Hypoxic Ischemic Encephalopathy in Units Reporting to the Ibero-American Society of Neonatology Network: Prevalence and Mortality.

INTRODUCTION: Hypoxic ischemic encephalopathy is a neurological condition occurring immediately after birth following a perinatal asphytic episode. Therapeutic hypothermia is a safe and effective intervention to reduce mortality and major disability in survivors. In Latin America, perinatal asphyxia is a major problem, but no data are available characterizing its current situation in the region or the impact of hypoxic ischemic encephalopathy on its management. OBJECTIVE: Understand the prevalence, mortality and use of therapeutic hypothermia in newborns at ≥36 weeks gestational age with hypoxic ischemic encephalopathy admitted to neonatal units reporting to the Ibero-American Society of Neonatology Network. METHODS: The Ibero-American Society of Neonatology Network groups various neonatology centers in Latin America that share information and collaborate on research and medical care. We evaluated data on newborns with ≥36 weeks gestational age reported during 2019. Each unit received a guide with definitions and questions based on the Society's 7th Clinical Consensus. Evaluated were encephalopathy frequency and severity, Apgar score, need for resuscitation at birth, use of therapeutic hypothermia and clinical evolution at discharge. Our analysis includes descriptive statistics and comparisons made using the chi-square test. RESULTS: We examined reports of 2876 newborns from 33 units and 6 countries. In 2849 newborns with available data, hypoxic encephalopathy prevalence was 5.1% (146 newborns): 27 (19%) mild, 36 (25%) moderate, 43 (29%) severe, and 40 (27%) of unknown intensity. In those with moderate and severe encephalopathy, frequencies of Apgar scores ≤3 at the first minute (p = 0.001), Apgar scores ≤3 at the fifth minute (p ⟨0.001) and advanced resuscitation (p = 0.007) were higher. Therapeutic hypothermia was performed in only 13% of newborns (19). Neonatal mortality from encephalopathy was 42% (61). CONCLUSIONS: Hypoxic ischemic encephalopathy is a neonatal condition that results in high mortality and severe neurological sequelae. In this study, the overall prevalence was 5.1% with a mortality rate of 42%. Although encephalopathy was moderate or severe in 54% of reported cases, treatment with hypothermia was not performed in 87% of newborns. These data reflect a regional situation that requires urgent action.

Factores asociados con bajo puntaje de Apgar en la maternidad del Centro Hospitalario Pereira Rossell / Factors associated with low Apgar score in the maternity of Pereira Rossell Hospital / Fatores associados com baixa pontuação de Apgar na maternidade do Centro Hospitalar Pereira Rossell

Introducción: La depresión neonatal es una de las causas más frecuentes de ingreso de recién nacidos a unidades especializadas de atención neonatal. La asfixia perinatal es una de las causas de bajo puntaje de Apgar, siendo uno de los criterios clínicos para su diagnóstico. Los principales factores de riesgo vinculados con bajos puntajes de Apgar pueden ser maternos (edad, patologías obstétricas, nivel socioeconómico, adicciones, etc.), del trabajo de parto y parto o, alteraciones fetales. Objetivos: Determinar los factores perinatales asociados a la baja puntuación de Apgar a los 5 minutos. Diseño: Estudio retrospectivo de casos y controles en los años 2015 y 2016. Institución: Hospital de la Mujer, Centro Hospitalario Pereira Rossell, Montevideo, Uruguay. Participantes: Se incluyeron todos los recién nacidos término con Apgar a los 5 minutos menor o igual a 5. Resultados: Hubo un total de 12.528 nacimientos de recién nacidos vivos de término en el HM. 34 casos de recién nacidos con Apgar a los 5 minutos menor o igual a 5. Esto corresponde al 0,27% de la población. No se identificaron diferencias estadísticamente significativas en cuanto a los principales factores asociados a asfixia perinatal. Conclusiones: En el análisis de esta población, la mayoría de los factores analizados no se asocia con los casos de Apgar a los 5 minutos menor o igual a 5 (depresión neonatal moderada-severa), por lo que la mayoría de estos casos pueden no ser evitables.

Introduction: Neonatal depression is one of the most frequent causes of admission of newborns to specialized units of neonatal care. Perinatal asphyxia is one of the causes of low Apgar score, and it is one of the clinical criteria for its diagnosis. Main risk factors associated with low Apgar scores can be maternal (age, obstetric pathologies, socioeconomic level, addictions, etc.), of labor and delivery or, fetal alterations. Objective: To determine the perinatal factors associated with the low Apgar score at 5 minutes. Design: Retrospective study of cases and controls in 2015 and 2016. Institution: Maternity, Women Hospital, Centro Hospitalario Pereira Rossell, Montevideo, Uruguay. Patients: We included all term newborns with Apgar at 5 minutes less than or equal to 5. Results: There was a total of 12,528 births of term full-term newborns in the HM. 34 cases of newborns with Apgar at 5 minutes less than or equal to 5. This corresponds to 0.27% of the population. No statistically significant differences were identified regarding the main factors associated with perinatal asphyxia. Conclusions: In the analysis of this population, most of the analyzed factors are not associated with cases of Apgar at 5 minutes less than or equal to 5 (moderate-severe neonatal depression), so that most of these cases may not be avoidable.

Não foram identificadas diferenças estatisticamente significantes quanto aos principais fatores associados à asfixia perinatal. Conclusões: Na análise dessa população, a maioria dos fatores analisados não está associada aos casos de Apgar em 5 minutos menor ou igual a 5 (depressão neonatal moderada a grave), de modo que a maioria desses casos pode não ser evitável.

[Quality care indicators for neonates with selected pathologies: pilot study.] / Indicadores de calidad de la atención a neonatos con patologías seleccionadas: estudio piloto.

OBJECTIVE: Develop and pilot indicators of quality of care to neonates with relevant conditions in Mexico (prematurity, neonatal sepsis, perinatal asphyxia, and intrauterine hypoxia). MATERIALS AND METHODS: Own indicators were built based on key recommendations of national clinical practice guidelines and indicators found in international repositories. With previous search, selection and prioritization, the indicators were piloted within two hospitals. The feasibility of measuring, (kappa index) reliability and usefulness was analyzed to detect quality problems. RESULTS: 23 indicators were selected and piloted, 12 are compounds, of the total, nine were feasible and reliable. The quality of the hospital's information was diverse and often poor, limiting both the feasibility and the reliability of the indicators. Improvement opportunities were identified thorough the compliance levels. CONCLUSIONS: A set of nine indicators valid, reliable, feasible and useful indicators is proposed in order to monitor the quality of care of pathological neonates.

Factores asociados a epilepsia en niños en México: un estudio caso-control / Factors associated with epilepsy in children in Mexico: A case-control study

Resumen: Introducción: La epilepsia es la enfermedad neurológica crónica más común en el mundo. En México es considerada dentro de las principales enfermedades vinculadas a la mortalidad por enfermedades no infecciosas de la población infantil. El objetivo del estudio fue identificar los factores asociados a epilepsia en niños derechohabientes del Instituto Mexicano del Seguro Social (IMSS), en Acapulco, México. Métodos: Estudio de casos y controles realizado entre abril de 2010 y abril de 2011. Fueron seleccionados 118 casos de la consulta externa de neurología pediátrica, con criterios diagnósticos de epilepsia de acuerdo a la Liga Internacional Contra la Epilepsia, con máximo dos años de evolución. Los controles fueron seleccionados de las Unidades de Medicina Familiar de donde procedieron los casos. En una encuesta a las madres, se obtuvo información sobre antecedentes heredofamiliares, prenatales, perinatales y posnatales. El análisis bivariado y multivariado se realizó mediante el procedimiento de Mantel-Haenszel. Resultados: Tres factores estuvieron asociados con la epilepsia: el antecedente familiar de epilepsia en familiares de primer grado (Razón de Momios ajustada (RMa) 2.44, IC95% 1.18 - 5.03), la asfixia al nacimiento (RMa 2.20, IC95% 1.16-34.18) y la infección de la vía urinaria en la etapa prenatal (RMa, 1.80 IC95% 1.0 - 3.24). Conclusiones: La asfixia al nacimiento y el reporte de infecciones de vías urinarias durante la gestación fueron factores asociados a epilepsia independientemente del antecedente de epilepsia en familiares de primer grado.

Abstract: Background: Epilepsy is the most common chronic neurological disease in the world. In Mexico, epilepsy is among the diseases more related to mortality due to non-infectious diseases in children. The objective of the study was to identify the factors associated with epilepsy in children entitled to the Mexican Social Security Institute (IMSS), in Acapulco, Mexico. Methods: We carried out a case-control study from April 2010 to April 2011. We selected 118 cases from the database of outpatient pediatric neurology with epilepsy diagnostic with two year of evolution according to the International League Against Epilepsy criteria. We selected 118 controls from the same Medical Units where cases were detected. Data collected throughout an interview with the mothers included information on history of epilepsy among relatives, prenatal, perinatal and postnatal history. Bivariate and multivariate analysis was performed using Mantel-Haenszel process. Results: Multivariate analysis identified three factors associated with epilepsy: family history of epilepsy in first-degree relatives (adjusted Odds ratio (ORa) 2.44, 95%CI 1.18 -5.03), birth asphyxia (ORa 2.20, 95%CI 1.16-34.18), and urinary tract infection in the prenatal stage (ORa, 1.80, 95%CI 1.0 - 3.24). Conclusions: Preventing birth asphyxia and urinary tract infections during pregnancy reduces the risk of epilepsy regardless of the history of epilepsy in first-degree relatives.

ABSTRACT Objective To identify maternal, fetal and neonatal risk factors associated with perinatal hypoxia in neonates at Hospital Universitario Mayor Mederi (HUM Mederi) from 2007 to 2011. Methodology In the period 2007-2011, 8 837 children were born in HUM Mederi. Only the cases that presented with perinatal asphyxia (PA), according to the American Congress of Obstetricians and Gynecologists (ACOG), or another respiratory distress (RD) diagnosis were considered for this analysis, based on the computer records of the Neonatology Service in HUM Mederi. Maternal, fetal and neonatal risk factors were analyzed. Data were shown according to the number of newborns in each group and their percentage. Results The overall mortality rate was 10.7. The lowest values were found in 2010 and 2011 (3.3 and 1.8, respectively). Gestational diabetes, hypertension, chorioamnionitis and placenta previa were more frequent in the RD group, whereas hypoglycemia, sepsis, hypotonia and hypoactivity among neurological alterations were more common in the PA group. Correspondence between neurological alterations and Apgar Test was low in the cases diagnosed with PA. Conclusions The mortality rate was very low compared to regional and local levels, and more infants presented with moderate perinatal asphyxia. These results coincide with literature reports. The high number of preterm births with DR emphasizes the importance of controlling the implementation of actions to reduce the risk factors associated with this condition.

[Risk factors associated with the development of perinatal asphyxia in neonates at the Hospital Universitario del Valle, Cali, Colombia, 2010-2011].

INTRODUCTION: Perinatal asphyxia is one of the main causes of perinatal mortality and morbidity worldwide and it generates high costs for health systems; however, it has modifiable risk factors. OBJECTIVE: To identify the risk factors associated with the development of perinatal asphyxia in newborns at Hospital Universitario del Valle, Cali, Colombia. MATERIALS AND METHODS: Incident cases and concurrent controls were examined. Cases were defined as newborns with moderate to severe perinatal asphyxia who were older than or equal to 36 weeks of gestational age, needed advanced resuscitation and presented one of the following: early neurological disorders, multi-organ commitment or a sentinel event. The controls were newborns without asphyxia who were born one week apart from the case at the most and had a comparable gestational age. Patients with major congenital malformations and syndromes were excluded. RESULTS: Fifty-six cases and 168 controls were examined. Premature placental abruption (OR=41.09; 95%CI: 4.61-366.56), labor with a prolonged expulsive phase (OR=31.76; 95%CI: 8.33-121.19), lack of oxytocin use (OR=2.57; 95% CI: 1.08 - 6.13) and mothers without a partner (OR=2.56; 95% CI: 1.21-5.41) were risk factors for the development of perinatal asphyxia in the study population. Social difficulties were found in a greater proportion among the mothers of cases. CONCLUSIONS: Proper control and monitoring of labor, development of a thorough partograph, and active searches are recommended to ensure that all pregnant women have adequate prenatal care with the provision of social support to reduce the frequency and negative impact of perinatal asphyxia.

Resumen Introducción: La asfixia perinatal constituye una de las principales causas de morbilidad y mortalidad perinatal en el mundo, tiene factores de riesgo modificables y genera altos costos para los sistemas de salud. Objetivo: Determinar los factores de riesgo asociados al desarrollo de asfixia perinatal en recién nacidos en el Hospital Universitario del Valle, Cali, Colombia. Materiales y métodos: Se llevó a cabo un estudio de casos incidentes y controles concurrentes. Los casos se definieron como neonatos con asfixia perinatal moderada a grave, de edad de gestación mayor o igual a 36 semanas, que requirieron reanimación avanzada y presentaron, al menos, una de las siguientes condiciones: alteraciones neurológicas tempranas, falla orgánica múltiple o aparición de un evento centinela. Los controles se definieron como neonatos sin diagnóstico de asfixia, nacidos hasta con una semana de diferencia con respecto al caso y de edad de gestación comparable. Se excluyeron los pacientes con malformaciones congénitas mayores y síndromes. Resultados: Se estudiaron 56 casos y 168 controles. El desprendimiento prematuro de la placenta (odds ratio, OR=41,09; IC95% 4,61-366,56), un trabajo de parto con fase expulsiva prolongada (OR=31,76; IC95% 8,33-121,19), no usar oxitocina (OR=2,57; IC95% 1,08-6,13) y ser madre soltera (OR=2,56; IC95% 1,21-5,41) fueron factores de riesgo para el desarrollo de asfixia perinatal en la población bajo estudio. En las madres de los casos se encontraron dificultades sociales en mayor proporción. Conclusiones: Se recomienda un control adecuado y una vigilancia apropiada del trabajo de parto, hacer un estricto partograma, y una búsqueda activa, de manera que cada mujer embarazada tenga un adecuado control prenatal y reciba apoyo social.

¿Es posible disminuir la incidencia de encefalopatía hipóxico isquémica? / Is it possible to reduce the incidence of hypoxic-ischemic encephalopathy?

Objetivo: Determinar si una política local, establecida en la Maternidad del Hospital Padre Hurtado (HPH), para bajar la incidencia de Encefalopatía Hipóxico Isquémica es efectiva, sin incrementar en forma relevante la tasa de cesáreas. Diseño: Estudio de cohorte. Escenario: Unidad de Gestión Clínica de la Mujer y el Recién Nacido del Hospital Padre Hurtado. Población: Neonatos mayores de 33 semanas de edad gestacional, nacidos en el Hospital Padre Hurtado durante los años 1999 y 2015. Método: Se revisaron los resultados de una política de intervención para prevención de asfixia neonatal establecida en la Maternidad del Hospital Padre Hurtado durante un periodo de 14 años. Resultados: Al analizar los datos de un total de 102.612 nacidos vivos, se constató una disminución en la incidencia de EHI en sus 3 grados de una tasa de 4.75/1.000 nacidos vivos previo a la intervención (grupo control) a una tasa de 1.46 por 1.000 nacidos vivos post intervenciones, con alta significancia estadística (p=0,008), llegando en los últimos 6 años a tasa promedio de 0.87/1.000 nacidos vivos. La tasa de EHI moderada y severa bajó de 1.15 por mil nacidos vivos a 0.62, también con alta significancia estadística (p=0.02). La tasa de cesáreas oscilo entre 26-29 % en estos años. Conclusión: La introducción de intervenciones protocolizadas y sistematizadas por medio de la implementación de guías de manejo del trabajo de parto, la capacitación del equipo de profesionales y la auditoría continua de los casos de EHI en el Servicio de Maternidad del Hospital Padre Hurtado se asoció a una disminución significativa de EHI, manteniendo la tasa de cesáreas bajo 30%.

Objectives: Determine whether a local policy to reduce the incidence of neonatal hypoxic-ischemic encephalopathy (HIE), established at the Maternity Unit of Hospital Padre Hurtado (HPH), is effective without significantly increasing the cesarean rate. Design: Cohort study. Setting: Maternity unit of Hospital Padre Hurtado. Population: Newborns older than 33 weeks born at Hospital Padre Hurtado between 1999 and 2015. Methods: The results of a training policy to prevent HIE and perinatal asphyxia established at the Maternity unit of Hospital Padre Hurtado were reviewed during a period of 14 years. Results: From a total of 102.612 newborns analyzed, results showed a decrease in all grades of HIE incidence, from a rate of 4.75 / 1,000 live births prior to intervention (control group) to a rate of 1.46 per 1,000 live births after interventions, with high statistically significance (p=0.008), it reached an average rate of 0.87/1000 for the last 6 years. The moderate and severe HIE rate decreased from 1.15/1000 to 0.62/1000, also with high statistically significance (p=0.02). During the same period of time, the cesarean rate varied between 26-29%. Conclusion: The introduction of protocolized and systematized interventions trough the implantation of Management guides, obstetrics emergency trainings to the professional team and continues audit of the HIE cases at the Maternity unit Hospital Padre Hurtado was associated to a significant decrease of HIE, maintaining the rate of cesareans below 30%.

[Clinical features of strabismus in psychomotor retardation]. / Características clínicas del estrabismo en retraso psicomotor.

BACKGROUND: In psychomotor retardation there is an abnormal development of mental, sensory and motor skills associated with ocular manifestations. There are biological and psychosocial risk factors that predispose an individual to neurological damage. From 50% to 80% of patients with strabismus retardation have special features that differentiate it from the rest of strabismus in healthy patients. OBJECTIVE: To determine the most common type of strabismus in patients with psychomotor retardation and their clinical features. MATERIAL AND METHODS: Patients with psychomotor retardation and strabismus were included. An ophthalmological examination was performed, as well as an evaluation of the characteristics of strabismus, including perinatal and post-natal history. RESULTS: Esotropia was the most frequent squint with 65.3%, followed by exotropia with 32.7%. The variability in the squint magnitude was 60% in both types, and 6 patients had dissociated vertical deviation. Most of the patients started to present strabismus since they were born. The most frequent perinatal risk factors were threatened miscarriage, pre-eclampsia, foetal distress, and hypoxia. CONCLUSIONS: Esotropia is the most common type of strabismus in psychomotor retardation. The variability of squint magnitude is a characteristic in these patients. The moderate variability is the most frequent in both esotropia and exotropia. The most common refractive error is hyperopic astigmatism in esotropia and the myopic kind in exotropia.

Neonatal near miss: a systematic review.

BACKGROUND: The concept of neonatal near miss has been proposed as a tool for assessment of quality of care in neonates who suffered any life-threatening condition. However, there are no internationally agreed concepts or criteria for defining or identifying neonatal near miss. The purpose of this study was to perform a systematic review of studies and markers that are able to identify neonatal near miss cases and predict neonatal mortality. METHODS: Electronic searches were performed in the Medline, Embase and Scielo databases, with no time or language restriction, until December 2014. The term "neonatal near miss" was used alone or in combination with terms related to neonatal morbidity/mortality and neonatal severity scores. Study selection criteria involved three steps: title, abstract and full text of the articles. Two researchers performed study selection and data extraction independently. Heterogeneity of study results did not permit the performance of meta-analysis. RESULTS: Following the inclusion and exclusion criteria adopted, only four articles were selected. Preterm and perinatal asphyxia were used as near miss markers in all studies. Health indicators on neonatal morbidity and mortality were extracted or estimated. The neonatal near miss rate was 2.6 to 8 times higher than the neonatal mortality rate. CONCLUSIONS: Pragmatic and management criteria are used to help develop the neonatal near miss concept. The most severe cases are identified and mortality is predicted with these criteria. Furthermore, the near miss concept can be used as a tool for evaluating neonatal care. It is the first step in building management strategies to reduce mortality and long-term sequelae.

Adverse perinatal outcomes for advanced maternal age: a cross-sectional study of Brazilian births / Resultados perinatais adversos em mulheres com idade materna avançada: estudo transversal com nascimentos brasileiros

ABSTRACT OBJECTIVES: To investigate the risk of adverse perinatal outcomes in women aged ≥41 years relatively to those aged 21-34. METHODS: Approximately 8.5 million records of singleton births in Brazilian hospitals in the period 2004-2009 were investigated. Odds ratios were estimated for preterm and post-term births, for low Apgar scores at 1 min and at 5 min, for asphyxia, for low birth weight, and for macrosomia. RESULTS: For pregnant women ≥41, increased risks were identified for preterm births, for post-term births (except for primiparous women with schooling ≥12 years), and for low birth weight. When comparing older vs. younger women, higher educational levels ensure similar risks of low Apgar score at 1 min (for primiparous mothers and term births), of low Apgar score at 5 min (for term births), of macrosomia (for non-primiparous women), and of asphyxia. CONCLUSION: As a rule, older mothers are at higher risk of adverse perinatal outcomes, which, however, may be mitigated or eliminated, depending on gestational age, parity, and, especially, on the education level of the pregnant woman.

RESUMO OBJETIVOS: Investigar o risco de resultados perinatais adversos em mulheres ≥ 41 anos relativamente àquelas com idade 21-34. MÉTODOS: Cerca de 8,5 milhões de registros de nascimentos únicos em hospitais brasileiros no período 2004-2009 foram investigados. Odds ratios foram estimados para nascimentos prematuros e pós-termo, baixos índices de Apgar no 1° e 5° minutos, asfixia, baixo peso ao nascer e macrossomia. RESULTADOS: Para as mulheres grávidas ≥ 41, aumento de riscos foram identificados para nascimentos prematuros, partos pós-termo (com exceção de primíparas com escolaridade ≥ 12 anos) e baixo peso ao nascer. Relativamente a mulheres mais velhas vs. mais jovens, maiores níveis de escolaridade garantem riscos semelhantes de baixo índice de Apgar no 1° minuto (para primíparas e nascimentos a termo), de baixo índice de Apgar no 5° minuto (para nascimentos a termo), de macrossomia (para não primíparas) e de asfixia. CONCLUSÃO: Em geral, mães mais velhas estão sob maiores riscos de desfechos perinatais adversos, mas esses são minimizados ou eliminados a depender da idade gestacional, da paridade e, em especial, da escolaridade da gestante.

Serial neutrophil values facilitate predicting the absence of neonatal early-onset sepsis.

OBJECTIVE: To validate established neonatal neutrophil reference ranges (RRs) and determine the utility of serial measurements of neutrophil values in the first 24 hours to predict the absence of neonatal early-onset sepsis (EOS). STUDY DESIGN: Retrospective study of 2073 admissions to the neonatal intensive care unit (2009-2011). Neonates were classified as blood culture-positive, proven EOS (n = 9), blood culture-negative but clinically suspect EOS (n = 292), and not infected (n = 1292). Neutrophil values from 745 not-infected neonates without perinatal complications were selected to validate RR distributions. Positive and negative predictive values were calculated; area under receiver operating characteristic curves (AUCs) were constructed to predict the presence or absence of EOS. Neutrophil value scores were established to determine whether serial neutrophil values predict the absence of EOS. RESULTS: Seventy-seven percent of admissions to the neonatal intensive care unit were evaluated for EOS: 9 (0.56%) had proven EOS with positive blood culture ≤ 37 hours; 18% had clinically suspect EOS. Neutropenia occurred in preterm neonates, and nonspecific neutrophilia was common in uninfected neonates. The distribution of neutrophil values differed significantly between study groups. The specificity for absolute total immature neutrophils and immature to total neutrophil proportions was 91% and 94%, respectively, with negative predictive value of 99% for proven and 78% for proven plus suspect EOS. Absolute total immature neutrophils and immature to total neutrophil proportions had the best predictability for EOS >6 hours postnatal with an AUC ∼ 0.8. Neutrophil value scores predicted the absence of EOS with AUC of 0.9 and 0.81 for proven and proven plus suspect EOS, respectively. CONCLUSION: Age-dependent neutrophil RRs remain valid. Serial neutrophil values at 0, 12, and 24 hours plus blood culture and clinical evaluation can be used to discontinue antimicrobial therapy at 36-48 hours.

[Cow's milk protein allergy in disability children]. / Alergia a las proteínas de leche de vaca en niños con discapacidad.

BACKGROUND: Cow's milk protein allergy (CMPA) is the most common food allergy in children. However, the prevalence of CMPA in disability children is unknown. OBJECTIVE: To know the frequency of CMPA in disability children and to assess the clinical improvement after a suppression diet. MATERIAL AND METHODS: We conducted a cohort study at the Children's Rehabilitation Center Telethon of Puebla, in which children aged 6 months to 5 years with clinical symptoms of CMPA were included, between January and September 2012. An exploratory questionnaire about clinical symptoms of CMPA was applied before and after the cow's milk proteins suppression diet. RESULTS: We identified 26 cases among 145 assessed children (18%). The mean age was 2 years and 7 months. All children had a history of multiple clinical symptoms. Respiratory symptoms were the most common, follows for gastrointestinal symptoms, including regurgitation, which suggests the association with gastroesophageal reflux. CONCLUSIONS: CMPA is frequent in disability children. Respiratory and gastrointestinal symptoms were the most common. Cow's milk proteins suppression diet was a useful diagnostic and therapy tool for these children.

ANTECEDENTES: la alergia a las proteínas de la leche de vaca es la alergia alimentaria más frecuente en niños. Sin embargo, se desconoce la prevalencia de ésta en niños con discapacidad. OBJETIVO: conocer la frecuencia de alergia a las proteínas de la leche de vaca en niños con discapacidad y evaluar la mejoría clínica posterior a una dieta de supresión. MATERIAL Y MÉTODO: estudio de cohorte efectuado en pacientes con datos clínicos de alergia a las proteínas de la leche de vaca, de seis meses a cinco años de edad, atendidos en el Centro de Rehabilitación Infantil Teletón de Puebla, de enero a septiembre de 2012. Se aplicó un cuestionario de manifestaciones clínicas de alergia a las proteínas de la leche de vaca antes y después de una dieta de supresión de proteínas de leche de vaca. RESULTADOS: se identificaron 26 casos entre 145 niños evaluados (18%). La media de edad fue de 2 años y 7 meses. Todos los niños tenían antecedentes de múltiples manifestaciones clínicas; las más frecuentes fueron las respiratorias, seguidas por las digestivas, que incluyeron regurgitaciones, lo que sugiere asociación con reflujo gastroesofágico. Todos los pacientes mostraron mejoría clínica después de la dieta de supresión. CONCLUSIONES: la alergia a las proteínas de la leche de vaca es frecuente en niños con discapacidad. Las manifestaciones respiratorias y digestivas fueron las más comunes. La dieta de supresión de proteínas de leche de vaca resultó en un procedimiento diagnóstico y de tratamiento de gran valor en este grupo de niños.

Neonatal near miss approach in the 2005 WHO Global Survey Brazil.

OBJECTIVES: To explore the use of the neonatal near miss concept as a tool to evaluate the quality of neonatal care, as 3 million early neonatal deaths occur every year around the world and the majority of these deaths are avoidable and take place in developing countries. METHODS: This is a secondary analysis of the 2005 WHO Global Survey on Maternal and Perinatal Health, a cross-sectional study, using data from 19 randomly selected Brazilian hospitals. A pragmatic definition of neonatal near miss was developed and tested. Near miss indicators were calculated. RESULTS: Among the 15,169 live born infants included in this analysis, 424 presented at least one of the following conditions: very low birth weight, less than 30 gestational weeks at birth or an Apgar score at the 5th minute of life less than 7. According to the operational definition, these survivors from life-threatening conditions were considered neonatal near miss cases. The early neonatal mortality rate was 8.2/1,000 live births, the neonatal near miss rate was 21.4 neonatal near miss cases/1,000 live births. Substantial variations in the mortality among neonates with life-threatening conditions at birth were observed suggesting intra-hospital quality of care issues. CONCLUSION: The near miss concept and indicators provided information that could be useful to evaluate the quality of care and set priorities for further assessments and health care improvement for newborn infants.

Abordagem do near miss neonatal no 2005 WHO Global Survey Brazil / Neonatal near miss approach in the 2005 WHO Global Survey Brazil

Objetivos: Explorar o uso do conceito de near miss neonatal como uma ferramenta para a avaliação da qualidade do atendimento neonatal, já que 3 milhões de óbitos neonatais precoces ocorrem a cada ano em todo o mundo. A maioria desses óbitos é evitável e ocorre em países em desenvolvimento. Métodos: Esta é uma análise secundária do 2005 WHO Global Survey on Maternal and Perinatal Health, um estudo transversal. Nossa análise incluiu dados de 19 hospitais brasileiros selecionados aleatoriamente. Uma definição pragmática de near miss neonatal foi desenvolvida e testada. Os indicadores de near miss foram calculados. Resultados: Entre os 15.169 nascidos vivos incluídos nesta análise, 424 apresentaram pelo menos uma das seguintes condições: muito baixo peso ao nascer, menos de 30 semanas de gestação ao nascer ou escore de Apgar aos 5 minutos de vida menor que 7. De acordo com a definição operacional, esses sobreviventes de condições com risco de vida foram considerados casos de near miss. A taxa de mortalidade neonatal precoce foi de 8,2/1.000 nascidos vivos, e a taxa de near miss neonatal foi de 21,4 casos/1.000 nascidos vivos. Variações substanciais na mortalidade entre recém-nascidos com condições com risco de vida ao nascer foram observadas, o que sugere a existência de questões relacionadas à qualidade do atendimento intra-hospitalar. Conclusão: O conceito de near miss e os indicadores forneceram informações que poderiam ser úteis para avaliar a qualidade do atendimento e para estabelecer prioridades para outras avaliações e para a melhoria da atenção à saúde dos recém-nascidos.
