A New Method for Gain Calculation in Quantified Visuo-vestibular Interaction Test.

Objective: To develop a new method to quantify visually-enhanced vestibulo-ocular reflex (VVOR) gain, in patients with vestibular function loss, that is mathematically suitable given the nature of the test, and determine the reliability of the method by comparing results with those of the gold standard, the video head impulse test (vHIT).

Materials And Methods: We developed a new method for VVOR gain quantification and conducted a cross-sectional study in patients diagnosed with vestibular function loss and controls, all participants undergoing both a VVOR test and a vHIT. We measured VVOR gain with three different methods: area under the curve (AUC), slope regression, and a Fourier method (VVOR , VVOR , and VVOR , respectively); and compared these gain values with vHIT gain calculated using the AUC method.

Translation into Spanish and validation of the Tinnitus Functional Index (TFI).

Objective: The objectives of this study were to translate into Spanish, cross-culturally adapt and validate the TFI.

Materials And Methods: The TFI questionnaire translated into Spanish (Sp-TFI) and cross-culturally adapted following the published guidelines on cross-cultural adaptation of health questionnaires was evaluated using two indicators. Its internal consistency was assessed with Cronbach's α considering the Tinnitus Handicap Inventory (THI) as the gold standard.

Synchronized refixation saccades in enhanced VVOR test. A new application for PR score.

Objective: Main objectives for this study were to develop a quantification method to obtain a Perez-Rey (PR) score adapted to the VVOR test and to evaluate the correlation of the PR score obtained with quantified VVOR with the PR score of the vHIT test.

Methods: A new PR score calculation method for quantified VVOR test was developed using the MATLAB computational software based on saccadic response time latency variability between each head oscillation cycle of the VVOR test. Retrospective correlation between PR scores in VVOR and vHIT tests, performed in the same vHIT testing session for patients with vestibular neuritis and vestibular neurectomy, was performed to correlate new PR (VVOR) score with the classic PR (vHIT) score.

Enhanced Eye Velocity With Backup Saccades in vHIT Tests of a Menière Disease Patient: A Case Report.

Reduced eye velocity and overt or covert compensatory saccades during horizontal head impulse testing are the signs of reduced vestibular function. However, here we report the unusual case of a patient who had enhanced eye velocity during horizontal head impulses followed by a corrective saccade. We term this saccade a "backup saccade" because it acts to compensate for the gaze position error caused by the enhanced velocity (and enhanced VOR gain) and acts to return gaze directly to the fixation target as shown by eye position records.

Complications after Functional Neck Dissection in Head and Neck Cancer Patients: An Observational, Retrospective, Single-Centre Study.

Introduction: Functional neck dissection (FND) represents a surgical procedure usually associated with less morbidity.

Methods: An observational, retrospective, analysis of patients diagnosed with any type of head and neck malignancy was designed to summarize and report the incidence of postoperative complications in patients undergoing FND including just those levels described for selective neck dissections in a tertiary university hospital between June 2016 and June 2019.

Results: 131 patients met the inclusion criteria.

Predictive factors for simultaneous distant metastasis in head and neck cancer patients during the diagnostic work-up.

Introduction: The incidence of distant metastasis (DM) in patients affected by head and neck squamous cell carcinoma (HNSCC) is relatively low, and multiple risk factors were described for the development of distant metastasis.

Materials And Methods: Retrospective study of patients diagnosed with a HNSCC between July 2016 and July 2020 in a tertiary university hospital.

Results: Five-Hundred and sixty-nine patients meet inclusion criteria.

Subjective evaluation of smell and taste dysfunction in patients with mild COVID-19 in Spain.

Background: Has been described the loss of smell and taste as onset symptoms in SARS-CoV-2. The objective of this study was to investigate the prevalence in Spain.

Methods: Prospective study of COVID-19 confirmed patients through RT-PCR in Spain.

Translation and Validation of the Facial Clinimetric Evaluation Scale to Spanish.

Objective: Peripheral facial palsy is a disabling condition; thus, assessing its impact on quality of life is one of the greatest challenges within this discipline. The Facial Clinimetric Evaluation (FaCE) Scale has been validated for this purpose. The aim of this study is to translate and validate the Spanish version of the FaCE Scale.

Subjective evaluation of smell and taste dysfunction in patients with mild COVID-19 in Spain.

Background: Has been described the loss of smell and taste as onset symptoms in SARS-CoV-2. The objective of this study was to investigate the prevalence in Spain.

Methods: Prospective study of COVID-19 confirmed patients through RT-PCR in Spain.

Transoral Carbon Dioxide Microsurgery of the Larynx as a Day-Case Outpatient Procedure: An Observational, Retrospective, Single-Center Study.

Introduction: Despite good results of transoral laser CO microsurgery (COTOLMS) of the larynx, a lack of data related to the safety of this technique as a day-case procedure across the literature is evident.

Materials And Methods: An observational, retrospective, non-randomized study.

Results: One hundred four (62.

Ethyl alcohol threshold test: a fast, reliable and affordable olfactory Assessment tool for COVID-19 patients.

Objective: COVID-19 patients may present mild symptoms. The identification of paucisymptomatic patients is paramount in order to interrupt the transmission chain of the virus. Olfactory loss could be one of those early symptoms which might help in the diagnosis of COVID-19 patients.

Effects of parameters of video head impulse testing on visually enhanced vestibulo-ocular reflex and vestibulo-ocular reflex suppression.

Objective: To investigate the main effects of some testing and analysis variables on clinically quantified visually enhanced vestibulo-ocular reflex (VVOR) and vestibulo-ocular reflex suppression (VORS) results using video head impulse test.

Methods: This prospective observational clinical study included 19 healthy participants who underwent the VVOR and VORS tests. The effect of demographic variables, head oscillation frequency, rotation direction, visual acuity and analysis time window width and location of the recorded tests on the quantified results of both VVOR and VORS were evaluated.

Phone Speech Recognition Improvement in Noisy Environment: Use of a Bluetooth Accessory.

Objective: To evaluate speech understanding in noise and patient satisfaction using the new Cochlear Wireless Phone Clip device.

Material And Methods: Twenty-nine experienced cochlear implant (CI) users (>6 months usage) were situated in a soundproof room where a 65 dB SPL Spanish cocktail noise was generated continuously from 4 loudspeakers. Lists of disyllabic words were presented through the clinic landline telephone to the patients.

Interaction of Sex and Diabetes on Outcome After Ischemic Stroke.

Background: The relationship between ischemic stroke (IS), diabetes mellitus (DM), and sex is intriguing. The aim of this study was to assess the effect modification of sex in the association between DM and short- and long-term disability and mortality in first-ever IS patients.

Methods: In a retrospective, observational, hospital-based study of a prospective series including first-ever IS patients from January 2006 until July 2011, differences in 3-month and 5-year mortality, and disability between diabetic and non-diabetic patients [modified Rankin Scale (mRS) from 3 to 5] were analyzed by sex.
