    ABSTRACT: The incidence of acute hepatitis B (AHB) in Italy, mostly sustained by hepatitis B virus (HBV) genotype D, has significantly decreased in the last two decades, but the new HBV strains introduced through immigrant populations from countries with a higher endemicity constitute a new emergency. HBV-genotype D still predominates in AHB, the subgenotype D3 being associated with parenteral transmission, and the recently emerging subgenotype A2 with unsafe sexual intercourse. Genetic, phylogenetic and evolutional analyses are powerful tools for countries with high immigration rates to monitor new viral strains with different aggressiveness and a different response to therapy.

    ABSTRACT: Tigecycline, the first member of the glycylcyclines, has been approved for complicated skin and soft tissue infections (cSSTIs) and complicated intra-abdominal infections (cIAIs). It has a wide range of activity against Gram-positive and Gram-negative bacteria, including anaerobes. Since its approval, the worldwide clinical use of tigecycline has been heterogeneous, either as a monotherapy or as a part of combination therapy, almost exclusively at the standard dosage, in patients with community-acquired (CA) infections as well as health-care associated (HCA) or nosocomial infections (HA), including infections caused by multidrug-resistant (MDR) bacteria. In recent years, issues and warnings of an increased mortality in these heterogeneous patients treated with tigecycline have been raised by meta-analyses and by regulatory agencies. Re-trialing tigecycline is a proposal, based on epidemiological, clinical, microbiological and pharmacological considerations, to distinguish patients who may be treated with monotherapy, according to the official indications and dosages, from those treated with combination treatment, mostly with high dosages in the setting of nosocomial IAIs, possibly caused by MDR bacteria or as a carbapenem-sparing strategy. Whilst available clinical data and guidelines suggest caution with monotherapy in severe infections, experience worldwide indicates that combination treatment with high-dosage tigecycline is increasingly used.

    ABSTRACT: HIV-1-associated Guillan-Barr� syndrome (hGBS) is an ascendant progressive polyradiculoneuropathy described throughout the course of the viral disease, mainly associated with the acute retroviral syndrome. HGBS is occasionally described in severely immunocompromised subjects in the context of the immune reconstitution inflammatory syndrome. The case described occurred soon after the start of a combined antiretroviral treatment in an HIV-1 infected patient with ulcerative colitis in the absence of severe immunosuppression. This manifestation may be interpreted as an uncommon appearance of an immune reconstitution syndrome in the presence of a predisposing autoimmune pathology.

    ABSTRACT: Staphylococcus aureus can be responsible for oral and dental healthcare-associated infections. Patients with high salivary S. aureus levels are potential sources of infection, because saliva is spread in the environment during dental therapy. This study assessed the salivary S. aureus carriage rate in 97 children (6-12 years) in good general health, attending a paedodontic department. Samples of unstimulated saliva were collected, S. aureus was presumptively identified. The salivary carriage rate was 43% (95% confidence interval, 33%-53%). 6.2% children harboured levels >103 colony forming units/mL. These data suggest that the risk for environmental contamination and infection in dental healthcare settings could be high.

    ABSTRACT: The impact of Adenovirus as agent of non-gonococcal urethritis (NGU) is still poorly documented in the literature. We describe two cases showing that adenoviral infection should be reasonably hypothesized in men with dysuria and scant urethral discharge in addition to meatus inflammation and/or edema (meatitis) or conjunctivitis. Case 1: a 55-year-old man came to our observation in July 2012 referring a 5-day-history of intense dysuria and scant mucoid urethral discharge. Physical examination revealed the urethral discharge referred, but also modest meatitis and an intense conjunctival hyperemia on his right eye. Adenoviral infection was investigated and Adenovirus DNA (type 37) was detected in both the urethral and conjunctival swabs. Case 2: a 43-year-old man with intense dysuria, started 4-5 days earlier, came to our attention with his wife in August 2012. Scant urethral mucoid secretions, severe meatal inflammation of the male patient were revealed during physical examination. His wife instead complained of a 2-day history of intense burning eyes. Adenoviral infection was investigated and Adenovirus DNA (type 37) was positive both in the male urethral swab and in his wife�s conjunctival swab. Adenovirus seems to cause a distinct and recognisable clinical syndrome in men presenting with urethritis. Studies on the prevalence and role of Adenovirus as a causative agent of urethritis are limited. Moreover, as rapid advanced molecular microbiology is now available, we believe that extending the search to Adenovirus in sexually active men with dysuria, scant discharge in addition to meatitis or conjunctivitis, should be a useful approach improving our understanding about adenoviral NGU, and especially avoiding or stopping unnecessary empirical antibiotic therapy.

    ABSTRACT: This study characterized the occurrence of carbapenem resistance of Acinetobacter baumannii isolates in a tertiary care hospital in Saudi Arabia. From January 2010 until February 2012, Acinetobacter spp. isolates were collected from different wards and were identified using Vitek 2 system and 16S rRNA gene sequencing. Vitek 2 system and Etest were used for susceptibility testing. PCR and Pulse field gel electrophoresis (PFGE) were used for detecting and typing genes associated with carbapenem resistance. A total of 141 isolates were identified as A. baumannii. A total of 46 (32.6%) isolates were carbapenem-resistant Acinetobacter baumannii (CRAB) isolates and had wild diversity by PFGE. Metallo ?-lactamase confirmatory test was positive for 43 isolates with negative PCR for blaIMP and blaVIM. Among the 46 CRAB strains, 37 isolates harbored blaOXA-23 which was encoded downstream of ISAba1 and 1 isolate had ISAba1 encoded upstream blaOXA-51. These data reveal that the interhospital transmission of CRAB isolates was apparently insignificant. BlaOXA-23 adjacent to ISAba1 was the main mechanism of carbapenem resistance in these isolates. To our knowledge, this is the first molecular study characterizing carbapenem resistance in A. baumannii in the Eastern Province of Saudi Arabia.

    ABSTRACT: We describe an outbreak of a carbapenemase-producing Klebsiella pneumoniae sequence type 258 (ST258) clone in an Italian hospital during two months in 2010. The rapid detection and management of the eleven patients colonized and infected with KPC-producing K.pneumoniae curbed the spread of this multidrug-resistant organism.
