Post-COVID-19 olfactory dysfunction: carbamazepine as a treatment option in a series of cases.

Olfactory dysfunction is reported frequently in patients with coronavirus disease 2019. However, an effective treatment for this dysfunction is unknown. The present study evaluated carbamazepine as a treatment option for olfactory dysfunction based on its use in cases of neuralgia, especially of the V cranial nerve. The study included 10 patients with coronavirus disease with olfactory complaints who were part of a cohort of 172 coronavirus disease patients monitored for late neurological manifestations. Carbamazepine was administered for 11 weeks. The adverse effects reported were drowsiness (9/10) and dizziness (2/10); 9 of the 10 patients reported improved olfactory function after carbamazepine treatment. While the role of carbamazepine in the control of post-coronavirus disease olfactory dysfunction could not be confirmed in this study, the satisfactory response observed in most patients in this series suggests that further studies are warranted.

Assessment of health-related quality of life after mild COVID-19 infection.

INTRODUCTION: Coronavirus disease 19 (COVID-19) affected the health-related quality of life (HRQoL), and its impact on well-being is not sufficiently understood yet. The worsening of HRQoL and symptoms such as fatigue, anxiety, depression, chronic Headache, Myalgia, ageusia, olfactory disorders, and cognitive impairment can be seen in people of different ages and genders after COVID-19 infection, even mild infections without hospitalization. These issues generate a disease burden that can reduce work skills and cause social, psychological, and neuropsychiatric challenges. OBJECTIVE: To evaluate the HRQoL of patients affected by COVID-19, the domains most affected, and their relationship with fatigue, anxiety, depression, chronic Headache and Myalgia, ageusia, olfactory disorders, and cognitive impairment. METHODS: An analytical transverse was conducted with 143 patients after COVID-19 infection. The patient-reported outcomes measures (PROMS) were collected by the 36-item Short Form survey (SF-36), Fatigue Severity Scale (FSS), Hospital Anxiety and Depression Scale (HADS), Mini-Mental State Examination-2 (MMSE-2), Symbol Digit Modalities Test (SDMT), and a questionnaire regarding symptoms such as chronic Headache, myalgia, and olfactory disorders. Spearman's correlation test was used to correlate the performance of the patients on different PROMS. RESULTS: Fatigue, depression, and anxiety were negatively correlated with all the SF-36 domains, and patients with subjective cognitive complaints had low scores in all SF-36 domains. Furthermore, those with chronic Headaches had low scores in physical functioning, role-physical functioning, and vitality. Regarding myalgia complaints, the worst scores were observed in the physical functioning and vitality domains. Patients with ageusia had low scores in general health perceptions, and those with olfactory dysfunction had low scores in the vitality and mental health domains. CONCLUSIONS: Although the acute phase of COVID-19 has resolved, knowledge about HRQoL after this period is essential since many individual and collective changes have been taking place until today-patients with neuropsychiatric manifestations that persisted after the acute phase showed lower overall quality of life.

Cognitive Complaints Assessment and Neuropsychiatric Disorders After Mild COVID-19 Infection.

OBJECTIVES: This study aimed to analyze cognitive impairment associated with long-term coronavirus disease 2019 (COVID-19) syndrome and its correlation with anxiety, depression, and fatigue in patients infected with severe acute respiratory syndrome coronavirus. METHODS: This was a cross-sectional study of 127 patients with COVID-19. Tests to screen for neuropsychiatric symptoms included the Fatigue Severity Scale, Mini-Mental State Exam 2 (MMSE-2), Symbol Digit Modalities Test (SDMT), and Hospital Anxiety and Depression Scale. RESULTS: In cognitive tests, SDMT was abnormal in 22%, being more sensitive than MMSE-2 to detect cognitive changes. Furthermore, although manifestations such as fatigue, depression, and anxiety were frequent in the post-COVID-19 phase, these 3 conditions, known to contribute to cognitive impairment, were slightly correlated with worse performance on the rapid screening tests. CONCLUSIONS: In patients with mild COVID-19 and cognitive complaints, SDMT helped to confirm disturbances in the attention domain and processing speed.

Accuracy of the Brazilian version of the DYMUS questionnaire for the screening of oropharyngeal dysphagia in multiple sclerosis.

BACKGROUND: Oropharyngeal dysphagia is a common symptom of many neurological diseases, including Multiple Sclerosis (MS). Early identification of the risk of dysphagia in neurological patients is very important for early referral for specialized evaluations of oropharyngeal swallowing and treatments. The Dysphagia in Multiple Sclerosis (DYMUS) questionnaire has been translated and validated in different countries over the last 10 years. We aimed to analyze the accuracy of the Brazilian Portuguese version of the DYMUS (DYMUS-BR) questionnaire in identifying dysphagia in patients with MS. METHODS: The DYMUS questionnaire and a videofluorographic swallowing study (VFSS) were conducted in 30 patients with MS. Dysphagia was identified by at least one abnormal response and was considered alarming when the DYMUS scores were equal to or higher than 3. Patients were considered to have dysphagia in the VFSS when one or more signs of impairment in the efficiency and/or safety of swallowing were detected. RESULTS: According to the initial self-assessment, 37% (N = 11) of patients with MS self-reported with dysphagia. According to the DYMUS-BR scores, 53% (N = 16) of the patients with MS were classified as having dysphagia. The sensitivity, specificity, and positive and negative predictive values of the DYMUS-BR questionnaire for the detection of dysphagia as measured by the VFSS were 50% [95% confidence interval (CI) 29-71], 78% (95% CI 61-90), 60% (95% CI 42-76), and 70% (95% CI 60-78), respectively. The area under the receiver-operating characteristic curve for detecting dysphagia was 64% (95% CI 49-79). CONCLUSION: The accuracy of the DYMUS-BR questionnaire is poor to detect mild swallowing impairment in patients with MS. However, we suggest longitudinal follow-up in patients with low DYMUS-BR scores for early detection of oropharyngeal dysphagia.

Xantomatose cerebrotendínea: uma doença rara e multissistêmica ainda pouco conhecida. Quando devemos suspeitar? / Cerebrotendinous xanthomatosis: a rare and multisystemic disease still little known. When should we suspect?

Xantomatose cerebrotendínea (XCT) é uma doença congênita autossômica recessiva rara multissistêmica do me-tabolismo do ácido biliar que leva ao acúmulo de intermediários do colesterol em diversos tecidos. A principal ma-nifestação da doença é o acometimento neurológico progressivo e irreversível, que inicia na infância e evolui com disfunção neurológica grave na fase adulta. Sintomas não neurológicos característicos como xantomas tendíneos, cataratas de início na infância e diarreia crônica infantil também podem estar presentes. No Brasil, não existe te-rapia medicamentosa para a doença. A principal abordagem terapêutica para retardar a progressão do quadro é o acompanhamento multidisciplinar com o objetivo de melhorar a qualidade de vida. Apesar dos sintomas iniciarem na infância, a maioria dos pacientes demora em média 16 anos para receber o diagnóstico, fase na qual o dano neurológico já é extenso e as abordagens terapêuticas não são mais eficazes. Neste estudo é relatado o caso de paciente de 47 anos com XCT que iniciou os sintomas na infância, com piora neurológica aos 38 anos e diagnóstico aos 44 anos, fase na qual a neurodegeneração já era grave e irreversível. Os testes laboratoriais e Imagem de Res-sonância Magnética indicaram alterações características da doença. Ressalta-se a importância de ter a XTC como diagnóstico diferencial na presença de um quadro neurológico progressivo, amplo e variado, associado com xanto-mas tendíneos e outros sinais e sintomas específicos. Por tratar-se de doença crônica e degenerativa, o diagnóstico precoce é essencial para que se possa instituir medidas que melhorem a qualidade de vida (AU)

Cerebrotendinous xanthomatosis (CTX) is a rare, multisystemic autosomal-recessive disease of biliary acid me-tabolism that leads to accumulation of cholesterol intermediates in multiple tissues. Its primary presentation is progressive and irreversible neurological damage, beginning in childhood and progressing to neurological dys-function in adulthood. There also are characteristic non-neurological symptoms, including tendinous xanthomas, cataracts beginning in childhood, and chronic infantile diarrhea. In Brazil, there is no available treatment for CTX. The primary therapeutic approach to slow disease progression is a palliative one, with multidisciplinary team. While CTX symptoms begin in childhood, most patients are diagnosed at approximately age 16, when neurological damage is extensive and therapeutic approaches are no longer effective. Here, we report a case of a 47-year-old female patient with CTX with symptoms beginning in childhood, with neurological worsening at the age of 38 and diagnosis at 44, at which neurodegeneration was already severe and irreversible. Laboratory tests and magnetic resonance imaging indicated characteristic symptoms. It is important to consider CTX as a differential diagnosis in the presence of a progressive, wide, and varied neurological picture, with tendinous xanthomas and other specific symptoms. Because it is a chronic and degenerative disease, early diagnosis is essential to establish measures to improve the quality of life (AU)
