A study was designed to evaluate the normal value of 24 hr urinary calcium levels in the city of Yazd. The average urinary excretion of calcium in a sample of 329 persons randomly selected was 232 mg/day, while patients with a history of recurrent urolithiasis excreted 20X mg/day. There is evidence which shows that more important factors than the amount of urinary calcium exist which influe...

BACKGROUND Recently long-term safety of bisphosphonate raises issues about the duration of therapy. We examined the effects of a drug holiday (DH) on bone mineral density (BMD) and bone turnover markers. METHODS In Korean, 125 women of 50 years of age or older with T-score≤-3.0 of their lumbar or left femoral BMD initiated bisphosphonate from 1999 based on retrospective chart review. 125 pati...

Objectives: To assess the efficacy of calcium /creatinine ratio (CCR)as a diagnostic test for the prediction of preeclampsia, and also to determine the changes in urinary excretion of calcium in preeclampsia and normotensive women. Material &Methods: Urinary calcium creatinine ratio was determined in a spot urine sample in 145 asymptomatic pregnant women between 20-28 weeks of gestation, who at...

  intravenous glucocorucoid pulse therapy is a common treatment for immunologically origin diseases but it can not be considered a completely bening treatment.the effects of long term administration of glucocorticoids on calcium and phosphorus metabolism are week known ,but is less in known about the effect of pluse therapy.the purpose of this study was to investigate the effect of methylpredn...

abstract   background: hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. the presence of hydronephrosis is not synonymous with o...

INTRODUCTION The urinary protein/creatinine ratio has been used instead of 24-hour proteinuria in Nephrology practice for the follow-up of glomerular diseases, considering the advantages of collection and the low cost. However, there are still doubts as to its applicability both for an isolated evaluation and for the follow-up of patients with lupus nephritis. OBJECTIVE To evaluate 24-hour pr...

OBJECTIVE To report a case of an infant with endstage renal failure caused by primary hyperoxaluria. METHODS The review of the literature showed the rarity of the disease. In France, the prevalence is about 1.05/million and the incidence rate is 0.12/million/year. A survey, performed in international specialized centers in 1999, documented 78 cases in infants; in 14% of them the initial onset...

Serum creatinine, urinary creatinine and endogenous creatinine clearance were measured in various age groups in normal subjects and in those suffering from renal disorders. Serum creatinine was found to be significantly high in cases of chronic renal failure and renal hypertension. Serum and urinary creatinine levels in normal subjects were found to vary with the age. (JPMA 31:225, 1981).
