Limb salvage in Charcot foot and ankle osteomyelitis: combined use single stage/double stage of arthrodesis and external fixation.

BACKGROUND: Charcot neuroarthropathy of the foot/ankle is a devastating complication of diabetes. Along with neuroarthropathy, osteomyelitis can occur which can result in amputation. This prospective study evaluated a limb salvage procedure as an alternative to amputation through surgical treatment of osteomyelitis of the midfoot or the ankle and stabilization with external fixation. MATERIALS AND METHODS: Forty-five patients with Charcot arthropathy and osteomyelitis underwent debridement and attempted fusion with an external fixator. Chart and radiograph review was performed to assess the success of the fusion and eradication of infection. RESULTS: Out of 45 patients, 39 patients healed using emergent surgery to drain an acute manifestation of the infection while maintaining the fixation for an average of 25.7 weeks. Two patients were treated with intramedullary nail in a subsequent surgical procedure. In four patients, the infection could not be controlled, therefore a major amputation was carried out. CONCLUSION: For select patients, external fixation proved to be a reasonable alternative to below-knee amputation.

Low cholesterol levels are associated with short-term mortality in older patients with ischemic stroke.

BACKGROUND: The possible relationship between serum total cholesterol (TC) levels and outcome following ischemic stroke is still controversial. We evaluated the association between TC levels and 30-day mortality in a sample of older patients with acute ischemic stroke. METHODS: We enrolled 490 older patients with severe ischemic stroke consecutively admitted to University Hospital's Internal Medicine or Geriatrics Department. Stroke type was classified according to the Oxfordshire Community Stroke Project. The data recorded included clinical features, medical history, electrocardiogram, and blood analyses. Patients were divided into three groups by TC levels: group I (TC<4.1 mmol/L), group II (TC 4.1-5.2 mmol/L), and group III (TC>5.2 mmol/L). RESULTS: The overall mortality was 27.7%. Mortality was higher in patients with low TC levels (47.4%) compared with those with normal and high TC levels (23.0% and 24.1%, respectively). The odds ratio (OR) for short-term death was 2.17 (95% confidence interval [CI] 1.22-3.85) in group I compared with group III, after adjustment for age and gender. This result did not change after adjustment for possible confounders (OR 2.87; 95% CI 1.23-6.68). A similar trend was observed after adjustment for the Oxfordshire classification, age, and gender (OR 1.67; 95% CI 0.83-3.33). CONCLUSIONS: Short-term mortality following ischemic stroke is higher in older participants with low TC levels, independent of a large number of factors. Low TC levels might be useful in identifying frail older participants at high risk of stroke short-term mortality.
