Randomized Controlled Trial Comparative StudyGreater improvement in quality of life following unilateral deep brain stimulation surgery in the globus pallidus as compared to the subthalamic nucleus.
While deep brain stimulation (DBS) surgery is a well-accepted treatment for Parkinson disease (PD) that improves overall quality of life (QoL), its effects across different domains of QoL are unclear. The study reported here directly compared the effects of unilateral DBS in subthalamic nucleus (STN) or globus pallidus (GPi) on QoL in 42 non-demented patients with medication-refractory PD. Patients were enrolled in the COMPARE trial, a randomized clinical trial of cognitive and mood effects of STN versus GPi DBS conducted at the University of Florida Movement Disorders Center. ⋯ Within the STN group only, declining category fluency scores correlated with poorer QoL on the communication subscale. Unilateral DBS in both STN and GPi improved QoL overall and in disparate domains 6 months after surgery. Patients receiving GPi DBS reported greater improvements that cannot be explained by differential mood or motor effects; however, verbal fluency changes may have partially contributed to lesser QoL improvements amongst STN patients.

Influence of direct admission to Comprehensive Stroke Centers on the outcome of acute stroke patients treated with intravenous thrombolysis.
Acute stroke patients can be transferred directly to a Comprehensive Stroke Center (CSC), where acute stroke expertise is provided 24 h a day, seven days a week, and thrombolytic treatment is administered; or they may initially receive attention at an unspecialized community hospital with secondary transfer to the CSC. Our aim is to analyze the influence of previous attention at unspecialized community hospitals on the outcome of ischemic stroke patients treated with thrombolysis. We studied 153 consecutive ischemic stroke patients treated with t-PA over a 30-month period. ⋯ Patients who received initial attention at the CSC had a higher frequency of neurologic improvement (59.3% vs. 37.2%; p = 0.014) and a lower rate of symptomatic hemorrhage (4.7% vs. 14%; p = 0.04). Compared to initial attention at an unspecialized hospital, direct admission to the CSC was associated with an odds ratio of 2.48 (95% CI, 1.04-5.88; p = 0.039) for good outcome after adjustment for stroke severity at baseline and other potential confounders. Direct access to a CSC is associated with shorter onset-to-treatment time and better outcome for ischemic stroke patients treated with thrombolysis in comparison with initial attention at an unspecialized hospital with secondary transfer.

Review Historical ArticleHeadaches in antiquity and during the early scientific era.
This paper presents the evolution of ideas on headache symptoms from antiquity through the 19th century. A thorough study of texts, medical books and reports along with a review of the available literature in PubMed was undertaken: observations on headaches date back nearly 4,000 years to the ritual texts of Mesopotamia. ⋯ Overall, observations on headaches span a timeline of nearly 9,000 years. The work of the physicians during the 18th and 19th century, however, set the basis for scientific research.
