Development of a new non invasive prognostic stroke scale (NIPSS) including triage elements for sleep apnea and peripheral artery disease.

BACKGROUND: Although sleep apnea and peripheral artery disease are prognostic factors for stroke, their added benefit in the acute stage to further prognosticate strokes has not been evaluated. OBJECTIVES: We tested the accuracy in the acute stroke stage of a novel score called the Non-Invasive Prognostic Stroke Scale (NIPSS). PATIENTS AND METHODS: Prospective cohort with imaging-confirmed ischemic stroke. Clinical data, sleep apnea risk score (STOPBANG) and blood pressure measures were collected at baseline. Primary outcome was the 90-day modified Rankin Scale (mRS), with poor outcome defined as mRS 3-6. Area under the ROC curve (AUC) was calculated for NIPSS and compared to six other stroke prognostic scores in our cohort: SPAN-100 index, S-SMART, SOAR, ASTRAL, THRIVE, and Dutch Stroke scores. RESULTS: We enrolled 386 participants. After 90 days, there were 56% with poor outcome, more frequently older, female predominant and with higher admission National Institute of Health Stroke Scale (NIHSS). Four variables remained significantly associated with primary endpoint in the multivariable model: age (OR 1.87), NIHSS (OR 7.08), STOPBANG category (OR 1.61), and ankle-braquial index (OR 2.11). NIPSS AUC was 0.86 (0.82-0.89); 0.83 (0.79-0.87) with bootstrapping. When compared to the other scores, NIPSS, ASTRAL, S-SMART and DUTCH scores had good abilities in predicting poor outcome, with AUC of 0.86, 0.86, 0.83 and 0.82, respectively. THRIVE, SOAR and SPAN-100 scores were fairly predictive. DISCUSSION AND CONCLUSIONS: Non-invasive and easily acquired emergency room data can predict clinical outcome after stroke. NIPSS performed equal to or better than other prognostic stroke scales.

Diagnóstico de proteinose alveolar pulmonar após exposição à covid-19: relato de caso / Pulmonary alveolar proteinosis diagnosis of after exposure to covid-19: case report / Diagnóstico de proteinosis alveolar pulmonar tras exposición al covid-19: reporte de caso

Os objetivos deste artigo são relatar o caso de um paciente diagnosticado com proteinose alveolar pulmonar (PAP) após piora do quadro clínico decorrente da infecção por covid-19 e realizar uma revisão sobre a PAP na busca de promover o maior conhecimento dos profissionais de saúde sobre essa comorbidade. Participou da pesquisa um paciente de 48 anos de idade, sexo masculino, com relato de quadro de tosse e dispneia há um ano, apresentando exacerbação do quadro respiratório após infecção por SARS-CoV-2, com necessidade de início de suporte de oxigênio via cateter nasal devido à diminuição da saturação e ao comprometimento das atividades da vida diária. Foi realizada tomografia computadorizada de alta resolução do tórax (TCAR) e evidenciada pavimentação em mosaico com comprometimento difuso dos campos pulmonares. Conforme achados clínicos e radiológicos compatíveis com PAP, o paciente foi submetido à lavagem pulmonar total e apresentou melhora da dispneia e da tosse. A proteinose alveolar pulmonar é uma doença que merece relevância devido ao comprometimento clínico que pode ocasionar ao paciente. É necessário um acompanhamento médico periódico para observar a evolução da doença e definir a conduta terapêutica conforme apresentação clínica de cada enfermo. Por vezes, pode ser necessário repetir a lavagem pulmonar total e em casos refratários, buscar alternativas terapêuticas. Tendo em vista o envolvimento pulmonar e os sintomas semelhantes a infecções por SARS-CoV-2, é importante atentar para os diagnósticos diferenciais.

This paper reports the case of a patient diagnosed with pulmonary alveolar proteinosis (PAP) after a worsening clinical picture due to COVID-19 infection, reviewing the literature on PAP to promote greater knowledge on this comorbidity for health professionals. A 48-year-old male patient with reported coughing and dyspnea for one year, presenting exacerbation of respiratory symptoms after SARS-CoV-2 infection, needing to start oxygen support via nasal catheter due to decreased saturation and impairment of daily living activities. High resolution computed tomography (HRCT) of the chest was performed and showed crazy paving with diffuse involvement of the lung fields. As per clinical and radiological findings compatible with PAP, the patient underwent total lung lavage and showed improvement in dyspnea and coughing. Pulmonary alveolar proteinosis deserves relevance due to the clinical impairment it can cause to the patient. Periodic medical follow-up is necessary to observe the disease evolution and define the therapeutic approach according to the clinical presentation of each patient. Sometimes, it may be necessary to repeat the total lung lavage, and to seek therapeutic alternatives in refractory cases. Given the pulmonary involvement and symptoms similar to SARS-CoV-2 infections, one must pay attention to the differential diagnoses.

Los objetivos de este artículo son presentar el caso de un paciente diagnosticado de proteinosis alveolar pulmonar (PAP) tras empeorar el cuadro clínico debido a infección por covid-19 y realizar una revisión sobre la PAP con el fin de generar más conocimiento a los profesionales sanitarios sobre esta comorbilidad. El caso investigado fue de un paciente masculino de 48 años de edad, con reporte de tos y disnea desde hace un año, que presentaba exacerbación del cuadro respiratorio posterior a infección por SARS-CoV-2, lo que requirió inicio de soporte de oxígeno vía catéter nasal por disminución de la saturación y deterioro de las actividades de la vida diaria. Se realizó una tomografía computarizada de alta resolución (TCAR) de tórax y se observó empedrado en mosaico con afectación difusa de los campos pulmonares. Según los hallazgos clínicos y radiológicos compatibles con PAP, se le realizó al paciente lavado pulmonar total y mejoró la disnea y la tos. La proteinosis alveolar pulmonar es una enfermedad que merece relevancia por el compromiso clínico que puede ocasionar al paciente. Es necesario un seguimiento médico periódico para observar la evolución de la enfermedad y definir el abordaje terapéutico según la presentación clínica de cada paciente. También es necesario repetir el lavado pulmonar total y, en casos refractarios, buscar alternativas terapéuticas. Ante la afectación pulmonar y síntomas similares a infecciones por SARS-CoV-2, es importante prestar atención a los diagnósticos diferenciales.

Guillain-Barré Syndrome and Miller Fisher Syndrome in Association With an Arboviral Outbreak: A Brazilian Case Series.

Introduction: Guillain-Barré syndrome (GBS) in association with arboviruses, such as Zika, chikungunya, and dengue, has been previously documented; however, Miller-Fisher Syndrome (MFS) and other GBS subtypes are rarely reported. Methods: We identified a series of GBS and MFS cases that were followed during the Zika virus outbreak in Salvador, Brazil (2015-2016). Blood and CSF samples were collected for virus diagnosis. In addition, serological studies to verify previous arboviral infection and electromyography (EMG) were performed. Results: Of the 14 patients enrolled, 10 were diagnosed with GBS, including three GBS subtypes (two cases of bifacial weakness with paresthesia and one case of paraparetic GBS), and four as MFS. IgM antibodies against one or more of three arboviruses were present in 11 (78.6%) patients: anti-zika IgM positivity in eight (57%), anti-Chikungunya IgM in three (21%), and anti-Dengue in one (7%) individual. A single case was positive for both anti-Dengue IgM and anti-Chikungunya IgM, suggesting co-infection. EMG revealed an AIDP pattern in all nine patients analyzed. Conclusion: The current case series contributes to our knowledge on the clinical presentation of arbovirus-associated GBS and its subtypes, including MFS, and serves as an alert to clinicians and other healthcare professionals in regions affected by arbovirus outbreaks. We highlight the importance of recognizing arboviruses in diagnosing GBS and its subtypes.

Sangramento gastrointestinal em paciente portador de síndrome de Rendu-Osler-Weber: relato de caso / Gastrointestinal bleeding in a patient with Osler-Weber-Rendu syndrome: a case report / Sangrado gastrointestinal en paciente con síndrome de Rendu-Osler-Weber: reporte de caso

A síndrome de Rendu-Osler-Weber, ou telangiectasia hemorrágica hereditária (THH), é uma doença autossômica dominante de penetrância variável que altera a camada muscular e elástica da parede dos vasos sanguíneos, causando neles grande fragilidade e dilatação e tornando-os suscetíveis a sangramentos secundários, a traumatismos e malformações arteriovenosas (MAV) ­ sendo elas as mais comuns no cérebro, nos pulmões e no trato gastrointestinal e hepático. Este relato de caso tem como objetivo realizar uma revisão sobre essa síndrome, bem como a respeito da melhor terapia e do melhor manejo para sangramentos gastrointestinais por angiectasias. Trata-se de uma paciente de 62 anos de idade, com episódio de hematêmese e melena recorrentes, que foi admitida instável hemodinamicamente e com queda importante dos níveis de hemoglobina, necessitando de múltiplas transfusões sanguíneas. Após entrevista clínica, que chamou a atenção para o histórico familiar de quadros similares, epistaxes recorrentes associados ao exame físico e angiectasias gástricas à endoscopia digestiva alta, foi atribuído o diagnóstico de síndrome de Rendu-Osler-Weber. Angiectasias foram erradicadas com terapia endoscópica usando plasma de argônio. A THH é uma doença subdiagnosticada que merece atenção especial por conta do seu risco de causar hemorragias graves com expressão fenotípica mais aflorada com o avançar da idade. Por seu cunho hereditário, faz-se necessário um acompanhamento médico linear com a família para evitar complicações secundárias da doença, bem como para o manejo adequado de suas apresentações.

Osler-Weber-Rendu syndrome or hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease that changes the muscular and elastic layer of the blood vessel wall, making them fragile and more susceptible to bleeding secondary to trauma and arteriovenous malformations (AVM) ­ a condition that commonly affects the brain, lungs, gastrointestinal tract, and liver. This study aims to perform a literature review on this syndrome, as well as on the best treatment and management for gastrointestinal bleeding from angioctasia. To this end, it reports the case of a 62-year-old female patient with recurrent episodes of hematemesis and melena, who was admitted to hospital with hemodynamic instability and low hemoglobin levels, requiring multiple blood transfusions. After clinical interview, which indicated family history of recurrent epistaxis, physical examination, and upper digestive endoscopy showing gastric angiectasias, the patient was diagnosed with Osler-Weber-Rendu syndrome. Angiectasias were treated with endoscopic argon plasma. Considering the risk of severe hemorrhages and its more pronounced phenotypic expression with advancing age, HHT is an underdiagnosed disease that deserves special attention. Due to its hereditary nature, a linear medical follow-up with the family is necessary to avoid secondary complications of the disease, as well as the proper management of its presentations.

Este estudio tiene como objetivo realizar una revisión de este síndrome, así como la mejor terapia y manejo del sangrado gastrointestinal por angioctasia en esta patología. Se trata de un paciente de 62 años, con episodio de hematemesis recurrente y melena, que ingresa hemodinámicamente inestable y con descenso significativo de los niveles de hemoglobina, requiriendo múltiples transfusiones sanguíneas. Tras entrevista clínica, destacando los antecedentes familiares de patologías similares, epistaxis recurrente, exploración física y angiectasias gástricas a endoscopia digestiva alta, se asignó el diagnóstico de síndrome de Rendu-Osler-Weber. Las angiectasias se erradicaron con terapia endoscópica con plasma de argón. La HHT es una enfermedad infradiagnosticada que merece una atención especial por su riesgo de hemorragias severas, con una expresión fenotípica más pronunciada con el avance de la edad. Además de su carácter hereditario, es necesario un seguimiento médico lineal con la familia para evitar complicaciones secundarias de la enfermedad, así como el adecuado manejo de sus presentaciones.

Opsoclonus-myoclonus-ataxia syndrome associated with chikungunya and dengue virus co-infection.

Opsoclonus-myoclonus-ataxia syndrome (OMAS) is a rare neurological disorder characterized by irregular multidirectional eye movements, myoclonus, cerebellar ataxia, sleep disturbances, and cognitive dysfunction. Although most commonly related to paraneoplastic syndrome, this condition has occasionally been described following infectious illnesses. This article reports the first case of OMAS in association with chikungunya and dengue virus co-infection. The genetic analysis identified chikungunya virus of East/Central/South African genotype and dengue serotype 4 virus of genotype II. This report represents an unusual clinical syndrome associated with viral co-infection and reinforces the need for clinical vigilance with regard to neurological syndromes in the context of emergent arboviruses.

Guillain-Barré Syndrome After Zika Virus Infection in Brazil.

Zika virus (ZIKV) is an emerging flavivirus, which has caused a widespread outbreak in the Americas. Shortly after its introduction in 2015, a cluster of cases with Guillain-Barré syndrome was detected in Brazil. Herein, we describe two cases from the city of Salvador, who developed ascending paresis after an acute exanthematous illness. The patients were admitted to the intensive care unit with tetraparesis and cranial nerve palsy, which resolved after intravenous administration of human immunoglobulin. Serological evaluation detected IgM-specific ZIKV antibodies. In regions of Zika virus transmission, health-care workers must be aware of the potential severe neurological complications associated with ZIKV infection and be prepared to provide prompt diagnosis, treatment, and supportive care.
