Randomized Controlled Trial Multicenter StudyRopinirole improves depressive symptoms and restless legs syndrome severity in RLS patients: a multicentre, randomized, placebo-controlled study.
Comorbid depressive symptoms in restless legs syndrome (RLS) remain a treatment challenge, as some antidepressants aggravate RLS symptoms. Preliminary data in depressive patients suggest antidepressant properties of ropinirole. The present study investigates the effects of ropinirole immediate release (IR) on depressive symptoms and RLS severity. ⋯ Three out of four subdomains of the Medical Outcomes Study Sleep Scale improved significantly. The findings indicate that mild to moderate depressive symptoms should not be treated before sufficient therapy for RLS. Antidepressant medication can be necessary if depression symptoms still persist even if RLS symptoms are ameliorated.

Central neuropathic pain after cerebral venous thrombosis is not so uncommon: an observational study.
Central neuropathic pain (CNP) after stroke has not been studied in sufficient detail and published studies have only included patients with cerebral artery infarct or hemorrhage. This study evaluates the prevalence and factors associated with CNP after cerebral venous (and sinus) thrombosis (CVT). This observational study included all patients admitted to our stroke unit for CVT between January 2002 and December 2007. ⋯ Initial motor deficit (87 vs. 17%, p < 0.001), initial sensory deficit (62 vs. 20%, p = 0.03), cerebral infarction (75 vs. 23%, p = 0.009), right-sided lesion on initial MRI (62 vs. 17%, p = 0.017), thalamic (37 vs. 0%, p = 0.005) and basal ganglia involvement (25 vs. 0%, p = 0.03) and vein of Galen occlusion (25 vs. 0%) were significantly associated with CNP. Despite several methodological limitations, CNP after CVT seems to be frequent, accounting for one-fifth of all cases of CVT. Some clinical and radiological factors might contribute to the development of CNP.

Case ReportsSMART syndrome: a late reversible complication after radiation therapy for brain tumours.
With intensified treatment leading to longer survival, complications of therapy for brain tumours are more frequently observed. Regarding radiation therapy, progressive and irreversible white matter disease with cognitive decline is most feared. We report on four patients with reversible clinical and radiological features occurring years after radiation for brain tumours, suggestive for the so called SMART syndrome (stroke-like migraine attacks after radiation therapy). ⋯ The pathophysiology of the SMART syndrome is poorly understood but bears similarities with the posterior reversible encephalopathy syndrome (PRES). These four cases underline that the SMART syndrome should be considered in patients formerly treated with radiation therapy for brain tumours, who present with new neurologic deficits. Before the diagnosis of SMART syndrome can be established other causes, such as local tumour recurrence, leptomeningeal disease or ischemic disease should be ruled out.
