    (2016) Unler, Gulhan Kanat; Gokturk, Huseyin Savas; Toprak, Erzat; Erinanc, Ozgur Hilal; Korkmaz, Huseyin; https://orcid.org/0000-0003-0182-002X; https://orcid.org/0000-0002-2877-1232; https://orcid.org/0000-0003-1401-6356; 26897266; ABI-5902-2020; AAL-1268-2021
    Introduction: Endometrial polyps (EPs) and colorectal polyps (CPs) are common disorders and the incidence of both increase rapidly with aging. CPs are focal lesions and incidence increases with age. Aim: In this study, we aimed to analyze retrospectively the relationship between the EPs and CPs sharing similar clinical and genetic factors in their etiopathogenesis. Materials and Methods: This study was retrospectively performed between 2010 and 2013 and it included patients diagnosed to have eEPs. The study group and the control group consisted of patients who were diagnosed with or without EPs and who underwent colonoscopy at the same period. Results: The study group was formed by 57 patients with diagnosis of EP who underwent colonoscopy during the same period. The control group consisted of 71 patients without EP examined with colonoscopy. Among 128 patients assessed in this study, 24 were diagnosed with CPs, all of which were adenomatous polyps smaller than 1 cm. No hyperplastic or inflammatory polyps were diagnosed. While 18 of 57 patients with EPs had CPs, 6 of 71 control subjects had CPs. Hence, the risk of having CP was 5 times greater in patients with EP compared to those without (P < 0.05). Conclusion: The present study demonstrated that the prevalence of CPs increased significantly in postmenopausal patients with EPs. Recommending colonoscopy to these patients irrespective of age may be beneficial for detecting more CPs and preventing colorectal cancer.

    (2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Karakoca, Aydin; Erinanc, Ozgur Hilal; 0000-0001-6503-3872; 0000-0003-1401-6356; 0000-0003-0182-002X; 26621567; AAF-8985-2020; AAL-1268-2021; AAG-3273-2020
    BackgroundThe H. pylori eradication success is low in countries with high antibiotic resistance to H. pylori. ObjectiveWe retrospectively assessed the eradication rates achieved by five different regimens and aimed to compare the efficiency of bismuth enhanced sequential therapy and other treatments in a gastroenterology outpatient clinic a university-affiliated hospital. DesignOur study was carried out with a retrospective cohort design. SettingThis study assessed the gastroscopy examinations of patients. PatientsA total of 621 patients were included in the study. There were 122 patients in the quadruple treatment group, 168 patients in the classical sequential treatment group, 130 patients in the bismuth enhanced sequential therapy, 113 patients in the sequential treatment with levofloxacin, and 88 patients in the hybrid treatment. MeasurementsEradication rates of different regimens was analyzed by performing Chi-square and Tukey's honest significant difference test. ResultsEradication rates by ITT and PP analysis achieved by treatment groups were 74.6 and 75.6% in the quadruple treatment; 70.2 and 70.4% in the sequential treatment with clarithromycin, 88.5 and 90.3% in the bismuth enhanced sequential therapy, 77.9 and 78.5% in the sequential treatment with levofloxacin, and 76.1 and 76.2% in the hybrid treatment. LimitationsThe main limitation of our study was its retrospective nature. Different proton pump inhibitors were used in the treatment arms. ConclusionsBismuth-enhanced sequential therapy can be recommended to overcome resistance.

    Serum and placental periostin levels in women with early pregnancy loss
    (2020) Eroglu, Semra; Colak, Eser; Erinanc, Ozgur Hilal; Ozdemir, Duygu; Ceran, Mehmet Ufuk; Tasdemir, Umit; Kulaksizoglu, Sevsen; Ozcimen, Emel Ebru; 0000-0003-1401-6356; 0000-0002-7613-2240; 0000-0002-9959-9433; 32460058; AAL-1268-2021; AAI-8932-2021
    Objectives: Periostin is secreted from the placenta in the embryonic period and it is emphasized that it may be involved in endometrial implantation. In this study, we aimed to investigate periostin serum levels and placental tissue expression in first trimester pregnancy losses. Study design: In this prospective case-control study, 30 patients who underwent dilatation and curettage with first trimester spontaneous abortion (< 10 weeks of gestation) were included in the study group and 30 patients who had voluntary pregnancy termination (< 10 gestational weeks) were included in the control group. Serum samples collected from the study and control groups were analyzed usingenzyme-linkedimmunosorbent assay (ELISA), and trophoblastic and decidual tissues were examined using immunohistochemical staining with streptavidin-biotin-peroxidase techniques. Results: There were no significant differences between the groups in terms of age, gravida status, parity number, gestational week, and number of previous abortions. In the spontaneous abortion group, the serum level of periostin was significantly lower than in the voluntary termination group (6.56 +/- 4.16 pg/mLvs. 9.51 +/- 4.52 pg/mL, p = 0.03). There was no significant difference between the two groups in terms of periostin expression in decidual and trophoblastic tissue (p = 0.617, p = 0.274, p = 0.497). Conclusion: Periostin serum levels were significantly reduced in patients with spontaneous pregnancy loss. Periostin can be used as a predictive marker for the success of endometrial implantation.

    Is there any association between colonic polyps and gastric intestinal metaplasia?
    (2016) Unler, Gulhan Kanat; Ozgur, Gulsum Teke; Gokturk, Huseyin Savas; Korkmaz, Huseyin; Erinanc, Ozgur Hilal; 27210777
    Background/Aims: Chronic gastritis progression is a multistep process of atrophy, intestinal metaplasia (IM), and dysplasia, which may lead to invasive carcinoma. In this study, we identified an association of colonic polyps with gastric IM in patients undergoing colonoscopy. Materials and Methods: This retrospective case-control, cross-sectional study was conducted in a tertiary-care institution in Turkey. Pathology and endoscopy reports were reviewed. The study group comprised 400 patients with colonic adenomatous polyps, and the control group comprised 360 patients without colonic adenomatous polyps on colonoscopy. Results: The risk of gastric IM was 1.42-fold higher in the study group (p<0.05). The risk of IM in patients aged >= 50 years with colonic polyps was 3.35-fold higher than in those aged <50 years (p<0.05). The risk of Helicobacter pylori infection in the study group was 1.07-folder higher than that in the control group (p<0.05). H. pylori infection prevalence was higher only in patients with high-grade colonic polyp dysplasia (p<0.05). There were no statistically significant differences in the proportion of incomplete IM between the groups (p<0.05). Conclusion: This study observed increased rates of gastric IM with colonic polyps. An increased risk of gastric IM was associated with higher grades of polyp dysplasia.
