RESUMO
BACKGROUND: Nonspecific acute tropical febrile illnesses (NEATFI) are common in the Latin American tropics. Dengue, Chikungunya, Zika, Mayaro, and Usutu, among others, can coexist in the American tropics. This study aimed to surveil the arboviruses that cause| acute febrile syndrome in patients in the Meta department, Colombia. METHODS: Between June 2021 and February 2023, an epidemiological surveillance study was conducted in the Llanos of the Meta department in Eastern Colombia. RESULTS: One hundred patients in the acute phase with typical prodromal symptoms of NEATFI infection who attended the emergency department of the Villavicencio Departmental Hospital were included. ELISA tests were performed for Dengue, Usutu, Chikungunya, and Mayaro. RT-qPCR was performed to detect the arboviruses Usutu, Dengue, Zika, Mayaro, and Oropouche. The seroprevalence for the Chikungunya, Mayaro, and Usutu viruses was 41 % (28/68), 40 % (27/67), and 62 % (47/75), respectively. Seroconversion for Chikungunya was observed in one patient; two seroconverted to Mayaro and one to Usutu. The NS5 gene fragment of the Usutu virus was detected in nine febrile patients. RT-qPCR of the remaining arboviruses was negative. The clinical symptoms of the nine Usutu-positive patients were very similar to those of Dengue, Chikungunya, Zika, and Mayaro infections. CONCLUSIONS: The pervasive detection of unexpected viruses such as Usutu and Mayaro demonstrated the importance of searching for other viruses different from Dengue. Because Usutu infection and Mayaro fever have clinical features like Dengue, a new algorithm should be proposed to improve the accuracy of acute tropical fevers.

AIM: To determine the comparative effectiveness of fluid schemes for children with diabetic ketoacidosis (DKA). METHODS: We conducted a systematic review with an attempt to conduct network meta-analysis (NMA). We searched MEDLINE, EMBASE, CENTRAL, Epistemonikos, Virtual Health Library, and gray literature from inception to July 31, 2022. We included randomized controlled trials (RCTs) in children with DKA evaluating any intravenous fluid schemes. We planned to conduct NMA to compare all fluid schemes if heterogeneity was deemed acceptable. RESULTS: Twelve RCTs were included. Studies were heterogeneous in the population (patients and DKA episodes), interventions with different fluids (saline, Ringer's lactate (RL), and polyelectrolyte solution-PlasmaLyte®), tonicity, volume, and administration systems. We identified 47 outcomes that measured clinical manifestations and metabolic control, including single and composite outcomes and substantial heterogeneity preventing statistical combination. No evidence was found of differences in neurological deterioration (main outcome), but differences were found among interventions in some comparisons to normalize acid-base status (â¼2 h less with low vs. high volume); time to receive subcutaneous insulin (â¼1 h less with low vs. high fluid rate); length of stay (â¼6 h less with RL vs. saline); and resolution of the DKA (â¼3 h less with two-bag vs. one-bag scheme). However, available evidence is scarce and poor. CONCLUSIONS: There is not enough evidence to determine the best fluid therapy in terms of fluid type, tonicity, volume, or administration time for DKA treatment. There is an urgent need for more RCTs, and the development of a core outcome set on DKA in children.

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.

RESUMO
Abstract Dengue fever (DF) is the most frequent arboviral disease globally. Deforestation, armed conflicts, and climate change have caused an unprecedented global spread of DF, raising concerns in healthcare systems worldwide. Systemic manifestations of the disease range from mild to severe and, in some cases, can lead to death. Although neurological complications have been reported over the last few decades, they are often neglected or underreported. The present narrative review aims to describe the most important central and peripheral nervous system complications and provide guidance to neurologists in terms of diagnosis and management.
Resumo A dengue é a arbovirose mais frequente no mundo. O desmatamento, os conflitos armados e as mudanças climáticas levaram a uma disseminação global e sem precedentes da dengue, o que gera preocupações na maioria dos sistemas de saúde em todo o mundo. As manifestações sistêmicas variam de leves a graves, incluindo morte. Complicações neurológicas têm sido descritas nas últimas décadas, mas geralmente são negligenciadas ou subnotificadas. O objetivo desta revisão narrativa é descrever as complicações neurológicas centrais e periféricas e auxiliar os neurologistas em seu diagnóstico e manejo.
RESUMO
Abstract Dengue, zika, and chikungunya are arboviruses of great epidemiological relevance worldwide. The emergence and re-emergence of viral infections transmitted by mosquitoes constitute a serious human public health problem. The neurological manifestations caused by these viruses have a high potential for death or sequelae. The complications that occur in the nervous system associated with arboviruses can be a challenge for diagnosis and treatment. In endemic areas, suspected cases should include acute encephalitis, myelitis, encephalomyelitis, polyradiculoneuritis, and/or other syndromes of the central or peripheral nervous system, in the absence of a known explanation. The confirmation diagnosis is based on viral (isolation or RT-PCR) or antigens detection in tissues, blood, cerebrospinal fluid, or other body fluids, increase in IgG antibody titers between paired serum samples, specific IgM antibody in cerebrospinal fluid and serological conversion to IgM between paired serum samples (non-reactive in the acute phase and reactive in the convalescent). The cerebrospinal fluid examination can demonstrate: 1. etiological agent; 2. inflammatory reaction or protein-cytological dissociation depending on the neurological condition; 3. specific IgM, 4. intrathecal synthesis of specific IgG (dengue and chikungunya); 5. exclusion of other infectious agents. The treatment of neurological complications aims to improve the symptoms, while the vaccine represents the great hope for the control and prevention of neuroinvasive arboviruses. This narrative review summarizes the updated epidemiology, general features, neuropathogenesis, and neurological manifestations associated with dengue, zika, and chikungunya infection.
Resumo Dengue, zika e chikungunya são arboviroses de grande relevância epidemiológica em todo o mundo. A emergência e reemergência dessas infecções virais transmitidas por mosquitos constituem um grave problema de saúde pública humana. As manifestações neurológicas causadas por esses vírus têm alto potencial de morte ou sequelas. As complicações que ocorrem no sistema nervoso associadas às arboviroses podem representar um desafio diagnóstico e de tratamento. Em áreas endêmicas, casos suspeitos devem incluir encefalite, mielite, encefalomielite, polirradiculoneurite e/ou outras síndromes do sistema nervoso central ou periférico, na ausência de explicação conhecida. Caso confirmado de arbovirose neuroinvasivo é baseado na detecção viral (isolamento ou RT-PCR) ou de antígenos em tecidos, sangue, líquido cefalorraquidiano ou outros fluidos corporais, aumento dos títulos de anticorpos IgG entre amostras de soro pareadas, anticorpo IgM específico no líquido cefalorraquidiano e conversão sorológica para IgM entre amostras de soro pareadas. O exame do líquido cefalorraquidiano pode demonstrar: 1. agente etiológico; 2. reação inflamatória ou dissociação proteico-citológica, dependendo do quadro neurológico; 3. valor absoluto de IgM específica; 4. síntese intratecal de anticorpos IgG específicos (dengue e chikungunya); 5. exclusão de outros agentes infecciosos. O tratamento das complicações neurológicas visa melhorar os sintomas, enquanto a vacina representa a grande esperança para o controle e a prevenção das arboviroses neuroinvasivas. Esta revisão narrativa resume a atualização da epidemiologia, características gerais, neuropatogênese e manifestações neurológicas associadas à infecção pelos vírus da dengue, zika e chikungunya.
RESUMO
Introducción: La disfagia resulta de varios mecanismos fisiopatológicos donde sus síntomas no son estáticos ni homogéneos en las personas, especialmente cuando existe disfagia orofaríngea neurogénica. Objetivo: Conocer la percepción y comportamiento en el tiempo de síntomas de disfagia mediante el instrumento Eating Assessment Tool-10 (EAT-10) en pacientes con disfagia orofaríngea neurogénica, con el fin de visualizar la dinámica clínica de esta forma de disfagia. Metodología: Estudio observacional tipo cohorte en pacientes con disfagia orofaríngea neurogénica de causas neurológicas y neuromusculares, con seguimiento a tres y seis meses y diligenciamiento del EAT-10 al momento basal, tercer y sexto mes. Resultados: Un total de 90 personas con evaluación basal, de las cuales el 56,7 % (51/90) lograron seguimiento al tercer mes y 25,6 % (23/90) al sexto mes. Los síntomas de disfagia con mayor autopercepción en los tres momentos fueron la dificultad para tragar sólidos, sensación de comida pegada en garganta y tos al comer. La odinofagia no fue un síntoma habitualmente percibido. La puntuación total del EAT-10 estuvo entre 16,61 ± 9 y 18,1 ± 9,5 puntos en general. En pacientes con seguimiento completo se observó variación en la autopercepción para tragar líquidos y pastillas. Se observó variación del puntaje al ajustarlo por recepción de terapias. Discusión: Las enfermedades neurológicas y neuromusculares impactan directamente la deglución con gravedad entre leve a profunda, donde la autopercepción de síntomas deglutorios es dinámica, pero con síntomas cardinales de disfagia orofaríngea en el tiempo. Conclusiones: El reconocimiento y seguimiento de síntomas de disfagia deben ser aspectos usuales en la atención de pacientes con enfermedades neurológicas y neuromusculares.
Introduction: Dysphagia results from several pathophysiological mechanisms where its symptoms are not static or homogeneous in people, especially when there is neurogenic oropharyngeal dysphagia. Objective: To know the perception and behavior over time of symptoms of dysphagia using the Eating Assessment Tool-10 (EAT-10) in patients with neurogenic oropharyngeal dysphagia to visualize the clinical dynamics of this form of dysphagia. Methodology: Observational cohort study in patients with neurogenic oropharyngeal dysphagia of neurological and neuromuscular causes with, follow-up at three and six months, and completion of the EAT-10 at baseline, third and sixth month. Results: A total of 90 people with baseline evaluation were included, of whom 56.7% (51/90) achieved follow-up at the third month and 25.6% (23/90) at the sixth month. Symptoms of dysphagia with greater self-perception at all three moments were difficulty swallowing solids, sensation of food stuck in the throat and coughing when eating. Odynophagia was not a commonly perceived symptom. The total score of the EAT-10 was between 16.61±9 and 18.1±9.5 points in general. In patients with complete follow-up, variation in self-perception of swallowing liquids and pills was observed. Variation of the score when adjusting for the reception of therapies. Discussion: Neurological and neuromuscular diseases directly impact swallowing with mild to profound severity, where self-perception of swallowing symptoms is dynamic, but with cardinal symptoms of oropharyngeal dysphagia over time. Conclusions: The recognition and monitoring of dysphagia symptoms should be usual aspects in the care of patients with neurological and neuromuscular diseases.
RESUMO
El síndrome de compresión medular es una urgencia neuroquirúrgica debido a que un diagnóstico precoz y un tratamiento temprano podría revertir las incapacitantes secuelas ocasionadas por esta enfermedad. Las causas de este síndrome pueden ser traumática, metastásica, infecciosa y vascular (hematomas). La etiología infecciosa no es frecuente y el principal germen involucrado suele ser Staphylococcus aureus. A continuación presentamos el caso de una paciente de 58 años con síndrome de compresión medular de etiología infecciosa quien fue ingresada en el Servicio de Clínica Médica del Centro Médico Nacional.
Spinal cord compression syndrome is a neurosurgical emergency because early diagnosis and early treatment could reverse the disabling consequences caused by this disease. The causes of this syndrome can be traumatic, metastatic, infectious, and vascular (hematomas). Infectious etiology is not frequent and the main germ involved is usually Staphylococcus aureus. Below we present the case of a 58-year-old patient with spinal cord compression syndrome of infectious etiology who was admitted to the Medical Clinic Service of the National Medical Center.
RESUMO
Resumen Objetivo: Determinar la latencia diagnóstica en la enfermedad de Parkinson (EP), así como su relación con variables clínicas y demográficas. Determinar la percepción de síntomas no motores: disfunción olfatoria, trastorno conductual del sueño MOR, depresión y estreñimiento, previos al diagnóstico de EP. Materiales y métodos: Estudio transversal realizado en Yucatán, México en sujetos con EP. Se analizó la asociación entre la latencia diagnóstica con variables clínicas y demográficas usando las pruebas estadísticas no paramétricas: U de Mann Whitney y Kruskal-Wallis. Resultados: Se incluyeron un total de 60 sujetos con una edad promedio de 66.7 años. El tiempo promedio transcurrido desde el inicio del primer síntoma motor hasta el diagnóstico fue de 20.8 meses. El tener antecedentes familiares de EP se asoció significativamente (p=0.031) con una latencia diagnóstica más prolongada en comparación con aquellos pacientes que no refirieron familiares con EP. En cualquier momento antes del diagnóstico de EP: el 36.6% de los pacientes percibieron estreñimiento, 15% depresión, 13.3% trastorno conductual del sueño MOR y 11.6% disfunción olfatoria, 51.7% no refirió ninguno. Conclusiones: La latencia diagnóstica promedio de un grupo de 60 pacientes con EP diagnosticados en Yucatán fue de 20.8 meses. La latencia diagnóstica no se asoció significativamente con el tipo de servicio médico de neurología que realizó en diagnóstico de EP (público o privado), ni con otras variables clínicas ni demográficas además del antecedente familiar de EP.
Abstract Objective: To determine the diagnostic latency in Parkinson's disease (PD), and its relationship with clinical and demographic variables. To determine the perception of non-motor symptoms: olfactory dysfunction, REM sleep behavior disorder, depression, and constipation, prior to the diagnosis of PD. Materials and methods: Cross-sectional study conducted in Yucatan, Mexico in subjects with PD. The association between diagnostic latency with clinical and demographic variables was analyzed using the non-parametric statistical tests: Mann Whitney U and Kruskal-Wallis. Results: A total of 60 subjects with a mean age of 66.7 years were included. The average time elapsed from the onset of the first sympoton to diagnosis was 20.8 months. A family history of PD was significantly associated (p=0.031) with a longer diagnostic latency compared to those patients who did not have relatives with PD. Before the diagnosis of PD: 36.6% of the patients perceived constipation, 15% depression, 13.3% REM sleep behavior disorder and 11.6% olfactory dysfunction, 51.7% did not report any. Conclusions: The mean diagnostic latency of a group of 60 patients with PD diagnosed in Yucatan was 20.8 months. Diagnostic latency was not significantly associated with the type of neurological medical service that performed the diagnosis (public or private), or with other clinical or demographic variables in addition to a family history of PD.
RESUMO
COVID-19 is an infection, primarily respiratory, caused by the SARS-CoV-2, which can also affect the central nervous system, causing neuropsychological damage. There are studies describing post-COVID-19 cognitive deficits, but it is important to know this outcome in populations with different social, biological, and cultural characteristics. Objective: The aim of this study was to assess the self-perception of cognitive sequelae in post-COVID-19 individuals and identify whether there is a possible relationship between the outcome of the participants' self-perception and sociodemographic and clinical data. Methods: This is a cross-sectional study, carried out through an online questionnaire on the Google Forms platform, in which sociodemographic data, general health data, clinical manifestations of COVID-19, and post-COVID-19 self-perception of the cognitive domains of memory, attention, language, and executive functions were collected. Results: The final sample consisted of 137 participants, and it was possible to identify that memory and attention were the domains with the highest impression of worsening post-COVID-19, followed by executive functions and language. In addition, it was identified that being female may be related to a worse self-perception of all cognitive functions and that having depression or other psychiatric diseases and obesity can significantly affect at least half of the cognitive domains evaluated. Conclusions: This study pointed to a post-COVID-19 cognitive worsening of the participants.
A COVID-19 é uma infecção, primariamente respiratória, causada pelo vírus SARS-CoV-2, mas que também pode atingir o sistema nervoso central, ocasionando danos neuropsicológicos. Há estudos que descrevem os déficits cognitivos pós-COVID-19, mas é importante conhecer esse desfecho em populações com diferentes características sociais, biológicas e culturais. Objetivo: Avaliar a autopercepção de sequelas cognitivas em indivíduos pós-COVID-19 e identificar se há uma possível relação entre o desfecho da autopercepção dos participantes e dados sociodemográficos e clínicos. Métodos: Trata-se de um estudo transversal, realizado com o uso de um questionário online na plataforma Google Forms, no qual foram identificados dados sociodemográficos, dados de saúde geral, manifestações clínicas da COVID-19 e a autopercepção dos domínios cognitivos de memória, atenção, linguagem e funções executivas pós-COVID-19. Resultados: A amostra final foi composta de 137 participantes, e pôde-se observar que memória e atenção foram os domínios com maior impressão de piora pós-COVID-19, seguidos por funções executivas e linguagem. Além disso, constatou-se que ser do gênero feminino pode estar relacionado com uma pior autopercepção de todas as funções cognitivas pós-COVID-19 e que ter depressão ou outras doenças psiquiátricas e obesidade pode afetar significativamente pelo menos metade dos domínios cognitivos avaliados. Conclusões: Este trabalho apontou para a piora cognitiva pós-COVID-19 dos participantes.
RESUMO
Introducción: la disfagia es un trastorno de la deglución, el cual es habitualmente desatendido por profesionales de la salud, en especial la disfagia orofaríngea neurogénica, que es capaz de producir varios síntomas, signos y complicaciones secundarias en los pacientes. Objetivo: realizar una caracterización clínica incluyendo percepción de síntomas de disfagia en pacientes con disfagia orofaríngea neurogénica de causas neurológicas y neuromusculares en Antioquia, Colombia entre los años 2019 y 2021. Metodología: estudio transversal realizado en 80 pacientes con disfagia orofaríngea neurogénica confirmada a través de la herramienta Eating Assessment Tool-10, evaluación clínica y/o resultados de video fluoroscopia de la deglución. Resultados: 71 pacientes presentaron causas neurológicas centrales. La enfermedad cerebrovascular y la enfermedad de Parkinson fueron las etiologías más frecuentes. Solo 18% de los pacientes con causas neurológicas y 33% con causas neuromusculares reportaron tolerancia a todas las consistencias de alimentos. Mediana de 16 puntos en cuanto a autopercepción de síntomas de disfagia mediante el instrumento Eating Assessment Tool-10, con puntuaciones más altas en pacientes con presencia de gastrostomía, antecedente de neumonía, odinofagia y alteración en la oclusión mandibular al examen físico. En los pacientes con causas neurológicas hubo mayor presencia de signos motores linguales y apraxias orofaciales. Conclusión: existen características clínicas como sensación de comida pegada, dificultad para tragar alimentos sólidos, tos y ahogo al tragar, que son útiles en el reconocimiento de casos de disfagia orofaríngea, y apoyan que esta genera más síntomas que signos al examen físico en pacientes con condiciones neurológicas y neuromusculares.
Introduction: dysphagia is a swallowing disorder that is usually neglected by health professionals, especially neurogenic oropharyngeal dysphagia, which can produce various symptoms, signs and secondary complications in patients. Objective: to perform a clinical characterization, including perception of dysphagia symptoms, in patients with neurogenic oropharyngeal dysphagia of neurological and neuromuscular causes in Antioquia, Colombia between 2019 and 2021. Methodology: cross-sectional study conducted in 80 patients with neurogenic oropharyngeal dysphagia confirmed through the Eating Assessment Tool-10, clinical assessment and/ or video fluoroscopy results of swallowing. Results: 71 patients presented central neurological causes. Cerebrovascular disease and Parkinson's disease were the most frequent etiologies. Only 18% of patients with neurological causes and 33% with neuromuscular causes reported tolerance to all food consistencies. Median of 16 points in terms of self-perception of dysphagia symptoms using the Eating Assessment Tool-10, with higher scores in patients with gastrostomy, a history of pneumonia, odynophagia, and abnormal mandibular occlusion on physical examination. In patients with neurological causes, there was a greater presence of lingual motor signs and orofacial apraxia. Conclusion: there are clinical characteristics such as a sensation of stuck food, difficulty swallowing solid foods, coughing, and choking when swallowing, which are useful in recognizing cases of oropharyngeal dysphagia, and support that this generates more symptoms than signs on physical examination in patients with neurological and neuromuscular conditions.

Abstract Introduction Parapharyngeal space tumors with complex anatomy and diverse histology have remained a challenging phenomenon for treating physicians. Objectives We have conducted a comprehensive web search on the PubMed, Web of Science, EMBASE, Cochrane Library, Biomedical Literature Database (CBM), and Clinicaltrials.gov databases to determine the factors that are associated with postoperative complications in parapharyngeal space tumors. Data Synthesis Two researchers reviewed all identified articles independently with a third reviewer for adjudication. Patient demographics and other clinicopathological characteristics were explored. The systematic review has identified 631 benign parapharyngeal space tumors with neurogenic and salivary tissue histology in 13 studies, with a mean age of 42.9 ± 7.76 years old and a median follow-up of 40.98 ± 19.1 months. Salivary gland (50.8%) and neurogenic (49.1%) tumors were the most common histological entities. Tumor size, location, histology, deep parotid lobe involvement, and proximity to great vessels or to the skull base were the deciding factors in selecting the surgical approach. The factors considered to select the surgical approach do not seem to have a correlation with the outcome in terms of neurological sequalae (p = 0.106). Tumors with neurogenic histology have significantly increased chances of developing neurological complication (OR 6.07; p = 0.001). Conclusion Neurologic complications are significantly associated with neurogenic benign tumors rather than surgical approach.
RESUMO
Subdural effusions (SE) have already been associated with several viruses, but there are few associations with Covid-19 reported to date, and all of them had one thing in common: the presence of superimposed bacterial rhinosinusitis. Here we describe the case of a 76-year-old male patient that was transferred to our center due to severe SARS-CoV-2 infection and developed a SE during hospital stay. He presented sensory level impairment during hospitalization, but an initial Head CT scan showed no alterations. A new CT scan performed six days later evidentiated a bilateral SE. The patient had a cardiorespiratory arrest during the night of the same day, resulting in death. Covid-19 as a direct cause of subdural effusion (positive Covid-19 PCR in subdural fluid) has never before been reported in the literature, and, unfortunately, it was not possible to rule out or confirm this phenomenon in our case due to the rapid evolution of the clinical picture. However, our case clearly differs from the literature as the patient did not show any signs of sinus disease or intracranial hypotension, and the possible causes of the effusion boil down to spontaneity and the direct action of Covid-19 in the CNS and subdural space.
RESUMO
Fundamento la COVID-19 es causada por el virus del SARS-Cov-2 y presenta una amplia sintomatología, tanto en su fase aguda como en su fase crónica. Entre los sistemas que afecta se encuentra el Nervioso, debido a su mecanismo neurotrópico. Objetivo determinar el riesgo de complicaciones neurológicas asociadas a la severidad de la COVID-19 en pacientes adultos. Métodos se realizó un estudio descriptivo y transversal, que incluyó a 143 pacientes positivos a COVID-19 atendidos en el Hospital San Vicente de Paúl, de Ibarra, Ecuador, durante el año de 2021. Se analizaron las complicaciones neurológicas y la severidad de la COVID-19. Como medida de asociación para dichas variables, se utilizó Test de Fisher (p = ≤ 0,05) y se realizó un análisis bivariado. Resultados el 54 % de los pacientes presentó complicaciones neurológicas del Sistema Nervioso Central, mientras que el 46 % fue del Sistema Nervioso Periférico; y fue la severidad leve-moderada la de mayor frecuencia (41 %), y la alteración auditiva la que mayor probabilidad estadística tuvo de presentarse (OR= 74,968; IC: 95 %). La tasa de letalidad en estos pacientes fue de 7,1 %; y en aquellos con complicaciones neurológicas, de 8,4 %. Conclusión las secuelas neurológicas con mayor probabilidad de presentarse fueron la alteración auditiva y la alteración del gusto, en pacientes con severidad leve y severidad grave, respectivamente; además de polineuropatía en pacientes con severidad crítica, la cual también se presentó en pacientes fallecidos.
Background COVID-19 is caused by the SARS-Cov-2 virus and presents a wide range of symptoms, both in its acute phase and in its chronic phase. Among the systems that it affects is the Nervous, due to its neurotropic mechanism. Objective to determine the risk of neurological complications associated with the COVID-19 severity in adult patients. Methods a descriptive and cross-sectional study was carried out, which included 143 positive patients for COVID-19 treated at the San Vicente de Paúl Hospital, in Ibarra, Ecuador, during 2021. Neurological complications and the severity of the COVID-19 disease were analyzed. As a measure of association for these variables, the Fisher Test was used (p = ≤ 0.05) and a bivariate analysis was performed. Results 54% of the patients presented neurological complications of the Central Nervous System, while 46% were of the Peripheral Nervous System; and mild-moderate severity was the most frequent (41%), and hearing impairment had the highest statistical probability of occurring (OR= 74.968; CI: 95%). The case fatality rate in these patients was 7.1%; and in those with neurological complications, 8.4%. Conclusion the neurological sequelae most likely to occur were hearing impairment and taste impairment, in patients with mild severity and serious severity, respectively; in addition to polyneuropathy in patients with critical severity, which also occurred in deceased patients.
RESUMO
Objective: The present study seeks to overcome the lack of data on Covid-19 associated intracranial hemorrhage (ICH) in Brazil. Methods: This is a retrospective, single-center case series of consecutive patients. It is a subanalysis of a larger study still in progress, which covers all neurological manifestations that occurred in patients admitted between March 1st, 2020 and June 1st, 2022, with active SARS-CoV-2 infection confirmed by polymerase chain reaction test. All patients with non-traumatic ICH were included. Results: A total of 1675 patients were evaluated: 917 (54.75 %) had one or more neurological symptoms and 19 had non-traumatic ICH, comprising an incidence of 1.13 %. All patients had one or more risk factors for ICH. The presence of neurological manifestations before the ICH and ICU admission showed a statistically significant relationship with the occurrence of ICH (X2 = 6.734, p = 0.0095; OR = 4.47; CI = 1.3-15.4; and FET = 9.13; p = <0.001; OR = 9.15; CI = 3.27-25.5 respectively). Conclusion: Our findings were largely congruent with the world literature. We believe that the assessment of risk factors can accurately predict the subgroup of patients at increased risk of ICH, but further studies are needed to confirm these hypotheses.
RESUMO
Introduction Parapharyngeal space tumors with complex anatomy and diverse histology have remained a challenging phenomenon for treating physicians. Objectives We have conducted a comprehensive web search on the PubMed, Web of Science, EMBASE, Cochrane Library, Biomedical Literature Database (CBM), and Clinicaltrials.gov databases to determine the factors that are associated with postoperative complications in parapharyngeal space tumors. Data Synthesis Two researchers reviewed all identified articles independently with a third reviewer for adjudication. Patient demographics and other clinicopathological characteristics were explored. The systematic review has identified 631 benign parapharyngeal space tumors with neurogenic and salivary tissue histology in 13 studies, with a mean age of 42.9 ± 7.76 years old and a median follow-up of 40.98 ± 19.1 months. Salivary gland (50.8%) and neurogenic (49.1%) tumors were the most common histological entities. Tumor size, location, histology, deep parotid lobe involvement, and proximity to great vessels or to the skull base were the deciding factors in selecting the surgical approach. The factors considered to select the surgical approach do not seem to have a correlation with the outcome in terms of neurological sequalae ( p = 0.106). Tumors with neurogenic histology have significantly increased chances of developing neurological complication (OR 6.07; p = 0.001). Conclusion Neurologic complications are significantly associated with neurogenic benign tumors rather than surgical approach.
RESUMO
ABSTRACT Chikungunya fever (CHIK) is a neglected tropical disease associated with chronic arthritis. CHIK is usually a self-limiting condition; however, extra-articular manifestations present as atypical illness in a minority of patients. These atypical features may mimic other conditions and potentially distract physicians from the true diagnosis. This review analyzes the evidence of many unusual extra-articular manifestations reported in cases of CHIK. Depending on the affected system, these unusual manifestations include encephalitis, myocarditis, acute interstitial nephritis, cutaneous manifestations, acute anterior uveitis, abdominal pain, and depression. In addition, coinfections and comorbidities may cause atypical illness and obscure the diagnosis. Further studies are required to clarify the pathophysiology and natural history of CHIK, as it remains a burdening condition. Exploring its atypical symptoms may be the missing scientific piece of this puzzle.
RESUMO
ABSTRACT Objective To evaluate whether intrathecal chemotherapy improves clinical outcomes in patients with meningeal carcinomatosis. Methods This retrospective cohort study included consecutive patients with breast cancer diagnosed with meningeal carcinomatosis. Clinical and treatment data were collected from the patients' medical charts. The primary outcome was overall survival, and the secondary outcomes were time to neurological deterioration and reporting of clinical benefit. Logistic regression and Cox proportional hazard models adjusted for potential confounders were used to evaluate the clinical response and overall survival, respectively. Results Overall, 109 female patients were included, 50 (45.9%) of whom received intrathecal chemotherapy with methotrexate and dexamethasone. The median treatment duration was 3 weeks (range, 1-13 weeks). Patients treated with intrathecal chemotherapy were more likely to report clinical benefit (74% versus 57.7%, adjusted odds ratio [OR] = 9.0, 95%CI=2.6-30.9, p<0.001). However, there was no difference in the time to neurologic deterioration (hazard ratio [HR] = 0.96, 95%CI= 0.57-1.59, p=0.86). Patients who received intrathecal chemotherapy did not show an increase in overall survival compared with that of patients who did not receive intrathecal chemotherapy (median overall survival = 1.8 months, 95%CI= 1.27-3.0 versus 2.5, 95%CI= 1.9-3.9, adjusted HR = 0.71, 95%CI= 0.41-1.22, p=0.21). There was a significant interaction between intrathecal chemotherapy and systemic treatment, and patients who received systemic therapy without intrathecal chemotherapy had better overall survival than that of the no-treatment group (adjusted HR = 0.38, 95%CI= 0.20-0.70, p=0.002). Conclusion Intrathecal chemotherapy did not increase overall survival or time to neurological deterioration and should not preclude or postpone systemic treatments.
RESUMO
Abstract Background The neurological manifestations in COVID-19 adversely impact acute illness and post-disease quality of life. Limited data exist regarding the association of neurological symptoms and comorbid individuals. Objective To assess neurological symptoms in hospitalized patients with acute COVID-19 and multicomorbidities. Methods Between June 2020 and July 2020, inpatients aged 18 or older, with laboratory-confirmed COVID-19, admitted to the Hospital São Paulo (Federal University of São Paulo), a tertiary referral center for high complexity cases, were questioned about neurological symptoms. The Composite Autonomic Symptom Score 31 (COMPASS-31) questionnaire was used. The data were analyzed as a whole and whether subjective olfactory dysfunction was present or not. Results The mean age of the sample was 55 ± 15.12 years, and 58 patients were male. The neurological symptoms were mostly xerostomia (71%), ageusia/hypogeusia (50%), orthostatic intolerance (49%), anosmia/hyposmia (44%), myalgia (31%), dizziness (24%), xerophthalmia (20%), impaired consciousness (18%), and headache (16%). Furthermore, 91% of the patients had a premorbidity. The 44 patients with subjective olfactory dysfunction were more likely to have hypertension, diabetes, weakness, shortness of breath, ageusia/hypogeusia, dizziness, orthostatic intolerance, and xerophthalmia. The COMPASS-31 score was higher than that of previously published controls (14.85 ± 12.06 vs. 8.9 ± 8.7). The frequency of orthostatic intolerance was 49% in sample and 63.6% in those with subjective olfactory dysfunction (2.9-fold higher risk compared to those without). Conclusion A total of 80% of inpatients with multimorbidity and acute COVID-19 had neurological symptoms. Chemical sense and autonomic symptoms stood out. Orthostatic intolerance occurred in around two-thirds of the patients with anosmia/hyposmia. Hypertension and diabetes were common, mainly in those with anosmia/hyposmia.
Resumo Antecedentes As manifestações neurológicas na COVID-19 impactam adversamente na enfermidade aguda e na qualidade de vida após a doença. Dados limitados existem em relação a associação de sintomas neurológicos e indivíduos com comorbidades. Objetivo Avaliar os sintomas neurológicos em pacientes de hospitalizados com COVID-19 aguda e múltiplas comorbidades. Métodos Entre junho e julho de 2020, pacientes de hospitais com idade 18 anos ou acima e COVID-19 laboratorialmente confirmada, admitidos no Hospital São Paulo (Universidade Federal de São Paulo), um centro de referência terciário para casos de alta complexidade, foram perguntados sobre sintomas neurológicos. O questionário Pontuação composta de sintoma autonômico (COMPASS-31) foi usado. Os dados foram analisados no geral e se a disfunção olfatória subjetiva estava presente ou não. Resultados A média de idade da amostra foi 55 ± 15.12 anos. 58 pacientes eram homens. Os sintomas neurológicos foram principalmente xerostomia (71%), ageusia/hipogeusia (50%), intolerância ortostática (49%), anosmia/hiposmia (44%), mialgia (31%), tontura (24%), xeroftalmia (20%), comprometimento na consciência (18%) e cefaleia (16%). Além disso, 91 % dos pacientes tinham uma pré-morbidade. Os 44 pacientes com disfunção olfatória tinham maior chance de ter hipertensão, diabetes, fraqueza, falta de ar, ageusia/hipogeusia, tontura, intolerância ortostática e xeroftalmia. A pontuação do COMPASS-31 foi maior do que a de controles previamente publicados (14,85 ± 12,06 vs. 8,9 ± 8,7). A frequência de intolerância ortostática foi 49% na amostra e 63,6% naqueles com disfunção olfatória subjetiva (risco 2.9 vezes maior comparado com os sem). Conclusão Um total de 80% dos pacientes hospitalizados com múltiplas morbidades e COVID-19 aguda tinham sintomas neurológicos. Os sintomas do sentido químico e autonômicos se destacaram. A intolerância ortostática ocorreu em cerca de dois terços dos pacientes com anosmia/hiposmia. A hipertensão e o diabetes foram comuns, principalmente naqueles com anosmia/hiposmia.
RESUMO
ABSTRACT. COVID-19 is an infection, primarily respiratory, caused by the SARS-CoV-2, which can also affect the central nervous system, causing neuropsychological damage. There are studies describing post-COVID-19 cognitive deficits, but it is important to know this outcome in populations with different social, biological, and cultural characteristics. Objective: The aim of this study was to assess the self-perception of cognitive sequelae in post-COVID-19 individuals and identify whether there is a possible relationship between the outcome of the participants' self-perception and sociodemographic and clinical data. Methods: This is a cross-sectional study, carried out through an online questionnaire on the Google Forms platform, in which sociodemographic data, general health data, clinical manifestations of COVID-19, and post-COVID-19 self-perception of the cognitive domains of memory, attention, language, and executive functions were collected. Results: The final sample consisted of 137 participants, and it was possible to identify that memory and attention were the domains with the highest impression of worsening post-COVID-19, followed by executive functions and language. In addition, it was identified that being female may be related to a worse self-perception of all cognitive functions and that having depression or other psychiatric diseases and obesity can significantly affect at least half of the cognitive domains evaluated. Conclusions: This study pointed to a post-COVID-19 cognitive worsening of the participants.
RESUMO. A COVID-19 é uma infecção, primariamente respiratória, causada pelo vírus SARS-CoV-2, mas que também pode atingir o sistema nervoso central, ocasionando danos neuropsicológicos. Há estudos que descrevem os déficits cognitivos pós-COVID-19, mas é importante conhecer esse desfecho em populações com diferentes características sociais, biológicas e culturais. Objetivo: Avaliar a autopercepção de sequelas cognitivas em indivíduos pós-COVID-19 e identificar se há uma possível relação entre o desfecho da autopercepção dos participantes e dados sociodemográficos e clínicos. Métodos: Trata-se de um estudo transversal, realizado com o uso de um questionário online na plataforma Google Forms, no qual foram identificados dados sociodemográficos, dados de saúde geral, manifestações clínicas da COVID-19 e a autopercepção dos domínios cognitivos de memória, atenção, linguagem e funções executivas pós-COVID-19. Resultados: A amostra final foi composta de 137 participantes, e pôde-se observar que memória e atenção foram os domínios com maior impressão de piora pós-COVID-19, seguidos por funções executivas e linguagem. Além disso, constatou-se que ser do gênero feminino pode estar relacionado com uma pior autopercepção de todas as funções cognitivas pós-COVID-19 e que ter depressão ou outras doenças psiquiátricas e obesidade pode afetar significativamente pelo menos metade dos domínios cognitivos avaliados. Conclusões: Este trabalho apontou para a piora cognitiva pós-COVID-19 dos participantes.
