Complete vaginal outlet stenosis in a patient with Sheehan’s syndrome.

Obstetrics & Gynecology Science.2016;59(6):559-561. doi:10.5468/ogs.2016.59.6.559

We present a case of complete vaginal stenosis in a woman diagnosed with Sheehan’s syndrome. The patient delivered at full-term 5 months prior, and experienced massive postpartum bleeding at that time. During evaluation of persistent amenorrhea, we found that her vaginal orifice was completely adhesive and obstructed. Prior to corrective surgery, we managed the patient with an oral contraceptive to induce uterine bleeding into the vaginal outflow tract. After three cycles of an oral contraceptive, we could confirm that there was no stenotic lesion in the vaginal cavity as a hematocolpos was created. Adhesiolysis with scar revision for the vaginal stenosis was successfully performed; it was found that the lesion was limited to only the distal part of the vaginal outlet. Complete vaginal stenosis in reproductive age women with hypopituitarism has not been reported. The artificial induction of hematometrocolpos before surgery was useful in determining the extent of the stenotic lesion, and assured safety.

OBJECTIVE: The aim of this study was to describe the principle of the Cheil HPV DNA Chip assay and evaluate its accuracy. In order to quantify the human papillomavirus (HPV) load and identify HPV genotypes simultaneously, this assay combined the two methods: SYBR Green quantitative real-time polymerase chain reaction (PCR) and DNA microarray. METHODS: We designed novel consensus primer sets that target the conserved region of the HPV L1 gene for quantifying and detecting a broad range of HPV types by quantitative real-time PCR. Subsequently, using the PCR products, DNA microarray was performed with 36 HPV type-specific probes. To validate this method, direct sequencing and correlation analysis among HPV genotype, viral load, and cytological abnormality was performed by Cohen’s kappa values, two-sided McNemar chi-square test, Kruskal-Wallis test, and odds ratios. RESULTS: The kappa value of the Cheil HPV DNA Chip was 0.963 (95% confidence interval, 0.919 to 0.98), which was significantly higher than the value of 0.527 (95% confidence interval, 0.447 to 0.59) obtained using a conventional HPV DNA Chip. HPV16 (χ²=62.28, P<0.01), HPV33 (χ²=7.18, P<0.01), and HPV58 (χ²=9.52, P<0.01), which are classified as high-risk HPVs, were detected at significant levels in samples with high-grade lesions. And viral loads tended to be higher in groups with high odds ratios. CONCLUSION: The Cheil HPV DNA Chip is an effective diagnostic assay for simultaneously detecting HPV genotypes and loads in cervical samples.

Obstetrics & Gynecology Science.2016;59(6):479-488. doi:10.5468/ogs.2016.59.6.479

OBJECTIVE: The management of cervical intraepithelial neoplasia (CIN) and early invasive cancer of the uterine cervix is very difficult to approach, especially in case of young woman who wants to preserve her fertility. Conization of the cervix may have various kinds of disadvantage. The objective of this clinical retrospective study is to investigate the therapeutic effects and clinical efficacy of photodynamic therapy (PDT) including combined chemo-photodynamic therapy in patients with pre-malignant CIN and malignant invasive cervical cancer. METHODS: Total number of PDT trial case was 50 cases and total number of patient was 22 patients who registered to PDT clinic. We used photogem sensitizer and 632 nm diode laser in early two cases. After then we performed PDT using photofrin sensitizer and 630 nm diode laser in other cases. We used flat-cut, microlens, cylindrical diffuser, and interstitial type optic fibers in order to irradiate the lesions. 240 J/cm² energy was irradiated to the lesions. RESULTS: CIN 2 were 4 cases (18.2%) and CIN 3 were 15 (68.2%) and invasive cervical cancer were 3 (13.6%). Complete remission (CR) was found in 20 patients (91%). One case of 19 patients with CIN lesion recurred at 18 months after PDT treatment. CR was found in 18 cases in the patients with CIN lesions (95%). CR was found in 2 cases in the patients with invasive cervical cancer (67%). CONCLUSION: Our data showed that CR rate was fantastic in CIN group (95%). This study suggests that PDT can be recommended as new optimistic management modality on the patients with pre-malignant CIN lesions including carcinoma in situ and relatively early invasive cancer of the uterine cervix. Combined chemo-photodynamic therapy is essential in case of invasive cervical cancer. For the young age group who desperately want to preserve their fertility and have a healthy baby, PDT can be a beacon of hope.

Obstetrics & Gynecology Science.2016;59(6):470-478. doi:10.5468/ogs.2016.59.6.470

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.

Seung Mi LEE ; Jong Kwan JUN ; Su Jin SUNG ; Sung Il CHOO ; Jeong Yeon CHO ; Hye Jin YANG ; Chan Wook PARK ; Joong Shin PARK ; Hee Chul SYN

Obstetrics & Gynecology Science.2016;59(6):463-469. doi:10.5468/ogs.2016.59.6.463

OBJECTIVE: To investigate whether the uterine artery pulsatility index (UtA PI) of hypertensive pregnancies is higher than that of normal pregnancies in the puerperium, as well as in the antepartum period. METHODS: The UtA PI was measured in hypertensive (group 1) and normal pregnancies (group 2) during antepartum, immediate postpartum or late postpartum periods. Using the transvaginal approach, the bilateral uterine artery indices were measured. RESULTS: One hundred twenty-two women were enrolled: group 1, hypertensive disease in pregnancy (11 cases in antepartum, 13 cases in immediate postpartum and 10 cases in late postpartum period); group 2, normal pregnancies (32 cases in antepartum, 29 cases in immediate postpartum and 27 cases in late postpartum). In antepartum and immediate postpartum periods, the mean UtA PI and the proportion of cases with an early diastolic notch were higher in group 1 than in group 2 (antepartum mean UtA PI, 1.14 in group 1 vs. 0.68 in group 2, P<0.001; early diastolic notch, 46% vs. 9%, P<0.05; immediate postpartum mean UtA PI, 1.30 vs. 1.08, P<0.05; early diastolic notch, 85% vs. 48%, P<0.05). In late postpartum period, the mean value of UtA PI of group 1 was still higher than that of group 2, although the proportion of cases with an early diastolic notch was not different (mean UtA PI, 1.43 vs. 1.20, P<0.05; early diastolic notch, 60% vs. 52%, P=0.73). CONCLUSION: The UtA PI in hypertensive pregnancies was still higher than normal pregnancies in puerperal periods, suggesting that more than several weeks are required to resolve increased uterine artery vascular impedance.

Hee Sun KIM ; Soo Young OH ; Suk Joo CHOI ; Hyun Soo PARK ; Geum Joon CHO ; Jin Hoon CHUNG ; Yong Soo SEO ; Sun Young JUNG ; Jung Eun KIM ; Su Hyun CHAE ; Han Sung HWANG

Obstetrics & Gynecology Science.2016;59(6):454-462. doi:10.5468/ogs.2016.59.6.454

OBJECTIVE: The purpose of this case series was to retrospectively examine records of cases with uterine rupture in pregnancies following myomectomy and to describe the clinical features and pregnancy outcomes. METHODS: This study was conducted as a multicenter case series. The patient databases at 7 tertiary hospitals were queried. Records of patients with a diagnosis of uterine rupture in the pregnancy following myomectomy between January 2012 and December 2014 were retrospectively collected. The uterine rupture cases enrolled in this study were defined as follows: through-and-through uterine rupture or tear of the uterine muscle and serosa, occurrence from 24+0 to 41+6 weeks' gestation, singleton pregnancy, and previous laparoscopic myomectomy (LSM) or laparotomic myomectomy (LTM) status. RESULTS: Fourteen pregnant women experienced uterine rupture during their pregnancy after LSM or LTM. Preterm delivery of less than 34 weeks' gestation occurred in 5 cases, while intrauterine fetal death occurred in 3, and 3 cases had fetal distress. Of the 14 uterine rupture cases, none occurred during labor. All mothers survived and had no sequelae, unlike the perinatal outcomes, although they were receiving blood transfusion or treatment for uterine artery embolization because of uterine atony or massive hemorrhage. CONCLUSION: In women of childbearing age who are scheduled to undergo LTM or LSM, the potential risk of uterine rupture on subsequent pregnancy should be explained before surgery. Pregnancy in women after myomectomy should be carefully observed, and they should be adequately counseled during this period.

Obstetrics & Gynecology Science.2016;59(6):444-453. doi:10.5468/ogs.2016.59.6.444

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.

Differences in clinical presentation and pregnancy outcomes in antepartum preeclampsia and new-onset postpartum preeclampsia: Are these the same disorder?.

Gustavo VILCHEZ ; Luis R HOYOS ; Jocelyn LEON-PETERS ; Moraima LAGOS ; Pedro ARGOTI

Obstetrics & Gynecology Science.2016;59(6):434-443. doi:10.5468/ogs.2016.59.6.434

OBJECTIVE: New-onset postpartum preeclampsia is a poorly defined condition that accounts for a significant percentage of eclampsia cases. It is unclear whether new-onset postpartum preeclampsia is a different disorder from or belongs to the same spectrum of classic antepartum preeclampsia. The objective of this study was to compare the clinical presentation and pregnancy outcomes of antepartum preeclampsia and new-onset postpartum preeclampsia. METHODS: A retrospective study including 92 patients with antepartum preeclampsia and 92 patients with new-onset postpartum preeclampsia was performed. Clinical presentation and pregnancy outcomes were compared. Chi-square test was used to analyze categorical variables, and independent t-test and Mann-Whitney U-test for numerical variables. P-values of <0.05 were used to indicate statistical signifi cance. RESULTS: Patients with antepartum preeclampsia and new-onset postpartum preeclampsia differ significantly in profile, symptoms at presentation, laboratory markers and pregnancy outcomes. CONCLUSION: New-onset postpartum preeclampsia has a distinct patient profile and clinical presentation than antepartum preeclampsia, suggesting they may represent different disorders. Characterization of a patient profile with increased risk of developing this condition will help clinicians to identify patients at risk and provide early and targeted interventions to decrease the morbidity associated with this condition.

Obstetrics & Gynecology Science.2016;59(6):427-433. doi:10.5468/ogs.2016.59.6.427

OBJECTIVE: The cardiovascular system maintains homeostasis through a series of adaptive responses to physiological requirements. However, little is known about the adaptation of fetal cardiac function to gravity, according to gestational age. In the present study, we aimed to evaluate the adaptive responses of cardiac function to postural changes, using Tei index measurements. METHODS: Fetal echocardiography and Doppler examination were performed on 114 women with vertex singleton pregnancies at 19 to 40 weeks' gestation. Participants were placed in an upright seated position, and the Tei index for fetal left ventricular cardiac function was measured. The women were then moved into a supine position and the Tei index was re-measured. RESULTS: The mean Tei index when measured in an upright seated position was significantly lower than that measured in a supine positioning for all fetuses (0.528±0.103 vs. 0.555±0.106, P=0.014, respectively). This difference was also noted in fetuses with a gestational age of 28–40 weeks (0.539±0.107 vs. 0.574±0.102, P=0.011, respectively). However, there was no difference in the Tei index between an upright seated and a supine position among fetuses with a gestational age of <28 weeks (0.505±0.091 vs. 0.516±0.103, P=0.571, respectively). CONCLUSION: Postural changes from an upright seated to a supine position result in an increased Tei index after a gestational age of 28 weeks. This appears to reflect maturation in the adaptive responses of the fetal cardiovascular system to postural changes.

Chae Hee SIM ; Jin Hee LEE ; Jyung Sik KWAK ; Seung Hun SONG

Obstetrics & Gynecology Science.2014;57(6):560-563. doi:10.5468/ogs.2014.57.6.560

Leiomyomas are common benign uterine tumors. However, the incidence of vaginal myoma is very rare and may be confused with a variety of vaginal tumors. We report a case of 43-year-old nulligravida who presented with a protruding painful vaginal mass for 7 days. The mass had initially appeared 3 years prior, as 2 to 3 cm that had not subsequently increased. However suddenly, there was rapid severe enlargement over the course of 7 days. Physical exam revealed a monstrous shaped, black color with focal necrosis, odorous protruding vaginal mass about 7 cm in size. The vaginal mass was infected and degenerated. And vaginal wall was also destroyed by the enlarged mass. Because of the clinical features and radiologic findings, the preoperative diagnosis was a vaginal malignancy. We reported an extremely rare case of vaginal myoma that had several characteristics of malignancy, with a brief review of the literature.
