Article Synopsis
  • This study examined the symptoms and impacts of Meniere's disease (MD) on patient quality of life (QoL), focusing on the frequency and intensity of vertigo episodes and how these evolve over time.* ! -
  • Conducted with 365 participants using an online questionnaire, the research found that many experienced a delayed diagnosis of over five years, with a notable percentage reporting spontaneous remission from vertigo over the disease's course.* ! -
  • Key findings showed that symptoms such as balance issues, fatigue, anxiety, and cognitive impairments affected younger patients significantly, leading to a poorer QoL, particularly among those suffering from constant dizziness.* !

Article Synopsis
  • - The study focused on examining dizziness and vertigo in patients with Ménière's disease (MD) through a retrospective survey involving 539 participants and a detailed online questionnaire assessing symptoms and quality of life.
  • - Findings revealed that a significant portion of patients experience varying levels of dizziness: 46% had episodic vertigo, 6% had constant dizziness, and 31% experienced no dizziness or vertigo in the past two years, highlighting the varied impacts on their health-related quality of life (HRQoL).
  • - Constant dizziness was linked to several challenges including cognitive problems, fatigue, and severe balance issues, with the study suggesting that different types of dizziness may require tailored treatment approaches to manage symptoms effectively, although optimal

The aim of the present study was to investigate adverse effects of head injury, neck trauma, and chronic noise exposure on the complaint profile in people with Ménière's disease (MD). The study used a retrospective design. Register data of 912 patients with MD from the Finnish Ménière Federation database were studied.

Background: The aim of the current study was to explore the associations among different therapeutic procedures, self-administered exercise, and characteristics of Ménière's disease.

Methods: The study used a retrospective design and included 539 people with Ménière's disease who were focusing on self-administered exercise. The mean age and history of Ménière's disease among these participants were 61.

Background: The mechanisms of Meniere's disease (MD) remain largely unknown. The purpose of this study was to identify possible genetic variants associated with immune regulation in MD.

Methods: The whole immune genome of 16 Chinese patients diagnosed with sporadic MD was sequenced using next-generation sequencing.

Introduction: Our previous work indicated that the activation of the Toll-like receptor (TLR) 4 signaling pathway contributed to noise-induced cochlear inflammation. Previous studies have reported that low-molecular-weight hyaluronic acid (LMW-HA) accumulates during aseptic trauma and promotes inflammation by activating the TLR4 signaling pathway. We hypothesized that LMW-HA or enzymes synthesizing or degrading HA might be involved in noise-induced cochlear inflammation.

The association between reporting adverse coronavirus disease 2019 (COVID-19) vaccination effects and those with a history of audiovestibular difficulties is unknown. The aim of this research is therefore to investigate adverse vaccination effects in adults with a history of Ménière's disease. Specifically, the incidence of adverse effects, the factors associated with those reporting adverse effects and the relationship between the reporting of audiovestibular and other adverse effects.

The etiology and mechanism causing Meniere's disease (MD) are not understood. The present study investigated the possible molecular mechanism of autoimmunity and autoinflammation associated with MD. Thirty-eight patients with definite MD and 39 normal volunteers were recruited, and 48 human cytokines/chemokines were quantified.

Background: Intratympanic administration of gadolinium chelate allows for a better visualization of endolymphatic hydrops (EH) using MRI than intravenous injection and was recently further improved to facilitate high-quality imaging of EH in 7 min. The aim of the present study was to simplify the intratympanic administration protocol by mixing gadolinium chelate with therapeutic dexamethasone and to evaluate the effects of this mixture on the visualization of EH in MRI.

Materials And Methods: In an in vitro study, the potential impact of gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) on the stability of dexamethasone was evaluated by analyzing dynamic changes in dexamethasone with high-performance liquid chromatography (HPLC) after mixing with Gd-DTPA.

The etiology and underlying mechanism of Meniere's disease (MD) development are still unknown, although inflammation and autoimmunity have been implicated as underlying mechanisms. The human endolymphatic sac (ES) has been reported to have innate and adaptive immune capacity in local immune reactions. In vivo demonstration of inflammation of the ES in patients with MD is missing in the literature.

Intratympanic(IT) drug delivery receives attention due to its effectivity in treatment for Menière's disease(MD). Due to the release of the consensuses and new evidence on IT drug delivery for MD have been published, the review with a view to supplementing the details of IT treatment of MD is indispensable. The literatures on IT injection for MD treatment over the last two decades are retrieved, International consensus(ICON) on treatment of Menière's disease(2018), Clinical Practice Guideline(2020) and European Position statement on Diagnosis and Treatment of Menière's disease(2018) are taken into account for reference, and follow advice from experts from Europe, USA and China.

Endolymphatic hydrops (EH) is considered the histological hallmark of Meniere's disease. Visualization of EH has been achieved by special sequences of inner ear magnetic resonance imaging (MRI) with a gadolinium-based contrast agent intravenous or intratympanic administration. Although it has been applied for more than 10 years since 2007, a unified view on this technique has not yet been achieved.

Background: It is still challenging to detect endolymphatic hydrops (EH) in patients with Meniere's disease (MD) using MRI. The aim of the present study was to optimize a sensitive technique generating strong contrast enhancement from minimum gadolinium-diethylenetriamine pentaacetic acid (Gd-DTPA) while reliably detecting EH in the inner ear, including the apex.

Materials And Methods: All imaging was performed using a 3.

Background: Vestibular drop attacks (VDA), also called Tumarkin otolith crises as a complication of Ménière's disease (MD) were first described in 1936. Nevertheless, a clearer understanding of their prevalence and manifestations is needed.

The Objective: of this review is to determine the frequency, correlates and consequences of VDA in MD.

An endosomal trap is a major barrier in gene therapy. We have designed an endosomolytic peptide based on the leucine zipper sequence and characterized it both structurally and functionally. The results illustrated that leucine zipper endosomolytic peptide (LZEP) exhibited appreciable hemolysis of human red blood cells (hRBCs) at pH 5.

Menière's disease causes paroxysmal rotatory vertigo, due to endolymphatic hydrops, an accumulation of endolymph in the endolymphatic space of the labyrinth. Its major symptoms are attacks of rotatory vertigo lasting minutes to hours, with unilateral hearing loss, tinnitus and aural fullness. As the disease progresses, attacks happen less often, but hearing loss and tinnitus gradually become permanent.
