A follow‐up study of electromagnetic interference of cellular phones on electronic medical equipment in the emergency department

Objective: Considering the growing use of cellular phones and the fast appearance of new phone models, the electromagnetic interference of currently popular cellular phones on electronic medical equipment was tested. Methods: Three Personal Communication System cellular phones were put at different distances from multiple electronic medical devices, the interference effect was observed and the electromagnetic field strength measured with a spectrum analyser. Results: Only two small pieces of equipment, the CO₂ airway adapter and the haemoglucostix meter were affected and then only when the phone was in very close proximity. Conclusion: Compared to the results of our study in 1997 testing Global System for Mobile Communication phones, the Personal Communication System phones generated less electromagnetic interference. However a much larger scaled study and an accurate international electromagnetic interference standard are recommended before any change in the current restrictive hospital policy on mobile phone usage could be recommended.     

Developing a model for clinical and basic science teaching skills

This report describes a model for identifying sets of teaching abilities considered to be effective for medical school teaching staff, based on roles teachers assume and functions they are expected to perform as instructors. The specification of these teaching abilities was the first step in the development of a comprehensive course on Medical Instruction at the Basic Institute of Medical and Agricultural Biology of the State University of Sao Paulo, Botucatu, Brazil, where the senior author is employed. The work was based on the assumption that medical school teachers are expected to assume a variety of teaching roles and that identification and specification of the abilities that define their roles can result in more effective and efficient teaching.     

重视医学信用伦理的研究与开发

医疗行业市场化是必然趋势。在医疗行业市场化进程中，医学伦理道德除了道德价值之外，还含有积极的经济内涵。医学伦理道德也是重要的医疗资源，通过参与医疗市场资源的配制和运作，也可以产生经济效益，转化为医疗资本。医疗行业要重视医学伦理道德资源的开发。信用伦理是在市场经济条件下形成的，这是医学伦理学所面临的新课题。笔者认为，不说谎、不期诈，兑现承诺，保证医疗质量，发扬医学人道主义，是医学信用伦理的四项基本标准。     

狂犬病蛰伏数年后卷土重来的警示

[目的]警示各级政府务必重视和坚持“预防为主”的方针,采取有力措施,加强对犬类的管理,从根本上控制住“狂犬病”疫情。[方法]广泛地开展防治狂犬病健康教育,提高群众的防范意识和自我保护能力;加强部门协作,对犬只实行“管、免、灭、测”的综合性防疫措施;通过多渠道、多途径全面掌握犬伤人员的伤口处理与疫苗注射情况,对经济困难的犬伤者由政府报销疫苗费等措施保障犬伤人员得到及时处理。[结果]2005年犬伤人员伤口处置与疫苗注射率达99.67%;犬只免疫87320只,免疫率占58.21%;农村捕杀野犬、恶犬22408只、城镇限养区捕杀1189只;随机对3只家犬进行了带毒检测,带毒率达66.67%;2005年1～7月发病数10例,8～12月发病2例。[结论]政府重视,部门协作,措施具体,宣传到位,犬伤人员能及时得到正确处置是控制和降低狂犬病发病的关键。     

基于医疗伦理观的医疗质量成本计量与决策分析

医疗质量成本是建立在医疗伦理基础上的决策过程中或医疗服务决策时所必须考虑的一个重要因素。基于医疗伦理观的医疗信誉成本的正确计量及决策分析是医疗卫生机构提升医疗服务价值的关键所在。

女性减肥者的体像问题与社会支持及性格的关系

目的研究女性减肥者的体像特征及相关因素。方法采用体像障碍自评量表、社会支持量表、艾森克个性问卷调查了100例减肥门诊女性就诊者，并与100例近5年无减肥经历女性对照。结果(1)女性减肥者，体像得分明显高于正常对照组。(2)女性减肥者的体像得分与收入、P分、N分明显正相关；与社会支持得分明显负相关，与BMI无相关性。结论女性减肥者，不管是否为单纯性肥胖，都存在较多的体像问题，且与特定得人格和社会支持有关。     

Choice of general practice for postgraduate training among medical graduates and undergraduates in Nigeria

A questionnaire survey of career choices was carried out among 112 medical graduates, after one year's internship (group I), during their National Youth Corps programme in Kaduna, Lagos, Cross River and Oyo states of Nigeria, and 365 final-year medical undergraduates (group 2) in the colleges of medicine in the corresponding states. A total of 13% in group I and 40% in group 2 were undecided as regards their first choice. Obstetrics and gynaecology was the most popular first choice in both groups. General practice ranked fifth among group I, but displaced surgery to rank second among group 2. The differences were statistically significant. A total of 41% of group I and 46% of group 2 preferred to work in a teaching hospital, reflecting the high preference for surgical specialties. Twenty-six per cent and 33.7% of respondents in groups 1 and 2 respectively wished to own their own practice or work in the private sector. General practice is a new specialty and its growth is supported by a national postgraduate training programme. A shift towards general practice is seen compared with previous studies of career preference among Nigerian medical graduates and students. This may be due to a changing balance of supply and demand in the medical work-force, or a better assessment of the nation's health problems and manpower needs.     

小骨窗术和碎吸术治疗脑出血的临床应用研究

目的对比研究颅内血肿小骨窗清除术和颅内血肿(钻孔)碎吸清除术治疗脑出血的疗效。方法87例脑出血患者分为小骨窗组(行颅内血肿小骨窗清除术)、碎吸组(行颅内血肿碎吸清除术)和对照组(行内科保守治疗)。分别比较小骨窗组、碎吸组、保守组治疗前后的GCS评分及3组的GCS评分差。采用t检验、χ2检验和单因素方差分析比较。结果小骨窗组、碎吸组与保守组的GCS评分差比较均有差异(P<0.05);小骨窗组和碎吸组的GCS评分差比较也有差异(P<0.05)。结论小骨窗颅内血肿清除术、碎吸颅内血肿清除术、内科保守疗法在脑出血治疗中均能发挥一定的作用。小骨窗术和碎吸术在治疗中均能提高疗效、加快神经功能恢复,但小骨窗术较碎吸术能更好地发挥疗效、提高病人的生存质量。     

Evaluation of the legal risk of a ‘missed’ cancer in two breastscreen services

Variation in opinions of medical experts is a problem for both the legal and medical profession. This is particularly relevant in breast imaging. BreastScreen Queensland and New South Wales have developed a review protocol to assess ‘reasonableness’ of radiological opinions. It is hoped that the protocol will be acceptable to the courts and will result in a fair outcome for all parties involved in a medico-legal dispute.
