This paper explores the potential for wiki-type open architecture software to promote and support collaborative learning through the use of student-created content. It delineates some of the affordances and constraints of wiki software as an open architecture that has the potential to facilitate collaborative learning through community-focused enquiry. It seeks to promote debate in this key area of development, and highlights some recent key contributions to the developing discourse on social software in what has been termed ‘the architecture of participation’.

This hybrid review-case study introduces three-dimensional (3-D) virtual worlds and their educational potential to medical/health librarians and educators. Second life ( ) is perhaps the most popular virtual world platform in use today, with an emphasis on social interaction. We describe some medical and health education examples from Second Life, including Second Life Medical and Consumer Health Libraries (Healthinfo Island—funded by a grant from the US National Library of Medicine), and VNEC (Virtual Neurological Education Centre—developed at the University of Plymouth, UK), which we present as two detailed ‘case studies’. The pedagogical potentials of Second Life are then discussed, as well as some issues and challenges related to the use of virtual worlds. We have also compiled an up-to-date resource page ( ), with additional online material and pointers to support and extend this study. [ABSTRACT FROM AUTHOR]

Web 2.0 sociable technologies and social software are presented as enablers in health and health care, for organizations, clinicians, patients and laypersons. They include social networking services, collaborative filtering, social bookmarking, folksonomies, social search engines, file sharing and tagging, mashups, instant messaging, and online multi-player games. The more popular Web 2.0 applications in education, namely wikis, blogs and podcasts, are but the tip of the social software iceberg. Web 2.0 technologies represent a quite revolutionary way of managing and repurposing/remixing online information and knowledge repositories, including clinical and research information, in comparison with the traditional Web 1.0 model. The paper also offers a glimpse of future software, touching on Web 3.0 (the Semantic Web) and how it could be combined with Web 2.0 to produce the ultimate architecture of participation. Although the tools presented in this review look very promising and potentially fit for purpose in many health care applications and scenarios, careful thinking, testing and evaluation research are still needed in order to establish ‘best practice models’ for leveraging these emerging technologies to boost our teaching and learning productivity, foster stronger ‘communities of practice’, and support continuing medical education/professional development (CME/CPD) and patient education.

Six migraine patients experienced significant topiramate-related cognitive and language dysfunction that improved with donepezil treatment and allowed uninterrupted topiramate use. These patients represent the first report of topiramate-related cognitive and language dysfunction that improved with a cholinesterase inhibitor. Although, the mechanism responsible for this effect is uncertain, cholinesterase inhibition resulting in cholinergic augmentation and enhanced cognition probably account for some if not most of the improvement.

The article discusses the reasons and ill-effects of misdiagnosis of migraine or pseudosinus headaches by migraineurs and physicians in the U.S. More than 50 percent of people with migraine have absolutely no idea that they have migraine, nor do their physicians. Instead, sinus headache, tensiontype headache, and stress headache are diagnosed far too frequently. The frequent misdiagnosis of a frequently occurring disorder, produces considerable confusion, suffering, delayed treatment, and alienation from appropriate health care. Migraine is a benign, recurrent headache with environmental sensitivities, nausea, and disability. To reduce migraine misdiagnosis will require attitudes to change, and to change attitudes, educators must offer effective educational experiences that communicate the prevalence and negative social impact of migraine.

A letter to the editor in response to the article "Changing physician knowledge, attitudes, and beliefs about migraine: Evaluation of a new educational intervention," by M.B. Patwardhan and colleagues in a 2006 issue is presented.
