Prosper Menière: the man who located vertigo in the inner ear.

Since the Greek Aellus Galenum (129 AD - c.200/c.216), vertigo was considered a problem attributed to a cerebral disorder, diagnosed as the manifestation of apoplectiform cerebral congestion. In the mid-19th century, the Frenchman Prosper Menière changed this concept by placing the origin of this symptom in the inner ear. The main objective of this historical note is to highlight who Menière was, his work, and some aspects of the disease that bears his name.

RESUMO Desde o grego Aellus Galenum (129 d.C. - c.200/c.216), a vertigem era considerada um problema atribuído a um distúrbio cerebral, diagnosticado como a manifestação de uma 'congestão cerebral apoplectiforme'. Em meados do século 19, o francês Prosper Menière mudou esse conceito, colocando a origem desse sintoma na orelha interna. O principal objetivo desta nota histórica é ressaltar quem foi Menière, seu trabalho e alguns aspectos da doença que leva seu nome.

The minimal caloric test asymmetric response in vertigo-free migraine patients.

Vertigo symptoms and subclinical vestibular dysfunctions may occur in migraine. The Minimal Caloric Test (MCT), an easy-to-perform, convenient and yet informative procedure was used to test the vestibular function in 30 vertigo-free migraine patients outside attacks and 30 paired controls. Although not statistically significant, a right-to-left nystagmus duration asymmetry greater than 25% was present in both groups. This difference was greater in the patients group, suggesting the presence of subclinical vestibular imbalance in migraine.

RESUMO Vertigem e alterações vestibulares subclínicas têm sido identificadas na enxaqueca. O teste calórico mínimo é simples de realizar, informativo e conveniente. Ele foi realizado em 30 pacientes com enxaqueca sem queixa de vertigem e 30 controles pareados. Embora não estatisticamente significativo, ocorreu assimetria direita-esquerda superior a 25% na duração do nistagmo em ambos os grupos, maior nos pacientes, o que sugere a presença de desequilíbrio vestibular subclínico na enxaqueca.

Migraine patients consistently show abnormal vestibular bedside tests / Pacientes enxaquecosos consistentemente apresentam testes vestibulares de beira-de-leito anormais

Migraine and vertigo are common disorders, with lifetime prevalences of 16% and 7% respectively, and co-morbidity around 3.2%. Vestibular syndromes and dizziness occur more frequently in migraine patients. We investigated bedside clinical signs indicative of vestibular dysfunction in migraineurs. Objective To test the hypothesis that vestibulo-ocular reflex, vestibulo-spinal reflex and fall risk (FR) responses as measured by 14 bedside tests are abnormal in migraineurs without vertigo, as compared with controls. Method Cross-sectional study including sixty individuals – thirty migraineurs, 25 women, 19-60 y-o; and 30 gender/age healthy paired controls. Results Migraineurs showed a tendency to perform worse in almost all tests, albeit only the Romberg tandem test was statistically different from controls. A combination of four abnormal tests better discriminated the two groups (93.3% specificity). Conclusion Migraine patients consistently showed abnormal vestibular bedside tests when compared with controls.

Enxaqueca e vertigem são desordens comuns, com prevalência de 16% e 7% respectivamente, e comorbidade em torno de 3,2%. Síndromes vestibulares e tonturas ocorrem mais frequentemente em enxaquecosos. Pesquisamos alterações vestibulares utilizando testes de beira-de-leito em enxaquecosos. Objetivo Verificar se as respostas dos reflexos vestíbulo-ocular, vestíbulo-medular e risco de quedas medidas por 14 testes de beira-de-leito são diferentes comparando-se enxaquecosos sem vertigem, e controles. Método Estudo transversal com sessenta pessoas, 30 enxaquecosos; 25 mulheres, 19-60 anos; e trinta controles saudáveis pareados por sexo e idade. Resultados Houve tendência de pior desempenho entre enxaquecosos em quase todos testes, porém apenas o teste de Romberg tandem foi estatisticamente diferente dos controles. Uma combinação de quatro testes anormais discrimina os grupos com especificidade de 93,3%. Conclusão O grupo de enxaquecosos mostrou consistentemente testes vestibulares de beira-de-leito anormais quando comparados a controles.

Horizontal canal benign paroxysmal positional vertigo: diagnosis and treatment of 37 patients.

Benign paroxysmal positional vertigo (BPPV), the most frequent cause of vertigo is associated with high morbidity in the elderly population. The most common form is linked to debris in the posterior semicircular canal. However, there has been an increasing number of reported BPPV cases involving the horizontal canals. The purpose of this article is to highlight the clinical features, diagnosis, and treatment in 37 patients with horizontal canal BPPV; twenty-six with geotropic nystagmus, and eleven with the apogeotropic form. Treatment consisted of the Gufoni manoeuver in eighteen patients (48.6%), the barbecue 360° maneuver in twelve patients (32.4%), both manoeuvers in four patients (10.8%), both manoeuvers plus head shaking in one patient (2.7%), and the Gufoni maneuver plus head shaking in two patients. Cupulolithiasis patients were asked to sleep in a forced prolonged position. We obtained a complete resolution of vertigo and nystagmus in 30 patients (81.0%) on the initial visit.

Vertigem posicional paroxística benigna (VPPB) é a causa mais frequente de vertigem e promove alta morbidade na população idosa. A forma mais comum está relacionada com otoconias no canal semicircular posterior. Entretanto, nos últimos anos identifica-se cada vez mais casos de VPPB dos canais horizontais. Os principais objetivos deste artigo são destacar as características clínicas, diagnóstico e tratamentos aplicados em 37 pacientes com VPPB do canal horizontal; vinte e seis com nistagmo geotrópico, e onze com nistagmo apogeotrópico. O tratamento consistiu na manobra de Gufoni em dezoito pacientes (48,6%) manobra do churrasco 360° em doze pacientes (32,4%) ambas as manobras em quatro pacientes (10,8%) ambas as manobras mais a manobra de sacudir a cabeça (MSC) em um paciente (2,7%), e manobra de Gufoni mais MSC em dois pacientes (2,7%). Pacientes com cupulolitíase dormiram uma noite na posição forçada prolongada. Em 30 pacientes (81,0%) o sucesso terapêutico ocorreu na primeira consulta.

O "toque final" no sinal de Romberg / The final touch in Romberg signal

O sinal de Romberg foi o primeiro sinal importante descrito na neurologia. Demorou 37 anos para ficar pronto e foi William Gowers quem deu o "toque final" na maneira de pesquisá-lo. Esta Nota conta um pouco dessa história.

The Romberg sign was the first major sign described in Neurology. It took 37 years to get ready, and it was William Gowers who gave the "finishing touch" on the way to research it. This notice tells some of that story.

Paralisia facial: quantos tipos clínicos você conhece? Parte II / Facial palsy: how many clinical types do you know? Part II

Em dois manuscritos, os autores comentam aspectos clínicos de 17tipos de paralisia/paresia facial subdivididos em três grupos. Num artigo anterior (parte I), os dois primeiros grupos de paralisias faciais (periféricas e centrais) foram comentados. No presente artigo (parte II), o grupo III (outros tipos de paralisia facial) é abordado. Composto por sete fenótipos clínicos, esse grupo de prosopoplegias abrange desde a paralisia facial congênita, passando pelas paralisias faciais ramusculares e segmentares, até concluir com as paralisias faciais psicogênicas.

In two articles, the authors comment on aspects of seventeen facialparalysis/paresis types subdivided into three groups. The first article (part I) addressed the first two groups of facial paralysis (peripheral and central). At present (part II), group III (other types of facial paralysis) is approached. Composed of seven clinical phenotypes, this group ranges from congenital facial palsy, passing by branches and segmental facial paralysis, and concludes with conversive facial paralysis.

Paralisia facial: quantos tipos clínicos você conhece? Parte I / Facial falsy: how many clinical types do you know? Part I

A presente revisão aborda 17 tipos clínicos de paralisias/paresias faciais divididos em três grupos (grupo I: paralisias faciais periféricas; grupo II: paralisias faciais centrais; grupo III: outros tipos de paralisia facial). Devido à extensão do tema, ele é apresentado em duas partes. Neste primeiro artigo são comentados aspectos clínicos das paralisias faciais periféricas e centrais.

The present review discusses 17 different clinical types of facial paralysis/paresis. They were divided into three groups (group I: peripheral facial paralysis; group II: central facial paralysis; and group III: other types of facial paralysis). Because of the extension of this theme it is presented in two parts. In this first article the peripheral and central facial paralysis are addressed.

Rethinking the neurological examination I: static balance assessment / Repensando o exame neurológico I: avaliação do equilíbrio estático

The authors advocate a modernization of the neurologic exam with regard to the evaluation of static equilibrium through the application of some easily performed and interpreted bedside maneuvers like the Clinical Test of Sensory Integration and Balance - modified and the Functional Reach Test. The authors also believe that these and other assessments, such as that of the risk of falling for elderly patients, should be incorporated into the routine neurological examination.

Os autores advogam a modernização do exame neurológico no que diz respeito à pesquisa do equilíbrio estático, por meio da aplicação de algumas manobras de beira-de-leito fáceis de serem executadas e interpretadas, tais como o Teste Clínico de Integração Sensorial e Equilíbrio-modificado e o Teste do Alcance Funcional. Os autores também acreditam que estes e outros testes visando avaliação de risco de queda em pacientes idosos devem fazer parte do exame neurológico de rotina.

Rethinking the neurological examination II: dynamic balance assessment / Repensando o exame neurológico II: avaliação do equilíbrio dinâmico

The authors propose that the neurological exam needs reevaluation with respect to the dynamic balance test (walking). Validated tests such as: preferred and maximum gait speed, dynamic gait index, five-times-sit-to-stand test, timed up & go cognitive and manual, should be part of the neurological examination routine. In the neurological exam of older patients, these same bedside tests bring the plus of evaluation the risk of occasional falling.

Os autores propõem que o exame neurológico tradicional seja reavaliado no que diz respeito ao exame do equilíbrio dinâmico (marcha). Testes validados tais como: velocidade da marcha - preferencial e máxima; índice dinâmico da marcha, teste senta-levanta cinco vezes e o tempo levanta-e-anda cognitivo e manual, deveriam fazer parte do exame neurológico de rotina. Na avaliação neurológica dos pacientes idosos, esses mesmos testes à beira do leito trazem benefício adicional ao aferir o risco de queda ocasional.
