Clinical Study on the Efficacy of Silver Ion Dressing Combined with Prontosan Gel Dressing in the Treatment of Diabetic Foot Ulcers and the Effect on Serum Inflammatory Factors

The Use of Polyhexanide and Betaine Combined Preparation in Adult Burn Care in Sri Lanka

Biofilm formation over burn wounds has led to persistent wound infection, poor wound healing, and resistance to antimicrobial therapy. This process ultimately leads to prolonged hospital stays and increased cost of burn wound care, especially in developing countries. Hence, large-area biofilm-targeted therapy should be a mainstay in burn wound care. Polyhexanide is a polymer used as a disinfectant, and betaine is a surfactant. We report a patient managed with a combined preparation of the above two substances. A 44-year-old patient sustained a 22% superficial partial-thickness and mid-dermal burns on the back and right arm after a high-voltage electrocution injury. The patient was treated with dressings containing the above preparation and closely monitored for the healing stages of the burn wound. Complete wound epithelialization with healthy granulation tissue was achieved within 15 days. No surface wound swab culture became positive during the treatment. The patient did not develop any fever spikes, and the white blood cell count was maintained at less than 12,000 mm-3 with a C-reactive protein level below 50 mg/L. No surgical intervention was needed for further management of the wound. Polyhexanide and betaine combined preparation may be used effectively on the superficial partial-thickness and mid-dermal burns to prevent wound infection and improve granulation and epithelialization. However, high-quality comparative evidence is needed for the confirmation.

Mini-Review: Tendon-Exposed Wound Treatments

BACKGROUND

Tendon-exposed wounds are complex injuries with challenging reconstructions and no unified treatment mode. Furthermore, insufficient tissue volume and blood circulation disorders affect healing, which increases pain for the patient and affects their families and caretakers.

REVIEW

As modern medicine advances, considerable progress has been made in understanding and treating tendon-exposed wounds, and current research encompasses both macro-and micro-studies. Additionally, new treatment methods have emerged alongside the classic surgical methods, such as new dressing therapies, vacuum sealing drainage combination therapy, platelet-rich plasma therapy, and live-cell bioengineering.

CONCLUSIONS

This review summarizes the latest treatment methods for tendon-exposed wounds to provide ideas and improve their treatment.

Application Effect of Silver-Containing Dressings in the Repair of Chronic Refractory Wounds

Chronic refractory wounds have complicated pathogenesis, repeatedly prolonged course of disease, high difficulty in cure, and may even endanger life due to the spread of wound infection. Silver ion dressing is a new type of dressing applied clinically in recent years. It can prevent infection and promote wound healing by releasing a low level of active silver ions into wound fluid or secretion. Some scholars have found that silver ion dressings can promote the healing of refractory wounds. In this study, 80 cases of chronic refractory wounds treated in our department from June 2019 to January 2022 were selected as the research subjects and the effect of silver ion dressing coverage on the repair of chronic refractory wounds after debridement was explored.

First Report on the Phenotypic and Genotypic Susceptibility Profiles to Silver Nitrate in Bacterial Strains Isolated from Infected Leg Ulcers in Romanian Patients

Silver-ion-based antiseptics are widely used in treating chronic leg ulcers and, given the emergence of resistance to such compounds, the investigation of silver susceptibility and resistance profiles of pathogenic strains isolated from this type of wound is a topic of great interest. Therefore, in this study, 125 bacterial strains isolated from 103 patients with venous ulcers were investigated to elucidate their susceptibility to silver-nitrate solutions in planktonic and biofilm growth states, and the associated genetic determinants. The isolated strains, both in the planktonic and biofilm growth phases, showed high sensitivity to the standard concentration of 1/6000 silver-nitrate solution. It was noticed that even at concentrations lower than the clinical one (the first 2–3 binary dilutions in the case of planktonic cultures and the first 6–7 binary dilutions in the case of biofilms), the antiseptic solution proved to maintain its antibacterial activity. The phenotypic results were correlated with the genetic analysis, highlighting the presence of silver-resistance genes (sil operon) in only a few of the tested Staphylococcus sp. (especially in S. aureus) strains, Escherichia coli and Pseudomonas aeruginosa strains. These results demonstrate that despite its large use, this antiseptic remains a viable treatment alternative for the management of chronic leg wounds.
