Chimeric Singleton Placenta Comprising Placental Mesenchymal Dysplasia and Complete Hydatidiform Mole with Live Birth and Postpartum Diagnosis of Gestational Trophoblastic Neoplasia.

INTRODUCTION: Placental mesenchymal dysplasia (PMD) is a benign lesion that is often misdiagnosed as complete (CHM) or partial hydatidiform mole. PMD usually results in live birth but can be associated with several fetal defects. Herein, we report PMD with CHM in a singleton placenta with live birth. CASE PRESENTATION: A 34-year-old gravida 2, para 1, living 1 (G2P1L1) woman was referred on suspicion of a molar pregnancy in the first trimester. Maternal serum human chorionic gonadotrophin levels were increased during early pregnancy, with multicystic lesions and placentomegaly observed on ultrasonography. Levels decreased to normal with no fetal structural abnormalities observed. A healthy male infant was delivered at 34 gestational weeks. Placental p57KIP2 immunostaining and short tandem repeat analysis revealed three distinct histologies and genetic features: normal infant and placenta, PMD, and CHM. Gestational trophoblastic neoplasia was diagnosed and up to fourth-line chemotherapy administered. CONCLUSION: Distinguishing PMD from hydatidiform moles is critical for avoiding unnecessary termination of pregnancy. CHM coexisting with a live fetus rarely occurs. This case is unique in that a healthy male infant was born from a singleton placenta with PMD and CHM.

Risk factors of menopause after allogeneic hematopoietic cell transplantation in premenopausal adult women.

OBJECTIVES: Allogeneic hematopoietic stem-cell transplantation (HCT) is the only curative option for most hematologic malignancies. However, HSCT can cause early menopause and various complications in premenopausal women. Therefore, we aimed to investigate risk factors predicting early menopause and its clinical implications among survivors post HCT. METHODS: We retrospectively analyzed 30 adult women who had received HCT at premenopausal status between 2015 and 2018. We excluded patients who had received autologous stem cell transplantation, had relapsed, or died of any cause within 2 years of HCT. RESULTS: The median age at HCT was 41.6 years (range, 22-53). Post-HCT menopause was identified in 90% of myeloablative conditioning (MAC) HCT and 55% of reduced-intensity conditioning (RIC) HCT (p = .101). In the multivariate analysis, the post-HCT menopausal risk was 21 times higher in a MAC regimen containing 4 days of busulfan (p = .016) and 9.3 times higher in RIC regimens containing 2-3 days of busulfan (p = .033) than that of non-busulfan-based conditioning regimens. CONCLUSIONS: Higher busulfan dose in conditioning regimens is the most significant risk factor affecting post-HCT early menopause. Considering our data, we need to decide on conditioning regimens and individualized fertility counseling before HCT for premenopausal women.

Prenatal Diagnosis of Right-Sided Congenital Ventricular Diverticulum (CVD) Assisted by Spatiotemporal Image Correlation (STIC) Acquisition and the Speckle-Tracking Technique to Assess Fetal Cardiac Function: A Case Report.

Congenital ventricular diverticulum (CVD) is a cardiac malformation defined as an outpouching lesion of a ventricle with normal contractility and thickness, and the advancement of prenatal sonography has led to its prenatal diagnosis. In the prenatal period, CVD is reported in association with pericardial effusion, arrhythmia, and fetal hydrops or as an isolated condition. With the development of prenatal echocardiography, CVD can be diagnosed from the early stage of pregnancy, and prenatal procedures, such as pericardiocentesis, are also possible. Spatiotemporal image correlation (STIC) acquisition, a novel approach for the clinical evaluation of fetal hearts, provides easy-to-use techniques for acquiring data from fetal hearts and helping visualization with two-dimensional and three-dimensional (3D) cine sequences. Furthermore, the speckle-tracking technique enables a more comprehensive evaluation of the shape, continuity, and function of the fetal heart. These recent techniques have never been used for CVD diagnosis and evaluation. Here, we present a case of right-sided CVD, which is the first in which STIC acquisition and cardiac function assessment with the speckle-tracking technique were used to assist in the diagnosis and evaluation.

The First Korean Siblings With Adult-Onset 4H Leukodystrophy Related to Nonsynonymous POLR3B Mutations.

Objectives: 4H leukodystrophy is a rare autosomal recessive hypomyelinating disorder characterized by several combinations of motor dysfunction, abnormal dentition, and ophthalmic and endocrine abnormalities. To date, only a single Korean case report of pediatric leukodystrophy caused by the POLR1C sequence variation has been published, while there are no reports on the POLR3B, POLR3A, or POLR3K variants. Methods: Genetic tests of Korean sibling pairs with primary amenorrhea due to normosmic isolated hypogonadotropic hypogonadism and cognitive or behavioral symptoms were performed by whole-exome sequencing (WES). The WES results were validated by direct Sanger sequencing. Results: We identified biallelic variations in the POLR3B gene of p.Tyr685* and p.Tyr746Cys, which have not been associated with 4H leukodystrophy. Both sequence variants lie in the hybrid-binding domain of the protein RPC2. The protein structure analysis predicted that cysteine substitution of the phylogenetically conserved amino acid tyrosine can cause destabilization. Discussion: The siblings reported are the first POLR3B-related hypomyelinating leukodystrophy cases in Korea. Our report expands the mutational spectrum of 4H leukodystrophy and suggests that it is mandatory to consider its diagnostic possibility in adult patients presenting with primary amenorrhea and mild cognitive or behavioral symptoms.

Successful Full-Term Delivery via Selective Ectopic Embryo Reduction Accompanied by Uterine Cerclage in a Heterotopic Cesarean Scar Pregnancy: A Case Report and Literature Review.

Heterotopic cesarean scar pregnancy (HCSP) is a combination of cesarean scar pregnancy (CSP) and intrauterine pregnancy (IUP). Cesarean scar pregnancy is accompanied by life-threatening complications, such as uterine rupture and massive bleeding. Herein, we present a case of HCSP treated with selective potassium chloride injection into the CSP under ultrasonography in association with uterine cerclage to control vaginal bleeding; this led to a successful IUP preservation and full-term delivery. Additionally, we will review several previous reports on HCSP management, including our case.

Ruptured Hemorrhagic Ectopic Pregnancy Implanted in the Diaphragm: A Rare Case Report and Brief Literature Review.

The mortality and morbidity rates of non-tubal ectopic pregnancies with abdominal hemorrhaging are 7-8 times higher than those of tubal pregnancies. Diaphragmatic pregnancy is a rare non-tubal ectopic form, causing acute abdominal hemoperitoneum. Here, we present a case of a primary diaphragmatic ectopic pregnancy with hemorrhage that was immediately diagnosed and successfully managed with laparoscopic surgery. Rapid and accurate diagnosis using appropriate imaging modalities is critical for improving the prognosis of a child-bearing woman with an abdominal pregnancy.

Minimally invasive adenomyomectomy via a laparoscopic-assisted approach compared to a laparoscopic or laparotomic approach.

OBJECTIVE: The present study assessed the safety and benefits of laparoscopic-assisted adenomyomectomy compared to laparoscopic or laparotomic adenomyomectomy. MATERIALS AND METHODS: This study was a retrospective comparative study. A total of 277 patients underwent adenomyomectomy between January 2016 and January 2019 at the Department of Obstetrics and Gynaecology, Ulsan University Hospital, including 25 with laparoscopic-assisted adenomyomectomy, 82 with laparoscopic adenomyomectomy, and 170 with laparotomic adenomyomectomy. Laparoscopic-assisted adenomyomectomy consisted of a laparoscopic uterine artery procedure to reduce blood loss and a minimal incisional for laparotomic adenomyomectomy. An additional laparoscopic surgery was performed for possible pelvic pathology. RESULTS: Data on patient demographics, surgical indications, operative times, estimated blood loss (EBL), short-term complications, and postoperative hospital stays were compared. The laparoscopic-assisted surgery (LAS) and laparotomic groups were comparable in average EBL (208.0 ± 128.8 vs. 193.6 ± 193.0 ml, p = 0.11), weight of removed mass (85.5 ± 71.7 vs. 108.2 ± 91.9 g, p = 0.39), and postoperative hospital days (HDs) (4.5 ± 1.0 vs. 4.7 ± 0.8 days, p = 0.27). These values were lower in the laparoscopic group (EBL 119.5 ± 79.6 ml, mass weight 39.3 ± 25.9 g, HD 3.6 ± 0.8 days). Additional procedures, including myomectomy and combined severe endometriosis surgery, were more frequently performed in the LAS group than the laparotomic group. The mean operating time was longer in the LAS group (179.8 ± 36.6 min) than the other groups (laparoscopy 99.9 ± 40.6 min, p < 0.00; laparotomy 133.0 ± 41.1 min, p < 0.00). The three groups did not differ significantly in transfusion rates, hemoglobin changes, or perioperative complications. However, febrile morbidity was lower in the laparoscopic group than the LAS and laparotomic groups. CONCLUSION: LAS adenomyomectomy allows for maximal debulking of adenomyosis via extracorporeal and intracorporeal procedures while retaining the advantages of the laparoscopic approach. Additional pelvic surgery for benign uterine and adnexal pathology may easily be performed with this approach.

Maternal Bochdalek Hernia during Pregnancy: A Systematic Review of Case Reports.

BACKGROUND: Since the first report of a diaphragmatic hernia from Ambroise Paré's necropsy in 1610, the Bochdalek hernia (BH) of the congenital diaphragmatic hernia (CDH) has been the most common types with high morbidity and mortality in the neonatal period. Due to the nature of the disease, CDH associated with pregnancy is too infrequent to warrant reporting in the literature. Mortality of obstruction or strangulation is mostly due to failure to diagnose symptoms early. DATA SOURCES AND STUDY SELECTION: A systematic literature search of maternal BH during pregnancy was conducted using the electronic databases (PubMed and EMBASE) from January 1941 to December 2020. Because of the rarity of the disease, this review included all primary studies, including case reports or case series that reported at least one case of maternal BH in pregnant. Searches, paper selection, and data extraction were conducted in duplicate. The analysis was performed narratively regardless of the control groups' presence due to their rarity. RESULTS: The search retrieved 3450 papers, 94 of which were deemed eligible and led to a total of 43 cases. Results of treatment showed 16 cases in delayed delivery after hernia surgery, 10 cases in simultaneous delivery with hernia surgery, 3 cases in non-surgical treatment, and 14 cases in hernia surgery after delivery. Of 16 cases with delayed delivery after hernia surgery, 13 (81%) cases had emergency surgery and three (19%) cases had surgery after expectant management. Meanwhile, 10 cases underwent simultaneous delivery with hernia surgery, 6 cases (60%) had emergent surgery, and 4 cases (40%) had delayed hernia surgery after expectant management. 3 cases underwent non-surgical treatment. In this review, the maternal death rate and fetal/neonatal loss rate from maternal BH was 5% (2/43) and 16% (7/43), respectively. The preterm birth rate has been reported in 35% (15/43) of maternal BH, resulting from maternal deaths in 13% (2/15) of cases and 6 fetal loss in 40% (6/15) of cases; 44% (19/43) of cases demonstrated signs of bowel obstruction, ischemia, or perforation of strangulated viscera in the operative field, resulting from maternal deaths in 11% (2/19) of cases and fetal-neonatal loss in 21% (4/19) of cases. CONCLUSION: Early diagnosis and surgical intervention are imperative, as a gangrenous or non-viable bowel resection significantly increases mortality. Therefore, multidisciplinary care should be required in maternal BH during pregnancies that undergo surgically repair, and individualized care allow for optimal results for the mother and fetus.

The Diagnostic Accuracy of Magnetic Resonance Imaging for Maternal Acute Adnexal Torsion during Pregnancy: Single-Institution Clinical Performance Review.

BACKGROUND: For acute adnexal torsion of pregnant women, appropriate treatment based on an accurate diagnosis is especially important for fertility preservation and timely treatment. The 2017 American College of Obstetricians and Gynecologists (ACOG) Committee Opinion No. 723 announced its practice-changing guidelines to ensure that diagnostic magnetic resonance imaging (MRI) conducted during the first trimester and gadolinium exposure at any time during pregnancy are safe for fetal stability. Unfortunately, few studies have been performed to evaluate the usefulness of the diagnostic accuracy of MRI for acute adnexal torsion during pregnancy. OBJECTIVE: We sought to determine the efficacy of diagnostic MRI modality using multiparameter for maternal adnexal torsion during pregnancy. METHODS: From 1 January 2007 to 31 January 2019, 131 pregnant with MRI tests were reviewed. In this retrospective cohort study, 94 women were excluded due to conditions other than an adnexal mass, and 37 were identified through MRI analyses conducted before surgery for suspected adnexal torsion. The primary outcome was the diagnostic accuracy of sonography and MRI, and the secondary outcome was the usefulness of Apparent diffusion coefficient (ADC) values for predicting the severity of hemorrhagic infarction between the medulla and cortex of the torsed ovarian parenchyma. RESULTS: Our study demonstrates that in the diagnosis of adnexal torsion during pregnancy, the sensitivity, specificity, positive predictive value, and negative predictive value are 62.5%, 83.3%, 90.9%, and 45.5% for sonography and 100%, 77.8%, 90.5%, and 100% for MRI. MRI results in surgical-proven adnexal torsion patients revealed unilocular ovarian cysts (36.8% (7/19)), multilocular ovarian cysts (31.6% (6/19)), and near normal-appearing ovaries (31.6% (6/19)). Pathology in adnexal torsion revealed a corpus luteal ovarian cyst (63.2% (12/19)) and underlying adnexal pathology (46.8% (7/19)). Maternal adnexal torsion during pregnancy was more likely to occur in corpus luteal ovarian cysts than in underlying adnexal masses (odds ratio, 2.14; 95% confidence interval (CI), 0.428-10.738). MRI features for adnexal torsion were as follows: tubal wall thickness, 100% (19/19); ovarian stromal (medullary) edema, 100% (19/19); symmetrical or asymmetrical ovarian cystic wall, 100%(19/19); prominent follicles in the ovarian parenchyma periphery, 57.9% (11/19); periadenxal fat stranding, 84.2% (16/19); uterine deviation to the twisted side, 21.1% (4/19); and peritoneal fluid, 42.1% (8/19). The signal intensity of the ADC values of the ovarian medulla and cortex were compared between the cystectomy and detorsion (CD) and salpingo-oophorectomy (SO) groups. The ADC values of the CD and SO groups were 1.81 ± 0.09 × 10-3 mm2/s and 1.91 ± 0.18 × 10-3 mm2/s, respectively (P = 0.209), in the ovarian medulla and 1.37 ± 0.32 × 10-3 mm2/s and 0.96 ± 0.36 × 10-3 mm2/s, respectively (P = 0.022), in the ovarian cortex. The optimal cut-off value of ADC values for predictable total necrosis in the torsed ovarian cortex was ≤ 1.31 × 10-3 mm2/s (area under the curve (AUC) = 0.81; 95% CI 0.611-1.0; P = 0.028). CONCLUSION: Our data showed that maternal adnexal torsion during pregnancy occurred in most corpus luteal cystic ovary cases and some normal-appearing ovary during the 1st and 2nd trimesters of gestation. Therefore, this study is the first study to elaborate on the existence or usefulness of the diagnostic MRI for acute maternal adnexal torsion during pregnancy and to provide a predictive diagnosis of the severity of hemorrhagic infarction for deciding surgical radicality.

Prediction of ovarian aging using ovarian expression of BMP15, GDF9, and C-KIT.

IMPACT STATEMENT: Ovarian aging is becoming a more important issue in terms of fertility preservation and infertility treatment. Serum anti-Mullerian hormone (AMH) level and antral follicle count (AFC) are being practically used as markers of ovarian aging as well as ovarian reserve in human. However, these factors have some drawbacks in assessing ovarian aging and reserve. Therefore, the identification of ovarian expressions of BMP15, GDF9, and C-KIT according to female could be applied as a potent predictor of ovarian aging. This work provides new information on the development of diagnosis and treatment strategy of age-related fertility decline and premature ovarian insufficiency.

Human chorionic gonadotropin-administered natural cycle versus spontaneous ovulatory cycle in patients undergoing two pronuclear zygote frozen-thawed embryo transfer.

OBJECTIVE: To compare human chorionic gonadotropin (HCG)-administered natural cycle with spontaneous ovulatory cycle in patients undergoing frozen-thawed embryo transfer (FTET) in natural cycles. METHODS: In this retrospective cohort study, we analyzed the clinical outcome of a total of 166 consecutive FTET cycles that were performed in either natural cycle controlled by HCG for ovulation triggering (HCG group, n=110) or natural cycle with spontaneous ovulation (control group, n=56) in 166 infertile patients between January 2009 and November 2013. RESULTS: There were no differences in patients' characteristics between the 2 groups. The numbers of oocytes retrieved, mature oocytes, fertilized oocytes, grade I or II embryos and frozen embryos in the previous in vitro fertilization (IVF) cycle in which embryos were frozen were comparable between the HCG and control groups. Significant differences were not also observed between the 2 groups in clinical pregnancy rate (CPR), embryo implantation rate, miscarriage rate, live birth rate and multiple CPR. However, the number of hospital visits for follicular monitoring was significantly fewer in the HCG group than in the control group (P<0.001). CONCLUSION: Our results demonstrated that HCG administration for ovulation triggering in natural cycle reduces the number of hospital visits for follicular monitoring without any detrimental effect on FTET outcome when compared with spontaneous ovulatory cycles in infertile patients undergoing FTET in natural ovulatory cycles.

Prediction of pregnancy complication occurrence using fetal cardiac output assessments made by ultrasonography at 20 to 24 weeks of gestation.

OBJECTIVE: To evaluate the importance of assessment of fetal cardiac output (CO) for the prediction of complications of pregnancy. METHODS: We evaluated 65 fetuses and all of them had a fetal cardiac scan at 20 to 24 weeks of pregnancy. To measure CO, diameters (d) of the left right ventricle outflow tract were measured just above the valves. Each left CO (LCO) and right CO (RCO) was derived using the following equation: CO = velocity time integral × π × d2/4 × heart rate. Pregnancy complications included gestational hypertensive disorders, fetal growth restriction (FGR) and preterm birth (PTB) caused from preterm labor or preterm premature rupture of membrane (PPROM). RESULTS: There were 23 cases with one more pregnancy complication (FGR, 9; gestational hypertensive disorders, 8; PTB caused from PTB or PPROM, 12). The LCO was lower in complication group than in normal group (88±53 vs. 117±48 mL/min, P=0.028). The RCO to the LCO ratio (RCO/LCO) was higher in complication group (2.43±1.69 vs. 1.48±0.81, P=0.001). Regression analysis demonstrated that RCO/LCO was a significant predictor of pregnancy complication; Odds ratio was 7.76 (95% CI, 1.15 to 52.21; P=0.029). The area under the receiver-operating characteristic curve for prediction of pregnancy complications from LCO was 0.71. The diagnostic cut-off value of LCO was 80 mL/min. The area under the receiver-operating characteristic curve from RCO/LCO was 0.68 and cut-off value was 1.41. CONCLUSION: This study demonstrated that pregnancy complications can be suspected based on fetal CO assessments at a GA of 20 to 24 weeks.

Vaginal vault drainage after complicated single-port access laparoscopic-assisted vaginal hysterectomy.

STUDY OBJECTIVE: To evaluate the feasibility and safety of vaginal vault drainage after complicated singleport access laparoscopic-assisted vaginal hysterectomy (SPA-LAVH). DESIGN: Retrospective cohort study. SETTING: Ulsan University Hospital (tertiary teaching hospital), South Korea. PATIENTS: A total of 359 women underwent SPA-LAVH for the following conditions: benign uterine tumor, preinvasive uterine lesion, and microinvasive cervical cancer. INTERVENTIONS: The participants included 124 women with vault drains and 235 women without drains. MEASUREMENTS: Surgical outcomes, perioperative complications and morbidity, postoperative febrile morbidity. RESULTS: There were no differences in background features between drain and no-drain groups. In surgical outcomes, mean uterine weight (364.2 ± 184.9 g vs. 263.7 ± 138.6 g; p < 0.001), operation time (87.4 ± 21.5 min vs. 73.0 ± 17.6 min; p < 0.001), blood loss (225.3 ± 122.2 mL vs. 150.4 ± 95.2 mL; p < 0.001), and hemoglobin decline (1.97 ± 0.96 g/dL vs. 1.42 ± 0.89 g/dL; p < 0.001) were significantly larger for the drain group compared with the no-drain group. However, with regard to postoperative morbidity and complications, there were no group differences in the transfusion rates (6.5% vs. 3.8%; p = 0.300), intraoperative complications (2.4% vs. 1.3%; p = 0.420), perioperative complications (2.4% vs. 0.9%; p = 0.345), and febrile morbidity ≥ 37.5°C (8.9% vs. 11.5%; p = 0.477), although the drain group was more prone to the development of pelvic fluid collection and febrile morbidity than the no-drain group. CONCLUSION: Vaginal vault drainage could be a safe alternative that allows for the management of postoperative morbidity and retains the advantages of minimally invasive surgery after complicated SPA-LAVH.

A live birth after spontaneous complete chorioamniotic membrane separation associated with uterine scar.

Spontaneous complete chorioamniotic membrane separation (CMS) without invasive fetal procedure is extremely rare and associated with adverse perinatal outcomes. A woman with complete CMS which was detected at the 21 weeks' gestation. She did not take any fetal invasive procedures before the diagnosis. At 27 weeks' gestation, an emergency Caesarean section was performed because of fetal distress. The defect of the uterine muscle was detected on the fundus. The baby has grown well without any morbidity. This is the first reported case of complete CMS relative to uterine scar. And we suggest that the pregnancy can be maintained successfully if there is no fetal abnormality when complete CMS is detected on ultrasound.

Transient occlusion of uterine arteries in laparoscopic uterine surgery.

BACKGROUND AND OBJECTIVES: This study was conducted to determine the feasibility and effectiveness of transient occlusion of the uterine arteries (TOUA) during laparoscopic surgery for benign uterine tumors, with preservation of fertility. METHODS: Patients with uterine myoma or adenomyoma underwent laparoscopic uterine surgery, with or without TOUA, performed by a single surgeon (Y.-S.K.). Surgical outcomes included operative time; occurrence of intraoperative injury of blood vessels, nerves, and pelvic organs; and intraoperative blood loss. RESULTS: Of the 168 surgical patients included in this study, 144 were enrolled consecutively during the study period, and 24 had undergone adenomectomy before the study period. A total of 104 women (70 with myoma; 34 with adenomyoma) seeking uterine preservation underwent laparoscopic surgery with TOUA for benign uterine tumors. Sixty-four women (40 with myoma; 24 with adenomyoma) underwent surgery without TOUA. The mean total surgical time of the TOUA groups was 74.85 minutes for uterine myoma and 84.09 minutes for uterine adenomyoma. The mean estimated blood loss during laparoscopic myomectomy and adenomyomectomy was less in the TOUA groups than in the non-TOUA groups (109 vs. 203.4 mL in myomectomy, P < .05; 148.1 vs. 158.9 mL in adenomyomectomy; P < .05). Time to perform TOUA was 13.9 minutes in laparoscopic myomectomy and 7.33 minutes in laparoscopic adenomyomectomy. The hospital stay of the TOUA groups was 3.32 days for uterine myoma and 3.82 days for uterine adenomyoma. No intraoperative conversion to laparotomy was necessary, and no major complications occurred during any of the procedures. CONCLUSION: Laparoscopic uterine surgery with TOUA could be a safe and effective surgical method for women with symptomatic benign uterine tumors who wish to preserve fertility.

Conservative adenomyomectomy with transient occlusion of uterine arteries for diffuse uterine adenomyosis.

AIM: This study aimed to determine the feasibility and safety of adenomyomectomy with transient occlusion of uterine arteries (TOUA) in patients with symptomatic diffuse uterine adenomyosis. MATERIAL AND METHODS: Twenty-six patients with symptomatic diffuse uterine adenomyosis underwent adenomyomectomy with TOUA by a single surgeon at Ulsan University Hospital between May 2011 and September 2012. Surgical outcomes included operative time, intraoperative injury to blood vessels, nerves, and pelvic organs and operative blood loss. We assessed the degree of improvement in dysmenorrhea and menorrhagia at the 4-month follow-up after completion of adjuvant gonadotrophin-releasing hormone agonist. RESULTS: The mean age of patients was 37.73 years (range, 27-49 years). The mean total surgical time was 95.0 min (range, 60-145 min; SD, 34.49). The mean estimated blood loss was 191.54 mL (range, 80-400 mL; SD, 110.91) and there were no cases of injury to the uterine arteries or pelvic nerves. The mean time of TOUA was 9.79 min (range, 6-16 min; SD, 2.74). The mean duration of hospital stay was 5.65 days (range, 4-7 days; SD, 0.85). There were no major complications requiring reoperation or readministration during the mean follow-up period of 13.5 months. At the 7-month follow-up after adenomyomectomy with TOUA, complete remission of dysmenorrhea and menorrhagia was observed in 94.4% and 100% of patients, respectively. CONCLUSIONS: Adenomyomectomy with TOUA could be a safe and effective surgical method in women with symptomatic diffuse uterine adenomyosis to preserve fertility.

Subclinical hypothyroidism diagnosed by thyrotropin-releasing hormone stimulation test in infertile women with basal thyroid-stimulating hormone levels of 2.5 to 5.0 mIU/L.

OBJECTIVE: To investigate the prevalence of subclinical hypothyroidism (SH) diagnosed by thyrotropin-releasing hormone (TRH) stimulating test in infertile women with basal thyroid-stimulating hormone (TSH) levels of 2.5 to 5.0 mIU/L. METHODS: This study was performed in 39 infertile women with ovulatory disorders (group 1) and 27 infertile women with male infertility only (group 2, controls) who had basal serum TSH levels of 2.5 to 5.0 mIU/L and a TRH stimulating test. Serum TSH levels were measured before TRH injection (TSH0) and also measured at 20 minutes (TSH1) and 40 minutes (TSH2) following intravenous injection of 400 µg TRH. Exaggerated TSH response above 30 mIU/L following TRH injection was diagnosed as SH. Group 1 was composed of poor responders (subgroup A), patients with polycystic ovary syndrome (subgroup B) and patients with WHO group II anovulation except poor responder or polycystic ovary syndrome (subgroup C). RESULTS: The prevalence of SH was significantly higher in group 1 of 46.2% (18/39) compared with 7.4% (2/27) in group 2 (P=0.001). TSH0, TSH1, and TSH2 levels were significantly higher in group 1 than the corresponding values in group 2 (P<0.001, P<0.001, P<0.001). In group 1, TSH1 and TSH2 levels were significantly lower in subgroup C compared with those in subgroup A and B (P=0.008, P=0.006, respectively). CONCLUSION: TRH stimulation test had better be performed in infertile women with ovulatory disorders who have TSH levels between 2.5 and 5.0 mIU/L for early detection and appropriate treatment of SH.

Combined administration of gonadotropin-releasing hormone agonist with human chorionic gonadotropin for final oocyte maturation in GnRH antagonist cycles for in vitro fertilization.

OBJECTIVE: To evaluate the effects of combined administration of gonadotropin-releasing hormone (GnRH) agonist with human chorionic gonadotropin (hCG)for final oocyte maturation in GnRH antagonist cycles for in vitro fertilization (IVF). STUDY DESIGN: A total of 120 infertile women undergoing GnRH antagonist multiple-dose protocol for controlled ovarian stimulation were recruited and randomized into 2 groups: a study group (n=60) and a control group (n=60). For the study group, both GnRH agonist and recombinant hCG (rhCG) were injected concomitantly for final oocyte maturation when 1 or more follicles reached a mean diameter of 18 mm. For the control group, rhCG alone was administered for final oocyte maturation. RESULTS: There were no significant differences in patient characteristics. The 2 groups were also similar with respect to the number of oocytes retrieved, fertilized oocytes and good-quality embryos. Embryo implantation rate (24.7% vs. 14.9%), clinical pregnancy rate per cycle (53.3% vs. 33.3%), and live birth rate (50.0% vs. 30.0%) were significantly higher in the study group than in the control group (p = 0.006, p = 0.027, and p = 0.025, respectively). CONCLUSION: Combined administration of GnRH agonist with rhCG may be beneficial in improving endometrial receptivity and pregnancy rate in GnRH antagonist cycles for IVF.

Ovarian Features after 2 Weeks, 3 Weeks and 4 Weeks Transdermal Testosterone Gel Treatment and Their Associated Effect on IVF Outcomes in Poor Responders.

This study was performed to investigate the effect of of transdermal testosterone gel (TTG) on controlled ovarian stimulation (COS) and IVF outcomes and ovarian morphology according to pretreatment duration in poor responders. A total of 120 women were recruited for this pilot study. They were randomized into control, 2 weeks, 3 weeks or 4 weeks TTG treatment groups. For three TTG treatment groups, 12.5 mg TTG was applied daily for 2 weeks, 3 weeks or 4 weeks in preceding period of study stimulation cycle. After 3 weeks of TTG pretreatment, significant increase of antral follicle count (AFC) and significant decreases of mean follicular diameter (MFD) and resistance index (RI) value of ovarian stromal artery were observed (p=0.026, p<0.001, p<0.01, respectively). The total dose of rhFSH administered for COS significantly decreased after 3 and 4 weeks TTG treatment both compared with control group (p<0.001, p<0.001). The numbers of oocytes retrieved and mature oocytes were significanty higher in 3 and 4 weeks TTG treatment groups than control group (p<0.001, p<0.001 in the number of oocytes retrieved; p<0.001, p<0.001 in the number of mature oocytes). The clinical pregnancy rate and live birth rate were increased only in 4 weeks TTG treatment group compared with control group (p=0.030 and p=0.042, respectively). These data demonstrated that TTG pretreatment for 3 to 4 weeks increases AFC and ovarian stromal blood flow, thereby potentially improving the ovarian response to COS and IVF outcome in poor responders undergoing IVF/ICSI.
