Acanthamoeba keratitis (AK) is a sight-threating infection of the cornea that mostly affects contact lens wearers. Until now, AK treatment remains very difficult due to the existence of a highly resistant cyst stage in the life cycle of Acanthamoeba which is extremely resistant to most of the available anti-amoebic compounds. Moreover, current treatment of AK is usually based in the combination...

An ex vivo porcine skin explant biofilm model that preserves key properties of biofilm attached to skin at different levels of maturity (0-3 days) was used to assess the efficacy of commercially available antimicrobial dressings and topical treatments. Assays were also performed on the subpopulation of antibiotic tolerant biofilm generated by 24 hours of pre-treatment with gentamicin (120× mini...

BACKGROUND Bacterial infections are a well-known complication of traumatic amputations. In cases involving contact with soil or water contaminated with manure, one also must be aware of infections with fungi, particularly Scedosporium spp. We report on an immunocompetent trauma patient with an infection caused by a recently described Scedosporium species, S. aurantiacum. METHODS Case report a...

OBJECTIVE A randomized controlled trial to evaluate the effectiveness of a polyhexamethylene biguanide (PHMB) foam dressing compared with a similar non-antimicrobial foam for the treatment of superficial bacterial burden, wound-associated pain, and reduction in wound size. SETTING AND PARTICIPANTS This study was conducted in 2 wound healing clinics-a university hospital-based clinic and a com...

Introduction. – Taking care of a patient with an infected pressure sore necessitates a diagnosis allowing for a suitable treatment strategy. Aims. – To choose the dressings and topical antimicrobial agents that can be used as of 2012 in treatment of an infected pressure sore. Methods. – A systematic review of the literature with queries to the databases Pascal Biomed, PubMed and Cochrane Librar...

AIM The aim of the study was to evaluate the ability of in vitro planktonic and immobilized cell models for determining the antimicrobial efficacy of common antimicrobial wound dressings. METHODS AND RESULTS Five strains of Acinetobacter baumannii, Pseudomonas aeruginosa and methicillin resistant Staphylococcus aureus were tested against four antimicrobial wound dressings containing silver, h...

Tinea pedis is a preventable skin disease common in elderly or diabetic patients. Daily foot washing is effective for prevention, but can be difficult for many patients. Additionally, conventional methods cannot eliminate fungi within the stratum corneum, a common site for fungal invasion. This study investigates the antifungal effects, cytotoxicity, permeability, and efficacy of non-woven text...

A potentiometric titration method using a cationic surfactant as an indicator cation and a plasticized poly(vinyl chloride) membrane electrode sensitive to the cationic surfactant is proposed for the determination of polyhexamethylene biguanide hydrochloride (PHMB-HCl), which is a cationic polyelectrolyte. A sample solution of PHMB-HCl containing an indicator cation (hexadecyltrimethylammonium ...
