This paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices. A nonparametric analysis of consumer expenditure patterns suggests that Engel curves require quadratic terms in the logarithm of expendit...

AIM Although surgery for temporal lobe epilepsy (TLE) harbours a good prognosis, post-operative seizures may occur. Long-term, post-operative seizure follow-ups are rare but necessary to properly define outcome. METHODS Longitudinal, long-term, post-operative seizure follow-up in TLE patients with outcome analysed using Engel's classification. Three groups were considered according to the typ...

INTRODUCTION High resolution MRI findings suggestive of mesial temporal sclerosis (MRI-MTS) correlate with good outcome after surgery. However, a large group of patients present with normal brain MRI (N-MRI) and temporal lobe epilepsy (TLE). We aim to compare pre-operative ictal EEG patterns in predicting surgical outcomes in the population with MRI-MTS vs. N-MRI after selective anterior-mesial...
