EditorialThe global burden of respiratory disease-impact on child health.
Respiratory disease is the major cause of mortality and morbidity worldwide, with infants and young children especially susceptible. The spectrum of disease ranges from acute infections to chronic non-communicable diseases. Five respiratory conditions dominate-acute respiratory infections, chronic obstructive pulmonary disease, asthma, tuberculosis (TB), and lung cancer. ⋯ The Forum of International Respiratory Societies (FIRS), representing the major respiratory societies worldwide, has produced a global roadmap of respiratory diseases, Respiratory Disease in the World: Realities of Today-Opportunities for Tomorrow. This highlights the burden of respiratory diseases globally and contains specific recommendations for effective strategies. Greater availability and upscaled implementation of effective strategies for prevention and management of respiratory diseases is needed worldwide to improve global health and diminish the current inequities in health care worldwide.

Asthma is the most common chronic disorder of childhood and continues to be a leading cause of pediatric hospital admission. The National Asthma Education and Prevention Program (NAEPP) recommends that spirometry be obtained for asthma patients upon hospital admission, after bronchodilation during the acute phase of asthma symptoms, and at least one additional time before discharge from the hospital. The objectives of this study were to describe the use of spirometry in children hospitalized with asthma and to determine association of pulmonary function with future exacerbations. ⋯ Nevertheless, separate logistic regression models found that FEV1 /FVC and FEF25-75 were not associated with re-exacerbation when adjusted for age and length-of-stay. We found that few children admitted with asthma had spirometry as recommended in the NAEPP guidelines unless recommended by specialists and both lower lung function (FEV1 /FVC and FEF25-75 ) and history of more frequent and more recent prior health-care utilization for asthma were associated with repeat asthma exacerbation. However, the value of performing spirometry on asthmatic children prior to hospital discharge remains unclear and will require prospective study.

Chronic suppurative lung disease in a developing country: impact on child and parent.
To investigate the impact of chronic suppurative lung disease (CSLD) on growth and lung function in the child as well as quality of life of the child and parent. ⋯ CSLD had a negative impact on growth, lung function, and quality of life. Children with CF had a better outcome in growth as well as better parental mental health compared to children with other etiologies. Pediatr Pulmonol. 2014; 49:435-440. © 2013 Wiley Periodicals, Inc.

Serum metabolomics indicate altered cellular energy metabolism in children with cystic fibrosis.
Cystic fibrosis (CF) is a multi-system disease affecting multiple organs and cells besides the respiratory system. Metabolomic profiling allows simultaneous detection of biochemicals originating from cells, organs, or exogenous origin that may be valuable for monitoring of disease severity or in diagnosis. ⋯ Serum metabolomics discriminated CF from non-CF and show altered cellular energy metabolism in CF potentially reflecting mitochondrial dysfunction. Future studies are indicated to examine their relation to the underlying CF defect and their use as biomarkers for disease severity or for cystic fibrosis transmembrane regulator (CFTR) function in an era of CFTR modifying drugs.

Viral croup is a frequent disease in early childhood. Although it is usually self-limited, it may occasionally become life-threatening. Mild croup is characterized by the presence of stridor without intercostal retractions, whereas moderate-to-severe croup is accompanied by increased work of breathing. ⋯ Nebulized budesonide (2 mg) can be given alternatively to children who do not tolerate oral dexamethasone. Exposure to cold air or administration of cool mist are treatment interventions for viral croup that are not supported by published evidence, but breathing heliox can potentially reduce the work of breathing related to upper airway obstruction. In summary, corticosteroids may decrease the intensity of viral croup symptoms irrespective to their severity on presentation to the emergency department.
