After aneurysmal subarachnoid hemorrhage (SAH), patients frequently present with persistent bodily, psychosocial, and cognitive impairments that resemble those of patients with untreated partial or complete pituitary insufficiency. Because of these similarities, the authors hypothesized that aneurysmal SAH may cause pituitary dysfunction. Pituitary function(More)
Glioblastoma multiforme (GBM) is the most frequent and devastating primary brain tumor in adults. The presence of epigenetic lesions, like hypermethylation of known tumor suppressor genes such as MGMT, has been widely described in GBM, but to our knowledge, a genome-wide profile of DNA methylation changes in these lethal tumors is not yet available. In the(More)
OBJECTIVES Presurgical mapping of motor function is a widely used clinical application of functional (f) MRI, employing the blood oxygenation level dependent contrast. The aim of this study was to report on 3 years experience of 194 fMRI studies on the representation of motor function in 103 patients and to describe the problems and artefacts that were(More)
We have tested a treatment protocol for intracerebral hemorrhage (ICH), consisting of stereotactic insertion of a catheter into the clot, hematoma lysis by the injection of a fibrinolytic agent, recombinant tissue-plasminogen activator (rt-PA), and closed system drainage of the liquefied clot. Fourteen patients underwent computed tomographically guided(More)
STUDY DESIGN An analysis of the incidence of spondylodiscitis after lumbar disc surgery in 1642 patients. In 508 patients no prophylactic antibiotics were given. In 1134 patients a collagenous sponge containing gentamicin was placed in the cleared disc space. OBJECTIVES To report the incidence of postoperative spondylodiscitis in cases in which no(More)
OBJECTIVE Frame-based stereotactic puncture and catheter placement followed by fibrinolytic therapy and drainage is one treatment option in the management of spontaneous intracerebral hemorrhage (sICH). This minimally invasive procedure could even be simplified by frameless stereotaxy. The authors present their experiences with frameless stereotactic(More)
OBJECT The goal of this report was to describe the authors' initial experiences with an adjustable gravity-assisted valve (GAV) called the ProGAV in treating childhood hydrocephalus. METHODS The ProGAV was implanted in 53 children (29 boys and 24 girls, median age 7.3 years) with hydrocephalus of various origins. The ProGAV consists of a(More)
In multiple sclerosis, brain-reactive T cells invade the central nervous system (CNS) and induce a self-destructive inflammatory process. T-cell infiltrates are not only found within the parenchyma and the meninges, but also in the cerebrospinal fluid (CSF) that bathes the entire CNS tissue. How the T cells reach the CSF, their functionality, and whether(More)
PURPOSE In patients with newly diagnosed glioblastoma that harbors a nonmethylated O(6)-methylguanine-DNA methyltransferase promotor, standard temozolomide (TMZ) has, at best, limited efficacy. The GLARIUS trial thus explored bevacizumab plus irinotecan (BEV+IRI) as an alternative to TMZ. PATIENTS AND METHODS In this phase II, unblinded trial 182 patients(More)
This study was performed to analyze the effect of intraventricular hemorrhage (IVH) on 14-day mortality, outcome at 6 months, and the occurrence of chronic hydrocephalus in patients with aneurysmal subarachnoid hemorrhage. Clinical grade of subarachnoid hemorrhage and the distribution of extravasated blood were evaluated in 219 patients with ruptured(More)
