SYNDROME DE LâARTERE POPLITEE PIEGEE : UNE CAUSE RARE DE CLAUDICATION INTERMITTENTE DU SUJET JEUNE
The syndrome of the trapped pop1ity artery appears in the young adult like a limping of the calf and or foot. Anatomical anomalies relating to insertions of the internai Twin muscle primarily. The diagnosis is suspect on Doppler echography, showing positional compression, change of direction of the poplitĂ©e artery, or only the existence of an abnormal fascicule of muscle fibres between artery and poplity vein. Angio IRM can replace the conventional assessment arteriographic. The treatment of extrinsic compression must avoid the constitution of parietal lesions and thromboses if they are installed, the suppression of the anatomical anomaly must be associated a segmentary revascularisation in autogenous venous material. Our patient is a young patient who consulted for an intermittent limping of effort of the right calf. The peripheral pulses were present, just as arterial the Doppler echo and the angio scanner of the hollow poplity showed the insertion of a beam of the internal  twin between the artery and the vein poplity. The arterial Ă©chodoppler and the IRM are according to certain authors the only essential examinations with the positive and differential diagnosis of the syndrome of the trapped pop1ity artery and will make it possible to eliminate from other differential diagnoses: pop1ity athĂ©romating and the early athĂ©rome, disease of Burger or thromboangĂ©ite obliterating, the aneurisms poplities and the cysts adventitiels of the poplity artery. The treatment is always surgical and must be early. It includes/understands the lifting of the trap associated with the need with an arterial gesture of revascularisation. For the authors, the permeability to short and long-term was better for the patients among whom one practised a section of the musculo-tendineux beam being wrong compared to the patient which profited from a gesture of  vascular restoration.Le syndrome de lâartĂšre poplitĂ©e piĂ©gĂ©e se manifeste chez lâadulte jeune comme une claudication du mollet et ou du pied. Les anomalies anatomiques concernant essentiellement les insertions du muscle Jumeau interne. Le diagnostic est suspectĂ© sur lâĂ©chographie doppler, montrant la compression positionnelle, le changement de direction de lâartĂšre poplitĂ©e, ou seulement lâexistence dâun faisceau musculaire anormal entre artĂšre et veine poplitĂ©e. Lâangio IRM peut remplacer le bilan artĂ©riographique conventionnel. Le traitement de la compression extrinsĂšque doit Ă©viter la constitution de lĂ©sions pariĂ©tales et de thromboses si elles sont installĂ©es, la suppression de lâanomalie anatomique doit ĂȘtre associĂ©e Ă une revascularisation segmentaire en matĂ©riel veineux autogĂšne. Notre patient est un malade jeune qui a consultĂ© pour une claudication intermittente dâeffort du mollet droit. Les pouls pĂ©riphĂ©rique Ă©taient prĂ©sents, de mĂȘme que lâĂ©cho doppler artĂ©riel et lâangio scanner du creux poplitĂ© montraient lâinsertion dâun faisceau du jumeau interne entre lâartĂšre et la veine poplitĂ©. LâĂ©chodoppler artĂ©riel et lâIRM sont selon certains auteurs les seuls examens indispensables au diagnostic positif et diffĂ©rentiel du syndrome de lâartĂšre poplitĂ©e piĂ©gĂ©e et vont permettre dâĂ©liminer dâautres diagnostics diffĂ©rentiels : poplitĂ©e athĂ©romateuse et lâathĂ©rome prĂ©coce, maladie de Buerger ou thromboangĂ©ite oblitĂ©rante, les anĂ©vrysmes poplitĂ©s et les kystes adventitiels de lâartĂšre poplitĂ©e. . Le traitement est toujours chirurgical et doit ĂȘtre prĂ©coce. Il comprend la levĂ©e du piĂšge associĂ© au besoin Ă un geste de revascularisation artĂ©riel. Pour les auteurs, la permĂ©abilitĂ© a court et Ă long terme Ă©tait meilleure pour les malades chez qui on a pratiquĂ© une section du faisceau musculo-tendineux aberrant par rapport au patient qui ont bĂ©nĂ©ficiĂ© dâun geste de restauration vasculaire
Exploring ripening of nanocapsules and emulsions in parenteral nutritional mixtures by experimental design
International audienceLipid nanocapsules based on vegetal oils (vo-LNC) can be prepared and used to allow both the easy incorporation of oils in the aqueous phase and the stability of mixtures for parenteral nutrition. In this context of use, vo-LNC was shown an interesting process of ripening. To explore this ripening process, experimental design was used. The same mixture design was performed for both the incorporation of lipids by vo-LNC as by emulsion. The responses chosen for the experimental design was the average size and zeta potential of both. As expected, vo-LNC and emulsion were affected at different level by the ripening process. This indicates clearly that vo-LNC would permit the early incorporation of lipids in parenteral nutrition admixtures without any risk of instability and can be safely administered for parenteral use.</p

The effect of dietary and/or cosmetic argan oil on postmenopausal skin elasticity
Kenza Qiraouani Boucetta,1 Zoubida Charrouf,2 Hassan Aguenaou,3 Abdelfattah Derouiche,4 Yahya Bensouda1 1Research Team on Formulation and Biopharmacy, Research Center for Drug, Faculty of Medicine and Pharmacy, Mohammed V University, Rabat, Morocco; 2Faculty of Sciences, Mohammed V University, Rabat, Morocco; 3Mixed Unit of Research in Nutrition, ITU / CNESTEN, Ibn Tofail University, Kenitra, Morocco; 4Faculty of Sciences, Hassan II University, Casablanca, Morocco Background: During menopause, the decrease of estrogenic secretion induces the disruption of skin functioning, thus causing the decline in skin elasticity characteristic of skin aging. The purpose of this study was to evaluate in postmenopausal women the effect of daily consumption and/or application of argan oil on skin elasticity.Materials and methods: Sixty postmenopausal women consumed butter during the stabilization period and were randomly divided into two groups for the intervention period: the treatment group of 30 participants received dietary argan oil, the control group of 30 participants received olive oil, and both groups applied cosmetic argan oil in the left volar forearm during a 60-day period. Assessments of skin elasticity parameters, ie, the three R-parameters (R2 or gross-elasticity of the skin, R5 or net elasticity of the skin, and R7 or biological elasticity), and the resonance running time (RRT) at both volar forearms of the two groups were performed during three visits: before starting oils consumption and application, after 30 days of oils consumption and application, and after 60 days of oils consumption and application.Results: The consumption of argan oil led to a significant increase of gross-elasticity of the skin (R2) (P<0.001), net elasticity of the skin (R5) (P<0.001), biological elasticity (R7) (P<0.001), and a significant decrease of RRT (P=0.002). The application of argan oil led to a significant increase of gross-elasticity of the skin (R2) (P<0.001), net elasticity of the skin (R5) (P<0.001), biological elasticity (R7) (P=0.001), and a significant decrease of RRT (P<0.001).Conclusion: Our findings suggest that the daily consumption and/or topical application of argan oil have an anti-aging effect on the skin demonstrated by the improvement of skin elasticity, characterized by an increase of R-parameters (R2, R5, and R7) and a decrease of RRT.Keywords: postmenopausal women, argan oil, skin elasticit
