Infants with persistent wheeze is a common diagnostic challenge for the general pediatrician because of the broad differential diagnoses. The initial diagnostic approach should include a comprehensive history, physical examination, and chest radiography. Additional testing may be warranted. Involvement of a pediatric pulmonary subspecialist may also be indicated. [Pediatr Ann. 2019;48(3):e110-e114.].

Overnight analysis of tidal breathing flow volume loops (TBFV), recorded by impedance pneumography (IP), has been successfully applied in the home monitoring of children with wheezing disorders. However, little is known on how sleep physiology modifies the relationship between TBFV profiles and wheeze. We studied such interactions in wheezing infants. 43 infants recruited due to recurrent lower airway symptoms were divided into 3 groups based on their risk of asthma, i.e. high (HR), intermediate (IR) or low (LR)...

The prevalence of the asthmatic symptoms among children increases globally over the time. Reduced exposure to pathogens in early childhood and increased exposure to anthropogenic irritants result in increased risk of wheezing in children, and all of this may be related to the usage of household chemicals. Objective of this analysis thus was to study the potential effects of overall exposure to home chemicals in the early life on the phenotypes of wheezing from birth until five years of age. 3411 mother-infant pairs from the Czech part of the European Longitudinal Study of Pregnancy and Childhood (ELSPAC-CZ) participated in the study...

BACKGROUND: Clinically, asthma in children under 5 years old is under estimated because lack of diagnostic criteria. The current study was, therefore, designed to identify the predicting factors for recurrent wheezing in infants. METHODS: One hundred forty-five infants under 3-year old hospitalized with respiratory diseases were enrolled into this study. Patients were followed up for one-year period after being discharged from the hospital and were, then, divided into recurrent wheezing group and non-recurrent wheezing group based on whether there was recurrent wheezing or not...

OBJECTIVE: The increased social and economic burdens for asthma in infants make the prevention of asthma a major public health goal. Probiotics may reduce the risk of asthma in infants. However, randomized controlled trials (RCTs) have shown mixed efficacy outcomes. We performed a meta-analysis of RCTs to investigate whether probiotics are associated with a lower asthma incidence in infants. METHODS: The PubMed, Cochrane library, and EMBASE databases were systematically searched from the inception dates to August 2018...

Severe respiratory syncytial virus (RSV) infection during infancy is associated with ongoing respiratory morbidity. In a large birth cohort of 2210 healthy preterm infants born at 32-35 weeks of gestation, we aimed to determine the role of atopy in the link between RSV hospitalization and current wheeze at age 6. We defined current wheeze as parent-reported wheeze or the use of respiratory medication in the past 12 months. Based on a positive family history of atopic disease, we distinguished between children with and without atopic predisposition...

Asthma is a common disease with increasing prevalence both in children and adults. WHO estimates that annually 15 million disability-adjusted life-years are lost and 250,000 asthma deaths are reported worldwide. Approximately 500,000 annual hospitalizations are due to asthma. To study the Relationship between environmental factors and childhood asthma has been studied. Maternal stress during pregnancy might affect fetal lung development and subsequently predispose to childhood asthma. The aim of the study was to assess the associations of maternal psychological stress during pregnancy and identify environmental correlates of the conditions with childhood asthma...

PURPOSE OF REVIEW: To review the literature of the past 18 months (April 2017 through September, 2018) relating to vitamin D and childhood asthma. RECENT FINDINGS: A combined analysis of two clinical trials of maternal vitamin D supplementation trials showed a significant protective effect of vitamin D supplementation trials in the primary prevention of asthma and recurrent wheeze up to age 3 years. Secondary analyses from these trials have also suggested that initial maternal vitamin D status could affect the response to supplementation during pregnancy, with the biggest protective effect in children born to mothers with initial 25hydroxyvitamin D (25OHD) levels of at least 30 ng/ml...

BACKGROUND: Passive immunization against RSV (Respiratory Syncytial Virus) is given in most western countries (including Israel) to infants of high risk groups such as premature babies, and infants with Congenital Heart Disease or Congenital Lung Disease. However, immunoprophylaxis costs are extremely high ($2800-$4200 per infant). Using cost-utility analysis criteria, we evaluate whether it is justified to expand, continue or restrict nationwide immunoprophylaxis using palivizumab of high risk infants against RSV...

Respiratory syncytial virus (RSV) is a leading cause of hospitalization of infants and young children causing considerable respiratory disease and repeat infections that may lead to chronic respiratory conditions such as asthma, wheezing, and bronchitis. RSV causes ∼34 million new episodes of lower respiratory tract illness (LTRI) in children younger than 5 years of age with >3 million hospitalizations due to severe RSV-associated LRTI. The standard of care is limited to symptomatic relief as there are no approved vaccines and few effective antiviral drugs, thus a safe and efficacious RSV therapeutic is needed...
