Bilateral deep brain stimulation in Parkinson's disease: a multicentre study with 4 years follow-up.

Deep brain stimulation (DBS) is associated with significant improvement of motor complications in patients with severe Parkinson's disease after some 6-12 months of treatment. Long-term results in a large number of patients have been reported only from a single study centre. We report 69 Parkinson's disease patients treated with bilateral DBS of the subthalamic nucleus (STN, n = 49) or globus pallidus internus (GPi, n = 20) included in a multicentre study. Patients were assessed preoperatively and at 1 year and 3-4 years after surgery. The primary outcome measure was the change in the 'off' medication score of the Unified Parkinson's Disease Rating Scale motor part (UPDRS-III) at 3-4 years. Stimulation of the STN or GPi induced a significant improvement (50 and 39%; P < 0.0001) of the 'off' medication UPDRS-III score at 3-4 years with respect to baseline. Stimulation improved cardinal features and activities of daily living (ADL) (P < 0.0001 and P < 0.02 for STN and GPi, respectively) and prolonged the 'on' time spent with good mobility without dyskinesias (P < 0.00001). Daily dosage of levodopa was significantly reduced (35%) in the STN-treated group only (P < 0.001). Comparison of the improvement induced by stimulation at 1 year with 3-4 years showed a significant worsening in the 'on' medication motor states of the UPDRS-III, ADL and gait in both STN and GPi groups, and speech and postural stability in the STN-treated group. Adverse events (AEs) included cognitive decline, speech difficulty, instability, gait disorders and depression. These were more common in patients treated with DBS of the STN. No patient abandoned treatment as a result of these side effects. This experience, which represents the first multicentre study assessing the long-term efficacy of either STN or GPi stimulation, shows a significant and substantial clinically important therapeutic benefit for at least 3-4 years in a large cohort of patients with severe Parkinson's disease.

Towards a protocol in speaker recognition analysis.

On all sides there is an increasing need for a protocol in speaker recognition analysis. This need arises not only in the scientific word, but corresponds also to a requirement of guarantee and protection of all the individuals involved in criminal lawsuits. This study aims neither to resolve the problem of the protocol and of the fundamental steps in a speaker recognition analysis, nor to impose a precise methodology to be followed, but is an attempt to stir the stagnant waters of the debate on expert report phonic analysis. The most important steps in the realisation of a phonic expertise are outlined as a basis and a starting point for a future protocol to which should follow the establishment of a phonic experts list.

Surgery of Parkinson's disease: inclusion criteria and follow-up.

Parkinson's disease (PD) is a progressive disturbances of movement that affects mainly the motor system. Prolonged pharmacological administration may result in insufficient control of symptoms and significant side effects. Deep brain stimulation (DBS), targeted at the STN, is a recent surgical procedure that, according to the symptoms response, allows modification of stimulation parameters; its effects are also reversible. In this paper management of surgical patients is reported. It includes patient selection, inclusion and exclusion criteria, postoperative clinical protocol. The evaluation rating scale such as UPDRS, Dyskinesias Rating Scale and Self-Reporting Questionnaire usually administrated on PD patients are analyzed. Surgical inclusion criteria are (1) idiopathic PD, (2) IV or V Hoehn-Yahr stage, (3) severe motor disability, and (4) no dementia or psychiatric abnormalities. Postoperative clinical protocol is analyzed and parameter of stimulation after surgery and at the follow up are reported. Generally DBS allows an improvement of rigidity and tremor; bradykinesia also improves with high frequency stimulation. Results obtained by continuous stimulation show a mean improvement of UPDRS of about 60% and a significant reduction in the drug intake.
