A spontaneously ruptured primitive neuroectodermal tumor/extraosseous Ewing's sarcoma of the kidney with renal vein tumor thrombus
ABSTRACT Primitive neuroectodermal tumor/extraosseous Ewing's sarcoma (PNET/EES) is a childhood disease rarely seen in adults. It is a soft tissue tumor, which is often observed in the paraspinal region and lower extremity. We report the case of a 32-year-old man who presented with sudden abdominal pain on the right upper quadrant that was radiated to the right flank. During the operation, a spontaneously ruptured right kidney mass was found. The histopathologic and immunohistochemical characteristics of the excised mass were consistent with PNET/EES. This is the first known reported case of spontaneously ruptured PNET/EES of the kidney with renal vein tumor thrombus. The clinical details and the management of this case are described.
Conference Paper: ISDN direct subscription parameter management[Show abstract] [Hide abstract]
ABSTRACT: The authors present an ISDN (integrated services digital network) customer control capability, direct subscription parameter management (DSPM). This capability would enable a user to directly set and later modify values of certain subscription parameters that characterize the services on that access line. This capability would consist of a standard communications protocol on the D-channel and switch based data verification and processing capabilities. Users could use of a range of customer premise equipment (CPE) based applications in conjunction with the network capabilities to perform real-time changes on many of the ISDN subscription parameters. The capability for direct subscription parameter management, in conjunction with the CPE based applications, would provide the ISDN user with the ability to control and make effective use of the extensive flexibility provided by ISDN, while minimizing the need for BOC (Bell Operating Companies) service negotiation interactionsCommunications, 1990.

ABSTRACT: This article reviews the current available information on Ewing's sarcoma of the urogenital tract, focusing on the presentation, diagnosis, and therapeutic management of this uncommon entity. Because of the rapid local growth of these tumors, an immediate decision for treatment initiation is mandatory. The classical presentation depends mainly on the site of involvement of these tumors, involving a palpable mass, hematuria, and pain. No specific diagnostic imaging is available to date, and the only diagnostic method remains histological examination in combination with immunohistochemistry. Treatment involves primary surgical resection of all tumor tissues followed by adjuvant multi-agent chemotherapy. Overall survival is poor, although a 13-year survival has been reached in one case.International Urology and Nephrology 07/2008; 41(1):13-7. DOI:10.1007/s11255-008-9415-y · 1.29 Impact Factor
