Introduction Vestibular pathologies cause physical and psychological symptoms, as well as cognitive problems. Objective To evaluate the deterioration in sleep quality associated with vestibular pathologies. Methods The Dizziness Handicap Inventory (DHI), the Beck Depression Inventory (BDI), the Pittsburgh Sleep Quality Index (PSQI), and the Limits of Stability test (LOS) were applied to the participants. Results We included 25 patients with Meniere's disease (MD), 22 patients with benign paroxysmal positional vertigo (BPPV), 21 patients with unilateral peripheral vestibular loss (UPVL), 23 patients with vestibular migraine (VM), and 43 controls. The total PSQI scores of the controls were better than those of the MD (p = 0.014), VM (p < 0.001), BPPV (p = 0.003), and UPVL (p = 0.001) groups. The proportion of poor sleepers in the MD (p = 0.005), BPPV (p = 0.018), and UPVL (p < 0.001) groups was significantly higher than that of the controls. The highest total DHI score (45.68 ± 25.76) was found among the MD group, and it was significantly higher than the scores of the BPPV (p = 0.007) and control (p < 0.001) groups. The highest BDI score was obtained in the VM group, and it was significantly higher than the scores of the BPPV (p = 0.046) and control (p < 0.001) groups. Moreover, the BDI scores of the MD (p = 0.001) and UPVL groups were also significantly worse than the score of the controls (p = 0.001). Conclusion The present study showed thatpatients with vestibular symptoms have physical and functional complaints, as well as increased psychosocial stress and decreased sleep quality. Evaluating multiple parameters of quality of life may contribute to a better understanding of vestibular physiology and symptoms, and may help establish a more effective therapeutic approach.

Purpose: The purpose of this study was to describe hearing health care and education experiences of children with cochlear implants (CIs) during the COVID-19 pandemic and the potential psychosocial effects of the pandemic on these children and their parents/family members. Method: The study used a cross-sectional survey design. The study sample comprised two groups, namely, parents/family members of children with CIs (study group, n = 70, M age = 44.6 ± 12.4 years) and parents/family members of children with normal hearing (control group, n = 58, M age = 43.8 ± 11.5 years). Parents/family members completed the Perceived Stress Scale (PSS), the Coronavirus Anxiety Scale (CAS), and the Family Perspective Profile form, as well as the Demographic Information form. Results: The PSS scores of the study group were higher than those of the control group ( p = .001). However, there was no statistically significant difference between groups in the CAS scores ( p = .896). According to the Family Perspective Profile form, almost half of the parents/family members of children with CIs reported that their children experienced difficulties in education and hearing health care services during the pandemic and showed some changes in their attitudes and behaviors. Conclusions: During the pandemic, the stress levels of parents/family members of children with CIs were higher than parents/family members of children with normal hearing. In addition to the challenges posed by the pandemic, the difficulties that parents/family members of children with CIs experience in meeting their children's additional needs related to accessing education and hearing health care services may have contributed to increased stress levels.

To investigate the effect of different types of convergent strabismus on horizontal eye movements and compare data with healthy control subjects.This prospective, cross-sectional study included 38 patients with convergent strabismus (16 fully accommodative, 13 partially accommodative and 9 non-accommodative esotropia) and 19 age-matched control subjects. All of the participants had a detailed ophthalmological examination including visual acuity assessment, cover-uncover prism test, slit lamp, and indirect ophthalmoscopy examination. Videonystagmography (VNG) was used for the evaluation of horizontal eye movements such as saccadic accuracy, velocity, latency, and smooth pursuit velocity gain.The saccadic accuracy in the rightward direction was lower in the fully accommodative esotropia group compared to the partially accommodative esotropia group in the right eye (p = 0.002). The saccadic latency in the rightward direction was longer in the fully accommodative esotropia group compared to the control group (p = 0.008) and smooth pursuit velocity gain in the leftward direction was lower in the partially and non-accommodative esotropia group compared to the control group in binocular recording (p = 0.004, p = 0.001, respectively). There was no difference in the saccadic velocity among the study groups (p 0.05). Finally, asymmetry of saccadic velocity and latency was observed between right- and leftward directions in the partially accommodative esotropia group in the right eye (p = 0.003, p = 0.008, respectively).This study demonstrated that horizontal eye movements may vary in different types of convergent strabismus. VNG may be an auxiliary tool to the clinical examination in differentiating fully or non-accommodative esotropia.

Objective The video head impulse test (vHIT) is a diagnostic tool to assess the function of the semicircular canals and branches of the vestibular nerve. The aim of this study was to analyze the interexaminer variability of vHIT results in healthy subjects. Materials and Methods A total of 21 healthy participants were included in the study. vHIT responses were collected by four clinicians. Variability of the vHIT results between examiners was analyzed statistically. Results The vestibulo-ocular reflex (VOR) velocity regression values were from 0.99 to 1.09 degrees per second for the lateral canals. For the vertical canals, VOR velocity regression values were from 0.87 to 1.21 degrees per second. According to repeated measures analysis of variance, the normality assumptions for the velocity regression of the left lateral canal (p = 0.002) and the right anterior canal (p Conclusion The interexaminer differences of the VOR gain values for the vHIT were statistically significant. Serial vHIT testing should be performed by the same examiner to reduce the effects of interexaminer variability.
