ABSTRACT
OBJECTIVE: To evaluate the epidemiological and clinical characteristics of knee injuries in Brazilian Jiu-Jitsu (BJJ) practitioners. METHODS: Cross-sectional study, using a mixed questionnaire, based on the Referred Morbidity Index. RESULTS: 198 amateur and professional BJJ fighters, of both sexes, aged between 18 and 60 years, participated in the study. The majority (88%) of the fighters had only one knee injury (p < 0.001). In total, 29.8% proportion of knee injuries (p < 0.001) was identified, which were mainly from the medial collateral ligament (38%), caused by a sprain mechanism (86%) and conservative treatment (65%). CONCLUSION: A high prevalence of knee injuries in JJB fighters was found, compared to other sports that also perform rotational movements and have great body contact, such as mixed martial arts (MMA), judo, soccer, basketball and handball. Some JJB strikes, such as the key and the projection, can cause greater knee joint stress, both in the attacking fighter and in the opponent. The knowledge of the epidemiological characteristics of sports injuries is important in the elaboration of prevention and training protocols more specific to the sport and for the understanding of the complex mechanisms involved with this outcome in sport. Level of Evidence IV, Case Series.
OBJETIVO: Avaliar as características epidemiológicas e clínicas das lesões no joelho de praticantes de jiu-jitsu brasileiro (JJB). MÉTODOS: Estudo de desenho transversal, por meio de questionário do tipo misto, baseado no Índice de Morbidade Referida. RESULTADOS: Participaram 198 lutadores amadores e profissionais de JJB, de ambos os sexos, com idades entre 18 e 60 anos. A grande maioria (88%) dos lutadores apresentou apenas uma lesão no joelho (p < 0,001). Observou-se proporção de 29,8% de lesões no joelho (p < 0,001), que foram principalmente do ligamento colateral medial (38%), causadas por mecanismo de entorse (86%) e de tratamento conservador (65%). CONCLUSÕES: Observou-se alta prevalência de lesões no joelho em lutadores de JJB, comparativamente a outros esportes que também realizam movimentos rotacionais e têm grande contato corporal, como as artes marciais mistas (MMA), o judô, o futebol, o basquetebol e o handebol. Alguns golpes do JJB, como a chave e a projeção, podem causar maior estresse articular no joelho, tanto no lutador que ataca quanto no oponente. O conhecimento das características epidemiológicas das lesões esportivas é importante na elaboração de protocolos de prevenção e treinamento mais específicos à modalidade e também para a compreensão dos mecanismos complexos envolvidos com esse desfecho no esporte. Nível de Evidência IV, Série de Casos.
ABSTRACT
A paralisia facial otogênica decorre devido à interrupção do influxo nervoso no nervo facial em seu trajeto pelo interior do osso temporal, em consequência de diferentes e variados fatores etiológicos. A etiologia infecciosa não é uma das mais frequentes em nosso meio, no entanto deve ser levada em consideração e bem investigada. Existem várias doenças infecciosas que manifestam paralisia facial. Neste trabalho, foi realizada uma revisão da literatura de doenças infecciosas que manifestam paralisia facial.

OBJECTIVE: To evaluate the performance of the turbidimetric method of C-reactive protein (CRP) as a measure of low-grade inflammation in patients admitted with non-ST elevation acute coronary syndromes (ACS). METHODS: Serum samples obtained at hospital arrival from 68 patients (66 11 years, 40 men), admitted with unstable angina or non-ST elevation acute myocardial infarction were used to measure CRP by the methods of nephelometry and turbidimetry. RESULTS: The medians of C-reactive protein by the turbidimetric and nephelometric methods were 0.5 mg/dL and 0.47 mg/dL, respectively. A strong linear association existed between the 2 methods, according to the regression coefficient (b=0.75; 95% C.I.=0.70-0.80) and correlation coefficient (r=0.96; P<0.001). The mean difference between the nephelometric and turbidimetric CRP was 0.02 0.91 mg/dL, and 100% agreement between the methods in the detection of high CRP was observed. CONCLUSION: In patients with non-ST elevation ACS, CRP values obtained by turbidimetry show a strong linear association with the method of nephelometry and perfect agreement in the detection of high CRP.
