BACKGROUND Given that memantine is thought to decrease N-methyl-D-aspartic-acid-related (NMDA) glutamatergic hyperactivity and improve locomotion in rats, we sought to assess the drug's impact on axial symptoms in advanced Parkinson's disease (PD). METHODS We performed a 90-day, randomised, double-blind, study with two parallel arms: 20 mg/day memantine(More)
BACKGROUND Despite optimum medical management, many patients with Parkinson's disease are incapacitated by gait disorders including freezing of gait. We aimed to assess whether methylphenidate--through its combined action on dopamine and noradrenaline reuptake--would improve gait disorders and freezing of gate in patients with advanced Parkinson's disease(More)
OBJECTIVE To evaluate the role of ¹⁸F-fluorodeoxyglucose-positron emission tomography (FDG-PET) in the assessment of tumor response after the completion of neoadjuvant chemoradiation (CRT) in patients with locally advanced resectable esophageal cancer. BACKGROUND After primary CRT, a noninvasive evaluation of the tumor response could help in the treatment(More)
In this focus, we review, in the light of the recent literature, the modalities and indications of surgical cerebral revascularization for Moyamoya (MM) disease or syndrome. We also report our experience in the surgical management of adult MM. In symptomatic forms, with presence of severe disturbances of perfusion or cerebrovascular reactivity on multimodal(More)
INTRODUCTION [¹⁸F]-Fluorodeoxyglucose PET has become an essential technique in oncology. Accurate segmentation is important for treatment planning. With the increasing number of available methods, it will be useful to establish a reliable evaluation tool. METHOD Five methods for [F]-fluorodeoxyglucose PET image segmentation (MIP-based, Fuzzy C-means,(More)
PURPOSE OF REVIEW To review the current status of advanced imaging techniques in identification of organ-confined prostate cancer with a focus on their impact on patient management. RECENT FINDINGS Transrectal ultrasound suffers from poor accuracy despite significant technical improvements. Generally used to distinguish cancers with extraprostatic spread,(More)
BACKGROUND Combination of bevacizumab and weekly paclitaxel showed synergitic effects, anti-tumor efficacy and a good toxicity profile for patients with breast cancer but has never been evaluated in non small cell lung cancer (NSCLC). We retrospectively reviewed safety and efficacy of this regimen in metastatic non-squamous NSCLC as fourth-line therapy or(More)
AIMS Previous studies have demonstrated that the radionuclide right ventricular (RV) ejection fraction (RVEF), tricuspid annular plane systolic excursion (TAPSE), and tissue Doppler peak systolic tricuspid annular velocity (STr) were independent predictors of cardiac survival in stable patients with left ventricular systolic dysfunction (LVSD). No study has(More)
After more than 50 years of treating Parkinson's disease with l-DOPA, there are still no guidelines on setting the optimal dose for a given patient. The dopamine transporter type 1, now known as solute carrier family 6 (neurotransmitter transporter), member 3 (SLC6A3) is the most powerful determinant of dopamine neurotransmission and might therefore(More)
