Diabetes and Disability Series- Part 1 : Do I Qualify & How Long Will I Be Out of Work
28/06/2026 | 24 min
Dr. G dives into the complex reality of disability for people with diabetic foot ulcers — explaining why a diagnosis alone doesn’t determine disability, how occupation, ulcer characteristics, infection, blood flow, blood sugar, pressure, offloading, nutrition, and smoking affect healing, and why return-to-work decisions focus on function rather than timelines.
This episode emphasizes empathetic communication, accurate documentation, realistic expectations, and the difference between temporary and permanent disability, offering a clear view of why healing varies and how clinicians and patients can work together toward recovery.
Rewind the Journey: The Preventability Index in Diabetic Limb Salvage
27/06/2026 | 19 min
Dr. G explores the "Preventability Index," a framework for replaying a patients timeline to identify missed opportunities that could have prevented a diabetic foot ulcer or amputation. He explains the five domains of the index—structural deformity, skin integrity, infection burden, vascular reserve, and time to intervene—each scored 010; higher totals indicate greater preventability.
The episode emphasizes prevention through early detection, foot exams during routine visits, patient education, timely vascular and infection evaluation, and offloading. Dr. G stresses that the index is not for blame but for quality improvement and patient advocacy to reduce avoidable limb loss.
Forgotten Infection Friday — Nocardia: The Weakly Acid‑Fast Impostor
26/06/2026 | 24 min
A 62-year-old man with poorly controlled diabetes presented with weeks of cough, weight loss, night sweats, and cavitary lung lesions initially suspected to be tuberculosis or malignancy. Sputum TB tests were negative and symptoms progressed.
Bronchoscopic lung biopsy showed branching gram‑positive filaments that were weakly acid‑fast, consistent with Nocardia species. Nocardia commonly infects immunocompromised hosts, can disseminate to the brain, and is often mistaken for TB, fungal infection, or cancer. Diagnosis relies on modified acid‑fast stain, prolonged cultures, or molecular testing.
Treatment requires prolonged antibiotic therapy (commonly TMP‑SMX), sometimes IV agents for severe disease, and early recognition in diabetic or immunosuppressed patients is critical to prevent dissemination.
The Hair Test One of the Simplest Clues in Limb Salvage
25/06/2026 | 18 min
Imagine a patient with no complaints whose foot hair has vanished. This episode explains the "hair test"—how absent hair on the toes and feet can be an early bedside clue to poor circulation, peripheral arterial disease, and limb-threatening ischemia in people with diabetes.
It reviews hair follicle biology, how reduced blood flow interrupts hair growth, associated skin and nail changes, limitations of the sign (aging, genetics, friction, shaving), and practical next steps including pulse exam, Doppler, ABI/toe pressures, and vascular referral. Hair is a quick clue, not a diagnosis.
Nystatin Uncovered: Why It Heals Some Foot Fungi and Fails Others
24/06/2026 | 20 min
This episode of Diabetic Foot Files dives into nystatin: its history, how it kills Candida, and why it often works for moist, macerated toe-web infections but fails against dermatophyte-caused athlete's foot.
Dr. G explains the importance of delivery method (powder vs. cream/ointment), diabetic risk factors like moisture and hyperglycemia, and practical prevention tips for patients.
The episode also covers real-world issues such as supply shortages and cost, plus effective OTC alternatives and when to seek professional evaluation.

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.LIMBWatch: Surveillance Before Salvage.
