ATAXIC ARSENICAL NEURITIS WITH LOSS OF OSSEOUS SENSIBILITY

Arsenical Neuritis

use of impure acids containing arsenic used for the manufacture of glucose and " invert" sugar. The number of cases amounted to over 6,000 and of deaths to at least 70. Many deaths returned as due to, "alcoholic neuritis" "alcoholism," "locomotor ataxy," &c., were probably caused by arsenical poisoning. Since the exposure of the cause of the outbreak and discontinuance of the use of impure acid...

Arsenical polyneuropathy due to caustic arsenical paste.

Dysequilibrium/ataxic diplegia with immunodeficiency.

A girl with purine nucleoside phosphorylase (PNP) deficiency is described. The nature of the motor disorder is similar to other children since found to have PNP deficiency. It is suggested that the diagnosis be considered in any child with unexplained dysequilibrium/ataxic diplegia. Other previously unreported features are intracytoplasmic neutrophil inclusion bodies and an improvement in the n...

Alkaline Reactivity of Arsenical Natrojarosite

Jarosites são compostos que podem sofrer substituições com vários elementos de importância ambiental (tais como As) durante a precipitação. Arsênico integrado na estrutura poderia influenciar a solubilidade da jarosita, potencialmente estabilizando a estrutura em uma ampla gama de condições que são toleradas pela jarosita pura. A reatividade álcali é caracterizada pela remoção de íons sulfato e...

Magnetisation transfer ratio in optic neuritis is associated with axonal loss, but not with demyelination

BACKGROUND Pathophysiological basis of Magnetisation Transfer Ratio (MTR) reduction in multiple sclerosis still remains a matter of controversy. Optic nerve represents an ideal model to study the consequences of axonal loss and demyelination on MTR since effects of disease on the optic nerve are clinically apparent and potentially quantifiable by objective means. By measuring the latency of mul...
