The "accordion effect" is a mechanical remodeling of the arterial wall produced by endoluminal introduction of stiff guidewires, leading to vessel wall shortening and development of multiple eccentric constrictions. This phenomenon is unresponsive to vasodilators and may lead to unnecessary stenting of the pseudo-lesions. It must be suspected with the(More)
Data from the national tumor registry of Costa Rica for the years 1979-1983 have been used to calculate incidence rates for the major cancer sites by age, sex, urban-rural residence, and geographic region. Recent trends in mortality rates are also presented. Results are compared with data from elsewhere in Latin America, U.S.A., Europe, and Japan. Stomach(More)
Vessel wall shortening and deformity due to "arterial telescoping" is a not infrequent reversible phenomenon that occurs during coronary angioplasty and is associated with the advancement of a stiff wire through elongated and tortuous segments, with straightening of the artery and deep guiding catheter introduction beyond the coronary ostium. We present the(More)
BACKGROUND Sepsis is the commonest complication of small bowel transplantation. These infections are presumably caused by bacterial translocation, due to splanchnic ischemia. AIM To study bacterial translocation in the immediate postoperative period after a small bowel transplantation in dogs and to relate it to splanchnic ischemia. METHODS Three groups(More)
BACKGROUND AND AIMS Diabetes mellitus is one of the major risk factors for coronary artery disease. The aim of this study was to evaluate in-hospital mortality and during follow-up of diabetic patients with acute myocardial infarction treated with primary angioplasty and to determine its predictors. MATERIALS AND METHODS Eight hundred and sixty six(More)
