The prevalence of Candida parapsilosis, an opportunistic human pathogenic fungal species, is increasing at an alarming rate in the hospital environment. Patients at risk for C. parapsilosis infection include those with immunosuppression, such as individuals with cancer, AIDS, and low birth weight premature neonates as well as patients that had undergone abdominal surgery. Neonatal candidiasis caused by C. parapsilosis has been widely reported across the globe. Various reports have shown that, compared to other Candida species, certain C...

Pseudozyma aphidis is an environmental Basidiomycete yeast, and has been involved in the ten past years in rare cases of invasive infection. Pseudozyma species are naturally resistant to caspofungin and often present decreased susceptibility or resistance to fluconazole. This fungus may be difficult to recognize and misidentifications are reported with conventional phenotypical methods. We report a case of P. aphidis invasive infection in an adult with a metastatic ampulloma who had gone through digestive surgery...

Canine cryptococcosis cases are typically reported as neurologic, disseminated, or both. There have been few reports of other parenchymal organ involvement. Dogs infected with Cryptococcus spp. are likely to develop central nervous system involvement, and those that are severely affected are treated aggressively with surgery and/or amphotericin B. This report describes two cases of canine abdominal cryptococcosis: one boxer with primary alimentary cryptococcosis alone and one miniature schnauzer with pancreatic and disseminated cryptococcosis...

BACKGROUND: Candida species are the main cause of hospital acquired fungal bloodstream infections. The main risk factors for candidemia include parenteral nutrition, long-term intensive care, neutropenia, diabetes, abdominal surgery and the use of central venous catheters. The antifungal drugs used to treat candidemia are mainly the echinocandins, however some isolates may be resistant to these drugs. AIMS: This work aims to evaluate the in vitro susceptibility patterns of various Candida species isolated from blood samples and provide their identification by molecular characterization...

A prospective, observational, multicentre study of invasive candidosis (IC) in surgical patients in intensive care units (ICUs) was conducted from 2006 to 2008 in 72 ICUs in 14 European countries. A total of 779 patients (62.5% males, median age 63 years) with IC were included. The median rate of candidaemia was 9 per 1000 admissions. In 10.8% the infection was already present at the time of admission to ICU. Candida albicans accounted for 54% of the isolates, followed by Candida parapsilosis 18.5%, Candida glabrata 13...

INTRODUCTION: Historically, Candida albicans has represented the most common cause of candidemia. However, the proportion of bloodstream infections due to non-albicans Candida species has increased. Because of the risk for candidemia in intra-abdominal surgical patients, some experts advocate the use of fluconazole prophylaxis. The impact of this practice on the distribution of Candida species isolated in breakthrough fungal infections in this population is unknown. We examined the association of fluconazole prophylaxis with the distribution of Candida species in intra-abdominal surgery patients...

Invasive candidiasis is a leading cause of mortality. Candidaemia is the most common clinical presentation of invasive candidiasis but more that 30% of these infections do not yield positive blood cultures. Candida albicans remains the predominant aetiology, accounting for 50% of all cases. However, there has been an epidemiological shift in the last decades. Some species of Candida different to C. albicans have emerged as an important cause of severe candidaemia as they can exhibit resistance to fluconazole and other antifungal agents...

In our part of the world invasive fungal infections include invasive yeast infections with Candida as the absolutely dominating pathogen and invasive mould infections with Aspergillus as the main organism. Yeasts are part of our normal micro-flora and invasive infections arise only when barrier leakage or impaired immune function occurs. On the contrary, moulds are ubiquitous in the nature and environment and their conidia inhaled at a daily basis. Hence invasive mould infections typically arise from the airways whereas invasive yeast infections typically enter the bloodstream causing fungaemia...

INTRODUCTION: intra-abdominal candidiasis (IAC) may include Candida involvement of peritoneum or intra-abdominal abscess and is burdened by high morbidity and mortality rates in surgical patients. Unfortunately, international guidelines do not specifically address this particular clinical setting due to heterogeneity of definitions and scant direct evidence. In order to cover this unmet clinical need, the Italian Society of Intensive Care and the International Society of Chemotherapy endorsed a project aimed at producing practice recommendations for the management of immune-competent adult patients with IAC...

BACKGROUND: Bloodstream infections due to Candida species cause significant morbidity and mortality, and the epidemiology of Candida infection is changing. Surveillance for candidemia is necessary to detect trends in species distribution and antifungal resistance. METHODS: The medical and electronic records of all patients who had candidemia at the authors' hospital from 2009 to 2011 were reviewed for demographic data and clinical information, including the infecting Candida species, resistance to antifungals and survival, and the presence of risk factors associated with candidemia...

Intra-abdominal infection (IAI) is a frequent complication found in surgical intensive care unit (SICU) and continues to be associated with considerable mortality. Tigecycline, the first-in-class glycylcycline has demonstrated a broad spectrum of activity against a wide range of bacteria commonly found in IAI. This observational retrospective study aimed to describe the experience with tigecycline for serious nosocomial IAI in the SICU. Data were collected from 23 consecutive patients admitted to SICU with serious nococomial IAI who had received empirical treatment with tigecycline...

INTRODUCTION: Laparoscopic surgery is following a natural course as it decreases surgical aggression on the abdominal wall without undermining the curative and functional results. Although it is still being developed, single port surgery has meant an advance in this sense. MATERIAL AND METHODS: We present the first single port laparoscopic pyelolithectomy surgery in horseshoe kidney, using conventional rigid instruments. The case of an 18-year old patient with BMI of 19 in whom the imaging tests (urogram and computed tomography) showed a horseshoe kidney with left coralliform lithiasis and discrete calyceal ectasia is presented...

Candida is one of the most common causes of nosocomial bloodstream infections. Candidemia is not confined to hematological patients, intensive care units or abdominal surgery wards, but it is remarkably frequent in the internal medicine setting. High mortality associated with candidemia can be reduced by prompt, appropriate antifungal therapy. The epidemiology of species has been shifting toward non-albicans strains. Significant improvements in nonculture-based diagnostic methods, such as serological markers, have been made in recent years, and novel diagnostic techniques should be further studied to enable early pre-emptive therapy...

This part of the EFISG guidelines focuses on non-neutropenic adult patients. Only a few of the numerous recommendations can be summarized in the abstract. Prophylactic usage of fluconazole is supported in patients with recent abdominal surgery and recurrent gastrointestinal perforations or anastomotic leakages. Candida isolation from respiratory secretions alone should never prompt treatment. For the targeted initial treatment of candidaemia, echinocandins are strongly recommended while liposomal amphotericin B and voriconazole are supported with moderate, and fluconazole with marginal strength...

Invasive candidiasis ranges from 5 to 10 cases per 1,000 ICU admissions and represents 5% to 10% of all ICU-acquired infections, with an overall mortality comparable to that of severe sepsis/septic shock. A large majority of them are due to Candida albicans, but the proportion of strains with decreased sensitivity or resistance to fluconazole is increasingly reported. A high proportion of ICU patients become colonized, but only 5% to 30% of them develop an invasive infection. Progressive colonization and major abdominal surgery are common risk factors, but invasive candidiasis is difficult to predict and early diagnosis remains a major challenge...

Candida species, including Candida glabrata (CG), are common causes of bloodstream infections among intensive care unit (ICU) patients. Many CG isolates have decreased susceptibility to fluconazole. Constructing a scoring model of factors associated with CG candidemia in ICU patients that can be used if fluconazole susceptibility testing is not readily available. We identified patients with candidemia that were admitted to the ICU of the Mayo Clinic in Rochester, Minnesota from 1998 to 2006. Using patient demographical and clinical data abstracted via chart review, a multivariable logistic regression model was developed to distinguish those with CG candidemia...
