    Notes: Abstract The purpose of this report is to analyze the long-term outcome in hydrocephalic children treated by shunt placement and in particular their psycho-intellectual development. In the case of shunt placement postoperative mortality is virtually nil, and the overall mortality rate after 10 years of follow-up has been reduced to less than 5%. Morbidity, in contrast, is far from satisfactory. This study was conducted in 129 consecutive children with nontumorous hydrocephalus who underwent a first shunt insertion before the age of 2 years between 1979 and 1982 and who were followed up for at least 10 years. The final neurological examination revealed a motor deficit in 60%, visual or auditory deficits in 25%, and epilepsy in 30%. The final IQs were above 90 in 32% of the children, between 70 and 90 in 28%, between 50 and 70 in 19%, and lower than 50 in 21%. Integration into the normal school system was possible for 60% of the children, but half of them were 1–2 years behind their age group or having difficulties; 31% were attending special classes or were in institutions; and 9% were considered ineducable. The presence of behavioral disorders was a determinant factor for scholastic and social integration. Such disorders were frequent, and were characterized as severe in 30%. A relationship between final outcome and etiology, initial ventricular size, and epilepsy was observed. These results are used as the basis of a discussion on how morbidity might be improved.

    Notes: Abstract Parkinson’s disease is a neurodegenerative disease characterised by a massive loss of dopaminergic neurons in the substantia nigra. Yet glial cells may also participate in the pathophysiology of the disease. Indeed, glial cells can produce trophic factors which may stimulate neuronal survival or, alternatively, they could produce toxic compounds which may be involved in neuronal degeneration. This paper reviews the potentially protective or deleterious effects of glial cells in the substantia nigra of patients with Parkinson’s disease.

    Notes: Abstract Colloidal dispersions in hydrocarbons of lead and calcium salts of isooctanoic acids are studied by means of Transmission Electron Microscopy and Light Scattering. The complementary results obtained, using each technique, allow us to investigate the structure of the mineral core, the size and the morphology of the colloidal particles. Special attention is paid to the aggregation properties of the metal salts particles as a function of the dilution and solvent.
