Association of white matter diffusion characteristics and cognitive deficits in temporal lobe epilepsy.

Objective: The purpose of this study was to evaluate the relation between cognitive performance and white matter (WM) integrity in patients with temporal lobe epilepsy (TLE) with mesial temporal sclerosis (MTS).

Methods: We included 26 patients with TLE (10 right, 16 left onset) as well as 24 healthy controls matched for age, gender, and years of education. In addition to quantitative hippocampal volume and transverse relaxation (T2) evaluation, whole-brain WM was analyzed using fractional anisotropy (FA) maps, derived from the diffusion tensor model.

Hippocampal Volumetry as a Biomarker for Dementia in People with Low Education.

Background/aims: To evaluate the relationship between hippocampal volume and cognitive decline in patients with dementia due to probable Alzheimer's disease (AD), amnestic mild cognitive impairment (aMCI) and education, and the possible relationship between cognitive reserve and education in this population.

Methods: From February 2013 to October 2015, 76 patients (25 men, 51 women) were classified according to the NIA-AA diagnostic criteria. We used two 3.

Diagnosis and Treatment Options of Spinal Metastases.

Cancer patients with spinal metastases are a diagnostic and treatment challenge for the clinician. This challenge must be addressed through a multidisciplinary, multimodal, and individualized management. The presence of tumor cells in bone metastases results in homeostatic disruption between bone formation and remodeling.

Percutaneous vertebroplasty in vertebral metastases from breast cancer: interest in terms of pain relief and quality of life.

Percutaneous vertebroplasty (PV) is a therapeutic option in patients with vertebral metastases (VM). However its efficacy in pain relief, improvement in quality of life and safety in patients with VM from breast cancer has not been reported. We present a longitudinal retrospective study of 31 consecutively treated female patients with VM from breast cancer where 88 vertebrae were treated in 44 sessions of PV, in which osteolytic, osteoblastic and mixed lesions were recorded.

Dural metastases as a presentation of a Brenner tumor.

We present a 56-year-old woman who came to our institution with a 6-month history of intracranial hypertension. Imaging studies showed diffuse dural enhancement, multiple lytic bone lesions and a tumor in the left ovary. A meningeal biopsy was performed; however, during this procedure the patient developed profuse dural hemorrhage and middle cerebral artery territory infarction and died a few hours later.

Posterior reversible encephalopathy syndrome as a complication of acute lupus activity.

Objectives: We aimed to describe the clinical and imaging characteristics; associated risk factors and neurological outcome of posterior reversible encephalopathy syndrome (PRES) in patients with systemic lupus erythematosus (SLE).

Methods: From October 2001 to January 2007, we identified patients with SLE and the criteria for PRES in our institution, which is a tertiary-care referral center for patients with SLE; the patients were evaluated at baseline and followed to determine the clinical outcome.

Results: We identified 22 episodes of PRES in 21 patients; 20 (95.

Characterization of the muscle involvement in dynamin 2-related centronuclear myopathy.

Centronuclear myopathy (CNM) is a slowly progressive congenital myopathy characterized by abnormal centrally located nuclei in a large number of muscle fibres. Recently, different missense mutations affecting the middle domain of the dynamin 2 (DNM2) have been shown to cause autosomal dominant CNM. In order to better define the phenotype of DNM2-related CNM, we report here on the clinical and muscle imaging findings of 10 patients harbouring DNM2 mutations.

Percutaneous vertebroplasty for spinal metastases: complications.

Purpose: To retrospectively evaluate complications of percutaneous vertebroplasty (PV) performed with polymethylmethacrylate cement to treat pain in patients with metastases to the spine.

Materials And Methods: This study had institutional review board approval; patient informed consent for the review of records and images was not required. In 2 years, 117 patients (38 men [32.

Unruptured intracranial aneurysms treated by three-dimensional coil embolization: evaluation of the postoperative aneurysm occlusion volume.

Our purpose was to evaluate the postoperative aneurysm occlusion volume and clinical results of treating unruptured intracranial aneurysm using three-dimensional (3D) coils. Over a 2-year period 62 aneurysms (39 with a neck < or =4 mm, 23 with a neck >4 mm) in 62 patients in five participating centres were treated. The procedure consisted, firstly, of framing the aneurysm with one or more spherical 3D coils, and secondly, of filling it with two-dimensional (2D) helical coils.

Brain magnetic resonance imaging findings in patients with mitochondrial cytopathies.

Background: Mitochondrial cytopathies (MCs) are a heterogeneous group of clinical entities, some of which have classic phenotypes. Magnetic resonance imaging (MRI) has been reported to be helpful in the diagnosis of MC.

Objective: To correlate the most common brain MRI findings reported in patients with MC with the clinical findings in patients in different MC subgroups.

[Cardiac involvement in Kearns-Sayre syndrome].

The mitochondrial cytopathies or oxidative-phosphorylation diseases are a diverse group of disorders that result from the structural, biochemical, or genetic derangement of mitochondria. Because mitochondrial dysfunction can affect the most highly energy-dependent organs, cardiac involvement is frequent in these diseases. To identify the clinical features of Kearns-Sayre syndrome, an entity associated with this group of diseases, we evaluated cardiac structure and function in 5 patients with Kearns-Sayre syndrome and followed the clinical course of these patients for 5 years.
