Background: This study aimed to determine nursing student knowledge, behavior and beliefs for breast cancer and breast self-examination receiving courses with a traditional lecturing method (TLM) and the Six Thinking Hats method (STHM). Materials and Methods: The population of the study included a total of 69 second year nursing students, 34 of whom received courses with traditional lecturing and 35 of whom received training with the STHM, an active learning approach. The data of the study were collected pre-training and 15 days and 3 months post-training. The data collection tools were a questionnaire form questioning socio-demographic features, and breast cancer and breast self-examination (BSE) knowledge and the Champion's Health Belief Model Scale. The tests used in data analysis were chi-square, independent samples t-test and paired t-test. Results: The mean knowledge score following traditional lecturing method increased from $9.32{\pm}1.82$ to $14.41{\pm}1.94$ (P<0.001) and it increased from $9.20{\pm}2.33$ to $14.73{\pm}2.91$ after training with the Six Thinking Hats Method (P<0.001). It was determined that there was a significant increase in pre and post-training perceptions of perceived confidence in both groups. There was a statistically significant difference between pre-training, and 15 days and 3 months post-training frequency of BSE in the students trained according to STHM (p<0.05). On the other hand, there was a statistically significant difference between pre-training and 3 months post-training frequency of BSE in the students trained according to TLM. Conclusions: In both training groups, the knowledge of breast cancer and BSE, and the perception of confidence increased similarly. In order to raise nursing student awareness in breast cancer, either of the traditional lecturing method or the Six Thinking Hats Method can be chosen according to the suitability of the teaching material and resources.

Awareness and Practices Regarding Breast and Cervical Cancer among Turkish Women in Gazientep
Karadag, Gulendam,Gungormus, Zeynep,Surucu, Ramazan,Savas, Esen,Bicer, Fulya Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.3
Background: Cancer is a major public health problem both in our country and worldwide due to its disease burden, fatality and tendency for increased incidence. In Turkey, breast cancer ranks first with an incidence of 41.6% and cervical cancer is the tenth most common cancer with an incidence of 4.4%. Objectives and Design: This descriptive, cross-sectional study was conducted with 240 women aged from 15 to 65 years admitted to a gynecology-obstetrics outpatient clinic of a private hospital in Gaziantep. Study data were collected by the investigators through a 36-item questionnaire form which was generated using information gathered from similar surveys in the literature. Results: It was determined that 34.6% of women were high-school graduates, and 64.2% had a medium income level. The majority (79.2%) stated that they never performed BSE and 49.5% of them said that they did not know how to do it. Some 79.2% did not know what a Pap smear was and 73.3% had not experienced a smear test ever. Conclusions: In this study, we found that most of the women had insufficient knowledge of breast and cervical cancer, while knowledge and practices increased with the education level. Based on these findings, we suggest that there is a need for planning, implementation and assessment of health policies and healthcare services at the national and regional level and we believe that nurses working in the field of protective health services should develop educational programmes for women with a primary focus on cancer in order to increase awareness among the female population in Turkey.

Karadag, Burak,Kocak, M.,Kayikcioglu, F.,Ercan, F.,Dilbaz, B.,Kose, M.F.,Haberal, A. Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19
Objective: To verify the basic preoperative evaluation in the discrimination between benign and malignant adnexal masses in our clinical practice. Materials and Methods: Data were collected on the records of 636 women with adnexal masses who had undergone surgery either by open or endoscopic approaches. Those with obvious signs of malignancy, any history of cancer, emergency surgeries without basic evaluation were excluded. The preoperative features by age, ultrasound and serum Ca125 level were compared with final histopathological diagnosis at the four departments of the institution. These are the general gynecology (Group 1: exploratory laparotomy), the gynecologic endoscopy (Group 2: laparoscopy and adnexectomy), the gynecological oncology (Group 3: staging laparotomy) and the gynecologic endocrinology and infertility (Group 4: laparoscopy and cystectomy). Results: There were simple and complex cyst rates of 22.3% and 77.2%, respectively. There were 86.3% benign, 4.1% (n:20) borderline ovarian tumor (BOT) and 6.4% (n:48) malignant lesions. There were 3 BOT and 9 ovarian cancers in Group 1 and one BOT and two ovarian cancer in the Group 2. During the surgery, 15 BOT (75%) and 37 ovarian cancer (77%) were detected in the Group 3, only one BOT was encountered in the Group 4. The risk of rate of unsuspected borderline or focally invasive ovarian cancer significantly increased by age, size, complex morphology and Ca125 (95% CI, OR=2.72, OR=6.60, OR=6.66 and OR=4.69, respectively). Conclusions: Basic preoperative evaluation by comprehensive ultrasound imaging combined with age and Ca125 level has proved highly accurate for prediction of unexpected malignancies. Neither novel markers nor new imaging techniques provide better information that allow clinicians to assess the feasibility of the planned surgery; consequently, the risk of inadvertent cyst rupture during laparoscopy may be significantly decreased in selected cases.

Post-Traumatic Pneumocele of the Frontal Sinus
Demet Karadag,Cuneyt Calisir,Baki Adapinar 대한영상의학회 2008 Korean Journal of Radiology Vol.9 No.4
A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

In this meta-analysis study, different leadership approaches were combined, and the relationship between educational leadership and student achievement was analyzed. In the literature review, 151 research articles/dissertations, independent from one another, were brought together, and 131,498 study subjects were included in the sample group. The results of the analyses performed with a random effects model revealed that educational leadership has a medium-level effect on students’ achievement. Educational leadership has comprehensive effect on student achievement in vertical-collectivist cultures (e.g., in Asian) than horizontal-individualistic cultures (e.g., in USA). As was expected, the most comprehensive effect among leadership theories was found in instructional leadership. Considering the effect of educational leadership on students’ achievement, it is recommended to examine the effect of leadership on other components of school and stakeholders in future studies.

Background: Hydroxychloroquine(HQ) is widely used to treat for rheumatoid arthritis( RA) and connectice tissue disorders. Due to the potential of ocular toxicity,routine ophtalmological assessment(ROA) is essential for sight safety. Methods: In our outpatient clinic, patients with RA and connective tissue disorders such as systemic lupus erythematosus (SLE), sjogren syndorme (SS) and overlap were assessed consecutively for drug status of HQ by a standard questionnaire between December 2013 and January 2014. Patients who used HQ less than 1 year (13. 6%) were excluded from study. Ocular toxicity was taken from patients` reported. If ophthalmologist advised to cease HQ due to ocular toxicity,we accepted as ocular side effect. Patients with ocular toxicity were not reevaluated by an ophthalmologist. Cumulative HQ dosage and risk factors for ocular toxicity were assessed by using Mann-Whitney U test. Results: A total of 266 patients(90. 6% female) were enrolled. Mean age was 50±13. 5 years and median disease duration was 8 years(1-50). Median duration of HQ treatment was 6 years(1-28) and median dose was 400 mg/day. Of 46(17. 3%) patients were ceased HQ. The reasons of cease of HQ were ocular toxicity 22(47. 8%), patient non-adherence 9(19. 6%),dermatological side effect 3(6. 5%),others 12(26. 1%). 22 of all 266(%8. 3) patients developed ocular toxicity. Ocular toxicity was found more frequently in male 5/20(20%) vs 17/241(7%),p=0. 025). Median cumulative HQ dosage in patients with ocular toxicity was 864 gram (108-2160) in other words 12. 9 gr per kilogram( 1. 2-40). Older age (58±10 vs 50±13,p=0. 008),longer disease duration (14. 8±11. 5 vs 9. 2±7. 1 years,p=0. 013), and longer HQ duration (10±6. 3 vs 7. 1±5. 6 years,p=0. 023)were associated with ocular toxicity. Conclusions: Among regularly follow-up patients, ocular toxicity of HQ was not rare in a rheumatology outpatient clinic. Cumulative toxicity for ocular toxicity was 13 gram/kilogram;however, certain patients developed toxicity in 1 gram/kg/day. Although, important part of our patients was female, ocular toxicity was seen more frequently in male patients. Other risk factors such as longer disease duration,longer HQ usage and older age were also demonstrated in our patients.

Objective: We investigated the relationship between serum bilirubin levels and metabolic syndrome (MetS), and the longitudinal effects of baseline serum bilirubin concentrations on MetS in patients with schizophrenia spectrum disorders undergoing atypical antipsychotics. Methods: The sample of this study consisted of 131 patients with schizophrenia spectrum disorders. Waist circumference, blood pressure, and levels of triglycerides, high-density lipoprotein cholesterol, fasting glucose, and insulin were evaluated at baseline and at month six. Serum bilirubin levels were measured at baseline. Serum bilirubin levels of the patients with and without MetS criteria were compared. We also compared patients with high and low bilirubin levels (upper and lower 50th percentiles of serum bilirubin levels) in terms of MetS criteria, MetS frequency, and course of MetS. Results: Serum direct bilirubin levels were more consistently related to MetS and MetS-related variables. The waist circumference and triglyceride criteria for MetS were significantly related to low serum direct bilirubin at baseline; waist circumference and fasting glucose criteria, and insulin resistance were associated with low serum direct bilirubin at follow-up. MetS diagnosis and the presence of the waist circumference criterion were more frequent at the baseline and the follow-up in low bilirubin group. At the end of the follow-up period, the rate of reverse MetS was significantly higher in the high bilirubin group. Conclusion: Our results have suggested that serum direct bilirubin levels showed a more reliable and stable relationship with abdominal obesity for MetS components.in patients with schizophrenia spectrum disorders using antipsychotics. Further studies are required.
