Sputum Induction in Children Is Feasible and Useful in a Bustling General Hospital Practice.

We prospectively studied the feasibility and effectiveness of sputum induction in obtaining good quality sputum and its subsequent bacterial yield in children with clinically suspected acute lower-respiratory-tract infection (aLRTI). Good quality sputum was collected in 89/98 (91%) patients. Sputum cultures revealed ≥1 bacterial pathogens in 22 cases (25%).

The effect of 3% and 6% hypertonic saline in viral bronchiolitis: a randomised controlled trial.

Bronchiolitis is a common disorder in young children that often results in hospitalisation. Except for a possible effect of nebulised hypertonic saline (sodium chloride), no evidence-based therapy is available. This study investigated the efficacy of nebulised 3% and 6% hypertonic saline compared with 0.

Four of a kind: asthma control, FEV1, FeNO, and psychosocial problems in adolescents.

Background: Many adolescents have poor asthma control and are at high risk for psychosocial problems. However, structured assessment of asthma control or psychosocial problems is still not implemented in routine asthma care. Pediatricians typically rely on their clinical view and physiological measurements.

Nocturnal apnea in Chiari type I malformation.

Unlabelled: A 4-year-old girl presented with sleep-disordered breathing. Her parents described breathing pauses of up to 20 s and progressive tiredness during the day. Obstructive apneas from an enlarged adenoid were thought to be the most probable cause.

An asthma-related quality of life instrument is unable to identify asthmatic children with major psychosocial problems.

Evidence shows that psychosocial problems among children and adolescents with asthma interfere with adherence to treatment and therefore need attention in asthma care. It is unknown whether the already frequently implemented asthma-related quality of life (QoL) instruments reflect psychosocial problems in children with asthma. The aim of this study was to assess the relationship between asthma-related QoL and psychosocial problems and to determine whether an asthma-related QoL instrument is able to identify those children and adolescents with asthma with major psychosocial problems.

Structural lung changes, lung function, and non-invasive inflammatory markers in cystic fibrosis.

Cystic fibrosis (CF) lung disease is characterized by chronic airway inflammation and recurrent infections, resulting in (ir)reversible structural lung changes and a progressive decline in lung function. The objective of this study was to investigate the relationship between non-invasive inflammatory markers (IM) in exhaled breath condensate (EBC), lung function indices and structural lung changes, visualized by high resolution computed tomography (HRCT) scans in CF. In 34 CF patients, lung function indices (forced expiratory volume in 1 s, forced vital capacity [FVC], residual volume, and total lung capacity [TLC]) and non-invasive IM (exhaled nitric oxide, and condensate acidity, nitrate, nitrite, 8-isoprostane, hydrogen peroxide, interferon-gamma) were assessed.

No differences in physical activity in (un)diagnosed asthma and healthy controls.

To establish whether asthma affects physical activity levels in children (aged 7-10 years) we evaluated physical activity levels in children with undiagnosed asthma (UDA), diagnosed asthma (DA), and healthy controls (HCs). A cross-sectional community-based study was performed which included a parental questionnaire on their child's respiratory health, and testing of airway reversibility and bronchial hyperresponsiveness (BHR). DA was defined as the parents' confirmation of a physician's diagnosis of asthma in the past 12 months.

Quality of life in children with undiagnosed and diagnosed asthma.

This study describes the impact of undiagnosed and diagnosed asthma on quality of life in schoolchildren aged 7-10 years and their caregivers in a cross-sectional community-based study. Diagnosed asthma was defined as the parents' confirmation of a physician's diagnosis of asthma. Undiagnosed asthma was defined by asthma symptoms combined with airway reversibility or bronchial hyperresponsiveness.

Excessive body weight is associated with additional loss of quality of life in children with asthma.

Background: Asthma and excessive body weight frequently coexist, whereas the exact relationship between the 2 diseases is unknown.

Objective: To study whether asthma combined with excessive body weight has a greater effect on quality of life in children than the separate effects of asthma or excessive body weight alone.

Methods: In a cross-sectional design, 1758 school children (age 7-10 years) participated: 4 study groups were composed of children with asthma and with/without excessive body weight, and healthy controls with/without excessive body weight.
