Crossed aphasia in a left-handed patient with non-fluent variant of primary progressive aphasia with left asymmetric brain SPECT / Afasia cruzada em paciente canhota com afasia progressiva primária variante não fluente com SPECT cerebral assimétrico à esquerda

ABSTRACT Primary progressive aphasia is a clinical syndrome caused by neurodegeneration of areas and neural networks involved in language, usually in the left hemisphere. The term "crossed aphasia" denotes an acquired language dysfunction caused by a lesion in the ipsilateral hemisphere to the dominant hand. Objective: To describe a case of crossed aphasia in a 60-year-old left-handed patient with a non-fluent variant of primary progressive aphasia diagnosis (age of onset=52), evidenced by a left asymmetry on brain SPECT scan. Methods: Clinical and family history, the Edinburgh Handedness Inventory, Measurement of Functional Activities in Older Adults in the Community, the "Mini-Mental State Examination", the Trail Making Test, the Tower of London, and the Neuropsychological assessment for dementia, and neuroimaging studies were carried out. Results: Neuropsychological assessment showed severe cognitive impairment, especially regarding language. The magnetic resonance imaging showed important signs of cortico-subcortical atrophy, with predominance in the frontal and temporal lobes. The single-photon emission computed tomography scan showed moderate to severe hypoperfusion in the left cerebral hemisphere, including the hippocampus. Conclusion: We described a clinical case of crossed aphasia in a left-handed woman with a non-fluent variant of primary progressive aphasia with asymmetry on brain SPECT, mainly on the left, followed up for seven years.

RESUMO A afasia progressiva primária é uma síndrome clínica causada por uma neurodegeneração de áreas e redes neurais envolvidas na linguagem, geralmente no hemisfério esquerdo. O termo "afasia cruzada" denota uma disfunção adquirida de linguagem causada por uma lesão no hemisfério ipsilateral da mão dominante. Objetivo: Relatamos um caso de afasia cruzada em uma paciente de 60 anos, canhota, com um quadro clínico de afasia progressiva primária variante não fluente (idade de início=52), evidenciada por assimetria no SPECT cerebral à esquerda. Métodos: Foram realizados para o diagnóstico do caso: história clínica e familiar, o Inventário de Dominância de Edinburgh, a Escala de Atividades Funcionais de Pfeffer, o Miniexame do Estado Mental, o Teste das Trilhas, o Teste da Torre de Londres, a Avaliação Neuropsicológica Adequada às Demências e exames de neuroimagem. Resultados: A avaliação neuropsicológica mostrou comprometimento cognitivo severo, principalmente sobre a linguagem; a ressonância magnética do crânio mostrou sinais de involução córtico-subcortical, com predominância nos lobos frontal e temporal e a cintilografia cerebral por emissão de fóton único mostrou hipoperfusão moderada a severa no hemisfério cerebral esquerdo, incluindo o hipocampo. Conclusão: Registramos um caso clínico de afasia cruzada em uma paciente canhota com afasia progressiva primária variante não fluente com assimetria no SPECT cerebral, principalmente à esquerda, seguida há sete anos.

Bilateral hearing loss as an initial presentation of Creutzfeldt-Jakob disease / Perda auditiva bilateral como uma apresentação inicial da doença de creutzfeldt-jakob

ABSTRACT. We reported a case of a 61-year-old male patient with anacusis, cerebellar syndrome, myoclonus, and frontal signs. The brain magnetic resonance imaging showed bilateral striated hyperintensity of the fluid-attenuated inversion recovery and restricted diffusion in the diffusion-weighted imaging and hypointense areas corresponding to the apparent diffusion coefficient in the cerebral cortex. The autopsy revealed positive immunohistochemistry for the PrPSc protein. Creutzfeldt-Jakob disease presenting with hearing loss is unusual.

RESUMO. Relatamos o caso de um paciente do sexo masculino, 61 anos, com anacusia, síndrome cerebelar, mioclonia e sinais frontais. A ressonância magnética cerebral mostrou hiperintensidade estriada bilateral do fluid-attenuated inversion recovery (FLAIR) e difusão restrita no diffusion-weighted imaging (DWI) e áreas hipointensas correspondendo ao coeficiente de difusão aparente no córtex cerebral. A autópsia revelou imuno-histoquímica positiva para a proteína PrPSc. A doença de Creutzfeldt-Jakob que se apresenta com perda auditiva é incomum.

Association between fractures and traditional risk factors for osteoporosis and low bone mineral density in patients with obesity

ABSTRACT Objective: To evaluate the reasons for request of bone mineral density (BMD) evaluation and correlate the BMD results with previous fractures, risk factors for osteoporosis, and clinical characteristics in patients with obesity. Subjects and methods: Cross-sectional, retrospective, single-site study including adult patients with body mass index (BMI) ≥ 30 kg/m2 and BMD evaluation between January 2015 and May 2016 selected from a BMD database. Data on demographic characteristics, lifestyle habits, comorbidities, medications, risk factors, previous fractures, and indications for BMD evaluation were collected from the participants' medical records. Results: The study included 619 patients (89.9% women, mean BMI 34.79 ± 4.05 kg/m2). In all, 382 (61.7%), 166 (26.8%), and 71 (11.5%) patients had class 1, 2, and 3 obesity, respectively. The most frequent (29.9%) reason for BMD evaluation was for osteoporosis monitoring. In all, 69.4% of the patients had low BMD. Multivariate analysis showed that age, calcium supplementation, and previous osteoporosis or osteopenia were associated with low BMD, while age, vitamin D supplementation, use of proton pump inhibitors (PPIs), and low BMD were associated with previous fractures (p < 0.05 for all). Conclusions: Among patients with obesity identified from a tertiary hospital database, those with low bone mass and risk factors traditionally associated with fractures had an increased history of fractures. Patients with greater BMI had better bone mass and fewer fractures. These findings indicate that the association between reduced weight, risk factors for osteoporosis, and fractures remained despite the presence of obesity in our population.

Impact of COVID-19 pandemic on the sleep quality of medical professionals in Brazil / Impacto da pandemia COVID-19 na qualidade do sono dos médicos no Brasil

ABSTRACT Introduction: Coronavirus pandemic began in China in 2019 (COVID-19), causing not only public health problems but also great psychological distress, especially for physicians involved in coping with the virus or those of the risk group in social isolation, and this represents a challenge for the psychological resilience in the world population. Studies showed that health professionals had psychological symptoms such as depression, anxiety, insomnia, stress, among others. Objectives: To investigate the quality of sleep and the prevalence rate of sleeping disorders among physicians during COVID-19 pandemic, and identify the psychological and social factors associated with the condition. Methods: A cross-sectional study of an online questionnaire was applied for physicians in Brazil. Among the 332 participants included, 227 were women. Sociodemographic assessment was used in the questionnaire, as well as the scale of impact on the events of modifications caused by COVID-19, assessment on sleep quality (PSQI), presence and severity of insomnia (ISI), depressive symptoms (PHQ-9), and anxiety (GAD-7). Results: Most physicians (65.6%) had changes in sleep. Poor sleep quality was reported by 73.1%, depressive symptoms were present in 75.8%, and anxiety in 73.4%. Conclusion: Our study found that more than 70% of the physicians assessed had impaired sleep quality, characterizing insomnia symptoms during COVID-19 outbreak. Related factors included an environment of isolation, concerns about COVID-19 outbreak and symptoms of anxiety and depression. Special interventions are needed to promote health professionals' mental well-being and implement changes in this scenario.

RESUMO Introdução: A pandemia de coronavírus iniciada na China em 2019 (COVID-19) não só causou problemas de saúde pública mas também trouxe grande sofrimento psíquico, principalmente aos médicos envolvidos no enfrentamento da doença ou àqueles do grupo de risco em isolamento social, e representa um desafio para a resiliência psicológica da população mundial. Estudos mostram que profissionais de saúde apresentaram sintomas psicológicos como depressão, ansiedade, insônia, estresse, entre outros. Objetivos: Investigar a qualidade do sono e a taxa de prevalência de transtornos do sono entre os médicos durante a pandemia do COVID-19, e identificar os fatores psicológicos e sociais associados ao quadro. Métodos: Estudo transversal com aplicação de questionário on-line a médicos do Brasil e inclusão de 332 participantes, dos quais 227 eram mulheres. Foram utilizados questionários com avaliação sociodemográfica, escala de impacto a eventos com modificações causadas pelo COVID-19, avaliação da qualidade do sono (PSQI), presença e gravidade da insônia (IGI), sintomas depressivos (PHQ-9) e ansiedade (TAG-7). Resultados: A maioria dos médicos (65,6%) apresentou alterações no sono, sendo a má qualidade do sono reportada por 73,1%. Sintomas depressivos estiveram presentes em 75,8%, e ansiedade em 73,4%. Conclusão: Nosso estudo constatou que mais de 70% dos médicos avaliados apresentavam comprometimento da qualidade do sono, caracterizando sintomas de insônia durante o surto de COVID-19. Os fatores relacionados incluíram ambiente de isolamento, preocupações com o surto de COVID-19 e sintomas de ansiedade e depressão. Intervenções especiais são necessárias para promover o bem-estar mental dos profissionais de saúde e implementar mudanças nesse cenário.

Situação vacinal de pacientes com doença inflamatória intestinal / Immunization status of patients with inflammatory bowel disease

ABSTRACT BACKGROUND: Treatment for inflammatory bowel disease (IBD) includes a variety of immunosuppressants and biological agents, which increase the risk of infections due to altered cellular and humoral immunity. Prevention of these infections can be done through vaccination, however, patients with IBD are usually under-immunized. OBJECTIVE: Analyze the immunization status of patients with IBD and confront it with the current recommendations to verify if the immunization guidelines are being followed correctly. METHODS: Analytical cross-sectional study including 239 IBD patients being regularly followed in the Gastroenterology Service from Hospital de Clínicas da Universidade Federal do Paraná, which were subjected to a survey about their relevant demographic data and immunization status. RESULTS: The amount of patients that declared being unaware of their immunization status is high - between 34.3% (Tdap) and 52% (meningococcal) - excepting IIV, hepatitis B and HPV. The vaccines with the largest rates of patients declaring to have taken it are inactivated influenza vaccine (72.4%), BCG (55.3%), hepatitis B (48.3%), measles, mumps and rubella vaccine (43.8%) and DTaP (43%). The vaccines with the lowest rates of patients declaring to have taken it are Haemophilus influenza type b (0.8%), herpes zoster (2.1%) and HPV (3.4%). Patients that are being treated or have been treated with biological therapy have the largest immunization coverage for inactivated influenza vaccine (81%) and PPSV23 (25.9%), also they have the largest awareness rates for those vaccines. CONCLUSION: Although being a specialized service linked to a university hospital, vaccination coverage and patients' awareness rates proved to be below the desirable level. Vaccination and recovery of the immunization history is recommended immediately after the diagnosis of IBD, regardless of the use of biological agents. Those findings support the need of implementing hospital guidelines and constantly verifying its application by the multidisciplinary team in specialized services in IBD.

RESUMO CONTEXTO: No tratamento de doenças inflamatórias intestinais (DII) são usados imunossupressores e agentes biológicos, o que aumenta o risco de infecções pela alteração da imunidade celular e humoral. A prevenção de algumas dessas infecções pode ser feita pela vacinação, entretanto pacientes com DII apresentam baixas taxas de cobertura vacinal. OBJETIVO: Analisar a situação vacinal de pacientes com DII e comparar com a recomendação vigente na literatura para verificar se os esquemas de imunização estão sendo corretamente aplicados nessa população. MÉTODOS: Estudo transversal analítico com 239 pacientes com DII em acompanhamento no Serviço de Gastroenterologia do Hospital de Clínicas da Universidade Federal do Paraná, os quais foram submetidos a um questionário sobre dados demográficos relevantes e sobre a situação vacinal. RESULTADOS: A taxa de pacientes que declarou não ter conhecimento de sua situação vacinal é alta - entre 34,3% (dTpa) e 52% (meningocócica) - com exceção das vacinas influenza, hepatite B e HPV. As vacinas com maior taxa de pacientes que declararam ter recebido a vacina são influenza (72,4%), BCG (55,3%), hepatite B (48,3%), tríplice viral (43,8%) e DTPa (43%). As vacinas com menor taxa de pacientes que declararam ter recebido a vacina são Haemophilus influenza b (0,8%), herpes zoster (2,1%) e HPV (3,4%). Pacientes que fazem ou já fizeram tratamento com agentes biológicos têm melhor cobertura vacinal das vacinas para influenza (81%) e PP23V (25,9%), além de maior conhecimento sobre o estado vacinal para essas vacinas. CONCLUSÃO: Apesar de se tratar de um serviço especializado ligado a um hospital universitário, a cobertura vacinal e o conhecimento dos pacientes sobre as vacinas estão abaixo do desejado. A recuperação do histórico vacinal e a recomendação das vacinas necessárias devem ser realizadas logo após o diagnóstico de DII, independentemente do uso de agentes biológicos. Esses achados indicam a necessidade da criação e monitoramento constante da aplicação de um protocolo pela equipe multidisciplinar de serviços especializados em DII.
