Diagnostic accuracy of multiparametric magnetic resonance imaging in detecting extracapsular extension in intermediate and high - risk prostate cancer

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objectives: To evaluate the diagnostic performance of preoperative multiparametric magnetic resonance imaging (mp-MRI) as a predictor of extracapsular extension (ECE) and unfavorable Gleason score (GS) in patients with intermediate and high-risk prostate cancer (PCa). Materials and Methods: Pa...

Extradural lumbar nerve root cavernous hemangioma: case report and successful surgical resection

Rev. bras. neurol; 54 (3), 2018
Extradural lumbar spinal canal cavernous hemangiomas (or cavernomas) are rare lesions that can induce intense back pain and neurological deficit. We present a case report of a patient with a pure radicular lombar extradural cavernoma resembling a benign neurological tumor in imaging exams and a successfu...

Twenty-five years since the identification of the first SCA gene: history, clinical features and perspectives for SCA1

Arq. neuropsiquiatr; 76 (8), 2018
ABSTRACT Spinocerebellar ataxias (SCA) are a clinically and genetically heterogeneous group of monogenic diseases that share ataxia and autosomal dominant inheritance as the core features. An important proportion of SCAs are caused by CAG trinucleotide repeat expansions in the coding region of different ...

Frecuencia y determinantes de epilepsia luego de un primer ictus isquémico arterial en una cohorte de niños

Existen pocos estudios evaluando los factores de riesgo para el desarrollo de epilepsia posterior a un ictus isquémico arterial (IIA) en la infancia. Objetivo: Evaluar los predictores clínicos y radiológicos para epilepsia post-ictus (EPI) en una cohorte de niños chilenos con un primer IIA. Metodolog...

Support vector machine-based classification of neuroimages in Alzheimer's disease: direct comparison of FDG-PET, rCBF-SPECT and MRI data acquired from the same individuals

Objective: To conduct the first support vector machine (SVM)-based study comparing the diagnostic accuracy of T1-weighted magnetic resonance imaging (T1-MRI), F-fluorodeoxyglucose-positron emission tomography (FDG-PET) and regional cerebral blood flow single-photon emission computed tomography (rCBF-SPEC...

Accuracy of Magnetic Resonance Arthrography in Detecting Rotator Cuff Tears

West Indian med. j; 67 (2), 2018
ABSTRACT Objective: Shoulder pain, a common cause of productivity loss and health-related expense, is commonly due to rotator cuff tears. Magnetic resonance (MR) imaging with intra-articular gadolinium, MR arthrography, is accepted internationally as an excellent modality for evaluating the rotator cuff...

Internal carotid artery aneurysm mimicking normal-tension glaucoma

Arq. bras. oftalmol; 81 (2), 2018
ABSTRACT Differentiating glaucomatous from nonglaucomatous optic disc cupping remains challenging. We present a case of a 48-year-old woman with an internal carotid aneurysm of approximately 3.5 mm × 6.5 mm that mimicked normal-tension glaucoma. The patient had a 2-year history of low vision acuity in h...

Practical Implications of Myocardial Viability Studies

Arq. bras. cardiol; 110 (3), 2018
Abstract Many non-invasive methods, such as imaging tests, have been developed aiming to add a contribution to existing studies in estimating patients' prognosis after myocardial injury. This prognosis is proportional to myocardial viability, which is evaluated in coronary artery disease and left ventric...

Migraine improvement correlates with posterior cingulate cortical thickness reduction

Arq. neuropsiquiatr; 76 (3), 2018
ABSTRACT Objective The main goal of this study was to correlate migraine improvement, after prophylactic therapy, with cortical thickness changes. Methods Cortical thickness maps were obtained with magnetic resonance imaging (MRI) from 19 patients with migraine before (first scan) and after (second sca...
