Effectiveness of combined modulated ultrasound and electric current stimulation to treat diabetic foot ulcers

Short-term effect of dressing with Dermaheal ointment in the treatment of diabetic foot ulcer: A double-blinded randomized controlled clinical trial

Background and Aims

Diabetic foot ulcers, a major cause of amputations in diabetics, could benefit from natural products as adjuncts to standard care, given the costs and adverse effects of typical therapies. This study aims to evaluate the short-term effects of dressing with Dermaheal ointment in the treatment of DFUs through a double-blinded randomized controlled clinical trial.

Methods

This double-blinded, placebo-controlled trial included 50 patients with Wagner's ulcer grade I or II, randomly assigned to Dermaheal and placebo groups (received standard treatment and placebo ointment). The ulcer site was dressed daily for four consecutive weeks with either Dermaheal or placebo ointment. Ulcer healing score (using DFU healing checklist), ulcer size with transparent ruler and largest dimension of ulcer, and pain severity using numerical pain rating score (were recorded at five-time points, including baseline, and on weeks 1, 2, 3, and 4). Also, ulcer healing status was investigated at the trial ended in November 2021.

Results

Both groups showed significant improvement in ulcer healing over 4 weeks (p time < 0.001), with more remarkable progress in the Dermaheal group (p group = 0.03). At the trial end, complete ulcer healing was also significantly higher in the Dermaheal group compared to the placebo group (56% vs. 12%, p = 0.002). Both groups exhibited a decrease in ulcer size (p time < 0.001). Considering the baseline ulcer size as a covariate, substantial changes in mean ulcer size were noted in the initial (p = 0.01), second (p = 0.001), third (p = 0.002), and fourth (p = 0.002) weeks of the intervention, showing a preference for the Dermaheal group. However, no significant between-group difference was observed in pain severity levels.

Conclusion

Dressing with Dermaheal as a topical treatment shows promise in improving healing and reducing the size of diabetic foot ulcers. Further research is needed to confirm these findings' long-term efficacy.

Effect of ultrasound-supported wound debridement in subjects with diabetic foot ulcers: A meta-analysis

A meta-analysis study to assess the effect of ultrasound-supported wound debridement (USSD) in subjects with diabetic foot ulcer (DFU). A comprehensive literature examination till January 2023 was implemented and 1873 linked studies were appraised. The picked studies contained 577 subjects with DFUs in the studies' baseline, 282 of them were using USSD, 204 were using standard care, and 91 were using a placebo. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to calculate the consequence of USSD in subjects with DFUs by the dichotomous styles and a fixed or random effect model. The USSD applied to DFU caused a significantly higher wound healing rate compared with the standard care (OR, 3.08; 95% CI, 1.94-4.88, P < .001) with no heterogeneity (I2  = 0%) and the placebo (OR, 7.61; 95% CI, 3.11-18.63, P = .02) with no heterogeneity (I2  = 0%). The USSD applied to DFUs caused a significantly higher wound healing rate compared with the standard care and the placebo. Though precautions should be taken when commerce with the consequences as all of the picked studies for this meta-analysis was with low sample sizes.

The Potential of Electrical Stimulation and Smart Textiles for Patients with Diabetes Mellitus

Diabetes mellitus is one of the most frequent diseases in the general population. Electrical stimulation is a treatment modality based on the transmission of electrical pulses into the body that has been widely used for improving wound healing and for managing acute and chronic pain. Here, we discuss recent advancements in electroceuticals and haptic/smart devices for quality of life and present in which patients and how electrical stimulation may prove to be useful for the treatment of diabetes-related complications.
