Late Onset of Neuromyelitis Optica Spectrum Disorders.

INTRODUCTION: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune demyelinating disease of the central nervous system. NMOSD starting after the age of 50 years is considered a "late onset" (LO-NMOSD) and seems to be particularly aggressive. The objective of this paper is to present a series of 37 Brazilian patients with LO-NMOSD. METHODS: Retrospective data collection from medical records of patients with LO-NMOSD seen at 14 Brazilian specialized units. RESULTS: The ratio of women to men in the sample was 4.3 to 1. The patients were followed up for a median period of 4 years. Sex, age at disease onset, and ethnic background were not associated with the number of relapses or disability outcomes. Extensive longitudinal myelitis affected 86% of patients, while optic neuritis affected 70%, and brainstem syndromes were present in only 16% of these patients. Six patients are currently using some type of support for walking or are wheelchair-bound. Three have died. Therapeutic options for NMOSD were particularly complicated for these elderly patients, since medications for controlling NMOSD are, in essence, immunosuppressive. Long-term use of corticosteroids can be an issue when the patients have high blood pressure, diabetes mellitus, or dyslipidemia (conditions often seen in elderly individuals). CONCLUSION: This series of LO-NMOSD cases highlights the importance of prompt diagnosis and treatment for these patients.

Clinical Characteristics of Patients With Neuromyelitis Optica Spectrum Disorders With Early Onset.

Neuromyelitis optica spectrum disorder is a severe and disabling disease that manifests with severe relapses of optic neuritis, longitudinally extensive myelitis, and/or brainstem syndromes. The disease is complex and, although onset typically occurs in middle age, children and adolescents may be affected. The present study adds to the literature through detailed clinical data from 36 Brazilian patients with neuromyelitis optica spectrum disorder starting before age 21. This was a retrospective assessment of medical records from 14 specialized units in Brazil. The results showed that the course of neuromyelitis optica spectrum disorder was worse in patients with disease onset before the age of 12 years. Gender and ethnic background did not influence disability accumulation. Over a median period of 8 years, 14% of the patients who presented the initial symptoms of neuromyelitis optica spectrum disorder before the age of 21 years died. In conclusion, the present study adds to the reports from other authors examining the severity of early-onset neuromyelitis optica spectrum disorder.

Clinical characteristics of 153 Brazilian patients with neuromyelitis optica spectrum disorder (NMOSD).

BACKGROUND: The 2015 criteria for diagnosing neuromyelitis optica spectrum disorder (NMOSD) have encouraged several groups across the world to report on their patients using these criteria. The disease typically manifests with severe relapses of optic neuritis, longitudinally extensive myelitis and/or brainstem syndromes, often leading to severe disability. Some patients are seropositive for antibodies against aquaporin-4 (AQP4), others are positive for anti-myelin oligodendrocyte glycoprotein (MOG), while a few are negative for both biomarkers. The disease is complex, and only now are specific therapeutic clinical trials being carried out. The present study adds to the literature through detailed clinical data from 153 medical records of Brazilian patients. METHODS: Retrospective assessment of medical records from nine specialized units in Brazil. RESULTS: NMOSD was more prevalent in females (4.1:1), who had significantly fewer relapses than males (p = 0.007) but presented similar levels of disability over time. African ancestry was associated with higher levels of disability throughout the disease course (p < 0.001), although the number of relapses was similar to that observed in white patients. Concomitant autoimmune diseases were relatively rare in this population (6.5%). Positivity for anti-AQP4 antibodies was identified in 62% of the patients tested, while 3% presented anti-MOG antibodies. Anti-AQP4 antibodies were not associated to worse disease course. The last medical record showed that six patients had died and 13 were wheelchair-bound. Seventy percent of the patients did not respond to first-line therapy (azathioprine and/or corticosteroids), and five patients continued to relapse even after four different courses of treatment. CONCLUSION: The present study adds to the reports from other countries presenting original data on Brazilian patients diagnosed with NMOSD according to the 2015 criteria.

How do we manage and treat a patient with multiple sclerosis at risk of tuberculosis?

Tuberculosis continues to be a serious health problem worldwide. The disease continues to be underdiagnosed and not properly treated. In conditions that affect the immune system, such as multiple sclerosis (MS), latent tuberculosis may thrive and reactivate during the use of immunomodulatory and immunosuppressive drugs. Among the best treatment options for patients with latent or active tuberculosis who have MS are IFN-ß, glatiramer acetate and mitoxantrone. Drugs leading to a reduced number and/or function of lymphocytes should be avoided or used with caution. Tuberculosis must always be investigated in patients with MS and treated with rigor.

Recommendations on diagnosis and treatment of depression in patients with multiple sclerosis.

Multiple sclerosis (MS) is frequently associated with depression. Yet there are few clinical trials on treating depression in MS and no agreed recommendations for its assessment and follow-up. We present evidence-based recommendations for several aspects of depression in MS, including screening for depression, recognition of other concomitant psychiatric conditions, suicide risk, disability, fatigue, cognition, adherence to treatment, the effect of drugs used to treat MS on depression and possible pharmacological treatments for depression in MS.

Multiple sclerosis starting before the age of 18 years: the Brazilian experience.

Multiple sclerosis (MS) starting in childhood and adolescence poses a challenge for diagnosis and management of the disease. The aim of the present study was to assess the characteristics of early onset MS in Brazilian patients. Methods Retrospective data collection from specialized MS units. Results From 20 MS units in 11 Brazilian states, 117 cases of MS starting before the age of 18 years were collected. These patients had an average of 10 years of disease duration, still typically with low disability and one relapse every 2.5 years. The mean age for disease onset was 13.7 years. Conclusion The present study introduces a large series of Brazilian cases of pediatric MS. Although some patients presented a very severe form of MS, on the whole the group of patients with MS starting in childhood or adolescence presented a relatively mild form of this disease in Brazil.

Neurological complications following bariatric surgery.

OBJECTIVE: It was to report on Brazilian cases of neurological complications from bariatric surgery. The literature on the subject is scarce. METHOD: Cases attended by neurologists in eight different Brazilian cities were collected and described in the present study. RESULTS: Twenty-six cases were collected in this study. Axonal polyneuropathy was the most frequent neurological complication, but cases of central demyelination, Wernicke syndrome, optical neuritis, radiculits, meralgia paresthetica and compressive neuropathies were also identified. Twenty-one patients (80%) had partial or no recovery from the neurological signs and symptoms. CONCLUSION: Bariatric surgery, a procedure that is continuously increasing in popularity, is not free of potential neurological complications that should be clearly presented to the individual undergoing this type of surgery. Although a clear cause-effect relation cannot be established for the present cases, the cumulative literature on the subject makes it important to warn the patient of the potential risks of this procedure.

OBJETIVO: Foi relatar casos de pacientes brasileiros com complicações neurológicas da cirurgia bariátrica. A literatura no assunto é escassa. MÉTODO: Foram reunidos e descritos casos atendidos por neurologistas em oito cidades brasileiras diferentes. RESULTADOS: Vinte e seis casos foram coletados neste estudo. A complicação neurológica mais frequente foi a polineuropatia axonal, mas também foram identificados casos de desmielinização central, síndrome de Wernicke, neurite óptica, radiculites, meralgia parestésica e neuropatias compressivas. Vinte e um pacientes (80%) não tiveram recuperação ou tiveram apenas recuperação parcial dos sinais e sintomas neurológicos. CONCLUSÃO: A cirurgia bariátrica, procedimento cada vez mais popularizado, não está livre de potenciais complicações neurológicas as quais deveriam ser claramente expostas aos indivíduos que a ela se submetem. Embora não possa ser estabelecida uma clara relação causa-efeito entre essa cirurgia e os sinais e sintomas referidos nos casos aqui apresentados, a literatura consultada mostrou ser importante alertar o indivíduo acerca dos riscos potenciais envolvidos nesse procedimento.

Vínculos institucionais: uma experiência asilar / Institutional linkings: an institution experience

Este trabalho pretende compreender a dinâmica das formações psíquicas dentro de uma instituição. Esta formação é constituída, ao mesmo tempo, pelo conteúdo psíquico de cada sujeito e pelo conjunto de sujeitos que formam a instituição. Tal interação se torna complexa, pois, cada indivíduo já traz internalizado um conjunto de normas, pautas e valores. Neste sentido, as autoras, através de suas vivências institucionais, e com a contribuição de autores como Kaës, Bleger e Bion, se propõem a entender as vinculações que se estabelecem no espaço psíquico da instituição e sua relação com o sofrimento institucional (AU)
