Active Lumbar Spondylodiscitis on [Ga]Ga-PSMA-11 PET/CT Mimicking Bone Metastasis.

We report a [Ga]Ga-PSMA-11 positron emission tomography/computed tomography (PET/CT) scan of a 71-year-old man with metastatic castration-resistant prostate cancer (mCRPC) and concomitant active lumbar spondylodiscitis, both PSMA-positive on a PET/CT scan. This interesting image should advise colleagues to consider spondylodiscitis as a differential diagnosis of PSMA-positive findings in the spine, particularly if intervertebral space and soft tissue are involved.

An outbreak of cryptosporidiosis associated with drinking water in north-eastern Italy, August 2019: microbiological and environmental investigations.

is a leading global cause of waterborne disease, with many reported outbreaks related to main water supplies. In August 2019, an outbreak of cryptosporidiosis involving 80 cases occurred among 114 vacationers in a small municipality located in the Tuscan-Emilian Apennines, north-eastern Italy. After excluding a potential food-borne outbreak, the epidemiological investigation focussed on the hypothesis of a waterborne outbreak.

Anaerobic bloodstream infections in Italy (ITANAEROBY): A 5-year retrospective nationwide survey.

Introduction: A lack of updated data on the burden and profile of anaerobic bloodstream infections (ABIs) exists. We assessed the incidence of ABIs and trends in antimicrobial resistance in anaerobes isolated from blood in Italy.

Material And Methods: We conducted a retrospective study on 17 Italian hospitals (2016-2020).

Virulence Determinants in Clones Causing Osteomyelitis in Italy.

is the most common pathogen causing osteomyelitis (OM). The aim of this study was to explore the clonal complex (CC) distribution and the pattern of virulence determinants of isolates from OM in Italy. Whole-genome sequencing was performed on 83 isolates from OM cases in six hospitals.

Multicenter evaluation of the RAPIDEC® CARBA NP test for rapid screening of carbapenemase-producing Enterobacteriaceae and Gram-negative nonfermenters from clinical specimens.

The rapid diagnosis of carbapenemase-producing (CP) bacteria is essential for the management of therapy and infection control. In this study, RAPIDEC® CARBA NP (RCNP) was evaluated for the rapid screening of CP Enterobacteriaceae, Acinetobacter baumannii complex, and Pseudomonas aeruginosa from clinical specimens collected at five Italian hospitals. Firstly, each site tested 20 well-characterized strains in a blinded fashion.

Biological and clinical outcomes in the elderly with left ventricular dysfunction: Are there differences between on-pump and off-pump coronary artery bypass grafting?

Aim: To compair biological and clinical outcomes after off-pump coronary artery bypass grafting (OPCABG) and conventional on-pump coronary artery bypass grafting (CCABG) in the elderly with left ventricular (LV) dysfunction.

Material Of Study: We retrospectively reviewed 90 consecutive patients aged more than 75 years with preoperative left ventricular ejection fraction (LVEF) < 50% who underwent isolated coronary artery bypass grafting at our Institution between January 2000 and July 2009. According to operative technique, patients were categorized in to the OPCABG group (39 patients) or in to the CCABG group (51 patients).

Detection and partial characterization of a bacteriocin-like substance produced by Lactobacillus fermentum CS57 isolated from human vaginal secretions.

Lactobacilli (150) from human vaginal secretions were tested for the production of antimicrobial substances which can provide a physiological defense against the pathogenic microorganisms in the vaginal area. Sixteen of the isolates (10.6%) showed antibacterial activity against one or several closely related microorganisms used as indicators.

Evaluation of a double synergy differential test (DSDT) for differential detection of ESBL and AmpC-type β-lactamases in Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis.

This work describes a simple and practical double synergy differential test (DSDT) that couples the detection of ESBLs and AmpC-type enzymes by means of a combo-disk approach using cefotaxime and ceftazidime as indicator substrates, and clavulanate and boronic acid as enzyme inhibitors. The DSDT was tested with a collection of 118 Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis strains with different beta-lactamase profiles, and proved to be highly sensitive and specific for the detection of ESBL and AmpC-producing isolates.

Polyclonal diffusion of beta-lactamase-producing Enterococcus faecium.

We describe here the isolation of 8 beta-lactamase-producing multidrug-resistant Enterococcus faecium isolates in 2010. All strains showed diverse pulsed-field gel electrophoresis (PFGE) profiles, all belonging to the same clonal complex, CC17. By PCR and hybridization experiments, the entire blaZ-blaI-blaR1 operon was found.

Staphylococcus aureus in a northern Italian region: phenotypic and molecular characterization.

Background: Staphylococcus aureus is a leading cause of community-acquired infections and healthcare-associated infections. Epidemiological data are useful for understanding the dynamics of the diffusion of this pathogen, and to plan control activities and monitor their efficacy.

Methods: S.

Accuracy of automated and manual systems for susceptibility testing of Pseudomonas aeruginosa to piperacillin and piperacillin-tazobactam.

This study aimed to evaluate the accuracy of routine systems (Vitek2 cards AST-N022 and AST-N026; Kirby Bauer; Etest) for susceptibility testing of Pseudomonas aeruginosa to piperacillin and piperacillin-tazobactam. Vitek2 (card AST-N022) showed the worst performance; the other three methods (Vitek2 card AST-N026, Kirby-Bauer and E-test) performed comparably but never fulfilled the minimal standard proposed by FDA.
