非言语型学习障碍儿童社会信息加工的特点

目的: 探讨非言语型学习障碍儿童社会信息加工特点.方法: 本研究为病例对照研究.根据确定学习障碍儿童的标准,先确定学习障碍儿童,然后对学习障碍儿童进行韦氏儿童智力测验,根据测验结果把学习障碍儿童进一步分为非言语型学习障碍组(23人)、言语型学习障碍组(28人),然后按1:1比例选取对照组(51人).设置儿童与同伴、成人相互作用的三类情景,每类情景又分为模糊和清晰两种情况,对三组儿童进行结构性访谈.结果: ①清晰权威情景下.非言语型学习障碍儿童的编码数显著低于对照组儿童[(2.35±1.15)vs.(3.25±1.27),P＜0.01];对人物意图的判断,非言语型学习障碍儿童选择"恶意"的比率(65%)高于言语型学习障碍儿童(29%)(P＜0.05);在工具效能感上,非言语型学习障碍儿童选择有效的比率(74%)高于言语型学习障碍儿童(36%)(P＜0.05).②非言语型学习障儿童在每个情景故事下的总反应数都显著低于对照组儿童[模糊同伴加入情景:(1.17±0.49)vs.(1.09±0.86).P＜0.01;清晰同伴加入情景:(1.09±0.28)vs.(1.69±0.96),P＜0.01;模糊同伴激惹情景:(1.09±0.41)V8.(1.49±0.78),P＜0.05;清晰同伴激惹情景:(1.17±0.49)vs.(1.65±0.95),P＜0.05:模糊权威情景:(0.96±0.36)vs.(1.37±0.72),P＜0.01;清晰权威情景:(1.00±0.30)vs.(1.37±0.59),P＜0.01].结论: ①清晰权威情景下,非言语型学习障碍儿童编码精确性不如对照组儿童;对他人意图的判断非言语型学习障碍儿童比言语型学习障碍儿童倾向于敌意归因;非言语型学习障碍儿童比言语型学习障碍儿童工具效能感高.②在每个情景下,非言语型学习障碍儿童比对照组儿童生成策略少,反应不灵活.     

A comparison between two emergency cricothyroidotomy instruments

As part of a training programme for younger doctors, two commercially available, emergency cricothyroidotomy sets were evaluated. Prior to the surgical procedure, half of the doctors in each group received an audiovisual lesson. In a simulated but realistic emergency situation, involving autopsy material, cricothyroidotomy was performed utilizing either the "Nutrake" or the "Gentofte" system. The audiovisual lesson increased the speed and the success rate of the doctors performing this procedure as well as strengthening their confidence. Both systems allowed positive pressure ventilation. The participating doctors achieved a higher success rate at a faster speed with the "Nutrake" set.     

Barriers of Adherence among Palestinian Healthcare Professionals towards the Protocol of Health Education and Counselling on Healthy Behaviours for Non-Communicable Diseases

BackgroundDespite the huge numbers of the universally produced and employed protocols, the adherence with them is still low to moderate in the healthcare settings. This study was employed to assess the attitudes of Palestinian healthcare professionals in Gaza Strip to health education and counseling on healthy behaviours protocol (WHO-PEN Protocol 2), for patients with non-communicable diseases in the Ministry of Health primary healthcare centers.MethodsThis cross-sectional study was conducted with a census sample of all governmental family physicians and nurses (n=175). The study questionnaire was developed based on Cabana theoretical framework. The Arabic version questionnaire was developed based on the cross-cultural adaptation framework. The psychometric properties of the Arabic version questionnaire was finally evaluated.ResultsThe psychometric properties of the Arabic version questionnaire showed good construct validity and internal consistency reliability. The overall adherence level to WHO-PEN Protocol 2 was 70.0, SD=6.9. The main perceived barriers were lack of incentive, patients'' factors, and lack of time. In general, most of healthcare professional respondents had a positive attitude toward the protocol, but this attitude was not predictor to protocol adherence.ConclusionThe good validity and reliability of the questionnaire can provide support for the accuracy of the study results. Varied implementation strategies targeting the major barriers derived from the study are extremely required for addressing the lack of incentives, patients'' factors and time constraints.     

基于塔巴模式的医院感染预防与控制课程设计研究——来自10所院校师生的数据分析

 目的 调查医院感染预防与控制课程设计中医学生的教育需求及教师的课程设计建议。方法 采用问卷调查全国5个地区10所医学院校师生的医院感染预防与控制教育需求和课程设计意见,参考塔巴目标模式课程设计步骤,论证课程设计方案。结果 584名学生中,仅11.8%(69名)的学生认为当前医院感染预防与控制教育能完全满足其需求,需求得分居前四位的为手卫生、消毒灭菌隔离、医院感染概论和职业防护。352名教师中,72.7%(256名)建议设必修课;86.4%(304名)选择总学时8~24学时,12.5%(44名)选择24学时以上,被调查教师建议10个章节学时平均总和为19.5;需重点掌握13项、熟悉9项知识和技能;86.4%(304名)教师建议理论与见习学时比为1 ∶0.5及以上;53.4%(188名)教师建议采取理论大课+小组见习(含技能操作)+线上学习的形式;63.7%(224名)教师建议师资团队由医院感染管理科+感染病科+护理部教师共同组成。结论 当前医学生的医院感染预防与控制教育远未完全满足需求,单独开课很有必要,建议设置16~24学时必修课,理论联系实践,多学科师资实施多元化教学,按照必修课考核。

How to perform high ultrasound examination of skin involvement among patients with systemic sclerosis – proposition of a unified protocol

IntroductionA fast and cheap method of skin assessment in systemic sclerosis (SSc) is an area of extensive research. Established in 1979, the Rodnan skin score is a palpation-based method used among clinicians. This method has some limitations, such as: examiner’s skills, subjective results, and no standardization. In the last few years researchers have been exploring ultrasound-based techniques as a possible tool for skin assessment among patients with SSc. The aim of the study is to develop a protocol of elastography-based skin imaging evaluation among patients with SSc.Material and methodsReview of the literature and own experience.ResultsProposition of elastography-based skin imaging protocol among patients with SSc.ConclusionsThe authors present a potential protocol of ultrasound-based examination of skin involvement among patients with SSc.     

The teaching of medicine at the University Centre for Health Sciences Yaounde,Cameroon: its concordance with the Edinburgh Declaration on Medical Education

Summary. The University Centre for Health Sciences (UCHS) or as it is referred to in French ‘Centre Universitaire des Sciences de la Santé’ (CUSS), became functional in 1969 with the enrolment of the first group of students. The objective of this training programme was to produce a scientifically sound, multipurpose doctor who would be fully operational in a rural setting with minimal equipment and supplies ( Monekosso 1970, 1972 ). The graduate had to be able to adapt readily to new situations and improvise whenever possible, calling for a high degree of competence and initiative. The training strategies adopted by UCHS in 1969 which met this requirement were later found to be in close concordance with the tenets of the World Conference on Medical Education held in Edinburgh in 1988, the Edinburgh Declaration. While some of the terminology may not have been worked out at the time, the programme developed embraced some new concepts hitherto untried or undeveloped:

• — the problem-solving approach in the first to the sixth year;
• — an integrated teaching approach during the first to sixth year of medical training;
• — an integrated medicine internship in district hospitals in the sixth year;
• — a community-based training approach throughout the training;
• — team training of three different health professionals;
• — competency-based training;
• — health services linked research;
• — health services linked training ( Monekosso & Quenum 1978 ).

The concordance of this programme to the Edinburgh Declaration is of great interest in realizing the World Federation for Medical Education programme and implementing the Edinburgh Declaration. The involvement of the three innovative medical schools in the planning stage of the curriculum explains this concordance.     

Challenges of and strategies for changing prescribing practices of health care providers

Problems related to inappropriate prescribing practices of physicians in general are well recognized. Dietary fluoride supplements have been implicated as one of the contributing factors in an increase in dental fluorosis. Inappropriate prescribing practices of providers have been cited as a major factor in this implication. Numerous studies of physicians and dentists have documented a lack of knowledge and inappropriate prescribing practices regarding fluoride supplements. The purpose of this paper is to identify barriers to changing fluoride-prescribing practices of health care providers and to suggest strategies for implementing change. To increase optimal and appropriate use of fluoride supplements, educational interventions are necessary for all user groups--detail men and women, physicians, dentists, pharmacists, nurse practitioners, dental hygienists, and the public. In addition, environmental supports for the educational activities in the form of policy, regulation, standards of care, and guidelines are recommended for consideration.
