La habilidad lingüística en el primer ciclo de Educación Primaria en alumnado nacido prematuro extremo / Linguistic ability in the first cycle of Education Primary of students born prematurely extreme

La prematuridad tiene una alta tasa de incidencia en los países desarrollados, representando el 75% de la mortalidad perinatal. Aunque los avances prenatales y perinatales de las últimas décadas han permitido reducir su prevalencia, en consecuencia, se ha hecho evidente la presencia de morbilidades y comorbilidades en el desarrollo de estos infantes.El propósito de esta investigación, de carácter prospectivo y longitudinal, es analizar los componentes del lenguaje (morfología, sintaxis, semántica y pragmática) de 29 menores, nacidos prematuros extremos, en el Hospital Universitario La Paz de Madrid y que actualmente están en edad escolar obligatoria, para identificar la presencia de posibles dificultades en el lenguaje. Todos los participantes estaban matriculados en Educación Primaria y los componentes del lenguaje se evaluaron a través de la batería BLOC-Screening.Los resultados evidencian que existen comorbilidades en el componente morfológico en los siguientes elementos: formas irregulares de pasado, formas irregulares de futuro, reflexivos…; en el componente semántico (locativos, cuantificadores, modificadores de tiempo y sucesión…) y en sintaxis (voz pasiva, oraciones comparativas, oraciones subordinadas de causa y condición, y en las temporales [después/antes]…), obteniéndose mejores resultados en el componente pragmático, excepto en aquellas acciones que requieren expresar demandas y solicitar información específica.Por tanto, el perfil obtenido en lenguaje de los prematuros extremos sugiere la necesidad de intervención logopédica y conlleva la necesidad de hacer propuestas de intervención didáctica en la escuela que mejoren sus habilidades lingüísticas desde un enfoque comunicativo.(AU)

Prematurity has a high incidence rate in developed countries, accounting for 75% of perinatal mortality. Although pre- and perinatal advances in recent decades have reduced its prevalence, consequently, the presence of morbidities and comorbidities in the development of these infants has become evident.The purpose of this prospective and longitudinal research is to analyze the language components (morphology, syntax, semantics and pragmatics) of 29 minors, born extremely premature, at the Hospital Universitario La Paz in Madrid and who are currently of compulsory school age, in order to identify the presence of possible language difficulties. All the participants were enrolled in Primary Education and the language components were assessed using the BLOC-Screening battery.The results show that there are comorbidities in the morphological component in the following elements: irregular forms of the past, irregular forms of the future, reflexive…; in the semantic component (locatives, quantifiers, modifiers of time and succession…) and in syntax (passive voice, comparative clauses, subordinate clauses of cause and condition, and in the temporal ones [after/before]…), obtaining better results in the pragmatic component, except in those actions that require expressing demands and requesting specific information.Therefore, the profile obtained in the language of extremely premature infants suggests the need for speech therapy intervention and entails the need to make proposals for educational intervention at school that improve their language skills from a communicative approach.(AU)

Evaluación de la función tiroidea en el recién nacido pretérmino o de muy bajo peso / Assessment of thyroid function in the preterm and/or very low birth weight newborn

El Programa de cribado o detección precoz del hipotiroidismo congénito es uno de los mayores avances logrados en Pediatría. Las hormonas tiroideas son imprescindibles para el desarrollo y la maduración cerebral, que continúan en la etapa neonatal. Las alteraciones de la función tiroidea en niños prematuros y con bajo peso en los primeros meses de vida origina lesiones irreversibles en el sistema nervioso central y es una de las causas más frecuentes y evitables de retraso mental. El diagnóstico en el periodo neonatal es difícil, por lo que requiere estudio analítico para poder efectuar el tratamiento adecuado.La relevancia de este problema justifica su difusión a todas las áreas de Pediatría. El objetivo principal, evitar el daño cerebral en estos pacientes. Otros aspectos para optimizar el desarrollo adecuado de estos niños con todos los controles periódicos necesarios y lograr la inclusión del diagnóstico de las alteraciones tiroideas durante la estancia en unidades neonatales y en los primeros meses de vida precisan implementar los recursos de los centros sanitarios y continuar avanzando según los conocimientos actuales.En el presente documento nos centraremos en el cribado de los recién nacidos pretérmino (< 32 semanas de gestación) o con muy bajo peso para la edad gestacional (1.500-1.000 g muy bajo peso al nacer, o<1.000 g peso extremadamente bajo al nacer) y la protocolización de evaluación de función tiroidea en prematuros.Actualizamos los procedimientos diagnósticos, las pruebas imprescindibles y complementarias requeridas, la etiología y los diagnósticos diferenciales en esta patología.

The screening program or early detection of congenital hypothyroidism is one of the greatest advances achieved in Pediatrics. Thyroid hormones are essential for brain development and maturation, which continue into the neonatal stage. Alterations in thyroid function in premature and underweight children in the first months of life causes irreversible damage to the central nervous system and is one of the most frequent and avoidable causes of mental retardation. Diagnosis in the neonatal period is difficult, so it requires an analytical study to be able to carry out the appropriate treatment.The relevance of this problem justifies its communication to all areas of pediatrics. The main objective is to avoid brain damage in these patients. Other aspects to optimize the adequate development of these children with all the necessary periodic controls and to achieve the inclusion of the diagnosis of thyroid alterations during the stay in neonatal units and in the first months of life, need to implement the resources of the health centers and continue advancing according to current knowledge.In this document, we will focus on the screening of preterm newborns VLBW (<32 weeks of gestation) and/or very low weight for gestational age (1500-1000g VLBW or <1000g) and the function evaluation protocol thyroid in premature babies.We update the diagnostic procedures, the essential and complementary tests required, the etiology and the differential diagnoses in this pathology.

[Occupational exposures, diet and storing: Recommendations to reduce environmental pollutants in breastfeeding]. / Exposiciones laborales, dieta y envasado: recomendaciones para reducir los contaminantes medioambientales en la lactancia materna.

The pollution of the planet also reaches the breastfeeding ecosystem, one of the most intimate and inviolable that links us as an animal species to the rest of mammals. Nursing mothers may be concerned about whether the quality of their milk will be adequate for their baby and whether environmental pollutants through work, diet, and storing may adversely affect their child. Breast milk is a source of exposure to environmental pollutants, and at the same time it counteracts much of the effects of these exposures. An approach based on the principles of reality and precaution of environmental health to avoid, reduce or eliminate the production and use of harmful chemicals during pregnancy and lactation would improve the human and planetary health for the offspring.

Thyroid Volume Assessment in 3-14 Year-Old Spanish Children from an Iodine-Replete Area.

BACKGROUND/AIMS: Few data exist on reference thyroid volumes (Tvols) for Spanish children. The standard tables of the World Health Organization (WHO) are only for children older than 6 years. The present cross-sectional study reports the normal Tvols of 3-14 year-old girls and boys living in Madrid (Spain). METHODS: The study subjects were 217 children aged 3-14 years. Urinary iodine was determined, and, on the same day, cervical ultrasound examinations were performed by a single, experienced paediatric radiologist. The sex-specific, upper normal limits for Tvol were then determined, based on age and body surface area (BSA). RESULTS: The median urinary iodine concentration was 120 µg/L (interquartile range 80-184); the population was therefore deemed to fall within the optimum range for iodine nutritional status. Eight children with heterogeneous glandular parenchyma were detected, as were 6 with increased vascularity, and 22 with intrathyroid cysts. Tvol increased with age and BSA in both sexes from the age of 3 years. In girls aged 11-12 years, Tvol was significantly larger than that in boys of the same age. When comparing children 6 years old and above, the 97th percentile Tvols with respect to gender/BSA were similar to WHO reference values, but by gender/age they were 30% larger. CONCLUSIONS: This work proposes reference ultrasound-determined Tvols for 3-14-year-old children living in Madrid.

Recomendaciones para la vacunación frente al ROTAvirus de los recién nacidos PREMaturos (ROTAPREM) / Recommendations for vaccination against ROTAvirus in PREMature newborns (ROTAPREM)

El rotavirus (RV) es la causa principal de diarrea infantil grave en todo el mundo e infecta prácticamente a todos los niños en los primeros 5 años de vida, sobre todo en los primeros 2años. Existen dos vacunas atenuadas de administración oral frente al RV disponibles en nuestro medio que han demostrado ser seguras y eficaces frente a la enfermedad. El objetivo principal de estas vacunas ha sido reproducir la historia natural de la infección y proteger frente a la enfermedad grave en los primeros meses de vida. Los recién nacidos prematuros son especialmente vulnerables a la enfermedad por RV, no solo por tener más riesgo de adquirir la infección, sino también por sus complicaciones. La vacunación frente al RV en niños prematuros ha mostrado resultados de eficacia y seguridad similares a los comunicados en niños a término, y los datos existentes sugieren un riesgo bajo de diseminación e infección nosocomial cuando la vacunación se realiza durante la hospitalización. Dado que un porcentaje estimable de recién nacidos prematuros permanecen ingresados en las unidades neonatales más allá de las 12semanas de vida, se considera que estos, siempre que su condición clínica lo permita, deben recibir la vacunación frente al RV sin retrasos, incluso durante la hospitalización si así fuese necesario

Rotavirus (RV) is the leading cause of severe acute gastroenteritis in infants worldwide. Most children are infected by RV by the age of 5 years, and especially in the first 2 years. Two oral attenuated vaccines against RV are licensed in industrialised countries, which have proven to be safe and effective against the disease. The main objective of these vaccines has been to reproduce the natural history of infection and protect against severe disease in the first months of life. Preterm infants are at higher risk of severe RV infection compared to full-term infants and infants with normal birth weight. Data collected on RV vaccination in preterm infants demonstrated that RV vaccines are effective and safe, compared with full-term infants, with a marginal risk of horizontal viral transmission and dissemination when vaccination is performed during hospitalisation. Preterm infants frequently require admission to hospital after the beginning of the 12 th week of life, which suggests that they should receive RV vaccines during admission according to the official immunisation schedule

Diagnóstico y seguimiento de los pacientes con hipotiroidismo congénito diagnosticados por cribado neonatal / Diagnosis of OHVIRA syndrome in prepuberty: Is it possible?

El Programa de cribado o detección precoz del hipotiroidismo congénito (HC) es uno de los mayores avances logrados en Pediatría. Las hormonas tiroideas son imprescindibles para el desarrollo y la maduración cerebral, que continúan en la etapa neonatal. El hipotiroidismo de comienzo en los primeros meses de vida origina lesiones irreversibles en el sistema nervioso central y es una de las causas más frecuentes y evitables de retraso mental. El diagnóstico clínico es tardío, por lo que requiere estudio analítico para poder efectuar el tratamiento adecuado. Este artículo actualiza los objetivos, los procedimientos diagnósticos, las pruebas imprescindibles y complementarias requeridas, la etiología y los diagnósticos diferenciales en esta patología. Con especial énfasis en los requerimientos de los centros de seguimiento para protocolizar los resultados del tratamiento con L-tiroxina administrada de forma inmediata al diagnóstico y a las dosis que eviten fases de infra o supradosificación que pueden alterar diversos aspectos del desarrollo cognitivo. La revaluación de etiología permanente vs. transitoria se recomienda siempre después de los 3 años de edad. La relevancia de este programa precisa su difusión a todas las áreas de pediatría. El objetivo principal, evitar el daño cerebral en estos pacientes, se ha logrado y es además altamente beneficioso desde el punto de vista económico. Otros aspectos para optimizar los resultados cognitivos con todos los controles periódicos necesarios y lograr la inclusión del diagnóstico del HC central, precisan implementar los recursos de los centros de seguimiento y continuar avanzando según los conocimientos actuales

The screening program of congenital hypothyroidism (CH) is probably one of the best achievements in paediatrics. Thyroid hormones are essential for brain development and brain maturation that continue through the neonatal period. Hypothyroidism that begins in the first months of life causes irreversible damage to the central nervous system, and is one of the most frequent and preventable causes of mental retardation. As children with congenital hypothyroidism are born with a normal appearance, analytical studies are required to immediately start the appropriate therapy. This article analyses the aims, diagnostic procedures, tests required, aetiology, and differential diagnosis in this disorder. Especially relevant is to perform frequent monitoring to ensure dose adjustments of L-Thyroxine therapy, avoiding infra- or supra-dosing that negatively affects neurosensory functions. Re-evaluation of the aetiology permanent vs transient hypothyroidism is always recommended after 3 years of chronological age. The relevance of this screening program should be widely discussed in paediatrics. The main objective is to avoid cerebral damage in these patients and has been highly successful and economically beneficial. Other aspects are required to optimise patient outcomes, to perform all the controls according to the recommendations and to include, in the near future, the diagnosis of central hypothyroidism. Implementation of this program is necessary to progress in accordance with current scientific knowledge

Recomendaciones para el diagnóstico y seguimiento del feto y del recién nacido hijo de madre con patología tiroidea autoinmune / Recommendations for the diagnosis and follow up of the foetus and newborn child born to mothers with autoimmune thyroid disease

El objetivo de este documento es revisar las recomendaciones actuales en el manejo del hijo de madre con patología autoinmune tiroidea. En este 2017 se ha publicado la guía de la Asociación Americana de Tiroides para el diagnóstico y manejo de la enfermedad tiroidea durante el embarazo y el posparto. En dicha guía se establecen 97 recomendaciones y se propone un algoritmo de diagnóstico y tratamiento del hipotiroidismo gestacional. También en este último año se ha publicado una amplia revisión sobre el abordaje fetal y neonatal del hijo de madre con enfermedad de Graves. Se insiste en la trascendencia de la determinación de anticuerpos maternos frente al receptor de TSH en la segunda mitad del embarazo para estratificar adecuadamente el riesgo en el neonato

Also, in this last year, a wide review was been published on the foetal and neonatal approach of the child of a mother with Graves’ disease. The importance of the determination of maternal antibodies against thyrotropin receptor in the second half of pregnancy is stressed, in order to adequately stratify the risk in the neonate

¿Es suficiente la nutrición de yodo en la población infantil española? Revisión histórica y situación actual / Is iodine nutrition in the Spanish pediatric population adequate? Historical review and current situation

El yodo es un componente esencial de las hormonas tiroideas y su déficit es la causa principal de retraso mental prevenible en el mundo. España ha sido considera yododeficiente hasta 2003. A pesar de que desde 2004, la yoduria está en rango óptimo, la OMS reconoce que no se cumplen los requisitos necesarios para garantizar que la población no pueda sufrir un trastorno por déficit de yodo. El objetivo de este artículo es realizar una revisión de la situación nacional de este micronutriente. Los datos obtenidos en diversos estudios destacan el bajo consumo domiciliario de sal yodada. A pesar de los avances conseguidos en las últimas décadas, los niños españoles no están exentos de sufrir un trastorno por déficit de yodo. Es necesario, por tanto, implementar políticas que permitan controlar la nutrición yódica así como impulsar el consumo de sal yodada de manera universal

Iodine is an essential component of thyroid hormones, and iodine deficit is the leading cause of preventable mental retardation worldwide. Spain was considered iodine-deficient until 2003. Although iodine urinary levels have been in the optimal range in Spain since 2004, the WHO recognizes that our country does not meet the necessary requirements to ensure that the whole population is not at risk of an iodine deficiency disorder. The aim of this article is to review the current iodine status in Spain. Data from several studies emphasize the low consumption of iodized salt at home. Despite the progress made in recent decades, Spanish children are not exempt from suffering an iodine deficiency disorder. Policies that allow for controlling iodine nutrition and promote universal consumption of iodized salt should therefore be implemented

Developmental Outcomes, Attachment and Parenting: Study of a Sample of Spanish Premature Children.

The aim of this study is to provide an overview of the development of premature children, including attachment, child psychological adjustment and parental variables. 130 children < 1,500 g or < 32 weeks at birth from two public hospitals, assessed at two years corrected age, together with their parents. Parental socio-demographic data was collected. Infant development, attachment and child psychological adjustment were evaluated, as was parental stress. The percentage of preterm children with developmental delays ranged from 5% to 21%. Girls tend to show higher levels of development than boys with effect sizes ranging from small, η2p = .02, to medium, η2p = .07. Secure attachment was the most frequent pattern in the sample. No significant differences, p < .05, between preterm children and the normative population were found on children´s behavioral problems and maternal stress levels. Despite the fact prematurity is considered to be a risk factor for a child´s development, a significant proportion of these children do not show problems in terms of developmental levels, attachment pattern and maternal stress. However, socio-emotional and affective domains, as well as psychological support programs for parenthood, should be followed up from a multidisciplinary perspective.

Quality of attachment in infants less than 1500g or less than 32weeks. Related factors.

BACKGROUND: Prematurity carries a high risk of mortality and sequelae, altering the bonding process and leading to repercussions in terms of attachment. OBJECTIVE: To assess the type of attachment in children under 32weeks' gestational age (GA) or below 1500g, in hospitals where development-centred care has been implemented and to study the association between various types of attachment and certain neonatal and family characteristics. METHOD: Children <1500g or <32weeks GA who were born or admitted before 48h of life to one of two hospitals in Madrid between January and December 2012 were candidates for the study. The type of attachment was assessed through the strange situation procedure (SSP). Attachment was classified according to three types: secure (B), avoidant (A), or resistant/ambivalent (C). Insecure attachment was considered to be A+C. Children were assessed at a corrected age of 2years using the Bayley III Scales and SSP. Data on the characteristics of the parents and children were collected. RESULTS: A total of 59% (117/199) of the children <1500g or <32weeks GA born in 2012 in the two study hospitals were able to be evaluated. Secure attachment was found in 64% (75/117), avoidant attachment in 12.8% (15/117), and resistant/ambivalent in 23.1% (27/117). The children with secure attachment had a score of 107.6±16 in the cognitive area of the Bayley's Scale versus 98.8±18.8 in those with insecure attachment (p 0.007). Frequency of secure attachment at ≤26weeks GA was 23% (3/13) versus 69% (72/104) in children >26weeks GA (p 0.003). CONCLUSIONS: Nearly two-thirds of the children studied presented secure attachment, which was associated with better cognitive development. The frequency of secure attachment is lower in the children born more preterm.

La importancia de la nutrición materna durante la lactancia, ¿necesitan las madres lactantes suplementos nutricionales? / The importance of maternal nutrition during breastfeeding: Do breastfeeding mothers need nutritional supplements?

La leche materna es el mejor alimento para los recién nacidos y lactantes. Las reservas nutricionales de una mujer lactante pueden estar más o menos agotadas como resultado del embarazo y la pérdida de sangre durante el parto. La lactancia plantea necesidades nutricionales especiales, principalmente debido a la pérdida de nutrientes a través de la leche materna. El volumen de leche materna varía ampliamente. Los nutrientes presentes en la leche proceden de la dieta de la madre o de sus reservas de nutrientes. Para conseguir un buen estado nutricional durante la lactancia, la mujer tiene que aumentar la ingesta de nutrientes. La leche materna tiene una composición bastante constante y la dieta de la madre solo afecta a algunos nutrientes. El contenido de grasa de la leche materna varía con la dieta. El contenido de hidratos de carbono, proteína, calcio y hierro no cambia mucho incluso si la madre ingiere poca cantidad de estos en su dieta. Sin embargo, si la dieta de una madre es deficiente en vitaminas hidrosolubles y vitaminas A y D, su leche contiene menos cantidades de estos nutrientes. En cada visita posnatal tanto la madre como el niño deben ser examinados, y se debe proporcionar asesoramiento sobre la alimentación saludable. Durante la lactancia se debe evitar una dieta que aporte menos de 1.800cal al día

Breastmilk is the best food for newborns and infants. The nutritional stores of a lactating woman may be more or less depleted as a result of the pregnancy and the loss of blood during childbirth. Lactation raises nutrient needs, mainly because of the loss of nutrients, first through colostrum and then through breastmilk. Breastmilk volume varies widely. The nutrients present in this milk come from the diet of the mother or from her nutrient reserves. The conversion of nutrients in food to nutrients in breastmilk is not complete. To have good nutritional status the breastfeeding woman has to increase nutrient intake. Human breastmilk has a fairly constant composition, and is only selectively affected by the diet of the mother. The fat content of breastmilk varies somewhat. The carbohydrate, protein, fat, calcium and iron contents do not change much, even if the mother is short of these in her diet. A mother whose diet is deficient in thiamine and vitamins A and D, however, produces less of these in her milk. The mother should be given advice on consuming a mixed diet. At each postnatal visit, both the mother and the baby should be examined, and advice on the diets of both mother and infant should be provided. A satisfactory gain in the infant's weight is the best way to judge the adequacy of the diet of the infant. Mothers should not receive less than 1800 calories per day
