Video recording surgical procedures is one of the most valuable tools for teaching and self-assessment in Dermatologic Surgery. A number of recording systems have been described in the literature. Nevertheless, they’re usually expensive (~500€) and time-consuming to prepare, the latter being a major disadvantage for a busy surgical speciality such as Dermatology. The authors describe a simple and inexpensive technique for surgical video capture in Dermatologic Surgery. For this setup, the surgeon needs only a smartphone with a camera (which is nowadays ubiquitous), a bike phone holder (10€ to 30€), an adjustable intravenous pole and, optionally, a powerbank. With the patient in position for the surgical intervention (seated or lying on his back on the surgical table, depending on the procedure), the bike phone holder should be attached to the vertically adjustable intravenous pole. The smartphone must be then set on the bike phone holder, with its “recording mode” already started. Optionally, a powerbank can also be attached to the intravenous pole to provide extra charge for longer procedures. The height of the intravenous pole, as well as its position and distance to the surgical table, should be adjusted accordingly before the intervention, in order to provide the best recording definition. The authors describe a simple, easy to setup, inexpensive system to record videos in Dermatologic Surgery.

ObjectiveIn field hockey, injuries are assessed by various recording techniques leading to a heterogenic collection of poorly comparable injury data.MethodsInjury data were prospectively collected at the 2016 Men’s Hockey Junior World Cup using the match injury reports (MIRs), video injury clips provided by the Fédération Internationale de Hockey, and daily medical reports (DMRs). A pilot study comparing injury type, mechanism, location on the field, injured body part and overall injury incidence among the different injury recording techniques was performed.ResultsMIRs and video injury clips were completely available for analysis. DMRs were returned from 11 out of 16 teams (69%). In total, MIRs yielded 28, video analysis 36, and DMRs 56 injuries. Overall injury rate varied between 24.8 and 57.9 injuries per 1000 player match hours. The majority of injuries affected the lower limbs by all three methods (41.7–61.2%) and were mainly caused by having been hit by the ball (20.4–50%) or stick (11.1–28.6%). Reports of concussions during competition were incoherent between MIR (2 cases) and DMR (no cases). The DMR was the only method to record overuse injuries (16.1%), injuries in training (12.5%), and time-loss injuries of one or two days (12.5%) or of three or more days (14.3%).ConclusionInjury data vary substantially between the MIR, DMR and injury video recording technique. Each recording technique revealed specific strengths and limitations. To further advance injury research in field hockey, the strengths of each recording technique should be brought together for a synergistic injury assessment model.

Traffic Delay

Traffic delay is one of the important aspects considered in the assessment of the operational performance of intersections. In the analysis of priority or unsignalised junctions, delays to minor road vehicles are often estimated using the existing mathematical models. However, the applicability of such a model depends on the basis and the source of the data with which the model was calibrated. This study was carried out to evaluate traffic delays to minor road vehicles at priority junctions in suburban areas. The data were collected at two priority junctions using video recording technique. The results showed that the day time delays were longer than of those observed during the twilight time. In both situations, delay to minor road vehicles increases as the volume of major road traffic increases. However, the effect of conflicting volume on the delay to the minor road vehicles is not clear. The comparisons between observed delay and the values predicted using the HCM and Tanner’s models indicated that, in general, the observed delays are much lower than the values predicted by both models particularly during the day time. Such a finding suggests that both HCM and Tanner’s models are not directly applicable to the analysis of delays at priority junctions in Malaysia.

Posterior Crossbite

14 children with unilateral posterior crossbites (PCB) participated in this study and 14 children with Angle's class I occlusion. Body posture analysis was made by a video recording technique. The results showed greater tilt in the angles of head tilt in PCB children when compared to neutral occlusion children. We also observed that head tilt followed the side of crossbite. Such results suggest that unilateral PCB could be related to the development of head tilt on the same side of the crossbite.

This study deals with the evaluation of traffic performance at the road network around the old city of Karbala from the southern side, at Al-Tarbia Street and Fatima Al-Zahraa Street, through the evaluation of intersections performance. This is followed by suggestions of some improvement proposals, which vary from changing timing plan, geometric improvement, to change intersection type completely. The study area composed of seven intersections, three intersections are four legs signalized, and the other four are roundabouts. The video recording technique is used to collect the traffic data for 27 approaches. These data are abstracted from video films using EVENT program, and processed by prepared EXCEL sheets. While, the spot speed data for each entire link in the network are collected using pavement marking method. SYNCHRO software was used for evaluation and analysis of signalized intersections, suggestion of best timing plan, and coordination. SIDRA INTERSECTION software was used for evaluation and analysis of both signalized intersections and roundabouts. The best proposal was also evaluated for the target year.

This article introduces a new approach of selective neural electrical stimulation of the upper limb nerves. Median and radial nerves of individuals with tetraplegia are stimulated via a multipolar cuff electrode to elicit movements of wrist and hand in acute conditions during a surgical intervention. Various configurations corresponding to various combinations of a 12-poles cuff electrode contacts are tested. Video recording and electromyographic (EMG) signals recorded via sterile surface electrodes are used to evaluate the selectivity of each stimulation configuration in terms of activated muscles. In this abstract we introduce the protocol and preliminary results will be presented during the conference.

Clip Occlusion

Abstract Basilar trunk aneurysms are historically associated with extremely high morbidity. The complexity of circumflex perforator arteries responsible for the perfusion of the brainstem makes surgical intervention for these lesions particularly challenging. This patient had a giant midbasilar aneurysm that encompassed multiple perforators but was associated with progressive mass effect and debilitating morbidity. Therefore, a transpetrous approach was used with transposition of the facial nerve and sacrifice of the vestibulocochlear nerve to permit access to the aneurysm. Hypothermic cardiac arrest was used to permit dome manipulation with a tandem fenestrated clipping of the aneurysm. Postoperative imaging demonstrated a reduction in mass effect attributable to the significantly reduced dome size and persistence of flow via a reconstructed basilar trunk. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.

Abstract Background Physicians generally have inaccurate self-assessment of their performance. One type of proposed intervention to improve this inaccuracy is the use of video-based feedback. The overall impact of this intervention on self-assessment accuracy in gastrointestinal endoscopy is unclear. Aims To systematically review current literature to determine if video-based interventions can effectively improve self-assessment accuracy in endoscopy. Methods We searched the following electronic databases from inception to 2019: Ovid MEDLINE; Ovid EMBASE, the Cochrane Register of Controlled Trials (CENTRAL); Education Resources Information Center (ERIC); Education Source on EBSCO; and Canadian Business Current Affairs EBM Reviews. Specifically, we searched for terms related to self-assessment, self-report, self-efficacy, video recording, and physician. Studies were included if they met the following criteria: physicians at any level of training and/or practice; studies that used an experimental design; compared self-rated assessments with external assessments of procedural skills in endoscopy; and at least one arm of the study involved a video-based intervention. Results Our search yielded 755 articles, of which 2 met all inclusion criteria. One study explored the use of three feedback interventions (practice only with no video; observation of their own video performance; observation of expert video performance) among general surgery residents performing flexible endoscopy, which found that only participants who watched expert video performances had improved accuracy of self-assessments. The other study investigated the use of three video interventions (video of own performance; video of expert performance; video of both own and expert performances) among novice endoscopists performing esophagoduodenoscopy (EGD), which found that the video of expert performance significantly improved self-assessment accuracy compared to the group with both videos. Conclusions The current data tentatively support the use of video review of expert performance to improve self-assessment accuracy in gastrointestinal endoscopy. A meta-analysis is planned to quantitatively assess the overall impact. Funding Agencies None
