Content validation of a questionnaire to assess the knowledge of pediatricians, family, and community physicians on obesity / Validação do conteúdo de um questionário para a avaliação do conhecimento de pediatras e médicos da família e comunidade sobre obesidade

ABSTRACT Objective: The aim of this study was to validate the content of a questionnaire in order to assess the attitudes and practices in childcare consultations, knowledge on overweight and obesity, their risk factors, and barriers in addressing the issue by pediatricians and family physicians. Methods: The Delphi technique was used, with the objective of reaching a consensus on a certain subject, through experts' opinions. The content validity index (CVI) of each item, axis, and questionnaire was calculated. The inter-rater reliability was calculated using an agreement coefficient suitable for the answer distribution such as Gwet's AC2 with ordinal weight. Results: A total of 63 experts were invited to assess and give their opinion on the questionnaire. In all, 52 accepted the invitation and analyzed the instrument. After two rounds, the questionnaire reached the proper CVI for the study and was considered complete, with its final version having 40 questions, a final index of 95%, and an inter-rate reliability of 0.905. Conclusions: This instrument, developed to assess attitudes and practices, knowledge, and barriers found in addressing the obesity by primary care physicians, obtained a CVI greater than 0.8 and an excellent agreement coefficient of the 52 judges. Therefore, its content can be considered validated.

Knowledge of gynecologists in the public health system care of women victims of violence

SUMMARY OBJECTIVE: This study aimed to evaluate the knowledge of the obstetricians and gynecologists in the care of women victims of violence in the public health system and the existence of institutional mechanisms to support them. METHODS: A cross-sectional and observational study was conducted with an electronic questionnaire by physicians who provided care in the obstetrics and gynecology emergency unit of the public health system. This study aimed to identify the care for victims of violence who received the institutional mechanisms of support, the difficulties encountered in determining the appropriate care, and estimates of the prevalence of violence against women. RESULTS: Notably, 92 physicians responded to the questionnaire. Of these, 85% had already provided care in one or more cases of violence, and 60% believed that <20% of the women received adequate care in these cases, mainly due to the short-time frame of the consultation, lack of team preparation, and lack of institutional resources. A total of 61% of the participants believed that they were not prepared to provide adequate care in those cases. CONCLUSIONS: Most of the physicians interviewed, although reported to have sufficient knowledge to adequately treat victims of violence, did not provide such care due to lack of institutional support.

Factors associated with multidrug-resistant bacteria in healthcare-associated infections: a pediatric intensive care unit case-control study

ABSTRACT Objective To investigate the prevalence of factors related to healthcare-associated infections, caused by multidrug-resistant bacteria, in a pediatric intensive care unit. Methods A retrospective case-control study conducted from January 1, 2007 to December 31, 2018, in São Paulo (SP), Brazil. The study was carried out at the pediatric intensive care unit of a high-complexity, tertiary care general hospital. The study included patients aged 1 month to 19 years, admitted to the pediatric intensive care unit, diagnosed as healthcare-associated infections. Results There was significant evidence of infection by multidrug-resistant bacteria associated with immunosuppressed patients (p<0.001), in whom the likelihood of multidrug-resistant bacteria infection was estimated to be nine-fold higher than among non-immunosuppressed patients (OR 8.97; 95%CI 2.69-29.94). In the analysis of multiple logistic regression model, we observed that immunosuppressed patients had an 8.5-fold higher chance of multidrug-resistant bacteria infection when compared to non-immunosuppressed patients (OR 8.48; 95%CI 2.54-28.35; p=0.001). There is evidence of association between the Case Group and presence of Gram-positive (p=0.007), coagulase-negative Staphylococcus (p<0.001), and Gram-negative (p=0.041) microorganisms. Conclusion The immunocompromised-state variable is a factor related to healthcare-associated infections caused by multidrug-resistant bacteria, and the Case Group presented higher proportions of Gram-positive microorganisms and coagulase-negative Staphylococcus.

Epidemiology and treatment of sepsis at a public pediatric emergency department

ABSTRACT Objective To describe the clinical characteristics and treatment of children with sepsis, severe sepsis, and septic shock at a pediatric emergency department of a public hospital. Methods A retrospective, observational study. The medical records of patients included in the hospital Pediatric Sepsis Protocol and patients with discharge ICD-10 A41.9 (sepsis, unspecified), R57 (shock) and A39 (meningococcal meningitis) were evaluated. Results A total of 399 patients were included. The prevalence of sepsis, severe sepsis, and septic shock at the emergency room were 0.41%, 0.14% and 0.014%, respectively. The median age was 21.5 months for sepsis, 12 months for severe sepsis, and 20.5 months for septic shock. Sepsis, severe sepsis, and septic shock were more often associated with respiratory diseases. The Respiratory Syncytial Virus was the most common agent. The median time to antibiotic and fluid administration was 3 hours in patients with sepsis and severe sepsis. In patients with septic shock, the median times to administer antibiotics, fluid and vasoactive drugs were 2 hours, 2.5 hours and 6 hours, respectively. The median length of hospital stay for patients with sepsis, severe sepsis and septic shock were 3 days, 4 days and 1 day, respectively. The overall mortality was 2%. Conclusion Sepsis had a low prevalence. Early diagnosis and recognition are a challenge for the emergency care pediatrician, the first place of admission.

Fim de vida em unidades de terapia intensiva pediátrica / End of life in pediatric intensive care units / Final de la vida en unidades de cuidados intensivos pediátricos

Resumo Este artigo analisa as condutas de fim de vida em unidades de terapia intensiva pediátrica brasileiras. Trata-se de estudo observacional, retrospectivo, multicêntrico, incluindo crianças que faleceram entre janeiro e dezembro de 2017. Durante o período ocorreram 149 óbitos, dos quais 54 foram selecionados. Constatou-se que 83,3% dos pacientes apresentavam alguma doença de base, com choque séptico como principal causa de óbito (38,9%). Limitações de suporte de vida foram descritas em 46,3% dos prontuários, e ordem de não reanimar em 37%; porém, 74,1% dos pacientes deixaram de ser reanimados. A prática de não reanimar pacientes com prognóstico reservado tem se disseminado, e aponta-se para melhores cuidados nas últimas 48 horas de vida. No entanto, ainda se verifica uso excessivo de procedimentos invasivos, ventilação mecânica e drogas vasoativas nas horas derradeiras.

Abstract This article analyzes end-of-life procedures in Brazilian pediatric intensive care units. This is an observational, retrospective, multicenter study, including children who died between January and December 2017. During the period, 149 deaths occurred, of which 54 were selected. We found that 83.3% of patients had a base illness, being septic shock the main cause of death (38.9%). Life support limitations were described in 46.3% of the medical records, and a do-not-resuscitate order for 37% of the patients; however, 74.1% were not resuscitated. The practice of not resuscitating patients with a reserved prognosis and better care in the last 48 hours of life have become more common in recent years. However, there are still excessive use of invasive procedures, mechanical ventilation, and vasoactive drugs in the last hours of life.

Resumen El objetivo de este artículo es analizar las conductas al final de la vida en unidades de cuidados intensivos pediátricos brasileños. Este es un estudio observacional, retrospectivo, multicéntrico, que incluye a niños que murieron entre enero y diciembre de 2017. Durante el período, ocurrieron 149 muertes, de las cuales 54 fueron seleccionadas. Se encontró que el 83,3% de los pacientes tenían alguna enfermedad de base, con shock séptico como la principal causa de muerte (38,9%). Las limitaciones de soporte vital se describieron en el 46,3% de los registros médicos, y el orden de no resucitar en el 37%; sin embargo, no se resucitaron el 74,1% de los pacientes. La práctica de no resucitar a pacientes con mal pronóstico es cada vez más frecuente, y ya se pueden observar mejoras en la atención en las últimas 48 horas de vida. Sin embargo, todavía hay un uso excesivo de procedimientos invasivos, ventilación mecánica y drogas vasoactivas en las últimas horas.

Length of stay in pediatric intensive care unit: prediction model / Tempo de permanência em unidade de terapia intensiva pediátrica: modelo de predição

ABSTRACT Objective To propose a predictive model for the length of stay risk among children admitted to a pediatric intensive care unit based on demographic and clinical characteristics upon admission. Methods This was a retrospective cohort study conducted at a private and general hospital located in the municipality of Sao Paulo, Brazil. We used internal validation procedures and obtained an area under ROC curve for the to build of the predictive model. Results The mean hospital stay was 2 days. Predictive model resulted in a score that enabled the segmentation of hospital stay from 1 to 2 days, 3 to 4 days, and more than 4 days. The accuracy model from 3 to 4 days was 0.71 and model greater than 4 days was 0.69. The accuracy found for 3 to 4 days (65%) and greater than 4 days (66%) of hospital stay showed a chance of correctness, which was considering modest. Conclusion: Our results showed that low accuracy found in the predictive model did not enable the model to be exclusively adopted for decision-making or discharge planning. Predictive models of length of stay risk that consider variables of patients obtained only upon admission are limit, because they do not consider other characteristics present during hospitalization such as possible complications and adverse events, features that could impact negatively the accuracy of the proposed model.

RESUMO Objetivo Propor um modelo de predição de risco de permanência das crianças na unidade de terapia intensiva pediátrica, considerando-se as características demográficas e clínicas na admissão. Métodos Coorte retrospectiva realizada a partir da análise de 1.815 admissões na terapia intensiva pediátrica, em um hospital privado e geral, do município de São Paulo (SP). Foram utilizados procedimentos de validação interna e obtenção da área sob a curva ROC na construção do modelo preditor. Resultados A mediana do tempo de permanência foi de 2 dias. O modelo preditor produziu um escore que permitiu a segmentação do tempo de permanência de 1 a 2 dias, de 3 a 4 dias e maior que 4 dias. A acurácia do modelo de 3 a 4 dias foi de 0,71 e do modelo maior que 4 dias de 0,69. As acurácias encontradas para 3 a 4 dias e maior que 4 dias de permanência mostraram possibilidade de acerto, considerada modesta, de 65% e 66%, respectivamente. Conclusão A partir dos resultados encontrados, é possível verificar que a baixa acurácia encontrada no modelo preditor não permite que ele seja exclusivamente adotado para a tomada de decisão ou planejamento para a alta. Modelos de predição de risco do tempo de permanência que consideram variáveis do paciente obtidas somente durante a admissão têm limitações intrínsecas, já que não consideram outras características presentes durante a internação, como possíveis complicações e eventos adversos, e podem impactar negativamente na acurácia do modelo proposto.

Vomiting in newborns as a result of a duodenal membrane: two case reports / Episódios de vômitos em recém-nascidos como consequência de membrana duodenal: relatos de dois casos

ABSTRACT Vomiting episodes in newborns are extremely common and often attributed to gastroesophageal reflux. The symptoms of vomiting, however, may be caused by other complications. In this report, we present two cases of a 1-month-old male and a 2-month-old female, both presenting vomiting episodes that led to malnutrition. Some pediatricians often attribute the diagnosis of gastroesophageal reflux to newborns that are vomiting; however, there is a portion of the population that has other causes that lead to similar symptoms. The pediatrician should be alert to the clinical signs of weight loss, dehydration and malnutrition to investigate other causes of vomiting.

RESUMO Episódios de vômito em recém-nascidos são extremamente comuns e frequentemente atribuídos a refluxo gastresofágico. Os sintomas de vômito, no entanto, podem ser causados por outras complicações. Neste relato, apresentamos dois casos: um lactente masculino, com 1 mês de idade, e um feminino, com 2 meses, ambos apresentando episódios de vômitos que levaram à desnutrição. Alguns pediatras costumam atribuir o diagnóstico de refluxo gastresofágico a recém-nascidos que estão vomitando; mas parcela da população tem outras causas que levam a sintomas semelhantes. O pediatra deve estar atento aos sinais clínicos de perda de peso, desidratação e desnutrição, para investigar outras causas de vômitos.

Fatores de risco para infecções da corrente sanguínea relacionadas a cateter em unidades de terapia intensiva pediátrica / Risk factors for vascular catheter-related bloodstream infections in pediatric intensive care units

RESUMO Objetivo: Determinar os fatores de risco para contrair infecções da corrente sanguínea associadas a cateter de acesso central em unidades de terapia intensiva pediátrica, e investigar a incidência e a etiologia dessas infecções nas unidades de terapia intensiva pediátrica com diferentes perfis. Métodos: Este foi um estudo prospectivo de coorte, conduzido em três hospitais. Um deles é um grande hospital público metropolitano, com duas unidades de terapia intensiva pediátrica que contabilizam 19 leitos; o segundo é um hospital regional com oito leitos em unidade de terapia intensiva pediátrica; e o terceiro é um hospital privado com 15 leitos de terapia intensiva pediátrica. Incluíram-se pacientes com idades entre 1 mês e 18 anos, que utilizaram cateter de acesso venoso central por pelo menos 24 horas. Registramos a evolução diária dos pacientes. Colheram-se dados gerais sobre o paciente e sobre o cateter, utilizados como variáveis. Todos os dados foram analisados com utilização do pacote estatístico Statistical Package for Social Science (SPSS), versão 13.0, para comparação de pacientes com infecção da corrente sanguínea associada a cateter com ou sem fatores de risco. Resultados: Durante o período do estudo admitiram-se às unidades de terapia intensiva 728 pacientes; deles, 170 tiveram cateter de acesso venoso central instalado por, no mínimo, 24 horas. A mediana de idade foi de 32 meses, e 97 (57%) dos pacientes eram do sexo masculino. A taxa de incidência de infecções da corrente sanguínea relacionadas a cateter foi de 3,9/1.000 cateteres venosos centrais-dias. A incidência variou entre os hospitais, sendo de 1,6 a 6,6. A taxa geral de mortalidade foi de 11,1%, e as taxas de mortalidade com e sem infecções da corrente sanguínea relacionadas a cateter foram, respectivamente, de 12,9% e 10,7%. Na análise multivariada, os fatores de risco para ocorrência de infecções da corrente sanguínea relacionadas a cateter foram maior tempo de uso do cateter venoso central (OR: 1,07; IC95% 1,00 - 1,14; p = 0,019) e o uso de mais de um cateter venoso central de uma vez (OR: 2,59; IC95% 1,17 - 5,73; p = 0,048). Conclusão: Maior duração do uso de cateter venoso central e mais de um cateter venoso central de uma vez foram os principais fatores de risco para infecções da corrente sanguínea associadas a cateter em unidades de terapia intensiva pediátrica.

ABSTRACT Objectives: To determine the risk factors for acquiring central line-associated blood stream infections (CLABSI) in pediatric intensive care units and to investigate the incidence and etiology of CLABSI in pediatric intensive care units with different profiles. Methods: The study was a prospective cohort study in three hospitals. One of the hospitals is a large metropolitan public hospital with two pediatric intensive care units and a total of nineteen pediatric intensive care unit beds, another is a regional hospital with eight pediatric intensive care unit beds, and the third is a private hospital with fifteen beds. Patients between the ages of 1 month old and 18 years old who used a central venous catheter for over 24 hours were included. We recorded patients' daily progress. General patient and catheter-related data were collected and used as variables. All the data were analyzed using Statistical Package for Social Science (SPSS), version 13.0, to compare patients with CLABSI with or without risk factors. Results: A total of 728 patients were admitted to the pediatric intensive care units, and 170 had a central line in place for at least 24 hours. The median age was 32 months, and 97 (57%) of the patients were males. The CLABSI incidence rate was 3.9/1000 central venous catheter-days. The incidence among hospitals varied from 1.6 to 6.6. The overall mortality rate was 11.1%, and the CLABSI and non-CLABSI mortality rates were 12.9% and 10.7%, respectively. In multivariate analysis, independent risk factors for CLABSI were a longer duration of central venous catheter use (OR: 1.07; 95%CI 1.00 - 1.14; p = 0.019) and the use of more than one central venous catheter at once (OR: 2.59; 95%CI 1.17 - 5.73; p = 0.048). Conclusion: A longer duration of central venous catheter use and the use of more than one central venous catheter at once were the main risk factors for CLABSI in pediatric intensive care units.

Utilização de escore e dosagem de lactato no líquor para diagnóstico diferencial entre meningite bacteriana e meningite asséptica / Use of score and cerebrospinal fluid lactate dosage in differential diagnosis of bacterial and aseptic meningitis

RESUMO Objetivo: Avaliar o Escore para Meningite Bacteriana (EMB) isolado e associado ao valor do lactato no líquor para diferenciar meningite bacteriana (MB) e meningite asséptica (MA). Métodos: Foram selecionadas crianças com meningite atendidas em hospital terciário privado entre janeiro de 2011 e dezembro de 2014. Os dados foram obtidos na admissão. Utilizou-se o EMB com: coloração de Gram no líquor (2 pontos); neutrófilos no líquor ≥1.000 células/mm3 (1 ponto); proteína no líquor ≥80 mg/dL (1 ponto); neutrófilos no sangue periférico ≥10.000 células/mm3 (1 ponto); e convulsão durante/antes da chegada (1 ponto). Analisou-se também o lactato no líquor (elevado: ≥30 mg/dL). Avaliaram-se sensibilidade, especificidade e valor preditivo negativo de diversos valores de corte do EMB e do EMB associado ao lactato elevado para prever MB. Resultados: Dos 439 pacientes elegíveis, 94 não tinham todos os dados necessários para o escore, sendo 345 pacientes selecionados: 7 no grupo de MB e 338 no de MA. Como preditivos de MB, o EMB ≥1 mostrou sensibilidade de 100% (intervalo de confiança de 95% - IC95% 47,3-100), especificidade de 64,2% (58,8-100) e valor preditivo negativo de 100% (97,5-100), enquanto o EMB ≥2 ou EMB ≥1 associado a lactato liquórico ≥30 mg/dL mostrou sensibilidade de 100% (47,3-100), especificidade de 98,5% (96,6-99,5) e valor preditivo negativo de 100% (98,3-100). Conclusões: O EMB com 2 pontos associado à dosagem de lactato no líquor manteve a sensibilidade e o valor preditivo negativo, ao passo que aumentou a especificidade para identificar meningites bacterianas em relação à utilização do EMB com 1 ponto.

ABSTRACT Objective: To evaluate Bacterial Meningitis Score (BMS) on its own and in association with Cerebrospinal Fluid (CSF) lactate dosage in order to distinguish bacterial from aseptic meningitis. Methods: Children diagnosed with meningitis at a tertiary hospital between January/2011 and December/2014 were selected. All data were obtained upon admission. BMS was applied and included: CSF Gram staining (2 points); CSF neutrophil count ≥1,000 cells/mm3 (1 point); CSF protein ≥80 mg/dL (1 point); peripheral blood neutrophil count ≥10,000 cells/mm3 (1 point) and seizures upon/before arrival (1 point). Cutoff value for CSF lactate was ≥30 mg/dL. Sensitivity, specificity and negative predictive value of several BMS cutoffs and BMS associated with high CSF lactate were evaluated for prediction of bacterial meningitis. Results: Among 439 eligible patients, 94 did not have all data available to complete the score, and 345 patients were included: 7 in bacterial meningitis group and 338 in aseptic meningitis group. As predictive factors of bacterial meningitis, BMS ≥1 had 100% sensitivity (95%CI 47.3-100), 64.2% specificity (58.8-100) and 100% negative predictive value (97.5-100); BMS ≥2 or BMS ≥1 associated with high CSF lactate also showed 100% sensitivity (47.3-100); but 98.5% specificity (96.6-99.5) and 100% negative predictive value (98.3-100). Conclusions: 2 point BMS in association with CSF lactate dosage had the same sensitivity and negative predictive value, with increased specificity for diagnosis of bacterial meningitis when compared with 1-point BMS.

Comparison of enterovirus detection in cerebrospinal fluid with Bacterial Meningitis Score in children / Comparação da pesquisa de enterovírus no liquor com Escore de Meningite Bacteriana em crianças

ABSTRACT Objective To measure the role of enterovirus detection in cerebrospinal fluid compared with the Bacterial Meningitis Score in children with meningitis. Methods A retrospective cohort based on analysis of medical records of pediatric patients diagnosed as meningitis, seen at a private and tertiary hospital in São Paulo, Brazil, between 2011 and 2014. Excluded were patients with critical illness, purpura, ventricular shunt or recent neurosurgery, immunosuppression, concomitant bacterial infection requiring parenteral antibiotic therapy, and those who received antibiotics 72 hours before lumbar puncture. Results The study included 503 patients. Sixty-four patients were excluded and 94 were not submitted to all tests for analysis. Of the remaining 345 patients, 7 were in the Bacterial Meningitis Group and 338 in the Aseptic Meningitis Group. There was no statistical difference between the groups. In the Bacterial Meningitis Score analysis, of the 338 patients with possible aseptic meningitis (negative cultures), 121 of them had one or more points in the Bacterial Meningitis Score, with sensitivity of 100%, specificity of 64.2%, and negative predictive value of 100%. Of the 121 patients with positive Bacterial Meningitis Score, 71% (86 patients) had a positive enterovirus detection in cerebrospinal fluid. Conclusion Enterovirus detection in cerebrospinal fluid was effective to differentiate bacterial from viral meningitis. When the test was analyzed together with the Bacterial Meningitis Score, specificity was higher when compared to Bacterial Meningitis Score alone.

RESUMO Objetivo Avaliar o papel da pesquisa de enterovírus no líquido cefalorraquidiano em comparação com o Escore de Meningite Bacteriana em crianças com meningite. Métodos Coorte retrospectiva, realizada pela análise de prontuários, incluindo pacientes pediátricos, com diagnóstico de meningite e atendidos em um hospital privado e terciário, localizado em São Paulo, entre 2011 e 2014. Foram excluídos os pacientes com doença crítica, púrpura, derivação ventricular ou neurocirurgia recente, imunossupressão, outra infecção bacteriana concomitante que necessitasse de antibioticoterapia parenteral e aqueles que receberam antibiótico 72 horas antes da punção lombar. Resultados Foram incluídos no estudo 503 pacientes. Destes, 64 foram excluídos e 94 não realizaram todos os exames para análise. Dos 345 pacientes restantes, 7 ficaram no Grupo de Meningite Bacteriana e 338 no Grupo de Meningite Asséptica. Não houve diferença estatística entre os grupos. Na análise do Escore de Meningite Bacteriana, dos 338 pacientes com possível meningite asséptica (culturas negativas), 121 deles tiveram um ou mais pontos para o Escore de Meningite Bacteriana, com valor de sensibilidade de 100%, especificidade de 64,2% e valor preditivo negativo de 100%. Dos 121 pacientes com Escore de Meningite Bacteriana positivo, 71% (86 pacientes) tiveram a pesquisa de enterovírus positiva no líquido cefalorraquidiano. Conclusão A pesquisa de enterovírus no líquido cefalorraquidiano mostrou-se eficaz em diferenciar a meningite bacteriana da viral. Analisada junto com o Escore de Meningite Bacteriana, a especificidade foi maior em comparação ao Escore de Meningite Bacteriana isolado.

Lymphocyte count as a sign of immunoparalysis and its correlation with nutritional status in pediatric intensive care patients with sepsis: A pilot study

OBJECTIVES: Developing malnutrition during hospitalization is well recognized worldwide, and children are at a relatively higher risk for malnutrition than adults. Malnutrition can lead to immune dysfunction, which is associated with a higher mortality rate due to sepsis, the most frequent cause of death in pediatric intensive care units (PICUs). The aim of this study was to investigate whether malnourished patients are more likely to have relative or absolute lymphopenia and, consequently, worse prognoses. METHODS: We enrolled 14 consecutive patients with sepsis whose legal representatives provided written informed consent. Patients were classified as normal or malnourished based on anthropometric measurements. As an additional evaluation of nutritional status, serum albumin and zinc were measured on the 1st and 7th days of hospitalization. Lymphocyte count was also measured on the 1st and 7th days. Clinicaltrials.gov: NCT02698683. RESULTS: Malnutrition prevalence rates were 33.3% and 42.8% based on weight and height, respectively. Laboratory analyses revealed a reduction of serum albumin in 100% of patients and reduction of zinc in 93.3% of patients. A total of 35% of patients had fewer than 500 lymphocytes/mm3 on their first day in the PICU. Lymphocyte counts and zinc concentrations significantly increased during hospitalization. CONCLUSIONS: Nutritional evaluations, including anthropometric measurements, were not correlated with lymphocyte counts. Lymphocyte counts concomitantly increased with zinc levels, suggesting that micronutrient supplementation benefits patients with sepsis.

Risk factors for post-extubation stridor in children: the role of orotracheal cannula / Fatores de risco para estridor pós-extubação em crianças: o papel da cânula orotraqueal

Objective To determine the risk factors associated with stridor, with special attention to the role of the cuffed orotracheal cannula. Methods Prospective analysis of all the intubated patients submitted to mechanical ventilator support from January 2008 to April 2011. The relevant factors for stridor collected were age, weight, size and type of airway tube, diagnosis, and duration of mechanical ventilation. The effects of variables on stridor were evaluated using uni- and multivariate logistic regression models. Results A total of 136 patients were included. Mean age was 1.4 year (3 days to 17 years). The mean duration of mechanical ventilation was 73.5 hours. Fifty-six patients (41.2%) presented with stridor after extubation. The total reintubation rate was 19.6% and 12.5 in patients with and without stridor, respectively. The duration of mechanical ventilation (>72 hours) was associated with a greater risk for stridor (odds ratio of 8.60; 95% confidence interval of 2.98-24.82; p<0.001). The presence of the cuffed orotracheal cannula was not associated with stridor (odds ratio of 98; 95% confidence interval of 0.46-2.06; p=0.953). Conclusion The main risk factor for stridor after extubation in our population was duration of mechanical ventilation. The presence of the cuffed orotracheal cannula was not associated with increased risk for stridor, reinforcing the use of the cuffed orotracheal cannula in children with respiratory distress. .

Objetivo Determinar os fatores de risco associados ao estridor, com especial atenção para o papel da cânula orotraqueal. Métodos Análise prospectiva de todos os pacientes entubados submetidos à ventilação mecânica no período de janeiro de 2008 a abril de 2011. Os fatores relevantes para estridor coletados foram idade, peso, tamanho e tipo da cânula orotraqueal, diagnóstico, e duração da ventilação mecânica. Os efeitos das variáveis sobre estridor foram avaliados utilizando modelos de regressão logística uni e multivariada. Resultados Foram incluídos 136 pacientes. A média de idade foi 1,4 ano (3 dias a 17 anos). O tempo médio de ventilação mecânica foi 73,5 horas. Apresentaram estridor após extubação 56 pacientes (41,2%). A taxa de reintubação foi de 19,6% e 12,5% em pacientes com ou sem estridor, respectivamente. A duração da ventilação mecânica (>72 horas) foi associada a um maior risco de estridor (odds ratio de 8,60; intervalo de confiança de 95% de 2,98-24,82; p<0,001). A presença da cânula orotraqueal não foi associada ao estridor (odds ratio de 0,98; intervalo de confiança de 95% de 0,46- 2,06; p=0,953). Conclusão O principal fator de risco para estridor após extubação em nossa população foi o tempo de ventilação mecânica. A presença da cânula orotraqueal não foi associada a maior risco de estridor, reforçando o uso de cânulas com balonete em crianças com dificuldade respiratória. .

Meningite por Haemophilus influenzae tipo f / Meningitis due to Haemophilus influenzae type f

Com o declínio da taxa de infecções causadas pelo Haemophilus influenzae tipo b após a ampla introdução da vacina, sorotipos não-b devem ser considerados agentes patogênicos potenciais em crianças menores de 5 anos com doença invasiva. Relatamos um caso de meningite por Haemophilus influenzae tipo f em um lactente imunocompetente de 1 ano. O agente foi identificado em líquido cefalorraquidiano e hemocultura. A sorotipagem foi realizada por testes com soros policlonais e confirmada por reação em cadeia de polimerase. Todas as cepas de Haemophilus influenzae associadas à doença invasiva deveriam ser sorotipadas e notificadas, a fim de possibilitar uma análise adequada das mudanças e tendências na distribuição de sorotipos desta doença.

With the decline in the rate of infections caused by Haemophilus influenzae serotype b since the widespread vaccination, non-b serotypes should be considered as potential pathogenic agents in children with invasive disease younger than 5 years old. We report the case of an immunocompetent 1-year-old boy with Haemophilus influenzae type f meningitis. The agent was identified in cerebrospinal fluid and blood cultures. Serotyping was performed by tests using polyclonal sera and confirmed by polymerase chain reaction. All Haemophilus influenzae isolates associated with invasive disease should be serotyped and notified as a way to evaluate the changes and trends in serotype distribution of this disease.

What types of unintentional injuries kill our children? Do infants die of the same types of injuries? A systematic review

The objective of this study was to review mortality from external causes (accidental injury) in children and adolescents in systematically selected journals. This was a systematic review of the literature on mortality from accidental injury in children and adolescents. We searched the Pubrvled, Latin-American and Caribbean Health Sciences and Excerpta Medica databases for articles published between July of 2001 and June of 2011. National data from official agencies, retrieved by manual searches, were also reviewed. We reviewed 15 journal articles, the 2011 edition of a National Safety Council publication and 2010 statistical data from the Brazilian National Ministry of Health Mortality Database. Most published data were related to high-income countries. Mortality from accidental injury was highest among children less than 1 year of age. Accidental threats to breathing (non-drowning threats) constituted the leading cause of death among this age group in the published articles. Across the pediatric age group in the surveyed studies, traffic accidents were the leading cause of death, followed by accidental drowning and submersion. Traffic accidents constitute the leading external cause of accidental death among children in the countries understudy. However, infants were vulnerable to external causes, particularly to accidental non-drowning threats to breathing, and this age group had the highest mortality rates for external causes. Actions to reduce such events are suggested. Further studies investigating the occurrence of accidental deaths in low-income countries are needed to improve the understanding of these preventable events.

The epidemiological profile of Pediatric Intensive Care Center at Hospital Israelita Albert Einstein / O perfil epidemiológico do Centro de Terapia Intensiva Pediátrico do Hospital Israelita Albert Einstein

Objective: This study outlined the epidemiological profiles of patients who were admitted to the Pediatric Intensive Care Center at Albert Einstein Israelite Hospital during 2009. Methods: Data were retrospectively collected for all patients admitted to the PICC during 2009. A total of 433 medical charts were reviewed, and these data were extracted using the DATAMARTS System and analyzed using the statistical software package STATA, version 11.0. Results: There were no statistically significant differences in regards to patient gender, and the predominant age group consisted of patients between the ages of 1 to 4 years. The average occupancy rate was 69.3% per year, and there was a greater number of admissions during April, August, and October. The average length of stay at the hospital ranged from 9.7 to 19.1 days. Respiratory diseases were the main cause for admission to the Pediatric Intensive Care Center, and the mortality rate of the patients admitted was 1.85%. Conclusions: Respiratory diseases were the most common ailment among patients admitted to the Pediatric Intensive Care Center, and the highest mortality rates were associated with neoplastic diseases.

Objetivo: Traçar o perfil epidemiológico de pacientes admitidos no Centro de Terapia Intensiva Pediátrico do Hospital Israelita Albert Einstein no período de 1 ano. Métodos: Os dados foram coletados retrospectivamente de todos pacientes admitidos no Centro de Terapia Intensiva Pediátrico durante o ano de 2009. A extração dos dados contidos nos 433 prontuários revisados foi realizada do sistema DATAMARTS e analisada com o programa estatístico STATA, versão 11. Resultados: Não houve diferença significativa para gênero, e a faixa etária predominante foi de 1 a 4 anos. A média de ocupação foi de 69,3% ao ano com maior fluxo nos meses de abril, agosto e outubro. A média de permanência variou de 9,7 a 19,1 dias. As doenças respiratórias foram responsáveis pelo maior número de pacientes no Centro de Terapia Intensiva Pediátrico e a taxa de mortalidade foi de 1,85%. Conclusões: As doenças respiratórias foram as mais frequentes e a maior taxa de mortalidade esteve associada a doenças neoplásicas.

Meningoencephalitis associated with Mycoplasma pneumoniae / Meningoencefalite associada ao Mycoplasma pneumoniae

We report a case of a child with meningoencephalitis of atypical etiology. The patient developed the disease after an infection in the upper airways with unfavorable evolution. The clinical recovery was only possible after the administration of adequate antibiotic therapy for the etiological agent. This case report describes a child with meningoencephalitis of atypical etiology. The patient developed the disease after an infection in the superior airways with negative evolution. The clinical recovery was possible only after the introduction of adequate antibiotic therapy for the etiological agent.

Síndrome do desconforto respiratório agudo causada por Mycoplasma pneumoniae em uma criança: o papel da metilprednisolona e claritromicina / Acute respiratory distress syndrome caused by Mycoplasma pneumoniae in a child: the role of methylprednisolone and clarythromycin

Mycoplasma pneumoniae was recognized as an important agent of pneumonia in pediatric population. In rare situations, severe pulmonary injury can develop. The use of corticoids in these cases remains controversial. A case of a girl with acute respiratory distress syndrome and bilateral pleural effusion secondary to pneumonia due to Mycoplasma pneumoniae is described, with good recovery after appropriate use of methylprednisolone and clarythromicyn.
