Unravelling large-scale patterns and drivers of biodiversity in dry rivers.

More than half of the world's rivers dry up periodically, but our understanding of the biological communities in dry riverbeds remains limited. Specifically, the roles of dispersal, environmental filtering and biotic interactions in driving biodiversity in dry rivers are poorly understood. Here, we conduct a large-scale coordinated survey of patterns and drivers of biodiversity in dry riverbeds.

Comparison between Classical- and Rotational-Mechanical-Chair-Assisted Maneuvers in a Population of Patients with Benign Paroxysmal Positional Vertigo.

: Benign paroxysmal positional vertigo (BPPV) stands as the most common cause of peripheral vertigo. Its treatment with repositioning maneuvers on an examination table is highly effective. However, patients with back or neck problems, paraplegia, or other conditions face challenges with these maneuvers, potentially experiencing longer healing times and creating additional difficulties for physicians diagnosing and treating BPPV in everyday practice.

Superior semicircular canal dehiscence in relation with the superior petrosal sinus: our experience, surgical management and systematic review of literature.

Purpose: Most of Superior Semicircular Canal Dehiscence (SSCD) are located in the apical region of the SSC. However, in a small number of cases, it may be situated in the medial wall, causing the SSC to contact with the superior petrosal sinus (SPS). The aim of this study is to describe four patients with SSCD involving the superior petrosal sinus (SSCD-SPS) and to perform a review of the literature.

ChatGPT as an information tool in rhinology. Can we trust each other today?

Purpose: ChatGPT (Chat-Generative Pre-trained Transformer) has proven to be a powerful information tool on various topics, including healthcare. This system is based on information obtained on the Internet, but this information is not always reliable. Currently, few studies analyze the validity of these responses in rhinology.

Bow and Lean Test for Rare Variants of Vertical Semicircular Canal BPPV.

Objective: The objective of this study was to assess the clinical significance of the Bow and Lean Test (BLT) for the diagnosis of different variants of vertical canal Benign Paroxysmal Positional Vertigo (BPPV). BLT is commonly used for diagnoses of lateral semicircular canal (LSC) BPPV. However, vertical nystagmus in the BLT may indicate the presence of other variants such as PSC-BPPV.

Audiovestibular Manifestations in Patients with Primary Raynaud's Phenomenon and Raynaud's Phenomenon Secondary to Systemic Sclerosis.

Objectives: To address the prevalence of audiovestibular disorders in patients with primary Raynaud's Phenomenon (RP). A series of patients with primary RP and secondary RP in the context of systemic sclerosis (SSc) were compared with healthy controls.

Methods: A prospective multicenter observational cross-sectional study was conducted in several Otolaryngology and Rheumatology Divisions of tertiary referral hospitals, recruiting 57 patients with RP and 57 age- and gender-matched controls.

Long-Term Evolution of Vestibular Compensation, Postural Control, and Perceived Disability in a Population of Patients with Vestibular Neuritis.

Objectives: The aim was to analyze and compare the compensatory process, vestibular dysfunction, postural control, and perceived disability in a population of patients with vestibular neuritis (VN).

Material And Methods: This is a prospective and longitudinal study of 67 patients diagnosed with VN. Inclusion criteria were sudden onset of vertigo, unidirectional spontaneous horizontal nystagmus, and impairment in vestibular test.

Low-Dose Intratympanic Gentamicin for Unilateral Ménière's Disease: Accuracy of Early Vestibulo-Ocular Reflex Gain Reduction in Predicting Long-Term Clinical Outcome.

Background: The number of intratympanic gentamicin (ITG) injections needed to achieve vertigo control in patients with intractable Ménière's disease (MD) may vary from a single dose to several instillations. Changes in different vestibular test results have been used to define an endpoint of treatment, including the decrease of the vestibulo-ocular reflex (VOR) gain elicited by the head-impulse test.

Objective: To assess the accuracy of the VOR gain reduction after horizontal canal stimulation, as measured with the video head-impulse test (vHIT) 1 month after the first intratympanic injection, in predicting the need for one or more instillations to control vertigo spells in the long term.

Clinical Subtypes and vHIT Parameters in a Population With Bilateral Vestibulopathy.

To evaluate the different peripheral, neurological, genetic, and systemic etiologies of bilateral vestibulopathy (BVP) and the value of vHIT in the diagnostic process. A retrospective case review was performed on 176 patients diagnosed with BVP in a tertiary referral center, between 2010 and 2020. Inclusion criteria comprised imbalance and/or oscillopsia during locomotion and horizontal angular VOR gain on both sides <0.

Long-term follow-up of olfactory and gustatory dysfunction in COVID-19: 6 months case-control study of health workers.

Purpose: The study aimed to determine the incidence and long-term evolution of COVID-related olfactory (OD) and gustatory (GD) dysfunction, the recovery timeline, and the association with other symptoms. The secondary objective was to identify the predictive clinical factors for the evolution of these symptoms.

Methods: A prospective case-control study was conducted from March 15 to October 15, 2020, in health workers with COVID-19 related symptoms in a tertiary care hospital.

Vibration-induced nystagmus and head impulse test screening for vestibular schwannoma.

Level Of Evidence: II-2.

Background: Vestibular schwannomas are benign tumors of the eight cranial nerve that may cause asymmetric sensorineural hearing loss (ASHL) and vestibular dysfunction.

Objective: The aim of this study was to assess the role of the video head impulse test (vHIT) and vibration-induced nystagmus (VIN) test in diagnosing vestibular schwannoma in a population of patients with Asymmetric sensorineural hearing loss.

Prospective Study in 355 Patients With Suspected COVID-19 Infection: Value of Cough, Subjective Hyposmia, and Hypogeusia.

Objective: To evaluate the incidence of certain symptoms in a population of health workers exposed to coronavirus disease 2019 patients.

Study Design: Case-control study.

Methods: The study was conducted at a tertiary care hospital from March 1 to April 7, 2020.

Safety and Prognosis in Percutaneous vs Surgical Tracheostomy in 27 Patients With COVID-19.

During the SARS-CoV-2 pandemic, patients in intensive care units who are undergoing long-term intubation may require tracheostomy. There is controversy about indication and health care professionals' safety regarding the conventional or percutaneous technique. We performed a prospective analysis of a series of 27 consecutive patients with COVID-19 comparing both tracheostomy techniques, safety, and prognosis clinical markers.

Relevance of Artifact Removal and Number of Stimuli for Video Head Impulse Test Examination.

Objective: To evaluate the effect of artifacts on the impulse and response recordings with the video head impulse test (VHIT) and determine how many stimuli are necessary for obtaining acceptably efficient measurements.

Corrigendum: Clinical Features of Headache in Patients With Diagnosis of Definite Vestibular Migraine: The VM-Phenotypes Projects.

[This corrects the article DOI: 10.3389/fneur.2018.

Oscillopsia in Bilateral Vestibular Hypofunction: Not Only Gain But Saccades Too.

Objectives: Oscillopsia is a disabling condition for patients with bilateral vestibular hypofunction (BVH). When the vestibulo-ocular reflex is bilaterally impaired, its ability to compensate for rapid head movements must be supported by refixation saccades. The objective of this study is to assess the relationship between saccadic strategies and perceived oscillopsia.

Differential Proinflammatory Signature in Vestibular Migraine and Meniere Disease.

Vestibular Migraine (VM) and Meniere's Disease (MD) are episodic vestibular syndromes defined by a set of associated symptoms such as tinnitus, hearing loss or migraine features during the attacks. Both conditions may show symptom overlap and there is no biological marker to distinguish them. Two subgroups of MD patients have been reported, according to their IL-1β profile.
