Heterotopic pregnancy in a natural cycle is rare case. This case occurs by one out of 30,000 cases of pregnancies. It is quite difficult to diagnose a heterotopic pregnancy clinically. But, recently, the availability of high-resolution sonography has improved the preoperative diagnosis rate. We present a case of spontaneous heterotopic pregnancy which was diagnosed pre-operatively by transvaginal ultrasound.

Uterine arterial pseudoaneurysm is a very rare condition usually associated with postpartum hemorrhage. It almost never occurs after cervical conization; however, since ruptured pseudoaneurysm could be life threatening, we should consider the possibility of vascular injury such as pseudoaneurysm when we find a patient with vaginal bleeding after the process of surgical operation. Emergency arterial embolization is a well established therapeutic option to control the ruptured pseudoaneurysm. This is a case report of uterine arterial pseudoaneurysm causing intra-abdominal bleeding followed by cervical conization, which was successfully treated by uterine artery embolization.

Carcinosarcomas of the uterine cervix are extremely rare. Cervical carcinosarcoma can be characterized by having two different origins: the Mullerian ducts and the mesonephric duct remnants. A 53-year-old Korean woman was admitted to the hospital because of pelvic mass detected on computed tomography scan done at private clinic. A Radical hysterectomy with bilateral salpingooophorectomy and pelvic lymphadenectomy was carried out upon a diagnosis of stage IB2 cervical sarcoma. Immunohistochemically, the epithelial component was positive for pancytokeratin and estrogen receptor, but negative for CD 10 and carletinin. The mesenchymal component was positive for vimentin. The histopathologic diagnosis was a carcinosarcoma of the uterine cervix arising from Mullerian ducts. She underwent chemotherapy. She developed systemic recurrence seven months after operation and died of disease. The origin of cervical carcinosarcoma needs to be verified and immunohistochemical studies using mesonephric marker (CD 10, carletinin, and estrogen receptor) is helpful.

Peritoneal origin serous papillary carcinoma is an uncommon primary malignancy occurring in the abdominal or pelvic peritoneum lining. It is characterized by peritoneal carcinomatosis with massive ascites, uninvolved or minimally involved ovary, and is histologically indistinguishable from ovarian serous tumors. Better recognition of this phenomenon in recent years has contributed to an increasing diagnostic frequency. We describe a rare case of peritoneal origin serous papillary carcinoma with unusual clinical presentations involving a solitary primary tumor originating from the peritoneal lining of the sigmoid colonal mesentery, without pelvic lymph node involvement or distant metastasis. Because of the location and morphological similarity, it was misdiagnosed as an ovarian malignancy. We aim to assist in the diagnosis of this disease with the following case report, thereby improving the management of patients with this condition.

OBJECTIVE: The aim of this study was to compare the surgical outcomes of single-port access (SPA) and conventional multi-port access total laparoscopic hysterectomies (TLH) among patients with very large uteri (500 g or more). METHODS: Fifty consecutive patients who received TLH for large uterine myomas and/or adenomyoses weighing 500 g or more between February 2009 and December 2012 were retrospectively reviewed. SPA and conventional TLH were each performed in 25 patients. Surgical outcomes, including operation time, estimated blood loss, postoperative hemoglobin change, postoperative hospital stay, postoperative pain, and perioperative complications, were compared between the two groups. RESULTS: There were no significant demographic differences between the two groups. All operations were completed laparoscopically with no conversion to laparotomy. Total operation time, uterus weight, estimated blood loss, and postoperative hemoglobin change did not significantly differ between the two groups. Postoperative hospital stay was significantly shorter for the SPA-TLH group compared to that of the conventional TLH group (median [range], 3 [2.0-6.0] vs. 4 [3-7] days; P=0.004]. There were no inter-group differences in postoperative pain at 6, 24, and 72 hours after surgery. There was only one complicated case in each group. CONCLUSION: SPA-TLH in patients with large uteri weighing 500 g or more is as feasible as conventional TLH. SPA-TLH is associated with shorter hospital stays compared to that of conventional TLH.

OBJECTIVE: The study aimed to evaluate the feasibility and reproducibility of measuring phospholipase C zeta (PLCzeta) using immunostaining in human sperm and to investigate the relationship between PLCzeta immunoreactivity and DNA fragmentation and oxidation in human sperm. METHODS: Semen samples were obtained from participants (n=44) and processed by the conventional swim-up method. Sperm concentration, motility, normal form by strict morphology, DNA fragmentation index assessed by terminal deoxynucleotidyl transferase dUTP nick end labeling method and immunofluorescent expression for 8-hydroxy-2'-deoxyguanosine (8-OHdG) and PLCzeta were assessed. RESULTS: When duplicate PLCzeta tests were performed on two sperm samples from each of the 44 participants, similar results were obtained (74.1+/-9.4% vs. 75.4+/-9.7%). Two measurements of PLCzeta were found to be highly correlated with each other (r=0.759, P<0.001). Immunoreactivity of PLCzeta was not associated with donor's age, sperm concentration, motility, and the percentage of normal form as well as DNA fragmentation index. However, immunoreactivity of PLCzeta showed a significant negative relationship with 8-OHdG immunoreactivity (r=-0.404, P=0.009). CONCLUSION: Measurement of PLCzeta by immunostaining is feasible and reproducible. Lower expression of PLCzeta in human sperm may be associated with higher sperm DNA oxidation status.

OBJECTIVE: To analyze the diagnostic profiles and treatment outcomes of patients with thoracic endometriosis at a university hospital. METHODS: A retrospective review of medical records was performed for patients diagnosed with thoracic endometriosis at Gangnam Severance Hospital, Yonsei University College of Medicine, between January 2007 and January 2014. RESULTS: Fifteen patients (median age, 35 years; range, 23-48 years) were evaluated. Patients presented with catamenial hemoptysis (n=8), or catamenial pneumothorax (n=7). Patients with catamenial pneumothorax were significantly older than those presenting with hemoptysis (P=0.0002). Only 3 patients (20%) had coexisting pelvic endometriosis. All patients underwent chest computed tomography; lesions were shown to predominantly affect the right lung (right lung, n=13, 86.7%; left lung, n=2, 13.3%), and were mainly distributed on the right upper lobe (n=9, 60%). Ten patients underwent video-assisted thoracoscopic surgery, and 1 patient underwent a thoracotomy. Intraoperatively, endometriosis-specific findings were observed in 8/11 patients (72.7%); a further 5/11 patients (45.4%) had histologically detectable endometriosis. Over the follow-up period (mean, 18.4 months; range, 2-65 months) 5/15 patients (33%) had clinical signs of recurrence. Recurrence was not detected in any of the 5 catamenial pneumothorax patients that received adjuvant hormonal therapy after surgery. CONCLUSION: The diagnosis and management of thoracic endometriosis requires a multidisciplinary approach, based upon skillful differential diagnosis, and involving careful gynecologic evaluation and assessment of the cyclicity of pulmonary symptoms. Imaging findings are non-specific, though there may be laterality towards the right lung. Since symptom recurrence is more common in those with presenting with pneumothorax, post-operative adjuvant medical therapy is recommended.

OBJECTIVE: To compare the laboratory outcomes of intracytoplasmic sperm injection (ICSI) and conventional insemination using sibling oocytes in poor prognosis IVF cycles where ICSI is not indicated. METHODS: Couples undergoing IVF with following conditions were enrolled: history of more than 3 years of unexplained infertility, history of > or =3 failed intrauterine insemination, leukocytospermia or wide variation in semen analysis, poor oocyte quality, or > or =50% of embryos had poor quality in previous IVF cycle(s). Couples with severe male factor requiring ICSI were excluded. Oocytes were randomly assigned to the conventional insemination (conventional group) or ICSI (ICSI group). Fertilization rate (FR), total fertilization failure, and embryonic development at day 3 and day 5 were assessed. RESULTS: A total of 309 mature oocytes from 37 IVF cycles (32 couples) were obtained: 161 were assigned to conventional group and 148 to ICSI group. FR was significantly higher in the ICSI group compared to the conventional group (90.5% vs. 72.7%, P<0.001). Total fertilization failure occurred in only one cycle in conventional group. On day 3, the percentage of cleavage stage embryos was higher in ICSI group however the difference was marginally significant (P=0.055). In 11 cycles in which day 5 culture was attempted, the percentage of blastocyst (per cleaved embryo) was significantly higher in the ICSI group than the conventional group (55.9% vs. 25.9%, P=0.029). CONCLUSION: Higher FR and more blastocyst could be achieved by ICSI in specific circumstances. Fertilization method can be tailored accordingly to improve IVF outcomes.

OBJECTIVE: This study was to identify small inhibitory RNAs (siRNAs) that are effective in inhibiting growth of cervical cancer cell lines harboring human papilloma virus (HPV) and to examine how siRNAs interact with interferon beta (IFN-beta) and thimerosal. METHODS: The HPV18-positive HeLa and C-4I cell lines were used. Four types of siRNAs were designed according to their target (both E6 and E7 vs. E6 only) and sizes (21- vs. 27-nucleotides); Ex-18E6/21, Ex-18E6/27, Sp-18E6/21, and Sp-18E6/27. Each siRNA-transfected cells were cultured with or without IFN-b and thimerosal and their viability was measured. RESULTS: The viabilities of HPV18-positive tumor cells were reduced by 21- and 27-nucleotide siRNAs in proportion to the siRNA concentrations. Of the two types of siRNAs, the 27-nucleotide siRNA constructs showed greater inhibitory efficacy. Sp-18E6 siRNAs, which selectively downregulates E6 protein only, were more effective than the E6- and E7-targeting Ex-18E6 siRNAs. siRNAs and IFN-beta showed the synergistic effect to inhibit HeLa cell survival and the effect was proportional to both siRNA and IFN-beta concentrations. Thimerosal in the presence of siRNA exerted a dose-dependent inhibition of C-4I cell survival. Finally, co-treatment with siRNA, IFN-beta, and thimerosal induced the most profound decrease in the viability of both cell lines. CONCLUSION: Long (27-nucleotides) siRNAs targeting E6-E7 mRNAs effectively reduce the viability of HPV18-positive cervical cancer cells and show the synergistic effect in combination with IFN-b and thimerosal. It is necessary to find the rational design of siRNAs and effective co-factors to eradicate particular cervical cancer.

OBJECTIVE: This study aimed to examine clinical practice patterns in the management of pregnant women admitted with threatened preterm labor (TPL) in Korea. METHODS: Data from women admitted with a diagnosis of TPL were collected from 22 hospitals. TPL was defined as regular uterine contractions with or without other symptoms such as pelvic pressure, backache, increased vaginal discharge, menstrual-like cramps, bleeding/show and cervical changes. Data on general patient information, clinical characteristics at admission, use of tocolytics, antibiotics, and corticosteroids, and pregnancy outcomes were collected using an online data collections system. RESULTS: A total of 947 women with TPL were enrolled. First-line tocolysis was administered to 822 (86.8%) patients. As a first-line tocolysis, beta-agonists were used most frequently (510/822, 62.0%), followed by magnesium sulfate (183/822, 22.3%), calcium channel blockers (91/822, 11.1%), and atosiban (38/822, 4.6%). Of the 822 women with first-line tocolysis, second-line tocolysis were required in 364 (44.3%). Of 364 with second-line, 199 had third-line tocolysis (37.4%). Antibiotics were administered to 29.9% of patients (284/947) with single (215, 22.7%), dual (26, 2.7%), and triple combinations (43, 4.5%). Corticosteroids were administered to 420 (44.4%) patients. Betamethasone was administered to 298 patients (71.0%), and dexamethasone was administered to 122 patients (29.0%). CONCLUSION: Practice patterns in the management of TPL in Korea were quite various. It is needed to develop standardized practice guidelines for TPL management.
