Delayed visual maturation and lead pollution.

Three children were born in the Broken Hill Australia lead mining community with delayed visual maturation of the optic nerve (blindness) within a period of 19 months. Because of the association with the lead pollution, the delayed visual maturation was attributed to lead exposure of the fetus during pregnancy. Lead isotopic analyses of the shed deciduous teeth from the three children demonstrate that they were not exposed to increased levels of lead from a mining or any other source during pregnancy and the etiology of the delayed visual maturation must be sought elsewhere.

Limb paralysis as a manifestation of Coxsackie B virus infection.

Forty-four African children (25 girls, 19 boys) are described with single or multiple limb paralysis as a manifestation of infection with Coxsackie B virus. Single limb paralysis involved exclusively the lower extremity, with no nervous system involvement elsewhere and a relatively benign prognosis. Multiple limb paralysis occurred either alone or with other neurological deficits. Only two of 15 patients followed up for five months or longer regained premorbid motor status. Seven patients required assisted ventilation, of whom all but one died. Viral infection remains an important cause of acute limb paralysis in this population, and Coxsackie B is the agent often responsible.
