Öğe Comparison of the remineralisation effect of a glass ionomer cement versus a resin composite on dentin of primary teeth(Italian Society of Paediatric Dentistry, 2014) Aykut-Yetkiner A.; Şimşek D.; Eronat C.; Çiftçioglu M.Aim: The aim of this study was to investigate the interaction of a high viscosity glass ionomer cement (GIC) and a composite resin with caries affected dentin and to determine the remineralization levels. Materials and methods: In a split mouth design 24 GIC and composite resin atraumatic restorative treatment restorations were made in vivo and the teeth were collected after 2 years and subsequently sectioned and examined using Vickers microhardness test; the latter was performed starting from the dentin surface adjacent to the restoration. Repeated Measure ANOVA and Bonferroni statistical methods were used for data analysis. Results: The microhardness adjacent to the GIC restorative material resulted to be significantly higher. Conclusion: GIC resulted to be a better restorative material for the remineralization of caries affected dentin, though further studies are necessary for the corroboration of this finding. The GIC restored primary molar dentin had a higher level of remineralization and GIC could be the material of choice in pediatric dentistry.Öğe Comparison of three-dimensional ultrasound and magnetic resonance imaging diagnosis in surgically proven Müllerian duct anomaly cases(Elsevier Ireland Ltd, 2016) Ergenoglu A.M.; Sahin Ç.; Şimşek D.; Akdemir A.; Yeniel A.Ö.; Yerli H.; Sendag F.Objective To determine and compare the diagnostic accuracy of 3-dimensional ultrasound (3D US) and magnetic resonance imagining (MRI) in patients with surgically diagnosed Mullerian duct anomaly (MDA). Study design Charts of patients with MDA were retrospectively evaluated. Patients who underwent both laparoscopic and hysteroscopic surgery and had 3D US and MRI examinations were included in the study. The diagnoses achieved via 3D US and MRI were compared with the surgical diagnoses to determine the diagnostic accuracy of these imagining techniques. Results Twenty-nine patients were included in the study. Three-dimensional ultrasound detected 28 out of 29 (96%) patients correctly. Only one patient was diagnosed with a uterine septum instead of uterine arcuatus. Magnetic resonance imaging detected 23 out of 29 patients correctly (79%). The Kappa indexes of the 3D US and MRI were 0.896 and 0.592, respectively. Conclusion Our results indicate that 3D US has a higher diagnostic accuracy level than MRI in evaluating MDA, especially when used in experienced hands. However, additional, well-designed studies are needed to better compare the diagnostic accuracy of the 3D US and MRI. © 2015 Published by Elsevier Ireland Ltd.

F.; Öztekin M.K.Objective: To reduce the time period between emergency admission and operation, patients who were operated due to ovarian torsion, were evaluated in terms of clinical symptoms, diagnostic methods and treatment. We aimed to evaluate the management of the patient suspected ovarian torsion accompanied review of the literature. Material and Methods: Retrospective case review. Thirty-six patients who underwent laparoscopic ovarian torsion operation between 2010-2014 years were included in this study. Results: Surgically proved 36 cases of ovarian torsion were included in the study. The mean age of the patients was 27 years. Acute abdominal pain, vomiting and nausea were the main presenting symptoms. All the patients had abdominal tenderness and 13 of them (36%) had positive peritoneal signs in abdominal examination. None of the patients had fever. Adnexal mass was detected in almost all patients in vaginal ultrasound. Transabdominal ovarian color Doppler duplex ultrasound imaging results were obtained 28 patients which were performed by radiology physician. From these, 14(50%), 8(28%) and 6(22%) patients' ovarian duplex doppler imaging reported absent, decreased and normal blood flow respectively. Eight patients' doppler duplex ultrasound files were not able to find in the patients' file. All the patients underwent laparoscopic operation. Thirty of whom (83%) treated conservatively and 6 (16%) oophorectomy was performed. The median time interval from emergency service admission to operation was 9 hours and 20 minutes. This time period ranged 44 minutes and 25 hours 30 minutes. Conclusion: Ovarian torsion is hard to diagnose. The delay in diagnosis is the major obstacle for treatment. The biggest restriction is the lack of an appropriate imaging method or biochemical marker. To reduce the time between surgery and admission to the hospital, ovarian torsion diagnosis has to be preoccupied by any low abdominal pain synchronous with vomiting and detected abdominopelvic mass in bedside ultrasound. Laparoscopic conservative treatment should be considered as the first. To prevent the recurrence, cystectomy or adnexal fixation could be performed.

Materials and Methods: Women with two consecutive deliveries between 2016 and 2020 were included in the study. The maternal and neonatal outcomes of both pregnancies were reviewed. The time interval between consecutive deliveries was calculated. The patients were divided into two groups in terms of IDI either less or more than 24 months. Results: The number of patients with short IDI (?24 months), and normal IDI was 1.915 and 1.370, respectively. About 15% of the women in both groups had at least one obstetric morbidity. The rates of uterine rupture, placenta previa, and peripartum hysterectomy were higher in women with short IDI. The number of patients with low birth weight, very low birth weight, and stillbirth was higher in the short IDI group. Conclusion: Patients with short interpregnancy intervals should be considered high-risk pregnancy. Adequate contraceptive methods should be used to prevent unintended pregnancies. © 2022 by Turkish Society of Obstetrics and Gynecology.
