La encefalopatía hiperamonémica, una posible complicación por derivación urinaria tras cistectomía radical. Revisión de la literatura a proposito de un caso / Hyperammonaemic encephalopathy, possible complication after urinary diversion in radical cystectomy. Review of the literature with regard to a clinical case

Introducción: La cistectomía radical es una intervención con una elevada morbilidad. Las derivaciones postcistectomía pueden ocasionar complicaciones metabólicas como la encefalopatía hiperamonémica. Caso Clínico: Presentamos el caso de una paciente cistectomizada por un carcinoma vesical con posterior ureterosigmoidostomía. Tras la intervención acudió en 4 ocasiones con síntomas neurológicos y confusión. Todo el estudio analítico y pruebas de imagen fueron normales. Los niveles de amonio en sangre estaban elevados. Tras tratamiento de soporte y hemodiálisis la clínica desapareció. Posteriormente fue sometida a una nueva derivación quirúrgica (conducto ileal). Discusión: El empleo de técnicas de derivación continentes tras la cistectomía se aconseja ante la importante afectación de la calidad de vida que produce el conducto ileal. Sin embargo, estas técnicas tienen complicaciones, como la encefalopatía hiperamonémica de causa no hepática. La elevada absorción de amonio por el epitelio intestinal de la neovejiga induce una encefalopatía. Es esencial su diagnóstico temprano con el fin de iniciar un tratamiento eficaz

Introduction: Radical cystectomy is an intervention with an important morbidity. Urinary diversion is a possible cause of metabolic complications like hyperammonaemic encephalopathy. Case report: We present the case of a patient treated with a radical cystectomy and modified ureterosigmoidostomy after diagnosis of bladder cancer. After surgery the patient presented in 4 ocasions recurrent episodic confusion. Laboratory and image tests were normal. Levels of seric ammonium was increased. After supportive treatment and hemodyalisis symptoms disappeared. Later patient was reoperated and a reconstruction to ileal conduit was made. Discussion: Continent urinary diversions are advised due to important negative impact on quality of life produced by ileal conduit. However these diversions have several complications, like encephalopathy secondary to non-hepatic hyperammonaemia. Increased absortion of ammonium by intestinal tissue of the new-ladder induces encephalopathy. Early diagnosis of this complication is essencial in order to administer an effective treatment

Flegmasia cerulea dolens en paciente con carcinoma testicular / Phlegmasia cerulea dolens in patients with testicular carcinoma

Describimos un caso de flegmasia cerulea dolens secundaria a una trombosis venosa profunda por compresión de la vena cava inferior, en un varón de 31 años con un tumor germinal. Necesitó un tratamiento urgente con agentes fibrinolíticos, heparina intravenosa y quimioterapia. Con el tratamiento obtuvo una respuesta completa tumoral y una completa revascularización de la vena cava y vena femoral derecha

We describe a case of phlegmasia cerulea dolens secondary to venous thrombosis due to compression of inferior vena cava, in a 31-year-old man with a germ cell tumour. He was treated with systemic thrombolytic agents, intravenous heparin and urgent chemotherapy He presented a complete tumoral response and complete revascularization of the vena cava and right femoral vein

SEOM clinical guidelines for the treatment of advanced colorectal cancer

Colorectal cancer is the first cause of cancer diagnosis in Spain. Over half of the patients are diagnosed with or will eventually develop distant metastasis. The current manuscript aims to provide synthetic practical guidelines for the therapeutic approaches in advanced disease. Available systemic therapeutic options, and integration and sequencing of chemotherapy with surgical procedures are discussed. Extent of disease, treatment objective, tumor kras mutation status, as well as patient's functional and comorbid conditions shall be considered to properly design the most adequate therapeutic strategy (AU)

Treatment guidelines in ovarian cancer

National and international specialists have met with the aim of writing down the guidelines for the treatment of epithelial ovarian cancer (in the Spanish Castilian language). These guidelines are based on the International Consensus that was published in English in the Annals of Oncology in 2005. This condition is the leading cause of death from gynaecological cancer in western countries. Its low rate of survival, barely 30% at 5 years, is above all due to late diagnosis and inappropriate surgery, so emphasis is put on these aspects. After describing the methodology for early detection and a scheme of surgical diagnostic procedures in view of the staging of an ovarian mass, the following therapeutic strategies will be recommended: cytoreductive surgery together with platinum chemotherapy under normal conditions, and also in the case of relapse. Likewise, very recent models of treatment focused on molecular targets are presented, and a broad section on methodology of clinical assays. As for this, co-operation among groups is crucial in order to make the conclusions of these studies valid for the development of new therapies (AU)
