Background: The International Classification of Vestibular Disorders defines probable vestibular migraine (PVM) as an episodic vestibular disorder with either a history of migraine (criterion B) or migraine features during vestibular episodes (criterion C).
Objective: The purpose of this study is to investigate the clinical characteristics of PVM, focusing on items in the diagnostic criteria.
Methods: We retrospectively reviewed the medical records of 30 consecutive PVM patients diagnosed according to the Barany classification.
Objective: This multicenter, randomized, double-blind, placebo-controlled, crossover trial aimed to evaluate whether prolonged noisy galvanic vestibular stimulation improves body balance in patients with vestibulopathy.
Materials And Methods: This trial was registered in the Japan Pharmaceutical Information Center Clinical Trials Information registry (jRCT1080224083). Subjects were 20- to 85-year-old patients who had been unsteady for more than one year and whose symptoms had persisted despite more than six months of rehabilitation.
Introduction: It is unknown whether prodromal dizziness (PD) before an attack of vestibular neuritis (VN) has an association with peripheral vestibular lesions. The purpose of this study was to investigate whether the severity of vestibular dysfunction has an association with the presence of PD.
Methods: We reviewed the medical records of 88 consecutive unilateral VN patients with unilateral canal paresis in caloric testing.
Article Synopsis
- The study aimed to assess postural stability in patients with vestibular migraine (VM) and probable vestibular migraine (PVM) without acute symptoms by analyzing their performance on foam posturography tests.
- A total of 30 VM patients, 25 PVM patients, and 194 healthy controls were evaluated, with factors such as age, sex, and diagnosis being analyzed for their impact on postural stability.
- Results indicated that both VM and PVM patients exhibited greater postural instability compared to healthy controls; however, there were no significant stability differences between the two patient groups.
Article Synopsis
- PPPD (Persistent postural-perceptual dizziness) patients experience worsened symptoms when standing, moving, or exposed to visual stimuli.
- A study evaluated postural stability in 53 PPPD patients using foam posturography, comparing results with healthy controls.
- Findings indicated that PPPD patients relied more on visual cues and less on somatosensory input when standing, regardless of their vestibular function, highlighting unique balance control dynamics.
Background: The reproducibility of the effective intensity of noisy galvanic vestibular stimulation (nGVS) to improve postural stability is not well known.
Objective: We aimed to investigate inter-day and intra-day variations in effective intensity in patients with bilateral vestibulopathy (BVP).
Methods: Thirteen BVP patients were measured for center-of-pressure movements in the standing posture at five time points: morning of the first test day, morning and evening of the second test day, and morning and evening of the third test day.

Objective: To investigate the effects of self-management vestibular rehabilitation (VR) on the subjective symptoms of dizziness and postural stability in persistent postural-perceptual dizziness (PPPD).
Study Design: Retrospective case review.
Methods: The medical records of 30 patients newly diagnosed with PPPD based on the Bárány Society's diagnostic criteria were reviewed.
Persistent postural-perceptual dizziness (PPPD) is induced by preceding conditions that cause balance disorders. To investigate the association between vestibular function and preceding balance disorders in PPPD patients, a retrospective chart review was performed. Vestibular function in 55 PPPD patients was measured using the caloric test, cervical vestibular evoked myogenic potential testing to air-conducted sound (ACS cVEMP), ocular vestibular evoked myogenic potential testing to bone-conducted vibration (BCV oVEMP), and video head impulse testing (vHIT).

The purpose of the present study is to examine whether the dominant cVEMP responses at 1000 Hz over 500 Hz are characteristic findings of EH-related diseases among patients who show various cVEMP findings.
Design: We retrospectively reviewed the medical records of 470 consecutive patients who underwent cVEMP testing with short-tone bursts at both 500 Hz and 1000 Hz.
Objective: To determine minimally important differences (MIDs) for subjective improvement in postural stability after a therapeutic intervention in patients with bilateral vestibulopathy (BVP).
Methods: Thirteen BVP patients received noisy galvanic vestibular stimulation (nGVS) for 30 min and their static posture with eyes closed was monitored after the stimuli. The velocity of the center of pressure (COP) movement, the area enclosed by the COP movement, and the root mean square (RMS) of the displacement of the COP were measured for 30 s.
Introduction: Fibrovascular polyps (FVPs) are benign tumors that commonly occur in the cervical esophagus. Few cases of FVPs of the hypopharynx have been reported, but there has been no English review concerning hypopharyngeal FVPs (hFVPs). Here, we report a case of a vast hFVP, and we also review 13 hFVP cases found in the English literature (PubMed search) including our case.

Here, we report the diagnosis, symptoms, treatment, and postoperative complications of 44 substernal goiters (2 primary mediastinal goiter and 42 secondary mediastinal goiters).
Methods: A retrospective chart review of 351 patients undergoing thyroidectomy at the Department of Otolaryngology-Head and Neck Surgery of the Tokyo Metropolitan Tama Medical Center.
Article Synopsis
- * Researchers reviewed records from 2009 to 2015, identifying 38 cases out of 798 primary tuberculosis patients, with a nearly equal male-to-female ratio and a wide age range.
- * Results showed that 86.8% were cured with chemotherapy, while surgery (neck dissection) was effective for the 3 patients resistant to drugs; overall, 94.7% showed improvement through either treatment method.
