To establish reference values for measures of blood flow velocities and impedance indexes in healthy individuals through conventional transcranial Doppler (TCD) and to observe their variations in relation to the age and sex. ⋯ TCD was shown useful in the evaluation of hemodynamic cerebral for our population. Our results are similar to the other studies, so much in the reference values as in relationship with the age and the sex.

A case of isolated velopalatine paralysis in an 8-year-old boy is presented. The symptoms were sudden-onset of nasal speech, regurgitation of liquids into the nose and dysphagia. ⋯ Infectious serologies disclosed an antibody arrangement towards parvovirus B19 that was typical of recent infection. In the absence of other positive data, the possibility of a correlation between the tenth nerve palsy and parvovirus infection is discussed.

To study clinical and EEG features of children with ictal vomiting and no underlying brain lesions (Panayiotopoulos syndrome). The subjects were 36 children aged 2-13 years. The onset of seizures occurred between 1 and 5 years of age. ⋯ No clinical differences were observed between patients having occipital or extraoccipital spikes. In children only with autonomic seizures, the spikes are predominantly occipital but blockage by opening of the eyes is a less frequent feature. In some children there is an overlapping of different focal childhood idiopathic syndromes.
