Diabetic Foot

The diabetic foot is one of the complications due to diabetes.
Diabetes is a chronic metabolic disorder associated with elevated glucose values in the blood, a condition known as hyperglycemia. There are several types: Type 1 diabetes is characterized by a lack of production of insulin from the pancreas, Type 2 diabetes is caused by a lack of insulin response from its target cells (insulin resistance).
In time, diabetes, leads to numerous and serious complications, including the most frequently can manifest a condition known as “diabetic foot”.
The diabetic foot is the result of complications borne by the blood circulation and the peripheral nervous system. The narrowing of the arteries (vasoconstriction) leads to a decrease in the blood supply to the extremities (peripheral arterial disease).
Peripheral arterial disease has as a consequence the lower supply of oxygen and nutrients to the foot; bones and joints tend to weaken, the foot becomes flat and you create new pressure points where the skin may be damaged, these lesions can evolve to true ulceration.
The damage in the peripheral nervous system leading to reduced sensitivity to pain (diabetic neuropathy) are more likely to be injured or difficulty in recognizing situations of suffering (for example not suitable footwear).

Prevention

Prevention is the best weapon available to the diabetic patient to avoid foot ulcers. It is very important, in the presence of sensory neuropathy, check the status of the foot frequently as in the absence of painful stimuli could, for example, continue to wear an inappropriate shoe that could compromise the health of the foot.

    Central venous stenosis is one of the most challenging complications in hemodialysis patients. Venous thoracic outlet syndrome is an underappreciated cause of central venous stenosis in a dialysis patient that may result in failed percutaneous intervention and loss of a functioning dialysis access. The surgical management of venous thoracic outlet syndrome is confounded by the […]
