Anthracosis, a Distinct Cause of Vocal Fold Paralysis: Case Series.

Vocal fold paralysis (VFP) can happen in various conditions due to mediastinal LADs, however no study has proposed anthracosis as an etiology. Here we discussed the chest CT features of anthracosis related LADs causing VFP. Among 41 cases of pulmonary anthracosis, 10 had VFP that all were presented with hoarseness.

Comparison of endovascular coiling and surgical clipping for the treatment of intracranial aneurysms: A prospective study.

Background: Management of intracranial aneurysms has made debates about the best treatment modality in recent years. The aim of this study was to compare the interventional outcomes between two groups of patients, one treated with endovascular coiling and the other treated with surgical clipping.

Methods: This prospective study included 48 patients with intracranial aneurysms who underwent endovascular coiling (27 patients) or surgical clipping (21 patients) from July 2011 to August 2013.

Mechanical thrombectomy for cerebral venous sinus thrombosis: a comprehensive literature review.

Background: Endovascular treatment of cerebral venous sinus thrombosis (CVST) includes pharmacological and mechanical thrombolysis.

Methods: The authors searched the English literature on CVST from 1990 to 2012 for all case reports or case series of mechanical thrombectomy.

Results: A total of 64 patients were treated in all published studies.

Age-related frontal hyperactivation observed across different working memory tasks: an fMRI study.

Purpose: To evaluate patterns of activation, convergence and divergence of three functional magnetic resonance imaging (fMRI) Working Memory (WM) tasks in two different age groups. We want to understand potential impact of task and subjects' age on WM activations as well as most important areas with regard to WM functions.

Materials And Methods: Thirty-five healthy volunteers completed visual, verbal, and novel auditory WM tasks.

Developing optimized fMRI protocol for clinical use: comparison of different language paradigms.

Purpose: To compare the potential of five functional magnetic resonance imaging (fMRI) language paradigms in activating language areas in Persian-speaking volunteers in order to optimize these tasks for clinically useful protocol.

Materials And Methods: 16 healthy right-handed Persian-speaking volunteers were studied. Each individual performed five tasks during the fMRI scan: word generation (WG), object naming (ON), word reading (WR), word production (WP), and reverse word reading (RWR).

Noninvasive temperature estimation using sonographic digital images.

Objective: The purpose of this study was to develop and evaluate a speckle-tracking method for tissue temperature estimation due to heating fields using digital sonographic images.

Methods: The temperature change estimation method is based on the thermal dependence of the ultrasound speed and the thermal expansion of the medium. Local changes in the speed of sound due to changes in the temperature produce apparent displacement of the scatterers, and the expansion introduces physical displacement.
