Abstract:
Background: Burnout syndrome (BOS) is caused both by psychological-emotional and physical stress. It is associated with decreased job performance and low career satisfaction. BOS has a significance influence both to physicians' performance in health care system, and in their private life. Until now, there was no data about this aspect of orthopaedic surgeon condition and health in our community. Aim: To assess the level of the burnout syndrome in orthopaedic surgeons and general practitioners (GPs), and the relations of their demographic features, job characteristics to the burnout syndrome Design: Questionnaire-based survey Methods: The sample consisted of 30 orthopaedic surgeons from the University Clinical Centre, and 40 GPs from the primary health care centres. The Burnout syndrome was measured by the Maslach Burnout Inventory (MBI). In addition to the MBI, the demographic data were collected and analyzed (age, age of practicing, gender, marital status) in relation to BOS. Results: Both groups expressed moderate to high rate of emotional exhaustion, depersonalization and low personal accomplishment. However, statistical significance between the groups had not been demonstrated. Neither gender nor years of practice or marital status did express statistically significant impact on the BOS items, i.e. they were not predictors of the BOS. Our results showed that about 70% of the physicians were emotionally exhausted considering both groups. On the other hand, orthopaedics demonstrated slightly higher depersonalisation level (55%) than GPs (38%). While GPs expressed lower personal accomplishment (48%) comparing to orthopaedics (29%). Discussion: The obtained MBI scores in this study were similar to those registered in US among residents, but when comparing to physicians in West Europe, which have similar health care system, our results demonstrated higher rates of BOS items. Conclusion: The Burnout syndrome represents an important problem for actively practicing physicians. The results of this and other similar studies should be used to evaluate medical training, practice, professional relations and introduce necessary changes.

Abstract:
The greater superficial petrosal nerve (GSPN) is an important but often underappreciated branch of the facial nerve. The GSPN is a mixed nerve which contains both sensory and parasympathetic fibers. It serves as the motor root of the pterygopalatine (sphenopalatine) ganglion. GSPN has a long course which passes across the middle skull base between the petrous bone and dura mater and running through the foramen lacerum. It then incorporates to the deep petrosal nerve and crosses along the pterygoid canal to the pterygopalatine ganglion. The postganglionic nerve fibers innervates the lacrimal glands, nasal mucosa and palatal mucosal glands via branches of the zygomatic nerve/zygomaticotemporal branch, sphenopalatine, greater palatine, lesser palatine nerves and pharyngeal nerve. Surgical anatomy of the GSPN nerve is often unfamiliar to many clinicians. As this nerve is usually unrecognized without use of high resolution microscope or endoscope, its anatomical knowledge is essential for surgeons basically otologists and other head and neck surgeon to minimize the risk of injury during surgical intervention. This review article surely increases the precise knowledge of the GSPN including its embryology, surgical anatomy, blood supply, relations with other structures and imaging.

Abstract:
We are going through a political, economic and social moment when human relations are fragmented. There is an attempt to impose wills that dominate economic power over disadvantaged people, as regularly shown. The leaders of the most powerful nations try to subdue those without economic assets, blocking people's free movement through land and sea blockages, and strengthening land confinements. While others always wait for some heroic attitude. In our activity as orthopaedic doctors, surgeons or managers we also face strong economic and financial impositions, "windows close but doors open." The speed of information in the current times will determine in the near future the quality of services that will be required, both for the ethical characterization of the information and for its credibility. Not long ago, the main complaint of ABTPé members was related to professional remuneration. We observed that the purposeful attitude of all associate members and the willingness of some members led to the beginning of change. We begin to consider the ethical views of payer and service provider, the legal aspects of adoptable attitudes, as well as the ethical attitudes of medical practice. Thus, these facts illustrate the strength and ability of fellow foot and ankle surgeons to take action that results in advantages for the entire class. These facts illustrate the strength and ability of foot and ankle surgeons to take action that results in advantages for the entire ABTPé. Making an analogy with the field of scientific culture we must also show how capable we are in producing useful scientific knowledge that benefits everyone. Creativity will be present with the release of new space for presentation of innovative procedures, through the technical notes in our publications. Discussions should be stimulated. The willingness of foot and ankle surgeon training centers to cultivate purposeful, ethical and socially comprehensive attitudes becomes extremely relevant. Thus, we will keep the flow of scientific development, improving our publications and projecting the potential of generating new knowledge compatible with our socioeconomic and cultural conditions. Our strength in producing publications capable of summing up the various currents of thought and our cultures will set our continent on a new level. In this edition we are considering the internationalization of knowledge. Yes, we are capable. Everyone's effort will be worth the award. Have a great reading. Jorge Mitsuo MizusakiEditor-in-Chief

Abstract:
L'objectif de ce travail est de mieux comprendre les différents mécanismes et les facteurs qui contrôlent la stabilité des produits congelés, au travers de l'étude de la mobilité (rotationnelle et translationnelle) de petites molécules dans des systèmes modèles (saccharose et saccharose + polysaccharide) cryo-concentrés. Les polysaccharides étudiés sont : le dextran avec différentes masses moléculaires (de 10 4 a 2 10 6 g/mol), la gomme arabique et le pullulane. Les milieux modèles ont été caractérisés d'un point de vue physico-chimique (viscosité, propriétés viscoélastiques et thermiques) afin de connaitre les paramètres susceptibles d'affecter la mobilité de petites molécules. L'effet de l'addition de 1 ou 10% de différents polysaccharides sur la diffusion rotationnelle (Drot) du tempol et la diffusion translationnelle (Dtrans) de la fluorescéine dans des matrices concentrées de saccharose (57,5%) a été déterminé respectivement par résonance paramagnétique électronique (RPE), et par les méthodes de recouvrement de fluorescence après photoblanchiment (FRAP) et de profil de concentration. La zone de température étudiée a été de 20 à 16°C. Dans ces conditions de concentration et température il n'y a pas de formation de glace. Un produit congelé a été également étudié, le jus de fraise, afin d'établir une relation entre l'état physique et la stabilité de ce produit. Finalement une réaction enzymatique (l'hydrolyse du DNPP par la phosphatase alcaline) et une réaction chimique (l'oxydation de l'acide ascorbique) ont été étudiées dans des milieux de saccharose et saccharose + dextran partiellement congelés.

Abstract:
AbstractIntroduction: The goal of this survey is to investigate the indications for preoperative digital subtraction angiography (DSA) before clipping of ruptured and unruptured intracranial aneurysms in an international panel of neurovascular specialists.Methods: An anonymous survey of 23 multiple-choice questions relating to indications for DSA before clipping of an intracranial aneurysm was distributed to the international panel of attendees of the European-Japanese Cerebrovascular Congress (EJCVC), which took place in Milan, Italy on 7–9 June 2018. The survey was collected during the same conference. Descriptive statistics were used to analyze the data.Results: A total of 93 surveys were distributed, and 67 (72%) completed surveys were returned by responders from 13 different countries. Eighty-five percent of all responders were neurosurgeons. For unruptured and ruptured middle cerebral artery (MCA) aneurysms without life-threatening hematoma, approximately 60% of responders perform surgery without preoperative DSA. For aneurysms in other locations than MCA, microsurgery is done without preoperative DSA in 68% of unruptured and in 73% of ruptured cases. In cases of ruptured MCA or ruptured non-MCA aneurysms with life-threatening hematoma, surgery is performed without DSA in 97% and 96% of patients, respectively. Factors which lead to preoperative DSA being performed were: aneurysmal shape (fusiform, dissecting), etiology (infectious), size (>25 mm), possible presence of perforators or efferent vessels arising from the aneurysm, intra-aneurysmal thrombus, previous treatment, location (posterior circulation and paraclinoid aneurysm) and flow-replacement bypass contemplated for final aneurysm treatment. These are all factors that qualify an aneurysm as a complex aneurysm.Conclusion: There is still a high variability in the surgeons’ preoperative workup regarding the indication for DSA before clipping of ruptured and unruptured intracranial aneurysms, except for ruptured aneurysms with life-threatening hematoma. There is a general consensus among cerebrovascular specialists that any angioanatomical feature indicating a complex aneurysm should lead to a more detailed workup including preoperative DSA.

Abstract:
Although research relating to the psychology of the cosmetic surgery patient is still in its infancy, there is a consensus among researchers that various combinations of psychological factors play a key role in the recent increase in demand for cosmetic surgery, in the motivation of prospective patients to undergo surgery, in their expectations of outcome, and in their postoperative adjustment. An appreciation of the psychological aspects of cosmetic surgery is therefore crucial and places the surgeon in a stronger position to evaluate a patient’s appropriateness for surgery. Indeed, appropriate patient selection is considered a vital part of a surgeon’s role in ensuring effective care and treatment. This chapter addresses why an understanding of psychological factors contributing to all stages of the treatment process is important to the provision of appropriate care and offers a framework for pre- and postoperative assessment.

Abstract:
Current standard surgical technique in patients undergoing coronary bypass grafting involves the use of an internal mammary artery (also known as an internal thoracic artery) bypass graft, in general to the left anterior descending coronary artery, and in many centres also the use of the right internal mammary artery to the right coronary artery. Several clinical studies have shown the superiority of mammary artery bypass grafts for survival of patients compared to the use of venous bypass grafts alone. Indeed, the internal mammary artery has several biological features, discussed in this chapter, that are remarkable and of great interest for biologists, cardiologists, and surgeons alike.

Proficient surgery requires good basic surgical skills and an understanding of the relevant anatomy. The time when a surgeon watched an operation, performed the same procedure, and then taught it has elapsed. Routine formulaic surgical procedures have become outdated and modern surgical practice is focused on individual patients and their specific needs. The main focus of surgery is now dedicated to the competent obtainment of skills and a complete understanding of human anatomy and its variations. This chapter focuses on the main anatomical structures encountered during gynaecological surgery. The anatomy of the pelvis in relation to the fetal skull is also covered.

Gender equity has been a topic of interest in medicine for decades; however, it has extended to include surgery, a field that has been dominated by men for centuries. Nowadays, gender inequity in surgery is a worldwide issue that needs to be addressed since significant disparities exist in the surgical field compared to the medical one. In this chapter, authors introduce the current status of Kuwait and the Gulf region regarding gender equality, and outline the history of women surgeons in the region. The evolution of medical education in surgery and the evolution of the healthcare system and how these relate to gender equity in surgical academia is presented. Challenges related to the uniqueness of the Arabic and the Islamic culture and the future directions of where the field of surgery is headed in relation to gender equity is discussed.

Abstract:
Rotational ankle injuries are one of the most common musculoskeletal problems treated by orthopaedic surgeons. The distal tibio-fibular syndesmosis may be disrupted during injury resulting in ankle instability. The goal of surgery is to restore anatomic relation of tibia, fibula, and talus. Any malreduction including that of the syndesmosis may result in poor clinical outcomes [1]. While currently accepted radiographic criteria can adequately detect tibio-fibular diasthesis or translation malreductions, it is not yet clear if the currently these criteria are equally suited for detection of rotational malreductions of the tibio-fibular syndesmosis [2]. The goal of this study is to quantify the sensitivity of fluoroscopic measurements of tibio-fibular overlap (TFO) and tibio-fibular clear space (TCS) to rotational malreductions of the syndesmosis. Standard x-ray imaging will be compared with a 3D fluoroscan which will simulate postoperative CT [3].

Abstract:
There is concern associated with the duration that a microsurgeon operates. Muscle fatigue can present itself over time and adversely affect the surgeon’s ability to perform appropriately during lengthy procedures. This paper explores a new method of analyzing muscle fatigue within the muscles predominantly used during micro-surgery. The captured Electro-MyoGraphic (EMG) data retrieved from these muscles are analyzed for any defining patterns relating to muscle fatigue. The analysis consists of dynamically embedding the EMG signals from a single muscle channel into an embedded matrix. The muscle fatigue is determined by defining its entropy characterized by the singular values of the Dynamical Embedded (DE) matrix. The paper compares this new method with the traditional method of using mean frequency shifts in EMG signal’s power spectral density. Linear regressions are fitted to the results from both methods, and the coefficient of variation of both their slope and point of intercept are determined. It is shown that the complexity method is more robust in that the coefficient of variation for the DE method has lower variability than the conventional method of mean frequency analysis.

Full text
Abstract:
Lower lumbar lordosis plays a critical role in sagittal alignment. It has been shown that restoration of lumbar lordosis in patients with preoperative sagittal imbalance is necessary to prevent postoperative sagittal decompensation [1]. Further, restoration of lower lumbar lordosis in patients with degenerative flatback syndrome has been shown clinically to result in additional correction of the thoracic curve and sacral slope [2]. Currently, there are three commonly used intraoperative techniques to restore lumbar lordosis: (1) cantilever bending, (2) in situ bending, and (3) compression and/or distraction of screws along posterior fusion rods. Although powerful, all three techniques require the surgeon to impart large forces to the accompanying posterior fusion hardware, often causing failure of hardware and inconsistency to achieve pre-operatively planned lordosis. To date, there has been no clinical or biomechanical study to address the comparative performance of these three techniques. In efforts to determine a standard of care for sagittal alignment via lumbar lordosis restoration, the goal of this study is to establish a relation between the three techniques, and the resulting demands on posterior fusion hardware. It is hypothesized that greater loads will be observed in the hardware during in situ bending, increasing the risk of pedicle screw pullout.

Abstract:
We have investigated beach stability against storm waves. The studies are done in relation to eroded beaches. We are testing a cobble-sand-gravel mixture as a means of using a soft method for coastal protection on nourished beaches. A physical model of an existing beach was built at scale 1:3. The cobble/sand grain size is in 1:3 scale while the gravel is 1:1.5 scale. The large scale experimental flume tests have been set-up in the new outdoor 120 m long flume in Québec city, Canada. The tests were conducted over two test seasons (2013–14). While we in the first test season studied impact on the beach due to incoming regular plunging breakers, the last season contained tests with incoming irregular plunging breakers on the beach with/without tidal variation. Herein, we primarily report on the wave impact due to irregular plunging breakers on constant and tidal varying water depths. The wave-tide interactions were conducted with a tidal range of 1 m in relation to beaches with steep beach slopes (1:10, 1:5, 1:1). The model inlet significant wave height was 1.1–1.5 m corresponding to equivalent prototype waves in the range of max. wave heights of 6–8.5 m with dominant periods of 12 s in water depth of about 15 m and tidal range of 3 m. In general, the Equilibrium Beach Profile (EBP) was reached after exposure to about 10,000 plunging breakers or the equivalent of five storms assuming each lasting 3 hours. A cobble berm was formed rapidly on the top of the beach, protecting the backshore against wave action and flooding while finer sediment was transported “offshore”. Beach width reduction was observed when the initial slope of the beach fill material exceeded the equilibrium beach slope. Sediment grain size sorting along the beach profile is discussed and compared to existing beach models, and EBP was compared to several EBP equations. From a coastal management perspective, in terms of durability, the mixed cobble-sand-gravel material is showing promise as a material to use for coastal protection. It is highly absorbent and the beach tends to maintain its shape over long time when exposed to several storms. However, storm surges in the combination with high tides can results in excessive run-up and potential flood risks. The stabilized beach typically had slopes of 1:7–1:9 independent of the initial slope. We found that irregular seas result in a less pronounced trough in the beach profile in the swash zone than incoming regular plunging breakers. The tidal interaction was further advantageous, naturally shifting the material back and forth. However, other materials and other sensitivity studies are necessary in order to provide firm conclusions about the usage of the cobble-gravel-sand mixture for coastal protection.

Abstract:
В береговой зоне отмечается проявление наиболее опасных природных катастрофических событий. Изучение этой зоны необходимо для более верного выбора оптимального пути ее развития. Очень ограниченное число исследований концентрируются на оценке опасности аномальных природных процессов. В данной работе была выполнена балльная оценка потенциальной опасности воздействия аномальных природных процессов на береговую зону островов Русский и Шкота. Для этого была проведена типология берегов островов Русский и Шкота. Всего на о. Русский выделено четыре типа и двенадцать подтипов берегов. На о. Шкота было выявлено четыре типа и восемь подтипов берегов. На обоих островах были определены коэффициенты расчлененности берегов. Этот показатель равен отношению между длиной берега и геодезической линии, соединяющей концы участка берега. Рассмотрены особенности воздействия опасных природных процессов (цунами, штормовых нагонов, оползней, обвалов, абразии) на побережье островов Русский и Шкота. На обоих островах эти процессы распространены в полной мере. Цунами подвержено в основном восточное побережье островов, штормовые нагоны развиты на всем протяжении берегов островов, а оползни и обвалы распространены достаточно дисперсно на обоих островах. Используя балльную систему оценки от 1 до 3, где 1 это наличие процесса (его слабое проявление), 2 среднее проявление, а 3 потенциальная опасность (для оползней и обвалов), были выявлены наиболее опасные типы и подтипы берегов островов. На о. Русский наиболее опасными подтипами берегов являются абразионноденудационные берега с обрывистым типом берегового уступа и узкими валунногалечными пляжами восточного побережья. На о. Шкота также наиболее опасными подтипами берегов являются абразионноденудационные берега с обрывистым типом берегового уступа и с узкими валунногалечными пляжами.The coastal zone researching is an important direction of geomorphology. In this zone is existed many hazardous natural processes. Coastal zone is a most important contact geosystem, where interacting different types of a nature use. In common, very important to investigate this zone for more correcting choice of optimal way of its solution. One of the main limited factors, that confine it are hazardous natural processes. Very limited number of scientists concentrates on hazardous anomalous natural processes estimation. It is revealed a scorecard method of potential hazard of natural processes influence on the Russky and Shkota coastal zone. It is given the coastal typology of Russky and Shkota islands. It is dedicated four coast types and twelve coast subtypes in Russky island. It is identified four coast types and eight coast subtypes in Shkota island. It is explicated a number of permeable intervals. This indicator is equal to relation between coastal length and geodesic line that connect both termination of a coast. Are examined special aspects of a hazardous natural processes influence (tsunami, storm surges, landslides, avalanches, abrasion) on Russky and Shkota Islands coast. These processes diffuse on both islands in full degree. Tsunami segregate on eastern islands coast, storm surges manifest on all stretch of islands coasts. Landslides and avalanches concentrate dispersily on both islands. By the use scorecard method from 1 to 3, where 1 is a process availability, but 3 is a potential hazard (for landslides and avalanches), it is revealed the most hazardous types and subtypes of islands coasts. The most hazardous subtypes of coasts for Russky Island are abrasion and denudation coasts with a steep type of coastal bench and narrow boulder and gravel beaches of eastern coast. The most hazardous subtypes of coasts for Shkota Island also are abrasion and denudation coasts with a steep type of coastal bench and narrow boulder and gravel beaches.

Abstract:
Pressure surges and fluid transients, such as steam and water hammer, are events that can occur unexpectedly in operating power plants causing significant damages. The steam hammer normally occurs when one or more valves suddenly close or open. In a power plant, the steam hammer could be an inevitable phenomenon during turbine trip, since valves (e.g., main steam valves) must be closed very quickly to protect the turbine from further damage. When a valve suddenly stops at a very short time, the flow pressure builds up at the valve, starting to create pressure waves along the pipe runs which travel between elbows. Furthermore, these pressure waves may cause large dynamic response on the pipeline and large loads on the pipe restraints. The response and vibrations on the pipeline depend on, one hand, on the pressure waves amplitudes and frequencies of the applied transient loads and on the other hand, on the natural frequencies and dynamic characteristics of the pipeline itself. The piping flexibility or rigidity of the pipeline (piping configuration plus support locations and types), determines how the pipeline will respond to these waves and eventually the magnitude of the loads on the pipe restraints. Consequently, the design of the piping system (pipe configuration and pipe support arrangement) is closely related to the dynamic amplification of applied steam hammer loads. This paper investigates how the pipe support arrangement and the flexibility of the pipeline relate to the dynamic amplification of the piping system due to steam hammer transient loads. The paper examines the correlation that exists, between the applied steam hammer transient spectrum and the pipe frequencies of the pipeline with the dynamic load amplification. Furthermore, it establishes the relation between the dynamic amplification of the pipeline and the pipe support configuration by examining various piping systems from very rigid (many supports) to very flexible (fewer supports). The typical pipe configuration of hot reheat line in a power plant is analyzed for steam hammer due to sudden valve closure (turbine trip) for six cases of closure time (50, 100, 200, 300, 400, 1600 ms). The transient loads on each pipe segment are generated using the PIPENET program and used as an input to CAESAR II stress analysis program to perform a dynamic time history analysis. The dynamic analysis is performed for a range of different pipe support arrangements, from very rigid to a very flexible. The magnitude of the restraint loads from the time history analysis, for each selected pipe support arrangement, is compared with the transient load spectrum associated. The analysis is performed using the PIPENET transient module and CAESAR II pipe stress analysis program, for a range of different pipe support arrangements, from very rigid to a very flexible. The results from the dynamic analysis are compared with the applied transient spectrum, and a dynamic load factor is established for the selected pipe support configuration. The dynamic load factor calculated based on the analysis results is compared with the factor proposed in standard industry practice. The information and the methodology presented in this paper aim to assist the design engineer in the power plant industry to select an optimum support arrangement that will cause the minimum dynamic amplification on the pipeline, thus reducing the steam hammer effects, the size and the cost of pipe supports.
