From 1973 to 1983 nine cases of Brucella melitensis infection were hospitalised at the Centre hospitalier universitaire vaudois (CHUV), Lausanne. In each case, the infection was acquired in a Mediterranean country (4 cases in Italy, 2 in Spain, 2 in Portugal and 1 in Greece). In 6 of the cases the disease was acquired by ingestion of dairy products and in 2 cases by direct animal contact. Despite classical initial symptomatology (fever, rigors, weakness), the time from first symptoms to diagnosis varied between 10 days and 5 months. This delay probably explains why 6 of 9 patients were admitted because of septic complications: orchi-epididymitis, arthritis, meningitis and endocarditis. With prolonged antibiotherapy, the evolution was favourable in all cases. The patient who presented with endocarditis required emergency aortic valve replacement. Culture of the valve showed the presence of 10(9) B. melitensis/g of tissue. Cure was achieved by the administration of streptomycin and tetracycline for 6 weeks, followed by cotrimoxazole for one year. These cases show that the diagnosis of Brucella infection is becoming rare in Switzerland. It is often not suspected, and prompt diagnosis is delayed until further complications occur. Serology and blood cultures should be done in every patient presenting with fever after a stay in endemic countries.

Bacterial endarteritis is rare and usually affects the abdominal aorta. A case of bacterial left subclavian arteritis complicated by mycotic aneurysm is presented. An early diagnosis of infective arteritis was made based on a history of fever, sweats, rigors, and a progressive macular rash, polyarthralgia splinter haemorrhage (limited to the left arm), and a loud left subclavian bruit on admission. A mycotic aneurysm was diagnosed by computed tomography and treated surgically. In cases of endarteritis the possibility of a mycotic aneurysm should be borne in mind even when there is no evidence of endocarditis.

Catheter-related bloodstream infections (CBIs) rank among the most frequent and potentially lethal nosocomial infections. Intravascular devices become contaminated on the outer surface during nonaseptic insertion or maintenance of the catheter exit site or endoluminally during hub manipulation. CBI is heralded by spiking fever, malaise and rigors and should be promptly diagnosed to prevent endocarditis and septic metastasis. In about two-thirds of the cases the offending organisms are coagulase-negative staphylococci; Staphylococcus aureus, gram-negative bacilli, and Candida sp. are responsible for one-third of these infections and carry a worse prognosis. Diagnosis of CBI relies on proper bacteriologic techniques, some of which can be performed in situ avoiding withdrawal of the device. Prevention strategies should aim at avoiding extra- and endoluminal contamination and should be based on three main pillars: maximal aseptic barriers at insertion, appropriate site maintenance, and junctional (hub) care and protection. Treatment includes catheter withdrawal and appropriate antibiotic coverage. For long-term cuffed catheters, local treatment with intraluminal administration of antibiotics is effective and can save a significant number of catheters, particularly those colonized by coagulase-negative staphylococci.

Improved understanding of the pharmacodynamics and toxicity of aminoglycoside antibiotics has resulted in the study of once-daily dosing regimens. Although studies have suggested a therapeutic advantage and possibly a decrease in toxicity with once-daily administration, these effects have been modest. The cost savings associated with once-daily aminoglycoside administration, however, makes this approach appealing. Although a syndrome of fever, tachycardia, hypotension, and rigors has been associated with once-daily dosing of gentamicin, this appears to have been the result of impurities in the antibiotic from a single offshore supplier. This syndrome has not been associated with other aminoglycoside antibiotics, and the FDA has now withdrawn its recommendation that once-daily aminoglycoside use be avoided. As with any medical regimen, the decision to use once-daily dosing of aminoglycoside agents must take into account special patient characteristics and the disease state being treated. Although once-daily dosing appears effective in limited studies in children, in individuals with neutropenia, and in individuals with cystic fibrosis, its role in gram-positive coccal endocarditis and in individuals with altered volumes of distribution remains uncertain. Further data are needed to clarify the role of once-daily dosing in these situations.

Piercing invades subcutaneous areas and has a high potential for infectious complications. The number of case reports of endocarditis associated with piercing is increasing. We studied a 25-year-old man with a pierced tongue, who arrived at Memorial Health University Medical Center with fever, chills, rigors, and shortness of breath of 6 days' duration and had an aortic valvuloplasty for correction of congenital aortic stenosis.

We report the successful treatment of Staphylococcus aureus endocarditis in a renal transplant recipient with preservation of his renal allograft. A 44-year-old man presented to the emergency room with sudden onset of fevers and rigors 7 weeks after renal transplantation. Infective endocarditis was diagnosed by Duke's Criteria (Durack et al. New criteria for the diagnosis of infective endocarditis. Am J Med 1994: 96: 200-209) with multiple positive blood cultures for S. aureus and a mitral valve vegetation on transesophageal echocardiogram. He was treated with intravenous antibiotics for 6 weeks with continuation of his immunosuppression. He has remained clinically stable for over 5 years. Although the treatment of S. aureus endocarditis in immunosuppressed transplant patients has traditionally resulted in loss of their allograft, prompt diagnosis and appropriate antibiotics with continued immunosuppressive therapy resulted in a successful outcome and allograft preservation in this case.

The authors present the case of an otherwise healthy retired male who presented with a history of fevers, rigors and right upper quadrant abdominal pain. Although haematological, biochemical and radiological investigations supported a diagnosis of acalculous cholecystitis, the underlying cause was not obviously apparent and the patient's clinical condition deteriorated rapidly over the course of a few hours despite appropriate medical treatment. Repeat clinical examination was consistent with acute pulmonary oedema in association with a new murmur throughout the whole of the cardiac cycle. Transthoracic echocardiography revealed the presence of severe aortic regurgitation, a presumptive diagnosis of infective endocarditis was made and medical therapy adjusted. Shortly after, the patient suffered a cardiac arrest and an attempt at resuscitation was unsuccessful. Postmortem examination revealed the presence of aortic valve cusp rupture secondary to bacterial endocarditis in addition to gallbladder appearances consistent with acute acalculous cholecystitis.

A 17-year-old male with a history of newly implanted mechanical valve at the aortic position, presented with fever, rigors, and painful cutaneous abscesses on his lower extremities and was suspected for infective endocarditis. Transthoracic echocardiography (TTE) showed a vegetation-like structure following the movement of the mechanical heart valve (MHV), which eventually proved to be a product of degassing microbubbles (MB).

A 24-year-old otherwise healthy man presented with a 3-week history of malaise, headache, fever and rigors after he was treated with oral clindamycin for left parotitis and Gemella haemolysans bacteraemia. He developed G. haemolysans infective endocarditis, septic emboli and heart failure due to progressive bivalvular disease. He underwent urgent mechanical aortic valve replacement and mitral valve repair, which required venovenous extracorporeal membrane oxygenation, to support severe respiratory failure. This is the first documented case of G. haemolysans infective endocarditis affecting native aortic and mitral valves in a healthy adult.
