Fracture separation of the articular pillar of C5 following brass knuckles trauma

We report the case of a fracture separation of the articular pillar at the lower cervical spine. The trauma, following a brass knuckles, repeats almost in an experimental way the rotation and extension mechanism given in literature for the genesis of such injuries. From the admission in the orthopaedic service to the surgery, the development went in a characteristic way towards a rotatory displacement.

肺肿瘤99Tcm-N(NOEt)2SPECT显像与P-糖蛋白和增殖细胞核抗原表达的关系

目的探讨肺肿瘤99Tcm-氮-二(N-乙基-N-乙氧基二硫代氨基甲酸盐)[N(NOEt)2]SPECT显像病变部位与对侧对应正常肺组织放射性比值(T/N)与术后病理组织中P-糖蛋白(P-gp)和肿瘤增殖细胞核抗原(PCNA)表达间的关系.方法对22例(20例为术前未经药物治疗的肺癌,2例为肺良性病变)患者进行手术,取肿瘤标本,经常规石蜡切片,用免疫组织化学技术检测病变组织P-gp和PCNA表达,并与术前99Tcm-N(NOEt)2 SPECT显像T/N比值对比.结果22例患者中,20例肺恶性肿瘤99Tcm-N(NOEt)2 SPECT显像均表现为异常放射性浓聚,T/N比值为1.29±0.04;2例肺良性病变99Tcm-N(NOEt)2显像T/N比值为1.08±0.13,其中1例为假阳性.22例患者除1例肺腺癌仅P-gp表达阴性外,其余患者P-gp、PCNA均呈阳性表达.22例患者99Tcm-N(NOEt)2SPECT延迟显像T/N比值与术后病理组织中P-gp和PCNA表达程度均无关(r值分别为0.123和-0.145,P均＞0.05,双侧),且病理组织中P-gp与PCNA表达程度也无关(r=0.062,P＞0.05,双侧).结论肿瘤细胞摄取99Tcm-N(NOEt)2与其P-gp和PCNA表达程度无关.     

卵巢癌中蛋白激酶C的表达及其临床意义

Benefits of the DICOM Structured Report

Recently, the digital imaging and communications in medicine (DICOM) standard introduced rules for the encoding, transmission, and storage of the imaging diagnostic report. This medical document can be stored and communicated with the images in picture archiving and communication system (PACS). It is a structured document that contains text with links to other data such as images, waveforms, and spatial or temporal coordinates. Its structure, along with its wide use of coded information, enables the semantic understanding of the data that is essential for the Electronic Healthcare Record deployment. In this article, we present DICOM Structured Report (SR) and discuss its benefits. We show how SR enables efficient radiology workflow, improves patient care, optimizes reimbursement, and enhances the radiology ergonomic working conditions. As structured input significantly alters the interpretation process, understanding all its benefits is necessary to support the change.
