Lactic Acid Bacteria and Bifidobacteria-Inhibited Staphylococcus epidermidis

Lau AS, Liong MT

Wounds, 2014 May;26(5):121-31.
PMID: 25856101

Lactic acid bacteria (LAB) and bifidobacteria are able to produce antimicrobial compounds to inhibit opportunisticwounding skin pathogen. The antimicrobial compounds produced are organic acids, putative bacteriocin, hydrogen peroxide, and diacetyl. Staphylococcus epidermidis is well-known as an opportunistic wounding skin pathogen in wound infections related to implanted medical devices.
The Potential of Gelam Honey in Promoting the Proliferative Phase of Corneal Reepithelialization

Azmi MF, Ghafar NA, Hamzah JC, Luan NS, Hui CK

Wounds, 2017 Nov;29(11):327-332.
PMID: 28678731

OBJECTIVE: The aim of this study is to investigate the potential bene ts of Gelam honey (GH) in promoting proliferation of ex vivo cor- neal epithelial cells (CECs) and its effects on the phenotypical features.
MATERIALS AND METHODS: Corneal epithelial cells were isolated from the corneas of rabbits (n = 6). The optimal dose of GH for CEC proliferation in both basal medium (BM) and cornea medium (CM) was determined via MTT (3-[4, 5-dimethyl thiazolyl-2]-2, 5-diphenyl tetrazolium bro- mide) assay. Morphology, gene and protein expressions, and cell cycle analysis of CECs were evaluated via phase contrast microscopy, real- time polymerase chain reaction, immunocytochemistry, and ow cytom- etry, respectively.
RESULTS: Corneal epithelial cells cultured in 0.0015% GH-supplemented media (BM + 0.0015% GH; CM + 0.0015% GH) demonstrated optimal proliferative capacity with normal polygonal- shaped morphology. Gelam honey potentiates cytokeratin 3 (CK3) gene expression in accordance with the cytoplasmic CK3 protein expression while retaining normal cell cycle of CECs.
CONCLUSION: Culture media treated with 0.0015% GH increased CEC proliferation while preserving its phenotypical features. This study demonstrated the potential devel- opment of GH-based topical treatment for super cial corneal injury.
Cost Effectiveness of a Platelet-rich Plasma Preparation Technique for Clinical Use

Wounds, 2018 Jul;30(7):186-190.
PMID: 30059343

INTRODUCTION: Despite limited clinical evidence, platelet-rich plasma (PRP) is currently used for the treatment of various soft tissue injuries, but optimal use of PRP has yet to be determined. In many instances, PRP is prepared using commercial devices that lack standardized preparation techniques and consistent quality of the PRP produced.
OBJECTIVE: The aim of this study is to explore a simple, easy, economical method of PRP preparation that is practical for clinical use.
MATERIALS AND METHODS: This cross-sectional study was conducted at the Sports Medicine Clinic at the University of Malaya Medical Centre, Malaysia. Participants were healthy postgraduate students and staff at the Sports Medicine Department. The PRP was prepared using a single centrifugation technique. Leukocyte and platelet levels were compared with that of a whole blood baseline and a commercial preparation kit.
RESULTS: The PRP produced using this technique contained significantly higher mean platelet (1725.0 vs. 273.9 x 109/L) and leukocyte (33.6 vs. 7.7 x 109/L) levels compared with whole blood. There was no significant difference in the mean platelet and leukocyte levels between the PRP produced in this study and by a commercial PRP system.
CONCLUSIONS: A single-centrifugation protocol using readily available materials in a typical clinical setting could produce PRP of comparable quality to those of a commercial PRP production system.
The Hanikoda Method: 3-layered Negative Pressure Wound Therapy in Wound Bed Preparation

Chik I, Kelly EG, Jarmin R, Imran FH

Wounds, 2016 Oct;28(10):360-368.
PMID: 27768574

Negative pressure wound therapy is a widely used method of wound dressing with various commercially available brands. The authors created the Hanikoda Method (HM) for effective wound bed preparation or definite wound closure.
Fulltext Fungicidal effectiveness of super-oxidized solution in vitro: potential implications for wound care

Krishnen R, Muniandy S

Wounds, 2023 Aug;35(8):E243-E247.
PMID: 37643448 DOI: 10.25270/wnds/23017

INTRODUCTION: Drug-resistant fungal infections in chronic wounds represent a major clinical challenge to clinicians. Fungal infections delay wound healing by prolonging inflammation and encouraging biofilm formation, which protects microbes against host defenses and anti-infective medications. As such, interventions that prevent and control nosocomial fungal infections without interfering with the wound healing process are increasingly required. Although conventional antiseptics can effectively exert fungicidal effects, they also have adverse effects on human cells. SOS is a well-known bactericidal agent that enhances the wound healing process, especially for chronic wounds. However, few studies have evaluated the antimicrobial activity of SOS on fungi.
OBJECTIVE: The objective of this study was to evaluate whether SOS exerts fungicidal activities against common fungal species.
MATERIALS AND METHODS: The efficacy of SOS was tested against 6 fungal species (Candida albicans, Candida auris, Candida tropicalis, Candida parapsilosis, Sporothrix schenckii, Trichophyton mentagrophytes) using an in vitro time-kill assay.
RESULTS: SOS achieved 99.9999% reduction of all tested fungi within 1 minute of exposure.
CONCLUSIONS: This study shows that SOS may be an effective tool for the prevention and control of fungal infections.
