Tumor related contralateral motor deficits complicate preoperative functional magnetic resonance imaging (fMRI). In plegic patients the localization of the sensorimotor cortex is often impossible. In this context we developed a clinical fMRI protocol dedicated to patients with motor deficits using the unaffected ipsilateral hand. Based on the hypothesis(More)
The clinical application of functional magnetic resonance imaging (fMRI) requires time-saving protocols insensitive to artifacts that provide robust localization and important information on brain function. A fully automated, pneumatically driven tactile stimulation is presented, that reproducibly localizes postcentral lip, finger and toe representations in(More)
Radiosurgery (RS) is a noninvasive, ambulatory special neurosurgical procedure for the treatment of vestibular schwannoma (VS). We treated 123 patients with unilateral schwannomas between 1994 and 2000 at the gamma knife (GK) center in Munich using a primary stereotactic procedure. These patients were followed up until June 2004 in respect to audiological,(More)
On the basis of well documented biochemical and pharmacological data about the influence of drug mediated enzyme induction on the biotransformation of natural and synthetic sex steroids, practical consequences for hormonal steroid contraception are described and discussed. Clinical reports dealing with this problem are still sparse. The clinical symptoms of(More)
Whereas some arguments can be advanced suggesting that the life expectancy in east Germany should have declined directly after the fall of the Berlin Wall in 1989, other arguments suggest an increase. The aim of this study was to identify the actual developments and to explain the findings. Census data and mortality statistics from East and West Germany(More)
Caffeine is mainly metabolized by 3-methylcholanthreneinducible cytochrome P-450, whereas metamizol (Analgin) is probably mainly metabolized by the phenobarbital inducible cytochrome P-450 family. Therefore the elimination of caffeine from serum and the elimination of the main metabolites of metamizol in urine reflect the activity of these two cytochrome(More)
