Aim: In the present study, we aimed to compare the effects of cetrorelix and leuprolide on endometriosis., Methods: This randomized, placebo-controlled, single-blind, experimental study was performed on 45 Wistar adult female rats in the Experimental Surgery Laboratory at Ondokuz Mayis University. After the peritoneal implantation of endometrial tissue, rats were randomized to three equal intervention groups: (i) control group, (ii) leuprolide group, and (iii) cetrorelix group. Six weeks later, following implant volume measurements (volume-1) by performing a second laparotomy, saline (0.1 cc/rat) was administered subcutaneously to the control group once a week, leuprolide (0.075 mg/kg) subcutaneously to the leuprolide group twice at 4-week intervals and cetrorelix (0.001 mg/rat/day) subcutaneously to the cetrorelix group for 8 weeks. At the end of the treatment, by performing a third laparotomy, implant volumes were remeasured (volume-2) and implants were totally excised for histopathological examination. The volume-1 and volume-2 values within the groups, and stromal and glandular tissue scores between the groups were compared., Results: In both the leuprolide group and the cetrorelix group, volume-2 as compared to volume-1 had significantly reduced (P < 0.01, P < 0.01 respectively), while there was no significant volume change in the control group (P > 0.05). In this group, when compared with the control group, glandular and stromal tissues had significantly lessened (P < 0.01, P < 0.01 respectively)., Conclusion: Leuprolide and cetrorelix were found to have similar efficacy in the regression of both the size and the histological structure of experimental endometriotic implants.

Aim: This prospective, single-blind and controlled clinical study aimed to research if CA-125 levels could be a useful test in the differential diagnosis of intact and ruptured tubal ectopic pregnancy., Methods: Sixty-five women with tubal ectopic pregnancy of 5-10 weeks' duration (27 women with ruptured tubal ectopic pregnancy [REP] and 38 women with unruptured tubal ectopic pregnancy [UREP]) and 65 women with normal intrauterine pregnancy (NIUP) of the same gestational age were studied prospectively. Serum CA-125 levels were measured in all women and these levels were compared among the REP, UREP, and NIUP groups., Results: The mean CA-125 levels didn't show any significant difference between the REP and NIUP groups (P > 0.05). The mean CA-125 levels of these two groups were higher than that in the UREP group (P < 0.01, P < 0.001, respectively). The dispersion ratios of the CA-125 levels had a statistically significant difference between the REP and UREP groups (chi(2): 42.44, P < 0.0001). CA-125 levels weren't correlated with gestational weeks in the REP and UREP groups (r: 0.005, P > 0.05; r: 0.008, P > 0.05, respectively)., Conclusion: In intact tubal ectopic pregnancies, expectant or managed with medical treatment, the increase of CA-125 levels in the serial measurements could be a supplementary test for an early diagnosis of tubal rupture.

In this abdominal pregnancy, the dead fetus was delivered through an abdominal incision at the 36th gestational week. The placenta invaded the small intestine and the omentum was left in situ. The placental degeneration was monitored using serial serum beta-human chorionic gonadotropin values. In certain periods, the follow up of the placental regression was carried out using the Cavalieri method with abdominal ultrasound. It was seen that the placental volume had decreased by 83% at the end of 1 year. To the best of our knowledge, this is the first time this method has been used for this purpose.
