Although replantation of fingertip is technically possible, advances in microsurgery have made salvage of amputated fingers a commonly performed procedure. In the present study, we aimed to evaluate the functional outcomes after retrograde (RAA) versus antegrade (AAA) palm arteriovenous anastomosis in the distal fingertip replantation. The results showed that survival rate, appearance and digit...

OBJECTIVE Reactive oxygen species may act as proinflammatory mediators in abdominal aortic aneurysm (AAA) disease. Flow loading increases antioxidative enzyme expression and limits reactive oxygen species production in vascular smooth muscle cells in vitro, limits experimental AAA enlargement in rodent models, and is indirectly associated with reduced clinical AAA risk. We attempted to determin...

BACKGROUND Ruptured abdominal aortic aneurysm (AAA) continues to be associated with high operative mortality. Though survivors can expect to return to a normal life expectancy, their postoperative health related quality of life (HRQoL) remains uncertain. This review examines HRQoL following operative repair of ruptured AAA. METHODS PreMedline, Medline and Embase databases were searched for cl...

OBJECTIVE To study the growth rate and factors influencing progression of small infrarenal abdominal aortic aneurysms (AAA). DESIGN Observational, longitudinal, prospective study. PATIENTS AND METHODS We followed patients with AAA <5 cm in diameter in two groups. Group I (AAA 3-3.9 cm, n = 246) underwent annual ultrasound scans. Group II (AAA 4-4.9 cm, n = 106) underwent 6-monthly CT scans....

We investigated the prostaglandin (PG)E2 pathway in human abdominal aortic aneurysm (AAA) and its relationship with hypervascularization. We analyzed samples from patients undergoing AAA repair in comparison with those from healthy multiorgan donors. Patients were stratified according to maximum aortic diameter: low diameter (LD) (<55 mm), moderate diameter (MD) (55-69.9 mm), and high diameter ...

Objectives: To review the clinical presentations and outcomes of patients with ruptured abdominal aortic aneurysm (AAA) in a regional hospital and its evaluation in the accident and emergency department (AED). Methods: This is a retrospective observational study of patients admitted through the AED with the discharge or post-mortem diagnosis of ruptured AAA from 1st January 2002 to 31st Decembe...

PURPOSE Screening for abdominal aortic aneurysm (AAA) in "men aged over 65 years who have ever smoked" is a recommended policy. To reduce the number of screenings, it may be of value to define subgroups with a higher prevalence of AAA. Since chronic obstructive pulmonary disease (COPD) and AAA are associated with several common risk factors, this study investigates the prevalence of AAA in COPD...

OBJECTIVES Bone marrow-derived vascular progenitor cells (CD34+) are present in human and animal models of abdominal aortic aneurysm (AAA) disease. These preterminally differentiated cells may modulate disease resistance. We examined the influence of variable hemodynamic conditions on progenitor cell localization and differentiation in experimental AAAs. METHODS AND RESULTS Murine AAAs were c...

Mobile hotspots, i.e. Internet access services in moving networks (e.g. vehicular area networks (VAN) and personal area networks (PAN)) bring about new challenging issues. Even if the network mobility (NEMO) basic support protocol has been standardized as a mobility solution by the Internet Engineering Task Force (IETF), to the best of our knowledge, no studies have been conducted in the area o...

Throughput deadlocks were observed when TCP was operated on high-speed networks. This deadlock problem is caused by the interaction of the sender-side and receiverside silly window syndrome avoidance algorithms, because a TCP connection’s Maximum Segment Size is no longer small on high-speed Internet when compared with the send and receive socket buffer sizes. In this paper we propose a new Con...
