RESUMO
A patient had paralysis of multiple lower cranial nerves (VII, IX, X, XI, and XII) and oculosympathetic fibers, and ipsilateral conductive hearing loss. Histologic analysis of a surgical biopsy of the temporal bone revealed metastatic adenocarcinoma of prostatic origin. This is only the second reported case in the English literature (seventh in the world literature) of prostatic adenocarcinoma metastasizing to the temporal bone.

Studies of the diffuse electroretinogram (ERG) and evoked reponses in the optic lobe in the baby chick have shown that epinephrine produces changes in both. Epinephrine produces enhancement of the a-wave and depression of the b- and d-waves in both intact and isolated eyes. In the optic lobe it produces enhancement of both components of the evoked response. The presence of epinephrine in the vertebrate retina and the optic lobe of chicks suggests that these changes may reflect the involvement of epinephrine in synaptic transmission.
