• 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.

• The Business of Amputations -Follow the Money: Why Hospitals Profit from Amputations

  This episode explores how healthcare reimbursement incentives make amputations far more profitable than months of limb salvage and wound care for patients with diabetic foot disease. It explains the reimbursement differences, who benefits financially, why wound care programs struggle to stay open, and practical questions patients should ask to protect their limbs.
