RESUMO

The first renal biopsies, made as much in adults as in children, were surgical. They were made to patients who were under renal decapsulation with the intention to reduce the kidney pressure, especially in cases of nephrotic syndrome. In 1944, Nils Alwall initiated the accomplishment of percutaneous kidney biopsies by means of a needle and aspiration at the University of Lund (Sweden), although his experience was published in 1952. The first article that had by subject the practice of a percutaneous renal biopsy was written in 1950 by a Cuban doctor, Antonino Pérez Ara, and published in a local journal with little diffusion. The first work that appeared in a Spanish journal (1953) about the practice of the percutaneus renal biopsies was not signed by any Spanish group but by members of the Hospital "Calixto García" of the University of The Havana, Cuba. The first article published in Spain regarding to this subject, saw the light in 1958, now 50 years ago, in the Revista Clínica Española. The two first signers were Alfonso de la Peña Pineda and Vicente Gilsanz García, professors of the Medicine Faculty of Madrid. Later, the practice of the percutaneous renal biopsy became general in other Spanish hospitals.

RESUMO

La monitorización ambulatoria de la presión arterial (MAPA) permite evaluar no sólo las elevaciones casuales de la presión arterial (PA) durante el día, sino también las alteraciones en el patrón circadiano de la PA a lo largo de las 24horas. El objetivo del presente estudio es evaluar los patrones de PA a lo largo de 24 horas en una población de niños obesos remitidos a la consulta de nuestro hospital, valorando su relación con el grado de obesidad e insulin resistencia. Métodos: Se estudiaron 119 niños obesos (edades 7-15años) a los que se les determinó la PA clínica y ambulatoria, así como un estudio bioquímico para la determinación de glucosa, insulina y cálculo de HOMA, y determinación de microalbuminuria en la primera orina de la mañana. El grado de sobrepeso se estableció según la puntuación z del índice de masa corporal (IMC) acorde a su edad y sexo. Resultados: El 47% de los pacientes presentaban unas cifras elevadas de PA sistólica clínica en la primera y única medida de PA en el tiempo, sin confirmación en visitas sucesivas. La prevalencia global de hipertensión (HTA) medida por MAPA era del 36%. El 14% eran hipertensos sistólicos diurnos, y el33% (n = 39) hipertensos sistólicos nocturnos. De estos últimos, veinticinco de ellos (64%) sólo eran hipertensos sistólicos durante la noche, y el resto (n = 14), también lo eran durante el día. Sólo cuatro pacientes eran hipertensos sistólicos diurnos de manera aislada. Ningún paciente presentó una hipertensión diastólica aislada diurna o nocturna. En el 47% del total de pacientes (n=56) no se producía el descenso nocturno esperado de la PA sistólica. Esta pérdida del patrón circadiano de la PA dependía tanto del grado de obesidad (p <0 001 como de la insulinresistencia p <0 001 expresado según valores de homa conclusiones: en nuestra muestra niños obesos las cifras elevadas pa sistólica nocturna y la atenuación del descenso nocturno fisiológico constituyen forma más frecuente hipertensión este fenómeno se asocia al grado obesidad e insulinresistencia (AU)


Ambulatory blood pressure monitoring (ABPM) allows evaluation not only of casual daytime elevations of blood pressure (BP)but also alterations in the 24-hour circadian patterns of BP. The aim of the present study was to assess 24-hour BP patterns in a population of obese children who were referred to our out patient clinic, in relation to the degree of obesity and insulin resistance. Methods: Office and ambulatory BP measurements, and fasting serum glucose, insulin and HOMA determinations were obtained in 119 obese children (7-15 years old). Urinary albumin excretion was measured in the first morning urine. The extend of obesity was quantified using body mass index z score adjusted by age and gender. Results: The prevalence of office hypertension in only one set of blood pressure measurements was 47%. This value was not confirmed on further separate occasions. The prevalence of global ambulatory hypertension was 36%. Diurnal systolic hypertension was found in 14%, while 39 patients (33%) had nocturnal systolic hypertension. Twenty five of them (64%) were only hypertensive at nightime and the rest (n = 14), were also hypertensive during the day. Only 4 patients were exclusively systolic hypertensive at daytime (table III). None of the patients were exclusively diastolic at day or nightime. Of the total 119 subjects,47% were non systolic dippers.

RESUMO

UNLABELLED: Ambulatory blood pressure monitoring (ABPM) allows evaluation not only of casual daytime elevations of blood pressure (BP) but also alterations in the 24-hour circadian patterns of BP. The aim of the present study was to assess 24-hour BP patterns in a population of obese children who were referred to our outpatient clinic, in relation to the degree of obesity, body fat distribution and insulin resistance, and considering other cardiovascular risk factors. METHODS: Office and ambulatory BP measurements, and fasting serum glucose, insulin and HOMA determinations were obtained in 119 obese children (7-15 years old). Urinary albumin excretion was measured in the first morning urine. The extend of obesity was quantified using body mass index z score adjusted by age and gender. RESULTS: The prevalence of office hypertension in only one set of blood pressure measurements was 47%. This value was not confirmed on further separate occasions. The prevalence of global ambulatory hypertension was 36%. Diurnal systolic hypertension was found in 14%, while 39 patients (33%) had nocturnal systolic hypertension. Twenty five of them (64%) were only hypertensive at nightime and the rest (n = 14), were also hypertensive during the day. Only 4 patients were exclusively systolic hypertensive at daytime (table III). None of the patients were exclusively diastolic at day or nighttime. Of the total 119 subjects 47% non systolic dippers. This abnormal BP pattern was associated with the degree of obesity (p < 0.001) and insulinresistance (HOMA values; p < 0.001). The anthropometric and metabolic characteristics of the population studied are shown in table I and II respectively. The correlations coefficients and regression analysis between anthropometric and metabolic parameters are shown in table IV and V. CONCLUSION: Reduced nocturnal systolic blood pressure dip and nightime systolic hypertension were the most frequent forms of hypertension in our cohort of severe obese children. These alterations in the 24-hour circadian patterns of BP were related to the degree of obesity and insulin resistance.

RESUMO

El tratamiento nutricional de los errores innatos del metabolismo (EIM) constituye en la actualidad el pilar más importante en el manejo global de estas enfermedades. Nuestra intervención dietética no sólo debe intentar asegurar un adecuado crecimiento y desarrollo del niño sino que, al mismo tiempo, tenemos que programar un enfoque nutricional específico según el defecto metabólico del que se trate. En este artículo (segundo de cinco partes) y el siguiente abordamos los aspectos diatéticos y nutricionales de algunos de los trastornos más frecuentes que afectan el metabolismo de los aminoácidos (AU)
