Abstract: There are a number of reports on the pathologies of vestibular disorders. However, these studies included only a few examples, which were not quantitative but merely anecdotal or descriptive. However, a single tissue section may be relevant to a specific disease in multiple ways. The histopathological characteristics of common peripheral vestibulopathies, including benign paroxysmal positional vertigo, Ménière’s syndrome, labyrinthitis, vestibular neuritis, and ototoxicity, have been described. A recent study validated a new quantitative method for determining vestibular otopathology. Detailed quantitative analyses of vestibular pathology are required to obtain a deeper understanding of the vestibular system. Such studies will likely reveal the pathophysiological causes of specific diseases by elucidating the correlations between structural and functional features. Therefore, histopathological studies of vestibular disorders should be performed.

Objectives
Vertigo is considered a poor prognostic factor in patients with sudden sensorineural hearing loss (SSNHL). Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo and may accompany SSNHL. However, whether BPPV is a poor prognostic factor remains controversial. We identified features of prognostic utility in patients with both SSNHL and BPPV. Methods: We retrospectively evaluated data on all patients diagnosed with SSNHL at Keimyung University Dongsan Medical Center between January 2011 and December 2015. We reviewed medical records, the results of vestibular function testing, and audiographic data. Results: Of the 524 idiopathic SSNHL patients, 20 (3.8%) were also diagnosed with unilateral BPPV. The average pure tone average (PTA) of those with both SSNHL and BPPV was higher than that of those without BPPV. Of the 471 patients with SSNHL only, 143 (30%) exhibited complete recovery. Of the 33 SSNHL patients with vertigo, 3 (9%) exhibited complete recovery, but only 3 (15%) of those with both SSNHL and BPPV exhibited complete recovery. Of the 20 patients with both SSNHL and BPPV, 15 had ipsilateral BPPV and 5 contralateral BPPV. Conclusions: Patients with BPPV had a higher average initial PTA score and poorer hearing recovery after treatment, than patients with SSNHL alone. Patients with contralateral BPPV had a somewhat better prognosis than those with ipsilateral BPPV, but statistical significance was not attained.

Abstract: Falls are the most common cause of accidents among the older population, leading to both fatal and non-fatal injuries. Falls is a syndrome resulting from the cumulative effect of various extrinsic and intrinsic factors. It is considered to be a multifactorial disorder. Medication use is considered a risk factor for falls. We reviewed medications associated with falls in older individuals. In geriatrics populations, polypharmacy is associated with falls. Medical doctors should be aware of the possibility that starting a new medication, such as antihypertensive agents, benzodiazepine, antidepressants, opioid agents and antihistamines, may act as a trigger for the onset of a fall.
