Independência funcional, aspectos clínicos e fatores sociodemográficos em pacientes na fase aguda do Acidente Vascular Cerebral: uma análise de associação / Functional independence, clinical aspects, and sociodemographic factors in patients in the acute phase of stroke: an association analysis

RESUMO Objetivo Analisar a associação da independência funcional com aspectos clínicos de comprometimento neurológico, a localização e extensão do dano neuronal e os fatores sociodemográficos em pacientes na fase aguda do AVC. Método Estudo analítico de recorte transversal, realizado com 90 pacientes adultos e idosos acometidos por AVC isquêmico, que tiveram admissão no ambiente hospitalar nas primeiras 24 horas após o evento vascular. A coleta dos dados referentes aos aspectos clínicos e fatores sociodemográficos foi realizada pelo prontuário eletrônico e/ou entrevista para descrever o perfil dos pacientes, Oxfordshire Community Stroke Project, Alberta Stroke Programme Early CT Score, National Institute of Health Stroke Scale e a Medida de Independência Funcional. Resultados O comprometimento neurológico, de acordo com a National Institute of Health Stroke Scale, foi associado à funcionalidade nas primeiras 24 horas após o AVC. Além disso, a presença de hipertensão arterial, idade, trabalho inativo, tabagismo e extensão do dano neuronal estiveram associados à dependência funcional, mas não permaneceram no modelo final deste estudo. Conclusão A dependência funcional está associada à hipertensão arterial, idade, trabalho inativo, tabagismo, extensão do dano neuronal e grau de comprometimento neurológico nas primeiras 24 horas após o evento vascular. Além disso, um nível mais elevado de comprometimento neurológico foi independentemente associado a níveis aumentados de dependência funcional.

ABSTRACT Purpose To analyze the association of functional independence with clinical aspects of neurological impairment, the location and extent of neuronal damage and sociodemographic factors in patients in the acute phase of stroke. Methods Analytical cross-sectional study in 90 adult and older patients affected by ischemic stroke, admitted to the hospital within 24 hours of the vascular event. Sociodemographic factors and clinical aspects data were collected from electronic medical records and/or interviews in order to depict the patients'profile, Oxfordshire Community Stroke Project, Alberta Stroke Programme Early CT Score, National Institute of Health Stroke Scale, and Functional Independence Measure. Results Neurological impairment, according to the National Institute of Health Stroke Scale, was associated with functioning in the first 24 hours after the stroke. Furthermore, the presence of arterial hypertension, age, inactive work, smoking and extent of neuronal damage were associated with functional dependence, but did not remain in the final model of this study. Conclusion Functional dependence is associated with arterial hypertension, age, inactive work, smoking, extent of neuronal damage, and degree of neurological impairment in the first 24 hours after the vascular event. Furthermore, a higher level of neurological impairment was independently associated with increased levels of functional dependence.

Quality of life predictors for people living with HIV/AIDS in an impoverished region of Brazil

Abstract INTRODUCTION: Quality of life (QoL) is important for people living with HIV/AIDS, particularly as the disease progresses. This study evaluated the QoL of people living with HIV/AIDS (PLWHA), as well as its predictors, in one of the most impoverished regions of Brazil. METHODS: This cross-sectional study was conducted with patients older than 18 years with HIV/AIDS from two specialized HIV/AIDS care centers in the city of Montes Claros between 2013 and 2014. Sample size was calculated considering the estimates of mean scores for various dimensions of the European Portuguese version of the World Health's Organization Quality of Life Instrument in HIV Infection (WHOQOL-HIV Bref). The following parameters were adopted: CI of 95%, estimated mean scores for QoL equal to 15, estimated variance for QoL scores equal to 16, and 5% relative margin of error. An increase of 20% was established to compensate for possible non-responses or losses, and correcting any design effect, adopting a deff equal to 2.0. Calculations revealed the need to interview at least 221 patients. Therefore, 226 patients living with HIV/AIDS were randomly selected. RESULTS: A total of 226 patients with mean age 43.7 years were evaluated: 51.8% men, 51.8% unemployed, 51.8% with low schooling level, 89.8% used antiretrovirals, and 43.3% experienced depression. Despite this, data indicated that 65% self-assessed their QoL as good and very good. Low QoL was associated with sociodemographic variables and some clinical variables. CONCLUSIONS: Depression was the main predictor of low QoL in all domains evaluated.

Epidemiologia do traumatismo cranioencefálico no Brasil / Epidemiology of traumatic brain injury in Brazil

Introdução: O traumatismo cranioencefálico (TCE) é considerado a maior causa de morte e incapacidade em todo mundo, principalmente entre adultos jovens. No Brasil, estima-se que mais de um milhão de pessoas vivam com sequelas neurológicas decorrentes do TCE. Apesar da sua alta prevalência e taxas de incidência em constante elevação, estudos epidemiológicos permanecem escassos. Objetivo: Discutir as evidências disponíveis em relação ao perfil epidemiológico da população brasileira acometida por TCE. Métodos: Realizou- se uma revisão de literatura nas bases de dados SciELO, LILACS e PubMed. Os termos utilizados na busca foram traumatismo cranioencefálico, e/ou epidemiologia, e/ou Brasil. Para a busca no PubMed foram utilizados os termos em inglês traumatic brain injury, e/ou epidemiology, e/ou Brazil. Foram incluídos artigos originais, descritivos e de revisão que não restringiram a causa, a gravidade do TCE e a faixa etária estudada. Resultados: Foram encontrados oito estudos de 1993 a 2015, todos retrospectivos, sendo cinco deles realizados em hospitais de emergência e três baseados em bancos de dados. Indivíduos com menos de 40 anos, do sexo masculino foram os mais acometidos e as causas principais foram quedas e os acidentes de trânsito, destacando-se os motociclísticos. Conclusão: Estudos epidemiológicos robustos sobre o TCE no Brasil ainda são escassos. Todos os estudos foram retrospectivos e apenas dois apresentaram dados nacionais. Nesse contexto, estudos epidemiológicos de caráter prospectivo que investiguem de forma sistemática os fatores associados ao TCE, são urgentemente recomendados. (AU)

Introduction: Traumatic brain injury (TBI) is the leading cause of death and disability worldwide, especially among young adults. In Brazil, it is estimated that more than one million people live with disabilities due to TBI. Despite the high incidence of TBI and related socioeconomic burden, epidemiological studies are scarce. Objective: To discuss the available evidence regarding the epidemiological profile of Brazilian people victims of TBI. Methods: A literature review was conducted on the SciELO, LILACS and PubMed databases. The terms used were traumatic brain injury and/or epidemiology, and/or Brazil. Original, descriptive and review studies that investigated only one specific cause of TBI, only one level of severity or a specific age group were not included in the current review. Results: Eight retrospective articles published between 1993 and 2015 were included. Five studies were conducted in emergency hospitals and three studies were based on databases records. Men under 40 years old were the most affected group, and the main causes of TBI were falls and traffic accidents, especially involving motorcycle. Conclusion: Sound epidemiological studies on TBI are still rare. All studies included were retrospective and only two reported national data. In this scenario, prospective epidemiological studies that systematically investigate the profile of TBI victims in Brazil are urgently necessary. (AU)

Amnésia global transitória: epidemiologia, fisiopatologia, clínica e terapêutica / Global transient amnesia: epidemiology, pathophysiology, clinical features and therapeutics

A amnésia global transitória (AGT) é um quadro súbito de amnésia global, não acompanhada de outros déficits neurológicos, com duração de duas a 24 horas e cuja recuperação se dá espontaneamente. A incidência na população geral está estimada em 5-10 casos/100.000 pessoas/ano. Diferentes mecanismos fisiopatológicos, como fatores vasculares ou epiléticos, têm sido propostos para explicar a AGT, sendo consensual que haja acometimento transitório de regiões do hipocampo e do giro para-hipocampal. Além da amnésia anterógrada acompanhada por amnésia retrógrada, o paciente apresenta desorientação (tempo/espaço), estando preservadas outras habilidades cognitivas, como memória semântica e capacidades visuo-construtivas. Esses déficits tendem a remitir após 24h, sendo o prognóstico favorável na maioria dos casos. O diagnóstico diferencial de AGT é amplo e diversas condições clínicas, como eventos cérebro-vasculares, epilepsias, infecções e intoxicações podem mimetizá-lo, de modo que uma investigação clínica cuidadosa é imperativa. As recorrências não são frequentes nos quadros típicos. A AGT não requer tratamento específico, mas devem ser tratados fatores de risco cardiovascular eventualmente identificados durante a propedêutica de AGT. O clínico deve esclarecer o paciente a respeito do caráter benigno da AGT. Estudos com seguimento longitudinal dos pacientes são necessários para maior compreensão dos mecanismos fisiopatológicos da AGT e para melhor compreensão clínica e neuro- biológica dos déficits cognitivos apresentados por esses pacientes.

Global transient amnesia (GTA) is a clinical syndrome characterized by the sudden onset of anterograde and retrograde amnesia, without permanent neurological deficits, and which presents complete remission spontaneously within 2 to 24 hours. The incidence of GTA in the general population ranges from 5 to 10 cases per 100.000 individuals/ year. Different pathophysiological mechanisms have been proposed for GTA, such as vascular or epileptic factors, and it is consensual that there is transitory involvement of hippocampal and parahippocampal gyri in this condition. In addition to anterograde and retrograde amnesia, GTA patients typically present time-space disorientation, with the preservation of other cognitive abilities, such as semantic memory and visuoconstructive capacities. The differential diagnosis includes stroke, epilepsy, infections and intoxication, and a careful clinical investigation is essential to establish the GTA diagnosis. Recurrence is uncommon in typical cases and, in general, no specific treatment is required. However, clinical investigation of GTA may eventually disclose cardiovascular risk factors; these factors should be treated when identified. GTA is considered a benign condition, with good clinical and cognitive prognostics in most of the cases. More studies are needed to advance the current knowledge on the pathophysiology and on the neural basis of the transitory cognitive impairment observed in GTA.

Determinants of quality of life in Brazilian patients with myasthenia gravis

OBJECTIVES: The aims of the current study were 1) to evaluate the reliability and validity of the Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale and 2) to investigate the quality of life of Brazilian patients with myasthenia gravis and its determinants. METHODS: This cross-sectional study included 69 patients with myasthenia gravis who underwent neurological evaluation and completed questionnaires regarding quality of life (the 36-item Short Form of the Medical Outcomes Study and the 15-item Myasthenia Gravis Quality of Life Scale), anxiety and depressive symptoms. RESULTS: The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale showed high internal consistency and good concurrent validity with the 36-item Short Form of the Medical Outcomes Study and its subscales. Determinants of quality of life in Brazilian patients with myasthenia gravis included the current status of myasthenia gravis as assessed by the Myasthenia Gravis Composite, the current prednisone dose and the levels of anxiety and depression. CONCLUSION: The Brazilian version of the 15-item Myasthenia Gravis Quality of Life Scale is a valid instrument. Symptom severity, prednisone dosage and anxiety and depression levels impact the quality of life of patients with myasthenia gravis.

Frequência e fatores associado à disfagia após acidente vascular cerebral / Frequency and factors associated with dysphagia in stroke

RESUMO Objetivo: Verificar a frequência de disfagia em pacientes acometidos por acidente vascular cerebral (AVC) e investigar possíveis fatores sociodemográficos e clínicos associados. Método: Trata-se de estudo descritivo do tipo transversal em que foram avaliados 100 pacientes admitidos com o diagnóstico de AVC no Hospital Público Regional de Minas Gerais. Dados sociodemográficos e clínicos foram obtidos, e os pacientes, submetidos à avaliação clínica da deglutição por meio da escala Gugging Swallowing Screen (GUSS). Resultados: A frequência da disfagia foi de 50%, sendo que a maioria dos pacientes apresentou alteração grave da deglutição. Apenas história pregressa de AVC mostrou associação com disfagia (p=0,02). Outras variáveis sociodemográficas e clínicas não se associaram com disfagia, indicando que a localização e a fisiopatologia do AVC não influenciaram sua ocorrência e gravidade. Conclusão: A frequência de disfagia após o AVC é elevada, sendo o histórico de AVC importante fator de risco.

ABSTRACT Purpose: To investigate the frequency of dysphagia in acute stroke and the possible associated clinical and sociodemographic features. Method: A cross-sectional study was performed including 100 stroke patients who were admitted to the Minas Gerais Regional Public Hospital. Sociodemographic and clinical data were collected, and the patients underwent clinical evaluation through the Gugging Swallowing Screen (GUSS). Results: The frequency of dysphagia was 50%, and most patients had severe swallowing disorders. Only a previous history of stroke was associated with dysphagia (p=0.02). Other sociodemographic and clinical variables were not associated with dysphagia, suggesting that the location and the pathophysiology of stroke did not influence its occurrence and severity. Conclusion: The frequency of dysphagia after stroke is high, being a previous stroke an important risk factor for subsequent stroke.

Sexual dysfunction and dissatisfaction in chronic hepatitis C patients

Introduction The prevalence of sexual dysfunction (SD) and dissatisfaction with sexual life (DSL) in patients with chronic hepatitis C virus infection (CHC) was jointly investigated via a thorough psychopathological analysis, which included dimensions such as fatigue, impulsiveness, psychiatric comorbidity, health-related quality of life (HRQL) and sociodemographic and clinical characteristics. Methods Male and female CHC patients from an outpatient referral center were assessed using the Brief Fatigue Inventory, the Barrat Impulsiveness Scale, the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale, the Hamilton Anxiety Scale (HAM-A), and the World Health Organization Quality of Life Scale-Brief Version (WHOQOL-BREF). Structured psychiatric interviews were performed according to the Mini-International Neuropsychiatric Interview. SD was assessed based on specific items in the BDI (item 21) and the HAM-A (item 12). DSL was assessed based on a specific question in the WHOQOL-BREF (item 21). Multivariate analysis was performed according to an ordinal linear regression model in which SD and DSL were considered as outcome variables. Results SD was reported by 60 (57.1%) of the patients according to the results of the BDI and by 54 (51.4%) of the patients according to the results of the HAM-A. SD was associated with older age, female gender, viral genotype 2 or 3, interferon-α use, impulsiveness, depressive symptoms, antidepressant and benzodiazepine use, and lower HRQL. DSL was reported by 34 (32.4%) of the patients and was associated with depressive symptoms, anxiety symptoms, antidepressant use, and lower HRQL. Conclusions The prevalence of SD and DSL in CHC patients was high and was associated with factors, such as depressive symptoms and antidepressant use. Screening and managing these conditions represent significant steps toward improving medical assistance and the HRQL of CHC patients. .

Alterações cognitivas na doença renal crônica: uma atualização / Cognitive alterations in chronic kidney disease: an update

Prejuízos das funções cognitivas ocorrem com frequência na doença renal crônica (DRC). As condições mais associadas a esses prejuízos são depressão, delirium, comprometimento cognitivo leve e demência. Os mecanismos envolvidos ainda não estão estabelecidos, mas alguns fatores, como dano neuronal induzido pelas toxinas urêmicas, lesões cerebrovasculares isquêmicas, estresse oxidativo, inflamação crônica, anemia, hiper-homocisteinemia e disfunção endotelial, podem ser importantes. O desempenho neuropsicológico tende a melhorar com o início da diálise, apesar de algumas disfunções cognitivas permanecerem alteradas mesmo após a instituição do tratamento, principalmente nos domínios de atenção, flexibilidade cognitiva, memória e aprendizagem. O transplante renal pode melhorar e, inclusive, reverter alguns déficits cognitivos, apesar de prejuízos na memória verbal e nas funções executivas poderem permanecer. O diagnóstico do declínio cognitivo nos pacientes renais crônicos pode ter impacto no manejo e no prognóstico. Este artigo apresenta uma atualização sobre declínio das funções cognitivas nos pacientes com DRC.

Impairment of cognitive functions occurs frequently in chronic kidney disease (CKD). The conditions most associated with this decline are depression, delirium, mild cognitive impairment and dementia. The mechanisms involved have not been established yet, but some factors, as neuronal damage by uremic toxins, cerebrovascular ischemic lesions, oxidative stress, chronic inflammation, anemia, hyperhomocysteinemia, the endothelial dysfunction may play a critical role. The neuropsychological performance improves with the initiation of dialysis, although some cognitive dysfunctions remain even after treatment, especially in the areas of attention, cognitive flexibility, memory and learning. Kidney transplantation may improve and even reverse some cognitive deficits detected in the dialysis period, despite some compromise in verbal memory and executive functions remain after transplantation. The diagnosis of cognitive decline in patients with CKD may have an important impact on the management and prognosis. This paper presents an update on the decline of cognitive function in patients with CKD.

Temporo-mandibular disorders are an important comorbidity of migraine and may be clinically difficult to distinguish them from tension-type headache / Desordens temporomandibulares sao comorbidade importante da migranea e podem ser clinicamente dificeis de distinguir da cefaleia tipo tensional

Clinical differentiation between the primary headaches and temporomandibular disorders (TMD) can be challenging. Objectives : To investigate the relationship between TMD and primary headaches by conducting face to face assessments in patients from an orofacial pain clinic and a headache tertiary center. Method : Sample consists of 289 individuals consecutively identified at a headache center and 78 individuals seen in an orofacial pain clinic because of symptoms suggestive of TMD. Results : Migraine was diagnosed in 79.8% of headache sufferers, in headache tertiary center, and 25.6% of those in orofacial pain clinic (p<0.001). Tension-type headache was present in 20.4% and 46.1%, while the TMD painful occurred in 48.1% and 70.5% respectively (p<0.001). Conclusion : TMD is an important comorbidity of migraine and difficult to distinguish clinically from tension-type headache, and this headache was more frequent in the dental center than at the medical center. .

Método : A amostra consistiu de 289 indivíduos avaliados consecutivamente em um centro terciário de cefaleia e 78 indivíduos de uma clínica orofacial. Resultados : A migrânea foi diagnosticada em 79,8% dos pacientes do centro de cefaleia e 25,6% dos pacientes do centro de dor orofacial. A cefaleia do tipo tensional esteve presente em 20,4% e 46,1%, enquanto as DTM dolorosas ocorreram em 48,1% e 70,5% respectivamente (p<0,001). Conclusão : DTM é uma comorbidade importante da migrânea e difícil de distinguir clinicamente da cefaleia do tipo tensional, tanto que esta cefaleia foi mais frequente no centro odontológico do que no centro médico. .

Health related quality of life among patients with chronic hepatitis C: a cross-sectional study of sociodemographic, psychopathological and psychiatric determinants

INTRODUCTION: Chronic hepatitis C virus infection patients have higher rates of psychiatric disorders than the general population. Chronic hepatitis C virus infection is known to be associated with impaired health related quality of life. To our knowledge, there is no previous research of health related quality of life in chronic hepatitis C patients that combined structured psychiatric interview and careful psychopathological evaluation, including depression, anxiety and fatigue instruments. The aim of this study was to evaluate health related quality of life of chronic hepatitis C patients and to investigate the association with sociodemographic, psychopathological and psychiatric factors. MATERIALS AND METHODS: Eighty-one individuals with chronic hepatitis C virus infection receiving care at a Brazilian public university-based outpatient service for infectious diseases were enrolled in the study. The World Health Organization Quality of Life Scale Brief Version was used to assess health related quality of life. Standard psychiatric interview (Mini International Neuropsychiatric Interview-Plus) was conducted to establish Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I psychiatric diagnosis. Further instruments completed psychopathological investigation: Beck Depression Inventory, Hospital Anxiety and Depression Scale, Brief Fatigue Inventory, Hamilton Depression Scale and Hamilton Anxiety Scale. Pearson Chi-Square and Kruskal-Wallis were performed for categorical and continuous univariate analysis, respectively. Correlation between psychopathological and health related quality of life scores was performed according to Spearman's correlation. Multivariate analysis was performed according to stepwise forward ordinal logistic regression. The significance threshold was fixed at α = 0.05. RESULTS: Depressive disorders were associated with worse scores in overall health related quality of life and in all domains. Fatigue was associated with lower scores in physical and psychological domains, and married status with higher scores in psychological health related quality of life. We found strong correlation among scores of depression, fatigue and health related quality of life. CONCLUSION: Depression and fatigue must be properly investigated and managed in HCV patients in order to improve HRQL. WHOQOL-BREF proved to be a useful instrument to assess HRQL in HCV patients.

Paracoccidioidomycosis case series with and without central nervous system involvement / Série de casos de paracoccidioidomicose com e sem envolvimento do sistema nervoso central

INTRODUCTION: Paracoccidioidomycosis (PCM) is the most important systemic mycosis in South America. Central nervous system involvement is potentially fatal and can occur in 12.5% of cases. This paper aims to contribute to the literature describing eight cases of neuroparacoccidioidomycosis (NPMC) and compare their characteristics with patients without neurological involvement, to identify unique characteristics of NPCM. METHODS: A cohort of 213 PCM cases was evaluated at the Infectious Diseases Clinic of the University Hospital, Federal University of Minas Gerais, Brazil, from October 1976 to August 2008. Epidemiological, clinical, laboratory, therapeutic and follow-up data were registered. RESULTS: Eight patients presented NPCM. The observed NPCM prevalence was 3.8%. One patient presented the subacute form of PCM and the other seven presented the chronic form of the disease. The parenchymatous form of NPCM occurred in all patients. 60% of the patients who proceeded from the north/ northeast region of Minas Gerais State developed NPCM. The neurological involvement of a mother and her son was observed. NPCM patients exhibited demographical and clinical profiles similar to what is described in the literature. When NPCM cases were compared to PCM patients, there were differences in relation to origin and positive PCM family history. CONCLUSIONS: The results corroborate the clinical view that the neurological findings are extremely important in the evaluation of PCM patients. Despite the limitations of this study, the differences in relation to patient's origins and family history point to the need of further studies to determine the susceptibility factors involved in the neurological compromise.

INTRODUÇÃO: A paracoccidioidomicose (PCM) é a micose profunda mais importante na América do Sul. O comprometimento do sistema nervoso central é grave e pode ocorrer em 12,5% dos casos. Este trabalho tem como objetivo descrever oito casos de neuroparacoccidioidomicose (NPMC) e comparar suas características com pacientes sem envolvimento neurológico, a fim de identificar aspectos singulares da NPCM. MÉTODOS: Uma coorte de 213 casos de PCM foi avaliada na Clínica de Doenças Infecciosas do Hospital das Clínicas da Universidade Federal de Minas Gerais, de outubro de 1976 a agosto de 2008. Dados epidemiológicos, clínicos, laboratoriais, terapêuticos e de seguimento foram registrados. RESULTADOS: Oito pacientes apresentaram NPCM. A prevalência de NPCM observada foi de 3,8%. Um paciente apresentou a forma subaguda da PCM e sete apresentaram a forma crônica. Todos os pacientes apresentaram a forma parenquimatosa. Cerca de 60% dos pacientes provenientes das regiões norte e nordeste de Minas Gerais desenvolveram NPCM. Foi observado o desenvolvimento de NPCM em uma mãe e em seu filho. Os pacientes com NPCM apresentaram perfis demográficos e clínicos similares à descrição da literatura. Quando comparados aos pacientes com PCM, houve diferenças em relação à procedência de tais pacientes e história familiar positiva de PCM. CONCLUSÕES: Os resultados confirmam a importância da avaliação neurológica em pacientes com PCM. Apesar das limitações desse trabalho, as diferenças com relação à procedência dos pacientes e à história familiar apontam para a necessidade de mais estudos para investigar a existência de fatores de susceptibilidade envolvidos no desenvolvimento da NPCM.

Cefepime encephalopathy and normal renal function / Encefalopatia induzida por cefepime em um paciente com função renal normal

BACKGROUND: Several cases of cefepime neurotoxicity have been reported. Herein reported is a case of cephalosporin-associated neurotoxicity in apatient with normal renal function. CASE REPORT: A 64-year-old woman with a history of post-transplantation chronic myeloid leukemia was admittedto hospital due to hyporexia, fever, productive cough and mild dyspnea. Initial blood screen revealed pancytopenia and a normal renal function.Intravenous cefepime was empirically started and after 40 hours the patient developed sudden mental confusion. Neurological examination was normal. Cranial computed tomography and brain magnetic resonance scans were normal. Electroencephalography showed triphasic waves of diffuse slowness without ongoing epileptic activity. Lumbar puncture was normal. Cefepime neurotoxicity was promptly considered and antibiotics were switched to piperacillin and tazobactam. After five days, the patient recovered completely with remission of myoclonus. CONCLUSIONS: Awareness should be given to possible central nervous system complications induced by cefepime, especially in the elderly, even without renal failure

INTRODUÇÃO: Existem vários relatos de casos de toxicidade do sistema nervoso central induzida pelo cefepime. Relata-se um caso de toxicidade do sistema nervoso central associada ao uso de uma cefalosporina em um paciente com função renal normal. RELATO DE CASO: Uma mulher de 64 anos com história de transplante de medula óssea devido a leucemia mielóide crônica foi admitida ao hospital devido a hiporexia, febre, tosse produtiva e dispnéia leve. Os exames laboratoriais de rotina demonstraram pancitopenia e função renal normal. O cefepime intravenoso foi empiricamente iniciado e, após 40 horas da administração, o paciente apresentou quadro súbito de confusão mental. Exame neurológico foi normal, assim como a tomografia computadorizada craniana e a ressonância magnética encefálica. O eletroencefalograma demonstrou ondas trifásicas de lentificação difusa sem evidência de atividade epileptiforme. O líquor estava normal. A toxicidade do sistema nervoso central pelo cefepime foi rapidamente considerada e o antibiótico foi trocado para piperacilina e tazobactan. Após cinco dias, o paciente apresentou recuperação completa com remissão da mioclonia. CONCLUSÃO: Deve-se dar atenção às possíveis complicações do sistema nervoso central induzidas pelo cefepime, especialmente em idosos, mesmo sem insuficiência renal.

Metisergida como profilaxia de migrânea e cefaleia em salvas, e a possível ocorrência de fibrose retroperitoneal: relato de casos / Methysergide as prophylaxis of migraine and cluster headache, and the possible occurrence of retroperitoneal fibrosis: a case report

JUSTIFICATIVA E OBJETIVOS: Metisergida é fármaco de eficácia comprovada na profilaxia tanto da migrânea quanto da cefaleia em salvas, embora possa predispor a fibrose (< 1%). O objetivo deste estudo foi relatar dois casos de cefaleia primária de difícil controle, satisfatoriamente conduzidos com metisergida, que precisou ser interrompida por suspeita de fibrose retroperitoneal (FR). RELATO DOS CASOS: A metisergida foi utilizada, com sucesso, como profilático de migrânea e cefaleia em salvas em paciente de 69 anos, sexo feminino, e de 58 anos, sexo masculino, respectivamente, ambos refratários aos fármacos de primeira e segunda linha. Após 24 meses, no primeiro caso e 30 meses, no segundo, de uso contínuo de metisergida, foram observados sinais e sintomas sugestivos de FR como edema assimétrico de membros inferiores, sem dor, na paciente com migrânea; dor abdominal, disfunção sexual e edema de membros inferiores, no paciente com cefaleia em salvas. Apesar do rastreio inicial negativo para fibrose retroperitoneal feito com ultrassonografia e tomografia computadorizada de abdômen normais, no segundo, como os sinais e sintomas estavam progressivos, optou-se pela suspensão e redução, respectivamente, da metisergida. Houve resolução completa do quadro cerca de uma semana após essa conduta. CONCLUSÃO: A metisergida é boa opção nos casos refratários, mas deve ser utilizada com cautela. Estratégia de descontinuidade do fármaco a cada seis meses, por cerca de 4 a 8 semanas, reduz o risco de ocorrência de FR, assim como observação clínica de sinais e sintomas que sugiram esse efeito colateral.

BACKGROUND AND OBJECTIVES: Methysergide is a drug with proven efficacy to prevent both migraine and cluster headache, although it may predispose to fibrosis (< 1%). This study aimed at reporting two cases of primary and difficult to control headache, satisfactorily treated with methysergide, which had to be withdrawn due to suspicion of retroperitoneal fibrosis (RF). CASE REPORTS: Methysergide was successfully used to prevent migraine and cluster headache in a 69-year old male and in a 58-year old female, respectively, both refractory to first and second line drugs. After 24 months for the first case, and 30 months for the second case, of continuous methysergide, signs and symptoms suggesting RF were observed, such as asymmetric painless lower limbs edema in the migraine patient, and abdominal pain, sexual dysfunction and lower limbs edema in the cluster headache patient. In spite of the early negative screening for retroperitoneal edema made with normal abdominal ultrasound and CT, in the second, since signs and symptoms were progressing, we decided for methysergide withdrawal and decrease, respectively. There has been total resolution of symptoms approximately one week after such approach. CONCLUSION: Methysergide is a good option for refractory cases, but should be used with caution. Withdrawing the drug every six months for approximately 4 to 8 weeks decreases the incidence of RF, in addition to clinical observation of signs and symptoms suggesting this side-effect.

Impact of changes in balance and walking capacity on the quality of life in patients with Parkinson's disease / Impacto das alterações de equilíbrio e da capacidade de marcha na qualidade de vida de pacientes com doença de Parkinson

Parkinson's disease (PD) is characterized by motor symptoms that cause the decline of functional capacity and affect the quality of life (QoL). Objective: To evaluate the impact of changes in balance and walking capacity on the PD. Methods: The instruments used were: Unified Parkinson's Disease Rating Scale (UPDRS), modified Hoehn and Yahr Scale (HY), Schwab and England scale (SE), quality of life questionnaire (PDQ-39), Berg balance Scale (BBS) and six-minute walk test (6MWT). Results: Thirty-six patients with mean disease duration of 7.3 years were assessed. Lower scores on the BBS and shorter distances walked during the 6MWT correlated with a poorer perception of QoL. This correlation occurred at the expense of the mobility and daily living activities domains. Conclusion: Our results indicated that the impairment in balance while performing functional activities and the reduction in walking capacity are important factors that negatively affect the perception of QoL in PD patients.

A doença de Parkinson (DP) é caracterizada por sintomas motores que causam declínio da capacidade funcional e afetam a qualidade de vida (QV). Objetivo: Avaliar o impacto das mudanças no equilíbrio e na capacidade de marcha em doentes com DP. Métodos: Foram utilizados instrumentos específicos para avaliação clínica da DP: Escala Unificada de Avaliação da Doença de Parkinson (UPDRS), Escala de Hoehn e Yahr (HY) modificada, Escala de Schwab e England (SE), questionário de qualidade de vida (PDQ-39), Escala de Equilíbrio de Berg (EEB) e teste de caminhada de seis minutos (TC6M). Resultados: Foram avaliados 36 pacientes, com duração média da doença de 7,3 anos. Menores pontuações na EEB e menores distâncias percorridas durante o TC6M mostraram correlação com pior percepção da QV. Essa correlação ocorreu em detrimento dos domínios de mobilidade e atividades de vida diária. Conclusão: Nossos resultados indicaram que o prejuízo no equilíbrio durante a realização de atividades funcionais e a redução na capacidade de caminhar são fatores importantes que afetam negativamente a percepção da QV em pacientes com DP.

The Pietà study: epidemiological investigation on successful brain aging in Caeté (MG), Brazil. Methods and baseline cohort characteristics / Estudo Pietà: investigação epidemiológica sobre envelhecimento cerebral bem sucedido em Caeté (MG), Brasil. Métodos e características de base da coorte

OBJECTIVES: To present the methods and baseline characteristics of the Pietà study, a population-based survey investigating successful brain aging in the oldest-old. METHOD: The study was conducted in Caeté (MG), Brazil. In 2007, 1,251 individuals aged 75+ years were living in the city and were invited to participate. Participants responded to a general health questionnaire and were submitted to clinical, neurological, cognitive, psychiatric and functional evaluations. A subgroup was submitted to neuropsychological testing, blood tests and magnetic resonance of the skull. Individuals were classified as having cognitive impairment-no dementia, dementia, parkinsonism, psychiatric disorders or successful brain aging. RESULTS: We evaluated 639 individuals (51.1 percent of the target population; 64 percent women), aged 81.4±5.2 years and with 2.7±2.6 years of schooling. Almost 30 percent of the elderly were illiterates and 82.1 percent belonged to middle/middle-low socioeconomic levels. Almost 50 percent were widows, but only 14.3 percent were living alone. CONCLUSION: The Pietà cohort is representative of the oldest-old Brazilian population. We believe the results of the study may contribute to increase our knowledge about healthy and pathological brain aging in the oldest-old.

Psychiatric disorders in myasthenia gravis / Transtornos psiquiátricos na miastenia gravis

OBJECTIVE: To investigate the prevalence of psychiatric disorders in patients with myasthenia gravis (MG). METHOD: Forty-one patients with MG answered to a structured psychiatric interview (MINI-Plus). RESULTS: Eleven (26.1 percent) patients were diagnosed with a depressive disorder and 19 (46.3 percent) were diagnosed with an anxiety disorder. Patients with dysthymia were older (p=0.029) and had longer disease duration (p=0.006). Patients with social phobia also had longer disease duration (p=0.039). CONCLUSION: Psychiatric disorders in MG are common, especially depressive and anxiety disorders.

Pacientes com distimia eram mais velhos (p=0,029) e tinham maior tempo de doença (p=0,006). Os pacientes com fobia social também tiveram maior tempo de doença (p=0,039). CONCLUSÃO: Transtornos psiquiátricos na MG são bastante comuns, principalmente transtornos depressivos e de ansiedade.

Soluble inflammatory markers as predictors of virological response in patients with chronic hepatitis C virus infection treated with interferon-α plus ribavirin

The host immune response plays an important role in viral clearance in patients who are chronically infected with hepatitis C virus (HCV) and are treated with interferon and ribavirin. Activation of the immune system involves the release of pro and anti-inflammatory molecules that can be measured in plasma samples. The present study aimed to evaluate the association between pretreatment plasma levels of chemokines and soluble tumor necrosis factor receptors (sTNF-R) and the virological response in treated patients with chronic hepatitis C infection. Forty-one chronically-infected HCV patients that were being treated with interferon-α (IFN-α) plus ribavirin were included in the study. Socio-demographic, clinical and laboratory data were collected and pretreatment plasma levels of chemokine CCL2, CCL3, CCL11, CCL24, chemokine CXCL9, CXCL10, sTNF-R1 and sTNF-R2 were measured. The virological response was assessed at treatment week 12, at the end of treatment and 24 weeks after treatment. Pretreatment CXCL10 levels were significantly higher in patients without an early virological response (EVR) or sustained virological response (SVR) compared to responders [512.9 pg/mL vs. 179.1 pg/mL (p = 0.011) and 289.9 pg/mL vs. 142.7 pg/mL (p = 0.045), respectively]. The accuracy of CXCL10 as a predictor of the absence of EVR and SVR was 0.79 [confidence interval (CI) 95 percent: 0.59-0.99] and 0.69 (CI 95 percent: 0.51-0.87), respectively. Pretreatment plasma levels of the other soluble inflammatory markers evaluated were not associated with a treatment response. Pretreatment CXCL10 levels were predictive of both EVR and SVR to IFN-α and ribavirin and may be useful in the evaluation of candidates for therapy.

Hyaluronic acid in the evaluation of liver fibrosis in patients with hepatitis C on haemodialysis

BACKGROUND: This study evaluated the role of HA as a marker of liver fibrosis in patients with hepatitis C on haemodialysis. METHODS: This is a cross-sectional study in which 52 patients were divided into two groups: Group 1: patients with hepatitis C and end-stage renal disease (ESRD) undergoing haemodialysis (n = 23); and Group 2: patients with hepatitis C without ESRD (n = 29). Plasma levels of HA were associated with histological data of the samples obtained by liver biopsy and classified by METAVIR group scoring system. RESULTS: Higher plasma levels were significantly correlated to significant liver fibrosis (METAVIR > F2). In Group 1, the HA cutoff to discriminate significant fibrosis was 984.8 ng/mL, with accuracy, sensitivity and specificity of 80.8 percent, 83.0 percent, and 70.0 percent, respectively. In Group 2, the HA cutoff was 222.3 ng/mL, with accuracy, sensitivity and specificity of 74.5 percent, 70.0 percent, and 94.0 percent, respectively. CONCLUSION: HA was an accurate noninvasive marker in predicting significant fibrosis in patients with hepatitis C on haemodialysis.
