踟．05）。观察组和对照组的完全止血时间分别为（32．80±19．10）h和（47．30±18．60）h，两组比较差异有统计学意义（／9〈0．05）。观察组和对照组的住院天数平均为（6．10±2．80）d和（6．9±2．60）d，观察组住院时间短于对照组（P〈0．01）。结论：炔诺酮止血疗法和炔诺酮、戊酸雌二醇联合疗法治疗青春期功血效果均较好，但炔诺酮、戊酸雌二醇联合疗法治疗效果更佳。
