Abstract: (1) Background: Diabetes-related foot ulcers (DFUs) are a severe complication of diabetes mellitus (DM), with a five-year mortality rate of around 40%. Our study aimed to explore the effects of transcutaneous application of carbon dioxide (CO2 therapy) on DFU healing and recurrence rate, as well as diabetic polyneuropathy. (2) Methods: Adults with at least one chronic DFU were invited to undergo 20 50-min-long CO2 therapies within 4 weeks. After the completion of the last CO2 therapy, the effect of the therapies on wound healing and diabetic polyneuropathy was assessed, and 1 year later, we evaluated the incidence rate of DFU recurrence. (3) Results: Thirty-five subjects with DM and forty DFUs (ischemic: 15, neuropathic: 8, neuroischemic: 17) participated in our trial. After 4 weeks, 67.5% of all DFUs healed, whereas the reduction of the surface area of the unhealed wounds (74.0% ± 22.3%) was statistically significant. The restoration of protective sensations was also statistically significant. All unhealed wounds received standard care and healed within 2 additional weeks. The recurrence rate after 1 year was 17.5%. None of the patients required antibiotic treatment, hospitalization, or amputation. (4) Conclusion: CO2 therapy is a promising therapeutic intervention for treating DFUs and improving diabetic polyneuropathy.

Abstract: Introduction. Chronic wounds and the infections associated with them are responsible for a considerable escalation in morbidity and the cost of health care. Infection and cellular activation and the relation between cells are 2 critical factors in wound healing. Since chronic wounds offer ideal conditions for infection and biofilm production, good wound care strategies are critical for wound healing. Topical antiseptics in chronic wounds remain in widespread use today. These antiseptics are successful in microbial eradication, but their cytotoxcity is a controversial issue in wound healing. Objective. The aim of this study was to investigate the effect of stabilized hypochlorous acid solution (HOCl) on killing rate, biofilm formation, antimicrobial activity within biofilm against frequently isolated microorganisms and migration rate of wounded fibroblasts and keratinocytes. Materials and Methods. Minimal bactericidal concentration of stabilized HOCl solution for all standard microorganisms was 1/64 dilution and for clinical isolates it ranged from 1/32 to 1/64 dilutions Results. All microorganisms were killed within 0 minutes and accurate killing time was 12 seconds. The effective dose for biofilm impairment for standard microorganisms and clinical isolates ranged from 1/32 to 1/16. Microbicidal effects within the biofilm and antibiofilm concentration was the same for each microorganism. Conclusion. The stabilized HOCl solution had dose-dependent favorable effects on fibroblast and keratinocyte migration compared to povidone iodine and media alone. These features lead to a stabilized HOCl solution as an ideal wound care agent.

ABSTRACT

Background: Acne vulgaris is a common inflammatory disease of the pilosebaceous follicle that affects many teenagers and young people. There is an obvious need for topical treatments with good tolerability and efficacy for the management of acne lesions.

Objective: This study determined the therapeutic efficacy of topical sodium hypochlorite solution (0.005%) in the treatment of mild to moderate acne lesions.

Methods: This placebo-controlled randomized controlled trial compared 0.005% sodium hypochlorite to placebo administered topically on each side of the patients’ faces 3 times a day for 1 month. The numbers of papules and pustules were recorded at baseline, 1, 2 and 4 weeks after initiation.

Results: The total number of papules and pustules decreased after topical application of sodium hypochlorite 0.005% for 1 month.

Conclusions: Topical sodium hypochlorite solution (0.005%) can be effective in the treatment of mild to moderate acne, and its clinical efficacy was evaluated between the male and female groups and between the hormonal and non-hormonal ones.

Trial registration: Our study was registered in the Iranian Registry of Clinical Trials (IRCT) with the code number IRCT20200701047976N1.
