Rôle du pharmacien d'officine dans la prévention et la prise en charge d'une maladie émergente (la borréliose de Lyme)
La maladie de Lyme ou borréliose de Lyme est une affection émergente en France et au sein de l hémisphère nord, elle est transmise par une tique vectrice du genre Ixodes ricinus porteuse de bactéries spirochètes, Borrelia burgdorferi. Elle se caractérise par un érythème migrant lors de la phase primaire et peut évoluer vers des stades plus tardifs avec de multiples manifestations : cutanées, rhumatologiques, neurologiques et cardiaques. Le diagnostic est parfois difficile et repose sur des arguments anamnestiques cliniques et biologiques. Le traitement repose sur une antibiothérapie et est d autant plus efficace qu il est débuté le plus précocement possible. En l absence de vaccin, la prévention reste fondamentale pour se protéger contre les morsures de tiques et il est également essentiel d extraire la tique au plus vite afin d éviter une éventuelle transmission de la maladie.DIJON-BU Médecine Pharmacie (212312103) / SudocSudocFranceF
Inflammatory Stroma of Lymphoepithelioma-like Carcinoma of the Cervix: Immunohistochemical Study of 3 Cases and Review of the Literature
The aim of this study was to characterize the inflammatory infiltrate of the lymphoepithelioma-like carcinoma, a variant of squamous cell carcinoma clinically associated with a good prognosis. Immunohistochemistry was used to characterize 3 cases of lymphoepithelioma-like carcinoma in the uterine cervix, diagnosed over a period of 3 yr. The patients were between 30 and 50 yr old. Their cervical smears had shown atypical squamous cells of unknown significance or high-grade squamous intraepithelial lesions, and the initial cervical biopsy showed high-grade cervical intraepithelial neoplasia (CIN3) or squamous cell carcinoma. All patients underwent a Wertheim operation, 2 of which were preceded by a cervicectomy. Microscopically, all tumors were characterized by poorly defined sheets of undifferentiated squamous cells with a syncytial pattern and a dense background of infiltrating lymphocytes. Immunohistochemical analysis revealed that the lymphocytes were predominantly CD3 + and CD8 + T cells. The tumor lobules contained isolated CD8 + T cells, whereas CD4 + T cells and CD20 + B cells surrounded the tumor lobules. CD56 + NK cells and CD79 + B cells were scattered in the tumor tissue. An in situ hybridization staining for Epstein-Barr encoding region was negative but all cases were immunohistochemically positive for P16. Follow-up varied between 2 mo and 2.7 yr. All 3 patients were disease free. Lymphoepithelioma-like carcinoma of the uterine cervix is a variant of squamous cell carcinoma, known for its better prognosis. The good prognosis of this tumor is potentially explained by the high levels of infiltrating CD8 + T cells.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Characterization of human breast cancer tissues by infrared imaging.
Fourier Transform InfraRed (FTIR) spectroscopy coupled to microscopy (IR imaging) has shown unique advantages in detecting morphological and molecular pathologic alterations in biological tissues. The aim of this study was to evaluate the potential of IR imaging as a diagnostic tool to identify characteristics of breast epithelial cells and the stroma. In this study a total of 19 breast tissue samples were obtained from 13 patients. For 6 of the patients, we also obtained Non-Adjacent Non-Tumor tissue samples. Infrared images were recorded on the main cell/tissue types identified in all breast tissue samples. Unsupervised Principal Component Analyses and supervised Partial Least Square Discriminant Analyses (PLS-DA) were used to discriminate spectra. Leave-one-out cross-validation was used to evaluate the performance of PLS-DA models. Our results show that IR imaging coupled with PLS-DA can efficiently identify the main cell types present in FFPE breast tissue sections, i.e. epithelial cells, lymphocytes, connective tissue, vascular tissue and erythrocytes. A second PLS-DA model could distinguish normal and tumor breast epithelial cells in the breast tissue sections. A patient-specific model reached particularly high sensitivity, specificity and MCC rates. Finally, we showed that the stroma located close or at distance from the tumor exhibits distinct spectral characteristics. In conclusion FTIR imaging combined with computational algorithms could be an accurate, rapid and objective tool to identify/quantify breast epithelial cells and differentiate tumor from normal breast tissue as well as normal from tumor-associated stroma, paving the way to the establishment of a potential complementary tool to ensure safe tumor margins.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Starlikeness of Libera transformation (II) (Applications of Complex Function Theory to Differential Equations)
The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 25 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017.
