ABSTRACT
Introducción La micosis fungoide foliculotropa es una variante de mal pronóstico y presentación clínica variada. Se ha planteado que la estadificación TNMB usada para esta neoplasia no es útil. En una propuesta reciente basada en aspectos clínicos e histológicos, se clasifica en enfermedad temprana y avanzada, encontrando diferencias pronósticas entre las 2categorías. El objetivo de este estudio fue comparar la supervivencia de estos 2 grupos en nuestra población. Materiales y métodos Se realizó un estudio observacional retrospectivo de serie de casos donde se evaluó la evolución clínica de los pacientes con micosis fungoide foliculotropa tratados en el Instituto Nacional de Cancerología entre el 2008 y el 2020, realizando un análisis comparativo de supervivencia entre aquellos que tienen enfermedad temprana y enfermedad avanzada. Resultados Se incluyó a un total de 21 pacientes, 11 de los cuales presentaban enfermedad temprana y 10 enfermedad avanzada. Se identificaron 7 decesos, todos ellos en los pacientes con enfermedad avanzada. La supervivencia global de la población total a 5 años fue del 62%, mientras que para la población con enfermedad avanzada fue del 40%. No hubo diferencias en la supervivencia según la estadificación TNMB. Conclusión La estadificación TNMB no es útil para los pacientes con una micosis fungoide foliculotropa. Por el contrario, la nueva clasificación clínico-patológica parece brindar información pronóstica fiable y permite tomar medidas terapéuticas acordes (AU)
Introduction Folliculotropic mycosis fungoides is a variant that has poor prognosis and a variable clinical presentation. Concerns have been expressed that the current TNMB staging of this tumor may not be useful. A recently developed classification system based on clinical and histologic variables classifies this tumor as early or advanced, a distinction found to correlate with prognosis. The aim of this study was to compare survival in FMF in Colombia between patients with early versus advanced tumors. Material and methods Retrospective, observational study of clinical course and outcomes in patients with FMF treated at the National Cancer Institute of Colombia between 2008 and 2020. Survival was compared between early and advanced disease. Results Twenty-one patients (11 with early FMF and 10 with advanced FMF) were studied. Seven patients, all with advanced disease, died. Survival at 5 years was 62% overall and 40% for patients with advanced FMF. No differences were observed when survival was analyzed according to TNMB stage. Conclusions TNMB staging is not useful in FMF. The new classification system based on clinicopathologic features appears to provide reliable information for assessing prognosis and guiding treatment decisions (AU)

OBJECTIVE: To evaluate the efficacy of densitometric analysis of cranial CT imaging in the measurement of areas with low cerebral blood flow and lack of hemodynamic reserve in patients undergoing carotid endarterectomy. PATIENTS AND METHODS: 40 consecutive patients undergoing carotid endarterectomy have been included in the study. All of them had preoperative cranial CT, pre and postoperative basal and acetazolamide SPECT. Cranial CT imaging after digitalization and computer processing were obtained with 4 densitometric patterns: 1). normal cerebral blood perfusion; 2). ischemic or low brain blood perfusion (patron I); 3). parenchyma without cerebral hemodynamic reserve (patron nR), and 4). brain infarction. RESULTS: 32 out of 40 (80 %) patients had abnormal densitometric patterns: 19 nR patterns (47.5 %), 11 I pattern (27.5 %) and 2 established brain infarction. The correlation between densitometric cranial TC imaging and SPECT was 92% when analyzing areas with hypoperfusion (S: 96.5 %; E: 82 %). Cranial CT detected 12/13 of patients who lacked cerebral hemodynamic reserve in the SPECT analysis (S: 74 %; E: 92 %; Vpp: 95 %). CONCLUSIONS: There is a good correlation between analysis of densitometric cranial TC imaging and SPECT in determining low cerebral blood flow areas and lack of cerebral hemodynamic reserve. This method could help to improve carotid surgery indications in patients with carotid stenosis.

A case of spontaneous acute infrarenal aortic dissection, with extension to the right common iliac artery and proximally to just below the origin of the renal arteries is presented. This dissection did not involve the visceral vessels nor the iliac system. The diagnosis was made with ultrasonography and computed tomography, without the need for angiography, and confirmed during surgical intervention, in which, prosthetic replacement of the affected segment was carried out.
