Extracorporeal photopheresis (ECP) may represent an alternative to immunosuppression, as a means of reducing rejection after thoracic organ transplantation. The mechanism by which ECP exerts its protective effects has, until now, remained elusive. We analyzed peripheral blood mononuclear cells of four children with chronic heart and lung transplant(More)
OBJECTIVES The goal of this study was to evaluate percutaneous interventional and minimally invasive surgical closure of secundum atrial septal defect (ASD) in children. BACKGROUND Concern has surrounded abandoning conventional midline sternotomy in favor of the less invasive approaches pursuing a better cosmetic result and a more rational resource(More)
The literature has few data regarding the use of polyclonal anti-thymocyte globulin in pediatric cardiac transplantation. We describe our single-center, retrospective study of the use of Thymoglobuline in a pediatric population. We included in the study 31 consecutive heart transplant recipients (mean age, 7.8 years; median age, 9 years; range, 4 months-17(More)
On the Complexity of Probabilistic Abstract Argumentation 1 / 24 Introduction Background Complexity results Conclusions and future work Motivation Contribution Argumentation in AI A general way for representing arguments and relationships (rebuttals) between them It allows representing dialogues, making decisions, and handling inconsistency and uncertainty(More)
OBJECTIVE Evaluation of incremental risk factors for early mortality in children undergoing orthotopic heart transplantation (OHT) for congenital heart disease. METHODS Between 1988 and 2002, 43 patients (mean age 9.1+/-7.2 years) underwent 44 OHT for complex TGA (6), DORV (4), single ventricle (21), and other end-stage structural heart disease (11). Two(More)
PURPOSE To evaluate long-term outcome of intravitreal anti-vascular endothelial growth factor monotherapy in retinal angiomatous proliferation. METHODS Twenty-one treatment-naive eyes were included in this prospective, interventional case series. Treatment was three monthly injections of bevacizumab and/or ranibizumab with a modified PrONTO-style regimen.(More)
BACKGROUND Morbidity and mortality of emergency repair of type A dissecting aneurysms of the aorta are high. This is an attempt to investigate the risk determinants of early and late results. METHODS A series of preoperative and operative variables were retrospectively collected from the clinical records of 291 patients operated on between January 1,(More)
BACKGROUND The involvement of retina and its vasculature has been recently described in Alzheimer's disease (AD). However, none of the previous works have yet investigated the choroid in vivo. OBJECTIVE Spectral domain optical coherence tomography (SD-OCT) and enhanced depth imaging (EDI) technique is non-invasively used to assess choroidal thickness in(More)
Myoelectric activity of the sigmoid has been studied in 12 patients with chronic nonorganic constipation and 10 control subjects. All patients showed total gastrointestinal transit time longer than 96 h, with left-colonic or rectocolonic slowed transit. Electrical and mechanical activity was recorded by means of an intraluminal probe with bipolar suction(More)
BACKGROUND Knowledge of time course and risk factors for morbidity and mortality may allow better cardiac graft allocation, surveillance timing, and planning of immunosuppressive strategies. METHODS Six-month morbidity and mortality were retrospectively analyzed in a multiinstitutional series of 645 heart transplant recipients. RESULTS During a 3432(More)
