Diabetic Foot Files

This episode breaks down the neurological exam of the diabetic foot, explaining reflexes, vibration testing, monofilament assessment, proprioception, pinprick and temperature testing, and the autonomic changes that lead to dry skin and fissures.

It shows how different nerve fibers produce paradoxical symptoms, why loss of protective sensation causes silent injuries and ulcers, and why podiatry, vascular assessment and offloading are essential for limb preservation.

This episode explains what to do if you have a diabetic foot ulcer and no health insurance, stressing that you should not ignore the wound or try to self-treat. It covers signs of infection, the need for vascular checks and offloading, and when to seek emergency care.

It also outlines practical options for uninsured patients—community health centers, sliding-fee clinics, hospital charity care—and simple home measures to protect the foot while you arrange professional evaluation.

This episode explores SMAPs — synthetic mimics of antimicrobial peptides — and how they use membrane-targeting chemistry to kill bacteria differently from conventional antibiotics.

It covers the science behind facial amphiphilicity, selectivity versus toxicity, challenges like biofilms and stability, and the potential role of SMAPs as future adjunctive topical therapies for diabetic foot ulcers, while emphasizing they remain experimental and not yet clinical standard of care.

🎙️ Diabetic Foot Files: Limb Watch with Dr. Shilpa Rajan Mulki
What if some amputations could be prevented simply by recognizing the warning signs sooner?

In this episode of Diabetic Foot Files: Limb Watch, Dr. Gabrielle sits down with Dr. Shilpa Rajan Mulki, a diabetologist and diabetic foot and wound-care specialist practicing in Nairobi, Kenya, for a powerful conversation about limb preservation, prevention, and the gaps that can stand between a patient and saving their limb.

Dr. Mulki shares her personal journey into diabetic foot care and explains why multidisciplinary treatment changed the way she approaches complex wounds. Together, they discuss the warning signs of neuropathy and peripheral arterial disease, why so many patients never receive proper foot screening, and how small missed opportunities can eventually lead to devastating complications.

The conversation goes beyond the wound itself—exploring offloading, infection and antibiotic misconceptions, nutrition, biomechanics, skin-tone differences in assessment, referral pathways, healthcare access, telemedicine, clinician education, and the importance of building multidisciplinary teams that actually work together.

Most importantly, this episode asks a bigger question:

Are we doing enough to prevent diabetic foot complications—or are we waiting until the limb is already in danger?

Dr. Mulki message is one every person living with diabetes, caregiver, nurse, physician, and healthcare professional should hear:

Look at your feet. Recognize the warning signs. Act early. Save the limb.

Because limb preservation doesn't begin in the operating room.

It begins with prevention

A man who built a global whiskey empire may have been felled not by drink or duel but by a small foot injury that turned infected. This episode examines the legend of Jack Daniel’s toe, the historical accounts of gangrene and “blood poisoning,” and what modern medicine would call sepsis.

Beyond the mystery, the episode delivers a clear medical lesson: tiny wounds can become life-threatening without prompt podiatric and vascular care. Learn why early attention to foot injuries matters and how today’s treatments could have changed the outcome.
