Association Between Vitamin E and Handgrip Strength in the Korean General Population in KNHANES VII (2018)

Objective@#To investigate the association between vitamin E and handgrip strength (HGS) with multiple factors. @*Methods@#A total of 1,814 participants were included (822 men and 981 women) from the Korean subjects of the 7th Korea National Health and Nutrition Examination Survey in 2018. Data were analyzed using multiple logistic regression to determine the correlation between vitamin E and HGS with potential confounding factors. @*Results@#In the multiple logistic regression model, only the young age group (19–40 years) of men showed a positive relationship between vitamin E and HGS. However, in older age groups (41–80 years) of men and all age groups of women, there was no statistically significant result. After adjusting for confounding factors, young men showed higher vitamin E levels and higher HGS. Conversely, women and older age groups did not show significant results after adjusting for confounding factors. @*Conclusion@#In this study, the serum vitamin E level had a positive effect on HGS in young men (<40 years). Further research is needed on this topic regarding vitamin E intake and other objective measures.

A Long-Term Follow-up of Pontine Hemorrhage With Hearing Loss

A pontine intracranial hemorrhage (ICH) evokes several neurological symptoms, due to the various nuclei and nerve fibers; however, hearing loss from a pontine ICH is rare. We have experienced a non-traumatic pontine ICH patient, with hearing loss. A 43-year-old male patient had a massive pontine hemorrhage; his brain magnetic resonance imaging revealed the hemorrhage on the bilateral dorsal pons, with the involvement of the trapezoid body. Also, profound hearing loss on the pure-tone audiogram and abnormal brainstem auditory evoked potential were noticed. Fifty-two months of long-term follow-up did not reveal any definite improvement on the patient's hearing ability.

Simultaneous Loss of Bilateral Voluntary Eyelid Opening and Sustained Winking Response Following Bilateral Posterior Cerebral Artery Infarction

Spontaneous opening and closing of both eyes usually occurs in the normal awake state, unless a deliberate and voluntary attempt is made to open only one eye. We present a rare case of a male patient who was unable to open both eyes simultaneously after bilateral posterior cerebral artery infarction. He was able to close both eyes voluntarily. However, he was unable to keep both eyes open simultaneously and either the right or left eye remained closed. Upon a verbal command to open both eyes, the opened eye closed and the contralateral eye opened. When the closed eye was forced open, the opened eye closed. We thus presented a case of right-left dissociation of voluntary eyelid opening following bilateral posterior cerebral artery infarction, which was treated with botulinum toxin type A injection. Differential diagnosis to other movement disorders of the eyelids was discussed.

Trial of Metoclopramide on Oro-facial Dyskinesia Following Traumatic Brain Injury: A Case Report

Oro-facial dyskinesia is characterized by involuntary repetitive movements of the tongue, lip, or jaw, which is known to be derived by variable causes. Pre- and post-synaptic dopamine receptor abnormalities by degenerative changes in the brain seem to be the key pathophysiology, but the exact mechanism still remained to be unknown. Metoclopramide can pass the blood-brain barrier, which is known for a selective presynaptic autoregulating dopamine D2 receptor antagonist in the brain, and is usually prescribed for dyspepsia, nausea and vomiting. In particular, it was also reported to improve the symptoms of diurnal bruxism after brain injury. With reviewing some of literatures, we present a case of 27 year old man with traumatic brain injury who showed improvement of oro-facial dyskinesia after taking oral metoclopramide.
