Vagus Nerve Ultrasonography Helps Distinguish Multiple System Atrophy from Other Parkinsonian Syndromes.

Background: Distinguishing multiple system atrophy from other parkinsonian syndromes is challenging.

Objectives: To evaluate vagus nerve ultrasonography for differentiating parkinsonian syndromes.

Methods: A single-center, cross-sectional, observational study assessed 85 consecutive adult patients with de novo parkinsonism between June 2020 and December 2022, using 12 MHz ultrasonography of the vagus nerve cross-sectional area.

Auto-brewery syndrome caused by oral fungi and periodontal disease bacteria.

Background: Auto-brewery syndrome (ABS) is often caused by fungi in the intestinal tract. We describe a rare case of alcohol production by and periodontal disease bacteria in the oral cavity.

Case Presentation: A man aged in his 60s had a car accident, and alcohol was detected on his breath.

Quantification of metal-induced susceptibility artifacts associated with ultrahigh-field magnetic resonance imaging of spinal implants.

Reports on spinal-implant metallic artifacts in 7-T magnetic resonance imaging (MRI) are lacking. Thus, we investigated the magnitude of metal artifacts derived from spinal implants in 7-T MRI and analyzed the differences obtained with spinal rods manufactured from pure titanium, titanium alloy, and cobalt-chrome (5.5-mm and 6.
