Multicenter study of childhood headache.

This multicenter study reports the results obtained between 1990 and 1991 by the Study Group for Childhood Headache of the Italian Neuropediatric Society. Standardized computerized case sheets were used in order to increase the number of young patients studied and obtain more homogeneous results. A clinical diagnosis of headache was made in 600 patients (314 female and 286 male) between 4 and 12 years of age, in accordance with the classification set down by the International Headache Society.

Massive neuronal destruction in human immunodeficiency virus (HIV) encephalitis. A clinico-pathological study of a pediatric case.

Human immunodeficiency virus (HIV) encephalitis in children with AIDS includes a diffuse white matter disease associated with an inflammatory cell infiltrate that features multinucleated giant cells. Cerebral cortex is relatively preserved and only focal loss of Purkinje cells in the cerebellum has been observed. We describe a case of encephalitis in a child with AIDS in which there was massive and diffuse destruction of the cerebral cortex with severe neuronal loss, marked inflammatory perivascular infiltrate with abundant multinucleated cells and large pleomorphic reactive astrocytes.

Rectal administration of sodium valproate in children.

A study of VPA based on a comparison of mean plasma levels, plasma peak latency times and plasma half-lives after rectal and oral administration was conducted in 9 children between 6 months and 10 years of age suffering from various forms of epileptic seizure, before they received chronic VPA treatment. Each child received an oral dose of 20 mg/kg and after two days a rectal dose of 20 mg/kg and the mean plasma concentrations were determined at intervals for both modes of administration. An identical plasma concentration for both after 24 h showed that the quantity of drug absorbed was the same.

Behçet syndrome: report of two early-onset cases treated with transfer factor.

Report of two cases of Behçet syndrome in children, one with the features of a neuro-Behçet syndrome and the other with chiefly severe ocular changes. Both children were treated with transfer factor when previous treatment had proved ineffective. Some years after the beginning of treatment, which is still continuing, transfer factor may be said to be of value in Behçet syndrome.

[Plasma and platelet serotonin in children with essential headache].

We examined the haematic concentration of 5 HT in idiopathic headache in children. We observed plasma and platelet 5 HT concentration in 18 migrainous patients free from painful crisis, and we compared the results with a control group of 20 clinically healthy children. No significant variation was noted in plasma 5 HT concentration between the two groups.
