Efeito do lítio sobre a hiperatividade locomotora induzida pela lesão eletrolítica da região do núcleo mediano da rafe em ratos

A lesão do núcleo mediano da rafe (NMR) produz sintomas que sugerem validade de face ao episódio maníaco. Esta pesquisa avaliou o efeito do lítio sobre a hiperatividade locomotora induzida por esta lesão. Vinte e um ratos Wistar machos foram submetidos à lesão eletrolítica da região do NMR (LR) e 17 foram submetidos à lesão fictícia (LF). Após recuperação, a atividade locomotora foi avaliada na caixa de atividade (Med Associates/ENV-515). Parte dos animais destes grupos recebeu tratamentos com lítio (47,5 mg/kg/2x dia i.p.) por 10 dias, enquanto o restante foi tratado com salina no mesmo esquema. A reavaliação ao final dos tratamentos demonstrou que o lítio reduziu significantemente a atividade locomotora em relação à avaliação inicial no grupo LR (ANOVA/Bonferroni p < 0,05), tornando-a equivalente aos baixos níveis dos grupos LF. Estes dados sustentam a hipótese de que as manifestações induzidas pela lesão do NMR podem constituir um modelo animal de mania.

Associação do hidróxido de cálcio e metronidazol no tratamento de dentes de cães com lesão periapical crônica

One of the primary objectives of endodontic treatment of teeth with pulp necrosis is the elimination of microorganisms from the root canal system, as effectively as possible, especially in cases with chronic periapical lesions. AIM: The purpose of this study was to analyze the response of the periapical tissue of dogs' teeth with chronic periapical lesions to endodontic treatment performed with utilization of metronidazole, calcium hydroxide, and an association of both as root canal dressings. METHODOLOGY: Forty root canals were submitted to pulpectomy and the root canals were kept exposed to the oral environment for 6 months. Then, they were submitted to biomechanical preparation and divided into 4 study groups with 10 specimens: group I - no root canal dressing; group II - calcium hydroxide; group III - metronidazole; group IV - calcium hydroxide associated to metronidazole. After 15 days, the root canals were filled with Fill Canal sealer. After 90 days, the animals were killed and the especimens processed for histological analysis. RESULTS: Calcium hydroxide dressing provided a significantly better outcome compared to other experimental groups (α = 0.01). Also, the results of the association of metronidazole and calcium hydroxide were similar to those observed for the metronidazole group. The worst results were obtained by the no root canal dressing group. CONCLUSION: The use of metronidazole alone or associated with Calcium hydroxide, did not improve periapical healing when compared to Calcium hydroxide dressing.

Efeitos da prática da natação adaptada sobre o perfil bioquímico e o estado de condicionamento físico de indivíduos com lesão medular

Introduction: The lack of physical exercises generated by immobilization of the lower limbs leads to changes in body composition that are generally associated with the imbalance of metabolic rate coupled with a sedentary status, which can result in obesity, diabetes mellitus and cardiovascular disease. Therefore, the improvement of physical fitness can contribute to promoting health and quality of life for these patients. As there is a very small number of research in this direction, our purpose was to investigate the effects of an adapted swimming program in protocol interval, for people with spinal cord injury, aiming to verify the improvement of your fitness and, consequently, some biochemical variables important for health. Methodology: The study included 17 subjects with spinal cord injury, sedentary, divided into two groups: 11 participants in the training group (TG) and 6 in control group (CG). TG was applied by a protocol of interval training in swimming for eight consecutive weeks, three times a week. The protocol employed a stroke of breaststroke in work periods of moderate to severe, and stroke in the backstroke, in periods of active recovery. The CG has not participated in any physical activity. Both groups were collecting blood for biochemical analysis, before (evaluation) and after (revaluation) the swimming program. Results and Discussion: The concentrations of triglycerides, total cholesterol and LDL-cholesterol showed no significant changes in assessment for reassessment in both groups. However the TG, the level of HDL-cholesterol were significant differences (p=0,0110), showing an improvement in posttraining, which did not occur in the CG. With respect to the state of fitness, the results revealed a significant difference in relation to time and distance covered in water when compared with the pre-training (p<0,001), showing a great improvement in the ability to shift with the stroke of breaststroke and a significant improvement in cardiorespiratory function. Conclusion: The swimming program interval used, with moderate to severe intensity, can even in a short period of time, promote positive changes in HDLcholesterol in individuals with spinal cord injury studied, and substantially improve your fitness.

Lesão esportiva: Um estudo sobre a síndrome dolorosa femoropatelar

The patellofemoral pain syndrome (PFPS) is defined as a retropatellar or anterior knee pain, without another disease. It affects until 25% of the population, being more common in women and trained persons. As others pathologies, PFPS have been affected the training of elite and amateurs athletes. Thereby, the general purpose of this study was discuss the occurrence of PFPS as a sports injury, there prevention possibilities and the appropriate recovery training after injury. It had been developed a literature review addressing the specific characteristics of the syndrome, its diagnosis, its target population, its development, how it affects the training and which are their possibilities of prevention and treatment. © FTCD/FIP-MOC.

Atuação fisioterapêutica na lesão medular em unidade de terapia intensiva: Atualização de literatura

Objective. Collate and update knowledge in relation to physical therapy in spinal cord injury (SCI) in the intensive care unit (ICU). Method. We performed a literature update in the databases Lilacs, PubMed and Scielo, crossing the descriptors spinal cord injury, cinesiotherapy, physiotherapy, mobilization, rehabilitation, intensive care unit, respiratory therapy and electrotherapy in the period of 2005 to 2010. Results. We found 21 studies, however, only five articles met the inclusion criteria. Kinesiotherapy is essential since the phase of spinal shock, since it favors the maintenance of joint range of motion and flexibility, and to prevent circulatory complications caused/ resulted from prolonged immobilization in bed. Respiratory therapy promotes bronchial hygiene, correction of abnormal respiratory patterns and respiratory diseases. The electrotherapy is a feature still little used by physiotherapists in the intensive care units. Conclusions. The physical therapy in SCI in ICU is focused on motor rehabilitation through kinesiotherapy and intervention through the respiratory bronchial hygiene and training of respiratory muscles. New treatment modalities such as electrotherapy, there have been in intensive environment, there is a need for more studies to confirm benefits and risks of this feature in the spinal cord.
