OBJECTIVES A series of three recurrent central neurocytomas treated by gamma knife radiosurgery (GKRS), which were initially totally resected, are described. Up to now, no reports exist on this treatment modality for this rare tumour entity. METHODS Three male patients, aged between 20 and 25 years, presented with large intraventricular tumours. Total(More)
Background Rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a recently characterized rare tumor entity. Despite benign histological features and a reported favorable postoperative course, there is still limited clinical experience with this tumor. Methods Retrospective analysis of the clinical, radiological, and surgical data in four(More)
OBJECTIVE To investigate the diagnostic accuracy and current role of intraoperative cytologic smears of central nervous system tumors. STUDY DESIGN Retrospective analysis of 4,172 patients operated on during 1985-1999, with 3,541 intraoperative smears performed during open procedures and 631 during stereotactic biopsies. RESULTS Complete correlation(More)
OBJECTIVE To analyze the effect of prone position on cerebral perfusion pressure and brain tissue oxygen partial pressure in subarachnoid hemorrhage patients with acute respiratory distress syndrome (ARDS). DESIGN Clinical study with retrospective data analysis. SETTING Neurosurgical intensive care unit of a primary level university hospital. PATIENTS(More)
Introduction: A retrospective analysis of 42 preterm infants with intraventricular hemorrhage was performed in order to evaluate shunt-related problems in neonates with posthemorrhagic hydrocephalus. Patients and methods: Within the last 15 years, 76 infants with intraventricular hemorrhage were treated primarily by external ventricular drainage, and 42(More)
BACKGROUND Patients with insulin dependent diabetes require frequent advice if their metabolic control is not optimal. This study focuses on the fiscal and administrative aspects of telemanagement, which was used to establish a supervised autonomy of patients on intensified insulin therapy. METHODS A prospective, randomised trial with 43 patients on(More)
OBJECTIVE To analyze the influence of extracerebral organ system dysfunction after aneurysmal subarachnoid hemorrhage (SAH) on mortality and neurologic outcome. DESIGN Observational study with retrospective data extraction. SETTING Neurosurgical intensive care unit (NICU) at a primary level university hospital, supervised and staffed by both members of(More)
OBJECT The concept of selective amygdalohippocampectomy is based on pathophysiological insights into the epileptogenicity of the hippocampal region and the definition of the clinical syndrome of mesial temporal lobe epilepsy (TLE). High-resolution magnetic resonance (MR) imaging allows correlation of the site of histologically conspicuous tissue with(More)
The pressure-adjustable valve system Codman Medos allows valve pressure adjustment in 18 steps between 30 and 200 mm H2O. A series of 90 patients, 15 children and 75 adults, who were shunted with this new programmable valve, is reported. Indication for shunt insertion were various types of hydrocephalus in 79 cases, malfunction of a medium pressure membrane(More)
Introduction Erlotinib and Gefitinib (EGFRi) are small molecules specifically inhibiting epidermal growth factor receptor (EGFR). We present here data of an exploratory study evaluating EGFRi monotherapy in patients with recurrent or progressive malignant glioma. Patients 21 patients with recurrent or progressive malignant glioma were included in this(More)
