So how should I treat my patients with peripheral neuropathy???
![Page 30: I also call this lecture… · Management and Treatment of the Diabetic Foot Most podiatrists have extensive ... • Charcot Restraint Orthotic Walker (CROW boot) Charcot Gout. RED,](https://reader033.fdocuments.us/reader033/viewer/2022050410/5f870f699ae0ea5ab777fdb5/html5/thumbnails/30.jpg)
Should you work it up?
If patient is diabetic?
Usually assume DPN ~90% of PN is caused by DM
If suspicion of infectious process or nutritional deficiency, treat appropriately and symptoms may
resolve
If not diabetic, absolutely!

Peripheral Neuropathy Etiology
D – iabetes
A – lcoholism
N – utritional = Vitamin B1, B6, B12, E
G – uillan-Barre
T – oxic = Drugs, Lead, Arsenic
HE – reditary = Charcot-Marie Tooth, Refsum'sdz, Friedrich's Ataxia
R – ecurrent = Chronic inflammatory demyelinating polyneuropathy
A – myloidosis
P – orphyria
I – nfection = HIV, leprosy, mononucleosis, Lyme, diptheria, untreated syphilis
S – ystemic = Uremic syndrome, SLE, hypothyroid, Sjogren's
T – umors = paraneoplastic, multiple myeloma

Diabetic Peripheral Neuropathy
IRREVERSIBLE
Prevention = tight glycemic control
• “Intensive treatment” à increased mortality risk (ACCORD study)
HTN, hyperlipidemia, elevated BMI, and smoking MAY contribute to DPN
Clinical trials focusing on disease modification have failed because we lack knowledge on the pathophysiology of DPN

If you don’t already…
Refer to Your Favorite
Podiatrist!
l Several studies have demonstrated decreased morbidity and mortality when podiatric surgeons are involved in the care of diabetic patients with and without ulcerations
l A 2011 study demonstrated that during the 2 years following the onset of an initial DFU, podiatric care lowered the cost of treatment under commercial plans by $13,474 and by $3624 on Medicare plans.
l Podiatrists reduce hospitalizations secondary to ulcer/infection, reduce the formation of DFU's, and reduce amputation rates
l We save limbs, but also subsequently save lives per the mortality statistics previously mentioned
![Page 43: I also call this lecture… · Management and Treatment of the Diabetic Foot Most podiatrists have extensive ... • Charcot Restraint Orthotic Walker (CROW boot) Charcot Gout. RED,](https://reader033.fdocuments.us/reader033/viewer/2022050410/5f870f699ae0ea5ab777fdb5/html5/thumbnails/43.jpg)
Remember that foot ulcer ALONE increases risk of mortality in diabetic population by 37% - Do not underestimate the
morbidity and mortality of a foot ulceration
Patients with DM and one of these systemic comorbidities should see a podiatrist at least every 3 months
3. Renal disease2. CHF1. Liver disease

Look for callouses, bony deformities, or areas of irritation on every diabetic foot
Calluses with intradermal
hemorrhage may be ulcerated – Refer
immediately
Equinus increases forefoot loading
pressure, early heel off, increased shear,
prolonged stance phase
