Infective endocarditis remains an important and life-threatening infection despite improvements in diagnosis and management. There is currently a greater role for nosocomial acquisition of organisms and immunosuppression in the pathogenesis of this disease and emergence of a broader spectrum of infective organisms including those not commonly isolated from the mouth such as staphylococci. We report a case of infective endocarditis caused by Staphylococcus aureus in which the patient developed disseminated intravascular coagulation and multiple septic infarcts resulting in a frontal lobe brain abscess. Multiple dental extractions were complicated by delayed postextraction hemorrhage and the immediate cause of death was abdominal hemorrhage. The dental management in infective endocarditis should be planned in consultation with the attending physician, and should take into account both the causative organism and the presence of complications. When the oral cavity cannot be proven as the bacterial source for infective endocarditis, the immediate dental management should be directed toward improving the patient's oral hygiene and providing pain relief. Definitive long-term treatment, including any extractions, is ideally delayed until the patient has fully recovered from the infective endocarditis and its attendant complications.

An 80-year-old Japanese man had a fall presented with a 3-week history of right lumbago exacerbated by body movement as well as a 1-week history of anomalous behavior and appetite loss. He visited our hospital complaining of difficulty in standing up. He had a history of mitral prolapse due to an unknown rupture of the chordae tendineae 3 years earlier, which resulted in moderate mitral valve regurgitation and atrial fibrillation. Upon visiting the hospital, he had petechial hemorrhage and jaundice of the conjunctiva, a systolic murmur (Levine II/VI) at the apex and 4th interspace of the left sternal border, and a positive right straight leg raising test result. Moderate bilirubinemia and disseminated intravascular coagulation which were considered to have been produced secondarily were observed. Infective endocarditis was suspected, and 3 sets of blood culture were extracted. The patient was admitted on the same day. Blood cultures were positive for Streptococcus gallolyticus subsp. gallolyticus (6/6) on the following day. Transesophagela echocardiography was carried out on the same day, and vegetation with a diameter of 4mm was observed in the anterior mitral leaflet; the patient was subsequently diagnosed as having infective endocarditis. Colonic endoscopy was performed after hospitalization. Twelve colonic adenomata were found, and endoscopic mucosal resection was performed on one polyp. The bacterium found in the culture was classified as Streptococcus bovis type I, which causes infective endocarditis and bacteremia. Furthermore, this bacteria is a relatively rare causative organism of infective endocarditis. Tolerance to macrolide and tetracycline are reported in the literature. Moreover, the cell wall of this bacterium may have low pathogenicity as well as cause chronic inflammation in the large intestine mucous membrane, colonic polyps, and colorectal cancer. Several colonic adenomata and a partial shift to a malignant pathology were observed in this case. When this bacterium is detected, searching for a pathological change in the large intestine is believed to be indispensable.

The use of cardiac pacemakers is increasing worldwide. Infective endocarditis from a pacemaker lead is a rare, but one of the most severe complications of pacemaker insertion. The diagnosis of pacemaker-related infective endocarditis is usually delayed due to unspecific clinical signs and symptoms at presentation compared to native valve infective endocarditis. Several factors can increase the risk of cardiac pacemaker-related infective endocarditis including cachexia, malignancy, diabetes mellitus, immunosuppression and corticosteroid treatment. This case report is about a 70-year-old diabetic male who presented to the emergency department with disseminated intravascular coagulation (DIC), cardiac and liver failure. He was diagnosed with pacemaker infective endocarditis, which was ultimately fatal.

BACKGROUND Infective endocarditis is prevalent worldwide and the modified Duke criteria have been used universally to diagnose this condition. However, making the correct diagnosis is rather difficult because the clinical presentation and findings of blood tests are non-specific. CASE REPORT A 70-year-old female complaining of dyspnea for 5 days with acute mitral regurgitation was transferred to our hospital. She had acute heart and respiratory failure and disseminated intravascular coagulation. Although infective endocarditis was suspected, repeated blood cultures and transesophageal echocardiography could not reveal any findings of infective endocarditis. Because the etiology of her condition was not determined by various examinations, mitral annuloplasty was required to treat her mitral regurgitation, and was performed for definitive diagnosis and treatment revealing the presence of vegetation on the mitral valve. Enterococcus faecalis was detected by cultures of the mitral valve and blood after the surgery. CONCLUSIONS It can be very difficult to diagnose infective endocarditis correctly, especially when a case fails to fulfill the modified Duke criteria. In such a case, only cardiac surgery might enable us to make an accurate diagnosis and save a patient's life.
