目的 分析青岛市2018年1例输入性恶性疟的死亡原因,为预防疟疾死亡病例发生提供参考。方法 访谈接诊医生及患者家属,对患者病历和流行病学调查资料进行分析。结果 患者刘某,男,35岁,青岛市城阳区人,2018年3月19日到科特迪瓦务工,7月17日回国。25日患者到韩国办事,26日下午出现发冷、发热、出汗、头痛、浑身酸痛等症状,26—27日自服退烧药无好转,28日上午到韩国某医院就诊,未明确诊断,下午出现腹泻、呕吐症状,29日下午回国,14∶59到城阳区人民医院就诊,精神萎靡,经询问患者有非洲出国史可能患疟疾,16∶30将患者转诊至疟疾治疗定点医院,17∶50到达青岛市传染病医院时患者呈深昏迷状态,医生考虑患者病情危重且该院正在改建无ICU病房,建议转至有抢救条件的综合医院抢救。19:40患者转入海慈医疗集团ICU病房,21∶00被确诊为恶性疟,因病情危重,患者于30日14∶15死于多脏器功能衰竭。结论 对于输入性疟疾,根据流行病学史、临床症状和实验室检测结果尽早明确诊断,尽早使用抗疟药治疗,是避免出现死亡病例的关键。     

Does a high Mandard score really define a poor response to chemotherapy in oesophageal adenocarcinoma?

Background A high Mandard score implies a non-response to chemotherapy in oesophageal adenocarcinoma. However, some patients exhibit tumour volume reduction and a nodal response despite a high score. This study examines survival and recurrence patterns in these patients.Methods Clinicopathological factors were analysed using multivariable Cox regression assessing time to death and recurrence. Computed tomography-estimated tumour volume change was examined in a subgroup of consecutive patients.Results Five hundred and fifty-five patients were included. Median survival was 55 months (Mandard 1–3) and 21 months (Mandard 4 and 5). In the Mandard 4 and 5 group (332 patients), comparison between complete nodal responders and persistent nodal disease showed improved survival (90 vs 18 months), recurrence rates (locoregional 14.75 vs 28.74%, systemic 24.59 vs 48.42%) and circumferential resection margin positivity (22.95 vs 68.11%). Complete nodal response independently predicted improved survival (hazard ratio 0.34 (0.16–0.74). Post-chemotherapy tumour volume reduction was greater in patients with a complete nodal response (−16.3 vs −7.7 cm³, p = 0.033) with no significant difference between Mandard groups.Conclusion Patients with a complete nodal response to chemotherapy have significantly improved outcomes despite a poor Mandard score. High Mandard score does not correspond with a non-response to chemotherapy in all cases and patients with nodal downstaging may still benefit from adjuvant chemotherapy.Subject terms: Oesophageal cancer, Surgical oncology     

某设备所致脉冲X射线辐射场测量与防护评价

目的 了解某设备实验条件下不同位置脉冲X射线电离辐射水平，提出适当的防护建议。方法 采用热释光测量方法，分别在设备舱周围不同方向不同距离布放热释光剂量计，累积一定数量脉冲辐射后进行测量；采用电离室型X、γ剂量率仪（FJ-347A）实时测量工作状态下不同距离处电离辐射剂量率水平。依据《电离辐射防护与辐射源安全基本标准》（GB18871—2002）规定的职业照射人员和公众个人剂量限值提出不同工作位辐射防护建议。结果 热释光剂量计累计接收3 000个脉冲辐射，设备舱外壁0.01～8.98 mGy，顶部0.01～15.67 mGy，距外壁1～12 m之间0.01～2.18 mGy，工作位0 mGy。工作状态下，X射线剂量率仪测得距设备舱外侧壁1～20 m之间空气比释动能率范围0.26～16 mGy/h。结论 热释光剂量计、电离室型剂量率仪测量结果基本一致，说明两种方法均可用于脉冲X射线测量；工作状态下设备舱外近距离处辐射剂量率较高，可通过采取防护措施或者限制人员工作量以满足辐射防护要求。     

我国日间手术开展现状与前景展望

日间手术在国外已有上百年的发展历史，现已成为欧美国家重要手术模式。我国于20世纪初开始开展日间手术，但目前尚未普及，发展不平衡问题比较突出，存在认识不清、开展不规范、与医保支付对接不畅等问题。日间手术是一种使国家、医院和病人三方均受益的新型手术模式。近年来，国家相关管理部门积极引导，开展日间手术的医院明显增多，可以预见，我国日间手术即将进入快速发展的新阶段。因此，有条件的医院可以从简单、易操作的病种开始，落实临床路径，积累经验，再逐步稳妥展开。在保证质量的前提下，不断拓展日间手术范围，提高三、四级手术比例。同时，积极与医保支付政策对接，采取灵活的方式，获得医保的支持，更好地促进我国日间手术的快速发展。     

Investigating the Association Between Internet Health Information Use and Patient Willingness to Communicate with Health Care Providers

ABSTRACT

Communication between health professionals and patients is an intergroup phenomenon where the health professional has the most power and status. Over the past few decades, there has been a steady increase in the availability to patients of information about healthcare and specific diseases on the Internet. In this paper, we ask whether the use of Internet health information assists patients to manage their consultations with health professionals better and whether it alters the intergroup dynamic by providing a more equal status for patients. In this study 370 participants from Australia and Canada completed a survey that included a ‘willingness to communicate with health professionals’ scale. They also commented on their use and trust of Internet health information. Thematic analysis suggests that patients’ use of Internet health information serves as a broker between patients and their health provider in health consultations. We discuss the implications of these findings for health practitioners as they address how easier Internet access influences patient interactions with health professionals. We consider future research directions these finding provide in explaining communication behaviour in this context.

Identification of the medial femoral safe zone for drilling during dynamic hip screw side plate fixation: A CT angiogram tracing of the profunda femoris artery

Objectives

Iatrogenic injury of the Profunda Femoris Artery (PFA) at time of hip fixation surgery can increase morbidity and mortality and prolong the hospital stay. This is an injury that tends to pass unnoticed as a cause of postoperative deterioration despite being frequently reported in the literature. Our study aims to describe the anatomy of the PFA in relation to the medial femoral cortex with specific emphasis on its orientation relative to the position of a sliding hip screw side plate construct. By doing so we are able to present clear guidance to orthopaedic surgeons on how to avoid iatrogenic PFA injury at the time of hip fracture fixation.
