Background:
Turner syndrome (TS) is a common chromosomal abnormality, which is caused by loss of all or part of one X chromosome. Hormone replacement therapy in TS is important in terms of puberty, growth and prevention of osteoporosis however, such a study has never been conducted in Korea. Therefore, the purpose of our study was to determine relationship between the starting age, duration of estrogen replacement therapy (ERT) in TS and develop a hormone replacement protocol suitable for the situation in Korea.
Methods:
This is retrospective study analyzed the medical records in TS patients treated at the Severance hospital, Yonsei University College of Medicine, Seoul, Korea from 1997 to 2019. Total of 188 subjects who had received a bone density test at least once were included in the study. Korean National Health and Nutrition Examination Survey (KNHANES) was used for achieving bone mineral density (BMD) of normal control group. Student’s t-test, MannWhitney U test, ANOVA and correlation analysis were performed using SPSS 18.0.
Results:
Each BMD measurement was significantly lower in women with TS than in healthy Korean women. Early start and longer duration of ERT is associated with higher lumbar spine BMD but not femur neck BMD. Femur neck BMD, but not lumbar spine BMD was significantly higher in women with mosaicism than 45XO group.
Conclusion
Early onset and appropriate duration of hormone replacement therapy is important for increasing bone mineral density in patients with Turner syndrome. Also, ERT affects differently to TS patients according to mosaicism.

Background:
To assess the effectiveness of rescue cerclage concerning pregnancy and neonatal outcomes in women with acute cervical insufficiency (CI) complicated with intraamniotic inflammation (IAI) compared with those managed expectantly.
Methods:
This retrospective cohort study included 87 consecutive singleton pregnant women (17–25 weeks) with acute CI who underwent amniocentesis to assess IAI. Amniotic fluid (AF) samples were assayed for interleukin-6 to define IAI (≥ 2.6 ng/mL). Primary and secondary outcomes were assessed in a subset of CI patients with IAI. The primary outcome measures were spontaneous preterm birth (SPTB) at < 28 and < 34 weeks, and the secondary outcomes were interval from sampling to delivery, neonatal survival, neonatal birth weight, and histologic and clinical chorioamnionitis. Macrolide antibiotics were prescribed depending on the type of microorganism isolated from the AF, clinically suspected IAI, and the discretion of the attending clinician.
Results:
IAI was identified in 65.5% (57/87) of patients with CI, of whom 73.6% (42/57) were treated with macrolide antibiotics. Among the CI patients with IAI (n = 57), 40 underwent rescue cerclage and 17 were expectantly managed. The rates of SPTBs at < 28 and < 34 weeks were significantly lower and the latency period was significantly longer in the cerclage group than in the group that was managed expectantly. The median birth weight and neonatal survival rate were significantly higher in the cerclage group than in the group that was managed expectantly. However, the rates of histologic and clinical chorioamnionitis did not differ between the groups. Multivariable analyses revealed that rescue cerclage placement and administration of macrolide antibiotics were significantly associated with a decrease in SPTBs at < 28 and < 34 weeks, prolonged gestational latency, and increased likelihood of neonatal survival, after adjusting for possible confounding parameters; however, macrolide antibiotic administration did not reach statistical significance with respect to SPTB at < 34 weeks and neonatal survival (P = 0.076 and 0.063, respectively).
Conclusion
Rescue cerclage along with macrolide antibiotic treatment may positively impact pregnancy and neonatal outcomes in women with CI complicated by IAI, compared with expectant management. These findings suggest the benefit of cerclage placement even in patients with CI complicated by IAI.

Objectives:
This study used the Korean National Health and Nutrition Examination Survey (KNHANES) to determine the association between fractures and low muscle mass.
Methods:
This cross-sectional study used the 2010–2011 KNHANES data. Low muscle mass was defined as (appendicular skeletal muscle mass [kg]/Height2 [m2 ]) < 5.45 kg/m2 , which is < 2 SD below the sex-specific mean of a young reference group. Patients with T-scores between –1.0 and –2.5 indicated osteopenia, whereas those with T-scores lower than –2.5 indicated osteoporosis.
Results:
Out of 1,306 women enrolled in the study, 330 were diagnosed with low muscle mass according to the abovementioned diagnostic criterion. The prevalence of fractures at various sites was significantly higher in postmenopausal women with low muscle mass than in those without low muscle mass (relative risk [RR], 1.64; odds ratio [OR], 1.62; 95% confidence interval [CI], 1.06–2.48; P = 0.027). Furthermore, the prevalence of fractures was increased by the presence of osteopenia or osteoporosis in addition to low muscle mass (RR, 1.59; OR, 1.60; 95% CI, 1.02–2.49; P = 0.039) and by osteoporosis only (RR, 2.12; OR, 2.29; 95% CI, 1.11–4.70; P = 0.025).
Conclusions
Fracture was more prevalent in postmenopausal women with low muscle mass than in those without low muscle mass.This finding is consistent in a subgroup analysis that included women who had osteoporosis or osteopenia. Moreover, the risk of fractures increased as low muscle mass worsened.

Objective:
We aimed to determine whether ovarian-preserving surgery for adnexal torsion helps preserve ovarian function without increasing the risk of postoperative complications.
Methods:
We retrospectively evaluated 71 women who were surgically diagnosed with adnexal torsion between January 2015 and December 2019 at Severance Hospital, Yonsei University College of Medicine (ovarian preservation group, 56; oophorectomy, 15). Serum anti-Müllerian hormone (AMH) levels measured within 6 months before surgery were compared to levels measured 6-24 months after surgery. Surgical findings and postoperative complications were compared between the groups.
Results:
There was a borderline significant difference in the decrease in serum AMH levels between the oophorectomy group and ovarian preservation group before and after surgery. There were no significant differences between the groups in terms of fever, infection, or duration of admission. Discoloration of the twisted ovary was found in 27.3% and 33.3% of the patients in the ovarian preservation and oophorectomy groups, respectively. There was no difference in the decrease in serum AMH levels between patients with and those without discoloration.
Conclusion
Ovarian-preserving surgery may not increase postoperative complications in patients with adnexal torsion, even if a twisted mass is suspected to be necrotic. Moreover, the ovarian reserve may not be affected by torsion if the ovary is preserved. Conservative ovarian surgery can be safely performed to preserve the reproductive potential of women with adnexal torsion and cystic masses.

Background:
Single nucleotide polymorphisms (SNPs) are reportedly associated with repeated abortion. Thus, genetic analysis based on race is the key to developing accurate diagnostic tests. This study analyzed the genetic polymorphisms of recurrent pregnancy loss (RPL) patients among Korean women compared to the controls.
Methods:
In 53 women of RPL group and 50 controls, the genetic analysis was performed.The genotype distribution and allele frequency were analyzed statistically for the difference between the two groups. The association between each SNP marker and RPL risk was analyzed.
Results:
The genotypes of LEPR, endothelial nitric oxide synthase (eNOS), KDR, miR-27a, miR-449b, and tumor necrosis factor-alpha (TNF-α) were analyzed using odds ratio (OR) with 95% confidence intervals (CIs). Only the AG genotype of miR-449b (A>G) polymorphism showed significant association with the risk of RPL when compared to the AA genotype (OR, 2.39). The combination of GG/AG+GG/CA+AA genotypes for eNOS/ miR-449b/TNF-α was associated with 7.36-fold higher risk of RPL (OR, 7.36). The GG/ AG+GG combination for eNOS/miR-449b showed 2.43-fold higher risk for RPL (OR, 2.43). The combination of AG+GG/CA+AA genotypes for miR-449b/TNF-α showed a significant association with the risk of RPL (OR, 7.60). From the haplotype-based analysis, the G-G-A haplotype of eNOS/miR-449b/TNF-α and the G-A haplotype of miR-449b/TNF-α were associated with increased risk of RPL (OR, 19.31; OR, 22.08, respectively).
Conclusion
There is a significant association between the risk of RPL and miR-449b/TNF-αcombination, and therefore, genetic analysis for specific combined genotypes can be an important screening method for RPL in Korean women.

Theca lutein cysts are rare, benign lesions responsible for gross cystic enlargement of both ovaries during pregnancy. This condition is also termed hyperreactio luteinalis. Elevated human chorionic gonadotropin (hCG) levels or states of hCG hypersensitivity seem to promote these changes, which in up to 30% of patients produce clinical signs of hyperandrogenism. Given the self-limiting course of theca lutein cysts, which are subject to spontaneous postpartum resolution, conservative treatment is the mainstay of patient management. Described herein is a rare case of theca lutein cysts with maternal virilization that failed to regress by 9 months after childbirth. Surgical intervention was eventually undertaken, necessitated by adnexal torsion.

OBJECTIVE: This study was aimed at identifying a correlation between polycystic ovarian morphology (PCOM) and the severity of primary dysmenorrhea in young Korean women. METHODS: A total of 592 patients who visited a tertiary hospital from March 2008 to March 2015 for dysmenorrhea were examined. After excluding those with secondary causes of menstrual pain (for example, myoma, adenomyosis, endometriosis, and pelvic inflammatory disease), 361 women were recruited and retrospectively analyzed. Severe dysmenorrhea was defined as a visual analog scale (VAS) score ≥6. RESULTS: The mean patient age was 23.0±4.0 years, the average menstrual cycle length was 34.4±23.7 days, and the average pain intensity was VAS 6.7±0.1 at baseline. PCOM was assessed by ultrasound in 54 women (15%). Patients with severe menstrual pain were more likely to have irregular menstrual cycles (P=0.03) and heavy menstrual flow (P=0.01) than those with mild menstrual pain. After adjusting for weight, height, menstrual cycle interval, and menstrual flow in the logistic regression analysis, PCOM (odds ratio [OR], 2.26; 95% confidence interval [CI], 1.05–4.97; P=0.04) and heavy menstrual flow (OR, 1.85; 95% CI, 1.05–3.28; P=0.04) were found to be significant independent factors influencing pain. CONCLUSION: Our study shows that PCOM may have a correlation with the severity of primary dysmenorrhea. Since PCOM may play a role in the development of menstrual pain, patients with PCOM should be under active surveillance with resources for prompt pain management readily available. It may also be necessary to further investigate the molecular mechanisms of pain development in primary dysmenorrhea.

OBJECTIVE: This study aimed to identify factors that affect in vitro fertilization (IVF) outcomes in women with diminished ovarian reserve (DOR). METHODS: We reviewed 99 IVF cycles in 52 women with DOR between September 2010 and January 2015. DOR was defined as serum anti-Müllerian hormone level of <1.1 ng/dL or serum follicle-stimulating hormone level of ≥20 mIU/mL. Total 96 cycles in 50 patients were evaluated after excluding fertility preservation cases. RESULTS: The clinical pregnancy rate was 11.5% per cycle, and the total cancellation rate was 34.4%. Clinical pregnancy rate was significantly associated with the antral follicle count and the cause of the DOR. Age, serum anti-Müllerian hormone and follicle-stimulating hormone levels, antral follicle count, peak estradiol level, and the cause of DOR were significantly associated with cycle cancellation. However, history of previous ovarian surgery remained as a significant factor of clinical pregnancy (model 1: odds ratio [OR] 10.17, 95% confidence interval [CI] 1.46 to 70.84, P=0.019; model 2: OR 10.85, 95% CI 1.05 to 111.71, P=0.045). In cancellation models, idiopathic or previous chemotherapy group showed borderline significance (model 1: OR 3.76, 95% CI 0.83 to 17.04, P=0.086; model 2: OR 3.15, 95% CI 0.84 to 11.84, P=0.09). CONCLUSION: DOR caused by previous ovarian surgery may show better pregnancy outcome, whereas that caused by chemotherapy could significantly increase the cycle cancellation rate. Furthermore, patients with DOR who previously received gonadotoxic agents may show reduced efficacy and increased risk of IVF cycle cancellation.
