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.

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.

The administration of antibiotics by the inhaled route is a widely recognized treatment in patients with cystic fibrosis (CF) and bronchiectasis. Tobramycin solution for inhalation (TOBI) has been available for many years and is licensed in the USA and Europe. While strong data support the use of aerosolized antibiotics for the treatment of respiratory infections in patients with CF or bronchiectasis, only a few clinical studies have examined the role of aerosolized antibiotics in the treatment of pneumonia, including ventilator-associated pneumonia (VAP) in these patients. ⋯ Recent publications demonstrate the clinical benefits from administering inhaled aminoglycosides or polymyxins in patients with hospital-acquired pneumonia or VAP. In addition to antibiotics, antifungals, and antivirals have been administered by inhalation to specific groups of critically ill patients. However, randomized controlled trials dealing with the administration of anti-infective agents via the respiratory tract are necessary in order to validate the efficacy, safety, advantages, and disadvantages of this therapeutic approach for the treatment of nosocomial pneumonia.

Review Case Reports
Streptococcus anginosus (Streptococcus milleri Group) Pyomyositis in a 50-Year-Old Man with Acquired Immunodeficiency Syndrome: Case Report and Review of Literature.
We describe the first reported case of bacterial pyomyositis of the right thigh caused by Streptococcus anginosus (S. milleri group) in an HIV-infected patient. The clinical presentation was complicated by multiple ring-enhancing lesions detected on magnetic resonance imaging of the brain. ⋯ Clinicians should considerS. anginosus as a causative pathogen in HIV-associated pyomyositis, particularly in complex presentations. Prompt surgical drainage may minimize complications due to S. anginosus, a pathogen associated with significant sequelae due to its invasive nature.
