Alcoholic ketoacidosis: a case report

A 43-year-old alcoholic presented in coma with ketoacidosis, after three days of nausea and feeling generally unwell, which had been preceded by a prolonged three-week period of heavy alcohol consumption with poor dietary intake. The acidosis responded rapidly to intravenous dextrose. This is the first Scottish report of a case of alcoholic ketoacidosis.     

Early cardiovascular changes with ibopamine: evidence for a biphasic haemodynamic action.

1. The haemodynamic effects of ibopamine, an oral dopamine derivative, were studied in eight patients with left ventricular dysfunction using invasive catheterisation techniques. 2. An early rise was seen in the mean right atrial pressure (P less than 0.05), the mean capillary wedge pressure (P less than 0.01) and the mean pulmonary arterial pressure (P less than 0.001) which occurred at 15 min and persisted for 30 min. 3. A second, later, positive chronotropic effect was seen as an increase in the heart rate (P less than 0.05) at 45 min with an increased cardiac output (P less than 0.05) persisting above baseline values at 1 h, but with no change in stroke volume. 4. These results support a biphasic mode of action for ibopamine which may be explained by a time phase difference in alpha- and beta-adrenoceptor stimulatory effects.     

抗人热休克蛋白60效价增高提示急性心源性胸痛患者的一年预后不良

目的：探讨抗人热休克蛋白60或抗分枝杆菌热休克蛋白65抗体是否能够预测因急性心源性胸痛入院的患者一年预后不良。设计：前瞻性观察研究。地点：教学医院。患者：连续588例急诊收治的疑似急性心源性胸痛患者。主要观察指标：测定入院后晨起血样的抗人热休克蛋白60和抗分枝杆菌热休克蛋白65效价。出院后终点为冠心病死亡、非致死性心肌梗死、冠状动脉搭桥术、经皮穿刺腔内冠状动脉成形术、血管造影或因心脏缺血性胸痛加重再次入院。
