El colecho favorece la práctica de la lactancia materna y no aumenta el riesgo de muerte súbita del lactante. Dormir con los padres / Bed-sharing favours the practice of breastfeeding and does not increase the risk of sudden infant death syndrome. Sleeping with parents

La práctica de los padres de dormir junto a sus hijos ha sido una constante en la humanidad. Con el aumento en la prevalencia y duración de la lactancia materna, se ha observado paralelamente un aumento de esa práctica, que posiblemente se dé con más frecuencia que la reconocida en las encuestas. Los estudios han demostrado interrelación y mutua potenciación entre lactancia materna y colecho. Las asociaciones y organizaciones pediátricas recomiendan evitar el colecho, por relacionarlo con la muerte súbita del lactante. Se basan, sin embargo, en estudios en su mayoría no controlados, bajo la influencia de factores de riesgo no tenidos en cuenta. Los autores, tras una revisión exhaustiva sobre colecho, lactancia y muerte súbita del lactante, encuentran el colecho como una práctica beneficiosa para la lactancia y concluyen que, bien practicado, evitando factores de riesgo, no guarda relación con la muerte súbita del lactante (AU)

The practice of bed-sharing by parents and their offspring has been a common behaviour among humans. In parallel with the increase of breastfeeding rates, a higher frequency of bed-sharing has been observed worldwide. And, it is probable that it occurs more frequently than what appears reflected in surveys. There seems to be an interrelated and mutually enhanced effect between breastfeeding and bed-sharing. Pediatric associations and health organizations have warned against the practice of bed-sharing based on studies that describe a link between this practice and Sudden Infant Death Syndrome (SIDS). However, many were non-controlled studies that did not include other potentially risky circumstances. After a thoroughly review of the available literature, the authors have found the practice of bed-sharing to be of benefit on the basis of a warm and close-up infant care approach and calls for recognition and avoidance of risky situations that could represent a threat for infant life (AU)

Uso del chupete y lactancia materna / Use of pacifiers and breastfeeding

El uso del chupete se encuentra muy arraigado en las sociedades desarrolladas, ya que calma el llanto del bebé, ayuda a conciliar el sueño, y reduce el estrés y el dolor en procedimientos desagradables. Su uso se ha relacionado con una menor duración y exclusividad de la lactancia materna, aumento de otitis media, problemas dentales y riesgo de accidentes. Además, estudios recientes relacionan su uso, particularmente durante el sueño, con disminución del riesgo de muerte súbita del lactante. Otros beneficios demostrados son su efecto analgésico y el estímulo de la succión no nutritiva en niños pretérmino y a término. El debate sobre su utilización o no es actualmente motivo de controversia, pero es importante que los profesionales de la salud y los padres conozcan los riesgos y beneficios que conlleva el uso del chupete. Dada la controversia actual, el Comité de Lactancia Materna de la Asociación Española de Pediatría ha realizado, a la luz de las pruebas disponibles actualmente, una revisión del tema en relación con la lactancia materna (AU)

Pacifiers are widely used in developed societies. They are used for soothing infants, reducing their stress and pain during procedures and to help them sleep. The use of pacifiers has been associated, however, with a shorter duration and exclusivity of breastfeeding, with higher rates of otitis media and dental problems, as well as a higher risk of accidents during infancy. Recent studies have also described a relationship between pacifier use and SIDS, especially when used during infant is sleep. Other described benefits are analgesia and stimulation of non-nutritive sucking in preterm and term infants. There is, at present, wide debate and controversy on whether or not to recommend its use; thus it seems important for professionals and parents to be aware of the risks and benefits associated to its use, particularly related to breast feeding. Due to the existing controversy of scientific findings, the Committee on Breastfeeding of the Spanish Paediatrics Society, publishes this review, trying to summarise present evidence with the objective of, after analysing scientific results and recommendations, making recommendations regarding the use of the pacifier in the breastfed infant (AU)

Enfermedades frecuentes del tiroides en la infancia / No disponible

La aparición de alteraciones de la función tiroidea en los niños es muy frecuente. Parece que hay datos suficientes para asegurar que el seguimiento de las hormonas tiroideas, al menos durante la infancia, es muy útil para evitar posibles problemas a largo plazo. Por tanto, cualquier beneficio potencial sería mayor que los posibles efectos dañinos. En los controles de salud de los niños, siempre debe investigarse la presencia de signos de sospecha de disfunción endocrinológica. En esta especialidad tan vinculada a los procesos de crecimiento y desarrollo, donde los signos de casi todas sus patologías son muy discretos en su comienzo, debe agudizarse al máximo la observación, ya que es importante el diagnóstico precoz para que los tratamientos resulten eficaces y puedan evitar las secuelas de la enfermedad. Solo si se investiga, la mayoría de las enfermedades endocrinológicas pueden ser descubiertas tempranamente. Únicamente el pediatra puede contribuir al diagnóstico precoz. La interpretación de normalidad/anormalidad del proceso de crecimiento y desarrollo del niño, es una herramienta de gran utilidad durante la infancia. En la etapa de estudio, así como en la de tratamiento, una vez confirmada la enfermedad, el pediatra debe integrar el equipo ampliado de atención del niño. El pediatra por su parte, en estrecha comunicación con el grupo especializado, conducirá a la familia y al paciente en su nueva condición de enfermo crónico(AU)

The appearance of alterations of the thyroid function in children is very frequent. It seems that there are sufficient data to assure that the control of thyroid function during childhood is at least very useful in order to avoid possible problems in the long-term development. Therefore, any potential benefit would be greater than the possible harmful effects. In the controls of the well child, the signs of suspicion of endocrinologic disfunción must be investigated always. In the processes of growth and development, where the signs of almost all their impairments are very discreet in their beginning, the observation must become thorough since early diagnosis is important for the treatments to be effective and to be able to avoid the sequels of the disease. Pediatricians have an important contribution to the early diagnosis. The interpretation of normality/abnormality of the process of growth and development of the infant, is a very useful tool during childhood. In the stage of study as well as in the treatment, pediatricians must integrate the extended team of childcare. Pediatricians will lead the family and the patient in its new condition of chronic patient(AU)

Deficiencia de yodo y prematuridad / Iodine deficiency and prematurity

El yodo es un oligoelemento esencial para la síntesis de hormonas tiroideas. La deficiencia de este oligoelemento es especialmente preocupante en el recién nacido, que debe sintetizar suficientes hormonas tiroideas para hacer frente a sus necesidades hormonales, ya que los preparados para alimentación de neonatos a término y prematuros no siempre contienen el yodo necesario. En el mundo, la mayor causa dehipotiroxinemia es la deficiencia de yodo, la cual está reconocida como la causa más importante de retraso mental y parálisis cerebral prevenible (AU)

Iodine is a trace element essential for the synthesis of thyroid hormones. Iodine deficiency is especially worrying inneonates, who must synthesize sufficient thyroid hormones to meet their hormonal requirements, since formula preparations for premature and term infants do not always contain adequate iodine. Worldwide, the main cause of hypothyroxinemia is iodine deficiency, which in turn is the main preventable cause of mental retardation and cerebral palsy(AU)

[Thyroid function alterations in children with congenital cardiac disease after catheterization with iodinated contrast agents]. / Alteraciones de la función tiroidea en niños con cardiopatía congénita tras la realización de cateterismo con contrastes yodados.

INTRODUCTION AND OBJECTIVES: Iodinated contrast agents can block thyroid hormone synthesis. The aims of this study were: 1st) to study the incidence of thyroid function disturbances in children with congenital heart disease after cardiac catheterization, 2nd) to analyze the predisposing factors that may lead to the development of hypothyroidism after angiography, and 3rd) to determine the duration of these hypothyroidism states. PATIENTS AND METHODS: From february 1993 to April 1997 thyrotropine (TSH) and free thyroxine (FT4) serum values were analyzed before cardiac catheterization and in the two following weeks, in 99 children under three years of age, with congenital cardiac disease. Those patients who showed any postangiography increase in TSH were further evaluated by weekly measures of serum thyroid hormones and TSH until normal values were obtained or until the initiation of hormonal replacement therapy. The patients' data (age, previous exposure to contrast agents, cardiac disease, associated extracardiac malformations, renal failure, severity of illness, treatment) and the catheterism data (the dose and type of contrast and the fluoroscopy time) were included in the univariant analysis. RESULTS: 10 mUI/ml), that persisted beyond three weeks in six cases. The occurrence of multiple malformation syndromes was the most clearly associated risk factor (p < 0,01) not only in the development of postangiography hypothyroidism but also in longer hormonal dysfunction. CONCLUSIONS: Thyroid function should be tested in every patient with multiple malformation syndrome that undergo angiocardiography with iodinated contrast agents.
