OBJECTIVE To examine in vivo glutamatergic neurochemical alterations in the anterior cingulate cortex of pediatric patients with obsessive-compulsive disorder (OCD) without major depressive disorder (MDD) versus pediatric patients with MDD without OCD and healthy controls. METHOD Single-voxel proton magnetic resonance spectroscopic examinations of the(More)
OBJECTIVE To examine in vivo glutamatergic neurochemical alterations in the anterior cingulate cortex of children with major depressive disorder (MDD). METHOD Single-voxel proton magnetic resonance spectroscopic (H-MRS) examinations of the anterior cingulate cortex were conducted in 13 psychotropic-naïve children and adolescents with MDD and 13 age- and(More)
In this preliminary study, 16 psychotropic-naïve pediatric patients with obsessive-compulsive disorder (OCD) were studied using magnetic resonance spectroscopy (MRS) and genotyped for six candidate polymorphisms in two glutamate system genes. A significant association was identified between the rs1019385 polymorphism of the glutamate receptor, ionotropic,(More)
The pituitary gland plays a central role in sexual development and brain function. Therefore, we examined the effect of age and gender on pituitary volume in a large sample of healthy children and adults. Volumetric magnetic resonance imaging (MRI) was conducted in one hundred and fifty four (77 males and 77 females) healthy participants. Males were between(More)
BACKGROUND Neurobiologic abnormalities in medial thalamus have been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). We previously used multislice proton magnetic resonance spectroscopic imaging (1-H MRSI) to identify localized functional neurochemical marker alterations in choline (Cho) in medial but not lateral thalamus in(More)
BACKGROUND Abnormalities in the amygdala and hippocampus have been implicated in the pathogenesis of major depressive disorder (MDD). To our knowledge, no prior study has examined amygdala-hippocampus anatomy in pediatric patients with familial MDD (at least one first degree relative with MDD). METHODS Thirty-two psychotropic-naive patients with familial(More)
OBJECTIVE The authors investigated structural abnormalities in brain regions comprising cortical-striatal-thalamic-cortical loops in pediatric patients with obsessive-compulsive disorder (OCD). METHOD Volumes of the caudate nucleus, putamen, and globus pallidus and gray and white matter volumes of the anterior cingulate gyrus and superior frontal gyrus(More)
BACKGROUND Anterior cingulate cortex has been implicated in the pathogenesis of major depressive disorder (MDD). With single voxel proton magnetic resonance spectroscopy, we reported reductions in anterior cingulate glutamatergic concentrations (grouped value of glutamate and glutamine) in 14 pediatric MDD patients versus 14 case-matched healthy control(More)
BACKGROUND AND PURPOSE Percutaneous vertebroplasty in the upper cervical spine is a challenging procedure, and little is known about its therapeutic outcome. The purpose of this study was to assess the risks and benefits of percutaneous vertebroplasty for metastatic involvement of the axis. METHODS From January 1994 to August 2004, 12 patients (mean age,(More)
Direct arteriovenous fistulae supplied by the external carotid artery are unusual. Rarely, congenital fistulae have been described involving the head and neck. We describe the first case of congenital internal maxillary arteriovenous fistula in a child. Balloon embolization is currently considered the method of choice for treatment of direct arteriovenous(More)
