Reliability of Sonoelastography in Ductal Carcinoma

The objective of the study was to evaluate the reliability of sonoelastography in ductal carcinoma in patients in primary and secondary health care settings. Google Scholar, PubMed, Medline, Medscape, Wikipedia and NCBI were searched in January 2018 for all original research and review articles to identify relevant studies. Two reviewers selected the articles independently for based on the title and abstract. The selection criteria were sonoelastography accuracy for diagnosing ductal carcinoma as index text, B-mode sonography, and micropure imaging; surgery and histologic findings were used as reference text; and benign and malignant breast abnormalities and ductal carcinoma were used as target conditions. Two reviewers extracted the data on selected study characteristics, and the results were used to construct the tables and figures. Fifteen studies on ductal carcinoma were found. The overall sensitivity of sonoelastography in diagnosing ductal carcinoma was 85.7%, and the specificity, 79.8%. On the basis of the literature review, it was concluded that sonoelastography has high sensitivity and specificity in diagnosing ductal carcinoma.     

The management of emergency hospital visits for inflammatory bowel diseases: A French national expert consensus report

BackgroundManagement of inflammatory bowel diseases (IBD) in the emergency department is often suboptimal.AimsTo develop a national consensus checklist of indicators to facilitate decision-making in emergency departments concerning hospitalisation and referral for abdominopelvic computed tomography (CT).MethodsA Delphi survey was used to obtain consensus on a checklist of clinical and biological variables. 119 healthcare professionals experienced in treating IBD were invited to participate. Panellists were provided with a literature survey and invited to agree or disagree with items on a prototype checklist. Two successive rounds of voting were organised.ResultsThe prototype checklist included fifteen clinical or laboratory indicators for hospitalisation or CT. Four indicators were not retained in the Delphi process and four additional indicators added. The final indicators retained were: abdominal signs/symptoms of disease exacerbation, intravenous morphine titration, fever, vomiting, dehydration, recent intestinal surgery, ano-perineal abscess, bowel obstruction, haemodynamic instability, anaemia, acute kidney failure and elevated C-reactive protein. Consensus for the retained indicators was >88%.ConclusionsUse of this consensus checklist for the management of IBD in the emergency department may help improve standards of care and thus reduce the burden of these diseases.     

脂蛋白相关磷脂酶A2、胰岛素样生长因子-1与老年VD患者认知功能的关系及预测价值研究

目的 探讨脂蛋白相关磷脂酶A2（Lp-PLA2）、胰岛素样生长因子-1（IGF-1）与老年血管性痴呆（VD）患者认知功能的关系及预测价值。方法 选择2019 年3～6 月在我院接受治疗的VD 患者60 例为研究对象，同时选取同期在我院接受检查的健康者60 例为对照组，比较两组患者的Lp-PLA2、IGF-1、简易智力状态检查量表评分（MMSE）水平；采用Pearson 相关性分析法对Lp-PLA2、IGF-1 与MMSE 评分的相关性进行分析；采用受试者工作曲线（ROC）下面积（AUC）比较Lp-PLA2、IGF-1 对VD 的预测价值。结果 观察组患者的Lp-PLA2 水平明显高于对照组（P＜0.05），观察组患者的IGF-1、MMSE 评分明显低于对照组（P＜0.05）；Lp-PLA2 与MMSE 评分呈负相关性，IGF-1 与MMSE 评分呈正相关性；Lp-PLA2 与IGF-1 诊断VD 的AUC 值分别为0.940、0.954。结论Lp-PLA2 水平越低，IGF-1 水平越高，患者的认知功能越好，且Lp-PLA2、IGF-1 对老年VD 患者均具有较高的预测价值。     

Current status and challenges of Additive manufacturing in orthopaedics: An overview

Additive manufacturing is a rapidly emerging technology which is being successfully implemented in the various field of medicine as well as in orthopaedics, where it has applications in reducing cartilage defects and treatments of bones. The technology helps through systematic collection of information about the shape of the "defects" and precise fabrication of complex 3D constructs such as cartilage, heart valve, trachea, myocardial bone tissue and blood vessels. In this paper, a large number of the relevant research papers on the additive manufacturing and its application in medical specifically orthopaedics are identified through Scopus had been studied using Bibliometric analysis and application analysis is undertaken. The bibliometric analysis shows that there is an increasing trend in the research reports on additive manufacturing applications in the field of orthopaedics. Discussions are on using technological advancement like scanning techniques and various challenges of the orthopaedic being met by additive manufacturing technology. For patient-specific orthopaedic applications, these techniques incorporate clinical practice and use for effective planning. 3D printed models printed by this technology are accepted for orthopaedic surgery such as revision of lumbar discectomy, pelvic surgery and large scapular osteochondroma. The applications of additive manufacturing in orthopaedics will experience a rapid translation in future. An orthopaedic surgeon can convert need/idea into a reality by using computer-aided design (CAD) software, analysis software to facilitate the manufacturing. Thus, AM provides a comprehensive opportunity to manufacture orthopaedic implantable medical devices.

经CT测量成年人鼻腔、鼻窦部分骨性结构(附100例病例分析)

对100例慢性鼻窦炎患者的鼻窦CT片进行骨性结构测量,结果示前筛内外径0.79±0.06 cm,后筛内外径1.71±0.08 cm,筛板至鼻底部4.01±0.10 cm,筛顶至鼻底5.18±0.11 cm。该数据与经颅骨测得的数据近似,可以作为鼻窦手术的参考数据。100例慢性鼻窦炎患者中,各鼻腔发病率不等,鼻道窦口复合体发病率(91%)最高,认为与其解剖部位狭窄有关,提示临床医生通过阅CT片掌握鼻腔、鼻窦微细解剖结构的重要性。
