Treatment and complications of orbito-zygomatic fractures

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

Radiographic and clinical evaluation of zygomatico-maxillary complex fractures treated by 2.0 miniplates system

The zygomaticomaxillary complex (ZMC) is the second highly incidental of facial fractures. According to the anatomical complexity, there are many reports in the literature about this trauma, mainly related to treatment for these fractures. With the purpose of evaluating clinically and radiographically the stability of unilateral zygomatic fractures treated by surgical reduction and fixed in two points by stable internal fixation, this research was proposed. Twenty patients with zygomatic fractures were evaluated and compared with twenty nonfractured patients. The results showed that there were no statistically significant differences among the obtained data, perimeter and area, of the treated and contra-lateral sides of the experimental group. When compared to the control group the differences were not statistically significant. We also performed a comparison of the distance between the nasal bone and zygomatic prominence in all groups the results were also satisfactory.

O lugar da psicanálise e a universidade

As a usual practice in society, psychotherapy is considered a normal procedure, but how does it take place in an investigation method of subjectivity in the university? The theory of speech of Lacan helps us to locate a place to psychoanalysis in the university as a language practice in the role of teaching, research and extension (community work). In this sense, the university submits the ideas of conscience to science and material rationality, excluding the individual and the unconscious. The theory of speech helps us to see the difference between the speech the students use and the speech the annalist uses in his practice. The psychoanalysis has its own knowledge based on the unconscious, due to the clinic work precedes as well as the work in university extension (community work). The work of the annalist has his particular world to treat his mane object — the unconscious.

Programas de intercâmbio/cooperação internacional em lazer no contexto dos grupos de pesquisa nacionais da área

Este estudo objetiva mapear e descrever programas de intercâmbio/cooperação internacional em lazer, desenvolvidos por grupos de pesquisa (GP) brasileiros. Realizou-se investigação descritiva exploratória, com abordagem quantiqualitativa, em duas fases: 1) mapeamento dos GP em lazer cadastrados no CNPq; 2) contato com os representantes destes GP. Participaram 54 representantes de 211 GP. Nove apontaram o desenvolvimento destes programas por meio de relações com diferentes países. Os trabalhos em colaboração e os intercâmbios são as ações mais frequentes dos programas. Apesar de haver disparidade regional na distribuição dos GP, curta duração e execução de ações isoladamente, acredita-se que estes programas tenham propostas promissoras para o lazer, suscitando novas investigações.

¿Presenta la anémona Anemonia sulcata (Pennant, 1777) comportamiento de homing?

[ES] Se estudia la capacidad de retorno al lugar de origen en Anemonia sulcata en su medio natural. Treinta y dos individuos fueron marcados en charcas intermareales, de los cuales 20 fueron desplazados, 5 y 10cm, de sus posiciones originales. Posteriormente se observó el movimiento de todos ellos en las siguientes 48h. De todas las anémonas trasladadas, un único individuo volvió exactamente a su lugar de origen recorriendo, en las primeras 24h, los 10cm que había sido desplazado. Con los resultados obtenidos en este trabajo, Anemonia sulcata no parece presentar fidelidad por un lugar en concreto dentro de su charca. Al ser trasladado desde su lugar inicial, simplemente busca un nuevo punto de fijación y lo hace tomando una dirección aleatoria. A falta de estudios más exhaustivos, se puede afirmar que esta especie no presenta comportamiento de homing.
