Diabetic Foot Files

In this episode of Limb Watch Series with Diabetic Foot Files, host interviews Jason Ayers, a wound care RN and inventor of a topical oxygen hydrotherapy kit that combines warmed antimicrobial cleansing solution with localized oxygen bubbles to cleanse and promote healing in chronic wounds, especially diabetic foot ulcers. Jason explains the origin and prototype development, demonstrates a typical 10–15 minute treatment session, and shares case-study results showing faster cleansing, improved tissue color, reduced drainage and odor, and positive patient feedback. The discussion covers how the device fits into current debridement tools, safety and infection-control design choices, and the inventor’s vision for broader clinical adoption and training to help prevent amputations and advance limb preservation.

In this episode of Diabetic Foot Files Dr. G explores the overlooked foot–liver connection: how liver metabolism, protein synthesis, clotting, and inflammation influence wound healing, infection risk, and limb salvage in people with diabetes. Topics include metabolic dysfunction-associated steatotic liver disease (MASLD), low albumin, sarcopenia, key labs and imaging to consider, and practical steps clinicians can take to address systemic contributors to delayed healing. Takeaway: diabetic foot ulcers are rarely just a local problem—optimizing liver health, nutrition, glycemic control, and systemic care improves healing and reduces amputation risk.

This episode traces coffee’s journey and asks whether daily caffeine affects diabetic foot ulcer healing. It summarizes the science on how caffeine influences blood vessels, sleep, blood sugar, inflammation, fibroblasts, and hydration, and explains that moderate, unsweetened coffee is unlikely to severely impair healing while excessive intake, sugary drinks, poor sleep, or circulation issues can hinder recovery. Practical advice is given: consult your doctor or nutritionist, prioritize overall wound care (circulation, glycemic control, nutrition, sleep, hydration), and consider alternatives like green or herbal teas when appropriate.

Dr. G outlines simple, practical tips to prevent common Independence Day emergencies for people with diabetes, covering barefoot risks, fireworks and grill burns, blisters that become ulcers, blood sugar swings, heat dehydration, falls, and medication safety. Check your feet before and after activities, wear protective closed-toe shoes, monitor glucose frequently, stay hydrated, and seek medical care early for any wounds or burns to avoid serious infection or limb loss.

In this episode of Diabetic Foot Files Dr. G explains why surgical margins in diabetic foot surgery — especially with osteomyelitis — directly affect recurrence, healing, and the risk of further amputation. She covers the difference between positive and negative margins, how pathology and imaging guide management, and how margin status influences antibiotics, reoperation, and prognosis. Practical steps to improve margin status are discussed, including thorough debridement to bleeding bone, preoperative imaging and vascular assessment, offloading, and close coordination with infectious disease. Key takeaway: achieving negative margins greatly increases healing odds, while residual infected bone significantly raises recurrence and higher-level amputation risk.

Dr. G interviews Dr. Dawn Franceschina, a physical therapist and Vice Chair of the ABWM Foundation, about her 29-year career in wound care, advances in treatment, and the importance of Wound Healing Awareness Month. The episode highlights the PT perspective, interdisciplinary limb-salvage teamwork, board certification, common barriers to healing, and practical steps for clinicians, patients, and industry to get involved.

This episode explores how diabetic foot ulcers affect not just health but work and identity. Dr. G explains common patient fears about income, insurance, and being seen as unreliable, and how employers usually evaluate function, safety, and attendance rather than diagnosis alone. Learn practical advice on medical documentation, workplace accommodations, timing of work restrictions, and the importance of clear communication to protect both the patient’s health and long-term employment.

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.

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.

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.

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.

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.

In this episode of Diabetic Foot Files, Dr. G explores Zaynich (cefepime + ZD-bactam), a newly FDA-approved IV antibiotic designed to overcome multi-drug resistant gram-negative infections. He explains the drug's dual-target mechanism, its potential role in limb salvage for severe diabetic foot infections, common side effects, dosing, current FDA indications, and when to involve infectious disease specialists. Listeners will learn why this combination may be a game-changer for difficult-to-treat infections, the importance of antibiotic stewardship, and practical considerations for use in wound care and limb salvage scenarios.

This episode explains sarcopenia—the progressive loss of skeletal muscle—and how diabetes accelerates it, increasing risk of poor mobility, delayed wound healing, and higher mortality in patients with diabetic foot ulcers. Dr. G reviews the causes (insulin resistance, inflammation, ubiquitin–proteasome activity), clinical signs and tests, and practical treatments including resistance training, protein/leucine supplementation, vitamin D, and tighter glycemic control to preserve muscle and improve outcomes.

This episode explains the Masquelet (induced membrane) technique — a two-stage reconstructive approach where infected bone is removed, an antibiotic-loaded PMMA spacer is placed to control infection and induce a vascular membrane, and weeks later the spacer is removed and the membrane-filled cavity is packed with bone graft to regenerate bone. We cover the science of the induced membrane, antibiotic selection, how diabetes and poor blood flow affect membrane quality, and the technique's role and limitations in diabetic limb salvage.

This episode explains ecthyma gangrenosum: a rapidly evolving, black necrotic skin lesion most classically caused by Pseudomonas aeruginosa invading blood vessels. It covers the pathophysiology, stages of progression, risk factors (immunocompromise, neutropenia, diabetes), and how it differs from ordinary diabetic foot ulcers. Key takeaways: urgent tissue biopsy and cultures for diagnosis, prompt broad-spectrum IV antibiotics and surgical debridement for source control, and early recognition to prevent sepsis, limb loss, and death.

A patient with a presumed infected diabetic foot ulcer worsens after debridement and escalating antibiotics. This episode explores pathergy — an exaggerated inflammatory response to minor trauma that can mimic infection — and how misdiagnosis leads to harmful over-treatment. Learn how to recognize red flags (rapid enlargement after intervention, pain out of proportion, violaceous borders, negative cultures) and why management often requires restraint, anti-inflammatory therapy, and targeted immunomodulation rather than repeated surgical debridement.

In this episode of Diabetic Foot Files Dr. G uses Plato's allegory of the cave to reveal how long‑standing assumptions and systemic failures—not just biology—drive many diabetes‑related amputations. He highlights delayed referrals, missed vascular assessments, poor offloading, and fragmented care as the real drivers behind the shadow of inevitability. Featuring the work of limb‑salvage pioneers,  the episode stresses that diabetic foot ulcers are medical emergencies where early detection, timely revascularization, aggressive offloading, and multidisciplinary teams can prevent many amputations. It’s a call to shift from reactive care to coordinated prevention so every limb has a chance.

This episode traces how phenytoin — an anticonvulsant known for causing gingival overgrowth — was repurposed into a topical therapy for chronic wounds. It outlines the drug’s mechanisms in wounds: activating fibroblasts, increasing collagen synthesis, reducing MMP activity, modulating inflammation, and promoting granulation and angiogenesis in stalled diabetic foot ulcers. Listeners will hear clinical implications, common formulations, and important cautions: topical phenytoin can aid healing in selected chronic ulcers but does not replace debridement, offloading, vascular optimization, or infection control, and should be avoided in malignant wounds, untreated osteomyelitis, or critical ischemia. The episode also highlights the drug’s history and future delivery innovations.

This episode explores the rare Buruli (Buruli) ulcer caused by Mycobacterium ulcerans and its toxin mycolactone, which destroys tissue, suppresses immune signaling, and reduces pain, leading to delayed diagnosis and severe disability. It draws parallels with diabetic foot ulcers—both can progress silently beneath the skin—covers history, pathology, diagnosis (PCR, biopsy), treatment (antibiotics and surgery), and the key lesson: lack of pain does not mean lack of severity.

In this episode Dr. G explains why 0.9% sterile saline is the preferred when using to cleanse   for diabetic foot ulcers, diving into osmosis, isotonicity, and how saline preserves cell function while avoiding tissue damage. Why we use saline, why tap water is controversial and what alternatives really do.  Dr G also covers the risks of seawater and tap water (including dangerous bacteria like Vibrio vulnificus and piped biofilms), when advanced cleansers such as hypochlorous acid are needed, and practical takeaways: avoid ocean and non-sterile water, use isotonic sterile saline or recommended wound cleansers.

This episode explains traumatic dressing selection for diabetic wounds, emphasizing atraumatic (especially silicone-based) dressings that protect fragile peri-wound skin, preserve keratinocytes and capillaries, reduce inflammation and pain, and prevent re-injury during dressing removal. It covers risk assessment, dressing types and indications, contraindications, practical tips for removal and frequency, and the clinical importance of matching dressing choice to exudate and patient needs to support healing and avoid complications.

Dr. G explains why skin closure in diabetic foot ulcers is a transition, not a cure: the remodeling phase can last months to years, leaving the scar biologically weaker and at high risk of recurrence. He describes why peeling and color changes are often normal and how tensile strength gradually improves over time. The episode offers concise, practical guidance — daily foot checks, pressure offloading and appropriate footwear, gentle cleansing and moisturization, blood-sugar control, and multidisciplinary follow-up — to reduce re-ulceration and keep healed feet in remission.

In this episode of Diabetic Foot Files Dr. G explores pentoxifylline — a decades-old methylxanthine drug — and how it improves microcirculation, reduces blood viscosity and inflammation, and may support healing in diabetic foot ulcers, venous leg ulcers, and intermittent claudication. The episode reviews the drug’s history, mechanisms of action, clinical uses, dosing considerations, side effects, and how pentoxifylline fits into modern multimodal limb salvage and wound care strategies.

This episode explains how chronic dehydration—often overlooked in diabetic patients—slows blood flow, reduces oxygen and nutrient delivery, and stalls cellular repair, turning otherwise manageable foot ulcers into non-healing wounds. Dr. G outlines clinical signs, lab clues, and practical steps to restore hydration and improve wound healing, emphasizing that treating the whole patient — not just the wound — can produce dramatic recoveries.

This episode explains what Vaseline (petroleum jelly) does: it is an occlusive that seals moisture in but does not hydrate. It can soften intact dry skin but is unsafe for diabetic ulcers, macerated or infected areas, and interdigital spaces because it traps bacteria and oxygen, worsening wounds. The host recommends safer options for diabetic feet—urea creams, ceramide- or glycerin-based lotions, and barrier creams like zinc oxide when appropriate—and stresses daily foot inspection and early medical care rather than self-medicating with petroleum jelly.

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.

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.

On this episode of Salvage Saturdays, Dr. G explores extracorporeal shockwave therapy — the use of focused sound waves to stimulate healing in diabetic foot ulcers. We review its history from lithotripsy to orthopedics, how mechanical energy triggers angiogenesis, collagen remodeling, stem cell activation, and reduces chronic inflammation. The episode explains treatment types, energy settings, typical protocols, contraindications, and the patient experience, and emphasizes that shockwave therapy is an adjunct to standard wound care (debridement, offloading, infection control, vascular optimization). Research is promising but varied; combined regenerative approaches and larger trials are likely next steps. A case study demonstrates meaningful wound improvement with focused low-energy shockwave therapy as part of comprehensive limb salvage care.

Case study of a 58-year-old man with uncontrolled type 2 diabetes (A1C 12.4) who developed a rapidly progressive left foot ulcer after stepping on a nail. Despite antibiotics, the wound became black, necrotic, and septic; labs showed DKA and elevated inflammatory markers. MRI and tissue biopsy revealed deep angioinvasive fungal infection with broad, ribbon-like non-septate hyphae consistent with mucormycosis. Management required urgent surgical debridement, antifungal therapy (liposomal amphotericin B), metabolic stabilization, and often limb-sparing or amputation procedures; early recognition is critical due to rapid vascular invasion and high mortality.

This episode explains how and why skin flaps die, focusing on the early warning signs, differences between arterial insufficiency and venous congestion, and the underlying microvascular physiology. It covers common causes of flap failure—tension, hematoma, infection, diabetes-related microangiopathy, and poor offloading—how to assess a threatened flap (color, capillary refill, temperature, Doppler), and the step-by-step rescue measures clinicians use to improve perfusion. Listen for practical timelines for salvage, prevention strategies before surgery (vascular testing, optimization, smoking cessation, nutrition), and the importance of rapid action and frequent monitoring to maximize flap survival and protect the limb.

In this episode we introduce "Save the Fascia," a clear, stepwise mnemonic to help clinicians recognize necrotizing fasciitis early and act urgently. It outlines warning signs, diagnostic steps, and the rapid escalation needed for a time-sensitive surgical emergency. The episode emphasizes tracking progression, immediate wound management, broad-spectrum antibiotics, and early surgical consultation to improve limb salvage and survival.

Dr. G examines how the phrase "medically stable for discharge" is often misapplied to diabetic foot patients, sometimes with dangerous consequences. He explains why diabetic foot infections can be deceptively quiet, reviews warning signs like gas in tissue and abscesses, and outlines when discharge is and isn’t appropriate. The episode stresses the need for specialist input, proper imaging, source control, clear outpatient plans, and patient advocacy to prevent missed limb‑threatening emergencies and improve outcomes.

Dr. G explains why the simple incentive spirometer is more than a bedside toy: it forces deep breaths, prevents atelectasis, improves oxygenation, and reduces post-operative pulmonary complications. The episode outlines the typical post-op timeline (0–24 hrs, 24–72 hrs, 3–5 days), how poor lung expansion harms wound healing—especially in diabetic foot patients—and how spirometry links breathing to overall recovery.

In this episode of Diabetic Foot Files, Dr. G explores why seemingly small or clean-looking wounds—especially in diabetic patients—can hide severe underlying damage from retained plant matter and contamination. Learn how organic debris promotes infection, why imaging may miss wooden or thorn fragments, and the importance of exploration, serial debridement, and appropriate antibiotics. The episode reviews the Gustilo wound classification, practical management steps for different contamination levels, and imaging tips to avoid missing retained foreign bodies or necrotizing infections. Key takeaways: never primarily close contaminated wounds, antibiotics don’t replace debridement, and maintain high suspicion for gas-forming and rapidly progressive infections.

In this episode of Diabetic Flip Files’ Limb Watch, host Dr. G interviews Dr. Matthew Garoufalis , a leader in podiatric medicine, wound care and limb salvage, about the evolution of wound care into limb salvage and the science behind topical (intermittent) oxygen therapy. He is the Chief Medical Officer at Advanced Oxygen Therapy Inc.  They discuss how oxygen affects infection control, angiogenesis, collagen synthesis and cellular metabolism; clinical evidence supporting topical oxygen for diabetic foot and other wounds; practical use as an adjunctive therapy; and how optimization of oxygen can preserve tissue and reduce amputations.

In this episode Dr. G launches the Limb Watch movement and interviews Dr. Haywan Chiu, DPM, FACFAS. Board- certified in foot surgery and reconstructive rearfoot/ankle surgery. As a leading expert in diabetic limb salvage, Dr. Chiu is dedicated to preventing lower extremity amputations through innovative surgical techniques and advanced wound care management. They discuss the philosophy of limb preservation, clinical signs that predict limb loss, and when to operate or involve vascular surgery. Dr. Chiu shares advanced techniques (flaps, tendon balancing, reconstructive options), the importance of source control, pitfalls of delayed referral, practical outpatient decisions, and prevention strategies to preserve mobility and quality of life.

Dr. G examines how normal fibroblasts drive tissue repair and how, in diabetic foot ulcers, they can become senescent “zombie” cells that stop dividing, secrete inflammatory SASP factors, and degrade the wound environment. The episode covers triggers (hyperglycemia, oxidative stress, ischemia, infection), clinical signs and biomarkers of senescence, the vicious cycle with biofilm, and emerging approaches—including senolytics, targeted dressings, and debridement—to reduce senescent burden and improve healing.

This episode proposes the "Diabetic Foot Village" — a coordinated multi-sector surveillance and response model that shifts care from late-stage hospital interventions to early prevention and continuous monitoring. The framework connects a clinical core team, footwear and rehab supports, surveillance technology, and trained community touchpoints (nail techs, pharmacists, caregivers) with a national risk registry, rapid referral pathways, and home monitoring to catch problems earlier. Goals include reducing preventable amputations, lowering costs, improving limb salvage and equity in underserved areas — inspired by a patient story that highlights why shared, community-driven detection matters.

In this episode Dr. G introduces Limb Watch, a simple framework to recognize early warning signs of diabetic foot disease before they become emergencies. She explains why small changes—warmth, redness, odor, swelling, drainage, pain changes or glucose instability—matter, and how a universal alert system (green, yellow, orange, red) can prompt faster intervention and prevent amputations. Limb Watch is designed for everyone—patients, caregivers, nurses, podiatrists, nail technicians and communities—and calls for better education, surveillance, and shared accountability to preserve limbs through earlier recognition and timely action.

This episode compares tuberculosis control strategies to diabetic foot ulcer care, showing how a public-health system transformed TB from a deadly epidemic into a controllable disease and how similar systems can prevent avoidable amputations in people with diabetes. Dr. G explains key parallels—latent progression, unequal burden, and the need for engineered compliance—and proposes practical lessons: standardized screening, mandatory referral pathways, remote monitoring, multidisciplinary teams, and a national diabetic foot surveillance system to catch problems early and reduce preventable limb loss.
