Methods: This study is part of a representative, multi-centered national study that is planned by the Turkish Association of Child and Adolescent Mental Health to evaluate the prevalence of psychopathology among elementary school students in Turkey between the years 2014-2015. Children are screened via Kiddie Schedule for Affective Disorders and Schizophrenia for School Age Children Present and Lifetime Version.

The figure-of-eight walk test is a reliable and valid test for assessing walking skill in people with multiple sclerosis.

Background: The ability to turn while walking is essential for people's activities of daily living. Difficulties in turning while walking are commonly shown in people with multiple sclerosis (PwMS). The figure-of-eight walk test (F8W) is a clinical test assessing walking skill in a curved pathway; however, its reliability and validity have not been systematically examined for PwMS.

The 3-m backward walk test: reliability and validity in ambulant people with multiple sclerosis.

To investigate: (a) the interrater and test-retest reliability of the 3-m backward walk test (3MBW) in ambulant people with multiple sclerosis (PwMS); (b) minimal detectable change (MDC); (c) concurrent and known-groups validity; and (d) the cutoff time to best discriminate fallers from nonfallers with multiple sclerosis (MS). Forty-nine PwMS and 36 healthy people were included in this cross-sectional study. The 3MBW was administered with the timed up and go test, Berg Balance Scale, four square step test, Falls Efficacy Scale-International, and Expanded Disability Status Scale.

Association of cholesterol 7α-hydroxylase (CYP7A1) promoter polymorphism (rs3808607) and cholesterol 24S-hydroxylase (CYP46A1) intron 2 polymorphism (rs754203) with serum lipids, vitamin D levels, and multiple sclerosis risk in the Turkish population.

Background: Patients with multiple sclerosis (MS) have significantly lower vitamin D levels. Cholesterol is known to be the precursor for vitamin D synthesis, and cholesterol removal is regulated by cholesterol 7α-hydroxylase (CYP7A1) in the liver and cholesterol 24S-hydroxylase (CYP46A1) in the brain. In this study, single nucleotide polymorphisms (SNPs) within the genes CYP7A1 (rs3808607) and CYP46A1 (rs754203) were investigated for their effects on serum lipid profiles, vitamin D levels, and the risk of developing MS.

Generation and characterization of human induced pluripotent stem cell line METUi001-A from a 25-year-old male patient with relapsing-remitting multiple sclerosis.

Multiple sclerosis is a chronic disease characterized by inflammation, demyelination, and axonal damage in the central nervous system. Here, we established an induced pluripotent stem cell (iPSC) line METUi001-A from the peripheral blood mononuclear cells of a 25-year-old male individual with clinically diagnosed Relapsing-Remitting Multiple Sclerosis (RRMS) using the integration-free Sendai reprogramming method. We demonstrated that the iPSCs are free of exogenous Sendai reprogramming vectors, have a normal male karyotype, express pluripotency markers, and differentiate into the three germ layers.

Susac Syndrome: Clinical characteristics, diagnostic findings and treatment in 19 cases.

Susac's Syndrome (SS), which was first described in 1979, is a rare and presumably autoimmune disorder characterized by encephalopathy, hearing loss, and visual disturbance resulting from branch retinal artery occlusion (BRAO). This study reports 19 SS patients' clinical characteristics, MRI features, CSF analysis, treatment strategies and outcomes. At initial presentation, only three of 19 patients demonstrated the complete clinical triad.

Association analysis of Glutathione S-transferase omega-1 and omega-2 genetic polymorphisms and ischemic stroke risk in a Turkish population.

Objectives: Oxidative stress is a known risk factor for the pathogenesis of atherosclerosis, the main cause of ischemic stroke. Glutathione S-transferase (GST) omega-1 and omega-2, members of phase II enzymes, play a role in the antioxidant system. The single nucleotide polymorphisms (SNPs), C419A and A424G in GST omega genes can cause a decrease in enzyme activity.

Genetic polymorphisms of vitamin D3 metabolizing CYP24A1 and CYP2R1 enzymes in Turkish patients with ischemic stroke.

Objective Vitamin D deficiency is known as an important risk factor in pathogenesis of atherosclerosis, which contributes to stroke development. Genetic variations including single nucleotide polymorphisms (SNPs) in enzymes involved in vitamin D metabolism can affect susceptibility to the development of stroke. Therefore, the objective of this study was to investigate the association between polymorphisms of vitamin D metabolizing enzymes (rs927650 SNP in CYP24A1, and rs10741657 SNP in CYP2R1 genes,) and ischemic stroke risk in Turkish population.

A Retrospective Study of Long Acting Risperidone Use to Support Treatment Adherence in Youth with Conduct Disorder.

Objective: Risperidone has been widely used to control aggression and conduct disorder (CD) in youth; however, treatment compliance is a major problem in CD. Our aim is to evaluate the effectiveness and tolerability of long-acting risperidone (LAR) in treating nonadherent cases.

Methods: The medical records of children and adolescents who had CD and were nonadherent to conventional drugs and psychosocial interventions (and therefore taking LAR) were reviewed.

Clinical, Radiological and Electrophysiological Comparison of Immunomodulatory Therapies in Multiple Sclerosis.

Introduction: Although it has been shown that immunomodulatory therapies (IMTs) in multiple sclerosis (MS) can modify the course of the disease by reducing the relapse rate and delaying the progression of disability, no study comparing IMTs head-to-head in terms of clinical, radiological, and electrophysiological changes is available. We aimed to investigate the effects of interferon-beta (IFN-B) 1b, IFN-B-1a subcutaneous (sc), IFN-B-1a intramuscular (im), and glatiramer acetate (GA) therapies on clinical, electrophysiological, and radiological findings.

Methods: We studied a cohort of 85 MS patients who were followed up for at least 2 years and had complete charting, including pre-treatment and post-treatment clinical, radiological, and electrophysiological findings.

Association of cytochrome P4502E1 and NAD(P)H:quinone oxidoreductase 1 genetic polymorphisms with susceptibility to large artery atherosclerotic ischemic stroke: a case-control study in the Turkish population.

Stroke, a major cause of death and disability, is described as interruption or severe reduction of blood flow in cerebral arteries. Oxidative stress plays an important role in the pathogenesis of atherosclerosis and carotid atherosclerosis is a risk factor for stroke. Combination of multiple environmental and genetic risk factors is thought to increase stroke.

Vitamin D Deficiency and a Blunted Parathyroid Hormone Response in Children with Attention-Deficit/Hyperactivity Disorder.

Background: Attention-deficit/hyperactivity disorder (ADHD) is the most frequently diagnosed neuropsychiatric disorder of childhood. The etiopathogenesis of ADHD has not been fully defined. Recent evidence has suggested a pathophysiological role of vitamin D deficiency in ADHD.

Decreased cerebral vasomotor reactivity in patients with obstructive sleep apnea syndrome.

Objective: In obstructive sleep apnea syndrome (OSAS), any of the activated neural, vascular, hemodynamic, metabolic, inflammatory, and thrombotic mechanisms may be related to increased cerebrovascular disease and risk of death; however, the possible pathophysiological process between obstructive sleep apnea syndrome and stroke has not been clearly explained. We hypothesize that alterations in vasomotor reactivity in patients may be responsible for their altered cerebral blood flow, and may contribute to the increased risk of ischemic stroke.

Methods: A total of 30 untreated patients with severe obstructive sleep apnea and 26 control subjects were included in the study.

Ziprasidone Augmentation in an Adolescent with Obsessive Compulsive Disorder: A Case Report.

Obsessive compulsive disorder (OCD) is characterized by recurrent, unwanted thoughts (obsessions) and/or repetitive behaviors (compulsions). Although selective serotonin reuptake inhibitors are widely used to treat OCD, only half of the patients respond well. Several potentiation strategies including off-label use of antipsychotics (mostly risperidone, quetiapine) have been tried.

Validity and Reliability of the Turkish Version of the Questionnaire for the Assessment of Dysphagia in Multiple Sclerosis.

Introduction: The aim of this study was to investigate the validity and reliability of the Turkish version of the Questionnaire for the Assessment of DYsphagia in MUltiple Sclerosis (DYMUS) that has been developed for evaluating dysphagia in patients with multiple sclerosis.

Methods: This methodological study was conducted in the neurology clinic and outpatient department of a training hospital between March 15 and September 15, 2015. The study included 117 patients aged 18 years and over who had a definite diagnosis of multiple sclerosis, could communicate in Turkish, and volunteered to be included.

Atomoxetine Use in Attention-Deficit/Hyperactivity Disorder and Comorbid Tic Disorder in Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections.

Attention-deficit/hyperactivity disorder (ADHD) is a common comorbid disease in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS), in which tic-like involuntary movements are frequently seen clinical conditions. In contrast to psychostimulants, atomoxetine is considered as having minimal effects on tics. Here we report two cases with ADHD and PANDAS who were treated with atomoxetine for their ADHD and comorbid tics.

Importance of NOS3 genetic polymorphisms in the risk of development of ischemic stroke in the Turkish population.

In the present study, we aimed to investigate the relationship between endothelial nitric oxide synthase 3 (NOS3) G894T, T-786C, and intron 4 variable number of tandem repeat (VNTR) variants, alone or in combination, and the risk of incidence of ischemic stroke in the Turkish population. The genotypes for all polymorphisms were determined by polymerase chain reaction/restriction fragment length polymorphism techniques on 245 ischemic stroke patients and 145 controls. In the case-control analysis, no significant difference was observed between stroke patients and controls with respect to NOS3 G894T, T-786C, and intron 4 VNTR polymorphisms genotype and allele frequency distribution.
