Childhood-Onset Takayasu Arteritis: Clinical Features of Disease and Relapse Risk Factors.

Takayasu's arteritis (TA) is a systemic vasculitis that primarily affects the aorta and major arteries. Despite aggressive treatment with glucocorticoids (GCs) and non-biological disease-modifying antirheumatic drugs (nbDMARDs), about 30% of patients experience resistance to therapy or relapse. This study aimed to identify risk factors associated with refractory and relapse TA in pediatric patients.

ORAL MANIFESTATIONS IN JUVENILE SCLERODERMA: CLINICAL PRESENTATIONS AND HISTOPATHOLOGICAL CHARACTERISTICS.

Juvenile scleroderma (JS) is a rare chronic connective tissue disorder characterized by stiffening of the skin and soft tissues, including the oral cavity and perioral tissues, leading to fibrosis and a large spectrum of internal organs involvement, cosmetic defects, and early infant disability. The aim of this study was to investigate the histomorphological features of lesions of oral mucosa tissues in children with juvenile scleroderma (JS). 39 JS patients (9 with juvenile systemic sclerosis - JSS and 20 with juvenile scleroderma of head-JSH aged from 5 to 17 years were observed with dental examination and morphological investigation of the dental mucosa.

Mechanisms of Long-Term Persistence of Mycoplasmas in Children with Asthma.

Improving the management of children with asthma associated with mycoplasma infection is important. Aim: To study the duration of the persistence of antigens, and DNA in a free state, in the structures of circulating immune complexes (CICs) and living cells of and in children with asthma. In total, 205 children with asthma from 1 to 14 years were observed.

The Common Cold and Influenza in Children: To Treat or Not to Treat?

The common cold, which is mostly caused by respiratory viruses and clinically represented by the symptoms of acute respiratory viral infections (ARVI) with mainly upper respiratory tract involvement, is an important problem in pediatric practice. Due to the high prevalence, socio-economic burden, and lack of effective prevention measures (except for influenza and, partially, RSV infection), ARVI require strong medical attention. The purpose of this descriptive literature review was to analyze the current practical approaches to the treatment of ARVI to facilitate the choice of therapy in routine practice.

The Role of Transcription Factor PPAR-γ in the Pathogenesis of Psoriasis, Skin Cells, and Immune Cells.

The peroxisome proliferator-activated receptor PPAR-γ is one of three PPAR nuclear receptors that act as ligand-activated transcription factors. In immune cells, the skin, and other organs, PPAR-γ regulates lipid, glucose, and amino acid metabolism. The receptor translates nutritional, pharmacological, and metabolic stimuli into the changes in gene expression.
