Abstract Background Autoimmune encephalitis (AE) consists of a group of acquired diseases that affect the central nervous system. A myriad of phenotypes may be present at the onset. Due to the heterogeneity of clinical presentations, it is difficult to achieve uniformity for the diagnostic and therapeutic processes and follow-up strategies. Objective To describe a series of patients diagnosed with AE in a resource-limited public hospital in southern Brazil and to analyze therapeutics and outcomes. Methods We retrospectively reviewed the electronic medical records of patients diagnosed with AE at the Hospital de Clínicas de Porto Alegre from 2014 to 2022. Data collected included clinical presentation, neuroimaging, cerebrospinal fluid testings, electroencephalogram, autoantibodies, treatments, outcomes, follow-up time, degree of neurological impairment, and mortality. Results Data from 17 patients were retrieved. Eleven cases were classified as definite AE and 6 as possible AE. Autoantibodies were identified in 9 patients. Timing for diagnosis was impacted by the high costs associated with autoantibody testing. Most patients became functionally dependent (82.4%) and most survivors remained with autoimmune-associated epilepsy (75%). Five patients died during hospitalization, and one after a 26-month of follow-up. Conclusion In this resource-limited hospital, patients with AE had a worse clinical outcome than that previously described in the literature. Development of epilepsy during follow-up and mortality were greater, whilst functional outcome was inferior. Autoantibody testing was initially denied in most patients, which impacted the definitive diagnosis and the use of second-line therapies.

Resumo Antecedentes A encefalite autoimune (EA) consiste em um grupo de doenças adquiridas que afetam o sistema nervoso central. Objetivo Descrever uma série de pacientes diagnosticados com EA em um contexto de atenção terciária à saúde com recursos limitados e analisar a terapêutica e os resultados. Métodos Revisamos retrospectivamente os prontuários eletrônicos de pacientes diagnosticados com EA no Hospital de Clínicas de Porto Alegre de 2014 a 2022. Os dados coletados incluíram apresentação clínica, neuroimagem, exames de líquido cefalorraquidiano, eletroencefalograma, autoanticorpos, tratamentos, resultados, tempo de acompanhamento, grau de comprometimento neurológico e mortalidade. Resultados Dados de 17 pacientes foram coletados. Onze casos foram classificados como EA definitivo e seis como EA possível. Autoanticorpos foram identificados em nove pacientes. O tempo para o diagnóstico foi afetado pelos altos custos associados ao teste de autoanticorpos. A maioria dos pacientes tornou-se funcionalmente dependente (82,4%), e a maioria dos sobreviventes permaneceu com epilepsia autoimune associada (75%). Cinco pacientes faleceram durante a internação, e um após 26 meses de seguimento. Conclusão No hospital em questão, os pacientes com EA tiveram um desfecho clínico pior do que o previamente descrito na literatura. O desenvolvimento de epilepsia durante o acompanhamento e a mortalidade foram maiores, enquanto o desfecho funcional foi inferior. Os testes de autoanticorpos foram inicialmente negados para a maioria dos pacientes, o que impactou o diagnóstico definitivo e o uso de terapias de segunda linha.

Abstract Objective To develop the second evidence-based Brazilian Society of Rheumatology consensus for diagnosis and treatment of lupus nephritis (LN). Methods Two methodologists and 20 rheumatologists from Lupus Comittee of Brazilian Society of Rheumatology participate in the development of this guideline. Fourteen PICO questions were defined and a systematic review was performed. Eligible randomized controlled trials were analyzed regarding complete renal remission, partial renal remission, serum creatinine, proteinuria, serum creatinine doubling, progression to end-stage renal disease, renal relapse, and severe adverse events (infections and mortality). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to develop these recommendations. Recommendations required ≥82% of agreement among the voting members and were classified as strongly in favor, weakly in favor, conditional, weakly against or strongly against a particular intervention. Other aspects of LN management (diagnosis, general principles of treatment, treatment of comorbidities and refractory cases) were evaluated through literature review and expert opinion. Results All SLE patients should undergo creatinine and urinalysis tests to assess renal involvement. Kidney biopsy is considered the gold standard for diagnosing LN but, if it is not available or there is a contraindication to the procedure, therapeutic decisions should be based on clinical and laboratory parameters. Fourteen recommendations were developed. Target Renal response (TRR) was defined as improvement or maintenance of renal function (±10% at baseline of treatment) combined with a decrease in 24-h proteinuria or 24-h UPCR of 25% at 3 months, a decrease of 50% at 6 months, and proteinuria < 0.8 g/24 h at 12 months. Hydroxychloroquine should be prescribed to all SLE patients, except in cases of contraindication. Glucocorticoids should be used at the lowest dose and for the minimal necessary period. In class III or IV (±V), mycophenolate (MMF), cyclophosphamide, MMF plus tacrolimus (TAC), MMF plus belimumab or TAC can be used as induction therapy. For maintenance therapy, MMF or azathioprine (AZA) are the first choice and TAC or cyclosporin or leflunomide can be used in patients who cannot use MMF or AZA. Rituximab can be prescribed in cases of refractory disease. In cases of failure in achieving TRR, it is important to assess adherence, immunosuppressant dosage, adjuvant therapy, comorbidities, and consider biopsy/rebiopsy. Conclusion This consensus provides evidence-based data to guide LN diagnosis and treatment, supporting the development of public and supplementary health policies in Brazil. evidencebased evidence LN. .

Abstract Background Data on post-acute COVID-19 in autoimmune rheumatic diseases (ARD) are scarce, focusing on a single disease, with variable definitions of this condition and time of vaccination. The aim of this study was to evaluate the frequency and pattern of post-acute COVID-19 in vaccinated patients with ARD using established diagnosis criteria. Methods Retrospective evaluation of a prospective cohort of 108 ARD patients and 32 non-ARD controls, diagnosed with SARS-CoV-2 infection (RT-PCR/antigen test) after the third dose of the CoronaVac vaccine. Post-acute COVID-19 (≥ 4 weeks and > 12 weeks of SARS-CoV-2 symptoms) were registered according to the established international criteria. Results ARD patients and non-ARD controls, balanced for age and sex, had high and comparable frequencies of ≥ 4 weeks post-acute COVID-19 (58.3% vs. 53.1%, p = 0.6854) and > 12 weeks post-acute COVID-19 (39.8% vs. 46.9%, p = 0.5419). Regarding ≥ 4 weeks post-acute COVID-19, frequencies of ≥ 3 symptoms were similar in ARD and non-ARD controls (54% vs. 41.2%, p = 0.7886), and this was also similar in > 12 weeks post-acute COVID-19 (68.3% vs. 88.2%, p = 0.1322). Further analysis of the risk factors for ≥ 4 weeks post-acute COVID-19 in ARD patients revealed that age, sex, clinical severity of COVID-19, reinfection, and autoimmune diseases were not associated with this condition (p > 0.05). The clinical manifestations of post-acute COVID-19 were similar in both groups (p > 0.05), with fatigue and memory loss being the most frequent manifestations. Conclusion We provide novel data demonstrating that immune/inflammatory ARD disturbances after third dose vaccination do not seem to be a major determinant of post-acute COVID-19 since its pattern is very similar to that of the general population.

Abstract Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results: All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion: These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.

Estudo de revisão integrativa da literatura com o objetivo de buscar evidências que subsidiem a incorporação do ozônio como agente esterilizante de produtos para saúde. A busca foi realizada nas bases MEDLINE, SCOPUS, COCHRANE, COMPENDEX, INSPEC E ENGINEERING RESEARCH DATABASE, utilizando-se os descritores ozone e sterilization. Foram obtidas cinco publicações, entre 1990 e 2008, que testaram o ozônio como esterilizante. Todas utilizaram o mesmo tipo de investigação (experimental laboratorial) e alcançaram esterilização pelo ozônio, porém com variados escopos e produtos testados, além de diversos procedimentos metodológicos. Tendo em vista a incessante tecnologia de novos produtos, com ampla variedade de conformações e matéria-prima, os achados denotam o ozônio um método promissor, porém ainda em fase inicial de investigação. Mais estudos experimentais ainda são necessários, de maneira a subsidiar evidências mais amplas sobre suas possibilidades e limitações.

The objective of this integrative literature review was to find evidence to support using ozone as a sterilizing agent for health products. The search was performed on the following bases: MEDLINE, SCOPUS, COCHRANE, COMPENDEX, INSPEC and ENGINEERING RESEARCH DATABASE; using ozone and sterilization as descriptors. Five articles were found between 1990 and 2008, which tested ozone as a sterilizer. All studies used the same type of investigation (experimental laboratory study) and achieved sterilization with ozone, but with different scopes and products, besides using different methodological procedures. Considering the ever-growing technology for new products, with the vast range of forms and materials, the findings point at ozone sterilization as a promising method, but still in an initial phase of investigation. Further experimental studies are needed to provide broader evidence regarding the possibilities and limitations of ozone sterilization.

Neoplasias do ânus correspondem de 2 a 4% dos tumores de intestino grosso, sendo predominante nas sétima e oitava décadas. A maior prevalência é em gênero feminino, com proporção de 3:1. O aumento da prevalência na população nos últimos anos provavelmente está relacionado ao número maior de pessoas com doenças sexualmente transmissíveis, principalmente o papilomavírus humano (tipos 16 e 18, mais comumente) e/ou o vírus da imunodeficiência humana. O diagnóstico é feito a partir de achados clínicos somados ao exame anatomopatológico. O tratamento de escolha baseia-se na radioquimioterapia, sendo a cirurgia de resgate com amputação abdominoperineal utilizada para casos de recidiva ou persistência. Foi feito um estudo observacional longitudinal retrospectivo e prospectivo, com 11 pacientes diagnosticados com neoplasia anal no período de 2004 a 2010. Seis (54,5%) eram do gênero feminino e 5 (45,5%) do masculino. O pico de incidência foi em sexta década, com média de idade de 54,45 anos. O tipo histológico mais encontrado foi o carcinoma epidermoide (72,7%), sendo o moderadamente diferenciado o mais frequente grau de diferenciação. A quimioterapia associada à radioterapia foi instituída em 81,9% dos pacientes, sendo necessária a cirurgia de amputação abdominoperineal como terapia de resgate em 18,2% dos pacientes.

Anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. Females are mostly affected, and the ratio is 3:1. Its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly) and/or the human immunodeficiency virus. Diagnosis is based on clinical findings and anatomopathological tests. The treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. A retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. Six (54.5%) were females and five (45.5%) were males. The incidence was higher in the sixth decade, at the mean age of 54.45 years. The most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. Chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.

A ligadura elástica (LE) é considerada um método minimamente invasivo para o tratamento da doença hemorroidária (DH) e apresenta vantagens em relação à hemorroidectomia, como: simplicidade de execução e realização ambulatorial sem o emprego de anestesia. Trata-se de um método eficaz, principalmente nos portadores de DH grau II. Porém, apresenta complicações, sendo as mais frequentes: dor, tenesmo, hematoquezia e retenção urinária. Alguns trabalhos mostram complicações mais graves, como sangramentos vultosos que necessitaram de hemotransfusão. Assim, este trabalho avaliou a eficácia e a morbidade do tratamento da DH pelo método da LE. Foi um estudo prospectivo, com 59 pacientes. Destes, cinco (8,5%) eram portadores de DH grau I, 33 (55,9%) de DH grau II e 21 (35,6%) de DH grau III. Todos os pacientes foram submetidos pelo menos a duas sessões. Nas 135 sessões realizadas, encontramos: hematoquezia em 62 (45,9%), dor intensa em 39 (28,9%), sintomas vagais em 10 (7,4%) e pseudoestrangulamento em um (0,7%) sessão. A taxa de cura do prolapso hemorroidário entre os portadores de DH grau II foi de 87,9% e entre aqueles com DH grau III, de 76,2%. O tratamento da DH pelo método da ligadura elástica mostrou-se seguro e com boa taxa de cura.

Rubber band ligation (RB) is considered a minimally invasive method for the treatment of hemorrhoidal disease (HD) and has advantages in relation to hemorrhoidectomy whereby: simplicity of execution, outpatient realization and no need of anesthesia. It is an effective method, especially in the HD grade II. However, shows complications, and the most frequents are: anal pain, tenesmus, hematochezia and urinary retention. Some studies have shown severe complications as major bleeding that needs blood transfusion. Thus, this study evaluated the effectiveness and the morbidity of the treatment of HD by the method of RB. It was a prospective study with 59 patients. Five (8,5%) patients had HD graded in the first degree, 33 (55,9%) in the second degree and 21 (35,6%) in the third. All patients were submitted to at least two sessions. In the 135 sessions performed, we found: hematochezia in 62 (45.9%), severe pain in 39 (28.9%), vagal symptoms in 10 (7.4%) and pseudostrangulation in 1 (0.7%) session. The cure rate of hemorrhoidal prolapse among patients with HD grade II was 87.9% and among those with HD grade III, 76.2%. The treatment of HD by the method of RB proved to be safe and with good cure rate.

Embora muitos estudos tenham demonstrado uma alta prevalência de transtornos psiquiátricos em pacientes com epilepsia, a maioria utilizou entrevistas psiquiátricas não-estruturadas para o diagnóstico. Este método pode levar a diferenças significativas nos resultados. Nós estudamos a prevalência de comorbidades psiquiátricas em pacientes com epilepsia do lobo temporal (ELT), utilizando uma entrevista clínica estruturada. Foram estudados 166 pacientes com ELT, aos quais foi aplicada a Entrevista Clínica Estruturada para o DSM-IV (SCID). Cento e seis pacientes (63,9%) apresentaram comorbidades psiquiátricas. Transtornos de humor, observados em 80 pacientes (48,2%), foram o transtorno neuropsiquiátrico mais comum. Transtornos de ansiedade, observados em 51 pacientes (30,7%), foram a segunda comorbidade psiquiátrica mais frequente. Transtornos psicóticos foram encontrados em 14 (8,4%), e abuso de substâncias foram observados em 8 pacientes (4,8%), respectivamente. Nossos resultados estão de acordo com os dados da literatura, que demonstra problemas psiquiátricos em 10-60% dos pacientes com epilepsia. A grande variação dos resultados pode ser atribuída aos diferentes grupos de pacientes estudados e à variabilidade de métodos diagnósticos empregados. Entrevistas psiquiátricas estruturadas podem contribuir para uma avaliação mais adequada da real prevalência de comorbidades psiquiátricas na ELT.

A great prevalence of psychiatric disorders in epilepsy is well demonstrated, although most studies have used unstructured psychiatric interviews for diagnosis. Here we present a study evaluating the prevalence of psychiatric comorbidities in a cohort of Southern Brazilian patients with temporal lobe epilepsy (TLE) using a structured clinical interview. We analyzed 166 patients with TLE regarding neuropsychiatric symptoms through the Structured Clinical Interview for DSM-IV. One hundred-six patients (63.9%) presented psychiatric comorbidities. Mood disorders were observed in 80 patients (48.2%), anxiety disorders in 51 patients (30.7%), psychotic disorders in 14 (8.4%), and substance abuse in 8 patients (4.8%) respectively. Our results agree with literature data where most authors detected mental disorders in 10 to 60% of epileptic patients. This wide variation is probably attributable to different patient groups investigated and to the great variety of diagnostic methods. Structured psychiatric interviews might contribute to a better evaluation of prevalence of psychiatric comorbidities in TLE.

DESENHO DO ESTUDO: Dois relatos de caso de cisto de fissura coroidal no corno temporal associado com crise parcial complexa. OBJETIVOS: Descrever o curso clínico, achados radiológicos e fazer uma revisão da literatura a respeito de cistos da fissura coroidal. RESUMO DOS DADOS DA LITERATURA: existem poucos casos descritos de cistos da fissura coroidal. RESULTADOS: Nós descrevemos dois pacientes com crises parciais complexas e cistos de fissura coroidal. As crises foram controladas em ambos os pacientes. CONCLUSÃO: O diagnóstico de cisto da fissura coroidal deve ser levado em conta no diagnóstico diferencial de cistos do lobo temporal e em crises de lobo temporal.

STUDY DESIGN: Two case reports of a choroidal fissure cyst in the temporal horn associated with complex partial seizure. OBJECTIVES: To describe the clinical course, image findings and literature review of choroidal fissure cysts. SUMMARY AND BACKGROUND DATA: there are few reported cases of choroidal fissure cysts. RESULTS: We report two patients with complex partial seizures and temporal choroidal fissure cysts. The seizures were controlled in both patients. CONCLUSION: The choroidal fissure cyst diagnosis must highlight the importance of considering this lesion in the differential diagnosis of temporal lobe cyst and temporal lobe seizure.

INTRODUÇÃO: Estima-se que um terço dos casos de pacientes com espectro autista vai apresentar ao menos uma crise epiléptica até a adolescência. Esta associação entre transtornos invasivos do desenvolvimento e epilepsia vem sendo amplamente estudada, mas ainda com inúmeros questionamentos sem resposta na literatura. OBJETIVO: Os autores apresentam o caso de uma criança, com quadro de Transtorno Invasivo do Desenvolvimento - espectro autista - e epilepsia de difícil controle submetida à cirurgia, revisando aspectos fundamentais desta associação. CONCLUSÃO: A partir do caso em questão e de estudos existentes, é pertinente questionar quais são os indícios que nos fazem acreditar que crises epilépticas recorrentes ou uma atividade elétrica anormal sejam responsáveis por alterações cognitivas, de linguagem ou de conduta e qual o tratamento ideal para estas crianças nas quais co-existem os dois diagnósticos.

INTRODUCTION: Some reports have indicated that one third of children with autistic spectrum disorder will present at least one seizure untill early adolescence. The association between autism and epilepsy is recognized but remains unresolved and poorly understood. OBJECTIVE: The authors present a child with autistic spectrum disorder and infantile spasms in the first year of life who underwent resective surgery for intractable epilepsy and discuss aspects of this relationship. CONCLUSION: Despite a growing number of studies involving autism and epilepsy we must point out how is the evidence that recurrent seizures or abnormal electrical activity can cause cognitive, language or behavioral abnormalities and what is the ideal treatment for these children in whom a neurodevelopmental disorder coexists with epilepsy.

INTRODUÇÃO: Pacientes com epilepsia generalizada primária (idiopática) podem, raramente, não responder ao tratamento medicamentoso e assim apresentar crises tônico-clônicas generalizadas (CTCG) recorrentes, incapacitantes e que colocam o paciente em risco de complicações graves. OBJETIVO: Nesse artigo é relatado o caso de um paciente com epilepsia generalizada primária e CTCG semanais, refratárias a diversos esquemas medicamentosos, que foi submetido a uma calosotomia. RESULTADO: No curto espaço de 3 meses de seguimento pós-operatório, o paciente não mais apresentou CTCG. CONCLUSÃO: A calosotomia pode ser um procedimento útil na redução da freqüência de CTCG refratárias, mesmo em pacientes com epilepsia generalizada primária.

INTRODUCTION: Patients with idiophatic generalized epilepsy (IGE) may occasionally have frequent generalized tonic-clonic seizures (GTCS) which are not adequantely controlled by antiepileptic drugs. Frequent GTCS pose a significant risk of injury and other complications. In symptomatic generalized epilepsies, corpus callosotomy (CC) has been shown to be effective in reducing the number of generalized seizures. OBJECTIVE: We report a patient with refractory, weekly GTCS in the context of a primary generalized epilepsy syndrome who underwent subtotal CC. RESULT: In the 3 months since operation, no GTCS occurred. CONCLUSION: Corpus callosotomy can be helpful in reducing medically-refractory GTCS, even in patients with primary generalized epilepsies.
