Maternal Near Miss in Patients with Systemic Lupus Erythematosus / Near miss materno em pacientes com lupus eritematoso sistêmico

Abstract Objective Systemic lupus erythematosus (SLE) may cause irreversible organ damage. Pregnancy with SLE may have severe life-threatening risks. The present study aimed to determine the prevalence of severe maternal morbidity (SMM) in patients with SLE and analyze the parameters that contributed to cases of greater severity. Methods This is a cross-sectional retrospective study from analysis of data retrieved from medical records of pregnant women with SLE treated at a University Hospital in Brazil. The pregnant women were divided in a control group without complications, a group with potentially life-threatening conditions (PLTC), and a group with maternal near miss (MNM). Results The maternal near miss rate was 112.9 per 1,000 live births. The majority of PLTC (83.9%) and MNM (92.9%) cases had preterm deliveries with statistically significant increased risk compared with the control group (p = 0.0042; odds ratio [OR]: 12.05; 95% confidence interval [CI]: 1.5-96.6 for the MNM group and p = 0.0001; OR: 4.84; 95%CI: 2.2-10.8 for the PLTC group). Severe maternal morbidity increases the risk of longer hospitalization (p < 0.0001; OR: 18.8; 95%CI: 7.0-50.6 and p < 0.0001; OR: 158.17; 95%CI: 17.6-1424,2 for the PLTC and MNM groups, respectively), newborns with low birthweight (p = 0.0006; OR: 3.67; 95%CI: 1.7-7.9 and p = 0.0009; OR: 17.68; 95%CI: 2-153.6) for the PLTC and MNM groups, respectively] as well as renal diseases (PLTC [8.9%; 33/56; p = 0.0069] and MNM [78.6%; 11/14; p = 0.0026]). Maternal near miss cases presented increased risk for neonatal death (p = 0.0128; OR: 38.4; 95%CI: 3.3-440.3]), and stillbirth and miscarriage (p = 0.0011; OR: 7.68; 95%CI: 2.2-26.3]). Conclusion Systemic lupus erythematosus was significantly associated with severe maternal morbidity, longer hospitalizations, and increased risk of poor obstetric and neonatal outcomes.

Resumo Objetivo Lúpus eritematoso sistêmico (LES) pode causar danos irreversíveis aos órgãos. A gravidez com LES pode ter riscos para condições ameaçadoras à vida. O presente estudo teve como objetivo determinar a prevalência de MMG em pacientes com LES e analisar os parâmetros que contribuíram para os casos de maior gravidade. Métodos Trata-se de um estudo transversal retrospectivo a partir da análise de dados obtidos de prontuários de gestantes com LES atendidas em um Hospital Universitário no Brasil. As gestantes foram divididas em grupo controle sem intercorrências, grupo com condições potencialmente ameaçadoras a vida (CPAV) e grupo com near miss materno (NMM). Resultados A taxa de NMM foi de 112,9 por 1.000 nascidos vivos. A maioria dos casos de CPAV (83,9%) e NMM (92,9%) teve partos prematuros com risco aumentado estatisticamente significativo em comparação com o grupo controle (p = 0,0042; odds ratio [OR]: 12,05; intervalo de confiança [IC]: 1,5-96,6 para o grupo NMM e p = 0,0001; OR: 4,84; IC95%: 2,2-10,8 para o grupo CPAV). MMG aumenta o risco de maior tempo de internação (p < 0,0001; OR: 18,8; IC95%: 7,0-50,6 e p < 0,0001; OR: 158,17; IC95%: 17,6-1424,2 para os grupos CPAV e NMM, respectivamente), recémnascidos com baixo peso (p = 0,0006; OR: 3,67; IC95%: 1,7-7,9 e p = 0,0009; OR: 17,68; IC95%: 2-153,6 para os grupos CPAV e NMM, respectivamente), bem como doenças renais (CPAV: 58,9%; 33/56; p = 0,0069 e NMM: 78,6%; 11/14; p = 0,0026)]. Os casos de NMM apresentaram risco aumentado para óbito neonatal (p = 0,0128; OR: 38,4; IC95%: 3,3-440,3), natimorto e aborto espontâneo (p = 0,0011; OR: 7,68; IC95%: 2,2-26,3). Conclusão Lúpus eritematoso sistêmico foi significativamente associado à morbidade materna grave, internações mais longas e risco aumentado de desfechos obstétricos e neonatais ruins.

Intervenções psicológicas necessárias: a prática como residente no serviço de medicina fetal / Necessary psychological interventions: the practice as a resident in the fetal medicine service / Intervenciones psicológicas necesarias: la práctica como residente en el servicio de medicina fetal

Com os avanços tecnológicos e o aprimoramento da prática médica via ultrassonografia, já é possível detectar possíveis problemas no feto desde a gestação. O objetivo deste estudo foi analisar a prática do psicólogo no contexto de gestações que envolvem riscos fetais. Trata-se de um estudo qualitativo sob formato de relato de experiência como psicólogo residente no Serviço de Medicina Fetal da Maternidade Escola da Universidade Federal do Rio de Janeiro (UFRJ). Os registros, feitos por observação participante e diário de campo, foram analisados em dois eixos temáticos: 1) intervenções psicológicas no trabalho em equipe em consulta de pré-natal, exame de ultrassonografia e procedimento de amniocentese; e 2) intervenções psicológicas em casos de bebês incompatíveis com a vida. Os resultados indicaram que o psicólogo nesse serviço é essencial para atuar de forma multiprofissional na assistência pré-natal para gravidezes de alto risco fetal. Ademais, a preceptoria do residente é relevante para sua formação e treinamento para atuação profissional no campo da psicologia perinatal.(AU)

Face to the technological advances and the improvement of medical practice via ultrasound, it is already possible to detect possible problems in the fetus since pregnancy. The objective of this study was to analyze the psychologist's practice in the context of pregnancies which involve fetal risks. It is a qualitative study based on an experience report as a psychologist trainee at the Fetal Medicine Service of the Maternity School of UFRJ. The records, based on the participant observation and field diary, were analyzed in two thematic axes: 1) psychological interventions in the teamwork in the prenatal attendance, ultrasound examination and amniocentesis procedure; and 2) psychological interventions in cases of babies incompatible to the life. The results indicated that the psychologist in this service is essential to work in a multidisciplinary way at the prenatal care for high fetal risk pregnancies. Furthermore, the resident's preceptorship is relevant to their education and training for professional performance in the field of Perinatal Psychology.(AU)

El objetivo de este estudio fue analizar la práctica del psicólogo en el contexto de embarazos de riesgos fetal. Es un estudio cualitativo basado en un relato de experiencia como residente de psicología en el Servicio de Medicina Fetal de la Escuela de Maternidad de la Universidade Federal do Rio de Janeiro (UFRJ). Los registros, realizados en la observación participante y el diario de campo, se analizaron en dos ejes temáticos: 1) intervenciones psicológicas en el trabajo en equipo, en la consulta prenatal, ecografía y los procedimientos de amniocentesis; y 2) intervenciones psicológicas en casos de bebés incompatibles con la vida. Los resultados señalaron como fundamental la presencia del psicólogo en este servicio trabajando de forma multidisciplinar en la atención prenatal en el contexto de embarazos de alto riesgo fetal. Además, la tutela del residente es relevante para su educación y formación para el desempeño profesional en el campo de la Psicología Perinatal.(AU)

Análisis de causas atribuidas a "BRUE" entre los años 2017 a 2020 / Analysis of etiologies attributed to "BRUE" between the years 2017 to 2020

El término BRUE describe un evento en un lactante menor, repentino, breve, ya resuelto y sólo aplica cuando no existe una explicación para este episodio. Es escasa la literatura nacional e internacional sobre el estudio etiológico en BRUE. Objetivos: Caracterizar lactantes con episodio de BRUE y hacer un análisis etiológico. Métodos: Estudio retrospectivo, descriptivo lactantes hospitalizados por BRUE. Resultados: Se encontraron 50 lactantes con BRUE, la mayoría de ellos presentó un solo evento y ninguno requirió reanimación cardiopulmonar. Las características principales de los eventos fueron apnea, cianosis y tono disminuido. Las etiologías encontradas, más habituales, fueron reflujo gastro-esofágico, infección respiratoria, mala técnica alimentaria y crisis epilépticas. La evaluación clínica fue el principal elemento diagnóstico. Discusión: Nuestro análisis etiológico concuerda con la literatura nacional e internacional. La anamnesis y examen físico son la principal herramienta diagnóstica. Es fundamental contar con guías, adaptadas a la realidad nacional y local, que dirijan el estudio de lactantes con BRUE.

BRUE is an event occurring in an infant when the observer reports a sudden, brief, and now-resolved episode. BRUE is a diagnosis of exclusion and is used only when there is no explanation for the event after conducting an appropriate history and physical examination. There is little literature on the etiological study in BRUE. Objectives: To characterize infants with a BRUE episode and to carry out an etiological analysis. Methods: A retrospective study including infants who have experienced a BRUE between the years 2017 to 2020. Results: 50 infants with BRUE, most of them presented a single event and none required cardiopulmonary resuscitation. The main characteristics of the events were apnea, cyanosis and decreased tone. The most common etiologies found were gastroesophageal reflux, respiratory infection, poor feeding technique, and seizures. History and physical examination are the fundamental diagnostic tools. Discussion: Our etiological analysis agrees with the national and international literature. The clinical evaluation was the main diagnostic tool. It is essential to create local guidelines for the evaluation investigation and management of infants with BRUE.

Pacientes con diagnóstico de "BRUE" atendidos en hospital pediátrico chileno. Aplicando nueva terminología / Patients with diagnosis of "Sids" treated in chilean pediatric hospital. Applying new terminology

La posible relación entre apneas durante la infancia temprana y Síndrome de Muerte Súbita del Lactante (SMSL) nunca ha sido demostrada, existiendo evidencias de que ambas condiciones podrían no estar relacionadas. La Academia Americana de Pediatría (AAP) define ALTE (Acute Life Threatening Event), como un evento brusco e inesperado que incluye manifestaciones de apnea junto con cambios de coloración cutánea y de tono muscular, donde el observador cree que el niño ha muerto. La AAP ha propuesto recientemente la sustitución del término ALTE por Brief Resolved Unexplained Events (BRUE). El nuevo concepto permite categorizar eventos breves, resueltos e inexplicados, para optimizar mejor el recurso en salud, a través de objetivar el evento y entregando estrategias de manejo categorizando el riesgo. Objetivo: Describir las características clínicas y letalidad de los pacientes menores de 12 meses que consultan por BRUE en un hospital de referencia. Materiales y métodos: Estudio transversal descriptivo con revisión de ficha de 46 pacientes de la Unidad de Lactantes y Nutrición del Hospital Dr. Luis Calvo Mackenna, con diagnóstico de BRUE, entre enero a diciembre de 2017. Resultados: Del total de pacientes con BRUE, 45% fueron hombres y 55% mujeres. La edad promedio fue de 1,37 + 0,51 meses. En 70% se demostró una etiología, de estas 31% con enfermedad por reflujo gastroesofágico (ERGE), siendo ésta la causa más frecuente seguida de un 19% con infecciones respiratorias agudas (IRA) y 9% causas neurológicas. En el 30% fueron causas idiopáticas. Conclusión: En nuestro estudio las causas más frecuentes de BRUE fueron ERGE e infecciones respiratorias. Durante el período de estudio ningún paciente estudiado falleció, por lo que no encontramos relación entre apneas del lactante y síndrome de muerte súbita.

The possible relationship between apneas during early childhood and Sudden Infant Death Syndrome (SIDS) has never been demonstrated, and there is evidence that the two conditions may not be related. The American Academy of Pediatrics (AAP) defines ALTE (Acute Life Threatening Event), as an abrupt and unexpected event that includes manifestations of apnea along with changes in skin color and muscle tone, where the observer believes that the child has died. The AAP has recently proposed replacing the term ALTE with Brief Resolved Unexplained Events (BRUE). The new concept makes it possible to categorize brief, resolved and unexplained events, to better optimize the health resource, through objectifying the event and delivering management strategies by categorizing the risk. Objective: To describe the clinical characteristics and lethality of patients younger than 12 months who consult for BRUE in a referral hospital. Materials and methods: Descriptive cross-sectional study with revision of the file of 46 patients from the Infant and Nutrition Unit of the Dr. Luis Calvo Mackenna Hospital, with a diagnosis of BRUE, between January and December 2017. Results: Of the total number of patients with BRUE, 45% were men and 55% women. The average age was 1.37 + 0.51 months. An etiology was demonstrated in 70%, of these 31% with gastroesophageal reflux disease (GERD), this being the most frequent cause, followed by 19% with acute respiratory infections (ARI) and 9% with neurological causes. In 30% they were idiopathic causes. Conclusion: In our study, the most frequent causes of BRUE were GERD and respiratory infections. During the study period, no patient studied died, so we found no relationship between apnea in the infant and sudden death syndrome.

Achondroplasia is associated with increased occurrence of apparent life-threatening events.

AIM: To assess the clinical picture underlying apparent life-threatening events (ALTEs) occurring in infants with achondroplasia and provide guidance for evaluation after an event. METHODS: A population of 477 individuals with achondroplasia was retrospectively reviewed, and information regarding possible ALTEs was recorded in a REDCap database. RESULTS: ALTEs occurred in the first year of life in 18 of 477 individuals (3.8%). Most (14/18, 78%) occurred in the first 6 months of life and presented as episodes of apnoea and/or seizures. Of affected infants, 8/18 (44%) had more than one episode. Many of the initial ALTEs arose while infants were in car seats (11/18, 61%). Assessment following ALTEs most often demonstrated either craniocervical junction concerns and/or seizures, with 12/18 (67%) patients undergoing cervicomedullary decompression and 5/18 (28%) starting on anti-epileptic medications after the event. CONCLUSION: Although this study is limited in size and was retrospective, it shows that infants with achondroplasia appear to be at high risk for ALTEs. Evaluation after an event should include neuroimaging of the foramen magnum, inpatient hospital observation including respiratory monitoring and electroencephalography, and a car seat challenge.

Aplicación de una nueva terminología "BRUE: Eventos breves, resueltos e inexplicados": definiciones y recomendaciones / Application of a new terminology "BRUE: Brief, resolved and unexplained events": definitions and recommendations

Resumen: Hace tres décadas se propuso el término Apparent Life-Threatening Events (ALTE), siendo incorpo rado paulatinamente en el enfrentamiento clínico de estos pacientes; permitiendo determinar riesgos, atribuir causas y realizar tratamientos específicos. Sin embargo, llevó a realizar estudios y hospitalizaciones en muchas instancias considerados innecesarios, generando un aumento de los costos sanitarios. Por estos motivos nace el concepto de Brief Resolved Unexplained Events (BRUE), que pretende disminuir la subjetividad del evento y focalizar una estrategia de manejo según determina ción del riesgo. En el siguiente artículo se analizan diferencias entre ALTE y BRUE según consensos internacionales y chilenos, profundizando en el enfrentamiento e incorporando consideraciones de relevancia para la práctica clínica cotidiana de lactantes que presentan un BRUE.

Abstract: Three decades ago, the term Apparent Life-Threatening Events (ALTE) was proposed and was gra dually incorporated into the clinical approach of these patients, allowing to determine risks, attribute causes, and perform specific treatments. However, this led to studies and hospitalizations considered unnecessary in many cases, increasing health costs. For this reason, the concept of Brief Resolved Unexplained Events (BRUE) was created, in order to reduce the subjectivity of the event and focus a management strategy according to the risk determination. This article analyzes the differences bet ween ALTE and BRUE according to international and Chilean consensus, deepening the approach and incorporating relevant considerations for the daily clinical practice with infants who present a BRUE.

Efecto de un enfoque estandarizado para el manejo de lactantes hospitalizados por eventos aparentemente letales / Effect of a standardized approach on infants hospitalized for apparent life threatening events

Introducción. Los eventos aparentemente letales (Apparent Life-Threatening Event, ALTE) son causa frecuente de hospitalización en lactantes. Hay poca información sobre el enfoque estandarizado para establecer su etiología, a pesar de que un diagnóstico causal correcto puede afectar la evolución clínica, la duración de la hospitalización y los recursos sanitarios. Objetivo. Comparar los efectos del enfoque diagnóstico estandarizado en lactantes hospitalizados por este tipo de eventos. Materiales y métodos. Se hizo un estudio retrospectivo de cohorte con base en los datos recolectados de las historias clínicas de lactantes hospitalizados por esta causa en el servicio de pediatría entre el 2002 y el 2009. Se analizaron dos cohortes de pacientes agrupados según su manejo: la cohorte 1, con guías clínicas, y la cohorte 2, con guías clínicas, protocolo de estudio y seguimiento ambulatorio. Se compararon los grupos en cuanto a la etiología, el tiempo de hospitalización y la tasa de nuevas hospitalizaciones. Resultados. De los 255 lactantes hospitalizados por eventos aparentemente letales, el 57,6 % integró la cohorte 1 y, el 42,3 %, la cohorte 2. No se observaron diferencias en cuanto a la edad y el sexo. En la cohorte 2 se observó un mayor porcentaje de causas atribuidas (63,9 Vs. 87,0; p<0,0001), y un menor tiempo de hospitalización (8,0 Vs. 5,0 días; p=0,0001). No hubo diferencias en cuanto a nuevas hospitalizaciones (10,5 Vs. 8,3 días; p=0,7435). Conclusiones. El enfoque del manejo de lactantes afectados por eventos aparente letales basado en protocolos, se asoció con un mayor porcentaje de reconocimiento de las causas atribuidas y con un menor período de hospitalización. A partir de estos resultados es posible sugerir la implementación de este tipo de estandarización para el manejo de dichos pacientes.

Introduction: An apparent life-threatening event (ALTE) is a frequent cause of hospitalization in infants. However, there is little evidence about the existence of a standardized approach to discover the main etiology, although a correct causal diagnosis can affect clinical evolution, hospital stay, and health resources. Objective: To determine the effects of a standardized diagnostic approach in infants admitted with ALTE. Materials and methods: We conducted a retrospective cohort study with the data collected from clinical records of infants hospitalized for ALTE in the pediatric unit between 2002 and 2009. Two cohorts of patients were analyzed according to the procedures defined for these cases: Cohort 1 with clinical guidelines and cohort 2 with clinical guidelines, study protocol, and outpatient follow-up. Etiological causes, hospitalization periods and readmission rates were compared between both cohorts. Results: Of the 255 infants hospitalized for ALTE, 57.6% corresponded to cohort 1 and 42.3% to cohort 2. No differences were observed in age and gender between groups. The highest percentage of attributed causes (63.9 vs 87.0%; p<0.0001) and a shorter period of hospitalization (8.0 vs 5.0 days; p=0, 0001) were observed in cohort 2. No differences in hospital readmission were observed (10.5 vs 8.3 days; p=0.7435). Conclusions: The protocol-based approach for infants with EAL was associated with a higher percentage of recognition of attributed causes and a shorter hospitalization period. Therefore, our results allow recommending this type of standardization for the management of these patients.

Hospitalizaciones por ALTE en el Centro Hospitalario Pereira Rossell: (1/12/2010 - 1/12/2011) / Hospitalizations due to ALTE in the Pereira Rossell Hospital Center: 1/12/2010 - 1/12/2011

Introducción: el ALTE (evento de aparente amenaza a la vida) genera ansiedad y preocupación en la familia y representa un desafío para el personal de salud. En Uruguay no se dispone de datos para evaluar la magnitud del problema. Objetivo: describir la prevalencia y características de los lactantes hospitalizados por ALTE en el Departamento de Pediatría del Centro Hospitalario Pereira Rossell (CHPR). Material y método: diseño descriptivo, retrospectivo. Período: 1°/12/2010 - 1°/12/2011. Criterios de inclusión: menores de un año hospitalizados en salas de cuidados moderados con diagnóstico de ALTE. Variables: edad, sexo, factores de riesgo (FR) para síndrome de muerte súbita (SMSL), estudios e interconsultas realizadas, evolución, duración de la estadía hospitalaria y diagnóstico al egreso. Fuente de datos: historias clínicas. Análisis: EpiInfo versión 2002. Resultados: fueron hospitalizados 2.695 menores de un año: 71 (2,6%) con ALTE. Tasa de hospitalización 26,3/1.000 (IC95% 20,2-32,3); 52,1% varones; 62% menores de dos meses. Se solicitaron estudios paraclínicos en 62 de los 71 niños con ALTE: en 8/8 c/ALTE mayor, en 46/50 con ALTE menor con FR, 8/13 con ALTE menor s/FR. El diagnóstico al egreso fue ALTE idiopático 36/71 (50,7%) y secundario 35/71 (49,3%). Se identificó causa digestiva en 21/35, respiratoria en 12/35 y neurológica en 2/35. La media de la estadía hospitalaria fue de 7 días (rango 1-51 días). Cuatro niños fueron hospitalizados en centro de tratamiento intensivo (CTI). Ninguno requirió soporte ventilatorio ni falleció. Conclusión: en el CHPR la mayoría de las hospitalizaciones por ALTE ocurren en niños menores de dos meses de edad que consultan por cambios de coloración y presentan factores de riesgo para SMSL. Se destaca la falta de criterios uniformes en el abordaje de estos niños y el bajo rendimiento de las pruebas diagnósticas.

Introduction: ALTE creates anxiety and results in families being worried families, constituting a challenge for health professionals. However, there are no data available in Uruguay to assess how big the problem is.Objective: To describe prevalence and characteristics infants hospitalized due to ALTE in the Pediatrics Unit at the Pereira Rossell Hospital Center.Method: Design: descriptive, retrospective study. Period: December 1, 2010 through December 1, 2011. Criteria for inclusion: hospitalized infants younger that one year old, who had a diagnosis of ALTE. Variables: age, sex, risk factors for sudden infant death syndrome, studies and interconsultations, evolution, length of hospitalization and diagnosis on discharge. Source of data: clinical records. Analysis: Epiinfo 2002 version.Results: Two thousand six hundred and ninety five children younger than 1 year old: 71 (2.6 %) had ALTE. Hospitalization rate: 26.3/1000 (IC95% 20.2-32-3); 52% were boys; 62% < 2 months. Paraclinical studies were requested in 62 out of 71 children with ALTE: in 8/8 with high ALTE, in 46/50 with lower ALTE with risk factors, 8/13 with lower ALTE without risk factors. Diagnosis on discharge was idiopathic ALTE in 36/71 (50.7%) and secondary ALTE in 35/71 (49.3%). Digestive causes were identifies in 21 out of 35 cases, respiratory in 12 out of 35 cases and neurological in 2 out of 35 cases. Average hospital stay was 7 days (1-51 days range). Four children were admitted to the ICU. None of them required mechanic ventilation and none of them died.Conclusion: Most hospitalizations due to ALTE occur in infants younger than 2 months old at the CHPR, and they consult for changes in color, evidencing risk factors for sudden infant death syndrome. The present study points out there are no uniform criteria to treat these children and diagnostic testing had a low yield.

Introdução: O ALTE gera ansiedade e preocupação na família e é um desafio para a equipe de saúde. No Uruguai não se dispõe de dados para avaliar a magnitude do problema.Objetivo: Descrever a prevalência e as características dos lactentes internados por ALTE no Departamento de Pediatria do CHPR.Material e método: Tipo de estudo: descritivo, retrospectivo. Período: 1°/12/2010 - 1°/12/2011. Critérios de inclusão: < 1 ano internados em salas de cuidados moderados com diagnóstico de ALTE. Variáveis: idade, sexo, fatores de risco (FR) para síndrome de morte súbita (SMSL), estudos e interconsultas realizadas, evolução, duração da internação hospitalar e diagnostico na alta. Fonte de dados: prontuários médicos. Análise: Epiinfo versão 2002.Resultados: Foram hospitalizados 2695 <1 ano: 71 (2.6%) com ALTE. Taxa de hospitalização 26.3/1000 (IC95%20.2-32.3). 52.1% de sexo masculino; 62% < 2 meses. Foram solicitados exames de rotina de 62 das 71 crianças com ALTE: em 8/8 com ALTE maior, em 46/50 com ALTE menor com FR, 8/13 com ALTE menor sem FR. O diagnóstico na alta foi ALTE idiopático 36/71(50,7%) e secundário 35/71(49,3%). Identificou-se causa digestiva em 21/35, respiratória em 12/35 e neurológica em 2/35. A média da permanência no hospital foi de 7 dias (intervalo 1-51 dias). Foram internadas na UTI quatro crianças. Nenhuma necessitou suporte ventilatório nem faleceu.Conclusão: No CHPR a maioria das internações por ALTE são de crianças com menos de 2 meses de idade que consultam por mudanças na coloração e apresentam fatores de risco para SMSL. Destaca-se a falta de critérios uniformes na abordagem destas crianças e o baixo rendimento dos exames diagnósticos.

Consenso sobre el manejo de eventos de aparente amenaza a la vida del lactante (ALTE): comisión de sueño, sociedad chilena de neumología pediátrica 2013 / Consensus on evaluation and management of apparent life-threatening events in infancy (ALTE)

Un Evento de Aparente Amenaza de la Vida o ALTE (del inglés: Apparent Life Threatening Event) corresponde a un episodio agudo que ante los ojos del observador pone en riesgo la vida de un lactante menor de 1 año. Debe presentar la combinación de 2 o más de los criterios siguientes: apnea / cambio de color / alteración del tono / atoro e implicar la necesidad de algún tipo de maniobras para reanimar. En el presente consenso sobre el manejo de un ALTE se revisaron la evidencia internacional y nacional respecto al enfoque diagnóstico, estudio etiológico, criterios y duración de hospitalización y las indicaciones de monitorización domiciliaria.

Apparent life threatening events are defined as an acute episode in which the observer fears an infant < 1 year may die. ALTE is characterized by some combination of apnea, color or muscle tone change, chocking and has to be followed by cardiorespiratory reanimation. The present consensus paper reviews international and national evidence concerning diagnosis, etiologies, hospitalization criteria and indications for home monitoring.

Caracterización actualizada del síndrome de ALTE / Upadated characterization of ALTE syndrome

El ALTE no es una enfermedad específica en sí misma, sino una forma de presentación clínica de diversas enfermedades, su incidencia se estima en 6 por 1 000 en aquellos lactantes nacidos a término, y asciende a un 86 por 1 000 en los nacidos pretérmino. Su etiología es multifactorial, el diagnóstico es difícil y precisa de experiencia, y la conducta depende de las causas que lo originen. Esta afección poco reconocida en la práctica médica actual, genera una enorme ansiedad en la familia, y constituye un desafío en cuanto al diagnóstico, manejo y consejos por parte del pediatra

Apparent life-threatening event (ALTE) is not a specific disease, rather a form of clinical presentation of several diseases. Its incidence rate is estimated to be 6 per 1000 in the term infants and 86 per 1000 in preterm infants. The etiology of the event is multifactoral, the diagnosis is difficult and requires experience, and the behavior to be adopted depends on the causes that bring it about. This poorly recognized illness in the present medical practice gives rise to a lot of anxiety for the family and represents a true challenge in terms of diagnosis, management and counseling by the pediatrician

Aparente amenaza para la vida por el síndrome de QT prolongado / An apparent life threatening secondary to long Qt syndrome

Se presenta el caso de un lactante con un episodio de pérdida de conocimiento, en quien se diagnosticó fibrilación ventricular. Se realizó desfibrilación externa con éxito, permitiendo luego arribar al diagnóstico etiológico de síndrome de QT prolongado, constituyendo un ejemplo documentado de esta entidad como causa del síndrome de muerte súbita del lactante.

We report the case of an infant with an episode of loss of consciousness, in whom ventricular fibrillation was diagnosed. He was successfully defibrillated and long QT syndrome was diagnosed as his baseline disease. This case constitutes a documented example of this entity as a cause of the sudden infant death syndrome.

Eventos adversos graves de la transición conjunta en el recién nacido: caso clínico / Serious adverse events in the transition period of the newborn

Introducción: El contacto piel a piel postparto es importante pues favorece la lactancia, la adaptación del recién nacido y la relación entre la madre y el hijo. La observación clínica de este período de transición es fundamental. Caso clínico: Se presentan dos casos de eventos adversos serios producidos en el período piel a piel postparto, sin que se identifiquen patologías que expliquen el evento. Uno de los casos presenta secuelas neurológicas. En ambos casos estaban con observación de los padres. Discusión: La literatura ha reportado estos casos durante período neonatal, generalmente precoces, en madres primíparas, frecuentemente en posición prono. Proveer contacto precoz debe considerar un ambiente terapéutico y adecuada observación clínica, sin delegar esta responsabilidad en los padres.

Introduction: The postpartum skin to skin contact (SSC) facilitates breastfeeding, newborn adaptation and the relationship between mother and child. Clinical observation of this transition period is essential. Case study: Two cases of serious adverse events produced in the postpartum SSC period are presented without identified pathology to explain the event. One case presented neurologic sequelae. Both cases were under the parents' watch. Discussion: The literature has reported these cases during neonatal period, usually in early stage, in primiparous mothers, and often in prone position. Providing early contact between the two of them should consider a therapeutic environment and adequate clinical observation, without delegating this responsibility to the parents.

Evento com aparente risco de morte recorrente como manifestação inicial de síndrome miastênica congênita / Recurrent apparent life-threatening event as the first manifestation of congenital myasthenia / Evento con aparente riesgo de muerte recurrente como manifestación inicial de síndrome miasténico congénito

OBJETIVO: Alertar os pediatras sobre a necessidade de investigar criteriosamente a etiologia de eventos com aparente risco de morte recorrente. Não foram encontrados relatos associando tais eventos à miastenia congênita. DESCRIÇÃO DO CASO: Lactente de sete meses apresentando história de eventos com aparente risco de morte recorrente foi internado para investigação. Durante a internação, apresentou cianose e dispneia progressiva, com necessidade de ventilação mecânica por três dias. Após a melhora clínica, e tendo sido descartadas as hipóteses de doença do refluxo gastroesofágico e aspiração pulmonar como desencadeantes, notou-se ptose palpebral bilateral, hipotonia apendicular e choro fraco, que conduziram à suspeita clínica de miastenia congênita. Após confirmação do diagnóstico, foi mantido tratamento ambulatorial com piridostigmina, com recuperação nutricional e neurológica, sem novos eventos com aparente risco de morte nos três anos seguintes. COMENTÁRIOS: A investigação minuciosa das causas de eventos com aparente risco de morte pode levar a diagnósticos menos frequentes que exigem tratamento específico, como a miastenia congênita.

OBJECTIVE: To alert pediatricians about the importance of a careful investigation on recurrent apparent life-threatening events. Reports of the association of these events with congenital myasthenic syndromes were not found. CASE DESCRIPTION: A seven-month-old infant with recurrent apparent life-threatening events was admitted for investigation. During hospital stay, she presented cyanosis and respiratory failure, requiring mechanical ventilation for three days. After clinical improvement, hypotheses of gastroesophageal reflux and pulmonary aspiration were ruled out. The presence of eyelid ptosis, general hypotonia and weak crying led to the suspicion of congenital myasthenia, which was confirmed. Treatment with oral piridostigmine led to neurological and nutritional normalization, without any other apparent life-threatening event during the next three years. COMMENTS: The careful etiological investigation of apparent life-threatening events may lead to rare diagnosis that requires specific treatments, such as congenital myasthenia.

OBJETIVO: Alertar a los pediatras sobre la necesidad de investigar criteriosamente la etiología de eventos con aparente riesgo de muerte recurrente. No se encontraron relatos asociando tales eventos a la miastenia congénita. DESCRIPCIÓN DEL CASO: Lactante de siete meses presentando historia de eventos con aparente riesgo de muerte recurrente fue internado para investigación. Durante la internación, presentó cianosis y disnea progresiva, con necesidad de ventilación mecánica por tres días. Después de la mejora clínica, y habiendo sido rechazadas las hipótesis de enfermedad del reflujo gastroesofágico y aspiración pulmonar como desencadenantes, se notó ptosis palpebral bilateral, hipotonía apendicular y lloro débil, que condujeron a la sospecha clínica de miastenia congénita. Después de la confirmación del diagnóstico, se mantuvo el tratamiento ambulatorial con piridostigmina, con recuperación nutricional y neurológica, sin nuevos eventos con aparente riesgo de muerte en los tres años siguientes. COMENTARIOS: La investigación minuciosa de las causas de eventos con aparente riesgo de muerte puede llevar a diagnósticos menos frecuentes que exigen tratamiento específico, como la miastenia congénita.

Apparent life-threatening events: an update.

Based on strong research evidence, the most common causes of apparent life-threatening events (ALTEs) are gastroesophageal reflux, lower respiratory tract infection, and seizure. • The minimum initial diagnostic panel for ALTE should include complete blood cell (CBC) count with differential; blood levels of C-reactive protein,glucose, sodium, potassium, urea, calcium,magnesium, ammonia, lactate, and pyruvate; arterial blood gas determination, urinalysis, and toxicology screen; electrocardiography; and assessments for Bordetella pertussis and respiratory syncytial virus in season. • Other testing should be done based on the infant's clinical presentation and clinician's degree of suspicion.• Most infants should be hospitalized for cardiorespiratory monitoring for 23 hours after an ALTE. • There is strong evidence that newborns are at higher risk of ALTE and sudden infant death syndrome (SIDS)within the first 24 hours after birth and therefore should be frequently monitored as much as possible while room sharing with their mothers. • Evidence suggests that maternal smoking may place an infant for higher risk of SIDS after an ALTE.

Apneas e infecciones en lactantes / Apnea and infections in infants

Infections are a frequent cause of apnea in infants, involving both respiratory and extrarrespiratory systems. In the first group we find upper respiratory infections and lower respiratory infections caused by virus or bacteria such as Respiratory Syncytial Virus, Parainfluenza and Bordetella pertussis; in the second group urinary tract infections and severe infections such as meningitis and sepsis are of importance. In this article we analyze different causes of infections attributed to apnea, taking into account existing literature at the time.

Las infecciones son una frecuente causa de apneas en lactantes, pudiendo involucrar tanto el sistema respiratorio como extrarrespiratorio. En el primero encontramos las infecciones respiratorias altas y/o bajas producidas tanto por virus como bacterias, donde destacan Virus Respiratorio Sincicial, Parainfluenza y Bordetella Pertussis; en el segundo grupo son de importancia la infección urinaria e infecciones graves como meningitis y sepsis. En este artículo se analizan estas distintas causas infecciosas atribuidas a eventos de apneas en lactantes, en consideración a la literatura actualmente existente.

Usefulness of airway evaluation in infants initially seen with an apparent life-threatening event.

OBJECTIVES: To determine how often the pediatric otolaryngology service is involved in the initial care of infants with an apparent life-threatening event (ALTE), to assess the usefulness of bronchoscopy and laryngoscopy in diagnosing the underlying etiology, and to describe the long-term airway outcomes and whether these patients were seen by the pediatric otolaryngology service over a 5-year follow-up period. DESIGN: Retrospective observational study. SETTING: Tertiary children's hospital affiliated with a university hospital. PATIENTS: Screened were 187 903 patient visits for infants younger than 12 months. A total of 1148 infants with an ALTE were identified, 471 of whom met study inclusion criteria. To identify the study population, these infants were cross-referenced against a database of 5156 patients who underwent airway evaluation by the pediatric otolaryngology service. MAIN OUTCOME MEASURES: Airway evaluation with or without intervention. RESULTS: Four hundred seventy-one infants with an ALTE met study inclusion criteria, 9 of whom subsequently underwent airway evaluation via bronchoscopy, laryngoscopy, or both. Three were referred during their initial ALTE admission, and 6 were seen later in childhood. Five of 9 patients had normal findings, 3 patients had laryngomalacia (including 2 with laryngeal edema), and 1 patient had adenotonsillar hypertrophy. Interventions consisted of 2 supraglottoplasties and 1 adenotonsillectomy. CONCLUSIONS: Among well-appearing infants hospitalized with an ALTE, 98.1% (462 of 471) did not undergo subsequent airway evaluation, and only 0.6% (3 of 471) ultimately required pediatric otolaryngologic surgical intervention during 5 years after the event. This study shows that otolaryngologists are not frequently consulted for well-appearing infants with an ALTE and that airway abnormalities are rare.

Fatores associados ao óbito em lactentes após eventos com aparente risco de morte (apparent life-threatening event, ALTE) / Factors associated with infant death after apparent life-threatening event (ALTE)

OBJETIVO: Identificar, na admissão dos lactentes com após eventos com aparente risco de morte (apparent life-threatening event, ALTE), fatores que possam indicar maior risco de evolução para o óbito. MÉTODOS: Estudo transversal retrospectivo, descritivo e analítico com lactentes menores de 12 meses, com evento súbito de cianose, palidez, hipotonia e/ou apneia, atendidos na unidade de emergência de hospital universitário de nível terciário. Para avaliação da associação, determinaram-se os valores de odds ratio bruto e ajustado por regressão logística (método stepwise forward Wald). RESULTADOS: Foram avaliados 145 pacientes com idade média de 105 dias (mediana = 65 dias). Onze (7,6 por cento) evoluíram para óbito, com idade média de 189 dias (mediana = 218 dias), enquanto que a idade média dos sobreviventes foi de 98 dias (mediana = 62 dias) (p = 0,003). Atividades que precederam o evento, antecedente de prematuridade e número de episódios não apresentaram associação com o óbito. Apresentou relação significativa o relato de palidez pelos observadores. Entre os 11 lactentes, 3 apresentaram melhora imediata e espontânea; já 8 pacientes [27,6 por cento; p < 0,001; OR = 14,3 (IC95 por cento 3,51-58,3)] não tiveram melhora espontânea. Os diagnósticos de doença do trato respiratório e do sistema cardiocirculatório também foram significantes. Na análise multivariada, mostraram significância estatística: não melhora imediata e espontânea [p = 0,015; OR = 6,06 (IC95 por cento 1,02-35,94)] e diagnóstico de doença do sistema cardiocirculatório [p = 0,047; OR = 164,27 (IC95 por cento 7,34-3.673,78)]. CONCLUSÃO: Os lactentes que apresentaram ALTE tiveram maior risco de óbito quando presentes na faixa etária acima dos 6 meses e quando os eventos tiveram duração prolongada, principalmente quando ocorreram como manifestação de doenças do sistema cardiocirculatório.

OBJECTIVE: To detect factors associated with greater risk of death in infants after an apparent life-threatening event (ALTE). METHODS: This cross-sectional, retrospective, descriptive and analytic study evaluated infants younger than 12 months who had a sudden event of cyanosis, pallor, hypotonia or apnea and were seen in the emergency department of a tertiary university hospital. Forward stepwise logistic regression (Wald) was used to calculate and adjust odds ratios to evaluate associations. RESULTS: Mean age of the 145 patients included in the study was 105 days (median = 65 days). Eleven (7.6 percent) died, and their mean age was 189 days (median = 218 days). Mean age of survivors was 98 days (median = 62 days) (p = 0.003). Activity before the event, prematurity and number of events were not associated with death. A significant association was found with pallor. Of the 11 infants, 3 had spontaneous resolution of ALTE, whereas 8 patients [27.6 percent; p < 0.001; OR = 14.3 (95 percentCI 3.51-58.3)] did not. The associations with respiratory or cardiovascular disease were also significant. In multivariate analysis, immediate spontaneous resolution [p = 0.015; OR = 6.06 (95 percentCI 1.02-35.94)] and diagnosis of cardiovascular disease [p = 0.047; OR = 164.27 (95 percentCI 7.34-3.673.78)] remained statistically significant. CONCLUSION: Infants who experienced an ALTE had a higher risk of subsequent death when their age was greater than 6 months and the event had a long duration, particularly when ALTE was associated with cardiovascular disease.

Consenso para o manejo e seguimento de pacientes com episódios de possível ameaça a vida (ALTE) e abordagem do diagnóstico diferencial de ALTE com primeira crise convulsiva / Consensus document for the clinical evaluation and follow up of infants with an apparent life threatening event (ALTE) and its differential diagnosis with first seizure

OBJETIVO: Este estudo teve como objetivo a elaboração de guia para manejo e seguimento de crianças com episódios de possível ameaça a vida (ALTE) com enfoque especial ao diagnóstico diferencial deste evento com primeiro episódio de crise convulsiva. MÉTODOS: Através de revisão da literatura foi elaborado um consenso, entre os membros do comitê de Síndrome da Morte Súbita do Lactente (SMSL) da Associação Latinoamericana de Pediatria (ALAPE), para orientação quanto ao manejo e investigação etiológica de pacientes com ALTE. RESULTADOS: A proposta de sistematização da investigação destes pacientes inicia definindo a gravidade do evento e estabelecendo a necessidade de internação ou seguimento ambulatorial. A pesquisa da etiologia deve ser realizada gradualmente sendo dividida em exames iniciais e exames específicos, que são aprofundados de acordo com as características clínicas do caso em questão. O manejo após alta hospitalar e a indicação de monitorização domiciliar devem ser individualizados e avaliados caso a caso. O ALTE pode ser a primeira manifestação de uma crise epiléptica ,entretanto, este diagnóstico algumas vezes é tardio, quando não é disponível EEG ictal. O EEG interictal, nestes casos, geralmente é normal e o refluxo gastroesofágico, distúrbio muito prevalente na infância, pode confundir o diagnóstico da manifestação epiléptica. CONCLUSÃO: O ALTE não deve ser considerado um diagnóstico etiológico, mas conjunto de sinais percebidos pelo observador que deve ser amplamente investigado. Apesar de pouco freqüente, a apnéia pode ser a única manifestação ictal de uma crise parcial. Esta possibilidade deve ser lembrada e excluída no diagnóstico diferencial da etiologia de ALTE. As orientações sugeridas neste artigo assim como o fluxograma de investigação apresentado podem auxiliar no manejo e seguimento dos pacientes com ALTE assim como resultar em redução do tempo e custo de internação destes pacientes.

OBJECTIVE: The aim of this study was to propose guidelines to clinical investigation of patients with an apparent life threatening event (ALTE) with focus on the differential diagnosis with first seizure. METHODS: Based on literature review and a consensus meeting, members of the Sudden Infant Death Committee (SIDS) of the Latin American Society of Pediatrics (ALAPE) elaborated guidelines to help pediatricians evaluate children with ALTE. RESULTS: The proposal presented starts evaluating the gravity of the event and the consequent choice for admission or outpatient follow up. The search for etiology should be gradual starting with low complexity exams. After discharge follow up should be individualized as the choice of home monitoring. An ALTE may be the first manifestation of an epileptic seizure, however, the diagnosis is sometimes delayed when an ictal EEG is not available, because interictal EEGs are often normal and gastroesophageal reflux, a disorder very prevalent in early childhood, may mislead the diagnosis of the epileptic manifestation. CONCLUSIONS: ALTE cannot be considered an etiological diagnosis, moreover, it is a group of signs and symptoms that should be thoroughly investigated. Although not often, an apneic spell may be the only manifestation of partial seizures. This possibility should be reminded and ruled out in the etiological diagnosis of children with ALTE. The information provided in this guideline may help in the evaluation and follow up of ALTE patients, including a reduction on time and cost of hospitalization.
