ABSTRACT

Febrile seizures (FS) affect almost 2-5 percent of children and factors related to an increase susceptibility of children to FS may involve an imbalance of inflammatory cytokines and genetic factors. FS had low morbidity, but may be associated with the occurrence of late chronic epilepsy. Here we describe factors related to FS and its possible correlation with SUDEP.


Crises febris (CF) afetam aproximadamente 2-5 por cento das crianças e os fatores envolvidos com essa maior susceptibilidade das crianças às CF podem estar relacionados com uma ação inadequada de citocinas inflamatórias, além de fatores genéticos. As CF têm baixa morbidade, mas podem estar associadas à ocorrência de epilepsia crônica. Nós discutiremos os fatores relacionados com CF, considerando-se sua possível associação com SUDEP.

ABSTRACT

People with epilepsy have an increased risk of dying prematurely and the most common epilepsy-related category of death is sudden unexpected death in epilepsy (SUDEP). SUDEP is mainly a problem for patients with chronic uncontrolled epilepsy. The ultimate goal of research in SUDEP is to develop new methods to prevent it and actions other than medical and surgical therapies that could be very useful. Nutritional aspects, i.e., omega-3 fatty acids deficiency, could have an interesting role in this scenario. Some animal and clinical studies have suggested that omega-3 fatty acids could be useful in the prevention and treatment of epilepsy and hence SUDEP. It has been ascertained that the only foods that provide large amounts of omega-3 are seafood (fish and shellfish); however, some fish are contaminated with methylmercury, which may counteract the positive effects of omega-3 fatty acids. Our update review summarises the knowledge of the role of fish consumption on epilepsy research.


Pessoas com epilepsia têm um risco aumentado de morrer de forma prematura e a causa mais comum de morte relacionada à epilepsia encontra-se na categoria de morte súbita inesperada em epilepsia (SUDEP). SUDEP é um problema significativo para pacientes com epilepsia crônica não controlada. O principal objetivo nas pesquisas em SUDEP é o desenvolvimento de métodos capazes de levar à sua prevenção e ações outras que não medicamentosas e cirúrgicas que podem ser úteis. Os aspectos nutricionais, como por exemplo, a deficiência do ácido graxo ômega-3 pode ter um papel interessante neste cenário. Alguns estudos animais e clínicos têm sugerido que os ácidos graxos ômega-3 podem ser úteis na prevenção e no tratamento da epilepsia e, consequentemente, na SUDEP. Os únicos alimentos que contêm grandes proporções de ômega-3 são os frutos do mar (peixes e mariscos). No entanto, alguns peixes podem estar contaminados com metilmercúrio, o que pode levar a um efeito contrário ao benefício trazido pelos ácidos graxos ômega-3. Aqui, resumimos o conhecimento do papel do consumo de peixe nas pesquisas em epilepsia.

ABSTRACT

1. Experimental models of carcinomatous lymphangitis have not been described. This is an important clinical entity which usually results in the patients' death, although its natural history is still controversial. This study was undertaken to investigate whether the pattern of lung involvement after Walker 256 tumor inoculation through the trachea is a good model of carcinomatous lymphangitis. 2. Fifty male Wistar rats were inoculated through the trachea with 2.5 x 10(6) Walker 256 tumor cells and killed in groups of 5 animals each at 6 h and on days 1, 3, 7, 14, 21, 28, 35, 45, and 60 of the experiment. The lungs and thoracic lymph nodes were examined by light microscopy. 3. There were no tumors in the 25 animals killed before the 21st day of the experiment. The remaining 25 rats were sacrificed after 3 weeks of the experiment; 52 per cent of them displayed thoracic lymph node metastases, and 40 per cent developed a mild carcinomatous lymphangitis. The lung involvement did not correlate with respiratory distress, tumor dissemination or additional histological abnormalities. 4. We conclude that invasion of the lung is possible after intratracheal tumor cell inoculation, and that spreading follows a lymphatic pattern. This finding establishes this approach as a viable experimental model of carcinomatous lymphangitis. New approaches to increase the intensity and frequency of lung involvement, as well as the development of respiratory distress should be pursued in order to improve the efficiency of this model

ABSTRACT

A epilepsia é uma patologia neurológica que afeta milhöes de pessoas em todo o mundo, sendo que 25 por cento destes, continuam apresetnado convulsöes, apesar do tratamento medicamentoso. Nas últimas décadas tem ocorrido um desenvolvimento importante nas pesquisas na área da fisiopatologia das epilepsias, mas seus mecanismos moleculares ainda säo desconhecidos. Ainda é difícil correlacionar aspectos clínicos das epilepsias com mecanismos neurais, porque o progresso nas técnicas de biologia molecular näo foram seguidos por uma evoluçäo concomitante da análise comportamental. Este trabalho tem como objetivo revisar a avaliaçäo comportamental nas pesquisas sobre epilepsia e sua correlaçäo com a biologia molecular
