RESUMEN
Twenty-two patients with stable cardiac disease drove into a radar trap while having an ambulatory electrocardiogram. All patients reported cardiac symptoms, heart rate increases, and appearance of repetitive ventricular arrhythmias. Myocardial ischemia was observed in some patients. Being caught while car speeding under the stresses of daily life may induce potentially dangerous cardiac effects. The data confirm the effects of stress and adrenergic tone on ventricular arrhythmias.

The instruction of the patient with diabetes mellitus, aimed at the mastery of technical elements in self-management, as well as his/her education to a coherent behavior respecting both the quality of metabolic control and the quality of life, are basic elements of diabetes treatment. To neglect them would be a professional error. The physician in charge of a diabetic patient must take into account the knowledge and the capabilities that have been acquired by the patient before, as well as his/her actual demand for information and instruction. Concepts and methods of learning and teaching for diabetic patients that have been developed and applied over the last decade may serve as reference for all levels of health education.

Sixty patients were treated for 1 year for essential uncomplicated hypertension, 30 with beta-blockers alone (BB) and 30 with BB and chlorthalidone (CTD). BB did not affect serum K+ or Mg++. In the BB-group there was a statistically significant trend towards retention of Mg++ in a loading test, but the effect was clinically marginal. BB + CTD reduced serum K+ and Mg++ and caused significant Mg++ depletion, as shown by the Mg++ loading test. All the effects were highly significant and were clinically important. The metabolic perturbations due to CTD are potentially dangerous and make this drug unattractive as 'first choice' treatment for hypertension.

Indirect calorimetric studies were performed during a 100 g oral glucose tolerance test in diabetic patients with varying degrees of endocrine pancreatic dysfunction and in a control group of normal subjects. In 3 obese diabetics the study was repeated after a 3 day protein sparing modiefied fast. In diabetic patients the results show alterations of oxidation and storage of carbohydrates, related to insulin secretion deficiency on the one hand, and to overweight on the other. Endocrine pancreatic insufficiency may account directly for alterations observed in individuals with decreased or absent insulin response to glucose load, wheras metabolic factors such as adipose mass, hepatic steatosis, and peripheral insulin resistance appear to be responsible for alterations in carbohydrate oxidation and storage in subjects with relative endocrine pancreatic insufficiency, particularly obese diabetics.
