Risk for hepatitis B and C virus transmission in nail salons and barbershops and state regulatory requirements to prevent such transmission in the United States.

Context: The potential for hepatitis B and C virus (HBV/HCV) transmission in nail salons and barbershops has been reported, but a systematic review has not been conducted. These businesses are regulated by state cosmetology or barbering boards, but adequacy of sanitary requirements has not been evaluated.

Objectives: To conduct literature review to assess risk for HBV/HCV transmission in nail salons and barbershops and to evaluate sanitary requirements in HBV/HCV prevention in these businesses in 50 states and District of Columbia.

Transmission of hepatitis B virus from an orthopedic surgeon with a high viral load.

Background: During the evaluation of a needle-stick injury, an orthopedic surgeon was found to be unknowingly infected with hepatitis B virus (HBV) (viral load >17.9 million IU/mL). He had previously completed two 3-dose series of hepatitis B vaccine without achieving a protective level of surface antibody.

Health care-associated bloodstream infections associated with negative- or positive-pressure or displacement mechanical valve needleless connectors.

Background: Health care-associated, central venous catheter-related bloodstream infections (HA-BSIs) are a major cause of morbidity and mortality. Needleless connectors (NCs) are an important component of the intravenous system. NCs initially were introduced to reduce health care worker needlestick injuries, yet some of these NCs may increase HA-BSI risk.

Updated review of blood culture contamination.

Blood culture contamination represents an ongoing source of frustration for clinicians and microbiologists alike. Ambiguous culture results often lead to diagnostic uncertainty in clinical management and are associated with increased health care costs due to unnecessary treatment and testing. A variety of strategies have been investigated and employed to decrease contamination rates.

Diagnosis and management of long-term central venous catheter infections.

The pathogenesis, diagnosis, and management of central venous catheter infections differ between short-term and long-term catheters. This review summarizes available data regarding the diagnosis and management of catheter-related bloodstream infections (CRBSIs) associated with long-term catheters. A review of various diagnostic modalities is provided, including methods of CRBSI diagnosis for catheters that are retained.

Ultraviolet light disinfection of hospital water for preventing nosocomial Legionella infection: a 13-year follow-up.

Background And Objective: CDC has estimated that 23% of Legionella infections are nosocomial. When a new hospital was being constructed and a substantial increase in transplantation was anticipated, an ultraviolet light apparatus was installed in the water main of the new building because 27% of water samples from taps in the old hospital contained Legionella. This study reports the rate of nosocomial Legionella infection and water contamination since opening the new hospital.

Evaluation and treatment of acute bronchitis at an academic teaching clinic.

Background: Randomized controlled trials have demonstrated that antibiotics provide no benefit for acute bronchitis, yet 55 to 90% of patients who receive this diagnosis are treated with antibiotics. Given substantial data against antibiotics for acute bronchitis, it could be expected that physicians at academic teaching institutions would be less likely to prescribe antibiotics. However, limited data of antibiotic use for acute bronchitis in this setting has been published.

Influenza in the acute hospital setting.

Influenza poses special hazards inside healthcare facilities and can cause explosive outbreaks of illness. Healthcare workers are at risk of acquiring influenza and thus serve as an important reservoir for patients under their care. Annual influenza immunisation of high-risk persons and their contacts, including healthcare workers, is the primary means of preventing nosocomial influenza.
