结肠非低张双重造影的应用

本文应用结肠非低张双重对比灌肠造影诊断结肠病变,这是一种简单的方法。本文根据150例的实践径验介绍了技术、病人的准备、有关造影剂的问题和正常所见,并通过具体的病例阐述了结肠非低张双重对比检查的临床应用价值,并指出了本法的不足之处。     

PRENATAL DIAGNOSIS Ⅰ. EARLY DIAGNOSIS OF OPEN NEURAL TUBE DEFECTS BY QUALITATIVE ACETYLCHOLINESTERASE ISOENZYME IN AMNIOTIC FLUID

The measurement of amniotic fluid (AF) acetylcholinesterase isoenzyme (AChEI) is a relatively new method for early diagnosis of open neural tube defects (NTDs). As quantitative methods are of unproven reliability at present, the authors used a high resolving power qualitative method-vertical slab polyaerylamide gel electrophoresis. The benefits of this technique are: simplicity of operation, accuracy, unsophisticated equipment, and easily available reagents. Combined results of 9 NTDs studies revealed that samples from early pregnancy gave more accurate results than those from late pregnancy.     

Factors influencing survival of reconstructions. Consensus report of Working Group 2

Abstract: In order to evaluate the level of evidence of factors influencing the survival of reconstructions, systematic reviews of the relevant literature were prepared by a group of rapporteurs. The review papers were circulated to the members of the group before the conference and formed the basis for group and panel discussions. Subsequently, modifications were added to the review papers, and suggestions for consensus statements concerning the following topics were prepared and again critically reviewed in the group and in the plenum: Impact of (i) periodontal disease on the survival of tooth-supported reconstructions, (ii) post-surgical factors as supportive therapy on the survival of implant supported reconstructions, (iii) technical and/or biological complications on the survival of different types of reconstructions, (iiii) material choice for reconstructions on the survival of single crowns and fixed dental prostheses.     

跳水运动员颈椎损伤的生物力学研究

作者通过在新鲜成人颈椎标本上做了椎体静力性负荷和动力性负荷实验,表明颈椎在后伸位应力为前屈位的50%,最大应力位于颈椎4-6,是跳水运动员头颈部入水时引起颈椎致伤的生物力学因素。

耳源性脑疝25例临床分析

耳源性脑疝25例,抢救成功者19例。采用单纯脑脓肿穿刺抽脓抢救脑疝6例,仅1例成功;开颅减压术抢救脑疝20例,18例抢救成功。本组临床实践和文献报道都说明耳源性脑疝一旦发生应即刻行开颅减压术,能卓有成效地抢救生命     

Die Bedeutung von Assessments in der Ausbildung diplomierter Rettungssanitäter

Learning and exams are closely interconnected. Test elements should accompany the learning process and not only serve to complete the training period. Examinations should be oriented toward the ideas learned and the forms of instruction used. However, the significance of examinations during the training period for emergency medical technicians is hardly ever addressed in the literature. All of the procedures that serve to evaluate the students’ performance are subsumed under the term “assessments.” This contribution presents the tasks of assessments and their requirements for occupational training of certified emergency medical technicians. It also offers a suggestion to develop a modern testing concept.
