RESUMO
Ninety-five subjects aged 60 years and over underwent casual and ambulatory blood pressure (BP) measurements as well as weight, height, both waist and hip circumferences and both upper arm and thigh circumferences. Most anthropometric variables were significantly correlated with measures of BP. One stepwise regression analysis was applied to reveal that among measures of BP, 24-hour systolic BP had the strongest correlation with waist/hip ratio and awaking diastolic BP the strongest correlation with weight, both waist and hip circumferences and body mass index. Another was used to show that waist/hip ratio was the best overall predictor of systolic BP and weight the best overall predictor of diastolic BP. We suggest that (1) ambulatory BP be superior to casual BP in evaluating effect of weight and body fat's distribution on BP and (2) waist/hip ratio more important than weight in the hypertensive target organ damage and the prognosis of hypertension in Chinese elderly population.

Does ambulatory blood pressure correlate with the renal function damage better than clinic blood pressure in isolated systolic hypertension, as has been reported in other target organ involvement in combined systolic/diastolic hypertension? We investigated the correlation of serum beta-2 microglobulin concentration and both 24-h urine beta-2 microglobulin concentration and excretion as measures (suggestive) of glomerular filtration rate and tubular reabsorption, respectively with both ambulatory and clinic blood pressure in 19 health normotensive (68 +/- 4.9 years) and 50 isolated systolic hypertensive elderly individuals (69 +/- 5.4 years). Serum beta-2 microglobulin concentration and 24-h urine beta-2 microglobulin concentration and excretion were higher in the isolated systolic hypertension than in the normotensive group (P < 0.05). In isolated systolic hypertensive patients, 24-h urine beta-2 microglobulin concentration and excretion were related to ambulatory blood pressure (r = 0.32-0.40, P < 0.05), but not to clinic blood pressure; waking systolic blood pressure had the strongest correlation with both 24-h urine beta-2 microglobulin concentration and excretion among derivatives of ambulatory blood pressure (r = 0.35 and 0.40, P < 0.05). We conclude that ambulatory blood pressure, especially waking systolic blood pressure, is superior to clinical blood pressure in predicting renal function impairment, in isolated systolic hypertensive patients.

A case of a relatively uncommon disease, jejunal, diverticulosis, is reported. The case presented an unusual complication, massive melena. The patient was successfully treated and cured by resection of the involved portion of jejunum. In the management of gastrointestinal hemorrhage in the elderly one must always have in mind this infrequent pathological entity, especially when the small bowel is suspected as the site of bleeding.
