[Mononuclear magnesium in elderly hypertensive patients treated with thiazide].

PURPOSE: To study mononuclear magnesium and serum cations (Na, K and Mg) in elderly hypertensive patients treated with hydrochlorothiazide during 90 days. PATIENTS AND METHODS: 15 elderly hypertensive patients treated with hydrochlorothiazide, 25 mg/day or placebo. A method of freezing produced total lysis of the cells; Mg was measured by atomic spectrophotometry. RESULTS: No differences were noted in mononuclear or serum magnesium in the thiazide or placebo treated patients, and the diuretic produced significant decreases in supine systolic and diastolic blood pressure. CONCLUSION: Magnesium supplementation does not seem essential in most patients in this conditions.

[Lymphocytic and serum magnesium in older healthy and hypertensive subjects].

PURPOSE: To study the lymphocyte and serum magnesium in older patients with and without arterial hypertension. PATIENTS AND METHODS: We studied the lymphocyte and serum Mg in 22 older patients, with diastolic blood pressure between 95 and 120 mmHg, not receiving drug treatment. A method of freezing produced total lysis of the cells. RESULTS: The mean lymphocyte Mg concentration in the older patients was 1.15 +/- 0.74 picomoles per 100 cells, significantly higher (p less than 0.05) than in the control group, that was 0.77 +/- 0.32 picomoles per 100 cells (lymphocyte Mg in older hypertensive patients/control = 1.49); there were no significant differences between groups with regard to serum Mg. Twelve older normotensive men studied also had lymphocyte Mg significantly higher than in the respective control group (lymphocyte Mg in older normotensive men/control = 1.70) and the serum Mg was also significantly higher than in the control group (1.63 +/- 0.12 versus 1.44 +/- 0.22 mEq/l. CONCLUSION: Since the high intracellular Mg concentration in the elderly patients may more accurately reflect the total body Mg status. We suggest to use Mg and Mg sparing diuretics in these patients, both hypertensive and normotensive, cautiously.

[Electrocardiographic changes in pancreatitis].

Of 400 patients with acute, chronic or chronic relapsing pancreatitis surveyed in the present study, only 54 had had ECG in their files. Among these, 80% showed ECG alterations, mostly sinus tachycardia and diffuse disturbances of ventricular repolarization. The causes of these alterations are, as yet controversial. Some explanations for these alterations are hypovolemia, sepsis and acute inflammatory state. Other important findings in the patients were bundle branch block, not encountered either before the pancreatic crisis or after its resolution, nor was dielectric effect and lesion current observed in either the acute and chronic forms. The possibility of the presence of previous cardiopathy in patients with high alcoholic intake, Chagas' disease, high blood pressure or diabetes, which are quite likely in these patients, should be recalled as important factors: marked electrolytes disorders were not frequent and did not correlate with ECG findings. The aim of this study is to highlight the importance of ECG during systematic search in the follow-up of patients with pancreatitis, in order to better understand associated cardiac disorders and to improve diagnosis, prevention and treatment.
