Improvement of the Etiological Diagnosis of the Pericarditis
Improvement of the Etiological Diagnosis of the Pericarditis
Pericardial syndrome includes pericardites acute pericardial effusion and cardiac tamponade,
 recurrent pericarditis squeezing chronic pericarditis. The etiologies are very numerous and
 can be classified as infectious, neoplastic, metabolic or systemic, toxic causes. Diagnosis
 is difficult, and 80% of etiologies remain classified idiopathic. In their laboratory to
 improve the diagnosis of this syndrome investigators have developed a strategy of systematic
 prescription of biological tests by kit. This prescription by 'kit' strategy proved its
 interest by comparison with an intuitive requirement of biological. In this study
 investigators want to improve the diagnostic causative of pericarditis by implementing a new
 diagnostic strategy. This new strategy includes (i) samples additional less invasive for the
 patient, the swab pharyngeal and nasal, (ii) the addition of at the outset of more effective
 diagnostic techniques: specific Polymerase Chain Reaction (PCR)
