Fetoscopic photography

Fetoscopic visualization may be used for the prenatal diagnosis of external structural malformations of the fetus. Objective documentation of these fetoscopic findings would be desirable. The photographic equipment and techniques required for fetoscopic photography have been investigated, and the results of these investigations with standard fetoscopic instruments in current clinical usage are described. The factors evaluated include the light source, camera equipment, camera settings and film.     

Computerized Digital Imaging Techniques Provided by Digital X-ray Radiogrammetry as New Diagnostic Tool in Rheumatoid Arthritis

Purpose Our study evaluates digital x-ray radiogrammetry (DXR) and Radiogrammetry Kit (RK) as a new diagnostic method for the measurement of disease-related osteoporosis including quantification of joint space narrowing dependent on the severity of rheumatoid arthritis (RA). Materials and Methods A total of 172 unselected patients with RA underwent computerized measurements of bone mineral density (BMD) and metacarpal index (MCI) by DXR, as well as a semiautomated measurement of joint space distances at the metacarpal–phalangeal articulation (JSD-MCP 2–5), both were analyzed from plain radiographs of the nondominant hand. Results Correlations between DXR-BMD and DXR-MCI vs. parameters of RK were all significant (0.34 < R < 0.61; p < 0.01). An expected negative association was observed between RK parameters and the different scoring methods (−0.27 < R < −0.59). The maximum relative decrease in BMD vs. MCI as measured by DXR between the highest and lowest RA severity group was −27.7% vs. −27.5% (p < 0.01) for the modified Larsen Score, whereas the minimal value of relative DXR-BMD and DXR-MCI reduction could be documented for the Sharp Erosion Score (−20.8% vs. −26.8%; p < 0.01). The relative reduction of mean JSD-MCP using RK significantly varied from −25.0% (Sharp Erosion Score) to −41.2% (modified Larsen Score). In addition, an excellent reproducibility of DXR and RK could be verified. Conclusion DXR in combination with RK could be a promising, widely available diagnostic tool to supplement the different scoring methods of RA with quantitative data, allowing an earlier and improved diagnosis and more precision in determining disease progression.     

Digital subtraction angiography (DSA): New perspectives in angiography

Summary Digital subtraction angiography (DSA) has strongly influenced angiographic procedures. Because it is less invasive it has increased the total number of angiographies in all places where it was introduced. The paper gives an introduction to the procedure explaining the roles of digital and subtraction in DSA. It is written from a technical point of view. The examples are taken from and with the DVI system.     

数字医学技术在儿童腹部实质脏器损伤诊治中的临床应用效果

目的:探讨儿童腹部实质脏器损伤诊治中应用数字医学技术的效果。方法:选取2016年1月至2022年8月贵港市人民医院采用数字医学技术指导期间诊治的100例腹部实质脏器损伤患儿作为观察组,另选取2012年1月至2015年12月未采用数字医学技术指导期间诊治的100例腹部实质脏器损伤患儿作为对照组,比较两组患儿中,不同创伤类型患儿在保守治疗中的输血量、住院时间、保守治疗成功率;以及不同创伤类型的患儿中转手术治疗的术中出血量、手术时间及术后并发症情况。结果:选择保守治疗的患儿中,观察组肝损伤、脾损伤、肾损伤患儿的保守治疗成功率均高于对照组,输血量均少于对照组,住院时间均短于对照组,差异均具有统计学意义(P <0.05);中转手术治疗的患儿中,观察组肝损伤、脾损伤、肾损伤患儿的术中出血量均少于对照组,手术时间均短于对照组,差异均具有统计学意义(P <0.05);两组中不同创伤类型患儿的手术并发症发生率比较,差异均无统计学意义(P> 0.05)。结论:数字医学技术应用在儿童腹部实质脏器损伤诊治中,可为治疗方案的选择提供准确的指导,有助于提高治疗方案的效果,改善患儿临床指标,缩短住...     

Ischemic toe after surgery for lesser toe deformities: An algorithm

Ischemia after correction of lesser toe deformities is usually due to temporary vasospasm and can rarely cause gangrene. The published literature on dealing with the issue and been reviewed and used to suggest an algorithm for a logical step by step approach to a pale or white toe when encountered in the postoperative period.     

Digital health technologies for osteopaths and allied healthcare service providers: A scoping review

BackgroundDigital health technologies are poised to revolutionise the healthcare industry by improving accessibility to services and patient outcomes. The novel coronavirus disease-19 (COVID-19) pandemic has presented unprecedented challenges for the delivery of allied healthcare and has catalysed rapid adoption of telehealth. As such, allied healthcare consumers and providers stand to benefit from the capabilities of the digital health movement, ultimately justifying a scoping review of current and emerging technologies.ObjectiveTo provide decision makers with up-to-date information on the allied health applications of new and emerging digital health technologies; their evidence of efficacy, scope of use, and limitations.MethodsA scoping review of the literature was conducted, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. To synthesise original research, MEDLINE, CINAHL, and EMBASE databases were searched from 2010 to June 2020 and reference lists were examined for randomised control trials analysing the efficacy of these technologies in allied health applications.ResultsA total of 14 articles were included with a focus on common musculoskeletal conditions managed by allied health service providers. Studies were selected for data extraction after abstract and full-text screening by three independent reviewers. The results of this review indicate that telehealth technology effectively monitors and progresses patient care, while mobile health applications provide remote support and enable data collection.ConclusionEmerging trends suggest that digital technologies serve as promising adjuncts to allied healthcare. Further research is warranted regarding the safety and efficacy of digital health technologies in this context.

自适应算法与小波变换在心电信号滤波中的应用

心电信号是一种基本的人体生理信号,具有重要的临床诊断价值。然而,体表检测人体心电信号中常带有工频干扰、基线漂移、肌电干扰等各种噪声,给临床对心血管疾病的诊断带来了障碍。为了消除心电信号检测过程中带有的上述三种噪声,采用LM S自适应算法及小波变换理论,有针对性的设计了自适应滤波器、小波变换滤波器和自适应信号分离器等三种数字滤波器来滤除相应干扰。结果表明,对心电信号中存在的这三种噪声具有很好的滤波效果。
