    Aim: To determine the prevalence of affective disorders in Turkey among a representative sample of Turkish population. Methods: This study was conducted as a part of the The Epidemiology of Childhood Psychopathology in Turkey (EPICPAT-T) Study, which was designed by the Turkish Association of Child and Adolescent Mental Health. The inclusion criterion was being a student between the second and fourth grades in the schools assigned as study centers. The assessment tools used were the K-SADS-PL, and a sociodemographic form that was designed by the authors. Impairment was assessed via a 3 point-Likert type scale independently rated by a parent and a teacher. Results: A total of 5842 participants were included in the analyses. The prevalence of affective disorders was 2.5 % without considering impairment and 1.6 % when impairment was taken into account. In our sample, the diagnosis of bipolar disorder was lacking, thus depressive disorders constituted all the cases. Among depressive disorders with impairment, major depressive disorder (MDD) (prevalence of 1.06%) was the most common, followed by dysthymia (prevalence of 0.2%), adjustment disorder with depressive features (prevalence of 0.17%), and depressive disorder-NOS (prevalence of 0.14%). There were no statistically significant gender differences for depression. Maternal psychopathology and paternal physical illness were predictors of affective disorders with pervasive impairment. Conclusion: MDD was the most common depressive disorder among Turkish children in this nationwide epidemiological study. This highlights the severe nature of depression and the importance of early interventions. Populations with maternal psychopathology and paternal physical illness may be the most appropriate targets for interventions to prevent and treat depression in children and adolescents.

    Platelet-activating factor and P-selectin activities in thrombotic and nonthrombotic Behcet's patients
    Tunc, SE; Aksu, K; Keser, G; Oksel, F; Doganavsargil, E; Pirildar, T; Turk, T; Terzioglu, E; Huseyinov, A
    Objective: The aim of this study was to compare plasma Platelet-activating factor (PAF) and P-selectin (CD62P) activities in Behcet's disease patients with and without thrombosis. Methods: In this cross-sectional and descriptive study, 30 consecutive Behcet's patients were included, 15 of them with venous thrombosis. All patients were also divided into two subgroups according to the presence or absence of clinical activity. Plasma PAF levels, basal and Ca++ ionophore (A23187)-induced leukocyte (cellular) PAF activities, and platelet-rich plasma Delta CD62P activity (the mean fluorescent density difference between CD62P phycoerythrin-positive and -negative stains) were evaluated. Results: In the thrombotic group, plasma PAF (P=0.001), basal leukocyte PAF (P=0.017), induced leukocyte PAF (P=0.024), and Delta CD62P (P=0.023) levels were significantly higher than in the nonthrombotic group. In the whole group of Behcet's patients, there was a positive correlation between plasma PAF and Delta CD62P levels (r=0.533, P=0.002). When we compared clinically active and inactive patients with respect to the above parameters, there was no significant difference, irrespective of thrombosis. Plasma PAF (P=0.001), basal leukocyte PAF (P=0.004), and Delta CD62P (P=0.038) levels were significantly higher in the presence of both clinical activity and thrombosis than of clinical activity alone. Conclusion: Platelet-activating factor and CD62P may contribute to endothelial injury and thrombosis development in Behcet's disease. These two parameters seem related to the presence of thrombosis rather than clinical activity.

    Nail changes in connective tissue diseases: do nail changes provide clues for the diagnosis?
    Tunc, SE; Ertam, I; Pirildar, T; Turk, T; Ozturk, M; Doganavsargil, E
    Objective To evaluate the frequency and the specificity of nail changes associated with connective tissue diseases (CTD). Methods In a case-control study, 190 patients including those with systemic lupus erythematosus (SLE; 56), rheumatoid arthritis (RA, 47), primary Sjogren's syndrome (pSS; 35), systemic sclerosis (SSc; 39), and dermatomyositis/polymyositis (DM/PM; 13) were enrolled in the study. Patients with SLE and other CTDs were compared with two different control groups. Twenty nails were examined. Nail features were noted and classified. Nail samples were collected for mycological cultures. Results In patients with SLE, erythema of proximal nailfold (P < 0.01), splinter haemorrhages in fingernails (P < 0.01), capillary loops in proximal nailfold (P < 0.05), periungual erythema (P < 0.05), and thin nail plates (P < 0.05) were more common than those in controls. Only splinter haemorrhages were associated with the disease activity. In patients with SSc and DM/PM, splinter haemorrhages (P < 0.05) and capillary loops in proximal nailfold (P < 0.01) in fingernails were common as well. Increase in longitudinal curvature (P < 0.001), transverse curvature (P < 0.01), and white dull colour in fingernails were other frequent findings in patients with SSc. Increase in transverse curvature was associated with the disease activity in SSc. In patients with RA, splinter haemorrhages (P < 0.05), red lunula (P < 0.05), and white dull colour (P < 0.05) in fingernails were frequent. The sensitivity values of all these changes were very low. However, their specificity values were found to be relatively high. Conclusion Proximal nailfold is the most important site of affection in CTDs. These nail changes can be used in combination with highly sensitive diagnostic modalities to establish an accurate diagnosis.
