Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder and is essentially a disorder of capillary, venous, and lymphatic malformations. Hematochezia is the most common symptom associated with intestinal hemangiomatosis and remains one of the life-threatening emergencies in KTS. We reported one patient of KTS presented with rectal bleeding and severe anemia who was successfully managed by sphincter-saving operation.

PURPOSE: To evaluate the impact of temporary internal ureteral stents on the surgical outcomes of dismembered pyeloplasty in children. MATERIALS AND METHODS: The medical records of 70 children (76 renal units) who underwent dismembered pyeloplasty for ureteropelvic junction (UPJ) obstruction at at Asan Medical Center between January 2005 and December 2010 were retrospectively reviewed. We classified the renal units into the stented group (22 renal units) and the nonstented group (54 renal units). Fifty-four of 70 patients were male and their mean age was 2.2+/-3.8 years old. The mean follow-up period was 29.6+/-16.8 months. RESULTS: Sixty-four children had unilateral UPJ obstruction. The mean stent duration was 31.9 days. As shown by evaluation of radiologic images, there were no significant differences between the stented group and the nonstented group during the follow-up period (p>0.05). The mean preoperative and postoperative anteroposterior pelvic diameters (APPDs) of the nonstented group were 31.3 mm and 15.1 mm, respectively (p<0.001). The preoperative and postoperative grades of hydronephrosis were 3.9 and 2.9, respectively (p=0.037). The mean preoperative and postoperative APPDs of the stented group were 36.4 mm and 15.6 mm, respectively (p<0.001). The preoperative and postoperative grades of hydronephrosis were 4 and 3.1, respectively (p<0.001). Repeat obstruction was shown in 4 subjects as a postoperative complication (5.7%). Two children from each group had recurrent UPJ obstruction, with percentages of 3.7% and 9%, respectively (p=0.575). CONCLUSIONS: In a comparison of nonstented and stented groups during pediatric dismembered pyeloplasty for UPJ obstruction, no significant differences were found in the resolution of hydronephrosis or overall postoperative complications.

This study was condicted to construct a hypothetical model of depression in Korean adolescent women and validate the fit of the model to the empiricla data. The data were collected from 345 high school girls in Seoul, from May 1 to June 30, 1998. The instruments were the Body Mass Index, Physical Satisfaction Scale, Family Adaptatibility and Cohesion Evaluation Scale III, Family Satisfaction Scale, CES-D and School Adaptation Scale. The data were analyzed using descriptive statistics with the pc-SAS program. The Linear Structural Relationship(LISREL) modeling process was used to find the best fit model which would predict the causal relationships among the variables. The overall fit of the hypothetical model to the data was moderate [X2=69.6(df=17, p=.000), GFI=0.95, AGFI=0.90, RMR=0.087, NNFI=0.86, NFI=0.90]. The predictable variables, especially menstrual symptoms, physical symptoms and family function, had a significant direct effect on depression, but school life adaptation did not have a significant direct effect. These variables explained 18.1% of the total variance.

PURPOSE: This study was designed to determine the predictors of postpartum depression. METHOD: One hundred- sixty one women within one year after delivery from one public health center located in the northern area of Seoul were used in this study. The instruments were a survey of general characteristics, the Edinburgh Postnatal Depression Scale, recent life events index, perceived social support from family, Quality of marriage index, parenting stress index, and Rosenberg's self-esteem inventory. Data was analysed using descriptive statistics, Pearson correlation coefficients, and logistic regression. RESULT: The average item score of the EPDS was 6.67. 12.4% of respondents, who scored above a threshold 12, were likely to be suffering from a depression of varying severity. The fitness of the model for explaining postpartum depression from six variables, plan for pregnancy, family support, quality of marital relation, perceived social support, life events, childcare stress, and self-esteem, was statistically significant and the predictive power of these variables was 90.9%. The significant predictors of postpartum depression were family support and child care stress. CONCLUSION: Further research is needed to identify the prevalence rate of postpartum depression using more reliable sampling methods from a large general population. Nursing interventions need to be developed for promoting family support and reducing childcare stress.

Anodic spark deposition method(ASD) surface treated titanium implant possesses a considerable osteoconductive potential that promoting a high level of implant osseointegration in normal bone. The purpose of this study was to observe the ASD implant's osseointegration in the osteoporosis-induced animal model. Twenty four rats, 10 weeks of age, were ovarectomized and 5 weeks later divided into two groups : ASD implant group and control implant group. Titanium screw implants (diameter; 2.0 mm, length, 3.5 mm; pitch-height, 0.4 mm) were designed for this study. Experimental implants were ASD treated and no treatment on control implants. ASD implants and control implants were placed in to left tibiae of rats. The rats were sacrificed at different time interval(1, 2, 4 and 8 weeks after implantation) for histopathologic observation and immunohisto -chemistrical observation, with collagen type I, fibronectin, integrin alpha2beta1 and integrin alpha5beta1 antibodies. The results obtained from this study were as follow: 1. Histopathologic findings, overall tissue response and the pattern of bone formation in both groups were similar. In ASD group, more newly formed bone was seen at 1 week and 2weeks than control group. 2. The levels of type I collagen and fibronectin expression were the most abundant at 2weeks and decreased gradually in both groups. Fibronectin and type I collagen expression in ASD group were stronger than control group but no significance. 3. The levels of integrin alpha2beta1 and Integrin alpha5beta1 expression were most abundant at 2 weeks and decreased gradually in both groups. No significant difference was observed in both groups. From this results, anodic oxidized titanium implants were more advantages in early stage of bone formation than control group, but have no significance in tissue responses and late bone formations. It could be stated that although anodic oxidized titanium implant possesses considerable osteoconductive potential but in osteoporotic bone condition dental implant procedure should performed after improving or treating the osteoporotic bone condition.

Cell-matrix interactions have major effects upon phenotypic features such as gene regulation, cytoskeletal structure, differentiation, and aspects of cell growth control. Upon detachment from the matrix epithelial cells enter into programmed cell death and this cell detachment-induced apoptosis has been referred to as "anoikis". This study was undertaken to determine whether apoptosis is induced by inhibition of contact with extracellular matrix in mouse inner medullary collecting duct cells (mIMCD-3), what are signaling mechanisms of the process and whether EGF protects detachment-induced apoptosis. Upon detachment from the extracellular matrix, MDCK and mIMCD-3, which were derived from inner medulla of SV40 transgenic mouse, entered into programmed cell death as a time-dependent manner. Apoptotic cell death induced by cell detachment increased in serum-free medium, which was partly protected by the addition of epidermal growth factor (EGF). Ly294002 and wortmannin, inhibitors of phosphatidylinositol 3-kinase (PI 3-kinase), negated the EGF effect, whereas PD98059, a MEK inhibitor, did not. The addition of SB203580, an inhibitor of p38 kinase, did not protect apoptosis in suspended mIMCD-3 cells. These results indicate that apoptosis is induced by inhibition of contact with extracellular matrix in mouse inner medullary collecting duct cells and that PI 3-kinase, not MAPK, is a key mediator of the EGF-induced survival of renal epithelial cells in the absence of attachment.

PURPOSE: To compare the precise roles of high-resolution computed tomography (HRCT) and fiberoptic bronchoscopy (FOB) in the evaluation of patients presenting with hemoptysis and to determine the optimal timing for HRCT. MATERIALS AND METHODS: The results of HRCT and FOB were compared in 23 patients (15 men, 8 women) presenting with hemoptysis. Etiologies included bronchietasis (n=4), parenchymal pulmonary tuberculosis (n=4), lung cancer (n=4), endobronchial tuberculosis (n=2), and broncholithiasis (n=2). Hemoptysis was proved to be due to miscellaneous causes in an additional three cases and to be cryptogenic in four. The diagnostic results of FOB performed before and after HRCT were compared as were those of HRCT performed within and after the first 48 hours of active bleeding. RESULTS: FOB and HRCT offered a correct diagnosis in 39% and 65% of cases, respectively (p=0.005). HRCT demonstrated three cases of bronchiectasis and three of parenchymal pulmonary tuberculosis which were beyond the range of a bronchoscope. In two of five cases in which HRCT findings were nonspecific, chondromatous hamartoma and lung cancer were confirmed by FOB. In cases where HRCT was performed prior to FOB, the latter demonstrated the location and diagnosis in 82% and 47% of cases, respectively (p=0.303) ; when HRCT was performed after FOB, HRCT was correct in 67% and 17% of cases, respectively (p=0.178). In none of three cases (0%) in which HRCT was performed during the first 48 hours of active bleeding did the procedure allow a specific diagnosis. In 15 of 20 (75%) cases in which HRCT was performed after the first 48 hours, however, the diagnosis provided by CT was correct. CONCLUSION: The results of this study suggest that in patients presenting with hemoptysis, both HRCT and FOB should be used for evaluation, since they are diagnostically complementary. FOB is more useful for the diagnosis of endobronchial lesion, and HRCT for bronchiectasis and parenchymal pulmonary tuberculosis. If, in cases of hemoptysis, initial diagnosis is attempted within the first 48 hours of active bleeding, FOB should be the initial step, and HRCT images should not be obtained until active bleeding has been shown on plain chest radiograph to have abated. If this initial approach takes place after the first 48 hours of active bleeding, FOB and HRCT are equally suitable.

OBJECTIVES: The objective of this study is to analyze 1,068 cases of prenatal genetic amniocentesis and to compare the results with reported studies. METHOD: We analyzed 1,068 cases of midtrimester prenatal genetic amniocenteses from September 1994 to February 1999, and investigated the fetal chromosomal abnormality, obstetric outcomes and complications by the indications of genetic amniocentesis and prophylactic antibiotic use at the Department of Obstetrics and Gynecology, Ajou University School of Medicine. RESULTS: Abnormal maternal serum markers were the most common indication of amniocentesis (57.7%) and the most common age distribution was 25-29 years (39.2%). One case of early amniocentesis (14 gestational weeks) was performed. The overall incidence of chromosomal aberration was 5.2% (56/1,068), of which there were 28 cases (50.0%; 28/56) of numerical aberrations and 28 cases (50.0%; 28/56) of structural aberrations. There were 50 cases (4.7%) of autosomal chromosomal aberrations and 6 cases (0.6%) of sex chromosomal aberrations. The pregnancy outcome was full-term delivery in 86.5%, preterm delivery in 7.6%, termination of pregnancy in 4.0%. There were no cases of serious complications including fetal death except for a case of self-limited amniotic fluid leakage(high leakage) in which the pregnancy was maintained. There were no significant differences between prophylactic antibiotics user group and non-user group in obstetric complications and outcomes. CONCLUSION: We could confirm that the trend in the indication of genetic amniocentesis had changed from advanced maternal age(35 year-old) toward abnormal maternal serum marker(triple test), and we recognized the importance of genetic amniocentesis according to the various antenatal screening tests of maternal serum marker, antenatal ultrasound, past history of fetal anomaly or family history of fetal chromosomal anomaly in the younger age groups(< 35 year-old) that are involved in more than half of the chromosomal anomaly. Further study will be needed to elucidate the efficacy of using prophylactic antibiotics in amniocentesis.
