ABSTRACT

Introducción: Las sibilancias recurrentes en lactantes y preescolares son motivo frecuente de consulta en pediatría. Objetivo: Caracterizar a niños con sibilancia recurrente desde los puntos de vista clínico y epidemiológico. Métodos: Se realizó una investigación observacional, longitudinal y prospectiva de 140 niños con sibilancia recurrente, atendidos en el Servicio de Respiratorio del Hospital Infantil Docente Sur Dr. Antonio María Béguez César de Santiago de Cuba, desde de enero de 2016 hasta diciembre de 2018. Resultados: Predominaron el sexo masculino (57,1 %), los pacientes de procedencia urbana (62,1 %) y el área de salud 28 de septiembre como la de mayor incidencia (42,7 %). El promedio de edad fue de 1 año y 5 meses, aproximadamente. Los niños incluidos en el intervalo de 6 a 11 meses y 29 días fueron los más afectados (28,6 %). Entre los municipios, Guamá aportó el mayor número de casos (33,9 %). No existió asociación estadística entre el índice predictivo de asma y el sexo; sin embargo, resultó mayor entre los varones (19,3 %). Conclusiones: Las características clínicas y epidemiológicas de los pacientes con sibilancia recurrente de esta casuística no difieren del contexto epidemiológico mundial, siendo una entidad de observación frecuente en los servicios de pediatría.

ABSTRACT

Abstract Objectives: to determine the prevalence and factors associated with recurrent wheezing in the first year of life among premature newborns from Neonatal Intensive Care Units, in the city of Montes Claros, northern Minas Gerais. Methods: cross-sectional study, with data collection from medical records of a follow-up clinic, interviews with mothers and, eventually, search in hospital records. Bivariate analyzes were carried out between sociodemographic and clinical characteristics and recurrent wheezing. Variables associated up to the level of 20% were analyzed by binary logistic regression, and associations defined by the Odds Ratio and respective 95% confidence intervals. Only variables associated with a 5% significance level were maintained in the final model of logistic regression. Results: among 277 infants studied, about one fifth (21.3%) were extremely low birth weight preterm and more than half (60.7%) had birth weight below 1500 grams. The prevalence of recurrent wheezing was 14.4% (CI95% = 10.3-18.4). Mechanical ventilation (OR = 2.12; CI95% = 1.09-4.76; p = 0.030) and oxygen therapy time ≥ 15 days (OR = 2.49; CI95%= 1.12-5.00; p = 0.010) were the risk factors for the event. Conclusions: there is a high prevalence of recurrent wheezing in the evaluated group and the associated variables reiterate the risk of prolonged oxygen therapy and mechanical ventilation for premature newborns.


Resumo Objetivos: determinar a prevalência e fatores associados à sibilância recorrente no primeiro ano de vida entre recém-nascidos prematuros egressos de Unidades de Terapia Intensiva Neonatais, na cidade de Montes Claros, norte de Minas Gerais. Métodos: estudo transversal, com coleta de dados em prontuários de ambulatório de seguimento, entrevistas com mães e, eventualmente, consultas aos prontuários hospitalares. Foram realizadas análises bivariadas entre as características sociodemográficas e clínicas e a sibilância recorrente. As variáveis associadas ao desfecho até um nível de significância de p ≤20% foram analisadas por regressão logística binária e as associações definidas pelas Odds Ratios e respectivos intervalos de confiança de 95%. Somente variáveis associadas a um nível de significância de 5% foram mantidas no modelo final de regressão logística. Resultados: entre 277 crianças estudadas, cerca de um quinto (21,3%) eram prematuros de extremo baixo peso e mais da metade (60,7%) tinha peso de nascimento abaixo de 1500 gramas. A prevalência de sibilância recorrente foi de 14,4% (IC95%=10,3-18,4). Ventilação mecânica (OR=2,12; IC95%= 1,09-4,76; p=0,030) e tempo de oxigenioterapia ≥15 dias (OR=2,49; IC95%=1,12-5,00; p=0,010) foram os fatores de risco para o evento. Conclusão: existe uma elevada prevalência de sibilância recorrente no grupo avaliado e as variáveis associadas reiteram o risco do uso prolongado de oxigenioterapia e da ventilação mecânica para recém-nascidos prematuros.

ABSTRACT

INTRODUCTION. Airway abnormalities are rare but potentially fatal. Stridor is a res-piratory noise with greater predominance in the inspiratory phase. OBJECTIVE. To evaluate the etiology of stridor, determine its comorbidities and mortality. MATERIALS AND METHODS. Retrospective cross-sectional study. Population of 110 and sample of 33 data from the Medical Records of neonatal or infant patients who presented stri-dor at the Carlos Andrade Marín Specialties Hospital of Quito-Ecuador, from january 2009 to december 2020. RESULTS. The 51,51% (17; 33) of cases were men. The age of the first consultation for stridor was within the first month in 18,00% (6; 33) and 40,00% (13; 33) at 3 months. The most frequent congenital laryngeal patholo-gy was: laryngomalacia 81,82% (27; 33), followed by subglottic stenosis 9,09% (3; 33), bilateral chordal paralysis 6,06% (2; 33) and tracheal stenosis 3,03% (1; 33). The 51,51% (17; 33) presented comorbidities of causes: neurological, pulmonary and genetic among the main ones. Mortality was 18,20% (6; 33) related to the severity of comorbidities, except one secondary to tracheal stenosis. CONCLUSION. Laryn-gomalacia and subglottic stenosis were the predominant pathologies with congenital stridor. The comorbidities that occurred were neurological, pulmonary, genetic and caused mortality within 90 days after diagnosis.

ABSTRACT

Abstract Introduction Foreign body aspiration (FBA) is a potentially fatal paediatric emergency. Our objective was to highlight the importance of a multidisciplinary approach to difficult/doubtful diagnosis. Case report 34-month-old girl referred for urgent rigid bronchoscopy after suspected metallic blade ingestion (found chewing on it). She had a previous recurrent history of wheezing. The physical examination revealed face/lip wounds, traces of powder on her teeth but no breathing difficulty. The plain X-Ray revealed radiopaque images of the upper pulmonary field and gastric chamber. In the absence of FBA clinical signs but considering a previous history of bronchial hyperresponsiveness, a direct digital radiographic study was performed. There were no images compatible with foreign bodies: the results were interpreted as artefacts and no bronchoscopy was performed. Conclusions A careful pre-anaesthetic evaluation, a high level of suspicion and excellent multidisciplinary communication led to the recognition of false radiologic findings. A conservative approach was followed and invasive procedures in a remote location, with high anaesthetic risk for the paediatric population were avoided.


Resumen Introducción La aspiración de cuerpo extraño (ACE) es una emergencia pediátrica potencialmente fatal. La intención del presente artículo es resaltar la importancia de un abordaje multidisciplinario en caso de un diagnóstico difícil/dudoso. Reporte de caso Se trata de una paciente de 4 meses de edad remitida para broncoscopia rígida de urgencia, luego de la sospecha de ingestión de una hojilla metálica (se encontró a la bebé mordiéndola). La paciente tenía antecedentes de sibilancia. Al examen físico se encontraron heridas en la cara y los labios, rastros de polvo en los dientes, pero no había dificultad respiratoria. El examen de rayos-x mostraba imágenes radio opacas en el cuadrante superior derecho del pulmón y en la cámara gástrica. En virtud de la ausencia de signos clínicos de ACE en una paciente con antecedentes de hiperresponsividad bronquial, se realizó un estudio radiográfico digital. No hubo imágenes compatibles con cuerpos extraños: los resultados se interpretaron como artefactos y no se realizó la broncoscopia. Conclusiones Un cuidadoso examen pre-anestesia, el alto grado de sospecha y una excelente comunicación multidisciplinaria, permitieron el reconocimiento de hallazgos radiológicos falsos. Se siguió un abordaje conservador, evitando así procedimientos invasivos en lugares remotos con alto grado de riesgo para la población pediátrica.

ABSTRACT

Objetivo del estudio: evaluar si la puntuación de Mallampati modificada (MMS) puede predecir la presencia y la gravedad del síndrome de apnea obstructiva del sueño (AOS) en un grupo de pacientes que roncaban y presentaban apnea en los hospitales universitarios de Al-Azhar, El Cairo, Egipto y el Hospital Almoosa, Alhasa, Arabia Saudita. Métodos: Se realizó un estudio retrospectivo de pacientes que roncaban y presentaron apnea remitidos a un laboratorio del sueño para el diagnóstico de AOS mediante polisomnograma completo durante la noche desde enero de 2017 a noviembre de 2020. Se utilizó el índice de apnea-hipopnea (IAH) para categorizar la gravedad apnea del sueño. Se registraron edad, sexo, SMM, índice de masa corporal (IMC), comorbilidades, sueño y parámetros de laboratorio. Además, se registraron exámenes completos de Otorrinolaringología, Neurología y Medicina Interna. Resultados: El estudio se realizó en 350 pacientes que cumplían los criterios de inclusión con una edad media de 51,3 ± 14,3 años con un rango de 14 a 81 años. Más de la mitad de ellos (58,6%) eran hombres, el IMC medio fue de 35,1 ± 8,8 kg / m2 y el MMS medio fue de 4,7 ± 1,6 con aproximadamente el 65% de los pacientes agrupados en clases III y IV. Se diagnosticó AOS (IAH> 5) en 278 (79,4%) pacientes. Significativamente, la AOS se detectó más entre los hombres, aquellos con mayor edad, IMC, MMS y aquellos con diabetes mellitus tipo 2 (DM2). Una evaluación adicional mostró una correlación positiva significativa entre el IMC y el MMS con la gravedad de la AOS (ρ = 0,23, P <0,001 y ρ = 0,36, P <0,001) respectivamente. Conclusión: MMS es una herramienta útil para predecir la presencia y la gravedad de la AOS en pacientes que roncan. El IMC y el sexo masculino son predictores independientes


Aim of the study: To assess if the modified Mallampati score (MMS) can predict the presence and the severity of obstructive sleep apnea syndrome (OSA) in a group of patients who had snoring and witnessed apnea from Al -Azhar university hospitals, Cairo, Egypt, and Almoosa Hospital, Alhasa, Saudi Arabia. Methods: A retrospective study was done for patients who had snoring and witnessed apnea referred to a sleep lab for the diagnosis of OSA by overnight full polysomnogram from January 2017 to November 2020. Apnea-hypopnea index (AHI) was used to categorize the severity of sleep apnea. Age, sex, MMS, body mass index (BMI), comorbidities, sleep and laboratory parameters were recorded. Also, full Otorhinolaryngological, Neurological and Internal medicine examinations were recorded. Results: The study was carried out on 350 patients fulfilling the inclusion criteria with a mean age 51.3 ± 14.3 years ranging from 14 to 81 years. More than half of them (58.6%) were males, the mean BMI was 35.1 ± 8.8 kg/m2 and the mean MMS was 4.7 ± 1.6 with about 65% of patients grouped in classes III and IV. OSA (AHI>5) was diagnosed in 278 (79.4%) patients. Significantly, OSA was more detected among males, those with increased age, BMI, MMS, and those with type 2 diabetes mellitus (T2DM). Further evaluation showed a significant positive correlation between both BMI and MMS with the severity of OSA (ρ =0.23, P<0.001 and ρ =0.36, P<0.001) respectively. Conclusion: MMS is a useful tool to predict the presence as well as the severity of OSA in snoring patients. BMI and male gender are independent predictors

ABSTRACT

ABSTRACT Objective: To determine the prevalence of recurrent wheezing (RW) in preterm infants who received prophylaxis against severe infection with respiratory syncytial virus (RSV) and to identify genetic susceptibility (atopy or asthma) and risk factors for RW. Methods: This was a cross-sectional study involving preterm infants who received prophylaxis with palivizumab at a referral center in Brazil during the first two years of age. A structured questionnaire was administered in a face-to-face interview with parents or legal guardians. Results: The study included 410 preterm infants (median age = 9 months [0-24 months]). In the sample as a whole, 111 children (27.1%; [95% CI, 22.9-31.5]) had RW. The univariate analysis between the groups with and without RW showed no differences regarding the following variables: sex, ethnicity, maternal level of education, gestational age, birth weight, breastfeeding, number of children in the household, day care center attendance, pets in the household, and smoking caregiver. The prevalence of RW was twice as high among children with bronchopulmonary dysplasia (adjusted OR = 2.08; 95% CI, 1.11-3.89; p = 0.022) and almost five times as high among those with a personal/family history of atopy (adjusted OR = 4.96; 95% CI, 2.62-9.39; p < 0.001) as among those without these conditions. Conclusions: Preterm infants who received prophylaxis with palivizumab but have a personal/family history of atopy or bronchopulmonary dysplasia are more likely to have RW than do those without these conditions.


RESUMO Objetivo: Determinar a prevalência de sibilância recorrente (SR) em crianças pré-termo que receberam profilaxia contra infecção grave pelo vírus sincicial respiratório (VSR) e identificar susceptibilidade genética (atopia ou asma) e fatores de risco para SR. Métodos: Estudo transversal envolvendo crianças pré-termo que receberam profilaxia com palivizumabe em um centro de referência no Brasil durante os primeiros dois anos de vida. Um questionário estruturado foi aplicado em entrevista presencial com os pais ou responsáveis. Resultados: O estudo incluiu 410 crianças pré-termo (mediana de idade = 9 meses [0-24 meses]). Na amostra total, 111 crianças (27,1%; IC95%: 22,9-31,5) apresentavam SR. A análise univariada entre os grupos com e sem SR não mostrou diferenças em relação às seguintes variáveis: sexo, etnia, escolaridade materna, idade gestacional, peso ao nascer, aleitamento materno, número de crianças no domicílio, frequência em creche, presença de animais de estimação no domicílio e cuidador tabagista. A prevalência de SR foi duas vezes maior entre crianças com displasia broncopulmonar (OR ajustada = 2,08; IC95%: 1,11-3,89; p = 0,022) e quase cinco vezes maior entre aquelas com história pessoal/familiar de atopia (OR ajustada = 4,96; IC95%: 2,62-9,39; p < 0,001) do que entre aquelas sem essas condições. Conclusões: Crianças pré-termo que receberam profilaxia com palivizumabe, mas apresentam história pessoal/familiar de atopia ou displasia broncopulmonar, têm maior probabilidade de apresentar SR do que aquelas sem essas condições.

ABSTRACT

Bronchial asthma is a common chronic respiratory disease,and its diagnosis is mainly based on symptoms,signs,and pulmonary function test.Wheezing is a major symptom of asthma attack,which shows no obvious sign in the early stage while appears after the disease has progressed.Therefore,bronchial asthma is difficult to be detected in early stages,which often leads to worsening of the disease conditions.Pulmonary function test can effectively monitor upper and lower airway abnormalities and is currently the main means for monitoring asthma.However,its accuracy is highly dependent on patient's motivation and cooperation,which obviously limits the scope of application,especially for preschoolers and infants.Hence,there is an urgent need for a new technology with the function of long-term breath sound monitoring and automatic breathing detection to overcome the existing clinical deficiencies.Breath sound analysis emerges in the era of medical artificial intelligence,which can digitally process and convert the collected respiratory sounds by using a variety of different methods to form characteristic signal parameters and model the relationship between parameters and diseases.As we know,breath sounds are closely related to airway changes,and thus the detection and analysis of the sounds can provide reliable clinical information for the progress and control evaluation of asthma.This review mainly summaries the research progress of respiratory sound analysis in recent years,hoping to provide reference for further research.

ABSTRACT

OBJECTIVE@#Most patients with recurrent wheezing are infants under 2 years of age. Clinical prediction models of the risk of receiving airway support during the hospital stay in this population have been poorly studied in tropical countries. This study aimed to evaluate the clinical predictors of hospitalization plus airway support among infants with recurrent wheezing evaluated in the emergency department in Colombia.@*METHODS@#A retrospective cohort study was performed. This study included all infants with two or more wheezing episodes who were younger than two years old in two tertiary centers in Rionegro, Colombia, between January 2019 and December 2019. The primary outcome measure was hospitalization plus any airway support. A multivariable logistic regression model was used to identify factors independently associated with hospitalization plus any airway support.@*RESULTS@#A total of 85 infants were hospitalized plus any airway support, of whom 34(40%) were treated with high flow nasal canula, 2(2%) received non-invasive ventilation, 6(7%) were mechanically ventilated, and 43 (51%) received conventional oxygen therapy. The multivariable logistic regression model showed that predictors of hospitalization plus airway support included prematurity (@*CONCLUSIONS@#The present study shows that prematurity, poor feeding, nasal flaring and/or grunting, and more than one previous episode of wheezing requiring hospitalization are independent predictors of hospitalization plus airway support in a population of infants with recurrent wheezing in the emergency department. More evidence must be collected to examine the results in other tropical countries.

ABSTRACT

RESUMO: Objetivo: Mensurar o nível de controle da asma em estudantes com relato de chiado no peito no último ano através do Asthma Control Test (ACT). Método: Estudo transversal descritivo realizado com ingressantes na Universidade Federal de Pelotas (UFPel) em 2017, incluindo 1.865 universitários com 18 anos ou mais. Resultados: Cerca de 19% dos universitários apresentaram chiado no peito nos 12 meses que antecederam a entrevista. Destes, 14% apresentaram asma não controlada (ACT ≤18 pontos). A maior prevalência de asma não controlada foi observada no sexo feminino, em indivíduos com 24 anos ou mais, com a cor da pele parda, em um quarto dos universitários pertencentes às classes D e E, e naqueles que não fumam e não consomem bebida alcoólica. Conclusão: Apesar de a população estudada ser composta por universitários, observou-se uma prevalência expressiva de asma não controlada.

ABSTRACT

SUMMARY OBJECTIVES: To evaluate the treatment of wheezing and exacerbation of asthma in a pediatric emergency unit (ED), comparing it to that recommended by the guidelines for this purpose. METHODS: Descriptive cross-sectional study through medical records survey of children and adolescents (0-15 years of age) who received medication for wheezing or asthma exacerbation from January to April 2015 in the ED. The selected treatment was compared to that recommended by the guidelines, being analyzed the variables related to the medication (number and dose of short-acting β2 agonist, associated or not with anticholinergic, oral or parenteral corticosteroid) and the length of stay in ED (≤1 h, ≥8 h and hospital admission). RESULTS: One-thousand eleven patients were selected with 56.7% between 3 and 15 years and 56% male. Although the selected drugs were in accordance with what was recommended, errors were observed in relation to dose, drug of choice, and method and time of use with the most frequent finding being incorrect dose (short-acting β2 agonist: 66% and ipratropium bromide: 95.2%). CONCLUSION: The level of use of the measures recommended by the guidelines was low but compatible with other studies, leading to an increased risk of treatment failure and higher costs. Despite wide dissemination, the established concepts have not been sufficiently incorporated into clinical practice, suggesting the need for more effective educational actions for this process to occur.


RESUMO OBJETIVOS: Avaliar o tratamento da sibilância e da exacerbação da asma em unidade de emergência pediátrica (DE), comparando-o ao recomendado pelas diretrizes para esse fim. MÉTODOS: Estudo descritivo transversal, por meio do levantamento de prontuários de crianças e adolescentes (0 - 15 anos de idade) que receberam medicação para sibilância ou exacerbação da asma, no período de janeiro a abril de 2015, em DE. O tratamento empregado foi comparado ao preconizado pelas diretrizes sendo analisadas as variáveis referentes à medicação (número e dose de β2 agonista de curta ação, associado ou não a anticolinérgico, corticosteroide oral ou parenteral) e ao tempo de permanência na DE (≤1 h, ≥8 h e internação hospitalar). RESULTADOS: Foram selecionados 1011 pacientes, 56,7% com idades entre 3 e 15 anos e 56 % do sexo masculino. Embora os fármacos utilizados estivessem de acordo com o preconizado, foram observados erros com relação a dose, droga de escolha, forma de utilização, tempo de uso, sendo dose incorreta o achado mais frequente (β2 agonista de curta ação: 66% e brometo de ipratrópio: 95,2%). CONCLUSÃO: O nível de utilização das medidas recomendadas pelas diretrizes foi baixo e compatível com outros estudos, levando a risco aumentado de falha no tratamento e maior custo. Apesar da ampla divulgação, os conceitos estabelecidos não são suficientemente incorporados à prática clínica, sugerindo a necessidade de ações educativas mais efetivas para que isso ocorra.

ABSTRACT

La auscultación pulmonar es parte fundamental del examen físico para el diagnóstico de las enfermedades respiratorias. La estandarización que ha alcanzado la nomenclatura de los ruidos respiratorios, sumado a los avances en el análisis computacional de los mismos, han permitido mejorar la utilidad de esta técnica. Sin embargo, el rendimiento de la auscultación pulmonar ha sido cuestionado por tener una concordancia variable entre profesionales de la salud. Aun cuando la incorporación de nuevas herramientas diagnósticas de imágenes y función pulmonar han revolucionado la precisión diagnóstica en enfermedades respiratorias, no existe tecnología que permita reemplazar la técnica de auscultación pulmonar para guiar el proceso diagnóstico. Por una parte, la auscultación pulmonar permite seleccionar a aquellos pacientes que se beneficiarán de una determinada técnica diagnóstica, se puede repetir cuantas veces sea necesario para tomar decisiones clínicas, y frecuentemente permite prescindir de exámenes adicionales que no siempre son fáciles de realizar o no se encuentran disponibles. En esta revisión se presenta el estado actual de la técnica de auscultación pulmonar y su rendimiento objetivo basado en la nomenclatura actual aceptada para los ruidos respiratorios, además de resumir la evidencia principal de estudios de concordancia de auscultación pediátrica y su análisis objetivo a través de nueva tecnología computacional.


Lung auscultation is an essential part of the physical examination for diagnosing respiratory diseases. The terminology standardization for lung sounds, in addition to advances in their analysis through new technologies, have improved the use of this technique. However, traditional auscultation has been questioned due to the limited concordance among health professionals. Despite the revolu tionary use of new diagnostic tools of imaging and lung function tests allowing diagnostic accuracy in respiratory diseases, no technology can replace lung auscultation to guide the diagnostic process. Lung auscultation allows identifying those patients who may benefit from a specific test. Moreover, this technique can be performed many times to make clinical decisions, and often with no need for- complicated and sometimes unavailable tests. This review describes the current state-of-the-art of lung auscultation and its efficacy based on the current respiratory sound terminology. In addition, it describes the main evidence on respiratory sound concordance studies among health professionals and its objective analysis through new technology.

ABSTRACT

RESUMO Na unidade de terapia intensiva (UTI) pediátrica, a falha de extubação pode aumentar o risco de mortalidade. Este estudo objetivou: (1) verificar a taxa de falha de extubação na UTI pediátrica de um hospital público do município de Bauru (São Paulo, Brasil); (2) identificar a principal causa atribuída à falha de extubação; (3) avaliar se características como a idade e o tempo de ventilação mecânica invasiva (VMI) estão associadas à falha de extubação; (4) avaliar se o tempo de permanência na UTI e hospital é maior entre os pacientes que apresentaram falha de extubação. Foi realizado estudo de coorte retrospectivo com 89 pacientes internados de maio de 2017 até julho de 2018. Os resultados mostraram taxa de falha de extubação correspondente a 16%. A principal causa atribuída à falha de extubação foi o estridor laríngeo, totalizando 57% dos casos. A comparação intergrupos (sucesso vs. falha de extubação) não mostrou diferenças em relação à idade (p=0,294) e ao tempo de VMI (p=0,228). No entanto, observamos que o grupo falha de extubação apresentou maior tempo de UTI (p=0,000) e hospital (p=0,010). Desta forma, concluímos que a taxa de extubação está de acordo com a observada em outros estudos. O estridor laríngeo foi responsável por mais da metade dos casos de falha de extubação. Embora a idade e o tempo de VMI não tenham sido características associadas à falha de extubação, esta contribuiu para o maior período de permanência na UTI e no hospital.


RESUMEN En la unidad de cuidados intensivos (UCI) pediátrica, el fracaso de la extubación puede aumentar el riesgo de mortalidad. Este estudio tuvo el objetivo de: (1) verificar el índice de fracaso de la extubación en la UCI pediátrica de un hospital público en el municipio de Bauru (São Paulo, Brasil); (2) identificar la causa principal atribuida al fracaso de la extubación; (3) evaluar si las características edad y tiempo de ventilación mecánica invasiva (VMI) están asociadas al fracaso de la extubación; (4) evaluar si la duración en la UCI y el hospital es mayor entre los pacientes que experimentaron este fracaso. Se realizó un estudio de cohorte retrospectivo con 89 pacientes hospitalizados desde mayo de 2017 hasta julio de 2018. Los índices del fracaso de la extubación fueron del 16%. El estridor laríngeo fue la causa principal atribuida al fracaso de la extubación, lo que totaliza el 57% de los casos. La comparación intergrupal (éxito versus fracaso de la extubación) no presentó diferencias en relación con la edad (p=0,294) y el tiempo VMI (p=0,228). Se observó que el grupo fracaso de la extubación estuvo más tiempo en la UCI (p=0,000) y el hospital (p=0,010). Se concluye que el índice de extubación está en consonancia con lo observado en otros estudios. El estridor laríngeo fue el responsable de más de la mitad de los casos de fracaso de la extubación. Las características edad y el tiempo de VMI no estuvieron asociadas al fracaso de la extubación, pero esta contribuyó a un período más prolongado en la UCI y en el hospital.


ABSTRACT In the pediatric intensive care unit (ICU), extubation failure may increase mortality risk. This study aimed: (1) to verify the rate of extubation failure in the pediatric ICU of a public hospital located in the city of Bauru (São Paulo, Brazil); (2) to identify the main cause attributed to extubation failure; (3) to evaluate whether age and time of invasive mechanical ventilation (IMV) are characteristics associated to extubation failure; (4) to evaluate whether the length of stay in the ICU/hospital is longer among patients who presented extubation failure. A retrospective study was performed with 89 hospitalized patients from May 2017 to July 2018. Results showed an extubation failure rate corresponding to 16%. The main cause attributed to extubation failure was laryngeal stridor, totaling 57% of the cases. Intergroup comparison (success vs. failure of extubation) showed no differences in relation to age (p=0.294) and IMV time (p=0.228). However, we observed that the extubation failure group had longer ICU (p=0.000) and hospital time (p=0.010). In this way, we conclude that the rate of extubation failure is in agreement with other studies. Laryngeal stridor was responsible for more than half of cases of extubation failure. Although IMV time and age were not associated with the extubation failure, they contributed to a longer stay in the ICU and in the hospital.

ABSTRACT

RESUMO Objetivo Uma proporção significativa de lactentes desenvolve sibilância recorrente após um evento de bronquiolite aguda (BA). Estudos recentes demonstraram proteção para sibilância recorrente e menor morbidade respiratória em lactentes tratados com azitromicina durante uma crise de sibilância. O objetivo do presente estudo foi testar a hipótese de que a administração de azitromicina durante um evento BA reduz sibilos e reinternações hospitalares subsequentes. Métodos Trata-se de uma análise secundária de um estudo randomizado, duplo-cego, controlado por placebo, incluindo dados não publicados de sibilância e hospitalizações durante os seis meses iniciais após a internação por bronquiolite aguda. O estudo foi realizado em um hospital universitário terciário. Os bebês (<12 meses de idade) hospitalizados com BA foram randomizados para receber azitromicina ou placebo, administrados por via oral, por sete dias. As famílias foram contatadas por telefone aos três e seis meses após o evento agudo inicial, e responderam a um questionário padronizado para identificar sibilos recorrentes e reinternações hospitalares. Resultados Cento e quatro pacientes foram incluídos (grupo Azitromicina, n=50; grupo Placebo, n=54). Considerando o total de pacientes contatados com sucesso três meses após a hospitalização (n=70), a taxa de recorrência de sibilância no grupo da azitromicina foi significativamente menor do que no grupo placebo (RR=0,48; CI=0,24-0.98; p=0,038). Conclusões A azitromicina reduziu significativamente o risco de sibilância subsequente entre zero e três meses após a admissão hospitalar por bronquiolite aguda.


ABSTRACT Objective A significant proportion of the infants developed recurrent wheezing after an acute bronchiolitis (AB) event. Recent studies have demonstrated protection for recurrent wheeze and lower respiratory morbidity in infants treated with azithromycin during an acute respiratory wheezing. The aim of the present study was to test the hypothesis that administration of azithromycin during an AB event reduces subsequent wheezing and hospital re-admissions. Methods This is a secondary analysis of a randomized, double-blinded, placebo-controlled trial, including unpublished data of wheezing and hospitalizations during the initial 6 months following admission for acute viral bronchiolitis. The study was performed in a tertiary University hospital. Infants (<12 months of age) hospitalized with AB were randomized to receive either azithromycin or placebo, administered orally, for 7 days. Families were contacted by telephone at 3 and 6 months after the initial acute event and answered to a standardized questionnaire in order to identify recurrent wheezing and hospital readmissions. Results One hundred and four patients were included (Azithromycin group, n= 50; placebo group, n=54). Considering the total of patients contacted 3 months after hospitalization (n=70), the recurrence rate of wheezing in the azithromycin group was significantly lower than in the placebo group (RR = 0.48; CI = 0.24-0.98; p = 0.038). Conclusion Azithromycin significantly reduces the risk of subsequent wheezing between 0 and 3 months after hospital admission due to acute bronchiolitis irrespective of the presence of respiratory syncytial virus.

ABSTRACT

ABSTRACT Objective: To estimate the prevalence of respiratory symptoms and asthma, according to body mass index (BMI), as well as to evaluate factors associated with physician-diagnosed asthma, in individuals ≥ 40 years of age. Methods: This was a population-based cross-sectional study conducted in Florianópolis, Brazil, with probability sampling. Data were collected during home visits. Demographic data were collected, as were reports of physician-diagnosed asthma, respiratory symptoms, medications in use, and comorbidities. Anthropometric measurements were taken. Individuals also underwent spirometry before and after bronchodilator administration. Individuals were categorized as being of normal weight (BMI < 25 kg/m2), overweight (25 kg/m2 ≥ BMI < 30 kg/m2), or obese (BMI ≥ 30 kg/m2). Results: A total of 1,026 individuals were evaluated, 274 (26.7%) were of normal weight, 436 (42.5%) were overweight, and 316 (30.8%) were obese. The prevalence of physician-diagnosed asthma was 11.0%. The prevalence of obesity was higher in women (p = 0.03), as it was in respondents with ≤ 4 years of schooling (p < 0.001) or a family income of 3-10 times the national minimum wage. Physician-diagnosed asthma was more common among obese individuals than among those who were overweight and those of normal weight (16.1%, 9.9%, and 8.0%, respectively; p = 0.04), as were dyspnea (35.5%, 22.5%, and 17.9%, respectively; p < 0.001) and wheezing in the last year (25.6%, 11.9%, and 14.6%, respectively; p < 0.001). These results were independent of patient smoking status. In addition, obese individuals were three times more likely to report physician-diagnosed asthma than were those of normal weight (p = 0.005). Conclusions: A report of physician-diagnosed asthma showed a significant association with being ≥ 40 years of age and with having a BMI ≥ 30 kg/m2. Being obese tripled the chance of physician-diagnosed asthma.


RESUMO Objetivo: Estimar a prevalência de sintomas respiratórios e asma de acordo com o índice de massa corpórea (IMC) em indivíduos com idade ≥ 40 anos e avaliar os fatores associados ao relato de diagnóstico médico de asma. Métodos: Estudo transversal de base populacional realizado no município de Florianópolis (SC), com coleta domiciliar de dados e processo de amostragem probabilístico. Foram coletadas informações demográficas, assim como sobre relato de diagnóstico médico de asma, sintomas respiratórios, medicações em uso e comorbidades. Também foram realizadas medidas antropométricas e espirometria pré- e pós-broncodilatador. O IMC foi categorizado em normal (IMC < 25 kg/m2), sobrepeso (25 kg/m2 ≥ IMC < 30 kg/m2) e obesidade (IMC ≥ 30 kg/m2). Resultados: Foram avaliados 1.026 indivíduos, 274 (26,7%) com IMC normal, 436 (42,5%) com sobrepeso e 316 (30,8%) obesos. A prevalência de diagnóstico médico de asma foi de 11,0%. A prevalência de obesidade foi maior em mulheres (p = 0,03) e em entrevistados com escolaridade < 4 anos (p < 0,001) ou com renda familiar entre 3-10 salários mínimos. Obesos, quando comparados com aqueles com sobrepeso e peso normal, relataram mais frequentemente diagnóstico médico de asma (16,1%, 9,9% e 8,0%, respectivamente; p = 0,04), dispneia (35,5%, 22,5% e 17,9%, respectivamente; p < 0,001) e sibilos no último ano (25,6%, 11,9% e 14,6%, respectivamente; p < 0,001). Esses resultados foram independentes do status tabágico. Além disso, obesos tinham uma chance três vezes maior de relato de diagnóstico médico de asma do que não obesos (p = 0,005). Conclusões: Houve associação significativa entre o relato de diagnóstico médico de asma em indivíduos com idade ≥ 40 anos e IMC ≥ 30 kg/m2. Ser obeso triplicou a chance de diagnóstico médico de asma.

ABSTRACT

OBJECTIVE@#To study the expression level of cAMP response element-binding protein (CREB) in children with recurrent wheezing under three years of age and its effect on the expression of the serum orosomucoid 1-like protein 3 (ORMDL3) gene.@*METHODS@#Thirty-six children with recurrent wheezing under three years of age who visited the hospital from June 2017 to June 2019 were selected as the recurrent wheezing group. Twenty-four healthy children from physical examination were selected as the control group. The CREB expression level in peripheral blood was measured by quantitative real-time PCR. Human bronchial epithelial cells (BEAS-2B) were cultured, and dual-luciferase reporter assay and quantitative real-time PCR were used to investigate the effects of overexpression and siRNA interference of CREB on the promoter activity and mRNA expression of the ORMDL3 gene in the BEAS-2B cells.@*RESULTS@#The expression level of CREB in the recurrent wheezing group was significantly higher than that in the control group (P<0.001). In BEAS-2B cells, overexpression of CREB significantly up-regulated the promoter activity and mRNA expression of the ORMDL3 gene (P<0.05), while siRNA interference of CREB significantly reduced the promoter activity and mRNA expression of the ORMDL3 gene (P<0.05).@*CONCLUSIONS@#The expression of CREB is increased in children with recurrent wheezing, and CREB may be involved in the pathogenesis of recurrent wheezing by regulating expression of the ORMDL3 gene.

ABSTRACT

ABSTRACT Objective: To evaluate the prevalence and risk factors associated with progression to recurrent wheezing in preterm infants. Methods: The cross-sectional study was carried out in 2014 and 2015 and analyzed preterm infants born between 2011 and 2012. The search for these children was performed in a university maternity hospital and a Special Immunobiological Reference Center. The evaluation was performed through a questionnaire applied during a telephone interview. Results: The study included 445 children aged 39 (18-54) months. In the univariate analysis, the risk factors with the greatest chance of recurrent wheezing were birth weight <1000 g, gestational age <28 weeks, living with two or more siblings, food allergy, and atopic dermatitis in the child, as well as food allergy and asthma in the parents. In the multivariate analysis, there was a significant association between recurrent wheezing and gestational age at birth <28 weeks, food allergy and atopic dermatitis in the child, and living with two or more children. Of the 445 analyzed subjects, 194 received passive immunization against the respiratory syncytial virus, and 251 preterm infants were not immunized. There was a difference between the gestational age of these subgroups (p < 0.001). The overall prevalence of recurrent wheezing was 27.4% (95% CI: 23.42-31.70), whereas in the children who received passive immunization it was 36.1% (95% CI: 29.55-43.03). Conclusions: Personal history of atopy, lower gestational age, and living with two or more children had a significant association with recurrent wheezing. Children with lower gestational age who received passive immunization against the respiratory syncytial virus had a higher prevalence of recurrent wheezing than the group with higher gestational age.


RESUMO Objetivo: Avaliar a prevalência e os fatores de risco associados à evolução para sibilância recorrente em prematuros. Métodos: O estudo transversal foi feito em 2014 e 2015 e analisou crianças prematuras nascidas entre 2011 e 2012. A busca dessas crianças foi feita em maternidade de hospital universitário e em um Centro de Referência para Imunobiológicos Especiais. A avaliação foi feita por questionário dirigido em entrevista telefônica. Resultados: O estudo incluiu 445 crianças com 39 (18-54) meses de vida. Na análise univariada, os fatores de risco com maior chance de sibilância recorrente foram peso de nascimento menor do que 1.000 g, idade gestacional menor do que 28 semanas, convivência com dois ou mais irmãos, alergia alimentar e dermatite atópica na criança e alergia alimentar e asma nos pais. Na análise multivariada houve associação significativa entre sibilância recorrente e idade gestacional ao nascer menor do que 28 semanas, alergia alimentar e dermatite atópica na criança e a convivência com duas ou mais crianças. Dos 445 sujeitos analisados, 194 receberam imunização passiva contra vírus sincicial respiratório e 251 eram prematuros não imunizados. Houve diferença entre a idade gestacional desses subgrupos (p < 0,001). A prevalência geral de sibilância recorrente foi 27,4% (IC 95%: 23,42-31,70) e nas crianças que receberam a imunização passiva foi 36,1% (IC 95%: 29,55-43,03). Conclusões: História pessoal de atopia, menor idade gestacional e convivência com duas ou mais crianças apresentaram associação significativa com sibilância recorrente. As crianças com menor idade gestacional, que receberam a imunização passiva contra o vírus sincicial respiratório, apresentaram maior prevalência de sibilância recorrente que o grupo de maior idade gestacional.

ABSTRACT

La granulomatosis con poliangeítis antes denominada con el epónimo de granulomatosis de Wegener, clasifica entre las vasculitis sistémicas, de causa desconocida, que afecta a los vasos de pequeño y mediano calibre. Se caracteriza por la afectación del aparato respiratorio en su tracto superior, pulmones, así como a los riñones, aunque puede afectar a otros órganos y sistemas del organismo humano. Los anticuerpos anti citoplasma de neutrófilos son positivos con una frecuencia que alcanza el 80 por ciento de casos, y la característica histológica más relevante es la presencia de lesiones granulomatosas necrosantes. El diagnóstico se basa en las manifestaciones clínicas, la biopsia con estudio histológico de los tejidos y órganos afectados así como la presencia de anticuerpos anti citoplasma de neutrófilos. Hoy en día se agrupa dentro de las denominadas vasculitis asociadas a anticuerpos anti citoplasma de neutrófilos positivas. Nuestro estudio tuvo como objetivo presentar un caso clínico inusual, en el cual reportamos a una paciente de 55 años de edad la cual fue atendida por presentar manifestaciones clínicas, de laboratorio y radiológicas que permiten confirmar el diagnóstico de una Granulomatosis de Wegener. Su forma clínica de expresión inicial mostró. una serie de signos y síntomas constitucionales como fiebre superior de 38 grados de varios días de evolución en horario vespertino, astenia, pérdida de apetito, artromialgias, manifestaciones respiratorias como dolor torácico e intercostal izquierdo, tos con expectoración mucosa, y disnea a esfuerzos físicos en aumento. Al examen físico se recogieron datos positivos como palidez cutánea mucosa, la presencia de disminución del murmullo vesicular a nivel del vértice del pulmón izquierdo con estertores crepitantes y una imagen a modo de masa tumoral redondeada del lóbulo superior del pulmón que orientaba al diagnóstico de una neoplasia de vértice de pulmón. Se realizaron múltiples estudios considerando el proteiforme cuadro clínico, los estudios inmunológicos realizados, y la histología por biopsia pulmonar, los que demostraron la existencia de lesiones de tipo granulomatosas compatibles con G. Wegener. Resultó efectiva la respuesta terapéutica con drogas esteroideas e inmunosupresoras en forma de bolos de ciclofosfamida acompañados de un fuerte tratamiento antibiótico de amplio espectro. Concluimos que se trata de un raro caso de granulomatosis de Wegener cuya forma de debut hizo plantear el diagnóstico inicial de una lesión tumoral de vértice de pulmón. No conocemos de otro caso similar reportado en nuestro medio(AU)


Granulomatosis with polyangiitis, formerly known as Wegener's Granulomatosis, is classified as systemic vasculitis, of unknown cause, affecting small and medium-sized vessels. It is characterized by the involvement of the respiratory system in its upper tract, lungs, as well as the kidneys, although it can affect other organs and systems. Neutrophil anticithoplasma antibodies are positive with a frequency that reaches over 80 percent of cases, and the most relevant histological feature is the presence of necrotizing granulomatous lesions. The diagnosis is based on clinical manifestations, biopsy with histological study of the affected tissues and organs as well as the presence of Neutrophil anticithoplasma antibodies. Nowadays it is grouped into the so-called Neutrophil anticithoplasma antibodies positive vasculitis. Arthromyalgia, respiratory manifestations such as thoracic and left intercostal pain, cough with mucous expectoration, and dyspnea on physical efforts in increase. The physical examination collected positive data such as mucous skin pallor, the presence of decreased vesicular murmur at the level of the left vertex of the lung with crackling rales and an image as a rounded tumor mass of the upper lobe of the lung that guided the diagnosis of a vertex neoplasm of lung. Multiple studies were carried out considering the proteiform clinical picture, the immunological studies performed, and the lung biopsy histology, which demonstrated the existence of granulomatous lesions compatible with G. Wegener. The therapeutic response was effective with steroidal and immunosuppressive drugs in the form of cyclophosphamide boluses accompanied by a strong broad-spectrum antibiotic treatment. We conclude that this is a rare case of Wegener's granulomatosis, whose debut form raised the initial diagnosis of a tumor of the lung vertex. We do not know of another similar case reported in our country(AU)
