Edge Trenching: Turning a Wound’s Cliff into a Healing Ramp
07/25/2026 | 21 mins.
This episode introduces edge trenching, a novel debridement technique developed by Dr. Igor Melnichuk that targets dysfunctional wound edges (epibolies, hyperkeratosis, rolled or fibrotic margins) to create a biologically active transition zone and promote epithelial migration.

It explains the procedure, proposed mechanisms, clinical use—especially in diabetic plantar ulcers—how trenches are created and repeated, and emphasizes that edge trenching must be part of comprehensive care addressing perfusion, infection control, offloading, and underlying causes.
Vascular Insights with Dr. Giulia Baldazzi MD, vascular surgery fellow and PhD candidate from Italy 🇮🇹: Healing begins with circulation
07/24/2026 | 33 mins.
Dr. Giulia Baldazzi, a vascular surgeon, fellow and phd candidate researcher, shares her journey from UCSF to Italy and explores advances in perfusion assessment, revascularization, and limb preservation for diabetic foot care.

She discusses diagnostic innovations (PAT, MaxCORE, NIRS), the importance of early vascular referral and multidisciplinary teams, and practical strategies to prevent amputations and improve healing.
Forgotten Infection Friday- The Great Pretender: Actinomycosis Masquerading as Diabetic Foot Infection
07/24/2026 | 22 mins.
Actinomycosis is a rare, slow-growing filamentous gram-positive bacterial infection that can mimic cancer, tuberculosis, or chronic diabetic foot infections by producing woody fibrosis, interconnected sinus tracts, and characteristic yellow "sulfur" granules.

Diagnosis requires deep tissue biopsy and careful anaerobic culture or histology; treatment is prolonged high‑dose penicillin (or alternatives if allergic) often combined with surgical drainage and debridement.
Liquid Biopsies: The Future of Diabetic Foot Care
07/23/2026 | 9 mins.
In this episode of Diabetics with Files, Dr. G explains liquid biopsies — blood tests that detect cell-free DNA and other molecular signals — and how they work.

We explore how this technology could help detect infection early, identify harmful inflammation, predict a wound’s healing potential, and personalize treatment for diabetic foot ulcers.

The episode also covers current limitations — cost, access, standardization, and need for clinical validation — and explains that liquid biopsies would complement, not replace, clinical exams and imaging.

Ultimately, liquid biopsies could shift wound care from reactive to predictive and improve limb salvage in the future.
Exudative tax- When Wounds Become Protein Vampires: The Hidden Drain
07/22/2026 | 13 mins.
This episode explains how chronic wounds—especially heavily exudative and diabetic ulcers—act like metabolic drains, leaking proteins, growth factors, immune cells, electrolytes, and calories and impairing the body’ s ability to heal.

Listen for signs of protein loss (low albumin, persistent drainage, weight/muscle loss, delayed healing) and practical strategies to fight back: infection control, offloading, appropriate compression, nutrition optimization, and closing the wound to stop the ongoing resource loss.
