Impact of an outpatient parenteral antimicrobial treatment (OPAT) as part of a paediatric-specific PROA program.

Introduction: Outpatient parenteral antimicrobial treatment (OPAT) is an alternative to in-patient care in carefully selected patients. This study presents a self-administration OPAT program integrated within the pediatric antibiotic stewardship program (ASP) in a pediatric tertiary care center.

Material And Methods: Descriptive, retrospective and unicentric study.

Differences in Neisseria gonorrhoeae population structure and antimicrobial resistance pattern between men who have sex with men and heterosexuals.

This study compared the antimicrobial susceptibility and genotypes of strains of Neisseria gonorrhoeae isolated from men who have sex with men (MSM) and from heterosexuals. One hundred and eleven strains were characterized from 107 patients, comprising 57 strains from 54 heterosexuals and 54 strains from 53 MSM. Antimicrobial resistance rates were higher in strains from heterosexual patients, with resistance to cefixime (P = 0·0159) and ciprofloxacin (P = 0·002) being significantly higher.

Neisseria gonorrhoeae antimicrobial susceptibility in Barcelona: penA, ponA, mtrR, and porB mutations and NG-MAST sequence types associated with decreased susceptibility to cephalosporins.

The aims of this study were to determine the antimicrobial susceptibility of Neisseria gonorrhoeae (NG) in our area, to analyze the molecular mechanisms involved in cephalosporins resistance, and to undertake molecular typing of our NG strains. Antimicrobial susceptibility was determined using the Etest. The genes penA, mtrR, penB, and ponA were studied.

[Neisseria gonorrhoeae: antimicrobial resistance and study of population dynamics. Situation in Barcelona in 2011].

Background: Due to the high rates of antimicrobial resistance to certain antibiotics, together with the emergence of Neisseria gonorrhoeae (NG) with reduced susceptibility and resistance to third-generation cephalosporins, gonococcal infection is becoming a public health problem. The objectives of the study were: To keep track of the antimicrobial susceptibility of NG strains obtained from January to August 2011. To study the population dynamics.

[Necrotizing fasciitis due to community-acquired panton-valentine leukocidin methicillin resistant Staphylococcus aureus].

Community-Acquired Methicillin-Resistant Staphylococcus aureus (CA-MRSA) is a worldwide emerging pathogen that is able to produce serious skin and soft- tissue infections such as necrotizing fasciitis, as well as pneumonia and osteomyelitis. We present a 14 month child with necrotizing fasciitis, confirmed by magnetic resonance imaging, produced by CA-MRSA Panton-Valentine leukocidin producer. The clinical outcome was good after early surgical treatment and the administration of intravenous clindamycin for two weeks.
