Epidemiological study of pediatric trauma in a reference hospital in Curitiba.

OBJECTIVE: to analyze the prevalence of types of trauma, resulting injuries and managements in children and adolescents between 0 and 17 years old, treated in an Emergency Room in 2019. METHODS: a retrospective cross-sectional descriptive study carried out by collecting data from medical records from January to December of 2019, encompassing pediatric trauma victims, divided according to age groups: infants (0-1 year), preschool children (2-4 years), school children (5-10 years) and adolescents (11-17 years). RESULTS: 3,741 patients records were included in the study. The search for assistance occurred spontaneously in about 70% of the cases and males were the most affected at all ages. In infants and preschoolers, the main mechanism of trauma was fall from heights, corresponding to 57.2% and 34.1%, respectively, whereas in school children and adolescents, the main mechanism was ground-level falls (38%) and sports trauma (22,3%), in this order. The main injuries presented, in general, were traumatic brain injury (28,2%), upper limb contusion (23,2%) and upper limb fractures (16,3%). CONCLUSIONS: the profile of the victims analyzed indicates the male sex as the most affected, with the trauma mechanism being the differential according to age. The most frequent mechanism is falls, more prevalent in infants and preschoolers, and the most common injury is extremity contusion, with the upper limbs being the most affected. In general, the cases were considered of low complexity, with a hospitalization rate of 6%.

RESUMO Objetivo: analisar a prevalência dos tipos de trauma, lesões decorrentes e condutas tomadas em crianças e adolescentes entre 0 e 17 anos, atendidos em um Pronto-Socorro no ano de 2019. Métodos: estudo transversal retrospectivo descritivo realizado através do levantamento de dados dos prontuários médicos no período de janeiro a dezembro de 2019, englobando pacientes pediátricos vítimas de trauma, divididos conforme a faixa etária: lactentes (0-1 ano), pré-escolares (2-4 anos), escolares (5-10 anos) e adolescentes (11-17 anos). Resultados: foram incluídos no estudo 3741 prontuários de pacientes. A procura de assistência médica ocorreu de maneira espontânea em cerca de 70% dos casos, sendo o sexo masculino o mais acometido significativamente em todas as idades. Em lactentes e pré-escolares, o principal mecanismo de trauma foi a queda de outro nível, correspondendo a 57,2% e a 34,1% das ocorrências, respectivamente; já nos escolares e adolescentes o principal mecanismo foi a queda de mesmo nível (38%) e o trauma esportivo (22,3%), nessa ordem. As principais lesões apresentadas, de maneira geral, foram o traumatismo cranioencefálico (28,2%), contusão de membros superiores (23,2%) e fratura de membros superiores (16,3%). Conclusões: o perfil das vítimas analisadas aponta o sexo masculino como o mais acometido, sendo o mecanismo de trauma o diferencial conforme a idade. Os mecanismos mais frequentes são as quedas, mais prevalentes em lactentes e pré-escolares, e a lesão mais comum é a contusão de extremidades, sendo os membros superiores os mais acometidos. Em geral, os casos foram considerados de baixa complexidade, com uma taxa de internação de 6%.

Non-cirrhotic portal vein thrombosis - therapeutic challenge.

Portal vein thrombosis (PVT) is a disease in which thrombosis occurs from the intrahepatic branches of the portal vein, and may extend to the splenic vein and/or superior mesenteric vein. It is most often associated with liver cirrhosis. PVT not associated with cirrhosis is rare. The aim of this article is to report two cases of PVT in which it was not associated with cirrhosis. Both were treated with anticoagulation and clinical progress afterwards was good.

Epidemiological analysis of cardiac trauma victims at a referral trauma hospital: a 5 year case series.

OBJECTIVE: to describe, analyze, and trace the epidemiological profile for cardiac trauma victims on a referral trauma hospital of a major urban center. METHODS: a case series study to review, describe, compile and analyze medical records of all patients sustaining traumatic cardiac injuries, from January 2015 to January 2020 admitted to the referral trauma hospital of Curitiba, Brazil. Patients sustaining traumatic heart injuries were identified using the hospitals database. Patients who died prior to reaching hospital care were excluded. RESULTS: all 22 cases were urban victims, mostly penetrating injuries (12 stab wounds, 9 gunshot wounds); 82% were male; mean age, 37.1 years. 17 cases (77%) occurred during night hours, 15 between Friday and Sunday, and 15 were admitted hemodynamically stable. Only 27% were diagnosed with FAST, the remainder requiring other imaging exams. About incisions, 14 had thoracotomies, 6 median sternotomies and in 2 cases both. Of injuries, 8 affected the right ventricle, 3 right atrium, 9 left ventricle, 1 right coronary sulcus and 1 anterior wall. All had cardiorrhaphy repair. 3 patients died, 17 were discharged and 2 were transferred. 17 received postoperative echocardiograms, revealing ejection fractions ranging 55.1% to 75%. Patients spent a mean of 9.6 days on ICU and a mean of 15.2 days of total hospital stay. The mortality rate was 14%. CONCLUSIONS: cardiac traumas predominantly occurred in adult males, due to violent causes, during night hours on weekends. The overall mortality rate found (14%), as well as total hospital stay, accords with the literature.

Axillary-iliac bypass to protect a transplanted kidney during abdominal aortic aneurysm repair: case report.

Abdominal aortic aneurysms (AAA) are the most common type, even when compared to those involving other segments of the aorta. The prevalence and natural history of arterial aneurysms in abdominal organ transplant recipients remain uncertain. We report a case of abdominal aortic aneurysm in a kidney transplant patient with contrast allergy. Conventional abdominal aortic aneurysm repair was performed, constructing a bi-iliac aortic bypass. A temporary bypass was constructed from the right axillary artery to the right common iliac artery to maintain the renal graft. The patient was transferred to the intensive care unit, where he remained hemodynamically stable, and he was discharged on the 2nd postoperative day. Conventional open surgery with temporary extra-anatomic bypass is an alternative option for treatment of AAA in patients with transplanted kidneys.

Derivação axilo-ilíaco para proteção de rim transplantado durante a correção de aneurisma de aorta abdominal: relato de caso / Axillary-iliac bypass to protect a transplanted kidney during abdominal aortic aneurysm repair: case report

Resumo Os aneurismas de aorta abdominal (AAA) são os mais frequentes, mesmo quando comparados a outros segmentos da aorta. A prevalência e a história natural de aneurismas arteriais em receptores de transplante de órgão abdominal permanecem incertas. Relatamos a abordagem de um caso de aneurisma de aorta abdominal em um paciente transplantado renal e com alergia ao contraste. Foi realizado o tratamento convencional do aneurisma de aorta abdominal com um by-pass aorto bi-ilíaco. Para manutenção do enxerto renal, foi confeccionado um by-pass temporário da artéria axilar direita até a artéria ilíaca comum direita. O paciente foi encaminhado para a unidade de terapia intensiva, onde permaneceu estável hemodinamicamente e recebeu alta no 2º pós-operatório. A cirurgia convencional aberta com derivação extra-anatômica temporária é uma alternativa para o tratamento do AAA em pacientes com transplante renal.

Endovascular treatment of traumatic dissection of the thoracic aorta - series of 16 cases.

BACKGROUND: Aortic injuries caused by blunt chest traumas have high pre-hospital and emergency mortality. The endovascular approach is one option for treatment of these injuries, but many outcomes related to this approach remain unknown. OBJECTIVES: The aim of this study is to describe a specialist trauma center's experience with endovascular treatment of cases like these. METHODS: This is a descriptive study based on review of the electronic medical records of patients who had suffered from blunt thoracic aorta trauma and were seen at a hospital specializing in trauma cases in the city of Curitiba (Paraná, Brazil). RESULTS: Sixteen patients were included in the study. All patients were traffic accident victims and 75% of the accidents were the result of vehicle collisions. Aortic lesions ranged from grade I to IV and the majority had grade II lesions (50%). All patients underwent endovascular treatment with endografts, an average of 71 hours after the trauma. Two patients died, both from causes unrelated to their aortic injuries. During follow-up, only two patients presented complications (endoleak and progression of the dissection). CONCLUSIONS: The endovascular method is a viable alternative for treatment of blunt trauma thoracic aortic injuries. Randomized and controlled studies are needed to provide evidence to support indication of this method to treat this type of injury.

Endovascular treatment of penetrating thoracic aorta injury - case report.

In the current scenario, traumas with violent causes are responsible for large numbers of cases. Among these, thoracic aorta injury caused by penetrating trauma is a cause of elevated morbidity and mortality, demanding adequate diagnosis, and can now often be repaired using endovascular procedures. This treatment method has proven to be safer, with a lower rate of complications than open surgical procedures. After endovascular repair, it is necessary to conduct continuous monitoring of the patient's health and correct any complications related to the procedure that may emerge. The objective of this article is to describe a case of penetrating trauma of the thoracic aorta that was treated endovascularly, since the literature predominantly covers blunt trauma injuries.

Manejo conservador de choque hemorrágico por ruptura de angiomiolipoma renal: relato de caso / Nonoperative management of hemorrhagic shock due to renal angiomyolipoma rupture: a case report

O angiomiolipoma renal é um tumor benigno e incomum, que cursa com complicações variadas de modo agudo e crônico. Uma de suas manifestações mais dramáticas é a ruptura tumoral, que pode cursar com choque hemorrágico grave. Este relato de caso descreve um episódio de sangramento de grande monta de angiomiolipoma renal, previamente desconhecido, devido à um trauma contuso de baixa energia, que foi manejado com sucesso de modo conservador, utilizando protocolo análogo ao do tratamento não cirúrgico de lesões traumáticas de orgãos intra-abdominais, em um hospital de trauma de referência no Brasil

The renal angiomyolipoma is a benign and rare tumor, that may evolve with different types of acute and chronic complications. One of its most dramatic manifestations is the tumoral rupture, that may cause grave hemorrhagic shock. This case report describes an episode of large amount bleeding of an previously unknown renal angiomyolipoma, due to a low energy blunt trauma, that was successfully managed in a conservative way, using a protocol analogous to the one of non operative management of traumatic lesions of intra abdominal organs, in a reference trauma center in Brasil

Abordagem endovascular de lesão de aorta torácica penetrante - relato de caso / Endovascular treatment of penetrating thoracic aorta injury - case report

Resumo O cenário atual do trauma por causas violentas tem apresentado um elevado número de casos. Entre eles, a lesão de aorta torácica por trauma penetrante é uma condição de elevada morbimortalidade que exige diagnóstico adequado e que, nos últimos anos, tem sido corrigida com procedimentos endovasculares. Essa modalidade de tratamento se mostra mais segura, com menor número de complicações em relação ao procedimento cirúrgico aberto. Após a realização da abordagem endovascular, há necessidade de acompanhamento contínuo, que visa monitorar as condições de saúde do paciente e corrigir possíveis complicações relacionadas ao procedimento. O objetivo deste artigo é relatar um caso de traumatismo penetrante de aorta torácica, tratado por via endovascular, visto que a literatura aborda predominantemente as lesões por trauma contuso.

Tratamento endovascular de dissecção traumática de aorta torácica - série de 16 casos / Endovascular treatment of traumatic dissection of the thoracic aorta - series of 16 cases

Resumo Contexto As lesões de aorta nos traumatismos torácicos fechados possuem alta mortalidade pré-hospitalar e no serviço de emergência. O tratamento endovascular é um método de escolha para o tratamento dessas lesões; entretanto, muitos resultados em relação a essa abordagem permanecem desconhecidos. Objetivos O objetivo deste trabalho é descrever a experiência no tratamento endovascular de lesões traumáticas de aorta torácica em um centro de referência em trauma. Métodos Este trabalho trata-se de estudo descritivo realizado através da revisão de prontuários eletrônicos de pacientes vítimas de trauma contuso de aorta torácica, atendidos em um hospital de referência em trauma na cidade de Curitiba (Paraná, Brasil). Resultados Dezesseis pacientes foram incluídos no estudo. Todos os pacientes foram vítimas de acidente de trânsito, sendo que 75% dos acidentes ocorreram por colisão entre veículos. As lesões de aorta variaram de Grau I a IV, e a maioria dos pacientes apresentou lesão de grau II (50%). Todos os pacientes foram submetidos a terapia endovascular com implante de endoprótese sendo realizado em média 71 horas após o trauma. Dois pacientes evoluíram a óbito, porém de causas não relacionadas à lesão de aorta. Durante o seguimento, apenas dois pacientes apresentaram complicações (endoleak e progressão da dissecção). Conclusões O método endovascular é uma alternativa viável no tratamento de lesões de aorta torácica por trauma contuso. São necessários estudos randomizados e controlados a fim de reforçar a indicação desse método como terapia para esse tipo de lesão.

Psychological aspects and quality of life in Medical Residency. / Aspectos psicológicos e qualidade de vida na Residência Médica.

OBJECTIVE: to evaluate the perception of quality of life among residents in the first year of Medical Residency compared to the one among residents in other years of training, given the importance of this issue in health. METHODS: a comparative and cross-sectional analytical study performed from February to April 2016 in a reference tertiary trauma hospital in Brazil. Resident physicians were voluntarily submitted to an online questionnaire on quality of life (called WHOQOL-BREF), validated by World Health Organization (WHO). They were divided into two groups: first year of residency (R1) and other years of residency. RESULTS: ninety-seven residents of several medical specialties answered the questionnaire. Of these, 59 were men and 38 were women. The mean age was 27.7 years. First-year residents accounted for 49.5% of the interviewees. Overall, quality of life was considered regular in both groups. In relation to psychological domain, there was a significant difference between the R1 group (with worse scores in this domain) and the non-R1 group (p<0.0000001). CONCLUSION: first-year residents' quality of life is worse than the one of the residents from other years, having a significant variation of positive feelings, learning capacity, memory, thought and concentration, self-esteem, body image and appearance, and negative feelings.

OBJETIVO: avaliar a percepção de qualidade de vida entre residentes no primeiro ano de Residência Médica em relação aos residentes de outros anos, dada a importância dessa questão na saúde. MÉTODOS: estudo comparativo, transversal e analítico realizado no período de fevereiro a abril de 2016, realizado em um hospital de trauma terciário de referência do Brasil. Médicos residentes foram submetidos voluntariamente ao questionário validado da Organização Mundial de Saúde (OMS) sobre qualidade de vida, o WHOQOL-BREF, com preenchimento online. Os residentes foram divididos em dois grupos: primeiro ano de residência (R1) e outros anos de residência. RESULTADOS: noventa e sete residentes de diversas especialidades médicas responderam ao questionário. Desses, 59 eram homens e 38, mulheres. A média de idade foi de 27,7 anos. Residentes do primeiro ano representaram 49,5% dos entrevistados. A qualidade de vida de maneira global foi considerada regular em ambos os grupos. Em relação ao domínio psicológico, houve diferença significativa entre o R1 (este, com piores escores neste domínio) e os demais anos de residência (p<0,0000001). CONCLUSÃO: a qualidade de vida dos residentes do primeiro ano é pior em relação aos demais, tendo uma variação significativa de sentimento positivo, capacidade de aprender, memória, pensamento e concentração, autoestima, imagem corporal e aparência e sentimentos negativos em relação aos médicos residentes dos outros anos.

Chest tube simulator: development of low-cost model for training of physicians and medical students. / Simulador de dreno de tórax: desenvolvimento de modelo de baixo custo para capacitação de médicos e estudantes de medicina.

OBJECTIVE: by using a 3D printer, to create a low-cost human chest cavity simulator that allows the reproduction of the closed chest drainage technique (CCD), comparing its effectiveness with that of the animal model. METHODS: it was made a 3D printing of the bony framework of a human thorax from a chest computerized tomography scan. After printing the ribs, we performed tests with several materials that contributed to form the simulation of the thoracic cavity and pleura. An experimental, randomized, and controlled study, comparing the efficacy of the simulator to the efficacy of the animal model, was then carried out in the teaching of CCD technique for medical students, who were divided into two groups: animal model group and simulator model group, that trained CCD technique in animals and in the simulator model, respectively. RESULTS: the chest reconstruction required anatomical knowledge for tomography analysis and for faithful 3D surface editing. There was no significant difference in the safety of performing the procedure in both groups (7.61 vs. 7.73; p=0.398). A higher score was observed in the simulator model group for "use as didactic material" and "learning of the chest drainage technique", when compared to the animal model group (p<0.05). CONCLUSION: the final cost for producing the model was lower than that of a commercial simulator, what demonstrates the feasibility of using 3D printing for this purpose. In addition, the developed simulator was shown to be equivalent to the animal model in relation to the simulation of the drainage technique for practical learning, and there was preference for the simulator model as didactic material.

OBJETIVO: criar, em impressora 3D, um simulador de baixo custo de caixa torácica humana que permita a reprodução da técnica de drenagem fechada de tórax (DFT) comparando sua eficácia com a do modelo animal. MÉTODOS: foi realizada impressão 3D do arcabouço ósseo de um tórax humano a partir de uma tomografia de tórax. Após a impressão das costelas, foram realizados testes com diversos materiais que contribuíram para formar a simulação da caixa torácica e da pleura. Foi, então, realizado um estudo experimental, randomizado e controlado comparando sua eficácia ao modelo animal no ensino da DFT para estudantes de medicina, que foram divididos em dois grupos: Grupo Modelo Animal e Grupo Modelo Simulador, que treinaram DFT em animais e no modelo simulador, respectivamente. RESULTADOS: a reconstrução do tórax exigiu o conhecimento anatômico para análise da tomografia e para edição fiel da superfície 3D. Não houve diferença significativa quanto à segurança de realizar o procedimento entre os grupos (7,61 vs. 7,73; p=0,398). Foi observada maior pontuação no grupo modelo simulador para uso como material didático e aprendizado da técnica de drenagem torácica quando comparado ao grupo modelo animal (p<0,05). CONCLUSÃO: o custo final para a confecção do modelo foi inferior ao de um simulador comercial, o que demonstra a viabilidade do uso da impressão 3D para esse fim. Além disso, o simulador desenvolvido se mostrou equivalente ao modelo animal quanto à simulação da técnica de drenagem para aprendizado prático e houve preferência pelo modelo simulador como material didático.

Não houve diferença significativa quanto à segurança de realizar o procedimento entre os grupos (7,61 vs. 7,73; p=0,398). Foi observada maior pontuação no grupo modelo simulador para uso como material didático e aprendizado da técnica de drenagem torácica quando comparado ao grupo modelo animal (p<0,05). Conclusão: o custo final para a confecção do modelo foi inferior ao de um simulador comercial, o que demonstra a viabilidade do uso da impressão 3D para esse fim. Além disso, o simulador desenvolvido se mostrou equivalente ao modelo animal quanto à simulação da técnica de drenagem para aprendizado prático e houve preferência pelo modelo simulador como material didático.

ABSTRACT Objective: by using a 3D printer, to create a low-cost human chest cavity simulator that allows the reproduction of the closed chest drainage technique (CCD), comparing its effectiveness with that of the animal model. Methods: it was made a 3D printing of the bony framework of a human thorax from a chest computerized tomography scan. After printing the ribs, we performed tests with several materials that contributed to form the simulation of the thoracic cavity and pleura. An experimental, randomized, and controlled study, comparing the efficacy of the simulator to the efficacy of the animal model, was then carried out in the teaching of CCD technique for medical students, who were divided into two groups: animal model group and simulator model group, that trained CCD technique in animals and in the simulator model, respectively. Results: the chest reconstruction required anatomical knowledge for tomography analysis and for faithful 3D surface editing. There was no significant difference in the safety of performing the procedure in both groups (7.61 vs. 7.73; p=0.398). A higher score was observed in the simulator model group for "use as didactic material" and "learning of the chest drainage technique", when compared to the animal model group (p<0.05). Conclusion: the final cost for producing the model was lower than that of a commercial simulator, what demonstrates the feasibility of using 3D printing for this purpose. In addition, the developed simulator was shown to be equivalent to the animal model in relation to the simulation of the drainage technique for practical learning, and there was preference for the simulator model as didactic material.

Dissecção aórtica de tipo B de Stanford: relato de caso e revisão de literatura / Stanford B aortic dissection: case report and literature review

O complexo tratamento de dissecção da aorta ainda apresenta controvérsias devido à gravidade do caso e à necessidade de individualização da terapêutica. A gravidade relaciona-se ao difícil diagnóstico pelas queixas inespecíficas e pelas graves complicações inerentes à evolução da doença (ruptura aórtica, síndrome de má perfusão, dissecção retrógrada, dor ou hipertensão refratária). Este relato apresenta um homem de 61 anos, tabagista e hipertenso mal controlado, que evoluiu para dissecção aórtica de tipo B de Stanford. Foi abordado através de técnica endovascular com uso de endoprótese com stent para tratamento do caso após falha do tratamento medicamentoso. O tratamento endovascular mostrou-se uma ferramenta eficaz para o tratamento definitivo, com boa taxa de sobrevida ao final do primeiro ano após o procedimento

Complex treatment of aortic dissection is still a controversial subject because of the severity of these cases and the need to treat on a case-by-case basis. Severity is related to the difficulty of diagnosis caused by nonspecific complaints and by the serious complications inherent to disease progression (aortic rupture, hypoperfusion syndrome, retrograde dissection, refractory hypertension or pain). This article reports the case of a 61-year-old male smoker with poorly controlled hypertension who suffered a Stanford type B aortic dissection. After drug-based treatment failed, the patient was treated using endovascular techniques to place an endoprosthesis with stenting. Endovascular treatment is proving to be an effective tool for definitive treatment, with a good survival rate at the end of the first year after the procedure
