Ocorrência de úlcera de pressão em indivíduos com lesão traumática de medula espinhal / Pressure ulcers in individuals with spinal cord injury / Ocurrencia de úlcera de presión en indivíduos con lesión traumática de la médula espinal

Este estudo caracterizou o perfil de 54 pacientes atendidos em um hospital com Lesão Traumática de Medula Espinhal, em relação a ocorrência de úlcera de pressão e fatores associados. Trata-se de uma população jovem e masculina. O trauma foi mais comum na região da coluna torácica, causado por acidente de trânsito. A úlcera de pressão foi identificada em 63% dos pacientes, sendo mais freqüente na região sacral e dos calcâneos e nas internações maiores de 16 dias. Observa-se a necessidade de implantar medidas institucionais para a prevenção da úlcera envolvendo uma equipe multidisciplinar, o paciente e seu cuidador/ familiar

This study describes the profile of 54 patients in a hospital, with spinal cord injury, for pressure ulcers and associated factors. It is a young male population. The most common trauma was in the chest spine and was more frequent in the sacral and heel regions and when the length of stay was longer than sixteen days. There is a need for institutional measures to prevent ulcers, which should involve a multidisciplinary team, the patient and his caregiver/family members

Morphometric study of the plasticity of nerve fibers of spared spinal dorsal root and its terminals in rats / 第三军医大学学报

The number of nerve fibers in the spared dorsal root of the L4 spinal nerve and the number of nerve terminals in the Lamina Ⅲ of the segment of the spinal cord between L2 and S1 were determined with electron microscopic morphometry,and the distribution and density of nerve fibers in the spinal cord were observed with silver staining.It was found that the distribution and density of nerve fibers in the spinal cord showed no difference between the operated and the control sides under optical microscopy;morphometric analysis revealed a significant increase of the number of unmyelinated fibers and a tendency to increase of their diameter;and the number of both simple and complex terminals in the Lamina Ⅲ of the spinal cord could return to the normal level on the 35th day after operation with a significant increase of their diameter.The importance of these changes was preliminarily discussed.
