When Missing Toes Burn: Phantom Limb Pain in Diabetic Amputees
17/2/2026 | 24 min
Dr. G explores phantom limb pain in amputees—what it feels like, how it differs from residual stump pain, and the multi-level mechanisms (peripheral nerves, spinal cord, brain prediction errors) that cause it. Special focus is given to why diabetic patients are especially vulnerable.

The episode outlines clinical evaluation, red flags to rule out, and a practical, multidisciplinary care plan including mirror therapy, graded motor imagery, neuromodulation, targeted nerve surgery, and when to refer to specialists.
Marjolin's Ulcer: When a Chronic Wound Turns Cancerous
12/2/2026 | 11 min
Dr. G explains Marjolin ulcer, a form of squamous cell carcinoma that can arise in long-standing, chronically inflamed or scarred wounds—especially diabetic foot ulcers—and why early recognition matters for limb salvage and survival.

Key signs include changing or hypertrophic margins, rolled or friable edges, unexplained bleeding, disproportionate pain, non-healing despite treatment, and nearby enlarged lymph nodes. Diagnosis requires a deep biopsy and imaging; treatment often involves wide surgical excision, possible lymph node assessment, and sometimes amputation or adjunct radiation.

Prevention and vigilance are crucial: optimize diabetes and vascular care, monitor chronic wounds closely, and refer promptly for suspicious changes. Emerging research on biomarkers, targeted therapies, and AI imaging aims to detect malignant transformation earlier.
Radiation Dermatitis Explained: How X‑Rays Damage Skin and What to Do
11/2/2026 | 8 min
This episode reviews radiation dermatitis — its history, how ionizing radiation creates free radicals and double‑strand DNA breaks, and which skin cells are damaged (basal stem cells, keratinocytes, endothelial cells, fibroblasts, lymphatics), leading to microvascular loss, fibrosis, and impaired healing.

Learn how radiation wounds present (geometric borders, fibrosis, poor bleeding, delayed healing), the typical timelines from acute to chronic changes, and why patients with diabetes are at much higher risk for chronic ulcers and complications.

Practical steps covered include gentle wound care and moisture balance, topical antimicrobials, hyperbaric oxygen for selected cases, avoiding aggressive early debridement, and when surgical reconstruction is indicated; plus prevention tips like skin moisturization, avoiding friction, and early wound surveillance.
When Ulcers Lie: Unmasking Vasculitis in the Diabetic Foot
09/2/2026 | 13 min
This episode breaks down uncontrolled vasculitis — inflammation of blood vessels that can mimic diabetic, arterial, or pressure ulcers. It reviews pathophysiology (immune complex and ANCA‑mediated mechanisms), types by vessel size, key signs (palpable purpura, necrotic toes, sudden ischemia), and essential diagnostics (ESR/CRP, ANCA, complement, urinalysis, biopsy, CTA).

It highlights urgent management (high‑dose steroids, immunosuppressants, biologics), wound‑care cautions (avoid unnecessary debridement in ischemic vasculitic ulcers), and the importance of early vascular and autoimmune referral to prevent organ damage and amputation.
Vitamin B5: The Hidden Fuel for Wound Healing
08/2/2026 | 11 min
Dr. G explains how pantothenic acid (vitamin B5) serves as the precursor to coenzyme A and powers cellular metabolism essential for wound healing, collagen and lipid synthesis, and skin barrier repair.

The episode reviews dietary sources, signs of deficiency, the topical provitamin dexpanthenol and its effects on hydration and barrier recovery, and how B5 fits into a broader approach to improving tissue regeneration in patients with high wound‑healing needs.
