When you have diabetes, you are especially prone to foot infections, yeast infections, urinary tract infections, and surgical site infections. 2 High blood sugar levels contribute to this process. As a result, the risk of infection is increased if your diabetes is poorly controlled.
What causes antibiotic resistance?
The main cause of antibiotic resistance is antibiotic use. When we use antibiotics, some bacteria die but resistant bacteria can survive and even multiply. The overuse of antibiotics makes resistant bacteria more common. The more we use antibiotics, the more chances bacteria have to become resistant to them.

How to care for diabetic feet?
FOOT CARE IS CRITICAL IF YOU HAVE DIABETES 1 Never walk barefoot, even around the house. 2 Don’t wear sandals —the straps can irritate the side of the foot. 3 Wear thick socks with soft leather shoes. Leather is a good choice because it “breathes,” molds to the feet and does not retain moisture. Laced-up shoes with cushioned soles provide the most support. In addition, pharmacies carry special “diabetic socks” that protect and cushion your feet without cutting off circulation at the ankle. These socks usually have no seams that could chafe. They also wick moisture away from feet, which reduces risk for infection and foot ulcers. 4 See a podiatrist. This physician can advise you on the proper care of common foot problems, such as blisters, corns and ingrown toenails. A podiatrist can also help you find appropriate footwear—even if you have foot deformities. Ask your primary care physician or endocrinologist for a recommendation, or consult the American Podiatric Medical Association, www.apma.org.

What is the current concept of diabetic foot infection?
Diabetic foot infections: current concept review The purpose of this manuscript is to provide a current concept review on the diagnosis and management of diabetic foot infections which are among the most serious and frequent complications encountered in patients with diabetes mellitus. A literature review on diabetic foot infections with emphasis on pathophysiology, identifiable risk factors, evaluation including physical examination, laboratory values, treatment strategies and assessing the severity of infection has been performed in detail. Diabetic foot infections are associated with high morbidity and risk factors for failure of treatment and classification systems are also described. Most diabetic foot infections begin with a wound and once an infection occurs, the risk of hospitalization and amputation increases dramatically. Early identification of infection and prompt treatment may optimize the patient's outcome and provide limb salvage.

How does DFI management help diabetics?
Hospital Medicine Guidelines for Management of Diabetic Foot Infections Studies have demonstrated that DFI management according to guidelines improves survival, reduces complications, and is cost-effective with a major clinical outcome of reduced amputations. In the U.S. alone, there are an estimated 25.8 million people with diabetes, or about 8.3% of the population. Due to comorbidities of peripheral neuropathy and peripheral vascular disease associated with diabetes, these patients are at higher risk for developing foot infections. Among the myriad diabetes complications, diabetic foot infections (DFI) are the main reason for diabetes-related hospitalizations and lower-extremity amputations. U.S. hospitals admit roughly 5,700 patients per year for DFI; 71,000 lower-extremity amputations are attributed to diabetes.1,2 Studies have demonstrated that DFI management according to guidelines improves survival, reduces complications, and is cost-effective with a major clinical outcome of reduced amputations.3 But prospective observational studies have shown that, in practice, guidelines often are not followed and can lead to poor outcomes.4 Studies suggest a need for more simple, straightforward guidelines. In June 2012, the Infectious Diseases Society of America (IDSA) updated its 2004 guidelines on the management of diabetic foot infections.5 Although IDSA made no major changes to its recommendations, the 2012 guidelines were revised to be more simple and clear. These new guidelines have been reviewed and endorsed by SHM. All patients with suspected DFI should be assessed on three levels: the patient, the extremity involved, and the wound. Patients should be assessed for signs of systemic illness or metabolic derangements. The extremity should be examined for peripheral a Continue reading >>
