Healthcare worker feedback on duodenoscope reprocessing workflow and ergonomics

BackgroundThe objectives of this survey study were to assess duodenoscope precleaning and manual cleaning times, identify human factors issues in duodenoscope reprocessing workflow or ergonomics, and ascertain any best practices in duodenoscope reprocessing.MethodsResearchers developed the confidential, qualitative, online Duodenoscope Reprocessing Workflow and Ergonomic Design Human Factors Survey with an intended audience of healthcare workers (HCWs) who routinely perform duodenoscope precleaning or manual cleaning. The unrestricted survey link was distributed to target HCW email addresses in December 2020; the survey closed in January 2021.ResultsThree hundred and forty-one individuals completed the survey. Most respondents complete duodenoscope precleaning in 10 minutes or less and manual cleaning in 16-to-30 minutes. Most respondents’ facilities use fixed distal endcap duodenoscopes. Most respondents experience pressure to work faster when cleaning duodenoscopes and reported that cleaning duodenoscopes caused fatigue or discomfort in at least one body part. Mentoring HCWs and retaining experienced staff were 2 primary duodenoscope reprocessing best practices identified by respondents.Discussion and ConclusionsTo enhance duodenoscope cleaning, facilities should provide ample reprocessing work spaces with incorporated height-adjustable work surfaces, train HCWs on validated duodenoscope reprocessing instructions, provide step-by-step instructions for HCWs when duodenoscope cleaning is performed, mentor reprocessing HCWs, and retain experienced staff.

18F-FDG PET/CT诊断肺恶性间叶瘤一例并文献复习

恶性间叶瘤（MM）是一种由2种或2种以上不同类型的恶性间叶成分组成的软组织肉瘤,其发病率较低。笔者报道了1例通过18F-FDG PET/CT检查发现的发生于肺内的特殊MM病例,分别从临床症状、实验室检查、影像学表现并结合相关文献报道分析了MM的特点,以加深临床医师对肺MM的认识。     

Clinical practice: intravenous thrombolysis in a patient with active cancer who experienced wake-up stroke

After reviewing the diagnosis and treatment process of a patient with active cancer who experienced wake-up stroke, we have summarized the clinical manifestations, laboratory examination results, imaging features, pathological results, and treatment in this report. Patients with active cancer who experience wake-up stroke often have mild neurological deficits at the time of onset. For the patient in this study, laboratory test results were mainly characterized by abnormal coagulation function and elevated tumor markers. The brain magnetic resonance imaging (MRI) images were characterized by involvement of both the arterial and venous systems. Thrombolytic therapy during the window period can improve the symptoms of neurological deficits. Overall, anticoagulation therapy was safe and effective in our patient.     

超声造影联合细针穿刺手感对甲状腺乳头状癌的诊断价值

 目的 探讨超声造影(contrast enhanced ultrasound, CEUS)和超声引导下细针穿刺细胞学检查(fine-needle aspiration cytology, FNAC,简称“穿刺手感”)及二者联合诊断甲状腺乳头状癌(papillary thyroid carcinoma ,PTC)的价值。方法 回顾性分析2017-09至2020-01解放军总医院海南医院超声诊断科进行超声检查、CEUS及超声引导下穿刺手感患者312例(312个结节),每个结节在穿刺过程中均记录穿刺手感,最终以手术病理结果为金标准。采用特征曲线(ROC)评价CEUS、穿刺手感和两者联合应用的诊断效果。结果 312例中共有良性结节116个,196个诊断为PTC。穿刺手感联合CEUS的准确率(97.450%)高于单独使用CEUS(87.244%)或穿刺手感(63.776%),差异有统计学意义(P<0.05)。CEUS和穿刺手感联合诊断甲状腺结节ROC曲线下面积(0.767)大于单独使用超声造影(0.734)及穿刺手感(0.711),差异均有统计学意义(P<0.05),但CEUS与穿刺手感在诊断PTC ROC曲线下面积差异无统计学意义。结论 CEUS联合穿刺手感对PTC诊断的准确性高于单一使用超声造影或穿刺手感。

颞下颌关节紊乱病的MRI评估

颞下颌关节紊乱病的常见表现包括关节盘移位及退变、关节腔积液、髁突及翼外肌异常改变。MRI软组织分辨率较高,成为目前颞下颌关节紊乱病诊断的金标准。了解颞下颌关节紊乱病的常见MRI表现对于口腔医师选择正确的临床治疗决策具有重要意义。     

单侧椎弓根钉联合对侧关节突螺钉内固定治疗下腰椎退行性疾病

目的探讨单侧椎弓根钉结合对侧椎板关节突螺钉固定在治疗下腰椎退行性疾病中的临床价值。方法回顾我院2011-06-2012-06年间收治的60例下腰椎退行性疾病患者,随机分为2组。30例观察组患者在微创系统下以椎弓根钉联合对侧的椎板关节突螺钉固定术对患者进行治疗;30例对照组患者以后路双侧弓根螺钉内固定术进行治疗。以Oswestry功能障碍指数(ODI)、疼痛视觉模拟评分(VAS)对两组的疗效进行对比;并对两组患者切口大小、手术用时、出血量、引流量、住院天数以及椎体稳定性、再手术率进行对比分析。结果术后1周,观察组患者VAS得分显著性高于对照组,P0.05,术后3、6个月,两组患者VAS和ODI评分无显著性差异,P0.05;观察组患者的切口大小、手术用时、出血量、引流量、住院天数等都显著性少于对照组患者,P0.05;两组患者的融合率比较无显著性差异;观察组患者椎体稳定性高于对照组,P0.05;观察组患者椎体再手术率低于对照组,P0.05。结论单侧椎弓根钉联合对侧椎板关节突螺钉内固定术临床操作简单、创部出血量少、稳定可靠、疗效确切,值得推广。
