RESUMO

Language disturbances are common manifestations of non-convulsive seizures in focal epilepsy. Ictal aphasia and speech arrest are the most representative. On the other hand, ictal paraphasia is a rare clinical manifestation of dominant temporal lobe epilepsy, with few cases reported in the literature. We describe a 73-year-old woman with focal onset unaware seizures presenting with phonemic paraphasias related to a left anterior temporal low-grade glioma. This ictal speech manifestation can be easily misdiagnosed and treated as other neurological or mental illnesses and can be considered a lateralizing sign in epilepsy when an appropriate anatomo - electro - clinical correlation is done.

RESUMO

OBJECTIVE: The objective of our study was to systematically summarize the published evidence of demographic, clinical, diagnostic imaging, and therapeutic characteristics of patients with multilocular cystic nephroma (MLCN). CONCLUSION: Cross-sectional imaging evaluation is important for suggesting the diagnosis of MLCN but has several limitations. The number of radical nephrectomies reported for MLCN encourages discussion concerning the utility of percutaneous presurgical biopsy and frozen-section intraoperative biopsy as a more conservative diagnostic approach.

RESUMO

Following an immune challenge, there is two-way communication between the nervous and immune systems. It is proposed that a neural reflex--the inflammatory reflex--regulates the plasma levels of the key proinflammatory cytokine TNF-α, and that its efferent pathway is in the splanchnic sympathetic nerves. The evidence for this reflex is based on experiments on anesthetized animals, but anesthesia itself suppresses inflammation, confounding interpretation. Here, we show that previous section of the splanchnic nerves strongly enhances the levels of plasma TNF-α in conscious rats 90 min after they received intravenous LPS (60 µg/kg). The same reflex mechanism, therefore, applies in conscious as in anesthetized animals. In anesthetized rats, we then determined the longer-term effects of splanchnic nerve section on responses to LPS (60 µg/kg iv). We confirmed that prior splanchnic nerve section enhanced the early (90 min) peak in plasma TNF-α and found that it reduced the 90-min peak of the anti-inflammatory cytokine IL-10; both subsequently fell to low levels in all animals. Splanchnic nerve section also enhanced the delayed rise in two key proinflammatory cytokines IL-6 and interferon γ. That enhancement was undiminished after 6 h, when other measured cytokines had subsided. Finally, LPS treatment caused hypotensive shock in rats with cut splanchnic nerves but not in sham-operated animals. These findings demonstrate that reflex activation of the splanchnic anti-inflammatory pathway has a powerful and sustained restraining influence on inflammatory processes.
