Síndrome de Sturge Weber - Qual o Tempo Ideal para Cirurgia?

O Síndrome de Sturge Weber é um síndrome neurocutâneo caracterizado pela presença de um angioma plano facial afectando o dermátomo do ramo trigeminal, associado a um angioma leptomeníngeo ipsilateral. Traduz-se habitualmente por epilepsia (> 90% dos casos (1)), de difícil controlo, hemiparésia e por vezes atraso mental. Os autores apresentam dois casos clínicos com algumas particularidades e fazem uma revisã...

Renal artery aneurysm: An endovascular treatment for a rare cause of hypertension

Renal artery aneurysms are a rare cause of secondary hypertension. Endovascular treatment with a polytetrafluoroethylene (PTFE)-coated stent can exclude aneurysms and treat hypertension. We report the case of a 23-year-old man with hypertension diagnosed three years earlier and in whom renal angiography revealed three aneurysms involving the right renal artery. A covered stent was implanted, resulting in succes...

Volatile compounds contribution of Hanseniaspora guilliermondii and Hanseniaspo...

This work aims to investigate the contribution of a selected non-Saccharomyces yeast species, Hanseniaspora guilliermondii, to higher alcohols, esters, fatty acids and heavy sulphur compounds composition of red wine. Red grape must vinifications of 100 l were performed and an inoculated fermentation with H. guilliermondii was compared to a spontaneous fermentation. The presence of apiculate yeasts was observed ...

Restless leg syndrome, sleep quality and fatigue in multiple sclerosis patients

We have tested the hypothesis that restless leg syndrome (RLS) is related to quality of sleep, fatigue and clinical disability in multiple sclerosis (MS). The diagnosis of RLS used the four minimum criteria defined by the International Restless Legs Syndrome Study Group. Fatigue was assessed by the Fatigue Severity Scale (FSS >27), quality of sleep by the Pittsburgh Sleep Quality Index (PSQI >6), excessive dayt...

Heavy sulphur compounds, higher alcohols and esters production profile of Hanse...

Hanseniaspora guilliermondii and Hanseniaspora uvarum were tested in grape must fermentations as pure and mixed starter cultures with Saccharomyces cerevisiae. In pure cultures, the specific growth rates found were 0.29 h⁻¹ for H. uvarum, 0.23 h⁻¹ for H. guilliermondii and 0.18 h⁻¹ for S. cerevisiae. No significant differences were observed between these values and those obtained in mixed cultures. Results pres...

Ground state energy of charged particles clusters by quantum Monte Carlo method

Using variational and diffusion Monte Carlo methods, we have calculated the ground state energy of spinless charged particles (for N < 10) interacting through a repulsive Coulomb potential, moving in two-dimensions and kept together by an external parabolic potential. Using a very simple trial wave function, we obtain results comparable to those of a sophisticated model of a quantum dot.
