Endogenous endophthalmitis due to Actinobacillus actinomycetemcomitans is an unusual disease with serious sequelae. Of the 4 cases published in the literature only 1 recovered useful vision after treatment. This study reports on 1 additional patient and expands on the previously described brief ophthalmology case report of another patient with marked visual impairment at presentation and good visual recovery after treatment. Of the 5 patients described, 4 had pre-existing heart abnormalities, 3 had permanent pacemakers and 2 had periodontal disease. Definite endocarditis by Duke criteria was present in 3 patients. Endocarditis should be ruled out in every patient with A. actinomycetemcomitans endophthalmitis, even in the absence of systemic complaints and prior penicillin prophylaxis. Eye specimen cultures should be incubated for 10 d. A thorough dental examination should be done in each patient and any periodontal disease should be promptly treated.

In a retrospective analysis of 128 cases of Candida bloodstream infections in a London teaching hospital between 1995 and 2001, the incidence of candidaemia increased from 0.2/1000 admissions in 1995 to 0.5 and 0.4/1000 admissions in 2000 and 2001, respectively. Risk factors for candidaemia included the presence of intravascular (IV) lines (88%), admission to intensive care (51%), parenteral nutrition (35%), multiple antibiotics (74%), corticosteroid therapy (12%), cancer chemotherapy (11%), renal transplantation (5%) and neutropenia (3%). The sources of infection were IV lines (77%), the urinary tract (7%) and the gastrointestinal tract (7%). Serious infective complications (endocarditis, endophthalmitis or brain abscess) were noted in 6% of cases. The most frequently isolated species were Candida albicans (64%), C. glabrata (20%), C. tropicalis (9%) and C. parapsilosis (5%). The overall fluconazole-resistance rate of Candida spp. was 7% (MIC > or = 64 mg l-1). All the C. albicans isolates were sensitive to fluconazole (MIC < or = 8 mg l-1) whereas 20% of non-C. albicans isolates (27% of C. glabrata and 14%C. tropicalis) were resistant. The mortality rate (35%) was lower than in other reports and may be due to the early recognition of candidaemia and the prompt removal of IV lines together with the initiation of appropriate antifungal therapy. Regular surveillance of local Candida species, resistance profiles and risk factors is important in order to identify patients at risk and to develop empirical treatment protocols to reduce the incidence and mortality of candidaemia.

Bacterial endocarditis due to Pseudomonas aeruginosa arising from arteriovenous (AV) fistula and graft infection is unusual. We report an uncommon case of a 55-year-old woman housewife with chronic glomerulonephritis who had received hemodialysis (HD) for 5 years. She was admitted due to frequent episodes of AV fistula and graft infections in the past 5 years. She was admitted to our hospital because of a fever of unknown origin. During hospitalization, cardiac sonography and transesophageal echocardiography (TEE) confirmed a vegetation over the mitral valve. Blood culture yielded Pseudomonas aeruginosa. Endophthalmitis of the right eye was diagnosed by funduscopy because of painful redness of the right eye with exudative discharge. The patient was treated with ceftazidime for 9 weeks. Since then, she has been well, without any sequale after 1 year of following up. Physicians should be aware of the possibility of infective endocarditis in an uremic patient who suffers from fever of unknown origin. Early diagnosis with an adequate tool such as TEE and appropriate treatment will lead to an excellent prognosis.

We report a case of endocarditis due to Arthrobacter woluwensis and review the published reports of Arthrobacter species isolated from human clinical samples. A 39-year-old injection drug user presented with fever and a new heart murmur. A. woluwensis was isolated from blood cultures, and a diagnosis of subacute infective endocarditis of the native mitral valve was made. The patient was successfully treated with a 6-week course of intravenous teicoplanin. From our review of the literature, we were able to retrieve data on 41 cases of Arthrobacter species isolated from human clinical samples. However, Arthrobacter species was documented as a cause of human disease on only 5 other occasions (2 cases of bacteremia, 1 case of postoperative endophthalmitis, 1 case of a Whipple disease-like syndrome, and 1 case of phlebitis). Because of the difficulty of identifying Arthrobacter strains by conventional biochemical assays, it is likely that infections with these coryneform bacteria are underreported.

Over the last few decades, the incidence of invasive candidal infections in neonatal intensive care units has increased dramatically. Various complications, such as arthritis, endocarditis, meningitis, and endophthalmitis, have been reviewed. We present the case of a premature infant with systemic candidemia. Arthritis was discovered 6 months after completion of amphotericin B therapy, and was successfully treated with oral fluconazole for 6 weeks. We conclude that long-term follow-up is particularly important in patients with treated candidemia. To prevent complications, prolonged treatment with high-dose amphotericin B is suggested for systemic fungal infection, and oral fluconazole is an effective alternative for candidal arthritis.

Haemophilus aphrophilus, an oral fastidious Gram-negative commensal with low pathogenicity, is a member of the HACEK group (H. aphrophilus, H. paraphrophilus, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella spp.), and a rare cause of human infections. We reviewed the characteristics of 8 cases of H. aphrophilus infections diagnosed in our hospital from 1990-2003, and an additional 20 cases identified from the MEDLINE database, from 1990 to 2003. Their mean age was 47.4 years (range, 7-73 years), and 21 cases (75%) were male. The major manifestation was bone and joint infections (9 cases, 32%), including osteomyelitis, discitis, epidural abscess, spondylodiscitis, septic arthritis and prevertebral infection. Seven cases (25%) presented with infective endocarditis, involving native valves, and one underwent valvular replacement. Of note, 3 cases (10%) had ophthalmic infections (endophthalmitis in 2 cases and canaliculitis in 1), and 2 of them had previous ophthalmic procedures. Other manifestations included bacteremia, meningitis, brain abscess, cervical lymphadenitis, facial cellulitis, empyema, and purulent pericarditis and tamponade. All patients except 1 survived. Recent dental procedure was recalled by 11 cases (39%), and may be a predisposing factor for invasive H. aphrophilus infection. Appropriate antimicrobial therapy, such as a beta-lactam/beta-lactamase inhibitor, ceftriaxone or cefotaxime or a fluoroquinolone, can lead to a favorable clinical outcome.

A recent outbreak of Streptococcus suis infection associated with the slaughter, preparation or consumption of pigs in Sichuan, China has led to concerns that similar outbreaks could occur in other Asian countries. Although the pig farming industry is flourishing in Taiwan, reports of S. suis infection remain rare. We report 2 cases of S. suis meningitis successfully treated with ceftriaxone and penicillin. Previous reports of S. suis infection from the English literature are reviewed and the clinical data of cases reported in Asian and European countries are summarized. In Europe, there was good correlation between clinical disease and porcine contact, while few cases in Asia reported this association. Meningitis remained the most common presentation of infection in both areas (84.6% and 75.2%, respectively), followed by sepsis (15.4% and 18.6%, respectively), which had a higher mortality rate, particularly for splenectomized patients. Other clinical presentations included enteritis, arthritis, endocarditis, pneumonia, spondylodiscitis, endophthalmitis, uveitis and peritonitis. Deafness was a distinct sequelae (50.5% in Europe and 51.9% in Asia) after recovery from S. suis infection, especially in patients with meningitis. Not all commercial identification systems for streptococci could offer adequate speciation for S. suis. When viridans group streptococci are isolated from patients with meningitis and sepsis, prompt and correct identification of isolates to the species level should be performed, especially in areas with a high prevalence of S. suis diseases.

Candida spp. are responsible for most of the fungal infections in humans. Available since 1990, fluconazole is well established as a leading drug in the setting of prevention and treatment of mucosal and invasive candidiasis. Fluconazole displays predictable pharmacokinetics and an excellent tolerance profile in all groups, including the elderly and children. Fluconazole is a fungistatic drug against yeasts and lacks activity against moulds. Candida krusei is intrinsically resistant to fluconazole, and other species, notably Candida glabrata, often manifest reduced susceptibility. Emergence of azole-resistant strains as well as discovery of new antifungal drugs (new triazoles and echinocandins) have raised important questions about its use as a first line drug. The aim of this review is to summarize the main available data on the position of fluconazole in the prophylaxis or curative treatment of invasive Candida spp. infections. Fluconazole is still a major drug for antifungal prophylaxis in the setting of transplantation (solid organ and bone marrow), intensive care unit, and in neutropenic patients. Prophylactic fluconazole still has a place in HIV-positive patients in viro-immunological failure with recurrent mucosal candidiasis. Fluconazole can be used in adult neutropenic patients with systemic candidiasis, as long as the species identified is a priori susceptible. Among non-neutropenic patients with candidaemia fluconazole is one of the first line drugs for susceptible species. Cases reports and uncontrolled studies have also reported its efficacy in the setting of osteoarthritis, endophthalmitis, meningitis, endocarditis and peritonitis caused by Candida spp. among immunocompetent adults. In paediatrics, fluconazole is a well tolerated and major prophylactic drug for high-risk neonates, as well as an alternative treatment for neonatal candidiasis. Importantly 15 years after its introduction in the antifungal armamentarium, fluconazole is still a first line treatment option in several cases of invasive candidiasis. Its prophylactic use should however be limited to selected high-risk patients to limit the risk of emergence of azole-resistant strains.

We report a case of Streptococcus sanguis endocarditis in a 45-year-old male who presented with bilateral endophthalmitis and glomerulonephritis. The patient responded favorably to appropriate antimicrobial chemotherapy with resolution of endophthalmitis and nephritis. Some striking features of this case and a comparison with other reported cases of this uncommon presentation of infective endocarditis are discussed.

We report a case of a 51-year-old diabetic male who presented with a complaint of intermittent chills and fever that he had experienced for 10 days. No obvious respiratory tract, genitourinary tract, gastrointestinal tract, or skin lesions were observed. Blood culture data were positive for group B beta-streptococcus. Transthoracic and transesophageal echocardiography revealed vegetation in the anterior leaflet of the mitral valve. The patient was diagnosed with infective endocarditis (IE) and prescribed a parenteral antibiotic. Three days after admission, the patient complained of progressively blurred vision. Slit lamp examination found fine keratic precipitates and aqueous cells in the anterior chambers in both eyes, implying that the patient had uveitis. He was then prescribed a topical steroid for 4 months, and his vision improved gradually. This case is an important reminder that uveitis, not only endophthalmitis, can occur with IE. Treatment for one condition, if misapplied, may worsen the other.
