Neurología hospitalaria y COVID-19: serie de 96 pacientes evaluados en un hospital universitario / Neurology and COVID-19: Case Series of Neurological Complications in 96 patients Admitted at a University Hospital

Background: There are multisystemic consequences secondary to SARS- CoV-2 infection. Aim: To characterize neurological complications in patients admitted due to SARS-CoV-2 infection. Methods: Review of medical records of patients aged over 15 years with COVID-19 evaluated by the neurology team between April and August 2020 at a university hospital. Severity of the infection, referral reasons, neurological diagnoses and laboratory results were registered. The diagnoses were defined by consensus among the members of the hospital neurology group. Cerebrovascular and inflammatory diseases of the central and peripheral nervous system were defined as "probably associated" or "possibly associated" to COVID-19. Results: Ninety-six patients had at least 1 new neu- rological complication. 74% were admitted due to pneumonia and 20% due to a neurological disease. The most common reasons for neurological referral were impaired consciousness (39%), focal neurological deficit (24%), headache (9%) and seizures (5%). The most relevant neurological diagnoses were delirium in 48 patients, stroke in 24, critical illness polyneuropathy and myopathy in 17, seizures in 14, brachial plexopathy in 3, compressive neuropathies in 5, encephalitis in 1, possible vasculitis in 1 and Guillain-Barré syndrome in 1. Stroke and epilepsy were associated with increased length of hospital stay, but without differences in mortality. Conclusions: The spectrum of neurological complications of COVID-19 is wide. There are clinical entities typical of critically ill patients and also diseases associated directly and indirectly with the SARS-CoV2 infection.

Multimorbidity and associated outcomes among older adult inpatients with neurological disorders / Multimorbidade e desfechos associados entre idosos hospitalizados com doenças neurológicas

ABSTRACT Background: Multimorbidity is common among adults and associated with socioeconomic deprivation, polypharmacy, poor quality of life, functional impairment, and mortality. Objectives: To identify the frequency of multimorbidity among older adults inpatients with neurological disorders (NDs), stratify clusters of chronic comorbidities associated with NDs in degrees, and verify whether multimorbidity was associated with demographic data, readmission, long length of hospital stay (LOS), and hospital mortality in this population. Methods: We enrolled patients aged ≥60 years successively admitted to a tertiary medical center with NDs between January 1, 2009, and December 31, 2010. Results: Overall, 1,154 NDs and 2,679 comorbidities were identified among 798 inpatients aged ≥60 years (mean: 75.76±9.12). Women comprised 435 (54.51%) of patients. Multimorbidity was detected in 92.61% (739) of patients, with a mean of 3.88±1.67 (median: 4.0), ranging from 2 to 10 chronic diseases. Patients with epilepsy, dementia, and movement disorders had the highest degrees of clusters of chronic morbidities (>50% of them with ≥5 chronic disorders), followed by those with cerebrovascular and neuromuscular disorders. Multimorbidity was associated with long LOS (p<0.001) and readmission (p=0.039), but not with hospital mortality (p=0.999). Conclusions: Multimorbidity was preponderant among older adults inpatients with NDs, and NDs had a high degree of associated chronic comorbidities. Multimorbidity, but not isolated NDs, was associated with readmission and long LOS. These results support ward-based, neurohospitalist-directed, interdisciplinary care for older adults inpatients with NDs to face multimorbidity.

RESUMO Introdução: A multimorbidade é comum entre idosos e está associada a privação socioeconômica, polifarmácia, má qualidade de vida, déficit funcional e mortalidade. Objetivos: Identificar a frequência da multimorbidade entre pacientes idosos hospitalizados com doenças neurológicas (DN), estratificar combinações de comorbidades crônicas associadas às DN em graus e verificar se a multimorbidade foi associada a dados demográficos, readmissão, longo tempo de internação (TDI) e mortalidade hospitalar nessa população. Métodos: Foram incluídos pacientes com ≥60 anos sucessivamente admitidos com DN em um centro médico terciário entre 1º de janeiro de 2009 e 31 de dezembro de 2010. Resultados: Um total de 1.154 DN e 2.679 comorbidades foram identificados entre 798 pacientes com idade ≥60 anos (média: 75,76±9,12). Mulheres representaram 435 (54,51%) dos pacientes. A multimorbidade foi detectada em 92,61% (739) dos pacientes (média de 3,88±1,67; mediana de 4), variando de 2 a 10 doenças crônicas. Pacientes com epilepsia, demência e distúrbios do movimento apresentaram os maiores graus de morbidades crônicas (>50% deles com ≥5 doenças crônicas), seguidos por doenças cerebrovasculares e neuromusculares. A multimorbidade foi associada com longo TDI (p<0,001) e readmissão (p=0,039), mas não com mortalidade hospitalar (p=0,999). Conclusões: A multimorbidade foi preponderante entre os pacientes idosos internados com DN, as quais tiveram altos graus de comorbidades crônicas. A multimorbidade, mas não as DN isoladas, foi associada a readmissões e longo TDI. Esses resultados respaldam uma assistência interdisciplinar para idosos hospitalizados com DN em enfermarias lideradas por neurologistas hospitalistas para enfrentar a multimorbidade.

Complicações neurológicas associadas ao SARS-CoV-2 (COVID-19) no Brasil: organização do grupo NEUROCOVID-RIO e achados preliminares / Neurological complications associated with SARS-CoV-2 (COVID-19) in Brazil: organization of the NEUROCOVID-RIO group and preliminary findings

We live in moments of uncertainty due to the serious pandemic promoted by the Sars-CoV-2 virus. Furthermore, in our country, other viruses are there, such as H1N1, Dengue, Zika, Chikungunya, Measles, Yellow Fever, which often leave us perplexed by the differential diagnosis of different neurological syndromes that may, eventually, be associated. We created the NEUROCOVID-RIO Group comprising currently 44 health experts from several areas of the neurological sciences from different hospitals and laboratories from various institutions, including public and private universities. A database in which mathematical instruments are applied, including artificial intelligence, was organized. Preliminary findings show that well defined neurological syndromes seems to be more associated to Zika and Chikungunia viruses than with Sars-Cov-2.

Los Trastornos Paroxísticos No Epilépticos (TPNE), son diagnóstico diferencial de crisis epilépticas. En Chile no existen reportes de frecuencia. OBJETIVO: Determinar frecuencia de TPNE en pacientes derivados por sospecha de epilepsia a Unidad de Electroencefalografía, Hospital Roberto del Río. METODOLOGÍA: Estudio observacional, transversal. Se revisó registros clínicos de pacientes derivados por sospecha de epilepsia(2012- 2014). Inclusión: paciente con TPNE, >1 mes, sin epilepsia previa. Caracterización: sexo, edad, tipo/subtipo TPNE, comorbilidades, electroencefalograma (EEG), uso fármaco antiepiléptico (FAE). Aprobado por comité de ética. RESULTADOS: Derivados 913 pacientes por sospecha de epilepsia. 36% TPNE (2,3% con epilepsia concomitante), 22% epilepsia aislada. TPNE más frecuente: escolares (31%), adolescentes (29%), femenino (52%). 30,1% hipoxia cerebral (síncope, Espasmo Sollozo); 22,4% trastornos del comportamiento (Descontrol Episódico, Crisis Psicógena no Epiléptica). 32,8% con comorbilidades no epilépticas (Trastornos psiquiátricos/neurodesarrollo). 4,3 % recibieron FAE. CONCLUSIONES: La frecuencia de TPNE en niños/adolescentes supera a la de epilepsia. Es fundamental evaluación multidisciplinaria.

Paroxysmal non-epileptic events (PNE) are differential diagnosis of epileptic seizures. In Chile, there are no reports on its frequency. OBJECTIVE: To determine the frequency of PNE in patients referred for suspicion of epilepsy to the Electroencephalography Unit of Roberto del Río Hospital. METHODOLOGY: Observational, cross-sectional study. Clinical records of patients referred for suspicion of epilepsy (2012-2014) were reviewed. Inclusion: Patient with PNE, >1 month, without previous epilepsy. Characterization: gender, age, PNE type/subtype, comorbidities, electroencephalogram, use of antiepileptic drug (AED). Approved by the ethics committee. RESULTS: 913 patients were referred for suspected epilepsy: 36% PNE (2,3% with concomitant epilepsy), 22% isolated epilepsy. PNE were more frequent in children (31%) adolescents (29%), and in females (52%). 30.1% Cerebral hypoxia (syncope, breathholding-spells); 22,4% Behavioral disorders (Episodic loss of control, Non-Epileptic Psychogenic Seizures). 32.8% non-epileptic comorbidities (Psychiatric/ neurodevelopmental disorders). 4.3% received AEDs. CONCLUSIONS: The frequency of PNE in children and adolescents exceeds that of epilepsy. A multidisciplinary medical evaluation is of the outmost importance. Keywords: Paroxysmal Non-Epileptic Disorder, Non-epileptic episodes, Epilepsy.

Riesgos prenatales, perinatales y neonatales asociados a signos neurológicos blandos / Prenatal, perinatal and neonatal risks associated with soft neurological signs

Introducción: Los signos neurológicos blandos se han asociado con dificultades motoras, alteraciones comportamentales menores e incluso como factores de vulnerabilidad para la aparición de afecciones como, esquizofrenia, trastorno de déficit de atención e hiperactividad, trastorno disocial y episodios psicóticos. Aunque la investigación sobre los signos ha venido aumentando, no se tiene claridad sobre qué puede predisponer su aparición. Objetivo: Describir la asociación entre factores de riesgo prenatales, perinatales y neonatales y la aparición de los signos neurológicos blandos en niños con estos factores riesgo y en niños sin ellos. Métodos: Estudio de tipo descriptivo comparativo, de corte transversal, con diseño no experimental. La población en estudio se conformó por 550 niños y niñas, con edades entre seis y ocho años organizados. en cuatro grupos: los que presentaban riesgos prenatales, perinatales, neonatales, y el grupo que no presentaba ningún riesgo. Las aplicaciones se llevaron a cabo durante el primer semestre de 2017. Los datos se tomaron de las historias clínicas y los. signos neurológicos blandos se evaluaron a través del apartado de la Evaluación Neuropsicológica Infantil. Resultados: La mayoría de los signos neurológicos blandos presentaron diferencias significativas y valores altos en la comparación de los rendimientos en cada uno de los grupos con riesgo. Conclusiones: la presencia de riesgos prenatales, perinatales y neonatales producen una serie de alteraciones en el desarrollo del niño que se van acumulando y pueden estar asociados con la aparición de los signos neurológicos blandos(AU)

Introduction: The soft neurological signs have been associated with motor difficulties, lower behavioural alterations and even with vulnerability factors for the appearance of conditions such as schizophrenia, attention deficit disorder and hyperactivity, disocial disorder and psychotic episodes. Although research on the signs has been increasing, it is not clear what may predispose their appearance. Objective: To describe the association between prenatal, perinatal and neonatal risk factors and the appearance of the soft neurological signs in children with these risk factors and in children without them. Methods: Descriptive, comparative, cross-sectional non-experimental design´s study. The study´s population was formed by 550 boys and girls between the ages of six and eight years organized in four groups: with prenatal risks, with perinatal risks, with neonatal risks, and the group that did not present any risks. The tests were carried out during the first semester of 2017. The data were taken from the medical records and the soft neurological signs were evaluated through the item called Neuropsychological Assessment of Children. Results: Most of the soft neurological signs showed significant differences and high values in the performance comparison in each of the groups with risks. Conclusions: The presence of prenatal, perinatal and neonatal risks produce a series of alterations in the development of the child that are accumulated and may be associated with the appearance of the soft neurological signs(AU)

Demographic characteristics and neurological comorbidity of patients with COVID-19

SUMMARY ABSTRACT The COVID-19 infection that started in the Wuhan Province of the People's Republic of China and has now spread throughout the world is not limited to the respiratory system, but also causes other systemic symptoms through viremia. Recent data show that the central and peripheral nervous system involvement is particularly substantial. Thus, the present study aims to investigate the current neurological comorbidities and symptoms of patients with COVID-19 who were followed up by our clinic physicians.

RESUMO RESUMO A infecção de COVID-19 que começou na província de Wuhan, na República Popular da China, e já se espalhou por todo o mundo não se limita ao sistema respiratório, mas também causa outros sintomas sistêmicos através de viremia. Dados recentes mostram que seus efeitos no sistema nervoso central e periférico são particularmente significativos. Assim, o presente estudo tem como objetivo investigar as atuais comorbidades e sintomas neurológicos de pacientes com COVID-19 que foram acompanhados pelos médicos da nossa clínica.

Predictors of readmission and long length of stay in elders admitted with neurological disorders in a tertiary center: a real-world investigation / Preditores de readmissão hospitalar e de longo tempo de internação em idosos admitidos com doenças neurológicas em centro terciário: uma investigação no mundo real

ABSTRACT Hospital readmission and long length of stay (LOS) increase morbidity and hospital mortality and are associated with excessive costs to health systems. Objective: This study aimed to identify predictors of hospital readmission and long LOS among elders with neurological disorders (NDs). Methods: Patients ≥ 60 years of age admitted to the hospital between January 1, 2009, and December 31, 2010, with acute NDs, chronic NDs as underpinnings of acute clinical disorders, and neurological complications of other diseases were studied. We analyzed demographic factors, NDs, and comorbidities as independent predictors of readmission and long LOS (≥ 9 days). Logistic regression was performed for multivariate analysis. Results: Overall, 1,154 NDs and 2,679 comorbidities were identified among 798 inpatients aged ≥ 60 years (mean 75.8 ± 9.1). Of the patients, 54.5% were female. Patient readmissions were 251(31%) and 409 patients (51%) had an LOS ≥ 9 days (95% confidence interval 48%-55%). We found no predictors for readmission. Low socioeconomic class (p = 0.001), respiratory disorder (p < 0.001), infection (p < 0.001), genitourinary disorder (p < 0.033), and arterial hypertension (p = 0.002) were predictors of long LOS. Identified risks of long LOS explained 22% of predictors. Conclusions: Identifying risk factors for patient readmission are challenges for neurology teams and health system stakeholders. As low socioeconomic class and four comorbidities, but no NDs, were identified as predictors for long LOS, we recommend studying patient multimorbidity as well as functional and cognitive scores to determine whether they improve the risk model of long LOS in this population.

RESUMO Readmissão hospitalar e tempo longo de internação aumentam a morbidade, a mortalidade hospitalar e estão associados a custos excessivos para os sistemas de saúde. Objetivo: Este estudo almejou identificar preditores de readmissões hospitalares e longo tempo de internação (TDI) entre idosos com doenças neurológicas (DN). Métodos: Pacientes de idade ≥ 60 anos admitidos no hospital entre 1 de janeiro de 2009 e 31 de dezembro de 2010 com DN aguda, DN crônica subjacente a transtorno clínico agudo e complicações neurológicas de outras doenças foram estudados. Nos analisamos fatores demográficos, DN e comorbidades como preditores independentes de readmissão hospitalar e TDI (≥ 9 dias). Utilizamos regressão logística para analise multivariada. Resultados: Um total de 1154 DN e 2679 comorbidades foram identificadas entre 798 pacientes com idade ≥ 60 anos (media 75.8 ± 9.1). Desses pacientes 54.5% foram mulheres. Foram 251(31%) readmissões de pacientes e 409 (51%) dos pacientes tiveram um TDI≥9 dias (intervalo de confiança 95%, 48%-55%). Não encontramos preditores para readmissões. Baixa classe social (p = 0,001), distúrbio respiratório (p < 0,001), infecção (p < 0,001), distúrbio genito-urinário (p = 0,033) e hipertensão arterial (p = 0,002) foram os preditores de longo tempo de internação. Esses fatores de risco compõem 22% dos preditores para longo TDI. Conclusões: A identificação de fatores de risco para readmissão hospitalar é um desafio para equipes neurológicas e gestores dos sistemas de saúde. Conquanto baixa classe social e 4 comorbidades, todavia nenhuma DN, foram identificadas como preditoras para longo TDI nós recomendamos investigar multimorbidade, escores funcionais e cognitivos para saber se eles melhoram o modelo de risco para longo TDI nesta população.

Abstract INTRODUCTION Dengue has affected Rio de Janeiro City since the 1980s. The sequential Zika and chikungunya virus introductions during 2015 aggravated the health scenario, with 97,241 cases of arboviral diseases reported in 2015-2016, some with neurological disorders. METHODS Arbovirus-related neurologic cases were descriptively analyzed, including neurological syndromes and laboratory results. RESULTS In total, 112 cases with non-congenital neurologic manifestations (Guillain-Barré syndrome, 64.3%; meningoencephalitis, 24.1%; acute demyelinating encephalomyelitis, 8%) were arbovirus-related; 43.7% were laboratory-confirmed, of which 57.1% were chikungunya-positive. CONCLUSIONS Emerging arbovirus infections brought opportunities to study atypical, severe manifestations. Surveillance responses optimized case identification and better clinical approaches.

Doenças neurológicas em gatos: 155 casos / Neurological diseases in cats: 155 cases

Foi realizado um estudo epidemiológico retrospectivo de gatos com doenças neurológicas atendidos em um Hospital Veterinário Universitário entre 2001 e 2014. O objetivo foi identificar e caracterizar a idade, o sexo, a raça, as doenças neurológicas e classificá-las de acordo com a região anatômica e o acrônimo DINAMIT-V. Foram observados 155 gatos com doenças neurológicas em 13 anos, sendo o diagnóstico confirmado em 112 gatos (72,2%) e presuntivo em 43 (27,8%). Gatos sem raça definida (77,9%) foram os mais comuns, seguido de gatos da raça persa e siamesa. Os locais mais afetados foram medula espinhal entre T3-L3 (28,4%) e tálamo-córtex (24,5%). A maioria dos gatos (43,9%) foi diagnosticada com doença traumática, principalmente trauma de medula espinhal, seguida de doença inflamatória/infecciosa (33,5%). Pode se concluir que a maior prevalência das doenças neurológicas de gatos envolve a medula espinhal e o tálamo-córtex, sendo as traumáticas as mais frequentes. Os dados obtidos podem auxiliar em futuros estudos sobre a frequência e a distribuição das principais doenças neurológicas em gatos.(AU)

A retrospective epidemiological study on neurological disease of cats was performed using data from cats admitted to a Veterinary Teaching Hospital from 2001 to 2014. The aim the study was to determine the age, sex race, and type of neurological disease affecting cats and identify these diseases according to the anatomical region and disease classes, specified under the acronym DINAMIT-V. One hundred and fifty five cats with neurological disease were observed during 13 years; the diagnosis was confirmed in 112 (72.2%) and was presumptive in 43 (27.8%). Mixed breed cats (77.9%) were the most commonly affected, followed by Persian and Siamese cats. The most affected anatomic sites were segments T3-L3 of the spinal cord (28.4%) and thalamic-cortical area (24.5%). Most cats (43.9%), were diagnosed with trauma, mainly spinal cord trauma, followed by inflammatory/infectious disease (33.5%). It is concluded that the neurological disorders in cats have higher prevalence in the spinal cord and thalamic-cortical areas and that the most frequent class of disease is trauma. Data obtained may assist future studies regarding neurological diseases in cats.(AU)

Uso de drogas de diseño en fiestas electrónicas: aspectos clínicos, neuropsiquiátricos, epidemiológicos y de intervención prehospitalaria / Use of designer drugs in electronic parties: clinical, neuropsychiatric, epidemiological and prehospital intervention aspects

Introducción: Las llamadas "fiestas electrónicas" permitieron la generalización del uso de drogas de diseño (DdD) para disminuir el cansancio, las inhibiciones y aumentar la empatía entre los asistentes. Objetivo: Presentar los resultados de prevalencia, aspectos neuropsiquiátricos, clínicos y epidemiológicos del uso de DdD en fiestas electrónicas. Material y método: Realizamos un estudio de campo, observacional y transversal, mediante encuesta estandarizada, normatizada y anónima para consignar parámetros clínicos y neuropsiquiátricos en 138 asistentes a fiestas electrónicas que mediante demanda espontánea o requerida por terceros fueron evaluados por médicos y refirieron consumo de DdD. Se aplicaron parámetros estadísticos y se cumplieron normas éticas. Resultados: Objetivamos un alto consumo de alcohol, con alta prevalencia de uso comórbido con otras sustancias de diseño como el éxtasis y GHB. Los consumidores de GHB presentaron disminución de parámetros clínicos con un síndrome inhibitorio, en contraste con los valores aumentados en usuarios de éxtasis. Conclusión: La diferencia en las manifestaciones clínico-neuropsiquiátricas tienen sustento en aspectos neurobiológicos del mecanismo de acción y condicionan el tratamiento prehospitalario.

Introduction: The so-called "electronic parties" allowed the widespread use of designer drugs (DOD) to reduce fatigue, inhibitions and increase empathy among participants. Objective: To present the results of prevalence, neuropsychiatric, clinical and epidemiological aspects of the use of DoD in electronic parties. Material and Methods: We conducted a field study, observational and transversal, through standardized, Normatized and anonymous survey to record clinical and neuropsychiatric parameters 138 attendees electronic parties that by spontaneous or required by third application were evaluated by physicians and reported consumption of DOD. Statistical parameters were applied and ethical standards were met. Results: We objectify a high consumption of alcohol, with high prevalence of comorbid use design with other substances like ecstasy and GHB. GHB consumers had decreased clinical parameters with an inhibitory syndrome, in contrast to the values increased in users of ecstasy. Conclusions The difference in clinical and neuropsychiatric manifestations have support in neurobiological aspects of the mechanism of action and determine the prehospital treatment.

Complex chronic conditions in children and adolescents: hospitalizations in Brazil, 2013 / Condições crônicas complexas em crianças e adolescents: internações no Brasil, 2013

Abstract This article aims to estimate the extent of hospitalizations for complex chronic conditions in Brazil. Data from the Hospital Information System for 2013 were compiled according to the International Classification of Diseases 10th Revision. Hospitalization rates were estimated according to region, sex, age and disease chapter, taking into account the 2012 population as a reference, as well the percentage of highly complex procedures and mortality rates. Public hospitals treated 190,000 inpatients in 2013. The rate was highest among the population in the South of Brazil, those who were male and children under the age of one. The rate was lowest among the population in the North, females and children aged between 10 and 14years. The mean duration of hospitalization was six days, the percentage of highly complex procedures was 13.5% and the mortality rate was 1.3%. The three most common causes for hospitalizations were diseases of the respiratory system, neoplasms and diseases of the nervous system. The incidence of complex chronic conditions is 331 inwards per 100,000 children and adolescents in Brazil, with an estimate of 240,000 children and adolescents hospitalized. This panorama points to the problem as an emergent public health issue in Brazil.

Resumo O objetivo deste artigo é estimar a magnitude das internações por doenças crônicas complexas no Brasil. Dados do Sistema de Informações Hospitalares referentes a 2013 foram compilados de acordo com a Classificação Internacional de Doenças 10ª revisão. Taxas de internação foram estimadas de acordo com a região, sexo, idade e doença, tendo como referência a população de 2012, bem como o percentual de procedimentos de alta complexidade e as taxas de mortalidade. Hospitais públicos tiveram 190.000 pacientes internados em 2013. A taxa foi maior entre a população do Sul do Brasil, entre homens e crianças menores de um ano de idade. A taxa foi menor entre a população do Norte, entre mulheres e crianças de 10 a 14 anos de idade. A duração média de internação foi de seis dias, a porcentagem de procedimentos de alta complexidade foi de 13,5% e a taxa de mortalidade foi de 1,3%. As três causas mais comuns para internações foram as doenças do sistema respiratório, neoplasias e doenças do sistema nervoso. A incidência de hospitalização por doenças crônicas complexas foi 331 para 100.000 crianças e adolescentes no Brasil, com uma estimativa de 240.000 crianças e adolescentes hospitalizados. Esse panorama aponta para as doenças crônicas complexas como problema emergente em saúde pública no Brasil.

Psicosis de Korsakoff, a propósito de un caso interesante / Korsakoff's psychosis, about an interesting case

La psicosis de Korsakoff (PK) es una de las causas más frecuentes de amnesia. Se caracteriza por confusión mental, deterioro de la memoria reciente y confabulación. Se presenta el caso de un paciente masculino de 53 años de edad, fumador de un paquete al día, durante más de 35 años, bebedor de riesgo, con antecedentes de hipertensión arterial e hipercolesterolemia. Se diagnosticó como psicosis de Korsakoff debido al déficit de tiamina o vitamina B1. La psicosis de Korsakoff es un síndrome amnésico que puede presentarse precedido o no de encefalopatía de Wernicke (EW), por lo que se diagnostican menos casos de los que en realidad existen. Por ello, es un problema frecuentemente infradiagnosticado en los centros de salud lo que resulta interesante el conocimiento de esta patología (AU).

Korsakoff psychosis is one of the most frequent causes of amnesia. It is characterized by mental confusion, impairment of the recent memory and confabulation. It is presented the case of a male patient, aged 53 years, who smoked 1 packet of cigarettes a day during more than 35 years, risk drinker with antecedents of arterial hypertension and hypercholesterolemia. He was diagnosed as Korsakoff psychosis due to the thiamine or B1 vitamin deficit. Korsakoff psychosis is an amnesic syndrome that may be preceded or not by Wernicke encephalopathy, so there are diagnosed fewer cases than those truly existing. That is why it is a problem frequently underdiagnosed in health care institutions, making interesting this disease´s knowledge (AU).

Neurological manifestations of Chikungunya and Zika infections / Manifestações neurológicas das infecções pelos vírus Zika e Chikungunya

ABSTRACT 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.

RESUMO 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.

Deep Vein Thrombosis in the Lower Extremities in Comatose Elderly Patients with Acute Neurological Diseases

PURPOSE: Comatose elderly patients with acute neurological illness have a great risk of deep vein thrombosis (DVT). In this study, the incidence of DVT and the effectiveness of early initiation of treatment were evaluated in those patients. MATERIALS AND METHODS: Total 323 patients were admitted to our ward due to neurological diseases in one year, and 43 patients, whose Glasgow Coma Scale was or =60 years, were included in this study. D-dimer was measured on admission and day 7, and lower-extremity ultrasonography was performed on day 7. When DVT was positive, heparin treatment was initiated, and further evaluation of pulmonary embolism (PE) was conducted. Vena cava filter protection was inserted in PE-positive patients. Incidence of DVT and PE, alteration of D-dimer value, and effect of heparin treatment were analyzed. RESULTS: DVT was positive in 19 (44.2%) patients, and PE was in 4 (9.3%). D-dimer was significantly higher in DVT-positive group on day 7 (p<0.01). No DVT were identified in patients with ischemic disease, while 66.7% of intracerebral hemorrhage and 53.3% of brain contusion patients were DVT positive. Surgery was a definite risk factor for DVT, with an odds ratio of 5.25. DVT and PE disappeared by treatment in all cases, and no patients were succumbed to the thrombosis. CONCLUSION: Patients with hemorrhagic diseases or who undergo operation possess high risk of DVT, and initiation of heparin treatment in 7 days after admission is an effective prophylaxis for DVT in comatose elderly patients without causing bleeding.

Severe root resorption resulting from orthodontic treatment: Prevalence and risk factors

OBJECTIVE: To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. METHODS: A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated by means of the Standard Edgewise technique. Two examiners measured and defined root resorption according to the index proposed by Levander et al. The degree of external apical root resorption was registered defining resorption in four degrees of severity. To assess intra and inter-rater reproducibility, kappa coefficient was used. Chi-square test was used to assess the relationship between the amount of root resorption and patient's sex, dental arch (maxillary or mandibular), treatment with or without extractions, treatment duration, root apex stage (open or closed), root shape, as well as overjet and overbite at treatment onset. RESULTS: Maxillary central incisors had the highest percentage of severe root resorption, followed by maxillary lateral incisors and mandibular lateral incisors. Out of 959 teeth, 28 (2.9%) presented severe root resorption. The following risk factors were observed: anterior maxillary teeth, overjet greater than or equal to 5 mm at treatment onset, treatment with extractions, prolonged therapy, and degree of apex formation at treatment onset. CONCLUSION: This study showed that care must be taken in orthodontic treatment involving extractions, great retraction of maxillary incisors, prolonged therapy, and/or completely formed apex at orthodontic treatment onset. .

OBJETIVO: avaliar a prevalência de reabsorções radiculares externas severas e identificar prováveis fatores de risco decorrentes do tratamento ortodôntico. MÉTODOS: utilizou-se uma amostra selecionada aleatoriamente, composta de radiografias periapicais de incisivos superiores e inferiores, obtidas no mesmo centro radiológico, de pré- e pós-tratamento ortodôntico ativo, de 129 pacientes, de ambos os sexos, tratados por meio da técnica Edgewise Standard. Dois examinadores mensuraram e definiram a reabsorção radicular de acordo com índice proposto por Levander et al., e o grau de reabsorção foi registrado, definindo a reabsorção em quatro graus de severidade. Para avaliar a reprodutibilidade intra- e interexaminadores, adotou-se o índice de coeficiente kappa ponderado. O teste chi-quadrado (χ2) foi adotado para avaliar a relação entre a quantidade de reabsorção radicular e o sexo dos pacientes, arcada dentária (superior ou inferior), tratamentos com ou sem extrações, duração do tratamento, forma radicular, estágio do ápice radicular (aberto ou fechado), overjet e overbite no início do tratamento. RESULTADOS: os incisivos centrais superiores apresentaram a maior porcentagem de reabsorção radicular severa, seguidos dos incisivos laterais superiores e dos incisivos laterais inferiores. Entre 959 dentes avaliados, 28 (2,9%) apresentaram reabsorção radicular severa. Os fatores de risco relacionados foram: dentes localizados na região anterossuperior, overjet maior ou igual a 5mm ao início do tratamento, tratamentos envolvendo extrações dentárias, tempo prolongado de terapia e formação radicular completa à época do início do tratamento ortodôntico. CONCLUSÃO: o estudo demonstrou que cuidados devem ser tomados em tratamentos ortodônticos envolvendo extrações, com grande retração de incisivos superiores, tratamentos prolongados e/ou ápice radicular completamente formado no início da terapia ortodôntica. .

Pró-calcitonina como biomarcador inflamatório e prognóstico de mortalidade à admissão na unidade de terapia intensiva: experiência de um hospital universitário / Procalcitonin as an inflammatory and prognostic biomarker of mortality at intensive care unit admission: experience at an university hospital

Introdução: A Pró-calcitonina (PCT) é um dos principais biomarcadores inflamatórios a ser avaliado no paciente critico. Seu papel discriminatório entre etiologias bacterianas e virais, bem como no acompanhamento do tratamento anti-infeccioso é bem estabelecido. O objetivo deste estudo foi avaliar se os níveis séricos de PCT na admissão em UTI eram preditores de mortalidade em pacientes adultos. Métodos: Estudo de coorte histórica. Foram avaliados os prontuários de pacientes consecutivos admitidos na UTI Geral de adultos de um Hospital Universitário, com diferentes diagnósticos etiológicos. Foi acompanhado o desfecho de saída (mortalidade), e comparado com outros marcadores inflamatórios e de prognóstico. Resultados: Incluídos 108 pacientes. Nos pacientes com sepse na admissão, os níveis de PCT foram significativamente maiores. Em todos os grupos, houve tendência a valores maiores dos níveis de PCT entre os pacientes que evoluíram para o óbito na UTI. Valores acima de 3,0 ng/ml foram preditores de mortalidade. Conclusões: Níveis séricos elevados de PCT na admissão em UTI, além de auxílio discriminatório de infecção e sepse, podem ser preditivos de mortalidade (AU)

Introduction: Procalcitonin (PCT) is one of the main inflammatory biomarkers to be evaluated in critically ill patients. Its discriminatory role among bacterial and viral etiologies, as well as in the monitoring of anti-infective treatment, is well established. The aim of this study was to evaluate whether serum PCT levels at admission to ICU were predictors of mortality in adult patients. Methods: A historical cohort study. The medical records of consecutive patients with different etiological diagnoses admitted to the General ICU of a University Hospital were assessed. The outcome (mortality) was accompanied and compared with other inflammatory and prognostic markers. Results: The study comprised 108 patients. In patients with sepsis on admission , PCT levels were signifi cantly higher. In all groups, there was a trend to higher levels of PCT in patients who eventually died in ICU. Values above 3.0 ng/ml were predictors of mortality. Conclusions: Elevated serum PCT levels on ICU admission, besides the discriminatory aid of infection and sepsis, may be predictive of mortality (AU)

Efectos auditivos y neuropsicológicos por exposición a ruido ambiental en escolares, en una localidad de Bogotá, 2010 / The auditory and neuropsychological effects of school children's exposure to environmental noise in a locality in Bogotá, 2010

Objetivo Evaluar el efecto que ejerce el ruido ambiental en la salud auditiva, la aparición de síntomas neuropsicológicos, el desarrollo de actividades educativas y el descanso en estudiantes de una localidad en Bogotá. Metodología Estudio transversal de prevalencia en niños y adolescentes (n=581) de 10-17 años en dos instituciones educativas distritales definidas como de mayor exposición (>65dB) y de menor exposición (<65dB) según el mapa de ruido ambiental de la localidad, clasificación verificada posteriormente. Se aplicó una encuesta de antecedentes de salud, percepción de la exposición a ruido, hábitos relacionados con salud auditiva y una audiometría tonal liminal de la vía aérea, usando criterios recomendados en la guía GATI-HNIR. Resultados El colegio más expuesto excedía la normatividad para la zona de tranquilidad (7/8 mediciones), los niveles de las dos instituciones sobrepasan la recomendación de la OMS (15/16 mediciones). El 14,8 % de los estudiantes presentaban algún grado de Hipoacusia, no se identificaron diferencias según exposición, sin embargo, al comparar los promedios de umbral auditivo, fueron mayores en el grupo de mayor exposición. Se encontró más prevalencia de hipoacusia y síntomas neuropsicológicos en la jornada mañana, y del reporte de síntomas otológicos y dificultad para dormir en estudiantes con mayor exposición. Conclusión Existe diferencia entre los umbrales auditivos de los estudiantes según la exposición, lo cual podría sugerir alguna asociación con los niveles de ruido a los que se encuentran expuestos.

Objective Evaluating the effect of environmental noise on the auditory health of a group of students from a locality in Bogotá, their educational development and leisure activities and the appearance of neuropsychological symptoms. Methods This was an observational cross-sectional prevalence study in a sample of 581, 10-17 year-old children and adolescents in two district educational institutions, defined as higher (>65 dB) and lower exposure (<65 dB) according to an environmental noise map of the locality, such ranking being subsequently verified. A survey was made regarding their health-related background, perception of being exposed to noise and auditory health-related habits; a liminal tone audiometry of the airway was taken using the criteria recommended in the Infrastructure Technical Advisory Group'snoise-induced hearing loss (ITAG-NIHL) guidelines. Results The more exposed school exceeded the regulations concerning comfortable environmental noise levels (7/8 measurements). Both institutions' levels exceeded WHO recommendations (15/16 measurements); 14.8 % of students had some degree of hearing loss. No significant differences were identified regarding exposure; however, higher thresholds were found in the more exposed group when comparing mean hearing threshold. Students attending morning sessions had a greater prevalence of hearing loss and neuropsychological symptoms and neuro-otological symptoms and difficulty in sleeping was reported amongst the more exposed students. Conclusion A difference was found between students' hearing thresholds, depending on their exposure, suggesting an association with the levels of noise to which they are exposed.
