Background: This study is concerned with relationships between childhood trauma history, dissociative experiences, and the clinical phenomenology of chronic schizophrenia. Sampling and Methods: Seventy patients with a schizophrenic disorder were evaluated using the Structured Clinical Interview for DSM-IV, Dissociative Experiences Scale, Dissociative Disorders Interview Schedule, Positive and Negative Symptoms Scales, and Childhood Trauma Questionnaire. Results: Childhood trauma scores were correlated with dissociation scale scores and dissociative symptom clusters, but not with core symptoms of the schizophrenic disorder. Cluster analysis identified a subgroup of patients with high dissociation and childhood trauma history. The dissociative subgroup was characterized by higher numbers of general psychiatric comorbidities, secondary features of dissociative identity disorder, Schneiderian symptoms, somatic complaints, and extrasensory perceptions. A significant majority of the dissociative subgroup fit the diagnostic criteria of DSM-IV borderline personality disorder concurrently. Among childhood trauma types, only physical abuse and physical neglect predicted dissociation. Conclusions: A trauma-related dissociative subtype of schizophrenia is supported. Childhood trauma is related to concurrent dissociation among patients with schizophrenic disorder. A duality model based on the interaction of 2 qualitatively distinct psychopathologies and a dimensional approach are proposed as possible explanations for the complex relationship between these 2 psychopathologies and childhood trauma.

The results indicated a significant association between Internet addiction and obesity. Health practitioners should take possible Internet addiction, online activities, and physical activities into consideration in follow-up of obese adolescents. In addition to pharmacologic therapies and dietary interventions, providing behavioral therapy targeting healthy Internet use may be promising to reduce the effects of obesity in adolescence.

Both chronic disease states affect psychology of children. Repeated anesthesia in addition to chronic disease does not seem to disturb the child's psychological health further when tentative and precautious approach modalities are undertaken.

Nomophobia refers to an intense anxiety and stress caused by being out of contact with mobile phones (MPs). It is known that excessive engagement with MPs decreases adolescents' psychological well-being, social and academic functioning. The aim of this study was to investigate the associations of nomophobia with alexithymia which is characterized by difficulties in describing and expressing emotions and using empathy, and with the metacognition characteristics which have the function of controlling the cognitions in an adolescent population. The study was conducted on 1817 participants (n = 972, 54% female, n = 835, 46% male). The Nomophobia Questionnaire (NMP-Q), The Twenty-Item Toronto Alexithymia Scale (TAS-20) and The Metacognition Questionnaire for Children and Adolescents (MCQ-C) were administered to participants. A question form for socio-demographic data was also administered to participants and their families. Cathegorical variables were analyzed by chi-square test, and numerical variables were analyzed by independent sample t test. The relationships between the scales' scores were analyzed by the Pearson-product moments correlation test. The predictive effects of alexithymia, metacognition problems and gender were assessed by multiple linear regression analysis. Nomophobia, alexithymia and metacognition problem levels were significantly higher in females than males. There was a significant correlation between NMP-Q and TAS-20 scores and MCQ-C scores. TAS-20, MCQ-C scores and gender significantly predicted the nomophobia when NMP-Q score was a dependent variable. Therapeutic interventions for improving social skills like emphatic thinking and/or increasing emotional expression may be beneficial in the treatment of adolescents with alexithymic traits which experience nomophobia. Moreover, interventions that enhance metacognitive skills which can control negative thoughts triggered by the possibility of losing contact with MPs may increase treatment success.

Chest pain in adolescents is rarely associated with cardiac disease. Adolescents with medically unexplained chest pain usually have high levels of anxiety and depression. Psychological stress may trigger non-cardiac chest pain. This study evaluated risk factors that particularly characterise adolescence, such as major stressful events, in a clinical population. The present study was conducted on 100 adolescents with non-cardiac chest pain and 76 control subjects. Stressful life events were assessed by interviewing patients using a 36-item checklist, along with the Children's Depression Inventory and Spielberger's State-Trait Anxiety Inventory for children, in both groups. Certain stressful life events, suicidal thoughts, depression, and anxiety were more commonly observed in adolescents with non-cardiac chest pain compared with the control group. Moreover, binary logistic regression analysis showed that trouble with bullies, school-related problems, and depression may trigger non-cardiac chest pain in adolescents. Non-cardiac chest pain on the surface may point to the underlying psychosocial health problems such as depression, suicidal ideas, or important life events such as academic difficulties or trouble with bullies. The need for a psychosocial evaluation that includes assessment of negative life events and a better management have been discussed in light of the results.

Polymorphism in exon 7 of the endothelial nitric oxide synthase gene G894T seems to be a possible risk factor for intracranial aneurysm rupture.

The association of anxiety, depression, prenatal stressful events and poor family functioning in mothers who have children with BHS is significantly higher than controls. An evaluation of these problems may be beneficial in the management of BHS.
