ABSTRACT

We report a 20-year-old male athlete who while running, presented a sudden death due to ventricular fibrillation. He was successfully rescued by cardiopulmonary resuscitation maneuvers and an automatic external defibrillator. Without evidence of structural heart disease, Brugada syndrome was diagnosed as the cause, after which a subcutaneous implantable cardioverter defibrillator was indicated. We discuss the subject of sudden cardiac death in athletes and its unusual relationship with exercise in this channelopathy.

ABSTRACT

El antígeno carcinoembrionario (ACE) es una glicoproteína que se encuentra en el endodermo primitivo y está ausente en la mucosa normal del adulto. Es usado como marcador tumoral en cáncer de colon, pero su utilidad es discutida. OBJETIVO: Evaluar la asociación del ACE preoperatorio con variables anatomopatológicas y de etapificación según TNM. MATERIALES Y MÉTODOS: Se revisaron 41 fichas clínicas de pacientes atendidos por cáncer de colon durante el año 2007 en el Hospital Clínico San Borja-Arriarán. La concentración sérica del ACE fue determinada mediante la técnica de inmuno-enzimoanálisis de micropartículas. Se utilizó el programa STATA9 para el análisis estadístico y se consideró significativo un p < 0.05. RESULTADOS: No existen diferencias entre las distintas localizaciones del tumor, histología, grado de diferenciación celular e invasión perineural, vascular y linfática del tumor.Se encontraron diferencias significativas en la etapificación según TNM. Tumores T1 poseen niveles menores que tumores T4; compromiso ganglionar N1 tiene niveles mayores que N2; el estadio1 tiene niveles menores que el estadio 3 y 4. CONCLUSIONES: El nivel plasmático de ACE preoperatorio tiene mayor correspondencia con variables de etapificación y no tiene asociación con variables anatomopatológicas, demostrando su utilidad en el proceso de etapificación clínica prequirúrgica. Sin embargo, se requieren estudios dirigidos para comprender la ventaja de este marcador como instrumento de etapificación.


The carcinoembryonic antigen (CEA) is a glycoprotein found in the primitive endoderm and is absent in normal adult mucosa. It is used as a tumor marker in colon cancer, but its usefulness is discussed. OBJECTIVE: To evaluate the association of presurgical ACE levels and pathological variables according to TNM staging. MATERIALS AND METHODS: 41 medical records were reviewed of patients seen per colon cancer in 2007 at the Hospital Clínico San Borja-Arriarán. STATA9 was used for statistical analysis and we considered significant p <0.05. RESULTS: There were not differences between tumor sites, histology, grade of cell differentiation and perineural, vascular and lymphatic invasion of the tumor. We found significant differences in the presurgical CEA levels according to TNM staging. T1 tumors have levels lower than T4 tumors; N1 lymph node involvement has greater levels than N2; stage 1 has smaller levels than the stage 3 and 4. CONCLUTIONS: The level of presurgical plasma CEA has higher correlation with staging variables than pathological variables, demonstrating its usefulness in the clinical staging process. However, studies are required aimed to understand the advantage of this marker as a means of staging.
