Öğe COMPARISON OF EFFECTS OF INTRAVITREAL VERSUS POSTERIOR SUBTENON TRIAMCINOLONE ACETONIDE INJECTION ON INTRAOCULAR PRESSURE IN PATIENTS WITH DIABETIC MACULAR EDEMA(Wichtig Publ, 2015) Atay, A. E.; Balyen, L.; Balyen, L. S. D.; Pasa, S.; Satici, O.[Abstract Not Available]Öğe Evaluation of Hepatitis B Viraemia Levels in Patients with HBeAg-negative Chronic Hepatitis B Virus Infection(Sage Publications Ltd, 2012) Atay, A. E.; Seven, G.; Yalcin, K.; Pasa, S.; Degertekin, H.OBJECTIVES: To evaluate patients with chronic hepatitis B virus (HBV) infection and low-level viraemia in terms of determining HBV DNA cut-off values and levels of alanine aminotransferase (ALT) and other possible markers for discriminating between chronic hepatitis B e-antigen (HBeAg)-negative patients and hepatitis B surface antigen (HBsAg) inactive carriers. METHODS: HBV-infected patients who were HBeAg-negative with undetectable HBV DNA by standard hybridization assay and high (HBeAg-negative group, n = 81) or normal (HBsAg inactive carrier group, n = 77) ALT levels were enrolled. Quantitative polymerase chain reaction assay using a COBAS Amplicor HBV monitor test was performed to detect low HBV DNA levels. RESULTS: The HBV DNA level was found to be significantly higher in the HBeAg-negative chronic HBV group (mean +/- SD 94 477 +/- 167 528 copies/nil) compared with the HBsAg inactive carrier group (mean +/- SD 19 215 +/- 57 970 copies/ml). CONCLUSIONS: A low level of viral replication may persist in chronic HBV-infected patients who are HBeAg-negative, and the level of HBV DNA was higher in the HBeAg-negative group than in the inactive HBsAg carrier group. Necroinflammation also persisted in the HBeAg-negative group and these patients had a higher level of ALT than the inactive HBsAg carriers.Öğe Hirsutism Score and the Severity of Hyperandrogenism Associated with Polycystic Ovary Syndrome in the South-eastern Region of Turkey(Sage Publications Ltd, 2011) Demir, B.; Pasa, S.; Demir, S.; Tumer, C.; Atay, A. E.; Gul, T.; Atamer, Y.This study investigated the severity of hirsutism and its correlation with serum total testosterone (tT) levels in 87 patients with polycystic ovary syndrome (PCOS) and 85 healthy control subjects from the south-eastern region of Turkey. A wide range of variability exists in both hirsutism and modified Ferriman-Gallwey (mFG) scores. Similar mFG scores and serum tT levels were found compared with previous studies of general populations, but lower scores than those previously reported from Turkey. The incidence of hirsutism was lower in hyperandrogenic PCOS patients compared with nonhyperandrogenic PCOS patients. There was no correlation between serum tT levels and the rate of hirsutism in patients with PCOS. Heritability, testosterone receptor sensitivity, 5 alpha reductase activity or environmental/socioeconomic factors may play a role in the development of clinical hirsutism. Larger scale studies are needed to clarify which other factors may be responsible and to confirm these results.Öğe Morphologic and functional vascular alterations in patients with polycystic ovary syndrome(I R O G Canada, Inc, 2011) Demir, B.; Pasa, S.; Demir, S.; Buyukkaya, R.; Atay, A. E.; Atamer, Y.; Gul, T.Background: We aimed to investigate morphologic and functional alterations of common carotid arteries (CCA) and femoral arteries and the anteroposterior diameter of the abdominal aorta in patients with polycystic ovary syndrome (PCOS). Materials and Methods: Fifty consecutive females with the complaint of oligoamenorrhea, infertility or hirsutismus, diagnosed with PCOS and 50 healthy females admitted to the Department of Gynecology and Obstetrics, Ergani State Hospital between January 2010 and January 2011 were included in the study. Results: The mean BMI of 50 patients with PCOS was higher than control subjects (CS) (25.89 +/- 3.3 vs 22.52 +/- 2.7 kg/m(2), p < 0.0001). The mean arterial blood pressure was 88.93 +/- 6.4 mmHg in the patient group and was it 85.73 +/- 7.6 mmHg in CS (p = 0.02). The mean plasma glucose level (74.04 +/- 6.7 vs 70.5 +/- 6.4 mg/dl), total cholesterol level (167.88 +/- 30.1 vs 153.38 +/- 27.8 mg/di), low density lipoprotein level (101.28 +/- 27.0 vs 79.56 +/- 25.5 mg/dl) and triglyceride level (121.22 +/- 49.2 vs 102.54 +/- 36.6 mg/di) were higher; also the mean high density lipoprotein level (44.56 +/- 8.1 vs 50.90 +/- 12.3 mg/dl) was lower in patients with PCOS than CS (p = 0.009, p = 0.014, p < 0.0001, p = 0.034 and p = 0.003, respectively). CCA-IMT (0.63 +/- 0.2 vs 0.52 +/- 0.1 mm), and CCA-PI (1.44 +/- 0.3 vs 1.28 +/- 0.22) were higher in patients with PCOS (p = 0.018 and p = 0.005, respectively). Femoral-IMT (0.62 +/- 0.6 vs 0.41 +/- 0.1 mm) and anteroposterior diameter of the infrarenal aorta (12.34 +/- 1.5 vs 11.4 +/- 1.0 mm) were higher in patients with PCOS (p = 0.024 and p = 0.001, respectively). Conclusion: The present study showed that IMT and PI of CCA, and anteroposterior diameter of the infrarenal abdominal aorta and femoral-IMT were higher in patients with PCOS. These results are probably related with increased androgens, their effects on insulin resistance and lipid profile, increased BMI and blood pressure. Detection of these functional and/or structural abnormalities are important in predicting prognosis. Larger scale prospective studies are needed to determine the effects of PCOS on the mortality and morbidity, and to clarify the relation between the duration of the disease and development of these alterations.Öğe Role of p53 codon 72 polymorphism in chromosomal aberrations and mitotic index in patients with chronic hepatitis B(Assoc Bras Divulg Cientifica, 2012) Akbas, H.; Yalcin, K.; Isi, H.; Tekes, S.; Atay, A. E.; Akkus, Z.; Budak, T.Polymorphisms of the p53 gene, which participates in DNA repair, can affect the functioning of the p53 protein. The Arg and Pro variants in p53 codon 72 were shown to have different regulation properties of p53-dependent DNA repair target genes that can affect various levels of cytogenetic aberrations in chronic hepatitis B patients. The present study aimed to examine the frequency of chromosomal aberrations and the mitotic index in patients with chronic hepatitis B and their possible association with p53 gene exon 4 codon 72 Arg72Pro (Ex4+ 119 G>C; rs1042522) polymorphism. Fifty-eight patients with chronic hepatitis B and 30 healthy individuals were genotyped in terms of the p53 gene codon 72 Arg72Pro polymorphism by PCR-RFLP. A 72-h cell culture was performed on the same individuals and evaluated in terms of chromosomal aberrations and mitotic index. A high frequency of chromosomal aberrations and low mitotic index were detected in the patient group compared to the control group. A higher frequency of chromosomal aberrations was detected in both the patient and the control groups with a homozygous proline genotype (13 patients, 3 control subjects) compared to patients and controls with other genotypes [Arg/Pro (38 patients, 20 control subjects) and Arg/Arg (7 patients, 7 control subjects)]. We observed an increased frequency of cytogenetic aberrations in patients with chronic hepatitis B. In addition, a higher frequency of cytogenetic aberrations was observed in p53 variants having the homozygous proline genotype compared to variants having other genotypes both in patients and healthy individuals.Öğe A simple way to estimate mean plasma glucose and to identify Type 2 diabetic subjects with poor glycaemic control when a standardized HbA1c assay is not available(Wiley, 2006) Ozmen, S.; Cil, T.; Atay, A. E.; Tuzcu, A. K.; Bahceci, M.Aims To evaluate the relationship between HbA(1c) and fasting plasma glucose (FPG) and postprandial plasma glucose (PPG) levels, and to estimate the mean plasma glucose (mPG) derived from FPG and PPG that would predict Type 2 diabetic subjects with poor glycaemic control. Methods FPG, PPG and HbA(1c) values from 565 Type 2 diabetic patients (247 men and 318 women) were recorded. Linear regression analysis and Pearson's correlation was used to determine the relationship between HbA(1c), FPG and PPG. FPG and PPG were included as explanatory variables of HbA(1c) in linear regression analysis. Results The American Diabetes Association's objective of achieving an HbA(1c) level < 7.0% was obtained in 26.2% of the patients. The coefficients of FPG and PPG which determined HbA(1c) were similar. Therefore, mPG was calculated using the equation (FPG + PPG)/2. Pearson's correlation coefficient for HbA(1c) and FPG, PPG and mPG were 0.723 (P < 0.0001), 0.734 and 0.761 (P < 0.0001), respectively. A mPG cut-off value of 10 mmol/l predicted an HbA(1c) > 7% in the whole population, with a sensitivity of 84.2% and specificity of 80.4%. The area was high (0.90) in receiver-operating characteristic (ROC) curve analysis performed to examine the performance of mPG to predict HbA(1c) > 7%. Conclusions The mPG derived from FPG and PPG correlates strongly with HbA(1c). We therefore suggest that using a cut-off of 10 mmol/l for mPG may be appropriate in diabetes management in the primary-care setting, where most management of Type 2 diabetes occurs.Öğe Tubo-ovarian abscess presenting as an ovarian tumor in a virginal adolescent: a case report(I R O G Canada, Inc, 2012) Sakar, M. N.; Gul, T.; Atay, A. E.Tubo-ovarian abscess (TOA), a serious complication of pelvic inflammatory disease, unites the fallopian tube and ovary and, is rarely observed in sexually inactive adolescent girls. A pelvic mass, supposedly originating from the ovary, was detected in a 13-year-old sexually inactive girl suffering from abdominal pain and menstrual disorder. Pelvic ultrasonography pointed out a semisolid, hyperechogenic mass of 57 x 73 mm in the left adnexal area. Laparotomy revealed an unilateral TOA adhering to the bowel and omentum. Abscess drainage and adhesiolysis were performed and postoperative antibiotherapy was administered. TOA should be considered in the differential diagnosis of females with abdominal pain and adnexal mass whether sexual activity is present or not.Öğe Urticaria and hydropneumothorax as an exceptional cause of ruptured hydatid cyst of lung(Wolters Kluwer Medknow Publications, 2013) Atay, A.
