Atteinte urinaire et pseudo-obstruction intestinale révélatrice d’un lupus érythémateux systémique à propos d’une observation

Introduction : Le lupus érythémateux systémique est une connectivite fréquente chez les femmes en activité génitale. Au cours du lupus érythémateux systémique, la pseudo-obstruction intestinale est l’une des graves complications rares. Ainsi l’objectif de cet article est de présenter un cas clinique d’atteinte urinaire et pseudo-obstruction intestinale révélatrice d’un lupus érythémateux systémique. Observation : Une patiente âgée de 28 ans mariée, de Nationalité Guinéenne admise pour une diarrhée fébrile, asthénie, météorisme, associée à des douleurs articulaire et abdominale nécessitant une consultation et des bilans sans succès.Une échographie abdominale qui objective un épaississement diffus de la paroi colique et des anses grêles ainsi qu’une ascite de moyenne abondance. La coloscopie révèle un aspect inflammatoire spécifique de la muqueuse iléale. Conclusion : La pseudo-obstruction intestinale peut être inaugurale ou concomitante du lupus érythémateux systémique

Integrated use of fertilizer micro-dosing and Acacia tumida mulching increases millet yield and water use efficiency in Sahelian semi-arid environment

Limited availability of soil organic amendments and unpredictable rainfall, decrease crop yields drastically in the Sahel. There is, therefore, a need to develop an improved technology for conserving soil moisture and enhancing crop yields in the Sahelian semi-arid environment. A 2-year field experiment was conducted to investigate the mulching effects of Acacia tumida pruning relative to commonly applied organic materials in Niger on millet growth, yields and water use efficiency (WUE) under fertilizer micro-dosing technology. We hypothesized that (1) A. tumida pruning is a suitable mulching alternative for crop residues in the biomass-scarce areas of Niger and (2) combined application of A. tumida mulch and fertilizer micro-dosing increases millet yield and water use efficiency. Two fertilizer micro-dosing options (20 kg DAP ha−1, 60 kg NPK ha−1) and three types of organic mulches (millet straw, A. tumida mulch, and manure) and the relevant control treatments were arranged in factorial experiment organized in a randomized complete block design with four replications. Fertilizer micro-dosing increased millet grain yield on average by 28 %. This millet grain yield increased further by 37 % with combined application of fertilizer micro-dosing and organic mulch. Grain yield increases relative to the un-mulched control were 51 % for manure, 46 % for A. tumida mulch and 36 % for millet mulch. Leaf area index and root length density were also greater under mulched plots. Fertilizer micro-dosing increased WUE of millet on average by 24 %, while the addition of A. tumida pruning, manure and millet increased WUE on average 55, 49 and 25 %, respectively. We conclude that combined application of micro-dosing and organic mulch is an effective fertilization strategy to enhance millet yield and water use efficiency in low-input cropping systems and that A. tumida pruning could serve as an appropriate mulching alternative for further increasing crop yields and water use efficiency in the biomass-scarce and drought prone environment such as the Sahel. However, the economic and social implications and the long-term agronomic effects of this agroforestry tree in Sahelian millet based system have to be explored further

Results analysis and validation - D5.3

This deliverable describes the validation processes followed to assess the performance of the algorithms and protocols for the operator governed opportunistic networking as defined in the OneFIT Project. Therefore, this document includes the description of the set-up of the different validation platforms, the design of the test plans for each one of them, and the analysis of the results obtained from the tests. A per-scenario approach rather than a per-platform approach has been followed, so an additional analysis has been performed, gathering the results related to each scenario, in order to validate the premises stated to each one of them. The OneFIT concept has been therefore validated for all foreseen business scenarios
