Ischemic stroke in patients with diabetic foot.

AIM: The diabetic foot syndrome is the most frequent cause of hospitalization of diabetic patients and one of the economically most demanding complications of diabetes. People with diabetes have been shown to have higher mortality than people without diabetes, but the cerebrovascular risk profile of these patients is not fully evaluated. The aim of our study was to evaluate the possible role of diabetic foot as a cerebrovascular risk marker in type 2 diabetic patients. METHODS: We enrolled 102 type 2 diabetes patients with diabetic foot and 123 diabetic patients without diabetic foot. RESULTS: Statistically significant differences were found in the distribution of the main cardiovascular risk factors with exception of hypertension. We observed a higher prevalence of previous cerebrovascular events (transient ischemic attack, ischemic stroke) and of incidence of new onset cerebrovascular events at a 5-year follow-up. Regarding clinical subtype of ischemic stroke classified according to Trial of ORG 10172 in Acute Stroke Treatment (TOAST) classification on a retrospective and prospective basis, we observed a higher prevalence of both the lacunar and large artery atherosclerosis subtype with a slight higher prevalence of lacunar subtype in patients with diabetic foot. CONCLUSION: Our results show a worse cerebrovascular risk profile in diabetic patients with diabetic foot than in diabetic subjects without foot ulceration with a higher prevalence of cardiovascular risk factors and of anamnestic cerebrovascular events and incidence of new cerebrovascular events at a 5-year follow-up.

A case control study between diabetic and non-diabetic subjects with ischemic stroke.

AIM: The clinical and prognostic profile of diabetic stroke patients is still an unclarified topic. The aim of the present study is to compare clinical features and risk factor profile in diabetics and in non-diabetics affected by acute ischemic stroke. METHODS: We have included 98 diabetics and 102 matched non-diabetic subjects affected by acute ischemic stroke and matched by age (+/-3 years) and gender. We determined the Scandinavian Stroke Scale (SSS) on admission and the Rankin disability scale on discharge and after a 6 months follow-up. Ischemic stroke has been classified according to the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. We anamnestically evaluated the presence of hypertension, hypercholesterolemia, any records of transient ischemic attack, and stroke. Using conditional logistic regression analysis, we calculated adjusted odds ratio (OR) and 95% confidence interval (CI). RESULTS: Diabetes was associated with lacunar ischemic stroke subtype (OR 3.89, 95% CI 2.23-6.8), with a record of hypertension (OR 2.53, 95% CI 1.48-4.32), and with a better SSS score at admission (OR 0.58, 95% CI 0.36-0.96). The association of diabetes with lacunar stroke remained significant also after adjustment for hypertension (adjusted OR 3.37, 95% CI 1.9-5.99) or for large artery atherosclerotic and cardioembolic stroke subtypes (adjusted OR 2.69, 95% CI 1.08-6.69). CONCLUSIONS: Our study shows some significant differences in acute ischemic stroke among diabetics in comparison with non-diabetics (higher frequency of hypertension, higher prevalence of lacunar stroke subtype, lower neurological deficit at admission in diabetics).

Successful salvage therapy of intravenous cyclophosphamide for refractory polymyositis in an elderly patient: case report.

Dermatomyositis and polymyositis may affect children and adults and are now widely recognized as major causes of disability which, thanks to the introduction of immunosuppressive drugs, is often treatable, at least to some extent. Few data exist regarding polymyositis in elderly patients. We describe a case of refractory life-threatening polymyositis in an elderly patient, successfully treated with intravenous cyclophosphamide.
