Current surgical education relies on simulated educational experiences or didactic sessions to teach low-frequency clinical events such as abdominal compartment syndrome (ACS). The purpose of this pilot study was to evaluate if simulation would improve performance and knowledge retention of ACS better than a didactic lecture. Nineteen general surgery residents were block randomized by postgraduate year level to a didactic or a simulation session. After 3 months, all residents completed a knowledge assessment before participating in an additional simulation. Two independent reviewers assessed resident performance via audio-video recordings. No baseline differences in ACS experience were noted between groups. The observational evaluation demonstrated a significant difference in performance between the didactic and simulation groups: 9.9 vs 12.5, P = .037 (effect size = 1.15). Knowledge retention was equivalent between groups. This pilot study suggests that simulation-based education may be more effective for teaching the basic concepts of ACS.

Full Text Available Reassessment of the existing didactic-methodological organization within the University lectures as well as the role of students and University lecturers is a result of the current process of higher education reforms. The advancement of pedagogical and didactic-methodological competences of university lecturers represents an imperative in reaching a high quality education. The results of this research may function as a starting point in the self-evaluation of University lecturers. The point of this work was to present didactic and methodical elements of contemporary university teaching, according to Bologna concept of higher education, and position of students. Taking into consideration the very definition and didactic methodological structure and legality of teaching, researches related to representation of individual didactic and methodical elements of contemporary university teaching are presented, which relate to forms of teaching, methods of teaching and application of teaching and technical aids. In the context of the current reform of the high education and considering the Bologna Declaration it could be concluded that contemporary university teaching is marked with cooperative interactive teaching in which the position of students and teachers is defined as partnership.

Asynchronous, computer based instruction is cost effective, allows self-directed pacing and review, and addresses preferences of millennial learners. Current research suggests there is no significant difference in learning compared to traditional classroom instruction. Data are limited for novice learners in emergency medicine. The objective of this study was to compare asynchronous, computer-based instruction with traditional didactics for senior medical students during a week-long intensive course in acute care. We hypothesized both modalities would be equivalent. This was a prospective observational quasi-experimental study of 4th year medical students who were novice learners with minimal prior exposure to curricular elements. We assessed baseline knowledge with an objective pre-test. The curriculum was delivered in either traditional lecture format (shock, acute abdomen, dyspnea, field trauma) or via asynchronous, computer-based modules (chest pain, EKG interpretation, pain management, trauma). An interactive review covering all topics was followed by a post-test. Knowledge retention was measured after 10 weeks. Pre and post-test items were written by a panel of medical educators and validated with a reference group of learners. Mean scores were analyzed using dependent t-test and attitudes were assessed by a 5-point Likert scale. 44 of 48 students completed the protocol. Students initially acquired more knowledge from didactic education as demonstrated by mean gain scores (didactic: 28.39% ± 18.06; asynchronous 9.93% ± 23.22). Mean difference between didactic and asynchronous = 18.45% with 95% CI [10.40 to 26.50]; p = 0.0001. Retention testing demonstrated similar knowledge attrition: mean gain scores -14.94% (didactic); -17.61% (asynchronous), which was not significantly different: 2.68% ± 20.85, 95% CI [-3.66 to 9.02], p = 0.399.

The learning and development of technical skills are paramount for neurosurgical trainees. External influences and a need for maximizing efficiency and proficiency have encouraged advancements in simulator-based learning models. To confirm the importance of establishing an educational curriculum for teaching minimally invasive techniques of pedicle screw placement using a computer-enhanced physical model of percutaneous pedicle screw placement with simultaneous didactic and technical components. A 2-hour educational curriculum was created to educate neurosurgical residents on anatomy, pathophysiology, and technical aspects associated with image-guided pedicle screw placement. Predidactic and postdidactic practical and written scores were analyzed and compared. Scores were calculated for each participant on the basis of the optimal pedicle screw starting point and trajectory for both fluoroscopy and computed tomographic navigation. Eight trainees participated in this module. Average mean scores on the written didactic test improved from 78% to 100%. The technical component scores for fluoroscopic guidance improved from 58.8 to 52.9. Technical score for computed tomography-navigated guidance also improved from 28.3 to 26.6. Didactic and technical quantitative scores with a simulator-based educational curriculum improved objectively measured resident performance. A minimally invasive spine simulation model and curriculum may serve a valuable function in the education of neurosurgical residents and outcomes for patients.

Solving today's complex hydrological problems requires originality, creative thinking and trans-disciplinary approaches. Hydrological education that was traditionally teacher centred, where the students look up to the teacher for expertise and information, should change to better prepare hydrologists to develop new knowledge and apply it in new contexts. An important first step towards this goal is to change the concept of education in the educators' minds. The results of an investigation to find out whether didactic training influences the beliefs of hydrology educators about their teaching styles is presented. Faculty of UNESCO-IHE has been offered a didactic certification program named university teaching qualification (UTQ). The hypothesis that UTQ training will significantly alter the teaching style of faculty at UNESCO-IHE from expert/formal authority traits towards facilitator/delegator traits was tested. A first survey was conducted among the entire teaching staff (total 101, response rate 58%). The results indicated that there are significantly higher traits of facilitator and delegator teaching styles among UTQ graduates compared to faculty who were not significantly trained in didactics. The second survey which was conducted among UTQ graduates (total 20, response rate 70%), enquiring after their teaching styles before and after UTQ, corroborated these findings.

DIDACTIC MODEL AS AN EDUCATIONAL TOOL APPLIED IN TEACHING OF CELL ANATOMY

Full Text Available The didactic models have a prominent role in the chemical and physical education. However, the use of this tool is still little explored in science teaching. In this article, we present a didactic proposal based on the use of representational didactic models to complement the teaching of cellular anatomy. The methodology was tested and evaluated by students of the seventh grade of elementary school in a public school in Tefe, Amazonas. Structured questionnaires were used to assess the perception of knowledge about cellular anatomy, difficulties in understanding the concepts and the importance of using didactic models for learning. The percentage of correct answers in the pre-test ranged from 15% to 54%, while the post-test, this rate was much higher, between 77% to 100%. The percentage of inadequate responses in the pretest demonstrates that traditional teaching activities are not efficient for the promotion of long-term knowledge. In contrast, high levels of correct answers in the post-test suggest that the incorporation of leisure activity - able to arouse curiosity, interest and active participation of students - complements effectively the teaching of anatomy Mobile. With this activity we observed that the educational model is a feasible strategy for effective understanding of the cytological aspects of plant and animal cells.

In the era of surgical resident work hour restrictions, the traditional apprenticeship model may provide fewer hours for neurosurgical residents to hone technical skills. Spinal dura mater closure or repair is 1 skill that is infrequently encountered, and persistent cerebrospinal fluid leaks are a potential morbidity. To establish an educational curriculum to train residents in spinal dura mater closure with a novel durotomy repair model. The Congress of Neurological Surgeons has developed a simulation-based model for durotomy closure with the ongoing efforts of their simulation educational committee. The core curriculum consists of didactic training materials and a technical simulation model of dural repair for the lumbar spine. Didactic pretest scores ranged from 4/11 (36%) to 10/11 (91%). Posttest scores ranged from 8/11 (73%) to 11/11 (100%). Overall, didactic improvements were demonstrated by all participants, with a mean improvement between pre- and posttest scores of 1.17 (18.5%; P = .02). The technical component consisted of 11 durotomy closures by 6 participants, where 4 participants performed multiple durotomies. Mean time to closure of the durotomy ranged from 490 to 546 seconds in the first and second closures, respectively (P = .66), whereby the median leak rate improved from 14 to 7 (P = .34). There were also demonstrative technical improvements by all. Simulated spinal dura mater repair appears to be a potentially valuable tool in the education of neurosurgery residents. The combination of a didactic and technical assessment appears to be synergistic in terms of educational development.

Comparative analysis of Klafki and Heimann's didactic models

Full Text Available A comparative analysis of Klafki's didactic thinking which is based on an analysis of different kinds of theories on the nature of education and Heimann's didactic which is based on the theory of teaching and learning shows that both are dealing with teaching in its entirety. Both authors emphasize the role of contents, methods, procedures and resources for material and formal education and both use anthropological and social reality as their starting point. According to Klafki, resources, procedures, and methods are in form of dependency where it is important to know what and why should something be learnt, whereas Heimann sees the same elements in the form of interdependency. Each of the didactic conceptions, from their point of view, define the position of goals and tasks in education as well as how to achieve them. Determination and formulation of objectives is a complex, responsible, and very difficult task, and a goal must be clearly defined, because it emanates the guidelines for the preparation of didactic methodology educational programs and their planning. The selection of content in didactic methodology scenarios of education and learning, are only possible if the knowledge, skills and abilities that are necessary for a student to develop are explicitly indicated. The question of educational goals is the main problem of didactics for only a clearly defined objective implicates the selection of appropriate methods and means for its achievement, and it should be a permanent task of the current didactic conception now and in the future.

This study surveyed didactic and clinical education in fluency disorders at undergraduate and graduate institutions in the United States that provide education in speech-language pathology to determine whether a previously observed reduction in requirements has continued since prior surveys (Yaruss, 1999; Yaruss & Quesal, 2002). The study involved a detailed questionnaire that was sent to 282 communication science and disorders departments. Questions examined didactic and clinical education, as well as faculty knowledge about fluency disorders. Comparisons with prior surveys revealed several findings, including (a) on average, programs have increased academic coursework and incorporated more practical sessions and competency-based testing in the classroom; (b) the number of faculty who possess extensive clinical experience with fluency disorders has decreased; and (c) although an increase in clinical requirements in fluency disorders was detected, the number of programs providing minimal education about fluency disorders remains high. Given an expanding scope of practice, many programs have continued to try to provide adequate education about fluency disorders. Still, direct clinical experiences are limited, and faculty expertise in this area has continued to decrease. To raise students' confidence and competence in fluency disorders, efforts beyond graduate work-or systemic changes in the profession-may be necessary.

Surgical residency contains an inadequate amount of hands-on training in the operating room and time constraints further make this type of education on the floor unlikely. Due to these deficits in residency training, private surgical courses outside of the established residency programmes are in high demand. Therefore, surgical residents must spend their own resources and time in addition to their residency training in order to receive adequate clinical exposure. Didactic approaches like problem-based learning have begun to influence our modern education. These novel education approaches along with visualisation training, video-based presentations, and multimedia-based training can be useful adjuncts to traditional surgical training. © Georg Thieme Verlag Stuttgart ˙ New York.

Full Text Available The purpose of this article, which can be envision as an essay, is to present a pedagogical-didactic strategy for human rights education focusing on the controversy. Advancements and setbacks faced by human rights education in Latin America are exposed in order to support this strategy. Therefore, it indicates that education has denied the conflict and explains the need for its inclusion under the idea of ‘controversial issue’. Additionally, the existence of conflicts in the interpretation, violation and/or respect for human rights is pointed out. The principal tensions that cross human rights are displayed. Based on the above, the need to support the existence of a human rights education focusing on the conflict and central components of its teaching strategy are described, and it ends by referring to its didactic approach and the role which should be assumed by faculty when teaching human rights including the conflict.

Management of Pediatric Migraine: Current Therapies.

Khrizman, Marina; Pakalnis, Ann

2018-02-01

Migraine is one of the most common neurologic conditions in pediatrics. It can be a significant stressor, causing absences from school and interruption of parents' work and family schedules. The mainstay of treatment remains educating patients about healthy lifestyle practices and the influences of sleep, stressors, and hydration on triggering migraine attacks. Psychological therapies such as biofeedback or cognitive-behavioral therapy may be beneficial in some patients, especially those with prominent psychological comorbidities. New advances in the pathophysiology of migraine and additional pediatric approval of abortive therapy with triptans have led to significant advances in the management of migraine in children. Some challenges to preventive therapy were recently noted with the negative results obtained in the Childhood and Adolescent Migraine Prevention Study, which compared prescription drugs to placebo. Inherent differences between adult and pediatric headaches, with shorter duration of pediatric migraine and prominent placebo effect, present recurring challenges for clinicians.

Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. Thieme Medical Publishers.

Gendering the migraine market: do representations of illness matter?

Science.gov (United States)

Kempner, Joanna

2006-10-01

Migraine is a common, debilitating and costly disorder. Yet help-seeking for and rates of diagnosis of migraine are low. Drawing on ethnographic observations of pharmaceutical marketing practices at professional headache conferences and a content analysis of migraine advertising, principally in the USA, this paper demonstrates: (1) that the pharmaceutical industry directs its marketing of migraine medication to women; and (2) as part of this strategy, pharmaceutical advertisements portray women as the prototypical migraine sufferer, through representations that elicit hegemonic femininity. This strategy creates the impression that migraine is a "women's disorder", which, in turn, exacerbates gender bias in help seeking and diagnosis of migraine and reifies presumptions about the epidemiology of the disorder. I conclude that these pharmaceutical marketing practices have a paradoxical effect: even as they educate and raise awareness about migraine, they also create barriers to help seeking and diagnosis.

To assess the characteristics of global experiential and didactic education offerings in the pharmacy curricula. A 2-stage web-based review of US colleges and schools of pharmacy identified country locations of international advanced pharmacy practice experiences (APPE), globally focused didactic courses, and whether these offerings were interprofessional. Schools were contacted to confirm their offerings and were asked about student participation and demand. Sixty-four percent of responding schools confirmed an international APPE offering in 67 different countries with an average graduating class participation of 6.1%. Forty-seven percent of responding schools confirmed a globally focused course offering with an average graduating class participation of 13.1%. Almost two thirds of international APPEs and a majority of courses were designated as interprofessional. Student demand did not outweigh supply for either. Colleges and schools of pharmacy in the United States are continuing to develop global education opportunities for students in the classroom and throughout the world.

Objectives To assess the impact of a program to integrate introductory pharmacy practice experiences with pharmaceutical science topics by promoting active learning, self-directed learning skills, and critical-thinking skills. Design The Learning Bridge, a curriculum program, was created to better integrate the material first-year (P1) students learned in pharmaceutical science courses into their introductory pharmacy practice experiences. Four Learning Bridge assignments required students to interact with their preceptors and answer questions relating to the pharmaceutical science material concurrently covered in their didactic courses. Assessment Surveys of students and preceptors were conducted to measure the effectiveness of the Learning Bridge process. Feedback indicated the Learning Bridge promoted students' interaction with their preceptors as well as development of active learning, self-directed learning, and critical-thinking skills. Students also indicated that the Learning Bridge assignments increased their learning, knowledge of drug information, and comprehension of relevant data in package inserts. Conclusion The Learning Bridge process integrated the didactic and experiential components of the curriculum, enhancing student learning in both areas, and offered students educational opportunities to interact more with their preceptors.

Why is migraine so common?

Science.gov (United States)

Edmeads, J

1998-08-01

Migraine is clearly a very common biological disorder, but this knowledge has not been sufficient as yet to ensure completely effective treatment strategies. There appears to be discrepancy between what migraine patients desire as the outcome of consultations and what doctors think patients want. Patients seem, from Packard's selective study (11), to want explanation and reassurance before they get pain relief, whereas doctors view pain relief as the most important aim of management. It is possible that doctors still have underlying assumptions about psychological elements of migraine which color their perceptions of their patients. Communicating the relevance of scientific progress in migraine to neurologists and PCPs is an important challenge, as is calling attention to the patient's expectations from treatment. To be effective in improving education in this area, perhaps we should first ascertain the level of knowledge about the biology and treatment of headache among general neurologists.

Prevalence of migraine in the Canadian household population.

2014-06-01

Based on data from the 2010 and 2011 Canadian Community Health Surveys and the 2011 Survey of Living with Neurological Conditions in Canada, this article provides information about migraine among people living in private households. In 2010/2011, an estimated 8.3% of Canadians (2.7 million) reported that they had been diagnosed with migraine by a health professional. Females were more likely than males to report migraine: 11.8% versus 4.7%. Migraine prevalence was highest among people in their 30s and 40s: 17.0% for women and 6.5% for men. Compared with the national figure, the prevalence of migraine was lower in Quebec (6.8%) and higher in Manitoba (9.5%), Nova Scotia (9.1%) and Ontario (8.8%). Among people who reported a migraine diagnosis, 42% took prescription medication for their condition, and 56% incurred medication-related out-of-pocket expenses. Migraine was highly comorbid with depression and affected many aspects of daily life including education, work, sleep, and driving.

The purpose of this investigation was to establish an international baseline of the quantity of physical therapist education on temporomandibular disorders (TMD) during post-professional Orthopedic Manual Physical Therapy (OMPT) education. An electronically distributed survey was sent to programs and data analyzed for trends, including a comparison of TMD and cervical spine disorders education. Current data were compared to pre-existing data from the United States. For the current data-set, the Mann-Whitney U test demonstrated statistical significance when comparing TMD and cervical spine disorders education for both the hours of didactic training provided ( p  didactic ( p  didactic ( p  = 0.23) or clinical education ( p  = 0.15) of cervical spine topics. These data again indicate a lack of uniformity between post-professional training programs in OMPT with respect to TMD education. There is, however, consistency in that most programs provided more training on cervical spine disorders than TMD. Based on these findings, further investigations are appropriate to determine if TMD education is adequate during post-professional OMPT education.

Full Text Available From the point of view of andragogical didactics as one of the basic science of andragogy, we first define basic andragogical terms. Andragogical didactics is mostly interested in the process of education of adults. The terms it focuses on are learning followed by education and fixing boundaries of the term lesson. The key question is whether education follows andragogical or pedagogical process and how are these two approaches different. The author also suggests some translations of terms form the area of andragogical didactics.

Increasing faculty participation in resident education and providing cost-effective self-assessment module credit to faculty through resident-generated didactics.

Science.gov (United States)

Kim, Hyun; Malatesta, Theresa M; Anné, Pramila R; McAna, John; Bar-Ad, Voichita; Dicker, Adam P; Den, Robert B

Board certified radiation oncologists and medical physicists are required to earn self-assessment module (SAM) continuing medical education (CME) credit, which may require travel costs or usage fees. Data indicate that faculty participation in resident teaching activities is beneficial to resident education. Our hypothesis was that providing the opportunity to earn SAM credit in resident didactics would increase faculty participation in and improve resident education. SAM applications, comprising CME certified category 1 resident didactic lectures and faculty-generated questions with respective answers, rationales, and references, were submitted to the American Board of Radiology for formal review. Surveys were distributed to assess main academic campus physician, affiliate campus physician, physicist, and radiation oncology resident impressions regarding the quality of the lectures. Survey responses were designed in Likert-scale format. Sign-test was performed with P motivation to attend resident didactics (P = .004). Residents reported an increased amount of time required to prepare lectures (P = .008). We are the first department, to our knowledge, to offer SAM credit to clinical faculty for participation in resident-generated didactics. Offering SAM credit at resident lectures is a cost-effective alternative to purchasing SAM resources, increases faculty attendance, and may improve the quality of radiation oncology resident education.

Full Text Available Introduction. Nowadays, there are not a lot of works devoted to a graphic method of logic-semantic modeling of knowledge. Meanwhile, an interest towards this method increases due to the fact of essential increase of the content of visual component in information and educational sources. The present publication is the authors’ contribution into the solution of the problem of search of new forms and means convenient for visual and logic perception of a training material, its assimilation, operating by elements of knowledge and their transformations.The aim of the research is to justify graphical implementation of the method of logic-semantic modeling of knowledge, presented by a natural language (training language and to show the possibilities of application of figurative and conceptual models in student teaching.Methodology and research methods. The research methodology is based on the specified activity-regulatory, system-multi-dimensional and structural-invariant approach and the principle of multidimensionality. The methodology the graphic realization of the logic-semantic models in learning technologies is based on didactic design using computer training programs.Results and scientific novelty. Social and anthropological-cultural adaptation bases of the method of logical-semantic knowledge modeling to the problems of didactics are established and reasoned: coordinate-invariant matrix structure is presented as the basis of logical-semantic models of figurative and conceptual nature; the possibilities of using such models as multifunctional didactic regulators – support schemes, navigation in the content of the educational material, educational activities carried out by navigators, etc., are shown. The characteristics of new teaching tools as objects of semiotics and didactic of regulators are considered; their place and role in the structure of the external and internal training curricula learning activities are pointed out

Migraine is frequently undertreated. The 4-item Migraine Assessment of Current Therapy (Migraine-ACT) questionnaire is a simple and reliable tool to identify patients requiring a change in current acute migraine treatment. To investigate the responsiveness of the Migraine-ACT tool, and compare it with that of the Migraine Disability Assessment (MIDAS) questionnaire, for patients with migraine at 1100 primary care sites in Spain. Patients eligible for this open-label, 2-visit prospective study reported migraine for >1 year and >or=1 migraine attack per month and were new to the clinic or on follow-up care for MIDAS questionnaires were administered, and patient satisfaction with treatment was recorded, at baseline and at 3 months. A total of 3272 patients, 78% female, were enrolled, and 2877 (88%) returned for the 3-month visit. Investigators changed baseline migraine treatment for 72% of returning patients; 85% and 80% of these patients had improved Migraine-ACT and MIDAS scores at 3 months, respectively. Patients who reported being completely or very satisfied with migraine treatment numbered 492 (15%) at baseline and 1406 (49%) at 3 months. Migraine-ACT and MIDAS score agreement for improvement at 3 months was poor (kappa = 0.339). Both the mean MIDAS score and the distribution of Migraine-ACT scores improved over the course of 3 months; however, Migraine-ACT scores were significantly (P MIDAS scores. The area under the curve in the receiver-operating characteristic analysis was significantly (P MIDAS (0.70) questionnaire. These results suggest that the Migraine-ACT questionnaire can be used more reliably than the MIDAS questionnaire for detecting improvements in treatment of new and follow-up patients with migraine.

Meta-Theoretical Contributions to the Constitution of a Model-Based Didactics of Science

Science.gov (United States)

Ariza, Yefrin; Lorenzano, Pablo; Adúriz-Bravo, Agustín

2016-10-01

There is nowadays consensus in the community of didactics of science (i.e. science education understood as an academic discipline) regarding the need to include the philosophy of science in didactical research, science teacher education, curriculum design, and the practice of science education in all educational levels. Some authors have identified an ever-increasing use of the concept of `theoretical model', stemming from the so-called semantic view of scientific theories. However, it can be recognised that, in didactics of science, there are over-simplified transpositions of the idea of model (and of other meta-theoretical ideas). In this sense, contemporary philosophy of science is often blurred or distorted in the science education literature. In this paper, we address the discussion around some meta-theoretical concepts that are introduced into didactics of science due to their perceived educational value. We argue for the existence of a `semantic family', and we characterise four different versions of semantic views existing within the family. In particular, we seek to contribute to establishing a model-based didactics of science mainly supported in this semantic family.

Erasmus Darwin's Deistic Dissent and Didactic Epic Poetry: Promoting Science Education to a Mixed Audience Under the Banner of Tolerance

Science.gov (United States)

Martin, Kirsten Anne

Erasmus Darwin's task as a Deistic Dissenter poet who wished to promote science education to a mixed audience was complex. There was mainstream concern over what Deists and Dissenters actually believed about God, their involvement in science, and, especially, how their published works, whatever the subject, might affect public morality and politics. I argue that Darwin's poetry is primarily in the genre of Lucretian didactic epic but that it also involves elements of other written traditions (literary and non-literary). I focus on English didactic poetry, the theological written traditions of Dissent and Deism, and a particular tradition of erotic satire. The genre of Lucretian didactic epic and the tradition of English didactic poetry are non-identical. In Darwin's Lucretian didactic epic, resemblances to such poems as Pope's Essay on Man challenge ideas about what kind of narrative a didactic poem in the English language can deliver. Techniques from the theological written traditions of Dissent and Deism reflect Darwin's affiliations, signal that science education fits within a larger debate about intellectual freedom, and promote tolerance for differences of opinion about nature. Mimicry of a particular tradition of erotic satire helps to downplay the address to a mixed audience while satirising some common misconceptions about poetry, botany, and women in the period. Darwin's poetry challenges ideas about what people from his community of belief meant to communicate or transmit by writing for the general public, what the general public was entitled to learn, and what poetry was able to teach. Perhaps Darwin's biggest modification of Lucretian didactic epic was that he did not tell his readers exactly what to think, but how.

“Why did you select that instead of something else?” - Experiential didactic knowledge, didactics and science of teaching

A growing interest in the education system has led to a stronger focus on assessment and documentation of quality in teaching and learning at all levels of the education system. An important question is where teachers locate the arguments for the selections they make in the planning and evaluation...... of teaching and learning. The aim of this paper is twofold: to introduce three types of knowledge – experiential didactic knowledge, didactics, and the science of teaching – and to demonstrate how, in different ways, they provide teachers with knowledge that can be used in selection and reasoning.

2017-06-01

To investigate the characteristics of vomiting in pediatric migraineurs and the relationship of vomiting with other migraine-related parameters. The cohort included children and adolescents with migraine attending a headache clinic of a tertiary pediatric medical center from 2010 to 2016. Patients were identified by a retrospective database search. Data were collected from medical files. The presence of vomiting was associated with background and headache-related parameters. The study group included 453 patients, 210 boys (46.4%) and 243 girls (53.6%), of mean age 11.3 ± 3.7 years. Vomiting was reported by 161 patients (35.5%). On comparison of patients with and without vomiting, vomiting was found to be significantly associated with male gender (54% vs 42.1%, P migraine onset (8.0 ± 3. years vs 9.6 ± 3.7 years, P migraine (67% vs 58.7%, P migraine (24.1% vs 10.1%, P migraine in both parents (9.3% vs 3.1%, P = .007), and migraine in either parent (57.5% vs 45.5%, P = .02). The higher rate of vomiting in the younger patients and the patients with awakening pain may be explained by a common underlying pathogenetic mechanism of vomiting and migraine involving autonomic nerve dysfunction/immaturity. The association of vomiting with parental migraine points to a genetic component of vomiting and migraine. It should be noted that some of the findings may simply reflect referral patterns in the tertiary clinic. © 2017 American Headache Society.

2015-02-01

The purpose of this investigation was to establish a baseline of physical therapist education on temporomandibular disorders (TMD)-related topics during credentialed orthopedic manual physical therapy fellowship training and compare it to cervical spine disorders education. An online survey was distributed electronically to each fellowship program credentialed by the American Physical Therapy Association (APTA) and recognized by the Academy of Orthopedic Manual Physical Therapists (AAOMPT). Data were analyzed to compare overall exposure to TMD educational content, including a direct comparison of TMD and cervical spine disorders education. The response rate was 79%. Thirteen programs (87%) reported providing both didactic and clinical training on both TMD and cervical spine disorders. Didactic education for cervical spine disorders ranged from 16-20 hours to over 25 hours, whereas TMD hours ranged from 0 to 6-10 hours. Clinical education for cervical spine disorders ranged from 11-15 hours to over 25 hours, whereas TMD hours ranged from 0 to 6-10 hours. The number of hours of exposure during didactic training and the number of patients exposed to during clinical training were significantly different when comparing TMD to cervical spine disorders exposure (P<0.0001). The data indicate a lack of uniformity between credentialed fellowship programs in orthopedic manual physical therapy with respect to the extent to which programs expose trainees to evaluation and management of TMD. There is consistency in that all programs provided more training on cervical spine disorders than TMD. Despite a high level of clinical specialization, fellows-in-training receive minimal TMD education.

Riley, Jeffrey B; Austin, Jon W; Holt, David W; Searles, Bruce E; Darling, Edward M

2004-09-01

A challenge faced by many university-based perfusion education (PE) programs is the need for student clinical rotations at hospital locations that are geographically disparate from the main educational campus. The problem has been addressed through the employment of distance-learning environments. The purpose of this educational study is to evaluate the effectiveness of this teaching model as it is applied to PE. Web-based virtual classroom (VC) environments and educational management system (EMS) software were implemented independently and as adjuncts to live, interactive Internet-based audio/video transmission from classroom to classroom in multiple university-based PE programs. These Internet environments have been used in a variety of ways including: 1) forum for communication between the university faculty, students, and preceptors at clinical sites, 2) didactic lectures from expert clinicians to students assigned to distant clinical sites, 3) small group problem-based-learning modules designed to enhance students analytical skills, and 4) conversion of traditional face-to-face lectures to asynchronous learning modules. Hypotheses and measures of student and faculty satisfaction, clinical experience, and learning outcomes are proposed, and some early student feedback was collected. For curricula that emphasize both didactic and clinical education, the use of Internet-based VC and EMS software provides significant advancements over traditional models. Recognized advantages include: 1) improved communications between the college faculty and the students and clinical preceptors, 2) enhanced access to a national network of clinical experts in specialized techniques, 3) expanded opportunity for student distant clinical rotations with continued didactic course work, and 4) improved continuity and consistency of clinical experiences between students through implementation of asynchronous learning modules. Students recognize the learning efficiency of on

Dipyridamole may induce migraine in patients with migraine without aura

Dipyridamole inhibits phosphodiesterase 5 (PDE5) and adenosine re-uptake. The most prominent side-effect is headache. We examined the migraine-generating effects of dipyridamole as well as the cerebral blood velocity response in a single-blind study, including 10 patients with migraine without aura...... repeatedly. Headache was induced in all migraine patients and in eight of 10 healthy subjects (P = 0.47) with no significant difference in headache intensity (P = 0.53).

Thus, dipyridamole induces symptoms of migraine and an initial decrease in V(mca) in migraine patients, but not significantly more than in healthy subjects. This relatively low frequency of migraine induction, compared with nitric oxide donors and sildenafil, is probably due to the less specific action...

Managerial instrument for didactic staff structure optimization for Distance Learning

Directory of Open Access Journals (Sweden)

Gavrus Cristina

2017-01-01

Full Text Available Distance learning is a modern system for providing educational services and is relatively new in Romania, if related to the date of its emergence in Europe. More and more active working people are interested in this form of education, paying of course a special attention to its quality. It is quite difficult to appraise the quality of educational programs but several instruments and criteria have been developed over time. The present paper proposes an original mathematical instrument that is aiming at human resources, this type of resources being considered extremely important in case of providing educational service. The number of teachers is crucial for a distance learning program study, because the didactic staff must cover a number of didactic classes that take place on weekends. Concretely, this paper is focused on finding an algorithm that allows the didactic staff structure optimization. For accomplishing this objective, two managerial instruments were use. One of them is mathematical linear programing technique, that develops a mathematical model for didactic staff structure and the other one is WinQSB software package that tests the mathematical model.

Full Text Available The use of cinema as didactical resource in the Mathematics classroom has interested several authors and teachers during the last years, mainly because of its power to motivate students. On this point, suggestive compilations of scenes containing mathematical references, detailed analysis of movies closely related to Mathematics and even didactical materials to be used in the classroom have been developed. This article proposes a theoretical framework for designing classroom sequences based on the didactical situation which can arise from movies or fiction series scenes. In order to develop such a framework, we follow a didactical engineering process, taking into account some specific characteristics, as the one related to the didactical transposition, as it is required to consider the mathematic knowledge within the chosen scene, overall the way it appears. As well, a classroom experience is described, designed following the mentioned guidelines and implemented in the course of a collaborative project between two secondary education centers, where a significant motivation increase has been detected, due to using mathematical situations from the real world (or from fictional contexts but which can be easily assimilated by the students. There was also evidence about the fact that the designed didactical sequences allow to reduce the cognitive gap required to acquire certain mathematical concepts, because of the scenes provide additional information within an extra-mathematical context. Therefore, our proposal establishes some basic considerations in order to efficiently design didactical sequences using movie scenes as a resource, underlining its power to motivate as well as its facilitating ability when introducing new mathematical concepts to our students.

Full Text Available Migraine is a common neurological disorder and can cause severely disabling during attacks. The highest prevalence occurs between the ages of 25 and 55 years, potentially the most productive period of life. Migraine leads to a burden not only to the individual, but also to the family and society. Prior studies have found migraine occurs with some illness at a greater than coincidental rate than is seen in the general population. These occurrences are called “comorbidity”, which means that these disorders are interrelated with migraine. To delineate migraine comorbidity is important because it can help improve treatment strategies and understand the possible pathophysiology of migraine. The comorbid illnesses in patients with migraine include stroke, sub-clinical vascular brain lesions, coronary heart disease, hypertension, patent foramen ovale, psychiatric diseases (depression, anxiety, bipolar disorder, panic disorder, and suicide, restless legs syndrome, epilepsy, and asthma. In this paper, we review the existing epidemiological and hospital based studies and illustrate the connections between these illness and migraine.

Use a presurvey of primary care providers (PCPs) enrolled in a continuing medical education (CME) program on headache management to ascertain their existing knowledge, attitudes, and beliefs regarding migraine and use a postsurvey to determine the extent to which the CME program has brought participant knowledge, attitudes, and skills closer to conformance with best evidence. Migraine is a common and debilitating condition, which PCPs may not always manage satisfactorily. In an effort to improve management, the American Headache Society has developed a CME program called BRAINSTORM that encourages PCPs to adopt the US Headache Consortium Guidelines for headache care. A 20-item questionnaire was developed that covered the essential elements of migraine care. The questionnaire was administered before and after a BRAINSTORM presentation to 254 consenting primary care clinicians attending a medical meeting at 1 of 6 sites. A control group of 112 comparable physicians who did not attend the presentation completed the same questionnaire. Prepresentation scores of attendees were compared to scores of nonattendees to assess the generalizability of results. Prepresentation scores on selected questions were used to assess participant baseline knowledge, attitudes, and beliefs. Pre- and postpresentation scores for attendees at all sites were compared using the Mantel-Haenszel statistic to assess the effectiveness of the BRAINSTORM CME. Pre- and postpresentation scores were compared by site using the Breslow-Day test to evaluate any differential impact based on CME location. Prepresentation scores of attendees and nonattendees were found to be similar. No significant difference in performance was noted across sites. A chi-square analysis revealed a statistically significant difference between pre- and postpresentation scores for 16 of the test's 20 questions. In the pretest, all participants scored 66% posttest on all except 2 questions related to prevalence, impact, and

Radiologists could improve their knowledge of contrast reaction management. The aim of this study was to evaluate to what degree the implementation of a didactic module resulted in improved technologist, nurse, and physician knowledge and comfort levels regarding the appropriate management of adverse reactions to contrast media. After institutional review board approval was obtained, nurses, technologists, and physicians involved in contrast administration were required to complete the educational module. Premodule and postmodule assessments were designed online. Each assessment included knowledge-based questions regarding the appropriate management of different types of contrast reactions, as well as questions regarding each respondent's comfort level with the treatment of various types of adverse contrast reactions. Comfort level was measured using a 6-point, Likert-type scale. Premodule and postmodule assessment scores were compared using McNemar's test. After module completion, physicians demonstrated a statistically significant improvement in knowledge regarding the proper administration route, concentration, and dose of intramuscular epinephrine. Physicians demonstrated significantly increased comfort with the administration of intramuscular epinephrine to adult and pediatric patients after module completion (P Didactic instruction in contrast reaction management results in improved knowledge and comfort levels for physicians, nurses, and technologists. However, a significant percentage of personnel still reported feeling uncomfortable treating an adverse contrast reaction after module completion, suggesting that didactic instruction alone may be inadequate.

outcomes of alternative laboratory work in secondary and tertiary physics education we decided to approach the underlying cause of the problem. Framed in the theory of Didactical Situations in mathematics we adapt the concept of the didactical contract to the physics education context to locate aspects...... of the traditional laboratory learning environment that would lead to resistance from those involved if faced with alternatives. We conclude that both teachers and students lean heavily on a type of algorithm that ensures an appearance of having successfully completed the assigned tasks. This algorithmic didactical...... contract permeates through secondary education into university physics education. Our results allow for a better renegotiation of didactical contracts and thus for avoiding typical problems related to the implementation of alternative tasks.

Full Text Available OBJECTIVE: To assess the role of odors in triggering or worsening migraine in men. METHOD: Ninety-eight male migraineurs from the general population were assessed individually through questionnaires. Environmental factors relating to their migraine were reported, with special focus on the role of odors. RESULTS: Odors were the second most frequent triggering factor for migraine attacks (48%, behind stressful situations (59%. Likewise, odors were the second most frequent worsening factor (73%, just behind excessive light (74%. Thirty-three individuals (33.4% stated that odors were both triggering and worsening factors for their migraine attacks. Perfume, cigarette smoke and cleaning products were the most frequent migraine-related odors reported by these male migraineurs. CONCLUSION: This was the first study to assess the role of odors in migraine exclusively in men. There was a high degree of odor-related migraine among these men, thus suggesting that patient education could alert such individuals to gender-related factors, since different triggering and worsening factors have been reported by males and females.

The stigma of migraine.

Full Text Available BACKGROUND: People who have a disease often experience stigma, a socially and culturally embedded process through which individuals experience stereotyping, devaluation, and discrimination. Stigma has great impact on quality of life, behavior, and life chances. We do not know whether or not migraine is stigmatizing. METHODS: We studied 123 episodic migraine patients, 123 chronic migraine patients, and 62 epilepsy patients in a clinical setting to investigate the extent to which stigma attaches to migraine, using epilepsy as a comparison. We used the stigma scale for chronic illness, a 24-item questionnaire suitable for studying chronic neurologic diseases, and various disease impact measures. RESULTS: Patients with chronic migraine had higher scores (54.0±20.2 on the stigma scale for chronic illness than either episodic migraine (41.7±14.8 or epilepsy patients (44.6±16.3 (p<0.001. Subjects with migraine reported greater inability to work than epilepsy subjects. Stigma correlated most strongly with the mental component score of the short form of the medical outcomes health survey (SF-12, then with ability to work and migraine disability score for chronic and episodic migraine and the Liverpool impact on epilepsy scale for epilepsy. Analysis of covariance showed adjusted scores for the stigma scale for chronic illness were similar for chronic migraine (49.3; 95% confidence interval, 46.2 to 52.4 and epilepsy (46.5; 95% confidence interval, 41.6 to 51.6, and lower for episodic migraine (43.7; 95% confidence interval, 40.9 to 46.6. Ability to work was the strongest predictor of stigma as measured by the stigma scale for chronic illness. CONCLUSION: In our model, adjusted stigma was similar for chronic migraine and epilepsy, which were greater than for episodic migraine. Stigma correlated most strongly with inability to work, and was greater for chronic migraine than epilepsy or episodic migraine because chronic migraine patients had less ability

Migraine is a common neurological disorder that affects 11% of adults worldwide. This disease most likely has a neurovascular origin. Migraine with aura (MA) and more common form - migraine without aura (MO) – are the two main clinical subtypes of disease. The exact pathomechanism of migraine is still unknown, but it is thought that both genetic and environmental factors are involved in this pathological process. The first genetic studies of migraine were focused on the rare subtype of MA: familial hemiplegic migraine (FHM). The genes analysed in familial and sporadic migraine are: MTHFR, KCNK18, HCRTR1, SLC6A4, STX1A, GRIA1 and GRIA3. It is possible that migraine is a multifactorial disease with polygenic influence. Recent studies have shown that the pathomechanisms of migraine involves both factors responsible for immune response and oxidative stress such as: cytokines, tyrosine metabolism, homocysteine; and factors associated with pain transmission and emotions e.g.: serotonin, hypocretin-1, calcitonin gene-related peptide, glutamate. The correlations between genetic variants of the HCRTR1 gene, the polymorphism 5-HTTLPR and hypocretin-1, and serotonin were observed. It is known that serotonin inhibits the activity of hypocretin neurons and may affect the appearance of the aura during migraine attack. The understanding of the molecular mechanisms of migraine, including genotype-phenotype correlations, may contribute to finding markers important for the diagnosis and treatment of this disease.

Application of Learning Curves for Didactic Model Evaluation: Case Studies

Directory of Open Access Journals (Sweden)

Felix Mödritscher

2013-01-01

Full Text Available The success of (online courses depends, among other factors, on the underlying didactical models which have always been evaluated with qualitative and quantitative research methods. Several new evaluation techniques have been developed and established in the last years. One of them is ‘learning curves’, which aim at measuring error rates of users when they interact with adaptive educational systems, thereby enabling the underlying models to be evaluated and improved. In this paper, we report how we have applied this new method to two case studies to show that learning curves are useful to evaluate didactical models and their implementation in educational platforms. Results show that the error rates follow a power law distribution with each additional attempt if the didactical model of an instructional unit is valid. Furthermore, the initial error rate, the slope of the curve and the goodness of fit of the curve are valid indicators for the difficulty level of a course and the quality of its didactical model. As a conclusion, the idea of applying learning curves for evaluating didactical model on the basis of usage data is considered to be valuable for supporting teachers and learning content providers in improving their online courses.

In the training of engineering personnel for the aerospace industry the integrated model of didactic communication involves the identification and description of its various components, typical modes of interaction (modes that reflect different aspects of the person's understanding of the world around him and himself in the process of different types of education and upbringing. Didactic communication in the process of training engineering personnel for the aerospace industry is a multi-level, multi-stage and multi-component phenomenon. The modes, possibilities and limitations of this communication are related to the level and direction of personal, interpersonal and professional development of interaction subjects. The productivity of preparing engineering personnel for the aerospace industry is related to the choice of a model of didactic communication, which is addressed in different ways to the development of cognitive, value-semantic and meta-cognitive structures that form one or another type of education and upbringing.

Understanding migraine and psychiatric comorbidity.

Seng, Elizabeth K; Seng, Cynthia D

2016-06-01

This article describes recent trends in our understanding of the role of psychiatric disorders in the experience and treatment of migraine, and the role of migraine in the experience and treatment of psychiatric disorders. Although the majority of studies evaluating psychiatric comorbidity in migraine have focused on depression, anxiety, and bipolar disorders are highly associated with migraine and relevant for prognosis and treatment planning. Comorbid psychiatric disorders may be associated with poorer treatment response for some acute pharmacotherapies; however, people with comorbid migraine and mood or anxiety disorders can achieve large responses to preventive pharmacologic and behavioral therapies. Emerging research is developing and evaluating behavioral treatments designed to manage cooccurring migraine and mood or anxiety disorders. Stigma related to psychiatric disorders has been well characterized, and could exacerbate extant migraine-related stigma. Anxiety and mood disorders are prevalent in people with migraine, although not ubiquitous. Psychiatric comorbidity is associated with greater migraine symptoms and disability; however, people with comorbid depression or anxiety are amenable to preventive migraine treatment. Research regarding migraine treatment strategies optimized for people with comorbid psychiatric disorders is critical to advancing care and reducing stigma for this important subpopulation of people with migraine.

Epigone migraine vertigo (EMV): a late migraine equivalent.

Pagnini, P; Vannucchi, P; Giannoni, B; Pecci, R

2014-02-01

Migrainous headache is determined by pathogenetic mechanisms that are also able to affect the peripheral and/or central vestibular system, so that vestibular symptoms may substitute and/or present with headache. We are convinced that there can be many different manifestations of vestibular disorders in migrainous patients, representing true different clinical entities due to their different characteristics and temporal relashionship with headache. Based on such considerations, we proposed a classification of vertigo and other vestibular disorders related to migraine, and believe that a particular variant of migraine-related vertigo should be introduced, namely "epigone migraine vertigo" (EMV): this could be a kind of late migraine equivalent, i.e. a kind of vertigo, migrainous in origin, starting late in the lifetime that substitutes, as an equivalent, pre-existing migraine headache. To clarify this particular clinical picture, we report three illustrative clinical cases among 28 patients collected during an observation period of 13 years (November 1991 - November 2004). For all patients, we collected complete personal clinical history. All patients underwent standard neurotological examination, looking for spontaneous-positional, gaze-evoked and caloric induced nystagmus, using an infrared video camera. We also performed a head shaking test (HST) and an head thrust test (HTT). Ocular motility was tested looking at saccades and smooth pursuit. To exclude other significant neurological pathologies, a brain magnetic resonance imaging (MRI) with gadolinium was performed. During the three months after the first visit, patients were invited to keep a diary noting frequency, intensity and duration of vertigo attacks. After that period, we suggested that they use prophylactic treatment with flunarizine (5 mg per day) and/or acetylsalicylic acid (100 mg per day), or propranolol (40 mg twice a day). All patients were again recommended to note in their diary the frequency

Full Text Available Clinical trials and electrophysiologic studies demonstrated increased perceptual sensitivity in patients suffering from migraines. At least, one triggering factor is described in 85% of migraine patients. The aim of this report was to investigate the relationship between contact lens (CL usage and migraine attacks in two cases. Two patients who were diagnosed with migraine reported that the frequency of migraine attacks increased after they switched to using CL with different base curves (BCs. These two patients, who began using CL with different BCs experienced discomfort and dryness of the eye. The ocular complaints were followed by migraine attacks. CL intolerance was also developed during migraine attack in one of the cases. The frequency of migraine attacks decreased and allodynia relieved significantly when flatter BCs were selected. CL related stimulus could have triggered the migraine attack. CLs should be well fitted in migraine patients with allodynia.

In 2016, a large meta-analysis brought the number of susceptibility loci for migraine to 38. While sub-type analysis for migraine without aura (MO) and migraine with aura (MA) found some loci showed specificity to MO, the study did not test the loci with respect to other subtypes of migraine. This study aimed to test the hypothesis that single nucleotide polymorphisms (SNPs) robustly associated with migraine are individually or collectively associated with menstrual migraine (MM). Genotyping of migraine susceptibility SNPs was conducted using the Agena MassARRAY platform on DNA samples from 235 women diagnosed with menstrual migraine as per International Classification for Headache Disorders II (ICHD-II) criteria and 140 controls. Alternative genotyping methods including restriction fragment length polymorphism, pyrosequencing and Sanger sequencing were used for validation. Statistical analysis was performed using PLINK and SPSS. Genotypes of 34 SNPs were obtained and investigated for their potential association with menstrual migraine. Of these SNPs, rs2506142 located near the neuropilin 1 gene (NRP1), was found to be significantly associated with menstrual migraine (p = 0.003). Genomic risk scores were calculated for all 34 SNPs as well as a subset of 7 SNPs that were nearing individual significance. Overall, this analysis suggested these SNPs to be weakly predictive of MM, but of no prognostic or diagnostic value. Our results suggest that NRP1 may be important in the etiology of MM. It also suggests some genetic commonality between common migraine subtypes (MA and MO) and MM. The identification of associated SNPs may be the starting point to a better understanding of how genetic factors may contribute to the menstrual migraine sub-type.

Why does sleep stop migraine?

Bigal, Marcelo E; Hargreaves, Richard J

2013-10-01

The relationship between sleep and migraine headaches is complex. Changes in sleep patterns can trigger migraine attacks, and sleep disorders may be associated with increased migraine frequency. Furthermore, migraine patients and their doctors very consistently report that sleep relieves already established migraine attacks. Herein we will try to answer the question, "Why does sleep stop migraine?" Since evidence for this relationship is largely based on empirical clinical observation, we will not provide a clinical review of the association. Instead, we will focus on the pathophysiology of migraine attacks and its intersections with sleep biology.

Basilar migraine.

Basilar migraine is a complicated headache which the International Headache Society describes as 'migraine with aura symptoms clearly originating from the brainstem or from both occipital lobes'. For years this headache was thought to originate from a transient disturbance in the vertebrobasilar circulation, but more recent studies suggest that a central neuronal disorder may be the source of migraine. Basilar migraines may have certain symptoms which are similar to other neurologic, vascular, psychiatric and metabolic diseases, yet there are specific criteria which can help differentiate it from other diagnoses. It is characterized by a throbbing occipital headache which may be preceded by an aura. The unusual symptoms of basilar migraine, which may precede and continue throughout the duration of the headache and even after it, include bilateral visual symptoms, altered mental status, vertigo, gait ataxia, bilateral paresthesia, bilateral paralysis and dysarthria. We describe a 29-year-old black female whose husband brought her to the emergency department complaining of confusion, headache, and left-sided weakness for 2 h prior to arrival.

The KATP channel in migraine pathophysiology: a novel therapeutic target for migraine.

To review the distribution and function of K ATP channels, describe the use of K ATP channels openers in clinical trials and make the case that these channels may play a role in headache and migraine. K ATP channels are widely present in the trigeminovascular system and play an important role in the regulation of tone in cerebral and meningeal arteries. Clinical trials using synthetic K ATP channel openers report headache as a prevalent-side effect in non-migraine sufferers, indicating that K ATP channel opening may cause headache, possibly due to vascular mechanisms. Whether K ATP channel openers can provoke migraine in migraine sufferers is not known. We suggest that K ATP channels may play an important role in migraine pathogenesis and could be a potential novel therapeutic anti-migraine target.

Full Text Available This article brings results of a doctoral research based in the studies of Sociodiscursive Interactionism (SDI, particularly, in its didactic aspect. Data was obtained in a field research carried out in a public school of Londrina, Paraná State, in a 6th grade class, focused in the didactic transposition of the genre ‘letter of complaint’, under the instrumentalization of the ‘genre didactic sequence’ (GDS procedure. The epistemological focus of the article concentrates on the analysis of a founder didactic gesture: ‘the internal regulation’ –implemented by the diagnostic evaluation of the students initial production. The objective is to show the accomplishment of this gesture in the development of this step of the SDG, highlighting both the result of the learning diagnostic process and the specific didactic gestures mobilized to set this stage of the learning project. It was found that the didactic approach of the diagnostic regulation mobilized after the writing of the first version of the genre, is essential for the GDS global development, since it shows the ‘errors’ that require the didactic intervention.

This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willis.

This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willis. The dependency of the posterior cerebral artery on the carotid circulation existing in 41% of the migraine accompagnee does not lead to any particular alteration of the accompanying symptoms and signs. The idea is discussed to divide the migraine syndrome into simple, focal and complicated migraine on the basis of a uniform pathogenesis.

The stress and migraine interaction.

Science.gov (United States)

Sauro, Khara M; Becker, Werner J

2009-10-01

There are several ways in which stress may interact with migraine in those predisposed to migraine attacks. These interactions may result from biochemical changes related to the physiological stress response, as, for example, the release of corticotrophin releasing hormone, or from changes induced by the psychological response to stressors. Stress is the factor listed most often by migraine sufferers as a trigger for their attacks, but in addition there is evidence that stress can help initiate migraine in those predisposed to the disorder, and may also contribute to migraine chronification. Migraine attacks themselves can act as a stressor, thereby potentially leading to a vicious circle of increasing migraine frequency. Since the important factor in the stress-migraine interaction is likely the individual's responses to stressors, rather than the stressors themselves, the acquisition of effective stress management skills has the potential to reduce the impact of stressors on those with migraine.

According to the International Headache Society, ophthalmoplegic migraine is recurrent attacks of headache with migrainous characteristics associated with paresis of one or more ocular cranial nerves (commonly the third nerve) in the absence of any demonstrable intracranial lesion. We report a patient with typical clinical features of ophthalmoplegic migraine. A 21-year-old man had right frontal throbbing headaches recurring twice a year. His headache lasted for 1 to 5 days and was followed by slight drooping of his eyelid and double vision that lasted for approximately 3 months. On examination he had ptosis and adduction paralysis of the right eye. Brain MRI revealed a thickened, enhancing right oculomotor nerve. He was treated with methylprednisolone 1000 mg/d IV for 5 days. Only 2 weeks later, clinical improvement was observed and 3 months later the oculomotor nerve enhancement resolved. Ophthalmoplegic migraine has been considered to have a microvascular, ischemic etiology, but more recently it has been reclassified as a demyelinating condition affecting the oculomotor. To our knowledge, this is the first ophthalmoplegic migraine case presented pretreatment and post-treatment with clinical photographic documentation and an MRI showing enduring thickening of the oculomotor nerve although symptoms and contrast enhancement resolved.

Migraine--more than a headache: women's experiences of living with migraine.

Rutberg, Stina; Öhrling, Kerstin

2012-01-01

In this qualitative study the aim was to explore the meaning of living with migraine. In-depth interviews were conducted with ten women about their experience of living with migraine. Halfway through the interview, the women drew a picture of what living with migraine is like, and the interview continued with the conversation being guided by the picture. The interviews were analyzed using a hermeneutic phenomenological method inspired by van Manen. The analysis revealed an essence "Being obliged to endure a life accompanied by an unpredictable and invisible disorder" and three themes "Being besieged by an attack", "Struggling in a life characterized by uncertainty" and "Living with an invisible disorder." Migraine is a debilitating disorder which accompanies life in the sense that it or the threat of its return is always present, and yet invisible to others. The struggle of enduring life with migraine is worsened by the feeling of having an invisible disorder and of being doubted. There is a need to increase the knowledge among healthcare professionals about what it means to live with migraine, something this qualitative study offers.

Full Text Available Background Migraine is a primary headache causing substantial disability in patients. The prevalence of migraine in women is still high. Menarche, menstruation, pregnancy, menopause, and the use of hormonal contraceptives and hormone replacement treatment may influence migraine occurrence. The aim of this study was to determine the major determinants of migraine in adult women aged 25-65 years. Methods A cross-sectional study of 2,747 women from the baseline study “Cohort Study of Risk Factors for Non-Communicable Diseases”. The dependent variable was migraine based on the diagnosis of health providers or symptoms. Independent variables were demographic (age, marital status, education and behavioral (smoking, diet, and stress characteristics, metabolic disorders (obesity, hypertension, dyslipidemia, and hormonal factors (contraception and hormone therapy. Data were collected through interviews (characteristics, health and hormonal status, diet, measurement (anthropometrics, blood pressure, and health examination (blood specimens, neurology. Data were analyzed by chi-square test and multiple logistic regression. Results Migraine in adult women was found in 710 cases (25.8% with symptoms of worsening with activity (15%, nausea and vomiting (13%, and photophobia/phonophobia (4.1%. The main determinant of migraine in adult women was stress with a 2.47-fold risk [95% CI = 2.07 to 2.95] as compared with no stress, after controlling for smoking, menstruation and hormonal drug consumption. Conclusion Stress is a major determinant of migraine in adult women, therefore health programs should be instituted through health promotion, prevention and education to control stress.

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

Objective To examine the influence of acute migraine medication adherence on migraine disability and acute medication satisfaction. Methods Adults with migraine completed three months of daily electronic diaries assessing headache symptoms, acute medication taken, acute medication satisfaction, and daily migraine disability. Repeated measures mixed-effects models examined the effect of initial medication type [migraine-specific medication (MSM) vs. over-the-counter analgesic (OTC) vs. an opiate/barbiturate], the severity of pain at dosing, and their interaction with daily migraine disability and satisfaction with acute medication. Results Participants (N = 337; 92.5% female; 91.1% Caucasian, non-Hispanic; 84.0% with episodic migraine) recorded 29,722 diary days. Participants took acute medication on 96.5% of 8090 migraine days. MSM was most frequently taken first (58%), followed by OTC (29.9%) and an opiate/barbiturate (12.1%). Acute medication was most frequently taken when pain was mild (41.2%), followed by moderate (37.7%) and severe pain (11.4%). Initially dosing with MSM while pain was mild was associated with the lowest daily disability [medication × pain at dosing F (4, 6336.12) = 58.73, p migraine disability and highest acute medication satisfaction.

Nutritional genomics is a growing area of research. Research has shown registered dietitian nutritionists (RDNs) have limited knowledge of genetics. Limited research is available regarding how didactic programs in dietetics (DPDs) meet the genetics knowledge requirement of the Accreditation Council for Education in Nutrition and Dietetics (ACEND®). The purpose of this study was to determine the extent to which the study of nutritional genomics is incorporated into undergraduate DPDs in response to the Academy of Nutrition and Dietetics position statement on nutritional genomics. The sample included 62 DPD directors in the U.S. Most programs (63.9%) reported the ACEND genetics knowledge requirement was being met by integrating genetic information into the current curriculum. However, 88.7% of programs reported devoting only 1-10 clock hours to genetics education. While 60.3% of directors surveyed reported they were confident in their program's ability to teach information related to genetics, only 6 directors reported having specialized training in genetics. The overall amount of clock hours devoted to genetics education is low. DPD directors, faculty, and instructors are not adequately trained to provide this education to students enrolled in DPDs. Therefore, the primary recommendation of this study is the development of a standardized curriculum for genetics education in DPDs.

Osler on migraine.

Science.gov (United States)

Boes, Christopher J

2015-03-01

William Osler's 1892 textbook The Principles and Practice of Medicine became the dominant medical text in the English-speaking world. Osler was labeled a therapeutic nihilist by some. The topic of migraine, including treatment, was succinctly covered in his text. The objectives of this study were to review Osler's thoughts on migraine, and outline his therapeutic recommendations. Preventively Osler mentioned bromides, iron, arsenic, nitroglycerin, and cannabis. Acutely he recommended coffee, chloroform, cannabis, antipyrin, antifebrin, phenacetin, caffeine citrate, nux vomica, or ergot. He thought cannabis was the most satisfactory remedy. Osler was not a therapeutic nihilist when it came to migraine, and his treatment recommendations were similar to other writers of his time. Osler did not draw upon his personal experience to contribute new knowledge about migraine. Regardless, given the popularity and clarity of his text, Osler's well-summarized migraine chapter had a great influence on practicing physicians.

Positron emission tomography (PET) is a brain imaging technique that allows in vivo studies of numerous physiological parameters. There have been few PET studies in migraine patients. Cerebral blood flow changes with no variations in brain oxygen consumption have been reported in patients with prolonged neurologic manifestations during migraine attacks. Parenteral administration of reserpine during migraine headache has been followed by a fall in the overall cerebral uptake of glucose. The small sample sizes and a number of methodologic problems complicate the interpretation of these results. Recent technical advances and the development of new PET tracers can be expected to provide further insight into the pathophysiology of migraine. Today cerebral cortex 5 HT{sub 2} serotonin receptors can be studied in migraine patients with PET.

Pediatric fellows receive little palliative care (PC) education and have few opportunities to practice communication skills. In this pilot study, we assessed (1) the relative effectiveness of simulation-based versus didactic education, (2) communication skill retention, and (3) effect on PC consultation rates. Thirty-five pediatric fellows in cardiology, critical care, hematology/oncology, and neonatology at two institutions enrolled: 17 in the intervention (simulation-based) group (single institution) and 18 in the control (didactic education) group (second institution). Intervention group participants participated in a two-day program over three months (three simulations and videotaped PC panel). Control group participants received written education designed to be similar in content and time. (1) Self-assessment questionnaires were completed at baseline, post-intervention and three months; mean between-group differences for each outcome measure were assessed. (2) External reviewers rated simulation-group encounters on nine communication domains. Within-group changes over time were assessed. (3) The simulation-based site's PC consultations were compared in the six months pre- and post-intervention. Compared to the control group, participants in the intervention group improved in self-efficacy (p = 0.003) and perceived adequacy of medical education (p < 0.001), but not knowledge (p = 0.20). Reviewers noted nonsustained improvement in four domains: relationship building (p = 0.01), opening discussion (p = 0.03), gathering information (p = 0.01), and communicating accurate information (p = 0.04). PC consultation rate increased 64%, an improvement when normalized to average daily census (p = 0.04). This simulation-based curriculum is an effective method for improving PC comfort, education, and consults. More frequent practice is likely needed to lead to sustained improvements in communication competence.

Energy Metabolism Impairment in Migraine.

Cevoli, Sabina; Favoni, Valentina; Cortelli, Pietro

2018-06-22

Migraine is a common disabling neurological disorder which is characterised by recurring headache associated with a variety of sensory and autonomic symptoms. The pathophysiology of migraine remains not entirely understood, although many mechanisms involving the central and peripheral nervous system are now becoming clear. In particular, it is widely accepted that migraine is associated with energy metabolic impairment of the brain. The purpose of this review is to present an update overview of the energy metabolism involvement in the migraine pathophysiology. Several biochemical, morphological and magnetic resonance spectroscopy studies have confirmed the presence of energy production deficiency together with an increment of energy consumption in migraine patients. An increment of energy demand over a certain threshold create metabolic and biochemical preconditions for the onset of the migraine attack. The defect of oxidative energy metabolism in migraine is generalized. It remains to be determined if the mitochondrial deficit in migraine is primary or secondary. Riboflavin and Co-Enzyme Q10, both physiologically implicated in mitochondrial respiratory chain functioning, are effective in migraine prophylaxis, supporting the hypothesis that improving brain energy metabolism may reduce the susceptibility to migraine.

Migraine is a highly prevalent and disabling neurological disorder associated with a wide range of psychiatric comorbidities. In this manuscript, we provide an overview of the link between migraine and several comorbid psychiatric disorders, including depression, anxiety and post-traumatic stress disorder. We present data on psychiatric risk factors for migraine chronification. We discuss the evidence, theories and methods, such as brain functional imaging, to explain the pathophysiological links between migraine and psychiatric disorders. Finally, we provide an overview of the treatment considerations for treating migraine with psychiatric comorbidities. In conclusion, a review of the literature demonstrates the wide variety of psychiatric comorbidities with migraine. However, more research is needed to elucidate the neurocircuitry underlying the association between migraine and the comorbid psychiatric conditions and to determine the most effective treatment for migraine with psychiatric comorbidity.

Preventive Migraine Treatment

Science.gov (United States)

Silberstein, Stephen D.

2015-01-01

Purpose of Review: This article reviews the evidence base for the preventive treatment of migraine. Recent Findings: Evidence-based guidelines for the preventive treatment of migraine have recently been published by the American Academy of Neurology (AAN) and the Canadian Headache Society (CHS), providing valuable guidance for clinicians. Strong evidence exists to support the use of metoprolol, timolol, propranolol, divalproex sodium, sodium valproate, and topiramate for migraine prevention, according to the AAN. Based on best available evidence, adverse event profile, and expert consensus, topiramate, propranolol, nadolol, metoprolol, amitriptyline, gabapentin, candesartan, Petasites (butterbur), riboflavin, coenzyme Q10, and magnesium citrate received a strong recommendation for use from the CHS. Summary: Migraine preventive drug treatments are underutilized in clinical practice. Principles of preventive treatment are important to improve compliance, minimize side effects, and improve patient outcomes. Choice of preventive treatment of migraine should be based on the presence of comorbid and coexistent illness, patient preference, reproductive potential and planning, and best available evidence.

Full Text Available Background Migraine headaches are a common problem worldwide, especially in adolescents. They are usually chronic, with frequent relapses. Therefore, any dietary risk factor for headaches has important implications on migraineurs. However, the association between migraine and diet needs to be examined further. Objective To investigate the association between diet and migraine in adolescents. Methods We conducted a cross-sectional study in August to September 2009 on 13 - 18 year old adolescents in a senior high school in Medan, North Sumatera. We included subjects diagnosed with migraine, according to the International Headache Society (IHS criteria. Ninety participants completed the questionnaire. Foods we observed for a link to migraine included milk, chocolate, ice cream, cheese, bread, instant noodles, meatballs, chili sauce, sweetener, yoghurt, pizza, and other foods and beverages. Results Of the 90 participants with migraines, there were more females (61.1% than males. There were statistically significant associations between migraine and triggering foods (P = 0.045, 95% CI 0.59 to 0.79 as well as between migraine and family history of migraine (P = 0.043, 95% CI 0.46 to 0.66. Stress (P = 0.164, menstruation (P = 0.369, and sound or light (P= 0.577 had no significant association with migraine. A wide variety of foods and beverages were implicated as migraine precipitants. The most common were chili sauce (75.8%, ice cream (71.0%, milk (67.7%, instant noodles (67.7%, chocolate (61.3%, peanuts (59.7%, cheese (54.8% and meatballs (54.8%.

Communication issues in migraine diagnosis.

Edmeads, John

2002-06-01

To examine the importance of good communication when informing the patient of the diagnosis of migraine; to review the essentials of successful communication between physician and patient on the aspect of diagnosis; to survey learning resources for physicians on communicating information to patients. This paper is based on observations made by the author of the successful interactions of numerous international "headache experts" with their patients, on a review of the medical education literature pertaining to the teaching of communication skills, and on 30 years of not always successful communication with patients. Communicating the diagnosis of migraine is an opportunity to educate and reassure the patient, to lay the foundation for rational treatment and to help establish the successful doctor-patient relationship which is essential for effective management. No matter how accurate the diagnosis, failure to communicate it effectively to the patient (and often to significant others) may impair interactions with the patient and compromise therapy. Effective communication of a diagnosis requires clarity, relevance to the patient, a positive attitude, and reinforcement through repetition, questioning and dialogue. In terms of using the diagnosis to lay a foundation for therapy, it is useful to explain the symptoms as transient physical dysfunction of normal tissues, to indicate that there are multiple mechanisms underlying the dysfunction of which only some may presently be susceptible to treatment and to stress the relevance of emotions as factors which may powerfully affect, for better or worse, the underlying disturbed physiology of migraine. Into this model can be "plugged" all the relevant therapies for migraine. This is the ideal, but every day experience in the headache consultant's office suggest that in both primary care and specialist practice, it is infrequently attained. There are scant resources other than example for physicians to learn communication of

Behavioural management of migraine

Brown, Helen; Newman, Craig; Noad, Rupert; Weatherby, Stuart

It is important to recognise that migraine is a ‘biological’ and not a ‘psychological’ entity. However, psychological factors can be involved in migraine in 4 different ways:- 1) Migraines can be triggered by psychological stressors; 2) Severe migraine can itself be a cause of significant psychological stress which can, in turn, exacerbate the problem; 3) Even if psychological stress is not significantly involved in the genesis of the headache, pain management techniques can help people cope with their pain more effectively; 4) Longitudinal data demonstrate a complex bidirectional association between mood disorders and migraine. Treatment of a co-existing mood disorder, for example with cognitive behavioural techniques, may therefore reduce the impact of migraine. It would thus appear logical to view medical and psychological approaches as potentially synergistic rather than mutually exclusive. Functional imaging indicates that cognition, emotions, and pain experiences change the way the brain processes pain inputs. This may provide a physiological rationale for psychological interventions in pain management. As most studies of psychological management of migraine have been relatively small and the approach often varies between clinicians, the magnitude of benefit, optimum method of delivery, and the length of intervention are uncertain.

Background. Disability caused by migraine may be one of the main causes of burden contributing to poor quality of life (QOL) among migraine patients. Thus, this study aimed to measure QOL among migraine sufferers in comparison with healthy controls. Methods. Female diagnosed migraine patients (n= 100) and healthy controls (n=100) completed the Malay version of the World Health Organization QOL Brief (WHOQOL-BREF) questionnaire. Only migraine patients completed the Malay version of the Migraine Disability Assessment questionnaire. Results. Females with migraines had significantly lower total WHOQOL-BREF scores (84.3) than did healthy controls (91.9, Pmigraine patients with lower total QOL scores had 1.2 times higher odds of having disability than patients with higher total QOL scores. Conclusions. The present study showed that migraine sufferers experienced significantly lower QOL than the control group from a similar population. Disability was severe and frequent and was associated with lower QOL among the migraine patients. PMID:25632394

Objective: The relationship between migraine and psychological distress has been consistently reported in cross-sectional and longitudinal studies. We hypothesised that a stable tendency to perseverative thoughts such as rumination would mediate the relationship between migraine and psychological distress. Design and Main Outcomes Measures: Self-report questionnaires measuring depressive rumination, current psychological distress and migraine symptoms in two independent European population cohorts, recruited from Budapest (N = 1139) and Manchester (N = 2004), were used. Structural regression analysis within structural equation modelling was applied to test the mediational role of brooding and reflection, the components of rumination, between migraine and psychological distress. Sex, age and lifetime depression were controlled for in the analysis. Results: Migraine predicted higher brooding and reflection scores, and brooding proved to be a mediator between migraine and psychological distress in both samples, while reflection mediated the relationship significantly only in the Budapest sample. Conclusions: Elevated psychological distress in migraine is partially attributed to ruminative response style. Further studies are needed to expand our findings to clinical samples and to examine how rumination links to the adjustment to migraine. PMID:27616579

As a complex subjective experience, pain processing may be related to functional integration among intrinsic connectivity networks of migraine patients without aura. However, few study focused on the pattern alterations in the intrinsic connectivity networks of migraine patients without aura. Thirty-one migraine patients without aura and 31 age- and education-matched healthy controls participated in this study. After identifying the default mode network, central executive network and salience network as core intrinsic connectivity networks by using independent component analysis, functional connectivity, and effective connectivity during the resting state were used to investigate the abnormalities in intrinsic connectivity network interactions. Migraine patients without aura showed decreased functional connectivity among intrinsic connectivity networks compared with healthy controls. The strength of causal influences from the right frontoinsular cortex to the right anterior cingulate cortex became weaker, and the right frontoinsular cortex to the right medial prefrontal cortex became stronger in migraine patients without aura. These changes suggested that the salience network may play a major role in the pathophysiological features of migraine patients without aura and helped us to synthesize previous findings into an aberrant network dynamical framework.

OBJECTIVE: To report migraine postdrome symptoms in patients who report nonheadache symptoms as part of their attacks. METHODS: A prospective daily electronic diary study was conducted over 3 months in 120 patients with migraine. Nonheadache symptoms before, during, and after headache were...... pain resolved. There was no relationship between medication taken for the headache and the duration of the postdrome. The severity of the migraine was not associated with the duration of the postdrome. Overall state of health scores remained low during the postdrome. CONCLUSION: Nonheadache symptoms...... in the postdrome were common and may contribute to the distress and disability in the patients studied.

Objective: To report migraine postdrome symptoms in patients who report nonheadache symptoms as part of their attacks.  Methods: A prospective daily electronic diary study was conducted over 3 months in 120 patients with migraine. Nonheadache symptoms before, during, and after headache were...... pain resolved. There was no relationship between medication taken for the headache and the duration of the postdrome. The severity of the migraine was not associated with the duration of the postdrome. Overall state of health scores remained low during the postdrome.  Conclusion: Nonheadache symptoms...... in the postdrome were common and may contribute to the distress and disability in the patients studied. Postdrome symptoms merit larger observational studies and careful recording in clinical trials of acute and preventive migraine treatments....

Objective To evaluate relationships among modifiable psychological factors and chronic migraine and severe migraine-related disability in a clinic-based sample of persons with migraine. Background Evidence evaluating relationships between modifiable psychological factors and chronic migraine and severe migraine-related disability is lacking in people with migraine presenting for routine clinical care. Methods Adults with migraine completed surveys during routinely scheduled visits to a tertiary headache center. Participants completed surveys assessing chronic migraine (meeting criteria for migraine with ≥15 headache days in the past month), severe migraine disability (Migraine Disability Assessment Scale score ≥ 21), and modifiable psychological factors [depressive symptoms (Patient Health Questionnaire-9), anxious symptoms (Generalized Anxiety Disorder-7), Pain Catastrophizing Scale and Headache Specific Locus of Control]. Logistic regression evaluated relationships between modifiable psychological factors and chronic migraine and severe migraine disability. Results Among 90 eligible participants the mean age was 45.0 (SD = 12.4); 84.8% were women. One-third (36.0%) met study criteria for chronic migraine; half of participants (51.5%) reported severe migraine-related disability. Higher depressive symptoms (OR = 1.99, 95% CI = 1,11, 3.55) and chance HSLC (OR = 1.85, 95% CI = 1.13, 1.43) were associated with chronic migraine. Higher depressive symptoms (OR = 3.54, 95%CI = 1.49, 8.41), anxiety symptoms (OR = 3.65, 95% CI = 1.65, 8.06), and pain catastrophizing (OR = 1.95, 95% CI = 1.14, 3.35), were associated with severe migraine-related disability. Conclusions Psychiatric symptoms and pain catastrophizing were strongly associated with severe migraine-related disability. Depression and chance locus of control were associated with chronic migraine. This study supports the need for longitudinal observational studies to evaluate relationships among naturalistic

Migraine is a common neurological disorder and can cause severely disabling during attacks. The highest prevalence occurs between the ages of 25 and 55 years, potentially the most productive period of life. Migraine leads to a burden not only to the individual, but also to the family and society. Prior studies have found migraine occurs with some illness at a greater than coincidental rate than is seen in the general population. These occurrences are called “comorbidity”, which me...

Migraine - Prophylactic Treatment

Full Text Available Preventive therapy in migraine constitutes an important aspect of migraine management especially in patients who are not controlled or have significant disability despite taking drugs for acute management. In spite of te recent advances in understanding of the pathophysiology of migraine, the mechanisms of action of many preventive drugs are largely unknown. Further, these provide only about 50% reduction in frequency in about 2/3rds of migraine sufferers. Hence, risk-benefit ratio must be considered while prescribing these agents. Recent efforts to undertake large-scale meta-analysis to assess the efficacy of these agents have been rewarding and consensus guidelines have evolved. Propanolol, metoprolol, amitriptyline, sodium valproate, flunarizine and lisuride have emerged as first line drugs. The role of newer anti-convulsants and botox injections in refractory cases are being investigated. Availability, co-morbidities, medical contraindications, concomitant acute therapy and costs are important determinants for choosing a particular agent. This article reviews the guidelines to be followed in choosing the prophylactic treatment options for migraine.

Migraine is a common health problem in youth that is ranked highest for disability among neurological conditions and is one of the leading reasons for school absences. Children with migraines frequently are seen by the school nurse for care, sometimes before ever being seen by another healthcare provider for evaluation and treatment. As such, school nurses have the unique opportunity to provide education and resources to children with migraines and their family. This article provides information on the Headache Action Plan Program for Youth (HAPPY), a project involving the provision of live and online migraine education and management resources to school nurses, children, families, and primary care providers in an effort to improve migraine recognition and care in the community.

Utilising the `3P-model' to Characterise the Discipline of Didactics of Science

Science.gov (United States)

Adúriz-Bravo, Agustín; Izquierdo-Aymerich, Mercè

In our research within didactics of science, we have been exploring contributions of the so called cognitive models from contemporary philosophy of science. We have used these philosophical frameworks on different levels. As an outcome, we have formulated a model of didactics of science according to which this discipline adapts and transforms theoretical contributions from different scholarly fields. In this paper, we concentrate on this description of didactics of science, which we have called the 3P-model (i.e., philosophy + psychology + pedagogy). This model of the internal functioning of the discipline may be useful to make innovations in science curriculum design and re-conceptualise the role of science teachers as professionals. We see didactics of science as a set of interrelated activities, performed by different individuals, and ranging from theoretical production to practice of science education at school. We find the concept of technoscience suitable to account for this diversity of goals. According to this concept, scientific disciplines are identified both with generation of knowledge and with active intervention on the world. Within current didactics of science, we recognise several kinds of research, having goals more or less directed to practical intervention in science education.

DIDACTIC POTENTIAL OF PUPILS UPBRINGING BY MEANS OF LITARATURE WORKS IN EDUCATIONAL INSTITUTIONS OF WESTERN UKRAINIAN DIASPORA

Full Text Available Didactic potential of upbringing pupils in educational institutions of the Diaspora by means of artistic word has been analyzed. The attention is paid to the function of art – Ukrainian literature, which promotes the formation of fully developed personality, their preparation for the conscious and active labour activity, and therefore upbringing is closely connected with life. It is cleared out that when plunging into the system of the artistic world, the pupil learns from the life of the main positive characters how to live in the society and to be useful, because textbooks and manuals on the native literature, readers in the Diaspora provide the basis for children to learn the behaviour of consciousness, and the latter, as it is known, depends on the construction of the world in themselves, that is called the worldview. It is proved that the powerful moral-educational and artistic-aesthetic potential of Ukrainian literature is being implemented in the books of Western Ukrainian Diaspora with the aim of ethnic and cultural enrichment of pupils and above all the formation of national consciousness of Ukrainian children, active choice of their values of national spirituality. It is established that the didactic potential of the upbringing of pupils by means of artistic word allows instilling love to the native language, to Ukraine, and thus it slows down the process of assimilation. On the basis of the study of the scientific-pedagogical heritage of emigration teachers-philologists, the theoretical approaches and practice of schoolchildren education by means of the word have been analyzed, the significance of their experience for the modern educational practice has been substantiated. The system of education of schoolchildren by means of the word, which has been developed over the years, is actual for the development of pedagogical science and practice.

Behavioural management of migraine

Directory of Open Access Journals (Sweden)

Helen Brown

2012-01-01

Full Text Available It is important to recognise that migraine is a ′biological′ and not a ′psychological′ entity. However, psychological factors can be involved in migraine in 4 different ways:- 1 Migraines can be triggered by psychological stressors; 2 Severe migraine can itself be a cause of significant psychological stress which can, in turn, exacerbate the problem; 3 Even if psychological stress is not significantly involved in the genesis of the headache, pain management techniques can help people cope with their pain more effectively; 4 Longitudinal data demonstrate a complex bidirectional association between mood disorders and migraine. Treatment of a co-existing mood disorder, for example with cognitive behavioural techniques, may therefore reduce the impact of migraine. It would thus appear logical to view medical and psychological approaches as potentially synergistic rather than mutually exclusive. Functional imaging indicates that cognition, emotions, and pain experiences change the way the brain processes pain inputs. This may provide a physiological rationale for psychological interventions in pain management. As most studies of psychological management of migraine have been relatively small and the approach often varies between clinicians, the magnitude of benefit, optimum method of delivery, and the length of intervention are uncertain.

Research indicates that successful migraine assessment and treatment depends on information obtained during patient and healthcare professional (HCP) discussions. However, no studies outline how migraine is actually discussed during clinical encounters. Record naturally occurring HCP-migraineur interactions, analyzing frequency and impairment assessment, and preventive treatment discussions. HCPs seeing high volumes of migraineurs were recruited for a communication study. Patients likely to discuss migraine were recruited immediately before their normally scheduled appointment and, once consented, were audio- and video-recorded without a researcher present. Separate post-visit interviews were conducted with patients and HCPs. All interactions were transcribed. Sixty patients (83% female; mean age 41.7) were analyzed. Patients were diagnosed with migraine 14 years and experienced 5 per month, on average. Transcripts were analyzed using sociolinguistic techniques such as number and type of questions asked and post-visit alignment on migraine frequency and impairment. American Migraine Prevalence and Prevention Study guidelines were utilized. Ninety-one percent of HCP-initiated, migraine-specific questions were closed-ended/short answer; assessments focused on frequency and did not focus on attention on impairment. Open-ended questions in patient post-visit interviews yielded robust impairment-related information. Post-visit, 55% of HCP-patient pairs were misaligned regarding frequency; 51% on impairment. Of the 20 (33%) patients who were preventive medication candidates, 80% did not receive it and 50% of their visits lacked discussion of prevention. Sociolinguistic analysis revealed that HCPs often used narrowly focused, closed-ended questions and were often unaware of how migraine affected patients' lives as a result. It is recommended that HCPs assess impairment using open-ended questions in combination with the ask-tell-ask technique.

Migraine – more than a headache: Women's experiences of living with migraine

Rutberg, Stina; Öhrling, Kerstin

2012-01-01

Purpose In this qualitative study the aim was to explore the meaning of living with migraine. Methods In-depth interviews were conducted with ten women about their experience of living with migraine. Halfway through the interview, the women drew a picture of what living with migraine is like, and the interview continued with the conversation being guided by the picture. The interviews were analyzed using a hermeneutic phenomenological method inspired by van Manen. Results The analysis revealed an essence “Being obliged to endure a life accompanied by an unpredictable and invisible disorder" and three themes “Being besieged by an attack” “Struggling in a life characterized by uncertainty"and “Living with an invisible disorder." Conclusions Migraine is a debilitating disorder which accompanies life in the sense that it or the threat of its return is always present, and yet invisible to others. The struggle of enduring life with migraine is worsened by the feeling of having an invisible disorder and of being doubted. There is a need to increase the knowledge among healthcare professionals about what it means to live with migraine, something this qualitative study offers. PMID:21981545

Full Text Available The science-technology and society approach (STS underlines a consideration about science and technology as social phenomena. Its educative dimension can be manifested through the incorporation of the conceptual content, the means and didactic procedures according to its essence. To promote educative sceneries in the university, that propitiate the development of the political and ethic reflexive capacities, constitute the objective of this proposal. This enriches the repertoire of the teaching resources as a new way: the educative simulation, which helps the educative influence of STS and in the education in values. In the first phase, it is argument the inescapable relation between the two pretensions: to educate in values and STS. Then, it is offered the support for the development of a didactic model with a reflexive and constructive character in the teaching-learning process. It is highlighted what to understand for constructivism in general terms and in the didactic of sciences.

2017-05-01

Vestibular migraine has been classified as a specific entity in which vestibular symptomatology is defined as part of the migrainous disorder. New and appropriate diagnostic criteria have been proposed by the Barany and International Headache Societies. The diagnosis of vestibular migraine mainly depends on the patient history. The NIVE project is a prospectic multicentric study on vestibular migraine. The aim of this project is to evaluate demographics, epidemiology, clinical manifestations of migraine and vertigo in a large cohort of Caucasian patients affected by vestibular migraine.

To investigate the epidemiology of migrainous vertigo (MV) in the general population by assessing prevalence, clinical features, comorbid conditions, quality of life, and health care utilization. We screened a representative sample of the adult population in Germany (n = 4,869) for moderate or severe dizziness/vertigo and followed up with validated neurotologic telephone interviews (n = 1,003). Diagnostic criteria for MV were as follows: 1) recurrent vestibular vertigo; 2) migraine according to the International Headache Society; 3) migrainous symptoms during at least two vertiginous attacks (migrainous headache, photophobia, phonophobia, or aura symptoms); and 4) vertigo not attributed to another disorder. In a concurrent validation study (n = 61) the interviews had a sensitivity of 84% and a specificity of 94% for vestibular vertigo and 81% and 100% for migraine. The lifetime prevalence of MV was 0.98% (95% CI 0.70 to 1.37), the 12-month prevalence 0.89% (95% CI 0.62 to 1.27). Spontaneous rotational vertigo was reported by 67% of participants with MV while 24% had positional vertigo. Twenty-four percent always experienced headaches with their vertigo. Logistic regression analysis comparing participants with MV with dizziness-free migraineurs showed an independent association with coronary heart disease but not with sex, age, migrainous aura, education, stroke, hypertension, hyperlipidemia, body mass index, or depression. Age-adjusted health-related quality of life scores (SF-8 Health Survey) were consistently lower in participants with MV compared to dizziness-free controls. Two thirds of participants with MV had consulted a doctor but only 20% of these were diagnosed with MV. Migrainous vertigo is relatively common but underdiagnosed in the general population and has considerable personal and healthcare impact.

Cognitive functioning in adolescents with migraine

Directory of Open Access Journals (Sweden)

Melissa Andréia Costa-Silva

Full Text Available Although migraine is highly prevalent in children and teenagers, it often goes undetected in these patients, resulting in underdiagnosis and inadequate treatment. Several studies have investigated cognitive changes in adults with migraine. However, there are few studies focusing on children and adolescents. Objective : To investigate cognitive performance of adolescents with migraine. Methods : Twenty-eight adolescents diagnosed with migraine and twenty-six individuals without a history of headache were recruited for the study. All participants were evaluated using standardized neuropsychological tests. Results : Adolescents with migraine had worse performance on tests evaluating short- and long-term verbal memory, attention, executive function, and speed of processing information than controls. Conclusion : Cognitive dysfunction is common in adolescents with migraine. Since the cognitive deficits found in adolescents with migraine are similar to those reported in adults with migraine, cognitive impairment seems to persist throughout life.

Analysis of the Teacher´s Educational Practice: Didactic Thinking, Interaction and Reflection

Directory of Open Access Journals (Sweden)

Benilde García Cabrero

2008-08-01

Full Text Available The educational practice of teachers is considered as a dynamic, reflexive activity that involves events that occur in the context of student–teacher interaction, but that is not limited to what has been conceived as teaching practice, that is to say, the educational processes taking place within the classroom, but related also to the pedagogical intervention that occurs before and after the interactive processes within the classroom. This paper describes a proposal that includes three dimensions to evaluate teaching practice: 1 didactic thinking and planning; 2 educational interaction in the classroom and 3 reflection upon goals attained as a result of the operationalization of the first two dimensions. These three dimensions are interdependent, so each one affects and is affected by the other two, hence the necessity to consider them in an integral way. This proposal considers that teaching improvement programs should stem from carrying out teaching evaluation in the first place, and then proceed to teachers´ training.

In this study, we aimed to investigate whether the hopelessness, anxiety and social self-esteem scores are different in two headache groups.Materials and Methods: This study was conducted with 72 migraine patients, 28 TTH patients and 50 healthy controls. Participants filled the General Information Form, Hopeless-ness Scale (HS, Spielberger Trait Anxiety Inventory (STAI-II and Social Comparison Scale (SCS. Results: There were no differences between the groups with respect to gender, age, education years, marital status and economical status. Hopelessness scores of the TTH group was higher than the migraine and control group (p=0.001. There were no statistical differences between the migraine and TTH groups with respect to STAI-II scores but TTH group scores higher in study groups (p=0.003. Control group SCS scores were higher than both patient groups with no significant differences (p=0.072.Conclusion: These findings indicate that the patients with TTH have more hopelessness than the migraine group and more anxious than the healthy control group.

Clinical and angiographic findings in migraine are briefly reviewed in relation to cerebral hemodynamic changes shown by regional cerebral blood flow (rCBF) studies. Three cases of migraine studied by the intracarotid xenon 133 method during attacks are reported. In classic migraine, with typical...... prodromal symptoms, a decrease in cerebral blood flow has been demonstrated during the aura. Occasionally, this flow decrease persists during the headache phase. In common migraine, where such prodromata are not seen, a flow decrease has not been demonstrated. During the headache phase of both types...... of migraine, rCBF has usually been found to be normal or in the high range of normal values. The high values may represent postischemic hyperemia, but are probably more frequently secondary to arousal caused by pain. Thus, during the headache phase rCBF may be subnormal, normal or high. These findings do...

In a chiropractic college that utilizes a hybrid curriculum model composed of adult-based learning strategies along with traditional lecture-based course delivery, a literature search for educational delivery methods that would integrate the affective domain and the cognitive domain of learning provided some insights into the use of problem-based learning (PBL), experiential learning theory (ELT), and the emerging use of appreciative inquiry (AI) to enhance the learning experience. The purpose of this literature review is to provide a brief overview of key components of PBL, ELT, and AI in educational methodology and to discuss how these might be used within the chiropractic curriculum to supplement traditional didactic lecture courses. A growing body of literature describes the use of PBL and ELT in educational settings across many disciplines, both at the undergraduate and graduate levels. The use of appreciative inquiry as an instructional methodology presents a new area for exploration and study in the academic environment. Educational research in the chiropractic classroom incorporating ELT and appreciative inquiry might provide some valuable insights for future curriculum development.

Patriarcheas, Kiriakos; Xenos, Michalis

Asynchronous discussion fora all the more become part of the educational process of distance education. The goal of this research is the study of the educational techniques of Brainstorming and Snowballing to their utilisation in the frame of a distance education forum, both as far as participation and creation of learning environment and also educational effectiveness are concerned. This research refers to computer teachers’ training on didactics of programming within the framework of educational micro-worlds. As it is deduced from the data analysis and the study of the messages higher participation and improvement of critical thinking are noted when Brainstorming technique is used, while fairly less time is spent and less off-topic interventions are made when Snowballing technique is used. Meanwhile, Brainstorming is found to be more advantageous than Snowballing concerning the effectiveness both in primary level (trained teachers) and in secondary level of adaptation and knowledge impartment to the students (results of their students).

Migraine is frequently undertreated, perhaps because impaired communication between patients and physicians underestimate the disability associated with migraine attacks. The purpose of this study was to evaluate the benefits of a structured migraine diary used during a prospective open-label study of triptan-naive patients in Spain for recording information on response to therapy for a pre-study migraine attack and three consecutive migraine attacks, the first and third treated with rizatriptan 10-mg wafer and the second with usual non-triptan therapy. Of 97 patients (83% women; mean age, 39 years) who completed the study, all reported moderate to severe pain, and two-thirds reported severe to total impairment during migraine attacks. At study end, 72% of patients reported that the migraine diary helped communication with their doctor about migraine, and 70% were more or much more satisfied than before the study with level of overall medical care provided by their doctor. Patients who reported the diary to be useful also reported higher overall satisfaction with medical care (p better communicate with their patients about migraine, and all reported that it enabled them to assess differences in pain intensity and disability across patients. We conclude that a structured migraine diary can be a valuable aid for improving communication between physicians and patients regarding migraine disability and treatment outcomes.

Migraine generator network and spreading depression dynamics as neuromodulation targets in episodic migraine

Science.gov (United States)

Dahlem, Markus A.

2013-12-01

Migraine is a common disabling headache disorder characterized by recurrent episodes sometimes preceded or accompanied by focal neurological symptoms called aura. The relation between two subtypes, migraine without aura (MWoA) and migraine with aura (MWA), is explored with the aim to identify targets for neuromodulation techniques. To this end, a dynamically regulated control system is schematically reduced to a network of the trigeminal nerve, which innervates the cranial circulation, an associated descending modulatory network of brainstem nuclei, and parasympathetic vasomotor efferents. This extends the idea of a migraine generator region in the brainstem to a larger network and is still simple and explicit enough to open up possibilities for mathematical modeling in the future. In this study, it is suggested that the migraine generator network (MGN) is driven and may therefore respond differently to different spatio-temporal noxious input in the migraine subtypes MWA and MWoA. The noxious input is caused by a cortical perturbation of homeostasis, known as spreading depression (SD). The MGN might even trigger SD in the first place by a failure in vasomotor control. As a consequence, migraine is considered as an inherently dynamical disease to which a linear course from upstream to downstream events would not do justice. Minimally invasive and noninvasive neuromodulation techniques are briefly reviewed and their rational is discussed in the context of the proposed mechanism.

We conducted a two-armed experiment to evaluate student satisfaction and content mastery for an introductory pediatric radiology topic, taught by either an interactive digital game or with a traditional didactic lecture. Medical students participating in a fourth-year radiology elective were invited to participate. Student cohorts were alternatively given a faculty-supervised 1h session playing a simple interactive digital Tic-tac-toe quiz module on pediatric gastrointestinal radiology or a 1h didactic introductory lecture on the same topic. Survey questions assessed the learners' perceived ability to recall the material as well as their satisfaction with the educational experience. Results of an end-of-rotation exam were reviewed to evaluate a quantitative measure of learning between groups. Survey responses were analyzed with a chi-squared test. Exam results for both groups were analyzed with a paired Student's t-test. Students in the lecture group had higher test scores compared to students in the game group (4.0/5 versus 3.6/5, P = 0.045). Students in the lecture group reported greater understanding and recall of the material than students in the game group (P digital interactive materials reported by students in the game group (P = 0.146). Our experience supported the use of a traditional lecture over a digital game module. While these results might be affected by the specific lecture and digital content in any given comparison, a digital module is not always the superior option.

Full Text Available Introduction: the article deals with the organisation of training activities in the man-made environment. Didactic engineering is seen as a methodology within which problems of didactics are solved with application of pedagogical, psychological, engineering methods. It is obvious that in order to implement the training of future engineers in a competence-based format (according to educational standard a new type of teaching system is needed, with new capacities (properties. These systems should set each student towards the development of professionally significant (key abilities, taking into account his/her psychological characteristics; ensure training on the verge of permissible difficulties (developing training, and thereby achieve rapid development of key skills, through his/her zone of “immediate development”; to diagnose the quality of possession of a competence in the academic sense. For the objectivity and reliability of assessment of the level and depth of learned knowledge it is necessary to generate this evaluation in a metric format. As a result, we created a didactic system, which combines all the listed properties and the properties of classical systems. This allowed us to construct a new generation of didactic systems. Materials and Methods: the research is based on a systematic analysis of the activity of an engineer; on models of “zones of immediate development” by L. S. Vygotsky; on “developmental education” by L. N. Zankova; on the use of pedagogical and psychological patterns as well as taxonomic methods, didactic engineering, theory of probability and mathematical statistics. Results: constructed is a model for training engineers in the metric format of competence, which envisages a rapid development of students project and constructive abilit ies based on their knowledge learned. Discussion and Conclusions: the parameters defining the probability of engineer’s success have been described; the taxonomic scale

Deepening interest in didactical problems of teaching physics can be from the beginning associated with the creation of the subject of physics, especially at secondary schools. In the 20th century it was no longer possible to ignore the rapid development of physical science and application of its results in practice. The subject of physics required the definition of its content, development of textbooks and, amongst others, new ways of teaching in comparison with the past. The interest of teachers focused mainly on increasing the clarity of explanation - the creation of experiments and teaching aids. Since 1926 Association of Mathematicians and Physicists in the first Czechoslovak Republic issued a didactic-methodological annex to the Journal of Mathematics and Physics, as a discussion in order to increase the quality of teaching. However, this action was spontaneous and subjective. In the second half of the 20th century didactics of physics became a study discipline, part of the training of future secondary school teachers and the development of scientific work in the field of Theory of teaching physics started.

Previous studies suggest that migraine might be associated with female sexual dysfunction (FSD), although this association may be complicated by overweight/obesity. To disentangle relationships of migraine and obesity with FSD, we examined: (1) FSD rates in women who had migraine and obesity with a matched sample of women with obesity who were free of migraine and (2) associations between indices of migraine severity and FSD in a larger sample of participants with migraine and overweight/obesity, controlling for important confounders. Women with migraine and obesity seeking behavioral weight loss treatment to decrease headaches (n = 37) and nonmigraine controls (n = 37) with obesity seeking weight loss via bariatric surgery were matched on age (±5 years), body mass index (BMI; ±3 kg/m 2 ), and reported sexual activity during the past month. Both groups completed the Female Sexual Function Index (FSFI), with a validated FSFI-total cutoff score used to define FSD. In participants with migraine and overweight/obesity (n = 105), separate logistic regression models evaluated associations of migraine attack frequency, intensity, and duration with odds of having FSD, controlling for age, BMI, depression, and anxiety. On average, participants and matched controls had severe obesity (BMI = 42.4 ± 3.8 kg/m 2 ; range = 35-49.9) and were 37.3 ± 7.2 years of age (range = 22-50). FSD rate did not differ between migraine participants and controls (56.8% vs. 54.1%, P = .82). In the larger sample of participants with migraine and overweight/obesity (38.2 ± 7.8 years of age; BMI = 34.8 ± 6.4 [range = 25-50 kg/m 2 ]; 8.0 ± 4.3 migraine days/month, maximum pain intensity = 5.9 ± 1.4 on 0-10 scale; average attack duration = 18.3 ± 9.7 hours), FSD was not associated with attack frequency (P = .31), pain intensity (P = .92), or attack duration (P = .35) but was associated with more severe anxiety

The strikingly higher prevalence of migraine in females compared with males is one of the hallmarks of migraine. A large global body of evidence exists on the sex differences in the prevalence of migraine with female to male ratios ranging from 2:1 to 3:1 and peaking in midlife. Some data are available on sex differences in associated symptoms, headache-related disability and impairment, and healthcare resource utilization in migraine. Few data are available on corresponding sex differences in probable migraine (PM) and other severe headache (ie, nonmigraine-spectrum severe headache). Gaining a clear understanding of sex differences in a range of severe headache disorders may help differentiate the range of headache types. Herein, we compare sexes on prevalence and a range of clinical variables for migraine, PM, and other severe headache in a large sample from the US population. This study analyzed data from the 2004 American Migraine Prevalence and Prevention Study. Total and demographic-stratified sex-specific, prevalence estimates of headache subtypes (migraine, PM, and other severe headache) are reported. Log-binomial models are used to calculate sex-specific adjusted prevalence ratios and 95% confidence intervals for each across demographic strata. A smoothed sex prevalence ratio (female to male) figure is presented for migraine and PM. One hundred sixty-two thousand seven hundred fifty-six individuals aged 12 and older responded to the 2004 American Migraine Prevalence and Prevention Study survey (64.9% response rate). Twenty-eight thousand two hundred sixty-one (17.4%) reported "severe headache" in the preceding year (23.5% of females and 10.6% of males), 11.8% met International Classification of Headache Disorders-2 criteria for migraine (17.3% of females and 5.7% of males), 4.6% met criteria for PM (5.3% of females and 3.9% of males), and 1.0% were categorized with other severe headache (0.9% of females and 1.0% of males). Sex differences were observed in

As Sweden changes toward a multicultural society, scientific knowledge of transcultural nursing care becomes increasingly important. Earlier studies in Swedish nursing education have demonstrated a lack of knowledge base in transcultural nursing. Through an extensive review of the literature, a didactic model was developed to help facilitate the establishment of this body of knowledge in transcultural nursing. The article demonstrates how the model applies the content and structure of Leininger's theory of culture care diversity and universality and ethnonursing method in a 3-year nursing program in theory as well as clinical education. The model includes a written guide for faculty members, with references to scientific articles and documents to be used.

Unilateral nasal pain with migraine features.

Migraine attacks exclusively felt in the face are very rare, the pain involving the territories supplied by the second and third branches of the trigeminal nerve. Two patients suffering from heminasal pain attacks accompanied with typical migrainous features and responsive to oral or intranasal triptans - but not to intranasal lidocaine or oxymetazoline. In one patient, the attacks could be precipitated upon slight touching on the tip of the nose, in the other attacks were preceded by the nasal sensation typically heralding sneezing. Migraine pain mostly develops within the innervation territory of the first branch of the trigeminal nerve, which includes the nose. Therefore, episodes of unilateral nasal pain with migrainous features could be considered a migraine with unusual topography (nasal migraine). Painful nasal attacks occasionally preceded by stimulation of trigeminal afferents in the nose, could be conceived of as migraine-tic syndrome.

Neurotrophins and Migraine.

Martins, L B; Teixeira, A L; Domingues, R B

2017-01-01

Neurotrophins (NTs) have been implicated in generation and modulation of nociceptive pathways. Change in NTs levels is associated with painful conditions and neurological diseases such as migraine. Currently, it is generally recognized that migraine headaches result from the activation and sensitization of trigeminal sensory afferent fibers leading to neuropeptides release such as calcitonin gene-related peptide (CGRP) and substance P (SP). This triggers an inflammatory cascade causing a neurogenic inflammation. The agents responsible for trigeminal activation and release of neuropeptides are still unclear. It is known that the transient receptor potential vanilloid receptor-1 (TRPV1) is an important mediator of CGRP and SP release. TRPV1 is closely associated with tyrosine receptors kinases (Trk), which are NTs receptors. NTs can act on TRPV1 increasing its sensitivity to painful stimuli, therefore predisposing to hyperalgesia. Upregulation of ion channels and pain receptors in dorsal root ganglion neurons may be alternative mechanisms by which NTs contribute to pain development. Only a few studies have been performed to investigate the role of NTs in migraine. These studies have reported changes in NTs levels in migraine patients either during the migraine attack or in free-headache periods. © 2017 Elsevier Inc. All rights reserved.

The social educator as manager of self- managed communities towards a didactics of group work

Full Text Available This paper seeks to reflect upon the function of social educators as promoters of self-managing communities as well as to outline the didactic contribution which group work techniques provide for this task. Therefore, the competencies that a social educator should have been addressed from a trace concept of “community” and its relationship whit social education as a non formal process; principally insisting on its role as “leader” of the self-management community processes: how far Leadership should go and where it should stop. It can be concluded that the social educator is required to work among groups of human beings with the main purpose of arousing the collective processes of teaching and learning of knowledge, attitudes and strategies. These strategies lead communities to manage the environment in which they live in an autonomous way so that decent living conditions are guaranteed for everyone. 

Bipolar Affective Disorder and Migraine

Birk Engmann

2012-01-01

Full Text Available This paper consists of a case history and an overview of the relationship, aetiology, and treatment of comorbid bipolar disorder migraine patients. A MEDLINE literature search was used. Terms for the search were bipolar disorder bipolar depression, mania, migraine, mood stabilizer. Bipolar disorder and migraine cooccur at a relatively high rate. Bipolar II patients seem to have a higher risk of comorbid migraine than bipolar I patients have. The literature on the common roots of migraine and bipolar disorder, including both genetic and neuropathological approaches, is broadly discussed. Moreover, bipolar disorder and migraine are often combined with a variety of other affective disorders, and, furthermore, behavioural factors also play a role in the origin and course of the diseases. Approach to treatment options is also difficult. Several papers point out possible remedies, for example, valproate, topiramate, which acts on both diseases, but no first-choice treatments have been agreed upon yet.

Positron emission tomography and migraine

International Nuclear Information System (INIS)

Chabriat, H.

1992-01-01

Positron emission tomography (PET) is a brain imaging technique that allows in vivo studies of numerous physiological parameters. There have been few PET studies in migraine patients. Cerebral blood flow changes with no variations in brain oxygen consumption have been reported in patients with prolonged neurologic manifestations during migraine attacks. Parenteral administration of reserpine during migraine headache has been followed by a fall in the overall cerebral uptake of glucose. The small sample sizes and a number of methodologic problems complicate the interpretation of these results. Recent technical advances and the development of new PET tracers can be expected to provide further insight into the pathophysiology of migraine. Today cerebral cortex 5 HT 2 serotonin receptors can be studied in migraine patients with PET

Full Text Available The goal of this review is to explore the literature reports of acute confusional migraine (ACM including patient characteristics, migraine symptomatology, and proposed diagnostic criteria. A literature review was conducted using PubMed, Scopus and Web of Science using the terms “confusional migraine” and “confusional state in migraine”. All the relevant articles from 1970 to 2016 were included. A total of 120 patients were found in the literature. Most of the cases were seen in the pediatric population with a slight male predominance. Personal or family history of migraine was common. Most patients had a headache prior to the confusional state. In addition to confusion and agitation, some developed visual (32.5% and/or sensory symptoms (19% and/or speech problems (39% either prior to or during the confusional state. Data on treatment outcomes is lacking. Patients with most common forms of migraine report attention and cognitive disturbances but awareness remains intact as opposed to patients with ACM. ACM is a distinct entity and should be included as part of the appendix of International Classification of Headache Disoders-3 beta version (ICHD-3β criteria. Prospective studies are needed to further study this disorder and its association with other migraine forms.

Misselling as a New Topic of Financial Education? A Didactic Analysis of Investment Advise after the Financial Crisis

Directory of Open Access Journals (Sweden)

Dirk Loerwald

2010-07-01

Full Text Available Personal financial investments are, as a matter of course, a topic of economic education because they are a life situation which is inherently economical. In contrast, faulty advising in banks which has become focussed upon due to the extent it has played a part in the recent financial crisis is mentioned neither in curricula nor in educational text books. Numerous private funds have been exposed as unprofitable investments. One reason for this problem is to be found in the marketing staff of the banks who did not invest their customer’s funds securely enough – and the customers did not notice it. What conclusions can be drawn from this for general financial education after the financial crisis? The economic education has failed to address the topic of “faulty advising in banks” as well. On the basis of categorical economic didactics the following contribution will analyse whether one has an exemplary case here upon which students can win generalized, transferable insights. In this context, the topic of personal financial investments will be classified in an efficient manner and the risk of opportunism in advising situations will be analysed with the help of the positive principal-agent theory. The results of this analysis of informational asymmetries within financial markets give direction to the development and revision of curricula in the didactics of economic education. With the following article a sustainable theoretical fundament will be created to underscore the obligatory inclusion of this topic in curricula as well as its realisation for target groups in school text books.

Curriculum and course redesign are expected and intentional efforts in health professions education. For physician assistant (PA) education, ongoing program self-assessment is a required accreditation standard and may guide deliberate changes within curriculum. The purpose of this article is to describe one PA program’s approach to the redesign of 4 courses into 3 courses that span the entire didactic phase. Significant lessons learned include the importance of planning ahead, identifying key players, documenting the process as part of ongoing self-assessment, competency mapping, and being prepared to make real-time modifications and changes based on course evaluations and faculty feedback. Our approach and guiding principles to the successful redesign of the didactic courses may provide both established and new PA educational programs with useful methods to apply in their own unique curricula.

Migraine & paediatric obesity: a plausible link?

Directory of Open Access Journals (Sweden)

Sarit Ravid

2014-01-01

Full Text Available Obesity and migraine are both highly prevalent disorders in the general population, influenced by genetic and environmental risk factors. In recent studies, obesity was found to be a strong risk factor for transformed migraine and, among migraineurs, obesity was associated with frequent headaches and higher disability scores. Suggested mechanisms included: (i obesity as a pro-inflammatory state may be associated with neurovascular inflammation in patients with migraine; (ii elevated levels of plasma calcitonin gene-related peptide (CGRP in obese individuals may play a role as an important post-synaptic mediator of trigeminovascular inflammation in migraine; (iii dismodulation in the hypothalamic neuropeptide, orexin, in obese persons may be associated with increased susceptibility to neurogenic inflammation causing migraine attacks; and (iv leptin and adiponectin can activate proinflammatory cytokine release that is involved in the pathogenesis of migraine. In addition, both conditions are associated with psychiatric co-morbidities, such as depression and anxiety, that can further increase headache frequency and disability. Therefore, the effect of obesity on migraine outcome is important. Weight and BMI should be measured and calculated in all children presenting with migraine, and weight control should be a part of the treatment.

Functional Imaging and Migraine: New Connections?

Schwedt, Todd J.; Chong, Catherine D.

2015-01-01

Purpose of Review Over the last several years, a growing number of brain functional imaging studies have provided insights into mechanisms underlying migraine. This manuscript reviews the recent migraine functional neuroimaging literature and provides recommendations for future studies that will help fill knowledge gaps. Recent Findings Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) studies have identified brain regions that might be responsible for mediating the onset of a migraine attack and those associated with migraine symptoms. Enhanced activation of brain regions that facilitate processing of sensory stimuli suggests a mechanism by which migraineurs are hypersensitive to visual, olfactory, and cutaneous stimuli. Resting state functional connectivity MRI studies have identified numerous brain regions and functional networks with atypical functional connectivity in migraineurs, suggesting that migraine is associated with aberrant brain functional organization. Summary fMRI and PET studies that have identified brain regions and brain networks that are atypical in migraine have helped to describe the neurofunctional basis for migraine symptoms. Future studies should compare functional imaging findings in migraine to other headache and pain disorders and should explore the utility of functional imaging data as biomarkers for diagnostic and treatment purposes.

Goble, J

1990-12-01

The terms psychodrama, sociodrama, and didactic psychodrama are defined. These three action techniques are compared with respect to their differing goals and methodologies. The application of the use of didactic psychodrama and sociodrama with student nurses undergoing Psychiatric Nurse Training is outlined, together with verbal reports elicited from the students following, a) a 20-week study day programme where didactic psychodrama was used on an regular basis, and b) a sociodrama workshop. It is concluded that sociodrama and didactic psychodrama are powerful action learning methods that can be successfully employed with junior student psychiatric nurses. It is also acknowledged that the underlying rationale, and procedural details of these two methods differ from, those associated with more conventional social skills based training approaches, and these differences have implications for trainers.

To evaluate the association between osmophobia and the characteristics of patients and their headaches, among migraine patients. This was a cross-sectional study. Patients who consecutively sought medical attendance in a primary care unit were asked about their headaches over the last 12 months. Those who had migraine were included. A semi-structured interview, the Headache Impact Test and the Hospital Anxiety and Depression Scale were used. 147 patients had migraine; 78 had osmophobia; 60 had significant anxiety symptoms; and 78 had significant depression symptoms. The mean age of these patients was 43.2 years (± 13.7); 91.2% were women. The mean length of time with complaints of headache was 13.8 years (± 12). Among the migraine patients, those with anxiety, more years of headache history, and phonophobia presented significantly more osmophobia (multivariate logistic regression). Osmophobia in migraine patients is associated with significant anxiety symptoms, length of headache history, and phonophobia. © 2015 American Academy of Pain Medicine. All rights reserved.

Full Text Available This study intends to offer a different vision of the concept of prenatal pedagogy, deeply linked to children’s sanitary need. We will try to find out its importance in the university scope through students’ opinions and the analysis of the didactic program of Early Childhood Education Degree.In order to achieve this, we have set ourselves the general objective of gathering information from university students of the Early Education Degree about the importance of training in prenatal education for their future work as teachers, considering that they are the most involved in the education of children in their early stages. Furthermore, we intend to reckon the relevance given to this content by the University of Huelva, one of the educational institutions responsible for teacher training.The data were collected through questionnaires applied to a sample of 58 3rd-4th level students of Early Childhood Education at the University of Huelva. This instrument was selected for the suitability of its application collectively. Moreover, an analysis of the didactic programs of the courses of this degree was carried out to verify the existence of contents of prenatal pedagogy within them.From this research it is derived that certain notions of prenatal pedagogy are essential to become future nursery teachers, thus providing a greater amount of resources when facing our students’ learning process.In conclusion, we checked that the university students surveyed believe that it is necessary to have notions of prenatal pedagogy so as to become efficient teachers. The lack of this notion in the didactic programs represents a formative gap that will have negative repercussions on their initial formation and, consequently, on their educational practice. Therefore, the educational institutions in charge of the preparation of new teachers should consider including prenatal pedagogy within their didactic programs.

The Relationship between Migraine and Nutrition

Full Text Available Migraine is a kind of headache accompanied by neurologic, gastrointestinal, and autonomous variations. The roles of factors that trigger migraine, especially nutrition triggers, have become much more questionable with the increase in the rate of migraine occurrence. Some patients with migraine have stated that their headache attacks start without any reason. However, inner triggers such as hormonal changes or external triggers such as air exchange, some smells or the association of both triggers can start the headache. Each patient may not have same sensitivity to these triggers. A single factor might become prominent in some patients, but more than one factor may need to be required in other patients. Although the connection between migraine and the factors such as stress, environmental factors, chronic diseases, and nutritional and sleep status has been known, their mechanisms are still not clear. Nutritional status and the effects of nutrition play an important role being pain triggers in everybody, especially children and young people who suffer from migraine headache. Considering the migraine triggers generally, it has been suggested in studies that there is at least one nutrition-related trigger and hunger is the most frequently reported trigger in terms of diet. Moreover it is known that chocolate, tea, coffee, cheese, and alcohol may trigger migraine because of some specific elements within them. In recently conducted studies, using some functional foods have raised on the treatment of migraine. For this reason, the relationship between migraine and triggering factors as food and nutrition are examined in this study.

2017-01-01

BACKGROUND: To review the distribution and function of KATP channels, describe the use of KATP channels openers in clinical trials and make the case that these channels may play a role in headache and migraine. DISCUSSION: KATP channels are widely present in the trigeminovascular system and play...... an important role in the regulation of tone in cerebral and meningeal arteries. Clinical trials using synthetic KATP channel openers report headache as a prevalent-side effect in non-migraine sufferers, indicating that KATP channel opening may cause headache, possibly due to vascular mechanisms. Whether KATP...... channel openers can provoke migraine in migraine sufferers is not known. CONCLUSION: We suggest that KATP channels may play an important role in migraine pathogenesis and could be a potential novel therapeutic anti-migraine target....

The typical migraine patient is exposed to a myriad of migraine triggers on a daily basis. These triggers potentially can act at various sites within the cerebral vasculature and the central nervous system to promote the development of migraine headache. The challenge to the physician is in the identification and avoidance of migraine trigger factors within patients suffering from migraine headache. Only through a rational approach to migraine trigger factors can physicians develop an appropriate treatment strategy for migraine patients.

Prevalence of bruxism in children with episodic migraine - a case–control study with polysomnography

Science.gov (United States)

2014-01-01

Background Parents of children with migraine have described a higher prevalence of sleep bruxism and other sleep disturbances in their children. The objective of this study was to use polysomnography to investigate the prevalence of bruxism during sleep in children with episodic migraine relative to controls. Findings Controls and patients were matched by sex, age, years of formal education, presence of snoring, arousals per hour, and respiratory events per hour. A total of 20 controls, between 6 and 12 years old, with no history of headache, recruited from public schools in Sao Paulo between 2009 and 2012, and 20 patients with episodic migraine recruited from the Headache Clinic at the Federal University of Sao Paulo between 2009 and 2012 underwent polysomnography. No intervention was performed before sleep studies. Among migraine patients, 27.5% experienced aura prior to migraine onset. The sleep efficiency, sleep latency, REM sleep latency, arousals per hour, percentage of sleep stages, and breathing events per hour were similar between groups. Five children (25%) with episodic migraine exhibited bruxism during the sleep study while this finding was not observed in any control (p = 0.045). Conclusions Our data demonstrate that bruxism during sleep is more prevalent in children with episodic migraine. Further prospective studies will help elucidate the underlying shared pathogenesis between bruxism and episodic migraine in children. PMID:24886343

Association Between Obesity and Migraine in Women.

Pavlovic, Jelena M; Vieira, Julio R; Lipton, Richard B; Bond, Dale S

Migraine is a common and highly disabling condition that is particularly prevalent among women and especially women of reproductive age. The tremendous rise in adiposity in the Western world has led to an epidemic of obesity in women. The particular effects of obesity on women with migraine of various ages are the focus of this review. Conflicting findings from various studies with different approaches and populations have made challenging definitive conclusions about associations between migraine and obesity. While the association between obesity and migraine frequency has been consistently demonstrated and obesity is considered a risk factor for progression from episodic to chronic migraine, the association between obesity and migraine prevalence is still somewhat debated and appears to be dependent on gender and age, with the most consistent effects observed in women younger than 55 years of age. Association between migraine and obesity is most commonly observed in women of reproductive age. The multimodal changes associated with age and hormonal change in women likely play a role in this relationship, as obesity does not appear to be related to migraine in women over 55 years of age. Future studies focusing on the migraine-obesity relationship in women should examine the effects of age, endogenous hormonal state, and exogenous hormones on migraine and obesity.

Sleep in Patients with Chronic Migraine.

Yang, Chun-Pai; Wang, Shuu-Jiun

2017-09-01

The biological and pathophysiological interaction between sleep and chronic migraine (CM) remains to be fully elucidated. In this article, we provide a narrative review of the literature on sleep disturbance and CM, highlighting recent advances in sleep research and insights into mechanisms that could mediate a role of sleep disturbances in migraine chronification. We discuss the potential for cognitive-behavioral insomnia therapy (CBTi) as an intervention for CM with comorbid insomnia. Finally, we propose a model of the mechanisms underlying the interactions among sleep physiology, maladaptive migraine-coping behaviors, and coexisting factors which contribute to sleep disturbances in CM based on conceptual models used in sleep research. Insomnia is the most common sleep complaint among patients with CM. CM patients experience more frequent and severe insomnia symptoms than patients with episodic migraine (EM). It has been suggested that sleep disturbances may predispose individuals to migraine attacks, which may affect the pain-processing trigeminovascular system and thus play a role in migraine progression. Encouraging but limited evidence suggests that management of insomnia via behavioral sleep therapy may reverse CM to EM and possibly prevent migraine chronification. Migraine has a complex relationship with sleep. The use of objective sleep study such as polysomnographic microstructural sleep analysis and actigraphy could help connect sleep disturbances and processes related to CM. Future longitudinal studies should examine whether effective behavioral treatments such as CBTi can reverse migraine chronification.

Migraine Management During Menstruation and Menopause.

MacGregor, E Anne

2015-08-01

Migraine is most prevalent in women during their reproductive years. An understanding of the effects of menstruation and menopause on migraine can enable neurologists to provide targeted and appropriate medical and hormonal strategies, enabling their patients to achieve better control of migraine and reduced disability. This article reviews the effects of hormonal events on migraine and summarizes the evidence-based options available for management. Estrogen "withdrawal" during the late luteal phase of the natural menstrual cycle and the hormone-free interval of combined hormonal contraceptives has long been implicated in the pathophysiology of menstrual migraine. However, more recent research suggests that other independent mechanisms may be relevant. Prostaglandin inhibitors used for management of dysmenorrhea are effective for associated menstrual migraine, suggesting a common pathophysiology. The interplay between serotonin and estrogen also deserves further research. Menstrual and perimenopausal migraine can be managed effectively using a variety of strategies, the choice of which depends on the efficacy of acute treatment, predictability and regularity of menstruation, use of contraception, and presence of menstrual disorders or perimenopausal vasomotor symptoms.

Migraine accompagnee: Clinical and neutroradiological findings

International Nuclear Information System (INIS)

Schaefer, E.M.

1981-01-01

This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willisi. The dependency of the posterior cerebral artery on the carotid circulation existing in 41% of the migraine accompagnee does not lead to any particular alteration of the accompanying symptoms and signs. The idea is discussed to divide the migraine syndrome into simple, focal and complicated migraine on the basis of a uniform pathogenesis. (orig./MG) [de

The growing availability of electronic health data provides an opportunity to ascertain diagnosis-specific cases via systematic methods for sample recruitment for clinical research and health services evaluation. We developed and implemented a migraine probability algorithm (MPA) to identify migraine from electronic health records (EHR) in an integrated health plan. We identified all migraine outpatient diagnoses and all migraine-specific prescriptions for a five-year period (April 2008-March 2013) from the Kaiser Permanente, Northern California (KPNC) EHR. We developed and evaluated the MPA in two independent samples, and derived prevalence estimates of medically-ascertained migraine in KPNC by age, sex, and race. The period prevalence of medically-ascertained migraine among KPNC adults during April 2008-March 2013 was 10.3% (women: 15.5%, men: 4.5%). Estimates peaked with age in women but remained flat for men. Prevalence among Asians was half that of whites. We demonstrate the feasibility of an EHR-based algorithm to identify cases of diagnosed migraine and determine that prevalence patterns by our methods yield results comparable to aggregate estimates of treated migraine based on direct interviews in population-based samples. This inexpensive, easily applied EHR-based algorithm provides a new opportunity for monitoring changes in migraine prevalence and identifying potential participants for research studies. © International Headache Society 2015.

Migraine, cerebrovascular disease and the metabolic syndrome

Directory of Open Access Journals (Sweden)

Alexandra J Sinclair

2012-01-01

Full Text Available Evidence is emerging that migraine is not solely a headache disorder. Observations that ischemic stroke could occur in the setting of a migraine attack, and that migraine headaches could be precipitated by cerebral ischemia, initially highlighted a possibly association between migraine and cerebrovascular disease. More recently, large population-based studies that have demonstrated that migraineurs are at increased risk of stroke outside the setting of a migraine attack have prompted the concept that migraine and cerebrovascular disease are comorbid conditions. Explanations for this association are numerous and widely debated, particularly as the comorbid association does not appear to be confined to the cerebral circulation as cardiovascular and peripheral vascular disease also appear to be comorbid with migraine. A growing body of evidence has also suggested that migraineurs are more likely to be obese, hypertensive, hyperlipidemic and have impaired insulin sensitivity, all features of the metabolic syndrome. The comorbid association between migraine and cerebrovascular disease may consequently be explained by migraineurs having the metabolic syndrome and consequently being at increased risk of cerebrovascular disease. This review will summarise the salient evidence suggesting a comorbid association between migraine, cerebrovascular disease and the metabolic syndrome.

Migraine is a very prevalent disease with great individual disability and socioeconomic burden. Despite intensive research effort in recent years, the etiopathogenesis of the disease remains to be elucidated. Recently, much importance has been given to mechanisms underlying the cortical excitability that has been suggested to be dysfunctional in migraine. In recent years, noninvasive brain stimulation techniques based on magnetic fields (transcranial magnetic stimulation, TMS) and on direct electrical currents (transcranial direct current stimulation, tDCS) have been shown to be safe and effective tools to explore the issue of cortical excitability, activation, and plasticity in migraine. Moreover, TMS, repetitive TMS (rTMS), and tDCS, thanks to their ability to interfere with and/or modulate cortical activity inducing plastic, persistent effects, have been also explored as potential therapeutic approaches, opening an interesting perspective for noninvasive neurostimulation for both symptomatic and preventive treatment of migraine and other types of headache. In this chapter we critically review evidence regarding the role of noninvasive brain stimulation in the pathophysiology and treatment of migraine, delineating the advantages and limits of these techniques together with potential development and future application. © 2013 Elsevier B.V.

There is evidence that substantial weight loss through bariatric surgery (BS) may result in short-term improvement of migraine severity. However, it still remains to be seen whether smaller amounts of weight loss have a similar effect on migraine headache. This study has been designed to compare the effects of weight reduction through BS and non-surgical modifications. Migraine characteristics were assessed at 1 month before (T0), 1 month (T1), and 6 months (T2) after BS (vertical sleeve gastrectomy (VSG) (n = 25) or behavioral therapy (BT) (n = 26) in obese women (aged 18-60 years) with migraine headache. Migraine was diagnosed using the International Classification of Headache Disorders (ICHDIIβ) criteria. There was significant reduction in the visual analog scale (VAS) from the baseline to T1 and T2 in both groups. The number of migraine-free days showed a significant increase within each group (p migraine characteristics, age, changes in weight, BMI, body fat, and fat-free mass from T0 to T2, the BS group showed statistically significant lower VAS and duration of migraine attacks and a significantly higher number of migraine-free days than the BT group at T1 and T2 (p ≤ 0.028). Our results indicated that far before significant weight reduction after BS (VSG), there was marked alleviation in the severity and duration of migraine and a significant increase in the number of migraine-free days in obese female migraineurs. However, the effects in the BT group were not comparable with the effects in the BS group.

Refractory migraine surgery developed since 2003 has excellent results over the past 10 years. According to the pioneer of migraine surgery, Dr. Bahman Guyuron, 5 major surgical classifications of migraines are described in the field of plastic surgery, namely, frontal migraine, temporal migraine, rhinogenic migraine, occipital migraine, and auriculotemporal migraine. In this study, we present the preliminary surgical results of the occipital migraine surgery. A total of 22 patients with simple occipital migraines came to our outpatient clinic for help from June 2014 to February 2015. Thirteen cases were excluded owing to ineligibility for operation or other reasons. The patients who concurrently experienced other types of migraines were precluded even if they received combined migraine surgery. Therefore, 9 simple occipital migraine cases were enrolled in this study. Migraine severity was evaluated by uniform questionnaires to identify the source of migraine. Neurolysis was performed under general anesthesia, with the patient in a prone position. Postoperative conditions were evaluated at the second, fourth, sixth, and eighth weeks by posttreatment questionnaires. Of all the 9 patients, 5 experienced single-sided migraines of greater occipital nerve origin (2 left-sided and 3 right-sided cases). Two patients had bilateral migraines of greater occipital nerve origin, and unilateral right lesser occipital nerve origin was noted in one patient. The last patient had right-sided migraines of greater and lesser occipital nerve origin. As a result in the follow-up, a response rate greater than 90% was documented, and complete resolution was observed in 2 patients. Drug doses were reduced more than 50% in the remaining patients. The overall efficacy of occipital migraine surgery in this study was 88.8% (8/9 cases). Some patients with migraine are good candidates for surgical resolution with appropriate and meticulous selection. Similar to what is observed in Western

Full Text Available Abstract Background Synesthesia is, as visual migraine aura, a common and fascinating perceptual phenomenon. Here we present a unique case with synesthesias exclusively during visual migraine auras. Case presentation A 40-year-old woman with a cyclic mood disorder had suffered from migraine with visual aura for several years. On several occasions she had experienced "mixing of senses" during the aura phase. Staring at strong bright light she could experience intense taste of lemon with flow from the salivary glands. Conclusion Acquired synesthesia, exclusively coincident with migraine aura, gives support to the idea of an anomalous cortical processing underlying the phenomenon.

Methods:  The present study was of cross sectional and correlational studies. The measures included  Headache Disability Inventory and Young Early Maladaptive Schemas Questionnaire (Short Form. The  population of the study was Tehran adult patients with migraine and tension headache aged 18 to 55  years. The final study sample included 69 participants with migraine or tension headaches and 86 non- clinical samples of both genders. After referring by psychiatrists, they were selected by convenient and  targeted sampling. The two groups were matched based on sex and education. Results: Migraine and tension headache sufferers and non-clinical participants were significantly  different in 9 schemas including Emotional deprivation, Abandonment/instability, Mistrust/abuse, Social  isolation/alienation, Failure to achieve, Enmeshment/Undeveloped Self, Subjugation, Self-sacrifice and  Emotional inhibition. In addition, a series of EMSs could significantly predict 61 percent of the total  change in position of tension headaches or migraine group correctly. Discussion: It seems that EMSs are important factors influencing migraine and tension headaches. The  recognition and manipulation of these schemas along with other medical therapies can result in reducing  the symptoms of the disorder.

To describe practice behavior and understanding among pharmacy personnel, both pharmacists and non-pharmacist staff, in the management of mild and moderate migraines. Migraine is recognized as a prevalent and chronic neurological disorder. In developing countries, such as Thailand, community pharmacies are a widely used source of health care for various illnesses including migraine. However, the quality of migraine management and knowledge among pharmacy personnel is unclear. Cross-sectional study. The sample comprised 142 randomly selected community pharmacies in a city in the south of Thailand. Simulated clients visited the pharmacies twice, at least 1 month apart, to ask for the treatment of mild and moderate migraines. After the encounters, question asking, drug dispensing, and advice giving by pharmacy staff were recorded. Subsequently, the providers in 135 pharmacies participated in the interview to evaluate their knowledge in migraine management. The majority of pharmacy personnel were less likely to ask questions in cases of mild migraine when compared with moderate attack (mean score [full score = 12] 1.8 ± 1.6 vs 2.6 ± 1.5, respectively, P knowledge on migraine management. Pharmacists had better knowledge on question asking (mild migraine 5.1 ± 2.1 vs 3.1 ± 1.3, respectively, P knowledge on advice giving but poorer drug dispensing in moderate migraine according to the guidelines, relative to non-pharmacists (20.5% vs 40.3%, P = .014). A large number of community pharmacists and non-pharmacist staff had inappropriate practice behavior and understanding. Continuing education and interventions are important to improve the practice and knowledge of pharmacy personnel, particularly the pharmacists. © 2013 American Headache Society.

Full Text Available Abstract Background Migraine is a significant health problem, especially for the young people, due to its frequency and accompanying morbidity, causing disability and loss of performance. In this study, our aim was to determine the prevalence of migraine headaches among university students in Edirne, a Turkish city. Methods In this cross-sectional and descriptive study, study population was composed of students registered to Trakya University in the academic year of 2008-2009. Out of these, 3694 of them accepted to participate. Participants who had two or more headaches in the last 3 months formed the headache group. Afterwards, two preliminary questions were applied to the headache group and participants with at least one affirmative response were asked to perform the validated ID-Migraine™ test. Results The mean age of 3694 students participated in the study was 19.23 ± 1.84 (17-39 years, with adolescents:adult ratio being 2.5:1. 1613 students (43.7% did have at least two headaches in the last three months. Migraine-type headache was detected in 266 subjects (7.2% based on the ID-Migraine™ test. Of the migraine group, 72 were male (27.1% and 194 were female (72.9%. There was no significant difference in migraine prevalence between adolescent and adult age groups. Conclusions With a prevalence similar to adults, primary care physicians should be aware of the probability of migraine headaches in university students in order to maintain a successful school performance.

The aim of this study was to examine the prevalence of household food insecurity in individuals reporting migraine within a large population-based sample of Canadians. The Canadian Community Health Survey (CCHS) uses a stratified cluster sample design to obtain information on Canadians ≥12 years of age. Data on household food insecurity were assessed for individuals who reported having migraine or not, providing a current point prevalence. This was assessed for stability in two CCHS datasets from four and eight years earlier. Factors associated with food insecurity among those reporting migraine were examined and a logistic regression model of food insecurity was developed. We also examined whether food insecurity was associated with other reported chronic health conditions. Of 48,645 eligible survey respondents, 4614 reported having migraine (weighted point prevalence 10.2%). Food insecurity was reported by 14.8% who reported migraine compared with 6.8% of those not reporting migraine, giving an odds ratio of 2.4 (95% confidence interval 2.0-2.8%). This risk estimate was stable over the previous eight years. The higher risk for food insecurity was not unique to migraine and was seen with some, but not all, chronic health conditions reported in the CCHS. Food insecurity is more frequent among individuals reporting migraine in Canada. © International Headache Society 2015.

Full Text Available Background: Migraine is a common disorder which has psychiatric sequelae. Objective: The objective of this study was to determine the clinical pattern and psychiatric comorbidity of migraine. Materials and Methods: 100 cases of migraine seen over a period of one year were analysed to know the sociodemographic characteristics, clinical pattern and psychiatric morbidity. Results: Maximum patients were between 31-40 years of age group (40%, females (78.0%, married (76% and housewives (56.0%. Family history of migraine was present in 12% cases. Average age of onset was 22 years. Unilateral and throbbing type of headache was most common. The commonest frequency was one to two per week. Migraine without aura was commonest sub-type (80%. Generalized anxiety disorder (F41.1 was the most common psychiatric disorder (34%, followed by mixed anxiety and depressive disorder (F41.2 (18% and depressive episode (F32 (14%. In 22% cases, no psychiatric disorder could be elicited. Conclusion: The present study confirms that majority patients with migraine had psychiatric disorders. This needs timely detection and appropriate intervention to treat and control the migraine effectively.

The superficial temporal artery has been thought to be the main focus of pain during migraine attacks, but its diameter has never been measured directly. The use of a new, high-resolution ultrasound machine to measure arterial size in 25 migraine patients with unilateral head pain showed...... that the lumen was wider on the painful than on the non-painful side during a migraine attack. The diameters of both radial arteries and the temporal artery on the non-painful side were smaller during than between attacks. The generalised vasoconstriction was not shared by the temporal artery on the affected...... side, which suggests a local vasodilatory response. The findings suggest that cephalic arteries may play a role in migraine pathogenesis....

Migraine, vertigo and migrainous vertigo: Links between vestibular and pain mechanisms.

Science.gov (United States)

Balaban, Carey D

2011-01-01

This review develops the hypothesis that co-morbid balance disorders and migraine can be understood as additive effects of processing afferent vestibular and pain information in pre-parabrachial and pre-thalamic pathways, that have consequences on cortical mechanisms influencing perception, interoception and affect. There are remarkable parallel neurochemical phenotypes for inner ear and trigeminal ganglion cells and these afferent channels appear to converge in shared central pathways for vestibular and nociceptive information processing. These pathways share expression of receptors targeted by anti-migraine drugs. New evidence is also presented regarding the distribution of serotonin receptors in the planum semilunatum of the primate cristae ampullaris, which may indicate involvement of inner ear ionic homeostatic mechanisms in audiovestibular symptoms that can accompany migraine.

We analyzed whether migraine is associated with cognitive performance among participants of the Brazilian Longitudinal Study of Adult Health, ELSA-Brasil. Methods Cross-sectional analysis, including participants with complete information about migraine and aura at baseline. Headache status (no headaches, non-migraine headaches, migraine without aura and migraine with aura), based on the International Headache Society classification, was used as the dependent variable in the multilinear regression models, using the category "no headache" as reference. Cognitive performance was measured with the Consortium to Establish a Registry for Alzheimer's Disease word list memory test (CERAD-WLMT), the semantic fluency test (SFT), and the Trail Making Test version B (TMTB). Z-scores for each cognitive test and a composite global score were created and analyzed as dependent variables. Multivariate models were adjusted for age, gender, education, race, coronary heart disease, heart failure, hypertension, diabetes, dyslipidemia, body mass index, smoking, alcohol use, physical activity, depression, and anxiety. In women, the models were further adjusted for hormone replacement therapy. Results We analyzed 4208 participants. Of these, 19% presented migraine without aura and 10.3% presented migraine with aura. All migraine headaches were associated with poor cognitive performance (linear coefficient β; 95% CI) at TMTB -0.083 (-0.160; -0.008) and poorer global z-score -0.077 (-0.152; -0.002). Also, migraine without aura was associated with poor cognitive performance at TMTB -0.084 (-0.160, -0.008 and global z-score -0.077 (-0.152; -0.002). Conclusion In participants of the ELSA-study, all migraine headaches and migraine without aura were significantly and independently associated with poorer cognitive performance.

Determining the most effective approach for students' successful academic performance and achievement on the national licensure examination for RNs is important to nursing education and practice. A quasi-experimental design was used to compare didactic instruction and test-enhanced learning among nursing students divided into two fundamental nursing review courses in their final semester. Students in each course were subdivided into low-, intermediate-, and high-score groups based on their first examination scores. Mixed model of repeated measure and two-way analysis of variance were applied to evaluate students' academic results and both teaching approaches. Intermediate-scoring students' performances improved more through didactic instruction, whereas low-scoring students' performances improved more through test-enhanced learning. Each method had differing effects on individual subgroups within the different performance level groups of their classes, which points to the importance of considering both the didactic and test-enhanced learning approaches.

Migraine headache is a primary neurologic disease affecting millions of people worldwide. As a consequence, quality of life is diminished, productivity suffers (through loss of work force), and treatment costs are substantial. The occurrence rate in the general population is quite high, with women accounting for 3 of every 4 cases. Between January 2011 and May 2012, a total of 221 patients received hair transplants. Another 590 patients underwent hair transplantation between June 2012 and December 2016. Initially (first interval), patients were not questioned on migraine headaches in preoperative visits, but questioning was regularly done thereafter. Overall, 150 patients given transplants in the first period were surveyed by phone regarding preoperative migraine headaches. Aside from the 1 incidental discovery, no other instances of migraine emerged. Headache origins were occipital-frontal in 2 patients, occipital-temporal in 2 patients, and occipital-temporal-frontal in the 2 others. Donor/receiver areas in hair transplantation and migraine trigger zones shared locations. Headache frequencies ranged from 4 to 8 days per month (average, 6 days), and pain scores were 5-8 (10 being highest). Duration of pain was 3-5 hours (average, 4 hours). All six patients had used various medications, such as triptans, ergot, and nonsteroidal anti-inflammatory drugs, before hair transplantation. The 1 female patient was a 32-year-old seeking treatment for alopecia, with a 6-year history of migraine headaches. The male patients presenting with androgenetic alopecia (grade 4-5 by Norwood classification) had 6- to 20-year migrainous histories. After hair transplantation, each migraine sufferer was checked once in the first month and then once every 3 months. Those who could not appear in person after the first year were evaluated by phone every 3 months. Migraine headaches had ceased in all 6 patients, none of whom used medical treatments for migraines thereafter. The postoperative

Magnetic resonance spectroscopy studies in migraine

The authors describe the method of [sup 31]phosphorus magnetic resonance spectroscopy and review the results when it is applied to the study of brain and muscle energy metabolism in migraine subjects. Brain energy metabolism appears to be abnormal in all major subtypes of migraine when measured both during and between attacks. Impaired energy metabolism is also documented in skeletal muscle. It is suggested that migraine is associated with a generalized disorder of mitochondrial oxidative phosphorylation and that this may constitute a threshold for the triggering of migraine attacks. 47 refs., 10 figs., 3 tabs.

Full Text Available Several authors have pointed out that Didactic Book still plays an important role in the teaching and learning process, and is often the main, and the only educational resource available to teachers. In this way, we will analyze human body representations in Didactic Books of science adopted by a municipal public school in the city of Uruguaiana/RS. In the context of writing, we understand that body's perceptions permeate a historical and cultural construction, constituted from the relationships lived by the subjects in society. This study is a qualitative research, based on the content analysis of Bardin, in which we seek to identify human body representations in the messages, characteristics, structures, contents, and figures present in books. For this, we set up an analytical matrix with guiding questions related to the approach of the body, showed in didactic books. The results demonstrate that the contents follow the same pattern, that is, a body divided into parts like a human body just formed by limbs, organs, and tissues. They present a detailed division of content, from the cellular organization, concepts, structures, and the images are presented in a fragmented way, always following normative standards. We found these books dedicate spaces to analyze and discuss the biosocial body, in a well-elaborated way, contemplating different visions, such as sexuality beyond human reproduction. We believe that these issues should be part of the Political Education Projects (PPPs of schools and the educational system as a whole because in this way more projects will be carried out contemplating the issue. However, it is still up to the teacher to take this approach, and if such issues are not addressed in the LD, he should keep in mind that if we are thinking beings, our body is much more than organic components, and so seek means to carry out this approach.

Selectivity in Genetic Association with Sub-classified Migraine in Women

Migraine can be sub-classified not only according to presence of migraine aura (MA) or absence of migraine aura (MO), but also by additional features accompanying migraine attacks, e.g. photophobia, phonophobia, nausea, etc. all of which are formally recognized by the International Classification of Headache Disorders. It remains unclear how aura status and the other migraine features may be related to underlying migraine pathophysiology. Recent genome-wide association studies (GWAS) have identified 12 independent loci at which single nucleotide polymorphisms (SNPs) are associated with migraine. Using a likelihood framework, we explored the selective association of these SNPs with migraine, sub-classified according to aura status and the other features in a large population-based cohort of women including 3,003 active migraineurs and 18,108 free of migraine. Five loci met stringent significance for association with migraine, among which four were selective for sub-classified migraine, including rs11172113 (LRP1) for MO. The number of loci associated with migraine increased to 11 at suggestive significance thresholds, including five additional selective associations for MO but none for MA. No two SNPs showed similar patterns of selective association with migraine characteristics. At one extreme, SNPs rs6790925 (near TGFBR2) and rs2274316 (MEF2D) were not associated with migraine overall, MA, or MO but were selective for migraine sub-classified by the presence of one or more of the additional migraine features. In contrast, SNP rs7577262 (TRPM8) was associated with migraine overall and showed little or no selectivity for any of the migraine characteristics. The results emphasize the multivalent nature of migraine pathophysiology and suggest that a complete understanding of the genetic influence on migraine may benefit from analyses that stratify migraine according to both aura status and the additional diagnostic features used for clinical characterization of

Migraine is a neurological disorder that afflicts many people in the world and can cause severe disability during the attacks. The pathophysiology of migraine is complex and not fully understood. It seems that migraine is common in idiopathic intracranial hypertension (IIH). However, the association between migraine headache and IIH is still unclear. The present study was conducted to assess the prevalence of migraine headache and associated factors in IIH patients. In this cross-sectional study, a total of 68 patients diagnosed with IIH underwent a medical history interview and a neurological examination. The diagnosis of migraine was based on the four diagnostic criteria of the International Classification of Headache Disorders 3rd edition. Forty-five patients (63.2%) met the diagnostic criteria of migraine headache. There was no significant difference between patients with and without migraine headache in respect of their age, gender, body mass. This study revealed high prevalence of migraine headache in IIH patients; appropriate treatment can reduce their headache and prevent unnecessary treatments for IIH.

Neurophysiology of visual aura in migraine

International Nuclear Information System (INIS)

Shibata, Koichi

2007-01-01

Visual processing in migraine has been targeted because the visual symptoms that are commonly associated with attack, either in the form of aura or other more subtle symptoms, indicate that the visual pathways are involved in migrainous pathophysiology. The visual aura of the migraine attack has been explained by the cortical spreading depression (CSD) of Leao, neuroelectric event beginning in the occipital cortex and propagating into contiguous brain region. Clinical observations suggest that hyperexcitability occurs not only during the attack, typically in the form of photophobia, but also between attacks. Numerous human neuroimaging, neurophysiological and psychophysical studies have identified differences in cortical visual processing in migraine. The possibility of imaging the typical visual aura with BOLD functional MRI has revealed multiple neurovascular events in the occipital cortex within a single attack that closely resemble CSD. As transient synchronized neuronal excitation precedes CSD, changes in cortical excitability underlie the migraine attack. Independent evidence for altered neuronal excitability in migraineurs between attacks emerges from visual evoked potentials (VEPs) and transcranial magnetic stimulation (TMS), recordings of cortical potentials and psychophysics. Recently, both TMS and psychophysical studies measuring visual performance in migraineurs have used measures which presumably measure primary visual (V1) and visual association cortex. Our VEP and blink reflex study showed that migraine patients exhibiting allodynia might show central sensitization of braistem trigeminal neuron and had contrast modulation dysfunction during the cortical visual processing of V1 and visual association cortex in-between attacks. In pathophysiology of migraine, these neurophysiological and psychophysical studies indicate that abnormal visual and trigeminal hyperexcitability might persist between migraine attacks.

The purpose of this research is to develop the didactical design of senior high school chemistry learning based on sharing and jumping tasks in shift equilibrium chemistry. Sharing tasks used to facilitate students slow learners with help by other students of fast learners so they engage in learning. While jumping tasks used to challenge fast learners students so they didn’t feel bored in learning. In developing the didactic design, teacher activity is not only to focus on students and learning materials but also on the relationship between students and learning materials. The results of the analysis teaching plan of shift equilibrium chemistry in attached Senior High School to Indonesia University of Education showed that the learning activities more focus on how the teacher teaches instead of how the process of students’ learning. The use of research method is didactical design research (DDR). Didactical design consisted of three steps i.e. (a) analysing didactical condition before learning, (b) analyzing metapedadidactical, and (c) analyzing retrospective. Data were collected by test, observations, interviews, documentation and recordings (audio and video).The result showed that the didactical design on shift equilibrium chemistry was valid.

Managing migraine by patient profile: role of frovatriptan.

Science.gov (United States)

Cady, Roger K; Farmer, Kathleen

2016-01-01

For the last quarter of a century, triptans have been available for acute treatment of migraine but with little guidance on which of the different triptan products to use for which patient or which attack of migraine. In this article, we propose a structured approach to analysis of individual migraine attacks and patient characteristics as a means of defining and optimizing acute intervention. Assessment of patient and attack profiles includes the "5-Ps": pattern, phenotype, patient, pharmacology, and precipitants. Attending to these five components of information can assist in developing an individualized behavioral, pharmacological, and nonpharmacological comprehensive treatment plan for most migraine patients. This clinical approach is then focused on frovatriptan because of its unique molecular signature and potential novel clinical applications. Frovatriptan like all triptans is indicated for acute treatment of migraine but its role has been explored in management of several unique migraine phenotypes. Frovatriptan has the longest half-life of any triptan and consequently is often promoted for acute treatment of migraine of longer duration. It has also been studied as a short-term preventive treatment in women with menstrual-related migraine. Given that 60% of female migraineurs suffer from menstrual-related migraine, this population is the obvious group for continued study. Small studies have also explored frovatriptan's use in treating migraine predicted by premonitory symptoms as a preventive for the headache phase of migraine. By identifying patient and attack profiles, clinicians may effectively determine the viability of frovatriptan as an effective pharmacological intervention for migraine.

Didactic models in the discourse of science teachers

Full Text Available This paper presents the results of research carried out among Science Teachers at Municipal Schools in Goiânia, State of Goiás. In 2000, questionnaires were sent out to all the teachers, of whom 56 (43% replied. Through an analysis of these questionnaires, an identification of the didactic models underlying their ideas on teaching/learning was made in the hope of delineating the profile of municipal science teaching which has been going through a process of curriculum re-structuring at primary school level, since 1998, with the implementation of formation cycles. Results show that teachers are going through a period of conception change which is probably a result of the experience of living through this process of curriculum restructuring. The profile is characterized as an eclectic didactic model, combining shades of different models identified in the literature: traditional, technological, spontaneous-activist and school research models; however, closer to the spontaneous model. The inclusion of certain presuppositions from other didactic models could further indicate a period of evolution in the professional development of Science teachers, which may constitute a significant space for reflection on the aims of education and on day-by-day classroom practices.

A strong association has been established between migraine and depression. However, this is the first study to differentiate in a large sample of migraine patients for symptom dimensions of the affective disorder spectrum. Migraine patients (n=3174) from the LUMINA (Leiden University Medical Centre Migraine Neuro-analysis Program) study and patients with current psychopathology (n=1129), past psychopathology (n=477), and healthy controls (n=561) from the NESDA (Netherlands Study of Depression and Anxiety) study, were compared for three symptom dimensions of depression and anxiety. The dimensions -lack of positive affect (depression specific); negative affect (nonspecific); and somatic arousal (anxiety specific)- were assessed by a shortened adaptation of the Mood and Anxiety Symptom Questionnaire (MASQ-D30). Within the migraine group, the association with migraine specific determinants was established. Multivariate regression analyses were conducted. Migraine patients differed significantly (pmigraine patients were predominantly similar to the past psychopathology group. For the somatic arousal dimension, migraine patients scores were more comparable with the current psychopathology group. Migraine specific determinants for high scores on all dimensions were high frequency of attacks and cutaneous allodynia during attacks. This study shows that affective symptoms in migraine patients are especially associated with the somatic arousal component. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background With time, episodes of migraine headache afflict patients with increased frequency, longer duration and more intense pain. While episodic migraine may be defined as 1-14 attacks per month, there are no clear-cut phases defined, and those patients with low frequency may progress to high frequency episodic migraine and the latter may progress into chronic daily headache (> 15 attacks per month. The pathophysiology of this progression is completely unknown. Attempting to unravel this phenomenon, we used high field (human brain imaging to compare functional responses, functional connectivity and brain morphology in patients whose migraine episodes did not progress (LF to a matched (gender, age, age of onset and type of medication group of patients whose migraine episodes progressed (HF. Results In comparison to LF patients, responses to pain in HF patients were significantly lower in the caudate, putamen and pallidum. Paradoxically, associated with these lower responses in HF patients, gray matter volume of the right and left caudate nuclei were significantly larger than in the LF patients. Functional connectivity analysis revealed additional differences between the two groups in regard to response to pain. Conclusions Supported by current understanding of basal ganglia role in pain processing, the findings suggest a significant role of the basal ganglia in the pathophysiology of the episodic migraine.

The pathophysiology of migraine: implications for clinical management.

Charles, Andrew

2018-02-01

The understanding of migraine pathophysiology is advancing rapidly. Improved characterisation and diagnosis of its clinical features have led to the view of migraine as a complex, variable disorder of nervous system function rather than simply a vascular headache. Recent studies have provided important new insights into its genetic causes, anatomical and physiological features, and pharmacological mechanisms. The identification of new migraine-associated genes, the visualisation of brain regions that are activated at the earliest stages of a migraine attack, a greater appreciation of the potential role of the cervical nerves, and the recognition of the crucial role for neuropeptides are among the advances that have led to novel targets for migraine therapy. Future management of migraine will have the capacity to tailor treatments based on the distinct mechanisms of migraine that affect individual patients. Copyright © 2018 Elsevier Ltd.

Objective: To test whether level of perceived stress and reductions in levels of perceived stress (i.e., “let-down”) are associated with the onset of migraine attacks in persons with migraine. Methods: Patients with migraine from a tertiary headache center were invited to participate in a 3-month electronic diary study. Participants entered data daily regarding migraine attack experience, subjective stress ratings, and other data. Stress was assessed using 2 measures: the Perceived Stress Scale and the Self-Reported Stress Scale. Logit-normal, random-effects models were used to estimate the odds ratio for migraine occurrence as a function of level of stress over several time frames. Results: Of 22 enrolled participants, 17 (median age 43.8 years) completed >30 days of diaries, yielding 2,011 diary entries including 110 eligible migraine attacks (median 5 attacks per person). Level of stress was not generally associated with migraine occurrence. However, decline in stress from one evening diary to the next was associated with increased migraine onset over the subsequent 6, 12, and 18 hours, with odds ratios ranging from 1.5 to 1.9 (all p values < 0.05) for the Perceived Stress Scale. Decline in stress was associated with migraine onset after controlling for level of stress for all time points. Findings were similar using the Self-Reported Stress Scale. Conclusions: Reduction in stress from one day to the next is associated with migraine onset the next day. Decline in stress may be a marker for an impending migraine attack and may create opportunities for preemptive pharmacologic or behavioral interventions. PMID:24670889

The purpose of this study was to identify factors that contribute to migraine headache surgery failure and success. A retrospective chart review was conducted of patients who underwent surgery for migraine headaches performed by the senior author (B.G.) and had at least 11 months of follow-up. The study population included three groups: migraine surgery success, improvement, and failure. Thirty-six unique data points were collected for each patient. A total of 169 patients met inclusion criteria. Of these, 66 patients comprised the migraine surgery success group (S, complete elimination of migraine headaches); 67 comprised the migraine surgery improvement group (I, >50 percent reduction in migraine frequency, intensity, or duration); and 36 comprised the migraine surgery failure group (F, I, p=0.02), migraine frequency (SI, p=0.003; S>F, p=0.04), history of head or neck injury (SI, p=0.02), increased intraoperative bleeding (SF, p=0.0006; I>F, p=0.0004), site II (S>F, p=0.015), single operative site (SI, p=0.05; S>F, p=0.04). Factors associated with migraine surgery failure include increased intraoperative bleeding and surgery on fewer trigger sites. Factors associated with migraine surgery success are older age of migraine onset, higher rate of visual symptoms versus improvement group, surgery at site I or II, and deactivating all four operative sites.

The implementation of unfolding scenario-based case studies in the didactic classroom is associated with learner-centered education. The utilization of learner-centered pedagogies, such as case studies, removes the focus from the instructor and instead places it on the student. Learner-centered pedagogies are believed to improve students' levels of cognition. The purpose of this study was to examine how nurse educators are implementing the pedagogies of case studies in their undergraduate didactic courses. The goal was to examine, document, report, and, ultimately, implement the strategies. Purposeful sampling was utilized in this qualitative, multisite-designed study. For each of the four participants, three separate site visits were completed. Observations and post-observational interviews took place at each site visit. Transcribed data from interviews, observations, and course documents were imported into the computer program Nvivo8. Repetitive comparative analysis was utilized to complete the data coding process. The guiding research question of this study sought to investigate the implementation strategies of case studies in didactic nursing courses. The implementation of case studies by the participants reflected two primary patterns: Formal Implementation (FI) and Informal Implementation (II) of case studies. The FI of case studies was further divided into two subcategories: Formal Implementation of case studies used Inside the Classroom setting (FIIC) and Formal Implementation of cases studies used Outside of the Classroom (FIOC). Results of this investigation have led to an increased understanding of implementation strategies of unfolding scenario-based case studies in undergraduate nursing didactic courses. Data collected were rich in the description of specific methodologies for utilization of case studies and may serve as a resource for faculty in development of creative strategies to enhance the didactic classroom experience.

The German philosopher Immanuel Kant (1724-1804) suffered, since his forties, from a migraine with aura which showed a significant exacerbation in his seventies, coinciding with the onset of symptoms of a senile dementia of Alzheimer's type. Recorded symptoms of Kant's migraine include recurrent scintillating scotomas, one episode of diplopia, two episodes of complete amaurosis and frequent headaches described as oppressions of the head. The said symptoms of Kant's migraine can be traced not only in his letters and in accounts of his contemporary biographers, but also in the philosopher's published work.

Japan has four seasons and many chances of low atmospheric pressure or approaches of typhoon, therefore it has been empirically known that the fluctuation of weather induces migraine in people. Generally, its mechanism has been interpreted as follows: physical loading, attributed by atmospheric pressure to human bodies, compresses or dilates human blood vessels, which leads to abnormality in blood flow and induces migraine. We report our examination of the stage in which migraine tends to be induced focusing on the variation of atmospheric pressure. Subjects were 34 patients with migraine, who were treated in our hospital. The patients included 31 females and three males, whose mean age was 32 ± 6.7. 22 patients had migraine with aura and 12 patients had migraine without aura. All of patients with migraine maintained a headache diary to record atmospheric pressures when they developed a migraine. The standard atmospheric pressure was defined as 1013 hPa, and with this value as the criterion, we investigated slight fluctuations in the atmospheric pressure when they developed a migraine. It was found that the atmospheric pressure when the patients developed a migraine was within 1003-1007 hPa in the approach of low atmospheric pressure and that the patients developed a migraine when the atmospheric pressure decreased by 6-10 hPa, slightly less than the standard atmospheric pressure. Small decreases of 6-10 hPa relative to the standard atmospheric pressure of 1013 hPa induced migraine attacks most frequently in patients with migraine.

Full Text Available Migraine is a disabling neurologic condition with a spontaneous clinical evolution into a chronic form. Migraine progression from an episodic into a chronic form is realized through a period of time involving several months or years, during which an increase attack frequency occurs. .According to the International Classification of Headache Disorders (ICHD-3 chronic migraine is a type of primary headache occurring on 15 or more days per month for more than 3 months, in which more than 8 days per month headache meet criteria for migraine with or without aura or respond to specific migraine treatment. The prevalence of chronic migraine is estimated between 1- 3% of general population. Persons with chronic migraine are more likely to suffer from severe disability; chronic migraine has an important socio-economic impact. Diagnostic approach in chronic migraine includes exclusion of a secondary headache disorder and confirmation of a primary episodic headache. When a patient is found to overuse pain medication, diagnosis of both chronic migraine and MOH should be considered. Treating episodic migraine early and managing attack frequency using preventive medication and behavioural interventions will be benefic in reducing the risk of chronicisation. Lifestyle changes are important for avoiding triggers for migraine attacks; treatment of comorbidities is equally important because these conditions exacerbate patient’s tendency to have headaches. The initial relief step for drug abusers always relies in drug withdrawal. For migraine attacks treatment begins with non-pharmacologic interventions (staying in a quiet, dark room, pressure on painful areas, applying cold compresses , simple OTC analgetics (NSAIDs, paracetamol, aspirin, acetaminophen. If these are not effective, triptans are the drugs of choice. Preventive treatment is always recommended in patients with chronic migraine because the high frequency of headache attacks.

In the history of the modern school systems in Europe, the development of the didactiques des disciplines (subject didactics) originates in 1) the building of “disciplines” (school subjects) as social organisations aimed at producing and diffusing knowledge and 2) the empowerment of the secondary school teachers through professional associations (Schneuwly, 2011). Subject didactics were thus born as practices of teaching a given discipline and attempts of theorising such practices. Against th...

To determine whether a 1-day behavioral intervention, aimed at enhancing psychological flexibility, improves headache outcomes of migraine patients with comorbid depression. Migraine is often comorbid with depression, with each disorder increasing the risk for onset and exacerbation of the other. Managing psychological triggers, such as stress and depression, may result in greater success of headache management. Sixty patients with comorbid migraine and depression were assigned to a 1-day Acceptance and Commitment Training plus Migraine Education workshop (ACT-ED; N = 38) or to treatment as usual (TAU; N = 22). Patients completed a daily headache diary prior to, and for 3 months following, the intervention. Clinical variables examined included headache frequency/severity, medication use, disability, and visit to a health care professional. Comparisons were made between baseline findings and findings at the 3-month follow up. Participants assigned to the ACT-ED condition exhibited significant improvements in headache frequency, headache severity, medication use, and headache-related disability. In contrast, the TAU group did not exhibit improvements. The difference in headache outcomes between ACT-ED and TAU was not statistically significant over time (ie, the treatment by time interaction was nonsignificant). These results complement those of a previous report showing effects of ACT-ED vs TAU on depression and disability. A 1-day ACT-ED workshop targeting psychological flexibility may convey benefit for patients with comorbid migraine and depression.These pilot study findings merit further investigation using a more rigorously designed large-scale trial.

2016-01-01

Migraine is a common disorder characterized by headache attacks frequently accompanied by vestibular symptoms like dizziness, vertigo, and balance disorders. Clinical studies support a strong link between migraine and vertigo rather than between other headache types and vertigo or nonvertiginous dizziness. There is a lack of consensus regarding the pathophysiology of migrainous vertigo. Activation of central vestibular processing during migraine attacks and vasospasm-induced ischemia of the labyrinth are reported as the probable responsible mechanisms. Because vestibular examination alone does not provide enough information for diagnosis of migrainous vertigo, posturography systems which provide objective assessment of somatosensory, vestibular, and visual information would be very helpful to show concomitant involvement of the vestibular and somato-sensorial systems. There are few posturographic studies on patients with migraine but it seems that how balance is affected in patients with migraine and/or migrainous vertigo is still not clear. We want to investigate balance function in migraineurs with and without vertigo with a tetra-ataxiometric posturography system and our study is the first study in which tetra-ataxiometric static posturography was used to evaluate postural abnormalities in a well-defined population of patients with migrainous vertigo.

Cerebral magnetic resonance imaging (MRI) was performed on 18 patients with migraine characterized by aura consisting of both visual symtoms and parasthesias. 15 headache-free individuals of the same age range were used as controls. Records were radomized and read in blind fashion by two neuroradiologists. Small subcortical white matter lesions were seen in three migraine cases and two controls. In one migraine case cortical infarctions were seen. In two controls, small areas of increased density similar to those in migraine were seen. No consistent correlation of migraine or its duration with cerebral atrophy was found. It is concluded that identification of both these MRI findings (small subcortical white lesions and cerebral atrophy) as significantly associated with migraine is doubtful. 21 refs., 2 figs.

Full Text Available In spite of the strong epidemiologic evidence linking migraine and ischemic stroke in young adults, the mechanisms explaining this association remain poorly understood. The observation that stroke occurs more frequently during the interictal phase of migraine prompts to speculation that an indirect relation between the two diseases might exist. In this regard, four major issues might be considered which may be summarized as follows: (1 the migraine-ischemic stroke relation is influenced by specific risk factors such as patent foramen ovale or endothelial dysfunction and more frequent in particular conditions like spontaneous cervical artery dissection; (2 migraine is associated with an increased prevalence of cardiovascular risk factors; (3 the link is caused by migraine-specific drugs; (4 migraine and ischemic vascular events are linked via a genetic component. In the present paper, we will review epidemiological studies, discuss potential mechanisms of migraine-induced stroke and comorbid ischemic stroke, and pose new research questions.

Pressman, Alice; Jacobson, Alice; Avins, Andy

2013-01-01

Background/Aims Migraine, a common neurological disorder, is among the top 20 causes of disability worldwide. One-year prevalence of migraine in the US is estimated to range from 8–15%, with women affected at approximately three times the rate of men. Current methods for migraine ascertainment from headache clinics and surveys are costly, affected by clinic-ascertainment bias, and do not work in situations where patient contact is not feasible. With the growing use of electronic medical records (EMR), new methods must be developed for identifying and tracking migraine prevalence over time. We sought to develop an EMR algorithm, to identify migraine, and to characterize its prevalence in Kaiser Permanente Northern California (KPNC). Methods From EMRs of all KPNC members, we collected all outpatient migraine diagnoses (ICD9 code 346.xx) and migraine-specific prescriptions (ergots, triptans, and acetaminophen with caffeine) for 2006–2010. We chart-reviewed a random sample to develop an electronic Migraine Probability Algorithm (score 0–100). We tested the algorithm in a second independent chart review. Using membership data, we calculated prevalences by age, race, and gender. Results We identified 313,174 KPNC members with evidence of migraine - 233,620 women and 79,554 men. The 5-year period-prevalence of migraine among KPNC adults was 17.1% for women and 5.9% for men. Among children, rates did not differ by gender (<2%) until the age of 10, when prevalences were higher - 5.8% for girls and 3.5% for boys. For women, prevalence peaked at ages 25–29. In contrast, males experienced flat prevalence with age (range 5%–6%). Overall, Whites had higher prevalence than Asians, but Blacks did not differ appreciably. Conclusions We used EMR data to capture migraine diagnoses and show prevalence patterns similar to those reported in the literature. Prevalence of diagnosed migraine in KPNC was 2.5–3 times higher in women than men; migraine peaked with age in women

Perceived stress is the most common trigger for migraine. The objective of this study was to examine the clinical significance of perceived stress in migraine patients. This is a case-control study. Consecutive migraine patients who visited a tertiary care hospital were enrolled for this study. They completed self-reported questionnaires including Perceived Stress Scale (PSS), 12-item Allodynia Symptom Checklist (ASC-12), Migraine Disability Assessment Scale (MIDAS), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), and Migraine-Specific Quality of Life Questionnaire (MSQ). Degree of perceived stress in migraine patients was measured and compared to that in healthy controls. Predictors for perceived stress and their impact on quality of life (QOL) of migraine patients were also determined. A total of 227 migraine patients were eligible for this study, including 103 (45.4%) who had chronic migraine (CM). Mean PSS score was significantly (p migraine is a critical factor for perceived stress. Perceived stress affects QOL of migraine patients.

To investigate migraine patterns in the United States using Google search data and utilize this information to better understand societal-level trends. Additionally, we aimed to evaluate time-series relationships between migraines and social factors. Extensive research has been done on clinical factors associated with migraines, yet population-level social factors have not been widely explored. Migraine internet search data may provide insight into migraine trends beyond information that can be gleaned from other sources. In this longitudinal analysis of open access data, we performed a time-series analysis in which about 12 years of Google Trends data (January 1, 2004 to August 15, 2016) were assessed. Data points were captured at a daily level and Google's 0-100 adjusted scale was used as the primary outcome to enable the comparison of relative popularity in the migraine search term. We hypothesized that the volume of relative migraine Google searches would be affected by societal aspects such as day of the week, holidays, and novel social events. Several recurrent social factors that drive migraine searches were identified. Of these, day of the week had the most significant impact on the volume of Google migraine searches. On average, Mondays accumulated 13.31 higher relative search volume than Fridays (95% CI: 11.12-15.51, P ≤ .001). Surprisingly, holidays were associated with lower relative migraine search volumes. Christmas Day had 13.84 lower relative search volumes (95% CI: 6.26-21.43, P ≤ .001) and Thanks giving had 20.18 lower relative search volumes (95% CI: 12.55-27.82, P ≤ .001) than days that were not holidays. Certain novel social events and extreme weather also appear to be associated with relative migraine Google search volume. Social factors play a crucial role in explaining population level migraine patterns, and thus, warrant further exploration. © 2017 American Headache Society.

We further discuss the control of cortical excitability by cannabinoids via inhibition of cortical spreading depression (CSD underlying the migraine aura. Finally, we present our view on perspectives of Cannabis-derived (extracted or synthetized marijuana components or novel endocannabinoid therapeutics in migraine treatment.

Harnessing migraines for neural regeneration

Directory of Open Access Journals (Sweden)

Jonathan M Borkum

2018-01-01

Full Text Available The success of naturalistic or therapeutic neuroregeneration likely depends on an internal milieu that facilitates the survival, proliferation, migration, and differentiation of stem cells and their assimilation into neural networks. Migraine attacks are an integrated sequence of physiological processes that may protect the brain from oxidative stress by releasing growth factors, suppressing apoptosis, stimulating neurogenesis, encouraging mitochondrial biogenesis, reducing the production of oxidants, and upregulating antioxidant defenses. Thus, the migraine attack may constitute a physiologic environment conducive to stem cells. In this paper, key components of migraine are reviewed – neurogenic inflammation with release of calcitonin gene-related peptide (CGRP and substance P, plasma protein extravasation, platelet activation, release of serotonin by platelets and likely by the dorsal raphe nucleus, activation of endothelial nitric oxide synthase (eNOS, production of brain-derived neurotrophic factor (BDNF and, in migraine aura, cortical spreading depression – along with their potential neurorestorative aspects. The possibility is considered of using these components to facilitate successful stem cell transplantation. Potential methods for doing so are discussed, including chemical stimulation of the TRPA1 ion channel, conjoint activation of a subset of migraine components, invasive and noninvasive deep brain stimulation of the dorsal raphe nucleus, transcranial focused ultrasound, and stimulation of the Zusanli (ST36 acupuncture point.

Full Text Available Hemiplegic migraine is a rare and complex disease, characterized by migraine with a reversible motor aura. Hemiplegic migraine can be easily misdiagnosed at its first presentation with an atypical severe form of migraine, a stroke, multiple sclerosis, metabolic disorders, conversion disorder or an epilepsy. We present the case of a young 24-year-old male patient, who since the age of 4 years had been having multiple episodes of migraine associated with hemiparesis, paraesthesia, prolonged somnolence, aphasia and confusion. We review the literature and discuss important diagnostic findings in hemiplegic migraine to help establishing a prompt diagnosis.

Role Variables VS. Contextual Variables in the Theory of Didactic Systems

Science.gov (United States)

Alberti, Monica; Cirina, Lucia; Paoli, Francesco

Partisans of the constructivist approach to mathematics education, such as Brousseau or Chevallard, developed an accurate theoretical framework in which didactical systems are viewed in a systemic perspective. What they somewhat fail to draw, however, is a sharp distinction between role variables - concerning the roles played in the didactical interaction by the individual elements of the system (Student-Teacher-Knowledge) - and contextual variables - concerning the action on the learning process of the system as a whole. Our research in progress on 2nd graders' word problem solving strategies applies the previous dichotomy to class management strategies adopted by teachers. Partial evidence collected so far points to the tentative conclusion according to which, contextual variables being equal, differences in teaching styles and methods may deeply reshape the role component of didactical systems. If we take into careful account this distinction, we can shed additional light into some hitherto unexplained phenomena observed in the literature.

In particular, when we turn our attention more to teaching and learning phenomena, especially to classroom phenomena, in which the teacher of specific disciplines assumes a non-supporting position in the process, we come to see a place of relevance for Didactics Sciences and Mathematics (DCeM. Thus, in this context, the present paper addresses works and discusses some trends in DCeM, without disregarding a historical-evolutionary scientific trajectory that culminated with its academic visibility, especially in the years of 1980 and 1990. In addition, a framework of globality can not be understood without an understanding of the function of its constituent parts. Thus, some assumptions of the Didactics of Mathematics (DM, Didactics of Physics (DF, Didactics of Chemistry (DQ and, finally, Didactics of Biology (DB provide the reader with the perception of invariant and recurrent elements In the studies in each area, with the bias of interest in their teaching. Therefore, work provides the dialectical process of substitution and old paradigms and the glimpse of new trajectories of research in teaching of Sciences and Mathematics that, despite its advances, cannot neglect the main scenario of the teacher's performance, that is, the classroom.

Managing migraine by patient profile: role of frovatriptan

Full Text Available Roger K Cady, Kathleen Farmer Headache Care Center, Springfield, MO, USA Abstract: For the last quarter of a century, triptans have been available for acute treatment of migraine but with little guidance on which of the different triptan products to use for which patient or which attack of migraine. In this article, we propose a structured approach to analysis of individual migraine attacks and patient characteristics as a means of defining and optimizing acute intervention. Assessment of patient and attack profiles includes the “5-Ps”: pattern, phenotype, patient, pharmacology, and precipitants. Attending to these five components of information can assist in developing an individualized behavioral, pharmacological, and nonpharmacological comprehensive treatment plan for most migraine patients. This clinical approach is then focused on frovatriptan because of its unique molecular signature and potential novel clinical applications. Frovatriptan like all triptans is indicated for acute treatment of migraine but its role has been explored in management of several unique migraine phenotypes. Frovatriptan has the longest half-life of any triptan and consequently is often promoted for acute treatment of migraine of longer duration. It has also been studied as a short-term preventive treatment in women with menstrual-related migraine. Given that 60% of female migraineurs suffer from menstrual-related migraine, this population is the obvious group for continued study. Small studies have also explored frovatriptan’s use in treating migraine predicted by premonitory symptoms as a preventive for the headache phase of migraine. By identifying patient and attack profiles, clinicians may effectively determine the viability of frovatriptan as an effective pharmacological intervention for migraine. Keywords: frovatriptan, acute treatment, preventive therapy, early intervention

Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management. Keywords: abdominal migraine, recurrent abdominal pain, abdominal epilepsy, cyclical vomiting

To describe the relationship between mood/anxiety disorders and migraine headaches emphasizing the frequency of episodes based in a cross-sectional analysis in the Brazilian Longitudinal Study of Adult Health. It has been suggested that frequency of migraine headaches can be directly associated with the presence of psychiatric disorders. Migraine headaches (International Headache Society criteria) was classified as migraine and 10,531 without migraine headaches (reference). Our main result was an increase in the strength of association between migraine and MDD as frequency of migraine increased for all sample: odds ratio of 2.14 (95% confidence interval [CI] 1.33-3.43) for migraine/month to 6.94 (95% CI 4.20-11.49) for daily headaches for all sample. Significant associations with migraine were also found for GAD, OCD, MADD, and CMD for total sample: MDD, GAD, OCD, MADD, and CMD for women, and MADD and CMD for men. Among men with daily migraine complaint, we found a significant association between migraine and OCD after correction for multiple comparisons (odds ratio 29.86 [95% CI 4.66-191.43]). Analyzing probable and definite migraine cases together, we replicated the findings in a lower magnitude. The increase in migraine frequency was associated with progressively higher frequencies of having mood/anxiety disorders in all samples suggesting for some psychiatric disorders a likely dose-response effect especially for women. © 2014 American Headache Society.

Education leads to better health-related decisions and protective behaviors, being especially important for patients with chronic conditions. Self-management education programs have been shown to be beneficial for patients with different chronic conditions and to have a higher impact on health outcomes than does didactic education. To investigate improvements in glycemic control (measured by glycated hemoglobin A1c) in patients with type 2 diabetes mellitus. Our comparative trial involved one group of patients receiving patient-centered education and another receiving didactic education. We dealt with selection bias issues, estimated the different impact of both programs, and validated our analysis using quantile regression techniques. We found evidence of better mean glycemic control in patients receiving the patient-centered program, which engaged better patients. Nevertheless, that differential impact is nonmonotonic. Patients initially at the healthy range at the patient-centered program maintained their condition better. Patients close to, but not within, the healthy range benefited equally from attending either program. Patients with very high glycemic level benefited significantly more from attending the patient-centered program. Finally, patients with the worst initial glycemic control (far from the healthy range) improved equally their diabetic condition, regardless of which program they attended. Different patients are sensitive to different categories of education programs. The optimal, cost-effective design of preventative programs for patients with chronic conditions needs to account for the different impact in different "patient categories." This implies stratifying patients and providing the appropriate preventative education program, or looking for alternative policy implementations for unresponsive patients who have the most severe condition and are the most costly.

Full Text Available To manage the impact of Industry 4.0 on industrial engineering (IE education curriculum requirements, realistic teaching and learning infrastructure such as a learning factory are required. This paper scans the literature to determine Industry 4.0’s principles and interactions with IE and a learning factory, surveys relevant universities by questionnaire to determine its current status and practices, and formulates didactic design parameters for an Industry 4.0 learning factory to support IE education in South Africa, making use of existing models of cyber-physical systems and learning factory morphology. In other results, the technical universities are discovered to be more positively disposed, in general terms, to developing an Industry 4.0 learning factory than are the traditional programmes which, with one exception, prefer computational facilities. Of ten universities that offer IE, only one — a traditional programme — has made significant progress towards creating an Industry 4.0 learning factory.

Full Text Available BACKGROUND Migraine is one of the common causes of headache in children. Migraine and epilepsy are both common episodic neurological disorders. The comorbidity of these two conditions is well known. Many researcher have pointed out that neuronal hyperexcitability is the initiating event for occurrence of migraine attack. The aim of the paper was to evaluate the EEG in children with migraine. MATERIALS AND METHODS We retrospectively analysed records of children who attended our paediatric outpatient department with diagnoses as suffering from migraine based on International Headache Society (IHS diagnostic criteria. Apart from detailed clinical history, EEG of every patient was collected and analysed. EEG was performed interictally at least 24 hours after the last episode of headache attack in all the cases. RESULTS 56 children (age range, 4-14 years constituted our study group. 64.3% children had migraine without aura (common type and in 23.2% cases had migraine with aura (classic type other were with migraine variants. Abnormal EEG was reported in 30.3% children. 17% of children with migraine without history of seizure had abnormal EEG. Sixty one percent of patients with aura had abnormal EEG. History of either febrile fits or afebrile fits was present in total 17.1% of cases. The type of paroxysmal discharges we came across was- a Sharp waves, b Spikes and c Spike and slow wave complexes. Abnormal paroxysmal sharp and spike-wave complexes (also called spike-and-slow-wave complexes were the most common EEG abnormality. CONCLUSION EEG abnormality was found in significant number of children with migraine both with and without history of seizure in our study. This indicates neuronal hyperexcitability during episodes of migraine. So, EEG should be considered in patients with clinical diagnoses of migraine to exclude association of any seizure activity.

We set out to evaluate the friendships and social behaviour of school-aged children with migraine. Concern exists regarding the impact of paediatric migraine on daily activities and quality of life. We hypothesized that children with migraine would have fewer friends and be identified as more socially sensitive and isolated than comparison peers. Sixty-nine children with migraine participated in a school-based study of social functioning. A comparison sample without migraine included classmates matched for gender, race and age. Children with migraine had fewer friends at school; however, this effect was limited to those in elementary school. Behavioural difficulties were not found. Middle-school students with migraine were identified by peers as displaying higher levels of leadership and popularity than comparison peers. Concern may be warranted about the social functioning of pre-adolescent children with migraine; however, older children with migraine may function as well as or better than their peers.

Based on recent findings and our own impressions we took a closer look at the relationship between (inter)ictal photophobia and psychometric variables in migraine patients with photophobia. For this study we included 29 (27 female) migraine patients and 31 (18 female) controls with a mean age of 31.6 ± 12.5 years and 24.0 ± 4.1 years, respectively. All participants filled out the Depression Anxiety Stress Scale (DASS). Interictal photophobia in patients was significantly higher than photophobia in controls (p = .001). Patients showed statistically significantly higher levels of depressive symptoms (p migraine and depression, it might be possible that depression contributes to interictal photophobia in patients with migraine. The same may be true for anxiety and stress. Both are also related to migraine and their possible impact on photophobia in migraine may be explained by pupillary dysfunction.

Full Text Available Objective: Migraine patients have tendency to have vestibular and auditory system problems. The aim of this study is to evaluate vestibule cochlear system of patients with migraine with Transient-evoked otoacoustic emissions (TEOAE video-nystagmography (VNG and caloric test. Methods:39 patients diagnosed with migraine and control group of 21 healthy volunteers were included in this study. Before they were included in the study, all of them were examined and those who has acute otitis media, chronic otitis media, tympanic membrane perforation, external otitis, ear surgery history and head trauma were excluded from the study. All patients and volunteers were tested by TEOAE, VNG and caloric tests. In evaluating the statistical data, SPSS 15.0 was utilized. Results: When TEOAE values for the migraine group and for the control group are compared, it is found statistically significant that the TEOAE values for the migraine group is lower than those for the control group. This result shows that there can be a pathology that is able to affect cochlear functions in migraine disease. As for VNG test results, a statistically significant difference cannot be determined between migraine and control groups. More over, the identification of canal paresis in caloric test indicates that peripheral vestibular problems accompany migraine disease. Conclusion:Evaluating vestibulocochlear system of migraine patients with TEOAE, VNG and caloric tests has been an important task for identifying vestibular imperfections accompanying these patients and for predicting potential auricular pathologies.

AVICENNA'S MEDICAL DIDACTIC POEM: URJUZEHTEBBI.

Science.gov (United States)

Nimrouzi, Majid; Salehi, Alireza; Kiani, Hossein

2015-01-01

Historical research shows that many physicians experienced in medical sciences are also talented in art, literature and poetry. Avicenna was a sage who was skilled in poetry in addition to philosophy and medicine. He wrote two different types of poetry: those meant to be enjoyed for their literary qualities of novelty and imagination, and his didactic Urjuzeh. Didactic poems are different from poetry evoked by imagination and feeling. In didactic poetry, the poets want to learn science and philosophy, whether spiritual, ethical or practical to the readers. Rhyme and poetry were often used for scientific writing in Avicenna's era, and were considered a method for memorizing scientific information and raising students' interest in difficult scientific concepts. Verse was used to simplify the didactic content, ease memorization and make difficult scientific issues more attractive. In medieval Persia, students of medicine had learned the basics of philosophy before starting medical courses. Poetry could help the students memorize the poem itself in combination with its meaning, in a way that was better and easier than prose. Avicenna's masterpiece, UrjuzehTebbi, comprises a perfect course in traditional Persian medicine in rhyming text written in Arabic. This great work was translated into Persian at the research centre for traditional medicine and history of medicine. We hope that the Persian translation of Urjuzeh Tebbi will allow students and experts to better appreciate the role of didactic poems in compiling and transmitting the concepts of Iranian medicine.

[The importance of chronic migraine in a general neurology service].

Gracia-Naya, M; Alarcia-Alejos, R; Modrego-Pardo, P J

Chronic migraine is a primary headache that is difficult to treat and has an important impact on the patient's quality of life. The international headache classification recently modified the criteria for chronic migraine and therefore few studies have been conducted that analyse groups according to these new criteria. AIM. To analyse a group of patients with chronic migraine who were referred to a general neurology service. The first 100 patients with migraine were selected. Researchers established and analysed a number of subgroups of patients with episodic, chronic or chronic migraine with probable headache due to medication abuse, in accordance with the International Headache Society (IHS) headache classification and its revised version from 2006. Of the total sample of 738 new patients, 100 (13.5%) suffered from migraines and of these 100 new patients with migraine 42 (5.6% of the total series) satisfied criteria for chronic migraine and 15 patients with chronic migraine met the criteria for probable headache due to medication abuse. Before visiting the neurology service, only 41% had been diagnosed as suffering from migraine, 38% had received no information about this condition, only 17% took triptans for symptomatic relief and 23% had followed some kind of preventive treatment. One notable finding was the importance of episodic and chronic migraine in a general neurology service, on applying the recent IHS criteria. A high percentage of patients with chronic migraine who were referred to the neurology service have not been diagnosed or given any information or proper treatment; an elevated degree of self-medication and medication abuse also exists. Preventive treatment and triptans in cases of intense migraines are still not commonly used in primary care.

Migraine headaches are a common neurological condition, negatively impacting health and quality of life. The association between migraines and spinal cord injury (SCI) is intriguing to consider from the perspective that migraine headaches may be acquired in response to damage in the spinal cord [corrected].The primary objective of this study was to further examine the association between SCI and migraine headache, controlling for potential confounding variables. A secondary objective was to determine the impact of migraine headaches on self-perceived health. Data from a sample of 61,047 participants were obtained from the cross-sectional Canadian Community Health Survey. Multivariable logistic regression was used to explore the association between SCI and migraine headache using probability weights and adjusting for confounders. The multivariable age- and sex-adjusted model revealed a strong association between SCI and migraine headache, with an adjusted odds ratio for migraine of 4.82 (95% confidence interval [3.02, 7.67]) among those with SCI compared to those without SCI. Further, individuals who experienced both SCI and migraine tended to report poorer perceived general health compared with the other groups (i.e., SCI and no migraine). In conclusion, this study established a strong association between SCI and migraine headache. Further research is needed to explore the possible mechanisms underlying this relationship. Improvements in clinical practice to minimize this issue could result in significant improvements in quality of life.

Migraine and asthma are comorbid chronic disorders with episodic attacks thought to involve inflammatory and neurological mechanisms. The objective of the present study is to investigate the relationship of asthma features between the asthma patients with migraine and those without migraine headache. A cross-sectional study was conducted from October 2015 to June 2016. Physician-diagnosed asthma patients aged 18 years and above were included. Demographic data, pulmonary function test and treatment of asthma were recorded. Asthma control was assessed using the asthma control test (ACT) and asthma control questionnaire (ACQ). The diagnosis of migraine was made by the neurologist with face-to face examinations based on the International Classification of Headache Disorders, third edition beta (ICHD-III-beta) criteria. Data about the age at onset, frequency of headache attacks, duration of headache attack, the presence of aura, and severity of headache were recorded. The severity of headache was evaluated using visual analogue scale (VAS). Overall 121 asthma patients were included in this study. Migraine was found to be present in 32 (26.4%) of patients. No statistically significant difference was found between asthma group and asthma with migraine groups in terms of pulmonary function test parameters. The mean ACT score in asthma with migraine patients group was significantly lower than the asthma groups. Morever, in the group asthma with migraine, a negative significant correlations were found between ACT scores with VAS scores. This study demonstrates that migraine headache may be associated with poor asthma control. On the other hand, it should not be forgotten that ACT is a subjective test and can be affected from by many clinical parameters.

Workplace disability in migraine: an Italian experience.

2004-10-01

Workplace disability due to migraine has not been extensively researched in non-English speaking countries. We assessed the repercussions of headache, and particularly of migraine, on work in a sample of employees from an Italian company (Bulgari). Information was obtained through a self-answering questionnaire in "all headaches" sufferers, and through direct interview in migraine sufferers (diagnosis according to IHS criteria). Headache frequency, pain intensity and headache-related disability were higher in migraineurs than in "all headaches" sufferers. About a quarter of migraineurs missed at least one day in the three months prior to the interview due to headache, and around 10% lost two or more days over the same period. Moore than 50% of migraineurs reported 1-7 days per month at work with headache, with reduction in productivity level by 50% or more in 15% of respondents. Our data confirmed that headaches, and particularly migraine, cause a considerable reduction in workplace productivity. Workplace interventions to effectively manage migraine are needed.

It presents the main findings and conclusions as regards the training of the teachers at these schools in the understanding of music and its didactic use. This study has allowed us to extract relevant conclusions about the preparation that the teachers have on music and its teaching as well as to determine their specific training needs. The conclusions drawn should, from our point of view, be necessarily born in mind in the design of the future Infant Education Teacher Training degree, which should lead to a suitable professional training for the integration of the music in the curriculum.

Optimizing prophylactic treatment of migraine: Subtypes and patient matching

Full Text Available Michel DibFédération du système nerveux central, Hôpital de la Salpêtrière, Assistance Publique- Hôpitaux de Paris, FranceAbstract: Advances in our understanding of the pathophysiology of migraine have resulted in important breakthroughs in treatment. For example, understanding of the role of serotonin in the cerebrovascular circulation has led to the development of triptans for the acute relief of migraine headaches, and the identification of cortical spreading depression as an early central event associated wih migraine has brought renewed interest in antiepileptic drugs for migraine prophylaxis. However, migraine still remains inadequately treated. Indeed, it is apparent that migraine is not a single disease but rather a syndrome that can manifest itself in a variety of pathological conditions. The consequences of this may be that treatment needs to be matched to particular patients. Clinical research needs to be devoted to identifying which sort of patients benefit best from which treatments, particularly in the field of prophylaxis. We propose four patterns of precipitating factors (adrenergic, serotoninergic, menstrual, and muscular which may be used to structure migraine prophylaxis. Finally, little is known about long-term outcome in treated migraine. It is possible that appropriate early prophylaxis may modify the long-term course of the disease and avoid late complications.Keywords: migraine, diagnosis, treatment, prophylaxis, subtypes

Studies on the Pathophysiology and Genetic Basis of Migraine

Gasparini, Claudia F; Sutherland, Heidi G.; Griffiths, Lyn R

2013-01-01

Migraine is a neurological disorder that affects the central nervous system causing painful attacks of headache. A genetic vulnerability and exposure to environmental triggers can influence the migraine phenotype. Migraine interferes in many facets of people’s daily life including employment commitments and their ability to look after their families resulting in a reduced quality of life. Identification of the biological processes that underlie this relatively common affliction has been difficult because migraine does not have any clearly identifiable pathology or structural lesion detectable by current medical technology. Theories to explain the symptoms of migraine have focused on the physiological mechanisms involved in the various phases of headache and include the vascular and neurogenic theories. In relation to migraine pathophysiology the trigeminovascular system and cortical spreading depression have also been implicated with supporting evidence from imaging studies and animal models. The objective of current research is to better understand the pathways and mechanisms involved in causing pain and headache to be able to target interventions. The genetic component of migraine has been teased apart using linkage studies and both candidate gene and genome-wide association studies, in family and case-control cohorts. Genomic regions that increase individual risk to migraine have been identified in neurological, vascular and hormonal pathways. This review discusses knowledge of the pathophysiology and genetic basis of migraine with the latest scientific evidence from genetic studies. PMID:24403849

The sample consisted of 115 males and 133 females (n=250 who were attending secondary vocational or technical schools in Slovenia. The students were included in an experimental project that introduced a “competence- based didactic unit” (CBDU in vocational schools’ curricula. In our study, the introduction of the CBDU was used to measure changes in the motivational, cognitive, and metacognitive aspects of self-regulated learning and to examine how they were subsequently related to other students characteristists, such as gender, school performance and time spent on school work. The results show the importance of CBDUs, on the one hand, on motivational factors such as intrinsic goal orientation, task value, and self-efficacy, and, on the other hand, differences in gender and grade level. The findings are discussed in terms of how teaching strategies in vocational education can contribute to the development of individuals’ motivation.

Full Text Available OBJECTIVE: The beneficial effects of angiotensin converting enzyme inhibitor drugs on migraine attack frequency have been shown. We aimed to study the relationship between the angiotensin converting enzyme gene and migraine pathophysiology. METHODS: In the present study, to assess whether the angiotensin converting enzyme insertion/deletion (I/D gene polymorphisms have an effect on migraine attacks, we studied the angiotensin converting enzyme genotypes of 102 migraine patients (35 cases of migraine with aura and 67 of migraine without aura and 75 age-and sex-matched normal volunteers. Frequency and age of onset of migraine attacks were also assessed according to angiotensin converting enzyme genotypes. RESULTS: Patients with migraine with and without aura were comparable with each other and the control group with respect to angiotensin converting enzyme genotypes (respectively; p= 0.88 and p= 0.76, p= 0.624. We could not determine a relationship between angiotensin converting enzyme genotypes and attack frequency (p= 0.125, but cases with angiotensin converting enzyme-II genotype showed a significantly younger age for onset of migraine attacks in comparison with the I/D genotype patients (p= 0.021. CONCLUSION: We believe that further angiotensin converting enzyme gene studies are warranted in younger age groups of patients with migraine and also in different populations

Muhammad Ali, Maria; Al Zayer, Maha

2015-01-01

Objective. To identify the frequency of typical (headache and dizziness) and common atypical (ear fullness, pressure, pain, tinnitus, facial fullness, and nasal congestion) migraine symptoms as chief complaints among patients presenting to otolaryngology clinic. Methods. This is a descriptive study of prospectively collected data from a general otolaryngology practice. Typical migraine presentations were diagnosed by applying international headache society (IHS) criteria for migraine headache and Neuhauser's criteria for migrainous vertigo. Atypical otologic and rhinologic migraine symptoms were diagnosed using individualized criteria. Charts were reviewed at 6-month interval from the first presentation. Results. Out of 1002 consecutive patients, 10.8% presented with “migrainous chief complaint.” All migrainous chief complaint patients had a history of headache but not all of them presented with headache. Corrected female to male ratio in the migraine group was 3 to 1; age distributions were significantly different between the migraine and nonmigraine groups by applying t-test. Out of the atypical complaints, 86% of the patients had a history of concomitant typical presentation. Conclusion. Actual diagnostic criteria for migraine do not satisfy the diversity of its presentation. Investigating the history of migraine is enough to diagnose most atypical presentations. Sound knowledge about migraine seems essential for any ENT practitioner. PMID:25695049

The co-existence of psychiatric comorbidities with migraine is well known; however, the relationship between alexithymia and migraine has not been persuasively shown yet. The aim of the study was to assess the relationships between migraine-related disability, depression, anxiety and alexithymia. One hundred and forty-five migraine patients (33.18 ± 8.6; 111 females, 34 males), and 50 control subjects (29.06 ± 7.6; 34 females, 16 males) were prospectively enrolled for the study. The participants completed a demographic data form and Migraine Disability Assessment Scale, Beck Depression Inventory, Beck Anxiety Inventory and Toronto Alexithymia Score-20 (TAS-20). All migraine patients were more depressive (p = 0.01) and anxious (p = 0.001) than the healthy subjects. TAS-20 scores of the migraine sufferers and the control group did not indicate alexithymia. The migraine-related disability of all migraine patients was severe (27.84 ± 29.22). Depression and anxiety scores in the migraine patients were highly correlated with each other and TAS-20 (r = 0.485, p = 0.001) and all its subscales in turn: difficulty in identifying (r = 0.435, p < 0.001) and describing feelings (r = 0.451, p = 0.001) and externally oriented thinking (r = 0.302, p = 0.001). Moreover, logistic regression analysis revealed that depression and anxiety predicted alexithymia. Our findings showed a complex relationship between migraine, depression, anxiety and alexithymia. On the other hand, alexithymia apparently was not directly connected to migraine, but its presence could be predicted in migraine patients because of co-morbid depression and anxiety.

Full Text Available Migraine headaches are a common neurological condition, negatively impacting health and quality of life. The association between migraines and spinal cord injury (SCI is intriguing to consider from the perspective that migraine headaches may be acquired in response to damage in the spinal cord [corrected].The primary objective of this study was to further examine the association between SCI and migraine headache, controlling for potential confounding variables. A secondary objective was to determine the impact of migraine headaches on self-perceived health. Data from a sample of 61,047 participants were obtained from the cross-sectional Canadian Community Health Survey. Multivariable logistic regression was used to explore the association between SCI and migraine headache using probability weights and adjusting for confounders. The multivariable age- and sex-adjusted model revealed a strong association between SCI and migraine headache, with an adjusted odds ratio for migraine of 4.82 (95% confidence interval [3.02, 7.67] among those with SCI compared to those without SCI. Further, individuals who experienced both SCI and migraine tended to report poorer perceived general health compared with the other groups (i.e., SCI and no migraine. In conclusion, this study established a strong association between SCI and migraine headache. Further research is needed to explore the possible mechanisms underlying this relationship. Improvements in clinical practice to minimize this issue could result in significant improvements in quality of life.

Our understanding of risk factors for childhood stroke is incomplete. In adults, migraine with aura is associated with a two-fold increase in ischemic stroke risk. In this cohort study we examine the association between migraine and stroke among children in Kaiser Permanente Northern California (KPNC). Children ages 2-17 years who were members of KPNC for ≥6 months between 1997 and 2007 were included. Migraine cohort members had one or more of: an ICD-9 code for migraine, migraine listed as a significant health problem, or a prescription for a migraine-specific medication. The comparison group was children with no evidence of headache. Main outcome measures included stroke incidence rates and incidence rate ratios (IR). Among the 1,566,952 children within KPNC during the study period, 88,164 had migraine, and 1,323,142 had no evidence of headache. Eight migraineurs had a stroke (three (38%) hemorrhagic; five (63%) ischemic). Eighty strokes occurred in children without headache (53 (66%) hemorrhagic; 27 (34%) ischemic). The ischemic stroke incidence rate was 0.9/100,000 person-years in migraineurs vs. 0.4/100,000 person-years in those without headache; IR 2.0 (95% CI 0.8-5.2). A post-hoc analysis of adolescents (12-17 years) showed an increased risk of ischemic stroke among those with migraine; IR 3.4 (95% CI 1.2-9.5). The hemorrhagic stroke incidence rate was 0.5/100,000 person-years in migraineurs and 0.9/100,000 person-years in those without headache; IR 0.6 (95% CI 0.2-2.0). There was no statistically significant increase in hemorrhagic or ischemic stroke risk in pediatric migraineurs in this cohort study. A post-hoc analysis found that ischemic stroke risk was significantly elevated in adolescents with migraine. Future studies should focus on identifying risk factors for ischemic stroke among adolescent migraineurs. Based on adult data, we recommend that migraine aura status should be studied as a possible risk factor for ischemic stroke among adolescent

We assessed frequency of vestibular symptoms in Headache Clinic patients over 10 years. A descriptive study of 5111 consecutive patients with tension-type headache or migraine, analyzed for dizziness/ vertigo accompanying headache and for a lifetime history of motion-sickness, cyclic vomiting, recurrent abdominal pain or atopy. Migraine patients were re-grouped as those with vestibular symptoms (dizziness/vertigo or motion sickness) and those without and their data then re-analyzed. There were 1880 migraine patients and 3231 tension-type headache patients. Significantly more migraine patients than tension-type headache patients experienced vestibular symptoms (p< 0.0001). The migraine with vestibular symptoms group was significantly younger (p< 0.05) had more aura, more phonophobia with migraine attacks (p< 0.0001). Menstruation and reported sleep problems impacted on headaches. While past history of cyclical vomiting, recurrent abdominal pain or atopy was about twice as common in migraine with aura and it was also more common in migraine with vestibular symptoms than migraine without vestibular symptoms. Vestibular symptoms are common in migraine patients. Migraine with vestibular symptoms might constitute a special group, one more likely to have had cyclic vomiting, recurrent abdominal pain or atopy.

Migraine Pathophysiology - Evolution Of Our Knowledge

Directory of Open Access Journals (Sweden)

Sinha K.K

2002-01-01

Full Text Available The biologic basis of migraine had remained unclear until about 15 years, but current migraine research has made some major advances to explain its mechanism. Migraine is currently conceived to originate in the brain. The trigger of an attack starts a depolarising event very similar to "spreading depression" of Leao in a brain that is already hyperexcitable. Hyperexcitability of cell membrane is perhaps genetically determined. Cortical depolarising events drive the trigeminovascular system through mechanisms that are largely hypothetical but might include a migraine generating centre in the brainstem to produce changes in the vessels of the cranium and meninges. Pain sensations carrying impulses are relayed back, first reaching the trigeminal ganglion caudalis and the trigeminal cervical complex in upper cervical cord from where they are relayed further up through various transmitting pathways to the brainstem, thalamus and the cortex where pain is finally perceived and registered.

2015-09-01

This review aims to provide a comprehensive overview of the literature on the use of exercise for migraine treatment with regard to its efficacy, mechanism of action and role in practice. Many randomized studies have reported the efficacy of prophylactic treatment of migrane with medications such as beta blockers or antiepileptic drugs. Studies on alternative approaches, like aerobic exercise and biofeedback, are however limited but also considered to be effective. Scientific databases were searched with keywords "exercise" and "migraine". The resulting publications were gathered, examined and discussed throughly. Past studies had limitations and were few in number, but more recent randomized controlled studies have concretely provided level of evidence about the effectiveness of exercise in prophylactic treatment of migraine. Core properties of exercise like intensity, duration, frequency, type and warming up period are required to be monitored while treating migraine to increase the beneficial effects and, also to prevent injuries and side effects which may include exertional headache. Isometric neck exercise is helpful when the migraine is accompanied by neck pain. Patient population with low beta endorphin level in blood, high physical fitness and high motivation receives significant benefits from the exercise treatment. The action of exercise on migraine is in general related to neurochemical factors, psychological states and increase in cardivascular and cerebrovascular fitness. Considering its effectiveness and minimal side effects, migraine patients should often be encouraged to practice physical exercise with intensity, frequency and duration that should be carefully instituted to achieve the most beneficial outcome while preventing potential injuries and side effects.

Full Text Available Abstract Background The objective of this study is to examine the stress and mood changes of Japanese subjects over the 1–3 days before a migraine headache. Methods The study participants were 16 patients with migraines who consented to participate in this study. Each subject kept a headache diary four times a day for two weeks. They evaluated the number of stressful events, daily hassles, domestic and non-domestic stress, anxiety, depressive tendency and irritability by visual analog scales. The days were classified into migraine days, pre-migraine days, buffer days and control days based on the intensity of the headaches and accompanying symptoms, and a comparative study was conducted for each factor on the migraine days, pre-migraine days and control days. Results The stressful event value of pre-migraine days showed no significant difference compared to other days. The daily hassle value of pre-migraine days was the highest and was significantly higher than that of buffer days. In non-domestic stress, values on migraine days were significantly higher than on other days, and there was no significant difference between pre-migraine days and buffer days or between pre-migraine days and control days. There was no significant difference in the values of domestic stress between the categories. In non-domestic stress, values on migraine days were significantly higher than other days, and there was no significant difference between pre-migraine days and buffer days or between pre-migraine days and control days. There was little difference in sleep quality on migraine and pre-migraine days, but other psychological factors were higher on migraine days than on pre-migraine days. Conclusion Psychosocial stress preceding the onset of migraines by several days was suggested to play an important role in the occurrence of migraines. However, stress 2–3 days before a migraine attack was not so high as it has been reported to be in the United States and

Weight change associated with the use of migraine-preventive medications.

Medications administered long term, such as those used for migraine prophylaxis, are often associated with weight change as a side effect. Such effects may compromise general health status, exacerbate coexisting medical conditions, and affect medication adherence. Weight gain should be of particular concern in patients with migraine, as there is evidence that overweight and obese patients with migraine are at risk for an increased frequency and severity of migraine attacks. This article reviews weight-change data from recent clinical studies of migraine-preventive medications in children, adolescents, and adults with migraine. A PubMed search was conducted for English-language articles published between January 1970 and November 2007. Among the search terms were migraine prevention, migraine prophylaxis, migraine treatment, antidepressant drug, beta-adrenergic-receptor blockers, antiepileptic drug, anticonvulsant drug, weight gain, and weight loss. Studies that reported weight-change data (gain, loss, or neutral) were included. When available, double-blind, placebo-controlled studies were selected for review. Open-label, retrospective or prospective trials may also have been included. Most of the migraine-preventive medications classified by the United States Headache Consortium as group 1 based on the high level of evidence for their efficacy--for instance, amitriptyline, propranolol, and divalproex sodium-have been associated with varying degrees of weight gain. The exceptions are timolol, which is weight neutral, and topiramate, which is associated with weight loss. Among the drugs that have been associated with weight gain, a higher incidence of weight gain was observed with amitriptyline and divalproex sodium than with propranolol. Weight-change effects require careful consideration when selecting migraine-preventive medications, and weight should be monitored carefully over the course of any migraine treatment plan.

Studies have suggested that contact between opposing mucosal surfaces in the nasal wall and cavity can be a target of the surgical treatment of migraines. Unfortunately, not enough is known about the role of nasal pathology in the pathogenesis of this condition. The co-existence of further rhinological disorders can be an impediment to defining the cause and effect of anatomical variants. The authors compared the MRI scans of migraine- and non-migraine patients (MPs and NMPs, respectively) to determine the prevalence of such mucosal contact points in order to extrapolate whether there is a significant association with migraines. Coronal and axial MRI brain scans of 522 patients (412 migraineurs and 110 non-migraineurs) were analysed for the prevalence of anatomical variations of the nasal cavity, e.g. concha bullosa, septal deviations, mucosal swelling and contact points. The results showed no significant difference between MPs and NMPs patients for any of the parameters examined. Moreover, 87% MPs and 79% NMPs had at least one contact point. The most frequent contact point was between the middle turbinate and the septum, observed in 54% of MPs and 45% of NMPs. Contact points with the nasal mucosa are highly prevalent in both MPs and NMPs. Although a contact point does not cause a migraine in the absence of the disease, the concomitant presence of migraine and contact points can trigger an attack, and therefore, it is necessary to differentiate or exclude a rhinological disorder in these patients.

Periodontal disease as a potential factor of migraine chronification.

Science.gov (United States)

Ameijeira, Pablo; Leira, Yago; Blanco, Juan; Leira, Rogelio

2017-05-01

Migraine is a hereditary constitutional base disorder, which is characterized by recurrent episodes of headache pulsatile characteristics associated with photophobia/phonophobia, nausea and/or vomiting. The main complication in migraine is the chronicity of the process, now recognized as a chronic migraine. Although pathogenic mechanisms that may influence the pathophysiology of migraine and its possible chronicity are not fully understood, previous studies have shown in patients with migraine molecular alterations of systemic inflammation, neurogenic inflammation, endothelial dysfunction, innate immunity, dysfunction of matrix proteases and blood-brain barrier. Periodontal disease is an inflammatory lesion caused by bacteria. After the bacterial infection begins, an immune response that will be responsible for individual susceptibility appears. More advanced forms of periodontitis have demonstrated molecular alterations of inflammation, endothelial dysfunction, dysfunction of matrix proteases and innate immunity, similar to those observed in migraine. Furthermore, the main molecular mediators of neurogenic inflammation related to activation of the trigeminovascular system, which are characteristic of migraine, are overexpressed in gingival crevicular fluid and mucosa in patients with periodontal disease. Hypertension, hypercholesterolemia, insulin resistance, stroke or coronary artery disease are comorbidities that periodontal disease and migraine could share. Therefore, several mechanisms and hypotheses could explain the possible association between both diseases. However, epidemiological and molecular studies will be necessary to provide a better understanding of this potential association, which could be implicated in the chronification of migraine.

Abstract Migraine is a highly prevalent and frequently disabling disorder. Since the pathogenesis of this condition has a strong inflammatory component and migraine is significantly associated with cardiovascular disease, we assess whether C-reactive protein (CRP) may be epidemiologically or casually linked with migraine. An electronic search on Medline, Scopus and Web of Science produced 17 studies reporting original data about the epidemiological association between CRP and migraine (1 retrospective, 1 interventional, 14 cross-sectional and 1 both interventional and cross-sectional). When all studies reporting sufficient data about CRP values were pooled (n=12; 6980 cases and 38,975 controls), the concentration of CRP was found to be significantly higher in patients with migraine than in controls (weighted mean difference 1.12 mg/L; 95% CI 1.01-1.25 mg/L; p<0.001). In further analysis of studies containing separate data for migraine with and without aura (n=7), CRP values remained significantly higher in both migraineur patients with aura (n=1939; weighted mean difference 0.88 mg/L; 95% CI 0.63-1.14 mg/L; p<0.001) or without aura (n=2483; weighted mean difference 1.04 mg/L; 95% CI 0.78-1.30 mg/L; p<0.001) when compared with controls (n=29,354). Despite a large inter-study heterogeneity (99.3%), our analysis provides evidence of a potential epidemiological association between increased concentration of CRP and migraine, thus paving the way for further clinical investigations about therapeutic agents that may contextually decrease the risk of cardiovascular disease and reduce the burden of migraine.

Pharmacological synergy: the next frontier on therapeutic advancement for migraine.

Blumenfeld, Andrew; Gennings, Chris; Cady, Roger

2012-04-01

The burden of migraine significantly impacts the individual sufferer, their families, the workplace, and society. The World Health Organization has identified migraine as an urgent public health priority and has initiated a global initiative to reduce the burden of migraine. Underlying the World Health Organization initiative is the need to discover means of optimizing migraine treatments and make them accessible to the broader portion of the world population. Development of acute migraine medications over the past several decades has largely centered on engineering highly specific receptor molecules that alter migraine pathophysiological mechanisms to abort or reverse the acute attack of migraine. The first product of this line of discovery was sumatriptan and heralded as a landmark therapeutic breakthrough. Sumatriptan is a 5-HT-1B/D receptor agonist considered to activate receptors involved in the pathophysiology specific to migraine. Large-scale regulatory/clinical studies demonstrated statistical superiority for sumatriptan over placebo in reduction or elimination of headache, nausea, photophobia, and phonophobia. Since the introduction of sumatriptan, 6 other triptan products have been released in the United States as acute treatments for migraine, all having the same mechanism of action and similar efficacy. Despite their utility as migraine abortive medications, the triptans do not successfully treat all attacks of migraine or necessarily treat all migraine associated symptoms. In fact, in less than 25% of attacks do subjects obtain and maintain a migraine-free response to treatment for at least beyond 24 hours. A wide range of non-triptan medications also have demonstrated efficacy in acute migraine. These include non-steroidal anti-inflammatory drugs (NSAIDs), opioids, phenothiazines, and valproic acid to name a few. Given the distinctly different mechanisms of actions of these various medications, it is likely that several unique pathophysiological

2011-08-01

Full Text Available Abstract Background Many migraineurs who seek care in headache clinics are refractory to treatment, despite advances in headache therapies. Epidemiology is poorly characterized, because diagnostic criteria for refractory migraine were not available until recently. We aimed to determine the frequency of refractory migraine in patients attended in the Headache Unit in a tertiary care center, according to recently proposed criteria. Methods The study population consisted of a consecutive sample of 370 patients (60.8% females with a mean age of 43 years (range 14-86 evaluated for the first time in our headache unit over a one-year period (between October 2008 and October 2009. We recorded information on clinical features, previous treatments, Migraine Disability Assessment Score (MIDAS, and final diagnosis. Results Overall migraine and tension-type headache were found in 46.4% and 20.5% of patients, respectively. Refractory migraine was found in 5.1% of patients. In refractory migraineurs, the mean MIDAS score was 96, and 36.8% were medication-overusers. Conclusions Refractory migraine is a relatively common and very disabling condition between the patients attended in a headache unit. The proposed operational criteria may be useful in identifying those patients who require care in headache units, the selection of candidates for combinations of prophylactic drugs or invasive treatments such as neurostimulation, but also to facilitate clinical studies in this patient group.

Several potential dietary trigger factors for migraine have been proposed. However, few studies have examined the intake pattern of these dietary items compared to adequate control populations and whether intake levels may vary by migraine aura status or attack frequency. We conducted a cross-sectional study among participants in the Women's Health Study. We used logistic regression to evaluate the association between migraine and headache status and low intake of foods commonly reported to affect migraine. A total of 25,755 women reported no history of migraine or headache, 5573 reported non-migraine headache and 7042 reported any migraine. Those with non-migraine headache or any migraine were more likely to have low intake of total alcohol (OR = 1.22, 95% CI:1.14-1.29 and OR = 1.17, 95% CI:1.11-1.24, respectively). Migraineurs with aura were more likely to have low intake of chocolate, ice cream, hot dogs, and processed meats. Those who experience migraine at least once per week were more likely to have low intake of skim/low-fat milk and white and red wine. Intake of most suggested migraine dietary triggers differs by migraine aura status and attack frequency, a pattern not found for non-migraine headache. © International Headache Society 2014.

Migraine headache and the presence of a patent foramen ovale have been associated with each other, although the precise pathophysiological mechanism(s) are uncertain. The purpose of this systematic review was to identify the extent of patent foramen ovale prevalence in migraineurs and to determine whether closure of a patent foramen ovale would improve migraine headache. An electronic literature search was performed to select studies between January 1980 and February 2013 that were relevant to the prevalence of patent foramen ovale and migraine, and the effects of intervention(s) on migraine attacks. Of the initial 368 articles presented by the initial search, 20 satisfied the inclusion criteria assessing patent foramen ovale prevalence in migraineurs and 21 presented data on patent foramen ovale closure. In case series and cohort studies, patent foramen ovale prevalence in migraineurs ranged from 14.6% to 66.5%. Case-control studies reported a prevalence ranging from 16.0% to 25.7% in controls, compared with 26.8% to 96.0% for migraine with aura. The extent of improvement or resolution of migraine headache attack symptoms was variable. In case series, intervention ameliorated migraine headache attack in 13.6% to 92.3% of cases. One single randomized trial did not show any benefit from patent foramen ovale closure. The data overall do not exclude the possibility of a placebo effect for resolving migraine following patent foramen ovale closure. This systematic review demonstrates firstly that migraine headache attack is associated with a higher prevalence of patent foramen ovale than among the general population. Observational data suggest that some improvement of migraine would be observed if the patent foramen ovale were to be closed. A proper assessment of any interventions for patent foramen ovale closure would require further large randomized trials to be conducted given uncertainties from existing trial data.

Migraine headache is a relatively common, debilitating condition that costs our healthcare system over 78 billion dollars per year. Riboflavin has been advocated as a safe, effective prophylactic therapy for the prevention of migraines. The purpose of this study was to provide a systematic review of the current role of riboflavin in the prophylaxis of migraine headache. A MEDLINE literature search inclusive of the dates 1966-2016 was performed using the search terms: riboflavin and migraine disorders. Excerpta Medica was searched from 1980 to 2016 using the search terms: riboflavin and migraine. Additionally, Web of Science was searched using the terms riboflavin and migraine inclusive of 1945-2016. Bibliographies of all relevant papers were reviewed for additional citations. We utilized the PRISMA guidelines to select English language, human, clinical trials of riboflavin as a single entity or in combination, review articles, and supporting pharmacokinetic and pharmacogenomic data assessing the efficacy and mechanism of riboflavin therapy in the prophylactic treatment of migraine headache. A total of 11 clinical trials reveal a mixed effect of riboflavin in the prophylaxis of migraine headache. Five clinical trials show a consistent positive therapeutic effect in adults; four clinical trials show a mixed effect in paediatric and adolescent patients, and two clinical trials of combination therapy have not shown benefit. Adverse reactions with riboflavin have generally been mild. Riboflavin is well tolerated, inexpensive and has demonstrated efficacy in the reduction of adult patient's migraine headache frequency. Additional data are needed, however, to resolve questions involving pharmacokinetic issues and pharmacogenomic implications of therapy. © 2017 John Wiley & Sons Ltd.

123 I-IMP-SPECT brain imaging was performed in patients with classic migraine (n = 5) and migraine accompagnee (n = 18) during the headache-free interval. A regional reduction of tracer uptake into brain was observed in all patients with migraine accompagnee, while in patients with classic migraine only one case showed an area of decreased activity. The most marked alteration was found in a patient with persisting neurological symptoms (complicated migraine). In most cases the areas of decreased tracer uptake corresponded to headache localization as well as to topography of neurologic symptoms during migraine attacks. It may be concluded that migraine attacks occur in connection with exacerbations of preexisting changes of cerebral autoregulation due to endogenous or exogenous factors

Data in the literature show that migraine tends to improve during pregnancy in most migrainous women. The aim of this Internet survey was to obtain the most likely cross section of the situation in the general population with respect to the presence and course of migraine in pregnancy. All women who participated were asked to answer questions pertaining to their history of pregnancy and headache. One thousand and eighteen women participated in the survey; only 775 met the eligibility criteria for inclusion. One hundred and ninety-five women (25.2 %) reported having had a headache only before pregnancy, 425 (54.8 %) before and during pregnancy, and 155 (20.0 %) only during pregnancy. Women suffering from headache before and/or during pregnancy were much more likely to have headaches with more migrainous features at the ID Migraine Screener test when compared to women whose headache began during pregnancy. "Definite migraines" were 277/620 (44.7 %) and 26/155 (16.8 %), respectively, in the two groups (p < 0.0001). Among the 620 females that suffered from headache before pregnancy, 375 (60.5 %) improved, 195 (31.5 %) showed complete resolution of the disorder, and 180 (29.0 %) had a reduction in headache frequency. Moreover, the multinomial logistic model (with headache pattern as dependent variable) proved fetal presentation as significant (p = 0.0042). Women with "new headache" (No/Yes pattern) had an OR (95 % CI) of 1.9 (1.2-3.0) of breech presentation at delivery versus those with a stable pattern of headache (Yes/Yes). Finally, women with not recent pregnancy stated they suffered from headache less than the women with recent pregnancy.

Numerous studies have indicated an increased risk for stroke in patients with migraine, especially migraine with aura; however, many studies used self-reported migraine and only a few controlled for familial factors. We aimed to investigate migraine as a risk factor for stroke in a Swedish population-based twin cohort, and whether familial factors contribute to an increased risk. The study population included twins without prior cerebrovascular disease who answered a headache questionnaire during 1998 and 2002 for twins born 1935-58 and during 2005-06 for twins born between 1959 and 1985. Migraine with and without aura and probable migraine was defined by an algorithm mapping on to clinical diagnostic criteria according to the International Classification of Headache Disorders. Stroke diagnoses were obtained from the national patient and cause of death registers. Twins were followed longitudinally, by linkage of national registers, from date of interview until date of first stroke, death, or end of study on 31 Dec 2014. In total, 8635 twins had any migraineous headache, whereof 3553 had migraine with aura and 5082 had non-aura migraineous headache (including migraine without aura and probable migraine), and 44 769 twins had no migraine. During a mean follow-up time of 11.9 years we observed 1297 incident cases of stroke. The Cox proportional hazards model with attained age as underlying time scale was used to estimate hazard ratios with 95% confidence intervals for stroke including ischaemic and haemorrhagic subtypes related to migraine with aura, non-aura migraineous headache, and any migraineous headache. Analyses were adjusted for gender and cardiovascular risk factors. Where appropriate; within-pair analyses were performed to control for confounding by familial factors. The age- and gender-adjusted hazard ratio for stroke related to migraine with aura was 1.27 (95% confidence interval 1.00-1.62), P = 0.05, and 1.07 (95% confidence interval 0.91-1.26), P = 0

Migraine is a common multifactorial and polygenic neurological disabling disorder characterized by a genetic background and associated to environmental, hormonal and food stimulations. A large series of evidence suggest a strong correlation between nutrition and migraine and indicates several commonly foods, food additives and beverages that may be involved in the mechanisms triggering the headache attack in migraine-susceptible persons. There are foods and drinks, or ingredients of the same, that can trigger the migraine crisis as well as some foods play a protective function depending on the specific genetic sensitivity of the subject. The recent biotechnological advances have enhanced the identification of some genetic factors involved in onset diseases and the identification of sequence variants of genes responsible for the individual sensitivity to migraine trigger-foods. Therefore many studies are aimed at the analysis of polymorphisms of genes coding for the enzymes involved in the metabolism of food factors in order to clarify the different ways in which people respond to foods based on their genetic constitution. This review discusses the latest knowledge and scientific evidence of the role of gene variants and nutrients, food additives and nutraceuticals interactions in migraine.

Crevits, Luc; Vanacker, Leen; Verraes, Anouk

2012-05-01

We wanted to study otolith function by measuring the static subjective visual vertical (SVV) in migraine patients and in controls with and without kinetosis (motion sickness). Forty-seven patients with moderately severe migraine and 96 healthy controls were enrolled. Using a questionnaire, persons with kinetosis were identified. The SVV test was performed in a totally dark room. Subjects wore a stiffneck to stabilize the head in an erect position. They were required to adjust an infrared line to the gravitational vertical with a hand-held infrared remote controlled potentiometer. The deviation of SVV in the group of migraine patients was not significantly different from that of controls, regardless of whether an aura was associated. SVV was not significantly influenced by the presence of dizziness/non specific vertigo or kinetosis. Patients with moderately severe migraine under prophylactic medication correctly estimate the visual verticality in the headache-free period. It is suggested that a deviation of SVV in a headache-free migraine patient may not be attributed to his migraine disorder as such regardless whether kinetosis is associated.

This research investigated empathy trends among physician assistant (PA) students through their education and included gender differences and specialty job interest. This research partially replicates similar studies of medical and other health professions students. The Jefferson Scale on Physician Empathy (SPE) was administered to PA students three times: (1) during matriculation, (2) near the end of their didactic training and (3) during their clinical education phase. Data were analyzed using both parametric (ANOVA) and nonparametric (binomial) methods. A total of 328 survey responses (270 females, 57 males, and one nonindicator) from the graduating classes of 2009 through 2014 at a northeastern university were collected and analyzed. Reliability for the JSPE was .80 (Cronbach) in this sample. Sixty-two percent had lower median JSPE empathy scores toward the end of their didactic training than at the time of matriculation (P = .0001), while the difference between empathy scores from years two and three was not significant (P = .37). Women were significantly more empathetic (mean = 5.05) at the time of matriculation than men (mean = 4.70, P = .0003), while both genders appeared to lose empathy in a parallel fashion during didactic training (P = .76). There was no association between empathy scores and prospective job category interest. These findings illustrate a decline in empathy among both genders during PA training, similar to other health care providers' educations, and support the need for further conversation regarding a role for empathy assessment and curricula in PA education.

Full Text Available Migraines and sleep terrors (STs are highly prevalent disorders with striking similarities. The aim of this study was to evaluate the effect of the antecedent of STs by comparing adolescents suffering from migraines with healthy controls in a large consecutive series. METHODS: All patients were subjected to a detailed headache questionnaire and were instructed to keep a headache diary during a two-month period. The age range was 10 to 19 years. The diagnosis of STs was defined according to the International Classification of Sleep Disorders. RESULTS: A total of 158 participants were evaluated. Of these participants, 50 suffered from episodic migraines (EMs, 57 had chronic migraines (CMs and 51 were control subjects (CG. Participants who had a history of STs had significantly more migraines than participants who did not. CONCLUSIONS: Migraine is strongly associated with a history of STs in the adolescent population independent of demographics and pain intensity.

The borderland of migraine and epilepsy in children.

Rajapakse, Thilinie; Buchhalter, Jeffrey

2016-06-01

To provide a review on the spectrum of migraine-epilepsy disorders in children. The migraine-epilepsy continuum covers a fascinating array of disorders that share many clinical similarities but also differ fundamentally in pathophysiology. In the pediatric population, its study can be complicated by the young age of those affected and the lack of clear understanding of the neurobiology of these disorders within the developing brain. This review serves to discuss the borderland of migraine and epilepsy in children. It will focus on epidemiology and comorbidity of the two disorders, possible mechanisms for shared pathophysiology informed by basic and translational science, and an overview of clinical similarities and differences. It will also discuss differentiation of migraine aura from childhood occipital epilepsies. Finally, the review concludes with a discussion of current classification methods for capturing cases on the migraine-epilepsy spectrum and a call for a united approach towards a better definition of this spectrum of disorders. Recent advances examining the migraine-epilepsy spectrum show clinicopathological similarities between the two disorders in children. Epidemiology demonstrates reciprocally increased incidences of epilepsy in migraineurs and of migraines in children with epilepsy, however, prospective longitudinal in children are currently lacking. Clinically, the two disorders show similarity in preictal, ictal, and postictal phenomena, with close temporal association of the two conditions described by the controversial term of "migralepsy." Basic science research has contributed significant improvements in understanding the generation of both of these episodic neurological conditions, with common links seen at a cellular level involving synaptic glutamate release and the provocation of varying propagation methods including cortical spreading depression in migraine and the paroxysmal depolarizing shift in epilepsy. Despite these significant

A situated didactics of the philosophy a model to attend the estrangement of the teachers

Laura Susana Morales

2013-01-01

Full Text Available Training for Philosophy teachers, in the deductive curriculum frames, generates strangeness in those who carry on their internship and their first labor practices, when they come back to school. How to attend this estrangement from a specific didactics of the philosophy without denying the tension among technical, practical and experiential foregrounds? For this, a model denominated as Philosophy’s specific situated didactics is suggested. Such didactics has in its basis, besides the consideration that education is constituted by the tension of the above mentioned foregrounds, a conception of the philosophy referred to as philosophizing Philosophy, which takes into consideration both the subject of the philosophical activity and the disciplinary object, and is opposed to the academism from a perspective that nourishes itself in the situated thought as a philosophic category and in the experience understood as the transformation of subject. That’s why the mentioned didactical model breaks with the explanation, as the university teaching axis, and relies on the narration as the contact point for those involved in the training of trainers and those who begin in Philosophy teaching.

Migraine is among the top 20 causes of disability. Menstruation is known to be a powerful trigger for migraine, and so is stress, but the presentation of headache is similar in both. Also, women are more vulnerable to stress as well as migraine, and this makes a complex relationship of menstruation, stress, and migraine. Objective: This study was done to understand the association of hormonal fluctuation in menstruation and stress with common migraine. Materials and methods: A cross-sectional comparative study was conducted in 40 young adult females, of whom 20 participants were cases of migraine without aura (18–35 years old, and the remaining 20 participants were age-matched controls. The study was done in Maulana Azad Medical College, New Delhi. Study participants were selected on the basis of International Headache Society (ICHD-IIA1.1 (2004 classification. Study participants with neurological disorders, chronic diseases, and disease suggestive of any hormonal disturbances were excluded. Clinically diagnosed migraine cases were asked to maintain a headache diary and to fill in the Depression Anxiety Stress Scales questionnaire. Biochemical assessment of hormonal status for thyroid-stimulating hormone, triiodothyronine, thyroxine, estrogen, follicle-stimulating hormone, luteinizing hormone, and prolactin was also done on the second day of their menstrual cycle. We used the Mann–Whitney U test to compare hormonal levels

To investigate the headache characteristics and clinical features of elderly migraine patients at a tertiary headache center. We retrospectively reviewed 239 records of migraine patients, over the age of 64 at the first visit, who had migraine as defined by the International Classification of Headache Disorders 3rd edition (beta version) from 2006 to 2015 based on the Marseille registry at Timone Hospital. 13.8% (33/239) patients had migraine with aura only, 13.0% (31/239) had both diagnoses. Of the patients who presented with migraine with aura, 13.4% (32/239) presented with aura without headache. Unilateral pain location was reported by 58.6% (140/239) of patients and the throbbing type of pain was present in 50.2% (120/239) of our study group. Photo- and phonophobia were observed in 77.4% (185/239) and 79.5% (190/239) of patients. Seventy-nine out of 239 (30.1%) patients were found to have probable medication overuse. Within this group, 31.65% (25/79) overused triptan and 70.9% (56/79) overused combination analgesics. We found higher frequencies of migraine for patients whose age at onset of migraine was younger than 18 years, and low frequency migraine was reported more frequently in the later onset group (P = .0357). We assess the headache characteristics of elderly migraine patients who were seen at our tertiary headache center and report the high frequency of probable medication overuse headache in this study group. Finally, we suggest that age of onset is an important factor in the clinical profile of these patients. © 2017 American Headache Society.

Chocolate and migraine: the history of an ambiguous association.

Lippi, Giuseppe; Mattiuzzi, Camilla; Cervellin, Gianfranco

2014-12-17

Migraine is a highly prevalent condition and an important cause of disability. Although the pathogenesis of this condition is complex and multifaceted, several environmental factors have been associated with development and aggravation of headache attacks. Among the various foods that have been implicated in migraine, chocolate has been regarded as detrimental on the basis of old and mostly anecdotal evidence. Therefore, this article is aimed to provide an overview on the current scientific evidence about the relationship between chocolate and migraine. Taken together, the information gathered from epidemiological and provocative studies attests that the potential causal association between chocolate and migraine remains largely enigmatic. The analysis of epidemiological surveys reveals a highly heterogeneous picture, with frequency of migraine episodes attributable to chocolate ranging from 0 to 22.5%. Even in those studies reporting a more convincing association, the risk of migraine after chocolate ingestion was found to be 2- to 3-fold lower than that reported for exposure to other conventional triggers such as stress, fasting, lack of sleep and alcohol beverages. The results of the double-blind studies are instead unequivocal, and clearly demonstrate that the risk of developing a headache attack after ingestion of chocolate is as likely as administering placebo in patients with migraine. It can hence be concluded that the widespread belief that chocolate and cocoacontaining foods should be absolutely avoided by migraine patients lacks of a reliable scientific basis.

This study aimed at analyzing the representations regarding the relationships between Nursing and Education practices, to reveal expectations regarding the course Fundamentals, Methods and Techniques of Teaching and evaluate the use of the Projects Method. Method this is a qualitative evaluation research performed between April and June 2007 with first-year nursing students of a Baccalaureate Degree Program. The data were analyzed based on the Social Representations framework and the constructivist postulates. The students revealed that their learning expectations were related with the contents of didactics, human communication, and the teaching-learning process. The Projects Method was considered capable of providing dynamism, interest towards the content, and the ability to associate theory and practice, in addition to having favored the amplitude and appreciation of the educate/care binomial. In conclusion, health didactics contents are capable of generating students' interest, especially when an innovative methodology is used.

To describe and analyse to what extent the goals of the education in promoting culturally competent nursing care have been achieved from a student perspective. As Sweden has transformed into a multicultural society over the past 50 years, there is a need to specify, at all levels of the nursing programme, transcultural concepts for the success of integration. A research-based didactic model was designed for the nursing programme at Malmö University and this was followed by investigations of its outcome. The study is a prospective cohort study with an outcome analysis. A descriptive research study with a longitudinal design was performed, with the focus on Swedish nursing students' experiences of transcultural nursing knowledge and their attitudes before and after implementation of the didactic model. The students evaluate highly their competence to meet demands of multicultural health and medical service. Additionally, their ability to recognise and understand the consequences of international migration on health also received a high mean. The study revealed the knowledge and experience acquired by Swedish students in transcultural nursing. The assumption was that a visible development of knowledge should occur during the three years of education. Interpreting the findings, such effectiveness can be found and hopefully the students will be able to give holistic nursing care based on a person's individual culture.

Full Text Available Migraine is the most common neurological disorder, and contributes to disability and large healthcare costs in the United States and the world. The treatment of migraine until recently has focused on medications, both abortive and prophylactic, but treatment of chronic migraine has been revolutionized with the introduction of botulinum toxin injection therapy. In this review, we explore the current understanding of migraine pathophysiology, and the evolution of the use of botulinum toxin therapy including proposed pathophysiological mechanisms through animal data. We also discuss the similarities and differences between three injection techniques.

Migraine has a 1-year prevalence of 10% and high socioeconomic costs. Despite recent drug developments, there is a huge unmet need for better pharmacotherapy. In this review we discuss promising anti-migraine strategies such as calcitonin gene-related peptide (CGRP) receptor antagonists and 5....... Tonabersat, a cortical spreading depression inhibitor, has shown efficacy in the prophylaxis of migraine with aura. Several new drug targets such as nitric oxide synthase, the 5-HT(1D) receptor, the prostanoid receptors EP(2) and EP(4), and the pituitary adenylate cyclase receptor PAC1 await development....... The greatest need is for new prophylactic drugs, and it seems likely that such compounds will be developed in the coming decade....

Acupuncture for migraine prophylaxis

Klaus Linde

Full Text Available ABSTRACT BACKGROUND: Acupuncture is often used for migraine prophylaxis but its effectiveness is still controversial. This review (along with a companion review on 'Acupuncture for tension-type headache' represents an updated version of a Cochrane review originally published in Issue 1, 2001, of The Cochrane Library. OBJECTIVES: To investigate whether acupuncture is a more effective than no prophylactic treatment/routine care only; b more effective than 'sham' (placebo acupuncture; and c as effective as other interventions in reducing headache frequency in patients with migraine. METHODS: Search methods: The Cochrane Pain, Palliative & Supportive Care Trials Register, CENTRAL, MEDLINE, EMBASE and the Cochrane Complementary Medicine Field Trials Register were searched to January 2008. Selection criteria: We included randomized trials with a post-randomization observation period of at least 8 weeks that compared the clinical effects of an acupuncture intervention with a control (no prophylactic treatment or routine care only, a sham acupuncture intervention or another intervention in patients with migraine. Data collection and analysis: Two reviewers checked eligibility; extracted information on patients, interventions, methods and results; and assessed risk of bias and quality of the acupuncture intervention. Outcomes extracted included response (outcome of primary interest, migraine attacks, migraine days, headache days and analgesic use. Pooled effect size estimates were calculated using a random-effects model. MAIN RESULTS: Twenty-two trials with 4419 participants (mean 201, median 42, range 27 to 1715 met the inclusion criteria. Six trials (including two large trials with 401 and 1715 patients compared acupuncture to no prophylactic treatment or routine care only. After 3 to 4 months patients receiving acupuncture had higher response rates and fewer headaches. The only study with long-term follow up saw no evidence that effects dissipated up

Linking didactics and research in instructional material: A new structural model

DEFF Research Database (Denmark)

Graf, Stefan Ting

2009-01-01

How can research in instructional materials become more relevant for didactics and instruction planning? And how can general didactics reflect questions developed from a media perspective. These are the guiding questions of the article, which assumes a gap between general didactics and research...... and theory of instructional material. General didactics does not sufficiently incorporate a theory of media, and research and theory in instructional material do not recognise general didactics and apply very different conceptions of instruction in their studies – if at all. Through two approaches we argue...... for a new basic structure in didactics in order to bridge the gap when relevant conclusions for pragmatic didactics are in question. The first approach accounts for the place and status of media in the most known structural theories in general didactics. The second approach argues from another angle...

Prophylactic treatment of migraine; the patient's view, a qualitative study

Directory of Open Access Journals (Sweden)

Dekker Frans

2012-03-01

Full Text Available Abstract Background Prophylactic treatment is an important but under-utilised option for the management of migraine. Patients and physicians appear to have reservations about initiating this treatment option. This paper explores the opinions, motives and expectations of patients regarding prophylactic migraine therapy. Methods A qualitative focus group study in general practice in the Netherlands with twenty patients recruited from urban and rural general practices. Three focus group meetings were held with 6-7 migraine patients per group (2 female and 1 male group. All participants were migraine patients according to the IHS (International Headache Society; 9 had experience with prophylactic medication. The focus group meetings were analysed using a general thematic analysis. Results For patients several distinguished factors count when making a decision on prophylactic treatment. The decision of a patient on prophylactic medication is depending on experience and perspectives, grouped into five categories, namely the context of being active or passive in taking the initiative to start prophylaxis; assessing the advantages and disadvantages of prophylaxis; satisfaction with current migraine treatment; the relationship with the physician and the feeling to be heard; and previous steps taken to prevent migraine. Conclusion In addition to the functional impact of migraine, the decision to start prophylaxis is based on a complex of considerations from the patient's perspective (e.g. perceived burden of migraine, expected benefits or disadvantages, interaction with relatives, colleagues and physician. Therefore, when advising migraine patients about prophylaxis, their opinions should be taken into account. Patients need to be open to advice and information and intervention have to be offered at an appropriate moment in the course of migraine.

Several genome-wide association studies (GWASs) in Caucasian populations have identified 12 loci that are significantly associated with migraine. More evidence suggests that serotonin receptors are also involved in migraine pathophysiology. In the present study, a case-control study was conducted in a cohort of 581 migraine cases and 533 ethnically matched controls among a Chinese population. Eighteen polymorphisms from serotonin receptors and GWASs were selected, and genotyping was performed using a Sequenom MALDI-TOF mass spectrometry iPLEX platform. The genotypic and allelic distributions of MEF2D rs2274316 and ASTN2 rs6478241 were significantly different between migraine patients and controls. Univariate and multivariate analysis revealed significant associations of polymorphisms in the MEF2D and ASTN2 genes with migraine susceptibility. MEF2D, PRDM16 and ASTN2 were also found to be associated with migraine without aura (MO) and migraine with family history. And, MEF2D and ASTN2 also served as genetic risk factors for the migraine without family history. The generalized multifactor dimensionality reduction analysis identified that MEF2D and HTR2E constituted the two-factor interaction model. Our study suggests that the MEF2D, PRDM16 and ASTN2 genes from GWAS are associated with migraine susceptibility, especially MO, among Chinese patients. It appears that there is no association with serotonin receptor related genes. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Despite the significant impact of migraine on patients and societies, few studies in low- and middle-income countries (LMICs) have investigated the association between migraine and suicidal behavior. The objective of our study is to examine the extent to which migraines are associated with suicidal behavior (including suicidal ideation, plans, and attempts) in a well-characterized study of urban dwelling Ethiopian adults. We enrolled 1060 outpatient adults attending St. Paul hospital in Addis Ababa, Ethiopia. Standardized questionnaires were used to collect data on socio-demographics, and lifestyle characteristics. Migraine classification was based on the International Classification of Headache Disorders-2 diagnostic criteria. The Composite International Diagnostic Interview (CIDI) was used to assess depression and suicidal behaviors (i.e. ideation, plans and attempts). Multivariable logistic regression models were used to estimate adjusted odds ratio (AOR) and 95% confidence intervals (95% CIs). The prevalence of suicidal behavior was 15.1%, with a higher suicidal behavior among those who had migraines (61.9%). After adjusting for confounders including substance use and socio-demographic factors, migraine was associated with a 2.7-fold increased odds of suicidal behavior (AOR = 2.7; 95% CI 1.88-3.89). When stratified by their history of depression in the past year, migraine without depression was significantly associated with suicidal behavior (AOR: 2.27, 95% Cl: 1.49-3.46). The odds of suicidal behavior did not reach statistical significance in migraineurs with depression (AOR: 1.64, 95% CI: 0.40-6.69). Our study indicates that migraine is associated with increased odds of suicidal behavior in this population. Given the serious public health implications this has, attention should be given to the treatment and management of migraine at a community level.

2010-01-01

In spite of the strong epidemiologic evidence linking migraine and ischemic stroke in young adults, the mechanisms explaining this association remain poorly understood. The observation that stroke occurs more frequently during the interictal phase of migraine prompts to speculation that an indirect relation between the two diseases might exist. In this regard, four major issues might be considered which may be summarized as follows: (1) the migraine-ischemic stroke relation is influenced by s...

Migraine is a highly disabling primary headache associated with a high socioeconomic burden and a generally high prevalence. The clinical management of migraine remains a challenge. This study was undertaken to identify potential serum biomarkers of migraine. Using Liquid Chromatography coupled to Mass Spectrometry (LC-MS), the metabolomic profile of migraine was compared with healthy individuals. Principal component analysis (PCA) and Orthogonal partial least squares-discriminant analysis (orthoPLS-DA) showed the metabolomic profile of migraine is distinguishable from controls. Volcano plot analysis identified 10 serum metabolites significantly decreased during migraine. One of these was serotonin, and the other 9 were amino acids. Pathway analysis and enrichment analysis showed tryptophan metabolism (serotonin metabolism), arginine and proline metabolism, and aminoacyl-tRNA biosynthesis are the three most prominently altered pathways in migraine. ROC curve analysis indicated Glycyl-l-proline, N-Methyl-dl-Alanine and l-Methionine are potential sensitive and specific biomarkers for migraine. Our results show Glycyl-l-proline, N-Methyl-dl-Alanine and l-Methionine may be as specific or more specific for migraine than serotonin which is the traditional biomarker of migraine. We propose that therapeutic manipulation of these metabolites or metabolic pathways may be helpful in the prevention and treatment of migraine. Copyright © 2018 Elsevier Inc. All rights reserved.

Marques Barrio, Juan Bernardino

Even though the advances are sharp in the processes of educational research in some areas of the natural sciences, is not possible to declare the same in the case of the Astronomy, where there is a huge hollow. Therefore, the necessity of innovative research in the teaching and learning of Astronomy is really large because is one of the main ways to break the ignorance barrier. Taking into consideration the fact that the heuristic, communicative and educational values in the use of the history of the Astronomy and its interaction with other areas supply an interesting dynamic view to the teaching effort, that is possible to take advantage of that to become aware of the existence of previous ideas and its possible study, in the first moment of the paper we present a panoramic view of the Astronomy around the world: creational myths, interaction with the culture, etc. Since reflect in a critical way about the educational activity is not only consider our practical activity fruit of the exposure of theories, but also consider the theory as a result of our practices, we have chosen the investigation-action as the methodology to be applied on the lessons. Then, we could verify, with the bibliographic review about the didactic processes used to transmit the astronomical knowledge, the arguable existing theoretical framework and the reasearches about teaching and learning of Astronomy, the scarce research and the need of innovate in this field. On the other hand, the process of investigation-action developed, using the Planetarium as a didactic resource in the teaching process, at the same time allow us to state that the Planetarium cover the three basic functions of a didactic middle---bearer of contents, to motivate and to structure---and also declare, in opposition to the view of some authors, that this middle should be, and in fact it is, a big allied to reach the conceptual contents and not only the attitudinal and contents related to the procedure.

2010-08-01

Full Text Available This paper is devoted to the procedure of realization of the main didactic principle – use visual method which becomes an essential factor of student perception of educational sources. The procedure is realized with series of laboratory works which are based on the principle – “device-computer-software”. The transformers of a physical magnitude into electrical signal are used in laboratory works. The combination of these transformers and a computer form the device which can measure a physical magnitude. The software allows reconstructing a virtual field distribution of this magnitude in area and observing its history. MATLAB is used as software and it provides with computation of different physical processes. The proposed procedure provides with a direct visual method and an indirect one as well. This matter promotes forming future specialists’ professional competence.

Gottlieb, Michael; Riddell, Jeff; Njie, Abdoulie

2017-01-01

National conference didactic lectures have traditionally featured hour-long lecture-based presentations. However, there is evidence that longer lectures can lead to both decreased attention and retention of information. The authors sought to identify trends in lecture duration, lecture types, and number of speakers at four national emergency medicine (EM) conferences over a 6-year period. The authors performed a retrospective analysis of the length, number of speakers, and format of didactic lectures at four different national EM conferences over 6 years. The authors abstracted data from the national academic assemblies for the four largest not-for-profit EM organizations in the United States: American Academy of Emergency Medicine, American College of Emergency Physicians, Council of Emergency Medicine Residency Directors, and Society for Academic Emergency Medicine. There was a significant yearly decrease in the mean lecture lengths for three of the four conferences. There was an increase in the percentage of rapid fire sessions over the preceding 2 years with a corresponding decrease in the percentage of general educational sessions. There was no significant difference in the mean number of speakers per lecture. An analysis of 4210 didactic lecture sessions from the annual meetings of four national EM organizations over a 6-year period showed significant decreases in mean lecture length. These findings can help to guide EM continuing medical education conference planning and research.

Evaluating the need for alternative didactic learning options in pediatric dental residency training.

Keck, Douglas B; Rutkauskas, John S; Clothey, Rebecca A

2009-06-01

The need for an alternative means of delivery of a didactic curriculum to pediatric dental residents is described. It is our hope with this project to encourage a much-needed didactic curriculum for programs lacking faculty and to endorse other programs in which academicians exist but cannot cover all the material with which a resident needs to become familiar in the two years of postgraduate residency training. A decrease in faculty number due to retirement, debt burden, or marginal recruitment techniques along with an increase in positions in pediatric dentistry residency programs poses a unique educational dilemma. Using a mixed-method research methodology, we sent a twelve-question survey to 105 pediatric dentistry residency program directors and department chairs, followed by eight telephone interviews. Results from a 55 percent return rate show that the debt burden of most pediatric dental residents is well over $100,000 and that this affects a resident's decision to enter academia, as does the relative lack of positive recruitment techniques and poor faculty remuneration. The survey results affirm the need for improvement in the didactic curriculum of pediatric dentistry residents and show that program directors and department chairs also feel that an alternative delivery method using DVD or online/web-based programs would be welcomed. Despite their extremely heavy workloads, educators are willing to contribute by providing lectures or reading lists in their area of expertise.

Full Text Available Objective: To investigate the impact of serum 25-hydroxyvitamin D levels on migraine headache in migraineurs Patients and Methods: A total of 72 patients were included in the study. Serum vitamin D concentration and its impact on the migraine headache were assessed in migraineurs and migraine subgroups. To assess serum levels of vitamin D, 25(OH D3 was measured by enzymelinked immunosorbent assay (ELISA. Patients were categorized as follows based on the results of serum vitamin D measurements. Severity of migraine, average duration and frequency of attacks per month were recorded. The headache diary result (HDR was determined as: Duration of headache × frequency of headache. Results: Average vitamin D level was 7.4 ng/ml among patients with migraine with aura group and 8.5 ng/ml in patients with migraine without aura. Severe vitamin D deficiency was detected in 14 (66.7% patients with migraine with aura and 9 (64.3% patients with migraine without aura, with no statistically significant difference between the two groups. No significant correlation was found between vitamin D levels and HDR among migraineurs (r=-0.042, p=0.812 as well as in patients with migraine with aura (r=0.044, p=0.842 and in patients with migraine without aura (r=0.059, p=0.842 versus control group with respect to HDR and vitamin D levels. The severity of migraine pain was not associated with vitamin D levels. Serum vitamin D concentration was lower in male patients versus control group. Conclusion: The impact of vitamin D on the severity and number of migraine attacks is not clear. Further studies are needed to demonstrate the association between vitamin D status and neurological diseases.

We investigated the diffusion-weighted MRI changes, apparent diffusion coefficient (ADC) values, and conventional MRI findings in specific brain areas during migraine attacks in patients with and without aura. Included in the study were 22 patients (2 male, 20 female) aged between 17 and 49 years who were diagnosed as having migraine according to the diagnostic criteria of the International Headache Society. Also included in the study were 18 age- and sex-matched healthy volunteers. Hyperintense lesions were evaluated in conventional MR images. Heavily diffusion-weighted images, ADC maps, and segmented ADC maps generated for regional ADC (rADC) measurements, were also studied. ADC values from specific brain areas were used with appropriate region of interests (ROI). Migraine with aura was diagnosed in 13 patients and migraine without aura was diagnosed in 9 patients. A total of 23 hyperintense lesions within the periventricular white matter and deep white matter were detected in five patients (21.8%). All of these hyperintense lesions were seen in migraine patients with aura. In only one patient did a hyperintense lesion show an increased diffusion pattern on diffusion-weighted images and ADC maps. One hyperintense lesion was detected in the control group (5.5%). There was no significant difference in ADC values between the migraine and control groups. T2-weighted hyperintense lesions were significantly more frequent in migraine patients especially in those with aura than in the control group. No diffusion alterations in diffusion-weighted images were detected in the infra- and supratentorial brain areas during migraine attacks in patients with and without aura. (orig.)

Full Text Available The purpose of the research, carried out in a sample of Slovene students, was to determine how subjects with migraine differ from subjects with migrainous disorder, subjects with non-migrainous headaches and subjects without recurrent headaches. The existence of migraine was assessed by UCSD migraine questionnaire, aggressiveness by Buss-Durkee hostility inventory and characteristics of object-relations by Bell object relations and reality testing inventory - form O. Subjects with migraine express significantly more negativism, indirect aggressiveness, irritability, hostility, suspicion and feelings of guilt than subject without recurrent headaches, while there are no differences in physical and verbal aggressiveness. There are less significant differences among subjects with different types of headache (migraine, migrainous disorder, non-migrainous headaches. Subjects with migraine and subjects without recurrent headaches differ significantly in characteristics of object-relations, subjects with migraine having more disturbed object-relations. Subject with different types of headaches do not differ in characteristics of object-relations. It is concluded that subjects with migraine have a raised level of aggressiveness, especially of indirect forms, which can indicate non-neutralized aggressiveness, and their object-relations are more disturbed.

There are contrasting results obtained in migraineurs concerning the levels and the role of both pro-inflammatory and anti-inflammatory cytokines. In this study, the association of the occurrence and clinical characteristics of migraine with the polymorphisms of tumor necrosis factor alpha (TNF-alpha) -308 G/A (rs1800629), interleukin-1alpha (IL-1alpha) +4845 G/T (rs17561), IL-1beta+3953 C/T (rs1143634) and interleukin-1 receptor antagonist variable number tandem repeat (IL-1RA VNTR) genes were studied. We also investigated the genetic linkage between these genes. Sixty-seven patients with migraine without aura (MwoA) and 96 unrelated, age- and sex-matched migraine-free, healthy control subjects from the same geographic area were investigated. We observed significant differences in the genotypic distribution of the TNF-alpha-308 G/A and IL-1beta+3953 C/T polymorphism for migraineurs compared with controls (P = 0.004). Frequency of the TNF-alpha-308 GG genotype was higher in the control group than MwoA group (82.1% vs 55.2%). Differences in the distribution of the allele frequencies were also observed, being the TNF-alpha-308 G allele overrepresented in control group and TNF-alpha-308 A allele in MwoA group. In addition, there was a significant increase of the IL-1beta+3953 T allele in MwoA cases compared with controls (P = 0.004). In conclusion, the present results indicate the possible contribution of TNF-alpha and IL-1beta gene polymorphisms to migraine headache generation in MwoA patients.

Background The International Classification of Headache Disorders provides criteria for the diagnosis and subclassification of migraine. Since there is no objective gold standard by which to test these diagnostic criteria, the criteria are based on the consensus opinion of content experts. Accurate migraine classifiers consisting of brain structural measures could serve as an objective gold standard by which to test and revise diagnostic criteria. The objectives of this study were to utilize magnetic resonance imaging measures of brain structure for constructing classifiers: 1) that accurately identify individuals as having chronic vs. episodic migraine vs. being a healthy control; and 2) that test the currently used threshold of 15 headache days/month for differentiating chronic migraine from episodic migraine. Methods Study participants underwent magnetic resonance imaging for determination of regional cortical thickness, cortical surface area, and volume. Principal components analysis combined structural measurements into principal components accounting for 85% of variability in brain structure. Models consisting of these principal components were developed to achieve the classification objectives. Ten-fold cross validation assessed classification accuracy within each of the ten runs, with data from 90% of participants randomly selected for classifier development and data from the remaining 10% of participants used to test classification performance. Headache frequency thresholds ranging from 5–15 headache days/month were evaluated to determine the threshold allowing for the most accurate subclassification of individuals into lower and higher frequency subgroups. Results Participants were 66 migraineurs and 54 healthy controls, 75.8% female, with an average age of 36 +/− 11 years. Average classifier accuracies were: a) 68% for migraine (episodic + chronic) vs. healthy controls; b) 67.2% for episodic migraine vs. healthy controls; c) 86.3% for chronic

Full Text Available Abstract Background The methylenetetrahydrofolate reductase (MTHFR gene variant C677T has been implicated as a genetic risk factor in migraine susceptibility, particularly in Migraine with Aura. Migraine, with and without aura (MA and MO have many diagnostic characteristics in common. It is postulated that migraine symptomatic characteristics might themselves be influenced by MTHFR. Here we analysed the clinical profile, migraine symptoms, triggers and treatments of 267 migraineurs previously genotyped for the MTHFR C677T variant. The chi-square test was used to analyse all potential relationships between genotype and migraine clinical variables. Regression analyses were performed to assess the association of C677T with all migraine clinical variables after adjusting for gender. Findings The homozygous TT genotype was significantly associated with MA (P P = 0.002. While the CT genotype was significantly associated with physical activity discomfort (P P = 0.002. Females with the TT genotype were significantly associated with unilateral head pain (P P P = 0.002, and the use of natural remedy for migraine treatment (P = 0.003. Conversely, male migraineurs with the TT genotype experienced higher incidences of bilateral head pain (63% vs 34% and were less likely to use a natural remedy as a migraine treatment compared to female migraineurs (5% vs 20%. Conclusions MTHFR genotype is associated with specific clinical variables of migraine including unilateral head pain, physical activity discomfort and stress.

[An encounter between medicine and astronomy: migraine visions].

Lardreau, Esther

2011-06-01

Until the second half of the eighteenth century, the very definition of migraine as hemicrania (pain felt in one side of the head) eclipsed symptoms that were then considered as "marginal", although tingling sensations, speech impairment and visual impairment had already been described by Piso and Wepfer. The possibility of a migraine without a headache nevertheless started to be envisaged, inviting one to re-evaluate the status of these phenomena. But, as paradoxical as it may seem, it is in the field of astronomy that some of these phenomena such as visual aberrations were analyzed systematically and acknowledged to be migrainous. Scintillating scotoma is no exception: it was indeed mentioned as early as in the Hippocratic corpus, but until the end of the nineteenth century it was addressed as a separate condition to migraine. We limit our study to the visual aura. Our purpose is to show that the ophthalmic symptoms affecting migraine sufferers were not, by themselves, a medical object--which somehow calls into question the very functioning of science.

Studies investigating a proposed association between multiple sclerosis (MS) and migraine have produced conflicting results and a great range in the prevalence rate of migraine in MS patients. By meta-analysing all available data we aimed to establish an overall estimate of any association in order to more accurately inform clinicians and care-givers about a potential association between MS and migraine. Pubmed and EMBASE were searched to identify suitable studies. Studies were included if they were a case-control study or cohort study in which controls were not reported to have another neurological condition, were available in English, and specified migraine as a headache sub-type. The odds ratio (OR) of migraine in MS patients vs. controls was calculated using the inverse variance with random effects model in Review Manager 5.1. Eight studies were selected for inclusion, yielding a total of 1864 MS patients and 261563 control subjects. We found a significant association between migraine and MS (OR = 2.60, 95% CI 1.12-6.04), although there was significant heterogeneity. Sensitivity analysis showed that migraine without aura was associated with MS OR = 2.29 (95% CI 1.14-4.58), with no significant heterogeneity. MS patients are more than twice as likely to report migraine as controls. Care providers should be alerted to ask MS patients about migraine in order to treat it and potentially improve quality of life. Future work should further investigate the temporal relationship of this association and relationship to the clinical characteristics of MS.

Full Text Available The aim of the present study was to examine the effect of the systematic use of comics as a literary-didactic method to reduce gender differences in reading literacy and reading motivation at the primary level of education. It was assumed that the use of comics would have a positive effect on pupils’ reading literacy and reading motivation, while also reducing the aforementioned differences between boys and girls. The dimensions of reading literacy and reading motivation were examined in experimental and control groups, before and after the intervention, by means of questionnaires and tests for pupils. The sample consisted of 143 pupils from second to fifth grade from two Slovenian primary schools in a rural environment, of which 73 pupils participated in the experimental group and 70 pupils represented the control group. Effects of the use of comics as a literary-didactic method were not found: using comics as a literary-didactic method did not have a statistically significant effect on pupils’ reading literacy and reading motivation. However, when the four-way structure of the research (taking into account the age and gender of the pupils was considered, some subgroups showed a statistically significant increase in reading interest and attitude towards reading. No reduction of gender differences in reading literacy and reading motivation was found. Based on the results, guidelines for further research are established and suggestions are offered for teachers’ work.

Throughout history, migraine-associated visual symptoms have puzzled patients, doctors, and neuroscientists. The visual aspects of migraine extend far beyond the aura phenomena, and have several clinical implications. A narrative review was conducted, beginning with migraine mechanisms, then followed by pertinent aspects of the anatomy of visual pathways, clinical features, implications of the visual system on therapy, migraine on visually impaired populations, treatment of visual auras and ocular (retinal) migraine, effect of prophylactic migraine treatments on visual aura, visual symptoms induced by anti-migraine or anti-headache drugs, and differential diagnosis. A comprehensive narrative review from both basic and clinical standpoints on the visual aspects of migraine was attained; however, the results were biased to provide any useful information for the clinician. This paper achieved its goals of addressing and condensing information on the pathophysiology of the visual aspects of migraine and its clinical aspects, especially with regards to therapy, making it useful not only for those unfamiliar to the theme but to experienced physicians as well. © 2015 American Headache Society.

Improving the attitudes of students towards science is one of the main challenges facing the teaching of the subject. The main objective of this study is to analyze the effect of students' attitudes towards science through different didactic interventions. The bibliographic search was carried out via the Web of Science database, specifically in the Education and Educational Research category, obtaining a population of 374 articles published between 2006 and 2016. We included studies with pre-experimental or quasi-experimental design that used pretest and posttest phases. Following the application of the inclusion criteria, 24 articles were selected with which a random effects meta-analysis was adopted, obtaining an average effect size of 0.54. Three moderating variables were analyzed, with a significant correlation between the type of teaching strategy and the effect of the attitude towards Science (Q = 23.17; df = 8; p educational implications are mainly due to the importance of the teaching/learning strategy used in science education in the development of positive attitudes towards the subject, and the need to increase the number of Didactic Interventions that contemplate students' attitudes towards science as a study variable is also advocated.

2010-05-01

Full Text Available It is well known that students and teachers have difficulties in learning and teaching Biochemistry due to its abstract and interconnected contents. This work proposes a didactic strategy in order to facilitate teaching and learning process in Biochemistry. The strategy was implemented with biological science undergraduate students. At first, the students were divided into groups with a specific topic to develop a game. During the semester, problem based learning cases, online activities like crossword puzzle, essay questions and educational softwares were used to present the content of each topic. The groups were oriented in classroom and online, to choose and organize contents and create ways to approach them in games. At the end of the course the groups played each other games, which were evaluated by teacher and students following some criteria like: creativity, content organization, interdisciplinarity, proposal coherence, instructions clarity, specific content. The game elaboration contributed to the development of social and cognitive functions, such as teamwork and troubleshooting, providing an interesting perspective to the student about knowledge construction process. The strategy showed up students' creativity and ability to reorganize their knowledge to a different education level. In an overview, the results indicate that the proposed didactic strategy is an effective way to enhance learning and to motivate students into Biochemistry topics.

Compared to episodic migraine patients, chronic migraineurs are more likely to be occupationally disabled, miss family activities, have comorbid anxiety and/or chronic pain disorders, and utilize significantly more health care dollars. Ziconotide is a calcium channel blocker used for the treatment of chronic severe pain without issues of tolerance or dependency found with opioid therapy. Case: A 59-year-old female had an intrathecal baclofen pump placed for spasticity secondary to multiple sclerosis. Her symptoms also included lower extremity neuropathic pain and severe migraine headaches with 22 migraine headache days per month. Prior treatments included nonsteroidal anti-inflammatory drugs, triptans, anticonvulsants, antihypertensives, and Botox injections which reduced her symptoms to four migraine days per month at best. While her spasticity had markedly improved with intrathecal baclofen, ziconotide was added to help her neuropathic pain complaints. Following initiation of low-dose ziconotide (1 µg/day, the patient noted both lower extremity pain improvement and complete resolution of migraine headaches resulting in zero migraine days per month. She has now been migraine free for 8 months. Conclusion: Upon review of the available literature, there are no published cases of migraine improvement with intrathecal ziconotide. This represents the first case describing resolution of migraine symptoms with low-dose ziconotide. Keywords: ziconotide, migraine, symptoms, chronic

Full Text Available Migraine is a pain disorder associated with abnormal brain structure and function, yet the effect of migraine on acute pain processing remains unclear. It also remains unclear whether altered pain-related brain responses and related structural changes are associated with clinical migraine characteristics. Using fMRI and three levels of thermal stimuli (non-painful, mildly painful, and moderately painful, we compared whole-brain activity between 14 migraine patients and 14 matched controls. Although, there were no significant differences in pain thresholds and pre-scan pain ratings to mildly painful thermal stimuli, patients had aberrant suprathreshold nociceptive processing. Compared to controls, patients had reduced activity in pain modulatory regions including left dorsolateral prefrontal, posterior parietal, and middle temporal cortices and, at a lower-threshold, greater activation in the right mid-insula to moderate pain versus mild pain. We also found that pain-related activity in the insula was associated with clinical variables in patients, including associations between: bilateral anterior insula and pain catastrophizing (PCS; bilateral anterior insula and contralateral posterior insula and migraine pain intensity; and bilateral posterior insula and migraine frequency at a lower-threshold. PCS and migraine pain intensity were also negatively associated with activity in midline regions including posterior cingulate and medial prefrontal cortices. Diffusion tensor imaging revealed a negative correlation between fractional anisotropy (a measure of white matter integrity; FA and migraine duration in the right mid-insula and a positive correlation between left mid-insula FA and PCS. In sum, while patients showed lower sensitivity to acute noxious stimuli, the neuroimaging findings suggest enhanced nociceptive processing and significantly disrupted modulatory networks, particularly involving the insula cortex, associated with indices of

Anxiety and mood disorders have been shown to be the most relevant psychiatric comorbidities associated with migraine, influencing its clinical course, treatment response, and clinical outcomes. Limited information is available on how specific anxiety and depression symptoms are related to migraine. Symptoms-based approach, a current trend in mental health research, may improve our understanding in migraine comorbidity. The purpose of this study was to analyze how anxiety and depression aspects are related to migraine through a symptom-based approach. We studied 782 patients from the general population who completed a self-administered questionnaire assessing demographics, headache features, anxiety and depression symptoms. A binary logistic regression analyses were conducted to test the association between all four ratings in GAD-7 (anxiety) and PHQ-9 (depression) scales subitems as covariates, and migraine vs no headache as the outcome. The leading Odd Ratios (OR) observed in individuals with migraine relative to those without migraine were anxiety related, "Not being able to stop or control worrying" on a daily basis [OR (CI 95%)] 49.2 (13.6-178.2), "trouble relaxing" 25.7 (7.1-92.6), "Feeling nervous, anxious or on edge" on a daily basis 25.4 (6.9-93.8), and "worrying too much about different things" 24.4 (7.7-77.6). Although the hallmark symptoms of depression are emotional (hopelessness and sadness), the highest scores found were physical: apetite, fatigue, and poor sleep. Irritability had a significant increase in migraine risk [OR 3.8 (1.9-7.8) if experienced some days, 7.5 (2.7-20.7) more than half the days, and 22.0 (5.7-84.9) when experienced nearly every day]. Anxiety was more robustly associated with increase in migraine risk than depression. Lack of ability to properly control worrying and to relax are the most prominent issues in migraine psychiatric comorbidity. Physical symptoms in depression are more linked to migraine than emotional symptoms. A

Full Text Available Migraine is a disorder that has debilitating pain, and affects all aspects of life, including the academic, social, and family life of patients. In addition, studies show the effects of migraine on patient's relationships with family members such as spouse, children, and other family members. In addition to physical pain, migraines are tied to significant psychological and economic costs. Migraineurs tend to have high levels of depression and anxiety, and migraine headaches have a profoundly negative impact on sufferers’ quality of life. In the present research, we investigated the correlations and regressions of cognitive, personality, and family factors with migraine headache, to find predictor factors of migraine. In this study, the following questionnaires were used: For migraine: six-item Headache Impact Test (HIT-6, and Specific Quality of Life Questionnaire Version 2.1.; for cognitive factors: Irrational Beliefs Test and Dysfunctional Attitudes Scale; for personality factors: NEO Personality Inventory; and for family factors: Family Assessment Device. This project was on 58 women with migraine headaches, diagnosed by neurologist. The findings show that, there is a significant regression between cognitive, personality, and family factors and HIT-6. In cognitive factors, frustration reactivity and anxious overconcern, in personality factors, extraversion trait, and in family factors, affective involvement are significant. Moreover, there is a significant regression between cognitive, personality, and family factors and MSQ. In cognitive factors, frustration reactivity, anxious overconcern, and helplessness, in personality factors, agreeableness and consciousness, and in family factors, affective involvement and general functioning are significant. This project showed that cognitive, personality, and family factors have a correlation with migraine headache.
