Prevalence and symptoms of idiopathic hypercalciuria in primary school students in Sanandaj

Determination of prevalence rate of idiopathic hypercalciuria [IH] in primary school students in Sanandaj. This was a descriptive-analytic study and included 506 primary school students. First we measured the ratio of urine calcium to urine creatinine [UCa/UCr] as screening test then 24 hour urine calcium of the patients who had UCa/UCr ratio more than 0.2 mg/mg [31 patients] was measured. Those with 24 hours urine calcium of more than 4 mg/kg were regarded hypercalciuric, [3 boys and 12 girls]. Data were introduced into SPSS win soft ware, represented in the form of frequency distribution table and analyzed by means of Chi square and T-tests. 248 patients were female and 258 were male. 32 patients [6.32%], 11 boys and 21 girls had UCa/UCr ratio more than 0.2 mg/mg, but 15 patients [3 boys and 12 girls] had excretion of more than 4mg/kg/day calcium in urine which encompassed 3% of the students [1.2% boys, 4.8% girls]. The results of this study indicated the Incidence of hypercalciuria among student girls was more than that of boys. 95th percentile for urine Ca/Cr is 0.198 for boys and 0.253 for girls. Considering the effect of hypercalciuria on bone density and growth which has more importance in girls, it is recommended to evaluate such effect in a more comprehensive study

[ comparison of platelet count and volume in normal and preeclamptic pregnancy]

Background: hypertensive disorders in pregnancy are one of the high risk pregnancies. There are considerable evidences about the role of platelet in preeclampsia in pathophysiology. In this study the mean of volume platelet and count in normal pregnant women and preeclamptic women were compared

Materials and methods: in a case - control study 35 normal pregnant women who matched in age, gestational age, and gravity were compared with 35 preeclamptic women to determine the mean volume platelet and count from 2003 to 2005 on pregnant women who admitted at obstetric ward of Taleghani Hospital and outpatient department were entered the study

Results: totaly 70 pregnant women [35 case of preeclamptic women and 35 control groups] , were evaluated. Mean age in normal pregnant women were 27+/- 5.4 years and in preeclamptic group was 27.2 +/- 5.3 years [range:17-38 years]. The Number of gravity of the patients Were between 1 to 8.the mean of gestational age in both group were 32.7 +/- 5.1 weeks[range:20-41 weeks]. In normal group no one has platelet count less than 150.000/[micro]l and in none of them means platelet volume was more than 10fm. In preeclamptic group in 16[45.7%] cases platelet count was less than 150000/[micro]l and in 9 [25.7%] mean platelet volume of >/= 10fl was obtained. In normal pregnant women mean platelet count was 208300/[micro]l+/- 4600 and mean of mean platelet volume was 8.2+/-0.63fl. In preeclamptic women mean platelet count was 154000/[micro]l+/-84000 [P<0.005] and mean of mean platelet volume was 9.2 +/- 0.84 fl. [P<0.0001]

Conclusion: decrease in count and increase in size of platelets probably precede preeclampsia
