“…Bronchogenic cysts are one of the several bronchopulmonary foregut malformations which arise from abnormal budding during weeks 3–7 of embryological development 1–3 . Despite being rare, these are one of the most common malformations of the lower respiratory tract 2 . The normal development of the respiratory tract means that the most common site for bronchogenic cysts is in the mediastinum (80%) 2 .…”

“…Although clinical presentation may range from asymptomatic to severe respiratory symptoms like biphasic stridor, dyspnea, and cyanosis, congenital tracheal anomalies are often associated with high morbidity and mortality (Chen & Holinger, 1994). These anomalies occur independently or in association with congenital birth defects like Down syndrome, Apert syndrome, Crouzon syndrome, or VACTERL association (Hamilton, Yaneza, Clement, & Kubba, 2016; Schweiger, Cohen, & Rutter, 2016; Zur, 2014). The cause of congenital tracheal anomalies or their relation with other congenital birth defects is not well understood.…”

Development pattern of tracheal cartilage in human embryos

Introduction Congenital tracheal anomalies are associated with high morbidity and mortality. The etiology of congenital tracheal anomalies is not well understood, but often attributed to malformed tracheal cartilage. The development of tracheal cartilage has not been described in detail. In this study, we aimed to investigate the development pattern and timing of normal tracheal cartilage to better understand the etiology of tracheal anomalies. Materials and methods The development of tracheal cartilage was examined by studying the trachea in histological sections of 14 healthy human embryos from the Carnegie collection. Two specimens for Carnegie Stages 17–23 (42–60 days of embryological development) were studied. Results At Carnegie Stages 17–19 (42–51 days), a continuous mesenchymal condensation was observed ventral to the tracheal lumen. At Stages 20 and 21 (51–54 days), this pre‐tracheal mesenchyme showed sites of increased condensation indicative of future tracheal rings. Furthermore, growth centers were identified both proximally and distally in the trachea. Characteristic horseshoe shaped tracheal rings were apparent at Carnegie Stages 22 and 23 (54–60 days). Conclusions In human embryos, tracheal rings arise from growth centers in the ventral mesenchyme at approximately 51–54 days of embryological development. The observation of proximal and distal growth centers suggests a centripetal growth gradient, potentially contributing to occurrence of complete tracheal ring deformity (CTRD). Although this study shows new insights on tracheal cartilage development, the exact origin of congenital tracheal defects has yet to be elucidated.

The OH–NO of Pediatric Foreign Body Ingestions

Foreign body ingestion is a common occurrence in the pediatric population, especially in children less than 5 years old. The innate nature of the young to explore their environment can lead to dangerous ingestions. The clinical challenge is to predict which foreign bodies warrant removal because of risk for serious complications or a low likelihood of spontaneous passage. Lithium batteries, also known as button batteries (BBs), are not a new item, but the incidence of their ingestion is on the rise because of their increasingly common use in household products. In addition, the higher-capacitance 20-mm BB is more likely to lodge in the esophagus and increase morbidity and mortality. This article will describe the frequency of ingestion, which products contain BB, the signs and symptoms of ingestion, diagnostic imaging, mechanism of tissue injury, therapeutic management and intervention, and the complications that affect patient outcomes. The final discussion will address education and anticipatory guidance to prevent these harmful ingestions.
