Filter by:New type of imaging method is in demand clinically for early detection and treatment guiding of RA. Photoacoustic imaging (PAI), a hot spot in medical imaging society, which combines the merits of optical imaging and US and has a capacity in morphological, functional and molecular imaging, has shown potential in visualizing superficial organs, including small joints. The investigators developed a multi-modal photoacoustic/ultrasound (PA/US) imaging system, equipped with a handheld 3D PA/US probe, which wass able to provide 3D volume data of dual-wavelength PA imaging of small joints, in addition to real-time 2D PA/US imaging. The investigators plan to recruit RA patients in different disease conditions and healthy volunteers to receive the 2D and 3D PA/US examination on the 2nd and 3rd MCP, PIP joints and wrist joints using this imaging system, and to evaluate the potential clinical role of the imaging system in RA, and its added value to current imaging methods.
Effective analgesia after total abdominal hysterectomy is important for faster recovery and preventing complications which depend to pain. A multimodal and preventive approach is preferred to ensure adequate analgesia and to avoid side effects due to high doses of analgesics. The hypothesis was that the Quadratus Lumborum block (application of local anesthetics to the side of the abdomen) would be superior to Transversus Abdominis Plane block (application of local anesthetics in front of the abdomen) for analgesia before abdominal incision in total abdominal hysterectomy. The primary goal of the study was to evaluate the feasibility of ultrasound-guided Transversus Abdominis Plane block and Quadratus Lumborum block. The secondary goal was to evaluate postoperative adverse effects and patient satisfaction.
Introduction: Clinical ultrasound is a technique that increases diagnostic capacity and facilitates clinical decision making. The objective is to develop and validate an ultrasound training methodology oriented to the clinical practice of the family doctor. Methods: quasi-experimental study, with before / after design, with a control group and one year of follow-up. 20 family doctors working in primary care Health Centers and with a list of patients over 800 will be included and a control group of similar characteristics will be selected, in terms of age, gender and patient list. A structured training process oriented to the clinical practice of the family physician, Primary Care Clinical Ultrasound Classroom (AECAP) will be carried out, and the improvement of knowledge and skills will be evaluated, as well as the improvement of quality of care based on clinical indicators. Discussion: The Family Physician is in a privileged situation to increase the performance of the ultrasound in frequent clinical situations and allows a reduction of the attention times. Investigators hope that the results obtained in this study demonstrate the effectiveness of the structured training method (AECAP) and support the generalization of ultrasound in Primary Health Care.
The test subjects were selected from patients with clinical manifestations in muscle tone and healthy volunteers. Elbow flexor is the main target muscle. Fifty patients and 50 healthy subjects were given three assessment methods to measure muscle tension: modified Ashworth rating scale, elastic ultrasound technology and surface electromyography, and the data obtained by these three methods will be statistically analyzed and discussed.
448kilohertz capacitive resistive monopolar radiofrequency is a novel technique in physiotherapy and its usefulness and clinical relevance is still to be investigated at both clinical practice and also in performance. Current studies show promising results in different musculoskeletal disorders, however there no studies in the assessment of quality soft tissue in sporty population after the used of this technique.
The aim of this study is to compare the ultrasound-guidance versus auscultation to confirm optimal insertion depth of the cuffless oral Ring-Adair-Elwyn (RAE) endotracheal tube in pediatric patients undergoing general anesthesia.
Acne vulgaris is an inflammatory disease of the pilosebaceous unit, affecting about 85% of the young population. In the studies p. acne is a potent stimulator of the release of IFN-gamma (IFN-)) and IL-17 from CD4 + T cells, and the presence of IL-17 + cells in the perifollicular infiltrate has been shown in biopsies of inflammatory acne lesions. Therefore, acne is thought to be a Th17-related disease (1). This study was aimed to evaluate the presence of enthesitis in patients with acne vulgaris.
The purposes of this study is 1. To establish the validity of CEUS to measure renal perfusion by comparing it against ASL-MRI in young and older healthy volunteers, and generate a normative dataset of CEUS measures of renal perfusion. 2. Establish proof of principle for the use of CEUS to measure renal perfusion in the acute phase of AKI, demonstrating its feasibility and potential clinical utility. We will do this by performing daily CEUS measurements for up to five days in a cohort of people with AKI stage 3, commencing as close to onset. of AKI as possible, correlating with clinical data and following outcomes until 90 days.
Background: Ultrasound has become clinical skill widely used in most medical disciplines. Institutions are changing their curricula to implementing basic ultrasound knowledge, often supplementing traditional teaching with 'near-peer' tutoring through classes held by advanced peers. Near-peer tutoring has been found to be both effective and cost-effective. In Switzerland the most popular course in postgraduate training is a resource-intensive 21-hour basic course for abdominal ultrasound. However, this is expensive, and may not be the best way to impart these skills to undergraduates, who need training more adapted to their needs. Therefore a 21-hour blended-learning ultrasound course, comprising 5 hours of e-learning and 16 hours of near-peer tutoring has been developped. Students and their near-peer tutors autonomously organize individual practical teaching sessions within a 16 weeks time period. Methods: Medical students from second to fourth year at the Universities of Bern, Fribourg and Zurich will be included. Stratified by study site, students will be randomized to one of the two interventions. The blended-learning group will receive e-learning and near-peer tutoring over 16 weeks; the other group will receive 21 hours of teaching, from ultrasound experts, in a 2.5-day course. All participants will undergo a six-station OSCE directly after the course and 6 months later. Students will fill out online questionnaires at baseline, directly after the course and 6 months later. The mean scores of both groups will be compared at six months after the end of both courses. Secondary outcome measures will be students' ultrasound skills immediately after the courses, student satisfaction, multivariate regression exploring factors that affect outcome at 6 months and exploratory subgroup analysis. Discussion: This study is designed to compare the current way of ultrasound education in Switzerland with a new blended learning course. It aims to determine whether the blended learning course is as good as, or better than the existing 21-hour standard course. If this is found to be the case, blended learning could help to expand capacity to offer such courses to undergraduate medical students. It would eventually allow undergraduate Swiss medical students to acquire ultrasound skills before starting their residencies. This study also aims at improving the understanding of how to achieve effective student-centred learning supported by near-peer tutoring.
Objective: To determine the effectiveness of diaphragm visual biofeedback reeducation by ultrasonography in conjunction with high-intensity inspiratory muscle training versus isolated high-intensity inspiratory muscle training in athletes with lumbo-pelvic pain. Methods: A single blinded randomized clinical trial will be carried out. A total sample of 80 athletes with lumbo-pelvic pain will be recruited and randomized into 2 groups: one group will be treated by isolated high-intensity inspiratory muscle training during 8 weeks, and another group will be treated with diaphragm visual biofeedback reeducation by ultrasonography during 6 weeks in conjunction with high-intensity inspiratory muscle training during 8 weeks. Outcome measurements will be diaphragm muscle thickness evaluated by ultrasonography (main outcome measurement), pain intensity, pressure pain threshold, disability, quality of life and respiratory parameters by spirometry, which will be assessed before and after intervention.
