Pediatrician's approach to diagnosis and management of group A streptococcal pharyngitis.

Group A streptococcal (GAS) pharyngitis is responsible for 20-30% of pharyngitis cases in children (Shulman et al. Clin Infect Dis 55(10):e86-e102, 2012). Recommendations for the diagnosis and treatment of GAS pharyngitis have been published by the Italian National Institute of Health guidelines in 2012 (ESCMID Sore Throat Guideline Group et al.

Disease activity and damage in juvenile idiopathic arthritis: methotrexate era versus biologic era.

Objective: To compare the long-term disease state, in terms of activity and damage, of children with juvenile idiopathic arthritis (JIA) who had their disease onset in methotrexate (MTX) or biologic eras.

Methods: Patients were included in MTX or biologic era cohort depending on whether their disease presentation occurred before or after January 2000. All patients had disease duration ≥ 5 years and underwent a prospective cross-sectional assessment, which included measurement of disease activity and damage.

MBL2 and FCN2 gene polymorphisms in a cohort of Italian children with rheumatic fever: A case-control study.

Background: Mannose-binding lectins and human ficolins are pattern-recognition proteins involved in innate immunity. A role for MBL2 and FCN2 gene polymorphisms in the pathogenesis of recurrent severe streptococcal infections and rheumatic carditis has been suggested.

Objectives: The aim of this study is to evaluate the presence of MBL2 and FCN2 gene polymorphisms (SNPs) in children with a history of rheumatic fever (RF) and to investigate their possible role in RF clinical presentation and disease course.

Clinical characteristics of juvenile idiopathic arthritis in an area of central Italy: a population-based study.

Background: Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in children and an important cause of short and long-term disability. In a recent systematic review of population based studies, the epidemiology of JIA is variable worldwide with incidence rates ranging between 1.6 and 23.

Intra-articular corticosteroids versus intra-articular corticosteroids plus methotrexate in oligoarticular juvenile idiopathic arthritis: a multicentre, prospective, randomised, open-label trial.

Background: Little evidence-based information is available to guide the treatment of oligoarticular juvenile idiopathic arthritis. We aimed to investigate whether oral methotrexate increases the efficacy of intra-articular corticosteroid therapy.

Methods: We did this prospective, open-label, randomised trial at ten hospitals in Italy.
