Subacute sclerosing panencephalitis after intrauterine infection.

UNLABELLED: Subacute sclerosing panencephalitis (SSPE), in the majority of cases, is caused by the wild measles virus, although there are some reports relating SSPE to vaccination. This paper presents an inborn that was infected during pregnancy by the measles virus and developed SSPE within the first year of life after a short incubation period. He progressed rapidly after a mild arrest with treatment. Subacute sclerosing panencephalitis is a fatal degenerative disease and, although it had largely disappeared because of nearly universal measles vaccination, it still remains a serious infection among children affected by human immunodeficiency virus (HIV). The lack of newer cases of SSPE occurring among normal children nowadays should not wane alertness by obstetricians and paediatricians, to recognize the risk with measles during pregnancy and the need for prevention and recognition of SSPE at an early stage. Although some references exist which report on SSPE cases related to vaccination, new work weakens the possible links between measles vaccine and SSPE. CONCLUSION: This report would like to stress the importance and success of reducing the SSPE problem with the aid of general measles vaccination with high coverage.

[Hereditary spongiform dystrophy in young children (Canavan: van Bogaert-Bertrand)]. / La dystrophie spongieuse héréditaire des enfants (Canavan: van Bogaert-Bertrand)

Hereditary spongiform dystrophy in young children is characterised by macrocephaly with spasticity, convulsions and ultimately a decerebrate state and diffuse electroencephalographic changes. Histological examination of the brain remains essential for its diagnosis. A review of the ultrastructural studies reported by various authors complements the findings obtained by conventional histology. We have thus endeavoured to determine whether van Bogaert-Bertrand's disease is to be considered as congenital or acquired. The anatomical findings in 3 cases together with the descriptions of other authors lead us to the following conclusions: -that the spongiform changes may be due to an osmolar disequilibrium in which the ATPase-Na/K relation with mitochondrial abnormalities is yet unclear. -that the constant finding of Alzheimer type II cells is certainly an indication of intra-astrocytic malfunction. -that the oedema blocks both myelin synthesis and its coiling into lamellae. Case 1, which showed a long survival compared to others described (about 4 years), enabled us to study terminal lesions. Sub-cortical zones, in both cerebrum and cerebellum, contained neither myelin nor spongiform cavities, but, on the other hand, showed a compact glio-fibrillosis with large vesicles and oligodendroglia of increased density. We have interpreted these lesions, progressively replaced by spongiosis deeper in the cortex, as evidence of retracted scar tissue. Differences found between cerebral weights seem to confirm this hypothesis.
