    Notizen: Abstract The existence of the fourth perforating artery of Paturet [7], a collateral branch of the superficial femoral artery in its lower third, is the subject of much debate. This artery has so far only been the subject of radio-anatomic descriptions based on arteriographies carried out within the context of arteriopathy of the lower limbs. We present a descriptive anatomic study of this artery based on 14 observations on 32 dissections. Three types of approach were carried out: exposure of the artery of the femoral quadriceps muscle up to its ending in the vastus lateralis; a lateral “orthopaedic” approach to the lower third of the femur; and a “vascular” approach by a medial incision to the femoro-popliteal axis in the lower third of the thigh. Its main relations are described, passing in front of the superficial femoral vein and then behind the femur before ending at the vastus lateralis muscle. These relations explain the possibility of anastomoses with collateral or terminal branches of the deep femoral artery (vastus lateralis artery, third perforating artery). The fourth perforating artery of Paturet [7] must be protected in traumatologic and vascular surgery. It is the main collector of vascular anastomoses between the deep femoral artery and the femoro-popliteal axis in the event of proximal occlusion of the superficial femoral artery. Its removal, in such a case, can aggravate an underlying arteriopathy.

    Beschreibung / Inhaltsverzeichnis: Résumé L'existence de la quatrième artère perforante de Paturet [7], branche collatérale de l'artère fémorale superficielle dans son tiers distal, est controversée. Cette artère n'a fait l'objet que de descriptions radio-anatomiques sur des artériographies réalisées dans un contexte d'artériopathie des membres inférieurs. Nous présentons une étude anatomique descriptive de cette artère observée dans 14 cas sur 32 dissections. Trois types de voie d'abord ont été utilisés : exposition de l'artère du muscle quadriceps fémoral jusqu'à sa terminaison dans le muscle vaste latéral, voie d'abord latérale « orthopédique » du tiers distal du fémur, voie d'abord vasculaire par incision médiale de l'axe fémoro-poplité au tiers inférieur de la cuisse. Ses rapports principaux sont décrits, passant en avant de la veine fémorale superficielle puis en arrière du fémur avant de se terminer dans le muscle vaste latéral. Ces rapports expliquent les anastomoses possibles avec les branches collatérales et terminales de l'artère profonde de la cuisse (artère du muscle vaste latéral, troisième artère perforante). La quatrième artère perforante de Paturet [7] doit être préservée en traumatologie et en chirurgie vasculaire. En effet, elle est le collecteur principal des anastomoses vasculaires entre l'artère profonde de la cuisse et l'axe fémoropolité en cas d'occlusion proximale de l'artère fémorale superficielle. Son sacrifice peut, dans ce cas, décompenser une artériopathie sous-jacente.

    Notizen: Summary In a previous work, we had found that anti-B lymphocyte antibodies exist in rheumatoid arthritis. To investigate whether these antibodies were directed against surface immunoglobulins or not we have investigated if RA sera could recognize similar structures on other targets such as platelets (on which immunoglobulins and immune complexes are present) by a new ELISA method. No IgG antiplatelet antibody was found in 20 RA sera. But 7 out these 20 RA sera had IgM antiplatelet antibodies when tested on platelets from 5 donors. The comparison of the positivities of these sera on B lymphocytes and platelets from the same donors showed a statistically significant reverse (X2=20,008, p〈0.0001) correlation. The target antigen and the meaning of these IgM antiplatelet antibodies, which seem to be associated with severe RA, is still under investigation.

    Notizen: Summary The results of a previous study led us to believe that the association of HLA-DR4 and rheumatoid arthritis could be of particular interest in our region. In this work we typed 58 caucasoid patients in the Marseilles area by microlymphocytotoxicity assay in B-cells. HLA-DR4 was found to be at the same level as that observed by the authors in the 8th Workshop of histocompatibility (1980) (X2: 32.36, P (0.001) and very high in the seropositive patients (61.5 per cent). No correlation with sex was observed. We again found a low frequency of HLA-DR4 (15.8 per cent) in our controls.
