Treatment with hAFS cells has a reparative potential through active involvement of cells in alveolarization and angiogenesis. A downstream paracrine action was also taken into account, in order to understand the immunodulatory response.
Objective: Pneumomediastinum and pneumopericardium are rare occurrences in young athletes, but they can result in potentially life-threatening consequences.Background: While involved in a rugby match, an 11-year-old boy received a chest compression by 3 players during a tackle. He continued to play, but 2 hours later, he developed sharp retrosternal chest pain. A chest radiograph and an echocardiograph at the nearest emergency department showed pneumopericardium and pneumomediastinum.Differential Diagnosis: Sternal and rib contusions, rib fractures, heartburn, acute asthma exacerbation, pneumomediastinum, pneumopericardium, pneumothorax, traumatic tracheal rupture, myocardial infarction, and costochondritis (Tietze syndrome).Treatment: Acetaminophen for pain control. Uniqueness: To our knowledge, this is the only case in the international literature of the simultaneous occurrence of pneumomediastinum and pneumopericardium in a child as a consequence of blunt chest trauma during a rugby match.Conclusions: Pneumomediastinum and pneumopericardium may be consequences of rugby blunt chest trauma. Symptoms can appear 1 to 2 hours later, and the conditions may result in serious complications. Immediate admission to the emergency department is required.
Aggressive parenteral intakes in preterms improve growth and bone status in the short-medium term, suggesting that early nutrition could influence bone development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
