Royal Wounds Episode 2: Napoleon, Boots and the Truth About Pressure Ulcers

Dr. G explores how unrelieved pressure — not just diabetes or infection — can destroy tissue, using Napoleon Bonaparte’s chronic foot pain, stiff military boots, and relentless marching as a historical case study. The episode explains how tight footwear, prolonged weight-bearing, cold, and vascular compromise lead to ischemia and pressure ulcers, and why pain, calluses, and blisters are important warning signs.The clinical takeaway: offloading is not optional — it’s treatment. Dr. G outlines modern management steps (assessment, offloading, pressure mapping, vascular referral, custom orthotics, and physical therapy) and shows that wound care requires whole-body thinking, not just local fixes.

Klebsiella in the Wound: The Capsule Cancer Threat to Diabetic Feet

This episode of Diabetic Foot Files focuses on Klebsiella pneumoniae as an emerging and dangerous pathogen in diabetic foot ulcers, highlighting its capsule, biofilm formation, and rising antimicrobial resistance.It covers clinical presentation, the importance of deep tissue cultures, diagnostic tips, and a three-pronged treatment approach: source control (debridement), mechanical offloading, and targeted antimicrobial therapy with infectious disease involvement for ESBL or carbapenem-resistant strains.The episode also reviews prevention strategies, the role of vascular assessment, and current research directions including anti-biofilm approaches and adjunctive therapies.

Royal Wounds Series : Was King Henry VIII Diabetic?

In this episode of Diabetic Foot Files Dr. G opens the mini-series "Royal Wounds" by asking whether King Henry VIII’s notorious, years-long lower-leg wounds were due to diabetes, venous disease, or a mixed cause. Using historical accounts of his obesity, post-jousting trauma, chronic swelling, foul drainage, and fluctuating pain, the episode argues that his wounds most closely match chronic venous or mixed-etiology ulcers worsened by metabolic dysfunction.The episode also outlines how modern clinicians would evaluate and treat such wounds—vascular studies, glucose control, compression, debridement, and multidisciplinary care—and emphasizes that correct diagnosis, not status or money, is what heals chronic wounds.

Triple Clear HF with Dr. Andronica Handie, DPM, MS - Nanotech Nails: A New Front in Diabetic Foot Care

Dr. G interviews Dr. Andronica Handie, DPM, MS about combining his background in nuclear medicine and biopharmaceutical sciences with podiatric innovation to tackle onychomycosis in diabetic patients. They discuss TripleClear HF, an all‑natural topical antifungal using nanotechnology to penetrate nail plates, trial results showing marked reductions in nail thickness, and safety advantages over systemic antifungals.
Takeaways: TripleClear HF can be used preventively or as primary therapy to reduce fungal burden, improve compliance through rapid visible effects, and may play a role in long‑term diabetic foot hygiene and limb preservation alongside blood sugar control and daily foot checks.

The Silent Finisher: Morganella in Diabetic Foot Ulcers

Dr. G breaks down Morganella morganii — a gram-negative, urease-producing opportunist that appears in late-stage diabetic foot ulcers when tissue is necrotic, hypoxic, and antibiotic-weakened.The episode covers its origin, why it thrives in alkaline, chronic wounds, typical clinical signs, diagnostic pitfalls in polymicrobial cultures, intrinsic resistances (eg, ampicillin), treatment priorities like deep cultures, targeted antibiotics, aggressive debridement, and vascular assessment.

Stenotrophomonas Maltophilia in Diabetic Foot Ulcers

Episode decoding Stenotrophomonas maltophilia — a water-associated, multi-drug resistant bacterium that thrives in hospital plumbing and chronic diabetic foot ulcers. Learn how it forms biofilm, resists many antibiotics, and presents as a chronic non-healing wound that often requires targeted therapy (trimethoprim-sulfamethoxazole), aggressive debridement, and ecosystem-based care.We cover reservoirs and transmission, diagnostic tips (deep tissue culture, susceptibility testing), prevention strategies (sterile irrigation, avoid unnecessary broad-spectrum antibiotics, moisture control, early culturing) and why this quiet organism is a marker of chronicity and limb-threatening risk.

The Shape-Shifters of Diabetic Feet: Proteus mirabilis & vulgaris Unveiled

Dr. G dives into the Proteus genus—Proteus mirabilis and Proteus vulgaris—explaining their history, swarming behavior, urease-driven alkalinization, virulence factors, and why diabetic foot ulcers provide the perfect environment for these pathogens.The episode covers clinical clues (strong ammonia odor), diagnostic differences, biofilm-driven resistance, treatment priorities (sharp debridement, systemic antibiotics, pH control, and topical agents), and case examples including osteomyelitis and crystal formation.

The Red Invader: Serratia marcescens and Diabetic Foot Ulcers

In this episode of Diabetic Foot Files we explore Serratia marcescens — a red-pigment producing, opportunistic gram-negative bacterium that can rapidly worsen diabetic foot ulcers. We cover its history, microbiology and virulence, clinical clues (including the telltale pink drainage on dressings), diagnostic tips, and culture-directed treatment strategies.The episode also reviews wound care approaches to disrupt biofilm, antibiotic options guided by sensitivities, prevention steps for clinics and patients, and real-world case examples to help clinicians protect limbs and improve outcomes.

Levine vs Essen: The Right Way to Swab Diabetic Foot Ulcers

Dr. D breaks down two standardized swab techniques—the Levine and the Essen rotary methods—and explains why proper wound cleansing and pressure-based sampling are critical to getting accurate cultures. Learn step-by-step instructions, common mistakes to avoid, and when to use each method for diabetic foot ulcers.This episode highlights evidence comparing each technique to deep tissue biopsy, real clinical case examples, and practical tips to reduce false negatives, detect anaerobes, and improve patient outcomes.

BKA Explained: Surgery, Choices, Rehab & What Comes Next

In this episode of Diabetic Foot Files we walk through below‑knee amputation (BKA): why it’s performed, how surgeons select the level, and the step‑by‑step surgical technique including flap design, vascular and nerve management, and bone handling.We discuss risks of delaying surgery, post‑op care and staged rehabilitation, pain and phantom limb strategies, and the key questions patients and families should ask when facing a BKA.Clinically accurate, compassionate, and practical—this episode helps patients and caregivers understand when BKA can be life‑saving and how to prepare for recovery and return to function.
