METHODS: We retrieved blood glucose measures from the emergency department database and selected a subgroup of individuals having both the radiological marker Evans\' index (EI) values and blood glucose measures.
RESULTS: Out of 1221 consecutive patients submitted to axial Computed Tomography scans, a blood glucose measure was detected in 841 individuals. 176 scans (21 %) showed an EI > 0.30. According to the blood glucose categorization, diabetic patients were 104 (12 %), 25 of them (24 %) were dilated (mean EI 0.33). The age difference between dilated and not-dilated ventricles is about ten years in not-diabetic participants, whereas it is five years in diabetic participants. The age difference between dilated and not-dilated ventricles is about 10 years in diabetic men, whereas it zero in diabetic women.
CONCLUSIONS: Pathological ventricular enlargement is more frequent in men and in the elderly. In diabetic patients (especially women), the cerebral ventricles enlarge faster than in non-diabetic individuals. Age, sex, and diabetes may interact in determining how cerebral ventricle size changes over time, especially in diabetic women, making routine brain imaging advisable in these patients after the age of 70 years.
方法:我们从急诊科数据库中检索了血糖测量值,并选择了具有放射标记Evans指数(EI)值和血糖测量值的个体亚组。
结果:在连续1221例接受轴向计算机断层扫描的患者中,在841例患者中检测到血糖指标.176次扫描(21%)显示EI>0.30。根据血糖分类,糖尿病患者为104(12%),其中25例(24%)扩张(平均EI0.33)。在非糖尿病参与者中,扩张和未扩张的心室之间的年龄差异约为十年,而糖尿病参与者为5年。在糖尿病男性中,扩张和未扩张的心室之间的年龄差异约为10岁,而糖尿病女性为零。
结论:病理性心室扩大在男性和老年人中更常见。糖尿病患者(尤其是女性),脑室扩张速度比非糖尿病患者快。年龄,性别,和糖尿病可能在确定脑室大小随时间变化的过程中相互作用,尤其是糖尿病女性,在这些70岁后的患者中,建议进行常规脑成像。
