Abstract Thoracic trauma, although rare in children, can lead to significant morbidity and mortality. Most are sustained due to blunt mechanisms, with motor vehicle accidents being most common. Due to…
Abstract Tumors of the chest in the pediatric population represent a large collection of pathologies. They can differ in location from the chest wall, to the mediastinum, to the lung…
Abstract When infants die suddenly and unexpectedly, the causes can be effectively considered using a triple risk model of individual infant susceptibility, developmental vulnerability, and environmental stressors. Sleep practices, particularly…
