Öğe Comparison of "sandwich chemo-radiotherapy" and six cycles of chemotherapy followed by adjuvant radiotherapy in patients with stage IIIC endometrial cancer: a single center experience(SPRINGER HEIDELBERG, 2013) Dogan, Nasuh Utku; Yavas, Guler; Yavas, Cagdas; Ata, Ozlem; Yilmaz, Setenay Arzu; Celik, CetinTo compare "sandwich chemo-radiotherapy" with six cycles of chemotherapy followed by adjuvant radiotherapy with respect to tolerability and acute toxicity. Twenty-five women with surgically staged IIIC endometrial cancer were included. Treatment consisted of either three cycles of paclitaxel (175 mg/mA(2)) and carboplatin (AUC 6) on a q21-day schedule followed by irradiation (45-50.4 Gy) or six cycles of the same chemotherapy followed by radiotherapy. Acute toxicity related to either chemotherapy or radiotherapy was evaluated. Median age was 61.5 years (range 36-83 years). Eleven patients had sandwich chemo-radiotherapy, and the other 14 patients had 6 cycles of chemotherapy followed by radiotherapy. Three out of the five patients who could not complete all the cycles in the sandwich chemo-radiotherapy group had pelvic and para-aortic radiotherapy. Acute radiotherapy related grade 1-2 gastrointestinal system (GIS) and genitourinary system (GUS) toxicities were observed in 72.8 and 63.6 % of patients, respectively, for sandwich group. Undesired treatment breaks in the course of radiotherapy were observed in six patients for sandwich chemo-radiotherapy and in one patient receiving six cycles of chemotherapy followed by radiotherapy. All the patients who had undesired treatment breaks in the sandwich chemo-radiotherapy group had pelvic and para-aortic radiotherapy. Sandwich chemo-radiotherapy seems to be more toxic particularly for patients who had pelvic and para-aortic irradiation. Therefore, it might be more convenient to delay radiotherapy after six cycles of chemotherapy for patients with the indication of pelvic para-aortic radiotherapy.Öğe Depressive symptomatology and quality of life assessment among women using the levonorgestrel-releasing intrauterine system: an observational study(SPRINGER HEIDELBERG, 2014) Pekin, Aybike Tazegul; Kerimoglu, Ozlem Secilmis; Kebapcilar, Ayse Gul; Yilmaz, Setenay Arzu; Benzer, Nilgun; Celik, CetinThe aim of our study was to examine the effect of the levonorgestrel-releasing intrauterine system (LNG-IUS) treatment on depressive symptoms, changes in bleeding patterns, and quality of life (QoL) among premenopausal women in our clinic. We recruited 120 premenopausal women, aged 18-50 years, who had sought care in the previous year for menorrhagia. LNG-IUS was inserted into eligible patients after the relevant evaluations. Both questionnaires were administered at time of the initial screening before and 6 months after insertion of the LNG-IUS. All patients completed the 36-item Short-Form Health Survey (SF-36) for QoL and Beck's Depression Inventory for depressive symptoms. At the 6-month follow-up visit, the pictorial blood assessment chart score (PBAC) considerably decreased (p < 0.001). For SF-36 scores, physical functioning, physical role limitations, emotional role limitations, bodily pain, vitality, and mental health scores improved significantly after treatment (p < 0.001). Depression scores showed no significant difference from baseline to 6 months (p = 0.375). The LNG-IUS for the treatment of menorrhagia increases the QoL, and depression scores did not increase significantly in 6 months.Öğe Does lymphadenectomy have influence on postoperative body fluid distribution?(ELSEVIER SCIENCE BV, 2017) Ilhan, Tolgay Tuyan; Ucar, Mustafa Gazi; Pekin, Aybike Tazegul; Yilmaz, Setenay Arzu; Kerimoglu, Ozlem Secilmis; Celik, CetinObjective: We compared the fluid volume parameters in women undergoing gynaecological surgery for benign and malignant conditions before and after surgery using bioelectrical impedance vectors. Study design: A total of 181 patients were enrolled. In all, 89 patients had surgery for benign conditions and 92 patients underwent oncological procedures, including lymph node dissection, for malignant diseases. Bioelectrical impedance analysis (BIA) parameters were measured on the day of hospitalisation before any treatment and at 24h and 1 month after the surgical intervention. The BIA parameters measured included extracellular water (ECW), intracellular water (ICW), and total body water (TBW). Results: TBW increased significantly 1 month after surgery in all cases (p < 0,05 in both group). ECW was significantly higher (p < 0.05) and ICW was significantly lower (p < 0,05) in the malignant group than the benign group. Conclusion: Radical gynaecological surgeries, including lymph node dissection, have a greater effect on body water distribution than surgeries performed for benign conditions. (C) 2017 Elsevier B.V.

MethodsBetween 2011 and 2013, bioelectrical impedance analysis and body size measurements of 94 patients whose endometrial biopsy revealed endometrial cancer were obtained. Patients were divided into two groups according to body mass index (BMI) (normal, <30kg/m(2); elevated, 30kg/m(2)), and also classified by %BF (normal, <32%; elevated, 32%). ResultsThe patients' mean age was 55.010.9 years. Mean %BF and BMI were 40.8%+/- 9.8% and 32.9 +/- 7.5, respectively. Eighty-three (88%) patients were obese according to %BF; 54 (57%) were obese according to BMI. Patients with elevated %BF were more likely to have less than 50% myometrial invasion (P=0.004). Significantly more para-aortic lymph nodes were retrieved in patients with normal %BF or BMI (P<0.001, P<0.001). Patients with elevated %BF had longer operating times (P=0.043) and were more likely to have stage I disease than patients with normal %BF (P<0.001). ConclusionEndometrial cancer patients with an elevated %BF are more likely to have stage I disease and less than 50% myometrial invasion than patients with normal %BF. Defining obesity by BF may provide better estimation of obesity prevalence in patients with endometrial cancer and further understanding the relationship between BF with endometrial cancer may give more information about the effects of obesity on endometrial cancer.Öğe Effects of propofol and sevoflurane on isolated human umbilical arteries pre-contracted with dopamine, adrenaline and noradrenaline(WILEY-BLACKWELL, 2015) Gunduz, Ergun; Arun, Oguzhan; Bagci, Sengal Taylan; Oc, Bahar; Salman, Alper; Yilmaz, Setenay Arzu; Celik, CetinAimTo assess the effects of propofol and sevoflurane on the contraction elicited by dopamine, adrenaline and noradrenaline on isolated human umbilical arteries. MethodsUmbilical arteries were cut into endothelium-denuded spiral strips and suspended in organ baths containing Krebs-Henseleit solution bubbled with O-2+CO2 mixture. Control contraction to phenylephrine (10(-5)M) was recorded. Response curves were obtained to 10(-5)M dopamine, 10(-5)M adrenaline or 10(-5)M noradrenaline. Afterwards, either cumulative propofol (10(-6)M, 10(-5)M and 10(-4)M) or cumulative sevoflurane (1.2%, 2.4% and 3.6%) was added to the organ bath, and the responses were recorded. Responses are expressed percentage of phenylephrine-induced contraction (meanstandard deviation) (P<0.05=significance). ResultsPropofol and sevoflurane elicited concentration-dependent relaxations in strips pre-contracted with dopamine, adrenaline and noradrenaline (P<0.05). Highest (10(-4)M) concentration of propofol caused significantly higher relaxation compared with the highest (3.6%) concentration of sevoflurane in the contraction elicited by dopamine. High (10(-5)M) and highest concentrations of propofol caused significantly higher relaxation compared with the high (2.4%) and highest concentrations of sevoflurane on the contraction elicited by adrenaline. High and highest concentrations of sevoflurane caused significantly higher relaxation compared with the high and highest concentrations of propofol on the contraction elicited by noradrenaline. ConclusionDopamine, adrenaline and noradrenaline elicit contractions in human umbilical arteries, and noradrenaline causes the highest contraction. Both propofol and sevoflurane inhibit these contractions in a dose-dependent manner. Propofol caused greater relaxation in the contractions elicited by dopamine and adrenaline while sevoflurane caused greater relaxation in the contraction elicited by noradrenaline.Öğe Evaluation of Toll-Like Receptor Expression with Clinicopathologic Variables in Endometrium Cancer(YERKURE TANITIM YAYINCILIK HIZMETLERI AS, 2018) Bakbak, Berat Berrin Gencoglu; Ilhan, Tolgay Tuyan; Pekin, Aybike; Kerimoglu, Ozlem Secilmis; Yilmaz, Setenay Arzu; Kebapcilar, Aysegul; Dogan, Nasuh UtkuObjectives: Clinical evidence supports the association of toll-like receptor (TLR) with abnormal cell proliferation and cancer. In this study, we investigated the expression of TLRs 2, 4, 5, and 6 in healthy endometrium and endometrium cancer to study the relationship of these receptors' expression with carcinogenesis. Methods: Patients who had undergone a hysterectomy owing to endometrium cancer (group 1, 66 patients), endometrial hyperplasia (group 2, 14 patients), and other reasons besides endometrium cancer (group 3, 20 patients as controls) were included. The cases in the first group were classified by histological type of the cancer, stage, grade, and size of the tumor. In all the cases, expressions of TLRs 2, 4, 5, and 6 were assessed, and the relationship of these receptors with clinicopathologic signs was analyzed. For immunohistochemical staining, nuclear and cytoplasmic stainings were considered positive. A Chi-squared test was used to assess the correlation of the groups. A p<0.05 was considered significant. Results: The mean ages of patients in groups 1, 2, and 3 were 59.8 (range 33-83), 48.3 (range 40-59), and 53.4 (range 38-84) years, respectively. All types of TLRs were highly expressed in both types of endometrium cancer (groups 1 and 2). TLR expression was observed with a ratio of 87.9% in group 1, 100% in group 2, and 35% in group 3. There was a statistically significant association of TLR 2 among the three groups (p=0.000). TLR 6 expression in both group 1 and group 2 was significantly higher than that in the control group (p=0.000, p=0.000, respectively). In addition, TLR 6 was higher in cases with late-stage cancer (p=0.033). Regarding tumor grade and the size of the tumor, no association was found between TLR 2 and TLR 6. Conclusion: TLR 2 and TLR 6 were significantly more expressed in cases with endometrium cancer and endometrial hyperplasia. In addition, the presence of TLR 6 may indicate the presence of late-stage endometrial cancer.Öğe Follicle-stimulating hormone receptor gene polymorphisms in women with endometriosis(SPRINGER HEIDELBERG, 2015) Kerimoglu, Ozlem Secilmis; Yilmaz, Setenay Arzu; Pekin, Aybike; Nergiz, Suleyman; Incesu, Feyzanur; Dogan, Nasuh Utku; Acar, HasanThe purpose of this study was to evaluate the influence of the follicle-stimulating hormone (FSH) receptor poymorphisms Asn680Ser and Thr307Ala on endometriosis in Turkish women. Polymorphic analysis of the FSH receptor gene was performed in 100 patients with endometriosis and 100 controls. Genomic DNA was obtained from peripheral blood leukocytes and polymorphisms were investigated using restriction fragment length polymorphism analysis. There were no significant differences in genotype frequencies of FSH receptor gene between endometriosis patients and controls. When the patients were divided into two groups according to disease severity, we found that the patients with the SS (680 Ser/Ser) or AA (307 Ala/Ala) genotype were less likely to develop stage 3-4 endometriosis compared to the stage 1-2 endometriosis group (P = 0.004; OR: 0.177, 95 % CI 0.055-0.568 and P = 0.040; OR: 0.240, 95 % CI 0.061-0.938; respectively). The distributions of FSHR polymorphisms may not have an effect on endometriosis development but they are associated with the severity of the disease. The polymorphisms encoding SS at the position 680 and AA at the position 307 and the patients with the genotype that included alanine or serine were less likely to develop stage 3-4 endometriosis compared to the stage 1-2 endometriosis group.Öğe Predictive value of second and third trimester fetal renal artery Doppler indices in idiopathic oligohydramnios and polyhydramnios in low-risk pregnancies: A longitudinal study(WILEY, 2015) Benzer, Nilgun; Pekin, Aybike Tazegul; Yilmaz, Setenay Arzu; Kerimoglu, Ozlem Secilmis; Dogan, Nasuh Utku; Celik, CetinAimIntermittent assessment of renal artery flow velocity waveforms during the early stages of pregnancy may help in predicting changes in amniotic fluid dynamics. The current study sought to determine the relation of renal artery and umbilical artery flow velocity waveforms with normal pregnancies and pregnancies complicated by either polyhydramnios or oligohydramnios. Material and MethodsRenal and umbilical artery Doppler values were evaluated at 22, 28 and 34 weeks' gestation in 300 low-risk pregnant women with singleton pregnancies. Pulsatility index (PI) and resistance index (RI) were recorded and the amniotic fluid volume was evaluated. Three groups were formed according to the amniotic fluid volume at birth. Group I consisted of 264 pregnant women with normal amniotic fluid, group II included 30 pregnant women with oligohydramnios and group III included six pregnant women with polyhydramnios. Doppler parameters were compared between the groups and within each group according to gestational age. ResultsRenal artery PI values were higher in group II than group I at 22 weeks, 28 weeks and 34 weeks. The PI value at 28 weeks' gestation was statistically significant (P=0.011). At 28 weeks' gestation, group II also had higher umbilical artery PI and RI values than group I. ConclusionAn increase in renal artery PI develops in early pregnancy before the development of oligohydramnios. In pregnancies developing polyhydramnios, renal artery PI was lower; however, our study included a small number of women with polyhydramnios.Öğe Screening and genotyping of group B streptococcus in pregnant and nonpregnant women in Turkey(J INFECTION DEVELOPING COUNTRIES, 2016) Alp, Feyza; Findik, Duygu; Dagi, Hatice Turk; Arslan, Ugur; Pekin, Aybike Tazegul; Yilmaz, Setenay ArzuIntroduction: The purpose of this study was to investigate group B streptococcus (GBS) colonization, to compare the methods, to determine the relationship between GBS carriage and risk factors, and to genotype the GBS isolates. Methodology: Recto-vaginal swab specimens were obtained from 500 women, and a questionnaire was administered to each to assess their risk factors for GBS carriage. A culture, GBS antigen test, and polymerase chain reaction (PCR) were performed on all samples. Antibiotic susceptibility testing was performed, and the clonal relationship was determined by pulsed-field gel electrophoresis (PFGE) on all viable isolates. Results: Of the 500 women, sixty-eight (13.6%) women were GBS carriers, of whom 9.8% were pregnant and 16.5% not. There was a significant difference between GBS carriage and history of premature rupture of membrane (PROM). GBS was isolated from 65 (13%) samples. GBS was positive in 70 (14%) samples by antigen test and in 62 (12.4%) by PCR. Sixty-eight of the 70 positive antigen tests were confirmed by PCR or culture. Fifty-five isolates were resistant to tetracycline, 16 to erythromycin and clindamycin, and 13 to levofloxacin. Thirteen different pulsotypes and 17 sporadic strains were determined by PFGE. Conclusions: GBS carriage rate in non-pregnant women was higher than in pregnant women. The GBS antigen test was more sensitive than culture and PCR. GBS isolates did not originate from a single clone and contained sporadic strains. There was a significant difference between GBS carriage and history of PROM. Epidemiologic data obtained in this study will help future studies.
