A Case of Amnioreduction in Prolapsed Membranes After McDonald Cerclage / 대한산부인과학회잡지

Incompetent internal os of cervix is treated with McDonald or Shirodkar cerclage after 14 weeks of gestation. In rare case, after 20 weeks of gestation fetal membrane is bulging into vaginal cavity, but cerclage in that period is risk factor for preterm labor and preterm premature rupture of membranes. So many complications are reported in that period. So many experiences for reducing fetal membranes into uterine cavity were performed. We report a case of amnioreduction in prolapsed fetal membranes after McDonald cerclage, and delivered in 33 weeks of gestation with brief review of literature.

The Effects on Sperm Parameters and Membrane after Treatment with Progesteroneand/or Acetyl-L-Carnitine; Cryopreservation-Thawing / 대한불임학회지

OBJETIVE: To assess the effects of progesterone and acetyl-L-carnitine used after treated with IsolateR gradient before semen cryopreservation-thawing on sperm parameters and membrane integrity. MATERIALS AND METHODS: From April 2001 to July 2001, ten normal male partner of couples who were visited in vitro fertilization (IVF) clinics. the semens were treated with IsolateR gradient before cryopreservation, spermatozoa was incubated with progesterone (1, 5 and 10 micrometer), acetyl-L-carnitine (2.5, 5 and 10 micrometer), or both (progesterone, 1 micrometer; and acetyl-L-carnitine, 5 micrometer) for 30 min. RESULTS: There were no differences in sperm parameters and vital stain among isolate only treated group, progesterone (1, 5 and 10 micrometer), acetyl-L-carnitine (2.5, 5 and 10 micrometer) and both (progesterone, 1 micrometer; and acetyl-L-carnitine, 5 micrometer). But, in high concentration of acetyl-L-carnitine (10 micrometer) treated group, sperm parameters and vital stain were decreased. The statistical method was used ANOVA (Kruskal-Wallis test) and p value was <0.01. CONCLUSIONS: Neither progesterone nor acetyl-L-carnitine show to be protective effect on the cryodamage assessed by sperm parameters and vital stain (eosin-Y stain) in normal sperm. High concentration of acetyl-L-carnitine (10 micrometer), however, was harmful effect on cryoprevention.

A Case of Heterotropic Pregnancy After In Vitro Fertilization / 대한산부인과학회잡지

Heterotropic pregnancy is defined as coexistent intrauterine and ectopic pregnancy. The natural incidence is 1 per 30,000 pregnancies, but in case of ovulation induction and in vitro fertilization, it is 1 per 100 pregnancies. Heterotropic pregnancy is increased with pelvic inflammatory disease and the use of various ovulation induction method. Because heterotropic pregnancy is clinically difficult to early diagnosis, close monitoring of pregnancy is important to prevent a deleterious delay in the treatment of ectopic pregnancy, maternal morbidity, and fetal loss. We experienced a case of heterotropic pregnancy diagnosed by ultrasonography in a 32-year-old woman, who complained of vaginal spotting and low abdominal pain after in vitro fertilization and report the case with brief review of literature.
