Introduction: Vertigo is defined as the distortion in the sensation of self-movement when a normal movement of the head is made, for its study the TiTrATEapproach is recommended for the general practitioner, which determines the moment of onset, duration, evolution and triggers of vertigo for its study and categorization accurately. Objective: to create a progressive web application (PWA) called TiTrATEapp, Method: Prospective, observational, longitudinal study. Result: creation of a progressive web application (PWA) called TiTrATEapp, based on the TiTrATE algorithm, comparing the calculation time of the application of the algorithm manually and digitally, resulting in the digital application being faster and more efficient. Discussion: Vertigo is a difficult symptom to decipher in the emergency room, due to the subjective description of patients and the wide variety of probable causes, the digitization ofTiTrATE allows to rule out potentially dangerous causes, quickly, accurately. At present there are no studies that measure the effectiveness of mobile applications for the study of vertigo. Conclusion: Mobile applications are an objective tool that helps health professionals diagnose and make clinical decisions in a practical way based on scientific evidence, the digitalization of TiTrATE allows resident doctors to make an accurate diagnosis quickly and guide the patient's referral to the correct specialty and resource efficiency.

RESUMO

OBJECTIVE: Due the lack of data on the treatment of Vascular Vertigo and Dizziness, this study aimed to report how we managed and treated those outpatients according to the recently introduced American Heart Association and Stroke Association guidelines. METHODS: We conducted a longitudinal case series from May 2022 to February 2023. We included patients who met the Bárány Society's Vascular Vertigo and Dizziness classification and were eligible for therapy in accordance with the American Heart Association and Stroke Association guidelines, featuring aspects of the stroke group and transient attack group. RESULTS: Overall, 41 patients (51.2% female; median age 72 years) were enrolled; 10 (24.3%) had ischemic strokes, 30 (73.1%) had transient ischemic attack, and 1 (2.4%) had a probable isolated labyrinthine infarction. The patients received dual antiplatelet (48.7%), single antiplatelet therapy (48.7%), and anticoagulant therapy (2.4%). No new crises occurred in 95.2% of the patients, and the transient ischemic attack group showed a significant decrease in discomfort from imbalance on the visual analog scale. CONCLUSIONS: Antiplatelets and anticoagulants are safe and effective in treating Vascular Vertigo and Dizziness as they prevent new ischemic events and increase the flow of the posterior circulation, reducing vertigo/dizziness attacks and imbalance complaints.

RESUMO

OBJECTIVE: Dizziness or vertigo in older population frequently presents in clinical settings, yet its etiology remains elusive. The objective of this study was to delineate global trends and identify frontiers in research concerning dizziness or vertigo among older population. METHODS: We searched the research literature published from 2003 to 2022 on older population with dizziness or vertigo using two databases from the Web of Science Core Collection. A bibliometric and visualization analysis was conducted. Bibliometric tools facilitated co-authorship, co-citation, and keyword co-occurrence analyses, encompassing countries or regions, institutions, authors, journals, and references. RESULTS: The analysis included 1322 publications authored by 6524 individuals from 2244 institutions across 67 countries or regions, spanning 92 subject categories. A steady increase in publications was noted from 2003 to 2022. The University of Munich, Harvard University, and the University of California System emerged as leading institutions with the highest publication outputs. The United States, Germany, and China were predominant in publication counts. Eva Grill was identified as the most prolific author. Otology & Neurotology and Geriatrics & Gerontology emerged as the most prolific journal and subject category, respectively. The most prevalent keywords were "dizziness", "vertigo", "falls", and "geriatric", with "management", "gait", and "association" recognized as the principal research hotspots. CONCLUSION: This study provides a systematic analysis of global scientific research on older population dizziness/vertigo, revealing significant advancements in understanding over the past two decades. Management, gait, and association have emerged as the primary research focuses on recent years. These findings offer valuable insights for directing current research efforts to capture prevailing trends and explore new frontiers in this field.

RESUMO

OBJECTIVE: To find out if motion sickness susceptibility (MSS) of vestibular migraine (VM) patients and migraine only (MO) patients can be reliably detected with a single simple question: "Can you read while travelling in a car without getting motion sick?". METHOD: Ninety-two definite VM and 58 MO patients and 74 healthy control (HC) subjects were asked about their MSS and about being able to read while riding in a car without becoming motion sick. A Motion Sickness Susceptibility Questionnaire (MSSQ-Short) including childhood (MSA), adulthood (MSB) and total (MST) parts was also administered to all participants. ROC curves of MSSQ-Short were prepared for "not being able to read in a car" as the gold standard. RESULTS: Mean MSA scores were significantly higher in both VM and MO patients than in HCs (p < 0.001), but their scores were not significantly different (p = 0.171). Mean MSB and MST scores were significantly higher in VM than in MO patients (p < 0.001) and both VM and MO patients had significantly higher scores than HCs (p < 0.001). MSA scores were significantly higher than MSB scores in MO patients (p < 0.001). All sections of the questionnaire were associated with high area-under-curve values for MSS detected by the question about being able to read in a car without becoming motion sick. CONCLUSION: We propose that all migraine patients could have the same level of MSS in childhood but MO patients are able to compensate over years, but VM patients are not. A quick way to determine MSS is to ask about the ability to read without becoming motion sickness while riding a car.

RESUMO

BACKGROUND Superior semicircular canal dehiscence is an inner-ear pathology which presents with vertigo, disequilibrium, and hearing loss. Although the exact etiology of superior semicircular canal dehiscence is unknown, it is thought that an increase in middle-ear pressure disrupts a thin overlying temporal bone. Superior semicircular canal dehiscence is frequently seen in association with dehiscence of the tegmen tympani, which overlies the middle ear. Here, we present a case report of a 52-year-old Puerto Rican man with vertigo, dizziness, vomiting, and mild hearing loss associated with superior semicircular canal and tegmen tympani dehiscence after performing improper scuba diving techniques. CASE REPORT A 52-year-old Puerto Rican man presented to the emergency department with vertigo, dizziness, vomiting, and mild hearing loss in the right ear. The symptoms began shortly after scuba diving with inadequate decompression techniques on ascent. He was treated with recompression therapy with mild but incomplete improvement in symptoms. Bilateral temporal magnetic resonance imaging was suggestive of segmental dehiscence of the right superior semicircular canal and tegmen tympani. High-resolution computed tomography of the temporal bone confirmed right superior semicircular canal and tegmen tympani dehiscence with an intact left inner ear. CONCLUSIONS The increased inner-ear pressure that occurs during scuba diving can lead to dehiscence of the superior semicircular canal and tegmen tympani, causing vertigo and hearing loss. Performance of improper diving techniques can further increase the risk of dehiscence. Therefore, appropriate radiologic evaluation of the inner ear should be performed in such patients.

RESUMO

OBJECTIVE: This study aimed to determine the prevalence of dizziness and its associated factors in patients with COM at two otologic referral centres in a middle-income country. DESIGN: Cross-sectional study. Adults with and without COM diagnosis from two otology-referral centres in Bogotá (Colombia) were included. Dizziness and quality of life were assessed using the "Chronic Suppurative Otitis Media Questionnaire-12" (COMQ-12), and sociodemographic questionnaires were applied. Otoscopic evaluation and audiometric data were collected. STUDY SAMPLE: A total of 231 adults. RESULTS: Of the 231 participants, up to 64.5% (n = 149) reported at least mild inconvenience due to dizziness. Factors associated with dizziness included female sex (aPR: 1.23; 95% CI: 1.04-1.46), chronic suppurative otitis media (aPR: 3.02; 95% CI: 1.21-7.52), and severe tinnitus (aPR: 1.75; 95% CI: 1.24-2.48). An interaction was found between socioeconomic status and educational level, with more frequent reports of dizziness in the middle/high economic status and secondary education (aPR: 3.09; 95% CI: 0.52-18.55; p < 0.001). Differences of 14 points in symptom severity and 18.5 points in the total score of the COMQ-12 were found between the groups with dizziness and without dizziness. CONCLUSIONS: Dizziness was frequent in patients with COM and was associated with severe tinnitus and quality of life deterioration.

RESUMO

PURPOSE: To determine the internal consistency and reliability of the "Questionário de Impacto Emocional da Vertigem (CIEV)" and to validate the instrument with respect to the Dizziness Handicap Inventory (DHI) in a sample of individuals with balance disorders. METHODS: 38 subjects participated in the study, males and females, aged from 23 to 85 years, who presented dizziness, vertigo, and/or falls complaints and attended to the Vestibular Disorders clinic at the University Hospital. Individuals with hearing complaints and/or tinnitus unrelated to dizziness, previous psychiatric comorbidities, and/or cognitive impairments were excluded. We performed an anamnesis and collected complementary data from the medical records. After that, the self-perception questionnaires, DHI, and CIEV, were applied. Statistical analysis was performed in which the Cronbach's alpha verified the internal consistency of the CIEV. Reliability and validity of the CIEV related to the DHI were calculated using Intraclass Correlation Index (ICC) and Pearson's correlation test, respectively. RESULTS: There was a statistically significant correlation between the scores obtained, for both reliability and validation analysis (p<0.001). The mean ICC showed a moderate correlation between the total scores (0.695) and a strong correlation with the physical, emotional, and functional DHI domains (0.706 to 0.869), being the emotional aspect the highest degree (0.869). Pearson's correlation showed strong correlation between the total scores (r=0.820) and varied from moderate to strong, with strongest correlations to the DHI emotional domain (r=0.788). CONCLUSION: The outcomes illustrate important contribution to validation parameters to consider clinical use of the CIEV in the Brazilian population, aiming to identify emotional aspects in patients with balance disorders.

OBJETIVO: Determinar a consistência interna e confiabilidade do "Questionário de Impacto Emocional da Vertigem-CIEV" e validar o instrumento em relação ao Dizziness Handicap Inventory (DHI), em uma amostra de pacientes com distúrbio do equilíbrio corporal. MÉTODO: Participaram 38 sujeitos, idades entre 23 e 85 anos, ambos os sexos, com queixas relacionadas à tontura, desequilíbrios e/ou quedas, atendidos em um ambulatório de Otoneurologia do Hospital Universitário. Foram excluídos sujeitos com queixas auditivas e/ou zumbido sem tontura associada, comorbidades psiquiátricas prévias e/ou comprometimento cognitivo que impedisse a compreensão dos questionários. Foi realizada anamnese, levantamento de prontuário para caracterização da amostra e aplicados os questionários de autopercepção, DHI e CIEV. O alfa de Cronbach verificou a consistência interna do CIEV e a confiabilidade e validade do CIEV em relação ao DHI foram calculadas pelo Índice de Correlação intraclasse (ICC) e teste de Correlação de Pearson, respectivamente. RESULTADOS: Houve correlação estatisticamente significante entre os escores obtidos, tanto à análise de confiabilidade quanto de validação (p<0,001). O ICC médio demonstrou moderada correlação para o escore total (0,695) e forte correlação com os domínios físico, emocional e funcional do DHI (0,706 a 0,869) sendo o maior grau para o domínio emocional (0,869). A Correlação de Pearson demonstrou grau forte para o escore total (r=0,820) e variação de moderado a forte para os domínios, com melhor resultado também para o domínio emocional do DHI (r=0,788). CONCLUSÃO: Os achados representam parâmetros importantes de contribuição para a validação do CIEV para uso clínico na população brasileira, direcionado para a identificação de aspectos emocionais em pacientes com distúrbios do equilíbrio corporal.

RESUMO

Introducción: El mareo postural perceptual persistente (MPPP) es una de las causas más frecuentes de vértigo crónico. Si bien, los pacientes con MPPP tienen alteraciones de la percepción espacial, se desconoce si presentan alteraciones en el miedo a las alturas. Para no exponer a pacientes con MPPP a ambientes reales con altura, nos propusimos utilizar la realidad virtual para estudiar el miedo a las alturas. Objetivo: Cuantificar el miedo a las alturas en pacientes con MPPP y controles mediante ambientes simulados con realidad virtual. Material y Método: Estudio transversal, prospectivo de casos y controles pareados por edad y sexo. Se reclutaron pacientes con MPPP del Servicio de Otorrinolaringología del Hospital Clínico de la Universidad de Chile entre los años 2020 y 2021. Se midió presencia subjetiva de miedo y taquicardia. Los escenarios se desarrollaron con el programa Blender 2.8 y Oculus Link para equipo Oculus Quest. Se utilizaron cinco escenarios a diferentes alturas (pisos 1, 3, 6, 12, 19). Resultados: Se reclutaron 20 sujetos (12 mujeres, 47 años en promedio), incluyendo 10 pacientes con MPPP y 10 controles sin síntomas vestibulares. Ningún sujeto del grupo control presentó miedo en los escenarios presentados, mientras que siete pacientes del grupo MPPP tuvieron miedo subjetivo a una altura menor a 40 metros virtuales (Fischer, p < 0,05). Conclusión: Los pacientes con MPPP presentan, con mayor frecuencia, miedo subjetivo a las alturas que los controles, pero se requiere de nuevos estudios para determinar si este miedo es específico de MPPP, o es general a otras causas de vértigo crónico.

Introduction: Persistent Postural Perceptual Dizziness (PPPD) is one of the most common causes of chronic vertigo. While patients with PPPD have spatial perception alterations, it is unknown whether they present alterations in fear of heights. To avoid exposing patients with PPPD to high places, we aimed to use virtual reality to quantify fear of heights. Aim: To quantify fear of heights in patients with PPPD and controls using simulated environments with virtual reality. Material and Method: A prospective cross-sectional study of age- and sex-matched case-control pairs. PPPD patients were recruited from the Otolaryngology Service of the Clinical Hospital of the University of Chile between 2020 and 2021. Presence of subjective fear and tachycardia were measured. The scenarios were developed using Blender 2.8 and Oculus Link for the Oculus Quest. Five scenarios at different heights (floors 1, 3, 6, 12, 19) were used. Results: Twenty subjects were recruited (12 women, average age of 47 years), including 10 PPPD patients and 10 controls without vestibular symptoms. None of the control group subjects presented fear in the presented scenarios, while seven patients in the PPPD group had subjective fear at a height lower than virtual 40 meters (Fischer, p < 0.05). Conclusion: Patients with PPPD present a greater proportion of subjective fear to heights than controls, but further studies are required to determine if this fear is specific to PPPD or is general to other causes of chronic vertigo.
