Social media addiction, escapism and coping strategies are associated with the problematic internet use of adolescents in Türkiye: a multi-center study.

Introduction: The literature highlighted that problematic internet use can have detrimental consequences on individuals' well-being. Social media addiction, escapism and coping skills are closely related to problematic internet use. However, no study has currently examined the relationship between problematic internet use and social media use, escapism and coping skills. Method: This multicenter cross-sectional designed study evaluated the relationships between problematic internet use and social media addiction, escapism, and coping skills in 508 adolescents (319 female) aged 14-18 years. In order to collect data, sociodemographic data form, Internet Addiction Scale, Social Media Addiction Scale, Escapism Scale and Kidcope Adolescent Version have been used. First, adolescents who scored ≥50 on the Internet Addiction Test were classified as the problematic internet use group; adolescents who scored <50 were classified as the control group. Then, the relationships between problematic internet use and social media addiction, escapism and coping skills were evaluated. Results: The results showed that problematic internet use was associated with duration of social media use, impairment in social media-related functionality, preferring virtual life, and virtual pleasure, escapism, avoidant and negative coping strategies. Conclusion: These findings may provide an empirical basis for problematic internet use prevention and intervention in adolescence.

Serum claudin-5, claudin-11, occludin, vinculin, paxillin, and beta-catenin levels in preschool children with autism spectrum disorder.

AIM: Increased intestinal and blood-brain barriers (BBB) permeability has been suggested to have a role in autism spectrum disorder (ASD). Claudin-5, claudin-11, occludin, ß-catenin, vinculin, and paxillin are crucial components of these barriers. This study assessed concentrations of these molecules in preschool children with ASD. METHODS: A total of 80 children with ASD and 40 controls aged 18-60 months were enrolled in this study. Serum levels of biochemical variables were determined using commercial enzyme-linked immunosorbent assay kits. RESULTS: Serum claudin-11, occludin, and ß-catenin levels were significantly higher in the ASD group than in the control group. However, no significant difference for serum claudin-5, vinculin, and paxillin levels was detected between the groups. CONCLUSION: These findings suggest that claudin-11, occludin, and ß-catenin may be involved in the pathogenesis of ASD. These proteins may affect the brain by causing dysregulation in intestinal or blood-brain barrier permeability or with other unknown mechanisms.

Oculogyric Crisis Due to Low-Dose Olanzapine: A Case Report.

OBJECTIVES: Oculogyric crisis is a dystonic movement disorder characterized by continuous contraction of the ocular muscles and spasmodic movements of the pupils in a fixed position, usually upward. METHODS: In this case report, an early-stage acute oculogyric crisis due to low-dose olanzapine in a 15-year-old adolescent boy is presented. RESULTS: To the best of our knowledge, this is the first report showing that acute oculogyric crisis can develop with low-dose olanzapine administration. CONCLUSIONS: Even though second-generation antipsychotics are safer than conventional antipsychotics in terms of extrapyramidal adverse effects, this possibility should always be taken into consideration through this case report.

Serum Brain-Derived Neurotrophic Factor, Glial-Derived Neurotrophic Factor, Nerve Growth Factor and Neurotrophin-3 Levels in Preschool Children with Language Disorder.

INTRODUCTION: Accumulating studies demonstrate that neurotrophins may play a crucial role in a variety of neurodevelopmental disorders. However, little data are available regarding the potential role of neurotrophins in language disorder (LD). This study aimed to investigate serum brain-derived neurotrophic factor (BDNF), glial-derived neurotrophic factor (GDNF), nerve growth factor (NGF) and neurotrophin-3 (NTF3) levels in preschool children with LD. METHODS: A total of 43 cases with LD and 43 healthy controls aged 18 to 60 months were enrolled in the study. The development levels and psychiatric symptoms of the children were determined by the Ankara Developmental Screening Inventory and Child Behavior Checklist 1.5-5, respectively. Serum neurotrophin levels were assessed by enzyme-linked immunosorbent assay kits. RESULTS: Serum GDNF and NGF levels were significantly higher, serum BDNF and NTF3 levels were significantly lower in the LD group than in the control group. However, with logistic regression analyses, only negative relationship of BDNF and NTF3 levels with the presence of LD remained significant after accounting for the confounders including development level and coexisting psychiatric symptoms. CONCLUSIONS: These results suggest that low BDNF and NTF3 levels have independent negative relationships with LD, which could be contribute to etiopathogenesis of the disorder.

Excessive Masturbation Successfully Treated With Methylphenidate in a 6-Year-Old Child With Autism Spectrum Disorder Accompanied by Attention Deficit Hyperactivity Disorder.

ABSTRACT: Children with autism spectrum disorder frequently exhibit inappropriate sexual behaviors, such as excessive masturbation. However, research on the control and management of excessive masturbation in these children is very limited. In this presentation, excessive masturbation that responded to treatment with methylphenidate is described in a young boy diagnosed with autism spectrum disorder and comorbid attention deficit hyperactivity disorder.
