Complications The patient has a deep<unk>  at the knee, and radiography is used to ensure there are no hidden bone fractures. Bacterial infection of<unk>  can impede the healing process and lead to life-threatening complications. Scientists at Sheffield University have used light to rapidly detect the presence of bacteria, by developing a portable kit in<unk> hich specially designed molecules emit a light signal<unk> hen<unk>  to bacteria. Current laboratory-based detection of bacteria can take hours or days.<unk> orkup<unk> s that are not healing should be investigated to find the causes; many microbiological agents may be responsible. The basic<unk> orkup includes evaluating the<unk> , its extent and severity. Cultures are usually obtained both from the<unk>  site and blood. X-rays are obtained and a tetanus shot may be administered if there is any doubt about prior vaccination. Chronic Non-healing<unk> s of the diabetic foot are considered one of the most significant complications of diabetes, representing a major<unk> orldwide medical, social, and economic burden that greatly affects patient quality of life. Almost 24 million Americans—one in every twelve—are diabetic and the disease is causing<unk> idespread disability and death at an epidemic pace, according to the Centers for Disease Control and Prevention. Of those<unk> ith diabetes, 6.5 million are estimated to suffer<unk> ith chronic or non-healing<unk> s. Associated<unk> ith inadequate circulation, poorly functioning veins, and immobility, non-healing<unk> s occur most frequently in the elderly and in people<unk> ith diabetes—populations that are sharply rising as the nation ages and chronic diseases increase. Although diabetes can ravage the body in many<unk> ays, non-healing ulcers on the feet and lower legs are common outward manifestations of the disease. Also, diabetics often suffer from nerve damage in their feet and legs, allowing small<unk> s or irritations to develop<unk> ithout awareness. Given the abnormalities of the microvasculature and other side effects of diabetes, these<unk> s take a long time to heal and require a specialized treatment approach for proper healing. As many as 25% of diabetic patients<unk> ill eventually develop foot ulcers, and recurrence<unk> ithin five years is 70%. If not aggressively treated, these<unk> s can lead to amputations. It is estimated that every 30 seconds a lower limb is amputated somewhere in the<unk> orld because of a diabetic<unk> . Amputation often triggers a downward spiral of declining quality of life, frequently leading to disability and death. In fact, only about one third of diabetic amputees<unk> ill live more than five years, a survival rate equivalent to that of many cancers. Many of these lower extremity amputations can be prevented through an interdisciplinary approach to treatment involving a variety of advanced therapies and techniques, such as debridement, hyperbaric oxygen treatment therapy, dressing selection, special shoes, and patient education.<unk> hen<unk> s persist, a specialized approach is required for healing.
