There is re-emerging interest in community health workers (CHWs) as part of wider policies regarding task-shifting within human resources for health. This paper examines the history of CHW programmes established in South Africa in the later apartheid years (1970s–1994) – a time of innovative initiatives. After 1994, the new democratic government embraced primary healthcare (PHC), however CHW initiatives were not included in their health plan and most of these programmes subsequently collapsed. Since then a wide array of disease-focused CHW projects have emerged, particularly within HIV care.

Thirteen oral history interviews and eight witness seminars were conducted in South Africa in April 2008 with founders and CHWs from these earlier programmes. These data were triangulated with written primary sources and analysed using thematic content analysis. The study suggests that 1970s–1990s CHW programmes were seen as innovative, responsive, comprehensive and empowering for staff and communities, a focus which respondents felt was lost within current programmes. The growth of these earlier projects was underpinned by the struggle against apartheid. Respondents felt that the more technical focus of current CHW programmes under-utilise a valuable human resource which previously had a much wider social and health impact. These prior experiences and lessons learned could usefully inform policy-making frameworks for CHWs in South Africa today.

Objectives. In 2007 neonatal screening (NNS) was expanded to include screening for sickle cell disease (SCD) and beta-thalassaemia. Up until that year no formal recommendations for haemoglobinopathy (carrier) screening existed in the Netherlands. Although it has been subject to debate in the past, preconceptional and prenatal haemoglobinopathy carrier screening are not part of routine healthcare in the Netherlands. This study aimed to explore the decision-making process of the past: why was the introduction of a screening programme for haemoglobinopathy considered to be untimely, and did ethnicity play a role given the history in other countries surrounding the introduction of haemoglobinopathy screening?

Design. A witness seminar was organised, inviting key figures to discuss the decision-making process concerning haemoglobinopathy screening in the Netherlands, thereby adding new perspectives on past events. The transcript was content-analysed.

Results. The subject of haemoglobinopathy screening first appeared in the 1970s. As opposed to a long history of neglect of African-American health in the United States, the heritage of the Second World War influenced the decision-making process in the Netherlands. As a consequence, registration of ethnicity surfaced as an impeding factor. However, overall, official Dutch screening policy was restrained regarding reproductive issues caused by fear of eugenics. In the 1990s haemoglobinopathy screening was found to be ‘not opportune’ due to low prevalence, lack of knowledge and fear of stigmatisation. Currently the registration of ethnicity remains on the political agenda, but still proves to be a sensitive subject.

Discussion. Carrier screening in general never appeared high on the policy agenda. Registration of ethnicity remains sensitive caused by the current political climate. Complexities related to carrier screening are a challenge in Dutch healthcare. Whether carrier screening will be considered a valuable complementary strategy in the Netherlands, depends partly on participation of representatives of high-risk groups in policy making.

Background:

Sleep is a very vital physiological mechanism, which involves complex interactions in the nervous system. These interactions are not well understood and have been a subject of controversy in contemporary medical practice.

Objectives:

To review of the neurophysiological factors in the subject of sleep, and recent research findings that forms the basis for the current knowledge on sleep.

Methods:

Information sources consulted included, published works of past researchers, current articles on sleep in conference papers, recent editions of textbooks on neuroscience, articles in seminar papers, reports extracted from newspaper and magazine articles on sleep, reports accessed from the Internet using Google Search Engines and lecture notes.

Results:

It was noted that emphasis has now shifted from the concept that sleep was predominantly the product of activities in the neural systems in phylogenetically old reticular core of the brain through withdrawal of sensory input, to emphasis on the role of neurotransmitter systems, especially - Ach, serotonin and GABA. This review also noted that, among others, emphasis is further shifting to the PGO waves which is fast gaining prominence as the mechanism involved in the production of REM sleep and dreams in particular.

Conclusion:

It became obvious from this review, that full knowledge of the neurophysiological processes involved in sleep production appear generally to still be more of speculative, and are yet far from full understanding.

Background

Many medical schools have embraced small group learning methods in their undergraduate curricula. Given increasing financial constraints on universities, active learning groups like seminars (with 25 students a group) are gaining popularity. To enhance the understanding of seminar learning and to determine how seminar learning can be optimised it is important to investigate stakeholders’ views. In this study, we qualitatively explored the views of teachers on aspects affecting seminar learning.

Methods

Twenty-four teachers with experience in facilitating seminars in a three-year bachelor curriculum participated in semi-structured focus group interviews. Three focus groups met twice with an interval of two weeks led by one moderator. Sessions were audio taped, transcribed verbatim and independently coded by two researchers using thematic analysis. An iterative process of data reduction resulted in emerging aspects that influence seminar learning.

Results

Teachers identified seven key aspects affecting seminar learning: the seminar teacher, students, preparation, group functioning, seminar goals and content, course coherence and schedule and facilities. Important components of these aspects were: the teachers’ role in developing seminars (‘ownership’), the amount and quality of preparation materials, a non-threatening learning climate, continuity of group composition, suitability of subjects for seminar teaching, the number and quality of seminar questions, and alignment of different course activities.

Conclusions

The results of this study contribute to the unravelling of the ‘the black box’ of seminar learning. Suggestions for ways to optimise active learning in seminars are made regarding curriculum development, seminar content, quality assurance and faculty development.

An International Medicine Elective Seminar Course at the New Jersey Medical School (NJMS) was designed in 1985 to present a description of medical education, medical care systems, major global health problems, and intervention programs in other countries. Seminars are scheduled for nine weeks in the fall semester. At the end of each course, the medical students complete evaluations. Almost all (97%) students in 1997-1998 evaluated the course as either good (55%) or excellent (45%). Enrollment in the International Medicine Seminar Course increased from 12 medical students in 1985-1986 to 62 students in 1997-1998. An increasing number of students have applied for a fourth-year overseas International Medicine Elective. This and students' evaluations indicated that they have been motivated toward international medicine. The atmosphere of informal seminars and faculty interaction with students has characterized the course. It has made this model of teaching an ideal forum for medical students' professional growth. This course offers students the opportunity and insight to explore facets of their professional role not explicitly covered in the formal medical curriculum. The International Medicine Seminar Course is a self-supported model and can be adopted readily by other medical schools.

KIST Medical College is a new medical school in Lalitpur, Nepal. In Nepal, six basic science subjects are taught together in an integrated organ system-based manner with early clinical exposure and community medicine. Correlation seminars are conducted at the end of covering each organ system. The topics are decided by the core academic group (consisting of members from each basic science department, the Department of Community Medicine, the academic director, and the clinical and program coordinators) considering the public health importance of the condition and its ability to include learning objectives from a maximum number of subjects. The learning objectives are decided by individual departments and finalized after the meeting of the core group. There are two student coordinators for each seminar and an evaluation group evaluates each seminar and presenter. Correlation seminars help students revise the organ system covered and understand its clinical importance, promote teamwork and organization, and supports active learning. Correlation seminars should be considered as a learning modality by other medical schools.

Introduction

Although medical educational debt continues to escalate, residents receive little guidance in financial planning.

Aim

To educate interns about long-term investment strategies.

Setting

University-based medicine internship program.

Program Description

An unselected cohort of interns (n = 52; 84% of all interns) underwent a 90-minute interactive seminar on personal finance, focusing on retirement savings. Participants completed a preseminar investor literacy test to assess baseline financial knowledge. Afterward, interns rated the seminar and expressed their intention to make changes to their long-term retirement accounts. After 37 interns had attended the seminar, a survey was administered to all interns to compare actual changes to these accounts between seminar attendees and nonattendees.

Measurements and Main Results

Interns’ average score on the investor literacy test was 40%, equal to the general population. Interns strongly agreed that the seminar was valuable (average 5.0 on 5-point Likert scale). Of the 46 respondents to the account allocation survey, interns who had already attended the seminar (n = 25) were more likely than interns who had not yet attended (n = 21) to have switched their investments from low to high-yield accounts at the university hospital (64 vs 19%, P = 0.003) and to enroll in the county hospital retirement plan (64 vs 33%, P = 0.07).

Conclusions

One 90-minute seminar on personal finances leads to significant changes in allocation of tax-deferred retirement savings. We calculate that these changes can lead to substantial long-term financial benefits and suggest that programs consider automatically enrolling trainees into higher yield retirement plans.

Contemporary Western medicine has witnessed a fragmentation of our conceptualization of the medical endeavor into ‘traditional medicine’ and ‘non-traditional medicine’. The former is meant to refer to the Western medical tradition, the latter encompasses both ‘complementary’ and ‘alternative’ medical practices. Complementary medicine complements conventional medical treatments, and alternative modes of medical interventions are meant to replace traditional Western medicine. Evidence-based research must be directed at establishing the best available evidence in complementary and alternative medicine. This paper is the first of a set of four ‘lectures’ that reviews the process of evidence-based research, and discusses its implications and applications for the early decades of the 21st century. The purpose of this paper is to introduce the series by examining some of the historical and philosophical foundations of this research endeavor.

The monoclonal antibody market continues to witness an impressive rate of growth and has become the leading source of expansion in the biologic segment within the pharmaceutical industry. Currently marketed monoclonal antibodies target a diverse array of antigens. These antigens are distributed in a variety of tissues such as tumors, lungs, synovial fluid, psoriatic plaques, and lymph nodes. As the concentration of drug at the proximity of the biological receptor determines the magnitude of the observed pharmacological responses, a significant consideration in effective therapeutic application of monoclonal antibodies is a thorough understanding of the processes that regulate antibody biodistribution. Monoclonal antibody distribution is affected by factors such as molecular weight, blood flow, tissue and tumor heterogeneity, structure and porosity, target antigen density, turnover rate, and the target antigen expression profile.

Objectives

To implement and evaluate an innovative approach to a pharmacy seminar course intended to develop students' presentation skills and encourage them to think critically about contemporary pharmacy issues.

Design

The instructor provided lectures intended to prepare students for their presentations. These lectures included tips on writing abstracts, learning objectives, use of visual aids, and presentation delivery. Pairs of students chose a pharmacy issue, researched their topic including identifying various strengths of evidence to support a perspective, wrote an abstract and learning objectives, prepared their visual aids, and delivered a pro/con perspective. Students also provided peer evaluations for these presentations. A personal response system was used to provide class input on the presentations.

Assessment

Ninety-five percent of the peer evaluations of the presentations were good to excellent. The overall course evaluations indicated achievement of course goals.

Conclusions

A pharmacy seminar course intended to develop student presentation skills and critical thinking about contemporary pharmacy issues was demonstrated to be successful. The “taking sides” format was an effective design for accomplishing these objectives.

Background

Little data exist for the effectiveness of communication skills teaching for medical students in non-English speaking countries. We conducted a non-randomized controlled study to examine if a short intensive seminar for Japanese medical students had any impact on communication skills with patients.

Methods

Throughout the academic year 2001–2002, a total of 105 fifth-year students (18 groups of 5 to 7 students) participated, one group at a time, in a two-day, small group seminar on medical interviewing. Half way through the year, a five-station objective structured clinical examination (OSCE) was conducted for all fifth-year students. We videotaped all the students' interaction with a standardized patient in one OSCE station that was focused on communication skills. Two independent observers rated the videotapes of 50 students who had attended the seminar and 47 who had not. Sixteen core communication skills were measured. Disagreements between raters were resolved by a third observer's rating.

Results

There was a statistically significant difference in proportions of students who were judged as 'acceptable' in one particular skill related to understanding patient's perspectives: asking how the illness or problems affected the patient's life, (53% in the experimental group and 30% in the control group, p = .02). No differences were observed in the other 15 core communication skills, although there was a trend for improvement in the skill for asking the patient's ideas about the illness or problems (60% vs. 40%, p = .054) and one of the relationship building skills; being attentive and empathic nonverbally (87% vs. 72%, p = .064).

Conclusion

The results of this study suggest that a short, intensive small group seminar for Japanese medical students may have had a short-term impact on specific communication skills, pertaining to understanding patient's perspectives.

As the 21st century dawns, I reflect on the history of humankind with growing concern about the need to understand the underlying biological and cultural roots of ethnic conflict and warfare. In the many studies of human conflict, innate biological predispositions have been neglected. This article is the third part of a series of seminars for medical residents at the University of Texas Southwestern Medical School at Dallas (see http://adarwinstudygroup.org/). The series starts with in-depth coverage of Darwinian natural and sexual selection, with examples from the domestication of animals and plants and the crisis of antibiotic resistance. The series strives to show how biology has been neglected in the study of the we-they orientation of human behavior, with its devastating consequences. The subject material is profoundly disturbing, as it looks at “human nature” and contrasts the “dark side” of human behavior with the opposite, profoundly caring and loving side.

Background

The inaccuracy of death certification can lead to the misallocation of resources in health care programs and research. We evaluated the rate of errors in the completion of death certificates among medical residents from various specialties, before and after an educational intervention which was designed to improve the accuracy in the certification of the cause of death.

Methods

A 90-min seminar was delivered to seven mixed groups of medical trainees (n = 166) from several health care institutions in Spain. Physicians were asked to read and anonymously complete a same case-scenario of death certification before and after the seminar. We compared the rates of errors and the impact of the educational intervention before and after the seminar.

Results

A total of 332 death certificates (166 completed before and 166 completed after the intervention) were audited. Death certificates were completed with errors by 71.1% of the physicians before the educational intervention. Following the seminar, the proportion of death certificates with errors decreased to 9% (p < 0.0001). The most common error in the completion of death certificates was the listing of the mechanism of death instead of the cause of death. Before the seminar, 56.8% listed respiratory or cardiac arrest as the immediate cause of death. None of the participants listed any mechanism of death after the educational intervention (p < 0.0001).

Conclusion

Major errors in the completion of the correct cause of death on death certificates are common among medical residents. A simple educational intervention can dramatically improve the accuracy in the completion of death certificates by physicians.

Noroviruses are the principal cause of epidemic gastroenteritis worldwide with GII.4 strains accounting for 80% of infections. The major capsid protein of GII.4 strains is evolving rapidly, resulting in new epidemic strains with altered antigenic potentials. To test if antigenic drift may contribute to GII.4 persistence, human memory B cells were immortalized and the resulting human monoclonal antibodies (mAbs) characterized for reactivity to a panel of time-ordered GII.4 virus-like particles (VLPs). Reflecting the complex exposure history of the volunteer, human anti-GII.4 mAbs grouped into three VLP reactivity patterns; ancestral (1987–1997), contemporary (2004–2009), and broad (1987–2009). NVB 114 reacted exclusively to the earliest GII.4 VLPs by EIA and blockade. NVB 97 specifically bound and blocked only contemporary GII.4 VLPs, while NBV 111 and 43.9 exclusively reacted with and blocked variants of the GII.4.2006 Minerva strain. Three mAbs had broad GII.4 reactivity. Two, NVB 37.10 and 61.3, also detected other genogroup II VLPs by EIA but did not block any VLP interactions with carbohydrate ligands. NVB 71.4 cross-neutralized the panel of time-ordered GII.4 VLPs, as measured by VLP-carbohydrate blockade assays. Using mutant VLPs designed to alter predicted antigenic epitopes, two evolving, GII.4-specific, blockade epitopes were mapped. Amino acids 294–298 and 368–372 were required for binding NVB 114, 111 and 43.9 mAbs. Amino acids 393–395 were essential for binding NVB 97, supporting earlier correlations between antibody blockade escape and carbohydrate binding variation. These data inform VLP vaccine design, provide a strategy for expanding the cross-blockade potential of chimeric VLP vaccines, and identify an antibody with broadly neutralizing therapeutic potential for the treatment of human disease. Moreover, these data support the hypothesis that GII.4 norovirus evolution is heavily influenced by antigenic variation of neutralizing epitopes and consequently, antibody-driven receptor switching; thus, protective herd immunity is a driving force in norovirus molecular evolution.

Author Summary

Noroviruses are the principal cause of epidemic gastroenteritis worldwide with GII.4 strains accounting for 80% of infections. The major capsid protein of GII.4 strains is evolving rapidly, resulting in new epidemic strains with altered antigenic sites. To define these sites we prepared the first human monoclonal antibodies (Hu mAbs) against GII.4 noroviruses by immortalizing memory B cells and characterizing antibody reactivity and carbohydrate blockade responses across a ∼20 year panel of time-ordered GII.4 virus-like particles (VLPs). Reflecting the complex exposure history of the patient, human anti-GII.4 mAbs grouped into three VLP reactivity patterns: broad (1987–2009), contemporary (2004–2009), and ancestral (1987–2002). We also identified the location of several defined epitopes which evolve over time and drive antigenic change. Our data indicate that antibodies targeting these sites block carbohydrate binding and likely select for the emergence of new strains that escape herd immunity and recognize unique carbohydrates for entry, resulting in new outbreaks of disease in vulnerable human populations. Importantly, these studies critically inform the rational design of broadly active vaccines and immunotherapeutics for the treatment of norovirus disease.

Background

Learning in small group tutorials is appreciated by students and effective in the acquisition of clinical problem-solving skills but poses financial and resource challenges. Interactive seminars, which accommodate large groups, might be an alternative. This study examines the educational effectiveness of small group tutorials and interactive seminars and students' preferences for and satisfaction with these formats.

Methods

Students in year three of the Leiden undergraduate medical curriculum, who agreed to participate in a randomized controlled trial (RCT, n = 107), were randomly allocated to small group tutorials (n = 53) or interactive seminars (n = 54). Students who did not agree were free to choose either format (n = 105). Educational effectiveness was measured by comparing the participants' results on the end-of-block test. Data on students' reasons and satisfaction were collected by means of questionnaires. Data was analyzed using student unpaired t test or chi-square test where appropriate.

Results

There were no significant differences between the two educational formats in students' test grades. Retention of knowledge through active participation was the most frequently cited reason for preferring small group tutorials, while a dislike of compulsory course components was mentioned more frequently by students preferring interactive seminars. Small group tutorials led to greater satisfaction.

Conclusions

We found that small group tutorials leads to greater satisfaction but not to better learning results. Interactive learning in large groups might be might be an effective alternative to small group tutorials in some cases and be offered as an option.

Physicians may find serving as an expert witness to be interesting, intellectually stimulating, and financially beneficial. However, potential expert witnesses should be aware of the increased legal scrutiny being applied to expert witness testimony in medical malpractice litigation. In the past, expert witnesses received absolute immunity from civil litigation regarding their testimony. This is no longer the case. Expert witnesses may be subject to disciplinary sanctions from professional organizations and state medical boards. In addition, emerging case law is defining the legal duty owed by the expert witness to the litigating parties. Orthopaedic surgeons who serve as expert witnesses should be familiar with the relevant Standards of Professionalism issued by the American Academy of Orthopaedic Surgeons.

The eclectic problem solving methodology used by the British Medical Association (BMA) is described in this paper. It has grown from the daily need to respond to doctors' practical queries and incorporates reference to law, traditional professional codes, and established BMA policies—all of which must be regularly assessed against the benchmark of contemporary societal expectations. The two Jehovah's Witness scenarios are analysed, using this methodology and in both cases the four principles solution is found to concur with that of the BMA's approach. The author's overall conclusion is that although the BMA resorts to a lengthier list of thins to consider, the solutions that emerge are often likely to coincide with the four principles approach.

Background

The last decade has witnessed a rapid transformation in the role boundaries of the allied health professions, enabled through the creation of new roles and the expansion of existing, traditional roles. A strategy of health care 'modernisation' has encompassed calls for the redrawing of professional boundaries and identities, linked with demands for greater workforce flexibility. Several tasks and roles previously within the exclusive domain of medicine have been delegated to, or assumed by, allied health professionals, as the workforce is reshaped to meet the challenges posed by changing demographic, social and political contexts. The prescribing of medicines by non-medically qualified healthcare professionals, and in particular the podiatry profession, reflects these changes.

Methods

Using a range of key primary documentary sources derived from published material in the public domain and unpublished material in private possession, this paper traces the development of contemporary UK and Australasian podiatric prescribing, access, supply and administration of medicines. Documentary sources include material from legislative, health policy, regulatory and professional bodies (including both State and Federal sources in Australia).

Results

Tracing a chronological, comparative, socio-historical account of the emergence and development of 'prescribing' in podiatry in both Australasia and the UK enables an analysis of the impact of health policy reforms on the use of, and access to, medicines by podiatrists. The advent of neo-liberal healthcare policies, coupled with demands for workforce flexibility and role transfer within a climate of demographic, economic and social change has enabled allied health professionals to undertake an expanding number of tasks involving the sale, supply, administration and prescription of medicines.

Conclusion

As a challenge to medical dominance, these changes, although driven by wider healthcare policy, have met with resistance. As anticipated in the theory of medical dominance, inter-professional jurisdictional disputes centred on the right to access, administer, supply and prescribe medicines act as obstacles to workforce change. Nevertheless, the broader policy agenda continues to ensure workforce redesign in which podiatry has assumed wider roles and responsibilities in prescribing.

Background

Sudden cardiac death (SCD) remains a major public health problem; however, its true burden remains unknown with widely variable estimates of its incidence. We aimed to examine the contemporary epidemiology and autopsy characteristics of SCD in an ethnically diverse community.

Methods

3 physicians reviewed all deaths age ≥ 20 years reported to the San Francisco Medical Examiner (ME) in 2007 for presentations fitting WHO SCD criteria -- within 1 hour of symptom onset (witnessed) or within 24 hours of being observed alive and symptom-free (unwitnessed). After comprehensive review of ME investigation, WHO SCDs were classified as sudden arrhythmic death (SAD) or non-arrhythmic death. Coronary artery disease (CAD) and cardiac mass were evaluated in all SADs undergoing autopsy and compared to demographically similar accidental trauma control deaths.

Results

We identified 252 WHO SCDs; 145 were SADs. Men had a 2.2-fold higher SAD rate (p<0.0005). Blacks had a 3.15-fold higher SAD rate compared to Caucasians (p = 0.003). Significant CAD was present in 38.9% of SADs and associated with higher SAD risk compared to control deaths (OR 2.58, 95% CI 1.12–5.97, p=0.026). Mean cardiac mass was linearly associated with risk for SAD in cases without significant CAD (OR 2.06 per 100g, 95% CI 1.43–2.98, p<0.0005).

Conclusions

In a diverse, urban population, SAD incidence varied substantially by gender and race. Significant CAD accounted for far fewer SADs than previous studies, but remained associated with a 2.6-fold higher risk as compared to control deaths. These findings may reflect the evolving contemporary epidemiology of SCD.

Headache is one of the most common manifestations of non-traumatic intracranial hemorrhage, which is an uncommon, but not rare, cause of cardiac arrest in adults. History of a sudden headache preceding collapse may be a helpful clue to estimate the cause of out-of-hospital cardiac arrest (OHCA). Medical records of witnessed OHCA patients were reviewed to identify those who complained of a sudden headache preceding collapse, and the incidence of intracranial hemorrhage among them as well as their clinical characteristics was investigated retrospectively. During the 12-month period, 124 patients who sustained a witnessed OHCA were treated. Among them, 74 (60%) collapsed without any pain complaint, and only 6 (5%) complained of a sudden headache preceding collapse. All of the six patients were resuscitated: four had a severe subarachnoid hemorrhage (SAH), while the other two had a massive cerebellar hemorrhage. By contrast, 39 of the 74 patients who collapsed without any pain were resuscitated. Among them, another six patients were found to harbor an SAH. Thus, a total of 12 among the 124 witnessed OHCA (10%) sustained a fatal intracranial hemorrhage. While OHCA patients who collapse complaining of a sudden headache are uncommonly seen in the emergency room, they have a high likelihood of harboring a severe intracranial hemorrhage. It should also be reminded that approximately half of patients whose cardiac arrest is due to an intracranial hemorrhage may collapse without complaining of a headache. The prognosis of those with cerebral origin of OHCA is invariably poor, although they may relatively easily be resuscitated temporarily. Focus needs to be directed to avoid sudden death from a potentially treatable cerebral lesion, and public education to promote the awareness for the symptoms of potentially lethal hemorrhagic stroke is warranted.

Since 1974 the National Health Service (NHS) has been subject to successive reorganisations which have shaped and reshaped patterns of administration, clinical care and services. This paper uses two sources of oral evidence: a Witness Seminar with a group of administrators who attended the NHS National Administrators’ Training Scheme in the late 1950s and a collection of interviews with doctors and managers who have played key roles in the health services of Manchester and Salford between 1974 and 2007. It surveys the day-to-day interactions between doctors and administrators/managers in hospital settings and analyses what these reveal about relationships within the broader context of shifting organisational structures and management styles. It suggests that the evidence challenges the historical stereotyping of the two groups and that strong working relationships have been determined as much by the values of respect and association as by changes to structures or management styles.

INTRODUCTION:

Dermatological disorders are common in medical practice. In medical school, however, the time devoted to teaching dermatology is usually very limited. Therefore, online educational systems have increasingly been used in medical education settings to enhance exposure to dermatology.

OBJECTIVE:

The present study was designed to develop an e-learning program for medical students in dermatology and evaluate the impact of this program on learning.

METHODS:

This prospective study included second year medical students at the University of Technology and Science, Salvador, Brazil. All students attended discussion seminars and practical activities, and half of the students had adjunct online seminars (blended learning). Tests were given to all students before and after the courses, and test scores were evaluated.

RESULTS:

Students who participated in online discussions associated with face-to-face activities (blended learning) had significantly higher posttest scores (9.0±0.8) than those who only participated in classes (7.75±1.8, p <0.01).

CONCLUSIONS:

The results indicate that an associated online course might improve the learning of medical students in dermatology.

This study examined whether witnessed community and parental violence represented risk factors for substance use and delinquency among adolescents, beyond the contribution of direct violence and other risk factors. We also examined the role of violence characteristics. Participants were a national sample of 3,614 adolescents. Structured telephone interviews assessed demographics, trauma history, witnessed violence, delinquency, and substance use. While accounting for trauma history and other risk factors, witnessed community and parental violence were associated with delinquency. Community violence was associated with substance use. Chronic violence, knowing the perpetrator, and violence outside of school were correlated with substance use and delinquency among adolescents who witnessed community violence. These findings highlight the importance of targeting witnessed violence in prevention and intervention efforts.

The recent years have witnessed great efforts in establishing new therapeutic options for multiple sclerosis (MS), especially for relapsing–remitting disease courses. In particular, the application of monoclonal antibodies provide innovative approaches allowing for blocking or depleting specific molecular targets, which are of interest in the pathogenesis of MS. While natalizumab received approval by the US Food and Drug Administration and the European Medicines Agency in 2006 as the first monoclonal antibody in MS therapy, rituximab, alemtuzumab, and daclizumab were successfully tested for relapsing-remitting MS in small cohorts in the meantime. Here, we review the data available from these recent phase II trials and at the same time critically discuss possible pitfalls which may be relevant for clinical practice. The results of these studies may not only broaden our therapeutic options in the near future, but also provide new insights into disease pathogenesis.
