Purpose To describe and compare the temporal-spatial kinematic variables of mandibular movement during deliberate unilateral and habitual mastication in healthy young-adult individuals. Methods The study sample was composed of eight male healthy volunteers aged 19 to 24 years. The kinematic data were obtained using a motion analysis system - Qualisys Track Manager (QTM) ProReflex MCU. Recordi...

Our patient was diagnosed with unilateral familial retinoblastoma at the age of thirteen days. Nineteen months later magnetic resonance (MR) images of the brain showed a suspicious cystic pineal gland. On a follow-up MR scan after another nine months this lesion was diagnosed as pineoblastoma. The tumor was resected and subsequently highdose chemotherapy was given, concluded with autologous ste...

Galvanic vestibular stimulation (GVS) stimulates the vestibular system electrically with low-amplitude direct current through surface electrodes applied to the left and right mastoids. The effects of GVS on unilateral spatial neglect (USN) in poststroke patients were recently reported, but the influence of the current intensity and application duration of GVS on USN has not been sufficiently in...

Introduction Unilateral labyrinthectomy and intra-tympanic gentamycin have been employed in the treatment of Ménière's disease, but the efficacy of these techniques has not been well established. Objective The objective of this study is to measure the time course of recovery from a unilateral labyrinthectomy either after ipsilateral topical treatment with gentamicin to the inner ear or without ...

A complex link exists between vision and unilateral spatial neglect (USN). Firstly, USN is not a perceptual deficit, secondly, USN is not necessarily accompanied by a visual deficit and finally, USN can be observed in non-visual modalities as well as in mental spatial imagery. This apparent supramodality of USN stands in sharp contrast to the fact that neglect signs are often more severe and mo...

Diazepam and other benzodiazepines are sometimes used to alleviate vertigo and dizziness following labyrinthine surgery in humans. While the results of some previous studies have suggested that the administration of diazepam and other CNS depressant drugs following unilateral labyrinthectomy (UL) may impair the vestibular compensation process, the available evidence is unclear. The objective of...

Detailed analyses of reading and nonlexical tasks by three patients with unilateral spatial neglect (USN) secondary to stroke indicate that the USN in each of these patients affects the left side (contralateral to brain damage) of the viewer, with respect to the viewer's head, mid-sagittal plane of the body, or line of sight. In one case, the neglect was further specified as concerning the left...

We report unilateral megalencephaly in a 14-year-old girl with linear sebaceous nevus syndrome. A review of the radiologic findings in this case and in previously reported cases suggests that the seizures and developmental delay in this neurocutaneous syndrome are related to the migration anomaly of unilateral megalencephaly.
