Neurotological Findings in a Patient with Glufosinate Ammonium Intoxication: Ji Young Kim, Joo Yeon Ham, Seong-Hae Jeong; Res Vestib Sci. 2020;19(4):138-140. Published online December 15, 2020; DOI: https://doi.org/10.21790/rvs.2020.19.4.138

Abstract PDF Supplementary Material: The upward deviation could be explained by loss of inhibitory inputs from the cerebellum onto the brainstem anterior semicircular canal projections for upward vestibulo-ocular reflex, which would lead to an upward bias in static eye position. Therefore, upward gaze deviation has been reported in comatose patients after resuscitation and diffuse cerebrocerebellar damage sparing the brainstem. Herein, we report a patient with ingestion of glufosinate ammonium presented with cerebellar ataxia and ocular motor findings suggestive of cerebellum involvement such as upward gaze tendency, spontaneous downbeat, gaze-evoked nystagmus, perverted head impulse test, and impaired smooth pursuit.

A Case of Unilateral Internal Carotid Artery Stenosis Presenting with Chronic Isolated Dizziness: Ju Heon Lee, Seong Hae Jeong, Young Gi Lim, Joo Yeon Ham, Hye Seon Jeong, Jae Moon Kim; Res Vestib Sci. 2016;15(2):60-63. Published online June 15, 2016

Abstract PDF: It is customary that the dizziness related to cerebral perfusion might be caused by insufficient posterior circulation. The occurrence and nature of dizziness originating from anterior circulation has not been well-known. Here, we report a chronic dizzy woman presenting with severe internal carotid artery stenosis, which improved after carotid artery stenting.
