Two children presented with acute hepatitis after starting therapy with atomoxetine
(Strattera(R)). In one child, no competing diagnosis could be identified, and
liver injury resolved completely on withdrawal of the medication. In the second
child, the evaluation was suggestive of type 1 autoimmune hepatitis; she subsequently
improved with removal of atomoxetine and concomitant immunosuppressive therapy.
Atomoxetine may cause clinically significant hepatotoxicity either by metabolic
idiosyncrasy or by inducing autoimmune hepatitis.

Objective: The aim of this study was to examine the association between adherence
to immediaterelease methylphenidate (IR MPH) and maternal psychological distress,
parenting style, parent– child relationship, and perceived family support.
Methods: The sample consisted of 307 children with attention-deficit hyperactivity
disorder (ADHD) (271 boys and 36 girls), 6–17 years of age, who had been
treated with IR MPH for the past 6 months. The measures included the Chinese
Health Questionnaire, Parental Bonding Instrument, Family APGAR, and Home Behaviors
of the Social Adjustment Inventory for Children and Adolescents.
Results: Reasons for poor adherence (n = 79; 25.7%) included forgetting medication
(72.7%), the medication having no effect (20.0%), and refusing medication (12.7%).
Increased age and three-times-daily administration were the major predictors
for poor adherence to IR MPH. Poor adherence was associated with increased degree
of maternal psychological distress, indifferent parenting, maternal overprotection/control,
poor family support, decreased interaction with parents, and increased problems
at home.
Conclusions: Findings indicate that multiple daily dosing of MPH increases the
likelihood of poor adherence, particularly in adolescents, and that poor adherence
is associated with impaired maternal/family process. Once-daily administration
of MPH is necessary to improve adherence and to decrease the possible exacerbation
of tense parent–child relationships caused by poor drug adherence.
Concomitant Use of Atomoxetine and OROSR-Methylphenidate in a 10-Year-Old
Child Suffering from
Attention-Deficit/Hperactivity Disorder with Comorbid Bipolar Disorder and Tourette
Syndrome.

Atomoxetine and OROS® methylphenidate were successfully used concomitantly
in a 10- year-old boy suffering from attention-deficit/hyperactivity disorder
(ADHD) with comorbid bipolar disorder and Tourette syndrome (TS). The child
received valproic acid, clonidine, and ziprasidone concurrently. Because possible
side effects of pharmacological treatment for one diagnosis may exacerbate a
comorbid condition, contingent management strategies, when using polypharmacy,
are mandated
Brain Magnetic Resonance Spectroscopy in Sydenham's Chorea and ADHD.

This report presents clinical, laboratory, and neuroimaging findings in a 7-year-old
male with Sydenham's chorea associated with attention-deficit hyperactivity
disorder. Western immunoblotting revealed serum anti-human basal ganglia tissue
antibodies. Magnetic resonance imaging results were normal. Proton magnetic
resonance spectroscopic imaging disclosed increased choline/creatine ratio in
basal ganglia, frontal, and parieto-occipital areas, and decreased N-acetyl
aspartate/creatine ratio in both basal ganglia and frontal areas. Moreover magnetic
resonance spectroscopy revealed a peak between 3.6-4.2 ppm of unclear significance.
The findings of this study are compared with the previous magnetic resonance
spectroscopic studies reported on Sydenham's chorea and attention-deficit hyperactivity
disorder. Magnetic spectroscopic imaging suggests an autoimmune basal ganglia
damage in the pathogenesis of Sydenham's chorea and fronto-striatal impairment
in attention-deficit hyperactivity disorder. In the present case, the previous
history of an attention-deficit hyperactivity disorder suggests that this neurobehavioral
disorder could be a risk factor for Sydenham's chorea in children with rheumatic
fever.
Once-Daily OROSR Methylphenidate Is Safe and Well Tolerated in Adolescents
With Attention-Deficit/Hyperactivity Disorder

This 8-week, open-label extension of a double-blind study reports on safety
data for 171 adolescents with attention-deficit/hyperactivity disorder (ADHD)
who received once-daily OROS® methylphenidate (MPH) (18–72 mg/day).
Headache, anorexia, and insomnia were the most frequently reported treatment-related
adverse events. The incidence of adverse events was not related to dose. OROS
MPH was safe and well tolerated at doses up to 72 mg/day.
