Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital anomaly of the genitourinary tract comprising uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Patients with HWW syndrome usually present symptoms such as dysmenorrhea, abdominal pain, pelvic mass, and purulent vaginal discharge. If not treated at an appropriate time, complications such as infertility, endometriosis, pyosalpinx, and subsequent pelvic adhesions may occur. Here, we report a case of HWW syndrome in a 7-year-old-girl who was also diagnosed as having central precocious puberty. She was brought to the pediatric department with chief complaints of lump in her breast and vaginal discharge. When she was around 2 months old, she was confirmed to have a single kidney on ultrasonography. We checked her past medical history and diagnosed her as having HWW syndrome based on the results of imaging studies, including abdominal ultrasonography and pelvic magnetic resonance imaging. She underwent treatment with gonadotropin-releasing hormone analogue for 2 years. During 24 months of follow-up, she showed no serious problems or complications. If renal anomalies are identified immediately after birth or in infancy, further screening tests should be conducted prior to menstruation for determining congenital abnormalities of the reproductive tract and vice versa.

Background: Cervical cancer is the second most common cancer among females across the world. It is a preventable cancer and early detection is very feasible. This study aimed to identify which women characteristics are potentially associated with and may have an important in uence on the uptake of cervical cancer screening in Kurdish women living in the west of Iran.. Materials and Methods: A cross sectional study was conducted in late 2014. A random sample of women aged 40 years and above without history of cervical cancer and identi ed as Kurdish background were selected and interviewed by two trained interviewers. Information about sociodemographic and reproductive factors, history of diseases, and cervical screening was collected using a questionnaire and women who had undergone a hysterectomy were excluded. Univariate analyses were used to describe the general characteristics of the study population. Multivariable logistic regression models with self-reported screening history were used to estimate odds ratios (ORs) with 95% con dence intervals (CI). Signi cance was considered at the 5% level. Results: A total of 561 women were included in this study (mean age $43.6{\pm}5.17$ years) participation in cervical screening at least once was about 32%. Cervical screening uptake percentage was signi cantly lower among people over 60 years of age (adjusted OR= 0.26, 95% CI: 0.11-0.64), and those who were illiterate (OR= 0.41 95% CI: 0.23-0.73) and post-menopausal (OR= 0.56, 95% CI: 0.35-0.91). Women with ${\leq}1$ child were less likely to report a Pap test (adjusted OR=0.43 95%CI: 0.13-1.37) Cervical screening uptake was higher among women with health insurance (OR= 2.31, 95% CI: 1.50-3.56). Conclusions: Cervical screening participation in this study was low compared to other studies in developed countries. The screening uptake was different based on age, education, parity, insurance coverage and menopausal status. It is recommended to target these groups of women in cervical screening program.

Background: There have been few studies of Asian ovarian cancer and benign tumors. The primary aim of this paper was to report the protocol of the Ko-EVE study to examine epidemiological and molecular factors for ovarian cancer and benign neoplasms and to ascertain the major risk factors for ovarian cancer control in Korea. Methods: This case-control study covers incident epithelial ovarian cancers and benign neoplasms, four major centers participating in enrolling incident cases and 3 hospitals enrolling healthy controls among health examinees. Standardized questionnaires were administered by trained interviewers, including sections on socio-demographics characteristics, past medical history, medication usage, family history, lifetime consumption of alcohol and tobacco, diet, physical activity, and reproductive factors for women. Various biological specimens were collected in the biorepository according to the standardized protocol. Annual follow-up for cancer cases and follow-up at the 1st year for benign tumor cases are performing to evaluate treatment effect and progression. Passive follow to see long-term survival will be conducting using record linkage with national data. Results: The total number recruited in 2010-2011 was 246 epithelial ovarian cancer cases, 362 benign epithelial tumors and 345 controls. We are planning to collect subjects for at least 1,500 sets of ovarian cancer, 2,000 benign tumors and 1,500 controls till 2018. Conclusions: The Ko-EVE will provide unique and important data to probe the etiology and natural history of Korean epithelial ovarian cancer. It will be continued by genomic and proteomic epidemiological analyses and future intervention studies for the prevention of ovarian cancer among Koreans.

Life table experiments were performed in order to examine the effects of food quality on Moina macrocopa fed with four kinds of algal foods, Botryococcus sp., Scenedesmus subspicatus, Selenastrum capricornutum, and Chlorella sp., at $20^{\circ}C$ . The temperature effects on M. macrocopa were also assessed, feeding Chlorella at $17^{\circ}C$,$20^{\circ}C$,$25^{\circ}C$, and a combination of $28^{\circ}C$ (light) and $25^{\circ}C$ (dark). The cartilaginous Botryococcs cells were Inappropriate food for Moina. Among the foods tested, Chlorella was the food of the best quality in all accounts of life history traits. Moina grown on Chlorella showed higher net reproductive rate ($R_0$), longer mean and maximum longevities, earlier mean age at maturity, longer mean carapace length at maturity, larger mean clutch size, and shorter mean time interval between clutch productions than those grown on Selenastrum and Scenedesmus. An optimal temperature for Moina was $20^{\circ}C$ . When Moina were grown on Chlorella at $20^{\circ}C$, they showed the highest r, the highest $R_0$, the shortest T, the longest mean longevity, the earliest mean age at maturity, the longest mean carapace length at maturity, and the largest mean clutch size. The results of life table experiments showed that the individual and population growth patterns were much more affected by low temperature $17^{\circ}C$, than by high temperature ($\geq 20^{\circ}C$). In the optimal condition, the r value was very high, 5.1 in $d^{-1}$. In conclusion, the food quality and the temperature are the most important factors to govern the size and continuity of Moina population, by which the individual growth rates and reproductivity of members in the population can be controlled to survive in their environment such as small and temporary water bodies in nature.

환경변화는 생물의 성장과 번식 등의 생활사에 영향을 주며, 생물은 살아가는 서식환경에서 생태적 적합도를 가장 극대화 시킬 수 있도록 적응되어 왔다. 본 연구에서는 동적상태의존모델을 이용하여 수온과 용존산소량의 변화가 어류의 초기 성장과 체내 스트레스 누적 과정에 미치는 영향을 분석하였다. 본 연구에서 제시한 어류의 생활사 모델은 취식 행동이 성장과 체내 스트레스 누적에 영향을 받는다고 가정하였다. 또한 수온과 용존산소량의 임계점은 가장 빠른 성장속도를 유도하는 수온과 용존산소량으로 가정하였다. 이에 모델은 수온과 용존산소량의 임계점에서 성장속도가 가장 빨랐으며 임계점보다 크거나 낮은 경우 성장속도는 느렸다. 용존산소량의 저산소 상태는 체내에 누적된 스트레스양의 증가로 성장속도는 느렸고, 고산소 상태는 성장속도를 향상 시켰으나 누적된 스트레스로 신체 크기를 감소시켰다. 본 연구를 통해 환경변화가 생물에 미치는 영향을 예측하는데 있어 단일 또는 독립적인 환경요인 보다 복합적 요인들의 영향이 높음을 보였다. 따라서 환경영향평가에서 환경변화에 대한 영향 예측을 향상시키기 위하여 생리생태학적 측면에서의 복합적 환경 요인을 평가에 도입이 필요하고 또한 관련된 기법 개발에 대한 연구가 후속 되어야 한다.

연구배경 : 폐 림프관평활근종증은 주로 가임연령의 여성에 발생하는 매우 드문 질환으로 치료에도 불구하고 점차 진행하여 호흡부전에 이르는 무서운 질형이다. 그러나 이 질환의 임상경과는 아직 정확하게 알려져 있지 않고 20여년전부터 항에스트로젠제재가 치료에 사용되고 있으나 그 효과에 대해서도 논란이 있는 실정이다. 저자들이 경험한 4례의 폐 림프관평활근종증 증례를 보고하고 극내 폐 림프관평활근종증의 임상적 고찰을 하여 폐 림프관평활근종증에 대한 이해를 돕고자 본 연구를 시행하였다. 방법 : 국내 림프관평활근종증 12례중 199년 2월 일본 교또에서 열린 림프관평활근조증 심포지움에서 국내 증례의 임상적, 방사선학적, 병리학적 소견에 대해 토의한 결과 최종진단에 이의가 제기된 2례를 제외한 10예의 임상소견, 방사선소견과 병리소견을 검토하였다. 결과 : 모든 환자는 여성이었으며 평균연령은 $33{\pm}7$세 였다. 가장 흔한 증상은 노작성 호흡곤란이었고 대부분에서 재발성 기흉의 병력이 관찰되었다. 폐기능검사상 전례에서 폐확산능의 감소가 있었다. 전예에서 고해상도 전산화단층촬영상 특정적인 낭이 전폐야에서 관찰되었다. 대부분 호르몬요법으로 증상의 호전을 보이지 않았다. 결론 : 재발성 기흉의 병력과 노작성 호흡곤란을 호소하는 가임기 여성에서는 폐 림프관평활근종증의 가능성을 반드시 염두에 두어야하고 의심되면 우선 고해상도 전산화단층촬영으로 특징적인 낭 유무를 확인하고 필요하면 개흉폐생검으로 확진해야 할 것으로 판단된다.

Objective: Extrauterine formation of decidua of stromal cells has been well described, particularly in the cervix and ovary. The apparent hormonal mechanisn of this phenomenon suggestes a relationship to endometriosis. Whether formation of ectopic decidua represents a marked progestational response of endometriosis or an independent peritoneal-stromal reaction to pregnancy is unclear. This study was designed to determine the prevalence of deciduosis in the patients whose fertility were proven. Design: Prospective study of patients who had undergone cesarean delivery without history of endometriosis. Materials and Methods: The study was performed in 179 full tenn pregnant women. During the cesarean section, the pelvic organs were thoroughly investigated and the biopsies were collected at the lesions suspicious endometriosis. And then microscopic examination of removed tissues were done. Results: Of the 179 patients who underwent cesarean delivery, 48 women (26.8%) had the lesions suspicious endometriosis such as adhesion, pigmented spots. The ovary was the most frequently ocurred site (79.2%). Microscopically, decidual cells were observed in 34 cases (70.8%) of 48 biopsed patients. Conclusion: Endometriosis has been known to be associated with subfertility. Our observations found the prevalence of deciduosis was 19.0% (34/179) in tenn pregnant women whose fertilites were proven. We suggests that the deciduosis maya manifestation of endometriosis during pregnancy. However, further follow up study should be done to confirm this clinicopathologic process.

In 105 patients with the past history of poor response to the previous controlled ovarian hyperstimulation(COH) due to poor follicular growth or premature LH surge, the effectiveness of pituitary suppression with gonadotropin-releasing hormone agonist(GnRH agonist) in IVF/GIFT program was evaluated in 112 cycles of COH using a combination regimen of Leuprolide acetate (Lupron TAP Pharmaceuticals, USA) and FSH/hMG or pure FSH from May to December, 1989 at SNUH. Starting on day 21 of the menstrual cycle(MCD #21, Day 1), Lupron (1.0mg/day, subcutaneous) was administered once a day till next MCD #3(suppression phase). After the confirmation of pituitary suppression, ovarian follicular growth was stimulated with FSH/hMG or pure FSH from MCD #3(Day + 1), and Lupron was continued with hMG or FSH until hCG administration (D 0) (stimulation phase). After suppression phase, serum E2 level decreased from 183.7${\pm}$95.1(Day 1) to 17.4${\pm}$12.3pg/ml (Day +1), and serum progesterone level from 19.17${\pm}$8.67 to 0.12${\pm}$0.05ng/ml. But there was no decresas in serum LH and FSH levels; LH from 12.74${\pm}$6.21 to 15.49${\pm}$4.93mIU/ml,FSH from 7.60${\pm}$3.84 to 8.58${\pm}$3.15 rnlU/ml. There was no occurrence of premature LH surge during COH. Eleven cycles(9.8%) were cancelled due to poor follicular growth during stimulation phase, and 3 cycles (3.0%) failed in the transvaginal oocytes fretrieval. Serum E2 level was 1366.8${\pm}$642.4 on D 0 and 1492.3${\pm}$906.9pg/ml on D+1. 7.00${\pm}$3.32 follicles(FD${\geq}$12mm) were observed on D 0, and 6.11${\pm}$4.15 oocytes were retrieved, with the oocyte retrieval rate per follicle of 95.0%. 3.59${\pm}$2.57 oocytes were fertilized and cleaved with the oocyte cleavage rate of 55.7%. In 83 IVF patients, 4.08${\pm}$2.39 embryos were transferred, and 16 pregnancies were obtained with the pregnancy rate per ET 2.39 mebryos were transferred, and 16 pregnancies were obtained with the pregnancy rate per ET of 19.3%. In 6 GIFT patients, 7.83${\pm}$3.31 oocytes were retrieved and transferred with maximum number of 6, but no pregnancy was obtained. When compared with the previous 108 cycles of COH using FSH/hMG or pure FSH regimen, the cancellation rate during COH was significantly decreased, and all the parameters of the outcome of COH including the pregnancy rate were increased. These data suggest that GnRH agonist therapy for pituitary suppression is an effective adjunct to the current gonadotropin regimens for COH in IVF/GIFT and can increase the probability of oocytes retrieval and pregnancy, especially in the previous poor responders.

Hypochondroplasia (HCH) is an autosomal dominant inherited skeletal dysplasia, usually caused by a heterozygous mutation in the fibroblast growth factor receptor 3 gene (FGFR3). A 27-year-old HCH woman with a history of two consecutive abortions of HCH-affected fetuses visited our clinic for preimplantation genetic diagnosis (PGD). We confirmed the mutation in the proband (FGFR3:c.1620C>A, p.N540K), and established a nested allele-specific PCR and sequence analysis for PGD using single lymphocyte cells. We performed this molecular genetic analysis to detect the presence of mutation among 20 blastomeres from 18 different embryos, and selected 9 embryos with the wild-type sequence (FGFR3:c.1620C). A successful pregnancy was achieved through a frozen-thawed cycle and resulted in the full-term birth of a normal neonate. To the best of our knowledge, this is the first report of a successful pregnancy and birth using single-cell allele-specific PCR and sequencing for PGD in an HCH patient.
