Pericardial Effusion Causing Cardiac Tamponade in a 10-Year-Old Male.

A 10-year-old male with a past medical history of premature pubarche, mild persistent asthma, and eczema presented to the emergency department with progressive dyspnea and chest pain. On examination, he was found to be tachycardic and tachypneic. Chest radiograph demonstrated cardiomegaly, bilateral pleural effusions, and scattered atelectasis.

Retrospective cohort study of individuals born with low birthweight: implications for screening practices.

Background: Previous studies have established an association between low birthweight (LBW) and future kidney disease, but few have explored the progression of kidney dysfunction through the pediatric years leading up through adolescence and young adulthood.

Methods: To better understand the temporal effects of birthweight on kidney disease progression, we conducted a retrospective cohort study comparing the glomerular filtration rate (GFR) between LBW (<2500 grams) and normal birthweight (NBW) infants who were admitted to the neonatal intensive care unit (NICU) at our institution from 1992 to 2006.

Results: Age at follow-up ranged 1-26 years old.
