Objectives The aim of this study is to categorize headaches associated with definite Menière’s disease (MD) according to diagnostic criteria, to determine their prevalence, and to investigate the preferred medication across participating centers.
Methods Patients diagnosed with definite MD at 17 university hospitals in otolaryngology or neurology departments in Korea between January 1, 2021 to December 31, 2021 were retrospectively included. Data on the presence of accompanying vestibular migraine (VM), migraine or non-migraine headaches, and clinical information were collected. A survey was conducted to assess preferences for treatment drugs for vertigo and headache control in MD patients with headache.
Results A total of 435 definite MD patients were included, with a mean age of 57.0±14.9 years. Among them, 135 (31.0%) had accompanying headaches, of whom 48 (11.0% of all definite MD patients) could be diagnosed with VM. The prevalence of comorbid VM (definite and probable) was significantly higher in females (41 of 288, 14.2%) than in males (7 of 147, 4.8%) (p<0.05). There was no significant difference in the prevalence of comorbid VM between unilateral and bilateral MD patients (10.8% and 13.6%, respectively) (p > 0.05). Benzodiazepines, antihistamines, and antiemetics were mainly preferred for acute vertigo control, while nonsteroidal anti-inflammatory drugs, acetaminophen, and triptans were preferred for acute headache control, and topiramate, propranolol, and calcium channel blockers were mainly preferred for headache prevention.
Conclusions VM is not uncommon in patients with definite MD in Korea. Further research is needed to understand the differences in headache prevalence and preferred medications across different centers.
Autoimmune inner ear disease (AIED) is a rare disease, accounting for <1% of all cases of hearing impairment or dizziness. It is characterized by sensorineural hearing loss (SNHL) or vestibular dysfunction that results from an immunemediated process. Clinical features of AIED is SNHL that progresses over weeks to month with fluctuating hearing symptoms. Because there are no diagnostic laboratory and clinical feature, response to immunosuppressive therapy were important for diagnosis of AIED. Many diseases such as sudden SNHL and Meniere disease may also mimic AIED, a broad differential must be maintained in patients suspected of having AIED. We report a case of a 46-year-old female who presented with sudden hearing loss and vertigo. We could diagnose her as AIED with systemic lupus erythematous. The symptoms were improved treated with steroids.

Objective: There were few recent study concern about usefulness of cochlear hydrops analysis masking procedure (CHAMP) in progression of Ménièreʼs disease. The purpose of this study is to analyze changes in the CHAMP as advancement of Ménièreʼs disease.
Methods We studied 19 cases of ‘Definite’ group of Ménièreʼs disease. We assumed progression of Ménièreʼs disease would be checked by pure tone threshold by four tone average (4PTA), low tone average (LPTA). We also compared electrocochleography (ECoG), dizziness handicap inventory (DHI), tinnitus handicap inventory (THI) as parameters for progression of Ménièreʼs disease to CHAMP latency delay and amplitude ratio. Chi-square test was used as a statistical method.
Results In the group of patients had abnormal amplitude ratio, ECoG value were not improved, but there was not statistically significant (odds ratio [OR]=5.727, p>0.05). Better DHI and THI score were not necessarily construed as the improvement value in the CHAMP (p>0.05). In amplitude ratio abnormal group, 4PTA was aggravated, but not statistically significant (OR=1.5, p>0.05). In the group of patient had abnormality in both latency delay and amplitude ratio, LPTA was relatively aggravated (OR in latency delay: 2, OR in amplitude ratio: 10); however, reveals no statistically significance between them (p>0.05). Change of ECoG, hearing threshold including 4PTA and LPTA with progression of Ménièreʼs disease were not correlated significantly with latency delay or amplitude ratio of CHAMP.
Conclusion We conclude that CHAMP does not reflect clinical features with progression of Ménièreʼs disease.
It is known that endolymphatic hydrops is a pathophysiologic mechanism of Meniere’s disease, while the detailed role is not fully clarified. Study for endolymphatic hydrops mainly represents a pathologic histologic finding found only in the post-mortem examination of temporal bone, so endolymphatic hydrops animal models have played important role in terms of understanding how hydrops affects the function of the inner ear. Numerous challenges with diverse animals and techniques have been tried to reveal the possible pathophysiology of endolymphatic hydrops and develop an effective treatment. This review shows historical background and technical advances in experimental animal model for endolymphatic hydrops and Meniere’s disease.
Benign paroxysmal positioning vertigo (BPPV) is the most common disease that causes dizziness which is usually resolved spontaneously or by office-based physical therapy.
However, clinicians sometimes encounter atypical or intractable BPPV cases which show poor effect with physical therapy including canalith reposition therapy and liberative maneuvers and frequent recurrence. There is no common definition, diagnosis and treatment protocols for intractable BPPV. Various types of intractable BPPV and reported treatment methods are discussed in this review.
As it is difficult to perform biological study in the actual space, several researchers
have tried to develop methods that could ‘mimic’ microgravity condition
on Earth. During the free fall of the aircraft, so-called ‘parabolic flight’, objects
in a plane could experience weightlessness during a short period of time (approximately
20 to 30 seconds). We first reviewed former studies using parabolic flight
in a variety of research filed including vestibular, neurologic, cardiovascular, musculoskeletal
and immune system. We also investigated the actual conditions of
biologic research using parabolic flight in Korea, by performing a questionnaire
survey for 19 experts in space biology.
