Comparative Study
[Clinical, echocardiographic and prognostic profile of Streptococcus viridans left-sided endocarditis].
Published case series on Streptococcus viridans endocarditis are scarce and outdated. The aims of our study were multiple: to analyze the profile of the Streptococcus viridans endocarditis, to compare it with other types of left-sided endocarditis and with cases caused by Staphylococcus aureus, and to determine predictors of poor outcome in Streptococcus viridans endocarditis. ⋯ Although Streptococcus viridans is a nonaggressive microorganism, valvular destruction is similar to that caused by other pathogens when it causes left-sided endocarditis. Nonetheless its prognosis is better, a feature which may be related to the fact that the systemic infectious syndrome can be treated more effectively. Prognostic factors in left-sided endocarditis due to Streptococcus viridans are heart failure and periannular complications.

Pneumopericardium is an uncommon but potentially serious condition. It appears in association with invasive diagnostic and therapeutic procedures, although cases have also been reported in association with bronchospasm, esophageal disorders, and other problems. We describe a case of spontaneous pneumopericardium with chest pain in a patient with community-acquired pneumonia.
