Características cinemáticas, cinéticas e eletromiográficas do andar de adultos jovens com e sem suporte parcial de peso corporal

OBJETIVO: O objetivo deste estudo foi analisar as características cinemáticas, cinéticas e eletromiográficas do andar de adultos jovens em piso fixo sem colete e com suporte parcial de peso (SPP) de 0, 10, 20 e 30% do peso corporal. MÉTODO: Oito jovens com idade média de 22,2 anos foram filmados andando sobre uma passarela que continha uma plataforma de força na região central para registro das componentes da força de reação do solo. Marcadores refletivos foram posicionados nos principais pontos anatômicos dos membros inferiores para registro dos dados cinemáticos, e eletrodos de superfície foram afixados nos músculos tibial anterior e gastrocnêmio medial para registro da atividade elétrica muscular. RESULTADOS: Diferenças significantes entre as cinco condições experimentais foram constatadas nas variáveis espaço-temporal, nos ângulos máximos e mínimos da coxa, joelho e tornozelo e nas amplitudes das componentes horizontal ântero-posterior e vertical da força de reação do solo. de forma geral, as maiores mudanças ocorreram na condição de SPP de 30% do peso corporal. CONCLUSÃO: É importante considerar as compensações que ocorrem no padrão do andar com SPP no planejamento das intervenções terapêuticas. Ainda, para melhor definir a utilização dos sistemas de suspensão de peso na reabilitação, estudos futuros precisam ser realizados para verificar o comportamento do andar em populações com alteração de movimento em piso fixo.

Central Giant Cell Granuloma in Pediatric Maxilla: Surgical Management

Central giant cell granuloma (CGCG) is an intraosseous lesion consisting of fibrous cellular tissue that contains multiple foci of hemorrhage, multinucleated giant cells, and occasional trabeculae of woven bone. An 8-year-old boy presented himself complaining of a painless swelling in the left maxilla that had started 1 year. Computed tomography (CT) scan confirmed a poorly defined multilocular radiolucent lesion in the left maxilla crossing the midline. The patient underwent enucleation through an intraoral approach of the lesion. The biopsy revealed multinucleated giant cells in a fibrous stroma. A CT was taken approximately 1 year postoperatively. There was no clinical or radiographic evidence of recurrence. Therefore, surgical treatment of CGCG can be performed, trying to preserve the surrounding anatomic structures, which can be maintained in case the lesion does not show an aggressive clinical behavior, avoiding large surgical defects which are undesirable in children.

Isolated Bilateral Blowout Fracture With Extensive Pneumatization of the Maxillary Sinuses

The blowout fracture injuries are often associated with fractures of the zygomatic complex and other facial structures but can also occur in an isolated fashion. Isolated bilateral blowout fractures are uncommon and constitute a challenge with regard to both assessment and reconstruction. This article describes an uncommon case of isolated bilateral blowout fracture in a patient with extensive pneumatization of the maxillary sinuses.

Alterações antropométricas de lesados medulares após treinamento intervalado em natação

The goal of this study was to assess the alterations in some anthropometric measures of sedentary subjects with spinal cord injury after a swimming interval training program with the use of a lifejacket. The study included 17 male spinal cord injured subjects, divided into two groups: 11 subjects in the training group (TG) and 6 in the control group (CG).The protocol employed a stroke of breaststroke, in work periods of moderate to severe, and stroke in the back stroke in periods of active recovery. An anthropometric evaluation was applied before the application of the training protocol and another (reevaluation) after 8 weeks. In the TG, the results obtained after the swimming program showed a significant change (p < 0.05) in the supra-iliac (SICF) and in the triciptal cutaneous folds (TCF), arm and waist circumference measures, from the first evaluation to the reevaluation. In the CG there were no significant changes observed in any of the variables studied. When comparing the two groups after the swimming training program, the average of the variable SICFT in the TG was significantly lower than the average for the CG. Generally speaking, the out comings showed the swimming protocol efficiency in promoting desirable anthropometric changes in spinal cord injured subjects while a reduction of fatty tissue in the arms and abdominal region and an increase of muscular tissue in the upper limbs of those subjects also occurred.
