ABSTRACT

ABSTRACT Objective: DATASUS is the Brazilian Public Unified Health System (SUS) department responsible for providing health data that are used as a primary source of data in several studies on surgery and surgical specialties although its main limitations have not been previously reviewed. The objective of this work is to synthesize information from studies on surgery that used DATASUS systems as a data source and to identify the main gaps in this platform. Methods: a scoping review was conducted according to the PRISMA-ScR method to identify papers on surgery, and other surgical specialties, that used the DATASUS platform as a primary data source. No restrictions were imposed regarding the type of study or year of publication. Grounded Theory was used to analyze the content of the articles. Results: 248 works were initially analyzed and 47 were included in the final analysis of this study. The original articles included were published between 2009 and 2022 and the majority (12.76%, n=6) were published in the Journal of the Brazilian College of Surgeons. Retrospective studies (40.43%, n=19) were the most common type of study found. Content analysis of the articles identified four predominant domains in the scientific literature about the limitations of using DATASUS in surgical research: lack of data, reliability, precision and data integration. Conclusion: the information systems available in DATASUS are the largest source of information about the SUS, but the scientific literature on the quality of data available in these systems remains scarce and studies aimed at measuring this metric are necessary.


RESUMO Objetivo: o DATASUS é o departamento do SUS responsável por disponibilizar dados de saúde que são empregados como fonte primária de dados em diversos estudos sobre cirurgia e especialidades cirúrgicas, embora principais limitações não tenham sido revisadas anteriormente. O objetivo deste trabalho é sintetizar as informações de estudos sobre cirurgia que utilizaram sistemas do DATASUS como fonte de dados, identificando as principais lacunas. Métodos: uma revisão de escopo foi conduzida de acordo com o método PRISMA-ScR para a identificação de trabalhos sobre cirurgia, e outras especialidade cirúrgicas, que utilizaram a plataforma DATASUS como fonte primária de dados. Nenhuma restrição foi imposta em relação ao tipo de estudo ou ano de publicação. A Teoria Fundamentada em Dados foi utilizada para a análise do conteúdo dos artigos. Resultados: 248 trabalhos foram inicialmente analisados e 47 foram incluídos na análise final deste estudo. Os artigos originais incluídos foram publicados entre 2009 e 2022, maioria (12,76%, n=6) foi publicada na Revista do Colégio Brasileiro de Cirurgiões. Estudos retrospectivos (40,43%, n=19) foram o tipo de estudo mais comum encontrado. A análise dos artigos identificou quatro domínios predominantes na literatura científica acerca das limitações do uso de DATASUS em pesquisas em cirurgia: falta de dados, confiabilidade, precisão e integralização dos dados. Conclusão: os sistemas de informação dispostos no DATASUS constituem a maior fonte de informações sobre o SUS, porém a literatura científica sobre a qualidade dos dados dispostos nestes sistemas permanece escassa e trabalhos direcionados a mensurar essa métrica são necessários.

ABSTRACT

Abstract Background Despite significant improvements in outcomes, traumatic arterial limb injuries remain a significant cause of limb loss and mortality. Objectives This study sought to identify predictors of mortality and major amputation in patients undergoing revascularization after femoropopliteal arterial trauma. Methods This was a retrospective review of a trauma registry from an urban trauma center in Brazil. All patients admitted to our hospital with a femoropopliteal arterial injury from November 2012 to December 2017 who underwent vascular reconstruction were included. Univariate analyses and logistic regression analyses were conducted to identify factors independently associated with the primary outcome of amputation and the secondary outcome of mortality. Results Ninety-six patients were included. Eleven patients (11.5%) had an amputation and 14 (14.6%) died. In the logistic regression model for amputation, patients with ischemia duration greater than 6 hours were approximately 10 times more likely to undergo an amputation compared to those with ischemia duration less than or equal to 6 hours (adjusted odds ratio (AOR) [95% confidence interval (CI)]: 9.6 [1.2-79.9]). The logistic regression model for mortality revealed that patients with ischemia duration greater than 6 hours were approximately 6 times more likely to die compared to those with ischemia duration less than or equal to 6 hours (AOR [95% CI]: 5.6 [1.3 to 24.7). Conclusions Ischemia duration remains the most important factor independently associated with limb loss and mortality for patients undergoing femoropopliteal arterial revascularization after traumatic injuries. Physiological status on admission and trauma scores are also important.


Resumo Contexto As lesões arteriais traumáticas de membros ainda permanecem uma causa significativa de perda de membros e mortalidade, apesar de melhorias significativas observadas nos resultados após a ocorrências dessas lesões. Objetivos Este estudo buscou identificar preditores de mortalidade e amputações em pacientes submetidos à revascularização após trauma arterial femoropoplíteo. Métodos Esta é uma revisão de um Registro de Trauma Vascular. Todos os pacientes com lesão arterial femoropoplítea internados em nosso hospital de novembro de 2012 a dezembro de 2017 e submetidos a reconstrução vascular foram incluídos. Análises univariadas, seguidas de análises de regressão logística, foram realizadas para identificar fatores independentemente associados com os resultados primários de amputação e mortalidade. Resultados Foram incluídos 96 pacientes, com média de 27 anos. O Revised Trauma Score (RTS) foi, em média, 7,152; já o Injury Severity Score (ISS) foi, em média, 15. Onze pacientes (11,5%) tiveram amputação, e 14 pacientes (14,6%) morreram. Observou-se que pacientes com o tempo de isquemia maior que 6 horas apresentaram aproximadamente 10 vezes mais chance de amputação do que aqueles com tempo igual ou menor que 6 horas (intervalo de confiança de 95% [IC95%]: 1,2 a 79,9). O tempo de isquemia maior que 6 horas aumentou em aproximadamente 6 vezes a chance de mortalidade (IC95%: 1,26 a 24,77). A instabilidade hemodinâmica aumentou em 9 vezes a chance de mortalidade (IC95%: 2,36 a 36,67). Conclusões O tempo de isquemia continua sendo o fator mais importante independentemente associado a amputação e óbito em pacientes submetidos à revascularização arterial femoropoplítea após traumas. O estado fisiológico e os escores de trauma são importantes.

ABSTRACT

Resumo Contexto Modelos com animais de médio e grande porte permitem que pesquisadores avaliem a eficácia e a segurança de procedimentos cardiovasculares em sistemas que se assemelham à anatomia humana e podem ser usados para simular cenários para fins de treinamento. Embora modelos suínos tenham sido extensivamente utilizados, muitos fatores fisiológicos e anatômicos permanecem desconhecidos ou apenas superficialmente descritos. Objetivos Descrever a anatomia vascular do suíno por tomografia computadorizada, compará-la à anatomia humana e discutir a aplicação dos modelos porcinos em procedimentos abertos e endovasculares. Métodos Três porcos machos da raça Landrace foram submetidos a tomografia computadorizada. A anatomia vascular de pescoço, tórax, abdome e membros foi analisada e descrita; foram destacadas similaridades e divergências relevantes entre a anatomia vascular de suínos e de humanos e as implicações em procedimentos vasculares nos suínos. Resultados O território carotídeo, o arco aórtico e os ramos terminais da aorta em suínos apresentaram diferenças marcantes quando comparados aos de humanos. Foram detectadas compressões de veias renal e ilíaca comum, ambas à esquerda, semelhantes às encontradas nas síndromes humanas de Nutcracker e May-Thurner. Medidas vasculares (diâmetro, comprimento e ângulos) de diferentes topografias de suínos foram fornecidas. Conclusões Os dados fornecidos podem ser úteis para o planejamento de ensaios pré-clínicos e pesquisa básica, bem como para o refinamento do treinamento cirúrgico usando modelos suínos no campo da cirurgia vascular.


Abstract Background Medium and large animal models allow researchers to evaluate the efficacy and safety of cardiovascular procedures in systems that resemble human anatomy and can be used to simulate scenarios for training purposes. Although porcine models have been used extensively, many physiological and anatomical features remain unknown or only superficially described. Objectives To describe the normal porcine vascular anatomy on computed tomography scans, compare it to human vascular anatomy, and discuss the application of porcine models for open and endovascular procedures. Methods Three male Landrace pigs underwent computed tomography. The vascular anatomy of the neck, thorax, abdomen, and limbs was analyzed and described; relevant similarities and differences between porcine and human vascular anatomies and the implications for vascular procedures in pigs are highlighted. Results The carotid territory, aortic arch, and terminal aorta branches all show marked differences in pigs compared to their human counterparts. Compressions of both left renal and common iliac veins were detected, analogous to those seen in human Nutcracker and May-Thurner syndromes. Vascular measurements (diameters, lengths, and angles) of several different porcine territories are presented. Conclusions The data presented should be useful for planning preclinical trials and basic research and for refining surgical training using porcine models in vascular fields.

ABSTRACT

Abstract Purpose: To describe the anatomy of the swine urinary system using computed tomography and to discuss the role of this animal as an experimental model for urological procedures. Methods: Three male Landrace pigs underwent computed tomography and the anatomy of the urinary system and renal circulation was analyzed and described. Results: In all animals, 2 kidneys, 2 ureters and one bladder were identified. Each kidney presented a single renal artery vascularization, with a mean diameter on the right of 4.45 and 5.31 mm on the left (p < 0.0001) and single renal vein drainage, with a mean diameter on the right of 5.78 and 5.82 mm on the left (p = 0.0336). The average renal length was 9.85 cm on the right and 10.30 cm on the left (p < 0.0001). The average renal volume was 113.70 cm3 on the right and 109.70 cm3 on the left (p < 0.0001). The average length of the ureter was 19.78 cm on the right and 22.08 cm on the left (p < 0.0001). The average bladder volume was 423.70 cm3. Conclusions: The data obtained show similarities with human anatomy, suggesting the viability of the swine model for planning preclinical trials, basic research, refinement in experimental surgery and surgical training for urological procedures.

ABSTRACT

OBJECTIVE: To develop and validate a questionnaire to assess the knowledge of mechanical ventilation among final-year medical students in Brazil. METHODS: A cross-sectional study conducted between October 2015 and October 2017 involving 554 medical students was carried out to develop a questionnaire for assessing knowledge on mechanical ventilation. Reproducibility was evaluated with the intraclass correlation coefficient, internal consistency was evaluated with Cronbach's alpha, and construct validation was evaluated with a tetrachoric exploratory factor analysis. To compare the means of the competences among the same type of assessment tool, the nonparametric Friedman test was used, and the identification of the differences was obtained with Dunn-Bonferroni tests. RESULTS: The final version of the questionnaire contained 19 questions. The instrument presented a clarity index of 8.94±0.83. The value of the intraclass correlation coefficient was 0.929, and Cronbach's alpha was 0.831. The factor analysis revealed five factors associated with knowledge areas regarding mechanical ventilation. The final score among participants was 24.05%. CONCLUSION: The instrument has a satisfactory clarity index and adequate psychometric properties and can be used to assess the knowledge of mechanical ventilation among final-year medical students in Brazil.

Amputação foi necessária em 6,9% e a mortalidade foi 7,93%. Conclusão: distâncias superiores a 200km foram associadas à internação prolongada e maior probabilidade de amputação de membros. Foi encontrada correlação significativa entre a ocorrência de óbito e o fato de haver lesão arterial, lesão vascular na topografia cervical e lesão vascular na topografia torácica.


ABSTRACT Objective: to evaluate the epidemiological data of patients operated on due to vascular trauma at a referral hospital in Pará state, to determine the variables that increase the risk of death, and to make a comparative analysis with the results previously published by the same institution. Methods: an analytical retrospective study was performed through data collection from patients operated due to vascular injuries, between March 2013 and March 2017. Demographic and epidemiological data, such as the mechanism and topography of the lesion, distance between the trauma site and the hospital, and type of treatment and complications, were analyzed. Multivariate analysis and logistic regression studies were performed, to evaluate significant dependence between some variables and death occurrence. Results: two hundred and eighty eight patients with 430 lesions were studied; 92.7% were male, 49.7% were between 25 and 49 years old; 47.2% of all injuries were caused by firearm projectiles; 47.2% of the lesions were located in the upper limbs, 42.7% in the lower limbs, 8% in the cervical region, 3.1% in the thoracic region, and 0.7% in the abdominal region; 52.8% of the patients were hospitalized for seven days or less. Amputation was required in 6.9% of patients and there was mortality in 7.93% of the cases. Conclusion: distances greater than 200km were associated with prolonged hospitalization and greater probability of limb amputation. Significant correlation between death occurrence and arterial injury, vascular injury in the cervical region, and vascular injury in the thoracic region was found.

ABSTRACT

Abstract Purpose: To evaluate severity and built a pilot of a national databank about pediatric trauma and to determine its severity. Methods: Prospective study of unintentional pediatric trauma in five hospitals in the city of São Paulo, Brazil. Results: 916 patients in 4 months. 61.5% of traumatized children were male, average 6.5 years. 48. 4% were falls. Most families had an average monthly income less than three minimum wages. 42% of accidents occurred at home. 18.9% of children were alone. 59,8% of parents thought it could be prevented. 26.5% of children had previous accidents. GCS was severe: 5 patients, moderate: 8 patients. 21 patients were intubated (2.4%), RTS <7 in 10.2%, PTS<8 in 3.6%. 8.5% patients were considered severe, which was related to falls (p=0.001); sports (p=0.045); pedestrian (p=0.006); child education (p=0.015) and cared by male (p=0.007). Conclusions: Severity occurred in 8.5% and was associated to falls, sports, traffic, child education, and cared by male. Simple preventive measures could have prevented most of the accidents. The tested tool for details was successful and can be used throughout the country.

ABSTRACT

ABSTRACT Background: The treatment of neuroblastoma is dependent on exquisite staging; is performed postoperatively and is dependent on the surgeon's expertise. The use of risk factors through imaging on diagnosis appears as predictive of resectability, complications and homogeneity in staging. Aim: To evaluate the traditional resectability criteria with the risk factors for resectability, through the radiological images, in two moments: on diagnosis and in pre-surgical phase. Were analyzed the resectability, surgical complications and relapse rate. Methods: Retrospective study of 27 children with abdominal and pelvic neuroblastoma stage 3 and 4, with tomography and/or resonance on the diagnosis and pre-surgical, identifying the presence of risk factors. Results: The mean age of the children was 2.5 years at diagnosis, where 55.6% were older than 18 months, 51.9% were girls and 66.7% were in stage 4. There was concordance on resectability of the tumor by both methods (INSS and IDRFs) at both moments of the evaluation, at diagnosis (p=0.007) and post-chemotherapy (p=0.019); In this way, all resectable patients by IDRFs in the post-chemotherapy had complete resection, and the unresectable ones, 87.5% incomplete. There was remission in 77.8%, 18.5% relapsed and 33.3% died. Conclusions: Resectability was similar in both methods at both pre-surgical and preoperative chemotherapy; preoperative chemotherapy increased resectability and decreased number of risk factors, where the presence of at least one IDRF was associated with incomplete resections and surgical complications; relapses were irrelevant.


RESUMO Racional: O tratamento do neuroblastoma é dependente de estadiamento primoroso, realizado no pós-cirúrgico e dependente da expertise do cirurgião. O uso de fatores de risco através da imagem ao diagnóstico surge como preditivo de ressecabilidade, complicações e homogeneidade no estadiamento. Objetivos: Avaliar o critério de ressecabilidade tradicional com os fatores de risco para ressecabilidade, através das imagens radiológicas, em dois momentos no diagnóstico e no pré-cirúrgico analisando a ressecabilidade, complicações cirúrgicas e índice de recidiva. Métodos: Estudo retrospectivo em 27 crianças com neuroblastoma estádios 3 e 4 em abdome e pelve, e com tomografia e/ou ressonância no diagnóstico e pré-cirúrgico, identificando-se a presença de fatores de risco. Resultados: A idade média das crianças foi de 2,5 anos ao diagnóstico, onde 55,6% estavam acima dos 18 meses, 51,9% eram meninas e 66,7% tinham estádio 4. Houve concordância da ressecabilidade do tumor pelos dois métodos avaliados (INSS e IDRFs) e em ambos os momentos da avaliação, ao diagnóstico (p=0,007) e pós-quimioterapia (p=0,019). Desta forma todos pacientes ressecáveis por IDRFs no pós-quimioterapia tiveram ressecção completa; já nos irressecáveis, 87,5% tiveram ressecção incompleta. Houve remissão em 77,8%, 18,5% recaíram e 33,3% morreram. Conclusões: Aressecabilidade foi semelhante em ambos os métodos tanto no diagnóstico como no pré-cirúrgico. A quimioterapia pré-operatória aumentou a ressecabilidade e diminuição do número de fatores de risco, onde a presença de ao menos um IDRF associou-se às ressecções incompletas e complicações cirúrgicas. As recidivas foram irrelevantes.

ABSTRACT

OBJECTIVES: The purpose is to study the effects of hyperbaric oxygen therapy and autologous platelet concentrates in healing the fibula bone of rabbits after induced fractures. METHODS: A total of 128 male New Zealand albino rabbits, between 6-8 months old, were subjected to a total osteotomy of the proximal portion of the right fibula. After surgery, the animals were divided into four groups (n = 32 each): control group, in which animals were subjected to osteotomy; autologous platelet concentrate group, in which animals were subjected to osteotomy and autologous platelet concentrate applied at the fracture site; hyperbaric oxygen group, in which animals were subjected to osteotomy and 9 consecutive daily hyperbaric oxygen therapy sessions; and autologous platelet concentrate and hyperbaric oxygen group, in which animals were subjected to osteotomy, autologous platelet concentrate applied at the fracture site, and 9 consecutive daily hyperbaric oxygen therapy sessions. Each group was divided into 4 subgroups according to a pre-determined euthanasia time points: 2, 4, 6, and 8 weeks postoperative. After euthanasia at a specific time point, the fibula containing the osseous callus was prepared histologically and stained with hematoxylin and eosin or picrosirius red. RESULTS: Autologous platelet concentrates and hyperbaric oxygen therapy, applied together or separately, increased the rate of bone healing compared with the control group. CONCLUSION: Hyperbaric oxygen therapy and autologous platelet concentrate combined increased the rate of bone healing in this experimental model. .

ABSTRACT

OBJECTIVE: To examine the severity of trauma in entrapped victims and to identify risk factors for mortality and morbidity. INTRODUCTION: Triage and rapid assessment of trauma severity is essential to provide the needed resources during prehospital and hospital phases and for outcome prediction. It is expected that entrapped victims will have greater severity of trauma and mortality than non-entrapped subjects. METHODS: A transverse, case-control, retrospective study of 1203 victims of motor vehicle collisions treated during 1 year by the prehospital service in São Paulo, Brazil was carried out. All patients were drivers, comprising 401 entrapped victims (33.3 percent) and 802 non-entrapped consecutive controls (66.7 percent). Sex, age, mortality rates, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), corporal segments, timing of the prehospital care and resource use were compared between the groups. The results were analysed by χ2, Zres, analysis of variance and Bonferroni tests. RESULTS: Entrapped victims were predominantly men (84.8 percent), aged 32±13.1 years, with immediate mortality of 10.2 percent and overall mortality of 11.7 percent. They had a probability of death at the scene 8.2 times greater than that of non-entrapped victims. The main cause of death was hemorrhage for entrapped victims (45.2 percent) and trauma for non-entrapped victims. Of the entrapped victims who survived, 18.7 percent had a severe GCS (OR = 10.62), 12 percent a severe RTS (OR = 9.78) and 23.7 percent were in shock (OR = 3.38). Entrapped victims were more commonly transported to advanced life support units and to tertiary hospitals. CONCLUSION: Entrapped victims had greater trauma severity, more blood loss and a greater mortality than respective, non-entrapped controls.

ABSTRACT

A incidência de trombose venosa profunda (TVP) em crianças (0 a 18 anos) é baixa. O objetivo desse trabalho é estudar uma criança de 12 anos que, após um trauma, apresentou TVP. Atividades de proteína C, proteína S, antitrombina e resistência à proteína C ativada (RPCA) foram analisadas em coagulômetro. O fator V de Leiden (FVL) foi pesquisado. O paciente e seu pai (assintomático até o momento) foram heterozigotos para FVL e sua mãe foi homozigota normal. Concluímos que o FVL associado a outras condições clínicas tende a ser multiplicativo para a ocorrência de trombose, que é multifatorial.


The incidence of deep venous thrombosis (DVT) in children (0-18 years old) is low. The aim of this study was to investigate the case of a 12 year-old child that had DVT after a trauma. Protein C and protein S activities, antithrombin and resistance to activated protein C were analyzed in coagulometer. Factor V Leiden (FVL) was studied. The patient and his father were heterozygotes for FVL. His mother was normal homozygote. We concluded that the presence of FVL associated with other medical conditions tends to multiply the occurrence of thrombosis, which is a multifactorial disease.

ABSTRACT

OBJETIVO: Avaliar o atendimento pré-hospitalar de crianças e adolescentes em São Paulo, avaliar o banco de dados das Unidades de Suporte Básico (UR) e Avançado (USA) e propor um método simples e eficaz para a avaliação da gravidade do trauma pediátrico na fase pré-hospitalar. MÉTODOS: Uma única central do Corpo de Bombeiros (COBOM) coordena todo o atendimento pré-hospitalar em São Paulo. Dois bancos de dados foram analisados para crianças de 0 a 18 anos de idade, entre 1998 e 2001: um das Unidades de Suporte Básico de Vida (UR- bombeiros) e outra de Unidades de Suporte Avançado (USA - médico e bombeiros). Neste período, o Serviço de Atendimento Médico de Urgência do Estado de São Paulo (SAMU) forneceu relatórios médicos de 604 vítimas, enquanto os bombeiros forneceram relatórios de 12.761 vitimas (UR+USA). A classificação do trauma pré-hospitalar pediátrico é baseada na condição fisiológica, mecanismo de trauma e lesões anatômicas das vítimas. A classificação do trauma pré-hospitalar pediátrico foi comparada à Escala de Coma de Glasgow (GCS) e ao Escore de Trauma Revisado (RTS). RESULTADOS: Houve predominância do sexo masculino em ambos bancos de dados. O mecanismo de trauma mais freqüente foi relacionado a transporte, seguido de quedas. A mortalidade foi 1,6% nas Unidades Básicas e 9,6% no Suporte Avançado. Houve associação entre a classificação do trauma pré-hospitalar pediátrico, Escala de Coma de Glasgow (GCS) e ao Escore de Trauma Revisado (RTS) GCS e RTS (p<0,0001). CONCLUSAO: A classificação do trauma pré-hospitalar pediátrico é um método simples e confiável para a avaliação, triagem e recrutamento de recursos para o atendimento pré-hospitalar do trauma pediátrico.

ABSTRACT

OBJETIVO: Estudar a anatomia funcional do fígado, sua segmentaçäo, tendo como referência às estruturas vasculares, venosas, no interior do parênquima. MÉTODOS: Dissecçäo em fígados de cadáveres recentes, identificando, na intimidade dos órgäos, os pedículos portais e as veias hepáticas, definindo, assim, os segmentos hepáticos ou unidades funcionais do fígado. RESULTADOS: Caracterizaçäo anatômica dos segmentos hepáticos, em número de 8, suas estruturas vasculares aferentes e eferentes, orientando ressecções anatômicas, regradas, preservando a vitalidade e funçäo dos segmentos remanescentes. CONCLUSÄO: O conhecimento da anatomia funcional do fígado, baseada na sua segmentaçäo, constitui a base para a moderna cirurgia hepática

ABSTRACT

Introduçao: A ectopia testicular cruzada (ETC) e uma anomalia rara, caracterizada pela descida de um testiculo no canal inguinal do lado oposto. Apresentamos um caso de ectopia cruzada do testiculo direito, tratado por transposicao extraperitoneal da gonada e orquipexia direita. Conclusao: Os conhecimentos embriologicos e os achados cirurgicos sugerem que a ETC seja uma consequencia comum de varios fatores etiologicos, sobretudo fatores mecanicos, e pode causar persistencia do ducto de Muller. Apos extensa revisao da literatura, sugerimos uma classificacao da ETC em 3 tipos: 1- associada somente a hernia inguinal; II- associada a remanescentes mullerianos; III- associada a outras anomalias, sem remanescentes mullerianos. O tratamento inclui orquipexia trans-septal ou transposicao trans-abdominal do testiculo, pesquisa de remanescentes mullerianos e outras anomalias, e seguimento pos-operatorio a longo prazo, devido a resci de malignizacao.
