A case of vulvar hemangiopericytoma / 대한산부인과학회지

Hemangiopericytoma is a rare vascular tumor arising from the adventitial pericytes of the small capillaries. Hemangiopericytomas primarily affect adults and are rare in infants and children. Both genders are equally affected. The most common anatomic locations for hemangiopericytoma are the lower extremity, axilla, pelvis, retroperitoneum, and head and neck. Surgical resection is the treatment of choice for hemangiopericytoma. The occurrence of this tumor in the vulva is rare, and to our knowledge we report the first case of a hemangiopericytoma arising from the vulva in Korea

Prognosis of pregnancy and perinatal outcomes in epileptic pregnant women used antiepileptic drugs / 대한산부인과학회지

OBJECTIVE: The purpose of this study was to investigate the prognosis of pregnancy and perinatal outcomes of epileptic women used antiepileptic drugs. METHODS: A retrospective analysis of 66 consecutive pregnancies of 41 epileptic women from January 1989 through December 2005 was performed. The maternal and perinatal outcomes of pregnancies with epilepsy were compared with those of 1,000 normal pregnancies of similar age and parity occurred during the same period. We also compared the perinatal outcomes regarding protocol of antiepileptic drugs (monotherapy vs polytherapy), existence of gestational seizure, and duration of epileptic history. Statistical analyses with chi-square test and t-test were performed. RESULTS: In our comparison study between epilepsy and normal groups, with the exception of primigravida (43.8% vs 31.8%, p=0.009), induction of labor (43.1% vs 22.1%, p=0.001) and major congenital malformation (6.9% vs 2.0%, p=0.015), no other significant differences regarding maternal and perinatal outcomes were noted between two groups. There were no different obstetrical outcomes between monotherapy and polytherapy groups. In epileptic women with gestational seizure, the rate of fetal distress (20.0% vs 2.3%, p=0.02) was significantly increased. In longer epileptic history (> or =10 years), the rates of preterm birth, low birth weight, and major congenital malformation were increased, but there was no statistical significance. CONCLUSION: There are no increased maternal and perinatal complications in epileptic women used antiepileptic drugs, except for major congenital malformation.

A clinical analysis of uterine myoma / 대한산부인과학회지

From January 1998 to December 2002, 3,259 cases of uterine myoma were treated at the department of Obstetrics and Gynecology, Chunbuk National University Hospital. A clinico-stastical study of uterine myoma was perfomed to analyse the clinical characteristics. The results were as follows. 1. The incidence of uterine myoma was 9.8%. 2. The most frequent age group was 40 to 49 years, and the mean age was 44.6 years. 3. The average parity was 2.29, the infertility was 163 cases (5.0%), while the primary infertility, 2.4%, the secondary, 2.6% respectively. 4. The most frequent chief complaint was pain which was observed in 2,648 cases (81.2%), abnormal bleeding in 1,775 cases (53.8%). dizziness in 270 cases (8.3%). 5. The corporeal myomas were observed in 2,879 cases (95.9%). Intramural type was observed in 1,687 cases (58.2%), subserous in 529 cases (18.2%), submucous in 191 cases (6.5%), mixed type in 483 cases (17.0%). 6. The mean value of preoperative hemoglobin was 11.1 gm/dL, and the anemia (Hb<10.0 gm/dL) was observed in 481 cases (11.7%). Transfusion was necessary in 215 cases (6.5%). 7. The mean weight of the uterine myoma operated was 335.0 gm. 8. The secondary change of myoma was found in 54 cases (1.7%) and hyaline degeneration was the most common (0.7%). 9. The most common associated condition was chronic cervicitis, which was observed in 784 cases (24.1%). 10. The gynecologic surgery were performed in 1,456 cases (44.7%), medical therapy in 25 cases (0.8%), observation in 1,792 cases (55.0%). 11. Total abdominal hysterectomy was performed in 607 cases (41.7%), total abdominal hysterectomy with unilateral adnexectomy in 115 cases (7.9%), total abdominal hysterectomy with both adnexectomy in 164 cases (11.3%), subtotal hysterectomy in 304 cases (20.9%), myomectomy in 153 cases (10.5%), total laparoscopic hysterectomy in 103 cases (7.0%), laparoscopy assisted vaginal hysterectomy in 8 cases (0.5%), diagnostic laparoscopy in 2 cases (0.1%) respectively. 12. The postoperative complication were found in 113 cases (3.5%) and the wound infection was the most common (1.6%). 13. The mean period of hospitalization was 8 days, and the period less than 10 days in 1,177 cases (80.9%).

A case of heterotopic pregnancy in a natural cycle: ultrasound diagnosis / 대한산부인과학회잡지

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.

Comparative study on Development of Mouse Embryos in Conventional Medium versus Vero Cell Coculture / 대한산부인과학회잡지

OBJECTIVE: To evaluate mouse embryos development in conventional medium IVF-20 versus vero cell coculture. METHODS: Female ICR mice aged 6 to 8 weeks, were stimulated with 5IU PMSG and 48 hours later were injected 5IU of hCG, then female and male mice were mated. At 48 hour post-hCG injection, oviducts were dissected out and 2-cell embryos were flushed. The 2-cell embryos were cultured in IVF-20 media or media containing vero cell (African green monkey kidney epithelial cell lines) for 120 hours. Coculture techniques have been applied in mouse 2-cell embryos culture used vero cell lines. RESULTS: 1. After 48 hours culture, 60.7% and 55.7% of 2 cell embryos developed to 4 cell and morulae stage, respectively, in IVF-20 culture medium, but significantly less embryos developed to 4 cell (47.6%, p<0.05) and momlae (42.9%, p<0.05) in vero cell coculture. 2. After 72 hours culture, 51.6% of 2 cell embryos developed to blastocyst and expanded blastocyst in IVF-20 culture medium, but significantly less embryos developed to blastocyst and expanded blastocyst (25.9%, p<0.01) in vero cell coculture. 3. After 96 hours culture, 37.7% and 32.6% of 2 cell embryos similar developed to expanded blastocyst and hatching in IVF-20 culture medium and vero cell coculture, respectively. 4. After 120 hours culture, 36.9% and 37.4% of 2 cell embryos similar developed to expanded blastocyst and hatching in IVF-20 culture medium and vero cell coculture, respectively. CONCLUSION: There was no difference of embryo development rates between the two culture groups. IVF-20 medium alone gives a benefit to the viability of an embryo compared with a vero cell coculture.
