We sought to compare maternal and neonatal risk factors in cases with previable premature rupture of membranes (pPPROM, between 14-24 weeks) for optimal counselling. Therefore, 192 pregnancies of 485 cases which met selection criteria and agreed to follow-up were retrospectively analysed. Mean gestational age at pPPROM was 20.45 weeks. Live births occurred in 171 cases, but 67 (39.2%) of them died in the neonatal period (neonatal death group) and 104 cases (60.8%) constituted surviving neonate group. Of the surviving neonates, 37 (33.7%) experienced at least one complication. Most seen maternal complications were chorioamnionitis (24.48%) and placental abruption (8.33%). Although amniotic fluid volume, length of pPPROM period, completing antibiotherapy and CRP values were significant, amniotic fluid volume and length of pPPROM showed also significance for multivariate regression analysis for maternal risk factors. Risk factors for birth were gestational age at pPPROM, gestational age at birth, new-born weight at birth, 1st and 5th minute Apgar scores, umbilical cord pH value and need for neonatal resuscitation. Furthermore, development of respiratory distress syndrome, necrotising enterocolitis, intraventricular haemorrhage and retinopathy of premature were additional risk factors for neonate. Of them, gestational age at birth, new-born weight at birth, respiratory distress syndrome and retinopathy of prematurity were also significant in multivariate regression analysis.

Background: We aimed to investigate the impact of adopting an uterine manipulator (UM) on the postoperative (VL) and female sexual function index (FSFI) in patients undergoing abdominal hysterectomy (AH) for benign gynecological disease. Materials and Methods: Hysterectomies were performed with the Richardson technique; two variations, a UM or digital guidance, in this technique were used during the colpotomy step. Subjects were randomized and allocated to either hysterectomy with UM guidance (study group) or conventional hysterectomy (control group). Pre- and postoperative VL and FSFI were recorded for each patient. Additionally, surgeons' and residents' satisfaction in locating the colpotomy site was also scored by the surgical team postoperatively. Results: There was a significant reduction in the VL (10.2 +/- 1.2 cm vs. 8.3 +/- 0.7 cm, p < 0.001) and FSFI score (21.0 +/- 4.1 to 17.1 +/- 3.6, p < 0.001) between the pre-operation stage and three months post-operation in the control group. However, no such significant changes were observed in the study group. Additionally, surgeons' and residents' satisfaction scores (SSS) for locating the colpotomy site were significantly higher in the study group as compared to the control group (p < 0.001). Conclusion: Our findings revealed that implementation of an UM in AH prevented unintended shortening of the postoperative VL and avoided a decline in the sexual function as compared to the standard AH procedure. These benefits were probably due to the precise determination of the colpotomy site that resulted from the use of UM in AH.

In organ or non-organ-specific autoimmune disorders, human ovary is usually the target of the autoimmune attack. We aimed to demonstrate the correlation between ovarian reserve and DM1, based on the view that women with type-1 diabetes mellitus (DM1) will have lower AMH levels secondary to poor glycemic control and autoimmune attacks. Ovarian functions of 42 patients diagnosed with DM1 who use insulin and 65 healthy volunteers were analyzed. Basal hormone and AMH levels were measured during the follicular phase. Fasting and postprandial blood glucose concentrations, HbA1c and C-peptide levels were evaluated. The mean antral follicle count (AFC) was significantly lower in DM1 patients than in healthy controls (p = .001). The AMH levels were lower in women with DM1 than in the controls (p = .001). The HbA1c values of DM1 patients, who formed the study group, was significantly higher than the control group. Ovarian reserve that is evaluated with serum AMH level is affected by poor glycemic control in type 1 diabetes. Due to the time of the autoimmune damage in the ovaries and the observable effects of this damage, more comprehensive and longer-term studies are needed to be conducted for the follow-up of reproductive abnormalities.

Background/aim: To investigate the risk of de novo stress urinary incontinence (SUI) occurrence in women who were treated for pelvic organ prolapse (POP) with sacrospinous ligament fixation (SSLF) in addition to vaginal hysterectomy (VAH) and antero-posterior colporrhaphy (CAP) over a 24-month follow-up period. Materials and methods: A prospective randomized study was designed. Women without occult or obvious SUI were randomized into either one of the study groups: Group 1: VAH + CAP, and Group 2: VAH + CAP + SSLF. Postoperatively, the patients were reevaluated for de novo SUI occurrence. Results: A total of 150 women were analyzed [G1 = VAH + CAP (n: 77) and G2 = VAH + CAP + SSLF (n: 73)]. Mean age, parity, body mass index, menopausal status, and preoperative POP degree, grade 1 and grade 2-3 cystocele and rectocele frequencies were similar between the 2 groups. During follow-up period, de novo SUI developed in 7 patients (9.1%) of Group 1, and in 6 patients (8.2%) of Group 2 (P > 0.05). In Groups 1 and 2, POP recurrence occurred in 5 (6.4%) vs. 1(1.3%) cases,respectively (P < 0.05). Conclusion: In patients undergoing surgery for POP, the addition of SSLF did not result in an increased rate of de novo SUI. Careful patient selection, and informing the patients about the risks and benefits of the planned surgical procedure are essential steps in each case of POP.
