[Utility of diagnostic scales for hereditary non-polyposis colon cancer in the Mexican population]. / Utilidad de las escalas diagnósticas para cáncer de colon no polipósico hereditario en la población mexicana.

INTRODUCTION: Hereditary non-polyposis colorectal cancer (HNPCC) represents 2 - 7% of all cancers. Diagnosis is made by means of the Amstedam criteria, or the modified Amsterdam and Bethesda. OBJECTIVE: Aim was to evaluate the clinical application of the diagnostic scales for HNPCC in our population and to determine the clinical characteristics that these patients reveal at the time of diagnosis. METHOD: A retrospective, cross-sectional study in which patients with colon cancer and less than 50 years of age were evaluated in a period of 3 years. The demographic data, patients and relatives history and the characteristics of the tumor were obtained at the time of diagnosis. We applied the Amsterdam criteria, modified Amsterdam and Bethesda to all the patients. RESULTS: 56 of 210 patients were of 50 younger with an average age of 38.3 years. Among the patients 14.3% had familiar cancer history. In 53.6% the tumor was located in right colon, regardless histology they had mucin component and poor cellular differentiation. Only two patients fulfilled criteria of modified Amsterdam and Amsterdam, and no patient fulfilled the Bethesda criteria. CONCLUSIONS: Frequency of CCNPH in our population was 1% by the Amsterdam criteria and modified Amsterdam and 0% by the Bethesda criteria.

Drenaje percutáneo de colecciones abdominales guiadas por ultrasonido: Experiencia personal en 244 enfermos / Percutaneous drainage of abdominal abscesses: personal experience in 224 patients

Se presenta la experiencia obtenida en cinco años en el Servicio de Radiología del Hospital General "Dr. Manuel Gea González" en relación al manejo invasivo de los abscesos abdominales por drenaje percutáneo guiado por ultrasonido. Se trataron 244 pacientes con diferentes colecciones intrabdominales, a quienes se realizó drenaje por esta vía. Se drenaron 197 abscesos hepáticos amibianos, dos abscesos piógenos, dos abscesos micóticos, 10 abscesos residuales postquirúrgicos, tres abscesos perirrenales, 14 quistes renales, ocho quistes hepáticos, dos hematomas perirrenales espontáneos, dos pseudoquistes de páncreas infectados y cuatro hematomas de lecho vesicular. Se obtuvo éxito en el 97.95 por ciento de los enfermos; las complicaciones fueron mínimas
