OBJECTIVE To investigate the incidence, anatomical correlates, and clinical features of imitation and utilisation behaviour, which are thought by Lhermitte and coworkers to represent a reliable and frequent index of frontal lobe disease. METHODS 78 patients with hemispheric local lesions were tested in two separate sessions, in which their reactions to a(More)
We report the case of a newborn child with maple syrup urine disease (MSUD), diagnosed at 10 days of life. Diffusion-weighted echoplanar MRI showed marked hyperintensity of the cerebellar white matter, the brainstem, the cerebral peduncles, the thalami, the dorsal limb of the internal capsule and the centrum semiovale, while conventional dual-echo sequence(More)
BACKGROUND Sickle Cell Disease (SCD) is the most common genetic disease worldwide. Neurological events are among the most worrisome clinical complications of SCD and are frequently accompanied by cognitive impairment. Intellectual function in SCD may vary according to genetic and environmental factors. Immigrant children with SCD are increasing at a global(More)
Four patients with amyotrophic lateral sclerosis (ALS) and dementia are reported. Mental symptoms antedated motor signs and were investigated with a neuropsychology battery, which brought out different patterns of cognitive impairment. A case presented with frontal dementia, another with a predominant aphasic, apraxic, amnesic syndrome, while the remainders(More)
The diagnostic and prognostic assessment of newborn infants with hypoxic-ischemic encephalopathy (HIE) comprises, among other tools, diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) maps. To compare the ability of DWI and ADC maps in newborns with HIE to predict the neurodevelopmental outcome at 2 years of age. Thirty-four term(More)
BACKGROUND The toxicity of styrene on the peripheral nervous system is still debated. CASES The paper presents two cases of peripheral sensorimotor neuropathy in styrene-exposed workers. Exposure, evaluated by biological monitoring, ranged between 100 and 150% of the current limits proposed by the American Conference of Governmental Industrial Hygienists(More)
Mucorales-specific T cells were investigated in 28 hematologic patients during the course of their treatment. Three developed proven invasive mucormycosis (IM), 17 had infections of known origin but other than IM, and 8 never had fever during the period of observation. Mucorales-specific T cells could be detected only in patients with IM, both at diagnosis(More)
Sirs: Central pontine myelinolysis (CPM) is a demyelinating disease of the pons rarely involving other areas of the central nervous system. The etiology and the pathogenesis of CPM remain unclear, though aggressive osmolar correction and in particular rapid correction of hyponatremia are the main factors in treating patients at risk. There is no specific(More)
Sirs: Isolated peripheral hypoglossal nerve palsy is rare and it is caused by primary or secondary tumors of the skull base, leptomeningeal metastases, trauma, carotid artery dissection, surgery or aneurysms of the carotid artery, dural arteriovenous fistula, Chiari malformation, otorhinolaryngological and anesthesiological procedures, radiation, infectious(More)
