Quand référer aux urgences un patient présentant un trauma de l'appareil locomoteur [When should a patient with musculoskeletal trauma be referred to emergency ward?].

Standardized clinical examination can obviate the need for osteoarticular radiographs for trauma. This paper summarizes a number of decision rules that allow clinical exclusion of significant fracture of the cervical spine, elbow, knee or ankle, making radiographs unnecessary. These criteria were all derived from large cohort studies (Nexus, Ottawa, CCS, etc..., and have been prospectively validated. The rigorous use of these criteria in daily practice improves treatment times and costs with no adverse effect on treatment quality.

Popliteal pseudoaneurysm after unicompartmental knee replacement: a case report.

Popliteal pseudoaneurysm is a rare but important complication of knee arthroplasties. To our knowledge, this complication has not been reported previously in the literature after unicompartmental knee arthroplasty. Apart from intraoperatively caused arterial injuries, obese patients and other previous cardiovascular diseases may be potential factors of risks for pseudoaneurysm in knee surgeries. As it is an uncommon complication and it has inconspicuous symptoms, both diagnosis and treatment can be delayed. This means that a high level of suspicion is necessary to prevent serious complications derived from pseudoaneurysms. LEVEL OF EVIDENCE Level IV.

Infarto cerebral secundario a trombosis de la carótida interna por traumatismo cervical

In this paper, a case of post-traumatic thrombosis in the internal carotid artery after a blow with a ball in the neck of a 33-year-old male is presented. The death came 10 days after the coup as a result of intracranial hypertension and cerebral herniation secondary to ischemic infarction affecting the entire territory of the middle right cerebral artery, both superficial and profound. Macroscopic and microscopic findings that largely explain the mechanism of vascular injury with intimal dissection in the proximity of an atheroma plaque located above the carotid bifurcation are discussed.

Rehabilitation outcomes for orthopaedic trauma individuals as measured by the INTERMED.

PURPOSE: Bio-psychosocial characteristics of patients after orthopaedic traumas may be a strong predictor of poor outcome. The objective of this prospective study was to assess whether the INTERMED, a measure of bio-psychosocial complexity, identifies complex inpatients during rehabilitation including vocational aspects with a poor outcome 1 year after discharge. METHOD: At entry, the INTERMED scores of 118 inpatients were used to assign patients to the high or low complexity group. A questionnaire evaluated 1 year after discharge whether patients: (1) returned to work, (2) still have therapies, (3) take psychoactive drugs, (4) take medication against pain and (5) were satisfied with vocational therapy. Univariate logistic regressions identified which variables predict INTERMED case complexity during hospitalisation as well as predictors (i.e. INTERMED case complexity, French as preferred language, duration of the disability, accident at work, work qualification, severity of the injury, psychiatric co-morbidities, pain) of the five measured outcomes 1 year after discharge. RESULTS: During hospitalisation, the high complexity group was associated with a high prevalence of psychiatric co-morbidities, a higher level of pain and a weaker perception of treatment effects. One year after discharge, the INTERMED was the sole variable to predict all outcomes. CONCLUSION: The INTERMED identifies complex patients during vocational rehabilitation after orthopaedic trauma and is a good predictor of poor outcome 1 year after discharge.

Vascular trauma in the Amazon - the challenge of great distances

ABSTRACTObjective:to evaluate the incidence of unfavorable outcomes in vascular trauma patients and their possible correlation to the distance between the city where the injury was sustained and the hospital where the patient received definitive treatment.Methods:descriptive and retrospective study. Data were collected from medical records of patients submitted to surgical procedures for arterial or venous injuries from February 2011 to February 2013 at the only trauma center providing vascular surgery in a vast area of the Amazon region. Trauma date, patient gender and age, mechanism and anatomic topography of injury, surgical management, need for surgical re-intervention, hospitalization period, postoperative complications, mortality and limb amputation rates were analyzed. The incidence of unfavorable outcomes was assessed according to the distance between the city where the vascular injury was sustained and the trauma center.Results: One hundred seventy-three patients with 255 vascular injuries were analyzed; 95.95% were male (p<0.05), mean age of 28.92 years; 47.4% were caused by firearm projectiles (p<0.05); topographic distribution: 45.66% lower limbs (p<0.05), 37.57% upper limbs, 6.94% abdominal, 5.2% thoracic and 4.62% were cervical vascular injuries; 51.42% of patients required hospitalization for seven days or less (p<0.05); limb amputation was necessary in 15.6% and the overall mortality was 6.36%.Conclusion:distances greater than 200Km were associated to longer hospitalization period; distances greater than 300Km were associated to increased limb amputation probability; severe vascular trauma have an increased death probability when patients need to travel more than 200Km for surgical treatment.

Comparação entre a técnica femoral com dispositivo de hemostasia e a técnica radial em pacientes submetidos à estratégia invasiva precoce

A via de acesso arterial é um importante sítio de complicações após a realização de procedimentos coronários invasivos. Dentre as estratégias para a redução de complicações vasculares, encontra-se estabelecida a eficácia da técnica radial. Os dispositivos de oclusão vascular propiciam maior conforto ao paciente, reduzindo o tempo de hemostasia e repouso no leito. Entretanto, a inconsistência de dados comprovando sua segurança limita sua adoção rotineira como estratégia para redução de complicações vasculares, requerendo evidências de estudos randomizados com metodologia adequada. O objetivo deste estudo foi comparar a incidência de complicações no sítio de punção arterial entre a técnica radial e a técnica femoral com utilização de Angio-Seal em pacientes com síndrome coronariana aguda sem supradesnível do segmento ST submetidos à estratégia invasiva precoce. Trata-se de um ensaio clínico unicêntrico, de não inferioridade, no qual duzentos e quarenta pacientes foram randomizados para a técnica radial ou técnica femoral com utilização de Angio-Seal. O objetivo primário foi a ocorrência de complicações no sítio de punção arterial até 30 dias após o procedimento, incluindo sangramento grave, hematoma >= 5 cm, hematoma retroperitoneal, síndrome compartimental, pseudoaneurisma, fístula arteriovenosa, infecção, isquemia de membro, oclusão arterial, lesão de nervo adjacente ou necessidade de reparo vascular cirúrgico. Em relação às características demográficas e clínicas, houve diferença apenas quanto ao gênero, com presença maior de pacientes do sexo feminino no grupo radial (33,3% versus 20,0%, p=0,020). Não se observaram diferenças entre os grupos quanto ao diagnóstico de admissão, alterações isquêmicas presentes no eletrocardiograma, elevação de marcadores de necrose miocárdica ou escores de risco, bem como quanto à farmacoterapia antitrombótica adjunta e características da intervenção coronária percutânea. A hemostasia foi obtida na totalidade dos procedimentos do grupo radial com a utilização da pulseira compressora seletiva TR Band e em 95% dos procedimentos realizados pela técnica femoral com o Angio-Seal (p=0,029). Exceto pela maior incidência de oclusão arterial no grupo radial comparado ao femoral, não houve diferenças entre os demais desfechos analisados. Segundo o teste de não inferioridade para complicações na via de acesso arterial aos 30 dias, verificou-se que a utilização do Angio-Seal não produziu resultados inferiores ao acesso radial, considerando-se a margem de 15% (12,5% versus 13,3%, diferença -0,83%, IC 95% -9,31 - 7,65, p para não inferioridade <0,001). Os resultados principais deste estudo demonstram que, em uma população de pacientes com diagnóstico de síndrome coronariana aguda sem supradesnível do segmento ST, submetida à estratificação de risco invasiva, a utilização do dispositivo de oclusão vascular Angio-Seal confere ao procedimento efetivado pelo acesso femoral inferioridade na incidência de complicações no sítio de punção arterial aos 30 dias quando comparado ao acesso radial.
