皮质类固醇治疗外伤性视神经病变的四天关键时期(英文)

目的:评估静脉注射甲基强的松龙(IVMP)对外伤性视神经病变患者的疗效。方法:回顾性分析2000-01至2007-06我院收治的16例外伤性视神经病变(TON)患者的临床资料。1g甲基强的松龙分3d静脉应用,然后口服泼尼松龙11d,并逐渐减量。记录从损伤开始到治疗开始的时间。视力变化是本研究结果的主要功能评价指标。在入院时,治疗后1,2,3d;1wk和1mo时,分别记录最佳矫正视力(BCVA)。结果:共有16例患者纳入本研究,平均年龄为30岁,其中男性14例、女性2例。引起TON的主要原因有摩托车事故(占69%),打架斗殴(占19%)和体育运动(占12%)。所有患者都表现有相对传入性瞳孔障碍。在损伤后4d内开始静脉注射甲基强的松龙,采用Snellen视力表检查视力,绝大部分(56%)患者视力提高超过3行或大于等于0.5(6/12)。在损伤后5d以上才开始用类固醇治疗,视力则没有任何进步。结论:治疗TON,静脉注射中等到大剂量甲基强的松龙仍将起到重要作用。静脉注射甲基强的松龙治疗TON可能存在伤后4d的关键时期,超过了这个时期,该治疗可能就毫无效果。但还需要有更多的研究来为我们提供有明显统计学意义的数据。

Transthoracic approach in surgical management of Morgagni hernia.

OBJECTIVE: Morgagni hernia is an uncommon type of diaphragmatic hernias. Numerous approaches have been described and, particularly the significance of laparatomy has been emphasized as an operative technique. We present our experience on patients with Morgagni hernia operated on via transthoracic approach in our department. MATERIALS AND METHODS: Between January 1986 and March 2000, 16 patients with Morgagni hernia were operated in our department. Their ages ranged from 16 to 68 years (mean 51.5). Five (31.25%) patients were male, and 11 (68.75%) patients were female. Chest roentgenograms, thorax CT, barium enema roentgenographic studies were used as diagnostic utilities. Right posterolateral thoracotomy was performed in all patients. RESULTS: Hernia sac was present in all cases. Exploration revealed omentum in hernia sac in eight patients (50%), colon and omentum in seven patients (44%), only colon in one patient (%6). Postoperative course was uneventful. The mean follow-up was 5.7 years. There was no recurrence or symptoms related to the operation. CONCLUSIONS: We advocate transthoracic approach for surgical exposure as it provides wide exposure and easy repair of the hernia sac in Morgagni hernia.     

Valproate (depakine-chrono) in the acute treatment of outpatients with generalized anxiety disorder without psychiatric comorbidity: randomized, double-blind placebo-controlled study.

OBJECTIVE: Anxiety disorders are highly prevalent in population of European countries. However, the effect of Valproate (depakine-chrono) on generalized anxiety disorder (GAD) has not been studied in a double-blind placebo-controlled design. METHOD: Eighty patients (all men) were washout from the all medications. Each patient was randomized to receive either depakine-chrono (40 patients) for 6 weeks or matched placebo (40 patients) in a double-blind manner. Eligible participants, in addition to meeting the DSM-IV criteria for GAD and having a minimum score of 25 and more on the Hamilton Anxiety Scale, were required to be between 18 and 65 years. Response was defined as a 50% reduction in the Hamilton anxiety scale score. Response and side effects with depakine-chrono and placebo were compared by using analysis of variance (ANOVA) and chi-square tests. Six patients did not return for at least one subsequent assessment, leaving 74 patients (36 taking depakine-chrono and 38 taking placebo) in the valuables study group. RESULTS: Twenty six of the 36 depakine-chrono-treated participants responded by 6 weeks, versus six of the 38 placebo-treated participants (p<0.001). The most common and problematic side effect in the depakine-chrono group was dizziness and nausea. CONCLUSIONS: The authors believe this to be the first double-blind placebo-controlled randomization study to test the efficacy of a depakine-chrono in the management of anxiety disorders. They need to be replicated in a larger study group.     

Mass medical repatriation of injured civilians after terrorist attack in Mombassa, Kenya: medical needs, resources used, and lessons learned

INTRODUCTION: On 28 November 2002, three suicide bombers crashed their car into a hotel in Mombassa, Kenya; 12 people were killed, including three Israelis, and 80 were wounded (22 of whom were Israeli). The Israeli Defense Force Airborne Medical Evacuation Flight Teams participated in a repatriation mission to bring the wounded home. OBJECTIVES: The objectives of this study are to outline the distinctive aspects of this mission, as well as to share the experiences and lessons learned. METHODS: Israeli Army debriefing reports were used to study the composition of the crew, medical equipment taken, injury distribution, mode of operation, and mission schedule. RESULTS: A total of six fixed-wing aircraft were used--two Boeing 707s and four Hercules C-130s--with a total of 54 medical team members on board. A total of 260 Israelis were repatriated, 22 of whom were wounded, and three were dead. Of the casualties, 14 were conveyed sitting, and eight supine. The time from the first landing in Kenya to the evacuation of the last supine patient was 5.5 hours. Nurses, as well as social workers, played a central role in the mission. A forward team, including five doctors, was used for the initial organization and for gathering information on the medical status of the casualties. CONCLUSIONS: There was redundancy in the medical crew and medical equipment sent. The need for improved infrastructure on the medical aircraft was stressed. Based on this experience, a new mode for operation for similar missions in the future was formulated.     

Independent contributions of cortical gray matter atrophy and ventricle enlargement for predicting neuropsychological impairment in multiple sclerosis

The primary goal of this study was to investigate associations between regional gray matter (GM) atrophy and neuropsychological function in multiple sclerosis (MS), while accounting for the influence of central brain atrophy (i.e. third ventricle enlargement). Using a cross-sectional design, we studied 59 MS patients with brain MRI and neuropsychological testing. Regional gray matter fractions (rGMFs) were calculated from MRI images for 11 homologous brain areas using the semiautomatic brain region extraction (SABRE) technique. Neuropsychological testing followed consensus panel guidelines and included tests emphasizing episodic memory, working memory and processing speed. The analytic approach was stepwise linear regression, with forward selection and p<0.05 threshold for significance. Consistent with previous research, there were significant correlations between third ventricle width and neuropsychological tests. Stepwise linear regression analyses controlling for third ventricle width retained rGMFs obtained from specific regions within the prefrontal cortex. Left frontal atrophy was associated with tests emphasizing auditory/verbal memory. Right frontal atrophy was associated with impairment in visual episodic and working memory. For the first time, we show an independent relationship between cortical atrophy and cognitive impairment after accounting for the effects of central atrophy.

Israeli hospital preparedness for terrorism-related multiple casualty incidents: Can the surge capacity and injury severity distribution be better predicted?

Background

The incidence of large-scale urban attacks on civilian populations has significantly increased across the globe over the past decade. These incidents often result in Hospital Multiple Casualty Incidents (HMCI), which are very challenging to hospital teams.15 years ago the Emergency and Disaster Medicine Division in the Israeli Ministry of Health defined a key of 20 percent of each hospital's bed capacity as its readiness for multiple casualties. Half of those casualties are expected to require immediate medical treatment. This study was performed to evaluate the efficacy of the current readiness guidelines based on the epidemiology of encountered HMCIs.

Methods

A retrospective study of HMCIs was recorded in the Israeli Defense Force (IDF) home front command and the Israeli National Trauma Registry (ITR) between November 2000 and June 2003. An HMCI is defined by the Emergency and Disaster Medicine Division in the Israeli Ministry of Health as ≥10 casualties or ≥4 suffering from injuries with an ISS ≥ 16 arriving to a single hospital.

Results

The study includes a total of 32 attacks, resulting in 62 HMCIs and 1292 casualties. The mean number of arriving casualties to a single hospital was 20.8 ± 13.3 (range 4-56, median 16.5). In 95% of the HMCIs the casualty load was ≤52. Based on severity scores and ED discharges 1022 (79.2%) casualties did not necessitate immediate medical treatment.

Conclusion

Hospital preparedness can be better defined by a fixed number of casualties rather than a percentile of its bed capacity. Only 20% of the arriving casualties will require immediate medical treatment. Implementation of this concept may improve the utilisation of national emergency health resources both in the preparation phase and on real time.
