CONTEXT Many patients with unresectable pancreatic and peripancreatic cancer require treatment for malignant biliary obstruction. OBJECTIVES To conduct a meta-analysis of the English language literature (1985-2011) comparing immediate biliary stent placement and immediate surgical biliary bypass in patients with unresectable pancreatic and peripancreatic cancer and analyze associated hospital...

This paper investigates the placement of a finite set of web cache proxies in a computer network with a planar graph topology, based on a dynamic programming approach. Three criteria are defined for the web proxy placement: 1) the min-sum strategy with consolidated request forwarding (MS-CRF); 2) the min-sum criterion with immediate request forwarding (MS-IRF); and 3) the minmax with immediate ...

BACKGROUND The healing of xenograft augmentated intra-alveolar gaps following immediate implant placement (IMIP) after tooth extraction is likely to differ in time and density compared to the native bone part that directly contacts the implant. MATERIAL AND METHODS Secondary implant stability (SIS) data recorded 2-3 months following a late implant placement protocol (LIP) (n= 43) and 6-8 mont...

PURPOSE To investigate the modified protocol for immediate occlusal loading of the zygomatic implants and to report the preliminary results of this modified protocol. MATERIALS AND METHODS Four male patients and 1 female patient with edentulous maxillae were consecutively treated with the zygomatic implants under general anesthesia. All 5 patients were examined by computed tomography and inve...

PURPOSE To demonstrate the feasibility of the application of integrated flat detector (FD) CT and fluoroscopic guidance (iGuide) for the placement of external ventricular drains (EVD) within the neuroangiography suite. METHODS A retrospective review of a prospectively maintained endovascular database identified six patients who underwent EVD placement using iGuide. Patient characteristics, op...

background : since the introduction of silicone based medical devices in to clinical practice, several reports appeared in the medical literature regarding their adverse effects. however, there are few reports of immunologic reactions to these implants. case presentation : a case of systemic reaction to a breast implant inserted for immediate breast reconstruction in a breast cancer patient is ...
