Clinical observation was made on 131 cases of the unstable spine injury treated at the Orthopedic Surgery Department of Busan National University Hospital during the period from January 1974 to December 1981. The results obtained were as follows: 1. More than two-thirds of patients were between the age of 20 and 40, and the proportion of males to females showed a ratio of 5.9 to 1. The most common cause of injury was falling at an industrial area, rating 64.1% of all cases. 2. Fracture level was observed 31.3% in the first lumbar level, 24.4% in the twelfth thoracic vertebra, and 67.9% between the twelfth thoracic vertebra and the second lumbar vertebra. 3. Mechanisms of injury were 44.3% by pure flexion, 26.7% by flexion and rotation, 15.3% by direct shearing force, and 13.7% by vertical compression. 4. The fracture with lower extremity paralysis was due to the rotational fracture dislocation, which comprised 66% of all. 5. Kyphosis increased to the average of 10.6 degree in the case of decompressive laminectomy and of 3.4 degree in the case of spinal fusion. 6. The anatomical alignment and a definite stability could be obtained by the use of Harringtons rod in the cases of the unstable thoracolumbar fracture and fracture-dislocation. In 3 cases of all, we could get satisfactory results 1 month after the day injury occured. 7. In case of complete paralysis of lower extremity, it was found only 9.4% showed partial recovery, neurologically, and 61.9% of the patients with incomplete paralysis were also partly recovered. 8. The most common complication was urinary tract infection, which comprised 83% of the cases. With the use of intermittent urinary catheterization, the voiding reflex recovered within 4 months in most cases.

OBJECTIVE: To validate quantitative fluorescent polymerase chain reaction (QF-PCR) via chorionic villus sampling (CVS) for the diagnosis of fetal aneuploidies. METHODS: We retrospectively reviewed the medical records of consecutive pregnant women who had undergone CVS at Cheil General Hospital between December 2009 and June 2014. Only cases with reported QF-PCR before long-term culture (LTC) for conventional cytogenetic analysis were included, and the results of these two methods were compared. RESULTS: A total of 383 pregnant women underwent QF-PCR and LTC via CVS during the study period and 403 CVS specimens were collected. The indications of CVS were as follows: abnormal first-trimester ultrasonographic findings, including increased fetal nuchal translucency (85.1%), advanced maternal age (6.8%), previous history of fetal anomalies (4.2%), and positive dual test results for trisomy 21 (3.9%). The results of QF-PCR via CVS were as follows: 76 (18.9%) cases were identified as trisomy 21 (36 cases), 18 (33 cases), or 13 (seven cases), and 4 (1.0%) cases were suspected to be mosaicism. All results of common autosomal trisomies by QF-PCR were consistent with those of LTC and there were no false-positive findings. Four cases suspected as mosaicism in QF-PCR were confirmed as non-mosaic trisomies of trisomy 21 (one case) or trisomy 18 (three cases) in LTC. CONCLUSION: QF-PCR via CVS has the advantage of rapid prenatal screening at an earlier stage of pregnancy for common chromosomal trisomies and thus can reduce the anxiety of parents. In particular, it can be helpful for pregnant women with increased fetal nuchal translucency or abnormal first-trimester ultrasonographic findings.

OBJECTIVE: To determine the risk of Down syndrome in fetuses with sonographic markers using the likelihood ratios and individual risk assessment. METHODS: We retrospectively evaluated the midtrimester genetic sonographic features of fetuses with Down syndrome and compared them with euploid fetuses. Patients were referred for an increased risk of aneuploidy and evaluated for the presence of structural defects, a nuchal fold, short long bones, pyelectasis, brachycephaly, small stomach, and hyperechoic bowel. Outcome information included the results of genetic amniocentesis (if performed), the results of pediatric assessment, and follow-up after birth. The sensitivity, specificity, and likelihood ratios for markers ware calculated isolated findings. RESULTS: There were 59 fetuses with Down syndrome and 600 euploid fetuses. The presence of any marker resulted in sensitivity for the detection of Down syndrome of 86.4% with a false-positive rate of 13.6%. Structural defect had a likelihood ratio of 77.8. As an isolated marker, the nuchal fold, short humerus, short femur, echogenic bowel and renal pyelectasia has a likelihood ratio of 20.2, 12.7, 3.9, 2.5, 1.1 respectively. Other isolated markers had low likelihood ratios because of the higher prevalence in the unaffected population. CONCLUSION: Combining second-trimester serum testing and fetal sonography is a feasible approach to Down syndrome screening, compatible with current obstetric practice. Although an isolated marker with a low likelihood ratio may not increase a patient's risk of Down syndrome, the presence of such a marker precludes reducing the risk of aneuploidy. This information will be useful in counseling pregnant women who are at high risk for fetal Down syndrome and who prefer to undergo genetic sonography before deciding about genetic amniocentesis.

OBJECTIVE: To evaluate the relationship between increased nuchal translucency (NT) and abnormal pregnancy outcomes. METHODS: From January 1999 to December 2001, The 298 fetuses of increased nuchal translucency (>or=2.5 mm) in period of 10-14 weeks gestation were reviewed retrospectively. Amniocentesis and high resolution ultrasonography during second trimester were done for all cases. We analyzed septation within NT, karyotypes, structural anomalies, and adverse pregnancy outcomes such as spontaneous abortion, intrauterine fetal death and preterm delivery. RESULTS: The mean age of the patients was 30.5 +/- 3.5 years. The mean gestational age and CRL were 12.5 +/- 0.95 weeks and 6.5 +/- 1.15 mm. We observed 18 (6%) cases of abnormal karyotypes. 7/46 (15.2%) fetuses with internal septation had abnormal karyotype and 11/252 (4.4%) fetuses without internal septation had abnormal karyotype (p=0.013). Among the 280 fetuses with normal karyotype, 8 (2.8%) fetuses had structural anomalies and 18 (6.4%) fetuses had adverse pregnancy outcomes. The chromosomal abnormality and structural anomaly were significantly increased in the group of nuchal translucency thickness above 3.5 mm (p=0.001). CONCLUSION: Increased nuchal translucency is related with chromosomal abnormality and abnormal pregnancy outcomes.

OBJECTIVE: This study is performed to assess whether detection of phosphorylated insulin like growth factor binding protein-1 (phIGFBP-1) in cervical secretions by a bed side test could be used to prediction preterm delivery in patient with regular uterine contraction. METHODS: In our prospective study, 42 women between 20.2 and 36.4 weeks gestation with regular, persistent contraction (2-3/min for 30 min). and 27 women between 22.0 and 37.0 weeks of gestation without symptoms of preterm labor were assessed for presence of cervical phIGFBP-1. Dacron swabs were applied to the cervix and assayed in 5min by using immunochromatography, actim partus test (Medix Biochemica). RESULTS: Of the 42 patients with regular uterine contractions, 22 had a positive actim partus test and 20 had a negative test. Among the 22 patients with positive test, 5 delivered preterm and other 17 patients delivered term (<37 weeks). Among the the 20 women with a negative test, 2 delivered preterm (NS). The mean concentration of phIGFBP-1 in 22 positive patients is 83.8+/-86.5 microgram/L and that in 20 negative patients is 2.1+/-5.0 microgram/L (P<0.0001) (Table 4). Sensitivity, specificity, false positive, false negative, positive predictive, and negative predictive values were 18.5, 59.6, 40.3, 28.6, 16.7, and 94.9%, respectively. CONCLUSION: The absence of cervical phIGFBP-1 is seems to be a valuable test in excluding preterm delivery in patients who have regular uterine contractions. The high negative predictive value in this study may enable physicians to prevent over treatment of patients with uterine contractions. Therefore, many unwanted side-effects and complications of potentially hazardous tocolytic therapy can be prevented.

OBJECTIVE: To compare the risk of congenital anomaly after exposure to suspected teratogens in early pregnancy with the known baseline risk to the geneneral population. METHODS: From September 1999 to August 2001, we counseled about the teratogenic risk of the fetus by relevant medical literatures after assessment of type, amount, and time of exposure for 302 pregnant women exposed to suspected teratogens such as drugs, radiation, alcohol, and cigarette smoking. We followed up on the pregnancy outcome with the rate of termination of pregnancy and incidence of congenital anomaly. RESULTS: Among a total of 302 cases, 253 pregnant women (83.8%) delivered, 15 (5%) were aborted spontaneously, 34 (11.3%) were terminated. 297 pregnant women (98.3%) were lastly exposed to drugs in mean 5.3 +/- 0.2 gestational weeks. Medicines taken were gastrointestinal drugs (23%), NSAIDs (18.3%), antibiotics (16.2%), antihistamines (10.8%) in the order of frequency. 74 pregnant women (24.5%) were exposed to radiation in mean 5.1 +/- 0.5 gestational weeks. The mean dose was 234.60 mrem. 113 pregnant women (37.3%) lastly drank alcohol in mean 4.5 +/- 0.4 gestational weeks and the mean amount was 1.55 oz. 36 pregnant women (11.9%) lastly smoked in mean 4.4 +/- 0.3 gestational weeks and the mean amount was 7.3 cigarettes/day. We found structural anomalies in 5 cases (Polydactylyl, Ileal agenesis, Both ear mass, Left ectopic kidney, Meningomyelocele) and 1 chromosomal abnormality case (Trisomy18). CONCLUSION: The rate of fetal structural anomaly was 2% in this study and is not more than baseline risk of general population. Therefore, evidence-based teratogenic risk counseling may prevent unnecessary pregnancy termination.

OBJECTIVE: To evaluate planned pregnancy rate and associated factors related planned pregnancy. METHODS: We surveyed 1,396 cases from May 2002 to December 2002. The cases were derived from the Maternity school. They filled out questionnaire including planned pregnancy, medico-social-economic status. Then, we assessed the planned pregnancy rate with associated medico-social-economic state, through the prospective study. RESULTS: The planned pregnancy rate is 51.4%. The major factor which affected the planned pregnancy rate is the income of the family. The association with the planned pregnancy rate and the parity, age, and educational attainment of the women are not statistically significant. In unplanned group, exposure to alcohol, X-ray and medication is significantly increased in early pregnancy. CONCLUSION: The planned pregnancy can prevent induced abortion and reduce the birth defects due to early exposure to teratogen. Therefore it is important to make an effort to raise the planned pregnancy rate.

The purpose of this study was to evaluate whether maternal serum (MS) and amniotic fluid (AF) inhibin A levels are elevated in patients who subsequently develop severe preecalmpsia, and to investigate the correlation between MS and AF inhibin A levels in the second trimester. The study included 40 patients who subsequently developed severe preecalmpsia and 80 normal pregnant women. Inhibin A levels in MS and AF were measured with enzyme-linked immunosorbent assay (ELISA). The MS and AF inhibin A levels in patients who developed severe preeclampsia were significantly higher than those in the control group (both for p<0.001). There was a positive correlation between MS and AF inhibin A levels in patients who developed severe preeclampsia (r=0.397, p=0.011), but not in the control group (r=0.185, p=0.126). The best cutoff values of MS and AF inhibin A levels for the prediction of severe preeclampsia were 427 pg/mL and 599 pg/mL, respectively; the estimated ORs that were associated with these cut-off values were 9.95 (95% CI 3.8-25.9, p<0.001) and 6.0 (95% CI 2.3-15.8, p<0.001). An elevated level of inhibin A in MS and AF at the time of second trimester amniocentesis may be a risk factor for the subsequent development of severe preeclampsia.

The purpose of this study is to compare perinatal outcomes of twin pregnancies complicated by gestational diabetes (GDM) with those unaffected by GDM. A total of 1,154 twin pregnancies who delivered at Cheil General Hospital, between January 1998 and December 2002 were recruited to participate in a retrospective analysis. Out of these twin pregnancies, 37 women were had GDM. Four pregnancies exposed to GDM were excluded due to the loss of medical records; therefore 33 twin pregnancies exposed to GDM were enrolled. We matched the GDM pregnancies with pregnancies unaffected by GDM in a 1:2 ratio; therefore there were 33 GDM/66 without GDM who delivered during the study period. Our findings show that there were no significant differences including birth weight, Apgar score, respiratory distress syndrome, meconium aspiration pneumonia, transient tachypnea of new born, hyperbilirubinemia, hypoglycemia, hypocalcemia and congenital anomalies. Therefore, well controlled GDM may not increase perinatal complications in twin pregnancies. Careful pregnancy management and fetal surveillance in twin pregnancies is important to decrease perinatal complications and maintain a sound pregnancy and healthy offspring.
