Pneumothorax in preterm infants is associated with an increased risk of chronic lung disease, intraventricular hemorrhage and mortality. In mechanically ventilated preterm infants, for the management of tension pneumothorax if needle aspiration is not successful a thoracostomy is needed. In the last two decades management of tension pneumothorax has changed from the use of traditional chest tubes to percutaneous pigtail catheter thoracostomy (PPCT) as the most commonly used technique. When compared to placement of traditional chest tubes, PPCT is touted as being faster requiring, less analgesia and less training for proficiency and having fewer complications...

OBJECTIVES: In preterm infants, the application of nasal Continuous Positive Airway Pressure (nCPAP) improves lung function through several mechanisms and may interact with the control of breathing. Our aim was to evaluate the effect of increasing/decreasing nCPAP on gas exchange, breathing pattern, and its variability in preterm infants. METHODS: Fifeteen infants with mild to moderate respiratory distress syndrome (RDS) were studied on the first day of life. Infants had a mean (SD) gestational age of 30 + 4 (3 + 4) weeks + day and body weight of 1405 (606) g...

OBJECTIVE: Vascular endothelial growth factor (VEGF) and sphingolipid metabolites, sphingosine 1-phosphate (S1P), and ceramides are important to lung development and repair. We hypothesized specific sphingolipid and VEGF alterations would be associated with BPD development and aimed to investigate the early tracheal aspirate (TA) VEGF and S1P relationship with later diagnosis of preterm infant bronchopulmonary dysplasia, BPD. DESIGN: TA VEGF and lipidomics were measured in TA from Infants <32 weeks gestational age at birth with and without later BPD...

BACKGROUND/AIMS: Previous studies have shown that lipopolysaccharide (LPS) exposure may have a protective effect on asthma by reducing airway hyper-responsiveness, airway inflammation and serum IgE levels. However, there are few studies investigating the effect of LPS on mucous secretion in asthma. In this study, we evaluate the relationship between LPS pre-treatment in infant mice and airway mucus hypersecretion in an OVA (ovalbumin)-induced asthma model, and further explore the mechanisms behind this effect...

The heterozygous PHOX2B gene mutation is related to congenital central hypoventilation syndrome (CCHS). It is characterized by defective autonomous nervous system development leading to inadequate breathing response to hypoxia and hypercapnia, leading to hypoventilation especially during non-REM sleep, but also during waking in the more severe cases. Herein we report a case of sudden death in a 28-day-old child. The mother reported the infant was found lying on her own bed in the prone position. The infant was wearing a romper and lying in her crib without any blanket or other objects...

BACKGROUND: Mechanical ventilation causes lung injury and systemic inflammatory responses in preterm sheep, and is associated with bronchopulmonary dysplasia (BPD) in preterm infants. Budesonide added to surfactant decreased BPD by 20% in infants. OBJECTIVE: Determine the effects of budesonide and surfactant on injury from high tidal volume (VT) ventilation in preterm lambs. METHODS: Ewes at 125 {plus minus} 1 day GA had fetal surgery to expose fetal head and chest with placental circulation intact...

Infants born prematurely are particularly susceptible to respiratory illness due to underdeveloped lungs, which can often result in fatality. Preterm infants in acute stages of respiratory illness typically require mechanical ventilation assistance, and the efficacy of the type of mechanical ventilation and its delivery has been the subject of a number clinical studies. With recent advances in machine learning approaches, particularly deep learning, it may be possible to estimate future responses to mechanical ventilation in real-time, based on ventilation monitoring up to the point of analysis...

Tuberculosis (TB) treatment regimens have been extrapolated from adults to children. However, pediatric disease merits different treatment strategies to avoid under- or over-treatment. While animal models have been pivotal in identifying effective regimens for adult disease, pediatric TB is heterogeneous and cannot be represented by a single preclinical model. Infants and young children most commonly have disseminated disease or tuberculous meningitis (TBM), school-aged children have paucibacillary disease, and adolescents have adult-like cavitary lung disease...

Background: Ventilator-induced lung injury with subsequent bronchopulmonary dysplasia remains an important issue in the care of extremely low-birth-weight infants. Permissive hypercapnia has been proposed to reduce lung injury. Hypercapnia changes cerebral perfusion, but its influence on the peripheral microcirculation is unknown. Methods: Data were collected from 12 infants, who were randomized to a permissive high PCO2 target group (HTG) or a control group (CG)...

Aminoacyl-tRNA synthetases (ARSs) are ubiquitously expressed enzymes responsible for charging tRNA with cognate amino acids during protein translation. Non-canonical functions are increasingly recognized, and include transcription and translation control and extracellular signaling. Monoallelic mutations in genes encoding several ARSs have been identified in axonal Charcot-Marie-Tooth (CMT2) disease, whereas biallelic mutations in ARS loci have been associated with multi-tissue syndromes, variably involving the central nervous system, lung, and liver...

Mesenchymal stromal cells (MSCs) are released into the airways of preterm infants following lung injury. These cells display a pro-inflammatory phenotype and are associated with development of severe bronchopulmonary dysplasia (BPD). We aimed to characterize the functional properties of MSCs obtained from tracheal aspirates of 50 preterm infants who required invasive ventilation. Samples were separated by disease severity. The increased proliferative capacity of MSCs was associated with longer duration of mechanical ventilation and higher severity of BPD...

Purpose: Frequent desaturation due to immature incoordination of suck-swallow-breathing in preterm infants can influence multiple organs such as the heart, lungs, and brain, which can then affect growth and development. Most notably in preterm infants, feeding desaturation may even affect pulmonary function during gavage feeding. Because respiratory muscle activities may reflect the work required during respiration, we evaluated the differences in these activities between full-term and preterm infants with feeding desaturation, and investigated the correlations with clinical variables...
