ABSTRACT
Abstract Introduction Benign Paroxysmal Positional Vertigo (BPPV) is the most common vestibular disorder, resulting from detached otoliths that migrate to one of the semicircular canals - canalolithiasis - or one of the cupulas - cupulolithiasis. The present study is related to lateral canal BPPVs, which may be either geotropic or apogeotropic. The geotropic variant of lateral semicircular canal benign paroxysmal positional vertigo (LC-BPPV) is attributed to free floating particles in the posterior arm of the lateral semicircular canal. Objectives To verify the possibility of employing the Zuma repositioning maneuver, with a brief modification, as an alternative treatment for geotropic LC-BPPV. Methods Seven patients with geotropic LC-BPPV were enrolled and treated with the Zuma modified maneuver. Patients were reevaluated 1 hour after a single maneuver, to confirm the resolution of vertigo and positional nystagmus. Results All seven patients achieved immediate resolution of vertigo and positional nystagmus as measured 1 hour after the application of the maneuver. Conclusion The Zuma modified maneuver was effective for geotropic LC-BPPV after a single application. The use of the Zuma maneuver for both apogeotropic and geotropic LC-BPPV may simplify the treatment of these patients.
ABSTRACT
Os acidentes com animais peçonhentos compõem um amplo grupo de afecções atendidas nas unidades de emergência. Apresentamos neste trabalho as medidas iniciais de diagnóstico e tratamento dos agentes mais comuns no Rio Grande do Sul: ofídios (Bothrops), aranhas (Loxosceles) e lagartas (Lonomia).
Accidents with poisonous animals make up a large group of conditions met in the emergency room. We present in this work the initial steps of diagnosis and treatment of the most common agents in Rio Grande do Sul: snakes (Bothrops), spiders (Loxosceles) and caterpillars (Lonomia).

A síndrome do olho seco é uma doença crônica, caracterizada pela diminuição da produção da lágrima ou deficiência em alguns de seus componentes que resulta em desconforto ocular e instabilidade lacrimal, podendo acarretar um significativo impacto na acuidade visual e qualidade de vida. O objetivo principal deste artigo é revisar o diagnóstico e manejo dessa síndrome.
Dry eye syndrome is a chronic disease characterized by decreased tear production or disability in any of its components that results in ocular discomfort and tear instability, which may cause a significant impact on visual acuity and quality of life. The main purpose of this article is to review the diagnosis and management of this syndrome.
