Novel fabrication technique for high-resolution spherical crystal analyzers using a microporous aluminium base.

Modern inelastic X-ray spectrometers employ curved, bent and diced analyzers to capture sufficiently large solid angles of radially emitted scattered radiation emanating from the sample. Fabricating these intricate analyzers, especially when a high energy resolution of a few millielectronvolts is required, is very time-consuming, expensive and often a hit-or-miss affair. A novel fabrication technique is introduced, utilizing a concave-spherical, microporous aluminium base to hold an assembly of a thin glass substrate with a diced crystal wafer bonded to it.

Parkinson's Disease Symptoms Associated with Developing On-State Axial Symptoms Early after Subthalamic Deep Brain Stimulation.

Background: The relationship between axial symptoms in Parkinson’s disease (PD) and subthalamic deep brain stimulation (STN-DBS) is still unclear. Purpose: We searched for particular clinical characteristics before STN-DBS linked to on-state axial problems after surgery. Methods: We retrospectively analyzed baseline motor, emotional and cognitive features from PD patients with early axial symptoms (within 4 years after STN-DBS) and late axial symptoms (after 4 years).

Continuous subcutaneous apomorphine in advanced Parkinson's disease patients treated with deep brain stimulation.

Introduction: Deep brain stimulation (DBS) is an effective therapy for patients with advanced Parkinson's disease (PD). However, sometimes, it is not sufficient to adequately control motor symptoms. We describe our experience with continuous subcutaneous apomorphine infusion (APO) in patients with DBS.

Delayed complications of deep brain stimulation: 16-year experience in 249 patients.

Background: Over the years, most of the deep brain stimulation (DBS) complications described have been mainly related to the surgery itself or the stimulation. Only a few authors have dealt with chronic complications or complications due to implanted material.

Methods: We retrospectively analyzed complications beyond the 1st month after surgery in 249 patients undergoing DBS at our site for 16 years, with 321 interventions overall.

[Quadrigeminal cistern and calcarine fissure lipoma: case report and review of the literature].

We report the case of a multiple intracranial lipoma in a 47 year-old patient presenting with headache dizziness and quadrantanopsia. MR imaging revealed the presence of 2 lipomas, one located within the quadrigeminal cistern and the other in the calcarine fissure. To our knowledge, this combination of this rare lesion has not been yet described.
