PurposeTo evaluate the efficacy of the use of oral Prednisolone and heparin versus the use of heparin alone in treatment of patients with unexplained recurrent miscarriage.MethodologyThe study was a double-blind placebo randomized control trial conducted on 160 patients with unexplained recurrent miscarriage. Patients recruited were randomized into two groups. The first group received oral Prednisolone in addition to low dose aspirin and heparin, while the other group received a placebo in addition to low dose aspirin and heparin. A peripheral venous blood sample was taken from all included patients before starting treatment and collected in heparinized tubes. Natural Killer (NK) cells were checked in each sample and then re-checked in another sample at 20 weeks of gestation.ResultsWe found that in the prednisolone group, 70.3 % of women had successful outcome (defined as an ongoing pregnancy beyond 20 weeks gestation), while 29.7 % miscarried before this gestation. On the contrary, among women in the placebo group, 9.2 % had successful outcome while 90.8 % miscarried before 20 weeks, which was statistically significant. On the other hand, we found that there were no significant paired differences between initial serum levels of the NK cells markers CD16 and CD56 and their levels at 20 weeks gestation in both groups.ConclusionThe addition of prednisolone to heparin and low dose aspirin might be beneficial in patients with unexplained recurrent miscarriage, and this effect might be due to a suppressive effect of steroids on the peripheral CD16 NK cells concentration.

Aim: The aim of this study was to evaluate the volume of blood loss, wound incision time and wound complication according to use of scalpel or electrosurgery during the creation of transverse abdominal incisions during repeated cesarean section (CS). Material and Methods: A randomized controlled trial was carried out at Ain Shams University Maternity Hospital. We recruited 130 women with a history of one previous CS at the time of their planned lower-segment CS. Participants were randomized to anterior abdominal wall opening from subcutaneous tissue till the peritoneum by either the use of scalpel with disposable blade (No. 22) or diathermy using the standard diathermy pen electrode. The main outcome measures were the volume of blood loss from skin incision to the end of the peritoneal incision, the operative time and wound complication. Results: We observed a highly significant difference between the two groups in blood loss (median [interquartile range], 11 [8-15.25] g for the diathermy group vs 20 [18-23] g for the scalpel group, P < 0.001) and skin-to-peritoneum incision time (median [interquartile range], 7 [5-7.25] min for the diathermy group vs 10 [7-11] min for the scalpel group, P < 0.001). The postoperative pain was less in the diathermy group but wound complications showed no statistical difference. Conclusion: The use of diathermy in the opening of anterior abdominal wall during CS decreases blood loss and operative time but has no impact on postoperative pain or wound complications.
