Signs of foot ulcer include sudden appearance or onset of pain in a foot or ankle with at least one of the following: erythema, edema, or discharge of pus. Chronic foot ulcers can be symptomatic if erythema, edema or discharge are present. The presence of foot ulcers is a key factor at presentation in patients with diabetes.
This is one area of a chronically high rate of chronic foot problems. A foot ulceration may disappear on admission to the hospital with no further intervention in a period of several weeks. This is a high incidence of nonhealing chronic foot ulceration which affects millions of people globally.
Nearly half of the ulcer cases were of unknown cause. The foot has many natural hazards such as overuse of footwear, prolonged inactivity or disability, and chronic venous insufficiency which can all lead to ulcer formation. Other factors associated with poor ulcer recurrence rates are age, size of ulcer, duration of ulcer, presence of a granulation tissue, and underlying diabetes. A low recurrence rate depends not only upon foot care but also good wound healing. It can be difficult to accurately diagnose the cause of ulcer due to the long delay between first symptoms to treatment initiation. There may be significant benefit from research into ulcer-specific treatments which may lead to decreased recurrence rates and decreased amputation rates.
It has been reported that up to 30% of the population has at least one foot ulcer. On the basis of the latest data, which was compiled by the National Health Survey and funded by the Agency for Healthcare Research and Quality, as of 2013 there were more than 50 million people in the United States who had at most five or more foot ulcers annually.\n
foot ulcers are sometimes surgically debrided and a skin graft applied. Wounds with open edges often require skin flaps. Hyperbaric oxygen may help speed healing.
Foot ulcers are a common, chronic, debilitating, and often neglected condition that, if left untreated, can cause death. The foot is a muscular structure, and, as with most muscular structures, has an inherent tendency towards injury. As the toe is the most prominent area in relation to the ground, it becomes the first point of contact when turning, walking or running. Accordingly, foot ulcers have the potential to cause serious and even amputating pathology. Foot ulcers are therefore obviously significant conditions in relation to health and wellbeing. The pathogenesis and treatment of this condition are complex, but a great number of strategies have been described. The diagnosis of a foot ulcer is a complex process and requires a thorough investigation.
The prevalence of acute neuropathy with mononeuropathy and polyneuropathy in foot ulcer patients did not show significant differences between groups. Although one could find age as one of the most important factors affecting the development of acute foot ulcers, this should not be considered the case for any other clinical features and clinical picture of these subjects.
There is no significant difference in QOL between those treated with Chlorhexidine HOB daily solution and those who were treated with Chlorhexidine gel daily solution; however the participants that experienced ulcer healing, pain reduction, or the presence of calluses had a marked improvement in their QOL. There was no significant difference between those who received either topical product and those who were on treatment for the systemic effects of CHX (mainly GI disturbances). We conclude that chlorhexidine does not improve the QOL for those with foot ulcerations.
More research is needed to develop successful therapies for ulcers. In the meantime, treatment focuses on stopping the bleeding and preventing foot deformities. When that isn't enough, doctors sometimes employ other treatments such as the use of electric impulses or high-frequency ultrasound to help heal the lining of the foot. For patients who have experienced foot ulcerations, a referral to a foot specialist is recommended. If foot pain is severe, a referral should be made if there is no improvement in 10 to 14 days. Patients should wear supportive socks while walking and staying off of any abrasives like glass, porcelain, or plastic when possible.
Despite the limited amount of research conducted, there seems to be much room for growth in the area of oral care in the prevention and treatment of foot ulcers. Chlorhexidine alone appears to be an effective and inexpensive adjunct to healing ulcers. The use of a 0.12% chlorhexidine mouthwash for three days after amputation significantly reduced the healing time and the rate of dehiscence of amputation ulcers.
We can show that using chlorhexidine on the plantar surface of the foot can reduce bacterial counts but can no longer be effective in preventing plantar ulceration and may even increase ulcer development.
The present findings clearly indicate foot ulceration as an autosomal dominant genetic trait among people with a high familial risk of the condition. There are two plausible explanations for the present data: first, patients with foot ulcers do have a larger number of ulcerated peripheral somatosensory nerves as compared to people without foot ulceration. This may be due to an increased number of somatosensory A-delta fibres or to a lesser degree of mechanosensory C and A fibre-driven hypersensitivity induced by a reduced number of C-alpha-tryptase fibres. In this scenario, a defect in the maintenance of the nerves is assumed.
