The Greek 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 Greek language. The reading comprehension of the questionnaire was tested in 10 JIA parents and patients.

Rare Variants in Juvenile Idiopathic Arthritis and Primary Antibody Deficiencies.

Sialic acid acetylesterase (SIAE) deficiency was suggested to lower the levels of ligands for sialic acid-binding immunoglobulin-like receptors, decreasing the threshold for B-cell activation. In humans, studies of rare heterozygous loss-of-function mutations in gene in common autoimmune diseases, including juvenile idiopathic arthritis (JIA), yielded inconsistent results. Considering the distinct pathogenesis of the two main subtypes of JIA, autoinflammatory systemic (sJIA) and autoimmune oligo/polyarticular (aJIA), and a predisposition to autoimmunity displayed by patients and families with primary antibody deficiencies (PADs), the aim of our study was to analyze whether rare variants are associated with both the phenotype of JIA and the autoimmunity risk in families with PADs.

Fournier's Gangrene Associated with Local Cutaneous HPV Lesions in a Previously Healthy Girl.

A case of an 11-year-old prepubertal girl with Fournier's gangrene is presented. The diagnosis was posed after the disease had progressed to the typical clinical picture of frank gangrene. A benign viral infection, common warts, possibly represents the initiating event of the development of this necrotizing soft tissue infection.

Functional estrogen receptors alpha and beta are expressed in normal human salivary gland epithelium and apparently mediate immunomodulatory effects.

Salivary gland epithelial cells (SGECs) have been shown to participate in immunological responses and have been implicated in the pathogenesis of Sjögren's syndrome (SS). Experimental evidence from animal models indicates that estrogen deficiency may also participate in SS pathogenesis. However, the expression and functionality of the estrogen receptors alpha (ERalpha) and beta (ERbeta) in normal human salivary epithelium is unknown.
