RESUMO

Objetivo: El objetivo de este estudio ha sido analizar si existe correlación entre el índice da masa corporal (IMC) de los niños con obesidad con los parámetros antropométricos familiares, hábitos de vida y parámetros bioquímicos. Pacientes: niños entre 2-17 años .Todos los pacientes y sus padres rellenaron encuestas donde se recogieron datos personales y habitos de vida. Resultados: Participaron en el estudio 108 niños con obesidad 44,4% niños. Edad media de 10 años (2-17 años). El 56% prepuberales. El IMC medio de 27,8 % (+4,4DS). No encontramos correlación entre el IMC del niño y el nivel de estudios familiar ni con la situación laboral familiar, ni con quién le acompaña por las tardes. Sólo el 4,6% obtienen una puntuación < 3, en calidad de la dieta (KIDMED). Los niños dedican 3,3 horas al día a actividades sedentarias. Se encontró correlación entre el nº total de actividades sedentarias y el IMC del niño (r=0,205;p=0,004). También el peso con IMC de los progenitores(r= 0,427;P<0,001).Solo se correlacionan con el IMC la insulina, péptido C y índice HOMA, por encima de los valores normales. Conclusiones: La actividad sedentaria es uno de los parámetros fundamentales en el desarrollo de la obesidad. Dada la relación del IMC, la insulinemia y el índice HOMA, y teniendo en cuenta que estos valores están por encima de los valores normales, el mantenimiento de esta situación en el tiempo, podría ser el responsable del síndrome metabólico en el adulto (AU)


Objetive: The objective of this study has been to analyze if there is correlation between the body mass index (BMI) of children with obesity with the anthropometric parameters of their relatives and habits of life. Patients: children between 2-17 years of age. All the patients and their parents filled up a survey where they gathered data on anthropometry, and life style. Results: 108 children participated in the study. 44,4% boys. Average age of 10 years (2-17 years). 56% prepubertal. BMI means of 27,8% (+4,4DS). We didn´t found any correlation between the BMI of the child and the familiar level of studies neither with their labor situation. Only 4,6% obtain a score < 3, in quality of the diet (KIDMED). The children dedicate 3.3 hours of the day to sedentary activities. There was correlation between total nº of sedentary activities and the BMI of the boy (r=0,205; p=0,004), and the weight with BMI of the ancestors (r= 0,427; P< 0,001) too. Insulin, peptide C and index HOMA are correlated with BMI, these values are over the normal range. Conclusions: Sedentary activity is one of the fundamental parameters in the development of the obesity. Given the relation between BMI, insulinemia and index HOMA, and considering that these values are upon the normal values, the maintenance of this situation in time, could be the responsible of the metabolic syndrome in the adult (AU)

RESUMO

Objetivo: El objetivo de este estudio es analizar la secuencia de la pubertad en los niños y las niñas de nuestra área sanitaria. Métodología: Trescientos diez niños y niñas sanos de raza caucásica participaron en este estudio prospectivo. Se recogieron las siguientes variables: peso de recién nacido (PRN), peso (kg), talla (cm) e índice de masa corporal (IMC) (%) en los diferentes estadios puberales, edad ósea al inicio y final de la pubertad el tiempo de duración de la pubertad y el crecimiento durante el mismo. Resultados: Media (DE): la pubertad se inicia en los niños a los 12,4 años (1,5) con edad ósea de 11,9 años (1,3) y se alcanza el Tanner V a los 15,6 años (1,5) con edad ósea de 14,5 años. En las niñas la pubertad empieza a los 10,1 años (1,4) con edad ósea de 10,3 años (1,1), y la menarquia a los 12,0 años (1,3) con edad ósea: de 13,2 años (0,9). El tiempo de crecimiento hasta el Tanner V en los niños es de 3 años (1,2) con un crecimiento total de 19,5cm (7,6) En las niñas el tiempo de pubertad hasta la menarquia es de 2,5 años (1,1) con un crecimiento total de 15,7cm (5,0). Los niños que comenzaron la pubertad antes de los 11 años mostraron un crecimiento mayor durante la misma 27,3cm (7,9) que los que lo iniciaron después 17,4cm (5,9) (p<0,0001) y crecieron durante más tiempo 3,9 años (1,2) versus 2,7 (1,1) (p<0,001). De igual forma las niñas que comenzaron la pubertad antes de los 9 años crecieron más 19,7cm (4,3) que las que lo hicieron después 14,4cm (4,5) (p<0,0001) y más tiempo 3,1 años (0,8) versus 2,3(0,9) (p<0,0001). Conclusión: Los niños inician la pubertad a edades similares que otras poblaciones españolas, sin embargo en las niñas se adelanta, así como la menarquia. La edad ósea es acorde a la edad cronológica en ambos sexos al inicio de la pubertad pero no al final, adelantándose en las niñas. La duración de la pubertad y el crecimiento durante la misma es mayor en aquellos que inician la pubertad antes, para ambos sexos. No se encontró ninguna relación entre el IMC y el PRN con el inicio de la pubertad (AU)


Objective: Changes in the onset of puberty have been reported in the last few years. The aim of this study is to determine pubertal trends in boys and girls. Method: Longitudinal study was conducted on 310 caucasian children. We analysed birth weight (BW), weight (kg), height (cm) and body mass index (BMI) (%), bone age, duration of puberty growth and pubertal height spurt. Results: For boys the mean age at stage 2 was 12.4 (1.5) years with a bone age of 11.9 (1.3) years, and stage 5: 15.6 (1.5) with a bone age of 14.5. Mean age (years) (SD) for girls stage 2 was 10.1 (1.4), with a bone age of 10.3 (1.1). Age at menarche was 12.0 (1.3), with a bone age of 13.2 (0.9). Duration of puberty growth for boys was 3 years (1.2), and for girls 2.5 years (1.1). Pubertal height spurt in boys was 19.5cm (7.6) and for girls was 15.7cm (5.0). Girls with puberty onset<9 years of age show a greater pubertal height gain (19.7cm (4.3)) than girls >9 years of age [14.4 (4.5) (P<0.0001)] and a longer period of pubertal growth 3.1 years (0.8) versus 2.3 (0.9) (P<0.0001). Boys with puberty onset <11 years of age had a greater pubertal height gain [27.3cm (7.9)] than boys > 11 years of age [17.4 (5.9) (P<0.0001)] and a longer period of puberty growth of 3.9 years (1.2) versus 2.7 (1.1) (P<0.001). Conclusions: Boys presented secondary sex characteristics at the same age as other studies, but the girls reached puberty and menarche at a younger age than previous studies in the Mediterranean area. Bone age correlates with chronological age for both sexes at the beginning of puberty but not at the end. Early onset of puberty was associated with a greater pubertal height gain and a longer period of pubertal growth. There was no correlation between BW or BMI with onset of puberty (AU)

RESUMO

Introducción y objetivo: En los últimos años el aumento de la incidencia de diabetes mellitus tipo 1 (DM1) se ha relacionado con un incremento de la obesidad en la población infantil, entre otros factores. El objetivo del presente trabajo ha sido determinar de forma retrospectiva en la población española, en pacientes diagnosticados de DM1 de la Comunidad Autónoma de Madrid, la posible relación entre el peso del recién nacido, el incremento del índice de la masa corporal (IMC) en los 2 primeros años de vida y el IMC al comienzo de la enfermedad con la edad de presentación de la diabetes. Material y método: Participaron 100 niños diagnosticados de DM1 de ambos sexos (57 niños y 43 niñas), de raza caucásica, con una edad media de 84,45 meses (desviación estándar [DE] de 52,4). Se recogieron las siguientes variables: edad al comienzo de la enfermedad, edad gestacional, peso y talla de recién nacido, a los 2 años de vida y al comienzo de la enfermedad. Resultados: Los niños diagnosticados de DM1 tienen menor peso al nacer −0,288 (−0,51 a −0,066) y menor IMC (puntuación de DE) al nacer que la población sana −0,5 (−0,77 a −0,23). Además de un incremento mayor del IMC hasta los 2 años (4,58% frente a 2,17%; p<0,001). Los niños con menor IMC al nacer (12,77% frente a 13,06%; p<0,006) comienzan antes con la enfermedad. No se ha encontrado correlación entre el IMC al comienzo y el resto de las variables estudiadas. Conclusiones: El menor IMC al nacer de los pacientes con diabetes mellitus estudiados y el incremento de peso que se produce en los 2 primeros años de vida en esta población podría implicar a algunos factores durante la vida fetal como factor de riesgo de DM1 (AU)


Introduction and aim: Over recent years, the increasing incidence of type 1 diabetes mellitus (T1DM) has been associated with different factors, particularly increased obesity in childhood. The aim of this study was to find out if there was any relationship between birth weight, body mass index (BMI) increase during the first two 3 years of life, and BMI at diabetes onset with age at diagnosis, in a cohort of children diagnosed with T1DM. Material and method: Data from 100 Caucasian children with T1DM of both sexes (57 boys, 43 girls) between 10 months and 16 years of age, mean age 84.45 months (SD; 52.4), were studied. We analysed the following variables: age at diagnosis, gestational age, weight and height at birth, at two years of age and at diabetes diagnosis, expressed as SD scores (SDS). Results: All children were between 38–40 weeks of gestational age. Diabetic patients have lower birth weight (−2.88 ((−0.51)–(−0.066)) and lower BMI at birth compared with healthy children −0.5 ((−0.77)–(−0.23)). Diabetic children have a significant increase in BMI during the first two years of life (4.58 versus 2.17; P<0.001). Children with the lowest BMI at birth (12.77 versus 13.06; P<0.006) are the youngest at onset of the disease. BMI at diagnosis was not related to any of the variables studied. There were no gender differences either. Conclusions: The low BMI at birth and the later increase in the following years of life seem to be related to intrauterine environment as a risk factor for T1DM (AU)

RESUMO

INTRODUCTION: In 2005 a new respiratory virus, called human bocavirus (HBoV), was cloned from respiratory samples from Swedish infants and children with lower respiratory tract infections. OBJECTIVES: To determine whether HBoV has circulated in Spain, estimate the frequency of HBoV infections in patients hospitalized for respiratory infection and describe the clinical and epidemiological characteristics of these patients. PATIENTS AND METHODS: We performed a descriptive prospective study of confirmed HBoV infections in patients aged < 14 years old, hospitalized for respiratory infections between October 2004 and June 2005. Virologic diagnosis was based on multiple RT-PCR for respiratory syncytial virus (RSV) A and B, influenza A,B, and C, parainfluenza 1-4, adenovirus and rhinovirus; PCR was used for human metapneumovirus (hMPV) and PCR in nasopharyngeal aspirates was used for HBoV. The clinical and epidemiological characteristics of patients were analyzed. RESULTS: Fifty-two cases of HBoV infection were detected, representing 17.1% (95% CI: 13% a 21%) of patients hospitalized for respiratory infections. HBoV was the third most frequent viral agent after RSV (30%) and rhinovirus (25%). In 39 patients (71.1%) coinfection with another respiratory virus was detected. Fifty percent of the patients were aged less than 13.6 months and 75% were aged less than 2 years. The most frequent diagnoses were recurrent wheezing (55.8%), bronchiolitis (21.2%) and pneumonia (15.4%). Clinical sepsis with petechial exanthema was found in two patients. Fever > 38 degrees C was found in 72.1% and radiological infiltrate in 44%. Hypoxia was present in 55.8 % of the patients. HBoV was isolated in distinct episodes in two patients. Coinfections were similar to simple infections except that hypoxia was more frequent in the former (p = 0.038). CONCLUSIONS: HBoV is one of the most frequent viruses in severe respiratory infections in patients aged less than 14 years old. Only RSV and rhinovirus are more frequent. Coinfections are highly frequent. Most patients are infants with recurrent wheezing and bronchiolitis.

RESUMO

Introducción En el año 2005 se ha clonado un nuevo virus respiratorio, llamado bocavirus humano (HBoV) de muestras respiratorias procedentes de lactantes y niños suecos con infección respiratoria de vías bajas. Objetivos Determinar si HBoV ha circulado en España, estimar la frecuencia de infecciones por HBoV en los niños hospitalizados por infección respiratoria y describir sus características clínicas y epidemiológicas. Pacientes y métodos Estudio descriptivo, prospectivo de las infecciones confirmadas por HBoV en niños menores de 14 años, hospitalizados por infección respiratoria desde octubre de 2004 a junio de 2005. Para el diagnóstico virológico se realizó reacción en cadena de la polimerasa-transcripción inversa (RT-PCR) múltiple para virus respiratorio sincitial (VRS) A y B, influenza A, B y C, parainfluenza 1-4, adenovirus y rinovirus; PCR para metapneumovirus humano (hMPV) y PCR para HBoV en aspirado nasofaríngeo. Se describen las características clínicas y epidemiológicas de los pacientes. Resultados Se detectaron 52 casos de infección por HBoV, lo que supuso el 17,1 % (IC [intervalo de confianza] 95 %: 13 a 21) de los pacientes hospitalizados por procesos respiratorios. HBoV fue el tercer agente viral tras el VRS (30 %) y el rinovirus (25 %). En 39 casos (71,1 %) se detectó coinfección con otro virus respiratorio. El 50 % de los pacientes eran menores de 13,6 meses y el 75% menores de 2 años. Los diagnósticos más frecuentes fueron sibilancias recurrentes (55,8 %), bronquiolitis (21,2 %) y neumonía (15,4 %). Dos niños presentaron sepsis clínica con exantema petequial. El 71,2 % presentó fiebre superior a 38 °C e infiltrado radiológico el 44 %. Presentaron hipoxia el 55,8 % de los niños. Dos pacientes presentaron aislamientos positivos para HBoV en distintos episodios. Las coinfecciones fueron similares a las infecciones simples, excepto que presentaron hipoxia con más frecuencia, p = 0,038. Conclusiones HBoV es uno de los virus más frecuentes en las infecciones respiratorias graves de los niños, sólo precedido por VRS y rinovirus. Las coinfecciones son muy frecuentes. La mayoría de los niños son lactantes con sibilancias recurrentes y bronquiolitis

RESUMO

OBJECTIVE: The aim of this study was to establish the reference values of the Homeostasis Model Assessment (HOMA) and Quantitative Insulin Sensitivity Check (QUICKI) indexes, as well as those of insulin and C-peptide levels in healthy children and adolescents with a view to determining reference percentiles to detect those at cardiovascular risk. MATERIAL AND METHODS: A total of 372 children boys and girls of different ages and at distinct pubertal stages with normal body mass index participated in the study. Fasting glucose, insulin and C-peptide values were measured by chemiluminescence and the HOMA and QUICKI indexes were calculated. RESULTS: Fasting glucose levels were normal in all children. The mean values obtained for each variable were (mean (SD)): fasting glucose 87(7.75) mg/dL, insulin 7.74 (5.35) microU/mL, C-peptide: 1.76 (0.79) ng/mL, HOMA index 1.72 (1.27) and QUICKI index 0.72 (0.29). All the variables progressively increased with age, with statistically significant differences between prepubertal and pubertal children. The QUICKI index showed an inverse relationship. In addition, significant differences were found between sexes. The 90th percentile for all the variables was as follows: insulin 15.05 microU/mL, C-peptide: 2.85 ng/mL, HOMA index 3.43 and QUICKI index 1.10. CONCLUSIONS: Values of fasting glucose, insulin, C-peptide and the HOMA index significantly increased with age and pubertal stage, while the QUICKI index decreased. We defined the 90th percentile for all the parameters studied as the cut-off point to identify children at cardiovascular risk in our population.

RESUMO

Objetivo: El objetivo de este trabajo ha sido establecer los valores de referencia de los índices Homeostasis Model Assessment (HOMA) y Quantitative Insulin Sensitivity Check Index (QUICKI), insulina y péptido C en ayunas en niños sanos, y con ello obtener percentiles de referencia a partir de los cuales establecer un punto de corte para valorar el riesgo cardiovascular en nuestra población infantil. Material y métodos: En este estudio participan 372 niños de ambos sexos y diferente estadio puberal con un índice de masa corporal (IMC) normal. Se determinan los valores de glucemia, insulina y péptido C (mediante quimioluminiscencia), y se calculan los índice HOMA y QUICKI. Resultados: Todos los niños presentan niveles de glucemia normales (media [DE]): 87 (7,75) mg/dl. Los valores medios obtenidos para cada variable son: insulina 7,74 (5,35) μU/ml, péptido C: 1,76 (0,79) ng/ml, índice HOMA: 1,72 (1,27), e índice QUICKI 0,72 (0,29). De forma global se objetiva un aumento progresivo de los valores de glucosa, insulina, péptido C y el índice HOMA en relación con la edad, existiendo diferencias estadísticamente significativas entre estadios prepuberales y puberales para ambos sexos, siguiendo el índice QUICKI un patrón inverso. Así mismo existen diferencias significativas entre sexos para todas las variables e índices estudiados. Los valores obtenidos para el percentil P90 para cada variable e índice de forma global son: insulina 15,05 μU/ml, péptido C: 2,85 ng/ml, índice HOMA 3,43 e índice QUICKI: 1,10. Conclusiones: Los valores de glucemia, insulina, péptido C y el índice HOMA aumentan con la edad y el estadio puberal de forma significativa. El índice QUICKI por el contrario disminuye. Establecemos el percentil P90 de estas variables que nos servirá como punto de referencia para valorar el riesgo cardiovascular en nuestra población

RESUMO

Es ampliamente conocido que la manifestación clínica más común de la infección por Salmonella enteritidis es la diarrea enteroinvasiva. Sin embargo, deberíamos tener presentes otras formas de presentación gastrointestinal menos frecuentes, en las que el dolor abdominal es selectivo y no siempre la diarrea es el síntoma principal. Éste es el caso de la ileítis terminal de causa infecciosa. La ileítis infecciosa es la infección del íleon terminal y ciego causada fundamentalmente por S. enteritidis, Yersinia enterocolítica y Campylobacter jejuni. Clínicamente, se presenta como dolor selectivo en el cuadrante inferior derecho, habitualmente con diarrea escasa o ausente, síntomas que pueden simular una apendicitis aguda. La ecografía abdominal es una técnica inocua y que suele ser válida para la discriminación entre ambas entidades a fin de evitar cirugías innecesarias. Presentamos un caso de ileítis infecciosa por S. enteritidis, destacando los hallazgos ecográficos sobre los que se estableció dicho diagnóstico


It is widely knownt hat the commonest clinical manifestation of infection by Salmonella enteritidis is diarrhea produced by this enteroinvasive pathogen. Nevertheless, we should not forget other less frequent forms of gastrointestinal presentation, such as terminal ileitis due to infection, in which abdominal pain rather than diarrhea can be the major symptom. One of these is bacterial ileocecitis. S. enteritidis, Yersinia enterocolitica and Campylobacter jejuni may specifically infect the ileocecal area. In these patients, right lower abdominal pain is the predominant symptom and diarrhea is frequently absent or only mild, symptoms that can mimic appendicitis. Ultrasound is a non invasive technique that usually helps to distinguish between these two entities and, thus, to prevent an unnecessary laparotomy. We report the case of a child with bacterial ileitis caused by S. enteritidis, with special attention to the ultrasound findings that led to the definitive diagnosis

RESUMO

Niña de 10 años con cuadro de mialgias en región gemelar que le dificulta la de ambulación v aparición de un exantema no pruriginoso, con algunos elementos nodulares en región tibial pre y posterior, y lesiones micropapulares en nalgas y muslos, sin afectación palmoplantar, acompañado de mal estado general, astenia y abdominalgia pasajera. A febril. Presentaba una exploración física normal, salvo lo referido, e intensa hiperemia de pilares amigdalinos anteriores. Entre las pruebas complementarias destaca el aislamiento de Streptococcus pyogenes en el frotis faríngeo y ASLO elevado (800 UI), con una biopsia cutánea compatible con panarteritis nudosa. Durante su ingreso recibió tratamiento con penicilina por vía oral durante 10 días negativizándose el frotis faríngeo. Presentó dolor intenso espontáneo y a la palpación en región gemelar que cedió de forma gradual. Las lesiones cutáneas fueron desapareciendo progresivamente dejando áreas residuales de hiperpigmentación. La infección estreptocócica se puede asociar a panarteritis cutánea, que puede evolucionar a panarteritis sistémica, por lo que se debe vigilar estrechamente a estos niños (AU)
