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.

A case of staphylococcus epidermidis endocarditis associated with a right atrial thrombosis around a pacemaker electrode is presented. Stuce the antibiotic therapy had proved uneffective, the electrode had to be removed with cardiopulmonary bypass; the infection was subsequently eliminated. When a foreign body cannot be removed by closed techniques, open heart surgery with cardiopulmonary bypass may be necessary.

Between December 1982 and March 1990, 65 patients with active infective endocarditis underwent cardiac operations. Their mean age was 28.6 years (range 1 to 65 years). The most common infecting organisms were staphylococcus (33.8%), streptococcus (18.5%), and brucella (16.9%); 11 patients (16.9%) had cultures negative for infection. A rheumatic, native valve, most commonly the aortic, was involved in 40 patients, a prosthetic valve (with the mitral most common) in 18 patients, and in seven patients the infection involved a congenitally abnormal valve. Aortic root abscess developed in 21.5% of patients. In 30 patients operation was performed within 3 days of the start of intravenous antibiotic therapy, usually within 3 days of admission (group A); this resulted in fewer preoperative complications and a significantly lower postoperative complication rate than in those 35 patients who underwent operations more than 3 days after starting antibiotic therapy (group B). Preoperative embolic phenomena occurred in eight (12.3%) of the 31 patients who had large, mobile vegetations (2/16 [12.5%] in group A and 6/15 [40%] in group B). Overall there was no reinfection. No postoperative paravalvular leaks developed in group A. Nine patients died in the hospital (13.8%) (four in group A and five in group B); in all patients the infecting organism was staphylococcal or fungal. There was one late death. Early operation should always be considered in active infective endocarditis, especially when a prosthetic valve is involved or the infecting organism is staphylococcal or fungal. The disclosure of moderate to large vegetations by two-dimensional echocardiography is an indication for operation.

Twenty eight patients with native valve endocarditis (NVE) were subjected to this study. Thirteen patients underwent an operation at the chronic phase, and 15 patients at the active phase. One of the 13 patients at the chronic phase died of cardiac rupture due to myocardial infarction which had occurred preoperatively, and one of 10 patients at active phase without annular infection died of rupture of mycotic cerebral aneurysm early postoperatively. Among 5 patients at the active phase with annular infection, prosthetic valve endocarditis occurred in one patient 1.5 months after supraannular aortic valve replacement, and the second operation with a translocation technique was needed. This patient was lost from low output syndrome. Another patient in this group, who underwent a translocation technique because of mycotic annular abscess, died of intestinal infarction late postoperatively. The other 24 patients went a good postoperative course. Five patients with annular infection at the active phase had a shorter duration from the infectious onset to operation (20 days to 2 months, average 38 days), and the causative microorganisms were streptococcus faecalis, staphylococcus epidermidis and gram-negative coccus. One patient, who died of mycotic cerebral aneurysmal rupture, had candida albicans as a causative microorganism. For patients with NVE, an early aggressive operation is essential before infection extends to the annulus or to other vital organs, especially when these microorganisms are identified.

Localized bacterial skin infections are frequent. In furunculosis, a local treatment is usually sufficient. In case of frequent recurrence a possible staphylococcus aureus colonization should be looked for and eliminated. Erysipela is treated by systemic antibiotics in order to avoid complications such as streptococcal gangrena or parainfectious glomerulonephritis. Anaerobic cellulitis and gas gangrena are postoperative or posttraumatic infections of the soft tissues which require a combined surgical and antibiotic treatment. Systemic infections may be recognized by characteristic skin lesions. These skin lesions are the consequence of bacterial emboli, vasculitis, intravascular coagulation or toxins, respectively. Examples for such manifestations are lesions in endocarditis, purpura fulminans, ekthyma gangrenosum, disseminated candidemia and toxic shock syndrome.

A 60-year-old female with mitral stenosis developed prosthetic valve endocarditis due to methicillin resistant staphylococcus aureus septicemia 3 weeks after mitral valve replacement. In vitro test disclosed susceptibility to minocycline and clindamycin. Despite large amount of intravenous administration, progressive heart failure due to massive perivalvular leakage occurred as a consequence of persisting infection. An emergent operation revealed valve detachment of the posterior portion resulting from ring abscess formation. A mitral prosthesis with a Gore-Tex flange was implanted partially in the left atrium just above the mitral ring and sutured to the atrial wall. Postoperative relapse was not detected even after discontinuing antibiotics. Prosthetic valve endocarditis due to methicillin resistant staphylococcus aureus is highly resistant to antibiotic therapy and likely to develop valve ring abscess. Prompt surgical treatment is mandatory in this situation.

Thirty out of 287 patients (10.4%) admitted to hospital for infective endocarditis between December 1970 and January 1990 had neurological complications. Twenty-three patients had native valve infectious endocarditis and 7 had prosthetic valve endocarditis. The clinical features were characterized by the frequency of aortic valve involvement (23 out of 30) and other complications, especially cardiac failure (16 cases) and peripheral vascular manifestations (7 cases). The commonest organism was the staphylococcus (53% of identified organisms) but the number of negative blood cultures was high (50% of cases). The neurological complication was often the presenting symptom of the endocarditis (19 cases) but it occurred after bacteriological cure in 4 cases. The complications observed were cerebral ischemia (16 cases), cerebral haemorrhage (11 cases), coma (2 cases), and one peripheral neuropathy causing a Claude Bernard Horner syndrome. These complications presented with hemiplegia in 17 cases, a meningeal syndrome in 8 cases, a convulsion in 1 case, a Von Wallenberg syndrome in 1 case, and a Claude Bernard Horner syndrome in 1 case. Twelve patients had a transient or permanent neurological coma. Cerebral CT scan showed ischemic lesions in 7 cases and haemorrhagic lesions in 10 cases. Carotid angiography demonstrated mycotic aneurysms in 6 patients. Twelve patients died: the cause of death was neurological coma (7 cases), low cardiac output (4 cases) and haemorrhagic shock (1 case). Four patients underwent neurosurgery: 3 for clipping a mycotic aneurysm and 1 for drainage of an intracerebral haematoma. Poor prognostic factors were: coma, cardiac failure, cardiac valve prosthesis and, above all, the extent and multiplicity of the neurological lesions. The authors propose the following measures to improve the prognosis: early surgery in cases of large and/or mobile vegetations especially when the infecting organism is a staphylococcus and when a systemic embolism has occurred; routine CT scanning and/or digitised cerebral angiography in all patients with infective endocarditis to detect surgically accessible mycotic aneurysms.

Ten cases of right-sided infective endocarditis (IE) were recorded in a retrospective study over a 5 year period (1984-88). In 8 cases, IE complicated known congenital heart disease. One patient was followed up for rhumatic valvular disease and in the remaining case, IE seemed to have occurred on a normal valve. The inclusion criteria were based on the clinical signs: prolonged pyrexia, the finding of a new murmur or a change on cardiac auscultation, and eventually, the occurrence of a complication (7 cases). The commonest complications were right ventricular failure and pulmonary embolism. A portal of entry was found in 5 cases: dental infection in 3 cases, osteomyelitis in 1 case and an abscess on the right leg in 1 case. Blood cultures were positive in 5 cases and grew a staphylococcus aureus on each occasion. Two-dimensional echocardiography showed vegetations in 9 cases. The short-term outcome was satisfactory. There were no fatalities and 5 patients underwent surgery.

Five cases of neonatal infective endocarditis are reported. The mitral, tricuspid and pulmonary valves were involved either alone or in association. The predisposing factors were multiple: umbilical catheter, respiratory distress with assisted ventilation, septicemia, osteoarthritis or gastroenteritis. Only one child had a minor cardiac malformation. The causal organism was a staphylococcus aureus in all cases. All children had disseminated intravascular coagulation and a cardiac murmur. The diagnosis was confirmed by echocardiographic demonstration of bacterial vegetations. Three of the 5 children died despite long-term antibiotic therapy. In one case, a vegetation embolised to the pulmonary artery. In the two cured neonates the vegetations disappeared. These cases illustrate the value of echocardiography which should be performed in all neonates with septicemia or disseminated intravascular coagulation, especially when there is an associated cardiac murmur.

The authors have evaluated the efficacy and tolerance of teicoplanin against Gram-positive infections in 8 patients (four with endocarditis, one with cholangitis, one with purulent arthritis, one with gathered fistula and one with general pyoderma), arose both in the immunocompetent and immunodepressed subjects. All patients received IM teicoplanin at a dosage of 200-400 mg/die, according to the severity of the infectious process. Teicoplanin proved to be an effective and well-tolerated drug in the treatment of staphylococcus infections, both for immunocompetent and with serious deficit of the immune system subjects.
