Abstract Objective: To compare high and low-fidelity simulations for the recognition of respiratory distress and failure in urgency and emergency pediatric scenarios. Methods: 70 fourth-year medical students were randomly distributed in high and low-fidelity groups and simulated different types of respiratory problems. Theory tests, performance checklists, and satisfaction and self-confidence questionnaires were used in the assessment. Face-to-face simulation and memory retention was applied. The statistics were evaluated by averages and quartiles, Kappa, and generalized estimating equations. The p-value was considered 0.05. Results: In the theory test there was an increase in scores in both methodologies (p < 0.001 ); in memory retention (p = 0.043) and at the end of the process the high-fidelity group had better results. The performance in the practical checklists was better after the second simulation (p > 0,05). The high-fidelity group felt more challenged in both phases (p = 0.042; p = 0.018) and showed greater self-confidence to recognize changes in clinical conditions and in memory retention (p = 0.050). The same group, in relation to the hypothetical real patient to be treated in the future, felt better confident to recognize respiratory distress and failure (p = 0.008; p = 0.004), and better prepared to make a systematic clinical evaluation of the patient in memory retention (p = 0.016). Conclusion: The two levels of simulations enhance diagnostic skills. High fidelity improves knowledge, leads the student to feel more challenged and more self-confident in recognizing the severity of the clinical case, including memory retention, and showed benefits regarding self-confidence in recognizing respiratory distress and failure in pediatric cases.

RESUMO CONTEXTO: A gastrostomia endoscópica percutânea (GEP) é uma importante opção de nutrição enteral para crianças e adultos, sendo considerada uma técnica segura, eficaz e vantajosa em comparação às outras vias de alimentação complementar. Permite a alimentação contínua, a alimentação em pacientes com distúrbios de deglutição de causa neurológica ou outros, a administração de dietas ou medicamentos não palatáveis, todos com baixos índices de complicações e mortalidade. OBJETIVO: Avaliar as principais indicações e complicações de pacientes pediátricos submetidos à GEP e o impacto no estado nutricional de pacientes submetidos à GEP para suplementação nutricional, comparando peso, índice de massa corporal (IMC) e estatura com referências da Organização Mundial de Saúde. MÉTODOS: Estudo observacional e retrospectivo de 152 crianças e adolescentes submetidos à GEP, no período de janeiro/2003 a dezembro/2018. Foram incluídos pacientes até 18 anos de idade na época do procedimento. As complicações relacionadas ao procedimento foram divididas em menores e maiores. Pacientes com indicação de GEP para suplementação nutricional foram avaliados quanto ao ganho de peso, altura e IMC, por meio do escore Z no dia do procedimento e 6 meses; 1 ano; e 2 anos após o procedimento. RESULTADOS: As indicações para GEP foram distúrbio de deglutição de causa neurológica (67,1%), necessidade de suplementação nutricional (25%), distúrbio de deglutição de origem mecânica (6,6%), e indicação de descompressão gástrica (1,3%). Complicações menores ocorreram em 57,8% dos pacientes e complicações maiores em 9,8%. A técnica de tração correspondeu a 92,1% e a punção, 7,9%. A taxa de mortalidade foi de 1,3%. Trinta e oito pacientes tinham indicação de suplementação nutricional. Nestes, houve aumento gradativo tanto do IMC quanto do peso, com variação estatisticamente significativa da mediana P=0,0340 e P=0,0105, respectivamente, mais evidente nos pacientes renais crônicos. A altura não variou significativamente (P=0,543). CONCLUSÃO: A GEP mostrou-se uma opção vantajosa como forma auxiliar de alimentação em pacientes pediátricos, tendo como principais indicações a disfagia de causa neurológica e a necessidade de suplementação nutricional, com baixa prevalência de complicações maiores e mortalidade. Este estudo também mostrou a importância da GEP em pacientes com necessidade de suplementação nutricional, possibilitando a passagem dos pacientes desnutridos para escores nutricionais de peso adequados à idade.

ABSTRACT BACKGROUND: Percutaneous endoscopic gastrostomy (PEG) is an important option for enteral nutrition for both children and adults. It is considered a safe, effective, and advantageous technique in comparison to other complementary feeding routes. It allows continuous feeding, the feeding of patients with swallowing disorders due to neurological causes or others, and the administration of non-palatable diets or medications, all with low rates of complications and mortality. OBJECTIVE: This study aimed to evaluate the main indications and complications of PEG in pediatric patients. In addition, the impact on the nutritional status of patients undergoing PEG was also compared with weight, body mass index (BMI), and height according to references from the World Health Organization. METHODS: This observational and retrospective study included 152 children and adolescents who underwent PEG between January/2003 and December/2018. Patients up to 18 years of age at the time of the procedure were included. Complications related to the procedure were classified as minor or major. Patients with PEG indication for nutritional supplementation were evaluated for weight gain, height, and BMI, using the Z score at the day of the procedure and six months, 1 year, and 2 years after the procedure. RESULTS: Indications for PEG were: swallowing disorder of neurological cause (67.1%), need for nutritional supplementation (25%), swallowing disorder of mechanical origin (6.6%), and indication of gastric decompression (1.3%). Minor complications occurred in 57.8% of patients and major complications in 9.8% of patients. The traction technique corresponded to 92.1% and puncture to 7.9%. The death rate was 1.3%. Thirty-eight patients had an indication for nutritional supplementation. In these patients, there was a gradual increase in both BMI and weight, reaching statistically significant differences (P=0.0340 and P= 0.0105, respectively). These differences were more evident in chronic renal disease patients. Height did not vary significantly (P=0.543). CONCLUSION: PEG proved to be an advantageous option as an auxiliary feeding method in pediatric patients. Dysphagia of neurological origin was the main indication followed by the need for nutritional supplementation. PEG has low frequency of major complications and mortality. This study also showed the importance of PEG in patients who need nutritional supplementation, as it enabled patients to move from undernutrition to normal weight ranges.

RESUMO CONTEXTO: Hepatite autoimune (HAI) é uma doença hepática inflamatória crônica, rara, associada à perda da tolerância imunológica aos auto-antígenos. A susceptibilidade à HAI é parcialmente determinada pela presença de genes relacionados ao antígeno leucocitário humano (HLA), principalmente variantes alélicas do DRB1. OBJETIVO: O objetivo deste estudo foi investigar a frequência de polimorfismos no gene HLA-DRB1 em crianças e adolescentes com HAI tipo 1 e HAI tipo 1 associada à colangite autoimune, em comparação com indivíduos saudáveis pareados por sexo e idade (grupo controle). MÉTODOS: Este é um estudo transversal de 25 pacientes pediátricos com diagnóstico de HAI tipo 1 e 18 com HAI associada à colangite autoimune. Cinquenta e sete indivíduos saudáveis foram incluídos como controles. Os polimorfismos do gene HLA-DRB1 foram avaliados por PCR e incluíram HLA-DRB1*03, HLA-DRB1*04, HLA-DRB1*07 e HLA-DRB1*13. RESULTADOS: Nossos resultados mostraram que a presença do alelo HLA-DRB1*13 aumentou a chance de colangite autoimune (OR=3,96; IC 1,07 a 14,61; P=0,04). O HLA-DRB1*04 e o HLA-DRB1*07 não apresentam associação com a HAI e colangite autoimune no grupo de pacientes mais jovens. CONCLUSÃO: Este trabalho demonstra uma associação dos principais polimorfismos no gene HLA-DRB1 à HAI com ou sem colangite na população brasileira.

ABSTRACT BACKGROUND: Autoimmune hepatitis (AIH) is a rare chronic inflammatory liver disease associated with a loss of immunological tolerance to self-antigens. Susceptibility to AIH is partially determined by the presence of genes related to human leukocyte antigen (HLA), mainly allelic variants of DRB1. OBJECTIVE: The purpose of this study was to investigate the frequencies of the polymorphisms in HLA-DRB1 gene in children and adolescents with type 1 AIH and type 1 AIH overlap syndrome with autoimmune cholangitis (overlap syndrome, OS) in comparison to healthy sex and age-matched individuals (control group). METHODS: This is a cross-sectional study of 25 pediatric patients diagnosed with type 1 AIH and 18 with OS. Fifty-seven healthy individuals were included as controls. The polymorphisms of the HLA-DRB1 gene were evaluated by PCR and included HLA-DRB1*03, HLA-DRB1*04, HLA-DRB1*07, and HLA-DRB1*13. RESULTS: Our results showed that the presence of the allele HLA-DRB1*13 increased the chance of autoimmune cholangitis (OR=3.96, CI 1.07 to 14.61, P=0.04). The HLA-DRB1*04 and HLA- DRB1*07 have no association with the AIH and autoimmune cholangitis in a young sample. CONCLUSION: This work demonstrates an association of the main polymorphisms in the HLA-DRB1 gene to AIH with or without cholangitis in a Brazilian sample.
