RESUMO
PURPOSE: Somatic growth is an important indicator of health in children. Adequate organ growth is essential in growth and directly related to body growth. We consider renal length as a surrogate of organ growth in growing children. Measurement of weight, height, and many anthropometric indices, such as body surface area (BSA), body mass index (BMI), and Rohrer and Kaup indices, are used to evaluate growth status. The aim of this study was to evaluate the association between renal length and somatic parameters and analyze the affecting factors for renal size during growth. METHODS: The data for renal length in 66 children (age, 12.9+/-15.6 months; male/female, 34/32) were obtained. Each kidney was measured with ultrasonography and dimercaptosuccinic acid scan. The data on age, sex, height, and weight were obtained from the medical records. BSA, BMI, and Rohrer and Kaup indices were calculated from measured height and weight. BSA was calculated by 2 methods, and is expressed as BSA I and BSA II. RESULTS: There were significant correlations between renal size and age, weight, height, BSA I, BSA II, and Rohrer index. In the regression analysis, the most significant contributing factor to renal growth was height (R2=0.636, P<0.001). CONCLUSION: Height seems to be the most important factor associated with organ growth in growing children. Further studies to evaluate adequate organ growth should be carried out.

PURPOSE: The primary objective of this study is to identify the changes in the birth weight of full term newborns in the Korean population over the past 5 years and to delineate their relating factors. METHODS: We used the dynamic statistics of the population from the Korea National Statistical Office which represents the current trend of social stratification. We analyzed birth records over a five-year period & studied the changes in the birth weight of full term newborns by year, gender, gestational age & Seoul or non-Seoul areas from 2002 to 2006. RESULTS: The mean birth weights of newborns in the 37~40 weeks range were 3,312 g and 3,210 g for male & female infants, respectively & decreased by 62 g and 49 g over the past five years. The birth weight in full term newborns decreased from 3,299 g to 3,243 g in total and there was no difference in the changes of birth weigh for each year, both sexes, each gestational age & capital or non-capital areas. CONCLUSION: The birth weight of full term newborns in Korea has decreased over the past five years, showing that there are no big differences between genders, gestational ages, and Seoul or non-Seoul areas. We need to study more prospectively the demographic variables which cause the trend if the mean birth weight continues to decrease.

Postoperative bleeding is a common complication in cardiac surgery using cardiopulmonary by- pass(CPB) and thrombocytopenia and platelet dysfunction, as well as inadequate surgical hemostasis are cited as a cause. To evaluate the effect of routine use of platelet to prevent postoperative bleeding, auther compared the patients with and without platelet administration of 1 unit/10kg. Routine coagulation tests(RCT) and Thromboelastographs were compared to evaluate the effects of CPB and platelet administration. Also postoperative bleeding amounts were compared. PT and aPTT of RCT were prolonged and fibrinogen was decreased after CPB with no effect with platelet administration. Platelet count was decreased after CPB and recovered in number reaching the pre-CPB level with platelet. R, K, and a of TEG parameters showed no differences after CBP even with platelet. MA, the index of platelet function, remained in the normal range and became hypercoagulable with platelet administration. There was no difference in bleeding amounts between two groups. According to the results, routine administration of platelet after CPB in cardiac surgery is not recommended.
