Prognosis of asymptomatic endolymphatic hydrops in healthy volunteers: A five-year cohort study.

Background: This study aimed to clarify the prognosis of asymptomatic endolymphatic hydrops (EH) in healthy volunteers via five-year follow-ups with inner ear magnetic resonance imaging (MRI).

Methods: Inner ear MRI was performed on 115 participants recruited as controls in a previous study on Meniere's disease. The endolymphatic space was visualized using Naganawa's method of contrast-enhanced MRI with intravenous gadolinium injection and evaluated using Nakashima's method of 2D imaging analysis.

Determining factors for dexmedetomidine sedation in endoscopic submucosal dissection for early-stage gastric cancer.

Background And Aim: Although no specific sedation recommendations exist in early-stage gastric cancer (ESGC) for endoscopic submucosal dissection (ESD), dexmedetomidine (DEX) is useful along with benzodiazepines and analgesics. Furthermore, DEX is used for endoscopic treatment requiring lengthy sedation. However, it is unclear which patients should be administered DEX.

Eco-friendly strategy for CO enrichment performance in commercial greenhouses based on the CO spatial distribution and photosynthesis.

CO enrichment is an essential environmental control technology due to its significantly enhancing effect on crop production capacity. Despite being a key energy consumer in protected agriculture (i.e.

Temporal Bone Histopathology of Undiagnosed Dizziness in the Elderly.

Introduction: Dizziness is a common disease. However, approximately 10-40% of patients were diagnosed unknown dizziness even though general, neurological, and otological examinations were performed. The aim of this otopathological study was to investigate the histopathology of the peripheral vestibular system of patients who suffered from undiagnosed dizziness.

Hypoglossal Nerve Palsy Following COVID-19 Vaccination in a Young Adult Complicated by Various Medicines.

Mononeuritis multiplex is a rare form of cerebral nerve palsy caused by various factors. Coronavirus disease 2019 (COVID-19) vaccination could be an etiology of mononeuritis multiplex, which can affect various nerves. Post-COVID-19 and vaccination-related neurological impairments involve cranial nerves such as the facial, trigeminal, and vagal nerves.

Refractory Immunoglobulin A (IgA) Vasculitis in an Elderly Patient: A Case Report.

Immunoglobulin A (IgA) vasculitis is small-vessel arteritis triggered by autoimmunity and allergies. IgA vasculitis among elderly patients is rare, and there is a lack of evidence regarding the choice of medicine and treatment duration. The main treatment for IgA vasculitis is steroids which can be cured with a small dose of prednisolone without immunosuppressants.

Giant Cell Arteritis Mimicking Polymyalgia Rheumatica: A Challenging Diagnosis.

Giant cell arteritis (GCA) is an autoimmune disease that causes inflammation of the middle and large arteries. Rural areas have many older patients with various symptoms, so large-vessel-type GCA should be managed effectively. Older patients tend to show vague symptoms that cannot be adequately diagnosed and observed.

Coexistence of Pancytopenia and Myositis After Developing COVID-19.

COVID-19 causes not only acute but also subacute medical conditions during the clinical course. COVID-19 causes severe inflammatory conditions; therefore, patients may develop long-term complications. Among patients with acute COVID-19, some patients can experience persistent symptoms, such as fatigue, joint pain, and smell and taste abnormalities, known as the long COVID-19 syndrome.

Behavioral and Immunohistochemical Evidence for Suppressive Effects of Goshajinkigan on Salicylate-Induced Tinnitus in Rats.

Many people are affected by tinnitus, a sensation of ringing in the ear despite the absence of external sound. Goshajinkigan (GJG) is one of the formulations of Japanese traditional herbal medicine and is prescribed for the palliative treatment of patients with tinnitus. Although GJG is clinically effective in these patients, its behavioral effects and the underlying neuroanatomical substrate have not been modeled in animals.

Endolymphatic Sac Drainage Surgery and Plasma Stress Hormone Vasopressin Levels in Meniere's Disease.

Meniere's disease is a common inner ear disorder accompanied by vertigo attacks and fluctuating hearing loss that some believe is due to a stressful lifestyle. To elucidate the scientific relationship in neuro-endocrinology between Meniere's disease and stress, we examined the surgical results of endolymphatic sac drainage surgery and changes in stress-induced plasma arginine-vasopressin levels. We enrolled 100 intractable Meniere's patients and examined surgical results and plasma vasopressin levels.

Speech recognition scores in bilateral and unilateral atretic ears.

Objective: Congenital aural atresia causes severe conductive hearing loss disturbing auditory development. The differences in speech recognition were investigated between bilateral and unilateral aural atresia.

Design: The maximum speech recognition scores (SRSs) were compared between patients with bilateral and unilateral aural atresia.

Long-term (16-26 years) follow-up outcome of steroid therapy in refractory autoimmune sensorineural hearing loss.

Autoimmune sensorineural hearing loss (ASHL) is a rare disease of uncertain etiology, with no established treatment strategy. The duration of morbidity is increased in refractory cases; and therefore, the preservation of hearing and the prevention of adverse effects with steroid therapy are serious long term issues to consider. Long-term follow up of patients treated for ASHL was performed retrospectively in order to elucidate the pathogenesis of ASHL, evaluate the consequences of steroid therapy, and determine a promising treatment course.

Cooperation of chloroplast ascorbate peroxidases and proton gradient regulation 5 is critical for protecting Arabidopsis plants from photo-oxidative stress.

High-light (HL) stress enhances the production of H O from the photosynthetic electron transport chain in chloroplasts, potentially causing photo-oxidative damage. Although stromal and thylakoid membrane-bound ascorbate peroxidases (sAPX and tAPX, respectively) are major H O -scavenging enzymes in chloroplasts, their knockout mutants do not exhibit a visible phenotype under HL stress. Trans-thylakoid proton gradient (∆pH)-dependent mechanisms exist for controlling H O production from photosynthesis, such as thermal dissipation of light energy and downregulation of electron transfer between photosystems II and I, and these may compensate for the lack of APXs.

Otopathology in Kleefstra Syndrome: A Case Report.

Kleefstra syndrome is a rare neurogenetic disorder caused by a subtelomeric 9q34.3 deletion or by an intragenic mutation of the euchromatin histone methyl transferase 1 gene (EHMT1). Approximately 20% to 30% of individuals have hearing loss.

Sensorineural Hearing Loss in Leukemia: A Case Report Showing Intravascular Coagulation in the Cochlea and Vestibular Labyrinth.

Introduction: Sensorineural hearing loss frequently has been described in patients with leukemia, and in fact, hearing loss may be the presenting symptom of this disease. However, the pathogenesis of sensorineural hearing loss in leukemia is not well understood.

Objective: To describe the temporal bone histopathology in 1 patient with leukemia and sensorineural hearing loss.

Spin-momentum locked spin manipulation in a two-dimensional Rashba system.

Spin-momentum locking, which constrains spin orientation perpendicular to electron momentum, is attracting considerable interest for exploring various spin functionalities in semiconductors and topological materials. Efficient spin generation and spin detection have been demonstrated using the induced helical spin texture. Nevertheless, spin manipulation by spin-momentum locking remains a missing piece because, once bias voltage is applied to induce the current flow, the spin orientation must be locked by the electron momentum direction, thereby rendering spin phase control difficult.
