We have revised the clinical, radiological and pathological characteristics of Xanthogranuloma-tous pyelonephritis (XGP), together with the evolution of the disease and a literature review of the same. A retrospective study was performed at our center, obtaining a sample of 8 pathologically confirmed cases which we used to describe the clinical and diagnostic features. Of the 8 cases (1 male and 7 female), 6 of them presented complicated renal colic, one presented asthenia and weight loss and the other case was an incidental finding. The initial diagnosis was achieved with ultrasonography in 2 of the cases and with CT in all of the cases, all being confirmed by a histopathological study.

Hemos revisado las características clínicas, radiológicas y patológicas de la pielonefritis xan-togranulomatosa junto con la evolución de la enfermedad y una revisión bibliográfica de la misma. Se realiza un estudio retrospectivo en nuestro centro, obteniendo una muestra de 8 casos confirmados por anatomía patológica a través de los que describimos las características clínicas y diagnósticas. De los 8 casos (1 varón y 7 mujeres), 6 de ellos debutaron como cólico renal complicado, 1 se presentó con astenia y pérdida de peso y el otro caso fue un hallazgo incidental. El diagnóstico inicial se realizó mediante ecografía en 2 casos y TC en todos los casos, siendo confirmados todos mediante estudio histopatológico.

The pathogenicity of seven strains of Fusarium equiseti isolated from seabed soil was evaluated on different host plants showing pre and post emergence damage. Radial growth of 27 strains was measured on culture media previously adjusted to different osmotic potentials with either KCl or NaCl (-1.50 to - 144.54 bars) at 15º, 25º and 35º C. Significant differences and interactive effects were observed in the response of mycelia to osmotic potential and temperature.
