The proposed stabilizing mechanism of rotator cuff muscles is to limit excessive humeral head translation. However, an accurate measurement of glenohumeral joint translation in vivo has been challenging. We aimed to measure the effect of rotator cuff muscle contraction on glenohumeral joint translation using real time ultrasound (RTUS) and electromyography. Twenty healthy adults with no history of shoulder pathology were recruited. Six intramuscular electrodes were inserted in the rotator cuff muscles (supraspinatus, upper and lower infraspinatus, teres minor, upper and lower subscapularis)...

In 2012, following the Mediator(®) (benfluorex) scandal, France displayed the ambitious goal to implement a regulatory framework for controlling off-label drug use: the "Temporary Recommendations for Use" (RTUs). It aims to regulate the use of pharmaceuticals outside the scope of a marketing authorization (MA) by establishing a framework for patient monitoring and data collection. This is intended to ensure that the benefit/risk ratio is favorable for the indication approved by the RTU. The granting of an RTU enables the reimbursement of off-label drug use and encourages pharmaceutical companies to expand their MA...

Big data storage and processing are considered as one of the main applications for cloud computing systems. Furthermore, the development of the Internet of Things (IoT) paradigm has advanced the research on Machine to Machine (M2M) communications and enabled novel tele-monitoring architectures for E-Health applications. However, there is a need for converging current decentralized cloud systems, general software for processing big data and IoT systems. The purpose of this paper is to analyze existing components and methods of securely integrating big data processing with cloud M2M systems based on Remote Telemetry Units (RTUs) and to propose a converged E-Health architecture built on Exalead CloudView, a search based application...

Despite extensive use of immunohistochemistry (IHC) for decades, lack of standardization remains a major problem, even aggravated in the era of targeted therapy. Nordic Immunohistochemical Quality Control (NordiQC) is an international academic proficiency testing (PT) program established in 2003 primarily aimed at assessing the analytical phases of the laboratory IHC quality. About 700 laboratories from 80 countries are currently participating. More than 30,000 IHC slides have been evaluated during 2003-2015...

The close proximity of the infraspinatus to the teres minor and their functional similarity in producing external rotation of the glenohumeral joint make accurate insertion of electromyographic (EMG) electrodes into the teres minor difficult and questionable even when published guidelines are followed. The primary aim of this study was to examine the anatomical support for the current guidelines for inserting intramuscular EMG electrodes into the teres minor muscle. The secondary aim was to provide a technical description for ultrasound-guided electrode insertion into the teres minor...

OBJECTIVE: The placement of a peripherally inserted central catheter (PICC) routinely incorporates tip position confirmation using standard radiographs. In this study, we sought to determine whether real-time ultrasound (RTUS) could be used to place a PICC in a shorter time period, with fewer manipulations and fewer radiographs than the use of radiographs to determine accurate placement. STUDY DESIGN: This was a prospective, randomized, trial of infants who required PICC placement...

OBJECTIVE: Suprapubic aspiration (SPA) is the gold standard for obtaining uncontaminated urine specimens in young febrile children. The use of real-time ultrasound (RTUS) has been shown to increase the success rate of SPA. The BladderScan (BSUS) Verathon(®) is an alternative portable ultrasound device designed to provide automated measurement of bladder volume. Although simple and requiring minimal training, there are no data on the success rate of SPA using the device. METHODS: An audit of current SPA practice using BSUS in the ED of a tertiary referral children's hospital was conducted...

BACKGROUND: Worldwide ultrasound equipment accessibility is at an all-time high, as technology improves and costs decrease. Ensuring that patients benefit from more accurate resuscitation and diagnoses from a user-dependent technology, such as ultrasound, requires accurate examination, typically entailing significant training. Remote tele-mentored ultrasound (RTUS) examination is, however, a technique pioneered in space medicine that has increased applicability on earth. We, thus, sought to create and demonstrate a cost-minimal approach and system with potentially global applicability...

AIMS: Following surgical removal of the prostate, there may be compromise to the function of the pelvic floor muscles causing continence problems. Assessing the pelvic floor muscles of male patients can be an invasive process that causes discomfort, making it worthwhile to evaluate alternatives to the conventional method of Digital Rectal Examination (DRE). Real time ultrasound (RTUS) has been used with female patients as an alternative to internal assessments. This paper examines the reliability and validity of assessing the male pelvic floor using abdominal RTUS...
