Rio de Janeiro, RJ, Brasil.Embora as infecções virais sistêmicas sejam muito comuns, as infecções virais sintomáticas do parênquima cerebral são raras, mas potencialmente graves. Estima-se que a encefalite viral ocorra em 1,4 casos por 100.000 habitantes anualmente. A localização geográfica é um fator determinante a ser levado em consideração frente aos patógenos transmitidos por vetores. O diagnóstico clínico das encefalites virais pode ser um desafio para o clínico, visto que quase 70% dos casos de encefalite viral ficam sem a identificação do agente viral. Nesta revisão, as encefalites virais mais comuns serão discutidas, com interesse especial sobre os aspectos da ecologia, do diagnóstico e do seu manejo clínico.While systemic viral infections are exceptionally common, symptomatic viral infections of the brain parenchyma itself are very rare, but a serious neurologic condition. It is estimated that viral encephalitis occurs at a rate of 1.4 cases per 100.000 inhabitants. Geography is a major determinant of encephalitis caused by vector-borne pathogens. A diagnosis of viral encephalitis could be a challenge to the clinician, since almost 70% of viral encephalitis cases are left without an etiologic agent identified. In this review, the most common viral encephalitis will be discussed, with focus on ecology, diagnosis, and clinical management

Niterói RJ, Brazil.A injeção de polimetilmetacrilato (PMMA) é prática difundida na medicina estética como medida rejuvenecedora. No entanto, a injeção facial do PMMA carreia sérios riscos, especialmente se realizada na região glabelar. Descrevemos o caso de uma mulher que imediatamente após injeção glabelar de PMMA apresentou amaurose e oftalmoplegia total, revendo ainda a literatura pertinente.Microspheres of polymethyl-methacrylate (PMMA) are exciting new soft-tissue fillers that are becoming increasing popular for facial rejuvenation. Some reports of side effects of this procedure are basically in respect to dermal reaction, with late-onset granulomatous lesion with giant cells and vacuoles. We report blindness and total ophthalmoplegia after PMMA injection into glabellar area in a healthy woman and review the literature

    HIV-associated neurocognitive disorders (HAND) remain prevalent in highly active antiretroviral therapy (HAART) era. Tests to detect HAND are needed for early diagnosis and treatment. Validity of International HIV Dementia Scale (IHDS) has been determined in different countries. The aims of this study were validate IHDS in a Brazilian cohort of HIV-patients and verify if IHDS can be reliably administered by a non-clinician health professional. One hundred and eighty-seven (187) patients were submitted to a full neuropsychological assessment. IHDS was administered twice to each patient (by a non-clinician and by a neurologist). HAND was diagnosed in 98 individuals (68 on HAART). IHDS had sensitivity of 55% and specificity of 80%. IHDS had fair agreement with neuropsychological tests (k 0.355) and moderate-to-strong agreement between different evaluators (interclass correlation coefficient (ICC) 0.684). HAND is prevalent nowadays. IHDS is quick and easy to administer, but has marginal sensitivity for the detection of HIV cognitive impairment other than dementia

    We are grateful to Professor William W. Hall, MD, PhD (CRID, University College Dublin, Ireland) for his useful suggestions. We thank Dr. Lara Brandão, MD (Clinica Radiologica Felipe Mattoso, Rio de Janeiro, Brazil), for the MRI report of the microcephaly case.Submitted by Éder Freyre ([email protected]) on 2016-08-03T12:37:54Z No. of bitstreams: 1 INI - Zika virus-associated neurological disorders - a review.pdf: 318310 bytes, checksum: 798e79026fb1f1d9e32c3811e1ec5063 (MD5)Approved for entry into archive by Éder Freyre ([email protected]) on 2016-08-03T13:08:57Z (GMT) No. of bitstreams: 1 INI - Zika virus-associated neurological disorders - a review.pdf: 318310 bytes, checksum: 798e79026fb1f1d9e32c3811e1ec5063 (MD5)Made available in DSpace on 2016-08-03T13:08:57Z (GMT).

Rio de Janeiro, RJ, Brasil.Zika virus, an arbovirus transmitted by mosquitoes of the Aedes species, is now rapidly disseminating throughout the Americas and the ongoing Brazilian outbreak is the largest Zika virus epidemic so far described. In addition to being associated with a non-specific acute febrile illness, a number of neurological manifestations, mainly microcephaly and Guillain-Barré syndrome, have been associated with infection. These with other rarer neurological conditions suggest that Zika virus, similar to other flaviviruses, is neuropathogenic. The surge of Zika virus-related microcephaly cases in Brazil has received much attention and the role of the virus in this and in other neurological manifestations is growing. Zika virus has been shown to be transmitted perinatally and the virus can be detected in amniotic fluid, placenta and foetus brain tissue. A significant increase in Guillain-Barré syndrome incidence has also been reported during this, as well as in previous outbreaks. More recently, meningoencephalitis and myelitis have also been reported following Zika virus infection. In summary, while preliminary studies have suggested a clear relationship between Zika virus infection and certain neurological conditions, only longitudinal studies in this epidemic, as well as experimental studies either in animal models or in vitro, will help to better understand the role of the virus and the pathogenesis of these disorders

Rio de Janeiro RJ, Brasil.As epidemias provocadas pelo vírus Chikungunya (CHIK) e Zika vírus (ZIKV) têm sido consideradas as ocorrências epidemiológicas mais importantes da América. O quadro clínico da infecção por CHIK caracteriza-se por febre alta, exantema, mialgia, cefaléia e artralgia. Além do quadro clínico típico, manifestações atípicas como complicações neurológicas foram relatadas: meningo-encefalite, mielorradiculopatia, mielorradiculite, mielite, mieloneuropatia, síndrome de Guillain-Barre (GBS), entre outras. O diagnóstico é baseado em critérios clínicos, epidemiológicos e laboratoriais. Em relação aos sinais e sintomas da infecção pelo ZIKV, erupção cutânea (principalmente maculopapular), febre, artralgia, mialgia, cefaléia e conjuntivite são os mais comuns. Algumas epidemias que ocorreram recentemente na Polinésia Francesa e Brasil relataram condições mais severas, com envolvimento do sistema nervoso (GBS, mielite transversa, microcefalia e meningite). O tratamento para ZIKV e CHIK é sintomático, e o manejo das complicações neurológicas dependerá do tipo da afecção. Imunoglobulina venosa, plasmaférese, e pulsoterapia com corticosteróides são opções.The epidemics of Chikungunya virus (CHIKV) and Zika virus (ZIKV) infections have been considered the most important epidemiological occurrences in the Americas. The clinical picture of CHIKV infection is characterized by high fever, exanthema, myalgia, headaches, and arthralgia. Besides the typical clinical picture of CHIKV, atypical manifestations of neurological complications have been reported: meningo-encephalitis, meningoencephalo-myeloradiculitis, myeloradiculitis, myelitis, myeloneuropathy, Guillain-Barré syndrome and others. The diagnosis is based on clinical, epidemiological, and laboratory criteria. The most common symptoms of ZIKV infection are skin rash (mostly maculopapular), fever, arthralgia, myalgia, headache, and conjunctivitis. Some epidemics that have recently occurred in French Polynesia and Brazil, reported the most severe conditions, with involvement of the nervous system (Guillain-Barré syndrome, transverse myelitis, microcephaly and meningitis). The treatment for ZIKV and CHIKV infections are symptomatic and the management for neurological complications depends on the type of affliction. Intravenous immunoglobulin, plasmapheresis, and corticosteroid pulse therapy are options
