Major incidents

A major incident is one that causes casualties on a scale beyond the usual capabilities of the emergency and healthcare services usual ability to manage. Major incident planning and rehearsal is vital to ensuring an appropriate response. Delivery of a major incident response requires command and co-ordination within and between emergency services, hospitals and specialist charitable organizations. Casualty management will require the set up of major incident infrastructure on scene to effectively extricate, triage, treat and transport casualties to appropriate facilities. There is a role for specialist doctors within the pre-hospital phase of managing a major incident, either within the ambulance command structure or operationally. Debrief and reviewing previous major incidents may identify individual, local and systemic factors that could be altered to improve the response to a future incident.

"11.24"海难援救军人的心理健康状况分析

目的 探讨海难后军队应激援救人员的心理健康特点，为建立特定人群的心理健康评定体系提供科学依据。方法 采用症状自评量表和自行编制的调查表对39名1999－11－24烟台“大禹”海难1mo后的善后援救军人进行了心理健康测试，并将调查结果与对照军人和国内军人常模进行了比较。结果 接受调查的应激人群的SCL－90总分79.5%（31／39）的人评定为正常，总分≥160分为8例，占20.5%。SCL－90总分、射体化、焦虑、恐怖与精神病性因子与国内军人常模比较无显差异，但阳性项目数、强迫症状、人际敏感、抑郁、敌对及偏执因子分均显低于国内军人常模（P＜0.05-0.01）；而阳性症状均分显高于国内军人常模（P＜0.05）。应激人群的阳性项目数明显低于对照人群，而阳性症状的痛苦水平明显高于对照人群（P＜0.01）；阳性症状均分仍显高于对照人群（P＜0.05）。结论 提示受调查的应激人群的阳性症状均分显高于国内军人常模，改善婚姻状况和与同胸关系、完善上级领导工作方法和善后处理可以改善SCL－90结果，减少生活事件的刺激量可望改善其心理健康状况。

移动医院的创建及其在国际救援中的应用

2004年底苏门答腊岛近海发生9级地震和人类历史上最严重的海啸,中国参加了国际救援活动.中国国际救援队创建了移动医院,在亚齐省班达亚齐市实施救援.移动医院的编制为26名医务人员,下分指挥组、分类检伤组、现场救治组、外科救治组、内科救治组、医技组、留观后送组.展开后占地约200平方米.开展了巡诊、院内救治、卫生防疫、灾后医院重建,及培训灾区当地医务人员等工作.总结出如下经验:应加强战役后方,应将所有信息数字化,培训复合型人才十分重要.移动医院是救援队实施救援的重要手段和有效方式,尤其在重大灾害中抢救危重伤员时可发挥重要作用.     

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.

Looking for resilience: Understanding the longitudinal trajectories of responses to stress

Taking advantage of two large, population-based, and longitudinal datasets collected after the 1999 floods in Mexico (n = 561) and the September 11, 2001 terrorist attacks in New York (n = 1267), we examined the notion that resilience may be best understood and measured as one member of a set of trajectories that may follow exposure to trauma or severe stress. We hypothesized that resistance, resilience, recovery, relapsing/remitting, delayed dysfunction, and chronic dysfunction trajectories were all possible in the aftermath of major disasters. Semi-parametric group-based modeling yielded the strongest evidence for resistance (no or mild and stable symptoms), resilience (initially moderate or severe symptoms followed by a sharp decrease), recovery (initially moderate or severe symptoms followed by a gradual decrease), and chronic dysfunction (moderate or severe and stable symptoms), as these trajectories were prevalent in both samples. Neither Mexico nor New York showed a relapsing/remitting trajectory, and only New York showed a delayed dysfunction trajectory. Understanding patterns of psychological distress over time may present opportunities for interventions that aim to increase resilience, and decrease more adverse trajectories, after mass traumatic events.     

Rescue ICSI of oocytes that failed to extrude the second polar body 6 h post-insemination in conventional IVF

BACKGROUND: Attempts to 'rescue' by ICSI oocytes that remained unfertilized 24 h after conventional IVF have generally resulted in poor outcomes. The aim of the present study was to compare the outcome of rescue ICSI performed on one group of patients 6 h after initial insemination with those of another group where rescue ICSI was performed 22 h after initial insemination. METHODS: Twenty-five patient IVF cycles provided the oocytes for rescue ICSI 6 h after initial insemination, and 20 cycles provided the oocytes for rescue ICSI 22 h after initial insemination in this retrospective study. Fertilization and cleavage rates, embryo quality, implantation, and pregnancy rates after rescue ICSI were the main outcome measures. RESULTS: A fertilization rate of 70.3% was achieved with 6 h rescue ICSI compared with 48.5% with 22 h rescue ICSI (P < 0.0001). From 6 h rescue ICSI, 12 clinical pregnancies (48.0%) resulted in three sets of twins, eight singletons and one abortion. From 22 h rescue ICSI there was one (5.0%) singleton pregnancy and delivery of a healthy baby. Likewise, the implantation rate was 20.2% from 6 h rescue ICSI compared with 1.72% from 22 h rescue ICSI (P < 0.02). CONCLUSIONS: Rescue ICSI after 6 h post-insemination (46 h post-HCG) gave better fertilization, pregnancy and implantation rates compared with rescue ICSI after 22 h when oocytes have become aged.

Acute optic neuritis: a virological study in relation to multiple sclerosis.

Previous ultrastructural examination of peripheral blood lymphocytes revealed the presence of intranuclear filamentous structures in multiple sclerosis (MS) and in some optic neuritis (ON) patients. The present investigation was undertaken in the attempt to correlate the presence of such structures with the etiology of ON and MS and possibly to demonstrate the viral origin of the filaments. Suitable virological and serological techniques were used to detect and isolate infectious agents from peripheral blood samples and body excretions of 12 monosymptomatic ON patients at their first acute attack. Nevertheless, any efforts to demonstrate the presence of a virus in these patients have been unsuccessful: no evidence of active viral infection was obtained by serological studies of serum and cerebrospinal fluid samples, nor could viral antigens or inclusions be observed by immunofluorescence and cytochemical analysis. Negative results were also obtained from studies performed in parallel on MS patients and various controls. The significance of the failure to isolate infectious agents from either ON and MS patients is discussed.
