In clinical practice, creatinine clearance (Ccr) remains the most commonly used laboratory assessment of glomerular function despite methodological and technical problems of urine collection. Schwartz et al. in 1976, reported that an accurate estimate of glomerular filtration rate (GFR) could be obtained from the simple determinations of plasma creatinine (Per) and body length (L): GFR (ml/min/1.73m2)=kL (cm)/Per (mg/100 ml), (k=constant). The subject of this study were 81 children admitted to our pediatric department from July, 1985 to June, 1987 and they were divided into three groups; group I, from 1 to 5 years old, group II, from 6 to 10 years old, group III, from 11 to 15 years old. The results were as following: 1) Measured creatinine clearance Ccr(M), ml/min/1.73m²) were 109.73±9.97 in group I, 108.26±9.02 in group II, 96.20±4.72 in group III and 105.48±5.23 in all age group. 2) Measured k(k(M)) obtained from CcrM=k Ht/Pcr were 0.49±0.03 in group I, 0.48±0.02 in group II, 0.43±0.02 in group III, and 0.47±0.02 in all age group (Ht; height). 3) Linear equations and correlation coefficient between Ht/Pcr (x) and Ccr (y) were y=0.82x-65.63 (r=0.99) in group I, y=0.61x-23.46(r=0.72) in group II, y=0.18x+54.44 (r=0.54) in group III and y=0.58x-22.13 (r=0.81) in all age group. 4) Ccr(E) was again estimated from linear equations between Ht/Pcr and Ccr(M) and k(E) was calculated with Ht/Pcr and Ccr(E) were 0.48±0.01 in group I, 0.49±0.01 in group II, 0.43±0.01 in group III and 0.47±0.00 in all age group. 5) Consistent values of k(E) and k(M) were highly significant as 95~97.5% in group I and II, 90~95% in group III and 97.5~99% in all age group. In summary, we could estimate GFR with height, plasma creatinine and measured k(k(M)) according to the age in easy and rapid way.

To make better clinical diagnosis, authors reviewed 9 patients of nonchromosomal multiple malformation disorders with psychomotor retardation, who were evaluated at pediatric department of Yeungnam University hospital for recent 2 years. We could make clinical diagnosis in 5 patients out of 9 as Aarskog syndrome, BeckwithWiedemann syndrome, Hallermann-Streiff syndrome, Rubinstein Taybi syndrome and Weaver syndrome. But even in diagnosed cases, there were many discrepant findings in comparison with typical cases of reference literatures and family history was positive in only one case. Moreover we could not make diagnosis in 4 patients. Therefore we think it is necessary to make a survey of unique pattern, incidence, distribution and etiologic factors of malformation disorders in our country by geneticist and pediatrician as well as to improve the laboratory aids for better diagnosis and genetic counseling.

The systemic lupus erythematosus is a self-perpetuating disease with multisystem involvement, i.e.; skin, kidney, serous membrane, nervous system and other organs. The mortality in SLE is determined primarily by the extent of renal involvement and the degree of immunosuppression resulting from the therapy. We experienced two cases of lupus nephritis in SLE with clinical, serologic, immunologic and pathologic evaluations. Renal biopsy revealed focal and segmental proliferative glomerulonephritis and mesangial proliferative glomerulonephritis. Both patients have been improving with prednisolone on follow-up studies.

OBJECTIVE: Our purpose was to evaluate the effect of epidural anesthesia on labor course. METHODS: Between January 1998 and December 1998, we evaluated pregnant women at term with singleton fetus in vertex presentation and with spontaneous onset of labor at our hospital. Comparison of 120 women (100 cases of primiparous women, 20 cases of multiparous women) who received epidural anesthesia in labor with 120 women (100 cases of primiparous women, 20 cases of multiparous women) who did not receive epidural anesthesia was performed. Adverse pregnancy outcomes were obtained from hospital delivery records and neonatal records. Statistical analysis were performed by Student's t-test and Chi square test. RESULTS: The results of this study were as followings; 1. There was no significant difference in mean age, body weight, height, and gestational age between epidural anesthesia group and control group (P>0.05). 2. The frequency of oxytocin augmentation was significantly greater in the primiparous epidural anesthetic group than in primiparous control group (p<0.05). 3. The effect of epidural anesthesia on the first stage of labor revealed no significant difference in both group. 4. Prolongation of second stage of labor was noticed in nullipara of epidural anesthesia group compared to control group (p<0.05). 5. The incidence of instrumental delivery was significantly increased in the primiparous epidural group than in the primiparous control group(p<0.05). 6. The meconium-stained amnionic fluid, Apgar score and birth weight were similar in both groups. 7. The maternal blood loss was similar in both groups. CONCLUSION: Epidural anesthesia, significantly prolongs second stage of labor in induced patients. While instrumental delivery was more prevalent in these parturients, C-section rate and intra-partum complications were not increased in these patients.

OBJECTIVE: Our purpose was to assess the efficacy of routine ultrasonographic prediction of macrosomic fetal weight, to determine its influences on subsequent delivery type and to assess perinatal outcome by delivery type. METHODS: The hospital records of 177 patients delivered infants weighing > or =4000gm between January 1997 and December 1998 were reviewed. Statistical comparisons were made between patients in whom fetal macrosomia was predicted before delivery(n=71) and those in whom it was not(n=106) and between the perinatal outcomes for macrosomic fetuses delivered vaginally and by cesarean section. The statistical analysis was performed by student-t test, and Chi-square test and Fisher's exact test. RESULTS: The fetuses were consecutive singleton fetuses in vertex presentation delivered at a single institute. The sensitivity for identifying macrosomic fetus(birth weight >4000gm) with an estimated weight of > or =4000gm was 40%, Overall 60% of the infants had birth weights within 10% of the ultrasonographic estimates and 29% had birth weights within 5% of the ultrasonographic estimates. Cesarean sections were performed in 69% of the 'predicted' group and in 35% of the 'not predicted' group(69% vs 35%, p<0.0001, Fisher's exact test). Predicated group were more likely to be performed by elective cesarean section(48% vs 19%, p<0.0001, Fisher's exact test) and more like due to failed progress at<4cm cervical dilatation(27% vs 7%, p<0.05, Fisher's exact test). The proportion of patients delivered by cesarean section for failed progress at > or =4cm cervical dilatation was similar in the predicted and not predicted groups(19% vs 12%, NS). There was no significant difference in the incidences of the occurrence of birth trauma. CONCLUSION: There appears to be a limitation to obtain estimation of fetal weight by ultrasonography. The antenatal prediction of fetal macrosomia is associated with a marked increase in cesarean deliveries without a significant reduction in the incidence of fetal injury

PURPOSE: Lipiodol CT is a important modality for the diagnosis of hepatocellular carcinoma and compared is usually performed at 2-3 week after Lipiodol injection. Therefore, we assessed and the diagnostic value and merits of immediate CT after chemoembolization from there of 2-3 week delayed Lipiodol CT. MATERIALS AND METHODS: Thirty three cases of chemoembolization which were performed both immediate CT after chemoembolization and 2-3 week delayed Lipiodol CT were reviewed retrospectively. They were divided into four grades according to pattern of lipiodol uptake by three radiologists. The diagnostic value of immediate Lipiiodol CT was compared to delayed Lipiodol CT. RESULTS: Grade 0 was two cases(3.0%) and Grade 1 was seven cases(21.2%). In the cases of Grade 2(23/33, 69.7%) tumor uptake could be dishng wished from parenchymal uptake of Lipiodol by its density and pattern. Tumor uptake showed dense and homogeneous pattern, but parenchymal uptake revealed less dense and hepatoram-like wedge shaped pattern. Lipiodol uptake of tumor in Grade 3(1/24, 3.0%) was equal to that in delayed Lipiodrl CT. Grade 3 and 2(72.7%) of the immediate Lipiodol CT were not inferior to delayed Lipiodol CT in its diagnostic value. CONCLUSION: The immediate Lipiodol CT could make rapid establishment of treatment plan and are expected to be more convenient than delayed CT for the patients.

OBJECTIVES: Considerable variations in the contents of clinical practice are the natural consequences of the fact that so many factors can have influences on each clinical decision making processes in the psychiatric treatment, let alone the pharmacotherapy of schizophrenia. To attain the goal of rational treatment, it is needed to examine the actual contents of clinical practices and the degree of variations among diverse hospitals. In addition, it is also needed to look into the unique situations in which each hospital is situated. For this purpose, this study tried to investigate the degree of variations in several aspects of the treatment of schizophrenia with atypical antipsychotics currently practiced in Korea. METHODS: This study is based on the data from RODOS (Risperidone Olanzapine Drug Outcome Study) in Korea. This study had been designed as a multi-center naturalistic study, therefore, had many advantages for the survey study of actual clinical practices. The subjects of the study were the in-patients who had been given risperidone or olanzapine for the control of their psychotic symptoms. Clinical data had been gathered by retrospective chart review. The degree and the characteristics of the variations were examined by comparing the patient-characteristic variables and the treatment-related variables among each hospital. RESULTS: The differences in the baseline characteristics of the patients including the duration of illness and the past history of psychiatric treatment were substantial among each hospital, and these differences seemed to explain a great portion of the variations in the contents of treatment. The variations in the dosage of risperidone and olanzapine were not conspicuous among each hospital. However, the variations in other treatment-related variables, including duration of admission, proportion of combined therapy with other antipsychotics, usage of anticholinergics, detection rate of extrapyramidal symptoms, remained statistically significant after adjusting the baseline patient characteristics as covariates. Although no significant correlation among each variable was found, a couple of unique practice patterns common to several hospitals could be observed. CONCLUSIONS: Considerable variations in the diverse treatment-related variables were observed in the treatment of schizophrenic patients with risperidone and olanzapine. It seemed that the major portion of these variations could be explained by the characteristic of patient group. However, the possibility remained that the other factors including the socio-cultural environment of the community and the disposition of the clinician themselves were still the major contributing factors to these variations. It is expected that the future clinical practice surveys like this study can help the clinicians to reevaluate their current practices, and can help to accumulate the basic data needed to establish the more rational and customized treatment practices.
