Association of Reactive-Proactive Aggression and Anxiety Sensitivity with Internalizing and Externalizing Symptoms in Children with Attention-Deficit/Hyperactivity Disorder.

This study evaluates the associations among the symptoms of anxiety, depression, and disruptive behavioral disorders (DBD) in the context of their relationships with reactive-proactive aggression and anxiety sensitivity in children with attention-deficit/hyperactivity disorder (ADHD). The sample consisted of 342 treatment-naive children with ADHD. The severity of ADHD and DBD symptoms were assessed via parent- and teacher-rated inventories. Anxiety sensitivity, reactive-proactive aggression and severity of anxiety and depression symptoms of children were evaluated by self-report inventories. According to structural equation modeling, depression and anxiety scores had a relation with the DBD scores through reactive-proactive aggression. Results also showed a negative relation of the total scores of anxiety sensitivity on DBD scores, while conduct disorder scores had a positive relation with anxiety scores. This study suggests that examining the relations of reactive-proactive aggression and anxiety sensitivity with internalizing and externalizing disorders could be useful for understanding the link among these disorders in ADHD.

The Prevalence of Internet Addiction in Turkish Adolescents with Psychiatric Disorders.

INTRODUCTION: The aim of this study is to determine the prevalence of Internet addiction (IA) in adolescents with psychiatric disorders. METHODS: A total of 310 adolescents, aged from 12 to 18, participated in the study. The psychiatric sample group included 162 participants who had applied to the child psychiatry outpatients service. The psychiatric disorders among those in this group were assessed through clinical interviews based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR). The control group was chosen from adolescents of families who had never sought psychiatric help. The demographics of the participants and the features of their Internet usage habits were gathered through a questionnaire prepared by researchers. Young's Internet Addiction Test was used to assess internet addiction. RESULTS: The frequency of IA was found to be significantly higher in the psychiatric sample group than in the control group (24.1% vs. 8.8%, respectively). A total of 23.9% of the subjects had one, and 12.6% had two or more co-morbid psychiatric diagnoses. The frequencies of the diagnostic groups were as follows: attention deficit hyperactivity disorder 55.6%, anxiety disorder 29.0%, mood disorder 21.0%. CONCLUSION: IA was found to be significantly more common among adolescents in the child psychiatry outpatient department than among the adolescents who had no psychiatric history, even after confounding variables had been controlled. Further studies are needed to define IA more precisely and to improve prevention approaches.

Serum and urinary levels of brain-derived neurotrophic factor (BDNF) in enuresis. / Niveles séricos de factor neurotrófico derivado de cerebro en la enuresis.

OBJECTIVES: Enuresis is one of the most frequently seen psycho-social problems in childhood, which causes anxiety and stress in the child, thus affecting his/her self-respect and quality of life. The aim of the study was to determine the role of bladder function or psychologic factors or both as factors causing enuresis. METHODS: This study on pediatric patients with primary enuresis included 30 patients with monosymptomatic nocturnal enuresis (MonoNE), 30 patients with polysymptomatic nocturnal enuresis (PolyNE), and 30 healthy controls, making a total of 90 subjects with an age range of 8-18. In all subjects, the levels of serum and urinary Brain-Derived Neurotrophic Factor (BDNF) were measured, in addition to urinary creatinine levels and calculated as BDNF/Cr ng/mg creatinine (BDNF/ Cr). RESULTS: The serum BDNF results of the PolyNE group (0.949±0.587) were significantly lower than those of the control group (1.158±0.587) (p=0.014). The urinary BDNF results of the PolyNE group (1.107±0.360) were significantly higher than those of both the MonoNE (0.657±0.272) and the control (0.670±0.271) groups (p<0.0001). The BDNF/Cr results of the PolyNE group (1.472±0.714) were significantly higher than those of the MonoNE group (0.956±1.017) and the control group (0.931±0.618) (p=0.044 and p=0.032, respectively). CONCLUSIONS: In addition to bladder-specific problems, it is possible for anxiety and psychological stress-induced problems to occur in PolyNE. Therefore, in addition to the increasing number of studies on the bladder in enuresis, further studies on the neurogenic and psychogenic aspects of enuresis should be carried out.

OBJETIVOS: La enuresis es uno de los problemas psicosociales más frecuentes en la infancia, que causa ansiedad y estrés a los niños, afectando a su autoestima y calidad de vida. El objetivo de este estudio es la determinación del papel de la función vesical, los factores psicológicos o ambos como factores causales de la enuresis.MÉTODOS: Este estudio en pacientes pediátricos con enuresis incluyó 30 pacientes con enuresis nocturna monosintomática (ENmono), 30 pacientes con enuresis nocturna polisintomática (ENpoli) y 30 controles sanos, sumando un total de 90 individuos con un rango de edad entre 8-18 años. En todos los casos se midieron los niveles séricos y urinarios de factor neurotrófico derivado del cerebro (FNDC), además de los niveles de creatinina urinaria y se hizo el cálculo de FNDC/Cr ng/mg creatinina. RESULTADOS: Los resultados de FNDC sérico en el grupo ENpoli (0,949±0,587) fueron significativamente menores que los del grupo control (1,158±0,587) (p=0,014). Los resultados de FNDC urinario en el grupo de ENpoli (1,107±0,360) fueron significativamente mayores que los de los grupos ENmono (0,657±0,272) y control (0,670±0,271) (p<0,0001). Los resultados de FNDC/Cr el grupo ENpoli (1,472±0,714) eran significativamente mayores que los de los grupos ENMono (0,956±1,017) y control (0,931±0,618) (p=0,044 y p=0,032, respectivamente). CONCLUSIONES: Además de problemas específicos vesicales, es posible que los problemas de ansiedad e inducidos por estrés psicológico ocurran en la ENPoli. Por lo tanto, además del creciente número de estudios sobre la vejiga en enuresis, es necesario desarrollar más estudios sobre los aspectos neurogénicos y psicogénicos de la enuresis.

Retinal Nerve Fiber Layer Thickness in Children With ADHD.

OBJECTIVES: The current study aims to compare retinal nerve fiber layer (RNFL) thickness, macular thickness, and macular volume between children with ADHD and a control group. METHOD: The study group included children with ADHD and the control group consisted of age- and gender-matched participants without any psychiatric disorder. In all participants, RNFL thickness, macular thickness, and macular volume were measured by using spectral domain-optical coherence tomography (SD-OCT). ADHD symptom severity was evaluated by using parent-report measures, including Conners' Parent Rating Scale-Revised: Short Form (CPRS-R: S) and the Strengths and Difficulties Questionnaire: Parent Form (SDQ: P). RESULTS: We compared 90 eyes of 45 children with ADHD and 90 eyes of 45 controls. ADHD group had significantly lower RNFL thickness only in nasal quadrant than the controls. The remaining RNFL quadrants, macular thickness, and volume were not significantly different between groups. There was a reverse correlation between RNFL thickness and ADHD symptom severity. CONCLUSION: This is the first study examining the RNFL thickness in ADHD. Our findings showed that nasal RNFL thickness was lower, indicating reduced unmyelinated axons in the retina of children with ADHD. The results of this study support the evidence that ADHD involves a lag in cortical maturation and this is measurable in the retina.

The Relationship Between Parental Affective Temperament Traits and Disruptive Behavior Disorders Symptoms in Children With ADHD.

OBJECTIVE: This study investigated the relationship between parental affective temperaments and the oppositional defiant disorder (ODD) and conduct disorder (CD) symptoms of children with ADHD. METHOD: The sample consisted of 542 treatment-naive children with ADHD and their biological parents. Children were assessed via both parent- and teacher-rated behavioral disorder scales. Parental affective temperament and ADHD symptoms were measured by self-report inventories. The relationships between psychiatric variables were evaluated using structural equation modeling. RESULTS: According to parent-rated behavioral disorder scales, paternal cyclothymic and maternal irritable temperaments were associated with ODD scores, and maternal depressive temperament was associated with CD scores. In terms of teacher-rated behavioral disorder scales, maternal anxious temperament was associated with ODD scores, and paternal cyclothymic and maternal depressive temperaments were associated with CD scores. CONCLUSION: These results suggest that certain parental affective temperaments are related to an increase in symptoms of disruptive behavioral disorders in children with ADHD.

Prevelance of mental disorders and associated factors in institutionalized 3-5 year old children.

OBJECTIVE: In this study, we aimed to determine the prevelance and severity of mental disorders in institutionalized children between the ages of 3-5 years, investigate the factors associated with the mental disorders and compare these findings with the data of a community sample composed of children who were raised by their own families. METHOD: Thirty-four children raised in three institutions in Kocaeli were compared with an age- and sex-matched community sample. Children were assessed according to DSM-IV diagnostic criteria. The Socio-demographic information form, and Early Childhood Inventory-4 (ECI-4) parent scale were used for data collection. RESULTS: Children that were reared in institutions had evidence of higher rates of mental disorders. In institution-reared children, symptom severity of attention deficit hyperactivity disorder, reactive attachment disorder, oppositional deficient disorder, and pervasive developmental disorder were higher than the community subjects. Age, time spent with father, duration of institutionalization, number of siblings, number of hospital admissions because of physical symptoms and presence of abuse before institutional care were determined to be predictive factors for psychiatric symptoms. CONCLUSION: These findings revealed that institutionalized children are at risk for mental disorders and protective measures are as important as instutional care for these children. Our results suggest that essential steps should be taken to protect the mental health of children in institutional care.
