1. The possible roles of the diet and of intestinal absorption in the increased excretion of oxalate by patients with renal calcium stones have been studied. 2. Dietary surveys showed that the mean daily intake of oxalic acid by stone-formers was not significantly different from that of non-stone-formers. 3. The mean urinary excretion of oxalate, expressed as an oxalate/creatinine molar ratio, ...

Eighty-eight normotensive gravid women between 24 and 34 weeks of gestation underwent urine evaluation for the presence of microalbuminuria and urinary calcium excretion (calcium/creatinine ratio). Preeclampsia subsequently developed in 83% of patients with a high level of microalbuminuria (greater than or equal to 11 micrograms/ml) and a low calcium/creatinine ratio (less than or equal to 0.04...

in spite of vast improvements in urinary stone treatment (eswl, pnl, ureteroscopy, etc.), metabolic workup concerning the existence of stone forming risk factors are of great importance and can lead to control and even prevention of urinary stone formation in these patients. in this analytical case-control study performed on 266 persons [110 normal persons (56 males and 54 females), 76 patients...

Objective: Due to worldwide variations, reference values of urinary calcium to creatinine ratio in pediatric population are not yet well established. To determine normal values for urinary calcium to creatinine ratio and its relation to urinary sodium or potassium, a descriptive (correlation type) study was conducted in 7 to 12 years old healthy children in Urmia, Iran. Methods: Primary school ...

background:the first step in diagnosis of diabetic nephropathy is measurement ofalbumin in a spot urine sample. the aim of this study was assessment of the accuracy of urinary albumin to creatinine ratio (uacr) in random urine specimens (rus) for microalbuminuria and macroalbuminuria screening in iranian diabetic patients. methods:a total of 200 diabetic patients participated to our study. 24 h...

Aim: The role of vitamin D has been studied in growth and reproduction, carcinomas, psoriasis etc. Even in preeclampsia aberration in calcium homeostasis was found to be associated with decreased calcitriol levels. In present study, we investigated the role of vitamin D supplementation in regulation of calcium homeostasis and prevention of preeclampsia. Methods: The study comprised of 200 primi...

In spite of vast improvements in urinary stone treatment (ESWL, PNL, ureteroscopy, etc.), metabolic workup concerning the existence of stone forming risk factors are of great importance and can lead to control and even prevention of urinary stone formation in these patients. In this analytical case-control study performed on 266 persons [110 normal persons (56 males and 54 females), 76 pat...

abstract introduction : conjugated linoleic acid (cla) has been shown to positively influence on calcium and bone metabolism in experimental animals and cell culture, but there are limited human data available. material and methods : this double-blind, placebo-controlled trial study was done on 76 healthy post-menopausal women (aged 55.1) which randomly assigned to receive daily four cla capsul...

background urinary tract infection (uti) is common in children. uti with or without vesico-ureteral reflux (vur) may result in renal scarring. severe renal scarring impairs renal function and may result in hypertension, renal insufficiency, and end stage renal disease requiring dialyses or transplantation. beta 2 micro-globulin (ß2mg) is a low molecular weight protein freely filtered by the glo...
