[Degradation products of fibrinogen in synovial fluid].
No full textThe fibrin/fibrinogen degradation products were measured in 24 synovial fluids sampled from patients with knee joint effusion. It has been observed that they are increased in synovial fluid involved in inflammatory processes. Their presence and concentration seem to be related to the control of local inflammation

Axillary vein technique for pacemaker and implantable defibrillator leads implantation: A safe and alternative approach?
No full textDifferent methods for venous access are used for permanent pacemaker or implantable cardioverter defibrillator (ICD), of which subclavian vein puncture technique is the most widely practised. Although this approach is relatively easy to learn, quick and offers high success rates, it may be associated with potential serious acute complications including pneumothorax, emopneumothorax, brachial plexus injury and longer-term complications such as lead fracture, loss of lead insulation and subclavian crush syndrome especially in young patients with ICD leads. Axillary vein approach seems to be a favourable technique not only for the prevention of acute complications but also to reduce lead failure including lead insulation and lead fracture prevention with a consequently better long-term lead survival compared with the classical subclavian approach. Although randomized studies are lacking, recent reports not only evaluated the safety and effectiveness of new fluoroscopic axillary venous puncture technique, but also compared it with the conventional intrathoracic subclavian venous puncture technique for the implantation of leads in permanent pacing. Various techniques of axillary vein puncture have been proposed ranging from a blind percutaneous puncture to the use of different tools such as contrast venography and ultrasound. In this article, we report a case of subclavian crush syndrome, the use of a modified Bellot's technique of axillary vein puncture that we currently use and the potential benefits of axillary vein puncture for pacemaker and ICD leads implantation compared with subclavian approach to avoid acute and long-term lead complications
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
