RESUMO
Arterial ischemic stroke is a rare but significant cause of neurological deficits in childhood. Even though there is a variety of risk factors, identifying the etiology can sometimes be a hard diagnostic challenge. Arteriopathies in general, and more specifically, arterial dissection is one of the uncommon pathologies that can cause incidents of pediatric stroke. We report a rare case of a young adolescent with posterior cerebral artery dissection after excessive consumption of caffeine, contained in energy drinks, only hours before the onset of neurological symptoms. A complete neuroimaging evaluation (MRI, intracranial US and digital subtraction angiography) at the admission and during the follow-ups supported the diagnosis of arterial dissection possibly caused by caffeine overconsumption.
RESUMO
We report the case of a 70-year-old woman who presented with an acute ischemic stroke involving the left frontal operculum secondary to an M2 dissection and a concomitant completely thrombosed aneurysm of the left distal middle cerebral artery. Initial imaging work-up was inconclusive due to the lack of typical radiographic features and only repeated imaging studies pointed towards the presence of an arterial dissection combined with a completely thrombosed aneurysm. The aneurysm was partially clipped and wrapped with excellent clinical result at 1-year follow-up. The clinical, imaging and therapeutic challenges of this rare entity are discussed.
RESUMO
OBJECTIVES: Minimally invasive interventional approaches are gaining wider acceptance with several specialities incorporating such principles. Awareness and understanding of interventional principles require efficacious education and training methodologies. We performed a systematic review to identify all available interventional speciality learning modules or training opportunities available for undergraduate medical students. We also propose a standardised framework for relevant modules. METHODS: We searched PubMed and all Ovid databases with no language restriction for studies that report and evaluate interventional speciality educational modules or similar training initiatives. We followed a prospective protocol (PROSPERO registration: CRD42018110006). Internal and external validity of the included studies was assessed. Qualitative synthesis of data was performed to define performance improvement and/or motivation towards a career in an interventional speciality. RESULTS: Out of 6081 records, 17 studies met the inclusion criteria, 15 of which were focused on interventional radiology. More than half of studies (9/17) were surveys where student knowledge and interest were reported as poor. 5 out of 6 studies which assessed the effect of educational interventions concluded to improved knowledge or performance. Most surveys concluded that early exposure can increase interest towards such specialities, improve knowledge and relevant motivation. CONCLUSIONS: Few studies report teaching initiatives in interventional radiology and other interventional specialities, reflecting the poor relevant motivation and knowledge amongst medical students. Simple interventions e.g. introductory lectures and simulation sessions spark interest in students and also improve knowledge as proven in the case of interventional radiology. Standardisation of such efforts via a suggested framework, Strategy Development Framework for Interventional Radiology, can further optimise such outcomes.
RESUMO
BACKGROUND: Essential Skills in the Management of Surgical Cases (ESMSC) is an international undergraduate surgical masterclass which combines ex vivo, dry lab and high fidelity in vivo simulation-based learning (SBL). It consists of 32 stations of skills-based learning, including open reduction internal fixation (ORIF) of fractures. Current literature suggests early involvement in skills-based learning at the undergraduate level is vital. AIMS: To compare students' dexterity and skills-based performance with demographic and educational background parameters. METHODS: 112 medical students from European Union countries including the United Kingdom, Germany, Greece, Cyprus, Germany, and Bulgaria were selected from a competitive pool of candidates to attend the course. Students undertook ORIF in an ex vivo swine model, and in a simulated fracture on a bamboo rod. Skills-based performance was assessed by two consultant surgeons with validated direct observation of procedural skills (DOPS) forms. Anxiety was self-assessed using the Westside Anxiety Scale prior to the ORIF stations. Dexterity was measured with the O'Connor tweezer dexterity test. RESULTS: Female students had significantly higher dexterity scores (median difference 7, p =.003). Right-handed students achieved higher dexterity than left-handed students (median difference 7, p =.043). There was no difference in students' performance across different medical schools, and across year groups (p <.05 for any correlation). Self-reported anxiety was not correlated with high fidelity skills-based performance (r = 0.032, p =.74). CONCLUSION: Anxiety does not seem to play a significant role in Simulation Skills-Based learning. Undergraduate surgical curricula should incorporate SBL-based modules to enhance practical skills learning and motivate future orthopedic surgeons.

BACKGROUND: The practice of evidence-based medicine and critical appraisal are essential for the modern doctor. Early engagement of medical students in research methodology is considered as a rising need for most medical school curricula; however, few peer-reviewed initiatives have been reported so far. We developed a Medical Education Research Group (eMERG) as part of a novel undergraduate surgical masterclass, which aimed to train undergraduate students on basic research methodology, as well as to motivate them to pursue a clinical and academic career in surgical specialties.Methods: eMERG consists of an international structured network of senior academics, consultant-level clinicians, senior and junior trainees who support undergraduate trainees. Students are selected from a competitive pool of applicants. Several small prospective studies in skills-based education, as well as systematic reviews on similar topics, have run under the umbrella of this framework, in the form of scholarship awards. Structured feedback questionnaires were distributed to evaluate the experience of the first three years. RESULTS: 12 students have participated in this pilot initiative. 11 manuscripts have been submitted for publication and 8 were accepted following peer-review in MEDLINE-indexed journals. Delegates perceived this experience as an excellent training opportunity which improved their research productivity. Delegates also stated engagement in research developed interest in the relevant surgical speciality, impacting their career aspirations. CONCLUSIONS: eMERG is one of the first reported European educational research networks for undergraduates. Research outcomes and students' perceptions conclude that eMERG enhances engagement with research methodology and motivation towards a career in surgery.
RESUMO
Essential Skills in the Management of Surgical Cases (ESMSC) is an international wet lab simulation course aimed at undergraduate students. It combines basic science workshops, case-based lectures and ex vivo skills modules, as well as in vivo dissections using a swine model. This study aims to evaluate the effectiveness of high-fidelity In Vivo Simulation-Based Learning for undergraduate level trainees. Also our goal was to compare the skill-based performance of final year students vs. more junior-level ones. Forty undergraduate delegates at clinical rotation level (male = 28, female = 12, mean age = 23.12, 22-24, SD = 0.69) attended this 2-day course in Athens. N = 1 (2.5 %) was year 3, N = 4 (10 %) were year 4, N = 23 (57.5 %) were year 5 and N = 12 (30 %) were year 6. N = 30 (75 %) came from Hellenic universities, N = 8 (20 %) from the UK and N = 2 (5 %) from Germany. N = 20 (50 %) attended the in vivo dissections module first, and then the ex vivo one (type A rotation), whereas N = 20 followed the reverse training sequence with the ex vivo dissection first, followed by the in vivo one (type B rotation). The mean global rating scores for type A rotation were better in both the in vivo by 0.10 (2.40 vs. 2.30) and ex vivo modules by 0.15 (2.85 vs. 2.70), though it did not reach statistical significance (p > 0.05). Furthermore, the mean improvement of performance, in the laparoscopic skills station for the type A rotation, was better compared to type B by 0.351 (2.00 vs. 1.65, p = 0.003). Year 6 students performed better in the laparoscopic station (2.00 vs. 1.75, p = 0.059), whereas years 3, 4 and 5 performed better in the in vivo (2.42 vs. 2.16, p = 0.157) as well as the ex vivo dissections (2.78 vs. 2.75, p = 0.832), though none of those comparisons reached statistical significance. Delegates seemed to appreciate and enjoy the in vivo dissections as reflected in the feedback (8.67/10, min = 6 and max = 10, SD = 1.79). Although medical students seem to appreciate in vivo dissections modules, currently, further evidence is needed to support their recommendation in the undergraduate level. Surgical skills should be part of the undergraduate curriculum to improve final year students' performance in the theatre.
RESUMO
BACKGROUND: Essentials Skills in the Management of Surgical Cases - ESMSC is an International Combined Applied Surgical Science and Wet Lab course addressed at the Undergraduate level. Laparoscopic Skills is a fundamental element of Surgical Education and various Simulation-Based Learning (SBL) models have been endorsed. This study aims to explore if there is any significant difference in delegates' performance depending on whether they completed In Vivo module prior to the equivalent in the laparoscopic simulator. MATERIALS AND METHODS: 37 Medical Students from various EU countries were divided in 2 groups, and both completed the "Fundamentals in Laparoscopic Surgery" module in the Dry-lab Laparoscopic Simulator as well as the same module "In Vivo" on a swine model. Group A (18 students, 48.6%) completed the "Fundamentals in Laparoscopic Surgery - FLS" module prior to the "In Vivo", whereas group B completed the "In Vivo" module first. Direct Observation of Procedural Skills (DOPS) were used to assess delegates' performance. RESULTS: The mean DOPS scores for the "FLS" and "In Vivo" models were 2.27 ± 0.902 and 2.03 ± 0.833, respectively, and the delegates' performance was not statistically significantly different between them (p = 0.128). There was no statistically significant difference in the scores among different gender, year of study, school and handedness groups. The alteration in the sequence between Dry-lab "FLS" and "In Vivo" modules did not affect the performance in neither the "FLS" nor the "In Vivo" models. CONCLUSIONS: The inexpensive, but low-fidelity "FLS" model could serve an equal alternative Simulation-Based Learning model for the early undergraduate training. Our study demonstrated that high fidelity In Vivo simulation for laparoscopic skills does not affect significantly the improvement in the delegates' performance at the undergraduate level. Further studies should be conducted to identify at which stage of training should high fidelity simulation be introduced.
RESUMO
BACKGROUND: Undergraduate Surgical Education is becoming an essential element in the training of the future generation of safe and efficient surgeons. Essential Skills in the Management of Surgical Cases (ESMSC), is an international, joint applied surgical science and simulation-based learning wet lab course. METHODS: We performed a review of the existing literature on the topic of undergraduate surgical education. Following that, we analyzed the feedback questionnaire received 480 from 2 recent series of ESMSC courses (May 2015, n = 49 and November 2015, n = 40), in order to evaluate European Union students' (UK, Germany, Greece) views on the ESMSC course, as well as on the undergraduate surgical education. Results Using a 10 point graded scale, the overall ESMSC concept was positively evaluated, with a mean score of 9.41 ± 0.72 (range: 8-10) and 8.94 ± 1.1 (range: 7-10). The majority of delegates from both series [9.86 ± 0.43 (range: 8-10) and 9.58 ± 0.91 (range: 6-10), respectively] believed that ESMSC should be incorporated in the undergraduate surgical curriculum. Comparison of responses from the UK to the Greek Medical Student, as well as the findings from the third and fourth year versus the fifth and sixth year Medical Students, revealed no statistically significant differences pertaining to any of the questions (p > 0.05). CONCLUSIONS: Current evidence in the literature supports the enhancement of surgical education through the systematic use of various modalities that provide Simulation-Based Training (SBT) hands-on experience, starting from the early undergraduate level. The findings of the present study are in agreement with these previous reports.

BACKGROUND: Essential Skills in the management of Surgical Cases - ESMSC is an International Combined Applied Surgical Science and Wet Lab course aimed at the undergraduate level. ESMSC combines interactive basic science workshops and case-based learning, with basic surgical training modules (BST) on Ex Vivo and In Vivo swine model. In Vivo Dissections include more advanced modules i.e. Abdominal Anatomy Dissections and Cardiac Transplant. AIM: To evaluate the educational environment of a novel course, as well as to compare Medical students' perceptions across various groups. MATERIALS AND METHODS: 83 Delegates from King's College London (KCL) and several Hellenic Medical Schools attended the ESMSC course. The DREEM inventory was distributed upon completion of the modules. RESULTS: The mean overall score for DREEM inventory was 148.05/200(99-196, SD = 17.90). Cronbach's Alpha value was 0.818, indicating good internal consistency of the data. Year 3/4 Students have a significantly positive "Perception of Learning", when compared to Year 5/6 (36.43 vs. 33.75, p = 0.017). KCL Students have a more positive view of the course compared to their Greek counterparts (155.19 vs. 145.62/200, p = 0.034). No statistical significant difference was noted when comparing male vs. female students (p > 0.05). CONCLUSIONS: Students seem to positively rate the ESMSC educational environment. Junior as well as KCL students appear to be more enthusiastic. Further research should focus on the optimal strategy for early involvement and motivation of various students' groups in BST.
RESUMO
PURPOSE: The integration of simulation-based learning (SBL) methods holds promise for improving the medical education system in Greece. The Applied Basic Clinical Seminar with Scenarios for Students (ABCS3) is a novel two-day SBL course that was designed by the Scientific Society of Hellenic Medical Students. The ABCS3 targeted undergraduate medical students and consisted of three core components: the case-based lectures, the ABCDE hands-on station, and the simulation-based clinical scenarios. The purpose of this study was to evaluate the general educational environment of the course, as well as the skills and knowledge acquired by the participants. METHODS: Two sets of questions were distributed to the participants: the Dundee Ready Educational Environment Measure (DREEM) questionnaire and an internally designed feedback questionnaire (InEv). A multiple-choice examination was also distributed prior to the course and following its completion. A total of 176 participants answered the DREEM questionnaire, 56 the InEv, and 60 the MCQs. RESULTS: The overall DREEM score was 144.61 (±28.05) out of 200. Delegates who participated in both the case-based lectures and the interactive scenarios core components scored higher than those who only completed the case-based lecture session (P=0.038). The mean overall feedback score was 4.12 (±0.56) out of 5. Students scored significantly higher on the post-test than on the pre-test (P<0.001). CONCLUSION: The ABCS3 was found to be an effective SBL program, as medical students reported positive opinions about their experiences and exhibited improvements in their clinical knowledge and skills.
