Review and Future Perspectives of the Korea Counseling Center for Fertility and Depression Based on User Characteristics: Focusing on Those During Pregnancy and Early After Delivery

Purpose@#This study examined the current status of counseling services provided by the Korea Counseling Center for Fertility and Depression, analyzing the characteristics of peripartum women and baby-rearing mothers and establishing guidelines for providing psychological support, and suggesting measures for improving the system. @*Methods@#Data on 3,660 peripartum women & their spouses and baby-rearing mothers counseled through the service over the last 4 years were collected and a demographic analysis was conducted. By analyzing the clinical information of 216 peripartum women and 219 baby-rearing mothers who have registered with the Center and received routine counseling services, factors affecting depression were identified. Finally, a paired sample t-test was conducted to verify the effect of counseling services. @*Results@#An overall 20.4% of pregnant women & their spouses were screened for high risk for depression, of whom 27.3% received registered counseling services; further, 26.2% of baby-rearing parents were at high-risk group for depression, of whom 25% received registered counseling services. Results of a logistic regression analysis suggested that, for peripartum women, level of education and conflicts with partner and family were the crucial factors predicting moderate or severe depression. For baby-rearing mothers, obstetric history of spontaneous abortion was the crucial predicting factor. @*Conclusion@#For the early detection and prevention of peripartum depression, screening tests that start from early pregnancy should be routinely administered. Further, continuous management—covering the periods before and after childbirth—should be provided by establishing organic ties between domestic projects.

Distribution of lymphocele following lymphadenectomy in patients with gynecological malignancies

Objective@#This study identified the distribution of lymphocele, as well as the factors associated with lymphocele formation, in patients undergoing pelvic and/or para-aortic lymph node dissection (PLND and/or PALND) for gynecologic malignancies. @*Methods@#This study was retrospective, and data were collected from patients who underwent surgical procedures including lymphadenectomy due to gynecologic malignancies from March 2013 to May 2016. Lymphocele was defined by postoperative computer tomography within 2 weeks after surgery. @*Results@#A total of 116 patients underwent lymphadenectomy, of whom, 47 (42.0%) developed lymphocele and 14 (12.1%) had symptomatic lymphocele formation. The affecting factors of lymphocele formation were PLND concomitant with PALND and a large amount of blood loss ≥600 mL (P=0.030 and P=0.006, respectively). All clinical factors were not significantly different between patients with symptomatic and asymptomatic lymphocele. Lymphocele developed more frequently in the left side (67.1%) of the body compared to the right side (48.7%), and in the pelvic area (75.9%) compared to the para-aortic area (24.1%, P<0.001, both). @*Conclusion@#Lymphocele formation is more prevalent in the left and pelvic area of the body compared to the right and paraaortic side. PLND concurrent with PALND and large amounts of blood loss were significant risk factors for lymphocele formation.

Lower limb compartment syndrome by reperfusion injury after treatment of arterial thrombosis post-laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer

Compartment syndrome is a clinical condition associated with decreased blood circulation that can lead to swelling of tissue in limited space. Several factors including lithotomy position, prolonged surgery, intermittent pneumatic compressor, and reperfusion after treatment of arterial thrombosis may contribute to compartment syndrome. However, compartment syndrome rarely occurs after gynecologic surgery. In this case, the patient was diagnosed as compartment syndrome due to reperfusion injury after treatment of arterial thrombosis, which occurred after laparoscopic radical hysterectomy and pelvic lymph node dissection for cervical cancer. Despite its rarity, prevention and identifying the risk factors of complication should be performed perioperatively; furthermore, gynecologist should be aware of the possibility of complications.

Effects of laser-assisted hatching and exposure time to vitrification solution on mouse embryo development / 대한생식의학회지

OBJECTIVE: This study was conducted to investigate the efficacy of laser-assisted hatching (LAH) and various vitrification times for embryonic development and blastocyst cell numbers. METHODS: First, 2-cell and 8-cell embryos were collected by flushing out the oviducts. In the control groups, they were vitrified for 8 or 10 minutes without LAH. The LAH groups underwent quarter laser zona thinning-assisted hatching before vitrification (4, 6, and 8 minutes or 4, 7, and 10 minutes, respectively). After incubation, double-immunofluorescence staining was performed. RESULTS: The hatched blastocyst rate 72 hours after the 2-cell embryos were thawed was significantly higher in the 2LAH-ES8 group (33.3%) than in the other groups (p < 0.05). In the control-8 group (22.1±4.6), the cell number of the inner cell mass was higher than in the LAH groups (p < 0.05). The number of trophectoderm cells was higher in the 2LAH-ES6 group (92.8±8.9) than in the others (p < 0.05). The hatched blastocyst rate 48 hours after the 8-cell embryos were thawed was higher in the 8LAH-ES4 group (45.5%) than in the other groups, but not significantly. The inner cell mass cell number was highest in the 8LAH-ES7 group (19.5±5.1, p < 0.05). The number of trophectoderm cells was higher in the 8LAH-ES10 group (73.2±12.1) than in the other groups, but without statistical significance. CONCLUSION: When LAH was performed, 2-cell embryos with large blastomeres had a lower hatched blastocyst rate when the exposure to vitrification solution was shorter. Conversely, 8-cell embryos with small blastomere had a higher hatched blastocyst rate when the exposure to vitrification solution was shorter.

The effect of artificial shrinkage and assisted hatching on the development of mouse blastocysts and cell number after vitrification / 대한생식의학회지

OBJECTIVE: The goal of this study was to ascertain optimal assisted hatching (AH) method in frozen embryo transfer. We compared the effect of depending on whether mechanical or laser-AH was performed before or after the vitrification of embryo development rate and blastocyst cell numbers. METHODS: In order to induce superovulation, pregnant mare's serum gonadotropin followed by human chorionic gonadotropin were injected into 4- to 5-week-old female mice. 2-cell embryos were then collected by flushing out the oviducts. The Expanded blastocysts were recovered after the collected embryos were incubated for 48 hours, and were then subjected to artificial shrinkage (AS) and cross-mechanical AH (cMAH) or quarter-laser zona thinning-AH (qLZT-AH) were carried out using the expanded blastocysts before or after vitrification. After 48 hours of incubation, followed by vitrification and thawing (V-T), and blastocysts were fluorescence stained and observed. RESULTS: The rate of formation of hatched blastocysts after 24 and 72 hours of incubation was significantly higher in the AS/qLZT-AH/V-T group than in the other groups (p<0.05). The cell number of the inner cell mass was higher in AS/V-T/non-AH and AS/V-T/cMAH groups than those of others (p<0.05). In the control group, the number of trophectoderm and the total cell number were higher than in the AS-AH group (p<0.05). CONCLUSION: The above results suggest that AS and AH in vitrification of expanded blastocysts lead to the more efficient formation of hatched blastocysts in mice.

Involvement of PI3K/AKT and MAPK Pathways for TNF-alpha Production in SiHa Cervical Mucosal Epithelial Cells Infected with Trichomonas vaginalis

Trichomonas vaginalis induces proinflammation in cervicovaginal mucosal epithelium. To investigate the signaling pathways in TNF-alpha production in cervical mucosal epithelium after T. vaginalis infection, the phosphorylation of PI3K/AKT and MAPK pathways were evaluated in T. vaginalis-infected SiHa cells in the presence and absence of specific inhibitors. T. vaginalis increased TNF-alpha production in SiHa cells, in a parasite burden-dependent and incubation time-dependent manner. In T. vaginalis-infected SiHa cells, AKT, ERK1/2, p38 MAPK, and JNK were phosphorylated from 1 hr after infection; however, the phosphorylation patterns were different from each other. After pretreatment with inhibitors of the PI3K/AKT and MAPK pathways, TNF-alpha production was significantly decreased compared to the control; however, TNF-alpha reduction patterns were different depending on the type of PI3K/MAPK inhibitors. TNF-alpha production was reduced in a dose-dependent manner by treatment with wortmannin and PD98059, whereas it was increased by SP600125. These data suggested that PI3K/AKT and MAPK signaling pathways are important in regulation of TNF-alpha production in cervical mucosal epithelial SiHa cells. However, activation patterns of each pathway were different from the types of PI3K/MAPK pathways.

The effect of various assisted hatching techniques on the mouse early embryo development / 대한생식의학회지

OBJECTIVE: In search of an ideal method of assisted hatching (AH), we compared the effects of conventional micropipette-AH and laser-AH on the blastocyst formation rate (BFR) and blastocyst cell numbers. METHODS: Four- to five-week-old ICR female mice were paired with male mice after superovulation using Pregnant mare's serum gonadotropin (PMSG) and hCG. The two-cell embryos were flushed from the oviducts of female mice. The retrieved two-cell embryos underwent one of five AH procedures: single mechanical assisted hatching (sMAH); cross mechanical assisted hatching (cMAH); single laser assisted hatching (sLAH); quarter laser assisted hatching (qLAH); and quarter laser zona thinning assisted hatching (qLZT-AH). After 72 hours incubation, double immunofluorescence staining was performed. RESULTS: Following a 72 hours incubation, a higher hatching BFR was observed in the control, sMAH, cMAH, and sLAH groups, compared to those in the qLAH and qLZT-AH groups (p<0.05). The hatched BFR was significantly higher in the qLAH and qLZT-AH groups than in the others (p<0.05 for each group). The inner cell mass (ICM) was higher in the control and sMAH group (p<0.05). The trophectoderm cell number was higher in the cMAH and qLAH groups (p<0.05). CONCLUSION: Our results showed that the hatched BFR was higher in groups exposed the the qLAH and qLZT-AH methods compared to groups exposed to other AH methods. In the qLAH group, although the total cell number was significantly higher than in controls, the ICM ratio was significantly lower in than controls.

Two-port access versus four-port access laparoscopic ovarian cystectomy

OBJECTIVE: This study was conducted to compare the surgical outcomes between two-port access and four-port access laparoscopic ovarian cystectomy. METHODS: Four hundred and eighty nine patients who had received two-port access laparoscopic ovarian cystectomy (n=175) and four-port access laparoscopic ovarian cystectomy (n=314) in Chungnam National University Hospital from January 2009 to August 2012 were analyzed retrospectively. The data were compared between the bilaterality of the cysts and cyst diameter of less than 6 cm and 6 cm or more. RESULTS: There were no significant differences in patient's age, parity, body weight, body mass index and history of previous surgery between the two-port and four-port access laparoscopy group. Bilaterality of ovarian cysts was more in fourport access laparoscopy group (13.7% vs. 32.5%, P=0.000). There were no significant differences in operation time, hemoglobin change, hospital stay, adhesiolysis, transfusion, and insertion of hemo-vac between the two-port and four-port access laparoscopy group for size matched compare. However additional analgesics were more in four-port access laparoscopy group for unilateral ovarian cystectomy. CONCLUSION: Two-port access laparoscopic surgery was feasible and safe for unilateral and bilateral ovarian cystectomy compare with four-port access laparoscopic surgery.

Trichomonas vaginalis Metalloproteinase Induces mTOR Cleavage of SiHa Cells

Trichomonas vaginalis secretes a number of proteases which are suspected to be the cause of pathogenesis; however, little is understood how they manipulate host cells. The mammalian target of rapamycin (mTOR) regulates cell growth, cell proliferation, cell motility, cell survival, protein synthesis, and transcription. We detected various types of metalloproteinases including GP63 protein from T. vaginalis trophozoites, and T. vaginalis GP63 metalloproteinase was confirmed by sequencing and western blot. When SiHa cells were stimulated with live T. vaginalis, T. vaginalis excretory-secretory products (ESP) or T. vaginalis lysate, live T. vaginalis and T. vaginalis ESP induced the mTOR cleavage in both time- and parasite load-dependent manner, but T. vaginalis lysate did not. Pretreatment of T. vaginalis with a metalloproteinase inhibitor, 1,10-phenanthroline, completely disappeared the mTOR cleavage in SiHa cells. Collectively, T. vaginalis metallopeptidase induces host cell mTOR cleavage, which may be related to survival of the parasite.

The influence of serum substituents on serum-free Vero cell conditioned culture media manufactured from Dulbecco's modified Eagle medium in mouse embryo culture

OBJECTIVE: This study was conducted to examine the influences of supplementation of the serum substituents and available period of serum-free Vero cell conditioned media (SF-VCM) manufactured from Dulbecco's modified Eagle medium cultured with Vero cells for in vitro development of mouse preimplantation embryos. METHODS: A total of 1,099 two-cell embryos collected from imprinting control region mice were cultured in SF-VCM with 10% and 20% human follicular fluid (hFF), serum substitute supplement (SSS), and serum protein substitute (SPS). Development of embryos was observed every 24 hours. Results between different groups were analyzed by chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: The rates of embryonic development cultured in SF-VCM supplemented with serum substituents were significantly higher compare with serum-free group (P < 0.05). The rates of embryonic development after 48 hours (morula< or =) and 96 hours (blastocyst< or =) were significantly higher in 20% SSS and 10% SPS than in 20% hFF supplementation (P < 0.05). And the rates of embryonic development after 96 hours (hatching blastocyst< or =) were significantly higher in 10% SPS (94.5%) than in 20% SSS (82.6%) and 20% hFF supplementation (68.5%). The rates of embryonic development according to storage period of the SF-VCM supplemented with 10% SPS showed no significant difference between control, 2 weeks and 4 weeks group. However developmental rate in 6 weeks storage group was significantly lower than other groups. CONCLUSION: The rate of embryonic development after 96 hours (hatching blastocyst< or =) was significantly higher in SF-VCM supplemented with 10% SPS. And storage period of media up to 4 weeks did not affect on embryonic development.

Meconium peritonitis: prenatal diagnosis and postnatal outcome / 대한산부인과학회지

OBJECTIVE: To detect meconium peritonitis for the fetal period is important for prenatal counseling. The aim of this study was to evaluate prenatal ultrasound finding for diagnosing meconium peritonitis and postnatal clinical course and outcomes. METHODS: The prenatal and postnatal medical records of all patients to our institutions with confirmed meconium peritonitis were reviewed, with emphasis on prenatal ultrasound findings, postnatal investigations, operative findings, outcomes of meconium peritonitis. RESULTS: Fourteen fetuses were confirmed to have meconium peritonitis at birth by operation. Eight cases were diagnosed correctly because of prenatal ultrasound showing ascites and calcification/dilated or hyperechoic bowel loops. In the other 6 cases, prenatal ultrasound showed only ascites. One patient was operated on first day of life and its intra-operative finding was malrotation of small bowel, volvulus with strangulation, perforation and jejunal atresia. Most cases were operated on 2nd or 3rd day of life. Intra-operative findings were ileal atresia and perforation in 11 cases and jejunal atresia and perforation in 3 cases. Four patients underwent ileostomy but all patients survived and prospered. CONCLUSION: All patients do not present typical prenatal ultrasound findings of meconium peritonitis. Therefore, even in pregnancies associated with isolated ascites, meconium peritonitis should be taken into consideration. Favorable outcome of intrauterine meconium peritonitis is reassuring in prenatal counselling and stems from multidisplinary team approach.

Studies on development of serum-free conditioned media using Vero cells and DMEM with controlled concentration of glucose and pyruvate / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to examine in vitro development of early preimplantation mouse embryos in various kind of serum-free conditioned media (SF-VCM) manufactured from DMEM cultured with Vero Cells. METHODS: A total of 846 two-cell mouse embryos were cultured in different kind of SF-VCM. SF-VCMs were divided into SF-VCM-10, -30 and -50 by media volume using DMEM #1 media, and divided into SF-VCM #1, #2 and #3 by controlled concentration of glucose and pyruvate (manufactured by DMEM #1: mixed three volume of DMEM-G (DMEM with glutamine without glucose and pyruvate) and one volume of DMEM-GGP (DMEM with glutamine, glucose, pyruvate), #2: mixed same volume of DMEM-G and DMEM-GGP and #3: mixed one volume of DMEM-G and three volume of DMEM-GGP, respectively). Experimental groups were mainly added 10% SSS, and 20% hFF was added to only Control group co-cultured with Vero cells. Development of embryos was observed every 24 hours. Results between different groups were analyzed using Chi-square test, and considered statistically significant when P-value was less than 0.05. RESULTS: In vitro developmental rate by each cleavage stages of mouse embryos cultured in SF-VCMs with a various volumes were significantly (P<0.05) higher in SF-VCM-30 (morula< or =: 97.2%, Blastocyst (BL)< or =: 97.2%, Hatching BL< or =: 82.2%) than other groups. In the rate of development on in vitro co-culture vs. a various SF-VCMs manufactured by DMEM controlled concentration of glucose and pyruvate, Group I (SF-VCM #1) was higher than other groups in each cleavage stages (morula< or =: 98.1%, Blastocyst (BL)< or =: 97.1%, hatching BL< or =: 81.7%, respectively). Moreover, specially, in the developmental rate into the hatching blastocyst < or = after 96 hours in vitro culture, Group I (81.7%) was significantly higher than control group (67.6%, P<0.05). CONCLUSION: SF-VCM #1 manufactured by volume of 30 mL DMEM #1 media cultured in vitro for 48 hours in 250 mL flask was the most effective on in vitro developmental rate of mouse preimplantation embryos. Therefore, it is expected that SF-VCM #1 has application to human IVF-ET.

Laparoscopic repair of vesicovaginal fistula / 대한산부인과학회지

Vesicovaginal fistula (VVF) is one of the most serious surgical complication in gynecologic surgery. Surgical approach to repair this condition can be performed by transvaginal or transabdominal. However, laparoscopic repair of VVF may be an alternative surgical method. We present four cases of VVF treated with transperitoneal laparoscopic technique. Laparoscopic repair is a feasible, safe and efficacious minimally invasive approach for the management of VVF. We believe that this method provides excellent results and may result in lower morbidity, shorter hospital stay, and quicker recovery than the abdominal or transvaginal approaches.

Six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap in MRKH syndrome / 대한산부인과학회지

Vaginal agenesis is rare gynecologic condition, and the most common etiology is Mayer-Rokitansky-Kster-Hauser (MRKH) syndrome, characterized by the absence of uterus and vagina and presence of normal ovaries and tubes. In such patients, the evaluation for associated malformations as well as careful non-surgical and surgical approach are essential. The neovaginoplasty is an important issue for these patients in regard of functional and psychological standpoint. There are many options available for creation of neovagina. We report six cases of laparoscopic assisted neovaginoplasty using pelvic peritoneal flap.

Three cases of vaginal evisceration after laparoscopic hysterectomy / 대한산부인과학회지

Vaginal evisceration is a rare but life threatening complication of gynecologic surgery. Most of them occur after abdominal or vaginal hysterectomy. The incidence after laparoscopic hysterectomy is unknown. The incidence of evisceration in the patients undergoing laparoscopic hysterectomy in our hospital was 0.1 %. The rapid recovery after laparoscopic hysterectomy, compared with abdominal hysterectomy, is widely acknowledged. Swift return to everyday activities and early resumption of intercourse could predispose to rupture of vaginal vault. Upon discharge, patients undergoing laparoscopic hysterectomy should be given careful instructions to avoid coitus until complete healing of vaginal vault. We described three cases of vaginal evisceration after laparoscopic hysterectomy including a review of the literature.

A case report of recurrent Meckel Gruber syndrome / 대한산부인과학회지

Meckel Gruber syndrome consisting of an occipital encephalocele, polycystic kidney disease and polydactyly is a rare autosomal recessive disorder with a recurrence risk of 25%. Targeted ultrasonography in late embryonic or early fetal stages of pregnancy has great importance in diagnosis and management of affected pregnancy in high risk groups due to incomplete genetic mapping of meckel syndrome gene (MKS). We present a case of prenatal diagnosis at 14 weeks' gestational age of Meckel Gruber syndrome in a woman, who experienced same disorder in her previous pregnancy.

The factors influencing pregnancy after surgery in infertile patients with severe endometriosis / 대한산부인과학회지

OBJECTIVE: Endometriosis is assumed to be one of the causes of infertility, although the mechanism remains unclear. The purpose of this study was to determine the prognostic factors for the fertility in women with severe endometriosis. METHODS: Clinical data of 78 consecutive infertile patients who had taken surgery for stage III and IV endometriosis were retrospectively analyzed in two groups: A- pregnant after surgery (n=43, 55.1%): B- non-pregnant after surgery (n=35, 44.9%). All patients were treated with GnRHa after surgery. Each group were compared age, BMI, duration of infertility, stage of endometriosis, size and number of endometrioma, peritoneal implant outside the pelvic cavity, peritubal adhesion, ovarian adhesion and cul-de-sac obliteration. RESULTS: Among these factors, duration of infertility (p=0.03), peritoneal implant (p=0.01), tubal adhesion (p=0.04) and ovarian adhesion (p=0.02) were significantly different. However, patients' age, BMI, size and number of endometrioma, cul-de-sac obliteration and stage of endometriosis did not showed significantly different. CONCLUSION: We concluded that the duration of infertility and tubal and ovarian adhesion are important factors for predicting pregnancy after surgery in severe endometriosis.

What is the risk factor of preeclampsia?: Hospital-based case-control study / 대한산부인과학회잡지

OBJECTIVE: To assess several variables that are known as the risk factor of preeclampsia. METHODS: We have studied with 279 pregnant women who were diagnosed with preeclampsia and went through delivery in Chungnam University from January, 1998 to December, 2002. For control group, we chose 364 non-hypertensive pregnant women who went through delivery from January, 2002 to December, 2002 through random process. Through reviewing each patient's chart, we collected data regarding age, parity, past medical history, past obstetric history, family history, presence of gestational diabetes, height, body weight, before and at the time of delivery, delivery mode and neonatal outcomes. Statistical analysis was performed using x2-test, Student t-test. A value of p below 0.05 was considered to show statistical significance. RESULTS: During the study period, 298 women had preeclampsia so that the incidence of preeclampsia was 6.0%. Age and past medical history were not related to preeclampsia. The primiparous women in this study are likely to show a higher incidence of preclampsia (OR 1.35, 95% CI 1.16-1.5, p=0.017). In addition, women whose BMI are ranged from 25.0 kg/m2 to 30.0 kg/m2 (p=0.027), and ranged from 30.0 kg/m2 to 40.0 kg/m2 (p=0.027) had a higher incidence of preeclampsia. By using a multiple logistic regression analysis about the BMI changes, we found out that there was a higher rate of preeclmapsia among pregnant women with over 7.11 kg/m2 BMI increasement compared with BMZ before pregnancy (OR=2.97, 95% CI 2.22-3.99, por=25.0 kg/m2, previous preeclampsia, family history of chronic hypertension, twin gestation showed an increased risk of preeclampsia.
