Materials and methods: We conducted online survey in February 2016 with questions to 2000 women aged between 9 and 59 years in South Korea by distribution of age and region, to assess HPV uptake and associated correlates such as age, residential region, education, and socioeconomic status. Results: The overall HPV vaccine received at least 1 dose rate was 23.1%, and the highest rate of vaccination was observed in women aged 20–29 years (38.6%), followed by those aged 30–39 years (36.9%), 9–19 years (16.9%), 40–49 years (14.2%), and 50–59 years (12.5%). Factors affecting HPV vaccination included metropolitan cities (odds ratio [OR] = 1.44, 95% confidence interval [CI], 1.15–1.80), university graduate (OR = 1.45, 95% CI, 1.06–2.00), regular influenza vaccination (OR = 2.11, 95% CI, 1.64–2.70), visited clinic within the last 6 months (OR = 1.73, 95% CI, 1.20–2.51) and high family income (OR = 1.55, 95% CI, 1.01–2.37). Conclusion: HPV vaccine uptake is low in South Korean women. Correct publicity, education and economic support programs for HPV vaccine could play an important role in increasing HPV vaccine uptake in South Korea.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46743587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Among 112 patients with atypical EH, 45 (40%) underwent hysteroscopy and 67 (60%) curettage. Results: The diagnostic accuracy of OH was very high: in particular, it showed a diagnostic coincidence in 87% of cases with the definitive histological diagnosis through hysteroscopy. The curettage, instead, had diagnostic coincidence only in 14% of cases.

Methods: This was a single-center, prospective, randomized, open-label, controlled trial recruiting 852 pregnant women with one or more PPH risk factors between April 2017 and August 2019. Pregnant woman who was scheduled for an elective cesarean section were randomly assigned to receive carbetocin or oxytocin for prevention of PPH. The primary efficacy endpoint was the proportion of additional uterotonics. Results: A total of 852 pregnant women were randomly assigned to receive carbetocin (n = 442) or oxytocin (n = 410). The baseline characteristics were comparable between the two groups. The carbetocin group had lower proportion of requiring additional uterotonics (18.4% vs. 24.4%, p = 0.03 in full analysis set [FAS] analysis) to the oxytocin group. The amount of blood loss (intrapartum or postpartum) was no statistically significant difference (all p > 0.05). There were no significant differences in the postpartum hemoglobin, rate of hemostatics, blood transfusion, additional surgical interventions or uterine massage between the two groups. The rates of mild asphyxia in carbetocin and oxytocin groups were 2.1% and 1.3%, respectively. No other poor maternal and neonatal outcomes were observed in two groups. Conclusions: Carbetocin required lower rate of additional uterotonics than oxytocin for prevention of PPH after elective cesarean section in Chinese high risk women. Carbetocin was comparable to oxytocin in postpartum blood loss, postpartum hemoglobin, hemostatics, blood transfusion, additional surgical interventions or uterine massage.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46673710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of these metrics was based on expert opinion that did not account for patients’ values. The ultimate aim of our research is to develop performance indicators for labour and birth that reflect the patient perspective. Methods: A qualitative interview design was used to engage a convenience sample, of recent (<1 year) postpartum patients, in semi-structured interviews, where they shared their experiences of their recent birth. Patients were also asked to assess descriptions of adverse perinatal outcomes for readability and comprehension, towards developing accurate unbiased descriptions for a subsequent survey of patients to weight complications. Responses were recorded, transcribed, coded and analyzed using thematic analysis. thematic analysis. Results: Five themes emerged during the analysis: (1) desire for patient-centred care, (2) improved communication, (3) labour/birth, expectations and outcomes, (4) care team support during labour and birth, (5) continuing emotional and physical postpartum care. Conclusions: Patient-centred care and good health outcomes were the major values expressed by the patients in this study. Good communication and shared decision making led to patients describing their labour and birth as a satisfying experience.

Takeda, Shiori Tsuge, S. Iyoshi","doi":"10.31083/j.ceog4901019","DOIUrl":"https://doi.org/10.31083/j.ceog4901019","url":null,"abstract":"Background: The similarities in clinical features between ruptured corpus luteum cyst (RCLC) with undiagnosed intrauterine pregnancy in the early first trimester (RCLC-P) and ruptured ovarian pregnancy are well established. However, the identification of differences between these two morbid conditions is important to determine the causes and manage the hemoperitoneum without devastation of pregnancy in RCLC-P. Furthermore, the pregnancy outcomes after laparoscopic surgery in women with RCLC-P are not recognized. Methods: Retrospective observational study of six women with RCLC-P and seven women with ruptured ovarian pregnancy. Results: All cases were referred under strong suspicion of ruptured ectopic pregnancy due to lower abdominal pain and positive urinary pregnancy test after spontaneous conception. The estimated median number of gestational weeks in RCLC-P (5 weeks) was significantly lower than that for ruptured ovarian pregnancy (7 weeks). At triage, the median serum levels of beta-human chorionic gonadotropin (β -hCG) were significantly lower in RCLC-P (592 IU/L) than ruptured ovarian pregnancy (3723 IU/L) (p = 0.01). In all six cases with RCLC-P, laparoscopic ovary-sparing surgerywas performed. Among the four womenwho received postoperative supplementation of progesterone, uneventful vaginal delivery occurred at term in three cases. Conclusions: Early gestational age and lower serum β -hCG levels at triage, as well as non-declining levels of serum β -hCG on the day after surgery, were significant predictors of RCLC-P rather than ruptured ovarian pregnancy. Laparoscopic surgery was a feasible option for the management of RCLC-P with appropriate postoperative luteal support to achieve successful obstetric outcomes.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47222880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, the authors aimed at analyzing the clinical and pathological aspects of all recently published ovarian carcinoid, providing new correlations regarding them. Mechanism: The authors have reviewed all cases of primary ovarian carcinoid reported in international journals since 2005 to date. A total of 99 cases published in 68 articles have been found and analyzed. Findings in brief: Our results up to 29.31% of patients presented with carcinoid heart disease, and 17.24% had an abdominal mass, which caused them to present to the physician. Patients presenting with metastases had more frequently the insular subtype (33.33%) and had similar median age as those without metastases. A teratoma component was noticed in 58.9% of cases and was also associated with the insular pattern of carcinoid. To our best knowledge, this paper includes the largest review of primary ovarian carcinoid to date. Conclusions: The incidence of carcinoid heart disease might have been underestimated up to this moment, thus, requiring further imagistic investigations of patients presenting with these symptoms. Additionally, the insular variant was most frequently associated with the presence of both teratoma (52.94%) and metastases (33.33%), although previous reports have noticed a higher incidence of teratoma in the mucinous variant. In our opinion, these apparently divergent results warrant further studies of this rare subtype of ovarian tumor.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49010133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 39-year-old woman at 7 weeks was diagnosed with a heterotopic cervical gestation, with intrauterine and cervical sac, both with live embryos. The ectopic pregnancy was successfully terminated with intrasacular injection of KCl, preserving the intrauterine pregnancy. At 32 weeks of gestation the patient started with a profuse bleeding from the cervical sac, causing maternal hypotension (80/45 mmHg) and tachycardia (160 bpm) and a decelerative pattern in the cardiotocographic fetal monitoring, prompting us to perform caesarean section. The cessation of bleeding was achieved using a double balloon intracervical catheter, which was withdrawn 24 hours after its insertion without observing a new bleeding episode. The patient was discharged after 8 days and the newborn after 35 days of life, both in good health.

Methods: The study was carried out on 30 volunteer women for whom evaluation of the uterine cavity and transit through the tubules was required due to infertility. In the evaluation of the hysteroscopic tubal passage, a 6Fr feeding cannula was advanced from the hysteroscope barrel, and firstly methylene blue and then an air bubble were applied to the fluid-filled uterine cavity through this flexible cannula. Results: When the reference method was taken as hysterosalpingography, the specificity of hysteroscopy was found to be 85.71% (95% CI (confidence interval): 42.13%– 99.64%), sensitivity 94.74% (95% CI: 85.38–98.90%). The positive predictive value of hysteroscopy was calculated as 98.18% (95% CI: 89.78%–99.70%) and the negative predictive value was 66.67% (95% CI: 38.96%–86.24%). Observing the bubble and swirl effect together in the evaluation of the tube opening increases the diagnostic accuracy. And benefit of hysteroscopy in the evaluation of tubal passage was statistically significantly higher than hysterosalpingography. Conclusion: Considering the cellular damages that can be caused by hysterosalpingraphy and the real observation power provided by hysteroscopy, simultaneous evaluation and the comfort of making intervention possible, hysteroscopy will be a more useful and useful application.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46248454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, management of unruptured interstitial pregnancy by uterine artery chemoembolization (UACE)with dactinomycin has never been evaluated via a case series. Methods: With this aim, a retrospective review of electronic chart records over a five-year period was performed, and a series of cases of unruptured interstitial pregnancy during the first trimester was extracted. Diagnostic procedures included ultrasonography, magnetic resonance imaging (MRI), and laparoscopic examination, if necessary. Conservative treatment regimen included UACE. Additional administration of methotrexate (MTX) was considered when an insufficient decline of serum β-hCG was noted. Clinical characteristics and treatment outcomes are described. Results: Among four women diagnosed with unruptured interstitial pregnancy at six weeks of gestation, one case was managed by laparoscopic cornuostomy due to concerns of rupture after the identification of thinning of the myometrium, whereas the other three cases were initially managed by UACE. One case of proximal interstitial pregnancy was diagnosed solely by MRI, whereas two cases of distal interstitial pregnancy was diagnosed by exploratory laparoscopy. Two cases were successfully managed by UACE alone, whereas one case required additional systemic administration of MTX to achieve resolution of gestational products after UACE. Thereafter, one patient conceived spontaneously and experienced a successful vaginal birth. Conclusions: This small case series emphasizes that UACE is a feasible minimally invasive option for the management of unruptured interstitial pregnancy identified in the early first trimester.","PeriodicalId":10312,"journal":{"name":"Clinical and experimental obstetrics & gynecology","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47006004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
