Andraus, Maria Emilia Cosenza;Alves-Leon, Soniza Vieira;
Arquivos de Neuro-Psiquiatria , 2011, DOI: 10.1590/S0004-282X2011000600020
Abstract: more than 80 years after its introduction by hans berger, the electroencephalogram (eeg) remains as an important supplementary examination in the investigation of neurological disorders and gives valuable and accurate information about cerebral function. abnormal eeg findings may include ictal patterns, interictal epileptiform activity and non-epileptiform abnormalities. the aim of this study is to make an overview on the main non-epileptiform eeg abnormalities, emphasizing the pathologic findings and the importance of their recognition, excluding periodic patterns and eeg physiologic changes. scientific articles were selected from medline and pubmed database. the presence of non-epileptiform eeg abnormalities provide evidence of brain dysfunction that are not specific to a particular etiology and may be related to a number of disorders affecting the brain. although these abnormalities are not specific, they can direct attention to the diagnostic possibilities and guide the best treatment choice.

Abstract: O objetivo desse estudo foi avaliar a utilidade do SPECT cerebral interictal na localiza o do foco epileptogênico em 23 pacientes do Ambulatório de Epilepsias do Hospital Universitário Clementino Fraga Filho (HUCFF/UFRJ), com epilepsia do lobo temporal (ELT) de difícil controle e tomografia computadorizada (TC) do cranio normal, estudando a correla o entre SPECT interictal, eletrencefalograma (EEG) e, em 11 casos, ressonancia magnética (RM) do cranio, e comparar os resultados com os de outras seis séries da literatura. Doze (52,2%) pacientes apresentaram SPECT anormal. Entre esses, cinco (41,6% dos SPECTs anormais) apresentaram altera o unilateral ao SPECT do mesmo lado do EEG (hipoperfus o em 4 e hiperperfus o em 1), três (25% dos SPECTs anormais) apresentaram hipoperfus o bilateral ao SPECT e altera es também bilaterais ao EEG e 4 (33,3% dos SPECTs anormais) apresentaram hipoperfus o unilateral ao SPECT e EEG bilateral. A análise estatística fundamentou-se na lógica fuzzy. Os índices de correla o entre SPECT X EEG, SPECT X RM e SPECT X EEG X RM foram altamente significativos, com níveis de significancia de 0,01, p < 0,0005 e intervalo de 99% de confian a em todas as correla es. Os estudos de correla o entre as séries estudadas apresentaram resultados semelhantes entre si.
Periodic EEG patterns: importance of their recognition and clinical significance
Andraus, Maria Emilia Cosenza;Andraus, Cesar Fantezia;Alves-Leon, Soniza Vieira;
Arquivos de Neuro-Psiquiatria , 2012, DOI: 10.1590/S0004-282X2012000200014
Abstract: periodic electroencephalographic (eeg) patterns consist of discharges usually epileptiform in appearance, which occur at regular intervals, in critical patients. they are commonly classified as periodic lateralized epileptiform discharges (pleds), bilateral independent pleds or bipleds, generalized epileptiform discharges (gpeds) and triphasic waves. stimulus-induced rhythmic, periodic or ictal discharges (sirpids) are peculiar eeg patterns, which may be present as periodic discharges. the aim of this study is to make a review of the periodic eeg patterns, emphasizing the importance of their recognition and clinical significance. the clinical significance of the periodic eeg patterns is uncertain, it is related to a variety of etiologies, and many authors suggest that these patterns are unequivocally epileptogenic in some cases. their recognition and classification are important to establish an accurate correlation between clinical, neurological, laboratorial and neuroimaging data with the eeg results.

Abstract: Experimento de campo foi conduzido, nos anos agrícolas 1996/97 e 1997/98, para avaliar os efeitos de aplica es sucessivas de composto de lixo urbano sobre os teores de carbono organico, condutividade elétrica, pH e capacidade de troca de cátions (CTC) ao pH atual de um Latossolo Amarelo distrófico em que foi cultivada cana-de-a úcar. No primeiro ano agrícola, além dos tratamentos calagem + aduba o mineral e testemunha, o composto de lixo foi aplicado nas doses de 20, 40 e 60 Mg ha-1 (base seca). No segundo ano, o composto foi reaplicado nas doses de 24, 48 e 72 Mg ha-1. Todas as propriedades químicas do solo estudadas aumentaram com as doses do composto, em ambos os anos agrícolas. Os incrementos observados nesses atributos, da primeira para a segunda aplica o, foram significativos, exceto a condutividade elétrica, que, embora tenha aumentado logo após a aplica o do resíduo, n o atingiu níveis críticos e teve seus valores reduzidos com o tempo. Acúmulos nos teores de C organico do solo foram diretamente proporcionais às doses de aplica o. O aumento da CTC do solo foi conseqüência direta dos incrementos nos teores de C organico e nos valores de pH.
