Reuse of catheters during cardiac catheterisation and interventions is a routine practice in our country. However, the reuse of catheters is complicated by the inherent difficulties in adequate sterilisation of these devices. Gas sterilisation with ethylene oxide has been found to be ineffective
OBJECTIVE
Nosocomial transmission of viral hepatitis and retrovirus infection has been reported. The expected risk is greatest for the hepatitis B virus (HBV). The duck HBV (DHBV) has similar biologic and structural characteristics to HBV and has been adopted as a suitable model for disinfectant
OBJECTIVE
To assess the efficacy of a standard cleaning and sterilization protocol employed during reuse of cardiac electrophysiology catheters on the infectivity of duck hepatitis B virus (DHBV; a surrogate for human hepatitis B virus), bovine viral diarrhea virus (BVDV; a surrogate for human
In 1987 it was anticipated that unsterilized tissues would transmit virus diseases such as hepatitis and HIV-1 from infected donors so a freeze-drying process for musculoskeletal tissue was developed to include terminal ethylene oxide (EO) exposure for 14 h. We found no studies of EO efficacy when
OBJECTIVE
Every country has standardized reprocessing guidelines for reducing the risk of microorganism transmission via reusable biopsy forceps. Sterilization is performed either by autoclaving or with the use of ethylene oxide (EO) gas. However, there are no clear standard global recommendations.
Since the inception of flexible fiberoptic endoscopes, disinfection of these instruments has been a problem. Soaking in glutaraldehyde does not always achieve sterilization, and often damages the scopes. Ethylene oxide can sterilize endoscopes; however, it is economically impractical because of a
The choice as to which of the two gaseous processes is best suited to individual hospital needs is a difficult one. Very few items are unable to tolerate 73 degrees C (LTSF) and these few can withstand 37 degrees C or 55 degrees C (EO). Unfortunately, LTSF is a 'moist' process and sterilizers have a
Nosocomial infections associated with interventional procedures have been attributed to improper decontamination of instruments. Disinfection of solid laparoscopic instruments, such as telescopes, by 2% glutaraldehyde and ethylene oxide was shown to be effective in preventing infection transmission.
Nitazoxanide (NTZ) is a highly hydrophobic nitrothiazolyl-salicylamide that displays antimicrobial activity against a variety of parasites, anaerobic bacteria and viruses. More recently, its effectiveness in the pharmacotherapy of chronic hepatitis, the leading cause of liver cirrhosis and
The high frequency of asymptomatic carriers of viral infections represents a major risk for transmission. Viral agents can be transmitted through blood or biologic fluids during diagnostic hysteroscopy. Routine disinfection methods to clean hysteroscopes cannot be considered adequate to prevent
Since the inception of the flexible nasopharyngolaryngoscope, sterility has been a primary concern. The increased incidence of hepatitis, tuberculosis, and acquired immunodeficiency syndrome has raised the fear of cross-contamination. Sterilization requires the use of ethylene oxide, which is
(1) Infections following invasive endoscopy are rare and are usually of endogenous origin. Nevertheless, infections do occur due to inadequate cleaning and disinfection and the use of contaminated rinse water and processing equipment. (2) Rigid and flexible operative endoscopes and accessories
OBJECTIVE
To determine the disinfection practices employed by North Carolina hospitals for endoscopes and other semicritical patient care items and to discuss minimally acceptable disinfection procedures for these items.
METHODS
A survey questionnaire was mailed to all North Carolina hospitals to
Branched-chain amino acids (BCAAs) are one of the important biomarkers for monitoring liver disease such as hepatitis or hepatoma. In this communication, we present the determination of the concentrations of BCAA in ascites by CE light-emitted diode-induced fluorescence (LEDIF) using 1.5% m/v
