RESUMO
Se presentan dos casos de enfermedad de Berger, glomerulonefritis caracterizada por depositos mesangiales de IgA. La patogenia del cuadro no se conoce bien, sin embargo, se ha planteado que se debe a complejos inmunes. Clinicamente se caracteriza por hematurias que se presentan a raiz de infecciones del tracto respiratorio superior. Un 25% de los casos evoluciona hacia la insuficiencia renal. Actualmente no hay un tratamiento eficaz que sea capaz de prevenir o detener esta evolucion desfavorable

Two blood pressure (BP) measurements separated by 3 months were performed according to international guidelines on 2976 students (11 to 19 years) of different economic levels. Obesity was defined based upon height and weight. With the first measurements, 59th and 95th percentile value distribution curves were defined. Systolic hypertension (SH) was found in 9.5%; 10.2% were males and 8.9% females. The sample showed that 8.1% were obese (240 cases); among them the incidence of SH increased to 28.8% (69 cases) (p less than 0.01). In the entire sample, diastolic hypertension (DH) was 4.3%; males, 2.7%, and females, 5.5% (p less than 0.01). Among obese students, DH increased to 8.3% (20 cases) (p less than 0.01), and showed prevalence figures of 5.8% for obese males and 10.3% (14 cases) for obese females. After a second measurement, DH for the sample decreased to 1.8%. Salt intake and familial antecedents of high BP showed differences between hypertensive and normal populations.

Con una determinacion individual de presion arterial obtenida de 3.442 escolares chilenos urbanos entre 6 y 19 anos se construyeron curvas de distribucion por percentiles para cada edad y sexo. Las mediciones se efectuaron durante 1979 y 1980 siguiendo las recomendaciones de la American Task Force on Blood Pressure Control in Children de EE.UU.Solo en 34.5% de los estudiantes tenian determinaciones previas de presion arterial.Los valores nacionales se comparan con los de EE.UU. y se destacan las diferencias. Al mismo tiempo se discute la confiabilidad de la cifra 140/90 mm Hg. como valor limite de la normotension. Este primer intento nacional para establecer los limites normales de la presion arterial se ofrece para su prueba en la practica pediatrica cotidiana y para facilitar la interpretacion de los valores obtenidos
