Objectives Image-guided musculoskeletal interventional procedures around the hip are widely used in daily clinical practice. The need for clarity concerning the actual added value of imaging guidance and types of medications to be offered led the Ultrasound and the Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) to promote, with the support of its Research Committee, a collaborative project to review the published literature on image-guided musculoskeletal interventional procedures in the lower limb in order to derive a list of clinical indications. Methods In this article, we report the results of a Delphi-based consensus of 53 experts who reviewed the published literature for evidence on image-guided interventional procedures offered in the joint and soft tissues around the hip in order of their clinical indications. Results Ten statements concerning image-guided treatment procedures around the hip have been collected by the panel of ESSR experts. Conclusions This work highlighted that there is still low evidence in the existing literature on some of these interventional procedures. Further large prospective randomized trials are essential to better confirm the benefits and objectively clarify the role of imaging to guide musculoskeletal interventional procedures around the hip.

Objectives To perform a Delphi-based consensus on published evidence on image-guided interventional procedures for peripheral nerves of the lower limb (excluding Morton’s neuroma) and provide clinical indications. Methods We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around peripheral nerves in the lower limb (excluding Morton’s neuroma) to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper. Results Nine statements on image-guided interventional procedures for peripheral nerves of the lower limb have been drafted. All of them received strong consensus. Image-guided pudendal nerve block is safe, effective, and well tolerated with few complications. US-guided perisciatic injection of anesthetic provides good symptom relief in patients with piriformis syndrome; however, the addition of corticosteroids to local anesthetics still has an unclear role. US-guided lateral femoral cutaneous nerve block can be used to provide effective post-operative regional analgesia. Conclusion Despite the promising results reported by published papers on image-guided interventional procedures for peripheral nerves of the lower limb, there is still a lack of evidence on the efficacy of most procedures.

Objectives Interventional procedures around the knee are widely adopted for treating different musculoskeletal conditions. A panel of experts from the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the existing literature to assess the evidence on image-guided musculoskeletal interventional procedures around the knee, with the goal of highlighting some controversies associated with these procedures, specifically the role of imaging guidance, as well as the efficacy of the medications routinely injected. Methods We report the results of a Delphi-based consensus of 53 experts in musculoskeletal radiology, who reviewed the published literature for evidence on image-guided interventional procedures around the knee to derive a list of pertinent clinical indications. Results A list of 10 statements about clinical indications of image-guided procedures around the knee was created by a Delphi-based consensus. Only two of them had the highest level of evidence; all of them received 100% consensus. Conclusions Ultrasonography guidance is strongly recommended for intra-articular and patellar tendinopathy procedures to ensure the precision and efficacy of these treatments. Prospective randomized studies remain warranted to better understand the role of imaging guidance and assess some of the medications used for interventional procedures around the knee.

Objectives Clarity regarding accuracy and effectiveness for interventional procedures around the foot and ankle is lacking. Consequently, a board of 53 members of the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the published literature to evaluate the evidence on image-guided musculoskeletal interventional procedures around this anatomical region. Methods We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around foot and ankle in order to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper that was shared with all panel members for final approval. Results A list of 16 evidence-based statements on clinical indications for image-guided musculoskeletal interventional procedures in the foot and ankle were drafted after a literature review. The highest level of evidence was reported for four statements, all receiving 100% agreement. Conclusion According to this consensus, image-guided interventions should not be considered a first-level approach for treating Achilles tendinopathy, while ultrasonography guidance is strongly recommended to improve the efficacy of interventional procedures for plantar fasciitis and Morton’s neuroma, particularly using platelet-rich plasma and corticosteroids, respectively.

In this paper, we explore an interaction between a competitive “Counter Strike: Global Offensive” player and her younger brother, whom she is tutoring in his first match in competitive mode. At least two phenomena, intertwined with each other, are prominent in this data excerpt. One is the boy’s consistent orientation to his sister’s instructions, accountable and observable through the work of following them. The other one deals with the intricacies and overlaps of Lebenswelt (life-world) and Spielwelt (game-world) time and how these apparently different temporalities constitute a temporal whole. Analysis suggests that communication in this instructional setting is grounded in gestalt-contextures that embrace multiple embodied forms of interaction such as talk, gesture, gaze, as well as in-game elements (such as rules to follow and goals to achieve), and how important is the re-specification of those elements as a set, not as a mere sum of individual pieces. Moreover, it is discussed how, while in a gameplay context, players use their common-sense reasoning and practices to elaborate strategies and develop skills necessary to successfully reach their goals.

Given the growth in usage of online social networks, such as Facebook, YouTube, Instagram and Snapchat, which rely on videos and images (such as photos) to relay information between connections, new intuitive languages, though not yet formally recognized, have emerged. We also herein give the example of a new language we have created - the Business Narrative Modelling Language (BNML) - which communicates business perspectives based on pictorial representations, supported by the narrative. Currently, the concept of language is linked to the use of words. We foresee that such a definition of language will have to change to include other structured forms of communication, resorting and relying on graphics, also. We give examples of BNML representations, with regards to two case studies we have performed, based on face-to-face interviews and company visits. At ExpressGlass technology plays an important role, while at Yazaki Saltano a remarkable team effort between Toyota suppliers is made evident, to create innovation.

Classroom is a space where knowledge is acquired in the interaction. However, this interaction is not always symmetric. Teachers and pupils have different rights and obligations, which make them play different roles during the lessons. However, even in very typical hierarchical situations, such as those in institutions, there is always room for improvisation and changes that break the ritual, altering the expected manner by which participants are supposed to interact. These changes cause negotiation of the institutionally imposed roles and reorganize the classroom interactive space. In this article, we discuss data collected from a Portuguese as a Foreign Language (PFL) class in a Luso-Chinese primary school in Macau, southeast China. By using ethnographic microanalysis, moment-by-moment data is interpreted, identifying aspects that reorganize the classroom interactive space. The results indicate that even being the central figure of the interaction, the teacher cannot have total control of her discourse and sometimes loses her role of gatekeeper. Many verbal and nonverbal elements present during the interaction exercise infl uence over the (re)organisation of the interactive space, enabling the students to negotiate the power usually delegated only to the teacher. This kind of participation makes power less teacher-centred once it is not limited to the rules imposed by a traditional teaching system. It also casts doubt on the social determinism that is present in studies carried out in Chinese teaching/learning settings.Keywords: reorganization of interactive space, participation framework, Portuguese as a foreign language, Chinese learners. A sala de aula é um espaço onde o conhecimento é alcançado na interação. Contudo, essa interação nem sempre se dá de forma simétrica. Professores e aprendentes têm diferentes direitos e deveres, o que os fazem desempenhar diferentes papéis durante as aulas. No entanto, mesmo em situações altamente hierárquicas como essas, há sempre um espaço para improvisação e mudanças que alteram a maneira como os participantes interagem. Essas mudanças causam a negociação de papéis institucionalmente impostos e reorganizam o espaço interativo da sala de aula. Neste artigo, discutimos alguns dados coletados de uma aula de Português Língua Estrangeira (PLE) em uma escola luso-chinesa de Macau, sudeste da China. Fazendo uso de uma análise microetnográfica, alguns dados momento-a-momento são interpretados, identificando aspectos que reorganizam o espaço interativo nas aulas. Os resultados indicam que mesmo sendo a figura central da sala de aula, a professora não consegue ter controle total do seu discurso e, por vezes, perde o seu papel de controladora da interação. Vários elementos verbais e não-verbais presentes durante a interação exercem influência na reorganização do espaço interativo, possibilitando aos alunos negociarem o poder usualmente delegado somente à professora. Este tipo de participação torna o poder em sala de aula menos centrado no professor, uma vez que não está limitado às regras impostas pelo sistema tradicional de ensino. Ele também desafia o determinismo social presente em estudos realizados em contextos chineses de ensino-aprendizagem.Palavras-chave: reorganização do espaço interativo, estrutura de participação, português língua estrangeira, aprendentes chineses.
