Chronic recurrent multifocal osteomyelitis with concomitant features of juvenile idiopathic arthritis.

We report a case of a 13-year-old girl with chronic recurrent multifocal osteomyelitis (CRMO) who developed severe arthritis in four different joints within the first year from the onset of the disease. Her multiple vertebrae lesions showed significant amelioration after a 2-month treatment with prednisolone. In parallel, the initial severe symmetrical arthritis of both knees showing overt synovitis and joint effusion, in the absence of lesions in the metaphyses of the femur or the tibia, responded remarkably well in intra-articular triamcinolone hexacetonide injections.

Midline carcinoma of children and young adults with NUT rearrangement.

Purpose: A balanced chromosomal translocation, t(15;19), resulting in the BRD4-NUT oncogene, has been identified in a lethal carcinoma of young people, a disease described primarily in case reports. We sought to amass a more definitive series of tumors with NUT and/or BRD4 gene rearrangements and to determine distinct clinicopathologic features.

Patients And Methods: Carcinomas (N = 98) in young individuals (median age, 32.

Encephalitis and myocarditis in a child with acute lymphoblastic leukemia: role of coxsackievirus B5?

Enteroviruses are common causes of viral encephalitis in childhood and the most common cause of myocarditis. The prognosis is good with exception of the immunocompromised children who are at higher risk with increased mortality. A case of a 7-year-old boy with acute lymphoblastic leukemia and coxsackievirus B5-associated encephalitis and myocarditis is described.
