    (Informa Healthcare, 2013) Kara, Fatih; Dogan, Nasuh Utku; Bati, Serap; Demir, Senay; Durduran, Yasemin; Celik, Cetin
    Objectives To evaluate patients' characteristics and complications of surgical abortion performed at an early gestation, compared to later gestations. Methods A total of 4310 women with unintended pregnancies attending the family planning unit of a government maternity hospital in Konya, Turkey, were included retrospectively. Abortions were carried out from 6 weeks' up to 10 weeks gestation. Results The gestational age in 62% of the cases was between 6 weeks and 6 weeks + 6 days. Only 8.5% of the 4310 women had used a modern contraceptive method, and 16% had had a surgical abortion for an unplanned pregnancy previously. These women were younger, had more siblings, and a shorter time had elapsed since their last pregnancy when compared to women who never had an abortion. There were four failures (0.09%). The rate of retained products of conception (RPCs) was 1.9% in women aborted between six and six(+6) weeks' gestation, and 6.2% (p < 0.001) in those aborted later. Women who had had a surgical abortion previously more often had RPCs than those who never had (16% vs. 1%, respectively, p < 0.001). Of the 151 women with RPCs, 65 (43%) had been using an intrauterine device prior to surgical abortion. Conclusion Early surgical abortion (at six-six(+6) weeks' gestation) generates few complications. Delaying surgical abortion until a somewhat later gestation causes complication rates (particularly RPCs) to increase.

    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 Utku
    Objectives: 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.

    P-wave parameters and cardiac repolarization indices: Does menopausal status matter?
    (Elsevier Ireland Ltd, 2012) Dogan, Umuttan; Dogan, Nasuh Utku; Basarir, Ahmet Ozgur; Yildirim, Serkan; Celik, Cetin; Incesu, Feyzanur; Ozdemir, Kurtulus
    Background and purpose: Data regarding electrocardiographic characteristics of postmenopausal women are lacking. In this prospective, cross-sectional study, electrocardiographic P-wave parameters and cardiac repolarization indices of age-matched pre- and postmenopausal healthy women were compared. We hypothesized that menopausal status would have a significant effect on cardiac electrical activity and hence electrocardiography (ECG) recordings. Materials and methods: Twelve-lead ECG recordings were obtained from 125 consecutively recruited postmenopausal healthy women aged between 44 and 54 years. The control group consisted of 125 age-matched premenopausal women. P-wave parameters and cardiac repolarization indices were measured and compared with respect to menopausal status. Results: Demographic features of premenopausal and postmenopausal women were comparable. There were no significant differences between two groups regarding mean values of heart rate, maximum and minimum P-wave duration, P-wave dispersion, maximum and minimum QT interval, and QT dispersion. Mean values of QT interval obtained from lead V5 were also similar. Corrected values which were calculated according to Bazett and Fridericia formulas also did not differ between the groups. Mean values of Tpeak to Tend (TpTe) (p < 0.001) and corrected TpTe (p = 0.001) intervals obtained from lead V5 were significantly shorter in postmenopausal women when compared to those without menopause. Conclusion: Tpeak to Tend interval decreased significantly while QT intervals and P-wave parameters did not change in postmenopausal women when compared to premenopausal women. Association of these findings with changes in levels of sex steroids and their prognostic implications need to be elucidated with further studies. (C) 2012 Japanese College of Cardiology.
