OBJECTIVE: To evaluate whether lipopolysaccharide (LPS) modulates the expression of cyclooxy- genase-2 (COX-2) and also whether COX-2 is involved in the LPS induced matrix metalloproteinase-2 (MMP-2) and MMP-9 activation in human trophoblastic (TL) cell line. METHODS: We used the TL (trophoblast-like) cells and evaluated the effect of LPS on expression of COX-2 mRNA and protein and on activities of MMP-2 and MMP-9. Also, we pretreated cell line with LPS and NS398, a COX-2 inhibitor, and compared MMPs activities with LPS only group. In the present study, COX-2 was analyzed by RT-PCR and western blot analysis and gelatin zymography was done for the evaluation of gelatinase activities of MMP-2 and MMP-9. RESULTS: The mRNA and protein expressions of COX-2 were increased by LPS in time- and dose-dependant fashions. COX-2 mRNA expression began to rise from 1 hour of LPS treatment and was increased steadily thereafter. COX-2 protein expression was detected from 1 hour of LPS treatment, but maximally increased by the 3 hours of treatment. LPS also increased MMP-2 and MMP-9 activities in time and dose dependant fashions. Especially, active form of MMP-9 was observed in the high concentration of LPS (>50 microgram/ml). When adding COX-2 inhibitor (NS398) to LPS pretreated cell line, the MMPs activities increased in two or three fold compared to LPS only group. CONCLUSION: Our results suggested that LPS induces expression COX-2 and up-regulates activities of MMP-2 and MMP-9 in trophoblastic cell, but COX-2 although involved in LPS mediated MMP-2 and MMP-9 activation, may act through a different pathway than the commonly known prostaglandin metabolites mediated one.

OBJECTIVE: To study the clinical characteristics of ovarian tumors accompanied with pregnancy. METHODS: A review was performed of 310 cases of ovarian tumors surgically resected during pregnancy from January 1990 to December 2001. RESULTS: The incidence of ovarian tumor in pregnancy was one in 181.5 deliveries and that of malignant neoplastic tumor was one in 6,251 deliveries. Among 310 cases undergoing ovarian surgery, tumor-like lesions were 110 cases (35.5%), benign tumors were 191 cases (61.6%), and malignant tumors were 9 cases (0.3%), respectively. One hundred and twenty cases of dermoid cyst (38.7%) occured most frequently, followed by 47 cases of corpus luteal cyst (15.2%), and 40 cases of simple cyst (12.9%). One hundred and ninety nine cases (64.2%) of ovarian tumors were greater than 6 cm in diameter and 189 cases (61%) were preoperatively diagnosed in 1st trimester, and 62 cases (20%) were detected incidentally during cesarean section. In complicated cases, the torsion of ovarian tumor was found in 48 cases (71.6%), the cases of rupture were 16 (23.9%), and misdiagnosed cases as appendicitis were 3 (4.5%). According to outcome of pregnancy, abortions were 19 cases (6.1%), vaginal deliveries were 43 cases (13.9%), and cesarean sections were 169 cases (53.5%). CONCLUSION: Although the incidence of malignant ovarian tumor is low, the overall incidence of ovarian tumor in pregnance is increasing. Because ovarian tumors complicating pregnancy are often entirely unsuspected, careful examination of all pregnant women in early pregnancy must be considered.

OBJECTIVE: Pregnant women have various fears and expectations regarding the impending birth. Fears can influence the course of the delivery and post-partum period. The DFS (Delivery Fear Scale) measures fear during labor and delivery in an effortless and fast away. The aim of this study were to compare DFS score and parity, maternal age, history of abortion, baby gender during an early stage of active labor (cervix dilatation 3-5 centimeters). METHODS: Review of the medical records from the department of obstetrics and gynecology from January 2004 to December confirmed 151 patients with the diagnosis of singleton pregnancy without medical or obstetrical complications, being in 37-42 weeks. 86 primiparous and 65 multiparous women answered the Delivery Fear Scale (DFS) once during active labor. Mann-Whitney test was applied to test possible differences between DFS and variable factors. Difference were considered to be statistically significant at p<0.05. RESULTS: Primiparous women had higher scores on the DFS than multiparous women during active labor. But DFS was not associated with maternal age, history of abortion, baby gender during an early stage of active labor. CONCLUSION: Women's psychological experiences during the actual process of labor and delivery are essential part of obstetrical care. Nevertheless, studies examining psychological variables concerning childbirth, are mostly performed before or after labor. The understanding of a fear during labor is to support the woman in labor in a way that decrease fear and the development of the DFS may facilitate future research in the field.

Intrauterine device is one of the most used contraception in the world. One of the major complications of intrauterine contraception is perforation through the uterine wall into the pelvic or abdominal cavity. The currently accepted treatment of choice for displaced IUD is its removal of surgical laparoscopy or laparotomy. We report on three cases with misplaced IUD in pelvic or abdominal cavity, followed by a review of the literature.

Ovarian cysts are common incidental findings in term infants and, if unusually large, may result in dystocia, torsion, or rupture. We report the case in which serial sonographic examination revealed changing pattern of cystic ovarian mass from hypoechogenic to well defined multiseptated echogenic during pregnancy. Postnatal T2-weighted MR images revealed a multilocular with high signal density. After delivery a laparotomy was performed, and a twisted ovary measuring 6.7x5x4.5 cm was removed. Ovarian torsion was left-sided and had been almost autoamputated. The resected specimens were nontense, thin walled cysts, filled with hemorrhage like fluid. Histological examination demonstrated the presence of lymphangioma with widespread hemorrhage and necrosis. The neonate did well after the procedure.

Placenta percreta is a extremely rare but it is accompanied by serious complication of pregnancy and its prediction is very difficult. Since spontaneous uterine rupture during the first trimester is an obstetric emergency, though it is rare, it is crucial that proper management should be taken promptly in order to decrease maternal and fetal morbidity and motality. We present a case of the spontaneous rupture of the uterus in the 14th week of pregnancy with a brief review of the literatures.

OBJECTIVE: To determine obstetric outcome in infants > or =4,500 g according to delivery mode. METHODS: Records of 271 mothers and infants weighing > or =4,500 g over a 11-year period (1993~2003) were retrospectively reviewed. Maternal and perinatal outcomes were compared in relation to delivery mode. RESULTS: The frequency of macrosomia ranged 0.38% in 4,500 g or more. Vaginal delivery was achievable in 78/271 (28.8%) of women allowed to labor, of which 71.2% were operative. In macrosomia frequency correlations to parity showed 33.9% (92 cases) in primiparous women, 66.9% (179 cases) in multiparous women. According to the type of delivery, cesarean section has proven to be the most popular mode. The cesarean section group had a higher incidence of maternal BMI (> 25 kg/m2). The frequency of diabetes, hypertension, low Apgar score at 5 and 10 minutes was similar in both groups. CONCLUSION: It would be appropriate to have definite diagnostic schemes and adequate choice of delivery method for macrosomia. Maternal height, weight, BMI (body mass index) may associated with fetal body weight and delivery mode.

OBJECTIVE: To assess the clinical characteristics, laboratory findings, the maternal and neonatal complications between HELLP syndrome and severe preeclampsia. METHODS: We reviewed the material and neonatal charts of 34 pregnancies complicated by HELLP syndrome and 40 pregnancies complicated by severe preeclampsia managed at our hospital between January, 2001 and December, 2005. We compared the clinical characteristics, laboratory findings, the maternal and neonatal complications between two groups. Results were compared by student T test, chi-square test. RESULTS: Our study showed that in HELLP syndrome patients had the less gestational age at admission, gestational age at delivery, the lower platelet counts, the higher AST, ALT, LDH, and the longer hospitalization period than in severe preeclampsia. Steroid (dexamethasone) use, cesarean delivery rate and MgSO4 use were more frequent in HELLP syndrome than severe preeclampsia. Neonatal birth weight was lower with HELLP syndrome. There was no significant difference in maternal and neonatal complications. CONCLUSION: HELLP syndrome need to be recognized a unique form of severe preeclampsia. It was associated with serious maternal and fetal mortality, the appropriate management would be done by early diagnosis using laboratory tests.

OBJECTIVE: To study intrauterine or extrauterine misplacement of intrauterine devices in respect to their usage in diagnosis and therapy via retrospective analysis. METHODS: Data from 1993 to 2000 on a total of 32 patients from seven Catholic University branch hospitals who had been admitted to treat IUDs which had misplaced to intrauterine or extrauterine locations were analyzed for usage in a retrospective study. RESULTS: The data for intrauterine and extrauterine misplacement revealed no significant difference between from the statistical average in relation to age, parity and duration of insertion. In terms of removal method, all 15 patients with extrauterine misplacement underwent surgical extraction by open or laparascopic method under general anesthesia, but those patients with intrauterine misplacement had their device removed after cervical dilatation with a laminaria using local anesthesia. Concerning diagnosis, 81.2% of extrauterine misplacement were diagnosed using x-ray while 58% of intrauterine misplacement were diagnosed using vaginal US. The result of the Fisher's exact test showed a significant difference (p=0.043) in the rate of diagnosis for intrauterine and extrauterine misplacement of IUDs. Also, the results of multi-variable analysis performed for logistical regression analysis showed that intrauterine misplacement occurred 1.23 times more frequently than extrauterine misplacement. CONCLUSION: Further studies are required on a broader patient population, on more types of IUDs and with time variables taken into account. Despite more research, prevention of complications such as misplacement remains the most appealing situation, being influenced by such factors as technical skill of the physician inserting the IUD, appropriate duration of insertion and proper patient education.
