There is a great difference of opinion regarding the treatment of intraarticular fractures of the calcaneus. Many authors suggested that there are essentially four basic methods of treatment, but the choice of treatment depends on the surgeons preference, the type of fracture, and the age of the patient. We obtained the following results in 11 cases of calcaneal fractures involving subtalar joint which were treated by axial fixation at our hospital from 1977 to 1981. 1. The favourable results were obtained in 5 cases of 6 feet of tongue type fractures and in 3 cases of 5 feet of joint depression fractures. 2. Even if the joint depression type fracture which is not severely comminuted, the treatment with axial fixation is thought to be good method. 3. Axial fixation must be tried in three faces of reduction which are reestablishment of Bohler angle and subtalar joint and reduction of lateral bulging of calcaneus. The results were more excellent in which reduction is achieved near anatomical position.

PURPOSE: The purpose is to aid in the diagnosis and obstetric management by analysing the ultrasonographic findings of prenatally diagnosed Edward syndrome. METHOD: The study population consisted of 15 cases prenatally diagnosed Edward syndrome from January 1993 to January 1999. The medical charts and ultrasonographic findings were reviewed retrospectively, and especially the ultrasonographic findings before prenatal genetic diagnosis were anlyzed. RESULTS: All of the 15 cases reviewed showed at least one ultrasonographic finding suggesting Edward syndrome. In the first trimester, 2 cases revealed cystic hygroma and increased nuchal translucency, and after the second trimester, major structural anomalies including congenital heart anomalies and minor ultrasonographic findings such as choroid plexus cyst were noted. All of cases after 21 weeks of gestation showed congenital heart anomaly, and as the pregnancy progressed there was an increased tendency of intrauterine growth restriction and polyhydramnios. CONCLUSION: Prenatal ultrasonography in the screening process of Edward syndrome can be placed as a very informative method, as all of the Edward syndrome cases revealed at least one abnormal ultrasonographic findings. As congenital heart anomalies were found in all of the cases after 21 weeks of gestation, fetal echocardiography should be considered in evaluating suspected cases of Edward syndrome.

4.Cytogenetic study employing chorionic villi in ectopic pregnancy.
Yonsei Medical Journal 1995;36(5):438-447
Maternal factors such as salpingitis and peritubal adhesion are known to be associated with ectopic pregnancy; however, a few studies have considered the chromosomal complements of ectopic conceptuses. We studied 16 ectopic conceptuses obtained by surgical resection. The karyotyping of chorionic villi was performed using direct and culture technique. Among 16 studied cases, 14 cases showed normal karyotype (nine with 46, XY; five with 46, XX). One case showed trisomy 16(47, XY, + 16) and another showed variation from normal chromosomal complement (46, XY, 14s+), resulting in 6.3% incidence of the structural abnormalities of the chromosome. On the basis of our study, we determined the possibility of chorionic villi karyotyping in ectopic pregnancy. This ectopic conceptuses are no more likely to show chromosomal abnormalities than in utero conceptuses of comparable gestational age. Therefore, maternal factors such as salpingitis and peritubal adhesion are the most likely explanations for ectopic pregnancy.

A total of 48 subjects harbouring Trichuris trichiura, Ascaris lumbricoides, hookworm and/or Enterobius vermicularis were treated with oxantel/pyrantel pamoate tablets (100 mg of each) in a single dose of 20 mg base per kg of body weight. In all 37 cases of A. lumbricoides and 8 cases of A. duodenale infections cured completely, and the mean recovered worm-load was 3.8 with a range of 1-21 and 5.8 with a range of 3-9 respectively. In T. trichiura infection, 32(71.1%) of 45 cases cured completely and the average egg reduction rate was 90.8 per cent. The mean recovered worm-load was 14.6 with a rnage of 1-77 worms. On the other hand, in E. vermicularis infection, 37 (84.1 %) of 44 patients were negative eggs by anal swab tests on the 10 to 11th days and 27 (61.4%) on the 20 to 21st days after treatment. The mean recovered worm-load was 17.7 with a range of 1-62. Only one patient with Trichostrongylus orientalis treated with this drug showed no eggs in his stools throughout the post-treatment examinations. Side effects were not noted in all treated cases. These findings demonstrate that a single dose of oxantel/pyrantel pamoate tablets can be considered a drug of choice for multiple infections with these nematodes.

The author carried out a study on the effectiveness of the boric acid as a stomach poison for German cockroach control from July to September 1971. The test was performed by the feeding method under conditions of 20 C and 80 per cent relative humidity. The baits were composed of one control group and five different combination groups with boric acid and sugar as follows. 10 g sugar only(control group), 1 g powedered boric acid to 9 g sugar(1:9 poison baits), 2 g powdered boric acid to 8 g sugar(2:8 poison baits), 4 g powdered boric acid to 6 g sugar(4:6 poison baits), 5 g powdered boric acid to 5g sugar(5:5 poison baits), 10 g powdered boric acid only (10:0 poison baits). The insects were composed of 360 female adult German cockroaches collected by traps at the kitchens of restaurants and house holds in Seoul City. The results were as follows: The total mortality by poison baits in 72 hours after treatment were: 44.3 per cent by 1:9 poison baits , 79.4 per cent by 2: poison baits , 96.7 per cent by 4:6 poison baits(the most effective poison baits), 88.3 per cent by 5:5 poison baits, 91.1 per cent by 10:0 poison baits. The peak mortality by the treatment hours were: Up to 21 hours: 23.3 per cent by 5:5 poison baits, 20.0 per cent by 10:10 poison baits, From 24 to 48 hours: 71.1 per cent by 4:6 poison baits, 55.6 per cent by 10:0 poison baits, From 48 to 72 hours: 21.9 per cent by 2:8 poison baits, 19.6 per cent by 1:9 poison baits. The most effective treatment hours was from 24 to 48 hours.

This study was performed to compare and analyzed the mode of tooth movement according to the timing of orthodontic force application after extraction. The upper right and left third incisors were carefully extracted at three-week interval in four adult dogs. Both canines were used as an anchorage for the bodily movement of the upper second incisors. Orthodontic force of 100gm was simultaneously applied at one week after extraction on one side four weeks after extraction on the other side using NiTi closed coil spring. While orthodontic force was applied for twelve weeks, the amount of tooth movement was measured at every second week with calipers. The animals were sacrificed at twelve weeks and histologic examination was executed to reveal any difference between both sides. The results were obtained as follows: 1. The tooth movement was likely to be faster in four-week side for the first two seeks while faster in one-week side during next two weeks 2. The rate of tooth movement was fastest during four to six weeks period, then decreased gradually. 3. The total amount of tooth movement was likely to be larger in one-week side compared to four-week side. 4 Any damage to tooth and periodontal tissue could not be seen in the histologic section of one-week side. These results suggest that earlier application of orthodontic force is better than later after extraction in terms of the rate of tooth movement.

Purpose: The diagnostic usefulness of fetal echocardiography in congenital heart disease is well known. One of the indications for fetal echocardiography is presence of extracardiac anomalies and such coexistent congenital heart disease may have important implications for obstetric and neonatal management. MATERIALS AND METHODS: 496 women with singleton pegnancies with amgenital anomalies that underwent penatal care and follow-up in Severance Hospital for 5 years from 1991 to 1995 were evaluated for the incidence of congenital heart disease. RESULTS: The incidence of congenital heart disease in fetuses with the associated extracardiac anomalies were as follows; central nervous system 6.9%(11/160), gastro-intestinal system 10.7%(8/75), genito-urinary sysem 4.7%(4/85), others 5.6%(4/72). Thirty-one of eighty-ane fetuses with congenital heart disease were found to have the associated extracardidac anomalies and ten of them chenoscenal abnormalities. CONCLUSION: We recommend that fetuses with congenital extracardiac anomalies sbould be checked for the presence of congenital heart disease and chmmosomal abnormalities, if needed.

OBJECTIVE: The aims of this study was to examine whether epileptic women with antiepileptic drugs(AEDs) treatment during pregnancy were associated with an increased risk of adversed pregnancy outcome. METHODS: The study design was a retrospective analysis of 91 epileptic pregnant women attending the Severance Hospital Yonsei Medical Center between January 1980 and June 1998. Of the 91 women, data from 84 were available for analysis. Adverse pregnancy outcome in 66 women who were exposed to AEDs during pregnancy were compared with those of 18 controls who were not. The main adverse pregnancy outcome included spontaneous abortions, perinatal deaths, preterm deliveries, fetal growth restriction and congenital anomalies. RESULTS: Epileptic women with AEDs treatment during pregnancy were not significantly different from their controls in the incidence of spontaneous abortions(1.5% vs, 5.5%), perinatal deaths(1.5% vs. 0%), preterm deliveries(3% vs. 5.5%), fetal growth restriction(3% vs. 0%), and congenital anomalies(3% vs 5.5%). An adverse outcome occurred in 8 of 66 women(l2%) in the study group and 3 of 18 control group(16.5%). This difference was not statisitically significant. CONCLUSION: Our study shows that epileptic women who were exposed to AEDs during pregnancy do not have an increased risk of adversed pregnancy outcome than the women who were not.
