MRI characterization of rat brain aging at structural and functional level: Clues for translational applications.

Magnetic resonance imaging (MRI) paradigms, using non-invasive approaches, can provide relevant findings about brain aging. The attention has been primarily focused on neurodegenerative diseases, while little or nothing has been done to differentiate physiology from pathology. The present study aimed to test diffusion tensor imaging (DTI) and functional MRI (fMRI) metrics to analyze physiological age-related changes in rats at myelin structure and activation level; findings were validated by ex vivo histology.

Correction to: The Italian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR).

The family name of author Francesco La Torre was incorrect in the published article. The correct family name should read as La Torre F.

The Italian version of the Juvenile Arthritis Multidimensional Assessment Report (JAMAR).

The Juvenile Arthritis Multidimensional Assessment Report (JAMAR) is a new parent/patient reported outcome measure that enables a thorough assessment of the disease status in children with juvenile idiopathic arthritis (JIA). We report the results of the cross-cultural adaptation and validation of the parent and patient versions of the JAMAR in the Italian language.The reading comprehension of the questionnaire was tested in 10 JIA parents and patients.

ADA2 deficiency (DADA2) as an unrecognised cause of early onset polyarteritis nodosa and stroke: a multicentre national study.

Objectives: To analyse the prevalence of mutations in patients diagnosed with early onset livedo reticularis and/or haemorrhagic/ischaemic strokes in the context of inflammation or polyarteritis nodosa (PAN). Forty-eight patients from 43 families were included in the study.

Methods: Direct sequencing of was performed by Sanger analysis.

Disease status, reasons for discontinuation and adverse events in 1038 Italian children with juvenile idiopathic arthritis treated with etanercept.

Background: Data from routine clinical practice are needed to further define the efficacy and safety of biologic medications in children with juvenile idiopathic arthritis (JIA). The aim of this analysis was to investigate the disease status, reasons for discontinuation and adverse events in Italian JIA patients treated with etanercept (ETN).

Methods: In 2013, all centers of the Italian Pediatric Rheumatology Study Group were asked to make a census of patients given ETN after January 2000.

Thalassemia major between liver and heart: Where we are now.

The aim of the study was to assess the current state in terms of liver and heart iron overload as well as of liver and heart related morbidity and mortality in a large cohort of thalassemia patients. Myocardial iron loading was present in 28.9% patients, which was severe in 3.

Asparagine in plums detected by CEST-MRI.

Magnetic resonance imaging (MRI) relies on the topological distribution of the intense water NMR signal and may be used to report about changes in the internal structures of fruits associated to ripening, storing, pathogen infection. Herein the use of CEST-MRI (chemical exchange saturation transfer) is introduced to show that in addition to structural information, insights into the presence in the fruits of specific chemicals may be gained. Asparagine is present in plums at relatively high concentration (≈10-20mM) and owns two amide protons (at 2.

Er:YAG Laser and Fractured Incisor Restorations: An In Vitro Study.

Introduction. The aim of this study was to analyse the effects of an Er:YAG laser on enamel and dentine in cases of dental restorations involving fractured teeth, utilizing the dental fragment. Materials and Methods.

A case of bullous pemphigoid in infancy treated with local corticosteroids.

Bullous pemphigoid (BP) is an immune-mediated subepidermal vesiculobullous eruption, whose true incidence is unknown, but it is considered extremely rare in children, with a usually indolent course and rare relapses. Diagnosis is often belated, because of the invasive assessment with biopsy for typical immune-pathologic findings to differentiate it from Dermatitis Herpetiformis and Linear IgA bullous dermatosis (LABD), more common in children. A 4-year-old girl presented with one year history of erythematous-edematous and erythematous-bullous eruptions on the genitalia, periocular regions, dorsal and palmo-plantar surfaces.

Methotrexate treatment in juvenile localized scleroderma: a randomized, double-blind, placebo-controlled trial.

Objective: Juvenile localized scleroderma is a chronic progressive fibrotic disorder of the skin that causes permanent disability and aesthetic damage. This study was undertaken to assess the safety and efficacy of methotrexate (MTX) in the treatment of juvenile localized scleroderma.

Methods: In this double-blind study, patients with active juvenile localized scleroderma were randomized (2:1) to receive oral MTX (15 mg/m², maximum 20 mg) or placebo once weekly, for 12 months or until treatment failure.

Molecular analysis of glycogen storage disease type Ib in Sardinian population: evidence for a founder effect.

We describe epidemiological, genetic, and clinical data of the 1124-2del mutation in the G6PT gene, detected in homozygosity in three glycogen storage disease type Ib patients of Sardinian origin. This mutation was found to be associated with four sequence variations: c.593 A>T (p.

Long-term outcome and prognostic factors of juvenile dermatomyositis: a multinational, multicenter study of 490 patients.

Objective: To investigate the long-term outcome and prognostic factors of juvenile dermatomyositis (DM) through a multinational, multicenter study.

Methods: Patients consisted of inception cohorts seen between 1980 and 2004 in 27 centers in Europe and Latin America. Predictor variables were sex, continent, ethnicity, onset year, onset age, onset type, onset manifestations, course type, disease duration, and active disease duration.

A specific cystic fibrosis mutation (T3381) associated with the phenotype of isolated hypotonic dehydration.

We carried out molecular screening for mutations in the cystic fibrosis transmembrane regulator (CFTR) gene in eight children of Sardinian descent seen because of hypotonic dehydration associated with hyponatremia, hypochloremia, hypokalemia, and metabolic alkalosis; none had pulmonary or pancreatic involvement. All the patients had the T3381 mutation either in homozygosity or compound heterozygosity with another CF mutation. The T3381 mutation was not detected in patients with CF who had classic symptoms or in healthy persons of the same descent.
