Fungal valvular endocarditis is an unusual cause of endocarditis, yet very important because of its historically poor prognosis. We report two fatal cases of fungal valvular endocarditis following cardiovascular surgery, presenting as femoral artery embolism. Aspergillus terreus and A. flavus were the causative agents of endocarditis in the two patients. Diagnosis was established very early by culture of the emboli and was confirmed later by isolation of the same Aspergillus species from the resected valve tissue.

Fungal infections caused by Fusarium in the immunocompromised host are highly resistant to all antifungal agents. Fusarium endocarditis is a rare and usually fatal disease. We report an immunocompromised child who survived Fusarium solani endocarditis despite the in vitro resistance of the organism to all available antifungal agents.

A retrospective review of a five year period (1994-1998) revealed that opportunistic mycoses caused by ubiquitous fungal pathogens are a serious problem in the immunocompromised patient population of Kuwait. Patients with renal transplantation and diabetes mellitus were most susceptible to aspergillosis, cryptococcosis, and zygomycosis, whereas patients with candidemia/hematogenous candidiasis had multiple risk factors. Basidiobolomycosis of the rectum in a Bangladeshi male, cryptococcosis due to Cryptococcus neoformans var. gatti in an AIDS patient,fungal peritonitis due to Absidia corymbifera in a patient on peritoneal dialysis, and endocarditis due to Aspergillus terreus detected by direct microscopic examination and culture of the blood clot are some of the notable cases diagnosed during the period under review. The predominance of Candida species other than C. albicans as bloodstream pathogens is another noteworthy observation. Although outbreaks of C. parapsilosis candidemia in neonatal intensive care units contributed significantly to this shift in favour of non-albicans Candida species, a surveillance strategy comprising of molecular, epidemiologic and antifungal susceptibility studies is warranted. With the proposed expansion of organ and bone marrow transplantation facilities in Kuwait, the incidence of opportunistic fungal infections is likely to increase.

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.

Candidal endocarditis is an uncommon and serious complication of invasive Candida infection in neonates. The aim of this study was to further characterise candidal endocarditis in neonates. Between 1995 and 2000, 56 patients were diagnosed with Candida bloodstream infections (CBSI) in the Neonatal Intensive Care Unit of Schneider Children's Medical Center of Israel. Five of them (9%) developed mycetoma of the right atrium. None of the patients had congenital heart disease or a central venous catheter in the right heart at the time of diagnosis. All were treated with amphotericin B alone or in combination with other antifungals, without surgical intervention. One patient died of the disease and one died later of polymicrobial sepsis and necrotizing enterocolitis. A review of the literature since 1980 yielded an additional 25 cases of candidal endocarditis. For the whole sample (n = 30) survival rate was 73.1%. Six of the 10 patients treated with antifungal agents and surgery survived (60%), compared with 13 of the 20 patients treated only medically (65%) (P = 1.0). Candida endocarditis in neonates differs from fungal endocarditis in adults in risk factors, clinical presentation and outcome. As the outcome of surgical and medical treatment are comparable, antifungal therapy alone may be a valid therapeutic option in high-risk cases.

The aims of the study were to define the duration of candidaemia in newborn infants and to determine the incidence of persistent hospital-acquired candidaemia and its associated morbidity and mortality compared with non-persistent candidaemia. This retrospective study, included 56 neonates admitted to the neonatal intensive care unit from 1996 to 2000 who had one or more positive blood cultures for Candida spp. The most prevalent pathogen was Candida albicans (64.3%). Mean disease duration was 6.9 +/- 5.5 days (median 6 days). Twenty-nine patients (52%) had a positive blood culture for >5 days (persistent candidaemia). There were no statistically significant differences between the infants with persistent and non-persistent candidaemia in background or predisposing clinical factors. Fungal endocarditis was present in four patients (13.7%) with persistent disease and one patient (3.7%) with non-persistent disease (odds ratio 4.19), and uveitis developed in one patient. Ten patients (17.8%) died--five with persistent and five with non-persistent disease (P = 1.0). These findings indicate that persistent neonatal candidaemia may be associated with an increased risk of Candida endocarditis, but not with other complications or increased mortality.

New immunosuppressive protocols and advanced surgical technique resulted in an improved outcome of pancreatic transplantation (PTx) with infection remaining the most common complication. Seventy-two enteric-drained whole PTxs performed at the Innsbruck University Hospital between September 2002 and October 2004 were retrospectively analyzed. Prophylactic immunosuppression consisted of either the standard protocol consisting of single bolus antithymocyteglobulin (ATG) (Thymoglobulin, Sangstat or ATG Fresenius) induction (9 mg/kg), tacrolimus (TAC), mycophenylate mofetil (MMF) and steroids (38 patients) or a 4-day course of ATG (4 mg/kg) tacrolimus and steroids with MMF (n = 19), or Sirolimus (n = 15). Perioperative antimicrobial prophylaxis consisted of Piperacillin/Tazobactam (4.5 g q 8 h) in combination with ciprofloxacin (200 mg q 12 h) and fluconazole (400 mg daily). Ganciclovir was used for cytomegalovirus (CMV) prophylaxis if donor was positive and recipient-negative. Patient, pancreas, and kidney graft survival at 1 year were 97.2%, 88.8%, and 93%, respectively, with no difference between the groups. All retransplants (n = 8) and single transplants (n = 8) as well as all type II diabetics and nine of 11 patients older 55 years received standard immunosuppression (IS). The rejection rate was 14% and infection rate 46% with no difference in terms of incidence or type according to the three groups. Severe infectious complications included intra-abdominal infection (n = 12), wound infection (n = 7), sepsis (n = 13), respiratory tract infection (n = 4), urinary tract infection (n = 12), herpes simplex/human herpes virus 6 infection (n = 5), CMV infection/disease (n = 7), post-transplant lymphoproliferative disorder (PTLD, n = 3), invasive filamentous fungal infection (n = 4), Clostridial/Rotavirus colitis (n = 1), and endocarditis (n = 1). All four patients in this series died of infectious complications (invasive aspergillosis n = 2) (one with Candida glabrata superinfection), invasive zygomycosis (n = 1), PTLD (n = 1). Five grafts were lost (vascular thrombosis n = 3, pancreatitis n = 1, noncompliance n = 1). Infection represented the most frequent complication in this series and all four deaths were of infectious origin. Better prophylaxis and management of infections now should be the primary target to be addressed in the field of pancreas transplantation.

Prosthetic heart valves, both mechanical and biological (xenograft valves, stented or unstented), show an inflammatory reaction (infective endocarditis), associated predominantly with bacterial/fungal infection. Somewhat surprisingly, no immune-mediated reaction has been reported thus far. This may, among other reasons, be related to the fact that the tissues are "fixed" with aldehydes and are virtually isolated from host circulation, separated by synthetic material (the valve stent and the fabric covering it). Stentless valves (especially these without fabric covering them), however, have no such "isolation" from the host circulation. While the Toronto-Stentless Porcine Valve has a covering of fabric, the Medtronic Freestyle valve has no such covering. It is perhaps not so surprising therefore that at the intermediate time point of 5 to 6 years, some valves are beginning to show such an immune reaction.

Cutaneous botryomycosis is an uncommon chronic suppurative bacterial skin infection that can mimic a fungal infection both clinically and histopathologically. Causative bacteria, most commonly Staphylococcus aureus, aggregate to form characteristic granules. We report the case of a 52-year-old black man who developed cutaneous botryomycosis of the hand following trauma. Routine bacterial cultures grew S aureus and Actinobacillus actinomycetemcomitans, a fastidious gram-negative bacillus known to cause periodontal disease, endocarditis, and actinomycosislike soft tissue infections. Despite culture-proven eradication of S aureus with long-term appropriate antibiotic therapy, the lesion, resolved only after fluoroquinolone treatment directed against A. actinomycetemcomitans, suggesting that A. actinomycetemcomitans was of etiologic significance.

Inflammatory abdominal aortic aneurysm is a rare cause of abdominal pain in young adults that may be difficult to diagnose in the Emergency Department. This case highlights the significance of this condition as a possible diagnosis in young patients presenting with abdominal symptoms. A 32-year old woman presented with lower abdominal and back pain. She had four previous visits to the Emergency Department and one hospital admission with similar symptoms and had been discharged without a definite diagnosis. Her vascular risk factors included hypercholesterolemia and smoking. A computed tomography (CT) scan showed a non-leaking infrarenal saccular abdominal aortic aneurysm and para-aortic lymphadenopathy. A transthoracic echocardiogram excluded endocarditis. There was no evidence of bacterial, viral, or fungal infection on blood and serum assays, and her autoimmune screen was negative. She underwent urgent open repair using a synthetic graft. The aneurysmal wall and para-aortic lymph node histology confirmed the diagnosis of inflammatory aneurysm with periaortitis. She remained asymptomatic at 8 months after surgery with no evidence of additional aneurysmal disease. Inflammatory abdominal aortic aneurysm is an unusual cause of abdominal pain in young adults. It is more likely in patients with persistent or recurrent abdominal symptoms.
