The aim of this study was to investigate Internet use habits and problematic Internet use (PIU) in Turkish adolescents. Participants were 3,975 undergraduate students, 7.6% of whom used the Internet for more than 12 hours weekly. The Online Cognition Scale (OCS) was used. The most common purpose for using the Internet was playing games, followed by general information search. Female users mostly preferred searching for general information; male users preferred playing games (p < 0.001, gamma = 995.205). The most preferred type of game was violent games. While preference for strategy and fantasy role-play (FRP) games increased with age, preference for other games decreased (p < 0.0001, gamma = 283.767). Participants who used the Internet mostly for general information searches and school-related searches had lower OCS scores (p < 0.0001). The highest OCS scores were related to violent games, followed by FRP, strategy, and sports and motor racing games. Computers and the Internet are useful, important inventions, but like other inventions, if used improperly, they may be harmful. Risk of harm raises concerns about who should use the Internet and computers, and where, when, and why the Internet and computers should be used.

The aim of this study was to evaluate anxiety, depression, alexithymia, and general psychological symptoms in the mothers of autistic children in comparison with those in the mothers of mentally retarded children. Forty mothers of autistic children and 38 mothers of mentally retarded children were included in the study. After a clinical interview, psychometric tests were performed for depression, anxiety, alexithymia, and Symptom Distress Check List (SCL-90) for general psychological symptoms. Non-depression rates was 27.5% in the mothers of autistic children whereas the rate was 55.3% in the mothers of mentally retarded children. There was no difference regarding anxiety and alexithymia between the two groups. The psychopathology in the mothers of autistic children was more frequent than in those of mentally retarded children in all sub-scales of SCL-90 (somatization obsessive-compulsive, interpersonal sensitivity, depression, anxiety, anger-hostility, phobic anxiety, paranoid thought, psychotism, and extra scale). The mothers of autistic children experienced more psychological distress than those of mentally retarded children. Our findings indicates that the assessment of autistic and mentally retarded children should include psychological assessment of their mothers.

While regional cerebral blood flow (rCBF) studies on adults involving the caudate, prefrontal, orbitofrontal, and cingulated areas have been reported, no such published data on children exist. In this study, we aimed to determine the significance of pre- and post-treatment regional cerebral blood flow (rCBF) differences in children with obsessive compulsive disorder (OCD) and compared them with healthy controls. Eighteen drug-free obsessive compulsive children, aged 11 to 15, without comorbid states except for anxiety disorders--participated in this study. The control group consisted of 12 children, aged 11 to 15, with no medical or psychiatric illnesses. Using SPECT (Single Photon Emission Computerized Tomography) scans with Technetium-99m-HMPAO-hexamethly propyleneamine oxime (Tc99mHMPAO), the rCBF was calculated in 15 regions of the control group according to a standard protocol, while in the study group, it was measured at baseline and after 12 weeks of treatment with a fixed dose of paroxetine (20 mg qd). We compared the resulting pre- and post-treatment CBF values for the control group and study group. The right and left caudates, right and left dorsolateral prefrontals, and cingulate had significantly higher rCBF in children with obsessive compulsive disorder than in the control group. These areas, in addition to the right anteromedial temporal, showed significant rCBF reduction after treatment with paroxetine. The mean percentage of change in obsession scores during the treatment correlated significantly with the baseline and post- treatment rCBF level of the right caudate, post-treatment left caudate, and baseline left caudate. Our findings on children are consistent with adult studies and support the theory of a cortical-striatal-thalamic-cortical loop disturbance in OCD.

The purpose of this study was to determine the socio-demographic characteristics of sexually abused children. The records of 101 cases of child sexual abuse (CSA) were retrospectively evaluated. Socio-demographic characteristics of the victims, type of sexual abuse, and psychiatric diagnosis were studied. Of the victims, 56.4% (n = 57) were female and 43.6% (n = 44) were male. The mean age was 9.57 +/- 3.5, with a range of 4-17 years. Ninety-three (92.1%) of the victims had been admitted as part of the legal process. The majority (66.3%) of the victims had been abused by an acquaintance, while 33.7% had been abused by a stranger. Anal or vaginal penetration was reported in 48.5% of the cases. Post-traumatic stress disorder was the most common (54.5%) psychiatric diagnosis established after sexual abuse. Descriptive data related to the abused children and an understanding of the consequences of CSA will help authorities in planning prevention.

We conclude that ADHD + BPD in Turkish children represents a clinical picture different to that of ADHD alone, in which the clinical characteristics resemble those of children reported in the literature. Further long-term follow-up studies are needed in larger clinical and community samples.

This study supports the hypothesis that an association between vitamin D metabolism and PANDAS-related OCD exists. We suggest that biochemical parameters predicting metabolic bone diseases are more common in PANDAS patients. There is a need for prospective studies to show a clear association between PANDAS and bone metabolic turnover based on autoimmune mechanisms.
