RESUMEN

OBJECTIVE: Specific learning disorder (SLD) is a neurodevelopmental disorder frequently seen in childhood with deficits in many areas of functioning. Although the etiology of SLD is known to be multifactorial, research findings are limited. In this study, we aimed to compare the serum levels of brain-derived neurotrophic factor (BDNF) in children with SLD to healthy children to find out whether BDNF has a role in the pathophysiology of SLD. METHOD: The study included 30 children between the ages of 7-12, diagnosed with SLD and 30 age and gender matched healthy controls. The groups were tested on the Affective Disorders and Schizophrenia Interview Schedule for School-age Children-Now and Lifetime Form (K-SADS-PL), the Wechsler Intelligence Scale for Children-revised form (WISC-R), the Teacher Information Form (TIF) and the Specific Learning Difficulty Battery (SLDB). RESULTS: No difference the serum BDNF levels in children with SLD and the healthy controls. BDNF levels did not correlate with the WISC-R scores and reading rate in the SLD group. CONCLUSION: An association was not determined between SLD and and serum BDNF levels. Our study was the first to investigate this relationship and provided preliminary data on this topic. There is a need for further studies with large patient groups of phenotypic homogeneity.

RESUMEN

BACKGROUND: The aim of this study was to assess the quality of life (QoL) of mothers of children with Down syndrome (DS) and the factors related to it. METHODS: Seventy-five DS child-mother diads and 54 healthy child-mother diads were included in this study. The brief World Health Organization Quality of Life scale - Turkish version (WHOQOL-BREF-TR), Symptom Check List-90-Revised (SCL-90-TR), Beck Depression Inventory, Beck Anxiety Inventory and Maslach Burnout Inventory (MBI) were completed by mothers to assess maternal QoL, burnout, anxiety, depression and general psychiatric symptoms. RESULTS: Mothers of DS children had significantly higher SCL-90 general symptom index scores, Beck depressive symptom scores and higher scores in all domains of the brief World Health Organization Quality of Life scale - (WHOQOL-BREF-TR) except the WHOQOL-BREF-TR-psychological health domain. MBI personal achievement scores were weakly correlated with psychological health in mothers of DS children. There was a reverse correlation between comorbid disorders and the WHOQOL-BREF-TR psychological health domain, and a weak correlation between sex (having a baby girl with DS) and increased WHOQOL-BREF-TR physical health domain score. Number of offspring was negatively correlated with maternal social quality of life. CONCLUSION: Mothers of children with DS are negatively affected in terms of QoL and mental health, even in the early period. It would be useful to systematically screen these mothers and to refer them for appropriate intervention at an early stage.

Senses-Dinç G, Özçelik U, Çak T, Dogru-Ersöz D, Çöp E, Yalçin E, Çengel-Kültür E, Pekcan S, Kiper N, Ünal F. Psychiatric morbidity and quality of life in children and adolescents with cystic fibrosis. Turk J Pediatr 2018; 60: 32-40. The aim of this study was to investigate psychiatric disorders, depression and anxiety levels, and quality of life in children and adolescents with cystic fibrosis (CF), and to compare them with those of children with non-cystic fibrosis (non-CF) bronchiectasis and healthy controls. A total of 103 children and adolescents aged 7-16 years (35 CF, 28 non-CF bronchiectasis, 40 healthy) were evaluated using The Schedule for Affective Disorders and Schizophrenia for School Aged Children (K-SADS), The Child Depression Inventory (CDI), The State-Trait Anxiety Inventories for Children (STAI-C) and the Pediatric Quality of Life Inventory (PedsQL)-C. The three groups were not statistically different with respect to age, sex, and familial sociodemographic variables. 80% of the children and adolescents in the CF group were diagnosed with a psychiatric disorder, which was significantly more compared to those of the two other groups. The CF group had significantly greater rates of depressive and oppositional defiant disorder and the non-bronchiectasis group had a significantly greater rate of anxiety disorder than the control group. The depression and anxiety symptom levels were significantly greater and the quality of life levels significantly lower in both the CF and non-CF bronchiectasis groups than the healthy controls. In the CF group, the presence of any associated psychiatric disorder led to significantly lower total and psychosocial quality of life scores. In conclusion, CF is associated with poorer QOL in childhood. In order to improve quality of life in CF, the psychiatric conditions of children and adolescents should also be evaluated and their follow-up and treatment should involve a multidisciplinary team approach.

RESUMEN

OBJECTIVE: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common psychiatric disorders in adolescence, however, the etiology has not been described. Neuropeptide Y (NPY) is one potential factor that may be involved in the etiology of ADHD. The goal of this study was to evaluate NPY levels in children with ADHD and compare the findings to healthy controls. METHODS: Forty-eight ADHD patients and 40 healthy controls were included in this study. The age range of ADHD patients was 6 to 16 years. All patients were diagnosed according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). RESULTS: The NPY levels of children with ADHD were compared to healthy controls but were not significantly different (t (86)= -0.887,  p= 0.378). NPY levels were similar (F= 0.191, p= 0.826) between ADHD presentations, and included 8 children with predominantly hyperactive-impulsive type (14.3%), 14 children with predominantly inattentive type (30.4%), and 26 children with a combined type (55.4%). There was also no difference between ADHD patients using medical treatment, ADHD patients not using medical treatment, and control subjects in terms of NPY levels (F= 0.572, p= 0.566). There was a significant positive correlation between age and NPY levels in the ADHD group (r= 0.349, p= 0.015). CONCLUSION: This study demonstrated that the NPY levels of ADHD subjects were not different than those of controls. Future studies with homogeneous phenotypes and a larger sample population are needed.

RESUMEN

OBJECTIVE: We aimed to study characteristics of child and mother reported parenting styles of children with Attention Deficit Hyperacitivity Disorder (ADHD) and association of parenting styles of mothers with demographic and clinical variables like ADHD symptoms, sex, age, ADHD subtype, and comorbidity. METHOD: 58 children with ADHD and 30 healthy children were included in this study. All children were assessed by The Schedule for Affective Disorders and Schizophrenia for School Aged Children- Present and Lifetime Version. ADHD symptom severity was assessed by The Conners Parent Rating Scale and The Conners Teacher Rating Scale. The Parenting Style Inventory (PSI) and The Parental Attitude Research Instrument (PARI) were used to assess parenting styles of mothers. RESULTS: ADHD group had lower scores on two subscales of PSI (acceptance/involvement and strictness/supervision) and democratic attitude and equality subscale of PARI and higher scores on strict discipline subscale of PARI compared to control group. In ADHD group, higher symptoms of oppositional defiant disorder were associated with higher mother's strict discipline scores and lower child reported mother's acceptance/involvement scores. CONCLUSION: Our findings supported the idea that there may be an association between parenting attitudes and ADHD symptoms in families having a child with ADHD. These results indicated the importance of integrated approach to ADHD diagnosis and treatment and evaluating the child with ADHD in the context of family environment.

RESUMEN

BACKGROUND: The aim of this study was to assess maternal psychiatric symptoms, family functioning and parenting styles in children with encopresis. METHODS: Forty-one children with encopresis were compared to 29 children without any psychiatric disorder. RESULTS: Higher maternal psychiatric symptoms were found in children with encopresis. The general family functioning and strictness/supervision in parenting were significant predictors of encopresis. CONCLUSIONS: Family functioning may be screened in children with encopresis, especially when standard interventions have had limited success. Identification and treatment of familial factors may enhance the treatment efficacy in encopresis.

RESUMEN

Attention deficit/hyperactivity disorder (ADHD) is the most frequently occurring neuropsychiatric disorder in childhood with an etiology that is not fully understood. A number of reviews that have addressed the neurobiology of ADHD have focused on imaging and genetics. Relatively little attention has been given to factors/mechanisms involved in the brain dysfunction. We suggest that changes in cellular immunity may be involved. Neopterin is a good indicator of cellular immunity, and we evaluated serum levels of neopterin in patients with ADHD. The study group consisted of 49 patients with ADHD. An age- and gender-matched control group was composed of 31 healthy subjects. Venous blood samples were collected, and the levels of neopterin were measured. The levels of neopterin were significantly higher in ADHD than in the comparison subjects. Cellular immunity may have a role in the etiopathogenesis of ADHD.

RESUMEN

Attention deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed neurobehavioral disorder of childhood. The etiopathogeny of ADHD has not been totally defined. Recent reports have suggested a pathophysiological role of neurotrophins in ADHD. In this study, we evaluated serum levels of nerve growth factor (NGF) in patients with ADHD. The sample population consisted of 44 child or adolescent patients diagnosed with ADHD according to DSM-IV criteria; 36 healthy subjects were included in the study as controls. Venous blood samples were collected, and NGF levels were measured. The mean serum NGF levels of the ADHD patients were significantly higher than those of the controls. Age and gender of the patients were not correlated with serum NGF levels. There were no significant differences in NGF levels among the combined and predominantly inattentive subtypes of ADHD. Our study suggests that there are higher levels of serum NGF in drug naive ADHD patients, and that increased levels of NGF might have an important role in the pathophysiology of ADHD.

RESUMEN

BACKGROUND: Anxiety disorders are common in children and adolescents, and they can significantly impair quality of life. Genetic, neurobiological, neurochemical, and psychological factors are believed to play a role in the etiopathogenesis of anxiety disorders. Recent evidence suggests that the pathophysiology of anxiety disorders may be associated with oxidative stress. In this study, we investigated whether there are associations between children with anxiety disorders and total oxidant/antioxidant status. METHODS: The experimental group consisted of 40 patients (children and adolescents) with anxiety disorders. An age- and gender-matched control group composed of 35 healthy subjects was also assessed. Venous blood samples were collected and total antioxidative status (TAS), total oxidative status (TOS), and the oxidative stress index (OSI) were determined. RESULTS: Both the TOS and the OSI of the experimental group were significantly higher than those of the control group. There were no significant differences in TAS between the experimental and control groups. LIMITATIONS: The main limitation of our study was the small sample size. CONCLUSIONS: This study suggests that oxidative balance is impaired in children with anxiety disorders. Oxidative stress may play a role in the etiopathogenesis of anxiety disorders, and TOS may be a useful diagnostic tool in this context.

RESUMEN

Identity and attachment are two concepts of different theories that might be related and that are developmentally very important in adolescence. The aim of this study was to explore the sense of identity, attachment styles and their relation in a group of adolescents with attention deficit hyperactivity disorder (ADHD). Thirty-four adolescents who were diagnosed with ADHD in childhood were reevaluated at the age of 13-16 years. The comparison group consisted of age- and gender-matched adolescents without a psychiatric disorder. The Sense of Identity Assessment Form (SIAF) and the Relationship Scales Questionnaire (RSQ) were used to examine the sense of identity and attachment styles of adolescents, respectively. Compared to adolescents without a psychiatric disorder, adolescents with ADHD, independent of the presence of a comorbid psychiatric disorder, had a similar identity formation process; however, adolescents with ADHD and a comorbid psychiatric disorder experienced more preoccupied attachment styles. Comorbid psychiatric disorders seem to be related to the insecure attachment patterns in adolescents with ADHD.

RESUMEN

This study aimed to compare the quality of life of children and adolescents in various stages of their chronic kidney disease (CKD) who were managed with different treatment modalities to that of children and adolescents without any chronic disease. The study included 18 renal transplant and 21 dialysis patients (8 on hemodialysis, 13 on peritoneal dialysis) and 16 patients who did not yet require renal replacement therapy. The control group consisted of 37 children without any chronic disease. Psychosocial Health Summary scores, Physical Health Summary scores, and Total Scale scores of Pediatric Quality of Life Inventory scores were estimated for the groups. CKD patients had lower scores in all scales of Pediatric Quality of Life Inventory than the control group. There were no differences in self-reported scores on the Pediatric Quality of Life scale scores between treatment groups; however, parents of the transplant patients had reported higher (more favorable) Physical Health Summary scores than those of the dialysis patients. Reports of parents and their children differed only in Physical Health Summary scores in the dialysis group; self-reports of the children were more favorable. These findings show that children and adolescents with CKD experience impaired quality of life on the physical and psychosocial functioning domains in comparison with healthy controls. The study findings implicate the need for further studies to investigate the quality of life in CKD patients at different stages as well as the perceptional differences between pediatric and adolescent CKD patients and caregiver proxy-reports about their quality of life.
