Childhood myocarditis and parvovirus B19 genotypes.

Background: Human parvovirus B19 (PVB19) infection is occasionally associated with acute myocarditis. Three cases of children with PVB19 virus-associated myocarditis occurred in a very short period and the same geographical region.

Objective: To elucidate if virological factors could be responsible for determining the course of infection, a molecular epidemiologic investigation was performed.

Successful pulmonary embolectomy in a 4-year-old girl with antithrombin III deficiency.

We report the case of a 4-year-old girl, successfully treated by surgical pulmonary embolectomy for acute massive pulmonary embolism. She was known to have a congenital antithrombin III deficiency diagnosed after a familial history of thromboembolic events. Surgical embolectomy may be considered as a treatment option in selected patient with anatomically extensive pulmonary embolism.
