RESUMO

INTRODUCTION: Epilepsy affects around 50 million people worldwide and is associated with lower quality of life scores, an increased risk of premature death, and significant socio-economic implications. The lack of updated evidence on current epidemiology and patient characterization creates considerable uncertainty regarding the epilepsy burden in Portugal. The study aims to characterize and quantify the epilepsy patients who have been hospitalized, with medical or surgical procedures involved, and to analyze their associated comorbidities and mortality rates. METHODS: A multicenter retrospective study was conducted using hospital production data of epilepsy patients. The study included all patients diagnosed with epilepsy-related International Classification of Diseases-9/10 codes between 2015 and 2018 in 57 Portuguese National Health Service (NHS) hospitals (n = 57 institutions). Patient characterization and quantification were done for all patients with an epilepsy diagnosis, with specific analyses focusing on those whose primary diagnosis was epilepsy. Baseline, demographic, and clinical characteristics were analyzed using descriptive statistics. RESULTS: Between 2015 and 2018, a total of 80,494 hospital episodes (i.e., patient visit that generates hospitalization and procedures) were recorded, with 18 % to 19 % directly related to epilepsy. Among these epilepsy-related hospital episodes, 13.0 % led to short term hospitalizations (less than 24 h). Additionally, the average length of stay for all these epilepsy-related episodes was 8 days. A total of 49,481 patients were identified with epilepsy based on ICD-9/10 codes. The median age of patients was 64 years (min: 0; max: 104), with a distribution of 4.8 patients per 1,000 inhabitants. From the total of deaths (9,606) between 2015 and 2018, 14% were associated with patients whose primary diagnosis was epilepsy, with 545 of these being epilepsy-related deaths. Among patients with a primary diagnosis of epilepsy, the most common comorbidities were hypertension (24%) and psychiatric-related or similar comorbidities (15%), such as alcohol dependance, depressive and major depressive disorders, dementia and other convulsions. CONCLUSION: This study showed similar results to other European countries. However, due to methodological limitations, a prospective epidemiological study is needed to support this observation. Furthermore, the present study provides a comprehensive picture of hospitalized epilepsy patients in Portugal, their comorbidities, mortality, and hospital procedures.

RESUMO

BACKGROUND AND PURPOSE: The art of diagnosis in clinical neurology requires attentive listening and careful observation. In certain situations, a fragment of the history or a physical sign may be so distinctive that it allows clinicians to evoke a specific diagnosis. This quick mental process was previously referred to as 'Augenblickdiagnose' ('diagnosis in the blink of an eye') in a seminal paper by Dr. William Campbell in 1998. We aimed to revisit this concept by providing additional clinical vignettes. METHODS: The authors wrote clinical vignettes using examples from their own clinical practice and performed a non-systematic review of influential neurology textbooks using the words 'pathognomonic' and 'highly suggestive'. RESULTS: Twenty examples from various fields of neurology are presented in a table, stratified by major fields of neurology. A short educational reflection is provided for each diagnosis considered. CONCLUSION: 'Augenblickdiagnose' is an engaging teaching resource that also contributes to 'neurophilia', that is, a fascination for neurology, perhaps increasingly in today's modern neurology practice. However, multiple cognitive biases underlying mental shortcuts may lead to an incorrect diagnosis. It is important to stress that good clinical practice in neurology requires taking a thorough history and performing a careful neurological examination.

RESUMO

BACKGROUND AND OBJECTIVES: The efficacy of deep brain stimulation of the anterior nucleus of the thalamus (ANT DBS) in patients with drug-resistant epilepsy (DRE) was demonstrated in the double-blind Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy randomized controlled trial. The Medtronic Registry for Epilepsy (MORE) aims to understand the safety and longer-term effectiveness of ANT DBS therapy in routine clinical practice. METHODS: MORE is an observational registry collecting prospective and retrospective clinical data. Participants were at least 18 years old, with focal DRE recruited across 25 centers from 13 countries. They were followed for at least 2 years in terms of seizure frequency (SF), responder rate (RR), health-related quality of life (Quality of Life in Epilepsy Inventory 31), depression, and safety outcomes. RESULTS: Of the 191 patients recruited, 170 (mean [SD] age of 35.6 [10.7] years, 43% female) were implanted with DBS therapy and met all eligibility criteria. At baseline, 38% of patients reported cognitive impairment. The median monthly SF decreased by 33.1% from 15.8 at baseline to 8.8 at 2 years (p < 0.0001) with 32.3% RR. In the subgroup of 47 patients who completed 5 years of follow-up, the median monthly SF decreased by 55.1% from 16 at baseline to 7.9 at 5 years (p < 0.0001) with 53.2% RR. High-volume centers (>10 implantations) had 42.8% reduction in median monthly SF by 2 years in comparison with 25.8% in low-volume center. In patients with cognitive impairment, the reduction in median monthly SF was 26.0% by 2 years compared with 36.1% in patients without cognitive impairment. The most frequently reported adverse events were changes (e.g., increased frequency/severity) in seizure (16%), memory impairment (patient-reported complaint, 15%), depressive mood (patient-reported complaint, 13%), and epilepsy (12%). One definite sudden unexpected death in epilepsy case was reported. DISCUSSION: The MORE registry supports the effectiveness and safety of ANT DBS therapy in a real-world setting in the 2 years following implantation. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that ANT DBS reduces the frequency of seizures in patients with drug-resistant focal epilepsy.

RESUMO

The Anterior Nucleus of Thalamus (ANT) Deep Brain Stimulation (DBS) has long been touted as the most effective DBS-target for interrupting seizures in focal refractory epilepsy patients. The ANT is primarily involved in cognitive tasks but has extensive reciprocal connections with motor-related regions, suggesting that it is also involved in motor-cognitive tasks. In this work, we aimed to assess the involvement of the ANT during voluntary upper limbs movements. For this purpose, we analyzed Local Field Potentials (LFPs) signals recorded during a movement protocol from one of the first epilepsy patients implanted with a Percept™ PC system, who performed a 5-day period of simultaneous video electroencephalography (vEEG) and Percept PC-LFPs recordings. We estimated time-frequency maps and performed event-related desynchronization (ERD) or synchronization (ERS) analysis and we found that synchronizations found in left hemisphere 7-17 Hz map corresponded to maximum hand rotations. Positive peaks on the ERD/ERS curve occurred at a similar frequency of the hand movements ([Formula: see text] against [Formula: see text]). These results suggested that the ANT may be involved in the execution of automatisms. Moreover, we found that ERD/ERS appeared approximately 2 seconds before the movement onset, as it was found on the EEG of healthy subjects performing the same protocol.

RESUMO

Deep brain stimulation of the Anterior Nucleus of the Thalamus (ANT-DBS) is an effective therapy in epilepsy. Poorer surgical outcomes are related to deviations of the lead from the ANT-target. The target identification relies on the visualization of anatomical structures by medical imaging, which presents some disadvantages. This study aims to research whether ANT-LFPs recorded with the PerceptTM PC neurostimulator can be an asset in the identification of the DBS-target. For this purpose, 17 features were extracted from LFPs recorded from a single patient, who stayed at an Epilepsy Monitoring Unit for a 5-day period. Features were then integrated into two machine learning (ML)-based methodologies, according to different LFP bipolar montages: Pass1 (nonadjacent channels) and Pass2 (adjacent channels). We obtained an accuracy of 76.6% for the Pass1-classifier and 83.33% for the Pass2-classifier in distinguishing locations completely inserted in the target and completely outside. Then, both classifiers were used to predict the target percentage of all combinations, and we found that contacts 3 (left hemisphere) and 2 and 3 (right hemisphere) presented higher signatures of the ANT-target, which agreed with the medical images. This result opens a new window of opportunity for the use of LFPs in the guidance of DBS target identification.

RESUMO

OBJECTIVE: Heart rate variability (HRV), an index of the autonomic cardiac activity, is decreased in patients with epilepsy, and a low HRV is associated with a higher risk of sudden death. Generalized tonic-clonic seizures are one of the most consistent risk factors for SUDEP, but the influence (and relative risk) of each type of seizure on cardiac function is still unknown. Our objective was to assess the impact of the type of seizure (focal to bilateral tonic-clonic seizure - FBTCS - versus non-FBTCS) on periictal HRV, in a group of patients with refractory epilepsy and both types of seizures. METHODS: We performed a 48-hour Holter recording on 121 patients consecutively admitted to our Epilepsy Monitoring Unit. We only included patients with both FBTCS and non-FBTCS on the Holter recording and selected the first seizure of each type to analyze. To evaluate HRV parameters (AVNN, SDNN, RMSSD, pNN20, LF, HF, and LF/HF), we chose 5-min epochs pre- and postictally. RESULTS: We included 14 patients, with a median age of 36 (min-max, 16-55) years and 64% were female. Thirty-six percent had cardiovascular risk factors, but no previously known cardiac disease. In the preictal period, there were no statistically significant differences in HRV parameters, between FBTCS and non-FBTCS. In the postictal period, AVNN, RMSSD, pNN20, LF, and HF were significantly lower, and LF/HF and HR were significantly higher in FBTCS. From preictal to postictal periods, FBTCS elicited a statistically significant rise in HR and LF/HF, and a statistically significant fall in AVNN, RMSSD, pNN20, and HF. Non-FBTCS only caused statistically significant changes in HR (decrease) and AVNN (increase). SIGNIFICANCE/CONCLUSION: This work emphasizes the greater effect of FBTCS in autonomic cardiac function in patients with refractory epilepsy, compared to other types of seizures, with a significant reduction in vagal tonus, which may be associated with an increased risk of SUDEP.

RESUMO

OBJECTIVE: Patients with epilepsy, mainly drug-resistant, have reduced heart rate variability (HRV), linked to an increased risk of sudden death in various other diseases. In this context, it could play a role in SUDEP. Generalized convulsive seizures (GCS) are one of the most consensual risk factors for SUDEP. Our objective was to assess the influence of GCS in HRV parameters in patients with drug-resistant epilepsy. METHODS: We prospectively evaluated 121 patients with refractory epilepsy admitted to our Epilepsy Monitoring Unit. All patients underwent a 48-hour Holter recording. Only patients with GCS were included (n = 23), and we selected the first as the index seizure. We evaluated HRV (AVNN, SDNN, RMSSD, pNN50, LF, HF, and LF/HF) in 5-min epochs (diurnal and nocturnal baselines; preictal - 5 min before the seizure; ictal; postictal - 5 min after the seizure; and late postictal - >5 h after the seizure). These data were also compared with normative values from a healthy population (controlling for age and gender). RESULTS: We included 23 patients, with a median age of 36 (min-max, 16-55) years and 65% were female. Thirty percent had cardiovascular risk factors, but no previously known cardiac disease. HRV parameters AVNN, RMSSD, pNN50, and HF were significantly lower in the diurnal than in the nocturnal baseline, whereas the opposite occurred with LF/HF and HR. Diurnal baseline parameters were inferior to the normative population values (which includes only diurnal values). We found significant differences in HRV parameters between the analyzed periods, especially during the postictal period. All parameters but LF/HF suffered a reduction in that period. LF/HF increased in that period but did not reach statistical significance. Visually, there was a tendency for a global reduction in our patients' HRV parameters, namely AVNN, RMSSD, and pNN50, in each period, comparing with those from a normative healthy population. No significant differences were found in HRV between diurnal and nocturnal seizures, between temporal lobe and extra-temporal-lobe seizures, between seizures with and without postictal generalized EEG suppression, or between seizures of patients with and without cardiovascular risk factors. SIGNIFICANCE/CONCLUSION: Our work reinforces the evidence of autonomic cardiac dysfunction in patients with refractory epilepsy, at baseline and mainly in the postictal phase of a GCS. Those changes may have a role in some SUDEP cases. By identifying patients with worse autonomic cardiac function, HRV could fill the gap of a lacking SUDEP risk biomarker.

RESUMO

INTRODUCTION: Although deep brain stimulation of the anterior nucleus of the thalamus (ANT-DBS) represents an established third-line therapy for patients with drug-resistant focal epilepsy, guiding reports on practical treatment principles remain scarce. METHODS: An Expert Panel (EP) of 10 European neurologists and 4 neurosurgeons was assembled to share their experience with ANT-DBS therapy. The process included a review of the current literature, which served as a basis for an online survey completed by the EP prior to and following a face-to-face meeting (Delphi method). An agreement level of ≥71 % was considered as consensus. RESULTS: Out of 86 reviewed studies, 46 (53 %) were selected to extract information on the most reported criteria for patient selection, management, and outcome. The Delphi process yielded EP consensus on 4 parameters for selection of good candidates and patient management as well as 7 reasons of concern for this therapy. Since it was not possible to give strict device programming advice due to low levels of evidence, the experts shared their clinical practice: all of them start with monopolar stimulation, 79 % using the cycling mode. Most (93 %) EP members set the initial stimulation frequency and pulse width according to the SANTE parameters, while there is more variability in the amplitudes used. Further agreement was achieved on a list of 7 patient outcome parameters to be monitored during the follow-up. CONCLUSIONS: Although current evidence is too low for definite practical guidelines, this EP report could support the selection and management of patients with ANT-DBS.

RESUMO

PURPOSE: To profile serum levels of high sensitivity Troponin I (hs-cTnI), B-Type Natriuretic Peptide (BNP), and high sensitivity C Reactive Protein (hs-CRP), after epileptic seizures in patients with focal drug-resistant epilepsy, relating the results to the revised SUDEP-7 inventory. METHODS: We prospectively evaluated patients admitted to our Epilepsy Monitoring Unit. hs-cTnI, BNP, and hs-CRP were measured at admission and after the first seizure. The revised SUDEP-7 Risk Inventory was calculated. The statistical significance level was set at 0.05. RESULTS: Fifty-eight patients were included (53.4 % female). The index seizure was a focal to bilateral tonic-clonic seizure (FBTCS) in 25.9 % of the patients, and 17.5 % had post-ictal generalized EEG suppression (PGES). After the seizure, 25.9 % had a significant (above 50 %) increase in hs-cTnI, 23.3 % in BNP, and 4.3 % in hs-CRP. About 40 % had cardiovascular risk factors (CRF), without known cardiac disease. The elevation of one biomarker did not compel the elevation of another. hs-cTnI increase was associated with FBTCS, PGES, longer seizures, maximal ictal heart rate, and HR change. Increases in BNP were associated with CRF. hs-CRP increase was associated with PGES. We found no significant association between SUDEP-7 and any biomarker increase. SIGNIFICANCE: Several patients had increases in biomarkers of myocardial necrosis/dysfunction after seizures, without significant association with the SUDEP-7 inventory. Different patterns of biomarkers' elevations point to multifactorial pathophysiologies hypothetically associated with incipient myocardial lesions. A larger cohort with follow-up data could help to clarify the clinical relevance of these findings.

RESUMO

This study aimed to characterize, clinically and neurophysiologically, a series of patients with gelastic seizures (GS), including both adults and children. We retrospectively collected patients with GS from epilepsy clinics of five tertiary hospital centres within a single country. Patients were selected through relatives'/caregivers' descriptions, home video and/or video-EEG monitoring. GS were identified through ictal semiology. Thirty-five patients were enrolled; 62.9% had initial GS in infancy, 14.3% in adolescence and 22.8% at adult age. Twenty-six had abnormal MRI: eight presented with hypothalamic hamartoma (HH) and 16 non-HH lesions that included different structural aetiologies and genetic, metabolic and immune aetiologies. All patients with HH had their first GS in infancy or adolescence. For the remaining aetiologies, GS started in infancy in 59.3%, in adolescence in 11.1% and at adult age in 29.6%. Video-EEG data was available for analysis in 11 patients, including seven patients with a non-HH MRI lesion. The ictal onset topography on scalp video-EEG was usually concordant with the MRI lesion (in 6/7 patients) and the most frequent ictal onset was fronto-temporal. In two patients, both video-EEG and MRI suggested a parietal and occipital epileptogenic zone. Aetiologies and patterns of affected topography unrelated to HH are common in patients with GS, and all age groups may manifest with this type of ictal semiology. This ictal manifestation has no lateralizing value and, despite a clear preponderance for hypothalamic, frontal and temporal lobe origins, other brain areas, namely the parietal and occipital lobes, should be considered.

RESUMO

When performing pre-surgical evaluation of patients with refractory epilepsy, the analysis of seizure semiology is one of the key elements used to generate a hypothesis about the location of the epileptogenic zone. Ictal kissing is a very rarely observed ictal automatism described in patients with temporal lobe epilepsy. We present a 62-year-old man who was referred to our epilepsy centre for comprehensive evaluation. During prolonged video-EEG monitoring, six focal-onset hyperkinetic seizures were registered. In five seizures, the patient repeatedly produced sonorous kisses "into the air". Initial ictal EEG pattern consisted of rhythmic theta or alpha activity at the right fronto-polar and fronto-medial electrodes. MRI depicted focal cortical dysplasia located in the right prefrontal medial cortex. This case suggests that ictal kissing can also occur in the setting of right frontal lobe epilepsy; we therefore believe that this observation expands the anatomo-clinical correlation for this rare ictal automatism.

RESUMO

Periodic limb movements (PLMs) may occur as a primary condition or be associated with other pathologies, such as sleep disorders. However, PLMs have not been described in comatose patients. We report the case of a 66-year-old man, with no history of sleep disorders, who presented PLMs during coma caused by an extensive right hemispheric abscess inducing midline shift. These movements were further characterized by video and electromyographic recordings, which displayed bilateral periodic bursts of the tibialis anterior muscles, occurring every 7 to 15 seconds, with no concomitant electroencephalographic correlate. After a long period of hospitalization, the patient eventually regained consciousness and PLMs seem to persist, only in sleep. To the best of our knowledge, this is the first report showing that PLMs may be observed in a setting where the networks supporting consciousness are lost, namely in a coma of structural etiology.

RESUMO

Background and purpose We evaluated two methods to identify mesial temporal sclerosis (MTS): visual inspection by experienced epilepsy neuroradiologists based on structural magnetic resonance imaging sequences and automated hippocampal volumetry provided by a processing pipeline based on the FMRIB Software Library. Methods This retrospective study included patients from the epilepsy monitoring unit database of our institution. All patients underwent brain magnetic resonance imaging in 1.5T and 3T scanners with protocols that included thin coronal T2, T1 and fluid-attenuated inversion recovery and isometric T1 acquisitions. Two neuroradiologists with experience in epilepsy and blinded to clinical data evaluated magnetic resonance images for the diagnosis of MTS. The diagnosis of MTS based on an automated method included the calculation of a volumetric asymmetry index between the two hippocampi of each patient and a threshold value to define the presence of MTS obtained through statistical tests (receiver operating characteristics curve). Hippocampi were segmented for volumetric quantification using the FIRST tool and fslstats from the FMRIB Software Library. Results The final cohort included 19 patients with unilateral MTS (14 left side): 14 women and a mean age of 43.4 ± 10.4 years. Neuroradiologists had a sensitivity of 100% and specificity of 73.3% to detect MTS (gold standard, k = 0.755). Automated hippocampal volumetry had a sensitivity of 84.2% and specificity of 86.7% (k = 0.704). Combined, these methods had a sensitivity of 84.2% and a specificity of 100% (k = 0.825). Conclusions Automated volumetry of the hippocampus could play an important role in temporal lobe epilepsy evaluation, namely on confirmation of unilateral MTS diagnosis in patients with radiological suggestive findings.

RESUMO

The clinical symptoms associated with chromosome 15q duplication syndrome manifest through a heterogeneous group of symptoms characterised by hypotonia, delay in motor skills and language development, cognitive and learning disabilities, autism spectrum disorder and refractory epilepsy. The late development of Lennox-Gastaut syndrome in patients with 15q11q13 duplication is a possibility that physicians should be aware of. We report the case of a 27-year-old man with a neurodevelopmental syndrome due to a 15q duplication, with intellectual disability, psychiatric disturbances, and an epileptic phenotype diagnosed as late-onset Lennox-Gastaut syndrome.

RESUMO

Vocalizations may occur in focal epileptic seizures, which typically arise from frontal and temporal regions. They are commonly associated with other motor phenomena such as automatisms, tonic posturing, or head version. We report on a patient whose seizures were documented by video-EEG monitoring, but in whom the observable ictal semiology consisted solely of a brief, monotonous vocalization. Ictal EEGs showed left frontal seizure patterns. Isolated vocalizations can constitute an ictal epileptic event and may be the only observable clinical manifestation of a left frontal lobe epilepsy.

RESUMO

A deficiência auditiva pode ser conseqüência de exposições a ruídos e/ou agentes ototóxicos. O objetivo do trabalho é abordar os métodos, as normas e as legislações pertinentes ao ruído ocupacional, além das diferenças históricas entre os limites de tolerância (LT). Discute-se a relação entre a Perda Auditiva Induzida pelo Ruído Ocupacional (PAIRO) e o nexo causal com a legislação trabalhista da época. São apresentados os resultados obtidos da exposição em nível de pressão sonora (NPS) elevado durante as atividades laborais. Utilizaram-se como exemplo três trabalhos: medição da exposição a NPS em danceterias, em consultório odontológico e a toque da campainha de um aparelho celular em diferentes posições. Neste trabalho foi relacionada uma possível perda auditiva devida ao aumento da suscetibilidade ao ruído de indivíduos expostos a substâncias ototóxicas encontradas em poluentes e medicamentos.

RESUMO

Busca-se propor uma fundamentação da psicoterapia corporal de inspiração reichiana dentro do quadro de referência da primeira teoria freudiana das pulsões. Tenta-se explicar os elementos próprios da abordagem reichiana a partir da idéia de uma dinâmica psíquica baseada no conflito entre pulsão e defesa. Também são discutidas, brevemente, algumas possibilidades de ampliação desse modelo a partir de propostas oriundas de outras abordagens

RESUMO

Este artigo aborda a questao da bioenergia, tambem chamada de energia vital ou forca vital, partindo de um ponto de vista da psicoterapia reichiana e neo-reichiana. Sao discutidos os fundamentos cientificos e epistemologicos deste conceito e investigadas suas conexoes com a Homeopatia, a Acupuntura, terapias alternativas e tradicoes espirituais orientais e ocidentais. Verifica-se que, mesmo entre os que defendem a existencia de uma bioenergia, sao multiplas as opinioes sobre o tema, sendo estas incompativeis entre si em pontos fundamentais. Conclui-se pela necessidade de aprofundamento do assunto, e sao propostos alguns caminhos para tal

RESUMO

O artigo apresenta resultados do teste CAGE para alcoolismo, para populaçäo de 15 a 59 anos de ambos os sexos, em amostra domiciliar estratificada por nível socioeconômico no Município de Säo Paulo. O inquérito abrangeu 1.914 domicílios, resultando 1.471 respostas válidas. Encontrou-se positividade de 12,6% para homens, 3,4% para mulheres e 7,8% no total. A distribuiçäo por renda, classe social e escolaridade mostrou tendência de maiores taxas de alcoolismo nos grupos sociais menos favorecidos. Além dessas variáveis, é analisada a distribuiçäo segundo idade, cor, estado marital e satisfaçäo de vida. Discute-se o valor do teste CAGE como instrumento por detecçäo do alcoolismo em ambos os sexos e comparando-se os resultados obtidos com estudos anteriores, concluindo-se por sua utilidade, com ressalvas

RESUMO

As doenças crônicas näo transmissíveis säo causa importante de morte no Brasil, principalmente nos grandes centros urbanos. Existem inúmeros fatores de risco relacionados a este tipo de doenças, cuja remoçäo, ou atenuaçäo, pode contribuir para o declínio da mortalidade. Descreve-se a metodologia do primeiro estudo multicêntrico abrangente realizado na América Latina sobre a questäo dos fatores de risco de doenças crônicas näo-transmissíveis. No Brasil o estudo foi realizado nos municípios de Säo Paulo, SP e Porto Alegre, RS. Säo apresentados resultados preliminares para o Município de Säo Paulo quanto à prevalência de hipertensäo arterial (22,3 por cento), tabagismo (37,9 por cento) obesidade (18,0 por cento), alcoolismo (7,7 por cento) e sedentarismo (69,3 por cento). Os resultados obtidos säo comprovados com dados existentes para o Brasil e outros países, e discute-se a relaçäo entre a magnitude dos diversos fatores de risco e a mortalidade por doenças cardiovasculares em Säo Paulo e alguns países desenvolvidos
