Background Breast cancer is the most common malignant tumor in women in the world. In 2005, it was incorporated to the Explicit Guaranties Health System (GES) in Chile. Aim To describe the demographic and clinical characteristics of breast cancer patients and to determine the effect of incorporating these women to GES. Material and Methods Medical records of 5,119 women with breast cancer aged 59 ± 14 years, attended at six public hospitals between 2000 and 2010 were reviewed. Median follow up was 87 months (range 1-182). Mortality was assessed using death certificates obtained at the National Identification Registry. Results Sixty six percent of women were in stage I-II, 29% in stage III and 5% in stage IV. Surgery was performed in 4023/5119 cases (79%), adyuvant radiotherapy in 3627/4517 cases (80%), chemotherapy in 3,204/3,424 cases (94%) and hormone therapy in 1,695/2,375 cases (71%). Between 2000 and 2010, there was a significant increase in the proportion of cases in stage I, from 8% to 25%, (p < 0.01). Overall survival (OS) increased 1% per year, since the beginning of GES system (p = 0.024). Five year OS was 75.1%. The figures for Stage I, II, III and IV were 93, 84, 62 and 27% respectively (p < 0.01). Patients without lymph node involvement and who were not triple negative, had a significantly better OS. Conclusions There was a significant increase in stage I cases, and a 1% per year OS improvement after GES system started, compared with the previous period.

Hiperplasia angiolinfoide con eosinofilia: a propósito de dos casos / Angiolymphoid hyperplasia with eosinophilia: a propos of two cases

La Hiperplasia Angiolinfoide con Eosinofilia (HALE) es una proliferación vascular benigna, poco frecuente, que se caracteriza por nódulos localizados preferentemente en el cuero cabelludo, región periauricular y cuello, en adultos jóvenes. La histopatología muestra proliferación de vasos sanguíneos con endotelio prominente, acompañada de un infiltrado inflamatorio que incluye eosinófilos y linficitos. El tratamientos de elección es la resección quirúrgica; sin embargo, las recurrencias son frecuentes. Se presentan dos casos clínicos, se revisa la literatura y se discute la relación entre HALE y enfermedad de Kimura.

Diverticulosis yeyunal una causa infrecuente de hemorragia digestiva: caso clínico / Jejunal diverticulosis as cause of gastrointestinal hemorrhages: case report

Jejunal diverticulosis is a very uncommon acquired disease. Clinical manifestations include acute life threatening complication such as perforation, obstruction and bleeding. Jejunal diverticulosis is an extremely rare site of origin of gastrointestinal bleeding, with fewer than seventy cases reported in the literature. We report a 77-year -old patient with a recurrent severe gastrointestinal bleeding manifested by melena and hematochaezia. During the hospitalization the tagged red blood cell scanning was positive for bleeding in the jejunum. At laparotomy, several large-mouthed diverticula at the proximal jejunum were identified. Approximately 30 centimeters of the involved segment was resected with primary end-to-end anastomosis. Postoperative 7 month evolution has been favorable, without any evidence of rebleeding. This report reviews the literature concerning this disease, discusses some diagnostic methods of studying small bowel bleeding and highlights the need to consider this diagnosis in old patients with a gastrointestinal hemorrhage of unknown origin
