With an individually tailored surgical approach, total tumor removal in 78% of the cases was achieved at the initial surgery. Radical surgery appears to increase slightly the surgical morbidity, but at the same time prolongs the recurrence-free interval. Chordomas cannot be regarded as surgically curable tumors given the 5- and 10-year survival rates in patients harboring such lesions.

Anaemia and lymphopenia predict both flares and SLEDAI within the next year of follow-up.

Objective. Despite broad research in neurotrauma and shock, little is known on systemic inflammatory effects of the clinically most relevant combined polytrauma. Experimental investigation in an animal model may provide relevant insight for therapeutic strategies. We describe the effects of a combined injury with respect to lymphocyte population and cytokine activation. Methods. 45 male C57BL/6J mice (mean weight 27 g) were anesthetized with ketamine/xylazine. Animals were subjected to a weight drop closed traumatic brain injury (WD-TBI), a femoral fracture and hemorrhagic shock (FX-SH). Animals were subdivided into WD-TBI, FX-SH and combined trauma (CO-TX) groups. Subjects were sacrificed at 96 h. Blood was analysed for cytokines and by flow cytometry for lymphocyte populations. Results. Mortality was 8%, 13% and 47% for FX-SH, WD-TBI and CO-TX groups (P < 0.05). TNFα (11/13/139 for FX-SH/WD-TBI/CO-TX; P < 0.05), CCL2 (78/96/227; P < 0.05) and IL-6 (16/48/281; P = 0.05) showed significant increases in the CO-TX group. Lymphocyte populations results for FX-SH, WD-TBI and CO-TX were: CD-4 (31/21/22; P = n.s.), CD-8 (7/28/34, P < 0.05), CD-4-CD-8 (11/12/18; P = n.s.), CD-56 (36/7/8; P < 0.05). Conclusion. This study shows that a combination of closed TBI and femur-fracture/ shock results in an increase of the humoral inflammation. More attention to combined injury models in inflammation research is indicated.

Giant cell glioblastoma is a rare variant within the spectrum of glioblastoma multiforme (GBM) tumors. A giant cell glioblastoma may be associated with a better prognosis than the common type of GBM after combined treatment involving tumor resection and radiochemotherapy. A giant cell glioblastoma may occur at various sites in the brain and spinal cord. To the authors' knowledge, this type of tumor has not been previously reported as arising as an exophytic tumor from the medulla oblongata. The authors report on a 40-year-old man who presented with a large tumor located in the caudal fourth ventricle. The tumor was removed completely and the patient underwent percutaneous radiotherapy with 60 Gy and concomitant chemotherapy with temozolomide. Histopathological examination of the tumor revealed the typical features of a giant cell glioblastoma. At the 2-year follow-up the patient was doing well and showed no signs of tumor recurrence. It is important to identify variants of GBM because they may predict favorable long-term outcome, even when they arise from the caudal brainstem.

While bone invasion and hyperostosis are frequent phenomena in meningiomas, primary intra-osseous meningiomas are rare. With only 15 reported cases, the osteolytic form of primary intra-osseous meningiomas is most uncommon. Its occurrence in the skull base is an extra-ordinary exception. We have reviewed and categorized the pertinent literature on intra-osseus meningiomas with special emphasis on osteolytic tumours and discuss their clinical implications on the basis of a new case located in the petrous bone without contact with the meninges. It is concluded that due to their different clinical, radiological and pathological features, hyperostotic and osteolytic variants of intra-osseus meningiomas should be distinguished from tumours with soft tissue components and from en-plaque lesions.

Idiopathic normal pressure hydrocephalus patients may benefit from shunting over the long term when rigorous selection criteria are applied. Shunt-related mortality is negligible. The main cause of death is vascular comorbidity.

The proGAV is a safe and reliable device.
