多层螺旋CT对继发性附件扭转的综合评估

目的探讨继发性附件扭转的CT特征及其诊断效能,构建继发性附件扭转的评分系统。资料与方法收集经手术证实的伴有附件肿物的继发性附件扭转患者37例,以及伴有腹痛、附件肿物的对照组患者34例,分析继发性附件扭转的CT特征,采用受试者工作特征(ROC)曲线评价其诊断效能,构建继发性附件扭转的综合评分系统(AT-CI)。结果与对照组比较,继发性附件扭转以下CT特征发生率较高,包括肿物壁偏心性增厚(X^2=4.41,P<0.05)、附件出血(X^2=12.68,P<0.001)、肿物-子宫之间团块状结构(X^2=13.62,P<0.001)、旋涡征(X^2=10.71,P<0.05)、附件周围脂肪模糊/腹水(X^2=5.82,P<0.05)。其中肿物-子宫之间团块状结构敏感度及诊断价值最高,为81.1%(ROC曲线下面积0.71),旋涡征特异度最高,为91.2%。ATCI诊断效能优于任意单一CT特征(ROC曲线下面积0.83),评分0~2分继发性附件扭转可能性小,3~4分怀疑继发性附件扭转,评分>4分,则高度怀疑继发性附件扭转且特异度为100%。结论继发性附件扭转具有典型的CT特征,包括肿物壁偏心性增厚、附件出血、肿物-子宫之间团块状结构、旋涡征、肿物周围脂肪模糊/腹水。AT-CI是综合了继发性附件扭转全部CT特征的实用评分系统,提高了继发性附件扭转的诊断准确性。     

Clinical Study on CT-guided Modified Akupotomye in the Treatment of Lumbar Nerve Posterior Branch Compression

Objective: To observe the clinical effect of modified akupotomye closed lysis under CT guidance on compression of posterior lumbar nerve branch.Methods: Patients were diagnosed by HRCT 3-D reconstruction combined with clinical symptoms and signs.After HRCT three-dimensional reconstruction combined with clinical symptoms and signs, the patients were confirmed as posterior lumbar nerve compression.After CT accurate surface positioning, CT-guided modified akupotomye was used for closed lysis of the posterior lumbar nerve branch.Oswestry Dysfunction Index Questionnaire(ODI) was used for quantitative scoring, 7 days before and after treatment and 6 months after treatment.Results: In 62 cases, 20 cases were cured, with 25 cases markedly effective, 11 cases effective, and 36 cases ineffective.The total effective rate was 90.3%.ODI score: Self-paired t test 7 days before after treatment, P < 0.01;Before treatment and 6 months after treatment, self-paired t test(P < 0.01);Self-paired t-test was performed 7 days after treatment and 6 months after treatment(P > 0.05).Conclusion: With CT precise positioning, the modified akupotomye can be used to do closed lysis, to relieve the adhesion and compression, so that the low back pain can be relieved, with good clinical.The akupotomye closed lysis, combined with modern imaging technology has not only achieved good clinical effect, but also can improve the accuracy, safety and scientificity of akupotomye treatment.     

Epidemiologic Characteristics of Work-related Eye Injuries and Risk Factors Associated with Severe Eye Injuries: A Registry-based Multicentre Study

ABSTRACT

Purpose

Work-related eye injuries have been reported with a variety of epidemiologic and clinical characteristics. We aimed to identify epidemiologic characteristics of work-related eye injuries and risk factors associated with severe injury in a large metropolitan city.     

Etiologies of Acute Undifferentiated Fever and Clinical Prediction of Scrub Typhus in a Non-Tropical Endemic Area

Scrub typhus usually presents as acute undifferentiated fever. This cross-sectional study included adult patients presenting with acute undifferentiated fever defined as any febrile illness for ≤ 14 days without evidence of localized infection. Scrub typhus cases were defined by an antibody titer of a ≥ fourfold increase in paired sera, a ≥ 1:160 in a single serum using indirect immunofluorescence assay, or a positive result of the immunochromatographic test. Multiple regression analysis identified predictors associated with scrub typhus to develop a prediction rule. Of 250 cases with known etiology of acute undifferentiated fever, influenza (28.0%), hepatitis A (25.2%), and scrub typhus (16.4%) were major causes. A prediction rule for identifying suspected cases of scrub typhus consisted of age ≥ 65 years (two points), recent fieldwork/outdoor activities (one point), onset of illness during an outbreak period (two points), myalgia (one point), and eschar (two points). The c statistic was 0.977 (95% confidence interval = 0.960–0.994). At a cutoff value ≥ 4, the sensitivity and specificity were 92.7% (79.0–98.1%) and 90.9% (86.0–94.3%), respectively. Scrub typhus, the third leading cause of acute undifferentiated fever in our region, can be identified early using the prediction rule.     

青岛市2018年1例疟疾死亡病例分析

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。
