Background: To describe the mental health status of 78 child and adolescent survivors of post-war landmine ***: Child and adolescent survivors of landmine explosions who were younger than 18 years old at the time of the study were identified and enrolled in this study. The mental health status of the participants was assessed by general health assessment and psychiatric examinations. Psychiatric assessment and diagnosis were undertaken using the Diagnostic and Statistical Manual for mental disorders(DSM-IV) criteria. A psychiatrist visited and interviewed each survivor and identified psychiatric ***: Seventy-eight child and adolescent survivors with a mean age of 16.11±2 years old were identified and agreed to participate in the study. The mean age of the victims at the time of injury was 8.2±3.12 years old(range 2–15). Thirty-seven(47.4%) of the adolescent survivors suffered from at least one psychiatric disorder. Twenty-nine survivors(37.1%) were newly diagnosed and needed to start medication and psychiatric treatment. The most common findings were anxiety disorders(34.6%), including posttraumatic stress disorder(PTSD) in 20(25.6%), and generalized anxiety disorder(GAD) in 7(9%) subjects. Mild-Moderate depression was found in 5(6.4%) subjects. No personality disorders were observed, and two patients suffered from mental retardation. The study results revealed a significant association between age of casualty, duration of injury and limb amputation, and types of psychological ***: Child and adolescent survivors of landmine explosions had a high prevalence of psychiatric disorders.

背景：加巴喷丁是一种抗癫痫药物,可用于治疗急性疼痛和慢性神经病理性疼痛。本研究旨在观察术前单剂量口服加巴喷丁对术后疼痛及术中血流动力学改变的影响。方法：32例ASA Ⅰ-Ⅱ级拟在择期全麻下行腹式子宫切除术的患者,随机分为两组,加巴喷丁组术前2小时口服1200毫克加巴喷丁和术中输注0.3μg/kg/min瑞芬太尼;安慰剂组,术前2小时口服安慰剂胶囊和术中输注0.3μg/kg/min瑞芬太尼。临床相关的疼痛评估包括直接法和间接法。直接法包括用von Frey细丝在非优势臂于术前、术后24小时测试机械痛阈值,及术后24小时,测试切口周围痛觉敏感区域的机械痛阈值。间接法包括术后1,6,12和24h小时分别评估疼痛强度VAS值,记录术后首次需求镇痛药的时间和术后24h PCA的累积使用量。同时观察记录围手术期不同时间点血流动力学变量,如心率,收缩压,舒张压,平均动脉压。对两组患者的不良反应发生率也进行观察和评估。结果：与加巴喷丁组比较,安慰剂组术后首次需求镇痛药的时间明显较短,术后24h PCA的累积使用量较大。加巴喷丁组术后24小时归一化切口周痛觉敏感面积显著小于安慰剂组。术后24小时安慰剂组非优势臂机械痛阈值与术前相比显著降低。加巴喷丁组在喉及气管插管操作时的心率,收缩压,舒张压,平均动脉压波动明显减少。加巴喷丁组眩晕的发生率较明显,需予拟交感药物治疗的低血压发生率较高。结论：术前2小时顿服加巴喷丁1200mg可以有效的减少术后阿片类药物的用量、减轻术后疼痛,预防阿片类药物引起的痛觉过敏。加巴喷丁作为辅助用药,可以有效地减弱手术开始时喉部操作对血流动力学的影响。

Multiple pometacarpal （CMC） joints volar dislocations of car- are uncommon and have been reported rarely. A 25 years old male presented with injury to his left hand 6 days following a road traffic accident. Clini- cal examination revealed gross swelling of the hand and diffuse tenderness over the carpometacarpal area. His ra- diographs of the hand showed volar dislocation of the second, third and fourth CMC joints in association with anextra-articular fracture of the base of thumb metacarpal. He was treated by open reduction and percutaneous fixation using Kirschner wires. The functional results were excellent at one year follow-up.

A 24-year-old male was transferred to the emergency department while being in the state of quadriplegia with a history of performing Parkour sport, which is also called double front flip. Neurological examination revealed that the patient＇s muscle power was 0/5 at all extremities. The patient did not show any sense of light touch or pain in his extremities. In radiological studies, cervical spine X-ray and CT scan images showed C4-C5 subluxation with bilateral locked facets and spinal cord injury. The results of this very rare case study revealed that exercising Parkour sport without taking into account safety standards could result in irreversible injuries to the cervical spinal cord with fatal outcome.

本研究旨在研究自新冠大流行以来,酒店业的变化及游客的态度和期望的转变。本研究旨在监督新冠大流行以来,游客在旅行期间(态度,期望)与(预期价值,预知风险和酒店危机策略)之间的关系。基于计划行为理论和期望理论;这项研究将探究在新冠大流行之后,游客的期望和态度上出现的新变化,以期对大流行后的游客有更多的了解。此项分析的适用方法是定性研究,旨在分析和理解个人对特定社会或人类障碍的价值属性(Creswell,2014;Yin,2015)。定性研究的方法可以在了解像新冠肺炎这样的流行病,参与这些流行病的人以及有效的解决方案和策略方面起到核心作用。考虑到这项研究与游客表现出的特定行为有关,定性研究似乎更为相关,因为它被称为管理研究的一种适用的研究形式(Creswell,2014)。为此,基于对中东游客的采访样本,对他们大流行后对酒店住宿要求所做的改变进行研究。这些变化将对他们的旅行期望、需求产生哪些改变,并将其之前和之后的反应进行对比;在新冠大流行期间的风险、服务、政策及其个人态度变化。本文在NVivo12软件上对访谈进行了分析,以检验研究中提出的假设之间的关系。NVivo软件一直是世界上被引用最多的QDA软件,已被世界各地的公司和大学要求在定性研究中获得最准确的可视化数据。结果将显示游客是否受到新冠大流行的影响,并怎样改变了他们对酒店业的态度和期望。他们的决定取决于他们对风险的认识以及其他酒店利益相关者采取的预防措施。本研究丰富了计划行为理论和预期理论的文献。本研究将是一项衡量感知价值、感知风险和危机管理的研究,这些研究将衡量前一个依赖变量与态度和期望的关系。本研究有利于酒店业股东和旅游管理者了解旅游者及其新的需求、应对措施以及他们对大流行的期待,这将是旅游业复苏的最终途径。

Objective ： To analyze the data of patients with spinal cord injury （SCI） induced by road traffic crashes in southeastern Iran for better understanding the pattern of these injuries and therefore for better designing health system planning. Methods ： In this historical cohort study, the patients who had been transferred to Level I trauma center in southeastern Iran due to road traffic accidents with radiographic documented SCI were evaluated. Results： Among 64 patients with SCI, 38 patients （59.4 %, 36 males and 2 females, aged 27.42 years ± 9.44 years on average） were injured by road traffic accidents. Car and motorcycle accidents were responsible for 26 cases （68.4%） and 12 cases （31.6%）, respectively. And 31patients （81. 6%） had complete SCI. Conus medularis （T12-L2 ） was the most affected level. Conclusions： Results are discussed in terms of preventive measures, specifically those concerning the use of restraint and helmet and driving behavior. This study should be extended nationally to gain a larger case series so that the SCI risk of particular vehicle configurations, considering other crash factors, can be more precisely quantified and the characteristics for low occurrence of SCI can be more precisely identified.
