Menopausa: principais sinais e sintomas à avaliação vestibular computadorizada

Objetivo: Identificar os principais sintomas e sinais ao exame vestibular computadorizado em pacientes na menopausa. Método: Foram examinadas 24 pacientes com idades entre 46 a 66 anos. Analisaram-se os dados relativos à sintomatologia e achados ao exame vestibular computadorizado com vectonistagmografia realizado no ambulatório de otoneurologia da Irmandade Santa Casa de Misericórdia de São Paulo, em 2004 e 2005. Resultados: Entre as pacientes, 54,1 por cento faziam reposição hormonal. Em relação aos sintomas relatados, observamos cefaléia (58,4 por cento), hipersensibilidade a sons intensos (58,4 por cento), tontura (54,2 por cento), zumbido (50 por cento), hipoacusia (50 por cento), ansiedade (50 por cento), distúrbio neurovegetativo (41,7 por cento), vertigem (37,5 por cento) e depressão (37,5 por cento). Ao exame vestibular encontramos alterações do nistagmo de posicionamento (12,5 por cento), e prova calórica (54,2 por cento). Na conclusão do exame tivemos prevalência de síndrome vestibular periférica irritativa (54,2 por cento). Conclusão: Por meio dos resultados desta pesquisa concluiu-se que pacientes no período da menopausa apresentam elevada prevalência de sintoma otoneurológicos e alterações à vectonistagmografia computadorizada, com predomínio de síndrome vestibular periférica do tipo irritativo

Basilar artery occlusive disease in stroke survivors in a multiethnic population

Objectives: To describe clinical, radiological findings, and outcome in a multiethnic population of stroke survivors with basilar artery occlusive disease (BAOC). Methods: Forty patients with infarcts in the basilar artery (BA) territory, alive 30 days after the ictus, participated in the study. BA stenosis (>50%) or occlusion was shown by magnetic resonance or digital subtraction angiography in all patients. Demographical, clinical and radiological characteristics were described. Modified Rankin Scale (MRS) scores at 30 days and 6 months after the ischemic event were evaluated. Association between demographical, clinical, radiological features and outcome were analyzed with Chi-square and Fisher`s exact tests. MRS scores at 30 days and 6 months were compared with the Wilcoxon test. Results: Sixty percent of the patients were men, and 33% were Afro-Brazilian. Mean age was 55.8 +/- 12.9 years. Most (90%) had multiple vascular risk factors. Stroke was preceded by TIA in 48% of the patients, and 80% had a history of arterial hypertension. The most common neurological symptom was vertigo/dizziness (60%) and the sign, hemiparesis (60%). Most of the infarcts were located in the pons (85%) and the BA middle third was the most frequently affected segment (33%). BA occlusion occurred in 58% of the patients. More severe vascular occlusive lesions were present in Whites (p = 0.002) and in patients with involvement of the middle third of the BA (p = 0.021). Large-artery atherosclerosis was the most common stroke etiology (88%) and was more frequent in older patients (p < 0.001). Most patients were treated with anticoagulation. MRS scores improved significantly at 6 months (p < 0.001): at this time, 78% of the patients had MRS scores between 0 and 2. Conclusions: We observed different results compared with other series: greater proportion of Afro-descendents, higher frequency of atherosclerosis and BA occlusion. Rates of preceding TIAs and good outcome at 6 months were similar to previously published data. These results represent a step forward towards understanding BAOC in a multiethnic context.

Quality of life in elderly with dizziness

Dizziness is frequent in elderly people. Aims: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age. Material and Method: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI). The factor analysis (FA), the Mann Whitney and Kruskal Wallis tests, and the Spearman correlation were applied to study the results. Results: The most compromised domains were the DHI physical domain and the Whoqol-bref physical and environment domains. FA resulted in 3 factors in the DHI and 5 factors in the Whoqol-bref. There was a moderate correlation (-0.596) in the total scores of both instruments. Males had a better QoL in the ""environment perception and introspectivity"" and ""health perception"" factors of the Whoqol-bref test. Females had a better QoL in the ""functionality perception"" factor of the Whoqol-bref test. There were no significant age differences. Conclusions: Elderly patients with dizziness have a worse QoL. Elderly females with dizziness have worse QoL scores in ""environment perception and introspectivity"" and ""health perception"" and better QoL in the ""functionality perception"" factor compared to elderly males.

Conduct after Epley`s maneuver in elderly with posterior canal BPPV in the posterior canal

Benign Paroxysmal Positional Vertigo is the most common peripheral vestibular disorder, especially in the elderly and presents as the predominant etiology in this population of the degeneration of the utricular macula. Aim: To compare the effectiveness of the approaches after Epley maneuver. Study Design: longitudinal cohort. Materials and Methods: The study included 53 volunteers with Benign Paroxysmal Positional Vertigo of the posterior semicircular canal, divided into Group 1, who underwent Epley maneuver associated with the use of neck collar and post-maneuver instructions, Group 2 underwent the Epley maneuver without the use cervical collar and/or post-maneuver restrictions, and Group 3 underwent the Epley maneuver associated with the use of a mini vibrator, without the use of neck collar and/or post-maneuver restrictions. Results: In the three groups, the number of Epley maneuvers ranged from one to three. We employed the Brazilian Dizziness Handicap Inventory - pre- and post-treatment and observed a statistically significant difference on most scores pre- and post-treatment for both groups. Conclusion: Regardless of the post Epley maneuver treatment selected for the treatment of Benign Paroxysmal Positional Vertigo, it was effective when comparing the Brazilian Dizziness Handicap Inventory pre- and post-treatment.
