Cancer is a significant health problem in the adolescent and young adult population. Confusion exists within the field of pediatric oncology with respect to the definition of childhood cancer, since most population-based incidence studies define childhood cancer on the basis of age alone. We recommend that the scope of pediatric oncology include the study(More)
OBJECTIVE The purpose of this study was to determine the MR findings in patients with giant cell tumors of the tendon sheath. MATERIALS AND METHODS MR imaging findings in nine surgically proved cases of giant cell tumors of the tendon sheath were evaluated on both T1- and T2-weighted images. Of nine lesions, three involved the foot, two involved the(More)
Traditional approaches of assessment in the medical domain are insufficient for evaluating trainees' technical skills. Currently, many European medical training bodies are attempting to introduce competence-based training programmes for technical skills as well as other domains (e.g., communication, professional behaviour, clinical cognition). These efforts(More)
The authors present an approach for implementing a system for the assessment of medical competences using a haptic simulation device. Based on Competence based Knowledge Space Theory (CbKST), information on the learners' competences is gathered from different sources (test questions, data from the simulator, and supervising experts' assessments). The(More)
This paper describes the development of a technology architecture that not only supports the technical performance assessment of a medical simulator but also facilitates a validated competence based assessment system in one selected anaesthetic procedure i.e. spinal anaesthesia. Based on extensive mapping of the competencies required for the performance of(More)
BACKGROUND AND OBJECTIVES Having identified key determinants of teaching and learning spinal anesthesia, it was necessary to characterize and render the haptic sensations (feeling of touch) associated with needle insertion in the lower back. The approach used is to match recreated sensations (eg, "pop" through skin or dura mater) with experts' perceptions(More)
BACKGROUND AND OBJECTIVES Training in medical procedural skills is currently undergoing important change. We set out to identify those factors, perceived by trainers and trainees, to be important determinants of learning ultrasound-guided axillary brachial plexus blockade (USgABPB). METHODS We performed a structured, prospective, qualitative analysis of(More)
This paper discusses the shortcomings of the cognitive science approach to understanding human cognition particularly in its relationship to human computer interaction. Its failure to distinguish between the psychic and the information processes in human and machine has led to a view of the computer as a 'replacement' for the human in intellectual spheres(More)
BACKGROUND Detailed description of the tasks anesthetists undertake during the performance of a complex procedure, such as ultrasound-guided peripheral nerve blockade, allows elements that are vulnerable to human error to be identified. We have applied 3 task analysis tools to one such procedure, namely, ultrasound-guided axillary brachial plexus blockade,(More)
