Prevalence of Allergic Rhinitis in Children in the Trabzon Province of the Black Sea Region of Turkey

Objective: We aimed to determine the prevalence of allergic rhinitis in children aged 12-15 years who lived in the Trabzon Province, specify possible risk factors, and compare the data obtained with those of the other studies conducted in our country and in other countries.Methods: First, 1372 students from nine primary schools determined according to the recommendations of Department of Public Health and approval of The Provincial Directorate of Health were screened in their schools with questionnaire forms. Second, students providing the response “yes” to the first and/or second questions in the questionnaire forms were considered as possible allergic rhinitis patients and invited to our clinic. Then, 246 students were subjected to a skin prick test. Data were collected with the evalution of questionnaire and skin prick test results together.Results: The prevalance of allergic rhinitis in children between 12 and 15 years age was found to be 14.5% in Trabzon. Female gender was found to be a relative a risk factor for allergic rhinitis (p=0.015). The prevalence of allergic rhinitis in children whose both parents were smoking was significantly higher than that in children whose only one parent was smoking or both parents were nonsmokers (p=0.0024). In addition, living in an apartment flat (p=0.015) and owing pets (p=0.04) were detected to be other risk factors for allergic rhinitis.Conclusion: According to our investigations, this is the first prevalence study in Trabzon, which is the largest settlement in the Eastern Black Sea Region. The prevalence of allergic rhinitis in children was found to be 14.5%. Female gender, smoking habits of the parents, owing pets, and living in an apartment flat are risk factors for allergic rhinitis

Viskoz olmayan kesme tabakasının doğrusal kararlılık teorileri ile incelenmesi

ThisIn this thesis, spatial and temporal instabilities of the inviscid shear layer flows are investigated using the linear stability theory. Utilizing the small and wavy disturbances, Rayleigh equation was derived from the Helmholtz vorticity equation. For the hyperbolic-tangent velocity profile, the Rayleigh equation was solved by using space and time amplification approaches by an in-house Fortran code involving RK4 and simplex method algorithm. Eigenvalues of various disturbance frequencies were calculated both for spatial and temporal amplification theories. Results of two theories were compared and the most strongly amplified disturbance frequencies were calculated. Eigenfunctions of spatial theory were plotted for various disturbance frequencies. For the most strongly amplified disturbance frequency, eigenfunctions were calculated for both theories and compared. In spatial amplification case, derivatives of the eigenfunctions and the vorticity amplitudes were also calculated for different disturbance frequencies. By using the vorticity amplitudes, constant vorticity distributions of spatial amplification were plotted at different times in order to demonstrate the mechanism of instability. At the most strongly amplified disturbance frequency of spatial theory, the motion of particles at different locations in the shear layer were investigated. To investigate the motions of the particles and the characteristics of the instability clearly, the pathlines and the streaklines of the disturbed shear layer were calculated and the streakline patterns were drawn. The pathlines and streaklines were also compared in terms of their ability to reflect the instability mechanism. The streaklines of the shear layer at different disturbance frequencies were compared. Results calculated by the help of the Fortran code were compared with experimental and numerical data in the literature and seen that they are in agreement. The Fortran code was also tested with the different velocity profiles to check its capability. The reasons why the code could not solve the parabolic velocity profiles were discussed.M.S. - Master of Scienc

Salvage excavations of the Afyon archaeological museum, part 2 : the settlement of Karaoğlan Mevkii and the Early Bronze Age cemetery of Kaklık Mevkii

This article deals with the salvage excavations of the Afyon Archaeological Museum at Karaoğlan Mevkii and Kakhk Mevkii in the north of the province. Here the EB 2 and EB 3 material from the cemetery at Kakhk Mevkii is considered, as well as the finds from the EB 2 settlement at Karaoğlan Mevkii. The settlement, which corresponds to the second half of the EB 2 period, demonstrates a single cultural continuum comprised of two —or possibly three — architectural subphases. It is encircled by an impressive fortification wall replete with towers and buttresses. The layout of the settlement, although only partially excavated, reflects a somewhat degenerate version of the Anatolisches Siedlungsschema revealed at Demircihüyük. The pottery displays the characteristics of (and better defines) the 'Afyon EB 2 pottery group', previously recognized only through surface survey. The graves at Kakhk Mevkii were found in two clusters (in Area A and in Area B), dug into the early EB 1 settlement treated in Part 1 . The graves fall chronologically into three groups. The earliest graves are the cists and pithos burials found in Area B, roughly contemporary with the settlement at Karaoglan Mevkii. A second group, concentrated in Area A, consists of pseudo-chamber tombs and simple inhumations from the very beginning of the EB 3 period. The latest graves are simple inhumations from mid-EB 3 times. The material from this cemetery — particularly considering the analogies between the finds here and those from the Demircihüyük-Sanket and Karatas/Semayük cemeteries— represents a significant contribution to the EBA chronology of inland western Anatolia.Topbaş Ahmet, Efe Turan, İlaslı Ahmet.

Evaluation of right side foetal myocardial performance index in pregestational and gestational diabetes mellitus

The aim of our study is to investigate the myocardial performance index (MPI) of the right side of the foetal heart in pregestational and gestational diabetes mellitus and to compare it with non-diabetic pregnancies. This prospective cross-sectional study was conducted between August 2018 and March 2019 at Kanuni Sultan Suleyman Research and Training Hospital. Women with pregestational or gestational diabetes mellitus at 24-34 weeks of gestation were included in the study and non-diabetic pregnant women were included as the control group. MPI of the right side of the foetal heart were evaluated and compared between the groups. A total of 65 pregestational or gestational diabetic patients and 65 non-diabetic patients were included in the study. Isovolumetric contraction time and isovolumetric relaxation time values were significantly longer in the diabetic group (p < .001). Ejection time values were significantly shorter in the diabetic group (p < .001). MPI values were significantly higher in the diabetic group than the non-diabetic group (p < .001). In conclusion, MPI of the right side of the foetal heart is significantly higher in pregestational and gestational diabetes than in the non-diabetic group.IMPACT STATEMENT What is already known on this subject? Gestational diabetes mellitus causes foetal cardiomyopathy and foetal diastolic dysfunction. Myocardial performance index (MPI) is a non-invasive, Doppler-derived myocardial performance assessment that is independent of both heart rate and ventricular anatomy. What do the results of this study add? MPI of the right side of the foetal heart was significantly higher in pregestational and gestational diabetes than in the non-diabetic group. There was no difference in right ventricular MPI between pregestational and gestational groups in diabetic pregnancies, and between insulin using and not insulin using groups. What are the implications of these findings for clinical practice and/or further research? Our study results are promising. MPI of the right side of the foetal heart is significantly higher in pregestational and gestational diabetes than in the non-diabetic group. Prospective cohort studies evaluating serial MPI and evaluating by postpartum foetal echocardiography are needed to evaluate possible adverse effects of diabetes on foetal cardiac functions
