Mycotic aneurysm due to Yersinia enterocolitica.

Infections of the cardiovascular system, besides involving both natural and prosthetic heart valves, vascular grafts, and indwelling venous and arterial cannulas, may cause mycotic aneurysms. The latter frequently complicate endocarditis; however, they may occur as isolated phenomena. Enterobacteriaceae are uncommon etiologic agents in vascular infections; however, a patient is reported who presented initially with a bacteremia due to Yersinia enterocolitica biogroup 4 and despite antimicrobial therapy developed a mycotic aneurysm of the left internal carotid artery. Clinical manifestations, pathogenesis, and treatment of yersiniosis are reviewed.

Hereditary angioedema and coronary arteritis.

A 30-year-old white male with hereditary angioedema developed substernal chest pain with multiple arterial stenoses at coronary angiography. Histopathologic studies of the fibromembranous thickening removed from the left coronary artery at the time of the revascularization procedure revealed an inflammatory lesion compatible with an arteritis. The significance of this association in the spectrum of immunologically-mediated disorders in hereditary angioedema is discussed.

The bone scan in primary care: diagnostic pitfalls.

Skeletal scintigraphy (bone scanning) is a useful adjunct in the diagnosis of disease states, such as osteomyelitis, and in the evaluation of occult fractures. Certain conditions can alter the appearance of bone scans, such as age of the patient, prior use of antibiotics, concomitant diseases, and disruption of the vascular supply. Three patients whose clinical problems highlight diagnostic problems with bone scans are discussed.
