The effect of long-term use of methylphenidate on cardiac autonomic functions and ventricular arrhythmogenesis: a prospective case-control study.

OBJECTIVE: We aimed to assess cardiac autonomic balance with heart rate variability by using 24-hour Holter electrocardiography and also to assess susceptibility to ventricular arrhythmias by using microvolt T wave alternance in children with attention deficit hyperactivity disorder. METHOD: This study was conducted with age- and gender-matched groups of 40 patients taking long-acting methylphenidate for more than a year and 55 healthy controls. Heart rate variability analysis for cardiac autonomic functions and microvolt T wave alternance measurements for susceptibility to ventricular arrhythmias were evaluated by 24-hour Holter electrocardiography. RESULTS: The mean age 10.9 ± 2.7 years, mean duration of therapy 22.76 months, and mean methylphenidate doses were 37.64 mg/day. The study group had considerably higher rMSSD, higher HF, and a lower LF/HF ratio (respectively, p : 0.02, p : 0.001 and p : 0.01). While parasympathetic activity parameters were elevated, sympathetic activity parameters were low during the sleep period. Increase in the microvolt T wave alternance values of the study group was not found to be statistically significant (p > 0.05). CONCLUSION: In children taking long-acting methylphenidate, the autonomic balance was shown to be in favour of the parasympathetic system. Determination of the vulnerability to life-threatening ventricular arrhythmias has been evaluated for the first time in children with attention deficit hyperactivity disorder. Accordingly, microvolt T-wave alternance values give the notion that drug use is safe.

The Effects of Methylphenidate on Ventricular Repolarization Parameters in Children with Attention-Deficit Hyperactivity Disorder.

Background: Long-acting methylphenidate (MPH), a psychostimulant agent, is widely used in the treatment of attention-deficit hyperactivity disorder (ADHD). Methylphenidate might cause an increment in the risk of lethal arrhythmias by deteriorating ventricular repolarization. QT intervals, the corrected QT (QTc), QT dispersion, T-peak to T-end (TpTe), and the TpTe/QTc ratio are the most utilized indicators of ventricular repolarization in electrocardiogram (ECG). The present study was conducted to examine the effects of long-term MPH use on the ECG in pediatric patients. Methods: A total of 52 children with ADHD and 51 age- and gender-matched controls were enrolled in the study. The children had been using MPH regularly for at least 6 months. Comparisons were made regarding ECG parameters, including the mean intervals of QT, QTc, QTc dispersion interval duration, TpTe intervals, TpTe/QT, and TpTe/QTc ratio. Results: The median duration of treatment with MPH was 30 months (minimum-maximum: 6-120), and the median MPH dose was 30 mg/day (minimum-maximum: 18-54). The main findings showed significantly prolonged P-wave dispersion, TpTe interval, TpTe dispersion, and TpTe/QT and TpTe/QTc ratios in the ADHD group compared to the healthy controls (P < .001). These parameters were not associated with MPH dose or treatment duration. Additionally, nearly half of the patients had QTc values of 460 ms or higher, but there were no significant differences in treatment duration and dose compared to the remaining group (P = .792 and P = .126). Conclusion: Methylphenidate may have proarrhythmogenic effects in children with ADHD, which may not be adversely affected by long-term use and treatment dose. Considering the extensive use of MPH, cardiac monitoring of these children is important.

Higher Levels of Galectin-1 and Galectin-3 in Young Subjects with Autism Spectrum Disorder Compared to Unaffected Siblings and Healthy Controls.

Objective: : Despite being highly genetic, the etiology of autism spectrum disorder (ASD), has not yet been clarified. Recent research has focused on the role of neuroinflammation and immune system dysfunction in the pathophysiology of neurodevelopmental disorders including ASD. Galectin-1 and galactin-3 are considered among the biomarkers of neuroinflammation and there has been recent reports on the potential role of galectins in the etiology of neurodevelopmental disorders. However, there has been no study examining the relationship between ASD and galectin levels. Methods: : Current study aimed to investigate galectin-1 and galectin-3 serum levels in young subjects with ASD comparing with their unaffected siblings and healthy controls. Results: : We found significantly higher levels of galectin-1 in case group compared to both unaffected siblings and healthy controls, and higher levels of galectin-3 in case group compared to healthy controls. However, there was no significant association between galectin-1 and galectin-3 levels with the severity of ASD. Conclusion: : Findings of our study may support neuroinflammation hypothesis in the etiology of ASD and the potential role of galectin-1 and galectin-3 as biomarkers.

Elevated Serum Galectin-1 and Galectin-3 Levels in Children With Specific Learning Disorder: A Case Control Study.

OBJECTIVE: Specific learning disorder (SLD) is a neurodevelopmental disorder in which underlying pathogenesis and etiological factors are not fully understood. Neuroinflammatory response (measured with serum levels of galectin-1 and galectin-3), which is associated with learning and memory, may play an important role in the etiopathogenesis of SLD. Aim of the present study is to examine whether serum galectin-1 and galectin-3 levels are related to SLD. METHODS: The current study consisted of 42 treatment-naive children with SLD and 42 control subjects. All of the subjects were assessed using semi-structured psychiatric examination to diagnose SLD and exclude attention-deficit hyperactivity disorder. Serum galectin-1 and galectin-3 levels were measured via venous blood samples. RESULTS: The SLD and control group did not differ significantly in terms of age, sex, and body mass index (BMI). The SLD group had significantly higher serum levels of galectin-1 (8.78±2.97 vs. 7.40±2.03, p=0.019) and galectin-3 (1.86±0.93 vs. 1.32±0.69, p=0.003) than the control group when controlled for age, sex, and BMI. CONCLUSION: Higher serum levels of galectin-1 and galectin-3 in children with SLD may indicate the role of neuroinflammatory response in the pathogenesis of SLD. Other mechanisms involving galectin-1 and galectin-3 related to learning may play a part in the etiology of SLD.

The Effects of 6q26-q27 Terminal Deletion on Intellectual Disability & Brain Malformations and the Genotype/Phenotype Relationship: A Case Report.

Terminal microdeletion of chromosome 6q is a rare syndrome that can result in a spectrum of phenotypes varying from normal intelligence-minimal clinical symptoms to severe neurological defects and developmental delays. The most frequent clinical characteristics include developmental delays prior to and following birth as well as intellectual disability, brain malformations, and facial dysmorphism. These clinical characteristics may not be correlated with the size of the deletion; as many cases have been identified with either minor or major deletions, the genotype-phenotype correlation should be better investigated. To our knowledge, this is the first report of 6q26-q27 chromosome microdeletion in Turkey. In this article, we determine the clinical and genomic characteristics of a 2-year-old female case of 6q26-q27 chromosome microdeletion by investigating the level of development of the patient, brain malformations and dysmorphic characteristics, and ultimately comparing them to other cases reported in literature. Our patient was diagnosed with severe Global Developmental Delays (GDD). Although our case had similar clinical characteristics to corresponding cases in literature, there is a difference in the variety and group of symptoms exhibited.

A Case of Priapism in a Child With Autism Spectrum Disorder, Possibly Due to Risperidone Treatment With Addition of Atomoxetine.

OBJECTIVES: Risperidone is an effective drug used for the treatment of irritability in children with autism spectrum disorder (ASD). Atomoxetine (ATX) is a well-tolerated drug used in first-line therapy in children with attention-deficit/hyperactivity disorder (ADHD). However, uncommon adverse effects of risperidone and ATX are a concern among mental health professionals. To our knowledge, this is the first case report of priapism after addition of ATX upon existing treatment with risperidone. METHODS: Written informed consent for publication was obtained from the patient and his parents, and their identities were concealed for ethical reasons. RESULTS: Here, we report a case of priapism as an adverse effect of ATX and risperidone treatment in a 7-year-old boy with ASD and comorbid ADHD. In this case, priapism was not observed with risperidone until ATX was added. CONCLUSIONS: Priapism is a condition viewed as a medical emergency. Although risperidone-induced priapism is a rare phenomenon, it is advised for clinicians to consider the drug interactions in treatment of ASD and ADHD in terms of early diagnosis and intervention.

Methylphenidate-Induced Menorrhagia in Twin Girls.

Objective: Methylphenidate, a psychostimulant agent, is used in first-line psychopharmacological treatment in children and adolescents with attention-deficit/hyperactivity disorder. Common side effects associated with methylphenidate use in children and adolescents are insomnia, anorexia, headache, and nausea. Thrombocytopenia, nasal bleeding and menstrual bleeding disorders are very rarely reported during methylphenidate use. One of the least expected side effects during methylphenidate usage is menorrhagia. Method : In this article, we report methylphenidate monotherapy-induced menorrhagia in two adolescent identical twins. To our knowledge, this is the first report of menorrhagia associated with methylphenidate use in children and adolescents. Results: In both cases, menorrhagia has started after methylphenidate monotherapy and stopped after discontinuation. Other possible etiologies have excluded with clinical and laboratory evaluations. Naranjo Adverse Drug Reaction Probability Score was found 7, indicates probable side effect. Conclusion: Menorrhagia is a rare adverse effect of methylphenidate use and clinicians should be aware of this phenomenon.

Motor functions, quality of life and maternal anxiety and depression in children with cerebral palsy of different intelligence levels.

BACKGROUND: Cerebral palsy (CP) is the most common motor disability in childhood. In addition to motor impairment, it is frequently accompanied by intellectual disability (ID). We aimed to investigate the associations between motor functions, quality of life (QoL) and maternal psychopathology in children with CP of different intelligence levels. METHODS: In total, 37 children and adolescents (16 females and 21 males) between 4 and 18 years of age diagnosed with CP were recruited from a Pediatric Neurology Outpatient Clinic. Gross Motor Function Classification System (GMFCS) and Bimanual Fine Motor Function (BFMF) were used for the children`s motor functions assessment. Quality of life was determined by the caregivers with Pediatric Quality Of Life Inventory-Parent version (PedsQL-P). Maternal anxiety and depression levels were assessed using Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). RESULTS: Moderate-severe ID (n=19)(13.5%, 37.8%) and normal IQ-mild ID (n=18) (32.4 %,16.2%) groups were evaluated in this study. GMFCS level 2 was more frequent in both groups. The majority of the severe-moderate ID group was at BFMF level 4, while the normal IQ-mild ID group was at BFMF level 2. PedsQL-P scores of children with CP, maternal BAI scores, and maternal BDI scores did not differ between the two groups (p > 0.05). Psychosocial PedsQL scores had a moderate negative correlation with the maternal BAI scores (r=- 0.41, p < 0.05). There was also a moderate positive correlations between the ages of children and maternal BDI scores (r=0.34, p < 0.05). CONCLUSIONS: Our results demonstrated that maternal anxiety was correlated with psychosocial QoL in children with CP. Maternal depression scores increasing with the ages of the children with CP may also indicate the social support needs for mothers with children of chronic diseases. Further studies may reveal the associations with other biopsychosocial factors in children with CP of different intelligence levels by using longitudinal study designs with larger sample sizes.

Low-Dose Aripiprazole-Induced Nocturnal Enuresis in a 9-Year-Old Boy: A Case Report and the Possible Underlying Mechanism.

ABSTRACT: Aripiprazole is an atypical antipsychotic commonly used in the treatment of psychiatric disorders, such as schizophrenia, bipolar disorder, and irritability associated with autism spectrum disorder. Common adverse effects associated with aripiprazole usage in children and adolescents are nausea, vomiting, extrapyramidal adverse effects, akathisia, sedation, tremor, and increased appetite. Enuresis is one of the least expected adverse effects during aripiprazole use. The pathophysiology of aripiprazole-induced enuresis has not been fully clarified. To our knowledge, our report presents enuresis related to aripiprazole use at the lowest dose in the literature. In this report, we present the case of a 9-year-old boy who developed nocturnal enuresis after the beginning of low-dose aripiprazole treatment.

Parental psychological distress associated with COVID-19 outbreak: A large-scale multicenter survey from Turkey.

AIMS: Pandemics can cause substantial psychological distress; however, we do not know the impact of the COVID-19 related lockdown and mental health burden on the parents of school age children. We aimed to comparatively examine the COVID-19 related the stress and psychological burden of the parents with different occupational, locational, and mental health status related backgrounds. METHODS: A large-scale multicenter online survey was completed by the parents (n = 3,278) of children aged 6 to 18 years, parents with different occupational (health care workers-HCW [18.2%] vs. others), geographical (Istanbul [38.2%] vs. others), and psychiatric (child with a mental disorder [37.8%]) backgrounds. RESULTS: Multivariable logistic regression analysis showed that being a HCW parent (odds ratio 1.79, p < .001), a mother (odds ratio 1.67, p < .001), and a younger parent (odds ratio 0.98, p = .012); living with an adult with a chronic physical illness (odds ratio 1.38, p < .001), having an acquaintance diagnosed with COVID-19 (odds ratio 1.22, p = .043), positive psychiatric history (odds ratio 1.29, p < .001), and living with a child with moderate or high emotional distress (odds ratio 1.29, p < .001; vs. odds ratio 2.61, p < .001) were independently associated with significant parental distress. CONCLUSIONS: Parents report significant psychological distress associated with COVID-19 pandemic and further research is needed to investigate its wider impact including on the whole family unit.

Fluoxetine-induced Systemic Hypertension in a 12-Year-Old Girl: A Case Report.

ABSTRACT: Fluoxetine, a selective serotonin reuptake inhibitor, is an efficacious medication in social anxiety disorder with a generally well-tolerated adverse effect profile. However, infrequent side effects may occur during treatment. Here, we report a case of systemic hypertension in a 12-year-old female patient with social anxiety disorder receiving fluoxetine treatment. To the best of our knowledge, this is the first report of fluoxetine-induced systemic hypertension in children and adolescences.

Caring for the Most Vulnerable: A Model for Managing Maladaptive Behavior in Children with Mental Special Needs During the COVID-19 Pandemic.

Background: This article presents the results of a comprehensive national model developed for managing maladaptive behaviors (MBs) in children with mental special needs (CMSNs) during the coronavirus disease 2019 (COVID-19) pandemic that combines telehealth-based Applied Behavioral Analyses, psychiatric interventions, and support from local psychosocial teams. This study aims to determine the effectiveness of a system that combined telehealth applications with local psychosocial support teams, allowing services from video calls to emergency interventions. Materials and Methods: The system combines the telehealth applications with the services from local psychosocial intervention teams. In addition to system records covering sociodemographic variables and initial complaints, a telephone survey questioning the effectiveness and satisfaction of the system was used as the main outcome. Results: In total, 347 individuals used the system with mothers constituting the majority of applicants (88.7%, n = 332). The overall satisfaction of the system was 8.8/10. In terms of effectiveness, 63.3% (n = 237) of caregivers reported an improvement in the reason of application. Counselors decided on a need for follow-up visits for 36.6% (n = 137) of applications. A referral to a psychiatrist was asked for 40 patients (10.6%). Discussion: To our best knowledge, this is the first study presenting a model for managing MBs of CMSNs during the COVID-19 outbreak. In general, therefore, it seems that there is a need for unique systems to handle behavioral problems of CMSNs. Conclusions: The findings of this study suggest that it is possible to establish an integrative multistep multidisciplinary telehealth-based approach in a short while.

Exacerbation of obsessive compulsive disorder symptoms in children and adolescents during COVID-19 pandemic.

OBJECTIVE: To investigate the effects of COVID-19 pandemic and related home confinement on symptom profile, symptom severity and exacerbation of obsessive compulsive disorder (OCD) symptoms and related factors among young subjects with OCD. METHOD: Young subjects who have been followed up with a primary diagnosis of OCD in a university hospital were reached by telephone or online programs to assess symptom profile, symptom severity and exacerbation during pandemic. Children's Yale-Brown Obsessive Compulsive (CY-BOCS) and Clinical Global Impression- Severity (CGI-S) Scales were used to rate symptom profile and severity before pandemic and during pandemic periods. RESULTS: There was a significant increase in the frequency of contamination obsessions (p=0.008) and cleaning/washing compulsions (p=0.039) during pandemic period. CY-BOCS obsessions (p<0.001), compulsions subscales (p<0.001) and total scores (p<0.001), and CGI-S scores (p<0.001) during pandemic period were statistically higher than before pandemic period. There was a significant relationship between the change in CY-BOCS scores with talking/searching in the social environment about COVID-19, daily preoccupation about COVID-19, duration of OCD diagnosis and diagnosis of COVID-19 in someone familiar. CONCLUSIONS: Young subjects with OCD may develop additional symptoms and worsen already existing symptoms of OCD during COVID-19 pandemic.
