RESUMO
BACKGROUND/PURPOSE: Mesh-augmented vaginal surgery for treatment of pelvic organ prolapse (POP) does not meet patients' needs. This study aims to test the hypothesis that fascia tissue engineering using adipose-derived stem cells (ADSCs) might be a potential therapeutic strategy for reconstructing the pelvic floor. METHODS: Human ADSCs were isolated, differentiated, and characterized in vitro. Both ADSCs and fibroblastic-differentiated ADSCs were used to fabricate tissue-engineered fascia equivalents, which were then transplanted under the back skin of experimental nude mice. RESULTS: ADSCs prepared in our laboratory were characterized as a group of mesenchymal stem cells. In vitro fibroblastic differentiation of ADSCs showed significantly increased gene expression of cellular collagen type I and elastin (p < 0.05) concomitantly with morphological changes. By contrast, ADSCs cultured in control medium did not demonstrate these changes. Both of the engrafted fascia equivalents could be traced up to 12 weeks after transplantation in the subsequent animal study. Furthermore, the histological outcomes differed with a thin (111.0 ± 19.8 µm) lamellar connective tissue or a thick (414.3 ± 114.9 µm) adhesive fibrous tissue formation between the transplantation of ADSCs and fibroblastic-differentiated ADSCs, respectively. Nonetheless, the implantation of a scaffold without cell seeding (the control group) resulted in a thin (102.0 ± 17.1 µm) fibrotic band and tissue contracture. CONCLUSION: Our results suggest the ADSC-seeded implant is better than the implant alone in enhancing tissue regeneration after transplantation. ADSCs with or without fibroblastic differentiation might have a potential but different role in fascia tissue engineering to repair POP in the future.

OBJECTIVE: Oncofetal protein insulin-like growth factor II mRNA-binding protein 1 (IMP1) regulates cellular proliferation and migration. Expression of IMP1 is limited to a few adult human tissues. However, it commonly expresses in a variety of cancers. Our objective was to study the regulatory mechanism of IMP1 on the cellular functions of choriocarcinoma (CC) JAR cells. METHODS: IMP1 protein levels were measured in CC tissues via immunohistochemistry. Specific siRNAs were used to down-regulate gene expressions. The abilities of migration and invasion were estimated by wound-healing and Matrigel chamber assays. The profile of IMP1-binding genes was investigated with an Agilent microarray. RT-qPCR, RNA immunoprecipitation, and IMP1 rescue experiments were performed to confirm the association between IMP1 and its binding genes. Gene expression was further analyzed by using RT-PCR and Western blotting. RESULTS: Strong IMP1 expressions were frequently detected in CC tissues. Knockdown of IMP1 expression in JAR cells inhibited cell migration and invasion, but did not affect cellular proliferation and morphology. Microarray and RNA-immunoprecipitation results revealed several candidate genes regulated by IMP1. Among them, ribosomal protein S6 kinase (RSK2) and protein phosphatase methylesterase 1 (PPME1) were confirmed to be down-regulated in IMP1-depleted JAR cells. Re-expression of IMP1 into the cells restored the expressions of RSK2 and PPME1. Furthermore, the depletion of RSK2 or PPME1 decreased the migration and invasion of JAR cells. CONCLUSION: Our results suggest that IMP1 plays an essential role in the regulation of migration and invasion of human CC cells, possibly through the novel effectors RSK2 and PPME1.

BACKGROUND: LOX-1, a lectin-like receptor on endothelial cells, facilitates the uptake of oxidized low-density lipoprotein (oxLDL). Expression of LOX-1 is involved in the pathobiological effects of oxLDL in endothelial cells, including reactive oxygen species (ROS) generation, suppression of endothelial nitric oxide synthase (eNOS) activity, and leukocytic adhesion. Moderate consumption of phenolic-enriched food may have a protective effect against the development of atherosclerosis via the antioxidant capacity of phenolic compounds at the endothelial level. In this study, we determined whether ellagic acid, a polyphenolic compound widely distributed in fruits and nuts, protects against oxLDL-induced endothelial dysfunction by modulating the LOX-1-mediated signaling pathway. METHODS: Human umbilical vein endothelial cells (HUVECs) were pretreated with ellagic acid at doses of 5, 10, 15, and 20 µM for 2 hours and then incubated with oxLDL (150 µg/mL) for an additional 24 hours. RESULTS: LOX-1 protein expression was markedly lower after exposure to oxLDL in HUVECs pretreated with ellagic acid or diphenyleneiodonium, a well-known inhibitor of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase, than in HUVECs exposed to oxLDL alone, suggesting that ellagic acid deactivates NADPH oxidase. We also found that oxLDL activated the membrane assembly of p47phox, Rac1, gp91 and p22phox, and the subsequent induction of ROS generation; however, ROS generation was markedly suppressed in cells pretreated with ellagic acid or anti-LOX-1 monoclonal antibody. In addition, oxLDL down-regulated eNOS and up-regulated inducible NO synthase (iNOS), thereby augmenting the formation of NO and protein nitrosylation. Furthermore, oxLDL induced the phosphorylation of p38 mitogen-activated protein kinase, activated the NF-κB-mediated inflammatory signaling molecules interleukin-(IL) 6 and IL-8 and the adhesion molecules intercellular adhesion molecule-1, vascular cell adhesion molecule-1, and E-selectin, and stimulated the adherence of THP-1 (a human acute monocytic leukemia cell line) to HUVECs. Pretreatment with ellagic acid, however, exerted significant cytoprotective effects in all events. CONCLUSION: Findings from this study may provide insight into a possible molecular mechanism by which ellagic acid inhibits LOX-1-induced endothelial dysfunction. Our data indicate that ellagic acid exerts its protective effects by inhibiting NADPH oxidase-induced overproduction of superoxide, suppressing the release of NO by down-regulating iNOS, enhancing cellular antioxidant defenses, and attenuating oxLDL-induced LOX-1 up-regulation and eNOS down-regulation.

OBJECTIVE: We describe our experience with serial uterine artery embolization (UAE) combined with standard weekly methotrexate and a eight-day methotrexate/folinic acid (MTX/FA) treatment regimen in the management of placenta accreta spectrum (PAS) disorder at 7 weeks of gestation. CASE REPORT: A 38-year-old woman, gravida 2 para 0, with a history of myomectomy, was referred for ultrasound (US) evaluation due to suspected cervico-isthmic pregnancy. Transvaginal US image showed a viable embryo with a disproportionately bigger placenta encircling the fetus and completely covering the internal os of the cervix at 7 weeks of gestation. Color Doppler imaging revealed diffuse intraplacental and periplacental vascularity. Patient chose to terminate the pregnancy but attempted to preserve the uterus for future fertility following counseling. Serial UAE procedures were performed using Gelfoam and metallic microcoils. Two courses of a standard weekly MTX and a eight-day MTX/FA treatment regimen were administered to accelerate placental regression. The beta-hCG gradually decreased to a normal level, and an ultimate resolution of the PAS disorder was observed at 110 days after treatment. CONCLUSION: Early diagnosis of the PAS disorder could result in better obstetric outcome through earlier intervention using serial UAE combined with standard weekly and a eight day MTX//FA regimen in the first trimester of pregnancy.

OBJECTIVE: We describe herein our experience of employing a hysterectomy and prophylactic internal iliac artery balloon occlusion (IIABO) strategy for the management of recurrent severe placenta increta at 8 weeks in a twin pregnancy following uterus-conserving surgery for prior placenta accreta spectrum (PAS) disorder. CASE REPORT: A 40-year-old woman with a history of uterus-conserving surgery for PAS disorder underwent transvaginal ultrasound evaluation at 8 weeks of pregnancy, which showed a dichorionic/diamniotic pregnancy with viable embryos of a crown-rump length of 1.65 cm and 2.03 cm, respectively. Many irregularly-shaped grade 3+ lacunae were observed, and color Doppler imaging revealed diffuse intraplacental and perihypervascularity. A total abdominal hysterectomy was performed at 10 weeks, with an estimated blood loss of 1275 mL. Placenta increta was confirmed by histopathologic examination. CONCLUSION: The high rate of recurrence of PAS disorder in a subsequent pregnancy should be discussed following an antenatal diagnosis of PAS disorder with patients who may be considering uterine conservation in order to retain the option of a future pregnancy.

Placenta previa increta/percreta (I/P) is a severe form of invasive placentation associated with massive peripartum hemorrhage, which often requires Cesarean hysterectomy. The pathogenesis of invasive placentation is multidimensional, involving decidual deficiency, endomyometrial damage and excessively deep trophoblast invasion into the uterus. In this study, annealing control primer-polymerase chain reaction (ACP-PCR) was used to identify differentially expressed genes, which may impair placentation resulting in placenta previa I/P. Placental tissues from I/P and non-increta/percreta (non-I/P) sites were concomitantly collected from patients undergoing Cesarean hysterectomy. After ACP-PCR experiments (three patients), the differentially expressed bands, consistently showing up- or down-regulated trends between each of the I/P and non-I/P tissue pairs, were cloned and sequenced. Human non-protein coding metastasis associated lung adenocarcinoma transcript 1 (MALAT-1) gene was identified. Real-time quantitative PCR (10 patients) confirmed significant overexpression of MALAT-1 in I/P samples (P = 0.005). To investigate the role of MALAT-1 gene in the regulation of trophoblast cell invasion, targeting of MALAT-1 mRNA expression with short interfering RNA (siRNA) in trophoblast-like BeWo, JAR and JEG-3 choriocarcinoma cells was performed. The invasion ability of these cells was significantly suppressed after siRNA silencing (P < 0.001), and this was not correlated with abnormal MMP-2 and MMP-9 enzyme activities. Our results suggest that MALAT-1 expression in placenta previa I/P is increased and its down-regulation inhibits trophoblast-like cell invasion in vitro. MALAT-1 might be involved in regulating trophoblast invasion during the development of advanced invasive placentation.

BACKGROUND: To evaluate the clinical association of extrastructurally abnormal chromosomes (ESACs) with pregnancy outcome based on the cytogenetic characteristics of the ESACs. METHODS: We retrospectively reviewed 12 ESAC cases identified from 12,991 cases who received genetic amniocentesis between January 1983 and March 2008. Prenatal ultrasound findings, characteristics of ESACs (karyotypes, special features, origin, inheritance) and pregnancy outcomes were recorded. RESULTS: The prenatal prevalence of ESACs was 0.092% (12/12,991). Of the 12 ESAC cases, all were de novo. Seven (58.3%) originated from nonacrocentric chromosomes and the other 5 (41.7%) were from acrocentric chromosomes, with 3 originating from chromosome 15. Six of the 12 cases (50%) were large ESACs; however, the other 6 (50%) were medium to small ESACs. All acrocentric ESACs contained dicentric and bisatellite characteristics. Using FISH and SKY techniques, the origins of 2 cases (patients 10 and 12) were clearly identified to be from chromosomes 15 and 10, respectively. Five of the 12 ESAC cases (41.7%) had congenital anomalies found by prenatal ultrasound. All were nonacrocentric in origin that were medium (1/5) to large (4/5) in size. After prenatal genetic counseling, 8 of the 12 (66.7%) couples opted to terminate the pregnancy. The other 4 (33.3%) continued the pregnancy and their babies were delivered at term normally and were followed-up, with normal development ranging from 2 to 17 years. CONCLUSION: With sophisticated cytogenetic characterization and ultrasound examination, it is possible to precisely categorize most fetuses with ESACs as being either at high risk of abnormality or at a relatively low risk.

A 32-year-old primigravida was referred to our hospital at 36 weeks of gestation with a fetal pelvic mass. Ultrasonography showed the fluid-filled area to be a 9 x 4 x 5-cm pear-shaped retrovesical mass with a funnel-shaped blind pouch at the distal end of the fetal vagina. Marked left hydronephrosis resulting from mass compression was also detected. Fetal magnetic resonance imaging further defined a pelvic lesion extending cephalically into the abdomen and caudally into the vagina. Membranal protrusion of the introitus was clearly identified. Therefore, the diagnosis of congenital imperforate hymen with hydrocolpos was established. At 38 weeks of gestation, a 2,966-g female infant was delivered vaginally with good Apgar scores. Physical examination of the neonate revealed a bulging membrane covering the vaginal opening. The presence of syndromic disorders (McKusick-Kaufman, Ellis-van Creveld or Bardet-Biedl syndromes), genitourinary and anorectal anomalies were excluded. The karyotype was 46,XX. A hymenotomy was performed on the second day of life. The infant recovered fully after hymenotomy.

A precise prenatal diagnosis of hemangioma may be uncertain although a variety of the antenatal appearances on 2-dimensional sonography have been reported. A 27-year-old primigravida was referred at 32 weeks of gestation for evaluation of a fetal nuchal mass. Two-dimensional sonography showed an extracranial mixed echogenic mass (65 x 54 x 59 mm) occupying the posterior neck. Color Doppler imaging revealed intense hypervascularization. Three-dimensional (3D) and 4-dimensional (4D) sonography showed that the mass was lobulated, with a lumpy internal structure. Nuchal hemangioma was further confirmed by clinical examination and postnatal magnetic resonance imaging. The tumor began to regress in size when the infant was 7 months old. Prenatal 3D/4D ultrasound techniques could be considered as complementary diagnostic tools for such a tumor. They have the advantages of providing accurate and inexpensive virtual reality images through more realistic interactions with the virtualized in utero condition.

OBJECTIVE: The purpose of this study was to describe our preliminary experience of the efficacy and safety of a conservative strategy for abnormally invasive placenta. MATERIALS AND METHODS: A retrospective review of eight pregnant women with abnormally invasive placenta (one with placenta previa accrete, three with placenta previa increta, and four with previa percreta) was performed. The diagnosis was made by prenatal ultrasonography, and was confirmed by operative and histopathological findings. Patients who desired future fertility or who had extensive diseases were selected as candidates after panel meeting. Conservative management after obtaining informed consent was defined by a primary cesarean delivery before 35 weeks of gestation with the abnormally adherent placenta left in situ, partially or totally. The primary outcome was successful uterine preservation. The secondary outcome was severe maternal morbidity including sepsis, coagulopathy, immediate or delayed hemorrhage bladder injury, and fistula. RESULTS: Among the eight patients, the mean age was 34 ± 3 years (range, 30-40 years). All women had risk factors, such as placental previa, previous cesarean delivery and/or dilation & curettage, for abnormally invasive placenta. Seven women underwent planned cesarean delivery at the mean gestation age of 34 weeks (range, 31-37 weeks). One woman received hysterotomy at 18 weeks. In our series, the uterus was preserved in only two cases (25%), one who received hysterotomy at a relatively young gestational age and another who had mild disease. Mean maternal blood loss during primary cesarean delivery was 528 ± 499 ml (range, 100 ml-1,500 ml). Severe maternal morbidity was recorded in seven out of eight patients (87.5%). CONCLUSION: In this small series, we observed a low successful uterine preservation rate and a high maternal complication rate. We recommend that primary cesarean hysterectomy should be used as the treatment of choice for mild to severe abnormally invasive placenta. Conservative management should be reserved for women with a strong fertility desire and women with extensive disease that precludes primary hysterectomy due to surgical difficulty.

OBJECTIVE: There are increasing concerns regarding the adverse effects associated with control ovarian hyperstimulation (COH) in both endometrial and uterine environments. With the "segmentation treatment policy" of assisted reproductive techniques (ART), endometrial problems may be obviated through embryo cryopreservation. However, it remains unclear if the "freeze-all policy" offers a better outcome when compared with fresh embryo transfer (ET). To clarify this, we compared the cumulative live birth rates (CLBRs) between these two patient populations. MATERIALS AND METHODS: This is a retrospective study on 853 patients undergoing ovarian stimulation and ART (including IVF/ICSI) during the period from January 2012 to June 2014 in Taichung Veterans General Hospital, Taiwan, ROC. We followed up with these patients through to November 2016. Patients whose embryos were not completely transferred back were excluded. The study group ('freeze-all') included 84 patients whose cycles were performed initially without fresh ET, but were later given frozen-thawed ET. The control group ('fresh ET') had 625 patients whose cycles were performed with fresh ET, followed by frozen-thawed ET. Basic parameters and CLBRs were statistically compared between these two groups. RESULTS: The CLBRs in the study group were significantly higher than those in the control group (64.3% vs. 45.8%, p = 0.001). Subgroup analysis revealed that when the number of oocyte pick up (OPU) is between 4 and 15, the CLBRs in the study group were significantly better (58.3% vs. 40.9%, p = 0.042). For those with OPU <4 or OPU >15 the CLBRs were similar in these two groups (OPU < 4: study vs. control 23.1% vs. 18.8% respectively, p = 0.713; OPU>15: study vs. control 85.7% vs. 80.8% respectively, p = 0.625) CONCLUSION: The Freeze-all policy improved the ART outcome for normal responders.

OBJECTIVE: To study clinical factors predicting the absence of endocervical/transformation zone (EC/TZ) components of conventional cervical Papanicolaou (Pap) smears. MATERIALS AND METHODS: The medical charts of patients who received Pap smears between March 2006 and August 2006 in the hospital were reviewed. The results of their Pap smears were retrieved while their demographic and clinical information were obtained from the medical charts. After excluding 378 cases with incomplete demographic data and 1397 cases with a history of pelvic irradiation, pelvic malignancy, and hysterectomy, 5662 cases were enrolled for data analysis. The relationship between clinical parameters and the absence of EC/TZ component was analyzed by Pearson Chi-square tests with Yates continuity correction and binary logistic regression tests. RESULTS: The incidence of satisfactory but absence of EC/TZ component was 8.7% (491/5662). Pregnancy increased the absence of EC/TZ component [odds ratio (OR}: 2.84, 95% confidence interval (CI): 2.14-3.77, p<0.0001]. Postpartum status and endocervical polyps decreased incidence (OR: 0.61, 95% CI: 0.38-0.98, p = 0.043 and OR: 0.33, 95% CI: 0.25-0.44, p<0.0001, respectively). CONCLUSIONS: Pregnancy is the only clinical factor associated with increased incidence of absence of EC/TZ cells. For these pregnant women undergoing a Pap smear, a more effective strategy may be needed to get a satisfactory smear with adequate EC/TZ components.

OBJECTIVES: The purpose of this study was to investigate the efficacy and safety of temporary prophylactic intravascular balloon occlusion of the common iliac arteries (CIA) before planned cesarean hysterectomy for controlling operative blood loss in abnormal placentation. MATERIALS AND METHODS: A retrospective study of 13 pregnant women at risk for placenta accreta identified using sequential obstetric ultrasonography and magnetic resonance imaging from January 2007 to December 2009 was performed. Temporary prophylactic intravascular balloon catheterization of the bilateral CIA before cesarean hysterectomy was performed by interventional radiologists. The maximum duration of occlusion time of CIA must not exceed 60 minutes. The primary outcome for this study included estimated blood loss and secondary outcomes included the development of thromboembolism, disseminated intravascular coagulation and surgical complications. RESULTS: Among these 13 patients, the mean age of the patients was 32.8 ± 0.7 years (range 29-37 years). The mean gestational age at cesarean hysterectomy was 32.2 ± 0.9 weeks (range 28-36 weeks), and the mean intraoperative blood loss was 1902.3 ± 578.8 mL (range 500-8000 mL). Operative bleeding was controlled by conservative treatment without additional surgery in two cases. Importantly, two patients (15.8%) had severe complications possibly related to the interventional procedure. One patient was noted to have a popliteal artery thrombosis. A second patient had an external iliac artery thrombosis with 80-90% occlusion. Both patients required antithrombotic treatment without sequelae. CONCLUSION: With limited experience in this small series, we observed a statistically significant reduction in operative blood loss after the use of temporary prophylactic balloon occlusion of the CIA technique compared with historical controls of similar demographic characteristics previously published (1902.3 ± 578.8 mL, range 500-8000 mL vs. 4445.7 ± 996.48 mL, range 1040-15,000 mL, p = 0.0402). Additionally, two patients had arterial thrombosis. These preliminary findings are based on a small number of patients, and therefore further investigation is needed to determine the effectiveness and safety of this new technique.

OBJECTIVE: In 1991, researchers reported that a modest preovulatory increase in serum progesterone levels is associated with lower pregnancy rates and higher incidence of pregnancy loss in in vitro fertilization (IVF). We wonder whether embryo transfer (ET) in assisted reproductive technology (ART) cycles in patients with premature progesterone rise (PPR) have a negative impact on the clinical pregnancy rates (CPRs) and/or live birth rates (LBRs) in our series. Consequently, will blastocyst transfer reverse the negative impact? MATERIALS AND METHODS: This noninterventional, retrospective, observational tertiary center study was conducted between January 2010 and December 2012. All fresh ET cycles with serum progesterone levels measured (n = 599) on the day of hCG administration were analyzed. RESULTS: Sera lutenizing hormone (LH), E2, and progesterone (P) were measured and analyzed. The CPRs of cycles in patients with p ≤ 1.5 ng/mL (low) versus those with p > 1.5 ng/mL (high) were 37.04% versus 41.03% [odds ratio (OR) = 1.18, 95% confidence interval (CI): 0.728-1.920; p = 0.50). The LBRs of cycles in patients with low progesterone level versus those with PPR were 30.52% versus 34.62% (OR = 1.21, 95% CI: 0.729-1.992; p = 0.47). No statistically significant association was detected. We further analyzed the outcomes according to different stages of ET and found that blastocyst (D5) ET significantly increase the LBRs as compared with cleavage stage (D2/D3) ET in the PPR group (44.44% versus 21.43%; p = 0.043). CONCLUSION: PPR did not significantly compromise the clinical outcomes in this series. However, shifting to blastocyst transfer probably could increase the live birth in cycles with PPR.

BACKGROUND: Prenatal ultrasound scans reveal variable features of fetal meconium peritonitis. For better understanding of the natural history and postnatal prognosis of meconium peritonitis, we clarified the significance of ultrasound findings in the outcomes of fetuses with meconium peritonitis. METHODS: Between 1991 and 2001, fetuses who underwent evaluation for meconium peritonitis were retrospectively analyzed. The diagnosis was made by intra-abdominal calcifications, meconium pseudocyst, or meconium ascites, which were postnatally confirmed by the operative findings and/or abdominal plain films. According to the final ultrasound findings before labor, patients were classified into 3 groups: type I, large meconium ascites; type II, a large pseudocyst; type III, intra-abdominal calcifications, small meconium ascites and/or a shrinking pseudocyst. RESULTS: Nineteen fetuses (6 boys and 13 girls) were collected. Mean gestational age at diagnosis was 29.1 +/- 5.3 weeks and mean follow-up before delivery was 7.5 +/- 6.2 weeks. Mean gestational age at birth was 36.8 +/- 6.2 weeks. Six fetuses (31.5%) were delivered before 37 weeks of gestation. Type I was found in 5 (26.3%), type II in 3 (15.8%), and type III in 11 (57.9%). Intra-abdominal calcifications were identified in 15 cases (78.9%), polyhydramnios in 4 (21.1%), and oligohydramnios in 3 (15.8%). Cardiopulmonary resuscitation at birth was required in 2 cases (type I). Twelve cases (63.2 %) were spontaneous perforations. Of 7 other cases (36.8%) studied, 6 had intestinal atresia and 1 had associated defects resulting in bowel perforation. Postnatal follow-up revealed all but 2 (died of sepsis and prematurity, respectively) doing well. CONCLUSIONS: Our results indicate that detailed fetal ultrasound scans are crucial for providing a prenatal diagnosis and proper perinatal management of meconium peritonitis. From the viewpoints of our study, proper prenatal counseling and risk evaluation should be offered to the parents of the fetuses with meconium peritonitis.

OBJECTIVE: Prosima (Ethicon, Somerville, NJ, USA) is a novel procedure for treating pelvic organ prolapse (POP) that uses nonanchored vaginal mesh. However, nonfixation of the mesh may limit effectiveness. The aim of this study was to evaluate the safety, efficacy, and limitations of this procedure. MATERIALS AND METHODS: From January 2011 through to December 2011, 52 patients with symptomatic POP ≥ Stage 2 undergoing the Prosima procedure at a tertiary hospital were enrolled consecutively in this prospective study. A Data and Safety Monitoring Plan (DSMP) was developed to assess the results. RESULTS: Fifty of the 52 patients (96%) attended the 3-6-month postoperative assessment. Symptom and quality-of-life scores were found to have improved significantly after surgery (p < 0.05). Forty-two patients (84%) underwent successful treatment for POP (Stage 0-1). The other eight patients (16%) were found to have recurrent Stage 2 anterior vaginal wall prolapse, although most of them (5/8) were asymptomatic. The highest morbidity, namely vaginal mesh exposure, occurred in four patients (8%) and was managed as a minor issue. Statistical analysis showed that anatomic recurrence was significantly (p < 0.05) associated with a "preoperative Ba ≥ +4 cm" (odds ratio = 20.57), "conservation of the prolapsed uterus" (odds ratio = 10.56) and "use of a concomitant midurethral sling" (odds ratio = 0.076). CONCLUSION: Prosima seems to have limitations when used to manage severe anterior vaginal wall prolapse and concomitant surgery may further affect its effectiveness. The information obtained from this study's DSMP will contribute to developing a strategy to improve the use of nonanchored vaginal mesh for POP repair.

BACKGROUND: The role of midluteal phase gonadotropin-releasing hormone (GnRH) agonist had been an issue of debate. The aim of this retrospective study was to evaluate the effect of a mid-luteal phase GnRH agonist as an additional luteal phase support (LPS) in patients receiving intracytoplasmic sperm injection (ICSI). Additionally, we elucidate which subgroup would gain the most benefit from GnRH agonist as LPS. METHODS: The medical records were retrieved from January 2009 to January 2012 and a total of 348 patients receiving ICSI were included in this retrospective study. Among them, 240 patients met the inclusion criteria of patients aged ≤ 38 years, previous assisted reproductive technology (ART) cycles ≤ 2. There were 147 patients in the decapeptyl group who received GnRH agonist decapeptyl 6 days after ICSI as additional LPS and 93 patients in the control group. Subgroupings were done according to advanced age, the number of previous ART cycles, high basal follicle-stimulating hormone (FSH) level, and patients who had fewer mature oocytes retrieved. Live birth rates, clinical pregnancy rate (CPR), and implantation rate were the primary outcomes. RESULTS: LPS with decapeptyl led to a higher implantation rate (24.5% vs. 17.0%, p = 0.023), a higher CPR (49.0%, n = 72 vs. 33.3%, n = 31, p = 0.023) and a higher live birth rate (41.5%, n = 61 vs. 28.0%, n = 26, p = 0.039). In the subgroup analysis, decapeptyl improved the CPR of those patients with basal FSH >8 mIU/mL (50.0%, n = 15 vs. 8.3%, n = 1, p = 0.031) and also improved CPR (42.3%, n = 11 vs. 0%, n = 0, p = 0.017) and live birth rate (30.8%, n = 8 vs. 0%, n = 0, p = 0.035) of patients whose number of mature oocytes was three or fewer. CONCLUSION: This study demonstrated that administration of decapeptyl as additional luteal support can enhance ICSI clinical outcomes. Those patients with higher basal FSH level or fewer number of mature oocytes may obtain particularly significant benefit.

OBJECTIVE: Use of vaginal meshes for treatment of pelvic organ prolapse (POP) remains controversial. A trend toward abdominal approaches and the development of new meshes has been noted. We compared the 1-year results of two different approaches using new lightweight meshes. MATERIALS AND METHODS: Sixty-nine (95.8%) of 72 women with POP Stage ≥ 2, who underwent laparoscopic sacrocolpopexy (LSC) (n = 39) or a total vaginal mesh (TVM) procedure (n = 30) using lightweight polypropylene meshes, were studied. Baseline and follow-up assessments included a pelvic examination and a composite condition-specific questionnaire. A detailed comparison of 1-year outcomes was made. Data were analyzed using appropriate statistical methods. RESULTS: Compared to the TVM group, the LSC group was characterized by a younger age (53.7 years vs. 64.1 years, p < 0.001) and a longer operating time (264 minutes vs. 177.6 minutes, p < 0.001). Objective anatomic success (POP Stage ≤ 1) rates were similar between groups after statistical adjustment, i.e., 84.6% (33/39) and 86.7% (26/30) after LSC and TVM (p = 0.94), respectively. However, the dominant recurrence sites were different with anterior (n = 6) most frequent after LSC and apical (n = 4) most frequent after TVM. Reoperations were needed for the four (13.3%) apical recurrences in the TVM group. No serious complications were noted. We found "cystocele as the dominant prolapse" (p = 0.016; odds ratio = 6.94) and "suspension of prolapsed (POP Stage ≥ 2) uterus" (p = 0.025; odds ratio = 7.00) significantly affected recurrence after LSC and TVM, respectively. CONCLUSION: POP repair by LSC or TVM using the new lightweight polypropylene meshes seems to be safe and has comparable outcomes, but limitations may vary.

OBJECTIVE: Primary adenoid cystic carcinoma (ACC) of Bartholin's gland is a rare gynecologic malignancy. We report two cases from primary treatment to recurrence and the adjuvant treatment. CASE REPORT: A woman aged 37 years presented with a mass on the right posterior labia minor and underwent right radical hemi-vulvectomy and right-side inguino-femoral node dissection. Final pathology showed ACC arising from Bartholin's gland with positive margins. She received adjuvant external beam radiation to the pelvis, right vulva, and groin area. However, distal metastasis occurred 42 months after initial treatment and she eventually died of multiple metastases. Another woman aged 48 years presented with a mass on the right posterior labia with intermittent pain. She underwent right hemi-vulvectomy and right inguino-femoral lymph node dissection only because pathology showed ACC of Bartholin's gland with negative surgical margins. Lung metastasis occurred 59 months after initial treatment. She took tamoxifen only and achieved stable disease status for 4 years. CONCLUSION: To date, about 70 cases have been reported. We treated our second patient with antiestrogen therapy for 4 years and achieved good quality of life and stable disease status. However, further study on hormone therapy for ACC of Bartholin's gland is needed.

OBJECTIVE: We describe the serial computed tomography (CT) findings of extensive hepatic infarction and successful plasma exchange therapy in a severe preeclamptic woman with postpartum HELLP syndrome. CASE REPORT: A 38 year-old woman presented with elevated blood pressure of 140-180/90-120 mmHg and 3+ proteinuria at 28 weeks of gestation. Two days after admission, the patient suddenly complained of severe epigastric pain and headache. Her blood pressure rose sharply to 195/120 mmHg. A 980 g female was delivered by emergency cesarean section. Following delivery, the patient's clinical condition and laboratory values deteriorated, with progressive liver insufficiency (peak AST level = 4246 IU/L, ALT = 3685 IU/L, LDH = 6237 IU/L, platelets = 72,000/mm(3)). Two consecutive plasma exchanges (PEX) were undertaken on the 3(rd) and 4(th) postpartum day. A contrast-enhanced CT of the abdomen performed 8 days postpartum showed geographically wedge-shaped areas of low attenuation, with a mottled appearance in the right hepatic lobe. Shortly thereafter, the patient recovered and all laboratory parameters gradually normalized 3 weeks after delivery. Follow-up CT-scan of the liver 2 months postpartum showed no evidence of infarction, with complete recovery. CONCLUSION: We recommend that severely ill patients with HELLP syndrome having epigastric pain should undergo CT imaging of the liver. A trial of postpartum PEX therapy should be considered for treatment of the HELLP syndrome complicated with hepatic infarction, which is recalcitrant to conventional medical management, and fails to abate within 72-96 hours of delivery.
