Methicillin-Resistant as a Probable Cause of Antibiotic-Associated Enterocolitis.

Antibiotic-associated diarrhea is typically associated with . However, has also been described as a cause of antibiotic-associated enterocolitis and diarrhea and is likely an underrecognized etiology. We present a case of enterocolitis and urinary tract infection caused by methicillin-resistant following antibiotic treatment.

High-Value, Cost-Conscious Care: Iterative Systems-Based Interventions to Reduce Unnecessary Laboratory Testing.

Background: Inappropriate testing contributes to soaring healthcare costs within the United States, and teaching hospitals are vulnerable to providing care largely for academic development. Via its "Choosing Wisely" campaign, the American Board of Internal Medicine recommends avoiding repetitive testing for stable inpatients. We designed systems-based interventions to reduce laboratory orders for patients admitted to the wards at an academic facility.

Clinical Importance of Echogenic Swirling Pleural Effusions.

Thoracic sonography is an important tool in diagnosis and assessment of pleural effusions and can provide valuable information about the characteristics of accumulated pleural fluid, in addition to improving the safety of thoracentesis. In addition to the 4 classic sonographic pleural effusion patterns (anechoic, complex nonseptate, complex septate, and homogeneously echogenic), an echogenic swirling pattern has been previously described, which was originally thought to be associated with malignant effusion. Two cases of pleural effusion with an echogenic swirling pattern are described below, illustrating that this sonographic finding can be seen in both exudative and transudative effusions.

Cardiovascular Imaging for the Primary Prevention of Atherosclerotic Cardiovascular Disease Events.

Traditional cardiovascular risk factors have well-known limitations for the accurate assessment of individual cardiovascular risk. Unlike risk factor-based scores which rely on probabilistic calculations derived from population-based studies, coronary artery calcium (CAC) scoring, and carotid ultrasound allow for the direct visualization and quantification of subclinical atherosclerosis with the potential for a more accurate, personalized risk assessment and treatment approach. Among strategies used to guide preventive management, CAC scoring has consistently and convincingly outperformed traditional risk factors for the prediction of adverse cardiovascular events.

Multimodality imaging of multivalvular endocarditis after transcatheter aortic valve replacement.

Transcatheter aortic valve replacement (TAVR) has emerged as an alternative to surgery for severe aortic stenosis in non-operable and high surgical risk patients. While endocarditis following TAVR is rare, the significant co-morbidities commonly found in this patient population can complicate evaluation and management. A case of TAVR endocarditis initially diagnosed by cardiac computed tomography angiography and confirmed with transesophageal echocardiogram is presented.

Analysis of the pan genome of Campylobacter jejuni isolates recovered from poultry by pulsed-field gel electrophoresis, multilocus sequence typing (MLST), and repetitive sequence polymerase chain reaction (rep-PCR) reveals different discriminatory capabilities.

Campylobacter jejuni is one of the leading bacterial causes of food-borne illness in the USA. Molecular typing methods are often used in food safety for identifying sources of infection and pathways of transmission. Moreover, the identification of genetically related isolates (i.

Campylobacter jejuni strains compete for colonization in broiler chicks.

Campylobacter jejuni isolates possess multiple adhesive proteins termed adhesins, which promote the organism's attachment to epithelial cells. Based on the proposal that one or more adhesins are shared among C. jejuni isolates, we hypothesized that C.
