    BACKGROUND: In a previous report, we hypothesized that responses to placebo were high in child and adolescent depression because of specific psychopathological factors associated with youth major depression. The purpose of this study was to compare the placebo response rates in pharmacological trials for major depressive disorder (MDD), obsessive compulsive disorder (OCD) and other anxiety disorders (AD-non-OCD). METHODOLOGY AND PRINCIPAL FINDINGS: We reviewed the literature relevant to the use of psychotropic medication in children and adolescents with internalized disorders, restricting our review to double-blind studies including a placebo arm. Placebo response rates were pooled and compared according to diagnosis (MDD vs. OCD vs. AD-non-OCD), age (adolescent vs. child), and date of publication. From 1972 to 2007, we found 23 trials that evaluated the efficacy of psychotropic medication (mainly non-tricyclic antidepressants) involving youth with MDD, 7 pertaining to youth with OCD, and 10 pertaining to youth with other anxiety disorders (N = 2533 patients in placebo arms). As hypothesized, the placebo response rate was significantly higher in studies on MDD, than in those examining OCD and AD-non-OCD (49.6% [range: 17-90%] vs. 31% [range: 4-41%] vs. 39.6% [range: 9-53], respectively, ANOVA F = 7.1, p = 0.002). Children showed a higher stable placebo response within all three diagnoses than adolescents, though this difference was not significant. Finally, no significant effects were found with respect to the year of publication. CONCLUSION: MDD in children and adolescents appears to be more responsive to placebo than other internalized conditions, which highlights differential psychopathology

    What happens when men are the subjects of research? Gender and other forms of social difference are performed and negotiated in part through face-to-face interactions, including through such research methods as interviews and focus groups. When men or women conduct gender-conscious research with male research subjects, a host of issues are raised: practical, political and epistemological. This chapter explores three dimensions of face-to-face research among men

    Evaluating clonidine response in children and adolescents with attention-deficit/hyperactivity disorder

    Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in childhood, which is generally treated with stimulant and non-stimulant medications. However, 10-30% of patients in clinical setting do not present with adequate response to initial stimulant treatment. Thereby, clonidine may be considered for those patients who have failed to respond to psychostimulant/atomoxetine monotherapy or as an augmentation for inadequate response/comorbidity. This observational study evaluated its effectiveness as a single drug in ADHD cases unresponsive to previous treatment trials. Seventeen ADHD cases that were non-responders to stimulant, non-stimulant and combination therapy for the primary symptoms of ADHD were included in the study. Four cases dropped out before follow up, leaving thirteen cases who were administered immediate release clonidine treatment alone with a mean dose of 0.2 +/- 0.05 mg/day at baseline. The trial lasted for 12 weeks, and treatment outcomes were evaluated by the Turgay DSM-IV Based Child and Adolescent Behavior Disorders Screening and Rating Scale (T-DSM-IV-S) and the Clinical Global Impressions-Severity (CGI-S) and Improvement (CGI-I) scales. Mean age of the sample was 12.5 years (SD = 3.0) and eleven of the subjects had another comorbid psychopathology. Only two cases were evaluated as "very much improved", while another patient was judged to be "minimally improved" after 12 weeks of clonidine treatment. Attrition during follow-up was associated with higher median scores on the hyperactivity and impulsivity subscales (Mann-Whitney U test, p = 0.02). According to the T-DSM-IV-S, CGI-S, and CGI-I scales, clonidine treatment by itself had minimal benefits in this sample of treatment of refractory cases with ADHD evaluated at the study center. Clonidine is not available in Turkey pharmaceutical marketing system and patients' access to drug is limited. Our results provide first data regarding the use of clonidine in Turkish ADHD patients
