La Malakoplakie Rétropéritonéale Pseudotumorale

La malakoplakie est une maladie inflammatoire granulomateuse chronique, qui affecte généralement le tractus génito-urinair e et moins fréquemment les autres sites tels que le rétropéritoine et le tractus gastro- intestinal. L’origine infectieuse associée à un déficit dans la digestion macrophagique des bactéries est la théorie physiopathologique la plus soutenue. Sa définition est anatomopathologique. Les auteurs rapportent un cas de malakoplakie rétropéritonéale pseudotumorale chez un patient sous corticothérapie au long cours admis aux urgences pour une masse douloureuse et fébrile du flanc gauche. Les explorations radiologiques étaient en faveur d’une collection abcédée nécessitant un drainage chirurgical en urgence. L’examen histologique des prélèvements réalisés au niveau de la graisse rétropéritonéale révélait une inflammation granulomateuse faite d’histiocytes dénommés cellules de Von Hansemann, renfermant des granulations pathognomoniques de Michaelis-Gutmann. Le patient a été mis sous traitement médical à base de ciprofloxacine avec bonne évolution clinique et radiologique.Mots clés : Malakoplakie; Michaelis-Gutmann; Rétropéritoine

Migration Intravésicale du Dispositif Intra-Utérin à Propos de Cinq Cas

La migration intravésicale du dispositif intra-utérin (DIU) par perforation utérine est une complication rare. Dans cette étude rétrospective monocentrique, nous présentons notre expérience de 5 cas colligés au sein de notre établissement entre 2004 et 2009. L’âge moyen de nos patientes est de 39 ans (32-48 ans). La symptomatologie clinique révélatrice était dominée par le syndrome irritatif vésical. Le diagnostic a été évoqué sur le couple écho/AUSP, puis confirmé par la cystoscopie. Le traitement a consisté en une lithotritie balistique du calcul avec extraction du stérilet par voie endoscopique chez 4 patientes et extraction chirurgicale chez une seule.Mots clés : Calcul vésical, dispositif intra-utérin, lithotritie balistique, migration

Cantharidin Poisoning due to Blister Beetle Ingestion in Children : Two case reports and a review of clinical presentations

Cantharidin is an intoxicant found in beetles in the Meloidae (Coleoptera) family. Ingestion may result in haematemesis, impaired level of consciousness, electrolyte disturbance, haematurea and renal impairment. Here, we report two paediatric cases of meloid beetle ingestion resulting in cantharidin poisoning and the clinical presentation of the ensuing intoxication

Renal oncocytoma: experience of Clinical Urology A, Urology Department, CHU Ibn Sina, Rabat, Morocco and literature review

Renal oncocytoma is a rare and benign renal tumor. Only few cases have been reported in Moroccan populations. In the present study, we reportour experiences in the diagnosis, management and follow-up of this disease. We report on six cases of renal oncocytoma indentified between 1990 and 2008 in the urology department of “CHU Ibn Sina” in Rabat. These six cases are listed among 130 kidney tumors reported during the study period. We assess the clinical, radiological and therapeutic features of the patients and we review literature. Six cases of renal oncocytoma,representing 4.6% of all primitive kidney tumors treated in our institution during the study period. The mean age was 53 ±9.7 years (range 34 to61 years). One patient was asymptomatic at presentation, five patients (83%) had flank pain and two (33%) had macroscopic hematuria. Thetumor was right sided in 4 cases (66%) and left sided in 2 cases (33%). All patients underwent CT scan which showed, in three cases, a centrallylocated stellate area of low attenuation. The clinical suspicion of  oncocytoma was made preoperatively in only 3 patients by imaging studies, but the suspicion of renal cell carcinoma persist and all patients were treated with radical nephrectomy. Definitive diagnosis was made in all cases postoperatively. All the tumors were well circumscribed but unencapsulated. The mean tumor size was 8,75±2,04 cm. Four patients were classified at stage pT2 and two at stage p T1. Most of the pathological features in our patients were typical of this entity.  Predominant cell type was a typical oncocytoma with general low mitotic activity. No extension to peri-nephric fat tissue or lymphovascular invasion was observed. After a mean follow-up of 36 months (range 26-62 months), there was neither recurrence nor death from oncocytoma. Accordingly, the disease-specific survival was 100%. Renal oncocytoma has a benign clinical course with excellent long-term outcomes. In our series, it happened mostly in females and is more frequently symptomatic. Although radical nephrectomy is the usual treatment, a conservative approach should be considered whenever there are signs of clinical and radiological presumptions.Key words: Renal oncocytoma, tumor, diagnosis, treatmen

Séminome Spermatocytaire: à Propos d’un Cas et Revue de La Littérature Spermatocytic Seminoma

Le séminome spermatocytaire est une tumeur rare, représentant moins de 2% des cancers du testicule, survenant essentiellement chez le sujet âgé. Nous rapportons une nouvelle observation d’un patient âgé de 48 ans. La tumeur se présentait comme une prolifération de cellules en nappescompactes, avec 3 types cellulaires, des cellules de petite taille, des cellules intermédiaires et des grandes cellules. Il n’a été retrouvé ni contingent sarcomateux, ni séminome classique. L’analyse en immun histochimie n’a retrouvé aucune expression des cellules tumorales pour les anticorpsclassiques testés, notamment l’Ac anti PLAP et les marqueurs lymphoïdes. Le séminome spermatocytaire doit être reconnu, car son évolution est très favorable et ne nécessite qu’une simple orchidectomie, en l’absence d’un exceptionnel contingent sarcomateux ou de métastase où une chimiothérapie s’impose

Convection heat transfer with water based mango bark nanofluids

Numerous studies reveal that the heat transfer capability of thermal systems has been significantly enhanced with the use of nanofluids. On the other hand, the hazardous nature of the nanoparticles is evident. Recent studies clearly indicate that the nanoparticles affect the human health as well as the environment. Therefore environmentally safe bio-nanofluids are currently under investigation. In this study, a novel heat transfer fluid with bio-nanomaterial is prepared and its natural convection heat transfer characteristics are studied. The bionanomaterial considered in this study is powdered mango bark. A two-step process is employed to prepare stable nanofluids. The effect of particles concentration, the temperature difference between the hot and cold side, and Rayleigh number on the natural convection heat transfer process is studied. The experimental results show that the natural convection process is deteriorated with the addition of mango nanoparticles in deionized water.Papers presented at the 13th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Portoroz, Slovenia on 17-19 July 2017 .International centre for heat and mass transfer.American society of thermal and fluids engineers

Profiling a decade of information systems frontiers’ research

This article analyses the first ten years of research published in the Information Systems Frontiers (ISF) from 1999 to 2008. The analysis of the published material includes examining variables such as most productive authors, citation analysis, universities associated with the most publications, geographic diversity, authors’ backgrounds and research methods. The keyword analysis suggests that ISF research has evolved from establishing concepts and domain of information systems (IS), technology and management to contemporary issues such as outsourcing, web services and security. The analysis presented in this paper has identified intellectually significant studies that have contributed to the development and accumulation of intellectual wealth of ISF. The analysis has also identified authors published in other journals whose work largely shaped and guided the researchers published in ISF. This research has implications for researchers, journal editors, and research institutions

Factor structure of Urdu version of the flourishing scale

Background: A great deal of research has been carried out on the assessment of the eudaimonic perspective of psychological well-being and the hedonic perspective of subjective well-being. The Flourishing Scale (FS) has been extensively used in research and practice, as it assesses the fundamental aspects of social psychological functioning. Nevertheless, the psychometric properties of Urdu versions of eudaimonic measures, such as the FS, have not yet been ascertained. The translation and validation of the FS in the Urdu language was not available, and hence this study was planned with the aim to validate the Urdu version of the FS. Methods: We assessed the psychometric properties of the FS in a sample of adults aged 18 years and above in Pakistan (N = 130) using exploratory factor analysis based on principal component analysis with varimax rotation and confirmatory factor analysis. Results: The exploratory factor analysis confirmed the unidimensional nature of the 8-item FS. We assessed that the Urdu version of the FS showed a high internal consistency reliability (α = 0.914) with a significant intraclass correlation coefficient (ICC), p < 0.001). In our study, the Kaiser–Mayer–Olkin value was 0.915 with a chi-square test value (χ2) of 637.687, and Bartlett's test of sphericity was significant (df = 28, p < 0.001). The intraclass correlation coefficients (ICCs) at test–retest for all domains were statistically significant (p < 0.001) and showed excellent agreement for all the items. The revised confirmatory factor analysis revealed a good-fit model, but with item 8—“People respect me”—removed due to its lower factor loading. Conclusions: The findings suggest that the FS is a psychometrically sound instrument for assessing social psychological functioning among adults in Pakistan. Therefore, the validated Urdu version of the FS may be used in future studies of well-being in clinical psychology and positive psychology
