A Rare Case Presentation
Bilateral Gangrene of Feet Secondary to Systemic Lupus Erythematosus and Raynaud Phenomenon in an Adolescent
Systemic lupus erythematosus is an autoimmune disorder that affects several organs and systems in the human body. Digital gangrene is known to be a rare and severe complication of systemic lupus erythematosus that could lead to amputation. We report a case of an adolescent who presented with an autoimmune disorder and multiple comorbidities and developed gangrenous toes.
Motivational Interviewing by Podiatric Physicians
A Method for Improving Patient Self-care of the Diabetic Foot
Foot ulceration and lower-extremity amputation are devastating end-stage complications of diabetes. Despite agreement that diabetic foot self-care is a key factor in prevention of ulcers and amputation, there has only been limited success in influencing these behaviors among patients with diabetes. While most efforts have focused on increasing patient knowledge, knowledge and behavior are poorly correlated. Knowledge is necessary but rarely sufficient for behavior change. A key determinant to adherence to self-care behavior is clinician counseling style. Podiatrists are the ideal providers to engage in a brief behavioral intervention with a patient. Motivational interviewing is a well-accepted, evidence-based teachable approach that enhances self-efficacy and increases intrinsic motivation for change and adherence to treatment. This article summarizes some key strategies that can be employed by podiatrists to improve foot self-care. (J Am Podiatr Med Assoc 101(1): 78–84, 2011)
Severely comminuted fractures of the metatarsal bones with significant bone and soft-tissue loss have commonly subjected patients to proximal amputation procedures. We describe two patients who experienced high-energy traumatic injuries to their limbs that resulted in significant destruction of their first and second metatarsal bones with overlying soft-tissue trauma not amenable to local coverage. In both cases, a vascularized free fibular osteocutaneous flap was used to reconstruct the metatarsal bone defect and traumatized soft tissues so that a proximal amputation was avoided. At an average of 14 months of follow-up, both patients had recovered well and regained independent ambulation, with one patient being able to play soccer. We show that the free fibular osteoseptocutaneous flap is useful in reconstructing significant metatarsal bone defects and in avoiding amputations in this patient population. The skin component of the flap may be used to fill soft-tissue losses, and the fibula bone may be osteotomized so that more than one ray may be reconstructed.

Charcot’s arthropathy is a devastating condition affecting diabetic patients with peripheral neuropathy, resulting in a foot at risk for ulceration and amputation. Early diagnosis is important for the institution of appropriate treatment, which may help prevent disease progression and foot deformity. This article discusses the pathogenesis and treatment options available for the disorder. (J Am Podiatr Med Assoc 92(7): 381-383, 2002)
Background: Diabetic foot ulcers (DFUs) are the main cause of hospitalizations and amputations in diabetic patients. Failure of standard foot care is the most important cause of impaired DFU healing. Dakin’s solution (DS) is a promising broad-spectrum bactericidal antiseptic for management of DFUs. Studies investigating the efficacy of using DS on the healing process of DFUs are scarce. Accordingly, this is the first evidence-based, randomized, controlled trial conducted to evaluate the effect of using diluted DS compared with the standard care in the management of infected DFUs.
Methods: A randomized controlled trial was conducted to assess the efficacy of DS in the management of infected DFUs. Patients were distributed randomly to the control group (DFUs irrigated with normal saline) or the intervention group (DFUs irrigated with 0.1% DS). Patients were followed for at least 24 weeks for healing, reinfection, or amputations. In vitro antimicrobial testing on DS was performed, including determination of its minimum inhibitory concentration, minimum bactericidal concentration, minimum biofilm inhibitory concentration, minimum biofilm eradication concentration, and suspension test.
Results: Replacing normal saline irrigation in DFU standard care with 0.1% DS followed by soaking the ulcer with commercial sodium hypochlorite (0.08%) after patient discharge significantly improved ulcer healing (P < .001) and decreased the number of amputations and hospitalizations (P < .001). The endpoint of death from any cause (risk ratio, 0.13; P = .029) and the amputation rate (risk ratio, 0.27; P < .001) were also significantly reduced. The effect on ulcer closure (OR, 11.9; P < .001) was significantly enhanced in comparison with the control group. Moreover, DS irrigation for inpatients significantly decreased bacterial load (P < .001). The highest values for the in-vitro analysis of DS were as follows: minimum inhibitory concentration (MIC), 1.44%; minimum bactericidal concentration (MBC), 1.44%; minimum biofilm inhibitory concentration (MBIC), 2.16%; and minimum biofilm eradication concentration (MBEC), 2.87%.
Conclusions: Compared with standard care, diluted DS (0.1%) was more effective in the management of infected DFUs. Dakin’s solution (0.1%) irrigation with debridement followed by standard care is a promising method in the management of infected DFUs.
Background:
The scope of podiatric practice has changed significantly in the past couple of decades. Despite the increased quality of training, many people outside of podiatry may not realize what our scope of practice entails.
Methods:
We conducted a survey consisting of 10 items and asked internal medicine residents at Rush University Medical Center and patients whether they would feel comfortable consulting podiatrists, or being treated for each issue.
Results:
The results for residents are as follows: 1) toenail fungus, 35% yes and 65% no; 2) diabetic wound care, 87.5% yes and 12.5% no; 3) bunion surgery, 90% yes and 10% no; 4) ankle fracture surgery, 25% yes and 75% no; 5) calcaneal fracture surgery, 50% yes and 50% no; 6) tarsal tunnel nerve surgery, 62.5% yes and 37.5% no; 7) lower extremity arterial bypass, 5% yes and 95% no; 8) below-knee amputation, 5% yes and 95% no; 9) transmetatarsal amputation, 67.5% yes and 32.5% no; and 10) venous stasis wound care, 65% yes and 35% no. The results for patients are as follows: 1) toenail fungus, 72.5% yes and 27.5% no; 2) diabetic wound care, 70% yes and 30% no; 3) bunion surgery, 62.5% yes and 37.5% no; 4) ankle fracture surgery, 57.5% yes and 42.5% no; 5) calcaneal fracture surgery, 55% yes and 45% no; 6) tarsal tunnel nerve surgery, 50% yes and 50% no; 7) lower extremity arterial bypass, 32.5% yes and 67.5% no; 8) below-knee amputation, 27.5% yes and 72.5% no; 9) transmetatarsal amputation, 52.5% yes and 47.5% no; and 10) venous stasis wound care, 32.5% yes and 67.5% no.
Conclusions:
Internal medicine residents and patients do not have an accurate perception of the scope of podiatric medicine. This proves that, as a profession, we need to raise awareness about what the podiatric scope of medicine actually entails.
Background:
We assessed the efficacy of customized foot orthotic therapy by comparing reulceration rates, minor amputation rates, and work and daily living activities before and after therapy. Peak plantar pressures and peak plantar impulses were compared with the patients not wearing and wearing their prescribed footwear.
Methods:
One hundred seventeen patients with diabetes were prescribed therapeutic insoles and footwear based on the results of a detailed biomechanical study and were followed for 2 years. All of the patients had a history of foot ulcers, but none had undergone previous orthotic therapy.
Results:
Before treatment, the reulceration rate was 79% and the amputation rate was 54%. Two years after the start of orthotic therapy, the reulceration rate was 15% and the amputation rate was 6%. Orthotic therapy reduced peak plantar pressures in patients with reulcerations and in those without (P < .05), although a significant decrease in peak plantar impulses was achieved only in patients not experiencing reulceration. Sick leave was reduced from 100% to 26%.
Conclusions:
Personalized orthotic therapy targeted at reducing plantar pressures by off-loading protects high-risk patients against reulceration. Treatment reduced the reulceration rate and peak plantar pressures, leading to patients’ return to work or other activities. (J Am Podiatr Med Assoc 103(4): 281-290, 2013)
Testing for Loss of Protective Sensation in Patients with Foot Ulceration
A Cross-sectional Study
Current recommendations for the prevention of foot ulceration and amputation include screening at-risk individuals by testing for loss of protective sensation at eight sites using 10-g (5.07) nylon monofilaments. Yet measurement of the cutaneous pressure threshold to differentiate one-point from two-point static touch stimuli may allow identification of these at-risk individuals earlier in the clinical course of diabetic neuropathy. The present study tested this hypothesis using a prospective, cross-sectional, multicenter design that included sensibility testing of 496 patients with diabetic neuropathy, 17 of whom had a history of ulceration or amputation. Considering the cutaneous pressure threshold of the 5.07 Semmes-Weinstein nylon monofilament to be equivalent to the 95 g/mm2 one-point static touch measured using the Pressure-Specified Sensory Device (Sensory Management Services LLC, Baltimore, Maryland), only 3 of these 17 patients with a history of foot ulceration or amputation would have been identified using the Semmes-Weinstein nylon monofilament screening technique. In contrast, using the Pressure-Specified Sensory Device, all 17 patients were identified as having abnormal sensibility, defined as greater than the 99% confidence limit for age, for two-point static touch on the hallux pulp. We conclude that patients at risk for foot ulceration can best be identified by actual measurement of the cutaneous sensibility of the hallux pulp. (J Am Podiatr Med Assoc 95(5): 469–474, 2005)
Neuropathy in Diabetes
Not a Knee-Jerk Diagnosis
Neuropathic symptoms in patients with diabetes occur commonly and are most often a consequence of the diabetes. Up to 10% of patients with diabetes and neuropathy have an etiology other than diabetes as a cause of their nerve dysfunction. Herein we present a case of vasculitic neuropathy initially misdiagnosed as diabetic neuropathy that led to separate amputations of two toes. This case emphasizes the importance of considering alternative, potentially treatable, causes of peripheral neuropathy in patients with diabetes. (J Am Podiatr Med Assoc 98(4): 322–325, 2008)
An Assessment of Intralesional Epidermal Growth Factor for Treating Diabetic Foot Wounds
The First Experiences in Turkey
Background:
Intralesional epidermal growth factor (EGF) has been available as a medication in Turkey since 2012. We present the results of our experience using intralesional EGF in Turkey for patients with diabetic foot wounds.
Methods:
A total of 174 patients from 25 Turkish medical centers were evaluated for this retrospective study. We recorded the data on enrolled individuals on custom-designed patient follow-up forms. Patients received intralesional injections of 75 μg of EGF three times per week and were monitored daily for adverse reactions to treatment. Patients were followed up for varying periods after termination of EGF treatments.
Results:
Median treatment duration was 4 weeks, and median frequency of EGF administration was 12 doses. Complete response (granulation tissue >75% or wound closure) was observed in 116 patients (66.7%). Wounds closed with only EGF administration in 81 patients (46.6%) and in conjunction with various surgical interventions after EGF administration in 65 patients (37.3%). Overall, 146 of the wounds (83.9%) were closed at the end of therapy. Five patients (2.9%) required major amputation. Adverse effects were reported in 97 patients (55.7%).
Conclusions:
In patients with diabetic foot ulcer who received standard care, additional intralesional EGF application after infection control provided high healing rates with low amputation rates.
