    The gastric sleeve resection and gastric bypass are the 2 most commonly performed bariatric procedures. This article provides an overview of current teaching and learning methods of those techniques in resident and fellow training. A database search was performed on Pubmed, Embase, and the Education Resources Information Center (ERIC) to identify the methods used to provide training in bariatric surgery worldwide. After exclusion based on titles and abstracts, full texts of the selected articles were assessed. Included articles were reviewed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. In total, 2442 titles were identified and 14 full text articles met inclusion criteria. Four publications described an ex vivo training course, and 6 focused on at least 1 step of the gastric bypass procedure. Two randomized controlled trials (RCT) provided high-quality evidence on training aspects. Surgical coaching caused significant improvement of Bariatric Objective Structured Assessment of Technical Skills (BOSATS) scores (3.60 vs. 3.90, p = 0.017) and reduction of technical errors (18 vs. 10, p = 0.003). A preoperative warm-up increased global rating scales (GRS) scores on depth perception (p = 0.02), bimanual dexterity (p = 0.01), and efficiency of movements (p = 0.03). Stepwise education, surgical coaching, warming up, Internet-based knowledge modules, and ex vivo training courses are effective in relation to bariatric surgical training of residents and fellows, possibly shortening their learning curves.

    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.

    Skin and soft tissue infections are increasingly prevalent clinical problems, and it is important for health care practitioners to be well trained in how to treat skin abscesses. A realistic model of abscess incision and drainage will allow trainees to learn and practice this basic physician procedure. We developed a realistic model of skin abscess formation to demonstrate the technique of incision and drainage for educational purposes. The creation of this model is described in detail in this report. This model has been successfully used to develop and disseminate a multimedia video production for teaching this medical procedure. Clinical faculty and resident physicians find this model to be a realistic method for demonstrating abscess incision and drainage. This manuscript provides a detailed description of our model of abscess incision and drainage for medical education. Clinical educators can incorporate this model into skills labs or demonstrations for teaching this basic procedure.

    Graduating Internal Medicine residents must possess sufficient skills to perform a variety of medical procedures. Little is known about resident experiences of acquiring procedural skills proficiency, of practicing these techniques, or of being assessed on their proficiency. The purpose of this study was to qualitatively investigate resident 1) experiences of the acquisition of procedural skills and 2) perceptions of procedural skills assessment methods available to them. Focus groups were conducted in the weeks following an assessment of procedural skills incorporated into an objective structured clinical examination (OSCE). Using fundamental qualitative description, emergent themes were identified and analyzed. Residents perceived procedural skills assessment on the OSCE as a useful formative tool for direct observation and immediate feedback. This positive reaction was regularly expressed in conjunction with a frustration with available assessment systems. Participants reported that proficiency was acquired through resident directed learning with no formal mechanism to ensure acquisition or maintenance of skills. The acquisition and assessment of procedural skills in Internal Medicine programs should move toward a more structured system of teaching, deliberate practice and objective assessment. We propose that directed, self-guided learning might meet these needs.

    2017-03-01

    Full Text Available Smooth running of the educational process and the results depend a great deal on the methods used. The methodology of teaching offers a great variety of teaching techniques that the teacher can make use of in the teaching/learning process. Such techniques as brainstorming, the cube, KLW, case study, Venn diagram, and many other are familiar to the teachers and they use them effectively in the classroom. The present article proposes a technique called ‘survey’, which has been successfully used by the author as a student-centered speaking activity in foreign language classes. It has certain advantages especially if used in large groups. It can be adapted for any other discipline in the case when the teacher wishes to offer the students space for cooperative activity and creativity.

    The development of didactic means to create opportunities to permit complete and repetitive viewing of surgical procedures is of great importance nowadays due to the increasing difficulty of doing in vivo training. Thus, audiovisual resources favor the maximization of living resources used in education, and minimize problems arising only with verbalism. To evaluate the use of digital video as a pedagogical strategy in surgical technique teaching in medical education. Cross-sectional study with 48 students of the third year of medicine, when studying in the surgical technique discipline. They were divided into two groups with 12 in pairs, both subject to the conventional method of teaching, and one of them also exposed to alternative method (video) showing the technical details. All students did phlebotomy in the experimental laboratory, with evaluation and assistance of the teacher/monitor while running. Finally, they answered a self-administered questionnaire related to teaching method when performing the operation. Most of those who did not watch the video took longer time to execute the procedure, did more questions and needed more faculty assistance. The total exposed to video followed the chronology of implementation and approved the new method; 95.83% felt able to repeat the procedure by themselves, and 62.5% of those students that only had the conventional method reported having regular capacity of technique assimilation. In both groups mentioned having regular difficulty, but those who have not seen the video had more difficulty in performing the technique. The traditional method of teaching associated with the video favored the ability to understand and transmitted safety, particularly because it is activity that requires technical skill. The technique with video visualization motivated and arouse interest, facilitated the understanding and memorization of the steps for procedure implementation, benefiting the students performance.

    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.

  6. Teaching Health Care Students the Radial Arterial Puncture Procedure.

    Collins, Kevin P; Russian, Christopher J; Gonzales, Joshua F

    2016-01-01

    The radial artery puncture is a frequently ordered medical procedure for patients requiring blood gas analysis. Deviating from the proper procedure increases the likelihood of error and jeopardizes patient safety. The teaching methodology for the radial artery puncture is rarely addressed in the medical literature. First-year respiratory care students enrolled in a clinical practice course participated in an expanded curriculum on arterial puncture technique. The new five-step curriculum included: 1) a face-to-face lecture, 2) radial artery localization, 3) blunt-tipped needle simulation, 4) manikin arm puncture, and 5) a peer assessment video. Students participated in an inter-rater reliability exercise for step five. The multi-step process for teaching the arterial puncture stressed process over outcome. Students were required to master each step with a satisfactory evaluation to successfully pass the unit. Students also demonstrated high inter-rater evaluation scores of a peer video of the arterial puncture. Additional research is needed to determine if widespread application of the curriculum across other respiratory care programs and other healthcare disciplines is possible. The detailed report of our new curriculum offers other academic researchers the ability to formally study its usefulness.

    Performing a clinical procedure requires the integration of technical clinical skills with effective communication skills. However, these skills are often taught separately. To explore the feasibility and benefits of a new conceptual model for integrated skills teaching. : Design A qualitative observation and interview-based study of undergraduate medical students. Medical students performed technical and communication skills in realistic clinical scenarios (urinary catherization and wound closure), using latex models connected to simulated patients (SPs). Procedures were observed, videorecorded and assessed by tutors from an adjoining room. Students received immediate feedback from tutors and SPs, before engaging in a process of individual feedback through private review of their videotapes. Group interviews explored the response of students, SPs and tutors. Data were analysed using standard qualitative techniques. Fifty-one undergraduate students were recruited from the Faculty of Medicine, Imperial College, London. The scenarios provided a realistic simulation of two common clinical situations and proved feasible in terms of time, facilities and resources within this institution. Students found the opportunity to integrate communication and technical skills valuable, challenging and an appropriate learning experience. Immediate feedback was especially highly valued. Some students found difficulty integrating technical and communications skills, but benefited from conducting two procedures in the same session. The integrated model was feasible and was perceived to be valuable. Benefits include the opportunity to integrate, within a safe environment, skills which are often taught separately. Promoting reflective practice may enable the successful transfer of these integrated skills to other procedures.

    Full Text Available In teaching a general course on mathematics for prospective teachers, I have found the theoretical distinction between conceptual knowledge and procedural knowledge (Hiebert & Lefevre, 1986 a useful focus for teaching practice. The constructs provide a scaffold for the learning of mathematics by the students and for thinking about the teaching of mathematics in the school environment. These theoretical insights uncover in part the processes for acquiring knowledge and provide a tool for addressing problematic areas of learning.

    2018-01-01

    In order to facilitate the learning of distal radius shortening osteotomy by junior surgeons, the main assumption was that using a three-dimensional procedural simulator was better than a bone procedural simulator. After viewing a video, ten junior surgeons performed a distal radius shortening osteotomy: five with a bone procedural simulator (Group 1) and five with a three-dimensional procedural simulator (Group 2). All subsequently performed the same surgery on fresh cadaveric bones. The duration of the procedure, shortening of the radius, and the level of osteotomy were significantly better in Group 2. The three-dimensional procedural simulator seems to teach distal radius osteotomy better than a bone model and could be useful in teaching and learning bone surgery of the wrist.

    Cheung, Lawrence

    Educators are often tasked with developing courses and curricula that teach learners how to perform medical procedures. This instruction must provide an optimal, uniform learning experience for all learners. If not well designed, this instruction risks being unstructured, informal, variable amongst learners, or incomplete. This article shows how an instructional design model can help craft courses and curricula to optimize instruction in performing medical procedures. Educators can use this as a guide to developing their own course instruction.

    International Nuclear Information System (INIS)

    Goncharov, N.P.; Sufi, S.B.; Donaldson, A.; Jeffcoate, S.L.

    1986-01-01

    The Special Programme of Research, Development and Research Training in Human Reproduction of the World Health Organization has recognized from its beginning that training is a key component of its activities, including its immunoassay standardization programme. Since the start of the Special Programme more than 250 scientists have received training in RIA and related procedures and 27 training courses have been held in various countries. Many of the courses have been held in collaboration with the International Atomic Energy Agency, and these co-operative activities have established a core of scientific expertise worldwide which has contributed to the increased availability of modern diagnostic techniques in many countries. The increasing number of medical and non-medical applications of immunoassays and the special expertise required for some immunoassay methods create a continuing demand for training in RIA techniques. Both WHO and the IAEA have responded by organizing courses to 'train the trainers' and by supporting national and regional courses based on centrally provided material, as well as by commissioning the production of additional teaching documents and audio-visual aids in English and Spanish. It is envisaged that such materials, complete with centrally provided materials for practicals and other teaching aids, will be made available to national reagent programmes and will be used in the future as a well characterized, standardized core around which local organizers can construct training programmes geared to local needs and drawing upon local experience.

    2008-01-01

    The purpose of this study was to determine if a cognitive task analysis (CTA) could capture steps and decision points that were not articulated during traditional teaching of a colonoscopy. Three expert colorectal surgeons were videotaped performing a colonoscopy. After the videotapes were transcribed, the experts participated in a CTA. A 26-step procedural checklist and a 16-step cognitive demands table was created by using information obtained in the CTA. The videotape transcriptions were transposed onto the procedural checklist and cognitive demands table to identify steps and decision points that were omitted during traditional teaching. Surgeon A described 50% of "how-to" steps and 43% of decision points. Surgeon B described 30% of steps and 25% of decisions. Surgeon C described 26% of steps and 38% of cognitive decisions. By using CTA, we were able to identify relevant steps and decision points that were omitted during traditional teaching by all 3 experts.

    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.

    2007-01-01

    Aim: To evaluate the use of a phantom system to help teach the basic techniques of accurate CT-guided needle placement, thereby avoiding the risks associated with teaching on patients. Materials and Methods: Gelatine phantoms with five, 1.9 cm embedded spherical wooden targets were constructed. Four trainee operators performed 15 simulated biopsy procedures on the targets (series one) and repeated identical procedures 2 weeks later (series two). Statistical analysis of accuracy of needle placement and subject confidence were performed. Results: Significant sequential improvement in axial plane angular error was noted with the average error decreasing by 0.33 degrees after every five procedures performed (95% CI: -0.58 to -0.08, p = 0.01). Operator confidence indicated significant improvement both within each series and from series one to series two (95% CI: 0.08 to 1.17, p = 0.025 and 95% CI: 0.00 to 0.58, p = 0.05) respectively. However, variability in operator performance made statistically significant improvement in other variables unproven. Conclusion: Despite the study comprising a relatively small number of participants and procedures, it clearly demonstrated the effectiveness of teaching operators to perform CT-guided procedures using a phantom system. Needle placement accuracy significantly improved, with a reduction in axial angular error, and improved operator confidence without the risks associated with training on patients. Three of the operators in this study had never performed a CT-guided procedure previously, and their proficiency, after a relatively short but intense period of training, was impressive. The use of phantoms should be considered routinely for basic training of CT-guided needle placement

    2012-01-01

    In the spirit of closing the 'research-practice gap,' the authors extend evidence-based principles to statistics instruction in social science graduate education. The authors employ a Delphi method to survey experienced statistics instructors to identify teaching techniques to overcome the challenges inherent in teaching statistics to students enrolled in practitioner-oriented master's degree programs. Among the teaching techniques identi?ed as essential are using real-life examples, requiring data collection exercises, and emphasizing interpretation rather than results. Building on existing research, preliminary interviews, and the ?ndings from the study, the authors develop a model describing antecedents to the strength of the link between research and practice.

    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.

    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.

    Because of its high requirements on surgical experience and the need of complete understanding of the anatomy, oral surgery and especially implantology belong to the most demanding procedures in dentistry. Therefore, hands-on courses for oral surgery and implantology are considered a prerequisite to prepare for clinical practice. To achieve teaching conditions as realistic as possible, we used a novel human cadaver embalming method enabling tissue dissection comparable with the living body. Thirty cadavers which were offered by the Institute of Anatomy for the purpose of running oral surgery and implantology courses were embalmed in the technique described by Thiel. On each cadaver, dissection of soft and hard tissue and implantological procedures were performed according to a structured protocol by each course participant. The conservation of fine anatomical structures and the suitability of the embalmed tissue for dissecting, drilling, and suturing were observed and photographically documented. By means of the Thiel embalming technique, oral surgery and implantological procedures could be performed under realistic conditions similar to the living body. Due to the conservation procedure, preparations could be carried out without any time limit, always maintaining the same high quality of the tissue. The maxillary sinus membrane, mucosa, bone, and nerves could be exposed and allowed dissecting, drilling, and suturing even after weeks like fresh specimens. The Thiel embalming method is a unique technique which is ideally suited to practice and teach oral surgery and implantology on human material. © 2009 Wiley Periodicals, Inc.

    2015-07-01

    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.

    Cheng, Yu-Tsun; Liu, Deborah R; Wang, Vincent J

    2017-03-01

    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 < 0.0001), had higher pass rates (73%; 95% CI, 53%-93% vs 0%; P < 0.0001), and required less time (minutes) for presplinting preparation (mean [SD], 7.86 [2.45]; 95% CI, 6.78-8.94 vs mean [SD], 9.89 [0.46]; 95% CI, 9.67-10.12; P < 0.0001) compared with the control group. No difference was seen in the time required to complete a splint, successful or not. In comparison with reading standard textbooks, watching a brief JITT instructional video before splinting yielded faster learning times combined with more successful procedural skills. The use of a JITT instructional video may have potential applications, including globally, as an alternative resource for teaching and disseminating procedural skills, such as SA volar splinting.

  14. Multiparous Ewe as a Model for Teaching Vaginal Hysterectomy Techniques.

    Kerbage, Yohan; Cosson, Michel; Hubert, Thomas; Giraudet, Géraldine

    2017-12-01

    Despite being linked to improving patient outcomes and limiting costs, the use of vaginal hysterectomy is on the wane. Although a combination of reasons might explain this trend, one cause is a lack of practical training. An appropriate teaching model must therefore be devised. Currently, only low-fidelity simulators exist. Ewes provide an appropriate model for pelvic anatomy and are well-suited for testing vaginal mesh properties. This article sets out a vaginal hysterectomy procedure for use as an education and training model. A multiparous ewe was the model. Surgery was performed under general anesthesia. The ewe was in a lithotomy position resembling that assumed by women on the operating table. Two vaginal hysterectomies were performed on two ewes, following every step precisely as if the model were human. Each surgical step of vaginal hysterectomy performed on the ewe and on a woman were compared side by side. We identified that all surgical steps were particularly similar. The main limitations of this model are costs ($500/procedure), logistic problems (housing large animals), and public opposition to animal training models. The ewe appears to be an appropriate model for teaching and training of vaginal hysterectomy.

  15. Calibration and verification of surface contamination meters --- Procedures and techniques

    2007-03-01

    A standardised measurement procedure for surface contamination meters (SCM) is presented. The procedure aims at rendering surface contamination measurements to be simply and safely interpretable. Essential for the approach is the introduction and common use of the radionuclide specific quantity 'guideline value' specified in the Swiss Radiation Protection Ordinance as unit for the measurement of surface activity. The according radionuclide specific 'guideline value count rate' can be summarized as verification reference value for a group of radionuclides ('basis guideline value count rate'). The concept can be generalized for SCM of the same type or for SCM of different types using he same principle of detection. A SCM multi source calibration technique is applied for the determination of the instrument efficiency. Four different electron radiation energy regions, four different photon radiation energy regions and an alpha radiation energy region are represented by a set of calibration sources built according to ISO standard 8769-2. A guideline value count rate representing the activity per unit area of a surface contamination of one guideline value can be calculated for any radionuclide using instrument efficiency, radionuclide decay data, contamination source efficiency, guideline value averaging area (100 cm 2 ), and radionuclide specific guideline value. n this way, instrument responses for the evaluation of surface contaminations are obtained for radionuclides without available calibration sources as well as for short-Iived radionuclides, for which the continuous replacement of certified calibration sources can lead to unreasonable costs. SCM verification is based on surface emission rates of reference sources with an active area of 100 cm 2 . The verification for a given list of radionuclides is based on the radionuclide specific quantity guideline value count rate. Guideline value count rates for groups of radionuclides can be represented within the maximum

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

    Because of its high requirements on dexterity and microsurgical skills and the need of complete understanding of flap anatomy, microvascular free flap transfer belongs to the most demanding surgical procedures. Therefore, courses for flap raising and microvascular exercise are considered a prerequisite to prepare for clinical practise. To achieve teaching conditions as realistic as possible we used a novel cadaver embalming method enabling tissue dissection comparable to the living body. Thirty cadavers which were offered to us by the Institute of Anatomy for the purpose of running flap raising courses were embalmed in the technique described by Thiel. On each cadaver, nine free flaps were dissected according to a structured protocol by each course participant and afterwards used for microvascular exercise. The conservation of fine vascular structures and the suitability of the embalmed tissue for microvascular suturing were observed and photographically documented. The Thiel embalming technique provided flap raising procedures to be performed under realistic conditions similar to the living body. Vessels and nerves could be exposed and dissected up to a diameter of 1 mm and allowed for microvascular suturing even after weeks like fresh specimens. The Thiel embalming method is a unique technique and ideally suited to teach flap raising and microvascular suturing on human material. (c) 2008 Wiley-Liss, Inc. Microsurgery, 2008

    For science education, it is important to demonstrate to students the relevance of scientific concepts in every-day life experiences. Although there are methods available for achieving this goal, it is more effective if cultural flavor is also added to the teaching techniques and thereby the teacher and students can easily relate the subject matter to their surroundings. Furthermore, this would bridge the gap between science and day-to-day experiences in an effective manner. It could also help students to use science as a tool to solve problems faced by them and consequently they would feel science is a part of their lives. In this paper, it has been described how simple models and cultural communication techniques can be used effectively in demonstrating important scientific concepts to the students of secondary and higher secondary levels by using two consecutive activities carried out at the Institute of Fundamental Studies (IFS), Sri Lanka.

    2016-12-01

    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.

    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 FaceTime, iPhone5 as the devise in isolate site was optimum compared with iPod Touch and iPhone4.

    DSA remains the gold standard imaging method for the evaluation of many cerebrovascular disorders, in particular cerebral aneurysms and vascular malformations. The purpose of this study was to demonstrate the effect of modifying DSA frame rate, fluoroscopic and roadmap pulse rates, and flat panel detector (FPD) position on the radiation dose delivered during routine views for a cerebral angiogram in a phantom model. Adult skull and abdomen/pelvis anthropomorphic phantoms were used to compare the radiation dose metrics Ka,r (in mGy), PKA (in μGym(2)), and fluoroscopy time (in minutes) after modification of fluoroscopic pulses per second (p/s), DSA frames per second (f/s), and FPD position and collimation in three components of a cerebral angiogram: (1) femoral artery access, (2) roadmap guidance, and (3) biplane cerebral DSA. For femoral artery access, DSA protocols resulted in significantly higher doses than those utilizing fluoroscopy alone (p=0.007). Roadmaps using 3 p/s or 4 p/s delivered significantly less dose than higher pulse rates (p=0.008). The ranges of delivered doses for biplane cerebral DSA were 347.3-1188.5 mGy and 3914.54-9518.78 μGym(2). The lowest radiation doses were generated by the variable frame rate DSA protocols. Replacing femoral arterial access evaluations by DSA with fluoroscopy, utilizing lower pulse rates during fluoroscopy and roadmap guidance, and choosing variable frame rates for DSA are simple techniques that may be considered by operators in their clinical practices to lower radiation dose during cerebral angiography procedures.

    Medical students have limited confidence in performing procedural skills. A pilot study was conducted to evaluate the effect of a multifaceted Procedural Skills Lab (PSL) on the confidence of medical students to perform procedural skills. Twelve 2nd year medical students were randomly selected to participate in a pilot PSL. The PSL students met with an instructor for 2 h once a week for 4 weeks. Students participated in a flipped classroom and spaced education program before laboratory sessions that included a cadaver laboratory. Procedural skills included a focused assessment with sonography in trauma (FAST) scan, cardiac echocardiogram, lumbar puncture, arthrocentesis, and insertion of intraosseous and intravenous catheters. Students in the PSL were asked to rank their confidence in performing procedural skills before and after completion of the laboratory sessions (Wilcoxon ranked-sum test). A web-based questionnaire was also emailed to all 2nd year medical students to establish a baseline frequency for observing, performing, and confidence performing procedural skills (Mann-Whitney U-test). Fifty-nine percent (n = 106) of 180 2nd year medical students (n = 12 PSL students [treatment group], n = 94 [control group]) completed the survey. Frequency of observation, performance, and confidence in performing procedural skills was similar between the control and treatment groups at baseline. There was an increased confidence level (p skills for the treatment group after completion of the PSL. An innovative PSL may increase students' confidence to perform procedural skills. Future studies will examine competency after a PSL.

    A family medicine residency is a unique training environment where residents are exposed to care in multiple settings, across all ages. Procedures are an integral part of family medicine practice. Family medicine residency (FMR) programs are tasked with the job of teaching these skills at a level of intensity and frequency that allows a resident to achieve competency of such skills. In an environment that is limited by work hour restrictions, self-study teaching methods are one way to ensure all residents receive the fundamental knowledge of how to perform procedures. We developed and evaluated the efficacy of a self-study procedure teaching method and procedure evaluation checklist. A self-study procedure teaching intervention was created, consisting of instructional articles and videos on three procedures. To assess the efficacy of the intervention, and the competency of the residents, pre- and postintervention procedure performance sessions were completed. These sessions were reviewed and scored using a standardized procedure performance checklist. All 24 residents participated in the study. Overall, the resident procedure knowledge increased on two of the three procedures studied, and ability to perform procedure according to expert-validated checklist improved significantly on all procedures. A self-study intervention is a simple but effective way to increase and improve procedure training in a way that fits the complex scheduling needs of a residency training program. In addition, this study demonstrates that the procedure performance checklists are a simple and reliable way to increase assessment of resident procedure performance skills in a residency setting.

    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.

    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

    In response to the growing body of evidence that simulation is a satisfactory way to instruct procedural skills, we developed an innovative model to teach common gynecologic procedures such as cervical cancer screening, cervical polyp removal, intrauterine device removal, and endometrial biopsy. The objectives of this study were to describe the construction of the model and to assess participants' satisfaction and confidence in applying the learning objectives to their clinical practice. The researchers created the model with reusable and readily available materials. During a hands-on skills workshop, practicing clinicians performed simulated cervical cancer screening, endocervical polyp removal, intrauterine device removal, and an endometrial biopsy on a low-fidelity gynecologic model. Using convenience sampling, each participant completed a survey designed to measure satisfaction with the workshop and self-confidence in their newly acquired skills. All (N = 30,100%) of the participants agreed at the "agree" or "strongly agree" level that the gynecologic skills workshop using lecture and a hands-on model was a satisfying and self-confidence-building experience. An easily reproducible and reusable gynecologic procedure simulator was highly rated as a means of teaching common primary care gynecologic procedures. The simulated model provided an opportunity for hands-on skills learning for clinicians who wish to expand their gynecologic procedure skill set.

One of the effective techniques for teaching a main procedural skill is to deconstruct the skill into a series of microskills and train students on each microskill separately. When we learn microskills, we will learn the main skill also. This model can be beneficial for tuition on procedural skills.Objective: In this study, we propose a stationed-based deconstructed training model for tuition of each microskill, and then we assessed the medical students’ self-perceived abilities.Methods: This quasi-experimental study was conducted in 268 medical students (536 matched pre- and post-questionnaires at the surgical clerkship stage during five consecutive years in three teaching and learning groups. In this study, we taught each skill in 10 steps (proposed model to the students. We then evaluated the students’ self-perceived abilities using a pre- and post-self-assessment technique. SPSS v13 software with one-way analysis of variance and paired t-tests were used for data collection and analysis.Results: Assessment of medical students’ perceived abilities before and after training showed a significant improvement (P < 0.001 in both cognitive and practical domains. There were also significant differences between the three teaching and learning groups (P < 0.001. There were no significant differences for the different years of training regarding the observed improvement.Conclusion: This study suggests that deconstructing the practical skills into microskills and tuition of those microskills via the separated structured educational stations is effective according to the students’ self

    the teaching of gross anatomy to first-year medical students has progressed from a 'stand-alone' discipline to one with much clinical emphasis. The curriculum at Loma Linda University School of Medicine has had increasing clinical correlates in recent years. We decided to supplement this with procedure demonstrations early in the course, and measure the student response. clinical procedures were performed on cadavers in the anatomy lab. For example, pleural and pericardial effusions were simulated by placing bags of intravenous fluid in the pleural and pericardial cavities; pneumothorax and tension pneumothorax were simulated using an inflatable rubber bladder. Videos were made and then presented in sequence with gross anatomy lectures. The student response was evaluated with a survey sheet. the Student response was overwhelmingly positive, with all students stating that the presentations made anatomy more relevant, and most indicating that anatomy also became easier to learn. Feedback confirmed that first-year medical students have a strong clinical orientation, which can facilitate both the teaching and learning of gross anatomy. advantages of having clinicians present simulated procedures in the anatomy lab include: heightened student interest; mentoring and modelling for students; introduction to clinical concepts now encountered in basic science examinations; supplementation of the thinning ranks of qualified gross anatomy teachers. The use of intravenous fluid bags and distensible bladders to simulate abnormal collections of fluid and air in body cavities is simple, inexpensive, and can be replicated in any anatomy lab.

    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

    To determine the benefit of the addition of low-fidelity simulation-based training to the standard didactic-based training in teaching radiology residents common CT-guided procedures. This was a prospective study involving 24 radiology residents across all years in a university program. All residents underwent standard didactic lecture followed by low-fidelity simulation-based training on three common CT-guided procedures: random liver biopsy, lung nodule biopsy, and drain placement. Baseline knowledge, confidence, and performance assessments were obtained after the didactic session and before the simulation training session. Approximately 2 months later, all residents participated in a simulation-based training session covering all three of these procedures. Knowledge, confidence, and performance data were obtained afterward. These assessments covered topics related to preprocedure workup, intraprocedure steps, and postprocedure management. Knowledge data were collected based on a 15-question assessment. Confidence data were obtained based on a 5-point Likert-like scale. Performance data were obtained based on successful completion of predefined critical steps. There was significant improvement in knowledge (P = .005), confidence (P training to the standard didactic curriculum for all procedures. This study suggests that the addition of low-fidelity simulation-based training to a standard didactic-based curriculum is beneficial in improving resident knowledge, confidence, and tested performance of common CT-guided 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

    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.

    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.

    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. Copyright © 2011 American Society of PeriAnesthesia Nurses.

    This paper presents a workflow to increase the level of detail of reality-based 3D urban models. It combines the established workflows from photogrammetry and procedural modeling in order to exploit distinct advantages of both approaches. The combination has advantages over purely automatic acquisition in terms of visual quality, accuracy and model semantics. Compared to manual modeling, procedural techniques can be much more time effective while maintaining the qualitative properties of the modeled environment. In addition, our method includes processes for procedurally adding additional features such as road and rail networks. The resulting models meet the increasing needs in urban environments for planning, inventory, and analysis

    Central venous catheterization is commonly performed in clinical practice. Traditional procedural technique is based on anatomical landmarks, but is associated with a high risk of failure and complications. To decrease their incidence European and American societies recommend application of ultrasonography. Preliminary ultrasonographic examination allows for assessment of local anatomical relations as well as vessel morphology (diameter, patency), while real-time ultrasonography increases chances of successful needle insertion. This paper presents the most common venous access sites and procedure techniques. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

  5. Stylistic features of narrative procedure in a psychological short story in the context of teaching interpretation

    Directory of Open Access Journals (Sweden)

    Stakić Mirjana M.

    2016-01-01

    Full Text Available The paper investigates the stylistic features of narrative procedure in a psychological short story in the context of its interpretation in the teaching of the Serbian language and literature. The narrative procedure in a psychological short story is characterized by the use of the first person in narrating, that is I form, an interior monologue and direct interior monologue, dreams, oversights and introspective. It is also characterized by a particular sentence structure, of often incomplete and elliptical form, used to express the conflicts going on in characters' inner sphere and verbal interaction between the characters. The narrative procedure applied in a psychological short story indicates that its plot is subdued to the internal psychological experiences. During the interpretation of a psychological short story students, through the interpretation of stylistic and narrative procedures, are directed and encouraged to discover complex and often hidden psychological mechanisms which spur the characters to act, influence their behavior, verbal expression and mutual relations. The interpretation of language signs which may have psychological and semantic potential leads to the revealing of unconscious internal psychological processes and mechanisms which take place within a literary character.

    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.

    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.

    Endoscopic sutured gastroplasty (ESG) has evolved over time. With the advent of full-thickness endoscopic suturing, an efficient technique for ESG was developed and refined. This prospective first-in-man trial started in April 2012 and represents the first use of full-thickness endoscopic suturing for primary obesity therapy. The trial focused on procedure development, reproducibility, safety, and short-term efficacy. The trial was performed at centers in five countries, in three phases. Phase I was evaluation of safety and technical feasibility of various procedure techniques; stitch patterns and sequences were assessed for efficiency, safety, and feasibility. Phase II entailed continued procedure refinement to establish a standardized technique. Phase III entailed evaluation of technical feasibility and weight loss outcomes in 77 patients; the procedure was performed using the standardized technique, and there was no procedure development. Data were prospectively collected into a registry. In Phase I, the procedure was created and modified to improve time efficiency. Safety and technical feasibility were established, and short-term weight loss was demonstrated. In Phase II, a number of stitch patterns were attempted, and the stitch pattern was modified and finalized. 22 patients were included, and 1-year total weight loss was 17.3 ± 2.6%. In Phase III, conformity with the final technique was high. 77 patients were included, with a mean BMI of 36.1 ± 0.6 kg/m 2 . Mean weight loss was 16.0 ± 0.8% at 6 months and 17.4 ± 1.2% at 12 months (n = 44). Postprocedural nausea, vomiting, and epigastric pain were frequently reported; there were no reported significant adverse events post-procedure or during the follow-up period. Following a methodical procedure development phase, ESG demonstrated safety and short-term efficacy in this trial. The procedure also achieved meaningful weight loss during the follow-up period.

    Full Text Available Zakaria Messieha Department of Anesthesiology, University of Illinois at Chicago, Chicago, IL, USA Abstract: Ambulatory surgical and anesthesia care (ASAC, also known as Same Day Surgery or Day Care in some countries, is the fastest growing segment of ambulatory surgical and anesthesia care. Over 50 million ambulatory surgical procedures are conducted annually comprising over 60% of all anesthesia care with an impressive track record of safety and efficiency. Advances in ambulatory anesthesia care have been due to newer generation of inhalation and intravenous anesthetics as well as airway management technology and techniques. Successful ambulatory anesthesia care relies on patient selection, adequate facilities, highly trained personnel and quality improvement policies and procedures. Favoring one anesthetic technique over the other should be patient and procedure-specific. Effective management of post-operative pain as well as nausea and vomiting are the final pieces in assuring success in ambulatory anesthesia care.

    2017-06-01

    Full Text Available In today’s generation of digital natives, students find it unexciting to sit down and read literary texts in its entirety. Thus, students nowadays hardly understand and appreciate literature as a subject. This calls for additional challenge to teachers who had been used to deliver their lessons or any subject matter in traditional ways. This study used descriptive-correlational research design to unveil the most effective viewing teaching techniques that will help develop the viewing comprehension skills of literature students in a tertiary level. Findings reveal how literature students perceive the use of movies or videos as a powerful viewing teaching technique. Result of chi-square test of independence indicates the viewing teaching techniques are not significantly related to students’ viewing comprehension. This suggests that no single teaching technique suits the learners’ interest and ability to learn. Therefore, teachers can make use of technology combined with other viewing techniques to ensure that students will find a love for literature that will help establish their academic success in the future.

    Full Text Available A restricted mouth opening in hemimaxillectomy patient can create a significant problem with the insertion and the removal of the obturator prosthesis. Even it poses a problem in impression making due to small oral opening. A modification of the standard impression procedure is often necessary to accomplish an acceptable impression in the fabrication of a successful prosthesis. Sectional trays are a good option for such patients. This paper describes a novel technique of impression procedure and a method of fabricating a sectional tray with the anterior and the posterior locking mechanism for a hemimaxillectomy patient with limited oral opening.

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

    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.

    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.

    1985-01-01

    The high sensitivity of the pre-dose TL technique using fired quartz grains with relatively low doses makes it the only TL technique that is generally suitable for retrospective environmental dosimetry. The use of this technique for dose measurements of less than 0.2 Gy has been the focus of research at the Utah laboratory, while the extension of the useful range of the pre-dose technique to doses in excess of 5 Gy has been the aim of the Durham laboratory. Certain characteristics of the pre-dose phenomenon, if not properly diagnosed, can lead to erroneous dose estimates at both extremes. This paper describes the procedures used at both laboratories to diagnose such problems and recently developed methods for their circumvention. (author)

    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. © 2017 Society of Hospital Medicine

    2012-01-01

    The aim of this report is to describe an alternative technique to record the neutral zone. An acrylic resin base with posterior occlusal rims was applied using a thermoplastic denture adhesive. After being worn for 2 days, the base was transferred into an acrylic resin complete denture. Most patients reported an improvement in denture stability and a reduction of pressure sores. This procedure seems to be helpful to improve denture function, especially in the mandible, in patients who cannot be treated with implants. However, because of its complexity, this neutral zone technique cannot be recommended for routine clinical use.

    Vertebroplasty and kyphoplasty can be associated with significant radiation exposure to the operator. We compared the exposure levels to an operator performing vertebral fracture augmentation with vertebroplasty and kyphoplasty, to assess a cement injection and a monitoring technique designed to reduce this exposure. A neuroradiologist performed 189 consecutive vertebral augmentation procedures in 135 patients with osteoporotic compression fractures by using a bilateral approach with biplane pulse fluoroscopy at 7.5 pulses/second. Cement delivery was performed with intermittent fluoroscopy with kyphoplasty and vertebroplasty by using syringes or continuous fluoroscopic monitoring with a cement delivery system (CDS). Data collection included time and operator exposure parameters. A total of 87 kyphoplasty procedures, 82 vertebroplasty procedures with a CDS (VP-CDS), and 20 vertebroplasty procedures with syringes (VP-S) were safely performed. Mean fluoroscopy time for device positioning was 4.3 minutes for each procedure type. Mean fluoroscopy time (minutes) for cement delivery was significantly different for the 3 procedure types; 2.1 for kyphoplasty, 3.7 for VP-CDS, and 1.5 for VP-S (P exposure rates (microsieverts/minute) were 0.8 for kyphoplasty, 1.1 for VP-CDS, and 0.3 for VP-S during device-positioning and 1.7 for kyphoplasty, 2.9 for VP-CDS, and 0.2 for VP-S during cement injection (P technique and intermittent fluoroscopy with kyphoplasty and vertebroplasty with syringes results in a significantly lower operator exposure rate compared with vertebroplasty with a CDS.

    Zhang, Chuanbao; Zhao, Haijian; Wang, Jing; Zeng, Jie; Wang, Zhiguo

    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 QGIs were further calculated. Based on QGI values, 8.6% (5/58, AMY) to 35.9% (28/78, LDH) of the laboratories (QGI < 0.8) need to improve the precision of the procedures, 8.0% (6/75, CK) to 52.6% (40/76, ALP) of the laboratories (QGI ≤ 1.2) need to improve the trueness of the procedures; and 2.7% (2/75, AST) to 16.3% (8/49, GGT) of the laboratories (0.8 ≤ QGI ≤ 1.2) need to improve both the precision and trueness of the procedures. Even though rapid progress has been made to standardize serum enzyme measurements in China in recent years, our study using Six Sigma techniques still suggested that

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

    Jorge Felipe Ramírez León

    Full Text Available ABSTRACT Objective: To report the outcomes of non-endoscopic percutaneous cervical discectomy by anterior blunt approach for the treatment of degenerative disc disease. Methods: A review of the medical records of patients with axial cervical pain resulting from degenerative disc disease and treated with discectomy and percutaneous nucleoplasty by anterior blunt approach with radiofrequency source was carried out. The data were evaluated according to modified MacNab and pre- and postoperative VAS criteria at 3, 12 and 24 months. Results: Sixty-two procedures were performed in 48 patients between 2008 and 2014. The mean age of the population was 52.4 years. MacNab results were 84.6%, 92.3%, and 89.2% improvement (excellent and good results at 3, 12 and 24 months, respectively. The VAS changed from 7.4 to 2.3 two years after the procedure, showing a statistically significant difference (p=0.000. There were no major complications or re-interventions related to the technique. Conclusions: Anterior non-endoscopic discectomy and nucleoplasty for the treatment of discogenic axial cervical pain may be an effective alternative to open surgery. In the two-year follow-up, our blunt technique proved to be a safe procedure with no approach-related complications, and provided outcomes comparable to those reported using the original needle technique.

    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.

    The aim of this survey was to evaluate the current practice regarding pain assessment and pain management strategies adopted in commonly performed minor painful procedures in Northern Italian Neonatal Intensive Care Units (NICUs). A multicenter survey was conducted between 2008 and 2009 in 35 NICUs. The first part of the survey form covered pain assessment tools, the timing of analgesics, and the availability of written guidelines. A second section evaluated the analgesic strategies adopted in commonly performed painful procedures. The listed analgesic procedures were as follows: oral sweet solutions alone, non-nutritive sucking (NNS) alone, a combination of sweet solutions and NNS, breast-feeding where available, and topical anesthetics. Completed questionnaires were returned from 30 neonatal units (85.7% response rate). Ten of the 30 NICUs reported using pain assessment tools for minor invasive procedures. Neonatal Infant Pain Scale was the most frequently used pain scale (60%). Twenty neonatal units had written guidelines directing pain management practices. The most frequently used procedures were pacifiers alone (69%), followed by sweet-tasting solutions (58%). A 5% glucose solution was the most frequently utilized sweet-tasting solution (76.7%). A minority of NICUs (16.7%) administered 12% sucrose solutions for analgesia and the application of topical anesthetics was found in 27% of NICUs while breast-feeding was performed in 7% of NICUs. This study found a low adherence to national and international guidelines for analgesia in minor procedures: the underuse of neonatal pain scales (33%), sucrose solution administration before heel lance (23.3%), topical anesthetics before venipuncture, or other analgesic techniques. The presence of written pain control guidelines in these regions of Northern Italy increased in recent years (from 25% to 66%). © 2010 World Institute of Pain.

    2016-08-01

    Chronic and acute shoulder pain and dysfunction are common complaints among patients. Shoulder pain may be the result of abnormality involving the rotator cuff, subacromial-subdeltoid bursa, biceps tendon, glenoid labrum, glenohumeral joint, acromioclavicular joint, sternoclavicular joint, or glenohumeral joint capsule. Ultrasound-guided (USG) procedures of the shoulder are well established for interventional management. Ultrasound provides the advantages of excellent soft tissue resolution, injection accuracy, low cost, accessibility, portability, lack of ionizing radiation, and the ability to perform real-time image-guided procedures. The purpose of this article is to review common indications and effective techniques for USG injections about the shoulder. Copyright © 2016 Elsevier Inc. All rights reserved.

    2015-12-01

    Skinfold assessment is valid and economical; however, it has a steep learning curve, and many programs only include one exposure to the technique. Increasing the number of exposures to skinfold assessment within an undergraduate curriculum would likely increase skill proficiency. The present study combined observational and Think Aloud methodologies to quantify procedural and cognitive characteristics of skinfold assessment. It was hypothesized that 1) increased curricular exposure to skinfold assessment would improve proficiency and 2) the combination of an observational and Think Aloud analysis would provide quantifiable areas of emphasis for instructing skinfold assessment. Seventy-five undergraduates with varied curricular exposure performed a seven-site skinfold assessment on a test subject while expressing their thoughts aloud. A trained practitioner recorded procedural observations, with transcripts generated from audio recordings to capture cognitive information. Skinfold measurements were compared with a criterion value, and bias scores were generated. Participants whose total bias fell within ±3.5% of the criterion value were proficient, with the remainder nonproficient. An independent-samples t-test was used to compare procedural and cognitive observations across experience and proficiency groups. Additional curricular exposure improved performance of skinfold assessment in areas such as the measurement of specific sites (e.g., chest, abdomen, and thigh) and procedural (e.g., landmark identification) and cognitive skills (e.g., complete site explanation). Furthermore, the Think Aloud method is a valuable tool for determining curricular strengths and weaknesses with skinfold assessment and as a pedagogical tool for individual instruction and feedback in the classroom.

    2010-01-01

    Class V restorations are a very common occurrence in clinics. Some reasons include an increase in non-carious cervical lesions (NCCL), root caries and the elderly population. Unfortunately, Class V restorations also represent one of the less durable types of restorations and have a high index of loss of retention, marginal excess and secondary caries. Some causes for these problems include difficulties in isolation, insertion, contouring, finishing and polishing procedures. This technique demonstrates an alternative isolation and insertion method using photocured gingival barrier in association with a flowable resin and hybrid resin composite to recreate the gingival wall with minimum or no excess.

    1986-05-01

    The reconstruction formulations of multiple-frequency-holography (MFH) and SAFT procedures used in ultrasonic NDE are investigated analytically and shown to be closely related, and experimental measurements on a steel block with a 6-mm-diameter 45.5-mm hole are reported. The results are presented in graphs and shown to be in good agreement with the theoretical models proposed. The limitations of these methods in discriminating the nonlinear upper edge of the hole are indicated, and it is suggested that simpler methods such as the shadow-holography technique described by Kutzner and Zimpfer (1977) may be more useful in some cases.

    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 37 ºC 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.

    Laypersons often hesitate to perform basic life support (BLS) and use an automated external defibrillator (AED) because of self-perceived lack of knowledge and skills. Training may reduce the barrier to intervene. Reduced training time and costs may allow training of more laypersons. The aim of this study was to compare BLS/AED skills' acquisition and self-evaluated BLS/AED skills after instructor-led training with a two-stage versus a four-stage teaching technique. Laypersons were randomized to either two-stage or four-stage teaching technique courses. Immediately after training, the participants were tested in a simulated cardiac arrest scenario to assess their BLS/AED skills. Skills were assessed using the European Resuscitation Council BLS/AED assessment form. The primary endpoint was passing the test (17 of 17 skills adequately performed). A prespecified noninferiority margin of 20% was used. The two-stage teaching technique (n=72, pass rate 57%) was noninferior to the four-stage technique (n=70, pass rate 59%), with a difference in pass rates of -2%; 95% confidence interval: -18 to 15%. Neither were there significant differences between the two-stage and four-stage groups in the chest compression rate (114±12 vs. 115±14/min), chest compression depth (47±9 vs. 48±9 mm) and number of sufficient rescue breaths between compression cycles (1.7±0.5 vs. 1.6±0.7). In both groups, all participants believed that their training had improved their skills. Teaching laypersons BLS/AED using the two-stage teaching technique was noninferior to the four-stage teaching technique, although the pass rate was -2% (95% confidence interval: -18 to 15%) lower with the two-stage teaching technique.

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

    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.

    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.

  18. 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.

    Full Text Available Background: A correct selection of drugs prescribed, but also the choice of the appropriate inhaler device, is crucial for the control of respiratory diseases. Objective: To evaluate the inhaler technique and identify potential errors of patients when treated with inhalers by testing a routinary procedure to be implemented in any community pharmacy. Methods: Adults with asthma/COPD and under inhalation therapy were invited to demonstrate how they use their inhalers. After direct observation it was registered whether all the sequential steps included in the summary of product characteristics (SmPC were performed. Results: The study involved 67 patients from 4 community pharmacies (Portugal central region: 34 (50.7% males, 65.4 (SD=18.28 years old, 42 (62.7% with COPD, and 23 (34.3% using more than one inhaler. The 67 patients used 95 inhalers, comprising: 57 (60.0% multiple dose DPI (dry powder inhalers, 18 (18.9% single dose DPI, 16 (16.8% pMDI (pressurized metered dose inhalers, 2 (2.1% pMDI+spacer and 2 (2.1% SMI (soft mist inhalers. No errors were made only by 9 (13.4% patients. In the 75 DPIs techniques, the most frequent errors were ‘no previous forced expiration’ (46=61.3% and ‘no 10s apnea after inhalation’ (51=68.0%; in the 16 pMDIs techniques common errors were ‘lack of hand-lung coordination’ (7=43.8 %, ‘no previous forced exhalation’ (8=50.0% and ‘no apnea after inhalation’ (10=62.5%. After inhaling from 56 devices containing corticosteroids, 34 (60.7% of the patients did not wash their mouth. Conclusion: The study demonstrated the possibility of performing this procedure routinely in Portuguese community pharmacies and also its utility, since 58 (87% of patients had at least one error during the inhalers use.

  20. Monti’s procedure as an alternative technique in complex urethral distraction defect

    2010-06-01

    Full Text Available PURPOSE: Pelvic fracture urethral distraction defect is usually managed by the end to end anastomotic urethroplasty. Surgical repair of those patients with post-traumatic complex posterior urethral defects, who have undergone failed previous surgical treatments, remains one of the most challenging problems in urology. Appendix urinary diversion could be used in such cases. However, the appendix tissue is not always usable. We report our experience on management of patients with long urethral defect with history of one or more failed urethroplasties by Monti channel urinary diversion. MATERIALS AND METHODS: From 2001 to 2007, we evaluated data from 8 male patients aged 28 to 76 years (mean age 42.5 in whom the Monti technique was performed. All cases had history of posterior urethral defect with one or more failed procedures for urethral reconstruction including urethroplasty. A 2 to 2.5 cm segment of ileum, which had a suitable blood supply, was cut. After the re-anastomosis of the ileum, we closed the opened ileum transversely surrounding a 14-16 Fr urethral catheter using running Vicryl sutures. The newly built tube was used as an appendix during diversion. RESULTS: All patients performed catheterization through the conduit without difficulty and stomal stenosis. Mild stomal incontinence occurred in one patient in the supine position who became continent after adjustment of the catheterization intervals. There was no dehiscence, necrosis or perforation of the tube. CONCLUSION: Based on our data, Monti’s procedure seems to be a valuable technique in patients with very long complicated urethral defect who cannot be managed with routine urethroplastic techniques.

    Multiple previous studies have shown that having a large diversity of procedures has a substantial impact on quality management of hospital surgical suites. At hospitals with substantial diversity, unless sophisticated statistical methods suitable for rare events are used, anesthesiologists working in surgical suites will have inaccurate predictions of surgical blood usage, case durations, cost accounting and price transparency, times remaining in late running cases, and use of intraoperative equipment. What is unknown is whether large diversity is a feature of only a few very unique set of hospitals nationwide (eg, the largest hospitals in each state or province). The 2013 United States Nationwide Readmissions Database was used to study heterogeneity among 1981 hospitals in their diversities of physiologically complex surgical procedures (ie, the procedure codes). The diversity of surgical procedures performed at each hospital was quantified using a summary measure, the number of different physiologically complex surgical procedures commonly performed at the hospital (ie, 1/Herfindahl). A total of 53.9% of all hospitals commonly performed complex procedures (lower 99% confidence limit [CL], 51.3%). A total of 14.2% (lower 99% CL, 12.4%) of hospitals had >3-fold larger diversity (ie, >30 commonly performed physiologically complex procedures). Larger hospitals had greater diversity than the small- and medium-sized hospitals (P 30 procedures (lower 99% CL, 71.9% of hospitals). However, there was considerable variability among the large teaching hospitals in their diversity (interquartile range of the numbers of commonly performed physiologically complex procedures = 19.3; lower 99% CL, 12.8 procedures). The diversity of procedures represents a substantive differentiator among hospitals. Thus, the usefulness of statistical methods for operating room management should be expected to be heterogeneous among hospitals. Our results also show that "large teaching hospital

    Most hospitalized patients with asthma or chronic obstructive pulmonary disease misuse respiratory inhalers. An in-person educational strategy, teach-to-goal (TTG), improves inpatients' inhaler technique. To develop an effective, portable education intervention that remains accessible to hospitalized patients postdischarge for reinforcement of proper inhaler technique. A mixed methods approach at an urban academic hospital was used to iteratively develop, modify, and test a virtual teach-to-goal ™ (V-TTG ™ ) educational intervention using patient end-user feedback. A survey examined access and willingness to use technology for self-management education. Focus groups evaluated patients' feedback on access, functionality, and quality of V-TTG ™ . Forty-eight participants completed the survey, with most reporting having Internet access; 77% used the Internet at home and 82% used the Internet at least once every few weeks. More than 80% reported that they were somewhat or very likely to use V-TTG ™ to gain skills to improve their health. Most participants reported smartphone access (73%); half owned laptop computers (52%). Participants with asthma versus chronic obstructive pulmonary disease were more likely to own a smartphone, have a data plan, and have daily Internet use (P platform and delivery, Internet access, and technological literacy; functionality-usefulness, content, and teaching strategy; and quality-clarity, ease of use, length, and likability. V-TTG ™ is a promising educational tool for improving patients' inhaler technique, iteratively developed and refined with patient input. Patients in our urban, academic hospital overwhelmingly reported access to platforms and willingness to use V-TTG ™ for health education.

    Multicentric fibroadenomas, defined as multiple fibroadenomas located at different quadrants of the breast, occur in 10-20% of women with fibroadenoma. The surgical management of multicentric fibroadenomas may be troublesome for surgeons and patients. In this study, we report our preliminary experience using the "round block technique" in the management of women with multicentric fibroadenomas of the breast. Records of patients with breast diseases managed with the round block technique were searched for in the Changhua Christian Hospital oncoplastic breast surgery database. The patients' clinicopathologic characteristics, type of surgery, operation time, blood loss, and complications were recorded. The cosmetic outcome was evaluated by the patient and operating surgeon two months after the surgery. Twenty patients with multicentric fibroadenomas managed by the round block technique comprised the current study cohort. The mean age of the subjects was 36.5 ± 10.4 years. Twelve (60%) patients had tumors on one side of the breast, and eight (40%) had bilateral breast lesions. The average number of tumors removed was 3.3 ± 1.2 (range 2-6) per breast, and mean tumor size was 2.2 ± 0.5 cm. Three (15%) patients developed mild ecchymosis of the breast undergoing operation, which resolved spontaneously. One (5%) patient had partial nipple ischemia/necrosis due to 2 tumors excised near the nipple-areolar complex. The aesthetic results were evaluated as good in 19 (95%) patients and fair in 1 (5%). The round block technique is a useful oncoplastic procedure for the management of multicentric fibroadenomas excised at the same time.

    Postoperative irrigation after endoscopic sinus surgery and endoscopic modified Lothrop procedure is used to remove nasal crusts and to improve wound healing. To evaluate the optimal application protocol for irrigation of the frontal sinus, a prospective cadaver study was performed. An endoscopic modified Lothrop procedure and complete sphenoethmoidectomy were performed in 19 heads. Each was irrigated with a 1.5% solution of water and different colors using nasal spray and a squeeze bottle filled with 50, 100, and 200 mL. Intensity of local staining and percentage of area were documented using standardized videoendoscopy after irrigation in "bending over the sink" or "vertex to floor" position. Grading was performed by two independent observers for 23 anatomic regions, including the stained circumference of maxillary and frontal ostia. To evaluate the influence of the anatomy, acoustic rhinometry was performed. ANOVA was used to evaluate effects of application methods and head positions using GenStat 8.2 (Lawes Agricultural Trust, Rothamsted Experimental Station, Harpenden, U.K.) using an appropriate block structure. With regard to the frontal sinus, we were able to show clear superiority of the squeeze bottle technique filled with 200 mL and applied in the "vertex to floor position." In a relatively fit and flexible patient the vertex to floor position using a squeeze bottle technique is advocated. There may be some patients, however, for whom this position is not feasible. In these patients "bending over the sink," while inferior to the "vertex to floor" position, still ensures some irrigation of the frontal sinus.

  9. Palatal approach of anterior superior alveolar injection technique may not be potentially useful in periodontal procedures

    Pragathi Raghavendra Bhat

    2016-01-01

    Full Text Available Background: The palatal approach of anterior superior alveolar (P-ASA using WAND injection was reported to effectively provide a profound bilateral maxillary anesthesia of the soft tissue of anterior one-third of the palate and facial gingivae extending from canine to canine which lasted for more than an hour thus making it ideal for scaling root planing and minor periodontal procedures in the anterior maxilla. Our study suggests that the conventional P-ASA injection is of very short duration and the extent of anesthesia was not profound and consistent. This has not been reported earlier in the literature. Materials and Methods: Thirty-five cases (20 males and 15 females, who underwent scaling, root planing and minor periodontal surgical procedures such as abscess drainage, gingivectomy, and frenectomy in the maxillary anterior region in the age range of 19–45 years was assessed for the efficacy of the P-ASA injection. After the administration of the P-ASA injection, the subjective and the objective symptoms were used to evaluate the extent and duration of the anesthesia at 10, 15, and 20 min. Results: This study suggests that the conventional P-ASA injection technique does not provide anesthesia for more than 20 min. Wilcoxon matched pairs test was used to compare the effect of anesthesia at the different time intervals and the results were found to be statistically significant (P < 0.05. Conclusions: The conventional P-ASA injection technique is of very short duration and does not demonstrate effectiveness in periodontal surgery of the anterior maxilla.

    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.)

    Under used crops are those crop species which have high potential value in the supply of important raw material for secondary economy sector in food processing. The yield production of new Under used crops varieties can be used as an important input in food production process for export products. The optimum production cost can be minimized since the price of raw material supplied from agriculture sector is cheaper compared with the international markets. Agriculture output can be increased through the development of Under used crops using radiation mutagenesis and tracer technique for good agricultural practices. This paper work will discuss the development procedure of mutation induction method which includes irradiation of samples such as seeds of groundnut and in vitro shoots of banana using gamma rays and application of N-15 for nutrient use efficiency and screening of potential mutant lines with high yield and resistance to drought. These management practices using established procedures of water and nutrient use efficiency will be recommended to the growers. (author)

    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.

    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.

    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. 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. 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. We suggest that centers interested in learning POEM consider 26 procedures in animal models to master it before performing it in patients with achalasia.

    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.

  18. Effect of precipitation procedure and detection technique on particle size distribution of CaCO 3

    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.

    Noninvasive fetal electrocardiography (fECG), obtained positioning electrodes on the maternal abdomen, is important in safeguarding the life and the health of the unborn child. This study aims to provide a review of the state of the art of fECG, and includes a description of the parameters useful for fetus clinical evaluation; of the fECG recording procedures; and of the techniques to extract the fECG signal from the abdominal recordings. The fetus clinical status is inferred by analyzing growth parameters, supraventricular arrhythmias, ST-segment variability, and fetal-movement parameters from the fECG signal. This can be extracted from an abdominal recording obtained using one of the following two electrode-types configurations: pure-abdominal and mixed. Differently from the former, the latter also provides pure maternal ECG tracings. From a mathematical point of view, the abdominal recording is a summation of three signal components: the fECG signal (i.e., the signal of interest to be extracted), the abdominal maternal ECG (amECG), and the noise. Automatic extraction of fECG includes noise removal by abdominal signal prefiltration (0.5-45 Hz bandpass filter) and amECG cancellation. Differences among methods rely on different techniques used to extract fECG. If pure abdominal electrode configurations are used, fECG is extracted directly from the abdominal recording using independent component analysis or template subtraction. Eventually, if mixed electrode configurations are used, the fECG can be extracted using the adaptive filtering fed with the maternal ECG recorded by the electrodes located in the woman thorax or shoulder. © 2015 Wiley Periodicals, Inc.

  4. 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

Many of the difficulties encountered in early Navier-Stokes calculations were inherent not only in the choice of the different equations (accuracy), but also in the method of solution or choice of algorithm (convergence and stability, in the manner in which the dependent variables or discretized equations are related (coupling), in the manner that boundary conditions are applied, in the manner that the coordinate mesh is specified (grid generation), and finally, in recognizing that for many high Reynolds number flows not all contributions to the Navier-Stokes equations are necessarily of equal importance (parabolization, preferred direction, pressure interaction, asymptotic and mathematical character). It is these elements that are reviewed. Several Navier-Stokes and parabolized Navier-Stokes formulations are also presented.

    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.

    Practical training of the surgery resident is based on the companionship currently hampered in particular by the increase of the number of residents in training. We created a teaching tool to promote learning and validation of a technique of classic urologic surgery, inguinal orchidopexy. The objective is to evaluate the applicability and the relevance of this tool. The tool is a technical evaluation sheet made from reference documentation. The trainers evaluated the residents at 3 times of the semester (hetero-evaluation at 0, 3 and 6 months). Residents evaluated themselves monthly on the same items. Three trainers and 6 residents in surgery participated in the study between May and November 2013. The initial evaluation confirmed that the theoretical knowledge was acquired prior to the practical learning. The level of residents was very uneven at the beginning of the study but not at the end of the semester. The monthly evaluations gave a progressive and significant increase of notes. The notes of the intermediate and final hetero-evaluations rose gradually and they were always superior to those previous self-assessments (Ptool was considered simple and useful for the participants. This tool is applicable and relevant to the technical teaching of inguinal orchidopexy in this population. A larger study would be helpful to confirm it. This type of tool could be applied to the simple and common surgery techniques to enrich the educational tools used in the training. 4. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    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; P technique 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.

  15. Recommended procedures and techniques for the petrographic description of bituminous coals

    Science.gov (United States)

    1982-01-01

    Modern coal petrology requires rapid and precise description of great numbers of coal core or bench samples in order to acquire the information required to understand and predict vertical and lateral variation of coal quality for correlation with coal-bed thickness, depositional environment, suitability for technological uses, etc. Procedures for coal description vary in accordance with the objectives of the description. To achieve our aim of acquiring the maximum amount of quantitative information within the shortest period of time, we have adopted a combined megascopic-microscopic procedure. Megascopic analysis is used to identify the distinctive lithologies present, and microscopic analysis is required only to describe representative examples of the mixed lithologies observed. This procedure greatly decreases the number of microscopic analyses needed for adequate description of a sample. For quantitative megascopic description of coal microlithotypes, microlithotype assemblages, and lithotypes, we use (V) for vitrite or vitrain, (E) for liptite, (I) for inertite or fusain, (M) for mineral layers or lenses other than iron sulfide, (S) for iron sulfide, and (X1), (X2), etc. for mixed lithologies. Microscopic description is expressed in terms of V representing the vitrinite maceral group, E the exinite group, I the inertinite group, and M mineral components. volume percentages are expressed as subscripts. Thus (V)20(V80E10I5M5)80 indicates a lithotype or assemblage of microlithotypes consisting of 20 vol. % vitrite and 80% of a mixed lithology having a modal maceral composition V80E10I5M5. This bulk composition can alternatively be recalculated and described as V84E8I4M4. To generate these quantitative data rapidly and accurately, we utilize an automated image analysis system (AIAS). Plots of VEIM data on easily constructed ternary diagrams provide readily comprehended illustrations of the range of modal composition of the lithologic units making up a given coal

    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 educational survey demonstrated significantly higher scores in the animation group. A prospective, randomized, blinded study comparing the educational efficacy of a surgical textbook to digital animation demonstrates that, in novice learners, digital animation is a more effective tool for learning the Ivy loop technique. Test takers found digital animation to be the superior educational medium.

    Full Text Available This research was aimed at identifying the approaches, methods and techniques used by the English teachers at a state senior high school in Enrekang, Indonesia in teaching English as a foreign language. Furthermore, the consistency of the approaches, methods, and techniques is also identifed. This research applied explorative qualitative research design. The subjects were all of the English teachers in that school. They were chosen through purpossive sampling technique. They were interviewed and observed to get data regarding their teaching approach, method, and technique. Their lesson plan were copied to gain supporting data. Based on fndings and discussion, the approaches used by teacher 1 were communicative and behaviorism approach. Teacher 2 applied systemic functional linguistic and constructivism/ cognitivism. Most of the techniques used by teacher 1 reflected behaviorism approach or principles of grammar translation method while the techniques used by teacher 2 reflected both of behaviorism and constructivism. In the case of the consistency, the English teachers still showed a considerable inconsistency. Yet, comparing with teacher 1, teacher 2 was more consistent. It is concluded that the two English teachers still need further upgrading regarding approaches, methods, and techniques of teaching English as a foreign language.

    Many of the cognitive behavioral models and therapeutic protocols developed so far for psychological disorders and chronic diseases have proved effective through clinical research. This study aimed to determine the effectiveness of teaching cognitive-behavioral techniques on locus of control in hemodialysis patients. This controlled clinical trial study was conducted in 2015 with 76 patients selected by census and treated with a hemodialysis machine in the dialysis department of Vali-Asr Hospital in the city of Meshkinshahr. A total of four patients were excluded because of their critical conditions while the rest, who were recruited, were randomly divided into two equal groups of 36 patients as the intervention and control groups. First, the locus of control was measured in both groups through a pretest, and cognitive-behavioral techniques were then taught to the intervention group during eight 45 to 90-minute sessions. The locus of control in patients of both groups was finally re-measured through a posttest. Data were collected using Rotter's Locus of Control Inventory. The Wilcoxon test and Mann-Whitney U test were respectively used in SPSS18 for data analysis. In the pretest and posttest stages respectively, 4.8% and 14.3% of samples in the control group as well as 14.3% and 33.3% of samples in the intervention group enjoyed internal locus of control. The difference between the pretest and posttest scores of internal locus of control in the intervention group was significant (p=0.004), which indicates the positive effect of cognitive-behavioral psychotherapeutic intervention on internalization of locus of control in this group. Given the external locus of control in most of the study patients and also the positive significant effect of cognitive-behavioral psychotherapy on internalization of locus of control in this group of patients, it appears necessary to have a psychology resident present in the hemodialysis department to teach the necessary cognitive

    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

    Courses are an important way of cultivating talents in college education. Advanced training schemes and the course system are implemented through course teaching. Advanced teaching notions and methods also rely on course teaching. Therefore, the quality of course teaching is the fundamental guarantor for grooming talent. The teachers of the course "Microcontroller Principles and Interface Techniques" in the Optical Science and Engineering College of Zhejiang University insist on course teaching becoming student centered and ability-training-oriented. They pay attention to students'all-round development in terms of learning ability, practical ability, innovation ability, and exploring spirit. They actively carried out course reforms in four aspects, namely teaching, learning, evaluation, and experimentation. This paper mainly introduced these reforms. First, the teaching method was reformed by introducing case analysis and the notion of a flipped classroom to shift the course focus from the teacher to the students. Second, the learning method was reformed through the use of techniques such as peer learning and project design to promote students' sense of enquiry and learning initiative. Third, the evaluation method was reformed through the use of process assessment and diversity evaluation to encourage students to develop logical thinking and a down-to-earth manner. Fourth, the experimentation method was reformed by introducing hierarchical content, process management, and diversification of examination to change students'learning attitude from "dependence, passivity, and imitation" to "independence, active involvement, and creation."In general, the teaching method reform promoted reforms in learning, evaluation, and experimentation methods and further improved the style of study. These reforms improved teachers' teaching abilities and enabled course teaching to transform from being teacher centered to student centered. Years of exploration and practice results have

    To compare mini-sling and traditional tension-free operations for female stress urinary incontinence. A systematic review of articles in the Literature published between 2002 and 2012, was conducted. A Pubmed search was performed. Primary outcomes were subjective and objective cure rates at 12 months comparing the three single-incision mini-slings techniques (TVT-Secur, MiniArc and Monarc systems) with the standard midurethral sling procedure TOT (Transobturator Vaginal Tape). Secondary outcomes included peri-operative (vaginal and/or bladder perforation, urine retention, urinary tract infection, bleeding, pain) and post-operative (mesh exposure, de novo urgency, and dyspareunia) complications. In term of objective cure rate at 12 month after surgery, it is evident that TOT at first, and MiniArc are the most effective procedures. The incidence of post-operative urgency and UTI was lower in TOT technique, while vaginal perforation was described in equal frequency both in TOT and in MiniArc procedures. The advantages of the three above described mini-invasive techniques seem to consist into lower cases of urinary retention, pain and bleeding. Furthermore, bladder perforation and bleeding are not described in the Literature for TVT-Secur and Monarc systems. Some single-incision slings look promising and as effective as conventional sub-urethral slings at short term evaluation. However, at this moment a clear statement in favor of the widespread use of single-incision slings cannot be made. More studies must define the efficacy of these techniques.

    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.

As part of EAU Urology Week 2010, 108 school children aged 15-19 attended a seminar with lectures and simulators (laparoscopy, TUR, cystoscopy, and suture sets) at the 62nd Congress of the German Society of Urology in Düsseldorf. A Pub-Med and Google Scholar search was also performed in order to review the beneficial effects of early virtual surgical training. MeSh terms used were "video games," "children," and "surgical skills." Searches were performed without restriction for a certain period of time. In terms of publicity for urology, EAU Urology Week, and the German Society of Urology, the event was immensely successful. Regarding the literature search, four relevant publications were found involving children. An additional three articles evaluated the usefulness of video gaming in medical students and residents. Making use of virtual reality to attract and educate a new generation of urologists is an important step in designing the future of urology.

    Schneider, Wolfgang

    2013-09-01

    The distal soft tissue procedure has evolved into an indispensable additional surgical procedure to increase the corrective effect in hallux valgus surgery. Considering the biomechanical development of hallux valgus deformity, degenerative changes of the soft tissues around the first metatarsophalangeal joint contribute much more to the deformity than changes in the bony structures which can rather be seen as degenerative changes secondary to the deformity. Thus the principles in hallux valgus correction should aim to reverse all pathogenetic steps leading to deformity: release of the contracted lateral soft tissue structures, tightening of the torn-out medial structures and reduction and rebalancing the first metatarsal head onto the sesamoid complex. The scientific discussion over the last decades has clarified the impact of different surgical steps and methods on the efficacy of the lateral release, the risk of creating overcorrection or instability of the joint and the risk of avascular necrosis of the first metatarsal head. According to anatomical and clinical data, a lateral soft tissue release can be combined with a distal metatarsal osteotomy, provided that the osteotomy is performed in a defined safe zone without increasing the risk for avascular necrosis of the first metatarsal head. Transecting the lateral metatarsosesamoid suspensory ligament is the key to a successful lateral release in hallux valgus surgery. Release of the deep transverse metatarsal ligament and the adductor hallucis muscle does not contribute to hallux valgus correction. The lateral short sesamophalangeal ligament and the plantar attachment of the articular capsule should be preserved to avoid possible joint instability. Thus today, the distal soft tissue procedure cannot be seen only as a supplementary surgical procedure in cases where the bony procedure needs additional correction, but rather is an indispensable procedure to restore the physiological situation and function of the

    A linear statistical technique using a 'leaps and bounds' procedure (Furnival and Wilson, 1974) is developed for retrieving geophysical parameters from remote measurements. It is used for retrieving sea surface temperatures from the Scaning Multichannel Microwave Radiometer (SMMR) on Seasat. The technique uses an efficient algorithm to select the best fixed-size subset of the 10 SMMR channels for linearly retrieving a given geophysical parameter. The 5-channel subset (6.6V, 6.6H 10H, 18V, 21H), where V and H refer to, respectively, the vertical and horizontal polarizations and the numbers are the channel frequencies in gigahertz, gives the minimum rms error in estimating the sea surface temperature. A comparison with ground truth indicates that the algorithm infers the temperature with an rms accuracy of better than 1.5 K under most environmental conditions. A quality control procedure which is seen as holding promise for further improving the accuracy is proposed.

  1. The Effectiveness of Distraction as Procedural Pain Management Technique in Pediatric Oncology Patients: A Meta-analysis and Systematic Review.

    2017-10-01

    Diagnostic tests and treatment regimens for pediatric cancers involve invasive and painful procedures. Effective management of such pain has been shown to be suboptimal in many parts of the world, often because of the cost and limited availability of appropriate medications. Current evidence suggests that distraction (a relatively low-cost technique) is a promising intervention for procedural pain management. There is, however, limited evidence demonstrating its effectiveness in pediatric oncology patients. A systematic review was conducted to ascertain the effectiveness of distraction as a procedural pain management technique in pediatric oncology patients. Using a comprehensive search strategy, MEDLINE, PsycINFO, Cochrane Library, AMED, CINAHL, Web of Science, and EMBASE electronic databases were searched for studies comparing distraction techniques to standard care/any intervention. Using the selected studies, a systematic review and meta-analysis of randomized controlled trials was conducted. Two hundred ninety-nine studies were identified, with seven randomized control trials identified as eligible for inclusion. Pain was assessed using self-report, observer-report, and physiological measures. A meta-analysis of four studies showed distraction as effective in reducing procedural pain, based on self-reported pain. A meta-analysis of three studies, based on pulse rates, demonstrated similar results. For observer-reported pain, limited evidence supported the effectiveness of distraction. This systematic review demonstrates that distraction is a promising intervention for procedural pain. Future research should assess effectiveness of distraction in varied populations, to explore evidence of cultural influences on pain expression, measurement, and management approaches.

    We performed three-dimensional numerical simulations of the solar surface acoustic wave field for the quiet Sun and for three models with different localized sound-speed perturbations in the interior with deep, shallow, and two-layer structures. We used the simulated data generated by two solar acoustics codes that employ the same standard solar model as a background model, but utilize different integration techniques and different models of stochastic wave excitation. Acoustic travel times were measured using a time-distance helioseismology technique, and compared with predictions from ray theory frequently used for helioseismic travel-time inversions. It is found that the measured travel-time shifts agree well with the helioseismic theory for sound-speed perturbations, and for the measurement procedure with and without phase-speed filtering of the oscillation signals. This testing verifies the whole measuring-filtering-inversion procedure for static sound-speed anomalies with small amplitude inside the Sun outside regions of strong magnetic field. It is shown that the phase-speed filtering, frequently used to extract specific wave packets and improve the signal-to-noise ratio, does not introduce significant systematic errors. Results of the sound-speed inversion procedure show good agreement with the perturbation models in all cases. Due to its smoothing nature, the inversion procedure may overestimate sound-speed variations in regions with sharp gradients of the sound-speed profile.

    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 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. PMID:23858288

    Nowak, Rafał; Trybek, Grzegorz

    Choosing an appropriate fixation technique after maxillary or mandibular osteotomy is one of the key factors affecting the success of orthognathic surgery. In line with the development of new surgical methods and techniques, the surgeons’ approach to the fixation of bone fragments has evolved accordingly, varying from non-fusion to different osteosynthesis techniques. Advances in medical sciences and medical technologies, have changed our attitudes to bone fragment reduction in orthopaedics and traumatology, and also in maxillofacial surgery. The pivotal underlying principle which determines bone healing – that is proper positioning so as to ensure appropriate contact area and immobilisation so as to ensure osteosynthesis – has remained unchanged for centuries. However, over the years, patient comfort and the predictability of treatment outcomes have vastly improved. The paper provides an overview of the techniques and methods used for the fixation of osteotomized fragments after bilateral sagittal split osteotomy since its introduction by Hugo Obwegeser up to the present day.

    2008-06-01

    Organ and effective dose to ninety (90) patients undergoing myelogram, urethrogram, barium swallow, barium meal and barium enema examinations at the KorIe-Bu Teaching Hospital was estimated using the Monte Carlo Code (PCXMC). Free in air measurements were made with a calibrated ionisation chamber to estimate the entrance surface air kerma for each examination. Evaluation of fluoroscopy beam on time and number of radiographs taken per patient was done for all the examinations considered and studies were done on how they affect patient dose. Dose area product (DAP) was calculated from the entrance surface air kerma and the area of the beam on the surface of the patient and compared with internationally accepted reference levels. Excess relative risk of site specific solid cancer and all solid cancers excluding thyroid and Non-melanoma skin cancers incidences were estimated for the various examinations using Biological Effects of Ionising Radiation VII Committee risk model from the knowledge of the mean effective doses for each examination. The mean effective dose was found to be 0.29 :±: 0.07 mSv for urethrogram, 0.84:±: 0.13 mSv for barium swallow, 3.15 :±: 0.44 mSv for barium meal, 6.24 :±: 0.7 mSv for barium enema and 0.38 :I: 0.05 mSv for myelogram examinations. The estimated mean dose area product (DAP) was found to be 3.55 :±: 0.95 Gycm2 for urethrogram, 16.44:1: 2.60 Gycm2 for barium swallow, 50.81 :±: 7.04 Gycm2 for barium meal, 99.69 :±: 10.85 Gycm2 for barium enema and 9.32 :±: 0.99 Gycm2 for myelogram examinations. The estimated excess relative risk for the occurrence of all solid cancer was found to be 9.5700E-S and 1.6530E-4 for males and females respectively undergoing urethrogram examination, 2.7720E-4 and 4.7880E-4 for males and females respectively undergoing barium swallow examination, 1.0395E-3 and 1.7955E-3 for males and females respectively undergoing barium meal examination, 2.0592E-3 and 3.5568E-3 for males and females respectively

    2017-07-01

    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

    Minimally invasive approaches to gynecologic surgery have quickly gained favor. The da Vinci surgical system robot as an option for minimally invasive surgery offers many advantages. As the placement of the system between the legs can be prohibitive, we propose a modification of the standard docking procedure by aligning the system parallel to the operating room table. Our experience is that parallel side-docking allows access to the perineum without compromising docking time and range of motion.

    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.

    Full Text Available We describe a novel technique to exchange an Impella over a guide-wire, preserving the arteriotomy access and to lower the risks of vascular complications. We describe this technique in the context of two interesting cases. The first case is of a young man with myocarditis and cardiogenic shock from a previously undiagnosed systemic lupus erythematous. The second case is of a woman with ST elevation myocardial infarction and cardiogenic shock requiring complex percutaneous intervention. The implantation of Impella CP served as circulatory support in these cases as myocardium recovered but was complicated by access site bleeding. We were able to remove the Impella device while maintaining the access sheath to allow for adequate hemostasis prior to sheath removal. We believe the readers of the journal will find these images and technique interesting and useful in their own practice.

    Simulation technologies are gaining widespread acceptance across a variety of educational domains and applications. The current research examines whether basic nursing procedure training with high-fidelity versus low-fidelity mannequins results in differential skill acquisition and perceptions of simulator utility. Fifty-two first-year students were taught nasogastric tube and indwelling urinary catheter insertion in one of two ways. The first group learned nasogastric tube and urinary catheter insertion using high-fidelity and low-fidelity mannequins, respectively, and the second group learned nasogastric tube and urinary catheter insertion using low-fidelity and high-fidelity mannequins, respectively. The dependent measures included student performance on nasogastric tube and urinary catheter insertion testing, as measured by observer-based instruments, and self-report questionnaires probing student attitudes about the use of simulation in nursing education. Results demonstrated higher performance with high-fidelity than with low-fidelity mannequin training. In response to a self-report posttraining questionnaire, participants expressed a more positive attitude toward the high-fidelity mannequin, especially regarding its responsiveness and realism.

    This paper describes an alternative methodology to determine the thermal effusivity of a liquid sample using the recently proposed electropyroelectric technique, without fitting the experimental data with a theoretical model and without having to know the pyroelectric sensor related parameters, as in most previous reported approaches. The method is not absolute, because a reference liquid with known thermal properties is needed. Experiments have been performed that demonstrate the high reliability and accuracy of the method with measurement uncertainties smaller than 3%.

    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.

In this work a response surface is applied to the design optimization of a helicopter rotor blade. In previous work, this problem has been formulated with a multilevel approach. Here, the response surface takes advantage of this decomposition and is used to replace the lower level, a structural optimization of the blade. Problems that were encountered and important considerations in applying the response surface are discussed. Preliminary results are also presented that illustrate the benefits of using the response surface.

    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...

    UCN 5 and 6 nuclear units (OPR-1000) are being constructed and the Korean Next Generation Reactor (APR-1400) is being designed by using digital I and C equipment for the safety functions such as a reactor protection system, an engineered safety feature actuation system, and a safety equipment control system. Even though the use of digital equipment for safety-related functions provides many advantageous features, there are still many arguable safety issues remaining. Design, configuration management and maintenance are important application areas for the probabilistic safety assessment (PSA). Digital I and C systems are natural candidates for PSA applications. From the viewpoint of the PSA, the digital techniques are very different from the conventional techniques of analog I and C systems because of some unique features. This article aims at giving an overview for the important issues of digital system PSA and at presenting the current status of technology development for each issue. Korea Atomic Energy Research Institute (KAERI) has performed an initiative research in order to meet risk information needs for digitalized safety-critical systems in Korea. The technologies presented in this article especially focusing on those developed in the KAERI

    Full Text Available Introduction: Ineffective communication is a main factor in engender of unwanted hospital errors and impede suitable patient care. SBAR technique (Situation-Background- Assessment- Recommendation is a standard tool for building communication among healthcare professionals. While educating the SBAR technique requires appropriate educational methods, but this issue has been less investigated. So, the aim of present study was to compare the effect of educating the SBAR technique with role play and lecturing on communication skills of nurses in transferring patients to next shift. Methods: This quasi-experimental study conducted by participating 78 nurses who assigned to role play and lecturing groups randomly. SBAR technique was educated to each group separately. At the end of the learning session in each group, the skills of the participants in performing SBAR technique were investigated by the standard SBAR scale. Data analysis was performed by using SPSS statistical software version 11.5. Results: Comparison the total score of performing SBAR technique using independent samples t-test showed statistical differences between mean score of role play and lecturing groups. Similarly, comparison the scores of skill in performing each four parts of SBAR technique showed statistical differences between two groups.Conclusion: Role play is an effective educational method in teaching SBAR technique for nurses and it can be used as a tool for build effective communication between healthcare professionals.

    Full Text Available Background: About half of all patients who undergo mitral valve surgery suffer from atrial fibrillation (AF. Cox described the surgical cut-and-sew Maze procedure, which is an effective surgical method but has some complications. This study was designed to evaluate the efficacy of a substitution method of radiofrequency ablation (RFA for patients undergoing mitral valve surgery with AF.Methods: We evaluated 50 patients, comprising 40 men and 10 women at a mean age of 61.8 ± 7.5 years, who underwent mitral valve surgery with RFA between March 2010 and August 2013. All the patients had permanent AF with an enlarged left atrium (LA. The first indication for surgery was underlying organic lesions. Mitral valve replacement or repair was performed in the patients as a single procedure or in combination with aortic valve replacement or coronary artery bypass grafting. Radiofrequency energy was used to create continuous endocardial lesions mimicking most incisions and sutures. We evaluated the pre- and postoperative LA size, duration of aortic cross-clamping, cardiopulmonary bypass time, intensive care unit stay, and total hospital stay.Results: The mean preoperative and postoperative LA sizes were 7.5 ± 1.4 cm and 4.3 ± 0.7 cm (p value = 0.0001, respectively. The mean cardiopulmonary bypass time and the aortic cross-clamping time were 134.3 ± 33.7 minand 109.0 ± 28.4 min, respectively. The average stay at the intensive care unit was 2.1 ± 1.2 days, and the total hospital stay was 8.3 ± 2.4 days. Rebleeding was the only complication, found in one patient. There was no early or late mortality. Eighty-two percent of the patients were discharged in normal sinus rhythm. Five other patients had normal sinus rhythm at 6months' follow-up, and the remaining 4 patients did not have a normal sinus rhythm after 6 months.Conclusion: Radiofrequency ablation, combined with LA reduction, is an effective option for the treatment of permanent AF concomitant with

    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.

    Fluoroscopy is widely used in spine surgery to assist with graft and hardware placement. Previous studies have not measured radiation exposure to a surgeon during minimally invasive lateral lumbar spine surgery for single-level discectomy and interbody cage insertion. This study was performed to model and measure radiation exposure to a surgeon during spine surgery using the direct lateral lumbar procedure. The study was performed using a mannequin substituting for the surgeon and a cadaver substituting for the patient. Radiation was measured with dosimeters attached to 6 locations on the mannequin using a OEC Medical Systems 9800 C-arm fluoroscope (OEC Medical Systems, Salt Lake City, Utah). Three different fluoroscopy setups were tested: a standard imaging setup, a standard setup using pulsed-mode fluoroscopy, and a reversed setup. The experiment was tested 5 times per setup, and the dosimeters' values were recorded. The highest amount of radiation exposure occurred when obtaining an anteroposterior view of the spine in the standard setup. Compared with the standard setup, the pulsed-mode setting decreased the radiation exposure to the mannequin by a factor of 6 times (P exposure to the mannequin by a factor of 6 times (P exposure to the eye level (P exposure. Radiation exposure to the surgeon can be greatly minimized by using either a pulsed imaging mode or the reversed setup. The reversed setup has the lowest amount of radiation exposure to the eye level.

    Neutrons have a unique role to play in determining the structure and dynamics of proteins and their complexes. Water molecules surrounding a protein play important roles in maintaining its structural stability. However, the hydration structures of most proteins are not known well at an atomic level because x-ray protein crystallography has difficulties to localize the position of hydrogen atoms, while neutron crystallography has not problem in determining the position of hydrogen atoms with high accuracy. A software suite, called Crystallography and NMR System (CNS), has been developed for macromolecular structure determinations by x-ray crystallography or solution nuclear magnetic resonance spectroscopy by A.T. Brunger et al. The software CNS is highly flexible, and is applied for neutron diffraction measurements after some modifications of parameters used in the software. The fundamental modifications are the followings; D atoms in replace of H atoms, and the substitution of neutron scattering lengths for x-ray scattering factors. Moreover, in neutron diffraction data analysis, an important problem rests on the introduction of hydrogen atoms into the software of x-ray crystallography without hydrogen atoms. After the above procedures, the software modified is applied to determine the molecular structure of histidine residue associated with hydrogen atoms. (author)

    This paper discusses nitrogen determination with the Cameca SX50 electron microprobe using PCO as an analyzing crystal. A set of conditions using differing accelerating voltages, beam currents, beam sizes, and counting times were tested to determine parameters that would give the most reliable nitrogen determination. The results suggest that, for the instrumentation used, 10 kV, current 20 nA, and a counting time of 20 s provides the most reliable nitrogen determination, with a much lower detection limit than the typical concentration of this element in coal. The study demonstrates that the electron microprobe technique can be used to determine the nitrogen content of coal macerals successfully and accurately. ?? 2001 Elsevier Science B.V.

    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

  16. Treating the Initial Physical Reflex of Misophonia With the Neural Repatterning Technique: A Counterconditioning Procedure

    Directory of Open Access Journals (Sweden)

    Thomas H. Dozier

    2015-10-01

    Full Text Available Misophonia is a condition in which a person has an acute emotional response of anger or disgust to a commonly occurring innocuous auditory or visual stimulus referred to as a trigger. This case details the effective treatment of misophonia in a young woman that included a counterconditioning treatment called the Neural Repatterning Technique (NRT, which combines a continuous positive stimulus and a reduced intensity, intermittent trigger. The treatment was delivered via the Misophonia Trigger Tamer smartphone app and all treatments were conducted independently by the patient. In this patient, the trigger elicited a physical reflex of contraction of the flexor digitorum profundus, which caused her to clench her fist. To enhance the effect of the NRT treatment, Progressive Muscle Relaxation was incorporated to increase her ability to deliberately relax the affected muscle during treatment. During NRT treatment sessions, the patient experienced a weak physical reflex to the reduced trigger stimulus but no emotional response. Her emotional response of misophonia was not treated, but when the physical reflex extinguished, the emotional response also extinguished. This case indicates that the misophonic response includes a Pavlovian-conditioned physical reflex. It is proposed that the trigger elicited the physical reflex and the physical reflex then elicited the conditioned emotional response that is characteristic of misophonia. Because of the conditioned reflex nature of misophonia, it is proposed that a more appropriate name for this disorder would be Conditioned Aversive Reflex Disorder.

    Ding, George X; Munro, Peter

    2013-07-01

    To compare imaging doses from MV images, kV radiographs, and kV-CBCT and describe methods to reduce the dose to patient's organs using existing on-board imaging devices. Monte Carlo techniques were used to simulate kV X-ray sources. The kV image doses to a variety of patient anatomies were calculated by using the simulated realistic sources to deposit dose in patient CT images. For MV imaging, the doses for the same patients were calculated using a commercial treatment planning system. Portal imaging results in the largest dose to anatomic structures, followed by Varian OBI CBCT, Varian TrueBeam CBCT and then kV radiographs. The imaging doses for the 50% volume from the DVHs, D50, to the eyes for representative head images are 4.3-4.8cGy; 0.05-0.06cGy; 0.04-0.05cGy; and, 0.12cGy; D50 to the bladder for representative pelvis images are 3.3cGy; 1.6cGy; 1.0cGy; and, 0.07cGy; while D50 to the heart for representative thorax images are 3.5cGy; 0.42cGy; 0.2cGy; and, 0.07cGy; when using portal imaging, OBI kV-CBCT scans, TrueBeam kV-CBCT scans and kV radiographs, respectively. The orientation of the kV beam can affect organ dose. For example, D50 to the eyes can be reduced from 0.12cGy using AP and right lateral radiographs to 0.008-0.017cGy when using PA and right lateral radiographs. In addition, organ exposures can be further reduced to 15-70% of their original values with the use of a full-fan, bow-tie filter for kV radiographs. In contrast, organ doses increase by a factor of ∼2-4 if bow-tie filters are not used during kV-CBCT acquisitions. Current on-board kV imaging devices result in much lower imaging doses compared to MV imagers even taking into account of higher bone dose from kV X-rays. And a variety of approaches are available to significantly reduce the image doses. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    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 purposes of this research were (1 to develop English for communication skills for grades 1-6 teachers, 2 to develop the teachers’ English teaching skills, and (3 to increase the students’ English Achievement.  The participants were 15 teachers with no degree in English from 14 small size primary schools in Lop Buri province Thailand. The 30 hour English communication and 30 hour English teaching training were provided to the teachers. School visits with Coaching approach were applied for supporting their teaching at schools as well as teaching materials the teachers needed. A questionnaire comprising both open and closed-ended questions was used to evaluate the teachers’ teaching. The interview questions and the teachers’ reflection form were conducted for collecting their perception on the project, percentage and mean were applied to analyze quantitative data whereas content analysis was conducted for qualitative data. The findings showed that the teachers’ English for communication skills and English teaching skills were increased. The teachers’ English communication skills and their teaching skills were higher than before whereas their teaching application was at a medium level. Fifty percent of the teachers’ teaching skills were at a high level while 20% barely applied their teaching experience they received from the training and coaches. One hundred percent of the teachers agreed that the project was the most useful for them and many highlighted that they’d immensely learned teaching techniques and just realized that they could make their English class interesting for the students because they felt confident after the training. However, a few teachers had no chance to teach English because their schools had someone qualified to teach instead.

Material and Methods: Fifteen subjects, of age 8-10 years requiring local anesthesia on both sides of the dental arch for the purpose of extraction were selected for this study. In this cross-over design study, randomization was done to allocate the type of local anesthetic technique to be used first, children who received CCLAD (Wand during ′First Anesthetic Exposure′ (FAE visit subsequently received ′Conventional anesthetic technique′ during ′Second Anesthetic Exposure′ (SAE visit and vice versa. Behavior assessment using ′Frankel′s Behavior Rating Scale′ (FBRS and anxiety assessment using ′Faces Version of Modified Child′s Dental Anxiety Scale′ (MCDAS f were done prior to the anesthetic exposure. ′Wong Baker′s Facial Pain Scale′ (WBFPS was used to assess the child′s pain perception to each of the two techniques, immediately after the injection. Various physiological parameters like ′Heart Rate′(HR, ′Respiratory Rate′(RR, and ′Oxygen Saturation′ were measured during pre-operative phase, LA-phase, post LA-phase, Extraction phase and post Extraction phase, during FAE and SAE. Results: Paired t-test revealed a very highly significant (P = 0.001 difference between CCLAD (Wand and conventional during SAE. Non-significant difference was observed when physiological parameters were compared at various intervals between the two anesthetic techniques. Conclusion: CCLAD (Wand provides lesser pain perception as compared to conventional local anesthetic technique.

    2017-11-01

    Cognitive load theory, focusing on limits of the working memory, is relevant to medical education; however, factors associated with cognitive load during procedural skills training are not well characterized. The authors sought to determine how features of learners, patients/tasks, settings, and supervisors were associated with three types of cognitive load among learners performing a specific procedure, colonoscopy, to identify implications for procedural teaching. Data were collected through an electronically administered survey sent to 1,061 U.S. gastroenterology fellows during the 2014-2015 academic year; 477 (45.0%) participated. Participants completed the survey immediately following a colonoscopy. Using multivariable linear regression analyses, the authors identified sets of features associated with intrinsic, extraneous, and germane loads. Features associated with intrinsic load included learners (prior experience and year in training negatively associated, fatigue positively associated) and patient/tasks (procedural complexity positively associated, better patient tolerance negatively associated). Features associated with extraneous load included learners (fatigue positively associated), setting (queue order positively associated), and supervisors (supervisor engagement and confidence negatively associated). Only one feature, supervisor engagement, was (positively) associated with germane load. These data support practical recommendations for teaching procedural skills through the lens of cognitive load theory. To optimize intrinsic load, level of experience and competence of learners should be balanced with procedural complexity; part-task approaches and scaffolding may be beneficial. To reduce extraneous load, teachers should remain engaged, and factors within the procedural setting that may interfere with learning should be minimized. To optimize germane load, teachers should remain engaged.

    Background. Pediatric medical information provision literature focuses on hospitalization and surgical procedures, but children would also benefit from an educational program regarding more commonly experienced medical procedures (e.g., needles, general check-up). Objective. To determine whether an evidence-based educational program reduced children's ratings of fear of and expected pain from medical stimuli and increased their knowledge of procedural coping strategies. Methods. An educational, interactive, developmentally appropriate Teddy Bear Clinic Tour was developed and delivered at a veterinary clinic. During this tour, 71 5-10-year-old children (Mage = 6.62 years, SD = 1.19) were taught about medical equipment, procedures, and coping strategies through modelling and rehearsal. In a single-group, pretest posttest design, participants reported their fear of and expected pain from medical and nonmedical stimuli. Children were also asked to report strategies they would use to cope with procedural fear. Results. Children's ratings for expected pain during a needle procedure were reduced following the intervention. No significant change occurred in children's fear of needles. Children reported more intervention-taught coping strategies at Time 2. Conclusions. The results of this study suggest that an evidence-based, interactive educational program can reduce young children's expectations of needle pain and may help teach them procedural coping strategies.

  10. A Finite Element Procedure with Poisson Iteration Method Adopting Pattern Approach Technique for Near-Incompressible Rubber Problems

    2014-08-01

    Full Text Available A finite element procedure is presented for the analysis of rubber-like hyperelastic materials. The volumetric incompressibility condition of rubber deformation is included in the formulation using the penalty method, while the principle of virtual work is used to derive a nonlinear finite element equation for the large displacement problem that is presented in a total-Lagrangian description. The behavior of rubber deformation is represented by hyperelastic constitutive relations based on a generalized Mooney-Rivlin model. The proposed finite element procedure using analytic differentiation exhibited results that matched very well with those from the well-known commercial packages NISA II and ABAQUS. Furthermore, the convergence of equilibrium iteration is quite slow or frequently fails in the case of near-incompressible rubber. To prevent such phenomenon even for the case that Poisson's ratio is very close to 0.5, Poisson's ratio of 0.49000 is used, first, to get an approximate solution without any difficulty; then the applied load is maintained and Poisson's ratio is increased to 0.49999 following a proposed pattern and adopting a technique of relaxation by monitoring the convergence rate. For a given Poisson ratio near 0.5, with this approach, we could reduce the number of substeps considerably.

    Full Text Available Abstract Background 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. Methods 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. Results 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. Conclusions 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.

    2016-04-01

    Anatomy is an essential component of medical education as it is critical for the accurate diagnosis in organs and human systems. The mental representation of the shape and organization of different anatomical structures is a crucial step in the learning process. The purpose of this pilot study is to demonstrate the feasibility and benefits of developing innovative teaching modules for anatomy education of first-year medical students based on three-dimensional (3D) reconstructions from actual patient data. A total of 196 models of anatomical structures from 16 anonymized computed tomography datasets were generated using the 3D Slicer open-source software platform. The models focused on three anatomical areas: the mediastinum, the upper abdomen, and the pelvis. Online optional quizzes were offered to first-year medical students to assess their comprehension in the areas of interest. Specific tasks were designed for students to complete using the 3D models. Scores of the quizzes confirmed a lack of understanding of 3D spatial relationships of anatomical structures despite standard instruction including dissection. Written task material and qualitative review by students suggested that interaction with 3D models led to a better understanding of the shape and spatial relationships among structures, and helped illustrate anatomical variations from one body to another. The study demonstrates the feasibility of one possible approach to the generation of 3D models of the anatomy from actual patient data. The educational materials developed have the potential to supplement the teaching of complex anatomical regions and help demonstrate the anatomical variation among patients.

    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.

    Gormally, Cara; Sullivan, Carol Subiño; Szeinbaum, Nadia

    2016-01-01

    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

    Video education has many advantages over traditional education including efficiency, convenience, and individualized learning. Learning sterile surgical technique (SST) is imperative for medical students, because proper technique helps prevent surgical site infections (SSIs). We hypothesize that video education is at least as effective as traditional skill demonstration in teaching first-year medical students SST. A video series was created to demonstrate SST ( https://www.youtube.com/playlist?list=PLcRU-gvOmxE2mwMWkowouBkxGXkLZ8Uis ). A randomized controlled trial was designed to assess which education method best teaches SST: video education or skill demonstration. First-year medical students (n = 129) were consented and randomly assigned into two groups: those who attended a skill demonstration (control group; n = 70) and those who watched the video series (experimental group; n = 59). The control group attended a pre-existing 90-minute nurse educator-led skill demonstration. Participants then completed a 30-item multiple choice quiz to test their knowledge. Each group then received the alternate education method and completed a 23-item follow-up survey to determine their preferred method. Seven 2- to 6-minute videos (30 minutes total) were created on surgical attire, scrubbing, gowning and gloving, and maintaining sterility. The experimental group (n = 51) scored higher on the quiz compared with the control group (n = 63) (88% ± 1% versus 72% ± 1%; p < 0.0001). Students preferred the videos when it came to convenience, accessibility, efficiency, and review, and preferred the skill demonstration when it came to knowledge retention, preparedness, and ease of completion. Video education is superior to traditional skill demonstration in providing medical students with knowledge of SST. Students identified strengths to each method of teaching. Video education can augment medical students' knowledge prior to their operating room

    This study examined the directive and non-directive supervisors' instructional styles, supervisees' interactive communications within supervision sessions as well as the relative success of supervisees' learning to apply specific techniques within psychotherapy. The developers of Time-Limited Dynamic Psychotherapy (TLDP) provided the supervised training for 16 therapists as part of the "Vanderbilt II" psychotherapy project. Supervision sessions were rated for supervisors' adherence to TLDP content. Both supervisors and supervisee were rated for classroom interactive behaviors of "initiation" speech (e.g., introducing ideas) and "responsive" speech (e.g., amplifying the other speaker's topic). The third therapy session was targeted for discussion within supervision. Therapy sessions immediately before and after supervision were rated on TLDP adherence. One of the supervisors (Supervisor A) was found to use an instructional style of relatively more initiation-based speech, whereas the other (Supervisor B) used more response-based speech. Technical adherence for supervisees of Supervisor A was significantly higher than those assigned to Supervisor B. Supervisees' initiation-based speech during supervision predicted less use of TLDP techniques in the therapy session after supervision. Supervisors' interactive style was not associated with therapy adherence. Relatively more directive and structured supervision may influence the acquisition and use of manual-prescribed therapy techniques.

    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.

    We report on efforts to design the "Collaborative Workshop Physics" (CWP) instructional strategy to deliver the first interactive engagement (IE) physics course at Khalifa University of Science, Technology and Research (KU), United Arab Emirates (UAE). To our knowledge, this work reports the first calculus-based, introductory mechanics course on the Arabian Peninsula using physics education research (PER)-based instruction. A brief history and present context of general university and STEM teaching in the UAE is given. We present this secondary implementation (SI) as a case study of a novel context and use it to determine if PER-based instruction can be successfully implemented far from the cultural context of the primary developer and, if so, how might such SIs differ from SIs within the United States (U.S.) in terms of criteria for and risks to their success. With these questions in view, a prereform baseline comprised of Maryland Physics Expectations in Physics survey, Force Concept Inventory (FCI), course exam grades, and English language proficiency data are used to design a hybrid implementation of Cooperative Group Problem Solving. We find that for students with high English proficiency, normalized gain on FCI improves substantially, from ⟨g⟩=0.16±0.10 prereform to ⟨g⟩=0.47±0.08 in the CWP pilot (standard errors), indicating a successful SI. However, we also find evidence that normalized gains on FCI are strongly modulated by language proficiency and discuss likely causes. Regardless of language ability, problem-solving skill is also substantially improved and course drop-fail-withdrawal rates are cut from 50% to 24%. In particular, we find evidence in postreform student interviews that prior classroom experiences, and not broader cultural expectations about education, are the more significant cause of expectations that are at odds with the classroom norms of well-functioning PER-based instruction. We present this result as evidence that PER

    Bench model hands-on learning may be more effective than traditional didactic practice in some surgical fields. However, this has not been reported for microsurgery. Our study objective was to demonstrate the efficacy of bench model hands-on learning in acquiring microsuturing skills. The secondary objective was to evaluate the aptitude for microsurgery based on personality assessment. Eighty-six medical students comprising 62 men and 24 women were randomly assigned to either 20 min of hands-on learning with a bench model simulator or 20 min of video-learning using an instructional video. They then practiced microsuturing for 40 min. Each student then made three knots, and the time to complete the task was recorded. The final products were scored by two independent graders in a blind fashion. All participants then took a personality test, and their microsuture test scores and the time to complete the task were compared. The time to complete the task was significantly shorter in the simulator group than in the video-learning group. The final product scores tended to be higher with simulator-learning than with video-learning, but the difference was not significant. Students with high "extraversion" scores on the personality inventory took a shorter time to complete the suturing test. Simulator-learning was more effective for microsurgery training than video instruction, especially in understanding the procedure. There was a weak association between personality traits and microsurgery skill.

    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.

    Clerkships are still the main source for undergraduate medical students to acquire necessary skills. However, these educational experiences may not be sufficient, as there are significant deficiencies in the clinical experience and practical expertise of medical students. An innovative course teaching basic clinical and procedural skills to first-year medical students has been implemented at the Medical University of Graz, aiming at preparing students for clerkships and clinical electives. The course is based on several didactic elements: standardized and clinically relevant contents, dual (theoretical and virtual) pre-course preparation, student peer-teaching, small teaching groups, hands-on training, and the use of medical simulation. This is the first course of its kind at a medical school in Austria, and its conceptual design as well as the implementation process into the curriculum shall be described. Between November 2011 and January 2013, 418 students have successfully completed the course. Four online surveys among participating students have been performed, with 132 returned questionnaires. Students' satisfaction with all four practical course parts was high, as well as the assessment of clinical relevance of contents. Most students (88.6%) strongly agreed/agreed that they had learned a lot throughout the course. Two thirds of the students were motivated by the course to train the acquired skills regularly at our skills laboratory. Narrative feedbacks revealed elements contributing most to course success. First-year medical students highly appreciate practical skills training. Hands-on practice, peer-teaching, clinically relevant contents, and the use of medical simulation are valued most.

  6. Analysis of a SNP linked to lactase persistence: An exercise for teaching molecular biology techniques to undergraduates.

    Schultheis, Patrick J; Bowling, Bethany V

    2011-01-01

    Recent experimental evidence indicates that the ability of adults to tolerate milk, cheese, and other lactose-containing dairy products is an autosomal dominant trait that co-evolved with dairy farming in Central Europe about 7,500 years ago. Among persons of European descent, this trait is strongly associated with a C to T substitution at a polymorphic site 13,910 bp upstream of the lactase gene. This mutation results in the persistent expression of lactase into adulthood enabling individuals carrying a T(-13,910) allele to digest lactose as adults. In this report, we describe a laboratory exercise for an undergraduate molecular biology course in which students determine their own genotype at the -13,910 polymorphic site and correlate this with their ability to tolerate dairy products. The exercise is used as a tool to teach basic molecular biology procedures such as agarose gel electrophoresis, PCR1, and DNA sequencing. Students are actively engaged in the learning process, not only by analyzing their own DNA but also by applying their knowledge and skills to answer an authentic question. The exercise is also integrated with lecture material on the control of gene expression at the transcriptional level, in particular, how transcription factors can influence the activity of a promoter by binding to cis-acting DNA regulatory elements located within the proximal promoter of a gene or distant enhancer regions.

    Despite emerging evidence to support the use of high velocity thrust manipulation in the management of lumbar spinal conditions, utilization of thrust manipulation among clinicians remains relatively low. One reason for the underutilization of these procedures may be related to disparity in training in the performance of these techniques at the professional and post professional levels. To assess the effect of using a new model of active learning on participant confidence in the performance of spinal thrust manipulation and the implications for its use in the professional and post-professional training of physical therapists. A cohort of 15 DPT students in their final semester of entry-level professional training participated in an active training session emphasizing a sequential partial task practice (SPTP) strategy in which participants engaged in partial task practice over several repetitions with different partners. Participants' level of confidence in the performance of these techniques was determined through comparison of pre- and post-training session surveys and a post-session open-ended interview. The increase in scores across all items of the individual pre- and post-session surveys suggests that this model was effective in changing overall participant perception regarding the effectiveness and safety of these techniques and in increasing student confidence in their performance. Interviews revealed that participants greatly preferred the SPTP strategy, which enhanced their confidence in technique performance. Results indicate that this new model of psychomotor training may be effective at improving confidence in the performance of spinal thrust manipulation and, subsequently, may be useful for encouraging the future use of these techniques in the care of individuals with impairments of the spine. Inasmuch, this method of instruction may be useful for training of physical therapists at both the professional and post-professional levels.

  12. 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.

    2016-05-01

    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

    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. Copyright © 2013 Elsevier Ltd.

    To develop and assess the validity of an evaluation tool to quantitatively assess the capsulorhexis portion of cataract surgery performed by residents. University of California at Los Angeles (UCLA), Department of Ophthalmology, Jules Stein Eye Institute, Los Angeles, California, USA. Masked prospective case series. Ophthalmology faculty members at UCLA were surveyed and literature was reviewed to develop a grading tool comprising 12 questions to evaluate surgical technique, including 4 from the Global Rating Assessment of Skills in Intraocular Surgery and 2 from the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric. Video clips of continuous curvilinear capsulorhexis (CCC) performed by 2 postgraduate year (PGY) 3 residents, 2 PGY 4 residents, and 2 advanced surgeons were independently graded in a masked fashion by a 7-member faculty panel. Four questions had low interobserver variability and a significant correlation with surgical skill level (intraclass correlation coefficient >0.75; Ptool. However, not all evaluation questions produced reliable results. The reliability and accuracy of the measurements appear to depend on the form and content of the question. Studies to optimize assessment tools identifying the best questions for evaluating each step of cataract surgery may help ophthalmic educators more precisely measure outcomes for improving teaching interventions.

    Full Text Available Responding to the call for reform in science education, changes were made in an introductory meteorology and climate course offered at a large public university. These changes were a part of a larger project aimed at deepening and extending a program of science content courses that model effective teaching strategies for prospective middle school science teachers. Therefore, revisions were made to address misconceptions about meteorological phenomena, foster deeper understanding of key concepts, encourage engagement with the text, and promote inquiry-based learning. Techniques introduced include: use of a flash cards, student reflection questionnaires, writing assignments, and interactive discussions on weather and forecast data using computer technology such as Integrated Data Viewer (IDV. The revision process is described in a case study format. Preliminary results (self-reflection by the instructor, surveys of student opinion, and measurements of student achievement, suggest student learning has been positively influenced. This study is supported by three grants: NSF grant No. 0202923, the Unidata Equipment Award, and the Lucia Harrison Endowment Fund.

    Transitioning to competency-based surgical training will require consensus regarding the scope of plastic surgery and expectations of operative ability for graduating residents. Identifying surgical procedures experts deemed most important in preparing graduates for independent practice (i.e., "core" procedures), and those that are less important or deemed more appropriate for fellowship training (i.e., "noncore" procedures), will focus instructional and assessment efforts. Canadian plastic surgery program directors, the Canadian Society of Plastic Surgeons Executive Committee, and peer-nominated experts participated in an online, multiround, modified Delphi consensus exercise. Over three rounds, panelists were asked to sort 288 procedural competencies into five predetermined categories within core and noncore procedures, reflecting increasing expectations of ability. Eighty percent agreement was chosen to indicate consensus. Two hundred eighty-eight procedures spanning 13 domains were identified. Invitations were sent to 49 experts; 37 responded (75.5 percent), and 31 participated (83.8 percent of respondents). Procedures reaching 80 percent consensus increased from 101 (35 percent) during round 1, to 159 (55 percent) in round 2, and to 199 (69 percent) in round 3. The domain "burns" had the highest rate of agreement, whereas "lower extremity" had the lowest agreement. Final consensus categories included 154 core, essential; 23 core, nonessential; three noncore, experience; and 19 noncore, fellowship. This study provides clarity regarding which procedures plastic surgery experts deem most important for preparing graduates for independent practice. The list represents a snapshot of expert opinion regarding the current training environment. As our specialty grows and changes, this information will need to be periodically revisited.

    In service inspection (ISI) of aged power plant parts has a delicate task to provide information on presence, position, orientation and size of defects in material. As far as results of ISI are just a starting point for elaborate procedure of structural integrity assessment, the accuracy and reliability of these results are particularly important. Time of Flight Diffraction (TOFD) technique is regarded as superior ultrasonic technique capable to fulfil required goals. In Slovenia TOFD is approved in nowadays routine inspection of components of conventional power plants. As there were no practical use of TOFD in Slovenian NPP yet, some experience from Slovenian conventional thermal power plants are presented. Results of TOFD inspections of turbine rotor and turbine inlet casing are shown. Simplified integrity assessment procedure (Nuclear Electric R6 procedure) can satisfy needs for assessing integrity of components in conventional PP, instead of detailed 3-D finite element simulation. Example of application of R6 procedure in conventional PP is shown in this paper . Although R6 results are relatively conservative, this relatively simple to use procedure could meet requirements for assessing safety margins in domestic Nuclear power plant too. (author)

    1985-01-01

    The illustrated case reports in this teaching atlas cover practically the entire range of possible pathological changes and are based on in-patient case material and 80,000 screening documents. The two basic approaches, - detection and analysis of changes -, are taught comprehensively and in great detail. A systematic procedure for analysing the mammographies, in order to detect even the very least changes, and its practical application is explained using mammographies showing unclear findings at first sight. A system of coordinates is presented which allows precise localisation of the changes. Exercises for practising the technique of identifying the pathological changes round up the methodolical chapters. Additional imaging technical enhancements and detail enlargements are of great help in interpreting the findings. The specific approach adopted for this teaching atlas is a 'reverse procedure', which leaves the beaten track and starts with analysing the mammographies and evaluating the radiographic findings, in order to finally derive the diagnosis.

    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.

    Dental anxiety and fear of needle injection is one of the most common problems encountered by dental practitioners, especially in the pediatric patient. In consequences, it might affect the patient's quality of life. Several methods are suggested to lower the discomfort of local anesthesia injection during dental procedures. Desensitization of injection site is one of the recommended strategies. Among chemical anesthetic topical agents that are effective but might have allergic side effects, using some nonpharmacological and safe techniques might be useful. This study aimed to overview the efficacy of using cooling techniques, mostly by ice or popsicles, warming or pH buffering of drug, and using modern devices to diminish the discomfort of local anesthesia injection during dental procedures.

    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 In this article, core pedagogic categories and its problematic elements such as: methods, forms, procedures, systems and laws are recreated. All this, as part of the pedagogical memory recovery through the discourse, in relation to this field of knowledge, that is done in the developments of José M. Zamora, as a reform that inspired the pedagogical practices during a period of the History of Education, the 20s, and especially inspired by the first German pedagogical mission.In the Manual of Pedagogy of Zamora, possibilities and visions from a hopeful World from the Education are seen. Some components arrive at the present time to be evaluated. The author distinguishes into three educational methods: physical, intellectual and moral; Pedagogical forms are classified into four: interrogative, expository, heuristics and narrative. The pedagogical procedures are divided in ten, whereas the educational systems in three: mutual or reciprocal, conferences and discussion. Finally, the pedagogical laws are divided in: physical, intellectual and moral. All of them are important elements in the contemporary pedagogical analysis.

    The use of pain control for disbudding and dehorning is important from both an animal and industry perspective. Best practices include the use of local anesthetic, commonly given as a cornual nerve block (CNB), and a nonsteroidal anti-inflammatory drug. The proportion is decreasing, but many dairy producers do not use local anesthesia, perhaps in part due to lack of knowledge of the CNB technique. Although this skill is typically learned in person from a veterinarian, alternative methods may be useful. The objective of this trial was to determine if there were differences in the efficacy of online training (n = 23), hands-on training (n = 20), and a combined approach (n = 23) for teaching producers to successfully administer a CNB and disbud a calf. The primary outcome was block efficacy, defined as a lack of established pain behaviors during iron application. Secondary outcomes were background knowledge (assessed by a written quiz), CNB and disbudding technique (evaluated by rubric scoring), time taken, and self-confidence before and after evaluation. Associations between training group and outcome were assessed with logistic regression, ordered logistic regression, and Cox-proportional hazard models, with a random effect for workshop. Block efficacy was not different between training groups, with 91% successful in both combined and online groups, and 75% in the hands-on trained group. Online learners had poorer technical scores than hands-on trainees. The combined group was not different from hands-on. Time to block completion tended to be longer for the online group (62 ± 11 s), whereas time to disbudding completion was not different between hands-on (41 ± 5 s) or combined trainees (41 ± 5 s). The combined group had the highest pre-evaluation confidence score, and remained higher after evaluation than online but was not different than hands-on. Although we saw some statistical differences between groups, absolute differences were small and block efficacy was

    To compare the failure rate (pregnancies) of a Pomeroy procedure and Filshie clips tubal occlusion at the time of Caesarean section. This is a retrospective observational study done in a district general hospital in the UK. There were 290 sterilisations performed at the time of Caesarean section over the period of 1994-2007. Studied population included 203 Pomeroy procedures and 87 Filshie clips applications. Follow-up period ranged from 2 to 15 years. A birth register and an operating theatre database were used to identify patients who underwent Caesarean section with a tubal occlusion. These patients' names were checked against the antenatal booking database, the early pregnancy assessment unit database, the operating theatre database in case of ectopic pregnancies, and a termination of pregnancy database to recognise failed sterilisation. There was no failure of tubal occlusion with a Pomeroy procedure (0/203). The failure rate of Filshie clips tubal occlusion was 1.15% (1/87) (p = 0.3). The length of the follow-up period ranged from 2 to 15 years (for Pomeroy procedure, median was 9 years and inter-quartile range (IQR) was 7; for Filshie clip, median was 8 years and IQR was 7). Pomeroy technique appears to carry a lower risk of a failed sterilisation than Filshie clips tubal occlusion at the time of Caesarean section. However, Pomeroy procedure needs to be balanced against the speed and simplicity of Filshie clips tubal occlusion.

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

    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

    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.

    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.

    Full Text Available This study mainly aims at applying Roundtable technique in teaching writing narrative text for the fourth semester students of English Education Department of IKIP PGRI Semarang in the academic year 2012-2013. This study also aims at finding out the problems faced by the students and the lecturer when the technique is applied in teaching learning process. The design of this study is a qualitative research. Observation and interview were used to collect the data. In analyzing the data, there are three steps done, namely data reduction, data display, and drawing conclusion. The result of the study is that to apply Roundtable technique in teaching narrative text, there are some steps done: 1 the students were grouped into six each of which consisted of 5 to 6 students, 2 the groups were given the same topic, 3 the lecturer gave a paper and a pen to each group, 4 roles were labeled to each student based on the generic structure of narrative text, 5 students in each group wrote narrative text based on the roles got, 6 each group submitted their work, 7 each group evaluated and corrected the other group’s work, and 8 each group reported their group evaluation to the whole class. There were some problems faced by the students when the technique applied: 1 the students seemed to face difficulty when they had to continue their friend’s work, and 2 the students tend to ask their friends in individual work because of their lack of vocabulary mastery, 3 chaos happened in some groups due to different perspective they had toward the story. Instead of the problems faced by the students, the lecturer also faced the difficulties in running this technique: 1 the lecturer got involved to deep in the group management and 2 the lecturer found it difficult in giving guidance to the students.

    ObjectiveTo 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.Materials and MethodsBetween 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.ResultsMean 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.ConclusionPercutaneous 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.

    PurposeThe purpose of our study is to evaluate results of percutaneous aspiration with alcohol sclerotherapy in symptomatic patients with simple hepatic cysts by employing single-session techniques either by a needle or a catheter.Materials and MethodsWe retrospectively included 39 simple hepatic cysts in 35 patients treated via percutaneous aspiration and single-session alcohol sclerotherapy between years 1993 and 2012. Indications were pain (n = 28) or ruling out cystic echinococcus (CE) disease (n = 7). 29 cysts in 26 patients were treated by needle technique (Group A) and ten cysts in nine patients were treated by single-session catheter technique (Group B). Patients were followed for 4–173 months (median: 38 months).ResultsAll patients were successfully treated. Before procedure, cyst volumes were 21–676 cc (median: 94 cc). Post-procedure cyst volumes at last follow-up were 0-40 cc (median: 1 cc). The mean decrease in cyst volume was 95.92 ± 2.86 % in all patients (95.96 ± 3.26 % in Group A and 95.80 ± 6.20 % in Group B). There was no statistically significant difference between the volume reduction rates of Group A and Group B. Only one patient, in Group B, developed a major complication, an abscess. Hospitalization period was 1 day for all patients.ConclusionsFor patients with symptomatic simple hepatic cysts smaller than 500 cc in volume by using puncture, aspiration, injection, and reaspiration (PAIR) technique with only needle, single-session alcohol sclerotherapy of 10 min is a safe and effective procedure with high success rate.

    Three-dimensional image fusion of preoperative computed tomography (CT) angiography with fluoroscopy using intraoperative noncontrast cone-beam CT (CBCT) has been shown to improve endovascular procedures by reducing procedure length, radiation dose, and contrast media volume. However, patients with a contraindication to CT angiography (renal insufficiency, iodinated contrast allergy) may not benefit from this image fusion technique. The primary objective of this study was to evaluate the feasibility of magnetic resonance angiography (MRA) and fluoroscopy image fusion using noncontrast CBCT as a guidance tool during complex endovascular aortic procedures, especially in patients with renal insufficiency. All endovascular aortic procedures done under MRA image fusion guidance at a single-center were retrospectively reviewed. The patients had moderate to severe renal insufficiency and underwent diagnostic contrast-enhanced magnetic resonance imaging after gadolinium or ferumoxytol injection. Relevant vascular landmarks electronically marked in MRA images were overlaid on real-time two-dimensional fluoroscopy for image guidance, after image fusion with noncontrast intraoperative CBCT. Technical success, time for image registration, procedure time, fluoroscopy time, number of digital subtraction angiography (DSA) acquisitions before stent deployment or vessel catheterization, and renal function before and after the procedure were recorded. The image fusion accuracy was qualitatively evaluated on a binary scale by three physicians after review of image data showing virtual landmarks from MRA on fluoroscopy. Between November 2012 and March 2016, 10 patients underwent endovascular procedures for aortoiliac aneurysmal disease or aortic dissection using MRA image fusion guidance. All procedures were technically successful. A paired t-test analysis showed no difference between preimaging and postoperative renal function (P = .6). The mean time required for MRA-CBCT image

    1993-09-01

    The oral health of the Swiss population was significantly improved by the successful prevention of dental caries and periodontitis. Along with the healthy dentition the demand for aesthetic dentistry is increasing. Removable partial dentures are becoming less accepted. Therefore, to substitute lost teeth by permanent fixed partial prosthesis (bridges), the often deformed alveolar ridge has to be operated, either to improve the aesthetic appearance or to make it possible to restore the missing teeth by a fixed cemented bridge. The aim of this paper is (1) to evaluate whether the moire technique is an appropriate and handy method, and (2) to validate the precision of the new method. The measuring system consisted of a moire projector with an integrated phase shift device and a moire viewer with a CCD video camera, connected to a frame grabber in a personal computer. a highly versatile software was allowed to control the system as well as to grab the moire images using the four-phase shift technique in order to compute the phase image of the actual object. The new technique was validated with one solid test object measured by a 3D coordination, high precision measuring machine.

    Nitrous oxide (N2 O 50% in oxygen) is commonly used for painful procedures in children. Potential negative health effects associated with chronic workplace exposure limit its use. Safe occupational N2 O exposure concentrations are below 25 ppm environmental concentration as a time-weighted average (TWA) and below 200 ppm as a short-time exposure level (STEL) of 15 min. The aim was to assess occupational exposure of staff during nitrous oxide administration to children using different inhalation delivery devices and scavenging systems. Staff nitrous oxide exposure during use of a double face mask (DFM) with or without a demand valve (DV) was compared with a conventional single face mask (FM). We also compared exposure using the hospital central scavenging system with a portable evacuation system. N2 O concentrations, representing exposure values, were monitored within proximity to staff. Urine N2 O concentration was measured in staff administering the N2 O at the end of the procedural session. The mean and median values of TWA and STEL within the working area were lower than recommended values in the DFM (10.8, 11.6 ppm for TWA; 13.9, 11.0 ppm for STEL) and DFM-DV groups (2.3, 2.8 ppm for TWA; 4.4, 3.5 ppm for STEL) using the portable evacuation system. The N2 O urine exposure in DFM-DV group was lower than DFM group: a mean difference of 9.56 ppm (95% CI 2.65-16.46). Staff N2 O urinary concentrations were within safe biological limits in both the DFM and DFM-DV groups. High exposure concentrations to N2 O were recorded in all FM and FM-DV environmental and biological samples. The DFM system, with or without a DV, connected to a portable evacuation system during N2 O administration to children for painful procedures kept N2 O levels within the local environment below recommended limits. © 2016 John Wiley & Sons Ltd.

    One of the factors that can affect the success of the Latarjet procedure is accurate coracoid graft (CG) placement. The use of a guide can improve placement of the CG and screw positioning in the sagittal and axial planes as compared with the classic open ("freehand") technique. Cohort study; Level of evidence, 2. A total of 49 patients who underwent a Latarjet procedure for the treatment of recurrent anterior shoulder instability were prospectively included; the procedure was performed with the freehand technique in 22 patients (group 1) and with use of a parallel drill guide during screw placement in 27 patients (group 2). All patients underwent a postoperative computed tomography scan with the same established protocol. The scans were used to evaluate and compare the position of the CG in the sagittal and axial planes, the direction of the screws (α angle), and overall contact of the graft with the anterior surface of the glenoid after the 2 surgical techniques. The CG was placed >60% below the native glenoid equator in 23 patients (85.2%) in group 2, compared with 14 patients (63.6%) in group 1 ( P = .004). In the axial plane, the position of the CG in group 2 patients was more accurate (85.2% and 88.9% flush) at the inferior and middle quartiles of the glenoid surface ( P = .012 and .009), respectively. Moreover, with the freehand technique (group 1), the graft was in a more lateral position in the inferior and middle quartiles ( P = .012 and .009, respectively). No differences were found between groups 1 and 2 regarding the mean α angle of the superior (9° ± 4.14° vs 11° ± 6.3°, P = .232) and inferior (9.5° ± 6° vs 10° ± 7.5°, P = .629) screws. However, the mean contact angle (angle between the posterior coracoid and the anterior glenoid surface) with the freehand technique (3.8° ± 6.8°) was better than that of the guide (8.55° ± 8°) ( P = .05). Compared with the classic freehand operative technique, the parallel drill guide can ensure

    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.

    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

    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.

    Ahmad Jabir Rahyussalim

    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.

    Because of continuous alveolar bone resorption, implant-retained overdentures need to be relined. The purpose of this study was to describe a method for relining an implant-retained overdenture. The authors present a step-by-step technique. A 65-year-old patient sought care for trauma and pain in the oral mucosa underneath his mandibular implant-retained overdenture. The overdenture had been fabricated 4 years previously. In addition, the patient mentioned the denture's lack of stability during function. On the basis of the patient's dental history, and clinical and radiographic examination results, the authors found alveolar bone resorption. In this case report, the authors describe the technique, analyze the procedure of implant-retained overdenture relining with a Locator attachment system (Locator abutment, H3, SP MB SZL03 for internal hex implants; MIS Seven), and describe how to restore the contact of the denture base with the denture-bearing tissues. The goal of this technique for the general dentist is to eliminate patients' tissue trauma and pain and increase the stability and support of the prosthesis.

    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

    Earth observation from space enables scientists and decision makers to forecast and react on the impacts of tropical storms. The project "Columbus Eye - Live-Imagery from the ISS in School Lessons" teaches pupils the implications of the coupled human-environment systems by applying remote sensing and digital image processing. Recently, Columbus Eye launched its first Android App featuring ISS videos. Generating a smartphone-based learning environment for working with ISS imagery introduces m-learning to the classrooms. The learning unit "The Eye of the Cyclone" addresses the formation and path of Philippine typhoon Maysak by using a multi-media approach. Based on a traditional work sheet, the diagrams of typhoon Maysak come alive when viewed through the smartphone's camera. A diagram of the typhoon's secret interior mechanics turns into a video of typhoon Maysak as seen from the ISS on 31st of March 2015, holding additional information on its unique specifications. The second diagram of air masses suddenly moves and shows the path of typhoon Maysak over time. But before those interactive parts are explored, the background information is presented in the work sheet by means of written scientific learning materials, including information on the occurrence, formation and inner structure of typhoons. Thus, fostering the reading competence, the pupils' understanding on the topic is assessed by several tasks on the work sheet's final page. The oral presentation explains how the haptic experience of writing the solutions on a sheet of paper makes the knowledge paperbound and "real", literally lifting pens & papers into space. In the light of the Copernicus services, it will be explained how Sentinel-based teaching units can be developed in order to communicating the knowledge and the handling of natural hazards in times of global change.

  12. More Learners, Finite Resources, and the Changing Landscape of Procedural Training at the Bedside.

    Gisondi, Michael A; Regan, Linda; Branzetti, Jeremy; Hopson, Laura R

    2017-11-21

    There is growing competition for non-operative, procedural training in teaching hospitals, due to an increased number of individuals seeking to learn procedures from a finite number of appropriate teaching cases. Procedural training is required by students, post-graduate learners, and practicing providers who must maintain their skills. These learner groups are growing in size as the number of medical schools increase and advance practice providers expand their skills to include complex procedures. These various learner needs occur against a background of advancing therapeutic techniques that improve patient care, but also act to reduce the overall numbers of procedures available to learners. This article is a brief review of these and other challenges that are arising for program directors, medical school leaders, and hospital administrators who must act to ensure that all of their providers acquire and maintain competency in a wide array of procedural skills. The authors conclude their review with several recommendations to better address procedural training in this new era of learner competition. These include a call for innovative clinical rotations deliberately designed to improve procedural training, access to training opportunities at new clinical sites acquired in health system expansions, targeted faculty development for those who teach procedures, reporting of competition for bedside procedures by trainees, more frequent review of resident procedure and case logs, and the creation of an institutional oversight committee for procedural training.

    Nowadays, small peripheral pulmonary lesions (PPLs) are frequently detected and the prognosis of lung cancer depends on the early diagnosis. Because of the high fee and requiring specialized training, many advanced techniques are not available in many developing countries and rural districts. Three sets of opaque soft copper wires visible under the fluoroscopy (Flu) in the Flu-flexible bronchoscopy (FB) group (n = 24), which determined the three planes of the lesion, were respectively placed firmly on the surface of the chest wall with adhesive tape on the chest wall. The FB tip was advanced into the bronchus toward the crosspoint of the three perpendicular planes under Flu with careful rotation of a C-arm unit. Then the specimen were harvested focusing around the crosspoint for pathologic diagnosis. The rapid on-site evaluation (ROSE) procedure was also performed. The average Flu time during FB procedures were recorded and diagnostic accuracy rates in the Flu-FB group were compared with the other group guided by radial endobronchial ultrasound (R-EBUS) (n = 23). The location of the core point of the lesion, whether it was visible or not under the fluoroscopy could be recognized by three-dimensional localization technique. The accuracy rates of diagnostic yields were 62.5% in the Flu-FB group, and was similar as 65.2% in the R-EBUS group (P > 0.05). However, in the Flu-FB group, there was a decreasing tendency on accurate diagnosis rates of lower lobe (LL) lesions when comparing with non-LL lesions (3/8 = 37.5% vs 12/16 = 75%, P = 0.091) while in the R-EBUS group it was similar (9/12 = 75% vs 6/11 = 54.6%, P = 0.278). In the Flu-FB group, fluoroscopy time was negatively correlated with the lesion length (r = -0.613, P = 0.001), however, there was no significant difference between the lesions invisible or not (5.83 ± 1.45 min vs 7.67 ± 2.02 min, P = 0.116) under the fluoroscopy, as well as no significant

    2013-05-01

    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.

    Damilakis, J; Stratakis, J; Solomou, G [University of Crete, Heraklion (Greece)

    2014-06-01

    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.

    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.

    A dual quasi-breath-hold (DQBH) technique is proposed for respiratory motion management (a hybrid technique combining breathing-guidance with breath-hold task in the middle). The aim of this study is to test a hypothesis that the DQBH biofeedback system improves both the capability of motion management and delivery efficiency. Fifteen healthy human subjects were recruited for two respiratory motion measurements (free breathing and DQBH biofeedback breathing for 15 min). In this study, the DQBH biofeedback system utilized the abdominal position obtained using an real-time position management (RPM) system (Varian Medical Systems, Palo Alto, USA) to audio-visually guide a human subject for 4 s breath-hold at EOI and 90% EOE (EOE90%) to improve delivery efficiency. We investigated the residual respiratory motion and the delivery efficiency (duty-cycle) of abdominal displacement within the gating window. The improvement of the abdominal motion reproducibility was evaluated in terms of cycle-to-cycle displacement variability, respiratory period and baseline drift. The DQBH biofeedback system improved the abdominal motion management capability compared to that with free breathing. With a phase based gating (mean ± std: 55  ±  5%), the averaged root mean square error (RMSE) of the abdominal displacement in the dual-gating windows decreased from 2.26 mm of free breathing to 1.16 mm of DQBH biofeedback (p-value = 0.007). The averaged RMSE of abdominal displacement over the entire respiratory cycles reduced from 2.23 mm of free breathing to 1.39 mm of DQBH biofeedback breathing in the dual-gating windows (p-value = 0.028). The averaged baseline drift dropped from 0.9 mm min-1 with free breathing to 0.09 mm min-1 with DQBH biofeedback (p-value = 0.048). The averaged duty-cycle with an 1 mm width of displacement bound increased from 15% of free breathing to 26% of DQBH biofeedback (p-value = 0.003). The study demonstrated that the DQBH biofeedback

    Full Text Available Many of the physical and functional properties of RDX and HMX explosives are related to the crystalline structure of these materials. Crystalline defects affect the quality of the explosives. Therefore, in order to enhance the quality of these materials, it is necessary to form crystals with the lowest defects. In this research, we report the optimization of recrystallization process of RDX and HMX by statistical techniques. The solvent/anti-solvent procedure was used for recrystallization of HMX and RDX particles. The four parameters of i ratio of anti-solvent to solvent, ii ratio of solute to solvent, iii aging time, and iv cooling rate of mixture, were optimized by Taguchi analysis design. Taguchi L16 orthogonal array was used with sixteen rows corresponding to the number of tests in four columns at four levels. The apparent density of recrystallized of RDX and HMX particles was considered as the quality characteristic with the concept of “the larger-the-better”. The obtained graphs showed that the studied parameters were optimized in ratio 1:1 for anti-solvent to solvent, ratio 0.1 g⋅mL-1 for solute to solvent, aging time of 2 h and cooling rate of 1 °C⋅min-1. Also, the correlation between the investigated parameters and apparent density of crystals were studied by multiple linear regressions (MLR method for obtaining a model of prediction of apparent density. The P-values were indicated that in confidence level of 95%, the null hypothesis is rejected and a meaningful addition is observed in the proposed model.

    The purpose of this study was to examine the influence of using the Cognitive Behaviour Modification (CBM) technique on the subtraction skills of third grade hearing and deaf/hard-of-hearing students. The results indicated that the CBM deaf/hard-of-hearing students and the CBM and non-CBM hearing students made more progress in solving the subtraction problems than the non-CBM deaf/hard-of-hearing students. The results also showed that there were no significant differences between the CBM deaf/hard-of-hearing and the non-CBM hearing students; and there were no significant differences between the CBM and non-CBM hearing students. The results revealed that the CBM hearing students achieved significantly higher post-test scores than the CBM deaf/hard-of-hearing students. However, the CBM deaf/hard-of-hearing students obtained a significantly higher gain score compared to the CBM and non-CBM hearing students. Implications for teachers and suggestions for future research are discussed in this paper.

    The modern counting instrumentation has largely obviated the need for separation processes in the radiochemical analysis but problems in low-level radioactivity measurement, environmental-type analyses, and special situations caused in the last years a renaissance of the need for separation techniques. Most of the radiochemical procedures, based on the classic works of the Manhattan Project chemists of the 1940's, were published in the National Nuclear Energy Series (NNES). Improvements such as new solvent extraction and ion exchange separations have been added to these methods throughout the years. Recently the Los Alamos Group have reissued their collected Radiochemical Procedures containing a short summary and review of basic inorganic chemistry - 'Chemistry of the Elements on the Basis of Electronic Configuration'.

    In nonnuclear business, administrative procedures bring to mind such mundane topics as filing correspondence and scheduling vacation time. In the nuclear industry, on the other hand, administrative procedures play a vital role in assuring the safe operation of a facility. For some time now, industry focus has been on improving technical procedures. Significant efforts are under way to produce technical procedure requires that a validated technical, regulatory, and administrative basis be developed and that the technical process be established for each procedure. Producing usable technical procedures requires that procedure presentation be engineered to the same human factors principles used in control room design. The vital safety role of administrative procedures requires that they be just as sound, just a rigorously formulated, and documented as technical procedures. Procedure programs at the Tennessee Valley Authority and at Boston Edison's Pilgrim Station demonstrate that human factors engineering techniques can be applied effectively to technical procedures. With a few modifications, those same techniques can be used to produce more effective administrative procedures. Efforts are under way at the US Department of Energy Nuclear Weapons Complex and at some utilities (Boston Edison, for instance) to apply human factors engineering to administrative procedures: The techniques being adapted include the following

    Peripherally inserted central catheters are venous devices intended for short to medium periods of intravenous treatment. Positioning of the catheter tip at the cavoatrial junction is necessary for optimum performance of a peripherally inserted central catheter. In this study, safety, effectiveness and cost-effectiveness of electrocardiographic-guided peripherally inserted central catheter positioning in a Dutch teaching hospital were evaluated. All patients who received a peripherally inserted central catheter in 2016 using electrocardiographic guidance were compared to those where fluoroscopy guidance was used in a prospective non-randomized cohort study. Relevant data were extracted from electronic health records. Cost-effectiveness analysis was performed. A total of 162 patients received a peripherally inserted central catheter using fluoroscopy guidance and 103 patients using electrocardiographic guidance in 2016. No significant difference was found in malposition, infection or other complications between these groups. Due to personnel reduction and omission of fluoroscopy costs, cost reduction for each catheter insertion was €120 in the first year and, as a result of discounted acquisition costs, €190 in subsequent years. The positioning results and complication rate are comparable to the previously reported literature. The cost reduction may vary in different hospitals. Other benefits of the electrocardiographic-guided technique are omission of X-ray exposure and improved patient service. Implementation of electrocardiographic-guided tip positioning for peripherally inserted central catheter was safe and effective in this study and led to an improved high value and cost-conscious care.

    malfunction is the most likely signal of embolization, since patients are usually asymptomatic. OBJECTIVE: To report the method of removing intravascular foreign bodies, catheters with the use of various endovascular techniques and procedures. METHODS: This is a two-year retrospective study of 12 patients: seven women and five men. The average age was 29 years (ranging from two months to 65 years. RESULTS: Technical performance was 100% successful. Ten port-a-caths, one intra-cath and one PICC were extracted. The most common sites for the lodging of one of the ends of the intravascular foreign bodies were the right atrium (41.6% and the right ventricle (33.3%. In 100% of the cases, only one venous access was used for extraction of foreign bodies, and in 91.6% of the cases (11 catheters the femoral access was used. The loop-snare was used in 10 cases (83.3%. The most common cause of intravascular foreign body insertion was a catheter fracture, which occurred in 66.6% of the cases (eight cases. One major complication, the atrial fibrillation, occurred (8.3%, which was related to the intravascular foreign body extraction. The mortality rate in 30 days was zero. CONCLUSION: Percutaneous retrieval of intravascular foreign bodies is considered gold standard treatment because it is a minimally invasive, relatively simple, safe procedure, with low complication rates compared to conventional surgical treatment

    The Department of Energy has used Artificial Intelligence of ''AI'' concepts to develop two powerful new computer-based techniques to enhance safety in nuclear applications. The Procedure Generation System, and the Procedure Verification System, can be adapted to other commercial applications, such as a manufacturing plant. The Procedure Generation System can create a procedure to deal with the off-normal condition. The operator can then take correct actions on the system in minimal time. The Verification System evaluates the logic of the Procedure Generator's conclusions. This evaluation uses logic techniques totally independent of the Procedure Generator. The rapid, accurate generation and verification of corrective procedures can greatly reduce the human error, possible in a complex (stressful/high stress) situation

     EUS-guided biliary drainage (EUS-BD) and rendezvous (EUS-RV) are acceptable rescue options for patients with failed endoscopic retrograde cholangiopancreatography (ERCP). However, there are limited training opportunities at most centers owing to low case volumes. The existing models do not replicate the difficulties encountered during EUS-BD. We aimed to develop and validate a model for stepwise learning of EUS-BD and EUS-RV, which replicates the actual EUS-BD procedures.  A hybrid model was created utilizing pig esophagus and stomach, with a synthetic duodenum and biliary system. The model was objectively assessed on a grade of 1 - 4 by two experts. Twenty-eight trainees were given initial training with didactic lectures and live procedures. This was followed by hands-on training in EUS-BD and EUS-RV on the hybrid model. Trainees were assessed for objective criteria of technical difficulties.  Both the experts graded the model as very good or above for all parameters. All trainees could complete the requisite steps of EUS-BD and EUS-RV in a mean time of 11 minutes (8 - 18 minutes). Thirty-six technical difficulties were noted during the training (wrong scope position, 13; incorrect duct puncture, 12; guidewire related problems, 11). Technical difficulties peaked for EUS-RV, followed by hepaticogastrostomy (HGS) and choledochoduodenostomy (CDS) (20, 9, and 7, P  = 0.001). At 10 days follow-up, nine of 28 trainees had successfully performed three EUS-RV and seven EUS-BD procedures independently.  The Mumbai EUS II hybrid model replicates situations encountered during EUS-RV and EUS-BD. Stepwise mentoring improves the chances of success in EUS-RV and EUS-BD procedures.

    To systematically review studies concerning imaging-guided minimally-invasive breast cancer treatments. An online database search was performed for English-language articles evaluating percutaneous breast cancer ablation. Pooled data and 95% confidence intervals (CIs) were calculated. Technical success, technique efficacy, minor and major complications were analysed, including ablation technique subgroup analysis and effect of tumour size on outcome. Forty-five studies were analysed, including 1,156 patients and 1,168 lesions. Radiofrequency (n=577; 50%), microwaves (n=78; 7%), laser (n=227; 19%), cryoablation (n=156; 13%) and high-intensity focused ultrasound (HIFU, n=129; 11%) were used. Pooled technical success was 96% (95%CI 94-97%) [laser=98% (95-99%); HIFU=96% (90-98%); radiofrequency=96% (93-97%); cryoablation=95% (90-98%); microwave=93% (81-98%)]. Pooled technique efficacy was 75% (67-81%) [radiofrequency=82% (74-88); cryoablation=75% (51-90); laser=59% (35-79); HIFU=49% (26-74)]. Major complications pooled rate was 6% (4-8). Minor complications pooled rate was 8% (5-13%). Differences between techniques were not significant for technical success (p=0.449), major complications (p=0.181) or minor complications (p=0.762), but significant for technique efficacy (p=0.009). Tumour size did not impact on variables (p>0.142). Imaging-guided percutaneous ablation techniques of breast cancer have a high rate of technical success, while technique efficacy remains suboptimal. Complication rates are relatively low. • Imaging-guided ablation techniques for breast cancer are 96% technically successful. • Overall technique efficacy rate is 75% but largely inhomogeneous among studies. • Overall major and minor complication rates are low (6-8%).

    In this study optimization of procedures and standardization of Instrumental Neutron Activation Analysis (INAA) methods were carried out for the determination of the elements arsenic, chromium, cobalt, iron, rubidium, scandium, selenium and zinc in biological materials. The aim is to validate the analytical methods for future accreditation at the National Institute of Metrology, Quality and Technology (INMETRO). The 2 k experimental design was applied for evaluation of the individual contribution of selected variables of the analytical procedure in the final mass fraction result. Samples of Mussel Tissue Certified Reference Material and multi-element standards were analyzed considering the following variables: sample decay time, counting time and sample distance to detector. The standard multi-element concentration (comparator standard), mass of the sample and irradiation time were maintained constant in this procedure. By means of the statistical analysis and theoretical and experimental considerations it was determined the optimized experimental conditions for the analytical methods that will be adopted for the validation procedure of INAA methods in the Neutron Activation Analysis Laboratory (LAN) of the Research Reactor Center (CRPq) at the Nuclear and Energy Research Institute (IPEN - CNEN/SP). Optimized conditions were estimated based on the results of z-score tests, main effect and interaction effects. The results obtained with the different experimental configurations were evaluated for accuracy (precision and trueness) for each measurement. (author)

    The advantages and disadvantages of commonly used training techniques in relation to cost-effective, prevention-oriented Quality Assurance are examined. Important questions are whether training techniques teach cost effectiveness and whether the techniques are, themselves, cost effective. To answer these questions, criteria for evaluating teaching techniques for cost effectiveness were developd, and then commonly used techniques are evaluated in terms of specific training program objectives. Motivation of personnel is also considered important to the success of a training program, and methods are outlined by which recognition of the academic quality of industrial training can be used as a motivational technique

    1980-01-01

    The evaluation of several energy-dependent neutron cross sections which are of importance for practical applications is considered. The evaluation process is defined as the procedure which is used to derive the best knowledge of these cross sections based on the available direct experimental data information, and, using theoretical models, on the auxiliary data base. The experimental data base represents a multiple overdetermination of the unknown cross sections with various correlations between the measured values. Obtaining the least-squares estimator is considered as the standard mathematical procedure to derive a consistent set of evaluated cross section values. Various approximations made in order to avoid the monstrous system of normal equations are considered and the feasibility of the exact solution is demonstrated. The variance-covariance of the result, its reliability and the improvements obtained in iterative steps are discussed. Finally, the inclusion of auxiliary, supplementary information is considered. 45 references

    Objective: To assess the value of rotation digital subtraction angiography combined with the adjusting of patient's position in performing the interventional procedure for complicated intracranial aneurysms. Methods: Cerebral angiography in both anteroposterior and lateral positions as well as rotational cerebral angiography were carried out in 25 patients by using GE INNOVA 3100 digital subtraction angiography system. The image qualities, the technical feasibility and the operation success rate were analyzed. Results: Intracranial aneurysms were detected in 16 patients on anteroposterior position and lateral position angiography. In 9 patients the anatomic relationship between the aneurysms and the related arteries could not be clearly judged on both anteroposterior position and lateral position angiography images, while it could be well displayed on rotational angiographic images. In two interventional procedures the DSA unit working parts could not reach the optimal position indicated by the 3D-reconstruction images, and the patient's head position had to be adjusted with the help of a fixing support in order to let the operation be managed successfully. Conclusion: The rotation digital subtraction angiography combined with the adjusting of patient's head position can compensate the limitation of DSA unit mechanical working extent, therefore, the interventional procedures can be successfully performed with the patient lying in an ideal and optimal position.

In addition, some children with autism lack the ability of spontaneously seeking to share enjoyment, interests, or achievements with other people (e.g., a lack of showing, bringing, or pointing out objects of interest to other people. The aim of the study was to use ABA teaching techniques such as script and script fading procedure and activity schedule to teach three-year-old girl with autism spontaneous social interaction and shape joint attention skills. The result shows that ABA techniques were very effective in teaching many verbal skills such as answering questions, making requests, initiating conversation and asking question. Comparison made after implemented teaching procedure shows her initiating of joint attention skill (IJA is at the appropriate level for her age.

  6. Teaching chemistry with sustainability

    Full Text Available Increased awareness on a critical association between the natural environment and human development gave rise multiple projects, aiming to protect the natural environment and to preserve it for future generations. Chemists must be acquainted with the principles of green chemistry and the need to practice experimental chemistry with cleaner chemical reactions and sustainability. This is a major concern for all the educators forming new professionals within the Chemistry, Pharmacology and Biology curricula in the Faculty for Higher Studies Zaragoza from the National Autonomous University of Mexico. With this in mind, we start our teachings explaining from the very beginning, how important it is to perform microscale techniques and to follow the principles of green chemistry in the Basic Science Laboratory. Furthermore, we have modified, designed and evaluated working procedures related with chemical synthesis, kinetics and calorimetry. By doing this, we managed to greatly reduce the amount of reagents required and residues generated. Some laboratory reagents have been substituted with renewable substances. We have also included in our programme a regular treatment of residues generated during everyday laboratory work. Our goal is to emphasize the importance of minimizing the environmental impact of chemistry and to prepare environmentally concerned professionals who keep sustainability as main priority and perform chemistry procedures with good laboratory practice routines.

    This study was designed to establish the essential hand surgery procedures that should be mastered by graduating plastic surgery residents. This framework can then be used as a guideline for developing Objective Structured Assessment of Technical Skill to teach technical skills in hand surgery. Ten expert hand surgeons were surveyed regarding the essential hand surgery procedures that should be mastered by graduating plastic surgery residents. The top 10 procedures from this survey were then used to survey all 89 Accreditation Council for Graduate Medical Education-approved plastic surgery program directors. There was a 69 percent response rate to the program director survey (n = 61). The top nine hand surgery procedures included open carpal tunnel release, open A1 pulley release, digital nerve repair with microscope, closed reduction and percutaneous pinning of metacarpal fracture, excision of dorsal or volar ganglion, zone II flexor tendon repair with multistrand technique, incision and drainage of the flexor tendon sheath for flexor tenosynovitis, flexor tendon sheath steroid injection, and open cubital tunnel release. Surgical educators need to develop objective methods to teach and document technical skill. The Objective Structured Assessment of Technical Skill is a valid method for accomplishing this task. There has been no consensus regarding which hand surgery procedures should be mastered by graduating plastic surgery residents. The authors have identified nine procedures that are overwhelmingly supported by plastic surgery program directors. These nine procedures can be used as a guideline for developing Objective Structured Assessment of Technical Skill to teach and document technical skills in hand surgery.

  9. August Dvorak (1894-1975): Early expressions of applied behavior analysis and precision teaching

    Science.gov (United States)

    Joyce, Bonnie; Moxley, Roy A.

    1988-01-01

    August Dvorak is best known for his development of the Dvorak keyboard. However, Dvorak also adapted and applied many behavioral and scientific management techniques to the field of education. Taken collectively, these techniques are representative of many of the procedures currently used in applied behavior analysis, in general, and especially in precision teaching. The failure to consider Dvorak's instructional methods may explain some of the discrepant findings in studies which compare the efficiency of the Dvorak to the standard keyboard. This article presents a brief background on the development of the standard (QWERTY) and Dvorak keyboards, describes parallels between Dvorak's teaching procedures and those used in precision teaching, reviews some of the comparative research on the Dvorak keyboard, and suggests some implications for further research in applying the principles of behavior analysis.

    2017-03-01

    Full Text Available Teaching Learning Based Optimization (TLBO is one of the non-traditional techniques to simulate natural phenomena into a numerical algorithm. TLBO mimics teaching learning process occurring between a teacher and students in a classroom. A parameter named as teaching factor, TF, seems to be the only tuning parameter in TLBO. Although the value of the teaching factor, TF, is determined by an equation, the value of 1 or 2 has been used by the researchers for TF. This study intends to explore the effect of the variation of teaching factor TF on the performances of TLBO. This effect is demonstrated in solving structural optimization problems including truss and frame structures under the stress and displacement constraints. The results indicate that the variation of TF in the TLBO process does not change the results obtained at the end of the optimization procedure when the computational cost of TLBO is ignored.

    A method is proposed for the extraction and determination of organomercury compounds and Hg(II) in seawater samples by headspace solid-phase microextraction (HS-SPME) combined with capillary gas chromatography-microwave-induced plasma atomic emission spectrometry. The mercury species were derivatized with sodium tetraphenylborate, sorbed on a polydimethylsiloxane-coated fused-silica fibre, and desorbed in the injection port of the GC, in splitless mode. Experimental design methodology was used to evaluate the effect of six HS-SPME-derivatization variables: sample volume, NaBPh{sub 4} volume, pH, sorption time, extraction-derivatization temperature, and rate of stirring. Use of a multicriterion decision-making approach, with the desirability function, enabled determination of the optimum working conditions of the procedure for simultaneous analysis of three mercury species.

    A concept of using thin-layer chromatography to multicomponent sample preparation for quantitative determination of solutes followed by instrumental technique is presented. Thin-layer chromatography (TLC) is used to separate chosen substances and their internal standard from other components (matrix) and to form a single spot/zone containing them at the solvent front position. The location of the analytes and internal standard in the solvent front zone allows their easy extraction followed by quantitation by HPLC. Copyright © 2017 Elsevier B.V. All rights reserved.

    We present in this work a review of the conventional quantization procedure, the proposed by I.E. Segal and a new quantization procedure similar to this one for use in non linear problems. We apply this quantization procedures to different potentials and we obtain the appropriate equations of motion. It is shown that for the linear case the three procedures exposed are equivalent but for the non linear cases we obtain different equations of motion and different energy spectra. (Author) 16 refs

    After referring to the regulations governing the 'systematic ambience monitoring' in the basic nuclear facilities, the main radiation detection, signalization and alarm devices existing at present in these facilities of the Saclay Nuclear Study Centre are described. The analysis of the operating defects of the measuring channels and detection possibilities leads to the anomalies being classified in two separate groups: the anomalies of the logical 'all or nothing' type of which all the possible origins are integrated into a so-called 'continuity' line and the evolutive anomalies of various origins corresponding to poor functioning extending possibly to a complete absence of signal. The techniques for testing the detection devices of the radiation monitoring board set up in the 'Departement de Rayonnements' at the Saclay Nuclear Study Centre are also described [fr

    Teachers need various types of knowledge in order to deliver various fraction concepts at elementary level. In this paper, Balls' framework (2008) or, Mathematical Knowledge for Teaching (MKT) is used as benchmark guideline. This paper investigates and explores component of MKT knowledge among eight experienced teachers of the primary school. Data was collected using paper pencil test, interview and video recording. This paper, narrowed to teacher's knowledge and their practices while teaching of various fractions concepts using diagrammatical approach in present of MKT. The data gathered from teachers were analyzed using thematic analysis techniques. The results indicated that teachers lack various components of MKT knowledge as a proposal by various researchers and assumed that teaching as procedural more than enough due to lack of deep understanding of mathematics and the various types of MKT is not required due to the present of practices in the mathematics classroom.

    Purpose: SRS is an effective non-invasive alternative treatment modality with minimal-toxicity used to treat patients with medically/surgically refractory trigeminal neuralgia root(TNR) or those who may not tolerate surgical intervention. We present our linac-based SRS procedure for TNR treatment and simultaneously report our clinical outcomes. Methods: Twenty-eight TNR-patients treated with frame-based SRS at our institution (2009–2015) with a single-fraction point-dose of 60-80Gy to TNR were included in this IRB-approved study. Experienced neurosurgeon and radiation oncologist delineated the TNR on 1.0mm thin 3D-FIESTA-MRI that was co-registered with 0.7mm thin planning-CT. Treatment plans were generated in iPlan (BrainLAB) with a 4-mm diameter cone using 79 arcs with differential-weighting for Novalis-TX 6MV-SRS(1000MU/min) beam and optimized to minimize brainstem dose. Winston-Lutz test was performed before each treatment delivery with sub-millimeter isocenter accuracy. Quality assurance of frame placement was maintained by helmet-bobble-measurement before simulation-CT and before patient setup at treatment couch. OBI-CBCT scan was performed for patient setup verification without applying shifts. On clinical follow up, treatment response was assessed using Barrow Neurological Institute Pain Intensity Score(BNI-score:I–V). Results: 26/28 TNR-patients (16-males/10-females) who were treated with following single-fraction point-dose to isocenter: 80Gy(n=22),75Gy(n=1),70Gy(n=2) and 60Gy(n=1, re-treatment) were followed up. Median follow-up interval was 8.5-months (ranged:1–48.5months). Median age was 70-yr (ranged:43–93-yr). Right/left TNR ratio was 15/11. Delivered total # of average MUs was 19034±1204. Average beam-on-time: 19.0±1.3min. Brainstem max-dose and dose to 0.5cc were 13.3±2.4Gy (ranged:8.1–16.5Gy) and 3.6±0.4Gy (ranged:3.0–4.9Gy). On average, max-dose to optic-apparatus was ≤1.2Gy. Mean value of max-dose to eyes/lens was 0.26Gy/0.11Gy

    users at the hospitals. Commissioning is one of the most important parts of the entire QA programme for both the RTPS and the planning process. Commissioning involves testing of system functions, documentation of the different capabilities and verification of the ability of the dose calculation algorithms to reproduce measured dose calculations. The current report is limited to treatment simulation tests for external high-energy photon beams that are performed prior to clinical use of RTPS. The report deals with the verification of the dose calculations through commissioning tests that cover typical treatment techniques only. This report also summarizes the results of a pilot study of the clinical commissioning recommendations that was performed by the participants of the Coordinated Research Project at their home institutions. The summary of the pilot study is available to medical physicists as an example of the implementation of the clinical commissioning procedures for RTPSs at their hospitals. Issues related to intensity modulated radiation therapy (IMRT) or other specialized techniques such as stereotactic radiosurgery are not addressed in this clinical commissioning report. While recognizing the specific scope of this report, this publication is useful to the purchasers of RTPSs in any country although they may have to perform tests beyond those described in this report to meet the needs of specialized techniques that have not been addressed here

    International Nuclear Information System (INIS)

    Forestner, J.E.

    1987-01-01

    Anesthetic techniques for neurodiagnostic studies and radiation therapy have been recently reviewed, but anesthetic involvement in thoracic and abdominal radiology has received little attention. Patient reactions to radiologic contrast media may be of concern to the anesthesiologist, who is often responsible for injecting these agents during diagnostic procedures, and thus is included in this discussion. Finally, the difficulties of administering anesthesia for magnetic resonance imaging (MRI) scans are outlined, in an effort to help anesthesiologist to anticipate problems with this new technologic development. Although there are very few indications for the use of general anesthesia for diagnostic radiologic studies in adults, most procedures performed with children, the mentally retarded, or the combative adult require either heavy sedation or general anesthesia. In selecting an anesthetic technique for a specific procedure, both the patient's disease process and the requirements of the radiologist must be carefully balanced

    The purpose of this study was to survey pediatric dentistry advanced education program directors regarding the teaching of behavior management techniques. Surveys were mailed to all (65) advanced education programs in the United States. Follow-up mailings were sent to nonrespondents. The survey contained items on program demographics and the program's teaching of communicative and pharmacologic techniques. Information was also obtained on informed consent and parental presence in the operatory. Surveys were returned by 54 programs. Two programs declined to respond because they had not yet accepted or certified residents. The final response rate was 86%. The mean percentage (+/- SD) of total didactic time devoted to behavior management was 13% (+/-9.5). Communicative techniques were taught as "acceptable" by 98% of programs, with the exception of the hand-over-mouth exercise (HOME), which was taught as "unacceptable" by 54% of programs. Active and passive immobilization of sedated and nonsedated children was taught as "acceptable" by 76% to 98% of programs. All programs taught that pharmacologic techniques (nitrous oxide, conscious sedation, general anesthesia) are "acceptable." There was little evidence that the teaching of behavior management techniques had changed over the previous 5 years, nor that it is likely to change in the near future. Parental presence in the operatory was common for some procedures, particularly among younger children. Most programs do not teach HOME as an acceptable behavior management technique. The amount of curricular time devoted to behavior management is not likely to change appreciably in the near future.

    2009-06-01

    Universal or "broad-range" PCR-based ribosomal DNA (rDNA) was performed on a collection of 58 isolates (n = 30 bacteria + 28 fungi), originating from environmental air from several locations within a busy clinical microbiology laboratory, supporting a university teaching hospital. A total of 10 bacterial genera were identified including both Gram-positive and Gram-negative genera. Gram-positive organisms accounted for 27/30 (90%) of total bacterial species, consisting of seven genera and included (in descending order of frequency) Staphylococcus, Micrococcus, Corynebacterium, Paenibacillus, Arthrobacter, Janibacter and Rothia. Gram-negative organisms were less frequently isolated 3/30 (10%) and comprised three genera, including Moraxella, Psychrobacter and Haloanella. Eight fungal genera were identified among the 28 fungal organisms isolated, including (in descending order of frequency) Cladosporium, Penicillium, Aspergillus, Thanatephorus, Absidia, Eurotium, Paraphaeosphaeria and Tritirachium, with Cladosporium accounting for 10/28 (35.7%) of the total fungal isolates. In conclusion, this study identified the presence of 10 bacterial and eight fungal genera in the air within the laboratory sampled. Although this reflected diversity of the microorganisms present, none of these organisms have been described previously as having an inhalational route of laboratory-acquired infection. Therefore, we believe that the species of organisms identified and the concentration levels of these airborne contaminants determined, do not pose a significant health and safety threat for immunocompotent laboratory personnel and visitors.

    The purpose of this study was to survey directors of predoctoral pediatric dentistry programs regarding the teaching of behavior management techniques. Surveys were mailed to all 56 dental schools in the United States. Follow-up mailings were sent to nonrespondents. The survey contained items on program demographics and the program's teaching of communicative and pharmacologic techniques. Information was also obtained on informed consent and parental presence in the operatory. Surveys were returned by 48 schools. Two schools declined to respond because they had not yet accepted or graduated students. The final response rate was 89%. The mean (+/-SD) percentage of total didactic time devoted to behavior management was 12% (+/-6). Communicative techniques were taught as "acceptable" by 96% to 100% of programs, with the exception of the hand-over-mouth exercise (HOME). HOME was taught as "unacceptable" by 62% of programs. Active and passive immobilization of sedated and nonsedated children was taught as "acceptable" by 69% to 85% of programs. Sixty-seven percent to 98% of programs taught that pharmacologic techniques (nitrous oxide, conscious sedation, general anesthesia) are "acceptable." There was little evidence that the teaching of behavior management techniques had changed over the previous 5 years, nor that they were likely to change in the near future. Parental presence in the operatory was common for some procedures, particularly among younger children. Predoctoral programs teach as acceptable communicative and pharmacologic management techniques, with the exception of HOME. Predoctoral program directors report they are not likely to increase the amount of curricular time devoted to behavior management in the near future.

    Our goal was to determine whether simulation combined with didactic training improves sterile technique during ultrasound (US)-guided central venous catheter (CVC) insertion compared with didactic training alone among novices. We hypothesized that novices who receive combined didactic and simulation-based training would perform similarly to experienced residents in aseptic technique, knowledge, and perception of comfort during US-guided CVC insertion on a simulator. Seventy-two subjects were enrolled in a randomized, controlled trial of an educational intervention. Fifty-four novices were randomized into either the didactic group or the simulation combined with didactic group. Both groups received didactic training but the simulation combined with didactic group also received simulation-based CVC insertion training. Both groups were tested by demonstrating US-guided CVC insertion on a simulator. Aseptic technique was scored on 8 steps as "yes/no" and also using a 7-point Likert scale with 7 being "excellent technique" by a rater blinded to subject randomization. After initial testing, the didactic group was offered simulation-based training and retesting. Both groups also took a pre- and posttraining test of knowledge and rated their comfort with US and CVC insertion pre- and posttraining on a 5-point Likert scale. Subsequently, 18 experienced residents also took the test of knowledge, rated their comfort level, and were scored while performing aseptic US-guided CVC insertion using a simulator. The simulation combined with didactic group achieved a 167% (95% confidence interval [CI] 133%-167%) incremental increase in yes/no scores and 115% (CI 112%-127%) incremental increase in Likert scale ratings on aseptic technique compared with novices in the didactic group. Compared with experienced residents, simulation combined with didactic trained novices achieved an increase in aseptic scores with a 33.3% (CI 16.7%-50%) increase in yes/no ratings and a 20% (CI 13

    There is no single ideal way of teaching epidemiology. Teaching can take place in different situations, and its techniques and content may differ. A good teaching programme is one that is geared to its students' needs, capacity, interests and preferences, and exploits available teaching situations and techniques to provide learning opportunities that will achieve the educational objectives. This paper reviews some features of the teaching of epidemiology inside and outside the classroom. It starts with a discussion of the main factors that affect the choice of methods and then deals in turn with conventional classroom methods, laboratory teaching (problem-solving and other exercises), self-instruction, problem-oriented projects, and distance learning. Separate consideration is then given to teaching in the hospital and in the field (with special attention to teaching in a community health center).

    Full Text Available We have proposed a method to assist children with coordination difficulties or dyspraxia to improve their handwriting skills. We have chosen an animation technique called ‘Rotoscopy’, a method that normally been used in animation and film production and adapted it to Rotoscopy Prehandwriting Interface (RPI prototypes using the interactive whiteboard (IWB as interaction device. The motivation of this research is to discover how efficient if Rotoscopy is used beyond its normal purposes? Does it give benefits in terms of behavioural and motivational aspect rather than commercial and profit point of view? Implementation of RPI prototypes has taken place through series of workshops with a teacher and a group of children with handwriting difficulties at a special education school in Caerphilly, Cardiff, United Kingdom. In the workshops children were given pre-handwriting activities in two different environments. They have been trained to use RPI prototypes and IWB as well as using pen and paper. Their activities and action has been observed and recorded using video camera. Evaluation method is based-on video analysis of children’s pre-handwriting result and their reaction and motivation during the workshop. It was learnt that majority of children who used RPI prototypes and IWB have produced better results in terms of accuracy of the drawing as compared to results of pen and paper activities. Furthermore the children are more motivated to use the prototypes and IWB rather than using pen and paper. The study’s contribution includes offering a new way to improve children’s prehandwriting skills using computer animation technique and touch-based devices.

    2014-01-01

    This paper shows the importance of the methodization in teaching facial dermal filling on the training of physicians who intend to work or are already working in the area of facial aesthetics. The methodology is based on the procedures performed in Iz Clinic of Plastic Surgery from 2007 to 2010, where the results of the use of dermal filling products were observed. We chose the hyaluronic acid for the methodization of education. Even being a safe procedure, the dermal filling needs to be done by trained professionals because some complications may occur. The theoretical discussion of facial anatomy, physiology and classification of aging, rheological characteristics of products and application techniques underpin the practical part, in which the live demo or supervision of the procedure is performed. The idealization of classes, both theoretical and practical, proposed in this work proved to be of great value in teaching physicians. The success of this method can be seen from the results achieved by students and by observing the drop in reports of adverse effects. After learning the techniques of facial dermal filling with products based on hyaluronic acid, a doctor may perform this therapy with other fillers, with harmonious results.

  15. Creativity in Teaching

    2016-12-01

    Full Text Available Background: The research of effective teaching is an actual problem of modern linguistics because of active promotion of its unequal manifestations and amplification of the functional load in various sectors of society. Purpose: The purpose of the analysis is to determine the qualifying and classifying features of creative and effective teacher. Results: A foreign language teacher should develop an attractive manner of communication with students. His straightforward behaviour may be expressed in non-verbal communication, through using sympathetic gestures, voice variation, smile and verbal communication expressed through a good sense of humour, personal examples, using words “we” and “our”. This manner of communication provides for a favourable condition for an atmosphere of open-mindedness and mutual understanding. A creative attitude of a teacher towards the organization of a teaching process is related to the updating of the features like fluidity understood as a spontaneous reaction during classes. The teacher as a person who creates and organises a teaching unit should possess leader’s features. Gaining a position of a group leader provides for an opportunity to arrange undisturbed work without any communication misunderstandings. Learners are given precisely formulated instructions, do the tasks in an effective and efficient manner. Therefore, it should be emphasized that a creative teacher should enjoy the features of a reflective practitioner. Being which constantly learns and improves his qualifications, studies and examines his teaching techniques, introduces changes and some time or another revisits his “beaten tracks”, breaking down routine and habits. Getting rid of habits and routines, teaching in harmony with himself, as well as appropriate selection of methods do guarantee a high comfort of work in a well-motivated group, where due to teacher’s creativity a teaching success is achieved, as expressed in

    Full Text Available The human being started as a self-educated person, this way managing to improve his living. For his descendants to avoid failures, he started to share his ancestors’ experience. When some people’s knowledge acquirement became big, they were called the sages, and among of them became eventually teachers, that took the role of transmitting the useful information related to life environmental conditions they lived. In time, their needs became more and more complex and their knowledge deeper. In the act of teaching itself, teachers create a shortcut between necessity and solving it, going beyond failures. Obviously, the present society is technologized, where the human being uses technology but he also searches for himself. This quest should be naturally performed with the help of the educator, of the experienced student, so that he could shape the young man and make him feel good with himself and find his place within society. The current education system describes to younger people nothing more than the evolution of science, technique and art, starting with the first trials till our days. What is really mandatory for us is to find a way where the educational system could become again a necessity for a person and not a way to keep very many people busy, while they can be intellectually and psycho-emotionally shaped.

  17. Teaching Willmore

    Directory of Open Access Journals (Sweden)

    James Evans

    2014-03-01

    Full Text Available Teaching Aphra Behn’s The Rover for nearly four decades, I have witnessed a considerable shift in students’ attitudes toward the play, especially toward Willmore. More positive about his character in the 1970s and 1980s, they have had a much more negative assessment since then. The only available video version, the Women’s Theatre Trust production, compounds my pedagogical problem through filming techniques and choice of actor; emphasizing male violence against women, its interpretation parallels feminist criticism of the 1990s. Asking students to examine theater history may lead them to see that Behn does not completely match this ideological paradigm. The original casting featured William Smith as Willmore, and learning about his performances in the company at Dorset Garden may help students recognize that the character was conceived to emphasize his comic dimension as a flawed, desirable partner for Hellena. Understanding Behn’s comedy within the collaborative enterprise of Restoration theater may complicate their views of Willmore.

    2011-01-01

    Several reports on science education suggest that students at all levels learn better if they are immersed in a project that is long term, yielding results that require analysis and interpretation. I describe a 12-wk laboratory project suitable for upper-level undergraduates and first-year graduate students, in which the students molecularly locate and map a gene from Drosophila melanogaster called dusky and one of dusky's mutant alleles. The mapping strategy uses restriction fragment length polymorphism analysis; hence, students perform most of the basic techniques of molecular biology (DNA isolation, restriction enzyme digestion and mapping, plasmid vector subcloning, agarose and polyacrylamide gel electrophoresis, DNA labeling, and Southern hybridization) toward the single goal of characterizing dusky and the mutant allele dusky(73). Students work as individuals, pairs, or in groups of up to four students. Some exercises require multitasking and collaboration between groups. Finally, results from everyone in the class are required for the final analysis. Results of pre- and postquizzes and surveys indicate that student knowledge of appropriate topics and skills increased significantly, students felt more confident in the laboratory, and students found the laboratory project interesting and challenging. Former students report that the lab was useful in their careers.
