Trauma surgery workforce in the state of Rio Grande do Sul, Brazil.

OBJECTIVE: to describe the current scope of certified trauma surgeons trained in the state of Rio Grande do Sul, including demographic data, geographic distribution, remuneration, and perspectives related to this specialty. METHOD: cross-sectional survey based on information collected through an electronic questionnaire sent to potential participants. RESULTS: the response rate was 64% (n=75). There was a predominance of males (72%) with a mean age of 43 years. Most surgeons graduated from the Hospital de Pronto Socorro de Porto Alegre, and work in referral centers for trauma surgery in the capital and metropolitan region. More than 60% did not have any other training in a surgical subspecialty, though only a third stated that trauma surgery is their main source of income. CONCLUSION: trauma centers are poorly distributed and most surgeons work in referral hospitals in the metropolitan region of Porto Alegre. Due to the lack of recognition, limited financial income and shift work patterns, the career in trauma surgery care is unattractive, with only one third of surgeons performing most of their activities in this specialty.

RESUMO Objetivo: descrever o perfil dos cirurgiões do trauma formados no estado do Rio Grande do Sul, incluindo dados demográficos, distribuição geográfica, remuneração, e perspectivas relacionadas à área de atuação. Método: estudo transversal do tipo inquérito, baseado em informações coletadas por meio de questionário enviado via plataforma digital para os profissionais da amostra em questão. Resultados: a taxa de resposta dos questionários foi de 64% (n=75). Houve predomínio do sexo masculino (72%) com idade média de 43 anos. A maior parte dos profissionais foi graduada pelo Hospital de Pronto Socorro de Porto Alegre, e atua em serviços de referência em Cirurgia do Trauma na capital e região metropolitana. Mais de 60% não realizou outra formação em subespecialidade cirúrgica, embora apenas um terço dos profissionais tenha declarado que a Cirurgia do Trauma seja sua principal fonte de renda. Conclusão: os centros de trauma são mal distribuídos e a maioria dos profissionais atua em hospitais de referência da região metropolitana de Porto Alegre. Devido ao baixo reconhecimento, incentivo financeiro limitado e desgaste da modalidade de trabalho em regime de plantão, a carreira com dedicação exclusiva na área de Cirurgia do Trauma é pouco atrativa, com apenas um terço dos profissionais desempenhando a maior parte de suas atividades na área.

Fístula bíleo-brônquica / Bronchobiliary fistula

A fístula bíleo-brônquica é uma condição rara que pode ocorrer em decorrência de cistos hidáticos, intervenções cirúrgicas extensas e procedimentos invasivos para doença hepáticas. O objetivo deste trabalho é relatar o caso de um paciente com diagnóstico de fístula bíleo-brônquica após ferimento por arma de fogo que transfixou o tórax. Ressalta-se a importância de novos relatos a fim de dinamizar o diagnóstico e tratamento desses pacientes e assim diminuírem as morbidades relacionadas.

Broncho-biliary fistula is a rare condition that can occur due to hydatid cysts, extensive surgical interventions, and invasive procedures for liver disease. The aim of this study is to report the case of a patient with a diagnosis of broncho-biliary fistula after a gunshot wound that transfixed the chest. We stress the importance of new reports to streamline the diagnosis and treatment of these patients and thus decrease related morbidities.

Plasma von Willebrand factor levels correlate with clinical outcome of severe traumatic brain injury.

Biochemical markers of cellular stress/injury have been proposed to indicate outcome after head injury. The aim of the present study was to determine whether plasma von Willebrand factor (VWF) levels correlate with primary outcome and with clinical variables in severe traumatic brain injury (TBI). Forty-four male patients, victims of severe TBI, were analyzed. Clinical outcome variables of severe TBI comprised survival and neurological assessment using the Glasgow Outcome Scale (GOS) at intensive care unit (ICU) discharge. Computerized tomography (CT) scans were analyzed according to Marshall CT classification. Three consecutive venous blood samples were taken: first sample (11.4 +/- 5.2 h after trauma, mean +/- SD), and 24 h and 7 days later. The result of mean plasma VWF concentration was significantly higher in the TBI group (273 U/dL) than in the control group (107 U/dL; p < 0.001). Severe TBI was associated with a 50% mortality rate. Nonsurvivors presented significantly higher APACHE II scores than survivors (nonsurvivors mean, 18.8; survivors mean, 12.7; p < 0.001), and also presented higher scores in Marshall CT classification (nonsurvivors mean, 4.6; survivors mean, 2.7; p < 0.05). There was a significant positive correlation between plasma levels at second plasma sampling and scores in Marshall CT classification (p < 0.05). The sensitivity of plasma VWF concentration in predicting mortality according to the cut-off of 234 U/dL was 64%, with a specificity of 68%. Therefore, VWF increases following severe TBI may be a marker of unfavorable outcome.

Increased serum sFas and TNFalpha following isolated severe head injury in males.

OBJECTIVES: Severe traumatic brain injury (TBI) is associated with a 30-70% mortality rate. Nevertheless, controversy has been raised concerning the prognostic value of biomarkers following severe TBI. Therefore, our aim was to determine whether sFas or TNFalpha serum levels correlate with primary outcome following isolated severe TBI. METHODS: Seventeen consecutive male patients, victims of isolated severe TBI (Glasgow Coma Scale score 3-8) and a control group consisting of 6 healthy male volunteers were enrolled in this prospective study. Clinical outcome variables of severe TBI comprised: survival, time for intensive care unit (ICU) discharge, and neurological assessment by Glasgow Outcome Scale at ICU discharge. Venous blood samples were taken at admission in the ICU. Serum sFas and TNFalpha concentrations were measured by ELISA assays. RESULTS: At admission in the ICU (mean time 10.2 h after injury), mean sFas and TNFalpha concentrations were significantly increased in the TBI (0.105 and 24.275 rhog/l, respectively) compared with the control group (0.047 and 15.475 rhog/l, respectively). However, no significant correlation was found between higher serum sFas or TNFalpha concentrations and fatal outcome. CONCLUSIONS: Increased serum sFas and TNFalpha levels following isolated severe TBI did not predict fatal outcome.

Role of serum S100B as a predictive marker of fatal outcome following isolated severe head injury or multitrauma in males.

BACKGROUND: Severe traumatic brain injury (TBI) is associated with a 30%-70% mortality rate. S100B has been proposed as a biomarker for indicating outcome after TBI. Nevertheless, controversy has arisen concerning the predictive value of S100B for severe TBI in the context of multitrauma. Therefore, our aim was to determine whether S100B serum levels correlate with primary outcome following isolated severe TBI or multitrauma in males. METHODS: Twenty-three consecutive male patients (age 18-65 years), victims of severe TBI [Glasgow Coma Scale (GCS) 3-8] (10 isolated TBI and 13 multitrauma with TBI) and a control group consisting of eight healthy volunteers were enrolled in this prospective study. Clinical outcome variables of severe TBI comprised: survival, time to intensive care unit (ICU) discharge, and neurological assessment [Glasgow Outcome Scale (GOS) at ICU discharge]. Venous blood samples were taken at admission in the ICU (study entry), 24 h later, and 7 days later. Serum S100B concentration was measured by an immunoluminometric assay. RESULTS: At study entry (mean time 10.9 h after injury), mean S100B concentrations were significantly increased in the patient with TBI (1.448 microg/L) compared with the control group (0.037 microg/L) and patients with fatal outcome had higher mean S100B (2.10 microg/L) concentrations when compared with survivors (0.85 microg/L). In fact, there was a significant correlation between higher initial S100B concentrations and fatal outcome (Spearman's =0.485, p=0.019). However, there was no correlation between higher S100B concentrations and the presence of multitrauma. The specificity of S100B in predicting mortality according to the cut-off of 0.79 microg/L was 73% at study entry. CONCLUSIONS: Increased serum S100B levels constitute a valid predictor of unfavourable outcome in severe TBI, regardless of the presence of associated multitrauma.

Serum Hsp70 as an early predictor of fatal outcome after severe traumatic brain injury in males.

Severe traumatic brain injury (TBI) is associated with a 35-70% mortality rate. Biochemical markers of cellular stress/injury have been proposed to indicate outcome after head injury. Therefore, our aim was to determine whether Hsp70 could be detected in the serum of patients after severe TBI and whether serum levels of Hsp70 correlate with primary outcome in severe TBI. Twenty consecutive male patients, victims of severe TBI (GCS 3-8), were enrolled in this prospective study. Clinical outcome variables of severe TBI comprised: survival, time for ICU discharge, and neurological assessment using the Glasgow Outcome Scale (GOS) at the ICU discharge. Venous blood samples were taken at admission in the ICU (study entry), 24 h later, and 7 days later. A control group consisting of eight healthy male volunteers was also included. Serum Hsp70 levels were measured by an enzyme-linked immunosorbent assay. Mean serum Hsp70 concentrations were significantly increased in the TBI (97.6, 48.1, and 39.2 ng/mL, at study entry, 24 h later, and 7 days later, respectively) compared with the control group (12.2 ng/mL). Severe TBI was associated with a 50% mortality rate. On study entry (mean time 10.8 h after injury), a higher proportion of patients with fatal outcome had elevated serum Hsp70 (mean 143.5 ng/mL) concentrations when compared with survivors (mean 51.6 ng/mL). There was a significant correlation between higher initial serum Hsp70 concentrations and fatal outcome. The sensitivity of serum Hsp70 predicting mortality according to the cutoff of 62 ng/mL is 70% within 20 h after injury. Increased serum Hsp70 levels may constitute an early predictor of unfavorable outcome in severe TBI in males.
