[Independent multiple primary tumors and second primary neoplasms. Relationship between smoking]. / Tumores primarios múltiples independientes y segundas neoplasias primarias. Relación con el hábito de fumar.

Multiple primary tumors and second primary neoplasms have been increasing in incidence in recent decades and are reviewed in this paper. The reasons attributed to this significant increase are fundamentalment the best diagnosis of multiple concurrent cases and increased overall survival of patients diagnosed with cancer, allowing surface new primary tumors in other organs during or after standard monitoring. At the same time are invoked as possible causes of the widespread use of radio and chemotherapy for the first tumor. The genitourinary system is frequently involved in cases of multiple neoplasms; urological organs are one of the few settlement sites of primary tumors in almost a quarter of cases. This suggests a susceptibility/genitourinary system increased target for neoplastic disease. For this same reason, the urologist has a fundamental role in managing these patients and especially to follow up. We believe that the concept of clinical monitoring of this subset of patients should be revised, and should entail a screening of the most common second primary neoplasms since the risk of developing a subsequent independent cancer after presenting a urothelial tumor is considerably increased.

Tumores primarios múltiples independientes y segundas neoplasias primarias. Relación con el hábito de fumar / Independent multiple primary tumors and second primary neoplasms. Relationship between smoking

Los tumores primarios múltiples, así como las segundas neoplasias primarias, han experimentado un aumento de la incidencia en estas últimas décadas y son objeto de revisión en este trabajo. Los motivos que se atribuyen a este aumento significativo son fundamentalmente el mejor diagnóstico de los casos múltiples concomitantes y la mayor supervivencia en general de los pacientes diagnosticados de cáncer, lo que permite que afloren nuevos tumores primarios en otros órganos durante o después del seguimiento estándar. Al mismo tiempo, se invocan como posibles causas el extenso uso de radioterapia y quimioterapia para el primer tumor. El sistema genitourinario está muy frecuentemente implicado en los casos de neoplasias múltiples; los órganos urológicos son uno de los sitios de asentamiento de algunos de los tumores primarios en casi una cuarta parte de los casos. Esto sugiere una susceptibilidad/diana incrementada del sistema genitourinario para la enfermedad neoplásica. Y, por esta misma razón, el urólogo tiene una responsabilidad esencial en el manejo de estos pacientes y de manera especial durante el seguimiento. Creemos que el concepto de seguimiento clínico de este subgrupo de pacientes debe ser revisado y debe comportar un cribaje de las más frecuentes segundas neoplasias primarias, ya que el riesgo de desarrollar un cáncer independiente subsiguiente después de presentar un tumor urotelial está considerablemente incrementado (AU)

[Modification of nephritic colic and 24-hour calcium excretion in urine in primary hyperthyroidism after parathyroidectomy]. / Modificación de los cólicos nefríticos y de la excreción de calcio en orina de 24 horas en el hiperparatiroidismo primario tras la paratiroidectomía.

We documented the frequency of nephritic colic in patients with primary hyperparathyroidism, and determined its modification after the parathyroidectomy; we also studied laboratory parameters such as calcium, phosphorus and parathyroid hormone in serum, and the excretion of Cao 24h, previous and later to the intervention. At sight of the results it is possible to be concluded that the parathyroidectomy is useful in the treatment of the kidney stone disease produced by the primary hyperparathyroidism.

Se documentó la frecuencia de cólicos nefríticos en pacientes con hiperparatiroidismo primario, y se determinó su modificación tras la paratiroidectomía; así mismo se estudiaron parámetros de laboratorio tales como calcio, fósforo y parathormona en suero, y excreción de calcio en orina de 24h previos y posteriores a la intervención. A la vista de los resultados se puede concluir que la paratiroidectomía es útil en el tratamiento de la enfermedad calculosa renal producida por el hiperparatiroidismo primario (AU)
