Peritoneal fibrosis (PF) is a serious complication in various clinical settings, but the mechanisms driving it remain to be fully determined. Connective tissue growth factor (CTGF) is known to regulate fibroblast activities. We therefore examined if CTGF inhibition has anti-fibrotic effects in PF. PF was induced by repetitive intraperitoneal injections of chlorhexidine gluconate (CG) in mice with type I pro-collagen promoter-driven green fluorescent protein (GFP) expression to identify fibroblasts. FG-3019, an anti-CTGF monoclonal antibody, was used to inhibit CTGF...

INTRODUCTION: Around 30% of peripherally inserted central catheters (PICCs) fail from vascular, infectious or mechanical complications. Patients with cancer are at highest risk, and this increases morbidity, mortality and costs. Effective PICC dressing and securement may prevent PICC failure; however, no large randomised controlled trial (RCT) has compared alternative approaches. We designed this RCT to assess the clinical and cost-effectiveness of dressing and securements to prevent PICC failure...

REVIEW
Jaiben George, Alison K Klika, Carlos A Higuera
Prosthetic joint infection (PJI) is a serious complication after total joint arthroplasty (TJA). Chlorhexidine is a widely used antiseptic because of its rapid and persistent action. It is well tolerated and available in different formulations at various concentrations. Chlorhexidine can be used for pre-operative skin cleansing, surgical site preparation, hand antisepsis of the surgical team and intra-articular irrigation of infected joints. The optimal intra-articular concentration of chlorhexidine gluconate in irrigation solution is 2%, to provide a persistent decrease in biofilm formation, though cytotoxicity might be an issue...

One of the biggest challenges in endodontics is the complete disinfection of root canals. In addition to mechanical preparation, the technique traditionally also involves channel disinfection with other agents such as sodium hypochlorite, hydrogen peroxide, chlorhexidine, or a combination of these. Some bacterial species are particularly resistant to eradication. Using Enterococcus faecalis in this preliminary study, we tested the bactericidal effectiveness of the Fenton reaction and the photo-Fenton reaction using an LED light with a 400-nm wavelength...
