OBJECTIVE The aim of this study was to conduct a pilot study testing whether single-dose, immediate-release dexmethylphenidate (dMPH) can facilitate tic suppression in children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and Tourette's disorder (TD) or chronic tic disorders. The primary hypothesis is that dMPH will improve behaviorally reinforced tic suppression in a st...

Titanium carbide (TiC) nanoparticles are readily deposited onto tin-doped indium oxide (ITO) electrodes in the form of thin porous films. The nanoparticle deposits are electrically highly conducting and electrochemically active. In aqueous media (at pH 7) and at applied potentials positive of 0.3 V vs. SCE partial anodic surface oxidation and formation (at least in part) of novel core-shell TiC...

We studied 16 pairs of monozygotic twins (mean age, 12.8 +/- 1.4 years; age range, 8 to 26 years; sex, 12 male pairs, four female pairs) in whom at least one twin had Gilles de la Tourette's syndrome (TS) to determine the concordance rates for TS and tic disorders and to examine environmental factors accounting for intrapair differences in tic severity. In this cohort, the concordance rate for ...

AIM We aimed to investigate the contribution of the touch imprint cytology (TIC) of core needle biopsies (CNBs) to the diagnosis in spinal lesions. MATERIAL AND METHODS Sixty cases with spinal CNB and TIC were included in the study. Hematoxylin and Eosin (H&E) and May-Grunwald- Giemsa (MGG) stained TIC slides and CNB of each case were blindly reevaluated by two pathologists. TIC and CNB findi...

Core-shell TiO(2)/C and TiC/C nanofibers are fabricated in situ on Ti and Al ion-implanted Ti substrates by a thermochemical reaction in acetone and the growth mechanism is described. Implantation of Al into Ti leads to in situ growth of TiC/C in lieu of TiO(2)/C nanofibers. This is because Al has a higher affinity to oxygen than Ti and Ti reacts preferentially with C to form TiC. The Ti foil s...

The gold-standard measure of tic severity in tic disorders (TD), the Yale Global Tic Severity Scale (YGTSS), is a semistructured clinician-administered interview that can be time consuming and requires highly trained interviewers. Moreover, the YGTSS does not provide information regarding frequency and intensity of specific tics because all motor and all vocal tics are rated as a group. The aim...

OBJECTIVE To evaluate the relationship between group A beta hemolytic streptococcus infection (GABHS) and tic disorders in children. METHODS This is a case-control study that was conducted in Child and Adolescent Psychiatric Clinic, Isfahan, Iran, between May 2008 and February 2009. Thirty-six children (aged 5-15) with tic and 36 children without tic and obsessive-compulsive disorder (OCD) we...

Tic disorders are childhood onset neuropsychiatric disorders characterized by motor and/or vocal tics. Research has demonstrated that children with chronic tics (including Tourette syndrome and Chronic Tic Disorder: TS/CTD) can suppress tics, particularly when an immediate, contingent reward is given for successful tic suppression. As a diagnosis of TS/CTD requires tics to be present for at lea...
