Latex agglutination (LA), passive hemagglutination (PHA), immunoelectrophoresis (IEP) and specific IgE, IgM, IgG enzyme-linked immunosorbent assay (ELISA) tests for diagnosis and postoperative follow-up of 79 patients with surgically confirmed pulmonary hydatidosis were evaluated. Specific IgG ELISA was the most sensitive test (83.5%) and the least(More)
BACKGROUND This study examines the experience of the Spanish Multi-centric Study of Neuroendocrine Tumours of the Lung with patients treated surgically for typical and atypical carcinoid tumours. METHODS From 1980 to 2002, 661 patients were treated surgically for 569 typical carcinoid tumours and 92 atypical carcinoid tumours. Three hundred and four cases(More)
Four different recombinant antigens derived from Echinococcus granulosus, designated B1t, B2t, E14t, and C317, were tested with enzyme-linked immunosorbent assays (ELISAs) for the detection of specific immunoglobulin G (IgG) in patients with unilocular hydatid disease (UHD). The results were compared to those obtained with hydatid fluid and were subjected(More)
BACKGROUND We prospectively analyzed the postoperative morbidity, mortality rate, and risk factors in 605 patients who underwent thoracotomy for bronchogenic carcinoma. METHODS Patients were categorized by postsurgical tumor stage: I, 287 patients (47.4%); II, 49 patients (8.1%); IIIA, 154 patients (25.5%); IIIB, 80 patients (13.2%); IV, 16 patients(More)
This study was designed to analyze the hemodynamic and cerebral repercussions arising from the surgical interruption of the superior vena cava. The experiments were carried out in 12 mongrel dogs under two different conditions: with shunt (group A, n = 6) and without the installation of a shunt (group B, n = 6). The period of occlusion was 35 minutes. The(More)
BACKGROUND This study examines the experience of the Spanish Multicenter Study of Neuroendocrine Tumors of the Lung through the clinical data and behavior of patients treated for this pathologic process. METHODS From 1980 to 1997, 361 cases of neuroendocrine carcinomas (NEC) were treated surgically. Patients were enrolled in a protocol using the(More)
A standardized test for the serodiagnosis of human cystic echinococcosis (CE) is still needed, because of the low specificity and sensitivity of the currently available commercial tools and the lack of proper evaluation of the existing recombinant antigens. In a previous work, we defined the new ELISA-B2t diagnostic tool for the detection of specific IgGs(More)
Hydatidosis in humans is a parasitic disease produced by cystic growth of the larvae of the tapeworm Echinococcus granulosus, affecting mainly the liver and lung. Larvae are rarely present in the mediastinum, although approximately 100 cases have been described in the literature. We report eight cases of hydatid cysts of the mediastinum (HCM) treated(More)
BACKGROUND The purpose of this study is to report our 15-year experience treating chronic empyemas after pulmonary resection and tuberculosis. METHODS Open-window thoracostomy and thoracomyoplasty were used to treat 40 patients with chronic pleural empyema characterized by residual empyematic cavity, bronchopleural fistula, and persistent pleural(More)
A prospective observational study of central venous catheters (CVC) was carried out in order to determine if a CVC inserted near an open burn wound increases catheter infection risk in burned patients. The study was carried out during a 12-month period (1998-1999) at the Benaim Foundation's Burn Unit in Buenos Aires (C.E.P.A.Q.). Eighty-three CVCs were(More)
