Background: The aim of this study was to investigate the potential role of video head impulse test (vHIT) in the detection of brainstem lesions in patients with multiple sclerosis (MS).
Methods: Sixty-eight participants were enrolled and divided into two groups: 39 healthy subjects (HC) (78 ears, 20 females, mean age 25,3±6,3) and 29 MS patients (58 ears, 14 females, mean age 33,7±7,7). Both groups underwent vHIT, and in MS group MRI was analyzed for the presence of brainstem lesions. vHIT pathology was defined as presence of overt saccades (<200ms) or lateral gain lower than 0.8 for lateral canal, and presence of overt saccades (<200ms) or posterior/anterior slope lower than 0.7.
Results: In HC, decreased gain on horizontal canals was found in 8 out of 78 ears (11%), while 16 out of 58 ears (38%) had pathological results in the MS group. Mean gain of the lateral canals (60ms) was significantly reduced in MS group compared to HC (0.874±0143 vs. 0.954±0,170, p=0.004, respectively). Compared to HC overt saccades <200ms in the lateral canals (p=0.018) and in the posterior canals (p=0.011), overt saccades >200ms in lateral (p<0.001), anterior (p=0.019) and posterior canals (p=0.009), and covert saccades in the anterior (p=0.042) and posterior canals (p=0.046) were more frequent in the MS group. There was statistically significant association between the presence of BS MR lesions and bilateral pathology on vHIT for lateral semicircular canal (χ(1)=3.982, p=0.046).
Conclusion: These results indicate that vHIT can detect brainstem dysfunction in patients with MS.

One of the main endpoints for the evaluation of Developmental and Reproductive Toxicology (DART) studies is the determination of potential effects of a test substance on the skeleton during foetal development. In the course of a DART study according to the OECD 414 guideline, 400 to 500 gestational day 20-old (GD20), alizarin red and alcian blue-stained (ARAB) rat foetuses have to be assessed by a teratology expert, which is a time consuming and sub-optimally documented process. We have developed a method which allows for a standardised, comprehensive, quick and easy to perform, head-to-toe digital documentation of ARAB-stained GD20 rat foetuses.

Objective: The study aimed to explore the vestibular function in children with neurodevelopmental disorders (NDDs).
Methods: Twenty-eight participants with a NDD (6 girls, 22 boys; 6-13 years; 9;3 ± 2;4 years) were enrolled in this pilot study. Sixteen participants had a single NDD (Autism Spectrum Disorder: n = 7, Developmental Coordination Disorder: n = 3; Attention Deficit/Hyperactivity Disorder: n = 6), the remaining 12 had comorbid NDDs.

To analyse the 3D-Flair MRI manifestations of the inner ear, vestibular function status, and their correlation with hearing treatment outcomes in patients with severe sudden sensorineural hearing loss (SSNHL), and to explore potential prognostic indicators for sudden deafness. The clinical data of adult patients with unilateral profound sudden sensorineural hearing loss were retrospectively analyzed in Otorhinolaryngology Department of Shandong Provincial ENT Hospital from March 2018 to August 2020. Patients were categorized based on the results of their inner ear 3D-Flair MRI into two groups: the normal MRI group and the abnormal MRI group.

Purpose: Head acceleration events (HAEs) are a growing concern in contact sports, prompting two rugby governing bodies to mandate instrumented mouthguards (iMGs). This has resulted in an influx of data imposing financial and time constraints. This study presents two computational methods that leverage a dataset of video-coded match events: cross-correlation synchronisation aligns iMG data to a video recording, by providing playback timestamps for each HAE, enabling analysts to locate them in video footage; and post-synchronisation event matching identifies the coded match event (e.
