Hyperbaric Oxygen Therapy and Angiogenesis in Diabetic Patients With Foot Ulcers
Diabetic foot ulcers are a major cause of morbidity and mortality, accounting for approximately two-thirds of all non-traumatic amputations performed in the United States. The cost of foot ulcers in diabetic patients averages almost $28,000 for the two years after diagnosis of the ulcer. Hyperbaric oxygen (HBO) serves as primary or adjunctive therapy for a diverse range of medical conditions. HBO also has been used as an adjunct to antibiotics, debridement, and revascularization in the therapy of chronic, nonhealing wounds associated with diabetes or non-diabetic vascular insufficiency.
The aim of the study is to assess whether hyperoxia induced angiogenesis in diabetic patients with foot ulcers.

Medical and Biotech [MESH] Definitions
Common foot problems in persons with DIABETES MELLITUS, caused by any combination of factors such as DIABETIC NEUROPATHIES; PERIPHERAL VASCULAR DISEASES; and INFECTION. With the loss of sensation and poor circulation, injuries and infections often lead to severe foot ulceration, GANGRENE and AMPUTATION.
Peripheral, autonomic, and cranial nerve disorders that are associated with DIABETES MELLITUS. These conditions usually result from diabetic microvascular injury involving small blood vessels that supply nerves (VASA NERVORUM). Relatively common conditions which may be associated with diabetic neuropathy include third nerve palsy (see OCULOMOTOR NERVE DISEASES); MONONEUROPATHY; mononeuropathy multiplex; diabetic amyotrophy; a painful POLYNEUROPATHY; autonomic neuropathy; and thoracoabdominal neuropathy. (From Adams et al., Principles of Neurology, 6th ed, p1325)
Foot Deformities, Acquired
Distortion or disfigurement of the foot, or a part of the foot, acquired through disease or injury after birth.
Tarsal Tunnel Syndrome
Entrapment of the distal branches of the posterior TIBIAL NERVE (which divides into the medial plantar, lateral plantar, and calcanial nerves) in the tarsal tunnel, which lies posterior to the internal malleolus and beneath the retinaculum of the flexor muscles of the foot. Symptoms include ankle pain radiating into the foot which tends to be aggravated by walking. Examination may reveal Tinel's sign (radiating pain following nerve percussion) over the tibial nerve at the ankle, weakness and atrophy of the small foot muscles, or loss of sensation in the foot.
