Elderly diabetic patients are particularly burdened by foot disease. The main causes for foot disease are peripheral neuropathy, foot deformities and peripheral arterial disease (PAD). Other risk factors include poor vision, gait abnormalities, reduced mobility an medical co-morbidities. The risk of major amputations increases with age, along with the increased prevalence of these risk factors. Th true risk of amputation and other burdens of foot disease in the elderly are likely underestimated by current epidemiological data. Th prevalence of neuropathy, foot deformities and PAD as well as the risk of amputation all increase with age even in non-diabetic patients. The principles of prevention and management of diabetic foot disease may also apply to large segments of the elderly non-diabetic population. Foot ulcer prevention relies on the identification of high risk patients and avoidance of triggering events, such as ill-fitting shoes, walking barefoot or poor self-care. PAD is a major cause of amputation and should be prevented by lifelong attention to glycaemic control, treatment of hypertension and dyslipidemia, and avoidance of smoking. The treatment of foot ulcers relies on pressure relief (off-loading), wound debridement, and treatment of infection and ischemia. It requires an individualized approach considering the patient's co-morbidities and functional status. Off-loading remains essential, but devices such as total contact casts or crutches can only rarely be implemented. However, providing adapted standard foot-wear and insisting on its consistent use even at home is often effective. The benefits of aggressive vascular or orthopaedic surgery should be weighed against the risks of prolonged hospitalisation and resulting functional decline. Greater attention to prevention and individualized care are needed to reduce the burden of diabetic foot disease in the elderly.

The aim of our study was to analyse the foot infections in diabetic patients. We analysed foot ulcerations in 124 diabetics who attended outpatient foot clinic, or were hospitalized in the period from 1996 to 2006. Basic neuropathy screening examination was made with cotton wisp, pin-prick, tuning fork, and monofilament. For evaluation of leg ischemia, besides the evaluation of the presence of pedal pulses, the ankle-brachial pressure index was measured. If the infection of foot ulceration was clinically present, bacteriology examinations was performed. In the case of deep wound infection, x-ray examination was made. If bone destruction was present, osteomyelitis was diagnosed by technecium bone scanning and by technecium-labelled leukocyte scan. Deformation and destruction of the bone without infection was appoited as Charcot neuroarthropathy. Foot ulcer infection was found in 58 % diabetic patients, wounds were more often deep (80 %). Infection was not associated with special location of foot ulcer. Two-third of the total infected wounds were associated with leg ischemia and 30.6 % of infected ulcer ended with leg amputation. More foot ulcer infections were found in the diabetics with HbAlc over 8 %. Infection was coupled with diabetic retinopathy (in 63 % patients) (p=0.023), and also with diabetic nephropathy (in 66 % patients) (p=0.012). Bacteriology examination revealed most often Staphylococci (45.8 %), antibiotic therapy was made most often with chinolones. Osteomyelitis was present in 34.7 % of foot ulcer infections. In 14 diabetics (56 %) after antibiotic therapy it was not necessary to perform a leg amputation. HbAlc seems to be a significant predictor of osteomyelitis (p<0.02; OR=1.76). In conclusion, we confirmed that diabetic foot infections, especially on ischemic leg, in diabetics with poor metabolic control and chronic diabetic microvascular complications, are associated with a higher risk of leg amputations. Further, it is possible to cure osteomyelitis successfully without surgery in more than half the cases (Tab. 1, Ref. 24). Full Text in free PDF www.bmj.sk.
