Lesões no judô: repercussão na prática esportiva / Judo injuries: their repercussions on the practice of the sport

O objetivo deste estudo foi verificar a freqüência de lesões durante a pratica de judô, tempo de afastamento da atividade esportiva e tratamento utilizado em atletas federado praticantes de judô de academias e agremiações no Município do Rio de Janeiro. Método: Participaram do estudo trinta e cinco atletas, sexo masculino, com idade entre 8 e 30 anos e atividade mínima no esporte de 12 meses. Utilizou-se para avaliação um questionário estruturado validado, composto de 18 perguntas abertas e fechadas. Resultados e Discussão: Verificou-se que a maioria das lesões ocorreu durante os treinamentos (82,86%). A maioria permaneceu afastada da pratica esportiva em média entre 15 e 30 dias. Em relação à terapêutica, observou-se que medicamentos antiinflamatórios foram freqüentemente utilizados (71,4%), seguindo-se repouso (62,9%), imobilização (60%) e gelo local (crioterapia) com 51,4%, sendo esta conduta associada à fisioterapia em 40% das lesões. Necessitaram de intervenção cirúrgica 14,3% dos casos. Conclusão: A ocorrência de lesões durante a prática de Judô predomina nos treinamentos, tendo a maioria dos atletas recuperação em tempo inferior a um mês, sendo a principal opção terapêutica o tratamento conservador.

This study sought to verify the frequency of injuries during judo classes, the consequent time away from the practice of the sport, and the treatment used on judo athletes from gyms and clubs located in the city of Rio de Janeiro. Method: Thirty-five male athletes participated in the study, with ages between 8 and 30 years old, with a minimum involvement in the sport of 12 months. A validated and structured questionnaire was used for evaluation composed of 18 questions, both open and closed. Results and discussion: It was verified that the majority of the injuries occurred during the training process (82.86%) and most of the athletes remained away from the practice of the sport on average between 15 and 30 days. In relation to therapy, it was observed that anti-inflammatory medicines were being used more frequently (71.4%), followed by rest (62.9%), immobilization (60%) and ice locally (cryotherapy) (51.4%). This treatment was associated with physiotherapy in 40% of the injuries. Surgical interventions were needed in 14.3% of the cases. Conclusion: the occurrence of injuries during judo practice predominates in the training period, and most athletes can recover in less than one month having a conservative treatment as the main therapeutic choice.

Action of pentoxifylline on experimental cutaneous leishmaniasis due to Leishmania (Leishmania) amazonensis

In the animal model of leishmaniasis caused by Leishmania (Leishmania) amazonensis there is a complex mechanism of the host-parasite interaction. The present study was performed to interfere with the inflammatory reaction to the parasites, through immune modulation. Female C5BL/6 isogenic mice were used, some of which were inoculated on the right ear and others on the right footpad with 3.10(6) stationary phase promastigotes of the MHOM/BR/PH8 strain of L. (L.) amazonensis, and were allocated in three groups: the first received pentoxifylline 8mg/kg every 12 h, since the first day; the second one received the same dose since the 40th day of infection and a control group that did not receive any treatment. All the ears excised were analyzed to determine the variation in weight between both ears and for histopathological analyses. A quantification of the parasites was done using the limiting dilution assay. A significant reduction of the number of parasites, was observed among the animals treated which had an accordingly significant reduction on the weight of the ears. Pentoxifylline reduced the macrophages propensity to vacuolation and induced a more effective destruction of the parasites by these cells. Moreover, the group that began the treatment later did not show the same effectiveness.
