Dental treatment commenced without antibiotic cover. Patients need to be informed regarding their cardiac condition and infective endocarditis, and how this may affect dental treatment. [5] Discussion of pros & cons of antibiotic prophylaxis, why it is not generally advocated; Significance of adequate oral hygiene
Updated (2023) Modified Duke Criteria for Infective Endocarditis: Infective endocarditis (IE) is a life-threatening condition and the Duke criteria (established in 1994 and revised in 2000) has been fundamental for the diagnosis of the disease. However, the landscape of micro-biology, diagnostics, epidemiology, and treatment for lE has evolved ...
There are many circumstances during dental treatment where antibiotics are prescribed by dentists to prevent further infection (e.g. post-operative infection). The most common antibiotic prescribed by dental practitioners is penicillin in the form of amoxicillin, however many patients are hypersensitive to this particular antibiotic.
S. sanguinis may gain entrance to the bloodstream when opportunity presents (dental cleanings and surgeries) and colonize the heart valves, particularly the mitral and aortic valves, where it is the most common cause of subacute bacterial endocarditis. For this reason, oral surgeons often prescribe a short course of antibiotics to be taken a ...
Other strains of streptococci can cause subacute endocarditis as well. These include streptococcus intermedius, which can cause acute or subacute infection (about 15% of cases pertaining to infective endocarditis). [7] Enterococci from urinary tract infections and coagulase negative staphylococci can also be causative agents. [5]
Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Streptococcus gordonii is a Gram-positive bacterium included among some of the initial colonizers of the periodontal environment. [1] The organism, along with related oral streptococci, has a high affinity for molecules in the salivary pellicle (or coating) on tooth surfaces.
Another form of sterile endocarditis is termed Libman–Sacks endocarditis; this form occurs more often in patients with lupus erythematosus and is thought to be due to the deposition of immune complexes. [2] Like NBTE, Libman-Sacks endocarditis involves small vegetations, while infective endocarditis is composed of large vegetations. [2]
