BACKGROUND: Small airway hyperresponsiveness is a critical aspect in preschool children with asthmatic symptoms interms of asthma control. The aim of this study was to elucidate the relationship of changes in reactance (Xrs) and resistance (Rrs) of IOS and FEV1 with those in clinical parameters and to determine which IOS parameter is correlated with bronchial hyperresponsiveness before positive clinical endpoints. METHODS: We performed the methacholine challenge test in ninety-four preschool children (4...

BACKGROUND: Advances in perinatal care have markedly increased the prospects of survival for infants born extremely preterm (EP). The aim of this study was to investigate hospitalisation rates and respiratory morbidity from five to 11 years of age in a prospective national cohort of EP children born in the surfactant era. METHODS: This was a national prospective cohort study of all children born in Norway during 1999 and 2000 with gestational age (GA) < 28 weeks or birth weight < 1000 grams, and of individually matched term-born controls recruited for a regional subsample...

BACKGROUND: The use of cuffed vs uncuffed endotracheal tubes in pediatric anesthesia is widely debated. This study aimed to investigate whether the use of cuffed vs uncuffed tubes is associated with an increased incidence of acute postoperative respiratory complications. METHODS: We retrospectively studied all children aged 0-7 years in which the trachea was intubated between September 28, 2006 and August 26, 2016 in a pediatric university hospital. Logistic regression analysis was performed to estimate the association between tube design (cuffed vs uncuffed) and the incidence of acute postoperative respiratory complications (stridor, wheezing, or dyspnea; desaturations ≤90%) in need of intervention (epinephrine, dexamethasone, nebulizers, supplementary oxygen, or reintubation), adjusting for potential confounders...

Spontaneous pneumomediastinum is defined as free air or gas contained within the mediastinum, which almost invariably originates from the alveolar space or the conducting airways. It is rare in pediatric patients; however, occasional cases are reported to result from forced Valsalva's maneuver due to cough, emesis, a first attack of wheeze, or asthma exacerbations. We report the case of a 7-year-old previously healthy girl, with a history of persistent dry cough one day before, who was brought to our unit with face, neck and chest swelling...

OBJECTIVE: Children with asthma-like symptoms may not clinically wheeze. The objectives of this study were to evaluate if children, without physician-documented wheeze, wheeze during bronchial-challenge-testing (BCT), and if measurements of O2 Sat and respiratory rate during BCT improve the BCT sensitivity? METHODS: Seven hundred and twenty-four children, who were referred for suspicion of asthma, performed a BCT. Positive BCT was determined by the provocation concentration (PC) which resulted in a 20% decrease in FEV1 (PC20 ), (in those who were able to perform spirometry, group B), or (in those unable to perform spirometry, group A) a 50% increase in respiratory rate (PCRR ), or a 5% decrease in oxygen-saturation (PCO2-Sat ) or appearance of wheezing (PCwheeze )...

Background: Indoor air pollution (IAP) and environmental tobacco smoke (ETS) are associated with lower respiratory tract illness (LRTI) or wheezing in children. However, the effect of the timing of these exposures, specifically antenatal versus postnatal, and of alternate fuel sources such as the increasingly used volatile organic compounds have not been well studied. We longitudinally investigated the effect of antenatal or postnatal IAP and ETS on LRTI or wheezing prevalence and severity in African infants...

Background and objectives: Exacerbations are important outcomes in COPD both from a clinical and an economic perspective. Most studies investigating predictors of exacerbations were performed in COPD patients participating in pharmacological clinical trials who usually have moderate to severe airflow obstruction. This study was aimed to investigate whether predictors of COPD exacerbations depend on the COPD population studied. Methods: A network of COPD health economic modelers used data from five COPD data sources - two population-based studies (COPDGene® and The Obstructive Lung Disease in Norrbotten), one primary care study (RECODE), and two studies in secondary care (Evaluation of COPD Longitudinally to Identify Predictive Surrogate Endpoint and UPLIFT) - to estimate and validate several prediction models for total and severe exacerbations (= hospitalization)...

The relationship between asthma and sleep-disordered breathing is bidirectional due to common risk factors that promote airway inflammation. Obstructive sleep-disordered breathing and recurrent wheeze/asthma are conditions that involve the upper and the lower respiratory system, respectively. The aim of the present study was to investigate the sleep disordered breathing in children with recurrent wheeze/asthma. This was a retrospective study concerning children older than 2 years who underwent-between January 2014 and November 2016-an in-laboratory overnight polygraphic study...

Although it is necessary and part of standard practice, supplemental oxygen (40-90% O2) or hyperoxia is a significant contributing factor to development of bronchopulmonary dysplasia, persistent pulmonary hypertension, recurrent wheezing, and asthma in preterm infants. This chapter discusses hyperoxia and the role of redox signaling in the context of neonatal lung growth and disease. Here, we discuss how hyperoxia promotes dysfunction in the airway and the known redox-mediated mechanisms that are important for postnatal vascular and alveolar development...

BACKGROUND: Spontaneous pneumomediastinum most relevant triggering events are cough, vomiting, nutritional problems, physical activity and use of inhaled drugs. Association of spontaneous pneumomediastinum with non-asthma-related bronchospasm is an infrequent event. CLINICAL CASE: This is the case of a 21-year-old woman without personal or family history of asthma, allergic rhinitis or atopy who during late puerperium had 39 °C fever, paroxysmal cough and chest oppression of sudden onset, as well as wheezing and subcutaneous emphysema of the neck; she had no previous nasal symptoms...

A 62-year-old man with asthma presented with a 1-month history of wheezing and exertional dyspnea. Although the wheezing symptoms disappeared after systemic corticosteroid therapy, the exertional dyspnea and hypoxemia did not improve. A diagnosis of intravascular large B-cell lymphoma (IVLBCL) with pulmonary involvement was suspected because of the increased serum lactic dehydrogenase (LDH) and soluble interleukin-2 receptor (sIL-2R) level, increased alveolar-arterial oxygen difference (AaDO2), decreased pulmonary diffusing capacity for carbon monoxide (DLCO) and scintigraphic, computed tomography (CT) and (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET)-CT findings...

INTRODUCTION: Advances in molecular diagnosis have made it possible to detect previously unknown viral agents as causative agents of lower respiratory tract infections (LRTI). The frequency and relevance of viral coinfections is still debatable. OBJECTIVE: compare clinical presentation and severity between single virus infection and viral coinfection in children admitted for LRTI. METHODS: A 3-year period observational study (2012-2015) included children younger than two years admitted for LRTI...

REVIEW
I Chkhaidze, D Zirakishvili
Bronchiolitis is a common condition in children less than 2 years of age and is a leading cause of infant hospitalization. Acute bronchiolitis is characterized by acute wheezing in infants or children and is associated with signs or symptoms of respiratory infection; the most common etiologic agent is respiratory syncytial virus. There is a lack of consensus regarding the clinical definition of acute viral bronchiolitis in children and hence the management varies across the globe. Usually it does not require investigation, treatment is merely supportive and a conservative approach seems adequate in the majority of children, especially for the youngest ones...
