BACKGROUND: Computerized topography(CT) is the method of choice for establishing patients with abdominal and/or pelvic trauma. However, the sensitivity of CT far detecting bladder rupture has been questioned. We investigated the roles of CT as the initial evaluation of abdominal and pelvic trauma in diagnosis of bladder rupture. METHODS: We reviewed the medical records and radiographs of 53 patients with bladder rupture for last 5 year. And among them, all radiographs of 30 patients who underwent both CT and retrograde cystography were evaluated independently by two urologists who had no knowledge of the patients' final diagnosis. RESULTS: Among 30 patients, all of patients were correctly diagnosed by retrograde cystography, but the CT diagnosis was correct in only 23 patients(76.7%), who were 17 patients(85.0%) with intraperitoneal rupture and 6 patients(60%) with extraperitoneal rupture. And of the 7 patients who were negative by the CT, all showed the sign of inadequate bladder distension. CONCLUSION: We suggest that CT, if properly performed with adequate bladder filling, is as sensitive for detection of bladder injuries as conventional cystography. Especially, in trauma patients with hematuria and suspected other organ injury, CT-cystography with retrograde filing may be as accurate as conventional cystography and obviate the need for an additional plain film cystography,

STATEMENT OF PROBLEM: Proper proximal contact is important for maintaining and stabilizing the dental arch. However, the proximal contact strength (PCS) is not a constant value and can be affected by a variety of factors. PURPOSE: This study examined the influences of postural changes on the posterior PCS. MATERIAL AND METHODS: Twelve adults with a normal occlusion and had not undergone prosthetic treatment or proximal restoration were participated in this study. A metal strip was inserted into the proximal surface and removed at a constant velocity. The contact strength was measured in every contact point between canine to second molar in both arches. The PCSs were obtained initially in the upright position, secondly in the supine position and finally in the upright position again. All measurements were repeated after a 2 hour period. Statistical analysis was carried out using the Friedman test (P < .05). RESULTS: Generally, a decrease in PCS occurred when the posture was changed from the initial upright to supine position, while it increased when the posture was changed from the supine to upright position. A significant change was observed in all areas except for between the canine-first premolar in the maxilla and between the first molarsecond molar in the mandible areas. CONCLUSION: The posterior PCS, which dentists generally believe to be a static feature of occlusion, is affected significantly by posture.

BACKGROUND: Recently, it has been established that plateletpheresis needs more efficiency and shorter processing time. Fenwall laboratories developed a new collection chamber for CS-3000 Plus, PLT-30TM collection chamber, which can reduce the processing time with efficient collection. We evaluated the PLT-30TM collection chamber by comparing it with A-35 collection chamber that has been used as a standard collection chamber of CS-3000 Plus us. METHODS: Thirty platelet collection procedures were performed using the CS 3000 Plus with A-35 collection chamber and PLT-30TM collection chamber. The changes of the hematologic parameters between pre- and post-donation in donors and the total platelets yields and the contaminated WBCs in the plateletpheresis products were evaluated. In processing, the yield predictor calibration was adjusted to 1.00 and 1.13 in A-35 and PLT-30TM respectively. Yield predictors of pheresis were the same as 3.5x1011 in both and end point volumes were calculated from the CS-3000 Plus. Processing volume and processing times were compared between A-35 and PLT-30TM groups. RESULTS: With PLT-30TM collection chamber, 3.38+/-0.72x1011/L platelets were harvested, whereas 3.20+/- 0.73x1011/L were collected with A-35 collection chamber, which was not significantly different. But processing time with the PLT-30TM collection chamber was more reduced than that with the A-35 collection chamber by about 20 minutes (PLT-30TM : 88.6+/-8.4 min, A-35 : 106.7+/-11.7min). Collection efficiency of PLT-30TM chamber was 50.7+/-12.5% and that of A-35 chamber was 44.4 + 8.8%. The leukocyte contamination of the platelet concentrates were not statistically different(PLT-30TM: 0.0-3.6x106, A-35 : 0.1-4.1x106). CONCLUSIONS: PLT-30TM collection chamber has the advantages of shortening the donation time and decreasing the processing volume with better collection efficiency and flexibility of platelet concentrate volume.

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.

PURPOSE: Febrile seizures(FS) are the most common form of childhood seizures and their prognosis are favorable. Despite the fact, there are still some concerns that prolonged febrile seizures may cause brain damages or neurological sequelae, which may be associated with the development of mesial temporal sclerosis and intractable temporal lobe epilepsy in later life. The aim of this study was to evaluate the clinical characteristics and outcomes in children with febrile status epilepticus(FSE). METHODS: 39 children aged 6 months to 5 years were enrolled in this study, who presented with FSE at Kyungpook National University Hospital, from January, 2000 to December, 2004. They were compared with 250 children who presented with the first episodes of FS at the same period. We reviewed retrospectively the medical records for the clinical characteristics and outcomes of the two groups. RESULTS: There were no statistically significant differences between the two groups in terms of age, etiology, degree and duration of fever, type of seizure, family history of FS or epilepsy, EEG and MRI findings, and recurrence rates of FS. Children with FSE were more likely to have neurological sequelae(12.5% vs. 2.4%; P=0.008), to develop afebrile seizures(21% vs. 4%; P=0.00) and to take anticonvulsants chronically(33% vs. 2%; P=0.00) than children with FS. CONCLUSION: Our results indicate that prolonged febrile seizures are associated with unfavorable neurological outcomes compared with simple febrile seizures. However, long-term, and extensive follow-up studies are needed to find out the relationship between prolonged febrile seizures and subsequent mesial temporal sclerosis as well as intractable temporal lobe epilepsy.

The incomplete obliteration of the processus vaginalis leads to the development of inguinal hernia in pediatric age, and its management is principally surgical repair. This study was a review and analysis of the usefulness of herniography on the hydrocele in pediatric age. From January 1985 to June 1989, 117 patients with unilateral hydrocele were studied to evaluate incomplete obliteration of the processus vaginalis. The over-all incidence of open processus vaginalis on the opposite side was 6.9% (8 of 117 cases), but the rate of patients who had past history of a palpable or visualized mass on the opposite side was 5%(3 of 12 cases). This finding would suggest that the herniogram is needed for the patients whose history is suspicious for hydrocele testis.

PURPOSE: The purpose of this study was to analyze differences in health behaviors among adolescents in order to provide fundamental data to develop an effective body weight control program. METHODS: Secondary analysis was done using data from the 9th (2013) Online Survey on Ado-lescents' Health Behaviors by the Korea Centers for Disease Control and Prevention. The adolescents were divided into low weight, normal weight, overweight, and obesity groups according to body mass index (BMI). Differences in health behaviors were analyzed. RESULTS: Gender, grade, socioeconomic status, perceived-health status, exercise, breakfast, fast food, ramen noodles, snacks, carbonated soft drinks, fruits and vegetables, satisfaction with sleep, stress, smoking, and alcohol consumption were significantly different among the groups. Ingestion of carbonated soft drinks and snacks was significantly higher in the low weight group compared to the normal weight group. Eating fast foods, ramen noodles, and snacks was significantly lower in the overweight and obesity groups compared to the normal weight group. CONCLUSION: Findings indicate that health behaviors among the groups differ from traditional knowledge about obesity. To develop optimal programs and improve efficacy, prior knowledge should be used to think differently and individualized programs should be based on an understanding health behaviors of adolescents.

OBJECTIVE: The study was conducted to calculate the heterozygote frequencies of factr VIII gene in Korea, using two PCR-RFLPs(intron 18-Bcl I ploymorp[hism and intron 19-Hind III polymorphism). STUDY DESIGN: Twenty six women and five men were examined. Each segment of genomic DNA in intron 18 and intron 19 was amplified with polymerase chain reaction, digested with the Bcl I and Hind III, respectively. The heterozygote frequencies were calculated from the allele frequencies observed in each PCR-RFLP. RESULTS: The Bcl I polymorphism of the factor VIII gene was detected on agarose gel as segments of 434 bp and 286 bp/148 bp, respectively,The heterozygote frequency calculated from the allele frequencies(0.75/0.25) observed in intron 18-Bcl I polymorphism was 38%. In case of intron 19-Hind III polymorphism, two allele system with polymorphic bands of 250 bp and 160 bp/;90 bp was detected on polyacrylamide gel. The heterozygote frequency calculated from the allele frequencies(0.81/0.19) observed in intron 19-Hind III polymorphism was 31%. Thus, the two intragenic polymorphism predicted to be informative was 57% in this study. CONCLUSION: Multipoint linkage analysis using multiple PCR-RFLP provides highly useful method for the detection of the heterozygote of factor VIII gene.
