Several human imaging studies have described the neural network involved in power grip under visual control and the subset of cortical areas within this network that are sensitive to force modulation. As there is behavioral evidence for late maturation in even simple hand motor tasks involving visual feedback, we aimed at identifying the neural correlates(More)
Abilities to discriminate forms defined by motion continue to develop throughout childhood. To investigate late development of the visual motion system, we measured brain activity with event-related EEG potentials (ERPs) and functional magnetic resonance imaging (fMRI) in groups of adolescents (15-17 years) and adults (20-30 years) during a visual form(More)
OBJECTIVE Magnetic resonance imaging (MRI) has proven its value for noninvasive assessment and classification of atherosclerotic lesions. MRI provides excellent access to soft tissue information, but its capability for assessing calcified segments of the lesion remains limited. The aim of this study was to investigate the ultra-short echo time (UTE)(More)
OBJECTIVE To estimate patient preoperative anxiety, and determine associated factors. METHODS Fifty surgical patients were investigated prospectively at the University Hospital, Rabat, Morocco between January and June 2008. Ethical Committee approval was obtained prior to conducting this study. A short version of the Hamilton scale was used. Descriptive(More)
Hypothyroidism is frequently associated with different neuromuscular disorders. However, myotonia is rarely a revealing feature. We report a case of hypothyroidism secondary to Hashimoto's thyroiditis and myotonia. The patient is a 45-year-old woman who consulted for a progressive myotonia. Blood and thyroid assessments revealed peripheral hypothyroidism(More)
Glioblastomas are the most frequent and aggressive primary brain tumors which are expressing various evolutions, aggressiveness, and prognosis. Thus, the 2007 World Health Organization classification based solely on the histological criteria is no longer sufficient. It should be complemented by molecular analysis for a true histomolecular classification.(More)
Tuberculosis is endemic in developing countries. However, skull tuberculosis is uncommon with few cases reported in the literature. We report a 10-year-old boy admitted for a left parietal painless swelling. A CT scan demonstrated a left parietal bony defect, destroying both inner and outer tables. This was associated with an enhanced epidural collection(More)

D is a movement disorder, which is defined as an “involuntary” sustained muscle contraction affecting one or more sites of the human body. Frequently it originates twisting and respective movements or abnormal postures.1 The dystonic phenomenon occurs during the wake state and increases with fatigue and stress, while it improves with relaxation, hypnosis,(More)
