A lei seca cumpriu sua meta em reduzir acidentes relacionados à ingestão excessiva de álcool?

OBJECTIVE: To assess whether the Brazilian Driving Dry Law reached its goal after the three years following its enactment. METHODS: We onnducted a retrospective study of patients with craniofacial fractures who underwent surgery at a university hospital in two periods: before the Law (2005 to 2008) and after the Law (2008 to 2011). RESULTS: 265 patients (220 men and 45 women) were operated on during this period, 149 (56%) before and 116 (44%) after the Law, which indicates a reduction in the number of traumatisms (p=0.04). The age range between 19 and 40 years predominated in both periods. The main causes of traumas were car accidents, physical aggression and falls. Alcohol abuse was identified in 15.4% patients before and 19% patients after the enactment. The jaw and the maxillo-zygomatic complex were the most affected bones. CONCLUSION: The drop in the number of polytraumatized patients operated on at this institution in the three years following the Driving Dry Law was 22%, which is below the expected and desired percentage. These results must be compared to those of different services offering the same attendance type in order to compile data and enlarge statistics. The low index of reduction in the number of traumatisms and the report of alcohol abuse by several patients at the moment of trauma, even after the law, evidence the need of adopting stricter measures to control and punish violators.

Metabolismo oxidativo e cardíaco de equinos submetidos a exercício de baixa intensidade antes e após suplementação com antioxidante

The present study aimed to evaluate cardiac and lipoperoxidation markers in horses subjected to low intensity and long duration (TLD) exercise test, before and after vitamin E supplementation. For this purpose, 10 horses were used, subjecting them to the first TLD with a workload based on individual maximal oxygen uptake (VO2max). Then, horses received vitamin E (dl-alpha-tocopherol) during 59 days at a daily oral dose of 1,000IU, and thereafter they performed a second TLD with the same protocol as the first. Blood samples were collected to determine plasma malondialdehyde (MDA) as an index of lipoperoxidation, serum cardiac troponin I (cTnI) and creatine kinase MB isoenzyme (CK-MB) as cardiac markers. As a result of the exercise, there was no significant increase in MDA or cTnI, but serum CK-MB increased suggesting myocardial stress. The supplementation was able to minimize reactive oxygen species production, as evidenced by lower concentrations of MDA at all times evaluated, but it didn't cause protective effect on the myocardium. It was concluded that the low intensity and long duration exercise promoted light myocardial stress in horses and vitamin E supplementation reduced lipoperoxidation.

Características das lesões desportivas e fatores associados com lesão em iniciantes de ginástica artística do sexo feminino

The artistic gymnastics is a modality that associates arts with biomechanical gestures, and it has been prominent among children and adolescents. Its practice can lead to sports injuries; therefore, it is important to know the factors inherent to trauma for the formulation of preventive models. Thus, the objective of this study was to characterize sports injuries and to verify factors associated with injury in people practicing artistic gymnastics with different levels of competitiveness. Forty-six gymnasts were interviewed with mean age of 10.1±2.0 years for female participants, who were classified in two competitive levels, i.e, initiation and training. We used the morbidity questionnaire adapted to sports characteristics to collect personal, training, and injury data. It was observed that injury risk was 0.3 injuries per athlete and 1.4 injuries per injured athlete, in which the gymnasts of the training category showed a higher frequency of the injury (83.3%; n=10) compared with the ones in the initiation category (10.5%; n=4). For both levels of competitiveness, training moment and light severity were the most reported variables. In the mechanism, contactless was more prevalent in the training category (90%; n=9) and the direct contact was more common at initiation category (75%; n=3). Anthropometric and training variables were considered as factors associated with injury to the gymnasts. It is concluded that gymnasts of the training category have higher injury frequency. Anthropometric and training variables were factors associated with injury. Characteristics of the injuries depend on the competitiveness level of the ­gymnasts.

Órtese de tornozelo: efeito sobre a razão de pico torque muscular eversor excêntrico/inversor concêntrico do tornozelo durante simulação do basquetebol

The ankle sprains represent the most common injuries in sports and basketball. In this sense, the use of ankle bracing and strength capacity analysis of the ankle evertor and invertor muscles, have been suggested as preventive measures and important tools for identifying risk factors associated with ankle sprains. However, questions still persist as to effect of the use ankle bracing on biomechanical variables related to the stability of the ankle. For this reason, this study aims to analyze the effect of the use of ankle bracing on peak torque (PT) of ankle evertor and invertor muscles and on eccentric evertor/concentric invertor torque ratio (EVEECC/INVCON), during the basketball match-play simulation. Ten healthy college basketball players, without mechanics or functional ankle instability performed a laboratory-based protocol representative of work rates observed during basketball match-play, in two different situations, with and without use of ankle bracing. The test was composed of a succession of intermittent physical effort equally distributed in four periods of 10 minutes each, considering the mechanical and physiological demands of a basketball match-play. Prior to the start of the trial (Evaluation 1) and after 2° (Evaluation 2) and 4° (Evaluation 3) periods, the subjects performed five maximal isokinetic concentric and eccentric contractions of ankle invertor and evertor muscles, separated by two minutes rest, at 60 °/s and 120 °/s. After testing for normality of data distribution with the Shapiro-Wilk test, was used the ANOVA repeated measures for two factors and post-hoc Bonferroni test for comparison of variables between assessments. Was adopted p < 0.05. There was no significant difference for PT and EVEECC/INVCON torque ratio between assessments. There was a decrease in PT EVEECC at 60º/s and 120º/s for the ...(Complete abstract click electronic access below)

Efeitos de uma partida sobre o pico de torque funcional e convencional nos músculos isquiotibiais e quadríceps de jogadores de futebol de salão com e sem desequilíbrio muscular

Introdução – Uma das causas mais prováveis de lesões esportivas está relacionada aos desequilíbrios musculares e a fadiga muscular, que é evidenciada no decorrer de um jogo de futebol, principalmente no final do jogo. Esta pode ser avaliada através da comparação da força de contração máxima antes e após o exercício. A fadiga produzida durante o jogo diminui a força muscular concêntrica e excêntrica de flexores e extensores do joelho podendo aumentar a incidência de lesões. Objetivo - Avaliar o efeito de uma partida sobre o pico de torque funcional e convencional nos músculos isquiotibiais e quadríceps de jogadores de futebol de salão com e sem desequilíbrio muscular. Método – Oito jogadores de futebol de salão do gênero masculino, com idade entre 18 e 24 anos, fizeram três visitas ao laboratório: 1ª foram realizadas a antropometria e adaptação aos equipamentos; 2ª teste máximo no dinamômetro isocinético para determinar a razão do pico de torque funcional e convencional nos músculos isquiotibiais e quadríceps; 3ª idem ao 2ª, após a partida de futebol de salão. Análise estatística – através das médias ± DP dos dados obtidos foi utilizado o teste t para amostras dependentes e o Mann Whitney para comparação do pico de torque antes e após a partida de futebol de salão e para comparação da relação flexor/extensor pré e pós- esforço, respectivamente. Em ambos os testes foram adotado um nível de significância de p < 0,05. Resultados - Não foram encontradas diferenças significantes entre os grupos de atletas com desequilíbrio muscular na perna dominante (GD) e grupo equilíbrio (GE) e para os extensores e flexores do GD e GE nas condições Con60. Através do Mann Whitney foram encontradas diferenças...(Resumo completo, clicar acesso eletrônico abaixo)

Análise ergonômica de equipamentos odontológicos

This is study proposes to evaluate the ergonomic aspects of dental equipments. Based on the characteristics proposed by ISO/FDI, on the existing literature and related researches an evaluating system was devised. Thirty nine dental clinics were examined using the 165 pointssystem proposed, distributed in 12 criteria. None of the dental clinics examined showed a bad ergonomics level, 41% were good and 59% reached excellent levels. The point-supported evaluation system proposed is effective in the analysis of the ergonomic conditions of dental equipments, allowing a quantification of their characteristics. Using this system, the dentist can also know the level of ergonomic satisfaction existing in his equipment, and identify the conditions to be improved. It was concluded that the equipment belonging to dental workplaces evaluated had excellent level of compliance, however corrective measures are needed since even the presence of a few non-conforming items is a sufficient condition to cause injury to users, decreased efficiency and comfort and loss quality of service

Diagnóstico molecular da alteração mutagênica nt 230 (del4) no gene MDR1 em cães

P-glycoprotein is an adenosine triphosphate (ATP)-driven drug efflux carrier responsible for transport of xenobiotics and multiple classes of drugs, many usually use in veterinary medicine. Encoded by MDR1 gene, also referred to as ABCB1, located on chromosome 14, is expressed in many tissues with secretory or excretory functions, such as liver, kidney and intestine, where it limits drug absorption from the gut and promotes drug excretion into the bile and urine of their substrates. In 2001, a 4 base pair gene deletion mutation in the canine MDR1 gene was identified as MDR1-1▲, ABCB1-1▲, MDR1 MDR1 nt 230 (del4) and associated with an non-functional Pglycoprotein. The clinical correlation is the (hyper) sensitivity of certain dogs breeds, mostly collies, to a few classes of drugs such as anticancer drugs (doxorubicin, vincristine, vinblastine), immunosuppressants (cyclosporine), antiparasitic drugs (ivermectin, moxidectin), steroids hormones (aldosterone, cortisol, dexamethasone), antimicrobial agents (tetracycline, doxycycline, levofloxacin, ketoconazole, itraconazole), analgesics (morphine, methadone), antidiarrheals (loperamide), antiepileptic agents (phenothiazine), cardiac drugs (digoxin, diltiazem, verapamil, talinolol) and others. Dogs with homozygous MDR1 nt 230 (del4) MDR1 mutations (MDR1 - / -) have a higher predisposition to intoxication with substrates of P-gp than heterozygous (MDR1 + / -) and these are more likely than dogs homozygous nonmutant (MDR1 +/ +). After the identification of nt230 (del4) mutation, several molecular techniques have been developed for identification of mutant animals as a diagnostic method. The importance of molecular diagnosis is, after the identification of mutant animals, establish treatment protocols safe, exclude this animals from reproduction (genetic selection program) and investigating the history of adverse drugs reactions...

A recuperação psicológica de atletas lesionados do futebol

A intervenção psicológica na prática esportiva pode ser realizada através de determinados programas psicológicos de treinamento assim como através de aconselhamento e acompanhamento. As metas principais que podem ser alcançadas através de medidas psicológicas de treinamento são a melhoria planejada e sistemática das capacidades e habilidades psíquicas individuais do rendimento, estabilização e otimização do comportamento na competição e aceleração e otimização de processos de regeneração psicológica. A lesão no esporte tem sido alvo de atenção da psicologia do esporte, em função do número crescente de atletas lesionados, influenciados pela alta exigência do esporte de rendimento, bem como do desejo humano de cada vez querer ir além. Essa demanda máxima em busca do rendimento durante as competições juntamente com o aumento das cargas de trabalho durante os treinamentos ajudam a produzir um progressivo crescimento no número de lesões. Participaram desta pesquisa quinze atletas de futebol, sexo masculino, sendo dez atletas da categoria profissional, um atleta da categoria sub-20 e quatro atletas da categoria sub-17. Eles se encontravam lesionados ou em fase inicial de retorno às atividades, da cidade de Limeira, interior do Estado de São Paulo. A pesquisa, de vertente qualitativa, utilizou-se de um questionário subjetivo (Apêndice) contendo perguntas relacionadas à atual lesão do atleta e também a recuperação fisioterápica e psicológica; para análise dos dados foram feitas leituras e propostas de aglutinação de elementos, por categorização da amostra. A ausência de um psicólogo, em especial do esporte nas equipes, no programa de reabilitação dos atletas entrevistados, fez com que não houvesse a implementação de técnicas de atendimento psicológico, tais como as de visualização...(Resumo completo, clicar acesso eletrônico abaixo)

Trauma cranioencefálico em pequenos animais

Due to the importance of traumatic brain injury (TBI) in small animals, this paper aimed to discuss the pathophysiology of the TBI, the pre-hospital and hospital therapeutic procedures, as well as considerations related to transport and initial care of the patient immediately after trauma. The professional must identify the pre-hospital TBI and to treat the victim as a polytraumatized patient, including immobilization. In hospital therapy the procedures of craniotomy are important, especially to remove blood clots. In addition, the use of glucocorticoids must be avoided because of side effects, but combination therapies such as mannitol with furosemide increase the probability of success

Treinamento aeróbio na prevenção de alterações cardíacas decorrentes da obesidade em ratos (Rattus Norvegicus Albinus, Wistar)

A obesidade é um problema de saúde pública mundial e está fortemente associada à doença cardíaca isquêmica, aterosclerose, hipertensão arterial, entre outros problemas cardiovasculares. Na atualidade, o tratamento sugerido para as doenças cardiovasculares, comumente decorrentes da obesidade, consiste na diminuição da ingestão de gordura aliada à atividade física. Contudo, pouco se sabe quanto aos protocolos de treinamento mais adequados para a prevenção ou tratamento dessas doenças. O presente estudo objetivou analisar os efeitos do exercício físico na intensidade de 80% do limiar anaeróbio (LAn) sobre os aspectos bioquímicos cardíacos de ratos obesos. Para a indução da obesidade, os animais, a partir dos 90 dias de idade, foram mantidos com dieta hiperlipídica/hipercalórica (35% de gordura animal/vegetal) e os animais controles, mantidos com dieta balanceada (AIN-93M). Todos os animais pertencentes ao grupo treinado foram submetidos a testes de lactato mínimo para a identificação do limiar anaeróbio (LAn) durante exercício de natação, treinando desde os 28 dias de idade até aos 90 dias em intensidade equivalente a 80% do LAn 1 h/dia, 5 dias/semana. Depois dos 90 dias uma parte dos animais treinados interrompeu o treinamento ficando em observação até o final do experimento (150 dias de idade). Os demais animais permaneceram sedentários ao longo de todo o experimento. Foram analisados: peso corporal, tolerância à glicose e à insulina (TTGo e TTI), perfil lipídico sérico (colesterol total, triglicerídeos, AGL e HDL), concentrações séricas de glicose e insulina e alíquotas do ventrículo esquerdo foram retiradas para análise das concentrações de triglicerídeos, glicogênio, proteína/DNA e atividade lipogênica. Os animais tratados com dieta hiperlipídica tiveram aumento significativo no peso corporal, intolerância à glicose e resistência à insulina e o treinamento físico neutralizou tais...

Seqüelas em dentes permanentes após trauma nos predecessores decíduos e sua implicação clínica

In regarding to the high prevalence of traumatic dental injuries in primary teeth and the possible disturbances on developing permanent successor germs, an early diagnosis and an adequate establishment of treatment planning are very important to minimize the damage caused by the trauma. Sequelaes can affect the coronal portion (white or yellow-brown discoloration associated or not with enamel hipoplasia, dilacerations of the crown), the root portion (dilaceration, duplication or cessation of root formation) or the whole successor permanent tooth (odontoma sequestration or disturbances of permanent successor eruption). The aim of this study is to make a literature review of the developmental disturbances of permanent teeth followed by traumatic injuries to theirs primary predecessors and to present cases reports to advise the dentists, their patients and parents about the damage that developing permanents teeth can undergo.
