background: due to difficulty of obtaining a 24h urine (especially in children), a random urine calcium sample is recommended to detect of hypercalciuria. however, recent studies have shown that the urinary calcium/creatinine ratio varies with age and geographic areas. so, the aim of this study was determining the normal value of urinary calcium to creatinine ratio in healthy adolescent’s child...

background because of difficulty in obtaining a 24-hour urine collection in children, a random sample of urine is often used to calculate the urinary calcium to creatinine ratio. urinary calcium excretion might be influenced by genetic, geographic area, etc. in this study, the value of urinary calcium, creatinine, sodium and potassium excretion and age–related reference values for urine calcium...

1. In a prospective study involving fifty-six women, measurements of body weight, urinary creatinine, sodium and potassium and plasma sodium, potassium and renin activity were made in mid-pregnancy and at 36 weeks. The effect of sodium restriction and sodium ldading on these measurements was assessed in midpregnancy. 2. Mean plasma renin activity was significantly high'er throughout pregnancy t...

OBJECTIVE To test whether perioperative sodium bicarbonate infusion can attenuate postoperative increases in serum creatinine in cardiac surgical patients. DESIGN Double-blind, randomized controlled trial. SETTING Operating rooms and intensive care unit at a tertiary hospital. PATIENTS Cohort of 100 cardiac surgical patients at increased risk of postoperative acute renal dysfunction. IN...

Dogue de Bordeaux dog has been reported to be predisposed to a familial glomerulonephropathy that displays some morphological modifications reported in focal and segmental glomerulosclerosis. Prevalence of quantitatively abnormal renal proteinuria was recently reported to be 33% in this breed. The nature of the proteinuria was assessed by sodium dodecyl sulfate-agarose gel electrophoresis and d...

1. Blood pressure, height, weight and 24 h urinary output of sodium, potassium and creatinine were measured in over 500 adults of each sex during a health survey of the population of a small town. 2. Both systolic and diastolic pressure were significantly related to Quetelet's index (weight/height2) and heart rate. 3. There was no significant relationship between blood pressure and output of so...

Urine specimens were collected from 26 normal subjects, 10 patients with proven primary hyperparathyroidism, and eight patients with hypercalcaemia due to other causes. After overnight urine concentration, an oral water load was given to induce a diuresis and provide urine specimens with a relatively wide range of creatinine concentration for each subject. In normal subjects the urinary calcium...

BACKGROUND Many studies showed an association between dietary salt intake, blood pressure and increased CVD risk. The potential reason may be related to vascular structural and functional changes, through alterations in endothelial function. The central retinal arteriolar equivalent and urinary albumin reflected vascular endothelial dysfunction in different part of the body. The urinary sodium-...
