Background MOSKI KIT® is a fun tool designed to interest children for prevention and management of malaria. This study was carried out with the objective to assess the short- and long-term impacts of this tool on the knowledge, attitudes, and practices of school children, and on the transmission of the knowledge received at the household level as well. Method The study took place in elementary schools in the city centre (with relatively low endemicity) and in the Niayes area (at high risk of anopheline and malaria) in the Dakar region of Senegal. The various schools chosen for this study were divided into an intervention group and a control group. The intervention schools were also divided into two subgroups, a full package subgroup and another partial package. During this study three surveys were conducted, the first one before exposure to the MOSKI KIT®, the second one a week later and the third a year later. For the control schools only one survey was conducted and at the same time than the third for the intervention schools. Two household surveys (a week and a year after exposure) were also conducted for the intervention schools against one for the control schools. Results Before sensitization, the proportion of school children with a grade above or equal to the average was 50% for the complete package subgroup (CPS) and 53% for the partial package subgroup (PPS). A week later, these proportions were 69% and 71%, respectively for the complete and PPSs. A year later, they were 99.4% for the CPS, 98.1% for the PPS and 99.5% for the control group; The number of children who spoke to their parents about malaria was greater in intervention schools than that of control schools. They were 46.63% and 32.58%, respectively in intervention and control schools. Conclusion The MOSKI KIT, has enabled an increase of the knowledge of school children about malaria in the short term and favoured its retention in the long term. However, its impact was not felt on their attitudes and practices.

ObjectivesTo evaluate the interobserver reliability and value of diffusional kurtosis imaging (DKI) in the assessment of uterine tumors compared with those of conventional diffusion-weighted imaging (DWI).MethodsThis retrospective study was approved by our institutional review board, which waived the requirement for informed consent. Fifty-eight women (mean age: 55.0 ± 13.6 years; range: 30–89 years) with suspected malignant uterine tumors underwent 3-T magnetic resonance imaging using DKI and DWI. Twelve had coexisting leiomyoma. Two observers analyzed region-of-interest measurements of diffusivity (D), kurtosis (K), and the apparent diffusion coefficient (ADC) of uterine lesions and healthy adjacent tissues. Interobserver agreement was evaluated using the intra-class correlation coefficient (ICC). The mean values were compared using one-way analysis of variance with a post-hoc Tukey’s honestly significant difference test. The diagnostic accuracy of D and ADC in differentiating malignant tumors from benign leiomyomas was analyzed using receiver operating characteristic (ROC) analysis.ResultsThe ICCs between the two observers in evaluating D, K, and the ADC of the malignant tumors were higher than 0.84, suggesting excellent interobserver agreements. The mean D (×10−3 mm2/s) of uterine cancers (1.05 ± 0.41 and 1.09 ± 0.40 for observers 1 and 2, respectively) were significantly lower than those of leiomyoma (1.40 ± 0.37 and 1.56 ± 0.33, respectively; P < 0.05), healthy myometrium (1.72 ± 0.27 and 1.69 ± 0.30, respectively; P < 0.001), and healthy endometrium (1.53 ± 0.35 and 1.42 ± 0.37, respectively; P < 0.005). There was no significant difference in the area under the ROC curve between D and ADC. The mean K of uterine cancers (0.88 ± 0.28 and 0.90 ± 0.23, respectively) were higher than those of myometrium (0.72 ± 0.10 and 0.73 ± 0.10, respectively; P < 0.001), healthy endometrium (0.65 ± 0.13 and 0.60 ± 0.18, respectively; P < 0.001), and leiomyoma (0.76 ± 0.14 and 0.77 ± 0.16, respectively; not significant, P > 0.1).ConclusionsInterobserver agreements in evaluating D, K, and ADC were moderate to excellent. D performed equally to conventional DWI in differentiating between benign and malignant uterine lesions. The mean K of malignant uterine lesions was significantly higher than that of non-tumorous myometrium or endometrium.

IntroductionLe pied diabétique se définit comme l'ensemble des manifestations trophiques du pied survenant chez le diabétique par atteinte nerveuse, artérielle et ou infectieuse. Le pied diabétique est un problème majeur de santé publique à l’échelle mondiale avec un taux d'amputation de membres inférieurs très élevé. L’écho-doppler artériel des membres inférieurs est de nos jours incontournable dans la prise en charge du pied diabétique. Le but de cette étude est de montrer la place prépondérante qu'occupe l’écho-doppler artériel dans le bilan lésionnel du pied diabétique.MéthodesNous avons mené une étude rétrospective monocentrique incluant 46 patients sur une période de 24 mois, de mars 2012 à mars 2014 à l'hôpital Saint-Jean de Dieu, un des deux hôpitaux de référence de la région de Thiès, doté depuis juillet 2011 d'un centre moderne de traitement du diabète et des maladies cardio-métaboliques (Diabcarmet). Dans les critères d'inclusion, nous avons sélectionné tous les patients diabétiques adressés pour un écho-doppler artériel des membres inférieurs dans le cadre d'une prise en charge du pied diabétique. Etaient exclus de l’étude, les patients artéritiques non-diabétiques et les patients diabétiques asymptomatiques référés pour un bilan écho-doppler de routine.RésultatsLe sex-ratio était de 1.42 (27 hommes pour 19 femmes). L’âge moyen des patients était de 62,86 ans avec des extrêmes de 23 et 88 ans. 60% des patients (n=28) étaient âgés entre 50 et 70 ans. Le diabète de type 2 était retrouvé chez 95% des patients (n=44) alors que le diabète de type 1 représentait 5% (n=2). La moyenne d’évolution du diabète était estimée à 8 ans, avec des extrêmes de 2 et 20 ans. On notait une atteinte du pied droit chez 24 patients, une atteinte du pied gauche chez 18 patients et une atteinte bilatérale chez 4 patients. La plupart du temps, les lésions du pied diabétique survenaient sur un terrain de diabète déséquilibré (95%). Cliniquement, ces lésions étaient dominées par la gangrène infectieuse du pied (43.47%), l'abolition des pouls tibiaux et pédieux (17.4%), la gangrène infectieuse des orteils (13.07%), la gangrène mixte du pied (4.34%) et le mal perforant plantaire (4.34%). Sur le plan échographique, vingt-six patients ne présentaient aucune anomalie hémodynamique significative, même si sur le plan morphologique la médiacalcose était retrouvée chez tous nos patients (n=46). Les autres lésions morphologiques et hémodynamiques artérielles étaient dominées par la sténose serrée de l'artère fémorale superficielle chez 6 patients soit 13.04%, les sténoses des artères tibiales antérieures et postérieures chez 4 patients (6.52%) et l'association de plusieurs lésions artérielles chez 4 patients (8.7%). Le taux d'amputation, dans notre série, était de 21.7%.ConclusionLe pied diabétique est une complication potentiellement grave du diabète, en Afrique sub-saharienne du fait d'un fort taux d'amputation de membre. L’écho-doppler artériel des membres inférieurs est un moyen d'imagerie non irradiant et non invasif indispensable dan...

Introduction: The gold of this work was to study the clinical and therapeutic management aspects of renal oncocytoma in our settings. Our Observations: Case 1: there was a 44-year-old patient being followed up for a urinary tract infection due to Escherichia coli. The urological CT-scan showed a tumor-like process on a horseshoe kidney. Radical nephrectomy was performed and the histology report confirmed renal oncocytoma; Case 2: it involved a 62-year-old hypertensive patient. Clinical examination revealed a grade II cystocele and medical imaging showed a tumor-like mass at the lower pole of the right kidney. Radical nephrectomy was performed and histology was concluded in favor of renal oncocytoma; Case 3: there was a 64-year-old patient monitored for chronic renal failure and on dialysis for 6 months. Imaging showed a heterogeneous mass developing from the kidney. Histology and immunohistochemistry confirmed renal oncocytoma. Conclusion: Imaging could contribute greatly to preoperative diagnosis. However, there is a need to think about renal oncocytoma when evaluating kidney tissue masses.
