OBJECTIVE We sought to examine the relationship between the degree of prosthesis-patient mismatch and long-term survival after mechanical aortic valve replacement. METHODS Prospectively collected long-term follow-up data from 469 consecutive patients who underwent aortic valve replacement between 1995 and 1998 were reviewed. The indexed effective orifice(More)
Autologous bone marrow mononuclear cell (BM-MNC) therapy for patients with ST-segment elevation myocardial infarction (STEMI) has produced inconsistent results, possibly due to BM-MNC product heterogeneity. Patient-specific cardiovascular risk factors (CRFs) may contribute to variations in BM-MNC composition. We sought to identify associations between(More)
Childhood lead poisoning is a man-made disease whose magnitude has not yet been measured in Chile. In the U.S.A. it has been estimated that 4 percent of children have elevated blood lead levels and that among poor black children, this rate is as high as 18 percent. The main sources of symptomatic lead poisoning are lead-based paint used in interior and(More)
e11518 Background: Cystosarcoma phyllodes (CP) represents less than 1% of all breast neoplasms and can mimic fibroadenoma on core needle biopsy (CNB). When CNB specimens suggest CP, excision is recommended. However, the treatment of fibroepithelial lesions with cellular stroma on CNB is controversial as a large percentage may prove to be fibroadenoma. We(More)
A right-to-left shunt in the presence of normal pulmonary artery pressure is an unusual cause of hypoxemia in an adult who has a patent foramen ovale. We report a rare case of such a shunt-the result of a right atrial thrombus that formed in a hypercoagulable patient after placement of an indwelling central venous catheter for chemotherapy. In order to(More)
Given the importance of injury's associated mortality in children, the total number of deaths caused by injuries in subjects under 20 years of age along years 1982 through 1987 in Chile, were studied. The Annals of Mortality and Causes of Death of the Chilean National Institute of Statistics were reviewed for that period. The average annual injury's death(More)
