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.

Ethidium-bromide (EB)-induced lesions have been used to investigate the incomplete remyelination in the central nervous system, as well as to evaluate therapeutic strategies to accelerate the reconstruction of the lost myelin sheaths. Although many electrophysiologic studies were performed in situations of experimental demyelination and remyelination, their behavioural effects have not been properly analyzed. In this study, we investigated ultrastructurally the EB - demyelinating lesions as well as the locomotor activity of rats during the beam walking test after a focal induction of demyelination using the EB model in the ventral surface of the brainstem. It was observed the occurrence of locomotor deficits until 31 days post-injection, as well as that subsequent remyelination was related to the return of the lost function.

To analyze the demographic features of the population sample, the time of headache complaint until first consultation and the diagnosis of primary and secondary headaches. ⋯ There are few data on epidemiological features of headache clinic populations, mainly in developing countries. According to the literature, migraine was more frequent than TTH. It is noteworthy the low school instruction of this sample and time patient spent to seek for specialized attention. Hypnic headache syndrome was seen with an unusual frequency.

Biochemical markers have played an increasingly relevant role in the assessment of neonatal asphyxia. The S100B protein is particularly important in research conducted in this field. The purpose of this study was to underline the importance of the S100B protein in the assessment of term newborn infants with hypoxic-ischemic encephalopathy, as well as to relate it to other substances also involved in the ischemic process. ⋯ Samples were collected on the 1st and 4th day of life and S100B protein and lactate concentrations were calculated using the immune cytochemical method. A positive relationship was found between the two substances. Additionally, a comparison between the two substances showed a statistically significant correlation.

Occipital bi-transtentorial/falcine approach for falcotentorial meningioma: case report.
Lesions located in the bilateral posterior incisural space are difficult to treat due to limited exposure. The classical approaches to this area are limited for lesions located bilaterally and especially when the lesion extends also below the tentorium as it may occur with meningiomas. ⋯ We present a patient with a large falcotentorial meningioma, located bilaterally in the posterior incisural space. The occipital bi-transtentorial/falcine approach allowed an excellent surgical exposure and complete tumor removal with an excellent patient outcome.
