Abstract Background The objective of this study was to compare HFNC therapy to noninvasive ventilation (NIV/BiPAP) in children with bronchiolitis who developed respiratory failure. We hypothesized that HFNC therapy would not be inferior to NIV. Methods This was a noninferiority open-label randomized single-center clinical trial conducted at a tertiary Brazilian hospital. Children under 2 years of age with no chronic conditions admitted for bronchiolitis that progressed to mild to moderate respiratory distress (Wood-Downes-Férres score

Resumo Fundamento: Seguimento de coorte retrospectiva de 30 anos que se aproxima da história natural dos tumores cardíacos diagnosticados no feto uma vez que nenhum caso foi submetido à interrupção da gestação. Objetivo: Avaliar a morbidade e mortalidade perinatal e em longo prazo em fetos com diagnóstico de tumor cardíaco. Como objetivo secundário avaliar os fatores que influenciaram os resultados perinatais e pós-natais. Método: Estudo de coorte retrospectiva envolvendo 74 gestantes com diagnóstico ecocardiográfico fetal de tumor cardíaco acompanhadas em dois serviços de referência no período de maio de 1991 a novembro de 2021. Foi realizada análise descritiva dos dados por meio de frequências absolutas (n) e relativas (%), mediana e intervalos interquartis. Para avaliar a associação entre as características ecocardiográficas e as manifestações clínicas com os resultados perinatais e pós-natais, foi aplicado o teste exato de Fisher. O cálculo da sobrevida global foi realizado pelo método de Kaplan-Meier e a comparação de curvas pelo teste de log-rank. O tempo de seguimento, calculado em meses, foi definido a partir da data de alta do hospital à data do status atual (vivo/censura ou óbito). O nível de significância considerado foi de 5% (p

ObjectiveTo assess a comparative analysis of the ROX index, Wood-Downes-Ferrés score (WDF), p-ROXI, and the SpO2/FiO2 ratio as predictors of high-flow nasal cannula (HFNC) failure in children hospitalized for bronchiolitis.MethodsData were extracted from the clinical trial "Comparison between HFNC and NIV in children with acute respiratory failure caused by bronchiolitis" conducted at a tertiary Brazilian hospital (Emergency Department and PICU). The inclusion criteria were children under 2 years of age admitted for bronchiolitis who developed mild to moderate respiratory distress and were eligible for HFNC therapy. Performance was determined by ROC and AUC metrics to define the best sensitivity and specificity for each variable. Children were evaluated at 0 h, 2 h, 6 h, 12 h, 24 h, 48 h, 72 h and 96 h after HFNC therapy initiation.ResultsA total of 126 patients were recruited for this analysis. The median age was 3 months. Ninety-one percent of the patients had an identified viral agent, with RSV being the most common (65%). Twenty-three percent (29/126) of patients experienced failed HFNC therapy and required mechanical ventilation. The best cutoff points at 12 hours were 4.5 for WDF (AUC = 0.83, 0.74-0.92), 8.8 for ROX (AUC = 0.7, 0.54-0.84), 1.45 for p-ROXI (AUC = 0.56, 0.38-0-74), and 269 for SpO2/FiO2 (AUC = 0.64, 0.48-0.74). The scores and indices were also correlated with the PICU and hospital LOS.ConclusionsThe ROX index and WDF were the most accurate scores for assessing HFNC failure considering 12-hour cutoff points.Trial registration numberU1111-1262-1740; RBR-104z966s.

Objective: Acute kidney injury (AKI) in the neonatal period is associated with worst outcomes as increased mortality and increased length of hospital stay. Very low birth weight (VLBW) newborns are at higher risk for developing several other conditions that are associated with worst outcomes. Understanding the risk factors for AKI may help to prevent this condition and improve neonatal care for this population. Methods: This retrospective cohort study included 155 very low birth weight newborns admitted between 2015 and 2017. The authors compared the newborns who developed neonatal AKI with the non-AKI group and analyzed the main risk factors for developing AKI in the population. The authors also performed an analysis of the main outcomes defined as the duration of mechanical ventilation, length of stay, and death. Results: From the cohort, a total of 61 (39.4%) patients had AKI. The main risk factors associated with Neonatal AKI were necrotizing enterocolitis (aOR 7.61 [1.69 – 34.37]; p = 0.008), neonatal sepsis (aOR 2.91 [1.17 – 7.24], p = 0.021), and hemodynamic instability (aOR 2.99 [1.35 – 6.64]; p = 0.007). Neonatal AKI was also associated with an increase in the duration of mechanical ventilation in 9.4 days (p = 0.026) and in an increase in mortality 4 times (p = 0.009), after adjusting for the other variables. Conclusion: The present results highlight the importance of minimizing sepsis and necrotizing enterocolitis, as well as the importance of identifying hemodynamic instability, to prevent AKI and diminish the burden of morbimortality in VLBW newborns.

Objective: Pediatric acute liver failure (PALF) is a heterogeneous, rare, and severe condition, which outcome is survival due to liver spontaneous recovery or death. The patients who do not recover may be allocated to liver transplantation, which is the standard treatment. This study aimed to build a prognostic model to support the clinical decision to indicate liver transplantation for patients with PALF in a Brazilian center. Methods: The authors retrospectively analyzed the clinical variables of 120 patients in the liver transplantation program of the 'Children's Institute of the University of São Paulo, Brazil. The authors conducted a univariate analysis of variables associated with survival in PALF. Logistic multivariate analysis was performed to find a prognostic model for the outcome of patients with pediatric acute liver failure. Results: Risk factors were analyzed using univariate analysis. Two prognostic models were built using multiple logistic regression, which resulted in 2 models: model 1(INR/ALT) and model 2 (INR/Total bilirubin). Both models showed a high sensitivity (97.9%/96.9%), good positive predictive value (89.5%/90.4%), and accuracy (88.4%/88.5%), respectively. The receiver operating characteristic was calculated for both models, and the area under the curve was 0.87 for model 1 and 0.88 for model 2. The Hosmer-Lemeshow test showed that model 1 was good. Conclusion: The authors built a prognostic model for PALF using INR and ALT that can contribute to the clinical decision to allocate patients to liver transplantation.

ABSTRACT Objective: To describe the incidence and to analyze risk factors associated with cholestasis in neonates with gastroschisis. Methods: This is a retrospective cohort study in a tertiary single center analyzing 181 newborns with gastroschisis between 2009 and 2020. The following risk factors associated with cholestasis were analyzed: gestational age, birth weight, type of gastroschisis, silo closure or immediate closure, days of parenteral nutrition, type of lipid emulsion, days of fasting, days to reach a full diet, days with central venous catheter, presence of infections, and outcomes. Results: Among the 176 patients evaluated, 41 (23.3%) evolved with cholestasis. In the univariate analysis, low birth weight (p=0.023), prematurity (p

RESUMO O objetivo do estudo foi verificar a aplicabilidade do Test of Infant Motor Performance (TIMP) em recém-nascidos (RN) cirúrgicos como ferramenta para avaliação do desempenho motor; e avaliar o benefício da fisioterapia. RN cirúrgicos, divididos em grupo sem fisioterapia motora (n=38) e com fisioterapia motora (n=38), foram avaliados pelo TIMP e reavaliados duas semanas depois. O grupo com fisioterapia realizou exercícios para estimulação sensório-motora uma vez ao dia, enquanto o grupo sem fisioterapia recebeu os cuidados habituais da Unidade de Terapia Intensiva Neonatal (UTIN). O diagnóstico cirúrgico predominante nos dois grupos foi de gastrosquise, seguido de hérnia diafragmática congênita. Na avaliação, não houve diferença no desempenho motor entre os grupos, classificados como “abaixo da média” para a idade, com escore-z=−1,28 (p=0,992). Na reavaliação, o grupo com fisioterapia apresentou melhor pontuação (p

ABSTRACT A male infant presented with progressive jaundice immediately after birth. Fecal acholia and choluria associated with extensive bullous skin lesions in his trunk, abdomen, and upper and lower limbs developed during phototherapy. Several diagnostic hypotheses were presented, including neonatal porphyria, hemochromatosis, Alagille syndrome, and neonatal lupus. A 24-hour urine sample for the dosage of urinary porphyrins was collected, showing high results (1823.6µg in 100mL). At 50 days of life, fluorescence spectroscopy using a Wood’s lamp revealed simultaneous bright red fluorescence of urine-stained diapers and sample blood. A definitive diagnosis of congenital erythropoietic porphyria was made following identification of a mutation of the uroporphyrinogen synthetases III gene on genetic testing. The patient was subsequently maintained in a low light environment since then, resulting in improvement of the lesions. Congenital erythropoietic porphyria is a disease of the group of porphyrias that presents shortly after birth with blistering occurring in regions exposed to the sun or other ultraviolet light. Atrophic scars, mutilated fingers, and bright red fluorescence of the urine and teeth may also be observed. There is no specific treatment, and prophylaxis comprising a total avoidance of sunlight is generally recommended. A high degree of suspicion is required for diagnosis. An early diagnosis can lead to less damage. Here, we present the case of a newborn with congenital erythropoietic porphyria diagnosed after presenting with bullous lesions secondary to phototherapy.

Objectives: To analyze late-onset sepsis and to describe the etiological agents in newborns with gastroschisis. Methods: A retrospective cohort, including newborns with gastroschisis whose admissions occurred in the period between January 2012 to December 2018 in a tertiary referral center. Maternal and newborn characteristics, surgical procedures and evolution in hospitalization were verified. A bivariate analysis was performed with patients with proven late-onset neonatal sepsis and according to the simple or complex gastroschisis category, the prevalent microorganisms in positive cultures were identified, statistical tests were carried out and the significance level adopted was p < 0,05. Results are presented in proportions, averages and standard deviation or medians. The level of significance adopted was p < 0.05. Results: 101 newborns were analyzed, 45 (44.5%) were confirmed late-onset sepsis. The median birth weight was 2285+498 grams, and the gestational age was 35.9 +1.74weeks. The incidence of complex gastroschisis was 17.8%, the hospitalization time was 48.2+29.67 days and mortality was 9.9%. The newborns were divided into 2 groups: Group 1: late-onset sepsis (44.6%), and Group 2: no late-onset sepsis. The presence of complex gastroschisis was a factor associated with infection (p < 0.009). Fasting time (p < 0.001), parenteral nutrition time (p < 0.001), time to achieve full diet (p < 0.001), and hospitalization stay (p < 0.001) were higher in group 2. Gram-positive were the most frequent (51.1%), followed by Gram-negative (20%), and fungi (4.4%). Conclusions: Newborns with gastroschisis have a higher risk of evolving with late-onset sepsis, despite this study did not calculate the risk of sepsis statistically, and the main germs detected by cultures were gram-positive bacteria, specifically Staphylococcus epidermidis.

RESUMO Objetivo: Avaliar o impacto no número de casos de oxigenação por membrana extracorpórea e as taxas de sobrevivência nos anos seguintes à pandemia de H1N1 de 2009. Métodos: Avaliaram-se dois períodos distintos de utilização de oxigenação por membrana extracorpórea como suporte para insuficiência respiratória em crianças, por meio da análise de conjuntos de dados da Extracorporeal Life Support Organization. Foram construídos modelos autorregressivos integrados de médias móveis para estimar os efeitos da pandemia. O ano de 2009 foi o ano de intervenção (epidemia de H1N1) em um modelo de séries temporais interrompidas. Os dados colhidos entre 2001 e 2010 foram considerados pré-intervenção e os obtidos entre 2010 e 2017 como pós-intervenção. Resultados: Em comparação com o período entre 2001 e 2010, o período entre 2010 e 2017 mostrou aumento das taxas de sobrevivência (p < 0,0001), com melhora significante da sobrevivência quando se realizou oxigenação por membrana extracorpórea nos casos de insuficiência aguda por pneumonia viral. Antes do ponto de nível de efeito (2009), o modelo autorregressivo integrado de médias móveis mostrou aumento de 23 casos de oxigenação por membrana extracorpórea ao ano. Em termos de sobrevivência, a curva mostra que não houve aumento significante das taxas de sobrevivência antes de 2009 (p = 0,41), porém o nível de efeito foi próximo à significância após 2 anos (p = 0,05), com aumento de 6% na sobrevivência. Em 4 anos, ocorreu aumento de 8% (p = 0,03) na sobrevivência, e, 6 anos após 2009, a sobrevivência mostrou aumento de até 10% (p = 0,026). Conclusão: Nos anos após 2009, ocorreu significante e progressivo aumento global das taxas de sobrevivência com oxigenação por membrana extracorpórea para todos os casos, principalmente em razão de melhoras tecnológicas e dos protocolos de tratamento para insuficiência respiratória aguda relacionada à pneumonia viral e a outras condições respiratórias.

Abstract Objective: The aim of this study was to describe the status of thyroid function in infants with severe intestinal dysfunction. Case description: A retrospective study was conducted in a tertiary neonatal intensive care center, including newborns and infants with severe intestinal dysfunction, hospitalized between 2015 and 2020. From the medical records, the following data were collected: gestational age, birth weight, underlying pathology that led to intestinal dysfunction, hospital stay, presence of thyroid dysfunction, age from the onset of thyroid dysfunction, initial and maximum dose of levothyroxine replacement, and levothyroxine administration route and outcome. Seven children (0.76% of 914 hospitalizations) developed severe intestinal insufficiency: vanishing gastroschisis (42.9%), Berdon syndrome (28.5%), apple peel (14.3%), and OIES syndrome (14.3%) – omphalocele, exstrophy of cloaca, imperforate anus, and spina bifida. The mean gestational age was 33.3±1.6 weeks, the mean birth weight was 2,113.9±370.9 g, the median hospitalization was 420 days, and mortality was 42.9%. Of these seven cases, four (57.1%) presented thyroid dysfunction, evaluated by blood hormone dosages and the dose of levothyroxine replacement ranged from 25 to 100 μg/day, administered by gastric or rectal route. Comments: This series of cases draws attention to thyroid dysfunction (hypothyroidism) in children with severe intestinal insufficiency receiving exclusive parenteral nutrition for a prolonged period, whose etiology is iodine deficiency, because, in Brazil, micronutrient solutions added to parenteral nutrition do not contain iodine.

Objective: Lactate is a marker of hypoperfusion in critically ill patients. Whether lactate is useful for identifying and stratifying neonates with a higher risk of adverse outcomes remains unknown. This study aimed to investigate the association between lactate and morbidity and mortality in neonates. Methods: A meta-analysis was performed to determine the association between blood lactate levels and outcomes in neonates. Ovid MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched from inception to 1 May 2021. A total of 49 observational studies and 14 data accuracy test studies were included. The risk of bias was assessed using the Newcastle-Ottawa Scale for observational studies and the QUADAS-2 tool for data accuracy test studies. The primary outcome was mortality, while the secondary outcomes included acute kidney injury, necessity for renal replacement therapy, neurological outcomes, respiratory morbidities, hemodynamic instability, and retinopathy of prematurity. Results: Of the 3184 articles screened, 63 studies fulfilled all eligibility criteria, comprising 46,069 neonates. Higher lactate levels are associated with mortality (standard mean difference, −1.09 [95% CI, −1.46 to −0.73]). Using the estimated sensitivity (0.769) and specificity (0.791) and assuming a prevalence of 15% for adverse outcomes (median of prevalence among studies) in a hypothetical cohort of 10,000 neonates, assessing the lactate level alone would miss 346 (3.46%) cases (false negative) and wrongly diagnose 1776 (17.76%) cases (false positive). Conclusions: Higher lactate levels are associated with a greater risk of mortality and morbidities in neonates. However, our results do not support the use of lactate as a screening test to identify adverse outcomes in newborns. Research efforts should focus on analyzing serial lactate measurements, rather than a single measurement.

Resumo Fundamento A pandemia da COVID-19 representa uma enorme carga para o sistema de saúde do mundo. Apesar de pacientes pediátricos terem sido relativamente poupados em comparação a adultos, estudos recentes mostraram um número crescente de pacientes críticos com Síndrome Inflamatória Multisistêmica Pediátrica (SIM-P) com disfunção cardiovascular importante. No entanto, pouco se conhece a respeito da relação entre anormalidades cardíacas e biomarcadores inflamatórios e de coagulação. Objetivos Investigar anormalidades ecocardiográficas em pacientes pediátricos com COVID-19 admitidos em um hospital terciário. Métodos Este foi um estudo longitudinal retrospectivo, baseado na revisão de prontuários médicos e ecocardiogramas de pacientes (0-19 anos) admitidos em um hospital terciário entre 30 de março e 30 de junho de 2020. Para a análise estatística, o nível de significância foi estabelecido em 5% (p+2,5). Anormalidades ecocardiográficas foram significativamente associadas com SIM-P, admissão na unidade de terapia intensiva pediátrica, suporte ventilatório/vasoativo, e morte ( p

Resumo Fundamento O período neonatal é marcado por muitas alterações importantes no sistema cardiovascular, principalmente na primeira semana de vida. Diferentemente da população adulta, estudos sobre dados de eletrocardiograma (ECG) no período neonatal são escassos. Este é o primeiro estudo a descrever alterações eletrocardiográficas em uma coorte de recém-nascidos com ecocardiogramas normais. Objetivos Analisar padrões eletrocardiográficos de uma população de recém-nascidos a termo, sem anomalias morfológicas ou funcionais cardíacas, e comparar os resultados com a literatura. Métodos Neste estudo observacional, ecocardiogramas e resultados de ECG de 94 neonatos divididos em três grupos etários (até 24 horas, entre 25 e 72 horas, e entre 73 e 168 horas de vida) foram avaliados e comparados com aqueles descritos por Davignon et al. Um valor de p < 0,05 foi considerado estatisticamente significativo. Resultados Diferenças significativas na direção da onda T foram detectadas nas derivações V1 (p= 0,04), V2 (p= 0,02), V3 (p= 0,008) e V4 (p= 0,005). Houve diferenças entre nossos resultados e a literatura atual na maioria dos parâmetros. Conclusão Recém-nascidos a termo com menos de 24 horas de vida apresentaram significativamente mais ondas T positivas que aqueles com mais horas de vida. Encontramos muitas diferenças nos parâmetros de ECG em comparação aos descritos por Davignon et al., particularmente nas amplitudes de P, Q, R, S, duração do QRS, R/S e R+S. Esses achados indicam a necessidade de mais estudos para uma interpretação definitiva do ECG em recém-nascidos.

Objective: To evaluate the orofacial characteristics of very low-birth-weight preterm infants through anthropometric facial measures, orofacial anteroposterior analysis and the relationship between the gum pads. Method: Orofacial examinations was performed in 154 infants, classified into two groups: Group A comprised 54 very low-birth-weight infants who were examined after clinical stabilization and before hospital discharge, and Group B comprised 100 full-term infants. Results: The average anthropometricmeasurements in millimetres for Group A and Group B were as follows: upper third:30.2 and 31.1; middle third: 24.2 and 25.9; lower third: 27.6 and 29.9; facial width: 64.8and 81.4. Regarding the orofacial anteroposterior analysis, the results showed that in99% of these infants, the mandible was in a retrognathic position relative to the maxilla.Group A and Group B had the following distributions of the relationship between thegum pads: overbite-overjet: 43% and 77%; overjet: 39% and 17%; open bite: 15% and3%; end-to-end: 2% and 1%; overbite: both 2%. Conclusion: The very low-birth-weight preterm infants showed the upper third with the highest values in the facialharmony analysis, followed by the lower third and the middle third; and exhibited themandible in a retrognathic position relative to the maxilla, and with overbite-overjet themost prevalent type of gum pad relationship. The study emphasizes the importance of orofacial examination during neonatal hospitalization and the investigation of birth weight and gestational age in a multidisciplinary therapeutic approach that includes orofacial neonatal evaluation and actions that promote oral health, besides foster follow-up studies.

Objective: Perform a systematic review and meta‐analysis to assess the effectiveness and complications caused by the use of the high‐flow nasal cannula in relation to the post‐extubation continuous positive airway pressure system in preterm newborns. Data Sources: The searches were performed from January 2013 to December 2018 in the PubMed and Embase databases, as well as a manual search on the internet. Data Synthesis: Two reviewers independently conducted the search, and a third reviewer resolved questions that arose. Ninety‐eight articles from the chosen sources were evaluated, and 66 were discarded because they did not meet the inclusion criteria (inadequate topic, age range, or design, in addition to the duplicates). Fifteen articles were read in full, and five more were discarded due to inadequacy to the topic or design. There were ten articles left for systematic review and four for meta‐analysis. The study showed non‐inferiority in terms of therapeutic failure of the high‐flow nasal cannula in relation to continuous positive airway pressure after extubation of preterm newborns. In the meta‐analysis, nasal trauma was significantly lower in patients submitted to the high‐flow nasal cannula compared to those using continuous positive airway pressure (p < 0.00001). Conclusion: The high‐flow nasal cannula is not inferior to continuous positive airway pressure for post‐extubation respiratory support in preterm newborns with a gestational age of 32 weeks or less and greater than 28 weeks, in addition to resulting in less nasal trauma. Resumo: Objetivo: Realizar revisão sistemática e metanálise para avaliar efetividade e complicações decorrentes do uso da cânula nasal de alto fluxo em relação ao sistema de pressão positiva contínua de vias aéreas no período pós‐extubação em recém‐nascidos prematuros. Fontes dos dados: As buscas foram feitas de janeiro de 2013 a dezembro de 2018 nas bases de dados PubMed, Embase e busca manual em arquivos da internet. Resumo dos dados: Dois revisores fizeram a busca de forma independente, um terceiro revisor ficou para dirimir dúvidas. Foram avaliados 98 artigos das fontes escolhidas, 66 descartados por não se enquadrar nos critérios de inclusão (tema, faixa etária ou desenho inadequados, além dos duplicados). Foram lidos 15 artigos na íntegra, foram descartados mais 5 por inadequação ao tema ou desenho. Restaram 10 artigos para revisão sistemática e 4 para metanálise. O estudo evidenciou não inferioridade em termos de falha terapêutica da cânula nasal de alto fluxo em relação ao sistema de pressão positiva contínua de vias aéreas na pós‐extubação de recém‐nascidos prematuros. Na metanálise, foi significativamente menor o trauma nasal nos pacientes em cânula nasal de alto fluxo em relação ao que usaram sistema de pressão positiva contínua de vias aéreas (p < 0,00001). Conclusão: A cânula nasal de alto fluxo não é inferior ao sistema de pressão positiva contínua de vias aéreas para o suporte respiratório pós‐extubação de recém‐nascidos prematuros com idade gestacional igual a ou menor do que 32 semanas e maior do que 28 semanas, além de provocar menos trauma nasal.

OBJECTIVES: To compare demographic/clinical/laboratory/treatments and outcomes among children and adolescents with laboratory-confirmed coronavirus disease 2019 (COVID-19). METHODS: This was a cross-sectional study that included patients diagnosed with pediatric COVID-19 (aged

Background: COVID-19 in children is usually mild or asymptomatic, but severe and fatal paediatric cases have been described. The pathology of COVID-19 in children is not known; the proposed pathogenesis for severe cases includes immune-mediated mechanisms or the direct effect of SARS-CoV-2 on tissues. We describe the autopsy findings in five cases of paediatric COVID-19 and provide mechanistic insight into the mechanisms involved in the pathogenesis of the disease. Methods: Children and adolescents who died with COVID-19 between March 18 and August 15, 2020 were autopsied with a minimally invasive method. Tissue samples from all vital organs were analysed by histology, electron microscopy (EM), reverse-transcription polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC). Findings: Five patients were included, one male and four female, aged 7 months to 15 years. Two patients had severe diseases before SARS-CoV-2 infection: adrenal carcinoma and Edwards syndrome. Three patients were previously healthy and had multisystem inflammatory syndrome in children (MIS-C) with distinct clinical presentations: myocarditis, colitis, and acute encephalopathy with status epilepticus. Autopsy findings varied amongst patients and included mild to severe COVID-19 pneumonia, pulmonary microthrombosis, cerebral oedema with reactive gliosis, myocarditis, intestinal inflammation, and haemophagocytosis. SARS-CoV-2 was detected in all patients in lungs, heart and kidneys by at least one method (RT-PCR, IHC or EM), and in endothelial cells from heart and brain in two patients with MIS-C (IHC). In addition, we show for the first time the presence of SARS-CoV-2 in the brain tissue of a child with MIS-C with acute encephalopathy, and in the intestinal tissue of a child with acute colitis. Interpretation: SARS-CoV-2 can infect several cell and tissue types in paediatric patients, and the target organ for the clinical manifestation varies amongst individuals. Two major patterns of severe COVID-19 were observed: a primarily pulmonary disease, with severe acute respiratory disease and diffuse alveolar damage, or a multisystem inflammatory syndrome with the involvement of several organs. The presence of SARS-CoV-2 in several organs, associated with cellular ultrastructural changes, reinforces the hypothesis that a direct effect of SARS-CoV-2 on tissues is involved in the pathogenesis of MIS-C.

ABSTRACT We report the clinical case of an infant with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with gastrointestinal signs and symptoms, predominantly vomiting. The patient also had colic, poor feeding, mild diarrhea and mild rhinorrhea without fever. The child had evidence of altered coagulation, increased interleukin 10, moderate dehydration and she was admitted to the pediatric intensive care unit. Simultaneously, the patient was diagnosed as Clostridioides difficile infection, which possibly may have facilitated the persistence of SARS-CoV-2 in feces, for more than 27 days, even after the nasopharyngeal test turned negative. This coinfection might exacerbate the gastrointestinal signs and symptoms and increased the possibility of fecal-oral transmission of SARS-CoV-2 and Clostridioides . The patient was breastfed and received complementary infant formula, hydrated with intravenous fluid, and was discharged without complications, 4 days after admission.

Coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), became a pandemic in March 2020, affecting millions of people worldwide. However, COVID-19 in pediatric patients represents 1-5% of all cases, and the risk for developing severe disease and critical illness is much lower in children with COVID-19 than in adults. Multisystem inflammatory syndrome in children (MIS-C), a possible complication of COVID-19, has been described as a hyperinflammatory condition with multiorgan involvement similar to that in Kawasaki disease or toxic shock syndrome in children with evidence of SARS-CoV-2 infection. This review presents an update on the diagnostic methods for COVID-19, including reverse-transcriptase polymerase chain reaction (RT-PCR) tests, serology tests, and imaging, and summarizes the current recommendations for the management of the disease. Particular emphasis is placed on respiratory support, which includes noninvasive ventilation and invasive mechanical ventilation strategies according to lung compliance and pattern of lung injury. Pharmacological treatment, including pathogen-targeted drugs and host-directed therapies, has been addressed. The diagnostic criteria and management of MIS-C are also summarized.

SARS-CoV-2 shares nearly 80% of its’ genomic sequence with SARS-CoV and MERS-CoV, both viruses known to cause respiratory symptoms and liver impairment. The emergence of pediatric cases of multisystem inflammatory syndrome related to the SARS-CoV-2 infection (PIM-TS) has raised concerns over the issue of hepatic damage and liver enzyme elevation in the critically ill pediatric population with COVID-19. Some retrospective cohorts and case series have shown various degrees of ALT/AST elevation in SARS-CoV-2 infections. A limited number of liver histopathological studies are available that show focal hepatic periportal necrosis. This liver damage was associated with higher levels of inflammatory markers, C-reactive protein (CRP), and pro-calcitonin. Proposed pathophysiological mechanisms include an uncontrolled exacerbated inflammatory response, drug-induced liver injury, direct viral infection and damage to cholangiocytes, hypoxic-ischemic lesions, and micro-thrombosis in the liver. Based on the physiopathological characteristics described, our group proposes a clinical protocol for the surveillance, evaluation, management, and follow-up of critically ill pediatric COVID-19 patients with liver damage.

OBJECTIVES: To assess the outcomes of pediatric patients with laboratory-confirmed coronavirus disease (COVID-19) with or without multisystem inflammatory syndrome in children (MIS-C). METHODS: This cross-sectional study included 471 samples collected from 371 patients (age50 mg/L (83% vs. 25%, p=0.008) and D-dimer levels >1000 ng/mL (100% vs. 40%, p=0.007) and the median D-dimer, troponin T, and ferritin levels (p

ABSTRACT Coronavirus disease 2019 (COVID-19) is a disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which has spread globally in pandemic proportions. Accumulative evidence suggests SARS-CoV-2 can be transmitted through the digestive system, the so-called fecal-oral route of transmission, and may induce several gastrointestinal manifestations. MEDLINE® and Embase databases were extensively searched for major clinical manifestations of gastrointestinal involvement in children and adolescents with COVID-19 reported in medical literature, and for nutritional therapy-related data. Findings and recommendations were pragmatically described to facilitate overall pediatric approach. A total of 196 studies addressing gastrointestinal or nutritional aspects associated with the global COVID-19 pandemic were found. Of these, only 17 focused specifically on pediatric patients with regard to aforementioned gastrointestinal or nutritional aspects. Most articles were descriptive and six addressed guidelines, established protocols, or expert opinions. Children and adolescents with gastrointestinal symptoms, such as nausea, vomiting and diarrhea, should be seriously suspected of COVID-19. Gastrointestinal signs and symptoms may occur in 3% to 79% of children, adolescents and adults with COVID-19, and are more common in severe cases. These include diarrhea (2% to 50%), anorexia (40% to 50%), vomiting (4% to 67%), nausea (1% to 30%), abdominal pain (2% to 6%) and gastrointestinal bleeding (4% to 14%). Patients with inflammatory bowel disease or chronic liver disease are not at greater risk of infection by SARS-CoV-2 relative to the general population. Nutritional support plays an important role in treatment of pediatric patients, particularly those with severe or critical forms of the disease. The digestive system may be a potential route of COVID-19 transmission. Further research is needed to determine whether the fecal-oral route may be involved in viral spread. Nutritional therapy is vital to prevent malnutrition and sarcopenia in severe cases.

This review aims to verify the main epidemiologic, clinical, laboratory-related, and therapeutic aspects of coronavirus disease 2019 (COVID-19) in critically ill pediatric patients. An extensive review of the medical literature on COVID-19 was performed, mainly focusing on the critical care of pediatric patients, considering expert opinions and recent reports related to this new disease. Experts from a large Brazilian public university analyzed all recently published material to produce a report aiming to standardize the care of critically ill children and adolescents. The report emphasizes on the clinical presentations of the disease and ventilatory support in pediatric patients with COVID-19. It establishes a flowchart to guide health practitioners on triaging critical cases. COVID-19 is essentially an unknown clinical condition for the majority of pediatric intensive care professionals. Guidelines developed by experts can help all practitioners standardize their attitudes and improve the treatment of COVID-19.

ABSTRACT Objective: To report the case of a child who developed acute respiratory distress syndrome (ARDS) from a pulmonary infection by adenovirus. Case description: A female patient aged 2 years and 6 months, weighting 10,295 grams developed fever, productive cough and vomiting, later on progressing to ARDS despite initial therapy in accordance with the institutional protocol for ARDS treatment. The child evolved to refractory hypoxemia and hypercapnia, requiring high parameters of mechanical pulmonary ventilation and use of vasoactive agents. In the treatment escalation, the patient received steroids, inhaled nitric oxide (iNO), was submitted to the prone position, started oscillatory high-frequency ventilation (HFOV) and extracorporeal membrane oxygenation (ECMO) was indicated due to severe refractory hypoxemia. During this time, the patient’s clinical response was favorable to HFOV, improving oxygenation index and hypercapnia, allowing the reduction of vasoactive medications and mechanical ventilation parameters, and then the indication of ECMO was suspended. The patient was discharged after 26 days of hospital stay without respiratory or neurological sequelae. Comments: Adenovirus infections occur mainly in infants and children under 5 years of age and represent 2 to 5% of respiratory diseases among pediatric patients. Although most children with adenovirus develop a mild upper respiratory tract disease, more severe cases can occur. ARDS is a serious pulmonary inflammatory process with alveolar damage and hypoxemic respiratory failure; Adenovirus pneumonia in children may manifest as severe pulmonary morbidity and respiratory failure that may require prolonged mechanical ventilation. Exclusive pulmonary recruitment and HFOV are advantageous therapeutic options.

RESUMO Objetivo Investigar o desempenho lexical e a habilidade de memória de curto prazo verbal em crianças prematuras em idade pré-escolar, e comparar os resultados com seus pares nascidos a termo. Método Participaram do estudo 40 pré-escolares com idade entre 4 e 5 anos e 11 meses divididos em dois grupos, sendo 20 nascidos prematuros e 20 nascidos a termo. Os grupos não diferiram quanto à idade, renda familiar e escolaridade materna. Foram utilizados testes de vocabulário expressivo e memória de curto prazo verbal. A análise estatística inferencial foi realizada por meio dos testes de Mann-Whitney e exato de Fisher. Resultados O desempenho dos grupos não diferiu na tarefa de vocabulário, mas o grupo de prematuros apresentou desempenho inferior ao de seus pares na tarefa de repetição de não palavras. Conclusão Nesta amostra, o desempenho dos pré-escolares que nasceram prematuros foi estatisticamente inferior ao daqueles nascidos a termo apenas na tarefa de repetição de não palavras. Assim, o nascimento prematuro esteve associado a desempenho no vocabulário expressivo compatível com o esperado para a idade, porém com prejuízos na memória de curto prazo verbal.

ABSTRACT Objective To understand the use of tools, protocols and comfort measures related to sedation/analgesia, and to screen the occurrence of delirium in pediatric intensive care units. Methods A survey with 14 questions was distributed by e-mail to Brazilian critical care pediatricians. Eight questions addressed physician and hospital demographics, and six inquired practices to assess sedation, analgesia, and delirium in pediatric intensive care units. Results Of 373 questionnaires sent, 61 were answered (16.3%). The majority of physicians were practicing in the Southeast region (57.2%). Of these, 46.5% worked at public hospitals, 28.6% of which under direct state administration. Of respondents, 57.1% used formal protocols for sedation and analgesia, and the Ramsay scale was the most frequently employed (52.5%). Delirium screening scores were not used by 48.2% of physicians. The Cornell Assessment of Pediatric Delirium was the score most often used (23.2%). The majority (85.7%) of physicians did not practice daily sedation interruption, and only 23.2% used non-pharmacological measures for patient comfort frequently, with varied participation of parents in the process. Conclusion This study highlights the heterogeneity of practices for assessment of sedation/analgesia and lack of detection of delirium among critical care pediatricians in Brazil.

ABSTRACT Objective: To measure the level of satisfaction regarding the usability of a neonatal health information system and identify if demographic factors can influence the usability of a health information system. Methods: A cross-sectional, exploratory study was carried out with a convenience sample of 50 users of the Brazilian Neonatal Research Network. The instrument chosen for the usability evaluation was the System Usability Scale between February and March 2017. The statistical analysis of the collected variables was carried out in order to describe the sample, to quantify the level of satisfaction of the users and to identify the variables associated with the level of satisfaction. Results: The female gender represented 75% of the sample. The mean age was 52.8 years; 58% had a doctoral degree, average time of graduation was 17 years, with area of practice in medicine (neonatology), with intermediate knowledge in computer science (74%) and mean system use time of 52 months. Regarding usability, 94% rated the system as “good”, “excellent” or “better than imaginable”. The usability of the system was not associated with age, gender, education, profession, area of practice, knowledge in computer science and time of system use. Conclusion: The level of satisfaction of the computerized health system user was considered good. No demographic factors were associated with the satisfaction of the users.

RESUMO Objetivo: Relatar o caso de um lactente que necessitou de intubação traqueal no setor de emergência pediátrica por conta de laringite aguda grave e que, após a extubação traqueal programada, fez uso, com sucesso, da cânula nasal de alto fluxo, a qual, possivelmente, evitou a falha da extubação traqueal. Descrição do caso: Paciente masculino, 8 meses de idade, admitido no pronto atendimento de pediatria com desconforto respiratório agudo por causa de obstrução alta de vias aéreas secundária à laringite aguda grave. Foi imediatamente intubado e encaminhado para a unidade de terapia intensiva (UTI) pediátrica. Apresentou falha de extubação em função de edema importante de laringe evidenciado por broncoscopia, o que contraindicou a extubação. Na segunda tentativa de extubação, o paciente apresentou desconforto respiratório, melhorando após uso da cânula nasal de alto fluxo, com redução da frequência cardíaca e respiratória, possibilitando a extubação com sucesso. Comentários: O uso da cânula nasal de alto fluxo foi eficaz e apresentou boa resposta nesse paciente com laringite aguda, sugerindo ser um possível adjuvante para o tratamento, evitando-se a piora do quadro respiratório e da necessidade de reintubação.

RESUMO Relatamos o caso de um uma criança de 2 anos de idade que sobreviveu após um episódio agudo de hemorragia intracraniana espontânea grave com sinais clínicos e radiológicos de hipertensão intracraniana e herniação transtentorial. O paciente foi para cirurgia de urgência para drenagem do hematoma, sendo inserido um cateter para monitorar a pressão intracraniana. Na análise da tomografia de crânio inicial, antes da drenagem do hematoma, constatou-se um cisto cerebral contralateral ao hematoma que, segundo análise do neurocirurgião e do neuroradiologista, possivelmente evitou um desfecho pior, visto que o cisto serviu de acomodação para o cérebro após a hemorragia maciça. Após investigação, constatou-se tratar de um caso de hemofilia tipo A sem diagnóstico prévio. O paciente foi tratado em terapia intensiva com controle da pressão intracraniana, reposição de fator VIII e obteve alta sem sequelas neurológicas evidentes.

RESUMOA síndrome do desconforto respiratório agudo é uma patologia de início agudo, marcada por hipoxemia e infiltrados na radiografia de tórax, acometendo tanto adultos quanto crianças de todas as faixas etárias. Ela é causa importante de insuficiência respiratória em unidades de terapia intensiva pediátrica associada a significativa morbidade e mortalidade. Apesar disso, até recentemente, as definições e os critérios diagnósticos para síndrome do desconforto respiratório agudo centravam-se na população adulta. No presente artigo, revisamos a evolução da definição da síndrome do desconforto respiratório agudo ao longo de quase cinco décadas, com foco especial na nova definição pediátrica. Discutimos ainda recomendações relativas à aplicação de estratégias de ventilação mecânica no tratamento da síndrome do desconforto respiratório agudo em crianças, assim como o uso de terapias adjuvantes.

RESUMO Objetivo: Relatar um caso raro de síndrome posterior do tronco cerebral em um lactente após um episódio hipóxico-isquêmico devido a sepse grave, e o uso da ventilação assistida ajustada neuralmente no auxílio diagnóstico e no desmame da ventilação mecânica. Descrição do caso: Lactente masculino de 2 meses de idade, previamente hígido, apresentou sepse grave que evoluiu para síndrome posterior do tronco encefálico, entidade que pode ocorrer após lesão hipóxico-isquêmica em neonatos e lactentes e que apresenta imagens de ressonância magnética muito particulares. Devido à lesão neurológica, permaneceu em ventilação mecânica. Optou-se por iniciar ventilação assistida ajustada neuralmente para verificar a patência da condução do nervo frênico ao diafragma e auxiliar no desmame da ventilação mecânica. Comentários: A síndrome posterior do tronco cerebral é uma entidade rara que deve ser considerada em lactentes após evento hipóxico-isquêmico.

OBJECTIVE: To analyze the nutritional status of pediatric patients after orthotopic liver transplantation and the relationship with short-term clinical outcome. METHOD: Anthropometric evaluations of 60 children and adolescents after orthotopic liver transplantation, during the first 24 hours in a tertiary pediatric intensive care unit. Nutritional status was determined from the Z score for the following indices: weight/age height/age or length/age, weight/height or weight/length, body mass index/age, arm circumference/age and triceps skinfold/age. The severity of liver disease was evaluated using one of the two models which was adequated to the patients' age: 1. Pediatric End-stage Liver Disease, 2. Model for End-Stage Liver Disease. RESULTS: We found 50.0% undernutrition by height/age; 27.3% by weight/age; 11.1% by weight/height or weight/ length; 10.0% by body mass index/age; 61.6% by arm circumference/age and 51.0% by triceps skinfold/age. There was no correlation between nutritional status and Pediatric End-stage Liver Disease or mortality. We found a negative correlation between arm circumference/age and length of hospitalization. CONCLUSION: Children with chronic liver diseases experience a significant degree of undernutrition, which makes nutritional support an important aspect of therapy. Despite the difficulties in assessment, anthropometric evaluation of the upper limbs is useful to evaluate nutritional status of children before or after liver transplantation.

OBJETIVO: Descrever os principais aspectos epidemiológicos, clínicos, diagnósticos e do tratamento de crianças com pancreatite aguda. FONTES DOS DADOS: Realizada revisão sistemática das bases de dados MEDLINE e SciELO nos últimos 5 anos sobre pancreatite aguda em crianças, bem como consultadas referências relevantes dos textos obtidos. SÍNTESE DOS DADOS: Os casos de pancreatite aguda em crianças recebem crescente atenção nos últimos anos, sendo verificado um aumento na incidência da doença em diversos estudos. As principais etiologias em crianças envolvem doença biliar, pancreatite secundária a medicamentos, pancreatite hereditária recorrente e trauma, sendo até 30% dos casos sem etiologia definida. O diagnóstico baseia-se na combinação de aspectos clínicos, laboratoriais com elevação das enzimas acinares e testes radiológicos. Tratamento de suporte inicial, com reposição volêmica adequada e correção dos distúrbios metabólicos, além de terapêutica nutricional específica, são os pontos fundamentais no manejo dos quadros agudos. Complicações a longo prazo são incomuns, e as taxas de mortalidade, inferiores às da população adulta. CONCLUSÃO: O diagnóstico precoce e o manejo apropriado podem contribuir para a melhor evolução da criança com pancreatite e prevenir as complicações imediatas e tardias relacionadas à doença. Mais estudos são necessários para melhor elucidar aspectos relacionados ao diagnóstico clínico e radiológico da pancreatite em crianças, bem como aspectos da terapêutica nutricional nessa faixa etária.

OBJETIVOS: Conhecer as práticas referentes ao uso de ventilação por pressão positiva intermitente nasal (VPPIN) em unidades terciárias de atendimento neonatal do Nordeste brasileiro. MÉTODOS: Estudo observacional seccional tipo inquérito, realizado entre março de 2009 e janeiro de 2010 em todas as instituições de atendimento neonatal de nível terciário localizadas no Nordeste brasileiro, cadastradas no Conselho Nacional dos Estabelecimentos de Saúde do Ministério de Saúde. Realizado por meio de levantamento, utilizando questionários sobre o uso de VPPIN, enviados aos responsáveis das unidades de cuidados intensivos neonatais de cada instituição. A análise estatística foi realizada pelo software Epi-Info versão 6.04, com dupla entrada de dados. As variáveis foram comparadas pelo teste do qui-quadrado, sendo considerado nível de significância de 5%. RESULTADOS: Estão cadastradas no Conselho Nacional dos Estabelecimentos de Saúde 93 unidades terciárias neonatais no Nordeste brasileiro. Os questionários foram respondidos por 87% delas. A maior parte classificou-se como de natureza privada (30,7%) ou pública estadual (29,4%). O número de instituições que se utilizam da VPPIN correspondeu a 98,7% do total. Grande parte das unidades (92,8 %) declarou utilizar aparelhos de ventilação pulmonar mecânica, adaptados para aplicação de VPPIN, e pronga binasal curta como interface (94,2%). O protocolo para aplicação de VPPIN existia em apenas 17,3% das unidades. A média dos valores de pressão positiva inspiratória adotados foi de 20,0 cmH2O (desvio padrão = 4,47) e de pressão expiratória final positiva foi de 5,0 cmH2O (desvio padrão = 0,84). CONCLUSÃO: A ventilação por pressão positiva intermitente nasal representa um suporte utilizado pelas unidades neonatais no Nordeste brasileiro, embora se observe pouca uniformização quanto às indicações e parâmetros adotados entre as instituições.

This study compared the balance between effort (E) and reward (R) among physicians and nurses working in pediatric (PED) and neonatal (NEO) Intensive Care Units. This descriptive cross-sectional study was carried out with 37 physicians and 20 nurses. The Effort-Reward Imbalance Questionnaire was used. Statistically significant differences were not found among physicians (p>0.05) or nurses from PED and NEO in relation to E and R (p>0.05). No statistically significant differences were found between physicians and nurses in PED in the several studied variables. Comparison between the professionals working in NEO revealed that physicians presented more over-commitment than nurses (p=0.01). The organizational setting of NEO proved to be more demanding for physicians, exacting a greater commitment to their work, while demands presented in both units seemed to be the same for nurses.El objetivo del estudio fue comparar el equilibrio entre esfuerzo (E) y recompensa (R) entre médicos de unidades de terapia intensiva pediátrica (PED) y neonatal (NEO) y entre enfermeros de las mismas unidades.

OBJETIVOS: Listar 1) as definições e características epidemiológicas de acidentes vasculares encefálicos (AVE) em crianças; 2) os principais fatores de risco para a ocorrência de AVE em pediatria e neonatologia; 3) as principais características fisiopatológicas para a ocorrência de lesão cerebral no AVE; 4) as manifestações clínicas e o diagnóstico por imagem; e 5) as recomendações atualizadas para as medidas de suporte, tratamento e profilaxia dos AVE em pediatria. FONTES DOS DADOS: Realizou-se revisão da literatura nas bases de dados PubMed, EMBASE e SciELO utilizando-se como palavras-chave stroke, pediatrics e neonatology, além da utilização de referências bibliográficas importantes dos textos escolhidos. SÍNTESE DOS DADOS: A ocorrência de AVE em pediatria é incomum, com a incidência variando entre duas e oito por 100.000 crianças abaixo de 14 anos, tendo a maioria como denominador comum a ocorrência de doenças de base como cardiopatias congênitas, anemia falciforme e malformações vasculares. Não há padronização nas recomendações de tratamento para o AVE em crianças, embora as medidas fundamentais incluam monitoração, tratamento de suporte e anticoagulação em casos selecionados. O prognóstico depende da extensão de área cerebral acometida e da doença de base, mas as taxas de recorrência são altas na maioria dos casos. CONCLUSÕES: O diagnóstico precoce dos AVE em pediatria é fundamental, e é importante que os pediatras estejam atentos à falta de especificidade dos sintomas para evitar sequelas e melhorar a qualidade de vida dos pacientes acometidos.OBJECTIVES: To summarize 1) the definitions and epidemiological features of stroke in children; 2) the main risk factors that can lead to stroke in pediatrics and neonatology; 3) the main pathophysiological features involved in the genesis of brain injury in stroke; 4) the clinical manifestations and imaging diagnosis; and 5) the latest recommendations concerning the support measures, treatment, and prophylaxis of stroke in children. SOURCES: A review of the literature published in PubMed, EMBASE, and SciELO databases using the search terms stroke, pediatrics, and neonatology was performed, including relevant references from the chosen texts. SUMMARY OF THE FINDINGS: Stroke in children are rare conditions, with incidence rates among two and eight per 100,000 children up to 14 years, and most cases show an underlying disease such as heart diseases, prothrombotic conditions, sickle-cell disease, and vascular malformations. There are no specific guidelines currently in place for the treatment of stroke in children, although central elements include support treatment, monitoring, and anticoagulation as secondary prevention in certain cases. Prognosis depends on the extent of brain damage and the underlying disease but recurrence rates are high in most cases. CONCLUSIONS: Early diagnosis of stroke in children is very important and pediatricians should be aware of the lack of specificity of the symptoms to avoid late sequelae and improve life quality.

OBJETIVOS: Revisão de literatura sobre estresse ocupacional e síndrome de burnout em médicos e enfermeiros que trabalham em unidade de terapia intensiva pediátrica e neonatal. MÉTODOS: Os artigos foram identificados a partir das bases de dados MedLine, LILACS e SciElo, usando as palavras-chave estresse, burnout, médicos, enfermagem, unidade de terapia intensiva, unidade de cuidados intensivos pediátricos e unidades de cuidados intensivos neonatais. O período pesquisado foi de 1990 a 2007. RESULTADOS: Médicos e enfermeiros que trabalham em unidade de terapia intensiva pediátrica e neonatal são candidatos a apresentarem estresse, alterações psicológicas e síndrome de Burnout. Pesquisas sobre o tema identificaram alterações importantes que acometem médicos e enfermeiros intensivistas: sobrecarga de trabalho, burnout, desejo de abandonar o trabalho e níveis elevados de cortisol entre outros fatores. CONCLUSÕES: Os profissionais que trabalham em unidade de terapia intensiva pediátrica e neonatal , pela especificidade do seu trabalho, estão expostos ao risco do estresse ocupacional e, conseqüentemente ao Burnout. Estes dados sugerem a necessidade de serem feitas pesquisas, com o objetivo de desenvolver medidas preventivas e modelos de intervenção.OBJECTIVES: Bibliographic review on occupational stress and burnout presence in physicians and nurses that work in pediatric and neonatal intensive care units. METHODS: The articles were selected from the MedLine, LILACS and SciElo data base using the key words: stress, burnout, physicians, nursing, intensive care unit, pediatric intensive care unit and neonatal intensive care unit. The studied period ranged from 1990 to 2007. RESULTS: Health professionals who work in pediatric and neonatal intensive care units are strong candidates for developing stress, psychological alterations and burnout syndrome. Researches on this subject identified important alterations suffered by these physicians and nurses, such as: work overload, burnout, desires of giving up their jobs, high levels of cortisol, among other alterations. CONCLUSIONS: Professionals, who work in pediatric and neonatal intensive care units, due to the specificity of their job, are liable to develop occupational stress, and consequently burnout. These results suggest the need for further research with the objective of developing preventive measures and intervention models.
