Background: Safinamide is a recent multimodal antiparkinsonian drug that inhibits monoamine oxidase B and modulates the glutamatergic system with positive effects on motor and nonmotor symptoms of Parkinson's disease (PD). This post-hoc analysis of the European SYNAPSES study provides first-time data on the use of safinamide in routine clinical practice in Belgium., Objective: To describe the efficacy and safety of safinamide in Belgian PD patients in real-life conditions., Methods: Post-hoc analysis of the Belgian cohort from the European SYNAPSES trial, which was an observational, multicenter, retrospective-prospective cohort study. Patients were followed up to 12 months. Analyses were performed in the overall population and according to different criteria such as the age limit (> 75 years), presence or absence of relevant comorbidities, presence or absence of psychiatric conditions such as depression and anxiety, patients on levodopa monotherapy or levodopa in combination with other treatments, patients on rasagiline before inclusion or not., Results: Of the 172 patients included, 29.2% were > 75 years, 58.9% had relevant comorbidities and 32.7% had psychiatric conditions. Almost all the patients reported motor (98.8%) or non-motor (86.3%) symptoms. During the study, 36.3% of patients reported drug-related reactions. The adverse drug reactions were those already described in the patients' information leaflet. The majority were mild or moderate and completely resolved and no differences were detected between the subgroups of patients. Almost 35% of the patients demonstrated a clinically significant improvement in the UPDRS and 50% of the patients with wearing-off at baseline, did not report wearing-off anymore after one year of treatment. Patients under levodopa monotherapy compared to patients receiving levodopa combined with other antiparkinsonian treatments benefit more from safinamide treatment. Patients switched from rasagiline to safinamide seemed also to benefit more from safinamide treatment., Conclusion: The study confirms the excellent safety and efficacy profile of safinamide, particularly in more vulnerable groups of patients such as the elderly and patients with significant comorbidities or psychiatric conditions such as depression or anxiety., (© 2022.

Background: Deep brain stimulation (DBS) of the sub-thalamic nucleus (STN) is a recognised treatment for advanced Parkinson's disease (PD). We present our results of 10 consecutive patients implanted under general anaesthesia (GA) using intraoperative robotic three-dimensional (3D) fluoroscopy (Artis Zeego; Siemens, Erlangen, Germany)., Method: Ten patients (nine men, one woman) with a mean age of 57.6 (range, 41-67) years underwent surgery between October 2013 and January 2015. The mean duration of PD was 9.2 [1-10] year. The procedure was performed under GA: placement of the stereotactic frame, implantation of the electrodes (Lead 3389; Medtronic, Minnesota, MN, USA) and 3D intraoperative fluoroscopic control (Artis Zeego) with image fusion with the preoperative MRI scans. All patients were evaluated preoperatively and 6 months postoperatively., Results: The mean operative time was 240.1 (185-325) min. The mean Unified Parkinson's Disease Rating Scale (UPDRS) II OFF medication decreased from 23.9 preoperatively to 15.7 postoperatively. The mean OFF medication UPDRS III decreased from 41 to 11.6 and the UPDRS IV decreased from 10.6 to 7. The mean preoperative and postoperative L-Dopa doses were 1,178.5 and 696.5 mg, respectively. Two complications were recorded: one episode of transient confusion (24 h) and one internal pulse generator (IPG) infection., Conclusions: With improvement in preoperative magnetic resonance imaging (MRI) and the ability to control the position of the leads intraoperatively using Artis Zeego, we now perform this procedure under GA. Our results are comparable to others reported. The significant decrease in the duration of surgery could be associated with a reduced rate of complications (infection, loss of patient collaboration). However, this observation needs to be confirmed.

Objective: A 'case scenario' study on clinical decisions in progressing Parkinson's disease (PD) was developed to complement scientific evidence with the collective judgment of a panel of experts., Methods: The opinions of 9 experts in movement disorders on the appropriateness of 9 common pharmacological treatments for 33 hypothetical patient profiles were compared to those of 14 general neurologists. Before rating the case scenarios, all participants received a document integrating European and US guidelines for the treatment of patients with advanced PD. Case scenarios showing disagreement or with inconsistencies in appropriateness ratings were discussed at a feedback meeting. A tool for interactive discussion on the clinical case scenarios included was developed based on the outcome of the study., Results: Current guidelines are often insufficient to adequately guide the management of patients with progressing PD. The case scenario study did not reveal major differences in opinions between experts in movement disorders and general neurologists about the appropriateness of certain drug choices for specific case scenarios. However in about 1 out of 5 treatment decisions where experts stated appropriateness or inappropriateness, the general neurologists panel had no or dispersed opinions., Conclusions: This study reveals more uncertainty about treatment of advanced PD in general neurologists compared with experts in movement disorders and underlines the need for additional support for guiding treatment decisions in clinical practice.
