Latest Episodes:

Don’t Miss Necrotizing Fasciitis in Diabetics also don’t miss it in anyone at all Feb 26, 2026

Show notes

Dr. G reviews necrotizing fasciitis—its history, classification, and why missed diagnosis is often fatal—especially in diabetic patients. Learn the red flags (deep pain, rapid progression, gray “dishwater” drainage), key labs (CRP >150, hyponatremia, lactate), and the LRINEC score.

This episode emphasizes rapid recognition, use of bedside ultrasound, aggressive labs and imaging, immediate surgical consultation, and early broad-spectrum IV antibiotics plus debridement—because early action saves lives.

When Your Blood Betrays You: DIC and Diabetic Foot Infections Feb 25, 2026

Show notes

In this episode of Diabetic Foot Files Dr. G explains disseminated intravascular coagulation (DIC): what it is, how severe diabetic foot infections (like necrotizing fasciitis and osteomyelitis) can trigger it, and why early recognition matters.

Learn common triggers, key lab patterns (thrombocytopenia, prolonged PT/aPTT, low fibrinogen, very high D-dimer), urgent management steps (source control, ICU care, transfusions, cautious heparin) and practical warnings to prevent escalation.

The episode stresses listening to patients, drawing timely labs, and treating the cause—because early action can mean saving a life, not just a limb.

POGO By DARCO: The Future of Diabetic Footwear Feb 23, 2026

Show notes

In this special episode of Diabetic Foot Files, host Dr. G engages in an insightful discussion with Riley Sernica, the Vice President of Product Development at Darco .Together, they explore the innovation behind the Darco Pogo shoe, a groundbreaking development in diabetic foot care designed with intentional offloading to promote healing and prevent ulceration.

Riley shares the journey from conceptualization to realization of the Pogo shoe, highlighting the significance of pressure offloading in diabetic foot ulcer management. They delve into the unique design features of the shoe, inspired by real patient stories, and discuss how it marries fashion with functionality, ensuring comfortable wear without compromising on style.

Listeners will gain insights into the impact this innovative shoe can have on patient compliance, the role of advanced materials in promoting wound healing, and Darko's vision for the future of diabetic footwear - a shoe for everyone, not just those with diabetes. This episode is a testament to the potential of fashion-driven health solutions in transforming lives.

The Foot First: How Podiatrists Spot Vascular Disease Before Anyone Else Feb 22, 2026

Show notes

This episode explains why podiatrists are often the first clinicians to detect peripheral arterial disease in diabetic patients, describing common signs—shiny skin, hair loss, delayed capillary refill, painful ulcers and nondetectable pulses—and the pathophysiology behind early ischemia.

It outlines the importance of prompt vascular referral, diagnostic tests (ABI, toe pressures, duplex), and early interventions to improve limb salvage and reduce major amputations, advocating annual vascular evaluation for people with diabetes.

Lidocaine: Not as Harmless as a Gel — What Every Wound Care Patient Should Know Feb 21, 2026

Show notes

Dr. G explains how lidocaine works, why its chemistry matters, and how too much—especially on open, inflamed, or diabetic wounds—can cause serious central nervous system and cardiac toxicity.

The episode covers safe dosing calculations, differences between wound types, safer alternatives for anesthesia, and first-aid steps if toxicity occurs, emphasizing caution and medical supervision.

Not One-Size-Fits-All: How to Use (and Avoid Misusing) the Unna Boot Feb 19, 2026

Show notes

Dr. G breaks down the Unna boot: its origin, ingredients (zinc oxide, glycerin, gelatin), and how its semi‑rigid, inelastic compression helps venous stasis ulcers. He compares Unna boots to modern multi‑layer systems, explains the pressure mechanics and therapeutic targets, and highlights practical application tips.

Key cautions are emphasized: always assess vascular status/ABI before compressing, avoid use with critical arterial disease, heavy drainage, active infection, non‑ambulatory patients, or purely neuropathic plantar ulcers. Compression must be individualized and combined with correct diagnosis and overall wound care.

Limb Salvage for All: Dr. Tom Hardiman DPM on Access, healthcare inequity , and Prevention Feb 18, 2026

Show notes

Dr. Tom Hardiman DPM draws on decades of experience in podiatry and limb salvage to reveal how systemic inequities and barriers to care drive preventable amputations in people with diabetes. He explains the social determinants of health—housing instability, food insecurity, lack of transportation—and how unequal access to vascular care, nutrition, and timely treatment leads to worse outcomes for underserved communities.

Hardiman shares personal patient stories, emphasizes the importance of patient advocacy and education, and calls for policy changes that prioritize health equity over profit to reduce the 175,000 annual amputations in the U.S. and improve limb salvage for everyone.

When Missing Toes Burn: Phantom Limb Pain in Diabetic Amputees Feb 17, 2026

Show notes

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 Feb 12, 2026

Show notes

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 Feb 11, 2026

Show notes

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.
