We conducted a case-control study searching for a possible role of environment in the risk of essential tremor (ET). We interviewed 142 ET patients and 284 age- and sex-matched controls about a family history of ET, exposure to environmental products containing lead, mercury, manganese, solvents and beta-carbolines, and exposure to agricultural work, well(More)
Sequencing data from Plasmodium ovale genotypes co-circulating in multiple countries support the hypothesis that P. ovale curtisi and P. ovale wallikeri are 2 separate species. We conducted a multicenter, retrospective, comparative study in Spain of 21 patients who had imported P. ovale curtisi infections and 14 who had imported P. ovale wallikeri(More)
PURPOSE To evaluate visual pathway structure and function in patients with clinical isolated syndrome (CIS) by using spectral-domain optical coherence tomography (OCT) and multifocal visual-evoked potentials (mfVEP), predicting CIS conversion to clinically definite multiple sclerosis (MS). METHODS This observational, longitudinal study assessed the eyes(More)
OBJECTIVE To objectively evaluate the visual function, and the relationship between disability and optic nerve dysfunction, in patients with multiple sclerosis (MS) and optic neuritis (ON), using multifocal visual evoked potentials (mfVEP). METHODS This observational, cross-sectional study assessed 28 consecutive patients with clinically definite MS,(More)
PURPOSE To evaluate visual function and its relationship to structure in adult amblyopic subjects. METHODS This observational, cross-sectional study included 24 adult amblyopes and 19 healthy subjects. The amblyopes were separated into three groups: anisometropic amblyopes (n = 15), strabismic amblyopes (n = 5), and strabismic amblyopes with anisometropia(More)
Dysthyroid optic neuropathy is the most serious, although infrequent (8-10 %) complication in Graves' orbitopathy (GO). It is known that early stages of compressive optic neuropathy may produce reversible visual field defects, suggesting axoplasmic stasis rather than ganglion cell death. This observational, cross-sectional, case-control study assessed 34(More)
Oligomers of Beta-amyloid (Aß) peptide are presumed to cause synaptic and cognitive dysfunction in Alzheimer's disease (AD). However, their contribution to other pathological features of AD remains unclear. To address the latter, we applied microinjections of Aß1-42 oligomers into the retrosplenial cortex of the rat. We observed that Aß1-42 induced a(More)
Cortical cholinergic dysfunction has been correlated with the expression and processing of beta-amyloid precursor protein. However, it remains unclear as to how cholinergic dysfunction and beta-amyloid (Abeta) formation and deposition might be related to one another. Since the M1- and M2 subtypes of muscarinic acetylcholine receptors (mAChRs) are considered(More)
