RESUMO

Detailed below is a very illustrative case of a rare pathology of recessive congenital methemoglobinemia. The patient, a newborn female, was homozygous for c.535G > A, p.(Ala179Thr) a pathogenic variant in the CYB5R3 gene. The reported population frequency of the allele is 0.853%, demonstrating why it is remarkable to find both parents are heterozygous carriers without consanguinity. A brief review of previously published cases is also presented.

RESUMO

El síndrome de Pallister-Killian (SPK) es una alteración genética rara, no hereditaria y esporádica, que se produce por un mosaicismo para la tetrasomía del brazo corto del cromosoma 12. Se manifiesta con un fenotipo típico, que se caracteriza por un aspecto facial tosco, el labio de Pallister, una nariz corta con narinas antevertidas, un puente nasal plano, hipertelorismo, orejas de implantación baja y malformadas, alopecia en la región bitemporal, anomalías en las extremidades, pigmentación irregular con manchas acrómicas e hipercrómicas y uñas hipoplásicas. Se asocia frecuentemente a hernia diafragmática, alteraciones cardiovasculares y malformaciones anorrectales. Presentamos el primer caso descrito en la literatura de SPK que se manifiesta con un cuadro de obstrucción intestinal (AU)


Pallister-Killian syndrome (PKS) is a rare, non-hereditary, sporadic mosaicism genetic disorder, caused by tetrasomy of the short arm of chromosome 12. It is expressed with a typical phenotype characterized by coarse face with broad, Pallister lip, short nose with anteverted nostrils, flat nasal bridge, hypertelorism, low and malformed ears implantation, bitemporal alopecia, limb abnormalities, irregular pigmentation with achromic and hyperchromic spots and hypoplasic nails. Frequently associated with diaphragmatic hernia, cardiovascular and anorectal malformations. We report the first case in the literature of PKS with associated symptoms of functional intestinal obstruction (AU)

RESUMO

Introducción: La atresia de esófago (AE) comprende un grupo de malformaciones congénitas digestivas por un defecto en la continuidad del esófago. Supone una urgencia quirúrgica neonatal, y requiere un diagnóstico y un tratamiento inmediatos. La incidencia en las distintas series revisadas es de 1:2.500-3.500 recién nacidos. Objetivos: Conocer la epidemiología, la clínica y la evolución de los pacientes con AE tratados en nuestro centro. Pacientes y métodos: Estudio descriptivo y retrospectivo de pacientes ingresados por AE en un hospital terciario en los últimos 6 años. Resultados: Se incluyeron 34 recién nacidos, 15 de los cuales nacieron intramuros (incidencia de 1:1.833); un 61,8% eran varones y un 38,2% mujeres (relación de 1,5:1); la media de la edad gestacional fue de 37,12 ± 2,6 semanas, y la media de peso de 2.516,56 ± 599 g; la edad materna media se situó en 32,76 ± 5,78 años; el 11,8% presentó diabetes gestacional y un 38,2% abortos previos. En las ecografías prenatales, el 47,1% presentó polihidramnios. La distribución por tipo de AE fue la siguiente: I (14,7%), III (82,4%) y IV (2,9%). El síntoma guía principal fue la hipersalivación (38,2%). Un 30% presentó complicaciones postoperatorias; el esofagograma postintervención fue normal en un 80% de los casos. Un 38,2% de los pacientes asoció otras malformaciones; el número medio de días que los pacientes permanecieron sometidos a ventilación asistida fue de 7,66 ± 6,34, y el promedio de días que recibieron nutrición parenteral de 11,27 ± 7. La tasa de fallecimientos fue del 11,8%. Conclusiones: En nuestro medio encontramos una incidencia mayor que la documentada en la bibliografía, aunque una concordancia en la distribución según el tipo de atresia, el sexo y las malformaciones asociadas. También fueron mayores las tasas de diabetes gestacional y abortos previos en nuestra serie. La mortalidad dependió del peso del recién nacido y las malformaciones cardiacas asociadas; en nuestro estudio encontramos uno o ambos factores en los fallecimientos de nuestra serie (AU)


Introduction: Oesophageal atresia (OA) comprises a group of digestive malformations caused by a defect in the continuity of the oesophagus. It entails a neonatal surgical emergency, requiring immediate diagnosis and treatment. The revised incidence in different series is 1:2500-3500 newborns. Objectives: To determine the epidemiology and clinical course of patients with OA treated in our center. Patients and methods: Retrospective and descriptive study of patients admitted for OA in a tertiary hospital in the last 6 years. Results: 34 infants, 15 of whom were born in our hospital (incidence 1:1,833), 61.8% male, 38.2% female (ratio 1.5:1); gestational age 37.12 ± 2.6 weeks; weight at birth 2,516.56 ± 599 g, the average age of their mothers was 32.76 ± 5.78 years; 11.8% had gestational diabetes and 38.2% had previous abortions. In prenatal ultrasound, 47.1% had polyhydramnios. The distribution by type of OA was: I (14.7%), III (82.4%), IV (2.9%). The main guiding symptom was hypersalivation (38.2%). 30% presented postoperative complications; postintervention esophagogram was normal in 80%. 38.2% of patients had other malformations; they pointed an average of assisted ventilation were 7.66 ± 6.34 days and parenteral nutrition 11.27 ± 7 days. Exitus rate: 11.8%. Conclusions: In our area we found a greater incidence than reported in literature with consistency in distribution by type of atresia, sex and associated malfomations. Gestational diabetes and previous abortions rates were higher. Mortality depends on birth weight and associated cardiac malformations, finding one or both criteria in the exitus of our serie (AU)

RESUMO

La displasia broncopulmonar sigue siendo la secuela más frecuente relacionada con los recién nacidos de muy bajo peso al nacer y especialmente con aquellos con pesos extremadamente bajos. Pese a los avances en la prevención y los cuidados de la insuficiencia respiratoria asociada a la prematuridad, no ha ocurrido un descenso en su incidencia en esta población, aunque sí hemos asistido en los últimos años a un cambio en su expresión clínica y en su gravedad. Existen, sin embargo, diferencias aún importantes entre los distintos centros en cuanto a la frecuencia de su presentación, probablemente debido a la aplicación de un diagnóstico clínico no homogéneo. En este artículo, la Comisión de Estándares de la Sociedad Española de Neonatología quiere revisar los criterios diagnósticos de la displasia broncopulmonar para reducir, en la medida de lo posible, la variabilidad intercentro de la misma (AU)


Bronchopulmonary dysplasia is the most common sequelae related to very low birth weight infants, mostly with those of extremely low birth weight. Even with advances in prevention and treatment of respiratory distress syndrome associated with prematurity, there is still no decrease in the incidence in this population, although a change in its clinical expression and severity has been observed. There are, however, differences in its frequency between health centres, probably due to a non-homogeneously used clinical definition. In this article, the Committee of Standards of the Spanish Society of Neonatology wishes to review the current diagnosis criteria of bronchopulmonary dysplasia to reduce, as much as possible, these intercentre differences (AU)

RESUMO

Las gestaciones que conllevan algún riesgo materno y/o fetal no siempre son diagnosticadas en un centro especializado en la atención neonatal, por lo que el transporte posnatal es una parte esencial dentro de la estructura de los servicios sanitarios perinatales. El objetivo del transporte neonatal es trasladar al recién nacido a un centro especializado que disponga de la infraestructura y la experiencia necesarias para su asesoramiento y tratamiento. El transporte ideal del recién nacido es el que se realiza in utero. Desafortunadamente, no todos los problemas pueden detectarse a tiempo para el traslado materno y hasta un 30-50% de ellos pueden presentarse durante el parto o en el periodo neonatal inmediato. Por ello es necesario disponer de conocimientos y medios para la reanimación y la estabilización del recién nacido en el momento del parto y de un sistema de transporte neonatal especializado que permita trasladar a los pacientes con el mismo nivel de cuidados que recibiría en el hospital receptor sin que suponga en ningún caso un deterioro de su salud o un riesgo elevado para ella. La Sociedad Española de Neonatología, a través de su Comisión de Estándares, ha querido revisar y actualizar en este documento las recomendaciones para el transporte intraútero, las indicaciones para el traslado neonatal, la organización y la logística necesarias para realizarlo (personal, comunicación, documentación, medio de transporte y equipamiento), la estabilización previa al mismo, el manejo durante el traslado y el ingreso en el hospital receptor (AU)


During pregnancy, it is not always possible to identify maternal or foetal risk factors. Infants requiring specialised medical care are not always born in centres providing intensive care and will need to be transferred to a referral centre where intensive care can be provided. Therefore Neonatal Transport needs to be considered as part of the organisation of perinatal health care. The aim of Neonatal Transport is to transfer a newborn infant requiring intensive care to a centre where specialised resources and experience can be provided for the appropriate assessment and continuing treatment of a sick newborn infant. Intrauterine transfer is the ideal mode of transport when the birth of an infant with risk factors is diagnosed. Unfortunately, not all problems can be detected in advance with enough time to safely transfer a pregnant woman. Around 30- 50% of risk factors will be diagnosed during labour or soon after birth. Therefore, it is important to have the knowledge and resources to resuscitate and stabilise a newborn infant, as well as a specialised neonatal transport system. With this specialised transport it is possible to transfer newly born infants with the same level of care that they would receive if they had been born in a referral hospital, without increasing their risks or affecting the wellbeing of the newborn. The Standards Committee of the Spanish Society of Neonatology reviewed and updated recommendations for intrauterine transport and indications for neonatal transfer. They also reviewed organisational and logistic factors involved with performing neonatal transport. The Committee review included the type of personnel who should be involved; communication between referral and receiving hospitals; documentation; mode of transport; equipment to stabilise newly born infants; management during transfer, and admission at the referral hospital (AU)

RESUMO

En el año 2004 fue elaborado por el Comité de Estándares y la Junta Directiva de la Sociedad Española de Neonatología (SEN) un primer documento sobre niveles asistenciales y recomendaciones de mínimos para la atención neonatal, a partir del cual se pudo definir el nivel asistencial de cada centro en nuestro país, así como los requerimientos técnico-sanitarios según niveles. La presente revisión pretende tener en cuenta los cambios experimentados en la asistencia neonatal en los últimos años y optimizar la localización de recursos. Las unidades que proporcionan asistencia a los recién nacidos deben estar organizadas dentro de un sistema de regionalización de los cuidados perinatales. Las características funcionales de cada nivel asistencial deben ser definidas de forma uniforme y clara, y esto incluye requerimientos de equipamiento, instalaciones, personal, servicios de apoyo, formación y organización de servicios (incluyendo el transporte) necesarios para cubrir las prestaciones de cada nivel de cuidados (AU)


A policy statement on the levels of care and minimum recommendations for neonatal healthcare was first proposed by the Standards Committee and the Board of the Spanish Society of Neonatology in 2004. This allowed us to define the level of care of each center in our country, as well as the health and technical requirements by levels of care to be defined. This review takes into account changes in neonatal care in the last few years and to optimize the location of resources. Facilities that provide care for newborn infants should be organized within a regionalized system of perinatal care. The functional capabilities of each level of care should be defined clearly and uniformly, including requirements for equipment, facilities, personnel, ancillary services, training, and the organization of services (including transport) needed to cover each level of care (AU)

RESUMO

Introducción. Las agenesias del cuerpo calloso (ACC) constituyen una malformación cerebral frecuente caracterizada por una gran heterogeneidad clínica y etiológica. Las formas aisladas suelen ser esporádicas mientras que las asociadas con otras malformaciones se integran con frecuencia dentro de cuadros sindrómicos o forman parte de ciertas anomalías metabólicas, lo que constituye un factor pronóstico negativo. Objetivos. Estudiar las características de las ACC en nuestro medio, la incidencia de secuelas en los pacientes con ACC y una serie de factores de riesgo relacionados con su aparición. Pacientes y métodos. Estudio retrospectivo descriptivo y comparativo de los pacientes con ACC ingresados en las últimas dos décadas en la Unidad Neonatal. Resultados. N=16. EG. 37,9 ± 3,6 semanas. Varones 6, mujeres 10, parto vaginal 62,5%, cesárea 37,5%, peso: 2.919,4 ± 654,3 g. Dos pacientes con antecedentes de hermanos con ACC y otros dos de epilepsia. Diagnóstico prenatal ecográfico en 11 (68,6%). ACC completa en 13 y en 3 ACC parcial. Motivo ingreso: 12 diagnóstico prenatal , 3 hipotonía y fenotipo peculiar, 1 prematuridad. 43,8% presentaban malformaciones sistémicas asociadas. Un 43,75% de pacientes presentaba ACC aislada y otro 56,25% no aislada, y dentro de este grupo, en 44,4% estaba asociada a malformaciones del sistema nervioso central (SNC), otro 44,4% presentaban tanto malformaciones neurológicas como asociación con síndromes genéticos y un 11,2% asociada a síndromes genéticos. Globalmente un 56,3% presentaron secuelas graves, 37,5% potenciales auditivos tronculares alterados y 3 fueron exitus (18,8%). Encontramos relación significativa entre malformaciones del SNC y formas sindrómicas con déficit motor (p: 0,030), cognitivo (p: 0,04) y plurideficiencias (p: 0,04). Conclusiones: Nuestros resultados confirman que el pronóstico neurológico de las ACC depende fundamentalmente de la presencia de anomalías asociadas (síndromes o malformaciones del SNC), teniendo la neuroimagen papel importante en el consejo prenatal (AU)


Introduction. Agenesis of the corpus callosun (ACC) is a brain malformation characterized by a great clinical and etiological heterogeneity. The isoalted forms are usually sporadic while those associate with other malformations are frequently integrated into syndromes or part of certain metabolic abnormalities, which is a negative prognostic factor. Objectives. To study the cahracteristics of the ACC in our country, the incidence of sequelae in patients with ACC and a number of risk factors related to its appearance. Patients and methods. Retrospective descriptive and comparative study of patients with ACC admitted in the last tow decades in the Neonatal Unit. Results. N=16. EG: 37.9 ± 3.6 weeks. 6 men, 10 women, 62,5% vaginal delivery, caesarean section 37.5%, weight: 2,919.4 ± 657.3 g. Two patients with a history of siblings with ACC and other two epilepsy. Prenatal sonographic diagnosis in 11 (68.8%). Complete in 13 ACC and 3 partial ACC. Reason for admission: 12 prenatal diagnosis, 3 hypotonia and distinctive phenotype, 1 prematurity. 43,8% had associated systemic malformations. A 43.75% of patients had isolated ACC 56.25% other non-isolated, and within this group, 44,4% was associated with malformations of the central nervous system (CNS), another 44,4% had both malformations neurological and genetic syndromes and association with a 11,2% associated with genetic syndromes. Overall 56,3% had a severe sequelae, 37,5% truncal altered auditory potentials and 3 were death (18.8%). We found a significant relationship between CNS malformations and syndromic forms with motor deficit (p = 0.030), cognitive (p= 0.04) and multiple disabilities (p = 0.04). Conclusions. Our results confirm that the neurological outcome of the ACC depends mainly on the presence of associated anomalies (syndromes or malformations of the CNS) having neuroimaging important role in prenatal counseling (AU)

RESUMO

Introducción: Existe una evidencia creciente de que los recién nacidos prematuros son particularmente vulnerables a los efectos adversos de la corioamnionitis. La respuesta inflamatoria fetal a la infección se ha asociado a una mayor incidencia de daño cerebral en esta población. Objetivo: Analizar si la corioamnionitis clínica se asocia a un incremento del riesgo de desarrollar hemorragia intraventricular (HIV) grave (grados III-IV) en los recién nacidos pretérmino más inmaduros en las primeras 72 horas de vida. Pacientes y métodos: Se ha revisado de forma retrospectiva a todos los niños pretérmino nacidos con menos o igual a 28 semanas de gestación tras el inicio espontaneo del trabajo de parto o la rotura prematura de membranas durante el periodo comprendido entre julio de 2006 y febrero de 2009 (se incluyeron 117 recién nacidos prematuros). Los datos prenatales, perinatales y de evolución clínica fueron comparados entre el grupo con HIV grave diagnosticada en las primeras 72 horas de vida y el grupo sin esta complicación. El método estadístico incluyo las pruebas de la t de Student y la U de Mann-Whitney para las variables cuantitativas, y la prueba de la x cuadrado y el cálculo de la odds ratio(OR) para las variables cualitativas. Finalmente, se efectuó un análisis de regresión logística para valorar la relación independiente entre las variables significativas en el análisis univariante. Resultados: El grupo con HIV grave presento una edad gestacional significativamente menor. Los grupos con HIV grave y sin HIV grave no presentaron diferencias significativas en el peso al nacimiento, la puntuación de Apgar al minuto y los 5 minutos, y el parto mediante cesárea. Los recién nacidos con HIV grave precisaron en las primeras 12 horas de vida intubación y requerimientos de oxigeno significativamente mayores, así como un mayor uso de fármacos inotrópicos (p <0,05). A menor exceso de bases en las primeras 12 horas, existía un mayor riesgo de HIV grave en esta población (p= 0,001). En las variables prenatales se encontró una asociación independiente entre la presencia de corioamnionitis clínica y HIV grave (OR=2,66; intervalo de confianza del 95%: 1,14-6,21). Conclusión: La corioamnionitis materna incrementa el riesgo de desarrollar HIV grave en los recién nacidos prematuros con una edad gestacional menor o igual a 28 semanas (AU)


Introduction: There is increasing evidence that the premature newborns are particularly vulnerable to adverse effects of chorioamnionitis. The fetal inflammatory response to the infection is associated with an increased incidence of brain injury in this population. Objective: To analyze if the clinical chorioamnionitis is associated with an increased risk of developing severe intraventricular hemorrhage (IVH) (grade III-IV) in the most immature preterm newborns in the first 72 hours of life. Patients and methods: We retrospectively reviewed all preterm newborns delivered at minor/=28 weeks of gestation after spontaneous onset of preterm labor or preterm membrane rupture during the period July 2006-February 2009 (117 preterm newborns were included). Prenatal, perinatal and clinical evolution data were compared between the group with severe IVH diagnosed in the first 72 hours of life and the group without this complication. Statistical methods included t student test and UMann-Whitney test for quantitative variables and x cuadrado test and odds ratio (OR) estimation for qualitative variables. Finally, a logistic regression analysis was performed to evaluate the independent relationship among significant variables at univariate analysis. Results: Severe IVH group had a significant lower gestational age. The group with severe IVH and that without severe IVH was not significantly different in birth weight, 1 and 5 minute apgar scores and caesarean delivery. Newborns with severe IVH require in the first 12 hours of life intubation and significant higher oxygen and inotropic drugs requirements (p <0.05). A lower base excess in the first 12 hours was associated with an increased risk of severe IVH in this population(p= 0.001). Among the prenatal variables an independent association between clinical chorioamnionitis and severe IVH was found (OR: 2.66; CI 95%: 1.14-6.21). Conclusion: Maternal chorioamnionitis increases the risk of developing severe IVH among preterm newborns delivered at minor/ = 28 weeks of gestation (AU)

RESUMO

Introducción. La incidencia del ductus arteiroso persistente (DAP) es considerable en el recién nacido prematuro. La indometacina se ha demostrado como terapia efectiva del DAP y el porcentaje de cierre está condicionado por múltiples variables. El objetivo del estudio fue determinar factores predictivos del éxito del tratamiento con indometacina en recién nacidos prematuros. Métodos. Se analizó de forma retrospectiva una cohorte de 56 recién nacidos menores o iguales de 30 semanas de edad gestacional y/o 1.500 gramos que recibieron tratamiento con indometacina en el periodo comprendido entre octubre de 2006 y julio de 2009. Resultados. La indometacina fue efectiva en 38 recién nacidos (70,4%) , requiriendo cirugía solo en 14 casos (25,9%). El análisis estadístico mostró que solo fueron factores predictivos de cierre ductal y que, por tanto, condicionaron el resultado el tratamietno con indometacina, la edad gestional, el peso, el tamaño del DAP, el Apgar al minuto, el grado de asistencia ventilatoria, las dosis de surfactante recibidas y la cantidad de líquidos administrados al nacimiento. Conclusiones. La indometacina es efectiva para el tratamiento del ductus hemodinámicamente significativo en recién nacidos prematuros. Mayor peso, edad gestacional, menor tamaño del ductus, mayor Apgar al minuto, menor requerimiento de surfactante y menor soporte respiratorio fueron factores predictivos de una mayor tasa de cierre (AU)


Introduction. The incidence of persistent ductus arteriosus (PDA) is considerable in the premature newborn. Indomethacin has been demonstrated to be an effective therapy of PDA and the percentage of closure is conditioned by multiple variables. This study has aimed to determine predictive factors of treatment success with indomethacin in premature newborns. Methods. A cohort of 56 newborns under the age or (70,4%), surgery being required in only 14 cases (25.9%). The statistical analyses showed that only the following were predictive factors of ductal closure and therefore that these were the only ones to condition the result of treatment with indomethacin: gestational age, weight, PDA size, one-minute Apgar, grade of assisted ventilation, surfactant dose received and the amount of fluids administered on birth. Conclusions. Indomethacin is effective for the treatment of hemodynamically significant ductus in premature newborns. Greater weight, gestational age, smaller size of the ductus, higher one-minute Apgar score, lower requirement of surfactant and lower respiratory support were predictive factors of a greater closure rate (AU)

RESUMO

Introducción: Evaluar si la presencia de persistencia de ductus arterioso (PDA) aumenta la proporción de retinopathy of prematurity (ROP, «retinopatía del prematuro») o su gravedad. Pacientes y método: Se incluyó en el estudio una cohorte consecutiva de prematuros diagnosticados de PDA por ecocardiograma nacidos en el Hospital Universitario Miguel Servet desde enero de 2006 hasta mayo de 2009. Comparamos la proporción y gravedad de ROP en este grupo en comparación con un grupo control sin PDA aleatoriamente elegido. Resultados: Estudiamos un total de 131 prematuros: 79 con PDA y 52 sin PDA. Encontramos relación estadísticamente significativa entre la presencia de PDA y la proporción de ROP (p=0,03) (OR=2,41; 95% CI 1,08–5,38), sin que existieran diferencias significativas en la edad gestacional (EG) entre los grupos. Sin embargo, al usar un modelo de regresión múltiple ajustado a la EG, hay una relación significativa entre ROP y EG (β=−0,322; p=0,003), pero no existe relación estadísticamente significativa entre ROP y PDA (p=0,073 para proporción de ROP y p=0,20 para estadio de ROP). Conclusiones: La presencia de PDA no aumenta el riesgo de desarrollar ROP ni su gravedad, una vez que se considera el efecto de la EG en la presencia de PDA (AU)


Objective: To evaluate whether the presence of patent ductus arteriosus (PDA) increases the rate of retinopathy of prematurity (ROP) or its severity. Patients and method: A consecutive cohort of premature infants diagnosed with PDA by echocardiography born in the Miguel Servet University Hospital from January 2006 to May 2009 was included in the study. We compared the rate and severity of ROP in this group of patients with a control group of randomly-chosen premature infants with a normal echocardiography. Results: We evaluate a total of 131 premature infants (79 with PDA and 52 without PDA). We found a statistically significant association between the presence of PDA and the rate of ROP (p=0.03) (OR=2.41; 95% CI 1.08–5.38). However, using a multiple regression model adjusted for the gestational age (GA), a significant reverse association was found between ROP and GA (β=−0.322; p=0.003), but there was no statistically significant correlation between ROP and PDA (p=0.073 for rate of ROP and a p=0.20 for stage of ROP). Conclusions: The presence of PDA does not increase the risk of developing ROP or its severity, once considered the effect of gestational age in PDA (AU)

However, using a multiple regression model adjusted for the gestational age (GA), a significant reverse association was found between ROP and GA (ß= -0.322; p=0.003), but there was no statistically significant correlation between ROP and PDA (p=0.073 for rate of ROP and a p=0.20 for stage of ROP). CONCLUSIONS: The presence of PDA does not increase the risk of developing ROP or its severity, once considered the effect of gestational age in PDA.
