Post‐traumatic reactions among rescue personnel 96 hours after the Hilton Hotel bombing in Sinai: The effect of previous exposure

This paper considers the immediate post‐traumatic reactions of rescue personnel who were exposed to the Hilton Hotel bombing in Sinai. The entire rescue personnel (n = 26) were assessed and separated into two groups on the basis of previous exposure to the same type of trauma. The results suggest that among rescue personnel, those with previous exposure had a lower level of post‐traumatic symptoms than those who were being exposed for the first time. This supports the hypothesis that previous exposure to the same type of trauma has an immunizing effect for subsequent same type of traumatic event among rescue personnel.

基层公共卫生人员心身健康状况分析

目的了解基层公共卫生人员心身健康状况及影响因素,为提高其健康水平和工作质量提供科学依据。方法应用中国心身健康量表,采用分层整群抽样的方式,抽取胶州、嘉祥、兖州和邹城疾病预防控制中心及下属防保站的公共卫生人员584名进行问卷调查。结果基层公共卫生人员心身障碍发生率为39.43%,其中最高为骨骼系统14.17%,其次为神经系统12.73%;呼吸系统、心血管系统、焦虑、抑郁、精神病性5项因子评分小于全国常模;运用二分类Logistic逐步回归分析显示,从事本行业年限的增加是引起眼和耳疾病的危险性因素（OR=1.067）,职务的增高是导致心血管系统（OR=1.878）、消化系统（OR=1.675）、精神病性（OR=1.841）疾患的危险性因素;核心家庭（OR=0.136）、扩展家庭（OR=0.143）是降低抑郁发生的保护性因素。结论相关部门应采取综合措施,从工作和家庭环境等方面入手,提高基层公共卫生人员的心身健康水平。     

烟台口岸74例梅毒感染者检测结果分析

目的了解烟台口岸出入境人群梅毒感染的流行分布状况和趋势,确定重点监测对象,为口岸传染病监测和预防控制提供依据。方法对受检者血清样本采用甲苯胺红不加热血清试验（TRUST）和梅毒螺旋体抗体血凝实验法（TPPA）进行梅毒血清学检测。结果在检测对象中检出的74例梅毒感染者,梅毒感染率为0.20%,男女感染者无显著性差异（P〉0.05）,介于21-50岁的中青年感染者构成比为78.39%,入境人员梅毒感染率较往年显著增高。传播途径依然以性传播为主,临床表现不明显,感染以潜伏梅毒居多。结论做好传染病监测的同时,应积极做好性传播疾病的防治宣传工作和咨询工作,加强对远洋船员、劳务人员等高危人群的行为干预,做好入境人员的疾病监测和监管,提高出入境人员的防病意识,降低梅毒感染率。

Dynamic observations on NK cell activity and IL-2 and IFNγ productionin vitro in patients on maintenance hemodialysis

Summary In order to study the immune function of patients on maintenance hemodialysis (MHD), we assayed NK cell cytotoxicity against K⁵⁶² targets in 40 patients on MHD, and the production of IL-2 and IFN in peripheral blood mononuclear cells (PBMC) after PHA stimulation, in contrast to those in normal controls. The results showed that NK cell activity and IL-2 and IFN levels were markedly lower in the patients than in the controls. Afeter a single dialysis, NK cell activity as well as IL-2 and IFN levels were elevated to different extent. But there was no significant change in patients after long-term dialysis. There was a positive correlation between the NK cell activity and IL-2 and IFN activity in the controls, but no such correlation was found in the patients on MHD. There was a positive correlation between the NK cell activity and IL-2 activity in patients after dialysis, suggesting that immune function were impaired in the patients on MHD, with a decline in the activity of NK cell and IL-2 and IFN, and a disorder of immune regulation cycle. These abnormal immune impairments in the patients could be partly corrected by hemodialysis. However, long-term hemodialysis is not much helpful in the improvement of patient’s immune function.     

Teachers'' perceptions concerning the relative values of personal and clinical characteristics and their influence on the assignment of students'' clinical grades

Twenty senior teachers were asked to rank, in order of influence, the seven clinical and five personal characteristics used to grade third-year medicine clerks. Seventeen perceived themselves to be more influenced by clinical characteristics when assigning grades. Independently, the actual ratings completed over a 3-year period by these same teachers were analysed to measure the congruency between their perceived and actual grading behaviour. When actually rating students only nine raters were more influenced by clinical characteristics and just one half of the teachers displayed a congruency between their perceived and actual rating behaviour. The implications of these findings are discussed.     

Choosing a career in general practice: the influence of medical schools

Summary. This paper reviews the literature on career choice to investigate the undergraduate influences on the preference of Australian graduates for a career in general practice. Although isolation of influencing factors is difficult, admission criteria and undergraduate curricula may influence career preference. As the institutional environment of medical schools is weighted towards scientific research and specialized medicine, medical students may be socialized into choosing non-generalist careers. Medical schools should consider broadening selection criteria and curriculum exposure to produce graduates with a broad range of career interests.     

House officers in general medicine: their perception of educational value of rotation components

Summary: As curriculum planners in general medicine residency training programmes we were concerned about house officers' anecdotal reports that hospital work requirements often overshadow individual learning goals. After each of five rotations, we asked residents to identify the educational 'usefulness' of certain rotation components which can be included in three categories; team members, work-related activities and educational events. Of 165 surveys distributed, 127 (77%) were returned. Data were analysed by residency year and by all years combined. The mean overall perception of learning was 3.9 out of a possible 5 points suggesting that residents do find some learning value. Results suggest that different residency years vary as to the significance of specific educational components. The importance of faculty/resident relationships to residents' perceptions of learning value was highlighted in particular.

Students'' assessment of a course in obstetrics and gynaecology

A complete annual entry of 181 students were administered a questionnaire in which they were invited to make value judgements about all aspects of their 3-month course in obstetrics and gynaecology. The resulting performance indicators were used to compare individual staff and clinical firms.
