Nickel release after implantation of the Amplatzer occluder.

2003

Background Transcatheter closure of atrial septal defects is a new and less traumatic technique than open heart surgery. In recent years, patients with a patent foramen ovale sustaining potential paradoxical embolism have also become candidates for interventional closure devices. One of the more popular occluding devices is the Amplatzer septal occluder, which, like many other occluders, is made of nitinol. Nitinol-based alloys are widely used in medical products, for example, in orthopedics and orthodontics. However, the clinical use of nitinol, which contains 55% nickel, is still controversial because of concerns about its biocompatibility. Therefore, we examined the systemic nickel relea…

Panintestinal capsule endoscopy in patients with celiac disease

2021

INTRODUCTION Capsule endoscopy has proven its utility in diagnosing villous atrophy and lymphoma in patients with celiac disease. Recently, a novel capsule endoscopy system was introduced which enables the examination of the small and large bowel. So far, it has not been evaluated in patients with celiac disease. OBJECTIVE The primary objective of this study was to evaluate the novel panintestinal capsule endoscopy system in patients with celiac disease. METHODS Eleven patients with histologically proven celiac disease (Marsh 0-IV), who underwent a panintestinal capsule endoscopy between March 2018 and April 2019 at our institution, were included in this retrospective single-center study. A…

Screening for celiac disease in patients with chronic liver disease

2003

Dear Sir:We read with interest the paper of Kaukinen et al. reporting anelevated frequency of celiac disease (CD) (4.3%) in patients with previousliver transplantation due to severe hepatic dysfunction.1However, wewould like to report our experience of the serologic assays for CDdiagnosis in patients with chronic liver disease and comment on thescreening methods for CD used in that study. Between January andOctober 2001, we studied 96 consecutive subjects (65 male, 31 female,age range 18–87 years, median 42) with chronic hypertransaminasemiawho were attending for thefirst time the outpatients clinic for liverdisease at the Internal Medicine Division of the University Hospital ofPalermo.

Effect of the Alterations in Contractility and Morphology Produced by Atrial Fibrillation on the Thrombosis Potential of the Left Atrial Appendage

2021

Atrial fibrillation (AF) is a common arrhythmia mainly affecting the elderly population, which can lead to serious complications such as stroke, ischaemic attack and vascular dementia. These problems are caused by thrombi which mostly originate in the left atrial appendage (LAA), a small muscular sac protruding from left atrium. The abnormal heart rhythm associated with AF results in alterations in the heart muscle contractions and in some reshaping of the cardiac chambers. This study aims to verify if and how these physiological changes can establish hemodynamic conditions in the LAA promoting thrombus formation, by means of computational fluid dynamic (CFD) analyses. In particular, sinus …

Treatment of pulmonary hypertension in patients undergoing cardiac surgery with cardiopulmonary bypass: a randomized, prospective, double-blind study

2006

Pulmonary hypertension can already be present in patients undergoing cardiac surgery or can be exacerbated by cardiopulmonary bypass. Postoperative treatment is still a challenge for physicians. The aim of this study was to evaluate the effects of inhaled prostacyclin (iPGI2) and nitric oxide (iNO) compared with those of intravenous vasodilators.This prospective, randomized, double-blind study included 58 patients affected by severe mitral valve stenosis and pulmonary hypertension with high pulmonary vascular resistance (250 dynes x s x cm(-5)) and a mean pulmonary artery pressure25 mmHg. All patients were monitored by central venous, radial arterial and Swan-Ganz catheters. Data were recor…

Prospective external validation of a predictive score for postoperative pulmonary complications.

2015

Abstract Background: No externally validated risk score for postoperative pulmonary complications (PPCs) is currently available. The authors tested the generalizability of the Assess Respiratory Risk in Surgical Patients in Catalonia risk score for PPCs in a large European cohort (Prospective Evaluation of a RIsk Score for postoperative pulmonary COmPlications in Europe). Methods: Sixty-three centers recruited 5,859 surgical patients receiving general, neuraxial, or plexus block anesthesia. The Assess Respiratory Risk in Surgical Patients in Catalonia factors (age, preoperative arterial oxygen saturation in air, acute respiratory infection during the previous month, preoperative anemia, upp…
