RESUMO

BACKGROUND: Low bone mineral density (BMD) and vertebral fractures (VF) have been associated with atherosclerosis in the general population. We sought to investigate the relationship between BMD and VF and carotid atherosclerosis in women with systemic lupus erythematosus (SLE). METHODS: We studied 122 women with SLE. All patients had BMD, carotid intima-media thickness (IMT), and carotid artery atherosclerotic plaque assessment by ultrasound. RESULTS: Mean age at study entry was 44 years and mean disease duration was 11 years. Carotid plaque was found in 13 (11%) patients (9 postmenopausal and 4 premenopausal). Patients in the highest IMT quartile were more likely to be older (p = 0.001), have a higher body mass index (p = 0.008), and exhibit dyslipidemia at study entry (p = 0.041), compared with the lower three quartiles. BMD at the lumbar spine was lower in patients in the highest IMT quartile compared with the lower quartiles in the multivariate logistic analysis, however, there was no association between lumbar or total hip BMD and IMT (p = 0.91 and p = 0.6, respectively). IMT measurements did not differ according to the presence or absence of VF (0.08 ± 0.12 vs. 0.06 ± 0.03 mm, p = 0.11). A trend towards higher incidence of VF was found in patients with carotid plaque compared with those without (33% vs. 21%; p = 0.2). CONCLUSIONS: In patients with SLE, the presence of carotid atherosclerosis is not associated with low BMD or VF.

RESUMO

Fourier Transform Infrared (FTIR) micro-spectroscopy measurements were acquired to study infrared signatures of chemotherapeutic response as a function of the cell cycle. Renal carcinoma Caki-2 cells were exposed to IC50 doses of 5-fluorouracil and Paclitaxel for a period of 24 hours. The inherent cell cycle infrared signatures from untreated and drug-treated cells were successfully retrieved by the construction of a robust SVM able to discriminate the cell cycle phases of this cell line with an average accuracy of 83.7%. The overriding infrared signature observed relates to an apoptotic biochemical response that does not appear to be correlated with the events affected by the drugs' mode of action or the cell cycle. Since apoptosis is a well conserved mechanism among living species, these results suggest that both the stages of proliferation as well as the absence/presence of apoptosis need to be taken into account in order to elucidate the fine biochemical details revealing the immediate cellular response to the drug in order to assign reliable spectral patterns of drug action.

RESUMO

A new optical system has recently been developed that enables infrared images to be obtained with a pixel resolution of 1 micron on a bench-top instrument using a thermal source. We present here imaging data from two contrasting cellular systems that represent different challenges. Renal carcinoma cells cytospun onto CaF2 have a largely rounded morphology and thus suffer from strong resonant Mie scattering. Skin fibroblast cells, cultured onto CaF2 on the other hand are very spread out so scatter less strongly but are so thin they deliver extremely weak signals. Using suitable pre-processing methods, including PCA noise reduction and RMieS correction, we demonstrate that useful high resolution images can be obtained from either sample.

RESUMO

INTRODUCTION: Post-stroke depression (PSD) is the most common mood disorder following a stroke, and also the main factor limiting recovery and rehabilitation in stroke patients. In addition, it may increase mortality by up to ten times. DEVELOPMENT: PSD occurs in 1 in 3 stroke patients and more than half of all cases are neither diagnosed nor treated. Several mechanisms, including biological, behavioral, and social factors, are involved in its pathogenesis. Symptoms usually occur within the first three months after stroke (early onset PSD), and less frequently at a later time (late onset PSD). Symptoms resemble those of other types of depression, although there are some differences: PSD patients experience more sleep disturbances, vegetative symptoms, and social withdrawal. For PSD diagnosis, we recommended vigilance and use of specific diagnostic tools such as the Patient Health Questionnaire-2 (PHQ-2). The treatments of choice are selective serotonin reuptake inhibitors (SSRI). However, there are still many unanswered questions in the treatment of PSD, such as the best time to start treatment or the effects of antidepressants on cognition and motor function, among others. CONCLUSIONS: Neurologists play a pivotal role in the care and management of patients recovering from stroke. They must be familiar with methods for early detection and treatment of PSD, as this can facilitate a patient's functional recovery and social reintegration, and improve quality of life for patients and their families.

RESUMO

INTRODUCTION: Hypnic headache is a rare primary headache. The diagnostic criteria of the International Headache Classification (IHS) for this condition are discussed, as they have been modified in the new edition of the 2013. PATIENTS AND METHODS: The clinical characteristics, and fulfilment of the criteria of the IHS classification in a series of 10patients diagnosed in our Headaches Clinic, are analyzed. RESULTS: The mean age of onset of symptoms was 52.1years (SD: 13.4; range: 28-69). The pain was reported as oppressive in 60% of the patients, and as sharp in 30%. The headache was described as holocranial in 60% and hemicranial in 40%. They occurred exclusively during night-time sleep in 80% of the patients. The mean duration of headache was 136.5minutes (range: 10-480). The mean number of days per month was 16.4 (range: 3-30), and 50% had less than 15 headache days per month. No patient had autonomic manifestations, 70% had phonophobia, 50% had photophobia, and 50% had both. All of them (100%) had a VAS score equal to or higher than 8. CONCLUSIONS: The criteria for hypnic headache of the new classification are best suited to the characteristics of these patients. Our results show the major changes in the criteria: pain is not always dull, headache frequency may be less than 15days a month, and it can occur in people under age 50. There may be phonophobia or photophobia only, or both. Although it does not form part of the diagnostic criteria, the pain intensity in our series was higher than described.

RESUMO

The objective of this study was to assess the effects of rituximab on bone mineral density (BMD) in women with systemic lupus erythematosus (SLE) 1 year after treatment. Thirty active female SLE patients treated with rituximab were compared with 43 SLE women not treated with rituximab. BMD was measured using dual energy X-ray absorptiometry (DEXA) before initiating biologic therapy and after 1 year. The mean age was 38.5 ± 2.1 years; median disease duration was 7 years. In the rituximab group, after 1 year of follow-up, BMD at the femoral neck (FN) decreased from 0.980 ± 0.130 g/cm(2) to 0.809 ± 0.139 g/cm(2) (-17.4%; p=0.001). Similarly, BMD at the lumbar spine (LS) decreased from 1.062 ± 0.137 g/cm(2) to 0.893 ± 0.194 g/cm(2) (-15.8%; p=0.001). In control subjects, BMD at the FN decreased from 0.914 ± 0.193 g/cm(2) to 0.890 ± 0.135 g/cm(2) (-2.6%; p=0.001), and BMD at the LS decreased from 0.926 ± 0.128 g/cm(2) to 0.867 ± 0.139 g/cm(2) (-6.2%; p=0.09). After 1 year, SLE patients had lower BMD at both the FN and LS, but the loss was greater in postmenopausal patients who had received rituximab therapy.

RESUMO

FTIR micro-spectral images of Caki-2 cells cytospun onto calcium fluoride (CaF2) slides were used to build a computational model in order to discriminate between the biochemical events of the continuous cell cycle during proliferation. Multivariate analysis and machine learning techniques such as PCA, PLSR and SVMs were used to highlight the chemical differences among the cell cycle phases and also to point out the need for removing the distortion of the spectra due to the morphology of the cells. Results showed cell cycle dependant scattering profiles that enabled the training of a SVM in order to recognise, with a relative high accuracy, each cell cycle phase purely with the scattering curve removed from the FTIR data after being subject to the RMieS-EMSC algorithm.

RESUMO

INTRODUCTION: Population aging has caused an increase in strokes in very elderly patients (VEP). We assess how secondary prevention of ischemic stroke has changed in VEP in recent decades. METHOD: Retrospective study of discharges due to ischemic stroke in the Virgen Macarena, Virgen del Rocio and Valme hospitals in Seville (Spain), during the periods 1999-2001, 2014-16 and 2019-2020. VEP were considered those with ≥80 years. RESULT: We studied 1806 patients, 349 (19.3%) were VEP. Over the years, VEPs have doubled (13.5% vs. 25.9% and 28% p = 0.0001) and age has increased (83.3 ±â€¯3 vs. 84.1 ±â€¯3 vs. 85.2 ±â€¯4 p = 0.001). Comparing the periods, the VEPs have more hypertension (69.9% vs. 84.8% vs. 84.6%; p = 0.0001) and dyslipidemia (12% vs. 41.7% vs. 52.3%; p = 0.0001) and have prescribed more antihypertensives (69.1% vs. 86.7% vs. 92.3%; p = 0.0001), statins (5.3% vs. 78% vs. 81.5%; p = 0.0001) and anticoagulants (16.5% vs. 19.4% vs. 53.1%; p = 0.001), increasing the number of antihypertensives (1 ±â€¯0.9 vs. 1.6 ±â€¯0, 9 vs. 1.9 ±â€¯0.8 drugs p = 0.0001), and high-intensity statins (2.3% vs. 42.7 vs. 69.2% p = 0.0001). Comparing the VEPs with the younger ones, there were no differences in antihypertensive treatment in any period, there were differences in antithrombotic treatment in the first period, and with statins the differences were maintained until the end. CONCLUSIONS: In the last 20 years the number of VEPs has doubled, exceeding a quarter of the discharges. Although there is improvement in secondary stroke prevention in VEPs, there is room for improvement.

RESUMO

INTRODUCTION: New-onset super-refractory status epilepticus (NOSRSE) is a neurological emergency characterised by the development of status epilepticus in a patient without epilepsy or any known prior neurological disease and with no clear structural, toxic or metabolic cause, which recurs after 24 hours of induced coma. The most common identifiable cause is inflammatory-autoimmune. Consequently, we present a case of NOSRSE related to SARS-CoV-2 vaccination as an opportunity to investigate the dysimmune origin of this pathology. CASE REPORT: We report the case of a 40-year-old male who presented at the emergency department with fever and headache with no clear source of infection. His personal history included bacterial meningitis in childhood without any sequelae and protein S deficiency without treatment at the time, as well as vaccination with ChAdOx1 nCoV-19 21 days earlier. He was initially diagnosed with a urinary tract infection and treated with cefuroxime. Two days later, he was taken back to the emergency department with confusional symptoms and tonic-clonic seizures. He did not respond to midazolam and finally required sedation and orotracheal intubation for refractory status epilepticus. While in hospital, he required a number of lines of antiepileptic drugs, ketamine, a ketogenic diet, immunotherapy and plasmapheresis in order to successfully limit NOSRSE. The aetiological study offered normal results for serology, antineuronal antibodies in serum and cerebrospinal fluid, transthoracic echocardiography, testicular ultrasound and computed tomographic angiography. Only the control MRI scan showed a diffuse and bilateral alteration of the right hemispheric cortex and thalamic pulvinar as the only finding. CONCLUSION: It is crucial to report suspected adverse reactions associated with SARS-CoV-2 vaccination, thereby allowing continued monitoring of the risk/benefit ratio of vaccination.


TITLE: Estado epiléptico superrefractario de nueva aparición criptógeno tras vacunación contra el SARS-CoV-2. A propósito de un caso.Introducción. El estado epiléptico superrefractario de nueva aparición (NOSRSE) es una emergencia neurológica caracterizada por el desarrollo de estado epiléptico en un paciente sin epilepsia ni enfermedad neurológica previa conocida y sin clara causa estructural, tóxica o metabólica, que recurre tras 24 horas del coma inducido. La causa identificable más frecuente es la inflamatoria-autoinmune. En consecuencia, planteamos un caso de NOSRSE relacionado con la vacunación para el SARS-CoV-2 como una oportunidad de indagar el origen disinmune de esta patología. Caso clínico. Varón de 40 años que acude al servicio de urgencias refiriendo fiebre y cefalea sin claro foco infeccioso. Entre sus antecedentes personales destacamos una meningitis bacteriana en la infancia sin secuelas y un déficit de proteína S sin tratamiento en ese momento, así como vacunación con ChAdOx1 nCoV-19 21 días antes. Fue inicialmente diagnosticado de infección del tracto urinario y tratado con cefuroxima. Dos días después, se le llevó de nuevo a urgencias con cuadro confusional y crisis tonicoclónicas, sin respuesta al midazolam, y requirió finalmente sedación e intubación orotraqueal por estado epiléptico refractario. Durante su ingreso requirió múltiples líneas de antiepilépticos, quetamina, dieta cetógena, inmunoterapia y plasmaféresis para conseguir limitar el NOSRSE. El estudio etiológico ofrecía normalidad de los resultados de serología, anticuerpos antineuronales en el suero y líquido cefalorraquídeo, ecocardiografía transtorácica, ecografía testicular y angiotomografía computarizada. Únicamente la resonancia magnética de control mostró una alteración difusa y bilateral de la corteza hemisférica y pulvinar talámica derecha como único hallazgo. Conclusión. Es crucial notificar las sospechas de reacciones adversas asociadas a la vacunación frente al SARS-CoV-2, permitiendo así una supervisión continuada de la relación riesgo/beneficio de ésta.

RESUMO

INTRODUCTION: The role of statins after ischaemic stroke changed with the publication of the SPARCL study in 2006. We analyse how this has influenced the prescription of statins in this patient population. METHODS: We conducted a retrospective study of patients discharged with ischaemic stroke at the Virgen Macarena, Virgen del Rocío, and Valme hospitals in Seville (Spain) over two periods: 1999-2001 and 2014-2016. RESULTS: The study included 1575 patients: 661 (42%) were women and mean age (standard deviation) was 69 (10) years. Patients from the later period are older (68 [10] vs 71 [11]; P = .0001); include a higher proportion of women; and present higher rates of dyslipidaemia, hypertension, and diabetes. At discharge, statins were used in 18.7% of patients (vs 86.9% in the first period; P = .0001), with high-intensity statins prescribed in 11.1% of cases (vs 54.4%; P = .0001). In both periods, atorvastatin was the most commonly prescribed statin (80 mg: 6% vs 42.7%; 40 mg: 5.1% vs 11.1%). In the first period, the use of statins and high-intensity statins was correlated with hypercholesterolaemia, and inversely correlated with age. In the second period, statin use was correlated with hypertension and hypercholesterolaemia, and high-intensity statin use was correlated with ischaemic heart disease and inversely correlated with age. CONCLUSION: There has been a clear change in the prescription of statins to patients with ischaemic stroke at discharge. However, many patients remain undertreated and the use of these drugs needs to be optimised.

RESUMO

INTRODUCTION AND OBJECTIVE: Headache is a frequent reason for consultation between primary care physicians, emergency services physicians, and neurology specialists; however, it is not always well managed. The Andalusian Society of Neurology's Headache Study Group (SANCE) aimed to analyse headache management at different levels of care. MATERIAL AND METHODS: We conducted a descriptive cross-sectional study with data gathered through a retrospective survey in July 2019. Participants completed a series of structured questionnaires on different social and work-related variables from 4 different groups of healthcare professionals (primary care [PC], emergency departments, neurology departments, headache units). RESULTS: A total of 204 healthcare professionals completed the survey: 35 emergency department physicians, 113 PC physicians, 37 general neurologists, and 19 neurologists specialising in headache. Eighty-five percent of PC physicians reported prescribing preventive drugs, which were maintained for at least 6 months (59%), with flunarizine and amitriptyline being the most commonly used. Most patients attended at neurology consultations (65%) are referred by PC physicians, with changes in the headache pattern being the main reason for referral (74%). Healthcare professionals across all levels of care showed great interest in headache and in receiving training in headache management (97% of PC physicians, 100% of emergency services physicians, 100% of general neurologists). CONCLUSIONS: Migraine sparks great interest among healthcare professionals from different levels of care. Our results also reveal a lack of resources for headache management, which is reflected in the long waiting times. Other means of bilateral communication between different levels of care should be explored (eg, e-mail).

RESUMO

INTRODUCTION: The training period in neurophysiology is a substantial part of the Neurology Specialist Program in Spain. The National Neurology Committee (La Comisión Nacional de Neurología (CNN), which is the body reporting to the Ministries of Health and Education, must ensure compliance to the Program. MATERIAL AND METHODS: During the first trimester of 2008, the CNN sent a questionnaire, in which there was a question asking about this training period, to each of the managers of the 69 teaching units accredited for neurology training in Spain, for them to answer. RESULTS: Of the 69 questionnaires issued, 49 were received completed, which was a response rate of 71%. The neurophysiology training period of the neurology specialist program in Spain was carried out in the same hospital in 44 teaching unit (90%): the remaining 5 sent their neurology trainees to 4 different hospitals. The Unit that carried out the neurophysiology training period was incorporated into the Neurology Department in 27 (55%) cases, and the formula was mixed in 3 (6%). A total of 69% of tutors were satisfied with the training, but was 90% in the hospitals where the unit was integrated into Neurology, and was 65% where this relationship did not exist. The neurologists in training were informed about EEG in 49% of education units, performed EMG/ENG 57%, and informed about evoked potentials in 35% after their training period. CONCLUSIONS: Although the level of satisfaction is high, the level of responsibility assumed by the neurologists in training during their rotation into neurophysiology does not appear to comply to the demands laid out in the training program, particularly in these units not integrated into Neurology Departments.

RESUMO

The objective of this study was to investigate the efficacy and safety of anti-CD20 treatment in Hispanic patients with refractory systemic lupus erythematosus and to determine whether baseline parameters predict disease flare. Fifty-two patients with systemic lupus erythematosus, 13 with active lupus nephritis, eight with thrombocytopenia, three with leukocytopenia, 25 with severe musculoskeletal involvement and three with skin involvement) refractory to conventional therapy were treated with anti-CD20 treatment (rituximab; MabThera, Roche) plus ongoing immunosuppressive treatment. Disease activity was assessed monthly using the SLEDAI validated for the Mexican population with a follow-up period of 6 months. At 6 months of follow-up, significant clinical improvements were detected, with a reduction in the global SLEDAI validated for the Mexican population score. Five of the 13 patients with lupus nephritis (38.4%) had a complete renal response and five (38.4%) had a partial response. Rituximab was also effective in patients with autoimmune thrombocytopenia, inducing a significant increase in platelet counts (p = 0.012). Nineteen of 25 patients with severe musculoskeletal involvement had remission of arthritis. Only one of the three patients with skin involvement had no lesions at 6 months. Rituximab treatment also allowed a reduction of the oral prednisone dose in the majority of patients. No baseline predictors of flare were found. Treatment was discontinued after the first infusion in two patients due to serum sickness and in another due to pulmonary infection. In conclusion, the addition of rituximab to conventional immunosuppressive therapy may be an effective strategy for lupus nephritis, autoimmune thrombocytopenia and inflammatory polyarthritis in patients with refractory systemic lupus erythematosus.

RESUMO

INTRODUCTION: SARS-CoV-2 was first detected in December 2019 in the Chinese city of Wuhan and has since spread across the world. At present, the virus has infected over 1.7 million people and caused over 100 000 deaths worldwide. Research is currently focused on understanding the acute infection and developing effective treatment strategies. In view of the magnitude of the epidemic, we conducted a speculative review of possible medium- and long-term neurological consequences of SARS-CoV-2 infection, with particular emphasis on neurodegenerative and neuropsychiatric diseases of neuroinflammatory origin, based on the available evidence on neurological symptoms of acute SARS-CoV-2 infection. DEVELOPMENT: We systematically reviewed the available evidence about the pathogenic mechanisms of SARS-CoV-2 infection, the immediate and lasting effects of the cytokine storm on the central nervous system, and the consequences of neuroinflammation for the central nervous system. CONCLUSIONS: SARS-CoV-2 is a neuroinvasive virus capable of triggering a cytokine storm, with persistent effects in specific populations. Although our hypothesis is highly speculative, the impact of SARS-CoV-2 infection on the onset and progression of neurodegenerative and neuropsychiatric diseases of neuroinflammatory origin should be regarded as the potential cause of a delayed pandemic that may have a major public health impact in the medium to long term. Cognitive and neuropsychological function should be closely monitored in COVID-19 survivors.

RESUMO

INTRODUCTION: The COVID-19 pandemic will give rise to long-term changes in neurological care, which are not easily predictable. MATERIAL AND METHODS: A key informant survey was used to enquire about the changes expected in the specialty over the next 5 years. The survey was completed by heads of neurology departments with broad knowledge of the situation, having been active during the pandemic. RESULTS: Despite a low level of consensus between participants, there was strong (85%) and moderate consensus (70%) about certain subjects, mainly the increase in precautions to be taken, the use of telemedicine and teleconsultations, the reduction of care provided in in-person consultations to avoid the presence of large numbers of people in waiting rooms, the development of remote training solutions, and the changes in monitoring visits during clinical trials. There was consensus that there would be no changes to the indication of complementary testing or neurological examination. CONCLUSION: The key informant survey identified the foreseeable changes in neurological care after the pandemic.

RESUMO

INTRODUCTION: The role of statins after ischaemic stroke changed with the publication of the SPARCL study in 2006. We analyse how this has influenced the prescription of statins in this patient population. METHODS: We conducted a retrospective study of patients discharged with ischaemic stroke at the Virgen Macarena, Virgen del Rocío, and Valme hospitals in Seville (Spain) over two periods: 1999-2001 and 2014-2016. RESULTS: The study included 1575 patients: 661 (42%) were women and mean age (standard deviation) was 69 (10) years. Patients from the later period are older (68 [10] vs 71 [11]; P=.0001); include a higher proportion of women; and present higher rates of dyslipidaemia, hypertension, and diabetes. At discharge, statins were used in 18.7% of patients (vs 86.9% in the first period; P=.0001), with high-intensity statins prescribed in 11.1% of cases (vs 54.4%; P=.0001). In both periods, atorvastatin was the most commonly prescribed statin (80mg: 6% vs 42.7%; 40mg: 5.1% vs 11.1%). In the first period, the use of statins and high-intensity statins was correlated with hypercholesterolaemia, and inversely correlated with age. In the second period, statin use was correlated with hypertension and hypercholesterolaemia, and high-intensity statin use was correlated with ischaemic heart disease and inversely correlated with age. CONCLUSION: There has been a clear change in the prescription of statins to patients with ischaemic stroke at discharge. However, many patients remain undertreated and the use of these drugs needs to be optimised.

RESUMO

The habits and lifestyles are the fundamental factors in the control of cardiovascular risk. Patients who have had a cerebrovascular accident (CVA) have a high risk of having a new event with similar characteristics. The exponentially growing success, penetration and adherence of the new communication technologies, based on applications (APPs), allows to use them to obtain information and influence the risk factors. We propose that empowering patients in their disease can make a more efficient management of it. For this reason, we designed and developed a system which integrates a mobile application and a web application. This system also makes use of peripheral devices to monitor patients and allow the automatic acquisition of information to enable the characterization of this kind of patients in relation to habits and lifestyle. At the same time, the system can also empower these patients with their disease to do secondary prevention.

RESUMO

Introduction: New-onset super-refractory status epilepticus (NOSRSE) is a neurological emergency characterised by the development of status epilepticus in a patient without epilepsy or any known prior neurological disease and with no clear structural, toxic or metabolic cause, which recurs after 24 hours of induced coma. The most common identifiable cause is inflammatory-autoimmune. Consequently, we present a case of NOSRSE related to SARS-CoV-2 vaccination as an opportunity to investigate the dysimmune origin of this pathology. Case report: We report the case of a 40-year-old male who presented at the emergency department with fever and headache with no clear source of infection. His personal history included bacterial meningitis in childhood without any sequelae and protein S deficiency without treatment at the time, as well as vaccination with ChAdOx1 nCoV-19 21 days earlier. He was initially diagnosed with a urinary tract infection and treated with cefuroxime. Two days later, he was taken back to the emergency department with confusional symptoms and tonic-clonic seizures. He did not respond to midazolam and finally required sedation and orotracheal intubation for refractory status epilepticus. While in hospital, he required a number of lines of antiepileptic drugs, ketamine, a ketogenic diet, immunotherapy and plasmapheresis in order to successfully limit NOSRSE. The aetiological study offered normal results for serology, antineuronal antibodies in serum and cerebrospinal fluid, transthoracic echocardiography, testicular ultrasound and computed tomographic angiography. Only the control MRI scan showed a diffuse and bilateral alteration of the right hemispheric cortex and thalamic pulvinar as the only finding. Conclusion: It is crucial to report suspected adverse reactions associated with SARS-CoV-2 vaccination, thereby allowing continued monitoring of the risk/benefit ratio of vaccination.(AU)


Introducción: El estado epiléptico superrefractario de nueva aparición (NOSRSE) es una emergencia neurológica caracterizada por el desarrollo de estado epiléptico en un paciente sin epilepsia ni enfermedad neurológica previa conocida y sin clara causa estructural, tóxica o metabólica, que recurre tras 24 horas del coma inducido. La causa identificable más frecuente es la inflamatoria-autoinmune. En consecuencia, planteamos un caso de NOSRSE relacionado con la vacunación para el SARS-CoV-2 como una oportunidad de indagar el origen disinmune de esta patología. Caso clínico: Varón de 40 años que acude al servicio de urgencias refiriendo fiebre y cefalea sin claro foco infeccioso. Entre sus antecedentes personales destacamos una meningitis bacteriana en la infancia sin secuelas y un déficit de proteína S sin tratamiento en ese momento, así como vacunación con ChAdOx1 nCoV-19 21 días antes. Fue inicialmente diagnosticado de infección del tracto urinario y tratado con cefuroxima. Dos días después, se le llevó de nuevo a urgencias con cuadro confusional y crisis tonicoclónicas, sin respuesta al midazolam, y requirió finalmente sedación e intubación orotraqueal por estado epiléptico refractario. Durante su ingreso requirió múltiples líneas de antiepilépticos, quetamina, dieta cetógena, inmunoterapia y plasmaféresis para conseguir limitar el NOSRSE. El estudio etiológico ofrecía normalidad de los resultados de serología, anticuerpos antineuronales en el suero y líquido cefalorraquídeo, ecocardiografía transtorácica, ecografía testicular y angiotomografía computarizada. Únicamente la resonancia magnética de control mostró una alteración difusa y bilateral de la corteza hemisférica y pulvinar talámica derecha como único hallazgo. Conclusión: Es crucial notificar las sospechas de reacciones adversas asociadas a la vacunación frente al SARS-CoV-2, permitiendo así una supervisión continuada de la relación riesgo/beneficio de ésta.(AU)

RESUMO

Introducción: El papel de las estatinas tras el ictus isquémico cambió con la publicación del estudio SPARCL en 2006. Nos planteamos valorar cómo ha influido en la prescripción de estatinas en esta población.MétodoEstudio retrospectivo de las altas por ictus isquémico en los hospitales Virgen Macarena, Virgen del Rocío y Valme de Sevilla durante dos periodos: 1999-2001 y 2014-2016.ResultadoIncluimos 1.575 pacientes, 661 (42%) mujeres, edad media 69 (± 10) años. Comparando los dos períodos, los pacientes del grupo post-SPARCL tienen mayor edad (68 ± 10 vs. 71 ± 11, p = 0,0001), mayor proporción de mujeres y mayor frecuencia de dislipidemia, hipertensión y diabetes. Al alta se utilizaron estatinas en el 18,7% frente al 86,9% (p = 0,0001), y estatinas de alta intensidad en el 11,1% frente al 54,4% (p = 0,0001), respectivamente. En ambos períodos la atorvastatina fue la estatina más recetada (80 mg, 6% vs. 42,7%; 40 mg, 5,1% vs. 11,1%). En el primer grupo, el uso de estatinas y de estatinas de alta intensidad se correlacionó con la hipercolesterolemia, y de forma inversa con la edad. En el segundo grupo, el uso de estatinas se correlacionó con la hipertensión y la hipercolesterolemia, y el de estatinas de alta intensidad, con la cardiopatía isquémica y, de forma inversa, con la edad.ConclusiónExiste un cambio evidente en la prescripción de estatinas al alta en pacientes con ictus isquémico. No obstante, muchos pacientes siguen infratratados y es preciso optimizar su uso. (AU)
