Delayed cardiac tamponade is a rare phenomenon with two primary causes: delayed hemorrhage after an acute injury or delayed pericarditis with effusion. We present a case of cardiac tamponade 4 weeks after injury, with findings compatible with delayed hemorrhage and pericarditis. Our case emphasizes the need for follow-up of patients with penetrating chest trauma for several months after injury; echocardiography should be used if symptoms of tamponade appear.

Randomized Controlled Trial Clinical TrialEMLA cream as a topical anesthetic before office phlebotomy in children.
We studied the effectiveness of EMLA cream (2.5% lidocaine, 2.5% prilocaine) in reducing distress, anxiety, and pain associated with phlebotomy in pediatric outpatients. This was a randomized, double-blind, placebo-controlled study using EMLA cream or placebo 1 hour before phlebotomy. Distress, anticipatory anxiety, pain, and adverse reactions were measured. ⋯ Pain was decreased with use of EMLA cream. Anticipatory anxiety levels were equal within both groups. Ratings of cream efficacy by parent/observer scales were in favor of EMLA cream.
