PRECORDIAL PAIN, LEUKOCYTOSIS AND BICYTOPENIA IN A TEENAGER WITH SYSTEMIC JUVENILE IDIOPATHIC ARTHRITIS UNDER IMMUNOSUPPRESSIVE THERAPY.

Objective: To highlight the importance of the new classification criteria for the macrophage activation syndrome (MAS) in systemic juvenile idiopathic arthritis in order to reduce morbidity and mortality outcome related to this disease.

Case Description: A 12-year-old female patient with diagnosis of systemic juvenile idiopathic arthritis under immunosuppression therapy for two years developed cough, acute precordial chest pain, tachypnea, tachycardia and hypoxemia for two days.

Sonographic evaluation of salivary glands in juvenile Sjögren's syndrome.

Unlabelled: IIntroduction: Sjögren's syndrome in childhood is a rare autoimmune disease and mostly under-diagnosed. The aim of this study is to highlight the importance of ultrasonographic assessment of the salivary glands in children with recurrent parotitis and positive autoantibodies. Two cases of ultrasonographic patterns typical of Sjögren's syndrome have been described below.

Osteonecrosis of the jaw on imaging exams of patients with juvenile systemic lupus erythematosus.
