RESUMO
Introduction: The COVID-19 pandemic has had an impact on ischaemic stroke management, with a reported decrease in hospital admissions, and even disruptions in healthcare and increased in-hospital mortality. However, there is a lack of evidence on the impact of the pandemic on functional prognosis. The aim of this study is to analyse the effect of the COVID-19 pandemic on the 3-month functional outcomes of patients hospitalised due to acute ischaemic stroke in Aragon (Spain). Materil and methods: We reviewed the data of all patients admitted due to ischaemic stroke to any hospital in our regional healthcare system between 30 December 2019 and 3 May 2020. We compared modified Rankin Scale scores and mortality at 3 months in patients hospitalised before and after the declaration of a state of emergency due to the COVID-19 pandemic. Results: In total, 318 patients with acute ischaemic stroke met our inclusion criteria. No differences were observed between periods in global or specific characteristics, with the exception of a higher proportion of patients older than 80 years during the first period (42.2% vs. 29.0%, P=.028). In the comparative analysis, we found no significant differences in mortality (12.3 vs. 7.9, P=.465) or in the proportion of patients with modified Rankin Scale scores ≤ 2 (57.7% vs. 57.1%, P=.425) at 3 months. Conclusion: To our knowledge, this is the first study to analyse the impact of COVID-19 pandemic on the 3-month functional outcomes of patients with ischaemic stroke. In our region, there has been no increase in rates of mortality or disability at 3 months in patients admitted due to ischaemic stroke during the pandemic.
RESUMO
INTRODUCTION: Stroke affects around 15 million people per year, with 10%-15% occurring in individuals under 50 years old (stroke in young adults). The prevalence of different vascular risk factors and healthcare strategies for stroke management vary worldwide, making the epidemiology and specific characteristics of stroke in each region an important area of research. This study aimed to determine the prevalence of different vascular risk factors and the aetiology and characteristics of ischaemic stroke in young adults in the autonomous community of Aragon, Spain. METHODS: A cross-sectional, multi-centre study was conducted by the neurology departments of all hospitals in the Aragonese Health Service. We identified all patients aged between 18 and 50 years who were admitted to any of these hospitals with a diagnosis of ischaemic stroke or TIA between January 2005 and December 2015. Data were collected on demographic variables, vascular risk factors, and type of stroke, among other variables. RESULTS: During the study period, 786 patients between 18 and 50 years old were admitted with a diagnosis of ischaemic stroke or TIA to any hospital of Aragon, at a mean annual rate of 12.3 per 100 000 population. The median age was 45 years (IQR: 40-48 years). The most prevalent vascular risk factor was tobacco use, in 404 patients (51.4%). The majority of strokes were of undetermined cause (36.2%), followed by other causes (26.5%). The median NIHSS score was 3.5 (IQR: 2.0-7.0). In total, 211 patients (26.8%) presented TIA. Fifty-nine per cent of the patients admitted with a diagnosis of ischaemic stroke (10.3%) were treated with fibrinolysis. CONCLUSIONS: Ischaemic stroke in young adults is not uncommon in Aragon, and is of undetermined aetiology in a considerable number of cases; it is therefore necessary to implement measures to improve study of the condition, to reduce its incidence, and to prevent its recurrence.

RESUMO
INTRODUCTION: Despite the impact of cerebrovascular disease (CVD) on global health, its morbidity and time trends in Spain are not precisely known. OBJECTIVE: The purpose of our study was to characterise the epidemiology and trends pertaining to stroke in Aragon over the period 1998-2010. METHODS: We conducted a retrospective, descriptive study using the data of the Spanish health system's Minimum Data Set and included all stroke patients admitted to acute care hospitals in Aragon between 1 January 1998 and 31 December 2010. We present data globally and broken down by stroke subtype, sex, and age group. RESULTS: The number of cases increased by 13% whereas age- and sex-adjusted hospitalisation rates showed a significant decrease for all types of stroke (mean annual decrease of 1.6%). Men and women in younger age groups showed opposite trends in hospitalisation rates for ischaemic stroke. Case fatality rate at 28 days (17.9%) was higher in patients with intracerebral haemorrhage (35.8%) than in those with subarachnoid haemorrhage (26.2%) or ischaemic stroke (13%). CVD case fatality showed a mean annual decline of 2.8%, at the expense of the fatality rate of ischaemic stroke, and it was more pronounced in men than in women. DISCUSSION: Understanding stroke epidemiology and trends at the regional level will help establish an efficient monitoring system and design appropriate strategies for health planning.

INTRODUCTION: Neurological pathology as the initial form of sarcoidosis is exceptional. Neurosarcoidosis represents 5% of all cases. Central nervous system involvement is more frequent in the acute forms of this illness, whilst myositis and peripheral neuropathy are more common in chronic sarcoidosis. CLINICAL CASE: A 60 year old woman presented with peripheral facial diplegia, diminished visual acuity and bilateral papilloedema, dysarthria and unsteady gait with left lateropulsion and paresia and dysesthesia of the distal parts of the limbs. X-ray and laboratory findings were normal. Gammography with Gallium 67 citrate showed mediastimal adenopathy. Neurographic study was compatible with mixed polyneuropathy and lumbar puncture showed aseptic meningitis. The diagnosis of neurosarcoidosis was confirmed by histopathological study of the skin and sural nerve. DISCUSSION AND CONCLUSIONS: When the presenting features of sarcoidosis are neurological, as in this case, diagnosis is difficult and pathology studies showing the presence of non-caseous granulomas are essential. Biopsy of the sural nerve may be very useful. Although the pathogenesis of sarcoid neuropathology is not completely clear, finding non-caseous granulomas associated with vasculitis in the nerve biopsy indicates that both disease processes may be involved in the peripheral nerve lesion.

We describe 2 patients with myasthenia gravis and non-Hodgkin's lymphoma outside the thymus gland, in whom the two diseases progressed at different rates. Diagnosis of myasthenia gravis was based on clinical signs and compatible neurophysiologic studies, specifically by high acetylcholine antireceptor titers in the first patient and a positive Tensilon test in the second. In the first patient the clinical and serological signs of the two diseases progressed similarly. The association of these two diseases may have been the result of an underlying immunological disorder favoring their appearance, or of an immune response, caused by the lymphoma involving postsynaptic nicotinic acetylcholine receptors.

Brainstem encephalitis is an unusual infection caused by a variety of agents, among them the herpes simplex (HS) virus. The difficulty of establishing a diagnosis by neurophysiological and radiological examination is greater in this type of encephalitis than in the usual form produced by HS. We describe a fatal case of brainstem encephalitis. Inflammatory and necrotic lesions in the pous and medulla confirmed the clinical diagnosis, while the etiology was determined by immuno-histo-chemical techniques and viral culture of the cerebral parenchyma. Early diagnosis of this form of encephalitis, based on new virological techniques, allows more effective antiviral treatment.

INTRODUCTION: Systemic sclerosis (SS) is recognized as the connective tissue disease which less frequently presents neurological complications; in recent studies it is demonstrated, however, that neurological involvement in SS is more frequent of what it had been assumed. PATIENTS AND METHODS: Clinical neurological exploration was done in 26 patients with definitive SS; an electroneurogram was carried out in 23 cases in order to determine the prevalence of central neurological pathology and of peripheral neuropathy, to define its characteristics, and to investigate possible associations with clinical parameters and with autoimmunity. RESULTS: 23 cases (88%) were females and 3 cases (12%) males; the median age was 57.5 12.0 (SD) years, while the median age to the diagnosis was 51.3 12.3 (SD) years and the median period of natural history of disease was 6.2 3.1 years. Seven patients (26.9%) showed involvement of the CNS, being the headache and the neuropsychiatric manifestations the most common conditions (11.5%). Peripheral neuropathy prevalence was 39.1% (9 cases); according to the distribution of the injury, the polyneuropathy prevailed in 30.4% of cases. With regard to the functional selectivity, the sensitive-motor forms were most frequent (55.6%); according to the most involved structure, the axonal neuropathy was most common (44.4%).Discussion. The possible pathogenic mechanisms of the neurological pathology in this disease are discussed.

We report the case of a male with Buerger's disease and neurologic involvement. Cerebral arteriography showed multiple distal arterial obliterans with left-sided Moya-moya phenomena. Thromboangiitis obliterans is a chronic segmental occlusive disease affecting medium-sized and small arteries and veins throughout the body. Neurologic signs are rare, occurring in fewer than 2 % of cases, and most often found on the cortical surface and adjacent territories. We review the most common signs of this entity and its main diagnostic difficulties.
