We describe a rare case of multifocal necrotizing fasciitis (NF) complicating a single vaccine injection. Injection of hepatitis B vaccine of a 16-year-old immunocompetent woman developed into rapidly spreading multifocal NF of the right arm and the thighs, with septic shock. Treatment with antimicrobial therapy and surgical debridements allowed amputation to be avoided with a favourable outcome. ⋯ Some strains of MSSA could harbor PVL and enterotoxins. PCR investigation is not frequent but could improve the understanding of the mechanisms of lesions. This case is in keeping with the increasing incidence of MSSA harboring PVL and enterotoxins with multifocal dissemination NF and emphasizes the necessary precautions for skin decontamination before vaccine injection.

Data on time-dependency of external ventricular drainage (EVD)- and lumbar drainage (LD)-associated meningoventriculitis (MV) are scarce and discussions on the subject are controversial; no data exist for infection rates (IR) relative to drainage-days. For this reason, we conducted an observational study to determine time-dependent IRs and to perform a risk factor analysis. ⋯ To the best of our knowledge, this study is the first to provide data on time dependency of EVD- and LD-associated MV-IR based on drainage-days. However, because of the limited scale of our study, it would be desirable to confirm these results in a more powerful larger study. In conclusion, we recommend that future efforts should be made to better identify preventable risk factors as well as to define time periods of higher risk for the difficult-to-diagnose MV infection as a first step in profiling high risk patients.

The aim of this study was to investigate the interaction between intravenous piperacillin/tazobactam treatment and Aspergillus galactomannan antigen (GM) and 1,3-beta-D: -glucan (BDG) test results in patients without known risk factors for invasive fungal infections (IFI). ⋯ No significant interaction was observed between piperacillin/tazobactam administration and Aspergillus GM and BDG assays. Positive results for these tests should be evaluated cautiously in patients at high risk for IFI receiving piperacillin/tazobactam.

There has been an increasing incidence of carbapenem-resistant Acinetobacter baumannii (CRAB) infections in recent years. The objective of this study was to determine specific risk factors for and outcome of bacteremia due to CRAB isolates among our ICU patients with A. baumannii bacteremia. ⋯ VAP due to CRAB and excess use of intravascular devices are the most important risk factors for CRAB bacteremia in our ICU. Severity of organ failure and WBC count at A. baumannii bacteremia onset are independently associated with mortality.

Surveillance of healthcare-associated infections (HCAIs) has become an integral part of infection control programs in several countries, especially in the intensive care unit (ICU) setting. In contrast, surveillance data on the epidemiology of ICU-acquired infections in Cyprus are limited. The aim of this study was to assess the risk of ICU-acquired infections and to identify areas for improvement in Cypriot hospitals by comparing observed incidence rates with international benchmarks and by specifying the microbiological and antibiotic resistance profiles of infecting organisms. ⋯ In comparison to international benchmarks, the markedly high rate of CL-BSI, the high rate of VAP and the resistance patterns of major infecting pathogens identified in this study emphasize the need to improve current practices for appropriate use and management of invasive devices in Cypriot ICUs.
