Pediatric bronchial Dieulafoy's disease with bronchial artery embolization: two case reports.

Background: Bronchial Dieulafoy's disease (BDD) is a vascular malformation characterized by the presence of a dysplastic artery in the bronchial submucosa. It is very rare in children but potentially fatal due to life-threatening hemoptysis.

Case Description: An 8-year-old boy and a 6-year-old girl were referred to our hospital with recurrent moderate to massive hemoptysis.

Case Report: Lessons Learned From Aortic Valve Rupture After Blunt Chest Trauma.

Aortic valve rupture (AVR) due to blunt chest trauma is extremely rare in the pediatric population, and little attention has been paid to such damages. Early diagnosis of AVR may not be easy in patients with multiple competing injuries and poor acoustic windows. We report a case of delayed diagnosis of AVR in a 12-year-old boy after falling from a height of 15 meters, who presented with recurrent hemoptysis and ventilator dependence.

Improvement of the functioning and efficiency of a Code Blue system after training in a children's hospital in China.

Background: Code Blue is a popular hospital emergency code that is used to alert the emergency response team to any medical emergency requiring critical care. By retrospectively studying Code Blue cases in a children's hospital, we looked for high-risk factors associated with survival and how to improve the effectiveness of Code Blue systems through training.

Methods: Data were collected on age, gender, department, diagnosis, time of Code Blue call activation, time between call and arrival of the Code Blue team, treatment details and outcome before and after the training process from January 2016 to December 2019.

Clinical features of capsule endoscopy in 825 children: A single-center, retrospective cohort study.

Video capsule endoscopy (VCE) can detect mucosal lesions in the intestine, especially in the small bowel.Our study aims to evaluate the applications of VCE for pediatric gastrointestinal diseases.In this retrospective study, we included all patients who underwent VCE between December 2012 and December 2018.
