Welcome to the Diabetic Foot Files Podcast and the LIMBWatch series — where diabetic foot surveillance, wound intelligence, prevention science, and limb preservation come together. I’m Dr. G / Dr. WoundPicasso aka Dr. Gabrielle Hutcheson Donaldson, podiatrist and wound care specialist, and I’m here to educate, empower, and guide you through the evolving world of diabetic foot care.
From wound healing and pressure injuries to surveillance systems and amputation prevention, we break down the science, challenge the myths, and share strategies that help save limbs and improve lives. Whether you’re a patient, caregiver, clinician, or healthcare professional, this is your destination for diabetic foot education, prevention, and preservation.
So let’s dive in — because when you take care of your feet, they take care of you.

In this episode of Diabetic Foot Files — Limb Watch Edition, Stephanie Stellini Turner, a surgical physician assistant at Christiana Care, discusses the realities of reconstructive and limb salvage care. She shares OR experiences, perioperative workflows, and the teamwork needed between vascular, plastics, and wound care teams.
The conversation covers timing and techniques for reconstruction, managing complex diabetic and trauma wounds, patient optimization and prevention, and the emotional and practical challenges of guiding patients through recovery.

Dr.G explores how vitamin D — produced by sunlight and acting like a hormone — impacts diabetic foot healing. He covers its roles in immune regulation, antimicrobial peptide production, inflammation control, collagen synthesis, angiogenesis, bone health, and mood, plus why deficiency is common in people with diabetes.
The episode reviews research linking low vitamin D to worse ulcers, the potential benefits and limits of supplementation, who should be screened, and why vitamin D is one piece of a multidisciplinary approach that includes vascular care, infection control, nutrition, offloading, and mental health support.

Dr. G explains why negative pressure wound therapy (wound VAC) can cause significant pain—covering foam adherence, nerve ingrowth, inflammation, and the four types of VAC-related pain. He highlights why pain may signal complications in diabetic wounds and why neuropathy does not always mean no pain.This episode offers practical solutions: premedication, topical anesthetics, saline soaking, silicone contact layers, continuous versus intermittent modes, regional blocks, and the role of communication and monitoring to reduce suffering while preserving limb salvage.

June is Wound Healing Awareness Month (WHAM)! Join us in raising awareness, advancing education, and improving outcomes for patients with wounds—because every wound deserves the chance to heal. Celebrate Wound Healing Awareness Month (WHAM) this June with the American Board of Wound Management (ABWM) and take the next step in your wound care career with 25% off your first certification application- https://abwmcertified.org/promo/
Welcome to Wound Healing Awareness Month — a celebration of the body’s ability to repair itself and the people who make healing possible.Diabetic foot ulcers are complex and often reflect deeper issues like neuropathy, poor circulation, and immune dysfunction.
Early care, proper offloading, and teamwork among podiatrists, vascular surgeons, nurses, and caregivers improve outcomes.Sharp debridement and personalized wound treatments can unlock rapid healing when applied correctly.Nutrition, blood sugar control, and smoking cessation are essential ingredients for successful wound repair. Prevention matters — daily foot checks, proper footwear, and early attention to calluses or blisters save limbs.Emerging innovations like cellular therapy, skin substitutes, negative pressure, and AI are transforming wound care.Healing is both medical and personal — patience, trust, and caregiver support make a real difference.
Every healed limb represents a team that refused to quit and a patient who kept showing up for care. If you have a wound, seek help early — every day counts toward saving a limb and restoring life.

In this episode Dr. G explains daptomycin — a powerful cyclic lipopeptide antibiotic used for serious gram-positive infections like MRSA and VRE in diabetic foot disease. Learn how it works by depolarizing bacterial membranes, why it’s ineffective for pneumonia, and when it’s chosen over vancomycin.We cover clinical uses in osteomyelitis and limb salvage, the challenges of biofilms and resistance, key safety considerations (CPK monitoring, statin interactions, rare eosinophilic pneumonia), and why antibiotics must be paired with surgery, vascular care, and glycemic control for successful outcomes.

In this episode we follow a single drop of blood from a diabetic patient under the microscope to reveal how chronic high blood sugar alters red blood cells, white cells, platelets, plasma proteins, and the endothelium. These microscopic changes—stiffer cells, rouleaux formation, dysfunctional immune cells, increased viscosity, and inflammation—contribute to poor oxygen delivery, slow healing, infection, and complications like foot ulcers and amputations.The episode also traces the history of blood microscopy, explains mechanisms such as glycation and elevated fibrinogen, and emphasizes that improved glycemic control, infection management, vascular care, and nutrition can help restore blood function and speed healing.

This episode of Diabetic Foot Files covers chromoblastomycosis, a chronic pigmented fungal skin infection often seen in tropical, agricultural settings and commonly affecting the lower limbs.We discuss why patients with diabetes are at higher risk, the classic "copper penny" cells on pathology, common clinical features (verrucous, slow-growing lesions with black dots), diagnostic steps like biopsy and fungal stains, and treatment challenges including long-term antifungals, surgery, and wound optimization.

On this episode of Limb Watch, Dr. G speaks with Dr. Gary Rothenberg DPM, CDCES, CWS about limb preservation, diabetic foot care, wound healing, and vascular health. Dr. Rothenberg discuss the root role of neuropathy, the importance of prevention, and the power of caregivers and multidisciplinary teams.
Dr. Rothenberg explains remote temperature monitoring with the Podometrics SmartMat, shares lessons from the VA and clinical practice, and highlights practical steps to detect problems earlier and reduce amputations through education, access, and coordinated care.

In this episode of Diabetic Fit Files, Dr. G explains how topical nitroglycerin paste works as a vasodilator to improve microcirculation and rescue threatened skin flaps, ischemic digits, and compromised grafts. The episode covers its mechanism (nitric oxide release), clinical indications, historical background, and why it can help in diabetic wound care.Key clinical pearls and cautions are summarized, including when it may help, common side effects (headache, hypotension), major contraindications (concurrent PDE-5 inhibitors, severe hypotension, anemia), and why it should never replace urgent surgical intervention when needed.

This episode explains how the gut microbiome — an internal ecosystem of bacteria, fungi, and viruses — regulates inflammation, immunity, metabolism, and wound healing, and how diabetes disrupts that balance.High blood sugar, altered gut conditions, and repeated antibiotics can cause dysbiosis and leaky gut, driving chronic systemic inflammation, immune dysfunction, biofilm formation, impaired angiogenesis and collagen synthesis, and stalled diabetic wound healing.Practical approaches discussed include glycemic control, nutrition (fiber and fermented foods), targeted probiotics/prebiotics, exercise, sleep and stress management, antibiotic stewardship, and multidisciplinary care to support both the gut and the wound for better limb salvage outcomes.
