Publication Open Access What Does the Data Show for Primary Ovarian Insufficiency?(2017-03-01T00:00:00Z) ÖZCAN, PINAR; Parasar, Parveen; Ficicioglu, Cem; ÖZCAN, PINARPrimary ovarian insufficiency (POI), a clinical syndrome, is defined by the exhaustion of the functional potential of ovaries prior to 40 years. The consequences of POI are potentially serious for long-term fertility, reproductive health, and general health because of early menopause. This article provides an updated review of different etiologic factors and pathogenic mechanisms that lie behind POI as well as current and novel strategies for the management of this challenging disease aimed at the primary prevention of the adverse effects of estrogen deficiency and infertility related to the early loss of ovarian function.Publication Open Access Vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC): technique and mean 20 months outcomes(2020-12-01T00:00:00Z) ŞEVKET, OSMAN; TAKMAZ, TAHA; Sevket, A. C.; TOPRAK, ALİ; ÖZCAN, PINAR; ŞEVKET, OSMAN; TAKMAZ, TAHA; TOPRAK, ALİ; ÖZCAN, PINARThe main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse. We retrospectively reviewed the results of twenty-three women with stage III and IV prolapse treated with VALSAC between April 2017 and June 2019. With a mean follow-up of 20 months, apical pelvic organ prolapse was cured in 95.7 % of patients. There was no complication in terms of mesh exposure, persistent pain, hematoma, infection. The mean pre- and post-operative POP-Q scores were, for the Aa point, 1.61 +/- 1.82 cm and -1.96 +/- 0.87 cm (p < 0.01), for the C point, 2.87 +/- 1.6 cm and -5.26 +/- 1.86 cm (p < 0.01) for the Ap point, -1.43 +/- 0.89 cm and -2.09 +/- 0.59 cm (p < 0.01). VALSAC is a promising minimally invasive technique for pelvic floor reconstruction that appears to provide good outcomes. Content: The main purpose of our study is to evaluate the efficacy and safety of vaginal assisted laparoscopic sacrocervicopexy with anterior colpotomy (VALSAC) for apical pelvic organ prolapse.Publication Open Access The protective effect of platelet-rich plasma administrated on ovarian function in female rats with Cy-induced ovarian damage(2020-04-01T00:00:00Z) ÖZCAN, Pınar; TAKMAZ, TAHA; Tok, Olgu Enis; Islek, Sevde; Yigit, Esra Nur; Ficicioglu, Cem; ÖZCAN, PINAR; TAKMAZ, TAHAPurpose We evaluated the protective effect of PRP on ovarian function in female rats with cyclophosphamide (Cy)-induced ovarian damage. Methods Thirty-two adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose ip injection), group 2 (Cy); 75 mg/kg, single-dose ip injection and sodium chloride 0.9% (1 mL/kg, single-dose ip injection), group 3 Cy plus PRP, Cy (75 mg/kg, single-dose and PRP (200 mu l, single-dose) ip injection), group 4 (PRP, 200 mu l, single-dose ip injection). Primordial, antral, and atretic follicle counts; serum anti-Mullerian hormone (AMH) levels; AMH-positive granulosa cells; and gene expression analysis of Ddx4 were assessed. Results Serum AMH levels were significantly lower in group 2 compared to groups 1, 3, and 4 (p < 0.01, p < 0.01, and p = 0.04, respectively). A significant difference was found in the primordial, primary, secondary, antral, and atretic follicle counts between all groups (p < 0.01). There was a statistically significant difference in AMH-positive staining primary, secondary, and antral follicles count between the groups (p < 0.01). There was a statistically significant difference in primary, secondary, and antral AMH positive staining follicle intensity score between the groups (p < 0.01). Ddx4 expression in group 4 was highest compared to other groups. Conclusion Our study may provide evidence that PRP could protect ovarian function against ovarian damage induced by Cy. It could lead to improved primordial, primary, secondary, and antral follicle numbers.Publication Open Access Vitamin D status in the first-trimester: effects of Vitamin D deficiency on pregnancy outcomes(2016-01-01) Ates, SEDA; Sevket, OSMAN; ÖZCAN, PINAR; ÖZKAL, Fulya; Kaya, MEHMET ONUR; Dane, Banu; ATEŞ, SEDA; ŞEVKET, OSMAN; ÖZCAN, PINAR; KAYA, MEHMET ONUR; KILIÇOĞLU DANE, PAKİZER BANUObjective: To assess serum levels of 25-hydroxyvitamin D [25(OH)D] in the first trimester and to determine the factors affecting deficiency levels and its association with pregnancy outcomes. Methods: Serum 25(OH)D concentrations were measured at 11-14 weeks' gestation in 229 singleton pregnancies using liquid chromatography-tandem mass spectrometry. Results: The median serum 25(OH)D concentration was 10.8 ng/mL and 45.9% of women had severe vitamin D deficiency with concentrations of <10 ng/mL. Logistic regression analysis revealed that covered dressing style, lack of multivitamin intake, season of blood sampling (November-April) were factors associated with 25(OH)D deficiency. There was a negative correlation between 25(OH)D levels and gestational age at sampling. Low 25(OH)D levels were not associated with adverse pregnancy outcomes. Higher rate of cesarean section (CS) was noted in women with 25(OH)D ≥10 ng/mL compared to those with 25(OH)D < 10mg/ml (p= 0.01). Conclusion: A high prevalence of vitamin D deficiency was observed in early pregnancy which was related to dress code, use of multi-vitamins and season at sampling. Low 25(OH)D levels were not related with adverse pregnancy outcomes. Women with severe vitamin D deficiency were more likely to deliver vaginally.Publication Open Access Retrospective analysis of patients with placenta previa Plasenta previa olgularının retrospektif incelemesi(2015-12-01) BATMAZ, Gonca; MOLLA, Fulya; MOLLA, Taner; ÖZCAN, PINAR; Dansuk, RAMAZAN; Dane, Banu; ÖZCAN, PINAR; DANSUK, RAMAZAN; KILIÇOĞLU DANE, PAKİZER BANUAim: To evaluate risk factors of patients with placenta previa and investigate management strategies. Methods: A retrospective review of medical records of 41 cases with placenta previa who were followed up in our center. The cases were evaluated according to demographic features, presence of placental invasion of the uterus, and necessity of blood transfusion. Requirement for a peripartum hysterectomy, relaparotomy rates and neonatal outcomes were also addressed. All patients with placenta previa were considered for elective surgery. Results: Eighteen patients, who did not have any sign of uterine invasion in their antenatal sonographic evaluations, were observed alike during cesarean section. In 23 patients, uterine invasion was detected by antenatal sonographic evaluations, 15 patients underwent hysterectomy due to invasion. Subsequent laparotomy was needed in four patients in whom hysterectomy was performed. Out of 15 patients, who underwent hysterectomy, 9 had placenta accreata, 2 had placenta percreata, and 2 had placenta increata. Organ-preserving treatment was performed in 8 patients who had a suspicious uterine invasion owing to their antenatal sonographic evaluations. Conclusion: In our study, abnormal placental invasion was predicted by antenatal sonographic findings. Multidisciplinary approach is required for patients with placenta previa to determine appropriate mode and timing of delivery.Publication Open Access Can Coenzyme Q10 supplementation protect the ovarian reserve against oxidative damage?(2016-09-01) OZCAN, PINAR; Ficicioglu, Cem; Kizilkale, Ozge; Yesiladali, Mert; Tok, OLGU ENİS; Ozkan, Ferda; Esrefoglu, MUKADDES; ÖZCAN, PINAR; TOK, OLGU ENİS; EŞREFOĞLU, MUKADDESPurpose: We investigated antioxidant effects of CoQ10 supplementation on the prevention of OS-induced ovarian damage and to evaluate the protective effect of such supplementation against OS-related DNA damage. Methods: Twenty-four adult female Sprague-Dawley rats were randomly divided into three groups (8 rats per group): group 1 (control): saline, ip, and orally; group 2 (cisplatin group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days; and group 3 (cisplatin + CoQ10 group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days, and 24 h before cisplatin, 150 mg/kg/day orally in 1 mL of saline daily for 14 days. Serum concentrations of anti-Mullerian hormone (AMH), number of AMH-positive follicles, the assessment of the intensity of 8'OHdG immunoreactivity, the primordial, antral and atretic follicle counts in the ovary were assessed. Result(s): The mean serum AMH concentrations were 1.3 ± 0.19, 0.16 ± 0.03, and 0.27 ± 0.20 ng/mL in groups 1, 2, and 3, respectively (p < 0.01). Serum AMH levels were significantly higher in group 1 compared to groups 2 and 3 (p < 0.01 and p = 0.01, respectively). There was a statistically significant difference in AMH-positive follicle count between the groups (p < 0.01). Group 1 showed higher numbers of AMH-positive granulosa cells compared to group 2 (p = 0.01). A significant difference was found in the primordial, the atretic, and antral follicle counts between the three groups (p < 0.01, p < 0.01, and p < 0.01, respectively). The atretic follicle count was significantly lower in the cisplatin plus CoQ10 group compared to the cisplatin group (p < 0.01). The antral follicle counts were significantly higher in the cisplatin plus CoQ10 group compared with the cisplatin group (p < 0.01). There was a statistically significant difference in the intensity of staining of the follicles that were positive for anti-8'OHdG between the groups (p = 0.02). Group 1 showed a significant lower intensity of staining of the follicles positive for anti-8'OHdG compared with group 2 (p = 0.03). Conclusion(s): CoQ10 supplementation may protect ovarian reserve by counteracting both mitochondrial ovarian ageing and physiological programmed ovarian ageing although the certain effect of OS in female infertility is not clearly known.Publication Open Access Analysis of preoperative and postoperative quality of life, sexual function, and sleep in patients with endometriosis: a prospective cohort study(2022-04-01T00:00:00Z) Halici, Belfin Nur Arici; Aktoz, Fatih; Kabakci, Meric; KIRAN, Gürkan; ÖZCAN, PINAR; KIRAN, GÜRKAN; ÖZCAN, PINARPurpose Endometriosis affects the quality of life, sleep, and sexual life of patients due to pain. This study compared the scores of endometriosis patients in these three areas before and after surgery. Methods Patients between the ages of 18 and 60 with a prediagnosis of endometriosis were enrolled. Postoperative histopathological diagnosis of endometriosis was confirmed in all patients. This study included 56 patients who completed pre- and postoperative (three months) evaluation of quality scale questionnaires: a visual analog scale for pelvic pain, the Pittsburgh Sleep Quality Index, Morningness-Eveningness Questionnaire, Endometriosis Health Profile-30 Questionnaire, and Female Sexual Function Index were administered prior to and 3 months after each patient-s surgery. Results Among the 56 female patients included in this study, statistically significant improvement was observed in pain scores, quality of life, sexual function, and sleep of all patients regardless of endometriosis stage. Conclusion Endometriosis is a disease that progresses, with increasing pain scores; it has negative effects on the quality of life, sexual function, and sleep of patients. Surgical or medical treatment can be performed considering the complaints and fertility status of the patients.
