  1. Procedure Of Teaching Grammar Using Memory Enhancement

    Directory of Open Access Journals (Sweden)

    2011-11-01

    Full Text Available Teaching grammar has been regarded as a process of understanding from the context. It means a teacher teaches the pupils contextually more than just the rules. However, I have my own experience that teaching grammar methods must depend on the purposes of learning grammar. Some people learn grammar as a means to fulfill the syllabus needs for schools but other people learn grammar for special purposes out of school syllabus, such as for entrance test. For these reasons, the methods of teaching grammar should be different. The students who learn grammar based on the school syllabus probably needs longer procedure of learning that usually uses contextual teaching through listening, speaking, writing, and reading. Nevertheless, students who learn grammar for test need shorter procedure of learning such as memorizing. Therefore, I propose giving a workshop of teaching grammar using memory enhancement as another alternative teaching grammar method. This workshop would show the class that grammar can be learnt through memory enhancement process, i.e.; mind map, music, memory technique and drill to boost up students understanding for test preparation.

    Full Text Available Writing as one of language skill is often considered very difficult. It is due to the fact that writing needs to produce and organize ideas using appropriate vocabulary, language use, paragraph organization, and mechanism. It also needs to turn the ideas into a readable text and for foreign language learners, they should also transfer ideas from their native language into target language (foreign language. It raises any problems for them to create a good text. Moreover, the situation in the class does not always supportthem in which the techniques of the teacher in teaching writing is boring and monotonous, do not give enough attention to help students explore their writing skills. So that they attend the writing class only for procedural formality.Thus, it is considered important to elaborate various techniques to build nice classroom atmosphere as well as to improve students’ writing skills.

    2013-10-01

    Many key medical procedures are performed every day in clinical practice to yield important diagnostic information and to help determine the disease response to intensive treatments. Training clinicians to perform procedures competently and confidently thus carries considerable weight, helping to assure patient safety, the obtainment of adequate samples and minimising patient discomfort. This article considers how Robert Gagne's instructional design model may be effectively used to design lesson plans and teach procedural skills in small group settings. Gagne's model is based upon the information-processing model of mental events that occur when adults are presented with various stimuli. It highlights nine specific instructional events, which correlate with crucial conditions of learning, and are arranged to maximally enhance the learning process, improve session flow and, ultimately, ensure lesson objectives are comprehensively addressed. This article uses the nine points described by Gagne to outline a comprehensive lesson guide for teaching psychomotor skills, using a bone-marrow aspirate procedure as an example. Each of Gagne's instructional events is considered with specific activities for each, and with the variety of activities delineated to meet diverse learning styles. Gagne's instructional events can produce an effective and comprehensive lesson plan for teaching procedural skills, preparing learners with various preferred learning styles to perform psychomotor skills competently in clinical practice. This lesson plan can be of use for both teachers and students across clinical specialties, encouragingly outlining how Gagne's systematic and widely referenced theory can be creatively and practically used. © 2013 John Wiley & Sons Ltd.

    2012-03-01

    To identify sucessful teaching techniques in the operating room environment through examining the teaching of the midurethral sling (MUS) surgery. The authors distributed questionnaires with open-ended questions about teaching and learning MUS to 5 urogynecology attendings and 16 obstetrics-gynecology residents in spring 2010. In an effort to identify qualities of an effective sling teacher, the authors used grounded theory to determine common themes and to code participant responses for examples. Of 21 potential respondents, 14 (67%) returned questionnaires. The authors analyzed these and identified seven commonalities among effective sling teachers: they (1) emphasize anatomical landmarks (as determined by 64 total comments); (2) use perceptual-motor teaching (PMT; 38 comments); (3) encourage repetition (28); (4) promote early independence (34); (5) demonstrate confident competence (23); (6) maintain a calm demeanor in the operating room (20); and (7) exhibit a willingness to accept responsibility for mistakes and consequences (9). The second-most common attribute, using PMT, requires the teaching attending to emphasize the motor and tactile aspects of operating and involves incorporating not only what learners see but also what they feel. The authors report seven qualities or techniques fundamental to good teaching practice in a high-stress, high-technology surgical environment, and they have identified the use of PMT, which to their knowledge has not been previously described. Teachers and learners in this study characterized PMT, which is likely generalizable to surgical procedures other than the MUS, as important. Future research should focus on exploring this technique in other surgeries.

    2014-11-01

    Full Text Available Summary: The Nuss procedure is a prevalent minimally invasive surgery for pectus excavatum. Although the Nuss procedure has the advantage of leaving less obtrusive scars, the standard technique requires at least 3 skin incisions to insert several instruments. We experienced 7 cases of the modified Nuss procedure using a single incision during a 7-year period. To facilitate passing of the bar, a traction guide was created according to our unique method. There was no need for a bar stabilizer, and no severe intraoperative complications occurred. All patients exhibited satisfactory short-term results; however, 1 patient suffered from bar rotation and required repeat surgery for fixation. Two patients underwent bar removal via the same single incision without any difficulties.

  15. Methods for teaching effective patient communication techniques to radiography students.

    Science.gov (United States)

    Makely, S

    1990-07-01

    Teaching students to communicate effectively with patients has always been part of the radiography curriculum in the USA. However, developing these skills has become even more important in recent times due to several factors. Patients who have been well versed in what to expect from the examination being conducted are in a better position to co-operate with the radiographer. This increases the chances of producing optimal results from an examination at the first attempt, thus reducing radiation exposure, patient discomfort and the overall cost of conducting the procedure. Also, increased competition among health care providers has resulted in more emphasis being placed on patient, or customer, satisfaction. Radiographers are in the 'front line' of patient care. Patients often have more interaction with radiographers than with physicians or other medical specialists. Radiographers who practise effective communication techniques with their patients can alleviate anxiety and make an important contribution to the overall satisfaction of the patient with respect to the quality of service and care they receive. This article describes instructional methods being used in the USA to help develop effective patient communication techniques, and reports the findings of a study among radiography educators as to which of these methods are thought to be most successful.

  16. An experimental analysis of some procedures to teach priming and reinforcement skills to preschool teachers.

    Thomson, C L; Holmberg, M C; Baer, D M

    1978-01-01

    This Monograph reports the results of teaching preschool teachers to be successful at increasing desired behaviors of their children, thus becoming successful teachers. Five teacher-training techniques were examined experimentally under single-subject designs: written assignments, feedback from viewing graphs, on-the-spot feedback from a wireless radio (Bug-in-the-Ear), feedback from an observer, and self-counting. Those teaching procedures that included prompt and frequent information to the teacher about the behavior under study were the most effective techniques. Self-counting, in which the teacher tallied the number of times she emitted the behavior of either priming or reinforcing social or verbal behavior of a child (or children), and observer feedback, in which the observer reported to the teacher periodically during the hour the frequency of her behavior, were the most reliable teaching techniques. The other procedures, while less reliable than self-counting and observer feedback, were effective with some teachers. Maintenance of teacher behavior across settings was examined with a group of Head Start teachers, and maintenance of teacher behaviors across different child behaviors and different children was examined with three student teachers. The results indicated that teaching was more likely to maintain if it occurred in the teacher's home setting rather than at another site. In all cases, when generalization occurred across settings, time, or children, the frequency of the teacher's behavior was not as high as when the relevant behavior had been trained directly. Results supported the proposal that it is possible to define effective teacher behavior, not just characterize it, as it occurs in the classroom, and that effectiveness can be measured by defining and observing the child behaviors to which teacher behaviors are directed.

    2014-06-01

    Full Text Available This paper presents an analysis of the practical implementation of two teaching techniques so-called Problem-Based Learning and Cooperative Learning. These techniques were applied to some courses in the Department of Mechanical and Electrical Engineering and evaluated through assessment rubrics. In a sample of students and teachers, the assessment rubrics were applied to numerically evaluate the proportion of each course, in which the teacher uses traditional teaching versus teaching for meaningful learning. The results of the presented analysis allow to verify the use of these teaching techniques by professors of the Department of Mechanical and Electrical Engineering. This activity was developed as a part of the work established by the Institutional Development Plan of the Faculty of Engineering, which includes the strategic objective of developing an innovative educational model in the following ten years.

    Should childbirth educators connect education theory to technique? Is there more to learning about theorists than memorizing facts for an assessment? Are childbirth educators uniquely poised to glean wisdom from theorists and enhance their classes with interactive techniques inspiring participant knowledge and empowerment? Yes, yes, and yes. This article will explore how an awareness of education theory can enhance retention of material through interactive learning techniques. Lamaze International childbirth classes already prepare participants for the childbearing year by using positive group dynamics; theory will empower childbirth educators to address education through well-studied avenues. Childbirth educators can provide evidence-based learning techniques in their classes and create true behavioral change.

    2007-12-01

    Full Text Available To identify and describe the basis upon which instructors make curricular and pedagogical decisions, we have developed an artifact-based interview and an analysis technique based on multilayered concept maps. The policy capturing technique used in the interview asks instructors to make judgments about concrete instructional artifacts similar to those they likely encounter in their teaching environment. The analysis procedure alternatively employs both an a priori systems view analysis and an emergent categorization to construct a multilayered concept map, which is a hierarchically arranged set of concept maps where child maps include more details than parent maps. Although our goal was to develop a model of physics faculty beliefs about the teaching and learning of problem solving in the context of an introductory calculus-based physics course, the techniques described here are applicable to a variety of situations in which instructors make decisions that influence teaching and learning.

    Planetary and space science is the best way to teach basic chemistry, physics, and math. Einstein once said that 'man is drawn to the mysterious and it is from that that we achieve true art and science.' Planets and the processes that shape them are especially mysterious and fascinating to students, young and old, and because of this planetary geology kindles interest that draws them further into the world of science. At the very least, they are engaged enough to learn how science works, a key ingredient in scientific literacy. A project involving field measurements on Kilauea volcano, Hawaii, by a Geology 101 honors class is described. Hawaii is blessed with spectacular, active, accessible, and relatively safe basaltic eruptions. The study of volcanoes, the landforms they produce, and the processes that operate on and in volcanoes, combined with the study of volcanoes on the other planets, is an excellent way to link aspects of Hawaiian geology to the planets. During the past year we have taken advantage of our setting to organize a NASA field workshop for junior investigators and senior graduate students, made field trips and planetary volcanism the centerpieces of our annual Summer Workshop for Teachers, and led a field trip around Kilauea Volcano during the Challenger Center Faculty Development conference, held on the island of Hawaii last summer. An activity for the honors Geology 101 class (all undergraduates) at the University of Hawaii is presently being planned. Our goal is to give them some hands on experience working on a field project and applying what they have learned to planetary volcanoes. The work will include qualitative observations and quantitative measurements on volcanic lava flows. Follow-up activities will involve data analysis. The trip requires planning (at least 3 months before hand) everything from accommodations and insurance to the actual activities we will be doing. Our goal is to stimulate interest and awareness in the students

    Direct teaching procedures are often an important part of early intensive behavioral intervention for consumers with autism spectrum disorder. In the present study, a video model with voiceover (VMVO) instruction plus feedback was evaluated to train three staff trainees to implement a most-to-least direct (MTL) teaching procedure. Probes for generalization were conducted with untrained direct teaching procedures (i.e., least-to-most, prompt delay) and with an actual consumer. The results indicated that VMVO plus feedback was effective in training the staff trainees to implement the MTL procedure. Although additional feedback was required for the staff trainees to show mastery of the untrained direct teaching procedures (i.e., least-to-most and prompt delay) and with an actual consumer, moderate to high levels of generalization were observed.

    Splinting is a multistep procedure that is seldom performed by primary care physicians. Just-in-time training (JITT) is an emerging teaching modality and can be an invaluable asset for infrequently performed procedures or in locations where teaching resources and trained professionals are limited. Our objective was to determine the utility of JITT for teaching medical students the short-arm (SA) volar splinting technique. This was a prospective randomized controlled pilot study. An instructional video on SA volar splinting was produced. Students viewed the video or had access to standard medical textbooks (control group) immediately before applying an SA volar splint. The students were assessed for the quality of the splint via a standard 6-point skills checklist. The times required for presplinting preparation and for completion of the splint were also measured. Just-in-time training group students scored higher on the splint checklist (mean [SD], 5.45 [1.06]; 95% confidence interval [CI], 4.99-5.92 vs mean [SD], 1.58 [1.12]; 95% CI, 1.04-2.12; P teaching and disseminating procedural skills, such as SA volar splinting.

    2013-02-01

    Microteaching, a teacher training technique currently practiced worldwide, provides teachers an opportunity to perk up their teaching skills by improving the various simple tasks called teaching skills. With the proven success among the novice and seniors, microteaching helps to promote real-time teaching experiences. The core skills of microteaching such as presentation and reinforcement skills help the novice teachers to learn the art of teaching at ease and to the maximum extent. The impact of this technique has been widely seen in various forms of education such as health sciences, life sciences, and other areas. The emerging changes in medical curricula by the Medical Council of India and the role of medical teachers envisage the need of this special training of teachers and monitoring of their skills for their continued efficient performance at any age. The alleged limitations of microteaching can be minimized by implementing this at the departmental level in several sequences. The author made literature search of research and review articles in various educational databases, journals, and books. From the reference list of published articles, books were also reviewed. This paper presents an outline of the various phases of microteaching, core teaching skills, implementation aspects, and the impact of microteaching on medical education.

    Full Text Available This paper will highlight successful teaching techniques used in class in teaching the Malay Language 1 course in Universiti Sains Malaysia (USM. The course is to equip foreign students for their studies and also as means of basic communication with the locals in Malaysia. In Malaysia, the emphasis in Malay language teaching are focused to Malaysians and had been on grammar structure. There has been little development of teaching of Malay as a foreign language. However, the effort to introduce Malay as a foreign language is important since generally there are a growing number of learners who are aware of the benefits. Other than travelers guide and basic Malay phrase books, not many materials are found for teaching of Malay as a foreign language. Based on the lack of resources, teachers have to incorporate techniques to be used in class to teach the Malay language course. It is hoped that other foreign language teachers will find information useful especially in the teaching the Malay Language as a foreign language.

    Full Text Available The objective of this study was to investigate the reactions of undergraduate and graduate students to the teaching procedures used in semipresential classes. This exploratory study was performed with a quantitative approach at a public university, with undergraduate and graduate students who had completed semipresential classes on health promotion education. Among the 19 evaluated teaching procedures, 15 (78.9% did not show any statistically significant differences between the two academic levels. The means and medians for most variables, for both undergraduate (78.9% and graduate (89.5% students, were above 7 in a scale ranging between 0 (awful and 10 (excellent. Therefore, it is concluded that both groups showed similar reactions to the teaching procedures and gave satisfactory opinions in this regard. Understanding these aspects can support designing class disciplines that use teaching procedures that are adequate to university students.

    Full Text Available This study looks at Student Teams-Achievement Division (STAD implementation from a qualitative approach by observing and interviewing a teacher who successfully improved his EFL students’ reading achievement with this technique. The procedures by Shaaban and Ghaith (2005 were the foundation for STAD implementation, and an interview was done to exhibit the teacher’s stance on the use of STAD. Based on our observation during his teaching in a reading class by implementing STAD, it was found that he did not implement one procedure of this technique, which was assigning a role for each member of the groups. From the interview, he informed that he did not conduct this procedure because he believed that assigning roles should be entrusted to the students to increase their sense of responsibility towards the accomplishment of the group task. Furthermore, he also modified five procedures from nine procedures of STAD proposed by Shaaban and Ghaith (2005. The modified procedures were related to the way the quiz was given to students, providing printed answer key, ways of correcting the student’s quiz, providing the team recognition form, and ways of recognizing the students’ achievement. He informed that they were modified due to the efficacy of students, time limitation and the school’s financial problem.

    In isolated area in Japan, only one anesthesiologist must often do new anesthetic techniques such as ultrasound-guided procedures without receiving any teaching. One solution to this problem may involve teleanesthesia, by which experienced anesthesiologists teach novices in remote places, by utilizing information communication technologies. FaceTime™ (Apple, USA), which provides 120p of the resolution and 30 frames per second (fps) is an application of free visual communications using iPod Touch™, iPhone™ or iPad™ (Apple, USA). We investigated the delay time, the loss of the frames and the picture quality of iPad (as the device in the teaching site) in combination with iPod Touch, iPhone4 or iPhone5 (as the device in the isolated site) during FaceTime. At the operating rooms in Sado General Hospital (SGH) located in Sado Island (population; approximately 60,000), Japan, an anesthesiologist prepared 3 mobile devices (iPod Touch, iPhone4 or iPhone5). He called the other anesthesiologist at Yokohama City University Hospital (YCUH; approximately 300 km apart) by FaceTime using 1 of 3 mobile devices. The anesthesiologist at YCUH received the FaceTime call using iPad. After the connection was established, the display of the same cervical ultrasound image at SGH was sent to YCUH to evaluate the distinctness visually. Then we measured the delay time of every second (n = 60) and the loss of the frames (total frames = 30 fps × 60 s = 1,800) in each device for a minute. P iPod Touch; 0.14 ± 0.02 s, iPhone4; 0.13 ± 0.02 s, iPhone5; 0.19 ± 0.03 s), but clinically acceptable. The loss of the frames of iPhone5 (20; 1.1%) was significantly less than the others (iPhone4; 900, 50.0%, iPod Touch; 902, 50.1%). To teach anesthetic techniques in remote place by FaceTime, iPhone5 as the devise in isolate site was optimum compared with iPod Touch and iPhone4.

    Full Text Available Introducing vocabulary has never been very problematic nor a doubt generating aspect in teaching a language, at least not in respect of what has to be done actually along this part of the lesson or how this stage should be approached. It cannot be said that it has ever been too much of a challenge, but rather a simple and straightforward phase in the economy of the English class. Business English vocabulary teaching methods have to make allowance for the specificity of the field, though. Thus, much consideration has to be given to the way Business English lexical units are introduced so that the technique used could produce the desired results into the students: acquisition of specific terminology, assimilation of meanings and development of skills that shall ensure accurate usage of the terms in the future. After an experimental semester, most adequate class approaches to serve the purposes abovementioned proved to be – rather non-academic, it may be argued – the word games. The current study presents the detailed steps of two distinct teaching methods used and the comparative results obtained with the two groups of students submitted to the experiment. Along the Business English courses in one semester, there were four vocabulary introduction lessons. The nonconformist technique of word games was implemented to one of the two groups of students while the other was taught the regular style. The comparative study focused on several aspects, from the observation of the class reactions and participation along the process of teaching, i.e. response to the didactic process during each class, to the checking of the effects of both types of implementation, namely assessing assimilation of the previously taught material in terms of knowledge of vocabulary and correct interpretation, by random tests and by final test results. If teaching methodologies regularly claim that the general to particular approach is the most effective, here a vice

    We present a dental training system with a haptic interface that allows dental students or experts to practice dental procedures in a virtual environment. The simulator is able to monitor and classify the performance of an operator into novice or expert categories. The intelligent training module allows a student to simultaneously and proactively follow the correct dental procedures demonstrated by an intelligent tutor. The virtual reality (VR) simulator simulates the tooth preparation procedure both graphically and haptically, using a video display and haptic device. We evaluated the performance of users using hidden Markov models (HMMs) incorporating various data collected by the simulator. We implemented an intelligent training module which is able to record and replay the procedure that was performed by an expert and allows students to follow the correct steps and apply force proactively by themselves while reproducing the procedure. We find that the level of graphics and haptics fidelity is acceptable as evaluated by dentists. The accuracy of the objective performance assessment using HMMs is encouraging with 100 percent accuracy. The simulator can simulate realistic tooth surface exploration and cutting. The accuracy of automatic performance assessment system using HMMs is also acceptable on relatively small data sets. The intelligent training allows skill transfer in a proactive manner which is an advantage over the passive method in a traditional training. We will soon conduct experiments with more participants and implement a variety of training strategies.

    The relationship between art and technique has been along the time one that is inseparable and systematic, artists appealing to various technologies, tools and practices that help them stimulate their imagination. Today there is a new category of artists, coming from a technical or scientific field, that are being 'trapped’ in this ‘game of art”. The mosaic, even if it is an old technique, responded to the social requirements and it evolved over time, being constantly related to aesthetic and artistic thinking, discoveries of science, assimilating permanent new techniques and technologies, diversifying its artistic forms of expression and methods of transposition. Not being bound any more to a religious institution, which was its birth place, today, she migrated to all public spaces. Works of art in public space have become today an active factor in reshaping the urban aesthetic landscape.

    We give an overview of our experience in teaching two computational geophysics classes at the undergraduate level. In particular we describe The first class is for most students the first programming class and assumes that the students have had an introductory course in geophysics. In this class the students are introduced to basic Matlab skills: use of variables, basic array and matrix definition and manipulation, basic statistics, 1D integration, plotting of lines and surfaces, making of .m files and basic debugging techniques. All of these concepts are applied to elementary but important concepts in earthquake and exploration geophysics (including epicentre location, computation of travel time curves for simple layered media plotting of 1D and 2D velocity models etc.). It is important to integrate the geophysics with the programming concepts: we found that this enhances students' understanding. Moreover, as this is a 3 year Bachelor program, and this class is taught in the 2nd semester, there is little time for a class that focusses on only programming. In the second class, which is optional and can be taken in the 4th or 6th semester, but often is also taken by Master students we extend the Matlab programming to include signal processing and ordinary and partial differential equations, again with emphasis on geophysics (such as ray tracing and solving the acoustic wave equation). This class also contains a project in which the students have to write a brief paper on a topic in computational geophysics, preferably with programming examples. When teaching these classes it was found that active learning techniques, in which the students actively participate in the class, either individually, in pairs or in groups, are indispensable. We give a brief overview of the various activities that we have developed when teaching theses classes.

    Personalized therapies play an increasingly critical role in cancer care: Image guidance with multimodality image fusion facilitates the targeting of specific tissue for tissue characterization and plays a role in drug discovery and optimization of tailored therapies. Positron-emission tomography (PET), magnetic resonance imaging (MRI), and contrast-enhanced computed tomography (CT) may offer additional information not otherwise available to the operator during minimally invasive image-guided procedures, such as biopsy and ablation. With use of multimodality image fusion for image-guided interventions, navigation with advanced modalities does not require the physical presence of the PET, MRI, or CT imaging system. Several commercially available methods of image-fusion and device navigation are reviewed along with an explanation of common tracking hardware and software. An overview of current clinical applications for multimodality navigation is provided.

    This study aims to identify the tools available to disseminate the Earth sciences to young people in Brazil and to propose new techniques that may help in the teaching of such subjects. The use of scientific dissemination can be a great tool for the consolidation of a scientific culture, especially for a public of young students. The starting point of this study is an important characteristic that is present in virtually all the children: curiosity. The young public tries to understand how the world is and how it works. The use of scientific dissemination and some educational experiences have shown that these students have a great ability to learn and deal with various topics within the Earth Sciences. Another relevant point is the possibility to show that the Earth sciences, e.g., geophysics, oceanography, meteorology, geology and geography, can be an educational attractive option. Several ways of disseminating Earth sciences are commonly used with the purpose of attracting and mainly teaching these subjects, such as websites, interactive museums and cultural and educational spaces. The objectives of this work are: i) Investigate the role of science centers as motivators in disseminating the scientific knowledge by examining the communication resources that are being employed, the acceptance, reaction, and interest of children to these means, and ii) From this analysis, to list suggestions of contents and new tools that could be used for obtaining better results.

    Since the initial hour after injury is the most crucial time for trauma patients, resuscitation technique is of vital importance. Standardized courses for first-hour management (ATLAS) have been widely accepted. A teaching format based upon video recording of every resuscitation has been developed. Tapes are reviewed by the staff and by the individuals involved in a particular resuscitation. In a weekly resuscitation review conference, actual footage is presented to the trauma team members, specific aspects of a resuscitation are critiqued, and supplemental didactic information is presented. Legal problems have been avoided by making the review and conference a part of the quality assurance process. Patient anonymity is preserved by positioning the video camera at the foot of the resuscitation bed. Tapes are erased after each conference. Video recording allows analysis of: 1) priorities during the resuscitation; 2) cognitive integration of the workup by the team leader; 3) physical integration of the workup by the team leader; 4) team member adherence to assigned responsibilities, resuscitation time, errors or breaks in technique; and 5) behavior change over time. In 3 1/2 years, more than 2,500 resuscitations have been recorded. Over a 3-month period, average resuscitation time to definitive care decreased for age- and injury severity-matched patient groups cared for by one team. Resuscitations have become more efficient and adherence to assigned responsibilities better. Weekly review of resuscitation contributes to improved technique and trauma care.

  18. What Child Analysis Can Teach Us about Psychoanalytic Technique.

    Science.gov (United States)

    Ablon, Steven Luria

    2014-01-01

    Child analysis has much to teach us about analytic technique. Children have an innate, developmentally driven sense of analytic process. Children in analysis underscore the importance of an understanding and belief in the therapeutic action of play, the provisional aspects of play, and that not all play will be understood. Each analysis requires learning a new play signature that is constantly reorganized. Child analysis emphasizes the emergence and integration of dissociated states, the negotiation of self-other relationships, the importance of co-creation, and the child's awareness of the analyst's sensibility. Child analysis highlights the robust nature of transference and how working through and repairing is related to the initiation of coordinated patterns of high predictability in the context of deep attachments. I will illustrate these and other ideas in the description of the analysis of a nine-year-old boy.

    In the last years, the interest into interventional applications of C-arm cone-beam CT (CBCT) progressively raised, widening its clinical application from the original field of interventional neuroradiology to the field of peripheral procedures. Liver embolization procedures, due to their complexity and potential treatment-related life-threatening complications, represent one of the main clinical applications of this novel angiographic technique. CBCT has been demonstrated to render procedures safer and technically easier, and to predict outcome as well as to avoid major complications in different treatment scenarios (trans-arterial embolization, trans-arterial chemoembolization, selective internal radiation therapy, percutaneous portal vein embolization). This review summarizes all technical, dosimetric and procedural aspects of CBCT techniques, underlying all its potential clinical advantages in the field of liver embolization procedures. Moreover, the paper provides all the instructions to obtain the best diagnostic performance out of this novel angiographic technique.

    Osteoarthritis of distal radioulnar joint (DRUJ) leads to chronic wrist pain, weakness of grip strength, and limitation of motion, all of which affect the quality of life of the patient. Over the years, several procedures have been used for the treatment of this condition; however, this condition still remains a therapeutic challenge for the hand surgeons. Many procedures such as Darrach procedure, Bower procedure, Sauvé-Kapandji procedure, and ulnar head replacement have been used. Despite many advances in wrist arthroscopy, arthroscopy has not been used for the treatment of arthritis of the DRUJ. We describe a novel technique of arthroscopically assisted Sauvé-Kapandji procedure for the arthritis of the DRUJ. The advantages of this technique are its less invasive nature, preservation of the extensor retinaculum, more anatomical position of the DRUJ, faster rehabilitation, and a better cosmesis.

    Barnes, R W; Lang, N P; Whiteside, M F

    1989-07-01

    This paper reviews the laboratory models used to teach fundamental surgical skills in our general surgery residency. The laboratory modules allow supervision and self-instruction, practice, and videotape monitoring of the following techniques: skin incision, suturing, knot tying, hemostasis, vascular anastomosis, and intestinal anastomosis. Pigs' feet simulate human skin for exercises in skin incision, lesion excision, suturing, and basic plastic surgical techniques. Latex tubing and penrose drains allow experience in suturing, knot tying, and hemostasis. Polytetrafluoroethylene vascular prostheses permit quantification of the precision of needle passage and suturing by measurement of leakage of water through a vascular anastomosis. Reconstituted, lyophilized, irradiated bovine arteries and ileum provide models of biologic tissue for creating handsewn vascular anastomoses and sutured or stapled gastrointestinal anastomoses. A headlamp videocamera allows unobstructive recording of the resident's technical performance and provides subsequent visual feedback for self-improvement when compared to reference instructional videotapes. We feel that these innovations may enhance surgical dexterity of residents without the need for animal sacrifice. Our goal is to foreshorten the learning curve for basic surgical skills and improve performance in the clinical operating room.

  6. Subliminal Cues While Teaching: HCI Technique for Enhanced Learning

    Full Text Available This paper presents results from an empirical study conducted with a subliminal teaching technique aimed at enhancing learner's performance in Intelligent Systems through the use of physiological sensors. This technique uses carefully designed subliminal cues (positive and miscues (negative and projects them under the learner's perceptual visual threshold. A positive cue, called answer cue, is a hint aiming to enhance the learner's inductive reasoning abilities and projected in a way to help them figure out the solution faster but more importantly better. A negative cue, called miscue, is also used and aims at obviously at the opposite (distract the learner or lead them to the wrong conclusion. The latest obtained results showed that only subliminal cues, not miscues, could significantly increase learner performance and intuition in a logic-based problem-solving task. Nonintrusive physiological sensors (EEG for recording brainwaves, blood volume pressure to compute heart rate and skin response to record skin conductivity were used to record affective and cerebral responses throughout the experiment. The descriptive analysis, combined with the physiological data, provides compelling evidence for the positive impact of answer cues on reasoning and intuitive decision making in a logic-based problem-solving paradigm.

    2011-01-01

    While numerous authors acknowledge the challenge of teaching simultaneously to medical students, interns, and residents, few offer specific advice on how to meet that challenge, and none have studied which techniques are most effective. The purpose of this study was to determine whether multilevel teaching is challenging for attendings, whether trainees feel that teaching on rounds is appropriate to their level, and to define multilevel teaching techniques. We surveyed attendings and trainees on the internal medicine services at two academic medical centers. Attendings were divided about whether teaching to multiple levels posed a challenge. Trainees reported that the teaching they received was usually appropriate to their level of training. The most effective techniques for multilevel teaching were Broadening (asking "what if" questions), Targeting (directing questions at specific team members), and Novelty (teaching newly published information), while the least effective were techniques that taught advanced material unfamiliar to most or all of the team. A systematic literature review yielded no studies that focused on multilevel teaching techniques. This article is the first to define and evaluate specific techniques for multilevel instruction in a medical setting and identifies certain techniques as more effective at engaging multiple levels of learners simultaneously.

    2011-03-01

    To evaluate a model used to impart advanced wound closure skills because available models do not meet the necessary requirements to a substantial degree. Seventy-one residents were asked to evaluate a 75-minute-long skills course using cadaveric cattle digits to learn Z-plasty, V-Y-plasty, and oval-shaped rotational flaps. A short film and the course instructor demonstrated each technique first. A Likert rating scale ranging from 1 to 6 was used for questions in the survey given to the residents. There was strong agreement among residents (1.65 ± 1.17 years of experience) that advanced wound closure training courses are necessary (5.73 ± 0.73), which corresponded to the residents' low level of knowledge and self-assessment of practical skills and present experience (2.84 ± 1.01). The course was evaluated with high acceptance, even though it was found to be demanding for the trainees (5.84 ± 0.40). This might also be related to the high rating of the model itself, which was found to be a suitable method for teaching advanced wound closure techniques (5.50 ± 0.71) that was easily comprehensible (5.73 ± 0.53). Skills training courses for young trainees are warranted to impart advanced wound closure techniques. The curriculum using cattle digits presented here is recommended. The authors have indicated no significant interest with commercial supporters. © 2011 by the American Society for Dermatologic Surgery, Inc.

    This article describes the activities of the "Münchener Modell," a project for "Integration of Natural Healing Procedures into Research and Teaching" at the Ludwig-Maximilian University in Munich. Its objective is to improve research and teaching of Natural Healing Procedures (NHPs) and to provide the infrastructural and conceptual prerequisites for the establishment of an independent academic institution. In the years 1989 to 1992 the project organized three 1-year pregraduate courses of NHPs for medical students. Parts of the courses have now been integrated in the regular undergraduate education. In 1993 a quality assurance project for postgraduate education was piloted. In a network of clinics using NHPs a comprehensive quality assurance project including observational studies and controlled clinical trials has been implemented and piloted. For evaluating the actual state of knowledge in a transparent way the project performs systematic reviews of published research. Further clinical-experimental research is being done in the area of immunomodulation with natural products.

    In this study, we examined the regularly scheduled, formal teaching sessions in a single anesthesiology residency program to (1) map the most common primary instructional methods, (2) map the use of 10 known teaching techniques, and (3) assess if residents scored sessions that incorporated active learning as higher quality than sessions with little or no verbal interaction between teacher and learner. A modified Delphi process was used to identify useful teaching techniques. A representative sample of each of the formal teaching session types was mapped, and residents anonymously completed a 5-question written survey rating the session. The most common primary instructional methods were computer slides-based classroom lectures (66%), workshops (15%), simulations (5%), and journal club (5%). The number of teaching techniques used per formal teaching session averaged 5.31 (SD, 1.92; median, 5; range, 0-9). Clinical applicability (85%) and attention grabbers (85%) were the 2 most common teaching techniques. Thirty-eight percent of the sessions defined learning objectives, and one-third of sessions engaged in active learning. The overall survey response rate equaled 42%, and passive sessions had a mean score of 8.44 (range, 5-10; median, 9; SD, 1.2) compared with a mean score of 8.63 (range, 5-10; median, 9; SD, 1.1) for active sessions (P = 0.63). Slides-based classroom lectures were the most common instructional method, and faculty used an average of 5 known teaching techniques per formal teaching session. The overall education scores of the sessions as rated by the residents were high.

    Emergency procedures have been traditionally taught in live "hands on" workshops, which are expensive (tuition, travel, hotel, and leaving one's practice idle). This study was conducted to compare the teaching efficacy of a traditional live workshop to a procedure-in-a-box toolkit (PBT) method which contains audiovisual instructions and props to practice the procedures. Four procedures, zipper release, intraosseous needle placement, fishhook removal, and splinting, were taught to 32 physician volunteers, using both teaching methods. Each participant was asked to evaluate the teaching method after each session. The mean educational quality of each method were not significantly different from each other, but if given a choice study subjects preferred the live workshop more often. The live workshop is the preferable method for teaching procedures but when considering expenses, most of the subjects felt that the PBT method is an adequate substitute method for the live workshop.

    The aim of this study was to examine the impact of psychomotor operative video demonstrations on first-year dental students who are performing specific procedures for the first time in a preclinical setting. The class was randomly divided into two groups, and three restorative procedures were selected. On the date on which each procedure was to be performed in the preclinical laboratory for the first time, one group (experimental, n=50) was shown a technique video for that specific procedure immediately before commencing the exercise; the control cohort (n=50) did not view the video. Technical performance on procedures was evaluated by students and two calibrated and blinded examiners. The students' perceptions of the experience were also collected in a survey. All first-year students participated in the study, for a 100% response rate. A Mann-Whitney U test did not show any group differences in technical performance (mean values on preparation: 77.1 vs. 77.8; amalgam: 82.7 vs. 82.8; composite: 79.7 vs. 78.0). A Spearman rho test revealed a significantly higher correlation in 13 out of 25 evaluation categories between student self-assessment and blinded examiner assessment for the experimental group. A chi-square test of questionnaire responses revealed a positive student perception of administering these videos for the preparation (X(2)=4.8, pstudent performance on preclinical operative procedures, but they were well received by students and augmented self-assessment ability. These findings suggest that videos can be a useful teaching aid in a preclinical environment, especially regarding comprehension of concepts.

    The Bristow-Latarjet procedure is a well-known surgical technique designed to treat shoulder instability. In this procedure, the coracoid process is transferred to the glenoid rim, to serve as augmentation of an associated bony defect. Because long-term results following a soft tissue procedure (Bankart repair) reveal that up to 21 and 33 % of the patients might experience recurrent instability and with the advent of the arthroscopic coracoid transfer, there is renewed interest in this procedure to treat shoulder instability. The aim of this study is to provide a historical overview, with emphasis on the original inventors Bristow and Latarjet, the complications and following modifications regarding the surgical approach, the coracoid transfer and the arthroscopic technique.

    Full Text Available Summary: Secondary correction of nipple areola complex (NAC malposition represents a major concern after breast reconstructive procedures. It is frequently requested by patients complaining about asymmetric areolas impairing the whole reconstructive procedure and asking for improved cosmetic outcomes. Several methods have been described to achieve a good symmetry between the 2 areolas, either natural or reconstructed. We describe our correction technique with free NAC graft. A total of 16 patients were treated with free NAC grafts between April 2010 and April 2013 at the European Institute of Oncology, Milan, Italy. This series focused on the surgical technique and its postoperative outcomes. Three cases of partial graft loss (18% were observed in the postoperative period. No total NAC necrosis occurred. No infection was observed. All the complications were managed with a conservative treatment, not requiring any further surgery. NAC malposition following breast reconstructive procedures can be corrected using the technique of free NAC graft with reliable and satisfactory results.

    A variety of operative techniques have been described as under the term 'Bristow-Latarjet' procedure. This review aims to define the original procedure, and compare the variation in techniques described in the literature, assessing any effect on clinical outcomes. A systematic review of 24 studies was performed to compare specific steps of the technique (coracoid osteotomy site, subscapularis approach, orientation and position of coracoid graft fixation and fixation method, additional labral and capsular repair) and detect any effect this variability had on outcomes. Overall recurrence rate was 5.36% (2.94% to 43%). Half of the studies performed the procedure for recurrent shoulder instability, with only five studies documenting glenoid bone loss as an indication: 12 studies used the procedure as the primary surgical intervention for recurrent instability. No change in outcome was noted when examining variation in the coracoid osteotomy site, the fixation site on the scapular neck, the fixation method or whether a capsular repair was also performed. Performing a horizontal split in subscapularis may preserve external rotation compared with performing a tenotomy. This is the first review to examine various operative techniques of the Bristow-Latarjet procedure, and their effect on outcome. We found that other than the approach through subscapularis, outcome was independent of the surgical technique, and depended more on patient selection. We would commend future publications on this procedure to provide a detailed description of the surgical technique, and as a minimum present rates of recurrence as an outcome measure.

    Full Text Available Learning styles have been a particular focus of a number of researchers over the past decades. Findings from various studies researching into how students learn highlight significant relationships between learners’ styles of learning and their language learning processes and achievement. This research focuses on a comparative analysis of the preferences of English learning styles and teaching techniques perceived by students from Thailand and Vietnam, and the teaching styles and techniques practiced by their instructors. The purposes were 1 to investigate the learning styles and teaching techniques students from both countries preferred, 2 to investigate the compatibility of the teaching styles and techniques practiced by instructors and those preferred by the students, 3 to specify the learning styles and teaching techniques students with high level of English proficiency preferred, and 4 to investigate the similarities of Thai and Vietnamese students’ preferences for learning styles and teaching techniques. The sample consisted of two main groups: 1 undergraduate students from King Mongkut’s University of Technology North Bangkok (KMUTNB, Thailand and Thai Nguyen University (TNU, Vietnam and 2 English instructors from both institutions. The instruments employed comprised the Students’ Preferred English Learning Style and Teaching Technique Questionnaire and the Teachers’ Practiced English Teaching Style and Technique Questionnaire. The collected data were analyzed using arithmetic means and standard deviation. The findings can contribute to the curriculum development and assist teachers to teach outside their comfort level to match the students’ preferred learning styles. In addition, the findings could better promote the courses provided for students. By understanding the learning style make-up of the students enrolled in the courses, faculty can adjust their modes of content delivery to match student preferences and maximize

    The Latarjet procedure is commonly performed using either the classic or the congruent-arc technique. Each technique has potential clinical advantages and disadvantages. However, data on the anatomic and biomechanical effects, benefits, and limitations of each technique are limited. Hypothesis/Purpose: To compare the anatomy and biomechanical fixation strength (failure load) between the 2 techniques. It was hypothesized that the classic technique would have superior initial fixation when compared with the congruent-arc technique and that this would be affected by sex and coracoid size. Controlled laboratory study. A biomechanical cadaver study was performed with 20 pairs of male and female shoulders. One of each pair of shoulders was randomly assigned to receive the classic or congruent-arc technique. Coracoid and glenoid anatomic measurements were collected before biomechanical testing. A tensile force was applied through the conjoined tendon to replicate forces experienced by the coracoid graft in the early postoperative period, and the failure load was determined for each specimen. The mean ± SD surface area available for fixation was 263 ± 63 mm(2) in the classic technique compared with 177 ± 63 mm(2) in the congruent-arc group ( P Latarjet procedure provided a greater surface area for healing to the glenoid and superior initial fixation when compared with the congruent-arc technique. The congruent-arc technique allowed restoration of a larger glenoid defect. The classic and congruent-arc techniques of coracoid transfer have anatomic and biomechanical advantages and disadvantages that should be considered when choosing between the 2 techniques.

    2011-11-01

    Full Text Available We present here a technique of fracture stabilization using the Tightrope procedure in a patient with a widely displaced Neer type IIB distal clavicle fracture. The Tightrope system, typically used for stabilization of acromioclavicular joint dislocation, has not been widely described for distal clavicle fractures. The patient achieved satisfactory results after surgery; we feel that this technique is appealing as it is simple, reproducible and avoids the complications associated with extensive metalwork. This technique may also appeal to the arthroscopic surgeon.

    The proportion of men receiving non-surgical cosmetic procedures has risen substantially in recent years. Various physiologic, anatomic, and motivational considerations differentiate the treatments for male and female patients. Nevertheless, research regarding approaches to the male cosmetic patient is scarce. We sought to provide an overview and sex-specific discussion of the most popular cosmetic dermatologic procedures pursued by men by conducting a comprehensive literature review pertaining to non-surgical cosmetic procedures in male patients. The most common and rapidly expanding non-surgical interventions in men include botulinum toxin, filler injection, chemical peels, microdermabrasion, laser resurfacing, laser hair removal, hair transplantation, and minimally invasive techniques for adipose tissue reduction. Important sex-specific factors associated with each of these procedures should be considered to best serve the male cosmetic patient.

    Each year, rheumatology programs across the country teach incoming trainees the skill of arthrocentesis, but the relative effectiveness of various teaching techniques has not been assessed in a systematic way. We compared approaches to teaching arthrocentesis using cadavers versus anatomic models. In a pilot study, new rheumatology fellows (n = 7) from 2 academic institutions were surveyed at 3 points during arthrocentesis training: (1) before assuming patient care; (2) after lecture with handouts, followed by practice either on cadavers (group A) or on synthetic joint models (group B); and (3) 6 weeks into fellowship. Fellows rated their comfort levels for arthrocentesis of specific joints using 9-point Likert scales. Fellows also retrospectively rated the utility of individual teaching modalities in helping them to learn. As a follow-up study, internal medicine residents taking part in a month-long rheumatology rotation were similarly surveyed on their comfort level performing knee and shoulder arthrocentesis before a cadaver teaching laboratory and at the end of their month rotation. The initial mean comfort level performing arthrocentesis for all fellows was low (2.01). After the cadaver teaching session, group A fellows experienced an overall comfort level increase of 1.95, with the largest single increase reported for shoulder arthrocentesis (3.86). After the anatomic model teaching session, group B fellows reported a mean comfort increase of 1.29, with the largest increase reported for knee arthrocentesis (3.13). The subsequent study with residents confirmed significant increases in comfort after the cadaver laboratory. When surveyed, the learning experience fellows considered most effective was the opportunity to perform procedures under supervision and guidance, followed by training on cadavers. Although all teaching interventions for trainees learning arthrocentesis were helpful for increasing trainee's comfort with arthrocentesis, the use of cadavers

    Quaife, Robert A; Salcedo, Ernesto E; Carroll, John D

    2014-02-01

    The complexity of structural heart disease interventions such as edge-to edge mitral valve repair requires integration of multiple highly technical imaging modalities. Real time imaging with 3-dimensional (3D) echocardiography is a relatively new technique that first, allows clear volumetric imaging of target structures such as the mitral valve for both pre-procedural diagnosis and planning in patients with degenerative or functional mitral valve regurgitation. Secondly it provides intra-procedural, real-time panoramic volumetric 3D view of structural heart disease targets that facilitates eye-hand coordination while manipulating devices within the heart. X-ray fluoroscopy and RT 3D TEE images are used in combination to display specific targets and movement of catheter based technologies in 3D space. This integration requires at least two different image display monitors and mentally fusing the individual datasets by the operator. Combined display technology such as this, allow rotation and orientation of both dataset perspectives necessary to define targets and guidance of structural disease device procedures. The inherently easy concept of direct visual feedback and eye-hand coordination allows safe and efficient completion of MitraClip procedures. This technology is now merged into a single structural heart disease guidance mode called EchoNavigator(TM) (Philips Medical Imaging Andover, MA). These advanced imaging techniques have revolutionized the field of structural heart disease interventions and this experience is exemplified by a cooperative imaging approach used for guidance of edge-to-edge mitral valve repair procedures.

    In current medical curricula, the transfer of procedural skills has received increasing attention. Skills lab learning and tutor-led teaching have become an inherent part of all medical curricula at German medical faculties. In 2011, the initial basis for the classification of clinical skills in medical school was created by the German Association for Medical Education (GMA) Committee's consensus statement on procedural skills. As a recommendation for medical curricula, the National Competency-based Catalogue of Learning Objectives (NKLM, 2015) lists procedural skills according to their curriculum integration and competency level. However, classification in regard to the perceived complexity, relevance, or teaching competency is still lacking. The present study aimed to investigate procedural skills taught at the Medical Faculty of Heidelberg in regard to their complexity, relevance, and required teaching skills. To achieve this aim (1) the specific procedural skills in terms of complexity, that is, the degree of difficulty, and (2) the perceived relevance of taught procedural skills for studying and subsequent medical profession as well as (3) the personal preparation and required teaching skills were assessed in medical teachers, tutors and students. During the winter semester 2014/2015, the evaluations of all medical teachers, student tutors, and medical students in the skills lab teaching departments of internal medicine, surgery, pediatrics, gynecology, and otorhinolaryngology at the Medical Faculty of Heidelberg were assessed via a quantitative cross-sectional questionnaire survey using 7-point Likert scales. The questionnaire comprised four item sets concerning 1) demographic details, 2) procedural skill complexity, 3) practical relevance, and 4) required preparation and teaching skills. Descriptive, quantitative analysis was used for questionnaire data. The survey included the data from 17 of 20 physicians (return rate: 85 %), 10 of 10 student tutors

    Full Text Available The purpose of this study is to determine which teaching strategies, techniques and methods are used by teachers in science and technology classes and also to determine the shortcomings they have. A questionnaire was conducted to a total of 95 teachers, 45 of whom were science and technology teachers and 50 of whom were class teachers, and 33 teachers were interviewed. It was found out that the teachers did not have enough information about teaching strategies, methods and techniques and thus were not able to make a precise distinction between them. It was determined that although the teachers were aware that the most convenient teaching technique is experiment technique, they used direct instruction or question and answer technique more and they sometimes used methods and techniques such as laboratory, trip-observation and drama. It was stated that the teachers were not able to implement teaching methods and techniques in which the students could actively participate due to reasons such as insufficient time, intensive curriculum and overcrowded classes. It was also determined that the teachers who were not able to practice different teaching methods although they knew how useful they were needed in-service training.

Bipolar diathermy cutting and hemostasis was performed using bipolar forceps with a Valleylab machine set at 15. Sleeve circumcision was used. A dorsal slit was made, followed by frenulum release and ventral slit, and was completed with bilateral circumferential cutting. Frenuloplasties released the frenulum. Preputioplasties used multiple 2–3 mm longitudinal cuts to release the constriction, with frenulum left intact. All wounds were closed with interrupted 4/0 Vicryl Rapide™.Results: A total of 54 nonemergency bipolar circumcision procedures were carried out from November 2010–August 2012 (42 circumcisions, eight frenuloplasties, and four preputioplasties. Patients were aged 18–72 years (mean, 34 years. There was minimal to no intraoperative bleeding in all cases, allowing for precise dissection. All patients were requested to attend outpatient reviews; three frenuloplasty and two circumcision patients failed to return. Of the remaining 49, mean interval to review was 49 days, with a range of 9–121 days. Two circumcision patients reported mild bleeding with nocturnal erections within a week postoperatively, but they did not require medical attention. Two others presented to family practitioners with possible wound infections which resolved with oral antibiotics. All 49 patients had well-healed wounds.Conclusion: The bipolar diathermy technique is a simple procedure, easily taught, and reproducible. It is associated with minimal bleeding, is safe and efficient, uses routine operating equipment and

    2015-01-01

    Recently, Six Sigma techniques have been adopted by clinical laboratories to evaluate laboratory performance. Measurement procedures in laboratories can be categorized as "excellent", "good", and "improvement needed" based on sigma (σ) metrics of σ ≥ 6, 3 ≤ σ 1.2 indicates that the trueness of the procedure needs to be improved; 0.8 ≤ QGI ≤ 1.2 indicates that both the precision and trueness of the procedure need to be improved. Fresh frozen sera containing seven enzymes (ALT, ALP, AMY, AST, CK, GGT, and LDH) were sent to 78 clinical laboratories in China. The biases for measurement procedures in each laboratory (Bias) were calculated based on the target values assigned by 18 laboratories performing IFCC (International Federation of Clinical Chemistry and Laboratory medicine) recommended reference methods. The imprecision of each measurement procedure was represented by coefficient variations (CV) calculated based on internal quality control (IQC) data. The σ and QGI values were calculated as follows: σ = (TEa-Bias)/CV; QGI = Bias/(1.5 x CV). TEa is allowable total error for each enzyme derived from biological variation. Our study indicated that 7.9% (6/76, ALP) to 31.0% (18/58, AMY) of the participating laboratories were scored as "excellent" (σ ≥ 6), 21.1% (16/76, ALP) to 41.3% (31/75, CK) of the laboratories were scored as "good" (3 ≤ σ Six Sigma techniques still suggested that approximately 31.1% to 71.0% of the laboratories need to improve their enzyme measurement procedures, either in terms of precision, trueness, or both.

  11. Microextraction Techniques Used in the Procedures for Determining Organomercury and Organotin Compounds in Environmental Samples

    Directory of Open Access Journals (Sweden)

    Małgorzata Rutkowska

    2014-06-01

    Full Text Available Due to human activities, the concentrations of organometallic compounds in all parts of the environment have increased in recent decades. The toxicity and some biochemical properties of mercury and tin present in the environment depend on the concentration and chemical form of these two elements. The ever-increasing demand for determining compounds at very low concentration levels in samples with complex matrices requires the elimination of interfering substances, the reduction of the final extract volume, and analyte enrichment in order to employ a detection technique, which is characterised by high sensitivity at low limits of quantification. On the other hand, in accordance with current trends, the analytical procedures should aim at the miniaturisation and simplification of the sample preparation step. In the near future, more importance will be given to the fulfilment of the requirements of Green Chemistry and Green Analytical Chemistry in order to reduce the intensity of anthropogenic activities related to analytical laboratories. In this case, one can consider the use of solvent-free/solvent-less techniques for sample preparation and microextraction techniques, because the use of the latter leads to lowering the quantity of reagents used (including solvents due to the reduction of the scale of analysis. This paper presents an overview of microextraction techniques (SPME and LPME used in the procedures for determining different chemical forms of mercury and tin.

    Purpose We investigated whether a 3D overlay roadmap using monoplane fluoroscopy offers advantages over a conventional 2D roadmap using biplane fluoroscopy during endovascular aneurysm treatment. Materials and Methods A retrospective chart review was conducted for 131 consecutive cerebral aneurysm embolizations by three neurointerventionalists at a single institution. Allowing for a transition period, the periods from January 2012 to August 2012 (Time Period 1) and February 2013 to July 2013 (Time Period 2) were analyzed for radiation exposure, contrast administration, fluoroscopy time, procedure time, angiographic results, and perioperative complications. Two neurointerventionalists (Group 1) used a conventional 2D roadmap for both Time Periods, and one neurointerventionalist (Group 2) transitioned from a 2D roadmap during Time Period 1 to a 3D overlay roadmap during Time Period 2. Results During Time Period 2, Group 2 demonstrated reduced fluoroscopy time (p<0.001), procedure time (P=0.023), total radiation dose (p=0.001), and fluoroscopy dose (P=0.017) relative to Group 1. During Time Period 2, there was no difference of immediate angiographic results and procedure complications between the two groups. Through the transition from Time Period 1 to Time Period 2, Group 2 demonstrated decreased fluoroscopy time (p< 0.001), procedure time (p=0.022), and procedure complication rate (p=0.041) in Time Period 2 relative to Time Period 1. Conclusion The monoplane 3D overlay roadmap technique reduced fluoroscopy dose and fluoroscopy time during neurointervention of cerebral aneurysms with similar angiographic occlusions and complications rate relative to biplane 2D roadmap, which implies possible compensation of limitations of monoplane fluoroscopy by 3D overlay technique.

    The preceptor is a nurse who teaches and supports the student and is seen as pivotal to student learning within the clinical setting. Earlier studies have shown that preceptors' pedagogical competence is significant for facilitating learning during clinical practice. However, studies describing pedagogical competence, especially in terms of teaching strategies, seem to be scarce. The aim of this study was to describe which strategies and techniques preceptors use to teach undergraduate nursing students during clinical practice. The study had an ethnographic approach; methods used were participant observations and focus group interviews with nurses who were experienced in precepting undergraduate nursing students. Findings illustrated how preceptors used different strategies and techniques in a continuous process of adjusting, performing and evaluating precepting. Increased knowledge on how the preceptors actually teach student nurses during clinical practice will help facilitate educational programmes for preceptors, which will enhance their pedagogical skills and competences.

    Health care delivery and education has become a challenge for providers. Nurses and other professionals are challenged daily to assure that the patient has the necessary information to make informed decisions. Patients and their families are given a multitude of information about their health and commonly must make important decisions from these facts. Obstacles that prevent easy delivery of health care information include literacy, culture, language, and physiological barriers. It is up to the nurse to assess and evaluate the patient's learning needs and readiness to learn because everyone learns differently. This article will examine how each of these barriers impact care delivery along with teaching and learning strategies will be examined.

    The exposure to ultrasound technology in medicine is increasing at multiple training levels. Ultrasound transducers have evolved to provide higher-resolution imaging for more accurate structural identification, with few improvements in ease of use. This study investigated a novel finger ultrasound transducer used by first-year medical students conducting structural identification and practicing an invasive procedure. A literature search was conducted on texts, specialty journals, and websites regarding the anatomy of internal jugular and subclavian vein central line placement with sonographic guidance and the use of a finger transducer. First-year medical students performed timed sonographically guided cannulation on the internal jugular and subclavian veins on a phantom torso and identified the internal jugular and subclavian veins on a healthy volunteer using the finger transducer and a conventional transducer. After exposure to both transducers, a survey was taken regarding transducer preference. The literature search revealed no studies comparing finger and classic transducers or sonographically guided central line techniques being conducted by first-year medical students. The students identified and cannulated the internal jugular and subclavian veins using both transducers. Survey results revealed that 70% of the students preferred the finger transducer. This study showed that first-year medical students could interpret sonographic anatomy while conducting a clinical procedure. The finger transducer proved successful in structure identification and was preferred to the classic transducer because of its combined tactile presence. This pilot study of a novel finger transducer showed the benefits of combining palpatory skills with ultrasound technology in teaching first-year medical students to perform invasive procedures.

    It is estimated that there are over 5 million homeless animals in the United States. While the veterinary profession continues to evolve in advanced specialty disciplines, animal shelters in every community lack resources for basic care. Concurrently, veterinary students, interns, and residents have less opportunity for practical primary and secondary veterinary care experiences in tertiary-care institutions that focus on specialty training. The two main goals of this project were (1) to provide practical medical and animal-welfare experiences to veterinary students, interns, and residents, under faculty supervision, and (2) to care for animals with medical problems beyond a typical shelter's technical capabilities and budget. Over a two-year period, 22 animals from one humane society were treated at Colorado State University Veterinary Medical Center. Initial funding for medical expenses was provided by PetSmart Charities. All 22 animals were successfully treated and subsequently adopted. The results suggest that collaboration between a tertiary-care facility and a humane shelter can be used successfully to teach advanced procedures and to save homeless animals. The project demonstrated that linking a veterinary teaching hospital's resources to a humane shelter's needs did not financially affect either institution. It is hoped that such a program might be used as a model and be perpetuated in other communities.

  3. Instrumentation of Microscale Techniques for Biochemistry Teaching at FES Zaragoza, UNAM

    2015-02-01

    Full Text Available Biochemistry teaching requires many laboratory sessions where theoretical knowledge may be put on test. At the same time, there is always some risk due to exposure to toxic materials, dangerous chemicals storage and waste disposal. Compliance with new regulations to prevent environmental contamination may also constitute a real hindrance for biochemistry teaching as experimental science. Therefore, we have designed microscale techniques, in order to reduce costs as well as the negative impact of laboratory practical sessions due to risk and environmental contamination. To develop microscale techniques does not only mean to reduce equipment size and amount of the reagents that are required for the usual experiments. Microscale techniques serve particularly well as a motivating approach to experimental biochemistry teaching that produces highly motivated students at the same time that requires minor costs, decreases working time, laboratory space, reagents volume and diminishes the generation of dangerous waste. We have demonstrated all these positive effects in biochemistry teaching and prompted the formal implementation of microscale techniques into the formal activities from the Cell and Tissue Biochemistry Laboratory I (BCT-I from the Chemistry, Pharmacy and Biology (QFB curricula at the National Autonomous University of Mexico (UNAM. First, we reviewed the BCT-I manual, choosing all the laboratory practices that might be microscaled. Then, we elaborated and validated all necessary protocols to analyse linearity, accuracy and reproducibility of the determinations, demonstrating that microscale techniques allow truthful results, comparable to full scale techniques.

    Probability Theory and Statistics are two of the most useful mathematical fields, and also two of the most difficult to learn. In other science fields, as Physics, experimentation is an useful tool to develop students intuition, but the application of this tool to Statistics is much more difficult. In this paper we show how Monte Carlo techniques can be used to perform numerical experiments, by the use of pseudorandom numbers, and how these experiments can help to the understanding of Statistics and Physics. Monte Carlo techniques are broadly used in scientific research, but they are learnt usually in very specific curses of higher education. By the use of computer simulation these techniques can also be taught at elementary school and they can help to understand and visualise concepts as variance, mean or a probability distribution function. Finally, the use of new technologies, as Javascript and HTML is discussed.

  6. A Curriculum for Teaching Information Technology Investigative Techniques for Auditors

    Grover S. Kearns

    2006-12-01

    Full Text Available Recent prosecutions of highly publicized white-collar crimes combined with public outrage have resulted in heightened regulation of financial reporting and greater emphasis on systems of internal control. Because both white-collar and cybercrimes are usually perpetrated through computers, internal and external auditors’ knowledge of information technology (IT is now more vital than ever. However, preserving digital evidence and investigative techniques, which can be essential to fraud examinations, are not skills frequently taught in accounting programs and instruction in the use of computer assisted auditing tools and techniques – applications that might uncover fraudulent activity – is limited. Only a few university-level accounting classes provide instruction in IT investigative techniques. This paper explains why such a course would be beneficial to the program, the college, and the student. Additionally, it presents a proposed curriculum and suggests useful resources for the instructor and student.

    Full Text Available In this study, we compared the ex vivo removal capacity of two endodontic rotary techniques and determined whether there was a significant quantitative difference in residual material when comparing root thirds. Forty extracted molars were used. The palatal roots were selected, and the canals were prepared using a step-back technique and filled using a lateral condensation technique with gutta-percha points and Endofill sealer. After two weeks of storage in a 0.9% saline solution at 37ºC in an oven, the specimens were divided into 2 groups of 20, with group 1 samples subjected to Gates-Glidden drills and group 2 samples subjected to the ProTaper retreatment System. Hedstroem files and eucalyptol solvent were used in both groups to complete the removal procedure. Then, the roots thirds were radiographed and the images were submitted to the NIH ImageJ program to measure the residual filling material in mm. Each root third was related to the total area of the root canals. The data were analyzed using Student's t test. There was a statistically significant difference between the two techniques as more filling material was removed by technique 2 (ProTaper than technique 1 (Gates-Glidden drills, p < 0.05. The apical third had a greater amount of residual filling material than the cervical and middle thirds, and the difference was statistically significant (p < 0.05. None of the selected techniques removed all filling material, and the material was most difficult to remove from the apical third. The ProTaper files removed more material than the Gates-Glidden drills

    Mani, Vishnu R.; Ahmed, Leaque

    2015-01-01

    While laparoscopic surgery can be performed using small skin incisions, any resected specimen must still be able to fit through these opening. For procedures, such as cholecystectomies and appendectomies, this is not usually a problem; however, for large specimens such as bowel or large tumors, this becomes problematic. Currently, the standard technique is to attempt piecemeal removal of the specimen or enlarge one of the laparoscopic incisions, effectively creating a mini laparotomy. Creating a larger incision adds many of the drawbacks of open laparotomy and should be avoided whenever possible. In this article, we present a new technique of combining the repair of an inguinal hernia, umbilical hernia with a duodenal tumor resection in order to extract the specimen through the inguinal hernia orifice.

    Frazier, K B; Haywood, V B

    2000-05-01

    Tooth-whitening using carbamide peroxide delivered in a custom-fitted tray (nightguard bleaching) is a relatively new procedure, yet it is currently one of the most commonly used types of esthetic dental treatment in private practice. This study determined the extent that nightguard bleaching (NGB) has been included in dental school curricula. All sixty-five dental schools in North America were surveyed about curriculum content and treatment protocol for the use of nightguard and other bleaching procedures, generating an 82 percent response. The survey covered eighteen subject areas related to NGB ranging from clinical requirements and indications to products and recall intervals used. The most commonly taught tooth-whitening procedure was NGB, which was most often taught by operative and restorative faculty. Although no schools had clinical requirements for NGB, 92 percent taught it. The most common indications for NGB were esthetic shade change and pre-restorative lightening of teeth. Unrestored caries, defective restorations, and pre-existing sensitivity were common contraindications. Most schools do not use a specific NGB consent form, but most use written patient instructions. Most schools use at least two different NGB products, bleach for two to four weeks, and use reservoired and scalloped trays. An average of 25 percent of NGB patients were estimated to develop sensitivity, for which treatment recommendations include fluoride, desensitizing toothpaste, and reduced exposure time. Curriculum time and safety concerns were reasons for not teaching NGB (8 percent schools). Most schools indicated that the relative importance of NGB in the curriculum was increasing.

  14. Force reconstruction using the sum of weighted accelerations technique -- Max-Flat procedure

    Energy Technology Data Exchange (ETDEWEB)

    Carne, T.G.; Mayes, R.L.; Bateman, V.I.

    1993-12-31

    Force reconstruction is a procedure in which the externally applied force is inferred from measured structural response rather than directly measured. In a recently developed technique, the response acceleration time-histories are multiplied by scalar weights and summed to produce the reconstructed force. This reconstruction is called the Sum of Weighted Accelerations Technique (SWAT). One step in the application of this technique is the calculation of the appropriate scalar weights. In this paper a new method of estimating the weights, using measured frequency response function data, is developed and contrasted with the traditional SWAT method of inverting the mode-shape matrix. The technique uses frequency response function data, but is not based on deconvolution. An application that will be discussed as part of this paper is the impact into a rigid barrier of a weapon system with an energy-absorbing nose. The nose had been designed to absorb the energy of impact and to mitigate the shock to the interior components.

    1998-02-01

    Pulmonary angiography (PA) for decades has been accepted as the gold standard for the diagnosis of pulmonary embolism (PE). Apprehensions that the procedure is expensive, invasive and thus associated with both fatal and non-fatal complications has more or less limited its use to patients presenting a non-diagnostic lung scan. However, this opinion originates from earlier studies. Increasing clinical demands for faster and safer diagnostics, together with improved techniques and safer contrast media, has led to an increased use of PA. In order to evaluate the complication rate, we retrospectively studied the case records of 707 consecutive patients who had undergone PA. During 1990-1994, 728 patients underwent PA at Danderyd and Huddinge University Hospital. Selective pulmonary angiography (cine or digital subtraction angiography), non-ionic, low-osmolar contrast media and modern pigtail catheters were used. Standard volumes were 40 ml at 2 s for each injection. Pressure measurements were made in 376 patients. A test injection was made in all patients in order to assess the flow rate. Experienced radiologists as well as residents performed the examinations and a total of 707 angiography protocols and clinical records were available for review in search of complications associated with the procedure. No deaths occurred. One major non-fatal complication (bleeding in the groin requiring surgery) was reported in one case. Moderate/minor complications (i. e. transient angina and cardiac failure, minor haematomas, urticaria) occurred in 10 patients (1.4 %). With modern contrast media and technique, pulmonary angiography is a safe procedure. (orig.) 19 refs.

  19. Evaluation of a Jugular Venipuncture Alpaca Model to Teach the Technique of Blood Sampling in Adult Alpacas.

    Rousseau, Marjolaine; Beauchamp, Guy; Nichols, Sylvain

    2017-05-23

    The effectiveness of teaching aids in veterinary medical education is not often assessed rigorously. The objective in the present study was to evaluate the effectiveness of a commercially available jugular venipuncture alpaca model as a complementary tool to teach veterinary students how to perform venipuncture in adult alpacas. We hypothesized that practicing on the model would allow veterinary students to draw blood in alpacas more rapidly with fewer attempts than students without previous practice on the model. Thirty-six third-year veterinary students were enrolled and randomly allocated to the model (group M; n=18) or the control group (group C; n=18). The venipuncture technique was taught to all students on day 0. Students in group M practiced on the model on day 2. On day 5, an evaluator blinded to group allocation evaluated the students' venipuncture skills during a practical examination using live alpacas. Success was defined as the aspiration of a 6-ml sample of blood. Measured outcomes included number of attempts required to achieve success (success score), total procedural time, and overall qualitative score. Success scores, total procedural time, and overall scores did not differ between groups. Use of restless alpacas reduced performance. The jugular venipuncture alpaca model failed to improve jugular venipuncture skills in this student population. Lack of movement represents a significant weakness of this training model.

  20. Arthroscopic Latarjet and Capsular Shift (ALCS) procedure: a new "freehand" technique for anterior shoulder instability associated with significant bone defects.

    Science.gov (United States)

    Bhatia, Deepak N

    2015-03-01

    Anterior shoulder instability associated with significant bone loss has been described as "bony-instability," and this condition is usually treated with an anterior glenoid bone grafting procedure (Latarjet procedure). The Latarjet procedure involves transfer of the horizontal limb of the coracoid process along with the conjoint tendon to the anterior glenoid rim, and is traditionally performed as an open surgical procedure. Recently, an arthroscopic technique for the Latarjet procedure has been described; the technique necessitates the use of specialized instrumentation and involves excision of the entire anterior capsule to facilitate coracoid fixation. We describe a new "freehand" arthroscopic technique for the Latarjet procedure, and, in addition, a simultaneous capsular shift to further optimize mid and end range stability. This technique eliminates the use of additional instrumentation and can be done using routine arthroscopic instruments. Preliminary experience with this technique suggests that the arthroscopic Latarjet and capsular shift is a technically demanding procedure. Glenohumeral capsule can be preserved, and this should be attempted wherever possible to optimize stability. Additional specialized instrumentation would probably reduce surgical time; however, the procedure can be performed with routine instruments.

    Moragas, Joan San Miguel; Vercruysse, Herman Junior; Mommaerts, Maurice Y

    2014-09-01

    Ideal lip augmentation techniques have good longevity, low complication rates, and optimal functional and aesthetic results. No systematic review is currently available regarding the efficacy of lip augmentation techniques. This review will focus only on non-filling procedures for lip augmentation (NFPLAs). Current databases Elsevier Science Direct, PubMed, HighWire Press, Springer Standard Collection, SAGE, DOAJ, Sweetswise, Free E-Journals, Ovid Lippincott Williams & Wilkins, Willey Online Library Journals and Cochrane Plus were scrutinized and relevant article reference sections were studied for additional publications. The search heading sequence used was ("Lip" or "Mouth" or "Perioral" or "Nasolabial") and ("Augmentation" or "Enhancement" or "Surgery" or "Lift" or "V-Y" or "Corner"). Exclusion criteria applied to 6436 initial keyword-search retrievals yielded 12 articles. Eight more articles were retrieved from reference sections, for a total of 18 papers assessed. Only one article made a direct comparison of efficacy between two surgical techniques for lip augmentation, and none directly compared complications associated with different NFPLAs. Although this systematic review revealed a lack of quality data in comparing the efficacy and complications among different NFPLAs, it is important to review and pool the existing studies to better suggest proper treatment to patients.

  19. An investigative graduate laboratory course for teaching modern DNA techniques.

    Science.gov (United States)

    de Lencastre, Alexandre; Thomas Torello, A; Keller, Lani C

    2017-02-16

    This graduate-level DNA methods laboratory course is designed to model a discovery-based research project and engages students in both traditional DNA analysis methods and modern recombinant DNA cloning techniques. In the first part of the course, students clone the Drosophila ortholog of a human disease gene of their choosing using Gateway(®) cloning. In the second part of the course, students examine the expression of their gene of interest in human cell lines by reverse transcription PCR and learn how to analyze data from quantitative reverse transcription PCR (qRT-PCR) experiments. The adaptability of the Gateway(®) cloning system is ideally suited for students to design and create different types of expression constructs to achieve a particular experimental goal (e.g., protein purification, expression in cell culture, and/or subcellular localization), and the genes chosen can be aligned to the research interests of the instructor and/or ongoing research in a department. Student evaluations indicate that the course fostered a genuine excitement for research and in depth knowledge of both the techniques performed and the theory behind them. Our long-term goal is to incorporate this DNA methods laboratory as the foundation for an integrated laboratory sequence for the Master of Science degree program in Molecular and Cellular Biology at Quinnipiac University, where students use the reagents and concepts they developed in this course in subsequent laboratory courses, including a protein methods and cell culture laboratory. © 2017 by The International Union of Biochemistry and Molecular Biology, 2017.

  20. Using Hollywood techniques to teach freshman astronomy over the Internet

    Science.gov (United States)

    Friedberg, R.; Lipnick, D.; Vila Migliaro, M.

    We use interactive 'click and drag' learning, bold colors, high graphic design standards, cartooning, animations and videos. We present Astronomy material in three languages, written English, written Spanish, and written and spoken Navajo. This distance-learning course is specifically designed for students with limited proficiency in the English language. We have both a lecture and laboratory series in the course that may be found at www.ibe.ncc.cc.nm.us and http://yoda.phys.unm.edu/ast100. It carries 4 hours of credit as Astronomy 100. To paraphrase John Ford, the great Hollywood director, a good movie should be able to stand with no dialogue. We have tried to meet his standard. We have borrowed heavily from the style of the Pvt. Snafu World War II military training films produced principally by the Walt Disney Studios. We have also used the graphic design techniques that I learned many years ago as a technical briefing officer at the Chief of Naval Operation's Briefing Room at the Pentagon, Washington D.C.. Finally, we use elements of 'Programmed Learning' developed by the American Management Association thirty odd years ago. Elements that make our web course unique are: A laboratory on Navajo Astronomy, lectures translated into Spanish, and many collateral resources for student use both internal to our web site and as external links on the Internet. Much of this work was underwritten by NASA grant NAG5-10254.

    Clinician educators face numerous obstacles to their joint mission of facilitating high-quality learning while also delivering patient-centered care. Such challenges necessitate increased attention to the work of exemplary clinician educators, their respective teaching approaches, and the experiences of their learners. To describe techniques and behaviors utilized by clinician educators to facilitate excellent teaching during inpatient general medicine rounds. An exploratory qualitative study of inpatient teaching conducted from 2014 to 2015. Inpatient general medicine wards in 11 US hospitals, including university-affiliated hospitals and Veterans Affairs medical centers. Participants included 12 exemplary clinician educators, 57 of their current learners, and 26 of their former learners. In-depth, semi-structured interviews of exemplary clinician educators, focus group discussions with their current and former learners, and direct observations of clinical teaching during inpatient rounds. Interview data, focus group data, and observational field notes were coded and categorized into broad, overlapping themes. Each theme elucidated a series of actions, behaviors, and approaches that exemplary clinician educators consistently demonstrated during inpatient rounds: (1) they fostered positive relationships with all team members by building rapport, which in turn created a safe learning environment; (2) they facilitated patient-centered teaching points, modeled excellent clinical exam and communication techniques, and treated patients as partners in their care; and (3) they engaged in coaching and collaboration through facilitation of discussion, effective questioning strategies, and differentiation of learning among team members with varied experience levels. This study identified consistent techniques and behaviors of excellent teaching during inpatient general medicine rounds.

    2014-11-01

    Percutaneous left atrial appendage closure technology for stroke prevention in patients with atrial fibrillation has significantly advanced in the past 2 decades. Several devices are under clinical investigation, and a few have already received Conformité Européene (CE)-mark approval and are available in many countries. The WATCHMAN device (Boston Scientific, Natick, Massachusetts) has the most supportive data and is under evaluation by the U.S. Food and Drug Administration for warfarin-eligible patients. The Amplatzer Cardiac Plug (St. Jude Medical, Plymouth, Minnesota) has a large real-world experience over the past 5 years, and a randomized trial comparing Amplatzer Cardiac Plug with the WATCHMAN device is anticipated in the near future. The Lariat procedure (SentreHEART Inc., Redwood City, California) has also gained interest lately, but early studies were concerning for high rates of serious pericardial effusion and major bleeding. The current real-world experience predominantly involves patients who are not long-term anticoagulation candidates or who are perceived to have high bleeding risks. This pattern of practice is expected to change when the U.S. Food and Drug Administration approves the WATCHMAN device for warfarin-eligible patients. This paper reviews in depth the procedural techniques, safety, and outcomes of the current leading devices. Copyright © 2014 American College of Cardiology Foundation. Published by Elsevier Inc.

    The aim of this study is to describe the procedure technique, clinical and imaging outcomes of patients treated with radiofrequency ablation for chondroblastoma. Four patients (female/male, 3:1; mean age, 13 years; age range; 9-16 years) underwent the procedure. All had pre-operative magnetic resonance imaging (MRI) and symptomatic, biopsy-proven chondroblastomas (two proximal femur, two proximal tibia). The lesion size ranged from 1.5 to 2.5 cm in maximal dimension (mean size, 1.8 cm). Bone access was gained with a Bonopty biopsy needle system (mean number of radiofrequency needle placements, 5; mean ablation time, 31 min). Clinical and MRI follow-up was available in all cases (mean, 12.25 months; range, 5-18 months). All patients reported resolution of symptoms at 2-6 weeks post ablation. At their most recent clinical follow-up, three patients remained completely asymptomatic with full return to normal activities and one patient had minor local discomfort (different pain pattern) that was not limiting activity. All four patients' follow-up MRI studies demonstrated resolution of the oedema pattern around the lesion and temporal evolution of the internal signal characteristics with fatty replacement. Radiofrequency ablation for chondroblastoma provides an alternative to surgical curettage, and we have demonstrated both a clinical improvement in symptoms and the follow-up MRI appearances. (orig.)

    2014-10-01

    Full Text Available The purpose of this study is to determine the methods and techniques science teachers mostly employ in their classrooms. To collect data, the researchers employed a survey with 60 science teachers and randomly selected 6 of them to observe these selected teachers in real classroom situation. Furthermore, the researchers invited 154 students taught by the selected 6 teachers in this study, for focus group interviewing. After analyzing the collected data, the researchers found that teachers in this study 1 were more likely to use narrative method, 2 supported their teaching with question and answer, demonstration, case study, and problem solving methods and techniques, and 3 rarely employed student centered discussion, laboratory practice, role playing and project-based learning methods in their classroom. Consequently, there exist some differences between theory and practice regarding teaching methods and techniques of teachers in this study.

    2013-01-01

    Full Text Available Background: Medical students are expected to master the ability to interpret histopathologic images, a difficult and time-consuming process. A major problem is the issue of transferring information learned from one example of a particular pathology to a new example. Recent advances in cognitive science have identified new approaches to address this problem. Methods: We adapted a new approach for enhancing pattern recognition of basic pathologic processes in skin histopathology images that utilizes perceptual learning techniques, allowing learners to see relevant structure in novel cases along with adaptive learning algorithms that space and sequence different categories (e.g. diagnoses that appear during a learning session based on each learner′s accuracy and response time (RT. We developed a perceptual and adaptive learning module (PALM that utilized 261 unique images of cell injury, inflammation, neoplasia, or normal histology at low and high magnification. Accuracy and RT were tracked and integrated into a "Score" that reflected students rapid recognition of the pathologies and pre- and post-tests were given to assess the effectiveness. Results: Accuracy, RT and Scores significantly improved from the pre- to post-test with Scores showing much greater improvement than accuracy alone. Delayed post-tests with previously unseen cases, given after 6-7 weeks, showed a decline in accuracy relative to the post-test for 1 st -year students, but not significantly so for 2 nd -year students. However, the delayed post-test scores maintained a significant and large improvement relative to those of the pre-test for both 1 st and 2 nd year students suggesting good retention of pattern recognition. Student evaluations were very favorable. Conclusion: A web-based learning module based on the principles of cognitive science showed an evidence for improved recognition of histopathology patterns by medical students.

    To evaluate the teaching and operative techniques for the repair and/or replacement of direct resin-based composite restorations (DCRs) in dental schools in Oceania. A 14-item questionnaire was mailed to the heads of operative dentistry in 16 dental schools in Oceania (Australia, New Zealand, Fiji and Papua New Guinea). The survey asked whether the repair of DCRs was taught within the curriculum; the rationale behind the teaching; how techniques were taught, indications for repair, operative techniques, materials used, patient acceptability, expected longevity and recall systems. All 16 schools participated in the study. Thirteen (81%) reported the teaching of composite repairs as an alternative to replacement. Most schools taught the theoretical and practical aspects of repair at a clinical level only. All 13 schools (100%) agreed on tooth substance preservation being the main reason for teaching repair. The main indications for repair were marginal defects (100%), followed by secondary caries (69%). All 13 schools that performed repairs reported high patient acceptability, and considered it a definitive measure. Only three schools (23%) claimed to have a recall system in place following repair of DCRs. Most respondents either did not know or did not answer when asked about the longevity of DCRs. Repair of DCRs seems to be a viable alternative to replacement, which is actively taught within Oceania. Advantages include it being minimally invasive, preserving tooth structure, and time and money saving. However, standardised guidelines need to be developed and further clinical long-term studies need to be carried out. The decision between replacing or repairing a defective composite restoration tends to be based on what clinicians have been taught, tempered by experience and judgement. This study investigated the current status of teaching and operative techniques of repair of direct composite restorations in dental schools in Oceania. Copyright © 2017 Elsevier Ltd

    Background and study aim: Per oral endoscopic myotomy (POEM) is a complex technique used in achalasia. Preclinical training is essential but little is known about the number of procedures needed. The aim of this study was to determine the number of procedures required to master POEM in an animal model. Patients and methods: This prospective comparative study was conducted in two swine models at a single institution in Mexico City between November 2012 and October 2014: Group 1 (G1) = 30 ex vivo and Group 2 (G2) = 20 live swine models. POEM was mastered after finishing the five steps without complications. Time, characteristics, and complications were recorded. Velocity of tunnelization and myotomy (VTM) was determined. Ex vivo analysis was done in G1 immediately after finishing POEM and at day 30 in G2. Results: A total of 50 POEM were done in both groups (G1 = 30, G2 = 20). The mean times were 90.17 min (G1) and 89.50 min (G2) (P = 0.92). Myotomy was faster in G2 (21.10 vs 27.97 min; P = 0.009) with a slightly slower tunnelization (40.35 vs 41.13 min; P = 0.86). Myotomy was longer in G2 (9.25 vs 8.83 cm; P = 0.26). VTM between the groups was similar (G1 = 0.159 vs G2 = 0.157 cm/min; P = 0.925). Complications were: mucosotomy (G1 = 18 %, G2 = 8 %; P = 0.430), mediastinal perforation (G1 = 12 %, G2 = 8 %; P = 1.0), and perforation at the gastroesophageal junction (GEJ) level (G1 = 16 %, G2 = 4 %; P = 0.149). Seven models in G2 presented minor bleeding and there was one death not attributed to the procedure. Mastery was obtained after 26 cases. Conclusions: We suggest that centers interested in learning POEM consider 26 procedures in animal models to master it before performing it in patients with achalasia. PMID:26716112

    We investigated whether a 3D overlay roadmap using monoplane fluoroscopy offers advantages over a conventional 2D roadmap using biplane fluoroscopy during endovascular aneurysm treatment. A retrospective chart review was conducted for 131 consecutive cerebral aneurysm embolizations by three neurointerventionalists at a single institution. Allowing for a transition period, the periods from January 2012 to August 2012 (Time Period 1) and February 2013 to July 2013 (Time Period 2) were analyzed for radiation exposure, contrast administration, fluoroscopy time, procedure time, angiographic results, and perioperative complications. Two neurointerventionalists (Group 1) used a conventional 2D roadmap for both Time Periods, and one neurointerventionalist (Group 2) transitioned from a 2D roadmap during Time Period 1 to a 3D overlay roadmap during Time Period 2. During Time Period 2, Group 2 demonstrated reduced fluoroscopy time (poverlay roadmap technique reduced fluoroscopy dose and fluoroscopy time during neurointervention of cerebral aneurysms with similar angiographic occlusions and complications rate relative to biplane 2D roadmap, which implies possible compensation of limitations of monoplane fluoroscopy by 3D overlay technique.

    2014-01-01

    Full Text Available Background: Frenectomy is the complete excision of the frenum along with its attachment to the underlying bone. It can be done by conventional technique, electrosurgery or soft tissue lasers. Aim: To evaluate the effects of diode laser and scalpel technique on degree of post-operative pain and discomfort experienced by patients on the 1 st , 3 rd and the 7 th post-operative days after frenectomy. Materials and Methods: Ten patients who required frenectomy were randomly assigned to undergo treatment with diode laser or scalpel. The data were analyzed with paired t-test and intragroup comparison was determined by ANOVA. Results: Intergroup comparison of the mean VAS scores for discomfort and pain for both the groups showed significant difference. The VAS scores of pain and discomfort within scalpel group between 1 st and 3 rd day did not show any significant difference, however between 7 th day versus 3 rd and 1 st day difference was highly significant. The VAS scores of pain and discomfort within laser group between all the days showed significant difference. Conclusion: Taking into consideration the clinical outcome, the diode laser is a dependable alternative as it is an efficient and satisfactory option for procedures like frenectomy.

  10. Organ doses of the cardiologists and their assistants during interventional cardiology procedures at teaching general hospitals in Mashhad/ Iran

    Bahreyni Toosi, M.; Zare, H.; Bayani, Sh.; Esmaili, S. [Mashhad University of Medical Sciences, Medical Physics Dep., Faculty of Medicine, Mashhad (Iran, Islamic Republic of)

    2006-07-01

    Full text of publication follows: Protection of medical personnel in interventional cardiology is now days one of the most important issues of radiological protection. Due to the rapid increase of coronary heart disease in developed and developing countries, application of interventional techniques such as coronary angiography and angioplasty have also increased sharply over past two decades. While these procedures are carried out cardiologists and their assistants are remained close to the patient and within the hot area of the radiation field. Therefore they are subject to receive significant doses of radiation. In this study doses received by critical and more vulnerable organs of cardiologists and their assistants were measured by thermoluminescent dosimeters (T.L.D.). T.L.D. measurements were carried for 115 coronary angiography (C.A.) and 30 pre-cutaneous transluminal coronary angioplasty (P.T.C.A.) procedures at teaching general hospitals in Mashhad-Iran. Doses received by thyroid, gonad, right and left hands of the study groups were measured. For this purpose T.L.D. were placed on and underneath of the lead apron adjacent to gonads and on the wrist of both hands. The results of this study imply that: a) For both groups left hands are subject to receiving the highest mean dose (0.18 mGy/P.T.C.A.) b) Thyroid mean dose per P.T.C.A. received by the T.L.D. chips on the shield is 0.72 mGy and is much higher than corresponding value for the T.L.D. placed underneath the shield. c) Gonads would receive the highest mean dose per P.T.C.A. (0.16 mGy), second to left hand, if lead apron is not worn, but lead apron reduces the dose by a factor of nearly six. d) General speaking assistants, mostly stood on the right side of cardiologists, receive smaller dose. e) P.T.C.A. induces a higher dose to all organs of both cardiologists and their assistants when compared with the corresponding doses arising from C.A. procedure.

    2011-01-01

    Abstract: Since the introduction of the Norwood procedure for surgical palliation of hypoplastic left heart syndrome in 1983, refinements have been made to the original procedure to improve patient outcomes while still accomplishing the original goals of the procedure. One of these refinements has been the introduction of regional selective perfusion to limit the duration of circulatory arrest times and optimize the regional flow distribution. In this paper we describe our technique for performing selective cerebral and lower body perfusion during the Norwood procedure. PMID:22416608

    Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgical procedures to prevent transient urinary tract obstruction and postoperative flank pain from ureteral edema and blood clots. Several restrictive conditions that make this procedure difficult and time consuming, however, include the coiled distal ends of the flexible Double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a Double-J stent insertion method using the new J-tube technique. Between July 2011 and May 2013, Double-J stents were inserted using the J-tube technique in 33 patients who underwent a laparoscopic UUT surgical procedure by a single surgeon. The mean stent placement time was 4.8±2.7 minutes, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for Double-J stent insertion during laparoscopic surgical procedures.

    The deposition of inorganic salts ("scales") such as calcium carbonate is an important flow assurance problem during crude oil production. The knowledge of the features of the precipitated solids, mainly the particle size and morphology, is crucial to understand the nature of the solids and to avoid or reduce the effect of their deposition. For instance, the use of additives is one of the most usual procedures to mitigate this problem. Additives interact with scale-forming substances either by increasing the induction time, or by inhibiting crystal growth, changing the morphology of solids. In this work, CaCO 3 was precipitated by two different experimental methods: by mixing sodium carbonate and calcium chloride at 25 °C (method 1), and by changing the pH (method 2). Precipitated solids were analyzed by means of the following techniques: laser diffraction (LD), focused-beam reflectance measurement (FBRM), scanning electron microscopy (SEM), and X-ray diffraction (XRD), in order to select a method for the determination of particle size of solids similar to scales, in order to study these deposits at the beginning of their formation and to evaluate the effect of additives in the scales particle size. Results were compared to those of scale deposits extracted from crude oil pipelines. SEM and XRD characterization showed that both the precipitation methods lead to calcium carbonate as a mixture of calcite, aragonite and vaterite, with rhombohedral morphology for method 1 and spherical for method 2. The effects of temperature, kinetics and Mg 2+ presence in the morphology of CaCO 3 were evaluated. Thus, the solids obtained by static bottle test and real scales are mainly formed by long needle-shaped aragonite. The comparison of the several particle size characterization methods determinates that an LD is a fast and sensitive technique for spherical and non-spherical solids, and it is a convenient technique for the analysis of scales extracted from oil pipelines.

    Full Text Available PURPOSE: The Schroeder-Essed plication procedure is a standard technique for the correction of penile curvature. In a retrospective analysis we compared functional results and quality of life (LQ of the original technique with inverted sutures as described by Schroeder-Essed and our slight modification consisting of horizontal incisions into the tunica albuginea. MATERIALS AND METHODS: Twenty-six patients with congenital penis deviation were treated for penile deviation by the original Schroeder-Essed plication with inverted sutures (11 patients and by the described modification (15 patients. In case of modified technique, horizontal and parallel incisions 4 mm to 6 mm apart and about 8 mm - 10 mm long were made through the tunica albuginea. The outer edges of the incisions were then approximated with permanent inverted sutures (Gore-Tex® 3-0. Mean age was 21.6 years in the first group and 23.2 years in the second group. Average follow-up was 28 months and 13 months, respectively. The preoperative penile deviation angle was > 25º in all patients without difference between the 2 groups. RESULTS: All patients in both groups reported an improvement in their quality of life and full ability to engage in sexual intercourse. Nine patients (88% in the first group and 14 patients (93% in the second group were satisfied with the cosmetic result. In contrast, 10 patients (91% of the first and 13 patients (87% of the second group complained of penile shorting. Recurrence of deviation was only noticed in 2 males in the first group (18%. CONCLUSIONS: Our results indicate that this simple modification of the Schroeder-Essed plication offers good functional and cosmetic results. Most patients were satisfied with the penile angle correction results.

  17. [Breast augmentation with autologous fat - experience of 96 procedures with the BEAULI-technique].

    Over the past 30 years, interest in the use of autologous fat for aesthetic body contouring, especially for breast augmentation has been continuously on the rise. The benefits of an autologous fat transplant include the absence of any inflammatory reaction to a foreign body, its harmonious appearance and a natural feeling. In earlier years, complications such as necrosis, infections or the formation of cysts, poor resorption rates as well as the difficulty of harvesting large amounts of fat within a reasonable amount of time provided grounds for criticism of the methodology of autologous fat transplantation. With the advent of the so-called BEAULI method, since 2007 a procedure is available for the efficient harvesting and processing of larger quantities of transplantable fat. The aim of the study is to describe the technique in detail and reproducibly and to present a detailed overview of autologous fat transfer due to the basis of our own clinical experience. Between 1 September 2010 and 30 June 2012 the author performed 96 fat transfer procedures on 84 patients. Patients aged 18-60 with a desire for a moderate augmentation of volume and shape of the breasts were selected for the procedure. The fat was harvested using water jet-assisted liposuction (Bodyjet) to flush out the fat cells and subsequent separation of the fat components with the Lipo-Collector. There were no occurrences of post-operative complications in any of the cases. The results were evaluated in the context of a check-up, a photographic comparison and with the completion of a questionnaire. With regard to the increase in size and/or shape enhancement of the breasts, 31% of the patients were very happy with the results, 45% indicated they were satisfied, 23% would have liked more volume, while 1% were dissatisfied. This study indicates that the autologous fat transplant into the female breast using the BEAULI method represents an excellent, safe method for the achievement of a moderate and

    The aim of this study was to evaluate the influence of 2 different surface polishing procedures-glazing and manual polishing-on the roughness of ceramics processed by computer-aided design/computer-aided manufacturing (CAD/CAM) and conventional systems (stratification technique). Eighty ceramic discs (diameter: 8 mm, thickness: 1 mm) were prepared and divided among 8 groups (n = 10) according to the type of ceramic disc and polishing method: 4 GZ and 4 MP. Specimens were glazed according to each manufacturer's recommendations. Two silicone polishing points were used on the ceramic surface for manual polishing. Roughness was measured using a surface roughness tester. The roughness measurements were made along a distance of 2 mm on the sample surface and the speed of reading was 0.1 mm/s. Three measurements were taken for each sample. The data (μm) were statistically analyzed using analysis of variance (ANOVA) and Tukey's test (α = 0.05). Qualitative analysis was performed using scanning electron microscopy (SEM). The mean (± SD) roughness values obtained for GZ were: 1.1 ± 0.40 μm; 1.0 ± 0.31 μm; 1.6 ± 0.31 μm; and 2.2 ± 0.73 μm. For MP, the mean values were: 0.66 ± 0.13 μm; 0.43 ± 0.14 μm; 1.6 ± 0.55 μm; and 2.0 ± 0.63 μm. The mean roughness values were significantly affected by the ceramic type (P = 0.0001) and polishing technique (P = 0.0047). The SEM images confirmed the roughness data. The manually polished glass CAD/CAM ceramics promoted lower surface roughness than did the glazed feldspathic dental ceramics.

  19. Legal, ethical, and procedural bases for the use of aseptic techniques to implant electronic devices

    Mulcahy, Daniel M.

    2013-01-01

    The popularity of implanting electronic devices such as transmitters and data loggers into captive and free-ranging animals has increased greatly in the past two decades. The devices have become smaller, more reliable, and more capable (Printz 2004; Wilson and Gifford 2005; Metcalfe et al. 2012). Compared with externally mounted devices, implanted devices are largely invisible to external viewers such as tourists and predators; exist in a physically protected, thermally stable environment in mammals and birds; and greatly reduce drag and risk of entanglement. An implanted animal does not outgrow its device or attachment method as can happen with collars and harnesses, which allows young animals to be more safely equipped. However, compared with mounting external devices, implantation requires greater technical ability to perform the necessary anesthesia, analgesia, and surgery. More than 83% of publications in the 1990s that used radiotelemetry on animals assumed that there were no adverse effects on the animal (Godfrey and Bryant 2003). It is likely that some studies using implanted electronic devices have not been published due to a high level of unexpected mortality or to aberrant behavior or disappearance of the implanted animals, a phenomenon known as the “file drawer” problem (Rosenthal 1979; Scargle 2000). The near absence of such studies from the published record may be providing a false sense of security that procedures being used are more innocuous than they actually are. Similarly, authors sometimes state that it was unlikely that device implantation was problematic because study animals appeared to behave normally, or authors state that previous investigators used the same technique and saw no problems. Such statements are suppositions if no supporting data are provided or if the animals were equipped because there was no other way to follow their activity. Moreover, such suppositions ignore other adverse effects that affect behavior indirectly, and

    2008-01-01

    Full Text Available The coupling of groundwater movement and reactive transport during groundwater recharge with wastewater leads to a complicated mathematical model, involving terms to describe convection-dispersion, adsorption/desorption and/or biodegradation, and so forth. It has been found very difficult to solve such a coupled model either analytically or numerically. The present study adopts operator-splitting techniques to decompose the coupled model into two submodels with different intrinsic characteristics. By applying an upwind finite difference scheme to the finite volume integral of the convection flux term, an implicit solution procedure is derived to solve the convection-dominant equation. The dispersion term is discretized in a standard central-difference scheme while the dispersion-dominant equation is solved using either the preconditioned Jacobi conjugate gradient (PJCG method or Thomas method based on local-one-dimensional scheme. The solution method proposed in this study is applied to the demonstration project of groundwater recharge with secondary effluent at Gaobeidian sewage treatment plant (STP successfully.

    To assess the learning process of combining a web-based video of a simulated surgical procedure with a step-by-step checklist of the same procedure in achieving competency of the simulated technique, in this case a newborn clamp circumcision. Fundamental to this particular learning process is immediate mentor step-by-step feedback which specifically follows the procedure's step-by-step checklist. Pediatric residents naïve to newborn circumcision were enrolled (n = 7). A circumcision simulator, instruments, and web access to the learning module were provided. Residents trained independently and then performed two simulations with the mentor. The first simulation was completed with formative scored feedback. The learner then performed a second scored simulation. All learners showed improvement between the first and second simulation (mean 85.3-97.4). All residents achieved competency (96/100 or greater) by the second simulation. On post-procedure surveys, learners demonstrated increased comfort and reduced apprehension in performing the procedure. Combining a web-accessible video of a procedure, a checklist, and a simulator followed by a single mentor session with immediate formative feedback which follows the steps of the checklist is a useful method to teach the simulation technique of circumcision. We plan to study if this paradigm is transferable to clinical circumcision. Copyright © 2013 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

    Cancer health disparities are a reality for Hmong women who are often diagnosed at a later stage and have low literacy and experienced care that are not culturally appropriate. Lack of attention to cultural appropriateness and literacy levels of cancer screening materials may contribute to disproportionately low levels of cancer screening among Hmong women. The purposes of this study were to evaluate the Hmong Health Awareness Project (HHAP), a program designed to create awareness and acceptance of breast and cervical cancer screening, and to examine participants' perceptions of the utility of the content of the workshops. Hmong researchers partnered with three Midwestern Hmong community centers to implement six workshops. Three teaching techniques: pictographs, videos, and hands-on activities were utilized to teach Hmong participants about cancer screening. Participants included 150 Hmong (male participants = 30 and female participants = 120). Teach-back method was used to assess the participants' understanding of cancer screening throughout the workshops. Qualitative data were collected in focus groups to assess the feasibility of teaching methods and participants' perceptions of the utility of the content of the workshops. Directed content analysis was used to analyze participants' responses. The three teaching techniques were helpful in increasing the Hmong people's understanding about breast and cervical cancer screening. Nearly, all participants perceived an increased in their understanding, greater acceptance of cancer screening, and increased willingness to be screened. Men expressed support for screening after the workshops. Findings can guide future interventions to improve health communications and screening and reduce diagnostic disparities among Hmong and immigrant populations.

    Water jet dissection represents a promising technique for precise brain tissue dissection with preservation of blood vessels. In the past, the water jet dissector has been used for various pathologies. A detailed report of the surgical technique is lacking. The authors present their results after 208 procedures with a special focus on surgical technique, intraoperative suitability, advantages, and disadvantages. Between March 1997 and April 2009, 208 patients with various intracranial neurosurgical pathologies were operated on with the water jet dissector. Handling of the device and its usefulness and extent of application were assessed. The pressures encountered, potential risks, and complications were documented. The patients were followed 1 to 24 months postoperatively. A detailed presentation of the surgical technique is given. Differences and limitations of the water jet dissection device in the various pathologies were evaluated. The water jet dissector was intensively used in 127 procedures (61.1%), intermittently used in 56 procedures (26.9%), and scarcely used in 25 procedures (12%). The device was considered to be very helpful in 166 procedures (79.8%) and helpful to some extent in 33 procedures (15.9%). In 8 (3.8%) procedures, it was not helpful, and in 1 procedure (0.5%), the usefulness was not documented by the surgeon. The water jet dissector can be applied easily and very safely. Precise tissue dissection with preservation of blood vessels and no greater risk of complications are possible. However, the clinical consequences of the described qualities need to be demonstrated in a randomized clinical trial.

    The aim of this randomized controlled study was to compare ultrasound-guided procedure with the Seldinger's technique for placement of implantable venous ports. A total of 214 patients were randomized to receive TIAP placement by either ultrasound-guided procedure or the Seldinger's technique. Complications and pain perception were compared between these two groups. No severe perioperative or periinterventional complication occurred. Significantly (P venous thrombosis, fever of unknown origin, skin necrosis, and sepsis. In conclusion, both techniques, the TIAP implantation via ultrasound-guided jugular vein puncture and via Seldinger's technique subclavian vein puncture, are feasible and safe. Regarding intrainterventional pain perception and implantation-related complications, the jugular vein puncture under ultrasound guidance seems to be advantageous.

    Despite growth in placement of retrievable inferior vena cava filters, retrieval rates remain low. Filters with extended implantation times present a challenge to retrieval, where standard techniques often fail. The development of advanced retrieval techniques has positively impacted retrieval of retrievable inferior vena cava filters with prolonged dwell times; however, there is no precise definition of the time point when advanced techniques become necessary. We aim to define prolonged retrievable inferior vena cava filters dwell time by determining the inflection point when the risk of standard retrieval technique failure increases significantly, necessitating advanced retrieval techniques to maintain overall technical success of retrieval. From January 2009 to April 2015, 762 retrieval procedures were identified from a prospectively acquired database. We assessed patient age/sex, filter dwell time, procedural technical success, the use of advanced techniques, and procedure-related adverse events. Overall retrieval success rate was 98% (n=745). When standard retrieval techniques failed, advanced techniques were used; this was necessary 18% of the time (n=138). Logistic regression identified that dwell time was the only risk factor for failure of standard retrieval technique (odds ratio, 1.08; 95% confidence interval, 1.05-1.10; Ptechnique failure was 40.9%. Adverse events occurred at a rate of 2% (n=18; 15 minor and 3 major). The necessity of advanced techniques to maintain technical success of retrieval increases with dwell time. Patients with retrievable inferior vena cava filters in place beyond 7 months may benefit from referral to centers with expertise in advanced filter retrieval. © 2017 American Heart Association, Inc.

    Full Text Available Objective: To evaluate and compare the pain perception by the pediatric patients, while experiencing computerized injection device comfort control syringe (CCS and the conventional injection technique during dental clinical procedures. Materials and Methods: Fifty children (31 boys and 19 girls aged 6-14 years requiring local anaesthesia on both sides of the dental arch for various treatment procedures were selected for this study. The patients served as their own control, and on the appointed day CCS was used on one side of the dental arch and on the subsequent appointment, i.e., the very next day conventional injection technique was used. Visual analogue scale (VAS and faces pain rating scale (FRS were used to assess the child′s pain perception to each of the techniques immediately after the injection. Various physiological parameters were measured before, during and after the two injection procedures and compared for statistical variation. Results : Paired t-test revealed a statistically significant difference in the pain perception by children using VAS and FRS between computerized and conventional technique. No statistically significant difference was observed when physiological parameters (heart rate, blood pressure and temperature were compared at various intervals between the computerized and the conventional technique. Conclusion: Computerized injection device (CCS provides less painful injections when compared to the conventional injection technique.

    Based on systematic reviews, it appears that at least 10% of patients may continue to suffer with residual or persistent pain after successful vertebral or sacral augmentation procedures. To report and evaluate the incidence and prevalence of different spinal injections in patients who received vertebroplasty, kyphoplasty, and sacroplasty procedures for both benign and malignant compression fractures. A retrospective case review. Retrospective review of all cases of vertebroplasty, sacroplasty, and kyphoplasty performed in a 12-month period in a single outpatient setting of interventional radiology was conducted. In a 12-month period starting from October 2005 to September 2006, 144 patients underwent cement augmentation procedures. Of the 144, 34 patients required a spinal injection procedure for residual or persistent pain within a 1-year period after the augmentation procedure. Twenty-four patients required epidural steroid injections, 6 patients required intercostal nerve blocks, 5 patients required trigger point injections, 5 patients required sacroiliac joint injections, and 1 patient required facet joint injections. Nine patients who required lumbar epidural steroid injections and all patients who required intercostal nerve blocks and had underwent a thoracic cement augmentation procedure. A small proportion of patients undergoing percutaneous cement augmentation for vertebral compression fractures or sacral insufficiency fractures potentially require spinal injections to treat residual pain after the procedure.

    Recurrent shoulder instability is commonly associated with glenoid bone defects. Coracoid transfer procedures, such as the Bristow and Latarjet procedures, are frequently used to address these bone deficiencies. Despite the frequent synonymous labeling of these transfers as the "Bristow-Latarjet" procedure, their true equivalence has not been demonstrated. Therefore, our purpose was to compare the biomechanical effects of these two procedures. Eight cadaveric specimens were tested on a custom shoulder simulator capable of loading nine muscle groups and of accurately orienting the joint throughout shoulder motion. The specimens were tested in the intact state, following Bristow and Latarjet reconstructions of a capsulolabral injury (0% glenoid defect), and following each procedure after creation of 15% and 30% glenoid bone defects. The reconstruction order was randomized. In each condition, joint stiffness (anterior stability) and occurrence of dislocation were assessed in shoulder adduction and abduction with neutral and external rotation. No significant differences (p Latarjet reconstructions for the 0% glenoid defect in any joint position. However, substantially greater joint stiffness occurred following the Latarjet procedure, as compared with the Bristow procedure, for the 15% and 30% glenoid bone-loss conditions in adduction with neutral rotation, adduction with external rotation, and abduction with external rotation (average across the three joint positions: 8.6 ± 4.4 N/mm versus 3.9 ± 1.26.7 N/mm [p = 0.034] with 15% bone loss and 7.5 ± 4.4 N/mm versus 3.4 ± 1.5 N/mm [p = 0.045] with 30% bone loss). The Latarjet reconstruction restored the stiffness that had been measured in the intact state in eleven of the twelve tested conditions, whereas the Bristow procedure was successful in only four of the twelve conditions. In addition, during instability testing, three more specimens dislocated following the Bristow reconstruction, compared with the Latarjet

    2007-03-01

    The Sauvé-Kapandji procedure has been commonly performed in the setting of posttraumatic osteoarthritis of the distal radioulnar joint. A recognized complication is instability of the proximal ulnar stump, which may occur in up to 33% of cases. Salvage of the failed Sauvé-Kapandji procedure in this setting is difficult and can sometimes involve sacrifice of forearm rotation. We report the results of 3 cases of a new salvage procedure in this setting. The radioulnar pseudarthrosis was taken down; ulnar continuity was restored with an intercalary graft; and forearm rotation was restored with matched hemiresection and interposition arthroplasty at the site of previous radioulnar fusion. Postoperatively, all patients achieved good forearm rotation (mean supination, 60 degrees; mean pronation, 65 degrees), had no symptoms of instability, and were satisfied with the results of the procedure. Disabilities of the Arm, Shoulder and Hand scores improved from preoperative mean of 55 to postoperative mean of 18.

    2005-03-01

    Percutaneous placement of large-diameter dialysis catheters via the Seldinger technique can be technically challenging in patients with coagulopathy, difficult anatomy, or several previous central line insertions. We describe a method for achieving safer access by combining an open approach to delineate the venous anatomy of the chest wall, with a micropuncture device and smaller diameter guidewire to gain intravascular access to the cephalic vein or its major tributaries. Serial dilation of otherwise unusable vessels can then permit successful and safer hemodialysis catheter insertion in these difficult cases.

    Full Text Available Among three sections that follow the Paper-Based TOEFL (PBT, many test takers find listening comprehension section is the most difficult. Thus, in this research the researcher aims to explore how students learn PBT’s listening comprehension section effectively through song technique. This sounds like a more interesting and engaging way to learn language because music is a very powerful motivational tool for learning language. To reach the goal of this study, the researcher applied the grammar approach. It is an appropriate approach since the main idea of grammar-based listening exercises is to analyze the language by its components and reconstruct an incomplete text. Besides, the researcher employed an English song as the media the researcher uses the top- down model for the Listening Process.  In this research, the writer tries to share his experience in teaching listening in English department of Teknokrat College by implementing song technique.

    Full Text Available BACKGROUND: Ganglion is one of the commonly seen lesions in minor surgical practice. Treatment of wrist ganglia includes simple reassurance, watchful waiting, non-operative aspiration, injection, surgical excision and even sometimes advanced endoscopic excision. Although treatment is not often necessary, many patients seeking consultation ask for some form of definitive treatment. High incidence of recurrence is seen with cyst aspiration/injection or after surgical excision. Recurrence is the common problem, irrespective of the treatment modality. MATERIALS AND METHODS: This study evaluates results of a modified minimally invasive surgical technique used for the management of ganglia of the wrist. Thirty six wrist ganglia have been treated by using the transfixation technique. RESULTS: The successful results for the procedure were seen in 94.44% patients. Consequent to the procedure, an average of 2days off work were lost. Recurrence in the 2 year follow-up was seen in two patients. DISCUSSION: On comparing with other modalities this method is minimally invasive, cost-effective, less time consuming, low rate of recurrence and at the same time can be carried out under local anesthesia as a day case procedure and even not requiring any specific instrument and further this technique can be easily learned.

    Thoracic surgical procedures can be either thoracotomy or thoracoscopy. In thoracotomy, the incision could be either muscle-cutting or muscle-sparing incision. The posterolateral thoracotomy incision is used for most general thoracic surgical procedures. This incision, which involves division of the latissimus dorsi and serratus anterior muscles, affords excellent exposure of the thoracic cavity. However, it is associated with significant morbidity, including impaired pulmonary function, postoperative chest pain, and restricted arm and shoulder movement. Various muscle-sparing incisions have been proposed to decrease the morbidity. Postthoracotomy pain originates from pleural and muscular damage, costovertebral joint disruption, and intercostal nerve damage during surgery. Inadequate pain relief after surgery affects the quality of patient's recovery and exposes the patients to postoperative morbidities. There is a tendency nowadays among thoracic surgeons and anesthesiologists toward the area of enhanced recovery after thoracic surgery which requires careful titration of the anesthetic drugs in awake patients undergoing thoracoscopic procedures. There is a common feeling among thoracic anesthesiologists that potthoracoscopy procedures produce less pain intensity versus thoracotomy which is partially true. However, effective management of acute pain following either thoracotomy/thoracoscopy is needed and may prevent these complications and reduce the likelihood of developing chronic pain. In this report, we are going to review the newly introduced postthoracotomy/thoracoscopy pain relief modalities with special reference to the new tendency of awake thoracic surgical procedures and its impact on enhanced recovery after surgery.

    Robot-assisted laparoscopic surgery is often taught with the surgical mentor at the surgeon console and the trainee at the patient's bedside. The da Vinci dual console (Intuitive Surgical, Sunnyvale, California) allows a surgical mentor to teach with both the mentor and the trainee working at a surgeon console simultaneously. The purpose of this study is to evaluate the effectiveness of the dual console versus the single console for teaching medical students robotic tasks. Forty novice medical students were randomized to either the da Vinci single-console or dual-console group and were taught 4 knot-tying techniques by a surgical mentor. The students were timed while performing the tasks. No statistically significant differences in mean task times were observed between the single- and dual-console groups: interrupted stitch with a 2-handed knot (300 seconds for single vs 294 seconds for dual, P=.59), interrupted stitch with a 1-handed knot (198 seconds for single vs 212 seconds for dual, P=.88), figure-of-8 stitch with a 2-handed knot (261 seconds for single vs 219 seconds for dual, P=.20), and figure-of-8 stitch with a 1-handed knot (200 seconds for single vs 199 seconds for dual, P=.53). No significant difference was observed in performance time when teaching knot-tying techniques to medical students using the da Vinci dual console compared with the single console. More research needs to be performed on the utility of the da Vinci dual console in surgical training.

    The objectives of this prospective randomized trial were to assess the impact of Peyton's four-step approach on the acquisition of complex psychomotor skills and to examine the influence of gender on learning outcomes. We randomly assigned 95 third to fifth year medical students to an intervention group which received instructions according to Peyton (PG) or a control group, which received conventional teaching (CG). Both groups attended four sessions on the principles of manual therapy and specific manipulative and diagnostic techniques for the spine. We assessed differences in theoretical knowledge (multiple choice (MC) exam) and practical skills (Objective Structured Practical Examination (OSPE)) with respect to type of intervention and gender. Participants took a second OSPE 6 months after completion of the course. There were no differences between groups with respect to the MC exam. Students in the PG group scored significantly higher in the OSPE. Gender had no additional impact. Results of the second OSPE showed a significant decline in competency regardless of gender and type of intervention. Peyton's approach is superior to standard instruction for teaching complex spinal manipulation skills regardless of gender. Skills retention was equally low for both techniques.

    The authors present a prospective, randomized, blinded trial comparing the educational efficacy of digital animation versus a textbook in teaching the Ivy loop technique to novice learners. Medical student volunteers (n = 32) were anonymously videotaped as they fastened dental wire to the teeth of a skull model (preintervention analysis) and then were randomly assigned to one of two study groups. The animation and text groups (n = 16 each) were shown either a digital animation or textbook demonstrating the Ivy loop surgical technique. Volunteers were then videotaped as they performed the technique (postintervention analysis). Volunteers were then shown the educational material provided to the other study group and given a validated educational survey to compare the educational value of both materials. Preintervention and postintervention video recordings were graded using a validated surgical competency scale. Surgical performance grades, time to task completion, and educational survey scores were compared. Preintervention analysis performance scores did not significantly differ between the animation and text groups (10.7 [2.8] versus 11.1 [3.9]; p = 0.74), but postintervention analysis demonstrated significantly higher performance scores in the animation group (18.8 [2.9] versus 13.0 [3.5]; p technique. Test takers found digital animation to be the superior educational medium.

    One of the reason for Latarjet procedure failure may be coracoid graft osteolysis. In this study, we aimed to understand if a better compression between the coracoid process and the glenoid, using a mini-plate fixation during the Latarjet procedure, could reduce the amount of coracoid graft osteolysis. A computed tomography scan analysis of 26 prospectively followed-up patients was conducted after modified Latarjet procedure using mini-plate fixation technique to determine both the location and the amount of coracoid graft osteolysis in them. We then compared our current results with results from that of our previous study without using mini-plate fixation to determine if there is any statistical significant difference in terms of corcacoid bone graft osteolysis between the two surgical techniques. The most relevant osteolysis was represented by the superficial part of the proximal coracoid, whereas the deep part of the proximal coracoid graft is least involved in osteolysis and has best bone healing. The current study showed a significant difference only for the deep part of the distal coracoid with our previous study (P Latarjet procedure. Our study suggests that there is a significant difference only for the deep part of the distal coracoid in terms of osteolysis. At clinical examination, this difference did not correspond with any clinical findings. Level 4. Prospective case series, Treatment study.

    Full Text Available Objectives: The Residency Review Committee training requirements for emergency medicine residents (EM are defined by consensus panels, with specific topics abstracted from lists of patient complaints and diagnostic codes. The relevance of specific curricular topics to actual practice has not been studied. We compared residency graduates’ self-assessed preparation during training to importance in practice for a variety of EM procedural skills.Methods: We distributed a web-based survey to all graduates of the Denver Health Residency Program in EM over the past 10 years. The survey addressed: practice type and patient census; years of experience; additional procedural training beyond residency; and confidence, preparation, and importance in practice for 12 procedures (extensor tendon repair, transvenous pacing, lumbar puncture, applanation tonometry, arterial line placement, anoscopy, CT scan interpretation, diagnostic peritoneal lavage, slit lamp usage, ultrasonography, compartment pressure measurement and procedural sedation. For each skill, preparation and importance were measured on four-point Likert scales. We compared mean preparation and importance scores using paired sample t-tests, to identify areas of under- or over-preparation.Results: Seventy-four residency graduates (59% of those eligible completed the survey. There were significant discrepancies between importance in practice and preparation during residency for eight of the 12 skills. Under-preparation was significant for transvenous pacing, CT scan interpretation, slit lamp examinations and procedural sedation. Over-preparation was significant for extensor tendon repair, arterial line placement, peritoneal lavage and ultrasonography. There were strong correlations (r>0.3 between preparation during residency and confidence for 10 of the 12 procedural skills, suggesting a high degree of internal consistency for the survey.Conclusions: Practicing emergency physicians may be uniquely

    To develop a procedure specific global rating scale for assessment of operator competence in endovascular aortic repair (EVAR). A Delphi approach was used to achieve expert consensus. A panel of 32 international experts (median 300 EVAR procedures, range 200-3000) from vascular surgery (n = 21) and radiology (n = 11) was established. The first Delphi round was based on a review of endovascular skills assessment papers, stent graft instructions for use, and structured interviews. It led to a primary pool of 83 items that were formulated as global rating scale items with tentative anchors. Iterative Delphi rounds were executed. The panellists rated the importance of each item on a 5 point Likert scale. Consensus was defined as 80% of the panel rating an item 4 or 5 in the primary round and 90% in subsequent rounds. Consensus on the final assessment tool was defined as Cronbach's alpha > .8 after a minimum of three rounds. Thirty-two of 35 invited experts participated. Three rounds of surveys were completed with a completion rate of 100% in the first two rounds and 91% in round three. The 83 primary assessment items were supplemented with five items suggested by the panel and reduced to seven pivotal assessment items that reached consensus, Cronbach's alpha = 0.82. The seven item rating scale covers key elements of competence in EVAR stent placement and deployment. Each item has well defined grades with explicit anchors at unacceptable, acceptable, and superior performance on a 5 point Likert scale. The Delphi methodology allowed for international consensus on a new procedure specific global rating scale for assessment of competence in EVAR. The resulting scale, EndoVascular Aortic Repair Assessment of Technical Expertise (EVARATE), represents key elements in the procedure. EVARATE constitutes an assessment tool for providing structured feedback to endovascular operators in training. Copyright © 2017 European Society for Vascular Surgery. Published by Elsevier

    The CMS offline computing system is composed of roughly 80 sites (including most experienced T3s) and a number of central services to distribute, process and analyze data worldwide. A high level of stability and reliability is required from the underlying infrastructure and services, partially covered by local or automated monitoring and alarming systems such as Lemon and SLS; the former collects metrics from sensors installed on computing nodes and triggers alarms when values are out of range, the latter measures the quality of service and warns managers when service is affected. CMS has established computing shift procedures with personnel operating worldwide from remote Computing Centers, under the supervision of the Computing Run Coordinator at CERN. This dedicated 24/7 computing shift personnel is contributing to detect and react timely on any unexpected error and hence ensure that CMS workflows are carried out efficiently and in a sustained manner. Synergy among all the involved actors is exploited to ensure the 24/7 monitoring, alarming and troubleshooting of the CMS computing sites and services. We review the deployment of the monitoring and alarming procedures, and report on the experience gained throughout the first two years of LHC operation. We describe the efficiency of the communication tools employed, the coherent monitoring framework, the proactive alarming systems and the proficient troubleshooting procedures that helped the CMS Computing facilities and infrastructure to operate at high reliability levels.

    Current algorithms for decision making in proximal humerus fractures consider the fracture pattern along with the patient characteristics and surgeon’s experience. Minimally invasive techniques for reduction and internal fixation of many types of these fractures have recently been widely promoted, especially with the use of the newly developed locking plate systems. Intramedullary flexible nailing is one of the oldest techniques using minimally invasive reduction and fixation of proximal humerus fractures. Kapandji technique uses the “Deltoid V” landmark as entry point for intramedullary insertion of the flexible nails into the humeral head. The authors report their experience with this procedure in twenty-six, relatively young patients with good bone quality, presenting with displaced 2- or 3-part extra-articular fracture of the proximal humerus, treated with percutaneous reduction and intramedullary flexible nailing as described by Kapandji. Nineteen medical records were available for this retrospective review, with 9 to 12 months follow-up. There were 15 excellent and 1 good results when patients were assessed for pain, function and range of motion of the shoulder. The authors submit that Kapandji technique is a valuable procedure for management of extra-articular displaced 2- and 3- part proximal humerus fractures in young patients with good bone quality.

    Full Text Available This study was conducted to test the effectiveness of modular approach using decision tree in teaching integration techniques in Calculus. It sought answer to the question: Is there a significant difference between the mean scores of two groups of students in their quizzes on (1 integration by parts and (2 integration by trigonometric transformation? Twenty-eight second year B.S. Computer Science students at City College of Calamba who were enrolled in Mathematical Analysis II for the second semester of school year 2013-2014 were purposively chosen as respondents. The study made use of the non-equivalent control group posttest-only design of quasi-experimental research. The experimental group was taught using modular approach while the comparison group was exposed to traditional instruction. The research instruments used were two twenty-item multiple-choice-type quizzes. Statistical treatment used the mean, standard deviation, Shapiro-Wilk test for normality, twotailed t-test for independent samples, and Mann-Whitney U-test. The findings led to the conclusion that both modular and traditional instructions were equally effective in facilitating the learning of integration by parts. The other result revealed that the use of modular approach utilizing decision tree in teaching integration by trigonometric transformation was more effective than the traditional method.

    The Sauvé-Kapandji procedure has become popular for the treatment of disorders of the distal radioulnar joint in patients with rheumatoid arthritis, but this procedure is impossible to perform in patients with poor bone quality in the distal part of the ulna. We have modified the procedure for patients with poor bone quality in the distal part of the ulna. The modified procedure involves resecting the distal part of the ulna, making a drill-hole in the ulnar cortex of the distal part of the radius, rotating the resected portion of the ulna 90 degrees, inserting it into the distal part of the radius, and fixing it at that site with use of an AO cancellous-bone screw. In the present report, we describe the new operative technique and report the results after a minimum duration of follow-up of three years. This operation was performed in fifty-six patients (sixty-six wrists) with rheumatoid arthritis. The mean age at the time of the operation was 59.3 years. The mean duration of follow-up was forty-eight months. Patients were evaluated in terms of wrist pain, grip strength, and range of motion. Radiographic evaluation included calculation of the carpal translation index to assess the extent of ulnar translation of the carpus. Osseous union was achieved in all cases. Wrist pain resolved or decreased in all patients. The mean total range of forearm rotation increased from 144 degrees preoperatively to 167 degrees at the time of the most recent follow-up (p Kapandji procedure results in rigid fixation of the grafted bone. The technique provides sufficient osseous support of the carpus even in patients with rheumatoid arthritis and poor bone quality in the distal part of the ulna.

    Teaching 12-lead electrocardiogram (ECG) interpretation to students and residents is a challenge for medical educators. To date, few studies have compared the effectiveness of different techniques used for ECG teaching. This study aimed to determine if common teaching techniques, such as those involving workshops, lectures and self-directed learning (SDL), increase medical students' ability to correctly interpret ECGs. It also aimed to compare the effectiveness of these formats.   This was a prospective randomised study conducted over a 28-month period. Year 4 medical students were randomised to receive teaching in ECG interpretation using one of three teaching formats: workshop, lecture or SDL. All three formats covered the same content. Students were administered three tests: a pre-test (before teaching); a post-test (immediately after teaching), and a retention test (1 week after teaching). Each tested the same content using 25 questions worth 1 point each. A mixed-model repeated-measures analysis of variance (anova) with least squares post hoc analysis was conducted to determine if differences in test scores between the formats were statistically significant. Of the 223 students for whom data were analysed, 79 were randomised to a workshop, 82 to a lecture-based format and 62 to SDL. All three teaching formats resulted in a statistically significant improvement in individual test scores (p < 0.001). Comparison of the lecture- and workshop-based formats demonstrated no difference in test scores (marginal mean [MM] for both formats = 12.4, 95% confidence interval [95% CI] 11.7-13.2]; p = 0.99). Test scores of students using SDL (MM = 10.7, 95% CI 9.8-11.5) were lower than those of students in the workshop (p = 0.003) and lecture (p = 0.002) groups. Compared with those taught using workshop- and lecture-based formats, medical students learning ECG interpretation by SDL had lower test scores. © Blackwell Publishing Ltd 2011.

    2015-06-01

    Anesthesia providers in low-income countries may infrequently provide regional anesthesia techniques for obstetrics due to insufficient training and supplies, limited manpower, and a lack of perceived need. In 2007, Kybele, Inc. began a 5-year collaboration in Ghana to improve obstetric anesthesia services. A program was designed to teach spinal anesthesia for cesarean delivery and spinal labor analgesia at Ridge Regional Hospital, Accra, the second largest obstetric unit in Ghana. The use of spinal anesthesia for cesarean delivery increased significantly from 6% in 2006 to 89% in 2009. By 2012, >90% of cesarean deliveries were conducted with spinal anesthesia, despite a doubling of the number performed. A trial of spinal labor analgesia was assessed in a small cohort of parturients with minimal complications; however, protocol deviations were observed. Although subsequent efforts to provide spinal analgesia in the labor ward were hampered by anesthesia provider shortages, spinal anesthesia for cesarean delivery proved to be practical and sustainable.

    Many deaf children have great difficulty learning how to use irregular English verbs. This research study seeks to exemplify how a single-case, ABA design can be used by classroom teachers in making a determination about the usefulness of classroom teaching strategies, and in the case of this study, to explore the use of compact language drills (CLDs) as a technique for helping a deaf child improve his ability to use 4 irregular verbs. The CLDs were conducted 5-10 minutes each day for five weeks at the close of school. The drills engaged the child in immediate recall of simple sentences loaded with semantic/syntactic clues which signalled the need for a past, present or future irregular verb within the target sentence. The results suggest that CLDs, when used systematically, can significantly improve a child's ability to use irregular verbs correctly, both immediately following treatment, and across time.

    Determining the rheologic properties of coarse- grained mass flows is an important step to mathematically simulate potential inundation zones. Using the vertically rotating flume designed and built by the U.S. Geological Survey, laboratory procedures and subsequent data reduction have been developed to estimate shear stresses and strain rates of various flow materials. Although direct measurement of shear stress and strain rate currently (1992) are not possible in the vertically rotating flume, methods were derived to estimate these values from measurements of flow geometry, surface velocity, and flume velocity.

    Tularaemia is a severe bacterial zoonosis caused by the highly infectious agent Francisella tularensis. It is endemic in countries of the northern hemisphere ranging from North America to Europe, Asia and Japan. Very recently, Francisella-like strains causing disease in humans were described from tropical northern Australia. In the last decade, efforts have been made to develop sensitive and specific immunological and molecular techniques for the laboratory diagnosis of tularaemia and also for the definite identification of members of the species F. tularensis and its four subspecies. Screening for the keyword 'Francisella' a Medline search over the last decade was performed and articles describing diagnostic methods for tularaemia and its causative agent were selected. Besides classical microbiological techniques (cultivation, biochemical profiling, susceptibility testing) several new immunological and molecular approaches to identify F. tularensis have been introduced employing highly specific antibodies and various polymerase chain reaction (PCR)-based methods. Whereas direct antigen detection by enzyme-linked immunosorbent assay (ELISA) or immunofluorescence might allow early presumptive diagnosis of tularaemia, these methods--like all PCR techniques--still await further evaluation. Therefore, diagnosis of tularaemia still relies mainly on the demonstration of specific antibodies in the host. ELISA and immunoblot methods started to replace the standard tube or micro-agglutination assays. However, the diagnostic value of antibody detection in the very early clinical phase of tularaemia is limited. Francisella tularensis is regarded as a 'highest priority' biological agent (category 'A' according to the CDC, Atlanta, GA, USA), thus rapid and reliable diagnosis of tularaemia is required not only for a timely onset of therapy, the handling of outbreak investigations but also for the surveillance of endemic foci. Only very recently, evaluated test kits for

    2017-03-01

    Second-year dental students are commonly instructed on the process of complete denture fabrication with a traditional didactic lecture and preclinical dental laboratory education model. The problem with this limited mode of instruction is that dental students often fail to understand the various chairside procedures required to fabricate a complete denture. The aim of this study was to investigate the use of standardized dental patients to enhance students' understanding of the procedures involved with each appointment in the complete denture process. The Midwestern University College of Dental Medicine-Arizona created an event using standardized patients in four simulated chairside dental appointments for complete denture instruction of second-year dental students. Each appointment simulated the various sequential chairside procedures required to fabricate complete dentures. Following the didactic and dental laboratory instruction and the standardized patient event, a survey was conducted requesting the students' response to six statements regarding their understanding of the denture fabrication process. Of the 110 students who participated in the instructional events, 107 responded to the survey (97% response rate). These students responded very favorably to the simulated appointments, with the majority agreeing or strongly agreeing that their best understanding of the complete denture process was obtained through the standardized patient experiences. The use of standardized patients in simulated denture fabrication appointments enhanced the educational experience of these students when added to the traditional didactic lecture and preclinical laboratory education format. The experience has since been incorporated into the school's second-year oral health science laboratory curriculum.

    Advances of composite systems and their application have revolutionised the management of posterior teeth affected by caries, facilitating a minimally invasive approach. Previous surveys have indicated that the teaching of posterior composites within dental schools was developing, albeit not keeping pace with clinical evidence and the development of increasingly predictable techniques and materials. Concurrently, surveys of dental practice indicate that dental amalgam still predominates as the 'material of choice' for the restoration of posterior teeth within UK general dental practice. In light of such considerations, the aim of this study was to investigate current teaching of posterior composites in Irish and UK dental schools. An online questionnaire which sought information in relation to the current teaching of posterior composites was developed and distributed to the 17 established Irish and UK dental schools with undergraduate teaching programmes in late 2009. Completed responses were received from all 17 schools (response rate = 100%). All 17 schools taught the placement of occlusal and two-surface occlusoproximal composites in premolar and permanent molar teeth. Two schools did not teach placement of three-surface occlusoproximal composites in either premolars or molars. In their preclinical courses, ten schools taught posterior composites before teaching dental amalgams. Fifty-five percent of posterior restorations placed by dental students were of composite (range = 10-90%) and 44% amalgam (range = 10-90%), indicating an increase of 180% in the numbers of posterior composites placed over the past five years. Diversity was noted in the teaching of clinical techniques and students at different schools are trained with different composites and bonding systems. Some cause for concern was noted in the teaching of certain techniques that were not in keeping with existing best evidence, such as the teaching of transparent matrix bands and light

  6. Complicated Crown-Root Fracture Treated Using Reattachment Procedure: A Single Visit Technique

    Full Text Available Complicated crown-root fracture of maxillary central and lateral incisors is common in case of severe trauma or sports-related injury. It happens because of their anterior positioning in oral cavity and protrusive eruptive pattern. On their first dental visit, these patients are in pain and need emergency care. Because of impaired function, esthetics, and phonetics, such patients are quite apprehensive during their emergency visit. Successful pain management with immediate restoration of function, esthetics and phonetics should be the prime objective while handling such cases. This paper describes immediate treatment of oblique crown root fracture of maxillary right lateral incisor with reattachment procedure using light transmitting fiber post. After two and half years, the reattached fragment still has satisfying esthetics and excellent function.

    Thirty-three patients with pain and decreased range of motion after traumatic derangement of the distal radioulnar and ulna-carpal joint were treated with a modified Darrach distal ulnar resection. Their ages ranged from 22 to 75 years (average, 50 years). Twenty-seven patients had Colles' or other distal radius fractures. Seven patients had ulnar resection for treatment of distal ulnar-carpal derangement. Follow-up averaged 54.4 months. The patients showed an average increase in extension of 58% and flexion increased by 40% (p less than 0.01). Pronation increased by 40% and supination increased by 60% (p less than 0.01). Average grip strength increased by 38% (p less than 0.05). Ninety-one percent good or excellent results were achieved with this procedure. The Darrach resection can predictably provide pain relief while improving strength and motion when attention is paid to minimal bony resection and meticulous soft tissue reconstruction.

    The CMS offline computing system is composed of roughly 80 sites (including most experienced T3s) and a number of central services to distribute, process and analyze data worldwide. A high level of stability and reliability is required from the underlying infrastructure and services, partially covered by local or automated monitoring and alarming systems such as Lemon and SLS; the former collects metrics from sensors installed on computing nodes and triggers alarms when values are out of range, the latter measures the quality of service and warns managers when service is affected. CMS has established computing shift procedures with personnel operating worldwide from remote Computing Centers, under the supervision of the Computing Run Coordinator on duty at CERN. This dedicated 24/7 computing shift personnel is contributing to detect and react timely on any unexpected error and hence ensure that CMS workflows are carried out efficiently and in a sustained manner.

    Full Text Available Aim. To describe a new technique of uterine manipulation in laparoscopic management of pelvic cancers. Material and Methods. We used a novel uterine hitch technique in 23 patients from May 2008 to October 2008. These patients underwent pelvic oncologic surgery including laparoscopic radical hysterectomy (n=7, laparoscopic anterior resection (n=4, laparoscopic abdominoperineal resection (n=3, laparoscopic posterior exenteration (n=4, or laparoscopic anterior exenteration (n=5. The uterus was hitched to the anterior abdominal.wall by either a single suture in the fundus or by sutures through the round ligaments. Results. The uterine hitch technique was successfully accomplished in all procedures. It was performed in less than 5 minutes in all cases. It obviated the need for vaginal manipulation. An extra port for retraction could be avoided. There were no intraoperative complications. Conclusion. A practical, cheap and reproducible method for uterine manipulation, during pelvic oncologic surgery is described. It improves the stability of the uterus and also obviates the need for keeping an additional assistant for vaginal manipulation in any of the procedures.

  11. Coracoid bone graft osteolysis after Latarjet procedure: A comparison study between two screws standard technique vs mini-plate fixation

    2013-01-01

    Full Text Available Aims: One of the reason for Latarjet procedure failure may be coracoid graft osteolysis. In this study, we aimed to understand if a better compression between the coracoid process and the glenoid, using a mini-plate fixation during the Latarjet procedure, could reduce the amount of coracoid graft osteolysis. Materials and Methods: A computed tomography scan analysis of 26 prospectively followed-up patients was conducted after modified Latarjet procedure using mini-plate fixation technique to determine both the location and the amount of coracoid graft osteolysis in them. We then compared our current results with results from that of our previous study without using mini-plate fixation to determine if there is any statistical significant difference in terms of corcacoid bone graft osteolysis between the two surgical techniques. Results: The most relevant osteolysis was represented by the superficial part of the proximal coracoid, whereas the deep part of the proximal coracoid graft is least involved in osteolysis and has best bone healing. The current study showed a significant difference only for the deep part of the distal coracoid with our previous study (P < 0.01. Discussion: To our knowledge, there are no studies in literature that show the causes of coracoid bone graft osteolysis after Latarjet procedure. Conclusion: Our study suggests that there is a significant difference only for the deep part of the distal coracoid in terms of osteolysis. At clinical examination, this difference did not correspond with any clinical findings. Level of Evidence: Level 4. Clinical Relevance: Prospective case series, Treatment study.

    Ultrasound (US) has proven to be an useful adjunct during the performance of peripheral nerve blocks. This study is the first dealing with the application of US guidance for the psoas-compartment-block which is used to achieve lumbar plexus blockades. A pilot study was carried out to establish the US anatomy of the lumbar paravertebral region and its blood vessels. Moreover, suitable transducers and US frequencies were assessed. The feasibility of US imaging of the psoas-compartment was studied on healthy volunteers (N=21) of varying body types (normal weight: N= 13; overweight: N=5; obese: N=3) in a first volunteer study. Additionally, the skin-plexus distances were measured. A second volunteer study (N=21) was carried out to investigate the US anatomy of the paravertebral blood vessels by means of power Doppler sonography. The technique of an US guided approach to the psoas-compartment was tested on embalmed cadavers (N=10) at the levels L2/L3, L3/L4 and L4/L5. Accuracy and safety of this technique were ver...

    Poirier, M

    2009-01-01

    The behavior of non-local thermal-equilibrium (NLTE) plasmas plays a central role in many fields of modern-day physics, such as laser-produced plasmas, astrophysics, inertial or magnetic confinement fusion devices, or X-ray sources. The proper description of these media in stationary cases requires to solve linear systems of thousands or more rate equations. A possible simplification for this arduous numerical task may lie in some type of statistical average, such as configuration or superconfiguration average. However to assess the validity of this procedure and to handle cases where isolated lines play an important role, it may be important to deal with detailed levels systems. This involves matrices with sometimes billions of elements, which are rather sparse but still involve thousands of diagonals. We propose here a numerical algorithm based on the LU decomposition for such linear systems. This method turns out to be orders of magnitude faster than the traditional Gauss elimination. And at variance with ...

    Lung transplantation in rats is technically difficult and results may vary. The non-suture cuff technique (non-suture [NS]), which involves using a cuff for anastomoses of vessels and airways, is commonly utilized to perform transplant procedures. However, the standard bronchial cuff may occlude the lumen, resulting in diminished graft survival. In contrast, the non-suture cuff technique for vascular anastomoses with bronchial suturing (bronchial suture [BS]), although more technically difficult, is known to have prolonged bronchial patency. We developed a "modified" NS technique that uses a larger and longer cuff for anastomoses and compared the efficacy of this procedure to the BS technique for lung transplantation. The BS procedure was performed in 146 transplant procedures. The modified NS procedure, which uses a larger cuff than the standard NS procedure, was performed in 113 procedures. Although total ischemic times were comparable, the total operation time in the NS group was significantly shorter than in the BS group (p technique is widely acknowledged to provide prolonged patency of bronchial anastomosis, graft survival in the NS group was observed up 17 months post-transplant. These data show that the NS technique, which is less technically difficult, results in shorter operative times compared with the BS procedure, and results in durable anastomoses of lung grafts.

    Arthroscopic treatment of bony Bankart lesions can be challenging. We present a new easy and reproducible technique for arthroscopic reduction and suture anchor fixation of bony Bankart fragments. A suture anchor is placed medially to the fracture on the glenoid neck, and its sutures are passed around the bony fragment through the soft tissue including the inferior glenohumeral ligament complex. The sutures of this anchor are loaded in a second anchor that is placed on the glenoid face. This creates a nontilting 2-point fixation that compresses the fragment into its bed. By use of the standard technique, additional suture anchors are used superiorly and inferiorly to the bony Bankart piece to repair the labrum and shift the joint capsule. We call this the "bony Bankart bridge" procedure.

    The most essential development in endovascular stroke treatment (EST) was the shift from intra-arterial thrombolysis to endovascular thrombectomy with dedicated thrombectomy devices, most notably the introduction of stent-retrievers. We evaluated procedural and clinical effectiveness and safety of different EST techniques over time. We retrospectively analyzed EST cases that were treated by the same interventionalist before (n=36) and after (n=50) stent-retrievers were established as the treatment device of first choice. EST techniques in the first cohort comprised intra-arterial thrombolysis (n=24), manual thrombus aspiration (n=15), the use of the Penumbra thrombectomy system (n=13) and the Phenox clot retriever (n=3), intracranial stenting (n=10), and EST with stent-retrievers as a salvage procedure (n=11). In the second cohort, EST with stent-retrievers was the treatment option of first choice (n=47). Intra-arterial thrombolysis (n=15) and stenting of the occluded vessel (n=1) were performed, whenever EST with stent-retrievers failed. In both cohorts, revascularization rates (TICI ≥2b) were high (91.7% and 86.0%, respectively). A significantly lower number of interventional techniques per case were required in the second cohort (mean ± SD, 1.4±0.5 vs. 2.1±0.9, P<0.001). Recanalization was achieved almost twice as fast in the second cohort (85 vs. 163 minutes on average, P<0.001). The rate of patients achieving good functional outcome (mRS ≤2) was higher in the second cohort (40.0% vs. 22.2%, P=0.083). Our findings imply that when stent-retrievers were established as first-line the treatment device a significantly lower number of interventional techniques per case were required and recanalization was achieved almost twice as fast.

    We aimed to evaluate existing research into the effectiveness and safety of two tongue base suspension (TBS) techniques (Repose(®) system and modified TBS) with or without uvulopalatopharyngoplasty (UPPP) in obstructive sleep apnea. The literature review was performed using PubMed database. Searched terms used included the keywords "sleep apnea", "surgery", "tongue", "tongue base", "suspension", "Repose", "uvulopalatopharyngoplasty", and "hypopharynx". Levels of evidences and grades of recommendations were determined according to the hierarchy proposed by Oxford Centre for Evidence-based Medicine. Seven studies including 113 patients met the eligibility criteria for TBS as a stand-alone procedure. Four of seven studies including 62 patients used the Repose(®), and three studies including 51 patients used the modified TBS. The success rates were higher in the studies that used modified technique (74.5 %) than those that used the Repose(®) (25.8 %), (p data of 413 patients were compared, the modified TBS was found to be associated with significantly higher success rates (73.7 vs. 56.7 %, p techniques with or without UPPP; although there is a trend toward improved outcome with modified technique.

    2017-05-01

    In 2012 the FDA approved a magnetic sphincter augmentation (MSA) device (LINX, Torax Medical, Inc) for placement around the lower esophageal sphincter as an alternative approach to fundoplication for gastroesophageal reflux disease (GERD). This is a relatively new procedure and there is not widespread familiarization with the standard indications and techniques of device placement. We present two operative videos to highlight the standard surgical technique and technical points needed for successful LINX placement. First will be placement in a standard indications setting of uncomplicated GERD with no hiatal hernia. Second will be placement with complicated anatomy due to alterations from prior gastric surgery and a hiatal hernia. Our experience has revealed that the LINX device can be placed safely in patients with normal or significantly altered anatomy but requires adherence to several key principles and technical points. This procedure offers a new option that is anatomically and physiologically unique compared to standard fundoplication, and that offers highly effective control of GERD with a less invasive approach.

  7. Shaeer’s Technique: A Minimally Invasive Procedure for Monsplasty and Revealing the Concealed Penis

    Science.gov (United States)

    2016-01-01

    Background: A concealed penis is a condition where part of the penis is invisible below the surface of the prepubic skin. Dermolipectomy can correct this condition, although it involves a long abdominal crease incision, or infrapubic incision around the base of the penis, and a possibility for genital lymphedema. This study describes Shaeer’s technique, a minimally invasive method for revealing the concealed penis. Methods: A 1- to 2-cm-long incision was cut over the anterior superior iliac spine (ASIS) on either side. A long curved blunt forceps was inserted from one incision, down to the base of the penis and then up to the contralateral ASIS. A 5-mm wide nonabsorbable tape was picked up by the forceps from 1 incision and pulled through to emerge from the other. Pulling on the tape cephalad pulled the mons pubis and revealed the penis. The tape was sutured to the periosteum overlying the ASIS on either side. Patients were followed up for 18 months for penile length, complications, and overall satisfaction. Results: Twenty patients were operated upon. Preoperatively, flaccid visible length was 3 ± 0.9 cm, and erect visible length was 8 ± 4.6 cm. Postoperatively, the flaccid visible length was 7.1 ± 2.1 cm, with a 57.9% improvement in length (P penis. PMID:27622092

  9. State-of-the-art techniques in operative dentistry: contemporary teaching of posterior composites in UK and Irish dental schools.

    LENUS (Irish Health Repository)

    Lynch, C D

    2010-08-14

    Advances of composite systems and their application have revolutionised the management of posterior teeth affected by caries, facilitating a minimally invasive approach. Previous surveys have indicated that the teaching of posterior composites within dental schools was developing, albeit not keeping pace with clinical evidence and the development of increasingly predictable techniques and materials. Concurrently, surveys of dental practice indicate that dental amalgam still predominates as the \\'material of choice\\' for the restoration of posterior teeth within UK general dental practice. In light of such considerations, the aim of this study was to investigate current teaching of posterior composites in Irish and UK dental schools.

  10. The Relationship between Interchangeability Standards and Precision Design in Teaching a Course on Interchangeability and Measurement Techniques

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This article discusses some views on the relationship between carrying out and applying standards and precision design and the teaching of a course on interchangeability and measurement techniques. It points out that while emphasizing precision design, we should not underrate the significance of interchangeability and standardization. Although there are presently many teaching models available for such courses, each course should be designed separately to preserve its systematic character and integrality. As well, the development of students' abilities in precision design and the application of standards should be strengthened in experimental lessons within each course.

    Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution. CTO operators with extensive IVUS experience in non-CTO cases carried out all procedures. Procedural and outcome data was prospectively entered into the institutional database and a retrospective analysis of clinical, angiographic and technical data performed. 17 (77%) of the 22 procedures were successful. The mean age was 59.8 ± 11.5 years, and 90.9% were male. The most commonly attempted lesions were located in the left anterior descending 36.4% (Soon et al. in J Intervent Cardiol 20(5):359-366, 2007) and Circumflex artery (LCx) 31.8% (Mollet et al. in Am J Cardiol 95(2):240-243, 2005). Mean JCTO score was 3.09 ± 0.75 (3.06 ± 0.68, 3.17 ± 0.98 in the successful and failed groups respectively p = 0.35). The mean contrast volume was 378.7 ml ± 114.7 (389.9 ml ± 130.5, 349.2 ml ± 52.2 p = 0.3 in the successful and failed groups respectively). There was no death, coronary artery bypass grafting or myocardial infarction requiring intervention in this series. When the success rates were analyzed taking into account the date of adoption of this technique, the learning curve had no significant impact on CTO-PCI success. This series describes a good success rate in IVUS guided stumpless wiring of CTOs in consecutive patients with this complex anatomical scenario.

    There are currently no practising psychiatrists in Somaliland. In 2007 the first medical students graduated from universities in Somaliland without mental health training. We aimed to pilot an intensive but flexible package of mental health training to all senior medical students and interns using interactive training techniques and to evaluate its effectiveness by assessing knowledge, skills and attitudes. Teaching techniques included didactic lectures, case based discussion groups and role playing. Informal feedback informed a flexible teaching package. Assessment tools designed specifically for this course included a pre and post course MCQ exam and an OSCE. Changes in students' attitudes were evaluated using a questionnaire administered before and after the course. In addition, a questionnaire administered following the course evaluated the changes students perceived in their knowledge and attitudes to mental health. The MCQ improved from 50.7% pre course to 64.4% post course (p = 9.73 E-08). Students achieved an average overall OSCE mark of 71%. The pre and post attitudes questionnaire was most significantly different for statements relevant to aetiology, stigma and the overlap between mental and physical health. The statement most strongly agreed with after the course was 'I now understand more about the overlap between mental and physical health'. Interactive teaching provided a learning experience for both students and trainers. On site and distance learning based on the teaching described here has widened the scope of the training possible in psychiatry and allowed the provision of regular teaching, supervision and peer support in Somaliland. However, the current lack of local expertise means that important issues of sustainability need to be considered in future work.

    Full Text Available First year accounting has generally been perceived as one of the more challenging first year business courses for university students. Various Classroom Assessment Techniques (CATs have been proposed to attempt to enrich and enhance student learning, with these studies generally positioning students as learners alone. This paper uses an educational case study approach and examines the implementation of the IGCRA (individual, group, classroom reflective action technique, a Classroom Assessment Technique, on first year accounting students’ learning performance. Building on theoretical frameworks in the areas of cognitive learning, social development, and dialogical learning, the technique uses reports to promote reflection on both learning and teaching. IGCRA was found to promote feedback on the effectiveness of student, as well as teacher satisfaction. Moreover, the results indicated formative feedback can assist to improve the learning and learning environment for a large group of first year accounting students. Clear guidelines for its implementation are provided in the paper.

    To avoid the disadvantages of chronic pain and chest wall paresthesia associated with video-assisted thoracic surgery (VATS) procedures, we developed a novel surgical technique for performing sympathectomy by embryonic natural orifice transumbilical endoscopic surgery (E-NOTES) with a flexible endoscope. In this study, we compared the outcomes of E-NOTES with conventional VATS thoracic sympathectomy on palmar hyperhidrosis. From January 2010 to April 2011, a total of 66 patients with severe palmar hyperhidrosis were treated with thoracic sympathectomy in our department. Thirty-four transumbilical thoracic sympathectomies were performed via a 5-mm umbilicus incision with ultrathin gastroscope, then compared with 32 conventional needlescopic thoracic sympathectomies. Retrospective statistical analysis of a prospectively collected group of patients was performed. There was no significant difference with regard to gender, mean age, body mass index, and length of hospital stay between the two groups. The operative time for E-NOTES thoracic sympathectomy was longer than that of VATS thoracic sympathectomy (56.4 ± 10.8 vs. 40.3 ± 6.5 min, p sympathectomy reported successful treatment of their palmar hyperhidrosis. Compensatory hyperhidrosis was noticed in 7 (20.1 %) and 6 (18.8 %) patients in the E-NOTES and VATS groups, respectively (p > 0.05). Postoperative pain and paresthesia were significantly reduced in the E-NOTES group at each time interval, and the aesthetic effect of the incision was superior in the E-NOTES group. Transumbilical-diaphragmatic thoracic sympathectomy is a safe and efficacious alternative to the conventional approach. This novel procedure can further reduce postoperative pain and chest wall paresthesia as well as afford maximum cosmetic benefits by hiding the surgical incision in the umbilicus.

  8. Teaching laboratory rodent research techniques under the tenets of situated learning improves student confidence and promotes collaboration.

    2014-07-01

    A targeted needs assessment at our institution revealed that the online system used to train researchers on performing techniques with animals did not provide opportunities to practice skills, introduce learners to animal care staff, nor satisfactorily support researchers' needs to become comfortable with laboratory animal species. To correct these deficiencies, a series of hands-on training sessions, framed theoretically in situated learning, was developed. This theoretical framework asserts that learning for everyday living (in this case, performing laboratory animal techniques) happens when people interact within the community while using the 'tools at hand' (that is, the instruments and jargon of the field). From this perspective, the students work alongside the instructor as apprentices. The instructor creates increasingly challenging learning opportunities as students work toward independently performing techniques. To test our hypothesis that teaching from this perspective improves comfort levels with laboratory animals and promotes collaborative relationships between animal care and research personnel, a mixed-method design involving online surveys (first survey, n = 45; second survey, n = 35) and semistructured interviews (n = 10) was used. Quantitative results revealed that students became more comfortable with laboratory animals and were more likely to contact animal care personnel due to participating in the training program. The qualitative arm of the study identified specific features of the training program that improved comfort levels for students (seeing then doing, working in small groups, learning within a comfortable environment, and building collegial relationships). These results support teaching rodent research techniques from the practical and theoretical approach of situated learning.

  9. Teaching and Assessment of High-Velocity, Low-Amplitude Techniques for the Spine in Predoctoral Medical Education.

    2016-09-01

    Although national didactic criteria have been set for predoctoral education and assessment in osteopathic manipulative treatment, there is no criterion standard for teaching methods and assessments of osteopathic manipulative treatment competence in colleges of osteopathic medicine. This issue is more pressing with the creation of the single graduate medical education accreditation system by the American Osteopathic Association and Accreditation Council for Graduate Medical Education, which introduced the creation of "osteopathic recognition" for residencies that want to incorporate osteopathic principles and practice into their programs. Residencies with osteopathic recognition may include both osteopathic and allopathic graduates. Increased standardization at the predoctoral level, however, is recommended as osteopathic principles and practice training applications are expanded. The objectives of this article are to review the standards for teaching osteopathic medical students high-velocity, low-amplitude (HVLA) techniques for the spine; to review and discuss the methods used to assess medical students' proficiency in using HVLA; and to propose baseline standards for teaching and assessing HVLA techniques among medical students.

    To review the initial experience of blending a variety of online educational techniques with traditional face to face or contact-based teaching methods to deliver final year undergraduate radiology content at a UK Medical School. The Brighton and Sussex Medical School opened in 2003 and offers a 5-year undergraduate programme, with the final 5 spent in several regional centres. Year 5 involves several core clinical specialities with onsite radiology teaching provided at regional centres in the form of small-group tutorials, imaging seminars and also a one-day course. An online educational module was introduced in 2007 to facilitate equitable delivery of the year 5 curriculum between the regional centres and to support students on placement. This module had a strong radiological emphasis, with a combination of imaging integrated into clinical cases to reflect everyday practice and also dedicated radiology cases. For the second cohort of year 5 students in 2008 two additional online media-rich initiatives were introduced, to complement the online module, comprising imaging tutorials and an online case discussion room. In the first year for the 2007/2008 cohort, 490 cases were written, edited and delivered via the Medical School managed learning environment as part of the online module. 253 cases contained a form of image media, of which 195 cases had a radiological component with a total of 325 radiology images. Important aspects of radiology practice (e.g. consent, patient safety, contrast toxicity, ionising radiation) were also covered. There were 274,000 student hits on cases the first year, with students completing a mean of 169 cases each. High levels of student satisfaction were recorded in relation to the online module and also additional online radiology teaching initiatives. Online educational techniques can be effectively blended with other forms of teaching to allow successful undergraduate delivery of radiology. Efficient IT links and good image quality

    Grauwin, M Y; Saboye, J; Cartel, J L

    1996-08-01

    This paper deals with the results observed in 21 ancient leprosy patients suffering from lagophthalmos (13 of whom suffered from bilateral lagophthalmos) and treated by the Edgerton-Montandon surgical procedure which associates lateral canthopexy and tarsorraphy. Eighteen of the 21 treated patients were reviewed at one month after the procedure and, overall, results could be evaluated for 30 eyes. Improvement was noted in all of the 30 eyes and, globally, the residual palpebral fissure (during voluntary closing of the eyes by the patient) decreased from 6.7 mm before the procedure to 1.8 after the procedure. The following recommendations may be proposed. For young patients with intact corneal sensation, the Gillies procedure remains the procedure of choice to correct lagophthalmos. For older patients with corneal anesthesia, at high risk of blindness, the Edgerton-Montandon procedure should be recommended.

    Glittenberg, Carl; Binder, Susanne

    2004-07-01

    Purpose: To create a more effective method of demonstrating complex subject matter in ophthalmology with the use of high end, 3-D, computer aided animation and interactive multimedia technologies. Specifically, to explore the possibilities of demonstrating the complex nature of the neuroophthalmological basics of the human oculomotor system in a clear and non confusing way, and to demonstrate new forms of retinal surgery in a manner that makes the procedures easier to understand for other retinal surgeons. Methods and Materials: Using Reflektions 4.3, Monzoom Pro 4.5, Cinema 4D XL 5.03, Cinema 4D XL 8 Studio Bundle, Mediator 4.0, Mediator Pro 5.03, Fujitsu-Siemens Pentium III and IV, Gericom Webgine laptop, M.G.I. Video Wave 1.0 and 5, Micrografix Picture Publisher 6.0 and 8, Amorphium 1.0, and Blobs for Windows, we created 3-D animations showing the origin, insertion, course, main direction of pull, and auxiliary direction of pull of the six extra-ocular eye muscles. We created 3-D animations that (a) show the intra-cranial path of the relevant oculomotor cranial nerves and which muscles are supplied by them, (b) show which muscles are active in each of the ten lines of sight, (c) demonstrate the various malfunctions of oculomotor systems, as well as (d) show the surgical techniques and the challenges in radial optic neurotomies and subretinal surgeries. Most of the 3-D animations were integrated in interactive multimedia teaching programs. Their effectiveness was compared to conventional teaching methods in a comparative study performed at the University of Vienna. We also performed a survey to examine the response of students being taught with the interactive programs. We are currently in the process of placing most of the animations in an interactive web site in order to make them freely available to everyone who is interested. Results: Although learning how to use complex 3-D computer animation and multimedia authoring software can be very time consuming and

    We investigated the effects of a least to most prompting procedure on the performance of board game steps and game-related on-task behavior of young children with special needs and their typically developing peers. This study was conducted employing a concurrent multiple baseline design across participants. After teaching the board game steps using a systematic prompting strategy, the participants demonstrated increases in the performance of board game steps and game-related on-task behavior. In addition, the participants maintained high levels of performance and game-related on-task behavior during post-game training. The effects of teaching board games using prompting strategies, implications for practice, and areas for future study are presented.

    The authors describe the Tulane Model for teaching cultural competence to psychiatry residents in order to outline an innovative approach to curricula development in academic psychiatry. The authors focus on the didactic experience that takes place during the first and second postgraduate years and present seven core concepts that should inform the emerging clinician's thinking in the formulation of every clinical case. The authors discuss the correspondence between each core concept and the Outline for Cultural Formulation, introduced in Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV and updated in DSM-5. The authors illustrate how each of the core concepts is utilized as a guideline for teaching residents a process for eliciting culturally relevant information from their patients and their personal histories and how to apply that knowledge in the assessment and treatment of patients in clinical settings.

    2011-01-01

    Full Text Available Teaching grammar in a way that enables students to use grammatical structures correctly in their active use has always been one of the intricate tasks for most practitioners. This study compared the ef­fectiveness of three instructional methods: games, dialogues practiced through role-play, and unfocused tasks for teaching grammar. Forty eight pre-intermediate female students participated in this study. The structures chosen were Conditional Sentence Type 2 and Wish structures for expressing present desires. A posttest was administered to assess the subjects' productive knowledge of the grammatical patterns. The results showed that there were no significant differences in the performance of groups. In other words, all three methods were equally effective to boost students' grammatical knowledge of the two structures.

    Full Text Available The purpose of this study was to determine differences in Anatolia Teacher High School teachers’ knowledge about methods and techniques before and after an in-service training. 120 teachers from various districts participated in the study but 104 of them were evaluated. Participants were from six different disciplines. A one group pretest-post test design was employed. Data collected evaluated qualitatively. Eleven open-ended questions were administered to participant teachers to evaluate if their development were differentiated with regard to the disciplines and experience. The results indicated that, before training teachers generally use question-answer strategy, lecturing and laboratory activities and there were not any differences with regard to the discipline and experience. However, an important increase in teachers’ knowledge about constructivist approach and teaching techniques was determined after in-service training.

    Kalwitzki, M; Beyer, C; Meller, C

    2010-11-01

    Whilst preparing undergraduate students for a clinical course in paediatric dentistry, four consecutive classes (n = 107) were divided into two groups. Seven behaviour-modifying techniques were introduced: systematic desensitization, operant conditioning, modelling, Tell, Show, Do-principle, substitution, change of roles and the active involvement of the patient. The behaviour-modifying techniques that had been taught to group one (n = 57) through lecturing were taught to group two (n = 50) through video sequences and vice versa in the following semester. Immediately after the presentations, students were asked by means of a questionnaire about their perceptions of ease of using the different techniques and their intention for clinical application of each technique. After completion of the clinical course, they were asked about which behaviour-modifying techniques they had actually used when dealing with patients. Concerning the perception of ease of using the different techniques, there were considerable differences for six of the seven techniques (P techniques seemed more difficult to apply clinically after lecturing, others seemed more difficult after video-based teaching. Concerning the intention for clinical application and the actual clinical application, there were higher percentages for all techniques taught after video-based teaching. However, the differences were significant only for two techniques in each case (P teaching enhances the intention for application and the actual clinical application only for a limited number of behaviour-modifying techniques. © 2010 John Wiley & Sons A/S.

  10. The Maxillary Sinus Membrane Elevation Procedure: Augmentation of Bone around Dental Implants without Grafts—A Review of a Surgical Technique

    Directory of Open Access Journals (Sweden)

    Christopher Riben

    2012-01-01

    Full Text Available Background. Long-term edentulism may in many cases result in resorption of the alveolar process. The sinus lift procedure aims to create increased bone volume in the maxillary sinus in order to enable installation of dental implants in the region. The method is over 30 years old, and initially autogenous bone grafts were used and later also different bone substitutes. Since 1997, a limited number of studies have explored the possibility of a graftless procedure where the void under the sinus membrane is filled with a blood clot that enables bone formation. Aim. To describe the evolution of the sinus-lift technique and to review the literature related to the technique with a focus on long-term studies related to the graft-less technique. Methods. The electronic database PubMed was searched, and a systematic review was conducted regarding relevant articles. Results. A relatively few long-term studies using the described technique were found. However, the technique was described as reliable considering the outcome of the existing studies. Conclusion. All investigated studies show high implant survival rates for the graftless technique. The technique is considered to be cost-effective, less time-consuming, and related to lower morbidity since no bone harvesting is needed.

    Eleazer, Paul D.; Gilbert, Gregg H.; Funkhouser, Ellen; Reams, G.J.; Law, A.S.; Benjamin, Paul L.

    2015-01-01

    Background Little is known about which materials and techniques general dentists (GDs) use during root canal procedures. The objectives were to: (1) quantify GD’s use of specific endodontic armamentarium; (2) quantify inappropriate use; and (3) ascertain if inappropriate use is associated with dentists’ practice characteristics. Methods GDs in the National Dental Practice-Based Research Network reported in a questionnaire materials and techniques they use during root canal procedures. Results 1,490 (87%) of eligible GDs participated. Most (93%; n=1,383) used sodium hypochlorite to irrigate. The most commonly used sealers were zinc oxide-eugenol (43%) and resin (40%), followed by calcium hydroxide (26%). A majority (62%; n=920) used a compaction obturation technique; 36% (n=534) used a carrier-based method. Most (96%; n=1,423) used gutta percha as a filler; 5% used paste fillers. Few used irrigants (n=46), sealers (n=4), techniques (n=49) or fillers (n=10) that investigators classified as ‘inappropriate’. Conclusions GDs use a broad range of endodontic techniques and materials, often adapting to newer technologies as they become available. Few GDs use armamentarium that the investigators classified as inappropriate. Practical Implications GDs use many types of endodontic techniques and materials, but only a very small percentage is not appropriate. PMID:26562726

    We evaluated the effect of fat suppression techniques (fatsat) and magnetization transfer contrast (MTC) for MR venography (MRV) using the 2D TOF sequence in the lower extremities. In addition, the improvement of vessel conspicuity resulting from three different warming procedures was evaluated. Three combinations of fatsat and MTC were performed. Both the signal intensity ratio (SIR) and contrast-to-noise ratio (CNR) were measured at ROIs of vein, fat, and muscle in knee. The vessel conspicuity of MIP was evaluated by three radiologists. The experimental results indicated that MTC pulses did not affect fatsat. The combination techniques of fatsat and MTC improved SIR ({approx_equal}13%) and CNR ((applox =)5%) of the vein compared with techniques using fatsat only. The continuous warming procedure was better than temporary warming in terms of vessel conspicuity. We conclude that the combined techniques of fatsat and MTC with the continuous warming procedure were clearly useful for MRV using the 2D TOF sequence in the lower extremities. (author)

    The success rate of percutaneous coronary intervention (PCI) for chronic total coronary occlusion (CTO) lesions varies depending on the guidewire manipulation skills of the operator. The standardization of guidewire technique is very important. A new technique with a new tapered wire (Conquest, Confianza Pro) was tested to verify effectiveness for higher initial success rates and standardization of PCI for CTO. A prospective, multicenter registry was conducted at 6 investigational sites. In the CONQUEST trial, The CTO lesions were treated by using an intermediate guidewire to cross the lesion. If it did not cross, the guidewire was changed to the Conquest guidewire. If it did not cross, "seesaw-wiring" or the "parallel-wire technique" was performed. The primary endpoint was the initial procedural success rate. A total of 110 patients representing 116 CTO lesions were treated from July 2003 through March 2004. The procedural success rate was 86.2% on the first try, and 88.8% on the second try, respectively. The guidewire success rate on the second try was 90.5% during the hospital stay; no deaths, or acute myocardial infarctions were confirmed. Two patients deteriorated into tamponade, and surgical or percutaneous drainage was performed in each patient without any sequelae. A guidewire technique in PCI for CTOs that starts with the intermediate guidewire and moves to the Confianza Pro tapered guidewire, either alone or by performing a see-saw or parallel-wire technique, can achieve a high initial success rate with an acceptably low major complication rate.

    North American dental schools were surveyed to determine the types of clinical experiences and the extent of material use that predoctoral students encounter with restorative procedures that employ all-ceramic materials. The results were based on an overall response rate of 80% from the 64 surveyed schools. The majority (96%) of the 51 schools responding to the survey did offer an opportunity to become experienced with all-ceramic restorations. The selection of bases and liners for all-ceramic restorations included dentin adhesive agents, glass ionomer materials, and calcium hydroxide products, by a ratio of 5:4:1, respectively. The most commonly used impression material types were addition silicone and polyether. One or both of these materials were used by every school. Dicor glass ceramic and alumina core ceramic were the most commonly used materials by the responding schools for veneers, onlays, and crowns. Dicor glass ceramic and CAD/CAM ceramic were most commonly used for inlays. Crowns were made of more different all-ceramic material types than the other restoration classes. Fabrication of all-ceramic restorations was primarily by commercial laboratories and school technicians. Students have hands-on experience in the fabrication of all-ceramic restorations in 6% of the responding schools. Luting agents for all-ceramic restorations include dual-cured resin, in 96% of the responding schools, light-cured resin, 43%, and glass ionomer cement, 33%. Zinc phosphate, chemical-cured composite, and polycarboxylate were used by less than one fourth of the respondents. Only resin-based composite materials were used to lute ceramic veneers. Rubber dam was applied primarily during luting procedures involving all-ceramic inlays and onlays. Crowns and veneers were isolated by this method in less than 30% of the responding schools. Finishing procedures with all-ceramic restorations were accomplished with three or more instruments by 89% of the schools.

    Motivational interviewing (MI) has been promoted in recent years as an effective method for engaging patients in positive health behaviors and increasing adherence to treatment regimens. The purpose of this study was to evaluate a brief training of MI techniques provided within the dental school curriculum. Third-year dental students received three hours of instruction on MI theory and techniques and then were assigned to use the method with a patient and report on their attempt in a paper. To determine if the brief training and paper assignment were effective methods for training students and assessing their understanding of MI methods, the papers were analyzed to assess aspects of the students' self-reported use of MI-related methods. Effective use of MI techniques was demonstrated by students who appropriately matched their intervention to the patient's stage of readiness to change, accurately recognized patient resistance, and responded to resistance. The paper assignment appeared to be an effective method to assess the students' use and understanding of MI-related techniques.

  14. Figure analysis: A teaching technique to promote visual literacy and active Learning.

    2016-07-08

    Learning often improves when active learning techniques are used in place of traditional lectures. For many of these techniques, however, students are expected to apply concepts that they have already grasped. A challenge, therefore, is how to incorporate active learning into the classroom of courses with heavy content, such as molecular-based biology courses. An additional challenge is that visual literacy is often overlooked in undergraduate science education. To address both of these challenges, a technique called figure analysis was developed and implemented in three different levels of undergraduate biology courses. Here, students learn content while gaining practice in interpreting visual information by discussing figures with their peers. Student groups also make connections between new and previously learned concepts on their own while in class. The instructor summarizes the material for the class only after students grapple with it in small groups. Students reported a preference for learning by figure analysis over traditional lecture, and female students in particular reported increased confidence in their analytical abilities. There is not a technology requirement for this technique; therefore, it may be utilized both in classrooms and in nontraditional spaces. Additionally, the amount of preparation required is comparable to that of a traditional lecture. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):336-344, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

    Inquiry-based teaching approaches are increasingly being adopted in biology laboratories. Yet teaching assistants (TAs), often novice teachers, teach the majority of laboratory courses in US research universities. This study analyzed the perspectives of TAs and their students and used classroom observations to uncover challenges faced by TAs during their first year of inquiry-based teaching. Our study revealed three insights about barriers to effective inquiry teaching practices: 1) TAs lack sufficient facilitation skills; 2) TAs struggle to share control over learning with students as they reconcile long-standing teaching beliefs with newly learned approaches, consequently undermining their fledgling ability to use inquiry approaches; and 3) student evaluations reinforce teacher-centered behaviors as TAs receive positive feedback conflicting with inquiry approaches. We make recommendations, including changing instructional feedback to focus on learner-centered teaching practices. We urge TA mentors to engage TAs in discussions to uncover teaching beliefs underlying teaching choices and support TAs through targeted feedback and practice. PMID:27158302

    The first-aid training necessary for obtaining a drivers license in Austria has a regulated and predefined curriculum but has been targeted for the implementation of a new course structure with less theoretical input, repetitive training in cardiopulmonary resuscitation (CPR) and structured presentations using innovative media. The standard and a new course design were compared with a prospective, participant- and observer-blinded, cluster-randomized controlled study. Six months after the initial training, we evaluated the confidence of the 66 participants in their skills, CPR effectiveness parameters and correctness of their actions. The median self-confidence was significantly higher in the interventional group [IG, visual analogue scale (VAS:"0" not-confident at all,"100" highly confident):57] than in the control group (CG, VAS:41). The mean chest compression rate in the IG (98/min) was closer to the recommended 100 bpm than in the CG (110/min). The time to the first chest compression (IG:25s, CG:36s) and time to first defibrillator shock (IG:86s, CG:92s) were significantly shorter in the IG. Furthermore, the IG participants were safer in their handling of the defibrillator and started with countermeasures against developing shock more often. The management of an unconscious person and of heavy bleeding did not show a difference between the two groups even after shortening the lecture time. Motivation and self-confidence as well as skill retention after six months were shown to be dependent on the teaching methods and the time for practical training. Courses may be reorganized and content rescheduled, even within predefined curricula, to improve course outcomes. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    To describe a novel percutaneous image-guided technique using a large-bore biopsy system to retrieve foreign bodies (FBs) accidentally retained during non-vascular interventional procedures. Between May 2013 and October 2015, five patients underwent percutaneous retrieval of five iatrogenic FBs, including a biopsy needle tip in the femoral head following osteoblastoma biopsy and radiofrequency ablation (RFA); a co-axial needle shaft within a giant desmoid tumour following cryoablation; and three post-vertebroplasty cement tails within paraspinal muscles. All FBs were retrieved immediately following original procedures under local or general anaesthesia, using combined computed tomography (CT) and fluoroscopic guidance. The basic technique involved positioning a 6G trocar sleeve around the FB long axis and co-axially advancing an 8G biopsy needle to retrieve the FB within the biopsy core. Retrospective chart review facilitated analysis of procedures, FBs, technical success, and complications. Mean FB size was 23 mm (range 8-74 mm). Four FBs were located within 10 mm of non-vascular significant anatomic structures. The basic technique was successful in 3 cases; 2 cases required technical modifications including using a stiff guide-wire to facilitate retrieval in the case of the post-cryoablation FB; and using the central mandrin of the 6G trocar to push a cement tract back into an augmented vertebra when initial retrieval failed. Overall technical success (FB retrieval or removal to non-hazardous location) was 100 %, with no complications. Percutaneous image-guided retrieval of iatrogenic FBs using a large-bore biopsy system is a feasible, safe, effective, and versatile technique, with potential advantages over existing methods.

    Background The lack of countertraction in endoscopic submucosal dissection (ESD) results in increased technical demand and procedure time. Although the suture-pulley method for countertraction has been reported, its effectiveness compared with the traditional ESD technique remains unclear. Objective To objectively analyze efficacy of countertraction using the suture-pulley method for ESD. Design Prospective ex vivo animal study. Setting Animal laboratory. Interventions Twenty simulated gastric lesions were created in porcine stomachs by using a standard circular template 30 mm in diameter. In the control arm (n = 10), ESD was performed by using the standard technique. In the suture-pulley arm (N = 10), a circumferential incision was made, and an endoscopic suturing device was used to place the suture pulley. Main Outcome Measurements The primary outcome of this study was total procedure time. Results The median total procedure time with the suture-pulley method was significantly shorter than the traditional ESD technique (median, 25% to 75%, interquartile range [IQR]: 531 seconds [474.3–549.3 seconds] vs 845 seconds [656.3–1547.5 seconds], P < .001). The median time (IQR) for suture-pulley placement was 160.5 seconds (150.0–168.8 seconds). Although there was a significantly longer procedure time for proximal versus middle/lower stomach lesions with traditional ESD (median, 1601 seconds; IQR, 1547.5–1708.8 seconds vs median, 663 seconds; IQR, 627.5–681.8 seconds; P =.01), there was no significant difference in procedure time for lesions of various locations when using the suture-pulley method. Compared with traditional ESD, the suture-pulley method was less demanding in all categories evaluated by the NASA Task Load Index. Limitations Ex vivo study. Conclusions The suture-pulley method facilitates direct visualization of the submucosal layer during ESD and significantly reduces procedure time and technical difficulty. In addition, the benefit of the suture

    Professional mediators have long possessed a skill set that is uniquely suited to facilitation of difficult conversations between and among individuals in emotionally charged situations. This skill set has increasingly been recognized as invaluable to the work of clinical ethics consultants as they navigate conflicts involving families, surrogates, and providers. Given widespread acknowledgment that communication difficulties lie at the root of many clinical ethics conflicts, mediation offers techniques to enhance communication between conflicting parties. This special section of The Journal of Clinical Ethics focuses on core aspects of the mediation process designed for effective management of clinical conflict emanating from communication breakdowns, highly charged value conflicts, and instances of perceived disrespect.

    Due to substantial progress made in road safety in the last ten years, the European Union (EU) renewed the ambitious agreement of halving the number of persons killed on the roads within the next decade. In this paper we develop a method that aims at finding an optimal target for each nation, in terms of being as achievable as possible, and with the cumulative EU target being reached. Targets as an important component in road safety policy are given as reduction rate or as absolute number of road traffic deaths. Determination of these quantitative road safety targets (QRST) is done by a top-down approach, formalized in a multi-stage adjustment procedure. Different QRST are derived under consideration of recent research. The paper presents a method to break the national target further down to regional targets in case of the German Federal States. Generalized linear models are fitted to data in the period 1991-2010. Our model selection procedure chooses various models for the EU and solely log-linear models for the German Federal States. If the proposed targets for the EU Member States are attained, the sum of fatalities should not exceed the total value of 15,465 per year by 2020. Both, the mean level and the range of mortality rates within the EU could be lowered from 28-113 in 2010 to 17-41 per million inhabitants in 2020. This study provides an alternative to the determination of safety targets by political commitments only, taking the history of road fatalities trends and population into consideration.

    Endoscopy-assisted breast surgery (EABS), a technique that optimizes cosmetic outcome because it is performed through small wounds hidden in inconspicuous areas, could be an alternative surgical technique for benign breast tumors. In this study, we report the preliminary results of 323 EABS procedures performed at our institution for the management of benign breast tumors. The medical records of patients who underwent EABS for benign breast lesions during the periods August 2010 to December 2015 were collected from the Changhua Christian Hospital EABS database. Data on clinicopathologic characteristics, type of surgery, hospital stay, and complications were analyzed to determine the effectiveness of the procedure for benign breast tumors. The operating time with the number of procedure performed was analyzed for learning curve evaluation. Patient satisfaction with cosmetic outcome was evaluated with a self-report questionnaire. A total of 323 EABS procedures were performed in 286 patients with benign breast lesions, including 249 (90.5%) patients with unilateral lesions. The mean age was 36 years, the mean tumor size was 2.2 cm, and the mean distance from the nipple to the tumor was 5.2 cm. Most (93.8%, 303/323) of these tumors were excised through a transareolar wound, 2.4% (8/323) through an axillary wound, and 0.3% (1/323) through the infra-mammary fold. Histopathologic analysis revealed that 63.5% (202/318) of the tumors were fibroadenoma-related lesions. The mean operative time was 81.4 min (59~89 min), which was decreased with experience increased. The overall rate of complications was 6.5%, and all were minor and wound-related. Among the 110 patients who participated in the self-report cosmetic outcome evaluation, 85.4% reported being satisfied with the cosmetic result, and almost all were satisfied with breast symmetry. Of the patients interviewed, 92.7% reported that they would choose the same procedure if they had to undergo the operation again. Our

    To adapt nursing studies to the European Higher Education Area, new teaching methods have been included that assign maximum importance to student-centered learning and collaborative work. The Jigsaw Technique is based on collaborative learning and everyone in the group must play their part because each student's mark depends on the other students. Home group members are given the responsibility to become experts in a specific area of knowledge. Experts meet together to reach an agreement and improve skills. Finally, experts return to their home groups to share all their findings. The aim of this study was to evaluate nursing student satisfaction with the Jigsaw Technique used in the context of a compulsory course in research methods for nursing. A cross-sectional study was conducted using a self-administered anonymous questionnaire administered to students who completed the Research Methods course during the 2012-13 and 2013-14 academic years. The questionnaire was developed taking into account the learning objectives, competencies and skills that should be acquired by students, as described in the course syllabus. The responses were compared by age group (younger or older than 22years). A total of 89.6% of nursing students under 22years believed that this methodology helped them to develop teamwork, while this figure was 79.6% in older students. Nursing students also believed it helped them to work independently, with differences according to age, 79.7% and 58% respectively (p=0.010). Students disagreed with the statement "The Jigsaw Technique involves little workload", with percentages of 88.5% in the group under 22years and 80% in older students. Most believed that this method should not be employed in upcoming courses, although there were differences by age, with 44.3% of the younger group being against and 62% of the older group (p=0.037). The method was not highly valued by students, mainly by those older than 22years, who concluded that they did not learn

    The presence of bacterial spores of the Bacillus cereus group in soils and stream sediments appears to be a sensitive indicator of several types of concealed mineral deposits, including vein-type gold deposits. The B. cereus assay is rapid, inexpensive, and inherently reproducible. The test, currently under investigation for its potential in mineral exploration, is recommended for use on a research basis. Among the aerobic spore-forming bacilli, only B. cereus and closely related strains produce an opaque zone in egg-yolk emulsion agar. This characteristic, also known as the Nagler of lecitho-vitellin reaction, has long been used to rapidly indentify and estimate presumptive B. cereus. The test is here adapted to permit rapid estimation of B. cereus spores in soil and stream-sediment samples. Relative standard deviation was 10.3% on counts obtained from two 40-replicate pour-plate determinations. As many as 40 samples per day can be processed. Enough procedural detail is included to permit investigation of the test in conventional geochemical laboratories using standard microbiological safety precautions. ?? 1985.

    A major part of fracture mechanics is concerned with studying the initiation and propagation of fatigue cracks. This typically requires constant monitoring of crack growth during fatigue cycles and the knowledge of the precise location of the crack tip at any given time. One technique currently available for measuring fatigue crack length is the Potential Drop method. The method, however, may be inaccurate if the direction of crack growth deviates considerably from what was assumed initially or the curvature of the crack becomes significant. Another popular approach is to optically view the crack using a high magnification microscope, but this entails a person constantly monitoring it. The present proposed technique uses an automated scheme, in order to eliminate the need for a person to constantly monitor the experiment. Another technique under development elsewhere is to digitize an optical image of the test specimen surface and then apply a pattern recognition algorithm to locate the crack tip. A previous publication showed that the self nulling eddy current probe successfully tracked a simulated crack in an aluminum sample. This was the impetus to develop an online real time crack monitoring system. An automated system has been developed which includes a two axis scanner mounted on the tensile testing machine, the probe and its instrumentation and a personal computer (PC) to communicate and control all the parameters. The system software controls the testing parameters as well as monitoring the fatigue crack as it propagates. This paper will discuss the experimental setup in detail and demonstrate its capabilities. A three dimensional finite element model is utilized to model the magnetic field distribution due to the probe and how the probe voltage changes as it scans the crack. Experimental data of the probe for different samples under zero load, static load and high cycle fatigue load will be discussed. The final section summarizes the major accomplishments

    McAllister, Margaret; Searl, Kerry Reid; Davis, Susan

    2013-12-01

    Simulation learning in nursing has long made use of mannequins, standardized actors and role play to allow students opportunity to practice technical body-care skills and interventions. Even though numerous strategies have been developed to mimic or amplify clinical situations, a common problem that is difficult to overcome in even the most well-executed simulation experiences, is that students may realize the setting is artificial and fail to fully engage, remember or apply the learning. Another problem is that students may learn technical competence but remain uncertain about communicating with the person. Since communication capabilities are imperative in human service work, simulation learning that only achieves technical competence in students is not fully effective for the needs of nursing education. Furthermore, while simulation learning is a burgeoning space for innovative practices, it has been criticized for the absence of a basis in theory. It is within this context that an innovative simulation learning experience named "Mask-Ed (KRS simulation)", has been deconstructed and the active learning components examined. Establishing a theoretical basis for creative teaching and learning practices provides an understanding of how, why and when simulation learning has been effective and it may help to distinguish aspects of the experience that could be improved. Three conceptual theoretical fields help explain the power of this simulation technique: Vygotskian sociocultural learning theory, applied theatre and embodiment.

    In this work, we present a teaching methodology using active-learning techniques in the course "Devices and Instrumentation" of the Erasmus Mundus Master's Degree in "Color in Informatics and Media Technology" (CIMET). A part of the course "Devices and Instrumentation" of this Master's is dedicated to the study of image sensors and methods to evaluate their image quality. The teaching methodology that we present consists of incorporating practical activities during the traditional lectures. One of the innovative aspects of this teaching methodology is that students apply the concepts and methods studied in class to real devices. For this, students use their own digital cameras, webcams, or cellphone cameras in class. These activities provide students a better understanding of the theoretical subject given in class and encourage the active participation of students.

    Fine-needle aspiration biopsy is an established method for the evaluation of thyroid nodules, but it has not been standardized worldwide yet. Adequacy of the aspirations is affected by several factors. The aim of this study is to determine the main factors affecting the adequacy and to suggest a procedural technique expected to reduce repeated procedures. A total of 393 aspiration procedures performed using either 22-gauge or 27-gauge needles were included in the study. The samplings were classified as inadequate or adequate according to the cytopathological reports, and results were compared. The rate of adequate samplings was higher in the 27-gauge group and the difference was statistically significant. Neither the size of nodules nor the number of slides used for smearing affected the adequacy. There was not a statistically significant relation between the needle size and the nodule size or the number of slides in terms of adequacy. Needle size is an important factor that affects the adequacy of samplings. The nodule size and the number of slides do not affect the adequacy. However, bloody and thicker smears are difficult for pathologists to evaluate and result in inadequacy.

    2016-01-01

    Full Text Available Adult scoliosis is defined as a spinal deformity in a skeletally mature patient with a Cobb angle of more than 10 degrees in the coronal plain. Posterior-only approach with rod and screw corrective manipulation to add strength of contra bending manipulation has correction achievement similar to that obtained by conventional combined anterior release and posterior approach. It also avoids the complications related to the thoracic approach. We reported a case of 25-year-old male adult idiopathic scoliosis with double curve. It consists of main thoracic curve of 150 degrees and lumbar curve of 89 degrees. His curve underwent direct contra bending posterior approach using rod and screw corrective manipulation technique to achieve optimal correction. After surgery the main thoracic Cobb angle becomes 83 degrees and lumbar Cobb angle becomes 40 degrees, with 5 days length of stay and less than 800 mL blood loss during surgery. There is no complaint at two months after surgery; he has already come back to normal activity with good functional activity.

    The aim of the present controlled clinical trial was to compare 2 incision techniques, papilla base incision (PBI) and sulcular incision (IS), evaluating changes in papilla and recession height over a 12-month period. A total of 24 subjects requiring endodontic surgery on a single tooth were enrolled. PBI was used in 1 group and IS in the other group. The primary outcomes were changes in gingival recession of the tooth affected by periapical lesions and the mesial and distal teeth and the mesial and distal papilla height using the treated tooth as the reference. Outcome variables were assessed at baseline and 12 months after the surgical intervention. Statistical analysis was performed by a blinded operator through appropriate tests, with significance set at a P value equal to .05. In the PBI group, the papilla height at the 12-month follow-up in the mesial and distal aspect decreased 0.10 ± 0.32 mm and 0.10 ± 0.32 mm, respectively, and 0.23 ± 0.68 mm and 0.25 ± 0.40 mm, respectively, in the IS group without any significant differences. There were no differences found for recession change values between groups. The PBI and IS approaches in endodontic surgery showed similar results in terms of papilla height preservation and recession changes. Copyright © 2016 American Association of Endodontists.

    One of the principal objectives of sustainable and green processing development remains the dissemination and teaching of green chemistry in colleges, high schools, and academic laboratories. This paper describes simple glassware that illustrates the phenomenon of extraction in a conventional microwave oven as energy source and a process for green analytical chemistry. Simple glassware comprising a Dean-Stark apparatus (for extraction of aromatic plant material and recovery of essential oils and distilled water) and a Vigreux column (as an air-cooled condenser inside the microwave oven) was designed as an in-situ extraction vessel inside a microwave oven. The efficiency of this experiment was validated for extraction of essential oils from 30 g fresh orange peel, a by-product in the production of orange juice. Every laboratory throughout the world can use this equipment. The microwave power is 100 W and the irradiation time 15 min. The method is performed at atmospheric pressure without added solvent or water and furnishes essential oils similar to those obtained by conventional hydro or steam distillation. By use of GC-MS, 22 compounds in orange peel were separated and identified; the main compounds were limonene (72.1%), β-pinene (8.4%), and γ-terpinene (6.9%). This procedure is appropriate for the teaching laboratory, does not require any special microwave equipment, and enables the students to learn the skills of extraction, and chromatographic and spectroscopic analysis. They are also exposed to a dramatic visual example of rapid, sustainable, and green extraction of an essential oil, and are introduced to successful sustainable and green analytical chemistry.

    Hospitals as integrated parts of the wide-ranging health care systems have dominant focus on health care provision to meet, maintain and promote people's health needs of a community. This study aimed to assess the service quality of teaching hospitals of Yazd University of Medical Sciences using Fuzzy Analytical Hierarchy Process (FAHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). A literature review and a qualitative method were used to obtain experts' viewpoints about the quality dimensions of hospital services to design a questionnaire. Then, using a self-made questionnaire, perceptions of 300 patients about the quality of delivered services were gathered. Finally, FAHP was applied to weigh each quality dimension and TOPSIS method to rank hospital wards. Six dimensions including responsiveness, assurance, security, tangibles, health communication and Patient orientation were identified as affecting aspects of hospital services quality among which, security and tangibles got the highest and lowest importance respectively (0.25406, 0.06883). Findings also revealed that in hospital A, orthopedics and ophthalmology wards obtained the highest score in terms of quality while cardiology department got the lowest ranking (0.954, 0.323). In hospital B, the highest and the lowest ranking was belonged to cardiology and surgical wards (0.895, 0.00) while in hospital C, surgical units were rated higher than internal wards (0.959, 0.851). Findings emphasized that the security dimension got the lowest ranking among SERVQUAL facets in studied hospitals. This requires hospital executives to pay special attention to the issue of patients' security and plan effectively for its promotion.

    Full Text Available Introduction. Reconstruction of chronic type B dissection and thoracoabdominal aortic aneurysm (TAAA remaining after the emergency reconstruction of the ascending thoracic aorta and aortic arch for acute type A dissection represents one of the major surgical challenges. Complications of chronic type B dissection are aneurysmal formation and rupture of an aortic aneurysm with a high mortality rate. We presented a case of visceral hybrid reconstruction of TAAA secondary to chronic dissection type B after the Bentall procedure with the elephant trunk technique due to acute type A aortic dissection in a high-risk patient. Case report. A 62 year-old woman was admitted to our institution for reconstruction of Crawford type I TAAA secondary to chronic dissection. The patient had had an acute type A aortic dissection 3 years before and undergone reconstruction by the Bentall procedure with the elephant trunk technique with valve replacement. On admission the patient had coronary artery disease (myocardial infarction, two times in the past 3 years, congestive heart disease with ejection fraction of 25% and chronic obstructive pulmonary disease. On computed tomography (CT of the aorta TAAA was revealed with a maximum diameter of 93 mm in the descending thoracic aorta secondary to chronic dissection. All the visceral arteries originated from the true lumen with exception of the celiac artery (CA, and the end of chronic dissection was below the origin of the superior mesenteric artery (SMA. The patient was operated on using surgical visceral reconstruction of the SMA, CA and the right renal artery (RRA as the first procedure. Postoperative course was without complications. Endovascular TAAA reconstruction was performed as the second procedure one month later, when the elephant trunk was used as the proximal landing zone for the endograft, and distal landing zone was the level of origin of the RRA. Postoperatively, the patient had no neurological deficit and

    Interbody fusion techniques have been promoted as an adjunct to lumbar fusion procedures in an effort to enhance fusion rates and potentially improve clinical outcome. The medical evidence continues to suggest that interbody techniques are associated with higher fusion rates compared with posterolateral lumbar fusion (PLF) in patients with degenerative spondylolisthesis who demonstrate preoperative instability. There is no conclusive evidence demonstrating improved clinical or radiographic outcomes based on the different interbody fusion techniques. The addition of a PLF when posterior or anterior interbody lumbar fusion is performed remains an option, although due to increased cost and complications, it is not recommended. No substantial clinical benefit has been demonstrated when a PLF is included with an interbody fusion. For lumbar degenerative disc disease without instability, there is moderate evidence that the standalone anterior lumbar interbody fusion (ALIF) has better clinical outcomes than the ALIF plus instrumented, open PLF. With regard to type of interbody spacer used, frozen allograft is associated with lower pseudarthrosis rates compared with freeze-dried allograft; however, this was not associated with a difference in clinical outcome.

    Small renal masses (T1a) are commonly diagnosed incidentally and can be treated with nephron-sparing surgery, preserving renal function and obtaining the same oncological results as radical surgery. Bigger lesions (T1b) may be treated in particular situations with a conservative approach too. We present our surgical technique based on robotic assistance for nephron-sparing surgery. We retrospectively analysed our series of 32 consecutive patients (two with 2 tumours and one with 4 bilateral tumours), for a total of 37 robotic nephron-sparing surgery (RNSS) performed between June 2008 and July 2012 by a single surgeon (G.C.). The technique differs depending on tumour site and size. The mean tumour size was 3.6 cm; according to the R.E.N.A.L. Nephrometry Score 9 procedures were considered of low, 14 of moderate and 9 of hight complexity with no conversion in open surgery. Vascular clamping was performed in 22 cases with a mean warm ischemia time of 21.5 min and the mean total procedure time was 149.2 min. Mean estimated blood loss was 187.1 ml. Mean hospital stay was 4.4 days. Histopathological evaluation confirmed 19 cases of clear cell carcinoma (all the multiple tumours were of this nature), 3 chromophobe tumours, 1 collecting duct carcinoma, 5 oncocytomas, 1 leiomyoma, 1 cavernous haemangioma and 2 benign cysts. Associated surgical procedures were performed in 10 cases (4 cholecystectomies, 3 important lyses of peritoneal adhesions, 1 adnexectomy, 1 right hemicolectomy, 1 hepatic resection). The mean follow-up time was 28.1 months ± 12.3 (range 6-54). Intraoperative complications were 3 cases of important bleeding not requiring conversion to open or transfusions. Regarding post-operative complications, there were a bowel occlusion, 1 pleural effusion, 2 pararenal hematoma, 3 asymptomatic DVT (deep vein thrombosis) and 1 transient increase in creatinine level. There was no evidence of tumour recurrence in the follow-up. RNSS is a safe and feasible technique

  5. In search for instructional techniques to maximize the use of germane cognitive resources: A case of teaching complex tasks in physics

    Science.gov (United States)

    Sliva, Yekaterina

    The purpose of this study was to introduce an instructional technique for teaching complex tasks in physics, test its effectiveness and efficiency, and understand cognitive processes taking place in learners' minds while they are exposed to this technique. The study was based primarily on cognitive load theory (CLT). CLT determines the amount of total cognitive load imposed on a learner by a learning task as combined intrinsic (invested in comprehending task complexity) and extraneous (wasteful) cognitive load. Working memory resources associated with intrinsic cognitive load are defined as germane resources caused by element interactivity that lead to learning, in contrast to extraneous working memory resources that are devoted to dealing with extraneous cognitive load. However, the amount of learner's working memory resources actually devoted to a task depends on how well the learner is engaged in the learning environment. Since total cognitive load has to stay within limits of working memory capacity, both extraneous and intrinsic cognitive load need to be reduced. In order for effective learning to occur, the use of germane cognitive resources should be maximized. In this study, the use of germane resources was maximized for two experimental groups by providing a learning environment that combined problem-solving procedure with prompts to self-explain with and without completion problems. The study tested three hypotheses and answered two research questions. The first hypothesis predicting that experimental treatments would reduce total cognitive load was not supported. The second hypothesis predicting that experimental treatments would increase performance was supported for the self-explanation group only. The third hypothesis that tested efficiency measure as adopted from Paas and van Merrienboer (1993) was not supported. As for the research question of whether the quality of self-explanations would change with time for the two experimental conditions, it was

    The objective of this study was to compare the frequency of spontaneous preterm delivery before 35 weeks in 7 dichorionic twin pregnancies obtained after loop electrosurgical excision procedure (LEEP) for cervical intraepithelial neoplasia (CIN) 2,3 with respect to 21 twin pregnancies without previous cervical treatment. All the pregnancies were obtained after assisted reproduction techniques (ART). Same age at delivery was observed between two groups (p = 0.81) and none of our twin pregnancies after LEEP had a threatened preterm labor while four controls (19%) underwent a spontaneous preterm delivery (p = 0.35). These preliminary data seem to indicate that LEEP may not be responsible of spontaneous preterm delivery in twin pregnancies subsequent to ART.

    The health-related quality of life (QOL) is one of the most important outcome indicators for elderly people undergoing aortic valve interventions, and should be assessed across different interventions, including emerging percutaneous techniques. The study aim was to assess the change in QOL after different procedures for aortic valve replacement (AVR). QOL was assessed using the Short Form-36 questionnaire (SF-36) for 59 patients after conventional AVR; of these patients, 28 had AVR via a J-sternotomy, a transapical approach was used in 20 patients, and a transfemoral approach in 34. The early mortality during hospitalization was not significantly different among all four groups. The inverse probability weighted propensity scores adjusted Kaplan-Meier curve revealed that the transapical group had the lowest survival rate. The treatment effect analysis was most prominent in the transfemoral transcatheter aortic valve implantation (TAVI) group across all domains for QOL. The multivariate hierarchical linear mixed final fitted model shows that the transapical TAVI procedure and NYHA class (III-IV) had a significant negative effect on the physical domain and overall QOL score. Changes in QOL after interventions on the aortic valve were determined by the patient's preoperative status and the surgical intervention. The transcatheter intervention, even in 'sicker' patients, provided a gain in QOL comparable with that after an open-heart procedure. Transfemoral TAVI was shown to have advantages over transapical TAVI in terms of QOL improvement at three months and six months, and should be considered the first choice for patients in the high-risk surgical group.

    Full Text Available Abstract Background Simulation is increasingly used for teaching medical procedures. The goal of this study was to assess learner preferences for how simulators should be used in a procedural curriculum. Methods A 26-item survey was constructed to assess the optimal use of simulators for the teaching of medical procedures in an internal medicine residency curriculum. Survey domains were generated independently by two investigators and validated by an expert panel (n = 7. Final survey items were revised based on pilot survey and distributed to 128 internal medicine residents. Results Of the 128 residents surveyed, 106 (83% responded. Most responders felt that simulators should be used to learn technical skills (94%, refine technical skills (84%, and acquire procedural teaching skills (87%. Respondents felt that procedures most effectively taught by simulators include: central venous catheterization, thoracentesis, intubation, lumbar puncture, and paracentesis. The majority of learners felt that teaching should be done early in residency (97%. With regards to course format, 62% of respondents felt that no more than 3-4 learners per simulator and an instructor to learner ratio of 1:3-4 would be acceptable. The majority felt that the role of instructors should include demonstration of technique (92%, observe learner techniques (92%, teach evidence behind procedural steps (84% and provide feedback (89%. Commonly cited barriers to procedural teaching were limitations in time, number of instructors and simulators, and lack of realism of some simulators. Conclusions Our results suggest that residents value simulator-based procedural teaching in the form of small-group sessions. Simulators should be an integral part of medical procedural education.

    Full Text Available Traditionally and conventionally, gross anatomy is taught by lectures and cadaveric dissection and the lectures are taken with chalk and board (C&B or chalk and talk method in, India. But there is always a debate over the most effective method of lecture delivery. AIM : The aim of this study was to compare the role and effectiveness chalk and board method versus power point presentation ( S tudent’s perception as a lecture delivering method for teaching gross anatomy. METHODS: This was a questionnaire based study where 140 out of 150 first professional MBBS students of Medical College Jammu, were asked to fill anonymously a questionnaire about their perceptions of these two lecture delivery methods. The results were analyzed to see if there was any preference of students for any particular method. RESULTS: The majority of the medical students (90.7% preferred PPT presentations, while only 9.3% of students preferred the lectures using chalkboard method. CONCLUSION: Most of the students clearly preferred and accepted the use of PPT presentations, as compared to conventional board teaching for delivery method. So teaching gross anatomy should be carefully amalgamated with use of power point in lecture hall.

  14. Technical communication: new teaching model for practicing ultrasound-guided regional anesthesia techniques: no perishable food products!

    Liu, Yang; Glass, Nancy L; Power, Robert W

    2010-04-01

    There is a pronounced learning curve for the technique of ultrasound-guided regional anesthesia. Practicing with a simulator model has been shown to speed the acquisition of these skills for various ultrasound-guided procedures. However, commercial models for ultrasound-guided regional anesthesia may be too costly or not readily available. Models using turkey breasts or tofu blocks have the disadvantage of containing perishable food products that can be a source for infection. We describe an alternative inexpensive model that is made from nonperishable components readily available in the operating room. The materials required include 1 clean used 500-mL bag of IV fluids, a bottle of Premisorb (TYCO Healthcare Group, Mansfield, MA), and a piece of foam material approximately 0.3 cm in diameter and 5 cm in length trimmed from operating room foam pads. After filling the IV bag with tap water and inserting the foam into the IV bag from the outlet port of the IV bag, one-third of a bottle of Premisorb (approximately 15 g) is poured into the IV bag. The outlet port of the bag is then sealed by taping the rubber stopper that originally came with the bag. Premisorb, a solidifying agent frequently used to absorb irrigating fluids or blood in operating room suction canisters, produces a gel-like material in the IV bag. The foam inserted into the bag creates a relatively hyperechoic target. This gel-like substance in the bag will seal the holes created after multiple practice needle insertions, resulting in minimal leakage. The semitransparent nature of the gel allows the trainee to visualize the target directly and on the ultrasound screen. The model we describe is inexpensive and easy to make from materials readily available in the operating room with the advantages of being nonperishable, easy to carry, and reusable.

    Full Text Available Nazi Culture would seem at first to be a very esoteric subject to teach to the rather practical-minded and not very cosmopolitan students of a northern New Jersey state college. But of course it is really a distancing technique, a Verfremdungseffekt a la Brecht. Teaching fascism is not really teaching fascism per se, but an angle for teaching capitalism and socialism. And teaching Nazi culture is an angle for teaching some of the purposes of capitalist ideology.

    1997-11-01

    This paper provides a report of the usage of a phenomenological research methodology to investigate the influence on clinical practice of pre- and post-registration nurse education which makes explicit use of experiential teaching and learning approaches. The primary aim of the research was to explore the use of a phenomenological research methodology to examine the students' understanding of experiential teaching and learning. The claims made for the use of experiential teaching and learning approaches in both pre- and post-registration nurse courses and how clinical practice is influenced by the experiential learning elements of pre- and post-registration nurse education were also examined. The first stage of the enquiry involved focused non-directive interviews with members of BSc Nursing Studies and MSc Mental Health Branch programmes. Both programmes claim to make use of experiential teaching and learning. The data were analysed using a technique developed by Giorgi. Previous experiences of experiential teaching and learning were probed, student interpretations differentiated, and the relationship between course-based learning using experiential approaches and the implications for it's influence on practice were examined. The second stage of the enquiry has followed up the initial findings, exploring the students' experience of experiential approaches on their courses both in the classroom and in work-based learning situations. The findings are presented and discussed in the context of other studies from both nurse and higher education. Throughout the paper methodological concerns arising are discussed. The paper concludes with the identification of methodological problems arising from the research strategy: the implications of the power nexus created when teachers research students, and issues relating to the use of a phenomenological methodology in a longitudinal study.

    Purpose: It is well known that pacemaker implantation is sometimes needed in pregnant patients with symptomatic bradycardia. To our knowledge, there is no reported experience regarding radiation doses to the unborn child resulting from fluoroscopy during pacemaker implantation. The purpose of the current study was to develop a method for estimating embryo/fetus dose from fluoroscopically guided pacemaker implantation procedures performed on pregnant patients during all trimesters of gestation. Methods: The Monte Carlo N-Particle (MCNP) radiation transport code was employed in this study. Three mathematical anthropomorphic phantoms representing the average pregnant patient at the first, second and third trimesters of gestation were generated using Bodybuilder software (White Rock science, White Rock, NM). The normalized embryo/fetus dose from the posteroanterior (PA), the 30° left-anterior oblique (LAO) and the 30° right-anterior oblique (RAO) projections were calculated for a wide range of kVp (50–120 kVp) and total filtration values (2.5–9.0 mm Al). Results: The results consist of radiation doses normalized to a) entrance skin dose (ESD) and b) dose area product (DAP) so that the dose to the unborn child from any fluoroscopic technique and x-ray device used can be calculated. ESD normalized doses ranged from 0.008 (PA, first trimester) to 2.519 μGy/mGy (RAO, third trimester). DAP normalized doses ranged from 0.051 (PA, first trimester) to 12.852 μGy/Gycm2 (RAO, third trimester). Conclusion: Embryo/fetus doses from fluoroscopically guided pacemaker implantation procedures performed on pregnant patients during all stages of gestation can be estimated using the method developed in this study.

    This study reports an early, single-institution experience of combined thoracoscopic and laparoscopic robotic-assisted minimally invasive esophagectomy (RAMIE) using a four-arm robotic platform, with special attention given to the pitfalls and complications during procedure development. We conducted a prospective, single-cohort, observational study of patients undergoing RAMIE at a single institution. A total of 21 patients (median age, 62 years [range, 37-83 years]) underwent RAMIE with a four-arm robotic platform (17 by Ivor Lewis and 4 by McKeown). Of the patients, 17 (81%) had a complete (R0) resection, and 16 (76%) received induction treatment, the majority (14/21 [67%]) with combined chemoradiation. The median operative time was 556 min (range, 395-807 min), which decreased to 414 min (range, 405-543 min) for the last 5 cases in the series. The median estimated blood loss was 307 cm(3) (range, 200-500 cm(3)), and the median length of hospital stay was 10 days (range, 7-70 days). The median number of lymph nodes resected was 20 (range, 10-49). Five (24%) patients were converted to open procedures. Five patients (24%) had major complications. One (5%) died of complications on postoperative Day 70, and 3 (14%) had clinically significant anastomotic leaks (Grade II or greater, by Common Terminology Criteria for Adverse Events version 3.0). Three patients (14%) in this early experience developed airway fistulas. While four-arm RAMIE may offer advantages over standard minimally invasive esophagectomy approaches, its adoption in a structured program, with critical evaluation of adverse events and subsequent adjustment of technique, is paramount to maximize patient safety, minimize complications and improve the conduct of operation early in the learning curve. Particular technical consideration should be given to prevention of airway complications.

    The objective of this work was to develop a classification system in order to confirm the authenticity of Galician potatoes with a Certified Brand of Origin and Quality (CBOQ) and to differentiate them from other potatoes that did not have this quality brand. Elemental analysis (K, Na, Rb, Li, Zn, Fe, Mn, Cu, Mg and Ca) of potatoes was performed by atomic spectroscopy in 307 samples belonging to two categories, CBOQ and Non-CBOQ potatoes. The 307 x 10 data set was evaluated employing multivariate chemometric techniques, such as cluster analysis and principal component analysis in order to perform a preliminary study of the data structure. Different classification systems for the two categories on the basis of the chemical data were obtained applying several commonly supervised pattern recognition procedures [such as linear discriminant analysis, K-nearest neighbours (KNN), soft independent modelling of class analogy and multilayer feed-forward neural networks]. In spite of the fact that some of these classification methods produced satisfactory results, the particular data distribution in the 10-dimensional space led to the proposal of a new vector quantization-based classification procedure (VQBCP). The results achieved with this new approach (percentages of recognition and prediction abilities > 97%) were better than those attained by KNN and can be compared advantageously with those provided by LDA (linear discriminant analysis), SIMCA (soft independent modelling of class analogy) and MLF-ANN (multilayer feed-forward neural networks). The new VQBCP demonstrated good performance by carrying out adequate classifications in a data set in which the classes are subgrouped. The metal profiles of potatoes provided sufficient information to enable classification criteria to be developed for classifying samples on the basis of their origin and brand.

    The purpose of this study was to determine the efficacy of a modified vertebral column resection for the treatment of thoracolumbar angular kyphosis. A total of 13 patients (8 male, 5 female) with thoracolumbar kyphosis (kyphotic angle > 60°) were included in this study (Group A). There were 3 patients with failure of spinal formation (Type 1 deformity), 6 patients with old thoracic or lumbar compression fracture, and 4 patients with old spinal tuberculosis (including 1 case of T3-5 vertebral malunion). The average preoperative kyphotic angle was 67.3° (range 62°-75°). Each patient underwent an expanded eggshell procedure combined with the closing-opening technique for the treatment of thoracolumbar angular kyphosis. Sixteen patients who were previously treated with a closing-opening wedge osteotomy in the same spine classification group (kyphotic angle > 60°) were used as a control group (Group B). In Group A, the average (± SD) operative time was 400 ± 60 minutes, and the average blood loss was 960 ± 120 ml. There were no surgery-related complications observed during or after the operations. The average local kyphotic angle was 20.3° (range 18°-24.5°), and the average correction rate was 68.7%. In Group B, the average operative time was 470 ± 90 minutes, and the average blood loss was 2600 ± 1600 ml (range 1200-8200 ml). There were segmental vessels and spinal canal venous plexus injury in 1 case, spinal cord injury in 1 case, dural tearing in 2 cases, pleural rupture in 2 cases, and hemothorax and pneumothorax in 1 case. Each patient had more than 2 years of follow-up. At the latest follow-up examination, the average regional kyphotic angle was 19.9° ± 9.1° (range 19°-34°), and there was no significant loss of correction (p > 0.05). There was greater blood loss and a higher complication rate in Group B than in Group A (p < 0.05). An expanded eggshell procedure combined with the closing-opening technique for the treatment of thoracolumbar

    Full Text Available The objective of this study is to help students in developing their ideas in writing due to their difficulties to arrange ideas. Although they do have ideas, they cannot structure their ideas well in their papers. Several factors could cause this problem such as lack of vocabulary and knowledge or strategies in arranging ideas in papers. Another factor is unclear explanation and insufficient guidance from the teachers. Based on literature review, dictoglos can be a guide for students to develop their ideas in writing. It is a teaching technique which incorporates various activities such listening, taking notes, discussing, and reconstructing which have some standard procedures and variations.

  10. Rapid Analysis Procedures for Triglycerides and Fatty Acids as Pentyl and Phenethyl Esters for the Detection of Butter Adulteration Using Chromatographic Techniques

    Directory of Open Access Journals (Sweden)

    Daniele Naviglio

    2017-01-01

    Full Text Available This paper presents the development of three methods for quality control, fraud detection, and authentication of butter fat and other oils/fats using chromatographic techniques, with one method for triglycerides and two methods for fatty acids (FAs. The procedure for the analysis of triglycerides requires only dissolution of the sample in n-hexane and gas chromatography (GC analysis using a capillary column. The second method is based on the transesterification of triglycerides as pentyl esters in a single-step reaction using sodium pentanoate in pentanol. The reaction proceeds at room temperature and is similar to the potassium hydroxide-catalysed transesterification of triglycerides with methanol and even more similar to the sodium methoxide method and sodium butanoate method. The advantage of using pentyl esters includes reducing the volatility of short-chain FAs, and substantial recoveries were obtained compared with methyl ester analysis. The third method involves the transesterification of triglycerides in fat through reaction with 2-phenylethanol in a single step; 2-phenylethanol possesses a chromophore, and the phenethyl esters formed are analysed by high-performance liquid chromatography (HPLC with UV detection.

  18. Teaching Organic Chemistry via Student-Directed Learning: A Technique that Promotes Independence and Responsibility in the Student

    Science.gov (United States)

    Katz, Marlene

    1996-05-01

    One of the frustrations of teaching is the failure of talented students due to lack of effort on their part. We have to admit that Organic chemistry presents many challenges to students. At the same time we are aware that students often defeat themselves by a combination of procrastination and cramming. The Student-Directed Learning (SDL) method discourages this student strategy. Instead SDL fosters increased self-confidence, independence, and an awareness of the student's role in the teaching/learning process. This method incorporates four criteria for acceptance of responsibility: student ownership, student-active learning, student accountability, and student control. With SDL the course content is reorganized to make it more accessible to students. Learning modules are centered around "The Big Ideas". Each big idea is connected to its usefulness in pharmaceutical science, or is identified as a foundation idea for understanding subsequent course material. The class session is changed from traditional lecture to continuous dialogue between teacher and learners. Reading quizzes emphasize the importance of conscientious preparation for class. Structured retesting is offered to increase student self-confidence and learning. The extra effort required by the SDL method is more than compensated for by the improved grades, ACS exam scores, and student attitudes towards the course.
