Abstract: Third molar extraction surgery is one of the most frequently performed procedures in the areas of buccal-maxillofacial traumatology and surgery. The post-surgery evolution was evaluated based on the clinical evidence obtained so far. The objective of this study was to analyze the post-surgery clinical evolution of the masseter muscle by means of surface electromyography, to evaluate muscle activity. Four analyses were performed: one pre-surgery, to register the normal activity, and three in post-surgery: on the 7th, 14th and 21st postoperative days, in a sample of 30 patients. On the 21st day, there was near normal recovery of the electrical signal of the masseter in women, but in men this activity did not reach normal levels. Surface electromyography is a safe and reliable tool for post-surgery evolution control of masseter function. La cirugía de extracción del tercer molar es uno de los procedimientos realizados con mayor frecuencia en las áreas de traumatología y cirugía buco-maxilofacial. La evolución post-quirúrgica fue evaluada sobre la base de la evidencia clínica obtenida hasta el momento. El objetivo de este estudio fue analizar la evolución clínica post-operatoria del músculo masetero por medio de electromiografía de superficie, para evaluar la actividad muscular. Fueron realizados cuatro análisis: uno previo a la cirugía, para registrar la actividad normal, y tres en la post-quirúrgica: en el día del 7, 14 y 21 postoperatorio, en una muestra de 30 pacientes. El día 21, hubo recuperación cercana a la normal de la se al eléctrica del músculo masetero en las mujeres, pero en los hombres esta actividad no alcanzó los niveles normales. La electromiografía de superficie es una herramienta segura y fiable para el control de la evolución post-quirúrgica de la función del músculo masetero.

Abstract: INTRODUCTION: Traumatic spinal cord injury is one of the most disabling conditions occurring in man and thus stimulates a strong interest in its histopathological, biochemical, and functional changes, primarily as we search for preventive and therapeutic methods. PURPOSE: To develop an experimental model for transplantation of cells from the fetal rat central nervous system to the site of an injured spinal cord of an adult rat in which the transplanted cells survive and become integrated. This experimental model will facilitate investigations of factors that promote regeneration and functional recovery after spinal cord trauma. MATERIAL AND METHODS: Fifteen adult Wistar rats underwent laminectomy, and an spinal cord lesion was made with microdissection. Fetal spinal cord tissue was then transplanted to the site of the injury. The rats were monitored over a 48-hour period, and then their vertebral column was completely removed for histological analysis. RESULTS: In 60% of transplanted rats, the fetal tissue at the injured site remained viable in the site of the lesion.

Abstract: objectives: the objectives of this study were to develop a pointing device controlled by head movement that had the same functions as a conventional mouse and to evaluate the performance of the proposed device when operated by quadriplegic users. methods: ten individuals with cervical spinal cord injury participated in functional evaluations of the developed pointing device. the device consisted of a video camera, computer software, and a target attached to the front part of a cap, which was placed on the user's head. the software captured images of the target coming from the video camera and processed them with the aim of determining the displacement from the center of the target and correlating this with the movement of the computer cursor. evaluation of the interaction between each user and the proposed device was carried out using 24 multidirectional tests with two degrees of difficulty. results: according to the parameters of mean throughput and movement time, no statistically significant differences were observed between the repetitions of the tests for either of the studied levels of difficulty. conclusions: the developed pointing device adequately emulates the movement functions of the computer cursor. it is easy to use and can be learned quickly when operated by quadriplegic individuals.

Abstract: Post laminectomy fibrosis in spine surgery has been responsible for a high rate of failure in a short or long term. Many of this patients develop chronic or recurrent pain after surgery of discal herniation, canal stenosis etc. Although there some doubts about the etiology of this problem, it was known that fibrosis interfere with the normal mobility of roots and spinal cord. This factor is considered as the most important aspect in the genesis of the surgical failures. To avoid postoperative fibrosis, a lot of materials of interposition between posterior spine muscles and dura mater were studied, without good response. This paper studied comparatively post laminectomy fibrosis in Wistar rats with the addition of the following materials to avoid it: control group (without interposition) and expanded inert polytetrafluoroethylene membrane (Preclude Spinal Membrane ). It was observed that accurate surgical technique apparently is an important factor to prevent the formation of abundant scar tissue and that the expanded inert polytetrafluoroethylene membrane is an inert material.

Abstract: in the last decades, there has been an increasing use of instruments with pedicular screws for treating thoracic-lumbar spine fractures. this kind of fixation has the advantage of stabilizing the denis? three columns, as opposite to other instruments previously used, but it presents as a possible and feared complication the potential of vertebral channel penetration, pedicular fractures, involvement of nervous roots and vascular injuries. our study aims to evaluate if computed tomography is a good analysis method for pedicular screws positioning and the potential complications of surgically passing them. nineteen patients have been studied, totaling 134 screws, during the period ranging from november 2002 to february 2005, regarding x-ray, tomography and pre- and postoperative neurological function analyses. as a result, there were two cases of injury on pedicle?s lateral wall at the tomography image, with no clinical repercussion to patients. regarding neurological deficit, no patient showed a worse condition. six patients presented with an improved neurological status. we concluded that computed tomography is an excellent imaging test for evaluating pedicular screws, and this kind of fixation was safe and showed low morbidity rates, allowing an early mobilization of the patient.
