A case of neglect.

In 1875 William Andrew Johnson, who had been formerly enslaved by Andrew Johnson and who subsequently served as his valet after being emancipated, was present when the former president suffered his fatal stroke. William's description of his deficits, as told decades later to journalist Ernie Pyle, appears to represent one of the earliest known cases of asomatognosia. The limited description of the symptoms provides a backdrop for a discussion of the evolution of knowledge regarding disorders of body awareness.

Retrolaminar Migration of Intraocular Silicone Oil.

Background: Migration of intravitreal silicone to the retrolaminar optic nerve was detected pathologically in 1983, symptomatic migration to the subarachnoid space of the optic nerve was reported in 1994, and asymptomatic intraventricular silicone was first seen radiographically in 1999. Since then, little advance has been made in understanding this phenomenon despite numerous case reports. Although some authors have restricted their attention to cases of intraventricular silicone, we believe that these represent part of a clinical spectrum and that all cases with retrolaminar silicone should be considered.
