Use of Combined Oral Contraceptives in Perimenopausal Women / 전남의대학술지

While perimenopausal women have low fecundity, they are still capable of becoming pregnant and the majority of pregnancies occurring during perimenopause are unintended pregnancies. Therefore, even during perimenopause, contraception must be used if unintended pregnancies are to be avoided. However, many perimenopausal women and healthcare providers believe that older people should not take combined oral contraceptives (COC) because doing so may be dangerous. However, to date, there is no evidence that taking COC presents an increased risk of cardiovascular events or breast cancer for middle-aged women as compared to other age groups, and in their recommendations, the Centers for Disease Control and Prevention (CDC) also do not list age itself as a contraindication for COC. Perimenopausal women often experience menstrual irregularity, heavy menstrual bleeding, and vasomotor symptoms. Taking COCs can help control these symptoms and significantly reduce the risk of ovarian cancer, endometrial cancer, and colorectal cancer. The objective of the present review is to examine the usage methods of COC among perimenopausal women and the health issues that may arise from taking COC in perimenopausal women.

Thyroid dysfunction and subfertility / 대한생식의학회지

The thyroid hormones act on nearly every cell in the body. Moreover, the thyroid gland continuously interacts with the ovaries, and the thyroid hormones are involved in almost all phases of reproduction. Thyroid dysfunctions are relatively common among women of reproductive age, and can affect fertility in various ways, resulting in anovulatory cycles, high prolactin levels, and sex hormone imbalances. Undiagnosed and untreated thyroid disease can be a cause of subfertility. Subclinical hypothyroidism (SCH), also known as mild thyroid failure, is diagnosed when peripheral thyroid hormone levels are within the normal reference laboratory range, but serum thyroid-stimulating hormone levels are mildly elevated. Thyroid autoimmunity (TAI) is characterized by the presence of anti-thyroid antibodies, which include anti-thyroperoxidase and anti-thyroglobulin antibodies. SCH and TAI may remain latent, asymptomatic, or even undiagnosed for an extended period. It has also been demonstrated that controlled ovarian hyperstimulation has a significant impact on thyroid function, particularly in women with TAI. In the current review, we describe the interactions between thyroid dysfunctions and subfertility, as well as the proper work-up and management of thyroid dysfunctions in subfertile women.

Comparison of oxidative stress markers in umbilical cord blood after vaginal and cesarean delivery

OBJECTIVE: The purpose of our study was to investigate the effect of the mode of delivery on the oxidant and antioxidant system in umbilical cord blood. METHODS: We performed gas analysis of umbilical venous blood and umbilical arterial blood immediately after delivery in 38 women; eighteen women had a vaginal delivery while 20 women delivered via cesarean section at over 37 weeks gestation. We examined lipid peroxide concentration by thiobarbituric acid reaction, protein carbonyl content by 2,4-dinitrophenylhydrazine reaction, and total antioxidant capacity by oxygen radical absorbance capacity assay. RESULTS: Lipid peroxide levels in umbilical venous blood were significantly higher in patients delivering by planned cesarean section (1.81 +/- 0.06 nmol/mg protein) than those with vaginal delivery (1.24 +/- 0.05 nmol/mg protein) (P < 0.05). Antioxidant capacity in umbilical venous blood was significantly higher in patients delivering by planned cesarean section (119.70 +/- 0.13 microM/microL) than those with a vaginal delivery (118.70 +/- 0.29 microM/microL) (P < 0.05). There was no significant difference in the carbonyl content of umbilical venous blood or in the lipid peroxide, carbonyl content, and total antioxidant capacity of umbilical arterial blood. CONCLUSION: Lipid peroxidation levels and antioxidant capacity in umbilical venous blood were higher in patients delivering by planned cesarean section than those with a vaginal delivery. Therefore, we propose that both the mother and neonate are exposed to higher oxidative stress during cesarean section delivery.

Expression of peroxiredoxin I regulated by gonadotropins in the rat ovary / 대한생식의학회지

OBJECTIVE: Peroxiredoxins (Prxs) play an important role in regulating cellular differentiation and proliferation in several types of mammalian cells. This report examined the expression of Prx isotype I in the rat ovary after hormone treatment. METHODS: Immature rats were injected with 10 IU of pregnant mare's serum gonadotropin (PMSG) to induce the growth of multiple preovulatory follicles and 10 IU of human chorionic gonadotropin (hCG) to induce ovulation. Immature rats were also treated with diethylstilbestrol (DES), an estrogen analogue, to induce the growth of multiple immature follicles. Northern blot analysis was performed to detect gene expression. Cell-type specific localization of Prx I mRNA were detected by in situ hybridization analysis. RESULTS: During follicle development, ovarian Prx I gene expression was detected in 3-day-old rats and had increased in 21-day-old rats. The levels of Prx I mRNA slightly declined one to two days following treatment with DES. A gradual increase in Prx I gene expression was observed in ovaries obtained from PMSG-treated immature rats. Furthermore, hCG treatment of PMSG-primed rats resulted in a gradual stimulation of Prx I mRNA levels by 24 hours (2.1-fold increase) following treatment, which remained high until 72 hours following treatment. In situ hybridization analysis revealed the expression of the Prx I gene in the granulosa cells of PMSG-primed ovaries and in the corpora lutea of ovaries stimulated with hCG for 72 hours. CONCLUSION: These results demonstrate the gonadotropin and granulosa cell-specific stimulation of Prx I gene expression, suggesting its role as a local regulator of follicle development.

Complications Following Outside-in and Inside-out Transobturator-Tape Procedures with Concomitant Gynecologic Operations / 전남의대학술지

This study was undertaken to compare the complications of outside-in transobturator tape procedures (TOT) and inside-out transobturator tape procedures (TVT-O) with concomitant gynecologic surgery for the treatment of female stress urinary incontinence (SUI). A retrospective review of 206 consecutive patients who underwent either TOT or TVT-O with concomitant gynecologic operations between March 2008 and February 2011 was conducted. The incidence of perioperative complications was compared. For statistical analysis, chi-squared tests were used. There were no reports of intraoperative complications such as vaginal injury or bladder perforation. Postoperative complications were noted in 23 procedures (11.2%). These included 6 cases of urinary retention (2.9%), 2 cases of vulva hematoma (1.0%), 7 cases of urinary tract infection (3.4%), 4 cases of de novo urgency (2.9%), and 4 cases of vaginal erosion (2.9%). There were no significant differences in complication rates between the two groups. Our results suggest that inside-out and outside-in procedures are simple and safe techniques that may have a low rate of complications when used with a concomitant gynecologic operation.

The National Use of Hormonal Therapy in Postmenopausal Women in 2010 / 대한폐경학회지

OBJECTIVES: To analyze the domestic consumption of postmenopausal hormonal medicine in the year 2010 and compare it with those since 2002. METHODS: Data from Intercontinental Marketing Services were used to analyze the consumption of hormonal medicine in the year 2010. Total hormonal medicines consisted of estrogen (ET), estrogen+progestogen (EPT), and Tibolone. We compared the respective consumption of hormonal medicines in the year 2010 with those since 2002. The percentage and frequency of usage of ET, ET/EPT, and tibolone in the year 2010 were also estimated. RESULTS: We found that 4.5% of women over 50 years of age had taken the postmenopausal hormonal medicine in the year 2010. The usage rate of each medicine showed 60% for ET/EPT compound, and 40% for Tibolone. The usage of postmenopausal hormonal medicine in 2010 increased by 7% compared to the previous year reaching 3.81 billion Korean won. There was 9% increase in the use of ET/EPT compound, and 4% increase in Tibolone. CONCLUSION: The total consumption of postmenopausal hormonal medicine was markedly decreased between 2002 and 2007. Since 2007, however, it has been steadily increasing from 3.01 billion to more than 3.81 billion Korea won in 2010, which maybe due to the reappraisal of the WHI study results, the change of doctor's recognition, and the increased consumption of Tibolone. When initiating postmenopausal hormone replacement therapy, the risk-benefit of hormonal therapy should be thoroughly explored.

Complications Following Outside-in and Inside-out Transobturator-Tape Procedures with Concomitant Gynecologic Operations / 전남의대학술지

Evaluation of length, volume and gray-scale histogram of the cervix as predictors of successful induction / 대한산부인과학회지

OBJECTIVE: The aim of this study was to evaluate whether the Bishop score, length, volume and gray-scale histogram of the cervix has a predictive value of assessing the rate of success in trial of induction. METHODS: Forty-one nulliparous patients with its Bishop score six or less were enrolled for this prospective study. All were on prostaglandin E2 (PGE2, Propess(R); Controlled Therapeutics Ltd) pessary. Three-dimensional transvaginal ultrasound scans of the cervix were performed on the ACCUVIX XQ (Medison) to measure length, volume, and gray-scale histogram. Bishop score was determined by digital examination. The successful induction was defined as the ability to achieve the active phase of labor corresponding to a cervical dilatation of > or =4 cm within 12 hours of removing the PGE2 pessary. The receiver operating characteristics (ROC) curves were also used to estimate an optimal cutoff point for the Bishop score, length, volume, and gray-scale histogram of the cervix. Logistic regression analysis was used for statistical analyses. RESULTS: The overall successful rate of labor induction was 73.2% (30/41). Multiple logistic regression analyses demonstrated that the value of anterior lip histogram was significantly associated with the successful labor induction. ROC curve for anterior lip histogram value in predicting success of induction indicated a significant relationship with successful induction. The best cutoff value was 69.4. CONCLUSION: The value of anterior lip histogram associates significantly with the prediction of successful induction in nulliparous women. But, Bishop score and other sonographic measurement of cervical length, volume, and posterior lip histogram have no predictive values for successful induction.

Update on the management of pelvic inflammatory disease / 대한산부인과학회지

Pelvic inflammatory disease (PID), the infection and inflammation of a woman's upper genital tract, is a frequent cause of infertility, ectopic pregnancy, and chronic pelvic pain among women of childbearing age. The management of PID has been largely based on the protocols issued by national or international institution. These guidelines recommended a broad-spectrum antibiotherapy in which quinolones continue to hold a key place. Yet, several significant facts such as the increase of quinolone-resistant gonococci and the emergence of 'new' pathogens have recently led us to reconsider the paradigms of the management of PID. This article reviewed lately published literatures on new bacteriological finding and recent antibiotics trials to delinate optimal regimen in managing PID.

Lipid peroxidation and total antioxidant ability in venous plasma and amniotic fluid of pregnant women with preterm premature rupture of membranes / 대한산부인과학회지

OBJECTIVE: To evaluate their roles in the pathophysiology of preterm premature rupture of membranes (PPROM), we checked interleukin (IL)-6, lipid peroxide, oxygen-radical absorbance capacity (ORAC) and antioxidant vitamin in the venous plasma and amniotic fluid of women with PPROM. METHODS: Venous plasma and amniotic fluid was taken from 20 normal pregnant women and 20 PPROM pregnancy women. IL-6 levels was determined by enzyme-linked immunosorbent assay. Lipid peroxide levels were measured by thiobarbituric acid reaction. The ORAC levels and the antioxidant levels were measured by Cao's method and by high performance liquid chromatography. RESULTS: The IL-6 levels in the venous plasma and amniotic fluid of PPROM pregnancy women were significantly higher than normal pregancy (P<0.01, P<0.01). The lipid peroxide levels in the venous plasma and amniotic fluid of PPROM pregnancy women were significantly higher than normal pregancy (P<0.01, P<0.01). The ORAC values in the venous plasma and amniotic fluid of PPROM pregnancy women were significantly higher than normal pregancy (P<0.01, P<0.01). The ORAC values/lipid peroxide levels in the venous plasma and amniotic fluid of PPROM pregnancy women were significantly higher than normal pregancy (P<0.01, P<0.01). The ascorbic acid levels in the venous plasma and amniotic fluid of PPROM pregnancy women were significantly higher than normal pregancy (P<0.05, P<0.01). CONCLUSION: This result suggest that the increased inflammatory bioactivity, increased lipid peroxidation and decreased antioxidant activity may be involved in the pathophysiology of PPROM. Low levels of ascorbic acid appears to be an important determinant of PPROM.

Changes in lipid peroxidation and protein oxidation by antibiotic therapy in the maternal venous plasma of preterm premature rupture of membranes / 대한산부인과학회지

OBJECTIVE: To investigate and compare the amount of the lipid peroxidation and the protein carbonyls formation in maternal venous plasma of preterm premature rupture of membranes (PPROM) during antibiotics administration. METHODS: PPROM were selected between 25 and 32 weeks of gestation. Eighteen patients (group 1) were treated with amoxicillin and erythromycin for 7 day period, 18 patients (group 2) were treated with 3rd generation cephalosporin (cefodizime, cefditoren) and erythromycin for the same period. Maternal blood were obtained from the two groups before and after the antibiotics administration, day 3 and day 7. Lipid peroxidation levels and protein carbonyl contents were measured by thiobarbituric acid reaction and 2,4-dinitrophenyl hydrazine method. Other 18 women with normal pregnancy between 25 and 32 weeks of gestation of venous blood were checked same things in vitro. Interleukin (IL) -6 was measured by enzyme-linked immunosorbent assay. RESULTS: 1. The lipid peroxidation levels and protein carbonyls formation in the maternal venous plasma of PPROM was significantly higher than that of normal pregnancy (lipid peroxidation levels; 4.77+/-.36 vs 7.11+/-.41 nmol/mg protein, P<001, protein carbonyls formation; 3.55+/-.22 vs 5.69+/-.30 nmol/mg protein, P<001). 2. There were no significant differences in the lipid peroxidation levels and protein carbonyls formation of the maternal venous plasma with PPROM mixed and incubated by amoxicillin, cefodizime, cefditoren, and erythromycin (in vitro). 3. There were no significant differences in the lipid peroxidation levels and protein carbonyls formation of the venous plasma of group 1 between before and after antibiotics administration, day 3 and day 7. 4. There were no significant differences in the lipid peroxide levels of the venous plasma of group 2 between before and after antibiotics administration, day 3 and day 7. 5. The protein carbonyls formation in the venous plasma of group 2 was significantly decreased at day 3 and day 7 after antibiotics administration than that of before (6.04+/-.44 and 5.53+/-.37 vs. 7.04+/-.51 nmol/mg protein, P<005). 6. The levels of IL-6 in the venous plasma of group 2 was significantly decreased at day 7 after antibiotics administration than that of before (7.50+/-.35 vs. 3.13+/-.37 pg/mL, P<005). CONCLUSION: In the maternal venous plasma of PPROM, the lipid peroxidation levels and protein carbonyls formation were increased. The formation of protein carbonyls and IL-6 in the maternal blood of PPROM was decreased by combined treatment of 3rd generation cephalosporin and erythromycin. The results suggest that reactive oxygen species formation by inflammatory reaction is suppressed by the 3rd generation cephalosporins and erythromycin combined treatment.

A case of ureterouterine fistula as a complication of cesarean section / 대한산부인과학회지

Ureteral injury is usually iatrogenic in origin, in particular as a result of laparoscopic or gynecological surgery. Ureterouterine fistula constitute a rare subset of iatrogenic genitourinary fistulas. The most common presentation of ureterouterine fistula is in women who have had a cesarean section. The management options include conservative therapy (spontaneous healing), endourologic (stented repair) or open surgical operation (ureteroneocystostomy or ureteroureterostomy). Herein, we report on a case of ureterouterine fistula in a 33-year-old woman who underwent a cesarean section. The 17th day after the operation, she complained watery vaginal discharge. Clinical and urographic assessments revealed an iatrogenic ureterouterine fistula and an ureteroneocystostomy was performed after 3 months.

Changes of antioxidant levels in the uterine venous plasma amniotic fluid, and chorioamnion after maternal supplementation with vitamin C and vitamin E / 대한주산의학회잡지

PURPOSE:To investigate the change in the antioxidant vitamin levels in maternal uterine venous plasma (MUVP), amniotic fluid (AF), and chorioamnion after vitamin C and E supplementation during pregnancy. METHODS:Thirty pregnant women who were scheduled for elective cesarean section between 37 and 39 gestational weeks were randomized in this study. Fifteen women were given a daily oral dose of vitamin C 1,000 mg and vitamin E 400 IU from 33~34 gestational weeks to delivery. The other fifteen women were not given, as a control group. Maternal uterine venous blood, AF, and chorioamnion were obtained after cesarean section. Lipid peroxides and oxygen-radical absorbance capacity value were measured by thiobarbituric acid reaction and Cao's method respectively. Ascorbic acid, uric acid, beta-carotene, retinol, alpha-tocopherol, and gamma-tocopherol were measured by high performance liquid chromatography. The tissue sections of chorioamnion were stained with hematoxylin-eosin and Masson-trichrome stain, and immunohistochemical stain for collagen type IV was also performed. RESULTS:The lipid peroxide levels in MUVP of the study group were significantly lower than those of the control group but in contrast, ORAC (Oxygen-radical absorbance capacity) values were lower in the control group. The alpha-tocopherol levels in MUVP, AF, and chorioamnion study group were significantly higher than those of the control group. Amniotic membrane and subepithelial stromal tissue in the study group were thicker than those in the control group. And subchorionic type IV collagen of placenta tissue in the study group was more stained than that of the control group. CONCLUSION:Maternal vitamin C and E supplementation may be beneficial in the prevention of diseases caused by oxidative stress such as preeclampsia and PROM and in increasing fibrin and type IV collagen in chorioamnion.

Effect of vitamin C and E on the lipid peroxide, antioxidant ability, and antioxidant vitamin levels in maternal and umbilical venous plasma / 대한산부인과학회지

OBJECTIVE: This controlled trial investigated the effect of supplementation with vitamins C and E on the lipid peroxide, antioxidant ability, and antioxidant vitamin levels in full term maternal and umbilical venous plasma. METHODS: Forty pregnant women were randomized in this study. They were nulliparous or multiparous women with history of preeclampsia or preterm premature rupture of membranes (PPROM). Twenty women were given vitamin C (1,000 mg/day) and vitamin E (400 IU/day) from 15~20 gestational weeks to delivery. The others were not given, as a control group. Maternal venous blood was obtained before vitamin supplementation and just before delivery. Umbilical venous blood was obtained after delivery. Lipid peroxide level and oxygen-radical absorbance capacity (ORAC) were measured by thiobarbituric acid reaction and Cao's method, respectively. Ascorbic acid, uric acid, beta-carotene, retinol, alpha-tocopherol, and gamma-tocopherol were measured by high performance liquid chromatography. Results: Supplementation with vitamins C and E was associated with decrease in lipid peroxide levels and increase in ORAC values and alpha-tocopherol levels in maternal venous plasma. And it was also associated with decrease in lipid peroxide levels and increase in ORAC values and alpha-tocopherol levels in umbilical venous plasma. CONCLUSION: Supplementation with vitamins C and E may be beneficial in the prevention of oxidant-antioxidant imbalance origin diseases such as preeclampsia, PPROM. And it also may affect antioxidant ability of the fetus.

Successful full-term delivery after abdominal radical trachelectomy and concurrent cervicoisthmic cerclage for early stage cervical cancer: Two cases / 대한산부인과학회지

Since the screening tool was introduced, the incidence and mortality of cervical carcinoma has decreased. However, the incidence of early stage cervical cancer is increasing in young women who want to preserve their fertility. The risk of preterm delivery after trachelectomy is high and remains problematic. Herein we report two patients who had successful full-term delivery after abdominal radical trachelectomy and concurrent cervicoisthmic cerclage for early stage cervical cancer.

Changes of lipid peroxide levels and prooxidative activity stimulating the protein carbonyl formation in the amniotic fluid of women with preterm premature rupture of membranes / 대한산부인과학회지

OBJECTIVE: To investigate the lipid peroxide levels and protein carbonyls levels in the amniotic fluid of pregnant women with preterm premature rupture of membranes (PPROM). METHODS: The lipid peroxide levels in the amniotic fluid of normal pregnancy (n=20) and pregnant women with PPROM (n=20) were measured by thiobarbituric acid reaction. The protein carbonyl contents in the amniotic fluid of normal pregnancy (n=20) and pregnant women with PPROM (n=20) were determined by the 2,4-dinitrophenylhydrazine method. After amniotic fluid of them were mixed and incubated up to 5 hours with 0.2 mL of 1mM moxalactam, cefodizime, amoxacillin, erythromycin, the lipid peroxide levels and protein carbonyl contents in them were measured. RESULTS: 1. The lipid peroxide levels in the amniotic fluid of pregnant women with PPROM was significantly higher than that of normal pregnancy (9.74+/-0.48 vs. 7.20+/-0.38 nmol/mg protein, P<0.01). 2. The protein carbonyl levels in the amniotic fluid of pregnant women with PPROM was significantly higher than that of normal pregnancy (13.0+/-0.33 vs. 11.27+/-0.17 nmol/mg protein P<0.01). 3. The lipid peroxide levels and protein carbonyls formation by moxalactam in the amniotic fluid of pregnant women with PPROM was significantly higher than basal level (12.08+/-0.81 vs. 9.74+/-0.48 nmol/mg protein, 20.08+/-0.66 vs. 13.0+/-0.33 nmol/mg protein, P<0.01). 4. The lipid peroxide levels and protein carbonyls formation by cefodizime in the amniotic fluid of pregnant women with PPROM was significantly lower than basal level (5.04+/-0.33 vs. 9.74+/-0.48 nmol/mg protein, 9.76+/-0.35 vs. 13.0+/-0.33 nmol/mg protein, P<0.01). 5. There were no significant differences in the levels of lipid peroxide and protein carbonyls by amoxacillin and erythromycin in the amniotic fluid of pregnant women with PPROM between antibiotics-induced and basal levels. CONCLUSION: The lipid peroxidation and the protein carbonyls formation were increased in the amniotic fluid of pregnant women with PPROM. Antibiotics-induced lipid peroxide and protein carbonyl levels were changed in the amniotic fluid of pregnant women with PPROM. Further studies on our results may be beneficial in the selection of antibiotics for pregnant women with PPROM.

Diagnostic role of HPV DNA chip test in patient with atypical glandular cell cytology / 대한산부인과학회지

OBJECTIVE: This study was aimed to identify the diagnostic role of HPV DNA chip test that may predict high grade lesions in gladular cell abnormalities on cervical cytology. METHODS: This study was performed in 88 patients, who were reported for atypical glandular cells on liquid-based cytologic test and was done subsequent cervical biopsies in Chonnam National University Hospital, between January 2003 and June 2007. HPV DNA chip test was performed on residual material of previous liquid-based cytologic test. And it was compared with pathologic results. RESULTS: Of the 88 patients with atypical glandular cells, the distribution was as follows: 60 patients were reported as atypical glandular cells, not otherwise specified (AGC, NOS), 28 patients were reported as atypical glandular cells, favor neoplastics (AGC, favor neoplastics). Of the 88 patients with an AGC result, pathologic results were as follows: 47 patients (53.4%) had a clinically significant high grade lesions. Of this high grade lesions, 5 cases of high grade squamous intraepithelial lesion, CIN 2 & CIN 3 (83.4%, 5/6), 2 cases of SCC (66.7%, 2/3), 4 cases of AIS (80.0%, 4/5), and 11 cases of endocervical adenocarcinoma (69%, 11/16) were positive on HPV DNA chip test. The sensitivity of human papilloma virus positivity to predict the presence of high grade lesion in cervix was 73.3%, specificity 85.3%, positive predictive value 78.5%, and negative predictive value 81.3%. There were 16 patients with endometrial cancer. Only 3 patients were HPV DNA chip positive. CONCLUSION: HPV DNA detection was strongly associated with high grade lesions in women with atypical glandular cells on cervical pap smear. These results suggest that although there is no high grade lesion in patients with HPV positive AGC-NOS at initial work-up, meticulous search like cone biopsy should be done to find high grade lesion. If the women with a diagnosis of AGC on pap smear are over 35 years of age and has abnormal utero-vaginal bleeding, this patients needed to be evaluated with endometrial biopsy.

Diagnostic efficacy of saline infusion sonohysterography and hysteroscopy for intrauterine lesion / 대한산부인과학회지

OBJECTIVE: To compare the diagnostic accuracy and acceptability of saline infusion sonohysterography (SIS), and hysteroscopy for detecting intracavitary abnormalities in women with abnormal uterine bleeding. METHODS: Seventy-eight patients with abnormal uterine bleeding were selected from the Department of Obstetrics and Gynecology in Chonnam University Hospital. The findings at SIS were compared with the hysteroscopic and histologic findings. The agreement of diagnosis between SIS and hysteroscopy was calculated. Sensitivity, specificity, positive predictive value, and negative predictive value were calculated. RESULTS: SIS had a sensitivity of 84% and a specificity of 85% for a diagnosis of endometrial polyp. Hysteroscopy had a sensitivity of 86% and a specificity of 96% for diagnosis of endometrial polyp. SIS had a sensitivity of 75% and a specificity of 86% for a diagnosis of submucosal myoma. Hysteroscopy had a sensitivity of 100% and a specificity 99% for a diagnosis of submucosal myoma. SIS had a sensitivity of 91% and a specificity of 96% for a diagnosis of submucosal myoma. Hysteroscopy had a sensitivity of 100% and a specificity 91% for a diagnosis of endometrial hyperplasia. CONCLUSIONS: The diagnostic accuracy of SIS was significant to that of hysteroscopy in diagnosing intracavitary abnormalities, Moreover, SIS in a safe, convenient, cost effective, easily accessible and acceptable investigative modality.

One case of prenatally diagnosed vasa previa accompanied by succenturiate placenta / 대한산부인과학회지

Vasa previa is said to occur when fetal vessels, unsupported by placenta or umbilical cord, transverse the menbranes over the cervix, below the presenting part. It is typically caused by velamentous insertion of the umbilical cord with fetal vessels between the cervix and presenting part. Bilobed or succenturiate placentas also can be associated with aberrant vasculature over the internal cervical os. Vasa previa has an incidence of approximately one per 2,000-5,000 deliveries. It has a high fetal mortality due to fetal exsanguination resulting from fetal vessels tearing when the menbranes rupture. So Prenatal detection of vasa previa is very important. We believe transvaginal ultrasound in combination with color Doppler is the most effective tool in the antenatal diagnosis of vasa previa. Recently, we experienced one case of vasa previa accompanied by succenturiate placenta diagnosed prenatally by color Doppler and transvaginal sonography. Here we report our experience with a literature review.

Primary Epithelial Ovarian Carcinoma with Gastric Metastasis Mimic Gastrointestinal Stromal Tumor / Journal of the Korean Cancer Association, 대한암학회지

Epithelial ovarian carcinoma rarely metastasizes to the parenchyma of the stomach. A 55-years-old woman presented with epigastric pain and a feeling of fullness for one month. A subsequent contrast-enhanced CT scan demonstrated a 4.5 x 4 cm submucosal mass with focal ulceration in the gastric antrum, and this finding was suggestive of GIST. After gastric antrectomy, the final pathology showed metastatic gastric tumor from a primary ovarian serous carcinoma. Because epithelial ovarian carcinoma is usually spread along the peritoneal surface, stomach involvement is rare. Furthermore, transmural gastric metastasis is very rare in a patient with primary ovarian carcinoma. Until now, there has been no reported case of stomach involvement at presentation in a patient with primary ovarian carcinoma. We present here a case of ovarian carcinoma with gastric metastasis that mimicked GIST.
