Reperfusion injury after detorsion of unilateral ovarian torsion in rabbits.

OBJECTIVE To determine if reperfusion injury takes place in ovarian tissue following the detorsion of the torsioned ovary. STUDY DESIGN Fifty-four New Zealand mature nonpregnant female rabbits were divided into six groups. One group served to determine the basal values of thiobarbituric acid reacting substance (TBARS) and another group was sham. In the third and fourth groups, ovarian torsions and subsequent oophorectomy were performed in 1 and 3h, respectively. In the fifth and sixth groups, detorsions were carried out after unilateral ovarian torsion lasting 1 and 3h, respectively, then oophorectomies of the detorsioned ovaries were performed 2h after detorsion. The level of TBARS in ovarian tissues was determined in all subjects. Statistical analysis was performed using analysis of variance and Duncans multiple range test. Differences were considered to be significant if P<0.05. RESULTS The levels of TBARS were not different in the basal and sham groups (P>0.05), while ovarian torsion caused significant increase in TBARS in the ovary (P<0.05), and detorsion caused a further significant increase in ovarian TBARS (P<0.05). CONCLUSION Reperfusion injury in ovarian tissue, following the detorsion after the torsion of the ovary lasting up to 3h was demonstrated biochemically in this study.

Antiphospholipid Antibodies in Eclamptic Women

Our purpose was to determine the prevalence of antiphospholipid antibodies (APA) in eclamptic women as well as the rates of intrauterine growth retardation (IUGR) and fetal death in APA-positive and -negative eclamptic women. Thirty-six eclamptic and 30 healthy pregnant women were enrolled in this study. APA in those groups were determined. The prevalences of IUGR and fetal death were determined in APA-positive and -negative eclamptic women. In the eclamptic group, APA were positive in 9 out of 36 patients (25%), where as only 2 out of 30 controls (6.7%) were positive (p < 0.05). Fetal death was encountered in 4 out of 9 (44.4%) APA-positive eclamptic women; this was a significantly larger proportion than that for APA-negative eclamptic women (1/27; p < 0.01). The rates of IUGR in APA-positive and -negative eclamptic women were not significantly different (p > 0.05). Similar conclusions about our results could also be made, when weakly positive anticardiolipin antibodies were regarded as negative in our study group and controls. Our study suggests that positive levels of APA in eclamptic women increase the risk for intrauterine fetal death.

Mature cystic teratoma in round ligament: case report

Our report describes an unusual presentation of mature cystic teratoma. In this case, 3 mature cystic teratomas were encountered during cesarean section, one in each round ligament and the other in the left ovary. According to the literature, round ligament is one of the rarest sites for the presentation of mature cystic teratoma.

Effects of coasting on the outcome of intracytoplasmic sperm injection-embryo transfer cycles

Objectives:  To determine the effects of ‘coasting’ on the outcome of controlled ovarian hyperstimulation (COH) and intracytoplasmic sperm injection–embryo transfer (ICSI–ET).

Laurence-Moon-Biedl Syndrome with Vaginal Atresia

A 15-year-old girl presented with the rare Laurence-Moon-Biedl syndrome, accompanied by vaginal atresia, and cervical dysgenesis. She was treated by hysterectomy and construction of a neovagina with bilateral pudendal thigh flaps. Two brothers and a sister (one of twins) were unaffected but the remaining brother also had the disease.

Do menopausal hot flashes have any significant effects on arterial blood gas measurements

OBJECTIVES To evaluate the effects of menopausal hot flashes on arterial blood gas measurements. METHODS Twelve postmenopausal women with frequent hot flashes were enrolled in this study. Blood samples from femoral artery were collected before and during menopausal hot flashes in each subject, and all blood samples were analyzed for pH, pCO2, pO2, HCO3 standard, total CO2, and base excess. Arterial blood gas parameters before and during menopausal hot flashes were compared statistically. RESULTS pH measurements decreased significantly during hot flashes (P < 0.05); although the difference was found to be statistically significant, the amount of decrease and the range in which the change took place led us to conclude that this change was clinically insignificant. Other parameters did not show any statistically significant differences between the preflash and flash measurements. CONCLUSIONS Our results indicate that menopausal hot flashes do not have any clinically significant effects on arterial blood gas measurements.
