Les Jessour dans le Sud-Est tunisien : un système hydro-agricole ancestral dans un milieu aride

Malgré un bilan hydrique largement déficitaire dans le Sud-Est tunisien à climat aride, l'Homme a pu pratiquer l'agriculture en développant la technique des Jessour. Cette technique est confrontée aujourd'hui au risque d'abandon suite aux changements socio-économiques qu'a connus cette région au cours des cinq dernières décennies. Cet article fait le point de l'intérêt hydro-agricole des Jessour et présente les grandes lignes d'une recherche visant à évaluer le bilan hydrique de parcelles utilisant cette technique. Le but est de participer à la conservation de ce savoir-faire ancestral et d'optimiser son utilisation

Analyse de l'événement pluviométrique intense du 11 novembre 2017 et ses effets sur le système hydraulique des Jessour (sud-est tunisien)

Les 11 et 12 novembre 2017, le sud-est tunisien a connu un événement pluviométrique intense. Les quantités tombées ont, dans plusieurs cas, atteint le total annuel. L'analyse climatique de l'événement démontre le rôle de la circulation azonale de secteur est, source des importantes pluies qui touchent la Tunisie orientale en général, associée à une circulation méridienne de secteur nord. Malgré des intensités horaires des averses faibles à modérées, les importantes quantités de pluies ont eu des effets considérables sur le système hydraulique des Jessour. Dans la région de Zammour, sur le plateau du Dahar, 85 % de ces ouvrages hydro-agricoles observés ont été affectés par ces pluies et 34 % sont devenus non fonctionnels suite à une destruction importante qui a touché une ou plusieurs de leurs composantes

Dimethyl Fumarate's Effectiveness and Safety in Psoriasis: A Real-Life Experience During the COVID-19 Pandemic

Introduction: Dimethyl fumarate (DMF) is approved as oral systemic treatment for moderate-to-severe psoriasis. Scarce evidence is available for DMF treatment in psoriatic patients at the time of COVID-19 pandemic. The objective of this study was to assess the long-term effectiveness and safety of DMF monotherapy in moderate-to-severe psoriasis during the COVID-19 pandemic period. Methods: This multicenter, retrospective study included patients with moderate-to-severe psoriasis who had received a 48-week DMF treatment during the COVID-19 pandemic. Selected outcomes were: variation of mean PASI, proportion of patients achieving PASI50 and PASI75, variation of mean PGA and face PGA, genital PGA, scalp PGA, mean itch VAS and mean DLQI. Results: Forty-four patients were enrolled, and four patients became COVID-19 positive during the observation period but did not discontinue DMF therapy. DMF produced a significant improvement of signs and symptoms of psoriasis as expressed by mean PASI variation from 13.07 at baseline to 6.11 at week 48 (p < 0.0001), itch VAS from 3.22 at baseline to 1.18 at week 48 (p < 0.001), PGA from 2.84 at baseline to 1.30 at week 48 (p < 0.0001) and DLQI from 13.09 at baseline to 6.07 at week 48 (p < 0.0001). The percentage of patients who achieved PASI50 and PASI75 was 4.55% at week 4 and 59.09% at week 48 and 0% at week 4 and 22.73% at week 48, respectively. A clinical important decrease of mean PGA score was observed in all subgroups, face psoriasis, genital psoriasis and scalp psoriasis. Adverse events were predictable and manageable. Conclusions: DMF monotherapy is an effective and safe treatment option in moderate-to-severe psoriasis also in patients who develop SARS-CoV-2 infection

Physical activity and dietary habits during pregnancy: effects on glucose tolerance

OBJECTIVES: We designed this study to assess the potential effects of physical activity and dietary habits on glucose tolerance during pregnancy. METHODS: This is an observational study involving 268 women who underwent a 50-g oral glucose challenge test (GCT) at 27±6.9 week of gestation. Plasma glucose level at 1-h GCT ≥ 140 mg/dl was used to define abnormal glucose tolerance (AGT). Physical activity was evaluated using the short form of the International Physical Activity Questionnaire (IPAQ), while for dietary habits we used a food frequency questionnaire linked to a computerised program. RESULTS: One hundred five women had AGT (AGT+) and 163 had normal glucose tolerance (AGT−). There was no difference between the two groups in demographic and clinical data, with the exception of pre-pregnancy BMI and weight gain both higher in AGT+ women. Also, all parameters referring to physical activity energy and diet (Kcal and diet components) were not statistically different between the two groups. After a multivariate analysis, only pre-pregnancy BMI (F-value 9.264, p=0.002) remained an independent predictor of 1-h plasma glucose. CONCLUSIONS: Our study suggests that high pre-pregnancy BMI confers a substantially high risk of AGT, independently of lifestyle during pregnanc

Acute renal failure due to visceral leishmaniasis by Leishmania infantum successfully treated with a single high dose of liposomal amphotericin B

We report a visceral leishmaniasis case in an immunocompetent immigrant with acute renal failure. Parasites were demonstrated in bone marrow, peripheral blood, and kidney samples. A collapsing focal segmental glomerulosclerosis was documented, which was successfully treated with a single infusion of 10 mg/kg liposomal amphotericin B. © 2008 International Society of Travel Medicine
