Oncocytomas are defined as tumors containing in excess of 50% large mitochondrion-rich cells, irrespective of histogenesis and dignity. Along the central neuraxis, oncocytomas are distinctly uncommon but relevant to the differential diagnosis of neoplasia marked by prominent cytoplasmic granularity. We describe an anaplastic ependymoma (WHO grade III) with(More)
AIMS To evaluate risk factors in lymph node-positive bladder cancer. METHODS AND RESULTS Lymph node-positive bladder cancer patients (n=162), preoperatively staged N0M0, underwent cystectomy and standardized extended lymphadenectomy. Five-year overall survival of the cohort was 33%. In univariate analysis, tumour stage (P<0.006), extracapsular extension(More)
BACKGROUND AND PURPOSE The biological mechanisms predisposing intracranial saccular aneurysms to growth and rupture are not yet fully understood. Mural cell loss is a histological hallmark of ruptured cerebral aneurysms. It remains unclear whether mural cell loss predisposes to aneurysm growth and eventual rupture. METHODS Sodium dodecyl sulfate(More)
AIMS To evaluate the number of lymph nodes and the lymph node tumour burden in different anatomical pelvic regions to better asses the impact of variations in the extent of lymphadenectomy on reported LN parameters and pelvic tumour clearance. METHODS 162 patients with lymph-node-positive urothelial carcinoma of the bladder were treated by cystectomy and(More)
CD10 predicts survival in different cancers. The prognostic significance in bladder cancer still has to be documented. One hundred fifty lymph node-positive bladder cancer patients were treated by cystectomy and standardized pelvic lymphadenectomy in curative intent. CD10 expression was evaluated in tissue microarrays (TMAs) constructed from(More)
INTRODUCTION Pathophysiological disturbances during subarachnoid hemorrhage (SAH) and within the first few days thereafter are responsible for significant brain damage. Early brain injury (EBI) after SAH has become the focus of current research activities. The purpose of the present study was to evaluate whether a novel rabbit SAH model provokes EBI by(More)
During ALL chemotherapy, a 4-year-old patient presented with febrile neutropenia and abdominal pain. Ultrasound examinations were repeatedly normal. Computerized tomography on day 7 demonstrated appendicitis and multiple hepatic foci identified as mucormycosis (Absidia corymbifera). Successful outcome was achieved by aggressive re-surgery, long-term(More)
BACKGROUND Microvascular dysfunction and microthrombi formation are believed to contribute to development of early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (SAH). OBJECTIVE This study aimed to determine (i) extent of microthrombus formation and neuronal apoptosis in the brain parenchyma using a blood shunt SAH model in rabbits; (ii)(More)
