- Myelopathy in sickle cell disease: a case-oriented review(2021) BRUM, Igor Vilela; SILVA, Guilherme Diogo; SODRE, Diego Sant'Ana; NOGUEIRA, Felipe Melo; PEREIRA, Samira Luisa dos Apostolos; CASTRO, Luiz Henrique MartinsIntroduction Although neurological complications are well recognized in patients with sickle cell disease, myelopathy has been rarely described, with few reported cases of compressive and ischemic myelopathy. We present the first case report of longitudinally extensive myelitis (LETM) in SCD and review the differential diagnosis of myelopathy in these patients. Case presentation We report the case of a 29-year-old African-Brazilian man with SCD, who experienced a subacute flaccid paraparesis, with T2 sensory level and urinary retention. Cerebrospinal fluid analysis showed a lymphocytic pleocytosis and increased protein levels. MRI disclosed a longitudinally extensive spinal cord lesion, with a high T2/STIR signal extending from C2 to T12. We searched Medline/PubMed, Embase, Scopus, and Google Scholar databases for myelopathy in SCD patients. Discussion Spinal cord compression by vertebral fractures, extramedullary hematopoietic tissue, and Salmonella epidural abscess have been reported in SCD. We found only three case reports of spinal cord infarction, which is unexpectedly infrequent compared to the prevalence of cerebral infarction in SCD. We found only one case report of varicella-zoster myelitis and no previous report of LETM in SCD patients. Specific and time-sensitive causes of myelopathy should be considered in SCD patients. In addition to compression and ischemia, LETM is a possible mechanism of spinal cord involvement in SCD patients.

- Acute chorea: case series from the emergency room of a Brazilian tertiary-level center(2021) SILVA, Guilherme Diogo; PARMERA, Jacy Bezerra; HADDAD, Monica SantoroBackground: Chorea is a movement disorder characterized by random, brief and migratory involuntary muscle contractions. It is defined as acute when present within hours to days. Three main causes for this scenario have emerged as most likely: vascular, toxic-metabolic and inflammatory. Objectives: To identify the prevalence of the main etiologies and major clinical findings of acute chorea in the emergency room of a tertiary-level referral center; and to suggest an approach for guiding the diagnostic workup and clinical management. Methods: We retrospectively reviewed the clinical aspects and neuroimaging data of 10 patients presenting with acute chorea at the neurological emergency room of our hospital from 2015 to 2019. Results: Stroke was the most common etiology (50% of the cases). All of them were ischemic. It was noteworthy that only one case demonstrated the classical ischemic topographic lesion at the contralateral subthalamic nuclei. Regarding nonvascular etiologies, nonketotic hyperglycemia was the major cause, followed by drug-related chorea. One patient showed inflammatory etiology, which was probably Sydenham chorea reactivation. Conclusion: Acute chorea is an uncommon and challenging problem at the emergency room, often associated with potentially treatable causes. We suggest that use of the acronym DANCE (Diagnosis of chorea, Acute stroke protocol, Normal glucose levels, Check neuroimaging, Exposure to drugs) could form a potential initial approach in the evaluation, in order to emphasize causes that require prompt proper management (e.g. thrombolysis).

We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases.The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

Methods The Neuroimmunology Brazilian Study Group has set up the report of severe acute respiratory syndrome (SARS-CoV2) cases in patients with NMOSD (pwNMOSD) using a designed web-based case report form. All neuroimmunology outpatient centers and individual neurologists were invited to register their patients across the country. Data collected between March 19 and July 25, 2020, were uploaded at the REDONE.br platform. Inclusion criteria were as follows: (1) NMOSD diagnosis according to the 2015 International Panel Criteria and (2) confirmed SARS-CoV2 infection (reverse transcription-polymerase chain reaction or serology) or clinical suspicion of COVID-19, diagnosed according to Center for Disease Control / Council of State and Territorial Epidemiologists (CDC/CSTE) case definition. Demographic and NMOSD-related clinical data, comorbidities, disease-modifying therapy (DMT), COVID-19 clinical features, and severity were described. Results Among the 2,061 pwNMOSD followed up by Brazilian neurologists involved on the registry of COVID-19 in pwNMOSD at the REDONE.br platform, 34 patients (29 women) aged 37 years (range 8-77), with disease onset at 31 years (range 4-69) and disease duration of 6 years (range 0.2-20.5), developed COVID-19 (18 confirmed and 16 probable cases). Most patients exhibited mild disease, being treated at home (77%); 4 patients required admission at intensive care units (severe cases); and 1 patient died. Five of 34 (15%) presented neurologic manifestations (relapse or pseudoexacerbation) during or after SARS-CoV2 infection. Discussion Most NMOSD patients with COVID-19 presented mild disease forms. However, pwNMOSD had much higher odds of hospitalization and intensive care unit admission comparing with the general Brazilian population. The frequency of death was not clearly different. NMOSD disability, DMT type, and comorbidities were not associated with COVID-19 outcome. SARS-CoV2 infection was demonstrated as a risk factor for NMOSD relapses. Collaborative studies using shared NMOSD data are needed to suitably define factors related to COVID-19 severity and neurologic manifestations.
- Study of the association between generic and disease-specific quality of life and behavior problems in pediatric patients with chronic kidney disease stage 3 or higher and the quality of life and mental health of their primary caregivers(2021) ABRAO, Renata Oliveira; LOPES, Marcos; SILVA, Guilherme J. S.; FERRARO, Alexandre A.; KOCH, Vera H.Background Chronic kidney disease (CKD) can affect quality of life and mental health of patients and their primary caregivers (PCs) in different disease stages. Methods This prospective, cross-sectional, descriptive, comparative, and analytical study of patients with stage 3-5 CKD, aged 8-18 years, assesses the association between patients' general and disease-specific health-related quality of life (HRQOL) and behavioral problems and their PCs' QoL and mental health status. PedsQL 4.0, PedsQL ESRD, CBCL, and YSR questionnaires were used to evaluate 80 patients while their PCs were assessed by SF-36 and MINI questionnaires. The study participants were divided into three groups: G1: stage 3-4 CKD, G2: peritoneal dialysis and hemodialysis, and G3: kidney transplantation. Results Lower indexes in PedsQL 4.0 and PedsQL ESRD were demonstrated in G2 patients. No deviant internalizing and/or externalizing conducts were shown by the CBCL questionnaire while the YSR questionnaire demonstrated significant differences in all domains with higher scores in G2 patients without reaching clinical range for individual syndromes. G3 PCs presented the lowest SF-36 scores and the highest occurrence of psychiatric diagnoses, according to MINI, when compared to other PCs. Parallelism was found between scores of PedsQL 4.0 and PedsQL ESRD with tendency to higher scores in the PC's view compared to the patient's view. Conclusions CKD affects HRQOL of patients and their PCs, as well as patients' behavior problems and their PCs' mental health. PCs' perceptions of patients' QOL and behavioral problems may be related to their mental health status and QOL self-perceptions.
