The adjuvant effect of metformin and N-acetylcysteine to clomiphene citrate in induction of ovulation in patients with Polycystic Ovary Syndrome.

OBJECTIVES: To assess the adjuvant effect of metformin and N-acetylcysteine (NAC) to clomiphene citrate (CC) in induction of ovulation in Polycystic Ovary Syndrome (PCOS) patients. STUDY DESIGN: 120 women with PCOS were randomly divided into three equal groups: group I received CC only, group II received CC plus NAC and group III received CC plus metformin. RESULTS: There was a significant difference between group II and other two groups regarding average number of ovulatory follicles >18 mm (2.25 versus 1.75 and 1.89, respectively), but no significant difference between the three study groups regarding number of intermediate follicles 14-18 mm (4, 10 and 4, respectively). There was no significant difference between the three study groups regarding occurrence and laterality of ovulation, pregnancy rate per cycle but a significant difference between group II and other two groups regarding pregnancy rate per patient (20% versus 10% and 10%, respectively, p value 0.05). There was a highly statistically significant difference between group II and other two groups regarding peak endometrial thickness (7.3 ± 1.1 versus 5.4 ± 0.6 and 5.3 ± 0.6, respectively). CONCLUSIONS: NAC as an adjuvant to CC for induction of ovulation improves ovulation and pregnancy rates in PCOS patients with beneficial impacts on endometrial thickness.

Fetal middle cerebral and umbilical artery Doppler after 40 weeks gestational age.

OBJECTIVE: To determine the value of fetal Doppler indices named middle cerebral artery (MCA)-PI, umbilical artery (UA)-PI and MCA-PI/UA-PI ratio, and amniotic fluid volume assessment in pregnancies 280-294 d and their correlation with the mode of delivery and perinatal outcome. STUDY DESIGN: Prospective observational study conducted on 100 whose gestational age (GA) from 40 to 42 weeks. MCA and UA Doppler and MCA-PI/UA-PI ratio, amniotic fluid volume (AFV) were assessed. They were divided into two groups based on the presence or absence of adverse perinatal outcome. RESULTS: Women with adverse perinatal outcome showed lower MCA-PI (0.92 versus 1.29), MCA-PI:UA-PI ratio (1.04 versus 1.83), lower gestational age when assessed by ultrasound (37.82 versus 39.48 weeks), lower neonatal birth weight (2705 versus 3108 g), fetal biophysical profile (BPP) (4.55 versus 7.21) when compared to women with normal perinatal outcome. They also had higher cases with oligohydramnios (34 versus 5), and higher UA-PI (0.89 versus 0.72). CONCLUSION: Women with adverse neonatal outcome had higher UA-PI and lower MCA-PI, MCA-PI:UA-PI ratio, GA (by US), AFV, BPP, estimated fetal weight, neonatal birth weight when compared to those with normal perinatal outcome. Women with adverse neonatal outcome had a higher rate of cesarean section mostly due to fetal distress and induced VD due to oligohydraminos compared to the normal outcome group.
