Evaluation of the level of total nitrate and nitrite concentration in vaginal secretion in cases with preterm labor and if it can be used as a predictor of premature delivery

Vaginal secretions were collected after informed consent from 80 pregnant women with gestational ages from 27 to 32 weeks. Samples were collected by thorough washing of the vagina with 5 ml sterile physiologic sodium chloride solution. Samples were stored at -40C until delivery of all studied pregnant women. The level of total nitrite and nitrate concentration in vaginal secretion of pregnant women who delivered before 37 completed weeks and in those with preterm premature rupture of membranes with subsequent preterm delivery were significantly higher than in those delivered at term

Serum determination of the level of iron, ferritin and transferrin in pregnant patients and their relation to preterm delivery

Seventy-five women presenting with preterm labor whose gestational age ranged from 26 to less than 37 weeks were chosen as the study group. Another 75 women were used as a control group [25 women whose gestational age ranged from 38 to 40 weeks presenting in labor and the other 50 women with gestational ages ranged from 27 to 37 weeks attending the antenatal clinic and were not in labor]. 5 ml venous bloods were withdrawn from the anti-cubital vein from each woman, 2 ml for hemoglobin and 3 ml for serum assay of iron, ferritin and transferring determinations. The results revealed that the concentration of serum ferritin was higher in preterm group and the differences were statistically significant. However, the differences between concentrations of serum iron and serum transferrin among these groups have no significance. In conclusion, the differences of serum iron and transferrin has no significant value in cases of preterm labor, hut the difference in serum ferritin has a good significant value in cases of preterm labor, thus elevation of serum ferritin in the second trimester can be used a predictor of early spontaneous preterm labor

Vascular and hormonal changes before and after laparoscopic ovarian electrocautery in patients with polycystic ovarian disease

Forty infertile patients with PCOD were enrolled in the study, they were undergone laparoscopic ovarian electrocautery. Before the operation, all cases were subjected to a good history with a thorough clinical examination together with transvaginal ultrasonic examination, hormonal profile [FSH, LH, prolactin and DHEA] in the early follicular phase and color Doppler of uterine and ovarian arteries with determination of pulsatility index [PI] were done to all patients. After operation hormonal profile was assessed one day, one month and three months after electrocautery, Doppler study of ovarian and uterine arteries, folliculometry for three consecutive cycles. As regard Doppler before drilling, flow velocity patterns of uterine and ovarian vessels showed high pulsatility index [PI], which showed gradual decrease along the three cycles after drilling. As regard, hormonal profile, FSH showed significant rise, while LH and LH/FSH ratio showed significant fall along the three cycles, DHEA showed no significant change one day after drilling, but significantly decreased one month and three months after drilling. On the other hand, prolactin showed no significant change
