Although cerebral angiography should be approached with caution in the diagnosis of inflammatory cerebro-vascular disease there are some characteristic angiographic findings which may be helpful for classification and differential diagnosis. The proximal cerebral arteries are favourably affected by basal meningitis and thrombangiitis obliterans with resulting stenoses and occlusions. Whereas those inflammations originating from neighbouring skull structures mostly involve the intracavernous parts of the carotid artery, the tuberculous and mycotic arteritis prefer the supraclinoid carotid siphon. Peripheral vascular changes are found in luetic endangiitis, necrotizing and toxic angiitis and in collagenoses. Simultaneous involvement of the temporal arteries is of great diagnostic importance demonstrating the systemic character of the inflammatory process; in Horton's arteritis it can be a pathognomonic finding. Infectious endocarditis, some mycoses and malaria may lead to embolic occlusion of cerebral vessels. Mycotic aneurysms mostly have a broad base or a fusiform shape and do not prefer the localizations of congenital aneurysms. Angiographically, abscesses, tuberculomas and viral encephalitis may result in circumscribed hypervascularized areas. The characteristic angiographic findings are exemplified and discussed on the basis of 8 cases of inflammatory cerebro-vascular disease (tuberculosis, pneumococcal and unspecific bacterial meningitis, syphilis, mycosis, Takayasu-syndrome, panarteritis nodosa, temporal arteritis).

A 10-year analysis of 113 cases of staphylococcal endocarditis seen in two Washington, D.C., hospitals is presented. 96% of the cases occurred in parenteral drug addicts, but 4% complicated septicemia from known foci of infection. Coagulase positive staphylococcus was responsible for 97% of the infection, and the rest were caused by coagulase negative staphyloccus. Except in four patients with previously known cardiac murmurs, infection occurred on normal valves in these patients. Infection was isolated to the tricuspid valve in 71%, to the mitral valve in 6% and to the aortic valve in 3.5% of our cases; and more than one cardiac valve was affected in the remaining patients. All patients were treated with antibiotics based on bacterial sensitivity testing. The mortality from isolated tricuspid endocarditis was 5%, from isolated mitral endocarditis 33%, and from isolated aortic valve endocarditis 100%. The overall mortality was 18%. The better prognosis documented for acute tricuspid endocarditis is related to the much less severe haemodynamic consequences of acute tricuspid regurgitation, and the probably milder consequences of septic pulmonary embolism compared with coronary or cerebral embolism.

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.

Insertion of a polyethylene catheter into the left ventricle of the heart was used for regular establishment of sterile endocarditis, and bacterial endocarditis was established by injection of approximately 10(8) Streptococcus faecalis into the blood stream at the same time as removal of the catheter which had been in place for 3 days. 100 out of 102 rabbits died spontaneously of bacterial endocarditis. Evidence is produced that the host-parasite interaction is influenced by the proteolytic property of S. faecalis in this experimental model. Two distinct types of clinical course are described: 1) A predominantly acute and damaging illness, characterized by a high level of bacteraemia, small amounts of soft, friable vegetations in the left side of the heart, high frequency of kidney infarcts and shorter survival time in rabbits infected with proteolytic strains. 2) A relatively subacute illness, characterized by a lower level of bacteraemia, large, hard, non-friable vegetations on the aortic valves, less pronounced destructive changes in the substance of valve leaflets, relatively lower frequency of kidney infarcts and longer survival time in rabbits infected with non-proteolytic strains. The results suggest that proteolytic strains of S. faecalis cause partial dissolution of the vegetations resulting in a more severe clinical picture.

22 cases of aortic valvular insufficiency treated by prosthesis and in which the acinetic areas of the left ventricle were eliminated at the same time are reported. Only one postoperative death (ventricular fibrillation) was encountered; one after 1 year (emboly as a result of endocarditis) and one as a result of an unknown cause. Emphasis is laid upon the frequency of this associated complication, its seriously negative incidence on ventricular haemodynamics, the need for surgical treatment, and its favourable immediate and long-term results.

Based on the observation that adenomatous carcinomas are frequently associated with tumor endocarditis, whereas undifferentiated tumors are not, autopsy material of tumor cases was examined for differences in the immune response with regard to the histological typing of the tumors. In the former group signs of stimulated cellular and humoral immune mechanisms were markedly stronger developed than in the latter group. From these findings it is suggested that tumor endocarditis represents an immune complex disease.

In a retrospective analysis of bacterial endocarditis, 84 of 192 cases (44%) were found to have musculoskeletal manifestations of one or more types. Common manifestations were arthralgias (32 cases), arthritis (26 cases), low back pain (24 cases), diffuse myalgia (16 cases), and myalgias localized to the thigh or calf (11 cases). The joint manifestations typically were monarticular or oligoarticular, and the myalgias were commonly unilateral. No association was found between the pattern of rheumatic symptoms and other clinical manifestations, laboratory tests, or causative bacterial organisms. In 52 patients (27%), musculoskeletal complaints were the first or among the first symptoms of bacterial endocarditis. The frequency and character of these manifestations and their tendency to occur early in the course of the disease indicate that they are an important feature of endocarditis which, if not recognized, may cause a delay in the diagnosis by mimicking a rheumatic disease.

The records of 180 patients out of 247 with bacterial endocarditis were examined. 50 patients had rheumatic manifestations. In 10 there was arthritis of 2-12 weeks' duration before diagnosis; 19 had myalgia/arthralgia; 17 had back or neck pain; 14 had demonstrable arthritis; and 2 tenosynovitis of the foot. Of the 14 patients with arthritis, 8 had monarticular arthritis and 6 polyarticular. All but one patient had a raised erythrocyte sedimentation rate, and in one patient rheumatoid factor was positive. The rheumatic features responded when the endocarditis was treated. Some of the symptoms undoubtedly resulted from the infection and fever of the endocarditis, and emboli may have caused the transient aches but there was no evidence that they caused the synovitis in the patients with arthritis. The rheumatic manifestations of bacterial endocarditis can mimic other rheumatic diseases and disguise the underlying disease.

Group B beta-hemolytic Streptococcus, S agalactiae, is an uncommon cause of endocarditis in adults. We present the clinical, laboratory, and postmortem findings of an adult patient with group B streptococcal endocarditis and major arterial emboli. What to our knowledge are previously unreported features are purulent pericarditis and myocardial abscesses. Twenty-five cases of endocarditis caused by group B Streptococcus that are reported in the literature are reviewed.

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.
