Development of the Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) Faculty of Dentistry, University of Sydney

The Diploma in Clinical Dentistry (Conscious Sedation and Pain Control) of the Faculty of Dentistry, University of Sydney, is the first dedicated programme devoted to this field in Australia. Its development followed a decision by the Dental Board of New South Wales to require a formal qualification from the University of Sydney before dental practitioners could offer sedation and pain management in practice.
The programme is conducted at Westmead Hospital in conjunction with the Department of Anaesthetics, and satisfies the guidelines developed by the Royal Australasian College of Dental Surgeons and the Royal Australasian College of Surgeons.
The course is conducted either over one or two years, with block sessions requiring attendance at Westmead Hospital, together with assignments which are completed outside the block sessions. In this way, a dental practitioner enrolled in the programme is able to continue practice.
The block sessions need not be completed over one year, but must be completed within two years.     

INTRAOPERATIVE BLEEDING IN ENDOSCOPIC SUBMUCOSAL DISSECTION IN THE STOMACH AND STRATEGY FOR PREVENTION AND TREATMENT

To control intraoperative bleeding is an important key to successful endoscopic submucosal dissection. The distribution of submucosal vessels encountered during the procedure differ in places in the stomach and are roughly categorized into three groups: those located in the antrum, those in the lesser curvature, and those on the anteroposterior corpus wall which consists of oblique muscle layers. Therefore, knowledge of a suitable setting of diathermy and adjusted depth of dissection in the submucosal layer for each site is imperative. The combination of utilizing the distal attachment forced or swift coagulation (trimming with coagulation mode) have enable the treatment with an insulation tipped knife safer.     

A computer and video display based system for training eccentric viewing in macular degeneration with an absolute central scotoma

A new approach designed to establish the most suitable area for eccentric viewing and to teach and train patients with severe age-related macular degeneration (AMD) to use the eccentric viewing technique is described. Using a computer and video display based system, as well as software written specifically for this purpose, we investigated and trained ten consecutive patients with AMD. The patients were 80.1 ± 5.6 years old, on average. All of them had an absolute central scotoma. Mean visual acuity was 0.035 ± 0.016. After 30 min of testing, instruction and reading on the screen, followed by 2.6 ± 0.69 one-hour training sessions, on average, with the low vision therapist, reading newspaper and book texts with the aid of hyperoculars or aplanatic systems and a very short reading distance, the patients achieved a reading speed of 58.9 ± 19.7 words/min, significantly (p<0.001) higher than the initial speed when reading on the screen, 11.5 ± 4.5 words/min.     

开展卫勤指挥员任职培训的教学实践和体会

近几年来,第二军医大学卫生勤务学系承担了大量卫勤指挥员的任职培训任务.通过几年的理论研究和实践摸索,在教学的组织、管理、实施、保障等方面积累了一些经验,获得了一些具体的体会.我们认为要做好卫勤指挥员的任职培训教学必须明确培训目标,科学制定教学方案,精心安排教学内容,做好施训教员的培训,并在教学中注重合理运用教学方法,特别是要做好下部队调研,切实提高教学实效.     

彩超对人工心脏起搏的血液动力学研究

目的　本文采用彩色多普勒超声心动图研究了心脏起搏前、后的血液动力学变化 ,以评价不同起搏模式血液动力学效应。方法　对 32例植入人工心脏起搏器的患者 ,采用 M型、二维及多普勒超声心动图检测了心室按需起搏 (VVI)不伴室房逆传 (A组 )和伴室房逆传 (B组 )及房室顺序起搏 (AVP) (C组 )的左心结构、左室的泵血功能、左室收缩及舒张功能指标。结果　 1 .心室起搏 (VP)不伴室房逆传和房室顺序起搏(AVP)组起搏后的心输出量 (CO)明显增加 (P<0 .0 5〉,而 VP伴室房逆传组则 CO增加不明显 (P>0 .0 5 )。心搏量 (SV)各组均呈下降趋势 ,VP伴室房逆传者下降更明显。但起搏后三组间比较无显著差异 (P>0 .0 5 ) ;2 .VP后左室的收缩及舒张功能均有受损 ,而 AVP后主要损害左室的舒张功能 ,对左室收缩功能影响不明显 ;3.VP伴室房逆传者 ,起搏后血液动力学效应在三组间最差。结论　无论 VP还是 AVP起搏后由于心率的增加均可使CO增加 ,但对左室的功能均有不同程度的损害 ,VP伴室房逆传者最为明显 ,AVP损害程度三组间最轻。因此 ,AVP也并非真正的生理起搏器。临床上提倡埋植更接进生理状态的起搏器 (多部位心脏起搏 ) ,以保持良好的心功能状态     

小学生应对同伴冲突自我监控训练的实验研究

目的探索提高小学生同伴冲突应对能力的方法。方法采用2×2因素实验设计,运用自我监控的问题解决模式对106名三、五年级小学生(实验组)进行同伴冲突应对能力的训练,另101名三、五年级小学生为对照组,采用儿童社交问题解决访谈提纲和小学生社交技能教师评定量表于实验前后对两组学生施测。结果经过自我监控训练后,在解决冲突的有效性上,三年级实验组有显著提高(9.58±1.60/8.12±2.36,t=3.846,P<0.01),在解决冲突的适应性上,三、五年级实验组均有显著提高(10.52±1.87/7.96±2.44,t=6.612,P<0.01;11.02±1.65/7.54±2.44,t=9.561,P<0.01);教师评定的结果表明,训练后三、五年级实验组处理冲突的能力均有显著提高(29.35±1.70/26.62±4.66,t=4.063,P<0.01;31.59±2.73/27.59±4.39,t=6.147,P<0.01)。结论自我监控训练是一种有效提高小学生同伴冲突应对能力的方法。
