RESUMO

INTRODUCCIÓN: El raquitismo carencial es una enfermedad emergente en nuestro medio y se describe especialmente en lactantes y niños inmigrantes de raza negra o piel oscura procedentes de países en vías de desarrollo. El objetivo de este trabajo está dirigido a conocer el estado nutricional de vitamina D en lactantes y niños inmigrantes de diferentes etnias de edad inferior a 6 años y compararlo con una población infantil autóctona. Población y métodos: Estudio prospectivo efectuado en un Centro de Asistencia Primaria de la localidad de Salt (Girona). Población: 307 niños con la siguiente distribución por origen y etnia: caucásicos (n=85; 28%), subsaharianos (n=101; 32,5%); magrebíes (n=87, 28,0%); centroamericanos (n=20; 6,4%) e indopakistaníes (n=14; 4,5%). Parámetros bioquímicos evaluados: calcemia, fosforemia, fosfatasa alcalina, 25-hidroxivitamina D y parathormona. Encuesta nutricional para estimar la ingesta de calcio, el aporte de vitamina D y el grado de exposición solar. RESULTADOS: Presentan déficit de vitamina D (< 20 ng/ml) el 8% de los niños de origen caucásico, el 18% de los subsaharianos, el 20% de los centroamericanos, el 34,5% de los magrebíes y el 64% de los niños de origen indopakistaní. El 2,9% de los niños estudiados (n = 9) presentan déficit grave de vitamina D (< 10 ng/ml), de los que tan solo un niño de origen subsahariano reúne criterios bioquímicos de raquitismo clásico. La prevalencia de la deficiencia de vitamina D es significativamente más elevada en los niños sin suplementación con vitamina D durante el primer año de vida. CONCLUSIONES: El 22,5% de los niños menores de 6 años de edad presenta concentraciones plasmáticas en rango deficitario de vitamina D, siendo más prevalente en los niños de origen indopakistaní y magrebí


INTRODUCTION: Nutritional rickets is an emergent disease in Spain, and occurs particularly in black and dark-skinned infants and children from immigrant populations. The aim of this work was to ascertain the vitamin D reserve in a population of native and immigrant children under the age of 6 years. Population and methods: A prospective study was conducted at a Primary Healthcare Centre in Salt (Girona). PATIENTS: 307 children with the following origin and race distribution: Caucasian (n = 85; 28%), Sub-Saharan (n = 101; 32.5%); Maghrebí (n = 87, 28.0%); Central-American (n = 20; 6.4%) and Indo-Pakistani (n = 14; 4.5%). The biochemistry blood parameters studied were: calcium, phosphorus, alkaline phosphatase, 25-hydroxivitamin D, and parathormone. A nutritional survey was used to estimate calcium and vitamin D intake and degree of sun exposure. RESULTS: Vitamin D deficiency (< 20 ng/ml) was detected in Caucasians (8%), Sub-Saharans (18%), Central-Americans (20%), Maghrebís (34.5%), and Indo-Pakistanis (64%). Of the children studied (n = 9), 2.9% had serious vitamin D deficiency (< 10 ng/ml); only one child of Sub-Saharan origin met the biochemical criteria for classical rickets. The prevalence of vitamin D deficiency was significantly higher in children not receiving vitamin D supplements in the first year of life. CONCLUSIONS: Plasma vitamin D concentrations were deficient in 22.5% of children under the age of six, being more prevalent in children of Indo-Pakistani and Maghrebí origin

RESUMO

Introducción: La alta prevalencia de ferropenia en nuestro medio, así como el número elevado de población inmigrante con hábitos y culturas alimentarias diferentes, fundamentan un estudio para evaluar el estado nutricional y documentar la presencia de ferropenias secundarias a las diversas pautas de alimentación. Objetivos: Evaluar los parámetros antropométricos y las concentraciones plasmáticas de hemoglobina, ferritina y sideremia de cada etnia. Población y métodos: Estudio prospectivo realizado durante los años 2008-2010 en una consulta de pediatría de atención primaria, en una población de 307 niños de Salt (Girona), con una edad inferior a 6 años, de diferentes etnias: caucásicos (n= 85; 27,4%), magrebíes (n= 87; 28%), subsaharianos (n= 101; 32,5%), centroamericanos (n= 20; 6,4%) e indopakistaníes (n= 14; 4,5%). Los parámetros bioquímicos estudiados fueron la hematimetría, la sideremia y la ferritina. Resultados: El análisis de los parámetros antropométricos no demuestra diferencias significativas entre la población autóctona y la inmigrante. En el análisis bioquímico se pone de manifiesto un déficit de hierro (sideremia <50 µg/dL) (caucásicos 38,5%, magrebíes 51%, subsaharianos 43%, centroamericanos 35%, indopakistaníes 79%), un déficit de ferritina (<20 ng/mL) (caucásicos 10,5%, magrebíes 49%, subsaharianos 29%, centroamericanos 15% e indopakistaníes 85%) y un déficit de hemoglobina (<10,5 mg/mL) (caucásicos 3,7%, magrebíes 7%, subsaharianos 15%, centroamericanos 5% e indopakistaníes 21%). Conclusiones: No se ha detectado desnutrición con repercusión auxológica en las poblaciones evaluadas. Pero se aprecia un déficit de hierro, ferritina y hemoglobina en las poblaciones infantiles magrebí, subsahariana y, de forma más acusada, indopakistaní (AU)


Introduction: Due to the high prevalence of ferropenic diseases and the increase of different immigrant populations with their own eating habits, a population-based study was considered necessary in order to evaluate the nutritional status and document possible iron deficiencies secondary to each food culture. Study purpose: To evaluate the anthropometric parameters, the hemoglobin and ferritin plasmatic concentrations and the sideremy values in each ethnic group. Population and methods: Prospective study carried out from 2008 to 2010, in a paediatrician consultation working area. Population: 307 children from Salt (Girona) under the age of 6, Caucasian (n= 85; 27.4%), Moroccan (n= 87; 28%), Sub-Saharan African (n= 101; 32.5%), Central American (n= 20; 6.4%) and Indian-Paquistan (n= 14; 4.5%). Biochemical parameters: blood count, sideremy and ferritin values. Results: Analysis of anthropometric parameters did not show any relevant difference between the native and the immigrant population. The biochemical data showed a sideremy deficiency (<50 µg/dL) (Caucasian population 38.5%, Moroccan 51%, Sub-Saharan African 43%, Central American 35%, Indian-Paquistan 79%), a ferritin deficiency (<20 ng/mL) (Caucasian population 10.5%, Moroccan 49%, Sub-Saharan African 29%, Central American 15%, Indian-Paquistan 85%) and an hemoglobin deficiency (<10.5 mg/mL) (Caucasian population 3.7%, Moroccan 7%, Sub-Saharan African 15%, Central American 5%, Indian-Paquistan 21%). Conclusions: No auxologic malnutrition was detected in the studied population; however, there was a clear deficiency in sideremy, ferritin and hemoglobin in the child populations from Morocco and Sub-Saharan Africa, this being even more evident among the Indian-Paquistan population (AU)

RESUMO

INTRODUCTION: Gestational age and neonatal anthropometric parameters are related to neonatal and postnatal morbidity and mortality. SUBJECTS AND METHODS: Weight and vertex-heel length were evaluated in 9.362 caucasian newborns (4.884 males and 4.478 females) products of single pregnancies, 26-42 weeks of gestational age, born between 1999 and 2002 in Vall d'Hebron (Barcelona, Spain) and Miguel Servet (Zaragoza, Spain) Children's Hospitals. RESULTS: Mean and standard deviation and percentile distribution values of weight, and length according to sex and gestational age are presented. A progressive increase in these parameters with gestational age and a sexual dimorphism was observed from the 30 week of gestational age onwards, with statistically-significant differences (p<0.01) from 35 weeks of gestational age. At 38 and 42 weeks of gestational ages these differences were 170 g, 160 g, 0.8 cm and 0.9 cm respectively. An increase in weight and length values in relation to previous Spanish studies (1987-1992) was also documented. CONCLUSIONS: A sexual dimorphism in intrauterine anthropometric growth parameters was observed. These parameters change with time and may be updated.

RESUMO

INTRODUCTION: In developed countries a secular trend in growth has been reported. Our aim was to evaluate weight, height and body mass index (BMI) values in a Spanish population coming from Andalusia, Barcelona, Bilbao and Zaragoza, and to compare these values with those obtained before 1988 (BIB 88 and CAT 87 studies). SUBJECTS AND METHODS: Cross-sectional evaluation of height, weight and BMI in 32,064 subjects (16,607 males and 15,457 females) from birth to adulthood between the years 2000 and 2004. Three subpopulations were evaluated: a) 5,796 (2,974 males, 2,822 females) newborns at term from normal gestations; b) 23,701 (12,358 males; 11,343 females) children and adolescents 0.25-18 years old, and c) 2,567 (1,275 males, 1,292 females) young adults 18.1-24 years of age. All were healthy caucasians, and their parents from Spanish origin. The LSM method was used. RESULTS: Mean, standard deviation, Skewness index and percentiles values with a 0.25-0.5 year-period intervals from birth to adulthood are reported. As regards the data obtained previously in Spanish populations, an increase of 1.8 cm, 1.4 cm and 3.3 cm were observed in adult height for percentiles 3, 50 and 97 in males respect to BIB 88 and 2.5 cm, 3.3 cm and 3.8 respect to CAT 87. In females these values were 3.5 cm, 2.5 cm and 4.2 cm respect to BIB 88 and 3.5 cm, 3.1 cm and 3.9 cm respect to CAT 87. The corresponding values for weight, in males, were increased in 5.4 kg, 6.2 kg and 11.7 kg respect to BIB 88 and 6.7 kg, 6.3 kg and 10.1 kg respect to CAT 87; in females these increased were 1.7 kg, 2,2 kg and 8.3 kg respect to BIB 88 and 1.8 kg, 2.4 kg and 3.6 kg respect to CAT 87. The corresponding increased for BMI values, in males, were 2.0, 1.4 and 3.9 respect to BIB 88 and 0.1, 0.2 and 5.3 respect to CAT 87; in females these values were 0.9, 0.4 and 3.7 respect to BIB 88 and 1.8, 0.1 and 4 respect to CAT 87. In young adults, 25 and 30 BMI values correspond to percentiles 80 and 97 in males, and 85 and 97 in females. Mean values of adult height were similar to those observed in other longitudinal and cross-sectional Spanish, European, and American studies, but lower than those reported for German, Swedish and Netherlands populations. CONCLUSIONS: A secular trend of growth was observed in our population with a non-proportional increased of weight to height ratio (BMI) values, particularly for those corresponding to the 97 percentile. The need of periodical updates of growth data used in the evaluation of children and adolescents is required.

RESUMO

Introducción: La edad gestacional, el peso y la longitud al nacer son factores relacionados con la morbilidad y mortalidad en el período neonatal y en la vida adulta. Sujetos y métodos: Valoración del peso y la longitud vértice-talón al nacer, en 9.362 recién nacidos vivos de raza caucásica (4.884 varones y 4.478 niñas) y de gestaciones únicas (26-42 semanas de edad gestacional), nacidos entre 1999 y 2002 en el Hospital Materno-Infantil Vall d’Hebron de Barcelona y en el Hospital Materno-Infantil Miguel Servet de Zaragoza. Resultados: Valores de la media y desviación estándar, y distribución percentilada del peso y de la longitud en los recién nacidos de ambos sexos según su edad gestacional. Existe un incremento progresivo con la edad gestacional y un dimorfismo sexual a partir de la semana 30 de gestación con diferencias estadísticamente significativas entre ambos sexos para ambos parámetros (p < 0,01) a partir de la semana 35 de edad gestacional. A las 38 y 42 semanas de edad gestacional los valores de la media para el peso y para la longitud son, respectivamente, 170 y 160 g, y 0,8 y 0,9 cm superiores en los varones que en las niñas. También se observó un incremento en los valores de la media de peso y longitud respecto a estudios previos (1987-1992). Conclusiones: Existe un dimorfismo sexual en el peso y la longitud de los recién nacidos pretérmino y a término. Estos parámetros cambian con el tiempo y deben ser revisados periódicamente (AU)

RESUMO

Introducción: En las sociedades desarrolladas existe una aceleración secular del crecimiento. Entre los años 2000 y 2004 hemos valorado el crecimiento en una población caucásica española procedente de Andalucía, Barcelona, Bilbao y Zaragoza y hemos comparado los resultados con estudios españoles realizados antes de 1988 en poblaciones caucásicas de Bilbao (BIB 88) y Cataluña (CAT 87). Sujetos y métodos: Estudio transversal que valora el peso, la longitud y el índice de masa corporal (IMC) en 32.064 sujetos (16.607 varones y 15.457 mujeres) desde el nacimiento a la talla adulta: a) 5.796 son recién nacidos a término (2.974 varones y 2.822 mujeres) hijos de madres sanas, de gestaciones únicas; b) 23.701 son niños y adolescentes (12.358 varones y 11.343 mujeres) de 0,25 a 18 años de edad ambos inclusive, y c) 2.567 son adultos jóvenes (1.275 varones y 1.292 mujeres) de 18,1 a 24 años de edad. Todos estaban sanos, eran de raza caucásica y sus padres, de origen español. La distribución percentilada, el valor z-score y el diseño de las gráficas se ha realizado según el método LMS. Resultados: Se expresan los valores de la media, desviación estándar, coeficiente de Skewness y percentiles desde el nacimiento a la edad adulta, en intervalos de 0,25-0,50 años. Existe un dimorfismo sexual y un incremento en los valores de peso y talla de todos los percentiles respecto a los estudios BIB 88 y CAT 87. Los valores de los percentiles 3, 50 y 97 de la talla adulta son superiores en 1,8, 1,4 y 3,3 cm respecto a BIB 88, y en 2,5, 3,3 y 3,8 cm respecto a CAT 87 en los varones, y 3,5, 2,5 y 4,2 cm respecto a BIB 88 y 3,5, 3,1 y 3,9 cm respecto a CAT 87 en las mujeres. Los correspondientes valores de peso son 5,4, 6,2 y 11,7 kg superiores a los de BIB 88 y 6,7, 6,3 y 10,1 kg superiores a los de CAT 87 en los varones y 1,7, 2,2 y 8,3 kg superiores a los de BIB 88, y 1,8, 2,4 y 3,6 kg superiores CAT 87 en las mujeres. Los respectivos incrementos en el IMC son 2,0, 1,4 y 3,9 respecto a BIB 88 y –0,1, –0,2 y 5,3 respecto a CAT 87 en los varones y 0,9, 0,4 y 3,7 respecto a BIB 88 y –1,8, –0,1 y 4,0 respecto a CAT 87, en las mujeres. Los valores del IMC de 25 y 30 “en la edad adulta” corresponden a los percentiles 80 y 97 en los varones y 85 y 97 en las mujeres. En ambos sexos los valores de la talla media adulta son similares a los observados en otros estudios longitudinales y transversales españoles recientes y a los observados en estudios europeos y americanos, aunque inferiores a los de la población alemana, sueca y holandesa. Conclusiones: Con relación a estudios españoles previos, existe una aceleración secular de peso y talla, con un incremento desproporcionado en los valores del IMC correspondientes al percentil 75 o superiores, y de forma marcada en los del percentil 97. Este estudio muestra la necesidad de actualizar periódicamente los datos de referencia utilizados en la valoración del crecimiento durante la infancia y adolescencia (AU)

RESUMO

Patients with type 1 diabetes and poor metabolic control can develop hepatomegaly due to intrahepatic glycogen deposition. If these patients also have elevated liver enzymes, dyslipidemia, cushingoid features and delayed growth or sexual maturation, Mauriac syndrome can be diagnosed. This disorder is common and reversible with optimization of insulin therapy. We report three adolescents with type 1 diabetes and a long-standing history of poor glycemic control, who developed hepatomegaly, elevated liver enzymes and dyslipidemia with preserved liver function. One of these patients also had delayed growth and another had hypogonadotropic hypogonadism. Liver ultrasound showed changes suggestive of glycogenosis. In all three patients, optimization of insulin therapy achieved good glycemic control and reversed the manifestations within 2 weeks. The etiology of Mauriac syndrome is controversial since both prolonged hyperglycemia and hyperinsulinization produce glycogen accumulation in the liver. Hypercortisolism (due to ketosis or hypoglycemia) contributes to glycogen storage and also causes growth and sexual maturation delay.

RESUMO

Los pacientes diabéticos tipo 1 con mal control metabólico pueden desarrollar hepatomegalia secundaria al depósito de glucógeno intrahepático. Si además presentan hipertransaminasemia, dislipemia, rasgos cushingoides, y retraso del crecimiento y del desarrollo puberal podemos hablar de síndrome de Mauriac. Este síndrome es frecuente y reversible con la optimización del tratamiento insulínico. Presentamos 3 adolescentes diabéticos tipo 1 de larga evolución con mal control metabólico que manifestaron hepatomegalia, hipertransaminasemia y dislipemia con funcionalismo hepático normal. Uno de ellos presentó retraso de crecimiento y otro hipogonadismo hipogonadotropo. Las ecografías hepáticas mostraron glucogenosis. El cuadro revirtió en todos ellos con la optimización de la insulinoterapia manteniendo controles glucémicos normales en el plazo de 2 semanas. La etiología del síndrome Mauriac es controvertida pues tanto la hiperglucemia mantenida como la hiperinsulinización producen glucogenosis. La hipercortisolemia también (fruto de la cetosis o hipoglucemia) y además produce retraso de crecimiento y del desarrollo puberal

RESUMO

Glycogen storage diseases are a rare group of disorders in daily pediatric practice but must be taken into account when a patient presents with poor physical growth, hepatomegaly, hypoglycemia, hypotonia and/or other metabolic disturbances. Early diagnosis allows treatment that might improve the patient's outcome to be started or, at the very least, genetic counseling to be given to the parents. We present a 10-month-old boy who presented with growth retardation, abdominal distention and hepatomegaly and who was finally diagnosed with glycogenosis type IX. Definitive diagnosis was obtained by demonstrating the enzyme defect (phosphorylase beta-kinase) in affected tissues. Enteral nutrition was started using a diurnal high-carbohydrate diet with frequent feedings and nocturnal nasogastric continuous feeding, achieving optimal growth parameters and clinical response.

RESUMO

Las glucogenosis son entidades poco frecuentes en la práctica diaria de un pediatra, pero deben tenerse en cuenta ante todo paciente que se presente con retraso del crecimiento, hepatomegalia, hipoglucemia, alteración del tono muscular y/o alteraciones en el estudio metabólico. La importancia de su diagnóstico precoz puede permitir iniciar un tratamiento con el cual poder mejorar el pronóstico del paciente o, en el peor de los casos, ofrecer a la familia un consejo genético adecuado. Se comenta el caso de un lactante de sexo masculino de 10 meses de edad que presentaba un cuadro de estancamiento ponderal, distensión abdominal y hepatomegalia. El diagnóstico de glucogenosis tipo IX se confirmó mediante la demostración de la ausencia de actividad enzimática de la fosforilasa -cinasa, enzima alterada en esta entidad. Se inició alimentación enteral mediante gastroclisis continua nocturna y dieta diurna rica en hidratos de carbono con buena respuesta clínica y recuperación de los parámetros somatométricos (AU)

RESUMO

Biliary atresia (BA) is the most common indication for liver transplantation in children. Approximately 7-10% of these patients have the associated polysplenia syndrome (PS). The prognosis of patients with BA and PS has been reported to be poorer than that in patients with BA without PS. All patients who underwent liver transplantation for BA and who still attend periodic controls at the outpatient clinic were considered. A retrospective study of outcome and growth in children with BA was made, and compared with a subgroup of patients with BA and PS. There were no significant differences on complications, liver and renal function tests, lipids and growth data. We concluded that BA and PS do not preclude successful liver transplantation.

RESUMO

Los defectos de la síntesis de tiroglobulina son una causa poco frecuente de hipotiroidismo congénito. El diagnóstico neonatal de esta entidad puede escapar a los programas de screening por la existencia de niveles normales de hormonas tiroideas y discretamente elevados de TSH. Se presenta el caso clínico de una niña que consulta a los 14 años por bocio muy voluminoso (grado 3) y disfagia a sólidos. El estudio de la función tiroidea mostró concentraciones muy bajas de tiroglobulina y de T4, valores normales de T3 y elevación moderada de los niveles de TSH, hipercaptación tiroidea y respuesta negativa al test de descarga de perclorato. El screening neonatal para hipotiroidismo congénito fue negativo. Se diagnostica a los 3 años de hipotiroidismo por bocio difuso (grado lb). No recibió tratamiento sustitutivo con hormona tiroidea por decisión familiar, Siguiendo tratamiento naturalista con aminoácido 1-tirosina, zinc y Suplementos vitamínicos. El desarrollo pondoestatural y psicomotor fue normal. En resumen, el desarrollo precoz de bocio en niños con screening neonatal normal y en estado de eutiroidismo debe hacernos sospechar la existencia de una dishormonogenesis, y entre ellas la producida por defecto de la síntesis y secreción de tiroglobulina (AU)
