Objective: To compare the efficacy and side effects of three regimens of intravaginal misoprostol for second-trimester abortion., Methods: A total of 118 women requiring second-trimester pregnancy termination were randomly assigned to one of three treatment groups: 400 microg 3-hourly in group A (n = 39), 600 microg 6-hourly in group B (n = 39), and 800 microg 12-hourly in group C (n = 40). Misoprostol tablets moistened with 3 ml of 5% acetic acid were placed into the posterior vaginal fornix., Results: The median induction-abortion times in groups A (8 h [range: 3-64]) and B (9 h [4-81]) were significantly shorter (p < 0.01 and p < 0.05, respectively) than in group C (12.5 [3-72]). Moreover, expulsion rates within 24 hours in groups A (92.3%) and B (92.3%) were significantly higher (p < 0.05 in both cases) than that of group C (75%). Expulsion rate within 48 hours, number of tablets used, number of patients with retained placenta and side effects did not differ between groups., Conclusions: Misoprostol moistened with acetic acid is effective for second-trimester pregnancy termination when given vaginally 3-hourly, 6-hourly or 12-hourly. The former two regimens are significantly more effective than the latter.

Objective: The aim of this randomized prospective study was to compare efficacy and side effects of saline moistened misoprostol with dry misoprostol, administered 800 mug intravaginally every 6 h up to a maximum of 3 doses in 24 h for second trimester pregnancy termination., Materials and Methods: A total of 81 women seeking termination of second trimester pregnancy (55 fetal death, 17 fetal structural anomaly, 5 chromosomal abnormality, 4 other reasons) were randomly assigned to one of two treatment groups: (1) intravaginal non-moistened (dry) misoprostol in group A (n = 40) or (2) misoprostol moistened with 3 ml of saline in group B (n = 41)., Results: All of the patients in either group aborted within 48 h (100% success rate). Delivery was achieved in a median (interquartile range) of 13 (40) h with the group A protocol and 12 (36) h with the group B protocol (P = 0.652). Delivery with first dose, delivery within 12 h and delivery within 24 h were similar (P > 0.05) in group B (34.1, 87.5 and 60%, respectively) and group A (25, 82.9, 46.3, respectively). Both treatment regimens were tolerable and with similar side effects., Conclusion: Misoprostol moistened with saline was not more effective than dry misoprostol for second trimester pregnancy termination.

Objective: To evaluate the effect of misoprostol on bone mineral density in postmenopausal women., Materials and Methods: The study was performed in a randomized controlled prospective manner in 90 women with menopause at Süleymaniye Maternity and Women's Diseases Teaching and Research Hospital between January and December 2003. Cases were divided into three groups each consisting of 30 women who were in menopause for at least 1 year and had t-scores less than -1 by dual energy X-ray densitometry (DEXA). Group I was treated with misoprostol and calcium, Group II received tibolone and calcium and Group III was given calcium only and considered as control group. In all patients, bone mineral density in L1-L4 vertebrae, femur neck and Ward triangle were measured by DEXA and t and z scores were calculated., Results: All groups were similar demographically. Bone mineral density in L1-L4 vertebrae, femur neck and Ward triangle in the group treated with misoprostol, increased by 5, 8.1 and 3.6%, respectively. In the tibolone group, bone mineral density in L1-L4 vertebrae, femur neck and Ward triangle increased by 8.3, 5.3 and 7.8%, respectively. There was not a significant difference in t and z-scores and bone mineral density measurements between misoprostol and tibolon groups., Conclusion: Misoprostol may be an alternative treatment for patients with osteopenia and osteoporosis who are not suitable for hormone replacement therapy.

Background: This study was conducted to evaluate the efficacy and side effects of a new regimen of 800 microg misoprostol administered intravaginally every 6 h up to a maximum of three doses in 24 h for second trimester pregnancy termination., Methods: A total of 66 women seeking termination of second trimester pregnancy (30 fetal structural anomaly, six chromosomal abnormality and 30 fetal death) were randomly assigned to one of two treatment groups: (i) intravaginal misoprostol moistened with 3 ml of 5% acetic acid in group A (n = 33); or (ii) intravaginal misoprostol moistened with 3 ml of saline in group B (n = 33)., Results: The overall median (range) induction-abortion interval was 10 h (2-46) [10 h (4-35) in 36 live fetuses and 9 h (2-46) in 30 dead fetuses, P = 0.515]. All of the patients in both groups aborted within 48 h (100% success rate). The median (range) induction-abortion interval revealed a significantly faster delivery time (P < 0.001) in group A [8 h (2-24)] than in group B [14 h (3-46)]., Conclusions: This new regimen of 800 microg of vaginal misoprostol every 6 h for a maximum of three doses in 24 h was an effective alternative method for second trimester abortion. In addition, misoprostol moistened with acetic acid was significantly more effective than misoprostol moistened with saline.
