Nine patients examined by arteriography were shown to have mycotic aneurysms involving the thoracic aorta, subclavian artery, renal artery, middle cerebral artery, hepatic artery, and splenic artery. Patients presented with sepsis, chest pain, mediastinal mass, headache, hypertension, and intraperitoneal bleeding. Etiologic factors included endocarditis, septicemia, drug abuse, and poorly controlled soft-tissue infection. Most mycotic aneurysms were virulent processes with rapid progression and only three of the nine patients (33%) survived. Since mycotic aneurysms may be associated with rapid progression and poor prognosis, early recognition is mandatory.

This case report describes a 20-year-old woman who developed acute group B streptococcal endocarditis after a saline-induced abortion. She was admitted 2 weeks after an uncomplicated saline-induced abortion for a 16-week pregnancy with a 1-week history of fever, headaches, dizziness, and shortness of breath. The patient showed poor response to antibiotic therapies (initially to nafcillin and gentamicin and then to aqueous penicillin G). 6 to 6 blood cultures after hospital admission showed group B streptococcus which was penicillin sensitive by tetracycline resistant. On Day 3 of admission, a pericardial friction rub was noted and repeat chest x-rays showed marked enlargement of the cardiac shadow. Surgery was performed, and the mitral valve posterior leaflet was necrotic, and a mitral valve prosthesis was placed and an aortic embolectomy was performed. Postoperatively, she was treated with an additional 6-week course of intravenous penicillin, and subsequently, she has remained asymptomatic after 6 months. An addendum to this report, which was only the 2nd such report of endocarditis after saline abortion, describes another case of group B streptococcal endocarditis in a drug abuser after a saline-induced abortion. She required tricuspid valvulectomy and is slowly improving postoperatively.

Bacterial endocarditis caused by Actinobacillus actinomycetemcomitans is a rare disease. A 48-year-old man who had a Starr-Edwards aortic valve prosthesis inserted in 1972 was admitted for evaluation of confusion, headaches, anorexia, weight loss, diarrhea and weakness. Six blood cultures yielded gram-negative organisms which were subsequently identified as A. actinomycetemcomitans. Treatment with ampicillin and gentamicin resulted in cure which has been maintained after an observation period of eleven months. This represents the second report of A. actinomycetemcomitans endocarditis in a patient with a prosthetic valve.

There is a strong link between antiphospholipid antibodies and stroke. Retrospective studies indicate that these patients are generally young, often have had prior thrombotic events including stroke, frequently complain of headaches, and often experience amaurosis fugax. Cardiac valvular lesions, particularly involving the mitral valve, are frequently found. The limited pathological studies show a noninflammatory thrombotic occlusion of both large and small cerebral vessels and a "thrombotic endocarditis." The underlying pathogenesis involves an immune-mediated prothrombotic state.

A 55-year-old man with a mild fever and sweating developed severe headache for the days before admission. Cerebral computed tomography and selected cerebral angiography on the day of admission revealed subarachnoid hemorrhage due to rupture of an aneurysm of a distal branch of the left middle cerebral artery. Detection of vegetation on the aortic valve by two dimensional echocardiography confirmed the diagnosis of infective endocarditis with a ruptured mycotic cerebral aneurysm. Because of rapid growth of the vegetation on the aortic valve and progression of heart failure despite antibiotic therapy, emergency cardiac surgery was performed. To prevent re-rupture of the aneurysm, the aortic valve was replaced with a bioprosthetic valve, and no anticoagulant was administered postoperatively. Repeated cerebral angiography revealed that the aneurysm was becoming progressively smaller during the next 9 months. No cerebrovascular accident occurred postoperatively. We believe that it is safe to treat a ruptured mycotic cerebral aneurysm without involvement of a hematoma mass in the brain conservatively, and that use of a bioprosthetic valve, if valve replacement is mandatory, and avoidance of anticoagulant therapy during the postoperative period are advisable in the treatment of a patient with infective endocarditis and a ruptured cerebral mycotic aneurysm.

We have described a 28-year-old male sheepfarmer who had fever, headache, chills, malaise, and aortic insufficiency. Echocardiography revealed a tricuspid aortic valve with a large vegetation on the right cusp, an enlarged left ventricle, and diastolic flutter of the mitral valve. Repeated blood cultures were negative. Seroconversion of IgG and IgM to Rickettsia typhi was found on the 13th day of hospitalization. The patient was treated with tetracycline for 1 year and remained afebrile and free of symptoms for 9 months, when he was lost to follow-up. IgM and IgG fluorescent antibodies to R typhi remained positive during 8 months of the follow-up period. We believe this to be the second reported case of endocarditis due to R typhi and the first not treated surgically.

A case of intracranial mycotic aneurysm due to culture-negative infective endocarditis involving a patient with hypertrophic cardiomyopathy is reported. The patient, a 22-year-old woman with no history of known prior disease, had fever, headache and focal neurologic symptoms 3 days before admission. An echocardiogram performed after admission disclosed an obstructive hypertrophic cardiomyopathy and a gross vegetation on septal leaflet of mitral valve. Cerebral angiography revealed a mycotic aneurysm involving a peripheral branch of the left middle cerebral artery. Causal agent was not identified, and empiric treatment with penicillin G and streptomycin achieved medical cure and disappearance of the aneurysm 2 weeks later. Four months after endocarditis had been cured, the patient was electively operated because of progression of mitral regurgitation. Six months later, she is asymptomatic.

Neurological complications of Coxiella burnetii infection (Q fever) are rare, although the occurrence of headache, paresthesias, and transient focal deficits has been reported. We report the case of a patient with a relapsing demyelinating polyradiculoneuritis as an aftermath of C. burnetti endocarditis and pneumonia.

Four patients with fungal endocarditis after open-heart surgery were confirmed microbiologically. Two of them died, and the other 2 were treated with intravenous administration of miconazole. Clinical symptoms of the disease were similar to those of bacterial endocarditis, but headache and sweating were more predominant. This complication was likely to be found and treated with effective anti-fungi drugs. We suggest that reoperation is the only possible way to cure those with residual shunt or vegetation, and that prevention of postoperative fungal endocarditis is of great importance because of its refractoriness. Measures of preventing fungal endocarditis after open-heart surgery are discussed.

Neurologic syndromes often complicate the management of infective endocarditis (IE). We retrospectively reviewed 166 episodes of native valve endocarditis to assess the occurrence and implications of nonfocal encephalopathy, meningitis, salient headache, back pain, and brain abscess. Neurologic complications occurred in 35% (58/166) of patients: 41% (54/133) of mitral or aortic valve IE and 12% (4/33) of tricuspid valve IE. Of 133 cases of mitral or aortic valve IE, encephalopathy occurred in 14%, meningitis in 5%, and salient headache in 3%. All neurologic complications occurred more often with Staphylococcus aureus infection (67%) than with viridans streptococci (22%), including encephalopathy (22% versus 7%), meningitis (17% versus 0%), stroke (39% versus 16%), and death (39% versus 9%). Encephalopathy was associated with virulent organisms, increased patient age, and uncontrolled infection. Clinical, radiologic, and neuropathologic data all suggest that infective microemboli are often etiologic in IE-related encephalopathy. There were no macroscopic brain abscesses clinically identified. Meningitis occurred only with virulent organisms. While many clinical aspects of IE have changed in recent years, the frequency and gravity of neurologic complications have not.
