Serum oxidative stress parameters and paraoxonase-1 in children and adolescents exposed to passive smoking.

Background: Exposure to secondhand smoke is too common in many countries. The mechanism of the detrimental effects of passive smoking on childhood health, however, is poorly described. The purpose of this study was therefore to examine the effect of passive smoking on total antioxidant status (TAS), total oxidant status (TOS), and paraoxonase-1 in children compared with healthy non-passive smokers.

Vitamin D-containing supplements for children between 1-3 years of age: are they essential for bone health?

Objective: We aim to evaluate how vitamin D-containing supplements affect the vitamin D status of children 1-3 years old and to assess the variation of the vitamin D concentrations across different seasons.

Methods-material: This retrospective study included a review of medical reports of 1035 patients (aged 1-3 years) who presented to our hospital between October 2011 and October 2013. The children were divided into 3 groups: Group 1: those supplemented with vitamin D₃ (400 IU/day), Group 2: those supplemented with multivitamins, which included 200-400 IU/day of vitamin D₂ or D₃, and Group ₃, the controls: those not supplemented with vitamin D.

The relationship between psychological symptoms, lung function and quality of life in children and adolescents with non-cystic fibrosis bronchiectasis.

Objectives: The aim of this study was to evaluate the relationship between psychological symptoms and quality of life (QOL) and clinical variables in a cohort of children and adolescents with non-cystic fibrosis (non-CF) bronchiectasis.

Methods: Seventy-six patients (aged 8-17years) participated in this study. Questionnaires were used to evaluate the psychological status and QOL of the patients and healthy controls.
