Case ReportsDirect relief of levodopa-induced dyskinesia by stimulation in the area above the subthalamic nucleus in a patient with Parkinson's disease--case report.
A 71-year-old woman with a 25-year history of levodopa (LD)-responsive Parkinson's disease (PD) developed on-off motor fluctuation and severe peak dose dyskinesia. She underwent deep brain stimulation of the subthalamic nucleus (STN-DBS). ⋯ LD-induced dyskinesia can also be controlled via reduction of LD dosage as an indirect effect of STN-DBS. The present case provides evidence of the direct antidyskinetic effect of STN-DBS, and suggests that LD-induced dyskinesia can be inhibited by stimulation in the area above the STN.

Preventive effect of aggressive blood pressure lowering on hematoma enlargement in patients with ultra-acute intracerebral hemorrhage.
The preventive effect of aggressive blood pressure lowering on hematoma enlargement was investigated in patients with ultra-acute spontaneous intracerebral hemorrhage (ICH). Retrospective review of 248 patients (145 males, 103 females) with spontaneous ICH treated in our hospital between 2005 and 2008 identified patients with ultra-acute ICH who were directly taken to our institute by ambulance within 3 hours after onset. Patients who could not be assessed twice by computed tomography (CT) within 24 hours after arrival were excluded. ⋯ The time course of SBP change was not significantly different in patients with and without hematoma enlargement. The incidence of hematoma enlargement in patients with ultra-acute ICH in this study was 15.0%, which was lower than that in other series in which blood pressure was not reduced aggressively. This finding suggests that aggressive SBP lowering to below 140 mmHg has a preventive effect on hematoma enlargement in patients with ultra-acute ICH.

Case ReportsMotor cortex stimulation for intractable neuropathic facial pain related to multiple sclerosis.
A 33-year-old man presented with ongoing severe right facial pain and sensory disturbances caused by multiple sclerosis (MS). Neuroimaging demonstrated demyelinating lesions in the right dorsal pons and medulla oblongata. ⋯ The patient underwent motor cortex stimulation (MCS), resulting in >60% pain relief, reduction in the required doses of pain medications, and discontinuation of ketamine administration. MCS is effective for MS-related neuropathic facial pain.

Case ReportsSplitting of the oculomotor nerve by the posterior communicating artery--case report.
A 62-year-old woman presented with subarachnoid hemorrhage manifesting as sudden onset of headache, but without visual symptoms or extraocular movement disturbances. Computed tomography angiography showed a 7-mm size aneurysm originating from the internal carotid-posterior communicating artery (PcomA). After the neck of the aneurysm was clipped, the PcomA was confirmed to have split the oculomotor nerve. Splitting of the oculomotor nerve by the PcomA was probably caused by arterial blood pulsation in the tortuous PcomA.
