Glycogen synthase kinase 3β and cyclin D1 expression in cervical carcinogenesis

OBJECTIVE: Glycogen synthase kinase 3β (GSK3β) is a pluripotent protein kinase involved in the development of cancers through regulation of numerous oncogenic molecules. Cyclin D1, an important regulator of G1 to S phase transition in various cells, is one of target proteins that GSK3β regulate. Our objective was to assess the expression of GSK3β and cyclin D1 in cervical neoplasm of different histologic grades and to identify their correlation in cervical carcinogenesis. METHODS: Immunohistochemical analysis of GSK3β and cyclin D1 was performed in a total of 137 patients with 12 normal, 62 cervical intraepithelial neoplasia (CIN) (31 CIN1 and 31 CIN3) and 63 invasive cancers including 56 squamous cell carcinomas and 7 adenocarcinomas. RESULTS: The expression of GSK3β increased in parallel with the lesion grade, while that of cyclin D1 decreased with severity of the lesion (P<0.001). There was a significant inverse correlation between GSK3β and cyclin D1 expression in overall cervical neoplasia (Φ=-0.413, P<0.001). GSK3β expression was higher in squamous cell carcinoma than in adenocarcinoma (P=0.049). CONCLUSION: These results suggest that the expressional increase in GSK3β plays a role in cervical carcinogenesis and has inverse correlation with cyclin D1 expression in this process. In addition, GSK3β expression appears to be associated with the histologic type of cervical cancer, especially squamous cell carcinoma.

Who is more appropriate to do metabolic control of pregnancy complicated by diabetes?: Comparison of internist and obstetrician / 대한산부인과학회지

OBJECTIVE: To compared obstetric outcomes of pregnancies complicated by diabetes according to the managing department and to consider role of obstetrician and endocrinologist METHODS: A retrospective analysis of 72 pregnant women managed for diabetes during March 2004 to December 2006 was performed. Eighteen women had been managed by obstetricians (Group I) while 54 women had been managed by endocrinologists of internal medicine (Group II) during their pregnancies at Eulji Hospital. None of these patients had multiple pregnancies, abnormal karyotype, or other medical disorders other than diabetes. Pregnancy outcomes were compared between two groups. RESULTS: No difference was found with regard to the age, parity, BMI (body mass index), weight gain during the pregnancy, and the gestational weeks of delivery. There was also no difference in the blood glucose levels after 100 gm OGTT (oral glucose tolerance test) and HbA1C levels in two groups. The neonatal birth weight of group I (2.89+/-0.21 kg) was significantly lower than that of group II (3.38+/-0.08 kg, P=0.040). The 1 min APGAR score, which was corrected by weight through ANCOVA test, was also significantly lower in group I (7.11+/-0.51 vs 8.11+/-0.19, P=0.028). But There was no difference in 5 min APGAR score. The incidence of birth weight over 3.8kg was significantly higher in group II [37/54 (68.5%) vs 1/17 (5.6%), P=0.030]. Neonatal hypoglycemia was also higher in group II (37.0% vs 11.1%, P=0.043). Other neonatal and maternal complications associated with diabetes were not significantly different between two groups. CONCLUSIONS: In medical point of view, obstetrician can effectively manage diabetes during pregnancy as good as internist. Besides, the management by obstetricians may be more economic, less annoying, and can induce more compliance and motivation of the patients.

Endocrine response to step-up microdose GnRH agonist / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to evaluate the endocrine response to step-up microdose GnRH agonist. METHODS: Administration of triptorelin acetate was initiated from 2 mg and gradually increased to 50 mg during 6-day period to five normal menstruating women. Serum FSH, LH, and estradiol levels were serially measured for 6 days. The same set of experiment was duplicated after taking oral contraceptive for 3 weeks. Serum testosterone and progesterone levels were measured on day 1 and day 5 of experiment. RESULTS: The flare of gonadotropin continued for 6 days. When subjects were pretreated with oral contraceptive, serum FSH levels 4 hrs after GnRH agonist injection were 17.35+/-7.88 mIU/mL, 11.26+/-4.81 mIU/mL, and 9.60+/-4.08 mIU/mL for day 1, 2, and 3 respectively. The FSH levels were not statistically different when pretreatment with oral contraceptive was not applied. The level of serum LH was significantly lower in the cycle, which was pretreated by oral contraceptive (32.13+/-9.61 mIU/mL vs. 14.12+/-5.63 mIU/mL for day 1, 28.95+/-3.09 mIU/mL vs. 15.76+/-9.92 mIU/mL for day 2, and 24.45+/-2.52 mIU/mL vs. 16.86+/-8.56 mIU/mL for day 3). The sign of corpus luteum rescue was found in 2 out of 5 subjects only in non-treated cycle. CONCLUSION: Step-up microdose GnRH agonist protocol could induce persistent gonadotropin flare for 6 days and this regimen could be applied in controlled ovarian hyperstimulation especially for poor responders. The pretreatment with oral contraceptive is necessary to prevent supraphysiologic LH elevation and corpus luteum rescue.

Clinical characteristics and pregnancy outcomes of hyperemesis gravidarum / 대한산부인과학회지

OBJECTIVE: It is controversial that hyperemesis gravidarum has adverse effect on pregnancy. The purpose of this study is to evaluate clinical characteristics and pregnancy outcomes in women with hyperemesis gravidarum. METHODS: We identified 52 women who was treated as inpatients for hyperemesis gravidarum and had delivered babies between Jan. 2001 and Oct. 2004. The control group was 123 women who had not suffered from hyperemesis gravidarum. We performed a retrospective analysis of obstetric and pediatric medical records. We analyzed the data using student's t-test and Chi-square test and p-value<0.05 was considered as statistically significant. RESULTS: The average height (162.5+/-0.6 vs. 160.6+/-0.4 cm, Mean+/-SE) was significantly higher in hyperemesis group. The average pre-pregnancy BMI (20.2+/-0.3 vs. 21.0+/-0.2 kg/m2) and maternal age (29.8+/-0.5 vs. 31.2+/-0.3 years) were significantly lower in hyperemesis group. The average weight loss was 2.6 kg and the average hospital stay was 5.4 days. The average concentration of serum electrolytes were within normal limits. The hematocrit (35.4+/-0.4 vs. 34.3+/-0.2%) and unconjugated estriol (1.336+/-0.055 vs. 1.126+/-0.034 MoM) were significantly higher in hyperemesis group. Vaginal bleeding during the first trimester was more common in hyperemesis group (16.4 vs. 4.7%). Pregnancy outcomes between hyperemesis and control group were similar in average gestational age, average birth weight, average Apgar scores, sex ratio, congenital malformation and neonatal morbidity. CONCLUSION: Pregnant women with hyperemesis had significant differences in some demographic characteristics, hematocrit, unconjugated estriol and vaginal bleeding during the first trimester, but had similar pregnancy outcomes.

The differences of mid-trimester triple marker levels according to the occurrence time and severity of preeclampsia / 대한산부인과학회지

OBJECTIVE: To evaluate the differences of mid-trimester triple marker levels in patients with mild versus severe and early versus late onset preeclampsia. METHODS: From January 2000 to December 2004, a retrospective study of 65 women with preeclampsia for whom mid-trimester triple test data were available was made. None of these patients had diabetes, other medical disorders, multiple pregnancy, abnormal karyotype and malformations. Preeclampsia patients were grouped to "early onset" [<32 weeks of gestation (wks), n=17] and "late onset" (n=48), and also "mild" (who had delivered with no symptoms and lab findings of severe preeclampsia at term spontaneous labor or elective cesarean delivery, n=31) and "severe" (n=34). The levels of mid-trimester maternal serum alpha-fetoprotein (MSAFP), human chorionic gonadotropin (hCG) and unconjugate estriol (MSuE3) in patients with early and late onset, mild and severe were compared. RESULTS: The each groups of comparison did not differ significantly with regard to age, weight, parity. The mean MSuE3 [0.92+/-0.09 (MoM+/-SE)] in patients with early onset was significantly lower than in patients with late onset preeclampsia (1.24 MoM, SE 0.07). In the comparison according to severity, the mean MSuE3 was significantly lower (0.98 MoM, SE 0.06 vs 1.28 MoM, SE 0.10, p=0.016) and the mean hCG was significantly higher (1.46 MoM, SE 0.12 vs 1.12 MoM, SE 0.07, p=0.015) in patients with severe preeclampsia than in those had mild preeclampsia symptoms at term delivery. CONCLUSION: Lower levels of mid-trimester MSuE3 and higher levels of hCG were associated with the severe preeclampsia rather than mild. Especially, lower levels of mid-trimester MSuE3 was also associated with early onset preeclampsia.

The role of angiotensin II to regulation of steroidogenic pathway in human ovarian follicle / 대한산부인과학회지

OBJECTIVE: The exact mechanism of angiotensin II to steroidogenesis is still speculative in spite of many researches especially in human and these were performed indirectly with serum or follicular fluid. Under the hypothesis that ovarian RAS increases androgen, decreases progesterone synthesis in normal human ovary, we investigated the exact action of angiotnesin II on human ovary. METHODS: After appliance of angiotensin II and saralasin to the normal human ovarian follicles, we measured sex steroids like progesterone, testosterone, DHEA and enzymes like HSD3beta2, CYP 17 to see the action of angiotensin II and its antagonist, saralasin. The results were analyzed by ANOVA test. RESULTS: Angiotensin II increased androgen synthesis but did not affect progesterone synthesis. There were no difference of HSD 3beta2 mRNA expression in angiotensin II and saralasin group compared with control group. The expression of CYP17 mRNA was increased by angiotensin II but did not reach statistically significant level. CONCLUSION: Angiotensin II could increase androgen production probably via overexpression of CYP17, but had no efffect on progesterone production.

A comparison of the effect of Anastrozole and Clomiphene citrate in anovulatory patients / 대한산부인과학회지

OBJECTIVE: To compare the clinical effectiveness of Anastrozole in ovulation induction with that of clomiphene citrate. METHODS: Sixty anovulatory women were randomly divided into 4 groups (1 mg, 2 mg and 4 mg of Anastrozole groups and Clomiphene citrate group). The ovulation induction was tried with 3 dosages of Anastrozole or 100 mg of Clomiphene citrate for 5 days. The serum level of estradiol, testosterone, FSH and LH were serially monitored (on 3rd, 5th and 8th days of treatment). Serum estradiol level at the time of hCG injection was also measured. Ovulation rate, number of dominant follicles, endometrial thickness, and pregnancy rate were measured and compared across the study groups. RESULTS: There was no statistically significant difference in estradiol, testosterone, or LH level between women treated with Anastrozole and Clomiphene citrate. In patients treated with 4 mg of Anastrozole, serum FSH level was higher than that of the women treated with Clomiphene citrate (P<0.05). Endometrial thickness was greater in patients treated with Anastrozole than women treated with Clomiphene citrate (P<0.05). Number of dominant follicles in patients treated with Clomiphene (1.56) was slightly greater than in women treated with Anastrozole (1.0-1.1), but there was no statistically significant difference. CONCLUSION: Anastrozole had similar clinical effectiveness in ovulation induction when compared to Clomiphene citrate. At 1 mg or 2 mg of Anastrozole, ovulatory rate remained below the effectiveness of Clomiphene citrate, therefore considering the expensive cost of Anastrozole, it should not be considered as first-line medication for ovulation induction but reserved for those who have certain conditions such as thin endometrium and polycystic ovarian syndrome.

Complete androgen insensitivity syndrome due to androgen receptor gene mutation in the amino acid position 607 which bilateral testes situated in the normal ovary sites / 대한산부인과학회지

Androgen insensitivity syndrome (AIS) is a disorder of male sexual differentiation caused by mutations within the androgen receptor gene, represents a variety of phenotypes from females with 46,XY karyotype over individuals with ambiguous genitalia to infertile males. Single base mutations resulting in amino acid substitution represent the most common mutations of the androgen receptor (AR) gene and are associated with complete AIS. The location of the gonads can be variable including, the intra-abdominal cavity, the labioscrotal folds, and the inguinal regions. Testicular descent is a two-stage process comprising transabdominal and transinguinal phases. The first phase is not controlled by androgen and may be regulated by mullerian inhibiting substance, by contrast the second phase is androgen dependent. Recently we have identified a point mutation CGA to TGA at position 607 of exon 3 in complete AIS patient, so we report it with brief review of literatures.

A Case of Miliary Tuberculosis During Pregnancy / 대한주산의학회잡지

Although miliary tuberculosis is uncommon during pregnancy. it is often associated with a maternal history of intravenous drug abuse, malignancy, alcoholism, or human immunodeficiency virus infection, and it is difficult to diagnose when associated with pregnancy. There is no solid evidence that pregnancy has an adverse effect on tuberculosis, thus routine therapeutic abortion is not indicated. If the early diagnosis and promptly adequate chemotherapy was done, the outcome of pregnancy in a women with miliary tuberculosis is likely to be good. Recently we have experienced a case of miliary tuberculosis at 20 weeks gestation without any risk factors of tuberculosis. So we report this case with a brief review of literature.

Comparative Study of Maternal and Perinatal Complications in Overt and Gestational Diabetes / 대한주산의학회잡지

OBJECTIVES: The purpose of this study is to evaluate and compare the maternal and neonatal complications of the overt diabetes with that of gestational diabetes. METHOD : The medical records of 65 pregnant patients complicated by diabetes mellitus at Eulji medical center from January, 2001 to December, 2002 were reviewed retrospectively. Thirteen patients of them were diagnosed as a overt diabetes and the others were diagnosed as a gestational diabetes. RESULTS: Maternal complications were that preeclampsia in 15.4% and preterm labor in 15.4% in overt diabetes patients and preeclampsia in 9.6%, fourth degree laceration in 1.9%, preterm labor in 3.8%, placenta abruption in 1.9%, cardiomyopathy in 1.9% and polyhydroamnios in 1.9% in gestational diabetes patients. Neonatal complications were that hypoglycemia in 38.5% and respiratory distress syndrome in 15.4% in overt diabetes patients and hypoglycemia in 25%, hyperbilirubinemia in 9.6% and shoulder dystocia in 1.9% in gestational diabetes patients. There were no statistic differences in maternal and neonatal complications in two groups when management had done. And in gestational diabetes group, maternal and neonatal complications were significantly higher in no management group than management group regardless of management types. CONCLUSION: If early detection and management were done in overt and gestational diabetes, there were no difference in maternal and neonatal complications. Regardless of types of diabetes, early detection and management were important.

Clinical Consideration on the Method of Hysterectomy / 대한산부인과학회잡지

OBJECTIVE: The most common operation in gynecology is hysterectomy. To compare the indications, patient characteristics and clinical outcome, complication between total abdominal hysterectomy (TAH) and vaginal total hysterectomy (TVH), laparoscopically assisted vaginal hysterectomy (LAVH). METHODS: This study was designed to analyze 147 patients of TAH (Group I) from January 2003 to September 2003, 48 patients of TVH (Group II), 108 patients of LAVH (Group III) at Eulji medical center of obstetrics and gynecology from January 2002 to September 2003. We analyzed the result with patient characteristics, parity, medical disease, history of previous operation, indication of hysterectomy, uterine weight, concurrent surgical procedure, operation time, bleeding amount, complication and length of hospital stay. Uterine prolapse was excluded in the analysis of this study. RESULTS: Patient characteristics, parity, medical disease were no differences. Number of previous operation were 63 cases (42.9%) in TAH group, 10 cases (20.8%) in TVH group, 43 cases (39.8%) in LAVH group, and the most common of operation was tubal ligation in three gropups. Most common indication of hysterectomy was uterine leiomyoma. The mean uterine weight was 374.31 +/- 250.26 gm in TAH group, 187.70 +/- 109.62 gm in TVH group and 203.26 +/- 94.92 gm in LAVH group. The mean operation time was 89.61 +/- 25.24 min in TAH group, 73.39 +/- 21.80 min in TVH group and 96.18 +/- 27.98 min in LAVH group. Postoperative complication was observed 60 cases (40.8%) in TAH group, 8 cases (16.7%) in TVH group, 19 cases (17.6%) in LAVH group. Most common complication was bleeding and required transfusion (TAH 32 cases (21.8%), TVH 3 cases (6.3%), LAVH 10 cases (9.3%)). CONCLUSION: LAVH and TVH present superior result in terms of complication when compared with TAH. LAVH and TVH have advantage of lower morbidity, less pain, shorter hospital stay and convalescence. LAVH should be considered when the vaginal approach is unfeasible, showing clear advantages over abdominal hysterectomy.

Two Cases of Mullerian Agenesis Undergone Vaginal Reconstruction by McIndoe Technique / 대한산부인과학회잡지

Vaginal agenesis is uncommon gynecologic condition, and the most common etiology is Mullerian agenesis also called Mayer-Rokitansky-Kster-Hauser (MRKH) syndrome. In such patients, the evaluation for associated malformations as well as careful non-surgical and surgical approach are essential. The neovaginoplasty is an important issue for these patients from a functional and a psychological standpoint. We describe two patients with Mullerian agenesis, who have undergone vaginal reconstruction by McIndoe technique.

Spontaneous Hepatic Rupture Following an Uncomplicated Pregnancy and Delivery / 한국간담췌외과학회지

Spontaneous rupture of the liver in pregnancy is extremely uncommon. The most of cases have occurred in pregnancy with preeclampsia/eclampsia. We report one case of spontaneous capsular rupture following an uncomplicated pregnancy. A 33 year old woman was admitted at 38 weeks of gestation to the Obstetrics department. On admission her pulse and blood pressure were normal and there was no proteinuria. On the next day, a cesarean section was performed with delivery of a male infant (3.8 kg). but persistent uterine bleeding was developed due to uterine atony. and then subtotal hysterectomy was performed. Postoperatively she was remained unstable requiring further transfusion of blood and fresh frozen plasma. She was reoperated for controling persistent bleeding and evacuation hematoma of previous hysterectomy site. Postoperatively she was stable during 48 hours. However she again became hypotensive and on examination was noted intra-abdominal fresh bleeding. Laboratory evaluation demonstrated a high level of LFT. Contrast enhanced CT revealed subcapsular hematoma rupture and active bleeding of liver. We tried to embolized the terminal hepatic arterial branch for controling the ruptured subcapsular hematoma. and then she was stable but after 5th days, liver necrosis was developed and progressed to abscess. Despite radiologic drainage, necrotic abscess was remained persistently. She was managed with open drainage and debridement of necrotic liver. After 2 weeks, she was discharged without any morbidity.

A Case Diagnosed to Cushing's Syndrome Caused by Adrenal Cortical Adenoma during Pregnancy after Ovulation Induction / 대한산부인과학회잡지

This woman was a secondary infertile patient with amenorrhea, hirsutism, and hyperprolactinemia due to excessive secretion of androgen. We had an impression that her disease was polycystic ovary syndrome, and she became pregnant after ovulation induction. Complications arised, such as hypertension, diabetes and pulmonary edema at 23rd week of pregnancy and physical findings of Cushing's syndrome were observed. Cushing's syndrome caused by adrenal cortical adenoma was diagnosed through endocrine and radiologic examination. We let her keep pregnancy through adjusting hypercorticolism with metyrapone to restrain abnormal steroidogenesis during pregnancy. After delivery, we carried out adrenalectomy through laparoscopic surgery and then can't find out any problem to be appeared to the mother and her neonate. We report this case with brief discussion.

Efficacy of estradiol supplement therapy for patients with thin endometrium in intrauterine insemination cycles / 대한산부인과학회잡지

OBJECTIVE: To evaluate the endometrial response and to compare the pregnancy outcome of estradiol supplement in patients with abnormally thin endometrium who are undergoing IUI. METHODS : From November 1st, 1998 to February 28th, 2001, 914 IUI cycles were studied and which were divided into several groups. In preparatory cycle, all of the patients were prepared with conjugated estrogen. The patients were divided into several groups according to the endometrial thickness (ET). Control I (n=734) was normal control group (ET>or=7 mm). Control II (n=67) was control group with abnormally thin endometrium (ETintrauterine insemination7 mm) without estradiol supplement. Group I (n=65) and group II (n=48) had thin endometrial thickness. However, in preparatory cycle, the endometrial thickness was more than 7 mm in group I and was less than 7 mm in group II. Uterine preparation consisted of 6-8 mg of estradiol valerate. The number of natural cycle was 234 and the hyperstimulation protocol used were clomiphene (n=250), clomiphene/ hMG (n=214), hMG (n=216). RESULTS: The average pregnancy rate in group I was 15.4%. There was no significant difference between control I (21.1%) and group I. The pregnancy rate in control II and group II was significantly decreased (3.0 vs. 6.3%) compared with control I and group I. In control I and group I, average endometrial thickness and pregnancy rate were decreased when clomiphene was used compared with hMG alone. (endometrial thickness control I 8.4 +/- 0.6 vs. 10.0 +/- 0.7 mm, group I 6.9 +/- 0.8 vs. 7.9 +/- 0.7 mm, pregnancy rate control I 14.6 vs. 29.8%, group I 9.1 vs. 31.3%). CONCLUSION: The adequate endometrial thickness is an important prognostic factor for implantation and is achieved with administration of estradiol supplement in patients with abnormally thin endometrium who responded to exogenous estradiol with endometrial thickness up to 7 mm in evaluation cycle.

Effectiveness of Estradiol and Sildenafil supplement therapy in IVF-ET patients with thin endometrium / 대한산부인과학회잡지

OBJECTIVE: The purpose of this study was to evaluate the effect of estradiol (E2) only/and sildenafil supplement on controlled ovarian hyperstimulation and pregnancy outcome in patients undergoing IVF-ET cycles. METHODS: Total 104 cycles of IVF-ET patients were included in this study, which had been undergone controlled ovarian hyperstimulation (COH) with long protocol in Eulji infertility center and Ilsan Grace hospital between January 1999 and December 2000. Group 1 (COH only) consisted of 34 cycles, group 2 (COH+estradiol supplement) consisted of 35 cycles, and group 3 (COH+estradiol/sildenafil supplement) consisted of 35 cycles. RESULTS: With E2 and/only Sildenafil supplement, improvement of the endometrial thickness (P<0.05) and clinical pregnancy rate (P<0.05) were obtained. There was no significant increase in pregnancy rate with sildenafil supplement compared to E2 supplement only (20.0% versus 25.7%). However, rather short duration of controlled ovarian hyperstimulation (13.3+/-1.7 days versus 11.7+/-1.7 days) was found in the group that received E2 and sildenafil supplementation. (P<0.1) CONCLUSION: In patients with thin endometrium, the sildenafil supplement might lead to increase endometrial receptivity, and in consequence improvement of pregnancy rate. Sildenafil may augment the vasodilatory effect of nitric oxide by inhibition of cGMP hydrolysis, by improving ovarian perfusion, stimulates follicular development thus might shorten the duration of controlled ovarian hyperstimulation in IVT-ET cycles as we observed in our study.

Clinical Analysis on Emergency Postpartum Hysterectomy / 대한주산의학회잡지

OBJECTIVE: To analyze incidence, indications, risk factors, complications, and neonatal outcomes of emergency postpartum hysterectomies performed at EulJi University Medical Center. METHODS: A retrospective study of all cases of postpartum hysterectomies between May. 1996 and Dec. 2000. was carried out. RESULTS: 37 cases of postpartum hysterectomies during this period were performed, for overall incidnce of 2.3 per 1000 deliveries. Incidence after vaginal delivery and cesarean section was 0.03% and 0.52% respectively. The rate of postpartum hysterectomy increased with increasing age and parity. The main indications were placental disorders(54.1%) including placenta previa and adherent placenta, uterine atony(37.8%), uterine myoma(5.4%) and uterine rupture(2.7%) in order. The relative risk of postpartum hysterectomy according to the risk factors was 97.6(95% confidence interval 52.17-184.06) for placental disorders, 16.3(95% confidence interval 4.94-52.31) for cesarean section and 2.4(95% confidence interval 1.21-4.76) for previous cesarean section. The mean amount of transfuion was 17.1 pints. Although no maternal mortality had occurred, 16 patients(43.2%) had complica-ions including respiratory complication(13.5%), hemorrhagic complication(10.8%), infection(8.1%) and urologic injury(8.1%). Regarding fetal outcome, 2 of 38 infants(1 case, twin) were stillborn (5.3%) and 10 infants(26.3%) were suffered from various illness including prematurity, sepsis, meningitis, and brain hemorrhage. CONCLUSION: The data identifies placental disorders are the leading cause of postpartum hysterectomy. Although postpartum hysterectomy is a necessary life-saving operation, maternal morbidity remained high.
