p-ANCA and c-ANCA frequency and their relationship with other diseases in patients with lung cancer
Ahmet Ylmaz,Hatice Ylmaz
Journal of Clinical and Experimental Investigations , 2011,
Abstract: Objectives: In this study, we aimed to investigate the association of cancer with vasculitis and the frequency of cancer-related paraneoplastic syndromes and their relationship by measuring blood levels of Perinuclear type Anti-Neutrophilic Cytoplasmic Antibody (p-ANCA) and Cytoplasmic type antineutrophil cytoplasmic antibodies (c-ANCA) in patients with lung cancer and asthma and in healthy individuals.Materials and methods: 20 patients diagnosed with asthma, 26 patients following up with a diagnosis of lung cancer and control group of 20 healthy individuals were enrolled in this study. ANCA levels were measured in blood samples.Results: Borderline positive c-ANCA detected in 1 of 26 patients and 1/32 percent were positive detected in one patient. Borderline positive p-ANCA detected in 1 of 26 patients and 1/32 percent were positive detected in 1 patient. p-ANCA was positive detected in 2/20 of asthmatic patient and c-ANCA was borderline positive detected in 1/20 asthma patient. In asthma and cancer patients, physical examinations and pathological findings did not support the vasculitis. Only one subject in the control group was found to be borderline positive for c-ANCA.Conclusion: As a result, in some of the patients the positivity of ANCA was detected not related with vasculitis and paraneoplastic findings. Because of this, vasculitis should be considered in differential diagnosis of the patients whom considered as malignancy.

Journal of Clinical and Experimental Investigations , 2011,
Abstract: Objectives: Regional studies of diabetes mellitus (DM) are important to determine of effective environmental factors in the development of DM and defining strategy against these factors. This study aims to define the frequency of DM prevalence in the province of the Van city, distribution of DM according to age groups, effective socio-economical, geographical and metabolic factors over the diabetes development.Material and methods: This study included 191 male and 209 female totals 400 person aged year 16 years or over. Blood-Glucose levels of persons were measured with Accu-check glucometer and questionnaires were filled with face-to-face interviews.Results: Age mean of subjects was 35.09±13.75 years, DM prevalence was %13.4 between the females and %9.1 males, disglisemi (DG) prevalence were %9.1 between the females and %5.8 between the males. 74.4% of impaired glucose metabolism persons were people who they do not make physical exercise and adopted sedentary lifestyle.Conclusion: In this study, age and family history from unchangeable factors were found to be effective on the development of DM but sex, educational level, social security, incomes were not found to be effective on development of DM. Exercise, blood pressure levels, obesity and diets from changeable factors are the factors that influence the frequency of DM was determined in this study. J Clin Exp Invest 2011; 2 (4): 392-399
EMPIRICAL INVESTIGATION ON GLOBALIZATION AND SOCIAL POLARIZATION: CROSS COUNTRY ANALYSIS
Aylin Ko?,Ahmet Ylmaz Ata,Zeynep ?irkin
International Journal of Economics and Financial Issues , 2013,
Abstract: It is considered that the integration process of both developed and developing countries with the global world affects the aspect of social polarization in these countries. Two main approaches which are different from each other exist in the related literature about the effects of globalization on the social polarization. The first approach, which is mostly supported by neo-liberal economists, claims that the globalization influences the social polarization positively. The other approach suggests that the social polarization increases in the economies together with the globalization process. With this study which was prepared in this scope, the effect of globalization process on the social polarization was tried to be tested by cross-sectional analysis of the data of 2008 of twenty-seven EU member countries. As a result of the findings obtained in this study, it was concluded that the globalization process has a decreasing effect on the social polarization in these countries.

Turk Toraks Dergisi , 2012,
Abstract: Objective: We investigated the levels of anxiety, depression and quality of life of non small cell lung cancer (NSCLC) patients receiving chemotherapy. Material and Method: Forty three patients with NSCLC cancer receiving chemotherapy were included in this study. The series of forms including the questions regarding the demographic characteristics of the patients, Turkish version of the Beck Depression Inventory (BDI), the Turkish version of the State-Trait Anxiety Inventory (STAI) and EORTC- QLQ-C30 (version 3) were completed during face-to-face interviews by trained interviewers to determine the psychological status and quality of life of the patients.Results: The mean Beck depression scores were 18±10.1 (range 0-40) and the mean STAI scores were 46.2±6.6 (range 33-60). 46.5% of the patients (20 patients) (Beck Depression scores ≥17 points) were determined as depressive. The STAI and EORTC-QLQ C30 symptom scales scores (excluding the dyspnea, diarrhea, constipation, appetite loss and financial problems) of the depressive patients (BDI≥17) were significantly higher than that of the non depressive patients (BDI<17). On the other hand, the EORTC-QLQ C30 function scales (physical, role, cognitive, emotional and social function scales) and global quality of life scores of the depressive patients (BDI≥17) were significantly lower than that of the non depressive patients (BDI<17). Conclusion: In our study, anxiety and depression levels were high in Turkish NSCLC cancer patients. We found that depression was strongly associated with the poor quality of life in Turkish NSCLC cancer patients.

Turkderm , 2010,
Abstract: Neurofibromatosis is a group of clinically related systemic disorders characterized by autosomal dominant inheritance. Hypophosphatemia may rarely develop due to phosphorus loss in the urine in a patient with neurofibromatosis type 1. We present here a 42-year-old male patient with neurofibromatosis type 1, who has two-year history of bone pain and fatigue. Hypoproteinemia, very low blood phosphorus level, significant reduction in bone mineral density, and insufficiency fractures of the proximal femurs and left fibula were detected. It was considered that hypophosphatemic osteomalacia led to stress fractures. The fractures were sufficiently healed with bisphosphonate, vitamin D, calcium treatment and phosphorus-rich diet. The blood phosphorus level of the patient approached approximately the normal limits. Long-lasting spinal, arm and leg pain in patients with neurofibromatosis type 1 must be carefully followed. It should be kept in mind that hypophosphatemic osteomalacia may occur in these patients. In addition to systemic examination, measurement of blood phosphorus level and bone mineral density must be done in order to prevent severe morbidities.

Safiye Ylmaz,Aras Saklamaz,Serkan Da?delen,Ahmet Maden
Erciyes Medical Journal , 2007,
Abstract: Purpose: It was aimed to report the outcome of secondary intraocular lens implantation performed for aphakia.Methods: Forty eyes of 35 patients which were administered to our institution for aphakia between January 2002 and December 2003, were included. Secondary intraocular lens implantation was performed in all patients. Change in visual acuity, refraction, intraocular pressure and the position of intraocular lens were evaluated before and after the operation.Results: The average age of the patients (17 men and 18 women) was 43.3±23.59 years. While thirty-two eyes had inadequate posterior capsular support, eight eyes had adequate capsular support. The sites of fixation of implanted intraocular lenses were as follows: Sulcus (n=8) and transsclerally fixated (n=32). Preoperative visual acuity was 0.29±0.22, whereas it was 0.5±0.29 postoperatively. Intraocular pressure was 14.75±2.08 mmHg preoperatively and 15.93±1.73 mmHg postoperatively. The spherical equivalent was 10±1.36 preoperatively and 1.82±0.85 postoperatively. Complications encountered after the implantation were clinically significant intraocular lens decentration (2-5%), visual axis opacification (3-7.5%), intraocular lens dislocation (2-5%), and pupillary capture (1-2.5%), transient anterior chamber or vitreous hemorage (5-12.5%), subconjonktival hemorage (6-15%).Conclusion: Secondary intraocular lens implantation can be safely achieved in aphakic eyes, since no permanent vision threatened complication was seen following the surgery.

Computer Science , 2014,
Abstract: We used Lemur Toolkit, an open source toolkit designed for Information Retrieval (IR) research, for our automated indexing and retrieval experiments on a TREC-like test collection for Turkish. We study and compare three retrieval models Lemur supports, especially Language modeling approach to IR, combined with language specific preprocessing techniques. Our experiments show that all retrieval models benefits from language specific preprocessing in terms of retrieval quality. Also Language Modeling approach is the best performing retrieval model when language specific preprocessing applied.

Turk Pediatri Ar?ivi , 2010,
Abstract: Acute bronchiolitis is a disease characterized with bronchiolar inflammation due to viral infections in children younger than two years that is associated with wheezing, cough, tachypnea, retractions and prolonged expiration. Many pathogens, among which respiratory syncytial virus is the most common, play role in the etiology. Cellular damage due to viral pathogens and anatomic and immunological factors of the host play a role in the development of lower respiratory tract infections only in some children exposed to respiratory syncytial virus and other viruses. Viral infections in children may change Th1/Th2 immune response pattern. Severity of disease changes with the degree of inflammation due to the immune response. Moreover, an increase in disease severity may be observed due to the activation of the non-adrenergic non-cholinergic neurogenic system. Severe RSV infections may develop in children with genetic predisposition. We explained the role of environmental factors, genetic and structural susceptibility of the host, and contribution of immunologic response in this susceptibility, in addition to the role of responsible infectious agents, in the development and severe progression of bronchiolitis (Turk Arch Ped 2010; 45: 75-81)
