Conventional radiography using an AP view of the AC joint cannot be used to do a fine analysis of arthritic degeneration of this joint. It is likely that only CT scan or MRI is sufficient to analyse osteoarthritis in this joint. IV, basic science study. IV, basic science study. Certain structures and pathologies can be difficult to reveal under videoscopy alone during arthroscopic surgery. Ultrasound can be a useful contribution in arthroscopic diagnostic and therapeutic procedures. The main aim of the present study was to assess equivalence between endoscopic and external ultrasound for shoulder exploration. Secondary objectives comprised qualitative assessment of endoscopic ultrasound images and comparative assessment of acquisition time between the two techniques. An anatomic non-inferiority study was conducted on 6shoulders from 3subjects with a mean age of 84years. After ultrasound examination by a radiologist specializing in osteoarticular imaging, shoulder arthroscopy was performed by a single specialized surgeon, using an ultrasound endoscope. Number of visualized structures and image quality were assessed by independent observers. Ten of the 11structures of interest (91%) were visualizable on endoscopic ultrasound, versus 4 (36%) on external ultrasound (p<0.05). Mean endoscopic acquisition time was 9.5±6.3minutes [range, 5;22]. In the 11structures, image quality was better on endoscopic than external ultrasound, except for the acromioclavicular joint, where quality was better on external ultrasound, and the lateral side of the rotator cuff, where quality was equivalent. The present study demonstrated equivalence between endoscopic and external ultrasound for shoulder exploration. IV, Non-inferiority cadaver study. IV, Non-inferiority cadaver study. Scientific societies recommend to seek cancer prior to bariatric surgery. In our tertiary referral center, we aimed to study performance of abdominal CT-scan before bariatric surgery. We retrospectively included all patients who underwent bariatric surgery and a pre-operative abdominal CT-scan in our academic center, between January 2015 and December 2018. We included 521 patients (417 women and 104 men) with a mean age of 48.0±11.5 years. Mean preoperative body mass index was 44.9±7.0kg/m . Among the 392 patients with abnormal CT-scan, mean number of anomalies per patient was of 2.2±1.2. Vast majority of anomalies (91.8%) were non-significant. Only 5 (1%) patients needed treatment prior to bariatric surgery. No factor predictive of abnormal CT-scan was found. Only few patients had severe anomaly on CT-scan before bariatric surgery. Abdominal CT-scan could not be advocated to seek cancer before bariatric surgery. Only few patients had severe anomaly on CT-scan before bariatric surgery. Abdominal CT-scan could not be advocated to seek cancer before bariatric surgery. Complex human and system factors impact the effectiveness of Rapid Response Systems (RRS). Emergency Department (ED) specific RRS are relatively new and the factors associated with their effectiveness are largely unknown. This study describes the period prevalence of deterioration and characteristics of care for deteriorating patients in an Australia ED and examine relationships between system factors and escalation of care. A retrospective medical record audit of all patients presenting to an Australian ED in two weeks. Period prevalence of deterioration was 10.08% (n=269). Failure to escalate care occurred in nearly half (n=52, 47.3%) of the patients requiring a response (n=110). Appropriate escalation practices were associated with where the patient was being cared for (p=0.01), and the competence level of the person documenting deterioration (p=0.005). Intermediate competence level nurses were nine times more likely to escalate care than novices a
