In the first article submitted to "Journal of Otolaryngology" with the title benign paroxysmal positional vertigo without nystagmus: diagnosis and treatment, there was a literature review, using the following keywords: "dizziness / vertigo, diagnosis / diagnosis, therapeutic / therapeutical approaches. " Scientific publications are included in the period 2001-2009 in Portuguese, English and German. We found nine papers dealt with BPPV without nystagmus, whose diagnosis was based exclusively on clinical history and physical examination. The treatment of BPPV without nystagmus was made by Epley maneuvers, Semont, discharge modified for posterior semicircular canal and Brandt-Daroff exercises. All show that 50% to 97.1% of patients with BPPV without nystagmus, had remission of symptoms, while patients with BPPV nystagmus with remission of symptoms ranged from 76% to 100%. Hence one can conclude that the differences may not be significant, which demonstrates the need for further studies on BPPV without nystagmus. In the second paper, Functional Capacity of Elderly with benign paroxysmal positional vertigo, compared the functional capacity among elderly patients with BPPV and elderly without clinical diagnosis of BPPV and that / or dizziness or vertigo, identifying the physical activities of daily living and instrumental activities of daily living in elderly people in both the Group of Elderly with BPPV (EBPPVG) and Control Group (CG). This is a cross-sectional study, case-control study in Hospital Geral de Goiânia (HGG), with the participation of 14 elderly patients with a diagnosis of BPPV and the Programa de Gerontologia Social / Universidade Aberta à Terceira Idade (UNATI) from the Pontificia Universidade Católica de Goiás (PUC-GO), with the participation of 13 subjects without dizziness or vertigo and / or clinical diagnosis was of BPPV. Functional capacity was assessed by the subscale of the Functional Assessment Questionnaire Brazilian Multidimensional Functional Capacity / Operating Older American Resources and Services Multidimensional Functional Assessment Questionnaire (BOMFAQ/OARS), verifying that the difficulty in performing 15 activities of daily living (ADL), eight physical activities of daily living (AFVD): throw / out of bed, eating, combing hair, walk on the plane, bathing, dressing, going to the bathroom in time and trimming toenails, and seven instrumental activities of living daily living (IADL): climbing stairs (one flight), doctor-on time, walk close to home, shopping, preparing meals, driving out and do house cleaning. Arrived at the following conclusions: a) elderly people with BPPV showed a statistically significant lower functional capacity than subjects without this diagnosis, b) in EBPPVG, the average number of daily activities (physical and instrumental), those with difficulty was 6.53 with a maximum of 11 activities committed while in the CG, the average impairment was 0.86 with a maximum of 4 activities referred with difficulty in performing c) EBPPVG affected performance in 13 activities of daily living, including physical seventh floor in the plan, bathing, dressing, combing hair, going to the bathroom in time, bedtime and getting up from bed or chair and cut nails feet, and 6 which are instrumental, climbing stairs, walking around the house, shopping, preparing meals, driving out and do house cleaning in the comparison between groups, d) Activities that were cited as the most difficult among the elderly were similar in both groups. However, the degree of impairment, characterized in: without commitment (when the elderly did not report any difficulty in any of the 15 evaluated ADL), mild (1 to 3 activities impaired), moderate (4-6 impaired activities) and severe (for seven or more impaired activities) was significantly higher in EBPPVG, where 7 (50%) showed severe impairment in ADL performance. / Dissertação construída na modalidade artigo científico. No primeiro artigo enviado para a Revista Brasileira de Otorrinolaringologia com o título Vertigem Posicional Paroxística Benigna sem nistagmo: diagnóstico e tratamento, realizou-se uma revisão da literatura, utilizando-se os seguintes descritores: vertigem/vertigo, diagnóstico/diagnosis, conduta terapêutica/ therapeutical approaches , palavras e assunto vertigem , nistagmo , VPPB , VPPB sem nitagmo , VPPB subjetiva . As publicações científicas incluídas são do período de 2001 a 2009 nos idiomas português, inglês, espanhol e alemão. Foram encontrados nove artigos que abordam a VPPB sem nistagmo, cujo diagnóstico foi baseado exclusivamente na história clínica e no exame físico. O tratamento da VPPB sem nistagmo foi realizado pelas manobras de Epley, Sémont, liberatória modificada para canal semicircular posterior e exercícios de Brandt-Daroff. Todos evidenciam que de 50% a 97.1% dos pacientes com VPPB sem nistagmo, tiveram remissão dos sintomas, enquanto nos pacientes com VPPB com nistagmo a remissão dos sintomas variou de 76% a 100%. Conclui-se que as diferenças podem não ser significativas, o que demonstra a necessidade de mais estudos sobre a VPPB sem nistagmo. No segundo artigo, com o título Capacidade Funcional de Idosos com Vertigem Posicional Paroxística Benigna, comparou-se a capacidade funcional entre idosos com VPPB e idosos sem diagnóstico clínico referido de VPPB e/ou queixa de tontura ou vertigem, identificando as atividades físicas de vida diária e as atividades instrumentais de vida diária comprometidas nos idosos tanto no Grupo de Idosos com VPPB (GIVPPB) quanto no Grupo Controle (GC). Trata-se de um estudo transversal, analítico, observacional e comparativo, realizado no Hospital Geral de Goiânia (HGG), com a participação de 12 idosos com diagnóstico de VPPB e no Programa de Gerontologia Social/ Universidade Aberta á Terceira Idade (UNATI) da Pontifícia Universidade Católica de Goiás (PUC-GO), com a participação de 13 idosos sem queixa de tontura ou vertigem e/ou diagnóstico clínico referido de VPPB. A capacidade funcional foi avaliada por meio da subescala funcional do Questionário Brasileiro da Avaliação Multidimensional de Capacidade Funcional/Brazilian Older American Resources and Services Multidimensional Functional Assessment Questionaire (BOMFAQ/OARS), verificando a dificuldade referida na realização de 15 atividades de vida diária (AVD), sendo oito atividades físicas de vida diária (AFVD): deitar/levantar da cama, comer, pentear cabelo, andar no plano, tomar banho, vestir-se, ir ao banheiro em tempo e cortar unhas dos pés, e sete atividades instrumentais de vida diária (AIVD): subir escada (um lance), medicar-se na hora, andar perto de casa, fazer compras, preparar refeições, sair de condução e fazer limpeza de casa. Chegou-se às seguintes conclusões: a) idosos com VPPB apresentam uma capacidade funcional estatisticamente significativa menor do que idosos sem este diagnóstico; b) no GIVPPB, o número médio de atividades de vida diária (físicas e instrumentais), referidas com dificuldade foi de 6,53 com o máximo de 11 atividades comprometidas, enquanto no GC, a média de comprometimento foi de 0,86 com o máximo de 4 atividades referidas com dificuldade no desempenho; c) A VPPB prejudicou o desempenho em 13 atividades de vida diária, 7 físicas incluindo andar no plano, tomar banho, vestir-se, pentear-se, ir ao banheiro em tempo, deitar e levantar-se da cama ou cadeira e cortar unhas dos pés; e 6 instrumentais quais sejam, subir escada, andar perto de casa, fazer compras, preparar refeições, sair de condução e fazer limpeza da casa na comparação entre os grupos; d) As atividades que foram referidas como mais difíceis entre os idosos, foram similares em ambos os grupos. Contudo, o grau de comprometimento, caracterizado em: sem comprometimento (quando o idoso não referia dificuldade em nenhuma das 15 AVD avaliadas), leve (de 1 a 3 atividades comprometidas), moderado (de 4 a 6 atividades comprometidas) e severo (de sete ou mais atividades comprometidas) foi significativamente maior no GIVPPB, onde 7(50%) evidenciaram severo comprometimento no desempenho das AVD.

The first article is a systematic review that aimed to investigate the relationship between BPPV and falls (with and without fracture). The review was carried out independently by two researchers, using the combined descriptors in English, Portuguese and Spanish, "vertigo" and "elderly" and "accidental falls"; "benign paroxysmal positional vertigo" and "accidental falls"; in the Virtual Health Library and United States National Library of Medicine (PubMED) databases, being the last search in August 2016. Six scientific papers were selected. The results showed that there were double falls in the elderly with the diagnosis of BPPV and this the relationship increased with advancing age. There was evidence of a decrease in episodes of falls above 60% of the elderly who were treated for BPPV. In elderly people with more than one cause for dizziness, BPPV can not be considered as an independent risk factor for falls. However, in the hospital environment, the relationship between BPPV and falls was not observed when the investigation was performed from the hip fracture. However, when the study included elderly patients hospitalized for various consequences of falls, BPPV could be identified in more than 50% of the patients. It can be concluded that BPPV is associated with falls. The second article, whose primary objective was to evaluate dizziness in the elderly in the primary care for the recognition of BPPV and the secondary one, to analyze the association between dizziness and BPPV with falls. It was a cross-sectional study of 298 diabetic and / or hypertensive elderly individuals enrolled in the Hypertensive and Diabetic Monitoring System of the Basic Family Health Unit of the Madre Germana II neighborhood of Goiânia, Goiás. The evaluation was carried out at the residence of the elderly, including the Mini Mental State Examination, sociodemographic profile, record of self-reported health conditions with emphasis on reporting dizziness and / or vertigo and record of falls in the last 12 months. The elderly who reported dizziness and/or vertigo were revisited for functional otoneurological evaluation for BPPV, using the Dix Hallpike test for the posterior and anterior semicircular canals and the Supine Roll test for the horizontal semicircular canal. The study included 150 elderly individuals with a mean age of 69.7 (+/- 7.36), the majority of them were female. Dizziness was reported by 50 elderly (33.3%). Among the 50 patients who reported dizziness, 19 had objective and subjective BPPV (38.8%). There was association between the complaint of dizziness and falls (p = 0.05), which did not occur with BPPV. The assessment of dizziness and BPPV can be performed in the home of the elderly in primary care. This proactive approach can help prevent falls because dizziness has increased the chances of the elderly falling. Although elderly people who presented objective or subjective BPPV did not increase their chances of falls, the identification of this disease, which has a known, effective and financially inexpensive treatment, may lead to the resolution of this clinical condition. / Tese construída na forma de artigos científicos. O primeiro artigo é uma revisão sistemática que objetivou investigar a relação entre VPPB e quedas (com e sem fratura). A revisão foi realizada de forma independente por duas pesquisadoras, utilizando os descritores combinados em inglês, português e espanhol, “vertigem” and “idoso” and “acidentes por quedas"; “vertigem posicional paroxística benigna” and idoso and acidentes por quedas”; vertigem posicional paroxística benigna” and “acidentes por quedas”, nas bases de dados Biblioteca Virtual em Saúde (BVS), United States National Library of Medicine (PubMED), sendo a última busca em agosto de 2016. Foram selecionados seis artigos. Observou-se diversidade metodológica entre os estudos. Quedas ocorreram o dobro de vezes em idosos com o diagnóstico de VPPB e esta relação aumentou com o avanço da idade. Houve evidência de diminuição de episódios de quedas acima de 60% dos idosos que foram tratados da VPPB. Em idosos com mais de uma causa para a tontura, a VPPB não pode ser considerada como fator de risco independente para quedas. Contudo, no ambiente hospitalar, a relação entre VPPB e quedas não foi observada quando a investigação foi realizada a partir da fratura de quadril. No entanto, quando o estudo incluiu idosos internados por consequências diversas de quedas, a VPPB pôde ser identificada em mais de 50% dos pacientes. Pode-se concluir que a VPPB está associada a quedas. O segundo artigo, teve como objetivos, avaliar a tontura em idosos na atenção primária para o reconhecimento da VPPB e analisar a associação entre tontura e VPPB com quedas. Foi um estudo do tipo transversal sendo estudados 298 idosos diabéticos e/ou hipertensos, cadastrados no Sistema de Acompanhamento de Hipertensos e Diabéticos da Unidade Básica de Saúde da Família do bairro Madre Germana II de Goiânia, Goiás. A avaliação foi realizada na residência dos idosos incluindo o Mini Exame do Estado Mental, perfil sociodemográfico, registro das condições de saúde auto referidas com ênfase no relato de tontura e/ou vertigem e registro de quedas nos últimos 12 meses. Os idosos que referiram tontura e/ou vertigem foram revisitados para avaliação funcional Abstract xvi otoneurológica para VPPB, utilizando o teste de Dix Hallpike para os canais semicirculares posterior e anterior e Supine Roll test para o canal semicircular horizontal. Foram incluídos no estudo 150 idosos com média de idade de 69,7(+/-7,36), a maioria do sexo feminino e 26% referiam queda. Tontura foi referida por 33% dos idosos, dentre os quais, 38,8% apresentaram VPPB. Houve associação entre a queixa de tontura e quedas (p=0,05), o que não ocorreu com a VPPB objetiva ou subjetiva. A avaliação da tontura e VPPB pode ser realizada no domicílio de idosos na atenção primária.

Background: The Mountain Home Veterans Affairs (VA) Medical Center has been diagnosing and treating veterans with benign paroxysmal positional vertigo (BPPV) for almost 2 decades. The clinic protocol includes a 2-week follow-up visit to determine the treatment outcome of the canalith repositioning treatment (CRT). To date, the characteristics of BPPV and treatment efficacy have not been reported in a cohort of veterans with BPPV. Purpose: To determine the prevalence and characteristics of veterans diagnosed with BPPV in a Veterans Affairs Medical Center Audiology Clinic and to examine treatment outcomes. Research Design: Retrospective chart review. Study Sample: A total of 102 veterans who tested positive for BPPV in the Vestibular Clinic at the Mountain Home VA Medical Center from March 2010 to August 2011. Results: In 102 veterans who were diagnosed with BPPV, the posterior semicircular canal was most often involved (75%), motion-provoked vertigo was the most common symptom (84%), and the majority (43%) were diagnosed with BPPV in their sixth decade. The prevalence of BPPV in the Audiology Vestibular Clinic was 15.6%. Forty-one percent of veterans reported a symptom onset within 12 months of treatment for BPPV; however, 36% reported their symptoms began > 36 months prior to treatment. CRT was effective (negative Dix–Hallpike/roll test) in most veterans (86%) following 1 treatment appointment (M = 1.6), but more than half reported incomplete symptom resolution (residual dizziness) at the follow-up appointment. Eighteen percent of veterans experienced a recurrence (M = 1.8 years; SD = 1.7 years). Conclusions: The characteristics and treatment outcomes of BPPV in our veteran cohort was similar to what has been reported in the general population. Future work should focus on improving the timeliness of evaluation and treatment of BPPV and examining the time course and management of residual dizziness.

Dizziness and balance problems are common symptoms at all ages. The aims were; to evaluate rehabilitation, static, dynamic balance and recovery in acute unilateral vestibular loss (AUVL), to evaluate the treatment of benign paroxysmal positional vertigo (BPPV) with assessment of static and dynamic balance and to evaluate the prevalence of dizziness and BPPV in a population of 75-year-olds. Study 1: Twenty-seven patients (51years) with AUVL were included and the recovery was followed regarding vestibular function, dizziness, and sick-leave. The recovery was rapid, with disappearance of spontaneous nystagmus and rapid return to work. Study II: Forty two patents (51 years) with AUVL were included and compared with a reference group. Static and dynamic balance were assessed after six months. Significant instability was found both in static and dynamic balance compared to a reference group. Study III: Seventeen patients (52 years) with severe BPPV (> 3 months) were treated with Semonts´s manouver and/or Brandt-Daroff exercises. The recovery was evaluated by Dix-Hallpike test, subjective dizziness, unsteadiness and balance tests, after 1, 6 and 12 months. Semont´s maneouver resolved dizziness but the long term follow up showed impaired balance. Study IV: A large cohort (675) of elderly was assessed regarding dizziness and BPPV. Side lying test and balance tests were applied. A high prevalence of dizziness (36%) and BPPV (11%) was found. Conclusions: Patients with AUVL and BPPV have despite good symptomatic relief, still impaired static and dynamic balance at long term follow up. BPPV in elderly is common and should be examined since it can be treated.

Evidence-based practice, whose roots emanate from the mid-1960s, aims to provide fair, high-quality, and soundly researched health care with patients' best interests as a priority. Clinical practice guidelines are evidence-based and designed to assist clinicians with sound decision making. Despite the importance of evidence-based practice and the efforts invested into its development and dissemination, its uptake and implementation are poor. The disconnect between evidence-based practice and its translation into clinical practice was previously reported in low-to-middle income countries. This study investigated South African audiologists' and otorhinolaryngologists' (ear, nose and throat specialists') self-reported orientation to evidence-based practice. Second, adherence to evidence-based clinical practice guidelines was assessed with reference to the diagnosis and management of benign paroxysmal positional vertigo, a common vestibular condition for which a firm evidence base supporting treatment exists. A two-part quantitative approach was adopted. Part one surveyed South African audiologists and otorhinolaryngologists with the Evidence-Based Practice Profile Questionnaire and an additional researcher-developed questionnaire pertaining to the diagnosis and management of benign paroxysmal positional vertigo. A total of 130 survey responses were included in this study. Independent sample t-tests, one-way ANOVAs and Fisher's Exact tests were used to analyse the survey data. Part two used a retrospective record review at a tertiary academic hospital in the Western Cape of South Africa. Medical folders of patients diagnosed with benign paroxysmal positional vertigo, between 2010 – 2018 (n = 80), were analysed. The diagnosis and management strategies were recorded and compared against a gold standard evidence based guideline for congruence. Descriptive statistics were used to analyse and understand the data. Survey scores showed a positive association between increased years of experience and healthcare professionals' knowledge (p = .008) and confidence (p = .003) in evidence-based practice. Otorhinolaryngologists might be more knowledgeable than audiologists in evidence-based practice due to their increased training and exposure to evidence-based practice in their specialising years. Findings from the retrospective record review suggested adherence to the clinical practice guidelines in the diagnosis and management of posterior semi circular canal benign paroxysmal positional vertigo. The study outcomes propose that evidence-based clinical practice guidelines developed in the Global North may not be appropriate for the different health contexts that exist in low-to-middle income South Africa (e.g., rural settings). However, the benign paroxysmal positional vertigo clinical practice guidelines were adhered to at a tertiary, academic hospital in Cape Town. The results also support the notion that increased exposure to evidence-based practice reinforces its approach. Outcomes from this study raise implications for the development and dissemination of context-appropriate, evidence-based clinical practice guidelines.

Purpose: The purpose of this study was to evaluate the effectiveness of triaging patients with motion-provoked dizziness into a benign paroxysmal positional vertigo (BPPV) clinic. Method: A retrospective chart review was performed of veterans who were tested and treated for BPPV in a triaged BPPV clinic and veterans who were tested and treated for BPPV in a traditional vestibular clinic. Results: The BPPV triage clinic had a hit rate of 39%. On average, the triaged BPPV clinic reduced patient wait times by 23 days relative to the wait times for the traditional vestibular clinic while also reducing patient costs. Conclusion: Triaging patients with BPPV is one method to improve access to evaluation and treatment and a mechanism for the effective use of clinic time and resources.
