ABSTRACT

OBJECTIVE: Oligohydramnios is defined as amniotic fluid index in ultrasonographic measurement is less than 5 percentile according to gestational age, the amniotic fluid volume is ≤ 5 cm, or if the single deepest dial is < 2 cm. The condition of oligohydramnios that not with fetal structural/chromosomal abnormalities, intrauterine growth retardation, intrauterine infection and maternal disease is described as isolated oligohydramnios (IO). The aim of this study is to examine whether oxidative stress and reactive oxygen species (ROS) have a place in the pathophysiology of IO. MATERIALS AND METHODS: In this prospective case-control study, a total of 126 participants were included. The patient group consisted of 65 patients who were diagnosed IO, and the control group consisted of 61 healthy normal pregnants. Native thiol (-SH), total thiol (-SH + -SS), dynamic disulfide (-SS), IMA values from maternal serum were measured and compared between groups. RESULTS: Maternal serum -SH and -SH + -SS values were significantly lower in the IO group than in the control group (409.47 ± 55.36 µmol/L vs. 437.40 ± 48.68 µmol/L, p = 0.03 and 457.40 ± 63.01 µmol/L vs. 484.59 ± 52.75 µmol/L, p = 0.01). In the IO group when -SS/-SH and -SS/-SH + -SS ratio was found to be statistically significantly higher than control group (5.84 ± 1.1 vs 5.41 ± 0.71, p = 0.01 and 5.2 ± 0.88 vs 4.8 ± 0.58, p = 0.01), -SH/-SH + -SS ratio was significantly lower (89.56 ± 1.7 vs 90.24 ± 1.16, p = 0.01). There was no significant difference in terms of -SS value (p = 0.66). IMA value was significantly higher in the IO group than control group (0.76 ± 0.10 ABSU vs 0.68 ± 0.06, p < 0.01). It is seen as a result of ROC analysis that -SH, -SH + -SS, -SS/-SH, -SS/-SH + -SS, -SH/-SH + -SS and IMA values have a diagnostic value for IO (p < 0.05). CONCLUSION: The thiol/disulfide balance shifted towards oxidative stress in IO compared to control group. So oxidative stress and ROS have a place in the pathophysiology of IO.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: Peritonisation of mesh during Abdominal sacrocolpopexy is generally advocated to prevent adhesions to the viscera; however, randomized clinical trials are lacking. In this study; we aimed to investigate whether the mesh peritonisation is clinically significant or not. MATERIAL METHOD: Thirty-four patients who were operated for the reason of pelvic organ prolapse were included in the study. Patients were divided into two groups by retrospective scanning from the files and surgical reports. Group 1 patients consisted of those who underwent peritonisation and group 2 patients consisted of those who did not in abdominal sacrocolpopexy. RESULTS: Operative time and the amount of blood lost were statistically less in the group 2. Postoperative pain and analgesic drug requirements were obviously higher in the group 1. Postoperative De novo dyspareunia and urinary urgency were higher in the group 1. There were no statistical differences between the groups in terms of other complications. CONCLUSION: We noticed that there was no difference between the patients who were peritonized and those who were not in terms of postoperative complications.

ABSTRACT

AIM: Oxidative stress and impaired antioxidative system are implicated in the development of many disease states including gynecological diseases. In the present study, we aimed to investigate the oxidative-antioxidative status in endometrium of patients diagnosed with benign gynecological disorders. METHODS: Samples of endometria and blood were obtained from 65 patients admitted to our center for abnormal uterine bleeding or postmenopausal bleeding. Endometrial biopsy was performed for the evaluation of histopathology and oxidative-antioxidative status in endometrial tissue. Based on histological examination, subjects were divided into groups as follows: normal controls (n=15); patients with endometrial polyps (n=20); patients with uterine myoma (n=10) patients with chronic endometritis (n=10), and patients with atrophic endometrium (n=10). Activities of superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR) and total antioxidant status (TOS), total oxidant status (TAS) were assessed. RESULTS: Compared to the normal controls, nonsignificant changes (decrease or increase) were detected in antioxidant enzyme activities, TAS and TOS in the examined groups. Additionally, between TAS and TOS, we also found a strong positive correlation in normal and chronic endomethritis groups and a moderate positive correlation uterine myoma, endometrial polyps and endometrial atrophy groups. CONCLUSION: Even though, our results do not allow to conclude how oxidative and antioxidative status are influenced in benign gynecological disorders, these findings may provide a basis for the further researches.

ABSTRACT

OBJECTIVE: To assess the authors' experiences in en bloc pelvic resection with concomitant rectosigmoid colectomy and primary anastomosis as a part of primary cytoreductive surgery for patients with advanced ovarian cancer. MATERIALS AND METHODS: Atotal of 22 patients with FIGO Stage IIB-IV epithelial ovarian cancer who underwent en bloc pelvic resection with anastomosis were retrospectively reviewed. Data analyses were carried out using SPSS 10.0 and descriptive statistics, Kaplan-Meier survival curves, and Log Rank (Mantel-Cox) test were used for statistical estimations. RESULTS: Median age was 58.8 years. FIGO stage distribution of the patients was; one (4.5%) IIB, three (13.7%) IIC, three (13.7%) IIIA, six (27.3%) IIIB, and nine (40.9%) IIIC. Median peritoneal cancer index (PCI) was 8 (range 5-22) and optimal cytoreduction was achieved in 18 patients (81.8%) of whom 13 (59.1%) had no macroscopic residual disease (complete cytoreduction). There was no perioperative mortality. A total of nine complications occurred in seven (31.8%) patients. Anastomotic leakage was observed in one (4.5%) patient. There was no re-laparotomy. Mean follow-up time was 60 months. There were 15 (68.2%) recurrences of which 12 (80%) presented in extra-pelvic localizations. Mean disease-free survival (DFS) and overall survival (OVS) were estimated as 43.6 and 50.5 months, respectively. Patients with complete cytoreduction had a better DFS (p = 0.006) and OVS (p = 0.003) than those with incomplete cytoreduction. CONCLUSION: En bloc pelvic resection, as a part of surgical cytoreduction, seems to be a safe and effective procedure in many patients with advanced ovarian cancer if required. Despite relatively high general complication rate, anastomosis-related morbidity of this procedure is low as 0.8%. Nevertheless, surgical plan and perioperative care should be personalized according to medical and surgical conditions of the patient.

ABSTRACT

Vascular access ports were developed to overcome many of the problems associated with limited peripheral access, combined with the need for frequent venipuncture, in oncology patients receiving long-term intensive therapy. In this study, we compared the effectivity and acceptability of vascular access port with conventional needle application together with complication rates in ovarian cancer patients. Advanced-stage ovarian carcinoma cases under chemotherapy treatment were equally randomized into two groups, implantable vascular access ports applied to one group (22 cases) and conventional vascular access applied to the other (38 cases) as a control group. Anteroposterior thoracic X-rays of implantable port-applied cases were taken before and after the application. Vortex reservoir ports (Horizon Medical Products, Inc., Manchester, GA) were used in the application to the subclavian vein. Classic peripheral venipuncture method (Medikit), Mediflon(trade mark) IV cannula with PTFE radiopaque catheter and injection valve, Eastern Medikit Ltd, Gurgaon, Haryana, India) was used in the control group. Vascular accesses of all cases were controlled just after the application, 12 h after the application, and during each drug or intravenous fluid application. Mean port insertion time was 26.3 min. Total port occlusion was observed in two of the port-applied cases (11.7%) and partial port occlusion was observed in five of the port-applied cases (29%). Heparin and saline combination was used in order to open the port tip, in five cases, two with total occlusion and three with partial occlusion. Infection was observed in only one case (5%) to whom appropriate therapy was given, and the port was taken out. Ports of two cases were also taken out because of skin dehiscence. No change in port tip position was observed in any of the cases. Total occlusion was observed in 16 of the 38 cases (42.1%) with conventional vascular access. In 12 cases (31.5%), a need arose to change the conventional vascular access. No vascular access was found in 13 of the 38 cases (34.2%). Application of reservoir ports especially to cases with advanced-stage carcinomas, under chemotherapeutic drug treatment, leads to minimal anxiety for the patient and his/her family and minimal risk of physical trauma to the patient with only one vascular access. Reservoir ports occlude or cause infection to a lesser extent than classic vascular access methods. Occlusion or infection rates of reservoir ports are statistically significant, lower than those of classic venipuncture.
