ABSTRACT Open fractures are highly incident injuries closely related to the modern life, in which accidents caused by motor vehicles or other machines impart high energy to bone tissue. Individual morbidity is represented by the functional impairment resultant of infection, nonunion, or vicious healing. In terms of public health, there are huge costs involved with the treatment of these fractures, particularly with their complications. One of the critical issues in managing open fractures is the use of antibiotics (ATB), including decisions about which specific agents to administer, duration of use, and ideal timing of the first prophylactic dose. Although recent guidelines have recommended starting antibiotic prophylaxis as soon as possible, such a recommendation appears to stem from insufficient evidence. In light of this, we conducted a systematic review, including studies that addressed the impact of the time to first antibiotic and the risk of infectious outcomes. Fourteen studies were selected, of which only four found that the early initiation of treatment with antibiotics is able to prevent infection. All studies had important risks of bias. The results indicate that this question remains open, and further prospective and methodologically sound studies are necessary in order to guide practices and health policies related to this matter.

RESUMO As fraturas expostas são lesões altamente incidentes, intimamente relacionadas à vida moderna, na qual os acidentes causados por veículos automotores ou outros aparatos transmitem alta energia ao tecido ósseo. A morbidade individual é representada pelo comprometimento funcional resultante de infecção, não-união ou cicatrização viciosa. Há enormes custos envolvidos no tratamento dessas fraturas em termos de saúde pública, principalmente quanto as complicações. Uma das questões críticas no tratamento de fraturas expostas é o uso de antibióticos, incluindo as decisões sobre quais agentes específicos devem ser administrados, a duração e o momento ideal para a primeira dose profilática. Embora as diretrizes recentes tenham recomendado o início da profilaxia antibiótica o mais rápido possível, essa recomendação parece se basear em evidências insuficientes. Em vista disso, realizamos uma revisão sistemática, incluindo estudos que abordaram o impacto do tempo até o primeiro antibiótico e o risco de resultados infecciosos. Foram selecionados 14 estudos, dos quais apenas quatro concluíram que o início precoce do tratamento com antibióticos é capaz de prevenir infecções. Todos os estudos tinham riscos importantes de viés. Os resultados indicam que essa questão permanece em aberto, sendo necessários mais estudos prospectivos e metodologicamente sólidos para orientar as práticas e políticas de saúde relacionadas a esse assunto.

摘要
OBJECTIVES: The function of a medical expert within the scope of the Brazilian social security system consists of medically evaluating the examinee to draw a conclusive opinion on the person's working ability capacity and to characterize the disability for social security and assistance purposes. Forensic decisions inevitably converge on two opposite outcomes: concession or refusal. Rejection is against the interests of the candidates, who can direct their disappointment and dissatisfaction at the professional, exposing the latter to potentially stressful situations. The present study aimed to determine whether the prevalence of stress and anxiety symptoms is higher among social security medical experts than among medical experts in other public service careers. The study was also intended to propose organizational changes aimed at the preservation and recovery of the mental health of medical experts. METHODS: The evaluation was conducted using a specific, previously validated job-related stress questionnaire and a series of questions about subjective perceptions of work performance, labor stressors and emotional status. RESULTS: We found an overwhelming and alarming prevalence of stress and dissatisfaction related to occupational aspects among social security experts, often culminating in emotional exhaustion, a characteristic feature of burnout syndrome. CONCLUSION: There is a high prevalence of job-related stress among social security doctors in Brazil, warranting implementation of specific measures to ensure the adequate provision of social security services to the population, thus avoiding social injustice and financial damage.

Variations in the insertion of the pectoralis minor muscle have been described. Although much of them were considered to be functionally normal, others may be associated in certain with disconfort related to shoulder movement. Here we described a bilateral, symmetric insertional variation of the pectoralis minor muscle that was found during a routine dissection of upper limbs. In this variation, the tendon crossed the superior surface of the coracoid process to insert on the major tubercle of the humerus head, where it fused with the tendon of the supraspinatus muscle. This variation could be the cause of pain during certain shoulder movements as a result of neurovascular compression, and may lead to mechanical alterations in the muscular dynamics of the shoulder.
