Adolescence is a period of heightened vulnerability both to addictive behaviors and drug-induced brain damage. Yet, only limited information exists on the brain mechanisms underlying these adolescent-specific characteristics. Moreover, distinctions in brain correlates between predisposition to drug use and effects of drugs in adolescents are unclear. Using(More)
PURPOSE It is assumed that preoperative use of a bone-anchored hearing aid (BAHA) test-band will give a patient lower gain compared to real post-operative gain because of the reduction of energy through the scalp when using a test-band. Hearing gains using a BAHA test-band were analyzed in patients with unilateral hearing loss. MATERIALS AND METHODS(More)
In a sample of 235 families with at least two children with Attention-Deficit/ Hyperactivity Disorder (ADHD), the frequency and familial association of learning disabilities (LD) were assessed. Familiality was examined both between sibling pairs and between parents and their children. Two methods for defining LD, a discrepancy-based and a low-achievement(More)
CONCLUSION Our findings suggest that migrainous vertigo (MV) has a substantial vestibulo-spinal abnormality that can be uncovered by posturography. Patients with MV also showed a difficulty in using multisystem information, especially somatosensory information. Caloric and sensory organization tests (SOTs) have complementary roles in assessing(More)
OBJECTIVE We aimed to determine whether abnormalities in outer hair cell (OHC) function were related to tinnitus through interaural comparison of distortion product otoacoustic emissions (DPOAEs). STUDY DESIGN Cross-sectional study. SETTING Tertiary care university teaching hospital. PARTICIPANTS Twenty-seven patients with unilateral tinnitus and(More)
We evaluated the short-term efficacy of Epley, Semont, and sham maneuvers for resolving posterior canal benign paroxysmal positional vertigo (BPPV) in a prospective multicenter randomized double-blind controlled study. Subjects were randomly divided into three groups: Epley (36 patients), Semont (32 patients), and sham (Epley maneuver for the unaffected(More)
BACKGROUND AND PURPOSE The ability of sparse temporal acquisition to minimize the effect of scanner background noise is of utmost importance in auditory fMRI; however, it has considerably lower temporal efficiency and resolution than the conventional continuous acquisition method. The purpose of this study was to determine whether sparse sampling could be(More)
We report a 73-year-old woman with primary left atrial rhabdomyosarcoma and its 1H MR spectroscopy (MRS) findings. The tumor showed a 2.8 cm sized lesion in the posteroinferior atrial wall on MRI. 1H MR spectra were acquired using a point-resolved spectroscopy (PRESS) sequence with electrocardiographic (ECG) gating and respiratory motion. The use of 1H-MRS(More)
