Informatique décisionnelle et management de la performance de l'entreprise.

Les premières applications dans les entreprises des outils informatiques d’aide au pilotage et à la décision, désormais appelés «Business Intelligence», datent du début des années quatre-vingt-dix ; les «Executive Information Systems» étaient à l’origine réservés à l’information des dirigeants. La banalisation dans les entreprises, vers le milieu de la décennie quatre-vingt-dix, des technologies de «datawarehouse» et de «data mart» a accru la possibilité de développer des systèmes d’information organisant les données de façon facilement accessible et appropriée à la prise de décisions et les représentant de manière intelligente au travers d’outils spécialisés tournés vers l’analyse multidimensionnelle avec notamment les bases «OLAP». Ce qui a pour effet de faciliter le management de la performance de l’entreprise. Le présent article examine d’abord la question de l’apport des technologies de l’information au processus décisionnel. Puis, il montre tout l’intérêt d’une architecture décisionnelle fondée sur un entrepôt de données pour le management de la performance. Plus précisément, il tente de montrer comment l’informatique décisionnelle facilite la modélisation d’une performance multidimensionnelle pour en permettre le pilotage au travers d’un des modèles possibles de sa représentation : le tableau de bord prospectif.Décision, Information, Informatique décisionnelle, management de la performance, performance, pilotage, tableau de bord prospectif

Vulvar lactating adenoma associated to a fibroadenoma: common neoplasms in an uncommon site

Ectopic breast tissue is defined as glands located outside of the breast. Ectopic breast tissue should be excised because it may develop benign (fibroadenoma) or malignant pathologic processes. Less than forty cases of fibroadenomas have been reported in the literature. Although lactation changes can occur, lactating adenoma in the vulva are extremely rare. Only four cases have been reported. We report a case of a young woman who presented with vulvar mass during her lactation. The mass was excised, and histology confirmed vulvar lactating adenoma associated with fibroadenoma. This is the first case of vulvar heterotopic breast lesion associating lactating adenoma and fibroadenoma.Pan African Medical Journal 2012; 13:4

Desmoplastic infantile ganglioglioma

The term desmoplastic infantile ganglioglioma was coined by VandenBerg et al. in 1987. In their first report these authors referred to a rare, distinct brain tumor. About 60 cases of desmoplastic infantile ganglioglioma have been described in the literature since its first description. We report a case of a 6-year-old girl who was admitted for seizure without family history. Magnetic resonance imaging scan showed a hypodense area in the right temporal region. A right temporal craniotomy was performed and the tumor was excised. The pathologic examination revealed the diagnosis of desmoplastic infantile ganglioglioma

A Primary Testicular Diffuse Large B-cell Lymphoma Belonging to the Germinal Center B-cell-like Group

Testicular lymphoma was first reported by Malassez and Curling in 1866. Primary testicular lymphoma constitutes only 1 - 7% of all testicular neoplasms and less than 1% of all non Hodgkin lymphoma. The authors report a new case of primary testicular lymphoma and highlight its diagnostic and therapeutic challenge. We report the case of a 26-year old man without a particular past medical history, who presented with a painful right testicular swelling that he has noticed for several weeks. Radiological findings consisted in multiple hypoechoic masses that corresponded in histological examination to a diffuse intratubular lymphomatous infiltration situated away from the spermatic cord, the epididymis, ductuli efferentes and rete testis. Immunohistochemical study showed positivity for leukocytic common antigen (CD45), B-cell marker (CD20) and bcl 6. The patient underwent full staging for lymphoma showing no evidence of extra-testicular involvement by lymphoma and no lymph nodes. The diagnosis of stage I primary testicular large B-cell lymphoma of germinal center B-cell-like group was made. The patient is now treated by chemotherapy. Primary testicular lymphoma is a rare tumour whose diagnosis is based on histological findings. There are non consensual etiological or predisposing factors. Treatment modalities consist in surgical excision, chemotherapy and radiation therapy but the accurate procedures are not standardized. Factors that have been linked to more favorable outcomes include younger patient age, localized disease, presence of sclerosis at pathologic analysis, smaller tumour size, lower histological tumor grade and lack of epididymal or spermatic cord involvement

Discovering microbiota and volatile compounds of surströmming, the traditional Swedish sour herring

none13noIn this study, the microbiota of ready-to-eat surströmming from three Swedish producers were studied using a combined approach. The pH values of the samples ranged between 6.67±0.01 and 6.98±0.01, whereas their aw values were between 0.911±0.001 and 0.940±0.001. The acetic acid concentration was between 0.289±0.009 g/100 g and 0.556±0.036 g/100 g. Very low concentrations of lactic acid were measured. Viable counting revealed the presence of mesophilic aerobes, mesophilic lactobacilli and lactococci as well as halophilic lactobacilli and lactococci, coagulase-negative staphylococci, halophilic aerobes and anaerobes. Negligible counts for Enterobacteriaceae, Pseudomonadaceae and total eumycetes were observed, whereas no sulfite-reducing anaerobes were detected. Listeria monocytogenes and Salmonella spp. were absent in all samples. Multiplex real-time PCR revealed the absence of the bont/A, bont/B, bont/E, bont/F, and 4gyrB (CP) genes, which encode botulinic toxins, in all the samples analyzed. Metagenomic sequencing revealed the presence of a core microbiota dominated by Halanaerobium praevalens, Alkalibacterium gilvum, Carnobacterium, Tetragenococcus halophilus, Clostridiisalibacter, and Porphyromonadaceae. Psychrobacter celer, Ruminococcaceae, Marinilactibacillus psychrotolerans, Streptococcus infantis and Salinivibrio costicola were detected as minority OTUs. GC-MS analysis of volatile components revealed the massive presence of trimethylamine and sulfur compounds. Moreover, 1,2,4-trithiolane, phenols, ketones, aldehydes, alcohols, esters and long chain aliphatic hydrocarbons were also detected. The data obtained allowed pro-technological bacteria, which are well-adapted to saline environments, to be discovered for the first time. Further analyses are needed to better clarify the extent of the contribution of either the microbiota or autolytic enzymes of the fish flesh in the aroma definition.restrictedLuca Belleggia, Lucia Aquilanti, Ilario Ferrocino, Vesna Milanović, Cristiana Garofalo, Francesca Clementi, Luca Cocolin, Massimo Mozzon, Roberta Foligni, M.

Bdellovibrio bacteriovorus to control Escherichia coli on meat matrices

Bdellovibrio bacteriovorus is a predator micro-organism towards other Gram-negative bacteria. We tested B. bacteriovorus to control Escherichia coli growth on chicken slices and canned beef. Moreover, we analysed B. bacteriovorus's lytic ability on eight toxigenic or multidrug-resistant E. coli strains. In chicken slices, the predator induced the highest prey reduction (4.3 log) respect to control at 6 h. In canned beef, the predator induced the highest prey reduction (2.1 log) respect to control at 6 h. Moreover, B. bacteriovorus showed lytic ability towards all tested E. coli strains. B. bacteriovorus could control E. coli and other pathogenic and spoilage bacteria in those meat-based foods that have a shelf life <10 days. It could integrate modified atmosphere packaging (MAP) to prolong the shelf life and improve the safety of pre-packed fresh meat, meat preparations and meat products. In future applications on meat-based foods, B. bacteriovorus could also minimise the use of additives

Contribution of vegetables and cured meat to dietary nitrate and nitrite intake in Italian population: Safe level for cured meat and controversial role of vegetables

Nitrate and nitrite content was determined on a total of 900 samples of vegetables and cured meat and the nitrite and nitrate exposure assessment was evaluated for central Italy population based on the food consumption data reported by the national dietary surveys. The highest average content of nitrate was detected in rocket salad (4415 mg/kg) and radish (3817 mg/kg) and for cured meat in “Bresaola” (188 mg/kg) and in Bacon (178 mg/kg). The nitrite content was negligible both in vegetables than in cured meat. The average consumption among population resulted 3.45 g/kg bw/die and 0.62 g/kg bw/die for vegetables and cured meat respectively. The obtained data confirm that nitrate ADI was higher than the limits of 3.7 mg/kg bw/die for infants and was the highest exposure level for people of all ages. Cured meat consumption did not contribute to nitrate ADI exceedance neither as a mean nor as 99th percentile of exposure

Spindle cell oncocytoma of the adenohypophysis in a woman: a case report and review of the literature

<p>Abstract</p> <p>Introduction</p> <p>Spindle cell oncocytoma of the adenohypophysis is a rare tumour recently reported by Roncaroli <it>et al. </it>in 2002. This tumour is considered a grade I tumour by the World Health Organization.</p> <p>Case presentation</p> <p>We describe what is, to the best of our knowledge, the 14th case of its kind in the literature. A 45-year-old African woman presented clinical and radiological findings related to a nonfunctioning pituitary adenoma. The diagnosis was made on the basis of histological and immunohistochemical findings.</p> <p>Conclusion</p> <p>The purpose of this work is to report a rare pituitary tumour and to describe its histological and immunohistochemical features, which were characterized by the expression of thyroid transcription factor 1 antigen by tumour cells. This fact could support the theory of a possible common origin of these tumours in pituicytomas. In fact, thyroid transcription factor 1 is considered to be a specific marker of pituicytes.</p
