    Introduction: The main aims of the current study were (i) to explore the overlap between Internet gaming disorder (IGD) and gaming disorder (GD) diagnoses, (ii) to identify clinical characteristics in clinical settings, and (iii) to measure psychometric properties of the Gaming Disorder Scale for Adolescents (GADIS-A). Methods: 222 adolescents who were followed up within a tertiary-care mental health hospital, were included (IGD/GD group [n = 111], clinical comparison group [n = 90], healthy controls [n = 21]). The tools used were the GADIS-A, Internet Gaming Disorder Scale - Short-Form, The Difficulties in Emotion Regulation Scale (DERS-36), Children's Global Assessment Scale, and a semistructured interview for DSM-5 diagnoses. Results: The overlap rate of IGD and GD is 73%. Comorbid ADHD diagnoses were more commonly found in the IGD group compared to the clinical comparison group. Patients who met GD and IGD diagnoses revealed higher scores in DERS-36. Turkish GADIS-A Item-total score correlation coefficients were between 0.627 and 0.860. In the sample, there was a high level of correlation between the number of DSM-5 and ICD-11 diagnostic criteria met and GADIS-A scale scores. The Cronbach's alphas if item deleted ranged between 0.942 and 0.954. In addition, treatment refusal was more frequent in the IGD group than in the clinical comparison group. Conclusion: The GADIS-A had good to excellent psychometric properties in Turkish adolescents. Despite having a stricter diagnostic criterion, GD overlapped with IGD in a clinical population.

    Serum osteocalcin levels in hyperthyroidism before and after antithyroid therapy
    (TOHOKU UNIV MEDICAL PRESS) Barsal, G; Taneli, F; Atay, A; Hekimsoy, Z; Erciyas, F
    Hyperthyroidism is characterized by accelerated bone turnover, caused from direct stimulation of bone cells by increased thyroid hormones. In this study, we aimed to investigate serum osteocalcin levels as a bone formation marker, before antithyroid (propylthiouracil) therapy at hyperthyroid stage and after antithyroid therapy at euthyroid stage of the patients. Twenty four hyperthyroid patients (18 females, 6 males) and 20 (13 females, 7 males) healthy controls were included into this study. Blood and urine samples were taken before medical treatment at hyperthyroid state, and after the antithyroid therapy until the patients reached the euthyroid state. Serum alkaline phosphatase, osteocalcin, calcium, phosphorus, Free T3, Free T4, TSH and urine calcium/creatinine levels were assessed. We found a significant decrease in serum osteocalcin (p=0.006), urinary calcium/creatinine (p=0.004), and serum phosphorus (p=0.038) levels in euthyroid state in comparison to hyperthyroid state. The increases in serum bone formation marker osteocalcin and bone resorption marker urinary calcium/creatinine levels in hyperthyroid state compared to euthyroid state in our study confirmed that hyperthyroid patients have high bone turnover. We conclude that, hyperthyroid patients has high bone turnover of formation and resorption even after attainment of euthyroidism. Osteocalcin and urine calcium/creatinine are sensitive markers in documenting bone remodeling during treatment of hyperthyroidism. (C) 2004 Tohoku University Medical Press.
