[Chronic nonbacterial osteomyelitis: description of three pediatric cases.].

Chronic recurrent multifocal osteomyelitis (CRMO) or also called chronic non-bacterial osteomyelitis (CNO) is the most common autoinflammatory bone disease. It is characterized by the presence of symptomatic and non-symptomatic bone lesions, mono or multifocal. The main sites involved are the metaphyses of the long bones, the bones of the pelvis, the vertebrae, the clavicle, the mandible.

Non-coronary cardiac events, younger age, and IVIG unresponsiveness increase the risk for coronary aneurysms in Italian children with Kawasaki disease.

Objectives: Kawasaki disease (KD) is the most frequent cause of acquired heart disease in children in high-income countries because of coronary artery involvement. Risk factors for coronary lesions can vary in consideration of different genetic background and environmental factors.

Methods: Multicenter retrospective and prospective study including 372 consecutive children (58% boys; mean age 34.

Infrared thermography in children: a reliable tool for differential diagnosis of peripheral microvascular dysfunction and Raynaud's phenomenon?

Background: Infrared Thermography (IRT) has been used for over 30 years in the assessment of Raynaud Phenomenon (RP) and other peripheral microvascular dysfunctions in adults but, to date, very little experience is available on its use in children for this purpose. The first aim of the study was to assess reproducibility of thermographic examination after cold exposure by comparing inter-observer agreement in thermal imaging interpretation. The secondary aim was to evaluate whether IRT is reliable to diagnose and differentiate peripheral circulation disturbances in children.

Extreme thrombocytosis in systemic juvenile idiopathic arthritis. A case report.

Background: Systemic onset juvenile idiopathic arthritis (SoJIA) is a rare inflammatory disorder characterized by remitting fevers, evanescent rash, generalized lymphadenopathy, hepatomegaly/splenomegaly, and/or serositis.

Case Presentation: Here we report the case of a 5 years-old girl with SoJIA complicated by severe thrombocytosis. Treatment with the Interleukin-1β (IL-1β) receptor antagonist Anakinra caused a fast reduction of blood platelets and of the associated systemic inflammatory response.
