Tecnoimagens do cuidado-aprendizagem: inventário do trabalho vivo em ato como proposta de tecnologia educacional para o Sistema Único de Saúde / Care-learning technoimages: inventory of live work in action as a proposal of educational technology for the Unified Health System

Este estudo, de abordagem científica e artística, foi desenvolvido com ficção metodológica a fim de produzir tecnologia educacional em saúde. Apresenta um percurso criativo, investigativo e experimental de construção de trajetória profissional na assistência e na docência. Teve como objetivo inventariar readymades criados no trabalho vivo em ato para engendrar tecnologias educacionais no Sistema Único de Saúde (SUS). Os caminhos desta produção tiveram como estrutura fundamental o papel do componente estético artístico na prática profissional em ciência e a formação de saberes e fazeres constituintes do profissional de saúde a partir dos modos como foram gradativamente incluídos nos rituais de saúde e de docência. Este inventário é produto de encontros com objetos do trabalho em saúde, usuários e trabalhadores da saúde por diversos lugares. Juntos, eles formam os principais territórios das reflexões somados a conexões com leituras e anotações de oficinas ministradas e assistidas; de vídeos e espetáculos vistos; de poemas lidos e escritos, de pacientes atendidos; de conversas com outros profissionais da educação e da saúde em espaços não-formais; e de outras atividades, muitas diretamente relacionadas a tecnologias em saúde e outras nem tanto. Os resultados foram apresentados na forma de uma instalação denominada Inventário Tecnológico. Readymades ou tecnoimagens do cuidado aprendizagem foram a tecnologia produzida na intenção de promover vivência estética inspirada no universo dos procedimentos e dos objetos hospitalares. Um convite para desemoldurar as práticas do cuidado cotidiano em saúde e a convocação do corpo sensível para o processo do encontro com o outro. (AU)

Geometrical characterization of the cavitation bubble clouds produced by a clinical shock wave device

This study was to optically visualize the cavitation bubbles produced by a clinical shock wave and to look into their geometric features of the resulting cavitation bubbles in relation to the driving shock wave field. A clinical shock wave therapeutic system was taken for shock wave production. The shock wave induced cavitation bubbles were captured by a professional camera under the illumination of a micro-pulse LED light. The light exposure was set to last for the whole life time of bubbles from formation to subsequent collapses. It was shown that the cavitation bubbles appeared mostly in the vicinity of the focus. The bubbles became more and larger as approaching to the focus. The cavitation bubbles formed jet streams which became enlarged (stronger) as the shock wave device output setting increased. The bubble cloud boundary was reasonably fitted to an elongated ellipsoid characteristically similar to the acoustic focal area. The bubble clouds were enlarged as the output setting increased. The geometric features of the cavitation bubbles characteristically similar to those of the focusing acoustic field have potential to provide the therapeutic focal information without time consuming hydrophone measurements of the shock wave field causing damages of the expensive sensor. The present study is limited to the static afterimages of the cavitation bubbles and investigation including the bubble dynamics is suggested to deliver the more realistic therapeutic area of the shock wave therapy.

Palinopsia Preceding a Seizure in a Patient with Arteriovenous Malformation in the Occipito-Temporal Lobe

Palinopsia means a visual image persisting for minutes to hours or reappearing episodically after the exciting stimulus has been removed. The anatomic correlation of palinopsia is not clear, whereas occipito-parietal and occipito-temporal lesions have been implicated. We describe a patient presenting palinopsia prior to motor seizures which was related to left posterior temporal lesion. A 36-year-old man had a generalized tonic clonic seizure after palinoptic positive visual afterimages. Brain MRI and Transfemoral cerebral angiography (TFCA) revealed an arteriovenous malformation of 1x1.5x2 cm3. We used oxcarbazepine for preventing recurrent seizures and planned gamma knife radiosurgery. Palinopsia is a very rare clinical manifestation as an aura of seizures. Palinopsia preceding clinical seizure as a localizing value, so that neuroimaging is mandatory in this clinical situation. This is the first reported case of palinopsia in Korea.
