简介：法国市场是个高度竞争的市场，有两家卫星付费电视运营商——CanalSatellite公司和TPS公司。CanalSatellite公司不仅是法国，也是欧洲卫星付费电视领域中最强大的竞争者之一。据统计，CanalSatellite公司的用户增加较快，以2004年统计数据为例（2005年数据未统计出），到2004年6月30日的统计数据显示，用户数已接近290万户．其中在法国的用户增加近25万户；而TPS的状况令人担忧，在同一时期内增加不到8万户，还不到CanalSatellite的1／3。这两家运营商在法国市场上竞争是很激烈的。CanalSatellite公司此后宣布了其新的频道阵容．旨在保持对TPS公司的竞争优势。

简介：AbstractCerebrospinal fluid (CSF) fistulae originating from the fallopian canal of the facial nerve is hypothesized to arise due to atypical patterns of subarachnoid space extension into the geniculate ganglion or more distal regions along the intratemporal course of the facial nerve, but its pathogenesis remains poorly understood. Although a rare etiology of CSF fistulae of the temporal bone, there are significant clinical ramifications due to the risk of recurrent meningitis, difficulty in identifying the anatomic location of the CSF leak, and technical challenges associated with surgical repair. We present three clinical cases of arachnoid cysts within the geniculate fossa with or without CSF fistulization and provide histopathologic correlates of this rare clinical phenomenon from a human temporal bone collection. The pediatric and adult patients presented suggest differential pathophysiologic mechanisms associated with CSF fistulae. Temporal bone histology reveals atypical patterns of subarachnoid space extension in the fallopian canal that may underlie arachnoid cyst formation and overt CSF leak from the geniculate region.
