Kynurenine, Kynurenic Acid, Quinolinic Acid and Interleukin-6 Levels in the Serum of Patients with Autism Spectrum Disorder.

: It is known that inflammatory processes play a role in the pathogenesis of autism spectrum disorder (ASD). It is also reported that immune activation induces the kynurenine pathway (KP), as known as the tryptophan destruction pathway. In our study, we aimed to investigate whether the serum levels of KP products and interleukin (IL)-6 activating indolamine 2-3 dioxygenase (IDO) enzyme are different in healthy developing children and children with ASD.

The prevalence of childhood psychopathology in Turkey: a cross-sectional multicenter nationwide study (EPICPAT-T).

Aim: The aim of this study was to determine the prevalence of childhood psychopathologies in Turkey.

Method: A nation-wide, randomly selected, representative population of 5830 children (6-13 years-old) enrolled as a 2nd,3rd or 4th grade student in 30 cities were evaluated for presence of a psychiatric or mental disorder by a Sociodemographic Form, Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL), and DSM-IV-Based Screening Scale for Disruptive Behavior Disorders in Children and Adolescents scales. Impairment criterion was assessed via a 3 point-Likert scale by the parent and the teacher independently.

Risperidone Related Raynaud's Phenomenon: An Adolescent Case.

Raynaud's phenomenon is a recurrent vasospastic condition with reducing in peripheral blood flow due to cold, or emotional stress. White, blue and red discolorations occur during the attacks. Serotonin reuptake inhibitors, psychostimulants, and aripiprazole are reported to be related with Raynaud's phenomenon.

Accompanying migrainous features in pediatric migraine patients with restless legs syndrome.

The present study aimed to examine the frequency of restless legs syndrome (RLS) in pediatric patients with migraine and tension-type headache (TTH) and to investigate accompanying migrainous symptoms, sleep characteristics, as well as levels of serum ferritin between the pediatric migraine patients with RLS and those without RLS. We included 65 consecutive patients diagnosed with migraine, 20 patients with TTH, and 97 headache-free children in our study. Demographic, clinical, and laboratory data were noted.

Neuroleptic Malignant Syndrome Associated with Valproate in an Adolescent.

Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction that usually occurs after the administration of antipsychotic drugs. Antidepressants, benzodiazepines, and antiepileptic drugs are also suggested to be associated with NMS. It is believed to result from a dopaminergic blockade in the central nervous system.

Serotonin Syndrome after Clomipramine Overdose in a Child.

Serotonin syndrome (SS) is a potentially life-threatening condition associated with increased serotonergic activity in central nervous system and may occur during the use of serotonergic drugs. Although increasing frequency of serotonergic drug use in children, pediatricians, emergency medicine and pediatric intensive care specialists have not enough knowledge and experience about SS that is a potentially life-threatening condition. A 12-year-old girl patient was admitted to our emergency room with the history of involuntary contractions on her extremities and alteration of consciousness.

Serum IL-4 and IL-10 Levels Correlate with the Symptoms of the Drug-Naive Adolescents with First Episode, Early Onset Schizophrenia.

Objective: In this study, it was aimed to understand the underlying possible immunopathogenesis of first episode, early onset schizophrenia (EOS) through profiling the T helper 1 (Th) cell cytokines TNF-α, IFN-γ, and IL-2, Th cell cytokines IL-4 and IL-10, Th cell cytokine IL-17A, and inflammatory cytokine IL-6.

Methods: The study included a total of 30 children, admitted to child psychiatry outpatient clinic aged between 10 and 17 years of age, who had not received prior therapy and were diagnosed with psychosis according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) as the patient group, and 26 age- and gender-matched children as the control group. Structured psychiatric interviews (K-SADS-PL and PANSS) were conducted with all participants.

Tibia stress fracture secondary to obsessive compulsive disorder.

Obsessive compulsive disorder (OCD) is a chronic psychiatric disorder characterized by obsessions and compulsions. Early-onset OCD is one of the most common mental illnesses of children and adolescents, with a prevalence of 1% to 3%. It is related to worse lifespan symptoms and prognosis.

Persistent hiccups due to aripiprazole in an adolescent with obsessive compulsive disorder responding to dose reduction and rechallenge.

Our case involves persistent hiccup arising in an adolescent with obsessive compulsive disorder (OCD) who was using aripiprazole as an augmentation to fluoxetine and whose hiccups remitted with dose reduction and rechallenge. Treatment suggested that aripiprazole might lead to hiccups. Antipsychotics are also used for the treatment of hiccups, but recent case reports suggest that they cause hiccups as well.

Risperidone Induced Pisa Syndrome in a Male Adolescent.

Pisa syndrome, a rare dystonic reaction resulting from prolonged exposure to antipsychotic medications, is characterized by persistent dystonia of trunk muscles and abnormal posture. It is called Pisa syndrome, because the abnormal posture resembles the Leaning Tower of Pisa. Different from other types of dystonic reactions, Pisa syndrome is more prevalent in females and in older patients with organic brain changes.

Effects of methylphenidate on appetite and growth in children diagnosed with attention deficit and hyperactivity disorder.

The purpose of this study was to determine the levels of leptin, ghrelin, and nesfatin-1 to elucidate the causes of poor appetite and growth retardation in patients receiving methylphenidate therapy for attention deficit hyperactivity disorder. The study was performed on 89 male subjects; 48 patients and 41 healthy controls, aged 7-14 years. Following treatment, patients' leptin levels increased and ghrelin levels decreased while no significant change was found in nesfatin-1 levels.

Dystonia in an adolescent on risperidone following the discontinuation of methylphenidate: a case report.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with common comorbidities that include oppositional defiant disorder, conduct disorder, anxiety disorder, and affective disorders. Because of these comorbidities, drug combination treatments and drug-drug interactions are becoming increasingly more frequent. The present case report describes an acute dystonic reaction following the abrupt discontinuation of methylphenidate from a drug regimen with risperidone.

Atopic disorders are more common in childhood migraine and correlated headache phenotype.

Background: The supportive clinical and pathophysiological data about the correlation between migraine and atopic disorders are far from a coincidence. In order to determine and investigate the correlates of atopic disorders in a specific dataset, we performed this retrospective cross-sectional clinical-based study.

Methods: The dataset was composed from three tertiary center web-based databases (http://www.
