Major depressive disorder (MDD) is characterized by disturbances of mood and affect, but also by a distinct pattern of psychomotor and cognitive deficits such as motor retardation and impaired executive functioning. An important aspect of executive functioning is performance monitoring, i.e., a continuous checking whether intended action goals have been(More)
INTRODUCTION Action monitoring has been reported to be disturbed in Major Depressive Disorder (MDD). Well-known markers for this action monitoring process are the error negativity/error-related negativity (Ne/ERN) and error positivity (Pe), both event-related potentials (ERP) generated in the anterior cingulate cortex. This study aims to explore the impact(More)
BACKGROUND Docetaxel and cisplatin are among the most active antitumor agents in head and neck cancer, and phase I studies found the combination of the two drugs to be feasible. The EORTC ECSG performed a multicenter phase II study in patients with locally advanced, recurrent or metastatic squamous cell carcinoma of the head and neck to evaluate the(More)
BACKGROUND Psychomotor disturbances have been described repeatedly over many centuries. More recently, Sobin and Sackeim [Sobin, C., Sackeim, H.A., 1997. Psychomotor symptoms of depression. Am. J. Psychiatry. 154, 4-17.] discussed the relevance of psychomotor symptoms in depression in an extensive review. Since their report, new pathophysiological,(More)
BACKGROUND In phase II studies of the EORTC-ECTG, acute hypersensitivity reaction, edema and skin toxicity were important side effects of docetaxel (TaxotereTM). PATIENTS AND METHODS Fifty patients with solid tumors were treated with docetaxel at the University Hospital of Antwerp. Of these, 28% developed an acute hypersensitivity reaction and 20% edema.(More)
Docetaxel, a promising inhibitor of microtubule depolymerization has shown significant anti-cancer activity during phase I and early phase II trials. The recommended dosage for phase II trials is 100 mg/m2 every 3 weeks which provides optimal activity with tolerable adverse effects. Docetaxel has shown high single agent activity including use as first- or(More)
Ifosfamide is an alkylating agent used in the treatment of a variety of solid tumours. Ten to 15% of patients treated with ifosfamide develop an encephalopathy. Methylene blue (MB) may be used in the treatment of this encephalopathy. The purpose of this study was to evaluate the neuroprotective effect of MB in these patients and to review the literature.(More)
PURPOSE To determine the safety profile and activity of the combination of docetaxel, cisplatin and 5-fluorouracil (5-FU) in chemotherapy-naive patients with squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS Patients with locally advanced unresectable SCCHN were treated with docetaxel and cisplatin both as a 1-h infusion on day 1(More)
BACKGROUND Previous work suggests that daily life stress-sensitivity may be an intermediary phenotype associated with both genetic risk for depression and developmental stress exposures. In the current analysis we hypothesized that genetic risk for depression and three environmental exposures over the course of development [prenatal stress, childhood(More)
BACKGROUND Although recent studies focusing on major depressive disorder (MDD) suggest altered social decision-making, studies using the Ultimatum Game (UG) in patients with severe, clinical MDD do not exist. Moreover, all aforementioned studies so far focused on responder behavior and thus fairness considerations; to this date, no one investigated social(More)
