Referring to judo's sports injuries in São Paulo State Championship

Objective. - In a pioneer way, we investigated the morbidity of sports injuries referred by judo athletes from São Paulo State Championship.Material and methods. - Data collection from 93 senior judokas in State of São Paulo Judo Championship, through Referred Morbidity Inquiry about last year.Results. - One hundred and ten events were registered with a distribution frequency gradient of sprain > contusion > strain > ligament injury > partial and total dislocation. The most injured body areas were: knee (26.3%), shoulder (21.8%), fingers (17.3%), and ankle (10.0%). The most risky situation was when the athlete was training (standing, applying a blow) and it can be explained by the frequent and unprepared exposition of the athletes. Yearly lesion rate was 1.18 injuries per athlete/year.Conclusion. - Sprains constitute the most common judo injury, and athletes are more susceptible when they apply blows; discussion about the direction that the prevention should be applied remains opened.

Occurrence of tooth injuries in patients treated in hospital environment in the region of Aracatuba, Brazil during a 6-year period

Dental trauma has been considered as a public health problem that affects mainly children and youngsters and due to its impact on the patient's quality of life. This study presents the results of a 6-year survey of the occurrence and characteristics of dental trauma in patients admitted to the Service of Surgery and Oral and Maxillofacial Traumatology of the School of Dentistry of Aracatuba (UNESP, Brazil) after emergency care in hospital facilities in the region of Aracatuba, SP, Brazil. For such purpose, the clinical files of patients treated at the Service between 1999 and 2005 were reviewed. Information regarding gender, age, number of traumatized teeth, etiology and diagnosis of the trauma was collected from the files of patients with tooth injuries and recorded in case report forms specifically designed for this purpose. The results showed that from a total of 4112 patients admitted to the Service within the surveyed period, 266 (6.5%) had tooth injuries (172 males - 64.7%; 94 females - 35.3%). The total number of traumatized teeth was 496. Most patients belonged to the 16-20 year-old age group (20.3%) and the most frequent causes of tooth injuries were bicycle accidents (28.6%), motorcycle accidents (19.2%) and falls (18.8%). Injuries to the periodontal tissues were the most frequent type of tooth injuries (408 teeth; 82.26%), occurring in 118 primary and 290 permanent teeth. Among the injuries to the periodontal tissues, avulsion was the most common (32.86%) (29.41% for primary and 34.0% for permanent teeth), followed by extrusive luxation (19.15%) (25.21% for primary and 17.24% for permanent teeth). In conclusion, in the surveyed population, cases of tooth injuries were more frequent in males aged 16-20 years old due to cyclist accidents with predominance of injuries to the periodontal tissues, in particular, avulsions.

Work and injuries in dancers: Survey of a professional dance company in Brazil

This study examined the daily life and most important physical injuries suffered and reported by the dancers of a professional (contemporary) dance company in S (a) over tilde $o Paulo, Brazil. Through an observational, cross,sectional, retrospective procedure using a questionnaire that collected qualitative and quantitative data, we were able to gather information on 30 dancers who collaborated with the survey. We determined that the injuries considered as most important by dancers were those that prevented dance activity during some months. These injuries occurred mainly during rehearsals (which is the activity occuppying, the most time on the schedule). Articular injuries were the most frequent and mainly involved the knee and ankle. They were related to classical technique, in which most of the company's artists started their dance careers. Medical care usually was sought within 1 day, and the prescribed treatment resolved the problem, but the injury cause was not identified in all cases.

Use of rubber tree (Hevea brasiliensis) latex biomembrane in diaphragmatic injuries in rabbits - an experimental study

The aim of this study was to evaluate the surgical use of the natural latex biomembrane in diaphragmatic injuries produced experimentally in rabbits. Fifteen healthy adult male and female New Zealand rabbits were employed. The rabbits were assigned to the experimental groups I, II, III, IV and V and analyzed on the 15th, 30th, 45th, 60th and 90th days post surgery, respectively. The surgical procedure consisted in the access to the diaphragm at the eighth right intercostal space, removal of a circle portion of approximately 1.5 cm in diameter following surgical repair with a latex membrane. Macroscopically, it was observed an excellent healing process during the experimental period. The clinical observations, complemented by the histological analysis, indicate that the latex membrane is useful for repair of traumatic inuries of the diaphragm of rabbits.

Subclinical muscle injuries in dogs infected with Leishmania (Leishmania) infantum chagasi

Although canine visceral leishmaniasis (CVL) has been extensively studied, muscular damage due to Leishmania (Leishmania) infantum chagasi infection remains to be fully established. The aim of this study was to describe the electromyographic and histological changes, as well as search for the presence of amastigote forms of Leishmania spp, CD3+ T-lymphocytes, macrophages and IgG in skeletal muscles of dogs with visceral leishmaniasis (VL). Four muscles (triceps brachial, extensor carpi radialis, biceps femoris and gastrocnemius) from a total of 17 naturally infected and six healthy dogs were used in this study. Electromyographic alterations such as fibrillation potentials, positive sharp waves and complex repetitive discharges were observed in, at least, three muscles from all infected dogs. Myocyte necrosis and degeneration were the most frequent muscular injury seen, followed by inflammatory reaction, fibrosis and variation in muscle fibers size. Immunohistochemistry in muscle samples revealed amastigote forms in 4/17 (23. 53%), IgG in 12/17 (70. 58%), CD3+ T-lymphocytes in 16/17 (94. 12%) and macrophages in 17/17 (100%) dogs. Statistically positive correlation was observed between: inflammatory infiltrate (p=0. 0305) and CD3+ immunoreaction (p=0. 0307) in relation to the number of amastigote forms; inflammatory infiltrate (p=0. 0101) and macrophage immunoreaction (p=0. 0127) in relation to the amount of CD3+; and inflammatory infiltrate (p=0. 0044) and degeneration/necrosis (p<0. 0001) in relation to the presence of macrophages. Our results suggest that different mechanisms contribute to the development of myocytotoxicity, including celular and humoral immune responses and direct muscular injury by the parasite. Nevertheless, the catabolic nature of the disease can probably interact with other factors, but cannot be incriminated as the only responsible for myositis.

Differential effects of variation in athletes training on myocardial morphophysiological adaptation in men: Focus on I-123-MIBG assessed myocardial sympathetic activity

High intensity systematic physical training leads to myocardial morphophysiological adaptations. The goal of this study was to investigate if differences in training were correlated with differences in cardiac sympathetic activity.58 males (19-47 years), were divided into three groups: strength group (SG), (20 bodybuilders), endurance group (EG), (20 endurance athletes), and a control group (CG) comprising 18 healthy non-athletes. Cardiac sympathetic innervation was assessed by planar myocardial I-123-metaiodobenzylguanidine scintigraphy using the early and late heart to mediastinal (H/M) ratio, and washout rate (WR).Left ventricular mass index was significantly higher both in SG (P < .001) and EG (P = .001) compared to CG without a statistical significant difference between SG and EG (P = .417). The relative wall thickness was significantly higher in SG compared to CG (P < .001). Both left ventricular ejection fraction and the peak filling rate showed no significant difference between the groups. Resting heart rate was significantly lower in EG compared to CG (P = .006) and SG (P = .002). The late H/M ratio in CG was significantly higher compared to the late H/M for SG (P = .003) and EG (P = .004). However, WR showed no difference between the groups. There was no significant correlation between the parameters of myocardial sympathetic innervation and parameters of left ventricular function.Strength training resulted in a significant increase in cardiac dimensions. Both strength and endurance training seem to cause a reduction in myocardial sympathetic drive. However, myocardial morphological and functional adaptations to training were not correlated with myocardial sympathetic activity.

Lesões desportivas na natação

O estudo objetivou analisar a ocorrência de lesões em nadadores, associando-as a fatores de risco específicos da modalidade e do atleta. Fizeram parte desse estudo 215 atletas, de ambos os sexos, participantes dos principais campeonatos promovidos pela Federação Aquática Paulista. Os dados foram obtidos por meio de Inquérito de Morbidade Referida, constituído por perguntas relacionadas ao atleta, modalidade e referentes ao tipo, mecanismo e local da lesão. A análise entre variáveis antropométricas e presença de lesão foi realizada pelo teste t de Student ou pelo teste não paramétrico de Mann Whitney. Para relação entre as especificidades e o tipo, mecanismo e local da lesão, utilizou-se o teste de Goodman. Resultados significantes foram obtidos entre os atletas lesionados com mais idade e anos de treinamento. Segundo o mecanismo da lesão, o volume dos treinos é a principal causa de ocorrências de lesões e as tendinopatias são as lesões mais comuns. O ombro é o local mais acometido pelas diferentes especialidades, com exceção dos nadadores de peito que referiram a virilha. Conclui-se a partir dos achados que a exposição dos nadadores a prática esportiva associada ao volume de treinamento estão relacionadas com as frequentes lesões nestes atletas.
