- Objectives
This study aims to evaluate the relationship between subjective dizziness disability, as assessed by the Dizziness Handicap Inventory (DHI), and objective vestibular function test (VFT) results in patients presenting with dizziness.
Methods
We conducted a retrospective review of 177 patients who completed the DHI, vertigo visual analog scale, and disability scale at their initial visit. Objective VFTs included videonystagmography with caloric testing, cervical vestibular evoked myogenic potential (cVEMP), and the sensory organization test (SOT). Statistical analyses were conducted to assess correlations and differences in DHI scores based on VFT results and clinical characteristics.
Results
The DHI scores indicated a higher perceived dizziness handicap among female patients compared to males (p=0.012). Chronic dizziness was associated with elevated DHI scores in specific items (DHI-2, DHI-12, and DHI-21; p<0.05). Patients with abnormal caloric responses exhibited higher scores in several DHI items and subscales (DHI-4, DHI-12, DHI-14, DHI-17, DHI-19, DHI-23, physical, emotional, and functional; p<0.05). No significant differences were found in cVEMP results. Only one SOT condition (equilibrium score 5) showed a statistically significant but weak association with DHI scores (r=–0.151, p=0.045).
Conclusions
There were limited correlations between objective vestibular test outcomes and subjective dizziness disability. These findings underscore the multidimensional nature of dizziness and the importance of integrating subjective and objective measures for a comprehensive clinical assessment.

Abstract

- Objectives
The influence of specific meteorological conditions, such as solar radiation quantity, duration of sunshine, and their covariation on the incidence of benign paroxysmal positional vertigo (BPPV) has been rarely investigated. Aiming at better predictions of the monthly variation of BPPV, we investigated variations in the monthly incidence of BPPV patients and meteorological parameters.
Methods
A total of 2,111 patients who had been diagnosed with BPPV at one institution were analyzed retrospectively. Monthly counts of BPPV patients were analyzed for incidence distributions throughout the 5 years. The relationship between intra-annual distribution of BPPV and meteorological parameters was compared by the time series analysis.
Results
The lowest monthly incidence of BPPV patients was found in September and the highest monthly incidence was found in December. Statistically, as a result of the time series analysis, a periodic fluctuation of both quantity of solar radiation (p=0.004) and percentage of sunshine duration (p=0.002) was identified, but a periodic fluctuation of both number of BPPV patients (p=0.316) and sunshine duration (p=0.057) was not identified.
Conclusions
Unlike previous studies, the results of time series analysis did not confirm that there is a periodic fluctuation in the incidence of BPPV patients. The incidence of BPPV may be more affected by other factors than by meteorological parameters.

Abstract
PDF
- Arnold-Chiari malformation type 1 is a congenital disease characterized by herniation of the cerebellar tonsils through the foramen magnum. Most common clinical symptom is pain, including occipital headache and neck pain, upper limb pain exacerbated by physical activity or valsalva maneuvers. Various otoneurological manifestations also occur in patients with the disease, which has usually associated with dizziness, vomiting, dysphagia, poor hand coordination, unsteady gait, numbness. Patients with Arnold-Chiari malformation may develop vertigo after spending some time with their head inclined on their trunk. Positional and down-beating nystagmus are common forms of nystagmus in them. We experienced a 12-year-old female who presented complaining of vertigo related to changes in head position which was initially misdiagnosed as a benign paroxysmal positional vertigo.

Abstract

- Objectives
Ménière disease is a clinical syndrome characterized by the four major symptoms of episodic vertigo, sensorineural hearing loss, tinnitus, and aural fullness. Sensorineural hearing loss, especially low frequency, is the characteristic type of audiogram in Ménière's disease. However, it is difficult to distinguish idiopathic sudden sensorineural hearing loss (ISSNHL) with vertigo from the first attack of Ménière disease. The purpose of this study was to investigate the incidence of progression into Ménière Disease from low frequency ISSNHL.
Methods
Two hundred eighty-three patients were included in this study. We classified the patients with ISSNHL according to the hearing loss in audiogram and analyzed how many of them actually progressed to Ménière disease based on diagnosis criteria.
Results
Among the 240 patients, 37.1% (89 patients) were confirmed low frequency ISSNHL and 14.6% (13 patients) of them were diagnosed with Meniere disease.
Conclusions
This study showed that the progression from low frequency ISSNHL to Ménière disease was higher than other frequency ISSNHL, as in other studies.
