Sarcoidosis is a multisystem disorder that is characterized by noncaseous epithelioid cell granulomas, which may affect almost any organ. Thoracic involvement is common and accounts for most of the morbidity and mortality associated with the disease. Thoracic radiologic abnormalities are seen at some stage in approximately 90% of patients with sarcoidosis,(More)
OBJECTIVE Giant cell arteritis (GCA) may involve the aorta. Retrospective studies have demonstrated a higher prevalence of aortic aneurysm among patients with GCA compared with the general population. We investigated the prevalence of aortic aneurysm in a cohort of patients with biopsy-proven GCA using a defined protocol and assessed whether persisting(More)
BACKGROUND Necroscopic and surgical studies have suggested that giant cell arteritis (GCA) may target the aorta and its main branches. Imaging techniques are able to detect large vessel vasculitis (LVV) non-invasively in patients, but the prevalence of LVV in GCA has not been clearly established. OBJECTIVE To assess prospectively the prevalence,(More)
The presence of biliary leaks after liver resections is not an unusual problem, especially after extended hepatectomies. The usual treatment of choice for biliary duct injuries is to decompress the biliary system with draining catheters. Persistent biliary fistulas are nevertheless a challenging problem when endoscopic or percutaneous approaches fail to(More)
Computed tomography angiography (CTA) detects signs of large-vessel vasculitis (LVV) in about 67.5% of patients with giant-cell arteritis (GCA) at the time of diagnosis and early aortic dilatation in 15%. The outcome of CTA-findings of LVV upon glucocorticoid treatment has not been prospectively evaluated. The aim of our study was to prospectively assess(More)
Acral melanoma (AM) is associated with a poor prognosis in part because of delayed diagnosis, but probably also because of other intrinsic characteristics of location. The aim of this study was to review the specific characteristics and outcome of AM in Caucasians. This was a cross-sectional retrospective clinical-pathological study of 274 patients(More)
We assessed the usefulness of routine Doppler ultrasonography for early detection of hepatic artery thrombosis after orthotopic liver transplantation and repercussions in patient prognosis. Seventeen confirmed cases of early hepatic artery thrombosis initially diagnosed by Doppler ultrasonography (10 of them before clinical indication) were reviewed. All(More)
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease with limited response to currently available therapies. Alveolar type II (ATII) cells act as progenitor cells in the adult lung, contributing to alveolar repair during pulmonary injury. However, in IPF, ATII cells die and are replaced by fibroblasts and myofibroblasts. In(More)
OBJECTIVE To study the outcomes of broncho ± angioplastic sleeve lobectomy (SL) versus pneumonectomy (PN), and the PN:SL ratio after an aggressive policy of parenchyma-sparing surgery to improve postoperative complications rate and long-term quality of life (QoL). METHODS A prospective study was conducted in 490 patients with non-small cell lung cancer(More)
OBJECTIVE This study sought to assess the real incidence of pN2 among patients with non-small-cell lung cancer (NSCLC) (cN0) with negative mediastinal uptake of 2-deoxy-2-(18F)-fluoro-o-glucose (FDG). METHODS During 30 consecutive months (January 2007-May 2009), all patients with NSCLC scheduled for surgery in our unit had a preoperative FDG-positron(More)
