BACKGROUND: Diabetic foot ulcers are a common complication in the advanced stages of diabetes mellitus. Certain lesions may be refractory to usual treatments with prolonged healing. In these cases, differential diagnoses to classical ulcers should be considered. Although plantar warts are a common and easy-to-diagnose finding in the general population, diagnosis can be challenging in people with diabetic foot ulcers, as they mimic hyperkeratosis in these people. CASE REPORT: We report seven cases of people with diabetic foot ulcers and verrucae vulgares mimicking treatment-refractory hyperkeratosis, presenting to our centre between 2014 and 2016...

OBJECTIVE: This study aimed to validate a smart-textile based on fiber-optics for simultaneous measurement of plantar temperature, pressure, and joint angles in patients with diabetic peripheral neuropathy (DPN). METHODS: After in-vitro validation in the laboratory, 33 eligible subjects with DPN were recruited (age: 58 ± 8 years, BMI: 31.5 ± 8 kg/m(2)) for assessing plantar pressure and temperature during habitual gait-speed in a clinical-setting. All participants were asked to walk at their habitual speed while wearing a pair of sensorized socks made from highly flexible fiber optics (SmartSox)...

Since the first attempt in 1968, survival following pig-to-primate liver xenotransplantation (LXT) has been limited. We evaluated a model utilizing α-1,3-galactosyltransferase knockout donors, continuous post-transplant infusion of human prothrombin concentrate complex and immunosuppression including anti-thymocyte globulin, FK-506, methylprednisone and co-stimulation blockade (belatacept, n=3 or anti-CD40mAb, n=1) to extend survival. Baboon #1 remained well until POD25 when euthanasia was required due to cholestasis and plantar ulcers...

Foreign bodies are occasionally seen by family physicians. Plantar foreign bodies in particular pose a special challenge because they involve weight-bearing regions that are difficult to access. If left undetected long enough, these may lead to hospitalization, surgery, or even longstanding complications such as tumors, contractures, infections, and chronic ulcers. Dermoscopy of the cutaneous surface allows early detection of indwelling foreign bodies with a far greater degree of accuracy than with the naked eye...

BACKGROUND: Diabetic foot ulcers (DFU) are a major complication in diabetics. Impaired microvascular reactivity is a major contributor to the development of DFU and has been traditionally quantified by time-domain or frequency-domain measures of skin blood flow (SBF). These measures, however, are unable to characterize the changes of nonlinear dynamics of SBF associated with diabetes and peripheral neuropathy. OBJECTIVE: The objective of this study was to investigate altered nonlinear dynamics of skin blood flow in the plantar foot of diabetics with peripheral neuropathy...

Muhammad Nouman, Wipawan Leelasamran, Surapong Chatpun
BACKGROUND: Using a total contact orthosis (TCO) is an effective method to offload in diabetic patients with foot neuropathy. However, the redistribution of peak plantar pressure is mostly observed during level walking, which may differ from other walking activities. The aim of this study was to investigate the plantar pressure from 4 regions of the foot during different walking activities (level walking, ramp ascending, ramp descending, stair ascending, and stair descending) in neuropathic diabetic patients with and without a TCO...

Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living...

Worldwide, diabetic foot ulcers (DFUs) continue to exact a major burden on patients and health care providers. Although hyperbaric oxygen therapy is well-known as an adjunct option, less is known about the efficacy of transdermal continuous oxygen therapy (TCOT). A prospective, randomized, blinded, multicenter, parallel study was conducted from October 2009 to November 2012 to evaluate healing time and the proportion of DFUs healed after 12 weeks of moist wound therapy (MWT) with or without TCOT. Study participants (persons with type 1 or type 2 diabetes and a nonhealing [>1-month but <1-year duration], 1 cm² to 10 cm² in area, infection-free DFU) were randomized to TCOT or a sham device (control) in addition to receiving MWT...

Diabetic foot ulcer is a serious complication in patients with diabetes. In most outcome studies of this condition, there is a combination of various types of ulcer and ulcer locations. Plantar ulcers are usually localized to the forefoot, and constitute a quarter of all diabetic foot ulcers. There are a limited number of studies regarding development of new ulcers following healing of a plantar forefoot ulcer, and there are no uniform definitions of recurrent and other new ulcers. The aim of this study was to evaluate the outcome of a large cohort of consecutively treated patients with diabetes mellitus and a healed planter forefoot ulcer (n = 617) with regard to development, characteristics, and outcome of recurrent and other new ulcers...

Objective: Foot and ankle exercise has been advocated as a preventative approach in reducing the risk of foot ulceration. However, knowledge about the appropriate types and intensity of exercise program for diabetic foot ulcer prevention is still limited. The current study aimed to examine the effects of an eight-week mini-trampoline exercise on improving foot mobility, plantar pressure and sensation of diabetic neuropathic feet. Methods: Twenty-one people with diabetic peripheral neuropathy who had impaired sensation perception were divided into two groups...

Offloading is a cornerstone in managing diabetic plantar foot ulcers; however, it often represents one of the most challenging aspects of treatment for clinician and patient alike. The authors present a case of a 61-year-old African American man with type 2 diabetes and a limb-threatening plantar foot ulcer that required aggressive wound and surgical management. Due to the heavy drainage and patient adherence issues, traditional offloading techniques such as total contact cast, DH Pressure Relief Walker (Össur, Foothill Ranch, CA), and wedge shoes, among others, were not viable options...

Leprosy is a chronic infectious disease caused by Mycobacterium leprae. Approximately 30% of patients with leprosy develop nerve damage. Trophic, or neuropathic, ulcer is a common complication of an anesthetic foot. The term plantar, trophic, or perforating ulcer was introduced in 1959. It was defined as a chronic ulceration of the anesthetic foot, situated in well-defined areas overlying bony prominences, resistant to local and/or systemic therapy, and characterized by a marked tendency to recur. It is responsible for much of the morbidity associated with leprosy...

Prevention of serious diabetic foot complication like ulceration or infection is an important issue. As the development of thermal graphic technologies, foot temperature-guided avoidance therapy has been recommended. Doctors from Hospital National Dos de Mayo are studying on the risk of the diabetic foot passing from Grade 0 to Grade 1 in the Wagner Scale. This risk to develop ulcers is related to the temperature difference of corresponding area between left and right foot. Generally speaking, the diabetic foot with greater mean temperature difference has more potential to develop ulcers; especially, area whose temperature difference of more than 2...

Favorable results have been reported for tibialis posterior tendon transfers, which can effectively restore the dorsiflexion of the ankle and normal heel-to-toe gait. However, the commonly used methods for anchoring the transplanted tendon have some drawbacks. Therefore, we developed a new tendon-anchoring method to improve fixation of the transferred tendon and reduce the related complications. The new method entails tying the anchoring suture to the navicular bone instead of the button on the plantar foot to avoid wound complications...

Complications from diabetic foot ulcers often lead to increased patient morbidity. Much debate still ensues concerning surgical versus conservative management of neuropathic diabetic foot ulcerations. The present study assessed and compared the efficacy of metatarsal head resection and medical approach in the treatment of neuropathic diabetic foot ulcers located at the plantar surface of metatarsal heads. In a retrospective cohort study, 24 consecutive neuropathic diabetic foot ulcers in the lower area of the metatarsal heads that had undergone metatarsal head resection were included as the operative group...

Soft tissue defects around the foot and ankle region often present an awkward problem for plastic surgeons. The medial plantar artery flap raised from the non-weightbearing instep of the plantar foot offers a thick, sensorial, durable, and glabrous skin. The reversed sural artery flap offers a reliable option for coverage with the advantages of a wide arc of rotation, adequate dimensions, and a reliable blood supply. The present study compared the outcomes of the medial plantar artery flap and the distally based sural artery flap in foot and ankle reconstruction...
