Objectives: The aim of the present study was to determine clinical features of Aerococcus infections and the significance of the Aerococcus species isolated from any clinical samples. Methods: Electronic records of all cultures yielding Aerococcus species from 2002 to 2012 were obtained from three tertiary care hospitals. We performed an…
Objective: To evaluate the clinical relevance and impact of an emerging bacterial pathogen, Staphylococcus lugdunensis, in a large teaching hospital. Methods: Three-year retrospective microbiological and clinical review of all S. lugdunensis isolates from a single medical center. Results: Seventy-seven isolates were identified; 70 had complete data. Soft tissue, bone, joint,…
Fungal infections of the heart are increasingly described especially in immunocompromised patients. Cardiac involvement can present with myocarditis, pericarditis or endocarditis. Cryptococcal endocarditis is extremely rare, with only four reported cases in the literature. The prognosis, natural history and the optimal management for cryptococcal endocarditis are not well described because…
A 19-year-old male patient was diagnosed with S. sanguinis brain abscess of unknown etiopathology as a complication of subclinical endocarditis. While viridans streptococci are implicated in dental seeding to the heart, S. sanguinis brain abscesses are rare. Six previous cases of S. sanguinis brain abscess in the literature reported dental…
Abstract:A case of Fusobacterium nucleatum endocarditis in an 80-year-old man is reported. The patient presented with a headache and nonspecific musculoskeletal symptoms and was misdiagnosed as having polymyalgia rheumatica. The diagnosis of bacterial endocarditis was delayed because of an insidious presentation, typical in infections with low virulence micro-organisms. The musculoskeletal…
Abstract:We report a case of native valve and pacemaker endocarditis in a 78-year-old male with diabetes mellitus who died after cardiac surgery. At autopsy, tricuspid valve vegetations and lung abscesses containing thick, hyaline, septate, and branching hyphae were present. The culture identified Scedosporium apiospermum, an infrequent cause of opportunistic infections…
A 90-year-old man was diagnosed with monoarticular arthritis due to pseudogout and Abiotrophia defectiva infection. A. defectiva is recognized as a cause of endocarditis, but is rarely described in septic arthritis. To our knowledge, this is one of the few case reports of septic arthritis due to this organism, and…
Prosthetic valve endocarditis is a significant infection. It is often serious, and may result in a complicated course leading to valvular malfunction. We present the case of a 50-year-old male with an aortic Medtronic Hall valve, who presented with loss of his normal metallic click. A transthoracic echocardiogram confirmed the…
