Abstract

The benefits of transesophageal echocardiography (TEE) may depend on the clinical likelihood of infective endocarditis, but little data exist on patients at low risk. We studied 32 patients with renal failure with either a low (n = 21) or high (n = 11) level of clinical suspicion for infective endocarditis. In the low-risk cases, TEE provided no new information whether the transthoracic echo was normal or abnormal, although it did confirm that an echogenic mass was more likely to be a calcific deposit than a vegetation. In the high-risk cases, transthoracic echocardiography was always abnormal but TEE added new information in seven out of 11 cases-positively in six, and by exclusion in one. TEE detected signs of complications of infective endocarditis in one case. We conclude that, when the clinical suspicion of endocarditis is low, TEE is rarely necessary.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
