Clinical study was performed on 42 patients diagnosed as TARVR at the Departmet of pediatrics, Seoul National University Hospital, from January, 1966 to June, 1982. The results are as follows, 1) Of the 25 cases with isolated TAPVR, age distribution was from 10 days to 10 years. Seventeen cases were male and eight cases were female. Of the 24 cases with complicated TAPVR, age distribution was from 2 days to 22 years. Eighteen cases were male and six cases were female. 2) The type of TAPVR was supracardiac in 29 cases (59.1%), cardiac in 10 cases (24.4%), infradiaphragmatic in 3 cases (6.1%) and mixed in 5 cases (10.2%). 3) Birth weights of patients were within normal limits except 1 case. 4) The most freuent complaints at diagnosis were tachypnea and cyanosis. 5) PDA was the most frequently associated intracariac anomaly (54.1%) which was followed by pulmonary stenosis (16.6%), single atrium (16.6%) and single ventricle (16.6%). 6) Of the 25 cases with isolated TAPVR, chest roentgenographic findings were cardiomegaly in 22 cases (88%) and increased pulmonary vascularity in 23 cases (92%). 7) Of the 25 cases with isolated TAPVR, the ECG showed right axis deviation in 22 cases (88%), right atrial enlargement in 13 cases(52%), right ventricular hypertrophy in 24 cases (96%) and combined ventricular hypertrophy in 1 cases (4%). 8) Of the 23 cases with isolated TAPVR, echocardiographic finding showed increased dimension of the right ventricle in all cases. Of the 39 cases with TAPVR, the common venous chamber was visualized posterior to the left atrium in 14 cases(35.8%). 9) Cardiac catheterization was performed in 24 cases with isolated TAPVR. Pulmonary hypertension was observed in 19 cases (79.1%). 10) Fourteen patients with isolated TAPVR were operated. Three patients died.

BACKGROUND: It is difficult to manage the symptoms of neuropathic pain, especially alloynia. The mechanism of the induction and maintenance of mechanical allodynia has been extensively researched for several decades. N-methyl-D-aspartate (NMDA) receptor antagonists are known to reduce mechanical allodynia. Recently, the role of prostaglandins in spinal nociceptive processing has been the focus of attention. Therefore, the present study was designed to investigate the effect of a combination of ketamine, a non-competitive NMDA antagonist, and of ketorolac, non-selective cyclooxygenase (COX) inhibitor on mechanical allodynia. METHODS: Male SD rats were prepared by tightly ligating the left L5 and L6 spinal nerves. All rats developed mechanical allodynia 7 days after surgery. N group (control, n = 6) received 5 ml of 0.9% normal saline intraperitoneally. K group (n = 6) received ketamine 1 mg/kg. T group received ketorolac 30 mg/kg, and KT group received ketamine 1 mg/kg and ketorolac 30 mg/kg simultaneously. Paw withdrawal thresholds to von Frey hairs were measured before and at 15 min, 30 min, 60 min and 120 min after drug administration. RESULTS: Normal saline and ketamine 1 mg/kg did not increase the paw withdrawal threshold from baseline. Ketorolac 30 mg/kg increased the paw withdrawal threshold only at 120 min after intraperitoneal injection. However, the co-administration of ketamine 1 mg/kg and ketorolac 30 mg/kg increased the paw withdrawal threshold significantly from baseline for 120 min. CONCLUSIONS: Intraperitoneal injection of ketamine and ketorolac attenuated the mechanical allodynia developed by spinal nerve ligation. Therefore, we suggest that combination of ketamine and ketorolac might be useful for the management of neuropathic pain.

Shwachman-Diamond syndrome (SDS) is a rare genetic disorder of unknown pathogenesis involving exocrine pancreatic insufficiency and hematological and skeletal abnormalities. About 25% of patients develop hematopoietic malignancies. We report on a case of acute myeloid leukemia (M2) in a 21-year-old woman affected by SDS. She was treated with conventional chemotherapy (idarubicin plus cytarabine) and reached complete remission of leukemia. After induction chemotherapy, she underwent allogeneic bone marrow transplantation (BMT). The BMT preparative regimen consisted of total body irradation (TBI) followed by cyclophosphamide. Cyclosporin A and short term methotrexate were used for graft-versus-host disease prophylaxis. After a follow-up of 12 months, she is alive leukemia free off any immunosuppressive agent. Although experience in this field is scarce, we speculate that bone marrow failure in SDS is an indication for BMT which is the only curative trentment option.

OBJECTIVE: Preterm labor and delivery is probably the largest problem in modern perinatology. The early diagnosis of preterm labor is crucial for prevention of preterm birth. To predict the onset of preterm labor, we examined the diagnostic performance of serial cervical assessment by transvaginal sonography. METHODS: In this prospective study, we performed transvaginal sonography at approximately 30 and 34 weeks of gestation in women with singleton pregnancies. Cervical parameters evaluated included endocervical length, the presence of funneling, funnel length and funnel width. We then assessed the relation between cervical parameters and the risk of spontaneous preterm labor. RESULTS: We examined 258 women at approximately 30 weeks of gestation and 247 of these women again at approximately 34 weeks. Spontaneous preterm labor occurred in 9 of women examined at 30 weeks(Group 1) and in 13 at 34 weeks(Group 2). The endocervical length was normally distributed at 30 and 34 weeks(mean +/-SD, 38.26+/-6.82mm and 35.63+/-7.35mm, respectively). The endocervical length decreased significantly from 30weeks to 34 weeks(p=0.0001). Both groups showed significantly shorter endocervical length(p <0.05) and groupl more presence of funneling than group of term pregnancy(p<0.05). Receiver-operator characteristic curve and multiple logistic regression analyses indicated that endocervical length <-30mm at 30 weeks and <-25mm at 34 showed highest diagnostic index in predicting the onset of preterm labor(p=0.0001). Conclusions: Serial transvaginal ultrasound assessment of endocervical length during early third trimester is a useful predictor of preterm labor and delivery in low-risk patients.

BACKGROUND: Chlamydia trachomatis is most common sexually transmitted pathogen in the world, and a common cause of urethritis and cervicitis. Also it is common cause of preterm premature rupture of membranes and premature labor in pregnant women, and pneumonitis and conjunctivitis in neonate. A rapid and sensitive polymerase chain reaction(PCR)-based assay for detection of C. trachomatis is recently introduced. OBJECTIVES: We studied to determine whether a PCR assay is useful to detect Chlamydial infection in pregnant women. We also studied to compare its prevalence rate according to maternal age, trimester and parity, respectively. Study Design: Specimens were collected from 149 pregnant women by transcervical swab or endocervical lavage. If a specific band was detected in PCR assay, we considered as Chlamydial infection. RESULTS: In general, the positive bands were detected in the 45 of 149 pregnant women(30.2%). The positive bands were detected the 6 of 55(10.9%), 16 of 49(32.7%), and 23 of 45(51.1%) pregnant women in each trimester, respectively. Therefore, there was significantly increased according to the gestational age(p<0.05). However, there were not significantly different according to maternal age and parity(p> 0.05). CONCLUSION: We concluded that the PCR assay is a fast and useful test for the detection of C. trachomatis in transcevical cells from the pregnant women. This study suggested that Chlamydial infection seems to be increased according to the gestational age.

OBJECTIVES: The purpose of this study is to analyze the previously unreported effect of fetal sex on the fetal heart rate and to measure its magnitude in relation to the effects of other independent clinical variables. METHODS: Three hundred and seventeen pregnant women who were able to provide electronic fetal heart rate monitoring were evaluated. On the basis of fetal sex after birth, 167 pregnant women who delivered male neonate were for males group and 146 examples who delivered female neonate were for female group. We analyzed fetal heart rate data using the Catholic Computer Assisted Obstetric Diagnosis System(CCAOD). RESULTS: Female fetuses had significantly faster basal heart rate(140.51+/-12.43bpm) than male fetuses(137.64+/-13.68 bpm).(P=0.007) Percent acceleration time(PAT) increased significantly for males(6.10+/-4.00bpm), comparing to females(4.90+/-3.34bpm).(P=0.001) Also percent deceleration time(PDT) was significantly higher in male fetuses(7.50+/-8.70bpm) than female fetuses(6.18+/-7.70bpm).(P=0.039) But there was no differences in standard deviation(SD)(8.84+/-10.11bpm, 8.11+/-3.56bpm), long term variation(LTV)(80.38+/-62.79msec, 73.65+/-54.60msec), and short term variation(STV)(14.06+/-9.79msec, 13.33+/-12.32msec) between male and female fetuses. CONCLUSION: The fetal heart rate of female fetuses differ from that of male fetuses. Computerized linear analysis and nonlinear analysis of antepartum fetal heart rate will need to take into account the multiple factors that influence the fetal heart rate to identify precisely which pattern predict clinical outcome.

BACKGROUND: Under normal conditions, cerebral blood flow is regulated as cerebral perfusion pressure changes (autoregulation). Inflammatory conditions like bacterial meiningitis result in a loss of cerebral autoregulation several hours after exposure to bacterial endotoxin. Endotoxin appears to produce effects via the production of reactive oxygen species, such as the superoxide anion. METHODS: Cerebral blood flow (CBF) was measured by hydrogen clearance in anesthetized rats 30 minutes after intravenous endotoxin 5 mg/kg or normal saline (control). Mean arterial pressure was reduced from 100 mmHg to 80 mmHg and 60 mmHg by hemorragic hypotension, and cerebral blood flow was measured at each pressure. RESULTS: In the control group, CBF did not change when arterial pressure was reduced to 80 mmHg (113.9 ml vs 111.9 ml), but declined significantly at 60 mmHg (113.9 ml vs 88.4 ml). In the group treated with endotoxin, both a reduction of mean arterial pressure to 80 mmHg (129.8 ml vs 101.8 ml) and 60 mmHg (129.8 ml vs 78.4 ml) caused a significant reduction in CBF, indicating that autoregualtion had been abolished. CONCLUSIONS: The results of this study indicate that within minutes of endotoxin exposure, CBF markedly increased, and that the autoregualtion of CBF was inhibited.

OBJECTIVE: The study was to evaluate the biological significance of Ki-67 expression in common epithelial ovarian carcinomas. We investigated the correlation between Ki-67 expression and clinicopathological parameters. METHODS: One hundred patients with epithelial ovarian carcinomas stage I-IV treated at Department of Obstertrics and Gynecology, Korea University Hospital from January 1994 to December 2004 were used as study group. We determined expression of Ki-67 by immunohistochemistry using MIB-1 monoclonal antibody reactivity. RESULTS: Ki-67 overexpression was higher in high stage (III-IV) than low stage (I-II) (P<0.013). Ki-67 overexpression was higher in serous cystadenocarcinoma (76.3%) than mucinous cystadenocarcinoma (53.6%), endometrioid carcinoma (54.5%) and clear cell carcinoma (58.3%) but it was not statistically significant (P<0.191). Ki-67 expression was higher in high grade but it was not statistically significant (P<0.096). Ki-67 overexpression was not correlated with serum CA-125 level (P<0.172). Overall survival revealed significant survival difference between patients whose tumor showed Ki-67 overexpressions compared with remaining patients. CONCLUSIONS: Ki-67 overexpressions was a poor prognostic indicator in epithelial ovarian carcinomas.
