1.The Clinical Efficacy of the Low-dose FSH Regimen for Intrauterine Insemination.
Korean Journal of Fertility and Sterility 2001;28(1):47-54
OBJECTIVE: This study is to investigate the clinical efficacy of low-dose FSH regimen, comparing with clomiphene citrate and human menopausal gonadotropin (CC/hMG) regimen. METHODS: Retrospective study of the ovulatory factor infertility 39 patients who had been treated by intrauterine insemination (IUI). The 31 cycles of 21 patients were stimulated by CC/hMG regimen, the 22 cycles of 18 patients were stimulated by low-dose FSH regimen. We compared the rate of clinical pregnancy, multiple pregnancy and ovarian hyperstimulation syndrome (OHSS) of both group. RESULTS: The rate of clinical pregnancy of the CC/hMG group was 25.7% per cycle, and that of the low-dose FSH group was 54.5% per cycle. The low-dose FSH group showed a higher rate of clinical pregnancy per cycle than CC/hMG group (p=0.028). However, no differences was found statistically in the rate of multiple pregnancy and OHSS between CC/hMG group (22.2%, 5.7%) and low-dose FSH group (33.3%, 13.6%). CONCLUSION: This study showed that the low-dose FSH regimen is superior to CC/hMG regimen in getting clinical pregnancy, but dose not reduce the ovulation induction complications.

2.The Efficacy of Intracytoplasmic Sperm Injection for Previous Fertilization Failure with Conventional In Vitro Fertilization.
Korean Journal of Fertility and Sterility 2002;29(2):77-82
OBJECTIVE: This study is to evaluate the efficacy of Intracytoplasmic Sperm Injection(ICSI) for previous fertilization failure with conventional in vitro fertilization(IVF), compared with ICSI for male factor. METHOD: The author analyzed the 3 years of clinical experience with ICSI retrospectively, between the conventional IVF failure group (IVF failure) and male factor group (male factor). Surgically retrieved epididymal or testicular spermatozoa for ICSI were excluded. The IVF failure group was 13 cycles of 6 patients and male factor group was 30 cycles of 15 patients. RESULTS: The fertilization rates of the IVF failure group and male factor group were 63% and 66% respectively (p=0.635). The clinical pregnancy rates of the both group were 23.1% and 26.7% (p=0.804), and that of live birth rates were 15.4% and 13.3% (p=0.858). There were no significant difference between the two groups. CONCLUSION: The author concluded that ICSI can overcome previous fertilization failure, with the same fertilization and clinical pregnancy rates seen in patients with male factor.

Hemangiopericytoma is a rare mesenchymal neoplasm, accounting for about 1% of vascular tumor. Hemangiopericytoma is known to be derived from the vascular pericyte and occurs most commonly lower extremities, pelvis and retroperitoneum. Surgical radical excision is the treatment of choice. Because of malignant features of hemangiopericytoma, long term and close follow-up is important. We report a case of successfully resected retroperitoneal hemangiopericytoma.

OBJECTIVE: To investigate the histologic features of the uterus and adnexae extirpated from gender identity disorder (GID) patients that received depot androgen injection. METHODS: We reviewed the histologic findings of the uterus and adnexae removed from sixteen GID patients, who had taken depot androgen injection for 5~168 months. RESULTS: Fourteen patients (87.5%) showed the atrophied epithelium of exocervix and all of 16 patients (100%) showed the atrophy of endometrium. Seven patients (43.7%) showed multiple cystic follicles in the ovarian cortex and 6 patients (37.5%), 3 patients (18.7%) showed corpus albicans and corpus luteum, respectively. CONCLUSIONS: Exogenous androgen induced atrophy of cervix and endometrium. This effect was more prominent in the endometrium. In addition, PCO-like histologic features were observed in the ovary.

5.Effect of Antenatal Corticosteroid and Antibiotics in Pregnancies Complicated by Premature Rupture of Membranes between 24 and 28 weeks of Gestation.
Journal of Korean Medical Science 2005;20(1):88-92
The aim of this study was to assess the effectiveness of active intervention with antenatal maternal corticosteroid and antibiotics therapy in infants delivered between 24 and 28 weeks of gestation after premature rupture of membrane. This retrospective study included pregnant women complicated by preterm delivery at the Dong-A University Hospital from 1998 to 2002. Patients were divided into labor induction group 1 (n=20), observation group 2 (n=19), and medication group 3 (n=20). We evaluated the effects of prolongation of pregnancy and intervention with maternal corticosteroids and antibiotics therapy on perinatal and neonatal outcomes. Each group did not have a significant difference (p<0.05) in neonatal outcomes, such as respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, retinopathy of prematurity, pneumonia, bronchopulmonary dysplasia, and sepsis. The mean latency period was 4.7 days and 7.6 days in groups 2 and 3, respectively. Therefore, this study was unable to demonstrate any beneficial effects of corticosteroids in improving neonatal outcomes and prolongation of the latency period with antibiotics.

Korean Journal of Obstetrics and Gynecology 2009;52(6):631-635
OBJECTIVE: To investigate the relationship between serum dehydroepiandrosterone sulfate (DHEAS) or free testosterone (FT) levels and aging. METHODS:One hundred and thirty one women without androgen excess symptoms such as oligomenorrhea or amenorrhea or hirsutism were recruited for measuring serum DHEAS, FT levels by radioimmunoassay. A P-value <0.05 was considered to be significant statistically. RESULTS: The levels of DHEAS were 211.39+/-33.01 microg/dL (twenties, n=10), 127.99+/-11.79 microg/dL (thirties, n=31), 94.30+/-7.49 microg/dL (forties, n=57) and 71.79+/-5.71 microg/dL (over fifties, n=33) respectively (mean+/-SE, P<0.001). The levels of FT were 3.98+/-0.94 pg/ml (twenties, n=10), 3.37+/-0.47 pg/mL (thirties, n=31), 2.68+/-0.30 pg/mL (forties, n=57) and 1.97+/-0.28 pg/mL (fifties, n=33) respectively (mean+/-SE, P=0.030). Mean value declining of DHEAS (r=-0.48865, P<0.0001) was bigger than those of FT (r=-0.29334, P<0.0007). CONCLUSION: Both DHEAS and FT levels decline with age and DHEAS decreases more steeply than FT.

Korean Journal of Obstetrics and Gynecology 2010;53(10):915-920
OBJECTIVE: To investigate how many leiomyoma patients are exposed to bisphenol-A (BPA) and whether the serum concentration of BPA is related to leiomyoma growth. METHODS: Total 131 patients were recruited for measuring BPA. Initially, leiomyoma patients were divided into three groups, mild (n=38), moderate (n=33), and severe (n=30) according to the size of the leiomyomas. The control (n=30) group was defined as having no leiomyomas. The identification and diameter measurements of leiomyomas was performed by transvaginal ultrasonography. Serum BPA concentrations were measured by enzyme linked immunosorbent assay. RESULTS: BPA was detected in 83.9% out of 131 samples totally, and 83.1% out of 101 leiomyoma patients. In detail, the detection rates of serum BPA were 86.7% in control group, 71.1% in mild group, 84.9% in moderate group, and 96.7% in severe group. The mean BPA concentrations in the control group was 0.557+/-0.086 ng/mL and those in the leiomyoma groups were 0.273+/-0.052 ng/mL (mild), 0.336+/-0.063 ng/mL (moderate), and 0.636+/-0.075 ng/mL (severe) (P=0.0003). Values are mean+/-standard error. Conclusions: The detection rate of serum BPA in control and leiomyoma groups were 86.7% and 83.1% respectively. However, there was no statistical significance of serum BPA concentrations between control and leiomyoma groups. To verify the effect of BPA on the leiomyoma growth, close and sequential monitoring for the person who have exposure risk is recommended.

Traditionally, pathologists microscopically examine tissue sections to detect pathological lesions; the many slides that must be evaluated impose severe work burdens. Also, diagnostic accuracy varies by pathologist training and experience; better diagnostic tools are required. Given the rapid development of computer vision, automated deep learning is now used to classify microscopic images, including medical images. Here, we used a Inception-v3 deep learning model to detect mouse lung metastatic tumors via whole slide imaging (WSI); we cropped the images to 151 by 151 pixels. The images were divided into training (53.8%) and test (46.2%) sets (21,017 and 18,016 images, respectively). When images from lung tissue containing tumor tissues were evaluated, the model accuracy was 98.76%. When images from normal lung tissue were evaluated, the model accuracy (“no tumor”) was 99.87%. Thus, the deep learning model distinguished metastatic lesions from normal lung tissue. Our approach will allow the rapid and accurate analysis of various tissues.

Cushing's syndrome in pregnant women is rare and difficult to be diagnosed because of the syndrome's association with oligomenorrhea or amenorrhea and the changes in cortisol metabolism during normal pregnancy. Cushing syndrome in pregnancy is usually confused with complicated pregnancy, such as preeclampsia or gestational diabetes, and its rarity leads to a low degree of clinical suspicion, often delaying diagnosis. We experienced a case of Cushing's syndrome in pregnancy, which had been considered as the severe preeclampsia and gestational diabetes due to uncontrolled hypertension and hyperglycemia. The pregnancy was terminated with an emergency cesarean operation at 30 weeks of gestation because of severe preeclampsia. In consequence of the evaluation about the Cushing's syndrome after delivery, the adrenal cortical adenoma of right adrenal gland was diagnosed and laparoscopic adrenalectomy was performed.
