Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Duodenal levodopa infusion monotherapy vs oral polypharmacy in advanced Parkinson disease.
To compare daytime intraduodenal levodopa/carbidopa infusion as monotherapy with individually optimized conventional combination therapies in patients with advanced Parkinson disease (PD) for motor fluctuations and quality of life (QoL). ⋯ Continuous intraduodenal infusion of the levodopa/carbidopa enteral gel as monotherapy is safe and clinically superior to a number of individually optimized combinations of conventional oral and subcutaneous medications in patients with motor fluctuations. Intraduodenal infusion of levodopa offers an important alternative in treating patients with advanced Parkinson disease.

Intracranial arterial dolichoectasia is associated with enlarged descending thoracic aorta.
Intracranial arterial dolichoectasia (IADE) is defined as an increase in length and diameter of the intracranial arteries and is present in 12% of stroke patients. The pathophysiology is unknown; some data suggest that IADE is not merely a complication of atherosclerosis, but a distinct arteriopathy characterized by loss of elastic tissue in the media. ⋯ Patients with intracranial arterial dolichoectasia (IADE) have larger descending thoracic aorta diameters than non-IADE patients, suggesting that the underlying process causing IADE also affects the descending thoracic aorta.

Pregabalin relieves symptoms of painful diabetic neuropathy: a randomized controlled trial.
Pregabalin, an alpha2-delta ligand with analgesic, anxiolytic, and anticonvulsant activity, has been evaluated for treatment of neuropathic pain. The authors assessed the efficacy and tolerability of pregabalin (75, 300, 600 mg/day) vs placebo in patients with diabetic peripheral neuropathy (DPN). ⋯ In patients with diabetic peripheral neuropathy, pregabalin demonstrated early and sustained improvement in pain and a beneficial effect on sleep, which were confirmed by positive patient global impression. Pregabalin was well tolerated at all doses.

Repeated dosing of botulinum toxin type A for upper limb spasticity following stroke.
The authors evaluated the long-term efficacy and safety of botulinum toxin type A (BTX-A) in poststroke spasticity patients who completed a 12-week placebo-controlled study and received multiple open-label treatments with 200 to 240 U BTX-A for 42 weeks. Significant and sustained improvements were observed for Disability Assessment and Ashworth scores. Adverse events were generally mild. This extension of a double-blind study demonstrates that repeated treatments of BTX-A significantly improve function and tone in spasticity.

The prevalence of pain in multiple sclerosis: a multicenter cross-sectional study.
In a multicenter cross-sectional study, the authors assessed pain in patients with multiple sclerosis (MS) using a symptom-oriented approach. Out of 2,077 questionnaires, we used 1,672 for data analysis. ⋯ Comparison between different groups showed significant differences for age, Expanded Disability Status Scale, disease duration, and disease course, but not for sex. This study underlines the relevance of pain in the clinical history of MS.
