Öğe An Unusual Cervical Mass in the Hyoid Bone: Intermediate-Grade Chondrosarcoma(Hindawi Ltd, 2019) Caglar, Ozge; Karatag, O.; Avci, A.; Derekoy, SefaWe describe a case of a 31-year-old woman with a chondrosarcoma of the hyoid bone. The patient presented with a mass in the left submandibular region. Fine-needle aspiration cytology suggested chondroma, but further imaging investigation with CT revealed an exophytic tumor originating from the body of the hyoid bone. Histopathology of the surgical specimen confirmed the diagnosis of a intermediate-grade chondrosarcoma. Chondrosarcomas account for 11% of all bone cancers. Primary sites of the head and the neck include the nasal cavity, the skull base, the maxilla, the mandible. Chondrosarcomas of the hyoid bone are very rare, with only 23 cases previously reported in the literature.Öğe Comparison of Different Treatment Methods for Idiopathic Sudden Sensorineural Hearing Loss(Galenos Publ House, 2018) Toroslu, Tolgahan; Erdogan, Halil; Caglar, Ozge; Guclu, Oguz; Derekoy, Fevzi SefaObjective: To evaluate the effectiveness of different therapies for idiopathic sudden sensorineural hearing loss and prognostic factors, and determine the most successful treatment according to the audiogram type and time from onset to treatment. Methods: A total of 90 cases from February 2009 to January 2015 were classified under Group I oral treatment (methylprednisolone, acyclovir, betahistine-dihydrochloride, and vitamin B12); Group II oral treatment + intratympanic steroids (ITS); Group III oral treatment + hyperbaric oxygen; and Group IV only ITS. A pure tone average (PTA) improvement of less than 10 dB was assessed as noimprovement, a PTA of 10 dB or more or a 10% or more increase in the speech discrimination score (SDS) as partial improvement, and a hearing threshold within 10 dB and SDS within 5%-10% of the unaffected ear as full improvement. Results: Overall, 32.2% patients showed full and 28.9% showed partial improvement, whereas 38.9% showed no improvement. There was no significant difference in terms of mean hearing gain between the different treatment methods. As the degree of hearing loss and time from onset to treatment increased, improvement worsened (p<0.05). Descending audiogram had lower mean hearing gains compared to other groups (p=0.014). There was no significant effect of age, sex, tinnitus and/or vertigo, and systemic disease on treatment success (p>0.05). Conclusion: The most important factors affecting prognosis were the time from onset to treatment, hearing loss severity, and audiogram type. Only ITS avoided side effects and reduced hospitalization. ITS in the first two weeks, followed by hyperbaric oxygen were considered as the treatment priority.Öğe Evaluation of circulating cell free DNA in plasma as a biomarker of different thyroid diseases(Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2020) Caglar, Ozge; Cilgin, Begum; Eroglu, Mustafa; Cayir, AkinIntroduction: Many studies have been done on proteomics, genomics, epigenetic, immuno-genetics in many body fluids. Among these, circulating cell-free DNA (ccfDNA) entered the literature in 1948, but it has not been studied for many years due to technological deficiencies. Following recent advances, geno-metastasis has been mentioned and new research is needed in this area. ccfDNA is known to be an important biomolecule in this regard. Objective: The presence of cell-free DNA in the circulatory system may offer a tremendous opportunity to provide novel biomarkers for thyroid diseases. This experimental study was conducted to determine the amount of ccfDNA in different thyroid diseases, then to evaluate whether the ccfDNA concentration varied between the disease groups and control group. Methods: In total, we included 121 individuals in the present study. We collected blood samples and then determined the ccfDNA concentration in plasma of collected blood samples from three groups: thyroiditis (n=33), benign (n =37), and malignant (n =30) and from a control group (n=21). Results: The median values of the ccfDNA groups were found as 1610, 1665, 1685 and 576 ng/mL for the thyroiditis, benign, malign, and control groups, respectively. Findings showed that the ccfDNA of the three groups was significantly higher than the control (p <0.0001). Each group was compared in terms of ccfDNA and the p-values of benign-thyroiditis, benign-malign, and thyroiditis-malign were 0.09, 0.65, and 0.29, respectively. Conclusions: The clear differences between thyroid diseases and controls suggest that ccfDNA is worthy of attention as a biomarker for further evaluation of different thyroid diseases. Likewise, it might indicate a clear tendency that ccfDNA can also be used to distinguish different thyroid diseases. (C) 2019 Associacao Brasileira de Otorrinolaringologia e Cirurgia Cervico-Facial.

The cytokinesis-blocked micronucleus assay (CBMN) was applied to the blood samples to measure the frequency of the markers in both groups. The frequencies of MN of hearing loss patients were found to be consistently significantly higher than those obtained for the control group (p < 0.0001). Similarly, we found significantly higher frequency of NPB in patients was obtained for the patient group (p < 0.0001). Finally, the frequencies of NBUD in patients is significantly higher than the level measured in the control group (p < 0.0001). Furthermore, the age-adjusted MNL, BNMN, NPB, and NBUD frequencies in the patients were significantly higher than those obtained in the control group. We observed that the frequency of MN in patients was positively correlated with NBUD frequency which may indicate a common mechanism for these biomarkers in the patient group. We found, for the first time, that there were statistically significant higher levels of MN, NPB, and NBUD in sensorineural hearing loss patients. Since the markers we evaluated were linked with crucial diseases, our findings might suggest that sensorineural hearing loss patients are susceptible to several crucial diseases, especially cancer. Furthermore, the results demonstrated the significance of the MN, NPB, and NBUD level and thus provides a potential marker for the diagnosis of congenital hearing loss patients.Öğe Evaluation of Heart Functions With Detailed Echocardiogram in Patients With Septum Deviation(Lippincott Williams & Wilkins, 2018) Caglar, Ozge; Aksit, ErcanBackground: One of the most important reasons for nasal congestion is septum deviation. Nasal septal deviation increases airway resistance and can cause systemic problems. In this study, echocardiographic findings were compared with the normal population to see how cardiac function was affected in patients with obstructive nasal septum deviation. Methods: This study included a young patient group with 44 obstructive septum deviation patients and 30 healthy individuals with no nasal-related problems. Echocardiography was performed by the same cardiologist and results were compared with normal patients. The authors got permission from the ethics committee of faculty for the study (E. 116795). Results: In the patient group with septum deviation, pulmonary artery pressure was high. In addition, the size of the right heart chambers was also increased. TAPSE, pulmonary acceleration time, ejection fraction, and right ventricular outflow tractfractional shortening were found to be lower than the normal group. Conclusion: Patients with obstructive septum deviations should be evaluated early for cardiologic functions.Öğe Micronucleus, nucleoplasmic bridge and nuclear bud frequencies in patients with laryngeal carcinoma(Pacini Editore, 2020) Yazici, Ibrahim; Caglar, Ozge; Guclu, Oguz; Cobanoglu, Hayal; Coskun, Mahmut; Coskun, Munevver; Kilic, AytacThe aim of the study is to determine and compare micronucleus (MN), nucleoplasmic bridge (NPB) and nuclear bud (NBUD) frequencies in patients with laryngeal carcinoma and healthy controls. The study was conducted in the School of Medicine of Onsekiz Mart University. A total of 102 volunteers, 51 of whom had laryngeal carcinoma and 51 of whom were healthy control subjects, participated in this study. The Cytokinesis-Block Micronucleus Assay (CBMN) was applied to peripheral blood lymphocytes taken from patients and controls. We evaluated MN, NPBs and NBUDs frequencies in patients with laryngeal carcinoma and compared the results with those in the control group. The frequencies of MN, NPBs and NBUDs of patients with laryngeal carcinoma were found significantly higher than those in the control group (P = 0.01, P = 0.004, P = 0.01, respectively). MN, NPB and NBUD frequencies were also compared in the patients with and without pesticide exposure, and the means of all frequencies was higher in patients with pesticide exposure (P = 0.001, P = 0.02 respectively). The MN, NPBs and NBUDs frequencies of the patients with laryngeal cancer were significantly higher than those of the control group, and pesticide exposure might be a risk factor that increases genomic instability and risk of laryngeal cancer.Öğe Monostotic fibrous dysplasia invading the inferior turbinate: Computed tomography and magnetic resonance imaging findings(Colegio Brasileiro de Radiologia, 2019) Resorlu, Mustafa; Karatag, Ozan; Uysal, Fatma; Caglar, Ozge[No abstract available]Öğe The Effects of Different Types of Nasal Packing on Odor Function and Mucociliary Function After Septum Surgery(Sage Publications Inc, 2019) Caglar, Ozge; Guclu, Oguz; Oymak, Sibel; Derekoy, SefaBackground: In this study, we evaluated how the Merocel and nasal splint packing placed in the nose after septoplasty surgery affects the olfactory and mucociliary functions of the nose in the early period, and compared the 2 packing with each other. Material and Method: The study included 60 patients with isolated septal deviation and 30 patients in the control group. The patients were randomly divided into 2 groups. Nasal splint was inserted after septoplasty in group A (n = 30). Merocel was inserted in group B (n = 30). The Sniffin sticks test and saccharin test were applied to the patients before surgery and 15 days after the surgery. The same tests were applied to the control group consisting of 30 patients and the results were compared. Results: No complications, such as postoperative bleeding, submucoperichondrial hematoma, or abscess formation, were found in both groups. Mucociliary function was improved after septoplasty, and it was statistically significant, but there was no statistically significant difference between both packing groups. A statistically significant difference was found for the odor test in patients who used nasal splint packing in comparison with patients who used Merocel in the early period. Conclusion: The odor test showed significant differences between the 2 groups and this was statistically significant in the early period. Mucociliary function was better after surgery, but there was no statistical difference in the different nasal packing groups.Öğe The role of anxious temperament in patients with allergic rhinitis(Saudi Med J, 2019) Tas, Halil Ibrahim; Caglar, OzgeObjectives: To evaluate the depressive and anxiety levels in allergic rhinitis (AR) and to investigate the relationship between depression and anxiety symptoms and depressive and anxious temperament features. Methods: The study design is cross-sectional. The study was conducted between January 2017 and January 2018. Patients (n= 101) diagnosed with AR and healthy controls (n= 74) were included in this study. All participants were assessed with the Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris, San Diego Autoquestionaire). Results: The median BAI and BDI scores of the patients were found to be significantly higher than the control group (p=0.016 and p=0.001). In AR patients, the percentage of depressive and anxious temperaments were significantly higher than in the control group (p=0.029). Depressive temperament scores showed strong positive correlation with anxious temperament and BDI scores and a medium relationship with the BAI (r; p=0.639; p< 0.001, p= 0.671; p< 0.001, and p= 0.495; p< 0.001, respectively). Participants with anxious temperament had 6.3-times (95% CI: 1.3-28.3) the risk for developing AR. Conclusion: Screening of temperament traits in AR patients may allow prediction of future depression and anxiety symptoms. These temperament traits may be mediators of depression and anxiety in AR patients. Depressive and anxious temperament traits may contribute to both depression and allergy.Öğe Total circulating cell-free miRNA in plasma as a predictive biomarker of the thyroid diseases(Wiley, 2019) Caglar, Ozge; Cayir, AkinBackgroundThyroid cancer is a common endocrine cancer. Great progress has been made in resolving its molecular mechanisms in recent years. The molecular changes observed in thyroid cancer can be used as biomarkers for diagnostic, prognostic and therapeutic purposes. MicroRNAs (miRNAs) are important components in biological and metabolic pathways, such as developmental stages, signal transduction, cell maintenance, and differentiation. Hence, their malfunctioning can expose humans to malignancies. miRNA expressions have been shown to be dysregulated in different tumor types, like thyroid cancer, and may cause tumor initiation and progression. In previous studies, only cancer has been studied, and miRNA has been detected from the tissues in all the studies performed. In this study, we have focused on thyroid diseases such as bening nodules and Hashimoto's disease, which might be the cause of thyroid cancer, and have carried out miRNA tests in the blood samples taken from the arms thyroid patients. Material and methodThe present study was conducted on the blood samples of 100 thyroid patients. Of the 100 patients in our study, 33 consisted of patients with thyroiditis, while 37 patients were diagnosed with benign thyroid nodules and 30 patients had thyroid cancer. For the control group, 18 patients were included. The plasma samples were analyzed, and the total miRNA levels were determined. ResultsWe found that the ccf-miRNA amount of benign patients is significantly lower than that of the controls. Similarly, the miRNA amount in the controls is significantly higher than that of the thyroiditis (P=0.06) and the malign groups miRNA (P=0.084). Although the present study has a low number of patients, the plasma samples could be used as a source of circulating miRNAs. In addition, the total miRNA of thyroid diseases could be used as a biomarker for different types of thyroid diseases. We could suggest, for future study, that specific miRNAs in bodily fluid might show specific properties to be used as biomarkers of thyroid diseases.
